Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an electrical control cabinet for electrical engineering automation, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrical control cabinet for electrical engineering automation, comprising a control cabinet body for controlling the operation of electrical equipment, including: Cabinet door, which is slidably mounted on the front side of the control cabinet; A toothed block frame, which is fixedly installed at the bottom of the cabinet door; A gear set, which is rotatably mounted on the bottom of the inner wall of the control cabinet, and meshes with a gear block frame; A connecting rack is slidably mounted on the inner wall of the control cabinet, and the connecting rack meshes with a gear set; A rotary knob, which is rotatably mounted on the rear side of the connecting gear; A hollow plate, which is slidably installed on the inner wall of the control cabinet, is used to guide and transmit air. A fixing plate is fixedly installed on the inner wall of the hollow plate; A limiting block is slidably installed on the inner wall of the fixed plate. A first spring is provided between the limiting block and the fixed plate. The first spring drives the limiting block to reset and then limits the rotation knob. A connecting button, which is sleeved on the inner wall of the control cabinet; The fan assembly is slidably mounted on the inner wall of the control cabinet. The fan assembly is used to cool and dissipate heat inside the control cabinet. The fan assembly can be moved out when the connecting button is turned downwards.

[0007] According to the above technical solution, the rotating button has a mating groove on the side near the connecting button. By sliding the connecting button forward, it fits into the mating groove, and the connecting button can be rotated. The left side of the limiting block is set as an inclined surface, and the connecting button contacts the inclined surface of the limiting block. At this time, the limiting block is squeezed and compresses the No. 1 spring, and restricts the rotating button during the final reset.

[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 installed on the inner wall of the control cabinet. The heat exchange box is connected to the hollow plate 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 is connected to the hollow plate through a pipe. The fan group cools and dissipates heat inside the control cabinet. The air generated is guided and transmitted through the inside of the hollow plate and finally enters the heat exchange box through the telescopic pipe for heat exchange. The air inside the hollow plate also enters the cooling plate through the pipe to absorb heat from the bottom of the sliding frame. The control cabinet is equipped with a support device for supporting the bottom of the hollow plate when it extends, and a bundling device for organizing the wires inside the control cabinet.

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

[0010] According to the above technical solution, the support device further includes a support foot, a sliding button, a connecting rod, and a second spring. The support foot is rotatably mounted on the inner wall of the slide plate, and the sliding button is rotatably mounted on the inner wall of the slide plate. One side of the connecting rod is rotatably mounted on the left side of the support foot, and the other side of the connecting rod is rotatably mounted on the left side of the sliding button. The second spring is disposed between the connecting rod and the slide plate. After the second spring is reset, it drives the sliding button to rotate. The movement of the slide plate drives the support foot and the sliding button to move simultaneously. The sliding button moves along the slide plate. When the slide plate contacts the stop rod, the sliding button simultaneously disengages from the slide plate. At this time, the second spring resets and drives the sliding button to rotate downward. The rotation of the sliding button drives the connecting rod to rotate, and the rotation of the connecting rod drives the support foot to rotate downward.

[0011] According to the above technical solution, the support device further includes a control box, a sliding rod, a cable tray, and a limit button. The control box is installed on the inner wall of the sliding frame, the sliding rod is fixedly installed on the outer wall of the control cabinet, the cable tray is slidably installed on the circumferential surface of the sliding rod, and the limit button is rotatably installed on the outer wall of the control cabinet. After the control box is installed, the cables it carries are laid out through the cable tray. When arranging the cables, the cable tray is moved upward along the sliding rod by rotating the limit button to release the restriction on the cable tray, and each cable is placed accordingly.

[0012] The support device also includes a fixed pulley and a support rod. The fixed pulley is installed on the inner wall of the control cabinet, and the support rod is rotatably installed on the inner wall of the control cabinet. A rope is provided between the slide plate and the side of the support rod near the fixed pulley. The rope is in contact with the fixed pulley, and the other side of the support rod is in contact with the wiring. By moving the slide plate forward and pulling the rope, the support rod, through the lever principle, causes the other side to move the wiring upward, so that the reserved wiring is pulled.

