[0002] A water-stopping device is a specialized device used to separate aquifers at different depths within a borehole. It achieves stratified water stoppage through mechanical sealing or material filling, ensuring independent sampling or pumping tests of water quality and level at different aquifers. The water-stopping device consists of a sleeve, an air bladder, an air nozzle, an air pipe, a collection pipe, and a connector for an external water pipe. When using the water-stopping device, the collection pipe and sleeve are connected by threads. Then, the air nozzles on the two sleeves are connected to the air pipe, and the device is placed into the borehole for hydrogeological drilling. Air is then pumped into the air pipe using an air pump, causing the air bladder to inflate and extend into the borehole, thereby separating aquifers at different depths within the borehole. Finally, a self-priming pump is connected to the water pipe and started to extract water from the collection pipe.

[0003] The inventors discovered in their daily work that when using the water-stopping device, because the connector is located inside the collection pipe, the tools used by workers, such as wrenches, cannot be properly inserted into the collection pipe when fixing the water pipe and connector, which may make fixing the water pipe and connector more troublesome.

[0006] The effect achieved by the above components is as follows: by setting up a disassembly assembly, when it is necessary to fix the water pipe and connector, the disassembly mechanism can be used to remove the mounting block from the mounting port, then the water pipe can be inserted into the connector, and then the water pipe and connector can be fixed from the mounting port using a screwing tool, thereby facilitating the fixing of the water pipe and connector as much as possible.

[0007] Preferably, circular pins are slidably inserted at both ends of the mounting block, and positioning grooves are provided on both sides of the inner wall of the mounting port.

[0008] The effect achieved by the above components is that the circular pin is completely separated from the positioning groove by the pulling mechanism, so that it is retracted into the mounting block.

[0009] Preferably, a spring is fixedly connected between the two circular pins, and a sealing ring is provided between the mounting port and the mounting block.

[0010] The effect achieved by the above components is that the circular pin is completely separated from the positioning groove by the pulling mechanism, so that it is retracted into the mounting block and the spring is compressed.

[0011] Preferably, one end of the circular pin is fixedly connected to a pull rope, which passes through the mounting block.

[0012] The effect achieved by the above components is that pulling the pull rope completely separates the circular pin from the positioning groove, causing it to retract into the mounting block.

[0013] Preferably, a first magnetic sheet is fixedly connected to the upper end of the circular pin, and a second magnetic sheet is fixedly connected to the inner wall of the positioning groove. The first magnetic sheet and the second magnetic sheet attract each other when they are close to each other.

[0014] The effect achieved by the above components is that by setting the first magnetic plate and the second magnetic plate, the circular pin is limited by the auxiliary device.

[0015] Preferably, the arc surface of the collection tube is provided with a filter assembly, the filter assembly including a filter cover disposed on the arc surface of the collection tube, and a sealing gasket is disposed between the filter cover and the collection tube.

[0016] The effect achieved by the above components is to filter the groundwater drawn into the connector by setting up a filter cover and a sealing gasket.

[0017] Preferably, a threaded rod is fixedly connected to the upper end of the filter cover, and a retaining ring is fixedly connected to the arc surface of the collection tube.

[0018] The effect achieved by the above components is to insert the threaded rod into the retaining ring, and then use the fixing mechanism to fix it, thereby fixing the filter cover.

[0019] Preferably, the threaded rod passes through the fixing ring, and a nut is threadedly connected to the arc surface of the threaded rod.

[0020] The effect achieved by the above components is to insert the threaded rod into the retaining ring and then secure it with a nut.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting up a disassembly component, when it is necessary to fix the water pipe and connector, the disassembly mechanism can remove the mounting block from the mounting port, then insert the water pipe into the connector, and then use a screwing tool to fix the water pipe and connector from the mounting port. This achieves the effect of facilitating the fixing of the water pipe and connector as much as possible, and solves the problem that when fixing the water pipe and connector, the wrench and other tools used by workers cannot be properly inserted into the collection tube because the connector is located inside the collection tube, which may make fixing the water pipe and connector more troublesome.

Next, connect and start the self-priming pump to the water pipe 9 to extract the water from the collection pipe 5. When it is necessary to fix the water pipe 9 and the connector 8, pull the pull rope 28 to completely separate the circular pin 23 from the positioning groove 24, causing it to retract into the mounting block 22, thus releasing the spring. Spring 27 is compressed, and mounting block 22 is removed from mounting port 21. Then, water pipe 9 is inserted into connector 8. Then, a screwing tool is used to fix water pipe 9 and connector 8 from mounting port 21, thereby facilitating the fixation of water pipe 9 and connector 8 as much as possible. By setting first magnetic plate 25 and second magnetic plate 26, the auxiliary limit of circular pin 23 is achieved. By setting filter cover 31 and sealing gasket 35, the groundwater sucked into connector 8 is filtered.
