Description

Technical Field

[0001] This utility model relates to the technical field of gas concentration monitoring devices, specifically a dustproof protection structure and a gas concentration monitoring device for goaf areas. Background Technology

[0002] In mining, tunnel construction, and other underground engineering activities, safety monitoring of the working environment is crucial, especially in goaf areas. The presence of rock fracturing, dust generated during operations, and various gases not only threatens the health of workers but can also lead to serious safety accidents such as explosions and poisoning. Therefore, effective gas monitoring devices are essential to ensure the safety of underground working environments.

[0003] In existing technologies, traditional gas concentration monitoring devices operate under conditions where the internal ground temperature gradually rises with increasing mining depth. Therefore, cooling fans are typically installed inside the device to reduce the surface temperature of electronic components and prevent shutdowns due to overheating. To prevent dust from entering the device while the fan is cooling, dustproof plates are usually installed at the air inlet to block dust from entering the casing and extend the lifespan of internal electronic components. However, after prolonged use, a large amount of dust accumulates on the surface of the dustproof plates. Since the existing gas concentration monitoring devices have fixed dustproof plate structures, cleaning requires operators to use tools to disassemble them, which is inconvenient for operators and affects maintenance efficiency.

[0004] Therefore, a dust protection structure and a gas concentration monitoring device for goaf areas are needed to solve the problem that the dustproof plate structure of the existing gas concentration monitoring device is relatively fixed, which leads to complicated disassembly and assembly and thus affects maintenance efficiency. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model proposes a dustproof protection structure and a gas concentration monitoring device for goaf areas. By pushing the push block, the plug block is disengaged from the slot, thus eliminating the need for operators to use tools to disassemble the dustproof plate, thereby completing the cleaning. After cleaning, the spring force pushes the plug block back to its original position, making it convenient for operators to use and improving the efficiency of operator maintenance.

[0006] In view of this, on the one hand, the present utility model provides a dustproof protection structure, including a fixed frame, the fixed frame is hinged to the rear side of the housing, an air intake plate is installed on the inner wall of the rear side of the housing, dustproof plates are inserted into the upper and lower sides of the fixed frame, a slot is opened at the bottom of the fixed frame, and a plug block is inserted into the inner wall of the slot.

[0007] Preferably, a sliding groove is provided at the bottom rear side of the housing, a fixing rod is installed on the inner wall of the sliding groove, a spring is sleeved on the outer side of the fixing rod, and a toggle block is installed at the bottom of the plug-in block.

[0008] Preferably, the front side of the lever is slidably connected to the outside of the fixed rod, and the outside of the lever is in contact with the inner wall of the slide groove. One end of the spring is installed at the bottom of the lever, and the other end is installed at the bottom wall of the slide groove.

[0009] Preferably, the inner wall of the fixed frame is provided with multiple mounting slots, and sliders are installed on both the upper and lower sides of the dustproof plate, with the sliders slidably connected to the inner wall of the mounting slots.

[0010] Preferably, a snap-fit ​​groove is provided on the right side of the inner wall of the mounting groove, and a snap-fit ​​head is installed on the right side of the slider, the snap-fit ​​head snapping into the inner wall of the snap-fit ​​groove.

[0011] Preferably, the plug-in block extends through the top of the slide groove, and the dustproof plate is disposed on the rear side of the air intake plate.

[0012] On the other hand, a gas concentration monitoring device for goaf areas includes a housing, and the dustproof protection structure is installed on the rear side of the housing.

[0013] The beneficial effects of this utility model are as follows: by pushing the push block to disengage the plug block from the slot, the dust cover can be cleaned without the operator using tools to disassemble it.

[0024] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] See Figures 1-9 As shown, the present invention provides a dustproof protection structure and a gas concentration monitoring device for goaf areas, including a fixed frame 2, which is hinged to the rear side of the housing 1. An air inlet plate 4 is installed on the inner wall of the rear side of the housing 1. Dustproof plates 3 are inserted into the upper and lower sides of the fixed frame 2. A slot 5 is opened at the bottom of the fixed frame 2, and a plug block 8 is inserted into the inner wall of the slot 5. The plug block 8 penetrates the top of the slide groove 6. The dustproof plate 3 is set on the rear side of the air inlet plate 4, thereby using the dustproof plate 3 to filter dust in the air and reduce dust entering the interior of the housing 1.

[0027] First, the plug-in block 8 is moved downward and disengaged from the inner wall of the slot 5. Then, the operator opens the fixing frame 2 to clean the dustproof plate 3. After cleaning, the plug-in block 8 is driven through the top of the slide 6 and inserted into the inner wall of the slot 5, thereby locking the fixing frame 2 and reducing the dust on the air intake plate 4 during air intake.

[0028] Example 2

[0029] See Figures 1-9As shown, based on Embodiment 1, in order to facilitate the opening of the fixed frame 2 for cleaning the two dustproof plates 3, a sliding groove 6 is provided at the bottom rear side of the housing 1. A fixed rod 7 is installed on the inner wall of the sliding groove 6, and a spring 10 is sleeved on the outer side of the fixed rod 7. A lever 9 is installed at the bottom of the plug-in block 8. The front side of the lever 9 is slidably connected to the outer side of the fixed rod 7, and the outer side of the lever 9 is in contact with the inner wall of the sliding groove 6. One end of the spring 10 is installed at the bottom of the lever 9, and the other end is installed on the bottom wall of the sliding groove 6. Thus, the elastic force of the spring 10 is used to drive the lever 9 to reset, thereby driving the plug-in block 8 at its top to insert into the inner wall of the slot 5 so as to lock the fixed frame 2.

