Description

Technical Field

[0001] The present invention belongs to the technical field of alarm devices. Specifically, it particularly relates to a monitoring and alarm device for spontaneous combustion fires in coal mines. Background Art

[0002] A coal mine is an area where humans extract coal resources in coal-rich mining areas. Generally, it is divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, generally, underground roadways are dug to extract coal. A coal mine that excavates coal by digging underground roadways is an underground coal mine, and most coal mines in China belong to underground coal mines. Since underground coal mines need to carry out mining work deep underground, there are certain safety hazards during the mining process; and a monitoring and alarm device for spontaneous combustion fires in coal mines refers to a special device that can monitor the spontaneous combustion status of the coal seam in real time, identify fire hazards, and send out alarm signals in a timely manner during the coal mine mining process to prevent and control fires caused by spontaneous combustion of the coal seam.

[0003] In the prior art, the monitoring and alarm device needs to be monitored for a long time, which causes the temperature inside it to rise. If heat dissipation is not carried out in a timely manner, it may cause the internal electronic components to be damaged due to high temperature. Currently, the heat dissipation method mostly used is to use a filter screen for heat dissipation. However, after the filter screen is used for a long time, a large amount of coal dust, dust and other pollutants will adhere to its surface. If it is not cleaned in a timely manner, it may become blocked, thus affecting the heat dissipation efficiency. However, the existing filter screen is not convenient for disassembly and installation, which makes it extremely troublesome to clean the filter screen. Summary of the Invention

[0004] In view of the problems in the related art, the present invention provides a monitoring and alarm device for spontaneous combustion fires in coal mines to overcome the above-mentioned technical problems existing in the prior related art.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the invention with reference to the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the invention.

[0032] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation of the invention.

[0033] Please refer to Figures 1-7 As shown, the present invention is a monitoring and alarm device for spontaneous combustion fires in coal mines, including a box body 1. The box body 1 is provided with a notch 2, and a filter screen 3 is movably installed in the notch 2. Connecting blocks 4 are fixedly installed on both sides of the filter screen 3. The connecting blocks 4 are snap-connected with clamping blocks 5. The clamping blocks 5 are slidably installed inside a sliding groove 6, and the sliding groove 6 is opened on the box body 1. A round groove 7 is opened inside the box body 1, and a cooling fan 8 is rotatably installed inside the round groove 7. The box body 1 is slidably connected to a fixed plate 9. Protruding blocks 10 are fixedly installed on both sides of the fixed plate 9, and holes 11 are opened in the protruding blocks 10.

[0034] The working principle of the monitoring and alarm device for spontaneous combustion fires in coal mines proposed by the present invention is that when in use, the device is installed at a corresponding position through the protruding blocks 10 and fixed with bolts, thus completing the installation of the fixed plate 9.

[0035] Furthermore, when it is necessary to disassemble and clean the filter screen 3, the operator pulls the clamping block 5 towards the top of the box body 1, so that the clamping block 5 is disengaged from the snap connection with the connecting block 4. At this time, the operator only needs to remove the filter screen 3 for cleaning.

[0036] It is worth noting that when the filter 3 needs to be installed, the operator pulls the block 5 to move toward the top of the box 1, then places the filter 3 inside the slot 2, and then releases the block 5, using the block 5's own gravity to lower it and move it along the inside of the slide groove 6, so that the block 5 and the connecting block 4 form a resisting connection, thereby completing the installation of the filter 3.

[0037] Furthermore, by starting the cooling fan 8, the electronic components inside the housing 1 can be cooled, thereby increasing the efficiency of the cooling.

[0038] In one embodiment, for the above-mentioned fixed plate 9, the fixed plate 9 is provided with a sliding groove 12, and the box body 1 is slidably connected inside the sliding groove 12. One end of a shock-absorbing column 13 is fixedly installed at the bottom of the box body 1, and the other end of the shock-absorbing column 13 is fixedly installed on the fixed plate 9. The shock-absorbing column 13 is provided with a compression spring 14.

