Description

Technical Field

[0001] This invention relates to the field of wellpoint dewatering, and more specifically to an energy-saving pneumatic tubular wellpoint dewatering device. Background Technology

[0002] Lightweight well points are a method of artificially lowering the groundwater level. They involve sinking a thin-diameter well pipe into an aquifer deeper than the foundation along the perimeter or one side of the foundation pit. The upper part of the well pipe is connected to a main pipe, and groundwater is continuously pumped out from the well pipe through the main pipe using pumping equipment, thereby lowering the original groundwater level below the foundation.

[0003] Existing dewatering devices generally achieve dewatering by pumping water. However, even after filtration, some impurities still enter the pump during pumping, affecting its operation. Furthermore, the pumping control of water level reduction is not precise enough. To address this, we propose an energy-saving pneumatic well point dewatering device. Summary of the Invention

[0004] The main technical problem solved by this invention is to provide an energy-saving pneumatic well point dewatering device, which can solve the problem that even after filtration, some impurities still enter the water pump during pumping, affecting the pump, and that the water level control of the pump is not precise enough.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, more specifically, an energy-saving pneumatic well point dewatering device includes an air pump, a connecting mechanism, a docking mechanism, a sealing mechanism, and drainage pipes. The connecting mechanism is fixedly installed at the output end of the air pump, and the docking mechanism is fixedly connected at the end of the connecting mechanism away from the air pump. The sealing mechanism is fixedly installed on the outer wall of the docking mechanism. There are two drainage pipes, and both drainage pipes are slidably connected to the sealing mechanism.

[0006] Furthermore, the communication mechanism includes a pneumatic pipe, a stop block, a piston cylinder, a movable plate, a sealing block, and a spring. Two stop blocks are integrally formed inside the pneumatic pipe. The piston cylinder is slidably connected to the pneumatic pipe below the stop blocks. The piston cylinder is a hollow cylindrical structure with an open upper surface. A through-type connection port is formed on the lower surface of the piston cylinder. Symmetrical contraction cavities are formed inside the piston cylinder. The movable plate is slidably connected to the contraction cavity. The sealing block is fixedly connected to the opposite sides of the two movable plates inside the connection port. The spring is fixedly connected between the movable plate and the contraction cavity.

[0007] Furthermore, the docking mechanism includes an inflation tube, a connecting tube, a wedge-shaped shielding sleeve, a fixing block, and a second spring. The top of the inflation tube is fixedly connected to the bottom of the air pressure tube. The top of the inflation tube is fixedly connected to the connecting tube inside the air pressure tube. The bottom end of the connecting tube extends to the inside of the inflation tube. The outer wall of the connecting tube is symmetrically provided with exhaust holes inside the inflation tube. The outer wall of the connecting tube is symmetrically provided with air inlets inside the air pressure tube. The outer wall of the connecting tube is slidably connected to the wedge-shaped shielding sleeve inside the air pressure tube. The inner side of the wedge-shaped shielding sleeve is symmetrically provided with vertical grooves. The outer wall of the connecting tube is fixedly connected to the inner side of each of the two vertical grooves. The second spring is fixedly connected between the fixing block and the vertical groove.

[0008] Furthermore, the outer wall of the wedge-shaped shielding sleeve is provided with multiple airflow grooves.

[0009] Furthermore, the sealing mechanism includes an I-shaped disc, an elastic airbag, a connecting tube, and a spring. The elastic airbag is fixedly connected to the outer wall of the I-shaped disc, and the connecting tube is fixedly connected to the upper surface of the elastic airbag. The end of the connecting tube away from the elastic airbag passes through the upper surface of the I-shaped disc and is fixedly connected to the lower part of the outer wall of the air pressure tube. The spring is fixedly connected to the inside of the elastic airbag.

[0010] Furthermore, the upper surface of the I-shaped disc has two through-holes integrally formed, which are slidably connected to the drain pipe. The inner sidewalls of the two holes are provided with recesses at opposite ends. The inner sides of the two recesses are integrally formed with air cavities. The air cavities are fixedly connected to the elastic airbag by an air groove. A movable plug is slidably connected inside the air cavity. The side of the movable plug away from the air groove is fixedly connected to a stop block inside the recess. A round rod is fixedly connected inside the recess. The outer sidewall of the round rod is rotatably connected to a gear via a rotating shaft.

[0011] Furthermore, both drainage pipes have toothed grooves on their opposite sides, which mesh with the gear.

[0012] Furthermore, the bottom ends of the two drain pipes are fixedly connected to a filter cylinder, and the outer wall of the filter cylinder is integrally formed with multiple filter holes.

[0013] Furthermore, the input end of the air pump is fixedly connected to an air inlet pipe, and a filter screen is installed on the left end of the air inlet pipe by means of bolts.

[0014] The beneficial effects of the energy-saving pneumatic wellpoint dewatering device of the present invention are as follows:

[0015] When using this invention, the sealing mechanism seals the inside of the pipe well, and the drain pipe slides down along the sealing mechanism until it contacts the water surface. Then it continues to slide down, and the distance between the water surface and the bottom of the drain pipe is the drainage range. The air pump is started to pump air, and the air is injected and squeezed into the pipe well through the connecting mechanism and the docking mechanism, so that the water inside the pipe well is discharged through the drain pipe, achieving the drainage effect. This invention can effectively avoid the problem of water pumps being easily blocked and damaged by mud and other materials when pumping water, and it can also precisely control the water level.

