Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-4 As shown, this utility model provides a remote sensing measuring ruler, including a fixed plate 1. An electric telescopic rod 4 is fixedly installed at the bottom of the fixed plate 1. A base plate 5 is fixedly installed at the telescopic end of the electric telescopic rod 4.

A first threaded rod 8 is threadedly connected inside the threaded hole 7. A U-shaped seat 10 is movably connected to the bottom of the first threaded rod 8. A handle 9 is fixedly installed at the top of the first threaded rod 8. A limit plate 11 is fixedly installed at the top of the U-shaped seat 10. The top of the limiting plate 11 is slidably inserted into the connecting plate 6. A rotating shaft 12 is rotatably installed between the two sides inside the U-shaped seat 10. A rotating plate 13 is fixedly installed on the outer wall of the rotating shaft 12. A universal wheel 14 is provided on the top of the rotating plate 13. A stop bar 15 is fixedly installed on the bottom of the rotating plate 13. Two slots 16 are symmetrically opened on the outer wall of the rotating plate 13. A limiting groove 17 is opened on the inner wall of the U-shaped seat 10. A spring 18 is fixedly installed on the inner wall of the limiting groove 17. A locking block 19 is fixedly installed on one end of the spring 18. A pull plate 20 is fixedly installed on the outer wall of the locking block 19.

[0024] The effect achieved by the entire embodiment 1 is as follows: When in use, the operator places the device on the ground and keeps it horizontal. Then, the operator pulls the pull plate 20, which causes the locking block 19 to leave the slot 16 and the spring 18 to be compressed. Then, the operator rotates the rotating plate 13, which rotates 180 degrees, so that the abutment rod 15 faces downward. At this time, the pull plate 20 is released, and the elastic force of the spring 18 pushes the locking block 19 into another slot 16. Finally, the operator rotates the handle 9, and the first threaded rod 8 rotates, causing the first threaded rod 8 to descend along the threaded hole 7 until the abutment rod 15 contacts the ground. When all three abutment rods 15 are in contact with the ground, the device can be supported and prevented from tilting.

[0025] Example 2, as Figures 1-4 As shown, a protective cover 2 is fixedly installed on the top of the fixed plate 1. Two support plates 21 are fixedly installed on the top surface inside the protective cover 2. A second threaded rod 22 is rotatably installed between the two support plates 21. A first motor 24 is fixedly installed on the outer wall of one of the two support plates 21. The output end of the first motor 24 passes through the support plate 21 and is fixedly connected to the second threaded rod 22. A sliding plate 25 is threadedly connected to the outer wall of the second threaded rod 22.

[0026] Furthermore, a limiting rod 23 is fixedly installed between the two support plates 21, and the limiting rod 23 passes through the slide plate 25 and is slidably connected to the slide plate 25.

[0027] Furthermore, a movable plate 26 is fixedly installed on the outer wall of the slide plate 25, and a cylinder 27 is fixedly installed at the bottom of the movable plate 26. The output end of the cylinder 27 passes through the movable plate 26 and is fixedly installed with a lifting plate 28.

[0028] Furthermore, a second motor 29 is fixedly installed at the bottom of the lifting plate 28. The output end of the second motor 29 passes through the lifting plate 28 and is fixedly installed on a turntable 30. A measuring ruler body 31 is provided on the top of the turntable 30.

[0029] Furthermore, a level 3 is installed on the top of the protective cover 2 to facilitate staff to observe whether the device is level.

[0030] Furthermore, the outer wall of the card block 19 is in contact with the inner wall of the card slot 16 and the inner wall of the limiting groove 17 respectively. The contact between the outer wall of the card block 19 and the inner wall of the card slot 16 can ensure that the rotating plate 13 will not shake after the card block 19 enters the card slot 16. The contact between the outer wall of the card block 19 and the inner wall of the limiting groove 17 can prevent the card block 19 from tilting.

[0031] The effect achieved by the entire embodiment 2 is as follows: when in use, the operator starts the first motor 24, the second threaded rod 22 rotates, the slide plate 25 moves along the limit rod 23, the measuring ruler body 31 leaves the protective cover 2, then the operator starts the cylinder 27, the output end of the cylinder 27 pushes the lifting plate 28 up until the measuring ruler body 31 moves above the protective cover 2, and finally, the operator can start the second motor 29, the turntable 30 rotates with the measuring ruler body 31, thereby increasing the measuring range of the measuring ruler body 31.

[0032] Working principle: When in use, the operator places the device on the ground and keeps it level. Then, the operator pulls the pull plate 20, which causes the locking block 19 to leave the slot 16, compressing the spring 18. The operator then rotates the rotating plate 13 180 degrees, with the abutment rod 15 facing downwards. At this point, the operator releases the pull plate 20, and the elastic force of the spring 18 pushes the locking block 19 into another slot 16. Finally, the operator rotates the handle 9, causing the first threaded rod 8 to rotate and descend along the threaded hole 7 until the abutment rod 15 contacts the ground. When all three abutment rods 15 are in contact with the ground, the device is supported, preventing it from tilting. Then, the operator starts the first motor 24, the second threaded rod 22 rotates, the slide plate 25 moves along the limit rod 23, and the measuring ruler body 31 leaves the protective cover 2. Then, the operator starts the cylinder 27, and the output end of the cylinder 27 pushes the lifting plate 28 to rise until the measuring ruler body 31 moves above the protective cover 2. Finally, the operator can start the second motor 29, and the turntable 30 rotates with the measuring ruler body 31, which increases the measuring range of the measuring ruler body 31.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