[0013] According to the above technical solution, the bundling device includes a hollow frame, a tripod, and a hollow cylinder. The hollow frame is fixedly installed on the outer wall of the control cabinet, the tripod 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. The hollow cylinder is bundled together with a cable tie. 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 are in contact with the clamping rod.

[0014] According to the above technical solution, the clustering device further includes a clamping rod, a No. 3 spring, and a locking button. The clamping rod is slidably installed on the inner wall of the tripod. The No. 3 spring is disposed between the tripod and the clamping rod. The No. 3 spring drives the clamping rod to clamp the line. The locking button is rotatably installed on the surface of the hollow cylinder. A No. 1 torsion spring is disposed between the locking button and the hollow cylinder. The No. 1 torsion spring drives the locking button to reset. The weight of the line causes the clamping rod to move and compress the No. 3 spring. After the line is placed in all three positions, the No. 3 spring drives the clamping rod to reset and clamp the line.

[0015] This invention provides an electrical control cabinet for electrical engineering automation. It has the following advantages: (1) In this invention, the ventilation device is set up and the fan group cools and dissipates heat inside the control cabinet. The air generated is guided and transmitted through the hollow plate and finally enters the heat exchange box through the telescopic pipe for heat exchange. The air inside the hollow plate also enters the cooling plate through the pipe to absorb heat at the bottom of the sliding frame. By pulling the cabinet door to the left, the entire device inside the control cabinet is pulled out. When operating inside the electrical control cabinet, sliding out the internal device can reduce the risk of contact between maintenance personnel and live parts and improve the safety of operation. When the connection button is turned down, the fan group can be moved out. When the fan group needs maintenance, repair or replacement, sliding it out can provide more convenient operating space, so that the staff can easily access the internal components and perform necessary maintenance work.

[0016] (2) In this invention, by setting up a support device, when the entire device slides out, its weight may be relatively heavy, and the bottom needs to be supported. At this time, the support foot is made to contact the ground after the fixed plate is moved, so that the bottom of the device is supported when it slides out. The stable bottom support can prevent the internal device from tipping over or other accidents after sliding out, and ensure the safety of the operator. After the control box is installed, its wiring is laid out through the hub plate. When laying out the wiring of the control box, the wiring of the control box near the hub plate is shorter than that of the control box wiring in other positions. This will cause the wiring to be pulled and torn when the control box slides out if the wiring length is insufficient or there is no appropriate slack. The support rod drives the wiring upward, so that the reserved wiring is pulled and the wiring is extended.

[0017] (3) In this invention, after the wiring is laid out, the wiring is bundled with a cable tie. At this time, all the wiring is concentrated and placed in a cylindrical shape inside the hollow cylinder. The weight of the wiring causes the clamping rod to clamp the wiring. The clamping can keep the bundled wiring in a specific position, prevent it from shaking or moving, and ensure the stability of the wiring. The bundled wiring will then contact the locking button. When the wiring is pulled strongly, the locking button will rotate and lock the wiring, so that the wiring needs more force to be pulled. When the wiring is pulled strongly, the locking can play a certain protective role, preventing the wiring from being overstretched or damaged. This is especially important for protecting the insulation layer, conductor and connector of the wiring, and helps to extend the service life of the wiring. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-6 One embodiment of the present invention is: an electrical control cabinet for electrical engineering automation, including a control cabinet body 1, used for controlling the operation of electrical equipment, comprising: Cabinet door 2 is slidably installed on the front side of control cabinet 1; Tooth block frame 3 is fixedly installed at the bottom of cabinet door 2; Gear set 4 is rotatably mounted on the bottom of the inner wall of control cabinet 1, and gear set 4 meshes with gear block frame 3; Connecting rack 5 is slidably installed on the inner wall of control cabinet 1, and connecting rack 5 meshes with gear set 4; Rotate knob 51, which is rotatably mounted on the rear side of connecting gear 5; Hollow plate 6 is slidably installed on the inner wall of control cabinet 1 to guide and transmit air. Fixing plate 7 is fixedly installed on the inner wall of hollow plate 6; Limiting block 8 is slidably installed on the inner wall of fixed plate 7. A first spring is provided between limiting block 8 and fixed plate 7. After the first spring drives limiting block 8 to reset, it limits the rotation knob 51. Connecting button 9, which is sleeved on the inner wall of control cabinet 1; Fan assembly 10 is slidably mounted on the inner wall of control cabinet 1. Fan assembly 10 is used to cool and dissipate heat inside control cabinet 1. When operating inside the electrical control cabinet, sliding out the internal device can reduce the risk of contact between maintenance personnel and live parts and improve the safety of operation.

