Description

Technical Field

[0001] The utility model relates to the technical field of distribution switch control equipment, in particular to an alarm device for a distribution switch control equipment. Background Art

[0002] Among electrical equipment, the most frequently used one is the distribution switch control equipment. The design of the distribution switch control equipment can make it more convenient to place electrical equipment, and at the same time, it has better protection for electrical equipment;

[0003] Chinese Patent Grant Publication No. CN220527433U discloses a distribution switch control equipment, including a cabinet body. Ventilation openings are provided on the side wall of the cabinet body. A closing mechanism is installed on the inner wall of the cabinet body. The closing mechanism includes a bracket, a spring, a closing plate and a hot-melt foam block. A guide rail is provided on the bracket, a guide groove is provided on the closing plate, and a closing block for closing the ventilation opening is provided on the closing plate. The spring is arranged between the bracket and the closing plate to push the closing plate to move towards the cabinet body. The hot-melt foam block is arranged between the closing plate and the cabinet body. When a fire breaks out inside the cabinet, the high temperature will melt the hot-melt foam block, and then the spring will push the closing plate to move towards the ventilation opening, cutting off the gas exchange between the inside and the outside of the cabinet body, so that there is no oxygen inside the cabinet body, thus playing a role in extinguishing the fire and reducing the damage of the fire to the equipment inside the cabinet. When a fire breaks out outside the cabinet, through a process similar to that of an internal fire, the closing block can block the flame outside the cabinet, reducing the damage of the fire to the equipment inside the cabinet.

[0004] By referring to the above patent documents, it can be seen that the prior art still has the following deficiencies. Since the distribution switch control equipment belongs to relatively important electrical equipment, for safety reasons, generally, except for staff, outsiders are not allowed to operate the inside of the distribution switch control equipment. However, due to the lack of monitoring and alarm measures for illegal operations in the distribution switch control equipment, the situation of outsiders' illegal operations often occurs. Outsiders' illegal operations not only easily affect the normal operation of the distribution switch control equipment, but also, if the operation is improper, there are certain potential safety hazards. Content of the Utility Model

[0005] The utility model provides an alarm device for a distribution switch control equipment, which is beneficial to monitoring and alarming the distribution switch control equipment and warning outsiders not to operate the distribution switch control equipment illegally.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An alarm device for a distribution switch control equipment, including a distribution cabinet, a cabinet door and a switch controller. The cabinet door covers the front end of the distribution cabinet, and the switch controller is installed inside the distribution cabinet;

[0008] There is an installation groove at the top inside the power distribution cabinet. A pressing plate is arranged in the installation groove. An arc-shaped convex block is fixed at the lower end of the pressing plate. The arc-shaped convex block extends downward out of the installation groove. The upper end of the cabinet door abuts against the lower end of the arc-shaped convex block. At least two return springs are connected between the upper end of the pressing plate and the top end inside the installation groove. A proximity switch is connected to the bottom end inside the installation groove. A proximity plate connected to the lower end of the pressing plate is arranged above the proximity switch. A first alarm is arranged outside the power distribution cabinet. A buzzer is installed in the installation groove;

[0009] Limit components are arranged at both the left and right ends of the pressing plate.

[0010] Further, a first electromagnet is fixed at the top end inside the installation groove. A magnetic attraction block connected to the upper end of the pressing plate is arranged below the first electromagnet.

[0011] Further, two guide rods are fixed inside the installation groove. The pressing plate is slidably sleeved on the guide rods.

[0012] Further, each of the limit components includes a magnetic attraction plate, a limit plate, a ball, a guide shaft, a return spring and a second electromagnet. Grooves are opened at both the left and right ends of the inner wall of the installation groove. The magnetic attraction plate is arranged in the groove. The limit plate is fixed on the inner side of the magnetic attraction plate and extends into the installation groove. The ball is rotatably connected to the inner end of the limit plate and abuts against the side surface of the pressing plate.

[0016] 1. By abutting the upper end of the cabinet door against the lower end of the arc-shaped convex block, at this time, the proximity switch and the proximity plate are at a safe distance. If an outsider illegally opens the cabinet door to operate the inside of the power distribution cabinet, the elastic force of the return spring and the gravity of the arc-shaped convex block will drive the pressing plate and the proximity plate to automatically move downward, so that the proximity switch will sense the proximity plate and start. The buzzer will emit a beeping alarm at the site of the power distribution switch control device, which is beneficial to reminding the outsider not to continue operating the device. And the first alarm emits an alarm sound to remind the staff. The staff can arrive at the scene in time to stop the outsider's illegal operation, thus avoiding the situation that the normal operation of the power distribution switch control device is affected due to illegal operation, so as to avoid potential safety hazards caused by the outsider's operation;

[0017] 2. By blocking the upward movement position of the pressing plate with the limit plate, it can prevent malicious upward pushing of the arc-shaped convex block, the pressing plate, and the proximity plate by outsiders, so that outsiders cannot stop the buzzer and the first alarm from working, which is beneficial to keeping the alarm effect in a normal state.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with the embodiments and the drawings. The content mentioned in the embodiments does not limit the present utility model.

