[0058] like Figures 1 to 8 As shown, the water inlet square tube 21 includes: a pressure hole 211, which is opened on one side of the water inlet square tube 21 and is used to balance the air pressure; a second water inlet hole 213, which is opened on one side of the water inlet square tube 21; a sealing tube 41 base, which is located between the second water inlet hole 213 and the first water inlet hole 11 and is connected to the inner wall of the water inlet square tube 21, and a sealing groove 2121 is opened on the side of the sealing tube 41 base close to the second water inlet hole 213.

[0059] In the embodiment of the utility model, the second water inlet hole 213 is a square hole and is opened on the side of the water inlet square tube 21 away from the inner wall of the water storage tank body 1; the pressure-through hole 211 ensures that the air pressure in the pressure limiting component 23 is the same as the air pressure in the water storage area of ​​the water storage tank body 1; the outer wall of the base of the sealing tube 41 is welded to the inner wall of the water inlet square tube 21 and is close to the side of the second water inlet hole 213 close to the first water inlet hole 11; in actual application, water flows through the base of the sealing tube 41 and flows from the second water inlet hole 213 into the water storage area of ​​the water storage tank body 1.

[0060] like Figures 1 to 8 As shown, the pressure limiting assembly 23 includes: a pressure-bearing block 231, which is located on the base of the sealing tube 41 and connected to the water inlet square tube 21, and a sealing rubber ring 2311 is provided on the side of the pressure-bearing block 231 close to the base of the sealing tube 41 and connected to the sealing groove 2121; a first fixing ring 232, one side of which is fixedly connected to the side of the pressure-bearing block 231 away from the base of the sealing tube 41; a pressure-supplying block 233, which is located between the second water inlet hole 213 and the rotating hole 13 and connected to the water inlet square tube 21; a second fixing ring 234, one side of which is fixedly connected to the pressure-supplying block 2 33 is fixedly connected to a side close to the second water inlet hole 213, and the second fixing ring is connected to the first fixing ring 232 through a spring 235; a threaded rod 236 is passed through the rotating hole 13, and one end of the threaded rod 236 is connected to a side of the pressure block 233 close to the rotating hole 13; a limiting ring 237 is located on the outer wall of the water storage tank body 1 and cooperates with the rotating hole 13; a rotating tube 238 is sleeved on one end of the threaded rod 236 extending out of the water storage tank body 1 and connected to the limiting ring 237; a rotating wrench 239 is connected to the outer wall of the rotating tube 238.

[0061] In the embodiment of the utility model, the pressure block 231 is a rectangular block, the thickness of which is slightly larger than the width of the second water inlet hole 213, and a rubber sealing square ring is fixedly connected to the side close to the rotating hole 13; the outer wall of the rubber sealing square ring fits the inner wall of the water inlet square tube 21, and one end is fixedly connected to the pressure block 231; the two sides of the pressure block 233 are respectively fixedly connected with rubber sealing square rings, and the outer walls of the rubber sealing square rings fit the inner wall of the water inlet square tube 21, and one end is fixedly connected to the pressure block 231; in actual installation and use, first turn the rotating wrench 239 clockwise to drive the rotating tube 238 to rotate on the limiting ring 237, and then drive The movable threaded rod 236 moves downward, thereby driving the pressure-supplying block 233 to move along the water inlet square tube 21 toward the pressure-receiving block 231, thereby compressing the spring 235. Then, when the device enters the water, the water flows into the water inlet square tube 21, and is affected by the water pressure, thereby causing the pressure-receiving block 231 to move along the water inlet square tube 21 toward the pressure-supplying block 233. Finally, when the pressure-receiving block 231 moves along the water inlet square tube 21 toward the pressure-supplying block 233, the second water inlet hole 213 blocked by the pressure block 231 communicates with the water flow in the water inlet square tube 21, thereby causing the water flow in the water inlet square tube 21 to enter the water storage area of ​​the water storage tank 1 through the second water inlet hole 213.

[0062] like Figures 1 to 8 As shown, the water outlet assembly 3 includes: a water outlet pipe 31 , one end of which is passed through the water outlet hole 12 and connected to the water storage box 1 ; and a first threaded cover 32 , which is sleeved on the other end of the water outlet pipe 31 .

[0063] In the embodiment of the utility model, the water outlet pipe 31 is provided with threads; in practical application, the first threaded cover 32 is rotated along the threads on the water outlet pipe 31 to seal the water outlet pipe 31 to prevent water leakage or water ingress.

