Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Referring to FIG. 1 to FIG. 4 , the present invention provides a shock absorber satisfying the solar photovoltaic industry system, including a shock absorber 1 and a casing 2 , the shock absorber 1 is arranged inside the casing 2 , wherein the shock absorber 1 includes Connecting rod piston assembly, cylinder bottom valve assembly, oil cylinder assembly, dust cover assembly and joint bearing 3, the connecting rod piston assembly includes a connecting rod 4, the dust cover assembly includes a dust cover 5 and a dust cover Cover 6, the connecting rod 4 is connected with the joint bearing 3, the end of the connecting rod 4 connected with the joint bearing 3 is milled flat and connected by screwing, and the dust cover 5 is correspondingly provided with a matching hole for the connecting rod 4 Through, the outer surface of the dust cover 6 is evenly provided with circular holes along the circumferential direction, the holes are provided with balls 7, and the inner surface of the sleeve 2 is provided with a chute along the radial direction of the sleeve 2, so The balls 7 are slidably connected with the chute.

In the present invention, innovation is made on the structure that is easily damaged in the traditional shock absorber. A sleeve is arranged outside the dust cover to standardize the travel route of the shock absorber, so as to avoid the structural deformation of the shock absorber due to the left and right shaking. An alarm device is installed on the side, and the stroke sensor detects the stroke range of the shock absorber. When the shock absorber fails to meet the specified stroke, the buzzer alarm is triggered, and the operator is notified in time for maintenance;

The recovery and compression maximum damping force of the photovoltaic shock absorber at a low speed of 0.05m/s reaches about 3900N, which is about 20 times the damping force of the truck shock absorber, and is higher than the damping force of the car shock absorber; its internal pressure In the range of 11-24.94MPa, it is the key to achieve a large damping force to select the appropriate recovery and compression valve system, and the gasket of the key valve system to ensure the normal operation of the valve system, due to the large internal pressure, the general valve system cannot withstand its When the power is displayed, the corresponding parts will be deformed, which will cause the damping force to drop.
