Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides an electrical control cabinet for electrical engineering automation, which solves the problems raised in the above background technique.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An electrical control cabinet for electrical engineering automation, including a control cabinet body for controlling the operation of electrical equipment, including: A cabinet door, which is slidably installed on the front side of the control cabinet body; A tooth block frame, which is fixedly installed at the bottom of the cabinet door; A gear set, which is rotatably installed at the bottom of the inner wall of the control cabinet, and the gear set meshes with the tooth block frame; A connecting tooth rod, which is slidably installed on the inner wall of the control cabinet, and the connecting tooth rod meshes with the gear set; A rotary knob rotatably installed at the rear side of the connecting rack A hollow plate slidably installed on the inner wall of the control cabinet for guiding and transferring air A fixing plate fixedly installed on the inner wall of the hollow plate A limiting block slidably installed on the inner wall of the fixing plate. A first spring is arranged between the limiting block and the fixing plate. The first spring drives the limiting block to reset and then limits the rotary knob A connecting button sleeved on the inner wall of the control cabinet A fan group slidably installed on the inner wall of the control cabinet for cooling and dissipating heat inside the control cabinet. When the connecting button is rotated downward, the fan group can be moved out

[0007] According to the above technical solution, a docking groove is formed on one side of the rotary knob close to the connecting button. By sliding the connecting button forward to make it fit with the docking groove, the rotary knob can be rotated at this time. The left side of the limiting block is set as an inclined surface. The connecting button contacts the inclined surface of the limiting block. At this time, the limiting block is squeezed and compresses the first spring, and restricts the rotary knob when finally resetting

[0008] According to the above technical solution, the ventilation device includes a heat exchange box, a sliding frame and a cooling plate. The heat exchange box is arranged on the inner wall of the control cabinet. The heat exchange box and the hollow plate are communicated through a telescopic pipe. The sliding frame is slidably installed on the inner wall of the hollow plate. The cooling plate is fixedly installed at the bottom of the sliding frame. The cooling plate and the hollow plate are communicated through a pipe. The fan group cools and dissipates heat inside the control cabinet. The generated air will be guided and transferred through the inside of the hollow plate, and finally enter the heat exchange box through the telescopic pipe for heat exchange. The air inside the hollow plate will also enter the cooling plate through the pipe to absorb heat from the bottom of the sliding frame Wherein, a support device for supporting the bottom when the hollow plate extends and a bundling device for arranging the wires inside the control cabinet are arranged inside the control cabinet

[0009] According to the above technical solution, the support device includes a chute plate, a sliding plate and a stop rod. The chute plate is fixedly installed at the bottom of the fixing plate. The sliding plate is fixedly installed on the inner wall of the control cabinet. The stop rod is fixedly installed on the inner wall of the control cabinet. The movement of the fixing plate drives the movement of the chute plate

[0010] According to the above technical solution, the support device further includes support feet, sliding buttons, connecting rods, and second springs. The support feet are rotatably installed on the inner wall of the chute plate, the sliding buttons are rotatably installed on the inner wall of the chute plate, one side of the connecting rod is rotatably installed on the left side of the support feet, the other side of the connecting rod is rotatably installed on the left side of the sliding buttons, and the second springs are arranged between the connecting rods and the chute plate. After the second springs are reset, they drive the sliding buttons to rotate. When the chute plate moves, it drives the support feet and the sliding buttons to move simultaneously. The sliding buttons move along the sliding plate. When the chute plate contacts the stop rod, at this time, the sliding buttons are disengaged from the sliding plate at the same time. At this time, the second springs are reset to drive the sliding buttons to rotate downward. The rotation of the sliding buttons drives the rotation of the connecting rods, and the rotation of the connecting rods drives the support feet to rotate downward.

[0011] According to the above technical solution, the support device further includes a control box, a sliding rod, a wire collecting board, and a limiting button. The control box is arranged on the inner wall of the sliding frame, the sliding rod is fixedly installed on the outer wall of the control cabinet, the wire collecting board is slidably installed on the circumferential surface of the sliding rod, and the limiting button is rotatably installed on the outer wall of the control cabinet. After the control box is installed, the wires it brings are arranged through the wire collecting board. When arranging, the restriction on the wire collecting board is released by rotating the limiting button, and then the wire collecting board is moved upward along the sliding rod. At this time, each wire is placed one by one.

[0012] The support device further includes a fixed pulley and a supporting rod. The fixed pulley is arranged on the inner wall of the control cabinet, the supporting rod is rotatably installed on the inner wall of the control cabinet. A rope is arranged between the chute plate and the side of the supporting rod close to the fixed pulley. The rope contacts the fixed pulley, and the other side of the supporting rod contacts the wire. When the chute plate moves forward, it pulls the rope, so that the supporting rod drives the other side to move the wire upward through the lever principle, and the reserved wire is pulled.

