Description

Technical Field

[0001] The present application relates to the technical field of heliostat pipe pile construction technology, and in particular to an energy-saving rapid installation device for heliostats in tower-type solar thermal power stations. Background Art

[0002] Heliostat refers to an optical device that reflects light from the sun or other celestial bodies in a fixed direction. The solar thermal site covers a vast area and the construction period is short. A 100MW solar thermal power station requires the installation of 16,000 heliostats.

[0003] In the related art, before hoisting the heliostats, a plurality of stacked heliostats need to be transported to the construction site by a transport vehicle, and then the two ends of the heliostats are connected by a hoisting rope, and finally the heliostats are fixed by a hoisting device and the hoisting rope to be hoisted.

[0004] With regard to the above-mentioned related technologies, since the heliostat may be tilted when placed on a transport vehicle, it is necessary to adjust the length of the lifting rope during the lifting process to ensure that the heliostat is in a balanced state. This process requires personnel to operate the lifting equipment to make continuous adjustments, and the process is relatively complicated, which will affect the lifting efficiency. Therefore, there is an urgent need for a device that can improve the balance of the heliostat during the lifting process. Utility Model Content

[0005] In order to improve the balance of the heliostat during the hoisting process, the present application provides an energy-saving quick installation device for the heliostat of a tower-type solar thermal power station.

[0006] The present application provides an energy-saving quick installation device for heliostats in a tower-type solar thermal power station, which adopts the following technical solution:

[0007] An energy-saving quick installation device for a heliostat in a tower-type solar thermal power station comprises at least two hoisting assemblies and a positioning tube, and at least one of the hoisting assemblies and the positioning tube is provided at both ends of the heliostat hoisting tube;

[0008] The hoisting assembly comprises a hoisting frame and a hoisting belt, wherein one end of the hoisting belt is detachably connected to the hoisting frame;

[0009] The positioning tube is parallel to the hanging tube, one end of the positioning tube is connected to the hanging frame, and the other end is inserted into the hanging tube and detachably connected to the hanging tube, and the hanging frame is eccentrically connected to the positioning tube.

[0010] By adopting the above technical solution, in order to lift the heliostat, a lifting pipe is connected to the bottom of the heliostat. By inserting the positioning pipe into the lifting pipe, fixing the positioning pipe and the lifting pipe, and connecting the lifting equipment to one end of the lifting belt, the heliostat is lifted by the lifting frame and the positioning pipe. Since the heliostat may be in a tilted state on the transport vehicle, in order to ensure the balance of the heliostat during lifting, the lifting frame is eccentrically connected to the positioning pipe, that is, if the heliostat appears to be lower on one side and higher on the other side, the longer section of the installation position of the lifting frame and the heliostat from the end of the lifting frame is arranged on the same side as the higher side of the heliostat, and the shorter section of the installation position of the lifting frame and the heliostat from the end of the lifting frame is arranged on the same side as the lower side of the heliostat, so that the heliostat is quickly in a balanced state by the lifting frame. In addition, since the positioning pipe and the lifting pipe are detachably connected, when either of the positioning pipe and the lifting pipe is damaged, it can be replaced, thereby ensuring the maximum utilization of material energy.

[0011] Optionally, a first mounting hole is formed at both ends of the hanging tube, a second mounting hole is formed on one side of the positioning tube close to the end, the first mounting hole is connected to the second mounting hole, a first fixing member is provided in the first mounting hole, and the first fixing member passes through the first mounting hole and the second mounting hole in sequence.

[0012] By adopting the above technical solution, in order to fix the hanging tube and the positioning tube, a first mounting hole is provided on the hanging tube, and a second mounting hole is provided on the positioning tube. When the first mounting hole corresponds to the second mounting hole, the positioning tube and the hanging tube are fixedly connected by the first fixing member, thereby ensuring the stability of the heliostat and the positioning tube.

[0013] Optionally, the hanging frame includes a horizontally arranged fixing rod and a vertically arranged hanging rod, both ends of the fixing rod are fixedly connected to a hanging rod, one end of the hanging belt is directly or indirectly connected to the hanging rod, and the fixing rod is connected to the positioning tube.

