Description

Technical Field

[0001] This utility model relates to a trough-type solar collector, and more particularly to a positioning and installation device for a trough-type solar collector. Background Technology

[0002] The positioning and installation device for parabolic trough solar collectors is mainly used for the precise installation and fixation of the collectors. It typically includes a base, bracket, and positioning adjustment mechanism, which can achieve precise positioning of the collector in terms of level and angle, ensuring that it is accurately facing the sun, improving solar energy capture efficiency, and providing a certain degree of stability and wind resistance.

[0003] A search revealed that application number 2020207152129 discloses a positioning and installation device for a parabolic trough solar collector. The device includes a positioning mechanism comprising a mounting plate and a front end plate, which are respectively fixed to both ends of the parabolic trough solar collector. The mounting plate has a first positioning hole, and the front end plate has a positioning pin fixedly connected to it. The mounting plate and the front end plate also have coaxial fixing holes. This invention effectively ensures the overall installation accuracy of the parabolic trough solar collector.

[0004] However, the aforementioned positioning and installation device requires removing each positioning device from the solar collector one by one when it is necessary to remove the solar collector, which is a rather troublesome, time-consuming and labor-intensive operation. Summary of the Invention

[0005] The purpose of this invention is to provide a positioning and installation device for a trough solar collector. It is easy to install, and when the collector body needs to be disassembled, simply pull the pull ring to move the moving rod to the left, which will release the lock on all collector bodies and improve disassembly efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A positioning and installation device for a trough-type solar collector is provided, including an installation shaft. A positioning groove is formed on the outer surface of the installation shaft. The number of positioning grooves is multiple. A spring groove is formed on the inner wall of the positioning groove. A spring is fixedly connected to the inner wall of the spring groove. A limit pin is fixedly connected to one end of the spring. A first moving block is fixedly connected to the lower surface of the limit pin. A first moving groove is formed at the bottom of the spring groove. A moving rod is provided inside the first moving groove. A second moving block is fixedly connected to the upper surface of the moving rod. The second moving block is located to the right of the first moving block. A solar collector body is arranged above the installation shaft. The number of solar collector bodies is multiple. A positioning block is fixedly connected to the lower surface of the solar collector body. The number of positioning blocks is multiple. The positioning block is located inside the positioning groove. A limit groove is formed on the side wall of the positioning block. The limit pin is located inside the limit groove.

[0007] Optionally, a pull ring is fixedly connected to the side wall of the movable rod, and the pull ring is located on the left side of the mounting shaft.

[0008] Optionally, a gear ring is fixedly connected to the outer surface of the mounting shaft, and there are multiple gear rings. A limit ring is also fixedly connected to the outer surface of the mounting shaft, and there are multiple limit rings.

[0009] Optionally, a mounting bracket is fitted onto the outer surface of the mounting shaft, and there are multiple mounting brackets located between adjacent gear rings and limiting rings.

[0010] Optionally, the inner wall of the mounting bracket is fixedly connected with a reinforcing rod, and the number of the reinforcing rods is multiple.

[0011] Optionally, a mounting block is fixedly connected to the outer wall of the mounting bracket. A second moving groove is formed on the upper surface of the mounting block. A threaded groove is formed at the bottom of the inner side of the second moving groove. A lead screw is threadedly connected to the inner surface of the threaded groove. A contact plate is fixedly connected to the upper surface of the lead screw. A locking pin is provided inside the mounting block. The locking pin is located above the contact plate. A turntable is fixedly connected to the lower surface of the lead screw.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model includes a solar collector body, a positioning block, a positioning groove, a limiting pin, a spring, a spring groove, a limiting groove, a pull ring, a moving rod, a second moving block, and a first moving block. When the solar collector body needs to be installed, the positioning block is aligned with the positioning groove, and then the solar collector body is moved downwards. This causes the edge of the positioning block to press against the inclined surface of the limiting pin, thereby moving the limiting pin to the left. The spring contracts until the limiting pin is fully inserted into the spring groove. At this point, the positioning block continues to move downwards until it can no longer move downwards and then stops. At this point, the spring rebounds. The limiting pin moves to the right, causing it to enter the limiting groove. At this point, the positioning block is locked and cannot be pulled out, indicating that the collector body is installed. To remove the collector body, simply pull the ring to the left, moving the moving rod to the left. This moves all the second moving blocks to the left, until the left side of the second moving block contacts the right side of the first moving block. This then moves all the first moving blocks and the limiting pin to the left until the moving rod can no longer be pulled. At this point, the limiting pin disengages from the limiting groove, and the entire collector body can be removed. This invention is easy to install. When disassembling the collector body, simply pull the ring to move the moving rod to the left to release the locking of all collector bodies, improving disassembly efficiency.

