Description

Technical Field

[0001] The utility model relates to the technical field of road monitoring devices, in particular to a track safety monitoring and early warning device. Background Art

[0002] Railway safety is the cornerstone of safe railway operation, but rainfall poses a double threat to railways: limited vision requires train crews to drive carefully; frequent geological disasters put the foundation of the railway tracks at risk. Therefore, the railway department must monitor rainfall, temperature and geology in advance.

[0003] At present, railway track monitoring and early warning devices are usually used for railway track detection. For example, the railway track monitoring and early warning device disclosed by patent announcement number CN215575727U includes a mounting frame, a meteorological monitoring device, a photovoltaic system, a background server and a remote terminal. The camera, vibration sensor and wind direction sensor on the mounting frame are used to detect the weather, geology, temperature, wind volume, etc. ahead.

[0004] However, the existing technology is similar to the above-mentioned railway track monitoring and early warning device, and still has some defects: the height of this type of monitoring and early warning device is fixed, and its detection height cannot be adjusted for different terrains, and it is impossible to adjust different installation heights for different terrains. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a rail safety monitoring and early warning device, which is not only suitable for setting up monitors such as cameras at different heights in different terrains, but also eliminates the problem of upper tube rotation and incorrect monitoring angle of the monitor caused by direct threaded connection of the upper and lower tubes.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A track safety monitoring and early warning device comprises a base and a support rod, wherein the support rod is formed by an upper tube portion being sleeved on the outer side of a lower tube, an outer side of the middle portion of the lower tube is provided with an external thread, a support ring is threadedly connected to the external thread, and the bottom end of the upper tube is overlapped on the support ring.

[0008] By adopting the above technical solution, on the one hand, the support rod is set up as two parts, the upper and lower parts, so that the two parts can move relative to each other, thereby adjusting the height of the entire support rod, so as to be suitable for setting monitors such as cameras at different heights in different terrains. On the other hand, by setting the support ring, the problem of upper tube rotation and incorrect monitoring angle of the monitor caused by direct threaded connection between the upper and lower tubes is avoided.

[0009] The utility model is further configured that a handle is provided at the bottom of the outer wall of the upper tube.

[0010] By adopting the above technical solution, the handle facilitates the lifting of the upper tube. The staff can hold the upper tube with one hand and rotate the support ring with the other hand, without the need for multiple people to operate.

[0011] The utility model is further configured that a plurality of pulleys are provided on the top of the outer wall of the lower tube, and the pulleys are movably connected to the inner wall of the upper tube.

[0012] By adopting the above technical solution, the pulley reduces the friction between the upper and lower tubes, further facilitating the staff to lift the upper tube.

[0013] The utility model is further configured that the inner wall of the upper tube is provided with a track groove matched with the pulley along its length direction.

[0014] By adopting the above technical solution, the track groove has a guiding function, which can prevent the upper and lower tubes from rotating when the height is adjusted, thereby avoiding the problem of incorrect monitoring angle of the monitor.

[0015] The utility model is further configured that a limiting ring is fixed on the outer wall of the lower tube below the external thread.

[0016] By adopting the above technical solution, the limit ring can provide support at the lowest point, avoiding the risk of the support ring and the upper tube falling directly when the support ring is separated from the external thread.

[0017] The utility model is further configured such that the outer diameter of the limiting ring is smaller than the outer diameter of the supporting ring.

[0018] By adopting the above technical solution, it is convenient to lift the limiting ring that is in contact with the supporting ring.

[0019] The utility model is further configured that the outer wall of the support ring is provided with anti-slip grooves.

[0020] By adopting the above technical solution, the support ring can be easily rotated and the slipping problem can be reduced.

[0021] The utility model is further configured that the outer wall edge of the support ring is provided with a rounded corner.

[0022] By adopting the above technical solution, the rounded corner has no edges, which can avoid the problem of scratches when the supporting ring is rotated.

[0023] The utility model is further configured that a flexible pad is provided on the top surface of the support ring.

