[0002] Underwater topography measurement is an indispensable part in the construction of water conservancy, waterways, ports and other projects. Through underwater topography measurement, we can understand the underwater topography of rivers, lakes, reservoirs, harbors and offshore waters, and provide accurate basic data for the planning, design and construction of water conservancy projects.

[0003] The patent with announcement number CN212030528U discloses an underwater measuring device for water conservancy construction; it includes a mounting frame, a mounting hole is provided on one side of the top outer wall of the mounting frame, a fixing seat is provided on the side of the top outer wall of the mounting frame near the mounting hole through bolts, and a glass cover is inserted inside the fixing seat and passes through the mounting frame through the mounting hole, a top cover is installed on the top outer wall of the fixing seat through bolts, and the top cover is inserted inside the glass cover, a driving motor is installed on one side of the top outer wall of the top cover through bolts, and a rotating shaft is installed on the output shaft of the driving motor through a coupling, and a base plate is keyed to the side outer wall of the rotating shaft near the bottom.

[0015] Preferably, a lighting lamp is provided on one side of the submersible camera body.

[0016] Preferably, a plurality of counterweights are provided on the lower end surface of the shell.

[0017] The beneficial effects of the present invention are as follows: 1. The underwater topographic measurement device with a submersible camera described in the present invention has a base placed at a suitable position on the hull. When the hull travels to the water area to be measured, the shell is placed on the water surface, and a motor is used to drive the rotating roller to rotate so that the rope can be unwound. The shell and the submersible camera body enter the water together. Through the submersible camera body, high-definition images or videos of the underwater topography can be transmitted to an external display device, thereby providing an accurate visual reference for underwater topographic measurement, which helps surveyors to draw underwater topographic maps more accurately. In addition, since the diving depth of the submersible camera body is controllable, the underwater area to be measured can be accurately selected according to actual needs, thereby obtaining more accurate topographic data.

[0018] 2. The underwater topographic surveying device with a submersible camera described in the present invention utilizes a surrounding scraping mechanism. When the staff finds that the picture taken by the submersible camera body is blocked by aquatic plants, the two scraping rings can be driven to descend at the same time, and the aquatic plants attached to the surface of the submersible camera body can be scraped off by the scraping rings to keep them away from the submersible camera body, thereby avoiding the situation where the aquatic plants are entangled or hung on the surface of the submersible camera body, affecting the normal shooting of the submersible camera body. Moreover, each time the scraping ring completes a scraping action and resets upward, the two adjusting rods can be driven to move in different directions at the same time, and the two scraping rings are away from the outer surface of the submersible camera body, so that the scraping rings and the submersible camera body are aligned. In the whole resetting process, since the scraper ring is far away from the diving camera body, even if there are aquatic plants entangled on the surface of the diving camera body, the scraper ring will not push the aquatic plants attached to the surface of the diving camera body upward, and the scraper ring will not hold the aquatic plants, and the aquatic plants will not continue to cover the diving camera body due to swinging, and the scraper ring will not be able to scrape them off. In addition, when the diving camera body is covered by aquatic plants growing on the bottom of the water, the scraper ring can be driven to fit the surface of the diving camera body after it drops to a position lower than the bottom of the diving camera body. The two scraper rings rotate in different directions at the same time, and the two scraper rings clamp the ends of the water plants. At this time, the water plants under the diving camera body will remain stable under the action of the two scraper rings, and will not reset to a state where they can cover the diving camera body, thereby avoiding the situation where the scraper ring scrapes the water plants covering the diving camera body downwards, and the water plants reset to a state where they can cover the diving camera body, thereby continuously covering the diving camera body. In addition, there is no need to change the height and orientation of the diving camera body, thereby ensuring that the diving camera body can continue to shoot underwater images at the original position, thereby improving the measurement accuracy. In addition, when the scraper ring no longer needs to clamp the water plants, the arc-shaped blade can be driven from The scraper ring extends out from the scraper ring to contact and squeeze the water plants, and at the same time, drives the arc-shaped blade to slide back and forth, and uses the serrations on its surface to cut the water plants entangled on the scraper ring, so that the water plants are separated from the scraper ring, thereby avoiding the water plants entangled on the scraper ring, which makes the two scraper rings difficult to separate. At the same time, it also avoids the scraper ring carrying the entangled water plants to be reset to the initial position, resulting in the water plants swinging on the scraper ring and covering the main body of the submersible camera. When the arc-shaped blade moves at the scraper ring, it forms a scraping with the groove of the scraper ring. Therefore, even if there is water plants attached to the surface of the arc-shaped blade, it will be scraped off when the arc-shaped blade is reset, thereby ensuring the continuous cutting effect of the arc-shaped blade.

