Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to a submerged water pump suction device. Background Technology

[0002] In the field of water pump technology, existing submersible water pump suction devices still face unresolved problems such as silt trapping, water flow disturbance, and cable wear under complex operating conditions. In environments with abundant silt, the pump easily sinks due to its own weight in soft silt, leading to inlet blockage and maintenance difficulties. When the side water flow is disturbed, conventional designs such as counterweights or rigid supports cannot effectively convert the kinetic energy of the water flow, causing the pump body to deviate significantly in high-speed water flow, affecting normal operation. Existing technologies have attempted to address these problems, such as by adding external suspension structures to increase buoyancy or by adding guide plates to disperse the water flow, but these have failed to achieve functional integration. The designed components are relatively scattered, often sacrificing the compactness of the equipment. Moreover, during use, when the cable passes through cable protection pipes, the cable bends are prone to wear against the edges of the pipes, or the cable is completely exposed underwater, causing contact wear between the cable and the silt in the water.

[0003] To overcome the above-mentioned shortcomings, the inventors invented a submerged water pump suction device. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a submersible water pump suction device that can achieve continuous submersion by reducing its own weight, avoid inlet blockage and maintenance difficulties, and effectively convert water kinetic energy when the side water flow is disturbed, ensuring that the pump body will not deviate significantly in high-speed water flow and ensuring the normal operation of the pump body. In addition, the device and components of this application are highly compact, and the cable is not easily worn when bent at the edge of the protective tube during use, and the cable will not come into contact with mud and sand in the water and wear down.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A submerged water pump suction device includes a water pump suction device, which includes a housing and a water outlet pipe. A hollow stabilizing seat is provided on the outer sleeve of the housing. A positioning device is provided on the inner side of the hollow stabilizing seat. A guide pipe is provided on the side wall of the hollow stabilizing seat. The guide pipe and the water outlet pipe are arranged on the same central axis.

[0007] As a further implementation, a cable through hole is provided on the bottom side wall of the guide tube, and the cable through hole is connected to the bottom of the cable conduit.

[0008] As a further implementation, a flared opening is provided at the top of the guide tube.

[0009] As a further implementation, a bearing is provided on the outer surface of the guide tube, and a helical blade is provided on the outside of the bearing.

[0010] As a further implementation, the height of the helical blades is lower than the top of the guide tube.

[0011] As a further implementation, the hollow stabilizer includes a base body, a flip block, and a fixing bolt. The two sides of the base body are connected to the flip block via rotating shafts.

[0012] As a further implementation, a hollow cavity is provided inside the seat, and the flipping block is movably connected to the fixing bolt.

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

[0014] (1) The present invention has a hollow stabilizing seat provided by the outer shell. The hollow design of the hollow stabilizing seat can improve the buoyancy of the present invention, and at the same time avoid the situation where the present invention is deeply mired in the mud in the water and difficult to pull out, reducing the labor intensity and risk of manual handling, and can achieve continuous sinking caused by reducing its own weight, avoiding water inlet blockage and maintenance difficulties.

[0015] (2) The present invention provides a guide pipe by setting a guide pipe on the side wall of the hollow stabilizer. The guide pipe and the water outlet pipe are set on the same central axis. The top of the guide pipe is set with a flared mouth. The flared mouth allows the cable and hose to extend upward from the bottom of the flared mouth. During use, the cable is bent at the edge of the protective pipe and is not easy to wear. The cable will not come into contact with mud and sand in the water and wear. Attached Figure Description

[0023] Example

[0024] This embodiment provides a submersible water pump suction device, such as... Figure 1-4 As shown, the device includes a water pump suction device, which comprises a housing 1 and an outlet pipe 2. The housing 1 serves as the main structure of this application, housing the core components of the submersible pump (such as the impeller and motor), and bearing the liquid pressure and external environmental impact. The outlet pipe 2 is threadedly connected to a flexible hose, which then passes through a guide pipe 5. The outlet pipe 2 is responsible for outputting the pumped liquid from inside the device and transporting it to the target location (such as the ground or a water storage facility) via the flexible hose.

[0025] The outer shell 1 is fitted with a hollow stabilizing seat 3, which is a supporting structure fitted onto the outside of the shell 1. The hollow stabilizing seat 3 increases the contact area with the well wall, preventing the device from tilting or swaying in deep water or sludge environments. The hollow design of the hollow stabilizing seat 3 enhances the buoyancy of the device and avoids the difficulty of pulling it out when it is deeply embedded in sludge, reducing the workload and risk of manual handling. Chinese patent document CN202121605500.X, "A Pile Foundation Slurry and Sludge Separation and Circulation Device," discloses a "suspension cylinder," which requires separate installation or additional construction. This application achieves a stronger, integrated buoyancy device through the integrated design of the hollow stabilizing seat 3. The buoyancy of the hollow stabilizing seat 3 is more concentrated, and the device and components are more compact.

