[0024] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0025] Example 1

[0026] like Figures 1-4 As shown, this embodiment provides a ventilated hydraulic cable trench cover device, which includes: a protective outer frame 100, and a cable trench cover 200 covering the protective outer frame 100; one end of the cable trench cover 200 is hinged to the protective outer frame 100; support portions 300 for supporting the cable trench cover 200 when it is in the open state are provided at the upper and lower ends of the inner surface of the protective outer frame 100.

[0027] In this embodiment, the protective frame 100 provides a stable boundary for the cable trench, effectively preventing external objects or personnel from accidentally entering the trench and causing potential damage to the cables. Simultaneously, the protective frame 100 also provides a supporting foundation for the cable trench cover 200, ensuring stable installation of the cover.

[0028] In this embodiment, the cable trench cover 200 covers the protective frame 100, protecting the cables from external environmental damage such as rain and dust. Meanwhile, the support 300 is designed for easy opening and closing, facilitating ventilation and sun drying in the cable trench.

[0029] In this embodiment, the support part 300 includes a first connector 310 with one end fixedly connected to the inner surface of the cable trench cover plate 200 near the protective outer frame 100, a second connector 320 with the other end fixedly connected to the inner surface of the protective outer frame 100 away from the protective outer frame 100, and a hydraulic support rod 330 with both ends movably connected to the first connector 310 and the second connector 320 respectively.

[0030] Through the reasonable position relationship between the first joint 310 and the second joint 320 in the embodiment, the hydraulic support rod 330 can be extended or retracted when needed, so as to realize the support or release of the cover plate. The hydraulic support rod 330 also enables the cover plate to be stable in the open state and not to sway due to external factors such as wind, thereby improving the safety.

[0031] In the embodiment, the inner surface of the cable trench cover plate 200 is provided with a support frame 210 for covering the inner surface of the protective outer frame 100 when the cable trench cover plate 200 is closed.

[0032] In the embodiment, the support frame 210 is arranged on the inner surface of the cable trench cover plate 200 and is used to cover the bottom of the mounting cavity when the cover plate is closed. The design of the support frame 210 can effectively disperse the pressure of the cover plate on the cable trench bottom and prevent the cable trench from being damaged due to excessive local pressure.

[0033] In the embodiment, the protective outer frame 100 includes an outer frame 110 and a protective plate 120 arranged in the outer frame 110, and the outer frame 110 and the protective plate 120 jointly constitute a mounting space 130 for closing the cable trench cover plate 200.

[0034] In the embodiment, the outer frame 110 constitutes the basic framework of the protective outer frame 100 and provides stable support for the protective plate 120.

[0035] In the embodiment, the protective plate 120 is provided with a ventilation hole 121.

[0036] In the embodiment, the ventilation hole 121 is arranged on the protective plate 120, so that the cable trench can exchange air with the outside, effectively reducing the humidity and temperature inside the cable trench, and preventing the cable from being damaged due to moisture or overheating.

[0037] In the embodiment, the side of the cable trench cover plate 200 close to the first joint 310 is connected to the inner wall of the side of the outer frame 110 close to the first joint 310 through a hinge 140.

[0038] In the embodiment, the side of the cable trench cover plate 200 close to the first joint 310 is connected to the inner wall of the side of the outer frame 110 close to the first joint 310 through a hinge 140, so that the cover plate can be easily and flexibly opened and closed, reducing the labor intensity of the operator, and the hinge 140 connection can also reduce the impact and noise of the cover plate during opening and closing to a certain extent.

[0039] In the embodiment, a handle slot 220 is formed on one side of the outer surface of the cable trench cover plate 200, and a handle 230 is rotatably installed in the handle slot 220.

[0040] By the handle groove 220 in this embodiment is opened in the outer surface side of the cable trench cover plate 200, the handle 230 is rotatably installed inside. The handle 230 is designed so that the operator can more conveniently open and close the cable trench cover plate 200, improving the convenience of operation.

[0041] The ventilation type hydraulic cable trench cover plate 200 device of the present embodiment is used when the cable trench cover plate 200 needs to be opened for ventilation and airing. The operator first applies an outward force to pull open the cable trench cover plate 200. At this time, the hydraulic support rod 330 begins to work, and its internal hydraulic system automatically responds to this external force. As the cover plate is gradually opened, the hydraulic support rod 330 gradually extends until it fully supports the cable trench cover plate 200. The hydraulic support rod 330 provides the necessary support force, allowing the cable trench cover plate 200 to hang smoothly and safely above the cable trench, avoiding sudden falling due to gravity. When the ventilation and airing or maintenance work is completed, the operator needs to close the cable trench cover plate 200. At this time, it only needs to gently push the cover plate to move it towards the protective outer frame 100. As the cover plate gradually approaches the protective outer frame 100, the hydraulic support rod 330 begins to automatically retract. Its internal hydraulic system automatically adjusts the size and direction of the support force according to the movement speed and position of the cable trench cover plate 200, ensuring that the cover plate can be closed smoothly and smoothly. When the cable trench cover plate 200 is completely closed on the protective outer frame 100, the hydraulic support rod 330 is completely retracted to the initial position and no longer exerts any support force on the cable trench cover plate 200.

[0042] It is easy to understand that those skilled in the art can combine, split, recombine, etc. the embodiments of the present application on the basis of one or several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.

[0043] In summary, the above only describes the preferred embodiments of the present application, and any changes and modifications made within the scope of the present application should be included in the scope of the present application.
