[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention makes the device convenient for sampling by coordinating the structures such as the driving assembly, the supporting assembly and the sampling assembly. By placing the floating platform on the water surface of the river, the motor drives the transmission wheel to rotate through the belt, and the transmission wheel drives the bidirectional screw to rotate, so that the movable block moves along the limit rod, and the fixed ring is driven to move downward through the movable rod, and the fixed ring drives the sampling assembly to move downward, so that the sampling assembly can be placed at a fixed depth in the water, and water can enter the sampling bottle, so that the device is convenient for sampling;

[0018] The present invention achieves high stability of the device by cooperating structures such as a floating platform, a support assembly, an air intake assembly and a one-way valve. When the movable block moves toward the middle along the limit rod, the movable block drives the piston rod, so that negative pressure is generated in the movable cavity, so that the second piston moves downward and opens, and gas enters the movable cavity. After the sampling assembly takes water, the movable block moves in the opposite direction to pull the sampling assembly upward to reset. The movable block drives the piston rod to push at the same time, so that the second piston closes and the one-way valve opens, so that gas enters the air cavity, so that the air film expands and becomes larger, so that the buoyancy can be increased when the sampling assembly is filled with water, so that the sampling assembly can be kept away from water, and the stability of water taking can be improved.

[0019] The present invention achieves a good sampling effect by cooperating structures such as a floating platform and a sampling assembly. When the sampling assembly moves upward for sampling, the sampling bottle slides slightly downward under the action of gravity, and the first piston and the sampling bottle are closed by the elastic force of the first spring, thereby preventing leakage when taking water. In addition, the U-shaped structural design of the floating platform allows the floating platform to float on the water surface and surround the sampling assembly, which can effectively prevent the oil layer or garbage floating on the water surface from entering the sampling bottle, thereby achieving a better sampling effect of the device.

Every two movable blocks 301 are slidably connected to the limit rod 304. The two ends of the movable rod 302 are respectively hinged to the movable block 301 and the fixed ring 303. The side of the movable block 301 away from the fixed ring 303 is fixedly connected to the piston rod 305. One of the fixed rings 303 is fixedly connected to the push rod 307 through the connecting rod 306.

[0032] The sampling assembly 4 includes a sampling bottle 401, a first support plate 402, a first spring 403 and a first piston 404. The sampling bottle 401 is sleeved in the middle of the fixing ring 303, the first support plate 402 is fixedly connected to the inside of the sampling bottle 401, and the two ends of the first spring 403 are respectively fixedly connected to the first support plate 402 and the first piston 404;

[0033] By placing the floating platform 1 on the water surface of the river, the motor 201 drives the transmission wheel 203 to rotate through the belt 202, and the transmission wheel 203 drives the bidirectional screw 204 to rotate, so that the movable block 301 moves along the limit rod 304, and the fixed ring 303 is driven to move downward through the movable rod 302, and the fixed ring 303 drives the sampling component 4 to move downward, so that the sampling component 4 can be placed in the water, and water can enter the sampling bottle 401, making the device easy to sample.

[0034] like Figures 2 to 4 As shown, an active cavity 102 and a connecting pipe 103 are provided inside the floating platform 1, an air film 6 is fixedly connected to the bottom of the floating platform 1, a sealed air cavity 101 is formed between the floating platform 1 and the air film 6, a piston rod 305 is movably connected to the inside of the active cavity 102, and the connecting pipe 103 connects the air cavity 101 and the active cavity 102.

[0035] The air intake assembly 5 includes an air bleed pipe 501, a second piston 502, a second spring 503 and a second support plate 504. The air bleed pipe 501 is fixed to the top of the floating platform 1. The two ends of the second spring 503 are respectively fixed to the second support plate 504 and the second piston 502. The second support plate 504 is fixed to the inside of the floating platform 1. A one-way valve 8 is arranged inside the connecting pipe 103. The air bleed pipe 501 is an L-shaped structure, and the opening of the air bleed pipe 501 faces the support assembly 3. The top of the second spring 503 is sealed and clamped with the connecting pipe 103.

