[0002] In karst mountainous areas, reservoir leakage has always been a major challenge for water conservancy engineering. Due to the complexity of karst topography, the investigation of reservoir leakage channels is extremely difficult. Traditional survey methods often have many limitations, making it difficult to accurately determine the location and shape of leakage channels. This is particularly difficult in areas below the reservoir water level around the dam abutment.
[0003] Compared with vertical drilling, the use of inclined drilling to find leakage channels in reservoirs in karst mountainous areas can penetrate potential leakage areas from different angles, more comprehensively detect the complex geological conditions around the reservoir and underwater, and greatly increase the probability of discovering leakage channels. Through inclined borehole photography, the geological characteristics and possible signs of leakage in the hole can be visually observed. Combined with advanced inclinometer technology, the location, orientation and other detailed information of the leakage channel can be accurately recorded. At present, the equipment involved in inclinometer or photography technology in borehole exploration is often expensive and bulky. Traditional inclinometers or borehole photography equipment can only perform a single task. In addition, due to the complex geological conditions and karst development in karst mountainous areas, the inner wall of the borehole is often uneven. Existing devices that can be placed in the borehole for detection are prone to getting stuck and damaged.
[0004] In view of this, in order to solve the above problems, the utility model proposes a device that is convenient for underwater inclined drilling photography, which can provide more accurate and intuitive information for the exploration of leakage channels, and in engineering practice, the pulley assembly can be used to overcome the problem of equipment jamming caused by the uneven inner wall of the borehole.

A fiber optic gyroscope 5 is provided in the cylinder 1 on the side of the counterweight block 4 away from the sealing component 2, and a wire tube 102 passes through the sealing component 2 and the counterweight block 4 respectively and extends to the outside of the cylinder 1. The wire tube 102 is used to accommodate the power line and signal line of the fiber optic gyroscope 5 and the power line and signal line of the camera 6. A plurality of groups of pulley telescopic assemblies 3 are provided at intervals on the circumferential direction of the outer wall of the cylinder 1, wherein pulley telescopic assemblies 3 are provided in the four directions of front, back, left and right respectively, for better balance.
[0022] Preferably, multiple sets of pulley telescopic assemblies 3 are provided on the circumference of the upper and lower side walls of the cylinder 1.
[0023] The preferred pulley telescopic assembly 3 includes a directional roller 301, a telescopic hinge 302, a support 303 and a fixing bolt 304. Two supports 303 are provided on the side wall of the cylinder 1 along its axis. The supports 303 are welded to the cylinder 1. The directional roller 301 is arranged between the two supports 303. A telescopic hinge 302 is provided between the directional roller 301 and the two supports 303. The telescopic hinge 302 and the support 303 are detachably connected by a fixing bolt 304.
[0024] The telescopic hinge 302 is preferably a straight stainless steel hinge.
[0025] Preferably, a scale 101 is provided on the outside of the wire tube 102 to record the depth of descent of the cylinder 1 and calculate the corresponding position in combination with the data recorded by the fiber optic gyroscope 5 .
[0026] The preferred sealing assembly 2 includes a curved sealing cover 201, an upper sealing cover 202 and a lower sealing cover 203. The upper sealing cover 202 and the lower sealing cover 203 are respectively arranged inside the upper and lower ends of the cylinder 1. The curved sealing cover 201 is arranged on the end of the cylinder 1 on the upper side of the upper sealing cover 202, the camera 6 is arranged on the end of the cylinder 1 on the side of the lower sealing cover 203, and the counterweight block 4 is arranged in the cylinder 1 on the side of the lower sealing block away from the camera 6.

[0027] A transparent protective cover 7 is preferably provided on the end of the cylinder 1 on the lower side of the lower sealing cover 203, and the camera 6 is arranged in the middle of the transparent protective cover 7, which can ensure that the camera head 6 is not damaged by falling blocks from the hole wall or hitting rocks when the water is turbid and cannot be photographed and observed during the descent process, while also blocking the line of sight.
[0028] The transparent protective cover 7 is preferably made of hardened glass.
[0029] The working principle of this utility model is as follows: first, after drilling the inclined boreholes arranged in the potential leakage areas on both sides of the reservoir dam abutment, the device is connected to the fiber optic gyro tilt data real-time collector and the USB camera real-time display mobile APP to check whether the equipment is operating normally; the device is placed in the inclined borehole at a relatively uniform speed (3~10m / min), and the hole wall, water level and borehole deviation are observed and recorded in real time.
[0030] Among them, such as Figure 2 As shown, when drilling holes of different diameters, the relative distances of the pulley telescopic assembly 3 in the front, back, left, and right directions can be adjusted to adapt to the size of the hole diameter. Then, the device is placed in the hole and lowered at a constant speed, and the hole wall, water level and hole deviation are observed and recorded in real time; Figure 3 As shown, when the hole wall is uneven, the multiple sets of pulley telescopic assemblies 3 can prevent it from getting stuck during the descent process, so that each directional roller 301 can move along the hole wall without hindrance; Figure 4 As shown, when continuously descending in the inclined borehole to a potential leakage channel, such as a cave or crack, the descending device is paused, and the situation of the potential leakage channel is observed and recorded by the 180° camera 6, the relative orientation and position of the potential leakage point from the borehole mouth is recorded by the fiber optic gyroscope 5, and the distance is recorded by the scale 101 set on the outside of the wire tube 102.
[0031] In addition, the device continues to descend in the inclined borehole, causing the water to become turbid. The device can be lowered by slowing down the descent speed or temporarily stopping the device to descend, ensuring that the water has a high clarity for observation by the camera 6.
