Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to electrical field especially relates to a kind of electrical equipment leakage monitoring devices. BACKGROUND
[0002] When using electrical equipment, the electrical equipment needs to be monitored for leakage to achieve the purpose of safe use, and the electrical equipment needs to be powered off in time during leakage monitoring to prevent electric shock to achieve the purpose of effective monitoring.
[0003] Since the device state needs to be indicated in time during leakage monitoring, the current leakage monitoring device is not convenient to indicate the current state of the device during leakage monitoring, and the electrical equipment cannot be quickly turned off when it leaks, which leads to the electrical equipment still being in a leakage state, and thus leads to poor monitoring effect. UTILITY MODEL CONTENT
[0004] To overcome the above shortcomings, the utility model provides a kind of electrical equipment leakage monitoring device.It can be powered off in time when electrical equipment leaks to improve safety and can prompt electrical equipment leakage to enhance monitoring effect.
[0005] The technical implementation scheme of the utility model is: a kind of electrical equipment leakage monitoring device, including fixed box, the inner wall of the fixed box is fixedly connected with conducting plate, the conducting plate is connected with indicating lamp by wire, the indicating lamp is fixedly connected on the fixed box, the conducting plate is fixedly connected with two electric wires, two electric wires all pass through the fixed box, the one end of two electric wires is fixedly connected with contact, two electric wires are all fixedly connected with fixed frame, two contacts pass through two fixed frames respectively, two fixed frames are all equipped with sticky block, the conducting plate is equipped with pressing assembly, the pressing assembly is connected with the fixed box, the pressing assembly is equipped with prompt assembly, the prompt assembly is connected with the fixed box, the pressing assembly is used to press switch, and the prompt assembly is used to prompt leakage.
[0006] Optionally, the fixed frame is a conical structure.
[0007] Optionally, the pressing assembly includes electromagnet, two electromagnets are fixedly connected on the two sides of the conducting plate, two electromagnets are symmetrically arranged, the inner wall of the fixed box is slidably connected with push rod, the push rod is fixedly connected with two iron blocks, two iron blocks are symmetrically arranged, and the push rod is connected with the fixed box through compression spring.
[0008] Optionally, the prompting component includes a first rack fixedly connected to one side of the push rod, a fixed seat fixedly connected inside the fixed box, a gear rotatably connected to the fixed seat, a second rack slidably connected to the inner wall of the fixed box, the first rack and the second rack respectively meshing with the gear, an indicator frame slidably connected to the fixed box, the top of the second rack contacting the bottom of the indicator frame, a moving block slidably connected to the fixed box, and two tension springs connecting the moving block and the fixed box.
[0009] Compared with the prior art, the present invention has the following advantages: 1. When the electrical equipment leaks current, the current is transmitted through the contacts, wires and conductive plates, and the indicator light is lit, thereby monitoring the leakage of the electrical equipment. When the electrical equipment leaks current, the electromagnet is energized to generate magnetic force, which causes the push rod to move downward through the iron block to press the switch, thereby quickly cutting off the power to the electrical equipment, thus preventing accidents caused by leakage, and thus enhancing the monitoring effect.
[0010] 2. As the push rod moves downward, it drives the first rack downward. The downward movement of the first rack, through the gear, causes the second rack to move upward, pressing the indicator frame upward. The upward movement of the indicator frame presses the moving block to one side, stretching the tension spring. The indicator frame continues to move and no longer presses the moving block. The tension spring resets, causing the moving block to reset. The reset of the moving block will lock the indicator frame, thus extending the indicator frame. The reset of the push rod causes the first rack to reset, which in turn drives the second rack to reset through the gear. The second rack disengages from the indicator frame, thus indicating electrical equipment leakage, thereby further enhancing the monitoring effect. Attached Figure Description

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example 1: An electrical equipment leakage current monitoring device, such as Figures 1-6 As shown, the device includes a fixed box 5, a conductive plate 6 welded to the inner wall of the fixed box 5, an indicator light 7 connected to the conductive plate 6 via wires, the indicator light 7 being used to indicate leakage current, the indicator light 7 being fixedly connected to the fixed box 5, two wires 4 welded to the conductive plate 6, both wires passing through the fixed box 5, a contact 3 welded to one end of each of the two wires 4, a fixing frame 1 welded to each of the two wires 4, the two contacts 3 passing through the two fixing frames 1 respectively, an adhesive block 2 provided on each of the two fixing frames 1, a pressing assembly provided on the conductive plate 6, the pressing assembly being connected to the fixed box 5, a prompting component provided on the pressing assembly, the prompting component being connected to the fixed box 5, the pressing assembly being used to press a switch, and the prompting component being used to indicate leakage current.
