Description

Technical Field

[0001] This invention relates to the field of integrated pump gate technology, specifically an assembled integrated pump gate. Background Technology

[0002] Modern pump-gate systems mostly integrate the pump and gate into a single unit, with the pump mounted on the gate. In traditional pump-gate systems, the pumping station and gate were separate; a separate channel was created on one side of the existing river, one channel for the gate and the other for the pumping station. Modern integrated pump-gate systems simply require constructing the gate on the original river channel and installing the pump unit on it, resulting in relatively lower costs.

[0003] The water pumps on the integrated pump gate are vulnerable components that require frequent maintenance. Since the pump gate needs to be opened to expose the pumps above the water surface when the pump gate is being maintained, an additional gate needs to be built on the river as a maintenance gate. When the pump gate is opened for maintenance, the maintenance gate is closed to block the water flow. Although the integrated pump gate reduces the cost of opening another river channel, the construction cost of the maintenance gate is not low.

[0004] Based on this, the present invention designs an assembled integrated pump gate to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an assembled integrated pump gate to solve the problems mentioned in the background art.

The first and second inclined blocks are fixedly connected to the upper and lower sides of the outer wall of the partially movable tube. The third inclined block is located above the first inclined block and is slidably connected to the gate body in the vertical direction. The fourth inclined block is located below the second inclined block and is fixedly connected to the gate body. The inclined surfaces of the first and second inclined blocks both face away from the gate body, while the inclined surfaces of the third and fourth inclined blocks both face the gate body. The inclined surface of the first inclined block can contact the inclined surface of the third inclined block, and the inclined surface of the second inclined block can contact the inclined surface of the fourth inclined block. A driven pushing component for pushing the third inclined block to slide up and down is provided between the sliding sleeve and the gate body.

[0009] As a further embodiment of the present invention, the driven push assembly includes a first rack and a pressing member. The first rack is slidably connected to the gate body in the vertical direction. A Z-shaped rod is fixedly connected to the bottom of the first rack. The pressing member is fixedly connected to a sliding sleeve. The lower side of the end of the pressing member can contact the end of the Z-shaped rod away from the first rack. The first rack meshes with a first gear. The first gear is rotatably connected to the gate body. A second gear is fixedly connected to the rotation shaft of the first gear. The size of the second gear is larger than that of the first gear. The second gear meshes with a second rack on the same side as the first rack. The second rack is slidably connected to the gate body in the vertical direction. The lower end of the second rack is fixedly connected to a third inclined block. A fixing plate is fixedly connected to the upper end of the second rack. A second spring is fixedly connected between the lower side of the fixing plate and the gate body.

[0011] As a further embodiment of the present invention, the driven locking mechanism includes a U-shaped frame and a lane-changing limiting strip. The U-shaped frame is fixedly connected to the outer side of the vertical guide column. A pin is slidably connected to the U-shaped frame.

[0013] As a further embodiment of the present invention, the motor is model Y315M-4.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention enables the submersible pump and impeller to be moved upwards to the top of the gate body's maintenance platform via a drive mechanism. Maintenance personnel can then perform maintenance on the submersible pump and impeller from the maintenance platform on top of the gate body, thereby avoiding the need to open the gate body and eliminating the need for a separate maintenance gate. This makes pump maintenance more convenient and avoids the cost of constructing a maintenance gate.

[0016] This invention enables the submersible pump and impeller to detach from the partially movable tube during the process of moving them to the top of the maintenance platform through the cooperation of the driven locking mechanism and the driven transmission mechanism. This allows maintenance personnel to directly inspect the submersible pump and impeller, which are vulnerable components. After the inspection is completed, the submersible pump and impeller can be retracted into the partially movable tube through the cooperation of the driven locking mechanism and the driven transmission mechanism. This achieves automatic disassembly and assembly of the submersible pump, impeller and partially movable tube, thereby improving the maintenance efficiency of the water pump.

