Description

Technical Field

[0001] The invention relates to the field of vibration absorbers, and in particular to a photovoltaic vibration absorber. Background Art

[0002] Photovoltaic vibration dampers are mainly used in solar photovoltaic systems. When photovoltaic panels vibrate due to strong winds, the vibration dampers form damping forces at different speed points to suppress the vibration of photovoltaic panels, play a balancing and stabilizing role, and effectively resist wind pressure and wind vibration. Traditional photovoltaic vibration dampers are prone to damage and failure during use. The reason is that due to structural design defects, the horizontal shear force of traditional photovoltaic vibration dampers is too large when the vibration dampers are working, and the stroke of the vibration dampers is unstable, so they are easy to damage. At the same time, traditional photovoltaic vibration dampers also have unreasonable supporting structures. After damage, the staff cannot be informed in time, which may lead to more serious consequences.

[0003] Therefore, it is necessary to solve the above problems. Summary of the invention

[0004] In view of the above problems, the present invention provides a photovoltaic vibration absorber, which can provide a longer service life and can promptly alarm when a fault occurs, and can well meet the needs of the solar photovoltaic industry system. The technical solution adopted by the present invention is as follows:

[0005] A photovoltaic shock absorber comprises a shock absorber and a sleeve, wherein the shock absorber is arranged inside the sleeve, wherein the shock absorber comprises a connecting rod piston assembly, a cylinder bottom valve assembly, an oil barrel assembly, a dust cover assembly and a spherical bearing, the connecting rod piston assembly comprises a connecting rod, the dust cover assembly comprises a dust cover and a dust cover, the connecting rod is connected to the spherical bearing, one end of the connecting rod connected to the spherical bearing is milled flat and connected by threaded tightening, a corresponding adaptive hole is opened on the dust cover for the connecting rod to pass through, the outer surface of the dust cover is uniformly provided with circular holes along the circumferential direction, balls are arranged in the holes, the inner surface of the sleeve is provided with a slide groove along the radial direction of the sleeve, and the ball is slidably connected to the slide groove.

[0006] Furthermore, a travel sensor and a buzzer are installed at both ends of the sleeve, and the travel sensor and the buzzer are connected through an electrical circuit.

[0007] Furthermore, end covers are detachably fixed to both ends of the sleeve, and holes for the spherical bearing to pass through are formed on the end covers.

[0008] Furthermore, the ball has two types, large and small, which respectively correspond to the connection between the dust cover and the sleeve of different diameters on the shock absorber.

[0009] Furthermore, the cylinder bottom valve assembly includes a valve system gasket, and the valve system gasket is prepared by SPCC and carburized.

[0010] Furthermore, at least two groups of holes and balls are respectively arranged along the circumferential direction of the dust cover, and at least two groups of sliding grooves inside the sleeve are also correspondingly arranged.

[0011] Furthermore, the dust cover and the dust cap are fixedly connected by spot welding.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In the present invention, a sleeve is arranged outside the dust cover of the shock absorber, and the shock absorber and the dust cover are connected by ball sliding, so that the shock absorber stroke is standardized and the shock absorber is not easily damaged. At the same time, an alarm device is added. When the shock absorber fails and the stroke is insufficient, the staff can be notified in time for maintenance.

[0014] 2. In the present invention, the valve system gasket inside the shock absorber is prepared by SPCC and carburized, which avoids the problem of parts deformation caused by excessive pressure inside the shock absorber, thereby causing a decrease in damping force, and meets the product performance requirements.

[0015] 3. In the present invention, the connection position of the connecting rod and the spherical bearing is milled flat, which further improves the connection stability and overcomes the defects of welding and fixing the connecting rod and the dust cover in the traditional shock absorber, thereby ensuring the service life of the product and improving safety.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 4 The present invention provides a shock absorber that meets the needs of a solar photovoltaic industry system, including a shock absorber 1 and a sleeve 2. The shock absorber 1 is arranged inside the sleeve 2, wherein the shock absorber 1 includes a connecting rod piston assembly, a cylinder bottom valve assembly, an oil barrel assembly, a dust cover assembly and a spherical bearing 3. The connecting rod piston assembly includes a connecting rod 4, and the dust cover assembly includes a dust cover 5 and a dust cover 6. The connecting rod 4 is connected to the spherical bearing 3. One end of the connecting rod 4 connected to the spherical bearing 3 is milled flat and tightened by threads. An adaptive hole is correspondingly opened on the dust cover 5 for the connecting rod 4 to pass through. The outer surface of the dust cover 6 is evenly provided with circular holes along the circumferential direction, and a ball 7 is arranged in the hole. The inner surface of the sleeve 2 is provided with a slide groove along the radial direction of the sleeve 2, and the ball 7 is slidably connected to the slide groove.

[0024] A travel sensor 8 and a buzzer 9 are installed at both ends of the sleeve 2, and the travel sensor 8 and the buzzer 9 are connected through an electrical circuit.

[0025] End covers 10 are detachably fixed to both ends of the sleeve 2 , and a hole for the spherical bearing 3 to pass through is formed on the end cover 10 .

[0026] The balls 7 have two sizes, large and small, which are respectively adapted to the connection between the dust cover 6 and the sleeve 2 of different diameters on the shock absorber 1 .

[0027] The cylinder bottom valve assembly includes a valve system gasket 11, and the valve system gasket 11 is made of SPCC and carburized.

[0028] At least two groups of holes and balls 7 are respectively arranged along the circumferential direction of the dust cover 6 , and at least two groups of sliding grooves inside the sleeve 2 are also correspondingly arranged.

[0029] The dust cover 6 and the dust cover 5 are fixedly connected by spot welding.

[0030] The technical principles adopted by the present invention are as follows:

[0031] The present invention innovates the structure of the traditional shock absorber that is easily damaged. A sleeve is arranged outside the dust cover to regulate the travel route of the shock absorber to prevent the shock absorber from being deformed due to shaking left and right. Alarm devices are arranged on both sides of the sleeve. The travel sensor detects the travel range of the shock absorber. When the shock absorber fails to meet the specified travel range, a buzzer alarm is triggered to inform the operator to repair in time.

[0032] The maximum damping force of the photovoltaic shock absorber at a low speed of 0.05m / s is 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. The internal pressure is 11-24.94MPa, so choosing a suitable recovery and compression valve system is the key to achieving a large damping force. The key to ensuring the normal operation of the valve system is the gasket of the valve system. Due to the high internal pressure, the general valve system cannot withstand the pressure. When the power is demonstrated, the corresponding parts will be deformed, resulting in a decrease in damping force. After repeated tests, the present invention selects SPCC as the manufacturing material and carburizes the gasket. After treatment, the damping force is stable and meets the product performance requirements.

[0033] The improvement in the connection method between the dust cover assembly and the shock absorber in the present invention reduces the risk of breakage that may be caused by welding with the connecting rod. In the traditional connection method, the dust cover and the connecting rod are fixed by welding, and the connecting rod and the dust cover are welded in a circle for one week. After the product is assembled, the joint bearing is tightened on the connecting rod thread, and then the dust cover is spot welded. There is a risk of breakage in welding; in the present invention, the connecting rod is milled flat, and a dust cover that matches the shape of the connecting rod is used to avoid welding between the connecting rod and the dust cover, and then the dust cover is spot welded to the dust cover. After the product is assembled, the joint bearing is tightened on the connecting rod thread.

[0034] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the protection scope of the present invention.
