Description

Technical Field

[0001] This invention belongs to the field of geographic surveying and mapping technology, specifically a high-resolution remote sensing surveying and mapping device and its usage method. Background Technology

[0002] Remote sensing mapping technology, as an important component of modern surveying and mapping, is widely used in various fields such as land resource surveys, urban planning, environmental monitoring, agricultural management, and disaster early warning. With technological advancements and increasing societal demands, the accuracy, resolution, and data processing capabilities of remote sensing mapping equipment are constantly improving. However, numerous challenges remain in remote sensing mapping of underwater topography.

[0003] Chinese patent application CN118347478B discloses a method for underwater topographic mapping of irregular water bodies. The key technical points of the method are: Step 1: Using GNSS-RTK technology to measure the outer boundary of the irregular water body, generating remote sensing image data, and obtaining the outer boundary and first boundary plan view of the irregular water body; Step 2: Inputting the outer boundary data of the irregular water body into an unmanned surface vessel (USV) remote control system, using the outer boundary data to design a route for aerial surveying of the irregular water body, and achieving accurate underwater topographic measurement and data acquisition through the USV remote control system; Step 3: Generating a topographic map of the irregular water body.

[0004] When the aforementioned technologies utilize remote sensing equipment mounted on survey vessels to detect underwater geographic information, the remote sensing equipment typically lacks adequate protection measures and is easily impacted by undercurrents, coastal areas, and reefs. Furthermore, the natural aquatic environment is complex, with a large amount of floating debris such as garbage, vegetation, buoys, and low-density rocks on the water surface. These are difficult for the survey vessel to avoid in time, leading to the easy collision of floating debris with the remote sensing equipment, which reduces the accuracy of the equipment's mapping and its service life.

[0005] Therefore, the present invention provides a high-resolution remote sensing mapping device and a method for using the same. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a high-resolution remote sensing mapping device, comprising a mapping vessel and a high-resolution remote sensing component; the high-resolution remote sensing component is disposed on the side of the mapping vessel and is used to measure underwater topography;

[0008] A connection protection component is provided between the surveying vessel and the high-resolution remote sensing component; the connection protection component is used to buffer and protect the high-resolution remote sensing component.

[0009] The connection and protection assembly includes a pair of fixed seats; the surfaces of the fixed seats are connected to movable seats via hinges and torsion springs; a reinforcing rod is fixedly connected between the movable seats; a support arm is hinged to the surface of one of the movable seats; a damper is hinged between the support arm and the other movable seat; the angle between the support arm and the surveying vessel is less than 90°; and the high-resolution remote sensing component is fixedly connected to the end of the support arm.

[0010] Preferably, the high-resolution remote sensing component includes a float, and the float has a ring-shaped design; a remote sensor is disposed inside the float; a probe is disposed at the bottom of the remote sensor; and a cover is fixedly connected to the top of the float at the position above the remote sensor.

[0011] Preferably, a pair of drive rollers are rotatably connected inside the support arm; one of the drive rollers is connected to a motor; an elastic belt is sleeved between the drive rollers; and a set of inclined peeling teeth are evenly distributed on the outer side of the elastic belt.

[0012] Preferably, the side of the float away from the surveying vessel has an installation groove; a guide wheel is rotatably connected inside the installation groove; a set of paddles are evenly distributed on the surface of the guide wheel, and the ends of the paddles extend into and out of the float through the installation groove; a flexible strip is fixedly connected to the upper side of the paddles.

[0013] Preferably, an electromagnet and a sliding groove are respectively provided on the upper and lower sides of the mounting groove; a stop post is slidably connected inside the sliding groove; the electromagnet attracts the stop post when energized; the top of the stop post is tapered, and a spring is fixedly connected between the bottom of the stop post and the sliding groove.

[0014] Preferably, an annular sleeve is fixedly connected inside the float, and the annular sleeve is disposed on the outside of the remote sensor and fits therewith; a cooling cavity is provided inside the annular sleeve; a water inlet groove and a water outlet groove are respectively opened on the front and rear sides of the float; the water inlet groove and the water outlet groove are both connected to the inside of the annular sleeve.

[0015] Preferably, both the inlet tank and the outlet tank are equipped with filter screens.

[0016] Preferably, the annular sleeve is provided with a baffle plate inside; the baffle plate has a wave-shaped design and the whole is annular; a group of flow holes are evenly distributed on the surface of the baffle plate.

