The top of the installation box 2 is fixedly installed with the handle, so that the whole device is convenient to carry and move. One side of the installation box 2 is fixedly installed with the suction pump 4, and the suction end of the suction pump 4 extends into the installation box 2 and is fixedly installed with the support cover 3. The support cover 3 is fixedly connected with the inner wall of the installation box 2, and is used for supporting and fixing the subsequent collection mechanism.

[0033] The collection mechanism is specifically composed of a sampling box 7, the sampling box 7 is clamped in the support cover 3, and one side of the sampling box 7 extends into the installation box 2. In order to support the sampling box 7, the installation box 2 is fixedly installed with the support ring 6, and the sampling box 7 penetrates through the support ring 6 and cooperates with the support ring 6.

[0034] In order to close the sampling box 7 and facilitate disassembly, a cover plate mechanism is designed. The cover plate mechanism includes a cover plate 13 clamped with one side of the opening of the installation box 2. One side of the cover plate 13 is fixedly provided with an external threaded disc 20, and an internal threaded ring 12 is fixedly installed in the sampling box 7. When one side of the external threaded disc 20 extends into the internal threaded ring 12, the cover plate 13 and the sampling box 7 can be tightly connected by threaded connection, so as to close the sampling box 7. In addition, two arc-shaped clamping strips 14 are symmetrically fixedly installed on the cover plate 13, and a baffle 16 is fixedly installed at one end of the arc-shaped clamping strip 14. Two clamping frames 15 are symmetrically fixedly installed on the installation box 2, and the clamping frame 15 is movably clamped with the arc-shaped clamping strip 14. In order to further enhance the stability of the connection, the inner wall of one side of the clamping frame 15 is slidably connected with a plug rod 17, and one end of the plug rod 17 can extend into the insertion slot on the arc-shaped clamping strip 14, so as to realize clamping. The plug rod 17 is sleeved with a second extension spring 18 located outside the clamping frame 15, and the two ends of the second extension spring 18 are fixedly connected with the plug rod 17 and the clamping frame 15.

A moving cover 26 is slidably connected in the blocking pipe 24, and two second flow holes 27 are arranged on the two side bottom inner walls of the moving cover 26. When the first flow hole 25 communicates with the second flow hole 27, water can flow into the moving cover 26 through the two holes. The top of the moving cover 26 extends above the blocking pipe 24, and two limiting rods 28 are symmetrically and slidably connected on the moving cover 26.

[0036] In use, first, the suction force is generated by starting the suction pump 4, at this time, the moving cover 26 is moved upward under the action of the suction force, so that the first flow hole 25 and the second flow hole 27 are communicated. Then, the support box 22 is lowered to the specified depth of the water collection area, at this time, the water is sucked into the support box 22, and flows into the moving cover 26 through the first flow hole 25 and the second flow hole 27. After that, under the conveying action of the hose 21 and the docking pipe 19, the water sample to be collected is sucked into the sampling box 7. In order to overcome the buoyancy of the support box 22 and enable the support box 22 to be stably moved downward, the suction mechanism further comprises a support frame 30 and a plurality of counterweight discs 32. The plurality of counterweight discs 32 are sleeved on the support frame 30 and are clamped and matched with the positioning protrusions 31 through the clamping grooves 33.

The closure assembly comprises a docking cover 8 fixedly installed on the inner wall of one side of the sampling box 7, and the docking cover 8 is connected with the jack. The top inner wall and the bottom inner wall of the docking cover 8 are provided with second flow holes, and the second flow holes are connected with the first flow holes on the inner wall of the push cover 5 on the cover 3. The docking cover 8 is closely and slidably connected with an enclosing plate 9, one side of the enclosing plate 9 is fixedly installed with a moving rod 10, one end of the moving rod 10 penetrates through the inner wall of one side of the docking cover 8 and extends into the sampling box 7. A first extension spring 11 is sleeved on the moving rod 10 and located in the sampling box 7, and the two ends of the first extension spring 11 are fixedly connected with the docking cover 8 and the moving rod 10. When the sampling box 7 and the cover 3 are clamped, the push cover 5 is inserted into the docking cover 8 and pushes the enclosing plate 9 to move, thereby driving the moving rod 10 to move and making the first extension spring 11 in a stressed state. At this time, the first flow hole and the second flow hole are connected, and the suction pump 4 can be started to suck water into the sampling box 7.
