[0021] 3 - Heat dissipation holes 4 - Cable outlet holes DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will describe the specific implementation manners of the utility model in detail with reference to the drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the utility model and are not used to limit the utility model.

[0023] In the present utility model, unless otherwise specified, the directional terms such as "side, bottom, inner, outer" included in the terms only represent the orientation of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation to the terms.

[0024] See Figure 1 , the present utility model provides a generator terminal outgoing line protective cover without an outgoing line chamber. The generator terminal outgoing line protective cover without an outgoing line chamber includes a fixed bracket 1 detachably installed on the outer wall of the wall-through bushing and a protective cover body 2 detachably installed on the fixed bracket 1. The protective cover body 2 is of a frame structure, and an organic glass plate is detachably installed on the outer facade of the frame structure. Among them, a plurality of heat dissipation holes 3 are provided on the organic glass plate located on the side of the frame structure, and a plurality of cable outgoing holes 4 are provided on the organic glass plate located on the bottom surface of the frame structure.

[0025] Through the above technical solution, when installing the generator terminal outgoing line protective cover without an outgoing line chamber, first install the fixed bracket 1 on the outer wall of the wall-through bushing, and then install the protective cover body 2 on the fixed bracket 1 to complete the fixation of the protective cover. The entire installation and disassembly process is convenient and fast. At the same time, the protective cover body 2 is of a frame structure, and an organic glass plate is detachably installed on the outer facade of the frame structure. Among them, in order to facilitate the timely dissipation of the heat inside the protective cover body 2, the present utility model provides a plurality of heat dissipation holes 3 on the organic glass plate located on the side of the frame structure (see Figure 3 ), and in order to facilitate the installation of cables, a plurality of cable outgoing holes 4 are also provided on the organic glass plate located on the bottom surface of the frame structure. In addition, the organic glass plate is a large-piece and detachable type, which can ensure the convenience and speed of daily maintenance.

[0026] In the present embodiment, it is preferable that the frame structure is made of aluminized zinc sheet. Using aluminized zinc sheet can effectively prevent the oxidation of the steel plate surface and extend the service life; at the same time, it has high mechanical strength and has the characteristics of high elasticity and high strength under conditions such as low temperature, high temperature, impact loading and vibration loading. And the surface coating has good heat reflection performance, which can reflect solar radiant heat and reduce the internal temperature. In addition, the appearance effect of the aluminized zinc sheet is also very good, beautiful and good-looking.

[0027] In the present embodiment, in order to facilitate the quick and convenient installation or disassembly of the generator terminal outgoing line protective cover without an outgoing line chamber, preferably, the frame structure is provided with reserved installation holes for fixing expansion bolts.

[0028] In order to make the organic glass plate installed and used on the generator terminal outgoing line protective cover without an outgoing line chamber have sufficient strength and effectively prevent external impacts, preferably, the thickness of the organic glass plate is 4-6 mm.

[0029] Further preferably, the thickness of the plexiglass plate is 5 mm. The plexiglass plate with such sufficient thickness is not easy to break, its service life is greatly extended, and the maintenance and use costs are virtually reduced.

[0030] When disassembling or installing the plexiglass plate, in order to simplify the operation and ensure the integrity of the exterior facade, preferably, the plexiglass plate on any side of the exterior facade is of an integral structure.

[0031] As Figure 2 shown, in this embodiment, preferably, the fixing bracket 1 is installed on the wall through bolts, and both the fixing bracket 1 and the bolts are made of hot-dip galvanized type. In this way, the hot-dip galvanized fixing bracket 1 and bolts have higher hardness and are not easily damaged, deformed or cracked. At the same time, zinc has good oxidation performance and can form a dense zinc oxide film, making the hot-dip galvanized products have better oxidation resistance, can withstand more oxidation effects and higher temperatures, and have strong corrosion resistance.

[0032] When arranging the cable inlets and outlets on the generator terminal outlet protection cover of the installed small chamber without outgoing lines, in order to prevent the edges of the relatively sharp cable outlet holes 4 from cutting and damaging the cables, seriously affecting the service life of the cables and even causing leakage risks, preferably, rounded corners are formed at the edges of the cable outlet holes 4.

[0033] In addition, as Figure 4 shown, in the actual design process, the number of ribs in the frame structure can be adjusted according to the overall size of the protection cover body 2 frame to provide sufficient support force for the relatively large integral plexiglass plate.

[0034] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0035] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.

[0036] In addition, any combination can be made between various different embodiments of the present invention, as long as it does not violate the idea of the present invention, it should also be regarded as the content disclosed by the present invention.
