[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example:

[0038] like Figures 1-5 As shown, this utility model provides a technical solution: a safety monitoring device for cable tunnels, comprising:

[0039] Fixed shell 1;

[0040] Transmission assembly 2 is placed inside the fixed housing 1. Transmission assembly 2 includes a transmission frame 21 that is slidably connected inside the fixed housing 1. A transmission rod 22 is slidably connected to the transmission frame 21. A first rotating shaft 23 is fixedly connected to the transmission rod 22. A monitoring device body 24 is rotatably connected to the first rotating shaft 23. A second rotating shaft 25 is slidably connected to the bottom of the monitoring device body 24. A fixing block 26 is fixedly connected to the second rotating shaft 25. A first motor 28 is fixedly connected to the bottom of the fixing block 26.

[0041] Fixed frame 3 is slidably connected to transmission frame 21 and fixedly connected to fourth fixed rod 31;

[0042] Sliding block 4 is fixedly connected to the bottom of the first motor 28. A third fixed rod 41 is slidably connected to the sliding block 4. A threaded rod 44 is fixedly connected to the third fixed rod 41. The threaded rod 44 is threadedly connected to the transmission frame 21. A second motor 42 is fixedly connected to the bottom of the third fixed rod 41. A fixed plate 5 is fixedly connected to the bottom of the second motor 42. A round block 11 is fixedly connected to the bottom of the fixed plate 5.

[0043] In this invention, a second motor 42 drives a third fixed rod 41, causing the transmission frame 21 to move up and down. This causes the transmission rod 22 to slide within the transmission frame 21, rotating the first rotating shaft 23 and allowing the monitoring device body 24 to flip. Simultaneously, a first motor 28 drives a fixed block 26 to rotate, causing the second fixed rod 27 to slide within the monitoring device body 24. Combined with the limiting effect of the transmission rod 22, this further shifts the monitoring device body 24. This composite adjustment method greatly expands the monitoring angle range, enabling multi-dimensional angle adjustment of the monitoring device body 24. It effectively solves the problem of blind spots caused by limited angle adjustment in complex cable tunnel structures (such as bends) of existing monitoring devices, providing more comprehensive coverage of all areas of the tunnel.

[0044] The fixed plate 5 is provided with a groove, and the second motor 42 is fixedly connected in the groove on the fixed plate 5. The groove is specially designed on the fixed plate 5 to provide a suitable space for the installation of the second motor 42. The size of the groove is closely matched with the contour of the second motor 42. In use, the operator can conveniently and quickly embed the second motor 42 in the groove without complex positioning operation. Not only the installation time is saved, but also the second motor 42 is closely combined with the fixed plate 5 to become a stable whole, thereby providing a reliable power basis for the stable operation of the whole device.

[0045] The transmission frame 21 is provided with a limiting groove, and the limiting rod 6 is slidably connected in the limiting groove on the transmission frame 21. The limiting rod 6 is fixedly connected with the transmission rod 22. The limiting groove has a suitable width and depth, and the limiting rod 6 is closely embedded therein and can smoothly slide. When the device operates and the transmission rod 22 is linked with each component, the limiting rod 6 stably slides in the limiting groove to strictly limit the transmission rod 22 from two dimensions of horizontal and vertical directions, effectively prevents the transmission rod 22 from deviating from the predetermined track due to uneven force, vibration and other factors, ensures the execution of the transmission action, and avoids interference with the angle adjustment of the monitoring device body 24.

[0046] The monitoring device body 24 is provided with a groove, and the second fixed rod 27 is fixedly connected on the fixed frame 3 and slidably connected in the groove in the monitoring device body 24. The inner wall of the groove is smooth and has high dimensional accuracy, and is well matched with the second fixed rod 27. In use, as the fixed block 26 is driven to rotate by the first motor 28, the second fixed rod 27 stably slides in the groove. This cooperation restricts the movement direction of the monitoring device body 24, so that it can only deviate and adjust according to the predetermined design path. On the other hand, it ensures that the monitoring device body 24 is stable in the process of complex angle conversion, without skewing, mispositioning and other conditions, and ensures accurate positioning of the monitoring angle.

