Description

Technical Field

[0001] This utility model relates to the field of air radon monitoring technology, and in particular to an air radon monitoring device under special conditions. Background Technology

[0002] In the mining industry, it is necessary to monitor radon in the air inside mines. However, the environment inside mines is complex, with issues such as sidewall collapses, toxic gases, high levels of radioactive radiation, and water accumulation or flow. Manually installing the air intake of radon monitoring instruments inside mines poses safety risks.

[0003] Traditional radon monitoring devices for special environments rely on the radioactive properties of radon and its decay products. By detecting the alpha particles released during decay or collecting short-lived progeny, such as activated carbon adsorption or filter membrane collection, the radioactive signal is converted into a measurable signal such as electrical pulse or ray intensity, which is then used to calculate the radon concentration in the air. At the same time, protective design, ventilation control, and anti-interference measures are combined to adapt to special environments.

[0004] Currently used traditional radon monitoring devices for special environments mostly require manual carrying to the designated entrance. These devices are generally large, and when workers need to walk long distances, they have to carry them for extended periods, which is inconvenient and increases the fatigue of workers. Therefore, a new radon monitoring device for special environments is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of an air radon monitoring device for special environments, comprising a main body 1, a circular ring plate 101 fixedly connected to the rear wall of the main body 1, and a handle 104 rotatably connected to the outer wall of the main body 1, which allows the monitor to be mounted on a placement rack 303, facilitating the movement of the device. In complex terrain, the device can be lifted using the handle 104 for easy carrying. An adjustment mechanism 2 is provided on the side of the circular ring plate 101 away from the main body 1. The adjustment mechanism 2 includes two electrically controlled telescopic rods 201, both fixedly connected to the side of the circular ring plate 101 away from the main body 1. The monitor is mounted on the placement rack 303 and then stored on a take-up reel 305. The rubber hose is connected to the air pipe connector 108. When the electric telescopic rod 201 is activated, the main body 1 moves into the hole on the ground by the thrust applied by the electric telescopic rod 201. Each output end of the electric telescopic rod 201 is fixedly connected to a sliding block 202. Each end of the electric telescopic rod 201 near the annular plate 101 is rotatably connected to an L-shaped wheel set 204. A fixing mechanism 3 is provided inside the sliding block 202. The fixing mechanism 3 includes two fixing rods 301. The fixing rods 301 are respectively set inside the two sliding blocks 202. Each fixing rod 301 is fixedly connected to a connecting frame 302 at the top. The end of the connecting frame 302 away from the fixing rod 301 is fixedly connected to a placement frame 303.

[0035] Reference Figures 4-6 A limiting insertion block 102 is fixedly connected to the side of the annular plate 101 away from the main body 1. A limiting insertion strip 106 is provided inside the limiting insertion block 102. After the main body 1 is supported by the L-shaped wheel set 204, the limiting insertion strip 106 is inserted into the limiting insertion block 102 to limit the L-shaped wheel set 204 after it is supported. A camera component 105 is fixedly connected to the outer wall of the main body 1. The camera component 105 can transmit the environment inside the cave to the external display device to observe the situation inside the cave or the location of the main body 1 in real time. An air intake fan 103 is fixedly connected inside the main body 1. When the air intake fan 103 is turned on, the gas inside the cave is drawn into the main body 1, which facilitates the full intake of the gas inside the cave by the air intake port on the monitor.

