Description

Technical Field

[0001] The present invention belongs to the technical field of solar energy heat storage, and particularly relates to a solar energy heat storage device for greenhouse greenhouses. Background Art

[0002] Solar energy heat storage technology realizes the collection of solar energy heat with the help of special solar collectors, and relies on heat storage media to complete heat storage. Its core architecture includes solar collectors and heat storage systems. As the core component of the solar energy heat storage system, the solar collector undertakes the key mission of capturing solar radiation and converting it into heat energy. According to different heat collection principles and structures, solar collectors can be divided into various categories such as flat plate type and vacuum tube type. Among them, flat plate collectors, with their simple structure and low cost, have been widely and commonly used in the field of low-temperature heat storage.

[0003] In existing technical practices, most solar collectors adopt a fixed installation mode. Although this installation method is convenient to operate, due to the large area of the solar collector itself, it will inevitably block part of the house after installation, not only destroying the overall beauty of the house, but also bringing many inconveniences to the cleaning work of the house. In addition, to improve the absorption efficiency of solar energy, the solar collector needs to adjust the angle in a timely manner to ensure that it can accurately face the sun, but the existing fixed installation method obviously cannot meet this requirement.

[0015] (3) When the solar collectors of the two photovoltaic modules of the present invention pass through the rotating plate at the same time, the two push rods apply thrust to both ends of the rotating plate at the same time. The solar collector will not rotate around the rotating column, but will cause the two movable roof plates on this side to move downward along the fixed roof plate, and the two movable roof plates on the other side will also move downward along the corresponding fixed roof plate, making the roof of the greenhouse open-air and the sunlight directly irradiate into the greenhouse.

Specific embodiments

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] Embodiment 1: Please refer to Figures 1 - 3 As shown, the present invention provides the following technical solutions: A solar heat storage device for a greenhouse, comprising a greenhouse 1, two groups of photovoltaic modules are provided on the greenhouse 1, the photovoltaic modules include guide grooves 2 laid along the edge of the cross-section of the greenhouse 1, two round rods 3 are provided on the side surface of the guide groove 2, a sliding plate 4 is slidably provided in the middle of the round rods 3, a sliding column 5 is provided at one end of the round rod 3, the sliding column 5 forms a sliding fit with the guide groove 2, the other ends of the round rods 3 are commonly connected to a solar collector 6, a first spring 7 is sleeved outside the round rod 3, and both ends of the first spring 7 are respectively connected to the sliding plate 4 and the solar collector 6; a motor 8 is provided on the sliding plate 4, a friction roller 9 is provided on the rotating shaft of the motor 8, and the friction roller 9 forms a friction fit with the outer side surface of the guide groove 2.

[0029] Working principle of this embodiment: Since spring 1 provides elastic force, the skateboard 4 is always pressed against the guide groove 2, so the friction roller 9 is always in close contact with the side surface of the guide groove 2. The motor 8 provides power to drive the friction roller 9 to rotate. The friction roller 9 rolls on the side surface of the guide groove 2, so that the two sliding columns 5 slide on the guide groove 2 at the same time, so that the round rod 3 and the solar collector 6 move along the guide groove 2. The solar collector 6 can move on the roof and side walls of the greenhouse 1, and the position of the solar collector 6 can be adjusted according to the needs of the user. At the same time, the position of the solar collector 6 can also be adjusted according to the position of the sunlight, that is, the angle of the solar collector 6 can be adjusted so that the solar collector 6 faces the sunlight directly, and the efficiency of the solar collector 6 absorbing sunlight can be adjusted.

[0030] Embodiment 2: On the basis of the specific Embodiment 1, the difference in this embodiment is as follows: Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown in, the photovoltaic module includes two guide rods 10 fixedly arranged on the side surface of the greenhouse 1. A vertical plate 11 is slidably arranged on the two guide rods 10 together. A second spring 12 is sleeved outside the guide rod 10. The two ends of the second spring 12 are respectively connected to the greenhouse 1 and the vertical plate 11. A wiping strip 13 is arranged on one side of the vertical plate 11 close to the solar collector 6. A nozzle seat 14 for cleaning the solar collector 6 is arranged below the vertical plate 11.

[0031] Specifically, the nozzle seat 14 is connected to a water source. When the solar collector 6 moves from bottom to top, the nozzle seat 14 sprays clear water to clean the surface of the solar collector 6, and the wiping strip 13 contacts the surface of the solar collector 6 to dry the solar collector 6. When the solar collector 6 moves from top to bottom, the wiping strip 13 does not contact the solar collector 6.

