In addition, the heat collecting plate in a horizontal state is not easily hit by flying sand and stones, which can prevent the surface glass of the heat collecting plate from being hit by sand for a long time, resulting in the glass being scratched by sand and stones, affecting the light transmittance of the glass, and affecting the power generation and heating efficiency of the heat collecting plate. Moreover, when the heat collecting plate is adjusted from a horizontal state to an inclined state, the bottom of the heat collecting plate is disengaged from the movable bar, and the sand and stones on the heat collecting plate can fall from the gap between the movable bar and the heat collecting plate, thereby preventing the sand and stones from accumulating on the surface of the heat collecting plate and affecting the power generation and heating efficiency of the heat collecting plate; the movable rack rotates around the fixed gear, which can move the heat collecting plate into the outer frame, which can further reduce the probability of the heat collecting plate being hit by sand and stones, thereby playing a role in protecting the heat collecting plate.

[0031] 2. In the present invention, when the guide rod contacts the baffle bar, the baffle bar drives the fork frame to move into the lifting ring through the linkage rod; when the inner frame is horizontal, the fork frame is inserted into the slot; when the movable frame descends, the lifting ring drives the linkage frame to drive the pin shaft to descend through the fork frame, and the pin shaft is inserted into the guide rod under the action of the guide rail groove, so that the guide rod can move with the linkage frame, thereby adjusting the height of the solar collector according to the wind speed and controlling the accumulation of sand and stone on the solar collector; in addition, before the inner frame is level, the lifting ring rises and falls separately with the movable frame, so that the height adjustment structure is independent and does not affect the working state of the solar collector.

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figure 1-Figure 10 , the present invention provides a technical solution: a solar thermal photovoltaic composite heat collection device, including a heat collecting plate and a base 1, and also including a clamping member for clamping the heat collecting plate;

[0047] The outer frame 11 is slidably arranged with the clamping member and has an opening at one end;

[0048] The rotating seat 12 is fixed to the bottom of the outer frame 11 and is rotatably arranged with the base 1 through a rotating shaft, so as to adjust the angle of the heat collecting plate;

[0049] The telescopic rod 13 is rotatably arranged with the base 1, and drives the rotating base 12 to rotate through the connecting piece 14;

[0050] The fixed gear 15 is coaxial with the rotating shaft and fixed to the base 1 through a bracket 16;

[0051] The movable rack 17 is fixed to the clamping member and meshes with the fixed gear 15;

[0052] The clamping member includes an inner frame 21, which is fixed to the movable rack 17 and slidably arranged with the outer frame 11;

[0053] The positioning bar 22 is detachable from the inner frame 21 and has a U-shaped structure;

[0054] The movable bar 23 is slidably arranged with the outer frame 11 and moves in opposite directions with the positioning bar 22 through the driving structure, so that sand and stones can flow out from between the movable bar 23 and the inner frame 21;

[0055] Specifically, the base 1 is fixed, the clamping member clamps the heat collecting plate, the heat collecting plate is placed in the inner frame 21, and the positioning strip 22 presses the surface of the heat collecting plate to fix the heat collecting plate in the inner frame 21;

[0056] The external wind force level measuring device, when the wind force reaches the set value, the movable end of the telescopic rod 13 extends out of the connecting piece 14 to drive the rotating seat 12 to rotate around the rotating shaft, and the rotating seat 12 drives the heat collecting plate to rotate through the outer frame 11 and the inner frame 21; the inner frame 21 drives the movable rack 17 fixedly connected to it to rotate around the fixed gear 15. Figure 5, the movable rack 17 rotates counterclockwise around the fixed gear 15, and the movable rack 17 drives the inner frame 21 to move into the outer frame 11 under the action of the fixed gear 15, thereby moving the inner frame 21 into the outer frame 11; at the same time, the driving structure drives the movable bar 23 to separate from the heat collecting plate, and there is a gap between the heat collecting plate and the movable bar 23; until the heat collecting plate is horizontal, the horizontal heat collecting plate can reduce wind resistance and avoid being hit by sand and stones;

[0057] When the wind force level drops below the set value, the telescopic end of the telescopic rod 13 contracts, and the swivel seat 12 rotates in the opposite direction, so that the outer frame 11 drives the inner frame 21 and the heat collecting plate to rotate until the heat collecting plate rotates to a suitable tilt angle; at the same time, the driving structure drives the movable bar 23 to move toward the heat collecting plate. During the tilting process of the heat collecting plate, the sand and gravel accumulated on the heat collecting plate move along the heat collecting plate under the action of gravity, and pass through the gap between the movable bar 23 and the heat collecting plate. Finally, the heat collecting plate contacts the movable bar 23, and the movable bar 23 re-clamps the heat collecting plate to strengthen the positioning and clamping of the heat collecting plate.

