Technical Field

[0001] The present invention relates to the technical field of water area surveying and mapping, and particularly relates to a water area surveying and mapping device for marine engineering surveying and mapping. Background Art

[0002] A seabed water area surveying and mapping device is an instrument used for surveying and mapping the seabed environment and data. It is placed deep in the seabed. By moving the device, relevant data of the seabed water area can be surveyed and collected, and it is widely used in work fields such as marine resource development, marine engineering construction, and marine environmental monitoring.

[0003] When the seabed water area surveying and mapping device moves in seawater for surveying and mapping operations, due to the complex and changeable marine environment, the flow of seawater has different directions and speeds, and there are differences at different depths and regions. This causes the surveying and mapping device to be difficult to resist the impact of seawater only relying on its own power in the absence of effective traction guidance. During the movement of the surveying and mapping device, it is easy to deviate in seawater, deviating from the originally set surveying and mapping route. This deviation not only affects the stability of the device operation and the surveying and mapping efficiency, but also easily interferes with the surveying and mapping accuracy. Seriously, it may even cause errors in the seabed depth data, resulting in serious consequences.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, by lowering the base to the seabed as an anchor point, connecting and towing it with a towing rope, and cooperating with the installation of a first electric propeller to provide a driving force for the surveying and mapping body to move away from the base, and setting a second electric propeller to provide a driving force for the surveying and mapping body to rotate around the base, the surveying and mapping body can drive the first probe to rotate stably around the base for circular surveying and collection. Cooperating with the take-up reel driven by the first servo motor to wind up the towing rope, the distance between the surveying and mapping body and the base can be gradually reduced, realizing comprehensive and stable coverage surveying of the surrounding waters. During the surveying process, the movement is stable, and the surveying and mapping body is not easily offset by the water flow impact, which improves the surveying stability and accuracy of the device to a certain extent; 2. In the present invention, by setting two take-up reels symmetrically up and down, and setting two towing ropes respectively connected between the surveying and mapping body and the two take-up reels, and cooperating with the driving force provided after the first electric propeller is started, a triangular structure can be formed between the surveying and mapping body and the two take-up reels.

In the present invention, by sleeving the protective shell outside the upper and lower take-up reels, the towing rope wound on the take-up reel can be protected, reducing the entanglement of foreign objects during the winding and release of the towing rope, which ensures the stability of the device operation to a certain extent. At the same time, by setting a second servo motor to drive the protective shell to rotate, and cooperating with the first servo motor to drive the take-up reel to rotate, the take-up reel, the protective shell and the surveying and mapping body can rotate synchronously, which is beneficial to ensuring the stability when the towing rope is connected between the take-up reel and the surveying and mapping body and applying traction to the surveying and mapping body; 4. In the present invention, by installing two micro pumps connected to the chamber in the surveying and mapping body, and cooperating with the water pressure sensor to measure the water depth where the surveying and mapping body is located through water pressure, the empty space in the chamber can be regulated by pumping water, and then the overall buoyancy of the surveying and mapping body can be adaptively adjusted, so that the surveying and mapping body can always move in a circular motion on the same horizontal plane for surveying operations, which is beneficial to further improving the stability of the device's surveying operations; 5. In the present invention, by rotatably installing the sleeve outside the rope passing hole and fixedly installing a brush plate in the sleeve, and by virtue of the meshing of the third gear and the toothed ring, when the second servo motor drives the protective shell to rotate, the sleeve can be driven to rotate, driving the brush plate to wash and clean the outer surface of the towing rope. At the same time, by setting the brush plate as a spiral structure, an axial conveying force will be generated during its rotation to export the debris cleaned from the towing rope outside the sleeve, which can avoid the continuous accumulation of foreign objects in the sleeve during the wiping and cleaning process, and improve the stability of the device during operation to a certain extent.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment: This embodiment provides a water area surveying device for ocean engineering surveying. Refer to Figure 1 - Figure 12 , specifically, it includes a base 1. A bearing platform 101 is installed on the top of the base 1, and a waterproof cabin 103 is fixedly installed at the bottom of the bearing platform 101. A vertical rod 104 is fixed on the top of the bearing platform 101, and a hanging ring 105 is fixed at the top end of the vertical rod 104. A first shaft cylinder 2 is rotatably sleeved outside the vertical rod 104, and a winding wheel 201 is fixedly installed on the first shaft cylinder 2. A traction rope 202 is orderly wound outside the winding wheel 201. A first servo motor 203 is fixed in the waterproof cabin 103. The outer end of the traction rope 202 is fixedly connected to a surveying and mapping body 3, and a chamber 301 is arranged in the surveying and mapping body 3. A first electric propeller 302 is fixedly installed on one side of the surveying and mapping body 3 connected to the traction rope 202. A second electric propeller 303 is fixedly installed on the outer end wall of the surveying and mapping body 3, and the second electric propeller 303 is perpendicular to the first electric propeller 302. A first probe 304 is fixedly installed at the bottom of the surveying and mapping body 3. The bottom end of the vertical rod 104 is fixedly connected inside the waterproof cabin 103. The lower end of the first shaft cylinder 2 is rotatably connected inside the waterproof cabin 103. A first disc 5 arranged inside the waterproof cabin 103 is fixedly installed at the lower end of the first shaft cylinder 2. A first gear 501 meshing with the first disc 5 is fixedly installed on the driving shaft of the first servo motor 203.

