Description

Technical Field

[0001] The utility model relates to the technical field of coal mine safety monitoring, in particular to a protective device for a mine-used hydrogen sulfide monitor. Background Art

[0002] Safety is always a top priority in underground coal mines. Coal mines are filled with a variety of flammable, explosive, and toxic gases, among which hydrogen sulfide (H2S) is a particularly dangerous gas. It is colorless, highly toxic, flammable, and explosive. When its concentration in the air reaches a certain level, it not only poses a serious threat to human health but can also cause explosions, resulting in significant casualties and property losses.

[0003] A portable hydrogen sulfide monitor is a commonly used device in underground coal mine operations. It is usually worn on the body of underground workers via a belt to monitor the concentration of hydrogen sulfide gas in the workers' working area and issue an alarm to remind workers to stay away when the concentration exceeds the warning value. However, due to the complex mine environment during the workers' underground operations, the hydrogen sulfide monitor can easily collide with the outside world, causing damage to the hydrogen sulfide monitor, which is quite inconvenient.

[0004] Therefore, a protective device for a mining hydrogen sulfide monitor has been developed, which can protect the monitor during the underground operation of the workers and prevent the monitor from being damaged by collision with the outside world. Utility Model Content

[0005] In response to the problems existing in the existing technology, the utility model proposes a protective device for a hydrogen sulfide monitor for mining. During the underground operation of the staff, the protective device protects the monitor to prevent the monitor from colliding with the outside world and being damaged. This overcomes the disadvantage that during the underground operation of the staff, the mine environment is complex, which makes it easy for the hydrogen sulfide monitor to collide with the outside world, resulting in damage to the hydrogen sulfide monitor and being relatively inconvenient.

[0006] In view of this, the utility model provides a protective device for a mining hydrogen sulfide monitor, comprising a waist belt, a placement frame, a connecting block, a monitor, a limiting mechanism, and a protective mechanism; the waist belt is slidably connected to the placement frame; the placement frame is connected to the limiting mechanism, the placement frame is engaged with one side of the connecting block via the limiting mechanism, and the other side of the connecting block is provided on the monitor;

[0007] The placing rack is provided with a protection mechanism, the protection mechanism comprises a supporting frame, a buffer frame and first extension springs, the lower side of the placing rack is connected with the supporting frame, the supporting frame is a half-wrapping structure, the monitor is placed in the gap between the supporting frame and the placing rack, the front side of the supporting frame is slidably connected with the buffer frame, and the first extension springs are connected between the buffer frame and the front side of the supporting frame.

[0014] Preferably, the number of the second extension springs is four, and the second extension springs are arranged on the upper side and the lower side of the left end and the upper side and the lower side of the right end of the placing rack.

[0015] The monitor can be protected during the underground operation of the staff, and the monitor is prevented from being damaged due to collision with the outside world.

[0016] 1、when the monitor collides with the outside world during the working process of the underground operation personnel of the coal mine, the buffer frame contacts the outside world first, and the impact on the outside world is buffered under the action of the first extension spring, so that the monitor can be protected during the underground operation of the staff, and the monitor is prevented from being damaged due to collision with the outside world.

[0026] Example 1

[0027] like Figure 1-4 As shown, a protective device for a hydrogen sulfide monitor for mining includes a waist belt 1, a placement frame 2, a connecting block 3, a monitor 4, a connecting belt 5, a limiting mechanism 6, and a protective mechanism 7. The waist belt 1 is a snap-on structure, forming a ring structure, which makes it easy to snap the waist belt 1 and stabilize it at the worker's waist, or to remove it from the worker's body. The left front side of the waist belt 1 is slidably connected to the placement frame 2. The placement frame 2 is connected to a limiting mechanism 6, which is snapped onto one side of the connecting block 3 through the limiting mechanism 6, so that the connecting block 3 can be flexibly connected to or separated from the placement frame 2. The other side of the connecting block 3 is set on the monitor 4, and the monitor 4 is connected to the placement frame 2 through the connecting block 3. A connecting belt 5 is connected between the monitor 4 and the placement frame 2. Preferably, one end of the connecting belt 5 is fixed to the lower part of the monitor 4, and the other end of the connecting belt 5 is fixed to the lower part of the connecting end 3. The connecting belt 5 is made of elastic and stretchable material.

