[0024] The in-pile-hole detection device of the embodiments of the present utility model will be specifically described below with reference to the accompanying drawings.

[0025] As Figure 1 shown, the in-pile-hole detection device according to the embodiments of the present utility model includes: a bracket 1, a counter 2, a camera assembly 5, and a video receiving, displaying, and recording machine 6; the counter 2 is installed on the bracket 1, a first cable 3 is connected to the counter 2, the counter 2 is used to record the moving distance of the first cable 3, the counter 2 is connected to a depth display 4, and the depth display 4 is used to display the detection data of the counter 2; the camera assembly 5 is installed at one end of the first cable 3, and the camera assembly 5 is used to photograph the state inside the pile hole; the video receiving, displaying, and recording machine 6 is installed at the other end of the first cable 3, and the video receiving, displaying, and recording machine 6 is connected to the depth display 4 by a second cable 7. The video receiving, displaying, and recording machine 6 is used to receive and record the content photographed by the camera assembly 5 and the detection data of the counter 2.

[0026] In this embodiment, after the camera assembly 5 is placed in the pile hole, the meter 2 is used to connect the depth display machine 4 to record the moving distance of the first cable 3 in real time. When the camera assembly 5 reaches the required depth, the camera assembly 5 shoots the state of the inner wall of the pile in the pile hole, and transmits the shot content to the video receiving display recorder 6. When a defect is photographed, since the video receiving display recorder 6 is also connected to the depth display machine 4, the specific depth photographed by the camera assembly 5 at this time can be determined to accurately determine the specific location of the pile defect, and whether the defect is the connection between two piles and whether it affects the quality of the pile is determined according to the depth position, thereby improving the accuracy of the evaluation. In addition, the video receiving display recorder 6 can store the shot content for subsequent tracing to improve the validity of the data.

[0027] The camera assembly 5 is provided with a positioning bar 8 , and the positioning bar 8 is provided with a positioning line, and the positioning line is used to determine the initial recording position of the meter 2 .

[0028] The camera assembly 5 includes a camera, and the positioning bar 8 is located at the upper end of the camera to avoid blocking the camera. The camera assembly 5 is located in the middle of the positioning bar 8 to avoid the positioning bar 8 causing the camera assembly 5 to tilt.

[0029] In this embodiment, the positioning line is at a certain distance from the center point of the camera shooting. Before the camera assembly 5 is placed in the pile hole, the positioning line is placed on the same horizontal plane as the upper surface of the pile. At this time, the position of the first cable 3 is set as the zero position, and the moving distance of the first cable 3 is recorded from here. When the defect position is confirmed later, the moving distance of the first cable 3 recorded by the depth display machine 4 is added to the distance from the positioning line to the center point of the camera shooting, and finally the specific position of the defect is obtained, thereby achieving the effect of precise positioning.

[0030] The positioning bar 8 is a metal block or other heavy material to increase the weight of the camera assembly 5 and facilitate the camera assembly 5 to sink when there is water in the reference hole.

[0031] The camera is a 360-degree rotating camera, and the camera rotates in the horizontal direction to shoot the entire connection of the pile hole and the pile through rotation.

[0032] The positioning bar 8 is a hollow structure. Two telescopic mechanisms are arranged inside the positioning bar 8. The two telescopic mechanisms are arranged back to back and telescope in the horizontal direction.

[0033] In this embodiment, the telescopic mechanism can be an electric telescopic rod. When the camera assembly 5 reaches the required depth, the telescopic mechanism is controlled so that the two telescopic mechanisms are against the inner wall of the pile hole to fix the direction of the camera assembly 5. During the rotation of the camera, the entire camera assembly 5 is prevented from shifting or twisting to ensure that the camera can complete 360-degree horizontal shooting.

[0034] There is an illumination mechanism above the imaging component 5.

[0035] It includes a storage battery 9. Both the depth display 4 and the video receiving, displaying and recording machine 6 are electrically connected to the storage battery 9. Due to site problems, the power supply is usually at a certain distance from the foundation pile. When the foundation pile is far from the power supply, a relatively long power cord is needed to connect the power supply. During the detection process, it is very easy to cause unstable power connection due to pulling. By setting the storage battery 9, the length requirement of the power cord is shortened, so the phenomenon of the power cord being pulled is reduced, and the power supply stability is improved.

[0036] The bracket 1 is a tripod.

[0037] The length meter 2 and the depth display 4 are connected by a third cable.

[0038] In the description of this specification, the descriptions with reference to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
