Description

Technical Field

[0001] This utility model belongs to the field of solar thermal power generation, and specifically relates to an automatic parallelism adjustment mechanism for a parabolic trough collector. Background Technology

[0002] Parabolic trough solar thermal power generation systems convert solar radiation into heat energy through concentrating solar collectors. The design, manufacturing, and on-site assembly precision of the collectors significantly impact their optical efficiency, especially in terms of load bearing (primarily wind load) and torque transmission. High dimensional accuracy is required when installing parabolic trough collectors, particularly when the end plates at both ends of the collector frame are installed in series. The end plates are components that connect the collector frames together and transmit torque; the connection precision between the end plates and the collector frame, especially the parallelism of the reference datum, plays a crucial role in the assembly accuracy and efficiency of the end plates. During installation, in addition to ensuring vertical and horizontal positional accuracy, the parallelism and positional accuracy between the end plates and the reference datum of the collector frame must also be guaranteed.

[0003] Since solar collectors are typically large welded or riveted structures, ensuring parallelism solely through manufacturing precision is extremely difficult. Traditionally, there are two main methods to address this issue, but each has its limitations:

[0004] (1) After assembly, use a special instrument to measure the parallelism and then make adjustments until the requirements are met. This method has low assembly efficiency and is greatly affected by manual operation.

[0005] (2) An automatic parallelism adjustment mechanism is used for adjustment. One side uses a "V" shaped mechanism to cooperate with each other, and the other side uses a planar mechanism to cooperate with each other. However, this method has high requirements for the installation accuracy of the automatic adjustment mechanism components themselves, especially the perpendicularity, otherwise the accuracy of parallelism will be affected. Utility Model Content

[0006] To address the aforementioned problems in the prior art, this invention provides an automatic parallelism adjustment mechanism for a trough-type solar collector. This mechanism ensures that the collector frames automatically maintain parallelism during series installation, while also guaranteeing positional accuracy. Furthermore, it reduces the impact of human error and improves installation efficiency.

[0007] The main technical solution adopted in this utility model is as follows:

[0008] An automatic parallelism adjustment mechanism for a trough-type solar collector includes an adjustment assembly and a support assembly. The adjustment assembly is fixed to a shaftless end plate at one end of the solar collector frame, and the support assembly is fixed to a shafted end plate at the other end of the solar collector frame. The positioning end face at the bottom of the adjustment assembly and the positioning end face at the top of the support assembly are fitted together for positioning.

[0009] Preferably, the adjustment assembly includes two sets of support positioning blocks, which are symmetrically arranged on both sides of the shaftless end plate. The positioning end face of the support positioning block is provided with a positioning boss, which adopts a spherical structure and is used to cooperate with the support assembly for positioning.

[0010] Preferably, the support assembly includes an arc-shaped support block and a flat support block, and the arc-shaped support block and the flat support block are respectively installed on both sides of the shaft end plate for positioning in conjunction with the adjustment assembly. The positioning end face of the arc-shaped support block is provided with an arc-shaped groove, and the positioning end face of the flat support block is a flat structure.

[0011] Preferably, the spherical radius of the positioning boss is equal to the radius of the arc-shaped groove.

[0012] Preferably, the adjusting assembly is fixed to the shaftless end plate of the collector frame with rivets, and the supporting assembly is fixed to the shafted end plate of the collector frame with rivets.

[0013] Beneficial effects: This utility model provides an automatic parallelism adjustment mechanism for a trough-type solar collector, which has the following advantages:

[0014] (1) In this utility model, the adjustment assembly and the support assembly are positioned by spherical fit. Regardless of whether the parts are tilted during assembly, it does not affect the parallelism, thus eliminating the relatively complicated process of adjusting the parallelism of the collector and saving the installation cost of the collector.

[0015] (2) In this utility model, the two sets of support positioning blocks in the adjustment assembly do not have a left and right distinction, which can avoid errors during installation. At the same time, the arc surface support block and the flat support block in the support assembly can be installed with the support positioning block. There is no problem that the left and right installation positions cannot be used interchangeably. It has a foolproof function, no special installation requirements, and greatly improves the ease of installation, which greatly improves the installation efficiency of the solar collector.

