A 25 is also installed on the upper end surface of the upper shell 20. 25 is electrically connected to the main battery 23 and the auxiliary battery 24. Through direct sunlight, 25 collects solar energy to charge the main battery 23 and the auxiliary battery 24. Moreover, the auxiliary battery 24 is charged first during the charging process. After the auxiliary battery 24 is full, the main battery 23 can continue to be charged. When discharging, the main battery 23 is discharged first. After the main battery 23 is discharged, the auxiliary battery 24 is directly discharged. 26 is fixed on the outer peripheral side of the upper shell 20, which can be easily taken by the staff and can also be used to balance the overall equipment.

[0030] An air cavity system is provided inside the upper shell 20 and the lower shell 10, and an air cavity system is formed between the outlet cavity 21, the arc cavity 12, the connecting cavity 14 and the air guide cavity 17. At least two arc cavities 12 and an electrolytic cavity 15 are provided in the lower shell 10. The arc cavity 12 is provided around the electrolytic cavity 15. The tops of the arc cavities 12 are connected together through the connecting cavity 14. The upper side of the electrolytic cavity 15 is connected with an air guide cavity 17. The air guide cavity 17 extends into the connecting cavity 14 and is connected thereto. An auxiliary cavity 18 is also provided through the middle part of the air guide cavity 17. The auxiliary cavity 18 is connected to the arc cavities 12 on both sides. At least two outlet cavities 21 are provided at the side of the upper shell 20. The outlet cavity 21 is connected to the connecting cavity 14, and the other side of the outlet cavity 21 is connected to the outside world. The bottom of the arc cavity 12 is also connected to The drainage chamber 13 is connected to the outside of the lower shell 10, and the arc-shaped chamber 12 is also connected to the bottom of the electrolysis chamber 15. An electric plate 16 is installed inside the electrolysis chamber 15, wherein two electric plates 16 are provided, which are respectively connected to the positive and negative electrodes of the auxiliary battery 24. The seawater can be decomposed through the positive and negative electrodes and the salty seawater to generate water-insoluble gas for gas filling of the entire air cavity system. The entire air cavity system can be used to change the overall buoyancy of the equipment. After the power of the equipment is used up, the buoyancy of the equipment can be automatically increased, so that the equipment floats to the sea surface and is charged by direct sunlight. After charging, the equipment can automatically deflate to reduce the buoyancy of the equipment, so that the equipment re-enters the seabed and suspends, so as to monitor the growth status and distribution of the seabed fish.

[0031] A slider 11 is slidably arranged inside the arc cavity 12. The interior of the slider 11 is hollow. The thickness of the slider 11 is greater than the diameter of the auxiliary cavity 18. A raised ring is provided on the interior of the arc cavity 12 near the connecting cavity 14 to prevent the slider 11 from entering the connecting cavity 14 and affecting the gas from entering the outlet cavity 21. The slider 11 can be pushed to move by the air pressure generated when the gas gathers, so that the seawater in the arc cavity 12 can be squeezed out from the drainage cavity 13, and the squeezed water will also generate a certain thrust, which can make the entire device float faster.

[0032] A sealing assembly is also installed in the outlet chamber 21, and the sealing assembly includes a sealing block 30 and a sealing plug 33, wherein a sealing through hole 31 is opened in the sealing block 30, and the sealing plug 33 is connected to one side end face of the sealing block 30 through a sealing spring 34, and the sealing block 30 is located at the outlet of the outlet chamber 21, and an arc-shaped groove is arranged inside the sealing through hole 31, and the sealing plug 33 is conical, and a convex block 35 is also arranged on its outer peripheral side, and the convex block 35 cooperates with the arc-shaped groove, and enters the sealing through hole through the sealing plug 33. 31, its outlet can be sealed, and the sealing plug 33 is hollow inside, and the buoyancy it generates is greater than the elastic force of the sealing spring 34. The sealing assembly also includes an electromagnet 32, which is arranged on the side of the sealing plug 33 away from the sealing block 30. The electromagnet 32 ​​is electrically connected to the main battery 23 through a wire, and is started after the main battery 23 and the auxiliary battery 24 are fully charged, and is automatically turned off after being started for a period of time. After being started, the electromagnet 32 ​​generates magnetic force to absorb the sealing plug 33 and stretch the sealing spring 34.

[0033] The overall weight of the lower shell 10 is greater than that of the upper shell 20. Also, because the cavity inside the battery cavity 22 is not connected to other cavities, it has a certain buoyancy, which can keep the upper shell 20 on top when the device is in the sea.

[0034] Working principle: In the process of electrolyzing water, direct current is usually required, and sodium chloride is added to the water to increase its electrical conductivity, and then gas can be generated at its positive and negative electrodes. When the device is in use, the device can be directly placed on the sea surface at the corresponding position. Then, under normal conditions, under the elastic force of the sealing spring 34, the sealing plug 33 and the sealing block 30 are in a separated state, so that the entire air cavity system is in a state of communication with the outside world. Then, after the device is placed in the water, the seawater will gradually fill the entire air cavity system. Then, at this time, the weight of the device is greater than its buoyancy, and it will slowly enter the seabed until it reaches a suspended state. In the process of seawater filling, since the slider 11 is hollow, it will gradually slide to the uppermost end of the arc cavity 12, and then when the outlet cavity 21 is gradually filled, the sealing plug 33 will also generate buoyancy due to its hollowness, and its buoyancy will be greater than the elastic force of the sealing spring 34, so that the sealing plug 33 can enter the sealing through hole 31 and block the sealing through hole 31, but at this time the protruding block 35 has not entered the arc groove in the sealing through hole 31.

[0035] At this time, the equipment can monitor the seabed through the monitor 43, and can remotely adjust the position of the monitor 43 by adjusting the motor to achieve 360° monitoring, with a wider monitoring range. When the power in the main battery 23 is used up by the adjusting motor, the auxiliary battery 24 can be discharged, and the auxiliary battery 24 is electrically connected to the electric plate 16, and gas can be generated by electrolyzing seawater. The gas will float up and gather in the outlet chamber 21 and the connecting chamber 14. At this time, the pressure on the seabed is relatively large, which will compress the gas in the outlet chamber 21 and generate thrust, so that the raised block 35 on the sealing plug 33 is pushed into the arc-shaped groove to get stuck, and it will not be easily opened. As the gas gathers, it can gather into the arc chamber 12 through the connecting chamber 14. At this time, the gas can push the slider 11 in the arc chamber 12 to push the sea. Water is discharged from the drainage chamber 13, and as the gas in the air cavity system increases, the buoyancy of the equipment will increase, so that it will float up until it moves to the sea surface. At this time, there is still gas in the air cavity system, and the drainage chamber 13 is below the sea surface. The outlet chamber 21 is sealed by the sealing plug 33, and the gas will not be discharged. The equipment will always float on the sea surface. At this time, the main battery 23 and the auxiliary battery 24 can be charged through 25. When both are fully charged, the electromagnet 32 ​​can be started to be energized, and the sealing plug 33 can be adsorbed to be pulled out from the sealing through hole 31. At this time, the air cavity system is opened, the gas is discharged, and the seawater refills the entire air cavity system. At this time, the equipment will continue to dive to the seabed and continue to work, so the equipment can be continuously operated at sea. Unless maintenance is required, it can be uninterruptedly charged by itself to monitor the fish schools on the seabed.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