[0026] As Figures 1-5As shown in the figure, in this embodiment, it includes a power distribution cabinet 1, a cabinet door 2 and a switch controller 5. The cabinet door 2 covers the front end of the power distribution cabinet 1. The switch controller 5 is installed inside the power distribution cabinet 1. There is an installation groove 6 at the top end inside the power distribution cabinet 1. A pressure plate 7 is provided in the installation groove 6. An arc-shaped convex block 11 is fixed at the lower end of the pressure plate 7. The arc-shaped convex block 11 extends downward out of the installation groove 6. The upper end of the cabinet door 2 abuts against the lower end of the arc-shaped convex block 11. At least two return springs 8 are connected between the upper end of the pressure plate 7 and the top end inside the installation groove 6. A proximity switch 14 is connected to the bottom end inside the installation groove 6. Above the proximity switch 14, there is a proximity plate 23 connected to the lower end of the pressure plate 7. A first alarm 3 is provided outside the power distribution cabinet 1. A buzzer 10 is installed in the installation groove 6. Two guide rods 9 are fixed in the installation groove 6. The pressure plate 7 is slidably sleeved on the guide rods 9.

[0027] By abutting the upper end of the cabinet door 2 against the lower end of the arc-shaped convex block 11, at this time, the proximity switch 14 and the proximity plate 23 are at a safe distance, and at this time, the pressure plate 7 compresses the return spring 8. Therefore, on the premise that the proximity switch 14, the buzzer 10 and the first alarm 3 are set in series, and the first alarm 3 is installed in the monitoring room of the staff. If an outsider illegally opens the cabinet door 2 to operate the inside of the power distribution cabinet 1, the elastic force of the return spring 8 and the gravity of the arc-shaped convex block 11 will drive the pressure plate 7 and the proximity plate 23 to move downward automatically, and the pressure plate 7 slides along the guide rod 9, which is beneficial to ensuring the stability of the pressure plate 7 during movement. Therefore, the proximity plate 23 will approach the induction end of the proximity switch 14, so that the proximity switch 14 will sense the proximity plate 23 and start. After the switch is started, the buzzer 10 and the first alarm 3 will be powered on to work. The buzzer 10 will emit a beeping alarm at the site of the power distribution switch control device, which is beneficial to reminding the outsider not to continue operating the device, and the first alarm 3 emitting an alarm sound can remind the staff. At this time, the staff will know immediately that an outsider is operating the device illegally. Therefore, the staff can arrive at the scene in time to stop the outsider's illegal operation, thus avoiding the situation that the illegal operation affects the normal operation of the power distribution switch control device and preventing safety hazards caused by the outsider's operation.

[0028] As Figures 3-5As shown, in this embodiment, limiting components are provided at both the left and right ends of the pressing plate 7. Each of the limiting components includes a magnetic attraction plate 16, a limiting plate 17, a ball 21, a guiding shaft 19, a return spring 20, and a second electromagnet 18. Grooves 15 are formed at both the left and right ends of the inner wall of the installation groove 6. The magnetic attraction plate 16 is disposed in the groove 15. The limiting plate 17 is fixed to the inner side of the magnetic attraction plate 16 and extends into the installation groove 6. The ball 21 is rotatably connected to the inner end of the limiting plate 17 and abuts against the side surface of the pressing plate 7. The guiding shaft 19 is fixed in the installation groove 6. The magnetic attraction plate 16 is slidably sleeved on the guiding shaft 19. The return spring 20 is connected between the outer side of the magnetic attraction plate 16 and the inner side wall of the groove 15. The second electromagnet 18 is connected to the inner side wall of the groove 15, and the magnetic attraction plate 16 and the second electromagnet 18 are corresponding to each other left and right.

