Detailed implementation manners

[0017] The present utility model will be further described in detail below in conjunction with the drawings and specific implementation manners. The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0018] Such as Figures 1-4An underground loop resistance on-line monitoring device shown in the figure includes a monitoring box. A display screen and a control panel are installed on the front side wall of the monitoring box. Slide rail components are installed at the edges on both sides of the monitoring box. The slide rail components extend at the edges of the top, front and bottom of the monitoring box. A protection component is connected between the slide rail components on both sides. The protection component slides along the slide rail components at the top, front and bottom of the monitoring box. Limit members for limiting the protection component are installed at the edges of the rear side of the top end and the rear side of the bottom end of the monitoring box;

[0019] Based on the above, the display screen and the control panel on the front side of the monitoring box are protected by the protection component, avoiding the occurrence of screen damage caused by foreign object impact during carrying, installation and use. And the protection component slides between the slide rail components on both sides. The whole protection component slides on the surface of the monitoring box, occupying little space and being convenient to use in a narrow working scene, improving portability.

[0020] Further, a magnetic strip is embedded at the top end of the monitoring box above the display screen. The magnetic strip cooperates with the protection component. When the protection component hangs in front of the display screen to protect the display screen, the magnetic strip is used for limiting and fixing.

[0021] The slide rail component includes an inner slide rail fixed at the edge of the monitoring box and an outer slide rail located outside the inner slide rail. A slideway is arranged between the inner slide rail and the outer slide rail. The two ends of the inner slide rail and the outer slide rail are respectively located at the top and bottom of the monitoring box, and the two ends of the inner slide rail and the outer slide rail are fixedly connected;

[0022] Baffles are fixedly installed on the outer side walls of the inner slide rail and the outer slide rail. The baffles extend along the directions of the inner slide rail and the outer slide rail. The baffles, the inner slide rail and the outer slide rail are integrally arranged;

[0023] A connecting plate is fixedly installed on the inner side wall of the inner slide rail. A number of bolts penetrate through the connecting plate. The connecting plate is fixedly installed on the outer wall of the monitoring box through the bolts. The thickness of the connecting plate is less than the thickness of the inner slide rail;

[0024] Based on the above, the inner slide rail of the slide rail component is installed and fixed on the outer wall of the monitoring box through the connecting plate. Therefore, the slide rail component can be disassembled on the monitoring box, and replacement and maintenance can be realized.

[0025] Further, it is set that the thickness of the connecting plate is less than that of the inner slide rail, so that the protection component will not be blocked by the connecting plate when sliding between the slide rail components.

[0026] The protection component includes a number of connecting rods. Both ends of the number of connecting rods are inserted into the slideways inside the slide rail components on both sides. Both ends of the connecting rods are in contact with the baffles in the slide rail components on both sides;

[0027] A pull rope runs through several connecting rods, and the pull rope connects and limits the positions of the several connecting rods in series. Magnet rings are fixedly installed on the outer walls of the two outermost connecting rods.

[0028] Based on the above, after several connecting rods are connected in series by the pull rope, they are limited between the inner slide rail and the outer slide rail of the two slide rail assemblies on both sides by the baffle. The end of the connecting rod fits against the baffle to prevent the connecting rod from falling off between the two slide rail assemblies on both sides. The user can pull the two outermost connecting rods to move the entire protection assembly along the slide way direction of the slide rail assembly, and move several connecting rods to the top, front or bottom of the monitoring box. When several connecting rods are located in front of the display screen, they provide a protection effect for the display screen. When several connecting rods are located at the top or bottom of the monitoring box, the display screen is exposed at this time for data display.

[0029] The limiting member includes a limiting rod, and the limiting rod is fixed on the outer wall of the monitoring box. When the protection assembly moves to the top of the monitoring box, the magnet ring can be sleeved outside the limiting rod, and a magnetic sheet matched with the magnet ring is installed at the bottom end of the limiting rod.

[0030] On the basis of the above, when several connecting rods are located in front of the display screen, the magnet rings on the connecting rods are adsorbed to the magnetic strip to hang several connecting rods in front of the display screen to provide a protection effect.

[0031] When it is necessary to move several connecting rods to the top or bottom of the monitoring box, the limiting rod is used to provide a limiting and blocking effect, and the magnetic sheet is used to adsorb the magnet ring to adsorb several connecting rods connected by the pull rope to the top or bottom of the monitoring box.

[0032] On the basis of the above, the present utility model can effectively protect the display screen part of the monitoring equipment in the narrow space environment underground, avoid screen damage caused by impact and collision during carrying, installation and use, and can be applied to complex underground line and pipeline structures, with small occupied space and strong adaptability.