[0026] A positioning device 4 is installed inside the hollow stabilizing base 3. The positioning device 4 is vertically arranged and made of rubber. The top and sides of the positioning device 4 abut against the housing 1 of this application (that is, the positioning device 4 plays a better fixing role and also prevents wear on the outer surface of the housing 1). The positioning device 4 is used to fix the vertical relative position of this application and the hollow stabilizing base 3, and prevents sinking or displacement due to water flow impact or the weight of the device. A guide pipe 5 is installed on the side wall of the hollow stabilizing base 3. The guide pipe 5 is arranged on the same central axis as the water outlet pipe 2. The guide pipe 5 provides an independent channel for the hose and cable, avoiding friction between the hose and cable and the well wall or external obstacles during use, reducing the risk of damage to the water outlet hose or wear of the wire insulation. The coaxial design ensures smooth water flow between the water outlet pipe 2 and the guide pipe 5, reducing energy loss or failure caused by water flow bends.

[0027] A cable through-hole 6 is provided on the bottom side wall of the guide pipe 5. The cable through-hole 6 is connected to the bottom of the cable conduit 12, which is located on the inner wall of the guide pipe 5. When the device is submerged in deep water or sludge, the cable through-hole 6 allows the cable to pass through the side wall of the guide pipe 5 and then run upwards along the inner cavity of the cable conduit 12, instead of the cable being directly exposed to the external water flow, preventing high-pressure liquid flow or silt from washing away the cable surface. The cable through-hole 6 confines most of the cable within the guide pipe 5, avoiding direct friction between the cable and hard objects such as the well wall and silt, reducing the risk of damage to the cable insulation layer. The dedicated cable through-hole 6 and cable conduit 12 separate the cable from the outlet hose, preventing them from tangling or squeezing each other, ensuring that water flow and power transmission do not interfere with each other.

[0028] The top of the guide tube 5 is provided with a flared opening 11, which allows the cable and hose to extend upward from the bottom of the flared opening 11. In the prior art, the outer shell of the cable tube is a hollow cylinder. At the part where the outer shell of the cable tube contacts the cable, the cable insulation layer is easily rubbed back and forth and damaged. For example, in Chinese patent CN202220350360.4 "A cable fixing and protection device", the upper and lower protective cylinders position the cable fixing clamp, and the edges of the upper and lower protective cylinders wear against the cable insulation layer, which can easily lead to the cracking of the outer insulation layer of the cable.

[0029] Meanwhile, this application provides a flared opening 11 at the top of the guide tube 5 (the flared opening 11 has a large upper opening and a small lower opening, with the lower opening connected to the top of the guide tube 5). This design ensures that the edge of the guide tube 5 will not come into contact with the cable or hose for wear. In other words, during use, the cable is less likely to be worn when it is bent at the edge of the protective tube. Because of the guide tube 5, the cable through hole 6, and the cable conduit 12, the cable will not come into contact with mud and sand in the water for wear.

[0030] A bearing 9 is provided on the outer surface of the guide pipe 5, and a helical blade 10 is provided on the outer side of the bearing 9. The bearing 9 supports the rotation of the helical blade 10, reducing frictional loss between the helical blade 10 and the guide pipe 5. When the helical blade 10 rotates, it can agitate the sludge around the application, preventing the application housing 1 from getting stuck in the silt and difficult to pull out. Moreover, when the side flow velocity is high, the kinetic energy of the side water flow is converted into the rotational mechanical energy of the helical blade 10, thus avoiding the application from swaying when the side water flow velocity is high. The submerged pump body in the prior art basically does not consider the negative impact of the side water flow, so the prior art has not disclosed a corresponding technical solution. The rotatable design of the helical blade 10 in this application (absorbing the potential energy of the water flow) achieves the effect of reducing the swaying of the application.

[0031] The height of the spiral blade 10 is lower than the top of the guide tube 5. The limited height of the spiral blade 10 can prevent excessively agitated impurities from entering the guide tube 5 and reduce the risk of pipeline blockage.

[0032] The hollow stabilizer 3 includes a base body 31, a flip block 32, and a fixing bolt 33. The base body 31 is connected to the flip block 32 on both sides via rotating shafts 7. The flip block 32 can rotate around the base body 31 via the rotating shafts 7, simplifying the assembly process of the hollow stabilizer 3. The base body 31 has a hollow cavity 8 (i.e., the hollow cavity 8 is internal), which provides buoyancy in water, preventing the device from sinking into silt due to its own weight and becoming difficult to remove. The flip block 32 is movably connected to the fixing bolt 33 (specifically, a threaded connection). During installation, the fixing bolt 33 is first opened, then the flip block 32 is unfolded. The base body 31 and the flip block 32 are then placed around the housing 1, and finally the fixing bolt 33 is secured. The device is then placed in water for operation.

[0033] The submersible pump suction device in this application specifically refers to a vertical submersible pump.

[0034] The length, height, and curvature of the lines of the positioning device 4, guide tube 5, bearing 9, and spiral blade 10 in the attached drawings are for illustrative purposes only, and those skilled in the art can make adaptive adjustments according to actual usage.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
