Description

Technical Field

[0001] This invention relates to the field of ship hull modeling technology, specifically to a three-dimensional laser scanning device and measurement method for ship hull modeling based on data processing. Background Technology

[0002] A ship model is a scaled-down replica of a ship's hull or a ship-like object. It can be made of wood, paper, plastic, or other materials. When building or repairing a ship model, a 3D laser scanning device is required. During the scanning process, data processing technology can be used to assist in completing the modeling of the ship's hull.

[0003] Existing 3D laser scanning devices generally require a person to manually hold the laser scanner and walk around the ship model to achieve the 3D scanning effect. The scanning operation has a low degree of automation, and the handheld scanning method makes the scanner prone to shaking. Furthermore, the scanning speed and distance are difficult to control precisely, which affects the scanning accuracy. To address these issues, existing equipment needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a three-dimensional laser scanning device and measurement method for ship hull modeling based on data processing, in order to solve the problems mentioned in the background art. Existing three-dimensional laser scanning devices generally require manual hand-held laser scanners to circle the ship hull model to achieve the three-dimensional scanning effect. The scanning operation has a low degree of automation, and the hand-held scanning method makes the scanner prone to shaking, and the scanning speed and distance are difficult to control precisely, which affects the accuracy of the scanning.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a three-dimensional laser scanning device for ship hull modeling based on data processing, comprising a support frame, a three-dimensional laser scanning mechanism fixed to the inner bottom of the support frame, the three-dimensional laser scanning mechanism comprising a first motor, the top of the first motor being connected to a first incomplete gear, the upper side of the first incomplete gear being connected to a second incomplete gear via a third connecting shaft, a third spur gear being rotatably connected to the top of the support frame via a friction shaft, a carrier frame being fixed to the top of the support frame, the third spur gear penetrating the carrier frame, sliders being slidably connected to the inner wall and the inner top of the carrier frame, a laser scanner being fixed to one side of the slider, a protective cover being covered to the outer side of the carrier frame, and the second incomplete gear penetrating the protective cover.

[0006] Preferably, a first spur gear is meshed with one side of the first incomplete gear, and a first belt drive assembly is fixed to the top of the first spur gear. The first belt drive assembly is rotatably connected to the inner top of the support frame via a friction shaft, and the output end of the first belt drive assembly is connected to the intake pipe.

A fixed frame is fixed to the inner bottom of the support frame, the first connecting shaft is rotatably connected to the fixed frame, and the output end of the second belt drive assembly is connected to the suction fan via the second connecting shaft, with the suction fan extending into the suction pipe.

[0008] Preferably, the air intake pipe passes through the top of the support frame and is connected to the support platform, and the top of the support platform is fixed with an air intake channel, which is connected to the top of the air intake pipe through a connecting pipe.

[0009] Preferably, the upper side of the bottom of the support platform is connected to the adsorption and fixing mechanism through a first compression spring. The adsorption and fixing mechanism includes a movable pipe, and a first air intake hole is provided on the side of the movable pipe. A first through hole is provided on the top of the movable pipe, and a hollow ball is movably connected in the first through hole. A second air intake hole is provided on the bottom of the hollow ball.

[0010] Preferably, a second compression spring is fixed to the inner side of the hollow sphere, and an air suction head is fixed to the top of the second compression spring. The air suction head penetrates the top of the hollow sphere, and a washer is fixed to the top of the air suction head.

[0011] Preferably, the air intake channel has a second through hole, and the movable pipe passes through the second through hole.

[0012] Preferably, the third connecting shaft is rotatably connected to the top of the support frame, and a pressing block is fixed on one side of the third connecting shaft. A fixing block is fixed on the inner top of the support frame, and one side of the fixing block is connected to the movable frame through a third compression spring. Clips are symmetrically fixed on both sides of the movable frame.

[0013] Preferably, a first lead screw is fixed to the top of the third spur gear, and the first lead screw is rotatably connected to the side wall of the support frame. A first bevel gear is fixed to the top of the first lead screw, and a second bevel gear is meshed with one side of the first bevel gear. A second lead screw is fixed to one side of the second bevel gear, and the second lead screw is rotatably connected to the top of the support frame. A slider is threaded to the outer side of both the first lead screw and the outer side of the second lead screw.

[0014] A measurement method for ship hull modeling based on data processing includes the following steps:

[0015] S1. Place the ship model on the support platform. The first incomplete gear rotates, driving the first spur gear to rotate. The first belt drive assembly and the second spur gear rotate simultaneously. While the air intake pipe rotates, the air intake fan rotates. While the ship model rotates, the air intake head adsorbs and fixes the ship model.

