Description

Technical Field

[0001] The present invention relates to the technical field of heat collector installation methods, and in particular to an assembly method for a super-large wide slot heat collector. Background Art

[0002] A method for hoisting and positioning a trough solar collector disclosed in the prior art with the publication number "CN111559702B" includes: S1, hoisting the first two trough solar collectors; S2, hoisting the remaining trough solar collectors; S3, adjusting and connecting the trough solar collectors. When hoisting the trough solar collectors, all the trough solar collectors are positioned at the center position by cooperating with the positioning shaft and the positioning hole, and then the orientation of the trough solar collector is adjusted. When the tower scales suspended in the symmetrical structural positions on the cantilevers on the left and right sides of the trough solar collector are aligned with the indicated readings of the level, it means that the trough solar collectors are just facing upward. After all the trough solar collectors are conveniently adjusted to face upward, the adjacent trough solar collectors can be fixedly connected together.

[0003] However, the above-mentioned trough-type solar collector hoisting and positioning method still has obvious defects during use: the above-mentioned collector is assembled through positioning shafts and positioning holes, but the assembly method before the shaft hole has not been pre-positioned. Therefore, each part needs to be positioned through the shaft-hole matching method during the assembly process. Because the shaft-hole matching process needs to be constantly debugged, this installation method directly leads to low assembly efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0040] See also Figure 1-6 , the present invention provides a technical solution:

[0041] Example 1:

[0042] A method for assembling an ultra-wide slot solar collector, comprising:

[0043] S1: Provide a plurality of cantilever frames 1 and corresponding columns 2. The columns 2 are fixed to the mounting base 3 provided at the upper end of the cantilever frames 1 by bolts. A series hole 4 is provided on each of the cantilever frames 1 and the columns 2.

[0044] S2: providing a series cross frame 5, and passing the series cross frame 5 through the series holes 4 to complete the series connection of the cantilever frames 1 and the columns 2 to form a supporting truss 6;

[0045] S3: Provide a pair of end frames 7, which are fixedly mounted on both sides of the supporting truss 6;

[0046] S4: Provide a plurality of cantilevers 8, which are fixedly mounted on both sides of the cantilever frame 1; wherein,

[0047] Laser positioning holes 9 are provided on the end frame 7 and the cantilever 8. The laser beam emitted by the laser emitter 15 passes through the serial hole 4 or the laser positioning hole 9 for pre-positioning before the subsequent installation steps; what is different from the prior art is that the related linearly arranged components in the prior art usually adopt an axial hole matching method. Since the axial hole connection in the component is usually multiple, it is necessary to continuously adjust during the axial hole matching process so that multiple axial holes can match smoothly. In the present invention, a laser emitter 15 is used to pre-position the serial holes 4 or the laser positioning hole 9. The laser emitter 15 in this embodiment can emit an annular point-shaped laser beam. The diameter of the annular laser beam is adjusted according to the size of the serial hole 4 or the laser positioning hole 9. If, during the assembly of multiple components, part of the laser beam cannot pass through the serial hole 4 or the laser positioning hole 9 smoothly, the worker is prompted to make manual adjustments. In summary, when multiple serial holes 4 or laser positioning holes 9 can pass through the laser beam smoothly, the matching is completed, and welding or screwing is performed at this time. The bolt is fixed, and the passage of the laser beam is observed during the fixing process to pay attention to the position changes of the components. In addition, the serial holes 4 in this embodiment can not only be positioned, but also the serial cross frame 5 is installed after the positioning is completed, so as to quickly complete the serial connection of multiple linearly arranged components. Compared with the one-to-one axis hole matching method, the assembly accuracy and assembly efficiency are improved. In order to ensure the assembly accuracy between multiple cantilever frames 1, the serial holes 4 on the cantilever frame 1 are respectively arranged at the left and right ends and the bottom position of the frame structure. Through the positioning of the three serial holes 4, the alignment accuracy between the frame structures of multiple groups of linearly arranged cantilever frames 1 can be guaranteed. In addition, the serial holes 4 on the column 2 are arranged at the bottom position of the central axis of the column 2. The serial holes 4 set here and the subsequent installation of the serial cross frame 5 will not affect the installation of the adjustable mirror panel assembly 10, and will not hinder its light reception. In order to further fix the linearly arranged cantilever frames 1, after the spacing is determined, the auxiliary support frame 14 is used to further ensure the structural strength and ensure the firmness of the connection between adjacent cantilever frames 1;

[0048] S5: providing a plurality of sets of adjustable mirror panel assemblies 10 and installing the plurality of adjustable mirror panel assemblies 10 on the support truss 6. The adjustable mirror panel assemblies 10 can fine-tune the reflection position of light by changing the curvature of their own arc surface, thereby ensuring that the heat collecting tubes 12 can maximize the use of reflected light energy;

[0049] S6: Provide a pair of rotating support frames 11, and fix the rotating support frames 11 to the side away from the end frame 7. In this embodiment, the rotating support frames 11 are provided with a rotating reduction mechanism fixedly connected to the end frame 7, and the rotation of the supporting truss 6 and its connecting structure is driven by the operation of the rotating reduction mechanism; and

[0050] S7: Provide a plurality of heat collecting tubes 12 , and weld and fix the plurality of heat collecting tubes 12 on the columns 2 .

