DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0015] In the description of the invention, it is necessary to understand that the directions or positional relationships indicated by the terms "front", "rear", "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the invention.

[0016] like Figure 1-6 As shown, this embodiment discloses a solar air source heat pump unit, which mainly includes a heat pump unit body 1 and a solar panel 7. The bottom of the heat source pump unit body 1 is fixedly connected with a moving mechanism 2, the top of the heat source pump unit body 1 is fixedly connected with a mounting mechanism 3, and the rear surface of the heat source pump unit body 1 is fixedly connected with a solar heat exchanger 4.

[0017] In this embodiment, the moving mechanism 2 includes a base 201, a cavity is provided in the base 201, and a through vertical groove 202 is opened on both sides of the base 201. The inner side of the vertical groove 202 is slidably connected with a sliding block 203 that can be lifted up and down. The opposite sides of the two sliding blocks 203 are located on the inner side of the base 201 and are fixedly connected with a lifting plate 204, so that the lifting plate 204 can move up and down. The bottom of the lifting plate 204 is fixedly connected with a plurality of embedded blocks 205. The bottom of the embedded block 205 penetrates the bottom of the base 201 and is rollingly installed with a ball 206. The ball 206 and the embedded block 205 form a roller mechanism. When the lifting plate descends, the roller mechanism can extend out of the bottom surface of the base and contact the ground, thereby realizing the movement of the entire device with the help of the ball 206. The opposite sides of the two sliding blocks 203 are fixedly connected with a connecting plate 207 extending upward, and the upper opposite sides of the upper ends of the connecting plates 207 are rotatably connected with a rotating column 208 through a rotating shaft. The opposite sides of the two rotating columns 208 are fixedly connected to the left and right sides of the solar panel 7 respectively.

[0018] In this embodiment, the mounting mechanism 3 includes a mounting plate 301, the upper surface of which is fixedly connected with a concave connector 5, the inner side of which is rotatably connected with a rotating block 6 via a rotating shaft, the upper surface of which is fixedly connected to the bottom front side of the solar panel 7, so that the rotation connection point between the connecting plate and the solar panel is located behind the rotation connection point between the solar panel and the mounting mechanism. When the solar panel is in a horizontal position, the roller mechanism extends out of the bottom surface of the base and contacts the ground, and when the solar panel is in an inclined position, the roller mechanism retracts into the base. The upper surface of the mounting plate 301 is embedded with a strip box 302 that is horizontally distributed on the left and right sides. The right side of the strip box 302 is rotatably connected to a shaft rod 303 through a rotating shaft. The right end outer wall of the shaft rod 303 is fixedly connected to a gear 304. The left end of the shaft rod 303 is fixedly connected to an exhaust pipe 305. The exhaust pipe can be rotatably installed in the strip box. A plurality of exhaust holes 306 are integrally formed on the front surface of the exhaust pipe 305. The left side of the heat source pump unit body 1 is fixedly connected to a fan 8. The output end of the fan 8 is fixedly connected to a ventilation hose 9. The end of the ventilation hose 9 away from the fan 8 passes through the interior of the strip box 302 and is connected to the left side of the exhaust pipe 305 through a rotating shaft. With such a design, when the exhaust pipe is turned over, the ventilation hose 9 is prevented from rotating, and it is ensured that the ventilation hose can always be connected to the exhaust pipe. In order to realize the flipping of the exhaust pipe without the need for additional electrical components, a linkage groove 307 is provided on the upper surface of the mounting plate 301 on the right side of the rear surface of the strip box 302, a wedge block 308 is slidably connected to the inner side of the linkage groove 307, a rack 309 is fixedly connected to the front surface of the wedge block 308, and a plurality of first springs 310 are fixedly connected between the wedge block 308 and the linkage groove 307, one end of the first spring is connected to the wedge block, and the other end is connected to the front side of the linkage groove. The front end of the rack 309 penetrates into the interior of the strip box 302 and is meshed with the gear 304.

[0019] The right side of the lower surface of the solar panel is fixedly connected with an extrusion block 11 that can be rotatably embedded in the linkage groove. When the solar panel 7 is tilted, the extrusion block 11 will drop and enter the linkage groove to push the wedge block 308 to move forward, thereby driving the rack 309 to move forward so that the gear 304 drives the exhaust pipe 305 to rotate, thereby turning the exhaust hole 306 out from the inside of the strip box 302, so that it can be tilted toward the surface of the solar panel 7. When the fan 8 is started to exhaust air, the exhaust hole 306 will blow air toward the surface of the solar panel 7 to play a dust cleaning role. When the solar panel 7 is horizontal and the device is in the storage state, under the action of the first spring, the rack moves backward, so that the exhaust hole 306 is hidden on the inside of the strip box 302 to avoid the problem of blockage.