[0064] like Figures 1 to 8 As shown, the sealing assembly 4 includes: a sealing tube 41, which is sleeved on the outside of the rotating tube 238 and connected to the water storage tank body 1; and a second threaded cover 42, which is sleeved on the other end of the sealing tube 41 and connected.

[0065] In the embodiment of the utility model, the outer wall of the sealing tube 41 is provided with threads; in actual use, by rotating the second threaded cover 42 along the threads on the sealing tube 41 to abut against the water storage tank body 1, the controllable water inlet component 2 extending out of the water storage tank body 1 can be sealed to prevent water from entering.

[0066] In a specific embodiment: first, the first fixing ring 232 is fixed on the pressure block 231, and then one end of the spring 235 is inserted into the first fixing ring 232 and fixedly connected to the pressure block 231, and then the second fixing ring 234 is fixed to the pressure block 233, and then the second fixing ring 234 is sleeved on the other end of the spring 235, so that one end of the threaded rod 236 is fixedly connected to the other side of the pressure block 233; further, the already connected pressure block 231 and the pressure block 233 are moved along the water inlet square tube 21 toward the base of the sealing tube 41 with the pressure block 231 as the first, until the sealing rubber ring 2311 on the pressure block 231 fits with the sealing groove 2121 of the base of the sealing tube 41, and then a part of the threaded rod 236, the pressure block 233 and the pressure block 231 are installed into the water inlet square tube 21.

[0067] Secondly, the installed water inlet square tube 21 is inserted into the water storage tank body 1 through the first water inlet hole 11, starting with the end of the threaded rod 236 extending out of the water inlet square tube 21, and the end of the threaded rod 236 extending out of the water storage tank body 1 through the rotating hole 13, and then the water inlet square tube 21 is fixedly sealed and connected to the water storage tank body 1 at the connection, and the water inlet conical square tube 22 is fixedly connected to the end of the water inlet square tube 21 extending out of the water storage tank body 1 through the first water inlet hole 11; further, the sleeve Insert the end of the threaded rod 236 that extends out of the water tank body 1, and move downward along the threaded rod 236 until it is fixedly connected to the water tank body 1, then put the rotating tube 238 on the end of the threaded rod 236 that extends out of the water tank body 1 and clamp it together with the limiting ring 237, and then fix the rotating wrench 239 to the outer wall of the rotating tube 238, and at the same time fix the outer wall of the water outlet pipe 31 to the water outlet hole 12, and install the sealing tube 41 on the outside of the rotating tube 238 and fix it to the water tank body 1, and the installation is completed.

[0068] Finally, the staff first rotates the rotating wrench 239 clockwise to drive the rotating tube 238 to rotate on the limiting ring 237, thereby driving the threaded rod 236 to move downward, and then driving the pressure-supplying block 233 to move along the water inlet square tube 21 toward the pressure-receiving block 231. At this time, since the sealing tube base 212 limits the top of the pressure-receiving block 231, the spring 235 between the pressure-receiving block 231 and the pressure-supplying block 233 can be compressed, thereby cooperating with the water pressure at different depths, so that when the water pressure is greater than the spring supporting force between the pressure-receiving block 231 and the pressure-supplying block 233, the pressure-receiving block 231 can move downward to leak out of the second water inlet hole 213; based on this, the staff next rotates the second threaded cover 42, so that the second threaded cover 42 moves downward along the sealing tube 41 and contacts the water storage tank body 1. Then, the controllable water inlet component 2 can be extended out of one side of the water storage tank 1 and sealed, thereby preventing the water inflow from affecting the air pressure in the water storage tank, resulting in the inability to accurately collect water samples at the required depth; then, the set device is placed in the water along the rope or tube, and the water flows into the water inlet square tube 21. When it reaches the triggering water pressure layer, it is affected by the water pressure, and the pressure block 231 moves along the water inlet square tube 21 toward the pressure supply block 233. Finally, when the pressure block 231 moves along the water inlet square tube 21 toward the pressure supply block 233, the second water inlet hole 213 blocked by the pressure block 231 communicates with the water flow in the water inlet square tube 21, so that the water flow in the water inlet square tube 21 enters the water storage area of ​​the water storage tank 1 through the second water inlet hole 213, thereby realizing accurate collection of the target water sample layer.

[0069] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
