Description

Technical Field

[0001] The present invention relates to the technical field of control cabinets, and particularly to a sludge dewatering system control cabinet that is convenient for maintenance. Background Technique

[0002] The mainstream sludge dewatering methods include filtration dewatering and centrifugal dewatering, using a filter press and a horizontal centrifuge respectively. The control cabinet is used to install electrical components for controlling the operation of the filter press and the horizontal centrifuge. Clogging of the filter cloth (or filter screen) in the filter press, sludge caking in the centrifuge, and wear and jamming of the spiral conveyor blades will all cause large changes in the power of the electrical components in the control cabinet, and the thermal expansion and contraction of the wires in the control cabinet will be aggravated. At the same time, due to the relatively complex sludge dewatering environment (large humidity changes and accompanied by particulate matter, etc.), this will cause the circuit in the control cabinet to age quickly. In order to ensure the stable operation of the control cabinet, the lines in the control cabinet need to be frequently maintained. However, it is difficult to maintain the lines arranged on the back of the mounting plate in the existing control cabinet, and the maintenance efficiency of the lines is low. Summary of the Invention

Detailed implementation manners

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a sludge dewatering system control cabinet convenient for maintenance, including a cabinet body 1, a door body 2 and a mounting plate 3. The door body 2 is hinged to the cabinet body 1 through a hinge. The mounting plate 3 is arranged inside the cabinet body 1 and is used for installing electrical components; a guide rail 5 is fixedly installed inside the cabinet body 1, and a slider 4 is slidably connected to the guide rail 5; the mounting plate 3 is detachably inserted into the slider 4, and the mounting plate 3 and the slider 4 can rotate relative to each other; a driving unit is arranged inside the cabinet body 1. When the door body 2 is opened, the driving unit drives the slider 4 to drive the mounting plate 3 to move outward relative to the cabinet body 1 and drives the mounting plate 3 to rotate relative to the slider 4, facilitating the maintenance of the circuits on the back of the mounting plate 3.

[0017] When it is necessary to maintain the circuits inside the control cabinet, open the door body 2. A sensor is installed on the door body 2, and the sensor is used to control the driving unit. When the door body 2 is opened, the driving unit starts to work; the driving unit drives the slider 4 to drive the mounting plate 3 to move outward on the guide rail 5 relative to the cabinet body 1. After moving a certain distance, the driving unit drives the mounting plate 3 to rotate relative to the slider 4. The right end of the mounting plate 3 rotates outward. After the mounting plate 3 rotates to be parallel to the right side wall of the cabinet body 1, the circuits located on the back of the mounting plate 3 can be clearly observed. At the same time, if there are severely aged circuits, it is also convenient for maintenance personnel to replace the circuits.

[0018] Specifically, as Figure 2 , Figure 3 and Figure 5As shown, the slider 4 is rotatably connected to a rotating shaft 6, and a clamping slot 7 is provided on the rotating shaft 6; the mounting plate 3 is slidably connected to a clamping block 8 in the vertical direction; and a reset spring 9 for resetting the clamping block 8 is fixedly connected to the clamping block 8.

[0019] When the mounting plate 3 is installed in the cabinet 1, the block 8 can be pushed toward the inside of the mounting plate 3 by toggling the cross bar 25 fixed on the block 8. At this time, the return spring 9 is in a compressed state, and then the mounting plate 3 is pushed to move the block 8 into the slot 7. Then the cross bar 25 is released, and the block 8 can be inserted into the deep end of the slot 7 under the elastic force of the return spring 9. At this time, the mounting plate 3 is relatively fixed to the rotating shaft 6, and the rotating shaft 6 is set at the left end of the slider 4. The cross bar 25 plays a guiding role in the sliding of the block 8; Figure 5 As shown, when the driving unit drives the mounting plate 3 to rotate relative to the slider 4, the mounting plate 3 rotates clockwise. At this time, the mounting plate 3 and the door body 2 are in a relative state. The construction personnel can stand between the mounting plate 3 and the door body 2 to observe the aging of the line on the back of the mounting plate 3. At the same time, they can also stand in front of the mounting plate 3 to observe the aging of the line on the front of the mounting plate 3, which can greatly improve the maintenance efficiency of the control cabinet.

[0020] Specifically, such as Figure 2 、 Figure 3 and Figure 5 As shown, the drive unit includes a first gear 10, a first rack 11 and a linear drive part; the first gear 10 is fixedly connected to the rotating shaft 6, the first rack 11 is fixedly connected to the cabinet 1 and can engage with the first gear 10; the linear drive part is used to drive the slider 4 to slide on the guide rail 5.

[0021] When the door 2 is opened and the control cabinet needs to be inspected, the linear drive mechanism drives the driving slide 4 to move toward the outside of the cabinet 1 on the guide rail 5. The slide 4 drives the mounting plate 3 to move outward synchronously through the rotating shaft 6. The rotating shaft 6 drives the first gear 10 to move synchronously. When the first gear 10 moves to engage with the first rack 11, the slide 4 continues to move outward. The first rack 11 drives the first gear 10, the rotating shaft 6 and the mounting plate 3 to rotate clockwise until the mounting plate 3 rotates to Figure 5 The state shown by the dotted line; Figure 5As shown, the first gear 10 is in a state of being disengaged from the first rack 11 at the initial position. After the slider 4 moves outward a certain distance, the first gear 10 can mesh with the first rack 11. Therefore, the mounting plate 3 can move outward a certain distance and then rotate. When the mounting plate 3 rotates by a specified angle (45° - 50°), the right end of the mounting plate 3 can be located outside the cabinet 1 as much as possible, which can increase the observation space for maintenance personnel and also facilitate the maintenance personnel to observe the circuit aging condition on the front of the mounting plate 3, and can greatly improve the maintenance efficiency of the control cabinet; after the maintenance is completed, the linear drive mechanism drives the slider 4 to move inward the cabinet 1, and the mounting plate 3 first rotates to a state parallel to the back of the cabinet 1 and then moves back to the initial position.

