Description

Technical Field

[0001] The present invention belongs to the technical field related to photovoltaic concentrating solar thermal power generation, and particularly relates to a support structure for a concentrating device of a photovoltaic power station with adjustable spacing. Background Technique

[0002] A concentrator is a device that focuses scattered light onto a specific area or focus through optical principles, aiming to increase the light energy density or optimize the transmission efficiency of optical signals. Its core function is to change the propagation path of light through reflection, refraction, or diffraction, etc., so as to form a high-intensity light spot in the target area, meeting the requirements for high energy density or high-precision light control in fields such as energy, communication, scientific research, or medical treatment. The solar concentrator is the main component of the concentrating system and is also one of the key technologies in the research of concentrating solar cells. The multiple of the light energy density increased by the concentrator is called the concentration ratio, which is an important parameter indicating the performance of the concentrator. The energy density concentration ratio is expressed as the ratio of the average energy density absorbed by the absorber to the incident energy density. When the optical system is ideal and there is no energy loss in the middle, the degree of concentration can also be expressed by the geometric concentration ratio, that is, the ratio of the opening area of the concentrator receiving solar radiation to the surface area of the absorber absorbing light energy. With the global energy structure transforming towards cleaner energy, photovoltaic power generation has become one of the mainstream technologies due to its rich resources, low carbon, and environmental protection. The concentrating photovoltaic technology focuses sunlight onto the receiver through optical elements, which can increase the light intensity by hundreds of times and significantly improve the power generation efficiency per unit area. However, it also poses higher requirements for the support structure: it is necessary to accurately track the sun's trajectory and maintain the stability of the concentrating components. According to the existing published document CN107147353B, in order to improve the stability of the concentrating device during operation, a corresponding support structure is generally used to stabilize the position of the concentrating device.

[0003] However, when the existing concentrators are in use, in order to improve the efficiency of light concentration, multiple groups of reflecting lenses are used to uniformly reflect light onto a single receiver. Over a long period of time, it is necessary to ensure that the air between multiple groups of reflecting lenses can circulate quickly to ensure the rapid dissipation of heat. However, in the existing concentrating device, the support structure and the reflecting lenses are mostly connected by bolts. However, this connection method is not convenient for controlling the distance between multiple reflecting lenses, so it will affect the heat dissipation efficiency between multiple reflecting lenses. At the same time, when the existing support structure is connected to the reflecting lenses, the adjusting plate is mostly used to connect the two ends of the reflecting lenses. When controlling the angle adjustment of the reflecting lenses, the angle adjustment is achieved by controlling the rotation path of the reflecting lenses along the adjusting plate. When using this angle adjustment method, multiple people need to cooperate. Moreover, when a single person operates the rotation of a single reflecting lens, since the length of the reflecting lenses used in the photovoltaic power station is too long, it is difficult to achieve the angle adjustment of the reflecting lenses due to excessive torque. For this reason, we provide a support structure for a concentrating device of a photovoltaic power station with adjustable spacing to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a support structure for a concentrating device of a photovoltaic power station with adjustable spacing. By controlling the tooth pitch bar to move out of the lower end of the support bar, the positioning component and the adjustment component are disconnected, and the reflected light component can be moved to adjust the distance between two adjacent reflected light components, facilitating the adjustment of the air flow distance between two adjustment components according to actual needs. At the same time, control the forward and backward movement of the progressive screw. As a result, the progressive screw will drive the locking plate to rotate in both forward and reverse directions, thereby achieving the adjustment of the angle of the reflected light component according to the position of the receiver, and enabling a single person to perform the adjustment work and improving the adjustment efficiency.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention provides a support structure for a light - concentrating device of a photovoltaic power station with adjustable spacing, which includes two sets of support components symmetrically arranged front and back. Each support component includes a support bar. Positioning ports are opened on the lower end surfaces of the support bars. A positioning component is arranged directly below each set of support components. The positioning component includes a positioning strip plate connected to the lower end surface of the support bar and a pitch bar fixed on the upper end surface of the positioning strip plate. The pitch bar is arranged in the adjacent positioning ports. There are multiple sets of adjustment components evenly distributed left and right at the position between the two sets of support components. The adjustment component includes an assembly plate located between the two support bars and a locking plate located directly above the assembly plate. Progressive screws are arranged at the position between the assembly plate and the locking plate. A reflected - light component for reflecting sunlight, which includes a reflecting lens connected to the locking plate by bolts. A strip - shaped cylinder is fixed on the upper end surface of each assembly plate. The progressive screw passes through the corresponding strip - shaped cylinder. Threaded sleeves are fixed at the front and rear parts of the lower end surface of the locking plate, and the threaded sleeves are helically connected to the adjacent progressive screws. Two grooves are evenly arranged along the circumferential wall on the outer side wall of the progressive screw. Two convex strips sliding in the grooves are fixed on the inner wall of each strip - shaped cylinder. Arc - shaped holes are opened on the upper end surfaces of the assembly plates on the left and right sides of the strip - shaped cylinder. Arc - shaped rods are fixed at the left and right parts of the lower end of the locking plate on the left and right sides of the strip - shaped cylinder, and each arc - shaped rod respectively slides through the corresponding arc - shaped hole.

