[0011] As a preferred solution, a separation component is provided in the installation cavity, and the separation component is used to release the lock between the installation rod and the machine body, so that the float and the installation rod are separated from the machine body.

[0012] As a preferred solution, the separation assembly includes a floating plate and a trapezoidal plate fixedly installed on the upper surface of the floating plate, a fixed plate is fixedly sleeved on the spring rod, a second inclined plate is fixedly installed on the bottom end of the fixed plate, a socket is opened on the upper surface of the mounting rod, the trapezoidal plate sliding seal is inserted in the socket, and the inclined surface is arranged face to face with the inclined surface of the second inclined plate, a sliding rod is vertically fixedly installed in the mounting cavity, and the floating plate is slidably sleeved on the sliding rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The device consists of a base, a body, and multiple floating balls symmetrically arranged around the body. The base and the body are connected in a rotating manner. When the body is in use, the base will contact the soil layer in the water. When the soil layer is soft and the base tilts, the multiple floating balls located around the body will always be subject to vertical upward buoyancy, so that the body will always remain stable and will not tilt with the base, thereby improving the stability of the projection work; When the base contacts the soil layer, multiple embedded plates will be inserted into the soil layer in the water, and the lower surface of the base will be against the soil layer, so as to fix the base. When the floating ball is vertically upward under the influence of the buoyancy in the water, multiple connecting ropes will also move up with multiple I-shaped blocks. At this time, under the action of the pressure, multiple auxiliary nails will pass through multiple openings and be inserted into the soil layer, so that the embedded plates are in a cross shape in the soil layer, which strengthens the grip of the base, plays an auxiliary fixing effect on the base, and improves the stability of the base supporting the body; After long-term use, the surface of the float will be damaged. When air leaks, if the damaged part is small, the water surface has tension and will not enter from the smaller damaged part. At this time, under the action of the guide rod, the gas in the float symmetrical to the float will flow from the guide rod into the damaged float, so that the internal air pressure of the two symmetrical floats is the same, and the buoyancy they receive is also the same, so as to avoid the buoyancy difference caused by the air leak of the float, which will cause the body to tilt in the water; When the surface of the float is severely damaged, that is, the damaged area is large, water will enter the two symmetrically arranged installation rods from the damaged area. The floating plate located in the installation rod will be affected by the buoyancy and will move up with the trapezoidal plate. In the process of moving up, the lock between the two installation rods and the machine body will be released, so that the two installation rods are separated from the machine body, thereby preventing the machine body from tilting in the water and quickly reminding the staff to quickly replace the float.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Reference Figure 1-Figure 9 A structure for supporting a virtual reality simulation device for experiencing an underwater world, comprising a body 1, a spherical groove is provided on the lower surface of the body 1, a ball 2 is roamingly embedded in the spherical groove, and the ball 2 is fixedly mounted on a cross-shaped base 3 through a connecting rod 29; The upper surface of the body 1 is provided with four mounting openings 18, and the lower surface of the body 1 is provided with four L-shaped mounting rods 4, which are locked to the lower surface of the body 1 by a locking assembly, and a mounting cavity 5 is provided in the mounting rod 4, and a bellows 6 is fixedly installed at the top of the mounting rod 4, and a floating ball 7 is fixedly installed at the top of the bellows 6, and a plurality of floating balls 7 are symmetrically arranged; When it is necessary to use the device for underwater projection to create a three-dimensional virtual world that reflects the changes and interactions of physical objects in real time for the audience, the device is first placed underwater and a suitable position is found, that is, a relatively flat soil layer, and then the base 3 is pressed against the soil layer in the water. At this time, the multiple floats 7 will be vertically upward under the action of buoyancy, and because the multiple floats 7 are symmetrically arranged, the body 1 located in the water will also be affected by the buoyancy of the multiple floats 7. Even if the base 3 in contact with the soil layer during the projection of the body 1 is tilted due to the soft soil layer, the ball 2 will rotate in the spherical groove. At this time, the body 1 will be in a stable state under the buoyancy of the multiple floats 7 and will not tilt with the base 3, so that the image projected by the body 1 remains stable, thereby improving the stability of the projection of the base 3.

