[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The embodiment of the present application discloses a split type low voltage reactive power compensation cabinet. Figure 1-Figure 4 A split low-voltage reactive compensation cabinet comprises a cabinet body 1, a cabinet door 2 arranged on the cabinet body 1 and a heat dissipation device. The cabinet body 1 is provided with a plurality of heat dissipation holes 3; the heat dissipation device adopts an electric fan to dissipate heat in the cabinet body 1. In this embodiment, the components in the cabinet body 1 are all split, that is, there is no interference between the components. If maintenance is required, only the corresponding components need to be repaired. The heat dissipation holes 3 are arranged in a plurality and the heat dissipation holes 3 located at the outermost periphery are presented in a rectangular shape.

[0021] It also includes a wiping device for cleaning multiple heat dissipation holes 3 at the same time; the wiping device includes a cleaning box 4 lifted and arranged on the inner wall of the cabinet 1, a cleaning plate 5 slidably arranged in the cleaning box 4, a cleaning piece 6 detachably arranged on the cleaning plate 5, a control piece for controlling the movement of the cleaning plate 5, an auxiliary mechanism for assisting the cleaning piece 6 to clean the heat dissipation holes 3, and an adjusting mechanism for judging whether the cleaning piece 6 has cleaned all the heat dissipation holes 3, the auxiliary mechanism includes an auxiliary box 7 lifted and arranged on the outer wall of the cabinet 1, a spray component for spraying alcohol on the multiple heat dissipation holes 3, and a protective component for reducing alcohol volatilization; the lifting of the cleaning box 4 and the auxiliary box 7 is achieved by an electric push rod. In this embodiment, since the cleaning time is short, the cleaning box 4 and the auxiliary box 7 cover all the heat dissipation holes 3. Of course, the multiple heat dissipation holes 3 can also be divided into two groups, that is, the heat dissipation holes 3 are cleaned twice.

[0022] The cleaning box 4 and the auxiliary box 7 are both opened on the side facing the cabinet 1, and the side wall of the opening of the cleaning box 4 is in contact with the inner wall of the cabinet 1, and the outer wall of the auxiliary box 7 is in contact with the outer wall of the cabinet 1; the spray assembly adopts a nozzle to target multiple heat dissipation holes 3, and the nozzle appears mist when spraying alcohol, thereby ensuring that alcohol exists in multiple heat dissipation holes 3. At this time, the cleaning piece 6 is in close contact with the inner wall of the cabinet 1, reducing the alcohol from volatilizing into the cabinet 1, and the auxiliary box 7 is also in a sealed state with the cabinet 1, further reducing the probability of alcohol volatilization; the cleaning piece 6 is squeezed toward the heat dissipation hole 3 by the control part and the cleaning piece 6 is sprayed into the cabinet 1. The cleaning member 6 is deformed toward the heat dissipation hole 3. In this embodiment, a sponge is used for the cleaning member 6. When the sponge is squeezed by the control member, the sponge part enters into the heat dissipation hole 3. In this embodiment, it is set that the cleaning member 6 can completely enter into the heat dissipation hole 3. At this time, alcohol can be sprayed on the heat dissipation hole 3. The alcohol enters into the heat dissipation hole 3 and is partially adsorbed by the cleaning member 6. At this time, the control member is used to reciprocate the cleaning member 6. During this process, the cleaning member 6 will not slip out of the heat dissipation hole 3 to avoid alcohol volatilization. Under the mutual cooperation of the cleaning member 6 and the alcohol, the cleaning effect of the heat dissipation hole 3 is achieved.