[0022] The rotating knob 51 has a mating groove on the side near the connecting knob 9, so that the limiting knob 9 can drive the rotating knob 51 to rotate. The left side of the limiting block 8 is set as an inclined surface, which limits the limiting block 8 after it comes into contact with the rotating knob 51.

[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 installed on the inner wall of the control cabinet 1. The heat exchange box 11 is connected to the hollow plate 6 through a telescopic pipe. The sliding frame 12 is slidably installed on the inner wall of the hollow plate 6. The cooling plate 13 is fixedly installed at the bottom of the sliding frame 12. The cooling plate 13 is connected to the hollow plate 6 through a pipe. The air generated by the cooling plate 13 is guided and transmitted through the interior of the hollow plate 6, and finally enters the heat exchange box 11 through the telescopic pipe for heat exchange. The air inside the hollow plate 6 also enters the cooling plate 13 through the pipe to absorb heat from the bottom of the sliding frame 12.

[0024] In this embodiment, the fan assembly 10 cools the inside of the control cabinet 1. The generated airflow is guided through the hollow plate 6 and finally enters the heat exchange box 11 through the telescopic pipe for heat exchange. The airflow inside the hollow plate 6 also enters the cooling plate 13 through the pipe to absorb heat from the bottom of the sliding frame 12. Pulling the cabinet door 2 to the left moves the gear block frame 3, causing the gear set 4 to rotate clockwise. The clockwise rotation of the gear set 4 causes the connecting gear 5 to move forward, which in turn moves the rotating knob 51. Before this, the connecting knob 9 is slid forward to fit into the docking groove. At this time, rotating the connecting knob 9 upward causes the connecting knob 9 to contact the inclined surface of the limiting block 8, at which point the limiting block 8 is compressed. The first spring is compressed, and the rotating knob 51 is restricted during the final reset. At this time, the rotating knob 51 is moved by the connecting gear 5. The movement of the rotating knob 51 moves the fixed plate 7, which in turn moves the hollow plate 6. The movement of the hollow plate 6 moves the sliding frame 12, so that the entire device inside the control cabinet 1 is pulled out. When operating inside the electrical control cabinet, sliding out the internal device can reduce the risk of contact between maintenance personnel and live parts and improve the safety of operation. When the connecting knob 9 is turned down, the fan assembly 10 can be moved out. When the fan assembly 10 needs maintenance, repair or replacement, sliding it out can provide more convenient operating space, allowing the staff to easily access the internal components and perform necessary maintenance work.

[0025] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the control cabinet 1 is provided with a support device for supporting the bottom of the hollow plate 6 when it extends and a bundling device for organizing the wires inside the control cabinet 1. The support device includes a slide plate 20, a sliding plate 21 and a stop rod 22. The slide plate 20 is fixedly installed at the bottom of the fixed plate 7, the sliding plate 21 is fixedly installed on the inner wall of the control cabinet 1, and the stop rod 22 is fixedly installed on the inner wall of the control cabinet 1. When the entire device slides out, its weight may be relatively heavy, so the bottom needs to be supported at this time.

[0026] The support device also includes a support foot 23, a sliding button 24, a connecting rod 25, and a second spring 26. The support foot 23 is rotatably mounted on the inner wall of the slide plate 20, the sliding button 24 is rotatably mounted on the inner wall of the slide plate 20, one side of the connecting rod 25 is rotatably mounted on the left side of the support foot 23, and the other side of the connecting rod 25 is rotatably mounted on the left side of the sliding button 24. The second spring 26 is located between the connecting rod 25 and the slide plate 20. After the second spring 26 is reset, it drives the sliding button 24 to rotate. The stable bottom support can prevent the internal device from tipping over or other accidents after sliding out, ensuring the safety of the operator.

