[0028] The rotating mechanism 2 comprises a first fixed sleeve 22 vertically opposite mounted on the top surface of the base 1, a rotating rod 23 is mounted between the two first fixed sleeves 22 through a bearing matched therewith, the rotating rod 23 is axially and symmetrically fixed with a rotating plate 25 at the end, and the two rotating plates 25 are vertically fixed with the mounting plate 3 at the end face; a worm gear 24 is axially fixed on the middle part of the rotating rod 23, and the worm gear 24 is in transmission engagement with a worm 21 rotatably arranged on the base 1.
[0029] By adopting the above technical scheme, the device is provided with the rotating mechanism 2 on the base 1 and connected with the mounting plate 3, so that the mounting plate 3 can be horizontally adjusted; the movable plate 4 is inclinedly arranged on the mounting plate 3, and the angle is 45°, which is to enable the plane mirror 5 to reflect the bottom picture to the camera at a correct angle, and to realize that the ordinary plane mirror 5 replaces the right-angle prism to complete the camera shooting of the bottom picture.
[0030] Since the experimental site may be uneven, the traditional right-angle prism is easily affected when placed, resulting in distortion of the reflected image; and the device can be quickly adjusted to be horizontal after the mounting plate 3 is rotated by a certain angle according to the actual placement of the base 1 through the flexible adjustment of the rotating mechanism 2, so as to ensure that the plane mirror 5 always maintains a correct reflection angle, thereby obtaining a clear bottom picture.
[0031] The rotating mechanism 2 is combined by the first fixed sleeve 22, the rotating rod 23, the worm gear 24 and the worm 21, so as to realize flexible horizontal adjustment of the mounting plate 3, and the mounting plate 3 can be quickly rotated and adjusted to be horizontal, which is simple in operation, thereby ensuring that the reflection of the plane mirror 5 is horizontally emitted, avoiding the difference between the reflected image of the mirror and the picture image of the real bottom caused by the uneven bottom of the placed three-prism in the use of the existing three-prism, and the problem that the three-prism is usually held to adjust and rotate after being placed, thereby ensuring the consistency of the reflected image of the mirror and the picture image of the real bottom.

[0033] By adopting the above technical scheme, the L-shaped groove 11 is arranged to make full use of the space below the base 1, reduce the floor area of the device, and make the device more compact and portable.
[0034] The worm 21 is installed at both ends of the horizontal part of the groove 11 through bearings, which not only ensures the stability and rotation flexibility of the worm 21, but also makes the transmission engagement between the worm 21 and the worm gear 24 more reliable. The bottom of the worm gear 24 extends into the vertical part of the groove 11 and is closely engaged with the worm 21.

[0041] By adopting the above technical scheme, the pivot connection between the movable plate 4 and the mounting plate 3 allows the movable plate 4 to rotate or tilt within a certain range.
[0042] The support plate 6 serves as a connecting piece between the movable plate 4 and the mounting plate 3, not only supporting the movable plate 4, but also ensuring that the movable plate 4 always maintains an inclination angle of 45°.
[0043] As shown in Figure 2 and Figure 3 , the bottom surface of the movable plate 4 is provided with a receiving groove 42 for accommodating the support plate 6, the top of the receiving groove 42 is transversely rotatably connected with a fixed shaft 43, the top of the support plate 6 is fixedly connected with the fixed shaft 43, and the bottom of the support plate 6 is inserted into the limiting groove 32 provided on the top surface of the mounting plate 3.

[0045] The support plate 6 is connected with the bottom surface of the movable plate 4 through the fixed shaft 43, which ensures that the support plate 6 can maintain a stable posture when unfolded, providing reliable support for the movable plate 4 and the plane mirror 5 on it;
[0046] The design of the limiting groove 32 allows the support plate 6 to be accurately inserted into the corresponding position on the top surface of the mounting plate 3 when unfolded, thereby realizing stable fixation; this limiting and positioning mechanism not only improves the stability and reliability of the device, but also ensures that the plane mirror 5 can always maintain the correct inclination angle, thereby shooting clear and distortion-free reflected images.