[0019] 3. The underwater topographic surveying device with a submersible camera described in the present invention can illuminate the shooting area of ​​the submersible camera body with a lighting lamp, making the shot picture brighter and clearer, which is beneficial to improving the shooting quality.

[0020] 4. The underwater topographic measurement device with a submersible camera described in the present invention increases the weight of the shell by arranging multiple counterweights on the lower end surface of the shell, so that the submersible camera body can reach the target depth more quickly, thereby improving the shooting efficiency.

[0025] Please refer to Figure 1-Figure 9 The present invention provides a technical solution: an underwater topographic measurement device with a submersible camera, comprising a base 1, a support arm 28 is fixedly connected to the upper end surface of the base 1, a rotating roller 2 is rotatably arranged on the right side of the support arm 28, a supporting roller 5 is rotatably arranged on the left side of the support arm 28, a rope 4 is wound around the rotating roller 2, a lifting ring 7 is wound around the end of the rope 4, a housing 6 is fixedly connected to the lower end of the lifting ring 7, a submersible camera body 8 is arranged at the bottom of the housing 6, and a surrounding scraping mechanism is also arranged on the housing 6 to prevent aquatic plants from blocking the submersible camera body 8; The surrounding scraping mechanism includes a fixed plate 11 fixedly connected to one side of the lower end surface of the inner cavity of the shell 6, and a sliding rod 13 is fixedly connected to both ends of one side of the fixed plate 11.

[0026] In this embodiment, Figure 1 As shown, a motor 3 is fixedly connected to one side of the support arm 28, and an output end of the motor 3 is fixedly connected to the rotating roller 2.

[0027] Specifically, the base 1 is placed at a suitable position on the hull. When the hull travels to the water area to be measured, the shell 6 is placed on the water surface, and the motor 3 is used to drive the rotating roller 2 to rotate so that the rope 4 can be unwound. The shell 6 and the submersible camera body 8 enter the water together. Through the submersible camera body 8, high-definition images or videos of the underwater terrain can be transmitted to an external display device, thereby providing accurate visual reference for underwater terrain measurement, which helps surveyors to draw underwater terrain maps more accurately. In addition, since the diving depth of the submersible camera body 8 is controllable, the underwater area to be measured can be accurately selected according to actual needs, thereby obtaining more accurate terrain data.

[0028] In this embodiment, Figure 1-Figure 9 As shown, a threaded rod 12 is threadedly connected to one side of the lifting plate 16, and both ends of the threaded rod 12 are rotatably set on the fixed plate 11. A motor 2 10 is fixedly connected to one side of the upper end surface of the fixed plate 11, and the output end of the motor 2 10 is fixedly connected to one end of the threaded rod 12.

One end of the lifting plate 16 is fixedly connected with a motor three 15, and the output end of the motor three 15 is fixedly connected to one end of the bidirectional threaded rod 19.

[0030] One side of the lower end of the adjusting rod 9 is fixedly connected to a motor 4 21, and an output end of the motor 4 21 is fixedly connected to one side of the scraper ring 31.

[0031] A slider 22 is slidably connected to one side of the upper end surface of the inner cavity of the scraper ring 31, a sliding sleeve 24 is fixedly connected to the lower end of the slider 22, a sliding rod 25 is slidably connected to the inner side of the sliding sleeve 24, and an arc-shaped blade 20 is fixedly connected to the lower end surface of the sliding rod 25. A groove is provided on one side of the scraper ring 31, and the upper and lower surfaces of the arc-shaped blade 20 are both in contact with the inner side of the scraper ring 31, and the arc-shaped blade 20 can move in the groove of the scraper ring 31.

[0032] One side of the slider 22 is threadedly connected to a threaded rod 29 , both ends of the threaded rod 29 are rotatably arranged on the scraper ring 31 , one side of the inner cavity of the scraper ring 31 is fixedly connected to a motor 5 23 , and the output end of the motor 5 23 is fixedly connected to one end of the threaded rod 29 .

