Description

Technical Field

[0001] This invention relates to the field of training equipment technology, and in particular to an immersive research and training platform for national defense education. Background Technology

[0002] Immersive learning and training platforms for national defense education are core training equipment for youth learning and national defense science education. Primarily relying on sand table simulations of military scenarios, they provide immersive practical teaching, allowing trainees to intuitively understand military layouts, combat scenarios, and other national defense knowledge. Compared to traditional text and video teaching, they offer stronger hands-on experience and a more immersive learning environment, and are currently widely used in primary and secondary school national defense learning programs, science museums, and military training bases. However, similar national defense sand table training equipment on the market still suffers from numerous technical defects and usage pain points in practical applications, seriously affecting the effectiveness of training and teaching, as well as the safety and lifespan of the equipment.

[0003] First, traditional training sand tables are difficult to clean and maintain. Most existing equipment only offers static display or simple rotating display functions. With the sand tables exposed to the elements for extended periods, dust and debris easily accumulate during training. Manual wiping is not only inefficient but also easily damages the surface texture, compromising the accuracy of military scenario simulations. Furthermore, manual cleaning has blind spots, failing to achieve comprehensive cleaning. Long-term accumulation of grime significantly reduces the sand table's display effect, impacting the immersive training experience. Second, there are significant safety hazards during equipment operation. Traditional rotating sand table equipment lacks a linkage locking structure. During cleaning and training operations, accidental activation of control switches or loosening of the transmission structure can easily cause the sand table to overturn and rotate unexpectedly. This not only causes damage to the sand table and structural misalignment but also poses a significant safety hazard, easily resulting in scratches and injuries to on-site operators.

[0004] Meanwhile, existing equipment lacks waterproofing and drying protection. Most sand table training equipment does not have a dedicated waterproof isolation structure. If water spraying is used for cleaning, water mist will splash everywhere, seeping into the core internal structures such as motors, transmission gears, and hydraulic components. Long-term water accumulation and dampness can cause component corrosion, short circuits, transmission jams, and other malfunctions, significantly shortening the equipment's lifespan. Moreover, sand tables left with a large amount of water stains and moisture after water spraying are slow to air dry, easily leading to mold, deformation, and cracking of the sand table material, making it impossible to quickly reuse for secondary training and resulting in poor equipment operation continuity. In addition, traditional equipment training scenarios are limited, only providing static displays and unable to simulate dynamic military confrontations, environmental changes, or other immersive scenarios. The training lacks interest and realism, failing to meet the current teaching needs of immersive research and learning training in national defense, and hindering the improvement of the teaching quality of national defense science popularization training. Summary of the Invention

[0005] Purpose of the Invention: The purpose of this invention is to solve the problems of low cleaning efficiency and incomplete cleaning of existing national defense training sand tables, as well as the risk of damage to the sand table due to manual cleaning. By setting up a linkage cross-spray water cleaning structure, the sand table can be automatically cleaned in all directions, replacing manual cleaning operations, improving the cleaning efficiency and cleanliness of the sand table, ensuring the display effect of the military scene of the sand table, and maintaining an immersive training experience. Another purpose of this invention is to achieve equipment operation to prevent accidental touch locking, automatic waterproof isolation, and rapid drying and dehumidification, avoiding the risk of equipment damage and personnel injury, extending the service life of the equipment, and ensuring the continuous and stable operation of the equipment.

[0006] Technical solution: A national defense education immersive study and training platform includes a fixed platform. A rotating groove is formed on the upper surface of the fixed platform. A motor is fixedly connected to the outer wall of the rotating groove. A rotating rod is fixedly connected to the output end of the motor. The output end of the rotating rod extends through the outer wall of the fixed platform. A support plate is fixedly connected to the outer wall of the rotating rod.

[0007] Furthermore, the lower inner surface of the fixed platform has multiple swivel openings, each swivel opening having a hollow tube rotatably connected inside. The rear surface of the fixed platform is fixedly connected to a water storage cavity. The rear ends of the hollow tubes extend to the outer side wall of the fixed platform and are rotatably connected to cavities.

[0008] Furthermore, the hollow tubes are arranged in pairs. A gear is fixedly connected to the front end of one hollow tube, and a half gear is fixedly connected to the front end of the other hollow tube. The gear and the half gear are meshed together. A hydraulic chamber is fixedly connected to the outer wall of the fixed platform. A second motor is fixedly connected to the front surface of the hydraulic chamber. The output end of the second motor extends into the interior of the hydraulic chamber and is fixedly connected to a cam. A sliding frame is slidably connected inside the hydraulic chamber, and the inner side wall of the sliding frame contacts the cam.

