Description

Technical Field

[0001] The present invention is an integrated air-cooled modular unit for multi-energy complementary utilization, belonging to the technical field of air-cooled units. Background Art

[0002] Air-cooled means that an air-cooled heat pump is a central air-conditioning unit that uses air as the cold source and water as the cold supply medium. As an integrated device for both cold and heat sources, the air-cooled heat pump saves many accessories such as cooling towers, water pumps, boilers, and corresponding pipeline systems. In the air-cooled unit, a motor is required to drive the fan blade to rotate, so that air flows to the heat exchanger in the air-cooled unit, and heat exchange is carried out between the air and the medium in the heat exchanger. At present, the motor in the air-cooled unit is installed in the air duct by screws, that is, the relative position of the motor and the air duct remains unchanged. Since both the upper and lower ends of the air duct are open, rainwater will enter the air duct on rainy days. Because the position of the motor is fixed, some rainwater will accumulate on the upper surface of the connection part between the motor output shaft and the fan blade and other flat surfaces and the concave parts on the motor surface. The accumulation of rainwater will increase the corrosion rate of the connection parts and affect the service life. Summary of the Invention

The output shaft of the electric motor is arranged downward, and a fan blade is fixedly connected to the output shaft of the electric motor. Two symmetrically arranged supports are installed at the upper part of the air duct. Arc-shaped grooves are opened at the lower parts of the opposite surfaces of the two supports. Two symmetrically arranged support arm rods are installed on the outer surface of the electric motor. An arc-shaped plate matched with the arc-shaped groove is fixedly connected to the end of the support arm rod away from the electric motor. The arc-shaped plate is slidably installed in the arc-shaped groove. Two symmetrically arranged wind shields are installed at the end of the support arm rod away from the electric motor.

[0005] Specifically, two first through holes are opened at the upper parts of the opposite surfaces of the two supports. Two second through holes aligned with the first through holes are opened in the area of the air duct covered by the support. Screws are inserted into the channels formed by the first through holes and the second through holes. One end of the screw extends into the air duct and is threadedly connected to a first nut. The first nut is arranged above the wind shield.

[0006] Specifically, a detachable top plate is installed on the upper surface of the wind shield. A top block for jacking up the first nut is arranged at the upper end of the top plate. The upper surface of the top block is hinged to the upper end of the top plate through a rubber sheet.

[0007] Specifically, a strip groove is provided on the upper surface of the windshield, a threaded column is connected and fixed to the middle position of the lower surface of the top plate, the lower end of the threaded column passes through the strip groove, and the lower end of the threaded column is threadedly connected to a second nut, which is arranged on the side of the windshield away from the top plate.

[0008] Specifically, a counterweight block is clamped on the end of the wind shield away from the support arm rod, the cross-section of the counterweight block is U-shaped, and one side of the counterweight block is threadedly connected to a screw for limiting the relative position of the wind shield and the counterweight block. The interior of the counterweight block is a hollow structure, and a liquid filling port is installed on the upper surface of the counterweight block, and a threaded cover is threadedly connected to the liquid filling port.

[0009] Specifically, a connecting head is connected and fixed to a surface of the windshield close to the support arm, and an end of the connecting head away from the windshield is connected and fixed to the support arm.

[0010] Specifically, a lifting frame is installed in the middle and lower part of the bracket frame, a support plate is installed on the upper surface of the lifting frame, two heat exchangers are provided on the lower side of the air duct, the heat exchanger is installed between the top cover and the support plate, two side panels are provided between the two heat exchangers on the lower side of the air duct, the two side panels on the lower side of the air duct are arranged symmetrically about the air duct, and the side panels are installed between the top cover and the support plate.

[0011] Specifically, a mesh cover is provided on the upper side of the air duct, and the mesh cover is connected and fixed to the air duct by a plurality of screws.

[0012] Beneficial effects of the present invention:

[0013] 1. Insert the two curved plates into the curved grooves on the two supports respectively to achieve sliding contact between the curved plates and the supports. When the motor is working, it drives the fan blades to rotate, so that external air flows into the wind tube, that is, the direction of the airflow is from top to bottom. At this time, when the airflow blows towards the wind shield, the wind force acts on the wind shield to deflect the wind shield, that is, the motor will deflect. At this time, the motor drives the curved plate to slide in the curved groove through the support arm rod. The curved plate and the curved groove work together to limit the amplitude of the motor deflection, thereby avoiding the situation where the fan blades collide with the inner wall of the wind tube. Under the joint action of the motor inertia and the airflow, the motor is deflected back and forth along the trajectory of the curved groove, thereby avoiding rainwater from accumulating on the upper surface of the connection between the motor output shaft and the fan blades and the depressions on the motor surface in rainy days. The residual moisture is quickly dried under the action of the airflow, which slows down the rust rate of the motor and other components and increases the service life.

