Description

Technical Field

[0001] This utility model specifically relates to an underwater river topography detection device, belonging to the field of underwater detection technology. Background Technology

[0002] Underwater channel topographic surveying refers to the measurement and mapping of the horizontal position and elevation of underwater channels using various technologies and equipment to understand the channel's topographic features. This work is of great significance in engineering surveying, primarily used to create underwater topographic maps that help understand the channel's shape, depth, and bottom characteristics.

[0003] However, the existing detection devices have a single direction of travel, which makes it difficult to control the direction and position of the device underwater. This further limits the detection range and affects the overall efficiency of the detection operation. The devices are also less applicable and cannot meet the needs of the market. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an underwater river topography detection device to solve the problem of the single driving direction mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an underwater riverbed topography detection device, comprising a housing, an inner frame inside the housing, a sealed chamber mounted on the inner frame, an upper drive cylinder at the top of the inner frame, and two sets of side drive cylinders on the sides of the inner frame; a support plate on the inner frame, a motor a mounted at the top of the support plate, a paddle blade at the top of the drive shaft of motor a, an output shaft at the top of the drive shaft of motor a, and a cutting blade mounted at the top of the output shaft; a motor b at the top of the housing, a rudder plate at the bottom of the drive shaft of motor b, and multiple sets of annular blades on the outer side of the rudder plate.

[0006] Furthermore, a PCB panel is installed inside the sealed chamber, and a probe is installed on the PCB panel.

[0007] Furthermore, an adjustment rod is connected through the outer casing.

[0008] Furthermore, two sets of sensors are provided at the bottom of the housing.

[0009] Furthermore, baffles are installed at both ends of the upper drive cylinder and the two sets of side drive cylinders, and water outlet holes are provided on the baffles.

[0010] Furthermore, the cutting blade is close to the baffle and is used to cut debris that is piled up and tangled on the baffle.

[0011] Furthermore, multiple sets of the annular blades are linearly distributed on the outer wall of the rudder plate.

[0012] The beneficial effects of this utility model are as follows: Considering the problem of the single direction of travel mentioned in the background technology, the motors a inside the upper drive cylinder and the two sets of side drive cylinders drive the blades to rotate when started. The forward and reverse rotation of the blades realizes the overall forward and backward movement and lifting and lowering of the device underwater. The motor b drives the rudder plate to rotate, and the movement direction of the device is adjusted by adjusting the angle of the rudder plate, so as to realize the movement of the underwater detection operation. During the movement, when water plants or impurities come into contact with the cylinder, the cutting blades cut the debris accumulated on the baffle. Multiple sets of annular blades on the rudder plate clean the impurities on the rudder plate, so as to realize the underwater detection function of the device. Attached Figure Description

[0020] The technical solution of this utility model is further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5This utility model provides a technical solution: an underwater river topography detection device, including a shell 1, an inner frame 2 inside the shell 1, a sealed chamber 3 installed on the inner frame 2, an upper drive cylinder 8 at the top of the inner frame 2, and two sets of side drive cylinders 9 on the sides of the inner frame 2; a support plate 12 is provided on the inner frame 2, a motor a13 is installed at the top of the support plate 12, a blade 14 is provided at the top of the drive shaft of the motor a13, an output shaft 15 is also provided at the top of the drive shaft of the motor a13, and a cutting blade 16 is installed at the top of the output shaft 15; a motor b17 is provided at the top of the shell 1, a rudder plate 18 is provided at the bottom of the drive shaft of the motor b17, and multiple sets of annular blades 19 are provided on the outer side of the rudder plate 18.

[0022] The upper drive cylinder 8 and the two sets of side drive cylinders 9 are each equipped with a motor a13. When the motor a13 is started, it can drive the blade 14 to rotate. The forward and reverse rotation of the blade 14 realizes the overall forward and backward movement and lifting and lowering of the device underwater. The motor b17 drives the rudder plate 18 to rotate, and the movement direction of the device is adjusted by adjusting the angle of the rudder plate 18.

[0023] Furthermore, a PCB panel 4 is installed inside the sealed chamber 3, and a probe head 5 is installed on the PCB panel 4.

[0024] The PCB panel 4 includes circuit components and power supply, and the probe 5 detects the underwater environment.

[0025] Furthermore, an adjusting rod 6 is connected through the outer casing 1.

[0026] The adjusting rod 6 is connected to the sealed chamber 3 and locked by two sets of nuts on the outside, allowing the detection angle of the probe head 5 to be adjusted before detection.

[0027] Furthermore, two sets of sensors 7 are provided at the bottom of the outer casing 1.

[0028] Among them, two sets of sensors 7 are used to detect water depth and avoid collisions.

[0029] Furthermore, baffles 10 are installed at both ends of the upper drive cylinder 8 and the two sets of side drive cylinders 9, and water outlet holes 11 are opened on the baffles 10.

[0030] Among them, the baffle 10 is used to protect both ends of the cylinder to prevent underwater weeds and other debris from entering the electric equipment and affecting its operation.

[0031] Furthermore, the cutting blade 16 is pressed against the baffle 10 and is used to cut debris that is piled up and wrapped around the baffle 10.

[0032] The cutting blade 16 rotates synchronously with the paddle 14, thereby cutting weeds and other debris and ensuring the unobstructed flow of the outer baffle 10.

[0033] Furthermore, multiple sets of annular blades 19 are linearly distributed on the outer wall of the rudder plate 18.

[0034] The outermost edge of the ring-shaped blade 19 is the cutting edge, which can cut aquatic plants in conjunction with the shaking caused by the water flow during the journey, thus preventing aquatic plants and debris from getting tangled on the rudder plate 18.

[0035] Working principle: After being submerged, the motors a13 inside the upper drive cylinder 8 and the two sets of side drive cylinders 9 drive the propeller 14 to rotate when started. The forward and reverse rotation of the propeller 14 realizes the overall forward and backward movement and lifting and lowering of the device underwater. The motor b17 drives the rudder plate 18 to rotate, and the direction of movement of the device is adjusted by adjusting the angle of the rudder plate 18, so as to realize the movement of underwater exploration operations.

[0036] During operation, when weeds or impurities come into contact with the cylinder, the cutting blade 16 cuts the debris accumulated on the baffle 10, and the multiple sets of annular blades 19 on the rudder plate 18 clean the impurities on the rudder plate 18, so as to realize the underwater detection function of the equipment.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