[0018] A plurality of embedded plates 8 are vertically fixedly installed on the lower surface of the base 3, and a mounting groove 28 is vertically opened on the top of the embedded plate 8. The left and right side walls of the embedded plate 8 are opened with through holes, and auxiliary nails 9 are inserted in the through holes for sliding sealing. A placement plate 25 is fixedly installed on one end of the auxiliary nail 9 located in the mounting groove 28, and a telescopic spring 10 is sleeved on the auxiliary nail 9. The two ends of the telescopic spring 10 are respectively fixedly connected to the surface of the placement plate 25 and the groove wall of the mounting groove 28. The two auxiliary nails 9 are controlled by a pressing component to move away from each other. The pressing component includes two connecting ropes 11, two first inclined plates 12 respectively fixedly installed on the top ends of the two placement plates 25, and two I-shaped blocks 13 respectively fixedly installed at the bottom ends of the two connecting ropes 11. A sliding opening 14 is opened on the surface of the first inclined plate 12, and the two I-shaped blocks 13 are respectively slidably arranged in the two sliding openings 14. A plurality of through holes are opened on the upper surface of the base 3, and the plurality of connecting ropes 11 respectively pass through the plurality of through holes, and the top ends are respectively fixedly installed on the surfaces of the plurality of floating balls 7 in pairs; When the base 3 needs to be fixed, the device is first placed underwater, and the multiple floating balls 7 are manually controlled not to move up. Then, after finding a suitable position for placing the device, the multiple embedded plates 8 are controlled to be inserted into the soil layer at that position until the lower surface of the base 3 is in contact with the upper surface of the soil layer, which can play the role of fixing the base 3. At this time, the restriction on the multiple floating balls 7 is released, and the floating balls 7 will move up quickly due to the buoyancy of the water, and the multiple bellows 6 will also be quickly deformed into a vertical state, that is, the multiple floating balls 7 and the multiple bellows 6 will all be in a vertical state under the action of buoyancy. When the floating ball 7 is not in a vertical state, the connecting rope 11 connected to the floating ball 7 will be in a loose state, and the multiple I-shaped blocks 13 will be separated. The top of the connecting rope 11 will move upward with the floating ball 7, and the bottom of the connecting rope 11 will move upward with the I-shaped block 13, and the multiple connecting ropes 11 will be in a taut state at this time. Each I-shaped block 13 will slide in the multiple sliding openings 14 respectively, and will slide to the top of the sliding openings 14. Under the action of the inclined surface pressing, the two auxiliary nails 9 located in the installation groove 28 will move away from each other in the horizontal direction, and the ends of the multiple auxiliary nails 9 will pass through the multiple through openings respectively and insert into the soil layer. At this time, the embedded plate 8 will be in a cross shape in the soil layer, thereby strengthening the grip of the base 3, and can play the effect of auxiliary fixing the embedded plate 8, thereby improving the stability of the base 3 supporting the body 1; Then, when the embedded plate 8 needs to be pulled out from the soil layer, the multiple floats 7 are controlled to move downward first, and the pressing force of the multiple I-shaped blocks 13 on the multiple first inclined plates 12 disappears. The multiple auxiliary nails 9 will quickly move and reset under the elastic potential energy of the telescopic springs 10, thereby moving out of the soil layer and retracting into the installation grooves 28. At this time, the multiple auxiliary nails 9 no longer prevent the multiple embedded plates 8 from being moved out of the soil layer, and then the base 3 is pulled vertically upward until the multiple embedded plates 8 are pulled out of the soil layer. It is convenient and quick.

[0019] The locking assembly includes a rectangular plate 15 fixedly mounted on the upper surface of the mounting rod 4, a spring rod 16 fixedly mounted on the surface of the rectangular plate 15, and a triangular locking block 17 fixedly mounted on one end of the spring rod 16. The lower surface of the body 1 is provided with a plurality of rectangular grooves 19 for inserting the plurality of rectangular plates 15, and the wall of the rectangular groove 19 is provided with a locking opening 20 connected to the mounting opening 18. When installing the mounting rod 4, firstly, the mounting rod 4 is placed under the machine body 1, and the mounting rod 4 or the machine body 1 is rotated so that the plurality of rectangular plates 15 are aligned with the plurality of rectangular grooves 19 respectively, and then the machine body 1 is controlled to move downward or the mounting rod 4 is controlled to move upward so that the plurality of locking blocks 17 enter the plurality of rectangular grooves 19 respectively. During the entering process, the plurality of rectangular plates 15 will also enter the plurality of rectangular grooves 19 respectively, and the inclined surfaces of the plurality of locking blocks 17 will respectively slide in contact with the groove walls of the plurality of rectangular grooves 19. Under the action of the inclined surfaces pressing, the plurality of spring rods 16 will shrink until the plurality of rectangular plates 15 are locked. When the rectangular plates 15 move to the top ends and respectively abut against the top walls of the multiple rectangular grooves 19, the multiple locking blocks 17 will move to the positions corresponding to the multiple locking openings 20, and the pressing force exerted by the groove walls of the rectangular grooves 19 on the locking blocks 17 will disappear. The multiple locking blocks 17 will quickly move and reset under the elastic potential energy of the multiple spring rods 16, and be inserted into the locking openings 20 corresponding to their own positions. The lower surface of the locking block 17 located in the locking opening 20 will abut against the lower wall of the locking opening 20, thereby forming a snap connection, thereby completing the locking of the mounting rod 4, which is convenient and quick.