[0023] The protective component includes an isolation member 8, a winding portion for controlling the movement of the adsorption member, and a cooling portion for lowering the isolation member 8; the isolation member 8 covers the multiple heat dissipation holes 3, and the winding portion and the cooling portion are both located in the auxiliary box 7. In this embodiment, the isolation member 8 can be made of a film, or a material with good isolation effect can also be used; the winding box includes two winding rollers 9, two winding motors, four winding ropes 10 and a plurality of guide rollers 11 for attaching the isolation member 8 to the outer wall of the cabinet 1. The winding roller 9 is rotatably arranged in the auxiliary box 7 and the axial direction is perpendicular to the movement direction of the isolation member 8. The winding motor is arranged on the outer wall of the auxiliary box 7. The four winding ropes 10 are respectively connected to the four corners of the isolation member 8. Fixedly connected, four winding ropes 10 are arranged in two groups, each group of winding ropes 10 is fixedly connected to the outer wall of the same winding roller 9, the guide roller 11 is rotatably arranged on the auxiliary box 7, and the axial direction of the guide roller 11 is arranged parallel to the axial direction of the winding roller 9; the two winding motors respectively control the rotation of the winding roller 9 at the same frequency, and the size between the two winding ropes 10 in the same group is larger than the size occupied by the heat dissipation hole 3, that is, the winding rope 10 will not interfere with the heat dissipation hole 3. When cleaning the heat dissipation hole 3, it is necessary to control the isolation member 8 to move to the position covering the heat dissipation hole 3, and the isolation member 8 fits the outer wall of the cabinet 1, thereby further reducing the volatilization of alcohol and improving the cleaning efficiency.

[0024] The cooling part includes a cooling box 12, ice bars 13 arranged in the cooling box 12, and an identification group for identifying the consumption status of the ice bars 13. The cooling box 12 is arranged in parallel with the guide roller 11 in the length direction. The cooling box 12 is arranged in a U-shape. The isolation piece 8 is hollow from the cooling box 12 and the isolation piece 8 is fitted with the cooling outer wall. One end of the cooling box 12 is opened by bolts. The ice bars 13 are placed in the cooling box 12 by the staff. The length dimension of the cooling box 12 is adapted to the width dimension of the isolation piece 8. When the temperature in the environment is lowered, the volatilization of alcohol is lower. The cooling box 12 is mainly used to cool the isolation piece 8.

[0025] The cooling box 12 includes a placement cavity 14 and an identification cavity 15 for placing the ice bar 13. The volume of the placement cavity 14 is smaller than that of the identification cavity 15. The identification group includes a floating block 16, a floating rod 17, a first proximity switch 18 and a buzzer 19. The floating block 16 is floatingly arranged in the identification cavity 15. The floating rod 17 is fixedly connected to the upper surface of the floating block 16. The identification cavity 15 is provided with a floating hole 20 adapted to the sliding of the floating rod 17. The top of the floating rod 17 passes through the floating hole 20. The first proximity switch 18 is arranged above the outer wall of the identification cavity 15. When the top of the floating rod 17 abuts against the first proximity switch 18, the buzzer 19 sounds an alarm. First, the ice bar 13 is placed in the placement cavity 14. The ice bar 13 is adapted to the placement cavity 14. The cooling box 12 is in a horizontal state. When the ice bar 13 melts, The melted water enters the identification chamber 15, and the floating block 16 is made of a material with high buoyancy. As the water enters the identification chamber 15, the floating block 16 continuously floats up, and the floating rod 17 also moves. In this embodiment, it is set that when the identification chamber 15 is filled with water, the floating rod 17 abuts against the first proximity switch 18, and the first proximity switch 18 is connected to the buzzer 19 through the control of the PLC controller. At this time, the buzzer 19 sounds an alarm. Although the ice bar 13 is not completely melted at this moment, its cooling efficiency has been reduced, and the staff needs to replace the ice bar 13; as the isolation member 8 is pulled toward the heat dissipation hole 3, the isolation member 8 passes through the middle of the cooling box 12, and the isolation member 8 exchanges heat with the ice bar 13 in the cooling box 12, so that the temperature of the isolation member 8 is reduced, which is beneficial to reduce the volatilization of alcohol.

[0026] The adjusting mechanism comprises a bracket 21 moving along the length direction of the auxiliary box 7, a slide plate 22 slidably arranged on the bracket 21, a slide cylinder 23 slidably arranged on the slide plate 22, a detection rod 24 elastically arranged in the slide cylinder 23, a reciprocating component for restoring the position of the slide cylinder 23, an identification component for identifying that the cleaning member 6 has not entered the isolation hole, and an operating component for processing the adsorption member. The slide plate 22 moves along the length direction of the auxiliary box 7, the slide cylinder 23 moves toward the heat dissipation hole 3, the movement of the bracket 21 in the auxiliary box 7, the movement of the slide plate 22 in the bracket The movement on the frame 21 and the movement of the slide 23 on the slide 22 are both achieved by an electric push rod. A sliding hole is provided inside the slide 23. A limiting block 25 is fixedly connected to the side wall of the detection rod 24. A limiting groove 26 is provided on the side wall of the sliding hole. The limiting block 25 slides in the limiting groove 26. A spring 27 is fixedly connected between one side of the limiting block 25 and the corresponding end of the limiting groove 26, so that the detection rod 24 is elastically set in the slide 23. In the initial state, the end of the detection rod 24 is located outside the slide 23, and the bracket 21 is also located away from the heat dissipation hole 3.

