[0002] With the continuous growth of energy demand and the increasing emphasis on energy conservation and environmental protection, air source heat pumps, as devices that can effectively utilize the heat energy in the air for heating or cooling, have been increasingly widely used. However, existing air source heat pump units still have some shortcomings in actual operation. On rainy days, rainwater enters the air source heat pump unit through the exhaust fan at the top, making the equipment inside the unit susceptible to rainwater damage, leading to equipment damage or performance degradation. Therefore, there is an urgent need for air source heat pump units to solve the above problems. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-3 An embodiment of this utility model provides an air source heat pump unit, including an air source heat pump unit body 1 and an exhaust fan 2. Two exhaust fans 2 are provided and are symmetrically fixedly installed at the top of the air source heat pump unit body 1. A rain shield 7 is provided at the top of the exhaust fan 2. A straight cutting plate 10 is provided on one side of the rain shield 7. Two support plates 11 are symmetrically fixedly connected to the top of the side of the rain shield 7 near the straight cutting plate 10. A first support inclined plate 12 is fixedly connected to one side of the bottom of the rain shield 7. A drain pipe 13 is fixedly connected to the bottom of the side of the rain shield 7 near the first support inclined plate 12. Two second support inclined plates 15 are symmetrically fixedly connected to the bottom of the side of the rain shield 7 away from the straight cutting plate 10. A support rod 14 is fixedly connected to one end of the second support inclined plate 15 away from the center of the rain shield 7. A rotating bracket 16 is fixedly connected to the bottom of the two support rods 14.

[0020] The rain shield 7 has a conical design and a water receiving groove at the top. The end of the drain pipe 13 near the rain shield 7 is connected to the bottom of the water receiving groove inside the rain shield 7. Rainwater is received at the top of the rain shield 7 and discharged through the drain pipe 13. The top of the drain pipe 13 is fixedly connected to the bottom of the first support inclined plate 12. The end of the drain pipe 13 away from the rain shield 7 is bent downwards. The top of the support rod 14 is fixedly connected to the bottom of the rain shield 7.

[0021] A rainwater sensor 9 is fixedly installed at the center of the top of one side of the air source heat pump unit body 1. A PLC controller 8 is fixedly installed at the center of the top of the air source heat pump unit body 1, near the rainwater sensor 9. Four mounting plates 3 are symmetrically fixedly connected to the top of the air source heat pump unit body 1. An electric push rod 4 is rotatably installed at the end of the mounting plate 3 away from the center of the air source heat pump unit body 1. Connecting brackets 5 are fixedly installed at both ends of the top of the air source heat pump unit body 1. The four electric push rods 4 are symmetrically distributed at both ends of the two connecting brackets 5. Two support frames 6 are symmetrically fixedly installed at the top center of the pump unit body 1. The support frames 6 support the rain shield 7 and rotate one side of the bracket 16, thereby increasing the stability of the rain shield 7. The PLC controller 8 is wiredly connected to the electric push rod 4 and the rain sensor 9. When it rains, the rain sensor 9 detects the rain and transmits the detection signal to the PLC controller 8. When the PLC controller 8 receives the rain signal, it controls the rain shield function to be turned on. When the rain stops, the rain sensor 9 transmits the signal to the PLC controller 8, and the PLC controller 8 controls the rain shield function to be turned off.

[0022] The bottom end of the rotating bracket 16 is hinged to the top end of the connecting bracket 5. The telescopic end of the electric push rod 4 is rotatably mounted on the bottom end of the rotating bracket 16. The telescopic end of the electric push rod 4 pushes the bottom end of the rotating bracket 16 to move. The movement of the bottom end of the rotating bracket 16 causes the rotating bracket 16 to rotate at the top end of the connecting bracket 5. The bottom end of the support plate 11 and the top end of the support frame 6 are in contact. When the bottom end of the support plate 11 contacts the top end of the support frame 6, the rain shield 7 completely covers the top of the exhaust fan 2. The bottom end of the rotating bracket 16 and the outer end of the connecting bracket 5 are in contact. After the rain stops, the telescopic end of the electric push rod 4 drives the rotating bracket 16 to rotate. The rotation of the rotating bracket 16 causes the rain shield 7 to rotate upward until the bottom end of the rotating bracket 16 is close to the outer end of the connecting bracket 5. At this time, the rain shield 7 is fully open.

[0023] Working Principle: During use, the control program is first set by the PLC controller 8. When it rains, the rain sensor 9 detects rainwater and transmits the signal to the PLC controller 8. After receiving the signal, the PLC controller 8 controls the electric push rod 4 to extend. The extension end of the electric push rod 4 pushes the bottom end of the rotating bracket 16 to move. The movement of the bottom end of the rotating bracket 16 causes the rotating bracket 16 to rotate at the top of the connecting bracket 5. The rotation of the rotating bracket 16 drives the support rod 14 to rotate. The rotation of the support rod 14 drives the rain shield 7 to rotate and simultaneously drives the support plate 11 to rotate. When the rain shield 7 rotates until the bottom end of the support plate 11 contacts the top end of the support frame 6, the PLC controller 8 controls the electric push rod 4 to stop extending. At this time, the rain shield 7 completely covers the top of the exhaust fan 2. Rainwater falls into the interior of the top of the rain shield 7 and is discharged through the drain pipe 13. The air blown upward by the exhaust fan 2 diffuses outward through the conical bottom of the rain shield 7, thus ensuring the smooth flow of the exhaust fan 2. When the rain stops and the water vapor on the top of the rain sensor 9 evaporates, the rain sensor 9 transmits a signal to the PLC controller 8. After receiving the signal, the PLC controller 8 controls the electric push rod 4 to retract. The extension end of the electric push rod 4 drives the rotating bracket 16 to rotate. The rotation of the rotating bracket 16 drives the rain shield 7 to rotate upward until the bottom of the rotating bracket 16 is in close contact with the outer end of the connecting bracket 5. At this time, the two rain shields 7 open in opposite directions and completely detach from the top of the exhaust fan 2.