[0006] The present invention is further configured such that mounting plates are fixed on the side walls of the two support bars opposite to the reflecting lens, and bottom brackets are fixed on the two end surfaces of the lower surface of the mounting plates.

[0007] The present invention is further configured such that connecting rods are fixed on the upper end surfaces of the positioning strip plates on the left and right sides of the pitch bar. Telescopic grooves are opened at the corresponding positions on the upper end surfaces of the support bars. A blocking hole communicating with the inside of the telescopic groove is opened on the lower end surface of the support bar.

[0008] The present invention is further configured such that a circular plate connected to the inner wall of the telescopic groove is arranged at the end surface of the connecting rod passing through the blocking hole. An assembly screw helically connected to the connecting rod is fixed on the lower end surface of the circular plate. A positioning spring is sleeved on the outer side part of the connecting rod inside the telescopic groove, and the two ends of the positioning spring respectively abut against the inner bottom surface of the telescopic groove and the lower end surface of the circular plate.

[0009] The present invention is further configured such that moving ports communicating with the inside of the positioning ports are opened on the opposite end surfaces of the two support bars. A loop - shaped frame bar is fixed on the lower end surface of each assembly plate. Abutting blocks connected to the side surfaces of the adjacent support bars are fixed at the front and rear parts of the lower end surface of the loop - shaped frame bar. Tooth blocks arranged inside the moving ports are bolt - connected to the end surfaces of the abutting blocks close to the support bars, and the tooth blocks are meshed with the corresponding pitch bars.

[0010] The present invention is further configured such that an active strip board is disposed inside each set of U-shaped frame bars, a connecting strip board bolted to the lower side wall of the U-shaped frame bars is disposed directly below each active strip board, friction blocks are fixed on the upper surfaces of both ends of each active strip board passing through the U-shaped frame bars, and grip bars abutting against the upper surfaces of the friction blocks are fixed at the front and rear ends of the progressive screw.

[0011] The present invention is further configured such that a plurality of position-limiting holes arranged in a front-back uniform manner are formed in the upper end surfaces of each set of active strip boards, a plurality of position-limiting rods respectively passing through the interiors of the position-limiting holes are fixed on the upper end surfaces of the connecting strip boards, a plurality of pushing springs respectively sleeved on the position-limiting rods are fixed on the upper end surfaces of the connecting strip boards, and each pushing spring abuts against the lower end surface of the active strip board.

[0012] The present invention has the following beneficial effects: When controlling the movement of the pitch bar, the pitch bar is moved out of the positioning opening. At this time, the pitch bar is disengaged from the meshing connection with the tooth block, so that the pitch bar can be disengaged from the connection relationship with the adjustment assembly, and the position of the locking plate and the assembly plate can be controlled to slide between the two sets of support bars. When the distance between two adjacent adjustment assemblies is adjusted, the positioning strip board is loosened. Thus, the positioning spring drives the positioning strip board and the pitch bar to reset, and the pitch bar is re-engaged with the tooth block to position the position of the adjustment assembly, realizing the adjustment of the distance between two adjacent reflection light assemblies, facilitating the adjustment of the air flow distance between the two adjustment assemblies according to actual needs, and facilitating the heat dissipation between the two reflection light assemblies.

[0013] When controlling the forward and backward movement of the progressive screw, the progressive screw will drive the threaded sleeve to have a tendency to rotate and move forward and backward. Through the arc-shaped rod in the arc-shaped hole, the threaded sleeve is limited so that the threaded sleeve does not move forward and backward. When the progressive screw moves forward and backward, it will directly drive the rotational movement of the threaded sleeve. The threaded sleeve will drive the locking plate to rotate in the left-right direction, thereby realizing the rotational movement of the locking plate driving the reflecting lens, realizing the adjustment of the angle of the reflection light assembly according to the position of the receiver, and realizing that the adjustment work can be carried out by a single person and improving the adjustment efficiency.