[0014] 2. Install a top plate on the windshield. When the windshield swings back and forth downward under the action of the airflow, the upward-moving windshield drives the top plate to move upward, so that the top block abuts against the first nut, causing the first nut to rotate clockwise. Then, the deflection of the motor is used to tighten the first nut online to prevent the first nut from loosening. When the top block moves downward, the top block hinges upward around the connection between it and the top plate to avoid the top block causing the first nut to rotate counterclockwise. At the same time, the upward-moving top block cooperates with the first nut to reduce the inertia of the motor and prevent the arc plate from hitting the inner wall of the arc groove with a large force.

[0015] 3. In order to make the first nut tend to rotate clockwise when the top plates on the two wind shields on a support arm move upward, a strip groove is opened on the wind shield, and the position of the threaded column is adjusted along the strip groove. At this time, the relative position of the top plate and the wind shield changes, and then the second nut is used to limit the relative position of the top plate and the wind shield to achieve the adjustment of the relative position of the top plate and the first nut. At this time, the top plates on the two wind shields on a support arm are not symmetrically arranged about the support arm. At this time, the two wind shields on one support arm are in an inclined state. When the airflow flows through the wind duct, the two wind shields on one support arm are subjected to different forces, which makes the motor in an inclined state in the initial state. Therefore, when the motor is started, the inertia of the motor and the airflow cooperate with each other to cause the motor to deflect, thereby achieving the purpose of multi-energy complementary utilization.

[0016] 4. When it is necessary to adjust the inclination angle of the windshield in its initial state, a U-shaped counterweight is clamped on the end of a windshield away from the support arm, and then screws are used to limit the relative position of the counterweight and the windshield. At this time, the two windshields on one support arm are subjected to different forces, thereby changing the inclination angle of the windshield in its initial state. By adding water to the counterweight, it is easy to adjust the initial weight of the counterweight, which is conducive to expanding the range of adjustment of the initial inclination of the windshield.

Detailed implementation manners

[0029] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0030] Please refer to Figures 1 to 4The present invention provides a technical solution: an integrated air-cooling module unit with multi-energy complementary utilization, comprising a bracket frame 1, a detachable top cover 2 is installed on the top of the bracket frame 1, two symmetrically arranged air ducts 3 are installed on the upper surface of the top cover 2, a motor 7 is provided at the upper position of the air duct 3, the output shaft of the motor 7 is arranged downward and a fan blade 12 is connected and fixed to the output shaft of the motor 7, a lifting frame 24 is installed at the middle and lower position of the bracket frame 1, a support plate 23 is installed on the upper surface of the lifting frame 24, two heat exchangers 6 are provided on the lower side of the air duct 3, and the heat exchanger 6 is arranged at the upper part of the air duct 3. Installed between the top cover 2 and the support plate 23, two side panels 5 are provided between the two heat exchangers 6 on the lower side of the wind tube 3, and the two side panels 5 on the lower side of the wind tube 3 are arranged symmetrically about the wind tube 3. The side panels 5 are installed between the top cover 2 and the support plate 23. The design of the two side panels 5 prevents the air flow from flowing between the two heat exchangers 6, and allows the air flow to flow through the heat exchanger 6. A mesh cover 4 is provided on the upper side of the wind tube 3, and the mesh cover 4 is connected and fixed to the wind tube 3 by multiple screws 25. The mesh cover 4 prevents debris from entering the wind tube 3 at will and causing damage to the fan blades 12.

[0031] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 Two symmetrically arranged supports 8 are installed at the upper position of the air duct 3, and two first through-holes 17 are provided at the upper position of the opposite surfaces of the two supports 8. The area of the air duct 3 covered by the supports 8 is provided with two second through-holes aligned with the first through-holes 17. A screw 9 is inserted into the channel formed by the first through-hole 17 and the second through-hole. One end of the screw 9 extends into the air duct 3 and is threadedly connected with a first nut 10. The first nut 10 is provided on the upper side of the wind shield 14. The first nut 10 and the screw 9 cooperate to fix the relative position of the air duct 3 and the support 8.

