Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology, and in particular relates to a motor connection structure for a backwashing bar screen cleaning device. Background Technology

[0002] In urban wastewater treatment plants, backwashing bar screens can be installed at the inlet or before other treatment stages to intercept and remove large particulate impurities and floating matter in wastewater, protecting the normal operation of subsequent treatment equipment. Backwashing bar screens are mainly used to intercept and remove various solid particles and floating matter in the pretreatment process of wastewater, such as suspended solids, fibers, paper scraps, etc. in urban wastewater and industrial wastewater, so that the subsequent treatment process can proceed smoothly.

[0003] However, the above-mentioned device still has the following problems during implementation:

[0004] Existing technology typically requires backwash bar screen cleaning equipment to be installed at the water inlet. The motors on these equipment are usually fixed with multiple bolts. It is crucial to ensure that the tightening torque of each bolt is consistent, otherwise the motor may become unbalanced, increasing the complexity and difficulty of installation. Therefore, a motor connection structure for backwash bar screen cleaning equipment is proposed to solve the above problems. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a motor connection structure for a backwash bar screen cleaning device, which has the advantage of convenient connection and can overcome the above-mentioned problems or at least partially solve the problem that the motors on the backwash bar screen cleaning device are fixed by multiple bolts. The multiple bolts need to ensure that the tightening torque of each bolt is consistent, otherwise it may lead to unbalanced motor installation, which increases the complexity and difficulty of installation.

[0006] This utility model is implemented as follows: a motor connection structure for a backwashing bar screen cleaning device includes a cleaning device, a connecting shell, an adjusting block, and an output motor. The front side of the cleaning device is fixedly connected to the rear side of the connecting shell, the adjusting block is movably connected to the inner cavity of the connecting shell, and the front side of the adjusting block penetrates the connecting shell and is movably connected to the output motor.

[0007] The inner cavity of the adjusting block is provided with an installation groove, the left side of the connecting shell is provided with a control hole, and the front side of the adjusting block is provided with a docking groove.

[0008] A positioning component is disposed within the cavity of the mounting slot.

[0009] As a preferred embodiment of this utility model, a docking block is fixedly connected to the rear side of the output motor for use with the docking groove. The docking block is inserted into the inner cavity of the docking groove. The top and bottom of the docking block are provided with clamping grooves. By setting the docking block and clamping grooves, after the output motor is docked with the adjustment block, the docking block will be inserted into the docking groove, which can position the output motor and align the clamping groove and the clamping block.

[0010] In a preferred embodiment of this invention, the positioning component includes two movable plates movably connected to the inner cavity of the mounting groove. Springs are fixedly connected to opposite sides of each of the two movable plates. A clamping plate, which mates with a clamping groove, is fixedly connected to the front side of each movable plate. Opposite sides of the two clamping plates penetrate the mounting groove and extend into the inner cavity of the clamping groove. By providing the positioning component, after the clamping plate is inserted into the clamping groove, the pressure exerted by the springs on the movable plates causes the movable plates to apply pressure to the clamping plates, preventing the clamping plates from detaching within the clamping groove.

[0011] As a preferred embodiment of this utility model, each of the two movable plates has a stroke groove on its opposite side. A stroke rod is movably connected to the inner cavity of the stroke groove. The side of the stroke rod closest to the inner wall of the mounting groove is fixedly connected to the inner wall of the mounting groove. By setting the stroke groove and the stroke rod, the stroke rod and the stroke groove can control the movement position of the movable plate when the movable plate moves to compress the spring, so that the movable plate moves more stably when it is compressed.

[0012] As a preferred embodiment of this utility model, the rear side of the movable plate is provided with an extrusion groove, and the inner cavity of the mounting groove is movably connected to an extrusion block that cooperates with the extrusion groove. By setting the extrusion groove and the extrusion block, when it is necessary to move the two movable plates simultaneously, the movement of the extrusion block will extrude the inner wall of the extrusion groove, and the extrusion force generated at this time will drive the two movable plates away from each other and extrude the spring.

[0013] As a preferred embodiment of this utility model, a tension spring is fixedly connected to the rear side of the extrusion block, and there are multiple tension springs. The rear side of the tension spring is fixedly connected to the inner wall of the mounting groove. A pull rod is fixedly connected to the left side of the extrusion block. The left side of the pull rod passes through the mounting groove and extends to the outside of the connecting shell. By setting tension springs and pull rods, when the extrusion block does not need to move, the pulling force of multiple tension springs on the extrusion block can position the extrusion block, so that the extrusion block will not cause the pull rod to move randomly.

[0014] As a preferred embodiment of this utility model, the top and bottom of the pull rod are fixedly connected to limit plates, and the left side of the connecting shell is provided with a limit groove for use with the limit plates. The limit plates are inserted into the inner cavity of the limit groove. By setting the limit plates and limit grooves, when the pull rod drives the limit plates to be inserted into the limit grooves at different positions, the adjusting block can be positioned at different positions in the connecting shell, so that the output motor can adjust the tension of the belt.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes an output motor, mounting slot, control hole, docking slot, and positioning component in conjunction. The spring undergoes elastic deformation, causing two moving plates to return to their original positions. The movement of the moving plates causes the clamping plate to insert into the clamping slot, thus fixing the motor's position. This solves the problem that motors in backwashing bar screens are typically fixed with multiple bolts, requiring consistent tightening torque for each bolt to prevent motor imbalance and increase installation complexity and difficulty.

[0022] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 4As shown in the figure, the present invention provides a motor connection structure for a backwashing bar cleaning device, including a cleaning device 1, a connecting shell 2, an adjusting block 3 and an output motor 4. The front side of the cleaning device 1 is fixedly connected to the rear side of the connecting shell 2, the adjusting block 3 is movably connected to the inner cavity of the connecting shell 2, and the front side of the adjusting block 3 penetrates the connecting shell 2 and is movably connected to the output motor 4.

