Description

Technical Field

[0001] This utility model relates to the field of drainage equipment technology, specifically to a drainage device for a concave swampy area in a photovoltaic plant. Background Technology

[0002] When constructing photovoltaic plants, it's inevitable to encounter situations involving swampy areas. Drainage structures are a crucial design factor when working in swampy terrain, as these areas typically have high water levels and moist soil, and are more prone to forming swamps in slightly concave areas. This poses challenges to the construction process and the stability of the final project. For example, when building bridges across swampy areas, engineers often employ a series of drainage measures to ensure the bridge's foundation is stable and prevent settlement. By comprehensively utilizing drainage structures and methods, effectively managing the moisture in swampy areas ensures smooth construction and long-term project stability.

[0003] Existing drainage structures draw out and discharge underground seepage water by digging pits, but the drainage efficiency is poor and the structures are unstable and prone to collapse. The pits need to be dug again to draw out the water, which consumes too much manpower and resources and has low work efficiency.

[0004] Therefore, a drainage device for the swampy area in the concave region of a photovoltaic plant is proposed. Utility Model Content

[0007] The pit is located in a concave area of ​​the swamp.

[0008] The connecting structure includes a left connecting part and a right connecting part; the left connecting part includes a first connecting plate, a baffle, and a telescopic rod; the first connecting plate is located at the bottom left side of the pit; the telescopic rod is inclined, with its bottom hinged to the first connecting plate and its top hinged to the upper part of the baffle; the baffle is located on the left side of the pit and is used to abut against the left side wall of the concave area; the right connecting part has the same structure as the left connecting part and is located on the right side of the pit and is used to connect and abut against the right side wall of the concave area.

[0009] The filter box is installed inside the pit, with a connecting pipe at the bottom, and a filter screen assembly inside the filter box.

[0010] The water pump is located at the top of the pit, connected to the top of the filter box via a pumping pipe, and connected to an external water storage tank via a delivery pipe.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0026] like Figures 1-5 As shown, a drainage device for a concave swampy area in a photovoltaic plant includes a pit body 1, a connecting structure, a filter box 3, and a water pump 4.

[0027] Pit 1 is located in a concave area of ​​the swamp.

[0028] The connecting structure includes a left connecting part 21 and a right connecting part 22. The left connecting part 21 includes a first connecting plate 211, a baffle 212, and a telescopic rod 213. The first connecting plate 211 is located at the bottom left side of the pit body 1. The telescopic rod 213 is inclined and hinged at the bottom to the first connecting plate 211 and at the top to the upper part of the baffle 212. The baffle 212 is located on the left side of the pit body 1 and is used to abut against the left side wall of the concave area. The right connecting part 22 has the same structure as the left connecting part 21 and is located on the right side of the pit body 1. It is used to connect and abut against the right side wall of the concave area.

[0029] Filter box 3 is installed inside pit 1, with connecting pipe 31 at the bottom, and filter screen group is installed inside filter box 3.

[0030] Water pump 4 is located at the top of pit 1, connected to the top of filter box 3 via water pumping pipe 41, and connected to external storage water tank via water delivery pipe 42.

[0031] When using this device, the low-lying swampy area may have concave regions. During construction, a pit 1 is set up in the concave region. The pit 1 is similar to a foundation pit, enclosed on all four sides. The bottom or side walls of the pit 1 are not sealed. Groundwater seepage from the swampy area is introduced into the pit 1 for storage and accumulation. The left and right ends of the pit 1 are connected by a left connecting part 21 and a right connecting part 22. The telescopic rod 213 is activated to push the baffle 212 to the left and right sides respectively to press against the side walls of the concave region for fixation, which improves the stability of the pit structure and avoids edge collapse. This solves the problem of having to re-excavate and divert water after collapse. After the device is fixed, the water pump 4 is started to pump water. The accumulated water enters the filter box 3, is filtered by the filter screen group, and is then sent to the external storage tank through the water pipe 42 for subsequent use. This solves the problem that the area where the device is set up is prone to collapse and needs to be re-excavated when constructing in swampy areas due to the influence of wet soil. The drained swampy area is suitable for photovoltaic plant construction, improving work efficiency.