[0014] By adopting the above technical solution, in order to facilitate the hoisting equipment to hoist the hoisting frame through the hoisting belt, the hoisting frame includes a fixing rod and a hoisting rod, so as to connect the hoisting belt with the hoisting rod, thereby improving the stability of the heliostat during the hoisting process.

[0015] Optionally, a positioning plate is fixedly connected to the end of the positioning tube, and a plurality of positioning members are fixedly connected to the side of the positioning plate away from the positioning tube. The fixing rod is provided with positioning holes corresponding to the positioning members along the length direction of the positioning tube, and one end of the positioning member is passed through the positioning hole and fixedly connected to the positioning hole.

[0016] By adopting the above technical solution, in order to better fix the positioning tube and the fixing rod, a positioning plate is provided at one end of the positioning tube, a plurality of positioning parts are provided on the positioning plate, and corresponding positioning holes are provided on the fixing rod. The positioning tube and the fixing rod are further connected through the matching relationship between the positioning parts and the positioning holes.

[0017] Optionally, one end of the positioning member passes through the positioning hole and penetrates in a vertical direction to form a limiting hole, and a second fixing member is threadedly connected in the limiting hole.

[0018] By adopting the above technical solution, the second fixing piece is threadedly connected to the limiting hole, thereby realizing a detachable connection between the positioning tube and the fixing rod. If the positioning tube is damaged, the detachable connection between the positioning tube and the fixing rod facilitates the installation and removal of the positioning tube and facilitates replacement.

[0019] Optionally, the plurality of positioning holes are located on the fixing rod near an end of the fixing rod.

[0020] By adopting the above technical solution, the positioning hole is located at the end of the fixing rod, which means that the positioning hole is located at a non-central position of the fixing rod, thereby achieving an eccentric connection between the positioning tube and the fixing rod.

[0021] Optionally, the outer diameter of the positioning tube is smaller than the inner diameter of the hanging tube, and one end of the positioning tube away from the positioning plate is coaxially fixedly connected with a first stabilizing plate, and the outer diameter of the first stabilizing plate is slightly smaller than the inner diameter of the hanging tube.

[0022] By adopting the above technical solution, in order to reduce the weight during lifting as much as possible, the outer diameter of the positioning tube is smaller than the inner diameter of the lifting tube. When the end of the positioning tube away from the positioning plate is located in the lifting tube, since the outer diameter of the positioning tube is smaller than the inner diameter of the lifting tube, in order to avoid the positioning tube from shaking in the lifting tube, a first stabilizing plate is provided at the end of the positioning tube away from the positioning plate, so that the first stabilizing plate can improve the stability of the positioning tube itself while ensuring the stability of the positioning tube in the lifting tube.

[0023] Optionally, a second stabilizing plate is coaxially sleeved on one side of the positioning tube close to the first stabilizing plate, the outer diameter of the second stabilizing plate is smaller than the outer diameter of the hanging tube, and the second mounting hole is located on the positioning tube between the first stabilizing plate and the second stabilizing plate.

[0024] By adopting the above technical solution, since the positioning tube has a certain length, in order to further improve the stability of the positioning tube, a second stabilization plate is fixedly mounted on one end of the positioning tube close to the first stabilization plate, and the stability of the positioning tube is improved by the first stabilization plate and the second stabilization plate.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The present application uses a hoisting frame eccentrically connected to the positioning tube. If the heliostat is tilted before hoisting, the hoisting frame is used to adjust the inclination of the heliostat during the hoisting process to ensure that the heliostat is in a balanced state;

[0027] 2. The present application uses a detachable connection between the positioning tube and the fixing rod, so when the positioning tube is damaged, it is convenient for personnel to replace it;

[0028] 3. This application further improves the stability of the positioning tube in the lifting tube and reduces the shaking of the positioning tube by setting a first stabilizing plate and a second stabilizing plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-7 This application is described in further detail.

[0038] Reference Figure 1A horizontally arranged hoisting pipe 02 is installed at the bottom of the heliostat 01, and the length of the hoisting pipe 02 is less than the length of the heliostat 01. The hoisting pipe 02 is arranged at the center of the bottom of the heliostat 01, and first installation holes 03 are opened through both ends of the hoisting pipe 02. During installation, the heliostat 01 is first transported to the construction site by a transport vehicle, and then the heliostat 01 is hoisted and installed by hoisting equipment.