Detailed implementation manners

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Embodiment 1 Please refer to Figure 1 、 Figure 2 、 Figure 7 、 Figure 11 and Figure 12 This is the first embodiment of the present invention, which provides a support structure for a light - collecting device of a photovoltaic power station with adjustable spacing. By controlling the tooth - pitch bar 201a to move out of the lower end position of the support bar 101, the positioning component 200 is disconnected from the adjustment component 300, and the reflecting light component 400 can be moved, so as to adjust the spacing between two adjacent reflecting light components 400. This is convenient for adjusting the air - flow distance between two adjustment components 300 according to actual needs. At the same time, by controlling the forward - and - backward movement of the progressive screw 304, the progressive screw 304 will drive the locking plate 302 to rotate in both forward and reverse directions, so as to adjust the angle of the reflecting light component 400 according to the position of the receiver, and realize that the adjustment work can be carried out by a single person, and improve the adjustment efficiency.

[0030] Specifically, there are two sets of support components 100 arranged symmetrically in the front - and - back direction. The support component 100 includes a support bar 101. A positioning component 200 is arranged directly below each set of support components 100. The positioning component 200 includes a positioning strip plate 201 connected to the lower end surface of the support bar 101 and a tooth - pitch bar 201a fixed to the upper end surface of the positioning strip plate 201. There are multiple sets of adjustment components 300 arranged evenly in the left - and - right direction at the position between the two sets of support components 100, and a reflecting light component 400 for reflecting sunlight. Through the setting and use of the above - mentioned structure, when it is necessary to adaptively adjust the spacing between two adjacent reflecting light components 400, the positioning strip plate 201 can be controlled to move downward, so that the positioning strip plate 201 is disengaged from the lower end surface of the support bar 101. Then the positioning strip plate 201 will drive the tooth - pitch bar 201a to move downward accordingly. At this time, the adjustment component 300 is disengaged from the positioning component 200. At this time, the adjustment component 300 can be directly controlled to move along the support bar 101. Further, the movement of the adjustment component 300 will directly drive the position adjustment of the reflecting light component 400. At the same time, when controlling the adjustment component 300 to work, the adjustment component 300 will drive the rotation of the reflecting light component 400, which can improve the adjustment efficiency.

[0031] According to Figure 2 、 Figure 3 and Figure 7, positioning openings 101c are provided on the lower end surfaces of the support bars 101, and the pitch bar 201a is disposed in the positioning openings 101c adjacent thereto. The adjustment assembly 300 includes an assembly plate 301 located between the two groups of support bars 101 and a locking plate 302 positioned directly above the assembly plate 301. Progressive screws 304 are provided at positions between the assembly plate 301 and the locking plate 302. The reflected light assembly 400 includes a reflecting lens 401 connected to the locking plate 302 by bolts; When using the structure arranged as above, when controlling the movement of the pitch bar 201a, the pitch bar 201a is moved out of the inside of the positioning opening 101c, whereby the connection relationship between the pitch bar 201a and the adjustment assembly 300 can be disengaged. The positions of the locking plate 302 and the assembly plate 301 between the two groups of support bars 101 can be controlled to slide, so as to adjust the distance between the two reflecting lenses 401. At the same time, the progressive screw 304 is controlled to move in the front-back direction. And since the progressive screw 304 is limited and cannot rotate, the progressive screw 304 will control the locking plate 302 to rotate about the axis of the progressive screw 304, and the locking plate 302 will drive the reflecting lens 401 to adjust the angle, improving the adjustment efficiency.

[0032] Further, according to Figure 3 and Figure 4 it can be known that mounting plates 103 are fixed to the side walls of the two groups of support bars 101 opposite to the reflecting lenses 401. Footrests 102 are fixed to both end faces of the lower surface of the mounting plate 103. At the same time, through the rivet connection between the footrests 102 and the ground, the footrests 102 support the support bars 101.

[0033] It should be noted that when installing the receiver, the receiver is installed at the directly upper position of the entire device. Both ends of the receiver are bolted to the mounting plate 103 through rods, and then the mounting plate 103 supports and stabilizes the position of the receiver.

[0034] Embodiment 2 Please refer to Figure 3 , Figure 4 and Figure 5 , on the basis of Embodiment 1, in this embodiment, by using the positioning spring 201c, the rapid reset of the positioning strip 201 can be facilitated. At the same time, through the combined use of the connecting rod 201b and the circular plate 202, the positioning strip 201 can be disassembled to achieve the disassembly and assembly work.