[0036] An exhaust assembly 7 is provided on one side of the floating platform 1. The exhaust assembly 7 includes a pressing plug 701 and a third spring 702. The pressing plug 701 is movably sealed and connected to the floating platform 1. The two ends of the third spring 702 are respectively fixed to the floating platform 1 and the pressing plug 701. When the movable block 301 moves toward the middle along the limiting rod 304, the movable block 301 drives the piston rod 305, so that negative pressure is generated in the movable chamber 102, so that the second piston 502 moves downward and opens, and the gas enters the movable chamber 102. After the sampling assembly 4 takes water, the sampling assembly 4 is pulled upward and reset by the reverse movement of the movable block 301. The movable block 301 simultaneously drives the piston rod 305 to push, so that the second piston 502 is closed, and the one-way valve 8 is opened, so that the gas enters the air cavity 101, so that the air film 6 expands and becomes larger, so that the buoyancy can be increased when the sampling assembly 4 is filled with water, so that the sampling assembly 4 can not contact with water, so as to improve the stability of water collection.

[0037] After the device is taken out of water, by pressing the push plug 701, due to the high air pressure inside the air cavity 101, a part of the gas inside the air cavity 101 can be discharged from the exhaust component 7 through the elastic action of the air membrane 6, thereby stabilizing the air pressure in the air cavity 101, thereby facilitating the next use.

[0038] like Figure 1 and Figure 2 , Figures 4 to 6 As shown, both ends of the limit rod 304 are fixedly connected to the floating platform 1, a rubber layer is arranged inside the fixed ring 303, one end of the piston rod 305 close to the movable block 301 is movably connected to the floating platform 1, the middle part of the first piston 404 is in contact with the top rod 307, the floating platform 1 is U-shaped and made of lightweight material, the air film 6 is made of an elastic sealing film, the fixed ring 303 close to the U-shaped opening is lower than the other fixed ring 303, the two movable rods 302 are inclined toward the fixed ring 303, and the bidirectional screw 204, the limit rod 304 and the piston rod 305 are arranged in sequence from top to bottom;

[0039] Due to the friction of the rubber layer, after the sampling assembly 4 is inserted into the fixing ring 303, the sampling assembly 4 can be effectively limited and fixed, and the push rod 307 can press against the first piston 404, so that the opening of the sampling assembly 4 is opened, allowing water to enter the sampling bottle 401. Because the fixing ring 303 at one end is lower than the fixing ring 303 at the other end, when the sampling assembly 4 moves upward for sampling, the sampling bottle 401 slides slightly downward due to the action of gravity, and the elastic force of the first spring 403 makes the first piston 404 and the sampling bottle 401 close, thereby preventing leakage when taking water. In addition, through the U-shaped structure design of the floating platform 1, the floating platform 1 floats on the water surface and surrounds the sampling assembly 4, which can effectively prevent the oil layer or garbage floating on the water surface from entering the sampling bottle 401, thereby making the sampling effect of the device better.

[0040] The working principle and use process of the present invention:

[0041] First, the floating platform 1 is placed on the river surface, the motor 201 drives the transmission wheel 203 to rotate through the belt 202, and the transmission wheel 203 drives the bidirectional screw 204 to rotate, so that the movable block 301 moves along the limit rod 304, and the movable rod 302 drives the fixing ring 303 to move downward, and the fixing ring 303 drives the sampling assembly 4 to move downward, so that the sampling assembly 4 can be placed in the water, and water can enter the sampling bottle 401;

[0042] When the movable block 301 moves toward the middle along the limit rod 304, the movable block 301 drives the piston rod 305, so that negative pressure is generated in the movable chamber 102, so that the second piston 502 moves downward and opens, and the gas enters the movable chamber 102. After the sampling component 4 takes water, the movable block 301 moves in the opposite direction to pull the sampling component 4 upward to reset. The movable block 301 also drives the piston rod 305 to push, so that the second piston 502 is closed, and the one-way valve 8 is opened, so that the gas enters the air chamber 101, so that the air film 6 expands and becomes larger, so that the buoyancy can be increased when the sampling component 4 is filled with water, so that the sampling component 4 can complete the operation without contacting the water.
