Description

Technical Field

[0001] This utility model belongs to the technical field of air source heat pump units, and specifically relates to a photovoltaic direct-drive air source heat pump unit. Background Technology

[0002] Photovoltaic direct-drive heat pumps utilize the electricity generated by photovoltaic modules to drive the heat pump unit, providing users with hot or cold water. This method effectively combines the consumption of photovoltaic power with efficient heat generation. Heat pumps offer heating, cooling, and dehumidification functions. In agricultural production, they can regulate the growing environment, such as in agricultural greenhouses and livestock pens, where air-source and ground-source heat pumps can control temperature and humidity. In aquaculture, heat pumps regulate temperature, ensuring aquatic products live in suitable water temperatures, promoting growth and development, increasing survival rates, and reducing disease incidence, thereby improving both yield and quality. In sea cucumber farming, suitable temperatures can double yields, resulting in significant economic benefits. In agricultural processing, heat pumps can be used for drying timber, food, grains, fruits, vegetables, and tobacco; they can also provide the hot water needed for slaughtering and processing.

[0003] In existing technologies, photovoltaic direct-drive heat pump units are typically installed on rooftops with ample sunlight (such as factory buildings). The photovoltaic panels absorb solar energy through brackets, while the direct-drive heat pump unit is installed on the ground or rooftop platform nearby through brackets. The two are connected by short-path DC cables and insulated refrigerant pipes to form a compact system of "photovoltaic power generation - direct-drive heat pump - end-point energy consumption".

[0004] However, existing photovoltaic direct-drive air source heat pump units have drawbacks. Because existing photovoltaic panels and heat pump units are mostly installed separately, photovoltaic panels need to be installed using independent brackets. During installation, the photovoltaic panels can achieve the best solar radiation reception efficiency through the tilt angle design of the brackets. Therefore, a distance needs to be left between the photovoltaic panels and the ground, which results in the space under the brackets being a blank area. This forces the three-dimensional space under the brackets to be idle, forming a large gap and seriously reducing the space utilization rate of the factory roof. Utility Model Content

[0005] In response to the problem that the three-dimensional space under the photovoltaic panel support is forcibly left idle in related technologies, reducing the space utilization rate of factory roofs, this utility model proposes a photovoltaic direct-drive air source heat pump unit to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a photovoltaic direct-drive air source heat pump unit, including a mounting frame. The mounting frame is provided with a locking and clamping mechanism, and the heat pump unit body is provided inside the locking and clamping mechanism. A compression lifting mechanism is provided on one side of the mounting frame. An angle adjustment mechanism is provided at the lifting end of the compression lifting mechanism. A synchronous folding mechanism is provided at the adjustment end of the angle adjustment mechanism. A photovoltaic panel body is provided at the folding end of the synchronous folding mechanism.

[0008] By rotating the synchronous end of the synchronous folding mechanism, the synchronous end drives the folding end of the synchronous folding mechanism to unfold or close, thereby causing the photovoltaic panel body to open and close synchronously within the folding end of the synchronous folding mechanism.

[0009] Furthermore, the extrusion lifting mechanism includes a lifting plate, which is slidably connected inside the mounting frame. A lifting rod is rotatably connected to the bottom of the lifting plate. A movable plate is rotatably connected to one end of the lifting rod, and a lifting rod is rotatably connected to one end of the movable plate. One end of the lifting rod is rotatably connected inside the mounting frame.

[0010] Furthermore, a control plate is slidably connected inside the mounting bracket, and a bidirectional screw is rotatably connected inside the control plate. The surface of the bidirectional screw is threadedly connected to a movable plate, and the movable plate is slidably connected inside the control plate. A toggle ring is fixedly connected to the middle of the bidirectional screw.

[0011] Furthermore, the angle adjustment mechanism includes an adjustment disc, which is rotatably connected inside the lifting plate. One end of the adjustment disc is fixedly connected to a support frame. A rack is slidably connected inside the lifting plate, and the surface of the rack meshes with the adjustment disc. An adjustment bolt is rotatably connected inside the lifting plate, and the surface of the adjustment bolt is threadedly connected to the rack.