[0027] The support device also includes a control box 27, a slide bar 28, a hub plate 29, and a limit button 210. The control box 27 is installed 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 hub 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 have clear markings and layouts on the hub plate 29. When maintenance or repair is required, staff can quickly find the corresponding lines, improving work efficiency.

[0028] The support device also includes a fixed pulley 211 and a support rod 212. The fixed pulley 211 is installed on the inner wall of the control cabinet 1, and the support rod 212 is rotatably installed on the inner wall of the control cabinet 1. A rope is provided between the slide plate 20 and the side of the support rod 212 near the fixed pulley 211. The rope is in contact with the fixed pulley 211, and the other side of the support rod 212 is in contact with the line to prevent the line from being pulled and torn when the length is insufficient or there is no suitable slack.

[0029] The bundling device includes a hollow frame 30, a tripod 31, and a hollow cylinder 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 cylinder 32 is fixedly installed on the inner wall of the hollow frame 30. After the wiring is laid out, it is bundled with cable ties. At this time, all the wiring is concentrated and placed in a cylindrical shape inside the hollow cylinder 32.

[0030] The clustering device also includes a clamping rod 33, a third spring 34, and a locking button 35. The clamping rod 33 is slidably mounted on the inner wall of the tripod 31. The third spring 34 is located between the tripod 31 and the clamping rod 33. The clamping rod 33 is driven by the third spring 34 to clamp the line. The locking button 35 is rotatably mounted on the surface of the hollow cylinder 32. A first torsion spring is provided between the locking button 35 and the hollow cylinder 32. The locking button 35 is reset by the first torsion spring.

[0031] In this embodiment, during the sliding out of the entire device, due to its potentially heavy weight, bottom support is required. At this time, the fixed plate 7 moves, causing the sliding plate 20 to move. The second spring 26 is compressed. The movement of the sliding plate 20 causes the support foot 23 and the sliding button 24 to move simultaneously. The sliding button 24 moves along the sliding plate 21. When the sliding plate 20 contacts the stop rod 22, the sliding button 24 simultaneously disengages from the sliding plate 21. The second spring 26 then resets, causing the sliding button 24 to rotate downwards. The rotation of the sliding button 24 causes the connecting rod 25 to rotate, which in turn causes the support foot 23 to rotate downwards. The support foot 23 eventually... Contact with the ground provides support to the bottom of the device as it slides out. Stable bottom support prevents the internal device from tipping over or other accidents after sliding out, ensuring the safety of operators. After the control box 27 is installed, its wiring is laid out through the hub plate 29. When arranging the wiring, the limit button 210 is turned to release the restriction on the hub plate 29 and then the hub plate 29 is moved upward along the slide rod 28. At this time, each wire is placed in turn. The bundled wiring has clear markings and layout on the hub plate 29. When maintenance or repair is required, the staff can quickly find the corresponding wiring, improving work efficiency. When laying out the wiring in the control box 27, the wiring in the control box 27 near the hub plate 29 is shorter than that in other control boxes 27. This can lead to the wiring being pulled and torn when the control box 27 slides out if the wiring length is insufficient or there is no proper slack. In this case, the sliding plate 20 moves forward and pulls the rope, causing the support rod 212 to move the wiring upward through leverage, thus stretching the reserved wiring and increasing its slack. After the wiring is laid out, it is bundled with cable ties. At this point, all the wiring is gathered and placed in a cylindrical shape inside the hollow cylinder 32, that is, the wiring of the control box 27 is connected to the clamping rod 33. The weight of the wire causes the clamping rod 33 to move while compressing the third spring 34. After all three positions are reached, the third spring 34 drives the clamping rod 33 to reset and clamp the wire. Clamping keeps the bundled wire in a specific position, preventing it from shaking or moving and ensuring its stability. The bundled wire then contacts the locking button 35. When the wire is pulled strongly, the locking button 35 rotates and locks the wire, requiring more force to pull it. When the wire is subjected to strong pulling, the locking provides some protection, preventing the wire from being overstretched or damaged. This is especially important for protecting the insulation layer, conductor, and connectors of the wire, and helps extend the service life of the wire.

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