[0002] In mining operations, vehicle control and monitoring systems play a crucial role in ensuring production safety and improving operational efficiency. Stable operation is essential for accurate control of vehicle dispatching and equipment operation. The chassis, as a core component, must possess reliable protection capabilities. Due to the complex mining environment, the presence of humid air and dust particles can easily cause short circuits, affecting the system's normal operation. Therefore, designing a short-circuit resistant chassis for mining vehicle control and monitoring systems is crucial.

[0003] Existing mine vehicle control and monitoring system chassis offer multiple advantages. In terms of explosion protection, they employ an explosion-proof enclosure design, enabling safe operation in hazardous environments containing methane and coal dust, preventing internal malfunctions from causing external explosions. They also boast a high protection level, effectively preventing dust, water, and moisture damage, thus preventing short circuits caused by dust accumulation and moisture intrusion. Some chassis are also equipped with surge protection modules to reduce damage to internal circuitry from lightning strikes, ensuring stable system operation.

[0004] Although the protection level is high, effectively preventing dust, water, and moisture, and preventing short circuits caused by dust accumulation and moisture intrusion, some chassis are also equipped with surge protection modules to reduce the damage of lightning strikes to internal circuits and ensure stable system operation. However, in the current technology, the filter screen of the chassis body cannot be effectively disassembled. After long-term use, the filter screen will become clogged. If it is not cleaned in time, it will lead to a decline in the performance of the chassis body. When cleaning is required, the staff cannot effectively clean and maintain the filter screen.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A short-circuit protection chassis for a mining vehicle operation monitoring system includes a chassis body. Mounting slots are provided on both sides of the chassis body. Connecting plates are movably mounted inside the upper and lower ends of each mounting slot. Mounting frames are fixedly snapped into the mounting slots on both sides. A filter screen is fixedly mounted inside the inner ring of each mounting frame. Connecting slots are provided on both the upper and lower ends of each mounting frame, and the connecting plates are slidably mounted inside the connecting slots. Multiple short-circuit protection protrusions are integrally formed on one end of the chassis body.

A plug is sleeved on the outer ring of the side of the short-circuit protection protrusion away from the chassis body. Locking slots are provided on both the upper and lower ends of each plug, and the locking blocks are engaged and mounted inside the locking slots.

[0008] As a preferred technical solution, a heat dissipation mesh is fixedly installed inside the end of the chassis body away from the multiple short-circuit protection protrusions, and support feet are fixedly installed around the bottom of the chassis body.

[0009] As a preferred technical solution, both sides of the mounting slots are integrally formed with baffle frames, and one side of the mounting frame is attached to the baffle frame on the side away from the inside of the chassis body.

[0010] As a preferred technical solution, buffer grooves are provided inside both the upper and lower ends of the mounting groove, and multiple buffer springs are fixedly installed inside each buffer groove. The ends of the multiple buffer springs away from the buffer grooves are fixedly installed on the side of the plug-in plate away from the plug-in grooves.

[0011] As a preferred technical solution, the plug-in plate is movably installed inside the upper and lower ends of the mounting slot via the plug-in slot, and a push block is integrally formed on the upper end of one side of the plug-in plate.

[0012] As a preferred technical solution, a groove is provided inside one side of the buffer groove, the push block is slidably installed inside the groove, and the mounting frame is fixed inside the mounting groove by a plug-in plate.

Detailed Implementation

Mounting slots 14 are provided on both sides of the chassis body 7. Connector plates 12 are movably installed inside the upper and lower ends of the mounting slots 14. Mounting frames 4 are fixedly snapped into the mounting slots 14 on both sides. Filter screens 5 are fixedly installed on the inner ring of the mounting frames 4. Connector slots 13 are provided on both the upper and lower ends of the mounting frames 4. Connector plates 12 are slidably installed inside the connector slots 13. Multiple short-circuit protection protrusions 10 are integrally formed on one end of the chassis body 7. Locking blocks 15 are movably installed inside the upper and lower ends of the multiple short-circuit protection protrusions 10. A plug 9 is sleeved on the outer ring of the side of the short-circuit protection protrusion 10 away from the chassis body 7. Locking slots 8 are provided on both the upper and lower ends of the plug 9. Locking blocks 15 are snapped into the locking slots 8.

[0025] refer to Figures 4 to 5 A heat dissipation mesh 1 is fixedly installed inside the end of the chassis body 7 away from the multiple short-circuit protection protrusions 10. Support feet 6 are fixedly installed around the bottom of the chassis body 7. A baffle 11 is integrally formed inside the mounting slots 14 on both sides. The side of the mounting frame 4 is attached to the baffle 11 away from the inside of the chassis body 7. The baffle 11 can effectively limit the position of the mounting frame 4 to prevent the mounting frame 4 from shifting.

[0026] refer to Figures 1 to 5 The mounting slot 14 has buffer slots 19 inside both the upper and lower ends. Multiple buffer springs 18 are fixedly installed inside each buffer slot 19. The ends of the multiple buffer springs 18 away from the buffer slot 19 are fixedly installed on the side of the plug plate 12 away from the plug slot 13. The plug plate 12 is movably installed inside the upper and lower ends of the mounting slot 14 through the plug slot 13. A lever 2 is integrally formed on the upper end of one side of the plug plate 12. A lever 3 is opened inside one side of the buffer slot 19. The lever 2 is slidably installed inside the lever 3. The mounting frame 4 is fixed inside the mounting slot 14 through the plug plate 12. During the installation process, the operator only needs to move the lever 2 integrally formed on the upper end of one side of the plug plate 12 to make the plug plate 12 slide in the lever 3 on the side of the buffer slot 19. Through this simple operation, the plug plate 12 can be easily pulled out from the plug slot 13 of the mounting frame 4, thereby realizing the quick disassembly and replacement of the mounting frame 4. When it is necessary to maintain or replace the filter screen 5, no complicated tools are needed, and the operation can be completed in a short time, which greatly improves the maintenance efficiency.