[0017] A method of using a high-resolution remote sensing mapping device, applicable to the aforementioned high-resolution remote sensing mapping device, includes the following steps:

[0018] A1. The underwater topography is measured by carrying high-resolution remote sensing components on a surveying vessel. When the support arm or remote sensing components are impacted, the support arm moves closer to the surveying vessel and swings, and the damper immediately contracts and absorbs the impact energy.

[0019] A2. The motor drives the drive roller and elastic belt to rotate, and the peeling teeth located on the outside of the support arm move towards the floating body, gradually pushing the floating objects on the side of the support arm backward and separating them from the support arm.

[0020] A3. The water flow that sweeps across the outside of the mounting slot drives the lever and guide wheel to rotate. When the guide wheel rotates into the inside of the float, its flexible strip sweeps across the underside of the probe and wipes away the dirt on the probe surface.

[0021] A4. After the probe is cleaned, the electromagnet is energized and attracts the baffle column, which then moves upward into the mounting slot, braking the lever so that it cannot rotate with the water flow.

[0022] A5. When the float moves in the water, the external water flow enters the cooling chamber of the annular sleeve through the water inlet groove, and then the water flow disperses and flows to both sides inside the annular sleeve.

[0023] A6. Part of the water continues to flow horizontally through the diversion holes of the baffle plate, while the other part of the water flows up and down along the surface of the baffle plate. These two parts of water collide and disperse with each other during the flow process, and finally converge into the outlet tank and flow outward.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. The high-resolution remote sensing mapping equipment and its usage method described in this invention improves the remote sensing component's resistance to obstacles in water by setting a connecting protective component between the mapping vessel and the high-resolution remote sensing component, utilizing the triangular stable structure formed by the reinforcing rod, support arm, and damper. When the support arm or remote sensing component is impacted, the support arm moves closer to the mapping vessel and swings, further reducing the angle between the support arm and the reinforcing rod. The damper then contracts and absorbs the impact energy, playing a buffering role, enhancing the protection effect on the remote sensing component, and improving the detection accuracy and service life of the remote sensing mapping equipment.

[0026] 2. The high-resolution remote sensing mapping device and its usage method described in this invention, when a floating object hits the side of the support arm and is difficult to detach, especially some relatively soft floating objects, such as aquatic plants, branches, fabrics, rubber products, etc., can be driven by a motor to rotate the drive roller and elastic belt. This causes the peeling teeth located on the outside of the support arm to move towards the floating body, gradually pushing the floating object on the side of the support arm backward and separating it from the support arm, preventing the floating object from compressing the support arm for a long time and increasing the driving resistance.

[0027] 3. The high-resolution remote sensing mapping device and its usage method described in this invention, by setting guide wheels, levers, and flexible strips, allows the water flow passing over the outside of the mounting groove to drive the levers and guide wheels to rotate as the float moves with the mapping vessel. When the guide wheels rotate into the inside of the float, their flexible strips can sweep across the underside of the probe and wipe away dirt from the probe surface, maintaining the high transparency of the probe and preventing dirt from affecting the transmission and reception of measurement signals.

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0040] like Figures 1 to 8 As shown, the high-resolution remote sensing mapping device of the present invention includes a mapping vessel 1 and a high-resolution remote sensing component; the high-resolution remote sensing component is disposed on the side of the mapping vessel 1 and is used to measure underwater topography.

[0041] The surveying vessel 1 can be a manned vessel or an unmanned remote-controlled vessel; the high-resolution remote sensing component has a built-in remote sensor 8, which uses a laser scanner (LiDAR) or a multibeam sonar. The laser scanner can achieve millimeter-level accuracy, and the multibeam sonar can achieve centimeter-level accuracy, thus realizing high-resolution underwater geographic model surveying.

[0042] A connection protection component is provided between the surveying vessel 1 and the high-resolution remote sensing component; the connection protection component is used to buffer and protect the high-resolution remote sensing component.

[0043] The connection and protection assembly includes a pair of fixed seats 2; the surfaces of the fixed seats 2 are connected to movable seats 3 by hinges and torsion springs; a reinforcing rod 4 is fixedly connected between the movable seats 3; a support arm 5 is hinged to the surface of one of the movable seats 3; a damper 6 is hinged between the support arm 5 and the other movable seat 3; the angle between the support arm 5 and the surveying vessel 1 is less than 90°, preferably around 30°; the high-resolution remote sensing component is fixedly connected to the end of the support arm 5.

[0044] When existing technologies utilize survey vessels to carry remote sensing equipment to detect underwater geographic information, the remote sensing equipment usually lacks certain protective measures and is easily impacted by undercurrents, coastal areas, and reefs. Furthermore, the natural aquatic environment is complex, with a large amount of floating debris such as garbage, vegetation, buoys, and low-density rocks on the water surface. Survey vessels cannot avoid these debris in time, which can easily cause the floating debris to collide with the remote sensing equipment, reducing the accuracy of the equipment's mapping and its service life.

