Description
Technical Field
[0001] This invention relates to the field of gate pump sealing technology, specifically a sealing structure for a pollution prevention gate pump. Background Technology
[0002] Pollution control gate pumps are key pieces of equipment used in water conservancy projects and sewage treatment. They are primarily used to control water flow and prevent the spread of sewage and pollutants. Through the coordinated operation of the gate opening and closing and the pump body, they achieve precise control of water flow, effectively preventing sewage overflow and pollution spread, ensuring the safety of the aquatic environment, and playing a vital role in maintaining ecological balance and the rational use of water resources.
[0003] When the anti-pollution gate pump is running, the connection between the gate and the pump body will generate high-frequency micro-vibrations due to the impact of water flow. These high-frequency micro-vibrations can easily cause gaps between the seals and components, leading to liquid leakage. At the same time, they can accelerate the fatigue wear of the seals and shorten their service life. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is as follows: A sealing structure for a pollution prevention gate pump, comprising a pump base, symmetrically arranged support frames on the top of the pump base, a pump pipe fixedly connected to the top of the support frames, a spiral fan arranged inside the pump pipe, a main rotating shaft fixedly connected to the outer surface of the spiral fan, an energy-saving generator arranged at the end of the main rotating shaft away from the spiral fan, and a support platform arranged at the bottom of the energy-saving generator, further comprising:
[0005] A sealing block unit is installed at the bend of the pump pipe to ensure the sealing of the connection between the main shaft and the pump pipe, and a gate unit is installed on the top of the pump base to control the flow of the medium in the pump pipe.
[0006] The gate unit includes a gate frame, a hydraulic device is fixedly connected to the gate frame, a telescopic rod is provided at the bottom of the hydraulic device, the output end of the telescopic rod is fixedly connected to the gate main board, a water-facing layer is provided on the outer surface of the gate main board, a flexible rubber buffer pad is provided inside the water-facing layer, a corrugated metal spring is provided between the flexible rubber buffer pad and the gate main board, the corrugated metal spring has good elastic deformation ability and can effectively absorb the high-frequency micro vibrations of the gate caused by water flow impact, a sealing mechanism is provided on the inner wall of the gate main board, and a pressurizing mechanism is provided on the side of the sealing mechanism near the pump pipe;
[0007] A rubidium magnet ring is also provided at one end of the pump pipe near the gate unit.
[0008] Preferably, the sealing mechanism includes a guide telescopic rod that controls only the telescopic direction. One end of the guide telescopic rod is fixedly connected to an extension layer. The radius of the extension layer is slightly larger than the radius of the pump pipe port. A telescopic spring is symmetrically arranged on the inner wall of the gate main plate. One end of the telescopic spring is fixedly connected to the outer surface of the extension layer. A controller equipped with a power supply is fixedly connected to the outer surface of the extension layer. The controller is connected to a power control component via a wire. A neodymium magnet plate is fixedly connected to the outer surface of the extension layer. An energized coil is arranged on the neodymium magnet plate. The energized coil is controlled by the power control component.
[0009] Preferably, the bottom of the gate frame is fixedly connected to the top of the pump base, and the outer surface of the guide telescopic rod is fixedly connected to the inner wall of the gate main plate;
[0010] Under normal conditions, the attraction between the rubidium magnet ring and the rubidium magnet plate is less than the elastic force of the first telescopic spring. When the controller energizes the coil through the power supply, the magnetic field generated by the coil will interact with the inherent magnetic field of the rubidium magnet plate. At this time, by changing the magnitude and direction of the current in the coil, the strength and direction of the overall magnetic field can be adjusted, so that the attraction between the rubidium magnet ring and the rubidium magnet plate is greater than the elastic force of the first telescopic spring.
[0011] Preferably, the pressurizing mechanism includes a protruding layer disposed on the outer surface of the protruding layer, the radius of the protruding layer being the same as the radius of the pump pipe port, a plastic waterproof material being fixedly connected to the outer ring of the protruding layer, and humidity sensors capable of detecting water leakage being uniformly disposed on the outer surface of the protruding layer, a built-in energy-saving motor being fixedly connected to the center of the inner wall of the protruding layer, a rotating arm being fixedly connected to the output end of the built-in energy-saving motor, a support column being fixedly connected to the inner wall of the rotating arm, and a second telescopic spring being disposed on the inner wall of the rotating arm, a moving block being fixedly connected to one end of the second telescopic spring, and a pressing roller being fixedly connected to the end of the moving block away from the second telescopic spring.