[0016] In this invention, the air pressure pipe, baffle, piston cylinder, movable plate, sealing block, and spring 1 that make up the connecting mechanism, through the set contraction chamber and the interface, allow the air pump to start. When the air is filled into the air pressure pipe, it will first drive the piston cylinder below the baffle to slide down. The movable plate, sealing block, and spring 1 keep the piston cylinder in a sealed state, thereby ensuring that it will drop when subjected to air pressure impact. When the sealing block contracts, the piston cylinder is in a ventilated state.

[0017] In this invention, the air inlet pipe, connecting pipe, wedge-shaped shielding sleeve, fixing block, and spring 2 that make up the docking mechanism utilize the exhaust port, air inlet port, and vertical groove to allow the piston cylinder to descend to a certain position, which will push the wedge-shaped shielding sleeve to slide down along the vertical groove. This will cause the top of the connecting pipe to push the two sealing blocks to contract towards the inside of the contraction chamber. At this time, the air inlet port is in the open state, so the air pressure injected by the air pump will enter through the air inlet port and be discharged through the exhaust port, thereby inflating the well into the pipe through the air inlet pipe.

[0018] In this invention, the sealing mechanism consists of an I-shaped disc, an elastic air bladder, a connecting pipe, and a spring. When the air pump is started and the impact piston cylinder descends, the air pressure below the piston cylinder is filled into the elastic air bladder, causing the elastic air bladder to expand. Thus, after the I-shaped disc extends into the well, the elastic air bladder will keep the well and the I-shaped disc in a sealed state.

[0019] The present invention uses a circular hole, a notch, an air chamber, an air groove, a movable plug, a stop block, and a circular rod to start the air pump, lower the piston cylinder, and fill the air chamber with the internal air pressure of the piston cylinder through the air groove, which pushes the movable plug to move, thereby causing the stop block to move towards the gear, stop the gear, and restrict the rotation of the gear.

Detailed Implementation

[0029] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0030] According to one aspect of the invention, such as Figure 1-7 The present invention provides an energy-saving pneumatic well point dewatering device, including an air pump 1, a connecting mechanism 2, a docking mechanism 3, a sealing mechanism 4, and a drain pipe 5. The output end of the air pump 1 is fixedly installed with the connecting mechanism 2, and the end of the connecting mechanism 2 away from the air pump 1 is fixedly connected to the docking mechanism 3. The outer wall of the docking mechanism 3 is fixedly installed with the sealing mechanism 4. There are two drain pipes 5, and both drain pipes 5 are slidably connected to the sealing mechanism 4.

[0031] In this embodiment, the connecting mechanism 2 includes a pneumatic pipe 201, a stop block 202, a piston cylinder 203, a movable plate 204, a sealing block 205, and a spring 206. Two stop blocks 202 are integrally formed inside the pneumatic pipe 201. The piston cylinder 203 is slidably connected to the pneumatic pipe 201 below the stop blocks 202. The piston cylinder 203 is a hollow cylindrical structure with an open upper surface. A through-type connection port 6 is formed on the lower surface of the piston cylinder 203. Symmetrical contraction chambers 7 are formed inside the piston cylinder 203. Movable plates 204 are slidably connected inside the contraction chambers 7. Sealing blocks are fixedly connected to the opposite sides of the two movable plates 204 inside the connection port 6. 205. A spring 206 is fixedly connected between the movable plate 204 and the contraction chamber 7. In this invention, the air pressure pipe 201, the stop block 202, the piston cylinder 203, the movable plate 204, the sealing block 205, and the spring 206 that make up the communication mechanism 2, through the contraction chamber 7 and the interface 6, allow the air pump 1 to start. After the air is filled into the air pressure pipe 201, it will first drive the piston cylinder 203 below the stop block 202 to slide down. The movable plate 204, the sealing block 205, and the spring 206 keep the piston cylinder 203 in a sealed state, thereby ensuring that it will drop when subjected to air pressure impact. When the sealing block 205 contracts, the piston cylinder 203 is in a ventilated state.