[0033] A motor 6 26 is fixedly connected to one side of the sleeve 24, and a gear 27 is fixedly connected to the output end of the motor 6 26. The gear 27 is rotatably set on the sleeve 24. A tooth block 30 is set on the inner ring of the arc blade 20, and the tooth block 30 and the gear 27 are meshed with each other. A plurality of saw teeth 32 are set on the outer ring of the arc blade 20.

[0034] Specifically, when the existing underwater measurement device is used, a camera is put into the river water to shoot underwater images with the camera. The images shot by the camera are sent to the remote control end through a transmitter so that the staff can understand the underwater situation. However, since aquatic plants such as water grass and duckweed grow in the river water, when the camera enters the water, these aquatic plants may float due to the water flow, thereby entangled or hung on the camera, thereby covering the camera and affecting the normal shooting of the camera. Therefore, in order to solve the above problems, when the present embodiment is in use, the electric control equipment in the present embodiment adopts a waterproof design and can work for a long time underwater; the two scraper rings 31 in the initial state are at the upper end of the diving camera body 8, which will not affect the shooting of the diving camera body 8. When the staff finds that the picture taken by the diving camera body 8 is blocked by aquatic plants, the motor 2 10 can be used to drive the threaded rod 12 to rotate, so that the lifting plate 16 moves from top to bottom, and the two scraper rings 31 can be dropped at the same time, and the scraper rings 31 can be used to scrape off the aquatic plants attached to the surface of the diving camera body 8, so that they are away from the diving camera body 8, thereby avoiding the situation where the aquatic plants are entangled or hung on the surface of the diving camera body 8, affecting the normal shooting of the diving camera body 8, and every time the scraper ring 31 completes a scraping action and resets upward, if there are aquatic plants attached to the surface of the diving camera body 8 at this time, then, if the scraper ring 31 is reset according to the original path, it will cause the scraper ring 31 to push the aquatic plants attached to the surface of the diving camera body 8 upward, and the water The aquatic plants will be held by the scraper ring 31, and the held aquatic plants may continue to cover the submersible camera body 8 due to the swing, and because they are above the scraper ring 31, the scraper ring 31 cannot scrape them off. Therefore, in order to avoid this situation, when the scraper ring 31 completes a scraping action and resets upward, the motor 3 15 can be used to drive the bidirectional threaded rod 19 to rotate, so that the two adjustment rods 9 move in different directions at the same time, and the two scraper rings 31 are away from the outer surface of the submersible camera body 8. A gap is generated between the scraper ring 31 and the surface of the submersible camera body 8. When the scraper ring 31 rises to the initial height, the scraper ring 31 is driven to fit the surface of the submersible camera body 8. During the entire reset process, since the scraper ring 31 is away from the submersible camera body 8, even if there are aquatic plants entangled on the surface of the submersible camera body 8 again, the scraper ring 31 will not push the aquatic plants attached to the surface of the submersible camera body 8 upward, and the scraper ring 31 will not hold the aquatic plants, and the aquatic plants will continue to cover the submersible camera body 8 due to the swing, and the scraper ring 31 will not scrape them off. For some aquatic plants floating in the water, the above method can be used to easily keep them away from the submersible camera body 8. However, when the submersible camera body 8 is just covered by the aquatic plants growing on the bottom of the water, since the roots of the aquatic plants are in the underwater soil, even if the scraper ring 31 pushes the aquatic plants downward, the aquatic plants are easy to reset after bending, thereby continuing to cover the submersible camera body 8. In order to avoid this situation, when the height and orientation of the submersible camera body 8 are changed, it will deviate from the original measurement position, affecting the measurement accuracy. Therefore, in order to avoid this situation, when the submersible camera body 8 is just covered by the aquatic plants growing on the bottom of the water, the scraper ring 31 can be lowered to a position below the bottom of the submersible camera body 8, and two The motor 21 drives the two scraper rings 31 to rotate in different directions at the same time, so that the two scraper rings 31 fit together. When the two scraper rings 31 fit together, the ends of the water plants can be clamped. At this time, the water plants below the diving camera body 8 will remain stable under the action of the two scraper rings 31 and will not be reset to a state where they can cover the diving camera body 8. This avoids the situation where the scraper rings 31 scrape the water plants covering the diving camera body 8 downwards, and the water plants are reset to a state where they can cover the diving camera body 8, thereby continuously covering the diving camera body 8. In addition, there is no need to change the height and orientation of the diving camera body 8, which ensures that the diving camera body 8 can continue to shoot underwater images at the original position, thereby improving the measurement accuracy. Since the water plants are clamped by the two scraper rings 31, the water plants are easily entangled on the scraper rings 31 due to swinging. When aquatic plants are entangled on the scraper rings 31, it is not only not conducive to separating the two scraper rings 31, but also the scraper rings 31 may carry the entangled water plants to return to the initial position, resulting in the water plants swinging on the scraper rings 31 and covering the diving camera body 8, affecting the subsequent shooting work. Therefore, in order to avoid this problem, when the scraper rings 31 no longer need to clamp the water plants, the motor five 23 can be used to drive the threaded rod two 29 to rotate, so that the slider 22 slides, and the arc-shaped blade 20 extends from the scraper ring 31 to contact the water plants and squeeze the water plants. At the same time, the motor six 26 is used to drive the gear 27 to rotate forwards and backwards, so that the sliding sleeve 24 and the slide bar 25, the arc-shaped blade 20 slides back and forth, and the serrations 32 on its surface are used to cut the water plants entangled on the scraper ring 31, so that the water plants are separated from the scraper ring 31, thereby avoiding the situation that the two scraper rings 31 are difficult to separate due to the water plants entangled on the scraper ring 31. At the same time, it also avoids the scraper ring 31 carrying the entangled water plants to reset to the initial position, causing the water plants to swing on the scraper ring 31 and cover the diving camera body 8. At the same time, because the arc-shaped blade 20 forms a scraping with the groove of the scraper ring 31 when moving at the scraper ring 31, even if there is water plants attached to the surface of the arc-shaped blade 20, they will be scraped off when the arc-shaped blade 20 is reset, so the cutting effect of the arc-shaped blade 20 can be continuously guaranteed.