[0012] Furthermore, the synchronous folding mechanism includes two unfolding frames, both of which are slidably connected inside the support frame. Photovoltaic panel bodies are fixedly installed inside both the support frame and the unfolding frames. Several toothed grooves are formed on the surface of the unfolding frames, and gear shafts are meshed on the surface of the toothed grooves. The gear shafts are rotatably connected inside the support frame.

[0013] Furthermore, a timing pulley is fixedly connected to one end of the gear shaft, a timing belt meshes on the surface of the timing pulley, a timing pulley is meshed inside the timing belt, a handle is fixedly connected to one end of the timing pulley, the timing pulley is rotatably connected to one side of the support frame, and several limiting wheels are rotatably connected to one side of the support frame, with the surfaces of the several limiting wheels contacting the surface of the timing belt.

[0014] Furthermore, the locking and clamping mechanism includes a mounting plate, which is slidably connected inside the mounting frame. The mounting frame has several locking grooves on its surface. Several rollers are fixedly installed below the heat pump unit body. The rollers engage with the locking grooves. Two lever plates are rotatably connected to the surface of the mounting frame. A locking block is fixedly connected to one end of each lever plate. One side of the locking block engages with one side of the roller. Tension springs are fixedly connected to the surfaces of both lever plates. Support legs are fixedly installed on one side of each mounting frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses the clamping end of the clamping mechanism to fix the heat pump unit body inside the mounting frame. By rotating the synchronous end of the synchronous folding mechanism, the synchronous end drives the folding end of the synchronous folding mechanism to open or close, thereby allowing the photovoltaic panel body to open and close synchronously within the folding end of the synchronous folding mechanism. This design, through an integrated installation structure, realizes the integrated support of the heat pump unit body and the photovoltaic panel body on a single bracket, making full use of the space under the photovoltaic panel body and significantly improving the space utilization efficiency of the factory roof.

[0017] 2. This utility model allows the mounting plate to slide out and touch the ground, forming an angled ramp with the mounting frame. The heat pump unit body slides into the mounting frame along the ramp via rollers. When the rollers press against the lever plate, the tension spring maintains the angled state of the lever plate to ensure interference-free sliding. The moment the rollers fully enter the locking groove, the lever plate drives the locking block to rigidly lock the side edge of the rollers, completing the self-locking fixation. This design, through the installation ramp and self-locking mechanism, reduces the phenomenon of the top of the heat pump unit body hitting the photovoltaic panel body caused by lifting during traditional installation of the heat pump unit body. At the same time, through the three-stage linkage of sliding-avoidance-locking, it realizes the rapid installation of heavy equipment.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-6As shown, this utility model is a photovoltaic direct-drive air source heat pump unit, including a mounting frame 1, a locking and clamping mechanism 7 is provided inside the mounting frame 1, a heat pump unit body 2 is provided inside the locking and clamping mechanism 7, a squeezing and lifting mechanism 3 is provided on one side of the mounting frame 1, an angle adjustment mechanism 4 is provided at the lifting end of the squeezing and lifting mechanism 3, a synchronous folding mechanism 5 is provided at the adjustment end of the angle adjustment mechanism 4, and a photovoltaic panel body 6 is provided at the folding end of the synchronous folding mechanism 5.

[0031] By rotating the synchronous end of the synchronous folding mechanism 5, the synchronous end drives the folding end of the synchronous folding mechanism 5 to unfold or close, thereby causing the photovoltaic panel body 6 to open and close synchronously within the folding end of the synchronous folding mechanism 5.

[0032] The heat pump unit body 2 is fixed inside the mounting frame 1 by the clamping mechanism 7. The rotating pressing lifting mechanism 3 drives the angle adjustment mechanism 4 to lift and lower. The angle adjustment mechanism 4 adjusts the angle of the photovoltaic panel body 6 installed on the surface of the synchronous folding mechanism 5. Then, the synchronous folding mechanism 5 is rotated to unfold the photovoltaic panel body 6 inside the synchronous folding mechanism 5. By combining and installing the photovoltaic panel body 6 with the heat pump unit body 2, the space below the photovoltaic panel body 2 is fully utilized, reducing the area occupied.

