Description

Technical Field

[0001] The present application relates to the technical field of tower solar thermal power generation, and in particular to a novel integrated wiring heliostat system. Background Art

[0002] Tower solar thermal power generation (CSP: Concentrating Solar Power) is an energy conversion technology that effectively utilizes solar energy for power generation. The solar thermal collection system consists of a concentrating heliostat field and a heat absorber located on the central tower. The light spot of each heliostat in the heliostat field is focused on the heat absorber located on the high tower in the center of the field, and the working fluid is circulated and heated. The heated working fluid is stored in a high-temperature storage tank, and then the hot working fluid is driven by a heat pump to exchange heat with water and steam through a heat exchanger, thereby generating superheated steam to drive the steam turbine to drive the generator to generate electricity. CSP heliostats are huge in number, and the design needs to consider many factors such as the integrated wiring of heliostats, the installation of control boxes, the installation and maintenance of detection components and transmission components, as well as the cost control during the construction and operation periods.

[0003] The control box, motor and sensor are the core equipment of the heliostat system. The controller in the control box has local and remote operation functions, automatic tracking of the sun's trajectory algorithm function, as well as communication with the host computer and monitoring the heliostat downward. The rationality of the heliostat equipment layout, installation and wiring directly affects the performance, cost, maintenance and aesthetics of the entire heliostat, and is of great significance to the overall design.

[0004] However, most of the existing tower heliostat piles on the market use prestressed high-strength concrete piles, referred to as "PHC piles". If the upper down-lead wire of the heliostat is wired in the PHC pile, it is necessary to reserve inlet and outlet holes at the upper and lower parts of the pile, and the size of the holes needs to meet the wiring space. If the pile is installed by pile pressing, there will be local stress deformation and cracking at the reserved holes during the pile pressing process, which will increase the probability of pile explosion during the installation process, thereby affecting the installation progress of the heliostat system and increasing the cost; secondly, if the wiring harness of the upper part of the heliostat in the heliostat system is laid openly, the wiring harness fixing scheme is mostly clamped, and the control box is also fixed with a clamp. During the installation process, it requires the cooperation of multiple personnel to complete. At the same time, it also affects the replacement and maintenance of the wiring harness, and the overall layout effect is not very perfect. Utility Model Content

[0005] In order to solve or partially solve the problems existing in the related art, the present application provides a new integrated wiring heliostat system, which facilitates the replacement and maintenance of the wiring harness by the staff without reserving wiring holes, thereby improving the overall layout effect.

[0011] The π-shaped wire buckle is used to fix the wire harness with a connector which is exposed on the heliostat support pipe pile; the wire harness is at least used to connect the controller in the control box and the drive assembly.

[0012] In some embodiments, a control box hanger is installed on the back of the control box, and an octagonal bracket is installed at a preset position of the heliostat supporting pipe pile; wherein the M8 bolt of the octagonal bracket is compatible with the M8 threaded sleeve set at the preset position, and the control box hanger is hung on the octagonal bracket.

[0013] In some embodiments, the π-shaped wire buckle is used to mount the wire harness buckle on the heliostat support pipe pile, and the π-shaped wire buckle is fixed by an M6 bolt and an M6 threaded sleeve.

[0017] In some embodiments, the wiring harness fixing bracket provided on the driving assembly is used to fix the wiring harness of the pitch motor and the pitch axis limit sensor.