[0025] The inner cavity of the adjusting block 3 is provided with an installation groove 5, the left side of the connecting shell 2 is provided with a control hole 6, and the front side of the adjusting block 3 is provided with a docking groove 7.

[0026] Positioning component 8 is disposed in the inner cavity of mounting slot 5.

[0027] refer to Figure 3 The rear side of the output motor 4 is fixedly connected to a docking block 9 that works with the docking groove 7. The docking block 9 is inserted into the inner cavity of the docking groove 7. The top and bottom of the docking block 9 are provided with clamping grooves 10.

[0028] Using the above solution: By setting the docking block 9 and the clamping groove 10, after the output motor 4 docks with the adjusting block 3, the docking block 9 will be inserted into the docking groove 7, which can position the output motor 4 and make the clamping groove 10 and the clamping block aligned.

[0029] refer to Figure 4 The positioning component 8 includes two movable plates 81, which are movably connected to the inner cavity of the mounting groove 5. Springs 82 are fixedly connected to opposite sides of the two movable plates 81. A clamping plate 83 that cooperates with the clamping groove 10 is fixedly connected to the front side of the movable plate 81. The opposite sides of the two clamping plates 83 pass through the mounting groove 5 and extend into the inner cavity of the clamping groove 10.

[0030] Using the above solution: After the positioning component 8 is set and the clamping plate 83 is inserted into the clamping groove 10, the pressure of the moving plate 81 by the spring 82 will cause the moving plate 81 to apply pressure to the clamping plate 83, so that the clamping plate 83 will not detach in the clamping groove 10.

[0031] refer to Figure 4 Both movable plates 81 have stroke grooves 11 on opposite sides. The inner cavity of the stroke groove 11 is movably connected to a stroke rod 12. The side of the stroke rod 12 closest to the inner wall of the mounting groove 5 is fixedly connected to the inner wall of the mounting groove 5.

[0032] By adopting the above scheme: by setting the stroke groove 11 and the stroke rod 12, when the moving plate 81 moves the compression spring 82, the stroke rod 12 and the stroke groove 11 can control the moving position of the moving plate 81, so that the moving plate 81 moves more stably when it is compressed.

[0033] refer to Figure 4The rear side of the movable plate 81 is provided with an extrusion groove 13, and the inner cavity of the mounting groove 5 is movably connected to an extrusion block 14 that cooperates with the extrusion groove 13.

[0034] The above solution is adopted: by setting the extrusion groove 13 and the extrusion block 14, when it is necessary to drive the two moving plates 81 to move at the same time, the movement of the extrusion block 14 will extrude the inner wall of the extrusion groove 13. The extrusion force generated at this time will drive the two moving plates 81 to move away from each other and extrude the spring 82.

[0035] refer to Figure 4 A tension spring 15 is fixedly connected to the rear side of the extrusion block 14, and there are multiple tension springs 15. The rear side of the tension spring 15 is fixedly connected to the inner wall of the mounting groove 5. A pull rod 16 is fixedly connected to the left side of the extrusion block 14. The left side of the pull rod 16 passes through the mounting groove 5 and extends to the outside of the connecting shell 2.

[0036] The above solution is adopted: by setting tension springs 15 and pull rods 16, when the pressing block 14 does not need to move, the tension of multiple tension springs 15 on the pressing block 14 can position the pressing block 14, so that the pressing block 14 will not cause the pull rod 16 to move randomly.

[0037] refer to Figure 2 and Figure 3 The top and bottom of the pull rod 16 are fixedly connected to the limiting plate 17. The left side of the connecting shell 2 is provided with a limiting groove 18 that cooperates with the limiting plate 17. The limiting plate 17 is inserted into the inner cavity of the limiting groove 18.

[0038] The above solution is adopted: by setting a limiting plate 17 and a limiting groove 18, when the pull rod 16 drives the limiting plate 17 to be inserted into the limiting groove 18 at different positions, the adjusting block 3 can be positioned at different positions in the connecting shell 2, so that the output motor 4 can adjust the tension of the belt.

[0039] The working principle of this utility model:

[0040] In use, pulling the lever 16 causes the pressing block 14 to move within the mounting groove 5. The movement of the pressing block 14 will press the inner wall of the pressing groove 13. The resulting pressing force will cause the two moving plates 81 to move away from each other and press the spring 82. The movement of the moving plates 81 will cause the two clamping plates 83 to move away from each other. Then, the output motor 4 is picked up and connected to the adjusting block 3. When the connecting block 9 is inserted into the connecting groove 7, the lever 16 is pushed back to its original position. At this time, the spring 82 will undergo elastic deformation, causing the two moving plates 81 to return to their original position. The movement of the moving plates 81 will cause the clamping plates 83 to be inserted into the clamping groove 10. At this time, the position of the output motor 4 can be fixed.

[0041] When the pull rod 16 drives the limiting plate 17 to be inserted into the limiting groove 18 at different positions, the adjusting block 3 can be positioned at different positions in the connecting shell 2, so that the output motor 4 can adjust the tension of the belt.

[0042] In summary, the motor connection structure of this backwashing bar screen cleaning equipment, through the coordinated use of the output motor 4, mounting slot 5, control hole 6, docking slot 7, and positioning component 8, allows the spring 82 to undergo elastic deformation, driving the two moving plates 81 back to their original positions. The movement of the moving plates 81 causes the clamping plate 83 to insert into the clamping slot 10, thus fixing the motor's position. This solves the problem that motors on backwashing bar screen cleaning equipment are usually fixed with multiple bolts, requiring consistent tightening torque for each bolt to avoid motor imbalance and increased installation complexity and difficulty.