[0013] According to the above technical solution, the bundling device includes a hollow frame, a triangular frame, and a hollow cylinder. The hollow frame is fixedly installed on the outer wall of the control cabinet, the triangular frame is fixedly installed on the inner wall of the hollow frame, and the hollow cylinder is fixedly installed on the inner wall of the hollow frame. They are bundled by a wire bundling belt. At this time, all the wires are concentrated and placed in a cylindrical shape inside the hollow cylinder, that is, the wires of the control box contact the clamping rods.

[0014] According to the above technical solution, the bundling device further includes clamping rods, third springs, and clamping buttons. The clamping rods are slidably installed on the inner wall of the triangular frame, and the third springs are arranged between the triangular frame and the clamping rods. The third springs are arranged to drive the clamping rods to clamp the wires. The clamping buttons are rotatably installed on the surface of the hollow cylinder, and a first torsion spring is arranged between the clamping buttons and the hollow cylinder. The first torsion spring is arranged to drive the clamping buttons to reset. Due to the weight of the wires, the clamping rods move and compress the third springs at the same time. After placing at three positions, the third springs drive the clamping rods to reset and clamp the wires.

[0015] The present invention provides an electrical control cabinet for electrical engineering automation. It has the following beneficial effects: (1) In this invention, through the setting of the ventilation device, the inside of the control cabinet body is cooled and dissipated by the fan group. The generated wind will be guided and transmitted through the inside of the hollow plate, and finally enter the heat exchange box through the telescopic pipe for heat exchange. The wind inside the hollow plate will also enter the cooling plate through the pipe to absorb heat from the bottom of the sliding rack. By pulling the cabinet door to the left, the devices inside the control cabinet body can be pulled out as a whole. When operating inside the electrical control cabinet, sliding out the internal devices can reduce the contact risk between maintenance personnel and live parts and improve the safety of operation. When turning the connection button downward, the fan group can be moved out. When the fan group needs to be maintained, repaired or replaced, sliding it out can provide a more convenient operation space, enabling the staff to easily access the internal components for necessary maintenance work.

[0016] (2) In this invention, through the setting of the support device, when the whole device slides out, its weight may be heavy, and at this time, the bottom needs to be supported. At this time, by moving the fixed plate, the support feet are in contact with the ground, so as to support the bottom when the device slides out. Stable bottom support can prevent accidents such as tipping of the internal devices after they slide out and ensure the safety of the operators. After the control box is installed, the wires it brings are laid out through the wire collecting board. When laying out the wires of the control box, compared with the wires of the control box at other positions, the length of the wires reserved near the wire collecting board is shorter. This will lead to the situation that when the reserved wire length is insufficient or there is no appropriate slack, the wires may be pulled when the control box slides out, resulting in wire cracking. By driving the wires to move upward through the support rod, the reserved wires are pulled, so that the wires are extended.

[0017] (3) In this invention, through the setting of the bundling device, after the wires are laid out, they are bundled by the wire tying belt. At this time, all the wires are concentrated and placed in a cylindrical shape inside the hollow cylinder. Due to the weight of the wires, the clamping rod clamps the wires. Clamping can keep the bundled wires in a specific position, prevent them from shaking or moving, and ensure the stability of the wires. The bundled wires will contact the clamping button at this time. When the wires are strongly pulled, the clamping button will rotate and clamp the wires, so that greater force is required to pull the wires. When the wires are strongly pulled, clamping can play a certain protective role to prevent the wires from being overstretched or damaged. This is particularly important for protecting parts such as the insulation layer, conductor and joints of the wires, and helps to extend the service life of the wires.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 - 6 One embodiment of the present invention is: an electrical control cabinet for electrical engineering automation, comprising a control cabinet body 1, used for controlling the operation of electrical equipment, including: A cabinet door 2, the cabinet door 2 is slidably mounted on the front side of the control cabinet body 1; The gear block frame 3 is fixedly mounted on the bottom of the cabinet door 2; The gear set 4 is rotatably installed at the bottom of the inner wall of the control cabinet body 1, and the gear set 4 meshes with the tooth block frame 3; The connecting tooth rod 5 is slidably installed on the inner wall of the control cabinet body 1, and the connecting tooth rod 5 meshes with the gear set 4; The rotary knob 51 is rotatably installed at the rear side of the connecting tooth rod 5; The hollow plate 6 is slidably installed on the inner wall of the control cabinet body 1 and is used for guiding and transmitting wind; The fixing plate 7 is fixedly installed inside the hollow plate 6; The limiting block 8 is slidably installed inside the fixing plate 7. A first spring is arranged between the limiting block 8 and the fixing plate 7. After the limiting block 8 is driven by the first spring to reset, the rotary knob 51 is limited; The connecting button 9 is sleeved on the inner wall of the control cabinet body 1; The fan group 10 is slidably installed on the inner wall of the control cabinet body 1. The fan group 10 is used for cooling and dissipating heat inside the control cabinet body 1. When operating inside the electrical control cabinet, sliding out the internal device can reduce the contact risk between maintenance personnel and the live part and improve the safety of operation.