[0009] Furthermore, the outer wall of the fixed platform is symmetrically and fixedly connected with sliding cavities, and a sliding plate is slidably connected inside the sliding cavity. A rack is fixedly connected to the lower surface of the sliding plate. A transmission wheel one is rotatably connected to the outer wall of the fixed platform, and a transmission wheel two is fixedly connected to the front surface of the half gear. A transmission belt one is wound between the outer walls of the transmission wheel one and the transmission wheel two. The outer wall of the transmission wheel one has toothed grooves. The rack is meshed with adjacent toothed grooves. The outer wall of the hydraulic cavity is symmetrically and fixedly connected with liquid outlet pipes, and the liquid outlet pipes are fixedly connected to different sliding cavities respectively.

[0010] Furthermore, a limiting ring is fixedly connected to the front end of the rotating rod, and locking holes are symmetrically opened on the outer side wall of the limiting ring. A spring cavity is symmetrically fixedly connected to the outer side wall of the fixed platform. A vertical plate is slidably connected inside the spring cavity. Locking rods are fixedly connected to the opposite sides of the vertical plate. The locking rods are engaged with the inside of the locking holes. A spring is fixedly connected between the vertical plate and the inner side wall of the spring cavity. The right side of the spring cavity is fixedly connected to the limiting cavity.

[0011] Furthermore, a turntable is rotatably connected inside the limiting cavity. Multiple sliding grooves are provided on the outer side wall of the turntable, and abutments are slidably connected inside each of the sliding grooves. A vertical column is fixedly connected to the front surface of the turntable. The front end of the vertical column extends through to the outside of the limiting cavity and is fixedly connected to a transmission wheel three. A transmission wheel four is fixedly connected to the rear end of the output end of the motor two. A transmission belt two is wound around the outer side walls of the transmission wheel three and the transmission wheel four.

[0012] Furthermore, an outer cavity is fixedly connected to the outer wall of the fixed platform, and a baffle is rotatably connected inside the outer cavity. A horizontal column is fixedly connected to the outer wall of the baffle, and the ends of the horizontal column extend to the outer side of the outer cavity. A torsion spring is wound around the horizontal column on the outer wall of the outer cavity.

[0013] Furthermore, multiple fan chambers are fixedly connected to the outer side wall of the outer cavity, multiple heating tubes are fixedly connected to the inner side wall of the outer cavity, and multiple support rods are symmetrically fixedly connected to the outer side wall of the fixed platform.

