Description

Technical Field

[0001] The utility model relates to the technical field of drainage pumps, in particular to a coal mine drainage pump with an anti-blocking structure. Background Art

[0002] In the coal mine production process, groundwater is inevitable, but if the groundwater cannot be discharged in time, it will cause water accumulation in the mine, which will pose a serious threat to the lives and safety of the miners. Therefore, the existence of coal mine drainage pumps is directly related to the safety of the miners. Through the drainage pumps, miners can discharge groundwater from the mine in time to ensure safety in the production process.

[0003] At present, when the existing coal mine drainage pump is in use, the accumulated water in the coal mine will enter the pump body through the water inlet of the pump body. Since there are a large amount of sand, gravel and soil blocks in the accumulated water inside the mine, when the drainage pump is directly placed in the accumulated water for drainage, the sand, gravel and soil blocks inside the accumulated water can easily enter the interior of the drainage pump, causing the drainage pump to be blocked and easily causing damage to the drainage pump. For this reason, we propose a coal mine drainage pump with an anti-blocking structure to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a coal mine drainage pump with an anti-blocking structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 A coal mine drainage pump with an anti-blocking structure includes a pump body 1, a water inlet 3 is provided on the right side of the bottom end of the pump body 1, a water outlet 4 is provided on the left side of the bottom end of the pump body 1, a filter screen 5 is inserted inside the water inlet 3, and a groove is provided on the inner wall of the water inlet 3 below the filter screen 5, the inner wall of the groove is connected with a collecting pipe 6, and a sealing plug 7 is inserted at the bottom end of the collecting pipe 6.

[0023] Further, refer to Figure 3 It can be seen that the filter screen 5 is set to an inclined structure, and a disassembly mechanism is provided on the right side of the filter screen 5. The filter screen 5 set to an inclined structure can reduce the debris attached to the filter screen 5, thereby achieving the purpose of preliminary anti-blocking.

[0024] Further, refer to Figure 3 It can be seen that the disassembly mechanism includes connecting rods 8, and there are four groups of connecting rods 8. One end of the four groups of connecting rods 8 is connected to the side of the filter screen 5, and the other end of the four groups of connecting rods 8 is connected to the mounting block 9. Four groups of slots that are compatible with the mounting block 9 are provided inside the water inlet 3. The inside of the mounting block 9 is connected to the water inlet 3 by bolts. Through the mutual cooperation of the four groups of connecting rods 8 and the mounting block 9, it is convenient for the staff to replace and maintain the filter screen 5 that has reached the end of its service life.

[0025] Further, refer to Figure 3 and Figure 4It can be seen that the inside of the water inlet 3 is connected to the rotating shaft 10 through a bearing, and the outside of the rotating shaft 10 is equidistantly connected to a rectangular plate 11, a cam 12 is sleeved at the center position of the rotating shaft 10, and a cross bar 13 is provided on the side of the cam 12, a sleeve 14 is sleeved on the outside of the cross bar 13, and the two ends of the sleeve 14 are connected to the inner wall of the water inlet 3 through a support rod 16, a connecting disk 17 is sleeved on the outside of the cross bar 13, and the side of the connecting disk 17 is connected to the sleeve 14 through a connecting spring 18. When water flows into the inside of the water inlet 3, it will push the rectangular plate 11 to rotate under force, so that the rotating shaft 10 rotates at the same time, so that the cam 12 intermittently collides with the cross bar 13, so as to achieve knocking on the filter screen 5, thereby further improving the anti-blocking effect of the filter screen 5.

[0026] Further, refer to Figure 3 It can be seen that the two ends of the cross bar 13 are symmetrically connected with connecting blocks 15, and the connecting blocks 15 are set to a spherical structure. The connecting blocks 15 are set to rubber material. The connecting blocks 15 set by the spherical structure can ensure the normal rotation of the cam 12, and can effectively prevent the cam 12 from directly colliding with the cross bar 13, and the cross bar 13 from colliding with the filter screen 5, so as to achieve protection of the cam 12 and the filter screen 5.

[0027] Further, refer to Figure 3 It can be seen that a pull ring is connected to the lower side of the sealing plug 7, and anti-slip particles are evenly distributed on the outer surface of the pull ring. The outer wall of the sealing plug 7 and the inner wall of the collecting tube 6 are tightly fitted. Through the mutual cooperation between the pull ring and the anti-slip particles, the convenience of the staff in pulling the sealing plug 7 can be effectively improved.

[0028] Further, refer to Figure 1 and Figure 2 It can be seen that the bottom end of the pump body 1 is symmetrically connected with a threaded sleeve 2, and the water inlet 3 and the water outlet 4 are close to each other on one side respectively provided with an external thread compatible with the threaded sleeve 2. Through the threaded cooperation between the water inlet 3, the water outlet 4 and the threaded sleeve 2, the water inlet 3 and the water outlet 4 can be removed from the bottom end of the device during transportation to reduce the footprint of the device, which can effectively facilitate the storage of the device and can replace the damaged water inlet 3 and water outlet 4 in time.

[0029] Working principle: When the utility model is in use, the staff can first connect the drainage pipe to the water inlet 3 and the water outlet 4 through the flange, and then start the pump body 1, so that the accumulated water inside the mine can be discharged smoothly. When the accumulated water enters the inside of the water inlet 3, the filter screen 5 provided inside the water inlet 3 can block the large particles of debris in the accumulated water, and the blocked debris can fall into the collection pipe 6 under gravity for collection. When the accumulated water enters the inside of the water inlet 3, it will push the rectangular plate 11 to flip, thereby driving the continuous rotation of the rotating shaft 10. At this time, the cam 1 set on the outer side of the rotating shaft 10 2 can rotate simultaneously, and the raised part of the cam 12 intermittently hits the connecting block 15, so that the cross bar 13 is forced to move laterally and hit the filter screen 5 to knock off the debris attached to the filter screen 5. After using for a period of time, when the collection pipe 6 is about to be full, the staff can suspend the operation of the pump body 1 and then pull out the sealing plug 7 from the opening of the collection pipe 6 to dump the debris inside the sealing plug 7. After dumping is completed, the staff can insert the sealing plug 7 into the collection pipe 6 again and then start the pump body 1 to continue the drainage operation. The above is the entire working principle of the utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated on.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