[0016] S2. When the ship model rotates, two laser scanners scan the ship model. After the ship model rotates once, the extrusion block presses the movable frame to the right and moves it to the bottom. The clamp on the right side of the movable frame locks the friction shaft on the first belt drive assembly. Then, the first incomplete gear rotates, which drives the second incomplete gear to rotate, thereby driving the third round gear to rotate. The first lead screw and the second lead screw rotate at the same time. While the slider on the first lead screw moves up, the slider on the second lead screw moves to the right. The two laser scanners scan the ship model comprehensively.

[0017] S3. After the extrusion block leaves the movable frame, the movable frame automatically moves to the left to reset, and the left-side sleeve locks the friction shaft on the third sprocket.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This data-processing-based 3D laser scanning device for ship hull modeling, through the coordinated use of various components, achieves both adsorption fixation and automatic, comprehensive scanning. After placing the ship hull model on the support platform, the suction head rests against the bottom of the ship hull model, the suction fan rotates, and the suction head draws air downwards, thus adsorbing and fixing the ship hull model. Simultaneously, the suction pipe and support platform rotate as a whole, thus rotating the ship hull model 360 degrees. After each rotation of the ship hull model, the third circular gear rotates, the slider on the first lead screw moves upward, and at the same time, the slider on the second lead screw moves to the right. The two laser scanners can scan the sides and top of the ship hull model respectively, thereby automatically completing the 3D scanning work.

[0020] 2. This 3D laser scanning device for ship hull modeling based on data processing, through the coordinated use of various settings, can achieve the purpose of stable and close support. When the ship hull model is placed on the support platform, the movable pipe will abut against the bottom of the ship hull model, the hollow ball can move within the first through hole, and the air suction head can fit tightly against the ship hull model, making the support effect more stable and firm.

[0021] 3. The three-dimensional laser scanning device for hull modeling based on data processing can achieve locking by using the set mutual cooperation. During the rotation of the third connecting shaft, when the extrusion block presses the movable frame to the right, the right-side sleeve can lock the friction shaft on the first belt drive assembly. After the extrusion block leaves the movable frame, the movable frame moves to the left, and the left-side sleeve can lock the friction shaft on the third spur gear, which facilitates the self-locking effect.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-9 This invention provides a technical solution: a three-dimensional laser scanning device for ship hull modeling based on data processing, comprising a support frame 1, a three-dimensional laser scanning mechanism 2 fixed to the bottom inner side of the support frame 1, the three-dimensional laser scanning mechanism 2 comprising a first motor 201, the top of the first motor 201 being connected to a first incomplete gear 202, the upper side of the first incomplete gear 202 being connected to a second incomplete gear 220 via a third connecting shaft 218, the top of the support frame 1 being rotatably connected to a third spherical gear 221 via a friction shaft 222, a support frame 228 fixed to the top of the support frame 1, the third spherical gear 221 penetrating the support frame 228, sliders 232 being slidably connected to the inner wall and the inner top of the support frame 228, a laser scanner 234 fixed to one side of the slider 232, a protective cover 3 covering the outer side of the support frame 228, and the second incomplete gear 220 penetrating the protective cover 3.

[0034] In this embodiment, a first spur gear 203 is meshed with one side of the first incomplete gear 202, and a first belt drive assembly 204 is fixed to the top of the first spur gear 203. The first belt drive assembly 204 is rotatably connected to the inner top of the support frame 1 through a friction shaft 222, and the output end of the first belt drive assembly 204 is connected to the air intake pipe 205. The rotation of the first incomplete gear 202 can drive the first spur gear 203 to rotate, thereby driving the first belt drive assembly 204 to operate, thereby driving the air intake pipe 205 to rotate, and the support platform 212 to rotate accordingly, thereby rotating the ship model 360 degrees to smoothly complete the three-dimensional laser scanning operation.

[0035] In this embodiment, a second spur gear 206 is meshed with one side of the first spur gear 203, and the lower side of the second spur gear 206 is connected to the second belt drive assembly 209 through the first connecting shaft 207. A fixing frame 208 is fixed to the inner bottom of the support frame 1, and the first connecting shaft 207 is rotatably connected to the fixing frame 208. The output end of the second belt drive assembly 209 is connected to the suction fan 211 through the second connecting shaft 210, and the suction fan 211 extends into the suction pipe 205. The rotation of the first spur gear 203 can drive the second spur gear 206 to rotate, thereby driving the first connecting shaft 207 and the second belt drive assembly 209 to rotate, thereby driving the second connecting shaft 210 and the suction fan 211 to rotate, thereby automatically sucking air downwards.