[0012] Preferably, the outer surface of the protruding layer is fixedly connected to the side of the extended layer away from the guide telescopic rod, and the inner wall of the movable block is slidably connected to the outer surface of the support column.
[0013] Preferably, the sealing block unit includes a barrier block with side grooves symmetrically arranged at both ends, and a vibration sensor is fixedly connected to the top of the barrier block;
[0014] The sealing block unit also includes a support plate 1 symmetrically arranged on the top of the support platform. A hydraulic device 2 is fixed to the top of the support plate 1. The output end of the hydraulic device 2 is fixedly connected to the support plate 2. Insertion columns adapted to the side grooves are evenly arranged on the outer surface of the support plate 2.
[0015] Preferably, the barrier block is fixed to the bend in the pump pipe by bolts and welding, and the bottom of the support plate is fixedly connected to the top of the support frame.
[0016] Preferably, the sealing block unit further includes a water-blocking mechanism disposed on the barrier block inside the pump pipe. The water-blocking mechanism is used to protect the sealing of the connection between the main shaft and the pump pipe. The main shaft is provided with an inner groove near the water-blocking mechanism.
[0017] The outer surface of the main shaft is rotatably connected to the inner wall of the barrier block.
[0018] Preferably, the water-blocking mechanism includes a water-blocking ring, and four air pressure pipes are symmetrically arranged on the inner wall of the water-blocking ring. The end of the air pressure pipe facing the spiral fan is slidably connected to a push-in end, and a pressure plate is fixedly connected to the outer surface of the push-in end. The side of the air pressure pipe away from the push-in end is provided with a push-out end, and an insertion block is fixedly connected to the outer surface of the push-out end.
[0019] Preferably, one end of the water-proof ring is fixedly connected to the outer surface of the barrier block, and the size of the insertion block is adapted to the inner groove and can impede water flow.
[0020] The beneficial effects of this invention are as follows:
[0021] 1. This invention, by setting up a gate unit, sequentially sets up a flexible rubber buffer pad and a wave-shaped metal spring sheet with good elastic deformation ability in the water-facing layer, which can effectively absorb the high-frequency micro-vibrations generated by the impact of water flow on the gate. This buffers the high-frequency micro-vibrations generated by the impact of water flow and avoids the micro-vibrations affecting the sealing mechanism and pressurizing mechanism on the other side.
[0022] 2. By setting up a sealing mechanism, after the gate main board is connected to the port of the pump pipe, the controller will start working to energize the control components and the energizing coil. The magnetic field generated by the energizing coil will interact with the inherent magnetic field of the rubidium magnet. By controlling the magnitude and direction of the current, the magnetic force of the magnetic field is increased, so that the attraction between the rubidium magnet ring and the rubidium magnet plate is greater than the elastic force of the extension spring, thereby making the protruding layer tightly fit with the port of the pump pipe and making the pressurizing mechanism fit against the inner wall of the pump body port.
[0023] 3. This invention incorporates a pressurizing mechanism. A humidity sensor on the outer layer detects whether water flows out between the protruding layer, the waterproof material, and the inner wall of the pump pipe. When water flow is detected, the built-in energy-saving motor drives the rotating arm to rotate. The resulting centrifugal force stretches the telescopic springs outward and causes the moving block and pressing roller to contact the protruding layer. This allows the pressing roller to apply appropriate pressure to the protruding layer, ensuring that the seal always maintains a suitable pre-tightening force and adaptively compensating for changes in the sealing gap caused by vibration and wear.
[0024] 4. This invention improves sealing by setting a sealing block unit. Without this unit, the main shaft and the inner wall of the pump pipe would be connected in a rotating manner, resulting in gaps. The sealing performance is enhanced by the addition of a barrier block and a water-blocking mechanism. Additionally, a vibration sensor is installed. Since the water pressure at the bend in the pump pipe is higher than at the straight section, when the vibration sensor detects significant vibration, the hydraulic devices on both sides drive the support plate and the insertion column to move. This causes the insertion column to enter the side groove of the barrier block, forming a unified anti-detachment protection system that effectively resists the impact of strong water flow and vibration on the sealing structure.
[0025] 5. By setting up a water-blocking mechanism, the water flow will impact the pressure plate, thereby pushing the push end in the air pressure pipe, causing the push end and the insertion block to move and enter the inner groove of the main rotating shaft, forming a water-blocking gap. This increases the resistance of the water flow to the rotating connection between the main rotating shaft and the blocking block, and improves the sealing between the main rotating shaft and the blocking block.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
[0041] Example 1, using Figures 1-13 The sealing structure of a pollution prevention gate pump according to one embodiment of the present invention will be described as follows.