[0022] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application. Example

[0023] An automatic parallelism adjustment mechanism for a trough-type solar collector, such as Figure 1 As shown, the device used to adjust the parallelism of the shafted end plate 2-2 and the shaftless end plate 2-1 when the collector frame 1 is connected in series includes an adjustment assembly 3 and a support assembly 4. The adjustment assembly 3 is fixed on the shaftless end plate 2-1 of the collector frame 1, and the support assembly 4 is fixed on the shafted end plate 2-2 of the collector frame 1. The positioning end face at the bottom of the adjustment assembly 3 and the positioning end face at the top of the support assembly 4 are matched and positioned for installation.

[0024] In this embodiment 1, as Figure 3 As shown, the adjustment assembly 3 includes two sets of support positioning blocks 3-1. The two sets of support positioning blocks 3-1 are symmetrically arranged on both sides of the shaftless end plate 2-1, and the positioning end face of the support positioning block 3-1 is provided with a positioning boss 3-2. The positioning boss 3-2 adopts a spherical structure and is used to cooperate with the support assembly 4 for positioning.

[0025] In this embodiment 1, as Figure 4-5 As shown, the support assembly 4 includes an arc-shaped support block 4-1 and a flat support block 4-2, which are respectively installed on both sides of the shaft-end plate 2-2 for positioning in conjunction with the adjustment assembly 3. The arc-shaped support block 4-1 has an arc-shaped groove 4-3 on its positioning end face, while the flat support block 4-2 has a flat positioning end face. Figure 2As shown, when the shaftless end plate 2-1 is assembled with the shafted end plate 2-2 of the collector frame 1, the spherical positioning boss 3-2 of the support positioning block 3-1 on one side of the shaftless end plate 2-1 is fitted into the arc groove 4-3 of the arc surface support block 4-1 on one side of the collector frame 1. The spherical positioning boss 3-2 of the support positioning block 3-1 on the other side of the shaftless end plate 2-1 is in contact with the plane of the plane support block 4-2. This automatically ensures the parallelism between the shaftless end plate 2-1 and the reference of the collector frame 1, and also ensures the positional accuracy in both the up, down, left, and right directions. Since the circular spherical surface of the positioning boss 3-2 is in the arc groove 4-3, regardless of the angle change, the center of the sphere never leaves the center line of the arc groove 4-3. Therefore, there is no requirement for whether the installation is tilted.

[0026] In this embodiment 1, the spherical radius of the positioning boss 3-2 is equal to the radius of the arc groove 4-3.

[0027] In this embodiment 1, the adjusting assembly 3 is fixed to the shaftless end plate 2-1 with rivets 5, and the supporting assembly 4 is fixed to the shafted end plate 2-2 with rivets 5.

[0028] The specific installation steps for this embodiment 1 are as follows:

[0029] S1: First, install the support positioning block 3-1 at the corresponding position of the shaftless end plate 2-1-1 of the collector frame 1 with rivets 5, and install it symmetrically on the left and right sides.

[0030] S2: Using the support positioning block 3-1 as the positioning of the shaftless end and the shaft with the shaft end as the positioning support of the shaft end, the three-point positioning at both ends is complete, and the installation of the solar collector frame 1 can be completed, and the entire solar collector frame 1 is assembled.

[0031] S3: Using the support positioning block 3-1 as the installation reference, the arc surface support block 4-1 and the flat support block 4-2 are respectively installed on the left and right sides of the shaft end plate 2-2 of the collector frame 1 by rivets 5 to ensure the relative position accuracy of them relative to the support positioning block 3-1.

[0032] S4: Position the support positioning block 3-1 according to... Figure 2 The assembly is carried out in the following manner: the end plate fasteners of the corresponding collector frame 1 are tightened, and the assembled collector frames 1 are connected in series one by one to complete the assembly.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
