Description

Technical Field

[0001] This utility model relates to the field of building engineering, specifically to a temporary power cable tray structure for outdoor building construction sites. Background Technology

[0002] During outdoor construction, temporary cables are sometimes required for power supply. To ensure cable safety, cable trays are used for cable installation. Cable trays keep cables off the ground, reducing contact with external elements and thus protecting them, improving the safety of temporary power supply at outdoor construction sites. Since timely drainage is needed in construction pits, existing technologies combine cable trays with drainage ditches. For example, a stepped prefabricated drainage ditch structure (patent number CN214940299U) consists of multiple prefabricated drainage ditch blocks connected end-to-end. The prefabricated drainage ditch blocks have grooves for laying fire-fighting pipes, and prefabricated cable trench blocks are located on the outside of the drainage ditch blocks, with cable grooves inside for cable installation. In on-site use, fire-fighting pipes are placed directly inside the prefabricated drainage ditch blocks, and the cables are placed on top of the prefabricated cable trench blocks after filling them with gravel, forming a complete temporary power supply and drainage system. However, in the existing structure, the height of the precast cable trench blocks is basically the same as the height of the precast drainage ditch blocks. Construction wastewater and sewage containing a large amount of mud, sand, mortar, and other waste materials at the construction site will flow into the precast cable trench blocks, which can easily cause cable aging and is not conducive to the reuse of cables. Therefore, it is necessary to improve this structure. Summary of the Invention

[0003] The purpose of this utility model is to propose a temporary power cable tray structure for outdoor construction sites to solve the above-mentioned technical problems.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A temporary electrical cable tray structure for outdoor construction sites includes a drainage ditch and a cable tray trough. The cable tray trough is located above and in the middle of the drainage ditch. The drainage ditch is a long, narrow shell structure with a water inlet at the top and openings at both ends. The cable tray trough is a long, narrow shell structure with a cable tray opening at the top and openings at both ends. The cable tray trough has multiple support plates spaced apart along its length on its bottom surface. The top of each support plate is fixedly connected to the bottom surface of the cable tray trough, and the bottom end is located inside the drainage ditch. The support plate has a trapezoidal structure that is narrower at the top and wider at the bottom, and a drainage opening is located in the middle of the support plate.

[0006] In the optimized design, the two sides of the support plate are clamped between the inner walls of the two sides of the drainage ditch, thereby ensuring a secure connection between the cable tray ditch and the drainage ditch via the support plate. Furthermore, each side of the support plate has a vertically arranged arc-shaped elastic portion.

[0007] In the optimized design, the support plate has two symmetrically arranged triangular plates, spaced apart to form a drainage opening. Further, the triangular plates are right-angled triangles, with their hypotenuses arranged away from each other to form a single support plate. Still further, the tops of the two triangular plates are fixedly connected by a connecting plate.

[0008] In the optimized design, the top two sides of the drainage trough have upwardly arranged water guide plates.

[0009] In the optimized design, the top of the cable tray trough is further provided with a top cover, which covers the cable tray opening of the cable tray trough. Furthermore, the top cover has a conical shell-like structure with a higher center and lower sides.

[0010] The optimized solution is that the bottom surface of the cable tray has multiple wiring channels arranged at intervals along the length direction.

[0011] This utility model has the following substantial features and advancements:

[0012] 1. The cable tray trough of this utility model is always higher than the drainage trough, so construction wastewater and sewage at the construction site will not flow into the cable tray trough, which is very beneficial to the long-term reuse of cables; in addition, this utility model also has the characteristics of simple structure, easy-to-obtain materials, and low production cost.

[0013] 2. This utility model uses a support plate with a trapezoidal structure that is narrower at the top and wider at the bottom, so that the cable tray is stably supported above the drainage trough 1; and furthermore, the support plate is detachably installed in the drainage trough by plugging it in, which realizes quick and stable installation, can significantly reduce the workload, and is also conducive to subsequent disassembly and reuse.

[0014] 3. During on-site construction, this utility model enables the rapid assembly of multiple cable tray structures, allowing cables to be installed within the tray grooves. When drainage is required during outdoor construction, drainage is achieved through the installed drainage channels. It features a simple structure, ease of implementation, and convenient use, achieving the dual functions of on-site drainage and cable installation. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Example 1

[0022] refer to Figures 1 to 3 A temporary power cable tray structure for outdoor construction sites includes a drainage trough 1 and a cable tray trough 2. The cable tray trough 2 is arranged in the upper middle part of the drainage trough 1. The drainage trough 1 is a long strip shell structure with a water inlet at the top and openings at both ends. The cable tray trough 2 is a long strip shell structure with a cable tray opening at the top and openings at both ends.