[0014] This utility model includes a collector body, a mounting shaft, a turntable, a lead screw, a contact plate, a locking pin, and a gear ring. Since the curved surface of the collector body needs to face the sunlight, the orientation of the curved surface must be adjusted according to the direction of sunlight. This requires rotating the mounting shaft, which in turn rotates the turntable, causing the lead screw and contact plate to rotate. This controls the downward movement of the turntable, lead screw, and contact plate, allowing the locking pin to move downward under gravity. Once the locking pin disengages from the gear ring, the mounting shaft can be rotated. After the collector body rotates to the appropriate angle, the turntable is rotated in the opposite direction, causing the turntable, lead screw, and contact plate to move upward. This causes the locking pin to move upward, making contact with the gear ring. The locking pin is located in the tooth groove of the gear ring, at which point the gear ring is locked, preventing the mounting shaft from rotating, and thus preventing the collector body from rotating. This completes the angle adjustment of the collector body. Attached Figure Description

[0025] Reference Figure 1-4The present invention will now be described. A positioning and installation device for a trough-type solar collector includes a mounting shaft 1. The outer surface of the mounting shaft 1 has multiple positioning grooves 2. The inner wall of each positioning groove 2 has a spring groove 3. A spring 4 is fixedly connected to the inner wall of the spring groove 3. One end of the spring 4 is fixedly connected to a limit pin 5. A first moving block 6 is fixedly connected to the lower surface of the limit pin 5. A first moving groove 7 is formed at the bottom of the spring groove 3. A moving rod 8 is installed inside the first moving groove 7. A second moving block 9 is fixedly connected to the upper surface of the moving rod 8, located to the right of the first moving block 6. A collector body 10 is positioned above the mounting shaft 1. Multiple collector bodies 10 are included. Multiple positioning blocks 11 are fixedly connected to the lower surface of each collector body 10. The positioning blocks 11 are located inside the positioning grooves 2. A limit groove 12 is formed on the side wall of each positioning block 11, and the limit pin 5 is located inside the limit groove 12. When installing the collector body 10, the positioning blocks 11 are aligned with the positioning grooves 2 and then lowered. Moving the collector body 10 causes the edge of the positioning block 11 to press against the inclined surface of the limiting pin 5, thereby moving the limiting pin 5 to the left. The spring 4 contracts until the limiting pin 5 is fully engaged in the spring groove 3. The positioning block 11 continues to move downwards until it stops. At this point, the spring 4 rebounds, causing the limiting pin 5 to move to the right, so that the limiting pin 5 enters the limiting groove 12. The positioning block 11 is now stuck and cannot be pulled out, thus completing the installation of the collector body 10. To remove the collector body 10, simply pull the pull ring 24 to the left, causing... The moving rod 8 moves to the left, thereby driving all the second moving blocks 9 to move to the left. The left side of the second moving block 9 contacts the right side of the first moving block 6, which will drive all the first moving blocks 6 and the limiting pin 5 to move to the left until the moving rod 8 can no longer move. At this time, the limiting pin 5 disengages from the limiting groove 12, and the entire collector body 10 can be removed. Disassembly is convenient. A pull ring 24 is fixedly connected to the side wall of the moving rod 8. Pulling the pull ring 24 can drive the moving rod 8 to move. The pull ring 24 is located on the left side of the mounting shaft 1.

[0026] The present invention provides a positioning and installation device for a trough-type solar collector. Compared with the prior art, it is easy to install. When it is necessary to disassemble the collector body 10, simply pull the pull ring 24 to move the moving rod 8 to the left, which can release the lock on all collector bodies 10, thus improving the disassembly efficiency.

[0027] Please refer to another embodiment of this utility model as well. Figures 1 to 4A gear ring 13 is fixedly connected to the outer surface of the mounting shaft 1. Multiple gear rings 13 are also fixedly connected to the outer surface of the mounting shaft 1. A limiting ring 14 is fixedly connected to the outer surface of the mounting shaft 1. The gear rings 13 and the mounting block 17 cooperate to allow the mounting shaft 1 to rotate more effectively on the mounting bracket 15. Multiple limiting rings 14 are also present. A mounting bracket 15 is fitted onto the outer surface of the mounting shaft 1, providing support for the present invention. Multiple mounting brackets 15 are located between adjacent gear rings 13 and limiting rings 14. A reinforcing rod 16 is fixedly connected to the inner wall of the mounting bracket 15, improving its supporting force and load-bearing capacity. Multiple reinforcing rods 16 are also present. A mounting block 17 is fixedly connected to the outer wall of the mounting bracket 15. A second moving groove 18 is formed on the upper surface of the mounting block 17. A threaded groove 19 is formed at the bottom of the inner part of the second moving groove 18. A lead screw 20 is threadedly connected to the inner surface of the threaded groove 19. A lead screw 20 is fixedly connected to the upper surface of the lead screw 20. There is a contact plate 21, and a locking pin 22 is provided inside the mounting block 17. The locking pin 22 is located above the contact plate 21. Since the arc surface of the collector body 10 needs to face the sunlight, the orientation of the arc surface of the collector body 10 needs to be adjusted according to the direction of sunlight. That is, the mounting shaft 1 needs to be rotated, which can rotate the turntable 23 to drive the lead screw 20 and the contact plate 21 to rotate, thereby controlling the turntable 23, lead screw 20 and contact plate 21 to move downward, so that the locking pin 22 moves downward under the action of gravity. When the locking pin 22 engages with the gear ring 13... After disengagement, the mounting shaft 1 can be rotated. After the collector body 10 is rotated to a suitable angle, the turntable 23 is rotated in the opposite direction, which drives the turntable 23, the lead screw 20 and the contact plate 21 to move upward, thereby driving the locking pin 22 to move upward, and then making the locking pin 22 contact the gear ring 13. The locking pin 22 is located in the tooth groove of the gear ring 13. At this time, the gear ring 13 is locked, the mounting shaft 1 cannot rotate, that is, the collector body 10 cannot rotate, thus completing the angle adjustment of the collector body 10. The turntable 23 is fixedly connected to the lower surface of the lead screw 20.
