Description

Technical Field

[0001] This utility model relates to the field of electric motor technology, and specifically to a wind guide cover. Background Technology

[0002] Currently available air guide covers are mostly located at the fan end of the electric motor, while the front bearing and end cover of the motor cannot be guided by air, relying mainly on natural ventilation. When the front bearing temperature is high, it cannot be adequately cooled. At the same time, when the motor body is covered with dust and debris, the air cannot fully contact the motor heat sink, resulting in a sharp decrease in heat dissipation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wind deflector with better overall heat dissipation effect.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a wind guide cover, including a fan cover and a wind deflector, one end of the fan cover and one end of the wind deflector are connected, and the wind deflector extends along the axial direction of the fan cover in a direction away from the other end of the fan cover.

[0005] The beneficial effects of this utility model are as follows: By setting a fan cover installed at the rear end of the motor and a wind deflector installed above the motor body, a complete air duct from the rear end to the front end of the motor can be formed. This ensures that after the air is blown out by the cooling fan at the rear end of the motor, the airflow can be guided to the front bearing and end cover of the motor, solving the problem that the existing fan cover cannot guide airflow to this area, and achieving effective heat dissipation for the front bearing and end cover of the motor. At the same time, when in use, the wind deflector is placed on the upper end of the motor body, which can be used to block dust, lint, and other falling objects, preventing dust, lint, etc. from forming a heat insulation layer on the heat sink of the motor and hindering heat dissipation. The setting of the wind deflector further improves the heat dissipation efficiency.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a wind guide plate is fixedly provided at the other end of the windshield, and the wind guide plate is inclined inward along the radial direction of the windshield.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the downward-sloping air guide plate can accurately guide the airflow to the front bearing and end cover area of ​​the motor, making up for the deficiency of insufficient natural ventilation in this area in the prior art.

[0009] Furthermore, the windshield is an arc-shaped plate.

[0010] The beneficial effects of adopting the above-mentioned further solution are: setting the windshield as an arc-shaped plate can reduce airflow resistance, allowing the air to flow more smoothly from the fan cover to the front end of the motor, improving the heat dissipation efficiency of the front bearing and end cover; at the same time, the arc-shaped surface can maintain a certain degree of concentration of airflow before diffusion, thereby better dissipating heat from the motor body.

[0011] Furthermore, the fan cover is a cylindrical shape with one end open and the other end closed.

[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: the fan cover is set as a cylindrical shape with one end open and the other end closed, which makes it convenient for the fan cover to be placed on the rear end of the motor. The other end is closed, thereby collecting the wind power generated by the motor's fan and preventing a large amount of airflow from leaking out from the closed end of the fan cover. This ensures the concentration and stability of the airflow inside the fan cover, thereby improving the air guiding effect. At the same time, this cylindrical structure is easy to install and cooperate with other components, ensuring the compactness and rationality of the overall structure of the air guide cover.

[0013] Furthermore, heat dissipation holes are provided on the end face of the other end of the fan cover.

[0014] The beneficial effects of adopting the above-mentioned further solution are: by setting heat dissipation holes at the other end of the fan, while ensuring that the airflow inside the fan cover is stably delivered to the windshield, the heat generated by the fan during operation can be dissipated in a timely manner, avoiding the accumulation of heat inside the fan cover, which would affect the normal working performance and service life of the fan; the design of the heat dissipation holes balances the needs of air guiding and heat dissipation, and improves the reliability and stability of equipment operation.

[0015] Furthermore, the fan cover includes a first section cover, a second section cover, and a baffle. The first section cover is conical, the second section cover is cylindrical, and the baffle is fixedly connected to one end of the first section cover and closes the end of the first section cover. The other end of the first section cover is connected to one end of the second section cover.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: the structural design of the fan cover ensures better compatibility with the motor, while the conical first section cover can converge the airflow entering the fan cover, allowing the airflow to smoothly enter the cylindrical second section cover, and the cylindrical second section cover can stabilize the airflow direction, ensuring that the airflow is delivered to the windshield cover evenly and stably; the baffle seals the end of the first section cover to prevent airflow from leaking back, thus enhancing the air guiding effect of the fan cover.

[0017] Furthermore, the diameter of the first section of the cover gradually increases from one end to the other.

[0018] The beneficial effects of adopting the above-mentioned further scheme are: the design of the diameter of the first section cover gradually increasing from one end to the other can make the airflow gradually accelerate after entering the fan cover, ensuring that the airflow flows more smoothly to the second section cover, thereby improving the transmission efficiency and stability of the airflow in the fan cover, and further improving the overall air guiding performance of the air guide cover.

[0019] Furthermore, one end of the fan cover and one end of the windshield are connected by a connecting assembly, which includes a connector and a locking member; the connector includes a first connecting piece, a second connecting piece, and an adapter piece, one end of the first connecting piece and one end of the adapter piece are hinged together, the other end of the first connecting piece is connected to one end of the windshield and fixed by the locking member, the other end of the adapter piece and one end of the second connecting piece are hinged together, the other end of the second connecting piece is connected to one end of the fan cover and fixed by the locking member; the locking member is a screw.