[0045] This invention improves the remote sensing component's resistance to obstacles in the water by setting up a connecting protective assembly between the surveying vessel 1 and the high-resolution remote sensing component. The triangular stability structure formed by the reinforcing rod 4, the support arm 5, and the damper 6 enhances the remote sensing component's ability to resist obstacles in the water. Under the action of water surface fluctuations, the remote sensing component and the connecting protective assembly can swing up and down through the hinge. When the support arm 5 or the remote sensing component is impacted, the support arm 5 moves horizontally towards the surveying vessel 1 and swings, further reducing the angle between the support arm 5 and the reinforcing rod 4. The damper 6 then contracts and absorbs the impact energy, playing a buffering role and enhancing the protection of the remote sensing component. This improves the detection accuracy and service life of the remote sensing surveying equipment.

[0046] The high-resolution remote sensing component includes a float 7, which is a ring-shaped design; a remote sensor 8 is installed inside the float 7; a probe 9 is installed at the bottom of the remote sensor 8; and a cover 10 is fixedly connected to the top of the float 7 at the upper side of the remote sensor 8.

[0047] Since the remote sensor 8 is installed inside the float 7, which floats on the water surface, it can further support the remote sensor 8, increase the load-bearing limit of the connecting protective components, and the annular structure of the float 7 covers the probe 9 of the remote sensor 8, which can block external light. As a result, the probe 9 is less affected by water surface reflection when measuring downwards, reducing interference to the remote sensor 8 and further improving the mapping accuracy.

[0048] In another embodiment of the present invention, a pair of drive rollers 11 are rotatably connected inside the support arm 5; one of the drive rollers 11 is connected to a motor 12; an elastic belt 13 is sleeved between the drive rollers 11; a set of inclined peeling teeth 14 are evenly distributed on the outer side of the elastic belt 13, and the peeling teeth 14 protrude from the side of the support arm 5.

[0049] When floating objects collide with the side of the support arm 5 and are difficult to detach, especially some softer floating objects such as aquatic plants, branches, fabrics, rubber products, etc., the motor 12 can drive the drive roller 11 and elastic belt 13 to rotate. Then, the peeling teeth 14 located on the outside of the support arm 5 move towards the float 7, which can gradually push the floating objects on the side of the support arm 5 backward and separate them from the support arm 5, preventing the floating objects from squeezing the support arm 5 for a long time and increasing the driving resistance.

[0050] In another embodiment of the present invention, the floating body 7 is provided with an installation groove 15 on the side away from the surveying vessel 1; a guide wheel 16 is rotatably connected inside the installation groove 15; a set of paddles 17 are evenly distributed on the surface of the guide wheel 16, and the ends of the paddles 17 extend into and out of the floating body 7 through the installation groove 15; a flexible strip 18 is fixedly connected to the upper side of the paddles 17.

[0051] Pollutants such as algae, foam, oil, and suspended particles may exist on the water surface. When these pollutants remain on the surface of the probe 9 of the remote sensor 8 due to water flow or wave splashing, they will affect the mapping effect of the remote sensor 8. By setting up guide wheels 16, levers 17, and flexible strips 18, as the float 7 moves with the surveying vessel 1, the water flow passing by the outside of the mounting groove 15 can drive the levers 17 and guide wheels 16 to rotate. When the guide wheels 16 rotate into the inside of the float 7, their flexible strips 18 can sweep across the underside of the probe 9 and wipe away the dirt on the surface of the probe 9, maintaining the high transparency of the probe 9 and preventing dirt from affecting the transmission and reception of measurement signals.

[0052] An electromagnet 19 and a slide groove are respectively provided on the upper and lower sides of the mounting groove 15; a stop post 20 is slidably connected inside the slide groove; when the electromagnet 19 is energized, it attracts the stop post 20; the top of the stop post 20 is tapered, and a spring 21 is fixedly connected between the bottom of the stop post 20 and the slide groove.

[0053] After the flexible strip 18 cleans the probe 9, the electromagnet 19 is energized and attracts the baffle 20, which then moves upward into the mounting groove 15, thus braking the lever 17 and preventing it from rotating with the water flow. This avoids the lever 17 and the flexible strip 18 frequently passing under the probe 9 and affecting normal surveying work. In addition, the top of the baffle 20 is conical, which can naturally insert between adjacent levers 17. After the middle of the baffle 20 moves completely upward, the circumference of the baffle 20 is exactly in contact with the adjacent lever 17, thus completely locking and limiting the lever 17. At this time, there is no longer any lever 17 blocking the probe 9. If the surveying status of the remote sensor 8 is found to be poor, the electromagnet 19 can be de-energized, and the spring 21 can drive the baffle 20 to retract back into the groove. After that, the water flow can smoothly drive the lever 17 to rotate and clean the probe 9.