[0035] Specifically, connecting rods 201b are fixed to the upper end faces of the positioning strip plates 201 on the left and right sides of the pitch bar 201a. Telescopic grooves 101b are provided at the positions corresponding to the connecting rods 201b on the upper end faces of the support bars 101. Stopping holes 101d communicating with the interiors of the telescopic grooves 101b are provided on the lower end faces of the support bars 101. Circular plates 202 in contact with the inner walls of the telescopic grooves 101b are arranged on the end faces of the connecting rods 201b passing through the stopping holes 101d. Assembly screws 202a screwed to the connecting rods 201b are fixed to the lower end faces of the circular plates 202. A positioning spring 201c is sleeved on the outer side of the connecting rod 201b inside the telescopic groove 101b, and the two ends of the positioning spring 201c are respectively abutted against the inner bottom surface of the telescopic groove 101b and the lower end face of the circular plate 202.

[0036] Through the above structural arrangement and use, in order to facilitate the control of the movement of the pitch bar 201a out of the positioning opening 101c, the staff can directly control the downward movement of the positioning strip plate 201. The positioning strip plate 201 will drive the pitch bar 201a to move out of the positioning opening 101c. At the same time, when the positioning strip plate 201 moves, it will drive the connecting rod 201b to slide along the stopping hole 101d, and the connecting rod 201b drives the circular plate 202 to move downward in the telescopic groove 101b. When the circular plate 202 moves downward, it will compress the positioning spring 201c. Therefore, when the positioning strip plate 201 is released, the positioning spring 201c pushes the circular plate 202 to move upward, thereby driving the connecting rod 201b to reset upward, and then driving the positioning strip plate 201 to reset upward to control the pitch bar 201a to move back into the positioning opening 101c. At the same time, when the entire positioning strip plate 201 needs to be disassembled, by rotating the circular plate 202, the circular plate 202 drives the assembly screw 202a to disengage from the upper end face position of the connecting rod 201b. Then, the connecting rod 201b can directly move out from the lower port position of the stopping hole 101d, and the positioning strip plate 201 can be removed from the lower end portion position of the support bar 101 to disassemble and replace the positioning assembly 200. When installing the positioning strip plate 201, the connecting rod 201b is inserted through the lower port position of the stopping hole 101d and passes through the inside of the positioning spring 201c. Then, the assembly screw 202a is threadedly connected to the connecting rod 201b, and the positioning strip plate 201 can be installed at the lower end face position of the support bar 101.

[0037] Embodiment 3 Please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 6 On the basis of Embodiment 1, through the meshing operation between the tooth block 303 and the pitch bar 201a in this embodiment, the positioning or sliding of the adjustment assembly 300 can be facilitated.

[0038] Specifically, moving ports 101a communicating with the inside of the positioning ports 101c are formed on the opposite end faces of the two groups of support bars 101. A return-shaped frame bar 305 is fixed to the lower end face of each group of assembly plates 301. Contact blocks 305a contacting the side faces of the adjacent support bars 101 are fixed to the front and rear parts of the lower end face of the return-shaped frame bar 305. Tooth blocks 303 disposed inside the moving ports 101a are bolted to the end faces of the contact blocks 305a close to the support bars 101, and the tooth blocks 303 are engaged with the corresponding pitch bars 201a. With the above structure, since the tooth blocks 303 enter the positioning ports 101c from the positions of the moving ports 101a, the tooth blocks 303 can be engaged with the pitch bars 201a. When the positioning bar plate 201 controls the pitch bars 201a to move downward in the positioning ports 101c, the pitch bars 201a are disengaged from the meshing connection with the tooth blocks 303 at this time. Therefore, the return-shaped frame bars 305 can be controlled to slide along the side positions of the support bars 101. At the same time, the tooth blocks 303 and the contact blocks 305a are bolted together, so the two can be disassembled, thereby controlling the tooth blocks 303 to be disengaged from the contact blocks 305a. Therefore, when the positioning bar plate 201 is disengaged from the assembly relationship with the support bars 101, the tooth blocks 303 can also be taken out from the positioning ports 101c. Then, by controlling the two groups of support bars 101 to move in opposite and away directions, the contact blocks 305a can be controlled to move out of the moving ports 101a, and the return-shaped frame bars 305 can be taken out from the positions between the two groups of support bars 101.

[0039] Embodiment 4 Please refer to Figure 6 , Figure 7 , Figure 9 and Figure 10 On the basis of Embodiment 1, in this embodiment, through the spiral cooperation between the threaded sleeves 302a and the progressive screws 304, it is convenient to drive the angle adjustment of the locking plates 302.

