[0002] With the widespread application of deep well pumps in various fields, the performance requirements for their water outlet structures are becoming increasingly higher. In actual use, on the one hand, it is necessary to ensure that the deep well pump can stably discharge water when working, and when the pump stops working, it can prevent water backflow and leakage through good sealing performance to ensure the stability and reliability of the deep well pump. At the same time, in order to facilitate the maintenance of the equipment, the water outlet structure should have a convenient installation and disassembly method to reduce maintenance costs and time. At present, some existing deep well pump water outlet structures often have some deficiencies in actual applications. For example, when the pump stops working, the sealing effect is relatively poor, which easily leads to water backflow and leakage. Moreover, during maintenance, the disassembly and installation process is relatively complicated, which increases the difficulty and cost of maintenance. Utility Model Content

[0021] The slide groove 22 is arranged in a circular array along the axial center point of the sleeve 21. The outer wall of the slide rod 23 is slidably connected to the inner wall of the sleeve 21. The outer wall of the tension spring 26 away from the pull plate 25 is fixedly connected to the outer wall of the sleeve 21. When the pull plate 25 is pulled, the pull plate 25 drives the clamping block 24 to slide outward in the slide groove 22 through the slide rod 23. When the plate 25 is pulled, the tension spring 26 contracts, which can drive the pull plate 25, the slide rod 23 and the clamping block 24 to reset. The outer wall of the extrusion spring 283 away from the plug plate 282 is fixedly connected to the outer wall below the support plate 27.

[0022] The water inlet structure 1 includes a water inlet pipe 11, the inner wall below the water inlet pipe 11 is fixedly connected to a rubber ring 12, the outer wall below the rubber ring 12 is fixedly connected to a threaded pipe 13, the side wall of the water inlet pipe 11 is provided with a clamping groove 14, the outer wall above the water inlet pipe 11 is fixedly connected to a limiting ring 15, and the inner wall of the limiting ring 15 is fixedly connected to a sealing ring 16.

[0023] The outer wall below the sealing ring 16 is fixedly connected to the outer wall above the water inlet pipe 11 , and the clamping grooves 14 are arranged in a circular array along the axis of the water inlet pipe 11 .

[0024] The inner wall below the sleeve 21 is slidably connected to the outer wall of the water inlet pipe 11, the outer wall below the sealing gasket 211 contacts the outer wall above the water inlet pipe 11, the outer wall of the plug plate 282 is slidably connected to the inner wall of the water inlet pipe 11, the outer wall below the plug plate 282 contacts the outer wall above the sealing ring 16, and the outer wall of the clamping block 24 is slidably connected to the inner wall of the clamping groove 14. When the plug plate 282 is pushed upward, the extrusion spring 283 is compressed and stored. At the same time, the plug plate 282 separates from the sealing ring 16 along the limiting ring 15 and moves upward. The plug plate 282 slides upward in the support plate 27 through the support rod 28, so that the water inlet pipe 11 is connected to the inside of the sleeve 21. On the contrary, the extrusion spring 283 above the plug plate 282 is in a released state, exerting downward pressure on the plug plate 282, so that the plug plate 282 is in close contact with the sealing ring 16 to ensure sealing performance.

[0025] Working principle: First, thread the threaded tube 13 onto the pump port to connect the device to the pump, then start the pump, and the pumped water will flow from the pump port along the rubber ring 12 on the threaded tube 13 into the water inlet pipe 11. Since the plug plate 282 is in close contact with the inner wall of the water inlet pipe 11 through the extrusion spring 283, the water pressure will act on the plug plate 282. As the pump works, the water pressure increases, and the upward thrust of the water on the plug plate 282 overcomes the pressure of the extrusion spring 283, pushing the plug plate 282 to separate from the limit ring 15 and the sealing ring 16 and move upward. The plug plate 282 passes through The support rod 28 slides upward in the support plate 27, opening the water flow channel, and the extrusion spring 283 is also compressed and stored. At this time, water enters the interior of the sleeve 21 and flows out through the water outlet joint 29 on the outer wall above the sleeve 21, realizing the water outlet function of the deep well pump. When the pump stops working, the extrusion spring 283 above the plug plate 282 is not affected by the water pressure and returns to the elastic state, exerting downward pressure on the plug plate 282, so that the plug plate 282 is in close contact with the sealing ring 16 to ensure the sealing performance. The limit plate 281 above the support rod 28 prevents the support rod 28 from falling off the support plate 27.

[0026] When it is necessary to disassemble the water outlet device 2, pull the pull plate 25, and the pull plate 25 drives the clamping block 24 to slide outward in the slide groove 22 through the slide rod 23, so that the clamping block 24 slides out of the clamping groove 14 on the side wall of the water inlet pipe 11. At this time, the water outlet device 2 can be removed from the water inlet structure 1, which is convenient for internal maintenance. The tension spring 26 is stretched during the disassembly process. When the pull plate 25 is released, the tension spring 26 contracts, driving the pull plate 25, the slide rod 23 and the clamping block 24 to reset. Conversely, when the water outlet device 2 is installed again, the sleeve 21 is put on the outer wall of the water inlet pipe 11, and Press from top to bottom so that the clamping block 24 contacts the outer wall of the top of the water inlet pipe 11, and continue pressing to make the clamping block 24 slide outward along the slide groove 22 through the inclined surface of the clamping block 24, and at the same time drive the slide rod 23 to slide outward along the inner wall of the sleeve 21, and the tension spring 26 is stretched and stored. When the sealing gasket 211 contacts the outer wall above the water inlet pipe 11, the clamping block 24 also corresponds to the clamping groove 14 on the side wall of the water inlet pipe 11, and the tension spring 26 releases the elastic force to slide the slide rod 23 and drive the clamping block 24 to slide into the clamping groove 14, thereby realizing the connection and fixation between the water outlet device 2 and the water inlet structure 1.
