Description

Technical Field

[0001] The utility model relates to the technical field of carbon monoxide detection, in particular to a coal mine carbon monoxide detection device. Background Technique

[0002] During the coal mining process, due to reasons such as the oxidation and incomplete combustion of coal, a large amount of carbon monoxide will be generated. Carbon monoxide is a colorless, odorless, tasteless, and extremely toxic gas. After being inhaled by the human body, it will cause tissue hypoxia, inhibit tissue respiration, and endanger people's health and safety. Therefore, timely and accurately detecting the carbon monoxide concentration in coal mines is crucial for preventing carbon monoxide poisoning accidents and ensuring the safety of miners. During the coal mining process, a large amount of dust particles will be generated. These dust particles may adhere to the air inlet of the sensor of the carbon monoxide detection device during the air flow process, gradually accumulate, and may cause the air inlet of the sensor to be blocked, thus easily causing the sensor to be unable to accurately collect the carbon monoxide concentration data in the underground environment, and then easily generating potential safety hazards. At the same time, it is also easy to cause damage to the carbon monoxide detection device, increasing the operation cost and maintenance difficulty of the coal mine. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a coal mine carbon monoxide detection device, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A coal mine carbon monoxide detection device includes a detector main body. A sensor is installed on the detector main body. An installation frame is sleeved on the sensor. The installation frame is composed of a base tube, elastic plates, and installation plates. There are four elastic plates, which are symmetrically and fixedly installed at the upper end of the base tube. There are four installation plates, which are respectively fixedly installed at the upper ends of the four elastic plates. Four limiting structures are symmetrically and fixedly installed on the inner wall of the base tube. The limiting structure is composed of an installation rod, a vibration spring, and an installation substrate. There are two vibration springs, both of which are sleeved on the installation rod. There are two installation substrates, which are respectively fixedly installed at the upper and lower ends of the installation rod. A filtering component is movably installed on the four installation rods of the four limiting structures. The filtering component is composed of a base ring and a filter mesh cloth, and the filter mesh cloth is fixedly installed on the inner wall of the base ring.

[0006] Preferably, an air inlet is provided at the lower end of the sensor, and four installation columns are symmetrically and fixedly installed on the lower side of the outer wall of the sensor.

[0007] Preferably, the base tube on the installation frame is sleeved on the sensor, a set hole is provided on the installation plate, and the installation plate is sleeved on the installation column through the set hole.

[0008] Preferably, the limiting structure is located below the sensor, and the mounting substrate is fixedly connected to the inner wall of the base tube.

[0009] Preferably, four mounting holes are symmetrically formed in the base ring of the filtering assembly, and the mounting holes penetrate the base ring up and down.

[0010] Preferably, the base ring is movably mounted on the mounting rod through the mounting holes formed therein, and the base ring is simultaneously located between two vibration springs on the filtering assembly.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] By providing a mounting frame on the sensor and arranging a filtering assembly in the mounting frame, the filtering assembly cooperates with the mounting frame to block external dust particles, thereby preventing the external dust particles from blocking the air inlet on the sensor, further ensuring that the sensor can accurately collect carbon monoxide concentration data in the coal mine underground environment, ultimately reducing potential safety hazards, and at the same time, reducing the probability of damage to the carbon monoxide detection device, thereby reducing the operation cost and maintenance difficulty of the coal mine; by arranging a limiting structure in the mounting frame and movably mounting the filtering assembly on the limiting structure, when the carbon monoxide detection device is vibrated, the filtering assembly receives the vibration force and under the elastic force of the vibration springs on the limiting structure, will move up and down reciprocally, thereby being able to shake off the dust particles attached thereto, and further reducing the probability of the filtering assembly being blocked by dust particles.

[0018] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a coal mine carbon monoxide detection device includes a detector main body 1. A sensor 2 is installed on the detector main body 1. An air inlet 7 is provided at the lower end of the sensor 2. Four mounting posts 6 are symmetrically and fixedly installed on the lower side of the outer wall of the sensor 2. An installation frame 3 is sleeved on the sensor 2. The installation frame 3 is composed of a base tube 8, elastic plates 9 and mounting plates 10. There are four elastic plates 9, which are symmetrically and fixedly installed at the upper end of the base tube 8. There are four mounting plates 10, which are respectively fixedly installed at the upper ends of the four elastic plates 9. The base tube 8 on the installation frame 3 is sleeved on the sensor 2. A sleeve hole 11 is provided on the mounting plate 10. The mounting plate 10 is sleeved on the mounting post 6 through the sleeve hole 11. A filtering component 5 is movably installed on four mounting rods 12 of four limiting structures 4. The filtering component 5 is composed of a base ring 15 and a filter mesh cloth 16, and the filter mesh cloth 16 is fixedly installed on the inner wall of the base ring 15. Four mounting holes 17 are symmetrically provided on the base ring 15 of the filtering component 5. The mounting holes 17 penetrate the base ring 15 up and down. The base ring 15 is movably installed on the mounting rod 12 through the mounting holes 17 provided thereon, and the base ring 15 is simultaneously located between two vibration springs 13 on the filtering component 5. During use, the mounting plate 10 on the installation frame 3 can be sleeved on the mounting post 6 installed on the outer wall of the sensor 2 under the elastic action of the elastic plate 9. During the use process, the base tube 8 and the filtering component 5 can block external dust particles, thereby preventing external dust particles from blocking the air inlet 7 on the sensor 2, and further ensuring that the sensor 2 can accurately collect carbon monoxide concentration data in the coal mine underground environment, ultimately reducing potential safety hazards, and at the same time, it can also reduce the probability of damage to the carbon monoxide detection device, thereby reducing the operation cost and maintenance difficulty of the coal mine.

[0020] Further, four limiting structures 4 are symmetrically and fixedly installed on the inner wall of the base tube 8. The limiting structure 4 is composed of a mounting rod 12, a vibration spring 13 and a mounting substrate 14. There are two vibration springs 13, both of which are sleeved on the mounting rod 12. There are two mounting substrates 14, which are respectively fixedly installed at the upper and lower ends of the mounting rod 12. The limiting structure 4 is located below the sensor 2, and the mounting substrate 14 is fixedly connected to the inner wall of the base tube 8. When the carbon monoxide detection device is vibrated, the filtering assembly 5 will move on the mounting rod 12 of the limiting structure 4 under the vibration force. At the same time, under the elastic force of the vibration spring 13 on the limiting structure 4, the moving frequency of the filtering assembly 5 will increase. Thus, the dust particles attached to the filter mesh 16 can be shaken off at this time, and further the probability of the filter mesh 16 on the filtering assembly 5 being blocked by dust particles can be reduced.