[0014] Beneficial Effects: During operation, the hydraulic transmission structure driven by motor 2 utilizes the reciprocating compression of hydraulic oil to achieve the reciprocating movement of the slide plate and rack. Combined with the alternating reverse meshing of gears and half-gears, this drives two sets of hollow tubes to swing alternately in opposite directions, creating a cross-spraying effect from the water nozzles. This dynamic cross-spraying mode can comprehensively cover the surface and crevices of the sand table. Compared to single-direction spraying, it provides a wider cleaning coverage and more uniform water impact, thoroughly removing dust, debris, and residual stains from the sand table surface, eliminating blind spots. Simultaneously, the equipment can be used with motor 1 to rotate the sand table. The dynamically rotating sand table combined with the cross-spraying structure further enhances the comprehensiveness of cleaning. No manual wiping is required throughout the process, completely avoiding surface wear and texture damage caused by uneven manual cleaning. This effectively protects the accuracy of the military scene simulation, significantly improves the automation level and cleaning quality of the sand table cleaning operation, and ensures that the national defense training sand table maintains a clear and complete display effect for a long time, stably supporting immersive research and training work. During the water spraying and cleaning training operation, motor two runs continuously, driving the turntable to rotate at high speed via transmission wheels three and four and transmission belt two. Centrifugal force throws the blocks inside the chute outwards, creating a physical barrier on the outside of the spring cavity, limiting the compression displacement of the vertical plate and spring. This ensures the locking rod is stably engaged in the locking hole of the limit ring, achieving rigid locking and fixation between the rotating rod and the sand table. This structure keeps the sand table absolutely fixed throughout the entire operation, preventing accidental flipping of the sand table due to accidental contact with motor one or the transmission structure during manual cleaning or equipment operation. It avoids damage to the equipment structure and detachment of the scene model caused by sand table flipping and impact, and effectively prevents operators from being scratched or injured by the rotating sand table, comprehensively ensuring the safety of both equipment and personnel. When the equipment stops spraying water, motor two stops, the centrifugal force of the turntable disappears, the blocks automatically retract and reset, and the spring releases its elasticity, causing the locking rod to disengage from the locking hole, quickly releasing the lock and restoring the sand table to its normal rotation and display function. The entire locking mechanism operates in conjunction with the original power system of the equipment, without the need for additional control switches. It has a high degree of automation, stable operating logic, and no need for manual locking and unlocking, making it suitable for the routine training and operation needs of the equipment. The equipment utilizes an external cavity, a flip-up baffle, and a torsion spring to form an automatic waterproof structure. Under normal conditions, the torsion spring closes the baffle, creating a sealed waterproof cavity. This effectively prevents water mist from splashing during water spray cleaning, avoiding water penetration into core components such as the motor, gears, hydraulic components, and transmission structure. This eliminates malfunctions such as component corrosion, short circuits, and transmission jamming, protecting the internal structure from the source and significantly extending the overall lifespan of the equipment. Simultaneously, addressing the issue of residual water stains and dampness on the sand table after water spray cleaning, the equipment incorporates a combined heating element and fan cavity drying mechanism. Upon activating the drying mode, the heating element rapidly heats the air within the cavity, while the high-speed fan creates circulating hot air. The airflow automatically opens the baffle, allowing hot air to fully cover the surface and crevices of the sand table, quickly removing residual moisture for efficient drying and dehumidification. After drying, the torsion spring automatically resets and closes the baffle, restoring the waterproof protection. This structure can quickly dry the sand table, solving the problems of long drying time and easy mold and deformation of traditional sand tables. It allows the sand table to be quickly put into secondary training use, effectively improving the continuity of equipment operation and training efficiency. At the same time, it achieves dual protection of waterproofing and drying, making it suitable for long-term and high-frequency national defense research and training operation scenarios.

