Description

Technical Field

[0001] The present invention belongs to the technical field related to photovoltaic concentrating and heat-collecting power generation, and in particular relates to a support structure of a concentrating device of a photovoltaic power station with adjustable spacing. Background Art

[0002] A concentrator is a device that uses optical principles to focus scattered light to a specific area or focus, aiming to increase light energy density or optimize the transmission efficiency of light signals. Its core function is to change the propagation path of light by reflection, refraction or diffraction, so that it forms a high-intensity light spot in the target area, meeting the needs of energy, communications, scientific research or medical fields for high energy density or high-precision light control. The solar concentrator is the main component of the concentrating system and one of the key technologies in the research of concentrating solar cells. The multiple by which the concentrator increases the light energy density is called the concentration ratio, which is an important parameter to mark 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 relatively ideal, the concentration ratio is 1 / 2 of the total energy density. There is no energy loss along the way, and the degree of concentration can also be expressed by the geometric concentration ratio, which is the ratio of the opening area of ​​the concentrator to receive solar radiation to the surface area of ​​the absorber to absorb light energy. As the global energy structure transforms to clean energy, photovoltaic power generation has become one of the mainstream technologies due to its abundant resources, low carbon and environmental protection. Concentrated 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 puts forward higher requirements on the supporting structure: it is necessary to accurately track the trajectory of the sun and maintain the stability of the concentrating component. According to the existing public document CN107147353B, in order to improve the stability of the concentrating device, a corresponding supporting structure is generally used to stabilize the position of the concentrating device.

[0003] However, in order to improve the efficiency of focusing, existing concentrators use multiple sets of reflective lenses to uniformly reflect light onto a single receiver. Over a long period of time, it is necessary to ensure that air can circulate quickly between the multiple reflective lenses to ensure rapid heat dissipation. However, the support structure and reflective lenses in existing concentrators are mostly connected by bolts. However, this connection method cannot easily control the spacing between the multiple reflective lenses, thus affecting the heat dissipation efficiency between the multiple reflective lenses. At the same time, the support structure and reflective lenses are mostly connected by adjusting plates connected to the ends of the reflective lenses. When controlling the angle of the reflective lenses, the angle is adjusted by controlling the reflective lenses along the rotation path of the adjusting plates. When using this angle adjustment method, multiple people are required to work together. Moreover, when a single person rotates a single reflective lens, the reflective lens used in photovoltaic power stations is too long and the torque is too large, making it difficult to achieve the reflective lens angle adjustment. To this end, we provide a support structure for a photovoltaic power station concentrator 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 photovoltaic power station concentrating device with adjustable spacing.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] Example 1

[0033] See also Figure 1 、 Figure 2 、 Figure 7 、 Figure 11 and Figure 12 , which is the first embodiment of the present invention, provides a support structure for a photovoltaic power station concentrator device with adjustable spacing. By controlling the pitch bar 201a to move out at the lower end position of the support bar 101, the positioning assembly 200 and the adjustment assembly 300 are disconnected, and the reflective light assembly 400 can be moved to adjust the spacing between two adjacent groups of reflective light assemblies 400, so as to facilitate the adjustment of the air flow distance between the two groups of adjustment assemblies 300 according to actual needs. At the same time, the forward and backward movement of the progressive screw 304 is controlled, so that the progressive screw 304 will drive the locking plate 302 to rotate in both directions, thereby realizing the adjustment of the angle of the reflective light assembly 400 according to the position of the receiver, and realizing that a single person can perform the adjustment work and improving the adjustment efficiency.

[0034] Specifically, two groups of support assemblies 100 are symmetrically arranged front to back. The support assemblies 100 include support bars 101. A positioning assembly 200 is provided directly below each group of support assemblies 100. The positioning assembly 200 includes a positioning strip 201 connected to the lower end surface of the support bar 101 and a pitch bar 201a fixed to the upper end surface of the positioning strip 201. A plurality of adjustment assemblies 300 evenly distributed left to right are located between the two groups of support assemblies 100, and a reflective light assembly 400 for reflecting sunlight.

[0035] By setting up and using the above-mentioned structure, when it is necessary to adapt and adjust the spacing between two adjacent groups of reflective light components 400, the positioning strip 201 can be controlled to move downward, so that the positioning strip 201 is disconnected from the lower end surface of the support bar 101, and then the positioning strip 201 will drive the pitch bar 201a to move downward, so that the adjustment component 300 and the positioning component 200 are disengaged from the assembly relationship. At this time, the adjustment component 300 can be directly controlled to move a distance along the support bar 101, and then the movement of the adjustment component 300 will directly drive the position adjustment of the reflective light component 400. At the same time, when the adjustment component 300 is controlled to work, the adjustment component 300 will drive the rotation of the reflective light component 400, which can improve the adjustment efficiency.