[0051] The steps of inserting the series cross frame 5 into the series hole 4 for series installation are specifically as follows:

[0052] Lift several cantilever frames 1 in turn, place them on the auxiliary seat, and pre-position them by passing the laser beams emitted by three laser emitters 15 through the three serial holes 4 on the cantilever frame 1 at the same time. After positioning is completed, use the serial cross frame 5 to pass through the serial holes 4 on the cantilever frame 1, and make the adjacent cantilever frames 1 equidistant by measurement. After adjustment is completed, the cantilever frame 1 and the serial cross frame 5 are fixed by welding. Then, lift several columns 2 in turn, and pre-position them by passing the laser beams emitted by the laser emitter 15 through the serial holes 4 on the column 2. After positioning is completed, fix the column 2 and the cantilever frame 1 by bolting, and then insert the serial cross frame 5 into the serial hole 4 of the column 2, and fix the serial cross frame 5 to the column 2 by welding.

[0053] The steps of fixing and installing the end frames 7 on both sides are specifically as follows:

[0054] The end frame 7 is lifted to both ends of the assembled support truss 6 so that the laser beam emitted by the laser emitter 15 passes through the laser positioning holes 9 opened on the front and rear ends of the end frame 7 at the same time. The number of laser positioning holes 9 opened on the end frame 7 is not less than 2. After the positioning is completed, the end frame 7 is fixedly installed on both ends of the support truss 6 by welding.

[0055] The steps of fixing and installing the cantilevers 8 on both sides are as follows:

[0056] Lift the cantilevers 8 on both sides to the two ends of the supporting truss 6, and make the laser beam emitted by the laser emitter 15 pass through the laser positioning holes 9 opened on the cantilever 8. The number of laser positioning holes 9 opened on the cantilever 8 is not less than 2 and is distributed at least at both ends of the cantilever 8. After the positioning is completed, the cantilever 8 is fixed on the side arm 16 of the cantilever frame 1 by welding.

[0057] Example 2:

[0058] The plurality of adjustable mirror panel assemblies 10 provided in this embodiment include a mirror panel 17, an elastic traction member 18, and a rotating traction roller 19. The specific installation steps are as follows:

[0059] A mirror panel 17 is provided, and a plurality of traction links 13 are movably provided on the back side of the mirror panel 17, and an elastic traction member 18 cooperating with the traction link 13 is installed on the cantilever 8. The elastic traction member 18 in this embodiment includes a spring seat, a traction spring, and a screw seat fixedly installed at one end of the traction spring away from the spring seat. A threaded hole is opened on the screw seat, and both ends of the traction link 13 are opened with external threads. The two ends of the traction link 13 are movably mounted on the back side of the mirror panel 17 and the screw seat connected to the traction spring through the opened external threads. The elastic force generated by the traction spring pulls the mirror panel 17 to form an arc bend, so that the light energy is reflected to the heat collecting tube 12 by the bending of the mirror panel 17. Since the above structure is a common connection structure in the prior art, it will not be described in detail here.

[0060] Provide a plurality of rotating traction rollers 19, which are fixedly mounted at both ends of the cantilever 8, and place the mirror plate 17 on the rotating traction rollers 19, and form a curved surface structure by pulling the traction link 13 at the bottom of the mirror plate 17;

[0061] A rotating traction roller 19 is provided, and the flexible traction belts 20 on both sides of the mirror plate 17 are respectively wound around the rotating traction roller 19 provided on the same side. The rotating traction roller 19 changes the curvature of the arc surface of the mirror plate 17 by rotating;

[0062] The mirror panel 17 is mounted on both ends of the rotating traction roller 19 and is also connected to a flexible traction belt 20. The flexible traction belt 20 serves as a transition structure connecting the mirror panel 17 and the rotating traction roller 19. The rotation of the rotating traction roller 19 and the coordinated action of the elastic traction member 18 can achieve fine adjustment of the curvature of the mirror panel 17.

[0063] The steps of installing the provided rotating traction roller 19 on the cantilever 8 are as follows:

[0064] The provided rotating traction roller 19 is provided with a penetrating laser positioning hole 9, so that the laser beam emitted by the laser emitter 15 passes through the laser positioning hole 9 provided on the rotating traction roller 19 and is then welded and fixed. The rotating traction rollers 19 are installed one by one using this method.

[0065] A plurality of curvature adjustment motors are also provided, which are arranged in a one-to-one correspondence with the rotating traction rollers 19. The curvature adjustment motors are fixedly connected to the axis of the rotating traction rollers 19 through coupling sleeves.

[0066] The laser emitter 15 can ensure the consistency of the installation positions of the plurality of rotating traction rollers 19 . The precise installation of the rotating traction rollers 19 is related to the consistency of the subsequent curvature adjustment of the mirror plate 17 .

[0067] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