[0058] To sum up, when the wind is strong, the solar collector is adjusted from an inclined state to a horizontal state, thereby reducing wind resistance and the probability of damage to the solar collector. In addition, the solar collector is not easily hit by flying sand and stones in a horizontal state, avoiding the surface glass of the solar collector from being hit by sand for a long time, causing the glass to be scratched by sand and stones, affecting the light transmittance of the glass, and affecting the power generation and heating efficiency of the solar collector. Moreover, when the solar collector is adjusted from a horizontal state to an inclined state, the bottom of the solar collector is disengaged from the movable bar 23, and the sand and stones on the solar collector can fall from the gap between the movable bar 23 and the solar collector, avoiding the accumulation of sand and stones on the surface of the solar collector and affecting the power generation and heating efficiency of the solar collector. The movable rack 17 rotates around the fixed gear 15, which can move the solar collector into the outer frame 11, and can further reduce the probability of the solar collector being hit by sand and stones, thereby playing a role in protecting the solar collector.

[0059] As a further solution of the present invention, the driving structure includes a spring plate 32, which is fixed to the movable bar 23 and intermittently engages with the inner frame 21 and descends synchronously;

[0060] The racks 31 facing away from each other intermittently rise synchronously with the inner frame 21, so that the spring plate 32 is engaged with the inner frame 21;

[0061] The opposite gear 33 is located between the opposite rack 31 and the spring plate 32;

[0062] The opposing spring 34 is disposed between the movable bar 23 and the outer frame 11 .

[0063] For details, see Figure 3When the inner frame 21 and the heat collecting plate move into the outer frame 11, the spring plate 32 engages with the inner frame 21 and descends synchronously, so that the heat collecting plate remains clamped; when the inner frame 21 rises, the spring plate 32 is separated from the inner frame 21, and the back-to-back springs 34 lift the movable bar 23, so that a gap is created between the movable bar 23 and the heat collecting plate, which facilitates the falling of sand and stones;

[0064] At the same time, the spring plate 32 drives the opposite rack 31 downward through the opposite gear 33, and the inner frame 21 contacts the opposite rack 31 first. The opposite rack 31 drives the spring plate 32 downward through the opposite gear 33, so that the spring plate 32 re-engages with the inner frame 21; thereby extending the contact time between the movable bar 23 and the heat collecting plate, avoiding sand and stones from being clamped between the movable bar 23 and the heat collecting plate.

[0065] As a further solution of the present invention, a guide rod 41 is fixedly provided at the bottom of the inner frame 21 and is slidably arranged with the rotating seat 12. A vertical rod 42 is rotatably provided at the end of the base 1. Wind cups 43 arranged in a circular array are fixedly provided at the top of the vertical rod 42. A height adjustment structure that adjusts the height according to the rotation speed of the wind cups 43 is installed on the vertical rod 42. A linkage structure is provided between the guide rod 41 and the height adjustment structure. The wind cups 43 measure the wind level.

[0066] For details, see 1. Figure 6 When the heat collecting plate is horizontal, the height adjustment structure adjusts the height of the guide rod 41 through the linkage structure to reduce the height of the heat collecting plate, so that the heat collecting plate goes deep into the outer frame 11, reducing the probability of the heat collecting plate being hit by sand and stones, thereby protecting the heat collecting plate;

[0067] As a further solution of the present invention, the height adjustment structure includes a movable frame 44 and a guide frame 45 fixed to the vertical rod 42, the movable frame 44 and the guide frame 45 are both arranged to rotate synchronously with the vertical rod 42, and a lifting spring 46 is fixed between the movable frame 44 and the guide frame 45;

[0068] The connecting rod 47 is rotatably arranged with the movable frame 44 and arranged in a circular array. The bottom of the connecting rod 47 passes through the guide rail frame 45 and is fixed with a counterweight ball 48;

[0069] For details, see Figure 6 , the vertical rod 42 rotates with the wind cup 43, and drives the movable frame 44 and the guide rail frame 45 to rotate synchronously with the vertical rod 42;

[0070] The movable frame 44 drives the counterweight ball 48 to rotate around the axis of the vertical pole 42 through the connecting rod 47. The counterweight ball 48 moves from the inside to the outside along the guide frame 45 under the action of centrifugal force. The counterweight ball 48 drives the movable frame 44 to descend through the connecting rod 47. The movable frame 44 drives the heat collecting plate to descend through the linkage structure, so that the height of the heat collecting plate can be adjusted according to the wind speed. It can avoid excessive sand and stones from accumulating on the heat collecting plate, and can also avoid the heat collecting plate from being hit by sand and stones.

