Description

Technical Field

[0001] The utility model relates to the technical field of water pump brackets, in particular to a coupling water pump base bracket. Background Art

[0002] There are currently two types of submersible pumps commonly used in sewage treatment plants. One type is to connect the water pump outlet and the pipeline through a flange. During maintenance, the pump pit needs to be emptied and the flange needs to be removed. The other type is to be connected through a coupling device. The water pump is lowered along the guide rail to the coupling device position and docked with the preset coupling device outlet. When the water pump needs maintenance, there is no need to empty the tank body and it can be directly inspected through the lifting chain.

[0003] The coupled water pump is easy to maintain and greatly reduces the work in confined spaces. It is used in the water supply and drainage industry, chemical industry, etc. and has a wide range of applications.

[0004] The coupling device has major drawbacks and has high requirements on the equipment design level, manufacturing accuracy and installation level. It is easy for the coupling base to be subjected to large forces due to the lever principle, concentrated force points and uneven force, resulting in excessive vibration of the water pump and coupling base, equipment wear and failure, and serious leakage of the coupling pipe mouth. This not only greatly increases the workload of equipment maintenance, but also causes energy waste, which has a great impact on production.

[0005] Therefore, in order to improve the stability of the water pump coupling device, an additional base suitable for coupling the water pump is designed. Summary of the invention

[0006] The technical problem to be solved by the utility model is that the coupling connection form between the coupling device and the submersible sewage pump leads to poor working stability of the submersible sewage pump.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is: a coupling water pump base bracket, including a submersible sewage pump foundation fixedly arranged on the bottom of the pool, the coupling device of the submersible sewage pump is connected to the top of the submersible sewage pump foundation by bolts, and a truncated cone-shaped base is fixedly connected to the bottom of the submersible sewage pump. The base is a frame structure, and the bottom surface of the base is in contact with the bottom of the pool when the submersible sewage pump is connected to the coupling device.

[0008] Preferably, a limiting structure is embedded in the bottom of the pool body, and an adapter hole for inserting the top of the limiting structure is provided at the bottom of the base.

[0009] Preferably, the base includes a coaxially arranged top ring and a bottom ring, the top ring and the bottom ring are connected by a fixing rod, the bottom ring is located below the top ring, and a connecting sleeve is arranged at an equal angle around the axis at the bottom end of the bottom ring, and the adapter hole is located in the connecting sleeve.

[0010] Preferably, the fixing rod and the connecting sleeve are arranged correspondingly, and the bottom end of the fixing rod is fixedly connected to the top end of the connecting sleeve.

[0011] Preferably, the limiting structure is a limiting bolt fixed to the bottom of the pool body.

[0012] Preferably, the submersible sewage pump foundation is pre-buried in the tank body, and the submersible sewage pump foundation is higher than the limiting structure.

[0013] Preferably, the bottom of the submersible sewage pump foundation is connected to the pool bottom via expansion bolts.

[0014] The utility model provides a coupling water pump base bracket, which pre-buries a submersible sewage pump foundation at the bottom of a pool, uses the submersible sewage pump foundation to fix and install a coupling device, installs the base at the bottom of the submersible sewage pump, and after the submersible sewage pump is lowered to the bottom of the pool through a guide rail, the submersible sewage pump is stably supported by the base, and the frame structure of the base will not interfere with the water inlet of the submersible sewage pump, thereby ensuring the stability of the operation of the submersible sewage pump.

[0020] like Figure 1-3 As shown, the utility model provides a coupling water pump base bracket, including a submersible sewage pump foundation 1 fixedly arranged on the bottom of a pool, a coupling device 2 of a submersible sewage pump 4 is connected to the top of the submersible sewage pump foundation 1 by bolts, and a truncated cone-shaped base 5 is fixedly connected to the bottom of the submersible sewage pump 4. The base 5 is a frame structure, and when the submersible sewage pump 4 is connected to the coupling device 2, the bottom surface of the base 5 contacts the bottom of the pool.

[0021] The submersible sewage pump foundation 1 is fixed to the bottom of the pool, the coupling device 2 is connected through a pipeline and fixed to the top of the submersible sewage pump foundation 1 by bolts, and a guide rail 3 is arranged in parallel on the installation pipeline of the coupling device 2, and the submersible sewage pump 4 is slidably installed on the guide rail 3. When installing the submersible sewage pump 4, the submersible sewage pump 4 is controlled to move downward along the guide rail 3 until the submersible sewage pump 4 is connected to the coupling device 2 to achieve the installation of the submersible sewage pump 4. After the submersible sewage pump 4 is docked with the coupling device 2, the base 5 at the bottom of the submersible sewage pump 4 is supported on the bottom of the pool to ensure the stability of the operation of the submersible sewage pump 4. The base 5 adopts a frame structure and will not interfere with the water inlet at the bottom of the submersible sewage pump 4.

[0022] like Figure 1-3 The bottom of the pool body is pre-buried with a limiting structure, and the bottom of the base 5 is provided with an adapter hole for the top of the limiting structure to be inserted.

[0023] By providing a limiting structure, the limiting structure cooperates with the base 5. After the submersible sewage pump 4 and the coupling device 2 are installed, the base 5 is limited in the horizontal direction by the limiting structure to improve the stability of the submersible sewage pump 4.

[0024] like Figure 1-3 The base 5 comprises a coaxially arranged top ring 51 and a bottom ring 52, the top ring 51 and the bottom ring 52 are connected by a fixing rod, the bottom ring 52 is located below the top ring 51, and a connecting sleeve 53 is arranged at an equal angle around the axis at the bottom end of the bottom ring 52, and the adapting hole is located in the connecting sleeve 53.

[0025] During the descent of the submersible sewage pump 4, the top end of the limiting structure enters the connecting sleeve 53. Since there are multiple connecting sleeves 53, after the connecting sleeve 53 cooperates with the limiting structure, effective limiting of the base 5 can be achieved. The top ring 51 and the bottom ring 52 are connected by a fixing rod, so that the base 5 can provide stable support for the submersible sewage pump 4.

[0026] like Figure 2 and Figure 3 The fixing rod is arranged corresponding to the connecting sleeve 53, and the bottom end of the fixing rod is fixedly connected to the top end of the connecting sleeve 53. The connecting sleeve 53 is welded to the bottom ring 52, and the connecting sleeve 53 is connected by the fixing rod to ensure the stability of the installation of the connecting sleeve 53, so that the connecting sleeve 53 can be accurately aligned with the limiting structure during the descending process of the submersible sewage pump 4.

[0027] As a preferred embodiment of the utility model, the limiting structure is a limiting bolt 6 fixed to the bottom of the pool body. The limiting bolt 6 is an expansion bolt, which is directly installed on the bottom of the pool with the top extending out. When the submersible sewage pump 4 descends, the top of the limiting bolt 6 cooperates with the connecting sleeve 53.

[0028] like Figure 1As shown, in order to achieve stable installation of the coupling device 2, the water inflow after the installation of the submersible sewage pump 4 will not be weakened. The submersible sewage pump foundation 1 is pre-buried in the tank body, and the submersible sewage pump foundation 1 is higher than the limiting structure.

[0029] like Figure 1 As shown, in order to improve the installation stability of the submersible sewage pump foundation 1, the bottom of the submersible sewage pump foundation 1 is connected to the pool bottom through expansion bolts.
