Description

Technical Field

[0001] This utility model belongs to the technical field of submersible pumps, specifically relating to a device for preventing the guide rod of a submersible pump from falling off. Background Technology

[0002] A submersible pump is a water lifting device, mainly used in deep wells, pools, and other similar places. When in use, the entire unit is completely submerged in water, which can lift water from underground pits to the surface. It is an important piece of equipment in domestic water supply, industrial cooling, mining construction, and other work.

[0003] When installing a submersible pump, a guide rod is usually installed above the water storage tank beforehand. The guide rod is connected to the quick-connect interface of the submersible pump, which can stably deliver the submersible pump into the water storage tank. The guide rod is usually fixed to the inner wall of the water tank with bolts. Under long-term use, due to factors such as vibration, the bolts are prone to loosening. Current technology usually does not have a structure to prevent the guide rod from falling off. After the bolts loosen, the guide rod is easy to fall into the water tank, which is inconvenient for the staff to retrieve. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a device to prevent the guide rod of a submersible pump from falling off. When the bolts of the guide rod bracket become loose, the metal mesh can limit the guide rod, preventing it from falling into the water pool and requiring subsequent retrieval, and making it easier for staff to maintain.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] Submersible pump guide rod anti-detachment device, including

[0007] The mounting block has a through groove on its left rear side and a sliding groove on its left side. The inner wall of the sliding groove on its rear side has a displacement groove that connects to the through groove.

[0008] A metal mesh is fixedly installed on the front side of the mounting block. One end of the metal mesh passes through a through groove and is fixedly connected to a metal strip. One end of the metal strip is fixedly connected to an assembly component.

[0009] A locking assembly is slidably fitted inside a slide groove and is used to lock the metal mesh.

[0010] As a preferred technical solution, the assembly component is a metal buckle or a hanging sleeve.

[0011] As a preferred technical solution, the locking assembly includes a slider, which is slidably assembled inside a slide groove. A spring is fixedly installed on the front side of the slider, and one end of the spring is fixedly connected to the inner wall of the slide groove. A locking block is fixedly installed on the rear side of the slider, and a plurality of locking teeth are arranged on the rear side of the locking block. A moving block is fixedly installed on the left side of the slider.

[0012] As a preferred technical solution, a bevel is provided on the rear right side of several of the locking teeth.

[0013] The beneficial effects of this utility model are:

[0014] After the guide rod and submersible pump are installed, the metal mesh is then assembled. This effectively avoids increasing the diameter of the guide rod, which would affect the connection between the guide rod and the quick-connect port of the submersible pump. After the metal mesh is installed, it fixes the guide rod in place. If the guide rod becomes loose, the metal mesh limits its movement to prevent it from falling into the pool. Subsequently, the guide rod needs to be retrieved by staff for maintenance. Attached Figure Description

[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-5 As shown, the submersible pump guide rod anti-detachment device of this utility model includes...

[0024] Mounting block 1, a through groove 11 is provided on the rear left side of mounting block 1, a sliding groove 12 is provided on the left side of mounting block 1, and a displacement groove 13 connected to the through groove 11 is provided on the inner wall of the rear side of sliding groove 12.

[0025] Metal mesh 2 is fixedly installed on the front side of mounting block 1. One end of metal mesh 2 passes through through groove 11 and is fixedly connected to metal strip 21. One end of metal strip 21 is fixedly connected to assembly component 22. Specifically, assembly component 22 is metal buckle or hanging sleeve.

[0026] In the initial state, after the guide rod is installed, the staff aligns the quick-connect interface of the submersible pump with the guide rod and inserts it. The guide rod guides the submersible pump to the designated position. In the initial state, the metal mesh 2 does not pass through the through groove 11. The surface of the metal mesh 2 has several holes. The metal material has good corrosion resistance and high strength. The staff uses the metal mesh to hold the guide rod and controls the end connected to the equipment component 22 to pass through the through groove 11. As the staff pulls the metal mesh 2, the metal mesh 2 forms a pocket shape to hold the guide rod. Finally, the locking component 3 is used to lock the position of the metal mesh 2. The staff has installed connection points on the top of the pool in advance for connecting with the hanging sleeve or metal buckle, so that the hanging sleeve or metal buckle can be connected to the connection point. In this way, without affecting the function of the guide rod, when the bolts connecting the guide rod to the pool loosen, the metal mesh 2 fixes the guide rod and prevents the guide rod and the bracket from falling into the pool, making it easy for the staff to reinforce it again without having to retrieve it.

[0027] Locking component 3 is slidably assembled inside the slide groove 12 and is used to lock the metal mesh 2. Specifically, locking component 3 includes slider 31, which is slidably assembled inside the slide groove 12. A spring 32 is fixedly installed on the front side of slider 31, and one end of spring 32 is fixedly connected to the inner wall of slide groove 12. A locking block 33 is fixedly installed on the rear side of slider 31. Several locking teeth 34 are arranged on the rear side of locking block 33. A moving block 35 is fixedly installed on the left side of slider 31. An inclined surface 341 is opened on the rear right side of several locking teeth 34.

[0028] In use, after the assembly component 22 is passed through the through slot, when the assembly component contacts the inclined surface formed by the locking teeth 24, a squeezing force is generated at the inclined surface, pushing the locking block 33 to move. The locking block 33 drives the slider 31 to move, and the slider 31 pushes the spring 32 to tighten. As the operator pulls, when the metal mesh 2 is aligned with the locking teeth 24, under the action of the spring 32, the locking teeth 24 will insert into the mesh holes of the inverted metal mesh 2, limiting the position of the metal mesh 2. Due to the inclined surface 3... The 41 setting allows the operator to continuously pull the metal mesh 2 until the guide rod is tightened. When the pulling of the metal mesh 2 stops, several locking teeth 24 will insert into the mesh holes of the metal mesh 2 to lock the metal mesh 2. No additional operation is required, making it simple and convenient to use. When releasing the lock and removing the metal mesh 2, the operator can manually move the moving block 35. The moving block 35 will cause the locking block 33 to move and cancel the connection with the mesh holes of the metal mesh 2. In this way, the operator can pull out the metal mesh 2 and cancel the connection.

[0029] The device is used as follows:

[0030] In use, after the guide rod is installed, the worker passes the metal mesh 2 through the through groove 11. Under the action of the spring 32, several locking teeth 34 can be pushed in real time to align with the mesh of the metal mesh 2. Due to the opening of the inclined surface 341, the worker can continuously pull the metal mesh 2 to lock the guide rod until it is locked. Then, the assembly component 22 is used to connect with the connection point pre-set on the pool side. In this way, even if the bolt of the guide rod comes loose, the guide rod will not fall directly into the pool water due to the setting of the metal mesh 2. When removing the net bag, the connection between the assembly component 22 and the connection point on the pool side is canceled, and then the moving block 35 is moved to drive the slider 31 to move, canceling the connection with the mesh of the metal mesh 2, and the metal mesh 2 can be removed. The operation is simple and convenient.

[0031] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
