[0001] This utility model relates to the field of coal mine employee training and drill technology, and in particular to a gas explosion drill device. Background Technology

[0002] Gas explosion drills simulate scenarios where gas mixes with air in places like coal mines and reaches its explosive limit, then explodes upon contact with an ignition source. These drills test the feasibility of emergency plans and improve personnel's emergency response capabilities. When conducting such drills, various devices are required to simulate the real environment, monitor key parameters, and ensure safety.

[0003] Currently, gas detectors are installed in the exercise area during gas explosion drills to monitor the gas concentration, oxygen content, and toxic gases in the exercise area, thereby ensuring the safety of the exercise environment. However, gas detectors are usually placed directly in the exercise area. During a gas explosion, sand and gravel are usually splashed out. Gas detectors that are close to the explosion location are easily damaged by the impact of sand and gravel, affecting their service life. Summary of the Invention

[0004] This invention provides a gas explosion simulation device, in which most of the sand and gravel splashed during a gas explosion are directly blocked by the protective shell, and a small amount of sand and gravel are collected by the air intake hood. It can also prevent sand and gravel from falling into the inner side of the protective shell and colliding with the gas detector, thus extending the service life of the gas detector.

[0005] In a first aspect, this utility model provides a gas explosion simulation device, specifically comprising: a base; a protective shell fixed to the top of the base, a gas detector installed in the middle of the top of the base, and fans installed on both the left and right sides of the top of the base; exhaust pipes fixed to the outer walls of both the left and right sides of the protective shell; an air intake hood welded to the inner side of the top of the protective shell, and a guide plate fixed between the two air intake hoods, with a guide pipe connected to the bottom middle of the guide plate.

[0006] The air deflector is fixed to the bottom of the elongated opening on one side of the air intake hood, and the front and rear outer walls of the air intake hood are welded to the front and rear inner walls of the protective shell.

[0007] The protective housing has two rectangular openings at the top, and the air intake hood is welded into the rectangular openings at the top of the protective housing. The air intake hood also has a groove with a top opening on its inner side.

[0008] The guide tube is located directly above the gas detector, and the distance between the top surface of the gas detector and the bottom surface of the guide tube is 8cm.

[0009] The air intake hood is equipped with an L-shaped plate fixed to the top inner side, and the vertical plate portion of the L-shaped plate is located in the middle of the inner side of the air intake hood. An opening is provided between the bottom end of the L-shaped plate and the bottom inner wall of the air intake hood.

[0010] The fans are located on the left and right sides of the gas detector, and one end of each exhaust pipe extends to the outside of the protective housing.

[0011] The air intake hood has a long strip opening on one side, and the long strip opening is located above the bottom surface of the L-shaped plate inside the air intake hood.

[0012] This utility model provides a gas explosion simulation device, which has the following beneficial effects: The protective shell of this invention can shield and protect the gas detector. The fan and air intake hood work together to allow air in the exercise area to continuously flow into the inner side of the protective shell. The elongated opening on the air intake hood, together with the guide plate and guide pipe, can guide the air to the outside of the gas detector, thereby monitoring the gas concentration, oxygen content and toxic gases in the exercise area, ensuring the safety of the exercise environment.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1: Please refer to Figures 1 to 5 : This utility model discloses a gas explosion drill device, comprising: a base 1; a protective shell 2 fixed to the top of the base 1; a gas detector 3 installed in the middle of the top of the base 1; and fans 4 installed on both the left and right sides of the top of the base 1. The base 1 supports the upper part of the device structure, and the protective shell 2 shields and protects the gas detector 3. The gas detector 3 monitors the gas concentration, oxygen content, and toxic gases in the drill area to ensure a safe drill environment. When the fans 4 are working, they blow air from the inner cavity of the protective shell 2 out through exhaust pipes 5, thereby continuously drawing air from the drill area into the inner side of the protective shell 2. Exhaust pipes 5 are fixed to the outer walls of both the left and right sides of the protective shell 2. When the fan 4 is working, it blows the air in the inner cavity of the protective housing 2 out through the exhaust pipe 5. An air intake hood 6 is welded to the inner top of the protective housing 2, and a guide plate 7 is fixed between the two air intake hoods 6. A guide pipe 8 is connected to the bottom middle position of the guide plate 7. The air intake hood 6 is used to guide the external air into the inner cavity of the protective housing 2. When in use, the air outside the protective housing 2 will first enter the groove inside the air intake hood 6 through the opening at the top of the air intake hood 6. Then the air will flow through the opening at the bottom of the L-shaped plate inside the air intake hood 6 to the long strip opening on one side of the air intake hood 6. Then the air will flow towards the middle position at the top of the guide plate 7. Finally, the air will flow downward through the guide pipe 8 to the outside of the gas detector 3.