[0036] according to Figure 2 、 Figure 3 and Figure 7The lower end surfaces of the struts 101 are each provided with a positioning opening 101c, and the pitch bars 201a are disposed in adjacent positioning openings 101c. The adjustment assembly 300 includes an assembly plate 301 located between the two sets of struts 101 and a locking plate 302 located directly above the assembly plate 301. A progressive screw 304 is disposed between the assembly plate 301 and the locking plate 302. The reflective light assembly 400 includes a reflective lens 401 connected to the locking plate 302 via bolts.

[0037] When using the above-mentioned structure, when controlling the movement of the pitch bar 201a, the pitch bar 201a is moved out of the positioning port 101c, thereby disengaging the pitch bar 201a from the connection with the adjustment assembly 300, and controlling the locking plate 302 and the assembly plate 301 to slide between the two sets of struts 101, thereby adjusting the distance between the two sets of reflective lenses 401, and at the same time controlling the progressive screw 304 to move in the front-to-back direction, and since the progressive screw 304 cannot rotate after being limited, the progressive screw 304 will control the locking plate 302 to rotate with the progressive screw 304 as the axis, and the locking plate 302 will drive the reflective lens 401 to adjust the angle, thereby improving the adjustment efficiency.

[0038] Further, according to Figure 3 and Figure 4 It can be seen that the two groups of struts 101 are fixed with mounting plates 103 on the side walls opposite to the reflective lens 401, and the two end faces of the lower surface of the mounting plates 103 are fixed with base frames 102. At the same time, the base frames 102 are connected to the ground through rivets, so that the struts 101 are supported by the base frames 102.

[0039] It should be noted that when installing the receiver, the receiver is installed directly above the entire device, with both ends of the receiver bolted to the mounting plate 103 through rods, and the mounting plate 103 then supports and stabilizes the receiver.

[0040] Example 2

[0041] See also Figure 3 、 Figure 4 and Figure 5 On the basis of Example 1, this embodiment uses the positioning spring 201c to facilitate the rapid reset of the positioning strip 201. At the same time, the connection rod 201b and the circular plate 202 are used in conjunction to disassemble the positioning strip 201 to achieve disassembly and assembly.

[0042] Specifically, connecting rods 201b are fixed to the upper end surfaces of the positioning strips 201 located on the left and right sides of the pitch bar 201a, and telescopic grooves 101b are provided at the positions of the upper end surfaces of the support bars 101 corresponding to the connecting rods 201b. The lower end surface of the support bar 101 is provided with a blocking hole 101d connected to the interior of the telescopic groove 101b, and the end surface of the connecting rod 201b passing through the blocking hole 101d is provided with a circular plate 202 connected to the inner wall of the telescopic groove 101b, and the lower end surface of the circular plate 202 is fixed with an assembly screw 202a spirally connected to the connecting rod 201b, and a positioning spring 201c is sleeved on the surface side of the connecting rod 201b inside the telescopic groove 101b, and the two ends of the positioning spring 201c are respectively in contact with the inner bottom surface of the telescopic groove 101b and the lower end surface of the circular plate 202.

[0043] When the positioning strip 201 is released, the positioning spring 201c pushes the circular plate 202 to move upward, thereby driving the connecting rod 201b to return to its original position, and thereby driving the positioning strip 201 to return to its original position, thereby controlling the pitch bar 201a to move out of the positioning port 101c. 1a moves back to the positioning port 101c. At the same time, when the entire positioning strip 201 needs to be disassembled, the circular plate 202 is rotated, thereby the circular plate 202 drives the assembly screw 202a to disengage from the upper end surface position of the connecting rod 201b, and then the connecting rod 201b can be directly moved out from the lower end position of the blocking hole 101d, and the positioning strip 201 can be removed from the lower end position of the support 101, so as to disassemble and replace the positioning assembly 200. When installing the positioning strip 201, the connecting rod 201b is inserted from the lower end position of the blocking hole 101d, and the connecting rod 201b is passed through the inside of the positioning spring 201c, and then the assembly screw 202a is threadedly connected to the connecting rod 201b, and the positioning strip 201 can be installed at the lower end surface position of the support 101.

