Description

[0002] During the process of national territorial space planning, in order to efficiently and reasonably utilize the land in different regions, it is necessary to investigate and record the geological conditions and human conditions of the region, and then conduct comprehensive analysis and planning. In order to make the formulated plan more intuitive, it is often necessary to use a sand table for display. The sand table for national territorial space planning refers to using a sand table model to display and simulate the terrain, traffic, resource distribution, etc. of different regions during the process of planning and constructing national territorial space, helping planners more intuitively understand the overall layout and the effect of the planning scheme.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, with the cooperation of the dynamic detection and adjustment component, after the chip drive board receives the control signal from the external logic controller, it sends a new control instruction to the transmission control motor, causing the transmission control motor to start after receiving the drive signal. The large gear connected to its output end rotates accordingly. The rotation of the large gear is transmitted to the synchronous shaft through the chain gear. When the chain gear meshes with the large gear and drives the synchronous shaft to rotate, the first bevel gear and the second bevel gear on the synchronous shaft are engaged with each other simultaneously, thereby effectively adjusting the rotation direction of the connecting transmission short shaft and reducing speed and increasing torque. The connecting transmission short shaft drives the inner rotating frame to rotate inside the outer rotating frame, and the outer rotating frame can rotate synchronously under the cooperation of the side rotating track shaft column. The relative synchronous adjustment formed by the outer rotating frame and the inner rotating frame enables the real-time three-dimensional scanner to perform omnidirectional processing and analysis scanning on the materials printed in the prefabricated sand table in three-dimensional space and transmit them to the modeling display screen, enabling real-time modeling according to the adjustment of the prefabricated sand table, facilitating the adjustment of the real-time sand table model, realizing the high dynamic and personalized customization of the display scene, enhancing the interactivity and expressiveness of the display, and effectively adjusting the overall sand table display according to the development and change of the time series.

[0018] 2. In the present invention, with the cooperation of the sand table module adjustment component, the main drive angle motor starts to work, driving the assembly turntable inside the main rotating groove plate to rotate slowly and smoothly. With the four groups of quick assembly installation grooves, the staff can quickly insert different assembled sand tables in place. Each installation groove is designed with a quick installation structure to ensure that the assembled sand table can be quickly installed inside the rotating groove track plate, making the installation simple and fast. When the assembled sand table is installed, the secondary rotation motor starts. The secondary rotation motors are respectively located at the bottoms of the four rotating groove track plates and can work independently or cooperatively according to the instructions of the external logic controller, enabling each rotating groove track plate and the sand table module on it to perform their respective rotation operations. At the same time, the rotation of the main rotating groove plate and the rotation of the assembled sand table driven by the secondary rotation motor form two operation modes. The specific mode one is that the main drive angle motor drives the assembly turntable and the entire sand table to rotate, so that the four groups of assembled sand tables installed can each form a sand table display of the four seasons. The specific mode two is that the above-mentioned secondary rotation motor drives the assembled sand table to rotate independently, which can be located under the printing nozzle, facilitating the formation of real-time adjustment of the sand table model, realizing the high dynamic and personalized customization of the display scene, enhancing the interactivity and expressiveness of the display. And through the installed weather simulation device, the dual operation modes of the overall rotation display of the sand table and the independent rotation of a single module are effectively realized. It can not only display the macroscopic scene of the seasonal changes, but also perform refined and personalized local dynamic displays, improving the interactivity and expressiveness of the display. At the same time, the design of the quick assembly installation groove simplifies the replacement process of the sand table module and improves work efficiency.

[0019] 3. In the present invention, with the cooperation of the multi-dimensional printing component, the synchronous control motor is used to drive the horizontal linear guide and the longitudinal lead screw guide, so that the installation bracket plate and the printing box translate along the X-Y axis. At the same time, the printing nozzle precisely lifts in the Z-axis direction under the guidance of the vertical linear guide, enabling the printing nozzle to accurately control the deposition amount and distribution of the resin under the auxiliary monitoring of the high-definition camera end, and layer by layer stacking to construct an object. And the high-definition camera end can perform real-time photography on the formed model for display on the modeling display screen. At the same time, during the printing process, the printing nozzle automatically adjusts the angle according to the complexity of the model, and ensures the printing quality on various inclined surfaces and complex structures through automatic angle rotation, enhancing the structural stability and detail restoration degree, realizing the high-precision layer-by-layer construction, real-time monitoring and dynamic display replacement of the model, and further increasing the dynamic display of the sand table showing the development and changes of the time series.

A real-time three-dimensional scanner 9094 is installed at the axial center end of the chip driving board 9092.

