Description

Technical Field

[0001] The present invention relates to the technical field of methane alarm devices, and particularly to a protective structure for a methane alarm device. Background Art

[0002] With the improvement of the mining efficiency of mineral resources, mining has gradually penetrated deeper into the earth's strata. Since many mineral resources are associated with methane, during underground mining operations, the methane content often needs to be observed at any time to avoid explosions due to excessive methane content. However, since methane in nature is a colorless and odorless gas at normal temperature and pressure, it is difficult to detect in a timely manner when the methane concentration reaches a dangerous level during mining. Therefore, methane alarm devices are mostly used for monitoring, and the methane alarm device is used to observe the methane concentration in a timely manner. However, due to the harsh mining environment, the methane alarm device is easily damaged underground, resulting in the failure of the methane alarm device and thus losing its monitoring function for methane. Therefore, there is an urgent need for improvement. Summary of the Invention

[0003] The purpose of the present invention is to provide a protective structure for a methane alarm device to improve the protection effect on the methane alarm device and avoid the problem that the methane alarm device is easily damaged underground.

[0004] To achieve the above purpose, the present invention provides a protective structure for a methane alarm device. The protective structure for the methane alarm device includes a protective housing, a filling airbag member, and an alarm device body. The protective housing is sleeved outside the alarm device body, and the filling airbag member is embedded inside the protective housing to prevent sparks from occurring during the opening and closing process of the protective housing. The protective housing includes a bearing box body, an observation door, and a blade member. The bearing box body is arranged outside the alarm device body, the blade member is arranged inside the observation door and is rotatably connected to the observation door. The observation door is rotatably connected to the bearing box body and is arranged on one side of the bearing box body.

[0005] The protective housing protects the alarm device body. Through the setting of the protective housing, it is avoided that the alarm device body is damaged due to collisions and other reasons underground. The filling airbag member cooperates with the observation door, so that when the observation door is closed, the possibility of sparks generated by the collision of the observation door closing against the bearing box body is reduced. The setting of the observation door cooperating with the bearing box body facilitates viewing the data of the alarm device body when needed, so as to facilitate understanding the methane content. The blade member closes the observation door when not in use, thereby preventing impurities and dust from entering the observation door and causing the display data of the alarm device body to be unviewable. At the same time, the blade member also undertakes a certain cleaning work on the residual impurities.

[0006] Among them, the blade member includes a toggle wheel, a plurality of blades and a driven gear set. The toggle wheel is embedded in the inner side of the observation door and is rotatably connected to the observation door. The plurality of blades are arranged on the inner side of the observation door, and the plurality of blades are fixedly connected to the driven gear set and rotate with the rotation of the driven gear. The driven gear set is rotatably connected to the toggle wheel.

[0007] When it is necessary to view the data of the alarm device body, the dial wheel rotates when the user turns it, thereby driving the driven gear set to rotate, causing the blades to rotate as well, thereby revealing the alarm device body. After the view is completed, the dial wheel is rotated in the opposite direction to close the blades, thereby closing the observation door to prevent dust and impurities from entering.

[0008] The driven gear set is provided with a plurality of driven gears and matching wheels, the plurality of driven gears are meshed with each other, and the matching wheels are meshed with the shifting wheel and the driven gears at the same time to transmit the rotation of the shifting wheel.

[0009] The matching wheel is used to transmit the rotation of the dial wheel to the driven gear, and a plurality of the driven gears match a plurality of the blades, so that the plurality of the blades can rotate along with the rotation of the plurality of the driven gears.

[0010] Among them, several of the blades have a dust-removing page with a weighted strip and a rotating rod. The rotating rod is arranged on both sides of the dust-removing page and is rotatably connected to the dust-removing page. The dust-removing page is arranged on the inner side of the blade and is rotatably connected to the blade through the rotating rod. The weighted strip is arranged on one side of the dust-removing page and is fixedly connected to the dust-removing page to drive the dust-removing page to rotate during the rotation of the blade.

[0011] The dust removing page can generate relative rotation with the blade via the rotating rod, and during the rotation of the blade, the dust removing page can be rotated by utilizing the setting of the weighted strip, and the relative rotation between the dust removing page and the blade can be utilized to remove the impurities remaining on the blade.

[0012] Among them, the filling airbag component has a buffer bladder body and multiple shock-absorbing branch components, the buffer bladder body is embedded in the inner side of the protective cover shell, the multiple shock-absorbing branch components are arranged on the side of the buffer bladder body close to the observation door, and the multiple shock-absorbing branch components are all connected to the buffer bladder body.

[0013] The buffer bladder is embedded on one side of the protective housing near the observation door. The buffer bladder and the shock-absorbing branch member cooperate to reduce the possibility of spark generation between the observation door and the protective housing when the observation door is closed, thereby enhancing the safety of underground operations. Both the buffer bladder and the shock-absorbing branch member are made of rubber material. At the same time, the buffer bladder also has a certain noise reduction effect, improving the noise when the observation door and the protective housing are opened and closed.

[0014] Among them, the shock-absorbing branch member has an arc-shaped protrusion and a filling partition. The arc-shaped protrusion is arranged on the side of the shock-absorbing branch member near the observation door and is communicated with the buffer bladder. The filling partition is a honeycomb structure, and the filling partition is arranged inside the arc-shaped protrusion along the length extension direction of the arc-shaped protrusion.

[0015] The arc-shaped protrusion bears the buffering effect on the observation door, and the filling partition assists in enhancing the buffering effect, making the closing of the observation door more stable.

[0016] A methane alarm protection structure of the present invention improves the structure of the methane alarm protection structure and adds the blade member to cooperate with the observation door. Thus, even when used underground, it can effectively prevent impurities in the air from adhering to the alarm body, resulting in the inability to view the methane content. At the same time, it also enhances the protection of the alarm body and effectively extends the service life of the alarm body. BRIEF DESCRIPTION OF THE DRAWINGS

By providing the observation door 5, it is convenient to check the data of the alarm instrument body 3 when needed, so as to understand the methane content. The blade component 6 closes the observation door 5 when not in use, thereby preventing impurities and dust from entering the observation door 5, resulting in the inability to view the displayed data of the alarm instrument body 3. At the same time, the blade component 6 also undertakes a certain cleaning work for residual impurities.

[0032] The blade member 6 includes a toggle wheel 13, a plurality of blades 14 and a driven gear set 15.
