Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power stations, in particular to an adjusting support for a cable bridge in a subsidence area. Background Art

[0002] The statements in this section merely mention the background technology related to the present invention and do not necessarily constitute the prior art.

[0003] Currently, the site selection for photovoltaic and other new energy sources is becoming increasingly poor, with many sites located in coal mining subsidence areas. Due to the block-based power generation and centralized grid connection characteristics of photovoltaic power stations, the site's box-type transformers are connected via cables to the 35kV distribution room of the booster station. The collection lines in subsidence areas are typically laid using a combination of direct burial and cable trays. Due to the impact of coal mining subsidence, the site's ground has experienced numerous collapse pits and gullies. For ease of construction, photovoltaic sites currently utilize a fixed support scheme of prestressed concrete piles (PHC) and cable trays for collection lines crossing gullies. However, due to the significant ground subsidence, the overhead collection line cable trays often experience significant distortion, resulting in partial cable breakage and significant losses to the photovoltaic site. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the utility model provides a cable tray adjustment support in a subsidence area, the purpose of which is to provide a cable tray support with adjustable height to avoid cable distortion and local cable breakage caused by ground subsidence.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A cable tray adjustment support in a subsidence area includes a column mounted on a pile foundation, a bridge support beam fixed on the top of the column, an upper adjustment margin space and a lower adjustment margin space reserved inside the column, a column connector arranged between the upper adjustment margin space and the lower adjustment margin space, a height adjustment hole arranged inside the column, and the column connector and the height adjustment hole are cooperatively connected.

[0007] As an embodiment, the inner wall of the column is fixed with a connecting hoop, and the connecting hoop is sleeved on the pile foundation. The connecting hoop includes two semicircular hoops of the same structure. Several pairs of connecting bolts are set at the connection between the two ends of the two semicircular hoops of the same structure, and are connected with the bolt connection holes reserved on the semicircular hoops.

[0008] As an embodiment, the connecting clamp includes at least one. When multiple connecting clamps are included, adjacent connecting clamps are arranged at preset intervals.

[0009] As an implementation manner, the upper adjustment margin space and the lower adjustment margin space are determined according to the settlement amount provided by the steady settlement report.

[0010] As an embodiment, an adjusting bolt is provided on the column connecting member, and the adjusting bolt is connected to the bolt connecting hole.

[0011] As an embodiment, the adjusting bolt is a hexagonal bolt.

[0012] As an embodiment, the height adjustment holes are evenly distributed on the inner wall of the column where the upper adjustment margin space and the lower adjustment margin space are located.

[0013] As an embodiment, the columns and the bridge support beams are fixed by hexagonal bolts.

[0014] As an embodiment, when the column connector is fixed, the column connector is located on the symmetry axis of two semicircular hoops of the same structure.

[0015] As an implementation method, the diameter of the two semicircular hoops of the same structure is 300 mm.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] With this cable tray adjustment support, when the bridge sinks or rises, the bolts connecting the clamp and the pile foundation are loosened on-site. The clamp connection height is adjusted up or down according to the amount of sinking or rising. At the same time, the column connector is adjusted to the corresponding height adjustment bolt hole of the column. This allows the cable tray to deform in response to ground settlement without human intervention, thus preventing cable breakage. The structure is simple, construction is convenient, and operation and maintenance are convenient, saving operation and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
