[0030] Box-type substation, also known as prefabricated substation or prefabricated substation. It is a kind of factory prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme, including high-voltage switchgear, distribution transformer and low-voltage distribution device. It combines the functions of transformer step-down and low-voltage distribution organically, and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable steel structure box. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after the civil construction substation. Box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil construction distribution room and distribution station and becomes a new type of complete set of power distribution equipment. Box-type substation is mainly composed of electrical units such as multi-circuit high-voltage switch system, armored busbar, substation integrated automation system, communication, telecontrol, metering, capacitor compensation and DC power supply.

[0031] In the related art, the blade spacing of the shutters on the box-type substation is 60mm, and small birds can fly into the box-type substation through the shutters, causing unpredictable safety hazards and accidents. Generally, a wire mesh is set on the shutters to prevent birds from entering, but the wire mesh is generally fixed with bolts, which is cumbersome and complicated to disassemble.

[0032] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a box-type substation shutter to prevent birds from flying in. When the wire mesh 22 needs to be removed, it is only necessary to pull the pull rod 27 to drive the clamping block 26 to disengage from the inside of the clamping slot 23, retract to the inside of the slot body 24 and squeeze the spring 25 to release the fixation of the wire mesh 22. The sliding wire mesh 22 can be slid out from the inside of the limit plate 21 to complete the removal. The design of the wire mesh 22 can prevent small birds from entering the interior of the box-type substation 11 through the gap of the shutter 12 and causing damage to the internal electronic components.

[0033] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0034] Combination Figure 1-Figure 5The embodiment of the present application provides a box-type substation shutter structure to prevent birds from flying in, including: a box-type substation 11, a shutter 12 is arranged on the outside of the box-type substation 11; a blocking component 2 is arranged on the outside of the box-type substation 11, and the blocking component 2 includes: a limit plate 21 is symmetrically arranged on the outer wall of the box-type substation 11; a wire mesh 22 is slidably arranged on the inner side of the limit plate 21; a slot 23 is opened on the outer wall of the wire mesh 22; a slot body 24 is opened on the inner wall of the limit plate 21; a spring 25 is arranged inside the slot body 24; a block 26 is arranged at one end of the spring 25 and is engaged with the slot 23; one end of a pull rod 27 passes through the limit plate 21, and passes through the spring 25 to connect with the block 26.

[0035] Specifically, the two ends of the spring 25 are fixed to the clamping block 26 and the inner wall of the groove body 24 by a clamping ring. The fixing method of the clamping ring belongs to the existing well-known technology and is not described in detail here. The pull rod 27 and the clamping block 26 are fixed by welding.

[0036] When the wire mesh 22 needs to be cleaned during use, first pull the pull rod 27 to drive the block 26 to disengage from the inside of the slot 23, retract into the inside of the slot body 24 and squeeze the spring 25 to release the fixation of the wire mesh 22, and then slide the wire mesh 22 out of the inner side of the limit plate 21 to complete the disassembly. After cleaning, when installing it, you only need to pull the pull rod 27 and push the wire mesh 22 to slide and install it to the inner side of the limit plate 21 until the slot 23 and the slot body 24 are aligned, release the pull rod 27 and the spring 25 pushes the block 26 to engage and fix with the slot 23 to complete the installation of the wire mesh 22.

[0037] In some embodiments, the blocking assembly 2 further includes: a pull block 28 disposed at one end of the pull rod 27 .

[0038] When in use, the setting of the pulling block 28 facilitates the application of force, so it is easier to pull the pulling rod 27.

[0039] In some embodiments, the bottom of the block 26 and the inner wall of the slot 23 are inclined.

[0040] When in use, the inclined design allows the wire mesh 22 to be installed by sliding it to the inner side of the limit plate 21. When sliding upward, the block 26 will be squeezed so that the block 26 retracts into the interior of the groove 24 until it is engaged and fixed with the groove 23 to complete the installation of the wire mesh.

[0041] In some embodiments, the blocking assembly 2 further includes: a cross bar 29 disposed on the top of the limiting plate 21 .

[0042] When in use, the provision of the cross bar 29 can prevent the wire mesh 22 from continuing to move upward after being fixed and thus from being separated from the limiting plate 21 .

[0043] In some embodiments, the outer wall of the block 26 fits with the inner wall of the slot 24 .

[0044] When in use, the block 26 can be made more stable when sliding.

[0045] In some embodiments, a handle 31 is provided at the bottom of the wire mesh 22 .

[0046] When in use, the handle 31 can conveniently pull the wire mesh 22, making it easier to replace the wire mesh 22.

[0047] In some embodiments, the outer side wall of the wire mesh 22 is provided with balls 32 .

[0048] When in use, when the wire mesh 22 slides inside the limiting plate 21, the arrangement of the balls 32 can reduce the friction force, thereby making the sliding smoother.

[0049] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0050] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
