DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the utility model more clear and explicit, the technical scheme of the utility model will be described clearly and completely below in combination with the drawings.

[0019] In order to realize the national "double carbon" strategic goal, the new energy power generation industry gradually advances to the tower type light heat, and compared with other types of light heat projects, the heliostat is the main component of the tower type light heat. The heliostat can mainly concentrate and reflect sunlight to the tower end receiver, thereby improving the utilization rate of solar energy. Therefore, the fixation of the heliostat is particularly important, but due to the huge number of heliostats and the high exposure of the heliostat column to the ground (1.5-3 meters), the underground part needs to be guided and poured with concrete for fixation, which requires accurate positioning of the column before pouring and ensures that no displacement deviation occurs during the pouring process.

[0020] In the related art, the steel column of the heliostat is fixed by using a steel column triangular support at the initial stage of construction. Due to the influence of concrete pouring and vibration during the construction process, the steel column may be displaced or tilted after the completion of the construction, which may result in the quality problem that the center coordinates of the steel column cannot meet the design requirements, and the construction progress is seriously affected, the construction difficulty is increased, unnecessary economic losses are caused, and the pile foundation construction progress of the overall photovoltaic power generation project is affected.

[0021] In order to achieve the above purpose, the utility model provides a heliostat column temporary support device 100, which comprises a fixing part 10, a plurality of adjusting legs 30 and a horizontal calibration part 50, as shown in Figure 1 and Figure 2 The fixing part 10 is provided with a fixed channel 10A in the middle to be sleeved on the heliostat column 200, the plurality of adjusting legs 30 are spaced and rotatably arranged on the outer periphery of the fixing part 10, and the axial direction of each adjusting leg 30 is arranged at an angle with the axial direction of the fixing part 10.

[0022] The temporary support device 100 for a heliostat column in the present invention includes a fixing member 10, multiple adjustment legs 30, and a horizontal calibration member 50. The fixing member 10 has a central fixed channel 10A for mounting on the heliostat column 200. Multiple adjustment legs 30 are rotatably arranged at intervals around the outer periphery of the fixing member 10, with each adjustment leg 30 axially positioned at an angle to the fixing member 10. The use of multiple adjustment legs 30 in conjunction with the fixing member 10 effectively ensures column stability during construction, ensuring that the column's verticality and center position remain unchanged during concrete pouring, thereby increasing the success rate of construction. The horizontal calibration member 50 is mounted on the top surface of the fixing member 10. The adjustment legs 30 are axially adjustable, allowing them to move up and down along the axis, allowing for fine-tuning of the column. By observing the horizontal calibration member 50 mounted on the fixing member 10 to indicate a horizontal position, the length of the fixed legs relative to the fixing member 10 is adjusted to ensure that the column's center position and verticality meet the requirements, ensuring that the column is within the allowable deviation range, ensuring construction quality, and facilitating concrete pouring.

[0023] Optionally, the horizontal calibration member 50 is a circular vial.

[0024] In this embodiment, it is important to note that direct contact between concrete, vibrating rods, and the like with the heliostat column 200 is strictly prohibited during the concrete pouring process. When the heliostat column 200 is installed within the fixing channel 10A of the fixing member 10, the axial direction of the heliostat column 200 is perpendicular to the top surface of the fixing member 10. The horizontal calibration member 50 is a circular vial mounted on the top surface of the fixing member 10. During the pouring process, the circular vial is constantly monitored to ensure that it is centered, ensuring that the heliostat column 200 is within the allowable deviation range and guaranteeing construction quality.

[0027] Optionally, the buffer member 13 is a rubber or silicone member, which is adhered to the inner wall of the clamping clamp 11, or fixed to the inner wall of the clamping clamp 11 by bolts or pins. The rubber or silicone member has a certain degree of elasticity, which can reduce shock or cushion the contact between the two rigid structures, effectively protecting the contact parts from scratches or extrusion damage.

[0028] Optionally, the clamping hoop 11 comprises a fastener 111 and two semicircular pieces 113, one end of the two semicircular pieces 113 is hingedly connected, and the other end is respectively provided with a connecting part 1131, and the fastener 111 is used to threadedly lock the two connecting parts 1131.

[0029] In this embodiment, one end of the two semicircular pieces 113 is rotationally connected so that the other semicircular piece 113 can be opened and closed, facilitating the assembly of the fixing member 10 and the heliostat stand 200. The fastener 111 can be a bolt, and the end portions of the two semicircular pieces 113 are provided with connecting parts 1131 in a circumferential radial direction, the two connecting parts 1131 are oppositely arranged in the closed state of the semicircular piece 113, and the two connecting parts 1131 are each provided with a connecting hole, one end of the bolt is arranged through one connecting part 1131 and limited thereon, and the other end is arranged through the other connecting part 1131 and threadedly connected with the connecting hole of the connecting part 1131 to lock the two semicircular pieces 113.

