Description
Technical Field
[0001] The utility model relates to the technical field of water pumps, in particular to a straight-blade type wind leaf for a water pump. Background Art
[0002] Water pumps are common devices in industrial and agricultural production, mainly used to transport liquids from one place to another. The motor is one of the core structures of the water pump. Its output shaft drives the impeller to rotate, creating a vacuum state in the central part of the impeller, and then enabling the liquid to pass through the central part of the impeller and finally be discharged. A large amount of heat is generated during the operation of the motor. If it is not dissipated in time, it is very likely to cause the motor to malfunction or even be scrapped. Therefore, a wind leaf is provided at one end of the motor far from the output shaft for heat dissipation. Traditional wind leaves are similar to the fans commonly seen in daily life, mainly using curved blades. A single curved blade requires a relatively large amount of space, so the number of blades is limited, and it is difficult to improve the heat dissipation effect of the wind leaf. In addition, the processing and assembly of the curved blades are very cumbersome. Based on this situation, how to improve the heat dissipation effect of the wind leaf and simplify the processing of the wind leaf has increasingly become an urgent problem for relevant technical personnel. Content of the Utility Model
[0003] In order to solve the above technical problems, the utility model provides a straight-blade type wind leaf for a water pump.
[0004] A straight-blade type wind leaf for a water pump includes a back cover. It is characterized in that: an upper connecting part and a lower connecting part are arranged at the central position of the back cover. The upper connecting part is located at the upper part of the back cover, and the lower connecting part is located at the lower part of the back cover. The upper connecting part and the lower connecting part are of an integral structure. A connecting hole is penetrated through the central positions of the upper connecting part and the lower connecting part. The outer periphery of the lower connecting part is provided with blades in a radially equidistant annular arrangement. The blades are of an integral structure with the lower connecting part and the back cover. The blades are straight plate-shaped.
[0005] Further, the whole back cover is in the shape of a concave arc-shaped curved surface.
[0006] Further, the blade includes an inner horizontal section, a transition section, and an outer horizontal section. The transition section is of an inclined structure. The width of the inner horizontal section is less than or equal to the width of the transition section. The width of the transition section is less than or equal to the width of the outer horizontal section.
[0007] Further, an inner transverse groove is arranged at the lower part of the inner horizontal section, and an outer transverse groove is arranged at the lower part of the outer horizontal section.
[0008] Further, square holes are symmetrically penetrated through both sides of the upper connecting part inside the back cover.
[0009] Further, a protective ring is arranged between the upper part of the back cover, the upper connecting part and the square hole. The protective ring is of an integral structure with the back cover.
[0010] Furthermore, the connection positions between the blade and the back cover and the lower connecting part are all rounded corner structures.
[0011] The beneficial effects of a straight - blade type wind blade for a water pump of the present utility model are as follows:
[0012] 1. The blade is in a straight - plate shape, and the space occupied by a single blade is significantly reduced, so that the number of blades can be significantly increased. The inner horizontal section is less than or equal to the transition section and less than or equal to the outer horizontal section in terms of the combined width of the concave - arc curved surface of the whole back cover, providing a good structural basis for the smooth flow of air between the blades. Thus, with the increase in the overall number of blades, each single blade can fan a larger area, and the air flows smoothly, and the heat dissipation effect is significantly improved compared with the traditional curved - surface blades;
[0013] 2. Compared with the curved - surface blades, the straight - plate - shaped blades have a more concise structure, and the processing is correspondingly simplified;
[0014] 3. The rounded - corner structures at the connection positions between the blade and the back cover and the lower connecting part effectively ensure the strength of the blade and the whole wind blade. The protective ring effectively enhances the strength of the back cover and the whole wind blade. The integral structure of the upper connecting part and the lower connecting part and the connecting holes inside provide a good structural basis for the stable installation of this wind blade, thus effectively ensuring the stability and safety in use of this wind blade;
[0015] 4. During the working process of this wind blade, both the back cover and the blade tend to be thermally deformed. The square holes, inner transverse grooves, and outer transverse grooves effectively relieve this trend, thus effectively ensuring the normal operation of this wind blade in a hot environment.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] For clearer illustration, in combination with the accompanying drawings of the specification, a straight - blade type wind blade for a water pump of the present utility model will be further described.
[0022] A straight - blade type wind blade for a water pump, including a back cover 3, is characterized in that: an upper connecting part 2 and a lower connecting part 6 are arranged at the central position of the back cover 3. The upper connecting part 2 is located at the upper part of the back cover 3, and the lower connecting part 6 is located at the lower part of the back cover 3. The upper connecting part 2 and the lower connecting part 6 are of an integral structure. Connecting holes are penetrated through the central positions of the upper connecting part 2 and the lower connecting part 6. Blades 1 are arranged in a radially equidistant annular shape around the lower connecting part 6. The blades 1 and the lower connecting part 6 and the back cover 3 are of an integral structure, and the blades 1 are straight - plate shaped.
[0023] Furthermore, the whole back cover 3 is in the shape of a concave - down curved surface.
[0024] Furthermore, the blade 1 includes an inner horizontal section 9, a transition section 10, and an outer horizontal section 11. The transition section 10 is of an inclined structure. The width of the inner horizontal section 9 is less than or equal to the width of the transition section 10, and the width of the transition section 10 is less than or equal to the width of the outer horizontal section 11.
[0025] Furthermore, an inner transverse groove 7 is arranged at the lower part of the inner horizontal section 9, and an outer transverse groove 8 is arranged at the lower part of the outer horizontal section 11.
[0026] Furthermore, square holes 5 are symmetrically penetrated through the inside of the back cover 3 and on both sides of the upper connecting part 2.
[0027] Furthermore, a protective ring 4 is arranged between the upper part of the back cover 3, the upper connecting part 2 and the square hole 5. The protective ring 4 and the back cover 3 are of an integral structure.
[0028] Furthermore, the connection positions of the blade 1 with the back cover 3 and the lower connecting part 6 are all of rounded - corner structures.
[0029] The working principle of a straight - blade type wind blade for a water pump of the present utility model is as follows: The wind blade is installed at one end of the water pump motor away from its output shaft through the connection holes at the central positions of the upper connection part 2 and the lower connection part 6. When the water pump motor is started, the wind blade starts and rotates synchronously. The overall concave - arc curved surface of the back cover 3, the inner horizontal section 9, the transition section 10, and the outer horizontal section 11 of the straight - plate - shaped blade 1 being integrated as a whole and the related width design provide centrifugal force for the air, enabling it to flow smoothly between the blades 1 and exhaust axially, thereby dissipating the heat generated during the operation of the water pump motor. The rounded - corner structure at the connection positions of the blade 1 with the back cover 3 and the lower connection part 6 enables the blade 1 and the whole wind blade to always maintain sufficient strength. The retaining ring 4 enables the back cover 3 and the whole wind blade to always maintain sufficient strength. The square hole 5, the inner transverse groove 7, and the outer transverse groove 8 always relieve the tendency of the back cover 3 and the blade 1 to thermally deform, so that the wind blade can also operate normally in a hot environment.
[0030] The above is only the specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