[0030] According to Figure 1 - Figure 3As shown in the figure, the sand table module adjustment component 10 includes a main rotating groove disk 101. A main driving angle motor is installed at the bottom axis end of the main rotating groove disk 101. An assembly turntable is rotatably connected inside the main rotating groove disk 101. Four groups of quick assembly mounting grooves 102 are equally arranged on the top wall surface of the assembly turntable. A rotating groove track disk 103 is installed on the inner surface of the four groups of quick assembly mounting grooves 102. First, when performing the assembly type sand table operation for territorial space planning, the power supply can be connected to make the main driving angle motor start to work, driving the assembly turntable inside the main rotating groove disk 101 to rotate slowly and smoothly. By using the four groups of quick assembly mounting grooves 102, the staff can quickly insert different assembly type sand tables 104 in place. Each mounting groove is designed with a quick installation structure (such as connecting flange, pneumatic connector, self-tapping screw, quick-release screw, and magnetic connector, etc.) to ensure that the assembly type sand table 104 can be quickly installed inside the rotating groove track disk 103, making the installation simple and fast.

[0031] According to Figure 3 As shown in the figure, an assembly type sand table 104 is rotatably connected inside the rotating groove track disk 103. A secondary rotating motor is installed at the bottom of the rotating groove track disk 103. The secondary rotating motor is installed in the surface grooves of the four groups of quick assembly mounting grooves 102.

The secondary rotating motors are respectively located at the bottoms of the four rotating groove track disks 103 and can work independently or cooperatively according to the instructions of the external logic controller, enabling each rotating groove track disk 103 and the sand table module thereon to perform their respective rotating operations. At the same time, the rotation of the main rotating groove disk 101 and the rotation of the secondary rotating motor driving the assembly type sand table 104 form two working modes. The specific mode one is that the main driving angle motor drives the assembly turntable and the entire sand table to rotate, so that the four groups of assembly type sand tables 104 installed can each form a sand table display of four seasons.

It can be located below the printing nozzle 8090, facilitating the formation of real-time sand table model adjustment, realizing the high dynamic and personalized customization of the display scene, and enhancing the interactivity and expressiveness of the display.

[0032] According to Figure 1 - Figure 5 As shown in the figure, the multi-dimensional printing component 8 includes two groups of horizontal linear rails 801. A synchronous control motor 802 is installed at the side end of the two groups of horizontal linear rails 801. A longitudinal lead screw rail 803 is slidably connected inside the two groups of horizontal linear rails 801. By using the synchronous control motor 802 to drive the horizontal linear rails 801 and the longitudinal lead screw rail 803, the installation bracket plate and the printing box 809 are translated along the X-Y axis. At the same time, the printing nozzle 8090 is precisely lifted and lowered in the Z-axis direction under the guidance of the vertical linear rail 804.

[0033] According to Figure 4 andFigure 5 As shown in the figure, inside the longitudinal lead screw rail 803, a vertical line rail 804 is slidably connected through a sliding saddle. Inside the vertical line rail 804, a mounting bracket plate is slidably connected. On the surface of the mounting bracket plate, a resin material box 805 is installed. At the top of the resin material box 805, a feeding end 806 is provided. At the side end of the resin material box 805, a guiding and connecting end 807 is provided. Then, the resin material box 805 is filled with resin material through the feeding end 806.

[0034] According to Figure 5 As shown in the figure, on the surface of the mounting bracket plate, a printing box 809 is installed. At the top of the printing box 809, a connecting injection end 808 is provided. The guiding and connecting end 807 and the connecting injection end 808 are connected through a guiding material pipe. At the same time, it is ensured that the guiding material pipe between the guiding and connecting end 807 and the connecting injection end 808 is unobstructed, preparing sufficient raw materials for the printing process and facilitating the formation of an effective display during the subsequent establishment of the sand table.

[0035] According to Figure 5 As shown in the figure, at the bottom of the printing box 809, a printing nozzle 8090 for automatic angle rotation is installed. On the bottom wall surface of the mounting bracket plate, a high-definition camera end 8091 is installed. So that under the auxiliary monitoring of the high-definition camera end 8091, the printing nozzle 8090 can accurately control the deposition amount and distribution of the resin, layer by layer stacking to construct an object. And the high-definition camera end 8091 can be used to perform real-time photography on the formed model, facilitating the display on the modeling display screen 5. At the same time, during the printing process, the printing nozzle 8090 automatically adjusts the angle according to the complexity of the model, and through automatic angle rotation (electric rotation structure and gear rotation structure) to ensure the printing quality on various inclined surfaces and complex structures, enhancing the stability of the structure and the detail restoration degree.

