DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention provides three technical solutions, including the following embodiments: Example 1

[0034] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 A sand table device for national land space planning includes a square box 1, the top of the square box 1 is an open design, a four-way rotating erection mechanism 2 is arranged on the bottom wall of the square box 1, a sand table 3 is arranged above the four-way rotating erection mechanism 2, the top of the sand table 3 is an open design, and the inside of the sand table 3 is provided with materials for space planning such as mud, models, and war chess. The four-way rotating erection mechanism 2 controls the sand table 3 to rotate and stand up forward, backward, left, and right. According to needs, the sand table 3 can be controlled to flip forward, backward, left, and right.

[0035] The four-way rotating erecting mechanism 2 includes a mounting frame 21 fixed on the bottom wall of the square box 1, and a universal shaft 22 is rotatably connected to the mounting frame 21. A motor 23 is arranged on one side of the universal shaft 22. The motor 23 is controlled by an external switch and electrically connected to an external power supply. The motor 23 drives the universal shaft 22 to rotate. A rotating rod 24 is fixed to the universal shaft 22, and one end of the rotating rod 24 is rotatably connected to two rotating arms 26 through a pin shaft 25. A flap 27 is arranged on the top of the mounting frame 21, and the top ends of the two rotating arms 26 are rotatably connected to the bottom of the flap 27 through a universal shaft 28. The setting of the universal shaft 22 and the universal shaft 28 can control the flap 27 to flip forward, backward, left and right. Four connecting columns 29 are fixed to the bottom of the flap 27, and four fixing seats 210 are fixed to the top of the mounting frame 21. A groove 211 is provided on the top, and four connecting columns 29 are located inside the groove 211. The size of the connecting column 29 is adapted to that of the groove 211. A mounting seat 212 is fixed on one side of the four fixing seats 210, and a cylinder 213 is fixed on the four mounting seats 212. A limit lock plate 214 is fixed on the output end of the four cylinders 213. The four cylinders 213 are controlled by an external switch. When the flap 27 needs to be flipped to a certain side, the corresponding cylinder 213 is started so that the cylinder 213 pushes the limit lock plate 214 through the mounting seat 212 to block the locking connecting column 29. The bottom of the limit lock plate 214 contacts the top of the connecting column 29, and the connecting column 29 can be flipped in that direction. The four cylinders 213 are initially in a locked state. When flipping is required, three cylinders 213 are closed to unlock the three connecting columns 29.

[0036] By setting up the four-way rotating erecting mechanism 2, the sand table 3 can be flipped and erected in four opposite directions, front, back, left and right. When the sand table 3 is lifted to a suitable height and locked at any desired angle, the staff can get rid of the constraints of traditional bending over work and carry out detailed planning and meticulous adjustments in a more comfortable and natural standing posture. Such a design is of great significance, especially for the sand table models with large volume and intricate details. It makes even the central core area of ​​the sand table easily accessible, and planning operations are no longer restricted. Every inch of land and every layout can be accurately considered.

[0037] In addition, standing up the sand table model and rotating it to the best display angle greatly enhances its appeal and interactivity as a display tool. In conferences, exhibitions, or teaching, this function allows the sand table model to be presented to people around from multiple perspectives. Whether it is a macro overview from the front or an in-depth analysis from the side, it can be seen at a glance. Without moving, you can fully appreciate the rich information and design concepts carried by the sand table. This multi-angle and highly interactive display method not only deepens the audience's understanding of the planning content, but also stimulates more discussions and inspiration collisions, providing a more comprehensive and intuitive reference for planning decisions.

[0038] Four upright poles 4 are fixed to the bottom of the sandbox 3 , and the bottom ends of the four upright poles 4 are fixed to the top of the flap 27 .

[0039] A mud collecting assembly 7 is provided at the bottom of the square box 1. The mud collecting assembly 7 includes two vertical plates 71 fixed at the bottom of the square box 1. Slide grooves 72 are provided on the opposite sides of the two vertical plates 71. A mud collecting box 73 is slidably connected between the opposite sides of the two vertical plates 71. The mud collecting box 73 is used to collect fallen mud and models.

[0040] Cross bars 74 are fixed on both sides of the mud collecting box 73 . The two cross bars 74 are both located inside the slide groove 72 . The outer surfaces of the two cross bars 74 are slidably connected to the inner surface of the slide groove 72 . A handle 75 is fixed on one side of the mud collecting box 73 . Example 2

[0041] Based on Example 1, see Figure 1 , Figure 3 , Figure 6 , Figure 7 As shown, a quick mud shoveling assembly 5 for cleaning mud and models is provided on the sandbox 3. The quick mud shoveling assembly 5 includes a horizontal plate 51 fixed on the top of the flap 27. A cylinder 2 52 is fixed on the top of the horizontal plate 51. A movable plate 53 is fixed on the output end of the cylinder 2 52. The cylinder 2 52 is controlled by an external switch and is electrically connected to an external power supply.

[0042] Two inclined grooves 54 are formed through one side of the moving plate 53 . Moving rods 55 are slidably connected to the inner surfaces of the two inclined grooves 54 . A U-shaped clamp 56 is fixed to one end of the two moving rods 55 .