[0042] like Figures 1-3 As shown, the sealing structure of a pollution prevention gate pump of the present invention includes a pump base 1, a support frame 2 symmetrically arranged on the top of the pump base 1, a pump pipe 3 fixedly connected to the top of the support frame 2, a spiral fan 4 arranged inside the pump pipe 3, a main rotating shaft 5 fixedly connected to the outer surface of the spiral fan 4, an energy-saving generator 7 arranged at the end of the main rotating shaft 5 away from the spiral fan 4, a support platform 8 arranged at the bottom of the energy-saving generator, and further includes:
[0043] A sealing block unit 6 is installed at the bend of the pump pipe 3 to ensure the sealing of the connection between the main shaft 5 and the pump pipe 3, and a gate unit 9 is installed on the top of the pump base 1 to control the flow of the medium in the pump pipe 3.
[0044] When the present invention is in operation, the gate unit 9 controls the flow of water in the pump pipe 3 and ensures the sealing of the contact surface between the valve unit and the port of the pump pipe 3. At the same time, when the valve unit does not obstruct the flow of water, the sealing block unit 6 ensures the sealing of the connection between the main shaft 5 and the pump pipe 3.
[0045] like Figures 4-6 As shown, the gate unit 9 includes a gate frame 91, a hydraulic device 92 fixedly connected to the gate frame 91, a telescopic rod 93 at the bottom of the hydraulic device 92, a gate main board 94 fixedly connected to the output end of the telescopic rod 93, a water-facing layer 95 on the outer surface of the gate main board 94, a flexible rubber buffer pad 96 inside the water-facing layer 95, a corrugated metal spring sheet 97 between the flexible rubber buffer pad 96 and the gate main board 94, the corrugated metal spring sheet 97 has good elastic deformation ability and can effectively absorb the high-frequency micro vibrations generated by the water flow impact of the gate, a sealing mechanism 98 is provided on the inner wall of the gate main board 94, and a pressurizing mechanism 99 is provided on the side of the sealing mechanism 98 near the pump pipe 3;
[0046] A neodymium magnet ring 10 is also provided at one end of the pump pipe 3 near the gate unit 9.
[0047] When it is necessary to close the gate to impede the flow of water in the pump body, the hydraulic device 92 will drive the telescopic rod 93 to extend downward and drive the gate main plate 94 to connect with the port of the pump pipe 3. The connection between the gate and the pump body will generate high-frequency micro-vibrations due to the impact of water flow. High-frequency micro-vibrations can easily cause gaps between the seals and components, leading to liquid leakage. At the same time, it will accelerate the fatigue wear of the seals and shorten their service life. Therefore, a flexible rubber buffer pad 96 and a wave-shaped metal spring plate 97 with good elastic deformation ability are sequentially installed in the water-facing layer 95. This can effectively absorb the high-frequency micro-vibrations generated by the impact of water flow on the gate, buffer the high-frequency micro-vibrations generated by the impact of water flow, and avoid the micro-vibrations affecting the sealing mechanism 98 and the pressurizing mechanism 99 on the other side.
[0048] like Figures 7-8As shown, the sealing mechanism 98 includes a guide telescopic rod 981 that controls only the telescopic direction. One end of the guide telescopic rod 981 is fixedly connected to an extension layer 982. The radius of the extension layer 982 is slightly larger than the radius of the pump pipe 3 port. A telescopic spring 983 is symmetrically arranged on the inner wall of the gate main plate 94. One end of the telescopic spring 983 is fixedly connected to the outer surface of the extension layer 982. A controller 984 with a power supply 985 is fixedly connected to the outer surface of the extension layer 982. The controller 984 is connected to a power control component 987 through wires. A neodymium magnet plate 986 is fixedly connected to the outer surface of the extension layer 982. An energized coil 988 is arranged on the neodymium magnet plate 986. The energized coil 988 is controlled by the power control component 987.
[0049] The bottom of the gate frame 91 is fixedly connected to the top of the pump base 1, and the outer surface of the guide telescopic rod 981 is fixedly connected to the inner wall of the gate main plate 94.
