Description

Technical Field

[0001] This utility model relates to the technical field of smoke sensor devices, specifically a dustproof mine smoke sensor. Background Technology

[0002] Smoke sensors can monitor smoke in the air underground in coal mines in real time. Once the smoke concentration reaches the set threshold, the sensor will respond immediately and issue an alarm signal in a timely manner to remind underground workers to take measures, such as organizing evacuation and activating fire extinguishing equipment, thereby effectively preventing the spread of fire accidents and protecting the lives and property of personnel.

[0003] To prevent external dust from entering the sensor, a dust cover is usually installed at the sensor. Over time, a large amount of dust accumulates on the surface of the dust cover, which seriously affects its light transmittance and air circulation. This hinders the smoke from reaching the sensor's detection area, reduces the sensor's response speed and sensitivity to smoke, and makes it difficult to detect smoke in the early stages of a fire in a timely and accurate manner, delaying the best early warning opportunity. At the same time, during long-term use, the dust cover may age, break, or have its dustproof performance reduced due to dust erosion, which will affect the dustproof effect of the dust cover. In view of the shortcomings of existing technology, we propose a dustproof mine smoke sensor to solve the above problems. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model discloses a dustproof mine smoke sensor.

[0025] According to the appendix Figure 1-6As shown, the device includes a mounting base 1, which is fixedly installed on the top of the underground wall. A sensor body 2 is located at the bottom of the mounting base 1 and is fixedly connected to the mounting base 1 via a locking component 3. A dust cover 4 is installed at the bottom of the sensor body 2 and fits onto the outer periphery of the bottom of the sensor body 2. A cleaning component 5 is installed at the dust cover 4 to clean the dust from its surface. Before use, the sensor body 2 is first fixedly installed at the bottom of the mounting base 1 using the locking component 3. During use, the sensor body 2 can monitor the smoke in the underground coal mine air in real time. Once the smoke concentration reaches the set threshold, the sensor body 2 will immediately respond and issue an alarm signal to remind the underground workers to take measures, such as organizing evacuation and activating fire extinguishing equipment, thereby effectively preventing the spread of fire accidents and ensuring the safety of personnel and property.

[0026] The cleaning component 5 includes a drive motor 501 and a cleaning scraper 502. The drive motor 501 is detachably installed at the bottom of the dust cover 4. The cleaning scraper 502 is rotatably sleeved on the outer periphery of the dust cover 4. The output end of the drive motor 501 and the cleaning scraper 502 are detachably connected. During use, the dust cover 4 can prevent external dust and insects from entering the interior of the housing 202 and affecting the sensing probe 203, thus affecting the sensing performance of the sensing probe 203. The dust is blocked on the outer surface of the dust cover 4. At the same time, with the cooperation of the drive motor 501, the cleaning scraper 502 is driven to rotate on the surface of the dust cover 4, thereby scraping off the dust on the surface of the dust cover 4, realizing automatic cleaning, preventing the dust from accumulating and clogging the dust cover 4, preventing smoke from entering the interior of the housing 202, and maintaining the normal detection and alarm functions of the sensor body 2.

[0027] The sensor body 2 includes a sensor body 201, a housing 202, a sensing probe 203, and an alarm light 204. The sensing probe 203 and the housing 202 are both fixedly installed at the bottom of the sensor body 201. The alarm light 204 is fixedly installed on the outer peripheral wall of the sensor body 201. The housing 202 is sleeved on the outer peripheral wall of the sensor body 201. After long-term use, when the dust cover 4 develops holes, it needs to be replaced in time to avoid affecting the normal use of the dust cover 4. When replacing it, the dust cover 4 is rotated to disengage the second threaded ring 403 at the top of the dust cover 4 from the inside of the threaded sleeve 401, thus separating the dust cover 4 from the sensor body 2. Then, the drive motor 501 and the cleaning scraper 502 are removed from the dust cover 4 respectively. The drive motor 501 and the cleaning scraper 502 are then installed with the new dust cover 4 to maintain the dust cover 4's good dustproof performance and appearance.

[0028] The locking assembly 3 includes a locking ring 301, a drive knob 302, a bidirectional screw 303, a drive member 304, and a locking plate 305. The locking ring 301 is fixedly installed on the top of the sensor body 201 and inserted into the mounting base 1. The bidirectional screw 303 is rotatably connected to the top of the mounting base 1. The drive member 304 is slidably sleeved on the outer peripheral walls on both sides of the bidirectional screw 303. The locking ring 301 is aligned with the mounting base 1 and inserted inside. Rotating the drive knob 302 causes the bidirectional screw and 303 to rotate, thereby causing the two sets of drive members 304 to slide away from each other, so that the locking plates 305 are inserted into the locking ring 301 and the mounting base 1, thus fixing the sensor body 2 to the mounting base 1. The locking plate 305 is fixedly installed on the bottom of the drive member 304. One end of the locking plate 305 passes through the locking ring 301 and is inserted into the mounting base 1. When installing the drive motor 501 and the dust cover 4, the drive motor 501 is picked up so that the threaded post 5012 at the bottom of the drive motor 501 passes through the through hole 6, and the drive motor 501 is rotated so that the first threaded ring 5011 at the bottom of the drive motor 501 is threaded into the first threaded cylinder 5013, thereby fixing the drive motor 501 inside the dust cover 4. Then, the cleaning scraper 502 is picked up so that the second threaded cylinder 5014 at the bottom end of the cleaning scraper 502 is threaded onto the outer peripheral wall of the threaded post 5012, thus realizing the installation work between the cleaning scraper 502, the dust cover 4 and the drive motor 501 without the need to replace the drive motor 501 and the cleaning scraper 502, improving the utilization rate of the drive motor 501 and the cleaning scraper 502.

[0029] A threaded sleeve 401 is fixedly connected to the bottom of the sensor body 201, and a mounting plate 402 is fixedly connected to the top of the dust cover 4. A second threaded ring 403 is fixedly connected to the top of the mounting plate 402. The second threaded ring 403 is threadedly connected to the inside of the threaded sleeve 401. A through hole 6 is opened in the middle of the inner part of the dust cover 4. A first threaded cylinder 5013 is fixedly connected to the bottom of the inner part of the dust cover 4. The first threaded cylinder 5013 is located around the through hole 6.

[0030] A first threaded ring 5011 is fixedly connected to the bottom of the drive motor 501. The first threaded ring 5011 is threadedly connected to the inside of the first threaded cylinder 5013. A threaded post 5012 is fixedly connected to the output end of the drive motor 501. The surface of the cleaning scraper 502 is set as a brush. The brush contacts the surface of the dust cover 4. With the cooperation of the drive motor 501, the brush is driven to rotate on the surface of the dust cover 4, thereby enabling the brush to clean the dust on the surface of the dust cover.

[0031] The bottom of the dust cover 4 is provided with a second threaded cylinder 5014. The threaded post 5012 passes through the through hole 6 and is threaded into the inside of the second threaded cylinder 5014. One end of the cleaning scraper 502 is fixedly connected to the second threaded cylinder 5014. The bottom of the second threaded cylinder 5014 is fixedly connected with a connecting shaft 5015.
