Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a submersible pump installation and maintenance frame for a water collection well. Background Technology

[0002] A sump well is a well used to collect and store groundwater or seepage water. It plays an important role in sewage treatment units. Its function is to collect, store and balance the quality and quantity of wastewater. Submersible pumps need to be installed in the sump well to discharge the water, so as to achieve the purpose of waterless construction in the foundation pit.

[0003] Existing water collection well operating frames typically use a straight ladder to allow operators to go up and down the well. When operators go down into the well, they bring the water pump down with them for installation. When the water pump malfunctions and needs repair, workers also go down into the well to disassemble it and then climb the ladder to bring it to the surface for repair.

[0004] However, in actual use, the water collection well contains water. When operators go up and down the well repeatedly, the water is carried to the surface of the ladder, making the ladder slippery and hindering the climb. This can even cause workers to fall, posing a safety hazard. On top of this, workers may also need to climb the ladder with the disassembled water pump to bring it to the ground, which is difficult and dangerous. In view of this, we propose a submersible pump installation and maintenance operation frame for water collection wells. Summary of the Invention

[0005] The purpose of this invention is to provide an installation and maintenance operating frame for a submersible pump in a water collection well, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a submersible pump installation and maintenance operation frame for a water collection well, comprising a U-shaped fixing frame, wherein universal wheels are fixedly installed at the four corners of the bottom surface of the U-shaped fixing frame, and electric telescopic rods are fixedly installed at both ends of the upper surface of the U-shaped fixing frame. Activating the electric telescopic rods can drive a horizontal adjustment mechanism to move vertically. A horizontal adjustment mechanism is provided above the electric telescopic rods. A telescopic climbing mechanism is provided at the center of the upper part of the U-shaped fixing frame, and a lifting mechanism is provided on the upper right side of the telescopic climbing mechanism. The telescopic climbing mechanism includes:

[0007] The mounting frame is positioned above the U-shaped fixing frame. The inner walls of the front and rear sides of the mounting frame are provided with a number of threaded holes in a straight line array. The interior of the mounting frame is provided with multiple sets of climbing ladders in a trapezoidal array. The uppermost climbing ladder in the multiple sets of climbing ladders is provided with an internal hexagon bolt at its upper end. The uppermost climbing ladder can be fixedly installed inside the mounting frame by the internal hexagon bolt.

[0008] Threaded hole two, which is formed on the upper part of the left side surface of the climbing ladder;

[0009] A slide is provided on the right side surface of the climbing ladder, and a slider is slidably connected inside the slide, which can slide up and down inside the slide.

[0010] A fixed plate is fixedly installed on the upper surface of the climbing ladder. A rotating plate is provided on the right side of the fixed plate, and a screw is fixedly installed on the left side surface of the rotating plate. A limit plate is fixedly installed on the left outer side of the screw, penetrating the right side surface of the fixed plate. The limit plate and the rotating plate can limit the screw and prevent the screw from detaching from the fixed plate and being lost.

[0011] Preferably, the size of the threaded hole is adapted to the size of the internal hex bolt.

[0012] Preferably, the size of the second threaded hole is adapted to the size of the screw.

[0013] Preferably, the right surface of the slider corresponding to the upper climbing ladder in the plurality of climbing ladders is fixedly connected to the left surface of the climbing ladder below it.

[0014] Preferably, the lifting mechanism includes:

[0015] The lifting motor is fixedly installed on the right side of the upper surface of the mounting frame. A wire roller is fixedly installed on the left output shaft of the lifting motor. A connecting wire is fixedly installed on the outer side of the wire roller. A mounting plate is fixedly installed on the end of the connecting wire away from the wire roller. Starting the lifting motor can drive the wire roller to rotate.

[0016] An electromagnet is fixedly mounted on the bottom surface of a mounting plate, and can generate magnetic force when energized.