[0036] In this embodiment, the air intake pipe 205 passes through the top of the support frame 1 and is connected to the support platform 212. The top of the support platform 212 is fixed with an air intake channel 213. The air intake channel 213 is connected to the top of the air intake pipe 205 through a connecting pipe 214. The connecting pipe 214 serves to connect the air intake pipe 205 and the air intake channel 213. When the air intake pipe 205 draws air downwards, the air intake channel 213 also draws air downwards, which facilitates the adsorption and fixation of the ship model.

[0037] In this embodiment, the upper side of the bottom of the support platform 212 is connected to the adsorption and fixing mechanism 216 via a first compression spring 215. The adsorption and fixing mechanism 216 includes a movable pipe 2161, and a first air intake hole 2162 is provided on the side of the movable pipe 2161. A first through hole 2163 is provided at the top of the movable pipe 2161, and a hollow ball 2164 is movably connected in the first through hole 2163. A second air intake hole 2165 is provided at the bottom of the hollow ball 2164. When the ship model is placed on the support platform 212, the movable pipe 2161 can press against the bottom of the ship model under the support of the first compression spring 215, which facilitates better support of the ship model.

[0038] In this embodiment, a second compression spring 2166 is fixed to the inner side of the hollow sphere 2164, and an air intake head 2167 is fixed to the top of the second compression spring 2166. The air intake head 2167 penetrates the top of the hollow sphere 2164, and a washer ring 2168 is fixed to the top of the air intake head 2167. The hollow sphere 2164 can move within the first through hole 2163. At the same time, the second compression spring 2166 provides support for the air intake head 2167. When the hull model is placed on the support platform 212, the air intake head 2167 can fit more flexibly and tightly against the hull model. The washer ring 2168 provides padding between the hull model and the air intake head 2167.

[0039] In this embodiment, a second through hole 217 is provided on the air intake channel 213, and the movable pipe 2161 passes through the second through hole 217. When the ship model is placed on the support platform 212, the movable pipe 2161 moves down and retracts into the air intake channel 213, and the first air intake hole 2162 is connected to the air intake channel 213.

[0040] In this embodiment, the third connecting shaft 218 is rotatably connected to the top of the support frame 1, and a pressing block 219 is fixed on one side of the third connecting shaft 218. A fixing block 223 is fixed on the inner top of the support frame 1, and one side of the fixing block 223 is connected to the movable frame 225 through the third compression spring 224. The movable frame 225 is symmetrically fixed with sleeves 226 on both sides. The rotation of the first incomplete gear 202 can drive the third connecting shaft 218 and the second incomplete gear 220 to rotate. When the pressing block 219 presses the movable frame 225 to the right, the right sleeve 226 will clamp the friction shaft 222 on the first belt drive assembly 204. After the pressing block 219 leaves the movable frame 225, the movable frame 225 can automatically spring open under the action of the third compression spring 224. The left sleeve 226 will clamp the friction shaft 222 on the third spur gear 221, which facilitates locking the first belt drive assembly 204 and the third spur gear 221 in turn.

[0041] In this embodiment, a first lead screw 227 is fixed to the top of the third spur gear 221, and the first lead screw 227 is rotatably connected to the side wall of the support frame 228. A first bevel gear 229 is fixed to the top of the first lead screw 227, and a second bevel gear 230 is meshed with one side of the first bevel gear 229. A second lead screw 231 is fixed to one side of the second bevel gear 230, and the second lead screw 231 is rotatably connected to the top of the support frame 228. Both the outer sides of the first lead screw 227 and the outer sides of the second lead screw 231 are threaded. The slide block 232 is connected to the first lead screw 227. When the first lead screw 227 rotates, the corresponding slide block 232 can slide upward under the limiting action of the first lead screw 227 and the support frame 228. The rotation of the first lead screw 227 will drive the first bevel gear 229 to rotate, thereby driving the second bevel gear 230 to rotate. The second lead screw 231 will rotate accordingly. At this time, the corresponding slide block 232 can slide to the right under the limiting action of the second lead screw 231 and the support frame 228. At the same time, the hull model rotates 360 degrees, which facilitates the automatic three-dimensional scanning effect.

