Description

Support fixed knot and construct and photovoltaic tracking installing the system

Technical Field

The utility model relates to a sheet metal supports the field, especially relates to a support fixed knot and photovoltaic tracking installing the system.

Background

The current photovoltaic (or photothermal) tracking support is an important light energy acquisition device, but the current photovoltaic tracking support has a problem that when windy weather is met (wind power is less than five levels), components on the support can generate torsion and load vibration to a main shaft under the action of the pressure difference of wind. Because the action point of the acting force is only one point or a plurality of points, under severe conditions, the whole tracking system can resonate, so that the components are damaged, and the mechanical structure of the tracking bracket is damaged.

In order to avoid damaging the tracking support by wind (wind power is less than five levels), a vibration-avoiding support is arranged on the tracking support, the vibration-avoiding support can generate a reaction force which changes along with the linear speed of vibration of the photovoltaic module caused by wind pressure, the swinging amplitude of the module is reduced, but the vibration-avoiding support cannot completely stop swinging and is only useful when the wind power is less than five levels. When the assembly meets the stormy weather (the wind power is more than six levels), the wind pressure on the two sides of the assembly is increased, the assembly cannot be fixed due to the telescopic characteristic of the vibration-avoiding support device, and the assembly swings along with the wind, so that the assembly is thoroughly blown down by the stormy wind.

In summary, in order to prevent the photovoltaic (or photothermal) tracking bracket from being damaged in windy weather and stormy weather, a device must be installed on the photovoltaic (or photothermal) tracking bracket, and the device can ensure that the device can play a role of buffering like a vibration-avoiding support in windy weather (wind power is less than five levels) and can play a role of fixing the assembly in stormy weather (wind power is greater than six levels).

The specific implementation mode is as follows:

the present invention will be described in detail with reference to the accompanying drawings.

Example 1

As shown in fig. 1, a damping device includes a housing 103 and a valve rod 101, the valve rod 101 penetrates through the housing 103, and the valve rod 101 and the housing 103 are in sliding sealing fit together, and further includes an inner casing 105, a plunger rod 106 and a motor head assembly 107, the inner casing 105 is disposed in the housing 103, the inner casing 105 divides the space in the housing 103 into a first casing 111 and a second casing 112 which are independent and communicated, one end of the valve rod 101 and the second casing 112 are in sliding sealing fit together, the valve rod 101 divides the second casing 112 into two independent and variable-volume sub-chambers 11201, a plug hole is opened on the housing 103, the plunger rod 106 is directly or indirectly in sliding sealing fit on the plug hole, the motor head assembly 107 is disposed on the outer wall of the housing 103, and the motor head assembly 107 is used for driving the plunger rod 106 to move; when the plunger rod 106 is located in the first housing cavity 111, the plunger rod 106 divides the first housing cavity 111 into two separate compartments. The power head assembly 107 is connected to a power line 108 for supplying power to the power head assembly 107.

Compared with a traditional liquid medium damping rod, in the device, an inner shell plate 105 is arranged in a shell 103, the inner space of the shell 103 is divided into a first shell cavity 111 and a second shell cavity 112 which are independent and communicated, one end of a valve rod 101 is matched with the cavity wall of the second shell cavity 112 in a sliding and sealing mode, convection of damping liquid 104 on two sides of the valve rod 101 is achieved through the first shell cavity 111, a plunger rod 106 can cut off or communicate the first shell cavity 111 through self movement, when the first shell cavity 111 is cut off, liquid on two sides of the valve rod 101 cannot be subjected to convection, the valve rod 101 cannot move continuously, when the plunger rod 106 moves again and breaks through the first shell cavity 111 and the second shell cavity 112 again, the damping liquid 104 on two sides of the valve rod 101 can be subjected to convection again, and the valve rod 101 can move again.

Referring to fig. 1, it is further stated that when the plunger rod 106 does not block the first housing chamber 111, there is a limit to the rightward movement of the valve stem 101 (i.e., there is a limit to the compression), because when the valve stem 101 is moving rightward, the damping fluid in the right-side sub-chamber 11201 flows into the left-side sub-chamber 11201, but the volume of the valve stem 101 entering the housing 103 increases, causing squeezing (compression of the damping fluid) of the damping fluid in the housing 103, and because there is a limit to the compression of the damping fluid, there is a limit to the rightward movement of the valve stem 101. Similarly, when the plunger rod 106 separates the first housing cavity 111 and the valve rod 101 moves rightwards again, the damping liquid in the right sub-cavity 11201 cannot flow but is compressed by a part, and at this time, the valve rod 101 moves rightwards for a part of distance but cannot move rightwards continuously; similarly, when the valve stem 101 moves to the left, it cannot move further to the left because of the negative pressure in the right sub-chamber 11201.

The device divides the interior of the shell 103 into two independent and communicated first shell cavity 111 and second shell cavity 112 through the arrangement of the inner shell plate 105, and controls the on-off of the damping liquid 104 on two sides of the valve rod 101 by the movement of the plunger rod 106, thereby realizing the dual functions of buffering and supporting and realizing convenient and rapid conversion.