[0040] Specifically, a strip-shaped cylinder 301a is fixed to the upper end face of each group of assembly plates 301. The progressive screws 304 pass through the corresponding strip-shaped cylinders 301a. Two grooves 304b evenly distributed along the circumferential wall are formed on the outer side wall of the progressive screws 304. Two convex strips 301c respectively sliding in the grooves 304b are fixed to the inner wall of each strip-shaped cylinder 301a. Threaded sleeves 302a are fixed to the front and rear parts of the lower end face of the locking plates 302, and the threaded sleeves 302a are in spiral connection with the adjacent progressive screws 304. Arc-shaped holes 301b are formed on the upper end faces of the assembly plates 301 on the left and right sides of the strip-shaped cylinders 301a. Arc-shaped rods 302b are fixed to the left and right parts of the lower end of the locking plates 302 on the left and right sides of the strip-shaped cylinders 301a, and each arc-shaped rod 302b respectively slides through the corresponding arc-shaped hole 301b. Through the setting and use of the above structure, since the convex strip 301c is located in the groove 304b, the convex strip 301c limits the progressive screw 304, so that the progressive screw 304 cannot rotate in the strip-shaped cylinder 301a. Therefore, when controlling the forward and backward movement of the progressive screw 304, the progressive screw 304 will drive the thread sleeve 302a to have a tendency to rotate and move forward and backward. At the same time, since the arc-shaped rod 302b slides through the arc-shaped hole 301b, the arc-shaped rod 302b limits the thread sleeve 302a, so that the thread sleeve 302a will not move forward and backward. When the progressive screw 304 moves forward and backward, it will directly drive the rotational movement of the thread sleeve 302a. The thread sleeve 302a will drive the locking plate 302 to rotate in the left and right directions, so as to realize the angular rotation of the locking plate 302 driving the reflecting lens 401. At the same time, when the locking plate 302 rotates, it will drive the arc-shaped rod 302b to slide in the arc-shaped hole 301b.

[0041] Embodiment 5 Please refer to Figure 7 and Figure 8 , on the basis of Embodiment 1, this embodiment pushes the movable strip 306 through the pushing spring 306e, so that the movable strip 306 stably pushes the friction block 306a to closely fit with the grip rod 304a, so as to ensure the stable position of the forward and backward adjustment of the grip rod 304a.

[0042] Specifically, a movable strip 306 is arranged inside each set of loop-shaped frame strips 305. A connecting strip 306c bolted to the inner bottom of the loop-shaped frame strip 305 is arranged directly below each movable strip 306. Friction blocks 306a are fixed on the upper surfaces of the two ends of each movable strip 306 passing through the loop-shaped frame strip 305. Grip rods 304a abutted against the upper surfaces of the friction blocks 306a are fixed at the front and rear ends of the progressive screw 304. A plurality of limiting holes 306b arranged in a front and rear uniform distribution are formed in the upper end surfaces of each set of movable strips 306. A plurality of limiting rods 306d respectively passing through the inside of the limiting holes 306b are fixed on the upper end surface of the connecting strip 306c. A plurality of pushing springs 306e respectively sleeved on the limiting rods 306d are fixed on the upper end surface of the connecting strip 306c, and each pushing spring 306e abuts against the lower end surface of the movable strip 306 respectively; When the staff needs to drive the progressive screw 304 to move by controlling the grip rod 304a through the above - mentioned structure, the movable strip 306 is controlled to move downward in the loop - shaped frame strip 305. At the same time, when the movable strip 306 moves downward, the pushing spring 306e will be compressed. The movable strip 306 will drive the friction block 306a to move downward and disengage from the grip rod 304a. At this time, the movement of the grip rod 304a in the front - rear direction can be controlled, thereby driving the progressive screw 304 to move in the front - rear direction. After the position of the progressive screw 304 has been adjusted, the movable strip 306 is released. Then, the pushing spring 306e will push the movable strip 306 to reset upward. The movable strip 306 controls the friction block 306a to come into contact with the surface of the grip rod 304a again. Thus, the friction block 306a closely fits with the grip rod 304a, increasing the friction between the two, and preventing the spontaneous movement of the grip rod 304a. When the movable strip 306 moves downward, the movable strip 306 will slide along the limit rod 306d through the limit hole 306b. The position of the limit hole 306b is limited by the limit rod 306d to ensure that the movable strip 306 moves stably in the loop - shaped frame strip 305. At the same time, the bolt between the connecting strip 306c and the loop - shaped frame strip 305 is unscrewed, and the distance between the movable strip 306 and the connecting strip 306c is shortened, so that the friction block 306a moves to the port position of the loop - shaped frame strip 305. Thus, the movable strip 306 can be pulled out from the inside of the loop - shaped frame strip 305 to disassemble the two.