[0032] Side plates 15 are arranged below both ends of the vertical plate 11. Grooved plates 16 are arranged on the opposite surfaces of the two side plates 15. A groove is arranged in the middle of the grooved plate 16. The groove of the grooved plate 16 is successively composed of an upper inclined groove 1601, a vertical groove 1602 and a lower inclined groove 1603 from top to bottom, and an inclined surface 1604 is arranged on the upper plane of the grooved plate 16.

[0033] A rotating seat 17 is fixedly arranged on the inner side of the solar collector 6. A connecting plate 18 is rotatably arranged on the rotating seat 17. A sliding shaft 19 for engaging with the groove of the grooved plate 16 is arranged at the end of the connecting plate 18. A retaining piece 22 is arranged on the other side of the connecting plate 18 where the sliding shaft 19 is located. A fixed roof plate 23 for blocking the retaining piece 22 is arranged on the rotating seat 17. A spring shaft 20 is arranged between the connecting plate 18 and the solar collector 6. The two ends of the spring shaft 20 are respectively hinged to the connecting plate 18 and the solar collector 6.

[0034] Working principle of this embodiment: In the original state, there is a gap between the solar collector 6 and the wiping strip 13. The spring shaft 20 is in an extended state. The baffle 22 contacts the stop rod 21 to prevent the connecting plate 18 from rotating counterclockwise. The motor 8 provides driving force. According to the principle of the above embodiment, the solar collector 6 moves up and down on the side of the greenhouse 1. When the solar collector 6 moves downward from top to bottom, the sliding shaft 19 contacts the inclined surface 1604, driving the connecting plate 18 to rotate clockwise around the swivel base 17. The spring shaft 20 contracts, and the sliding shaft 19 moves outward along the outside of the groove plate 16. Since the elastic force of the spring shaft 20 is small, the acting force of the sliding shaft 19 on the groove plate 16 is small. Therefore, the vertical plate 11 above the side plate 15 does not slide on the guide rod 10, and there is always a gap between the wiping strip 13 and the solar collector 6, avoiding scratching the solar collector 6 by the wiping strip 13 due to the presence of sediment on the surface of the solar collector 6. When the solar collector 6 moves upward from bottom to top, the nozzle seat 14 sprays clean water on the surface of the solar collector 6 to clean the sediment on the surface of the solar collector 6. At the same time, the sliding shaft 19 aligns with the lower opening of the lower inclined groove 1603, and the sliding shaft 19 enters the groove of the groove plate 16 from the lower opening of the lower inclined groove 1603. Since the connecting plate 18 cannot rotate counterclockwise, the sliding shaft 19 drives the groove plate 16 to move towards the greenhouse 1, making the wiping strip 13 contact the solar collector 6. When the sliding shaft 19 slides in the vertical groove 1602, the wiping strip 13 always contacts the solar collector 6 to dry the surface of the solar collector 6. After the wiping strip 13 is separated from the solar collector 6, the sliding shaft 19 also disengages from the groove of the groove plate 16 from the upper opening of the upper inclined groove 1601.

[0035] Embodiment 3: On the basis of the specific Embodiment 2, the difference in this embodiment is that: Please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown in, on the basis of Embodiment 2, the top of the greenhouse 1 is triangular. Fixed roof plates 23 are provided at the bottoms of both sides of the top of the greenhouse 1. Two movable roof plates 24 are slidably provided side by side on the fixed roof plates 23. A cross-connecting plate 25 is connected between the upper surfaces of the two movable roof plates 24 on one of the fixed roof plates 23. A rotating column 27 is vertically provided at the middle of the upper surface of the cross-connecting plate 25. A rotating plate 26 is rotatably provided at the top of the rotating column 27. A first torsion spring 28 is sleeved outside the rotating column 27. The two ends of the first torsion spring 28 are respectively connected to the cross-connecting plate 25 and the rotating plate 26.