[0047] The sliding block 4 is fixedly connected with the electric telescopic rod 43 at the bottom, and the electric telescopic rod 43 is fixedly connected to the fixed plate 5 at the bottom. Under normal working conditions, the electric telescopic rod 43 is in standby state and does not affect the cooperative work of other components. Once the second motor 42 on one side suddenly fails, the electric telescopic rod 43 immediately responds and quickly and stably drives the sliding block 4 to lift by virtue of its stable telescopic power. The telescopic stroke is accurately designed to meet the adjustment requirements of the device in emergency state, avoid being paralyzed due to motor failure, maintain the monitoring angle adjustment function, ensure uninterrupted tunnel monitoring, and support the monitoring device body 24.

[0048] The transmission rod 22 is in sliding connection with the fixed frame 3. When the device starts the adjustment program, the transmission rod 22 slides according to its own movement track, and the side surface thereof is in contact with the contact part of the fixed frame 3, which is designed to have a reasonable friction coefficient. Thus, the transmission rod 22 can smoothly push the fixed frame 3 to move, and the friction force is not too small to cause the pushing to be powerless or too large to hinder the movement. In this process, the fixed frame 3 is forced to drive the fourth fixed rod 31 and the monitoring device body 24 to move synchronously, and the components are closely linked to realize the rapid and accurate adjustment of the monitoring range and effectively cope with the monitoring requirements of different areas in the tunnel.

[0049] The transmission frame 21 is provided with an opening, and the bottom of the fixed frame 3 is in sliding connection with a cylindrical block. The cylindrical block at the bottom of the fixed frame 3 is in sliding connection in the opening on the transmission frame 21, and the cylindrical block at the bottom of the fixed frame 3 is in sliding connection with the threaded rod 44 and the limiting rod 6. The shape and size of the opening are perfectly matched with the cylindrical block. The cylindrical block can flexibly slide in the opening and is constrained by the boundary of the opening to ensure the stability of the fixed frame 3 when moving up and down. At the same time, the sliding connection of the cylindrical block with the threaded rod 44 and the limiting rod 6 enables the fixed frame 3 to move up and down along the opening by the contact with the cylindrical block when the threaded rod 44 rotates. The limiting rod 6 further assists in calibration, so that the fourth fixed rod 31 drives the monitoring device body 24 to stably and accurately lift, and optimizes the vertical coverage effect of the monitoring area to adapt to the monitoring task of different height positions in the cable tunnel.

[0050] Working principle: as shown in Figures 1-5 When used, the circular block 11 is fixed in the installation position in the tunnel by means of bolts.

[0051] Then, when it is necessary to adjust the monitoring position of the monitoring device body 24, the second motor 42 is started at the same time to drive the third fixed rod 41 to move the transmission frame 21 up and down, drive the transmission rod 22 to slide in the transmission frame 21, and drive the first rotating shaft 23 to rotate. At this time, the monitoring device body 24 is turned over under the action of the first rotating shaft 23.

[0052] The first motor 28 is started to drive the fixed block 26 to rotate, drive the second fixed rod 27 to slide in the monitoring device body 24, drive the fixed frame 3 to slide, contact the transmission rod 22, and deviate under the limiting action of the transmission rod 22. Thus, the second fixed rod 27 is further driven to slide at the bottom of the monitoring device body 24, drive the monitoring device body 24 to deviate, and realize further adjustment.

[0053] The above merely describes preferred embodiments of the present application and is not intended to limit the present application in any form, although the present application has been disclosed as above with preferred embodiments, however, it is not intended to limit the present application, any person skilled in the art without departing from the technical scheme of the present application can make some changes or modifications to the above-mentioned technical content for equivalent embodiments, the implementation schemes in the above-mentioned embodiments can be further combined or replaced, as long as it does not deviate from the technical scheme of the present application, any simple modification, equivalent change and modification made to the above-mentioned embodiments according to the technical essence of the present application still belongs to the scope of the present application.