[0017] When the partially movable tube begins to move upward, the automatic docking mechanism, in conjunction with the first spring, allows the partially movable tube to slide a certain distance away from the gate body. Furthermore, as the partially movable tube is about to move downward and align with the fixed tube, the automatic docking mechanism moves the partially movable tube towards the fixed tube until the docking is complete. Thus, during the docking and separation of the partially movable tube and the fixed tube, friction between their interfaces can be minimized, preventing damage caused by friction and thereby improving the service life of both the fixed tube and the partially movable tube.

[0027] Please see Figures 1-7 This invention provides a technical solution: an assembled integrated pump gate, comprising a gate body 1, a fixed pipe 2 fixedly connected to one bottom side of the gate body 1, and a partially movable pipe 3 provided at the bottom side of the other bottom side of the gate body 1, the partially movable pipe 3 being able to communicate with the fixed pipe 2, a sliding sleeve 4 slidably connected to the outer wall of the partially movable pipe 3 in the front-back direction, vertical slide rails 5 slidably connected to both sides of the sliding sleeve 4, the vertical slide rails 5 being fixedly connected to the gate body 1, a driving mechanism for driving the sliding sleeve 4 to slide up and down on the gate body 1, a first spring 6 fixedly connected between the side of the sliding sleeve 4 away from the gate body 1 and the outer wall of the partially movable pipe 3, an automatic docking mechanism provided between the gate body 1 and the partially movable pipe 3, the partially movable pipe 3 being able to communicate with the fixed pipe 2 through the automatic docking mechanism; the outer wall of the partially movable pipe 3 is fixedly connected to both sides of its upper notch. A vertical guide post 7 is connected to the gate body 1. Each vertical guide post 7 is slidably connected to a slide bar 8. The two slide bars 8 are fixedly connected to an arc-shaped tube shell 9 located at the upper notch of the partially movable tube 3. The size of the arc-shaped tube shell 9 matches the size of the upper notch of the partially movable tube 3. A submersible pump 10 located inside the partially movable tube 3 is fixedly connected to the lower side of the arc-shaped tube shell 9. An impeller 11 is fixedly connected to the output shaft of the submersible pump 10. A driven transmission mechanism for pushing the slide bar 8 to slide up and down relative to the vertical guide post 7 is provided between the gate body 1 and the vertical guide post 7. A driven locking mechanism for fixing the slide bar 8 relative to the vertical guide post 7 is provided between the vertical guide post 7 and the gate body 1 support. A maintenance platform 39 is fixedly connected to the upper end of the side of the gate body 1 near the partially movable tube 3. A through hole matching the size of the arc-shaped tube shell 9 is opened on the maintenance platform 39. The through hole is located directly above the arc-shaped tube shell 9.

