Technical Field

[0001] The utility model belongs to the technical field of cable trays, and particularly relates to a cable tray for water conservancy projects. Background Technique

[0002] As is well known, water conservancy projects mainly study the basic knowledge and skills in aspects such as engineering hydrology, water conservancy engineering survey, hydraulic reinforced concrete, hydraulic structures, engineering drawing, etc. Cable trays are required for laying cables during the construction of water conservancy project buildings.

[0003] In practical applications, common cable trays are all a single space for storing multiple cables pulled from different areas. During cable laying, due to factors such as an increase in the laying distance or various turns, the multiple cables are prone to getting chaotic. When there is a power outage or other influencing factors in a certain area and the cables need to be repaired or replaced, it is not convenient to quickly find the cables in that area for repair, and the practicability is poor. Therefore, developing a cable tray with high practicability, fast and convenient operation, and improved project efficiency has become a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Utility Model

[0020] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] Such as Figures 1-5As shown in the figure, the utility model discloses a cable tray for water conservancy projects, which comprises a U-shaped structure composed of a horizontal bottom plate 1 and two vertical support plates 2 on both sides of its top; several chutes 3 perpendicular to the support plates are evenly arranged on the surface of the bottom plate 1 between the two support plates 2; several convex sliding blocks 4 for adjusting positions are arranged in each chute 3, and the sliding blocks 4 are slidably matched with the chutes 3. After the sliding blocks 4 move in place, the sliding blocks 4 are fixedly connected with the chutes through fastening bolts 5.

[0022] On the bottom plate 1 on both sides of any chute, a plurality of vertical second through holes 9 are arranged for passing through cable ties to fix the cables laid on the bottom plate 1 through the cable ties.

[0023] On the side of the support plate 2 far away from the bottom plate 1, several fixing plates 10 are vertically arranged, and the cable tray is fixed at the required construction position through the fixing plates 10.

[0024] Preferably, mounting holes 11 are arranged on the fixing plates 10, and the cable tray is connected to a suspension rod or other devices through the mounting holes 11.

[0025] The chute 3 is a trapezoidal groove structure, which is matched with the convex sliding block 4, and the sliding block 4 slides along the chute 3; the width of the lower space of the chute 3 is greater than the width of the upper space to prevent the sliding block 4 from sliding out of the chute 3.

[0026] Preferably, the length direction of the chute 3 is perpendicular to the plane where the support plate 2 is located.

[0027] A threaded hole is penetrated through the sliding block 4, and the sliding block 4 is threadedly connected with the fastening bolt 5 through the threaded hole. The lower end face of the fastening bolt 5 contacts the bottom end face of the chute 3; after the position of the sliding block 4 in the chute 3 is adjusted, the fastening bolt 5 is tightened. At this time, the lower end of the fastening bolt 5 abuts against the bottom of the chute 3, and the sliding block 4 is fixed at this position in the chute 3.

[0028] Preferably, intervals are arranged between the sliding blocks 4 for the installation of cables.

[0029] On each sliding block 4, a partition plate 6 parallel to the support plate 2 is arranged; a rolling ball 7 is arranged at the lower end of the partition plate 6, and the partition plate 6 is rollingly connected with the bottom plate 1 through the rolling ball 7.

[0030] The middle part of the lower end of the partition plate 6 is fixedly connected with the top end of the sliding block 4, and when the sliding block 4 in the chute 3 moves, the partition plate 6 moves accordingly.

[0031] Preferably, several rolling grooves are provided at the lower end of the partition plate 6. Rolling balls 7 are rotatably connected in the rolling grooves. The lower ends of the rolling balls 7 are in contact with the upper surface of the bottom plate 1. The rolling balls 7 roll on the bottom plate 1, facilitating the movement of the partition plate 6. When the sliding block 4 slides in the sliding groove 3, it drives the partition plate 6 to move on the bottom plate 1. Multiple partition plates 6 divide the bottom plate 1 into different spaces for placing cables powered by different regions.

[0032] Preferably, several first through holes 8 are evenly provided on the partition plate 6. The first through holes 8 are used for passing through cable ties to bundle the separated cables.

[0033] A gap is provided between the partition plate 6 and the corresponding fastening bolt 5, facilitating the staff to rotate the fastening bolt 5 for adjustment.

[0034] Working principle:

[0035] When the cable tray is in use, the staff loosens the fastening bolt 5 on the sliding block 4 according to the number of cables in different regions, and then adjusts the position of the sliding block 4 in the sliding groove 3. The sliding block 4 drives the partition plate 6 to divide the bottom plate 1 into different large spaces, and then tightens the fastening bolt 5. At this time, the lower end of the fastening bolt 5 abuts against the bottom of the sliding groove 3, firmly fixing the partition plate 6 in the required position. Then, cables in different power supply regions are laid in the corresponding spaces, and cable ties are passed through the first through holes 8 and the second through holes 9 respectively to bundle and fix the cables.

[0036] When the cables need to be repaired or replaced, the cables in the required region can be quickly found and repaired. Therefore, the cable tray of the present invention has strong practicability.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
