Description

Technical Field

[0001] The utility model relates to a photovoltaic tracker, in particular to a photovoltaic control box and a photovoltaic tracker. Background Art

[0002] A photovoltaic tracker is a photovoltaic support system that can accurately track the sun's real-time trajectory and is widely used in the field of photovoltaic power generation.

[0003] The control box is a key component of a photovoltaic tracker. This Chinese utility model patent, with publication number CN221042689U and publication date May 28, 2024, discloses a wind-solar hybrid photovoltaic control box. The box comprises a mounting plate with a connecting plate fixed to its rear surface. The photovoltaic control box body is mounted on the top surface of the mounting plate near the front end. A placement plate is fixed to the left side of the mounting plate, and a wind direction sensor is mounted on the top surface of the placement plate. This utility model utilizes solar panels to power the photovoltaic control box body in sunlight and a wind turbine body to power the control box body in windy conditions. The wind direction sensor and adjustment mechanism sense wind direction and adjust the direction of the wind turbine body, enabling smooth operation of the wind turbine body in windy conditions. The complementary use of the solar panels and wind turbine body improves the utilization of both solar and wind energy resources. However, its drawbacks are that the photovoltaic control box body is rectangular, typically requiring injection molding or casting, which can result in high costs, and the mounting plate has poor misalignment.

[0043] Specifically, the outer shell 1 is used to carry batteries, circuit boards, etc. Since the outer shell 1 is a tube, the outer shell 1 does not need to be specially injection molded or cast. It only needs to cut the existing tube into a suitable length, which is convenient for low cost and good economy. Among them, the outer shell 1 can be specifically made of aluminum alloy tubes or plastic tubes, etc.; the two end covers 2 are used to cover the outer shell 1 to prevent external dust, particles and other debris from damaging the batteries and circuit boards in the outer shell 1; the battery is used to supply electrical energy to the circuit board, and the battery can be a lithium battery or a lead-acid battery, etc., preferably a lithium battery; the circuit board is used as the control center of the photovoltaic control box of this application.

[0044] Further, such as Figure 1-2 The battery and the circuit board are connected to the housing 1 through two mounting brackets 3 respectively. The two mounting brackets 3 facilitate the independent installation of the battery and the circuit board, thereby preventing the battery and the circuit board from interfering with each other.

[0045] Further, such as Figure 3 The mounting frame 3 includes: a mounting bottom cover 31 that contacts the inner wall of the shell 1; a handle 32 connected to the mounting bottom cover 31; wherein the handle 32 is connected to the battery or circuit board, and the handle 32 is connected to the shell 1.

[0046] Specifically, the mounting bottom cover 31 is used to interfere with the inner wall of the outer shell 1, so that the inner wall of the outer shell 1 can produce a radial limiting effect on the mounting bottom cover 31, thereby facilitating the inner wall of the outer shell 1 to produce a radial limiting effect on the mounting bracket 3; the handle 32 facilitates the staff to take out and put the mounting bracket 3 into the outer shell 1, and the handle 32 is also used to carry batteries or circuit boards. The handle 32 is also used to connect with the outer shell 1, so as to facilitate fixing the mounting bracket 3 in the outer shell 1, thereby facilitating fixing the batteries or circuit boards in the outer shell 1.

[0047] Further, such as Figure 3The handle 32 includes a first plate 321, a second plate 322 and a third plate 323 connected in sequence. The first plate 321 is also connected to one end of the mounting bottom cover 31, and the third plate 323 is also connected to the other end of the mounting bottom cover 31. The battery or circuit board is connected to the mounting bottom cover 31, and the battery or circuit board is also connected between the first plate 321 and the third plate 323. The first plate 321 and the third plate 323 are respectively connected to the inner sides of the shell 1.

[0048] Specifically, the mounting bottom cover 31, the first plate 321 and the third plate 323 are used to jointly carry the battery or circuit board, and are also used to jointly connect with the interior of the shell 1, so that the handle 32 is connected to the shell 1; the second plate 322 makes it convenient for the staff to take the handle 32 out and put it into the shell 1; the first plate 321, the second plate 322 and the third plate 323 can be specifically made of sheets bent into rectangles, and then the rectangular sheets and the mounting bottom cover 31 are welded, which is convenient for low cost and good economy.

[0049] Further, such as Figure 1-3 , also includes: a first mounting hole 3211 and several second mounting holes 3212 provided on the first plate body 321; a third mounting hole 3231 and several fourth mounting holes 3232 provided on the third plate body 323; a first side wall hole 11 and a second side wall hole 12 respectively provided on both sides of the shell 1; wherein the first side wall hole 11 corresponds to the first mounting hole 3211, and the second side wall hole 12 corresponds to the third mounting hole 3231.

[0052] Specifically, the end cover body 21 is used to cover the outer shell 1 to prevent external dust, particles and other debris from damaging the battery and circuit board in the outer shell 1; the first threading hole 211 is used to pass the control line in the outer shell 1; because the extension 22 and the end of the outer shell 1 are in conflict, the end of the outer shell 1 has an axial limiting effect on the extension 22, and then the end of the outer shell 1 has an axial limiting effect on the end cover 2. Since the outside of the extension 22 is flush with the outside of the outer shell 1, it is convenient to make the overall outside of the photovoltaic control box of this application have good flatness.