[0017] A fixing rod is fixedly installed on the inner right side surface of the mounting bracket, and a limiting sleeve is fixedly installed on the left end of the fixing rod. The limiting sleeve can guide and limit the connecting line.

[0018] Preferably, the limiting sleeve is fitted onto the outside of the connecting line.

[0019] Preferably, the connecting line is wound around the outside of the roller.

[0020] Preferably, the leveling mechanism includes:

[0021] A fixed crossbar is fixedly installed at the top of the electric telescopic rod, and a moving groove is provided on the side surface of the fixed crossbar near the mounting frame.

[0022] A threaded rod is rotatably mounted on the inner rear wall surface of the moving groove. A moving block is threadedly connected to the outer side of the threaded rod. When the threaded rod rotates, it can drive the moving block to move linearly in the back-and-forth direction under the limitation of the inner wall of the moving groove.

[0023] An adjusting motor is fixedly mounted on the front surface of a fixed crossbar. The output shaft of the adjusting motor passes through the front surface of the fixed crossbar and is fixedly connected to the front end of a threaded rod. Starting the adjusting motor can drive the threaded rod to rotate.

[0024] Preferably, the side surface of the movable block closest to the mounting frame is fixedly connected to the side wall of the mounting frame.

[0025] Compared with the prior art, the present invention provides a mounting and maintenance operating frame for a submersible pump in a water collection well, which has the following advantages:

[0026] 1. The submersible pump installation and maintenance frame for this water collection well allows for adjustment of the position of the uppermost climbing ladder via a combination of threaded hole one and hex bolts. This allows the climbing ladder to be adjusted according to the location of the water collection well, enhancing its versatility. When the frame is not in use, the lower climbing ladder can be slid down, aligning the screw with threaded hole two. Rotating the rotating plate causes the screw to rotate and enter threaded hole two, securing the lower climbing ladder. This allows multiple climbing ladders to be retracted, reducing storage space. After the climbing ladders are installed, workers can stand on the lower climbing ladder and activate the electric telescopic pole to safely reach the water collection well, avoiding accidents during ascent and descent.

[0027] 2. The submersible pump installation and maintenance frame for this water collection well is designed to be used in conjunction with the lifting motor. Starting the lifting motor, the electromagnet, through the cooperation of the rollers, connecting lines, and mounting plate, moves downwards to the protective casing of the pump. At this point, energizing the electromagnet and reversing the lifting motor will raise the pump to the ground. This avoids situations where water in the collection well makes it inconvenient for workers to lift the pump, preventing maintenance. The fixed rod and limiting sleeve ensure the pump remains centered in the collection well during lifting, preventing collisions.

[0028] 3. The installation and maintenance operating frame for the water collection well submersible pump, through the cooperation of the threaded rod, moving groove and moving block, can drive the installation frame to move linearly in the front and back direction when the motor is started, thereby adjusting the position of the telescopic climbing mechanism and the lifting mechanism, and enhancing the adaptability of the operating frame.

[0037] like Figures 1-7 As shown, the present invention provides a technical solution: a submersible pump installation and maintenance operating frame for a water collection well, including a U-shaped fixed frame 1. When moving the operating frame, the notch of the U-shaped fixed frame 1 can be oriented towards the water collection well to avoid the water collection well obstructing the movement of the operating frame. Universal wheels 2 are fixedly installed at the four corners of the bottom surface of the U-shaped fixed frame 1. The universal wheels 2 are equipped with a self-locking structure, allowing the operating frame to move in any direction via the universal wheels 2 and to lock after movement. Electric telescopic rods 3 are fixedly installed at both the left and right ends of the upper surface of the U-shaped fixed frame 1. Controlling the electric telescopic rods 3 can drive the mechanism above to lift and lower to adapt to water collection wells of different depths. A horizontal adjustment mechanism 4 is provided above the electric telescopic rods 3. A telescopic climbing mechanism 5 is provided at the center of the upper part of the U-shaped fixed frame 1, and a lifting mechanism 6 is provided on the right side above the telescopic climbing mechanism 5.

