Description

Technical Field

[0001] The utility model relates to the technical field of solar power generation, and particularly relates to a heliostat installation device. Background Art

[0002] A heliostat (also known as a "sidereostat") is an optical device that reflects the light of the sun or other celestial bodies to a fixed direction. A heliostat is a core component of a tower-type solar thermal power plant. Through computer control, the angle of the heliostat is adjusted in real time according to the position of the sun. The tower-type solar thermal power generation technology uses the heliostat to track the sun so that its reflected light can be accurately projected onto the heat absorber heat transfer surface placed at the top of the receiving tower. The heat absorber converts solar energy into heat energy and heats the medium (water or other fluid) flowing in the coil to generate high-temperature steam to drive a steam turbine generator set to generate electricity.

[0003] When building a heliostat field, first, columns need to be fixedly installed at the set positions, a connecting seat is installed at the upper end of the installed column, the heliostat is installed on the connecting seat, and the connecting seat can drive the heliostat to move following the sun.

[0004] In each heliostat field, many heliostats usually need to be set. Currently, when installing a heliostat, usually a rope is tied to the heliostat, and then the heliostat is hoisted to the installation position by a hoisting tool such as a crane. Workers support the heliostat to swing and adjust the position, and then install the heliostat on the mounting seat. During the whole hoisting process, on the one hand, the lifting rope directly contacts the heliostat, and the whole heliostat is exposed outside, which is easy to damage the heliostat. On the other hand, for a heliostat with a large area, hoisting with a rope has certain risks and is inconvenient for actual use. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a heliostat installation device, which can stably hoist the heliostat to the installation position by a hoisting device, and use a hoisting frame to support the heliostat, so that the heliostat is evenly stressed and damage is avoided.

[0006] For the above technical problem, the technical solution provided by the utility model is a heliostat installation device, including two support vertical beams arranged at intervals in the transverse direction. The upper ends of the two support vertical beams are connected with a support cross beam, and the lower ends are provided with a moving mechanism. A hoisting device is arranged on the support cross beam. The hoisting device includes a transverse hoisting mechanism, a longitudinal hoisting mechanism and a vertical lifting mechanism. The transverse hoisting mechanism is used to drive the longitudinal hoisting mechanism to move in the transverse direction. The longitudinal hoisting mechanism is used to drive the vertical lifting mechanism to move in the longitudinal direction. The lower part of the vertical lifting mechanism is connected with a hoisting frame through a connecting piece. The hoisting frame is used to place the heliostat, and the vertical lifting mechanism is used to drive the hoisting frame to move in the vertical direction.

[0007] Further, the inner cavity of the hoisting frame is an installation cavity adapted to the size of the heliostat, and a supporting structure is arranged in the installation cavity for supporting the heliostat.

[0008] Further, the supporting structure includes two longitudinal supporting rods arranged at intervals in the transverse direction in the installation cavity, and the longitudinal supporting rods are detachably connected to the hoisting frame.

[0009] Further, the hoisting frame includes two transverse frames and two longitudinal frames. Installation through holes are arranged at positions corresponding to the longitudinal supporting rods on the transverse frames of the hoisting frame. Both ends of the longitudinal supporting rods respectively pass through the corresponding installation through holes and extend out of the hoisting frame. Fasteners are arranged at the ends of the longitudinal supporting rods extending out of the hoisting frame for fastening the longitudinal supporting rods on the hoisting frame.

[0010] Further, a plurality of installation through holes are arranged at intervals in the transverse direction on the transverse frame.

[0011] Further, the upper side surface of the part of the longitudinal supporting rod in the installation cavity is a plane.

[0012] Further, the transverse hoisting mechanism includes a transverse mounting seat fixedly installed at the lower end of the support cross beam. A transverse lead screw is rotatably installed on the transverse mounting seat. A transverse sliding block is threadedly connected to the transverse lead screw. The transverse sliding block is arranged to slide transversely on the transverse mounting seat. The longitudinal hoisting mechanism includes a longitudinal mounting seat fixedly installed on the transverse sliding block. A longitudinal lead screw is rotatably installed on the longitudinal mounting seat. A longitudinal sliding block is threadedly connected to the longitudinal lead screw. The longitudinal sliding block is arranged to slide longitudinally on the longitudinal mounting seat.

