The buoyancy of the buoyancy tank 3 in the water is adjusted. At the same time, it is also convenient to fill or discharge air into or out of the buoyancy tank 3, change the air pressure in the buoyancy tank 3, so that water can smoothly enter and discharge the buoyancy tank 3, and improve the smoothness of buoyancy adjustment. The mounting frame 4 includes a connecting frame 403 that matches the buoyancy tank 3. The connecting frame 403 is fixedly connected to the lower part of the mounting plate 401. By utilizing the cooperation between the mounting plate 401 and the connecting frame 403, the buoyancy tank 3 is stably installed on the pump body 1 to achieve stable cooperation between the buoyancy tank 3 and the pump body 1. The buoyancy of the buoyancy tank 3 is quickly adjusted during use to adjust the position of the pump body 1 suspended in the water. A connecting half sleeve 402 that matches the suction pipe 2 is provided on the mounting plate 401, which is convenient for stably connecting the mounting plate 401 to the suction pipe 2.

[0021] like Figure 1 and Figure 2 As shown, in some embodiments, a solenoid valve is installed on the water pipe 301 at the lower part of the buoyancy tank 3, which is convenient for controlling the on and off of the water pipe 301, so that water can smoothly discharge the buoyancy tank 3 from the water pipe 301, or enter the buoyancy tank 3 from the water pipe 301, and the inflation pipe 302 at the upper part of the buoyancy tank 3 is connected to the air pump 303, and the air pump 303 is arranged on the outer shell at the upper part of the pump body 1 to ensure the stable installation of the air pump 303. During operation, air is input into the buoyancy tank 3 from the inflation pipe 302 to increase the air pressure in the buoyancy tank 3, and water is discharged from the buoyancy tank 3 to increase the buoyancy of the buoyancy tank 3. The upper end of the exhaust pipe 304 extends to one side of the air pump 303, and the exhaust pipe 304 and the inflation pipe 302 are both provided with solenoid valves, which are convenient for discharging the air in the buoyancy tank 3 during use, reducing the air pressure in the buoyancy tank 3, allowing water to enter the buoyancy tank 3, reducing the buoyancy of the buoyancy tank 3, and then realizing the debugging operation of the suspended position of the pump body 1 in water by debugging the buoyancy size.

During the water intake process of the buoyancy box 3, the solenoid valve on the inflation pipe 302 is closed, and the solenoid valves on the water pipe 301 and the exhaust pipe 304 are opened, and the air in the buoyancy box 3 is discharged from the water pipe 301. The exhaust pipe 304 is discharged, and the water enters the pontoon 3 from the water pipe 301, which increases the mass of the pontoon 3 and reduces the buoyancy. The connecting rod arranged on the upper part of the connecting frame 403 passes through the placement plate 401 and is fixedly connected to the fixing rod 404. The fixing rod 404 is placed on the upper part of the placement plate 401. The connection frame 403 is stably connected to the lower part of the placement plate 401 by the cooperation between the fixing rod 404 and the connecting rod. At the same time, the connecting frame 403 is used as a frame for installing the pontoon 3, so that it can be stably installed on the placement frame 4, so as to achieve the purpose of stable use, and the two adjacent ones are The connecting half sleeves 402 on the mounting plates 401 are spliced ​​and combined to form an annular sleeve that is sleeved on the outer wall of the suction pipe 2.