[0027] Before spraying alcohol on the heat dissipation holes 3, it is necessary to detect whether the cleaning piece 6 is normally squeezed into the heat dissipation holes 3. Since dust will also adhere to the cleaning piece 6 during the cleaning process, although the alcohol will evaporate later, the dust will also affect the performance of the cleaning piece 6, such as making the cleaning piece 6 harden. If the cleaning piece 6 hardens, it will affect the cleaning piece 6 from entering the heat dissipation holes 3. Therefore, it is necessary to detect whether the cleaning piece 6 enters the heat dissipation holes 3. Since there are many heat dissipation holes 3, it is sufficient to conduct random inspections on the heat dissipation holes 3. For example, five heat dissipation holes 3 are inspected. As long as there are no cleaning pieces 6 in more than two heat dissipation holes 3, the cleaning pieces 6 need to be softened or even replaced. First, move the slide 23 to a position close to the side wall of the cabinet 1. If the detection rod 24 is moved in a direction away from the cabinet 1, it proves that there is a cleaning piece 6 in the heat dissipation holes 3. If the detection rod 24 is not pushed, it proves that there is no cleaning piece 6 in the heat dissipation holes 3.

[0028] The identification component includes an infrared transmitter 28, an infrared receiver 29, an identification rod 30 and a recording part for recording the number of heat dissipation holes 3 that have not been cleaned. The infrared transmitter 28 and the infrared receiver 29 are both fixed on the slide 23. The identification rod 30 is provided with an identification hole 31. The signal of the infrared transmitter 28 passes through the identification hole 31 and is received by the infrared receiver 29. The infrared receiver 29 controls the operation of the operating component. The infrared transmitter 28 and the infrared receiver 29 are respectively located on both sides of the identification hole 31. The recording part includes a second proximity switch 32, a recording electric push rod 33 and a recording rod 34. The recording electric push rod 33 is arranged on the outer wall of the auxiliary box 7. The second proximity switch 32 is arranged on the outer wall of the auxiliary box 7. The recording electric push rod 33 controls the movement of the recording rod 34. The infrared receiver 29 is electrically connected to the second proximity switch 32.

[0029] If the detection rod 24 is not pushed, it proves that there is no cleaning piece 6 in the heat dissipation hole 3, and the infrared receiver 29 can receive the signal of the infrared transmitter 28. Of course, in this embodiment, the size of the cleaning piece 6 in the heat dissipation hole 3 is also set. If the set size is not reached, it will also be marked as there is no cleaning piece 6 in this heat dissipation hole 3. If the size of the cleaning piece 6 in the heat dissipation hole 3 is close to the set value, that is, it is within the allowable error range, the identification rod 30 will also be pushed, but the size of the identification hole 31 is allowed to move within the allowable error range, that is, it will also be recognized that there is a cleaning piece 6 in this heat dissipation hole 3; and when the infrared receiver 29 receives the signal of the infrared transmitter 28, the recording electric push rod 33 controls the movement of the recording rod 34. The size between the end of the recording rod 34 and the second proximity switch 32 is equal to the distance that the recording electric push rod 33 controls the movement of the recording rod 34 three times. If the top of the recording rod 34 abuts against the second proximity switch 32, it proves that the cleaning piece 6 needs to be processed.