[0044] Example 3

[0045] See also Figure 2 、 Figure 3 、 Figure 4 and Figure 6 Based on Example 1, this embodiment facilitates positioning or sliding of the adjustment component 300 through the engagement between the tooth block 303 and the pitch bar 201a.

[0046] Specifically, the opposing end surfaces of the two groups of struts 101 are each provided with a movable opening 101a that is connected to the interior of the positioning opening 101c. A circular frame strip 305 is fixed to the lower end surface of each group of assembly plates 301. Abutment blocks 305a that are in contact with the side surfaces of the adjacent struts 101 are fixed to the front and rear portions of the lower end surface of the circular frame strip 305. The end surfaces of the abutment blocks 305a near the struts 101 are bolted to tooth blocks 303 disposed inside the movable opening 101a, and the tooth blocks 303 are meshed with the corresponding pitch bars 201a.

[0047] By setting and using the above structure, since the tooth block 303 enters the positioning port 101c from the position of the moving port 101a, the tooth block 303 can be engaged with the tooth pitch bar 201a. When the positioning strip plate 201 controls the tooth pitch bar 201a to move downward in the positioning port 101c, the tooth pitch bar 201a is disengaged from the tooth block 303. Therefore, the circular frame bar 305 can be controlled to slide along the side position of the support bar 101. At the same time, the tooth block 303 and the abutment block 303 are engaged. 05a are bolted together, so the two can be disassembled to control the tooth block 303 and the abutment block 305a to be disconnected. Therefore, when the positioning strip plate 201 and the support bar 101 are disassembled, the tooth block 303 can also be taken out from the positioning port 101c, and at the same time, the two groups of support bars 101 are controlled to move in opposite directions away from each other, thereby controlling the abutment block 305a to move out of the moving port 101a, so that the circular frame bar 305 is taken out from the position between the two groups of support bars 101.

[0048] Example 4

[0049] See also Figure 6 、 Figure 7 、 Figure 9 and Figure 10 On the basis of Example 1, this embodiment uses the screw sleeve 302a and the progressive screw 304 to cooperate with each other to facilitate the angle adjustment of the locking plate 302.

[0050] Specifically, a strip cylinder 301a is fixed to the upper end surface of each assembly plate 301, and a progressive screw 304 passes through the inside of the corresponding strip cylinder 301a. The surface side wall of the progressive screw 304 is provided with two grooves 304b evenly distributed along the circumferential wall. The inner wall of each strip cylinder 301a is fixed with two convex strips 301c that slide in the grooves 304b respectively. The front and rear parts of the lower end surface of the locking plate 302 are fixed with threaded sleeves 302a, and the threaded sleeves 302a are spirally connected to the adjacent progressive screws 304. The upper end surfaces of the assembly plates 301 located on the left and right sides of the strip cylinder 301a are provided with arc-shaped holes 301b, and the left and right parts of the lower ends of the locking plates 302 located on the left and right sides of the strip cylinder 301a are fixed with arc rods 302b, and each arc rod 302b slides through the corresponding arc hole 301b respectively.

[0051] When the locking plate 302 is rotated, the arc rod 302b is driven by the locking plate 302 to slide in the arc hole 301b.

[0052] Example 5

[0053] See also Figure 7 and Figure 8 On the basis of Example 1, this embodiment pushes the movable strip 306 by the pushing spring 306e, so that the movable strip 306 stably pushes the friction block 306a to fit tightly with the handle 304a, thereby ensuring the stability of the forward and backward adjustment position of the handle 304a.

[0054] The cam 306a is fixed to the upper end of the movable plate 306, and the cam 306b is fixed to the upper end of the movable plate 306.

[0055] When the lever 304 is in the unlocked position, the spring 306e is released and the lever 306 is released, and the spring 306e is released to push the lever 306 back to its original position. The lever 304 is in the unlocked position, and the spring 306e is released and the lever 306 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever 304 is released, and the lever

[0056] When the movable strip plate 306 moves downward, the movable strip plate 306 will slide along the limiting rod 306d through the limiting hole 306b, and the limiting rod 306d will limit the position of the limiting hole 306b to ensure that the movable strip plate 306 moves stably in the circular frame bar 305. At the same time, the bolts between the connecting strip plate 306c and the circular frame bar 305 are unscrewed, and the distance between the movable strip plate 306 and the connecting strip plate 306c is shortened, so that the friction block 306a is moved to the end position of the circular frame bar 305, thereby the movable strip plate 306 can be pulled out from the inside of the circular frame bar 305, and the two are disassembled.