[0035] In this embodiment, Figure 5 As shown, a lighting lamp 17 is provided on one side of the diving camera body 8.

[0036] Specifically, the lighting lamp 17 can be used to illuminate the shooting area of ​​the diving camera body 8, making the captured image brighter and clearer, which is beneficial to improving the shooting quality.

[0037] In this embodiment, Figure 5 As shown, a plurality of counterweights 14 are provided on the lower end surface of the housing 6 .

[0038] Specifically, by arranging a plurality of counterweight blocks 14 on the lower end surface of the shell 6, the weight of the shell 6 is increased, so that the submersible camera body 8 can reach the target depth faster, thereby improving the shooting efficiency.

[0039] Working principle: place the base 1 at a suitable position on the hull. When the hull travels to the water area to be measured, place the shell 6 on the water surface, and use the motor 3 to drive the rotating roller 2 to rotate, so that the rope 4 can be unwound, and the shell 6 and the diving camera body 8 enter the water together. Through the diving camera body 8, high-definition images or videos of the underwater terrain can be transmitted to the external display device, thereby providing an accurate visual reference for underwater terrain measurement, which helps surveyors to draw underwater terrain maps more accurately. In addition, since the diving depth of the diving camera body 8 is controllable, the underwater area to be measured can be accurately selected according to actual needs, so as to obtain more accurate terrain data. By arranging a plurality of counterweight blocks 14 on the lower end face of the shell 6, the weight of the shell 6 is increased, so that The submersible camera body 8 can reach the target depth faster, thereby improving the shooting efficiency. The lighting lamp 17 can be used to illuminate the shooting area of ​​the submersible camera body 8, making the shot picture brighter and clearer, which is conducive to improving the shooting quality. The two scraping rings 31 in the initial state are at the upper end of the submersible camera body 8 and will not affect the shooting of the submersible camera body 8. When the staff finds that the picture shot by the submersible camera body 8 is blocked by aquatic plants, the motor 2 10 can be used to drive the threaded rod 1 12 to rotate, so that the lifting plate 16 moves from top to bottom, so that the two scraping rings 31 can be lowered at the same time, and the scraping rings 31 can be used to scrape off the aquatic plants attached to the surface of the submersible camera body 8, so that they are away from the submersible camera body 8, thereby avoiding This avoids the situation where aquatic plants are entangled or hung on the surface of the submersible camera body 8, affecting the normal shooting of the submersible camera body 8. Moreover, whenever the scraper ring 31 completes a scraping action and resets upward, if there are aquatic plants attached to the surface of the submersible camera body 8 at this time, then if the scraper ring 31 resets according to the original path, the scraper ring 31 will push the aquatic plants attached to the surface of the submersible camera body 8 upward, and the aquatic plants will be supported by the scraper ring 31. The supported aquatic plants may continue to cover the submersible camera body 8 due to swinging, and since they are above the scraper ring 31, the scraper ring 31 cannot scrape them off. Therefore, in order to avoid this situation, when the scraper ring 31 completes a scraping action and resets upward, the motor 33 can be used to 15 drives the bidirectional threaded rod 19 to rotate, so that the two adjustment rods 9 move in different directions at the same time, and the two scraper rings 31 are away from the outer surface of the submersible camera body 8, and a gap is formed between the scraper ring 31 and the surface of the submersible camera body 8. When the scraper ring 31 rises to the initial height, the scraper ring 31 is driven to fit the surface of the submersible camera body 8. During the entire resetting process, since the scraper ring 31 is away from the submersible camera body 8, even if there are aquatic plants entangled