[0036] Reference Figures 1-6A conical cylinder 107 is fixedly connected to the side of the annular plate 101 away from the main body 1. The conical cylinder 107 communicates with the interior of the main body 1. An air pipe connector 108 is snapped into the end of the conical cylinder 107 away from the annular plate 101. A rubber tube is connected to the outside of the air pipe connector 108. The adjusting mechanism 2 also includes two tightening devices 203. The tightening devices 203 are respectively threaded to the two sliding block 202 on the opposite sides. The tightening devices 203 abut against the outer wall of the fixed insertion rod 301. The fixing mechanism 3 installed on the top of the electric telescopic rod 201 is removed. Two fixing holes are drilled in the ground in advance, and then the two fixed insertion rods 301 are respectively inserted into the two sliding block 202, so that the fixed insertion rods 301 are inserted into the two holes drilled in the ground. Inside the fixed hole, the fixing rod 301 is pressed and fixed inside the sliding hole block 202 by the tightening device 203, so that the rear end of the device can be fixed to the ground outside the hole. The side of the electric telescopic rod 201 away from the annular plate 101 is fixedly connected to the insertion strip 205. The insertion strip 205 has a positioning hole at its center. The sliding hole blocks 202 are fixedly connected to the bolt bracket 206, and the side of the bolt bracket 206 near the insertion strip 205 is fixedly connected to the positioning bolt. When the bolt bracket 206 abuts against the insertion strip 205, the positioning bolt will pass through the positioning hole and be fixed by the nut. The limiting insertion strip 106 is removed from the limiting insertion block 102. The L-shaped wheel set 204 is on the two electric telescopic rods 202. The device rotates between the two L-shaped wheel sets 204, allowing them to retract between the two electrically controlled telescopic rods 201. This causes the end of the L-shaped wheel set 204 away from the electrically controlled telescopic rod 201 to contact the ground. In this way, when moving the device, pulling the handle 104 causes the device to roll on the ground via the rollers at the end of the L-shaped wheel set 204 away from the electrically controlled telescopic rod 201. The fixing mechanism 3 also includes two rotating drum frames 304, both fixedly connected to the bottom of the placement frame 303 near the connecting frame 302. A winding wheel 305 is rotatably connected between the two rotating drum frames 304, with a rubber tube wound on the winding wheel 305. Multiple evenly distributed ventilation openings are located at the bottom of the placement frame 303. The device has two bolts at the top of each of the two electrically controlled telescopic rods 201, and two through holes on the outer wall of each of the two fixed rods 301. After the through holes are fitted onto the bolts, the nuts are tightened onto the bolts. After the electrically controlled telescopic rod 201 retracts, the fixed rod 301 can be pulled out of the sliding block 202. Through the two sets of through holes on the fixed rod 301, the fixed rod 301 is fitted onto the two sets of bolts at the top of the electrically controlled telescopic rod 201. Then, the nuts are tightened onto the bolts at the top of the electrically controlled telescopic rod 201, thereby fixing the fixing mechanism 3 to the top of the electrically controlled telescopic rod 201. The device can be folded and stored, and the fixed rod 301 is fastened to the top of the electrically controlled telescopic rod 201. The bottom of the fixed rod 301 is tapered.

[0037] Working principle: After the electrically controlled telescopic rod 201 retracts, the fixing rod 301 can be pulled out of the sliding hole block 202. Through the two sets of through holes on the fixing rod 301, the fixing rod 301 is fitted onto the two sets of bolts at the top of the electrically controlled telescopic rod 201. Then, the nut is screwed onto the bolts at the top of the electrically controlled telescopic rod 201, thereby fixing the fixing mechanism 3 to the top of the electrically controlled telescopic rod 201. The device can then be folded and stored. At the same time, the limiting insert 106 is removed from the limiting insert block 102, and the L-shaped wheel set 204 rotates between the two electrically controlled telescopic rods 201. The two L-shaped wheel sets 204 can be retracted between the two electrically controlled telescopic rods 201, so that the moving wheel at the end of the L-shaped wheel set 204 away from the electrically controlled telescopic rod 201 contacts the ground. In this way, when carrying the device, the device can be rolled on the ground by pulling the handle 104 through the roller at the end of the L-shaped wheel set 204 away from the electrically controlled telescopic rod 201. At the same time, the monitor can be installed on the placement frame 303, which facilitates the movement of the device. In complex terrain, the device can be lifted by the handle 104, making it easy to carry.

[0038] After the main body 1 is supported by the L-shaped wheel assembly 204, the limiting insert 106 is inserted into the limiting insert block 102 to limit the L-shaped wheel assembly 204 after it is supported. After the device is placed on the ground, the fixing mechanism 3 installed on the top of the electric telescopic rod 201 is removed. Two fixing holes are drilled in the ground in advance, and two fixing rods 301 are inserted into the two sliding hole blocks 202 respectively, so that the fixing rods 301 are inserted into the two fixing holes drilled in the ground. Then, the fixing rods 301 are pressed and fixed in the position inside the sliding hole block 202 by the tightening device 203. In this way, the rear end of the device can be fixed to the ground outside the cave, so that the main body 1 can enter the cave for air monitoring. After the device is assembled, the monitor is installed on the placement frame 303. Connect the rubber hose stored on the take-up reel 305 to the air hose connector 108, activate the electric telescopic rod 201, and use the thrust applied by the electric telescopic rod 201 to move the main body 1 from the ground into the cave. The camera component 105 can transmit the environment inside the cave to an external display device to observe the situation inside the cave or the location of the main body 1 in real time. After the main body 1 enters the designated position inside the cave, remove all the rubber hoses from the take-up reel 305, connect the other end of the rubber hoses to the monitor installed on the placement frame 303, and activate the air intake fan 103 to draw the gas inside the cave into the main body 1, so that the air intake port on the monitor can fully draw in the gas inside the cave. At the same time, the take-up reel 305 set inside the two rotating drum frames 304 facilitates the storage of the rubber hoses.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
