Description

Technical Field

[0001] The utility model relates to the technical field of underwater topography measurement, in particular to an underwater topography measurement device. Background Art

[0002] Underwater topography is a specific type of engineering surveying. It measures the plane position and elevation of the seafloor points in rivers, lakes, reservoirs, harbors and offshore waters to draw underwater topographic maps. Depth measurement uses instruments such as sounding rods, sounding hammers and echo sounders. The bottom elevation is calculated based on the results of depth measurement and water level observation. Finally, isobaths are used to represent the bottom topography. Echo sounders are widely used in modern times, and their accuracy and efficiency have been greatly improved.

[0003] The existing detection method usually uses a rubber boat or an unmanned boat carrying an echo sounder to measure the underwater terrain. When using an unmanned boat, the unmanned boat is relatively small. The unmanned boat is prone to swaying and tilting when traveling on the water. The echo sounder will tilt with the unmanned boat, affecting the measurement accuracy and efficiency of the echo sounder. The existing processing method is to increase the stability of the ship, reduce the tilt and swaying, and avoid excessive inclination of the echo sounder. However, when the ship is traveling on the water, it is inevitable that it moves with the water waves. The echo sounder moves with the unmanned boat, affecting the detection accuracy. Summary of the invention

[0004] In view of the above problems, the purpose of the utility model is to provide an underwater topographic measuring device to solve the problem that unmanned boats are prone to swaying and tilting when traveling on the water. The echo sounder will tilt with the unmanned boat, affecting the measurement accuracy and efficiency of the echo sounder. The existing processing method is to increase the stability of the boat, reduce the tilt and swaying, and avoid excessive inclination of the echo sounder. However, when the boat is traveling on the water, it is inevitable that it moves with the water waves. The echo sounder moves with the unmanned boat, affecting the detection accuracy.

[0005] To achieve the above purpose, the utility model adopts the following technical solution: an underwater topographic measuring device, including a hull and a telescopic motor, an equipment box is installed above the hull through a strut, and a cover is installed above the equipment box through a hinge, an electric paddle is installed at the tail end of the equipment box, a control device is installed inside the equipment box, and a transceiver antenna is arranged above the control device, the telescopic motor is installed in the middle part of the equipment box, and a T-shaped connector is connected to the top of the telescopic motor through a flip shaft, the bottom end of the T-shaped connector is connected to a rotating shaft, and a mounting rod is installed in the middle part of the rotating shaft, an echo sounder is installed at the bottom of the mounting rod, and an angle sensor is installed on the outside of the mounting rod.

[0006] The beneficial effects of the utility model are as follows: when deflection occurs, under the action of gravity, the echo sounder and the mounting rod will rotate along the rotating axis and always remain perpendicular to the ground; when the front and rear angles of the echo sounder change, the telescopic motor drives the T-shaped connecting piece to drive either end of the rotating axis to rise or lower and adjust the echo sounder to a horizontal position. This method can effectively prevent the echo sounder from tilting, thereby ensuring the accuracy of terrain detection.

[0007] To facilitate leveling of the echosounder:

[0008] As a further improvement of the above technical solution: four telescopic motors are symmetrically arranged about the center line of the equipment box.

[0009] As a further improvement of the above technical solution: a lifting and lowering installation structure is formed between the T-shaped connecting piece and the equipment box through a telescopic motor.

[0010] The beneficial effect of this improvement is that the telescopic motor drives the T-shaped connector to raise or lower any end of the rotating shaft to adjust the echo sounder to a horizontal position. This method can effectively prevent the echo sounder from tilting and ensure the accuracy of terrain detection.

[0011] As a further improvement of the above technical solution: a mounting hole is opened on the top of the mounting rod, and rubber pads are installed on both sides of the mounting rod.

[0012] As a further improvement of the above technical solution: the rotating shaft passes through the mounting hole opened at the top of the mounting rod, and a bearing is installed at the connection between the mounting rod and the rotating shaft.

[0013] The beneficial effect of this improvement is that when the hull sways and tilts, the mounting rod rotates along the rotation axis so that the mounting rod remains level with the ground. The bearing can effectively reduce the friction force when the mounting rod rotates. When the deflection angle of the mounting rod is too large and the mounting rod contacts the equipment box, the rubber pads on both sides of the mounting rod can serve as a buffer to reduce the vibration of the mounting rod and the echo sounder.

[0014] To facilitate the partitioning within the device:

[0015] As a further improvement of the above technical solution: a partition board is arranged inside the equipment box.