[0050] Under normal conditions, the attraction between the rubidium magnet ring 10 and the rubidium magnet plate 986 is less than the elastic force of the telescopic spring 983. When the controller 984 energizes the energized coil 988 through the power supply 985, the magnetic field generated by the energized coil 988 will interact with the inherent magnetic field of the rubidium magnet plate 986. At this time, by changing the magnitude and direction of the current in the coil, the strength and direction of the overall magnetic field can be adjusted, so that the attraction between the rubidium magnet ring 10 and the rubidium magnet plate 986 is greater than the elastic force of the telescopic spring 983.
[0051] After the gate main board 94 is connected to the port of the pump pipe 3, the controller 984 will start to work, so that the power supply 985 energizes the control component 987 and the energizing coil 988. The magnetic field generated by the energizing coil 988 will interact with the inherent magnetic field of the rubidium magnet. By controlling the magnitude and direction of the current, the magnetic force of the magnetic field is increased, so that the attraction between the rubidium magnet ring 10 and the rubidium magnet plate 986 is greater than the elastic force of the extension spring 983, so that the protruding layer 982 is tightly attached to the port of the pump pipe 3, and the pressurizing mechanism 99 is attached to the inner wall at the pump body port.
[0052] like Figures 9-10As shown, the pressurizing mechanism 99 includes a protruding layer 991 disposed on the outer surface of the protruding layer 982. The radius of the protruding layer 991 is the same as the radius of the pump pipe 3 port. A plastic waterproof material 992 is fixedly connected to the outer ring of the protruding layer 991. A humidity sensor 993 that can detect whether there is water leakage is uniformly disposed on the outer surface of the protruding layer 991. A built-in energy-saving motor 994 is fixedly connected to the center of the inner wall of the protruding layer 991. A rotating arm 995 is fixedly connected to the output end of the built-in energy-saving motor 994. A support column 996 is fixedly connected to the inner wall of the rotating arm 995. A second telescopic spring 997 is also disposed on the inner wall of the rotating arm 995. A moving block 998 is fixedly connected to one end of the second telescopic spring 997. A pressing roller plate 999 is fixedly connected to the end of the moving block 998 away from the second telescopic spring 997.
[0053] After the sealing mechanism 98 is attached to the pump pipe 3, the protruding layer 991 and the water-proof material 992 will also be attached to the inner wall of the pump pipe 3, further enhancing the sealing effect. At the same time, the humidity sensor 993 on the outer layer will detect whether water flows out from between the protruding layer 991 and the water-proof material 992 and the inner wall of the pump pipe 3. When water is detected, the built-in energy-saving motor 994 will drive the rotating arm 995 to rotate. The centrifugal force generated will cause the telescopic spring 997 to stretch outward and drive the moving block 998 and the pressing roller plate 999 to contact the protruding layer 991, so that the pressing roller plate 999 presses the protruding layer 991 appropriately, so that the seal always maintains a suitable pre-tightening force and adaptively compensates for the changes in the sealing gap caused by vibration and wear.
[0054] The outer surface of the protruding layer 991 is fixedly connected to the side of the extended layer 982 away from the guide telescopic rod 981, and the inner wall of the moving block 998 is slidably connected to the outer surface of the support column 996.
[0055] The specific workflow is as follows:
[0056] During operation, hydraulic device 92 drives telescopic rod 93 to extend downwards, causing gate main plate 94 to connect with the port of pump pipe 3. Within the water-facing layer 95, a flexible rubber buffer pad 96 and a wave-shaped metal spring plate 97 with good elastic deformation capacity are sequentially installed to effectively absorb the high-frequency micro-vibrations generated by water flow impact. Simultaneously, controller 984 activates, power supply 985 energizes control component 987 and energizing coil 988. By controlling the magnitude and direction of the current, the magnetic force of the magnetic field is increased, causing the attraction between neodymium magnet ring 10 and neodymium magnet plate 986 to exceed the elastic force of telescopic spring 983, thus ensuring a tight fit between the extended layer 982 and the port of pump pipe 3. The pressurizing mechanism 99 is pressed against the inner wall of the pump body port, and the protruding layer 991 and the water-proof material 992 are also pressed against the inner wall of the pump pipe 3, further sealing the area. At the same time, the humidity sensor 993 on the outer layer will detect whether water flows out between the protruding layer 991 and the water-proof material 992 and the inner wall of the pump pipe 3. When water is detected, the built-in energy-saving motor 994 will drive the rotating arm 995 to rotate. The centrifugal force generated will cause the extension spring 997 to stretch outward and drive the moving block 998 and the pressing roller plate 999 to contact the protruding layer 991, so that the pressing roller plate 999 presses the protruding layer 991 appropriately, so that the seal always maintains a suitable pre-tightening force and adaptively compensates for the changes in the sealing gap caused by vibration and wear.