[0020] In this embodiment, two blocks 10 are fixedly connected to the front position of the lower surface of the solar panel in a symmetrical manner, and two movable grooves 12 are symmetrically provided on the upper surface of the mounting plate 301. A hollow block 13 is slidably connected inside the movable groove 12, and a piston block 14 is slidably connected inside the hollow block 13. An extension column 15 is fixedly connected to the upper surface of the piston block 14. The top of the extension column 15 passes through the upper surface of the hollow block 13 and is fixedly connected to a connecting block 16. A bayonet 17 is provided on the upper surface of the connecting block 16, and the bayonet 17 can be interlocked with the block 10. A plurality of second springs 18 are fixedly connected between the piston block 14 and the bottom of the hollow block 13. A U-shaped pull rod 19 is provided in front of the mounting plate 301. The two ends of the U-shaped pull rod 19 respectively pass through the inside of the two movable grooves 12 and are fixedly connected to the front surfaces of the two hollow blocks 13. An air bag 20 is sleeved on the outer wall of the U-shaped pull rod 19, and the air bag 20 is connected to the upper position of the hollow block through a ventilation pipe. By pressing the airbag 20, the piston block 14 drives the connecting block 16 to descend, so that the bayonet 17 is disengaged from the outside of the block 10, and then the U-shaped pull rod 19 is pulled forward by hand to make the hollow block 13 slide forward along the inner side of the movable groove 12 and move away from under the solar panel 7, thereby facilitating the tilting of the solar panel 7.

[0021] The specific working process of the solar air source heat pump unit described in this embodiment is as follows: When the block 10 is engaged in the slot 17, the solar panel 7 is horizontal. When the block 10 is disengaged from the slot 17, the lower surface of the solar panel 7 loses its obstruction in front, and the embedded block 205 shrinks into the base 201. At this time, the connecting plate 207 pushes the solar panel 7 to tilt the solar panel 7, so that the solar panel 7 can be tilted toward the sunlight exposure position, and the device is not easy to move.

[0022] The working principle of this device is: When the device is not in working state, the block 10 will be engaged with the inner side of the bayonet 17, and at this time, it will press against the front of the lower surface of the solar panel 7, so that the solar panel 7 is in a horizontal state. At this time, the connecting plate 207 is squeezed downward, so that the sliding block 203 is at the bottom of the vertical groove 202, and the embedded block 205 extends out of the bottom of the base 201. The ball 206 contacts the ground. The moving mechanism 2 can realize the movement of the entire device through the set ball 206. Since the solar panel is in a horizontal storage state, it is convenient to move the device; at the same time, the multiple exhaust holes 306 on the outer wall of the exhaust pipe 305 are blocked on the inner side of the strip box 302 to avoid clogging by dust; When the device is moved to the installation position for use, by pressing the airbag 20, the air pressure causes the piston block 14 to drive the connecting block 16 to descend, so that the bayonet 17 is disengaged from the outside of the block 10, and then the U-shaped pull rod 19 is held and pulled forward, so that the hollow block 13 slides forward along the inner side of the movable groove 12 and moves away from under the solar panel 7. At this time, the front half of the lower surface of the solar panel 7 loses its abutment, and due to the sliding connection between the vertical groove 202 and the sliding block 203, the base of the device descends under the weight of the device itself, so that the lifting plate 204 drives the ball 206 to relatively shrink to the inside of the base 201, thereby pushing the connecting plate 207 to rise together, and the top of the connecting plate 207 will lift the rear of the solar panel 7, so that the solar panel 7 is tilted and in a working state. At this time, the device as a whole is not easy to move and can be used at a fixed point. At the same time, the squeezing block 11 will squeeze the wedge block 308 to move during the downward movement, driving the exhaust tube 305 to rotate, so that the exhaust hole 306 can be tilted toward the surface of the solar panel 7, so that when the fan 8 is started to exhaust air, the exhaust hole 306 will blow air toward the surface of the solar panel 7 to play a role in cleaning dust; When the device is not in use, the airbag 20 is pressed, the piston block 14 drives the connecting block 16 to descend, and the handheld U-shaped pull rod 19 is pushed backward, and the solar panel 7 is manually lifted to a horizontal state. After the solar panel 7 is horizontal, it will push the connecting plate 207 to pull the lifting plate 204 down, and at this time, the ball 206 will extend from the bottom of the base 201 again, which is convenient for moving the position; when the connecting block moves to the bottom of the card block 10, the airbag is released, and under the action of the second spring, the connecting block rises, so that the bayonet 17 is engaged with the outside of the card block 10, thereby supporting the solar panel 7. Through the design of this device, the roller mechanism and the solar panel on the top are integrally linked through the lifting plate and the connecting plate. When the solar panel is in a horizontal position, the roller mechanism extends out of the bottom surface of the base and contacts the ground, which is convenient for carrying the heat pump unit. When the solar panel is in an inclined position, the roller mechanism shrinks into the base, so that the solar panel can be tilted toward the sunlight exposure position, and the whole is not easy to move; the structure is compact, the volume is small, and the use is flexible.