[0036] According to Figure 1 As shown in the figure, on the side end of the assembly box 1, a double-arm rotating structure 3 is installed. At the bottom of the double-arm rotating structure 3, a telescopic electric push rod 4 is installed. The top of the telescopic electric push rod 4 is connected to the hinged end of the double-arm rotating structure 3. The top of the double-arm rotating structure 3 is connected to a modeling display screen 5. Installing the double-arm rotating structure 3 on the side end of the assembly box 1 and cooperating with the telescopic electric push rod 4 can drive the modeling display screen 5 to have the ability of vertical rotation within a certain range, facilitating the operator to directly view the real-time modeling data and convert it into dynamic deduction while performing tasks during the sand table demonstration.

[0037] According to Figure 1 As shown in the figure, on the left and right ends of the top of the assembly box 1, electric rotating columns 6 are hinged. On the side of the electric rotating columns 6, a cover plate 7 is hinged. At the four ends of the bottom of the assembly box 1, rollers 2 are installed. By using the electric rotating columns 6 equipped on the left and right ends of the top of the assembly box 1, the automatic closing of the cover plate 7 can be realized through electric drive, facilitating the subsequent display of the sand table and the protection of the sand table.

[0038] As shown in Figure 3 At the top center end of the assembly turntable, a weather simulation device 105 is installed. The weather simulation device 105 is used to integrate a water spraying system, a fan, lighting effects, and temperature regulating elements to provide a combined control weather simulation for the prefabricated sand table 104. Through the installed weather simulation device 105, its built-in water spraying system can simulate rainfall, from gentle rain to heavy rain, bringing a moist effect to the landscape on the sand table, testing the waterproof performance of buildings or simulating the water cycle in nature. And the installed fan is used to imitate different wind force conditions from gentle breeze to strong wind, observing the reaction of the sand table model under the action of wind force, which is particularly important for evaluating structural stability. Secondly, by integrating multiple light sources, different lighting conditions can be simulated, including sunlight, moonlight, lightning flashes, etc. This not only enriches the visual experience but also facilitates the study of the impact of lighting on the environment or buildings. Moreover, the temperature regulating element is used to simulate temperature changes from sweltering heat to severe cold through heating or cooling functions, facilitating the testing of the applicability of buildings, vehicles, or the ecosystem (such as whether roads will become congested, etc.).

[0039] The wiring diagrams of the synchronous control motor 802, the drive control motor 903, the real-time three-dimensional scanner 9094, and the weather simulation device 105 in the present invention belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the synchronous control motor 802, the drive control motor 903, the real-time three-dimensional scanner 9094, and the weather simulation device 105 will not be explained in detail.

[0040] Usage method and working principle of this device: First, when conducting assembly sand table operations for territorial spatial planning, the hydraulic scissor lifting frame 11 can be used to steadily lift the stabilizing plate 12, the dynamic detection and adjustment component 9, and the sand table module adjustment component 10. The electric rotating columns 6 installed at the left and right ends of the top of the assembly box 1 can drive the opening of the cover plate 7 through electric power, facilitating the subsequent display of the sand table. Then, the power supply can be connected to make the main drive angle motor start working, driving the assembly turntable inside the main rotating groove plate 101 to rotate slowly and steadily. With the four quick assembly installation grooves 102, the staff can quickly insert different assembled sand tables 104 in place. Each installation groove is designed with a quick installation structure to ensure that the assembled sand table 104 can be quickly installed inside the rotating groove rail plate 103, making the installation simple and fast. When the assembled sand table 104 is installed, the secondary rotating motor starts. The secondary rotating motors are respectively located at the bottoms of the four rotating groove rail plates 103 and can work independently or cooperatively according to the instructions of the external logic controller, enabling each rotating groove rail plate 103 and the sand table module on it to perform their respective rotating operations. At the same time, the rotation of the main rotating groove plate 101 and the rotation of the assembled sand table 104 driven by the secondary rotating motor form two operation modes. The specific mode one is that the main drive angle motor drives the assembly turntable and the entire sand table to rotate, so that the four assembled sand tables 104 installed can each form a sand table display of the four seasons. The specific mode two is that the above-mentioned secondary rotating motor drives the assembled sand table 104 to rotate independently, which can be located below the printing nozzle 8090, facilitating the formation of real-time adjustment of the sand table model, realizing the high dynamic and personalized customization of the display scene, enhancing the interactivity and expressiveness of the display. And during the above operation process, through the installed weather simulation device 105, its built-in water spraying system can simulate rainfall, from gentle rain to heavy rain, bringing a moist effect to the landscape on the sand table, testing the waterproof performance of buildings or simulating the water cycle in nature, and imitating different wind force conditions from gentle breeze to strong wind through the installed fans to observe the reaction of the sand table model under the action of wind force, which is particularly important for evaluating structural stability. Secondly, integrating multiple light sources can simulate different lighting conditions, including sunlight, moonlight, lightning flashes, etc. This not only enriches the visual experience but also facilitates the study of the impact of lighting on the environment or buildings. And, using the temperature adjustment element, through heating or cooling functions, it can simulate temperature changes from sweltering heat to severe cold, facilitating the testing of the usability of buildings, vehicles, or ecosystems. At the same time, the synchronous control motor 802 can be used to drive the horizontal linear rail 801 and the longitudinal screw rail 803, making the installation bracket plate and the printing box 809 translate along the X-Y axis. At the same time, the printing nozzle 8090 performs precise lifting in the Z-axis direction under the guidance of the vertical linear rail 804, enabling the printing nozzle 8090 to accurately control the deposition amount and distribution of the resin under the auxiliary monitoring of the high-definition camera end 8091, and stacking objects layer by layer.Moreover, the high-definition camera 8091 can be used to capture real-time images of the formed model, which is convenient for display on the modeling display screen 5. Meanwhile, during the printing process, the printing nozzle 8090 automatically adjusts its angle according to the complexity of the model, and rotates automatically to ensure the printing quality on various inclined surfaces and complex structures, enhancing the structural stability and detail restoration. Secondly, after receiving the control signal from the external logic controller, the chip driver board 9092 sends a new control instruction to the transmission control motor 903, causing the transmission control motor 903 to start after receiving the drive signal. The large gear 904 connected to its output end rotates accordingly. The rotation of the large gear 904 is transmitted to the synchronous shaft 906 through the chain gear 905. When the engagement of the chain gear 905 and the large gear 904 drives the synchronous shaft 906 to rotate, the first bevel gear 907 and the second bevel gear 908 on the synchronous shaft 906 are engaged with each other, thereby effectively adjusting the rotation direction of the connecting transmission short shaft 9090 and reducing speed and increasing torque, causing the connecting transmission short shaft 9090 to drive the inner rotating frame 9091 to rotate inside the outer rotating frame 909. Moreover, the outer rotating frame 909 can rotate synchronously under the cooperation of the side rotating track shaft column 9093, enabling the relative synchronous adjustment formed by the outer rotating frame 909 and the inner rotating frame 9091. Thus, it realizes driving the real-time 3D scanner 9094 to perform omnidirectional processing and analysis scanning on the materials printed in the assembled sand table 104 in the three-dimensional space, and transporting them to the modeling display screen 5. And the double-arm rotating structure 3 is installed at the side end of the assembly box 1, cooperating with the telescopic electric push rod 4, which can drive the modeling display screen 5 to form a vertical rotation ability within a certain range, facilitating the operator to intuitively view the real-time modeling data and convert it into dynamic deduction while performing tasks during the sand table demonstration.

