[0028] See also Figures 1 to 3 This embodiment provides a camera straightening device, which can ensure the stability of the camera moving in the pile foundation hole and ensure the shooting quality of the camera. The camera straightening device includes a fixing frame 1 and a straightening mechanism. The fixing frame 1 is configured to be connected to the camera. The straightening mechanism includes a plurality of straightening components 2, and the plurality of straightening components 2 are arranged at intervals along the circumference of the fixing frame 1. The fixing frame 1 is provided with an installation cavity 131 along the radial direction of the pile foundation hole. The straightening component 2 includes an elastic member 21 and an abutment portion. The elastic member 21 is arranged in the installation cavity 131. One end of the abutment portion is slidably arranged in the installation cavity 131 and is connected to the elastic member 21. The elastic member 21 always has a tendency to drive the abutment portion to move out of the installation cavity 131, so that the abutment portion can abut against the inner wall of the pile foundation hole.

[0029] See also Figure 1When used, first connect the camera to the straightening device, then press the abutting part inward to retract it into the installation cavity 131 and compress the elastic member 21 to store energy, and then place the straightening device in the pile foundation hole. Since the pile foundation is vertically arranged on the ground, the straightening device can move downward along the inner wall of the pile foundation hole under the action of gravity. During the movement, the abutting part always has a tendency to move out of the installation cavity 131 under the action of the restoring force of the elastic member 21, so that the abutting part can always abut against the inner wall of the pile foundation hole, thereby ensuring the stability of the camera when moving in the pile foundation hole, and then ensuring the shooting quality of the camera. Multiple straightening components 2 enable the device to contact the inner wall of the pile foundation hole at multiple points, further ensuring the stability of the camera movement. The setting of the straightening component 2 can also enable the device to adapt to the straightening of cameras in pile foundation holes of different specifications. The installation cavity 131 provides an installation space for the straightening component 2, and can also provide a guiding effect for the abutting part to ensure the stability of the sliding of the abutting part.

[0030] Optionally, the elastic member 21 is a spring, which has high elasticity, is easy to obtain, and has low cost.

[0031] Optionally, the abutment portion includes a connecting rod 22 and a roller 23 rotatably connected to the connecting rod 22, and one end of the connecting rod 22 away from the roller 23 is slidably disposed in the mounting cavity 131 and connected to the elastic member 21, and the roller 23 can roll in contact with the inner wall of the pile foundation hole. During the movement, the roller 23 can roll in contact with the inner wall of the pile foundation hole, thereby reducing the friction between the abutment portion and the inner wall of the pile foundation hole, and ensuring the stability and smoothness of the straightening device during movement.

[0032] Optionally, a driving member is also included, and the output end of the driving member is connected to the roller 23 of any straightening assembly 2, and is used to drive the roller 23 to rotate. The roller 23 can be driven to rotate by starting the driving member, thereby driving the straightening device and the camera to move, thereby preventing the straightening device from getting stuck in the pile foundation hole. Optionally, the driving member is a motor, and the remote control of the motor can automatically control the movement of the straightening device. It can be understood that by setting the driving member, the present device can also be used to straighten the camera for detection in a pipe that is not vertically arranged. Optionally, two connecting ears are relatively arranged at one end of the connecting rod 22 away from the elastic member 21, and a rotating shaft is concentrically arranged on the roller 23, and the two ends of the rotating shaft are respectively rotatably connected to the two connecting ears, thereby realizing the rotational connection between the roller 23 and the connecting rod 22.

[0033] Preferably, see Figure 2The installation cavity 131 includes a first cavity section 1311 and a second cavity section 1312 that are connected. The inner diameter of the first cavity section 1311 is larger than the inner diameter of the second cavity section 1312. One end of the abutting portion is slidably disposed in the first cavity section 1311, and the end of the elastic member 21 away from the abutting portion is connected to the inner wall of the second cavity section 1312. The second cavity section 1312 can better match the elastic member 21 to provide a good guiding effect for the elastic member 21. During the movement of the camera, the elastic member 21 can extend or retract into the second cavity section 1312, so that the elastic member 21 can absorb or release energy more concentratedly, thereby ensuring the stability of the abutting portion when in contact with the inner wall of the pile foundation hole.