[0028] When the above scheme is put into actual use, when the water pump needs to be repaired, it is not necessary to open the gate body 1. First, the sliding sleeve 4 is driven upward by the drive mechanism. The sliding sleeve 4 drives the partially movable tube 3 upward. During the initial upward movement of the partially movable tube 3, the automatic docking mechanism automatically releases the partially movable tube 3. Under the elastic force of the first spring 6, the partially movable tube 3 slides a certain distance away from the fixed tube 2. Thus, the partially movable tube 3 can avoid the structure installed on the side of the gate body 1. When the partially movable tube 3 moves up to near the maintenance platform 39, the driven locking mechanism is triggered and runs in reverse, so that the sliding bar 8 can slide relative to the vertical guide column 7. Immediately afterwards, the driven transmission mechanism is triggered, so that the sliding bar 8 slides upward relative to the vertical guide column 7. The sliding bar 8 drives The arc-shaped casing 9 moves upward, driving the submersible pump 10 and impeller 11 upward and gradually away from the partially movable tube 3. When the partially movable tube 3 moves upward to be close to the lower surface of the maintenance platform 39, the drive mechanism stops. At this time, the arc-shaped casing 9, along with the submersible pump 10 and impeller 11, moves upward to the top of the maintenance platform 39, making it convenient for maintenance personnel to perform maintenance. After maintenance is completed, the drive mechanism reverses, driving the sliding sleeve 4 and the partially movable tube 3 downward. During the initial downward movement of the partially movable tube 3, the driven transmission mechanism causes the slide bar 8 to slide relative to the vertical guide column 7 until the submersible pump 10 and impeller 11 retract into the partially movable tube 3 and the arc-shaped casing 9 closes with the upper notch of the partially movable tube 3. Immediately afterwards, the driven locking mechanism locks the slide bar 8 against the vertical guide column. 7 is relatively fixed, thus fixing the arc-shaped tube shell 9 to the partially movable tube 3; when the partially movable tube 3 moves down to near the fixed tube 2, the automatic docking mechanism is triggered, and the automatic docking mechanism gradually pushes the partially movable tube 3 towards the gate body 1. When the partially movable tube 3 moves down to align with the fixed tube 2, the partially movable tube 3 is exactly docked with the fixed tube 2, and the automatic docking mechanism can make the interface of the partially movable tube 3 and the interface of the fixed tube 2 fit tightly. At this time, the drive mechanism stops running, thus completing the maintenance work of the water pump; in this way, the pump gate can move the submersible pump 10 and impeller 11 to the top of the maintenance platform 39 of the gate body 1 through the drive mechanism, and the maintenance personnel can inspect the submersible pump 10 and impeller 11 on the maintenance platform 39 at the top of the gate body 1. The impeller 11 is inspected, thus avoiding the opening of the gate body 1 and eliminating the need for a separate inspection gate, making pump maintenance more convenient and avoiding the cost of constructing an inspection gate. The pump gate can disengage the submersible pump 10 and impeller 11 from the partially movable tube 3 during the process of moving them to the top of the inspection platform 39 through the cooperation of the driven locking mechanism and the driven transmission mechanism. This allows maintenance personnel to directly inspect the submersible pump 10 and impeller 11, which are vulnerable components. After the inspection is completed, the submersible pump 10 and impeller 11 can be retracted into the partially movable tube 3 through the cooperation of the driven locking mechanism and the driven transmission mechanism. This achieves automatic disassembly and assembly between the submersible pump 10, impeller 11 and the partially movable tube 3, thereby improving the pump maintenance efficiency.

[0029] The drive mechanism includes a motor 12, which is fixedly connected to the top of the gate body 1. The output shaft of the motor 12 is fixedly connected to two worm gears 13, which are rotatably connected to the gate body 1. Each worm gear 13 is meshed with a worm wheel 14, which is fixedly connected to a lead screw 15. The lead screw 15 is rotatably connected to the vertical slide rail 5 and threadedly connected to the sliding sleeve 4.

[0030] When the above scheme is put into actual use, the motor 12 starts, the motor 12 drives the worm 13 to rotate, the worm 13 drives the worm wheel 14 to rotate, the worm wheel 14 drives the lead screw 15 to rotate, and the lead screw 15 drives the sliding sleeve 4 to move up or down along the vertical slide rail 5, thereby realizing the control of the up and down movement of the incompletely movable tube 3.

[0031] The automatic docking mechanism includes a first inclined block 16, a second inclined block 17, a third inclined block 18, and a fourth inclined block 19. The first inclined block 16 and the second inclined block 17 are fixedly connected to the upper and lower sides of the outer wall of the partially movable tube 3. The third inclined block 18 is located above the first inclined block 16 and is slidably connected to the gate body 1 in the vertical direction. The fourth inclined block 19 is located below the second inclined block 17 and is fixedly connected to the gate body 1. The inclined surfaces of the first inclined block 16 and the second inclined block 17 are both facing away from the gate body 1. The inclined surfaces of the third inclined block 18 and the fourth inclined block 19 are both facing the gate body 1. The inclined surface of the first inclined block 16 can contact the inclined surface of the third inclined block 18, and the inclined surface of the second inclined block 17 can contact the inclined surface of the fourth inclined block 19. A driven pushing component for pushing the third inclined block 18 to slide up and down is provided between the sliding sleeve 4 and the gate body 1.

