Description

Technical Field

[0001] The utility model relates to the technical field of heat pumps, in particular to an air source heat pump device. Background Art

[0002] An air source heat pump is a device that absorbs heat from the air to provide heating, cooling, and hot water. Its basic principle is to use a compressor and refrigerant cycle to transfer the low-temperature heat in the outside air to the interior through a heat exchange device. Air source heat pumps have the advantages of energy saving, environmental protection, and low carbon emissions. They are widely used in heating, cooling, and domestic hot water supply in residential, commercial, and industrial fields. Compared with traditional electric and gas heating methods, air source heat pumps can effectively reduce energy consumption and greenhouse gas emissions.

[0003] Since air source heat pumps are generally installed outdoors for use, rainwater often enters their air inlets when it rains. Although drainage systems such as gutters are designed inside the pump to effectively drain the rainwater that enters, the internal components will still be affected by long-term rainwater erosion and soaking, which will affect their service life and cause damage.

[0004] In view of this, we propose an air source heat pump device. Utility Model Content

[0005] In response to the above-mentioned shortcomings of the prior art, the present invention provides an air source heat pump device, which can effectively solve the problem that water will enter the air inlet of the prior art air source heat pump on rainy days, thereby causing damage to internal components and affecting its service life.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides an air source heat pump device, comprising a heat pump body and an air intake hopper fixedly mounted on the top of the heat pump body, wherein a plurality of connecting rods are rotatably mounted on the side wall of the inner cavity of the air intake hopper, a guide plate is rotatably mounted on one end of the plurality of connecting rods away from the air intake hopper, and a vane is fixedly mounted on the other end of the plurality of connecting rods, and an air bag layer is fixedly mounted on the surface of the plurality of vanes;

[0008] Among them, a fixing rod is fixedly installed at one end of one group of blades in the multiple groups of blades, and the end of the fixing rod away from the blade rotates through the air intake hopper, and a driving mechanism is provided at the end of the fixing rod passing through the air intake hopper. The driving mechanism can drive the multiple groups of blades to rotate at the same time, and synchronously inflate and exhaust the airbag layers fixedly installed on the surface of the multiple groups of blades.

[0009] Furthermore, the driving mechanism includes a motor arranged at one end of the fixed rod passing through the air inlet hopper, a bracket is fixedly installed on one side of the motor, and the bottom of the bracket is fixedly installed on the top of the heat pump body.

[0010] Furthermore, one end of the fixing rod passes through the air intake scoop and extends to the interior of the bracket, and the motor is fixedly mounted on the end of the fixing rod extending to the interior of the bracket via the output shaft.

[0011] Furthermore, a telescopic rod is fixedly mounted on the surface of the fixed rod, a push-pull rod is rotatably mounted on one end of the telescopic rod away from the fixed rod, and a sealing piston is fixedly mounted on one end of the push-pull rod away from the telescopic rod.

[0012] Furthermore, a piston cylinder is movably sleeved on the surface of the sealing piston, and the bottom of the piston cylinder is fixedly mounted on the top of the bracket.

[0013] Furthermore, a fixed elbow is fixedly installed on one side of the piston cylinder, an end of the fixed elbow away from the piston cylinder is fixedly passed through the air intake hopper, and an end of the fixed elbow passing through the air intake hopper is fixedly installed on the inner cavity side wall of the air intake hopper.

[0014] Furthermore, a plurality of groups of telescopic hoses are fixedly installed on the surface of the fixed elbow, and the tops of the plurality of groups of telescopic hoses are fixedly installed on the surface of the airbag layer.

[0015] Compared with the known public technologies, the technical solution provided by this utility model has the following beneficial effects:

[0016] The utility model arranges multiple groups of blades in the air intake hopper. When it rains, the multiple groups of blades can be driven by a driving mechanism to flip over and arrange them in a flat manner. During the flipping process of the blades, the air bag layer on the surface of the multiple groups of blades can be inflated, thereby improving the sealing between the multiple groups of blades and the edge of the air intake hopper, avoiding the entry of rainwater and the damage to the internal components, which affects the service life. On the contrary, in normal weather, when air intake is needed, the multiple groups of blades can be rotated in the opposite direction and unfolded by the driving mechanism, and the gas in the air bag layer can be extracted at the same time, so that the air inlet is larger and convenient for air intake.

DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] An air source heat pump device includes a heat pump body 1 and an air inlet hopper 2 fixedly mounted on the top of the heat pump body 1, a plurality of groups of connecting rods 13 are rotatably mounted on the side wall of the inner cavity of the air inlet hopper 2, a guide plate 12 is rotatably mounted on the end of the plurality of groups of connecting rods 13 away from the air inlet hopper 2, a vane 15 is fixedly mounted on the other end of the plurality of groups of connecting rods 13, and an air bag layer 3 is fixedly mounted on the surface of the plurality of groups of vanes 15, wherein a fixing rod 7 is fixedly mounted on one end of one group of vanes 15 in the plurality of groups of vanes 15, an end of the fixing rod 7 away from the vane 15 rotates through the air inlet hopper 2, and a driving mechanism is provided on the end of the fixing rod 7 that passes through the air inlet hopper 2, and the driving mechanism can drive the plurality of groups of vanes 15 to rotate simultaneously, and synchronously inflate and exhaust the air bag layers 3 fixedly mounted on the surfaces of the plurality of groups of vanes 15;

[0027] Specifically, the drive mechanism includes a motor 6 provided at one end of a fixed rod 7 passing through the air inlet scoop 2, a bracket 4 fixedly mounted on one side of the motor 6, the bottom of the bracket 4 fixedly mounted on the top of the heat pump body 1, the fixed rod 7 passing through one end of the air inlet scoop 2 and extending into the interior of the bracket 4, and the motor 6 is fixedly mounted on the end of the fixed rod 7 extending into the interior of the bracket 4 via an output shaft;

[0028] Specifically, the output of the motor 6 in the bracket 4 can drive the fixed rod 7 to rotate, and the fixed rod 7 can be used to rotate a group of blades 15. The connecting rod 13 fixedly installed on one side of the blade 15 can drive the guide plate 12 to move. Therefore, the multiple groups of connecting rods 13 rotatably installed on one side of the guide plate 12 can drive the multiple groups of blades 15 to rotate synchronously. At the same time as the multiple groups of blades 15 rotate, the interior of the multiple groups of airbag layers 3 can be inflated and sucked.

[0029] Furthermore, a telescopic rod 9 is fixedly installed on the surface of the fixed rod 7, and a push-pull rod 10 is rotatably installed on the end of the telescopic rod 9 away from the fixed rod 7. A sealing piston 11 is fixedly installed on the end of the push-pull rod 10 away from the telescopic rod 9. The surface of the sealing piston 11 is movably sleeved with a piston cylinder 5. The bottom of the piston cylinder 5 is fixedly installed on the top of the bracket 4. A fixed elbow 8 is fixedly installed on one side of the piston cylinder 5. The end of the fixed elbow 8 away from the piston cylinder 5 is fixedly passed through the air inlet hopper 2, and the end of the fixed elbow 8 passing through the air inlet hopper 2 is fixedly installed on the side wall of the inner cavity of the air inlet hopper 2. Several groups of telescopic hoses 14 are fixedly installed on the surface of the fixed elbow 8, and the tops of the several groups of telescopic hoses 14 are fixedly installed on the surface of the airbag layer 3;

[0030] Specifically, when the fixed rod 7 rotates, it can drive the telescopic rod 9 fixedly installed on its surface to rotate. Since the sealing piston 11 fixedly installed at one end of the push-pull rod 10 is limited by the piston cylinder 5, the telescopic rod 9 is extended and retracted while the telescopic rod 9 rotates, and the push-pull rod 10 can be pulled back and forth at the same time. The movement of the sealing piston 11 in the piston cylinder 5 can be used to evacuate and inflate the air. Through the fixed elbow 8 and the multiple sets of telescopic hoses 14 fixedly installed on the surface of the fixed elbow 8, the interior of the multiple sets of airbag layers 3 can be inflated and the gas in the airbag layers 3 can be sucked out, thereby ensuring the sealing of the air inlet hopper 2 on rainy days and preventing rainwater from entering the heat pump body 1. At the same time, in normal weather, when normal work is required, the gas in the multiple sets of airbags 3 is extracted and the blades 15 are flipped and unfolded, so that the air inlet becomes larger, thereby effectively improving the air intake efficiency.

[0031] The working principle of the present invention is as follows: when it rains, the output of the motor 6 can be used to drive the fixed rod 7 to rotate, and the fixed rod 7 can be used to rotate a group of blades 15. The connecting rod 13 fixedly installed on one side of the group of blades 15 can drive the guide plate 12 to move, so that the multiple groups of connecting rods 13 rotatably installed on one side of the guide plate 12 can drive the multiple groups of blades 15 to rotate synchronously and arrange them flatly. The fixed rod 7 can also drive the telescopic rod 9 fixed on the surface to rotate. Since the sealing piston 11 fixed on one end of the push-pull rod 10 is limited by the piston cylinder 5, Therefore, when the telescopic rod 9 rotates, its push-pull rod 10 can be pushed to move forward, so that the movement of the sealing piston 11 in the piston cylinder 5 is utilized to inflate. Through the fixed elbow 8 and the multiple sets of telescopic hoses 14 fixedly installed on the surface of the fixed elbow 8, the interior of the multiple airbag layers 3 can be inflated, thereby improving its sealing performance and preventing rainwater from entering. On the contrary, under normal weather conditions, when it is necessary to pass through the air intake hopper 2, the reverse output rotation of the motor 6 can flip open the multiple sets of blades 15, which simultaneously evacuates the air in the airbag layer 3, making the air inlet larger and improving the air intake efficiency.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
