DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0029] Example one: please refer to Figures 1-3 The present application provides the following technical solutions:

[0030] A solar heat storage device for a greenhouse, comprising a greenhouse 1, the greenhouse 1 is provided with two groups of photovoltaic components, the photovoltaic components comprise guide grooves 2 laid along the cross-sectional edges of the greenhouse 1, two round rods 3 on the side surfaces of the guide grooves 2, a sliding plate 4 commonly arranged to slide in the middle of the round rods 3, a sliding column 5 arranged at one end of the round rods 3, the sliding column 5 being in sliding cooperation with the guide grooves 2, a solar heat collector 6 commonly connected to the other end of the round rods 3, a spring one 7 arranged outside the round rods 3, and the two ends of the spring one 7 being connected with the sliding plate 4 and the solar heat collector 6 respectively; a motor 8 arranged on the sliding plate 4, a friction roller 9 arranged on the rotating shaft of the motor 8, and the friction roller 9 being in friction cooperation with the outer side surfaces of the guide grooves 2.

[0031] The working principle of the embodiment is as follows: the spring 7 provides elastic force, so that the sliding plate 4 is always pressed against the guide groove 2, and 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, and the friction roller 9 rolls on the side surface of the guide groove 2, so that the two sliding columns 5 simultaneously slide on the guide groove 2, thereby driving the round rod 3 and the solar collector 6 to move along the guide groove 2. The solar collector 6 can move on the roof and side wall 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, thereby improving the efficiency of the solar collector 6 in absorbing sunlight.

[0032] In the specific embodiment one, the difference of the embodiment two is that:

[0033] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , the photovoltaic module comprises two guide rods 10 fixed on the side surface of the greenhouse 1, a vertical plate 11 is slidably arranged on the two guide rods 10, a spring 12 is arranged outside the guide rod 10, the two ends of the spring 12 are connected with the greenhouse 1 and the vertical plate 11 respectively, a wiping strip 13 is arranged on one side of the vertical plate 11 close to the solar collector 6, and a spray head seat 14 for cleaning the solar collector 6 is arranged below the vertical plate 11.

[0034] Specifically, the spray head seat 14 is connected with a water source, when the solar collector 6 moves from bottom to top, the spray head seat 14 sprays clean water to clean the surface of the solar collector 6, and the wiping strip 13 contacts with 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 with the solar collector 6.

[0035] The lower ends of the two ends of the vertical plate 11 are respectively provided with a side plate 15, the opposite surfaces of the two side plates 15 are respectively provided with a groove plate 16, the middle part of the groove plate 16 is provided with a groove, the groove of the groove plate 16 is sequentially composed of an upper inclined groove 1601, a vertical groove 1602 and a lower inclined groove 1603 from top to bottom, and the upper surface of the groove plate 16 is provided with an inclined surface 1604.

[0036] The inner side of the solar collector 6 is fixedly provided with a rotating seat 17, a connecting plate 18 is rotatably arranged on the rotating seat 17, the end of the connecting plate 18 is provided with a sliding shaft 19 for clamping into the groove of the groove plate 16, the other side of the connecting plate 18 is provided with a baffle 22, the rotating seat 17 is provided with a fixed roof plate 23 for blocking the baffle 22, a spring shaft 20 is arranged between the connecting plate 18 and the solar collector 6, and the two ends of the spring shaft 20 are respectively hinged with the connecting plate 18 and the solar collector 6.

[0037] The working principle of the embodiment is as follows: in the original state, there is a gap between the solar collector 6 and the wiping strip 13, the spring shaft 20 is in the elongated state, the baffle 22 is in contact with the baffle rod 21, and the rotation of the connecting plate 18 is prevented. The motor 8 provides driving force, and the working principle is the same as that of the above embodiment, so that the solar collector 6 moves up and down on the side of the greenhouse 1. During the downward movement of the solar collector 6, the sliding shaft 19 is in contact with the inclined surface 1604, which drives the connecting plate 18 to rotate clockwise around the rotating seat 17, the spring shaft 20 is retracted, and the sliding shaft 19 moves along the outer side of the groove plate 16. Because the spring force of the spring shaft 20 is small, the force of the sliding shaft 19 on the groove plate 16 is small, so the vertical plate 11 above the side plate 15 does not slide on the guide rod 10, and the gap between the wiping strip 13 and the solar collector 6 is always maintained, so that the solar collector 6 is not scratched by the wiping strip 13 due to the presence of dirt on the surface of the solar collector 6. During the upward movement of the solar collector 6, the nozzle seat 14 sprays clean water on the surface of the solar collector 6 to clean the dirt on the surface of the solar collector 6; at the same time, the sliding shaft 19 is aligned 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. Because the connecting plate 18 cannot rotate counterclockwise, the sliding shaft 19 drives the groove plate 16 to move towards the greenhouse 1, so that the wiping strip 13 is in contact with the solar collector 6. When the sliding shaft 19 slides in the vertical groove 1602, the wiping strip 13 is always in contact with the solar collector 6 to wipe the surface of the solar collector 6. After the wiping strip 13 is separated from the solar collector 6, the sliding shaft 19 also separates from the groove of the groove plate 16 from the upper opening of the upper inclined groove 1601.