[0018] In this embodiment, as Figures 3-5 As shown, the guide plate 7 is fixed to the bottom of the elongated opening on one side of the air intake hood 6, and the front and rear outer walls of the air intake hood 6 are welded to the front and rear inner walls of the protective housing 2. When in use, air will flow through the opening at the bottom of the L-shaped plate inside the air intake hood 6 into the elongated opening on one side of the air intake hood 6. Then the air will flow towards the middle of the top of the guide plate 7. Finally, the air will flow downward through the guide pipe 8 to the outside of the gas detector 3. The guide plate 7 can guide the air.

[0019] In this embodiment, as Figure 1 and Figures 3-5As shown, the protective housing 2 has two rectangular openings at the top. The air intake hood 6 is welded into the rectangular openings at the top of the protective housing 2. The inner side of the air intake hood 6 has a groove for the top opening. Therefore, when in use, the air outside the protective housing 2 will first enter the groove inside the air intake hood 6 through the opening at the top. If sand and gravel splashed out during the explosion fall on this device, the sand and gravel will be collected by the groove inside the air intake hood 6 when it falls inside.

[0020] In this embodiment, as Figure 3 and Figure 4 As shown, the guide tube 8 is located directly above the gas detector 3, and the distance between the top surface of the gas detector 3 and the bottom surface of the guide tube 8 is 8cm. When in use, the air will flow downward through the guide tube 8 to the outside of the gas detector 3, so that the air entering from the outside can come into uniform contact with the gas detector 3, ensuring that the gas concentration, oxygen content and toxic gases in the exercise area can be monitored.

[0021] In this embodiment, as Figures 3-5 As shown, L-shaped plates are fixed to the inner top of the air intake hood 6, and the vertical part of the L-shaped plate is located in the middle of the inner side of the air intake hood 6. An opening is provided between the bottom end of the L-shaped plate and the bottom inner wall of the air intake hood 6. When in use, the air outside the protective housing 2 will first enter the groove inside the air intake hood 6 through the opening at the top of the air intake hood 6. Then the air will flow through the opening at the bottom end of the L-shaped plate inside the air intake hood 6 to the long strip opening on one side of the air intake hood 6. If sand or gravel falls inside the air intake hood 6, it will be collected by the groove inside the air intake hood 6. Moreover, the L-shaped plate inside the air intake hood 6 can also prevent sand or gravel from entering the protective housing 2 and causing collision with the gas detector 3.

[0022] In this embodiment, as Figures 3-5 As shown, the air intake hood 6 has a long strip opening on one side, and the long strip opening is located above the bottom surface of the L-shaped plate inside the air intake hood 6. The long strip opening on one side of the air intake hood 6 allows air to flow into the inner side of the protective shell 2, and the high position of the long strip opening can also prevent sand and gravel from splashing into the inner side of the protective shell 2.

[0023] Example 2, based on Example 1, such as Figures 1-5 As shown, the blowers 4 are located on the left and right sides of the gas detector 3, and one end of the exhaust pipe 5 extends to the outside of the protective housing 2. When the blowers 4 are working, they blow the air in the inner cavity of the protective housing 2 out through the exhaust pipe 5. During the exercise, the air will flow downward through the guide pipe 8 to the outside of the gas detector 3. Therefore, the circulating air can first contact the gas detector 3 before being discharged outward, ensuring that the gas concentration, oxygen content and toxic gases in the exercise area can be monitored. The outward-extending exhaust pipe 5 can also prevent sand and gravel from directly hitting the blowers 4.

[0024] The working principle of this embodiment is as follows: When a gas explosion drill is required for coal mine employees, this device can be installed on the drill site with the support of the base 1. The gas detector 3 and the blower 4 are connected to the external controller and power supply. After the gas explosion, the gas detector 3 and the blower 4 can be turned on. When the blower 4 is working, it will blow the air in the inner cavity of the protective shell 2 out through the exhaust pipe 5. At this time, a negative pressure will be generated in the inner cavity of the protective shell 2. Therefore, the air outside the protective shell 2 will first enter the inner groove of the air intake hood 6 through the opening at the top of the air intake hood 6. Then the air will flow through the opening at the bottom of the L-shaped plate inside the air intake hood 6 to the long strip opening on one side of the air intake hood 6. The air then flows from the top of the guide plate 7 toward the middle of its top, and finally flows down through the guide pipe 8 to the outside of the gas detector 3. This allows the air in the exercise area to continuously flow into the inner side of the protective shell 2, enabling the gas detector 3 to monitor the gas concentration, oxygen content, and toxic gases in the exercise area, ensuring the safety of the exercise environment. Moreover, if sand and gravel splashed out during the explosion fall on this device, the protective shell 2 will block most of the sand and gravel. If any sand and gravel fall inside the air intake hood 6, it will be collected by the groove inside. Furthermore, the L-shaped plate inside the air intake hood 6 can also prevent sand and gravel from entering the protective shell 2 and colliding with the gas detector 3.

[0025] The following points should be noted in this article: 1. The accompanying drawings of this embodiment only involve the structures involved in this embodiment; other structures can refer to the general design.

[0026] 2. Where there is no conflict, this embodiment and the features in the embodiment can be combined with each other to obtain new embodiments.