[0033] The heat pump unit body 2 is fixed inside the mounting frame 1 by the clamping end of the clamping mechanism 7. The synchronous end of the synchronous folding mechanism 5 is rotated so that its synchronous end drives the folding end of the synchronous folding mechanism 5 to open or close, thereby making the photovoltaic panel body 6 open and close synchronously within the folding end of the synchronous folding mechanism 5. This design, through an integrated installation structure, realizes the integrated support of the heat pump unit body 2 and the photovoltaic panel body 6 by a single bracket, so that the space under the photovoltaic panel body 2 is fully utilized, significantly improving the space utilization efficiency of the factory roof.

[0034] Furthermore, in practical applications, the heat pump unit 2 and the air conditioner operate on the same principle, both belonging to the Carnot cycle or reverse Carnot cycle process. Heating and cooling can be achieved by switching via a four-way valve. The basic principle of the heat pump unit 2 is the reverse Carnot cycle. The high-temperature, high-pressure gaseous working fluid discharged from the compressor enters the condenser to release heat and is condensed into a liquid working fluid. The liquid working fluid is depressurized by a throttling device and enters the evaporator, where it evaporates and absorbs heat from a low-temperature heat source. The low-temperature, low-pressure gaseous working fluid is then drawn into the compressor and compressed to form a high-temperature, high-pressure gaseous working fluid, which then enters the condenser to release heat, completing one cycle. The working fluid in the condenser is heated by the high-temperature, high-pressure gaseous working fluid, gaining heat and increasing its temperature, which can then be supplied to the end-user for heating. The hot water produced by the heat pump unit 2 can be used for domestic hot water, heating, and industrial and agricultural heating. By switching via the four-way valve, the heat pump unit 2 can also produce cold water for cooling or temperature reduction. Currently, air source heat pumps are the most widely used type of heat pump. They employ a full DC inverter compressor and fan, as well as jet enthalpy enhancement or liquid injection enthalpy enhancement technology. This not only improves the energy efficiency of the heat pump unit but also allows the heat pump to heat normally under low ambient temperature conditions. Full DC inverter technology is a commonly used method for air source heat pumps. Its control principle is as follows: the unit is powered by AC power, which is rectified and filtered into DC power, and then inverted into variable frequency AC power to drive the compressor and motor.

[0035] Due to the discontinuous and unstable nature of solar energy, photovoltaic direct-drive heat pumps need to ensure stable heating in aspects such as photovoltaic system MPPT control, photovoltaic-mains power supply coordination, and load and drive control. Among these, the dynamic matching mechanism between photovoltaic power generation and heat pump load is crucial. The output power of photovoltaic cells is affected by light intensity and temperature, exhibiting nonlinear changes. During operation, the heat pump unit adjusts the compressor and fan speeds and the opening of the electronic expansion valve in real time according to the power demand of the end-user energy consumption, based on ambient temperature, evaporation / condensation temperature, etc. The dynamic matching mechanism between photovoltaic power generation and heat pump load needs to be studied to achieve real-time coordination between photovoltaic output power and the power demand of the heat pump compressor.

[0036] The DC power from the photovoltaic panel 6 is filtered and boosted before being supplied to the DC bus, entering the IPM inverter module. This IPM module dynamically matches the compressor's output to power the compressor and fan (the compressor requires stable output under full load or non-full load conditions). The AC power (single-phase or three-phase) is rectified and filtered before also being supplied to the DC bus and entering the IPM module. When the heat pump unit requires full load output and photovoltaic power is insufficient, both the photovoltaic modules supply power to the compressor and motor, or the photovoltaic modules supply power to the compressor and fan independently (when there is no photovoltaic output). Under this power supply topology, the photovoltaic direct-drive heat pump unit will operate in the following drive modes: Photovoltaic direct-drive mode: When sunlight is sufficient, the photovoltaic modules output DC power through maximum power point tracking (MPPT) technology. After boosting and filtering, this DC power is directly connected to the DC bus, and the IPM inverter module dynamically matches the power requirements of the compressor and fan. The photovoltaic power completely covers the heat pump load, and the compressor operates in inverter mode without the need for mains power. This mode is suitable for sunny days or environments with strong sunlight, where the photovoltaic module power meets the full-load requirements of the heat pump. Low-power buffer mode: When photovoltaic power generation is lower than the heat pump's base power consumption and the demand for hot / cold water is low, the system actively reduces the compressor's operating frequency, limiting the output power to around the rated value, and slowly heats / cools based on the remaining photovoltaic power through intermittent start-stop or low-speed continuous operation. The IPM module prioritizes photovoltaic power to drive the compressor, while dynamically adjusting the bus voltage to an inefficient but stable range. This mode is suitable for periods of weak sunlight and when user heat demand is low. DC / AC hybrid drive mode: When photovoltaic power generation is insufficient (e.g., on cloudy days or in the evening), the system intelligently switches between the two power input ports, simultaneously utilizing both photovoltaic DC power and rectified DC power from the mains. The IPM module dynamically allocates the input ratio of the two power sources, prioritizing photovoltaic power, with the remaining portion automatically compensated by the mains power. This mode is suitable for scenarios with fluctuating or partially shaded light (such as cloudy weather), where the photovoltaic power is lower than the heat pump's requirements. Under conditions without light (such as at night or in extreme weather), the system is powered entirely by the mains power after rectification and filtering, with the DC bus voltage stabilized at a preset level. The IPM module drives the compressor to operate at full load in inverter mode.