[0039] The present application embodiment discloses an energy-saving quick installation device for heliostats in a tower-type solar thermal power station. Figure 1 and Figure 2 The quick installation device of the heliostat 01 of the tower-type solar thermal power station includes at least two lifting components 1 and a positioning tube 2. At least one lifting component 1 is provided at both ends of the heliostat 01. The lifting component 1 includes a lifting frame 11 and a lifting belt 12. One end of the lifting belt 12 is detachably connected to the lifting frame 11, and the other end is connected to a lifting device for lifting the lifting frame 11. The positioning tube 2 is arranged perpendicular to the lifting frame 11. One end of the positioning tube 2 is connected to the lifting frame 11, and the other end is inserted into the lifting tube 02 of the heliostat 01 and is detachably connected to the lifting tube 02. The lifting frame 11 is eccentrically connected to the positioning tube 2, so that the lifting tube 02 of the heliostat 01 is connected and fixed by the positioning tubes 2 provided at both ends of the heliostat 01. In this embodiment, two lifting components 1 and two positioning tubes 2 are provided.

[0040] Reference Figure 2 and Figure 3 In order to connect the positioning tube 2 and the hanging tube 02, a second mounting hole 21 is opened on one side of the positioning tube 2 near the end, the first mounting hole 03 is connected to the second mounting hole 21, and a first fixing member 22 is provided in the first mounting hole 03. The first fixing member 22 passes through the first mounting hole 03 and the second mounting hole 21 in sequence. In this embodiment, the first fixing member 22 can be a pin or a screw. The positioning tube 2 is slid along the inner wall of the hanging tube 02 to a state where the second mounting hole 21 is aligned with the first mounting hole 03, so as to fix the fixing tube and the hanging tube 02 through the first fixing member 22.

[0041] Reference Figure 2 The hanging frame 11 includes a horizontally arranged fixing rod 111 and a vertically arranged hanging rod 112. The fixing rod 111 is detachably connected to the positioning tube 2. Both ends of the fixing rod 111 are fixedly connected with a hanging rod 112. In order to be more firmly connected with the lifting belt 12, one end of the hanging rod 112 away from the fixing rod 111 is rotatably connected with a lifting ring 113. One end of the lifting belt 12 is wound around the lifting ring 113, so that the hanging frame 11 is hoisted to the installation position of the heliostat 01 by the hoisting equipment through the lifting belt 12.

[0042] Reference Figure 2 , Figure 3 and Figure 4In order to connect the fixing rod 111 and the positioning tube 2, a positioning plate 23 is coaxially fixedly connected to one end of the positioning tube 2, and a plurality of positioning members 231 are fixedly connected to the end of the positioning plate 23 away from the positioning tube 2, and the distance between each two adjacent positioning members 231 is equal. A positioning hole 1111 corresponding to the positioning member 231 is penetrated and opened near the end of the fixing rod 111. In some embodiments, one or more positioning holes 1111 may be provided. In this embodiment, three positioning holes 1111 are provided. Before lifting, the heliostat 01 is transported by a transport vehicle, and the heliostat 01 may be in a tilted state on the transport vehicle. When the heliostat 01 is lifted to a certain position by a lifting device, When determining the height, in order to ensure that the heliostat 01 is in a horizontal state, the three positioning holes 1111 are located at a non-central position of the fixing rod 111. When the heliostat 01 is in a state where one side is higher than the other side, the positioning holes 1111 on the fixing rod 111 are located at a longer section away from the end of the hanging frame 11 and are arranged on the same side as the higher side of the heliostat 01, and the positioning holes 1111 on the fixing rod 111 are located at a shorter section away from the end of the hanging frame 11 and are arranged on the same side as the lower side of the heliostat 01. The longer section of the positioning holes 1111 on the fixing rod 111 is heavier, so as to apply downward gravity to the heliostat 01 on the higher side, thereby quickly bringing the heliostat 01 into a balanced state.

