Abstract
Description
Technical Field
[0001] This utility model relates to the field of water pump technology, specifically a water pump equipped with a flow guide cover. Background Technology
[0002] A water pump equipped with a flow guide is a high-efficiency fluid transport device with a flow guide structure added before the impeller inlet. This design is not the core power component of the water pump, but rather a sophisticated fluid dynamics optimization device. Its main purpose is to guide and optimize the water flow entering the impeller, thereby significantly improving the overall performance, efficiency, and stability of the water pump. It is widely used in applications with high requirements for energy consumption, noise, and operational stability. Adding a flow guide to the water pump is a highly effective technique. By optimizing the flow pattern at the "first gate" of the inlet, it brings about a comprehensive improvement in efficiency, stability, and lifespan with a relatively simple structure. In today's global context of emphasizing energy conservation, emission reduction, and sustainable development, water pumps using this type of high-efficiency hydraulic model have become an important development trend and technological choice in the field of fluid transport. However, existing water pumps equipped with flow guides still have certain shortcomings. While traditional water pumps with deflectors can be used effectively, their filters are typically single-layered and fixed. Once the mesh becomes clogged with debris, cleaning is inconvenient and affects water intake efficiency, leading to decreased pump efficiency or even dry running and damage. Fixed inlets are prone to clogging when faced with floating objects, aquatic plants, and other debris in the water, and lack a buffer structure, allowing water flow impacts to directly affect the pump body. Furthermore, the length of the deflector cannot be adjusted, making it unsuitable for different operating scenarios and lacking flexibility, which often troubles users. Summary of the Invention
[0003] The purpose of this utility model is to provide a water pump equipped with a flow guide cover, in order to solve the problems mentioned in the background art. The filter screen of traditional water pumps is usually single-layered and fixed. Once the mesh is blocked by debris, it is inconvenient to clean and will affect the water intake efficiency, resulting in a decrease in water pump efficiency or even dry running and damage. The fixed water inlet is easy to be blocked when facing floating objects, aquatic plants and other debris in the water, and there is no buffer structure. The water flow impact may directly act on the pump body. In addition, the length of the flow guide cover cannot be adjusted, which cannot adapt to different operating scenarios and has poor flexibility, often troubling users.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a water pump with a flow guide cover, comprising a power source and an adjustable buffer structure, wherein the adjustable buffer structure is provided on the left side of the power source, and the power source comprises a pump body, a first flange, a second flange, fixing bolts, a connecting pipe, a flow guide cover, a fixing bracket, filter holes and a first filter screen; The adjustable buffer structure includes a fixed base, a lead screw, a slide bar, a first metal sleeve, a bellows, a second metal sleeve, and a second filter screen; A first flange is fixedly installed on the left wall of the pump body, and a second flange is provided on the left side of the first flange. The first flange and the second flange are fixedly connected by fixing bolts. A connecting pipe is fixedly installed on the left wall of the second flange, and a flow guide is fixedly installed on the left side of the connecting pipe.

[0006] As a preferred embodiment of this utility model, four sets of fixing seats are evenly fixedly installed on the flow guide cover. The upper two sets of fixing seats are rotatably connected to lead screws, and the other three sets of fixing seats are fixedly installed with sliding rods.
[0007] As a preferred embodiment of this utility model, a first metal sleeve is threaded onto the lead screw, the first metal sleeve and the slide rod are connected in a through-sliding connection, and a corrugated pipe is fixedly installed on the left wall of the first metal sleeve.
[0008] As a preferred embodiment of this utility model, a second metal sleeve is fixedly installed on the left wall of the corrugated pipe, and the second metal sleeve is the same size as the first metal sleeve.