[0020] The advantages of adopting the above-mentioned further solution are: the fan cover and the wind deflector are connected by a connecting assembly containing connectors and locking parts, which is simple in structure and easy to install and disassemble. When it is necessary to repair, replace parts or adjust the installation position of the wind deflector, the fan cover and the wind deflector can be easily separated simply by loosening the screws; at the same time, the hinged connector design increases the flexibility of the wind deflector installation.

[0021] Furthermore, one end of the windshield is provided with a first threaded hole, the other end of the first connecting piece is provided with a second through hole, the other end of the second connecting piece is provided with a third through hole, one end of the fan cover is provided with a fourth threaded hole, the second through hole and the first threaded hole are detachably connected by screws, and the third through hole and the fourth threaded hole are detachably connected by screws.

[0022] The beneficial effect of adopting the above-mentioned further solution is that by setting threaded holes on the windshield and fan cover, setting through holes on the connector, and using screws to achieve detachable connection, this structural design further ensures the firmness and stability of the connection.

[0023] Furthermore, a fifth through hole is provided in the middle of the windshield.

[0024] The beneficial effect of adopting the above-mentioned further solution is that by setting the fifth through hole, the lifting ring on the motor is cleverly utilized, thereby fixing the lifting ring to the motor through the fifth through hole and fixing the entire air guide cover to the motor body more reliably.

[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0034] like Figures 1-5 As shown, this embodiment provides an air guide cover, including a fan cover 100 and a wind deflector 200. One end of the fan cover 100 and one end of the wind deflector 200 are connected. The wind deflector 200 extends along the axial direction of the fan cover 100 in a direction away from the other end of the fan cover 100.

[0035] By setting a fan cover 100 installed at the rear end of the motor 1 and a wind deflector 200 installed on the top of the motor 1 body, a complete air duct from the rear end to the front end of the motor 1 can be formed. This ensures that after the air is blown out by the cooling fan at the rear end of the motor 1, the airflow can be guided to the front bearing and end cover of the motor 1, solving the problem that the existing fan cover 100 cannot guide airflow to this area, and achieving effective heat dissipation for the front bearing and end cover of the motor 1. At the same time, when in use, the wind deflector 200 is placed on the top of the motor 1 body, which can be used to block dust, flying lint and other falling objects, preventing dust, flying lint and other objects from forming a heat insulation layer on the heat sink of the motor 1 and hindering the dissipation of heat. The setting of the wind deflector 200 further improves the heat dissipation efficiency.

[0036] The windshield 200 extends in a direction parallel to the axis of the fan cover 100.

[0037] Specifically, one end of the fan cover 100 and one end of the windshield cover 200 can be fixedly connected, hinged, or detachably connected.

[0038] Based on any of the above technical solutions, a wind guide plate 210 is fixedly provided at the other end of the wind shield 200, and the wind guide plate 210 is inclined inward along the radial direction of the wind shield 200.

[0039] The downward-sloping air guide plate 210 can precisely direct the airflow to the front bearing and end cover area of ​​the motor 1, making up for the lack of natural ventilation in this area in the prior art.

[0040] Based on any of the above technical solutions, the windshield 200 is an arc-shaped plate.

[0041] Setting the windshield 200 as an arc-shaped plate can reduce airflow resistance, allowing the air to flow more smoothly from the fan cover 100 to the front end of the motor 1, improving the heat dissipation efficiency of the front bearing and end cover; at the same time, the arc-shaped surface can maintain a certain degree of concentration of airflow before diffusion, thereby better dissipating heat from the motor 1 body.

[0042] Specifically, the concave surface of the arc-shaped plate faces the main body of the motor 1.

[0043] Optionally, the windshield 200 can also be a flat plate or a bent plate.

[0044] In a specific example, one end of the air guide plate 210 is fixedly connected to the other end of the windshield 200, and the other end of the air guide plate 210 is bent toward the center of the windshield 200.

[0045] Based on any of the above technical solutions, the fan cover 100 is a cylindrical shape with one end open and the other end closed.

[0046] The fan cover 100 is designed as a cylindrical shape with one end open and the other end closed, which facilitates the fan cover 100 being placed over the rear end of the motor 1. The other end is closed, thereby collecting the air force generated by the fan of the motor 1 and preventing a large amount of airflow from leaking out from the closed end of the fan cover 100. This ensures the concentration and stability of the airflow within the fan cover 100, thereby improving the air guiding effect. At the same time, this cylindrical structure facilitates the installation and cooperation with other components, ensuring the compactness and rationality of the overall structure of the air guide cover.

[0047] Based on any of the above technical solutions, a heat dissipation hole 131 is provided on the end face of the other end of the fan cover 100.