[0030] The operating component includes two extrusion plates 35 slidably arranged in the cleaning box 4 and two extrusion electric push rods 36 for controlling the reciprocating movement of the extrusion plates 35. The two extrusion plates 35 are respectively arranged on both sides of the cleaning box 4 in the vertical direction. Under the interaction of the two extrusion plates 35, the cleaning piece 6 can be rubbed; the operating component also includes a storage tank 37, a storage tube 38, an outlet tube 39 and a solenoid valve 40. The storage tank 37 is arranged at the top of the cleaning box 4, and the extrusion plate 35 located above is provided with an outlet hole. The outlet tube 39 is arranged in the outlet hole and the end of the outlet tube 39 is flush with the surface of the extrusion plate 35. One end of the storage tube 38 is connected to the storage tank 37, and the other end is connected to the outlet tube 39. The solenoid valve 40 is arranged on the storage tube 38. The storage tank 37 is filled with a softener for softening the cleaning piece 6. In this embodiment, the softener is selected from wind oil essence, which is an organic solution that can soften the sponge head.

[0031] In this embodiment, the cleaning piece 6 can be kneaded under the action of the extrusion plate 35, which is conducive to the softening of the cleaning piece 6. Of course, during the detection process, the cleaning piece 6 can be temporarily moved away from the heat dissipation hole 3, and then kneaded by two extrusion plates 35, and the cleaning piece 6 can be transported to the position of the heat dissipation hole 3. If the detection is still unqualified, the cleaning piece 6 is pulled to a position away from the heat dissipation hole 3, and the extrusion plate 35 is pulled to a position abutting against the cleaning piece 6. Since the storage tank 37 is located above the cleaning box 4, after the solenoid valve 40 is opened, the softener enters the outlet pipe 39 on the extrusion plate 35. After the softener is fused with the cleaning piece 6, combined with the combination effect of the extrusion plate 35, the softening effect of the cleaning piece 6 is achieved, ensuring that the cleaning piece 6 can be squeezed into the heat dissipation hole 3.

[0032] The implementation principle of a split low-voltage reactive power compensation cabinet in the embodiment of the present application is as follows: if the detection rod 24 is not pushed, it is proved that there is no cleaning piece 6 in the heat dissipation hole 3, and the infrared receiver 29 can receive the signal of the infrared transmitter 28. Of course, in this embodiment, the size of the cleaning piece 6 in the heat dissipation hole 3 is also set. If the set size is not reached, it will also be marked that there is no cleaning piece 6 in the heat dissipation hole 3. If the size of the cleaning piece 6 in the heat dissipation hole 3 is close to the set value, that is, it is within the allowable error range, the identification rod 30 will also be pushed, but the size of the identification hole 31 is allowed to move within the allowable error range, that is, it will also be recognized that there is a cleaning piece 6 in the heat dissipation hole 3; and when the infrared receiver 29 receives the signal of the infrared transmitter 28, the recording electric push rod 33 controls the movement of the recording rod 34, and the size between the end of the recording rod 34 and the second proximity switch 32 is equal to the distance that the recording electric push rod 33 controls the movement of the recording rod 34 three times. If the top of the recording rod 34 abuts against the second proximity switch 32, it is proved that the cleaning piece 6 needs to be processed; First, the cleaning piece 6 is kneaded under the action of the squeezing plate 35, which is conducive to the softening of the cleaning piece 6. Of course, during the detection process, the cleaning piece 6 can be temporarily moved away from the heat dissipation hole 3, and then the cleaning piece 6 can be kneaded by the two squeezing plates 35, and the cleaning piece 6 can be transported to the position of the heat dissipation hole 3. If the detection is still unqualified, the cleaning piece 6 is pulled to a position away from the heat dissipation hole 3, and the squeezing plate 35 is pulled to a position abutting against the cleaning piece 6. Since the storage tank 37 is located above the cleaning box 4, after the solenoid valve 40 is opened, the softener enters the outlet pipe 39 on the squeezing plate 35. After the softener is fused with the cleaning piece 6, combined with the combination effect of the squeezing plate 35, the softening effect of the cleaning piece 6 is achieved, ensuring that the cleaning piece 6 can be squeezed into the heat dissipation hole 3; When cleaning the heat dissipation holes 3, alcohol is sprayed first, and then enters the heat dissipation holes 3, and is partially adsorbed by the cleaning member 6. The isolation member 8 is controlled to move to a position covering the heat dissipation holes 3, and the isolation member 8 fits the outer wall of the cabinet 1, thereby further reducing the volatilization of alcohol. The cleaning member 6 is squeezed toward the heat dissipation holes 3 by the control member and deformed toward the heat dissipation holes 3. Under the mutual cooperation of the cleaning member 6 and alcohol, the cleaning effect of the heat dissipation holes 3 is achieved.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