[0016] The beneficial effect of this improvement is that the partition plate can separate the telescopic motor from the control device to ensure the normal use of the device.

[0017] To facilitate the flipping of the rotation axis:

[0018] As a further improvement of the above technical solution: slots are provided in the equipment box near the two ends of the rotating shaft.

[0019] The beneficial effect of this improvement is that the slot hole can facilitate the change of the angle of the rotating shaft by the telescopic motor through the T-shaped connecting piece.

[0020] To ensure smooth operation of the device:

[0021] As a further improvement of the above technical solution: the equipment box and the hull are arranged parallel to each other.

[0022] The beneficial effect of this improvement is that the parallel arrangement can make the weight distribution of the device uniform and reduce the swaying and tilting of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0029] like Figure 1-4As shown, an underwater topographic survey device includes a hull 1 and a telescopic motor 5, an equipment box 2 is installed above the hull 1 through a strut, and a cover plate 21 is installed above the equipment box 2 through a hinge, an electric paddle is installed at the tail end of the equipment box 2, a control device 4 is installed inside the equipment box 2, and a transceiver antenna 41 is arranged above the control device 4, the telescopic motor 5 is installed in the middle part of the equipment box 2, and a T-shaped connector 51 is connected to the top of the telescopic motor 5 through a flip shaft, the bottom end of the T-shaped connector 51 is connected to a rotating shaft 52, and a mounting rod 53 is installed in the middle part of the rotating shaft 52, and an echo sounder 54 is installed at the bottom of the mounting rod 53 , and an angle sensor 55 is installed on the outer side of the mounting rod 53. When deflection occurs, under the action of gravity, the echo sounder 54 and the mounting rod 53 will rotate along the rotating shaft 52 and always remain perpendicular to the ground. When the front and rear angles of the echo sounder 54 change, the telescopic motor 5 pushes the T-shaped connecting piece 51 to drive any end of the rotating shaft 52 to rise or lower and adjust the echo sounder 54 to a horizontal position. This method can effectively prevent the echo sounder 54 from tilting and ensure the accuracy of terrain detection. Four telescopic motors 5 are symmetrically arranged about the center line of the equipment box 2. The telescopic motor 5 forms a lifting installation structure between the T-shaped connecting piece 51 and the equipment box 2. The motor 5 pushes the T-shaped connector 51 to drive any end of the rotating shaft 52 to rise or fall, thereby adjusting the echo sounder 54 to a horizontal position. This method can effectively prevent the echo sounder 54 from tilting, thereby ensuring the accuracy of terrain detection. The top of the mounting rod (53) is provided with a mounting hole, and rubber pads are installed on both sides of the mounting rod (53). The rotating shaft (52) passes through the mounting hole on the top of the mounting rod (53), and a bearing is installed at the connection between the mounting rod (53) and the rotating shaft (52). When the hull 1 sways and tilts, the mounting rod 53 rotates along the rotating shaft 52, so that the mounting rod 53 remains horizontal with the ground. The bearing can effectively reduce the rotation of the mounting rod 53. Friction, when the deflection angle of the mounting rod 53 is too large, the mounting rod 53 contacts the equipment box 2, and the rubber pads on both sides of the mounting rod 53 can serve as a buffer to reduce the vibration of the mounting rod 53 and the echo sounder 54. A partition board is arranged inside the equipment box 2, and the partition board can separate the telescopic motor 5 from the control device 4 to ensure the normal use of the device. The equipment box 2 is provided with slots near the two ends of the rotating shaft 52, and the slots can facilitate the telescopic motor 5 to push the rotating shaft 52 to change its angle through the T-shaped connector 51. The equipment box 2 and the hull 1 are arranged parallel to each other, and the parallel arrangement can make the weight distribution of the device uniform, which can reduce the swaying and tilting of the device.

[0030] The working principle of the utility model is as follows: when using the device, the device is placed in the water, the device is turned on, and the electric paddle pushes the device to travel on the water surface. During the travel of the device, the echo sounder 54 detects the underwater terrain. During the travel of the device, the angle sensor 55 monitors the angle of the echo sounder 54 in real time. When deflection occurs, under the action of gravity, the echo sounder 54 and the mounting rod 53 will rotate along the rotating shaft 52 and always remain perpendicular to the ground. When the front and rear angles of the echo sounder 54 change, the telescopic motor 5 pushes the T-shaped connector 51 to drive any end of the rotating shaft 52 to rise or lower and adjust the echo sounder 54 to a horizontal position. This method can effectively prevent the echo sounder 54 from tilting and ensure the accuracy of terrain detection.
