Description

Technical Field

[0001] This utility model relates to the field of photothermal mirror field support installation technology, specifically, to a photothermal mirror field positioning component. Background Technology

[0002] Currently, there are more and more solar thermal power projects in power construction. The working efficiency of a solar thermal power plant mainly depends on the solar thermal efficiency of the mirrors and collectors. High solar thermal efficiency can ensure high lava temperature, and high lava temperature also means high power generation efficiency of the unit. Therefore, the installation accuracy of the mirrors and supports in the mirror field of a solar thermal power plant project is of paramount importance to a solar thermal unit.

[0003] Due to the high precision requirements and large workload involved in the construction of pile caps and the installation of pre-embedded bolts for solar thermal mirror fields, the construction of such fields requires high-precision processes. For example, a 4MW unit typically has approximately 9,500 mirrors, each requiring a pile foundation with four anchor bolts to secure the mirror and support. This results in 9,500 * 4 = 38,000 pile cap bolts to be installed, with an installation accuracy controlled within 5mm. Currently, the construction of pile caps and the installation of pre-embedded bolts in solar thermal mirror fields for power generation projects present several challenges, including significant deviations in bolt accuracy and difficulty in height adjustment. Considering that the installation accuracy of the mirrors and supports directly impacts the power generation efficiency of the solar thermal project, existing technologies typically employ calibration procedures to control the overall quality of the pile cap bolts. However, this approach increases the number of steps, reduces efficiency, and raises labor costs. Utility Model Content

[0032] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0033] Example:

[0034] Please see Figures 1-4 This embodiment provides a photothermal mirror field positioning component, including a pile cap template 1 and a positioning plate 2 set on the ground part, and a fixing plate 3 set on the underground part. The pile cap template 1, the positioning plate 2 and the fixing plate 3 are arranged sequentially from top to bottom and connected by pile cap bolts 4.

[0035] In one specific embodiment, the pile cap template 1 includes a template body 101, and a template connection structure 102 is provided on the outer side of the template body 101. The template body 101 and the template connection structure 102 are integrally formed. The template connection structure 102 has evenly distributed connection holes 105 that match the pile cap bolts 4. The positioning plate 2 has positioning holes 201 that match the connection holes 105. The fixing plate 3 has fixing holes 301 that match the positioning holes 201. The fixing plate 3 and the pile cap bolts 4 are respectively fixedly connected to the reinforcing cage 5 located underground. Five nuts are also threaded on the outer side of the pile cap bolts 4. One nut is located inside the reinforcing cage 5 and is fixed to the reinforcing bars inside the reinforcing cage 5. The fixed connection is used for adjusting the height of the pile cap bolt 4. It is a non-removable nut. Two nuts are set on the upper and lower sides of the fixing plate 3 and fixedly connected to the reinforcing cage 5. They are used to clamp the fixing plate 2. They are non-removable nuts. Two nuts are set on the upper and lower sides of the positioning plate 2. They are used to clamp the positioning plate 3. They are detachable nuts. Preferably, multiple lifting parts 103 are evenly distributed on the outer side of the template body 101. They not only facilitate the lifting of the pile cap template 1, but also serve as reinforcing ribs to strengthen the template body 101. The lifting parts 103 are provided with lifting holes 104 for easy lifting. The positioning plate 2 is provided with a first through hole 202 and the fixing plate 3 is provided with a second through hole 302, which saves costs.

[0036] In an optional embodiment, the positioning assembly includes a pile cap template 1, a positioning plate 2, a fixing plate 3, and a pile cap bolt 4.

[0037] In this embodiment, the pile cap template 1 is provided with fixing holes at the four corners, and the size of the fixing holes is between 10mm and 25mm. The pile cap template 1 is made of 2mm carbon steel plate, and can be split in half and connected by M20*20 bolts to splice it into one piece. The height is 40cm, which meets the construction requirements of general and special pile caps, and can be reused.

[0038] In this embodiment, the positioning plate 2 is made of 4mm iron plate, and the material is carbon steel. The model is 505*620*10mm (or depending on the actual size). There is a 6mm diameter round hole in the middle, which is used to align the center point. There are holes with an inner diameter of 36mm at the four corners for positioning the four pile cap bolts 4. The positioning plate 2 is fixed with the pile cap bolts 4 by using a nut clamping method.