[0021] When the device is in use, a steel cable is connected to the hanging ring 105 through a hook. The staff lowers the device steadily to the seabed through the steel cable to prepare for underwater mapping operations. During the mapping process, operations such as photographing and collecting the terrain in the underwater area and measuring the undulating data of the seabed are completed. During operation, the overall buoyancy of the mapping body 3 is balanced through the chamber 301, so that the mapping body 3 can float in the seawater at the seabed. Then, the first electric propeller 302 is powered on and started. Through the reverse driving force provided by the rotation of the fan blades in the first electric propeller 302, the mapping body 3 is driven to move away from the reel 201 along the horizontal plane. During this process, the first servo motor 203 is powered on and started, driving the first gear 501 fixed on its drive shaft to rotate. Then, with the meshing of the first gear 501 and the first disc 5, the first shaft tube 2 is driven to drive the reel 201 to rotate, and the towing rope 202 wound around the outside of the reel 201 and connected to the mapping body 3 is orderly released according to the distance that the mapping body 3 moves outward. During the process of releasing the towing rope 202, due to the outward traction of the mapping body 3, the released towing rope 202 is always in a taut state.

[0022] When the towing rope 202 is completely released, it is connected between the reel 201 and the mapping body 3. In this state, the mapping body 3 is at the limit position that can be reached. Then, the second electric propeller 303 is controlled to be powered on and started to Figure 1 take the middle view as an example. The mapping body 3 is on the left side of the base 1. The first electric propeller 302 is fixedly installed on the right end wall of the mapping body 3. When the first electric propeller 302 is started, the mapping body 3 is pushed to move horizontally to the left away from the base 1, while the second electric propeller 303 is fixedly installed on the front end wall of the mapping body 3. When the second electric propeller 303 is powered on and started, it will push the mapping body 3 to rotate clockwise around the base 1. During this process, the first probe 304 installed at the bottom of the mapping body 3 is powered on and started to conduct mapping and measurement operations on the underwater area below. During this process, the first electric propeller 302 is always started to push the mapping body 3 to keep moving away from the base 1, and the length of the towing rope 202 connected between the reel 201 and the mapping body 3 no longer changes, so that the mapping body 3 can drive the first probe 304 to rotate stably around the base 1.

[0023] After the surveying and mapping body 3 drives the first probe 304 to rotate around the base 1 for one circle, the first servo motor 203 is energized and starts in the reverse direction, driving the winding wheel 201 to rotate in the reverse direction, and stably winding a certain length of the traction rope 202 that is released outward. After the surveying and mapping body 3 rotates around the base 1 for one circle, the distance between the surveying and mapping body 3 and the winding wheel 201 is actively shortened, and the surveying and mapping body 3 is pulled closer to the base 1. Then, under the push of the second electric propeller 303, the surveying and mapping body 3 continues to rotate around the base 1 for one circle, and data collection and surveying operations are carried out synchronously during the rotation process. Repeat the above operations, and through the orderly coverage of circles, complete the surveying and mapping operations of the sea area around the lowering position of the device.

[0024] During the process of carrying out underwater surveying and mapping operations, through the push of the first electric propeller 302, the surveying and mapping body 3 is kept in a posture away from the base 1, so that the traction rope 202 connected between the winding wheel 201 and the surveying and mapping body 3 can stably traction the surveying and mapping body 3. Then, through the push of the second electric propeller 303, the surveying and mapping body 3 is driven to drive the first probe 304 to rotate around the base 1 in a circular motion for circumferential surveying and mapping operations. Then, through the rotation of the winding wheel 201, the distance of the surveying and mapping body 3 is gradually shortened after the surveying and mapping body 3 makes circles, and the underwater surveying and mapping operations are completed. The device is positioned through the main body part and traction is carried out through the traction rope 202, so that the operation of the surveying and mapping body 3 around the base 1 in the sea water is orderly and stable, and it is not easy to deviate in position due to the flow of sea water. The operation is convenient, and the accuracy of underwater surveying and mapping operations can be effectively improved.