Detailed Implementation

[0017] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0018] like Figures 1-8As shown, a national defense education immersive study and training platform is provided, including a fixed platform 1. A rotating groove 2 is formed on the upper surface of the fixed platform 1. A motor 3 is fixedly connected to the outer wall of the rotating groove 2. A rotating rod 4 is fixedly connected to the output end of the motor 3. The output end of the rotating rod 4 extends through the outer wall of the fixed platform 1. A support plate 5 is fixedly connected to the outer wall of the rotating rod 4. A display sand table 6 is provided on the lower surface of the support plate 5. Multiple rotating openings 7 are formed on the lower inner surface of the fixed platform 1. Hollow tubes 8 are rotatably connected inside each rotating opening 7. A water storage cavity 9 is fixedly connected to the rear surface of the fixed platform 1. The rear ends of the hollow tubes 8 extend to the outer wall of the fixed platform 1 and are rotatably connected to a cavity 10. A vertical tube 11 is fixedly connected to the top of the cavity 10, and the top of the vertical tube 11 is fixedly connected to the water storage cavity 9. A water storage cavity 12 is opened on the lower inner surface of the fixed platform 1, and a water outlet 13 is opened on the lower inner surface of the water storage cavity 12. Multiple water spray heads 14 are fixedly connected to the outer wall of the hollow tubes 8. Two hollow tubes 8 are grouped together. A gear 15 is fixedly connected to the front end of the hollow tube 8. A half-gear 16 is fixedly connected to the front end of a hollow tube 8. Gear 15 and half-gear 16 are meshed together. A hydraulic chamber 17 is fixedly connected to the outer wall of the fixed platform 1. A motor 18 is fixedly connected to the front surface of the hydraulic chamber 17. The output end of the motor 18 extends into the interior of the hydraulic chamber 17 and is fixedly connected to a cam 20. A slide frame 21 is slidably connected inside the hydraulic chamber 17. The inner side wall of the slide frame 21 contacts the cam 20. Slide cavities 22 are symmetrically fixedly connected to the outer wall of the fixed platform 1. The slide cavities 22 are slidably connected inside the slide frame 22. A slide plate 23 is attached, and a rack 24 is fixedly connected to the lower surface of the slide plate 23. A transmission wheel 25 is rotatably connected to the outer side wall of the fixed platform 1. A transmission wheel 26 is fixedly connected to the front surface of the half gear 16. A transmission belt 27 is wound between the outer side walls of the transmission wheel 25 and the transmission wheel 26. The outer side wall of the transmission wheel 25 has a toothed groove 28. The rack 24 is meshed with the adjacent toothed groove 28. The outer side wall of the hydraulic chamber 17 is symmetrically connected to the outlet pipe 29. The outlet pipe 29 is fixedly connected to different slide chambers 22 respectively. First, the equipment's water supply system is turned on. The water storage chamber 9 supplies water to each set of hollow tubes 8 through the vertical pipe 11 and the cavity 10. After the water fills the hollow tubes 8, multiple spray nozzles 14 connected to its outer wall are ready to spray water. At the same time, the water storage chamber 12 and the water outlet 13 are ready to collect accumulated water to ensure the equipment's circulating operation. After the water supply is ready, the motor 18 connected to the hydraulic chamber 17 is started. The output end of the motor 18 drives the internal cam 20 to rotate continuously. During the rotation of the cam 20, it continuously squeezes the sliding frame 21, causing the sliding frame 21 to slide back and forth inside the hydraulic chamber 17, squeezing the hydraulic oil inside the hydraulic chamber 17. Under the pressure, the outlet pipes 29 connected to both sides of the hydraulic chamber 17 alternately supply and return oil, transmitting hydraulic power to the symmetrically arranged sliding cavities 22 on both sides, realizing the core power output effect of the hydraulic chamber squeezing left and right. Under the action of hydraulic thrust, the sliding plate 23 inside the sliding cavity 22 slides back and forth, simultaneously driving the rack 24 fixed at the bottom of the sliding plate 23 to move back and forth. The rack 24 meshes with the toothed groove 28 on the outer side of the transmission wheel 25, thereby driving the transmission wheel 25 to rotate alternately in both directions. Through the transmission belt 27, the transmission wheel 25 drives the transmission wheel 26 to rotate synchronously, ultimately driving the half gear 16 fixed to the transmission wheel 26 to rotate continuously. At this time, the equipment activates the meshing linkage mechanism of gear 15 and half gear 16. Each set of two hollow tubes 8 is equipped with gear 15 and half gear 16 respectively, and the reciprocating half gear 16 continuously meshes with gear 15 alternately. During the meshing process, gear 15 and half gear 16 always rotate in opposite directions, driving the two sets of hollow tubes 8 to rotate and swing back and forth in the rotating opening 7 at opposite angles and alternating amplitudes. Finally, the hollow tubes 8 swinging in opposite directions drive the water spray head 14 on the tube wall to swing bidirectionally, and the sprayed water flows converge and intersect, stably achieving the training effect of cross-spraying water. At the same time, the equipment can start motor 3, which drives the support plate 5 and the bottom display sand table 6 to rotate through the rotating rod 4, realizing the sand table cleaning function.

