Description

Technical Field

[0001] The utility model relates to the field of photovoltaic collectors, in particular to a shrapnel antenna of a photovoltaic collector. Background Art

[0002] The shrapnel antenna of a photovoltaic collector is a form of antenna for signal transmission and reception. Its working principle is based on the radiation and reflection of electromagnetic waves. The design of the shrapnel antenna allows its plug to be directly inserted into the middle frame and then fixed by welding, thus ensuring the strength of the middle frame structure without the need for processing of the contact plane. By changing the previous contact method with the middle frame, this form of antenna improves the antenna performance and saves antenna space. Briefly speaking, the principle of the shrapnel antenna is to use the radiation and reflection of electromagnetic waves to achieve signal transmission and reception. When a signal passes through the shrapnel antenna, it will be reflected by the shrapnel and focused on a point, and then radiated out again. This process of radiation and reflection will continue to repeat until the signal reaches the receiving end or is received by the shrapnel antenna. The characteristic of the shrapnel antenna is that it can transmit and receive signals in multiple frequency bands, realizing a more flexible communication method.

[0003] In the existing shrapnel antenna, the fixing feet need to be inserted into the photovoltaic collector during use, and the antenna welding plate is welded to the photovoltaic collector through a welding machine to achieve the fixation between the shrapnel antenna and the photovoltaic collector. However, the existing shrapnel antenna of the photovoltaic collector still has the following problems during use:

[0004] In order to prevent the fixing feet of the existing shrapnel antenna from shaking left and right with the photovoltaic collector, the fixing feet and the photovoltaic collector adopt an insertion method. When the antenna welding plate falls off from the photovoltaic collector, there is a lack of stability between the fixing feet on the shrapnel antenna and the insertion slots of the photovoltaic collector, thus affecting the normal use of the shrapnel antenna. Therefore, it is very necessary to involve a shrapnel antenna of a photovoltaic collector in the existing field of photovoltaic collectors. Content of the Utility Model

[0028] The following further Figure 1 -4 will be used to further elaborate on this application.

[0029] The embodiment of this application discloses a flexible antenna of a photovoltaic collector.

One end of each guide rod 21 movably penetrates into the inner cavity 30, and an adjusting block 62 is fixedly assembled at one end of the guide rod 21. Push plates 22 are fixedly assembled at the other end of each guide rod 21. Traction grooves 70 are provided on both symmetrical side faces of the adjusting block 62. Clamping holes 71 are provided on the lower inner walls of the traction grooves 70. A connecting plate 60 is fixedly assembled on the guide rod 21.

The traction blocks 61 are located on both sides of the guide rod 21, and the top of each traction block 61 is an arc surface. The arc surface and the side plane of the traction block 61 are respectively in contact with the arc block 51 in sequence. The antenna placement board 10 is inserted into the photovoltaic collector by means of the fixed feet 20. The push plates 22 are stressed by the insertion grooves on the photovoltaic collector, so that the guide rods 21 drive the connecting plate 60 to move in the inner cavity 30. The connecting plate 60 drives the arc surface and the side plane of the traction block 61 to be respectively in contact with the arc block 51 in sequence, so that the arc block 51 is stressed and the resilient spring 52 contracts. The push rods 50 drive the clamping blocks 53 to move on the placement grooves 23, so that the clamping blocks 53 extend out from one side of the fixed feet 20, facilitating clamping in the insertion grooves on the photovoltaic collector and improving the stability between the fixed feet 20 on the antenna placement board 10 and the photovoltaic collector.

[0030] Refer to Figure 3 and Figure 4, a fixed block 31 is fixedly assembled on the inner cavity 30. An activity cavity 32 is arranged inside the fixed block 31. One end of the guiding rod 21 movably penetrates into the activity cavity 32, and the adjusting block 62 moves on the activity cavity 32. Operation cavities 33 are symmetrically arranged inside the fixed block 31 on both sides of the activity cavity 32. Clamping rods 40 are movably assembled on the operation cavities 33. One end of each clamping rod 40 movably penetrates into the activity cavity 32, and one end of each clamping rod 40 is movably assembled with a traction groove 70 respectively.

The limiting plates 43 are located on one side of the fixed block 31. Driven by the pushing of the plugging groove on the photovoltaic collector, the pushing plate 22 causes the guiding rod 21 to drive the adjusting block 62 to move on the activity cavity 32, and one end of the clamping rod 40 moves on the traction groove 70 until one end of the clamping rod 40 approaches the clamping hole 71. Under the elastic force of the telescopic spring 42, one end of the clamping rod 40 is inserted into the clamping hole 71. At this time, the moving range of the traction block 61 on the guiding rod 21 is limited, and the arc surface and the side plane of the traction block 61 are respectively attached to the arc block 51 in sequence.

At this time, the second antenna radiation plate 13 is welded to the photovoltaic collector by a welding machine.

[0032] Working principle: The antenna placement board 10 is installed on the photovoltaic collector, so that the fixed feet 20 on the antenna placement board 10 are inserted into the insertion slots of the photovoltaic collector. At this time, the second antenna radiation board 13 is welded to the photovoltaic collector by a welding machine. The push plate 22 is pushed by the insertion slots on the photovoltaic collector, so that the guide rod 21 drives the adjustment block 62 to move on the movable cavity 32. One end of the locking rod 40 moves on the traction groove 70 until one end of the locking rod 40 approaches the locking hole 71. Under the elastic force of the telescopic spring 42, one end of the locking rod 40 is inserted into the locking hole 71. At this time, the moving range of the traction block 61 on the guide rod 21 is limited. The arc surface and the side plane of the traction block 61 are respectively attached to the arc block 51 in sequence. The arc block 51 is stressed, and the elastic spring 52 contracts. The push rod 50 drives the locking block 53 to move on the placement groove 23, so that the locking block 53 extends from one side of the fixed foot 20, facilitating the clamping in the insertion slots on the photovoltaic collector, improving the stability of the fixed feet 20 on the antenna placement board 10 and the photovoltaic collector, and preventing the antenna welding board 11 on the antenna placement board 10 from detaching from the welding part with the photovoltaic collector, which affects the stability with the photovoltaic collector.