[0043] Two U-shaped clips 56 are placed on the side walls of the sand table 3 and slide on the side walls of the sand table 3. Two triangular push blocks 57 are slidably connected to the bottom wall of the sand table 3. The inclined surfaces of the triangular push blocks 57 are in contact and squeezed with the mud, sand and models, and finally the mud, sand and models are squeezed out of the sand table 3, so as to achieve rapid cleaning and re-planning. One side of the two U-shaped clips 56 is fixed to the top of the triangular push blocks 57.

[0044] By setting the quick mud shoveling component 5, after the sand table 3 is flipped and lifted to a vertical state, the two triangular push blocks 57 are moved in opposite directions to squeeze the mud and models in the sand table 3 and shovel them out of the sand table 3. When it is necessary to re-plan a new sand table 3, the mud and models can be quickly removed in time. By setting the mud collecting component 7, the fallen mud and models can be collected in time. The setting of the quick mud shoveling component 5 saves cleaning time and significantly improves work efficiency, allowing planners to focus more on the conception and realization of creativity rather than tedious cleaning work. Example 3

[0045] Based on Example 2, see Figure 1-Figure 2As shown, a spraying unit 6 for spraying water on the mud and sand in the sandbox 3 is arranged between the square box 1 and the U-shaped clamp 56. The spraying unit 6 includes a water tank 61 fixed on both sides of the square box 1. The water tank 61 stores clean water. The tops of the two water tanks 61 are connected to a water inlet pipe 62, and external clean water is introduced into the water tank 61 through the water inlet pipe 62.

[0046] A water pump 63 is fixed on the top of the two water tanks 61. The water pump 63 is controlled by an external switch and electrically connected to an external power supply. The water outlets of the two water pumps 63 are connected to a curved pipe 64, which is specifically a rubber hose. The water pump 63 can pump water in the water tank 61 into the curved pipe 64. A pipe sleeve 65 is fixed on the top of the two U-shaped clamps 56.

[0047] The interiors of the two pipe sleeves 65 are both rotatably connected with vertical pipes 66. The vertical pipes 66 rotate in the pipe sleeves 65, and the angle of the nozzle 67 can be flexibly adjusted, thereby adjusting the angle of the water mist spraying. One side of the two vertical pipes 66 is connected to one end of the curved pipe 64. One side of the two vertical pipes 66 is connected to the nozzle 67. The nozzle 67 is controlled by an external switch and is electrically connected to an external power supply. After the nozzle 67 is started, it can spray clean water in the form of mist, and spray the water mist onto the mud and sand to achieve dust reduction.

[0048] Through the setting of the spraying unit 6, when the mud and the model are shoveled out of the sand tray 3, the water mist is sprayed by starting the nozzle 67. At the same time, the nozzle 67 moves with the U-shaped clamp 56, and the mud in the sand tray 3 can be sprinkled with water in time to achieve dust reduction operation, thereby avoiding the flying mud and sand from polluting the surrounding environment. When executing the key link of shoveling the mud and the model out of the sand tray 3, once the mud shoveling operation is started, the spraying unit 6 responds immediately and sprays water mist, which curbs the flying of dust at the source.

[0049] The nozzle 67 is not fixed, but connected to the U-shaped clamp 56. With its flexible movement trajectory, it weaves a dense dust suppression net above the sand table 3. This dynamic watering method ensures that every corner of the sand table 3 can be evenly and effectively moistened.

[0050] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0051] During operation, when the sand table 3 needs to be displayed at multiple angles, one of the four directions of front, back, left, and right can be selected to stand up according to the needs of the crowd, and the cylinder 1 213 in the direction is started to make the cylinder 1 213 push the limit lock plate 214 to lock the connecting column 29 in the groove 211, and the motor 23 is started at the same time, so that the motor 23 drives the universal shaft 1 22 to rotate, and then drives the rotating rod 24 and the rotating arm 26 to rotate and stretch upward, and then drives the flap 27 to flip around the locked connecting column 29, flipping the sand table 3 to tilt or even flip it to a vertical state. Flipping it to a vertical state is convenient for planning operations, and during the flipping process, it can be displayed to people around at multiple angles. When the sand table 3 needs to be replanned, After the sand table 3 is flipped to a vertical state, cylinder 2 52 is started, so that cylinder 2 52 drives the moving plate 53 to move upward, and at the same time, the moving plate 53 drives the two moving rods 55 to move toward each other, and at the same time, the moving rods 55 drive the two U-shaped clamps 56 and the triangular push blocks 57 to move toward each other, and then the two triangular push blocks 57 squeeze the mud and sand models in the sand table 3 out of the sand table 3, open the mud collecting box 73, and collect the fallen mud and sand and models. In order to prevent the dry mud and sand from flying in this process, when the triangular push blocks 57 move toward each other, the two water pumps 63 and the nozzle 67 are started, and the water in the water tank 61 is sprayed into the sand table 3 through the nozzle 67 to reduce the dust of the mud and sand. By rotating the vertical pipe 66, the angle of the nozzle 67 can be flexibly adjusted.

[0052] The embodiments of the invention are described in detail above, but the contents are only preferred embodiments of the invention and cannot be considered to limit the scope of implementation of the invention. All equivalent changes and improvements made according to the scope of application of the invention should still fall within the scope of the patent coverage of the invention.