[0013] Further, transverse sliding grooves are symmetrically arranged on the longitudinal side surfaces of the support cross beam. Sliding members are slidably arranged in the transverse sliding grooves. Connecting rods are connected between the longitudinal two sides of the longitudinal mounting seat and the corresponding sliding members.

[0014] Further, a hanging plate is connected to the lower end of the vertical lifting mechanism. The connecting member includes a plurality of suspension cables connected between the hanging plate and the hoisting frame.

[0015] Further, the moving mechanism includes traveling wheels arranged at the bottom of the support vertical beam.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] (1) The support cross beam and the two support vertical beams can form a gantry structure. The mobile mechanism can drive the gantry structure to move. When installing the heliostat, it is convenient for transportation and placement of the heliostat, and there is no need to set up mechanisms such as cranes. The operation is simple. The lifting frame can carry and place the heliostat, avoiding direct contact between the heliostat and the lifting rope, ensuring uniform force on the heliostat. At the same time, it can prevent the surroundings of the heliostat from being exposed, reducing the possibility of collision between the heliostat and the outside world during lifting and decreasing the probability of damage to the heliostat. Meanwhile, the lifting frame can prevent the heliostat from falling off, improving safety. The lifting mechanism can drive the heliostat to move horizontally, longitudinally and vertically. On the one hand, it is convenient to adjust the installation position of the heliostat, improving the installation accuracy. On the other hand, it can reduce the sway of the heliostat during movement, improving the operation safety.

[0018] (2) The placement cavity can be used to place the heliostat inside the lifting frame and prevent the heliostat from shaking and being damaged. The longitudinal support rod can, on the one hand, facilitate the support of the heliostat, and on the other hand, avoid blocking the part where the lower part of the heliostat is connected to the installation column, preventing installation interference. The longitudinal support rod is detachably connected to the lifting frame. After the heliostat is lifted to the designated position, the lifting frame and the heliostat can be separated by removing the longitudinal support rod, and the operation is convenient.

[0019] (3) The upper side of the longitudinal support rod is a plane. This plane is used to facilitate the support of the heliostat, increase the contact area with the heliostat, reduce the pressure, and avoid damage to the heliostat.

[0020] (4) Through the cooperation of the connecting rod, the sliding part and the transverse chute, on the one hand, it guides the movement of the longitudinal lifting mechanism on the transverse lifting mechanism to ensure stable movement. On the other hand, when the heliostat moves longitudinally on the longitudinal lifting mechanism, the connecting rods on both sides can provide support force and tensile force to ensure the stability of the longitudinal mounting seat and improve safety.

Detailed implementation manners

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application: Specific Embodiment 1:

[0031] In this embodiment, as Figure 1 shown, the horizontal direction is the length direction of the support cross beam 2, and the vertical direction is the width direction of the support cross beam 2.

[0032] Referring to Figures 1 to 5 , a heliostat installation device of the present utility model includes two support vertical beams 1 arranged at intervals in the horizontal direction. The upper ends of the two support vertical beams 1 are connected with a support cross beam 2, and a moving mechanism 3 is arranged at the lower ends of the two support vertical beams 1. The moving mechanism 3 drives the heliostat installation device to move.

[0033] In this embodiment, a lifting device is arranged on the support cross beam 2. The lifting device includes a horizontal lifting mechanism 41, a vertical lifting mechanism 42 and a vertical lifting mechanism 43. Among them, the horizontal lifting mechanism 41 is used to drive the vertical lifting mechanism 42 to move horizontally, the vertical lifting mechanism 42 is used to drive the vertical lifting mechanism 43 to move vertically, and the lower part of the vertical lifting mechanism 43 is connected with a lifting frame 5 through a connecting piece. The lifting frame 5 is used to place the heliostat, and the vertical lifting mechanism 43 is used to drive the lifting frame 5 to move vertically. In this way, the heliostat can be supported by the lifting frame 5, and the heliostat can be driven to move in three-dimensional space through the lifting device, so as to facilitate adjusting the installation position of the heliostat and facilitating the installation of the heliostat on the connecting seat of the installation column.

