[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The purpose of this invention is to provide a low-heat-generating wedge-shaped tension clamp crimping structure, which can effectively solve the problems of tension clamp and transmission line slippage and tension clamp overheating during the operation of the power transmission network, and even reduce the corrosion problem of the tension clamp.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Figure 1 -3 is a residential photovoltaic panel bracket provided in an embodiment of the present invention, including a base bracket 1, an inclined support block 2, a photovoltaic panel connecting plate 3, a height adjustment mechanism 4, an angle adjustment mechanism 5, an angle measurement module, and a central control system.

[0033] Among them, the base bracket 1 is a structure consisting of multiple supporting base platforms, which is the installation foundation for the household photovoltaic panel bracket.

[0034] The inclined support block 2 is inclinedly installed on one side of the base platform of the base bracket 1. The inclined surface of the installation angle adjustment mechanism 5 of the inclined support block 2 faces the sun and the inclined surface faces the height adjustment mechanism 4.

[0035] The photovoltaic panel connecting plate 3 has a rectangular frame structure, which reduces costs and supports the photovoltaic panels. The photovoltaic panel connecting plate 3 can be composed of four perforated channel steels with multiple hole specifications to accommodate the fastening installation of photovoltaic panels of different sizes.

[0036] Preferably, the photovoltaic panel connecting plate 3 has multiple mounting holes for adjusting the installation position of the photovoltaic panel by fasteners that need to be installed into the mounting holes.

[0037] The height adjustment mechanism 4 is connected between the base bracket 1 and one side of the photovoltaic panel connecting plate 3 to adjust the height of one side of the photovoltaic panel connecting plate 3.

[0038] Preferably, the height adjustment mechanism 4 includes at least one screw component, which includes a threaded rod 41 and two nuts fitted into the threaded rod 41.

[0039] The base support 1 has a vertical through-hole that mates with the threaded rod 41 on its base platform. The bottom end of the threaded rod 41 passes through the threaded hole. Two nuts are located on the top and bottom surfaces of the base platform of the base support 1, respectively, to lock the positions of the threaded rod 41 and the base platform.

[0040] The top end of the threaded rod 41 is hinged to one side of the photovoltaic panel connecting plate 3 via a ball joint or a spherical bearing.

[0041] The inclined surface of the inclined support block 2 faces the height adjustment mechanism 4, which reduces the amount of movement at the bottom of the angle adjustment mechanism 5 and improves the support reliability of the angle adjustment mechanism 5.

[0042] Angle adjustment mechanism 5 is connected between the inclined support block 2 and the photovoltaic panel connecting plate 3 on the other side.

[0043] More preferably, the base support 1 has multiple threaded holes on its base platform for each screw component to pass through.

[0044] Preferably, the angle adjustment mechanism 5 includes an electric telescopic rod driven by a motor. Both ends of the electric telescopic rod are hinged to the other side of the inclined support block 2 and the photovoltaic panel connecting plate 3 via ball joints or spherical bearings. The motor is connected to the central control system. Preferably, there are two electric telescopic rods. The electric telescopic rods can extend or retract.

[0045] The angle measurement module is used to measure the tilt angle of the photovoltaic panel connection plate 3 and send the tilt angle data to the central control system. Preferably, the angle measurement module includes a tilt sensor.

[0046] The central control system adjusts the tilt angle of the photovoltaic panel connection plate 3 via the drive angle adjustment mechanism 5. Specifically, the central control system has pre-stored local solar altitude angle data and can adjust the tilt angle of the photovoltaic panel connection plate 3 based on this data via the drive angle adjustment mechanism 5. Users can choose whether to adjust the tilt angle of the photovoltaic panel connection plate 3 based on the solar altitude angle data.

[0047] Based on local solar altitude angle data, sunrise time is set as t1, sunset time as t2, and the minimum tilt time of the photovoltaic panel each day is the moment when the solar altitude angle α occurs; the calculation unit is minutes, and the angle change of the photovoltaic panel must be within... Each time period Increase by 1 degree per minute, Each time period The temperature decreases by 1 degree per minute.

[0049] When in use, adjust the height of the threaded rod 41 relative to the base bracket. The height is adjustable but cannot be rotated. Once this part of the height is fixed, it will not be adjusted again.

[0050] The motor driving the electric telescopic pole is a servo motor that can rotate in both directions. The start and stop of the servo motor are controlled by the central control system. The angle measurement module places a tilt sensor on the photovoltaic panel connection module and transmits the measurement data to the central control system as a variable for motor start and stop control. The central control system consists of a microcontroller, a clock, and a contactor. It stores the tilt angle of the angle measurement module and receives the tilt angle of the photovoltaic panel connection plate 3 to determine the tilt angle data of the photovoltaic panel, thereby controlling the forward and reverse rotation of the servo motor.

[0051] The method for using the solar altitude angle is as follows: Pre-load the regional solar altitude angle data into the central control system. If the solar altitude angle for a given day is α, then the minimum tilt angle for that day is 90-α. The time of minimum tilt angle each day is the moment the solar altitude angle α occurs. Ideally, the starting and ending angles of the photovoltaic panel (corresponding to sunrise and sunset) should be 90 degrees. However, considering the installation error of the support frame, a reliability margin should be allowed to prevent structural damage. The preset angle of the tilt sensor is from 0 to 90-α.

[0052] Sunrise time t1, sunset time t2 (unit: minutes), calculate the adjustment time per degree for the electric regulating module. (Rounded down) minutes, the electric adjustment module is every... It starts every minute, and the angle changes to... The time period is each Add 1 degree per minute, at For each Decrease by 1 degree per minute.

[0053] Compared to the fixed installation scheme, if the installation angle of the inclined support block is β, that is, the tilt angle of the inclined support block relative to the base platform is β, and the solar altitude angle on that day is α, then the daily illumination enhancement rate η is calculated as follows:

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