[0037] In one embodiment, the extrusion lifting mechanism 3 includes a lifting plate 301, which is slidably connected inside the mounting frame 1. A lifting rod 302 is rotatably connected to the bottom of the lifting plate 301. A moving plate 303 is rotatably connected to one end of the lifting rod 302. A lifting rod 304 is rotatably connected to one end of the moving plate 303. One end of the lifting rod 304 is rotatably connected inside the mounting frame 1. A control plate 305 is slidably connected inside the mounting frame 1. A bidirectional screw 306 is rotatably connected inside the control plate 305. The surface of the bidirectional screw 306 is threadedly connected to the moving plate 303. The moving plate 303 is slidably connected inside the control plate 305. A toggle ring 307 is fixedly connected to the middle of the bidirectional screw 306.

[0038] By rotating the actuating ring 307, the actuating ring 307 drives the bidirectional screw 306 to rotate, causing the bidirectional screw 306 to drive the moving plate 303 to slide inside the control plate 305. The moving plate 303 drives the lifting rod 1 302 to open and close at the bottom of the lifting plate 301, and at the same time drives the lifting rod 2 304 to open and close inside the mounting frame 1. The control plate 305 slides inside the mounting frame 1, and the lifting rod 1 302 drives the lifting plate 301 to rise and fall inside the mounting frame 1. When the distance between the moving plates 303 is large, it will lift the lifting plate 301. When the distance between the moving plates 303 is small, it will drive the lifting plate 301 to fall.

[0039] In one embodiment, the angle adjustment mechanism 4 includes an adjustment disk 401, which is rotatably connected inside the lifting plate 301. One end of the adjustment disk 401 is fixedly connected to a support frame 402. A rack 403 is slidably connected inside the lifting plate 301, and the surface of the rack 403 meshes with the adjustment disk 401. An adjustment bolt 404 is rotatably connected inside the lifting plate 301, and the surface of the adjustment bolt 404 is threadedly connected to the rack 403.

[0040] By rotating the adjusting bolt 404, the adjusting bolt 404 causes the rack 403 to slide inside the lifting plate 301, which in turn causes the rack 403 to rotate the adjusting plate 401, which in turn causes the adjusting plate 401 to rotate the support frame 402, thus completing the angle adjustment of the support frame 402.

[0041] In one embodiment, the synchronous folding mechanism 5 includes two unfolding frames 501, both of which are slidably connected inside the support frame 402. Photovoltaic panel bodies 6 are fixedly installed inside both the support frame 402 and the unfolding frames 501. The surface of the unfolding frame 501 is provided with a plurality of toothed grooves 502, and a gear shaft 503 is meshed on the surface of the toothed grooves 502. The gear shaft 503 is rotatably connected inside the support frame 402. One end of the gear shaft 503 is fixedly connected to a first synchronous wheel 504. The surface of the first synchronous wheel 504 is meshed with a synchronous belt 505. The inside of the synchronous belt 505 is meshed with a second synchronous wheel 506. One end of the second synchronous wheel 506 is fixedly connected to a handle 507. The second synchronous wheel 506 is rotatably connected to one side of the support frame 402. A plurality of limiting wheels 508 are rotatably connected to one side of the support frame 402. The surfaces of the plurality of limiting wheels 508 contact the surface of the synchronous belt 505.

