Description

Technical Field

[0001] The utility model relates to the technical field of self-rescue equipment detection, in particular to a self-rescuer detection device. Background Technique

[0002] A self-rescuer is a portable breathing protection device for underground workers to prevent poisoning by harmful gases or asphyxiation due to lack of oxygen in case of fire, gas, coal dust explosion, or coal and gas outburst in the mine. It mainly consists of an oxygen cylinder and an airbag. A breathing nozzle and a nose clip are provided on the airbag. When in use, the operator holds the breathing nozzle in the mouth to breathe and clips the nose with the nose clip, so as not to breathe through the nose. During the manufacturing process of the self-rescuer, in order to ensure the airtightness of the airbag, the immersion method is used to detect its airtightness during the manufacturing process, so as to screen out unqualified airbags.

[0003] However, during the airtightness detection, since the airbag is installed on the oxygen cylinder port, during the detection, it is necessary to manually hold the oxygen cylinder and deflate it. After the airbag bulges, it is immersed in water to complete the detection process. This detection method is relatively traditional. After each airbag is detected, it is necessary to pick up the next oxygen cylinder again, inflate it, and then immerse it in water for detection, resulting in a low overall detection efficiency.

[0004] Therefore, it is necessary to provide a new self-rescuer detection device to solve the above technical problems. Content of the Utility Model

[0023] The present utility model will be further described below in conjunction with the accompanying drawings and implementation manners.

The self-rescuer detection device includes: a support table 1, and two lateral support plates 2 are fixedly installed on the top of the support table 1. A same top beam 3 is fixedly installed on one side of the two lateral support plates 2 close to each other. A water receiving pool 4 is fixedly installed on the top of the support table 1 to receive the waste water dripping from the tested airbag. A detection pool 5 is fixedly installed in the water receiving pool 4. The detection pool 5 is made of transparent plastic material to facilitate people to observe bubbles. A backrest plate 6 is fixedly installed at the bottom of the top beam 3. A bearing shaft 7 is rotatably installed thereon. Two connection frames 8 distributed at 90° are fixedly installed on the bearing shaft 7. A push screw 9 is rotatably installed in each connection frame 8. Driving motors are fixedly installed on the outer walls of the two connection frames 8 far from the bearing shaft 7. The output shafts of the two driving motors are respectively fixedly connected to one end of the two push screws 9. Push plates 10 are threadedly installed on the two push screws 9. The push plates 10 are in contact with the inner walls of the connection frames 8. Push rods 11 are fixedly installed on the two push plates 10. Installation plates 12 are fixedly installed at the ends of the two push rods 11. Jacks 13 are provided on the two installation plates 12. Clamping mechanisms are provided on the two installation plates 12. The oxygen cylinder can be inserted into the jack 13 and then fixed by the clamping mechanism.

[0025] In the above-mentioned clamping mechanism, there is a C-shaped frame 14. A bidirectional screw 15 is rotatably installed in the C-shaped frame 14. Two linkage bars 16 are threadedly installed thereon. Arc-shaped clamping plates 17 are fixedly installed on one side of the two linkage bars 16 close to each other. The arc-shaped clamping plates 17 are coaxial with the jack 13. In order to ensure that the linkage bars 16 can only move linearly, two limiting rods are fixedly installed in the C-shaped frame 14. The two limiting rods penetrate through the two linkage bars 16 and are slidably connected to the two linkage bars 16.

[0026] In this mode, in order to drain all the used water and the water dripping from the airbag, a first drain pipe 18 is fixedly installed at the bottom of the detection pool 5. The bottom end of the first drain pipe 18 penetrates through the bottom of the water receiving pool 4 and extends below the support table 1. A water valve is provided on the first drain pipe 18. Two second drain pipes 19 are fixedly installed at the bottom of the water receiving pool 4. The bottom ends of the two second drain pipes 19 both extend below the support table 1. The bottom ends of the first drain pipe 18 and the two second drain pipes 19 are fixedly installed with a same guiding water pipe 20. The guiding water pipe 20 can be connected to an external waste water pool to directly drain the waste water.

[0027] In this mode, in order to drive the bearing shaft 7 to rotate, a reduction motor 21 is fixedly installed at the bottom of the top beam 3. A gear 22 is fixedly sleeved on its output shaft. A toothed ring 23 is fixedly sleeved on the bearing shaft 7. The toothed ring 23 meshes with the gear 22.

[0028] The working principle of the self-rescuer detection device provided by the present utility model is as follows:

[0029] In this device, the guiding water pipe 20 is communicated with an external waste water tank;

[0030] When it is necessary to perform an airtightness test on the airbag, first insert an oxygen cylinder into the jack 13 on the vertically downward mounting plate 12, and then rotate the corresponding bidirectional lead screw 15. The two corresponding linkage bars 16 will move closer to each other. Finally, the oxygen cylinder is clamped by the two arc-shaped clamping plates 17. Then, open the valve of the oxygen cylinder to inflate the airbag. After it is filled, start the corresponding driving motor in the forward direction. Its output shaft drives the corresponding pushing lead screw 9 to rotate, and the pushing plate 10 drives the push rod 11 and the mounting plate 12 to move towards the detection water tank 5. When the airbag is completely submerged in the water, turn off the driving motor and start the detection. While detecting, install the next oxygen cylinder in the other empty jack 13 in the same way as above and fill the airbag with air. Then, observe the situation in the water. If bubbles appear, it means that the airtightness of the airbag does not meet the standard. If no bubbles are generated, the airbag meets the requirements;

[0031] After the above airbag detection is completed, first start the corresponding driving motor in the reverse direction to take the airbag out. Immediately start the reduction motor 21 in the forward direction. By using the meshing between the gear 22 and the toothed ring 23, the bearing shaft 7 can be driven to rotate. When it rotates 90°, turn off the reduction motor 21. At this time, the airbag that has not been detected is vertically downward. Then, start the corresponding driving motor in the forward direction to bring the airbag into the detection water tank 5. When it is completely immersed in the water, turn off the driving motor to start the airtightness detection;

[0032] During the detection process, the previously detected oxygen cylinder can be removed and the next oxygen cylinder can be installed. Then, observe the situation of the water bubbles in the detection water tank 5 again. In this way, it can be repeated. After one airbag is detected, through the rotation of the bearing shaft 7, the next airbag can be quickly detected, improving the detection efficiency;

[0033] Moreover, when replacing the airbag, the water droplets falling from the detected airbag directly fall into the water receiving tank 4 and are discharged into the guiding water pipe 20 through the second drain pipe 19 and flow into the waste water tank along the way;

[0034] Until all detections are completed, open the water valve on the first drain pipe 18 to discharge all the used water together.

[0035] Compared with the related technology, the self-rescuer detection device provided by the present utility model has the following

[0036] Beneficial effects:

[0037] The utility model provides a self-rescuer detection device. By arranging jacks 13 on both mounting plates 12, when performing airtightness detection on one airbag, the next oxygen cylinder can be installed. In this way, after one airbag is detected, by rotating the bearing shaft 7, the airbag on the next oxygen cylinder can be quickly inserted into water for detection, making full use of the time consumed in the detection process. At the same time, there is no need for manual holding of the oxygen cylinder for detection, which not only improves the detection efficiency but also reduces physical exertion, and has good performance.
