Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic grid-connected metering cabinets, specifically a photovoltaic grid-connected metering cabinet. Background Technology

[0002] A photovoltaic grid-connected metering cabinet is a power distribution device used in distributed photovoltaic power generation systems. It connects the photovoltaic power station to the power grid and has both power metering and system protection functions. It can measure the power generation of the photovoltaic power generation system and ensure the accuracy of power metering.

[0003] As disclosed in announcement number CN221862232U, a photovoltaic grid-connected metering cabinet includes a cabinet body. The cabinet body's inner cavity has multiple evenly distributed carrier plates. Connecting plates are connected to the bottom sides of each carrier plate. The side walls of the connecting plates are connected to the inner cavity side walls of the cabinet body. A limiting groove is formed at the top of the connecting plate, and a matching limiting slider is inserted into the inner cavity of the limiting groove. The top of the limiting slider is fixedly connected to the bottom of the carrier plate at a corresponding position. This utility model connects the carrier plate to the limiting slider in the limiting groove at the top of the connecting plate, thereby installing the metering element on the carrier plate. In case of a fault, pulling the carrier plate allows it to move to the outside of the cabinet body under the limiting slider's limitation, facilitating inspection and maintenance and improving the convenience of inspection and maintenance operations.

[0004] However, existing technologies have problems such as the fixed positions of partitions in the cabinet, making it inconvenient to adjust the spacing between partitions according to actual application needs, and the lack of components for securing and fixing wire harnesses in the cabinet. For example, the comparative patents listed above have this problem.

[0005] To address these issues, we propose a photovoltaic grid-connected metering cabinet. Utility Model Content

[0006] The purpose of this utility model is to provide a photovoltaic grid-connected metering cabinet to solve the problems mentioned in the background art, such as the fixed position of the partitions in the cabinet, the inconvenience of adjusting the spacing between the partitions according to actual application needs, and the lack of components for securing and fixing wire harnesses in the cabinet.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic grid-connected metering cabinet, comprising a metering cabinet body, an insulating partition, and a wiring hole;

[0008] Also includes:

[0009] The metering cabinet is equipped with multiple insulating partitions that can be moved up and down to adjust the spacing. The left and right ends of the inner side of the metering cabinet are fixedly connected to fixed columns, and the insulating partitions and fixed columns form an up-and-down sliding structure.

[0010] The bottom inner side of the metering cabinet is provided with a protective sleeve that corresponds one-to-one with the wire holes and is used to protect the wire harness. The protective sleeve consists of a rear bowl-shaped elastic sleeve fixed to the rear inner side of the lower end of the metering cabinet, a front bowl-shaped elastic sleeve attached to the front end of the rear bowl-shaped elastic sleeve, and a protective rubber ring fixed to the inner upper end of the rear bowl-shaped elastic sleeve and the front bowl-shaped elastic sleeve.

[0011] Preferably, the inner side of the fixing column is provided with fixing holes at equal intervals.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 The present invention provides the following technical solution:

[0031] To address the issues in existing technologies where the positions of partitions in the cabinet are mostly fixed, making it inconvenient to adjust the spacing between partitions according to actual application needs, and the lack of components for securing wire harnesses, this solution provides a photovoltaic grid-connected metering cabinet. The cabinet comprises a metering cabinet body 1, insulating partitions 4, and wiring holes 9. The metering cabinet body 1 contains multiple adjustable insulating partitions 4, and fixed posts 2 are fixedly connected to the left and right ends of the inner side of the metering cabinet body 1. The insulating partitions 4 and the fixed posts 2 form a sliding structure. Protective sleeves, corresponding one-to-one with the wiring holes 9, are provided at the bottom inner side of the metering cabinet body 1 to protect the wire harnesses.

[0032] The metering cabinet 1 is completely identical to existing photovoltaic grid-connected metering cabinets and belongs to existing conventional technology, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both the left and right ends of the inner side of the metering cabinet 1 are fixedly connected to the fixing posts 2, and the inner side of the fixing posts 2 is provided with fixing holes 3. At the same time, multiple insulating partitions 4 are provided in the metering cabinet 1. When it is necessary to adjust the position of the insulating partitions 4 in the metering cabinet 1 according to the usage requirements, the fixing ring 8 can be pulled. The fixing ring 8 drives the fixing connecting pin 7 to move in and out of the connecting plate 5. At the same time, the fixing connecting pin 7 compresses the spring 6, causing the spring 6 to undergo elastic deformation. At this time, the fixing connecting pin 7 moves out of the fixing hole 3, thereby releasing the limit between the insulating partition 4 and the fixing post 2. Then, the insulating partition 4 can be pulled up or down, and the insulating partition 4, together with the connecting plate 5 and the fixing post 2, can slide up and down, so as to facilitate the adjustment of the spacing between adjacent insulating partitions 4. After the position adjustment is completed, the fixing ring 8 can be released directly. At this time, the spring 6 returns to its elastic deformation, pushing the fixing connecting pin 7 to be inserted into the fixing hole 3 at the corresponding position, thereby facilitating the fixing of the insulating partition 4.

[0033] like Figure 2 , Figure 5 and Figure 6As shown, a wire hole 9 is provided at the bottom of the metering cabinet 1. The wire harness passes through the wire hole 9 into the metering cabinet 1. Combined with the protective sleeve, the protective sleeve and the wire hole 9 are configured in a one-to-one correspondence. The protective sleeve consists of a rear cup-shaped elastic sleeve 10 fixed to the inner rear of the lower end of the metering cabinet 1, a front cup-shaped elastic sleeve 11 fitted to the front end of the rear cup-shaped elastic sleeve 10, and a protective rubber ring 12 fixed to the inner upper end of the rear cup-shaped elastic sleeve 10 and the front cup-shaped elastic sleeve 11. After the wire harness passes through the wire hole 9, it is simultaneously inserted into the rear cup-shaped elastic sleeve 10. Move the connecting rod 14 backward, and the connecting rod 14 slides in the auxiliary plate 15. The connecting rod 14, together with the connecting post 13, drives the front cup-shaped elastic sleeve 11 to move backward, so that the front cup-shaped elastic sleeve 11 fits against the front side of the rear cup-shaped elastic sleeve 10. The wire harness can be clamped, positioned and protected by the rear cup-shaped elastic sleeve 10 and the front cup-shaped elastic sleeve 11. The wire harness is also fitted with the protective rubber ring 12 at the upper end of the rear cup-shaped elastic sleeve 10 and the front cup-shaped elastic sleeve 11. Then, rotate the connecting bolt 16 to limit the distance between the auxiliary plate 15 and the connecting rod 14.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
