Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining equipment technology, and more specifically, to an automatic drainage structure for a mining air pump. Background Technology
[0002] During coal mining, groundwater may seep out. If not drained promptly, this water can accumulate underground, potentially flooding working faces, transport tunnels, and other areas, preventing miners from working properly and damaging electrical equipment, tracks, and other facilities, leading to safety accidents. Because scattered drainage points in coal mines often lack power or cannot be equipped with power sources for the return air at the coal face, pneumatic diaphragm pumps are frequently used for drainage. Pneumatic diaphragm pumps, also known as air-driven water pumps or air pumps, are a new type of liquid conveying machinery that uses compressed air as its power source.
[0003] However, small air pumps have insufficient head to meet drainage needs. Replacing them with high-head air pumps increases equipment investment costs, and high-head air pumps are also bulky and inconvenient to move between drainage points in coal mines. Therefore, this utility model proposes a new solution. Utility Model Content

In addition, high-head air pumps are large in size and inconvenient to move between drainage points in coal mines. Therefore, an automatic drainage structure for mine air pumps is proposed.
[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

The first tee connector is connected to a first connector and a drain pipe, and the second tee connector is connected to a second connector and an air pipe. The first connector and the second connector are connected to each other via a high-pressure hose. A mobile chassis is installed at the bottom of the blower, and a protective mechanism located outside the blower is installed on the top of the mobile chassis.

[0010] As a preferred technical solution of this utility model, mounting seats are fixedly connected to both sides of the box body, and a screw threadedly connected to the mounting seat is installed through the mounting seat. A turntable is fixedly installed at the top of the screw, and the bottom of the screw is sharp.
[0011] As a preferred technical solution of this utility model, the protective mechanism includes a plurality of first support rods fixedly installed on the top of the mobile chassis, and the tops of the plurality of first support rods are connected to an arched protective canopy. The first support rods and the protective canopy are both located on the outside of the air pump.
[0012] As a preferred technical solution of this utility model, the water inlet end of the air pump is detachably equipped with a flexible water pumping pipe, and a filter head is installed at the end of the water pump away from the air pump.
[0013] As a preferred technical solution of this utility model, the filter head includes a flat shell with multiple water inlet holes. A connecting pipe for connecting the water pumping pipe is installed on the shell. Two mutually symmetrical sleeves are fixedly connected to the outer wall of the connecting pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] In the solution of this utility model:
[0017] 1. The automatic drainage structure of this mining air pump, by setting a first tee joint, a second tee joint, a first connector and a second connector, can deliver compressed air from the air pipe to the air pump through a high-pressure hose to the drainage pipe during use, thereby pressurizing the water in the drainage pipe a second time, increasing the water flow rate, and effectively increasing the head of the air pump. This allows a small air pump to meet the drainage needs and effectively reduces equipment investment costs.
[0018] 2. This mine ventilation pump automatic drainage structure, through the setting of a movable chassis and a first tee joint, can move the ventilation pump underground by pushing the movable chassis during use, thereby facilitating the movement of multiple drainage points in the coal mine and thus facilitating drainage work.

