[0030] Optionally, the tension transmitter is connected to the CPU module via an RS485 network structure.
[0031] This technical solution aims at the problem that after the construction of a photovoltaic power station using a flexible bracket is completed, as time goes by, the steel cable is easily loosened due to long-term large tension, which in turn affects the safe operation of the photovoltaic power station. The utility model installs a tension sensor on the steel cable of the flexible bracket, which can monitor the tension of the steel cable of the flexible bracket in real time. An electric push rod is installed at the terminal of the steel cable. When the steel cable is loose, the push rod can be used to tension the steel cable to adjust the tension of the steel cable, which provides a good tool for the later operation and maintenance of the photovoltaic power station.
[0032] The above technical solution is described in detail with reference to the accompanying drawings:
[0033] Photovoltaic flexible support structure Figure 1 As shown, the flexible bracket is a method of replacing the purlins of the traditional rigid bracket solution with steel strands. Its characteristics are that the steel strands provide pre-tensioning force, and the steel strands are allowed to have a certain deformation under different working conditions after the components are installed, thereby realizing a large-span bracket that can meet the needs of different terrains. A group of beams is provided in the photovoltaic flexible bracket, and the beams are vertically arranged on the columns for fixing the beams. The columns are fixed on the ground to support and fix the beams. Several steel cables are arranged between the beams, and the steel cables include component cables and load-bearing cables. The tension sensor is installed on the steel cable of the photovoltaic flexible bracket to detect the tension value of the steel cable in real time. Each group of flexible brackets includes 2 component cables and 1 load-bearing cable, and the tension transmitter, power module, CPU module, communication module, and push rod driver are installed in the control box.
[0034] As above Figure 2 As shown, the power module provides power to the sensor, transmitter, push rod driver, CPU module, and 4G Internet of Things communication module respectively.
[0035] As above Figure 3As shown in the figure, the side pressure tension sensor converts the tension value of the steel cable into a weak voltage signal, which is connected and connected to the tension transmitter through a cable. Each tension transmitter can connect up to 16 tension sensors. The tension transmitter converts the voltage signal of the sensor into a standard RS485 network level signal. The CPU module collects each channel of data from each tension transmitter through the RS485 network structure, thereby obtaining the current tension value of the corresponding steel cable to realize the tension monitoring function. At the same time, the CPU module sends the tension value of each steel cable to the communication module of the 4G Internet of Things, and the communication module of the 4G Internet of Things uploads the data to the mobile terminal or cloud database through the 4G network for storage.
[0036] The CPU module is connected to the driver and the electric push rod in sequence. The relevant personnel input the relevant signal through the external key connected to the CPU module to drive the electric push rod to tension the steel cable through the driver. The electric push rod is also called a linear drive. It is mainly a new type of linear actuator composed of a motor push rod and a control device. This mechanism is well known to people in this field and will not be described here.
[0037] The CPU module continuously reads the tension value of all current steel cables. Relevant personnel can check that when the tension value of the current steel cable is lower than the standard value, it means that the steel cable may be loose. At the same time, the system sends relevant information to the operation and maintenance personnel through the 4G Internet of Things communication module. At the same time, in order to facilitate the use of the communication module and the CPU module, an alarm module is also connected. The alarm module uses a buzzer or an audible and visual alarm device to alarm the tension value. At the same time, the CPU module is connected to an external button to control the operation of the driver.
[0038] After the construction of the photovoltaic power station is completed, the steel cable will be subjected to high-intensity stress for a long time, which may cause the cable structure to loosen slowly. This slow loosening is difficult for the operation and maintenance personnel to detect. This system can detect the tension of the steel cable in real time, and allow relevant personnel to tighten the steel cable through the controller. Once an abnormality occurs, an immediate alarm will be issued to remind the operation and maintenance personnel to check, thereby avoiding the occurrence of operation and maintenance accidents and economic losses.
[0039] In addition to using lateral pressure tension sensors, anchor dynamometers or other structural sensors can also be used to detect the tension of the steel cable. In addition to using electric push rods, various drive motors can also be used as power to tension the steel cable. Use tension sensors to detect the tension of the steel cable of the flexible bracket in real time. Use 4G Internet of Things communication modules to upload data to mobile terminals or cloud database storage in real time. Use electric push rods to tension the steel cable.
[0040] The electronic devices used in the present invention, including various sensors, processors, various modules, electric push rods, etc., are all standard devices or devices available on the market. Each of these devices is equipped with conventional existing programs, or has its own physical structure necessary to realize the functions of this system. The connections between all these devices, including the configuration of interfaces and wires, adopt standard connection methods that are widely recognized and implemented in the industry. These technical details are well known to technicians in this field, so they will not be described in detail here. At the same time, it should be noted that the present invention mainly protects the overall structure formed after the connection.
[0041] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
