Description

Technical Field

[0001] This utility model relates to the field of damper technology, specifically to a reverse spring force damper for a tracking photovoltaic bracket. Background Technology

[0002] A photovoltaic (PV) tracking bracket uses a rotary reducer to drive the main beam, adjusting the tilt angle of the PV modules in real time to ensure they always face the sun, thus significantly increasing the amount of solar radiation received by the PV modules. In actual operation, dampers are often installed on the columns at both ends of a single-row tracking PV bracket. The dampers ensure the smooth rotation of the main beam and, in windy conditions, also ensure greater stability of the PV bracket, preventing large swaying. Currently, because the PV panels at both ends of the PV bracket are far from the drive end, their angle is often 3-8 degrees lower than the set angle of the PV tracking bracket due to the weight of the PV modules and purlins. Therefore, overcoming the angle reduction caused by the weight of the purlins and modules is a key technical challenge that industry professionals need to overcome. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a tracking photovoltaic bracket reverse spring force damper to balance the weight of the photovoltaic panel and purlins and solve the problem of low angle.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A reverse spring force damper for a tracking photovoltaic bracket, comprising:

[0006] The damping rod includes an outer cylinder and an inner cylinder, with one end of the inner cylinder installed in the outer cylinder;

[0007] The base is located outside the outer cylinder block; the base is fixedly installed on the inner cylinder block.

[0008] The first elastic component is mounted on the base at one end and on the outer cylinder at the other end;

[0009] The second elastic component is mounted on the base, with one end connected to the outer cylinder.

[0010] When the inner cylinder moves outward from the outer cylinder, the first elastic component generates a rebound force, pulling the inner cylinder inward from the outer cylinder; when the inner cylinder moves inward from the outer cylinder, the second elastic component generates a rebound force, pushing the inner cylinder outward from the outer cylinder.

[0011] Preferably, the base includes a mounting plate and a positioning tube; the mounting plate is fixed to the outer cylinder body; both sides of the mounting plate are integrally provided with bent portions, which are perpendicular to the mounting plate; the positioning tube is fixed to the mounting plate and located between the two bent portions.

[0012] Preferably, the positioning tube is provided with a mounting hole; the positioning tube is fixed to the mounting plate by inserting a locking bolt through the mounting hole.

[0013] Preferably, the first elastic component is a tension spring.

[0014] Preferably, an upper hanging plate is fixedly installed on the outside of the outer cylinder; a lower hanging plate is fixedly installed on the positioning tube; one end of the tension spring is hung on the upper hanging plate, and the other end is hung on the lower hanging plate.

[0015] Preferably, the second elastic component is a torsion spring.

[0016] Preferably, the base further includes a rotating shaft and a cotter pin; the bent portion is provided with a shaft hole; the rotating shaft is placed between the two bent portions, with its end passing through the shaft hole and extending to the outside of the bent portion; the end of the rotating shaft is provided with a pin hole, and the cotter pin is inserted into the pin hole; a pressure plate is fixedly provided on the outer cylinder; the torsion spring is sleeved on the rotating shaft; one end of the torsion spring abuts against the pressure plate, and the other end is installed on the positioning tube.

[0017] Preferably, two torsion springs are provided; the two torsion springs are symmetrically arranged on both sides of the inner cylinder.

[0018] Preferably, the positioning tube is provided with a through hole; an inner sleeve is installed in the through hole; and the other end of the torsion spring is inserted into the inner sleeve.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] Based on the dual elastic structure of tension spring and torsion spring, the tension spring provides a pull force when stretched and the torsion spring provides a push force when compressed. The dual rebound force can specifically balance the self-weight of the photovoltaic panel module and the purlin, effectively preventing the photovoltaic bracket from being pressed down at an angle due to its own weight, ensuring the accuracy of the main beam rotation angle, and improving the stability of the photovoltaic module's solar radiation reception.

[0021] The base is fixed by mounting plates, positioning tubes and locking bolts. The tension spring is installed by hanging the upper and lower hanging plates. The torsion spring is installed by positioning the rotating shaft, cotter pin and inner sleeve. The overall structure is simple to assemble and easy to disassemble and replace tension springs, torsion springs or other parts in the later stage, reducing maintenance difficulty and cost.

[0022] The damper can be installed on any non-drive column of the main beam without the need for a fixed installation position. The installation point can be flexibly adjusted according to the construction environment and actual needs, adapting to different installation scenarios and improving the flexibility of use.

[0023] The resistance applied to the main beam can be adjusted simply by replacing the tension springs and torsion springs with different stiffnesses, without the need to modify the overall structure of the damper. It can quickly adapt to changes in the weight of photovoltaic panels and purlins, meet the usage requirements of photovoltaic brackets of different specifications, and enhance product adaptability.

[0044] Working principle

[0045] The tracking photovoltaic bracket reverse spring force damper includes a damping rod, a base, a first elastic component (tension spring 10) and a second elastic component (torsion spring 11). The damping rod consists of an outer cylinder 1 and an inner cylinder 4 with one end installed in the outer cylinder 1. The base is fixed on the inner cylinder 4 and located outside the outer cylinder 1.

[0046] When the photovoltaic main beam rotates, causing the damper to actuate, if the inner cylinder 4 moves outward from the outer cylinder 1, one end of the tension spring 10 moves with the base while the other end is fixed to the outer cylinder 1. After being stretched, it generates a rebound force, pulling the inner cylinder 4 inward from the outer cylinder 1. If the inner cylinder 4 moves inward from the outer cylinder 1, the pressure plate 2 on the outer cylinder 1 compresses the torsion spring 11, which generates a rebound force, pushing the inner cylinder 4 outward from the outer cylinder 1. These two rebound forces balance the weight of the photovoltaic panel modules and purlins, ensuring the stability of the main beam's rotation angle.