[0042] By rotating the handle 507, the handle 507 drives the second synchronous pulley 506 to rotate, and the second synchronous pulley 506 drives the synchronous belt 505 to rotate, which in turn drives the first synchronous pulley 504 to rotate. This causes the first synchronous pulley 504 to drive the gear shaft 503 to rotate, and the gear shaft 503 drives the unfolding frame 501 to move through the tooth groove 502. This causes the unfolding frame 501 to slide out from inside the support frame 402, thereby causing the photovoltaic panel body 6 to slide out and complete the unfolding of the photovoltaic panel body 6. The limiting wheel 508 limits the synchronous belt 505, so that the synchronous belt 505 is always engaged with the second synchronous pulley 506.

[0043] In one embodiment, the aforementioned locking and clamping mechanism 7 includes a mounting plate 701, which is slidably connected inside the mounting frame 1. The mounting frame 1 has several locking grooves 702 on its surface. Several rollers 703 are fixedly installed below the heat pump unit body 2. The rollers 703 engage with the locking grooves 702. Two lever plates 704 are rotatably connected to the surface of the mounting frame 1. One end of the lever plate 704 is fixedly connected to a locking block 705. One side of the locking block 705 engages with one side of the roller 703. Tension springs 706 are fixedly connected to the surfaces of both lever plates 704. Support legs 707 are fixedly installed on one side of the mounting frame 1.

[0044] By removing the support leg 707 and then sliding the mounting plate 701 out of the mounting bracket 1, with one side of the mounting plate 701 contacting the ground, the mounting plate 701 and the mounting bracket 1 form an angled ramp. The heat pump unit body 2 slides onto the surface of the mounting plate 701 via several rollers 703, and then onto the surface of the mounting bracket 1. When the rollers 703 pass over the surface of the mounting bracket 1, the sides of the rollers 703 press against two lever plates 704. The two lever plates 704, driven by the tension spring 706, are inclined... The angle will not jam the roller 703, allowing the two lever plates 704 to rotate. When several rollers 703 are engaged in the engagement groove 702, the two lever plates 704 drive the locking block 705 to engage one side of the roller 703, limiting the roller 703 and ensuring the fixation of the heat pump unit body 2. Then, the mounting plate 701 is slid into the mounting frame 1, and finally the support leg 707 is fixed to the side of the mounting frame 1 and then connected and fixed to the ground; this facilitates the installation of the heat pump unit body 2.

[0045] Through the above technical solution, 1. By fixing the heat pump unit body 2 inside the mounting frame 1, by rotating the handle 507, the handle 507 drives the synchronous wheel 506 to rotate, and the synchronous wheel 506 drives the synchronous belt 505 to rotate, which in turn drives the synchronous wheel 504 to rotate. This causes the synchronous wheel 504 to drive the gear shaft 503 to rotate, and the gear shaft 503 drives the unfolding frame 501 to move through the tooth groove 502. This causes the unfolding frame 501 to slide from inside the support frame 402, thereby causing the photovoltaic panel body 6 to slide out and complete the unfolding of the photovoltaic panel body 6. This design, through an integrated installation structure, realizes the integrated support of the heat pump unit body 2 and the photovoltaic panel body 6 on a single bracket, making full use of the space under the photovoltaic panel body 2 and significantly improving the space utilization efficiency of the factory roof.

[0046] 2. By removing the support leg 707, the mounting plate 701 is slid out of the mounting bracket 1, with one side of the mounting plate 701 contacting the ground, forming an angled ramp between the mounting plate 701 and the mounting bracket 1. The heat pump unit body 2 slides onto the surface of the mounting plate 701 via several rollers 703, and then onto the surface of the mounting bracket 1. When the rollers 703 pass over the surface of the mounting bracket 1, their sides press against the two lever plates 704. Under the action of the tension spring 706, the two lever plates 704 are at an angle, preventing them from getting stuck. Rollers 703 cause two lever plates 704 to rotate. When several rollers 703 are engaged in the engagement groove 702, the two lever plates 704 drive one side of the locking block 705 to engage one side of the roller 703, limiting the roller 703 and ensuring the fixation of the heat pump unit body 2. Then, the mounting plate 701 is slid into the mounting frame 1, and finally the support leg 707 is fixed to the side of the mounting frame 1 and then connected and fixed to the ground. This design achieves convenient installation of the heat pump unit body 2 through the installation ramp and self-locking mechanism.