[0024] By adopting the above technical solution, the collision between the support ring and the upper tube is reduced, and the service life of both is increased.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. By dividing the support ring into upper and lower tubes and setting a support ring connected to the lower tube with threads, the upper and lower tubes can move relative to each other, thereby adjusting the height of the entire support rod, so that it is suitable for setting monitors such as cameras at different heights in different terrains. On the other hand, the setting of the support ring eliminates the problem of upper tube rotation and incorrect monitoring angle of the monitor caused by direct threaded connection of the upper and lower tubes.

[0027] 2. By setting handles, pulleys, and track grooves, it is not only convenient to lift and lower the upper and lower tubes, but also can prevent the upper and lower tubes from rotating when adjusting the height, thereby avoiding the problem of incorrect monitoring angles of the monitor.

[0028] 3. By setting a limit ring, the upper tube can be supported at the lowest point to avoid the risk of the support ring and the upper tube falling directly when the support ring is separated from the external thread. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0033] The following describes an embodiment of the utility model based on its overall structure.

[0034] A track safety monitoring and early warning device, such as Figure 1 and Figure 2 As shown, it includes a base 1 and a support rod 2, and a meteorological monitoring device (camera, rain sensor, wind speed sensor and temperature sensor), a photovoltaic system, and a waterproof chassis are installed on the support rod 2.

[0035] In some embodiments, the support rod 2 is formed by partially sleeved an upper tube 21 on the outer side of a lower tube 22, an outer side of the middle part of the lower tube 22 is provided with an external thread 3, a support ring 4 is threadedly connected to the external thread 3, and the bottom end of the upper tube 21 is overlapped on the support ring 4. By setting the support rod 2 into two parts, the two parts can move relative to each other, so as to adjust the height of the entire support rod 2, so as to be suitable for setting monitors such as cameras at different heights in different terrains. On the other hand, by setting the support ring 4, the problem of rotation of the upper tube 21 and incorrect monitoring angle of the monitor caused by the direct threaded connection of the upper and lower tubes 22 is eliminated. In order to facilitate the operation of the support ring 4, in some embodiments, the outer wall of the support ring 4 is provided with anti-slip grooves, and the outer wall edge of the support ring 4 is provided with rounded corners.

[0036] In order to reduce the rigid collision between the support ring 4 and the upper tube 21, in some embodiments, a flexible pad 9 is provided on the top surface of the support ring 4. The flexible pad 9 can be a rubber pad, a silicone pad, foam, etc.

[0037] Since the upper tube 21 and the device thereon have a certain weight and are not convenient to lift, in some embodiments, a handle 5 can be provided at the bottom of the outer wall of the upper tube 21, and a plurality of pulleys 6 can be provided individually or simultaneously at the top of the outer wall of the lower tube 22, so that the pulley 6 is movably connected to the inner wall of the upper tube 21. In a preferred embodiment, the inner wall of the upper tube 21 is also provided with a track groove 7 cooperating with the pulley 6 along its length direction, which not only facilitates the lifting and lowering between the upper and lower tubes 22, but also prevents the upper and lower tubes 22 from rotating when the height is adjusted, thereby avoiding the problem of incorrect monitoring angle of the monitor.

[0038] In order to avoid the problem of the support ring 4 slipping out of the hand when it is separated from the external thread 3, in some embodiments, a limiting ring 8 is fixed to the outer wall of the lower tube 22 below the external thread 3, and the outer diameter of the limiting ring 8 is preferably smaller than the outer diameter of the support ring 4. The support ring 4 will fall on the limiting ring 8 after being separated from the external thread 3, and the larger outer diameter of the limiting ring 8 makes it easier for the staff to lift the limiting ring 8 that is in contact with the support ring 4.

[0039] In summary, the utility model mainly has the following beneficial effects: when installing the early warning device, first align the camera and the sensor towards the specified position, then install the base 1 on the ground, and then lift the upper tube 21 with one hand and rotate the support ring 4 with the other hand to achieve the height adjustment of the early warning device. It is not only suitable for setting monitors such as cameras at different heights in different terrains, but also eliminates the problem of rotation of the upper tube 21 and incorrect monitoring angle of the monitor due to the direct threaded connection of the upper and lower tubes 22.