[0038] Embodiment three: the difference between this embodiment and embodiment two is that:

[0039] Please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 , on the basis of embodiment two, the top of the greenhouse 1 is triangular, and the top of the greenhouse 1 is provided with a fixed roof plate 23 on both sides of the bottom, and two movable roof plates 24 are slidably arranged on the fixed roof plate 23. One of the two movable roof plates 24 is connected with the upper surface of the other movable roof plate 24 by a cross plate 25, a rotating column 27 is vertically arranged on the upper surface of the cross plate 25, a rotating plate 26 is rotatably arranged on the top of the rotating column 27, and a torsional spring 28 is arranged outside the rotating column 27, and the two ends of the torsional spring 28 are connected with the cross plate 25 and the rotating plate 26 respectively.

[0040] Specifically, when one end of the rotating plate 26 is subjected to force, the rotating plate 26 rotates on the rotating column 27, and the torsional spring 28 stores energy, and the two movable roof plates 24 below do not move. When a pushing force is 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 make the two movable roof plates 24 move downwards along the fixed roof plate 23, so that the roof of the greenhouse 1 becomes open

[0041] The bottom of the solar collector 6 is provided with a push rod 29 for driving the rotating plate 26, and when the solar collector 6 of each photovoltaic assembly passes through the rotating plate 26, the two push rods 29 simultaneously apply a pushing force to both ends of the rotating plate 26. When the solar collector 6 of one photovoltaic assembly passes through the rotating plate 26, one push rod 29 applies a pushing force to one end of the rotating plate 26.

[0042] Each movable roof plate 24 is provided with a rack 30 which is slidingly arranged in a sliding groove 31, and the lower part of the sliding groove 31 is engaged with a gear one 32. The two gear ones 32 on each side are fixedly arranged on a rotating shaft one 33 which is rotatably arranged below the corresponding fixed roof plate 23. The lower part of the two gear ones 32 on one side is respectively engaged with a gear two 34, and the two gear twos 34 are fixedly arranged on a rotating shaft two 35 which is rotatably arranged below the corresponding fixed roof plate 23. The rotating shaft one 33 and the rotating shaft two 35 between the two gear ones 32 on the other side are connected by a transmission mechanism 36, and the two rotating wheels of the transmission mechanism 36 are respectively arranged on the rotating shaft one 33 and the rotating shaft two 35.

[0043] The transmission mechanism 36 is composed of two transmission wheels and a transmission belt. When one of the transmission wheels rotates, the power is transmitted through the transmission belt to make the other transmission wheel rotate synchronously.

[0044] Specifically, when the two movable roof plates 24 below the rotating plate 26 move downward along the fixed roof plate 23, the racks 30 synchronously slide in the sliding grooves 31, and the power is transmitted through the corresponding sliding grooves 31 to make the corresponding rotating shaft one 33 rotate synchronously, and then the power is transmitted through the transmission mechanism 36 to make the rotating shaft two 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 to change the roof of the greenhouse 1 into an open-air one.

[0045] The working principle of the embodiment is as follows: when it is not necessary to change the roof of the greenhouse 1, each photovoltaic assembly is operated separately each time to ensure that only the solar collector 6 of one photovoltaic assembly passes through the rotating plate 26, and the corresponding push rod 29 passes through the rotating plate 26 to make the rotating plate 26 rotate, and the torsional spring one 28 stores energy. After the push rod 29 leaves the rotating plate 26, the torsional spring one 28 drives the rotating plate 26 to return to the original rotation. When it is necessary to change the roof of the greenhouse 1 into an open-air one, the solar collector 6 of two photovoltaic assemblies passes through the rotating plate 26 at the same time, and the two push rods 29 simultaneously apply a pushing force to both ends of the rotating plate 26. The solar collector 6 will not rotate around the rotating column 27, but will make the two movable roof plates 24 on the side 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 to change the roof of the greenhouse 1 into an open-air one, and the sunlight directly irradiates into the interior of the greenhouse 1.

[0046] Embodiment four: based on the specific embodiment three, the different point of this embodiment is that:

[0047] Please refer to Figure 1 , Figure 2 and Figure 9 , the other side of the guide rod 10 is provided with a storage box 37, the bottom of the storage box 37 is hinged to the middle part of the lever 38, the upper edge of the storage box 37 is hinged to the cover 40, the pivot of the cover 40 is sleeved with the torsion spring 41, the two ends of the torsion spring 41 are connected with the storage box 37 and the cover 40 respectively, the upper and lower ends of the connecting rod 39 are hinged to the outer end of the lever 38 and the cover 40 respectively.

[0048] The working principle of this embodiment is: when the environment becomes bad, the solar collector 6 needs to be protected. When the solar collector 6 enters the storage box 37, the solar collector 6 contacts with the lever 38, the lever 38 is driven, and the power is transmitted through the connecting rod 39, the cover 40 is rotated, the torsion spring 41 is energized, and the upper opening of the storage box 37 is covered by the cover 40, so the storage box 37 and the cover 40 protect the solar collector 6.

[0049] The above describes one embodiment of the application in detail, but the content is only the preferred embodiment of the application, and cannot be considered as limiting the scope of the application. Any equivalent changes and improvements made according to the scope of the application should still belong to the scope of the application.
