Description

Technical Field

[0001] This application relates to the technical field of tower solar thermal power generation, and particularly to an integrated heliostat single-mirror control system. Background Art

[0002] Tower solar thermal power generation (CSP: Concentrating Solar Power) is an energy conversion technology for effectively utilizing solar energy for power generation. The solar heat collection system consists of a concentrating heliostat field and a receiver located on the central tower. The light spots of each heliostat in the heliostat field are concentrated on the receiver located on the high tower at the center of the field for focusing, and the working fluid circulation is heated. The heated working fluid is stored in a high-temperature molten salt storage tank, and then the hot working fluid is driven by a hot salt pump to exchange heat with water and steam through a heat exchanger. Thus, superheated steam and reheated steam are generated to drive a steam turbine to drive a generator for power generation.

[0003] Since the number of CSP heliostats is huge and the heliostats are arranged in an outdoor environment, when designing, it is necessary to consider the layout of the heliostat control box, the protection of the control box, the functions of the heliostat controller, as well as the form and functions integrated in the heliostat control box. At the same time, factors such as the overhaul and maintenance of the heliostat control system and cost control also need to be considered.

[0004] The heliostat control system is the core equipment of the heliostat. It communicates with the upper system upward and controls the operation of the heliostat downward and other main functions. The rationality of its equipment layout, layout, and functions directly affects the stability and reliability of the entire heliostat field control system. At the same time, the design from aspects such as cost control, on-site maintenance, and layout aesthetics is of great significance to the whole field.

[0005] Currently, the equipment layout in the control box adopts a traditional method, where the controller and the motor driver are set separately. The integration degree of the heliostat control system is relatively low, and the heat dissipation performance is poor.

[0006] Therefore, how to improve the integration degree and heat dissipation performance of the heliostat single-mirror control system has become an urgent technical problem to be solved. Utility Model Content

[0012] Heat dissipation fins, arranged on the back of the control box, are used to dissipate heat for the controller and the power supply module.

[0013] A hand-operated device aviation plug, installed at the bottom of the control box, is used to connect with the interface of a portable hand-operated device.

[0014] Preferably, a box door, which is hinged to the control box. The box door and / or the control box are provided with grooves, and the grooves are fitted with seals.

[0015] Preferably, a circuit breaker, arranged on the inner wall of the control box, is used to disconnect the incoming power supply.

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments of this specification, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0030] As Figure 1 shown Figure 1 Schematic diagram of the deployment layout of an integrated heliostat single-mirror control system.

[0031] The present utility model provides an integrated heliostat single-mirror control system, including: control box 1, controller 5, heat dissipation fin 4, handheld operator aviation plug 17, circuit breaker 7, emergency stop device 16, fixing bracket 12, grounding copper bar 14, power supply module 6, braking resistor 11, etc.

[0032] The control box 1 is made of die-cast aluminum, formed by die-casting of a mold, with good shape consistency and short production cycle; the controller 5 is mounted on the inner wall of the control box, and includes a control module and a drive module.

The emergency stop device can be a button, which realizes the rapid shutdown protection for emergencies during on-site debugging and maintenance trial operation, enabling emergency operation without opening the box, improving the convenience and safety of on-site debugging and maintenance, and thus significantly shortening the time required for heliostat debugging.

[0039] The fixing bracket 12 is fixed to the inner wall of the control box 1 by M4 bolts 10, and there are multiple of them, which realizes the wiring of electrical equipment and the fixing of incoming and outgoing cables in the control box 1. The fixing bracket can make the wiring in the box beautiful and tidy.

[0040] The grounding copper bar 14 is fixed to the inner wall of the control box 1 by M5 bolts 13, which meets the requirements of protective grounding and working grounding for electrical equipment in the box. The grounding copper bar can meet the grounding function of electrical equipment.

[0041] The control box is provided with a hole structure for incoming and outgoing lines. A sealing joint is installed on the hole structure for fixing the incoming and outgoing cables and sealing the control box.