[0032] See Figures 1-8, the lower positions of the opposite surfaces of the two supports 8 are provided with arc grooves 18, and the outer surface of the motor 7 is equipped with two symmetrically arranged support arm rods 13, and the end of the support arm rod 13 away from the motor 7 is connected and fixed with an arc plate 11 that matches the arc groove 18, and the arc plate 11 is slidably installed in the arc groove 18. The end of the support arm rod 13 away from the motor 7 is equipped with two symmetrically arranged wind shields 14, wherein the wind shield 14 is connected and fixed with a connecting head 22 on a side close to the support arm rod 13, and the end of the connecting head 22 away from the wind shield 14 is connected and fixed to the support arm rod 13, and the connecting head 22 plays the role of connecting the wind shield 14 and the support arm rod 13. The two arc plates 11 are respectively inserted into the arc grooves 18 on the two supports 8 to achieve sliding contact between the arc plate 11 and the support 8. When the motor 7 is working, the fan blades 12 are driven to rotate, so that the external air The air flows into the wind tube 3, that is, the direction of the air flow is from top to bottom. At this time, when the air flow blows towards the wind shield 14, the wind force acts on the wind shield 14 to deflect the wind shield 14, that is, the motor 7 will deflect. At this time, the motor 7 drives the arc plate 11 to slide in the arc groove 18 through the support arm rod 13. The arc plate 11 and the arc groove 18 work together to limit the amplitude of the deflection of the motor 7, thereby preventing the fan blades 12 from colliding with the inner wall of the wind tube 3. Under the combined action of the inertia of the motor 7 and the airflow, the motor 7 is deflected back and forth along the trajectory of the arc groove 18, thereby preventing rainwater from accumulating on planes such as the upper surface of the connection between the output shaft of the motor 7 and the fan blades 12 and the recessed part of the motor surface in rainy days, and the residual moisture is quickly dried under the action of the airflow, slowing down the rusting rate of components such as the motor 7 and improving the service life.

[0033] See Figure 4 、 Figure 6 、 Figure 8 and Fig. 9 At the same time, the upwardly moving top block 19 cooperates with the first nut 10 to reduce the inertia of the motor 7 and prevent the arc plate 11 from hitting the inner wall of the arc groove 18 with a large force.

[0034] See Figure 4 、 Figure 6 、 Figure 8 and Fig. 9 , a strip-shaped groove 15 is formed on the upper surface of the wind deflector 14. A threaded post 21 is fixedly connected to the middle position of the lower surface of the top plate 16. The lower end of the threaded post 21 penetrates through the strip-shaped groove 15. A second nut 20 is threadedly connected to the lower end of the threaded post 21. The second nut 20 is arranged on the side of the wind deflector 14 away from the top plate 16. To make the first nut 10 tend to rotate clockwise when the top plates 16 on the two wind deflectors 14 on one support arm rod 13 move upward, a strip-shaped groove 15 is formed on the wind deflector 14. The position of the threaded post 21 is adjusted along the strip-shaped groove 15. At this time, the relative position between the top plate 16 and the wind deflector 14 changes. Then, the relative position between the top plate 16 and the wind deflector 14 is restricted by the second nut 20, realizing the adjustment of the relative position between the top plate 16 and the first nut 10. At this time, the top plates 16 on the two wind deflectors 14 on one support arm rod 13 are not symmetrically arranged with respect to the support arm rod 13. At this time, the two wind deflectors 14 on one support arm plate are in an inclined state. When the air flow passes through the air cylinder 3, the forces on the two wind deflectors 14 on one support arm rod 13 are different, so that the motor 7 is in an inclined state in the initial state. Thus, when the motor 7 is started, the inertia of the motor 7 and the air flow cooperate with each other to cause the motor 7 to deflect, achieving the purpose of multi-energy complementary utilization.

[0035] Refer to Fig.10 , a counterweight 26 is clamped at one end of the wind deflector 14 away from the support arm rod 13. The cross section of the counterweight 26 is U-shaped. A screw 25 for restricting the relative position between the wind deflector 14 and the counterweight 26 is threadedly connected to one surface of the counterweight 26. The inside of the counterweight 26 is a hollow structure. A liquid filling port 27 is installed on the upper surface of the counterweight 26. A threaded cap 28 is threadedly connected to the liquid filling port 27. When it is necessary to adjust the inclination angle of the wind deflector 14 in the initial state, a U-shaped counterweight 26 is clamped at one end of one wind deflector 14 away from the support arm rod 13. Then, the relative position between the counterweight 26 and the wind deflector 14 is restricted by the screw 25. At this time, the forces on the two wind deflectors 14 on one support arm rod 13 are different, so that the inclination angle of the wind deflector 14 in the initial state changes. By adding water into the counterweight 26, it is convenient to adjust the initial weight of the counterweight 26, which is beneficial to expanding the range of large adjustments of the initial inclination of the wind deflector 14.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