[0022] A docking groove is formed on one side of the rotary knob 51 close to the connecting button 9, so that the limiting button 9 can drive the rotary knob 51 to rotate. The left side of the limiting block 8 is set as an inclined surface. Through the arranged inclined surface, the limiting block 8 limits the rotary knob 51 after contacting it.

[0023] The ventilation device includes a heat exchange box 11, a sliding frame 12 and a cooling plate 13. The heat exchange box 11 is arranged on the inner wall of the control cabinet body 1. The heat exchange box 11 is communicated with the hollow plate 6 through a telescopic pipeline. The sliding frame 12 is slidably installed inside the hollow plate 6. The cooling plate 13 is fixedly installed at the bottom of the sliding frame 12. The cooling plate 13 is communicated with the hollow plate 6 through a pipeline. The generated wind will be guided and transmitted through the inside of the hollow plate 6 and finally enter the heat exchange box 11 through the telescopic pipeline for heat exchange. The wind inside the hollow plate 6 will also enter the cooling plate 13 through the pipeline to absorb heat from the bottom of the sliding frame 12.

[0024] During the operation of this embodiment, the control cabinet body 1 is cooled and dissipated heat by the fan group 10. The generated wind will be guided and transmitted through the inside of the hollow plate 6, and finally enter the heat exchange box 11 through the telescopic pipeline for heat exchange. The wind inside the hollow plate 6 will also enter the cooling plate 13 through the pipeline to absorb heat from the bottom of the sliding frame 12. By pulling the cabinet door 2 to the left, the tooth block frame 3 is driven to move. The movement of the tooth block frame 3 causes the gear group 4 to rotate clockwise. The clockwise rotation of the gear group 4 causes the connecting tooth rod 5 to move forward. The movement of the connecting tooth rod 5 drives the rotation button 51 to move. Before this, by sliding the connecting button 9 forward to make it fit with the docking groove, and then rotating the connecting button 9 upward, the connecting button 9 contacts the inclined surface of the limiting block 8. At this time, the limiting block 8 is squeezed and compresses the first spring, and restricts the rotation button 51 when finally reset. At this time, the rotation button 51 is driven to move by the connecting tooth rod 5. The movement of the rotation button 51 drives the fixing plate 7 to move. The movement of the fixing plate 7 drives the hollow plate 6 to move. The movement of the hollow plate 6 drives the sliding frame 12 to move, so that the devices inside the control cabinet body 1 are all pulled out. When operating inside the electrical control cabinet, sliding out the internal devices can reduce the contact risk between maintenance personnel and live parts and improve the safety of operation. When rotating the connecting button 9 downward, the fan group 10 can be removed. When the fan group 10 needs to be maintained, repaired or replaced, sliding it out can provide a more convenient operation space, enabling the staff to easily access the internal components for necessary maintenance work.

[0025] Please refer to Figures 1 - 9 , on the basis of the above embodiment, in another embodiment of the present invention, a support device for supporting the bottom of the hollow plate 6 when it extends out and a bundling device for arranging the wires inside the control cabinet body 1 are provided inside the control cabinet body 1. The support device includes a chute plate 20, a sliding plate 21 and a stop rod 22. The chute plate 20 is fixedly installed at the bottom of the fixing plate 7, the sliding plate 21 is fixedly installed on the inner wall of the control cabinet body 1, and the stop rod 22 is fixedly installed on the inner wall of the control cabinet body 1. When the whole device slides out, its weight may be heavy, and at this time, the bottom needs to be supported.

[0026] The support device further includes a support foot 23, a sliding button 24, a connecting rod 25 and a second spring 26. The support foot 23 is rotatably installed on the inner wall of the chute plate 20, the sliding button 24 is rotatably installed on the inner wall of the chute plate 20. One side of the connecting rod 25 is rotatably installed on the left side of the support foot 23, and the other side of the connecting rod 25 is rotatably installed on the left side of the sliding button 24. The second spring 26 is arranged between the connecting rod 25 and the chute plate 20. By setting the second spring 26 to drive the sliding button 24 to rotate after reset, stable bottom support can prevent accidents such as tipping of the internal device after it slides out and ensure the safety of the operator.

