Description

Technical Field

[0001] The utility model relates to the technical field of motor pumps, in particular to a motor pump housing that is convenient for disassembly and assembly. Background Art

[0002] A motor pump is a pump driven by electricity, mainly composed of a pump body, a lift pipe, a pump base, a submersible motor (including a cable), a starting protection device, etc. The motor pump housing refers to the submersible pump motor housing, which is usually composed of a steel ring made of Q235 material, adopts a plastic deformation shell structure, and forms an arched structure. The design of this housing takes into account various factors to ensure that it can adapt to different environmental factors. The manufacturing material of the housing is not only lightweight but also has high strength, and can effectively cope with the challenges of various working environments. In addition, the material and design of the motor pump housing also consider cost-effectiveness and durability to ensure the stability and reliability of long-term use. The operating conditions of the motor pump include that the temperature should not be higher than 20°C and the pH value of the liquid acidity and alkalinity is 6.5 - 8.5. The motor pump can be widely used in different fields. Except in flammable, explosive or corrosive gas occasions, it can also be used in supporting equipment such as machine tools, pumps, blowers, compressors, etc. A junction box structure is usually provided above the motor pump housing for connecting lines to improve the connection effect of the lines. However, for the common motor pump housing on the market, when it needs to be repaired due to damage, it needs to be disassembled first, and after the repair is completed, it needs to be reassembled and fixed again. However, the overall disassembly of the motor pump housing is relatively laborious and not convenient enough. After the lines are connected, in case of rain, rainwater easily enters through the hole position of the lines, resulting in a short circuit of the lines and affecting the use. Summary of the Utility Model

[0003] The embodiment of the present disclosure relates to a motor pump housing that is convenient for disassembly and assembly. When connecting lines, it can control the lines to be inserted into the inside of the plugging structure and the retaining ring structure at the same time. After the lines are connected, the cover plate can be fixed to the top of the junction box structure through bolts. At the same time, the retaining ring structure is continuously stressed by elasticity and fits with the outside of the lines to seal the gap, so that when the housing body encounters rain, rainwater will not enter the inside of the junction box structure.

[0004] In the first aspect of the present disclosure, a motor pump housing that is convenient for disassembly and assembly is provided, specifically including: a housing body; heat dissipation fins are provided on the outside of the housing body, and both sides of the bottom of the housing body are slidably connected to a moving head assembly through a connecting block assembly and a sliding groove. The bottom of the moving head assembly is fixedly welded to a bottom plate assembly. A sliding groove is formed inside the bottom plate assembly, and uniformly arranged rotating assemblies are respectively installed on both bottom sides of the sliding groove. The rotating assemblies are freely rotatable structures; a junction box structure; the junction box structure is fixedly installed at the top of the housing body, and a sealing structure made of flexible rubber is installed on the side of the junction box structure through a mounting hole. Two retaining ring structures are fixed inside the sealing structure, and the rubber retaining ring structures are funnel-shaped structures.

[0005] In at least some embodiments, a connecting block assembly is respectively fixed on both sides of the bottom of the housing body. The inner end of the connecting block assembly is an inclined structure, and two sliding grooves are penetrated inside each connecting block assembly; a T-shaped moving head assembly is inserted into each sliding groove and freely slides inside the sliding groove. The inside of the sliding groove is an arc structure, and the cross-section of the sliding groove is a T-shaped structure; a pulling member is fixed on the outside of the bottom plate assembly, and both ends of the pulling member are L-shaped structures. An L-shaped fixing plate assembly is inserted into each sliding groove. The bottom of the fixing plate assembly is in sliding contact with the top of the rotating assembly, and a bolt is inserted into the fixing plate assembly and simultaneously inserted into the sliding groove.

[0006] In at least some embodiments, heat dissipation grooves are respectively formed on both sides of the junction box structure, and a baffle structure is fixed on the side of the junction box structure. The inner side of the baffle structure is an inclined structure, and the baffle structure is located above the outside of the heat dissipation grooves; a wiring column is fixed at the bottom end inside the junction box structure, and the wiring column is connected to a circuit. Connecting members are provided on both sides inside the junction box structure, and a cover plate is installed on the connecting members through bolts; two mounting holes are penetrated on the side of the junction box structure, and the circuit is simultaneously inserted into the sealing structure and the retaining ring structure.

[0007] The utility model provides a motor pump housing that is convenient for disassembly and assembly, and has the following beneficial effects:

[0008] When the housing body is integrally fixed to form a motor pump, bolts can be controlled to be inserted into the fixing plate assembly and the sliding groove at the same time. After the bolts are tightened, the fixing plate assembly and the bottom plate assembly are pressed and fixed, and the housing body is firmly fixed. When the motor pump is damaged and needs to be disassembled and repaired, the fixed bolts can be loosened, and the pulling piece can be directly pulled to displace. The pulling piece drives the bottom plate assembly to displace laterally together. The moving head assembly slides in the chute at the same time, and the fixing plate assembly slides in the sliding groove. The bottom plate assembly slides out of the way, so that the bottom plate assembly is no longer limited and fixed, and the motor pump can be disassembled conveniently for maintenance. When it is necessary to reassemble and fix, the housing body can be reset, the bottom plate assembly can be controlled to move inward, and the bolts can be tightened again to firmly fix the housing body, improving the assembly efficiency.

[0009] When it is necessary to connect the circuit, the circuit can be controlled to be inserted into the plugging structure and the retaining ring structure at the same time. After the circuit is connected, the cover plate can be fixed to the top of the junction box structure by bolts. At the same time, the retaining ring structure is continuously stressed by elasticity and fits with the outside of the circuit to seal the gap, so that when the housing body encounters rainwater, the rainwater will not enter the inside of the junction box structure.