[0009] As a preferred embodiment of this utility model, a second filter screen is fixedly installed on the left wall of the second metal sleeve, and the through holes on the second filter screen are slightly larger than the through holes on the first filter screen.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This water pump equipped with a flow guide cover achieves two-stage filtration by setting a second filter screen and a first filter screen, effectively preventing impurities from entering the pump body and extending the service life of the water pump. Through the screw and bellows structure, the filter screen spacing can be adjusted according to actual needs to adapt to different water quality and flow conditions, enhancing applicability. When a large object moves to the left side of the equipment according to the water flow, due to the excessive power of the pump body, the large object moves at a high speed and will impact the adjustable buffer structure. During the impact, the bellows fixedly installed between the first metal sleeve and the second metal sleeve can buffer the impact of the large object, prevent equipment damage, improve the service life of the equipment, reduce the maintenance frequency of the equipment, and facilitate daily use by users.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figure 1-3 This utility model provides a technical solution: a water pump with a flow guide shroud, including a power source 1 and an adjustable buffer structure 2. The adjustable buffer structure 2 is provided on the left side of the power source 1. The power source 1 includes a pump body 101, a first flange 102, a second flange 103, a fixing bolt 104, a connecting pipe 105, a flow guide shroud 106, a fixing bracket 107, a filter hole 108, and a first filter screen 109. The adjustable buffer structure 2 includes a fixed base 201, a lead screw 202, a slide bar 203, a first metal sleeve 204, a bellows 205, a second metal sleeve 206, and a second filter screen 207. A first flange 102 is fixedly installed on the left wall of the pump body 101. A second flange 103 is provided on the left side of the first flange 102. The first flange 102 and the second flange 103 are fixedly connected by fixing bolts 104. A connecting pipe 105 is fixedly installed on the left wall of the second flange 103. A flow guide shroud 106 is fixedly installed on the left side of the connecting pipe 105.
[0015] Two sets of fixed brackets 107 are fixedly installed on the flow guide 106. A filter hole 108 is opened on the left side of the flow guide 106. A first filter screen 109 is fixedly installed on the left wall of the flow guide 106 by fixing bolts 104.
[0016] Four sets of fixing seats 201 are evenly fixedly installed on the fairing 106. The two sets of fixing seats 201 at the top are rotatably connected to the lead screws 202, and the other three sets of fixing seats 201 are fixedly installed with slide rods 203.
[0017] The lead screw 202 is threaded with a first metal sleeve 204, which is slidably connected to the slide rod 203. A bellows 205 is fixedly installed on the left wall of the first metal sleeve 204.
[0018] A second metal sleeve 206 is fixedly installed on the left wall of the corrugated pipe 205. The second metal sleeve 206 has the same size as the first metal sleeve 204.
[0019] The second filter screen 207 is fixedly installed on the left wall of the second metal sleeve 206. The through holes on the second filter screen 207 are slightly larger than the through holes on the first filter screen 109.
[0020] Working principle: When using a water pump equipped with a flow guide shroud, the water first passes through the second filter screen 207 in the adjustable buffer structure 2 for preliminary filtration, blocking larger impurities from entering. Subsequently, the water flows through the corrugated pipe 205 into the interior of the flow guide shroud 106, and then passes through the first filter screen 109 for secondary filtration, further removing fine impurities and ensuring the cleanliness of the water entering the pump body 101. The adjustable buffer structure 2, through the threaded engagement of the lead screw 202 and the first metal sleeve 204, can adjust the distance between the second filter screen 207 and the first filter screen 109. When the lead screw 202 is rotated, the first metal sleeve 204 slides along the slide bar 203, causing the bellows 205 to extend and retract, thereby adjusting the position of the second filter screen 207 to adapt to the water flow buffering and filtration requirements under different working conditions; When a large object moves to the left side of the equipment due to the water flow, the large object moves at a high speed due to the excessive power of the pump body 101, and will impact the adjustable buffer structure 2. During the impact, the bellows 205 fixedly installed between the first metal sleeve 204 and the second metal sleeve 206 can buffer the impact of the large object and prevent damage to the equipment. The guide shield 106 is stably supported by the fixed bracket 107. Its structural design helps to guide the water flow smoothly into the pump body 101, reduce eddies and energy loss, and improve the operating efficiency of the pump body 101, thereby completing a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