[0032] When the above scheme is put into actual use, when the partially movable tube 3 moves down to near the fixed tube 2, the inclined surface of the second inclined block 17 contacts the fourth inclined block 19. The fourth inclined block 19 pushes the partially movable tube 3 towards the gate body 1 through the second inclined block 17. At the same time, the driven push component is triggered, causing the third inclined block 18 to slide downward relative to the partially movable tube 3. After the fourth inclined block 19 pushes the second inclined block 17 a short distance, the third inclined block 18 moves down to contact the inclined surface of the first inclined block 16 and pushes the partially movable tube 3 synchronously with the fourth inclined block 19. When the partially movable tube 3 moves down to align with the fixed tube 2, the partially movable tube 3 is pushed by the third inclined block 18 and the fourth inclined block 19 to be close to the fixed tube 2, thereby achieving the docking of the partially movable tube 3 and the fixed tube 2. As the partially movable tube 3 moves up away from the fixed tube 2, the second inclined block 17 moves up with the partially movable tube 3 and gradually moves away. The fourth inclined block 19 and the third inclined block 18 slide upward relative to the first inclined block 16 under the action of the driven push component. At this time, the partially movable tube 3 slides a distance away from the gate body 1 under the action of the first spring 6, thereby realizing the separation of the partially movable tube 3 from the fixed tube 2. In this way, when the partially movable tube 3 begins to move upward, the pump gate can make the partially movable tube 3 slide a distance away from the gate body 1 through the cooperation of the automatic docking mechanism and the first spring 6. And when the partially movable tube 3 is about to move down to align with the fixed tube 2, the automatic docking mechanism makes the partially movable tube 3 move towards the fixed tube 2 until the partially movable tube 3 completes the docking with the fixed tube 2. In this way, during the docking and separation process of the partially movable tube 3 and the fixed tube 2, the friction between the interface of the partially movable tube 3 and the fixed tube 2 can be avoided as much as possible, thereby avoiding damage caused by friction and improving the service life of the fixed tube 2 and the partially movable tube 3.

[0033] The driven push assembly includes a first rack 20 and a pressing member 22. The first rack 20 is slidably connected to the gate body 1 in the vertical direction. A Z-shaped rod 21 is fixedly connected to the bottom of the first rack 20. The pressing member 22 is fixedly connected to the sliding sleeve 4. The lower side of the end of the pressing member 22 can contact the end of the Z-shaped rod 21 away from the first rack 20. The first rack 20 meshes with a first gear 23. The first gear 23 is rotatably connected to the gate body 1. A second gear 24 is fixedly connected to the rotating shaft of the first gear 23. The size of the second gear 24 is larger than that of the first gear 23. The second gear 24 meshes with a second rack 25 on the same side as the first rack 20. The second rack 25 is slidably connected to the gate body 1 in the vertical direction. The lower end of the second rack 25 is fixedly connected to a third inclined block 18. A fixing plate 26 is fixedly connected to the upper end of the second rack 25. A second spring 27 is fixedly connected between the lower side of the fixing plate 26 and the gate body 1.

[0034] When the above scheme is put into actual use, when the second inclined block 17 moves down with the partially movable tube 3 to contact the inclined surface of the fourth inclined block 19, the pressing member 22 just touches the Z-shaped rod 21 and pulls down the pressing member 22 through the Z-shaped rod 21. The pressing member 22 slides down synchronously with the partially movable tube 3 and drives the first gear 23 to rotate. The first gear 23 drives the second gear 24 to rotate. The second gear 24 drives the second rack 25 to slide down. The sliding speed of the second rack 25 is greater than the sliding speed of the partially movable tube 3. The second rack 25 pushes the third inclined block 18 to slide down. When the partially movable tube 3 begins to move up away from the fixed tube 2, the pressing member 22 moves up with the partially movable tube 3. At this time, the fixed plate 26 pulls the second rack 25 up under the elastic force of the second spring 27. Similarly, it rotates in the opposite direction. The second rack 25 drives the third inclined block 18 to move up relative to the partially movable tube 3, thereby controlling the up and down sliding of the third inclined block 18 relative to the partially movable tube 3.