[0071] As a further solution of the present invention, the linkage structure includes a lifting ring 51, which is rotatably arranged with the movable frame 44, and a slot 52 is opened on the side wall;

[0072] The linkage frame 53 has one end slidably connected to the lifting ring 51 and the other end slidably provided with a pin 54, and a locking spring 55 is provided between the pin 54 and the linkage frame 53;

[0073] The guide groove 56 is used to drive the pin 54 to move axially;

[0074] A linkage rod 57 is provided with a linkage spring 58 between the linkage frame 53, and a fork frame 59 matching the slot 52 and a stop bar 50 for intermittent contact with the guide rod 41 are provided at the end of the linkage rod 57;

[0075] For details, see Figure 1 , Figure 6-9 When the inner frame 21 rotates from tilted to horizontal, the guide rod 41 rotates accordingly. When the guide rod 41 contacts the baffle 50, the baffle 50 drives the fork frame 59 to move into the lifting ring 51 through the linkage rod 57; when the inner frame 21 is horizontal, the fork frame 59 is inserted into the slot 52; when the movable frame 44 descends, the lifting ring 51 drives the linkage frame 53 to drive the pin 54 to descend through the fork frame 59, and the pin 54 is inserted into the guide rod 41 under the action of the guide rail groove 56, so that the guide rod 41 can move with the linkage frame 53, thereby adjusting the height of the heat collecting plate according to the wind speed and controlling the accumulation of sand and stones on the heat collecting plate; in addition, before the inner frame 21 is not horizontal, the lifting ring 51 rises and falls alone with the movable frame 44, so that the height adjustment structure is independent and does not affect the working state of the heat collecting plate.

[0076] As a further solution of the present invention, the outer frame 11 is provided with a wedge block 62 for making way through a spring 61 for making way, the side wall of the inner frame 21 is provided with a positioning groove 63, and the bottom of the spring plate 32 is provided with a positioning block 64 intermittently matched with the positioning groove 63 and a bevel groove 65 for making way intermittently matched with the wedge block 62;

[0077] For details, see Figure 3 When the inner frame 21 rises, the inner frame 21 first rises a certain distance. During this process, the inner frame 21 drives the heat collecting plate to rotate from a horizontal state to an inclined state, and the sand and stones on the heat collecting plate roll down from the bottom of the movable bar 23 along the heat collecting plate;

[0078] The inner frame 21 contacts and pushes the opposite rack 31 to rise, and the opposite rack 31 drives the spring plate 32 and the movable bar 23 to descend through the opposite gear 33, and the positioning block 64 descends accordingly. When the positioning block 64 contacts the positioning groove 63, the spring plate 32 is engaged with the inner frame 21;

[0079] When the inner frame 21 descends, the inner frame 21 drives the movable bar 23 to descend through the spring plate 32. After the spring plate 32 passes over the wedge-shaped block 62, the inner frame 21 rotates from tilted to horizontal. The inner frame 21 can adjust the height of the heat collecting plate according to the wind force.

[0080] When the inner frame 21 rises again, the inner frame 21 drives the heat collecting plate to rotate from the horizontal state to the inclined state, and the spring plate 32 rises accordingly. When the oblique groove 65 contacts the wedge block 62, the spring plate 32 is completely deformed, so that the positioning block 64 is separated from the positioning groove 63. The opposite spring 34 instantly lifts the movable bar 23, and a gap is generated between the movable bar 23 and the heat collecting plate, which facilitates the sand and stones to roll down along the heat collecting plate.

[0081] As a further solution of the present invention, a return spring 71 is fixed between the opposite rack 31 and the outer frame 11, a trigger plate 72 is fixed on the side wall of the inner frame 21 and is located directly below the opposite rack 31, and a clearance groove 73 is opened on the movable bar 23;

[0082] For details, see Figure 3 , when the trigger plate 72 rises with the inner frame 21, the opposite rack 31 contacts it and rises and stretches the reset spring 71, the movable bar 23 descends, and after the spring plate 32 is engaged with the inner frame 21, the spring plate 32 descends, the opposite rack 31 continues to rise and stretches the reset spring 71, and after the spring plate 32 is disengaged from the opposite gear 33, the reset spring 71 drives the opposite rack 31 to descend; after the spring plate 32 is separated from the inner frame 21, the movable bar 23 drives the spring plate 32 to rise to the top, and resets the opposite rack 31 through the opposite gear 33;

[0083] During this process, when the inner frame 21 moves to the bottom, the height of the heat collecting plate can be freely adjusted up and down to protect the heat collecting plate. The movable bar 23 contacts with it to increase the clamping force of the heat collecting plate; when the heat collecting plate rotates, the wedge block 62 separates the spring plate 32 from the inner frame 21, and the movable bar 23 separates from the heat collecting plate, so that the accumulated sand can fall from the bottom of the movable bar 23 to avoid sand and stone accumulation, which affects the power generation and heat generation of the heat collecting plate; finally, the movable bar 23 contacts with the heat collecting plate again to restore the clamping of the heat collecting plate.

[0084] As a further solution of the present invention, the pin shaft 54 ​​includes a front pin 81 and a rear pin 82, and a buffer spring 83 is provided between the front pin 81 and the rear pin 82, the linkage rod 57 and the fork frame 59;

[0085] For details, see Fig.10 The front pin 81 can move into the rear pin 82 to play a delaying role, thereby preventing the pin shaft 54 ​​from squeezing the guide rod 41 and affecting the synchronous movement of the guide rod 41 and the linkage frame 53.
