Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a methane detection device for mining. Background Art

[0002] In the mine, in order to prevent the methane concentration from being too high and causing explosions, which would endanger the lives of the workers underground, a methane sensor needs to be installed to detect the methane concentration in real time. Figure 1 As shown, the existing methane sensor cable interface is in a vertical position. Due to the large amount of water vapor in the tunnel, it is easy to condense on the top of the sensor. The cable interface in a vertical position is prone to water ingress and short circuit. In addition, existing methane sensors such as laser methane sensors and catalytic methane sensors can only be connected to laser probes and catalytic probes respectively. However, the optimal application environments of the two are different. When the application environment changes, it may lead to poor detection results. The existing gas sensor probe and the junction box shell are connected by threads, and there is a wire in the middle. When it is rotated at will, it may cause circuit wiring problems and cause equipment failure. Utility Model Content

[0037] Real-time detection of methane gas concentration in mines plays a vital role in mine safety. However, the cable interface of conventional methane sensors is often vertically set at the top of the device. Due to the large amount of water vapor in the tunnel, water vapor condenses on the top of the sensor, causing water ingress to the cable interface and causing damage. In addition, existing sensors cannot adjust the detection method according to changes in the application environment. Furthermore, workers are prone to accidentally touch the circuit connector during inspections, causing equipment failure.

[0038] In view of this, the present invention provides a mining methane detection device, which includes a main body 100, a connector 200 and a baffle 600;

[0039] The connector 200 is disposed on the side wall of the main body 100 along the horizontal direction;

[0040] The baffle 600 is disposed on the upper portion of the connecting head and is fixedly connected to the main body 100;

[0041] The baffle 600 gradually slopes downward from one side close to the main body 100 to the other side.

[0042] The connector 200 of the device is arranged on the side wall of the main body 100, and a baffle 600 is arranged on the upper part of the connector 200, which can effectively prevent the condensed water vapor on the top of the main body 100 and the top of the tunnel from flowing into the interface of the connector 200 and causing short circuit and other faults.

[0043] The following will be combined Figure 1 and Figure 2 Detailed description of this plan:

[0044] This solution provides a mining methane detection device, which includes a main body 100, a connector 200 and a baffle 600;

[0045] The connector 200 is disposed on the side wall of the main body 100 along the horizontal direction;

[0046] The baffle 600 is disposed on the upper portion of the connecting head and is fixedly connected to the main body 100;

[0047] The baffle 600 gradually slopes downward from one side close to the main body 100 to the other side;

[0048] One end of the connector 200 away from the main body 100 is sleeved with the cable 500 .

[0049] Preferably, the side walls of the main body 100 also have a certain curvature so that the water vapor attached to the side walls can be discharged in time. Of course, the top of the main body 100 can also be set with a certain curvature to connect with the side walls to facilitate the discharge of water vapor on the top; the connecting head 200 is connected to the main body 100 by means of threads or slots to facilitate installation and disassembly; in order to facilitate carrying and installation, the main body 100 can be made of lightweight materials, such as ABS plastic, etc. In addition, a handle can be set on the top of the main body 100 to facilitate workers to hold it. At the same time, the shape and size of the main body 100 can also be customized according to actual needs.

[0050] like Figure 1 and Figure 2 As shown, it also includes a detection component 300;

[0051] The detection assembly includes a detection head 310 and a safety pin 400;

[0052] The detection head 310 is disposed at the lower part of the main body 100 and is detachably connected to the main body 100;

[0053] The safety pin 400 is plugged into the main body 100 and abuts against the side wall of the detection head 310 .

[0054] When the safety pin 400 is inserted into the main body 100, it contacts the side wall of the detection head 310, thereby locking the detection head 310 to prevent workers from operating it incorrectly during daily inspections or debugging of equipment, which may cause equipment connection failure and lead to detection failure. The detachable connection between the detection head 310 and the main body 100 allows workers to replace different models according to the use environment to improve the detection effect.

[0055] Preferably, the outer dimensions of the main body 100 are larger than those of the detection head 310, so that the main body 100 provides a shielding effect for the detection head 310, thereby preventing the detection head 310 from being hit by debris falling in the mine. In addition, the side walls of the main body 100 can also be made in a form that gradually inclines outward from top to bottom, thereby facilitating the flow of water vapor and increasing the cross-section of the main body 100, thereby protecting the detection head 310 from damage to a greater extent.

[0056] A circuit is arranged inside the main body 100, one end of which is connected to the connector 200, and the other end is connected to the detection component 300; the end of the connector 200 away from the main body 100 is connected to the cable 500 for providing power to the device.

[0057] like Figure 1 As shown, the main body 100 is provided with a display 110;

[0058] A protective cover is provided outside the display 110;

[0059] The protection cover is threadedly connected to the side wall of the main body 100 .

[0060] Specifically, the detection head 310 can detect the concentration of methane in real time and input the data into the display 110. Workers can see information such as the concentration of methane and ambient humidity through the display 110. When it is detected that the methane concentration exceeds the standard, the device will automatically alarm to remind workers to take corresponding measures.

[0061] The beneficial effects of this program are analyzed as follows:

[0062] The mining methane detection device provided in this embodiment has the advantages of simple structure, convenient operation and high reliability. The connection head 200 is arranged on the side wall of the main body 100 and the baffle 600 is used to provide shielding for the connection head 200, which can effectively prevent the condensed water vapor from entering the main body 100 through the connection head 200 and causing a short circuit. The main body 100 and the detection head 310 are detachably connected, which is convenient for timely replacement of different types of detection heads 310 according to changes in the use environment, thereby improving the detection effect. The safety pin 400 is used to lock the connection head between the main body 100 and the detection head 310, thereby avoiding the problem of affecting the detection effect after the detection head 310 is loosened.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of each embodiment of the utility model.