[0029] Before the pressing plate 7 moves downward, since the ball 21 abuts against the side surface of the pressing plate 7, at this time the magnetic attraction plate 16 compresses the return spring 20. Therefore, when the pressing plate 7 moves downward, the pressing plate 7 will move downward along the ball 21. Combining with the rotation of the ball 21, the smoothness of the downward movement of the pressing plate 7 can be ensured. Then, the resilience of the return spring 20 will drive the magnetic attraction plate 16 to slide along the guiding shaft 19. At the same time, the magnetic attraction plate 16 will drive the limiting plate 17 to move above the pressing plate 7, playing a role in limiting the pressing plate 7. Then, the limiting plate 17 blocks the upward movement position of the pressing plate 7, avoiding the situation that an outsider maliciously pushes the arc-shaped convex block 11, the pressing plate 7, and the approaching plate 23 upward. As long as the approaching plate 23 does not reset upward to the initial position, the proximity switch 14 will not stop working. Therefore, an outsider cannot stop the operation of the buzzer 10 and the first alarm 3, which is beneficial to keeping the alarm effect in a normal state.

[0030] As Figure 3 , 5 As shown, in this embodiment, the magnetic attraction plate 16 is disposed in the groove 15. The limiting plate 17 is fixed to the inner side of the magnetic attraction plate 16 and extends into the installation groove 6. The ball 21 is rotatably connected to the inner end of the limiting plate 17 and abuts against the side surface of the pressing plate 7. The guiding shaft 19 is fixed in the installation groove 6. The magnetic attraction plate 16 is slidably sleeved on the guiding shaft 19. The return spring 20 is connected between the outer side of the magnetic attraction plate 16 and the inner side wall of the groove 15. The second electromagnet 18 is connected to the inner side wall of the groove 15, and the magnetic attraction plate 16 and the second electromagnet 18 are corresponding to each other left and right.

[0031] When it is necessary to move the arc-shaped bump 11, the pressing plate 7 and the proximity plate 23 upward for reset, the second electromagnet 18 works to adsorb the magnetic plate 16. The magnetic plate 16 slides along the guide shaft 19. At the same time, the magnetic plate 16 compresses the return spring 20 until the second electromagnet 18 adsorbs the magnetic plate 16. At this time, the magnetic plate 16 drives the limiting plate 17 to move away from above the pressing plate 7. Then when the cabinet door 2 is closed, the cabinet door 2 will push the arc-shaped bump 11 and the pressing plate 7 upward along the arc surface of the arc-shaped bump 11. The pressing plate 7 will compress the return spring 8 until the cabinet door 2 is closed. At this time, the limiting plate 17 and the pressing plate 7 are corresponding left and right. Then the second electromagnet 18 is powered off and no longer adsorbs the magnetic plate 16. The resilience of the combined return spring 20 will drive the magnetic plate 16, the limiting plate 17 and the ball 21 to move towards the position close to the side of the pressing plate 7 until the ball 21 abuts against the side of the pressing plate 7, so that the first alarm 3 and the buzzer 10 are in a normal early warning state.

[0032] As Figure 3 , 5 shown, in this embodiment, a first electromagnet 12 is fixed at the top end inside the installation groove 6, and a magnetic attraction block 13 connected to the upper end of the pressing plate 7 is arranged below the first electromagnet 12.

[0033] When the staff needs to normally open the cabinet door 2 to operate inside the power distribution cabinet 1, the first electromagnet 12 works to adsorb the magnetic attraction block 13 upward. The magnetic attraction block 13 will drive the pressing plate 7 and the proximity plate 23 to move upward and away from the proximity switch 14. At the same time, the pressing plate 7 will drive the arc-shaped bump 11 to move upward, so that the arc-shaped bump 11 no longer contacts the cabinet door 2. When the staff normally opens the cabinet door 2, the arc-shaped bump 11 and the proximity plate 23 will not move downward, so the first alarm 3 and the buzzer 10 will not sound an alarm, which is beneficial for the staff to normally operate the power distribution switch control device.

[0034] As Figure 4 shown, in this embodiment, a leakage switch 22 is installed inside the power distribution cabinet 1. The switch controller 5 is connected to the leakage switch 22 through an electric wire. A second alarm 4 is installed outside the power distribution cabinet 1, and the leakage switch 22 is connected in series with the second alarm 4.

[0035] The leakage situation of the switch controller 5 is monitored through the leakage switch 22. Once the switch controller 5 leaks electricity, the leakage switch 22 will control the second alarm 4 to sound an alarm. On the premise that the second alarm 4 is installed in the monitoring room, the staff can timely know in the monitoring room that there is a risk of leakage of the switch controller 5, which is beneficial for timely maintenance of the device.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementation solutions of the present utility model. In addition, there are other implementation manners. Any obvious substitution without departing from the concept of the technical solution is within the protection scope of the present utility model.