[0038] The telescopic climbing mechanism 5 includes: a mounting frame 501, threaded holes 505, a sliding groove 506, and a fixing plate 508. The mounting frame 501 is positioned above the U-shaped fixing frame 1. The inner surfaces of the front and rear sides of the mounting frame 501 are provided with a number of threaded holes 502 arranged in a straight line array. The interior of the mounting frame 501 is arranged in a trapezoidal array with multiple sets of climbing ladders 503. Two hexagonal socket head cap screws 504 are provided at the top of the uppermost climbing ladder 503. The uppermost climbing ladder 503 of the multiple climbing ladders 503 is not set at the front and rear ends of the uppermost climbing ladder 503. The size of the threaded hole 502 is compatible with the size of the internal hex bolt 504. The uppermost climbing ladder 503 of the multiple climbing ladders 503 can be fixedly installed inside the mounting bracket 501 through the cooperation of the threaded hole 502 and the internal hex bolt 504. By connecting with the threaded hole 502 at different positions, the climbing ladder 503 can be adjusted to different positions to enhance the adaptability of the telescopic climbing mechanism 5.

[0039] Threaded hole 505 is formed on the upper left side surface of climbing ladder 503, and slide groove 506 is formed on the right side surface of climbing ladder 503. Slider 507 is slidably connected inside slide groove 506. The right side surface of the slider 507 corresponding to the upper climbing ladder 503 in multiple climbing ladders 503 is fixedly connected to the left side surface of the climbing ladder 503 below it. The lower climbing ladder 503 can slide up and down on the right side of the upper climbing ladder 503. Fixed plate 508 is fixedly installed on the upper surface of climbing ladder 503. Rotating plate 509 is provided on the right side of fixed plate 508. Screw 510 is fixedly installed on the left side surface of rotating plate 509. The size of threaded hole 505 is compatible with the size of screw 510.

[0040] A limiting plate 511 is fixedly installed on the right side surface of the fixing plate 508 through the outer left side of the screw 510. The limiting plate 511 can limit the screw 510 to prevent it from detaching from the fixing plate 508 and being lost. When the lower climbing ladder 503 moves upward and the screw 510 aligns with the threaded hole 505, the rotating plate 509 can be rotated to drive the screw 510 to rotate into the threaded hole 505, thus fixing the lower climbing ladder 503. This allows multiple climbing ladders 503 to retract. When not in use, they can be retracted into the bottom of the mounting bracket 501 to reduce storage space. At the same time, the number of climbing ladders 503 can be increased at any time by inserting the slider 507 corresponding to the climbing ladder 503 to be added into the groove 506 of the lowest climbing ladder 503. This enhances the adaptability of the telescopic climbing mechanism 5, making it suitable for water collection wells of different depths.

[0041] The lifting mechanism 6 includes a lifting motor 601, an electromagnet 605, and a fixed rod 606. The lifting motor 601 is fixedly installed on the right side of the upper surface of the mounting frame 501. A wire roller 602 is fixedly installed on the left output shaft of the lifting motor 601. Starting the lifting motor 601 can drive the wire roller 602 to rotate. A connecting wire 603 is fixedly installed on the outside of the wire roller 602. The connecting wire 603 is wound around the outside of the wire roller 602. When the wire roller 602 rotates, it can realize the winding or unwinding of the connecting wire 603. The connecting wire 603 has wires inside, which can be electrically connected to the electromagnet 605.