[0042] According to another aspect of the present invention, a measurement method for ship hull modeling based on data processing is provided, comprising the following steps:

[0043] A measurement method for ship hull modeling based on data processing includes the following steps:

[0044] S1. Place the ship model on the support platform 212. The first incomplete gear 202 rotates, driving the first spur gear 203 to rotate. The first belt drive assembly 204 and the second spur gear 206 rotate simultaneously. While the air intake pipe 205 rotates, the air intake fan 211 rotates. While the ship model rotates, the air intake head 2167 adsorbs and fixes the ship model.

[0045] S2. When the ship model rotates, two laser scanners 234 scan the ship model with lasers. After the ship model rotates once, the pressing block 219 presses the movable frame 225 to the right and moves it to the bottom. The clamp 226 on the right side of the movable frame 225 locks the friction shaft 222 on the first belt drive assembly 204. Then, the first incomplete gear 202 rotates and drives the second incomplete gear 220 to rotate, thereby driving the third spur gear 221 to rotate. The first lead screw 227 and the second lead screw 231 rotate at the same time. While the slider 232 on the first lead screw 227 moves upward, the slider 232 on the second lead screw 231 moves to the right. The two laser scanners 234 scan the ship model comprehensively.

[0046] S3. After the extrusion block 219 leaves the movable frame 225, the movable frame 225 automatically moves to the left to reset, and the left-side sleeve 226 locks the friction shaft 222 on the third sprocket 221.

[0047] The working principle of this device is as follows: First, open the protective cover 3, place the ship model on the support platform 212, and then close the protective cover 3. The movable pipe 2161 moves down and rests against the bottom of the ship model. The first air intake 2162 is connected to the air intake channel 213. The use of hollow ball 2164, air intake head 2167, and washer ring 2168 can more closely support the ship model. Two laser scanners 234 scan the side and top of the ship model respectively. The first incomplete gear 202 rotates, thereby driving the first sprocket 203 to rotate, which in turn drives the second sprocket 206. The first connecting shaft 207, the second belt drive assembly 209, the second connecting shaft 210, and the suction fan 211 rotate, causing the suction pipe 205 and the suction channel 213 to draw air downwards. The suction head 2167 adheres to and fixes the hull model. The rotation of the first spur gear 203 drives the first belt drive assembly 204, the suction pipe 205, and the support platform 212 to rotate, thus rotating the hull model 360 degrees. The rotation of the first incomplete gear 202 drives the rotation of the third connecting shaft 218 and the second incomplete gear 220. When the pressing block 219 presses against the movable frame 225 and moves to the right, the left-side clamp 226... The friction shaft 222 on the third sprocket 221 is disengaged, thus releasing the lock on the third sprocket 221. When the right-side clamp 226 clamps the friction shaft 222 on the first belt drive assembly 204, it can lock the first belt drive assembly 204. Then, the second incomplete gear 220 rotates along with the rotation of the first incomplete gear 202, thereby driving the third sprocket 221 to rotate, which in turn drives the first lead screw 227 and the second lead screw 231 to rotate. When the slider 232 on the first lead screw 227 moves upward, the slider 232 on the second lead screw 231 moves to the right. Each time the hull model rotates... As the device rotates, the two sliders 232 move a certain distance each time, thus achieving the effect of three-dimensional scanning. After the extrusion block 219 leaves the movable frame 225, the movable frame 225 moves to the left, and the right-side clamp 226 leaves the friction shaft 222 on the first belt drive assembly 204, thereby releasing the lock on the first belt drive assembly 204. When the left-side clamp 226 clamps the friction shaft 222 on the third sprocket 221, it can lock the third sprocket 221. This is the working principle of the device, and the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The first incomplete gear (202) rotates, driving the first spur gear (203) to rotate. The first belt drive assembly (204) and the second spur gear (206) rotate simultaneously. While the air intake pipe (205) rotates, the air intake fan (211) rotates. While the ship model rotates, the air intake head (2167) adsorbs and fixes the ship model. S2. When the ship model rotates, two laser scanners (234) scan the ship model with lasers. After the ship model rotates once, the extrusion block (219) presses the movable frame (225) to the right and moves to the bottom. The clamp (226) on the right side of the movable frame (225) locks the friction shaft (222) on the first belt drive assembly (204). Then the first incomplete gear (202) rotates and drives the second incomplete gear (220) to rotate, thereby driving the third round gear (221) to rotate. The first lead screw (227) and the second lead screw (231) rotate at the same time. While the slider (232) on the first lead screw (227) moves up, the slider (232) on the second lead screw (231) moves to the right. The two laser scanners (234) scan the ship model in its entirety. S3. After the extrusion block (219) leaves the movable frame (225), the movable frame (225) automatically moves to the left to reset, and the left sleeve (226) locks the friction shaft (222) on the third sprocket (221).
