Description

Technical Field

[0001] The utility model belongs to the technical field of dam surface appearance measurement, and in particular relates to a protective device of a dam surface appearance measurement robot. Background Art

[0002] In order to allocate water resources, it is often necessary to build dams in rivers and channels for flood control, water supply, irrigation, and hydroelectric power generation. As a very important water conservancy project, it is often necessary to use measuring robots to inspect and measure the shape of the dam to avoid possible disastrous consequences.

[0003] At present, the protective devices of existing dam surface appearance measuring machines are often unable to move with the measuring machines. Once the measuring machines encounter external impacts, they are easily damaged, resulting in data loss of the measuring robots.

[0004] Therefore, in order to address the problem that the protective device of the above-mentioned existing dam surface appearance measuring robot cannot move with the measuring robot, causing the measuring robot to be easily damaged, the protective device is converted into a small transparent protective cover, and the small protective cover is put on the outside of the measuring head to provide real-time protection for the measuring head. Utility Model Content

[0005] In order to overcome the problem that the protective device of the existing dam surface appearance measuring robot cannot move with the measuring robot, resulting in the measuring robot being easily damaged.

[0006] The technical solution of the utility model is: a protective device for a dam surface appearance measuring robot, comprising a mobile vehicle, a measuring head, a supporting platform, a protective cover and a mounting seat; the mobile vehicle is provided with a measuring head, a supporting platform located on the mobile vehicle is provided at the bottom end of the measuring head, a protective cover sleeved on the measuring head is installed on the supporting platform, a mounting seat with four anchor holes is fixedly connected to the bottom end of the protective cover, bolts serving as anchors pass through the anchor holes, and nuts are screwed on the outer sides of the bolts.

[0007] Preferably, by converting the originally fixed protective device into a small transparent protective cover that is sleeved on the outside of the measuring head, the protective cover is installed on the top of the mobile vehicle through a mounting platform. This can provide real-time protection for the measuring head that needs to be moved to measure the appearance of the dam. The protective cover can prevent external impact on the measuring head and ensure the integrity of the measuring head data.

[0008] Preferably, a protective ring is fixedly connected to the bottom end of the support platform, and the bolts inserted into the mounting base and the nuts screwed on the bolts are both located on the inner side of the protective ring. The protective ring can protect the bolts and nuts fixing the transparent protective cover to avoid damage due to the external environment, extend the service life of the anchor, and facilitate the disassembly and assembly of the protective cover.

[0009] Preferably, a telescopic rod is installed on the mobile vehicle, a telescopic column is movably connected inside the telescopic rod, and a support platform is arranged at the top of the telescopic column. The telescopic column moves up and down inside the telescopic rod, thereby driving the support platform installed on the telescopic column to move up and down, thereby changing the height of the support platform and the measuring head installed on the support platform.

[0010] Preferably, a rotating shaft is fixedly connected to the bottom end of the support platform, a storage groove is opened on the inner side of the telescopic column, a transmission element is installed in the storage groove and a No. 1 motor connected to the rotating shaft is installed, and the No. 1 motor drives the rotating shaft and the support platform fixedly connected to the rotating shaft to rotate, thereby changing the angle of the measuring head.

[0011] Preferably, a limiting sleeve is fixedly connected to the telescopic rod, the telescopic column is movably inserted in the limiting sleeve, and a limiting ring located below the limiting sleeve is fixedly connected to the outer side of the telescopic column. The inner diameter of the limiting sleeve is larger than the telescopic column, while the outer diameter of the limiting ring is smaller than the inner diameter of the telescopic rod but larger than the inner diameter of the limiting sleeve, thereby preventing the telescopic column from being completely moved out of the telescopic rod during the upward movement.

[0012] Preferably, a No. 1 bevel gear is installed in the telescopic rod, a threaded rod is fixedly connected to the No. 1 bevel gear, a limiting column is fixedly connected to the telescopic rod, a screw hole matching the threaded rod is opened on the telescopic column, the telescopic column is sleeved on the outside of the limiting column, and the No. 1 bevel gear drives the threaded rod to rotate. Under the restriction of the limiting column, the telescopic column screwed on the threaded rod cannot rotate with the threaded rod, but moves up and down in the telescopic rod.

[0013] Preferably, a No. 2 motor is installed on the mobile vehicle, and a No. 2 bevel gear meshing with the No. 1 bevel gear is installed on the transmission element of the No. 2 motor. The No. 2 bevel gear is arranged in the telescopic rod. The No. 2 motor drives the No. 2 bevel gear to rotate, and the No. 2 bevel gear pushes the meshing No. 1 bevel gear to rotate, so that the threaded rod fixedly connected to the No. 1 bevel gear rotates accordingly.

[0014] Beneficial effects of the utility model:

[0015] 1. By converting the originally fixed protective device into a small transparent protective cover that is sleeved on the outside of the measuring head, the measuring head that needs to be moved to measure the appearance of the dam can be protected in real time. At the same time, the design of the transparent protective cover allows light to penetrate freely without affecting the work of the measuring head. The protective cover can prevent external impact on the measuring head and ensure the integrity of the measuring head data;

[0016] 2. The telescopic column moves up and down in the telescopic rod, thereby changing the support platform installed on the telescopic column and the measuring head installed on the support platform to move up and down, so as to measure the appearance of the dam with a certain height.
