The Black Tech Life of Scum

Chapter 118: : Electric Eel (1)

Zhang Yifan's idea is actually very simple. Now, for the time being, there is no way to break through some difficulties and reflect the military value. Then, go to the direction of pure civilian use.

There are many civilian areas that require underwater operations:

For example, in the aquaculture industry, the living status of underwater fishes can be observed through this rattlesnake robot;

Is it infected with some germs, harmful fish such as scavengers, etc .;

Slightly modified can also replace some manual shallow sea operations, such as sea urchin fishing, shellfish picking, etc .;

It can also be used in shallow sea scenic areas, so that tourists can enjoy the beautiful scenery of the sea bottom without the need to take risks and buy expensive oxygen cylinders ..

Of course, it can also be used to check cages and other operations .....

With direction and ideas, Zhang Yifan naturally drew up his sleeves and started to work;

The rattlesnake's volume has been shrinking again and again-there is no way, if it is military, it doesn't matter if it is larger or heavier, as long as one person can handle it, it will be fine

But for civilian use, it weighs ten kilograms and has a length of two meters, which is a burden. Anyone who wants to buy it must weigh it;

The housing does not need to consider any composite material, it is directly plastic and rubber, which is waterproof and corrosion resistant;

This has another benefit: the cost can be reduced a lot;

In two days, the first prototype was made and successfully passed the waterproof test in the hotel bathtub ...

In order to avoid underwater biological interference testing, or damage caused by underwater robots or even loss;

After careful consideration, Zhang Yifan added a boost discharge circuit to it, which is simply the principle of an electric fish machine or an electric eel.

The first outdoor test has begun;

The test site was a fishing ground on the outskirts of Quancheng. The area of ​​the fishing ground was small, covering an area of ​​about one acre;

The charges are not expensive. A pole costs 20 yuan, a mixed bait costs 10 yuan, and the fish caught is weighed and taken away;

The price of fish is 20% to 30% more expensive than the price in the market, and there is no need to deal with it. Even if you go to the aquatic market to pull fish back and spend some water in this pond, you can make a lot of money;

Zhang Yifan thinks that the boss is still a little business-minded, and the fishermen sell this account. The joy of fishing is originally a process of fishing, not how much is caught;

I found a corner in the pond that the boss couldn't notice. Everyone sat on the small bench. Gao Yong and Lexus started to open the pole, put the line, and measured the water depth ...

At this time, Wang Beibei also quietly started the robot and put it in the water ....

The water quality of the fishing ground is not clean, and even a little muddy. This is because many fishermen like to nest before fishing.

Some of the materials used for making nests are rice with white wine, some use fish feed, and even many fishermen will put their unused bait into the water to feed the fish when they close the pole;

This caused a lot of floating objects in the water, and the inflow and drainage of the pond were too small, so the water could not be cleaned naturally;

This also caused a lot of trouble for Zhang Yifan's observation. The underwater visibility was low. Even if the auxiliary lighting was turned on, it was only two or three meters away, and it was a bit fuzzy;

But this is also good. If you can pass the test under such harsh conditions, other environments can naturally cope with it ...

As a result, the light green 'water snake' slowly glides at a depth of about ten centimeters from the bottom of the water, and finally quietly stops less than twenty centimeters by the edge of Gao Yong's fishhook;

In order to confirm whether the fishhook was Gao Yong, Wang Beibei who was watching on the side also deliberately moved his lever to confirm;

Because a large part of the profit of the fishing farm comes from the fish bought by fishermen, the fish stocking density in the pond is very high. Of course, they are all worthless tilapia and catfish (grass carp);

Within two minutes, Zhang Yifan's mobile phone screen showed that several curious fish had been surrounded by the two fishhooks on Gao Yong's one ...

Then, a tilapia began to peck the bait on the fishhook, and a grass carp lay on the mouth not far from the lowest hook, sucking and sucking ...

When Gao Yong saw the fish mark falling and falling, he knew that the fish was coming. When the fish mark fell again, he suddenly lifted the rod, and then two empty hooks were pulled out of the water ... The fish ran away ...

Then he continued to bait and hooked in the original place ... an expression waiting for a good show ...

Then he sighed again: "Oh, almost ..."

Then he was still interested in bait and hooked ...

Zhang Yifan looked at the screen. Because the fish was frightened, he quickly ran away and stirred up the sediment and other impurities at the bottom of the water. The front of the camera was again turbid and speechless;

Gao Yong's fishing skills really have a lot of room for improvement. He has even wanted to control the robot several times to hang the fishhook to the fish's mouth--seeing it like this is really anxious for him, especially to see it live. Underwater conditions;

Gao Yongle is not tired and has no shame, because the Lexus next to him is the same as him, although he has not raised a lot of shots, he has also found nothing;

Zhang Yifan began to lose interest in Gao Yong's fishhook. He controlled the 'water snake' and searched along the bottom of the fishing ground for about three or four meters ....

When I saw a fish pecking at a fishhook ~ www.wuxiaspot.com ~, I came forward to help others, and suddenly accelerated sharply, hitting the fishhook into the mouth of the fish-anyway. The water snake's head is smooth and not afraid of being caught by a fishhook ...

This approach is also very beneficial, it is easy for him to know exactly where the 'water snake' is currently located:

Just look at the cheers of the fish. The approximate position of the 'water snake' is actually displayed on the mobile phone, but it is obviously not as accurate as those cheers of the fish;

Zhang Yifan did not operate for half an hour like this, and the fishing ground was almost boiling. Fishing for fish was a happy thing, after all, there was gain;

Even the boss was surprised. The fish on this fishing ground were fed by fishermen and fished fine. Generally, it would not be so high if it was not put on a batch of new fish from the fish pond. Fish rate

For unknown reasons, he can only attribute the cause to the care of God of Wealth ... he could never imagine that there was a live thunder under the water;

When Zhang Yifan controlled the ‘water snake’ and ran along the fishing ground and returned to the original point, when he found that Gao Yong and Lexus had found nothing, he thought of the trick again and helped them to avoid letting them air force;

However, the teammates' cooperation was really inadequate, and he clearly saw on the screen that he had hit the fishhook into the mouth of the fish, but Gao Yong still found nothing and raised the fish;

After repeated failures, Zhang Yifan gave up and said directly to Wang Beibei, "Xiaobei, you fiddle with the net bag for fishing, and I'll give you some big ones!"

Then, he pressed a key that was never pressed on that screen ... the electric eel ...
