DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] like Figure 1 , Figure 2 As shown, a coal mine disaster relief device includes a vehicle body 101, the vehicle body 101 is provided with a plurality of wheels, a transfer box 102 for transferring gas is fixedly installed on the vehicle body 101, an exhaust pipe 103 is fixedly installed on one side of the transfer box 102, an intake pipe 104 is fixedly installed on the end of the transfer box 102 away from the vehicle body 101, the exhaust pipe 103 is connected to the gas exhaust pipeline, and the vehicle body 101 is connected to the intake pipe, a temperature control module 106 is arranged in the transfer box 102, and the temperature control module 106 is used to heat or reduce the air temperature, a transfer pipe 105 is fixedly installed on the side of the transfer box 102 opposite to the exhaust pipe 103, and the outer wall of the transfer pipe 105 A variety of gas detection devices are arranged on it. A gas monitoring module 107 for detecting gas is fixedly installed in the transfer pipe 105. An airflow driving module 110 is arranged on the inner wall of the transfer pipe 105. The airflow driving module 110 is used to drive the airflow to flow. After the airflow driving module 110 is started, it drives the airflow to enter from the transfer pipe 105, and then the airflow passes through the detection of the gas monitoring module 107, and then the airflow flows into the transfer box 102. Therefore, when there is no harmful gas and the device needs to perform normal ventilation work, the gas is discharged through the exhaust pipe 103, and the injection of fresh air into the mine makes the airflow driving module 110 rotate in the opposite direction, and then the exhaust pipe 103 is closed and the vehicle body 101 is opened.

[0023] like Figures 3 to 8 As shown, a support tube 201 is also fixedly installed on the vehicle body 101, a sliding ring 214 is slidably installed on the outer wall of the support tube 201, a main motor 202 is also fixedly installed on the outer wall of the support tube 201, a driving screw 213 is fixedly installed on the output shaft of the main motor 202, the driving screw 213 is rotatably connected to the outer wall of the support tube 201, the driving screw 213 is threadedly connected to the sliding ring 214, a plurality of extrusion sliders 206 are fixedly installed on the sliding ring 214, the extrusion sliders 206 are slidably connected to the support tube 201, and the extrusion sliders 206 are evenly distributed on the support tube 201, a plurality of first swing rods 208 are rotatably installed on one end of the support tube 201 away from the sliding ring 214, a restoring torsion spring is fixedly installed on the first swing rod 208, and the other end of the restoring torsion spring is fixedly installed The first swing rod 208 is fixedly installed on the outer wall of the support tube 201, and two arc-shaped connecting parts are arranged on the first swing rod 208. An inner rubber ring 209 is fixedly installed on the other end of the arc-shaped connecting part. The inner rubber ring 209 is made of rubber material. One end of the inner rubber ring 209 close to the support tube 201 contacts the support tube 201. The first swing rod 208 forms an angle with the end surface of the support tube 201. The end of the first swing rod 208 away from the support tube 201 is rotatably installed with a second swing rod 210. An outer rubber ring 211 is fixedly installed on the second swing rod 210. The outer rubber ring 211 is made of rubber material. One end of the outer rubber ring 211 contacts the inner rubber ring 209. A swing rod torsion spring 212 is fixedly installed on the second swing rod 210, and the other end of the swing rod torsion spring 212 is fixedly installed on the inner rubber ring 209.

[0024] like Figures 3 to 5 As shown, a steel cable 205 is fixedly installed at one end of the second swing rod 210 away from the outer rubber ring 211, and a steel cable ring 204 is fixedly installed at the other end of the steel cable 205. The steel cable ring 204 slides with the outer wall of the support tube 201, and a main cylinder 203 is fixedly installed on the outer wall of the support tube 201. The moving end of the main cylinder 203 is fixedly connected to the steel cable ring 204, and the steel cable 205 is slidably connected to the extrusion slider 206. The steel cable 205 is also slidably connected to the first swing rod 208. When the steel cable ring 204 is driven, the steel cable ring 204 will drive multiple steel cables 205 to move, and the steel cable 205 pulls the second swing rod 210 to rotate, thereby changing the angle between the second swing rod 210 and the first swing rod 208. In the initial state, the angle between the second swing rod 210 and the first swing rod 208 is one hundred and eighty degrees.

[0025] Working principle: When in use, the position of the device is changed by the wheels on the vehicle body 101. There are two ways of using the device. One is that the exhaust pipe 103 needs to be connected to the gas exhaust pipeline, and the vehicle body 101 needs to be connected to the air intake pipeline. The other is that the device is moved in the mine. In this state, the device can only accelerate the air circulation and detect the air. The device drives the airflow through the airflow driving module 110. In the initial state, the airflow driving module 110 can drive the airflow at the support pipe 201 to flow together, and the airflow passes through the transfer pipe 105, the transfer box 102, the exhaust pipe 103 or the vehicle body 101 during the flow.

[0026] After the rotation speed of the airflow driving module 110 of the device reaches the highest, if the airflow ejected by the device needs to affect a farther airflow, the main motor 202 can be used to drive the sliding ring 214 to move, and the sliding ring 214 can drive the extrusion slider 206 to squeeze the first swing rod 208. After the first swing rod 208 is squeezed by the extrusion slider 206, the first swing rod 208 reduces the angle between the first swing rod 208 and the end face of the support tube 201. At the same time, the main cylinder 203 can also be started to drive the steel cable ring 204 to move, so that the steel cable ring 204 changes the angle between the second swing rod 210 and the first swing rod 208 through the steel cable 205. When it is necessary to accelerate the airflow, the angle between the second swing rod 210 and the first swing rod 208 is reduced. In this way, when it is adjusted to the extreme position, Figure 8 In the state shown, the inner diameter of the support tube 201 is much larger than the diameter of the cylinder formed by the outer rubber ring 211. At this time, the airflow flows from the support tube 201 to the outer rubber ring 211, and is accelerated after being concentrated at the outer rubber ring 211. Then the airflow will be accelerated to eject out of the device, thereby affecting a farther mine. This state is suitable for mines with a lot of dust. The device can be used in conjunction with a liquid atomizer installed inside the support tube 201 or outside the outer rubber ring 211 for dust reduction. At the same time, the device can also be used when a mine contains a small amount of harmful gas. In order to dilute the harmful gas faster, fresh air can be sprayed outside the mine.

[0027] When the device is placed in a mine for gas detection, the device can drive the second swing arm 210 and the first swing arm 208 to change their angles through the main cylinder 203 and the main motor 202 to increase the angle between the inner rubber ring 209 and the end face of the support tube 201. At the same time, the rotation of the first swing arm 208 must also be coordinated to keep the angle between the first swing arm 208 and the second swing arm 210 unchanged. In this way, the air intake range of the device can be expanded and the air intake range of the device can be made wider. After the airflow enters the transfer pipe 105, the airflow can be detected by the gas monitoring module 107 to detect the content of harmful substances in the airflow. When used in conjunction with the gas detection device on the outside of the transfer pipe 105, the device can more accurately detect the gas quality in the mine.