[0020] Every two opposite mounting rods 4 are connected by a guide rod 21, and the two guide rods 21 are staggered. The body 1 is located underwater for a long time. After long-term use, the surface of the float 7 may be damaged, causing the gas in the float 7 to leak from the damaged part. When the damaged part is small, due to the tension on the water surface, water will not enter the float 7 and the mounting rod 4 from the leaking part. When the float 7 is deflated, under the action of the guide rod 21, the gas in the float 7 symmetrical to the deflated float 7 will pass from the guide rod 21 into the damaged float 7, so that the air pressure inside the two symmetrical floats 7 is the same, and the buoyancy of the two symmetrical floats 7 is also the same. In this way, it can be avoided that a pressure difference is generated due to the deflation of one of the floats 7, resulting in the buoyancy of the float 7 symmetrical to the float 7 being greater than the buoyancy of the deflated float 7, thereby causing the body 1 to tilt in the water.

[0021] A separation assembly is provided in the installation cavity 5, and the separation assembly is used to release the lock between the installation rod 4 and the body 1, so that the float 7 and the installation rod 4 are separated from the body 1. The separation assembly includes a floating plate 22 and a trapezoidal plate 23 fixedly installed on the upper surface of the floating plate 22. A fixed plate 26 is fixedly sleeved on the spring rod 16, and a second inclined plate 24 is fixedly installed at the bottom end of the fixed plate 26. A socket is opened on the upper surface of the installation rod 4, and the trapezoidal plate 23 is slidably and sealedly inserted in the socket, and the inclined surface is arranged face to face with the inclined surface of the second inclined plate 24. A sliding rod 27 is vertically fixedly installed in the installation cavity 5, and the floating plate 22 is slidably sleeved on the sliding rod 27; In the initial state, that is, when the float 7 is not damaged, the float plate 22 in the installation cavity 5 will not move up. Only when the surface of the float 7 is severely damaged, that is, the damaged part is large, water will enter the damaged float 7 and the installation rod 4 connected to the float 7 from the damaged part, and then enter the installation rod 4 symmetrically arranged with the installation rod 4 from the guide rod 21. The float plate 22 in the installation cavity 5 will be affected by the buoyancy and move up with the trapezoidal plate 23. In the process of moving up, the inclined surface of the trapezoidal plate 23 will slide in contact with the inclined surface of the second inclined plate 24. Under the action of the inclined surface pressure, the two spring rods 16 will shrink, so that the two locking blocks 17 respectively located at the ends of the two spring rods 16 will also move with the two spring rods 16. The two symmetrically arranged mounting rods 4 are separated from the body 1, so that the damaged buoy 7 and the symmetrically arranged buoy 7 will also fall off together, thereby preventing the body 1 from tilting in the water and also quickly reminding the staff to quickly replace the buoy 7. Because if the buoy 7 is not seriously damaged and the part is small, it can still be used. When the damage is serious and the part is large, the buoy 7 must be replaced to avoid a greater impact on the projection of the body 1 due to the serious damage of the buoy 7.

[0022] In the present invention, when it is necessary to use the device for underwater projection to create a three-dimensional virtual world that reflects the changes and interactions of physical objects in real time for the audience, the device is first placed underwater and a suitable position is found, that is, a relatively flat soil layer, and the base 3 is placed against the soil layer in the water. At this time, multiple floats 7 will be vertically upward under the action of buoyancy, and because the multiple floats 7 are symmetrically arranged, the body 1 located in the water will also be affected by the buoyancy of the multiple floats 7. Even if the base 3 in contact with the soil layer is tilted due to the soft soil layer, the ball 2 will rotate in the spherical groove. At this time, the body 1 will be in a stable state under the buoyancy of the multiple floats 7 and will not tilt with the base 3, so that the image projected by the body 1 remains stable, thereby improving the stability of the projection of the base 3.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