[0027] The supporting device also includes a control box 27, a slide bar 28, a wire collection plate 29 and a limit button 210. The control box 27 is arranged on the inner wall of the sliding frame 12, the slide bar 28 is fixedly installed on the outer wall of the control cabinet 1, the wire collection plate 29 is slidably installed on the circumferential surface of the slide bar 28, and the limit button 210 is rotatably installed on the outer wall of the control cabinet 1. The bundled lines are clearly marked and laid out on the wire collection plate 29. When maintenance or overhaul is required, the staff can quickly find the corresponding lines to improve work efficiency.

[0028] The supporting device also includes a fixed pulley 211 and a supporting rod 212. The fixed pulley 211 is arranged on the inner wall of the control cabinet 1, and the supporting rod 212 is rotatably installed on the inner wall of the control cabinet 1. A rope is arranged between the slide plate 20 and the side of the supporting rod 212 close to the fixed pulley 211. The rope is in contact with the fixed pulley 211, and the other side of the supporting rod 212 is in contact with the line to prevent tearing caused by dragging when the line length is insufficient or there is no suitable slack.

[0029] The bundling device includes a hollow frame 30, a tripod 31 and a hollow tube 32. The hollow frame 30 is fixedly installed on the outer wall of the control cabinet 1, the tripod 31 is fixedly installed on the inner wall of the hollow frame 30, and the hollow tube 32 is fixedly installed on the inner wall of the hollow frame 30. After the lines are laid out, they are bundled with cable ties. At this time, all the lines are concentrated and placed in a cylindrical shape inside the hollow tube 32.

[0030] The bundling device also includes a clamping rod 33, a No. 3 spring 34 and a locking button 35. The clamping rod 33 is slidably installed on the inner wall of the tripod 31. The No. 3 spring 34 is arranged between the tripod 31 and the clamping rod 33. The No. 3 spring 34 drives the clamping rod 33 to clamp the line. The locking button 35 is rotatably installed on the surface of the hollow tube 32. A No. 1 torsion spring is arranged between the locking button 35 and the hollow tube 32. The No. 1 torsion spring drives the locking button 35 to reset.

[0031] When this embodiment is working, when the entire device slides out, its weight may be relatively heavy, and at this time, the bottom needs to be supported. At this time, the fixing plate 7 moves to drive the sliding groove plate 20 to move. At this time, the second spring 26 is in a compressed state. The movement of the sliding groove plate 20 drives the support feet 23 and the sliding buttons 24 to move simultaneously. The sliding button 24 moves along the sliding plate 21. When the sliding groove plate 20 contacts the stop rod 22, at this time, the sliding button 24 simultaneously disengages from the sliding plate 21. At this time, the second spring 26 resets to drive the sliding button 24 to rotate downward. The rotation of the sliding button 24 drives the connecting rod 25 to rotate. The rotation of the connecting rod 25 drives the support feet 23 to rotate downward. The support feet 23 will eventually contact the ground, so as to support the bottom of the device when it slides out. Stable bottom support can prevent accidents such as the internal device tipping over after sliding out, ensuring the safety of the operator. After the control box 27 is installed, the wires it brings are arranged through the wire bundling board 29. When arranging, after releasing the restriction on the wire bundling board 29 by rotating the limit button 210, the wire bundling board 29 is moved upward along the sliding rod 28. At this time, each wire is placed one by one. The bundled wires have clear markings and layouts on the wire bundling board 29. When maintenance or repair is needed, the staff can quickly find the corresponding wires, improving work efficiency; When arranging the wires of the control box 27, compared with the wires of the control box 27 at other positions, the length of the wires of the control box 27 close to the wire bundling board 29 is shorter. This will cause the wires to be pulled and torn when the control box 27 slides out when the wire length is not reserved enough or there is no appropriate slack. At this time, the sliding groove plate 20 moves forward to pull the rope, so that the support rod 212 drives the other side to move the wire upward through the lever principle, so that the reserved wire is pulled, the wire is extended and its slack is increased. After arranging the wires, they are bundled with cable ties. At this time, all the wires are concentrated and placed in a cylindrical shape inside the hollow cylinder 32, that is, the wires of the control box 27 contact the clamping rod 33. The weight of the wires causes the clamping rod 33 to move and compress the third spring 34 at the same time. After placing them in three positions, the third spring 34 drives the clamping rod 33 to reset and clamp the wires. Clamping can keep the bundled wires in a specific position, preventing them from shaking or moving, and ensuring the stability of the wires. The bundled wires will contact the clamping button 35 at this time. When the wires are strongly pulled, the clamping button 35 will rotate and clamp the wires, so that the wires need greater force to be pulled. When the wires are strongly pulled, clamping can play a certain protective role to prevent the wires from being overstretched or damaged. This is particularly important for protecting the insulation layer, conductor and joints of the wires, and helps to extend the service life of the wires.

[0032] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