[0023] The bottom surface of the cable tray trough 2 has multiple support plates 3 arranged at intervals along its length. The top of each support plate 3 is fixedly connected to the bottom surface of the cable tray trough 2, and the bottom is located inside the drainage trough 1. The support plate 3 has a trapezoidal structure that is narrower at the top and wider at the bottom, and a drainage opening 30 is located in the middle of the support plate 3. The drainage opening 30 serves to ensure that the drainage channel in the drainage trough 1 is not blocked by the support plate 3 and remains unobstructed.

[0024] In this embodiment, the drainage trough 1, cable tray trough 2, and support plate 3 are all made of metal sheet. During on-site construction, after digging trenches on the ground, multiple drainage troughs 1 are sequentially buried along the trenches to form a continuous drainage channel, with the top of the drainage trough 1 flush with the ground. Specifically... Figure 3 Then, multiple cable tray troughs 2 are laid out above the drainage ditch 1 to form a continuous cable tray channel. The cable tray troughs 2 are supported by a support plate 3 at their bottom, positioned above the center of the drainage ditch 1, thus leaving a gap between the cable tray troughs 2 and the drainage ditch 1. Meanwhile, because the support plate 3 adopts a trapezoidal structure that is narrower at the top and wider at the bottom, it can provide good positioning and support for the cable tray troughs 2. Of course, the bottom end of the support plate 3 can also be welded to the drainage ditch 1 to make the cable tray troughs 2 more stable. Furthermore, the aforementioned gap serves the following purposes: 1. Rainwater on the ground can flow into the drainage ditch 1 through the gap to solve the problem of ground water accumulation; 2. If drainage problems occur in the drainage ditch 1, excess water will overflow to the ground through the gap instead of overflowing into the cable tray troughs 2; 3. It also facilitates the timely detection of water accumulation by staff, allowing for quick dredging of the drainage ditch 1 and rapid resolution of water accumulation problems.

[0025] Furthermore, the support plate 3 has two symmetrically arranged triangular plate portions 32, spaced apart to form a drainage opening 30 for the support plate 3. Also, the triangular plate portions 32 are right-angled triangles, with their hypotenuses arranged far apart to form one support plate 3. The use of triangular plate structures is advantageous because materials are readily available, the structure is simple, and the manufacturing cost is low.

[0026] Furthermore, the tops of the two triangular plate portions 32 of the support plate 3 are fixedly connected by a connecting plate portion 33, thereby increasing the stability of the support plate 3 and avoiding obstruction of the drainage channel in the drainage trough 1.

[0027] Furthermore, the top two sides of the drainage trough 1 have upwardly arranged water guide plates 11, which facilitate the flow of water accumulated on the ground into the drainage trough 1 and then quickly discharged along the drainage trough 1.

[0028] Furthermore, the top of the cable tray trough 2 is also provided with a top cover 4, which covers the cable tray opening of the cable tray trough 2. The top cover 4 further prevents rainwater from entering the cable tray trough 2. In addition, the cross-section of the top cover 4 is a conical shell structure with a high center and low sides, which facilitates the rapid drainage of rainwater.

[0029] Furthermore, the bottom surface of the cable tray trough 2 has multiple wiring grooves 21 arranged at intervals along its length. The wiring grooves 21 allow for the orderly and systematic arrangement of cables, which facilitates subsequent maintenance and management.

[0030] Example 2

[0031] refer to Figure 4 and Figure 5 The difference between the temporary power cable tray structure for outdoor construction sites in this embodiment and that in embodiment 1 is that the two sides of the support plate 3 are clamped between the inner walls of the two sides of the drainage trough 1, thereby making the cable tray trough 2 securely connected to the drainage trough 1 through the support plate 3. During installation, the support plate 3 on the cable tray trough 2 is inserted into the pre-buried drainage trough 1 from top to bottom. In particular, the support plate 3 has a structure that is narrow at the top and wide at the bottom, so the contact area between the support plate 3 and the inner wall of the drainage trough 1 is small when inserted, ensuring that the insertion operation is very easy and quick. This not only securely erects the cable tray trough 2 above the drainage trough 1, but also avoids the welding operation described in embodiment 1, which can significantly reduce the workload and facilitate subsequent disassembly and reuse.

[0032] Furthermore, the support plate 3 has vertically arranged arc-shaped elastic portions 31 on both sides. The arc-shaped elastic portions 31 give the two sides of the support plate 3 a certain degree of stretching elasticity, which is more conducive to the convenience and tightness of the connection between the support plate 3 and the drainage groove 1.