[0025] In the specific implementation process, such as Figure 2 、 Figure 9 and Figure 11 shown, the bearing platform 101 is movably installed on the top of the base 1. Electric push rods 102 vertically arranged are fixedly installed at the four corner positions inside the base 1, and the telescopic ends above the electric push rods 102 are fixedly connected to the bearing platform 101. When the device is in use, the staff can control the bearing platform 101 to rise by moving the telescopic ends of the electric push rods 102, so as to realize the up and down adjustment of the structure on the bearing platform 101. This enables the device, after being lowered to the seabed, to adjust the height of the horizontal plane of the circumferential movement of the surveying and mapping body 3 according to actual surveying and mapping requirements, with convenient operation, and can effectively improve the flexibility of the device during actual use.

[0026] In the specific implementation process, such as Figure 1 、 Figure 4 and Figure 9As shown, there are two winding wheels 201 in total. The two winding wheels 201 are symmetrically arranged up and down. The traction ropes 202 are orderly wound around the outer sides of each winding wheel 201. The two traction ropes 202 are fixedly connected to the same end wall of the surveying and mapping body 3. When the device is in use, there are two winding wheels 201 in total, and one traction rope 202 is led out from each winding wheel 201 for fixedly connecting with the surveying and mapping body 3. This enables the surveying and mapping body 3 to form a triangular connection structure between the surveying and mapping body 3 and the upper and lower two winding wheels 201 when moving around the base 1 for underwater water area surveying operations. By virtue of the high stability of the triangular structure, the probability of the surveying and mapping body 3 tilting upward or downward during the circular motion under the traction of the traction ropes 202 can be effectively reduced, which is beneficial to further improving the stability and accuracy of the device during actual underwater surveying.

[0027] In the specific implementation process, as Figure 5 and Figure 9 shown, a protective shell 204 is sleeved on the outer sides of the two winding wheels 201. Two rope passing holes 205 are opened on the outer end wall of the protective shell 204. The two traction ropes 202 respectively pass through the corresponding rope passing holes 205 movably. The bottom of the protective shell 204 is fixedly installed with a second shaft cylinder 206 which is movably sleeved on the outside of the first shaft cylinder 2, and the second shaft cylinder 206 is installed on the bearing platform 101. The lower end of the second shaft cylinder 206 is rotatably connected in the waterproof cabin 103. A second servo motor 207 is fixedly installed in the waterproof cabin 103. A second round plate 502 arranged in the waterproof cabin 103 is fixedly installed at the lower end of the second shaft cylinder 206. A second gear 503 meshing with the second round plate 502 is fixedly installed on the driving shaft of the second servo motor 207. When the device is in use, the protective shell 204 is sleeved on the outer sides of the upper and lower two winding wheels 201, which can protect the traction ropes 202 wound on the winding wheels 201 and reduce the entanglement of foreign objects during the winding and releasing processes of the traction ropes 202, and can ensure the stability of the device during operation to a certain extent.

[0028] When the surveying and mapping body 3 makes a circular motion around the base 1 under the traction of the traction rope 202, in order to prevent the traction rope 202 connected between the winding wheel 201 and the surveying and mapping body 3 from winding around the outside of the protective shell 204. At this time, the device can control the second servo motor 207 to be powered on and started, driving the second gear 503 fixedly installed on the drive shaft of the second servo motor 207 to rotate. Then, with the meshing of the second gear 503 and the second disc 502, the second disc 502 is driven to rotate, and finally the protective shell 204 is driven to rotate. In this state, the rotation speed of the protective shell 204 is the same as the rotation speed of the surveying and mapping body 3 around the base 1, that is, their angular velocities of rotation are the same. Synchronously, the first servo motor 203 will be started synchronously, driving the winding wheel 201 to rotate synchronously and in the same direction as the winding wheel 201 inside the protective shell 204, so that the winding wheel 201 and the protective shell 204 are in a relatively synchronous state, avoiding the traction rope 202 from being involved due to the speed difference between the winding wheel 201 and the protective shell 204. With the above structures cooperating with each other, the stability of the device during operation can be further improved, ensuring the stability of the traction rope 202 when it is connected between the winding wheel 201 and the surveying and mapping body 3 and applying traction to the surveying and mapping body 3.

