Description

Technical Field

[0001] This utility model relates to the field of coal mine safety escape technology, and in particular to a coal mine safety escape device. Background Technology

[0002] A coal mine is an area where humans extract coal resources from coal-rich geological strata, typically including facilities such as roadways, shafts, and working faces. Based on different mining methods, coal mines are mainly divided into two categories:

[0003] Underground coal mines: When the coal seam is far from the surface, mining is carried out by excavating tunnels underground.

[0004] Open-pit coal mines: When the coal seam is close to the surface, the surface soil layer is directly stripped away for excavation. This method is suitable for gently sloping or inclined deposits.

[0005] The underground environment of coal mines is harsh, potentially containing flammable and explosive substances such as coal dust and methane gas. Exposure to a source of ignition or electrical discharge can easily lead to explosions. The high humidity and temperature underground, along with various types of groundwater, increase the risk of occupational diseases for miners. The confined working space and poor ventilation further exacerbate safety hazards. Coal mining is a high-risk industry; thorough preparation is essential before entering the mine, including wearing safety equipment and avoiding carrying flammable materials. Major natural hazards underground include water, fire, methane gas, dust, and roof collapses. Therefore, working underground in coal mines is indeed highly dangerous, and miners must strictly adhere to safety regulations to ensure their safety.

[0006] A search revealed that Chinese patent application number 202421258856.4 discloses a coal mine safety escape device, including a steel structure safety support. An arc-shaped protective top is fixedly installed at the top of the steel structure safety support. An escape passage is fixedly installed inside the steel structure safety support. Several escape ladders are fixedly connected inside the escape passage. An air intake fan is fixedly installed at the top of the steel structure safety support. A protective mesh plate is installed on one side of the air intake fan. The air intake fan is signal-connected to a main control board. A vibration sensor is signal-connected to the main control board. A disassembly / assembly base is fixedly installed at one end of the vibration sensor. A fixing block is fixedly installed inside the disassembly / assembly base.

[0007] The safety escape devices described in the aforementioned documents have the following shortcomings: there is only one escape ladder, which will delay escape time if there are many people trying to escape; there are no emergency lights inside the escape passage, so people cannot observe the surrounding safety situation; and there are no emergency safety cabinets inside the escape passage, so emergency equipment or food cannot be retrieved in case of special circumstances.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0033] A coal mine safety escape device, such as Figure 1 , Figure 4 As shown, the system includes a safety escape cabin 1, a lightweight stainless steel magnetic protective net 7, columns 8, a safety steel metal bracket 2, a safety metal escape door 3, and magnetic blocks 11. The top of the safety escape cabin 1 is equipped with a lightweight stainless steel magnetic protective net 7 that can be pushed open. The magnetic blocks 11 are fixedly installed on the side wall of the columns 8. Four columns 8 are fixed to the top of the safety escape cabin 1. The safety steel metal bracket 2 is fixed as one piece to the bottom of the safety escape cabin 1. The safety metal escape door 3 is installed inside the safety steel metal bracket 2 through door hinges.

[0034] In a specific embodiment of this utility model, when encountering danger in a coal mine, one can leave through the safety metal escape door 3 and escape to the ground by opening the lightweight stainless steel magnetic protective net 7, thus protecting the life safety of the escaped personnel.

[0035] To address the situation where lights go out and escape doors are hard to find in coal mines, such as... Figure 1 As shown, it includes a voice-activated lighting lamp 4, which is fixedly installed on the upper side wall of the safety steel metal bracket 2.

[0036] In a specific embodiment of this utility model, when the lights in the coal mine suddenly go out and the safety metal escape door 3 cannot be found, the voice-activated lighting 4 will light up via voice control, so that the escapers can find the safety escape door 3 in the dark.

[0037] To address the problem of survivors encountering slippery rocks during their escape, such as Figure 1 , Figure 2 As shown, it includes a spring bracket 5 and an arc-shaped protective top 6. The spring bracket 5 is fixed to the top of the safety steel metal bracket 2 and has elastic deformation. The arc-shaped protective top 6 is fixed to the top of the spring bracket.

[0038] In a specific embodiment of this utility model, if a tumbleweed falls during the escape process, the escapee can be protected by the arc-shaped protective top 6. If a slightly larger tumbleweed falls, the stone will land on the arc-shaped protective top 6, and the weight of the stone can be buffered by the elastic deformation of the spring bracket 5, thus protecting the escapee from being hit by the tumbleweed.

[0039] To address the issue of safe escape for those fleeing, such as Figure 3 As shown, it includes an escape ladder 10 and a voice-activated light 12. The escape ladder 10 is fixed to the inner wall of the safety escape cabin 1, and the voice-activated light 12 is fixed to the inner wall of the safety escape cabin 1.