[0030] Further, each semicircular piece 113 has a horizontal part and a clamping part, and the horizontal part and the clamping part are integrally formed and the horizontal part is perpendicularly arranged relative to the clamping part. The fixing channel 10A is formed in the clamping part for clamping and limiting the heliostat stand 200, the axial direction of the heliostat stand 200 is perpendicular to the horizontal part, and the horizontal alignment member 50 is installed on the horizontal part to observe whether the circular level bubble is centered at any time during pouring to ensure that the heliostat stand 200 is within the allowable deviation range and to ensure construction quality.

[0031] Further, the clamping hoop 11 of the fixing member 10 described above adopts a light aluminum alloy structure, is convenient to carry, has a simple structure and is easy to operate, improves work efficiency, and the inside of the clamping hoop 11 is lined with a layer of soft rubber material, which on the one hand effectively protects the zinc plating layer of the heliostat stand 200 from being scratched, and on the other hand increases the friction force, which can better fix the heliostat stand 200.

[0032] Optionally, the adjusting leg 30 comprises a support body 31, a hinge piece 33 located at one end of the support body 31, and a telescopic piece 35 located at the other end of the support body 31, the other end of the hinge piece 33 is connected with the fixing member 10, and the telescopic piece 35 is movably connected with the support body 31 to adjust the total length of the support body 31 and the telescopic piece 35 along the axial direction of the support body 31.

[0033] In the embodiment, the adjusting leg 30 is connected with the fixing member 10 by the hinge 33, and the angle between the axial direction of the supporting body 31 and the axial direction of the fixing member 10 can be adjusted, that is, the angle between the axial direction of the supporting body 31 and the axial direction of the heliostat stand 200 can be adjusted, so that the fixing member 10 is adjusted to be horizontal, and the axial direction of the heliostat stand 200 is perpendicular to the ground.

[0034] Specifically, the adjustment of the angle can greatly adjust the levelness of the fixing member 10, and then the length of the supporting body 31 and the telescopic member 35 are adjusted to finely adjust the levelness of the fixing member 10. The levelness of the fixing member 10 can be adjusted in real time by observing the horizontal calibration member 50, so that the top surface of the fixing member 10 reaches the horizontal standard. Then, the total length of the supporting body 31 and the telescopic member 35 is adjusted, so that the center position and the perpendicularity of the stand meet the requirements, the deviation range of the stand is ensured, the construction quality is ensured, and the concrete pouring work is facilitated.

[0035] Optionally, the hinge 33 is a rotary damping hinge, so that the supporting body 31 is rotated relative to the fixing member 10 and then is limited in angle by damping, so that the horizontal positioning of the fixing member 10 is realized.

[0040] The specific operation of using the heliostat column temporary support device 100 of the utility model is as follows:

[0041] The installation of the heliostat column 200 (hereinafter referred to as the column) is to fix a part of it on the ground. First, a hole is drilled to an appropriate depth, and a sufficient gap for concrete pouring is reserved. The column is inserted into the hole through hoisting equipment. After rough adjustment is made by using a line rope and other tools, the column position and perpendicularity are basically appropriate. Then, the temporary support device 100 is adjusted to an appropriate height, and the clamping hoop 11 of the fixing part 10 is connected with the column. The hoop is fastened on the column by two semicircular parts through bolts. A rubber ring with buffering function is designed in the hoop.

[0042] The adjusting leg 30 is connected with the clamping hoop 11 through hinging, and can be rotated and folded for convenient carrying. The exposed section 353 at the end of the adjusting leg 30 is designed in a conical shape. The bottom of the adjusting leg 30 is pressed into the soil body with force to ensure that the whole support is stable and will not fall down.

[0043] The column is finely adjusted by the hoisting machinery, and the telescopic part 35 of the adjusting leg 30 is moved up and down relative to the support main body 31 by adjusting and leveling the bolt 37. After the circular level bubble on the horizontal ring of the clamping hoop 11 is observed to be in the center, the leveling bolt 37 is tightened. At this time, the center position and perpendicularity of the column meet the requirements, and concrete pouring work can be carried out. During the concrete pouring process, concrete and vibration rods should not be directly contacted with the column. The circular level bubble is observed at any time during the process to ensure that the column is within the allowable deviation range and the construction quality is ensured.
