[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1 As shown, it is the best embodiment of the present invention, a hydraulic structure detection device, including: a hull 1, a positioning device, a video recording device 31 and a controller 4.

[0033] The hull 1 is provided with a first power device, which drives the hull 1 to move forward; a positioning device is arranged on the hull 1 to determine the position of the hull 1; a recording device 31 is provided above the hull 1 and below the hull 1; the hull 1, the positioning device and the recording device 31 are all connected to the controller 4.

[0034] The controller 4 sends instructions to the positioning device and the video recording device 31 to control the positioning of the positioning device, the video recording device 31 to shoot the above-water and underwater areas, and receives data from the positioning device and the video recording device. The controller can also control the hull 1 to start and move to the area to be tested.

[0035] The hydraulic structure detection device of the present invention arranges a positioning device and a recording device 31 on the hull 1, and remotely controls the movement of the hull 1 through a controller 4, controls the positioning device to locate and draw an underwater map, and controls the recording device 31 to shoot and record the conditions of the above-water and underwater buildings. The obtained data is summarized to the controller 4 for unified processing. The detection coverage is wide, the detection results are relatively accurate and comprehensive, and personnel on shore command and operate through the controller, which has high safety.

[0036] In order to facilitate the underwater video recording device 31 to record, the video recording device 31 below the hull 1 is set in a torpedo-shaped shell 5, and the torpedo-shaped shell 5 is connected to the hull 1 through a rope 61. The torpedo-shaped shell 5 refers to a shell with a torpedo shape. The shell is set in the torpedo shape, which can effectively reduce the water resistance during the process of the hull 1 moving in the water, and is convenient for moving shooting. The rope 61 can be a communication cable, which is convenient for signal transmission between the video recording device 31 and the searchlight 52.

[0037] The head of the torpedo-shaped shell 5 is provided with a protective cover, which is made of transparent material. The video recording device 31 is arranged in the protective cover. The video recording device 31 is arranged in the transparent protective cover at the head of the torpedo-shaped shell 5 to facilitate shooting of the traveling direction area.

[0038] The positioning device includes: a GPS locator 21 and a sonar. The GPS locator 21 is arranged above the hull 1, and the sonar is arranged below the hull 1. The GPS locator 21 can realize real-time positioning. The hull 1 travels to the area to be measured according to the positioning data of the GPS locator 21.

[0039] The hydraulic structure detection device further includes a searchlight 52, which is arranged at the front of the torpedo-shaped housing 5, connected to the controller 4, and facing the traveling direction of the hull 1. The underwater environment is complex and the light is poor. By arranging the searchlight 52 to illuminate the area to be tested, the data captured by the video recording device 31 is clear and easy to use.

[0040] The first power device includes a first propeller 11 arranged at the rear of the hull 1, and the first propeller 11 rotates to drive the hull 1 to move forward. The first power device includes a motor, which is connected to the first propeller 11 through the output shaft of the motor, driving the first propeller 11 to rotate, thereby driving the hull 1 to move forward.

The second driving device includes a motor, which is connected to the second propeller 51 through the output shaft of the motor, and drives the second propeller 51 to rotate, thereby driving the torpedo-shaped shell 5 to move underwater. By setting the second propeller 51 and the first propeller 11 to rotate in the same direction, it is ensured that the torpedo-shaped shell 5 and the hull 1 have the same direction of travel.

[0042] The hull 1 is provided with a take-up drum 6, which is connected to the controller 4, and the other end of the line 61 is connected to the take-up drum 6. By providing the take-up drum, it is convenient to adjust the water immersion depth of the torpedo-shaped shell 5. By adjusting the water immersion depth of the torpedo-shaped shell 5, more positioning data and shooting data can be obtained, thereby improving the detection accuracy.

[0043] The sonar includes a transmitter 22 and a receiver 23, both of which are arranged below the hull 1.

[0044] The controller 4 is provided with a display 41, a lever 42 and a button 43. The lever 42 can be used to control the direction of the hull 1, and the button 43 can be used to send instructions to the positioning device and the recording device 31. The display 41 can display the position of the hull 1 in real time.