A real-time three-dimensional scanner (9094) is installed at the axial center end of the chip driving board (9092); The sand table module adjustment component (10) includes a main rotating groove disk (101). A main driving angle motor is installed at the axial center of the bottom of the main rotating groove disk (101). An assembly turntable is rotatably connected inside the main rotating groove disk (101). Four groups of quick assembly installation grooves (102) are equally arranged on the top wall surface of the assembly turntable. A rotating groove rail disk (103) is installed on the inner surface of the four groups of quick assembly installation grooves (102); A printing nozzle (8090) for automatic angle rotation is installed at the bottom of the printing box (809). A high-definition camera end (8091) is installed on the bottom wall surface of the installation bracket plate. The printing nozzle (8090) accurately controls the deposition amount and distribution of the resin under the auxiliary monitoring of the high-definition camera end (8091), and builds objects layer by layer. The high-definition camera end (8091) is used to perform real-time photography on the formed model and display it on the modeling display screen (5). At the same time, during the printing process, the printing nozzle (8090) automatically adjusts the angle according to the complexity of the model, and rotates automatically to ensure the printing quality on inclined surfaces and complex structures, enhancing the structural stability and detail restoration; Inside the rotating groove track plate (103), an assembled sand table (104) is rotatably connected. At the bottom of the rotating groove track plate (103), a secondary rotating motor is installed. The secondary rotating motor is installed in the surface grooves of the four quick-assembly installation grooves (102). When the assembled sand table (104) is installed, the secondary rotating motor starts. The secondary rotating motors are respectively located at the bottoms of the four rotating groove track plates (103) and can work independently or cooperatively according to the instructions of an external logic controller, enabling each rotating groove track plate (103) and the sand table module thereon to perform their respective rotating operations. At the same time, the rotation of the main rotating groove plate (101) and the rotation of the assembled sand table (104) driven by the secondary rotating motor form two working modes. The specific mode one is that the main driving angle motor drives the assembly turntable and the entire sand table to rotate, so that the four installed assembled sand tables (104) can each form a sand table display of the four seasons. The specific mode two is that the secondary rotating motor drives the assembled sand table (104) to rotate independently. It can be located below the printing nozzle (8090) to facilitate real-time adjustment of the sand table model; The multi-dimensional printing component (8) includes two groups of horizontal guide rails (801).