[0043] Reference Figure 4 In some embodiments, the positioning member 231 can be welded into the positioning hole 1111 to achieve a fixed connection between the positioning tube 2 and the fixing rod 111 .

[0044] Reference Figure 5 In order to facilitate installation and disassembly, in other embodiments, the positioning member 231 is detachably connected to the positioning tube 2. Specifically, one end of the positioning member 231 is inserted into the corresponding positioning hole 1111, and one end of the positioning member 231 that passes through the positioning hole 1111 is provided with a limiting hole 2311 in the vertical direction. The limiting hole 2311 is threadedly connected with a second fixing member 2312. In this embodiment, the second fixing member 2312 can be a pin or a screw, and the positioning tube 2 and the fixing rod 111 are fixedly connected by the second fixing member 2312. When the positioning tube 2 is damaged, it is convenient for personnel to disassemble and replace the positioning tube 2 and the fixing rod 111.

[0045] Reference Figure 2 and Figure 6During the lifting process, in order to reduce the weight as much as possible, the outer diameter of the positioning tube 2 is smaller than the inner diameter of the lifting tube 02. When in use, the end of the positioning tube 2 away from the positioning plate 23 is inserted into the lifting tube 02. Since the outer diameter of the positioning tube 2 is smaller than the inner diameter of the lifting tube 02, in order to improve the stability of the positioning tube 2 in the lifting tube 02, the end of the positioning tube 2 away from the positioning plate 23 is coaxially fixedly connected with the first stabilizing plate 24. In this embodiment, the first stabilizing plate 24 is a circular plate, and the outer diameter of the first stabilizing plate 24 is slightly smaller than the outer diameter of the lifting tube 02 to reduce the shaking of the positioning tube 2 in the lifting tube 02.

[0046] Reference Figure 2 and Figure 6 When the first stabilizing plate 24 is located in the hanging tube 02, since the positioning tube 2 has a certain length, and the positioning plate 23 located at one end of the positioning tube 2 is connected with the fixing rod 111 and the hanging rod 112, in order to further improve the stability and balance of the positioning tube 2, the end of the positioning tube 2 close to the first stabilizing plate 24 is coaxially sleeved with the second stabilizing plate 25, and the outer diameter of the second stabilizing plate 25 is smaller than the outer diameter of the first stabilizing plate 24. The second mounting hole 21 is located on the positioning tube 2 between the first stabilizing plate 24 and the second stabilizing plate 25. When in use, the end of the positioning tube 2 away from the positioning plate 23 is inserted into the hanging tube 02. At this time, the first stabilizing plate 24 and the second stabilizing plate 25 are both located in the hanging tube 02. The first stabilizing plate 24 and the second stabilizing plate 25 ensure the balance of the positioning tube 2 in the hanging tube 02, thereby further ensuring the stability of the heliostat 01 during the hanging process.

[0047] Reference Figure 7 When hoisting with the hoisting equipment, in order to facilitate the personnel on the ground to further control the direction and angle of the heliostat 01, the tower-type solar thermal power station heliostat rapid installation device also includes a plurality of traction ropes 3, one end of which is fixedly connected to one end of a hoisting rod 112, and another end of which is fixedly connected to one end of another hoisting rod 112. The personnel manually adjust the angle of the heliostat 01 by pulling the traction rope 3.

[0048] The implementation principle of an energy-saving quick installation device for a heliostat in a tower-type solar thermal power station according to an embodiment of the present application is as follows: before installation, the heliostat 01 is first transported to the construction site by a transport vehicle, and personnel fix the positioning tube 2 and the fixing rod 111 with a locking nut, and insert the positioning tubes 2 on both sides of the heliostat 01 into the two ends of the lifting tube 02 respectively. When the first positioning hole 1111 is aligned with the second positioning hole 1111, the first fixing member 22 is inserted into the first positioning hole 1111 and the second positioning hole 1111 in sequence to fix the fixing rod 111 and the positioning tube 2, thereby fixing the positioning tube 2 and the heliostat 01. Then, the lifting belt 12 is lifted up on the side away from the lifting ring by the lifting equipment, and the heliostat 01 is further lifted by the fixing rod 111 and the positioning tube 2.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
