Description

Technical Field

[0001] The present application relates to the field of surveying technology, and more specifically, to an underwater topographic measuring device. Background Art

[0002] Underwater topography measurement is an important part of water conservancy projects. It uses tools such as sounding rods, sounding hammers and echo sounders to measure the position and height of the bottom of rivers, lakes and reservoirs, and then calculates the bottom elevation based on the water depth and water level data, and draws underwater topographic maps with contour lines. This underwater measurement device can measure underwater topography quickly and accurately.

[0003] A document with prior art publication number CN219934958U provides a simple underwater topographic measuring device. In the related technology of the device, by adjusting the length of the rotating support rod assembly and the support angle of the support assembly, the assembly assembly is suspended above the water surface, and then a plumb bob is dropped vertically to the underwater ground as a weight, and the pulley and the GPS mobile station are fixed at the same position on the boat. The length of the measuring rope is measured by reading the position of the GPS mobile station, and the length of the measuring rope is equal to the pole height of the GPS mobile station. The underwater ground position and elevation can be accurately measured by inputting the pole height through the RTK handbook. The measurement efficiency is high and the operation is simple, which is convenient for personnel to move and operate.

[0004] However, the design of the winding and storage mechanism of the device easily causes the measuring rope to be entangled, knotted or loosened during the storage process, which affects the neatness and service life of the measuring rope.

[0005] In view of this, we propose an underwater topographic measurement device. Utility Model Content

[0006] In order to improve the problems raised in the above background technology, the present application provides an underwater topographic measurement device.

[0007] The underwater topographic measurement device provided in this application adopts the following technical solution:

[0008] An underwater topographic measuring device, comprising:

[0009] Support frame;

[0010] A winding wheel with a measuring rope wound on the outside is rotatably connected to one end of the support frame;

[0011] The stepper motor is fixedly connected to one side of the support frame through a motor seat and is fixedly connected to the winding wheel;

[0012] A limit frame is fixedly connected to one side of the support frame;

[0013] The reciprocating screw rod is rotatably connected inside the limit frame and is frictionally driven by the winding wheel through the synchronous wheel and the synchronous belt;

[0014] The guide rail sleeve is limited in sliding motion outside the limit frame and is threadedly connected to the reciprocating screw rod;

[0015] The brush cylinder mounted on the outside of the measuring rope is rotatably connected to one side of the guide rail sleeve, and is meshed and adapted with the driven gear rotatably connected in the guide rail sleeve through the tooth groove opened on the outside, and the driven gear is meshed and adapted with the gear rail opened on the outside of the limit frame.

[0016] By adopting the above technical scheme, when a stepper motor is used to drive the winding wheel to release the measuring rope for detection, the reciprocating screw driven by friction with the winding wheel drives the guide sleeve to move circularly, and the released measuring rope is evenly routed. At the same time, during the reciprocating movement of the guide sleeve, the driven gear connected to its internal rotation engages with the limit frame, indirectly driving the brush cylinder to engage, so that the rotating brush cylinder can perform rotational cleaning on the released or wound measuring rope, thereby ensuring the neatness and beauty of the measuring rope when stored and used.

[0017] As an optional solution of the technical solution of the present application document, one end of the support frame is slidably connected to an extension frame, and the extension frame with a GPS mobile station installed externally is abutted and limited by fastening bolts.

[0018] By adopting the above technical solution and utilizing the telescopic connection between the extension frame and the support frame, the extension frame can be used more flexibly for laying out and detecting the measuring rope.

[0019] As an optional solution to the technical solution of the present application document, two pressure rollers are rotatably connected in a symmetrical structure within the extension frame, and the two pressure rollers are meshed and adapted for transmission through transmission gears fixedly connected on one side of the two pressure rollers, and one of the pressure rollers is frictionally driven by a reciprocating screw through a synchronous wheel and a synchronous belt.

[0020] By adopting the above technical solution, a reciprocating screw is used to drive a pressure roller to rotate in the same direction, so that two meshing transmission pressure rollers can release and hold the released or wound measuring rope, thereby ensuring the stability of the measuring rope when it is released or wound.

[0021] As an optional solution of the technical solution of the present application document, the pressure roller is fixedly connected to the outside with a silicone pressure wheel that can pull the measuring rope to tighten and release it.

[0022] By adopting the above technical solution, the moisture absorbed by the measuring rope can be squeezed out by using the silicone pressure wheel, thereby ensuring the reliability of the storage of the measuring rope.

[0023] As an optional solution to the technical solution of the present application document, a roller capable of reducing friction resistance is rotatably connected in a through groove opened on one side of the guide rail sleeve.

[0024] By adopting the above technical solution and utilizing the roller, the guide rail sleeve can be more sensitive when sliding outside the limit frame.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The present application utilizes a stepper motor to drive a winding wheel to release a measuring rope for detection use. The reciprocating screw rod that is frictionally driven by the winding wheel drives the guide rail sleeve to move circularly, and evenly lays out the released measuring rope. At the same time, during the reciprocating movement of the guide rail sleeve, the driven gear that is internally connected to the guide rail sleeve engages with the limit frame for transmission, and indirectly drives the brush cylinder to engage with the limit frame for transmission, so that the rotating brush cylinder performs rotational cleaning on the released or wound measuring rope, thereby ensuring the neatness and beauty of the measuring rope when it is stored and used.

[0027] 2. The present application utilizes a reciprocating screw to drive a pressure roller to rotate in the same direction, so that two meshing transmission pressure rollers can release and hold the released or wound measuring rope, thereby ensuring the stability of the measuring rope when it is released or wound. Under the action of the silicone pressure wheel, the moisture adsorbed by the measuring rope can be squeezed out, thereby ensuring the reliability of the storage of the measuring rope.

[0040] The underwater topographic surveying device utilizes a stepping motor 3 to drive a winding wheel 2 to release a measuring rope for detection use. The reciprocating screw rod 5 which is frictionally driven by the winding wheel 2 drives the guide rail sleeve 6 to move circularly, and evenly lays out the released measuring rope. Meanwhile, during the reciprocating movement of the guide rail sleeve 6, a driven gear 8 which is internally connected and rotates is meshed with a limit frame 4, and indirectly drives a brush barrel 7 to mesh, so that the rotating brush barrel 7 performs rotational cleaning on the released or wound measuring rope, thereby ensuring the neatness and beauty of the measuring rope when stored and used.

One end of the support frame 1 is slidably connected to an extension frame 11, and the extension frame 11 with a GPS mobile station installed outside is abutted and limited by fastening bolts. The pressure roller 12 is fixedly connected to the outside with a silicone pressure wheel 14 that can pull the measuring rope to tighten and release it.

[0042] The underwater topographic surveying device utilizes the telescopic connection between the extension frame 11 and the support frame 1, so that the extension frame 11 is more flexible in using the measuring rope for line laying and detection, and the reciprocating screw 5 drives a pressure roller 12 to rotate in the same direction, so that the two meshing transmission pressure rollers 12 can lay out and hold the released or wound measuring rope, thereby ensuring the stability of the measuring rope when it is laid out or wound, and the silicone pressure wheel 14 can squeeze the moisture absorbed by the measuring rope, thereby ensuring the reliability of the storage of the measuring rope.