[0034] Specifically, in this embodiment, as Figure 1 ,2 As shown in the figure, the lifting frame 5 is a cuboid frame structure surrounded by two transverse frames 52 and two longitudinal frames 53. The interior of the lifting frame 5 is hollow, and its inner cavity is an installation cavity 51 adapted to the size of the heliostat. And a supporting structure is also arranged in the installation cavity 51, and the supporting structure is used to support the heliostat. In this way, the heliostat can be placed inside the lifting frame 5 by using the installation cavity 51, and the shaking and damage of the heliostat can be avoided. The supporting structure is used to prevent the heliostat from falling off.

[0035] Preferably, in this embodiment, the supporting structure includes two longitudinal supporting rods 6 arranged at intervals in the transverse direction in the installation cavity 51. The two longitudinal supporting rods 6 are respectively arranged near the two transverse sides of the installation cavity 51, and the longitudinal supporting rods 6 are detachably connected to the lifting frame 5. With such a setting, on the one hand, the longitudinal supporting rods 6 are convenient for supporting the heliostat, and on the other hand, the area between the two longitudinal supporting rods 6 is a blank area, which can avoid blocking the part of the heliostat connected to the connecting seat below and avoid installation interference of the heliostat. At the same time, the longitudinal supporting rods 6 are detachably connected to the lifting frame 5. After the heliostat is lifted to the designated position and fixed on the connecting seat, the lifting frame 5 can be separated from the heliostat by removing the longitudinal supporting rods 6, and the operation is convenient.

[0036] Specifically, in this embodiment, installation through holes 54 are opened at the positions corresponding to the two ends of the longitudinal supporting rods 6 on the two transverse frames 52 of the lifting frame 5. The two ends of the longitudinal supporting rods 6 respectively pass through the corresponding installation through holes 54 and extend out of the lifting frame 5. Fasteners 7 are arranged at the ends of the longitudinal supporting rods 6 extending out of the lifting frame 5, and the fasteners 7 are used to fasten the longitudinal supporting rods 6 on the lifting frame 5. Specifically, in this embodiment, the fasteners 7 are limit sleeves. After the longitudinal supporting rods 6 are inserted into the lifting frame 5, the movement of the longitudinal supporting rods 6 can be restricted by sleeving limit sleeves at the ends of the longitudinal supporting rods 6. Of course, in other embodiments, threaded sections can be arranged at the two ends of the longitudinal supporting rods 6, and at this time, the fasteners 7 are fastening nuts.

[0037] Preferably, in this embodiment, as Figure 4 、 5 shown, the upper side of the part of the longitudinal supporting rod 6 in the installation cavity 51 is a plane. This plane constitutes a supporting surface 61 for supporting the heliostat. Specifically, in this embodiment, the longitudinal supporting rod 6 is integrally in a columnar structure. At a position in the middle that is adapted to the longitudinal dimension of the installation cavity 51, a groove notch is radially opened along the longitudinal supporting rod 6, and the bottom surface of the groove notch is the supporting surface 61. With such a setting, on the one hand, the supporting surface 61 is convenient for supporting the heliostat, and the contact area with the heliostat is increased, the pressure is reduced, and damage to the heliostat is avoided. On the other hand, after the heliostat is placed on the supporting surface 61, the rotation of the longitudinal supporting rod 6 can be restricted, and the stability is improved. Of course, in other embodiments, when the weight of the heliostat is small, the supporting surface 61 may not be provided, and at this time, the longitudinal supporting rod 6 is a cylindrical smooth rod structure.

