Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric control cabinet devices, in particular to an electric control cabinet with leakage protection. Background Art
[0002] In the existing electrical safety field, in order to prevent personal injury and property loss caused by equipment leakage, the traditional solution is mainly to use leakage protectors. These leakage protectors are usually installed in the power system and automatically cut off the power supply when current leakage is detected to achieve the protection effect. However, these traditional methods have certain limitations. For example, the response time is relatively long, it is easily interfered by environmental factors, and misoperation may occur when the load changes greatly, which leads to poor user experience and may affect the normal operation of the equipment.
[0003] A Chinese patent with the publication number of CN 220914787 U discloses a leakage protection electric control cabinet, which includes a box body, a support rod, a cover plate, a leakage detection device, a drive box and a controller. The support rod is rotatably connected between the top and bottom of the inner cavity of the box body on the left side. The cover plate is located on the front side of the box body. The leakage detection device is located in the inner cavity of the box body. The drive box is fixedly connected to the top left side of the box body. The controller is fixedly connected to the middle of the bottom of the inner cavity of the box body. A partition is fixedly connected to the outer side wall of the support rod. This leakage protection electric control cabinet has a reasonable structural design, realizes the function of automatically opening and closing the electric control cabinet, eliminates the need for operators to directly contact the outer side wall of the electric control cabinet, is beneficial to the safety during the actual use of the electric control cabinet, facilitates maintenance personnel to quickly confirm the leakage position, reduces the work burden of operators, and improves the efficiency during the actual detection and maintenance of the electric control cabinet.
[0004] Based on the above search and in combination with the existing technology, it is found that:
[0005] After the existing device triggers the controller, the controller controls the variable-frequency motor to operate. The variable-frequency motor drives the support rod to rotate. The support rod drives the partition to rotate. At the same time, the roller rotates at the bottom of the partition and supports the partition. Finally, it leaves the inside of the box body to complete the automatic opening and closing of the electric control cabinet. However, after a leakage occurs, the charged cabinet body will affect the operation of the motor, resulting in the motor being unable to drive the support rod to rotate, thus unable to realize the automatic opening and closing of the electric control cabinet, which is not conducive to actual use.

[0022] As Figures 1-3As shown in the figure, a leakage protection electric control cabinet includes a cabinet body 1. A chute 2 is provided on the cabinet body 1. A cabinet door 3 is slidably connected to the chute 2. A connecting block 4 is fixedly installed on the cabinet door 3. A fixed block 5 is fixedly installed on the cabinet body 1. A spring 6 is connected to the fixed block 5. The other end of the spring 6 is connected to the connecting block 4. A first mounting bracket 7 is fixedly installed on one side of the cabinet body 1. A first pulley 8 is rotatably connected to the first mounting bracket 7. A second mounting bracket 9 is fixedly installed above the cabinet body 1. A second pulley 10 is rotatably connected to the second mounting bracket 9. A third mounting bracket 11 is fixedly installed on the other side of the cabinet body 1. A third pulley 12 is rotatably connected to the third mounting bracket 11. The cabinet door 3 slides on the chute 2. Under normal circumstances, the connecting block 4 is pulled by the action of the spring 6 to keep the cabinet door 3 in a closed state.
[0023] Furthermore, a cable 13 is fixedly connected to the connecting block 4. The cable 13 is slidably connected to the first pulley 8, the second pulley 10 and the third pulley 12. The other end of the cable 13 is fixedly connected to a handle 14. The handle 14 is made of insulating material. A pair of hooks 15 are fixedly installed on one side of the cabinet body 1. The pair of hooks 15 are made of insulating material. The cable 13 on the connecting block 4 can pull the cabinet door 3 to move. When it is necessary to open the cabinet door 3, the cable 13 is pulled by the handle 14. Since the handle 14 is made of insulating material, it will not cause harm to the staff due to electric leakage.
[0024] Furthermore, a plurality of heat dissipation openings 16 are provided on the cabinet body 1. A buzzer alarm 17 is fixedly installed on the cabinet body 1. The heat dissipation openings 16 can be used for heat dissipation.
[0025] Furthermore, a plurality of bearing plates 18 are fixedly installed inside the cabinet body 1. The plurality of bearing plates 18 are arranged staggeredly. A plurality of holes are provided on each of the plurality of bearing plates 18. An induction plate 19 is fixedly installed inside the cabinet body 1. A pair of transmission wires 20 are connected to each of the plurality of bearing plates 18. The other ends of the plurality of pairs of transmission wires 20 are all connected to the induction plate 19. The induction plate 19 is electrically connected to the buzzer alarm 17. When an electrical appliance on the bearing plate 18 has a leakage, the current will be transmitted to the induction plate 19 through the transmission wire 20. The induction plate 19 sends a signal to the buzzer alarm 17, and the buzzer alarm 17 issues an alarm to remind the staff to carry out maintenance.
[0026] Furthermore, a plurality of support feet 21 are fixedly installed at the bottom of the cabinet body 1 to play a supporting role.
[0027] The specific working method is as follows: The device places electrical appliances on multiple bearing plates 18 inside the cabinet body 1. The multiple bearing plates 18 are staggeredly arranged and are provided with multiple holes, effectively improving the heat dissipation efficiency. The heat generated by the electrical appliances can be dissipated from multiple heat dissipation openings 16 opened above the cabinet body 1. If an electrical leakage occurs in the electrical appliance, the bearing plate 18 is made of a conductive material, and the current passes through the bearing plate 18 and is transmitted to the induction plate 19 through the transmission wire 20. The induction plate 19 transmits the signal to the buzzer alarm 17 above the cabinet body 1, and the buzzer alarm 17 emits an alarm to remind the staff to carry out maintenance. When the staff conducts daily inspections, in order to prevent electric shock due to no alarm being issued when there is electric leakage, touching the cabinet door 3 directly will cause a risk of electric shock. By pulling the handle 14, the cable 13 connected to the handle 14 is pulled. The cable 13 passes through the first pulley 8, the second pulley 10, and the third pulley 12 and is connected to the connecting block 4, and the cabinet door 3 connected to the connecting block 4 can be pulled to open it. Then, the handle 14 is placed on the hook 15 and hooked, so that the cabinet door 3 can be in an open state. Since both the handle 14 and the hook 15 are made of insulating materials, no electric shock danger will occur. After the inspection is completed, the handle 14 is removed from the hook 15, and the connecting block 4 drives the cabinet door 3 to close under the action of the spring 6. The opening and closing of the cabinet door 3 do not require the participation of the electrical appliance. In the case of electric leakage, the staff can safely carry out the inspection, and the situation where the cabinet body 1 is electrified and affects the operation of the electrical appliance, resulting in the inability to open the cabinet door 3, will not occur.
