Description

Technical Field

[0001] This application relates to the technical field of power distribution switchgear, and in particular to a power distribution switchgear for coal mine electromechanical transportation transmission electrical engineering. Background Technology

[0002] The power distribution switchgear in coal mine electromechanical transportation transmission electrical engineering is a key component of the power supply system for underground and surface electromechanical equipment in coal mines. Its main function is to control and protect electrical equipment, ensuring the rational distribution and safe use of electrical energy. Due to its use in coal mines, it is usually equipped with a corresponding protective enclosure, mainly to protect against damage to internal electrical components caused by dust, water splashes, and mechanical collisions.

[0003] A search revealed Chinese patent application CN202222703049.6, which discloses a power distribution switch device for coal mine electromechanical transportation transmission electrical engineering. The device includes a distribution box, a distribution board, a switch, and a movable door. The distribution board is connected inside the distribution box, and the switch is connected to the front end of the distribution board. The movable door is also connected to the front end of the distribution box, which serves as the supporting foundation. In this power distribution switch device, rotating the handle drives a threaded rod to rotate, which in turn drives an L-shaped fixing hole into the L-shaped fixing hole for clamping and fixing. This allows for the easy splicing and centralized management of multiple power distribution switch devices. Pushing the concave locking block engages a J-shaped plate at one end of the locking plate, and releasing the concave locking block engages the other end of the locking plate, allowing users to quickly assemble or disassemble the switch. Lifting the sealing strip engages a T-shaped locking block in the slot, sealing the inside of the distribution box and preventing moisture from entering.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: When disassembling and assembling the switch, it is easy to bump into other electrical components inside the distribution box, which may damage these components or cause malfunctions. Furthermore, inside the distribution box, due to the close arrangement of various electrical components, the space is very limited. When maintenance personnel operate inside, their hand movement range is small, and the use of tools is also subject to many restrictions, resulting in limited operating space and affecting the efficiency of subsequent maintenance.

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses a power distribution switch device for electromechanical transportation transmission electrical engineering in coal mines. For example... Figure 1 - Figure 4 As shown, it includes an outer casing 1. A convex groove 2 is provided on the upper side of the inner wall of the outer casing 1. A sliding block 3 is slidably fitted on the inner wall of the convex groove 2. An mounting plate 21 is fixedly connected to the lower side of the sliding block 3. Multiple power distribution switch bodies 4 are provided on one side of the mounting plate 21. A card seat 5 is fixedly connected to one side of the mounting plate 21.

[0024] Please see Figure 1 The outer casing 1 has a rotatable sealing door 12 on one side, and an operating handle 13 is fixedly connected to one side of the sealing door 12. The sealing door 12 can be used to seal the front of the outer casing 1 for moisture protection, and the operating handle 13 can be used to apply force when operating the sealing door 12.

[0025] Please see Figure 2Both sides of the outer box 1 are fixedly connected to fixing plates 16. Each fixing plate 16 has a mounting hole 17 on one side. By passing bolts, collision screws and other connecting parts through the mounting hole 17, the fixing plate 16 can be fixed, thereby fixing the outer box 1.

[0026] A connecting plate 6 is fixedly connected to one side of the inner wall of the outer casing 1. A hidden groove 7 is opened on the upper side of the connecting plate 6. Multiple springs 20 are fixedly connected to the lower side of the inner wall of the hidden groove 7. A locking tongue 8 that slides with the hidden groove 7 is fixedly connected to the upper end of the multiple springs 20. The locking tongue 8 is inserted into the card seat 5. An operating port 9 is opened on one side of the hidden groove 7. A lower pressure plate 10 that is fixedly connected to the locking tongue 8 slides with the inner wall of the operating port 9. An lighting component 11 that cooperates with the sliding block 3 is provided inside the outer casing 1.

[0027] Please see Figure 2 The lighting assembly 11 includes a push switch 111 fixedly connected to one side of the inner wall of the convex slide groove 2, and lighting lamps 112 fixedly connected to both sides of the inner wall of the outer casing 1. The push switch 111 and the lighting lamps 112 are electrically connected. When pulled to the outermost position, the sliding block 3 will press the push switch 111. After the push switch 111 is pressed, the lighting lamps 112 are turned on to automatically illuminate both sides of the mounting plate 21. When the sliding block 3 is separated from the push switch 111, the lighting lamps 112 are automatically turned off. This provides sufficient light for maintenance personnel to clearly see the various electrical components inside the device, improving the operability of maintenance.

[0028] Please see Figure 2 and Figure 3 A reinforcing plate 14 is fixedly connected to the upper side of the lower pressure plate 10. The reinforcing plate 14 cooperates with the card seat 5. When the mounting plate 21 moves to the outside, the spring 20 presses the locking tongue 8 upward, and at the same time drives the lower pressure plate 10 and the reinforcing plate 14 to move upward, so that after the reinforcing plate 14 is inserted into the card seat 5, the pulled-out mounting plate 21 can be temporarily fixed.

[0029] Please see Figure 2 A top pressure block 15 is fixedly connected to one side of the sealing door 12. The upper side of the top pressure block 15 is in contact with the lower side of the lower pressure plate 10. When the sealing door 12 is closed, the top pressure block 15 presses against the lower side of the lower pressure plate 10, thereby limiting and locking the lower pressure plate 10.

[0030] Please see Figure 1 An observation port 18 is provided on one side of the sealed door 12. A transparent glass 19 is fixedly connected to the inner wall of the observation port 18. The internal condition of the outer box 1 can be observed through the transparent glass 19 in the observation port 18 without opening the sealed door 12.

[0031] The implementation principle of the power distribution switch device for coal mine electromechanical transportation transmission electrical engineering in this application embodiment is as follows: When in use, the spring 20 presses against the locking tongue 8, so that the locking tongue 8 is inserted into the card seat 5 to fix the mounting plate 21 inside, thus realizing operation. When maintenance is required, first open the sealing door 12, press down the lower pressure plate 10 to slide in the control port 9, and drive the locking tongue 8 to hide inside the hidden groove 7. The locking tongue 8 is separated from the card seat 5, and the mounting plate 21 can be pulled out and moved to the outside of the outer box 1, so that the electrical components are exposed on the outside for maintenance. This method can greatly increase the maintenance space and improve the convenience and efficiency of subsequent disassembly and maintenance.

[0032] When pulled to the outermost position, the sliding block 3 will press the push switch 111. After being pressed by the push switch 111, the lighting lamp 112 will be turned on to automatically illuminate both sides of the mounting plate 21. When the sliding block 3 is separated from the push switch 111, the lighting lamp 112 will automatically turn off. This provides sufficient light for maintenance personnel to clearly see the various electrical components inside the device, improving the operability of maintenance.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