on the surface of the submersible camera body 8, the scraper ring 31 will not push the aquatic plants attached to the surface of the submersible camera body 8 upward, and the scraper ring 31 will not support the aquatic plants, and the aquatic plants will not continue to cover the submersible camera body 8 due to swinging, and the scraper ring 31 will not be able to scrape them off;For some aquatic plants floating in the water, the above method can easily keep them away from the submersible camera body 8. However, when the submersible camera body 8 is just covered by the water plants growing on the bottom of the water, since the roots of the water plants are in the underwater soil, even if the scraper ring 31 pushes the water plants downward, the water plants are easy to reset after bending, thereby continuing to cover the submersible camera body 8. In order to avoid this situation, when the height and orientation of the submersible camera body 8 are changed, it will deviate from the original measurement position, affecting the measurement accuracy. Therefore, in order to avoid this situation, when the submersible camera body 8 is just covered by the water plants growing on the bottom of the water, the scraper ring 31 can be lowered to a position below the bottom of the submersible camera body 8, and the two motors 42 can be used. 1 drives the two scraping rings 31 to rotate in different directions at the same time, so that the two scraping rings 31 fit together. When the two scraping rings 31 fit together, the ends of the water plants can be clamped. At this time, the water plants under the diving camera body 8 will remain stable under the action of the two scraping rings 31 and will not be reset to a state where they can cover the diving camera body 8, thereby avoiding the situation where the water plants covering the diving camera body 8 are reset to a state where they can cover the diving camera body 8 after the scraping rings 31 scrape the water plants covering the diving camera body 8 downward, and then continue to cover the diving camera body 8. In addition, there is no need to change the height and orientation of the diving camera body 8, which ensures that the diving camera body 8 can continue to shoot underwater images at the original position, thereby improving the measurement accuracy. The two scraper rings 31 are clamped, so the water plants are easily entangled on the scraper rings 31 due to swinging. When aquatic plants are entangled on the scraper rings 31, it is not only not conducive to separating the two scraper rings 31, but also the scraper rings 31 may carry the entangled water plants to reset to the initial position, resulting in the water plants swinging on the scraper rings 31 and covering the diving camera body 8, affecting the subsequent shooting work. Therefore, in order to avoid this problem, when the scraper rings 31 no longer need to clamp the water plants, the motor five 23 can be used to drive the threaded rod two 29 to rotate, so that the slider 22 slides, and the arc blade 20 extends from the scraper ring 31 to contact the water plants and squeeze the water plants. At the same time, the motor six 26 is used to drive the gear 27 to rotate forwards and backwards, so that the sliding sleeve 24 and the sliding sleeve 24 can be moved back and forth. Under the action of the second rod 25, the arc blade 20 slides back and forth, and the saw teeth 32 on its surface are used to cut the water grass wrapped around the scraper ring 31, so that the water grass is separated from the scraper ring 31, thereby avoiding the situation that the two scraper rings 31 are difficult to separate due to the water grass wrapped around the scraper ring 31. At the same time, it also avoids the scraper ring 31 carrying the wrapped water grass to reset to the initial position, and the water grass swings on the scraper ring 31 and covers the diving camera body 8. At the same time, since the arc blade 20 forms a scraping with the groove of the scraper ring 31 when moving at the scraper ring 31, even if there is water grass attached to the surface of the arc blade 20, it will be scraped off when the arc blade 20 is reset, so the cutting effect of the arc blade 20 can be continuously guaranteed. ;
