Description

Technical Field

[0001] The present invention relates to the technical field of marine detection devices, and particularly to an underwater terrain detection device. Background Art

[0002] The shipborne underwater terrain detection device is used to measure the planar position and elevation of waters such as rivers, lakes, reservoirs, and harbors for the surveying and mapping work of drawing underwater topographic maps. Most of the existing shipborne underwater terrain detection devices put the detector into the water by unreeling a rope and conduct detection while moving with the ship. For example, CN202310698893.0 discloses an underwater terrain detection device and its detection method. An underwater terrain detection device includes a floating hull and an extension structure under the floating hull. The extension structure includes a positioning base, a vertical groove base, a limiting roller, a support frame, and a detector. A support frame is installed inside the floating hull, an extension tube is wound inside the support frame, and limiting rollers are symmetrically installed below the support frame. Through the cooperation of the first centrifugal ring and the second centrifugal ring, the first centrifugal ring and the second centrifugal ring rotate in opposite directions, and the angular momentum conservation force achieved by the two is used to maintain the stability of the device when it is on the water surface, so that the device can be free from the influence of water surface ripples and always be in a stable navigation state, minimizing the impact on the detection equipment during detection, thereby increasing the stability of the device on the water surface.

[0003] However, for the existing underwater terrain detection devices, during the process of moving with the ship, due to the action of water buoyancy and other factors, when the terrain detection device put into the water through a rope moves with the ship, its height will change, resulting in errors in the detection results; while using a straight rod structure to put the detection device into the water, it is difficult to store, and the length of the fixed rod cannot meet the detection requirements. Summary of the Invention

[0004] An embodiment of the present disclosure relates to an underwater terrain detection device. The electric control telescopic rod is inserted into the round hole on the connecting bar. With the push of the cylinder, the lower block is driven to be clamped into the chute in the upper connecting bar. With the addition of the inertial effect of the redirecting motor, the connecting bar is toggled to rotate, and then clamped into the inner card slot in the upper connecting bar, so that the connecting bar can be put into the water in the form of a straight rod, and the detection result is more accurate.

[0006] In at least some embodiments, a transmission wheel is coaxially and fixedly connected to the outer end of the threaded rod, a moving plate is meshed with the threaded rod, two round rods are welded to the bottom of the moving plate, a dial plate is fixedly welded to the end of the round rod, the dial plate fits on the outer side surface of the first connecting strip, and the bottom surface of the dial plate fits on the outer surface of the winding wheel.

[0007] In at least some embodiments, a clamping block is welded to the top end of the connecting strip, a protruding rectangular block is welded to the outside of the clamping block, an arc-shaped chute is opened at the bottom of the connecting strip, an inner card slot is opened at the inner end of the chute, a receiving groove is opened inside the clamping block, and a connecting rod is clamped below the inside of the connecting strip. A limiting plate is welded to the top end of the connecting rod, the bottom of the connecting rod is connected to the clamping block of the next connecting strip through a chain, and an underwater terrain detector is fixedly connected to the bottom of the lowermost connecting strip. After the push rod of the flagpole pushes to lift the lower connecting strip, the clamping block of the connecting strip can be disengaged from the inner card slot in the previous connecting strip. After the connecting strip is toggled by the redirecting component, the clamping block rotates to the outer end of the chute, and the connecting strip will fall downward under the action of gravity, so as to disengage from the chute in the previous connecting strip. Through the chain, the two connecting strips can be bent, so as to be wound on the winding wheel.

[0008] In at least some embodiments, the winding driving component further includes a card shaft, the card shaft is fixedly connected to the driving shaft of the winding motor, the card shaft is clamped inside the winding wheel, and a protruding rectangular plate is welded to the outside of the card shaft. The protruding rectangular plate can increase the clamping area with the winding wheel and improve the synchronous rotation stability during winding or unwinding.

[0009] In at least some embodiments, the redirecting component further includes a rotating plate and an electric control telescopic rod. An outer card slot is opened on the outer wall of the redirecting motor, a card strip is clamped inside the outer card slot, the driving shaft of the redirecting motor is coaxially connected to the rotating plate, and the electric control telescopic rod is installed on the inner end face of the rotating plate. When the electric control telescopic rod is at the highest position, the electric control telescopic rod corresponds to the position of the round hole opened on the connecting strip.

The push rod of the cylinder is vertically limited by the rectangular block and the limiting block, and the clamping strip can limit the redirecting motor in the up and down directions.

