Description

Technical Field

[0001] This utility model belongs to the field of water pump technology, and relates to a vertical water pump, particularly a vertical water pump motor fan cover. Background Technology

[0002] A vertical water pump is a commonly used industrial water pump that uses an electric motor to convert mechanical energy into the kinetic energy of the liquid, thereby enabling the liquid to be transported.

[0003] An existing vertical water pump, such as the vertical daily water pump disclosed in the Chinese Patent Database (application number: 201822127163.2), includes a pump body shell and a metal base. The pump body shell is fixedly mounted on the upper end of the metal base. A water inlet connection pipe is provided at the left end of the pump body shell, and a water outlet connection pipe is provided at the right end of the pump body shell. A pump body connecting ring is provided at the upper end of the pump body connecting ring, and a connecting metal ring is provided at the upper end of the connecting metal ring. A motor body is provided at the upper end of the connecting metal ring, and a metal heat sink is provided around the outer perimeter of the motor body. A motor fan cover is provided at the upper end of the motor fan cover, and a shielding arc-shaped cover is provided at the upper end of the motor fan cover. The shielding arc-shaped cover is fixed to the motor fan cover by adjusting bolts. The motor body is electrically connected to an external power source.

[0004] The aforementioned water pump uses an additional curved shield to cover the motor fan housing, mainly to prevent hard objects from entering through the air holes on the top surface of the fan housing and damaging the impeller. However, in the actual design, there is a certain gap between the curved shield and the motor fan housing, which increases the overall height of the water pump and occupies more space. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a vertical water pump motor shroud that reduces space occupancy.

[0006] The purpose of this utility model can be achieved through the following technical solution: A vertical water pump motor fan cover, including a cover body, the inner cavity of the cover body is used to accommodate the motor fan blades, characterized in that the top surface of the cover body is recessed downward to form numerous notches, and the notches are densely distributed in the middle of the top surface of the cover body; an air inlet is provided on the side wall of the notch, the air inlet is located in the inner cavity of the cover body and is set close to the edge of the notch; each notch is connected to the inner cavity of the cover body through a corresponding air inlet.

[0007] When in use, the fan blades are driven by the motor shaft, and the gas enters the cover through the recessed inner cavity and the air inlet, and then is discharged through the gap between the lower end of the cover and the motor barrel.

[0008] The top surface of the cover is recessed to form a notch, and the air inlet that connects the inner cavity of the cover to the outside is located on the side wall of the notch. This effectively prevents hard objects from entering the cover, thereby reducing the chance of damage to the fan blades.

[0009] The top surface of the cover is recessed to form a notch, and the air inlet is located in the inner cavity of the cover. This allows the overall height of the cover to remain basically unchanged in actual design. Compared with existing technologies, this can greatly reduce the overall height of the vertical water pump and reduce space occupation.

[0010] In the aforementioned vertical water pump motor shroud, the air inlet is an arc shape coaxial with the corresponding recess, so as to increase the air intake volume and accelerate the heat dissipation of the motor by enlarging the size of the air inlet.

[0011] In the aforementioned vertical water pump motor shroud, each recess has two air inlets on its side wall, and the two air inlets are evenly distributed around the central axis of the corresponding recess.

[0012] In the aforementioned vertical water pump motor fan cover, a raised ring is formed on the top surface of the cover, and all the recesses are located within the raised ring. The raised ring is designed to protect the recesses from the side, further reducing the chance of external hard objects entering the cover and providing better protection for the fan blades.

[0013] In the aforementioned vertical water pump motor shroud, the axial cross-section of the convex ring is arc-shaped to enhance the strength of the top surface of the shroud.

[0014] Compared with existing technologies, this vertical water pump motor fan cover has the following advantages:

[0015] 1. The top surface of the cover is recessed to form a notch, and the air inlet that connects the inner cavity of the cover to the outside is located on the side wall of the notch. This effectively prevents hard objects from entering the cover, thereby reducing the chance of damage to the fan blades.

[0016] 2. The design incorporates a raised ring to provide lateral protection against the recess, further reducing the likelihood of external hard objects entering the enclosure and providing better protection for the fan blades.

[0017] 3. The top surface of the cover is recessed to form a notch, and the air inlet is located in the inner cavity of the cover. This allows the overall height of the cover to remain basically unchanged in actual design. Compared with existing technologies, this can greatly reduce the overall height of the vertical water pump and reduce space occupation. Attached Figure Description

[0021] In the diagram, 1 is the cover; 1a is the notch; 1b is the air inlet; 1c is the convex ring; 2 is the fan blade; and 3 is the barrel. Detailed Implementation

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1 As shown, this vertical water pump motor fan cover includes a cover body 1. In use, the cover body 1 is set with the opening facing downwards, and the inner cavity of the cover body 1 is used to accommodate the motor fan blades 2.

[0024] Specifically

[0025] like Figure 2 and Figure 3 As shown, the top surface of the cover 1 is recessed downwards to form numerous notches 1a, which are densely distributed in the middle of the top surface of the cover 1. The notches 1a extend into the inner cavity of the cover 1, and air inlets 1b are provided on the side walls of the notches 1a. The air inlets 1b are located in the inner cavity of the cover 1 and are positioned close to the edge of the notches 1a. Each notch 1a is connected to the inner cavity of the cover 1 through a corresponding air inlet 1b.

[0026] When in use, the fan blade 2 is driven by the motor shaft. The gas enters the cover 1 through the inner cavity of the notch 1a and the air inlet 1b, and then is discharged through the gap between the lower end of the cover 1 and the motor barrel 3.

[0027] The top surface of the cover 1 is recessed to form a notch 1a, and the air inlet 1b that connects the inner cavity of the cover 1 to the outside is located on the side wall of the notch 1a. This can effectively prevent the probability of external hard objects entering the cover 1, thereby reducing the probability of damage to the fan blade 2.

[0028] The top surface of the cover 1 is recessed to form a notch 1a, and the air inlet 1b is located in the inner cavity of the cover 1. In actual design, the overall height of the cover 1 can remain basically unchanged. Compared with the existing technology, this can greatly reduce the overall height of the vertical water pump and reduce space occupation.

[0029] To further explain, the air inlet 1b is an arc shape coaxial with the corresponding recess 1a, so as to increase the air intake volume and accelerate the heat dissipation of the motor by increasing the size of the air inlet 1b. In the actual product, each recess 1a has two air inlets 1b on its side wall, and the two air inlets 1b are evenly distributed around the central axis of the corresponding recess 1a.

[0030] Furthermore, such as Figure 2 and Figure 3As shown, a raised ring 1c is formed on the top surface of the cover 1, and all the recesses 1a are located within the raised ring 1c. The raised ring 1c is designed to protect the recesses 1a laterally, further reducing the probability of external hard objects entering the cover 1 and providing better protection for the fan blades 2. Preferably, the axial cross-section of the raised ring 1c is arc-shaped to enhance the strength of the top surface of the cover 1.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