[0054] In another embodiment of the present invention, an annular sleeve 22 is fixedly connected inside the float 7, and the annular sleeve 22 is disposed on the outside of the remote sensor 8 and fits therewith; a cooling cavity is provided inside the annular sleeve 22; a water inlet groove 23 and a water outlet groove 24 are respectively opened on the front and rear sides of the float 7; the water inlet groove 23 and the water outlet groove 24 are both connected to the inside of the annular sleeve 22.

[0055] When the float 7 moves in the water, the external water flow enters the cooling chamber of the annular sleeve 22 through the water inlet 23. The water then disperses to both sides inside the annular sleeve 22, flows along the circumference of the annular sleeve 22, and finally converges into the water outlet 24 and flows outward. During this process, the water flows rapidly inside the annular sleeve 22, and the annular sleeve 22 is in close contact with the remote sensor 8, which can carry away the heat generated by the remote sensor 8 during operation, play a role in cooling and reducing the temperature, maintain the efficient working state of the remote sensor 8, and prevent the water from directly contacting the side of the remote sensor 8, thus preventing it from being corroded by the water.

[0056] Both the inlet tank 23 and the outlet tank 24 are equipped with filter screens to intercept impurities in the water and prevent them from entering the inlet tank 23, the annular sleeve 22 and the outlet tank 24 and causing blockages.

[0057] In another embodiment of the present invention, a baffle plate 25 is provided inside the annular sleeve 22; the baffle plate 25 has a wave-shaped design and is formed as an annular shape; a group of flow holes 26 are evenly distributed on the surface of the baffle plate 25.

[0058] By setting up the baffle plate 25, when the water flows into the annular sleeve 22 through the water inlet 23, it can be disturbed and blocked by the baffle plate 25. As a result, the water flows at the curved surface of the baffle plate 25. Part of the water continues to flow horizontally through the diversion hole 26 of the baffle plate 25, while the other part of the water flows up and down along the surface of the baffle plate 25. This allows the water to flow evenly and fully along the height direction of the annular sleeve 22. Furthermore, since these two parts of the water flow have different directions, they will collide and disperse with each other during the flow process, further promoting water flow turbulence and improving the uniformity of heat absorption for the remote sensor 8.

[0059] like Figure 9 As shown, the present invention discloses a method for using a high-resolution remote sensing mapping device, applicable to the aforementioned high-resolution remote sensing mapping device, comprising the following steps:

[0060] A1. The underwater topography is measured by a high-resolution remote sensing component carried on a surveying vessel 1. When the support arm 5 or the remote sensing component is impacted, the support arm 5 moves closer to the surveying vessel 1 and swings, and the damper 6 immediately contracts and absorbs the impact energy.

[0061] A2. The motor 12 drives the drive roller 11 and elastic belt 13 to rotate, and then the peeling teeth 14 located on the outside of the support arm 5 move towards the float 7, gradually pushing the floating objects on the side of the support arm 5 backward and separating them from the support arm 5.

[0062] A3. The water flow that sweeps across the outside of the mounting groove 15 drives the paddle 17 and the guide wheel 16 to rotate. When the guide wheel 16 rotates into the inside of the float 7, its flexible strip 18 sweeps across the underside of the probe 9 and wipes away the dirt on the surface of the probe 9.

[0063] A4. After the probe 9 is cleaned, the electromagnet 19 is energized and attracts the baffle 20, which then moves upward into the mounting groove 15, braking the lever 17 so that it cannot rotate with the water flow.

[0064] A5. When the float 7 moves in the water, the external water flow enters the cooling chamber of the annular sleeve 22 through the water inlet 23, and then the water flow disperses and flows to both sides inside the annular sleeve 22.

[0065] A6. A portion of the water continues to flow horizontally through the diversion hole 26 of the baffle 25, while another portion of the water flows up and down at an angle along the surface of the baffle 25. These two portions of water collide and disperse with each other during the flow process, and finally converge into the outlet tank 24 and flow outward.

[0066] The terms "front," "back," "left," "right," "top," and "bottom" all refer to the figures in the accompanying drawings. Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.

[0067] In the description of this invention, it should be understood that the terms "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