[0040] In a specific embodiment of this utility model, after the escape personnel enter the safety escape cabin 1, they can escape according to the escape stairs 10, which have four escape stairs 10, reducing the escape time when there are many people. The inner wall of the safety escape cabin 1 is also fixed with a voice-activated light 12, which can be turned on by voice to illuminate the escape route for the escape personnel to escape safely, thus ensuring the safety of the escape personnel during the escape process.

[0041] To solve the problem of rainwater entering the cabin on rainy days, such as Figure 1 As shown, it includes an arc-shaped protective top 9 and a column 8. The arc-shaped protective top 9 is fixed to the top of the column 8, and the column 8 is fixed to the top of the safety escape cabin 1, with the top of the safety escape cabin 1 being higher than the ground.

[0042] In a specific embodiment of this utility model, if the weather is hot, the arc-shaped protective top 9 can shield the escapee from a large amount of rainwater, preventing hydroplaning during the escape process. It also reduces the amount of rainwater entering the cabin, thus achieving the effect of waterproofing the cabin.

[0043] To address the impact of the impact of danger on escaping personnel, such as Figure 5 As shown, it includes a door pin bracket 14 and a door pin 15. The door pin bracket 14 and the door pin 15 are adapted to each other, and the door pin 15 is movably installed in the door pin bracket 14. The safety steel metal bracket 2 is provided with a pin hole adapted to the door pin 15.

[0044] In a specific embodiment of this utility model, when the impact force from a danger poses a safety problem to the escapees inside the cabin, the escapees can lock the safety metal escape door 3 inside the cabin using the door pin 15, thus preventing the impact force from harming the escapees.

[0045] To solve the problem of escapees being trapped inside the cabin, such as Figure 3 As shown, it includes an emergency safety cabinet 13, which is fixed to the bottom of the inner wall of the safety escape cabin 1.

[0046] In a specific embodiment of this utility model, if a person is trapped in the safety escape cabin 1 in a special situation, the person can retrieve safety tools, food, etc. from the emergency safety cabinet 13 and wait for rescue inside the cabin, thus ensuring the safety of the person inside the cabin.

[0047] To address the issue of stopping to rest on the ladder due to exhaustion while climbing, such as... Figure 3 , Figure 6 , Figure 7 As shown, it includes a safety cage frame 16, a first slot 17, a safety spring buckle 18, and a second slot 19. The safety cage frame 16 is fixed to the side wall of the escape ladder 10, and the first slot 17 is provided on the safety cage frame 16. The safety spring buckle 18 is placed inside the emergency safety cabinet 13, and the second slot 19 is fixed to the inner wall of the safety spring buckle 18.

[0048] In a specific embodiment of this utility model, when an escapee is climbing the ladder, one end of the safety rope can be connected to the upper handle of the safety spring buckle 18, and the other end of the safety rope can be connected to the escapee's belt. Then, the escape ladder 10 can be climbed. The safety cage 16 can ensure the safety of the person climbing the ladder. If the person is too weak to climb the ladder, the safety spring buckle 18 can be pressed down to open the buckle due to the elastic deformation of the spring and lock it into the slot 17 of the safety cage 16. This allows the U-shaped structure of the slot 19 to lock into the opening structure of the slot 17. To release the buckle, the safety spring buckle 18 can be pressed down by hand, thus providing a safety guarantee when resting while climbing the ladder.

[0049] Working principle: In the event of danger inside the coal mine, escapees can use voice control to activate the voice-activated lighting 4 to locate the safe metal escape door 3. The safety steel metal support 2 is equipped with an arc-shaped protective top 6 and a spring support 5. When a rock falls onto the arc-shaped protective top 6, the spring support 5 will be compressed downwards according to its elastic deformation, buffering the force generated by gravity. After entering the cabin, the voice-activated lighting 12 will illuminate the escape route. Escapees can then retrieve the safety spring clip 18 from the emergency safety cabinet 13 and climb the escape ladder 10. If escapees need to rest on the ladder due to exhaustion, a safety device is also provided. The cage frame 16 has a U-shaped structure on the safety cage frame 16 with a slot 19 and an O-shaped structure on the safety spring buckle 18 with a slot 17, which interlocks to ensure the safety of the escaped personnel when resting. When the escaped personnel reach the top of the cabin, they can push the lightweight stainless steel magnetic protective net 7 upwards to make it adhere to the magnetic block 11 on the column 8, and then escape safely. The arc-shaped protective top 9 can block a large amount of rainwater inside the cabin, solving the safety hazard of escaped personnel in rainy weather. If an escaped personnel is trapped inside the cabin in an emergency, they can obtain safety tools, food, etc. from the emergency safety cabinet 13 and wait for rescue inside the cabin. This is a coal mine safety escape device.