[0039] In one embodiment, for the above-mentioned box body 1, a shock absorbing mechanism is provided at the bottom of the box body 1, and the shock absorbing mechanism includes a protruding base block 15 fixedly installed at the bottom of the box body 1, and the protruding base block 15 is rotatably installed with one end of a connecting rod 16, and the other end of the connecting rod 16 is rotatably installed on a sliding block 17.

[0040] In one embodiment, for the above-mentioned shock absorbing mechanism, two groups of shock absorbing mechanisms are provided, and their parts and installation methods are the same. The two sliding blocks 17 are both slidably connected to the rod 18, and the two ends of the rod 18 are fixedly mounted on the protruding base 19, and the protruding base 19 is fixedly mounted on the fixed plate 9.

[0041] In one embodiment, for the above-mentioned sliding blocks 17 , a shock absorbing spring 20 is fixedly installed between the two sliding blocks 17 , and the shock absorbing spring 20 is sleeved on the rod 18 .

[0042] The working principle of the coal mine spontaneous combustion fire monitoring and alarm device proposed in the present invention is that due to the particularity of the coal mine environment, it may be affected by the vibration of the working machinery, thereby causing the box body 1 to vibrate. At this time, the shock absorbing column 13 and the compression spring 14 cooperate with each other to initially offset the generated vibration force, thereby ensuring the normal operation of its internal electronic components.

[0043] It is worth noting that at this time, the box body 1 moves up and down due to vibration. When the box body 1 moves downward, it simultaneously drives the protruding base block 15 to move downward, thereby driving one end of the connecting rod 16 to rotate. At this time, the other end of the connecting rod 16 also rotates, and drives the sliding block 17 to move toward the central axis position of the rod 18, thereby squeezing the shock-absorbing spring 20, thereby offsetting the force generated by the vibration.

[0044] Furthermore, after the above work is completed, the shock-absorbing spring 20 resets, driving the sliding block 17 to move towards both sides of the rod 18, further driving the connecting rod 16 to rotate in the reverse direction, thereby driving the box body 1 to move upward. Furthermore, the up-and-down movement force generated when the box body 1 is vibrated can be reciprocally offset, thus completing the shock-absorbing work and further protecting the normal operation of the internal electronic components.

[0045] In one embodiment, for the above-mentioned box body 1, an alarm lamp 21 is fixedly installed at the top of the box body 1, and a loudspeaker 22 is fixedly installed on the side of the box body 1.

[0046] In one embodiment, for the above-mentioned box body 1, a gas detector 23 and a temperature detector 24 are fixedly installed on the side of the box body 1 away from the loudspeaker 22.

[0047] In one embodiment, for the above-mentioned box body 1, a plate 25 is fixedly installed inside the box body 1. The plate 25 is provided with ventilation holes 26, and there are two plates 25.

[0048] In one embodiment, for the above-mentioned plate 25, a storage battery 31 is movably installed above one of the plates 25, and a data module 27 and a control module 28 are movably installed above the other plate 25.

[0049] The working principle of a coal mine spontaneous combustion fire monitoring and alarm device proposed by the present invention is that the gas detector 23 detects the gas, and at the same time, the temperature detector 24 detects the temperature. When a problem is detected, the gas detector 23 and the temperature detector 24 transmit electrical signals to the data module 27, and then the control module 28 controls the loudspeaker 22 to emit an alarm to remind the staff that a fire has occurred. At the same time, the alarm lamp 21 emits alarm lights so that the staff can notice the fire faster.

[0050] It should be noted that the gas detector 23 mainly detects gases such as carbon monoxide, methane, and ethylene, and checks whether the detected data exceeds the standard.

[0051] In one embodiment, for the above-mentioned box body 1, a box door 29 is rotatably installed on the box body 1. The box door 29 is provided with a transparent observation window 30, and a monitoring device 32 is fixedly installed above the box body 1.

[0052] The working principle of a coal mine spontaneous combustion fire monitoring and alarm device proposed by the present invention is that by opening the box door 29, the internal electronic components of the box body 1 can be repaired. At the same time, the internal situation can be observed through the transparent observation window 30, and the environment of the coal mine can be monitored by using the monitoring device 32.