[0028] like Figure 3 As shown, a protective mechanism 7 is also provided on the placement rack 2, and the monitor 4 is placed in the gap formed between the placement rack 2 and the protective mechanism 7. The protective mechanism 7 includes a support frame 71, a buffer frame 72 and a first telescopic spring 73. The support frame 71 is connected to the lower side of the placement rack 2. The support frame 71 is a U-shaped structure. The monitor is placed in the gap between the support frame and the placement rack, and can half-wrap the monitor 4. The buffer frame 72 is slidably connected to the front side of the support frame 71. A first telescopic spring 73 is connected between the buffer frame 72 and the front side of the support frame 71. Preferably, there are four first telescopic springs 73.

[0029] In this embodiment, the protective mechanism 7 can prevent the monitor 4 from being damaged. After the monitor 4 is fixed to the placement rack 2 through the connection end 3, the buffer rack 72 is located on the outside of the monitor 4. When the monitor 4 collides with the outside world during the work of the coal mine workers underground, the buffer rack 72 contacts the outside world before the monitor 4, so that the buffer rack 72 slides on the support rack 71 and buffers the impact of the outside world under the action of the first telescopic spring 73, avoiding the monitor 4 from being directly impacted, thereby protecting the monitor 4 during the workers' underground work and preventing the monitor 4 from being damaged by collision with the outside world.

[0030] Example 2

[0031] The only difference between this embodiment and embodiment 1 is that Figure 5-6 As shown, the limiting mechanism 6 includes a limiting frame 61, a second telescopic spring 62 and a guide plate 63. The two limiting frames 61 are respectively arranged at the left end and the right end of the placement frame 2 close to the monitor 4, and are slidably connected to the placement frame 2. The limiting frame 61 is clamped with the connecting block 3 through the second telescopic spring 62. Preferably, the number of the second telescopic springs 62 is 4, which are respectively arranged on the upper side and the lower side of the left end of the placement frame 2, and the upper side and the lower side of the right end. A guide plate 63 is connected to the placement frame 2, and the two ends of the guide plate 63 are respectively inserted into the limiting frame 61, so that the limiting frame 61 is slidably connected to the guide plate 63. The guide plate 63 guides the limiting frame 61 to prevent the limiting frame 61 from shifting during the sliding process.

[0032] The use process of the protective device of the mining hydrogen sulfide monitor in this embodiment is as follows:

[0033] First, the waistband 1 is put on the waist position of the downhole worker, then the limiting frame 61 is pressed to slide to the inner side of the placing frame 2, the second telescopic spring 62 is extruded and shrunk, the guide plate 63 can guide the limiting frame 61 to prevent the limiting frame 61 from deviating during sliding, then the connecting block 3 on the monitor 4 is clamped on the placing frame 2, then the limiting frame 61 is loosened, the second telescopic spring 62 rebounds, driving the limiting frame 61 to reset and fix the connecting block 3, so as to fix the monitor 4 on the placing frame 2, the placing frame 2 is made to slide on the waistband 1, driving the position of the connecting block 3 and the monitor 4 to be adjusted to a position convenient for the downhole worker to work and take, when the monitor 4 needs to be taken down to check, the limiting frame 61 is pressed to slide inward, the monitor 4 can be taken out to check the real-time concentration of hydrogen sulfide, so that the monitor 4 is fixed and assisted at the same time, the monitor 4 is convenient to take and place, and the monitor 4 is prevented from being lost. At the same time, the checking efficiency of the staff on the monitor 4 is improved, the connecting belt 5 between the placing frame 2 and the monitor 4 can pull the monitor 4 when the monitor 4 is accidentally dropped, avoiding the monitor 4 from being damaged or lost by falling to the ground.