[0038] In this embodiment, preferably, a rubber gasket (not shown in the figure) is adhered to the surface of the longitudinal support rod 6, and the rubber gasket is used for buffering to protect the heliostat. Specifically, the rubber gasket is adhered to the support surface 61.

[0039] In this embodiment, preferably, as Figure 2 shown, a plurality of mounting through holes 54 are arranged at intervals in the transverse direction on the transverse frame 52 of the lifting frame 5, and the mounting through holes 54 on the two transverse frames 52 are symmetrically arranged. Such a setting can, on the one hand, increase the number of longitudinal support rods 6 according to factors such as the size, shape, and weight of the heliostat during actual lifting, improving practicability and safety. On the other hand, by inserting the longitudinal support rod 6 into different mounting through holes 54, the position of the longitudinal support rod 6 can be adjusted, and thus the heliostat of different sizes can be adapted to be lifted, or the support position of the longitudinal support rod 6 for supporting the heliostat can be adjusted, providing versatility.

[0040] In this embodiment, as Figure 1 shown, the transverse lifting mechanism 41 includes a transverse mounting seat 411 fixedly installed at the lower end of the support cross beam 2, and a transverse lead screw 412 is rotatably installed on the transverse mounting seat 411. Specifically, a transverse mounting groove is formed at the lower end of the transverse mounting seat 411, and both ends of the transverse lead screw 412 are respectively rotatably installed on the two transverse side walls of the transverse mounting groove. A transverse driving motor 414 is arranged outside one transverse end of the transverse mounting seat 411, and the transverse driving motor 414 is in anti-rotation cooperation with this end of the transverse lead screw 412, and the transverse driving motor 414 drives the transverse lead screw 412 to rotate.

[0041] A transverse sliding block 413 is threadedly connected to the transverse lead screw 412. The transverse sliding block 413 is adapted to the transverse mounting groove, and the upper end of the transverse sliding block 413 is attached to the upper groove wall of the transverse mounting groove. The rotation of the transverse sliding block 413 is restricted by the transverse mounting groove, and thus the transverse lead screw 412 and the transverse sliding block 413 form a transverse lead screw-nut mechanism. Driving the transverse driving motor 414 can drive the transverse sliding block 413 to translate in the transverse direction.

[0042] In this embodiment, a card interface that penetrates longitudinally is provided at the lower end of the transverse sliding block 413. The longitudinal lifting mechanism 42 includes a longitudinal mounting seat 421. The width dimension of the longitudinal mounting seat 421 is adapted to the card interface, and the longitudinal mounting seat 421 is clamped in the card interface and fixed on the transverse sliding block 413.

[0043] A longitudinal lead screw 422 is rotatably mounted on the longitudinal mounting base 421. Specifically, as described above, a longitudinal mounting groove is formed at the lower end of the longitudinal mounting base 421, and both ends of the longitudinal lead screw 422 are rotatably mounted on the two longitudinal side walls of the longitudinal mounting groove. A longitudinal driving motor 424 is disposed outside the lateral end of the longitudinal mounting base 421. The longitudinal driving motor 424 is in non-rotating fit with this end of the longitudinal lead screw 422, and the longitudinal lead screw 422 is driven to rotate by the longitudinal driving motor 424.

[0044] A longitudinal sliding block 423 is threadedly connected to the longitudinal lead screw 422. The longitudinal sliding block 423 is adapted to the longitudinal mounting groove. The upper end of the longitudinal sliding block 423 is attached to the upper groove wall of the longitudinal mounting groove. The rotation of the longitudinal sliding block 423 is restricted by the longitudinal mounting groove, so that the longitudinal lead screw 422 and the longitudinal sliding block 423 form a longitudinal lead screw-nut mechanism. Driving the longitudinal driving motor 424 can drive the longitudinal sliding block 423 to translate longitudinally.