[0032] like Figure 3 As shown, in a preferred embodiment, the filter box 32 is further included, and the filter mesh assembly is disposed within the filter box 32. The front side wall of the filter box 3 has an opening, and the left and right side walls have sliding grooves 33. The filter box 32 is vertically continuous, and the side walls are provided with sliders 34 that match the sliding grooves 33. In this embodiment, the filter mesh assembly is disposed within the filter box 32. During operation, the filter box 32 slides into the filter box 3 via the sliders 34 on the sliding grooves 33. After use, the filter box 32 can be removed to replace and clean the filter mesh assembly.

[0033] like Figure 3 As shown, in a preferred embodiment, the filter box 32 is provided with a handle 35 on its side wall. In this embodiment, the operator can more easily move the filter box 32 using the handle 35.

[0034] like Figure 3 As shown in the preferred embodiment, the filter assembly consists of an activated carbon adsorption layer 36, a HEPA filter 37, and a filter 38 from bottom to top. In this embodiment, the filter assembly is composed of different filter layers, which, when combined, increase the filtration efficiency.

[0035] like Figure 4 As shown, in a preferred embodiment, the outer wall of the baffle 212 is provided with a fixing cone 214, which is inserted into the side wall of the concave region for fixation. In this embodiment, after the fixing cone 214 is provided on the outer wall of the baffle 212, the stability of the device is increased by fixing it by inserting the fixing cone 214 into the side wall of the concave region.

[0036] like Figure 4As shown, in a preferred embodiment, a connecting seat 5 is also included; a second connecting plate 215 is provided on the side wall of the baffle 212, and the top of the telescopic rod 213 is hinged to the connecting seat 5, with the connecting seat 5 connected to the second connecting plate 215. In this embodiment, the addition of the connecting seat 5, which connects the baffle 212 and the telescopic rod 213 through the second connecting plate 215 and the connecting seat 5, improves stability and allows for direct replacement of small parts when components are damaged, avoiding the need for complete replacement.

[0037] like Figure 4 and Figure 5 As shown, in a preferred embodiment, the second connecting plate 215 is provided with a connecting hole, and a connecting rod 51 is inserted into the baffle 212 after passing through the connecting hole for fixation. In this embodiment, using the connecting rod 51 to fix the second connecting plate 215 and the baffle 212 improves stability.

[0038] like Figure 4 As shown, in a preferred embodiment, there are two connecting holes, symmetrically arranged on the left and right sides of the baffle 212. In this embodiment, there are two connecting holes, and correspondingly two connecting rods 51, providing fixing force from both the left and right directions.

[0039] like Figure 4 and Figure 5 As shown in the preferred embodiment, the side wall of the second connecting plate 215 is provided with a hollow connecting cylinder 52, the right end of the connecting rod 51 is provided with a connecting block 53, and the left end of the connecting rod 51 passes through the connecting cylinder 52 and is inserted into the second connecting plate 215. A spring 54 is sleeved on the outer wall of the connecting rod 51 inside the connecting cylinder 52. In this embodiment, when connecting the device, the connecting block 53 is first pulled to the right to move it away from the second connecting plate 215. Since the two ends of the spring 54 are fixedly connected to the right side wall of the second connecting plate 215 and the connecting cylinder 52 respectively, during the pulling process, the connecting cylinder 52 moves away from the second connecting plate 215, and the spring 54 is stretched. After the positions of the second connecting plate 215 and the baffle 212 are set, the connecting block 53 is released. At this time, the spring 54 restores its deformation and drives the connecting rod 51 to move and insert into the connecting hole, thus providing better support for the baffle 212.