[0039] In this embodiment, the fixing plate 3 is made of 4mm iron plate, and the material is carbon steel. The size is 505*620*10mm, which is the same as the size of the positioning plate 2. There is a 6mm diameter round hole in the middle, which is used to find the center point. There are holes with an inner diameter of 36mm at the four corners for the initial fixing of the pre-embedded pile cap bolts 4. The fixing plate 3 is welded to the upper part of the reinforcing cage 5 as required. This is non-removable and will be poured into the pile cap concrete later as a permanent reinforcement to improve the installation strength of the pre-embedded pile cap bolts 4.

[0040] In this embodiment, the pile cap bolt 4 has a diameter of 36mm and a length of 80cm, which meets the installation requirements of the mirror and bracket. Each pile cap bolt 4 is equipped with five nuts. The bottom nut is welded to the internal steel bars of the steel cage 5 and is used for height adjustment after the positioning plate 2 is installed. The second and third nuts from the bottom are mainly used to clamp and fix the plate 3, and the fourth and fifth nuts from the bottom are mainly used to clamp and fix the positioning plate 2. The first, second and third nuts are non-removable bolts. After all the work is measured, fixed and positioned, a comprehensive welding reinforcement is carried out to prevent the displacement problem during the subsequent pouring process.

[0041] In this embodiment, to facilitate the construction of the pile cap and the reinforcement of the pile cap bolt 4, the pile cap bolt 4 and the fixing plate 3 are non-removable parts. To permanently reinforce the pre-embedded pile cap bolt 4, both components remain within the pile cap. This provides a strong guarantee for the subsequent installation of the mirror support in the mirror field.

[0042] The usage of this photothermal mirror field positioning component is as follows:

[0043] First, prepare the positioning components before construction, and check all accessories, such as five nuts for each of the four bolts, positioning plate 2, fixing plate 3, pile cap template 1, etc. After ensuring all accessories are complete, consider that this tool is only suitable for ground pile cap construction. Therefore, the underground part is where the early pile foundation construction and pouring work has been completed, and the reinforcing cage 5 has been welded or tied.

[0044] To begin work within the scope of this tool, first, place the four pile cap bolts 4 in appropriate positions. Place the fixing plate 3 on top of the reinforcing cage 5. Based on the center point on the fixing plate 3 and the center positions of the four bolt holes, position and spot weld the fixing plate 3. After positioning, the pile cap bolts 4 pass through the four holes of the fixing plate 3. Now, begin the initial fixing of the pile cap bolts 4. Weld the bottom nut of the five nuts on the pile cap bolt 4 to the reinforcing cage 5 (adjust the appropriate height before welding). The second and third nuts are initially installed on the upper and lower parts of the fixing plate 3. At this point, the pile cap bolts 4 need to be positioned according to latitude, longitude, and height. After positioning, tighten the upper and lower nuts of the fixing plate 3 to initially fix the pile cap bolts 4. Finally, install the positioning plate 2 for positioning. At this point, the latitude, longitude, and height need to be checked again. After final positioning, tighten the two nuts on the top and bottom of the positioning plate 2 to secure it again. Finally, weld the bottom nut of the pile cap bolt 4 to the pile cap bolt 4. Weld the two nuts on the top and bottom of the fixing plate 3 to the pile cap bolt 4 and the fixing plate 3 for final reinforcement. At this point, the installation, positioning and reinforcement of the pile cap bolt 4 is complete. Before pouring the pile cap, with the center of the positioning plate 2 as the center, install the pile cap template 1 around the perimeter and place it on a flat ground outside the pile cap. Reinforce the template with short steel bars and iron pegs driven into the ground. Finally, pour the concrete into the steel cage 5 and the pile cap template 1 to the required height to complete the work. The concrete will gradually solidify and gain strength over time. Finally, remove the pile cap template 1, the positioning plate 2, and the two nuts on the top and bottom of the positioning plate 2. At this point, the work is complete.

[0045] This utility model solves the problems of difficulty in controlling accuracy and wasting manpower and time during the installation of mirror supports in the solar thermal power project. Through practical implementation, it achieves the requirements of standardization, safety, convenience and efficiency. It is conducive to improving the construction quality and accuracy of the mirror field pile cap construction and the pile cap pre-embedded bolt construction process, avoiding rework problems, and further promoting the construction progress.
