Description

Technical Field

[0001] The utility model relates to the technical field of drilling and well construction, in particular to drainage equipment with an anti-leakage structure. Background Art

[0002] Exploration drilling is an engineering activity carried out to drill holes underground for the purpose of collecting underground resources, obtaining geological information or conducting geological engineering. According to the exploration results and planning requirements, the drilling location is marked on the ground and drilling equipment, including drilling platforms and wellhead facilities, is set up. After the drilling is completed, if the bottom area of ​​the well is filled with water or drilling fluid, the formation may lose or collapse, causing the wellbore to collapse or become unstable. By draining water, the bottom hole pressure can be reduced, the risk of formation loss can be reduced, and the stability of the wellbore can be maintained. In order to ensure the stability and safety of the wellbore, special drainage equipment is required to deal with the formation water, rock cuttings, mud and other materials that flow into the bottom and wellhead areas;

[0003] Common drilling construction drainage equipment is generally used in combination with a pumping component and a water purification tank. The pumping equipment is used to extract water and drilling fluid from the wellbore and bottom area and send them to the water purification tank for purification, thereby achieving the treatment and cleaning of water and drilling fluid and eliminating environmental pollution. The existing drainage equipment has been found to have the following problems in the existing technology during use:

[0004] 1. During the pumping process, the water pipe needs to be inserted into the well. There are many rocks on the inner wall of the well, which is very rough. The water pipe rubs against the inner wall of the well during the pumping process. After long-term use, the surface of the water pipe is severely worn, which eventually leads to leakage and rupture.

[0005] 2. A water purifier is installed inside the water purification pool. During the purification process, the water purifier and the pipeline are generally directly connected. The pipeline joints are not sealed, and water and drilling fluid are very easy to penetrate and leak from the joints. Utility Model Content

[0006] The purpose of this utility model is to provide a drainage device with a leak-proof structure to address the problems mentioned in the background art above, namely, that water pipes are prone to rupture due to long-term friction within the wellbore, and that the connection with the water purifier is not sealed, resulting in leakage of water and drilling fluid. To achieve the above-mentioned purpose, the utility model provides the following technical solution: A drainage device with a leak-proof structure includes a water pump, a pumping assembly mounted on one end of the water pump, a drainage pipe connected to the top of the water pump, a sealing assembly mounted on one end of the drainage pipe, and a purification assembly mounted on one end of the sealing assembly.

[0007] The water pumping assembly comprises a water pumping pipe, the outside of which is sleeved with a protective sleeve, and the surface of the protective sleeve is provided with a chain.

[0008] The sealing assembly includes a connecting tube, a silicone sleeve is sleeved inside the connecting tube, an annular spring is sleeved at one end of the silicone sleeve, a fixed pipe clamp is sleeved at the other end of the silicone sleeve, and a fastener is threadedly connected to one side of the fixed pipe clamp.

[0009] Further preferably, the purification component includes a sedimentation tank, a clean water pipe is connected to one side of the sedimentation tank, an overflow port is provided on the other side of the sedimentation tank, and a filter plate and a filter cotton core are respectively connected to the inside of the clean water pipe.

[0010] Further preferably, the water pumping pipe is made of rubber material, and the protective sleeve is made of steel plate.

[0011] Further preferably, there are a plurality of protective sleeves, and the plurality of protective sleeves are connected by chains.

[0012] Further preferably, the connecting pipe and the drain pipe are glued together, and the other end of the connecting pipe is provided with an inner and outer layer of pipes, and a certain gap is provided between the pipes.

[0013] Further preferably, the silicone sleeve and the water purification pipe are connected in a sleeve manner.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the utility model, a protective pipe is sleeved on the outside of the water pumping pipe, and each protective pipe is connected together by a chain. The protective sleeve connected by the chain can adapt to different angles and directions synchronously with the water pumping pipe, and multiple protective sleeves are connected together to avoid accidental falling off or breaking of the protective sleeves during use, thereby realizing protection of the water pumping pipe and avoiding damage caused by mutual friction between the water pumping pipe and the inner wall of the well.

[0016] In the utility model, a sealing component is added between the drainage pipe and the water purification pipe, and the annular spring is located in the gap between the inner pipe and the outer pipe. The silicone sleeve is sleeved on the outer wall of the inner pipe. In addition to relying on the friction resistance between the silicone sleeve itself and the inner pipe, the outside of the silicone sleeve can be further fixed by the annular spring. One end of the silicone sleeve is connected to the connecting pipe to increase the sealing of the pipe connection and prevent water leakage at the pipe connection during the drainage process.