[0030] First, pull the lever 9 and slide it downwards along the outside of the fixing rod 7, while simultaneously squeezing the spring 10. This will cause the insertion block 8 to move downwards and disengage from the inner wall of the slot 5. Then, the operator opens the fixing frame 2 to clean the dustproof plate 3. After cleaning, the fixing frame 2 is reset, and the lever 9 is released. Due to the elasticity of the spring 10, the lever 9 moves upwards to reset, while simultaneously driving the insertion block 8 through the top of the slide groove 6 and inserting it into the inner wall of the slot 5, thereby locking the fixing frame 2. This reduces dust on the air intake plate 4 during air intake, eliminating the need for the operator to use tools to clean the dustproof plate 3, thus improving maintenance efficiency.

[0031] Example 3:

[0032] See Figures 1-9 As shown in Embodiment 2, in order to achieve a modular design for the dustproof plate 3 and reduce the cost of replacement, multiple mounting slots 11 are provided on the inner wall of the fixing frame 2. Slider 12 is installed on both the upper and lower sides of the dustproof plate 3, and the slider 12 is slidably connected to the inner wall of the mounting slot 11.

[0033] When the dustproof plate 3 fails to provide effective dust protection after prolonged use, pull the lever 9 to open the fixing frame 2, then replace the ineffective dustproof plate 3 by pulling it to the right and causing the sliders 12 on both sides to slide along the inner wall of the mounting groove 11 and disengage from the mounting groove 11. After replacement, reset the replaced dustproof plate 3 and fully insert the sliders 12 on both sides into the inner wall of the mounting groove 11. Then, close and reset the fixing frame 2.

[0034] Example 4:

[0035] See Figures 1-9 As shown, based on Embodiment 3, in order to facilitate the installation of the replaced dustproof plate 3 and the fixed frame 2 together, a snap-fit ​​groove 14 is provided on the right side of the inner wall of the mounting groove 11, and a snap-fit ​​head 13 is installed on the right side of the slider 12. The snap-fit ​​head 13 snaps into the inner wall of the snap-fit ​​groove 14.

[0036] When replacing the dust cover 3, since the slider 12 has a locking head 13 installed on its right side, and the locking head 13 is engaged with the inner wall of the locking groove 14, when the dust cover 3 is pulled to the right, the locking head 13 will move along the inner wall of the locking groove 14 and disengage from the locking groove 14. At this time, the dust cover 3 that is not working well can be replaced. After that, it is reset, and the locking head 13 will slide along the inner wall of the locking groove 14. When the dust cover 3 is fully reset, the locking head 13 will be engaged with the inner wall of the locking groove 14. Thus, the locking head 13 increases the stability of the installation between the dust cover 3 and the fixed frame 2, thereby facilitating the subsequent replacement by operators.

[0037] Example 5:

[0038] See Figures 1-9 As shown, based on Embodiment 4, a gas concentration monitoring device for goaf areas is proposed, including a housing 1, with a dustproof protection structure installed on the rear side of the housing 1.

[0039] In actual use, first pull the lever 9 and slide it down along the outside of the fixed rod 7, while squeezing the spring 10. This will cause the plug block 8 to move down and disengage from the inner wall of the slot 5. Then, the operator opens the fixed frame 2 to clean the dust plate 3. After that, the fixed frame 2 is reset and the lever 9 is released. At this time, due to the elasticity of the spring 10, the lever 9 is moved up and reset, while the plug block 8 is driven to pass through the top of the slide 6 and insert into the inner wall of the slot 5, thereby locking the fixed frame 2. This reduces the dust on the air intake plate 4 during air intake, so that the operator does not need to use tools to clean the dust plate 3, thus improving the efficiency of maintenance.

[0040] When the dustproof plate 3 fails to provide effective dust protection after prolonged use, pull the lever 9 to open the fixing frame 2, and then replace the ineffective dustproof plate 3. Pull it to the right and move the sliders 12 on both sides along the inner wall of the mounting groove 11 and disengage it from the mounting groove 11. After replacement, reset the replaced dustproof plate 3 and fully insert the sliders 12 on both sides into the inner wall of the mounting groove 11. Then, close and reset the fixing frame 2.

[0041] When replacing the dust cover 3, since the slider 12 has a locking head 13 installed on its right side, and the locking head 13 is engaged with the inner wall of the locking groove 14, when the dust cover 3 is pulled to the right, the locking head 13 will move along the inner wall of the locking groove 14 and disengage from the locking groove 14. At this time, the dust cover 3 that is not working well can be replaced. After that, it is reset, and the locking head 13 will slide along the inner wall of the locking groove 14. When the dust cover 3 is fully reset, the locking head 13 will be engaged with the inner wall of the locking groove 14. Thus, the locking head 13 increases the stability of the installation between the dust cover 3 and the fixed frame 2, thereby facilitating the subsequent replacement by operators.