[0020] The fixing frame 1 has a conical structure and is used to protect the contact 3.
[0021] The pressing assembly includes an electromagnet 8, two electromagnets 8 are respectively fixedly connected to both sides of the conductive plate 6, and the two electromagnets 8 are arranged symmetrically. A push rod 9 is slidably connected to the inner wall of the fixed box 5. The push rod 9 is used to press the switch. Two iron blocks 10 are fixedly connected to the push rod 9, and the two iron blocks 10 are arranged symmetrically. A compression spring 11 is connected between the push rod 9 and the fixed box 5.
[0022] The indicator component includes a first rack 12, which is fixedly connected to one side of the push rod 9. A fixed base 13 is fixedly connected inside the fixed box 5. A gear 14 is rotatably connected to the fixed base 13. A second rack 15 is slidably connected to the inner wall of the fixed box 5. The first rack 12 and the second rack 15 respectively mesh with the gear 14. An indicator frame 16 is slidably connected to the fixed box 5. The indicator frame 16 is used to indicate the leakage status of electrical equipment. The top of the second rack 15 contacts the bottom of the indicator frame 16. A moving block 17 is slidably connected to the fixed box 5. Two tension springs 18 are connected between the moving block 17 and the fixed box 5.
[0023] When leakage current monitoring of electrical equipment is required, the operator first uses adhesive block 2 to fix the mounting bracket 1 to the electrical equipment, ensuring the two contacts 3 are in contact with the equipment. Simultaneously, the mounting box 5 is fixed above the switch of the electrical equipment. The push rod 9 is aligned with the switch. When the electrical equipment leaks current, the current is transmitted through the contacts 3, wires 4, and conductive plate 6, illuminating the indicator light 7, thus monitoring the leakage current. Simultaneously, the conductive plate 6 conducts electricity, energizing the electromagnet 8 and generating a magnetic force. The magnetic force of the electromagnet 8 attracts the iron block 10, causing it to move downwards. The movement of the iron block 10 moves the push rod 9, compressing the compression spring 11. The push rod 9 presses the switch, turning off the electrical equipment. With the switch closed, the electrical equipment is no longer energized, the electromagnet 8 is de-energized, and its magnetic force disappears. The compression spring 11 resets, causing the push rod 9 and iron block 10 to reset. This process is repeated. When the electrical equipment leaks current, the electromagnet 8 is energized, generating a magnetic force that, through the iron block 10, causes the push rod 9 to move downwards and press the switch. The switch quickly cuts off power to the electrical equipment, preventing accidents caused by leakage and enhancing the monitoring effect. As the push rod 9 moves downward, it drives the first rack 12 downward. The movement of the first rack 12, through the gear 14, causes the second rack 15 to move upward. The upward movement of the second rack 15 compresses the indicator frame 16, causing it to move upward. The upward movement of the indicator frame 16 compresses the moving block 17 to one side, stretching the tension spring 18. The indicator frame 16 continues to move and no longer compresses the moving block 17. The tension spring 18 resets, causing the moving block 17 to reset. The reset of the moving block 17 will lock the indicator frame 16, thus extending the indicator frame 16. The reset of the push rod 9 causes the first rack 12 to reset. The reset of the first rack 12, through the gear 14, causes the second rack 15 to reset. The second rack 15 disengages from the indicator frame 16, thus indicating leakage in the electrical equipment and further enhancing the monitoring effect. After the electrical equipment is repaired, the indicator frame 16 can be pushed back.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
