Description

Technical Field

[0001] This utility model relates to the field of explosion-proof technology, and in particular to a double-push rod bidirectional opening high-pressure air chamber device. Background Technology

[0002] With the continuous development of the coal mining industry, coal mine safety has received increasing attention. Gas and coal dust explosions are among the major safety threats faced in underground coal mines, often causing serious casualties and property damage. To effectively prevent and control explosion accidents, explosion-proof technology has emerged.

[0003] In existing technologies, some explosion-proof devices have a relatively simple shock wave receiving method, which can only receive shock wave signals from one direction and has a receiving blind zone. This means that when an explosion occurs in the receiving blind zone, the device cannot sense the shock wave in time, and therefore cannot activate the explosion-proof measures in time, which may allow the explosion flame to spread and cause greater damage. Improvements are needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that some explosion-proof devices in the prior art have a relatively simple shock wave receiving method, which can only receive shock wave signals from one direction and has a receiving blind zone. Therefore, a double push rod bidirectional opening high-pressure air chamber device is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a double-push-rod bidirectional opening high-pressure air chamber device, comprising an anchor rod, a left shock wave receiving plate, a left push rod, a left hanging device, a left triggering device, a lower pressure gauge, a high-pressure air chamber, a powder storage bin, a top beam hanging device, a spray mist surface, a right triggering device, a right push rod, a right hanging device, and a right shock wave receiving plate. The left and right shock wave receiving plates are respectively located on the left and right sides of the device. The left and right push rods are respectively connected to the left shock wave receiving plate and the left triggering device, and the right shock wave receiving plate and the right triggering device. The left and right hanging devices are arranged on the left and right sides of the device and cooperate with the anchor rod. The lower pressure gauge is installed at the bottom of the device and communicates with the high-pressure air chamber. The top beam hanging device is located at the top of the device.

[0006] Preferably, the left push rod and the right push rod are rigid structures.

[0007] Preferably, the high-pressure air chamber is connected to the powder storage bin.

[0008] Preferably, the materials of the left shock wave receiving plate and the right shock wave receiving plate are high-strength alloys.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] 1. In this utility model, the design of the left and right shock wave receiving plates, located on the left and right sides of the device respectively, enables omnidirectional reception of explosion shock waves from different directions. This ensures that shock wave signals can be detected promptly regardless of the direction of the explosion in the tunnel, thereby improving the device's response sensitivity and reliability to explosions and effectively avoiding explosion-proof failure due to blind spots. Simultaneously, the left and right push rods connect the shock wave receiving plates to the triggering device, ensuring that the triggering device can operate quickly and accurately, enabling the timely ejection of the explosion-proof medium, effectively preventing the spread of explosion flames, and minimizing the damage caused by gas explosions.

[0011] 2. In this utility model, the left and right shock wave receiving plates are made of high-strength alloy materials, which have good wear resistance and impact resistance. They can work stably for a long time in the harsh environment of underground coal mines, effectively extending the service life of the device, reducing the frequency of equipment maintenance and replacement due to material damage, reducing the operating costs of coal mining enterprises, and ensuring that the device can play its explosion-proof function normally at critical moments, providing a solid guarantee for safe production in coal mines.

Detailed Implementation

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figure 1As shown, this utility model provides a technical solution: a double-push rod bidirectional opening high-pressure air chamber device, including an anchor rod 1, a left shock wave receiving plate 2, a left push rod 3, a left hanging device 4, a left triggering device 5, a lower pressure gauge 6, a high-pressure air chamber 7, a powder storage bin 8, a top beam hanging device 9, a spray mist surface 10, a right triggering device 11, a right push rod 12, a right hanging device 13, and a right shock wave receiving plate 14. The left shock wave receiving plate 2 and the right shock wave receiving plate 14 are located on the left and right sides of the device, respectively, and the left push rod 3 and the right push rod... 12 is connected to the left shock wave receiving plate 2 and the left triggering device 5, the right shock wave receiving plate 14 and the right triggering device 11 respectively. The left hanging device 4 and the right hanging device 13 are set on the left and right sides of the device and cooperate with the anchor rod 1. The lower pressure gauge 6 is installed at the bottom of the device and is connected to the high-pressure air chamber 7. The top beam hanging device 9 is located at the top of the device. The left push rod 3 and the right push rod 12 are rigid structures. The high-pressure air chamber 7 is connected to the powder storage bin 8. The materials of the left shock wave receiving plate 2 and the right shock wave receiving plate 14 are high-strength alloys.

[0017] In this embodiment, the design of the left shock wave receiving plate 2 and the right shock wave receiving plate 14 located on the left and right sides of the device, respectively, enables the device to receive explosion shock waves from different directions in all directions. This ensures that the shock wave signal can be detected in a timely manner regardless of where the explosion occurs in the roadway, thereby improving the device's response sensitivity and reliability to explosions and effectively avoiding explosion-proof failure due to blind spots. At the same time, the left push rod 3 and the right push rod 12 are connected to the shock wave receiving plate and the triggering device, respectively, ensuring that the triggering device can act quickly and accurately, realizing the timely ejection of the explosion-proof medium, effectively preventing the spread of explosion flames, and minimizing the harm caused by gas explosions. The left shock wave receiving plate 2 and the right shock wave receiving plate 14 are made of high-strength alloy materials, which have good wear resistance and impact resistance, and can work stably for a long time in the harsh environment of underground coal mines. This effectively extends the service life of the device, reduces the frequency of equipment maintenance and replacement due to material damage, reduces the operating costs of coal mining enterprises, and also ensures that the device can perform its explosion-proof function normally at critical moments, providing a solid guarantee for safe production in coal mines.

[0018] The working principle of this embodiment is as follows: During use, installation is the first step. Anchor bolts 1 are used to fix the device below the roadway roof. The left hanging device 4, right hanging device 13, and top beam hanging device 9 work in conjunction with the anchor bolts 1 to ensure the device is stably installed in a suitable position. The top beam hanging device 9 is located at the top of the device, further enhancing its stability. After installation, the left shock wave receiving plate 2 and right shock wave receiving plate 14 are located on the left and right sides of the device, respectively, ready to receive shock waves generated by an explosion. When a gas or coal dust explosion occurs, the shock wave generated will propagate before the flame. The shock wave will act on the left shock wave receiving plate 2 and right shock wave receiving plate 14. Because these two receiving plates are made of high-strength alloy material, they can withstand the impact of the shock wave. The left shock wave receiving plate 2 and right shock wave receiving plate 14... Upon receiving the shock wave, the impact force is transmitted to the connected left push rod 3 and right push rod 12. The left push rod 3 and right push rod 12 are rigid structures, efficiently transmitting force to the left triggering device 5 and right triggering device 11. Upon receiving the force signal, the triggering devices activate, opening the high-pressure gas chamber 7 connected to the lower pressure gauge 6. The lower pressure gauge 6 monitors the pressure within the high-pressure gas chamber 7 in real time. The high-pressure gas chamber 7 is connected to the powder storage bin 8. The high-pressure gas in the high-pressure gas chamber 7 rapidly flows into the powder storage bin 8, pushing the explosion-proof medium within the bin 8 out, forming a spray mist 10. This explosion-proof medium suspends in the air. When the subsequent explosion flame arrives, the mist-like explosion-proof medium extinguishes the flame in time, effectively preventing the explosion flame from spreading in the roadway and ensuring safety in the coal mine. Throughout the process, all components work collaboratively, following predetermined principles and procedures, to effectively prevent gas or coal dust explosions.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
