[0024] See also Figure 1-7 The utility model provides an underwater observation device, including an electric telescopic rod 1, a support rod 2 is fixedly arranged on the top of the electric telescopic rod 1, a bracket 4 is movably arranged on the surface of the support rod 2 through two spherical joints 3, a display screen 5 is installed on the bracket 4, a camera 6 is arranged at the bottom of the electric telescopic rod 1, the camera 6 is electrically connected to the display screen 5, a control box 17 is fixedly arranged on the top of the electric telescopic rod 1, the control box 17 and the display screen 5 are connected through a wireless signal, three legs 7 are equidistantly hinged on the surface of the electric telescopic rod 1, and a rubber base 16 is fixedly arranged at the end of the leg 7.

[0025] See also Figure 1 , 2 When in use, the electric telescopic rod 1 can be placed vertically on the ground through the three open legs 7, and then the camera 6 passes through the sewer or the hole of other observation areas by driving the electric telescopic rod 1. The electric telescopic rod 1 can rotate and extend, so as to adjust the depth and shooting range of the camera 6 in the area to be observed. The setting of the rubber base 16 can increase the friction between the legs 7 and the ground, so as to facilitate the stable placement of the electric telescopic rod 1.

[0026] It should be noted that a radar sensor is also installed at the end of the electric telescopic rod 1, and the radar sensor is connected to the electric telescopic rod through a control box. The setting of the radar sensor can enable the electric telescopic rod 1 to drive the camera 6 to automatically stop at a distance of 20 cm from the bottom of the pipe or the water surface to prevent water from entering the camera 6 or touching the bottom of the pipe and causing damage. In addition, since the display screen 5 is connected to the control box 17 through wireless signal transmission, in this embodiment, the display screen 5 can be accessed through mobile devices such as mobile phones and tablets, and the camera 6 is also connected to the control box 17 through wireless transmission to realize wireless transmission of image signals from the camera 6 to the control box 17 and then to the display screen 5.

[0027] A connecting seat 20 is fixedly provided at the bottom end of the electric telescopic rod 1 , a lamp holder 21 is installed below the connecting seat 20 , three through holes 22 for installing lighting lamps are equidistantly provided on the surface of the lamp holder 21 , and the camera 6 is fixedly provided at the bottom of the lamp holder 21 .

[0028] See also Figure 1 , 2 And 4, the lighting lamp inside the through hole 22 can be used in the area to be observed, and can provide a light source to illuminate the area to be photographed when the camera 6 is shooting, and the three through holes 22 are equidistantly distributed on the surface of the lamp holder 21, so that the three lighting lamps can evenly illuminate the nearby area with the focus of the lamp holder 21 as the center of the circle.

[0029] A limiting mechanism for fixing the whole is provided at the bottom of the leg 7. The limiting mechanism includes a rotating shaft 8, a connecting arm 9, a base plate 10 and a rubber support block 11. The connecting arm 9 is vertically fixed to the surface of the base plate 10, the rotating shaft 8 is fixedly arranged on the surface of the leg 7, one end of the connecting arm 9 is rotatably arranged on the surface of the rotating shaft 8, and the rubber support block 11 is movably arranged on the surface of the base plate 10 through an adjusting mechanism. The adjusting mechanism includes a movable seat 12 and a side plate 13. The side plate 13 is vertically fixed to the surface of the movable seat 12, the movable seat 12 is attached to the surface of the base plate 10, the side plate 13 is attached to the side of the base plate 10, the side plate 13 is slidably arranged on the side of the base plate 10 through a limiting structure, and the rubber support block 11 is fixedly arranged below the movable seat 12. The limiting structure includes a slide groove 14 and a limiting protrusion 15. The slide groove 14 is arranged on the side of the base plate 10, the limiting protrusion 15 is fixedly arranged on the surface of the side plate 13, and the limiting protrusion 15 is slidably arranged inside the slide groove 14.

[0030] See also Figure 5 and 6 When the angle of the legs 7 is fixed and opened, the base plate 10 can be adjusted to an angle perpendicular to the ground through the setting of the rotating shaft 8 and the connecting arm 9, and then the rubber support block 11 is pressed through the movable seat 12, so that the rubber support block 11 is placed on the ground, increasing the static friction between the whole and the ground.

[0031] It should be noted that when the movable seat 12 is pressed, the movable seat 12 can drive the side plate 13 to move synchronously on the side of the base plate 10, and the side plate 13 can drive the limiting protrusion 15 to slide inside the slide groove 14. The setting of the limiting protrusion 15 and the slide groove 14 can not only guide the movement direction of the movable seat 12, but also prevent the movable seat 12 from falling off the surface of the base plate 10. Since the movable seat 12 can drive the rubber support block 11 to change its height, even if the ground is partially uneven, the overall stable placement can still be achieved. In this embodiment, a threaded rod can be added between the movable seat 12 and the base plate 10, and the height adjustment of the movable seat 12 can be achieved by rotating the threaded rod.

[0032] A semicircular receiving groove 18 is provided on the surface of the base plate 10 . The diameter of the semicircular receiving groove 18 is the same as the diameter of the supporting leg 7 . A locking protrusion 19 is integrally formed on the inner wall of the semicircular receiving groove 18 .

[0033] See also Figure 7 When not in use, by rotating the connecting arm 9, the base plate 10 can drive the semicircular accommodating groove 18 to contact the leg 7. At this time, the surface of the leg 7 just fits into the semicircular accommodating groove 18, and in the part of the locking protrusion 19, since the diameter of the locking protrusion 19 is smaller than the diameter of the leg 7, the leg 7 can squeeze the locking protrusion 19 when passing through the locking protrusion 19. In this embodiment, the material of the locking protrusion 19 is set to rubber or silicone. After passing through the deformed locking protrusion 19, the locking protrusion 19 can restore its original shape, thereby clamping it from the other side of the leg 7, so that the base plate 10 can be fixed on the surface of the leg 7.