[0012] The present invention provides an underwater terrain detection device, which has the following beneficial effects: When the present invention is in use, the electric control telescopic rod is inserted into the circular hole on the connecting strip. Driven by the cylinder, the lower clamping block is driven to be clamped into the sliding groove in the upper connecting strip. Driven by the rotation of the redirecting motor, the electric control telescopic rod rotates, and with the action of inertia, the connecting strip is driven to rotate, so as to be clamped with the inner clamping groove in the upper connecting strip, and the connection during the unwinding of the connecting strip can be completed.

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0019] Embodiment: Please refer to the attached Figure 1 to the attached Figure 9 : The present invention provides an underwater terrain detection device, comprising: a fixed seat 1; a connecting plate 101 is welded to the side of the fixed seat 1, and a winding driving component 2 is installed on the top of the fixed seat 1; the winding driving component 2 includes a winding motor 21, a threaded rod 3 is connected to the driving shaft of the winding motor 21 through a transmission belt 2101, and a winding wheel 7 is installed on the driving shaft of the winding motor 21; a connecting strip 4 is fixedly connected to the outer surface of the winding wheel 7, and the threaded rod 3 is rotationally clamped in the baffles on both sides of the winding wheel 7; a cylinder 5 is installed on the outside of the connecting plate 101; the top of the push rod 501 of the cylinder 5 is installed with a redirecting component 6; the redirecting component 6 includes a redirecting motor 61, and the redirecting motor 61 is clamped in the connecting plate 101.

[0020] In the embodiment of the present disclosure, as shown in the attached Figure 3 figure, the push rod 501 of the cylinder 5 penetrates through a rectangular block with a circular hole opened outside the connecting plate 101, and the top of the push rod 501 is fixedly connected with a semi-cover shell, and the redirecting motor 61 is fixedly connected inside the semi-cover shell. After starting the cylinder 5 through an external remote control terminal, the redirecting component 6 is driven to move up and down through the push rod 501, so that the clamping block 401 of the connecting strip 4 can be pushed to disengage from the previous connecting strip 4, thereby completing the disassembly of the connecting strip 4 during winding.

[0021] In the embodiment of the present disclosure, as shown in the attached Figure 5 figure, the winding driving component 2 further includes a clamping shaft 22, the clamping shaft 22 is fixedly connected to the driving shaft of the winding motor 21, the clamping shaft 22 is clamped inside the winding wheel 7, and a protruding rectangular plate is welded to the outside of the clamping shaft 22. The clamping area with the winding wheel 7 can be increased through the protruding rectangular plate, the synchronous rotation stability during winding or unwinding can be improved, and at the same time, the synchronous rotation of the winding wheel 7 and the winding motor 21 is ensured, so as to wind or unwind the connecting strip 4.

[0022] In the embodiment of the present disclosure, as shown in the attached Figure 3 figure, the redirecting component 6 further includes a rotating plate 62 and an electric control telescopic rod 63. An external card slot 6101 is opened on the outer wall of the redirecting motor 61, a card strip 1013 is clamped inside the external card slot 6101, the driving shaft of the redirecting motor 61 is coaxially connected to the rotating plate 62, and the electric control telescopic rod 63 is installed on the inner end surface of the rotating plate 62. When the electric control telescopic rod 63 is at the highest position, the electric control telescopic rod 63 corresponds to the position of the circular hole opened on the connecting strip 4. After the electric control telescopic rod 63 rotates to the highest point along with the rotating plate 62, the electric control telescopic rod 63 is started to extend through a set program and inserted into the circular hole on the connecting strip 4. Along with the pushing of the cylinder 5, the clamping block 401 below is driven to disengage from the inner card slot 403 in the upper connecting strip 4. Along with the rotation of the redirecting motor 61, the electric control telescopic rod 63 is driven to rotate, and the connecting strip 4 is toggled to rotate by the action of inertia, so as to disengage from the sliding slot 402 in the upper connecting strip 4, completing the automatic disassembly between the two connecting strips 4 and smoothly winding.

[0023] In the embodiments of the present disclosure, as shown in the appended Figure 4 drawing and the appended Figure 5 drawing, a driving wheel 301 is coaxially and fixedly connected to the outer end of the threaded rod 3. A moving plate 302 is meshed with the threaded rod 3. Two round rods are welded to the bottom of the moving plate 302. A shifting plate 3021 is fixedly welded to the end of the round rod. The shifting plate 3021 is attached to the outer side surface of the first connecting strip 4, and the bottom surface of the shifting plate 3021 is attached to the outer surface of the winding wheel 7. When the winding motor 21 rotates, the driving wheel 301 is driven to rotate through the transmission belt 2101, the threaded rod 3 is coaxially driven to rotate, and the moving plate 302 is driven to move through meshing. However, due to the restriction of the surface of the winding wheel 7, the shifting plate 3021 cannot rotate, so the moving plate 302 is converted into a movement, and the shifting plate 3021 is synchronously driven to move, causing the connecting strip 4 to shift, and thus winding can be performed.