[0036] Specifically, when one end of the rotating plate 26 is stressed, the rotating plate 26 rotates on the rotating column 27, and the first torsion spring 28 stores energy, while the two lower movable roof plates 24 do not move. When thrusts are applied to both ends of the rotating plate 26 at the same time, the rotating plate 26 will not rotate around the rotating column 27, but will cause the two movable roof plates 24 to move downward along the fixed roof plates 23, making the roof of the greenhouse 1 become open-air At the bottom of the solar collector 6, there is a push rod 29 for driving the rotating plate 26. When the solar collectors 6 of the two photovoltaic modules pass through the rotating plate 26, the two push rods 29 simultaneously apply thrust to both ends of the rotating plate 26. When the solar collector 6 of a group of photovoltaic modules passes through the rotating plate 26, one push rod 29 applies thrust to one end of the rotating plate 26.

[0037] Below the movable roof plate 24, there are racks 30. The racks 30 are slidably arranged on the chutes 31. Below the chutes 31, there are first gears 32 meshed with them. The two first gears 32 on each side are fixedly arranged on the first rotating shafts 33. The first rotating shafts 33 are rotatably arranged below the corresponding fixed roof plates 23. Below the two first gears 32 on one side, there are second gears 34 meshed with them respectively. The two second gears 34 are fixedly arranged on the second rotating shaft 35. The second rotating shaft 35 is rotatably arranged below the corresponding fixed roof plate 23. Between the two first gears 32 on the other side, a transmission mechanism 36 is connected between the first rotating shaft 33 and the second rotating shaft 35. The two rotating wheels of the transmission mechanism 36 are respectively arranged on the first rotating shaft 33 and the second rotating shaft 35.

[0038] The transmission mechanism 36 is composed of two transmission wheels and a transmission belt. The two transmission wheels are installed on the transmission belt. When one transmission wheel rotates, power is transmitted through the transmission belt to make the other transmission wheel rotate synchronously.

[0039] Specifically, when the two movable roof plates 24 below the rotating plate 26 move downward along the fixed roof plate 23, their racks 30 slide synchronously in the chutes 31, and then power is transmitted through the corresponding chutes 31 to make the corresponding first rotating shafts 33 rotate synchronously. Then, power is transmitted through the transmission mechanism 36 to make the second rotating shaft 35 rotate synchronously. According to the reverse process of the above principle, the two movable roof plates 24 on the other side also move downward along the fixed roof plate 23, turning the roof of the greenhouse 1 into an open-air state.

[0040] The working principle of this embodiment: When it is not necessary to change the roof of the greenhouse 1, each group of photovoltaic modules is operated separately each time to ensure that only the solar collector 6 of one photovoltaic module passes through the rotating plate 26. When the corresponding push rod 29 passes through the rotating plate 26, the rotating plate 26 rotates, and the first torsion spring 28 stores energy. After the push rod 29 leaves the rotating plate 26, the first torsion spring 28 drives the rotating plate 26 to return to its original rotation state. When it is necessary to turn the roof of the greenhouse 1 into an open-air state, the solar collectors 6 of the two photovoltaic modules are simultaneously made to pass through the rotating plate 26. The two push rods 29 simultaneously apply thrust to both ends of the rotating plate 26. The solar collector 6 will not rotate around the rotating column 27, but will cause the two movable roof plates 24 on this side to move downward along the fixed roof plate 23. According to the above principle, the two movable roof plates 24 on the other side will also move downward along the corresponding fixed roof plate 23, turning the roof of the greenhouse 1 into an open-air state, and sunlight directly irradiates into the interior of the greenhouse 1.

[0041] Embodiment 4: Based on the specific Embodiment 3, the difference in this embodiment is as follows: Please refer to Figure 1 , Figure 2 and Figure 9 As shown, on the other side of the guide rod 10 on the greenhouse 1, there is a storage box 37. The bottom of the storage box 37 is hinged to the middle part of the lever 38. A cover 40 is hinged at the edge of the upper opening of the storage box 37. A second torsion spring 41 is sleeved on the rotating shaft of the cover 40. The two ends of the second torsion spring 41 are respectively connected to the storage box 37 and the cover 40. The upper and lower ends of the connecting rod 39 are respectively hinged to the outer end of the lever 38 and the cover 40.

[0042] Working principle of this embodiment: When the environment becomes harsh, it is necessary to protect the solar collector 6. When the solar collector 6 enters the storage box 37, the solar collector 6 contacts the lever 38, causing the lever 38 to transmit power. Then, through the connecting rod 39, the power is transmitted to make the cover 40 rotate, and the second torsion spring 41 stores energy. The cover 40 covers the upper opening of the storage box 37. Therefore, the storage box 37 and the cover 40 protect the solar collector 6.

[0043] The above has described a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the application of the present invention.