[0035] The driven transmission mechanism includes a third rack 28 and a fourth rack 30. The third rack 28 is fixedly connected to the side of the slide bar 8 near the gate body 1. The third rack 28 meshes with a third gear 29. The third gear 29 is rotatably connected to the vertical guide column 7. The fourth rack 30 is fixedly connected to the upper end of the side of the gate body 1 near the slide bar 8. The fourth rack 30 can mesh with the third gear 29.

[0036] When the above scheme is put into actual use, when the partially movable tube 3 moves up to be close to the inspection platform 39, the third gear 29 meshes with the fourth rack 30. The fourth rack 30 drives the third gear 29 to rotate, and the third gear 29 drives the slide bar 8 to slide up along the vertical guide column 7 through the third rack 28, thereby controlling the slide bar 8 to move up relative to the partially movable tube 3. When the partially movable tube 3 begins to move down and away from the inspection platform 39, the same principle applies, and the transmission is reversed, thereby causing the slide bar 8 to move down relative to the partially movable tube 3.

[0037] The driven locking mechanism includes a U-shaped frame 31 and a lane-changing limiting strip 36. The U-shaped frame 31 is fixedly connected to the outside of the vertical guide column 7. The U-shaped frame 31 is slidably connected to a pin 32. The vertical guide column 7 and the slide bar 8 are both provided with pin holes corresponding to the pin 32. A fixed plate 33 is fixedly connected to the middle of the outer wall of the pin 32. A third spring 34 is provided between the side of the fixed plate 33 away from the vertical guide column 7 and the U-shaped frame 31. The third spring 34 is sleeved on the outside of the pin 32. A contact rod 35 is fixedly connected to the end of the pin 32 away from the vertical guide column 7. The lane-changing limiting strip 36 is fixedly connected to the upper end of the gate body 1 near the slide bar 8. The side of the contact rod 35 near the vertical guide column 7 can contact the lane-changing limiting strip 36.

[0038] When the above scheme is put into actual use, during the upward movement of the partially movable tube 3, before the driven transmission mechanism is triggered, the inclined surface at the bottom of the lane-changing limit bar 36 first contacts the side of the contact rod 35 near the vertical guide post 7. As the partially movable tube 3 moves upward, the contact rod 35 moves away from the vertical guide post 7 under the push of the inclined surface of the lane-changing limit bar 36. When the contact rod 35 slides up to the point where its vertical surface contacts the vertical surface, the contact rod 35 drives the pin 32 to exit the pin hole on the slide bar 8, thereby allowing the slide bar 8 to slide relative to the vertical guide post 7. The driven transmission mechanism is triggered, and during the subsequent movement on the partially movable tube 3, the contact rod 35 remains in contact with the vertical surface of the lane change limit bar 36. When the partially movable tube 3 begins to move down until the driven transmission mechanism stops running, the pin hole on the vertical guide post 7 is aligned with the pin hole on the slide bar 8. As the partially movable tube 3 moves down, the contact rod 35 slides down to the inclined surface at the bottom of the lane change limit bar 36. At this time, the pin 32 is inserted into the pin hole on the slide bar 8 under the elastic force of the third spring 34, thereby fixing the vertical guide post 7 and the slide bar 8 relative to each other.

[0039] The fixed pipe 2 has a sealing cover 37 at the end furthest from the gate body 1. The upper side of the sealing cover 37 is hinged to the fixed pipe 2, and a hydraulic cylinder 38 is hinged to the middle of the side of the sealing cover 37 furthest from the fixed pipe 2. The upper end of the hydraulic cylinder 38 is hinged to the gate body 1. During operation, before the submersible pump 10 is started, the sealing cover 37 can be pulled up by the hydraulic cylinder 38 until it is fully open. After the submersible pump 10 is turned off, the sealing cover 37 can be pushed down by the hydraulic cylinder 38 until it is closed. The motor 12 is model Y315M-4.