[0024] In the embodiments of the present disclosure, as shown in the appended Figure 9 drawing, the top of the fixed seat 1 is a pallet structure arranged at equal intervals. An installation plate 1011 is fixedly welded to the outside of the connecting plate 101. A limiting block 1012 is fixedly connected to the outside of the connecting plate 101 through a bolt assembly. A vertical sliding groove is opened above the limiting block 1012 inside the connecting plate 101. A clamping strip 1013 is fixedly welded to the inner wall of the sliding groove. A rectangular block with a circular hole is fixedly connected to the outside of the connecting plate 101. The push rod 501 of the air cylinder 5 is vertically limited by the rectangular block and the limiting block 1012. The clamping strip 1013 can limit the reversing motor 61 in the up and down directions, ensuring that the connecting strip 4 can be disassembled during the winding process. The fixed seat 1 is beneficial to the heat dissipation of the winding motor 21 by means of the pallets with intervals.

[0025] In the embodiments of the present disclosure, as shown in the appended Figure 6 drawing, the appended Figure 7 drawing and the appended Figure 8As shown, a clamping block 401 is welded to the top end of the connecting bar 4. A protruding rectangular block is welded to the outside of the clamping block 401. An arc-shaped sliding groove 402 is formed at the bottom of the connecting bar 4. An inner clamping groove 403 is formed at the inner end of the sliding groove 402. A storage groove 405 is formed inside the clamping block 401. A connecting rod 404 is clamped below the inside of the connecting bar 4. A limiting plate 4041 is welded to the top end of the connecting rod 404. The bottom of the connecting rod 404 is connected to the clamping block 401 of the next connecting bar 4 through a chain. The bottom of the lowermost connecting bar 4 is fixedly connected to an underwater terrain detector. After the lower connecting bar 4 is lifted by pushing the push rod 501 of the air cylinder 5, the clamping block 401 of the connecting bar 4 can be separated from the inner clamping groove 403 in the previous connecting bar 4. After the connecting bar 4 is toggled by the redirecting assembly 6, the clamping block 401 rotates to the outer end of the sliding groove 402. Under the action of gravity, the connecting bar 4 will fall downward, so as to separate from the sliding groove 402 in the previous connecting bar 4. The two connecting bars 4 can be bent through the chain, so as to be wound onto the winding wheel 7. When the connecting rod 404 moves downward, the downward movement of the connecting rod 404 is limited by the limiting plate 4041 to prevent the connecting rod 404 from falling off. When the connecting bar 4 is clamped together to form a straight rod by using the storage groove 405, the connecting rod 404 in the previous connecting bar 4 can be stored, so as to ensure that the connecting bar 4 can put the detector into the water in the state of a straight rod for detection.

[0026] In the embodiment of the present disclosure, as shown in the appendix Figure 4 As shown, a synchronous clamping groove 701 is formed on the inner wall of the winding wheel 7. A protruding rectangular plate welded to the outside of the clamping shaft 22 is clamped inside the synchronous clamping groove 701. Through the synchronous clamping groove 701, the winding wheel 7 can rotate synchronously with the winding motor 21, so as to wind or unwind, and complete the putting in or taking out of the underwater terrain detector.

[0027] The working principle of this embodiment: After the electric control telescopic rod 63 rotates to the highest point with the rotating plate 62, the electric control telescopic rod 63 is started to extend through a set program and inserted into the round hole on the connecting bar 4. With the pushing of the air cylinder 5, the clamping block 401 below is driven to separate from the inner clamping groove 403 in the upper connecting bar 4. With the rotation of the redirecting motor 61, the electric control telescopic rod 63 is driven to rotate. With the action of inertia, the connecting bar 4 is toggled to rotate, so as to separate from the sliding groove 402 in the upper connecting bar 4, and the clamping block 401 rotates to the outer end of the sliding groove 402. Under the action of gravity, the connecting bar 4 will fall downward, so as to separate from the sliding groove 402 in the previous connecting bar 4. The two connecting bars 4 can be bent through the chain. By operating in the reverse direction, the connection during the unwinding of the connecting bar 4 can be completed, so that when the underwater terrain detector is put into the water, the connecting bar 4 can be put into the water in the form of a straight rod and perform detection as the hull moves; After the winding motor 21 rotates, it drives the driving wheel 301 to rotate through the transmission belt 2101, coaxially drives the threaded rod 3 to rotate, drives the moving plate 302 to rotate through meshing, synchronously drives the shifting plate 3021 to move, so that the connecting bar 4 is offset, and then winding can be carried out.