[0042] A mounting plate 604 is fixedly installed at the end of the connecting wire 603 away from the roller 602. An electromagnet 605 is fixedly installed on the bottom surface of the mounting plate 604. When the connecting wire 603 is wound or released, it can drive the mounting plate 604 and the electromagnet 605 to move up and down. When the electromagnet 605 descends above the water pump, it can be energized to generate magnetic force, magnetically attracting the iron protective shell outside the water pump. Then, the connecting wire 603 is wound around the outside of the water pump, and winding the connecting wire 603 allows the water pump to... When the pump is lifted, the electromagnet 605 can be replaced with a hook lock. The fixing rod 606 is fixedly installed on the inner right side of the mounting frame 501. The left end of the fixing rod 606 is fixedly installed with a limiting sleeve 607. The limiting sleeve 607 is sleeved on the outside of the connecting line 603. The fixing rod 606 can support and limit the limiting sleeve 607, and the limiting sleeve 607 can limit the connecting line 603. This ensures that when the connecting line 603 is being wound up to lift the water pump, the water pump can be kept in the center position, preventing the water pump from colliding with the side wall of the water collection well and causing damage.

[0043] The horizontal adjustment mechanism 4 includes: a fixed horizontal column 401, a threaded rod 403, and an adjusting motor 405. The fixed horizontal column 401 is fixedly installed at the top of the electric telescopic rod 3 and can move up and down with the electric telescopic rod 3. A moving groove 402 is opened on the side surface of the fixed horizontal column 401 near the mounting bracket 501. The threaded rod 403 is rotatably installed on the inner wall surface of the rear side of the moving groove 402. A moving block 404 is threadedly connected to the outer side of the threaded rod 403. The outer wall of the moving block 404 fits against the inner wall of the moving groove 402. When the threaded rod 403 rotates, the moving groove 402 moves in a certain direction. The inner wall limiter can drive the moving block 404 to move linearly in the front and back direction. The side surface of the moving block 404 near the mounting bracket 501 is fixedly connected to the side wall of the mounting bracket 501. When the moving block 404 moves, it can drive the mounting bracket 501 to move synchronously. The adjusting motor 405 is fixedly installed on the front surface of the fixed cross column 401. The output shaft of the adjusting motor 405 passes through the front surface of the fixed cross column 401 and is fixedly connected to the front end of the threaded rod 403. When the adjusting motor 405 is started, it can drive the threaded rod 403 to rotate, thereby adjusting the position of the mounting bracket 501.

[0044] In this invention, during use, the operating frame is moved to the top of the water collection well by the universal wheels 2. The adjusting motor 405 is then activated, and the mounting frame 501 is moved to the top of the water collection well by the movement slot 402, the movement block 404, and the threaded rod 403. Then, according to the position of the water collection well, the uppermost climbing ladder 503 is fixed to the desired threaded hole 502 using hexagonal bolts 504. Next, the rotating plate 509 corresponding to the lower climbing ladder 503 is rotated, causing the screw 510 to disengage from the threaded hole 505, allowing the climbing ladder 503 to extend downwards. Workers can then climb onto the lowermost climbing ladder 503. The electric telescopic rod 3 is then activated to retract, allowing workers to reach the water collection well without climbing up or down, enhancing safety. If there is water inside the water collection well and it is inconvenient for workers to move the water pump on the ground, the lifting motor can be activated. Release the connecting wire 603, causing the electromagnet 605 to move downwards to above the water pump. Electrify the electromagnet 605 to generate magnetic force, magnetically attracting the water pump's iron protective casing. Then, wind the connecting wire 603 around the outside of the water pump. Start the lifting motor 601 to reverse and rewind the connecting wire 603, thus lifting the water pump to the bottom. The connecting wire 603 is limited by the fixed rod 606 and the limiting sleeve 607, ensuring the water pump remains centered in the collection well during lifting, preventing damage from collisions with the inner wall of the collection well. When the operating frame is not in use, the lower climbing ladder 503 can be moved upwards until the screw 510 aligns with the second threaded hole 505. Rotating the rotating plate 509 will then rotate the screw 510 into the second threaded hole 505, fixing the lower climbing ladder 503. This allows multiple climbing ladders 503 to retract, reducing storage space.

[0045] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
