DETAILED DESCRIPTION

[0021] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 5 The utility model provides an embodiment: a remote early warning device, including a base 1 for assembling and supporting a camera body 3, which can be assembled by casting or other methods. A column 2 is vertically arranged on the top of the base 1, and the column 2 is assembled with the camera body 3 through a sliding mechanism and a connecting component. The camera body 3 is used to monitor and warn the scene, and has a built-in intercom function (mainly composed of audio acquisition, decoding and output modules, etc., which is a relatively mature technology and will not be described here). When an abnormality is found, the microphone of the monitoring device can be viewed through a computer or the like to make an alarm operation. The camera body 3 can be equipped with a PLC and a wireless transmission device (which can be transmitted through a local area network, etc.), and remote viewing and monitoring can be performed through a computer, which is a relatively mature technology and will not be described here.

[0023] See also Figure 1-Figure 5In order to facilitate the assembly and use of the camera body 3, and to facilitate the subsequent maintenance without the need for climbing operations, a guide groove 12 of a sliding mechanism is provided inside the column 2 (the cross-sectional shape can be T-shaped or other shapes, which is convenient for sliding and limiting at the same time), and a guide block 7 is slidably matched inside it. In order to reduce the friction during sliding, balls 11 are rolled on the two side walls of the guide block 7, and a guide rail 13 is provided in the guide groove 12 to facilitate the rolling of the balls 11. The guide block 7 is located outside the guide groove 12 and a connecting plate 8 with a connecting component can be fixed by screws, and the connecting plate 8 is assembled with the camera body 3 through a mounting seat 9. At the same time, in order to facilitate the lifting operation, remote monitoring and early warning, and subsequent maintenance operations, two sets of vertical plates 18 of the adjustment mechanism are symmetrically welded on the top plate 4, and a guide wheel 19 is rotatably provided between the two vertical plates 18, and a placement cavity 21 is provided inside the base 1, and a guide wheel 19 is also provided inside it through a rotating shaft 22, and a connecting rope 10 (such as Figure 4 As shown), the two ends of the connecting rope 10 can be fixedly connected to the top and bottom ends of the guide block 7 through the connecting ring, so that the guide block 7 can be conveniently moved up and down in the guide groove 12 for easy adjustment. In order not to affect the influence of the cable when the camera body 3 is lifted or lowered, a rope reel 20 (a relatively mature technology, which will not be described here) is provided on the outside of the rotating shaft 22. The cable is wound on the outside and can be rotated together during lifting and lowering, and can be retracted and released accordingly, without affecting normal use and avoiding entanglement.

[0024] See also Figure 1-Figure 5 In order to ensure stability during use and after maintenance and lowering to avoid sliding, a positioning column 5 of the plug-in assembly is welded to the middle of the top of the connecting plate 8, and a positioning hole 6 for plugging with the positioning column 5 is opened on the top plate 4, which can assist in plugging and positioning when it is raised for use. At the same time, a rectangular block 14 is welded on the side wall (rear end) of the column 2, and its height is about 1.2-1.6m, which is convenient for the staff to adjust the operation. A through hole 16 that does not affect the passage of the connecting rope 10 is opened in the middle of the rectangular block 14, and fastening bolts 15 are threadedly engaged on both sides of the rectangular block 14, which penetrate the interior and are bonded with anti-skid pads 17. After the adjustment is completed, the two fastening bolts 15 can be rotated to make them close to each other, and the connecting rope 10 can be clamped and fixed with the anti-skid pad 17 to prevent sliding.

[0025] Working principle: When the utility model is in use, when the camera body 3 needs to be raised for use, the connecting rope 10 behind the column 2 is pulled downward, and in cooperation with the two guide wheels 19, the guide block 7 can be slid upward in the guide groove 12, and the ball 11 rolls in the guide rail 13 for easy upward movement. After moving to the top, the positioning column 5 is inserted into the positioning hole 6 to complete the initial plug-in positioning, and then the fastening bolt 15 is rotated clockwise to bring the two closer to each other, and then the anti-skid pad 17 can be cooperated to approach each other to clamp and fix the connecting rope 10 to avoid sliding, which does not affect normal monitoring use. When maintenance is needed, the fastening bolt 15 can be rotated counterclockwise to move the two anti-skid pads 17 away from each other. The clamping effect on the connecting rope 10 is lost, and the connecting rope 10 is pulled upward. In conjunction with the guide wheel 19, the guide block 7 can be moved downward in the guide groove 12, and then it can be lowered. After it is lowered to a height convenient for work, the connecting rope 10 can be positioned and fixed by tightening the fastening bolts 15 to avoid sliding during maintenance.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