[0049] Example Three
[0050] In combination with Figures 1-4 , on the basis of the above embodiment, the present embodiment further gives the following contents:
[0051] In the present embodiment, as shown in Figures 1-4 , the plane mirror 5 is clamped and fixed by the adjusting mechanism 7 symmetrically arranged on both sides of the mounting groove 41;
[0052] The adjusting mechanism 7 comprises a pull rod 71 vertically slidingly penetrating the side of the corresponding mounting groove 41, and the inner end of the pull rod 71 is vertically fixed with an L-shaped plate 72 for clamping the plane mirror 5; an elastic spring 73 is axially sleeved on the pull rod 71, and one end of the elastic spring 73 is connected with the outer side wall of the L-shaped plate 72, and the other end is connected with the inner side wall of the corresponding mounting groove 41.
[0053] By adopting the above technical scheme, when plane mirrors 5 of different sizes need to be used, the device cannot be used to install plane mirrors 5 of different sizes, and therefore the front and rear sides of the movable plate 4 are provided with adjusting structures 7.
[0054] The adjusting mechanism 7 is vertically slidingly penetrated on the side of the mounting groove 41 through the pull rod 71, so that the L-shaped plate 72 can be flexibly moved in the mounting groove 41, thereby realizing clamping and releasing of the plane mirror 5; the elastic spring 73 is arranged to enable the L-shaped plate 72 to produce elastic deformation when clamping the plane mirror 5, thereby adapting to plane mirrors of different sizes and shapes.
[0055] The design of the adjusting mechanism 7 simplifies the installation and dismounting process of the plane mirror 5; the user can easily clamp and release the plane mirror 5 without using complex tools or steps; this design not only improves the convenience of operation, but also reduces the difficulty and time cost of operation.
[0056] As shown in Figures 1-3 The bottom surface of the base 1 is vertically and symmetrically provided with a placing leg at each corner.
[0057] By adopting the above technical scheme, the design of the placing leg enables the device to be stably placed on the ground, effectively preventing the device from shaking or toppling due to uneven ground or external force;
[0058] The placing leg usually has a certain length and adjustability, which enables the device to adapt to different heights and uneven ground within a certain range.
[0059] The placing leg is in direct contact with the ground, thereby avoiding direct friction and collision between the bottom surface of the base 1 and the ground; this helps to protect the bottom surface of the device from damage and prolong the service life of the device.
[0060] The working principle and use process of the device are as follows:
[0061] In use, first, the device is placed in a suitable position to ensure that the base 1 is stable. Then, the horizontal position of the mounting plate 3 is adjusted through the rotating mechanism 2; this can be achieved by shaking the shaking hand 211 at one end of the worm 21, and the transmission meshing connection between the worm 21 and the worm gear 24 enables the rotating rod 23 to drive the rotating plate 25 and the mounting plate 3 to rotate to the required angle.
[0062] After the installation plate 3 is adjusted to the horizontal position, the movable plate 4 keeps a 45° angle with the installation plate 3; the inclined surface of the movable plate 4 is provided with a mounting groove 41 for fixing the plane mirror 5. The plane mirror 5 is clamped and fixed by the adjusting mechanism 7 on both sides of the mounting groove 41. Specifically, pulling the pull rod 71 makes the L-shaped plate 72 loose, the plane mirror 5 is placed in the mounting groove 41, then the pull rod 71 is released, the elastic force of the spring 73 pushes the L-shaped plate 72 to approach the plane mirror 5 until clamping is stable.
[0063] If it is necessary to adjust the angle of the movable plate 4 or to maintain, it can be realized through the support plate 6; by rotating the support plate 6, the angle of the movable plate 4 can be adjusted or it can be stored conveniently.
[0064] After the installation and angle adjustment of the plane mirror 5 are completed, the camera can be vertically downward to shoot the bottom picture reflected by the plane mirror 5.
[0065] During the experiment, if it is necessary to adjust the shooting angle or position, the above steps can be repeated. The whole device is reasonable in design and convenient in operation, and can significantly improve the accuracy and efficiency of the visual measurement.
[0066] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
