Description
A submersible sewage pump that is easy to disassemble and maintain Technical Field
[0001] This invention relates to the field of submersible sewage pumps that are easy to disassemble and maintain, and particularly to a submersible sewage pump that is easy to disassemble and maintain. Background Technology
[0002] Submersible sewage pumps are submersible sewage pumps, particularly suitable for conveying liquids containing hard solids, fibrous materials, and especially dirty, viscous, and slippery liquids. There are two types: AS and AV submersible sewage pumps. Because they operate submerged in liquid, they can be directly installed in sewage tanks without the need for a dedicated pump house, saving significant land and infrastructure costs. Since the pump and motor are coaxial, the shaft is short, and the rotating parts are lightweight, the radial load on the bearings is relatively small, resulting in a much longer lifespan than ordinary pumps. Submersible sewage pumps are gaining increasing attention and their applications are expanding. From simply conveying clean water, they can now transport various types of domestic sewage, industrial wastewater, construction site drainage, liquid feed, etc., playing a vital role in municipal engineering, industry, hospitals, construction, restaurants, water conservancy projects, and many other sectors.
[0003] In the existing technology, submersible sewage pumps are all installed in water. Due to the large amount of garbage in the water, the sewage pumps need to be picked up and maintained frequently, which is very inconvenient. The outlet connection pipe of traditional submersible sewage pumps is mostly fixed by fixing bolts. The bolts are prone to rusting after being in the water for a long time, making disassembly and assembly very difficult. Therefore, we propose a submersible sewage pump that is easy to disassemble and maintain. Summary of the Invention
[0004] The purpose of this invention is to provide a submersible sewage pump that is easy to disassemble and maintain, in order to solve the problem mentioned in the background art that submersible sewage pumps are all installed in water. Due to the large amount of garbage in the water, the sewage pumps need to be picked up and maintained frequently, which is very inconvenient. Traditional submersible sewage pump outlet connection pipes are mostly fixed by fixing bolts. The bolts are prone to rusting after being in the water for a long time, which makes disassembly and assembly very difficult.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a submersible sewage pump that is easy to disassemble and maintain, comprising a pump body and a pipe connection mechanism, wherein the pipe connection mechanism includes an outlet connection elbow, a connecting pipe is fixedly installed at one end of the outlet connection elbow near the pump body, a sealing sleeve is fixedly connected to the outlet connection elbow through a first connecting member, a second connecting member is movably connected to the first connecting member through an opening and a connecting rod, and an adapter limiting block is movably connected to the connecting rod through a slot and a strong spring.
[0006] As a preferred embodiment, the pump body has an outlet pipe on its side, a hook ring fixedly installed at the upper end of the pump body, and an inlet at the bottom of the pump body.
[0007] As a preferred embodiment, the connecting pipe is inserted into the inside of the outlet pipe, the first connecting piece is fixedly installed on the outer wall of the outlet connecting elbow near the pump body, the sealing sleeve is fixedly installed on the side of the first connecting piece, the sealing sleeve is inserted into the outer wall of the outlet pipe, and the opening penetrates the surface of the first connecting piece.
[0008] As a preferred embodiment, the second docking member is fixedly installed on the outer wall of the water outlet pipe, the docking rod is fixedly installed on the outer wall of the second docking member, the docking rod is inserted into the inside of the opening, the slot is opened inside the end of the docking rod away from the second docking member, one end of the strong spring is fixedly installed inside the slot, and the adapter limiting block is fixedly installed on the other end of the strong spring.
[0009] As a preferred embodiment, a sliding mechanism is provided on the outer side of the pump body. The sliding mechanism includes a base, and a threaded ring is fixedly installed on the upper end of the base. The threaded ring is rotatably connected to the bottom outer wall of the pump body.
[0010] As a preferred embodiment, the surface of the base has sliding holes near the four corners, and a fixing rod is slidably connected inside the sliding holes. A ground cone is fixedly installed at the bottom of the fixing rod.
[0011] The technical effects and advantages of this invention are as follows:
[0012] 1. The water outlet direction can be changed by altering the angle between the outlet connection elbow and the outlet pipe through the set pipe connection mechanism. The sealing between the outlet pipe and the outlet connection elbow is ensured by the connecting pipe and the sealing sleeve. The first and second connecting parts are connected by the connecting rod. The adapter limit block can retract within the slot to complete the opening and closing of the first and second connecting parts. This is convenient and quick, avoiding the problem of rusted and inaccessible bolts caused by the large number of bolts used in traditional sewage pumps. It also makes it easy to remove the entire sewage pump from the water for disassembly.
[0013] 2. The sliding mechanism allows the base to be connected to the pump body via a threaded ring, making assembly and disassembly convenient. The pump is fixed in the ground by inserting a ground anchor to prevent movement. The pump can be easily removed from the water for maintenance using a sliding hole and a fixing rod in conjunction with a crane, saving time. Attached Figure Description
