In addition, when the device is placed, it only needs to manually drive the three legs 4 and place the monitor in the installation part 1 to monitor the target object. The operation is simple and the time consumed for installing the remote sensing monitoring equipment on the support structure is short, which effectively solves the technical problems existing in the prior art. Finally, since the sliding part 3 can reciprocate on the support rod 2 so that the height between the installation part 1 and the bearing surface can be adjusted, this structural design can increase the range that the monitor can monitor, and can adjust the height of the monitor according to actual needs to collect the required target objects, effectively improving the monitoring effect of the monitor when monitoring the target object.

The protective plate 13 can be a flat plate structure or a truncated cone-shaped plate structure, as long as it has a certain rigidity. In the present application, the shape of the protective plate 13 is preferably a truncated cone. This shape can not only protect the monitor, but also prevent rain or snow from accumulating on the protective plate 13 when encountering bad weather (such as rainy or snowy days), thereby effectively reducing the damage of rain or snow to the monitor.

[0054] like Figure 1 and Figure 4 As shown, in a specific implementation, one end of each connecting rod 12 facing away from the bottom plate 11 is connected to a moving rod 14, each moving rod 14 can be extended out or hidden in one end of the corresponding connecting rod 12, and one end of the moving rod 14 facing away from the connecting rod 12 is connected to the protective plate 13; wherein, an elastic element 15 is sleeved on the corresponding moving rod 14 exposed outside the connecting rod 12.

[0055] Specifically, the present application provides an embodiment of a connecting rod 12, that is, each connecting rod 12 includes: a cylinder having a connecting port at one end, the cylinder is a hollow cavity, the connecting port is connected to the cavity in the cylinder, a spring is arranged on the bottom surface of the cylinder away from the connecting port, the connecting port is covered with a cover plate, the cover plate and the cylinder are connected in a detachable manner, for example, bolt connection or threaded connection, the bottom surface of the cylinder away from the connecting port is connected to the bottom plate 11, and the connection method can be detachable or fixed, for example : Welding or bolt connection, a through hole is set through the cover plate so that the moving rod 14 passes through the through hole and is connected to the spring, and the corresponding moving rod 14 exposed outside the connecting rod 12 is connected to the protective plate 13. The connection method can be a detachable connection or a fixed connection method, for example: welding or bolt connection, one end of the elastic element 15 is connected to the cover plate, and the other end of the elastic element 15 is connected to the protective plate 13.

The elastic element 15 is a spring, which can be purchased. The elastic element 15 can be connected to the cover plate in a detachable manner or in a fixed connection manner, such as welding or bolting. The elastic element 15 can be connected to the protective plate 13 in a detachable manner or in a fixed connection manner, such as welding or bolting.

[0057] like Figure 1 and Figure 2 As shown, in a specific implementation, the sliding portion 3 is an annular sliding sleeve, and the inner wall of the sliding sleeve fits with the outer wall of the support rod 2 so that the sliding sleeve can reciprocate on the support rod 2 along the extension direction of the support rod 2.

[0059] like Figure 1 and Figure 2 As shown, in a specific implementation, a threaded hole is provided on the sliding sleeve, and a positioning bolt 5 is threadedly connected to the threaded hole. The positioning bolt 5 abuts against the outer wall of the support rod 2 through the threaded hole to stabilize the sliding sleeve at the target position on the support rod 2.

[0060] Specifically, this structural design can facilitate the relative stillness between the sliding sleeve and the support rod 2. When the technician needs to adjust the distance between the monitor and the bearing surface, the technician manually drives the sliding sleeve to make the sliding sleeve approach or move away from the bearing surface, so as to achieve the technician's adjustment effect on the distance between the monitor and the bearing surface. After the adjustment is completed, the technician rotates the positioning bolt 5 so that the bolt passes through the threaded hole and abuts against the outer wall of the support rod 2, thereby achieving the relative stillness between the sliding sleeve and the support rod 2, thereby achieving the effect of fixing the sliding sleeve.

[0061] like Figure 1 and Figure 3 As shown, in a specific implementation, each leg 4 can be extended or contracted.

[0062] Specifically, when the device is placed on an uneven ground, the length of each leg 4 is adjusted, i.e. stretched or contracted, so that the three legs 4 cooperate with the support rod 2 to stably support the mounting part 1 on the ground, so as to facilitate the monitor to monitor the target environment.

[0066] like Figure 1 and Figure 3 As shown, in a specific implementation, each outer rod 41 has a slide groove 43 on its two opposite side walls, the extension direction of each slide groove 43 is the same as the extension direction of the corresponding outer rod 41, each slide groove 43 is connected to the inside of the corresponding outer rod 41, and each outer rod 41 is equipped with a fixing bolt 44 and a fixing nut 45, one end of each fixing bolt 44 passes through a slide groove 43 of the corresponding outer rod 41, one end of the corresponding inner rod 42 and another slide groove 43 of the corresponding outer rod 41 in sequence, and is threadedly connected with the corresponding fixing nut 45; wherein the other end of each fixing bolt 44 cooperates with the corresponding fixing nut 45 to clamp the side wall of the corresponding outer rod 41, so that the corresponding inner rod 42 moves to the target position of the corresponding outer rod 41 and is fixed.

[0067] Specifically, after each leg 4 completes the movement of approaching (contracting) or moving away (stretching) from each other through the corresponding inner rod 42 and outer rod 41, in order to ensure that the inner rod 42 and the outer rod 41 can remain relatively still, the technician can fix the outer rod 41 and the inner rod 42 by fixing the bolts 44 and the nuts 45 to maintain the positional relationship between the inner rod 42 and the outer rod 41 after the relative movement.

[0068] The slide groove 43 is provided to cooperate with the fixing bolt 44 and the fixing nut 45 to fix the stretched or contracted leg 4, and secondly, to play a guiding role to assist the inner rod 42 to slide in the corresponding outer rod 41.

[0070] Specifically, the other end of each inner rod 42 is hinged with a fixing plate 6, which is used to assist the corresponding leg 4 in supporting. The fixing plate 6 is a straight plate structure with fixing holes. Technicians can use the fixing holes to cooperate with other devices, such as rivets or bolts, which can be embedded in the ground, to make the inner rod 42 cooperate with the fixing holes on the fixing plate 6 to be firmly fixed on the ground, so as to improve the stability of the device during installation.