[0057] Example 2, using Figures 1-13 The sealing structure of a pollution prevention gate pump according to one embodiment of the present invention will be described as follows.
[0058] like Figures 11-12 As shown, the sealing structure of the anti-pollution gate pump of the present invention, based on the first embodiment, further includes a support plate 64 symmetrically arranged on the top of the support platform 8. A hydraulic device 65 is fixed on the top of the support plate 64. The output end of the hydraulic device 65 is fixedly connected to the support plate 66. Insertion posts 67 adapted to the side groove 63 are uniformly arranged on the outer surface of the support plate 66.
[0059] The barrier block 61 is fixed to the bend of the pump pipe 3 by bolts and welding, and the bottom of the support plate 64 is fixedly connected to the top of the support frame 2.
[0060] Because the rotation of the spiral fan 4 is driven by hydraulic action, which in turn drives the main shaft 5 to rotate and generate electricity for the energy-saving generator 7, if a sealing block unit 6 is not added between the main shaft 5 and the pump pipe 3, the inner wall of the main shaft 5 and the pump pipe 3 will be rotated, resulting in a gap. Therefore, by setting up the barrier block 61 and the water-blocking mechanism 68, the sealing performance at this point is increased. At the same time, the vibration sensor 62 is set up. Since the water pressure at the bend of the pump pipe 3 is greater than that at the straight pipe, when the vibration sensor 62 detects a large vibration, the hydraulic devices 65 on both sides will drive the support plate 66 and the insertion column 67 to move. Thus, the insertion column 67 enters the side groove 63 of the barrier block 61, forming an integrated anti-fall-off protection system, which effectively resists the impact of strong water flow and vibration on the sealing structure at this point.
[0061] like Figure 13 As shown, the sealing block unit 6 also includes a water-blocking mechanism 68 disposed on the barrier block 61 inside the pump pipe 3. The water-blocking mechanism 68 is used to protect the sealing of the connection between the main rotating shaft 5 and the pump pipe 3. An inner groove 69 is provided on the main rotating shaft 5 near the water-blocking mechanism 68.
[0062] The outer surface of the main rotating shaft 5 is rotatably connected to the inner wall of the barrier block 61.
[0063] The water-blocking mechanism 68 includes a water-blocking ring 681. Four air pressure pipes 682 are symmetrically arranged on the inner wall of the water-blocking ring 681. A push-in end 683 is slidably connected to one end of the air pressure pipe 682 facing the spiral fan 4. A pressure plate 686 is fixedly connected to the outer surface of the push-in end 683. An ejection end 684 is provided on the side of the air pressure pipe 682 away from the push-in end 683. An insertion block 685 is fixedly connected to the outer surface of the ejection end 684.
[0064] One end of the water-blocking ring 681 is fixedly connected to the outer surface of the barrier block 61, and the size of the insertion block 685 is adapted to the inner groove 69 and can obstruct water flow.
[0065] The water flow impacts the pressure plate 686, which in turn pushes the push end 683 in the air pressure pipe 682, causing the push end 684 and the insertion block 685 to move and enter the inner groove 69 of the main rotating shaft 5, forming a water-proof gap. This increases the resistance of the water flow to the rotating connection between the main rotating shaft 5 and the blocking block 61, and improves the sealing between the main rotating shaft 5 and the blocking block 61.
[0066] The specific workflow is as follows:
[0067] During operation, when the vibration sensor 62 detects significant vibration, the hydraulic devices 65 on both sides drive the support plate 66 and the insertion post 67 to move. This causes the insertion post 67 to enter the side groove 63 of the barrier block 61, forming an integrated anti-detachment protection system. This effectively resists the impact of strong water flow and vibration on the sealing structure at this location. At the same time, the barrier block 61 and the water-blocking mechanism 68 are set up to increase the sealing performance at this location. While the water flow impacts the barrier block 61, it also impacts the pressure plate 686, which pushes the push end 683 in the air pressure pipe 682, causing the push end 684 and the insertion block 685 to move and enter the inner groove 69 of the main rotating shaft 5, forming a water-blocking gap. This increases the resistance of water flow into the rotating connection between the main rotating shaft 5 and the barrier block 61, improving the sealing performance between the main rotating shaft 5 and the barrier block 61.
[0068] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