[0027] refer to Figures 2 to 3The anti-short-circuit protrusion 10 has slots 17 inside both the upper and lower ends. A locking spring 16 is fixedly installed inside the slot 17. The end of the locking spring 16 away from the slot 17 is fixedly installed on one side of the locking block 15. The locking block 15 is movably installed inside the upper and lower ends of the anti-short-circuit protrusion 10 through the spring and the slot 17. When the plug 9 is sleeved on the outside of the anti-short-circuit protrusion 10, the locking spring 16 is in a compressed state, providing an outward elastic force to the locking block 15. Under this elastic force, the locking block 15 can be accurately embedded in the locking slots 8 at the upper and lower ends of the plug 9, realizing a stable connection between the plug 9 and the chassis. This stable connection method has a dual guarantee function. On the one hand, it ensures the stability of the electrical connection. Even in the frequent vibration environment of mining operations, it can prevent the plug 9 from loosening and avoid short circuits caused by poor contact.

[0028] Operating Principle and Advantages: The chassis body 7 serves as the core frame, and the mounting slots 14 on both sides form the basis for modular protection. The plug-in plates 12, which are movably installed at the upper and lower ends of the mounting slots 14, precisely match the plug-in slots 13 at the upper and lower ends of the mounting frame 4, creating a convenient assembly and disassembly system. The filter screen 5 fixed inside the mounting frame 4 is made of high-strength fiber material, and the mesh density is specially designed to effectively intercept common particulate impurities such as dust and slag in the mining environment, preventing these impurities from accumulating inside the chassis and thus avoiding the risk of short circuits caused by impurities. During the installation of the mounting frame 4, the integrally formed baffle frames 11 inside the mounting slots 14 on both sides play an important role. The baffle frames 11 provide precise positioning for the mounting frame 4, ensuring that the mounting frame 4 can be tightly secured. The tightly fitted structure within the mounting slot 14 further enhances the dustproof effect, forming a robust dustproof barrier that comprehensively protects the electronic components inside the chassis. Multiple short-circuit protection protrusions 10, integrally formed at one end of the chassis body 7, are the core highlight of the chassis's short-circuit protection design. The movable locking blocks 15 at the upper and lower ends of the short-circuit protection protrusions 10 work in conjunction with the locking springs 16 within the slots 17 to form the short-circuit protection structure for the connector 9. When the connector 9 is fitted onto the outside of the short-circuit protection protrusions 10, the locking springs 16 are compressed, providing outward elasticity to the locking blocks 15. Under this elasticity, the locking blocks 15 can precisely embed into the locking slots 8 at the upper and lower ends of the connector 9, achieving a stable connection between the connector 9 and the chassis. This stable connection... The connection method provides dual protection. Firstly, it ensures the stability of the electrical connection, preventing the plug 9 from loosening even in the frequent vibrations of mining operations, thus avoiding short circuits caused by poor contact. Secondly, the special shape design of the anti-short-circuit protrusion shell 10 creates a physical isolation space, isolating the plug 9 interface from external humid air, conductive dust, and other short-circuit causes, reducing the likelihood of short circuits at the source. The buffer grooves 19 at the upper and lower ends of the mounting slot 14 and the internal buffer springs 18 provide excellent shock resistance for the chassis. In mining operations, strong vibrations are generated by blasting, heavy equipment operation, etc. When the vibration is transmitted to the chassis, the plug plate 12 can slide along a preset track within the buffer groove 19, buffering the vibration. As the spring 18 compresses and deforms, it absorbs a large amount of vibration energy through its elastic deformation, minimizing the impact of vibration on the internal electronic components and effectively preventing short circuits caused by loose components or broken wires. Simultaneously, the heat dissipation mesh 1, fixedly installed at the end of the chassis body 7 away from the anti-short circuit protrusion 10, combines with the internal heat convection principle to create an efficient heat dissipation channel. During operation, the electronic components continuously generate heat, which naturally rises and is exhausted to the outside of the chassis through the heat dissipation mesh 1. The special mesh design of the heat dissipation mesh 1 ensures effective ventilation and heat dissipation while effectively preventing external debris from entering the chassis, maintaining the internal temperature within the normal operating range of the electronic components.To ensure stable circuit operation, during installation, the operator only needs to move the integrally formed lever 2 on one side of the plug plate 12 to slide the plug plate 12 within the lever 3 on one side of the buffer groove 19. Through this simple operation, the plug plate 12 can be easily pulled out of the plug slot 13 of the mounting frame 4, thus achieving quick disassembly and replacement of the mounting frame 4. When maintenance or replacement of the filter screen 5 is required, no complicated tools are needed, and the operation can be completed in a short time, greatly improving maintenance efficiency. The locking block 15 design on the anti-short-circuit protrusion 10 also facilitates the insertion and removal of the plug 9. During plug 9 disassembly, due to the tight fit between the locking block 15 and the slot 8, there will be no loosening of the interface and the generation of electric sparks, ensuring the safety of the operation. When installing the plug 9, simply slip the plug 9 onto the outside of the anti-short-circuit protrusion 10, and the locking block 15 automatically embeds into the slot 8 under the action of the locking spring 16, achieving a quick and stable connection.