[0022] Specifically, as Figure 5 shown, the linear drive part includes an electric telescopic cylinder 12; the electric telescopic cylinder 12 is fixedly connected to the cabinet 1 and the output end is fixedly connected to the slider 4; the sensor on the door body 2 is electrically connected to the electric telescopic cylinder 12. When the door body 2 is opened, the electric telescopic cylinder 12 starts to work, and the electric telescopic cylinder 12 drives the slider 4 to move outward; after the maintenance is completed, the electric telescopic cylinder 12 drives the slider 4 to move inward the cabinet 1.

[0023] Specifically, as Figure 2 、 Figure 4 and Figure 6 shown, a bracket 13 is fixedly connected to the slider 4, a pressure lever 14 is rotatably connected to the bracket 13, a second gear 15 is fixedly connected to the rotating shaft of the pressure lever 14, and a second rack 16 meshing with the second gear 15 is fixedly connected to the top of the guide rail 5; when the pressure lever 14 rotates to the horizontal state, its top surface is flush with the top surface of the slider 4.

[0024] Refer to Figure 4 and Figure 6 In the initial state, the top end of the pressure lever 14 contacts the front surface of the mounting plate 3. When the electric telescopic cylinder 12 does not work, the slider 4 and the guide rail 5 are in a relatively fixed state. At this time, under the meshing action of the second gear 15 and the second rack 16, the pressure lever 14 can support and limit the mounting plate 3, and the mounting plate 3 can remain stable in the cabinet 1 and can avoid the mounting plate 3 from shaking; when the slider 4 slides outward the cabinet 1, the slider 4 drives the bracket 13 and the pressure lever 14 to move outward synchronously. Under the action of the second rack 16, the second gear 15 drives the pressure lever 14 to rotate counterclockwise to Figure 6 the state shown by the dotted line. At this time, the second gear 15 is disengaged from the second rack 16, and the pressure lever 14 is in the horizontal state and its top surface is flush with the top surface of the slider 4; referring to Figure 5 and Figure 10 , when the mounting plate 3 rotates counterclockwise, its bottom surface remains in contact with the top surface of the pressure lever 14 until the mounting plate 3 rotates to Figure 10In the shown state, the pressure bar 14 supports the mounting plate 3, enabling the mounting plate 3 to be more stable during maintenance.

[0025] Specifically, as Figure 1 , Figures 7 - 9 shown, a plurality of wire grooves 17 are fixedly installed on the side wall of the mounting plate 3. The bottom end of the wire groove 17 is fixedly connected with a mounting block 18 through bolts, and a cover plate 19 is fixedly connected to the mounting block 18; a support rod 20 is fixedly connected to the side wall of the cover plate 19; a limiting block 21 is rotatably connected to the side wall of the wire groove 17; a torsion spring 24 for its reset is sleeved on the rotating shaft of the limiting block 21; a steel wire rope 22 is fixedly connected to the limiting block 21; one ends of a plurality of steel wire ropes 22 far away from the limiting block 21 are fixedly connected together to form a sliding rod 23, and the sliding rod 23 is slidably connected with the mounting plate 3.

[0026] The electrical components in the cabinet body 1 are installed in the middle of two adjacent wire grooves 17. The wires connecting the electrical components can pass through the wire grooves 17, and the wire grooves 17 and the cover plate 19 can protect the wires; when installing the electrical components and connecting the wires, the mounting block 18 and the cover plate 19 are in a state of being separated from the wire groove 17; after the installation of the electrical components and the wires is completed, the mounting block 18 is installed at the bottom of the wire groove 17 and fixed by bolts; then the cover plate 19 is installed on the mounting block 18 through a hinge shaft. The limiting block 21 on the wire groove 17 can limit the support rod 20, so that the cover plate 19 covers the front end of the wire groove 17; when maintaining the control cabinet, after the mounting plate 3 moves to the Figure 5 position shown by the dotted line, the maintenance personnel can move the sliding rod 23. The sliding rod 23 can drive all the limiting blocks 21 to rotate upward through the steel wire ropes 22. After the limiting blocks 21 rotate to be separated from the support rod 20, the cover plate 19 rotates downward under the action of gravity; all the cover plates 19 in the cabinet body 1 can be opened all at once, which is convenient for the maintenance personnel to observe the aging condition of the wires in the wire grooves 17 and can further improve the maintenance efficiency of the wires in the control cabinet; after the maintenance is completed, the maintenance personnel only need to push the cover plate 19 upward to a state where it fits with the front end of the wire groove 17. At this time, the support rod 20 will cooperate with the limiting block 21 to fix the cover plate 19 again.
