[0002] Mainstream sludge dewatering methods include filtration dewatering and centrifugal dewatering, which use filter presses and horizontal centrifuges respectively. The control cabinet is used to install the electrical components that control the operation of the filter press and horizontal centrifuge. Blockage of the filter cloth (or filter screen) in the filter press, sludge agglomeration in the centrifuge, and wear and jamming of the screw conveyor blades will all lead to large power fluctuations of the electrical components in the control cabinet and increased thermal expansion and contraction of the wires in the control cabinet. At the same time, due to the complex sludge dewatering environment (large humidity fluctuations and accompanied by particulate matter, etc.), this will cause the circuits in the control cabinet to age quickly. In order to ensure the stable operation of the control cabinet, the circuits in the control cabinet need to be frequently inspected and maintained. However, it is difficult to inspect the circuits arranged on the back of the mounting plate in the existing control cabinet, and the circuit inspection efficiency is low. Summary of the Invention

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1-10 The present invention provides a technical solution: a sludge dewatering system control cabinet that is easy to maintain, including a cabinet body 1, a door body 2 and a mounting plate 3. The door body 2 and the cabinet body 1 are hinged by a hinge. The mounting plate 3 is arranged on the inner side of the cabinet body 1 and is used to install electrical components; a guide rail 5 is fixedly installed in the cabinet body 1, and a slider 4 is slidably connected to the guide rail 5; the mounting plate 3 and the slider 4 are detachably plugged in, and the mounting plate 3 and the slider 4 can rotate relative to each other; a driving unit is provided in the cabinet body 1, and when the door body 2 is opened, the driving unit drives the slider 4 to drive the mounting plate 3 to move to the outside of the cabinet body 1 and drives the mounting plate 3 to rotate relative to the slider 4, so as to facilitate the maintenance of the circuit on the back of the mounting plate 3.

[0028] When the circuit in the control cabinet needs to be inspected, the door body 2 is opened. A sensor is installed on the door body 2. The sensor is used to control the drive unit. When the door body 2 is opened, the drive unit starts working; the drive unit drives the slider 4 to drive the mounting plate 3 to move toward the outside of the cabinet 1 on the guide rail 5. After moving a certain distance, the drive unit drives the mounting plate 3 to rotate relative to the slider 4, and 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 1, the circuit on the back of the mounting plate 3 can be clearly observed. At the same time, if the circuit is seriously aged, it can also be convenient for maintenance personnel to replace the circuit.

[0029] Specifically, such as Figure 2 、 Figure 3 as well as Figure 5 As 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.

[0030] 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.

[0031] 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.

[0032] 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 5 As shown, the first gear 10 is in a state of being out of contact with the first rack 11 in the initial position. The first gear 10 can mesh with the first rack 11 only after the slider 4 moves a certain distance outward. Therefore, the mounting plate 3 can be moved a certain distance outward before rotating. When the mounting plate 3 rotates a specified angle (45°-50°), the right end of the mounting plate 3 can be located as far as possible outside the cabinet 1, which can increase the observation space for maintenance personnel and also facilitate maintenance personnel to observe the aging of the circuit on the front of the mounting plate 3, which 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 toward the inside of 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.

[0033] Specifically, such as Figure 5 As shown, the linear drive unit includes an electric telescopic cylinder 12; the electric telescopic cylinder 12 is fixedly connected to the cabinet body 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 drives the slider 4 to move outward; after the maintenance is completed, the electric telescopic cylinder 12 drives the slider 4 to move toward the inside of the cabinet body 1.

[0034] Specifically, such as Figure 2 、 Figure 4 as well as Figure 6 As shown, a bracket 13 is fixedly connected to the slider 4, a pressure rod 14 is rotatably connected to the bracket 13, a second gear 15 is fixedly connected to the rotating shaft of the pressure rod 14, and a second rack 16 engaged with the second gear 15 is fixedly connected to the top of the guide rail 5; when the pressure rod 14 is rotated to a horizontal state, its top surface is flush with the top surface of the slider 4.

[0035] See Figure 4 and Figure 6When the second gear 15 and the second rack 16 are engaged, the pressure rod 14 can support and limit the mounting plate 3, and the mounting plate 3 can remain stable in the cabinet 1 to prevent the mounting plate 3 from shaking. When the slider 4 slides toward the outside of the cabinet 1, the slider 4 drives the bracket 13 and the pressure rod 14 to move outward synchronously. Under the action of the second rack 16, the second gear 15 drives the pressure rod 14 to rotate counterclockwise to Figure 6 In the state shown by the dotted line, the second gear 15 is disengaged from the second rack 16, the pressure rod 14 is in a horizontal state and the top surface is flush with the top surface of the slider 4; Figure 5 and Figure 10 When the mounting plate 3 rotates counterclockwise, its bottom surface and the top surface of the pressure rod 14 remain in contact with each other until the mounting plate 3 rotates to Figure 10 In the state shown, the pressure rod 14 supports the mounting plate 3, which can make the mounting plate 3 more stable during maintenance.

[0036] Specifically, such as Figure 1 、 Figure 7-Figure 9 As shown, a number of wire troughs 17 are fixedly installed on the side wall of the mounting plate 3, and the bottom end of the wire trough 17 is fixedly connected to the mounting block 18 by bolts, and the mounting block 18 is fixedly connected to the cover plate 19; the side wall of the cover plate 19 is fixedly connected to the support rod 20; the side wall of the wire trough 17 is rotatably connected to the limit block 21; the rotating shaft of the limit block 21 is provided with a torsion spring 24 for its reset; the limit block 21 is fixedly connected to the steel rope 22; a number of steel ropes 22 are fixedly connected to a sliding rod 23 at one end away from the limit block 21, and the sliding rod 23 is slidably connected to the mounting plate 3.

[0037] The electrical components in the cabinet 1 are installed between two adjacent wire ducts 17. The wires connecting the electrical components can pass through the wire ducts 17. The wire ducts 17 cooperate with the cover 19 to protect the wires. When installing the electrical components and connecting the wires, the mounting block 18 and the cover 19 are separated from the wire duct 17. After the electrical components and wires are installed, the mounting block 18 is installed to the bottom of the wire duct 17 and fixed with bolts. Then the cover 19 is installed on the mounting block 18 through the hinge shaft. The limit block 21 on the wire duct 17 can limit the support rod 20, so that the cover 19 covers the front end of the wire duct 17. When the control cabinet is repaired, the mounting plate 3 is moved to Figure 5After reaching the position shown by the dotted line, the maintenance personnel can toggle the slide bar 23, and the slide bar 23 can drive all the limit blocks 21 to rotate upward through the steel rope 22. After the limit block 21 rotates to disengage from the support rod 20, the cover 19 rotates downward under the action of gravity; all the cover plates 19 in the cabinet 1 can be opened at once, which can facilitate the maintenance personnel to observe the aging of the lines in the cable duct 17, and can further improve the maintenance efficiency of the lines in the control cabinet; after the maintenance is completed, the maintenance personnel only need to push the cover plate 19 upward to a state that it is in contact with the front end of the cable duct 17. At this time, the support rod 20 will cooperate with the limit block 21 to fix the cover plate 19 again.