[0029] In the specific implementation process, as Figure 9 shown, two micro pumps are fixedly installed inside the surveying and mapping body 3. The water outlet of one micro pump is communicated with the inside of the chamber 301, and the water inlet of the other micro pump is communicated with the inside of the chamber 301. A water pressure sensor 305 is fixedly installed on the outer end wall of the surveying and mapping body 3. When the device is in use, the water inlet of the first micro pump and the water outlet of the second micro pump are both communicated with the outside of the surveying and mapping body 3. This enables the device to adjust the size of the empty space inside the chamber 301 through the two micro pumps when it sinks to the seabed for surveying. By starting the first micro pump, seawater from the outside can be pumped into the chamber 301, and by starting the second micro pump, the seawater injected into the chamber 301 can be pumped out again, thus realizing the flexible adjustment of the empty space inside the chamber 301. Furthermore, the device can flexibly adjust the actual buoyancy of the surveying and mapping body 3 when it sinks into the seawater according to the actual usage situation. Through adjustment, it can be leveled on the horizontal plane at the middle position between the upper and lower winding wheels 201. With the traction of the two traction ropes 202, the stability of the surveying and mapping body 3 driving the first probe 304 to conduct circular surveying along the same horizontal plane can be further ensured.

[0030] The water pressure sensor 305 installed on the outer end wall of the surveying and mapping body 3 can detect the water pressure at the position where the surveying and mapping body 3 is located in real time. According to the underwater water pressure data, the seawater depth at the position where the surveying and mapping body 3 is located can be detected in real time. It can not only detect the horizontal position during the movement of the surveying and mapping body 3, but also cooperate with two micro pumps to accurately control the empty space in the chamber 301, so as to realize the offset adjustment of the vertical position of the surveying and mapping body 3 in the seawater. Normally, the surveying and mapping body 3 moves on the horizontal plane at a specific depth of the sea level. After the measurement and judgment by the water pressure sensor 305, if the position of the surveying and mapping body 3 rises in the seawater, the water pressure detected by the water pressure sensor 305 decreases. At this time, the first micro pump starts to pump the external seawater into the chamber 301, reducing the overall buoyancy of the surveying and mapping body 3, so that the surveying and mapping body 3 descends and adjusts. If the position of the surveying and mapping body 3 decreases in the seawater, the water pressure detected by the water pressure sensor 305 increases. At this time, the second micro pump starts to pump the seawater in the chamber 301 to the outside, increasing the overall buoyancy of the surveying and mapping body 3, so that the surveying and mapping body 3 rises and adjusts. With the mutual cooperation, the monitoring and adjustment of the position height of the surveying and mapping body 3 are automatically realized, and the operation is flexible and convenient.

[0031] In the specific implementation process, such as Figure 1 、 Figure 3 and Figure 12 shown, a drainage plate 306 is fixedly installed on the outer end wall of the surveying and mapping body 3, and the drainage plate 306 is symmetrically arranged with the second electric propeller 303. Taking Figure 1 as an example, the second electric propeller 303 is installed on the front end wall of the surveying and mapping body 3, then the drainage plate 306 is installed on the back end wall of the surveying and mapping body 3. When the second electric propeller 303 starts to push the surveying and mapping body 3 to rotate clockwise around the base 1, the drainage plate 306 is at the front end of the moving direction of the surveying and mapping body 3. The end of the drainage plate 306 away from the surveying and mapping body 3 is set as an arc structure. This enables the drainage plate 306 to assist in breaking through the water flow during the movement of the surveying and mapping body 3, reducing the water flow resistance suffered by the surveying and mapping body 3 when moving in the seawater, and can effectively improve the smoothness of the surveying and mapping body 3 during the movement, which is beneficial to ensuring the stability of the operation of the device.

[0032] In the specific implementation process, such as Figure 9As shown, a second probe 4 is fixedly installed at the bottom of the base 1, and the second probe 4 is recessed and installed at the bottom of the base 1. A protective glass 401 covering the lower part of the second probe 4 is fixedly installed at the bottom of the base 1. When the device is in use and being lowered to the seabed, the second probe 4 installed at the bottom of the base 1 is powered on and starts. Through the protective glass 401, the seabed waters directly below the base 1 can be surveyed. Cooperating with the surveying operation of the surrounding seabed waters during the circumferential movement of the first probe 304 at the bottom of the surveying body 3, it can effectively reduce the surveying corners and is beneficial to improving the comprehensiveness of the seabed waters surveying operation. Support feet are provided at the four corner positions of the bottom of the base 1. With the support of the support feet, when the device is lowered to the seabed, the bottom of the base 1 does not directly contact the seabed. Cooperating with the installation of the protective glass 401 below the second probe 4 to protect the second probe 4 can, to a certain extent, ensure the stable safety of the second probe 4 during operation.