[0045] In this embodiment, the vertical lifting mechanism 43 includes a vertical cylinder. The upper end of the vertical cylinder is connected to the lower end of the longitudinal sliding block 423, and the lower end of the vertical cylinder is connected to a suspension plate 8. The connecting member includes a plurality of suspension cables 9 connected between the suspension plate 8 and the hoisting frame 5. Specifically, the suspension plate 8 is a rectangular plate. Hoisting rings (not shown in the figure) are provided at the middle positions around the suspension plate 8 and the hoisting frame 5. One suspension cable 9 is connected to the corresponding two hoisting rings. The heliostat is hoisted by four suspension cables 9 to ensure stable hoisting. Of course, in other embodiments, the number of the suspension cables 9 can be set according to actual requirements, such as 6, 8, etc., and is not limited herein.

[0046] Of course, in other embodiments, when meeting the actual use requirements, the vertical lifting mechanism 43 can also be a structure such as a driving oil cylinder, as long as it can meet the lifting requirements, and is not limited herein.

[0047] In this embodiment, as Figure 1 shown, the moving mechanism 3 includes a moving base 31 fixedly mounted at the lower end of the support vertical beam 1. A longitudinally extending opening groove is formed at the lower end of the moving base 31. A traveling wheel 32 is rotatably mounted at each of the two longitudinal ends of the opening groove. The entire heliostat mounting device is supported by four traveling wheels 32 to ensure stability. In this embodiment, a self-locking brake pedal is further provided on the traveling wheel 32.

[0048] Preferably, in this embodiment, the traveling wheel 32 is a universal wheel to improve flexibility.

[0049] Working process of this application: First, pre-install the heliostat in the lifting frame 5, then adjust the horizontal position through the horizontal lifting mechanism 41, adjust the vertical position through the vertical lifting mechanism 42, and adjust the installation height through the vertical lifting mechanism 43. When reaching the specified installation position, connect and fix the heliostat to the connecting seat on the installation column. After the connection is completed, remove the longitudinal support rod 6, and the heliostat can be separated from the lifting frame 5 to complete the installation. It has high efficiency and can reduce damage to the heliostat, with strong practicability.

[0050] In summary, the heliostat installation equipment of the present utility model utilizes the support cross beam 2 and the two support vertical beams 1 to form a gantry structure, and the moving mechanism 3 can drive the gantry structure to move. When installing the heliostat, it is convenient for transportation and the heliostat, and there is no need to set up mechanisms such as cranes, with simple operation. The lifting frame 5 can be used to carry and place the heliostat, avoiding direct contact between the heliostat and the lifting rope, with uniform force on the heliostat. At the same time, it can prevent the four sides of the heliostat from being exposed, reducing the possibility of collision between the heliostat and the outside during lifting and decreasing the probability of damage to the heliostat. At the same time, the lifting frame 5 can be used to prevent the heliostat from falling off, improving safety; the lifting mechanism can drive the heliostat to move horizontally, longitudinally and vertically. On the one hand, it is convenient to adjust the installation position of the heliostat, improving the installation accuracy. On the other hand, it can reduce the shaking of the heliostat during movement, improving the operation safety.

Connecting rods 12 are connected between the longitudinal two sides of the longitudinal mounting seat 421 and the corresponding sliding members 11. In this way, through the cooperation of the connecting rods 12, the sliding members 11 and the horizontal sliding grooves 10, on the one hand, it can guide the horizontal movement of the longitudinal lifting mechanism 42 on the horizontal lifting mechanism 41 to ensure stable movement. On the other hand, when the heliostat moves longitudinally on the longitudinal lifting mechanism 42, the two side connecting rods 12 can be used to provide support force and pulling force to ensure stable lifting and improve safety.

[0052] Preferably, in this embodiment, as Figure 7 shown, the horizontal sliding groove 10 can be a T-shaped groove with an opening facing outwards, and the sliding member 11 is a T-shaped slider adapted to the T-shaped groove. In this way, the T-shaped groove and the T-shaped sliding groove can be used to prevent the T-shaped slider from falling off and make the overall force of the longitudinal lifting mechanism 42 stable.