[0032] like Figures 1-6 As shown, this embodiment proposes an automatic drainage structure for a mine air pump, including an air pump 2. The water outlet of the air pump 2 is connected to a first tee connector 3, and the air inlet of the air pump 2 is connected to a second tee connector 4. The first tee connector 3 is connected to a first connector 5 and a drain pipe 6, and the second tee connector 4 is connected to a second connector 7 and an air pipe. The first connector 5 and the second connector 7 are interconnected by a high-pressure hose 8. By setting the first tee connector 3, the second tee connector 4, the first connector 5, and the second connector 7, compressed air delivered to the air pump 2 through the air pipe can be delivered to the drain pipe 6 through the high-pressure hose 8 during use, which can repressurize the water in the drain pipe 6, increase the water flow rate, and effectively increase the head of the air pump 2. Thus, a small air pump 2 can meet the drainage needs, which can effectively reduce the equipment investment cost. A mobile chassis 1 is installed at the bottom of the air pump 2, and a protective mechanism 13 located on the outside of the air pump 2 is installed on the top of the mobile chassis 1.
[0033] like Figure 1 , Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, a mounting frame 11 is further fixedly installed on the side wall of the mobile chassis 1, and a housing 12 is installed on the top of the mounting frame 11. Multiple evenly distributed drainage grooves 14 are provided at the bottom of the housing 12. It should be noted that the mounting frame 11 and housing 12 allow for the placement of the disassembled filter head 9 and water suction pipe 10 during the movement of the mechanism, facilitating the operator to push the mobile chassis 1 to move the air pump 2 to the next drainage point. The drainage grooves 14 allow water inside the housing 12 to be drained.
[0034] like Figure 1 , Figure 2 and Figure 5As shown, in a preferred embodiment, based on the above method, further, mounting bases 15 are fixedly connected to both side walls of the housing 12. A screw 16, threadedly connected to the mounting base 15, is threaded through it. A turntable 17 is fixedly installed at the top of the screw 16, and the bottom end of the screw 16 is pointed. It should be noted that during drainage, the turntable 17 can rotate the screw 16, thereby driving the bottom end of the screw 16 into the ground, fixing the movable base 1, and preventing it from moving during pumping.
[0035] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, the protective mechanism 13 further includes a plurality of first support rods 131 fixedly installed on the top of the mobile chassis 1. The tops of the plurality of first support rods 131 are connected to an arched protective canopy 132. Both the first support rods 131 and the protective canopy 132 are located on the outside of the air pump 2. It should be noted that, during use, the protective canopy 132 can block falling rocks, thereby protecting the air pump 2. The setting of the first support rods 131 facilitates the installation of the protective canopy 132.
[0036] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a flexible water inlet pipe 10 is detachably installed at the water inlet end of the air pump 2, and a filter head 9 is installed at the end of the water inlet pipe 10 away from the air pump 2. It should be noted that, in use, the water inlet pipe 10 and the filter head 9 facilitate the use of the air pump 2 to extract accumulated water.
[0037] like Figure 1 , Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, the filter head 9 further includes a flat housing 901, a plurality of water inlet holes 903 are provided on the housing 901, a connecting pipe 902 for connecting to the water pumping pipe 10 is installed on the housing 901, two mutually symmetrical sleeves 904 are fixedly connected to the outer wall of the connecting pipe 902, a second support rod 905 is threadedly connected to the inside of the sleeve 904, and a support plate 906 is fixedly connected to the end of the second support rod 905 away from the sleeve 904. It should be noted that by setting the flat shell 901, it is easy to extract water from the crack. Compared with the traditional cylindrical or hemispherical filter head 9, it is more flexible and convenient to use. The second support rod 905 and the support plate 906 can support the shell 901 during the water extraction process, thereby preventing the end face of the shell 901 with the water inlet hole 903 from being submerged in the mud and sand in the water. When extracting water from the crack, the second support rod 905 can be removed from the sleeve 904, so that the shell 901 can be easily sent into the crack.
[0038] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, the mobile chassis 1 further includes a base plate 101, with multiple rollers 102 mounted on the bottom of the base plate 101, and a handle 103 fixedly mounted on the top of the base plate 101 on one side of the protective mechanism 13. It should be noted that the arrangement of the base plate 101, rollers 102, and handle 103 facilitates the movement of the air pump 2, thereby facilitating drainage work at multiple drainage points.
[0039] Specifically, the working principle of the automatic drainage structure of this mine air pump is as follows: During use, the compressed air delivered to the air pump 2 through the high-pressure hose 8 is delivered to the drainage pipe 6 to pressurize the water in the drainage pipe 6 and accelerate the flow rate of the water in the drainage pipe 6. During use, the second support rod 905 can be removed from the sleeve 904, so that the housing 901 can be inserted into the gap to extract the water accumulated in the gap. During use, the protective canopy 132 can block falling rocks, thereby protecting the air pump 2.
[0040] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