[0048] By providing a heat dissipation hole 131 on the other end face of the fan cover 100, the heat generated by the fan during operation can be dissipated in a timely manner while ensuring that the airflow inside the fan cover 100 is stably delivered to the windshield 200. This prevents heat from accumulating inside the fan cover 100 and affecting the normal operation performance and service life of the fan. The design of the heat dissipation hole 131 balances the needs of airflow and heat dissipation, improving the reliability and stability of the equipment operation.

[0049] Based on any of the above technical solutions, the fan cover 100 includes a first section cover 110, a second section cover 120, and a baffle 130. The first section cover 110 is conical, the second section cover 120 is cylindrical, the baffle 130 is fixedly connected to one end of the first section cover 110 and closes the end of the first section cover 110, and the other end of the first section cover 110 is connected to one end of the second section cover 120.

[0050] The structural design of the fan cover 100 ensures better compatibility with the motor 1. The conical first section cover 110 can converge the airflow entering the fan cover 100, allowing the airflow to smoothly enter the cylindrical second section cover 120. The cylindrical second section cover 120 can stabilize the airflow direction, ensuring that the airflow is delivered evenly and stably to the windshield cover 200. The baffle 130 closes the end of the first section cover 110 to prevent airflow from leaking back, thus enhancing the air guiding effect of the fan cover 100.

[0051] Based on any of the above technical solutions, the diameter of the first section cover 110 gradually increases from one end of the first section cover 110 to the other end.

[0052] The design of the first section cover 110, with its diameter gradually increasing from one end to the other, allows the airflow to gradually accelerate after entering the fan cover 100, ensuring that the airflow flows more smoothly to the second section cover 120. This improves the transmission efficiency and stability of the airflow within the fan cover 100, and further enhances the overall airflow guiding performance of the air guide cover.

[0053] Based on any of the above technical solutions, one end of the fan cover 100 and one end of the windshield 200 are connected by a connecting assembly, the connecting assembly including a connector 310 and a locking member; the connector 310 includes a first connecting piece 311, a second connecting piece 312 and an adapter piece 313, one end of the first connecting piece 311 and one end of the adapter piece 313 are hinged together, the other end of the first connecting piece 311 is connected to one end of the windshield 200 and fixed by the locking member, the other end of the adapter piece 313 and one end of the second connecting piece 312 are hinged together, the other end of the second connecting piece 312 is connected to one end of the fan cover 100 and fixed by the locking member; the locking member is a screw.

[0054] The fan cover 100 and the wind deflector 200 are connected by a connecting assembly including a connector 310 and a locking element. This connection method is simple in structure and easy to install and disassemble. When it is necessary to repair the wind deflector, replace parts, adjust the installation position, or clean the heat sink of the motor 1, the fan cover 100 and the wind deflector 200 can be easily separated by simply loosening the screws. At the same time, the hinged connector 310 increases the flexibility of the wind deflector installation, allowing the wind deflector 200 to be folded back or removed according to actual working needs.

[0055] Specifically, the fan cover 100 and the windshield cover 200 have a certain height difference, which can effectively guide the airflow from the rear end of the motor 1 to the front end, and at the same time, it can also use natural wind to ventilate and dissipate heat from the motor 1.

[0056] like Figure 6 As shown, a lifting ring 2 is provided on the motor 1. When the motor 1 is being lifted, the lifting ring 2 serves as the connecting component between the lifting device and the motor 1. The lifting ring fixing seat 3 is used to fix the lifting ring 2, and the lifting ring 2 and the lifting ring fixing seat 3 are detachably connected. Figure 5 As shown, when the windshield 200 is placed on the motor 1, the adapter plate 313 ensures that the windshield 200 provides sufficient clearance for the hanging ring fixing seat 3. At the same time, the two ends of the adapter plate 313 are connected to the first connecting plate 311 and the second connecting plate 312 respectively, thereby connecting the fan cover 100 and the windshield 200 into one unit, effectively guiding the airflow from the rear end of the motor 1 to the front end, and making the fan cover 100 and the windshield 200 have a certain height difference, so that natural wind can be used to ventilate and dissipate heat from the motor 1.

[0057] Based on any of the above technical solutions, one end of the windshield 200 is provided with a first threaded hole, the other end of the first connecting piece 311 is provided with a second through hole, the other end of the second connecting piece 312 is provided with a third through hole, one end of the fan cover 100 is provided with a fourth threaded hole, the second through hole and the first threaded hole are detachably connected by screws, and the third through hole and the fourth threaded hole are detachably connected by screws.

[0058] By providing threaded holes on the windshield 200 and fan cover 100, and through holes on the connector 310, and by using screws to achieve a detachable connection, this structural design further ensures the strength and stability of the connection.

[0059] Based on any of the above technical solutions, a fifth through hole 220 is provided in the middle of the windshield 200.

[0060] By setting the fifth through hole 220, the lifting ring 2 on the motor 1 is cleverly utilized, so that the lifting ring 2 is fixed to the motor 1 through the fifth through hole 220, and the entire air guide cover is more reliably fixed to the motor 1 body.