[0019] In this embodiment, a limit ring 30 is fixedly connected to the front end of the rotating rod 4. Locking holes 31 are symmetrically provided on the outer side wall of the limit ring 30. Spring cavities 32 are symmetrically fixedly connected to the outer side wall of the fixed platform 1. A vertical plate 33 is slidably connected inside the spring cavity 32. Locking rods 34 are fixedly connected to opposite sides of the vertical plate 33. The locking rods 34 are engaged with the inside of the locking holes 31. Springs 50 are fixedly connected between the vertical plate 33 and the inner side wall of the spring cavity 32. A limit ring 30 is fixedly connected to the right side of the right spring cavity 32. The positioning cavity 35 is rotatably connected to a turntable 36. The outer side wall of the turntable 36 is provided with multiple sliding grooves 37. Each sliding groove 37 is slidably connected to a stop block 38. The front surface of the turntable 36 is fixedly connected to a vertical column 39. The front end of the vertical column 39 extends to the outside of the positioning cavity 35 and is fixedly connected to a transmission wheel 40. The rear end of the output end of the motor 18 is fixedly connected to a transmission wheel 41. The outer side walls of the transmission wheel 40 and the transmission wheel 41 are wound with a transmission belt 42. During routine training operations on the platform, motor 2 18 runs continuously, and its output end drives transmission wheel 41 to rotate synchronously. Through transmission belt 2 42, transmission wheel 3 40 rotates, causing the vertical column 39 to drive the turntable 36 inside the limiting cavity 35 to rotate at high speed. During the rotation of the turntable 36, centrifugal force is used to throw the abutment block 38 inside the slide groove 37 outward. The extended abutment block 38 can block and limit the outside of the spring cavity 32. At this time, the vertical plate 33 inside the spring cavity 32 is limited by the outer abutment block 38 and cannot compress the spring 50 inward or outward. The locking rod 34 remains engaged and is locked into the locking hole 31 of the limiting ring 30. The rotating rod 4 cannot drive the support plate 5 and the display sand table 6 to rotate freely, so that they cannot be rotated during cleaning to prevent accidental contact. When the equipment ends the water spray cleaning mode, motor 2 18 stops running, and the turntable 36 stops rotating. The centrifugal force completely disappears, and the abutment block 38 that was thrown out retracts and resets, releasing the blocking and limiting effect on the outside of the spring cavity 32. After the limit is released, the spring 50, which is under compression inside the spring cavity 32, releases its elastic thrust, directly pushing the vertical plate 33, which is slidably connected inside the spring cavity 32, to move rapidly inward. The two vertical plates 33 move inward simultaneously, causing the locking rod 34 fixed inside to disengage from the locking hole 31. This allows the support plate 5 and the display sand table 6 at the bottom to rotate, providing an anti-accidental contact function. The entire mechanism relies on the centrifugal force generated by the start and stop of motor 18 to achieve automatic locking, ensuring reliable and stable operation. Throughout the cleaning process, the sand table remains fixed and locked, effectively preventing accidental rotation caused by accidental activation of motor 3 or the transmission structure during manual cleaning, thus avoiding equipment damage and personnel injury. After the cleaning operation is completed, turning off motor 18 releases the lock, restoring the normal rotation and display function of the sand table.

[0020] In this embodiment, an outer cavity 43 is fixedly connected to the outer wall of the fixed platform 1, a baffle 44 is rotatably connected inside the outer cavity 43, a horizontal column 45 is fixedly connected to the outer wall of the baffle 44, the ends of the horizontal column 45 extend to the outer side of the outer cavity 43, a torsion spring 46 is wound around the horizontal column 45 on the outer wall of the outer cavity 43, a plurality of fan cavities 47 are fixedly connected to the outer wall of the outer cavity 43, a plurality of heating tubes 48 are fixedly connected to the inner wall of the outer cavity 43, and a plurality of support rods 49 are symmetrically fixedly connected to the outer wall of the fixed platform 1. During the sand table water spraying cleaning process, the baffle 44 inside the fixed platform 1 serves as a basic waterproof isolation, preventing water mist from the spray head 14 from splashing everywhere. The horizontal column 45 fixed on the outside of the baffle 44 penetrates the outer cavity 43, and a torsion spring 46 is wound around the outside. Under normal conditions, the torsion spring 46 remains in an elastic return state, driving the baffle 44 to close and block the inner space of the outer cavity 43, forming a sealed waterproof cavity, effectively preventing water mist from seeping into the equipment, and achieving full-process waterproof protection. When a large amount of water stains remain on the surface of the sand table and need to be dried, the equipment starts the drying mode. First, the multiple sets of heating tubes 48 installed on the inner wall of the outer cavity 43 are turned on. After the heating tubes 48 are powered on, they heat up rapidly, heating the air inside the outer cavity 43 to create a constant warm air environment. Simultaneously, multiple fan chambers 47 fixed to the outside of the outer cavity 43 are activated. The fans inside the fan chambers 47 operate at high speed, continuously supplying airflow into the outer cavity 43, accelerating the circulation of hot air. Under the thrust of the fan airflow, the baffle 44 can be blown open, ensuring uniform diffusion of hot air and allowing the flowing warm air to blow across the surface of the display sand table 6 from all directions, quickly removing residual moisture from the surface and crevices of the sand table, achieving efficient drying and dehumidification. Throughout the drying process, multiple support rods 49 symmetrically arranged on the outside of the fixed platform 1 provide stable support for the overall drying mechanism, ensuring the stable operation of components such as the outer cavity 43 and fan chambers 47, and preventing shaking or displacement during operation. After the operation is completed, the heating tube 48 and fan chambers 47 are turned off, the torsion spring 46 automatically resets, and the baffle 44 closes again, restoring the equipment to a waterproof and protective state. This not only solves the problem of damp water accumulation in the sand table after water spraying but also provides long-term protection for the internal structure of the equipment, extending its service life.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