[0033] In the specific implementation process, such as Figure 6 、 Figure 7 and Figure 10 - Figure 11As shown, a sleeve 6 that is movably sleeved outside the corresponding traction rope 202 is rotatably installed on the outer side of each rope-passing hole 205. A brush plate 601 is fixedly installed on the inner end wall of the sleeve 6, and the brush plate 601 is arranged in a spiral structure. A third gear 602 is fixedly installed on the sleeve 6 located below. A tooth ring 603 coaxially arranged with the second shaft cylinder 206 is fixedly installed on the top of the bearing platform 101, and the tooth ring 603 is meshed and connected with the third gear 602. The upper and lower sleeves 6 are drivingly connected. When the device is in use, during the process of the surveying body 3 moving around the base 1, the protective shell 204 will rotate synchronously under the drive of the second servo motor 207, and the take-up wheel 201 will also rotate under the drive of the first servo motor 203, gradually taking up the traction rope 202 connected between the take-up wheel 201 and the surveying body 3 on the take-up wheel 201, and gradually shortening the distance between the surveying body 3 and the base 1 during the movement of the surveying body 3 around. During this process, the protective shell 204 rotates relative to the bearing platform 101, so that the third gear 602 and the tooth ring 603 rotate relative to each other. With the meshing of the third gear 602 and the tooth ring 603, when the tooth ring 603 keeps its position constant, the third gear 602 is driven to rotate, so that the upper and lower sleeves 6 are driven to rotate. The two sleeves 6 are respectively sleeved outside the two traction ropes 202 and rotate, driving the brush plate 601 fixedly installed inside to rotate on the outside of the traction rope 202, realizing the cleaning of the traction rope 202. Cooperating with the take-up wheel 201 taking up the traction rope 202 to drive the traction rope 202 to move, the outer surface of the traction rope 202 can be automatically cleaned during the recovery process of the traction rope 202, which is beneficial to reducing the probability of underwater foreign objects following the traction rope 202 and winding into the protective shell 204, and ensuring the stability of the device during long-term operation to a certain extent.

[0034] The brush plate 601 installed in the sleeve 6 is arranged in a spiral structure, which makes an axial conveying force generated in the sleeve 6 during the rotation of the brush plate 601. This axial conveying force is outward along the central axis of the sleeve 6. During the rotation, the foreign objects wiped off from the traction rope 202 can be led out of the sleeve 6, which is beneficial to avoiding the continuous accumulation of foreign objects inside the sleeve 6 during the wiping and cleaning process, and improving the stability of the device during operation to a certain extent.

[0035] Specifically, the working principle and operation method of the present invention are as follows: The staff connects the steel cable to the hanging ring 105, and then lowers the device to the seabed. During the lowering process of the device, the second probe 4 installed at the bottom of the base 1 is powered on and starts to conduct mapping operations on the seabed water area directly below the base 1. When the device reaches the seabed, two micro pumps installed in the mapping body 3 are powered on and start to control the size of the empty space in the pumping control chamber 301, adjusting the overall buoyancy of the mapping body 3 so that the mapping body 3 floats in the sea water. Then, the first electric propeller 302 is powered on and starts to drive the mapping body 3 to move away from the base 1 through the reaction force. Synchronously, the first servo motor 203 is powered on and drives the winding wheel 201 to rotate, slowly releasing the towing rope 202. When the mapping body 3 moves to the preset position, the second electric propeller 303 is powered on and, under the traction of the towing rope 202, drives the mapping body 3 to rotate around the base 1 on the same horizontal plane. During this process, the first probe 304 installed at the bottom of the mapping body 3 is powered on and starts to conduct mapping operations on the seabed water area along the moving path of the mapping body 3. During the circular motion of the mapping body 3, the second servo motor 207 is powered on and drives the protective shell 204 to rotate synchronously with the mapping body 3. The first servo motor 203 drives the winding wheel 201 to rotate synchronously with the protective shell 204 to keep the distance between the mapping body 3 and the base 1 constant. When the mapping body 3 makes a full circle of circular movement, the first servo motor 203 drives the winding wheel 201 to rotate further, winding part of the towing rope 202 on the winding wheel 201, so that the mapping body 3 is pulled closer to the base 1 by a certain distance. Then, the mapping body 3 continues to rotate around the base 1 for a circle to conduct mapping and collection. The above operations are repeated until the comprehensive collection operations are completed for the water area within the coverage area of the device. The relevant data collected is transmitted to the corresponding server and sorted to generate the overall map of the water area mapping information. During the mapping process, the position height of the bearing platform 101 is adjusted through the electric push rod 102, which can change the operation plane of the mapping body 3, and the operation is flexible and convenient.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