[0032] In this embodiment, the docking mechanism 3 includes an inflation tube 301, a docking tube 302, a wedge-shaped shielding sleeve 303, a fixing block 304, and a spring 305. The top of the inflation tube 301 is fixedly connected to the bottom of the air pressure tube 201. The top of the inflation tube 301 is located inside the air pressure tube 201 and is fixedly connected to the docking tube 302. The bottom end of the docking tube 302 extends to the inside of the inflation tube 301. The outer wall of the docking tube 302 is symmetrically provided with exhaust holes 8 inside the inflation tube 301. The outer wall of the docking tube 302 is symmetrically provided with air inlets 9 inside the air pressure tube 201. The outer wall of the docking tube 302 is slidably connected to the wedge-shaped shielding sleeve 303 inside the air pressure tube 201. The inner side of the wedge-shaped shielding sleeve 303 is symmetrically provided with vertical grooves 10. The docking tube 302... The outer side wall is fixedly connected to the inner side of the two vertical grooves 10 with fixing blocks 304. The fixing blocks 304 and the vertical grooves 10 are fixedly connected with springs 305. The air filling pipe 301, the connecting pipe 302, the wedge-shaped shielding sleeve 303, the fixing blocks 304 and the springs 305 that make up the docking mechanism 3 in this invention utilize the exhaust hole 8, the air inlet hole 9 and the vertical grooves 10 so that after the piston cylinder 203 descends to a certain position, it will push the wedge-shaped shielding sleeve 303 to slide down along the vertical grooves 10, so that the top of the connecting pipe 302 will push the two sealing blocks 205 to contract towards the inside of the contraction chamber 7. At this time, the air inlet hole 9 is in the open state, so the air pressure injected by the air pump 1 will enter through the air inlet hole 9 and be discharged through the exhaust hole 8, thereby inflating the well into the pipe through the air filling pipe 301.

[0033] In this embodiment, the outer wall of the wedge-shaped shield sleeve 303 is provided with multiple airflow grooves 11 to prevent the air pressure when the piston cylinder 203 descends from causing the wedge-shaped shield sleeve 303 to descend, thereby preventing the air inlet 9 from lifting up for air intake.

[0034] In this embodiment, the sealing mechanism 4 includes an I-shaped disc 401, an elastic airbag 402, a connecting pipe 403, and a spring 404. The elastic airbag 402 is fixedly connected to the outer wall of the I-shaped disc 401, and the connecting pipe 403 is fixedly connected to the upper surface of the elastic airbag 402. One end of the connecting pipe 403 away from the elastic airbag 402 passes through the upper surface of the I-shaped disc 401 and is fixedly connected to the lower part of the outer wall of the air pressure pipe 201. The interior of the elastic airbag 402 is fixedly connected to... With spring 404 attached, the H-shaped disc 401, elastic airbag 402, connecting pipe 403, and spring 404 that make up the sealing mechanism 4 in this invention cause the air pump 1 to start. When the impact piston cylinder 203 descends, the air pressure below the piston cylinder 203 will be filled into the elastic airbag 402, causing the elastic airbag 402 to expand. Thus, after the H-shaped disc 401 extends into the well, the elastic airbag 402 will make the well and the H-shaped disc 401 be in a sealed state.

[0035] In this embodiment, the upper surface of the I-shaped disc 401 has two through-holes 12 integrally formed. The holes 12 are slidably connected to the drain pipe 5. The inner sidewalls of the two holes 12 are provided with recesses 13 at opposite ends. The inner sides of the two recesses 13 are integrally formed with air cavities 14. The air cavities 14 are fixedly connected to the elastic airbag 402 by air grooves 15. A movable plug 16 is slidably connected inside the air cavity 14. The side of the movable plug 16 away from the air groove 15 is fixedly connected to a stop block 17 inside the recess 13. A round rod 18 is fixedly connected inside the recess 13. A gear 19 is rotatably connected to the outer wall of the round rod 18 via a rotating shaft. The present invention, through the round hole 12, recess 13, air chamber 14, air groove 15, moving plug 16, stop block 17 and round rod 18, enables the air pump 1 to start, the piston cylinder 203 to descend, and the air pressure inside the piston cylinder 203 to be filled into the air chamber 14 through the air groove 15, pushing the moving plug 16 to move, thereby causing the stop block 17 to move towards the gear 19, stop the gear 19, and restrict the rotation of the gear 19.

[0036] In this embodiment, the two drain pipes 5 are provided with toothed grooves 20 on opposite sides. The toothed grooves 20 are meshed with the gear 19, so that the drain pipes 5 can slowly slide down through the meshing of the toothed grooves 20 and the gear 19, making it more convenient to adjust the depth of the drain pipes into the water.

[0037] In this embodiment, the bottom ends of the two drain pipes 5 are fixedly connected to a filter cylinder 21. The outer wall of the filter cylinder 21 is integrally formed with multiple filter holes 22, which play a filtering role and prevent debris inside the well water from clogging the drain pipes 5.

[0038] In this embodiment, the input end of the air pump 1 is fixedly connected to the air inlet pipe 23, and the left end of the air inlet pipe 23 is installed with a filter screen 24 by bolts to filter dust in the air and prevent it from being sucked into the air pump 1.

[0039] The working principle of this device is as follows: When using this invention, the sealing mechanism 4 seals the inside of the pipe well, and the drain pipe 5 slides down along the sealing mechanism 4. After it contacts the water surface, it continues to slide down. The distance between the water surface and the bottom of the drain pipe 5 is the drainage range. The air pump 1 is started to draw air, which is then injected into the pipe well through the connecting mechanism 2 and the docking mechanism 3. This causes the water inside the pipe well to be discharged through the drain pipe 5, achieving the drainage effect. It can also effectively avoid the problem of water pumps being easily blocked and damaged by mud and other materials when pumping water, and can precisely control the water level.
