Description

Technical Field

[0001] The utility model relates to combined equipment for local desilting and diversion of a mine ditch. Background Art

[0002] In mining production, mine ditches play an important role. They are responsible for discharging wastewater generated inside the mine to ensure safe and continuous production. However, many mine ditch systems currently have problems such as unreasonable design, serious aging, and improper maintenance, which lead to safety hazards such as poor water flow, easy water accumulation, and easy flooding. At the same time, with the increase in mining depth and the expansion of production scale, these ditches also bear the drainage function and are difficult to stop using. When dredging, they can only be flushed with high-pressure water guns, but high-pressure water guns can only flush the debris accumulated in the upstream ditch to the downstream ditch, making it difficult to thoroughly clean and repair the mine ditch. The existing technology lacks equipment and technology that can provide relatively dry construction conditions for local ditches that need to be repaired and dredged without stopping the mine ditch as a whole. Summary of the invention

[0003] The technical problem to be solved by the utility model is how to fill the above-mentioned gap in the prior art and provide a combined device for local desilting and diversion of a mine ditch.

[0004] In order to solve the above technical problems, the combined equipment for local desilting and diversion of mine ditches includes two inflatable bags and two submersible pumps, each of which is in the shape of a rounded square block and is respectively connected to an air valve. The submersible pump is a centrifugal submersible pump, which includes a tubular base, a pump body and a drive motor. The tubular base is sleeved on the water inlet at the center of the pump body, and the side wall of the tubular base is densely covered with a plurality of strip-shaped through holes. The drive motor is fixed above the pump body, and its output shaft is connected to the impeller in the pump body. Two outlet pipes are symmetrically arranged on the pump body of each submersible pump, and the two outlet pipes are respectively connected to the first interface and the second interface of a three-way pipe through a pipeline, and the third interfaces of the three-way pipes of the two submersible pumps are respectively connected to a long drainage hose and a short drainage hose. The air valve can be a new type of one-way air stop valve disclosed in Chinese patent document CN202484374U, or other commonly used air valves.

[0005] When a section of a mine ditch needs to be repaired or desilted, take out two inflatable bags, place them upstream and downstream of the mine ditch to be repaired or desilted, and inflate them respectively to expand the two inflatable bags, get stuck in and block the mine ditch, then take out a submersible pump with a long drainage hose, place it in the mine ditch upstream of the mine ditch to be repaired or desilted, place the other end of the long drainage hose in the mine ditch downstream of the mine ditch to be repaired or desilted, and fix it on the matching ditch cover, then start the submersible pump with the long drainage hose, such as Figure 3As shown, the flowing water in the mining ditch no longer passes through the mining ditch to be repaired or desilted between the two inflatable bags, but flows downward through the submersible pump with a long drainage hose, thereby realizing diversion.

[0006] The centrifugal submersible pump of this patent is provided with two water outlet pipes arranged in a tangential direction. Compared with the ordinary centrifugal submersible pump with only one water outlet pipe, it has a symmetrical structure and stable operation.

[0007] Then take a submersible pump with a short drainage hose, place it in the mine ditch between the two inflatable bags, place the other end of the short drainage hose in the mine ditch downstream of the mine ditch to be repaired or desilted, and fix it on the equipped ditch cover 10, as shown in FIG. Figure 4 As shown, the submersible pump with a short drainage hose is started until all the accumulated water in the mine ditch between the two inflatable bags is drained, and then the submersible pump with a short drainage hose is stopped, and then the debris or silt in the mine ditch between the two inflatable bags can be cleaned and maintained. With this design, the entire mine ditch can be cleaned and maintained in sections without stopping use.

[0008] As an optimization, a flexible fixed foot pad is fixed on the left and right sides of each inflatable bag. The upper edge of the flexible fixed foot pad is fixed on the inflatable bag, and the lower edge extends outward. The front and rear edges of the flexible fixed foot pad are flush with the front and rear sides of the inflatable bag, and can be stuck on the side wall of the mine ditch. Before inflation, first step the drooping part of the flexible fixed foot pad to the bottom of the mine ditch to make it fully fit with the mine ditch, and then inflate. This design can better block the water flow, and after inflation, the inflatable bag will not float up due to the buoyancy of the water.

[0009] The combined equipment for local desilting and diverting of mine ditches has a simple structure and is easy to use, and is suitable for local desilting and diverting of mine ditches. BRIEF DESCRIPTION OF THE DRAWINGS
