[0024] By setting up the sand box body 1, the sand box body 1, the top plate 4 and the base 6 are all integrally formed, and the integral forming makes the sand box body 1, the top plate 4 and the base 6 stronger. At the same time, the stability of the sand box body 1 is further improved by cooperating with the reinforcing sheet 2 and the series support column 3. During the sand filling process of the sand box body 1 and the subsequent disassembly process, only one of the sand box bodies 1 needs to be filled with sand or injected with water, which improves the efficiency during the disassembly process and the fixing process.

[0025] Both ends of the base 6 are movably connected with a plug sleeve 7, and the top of the plug sleeve 7 is fixedly connected with a toggle block, one end of the plug sleeve 7 is plugged into the inside of the plug interface 9, and the plug interface 9 is opened inside the top of the connecting seat 10, and the connecting seat 10 is fixedly connected to the top of the fixed base 11 used to connect and fix to the ground, and the fixed base 11 and the connecting seat 10 are an integrally formed structure.

[0026] By setting the plug-in sleeve 7, the plug-in sleeve 7 is plugged into the inside of the plug-in port 9 during use. Since a large amount of yellow sand will be filled inside the sand box body 1 during use, vertical pressure is used to ensure the stability between the sand box body 1 and other components and the connecting seat 10 and the fixed base 11. The connecting seat 10 and the fixed base 11 are designed to be separated from the sand box body 1 and other components. In this way, the connecting seat 10 and the fixed base 11 can be installed first and then connected and fixed to the sand box body 1, which is convenient for operation. Compared with the traditional integrated design, this is easier to install and disassemble.

[0027] The top of the top plate 4 is symmetrically fixedly connected with a limit frame 12 with a "concave" structure, and a mounting frame 13 is inserted into the interior of the limit frame 12. The outer walls on both sides of the limit frame 12 are symmetrically provided with latch openings connected to the inner side walls of the limit frame 12, and fixed latches 15 are inserted into the interior of the latch openings. One end of the fixed latch 15 is movably connected to the inside of one end of the mounting sleeve 14, and the mounting sleeve 14 is symmetrically fixedly connected to the inner walls on both sides and is located inside the mounting frame 13. A return spring 16 is fixedly connected to one end of the inner end of the mounting sleeve 14, and one end of the return spring 16 is fixedly connected to one end of the fixed latch 15. The end of the mounting sleeve 14 away from the fixed latch 15 is movably connected with a connecting column 17, and one end of the connecting column 17 is fixedly connected to a limit pull ring 18 located outside the mounting sleeve 14, and one end of the connecting column 17 passes through one end of the return spring 16 and is fixedly connected to one end of the return spring 16 close to the fixed latch 15.

[0028] By setting the limit frame 12, the limit frame 12 can be flexibly disassembled and assembled with the installation frame 13, making it more flexible during the assembly process and the disassembly process. The limiting method between the limit frame 12 and the installation frame 13 is that the potential energy generated by the reset spring 16 drives the fixed pin 15 to move, so that it is plugged into the inside of the pin port, thereby completing the limiting. During the disassembly process, the reset spring 16 is retracted by the limit pull ring 18 cooperating with the connecting column 17, thereby separating the fixed pin 15 from the pin port, and finally releasing the fixation between the limit frame 12 and the installation frame 13.

[0029] The inner side wall of the mounting frame 13 is symmetrically fixedly connected with a guide rail 19 having a "convex" structure, and the inside of the guide rail 19 is movably connected with a guide slider 20 having a "convex" structure, the top of the guide slider 20 is fixedly connected to the bottom end of the mounting seat 21, and the top of the mounting seat 21 is fixedly connected to the dock block 22, the corresponding inclined surfaces of the dock block 22 are tightly connected with a wooden pad 26, and the wooden pad 26 is plugged with a plug-in blade 25 at one end close to the dock block 22, one end of the plug-in blade 25 is fixedly connected with a movable block 24, and the movable block 24 is movably connected to the inside of the movable cavity 23, the movable cavity 23 is symmetrically opened inside the dock block 22, and a connecting frame 27 is fixedly connected between the ends of the movable cavity 23 close to the vertical surface of the dock block 22.

[0030] By setting the dock blocks 22, an interval for limiting the position of the ship is formed between the two dock blocks 22, and the dock blocks 22 are fixed by wooden pads 26 on the inclined surface, which can effectively avoid the deformation of the dock blocks 22. The spacing between the dock blocks 22 can be quickly adjusted according to actual needs.

[0031] The bottom end of the mounting seat 21 is fixedly connected with a transmission screw sleeve 28, and the inner side wall of the transmission screw sleeve 28 is penetrated and meshed with a connecting screw 29, one end of the connecting screw 29 is movably connected to one end of the mounting frame 13, and a driving knob 30 is arranged in the middle between the connecting screws 29, and the two ends of the driving knob 30 are respectively fixedly connected to one end of the connecting screw 29, and the thread teeth of the connecting screws 29 on both sides are arranged in opposite structures.

[0032] By setting the driving knob 30, the driving knob 30 is rotated forward or reversely during use, so that the driving knob 30 synchronously drives the connecting screws 29 at both ends to rotate, and then the connecting screws 29 are respectively meshed with the transmission screw sleeves 28 to form a screw transmission structure, driving the guide slider 20, the mounting seat 21 and the dock block 22 to move.

[0033] The specific use process of this embodiment is as follows: First, the sand box body 1 is adapted according to the size and weight ratio of the hull, and then the connecting seat 10 and the fixed base 11 are installed first, and then connected and fixed with the sand box body 1, and plugged into the inside of the plug interface 9 through the plug sleeve 7. In addition, since a large amount of yellow sand will be filled inside the sand box body 1 during use, vertical pressure is applied to ensure the stability between the sand box body 1 and other components and the connecting seat 10 and the fixed base 11; Secondly, by setting the sand box body 1, the sand box body 1, the top plate 4 and the base 6 are all integrally formed, and the integral forming makes the sand box body 1, the top plate 4 and the base 6 stronger. At the same time, the stability of the sand box body 1 is further improved by the reinforcement sheet 2 and the series support column 3. And it is only necessary to fill the sand into one of the sand box bodies 1. Since the sand box bodies 1 are connected with the transmission pipe 31, after the sand is filled into the sand box body 1 to a certain amount, the sand will be transmitted to the other sand box bodies 1 through the transmission pipe 31. This can avoid the trouble of filling sand one by one. After the sand filling is completed, the transmission pipe 31 is also filled with sand. This creates a chain force between the connected sand box bodies 1, further improving the stability. At the same time, during the disassembly process, it is only necessary to fill water into one of the sand box bodies 1. In this way, the sand filled in the sand box body 1 can be discharged very quickly through the dilution of water and sand. Afterwards, the limiting frame 12 is set so that the limiting frame 12 can be flexibly disassembled and assembled with the installation frame 13, making it more flexible during the assembly process and the disassembly process. The limiting method between the limiting frame 12 and the installation frame 13 is that the potential energy generated by the reset spring 16 drives the fixed latch 15 to move, so that it is plugged into the inside of the latch port, thereby completing the limiting. During the disassembly process, the reset spring 16 is retracted by the limiting pull ring 18 and the connecting column 17, so that the fixed latch 15 is separated from the latch port, and finally the fixing between the limiting frame 12 and the installation frame 13 is released; Then, an interval for limiting the position of the ship is formed between two dock blocks 22, and the dock blocks 22 are fixed by wooden pads 26 on an inclined surface, which can effectively avoid deformation of the dock blocks 22, and the spacing between the dock blocks 22 can be quickly adjusted according to actual needs; By rotating the driving knob 30 forward or reversely during use, the driving knob 30 synchronously drives the connecting screws 29 at both ends to rotate, and then the connecting screws 29 are respectively meshed with the transmission screw sleeves 28 to form a screw transmission structure, driving the guide slider 20, the mounting seat 21 and the dock block 22 to move, and thus a sand box structure for diving equipment is completed.

[0034] Example 2: Please refer to Figure 8 The present invention provides a sand box structure for diving equipment. The structure of the sand box body 1 and the preparation steps for supporting the diving equipment are as follows: S1: First, the size and volume of the sand box body 1 are designed according to the diving equipment to be supported; S2: The sand box body 1 is formed in one piece; S3: connecting the transmission pipe 31 of the inclined structure between the flask bodies 1, and sealing the communication port 8 not connected to the transmission pipe 31; S4: Select a carrier for filling the flask body 1; S5: The selected carrier for filling the flask body 1 is transferred to one of the flask bodies 1 by means of a transfer pump; S6: The inside of the sand box body 1 is continuously filled with the carrier. When the carrier in the sand box body 1 rises to the connecting port 8, it is transmitted to the connected sand box body 1 through the connecting pipe; S7: Filling a plurality of flask bodies 1 with carriers larger than a required filling carrier threshold is completed.

[0035] In S4, the carrier is sand, and the sand used for the carrier is selected to have good fluidity, and the friction between the sand and the sand box body 1 causes the sand to flow and the flow rate. According to Newton's second law , For the combined external force, is the mass of the object, is the acceleration, and during the flow of sand, it is affected by gravity and the friction of the inner wall of the sand box body 1, and the fluidity of the selected sand is verified. When the fluidity of the set sand meets the calculated fluidity threshold, the sand can be transmitted in the sand box body 1.

[0036] In S6, the principle of sand transmission between the plurality of sand box bodies 1 is that after the carrier is continuously filled inside the sand box body 1, the pressure inside the sand box body 1 changes, so that the pressure inside the sand box body 1 increases. The specific expression is as follows:

[0037] in the formula Expressed as pressure, is the density of sand, Expressed as the acceleration due to gravity, It is expressed as the height of the sand; The pressure therefore depends on the final height of the sand in each box.

[0038] In S7, after the interior of the flask body 1 is filled with the corresponding carrier, the interior of the transmission pipe 31 is also filled with the carrier, so that a linkage force is generated therebetween.

[0039] Example 3: Please refer to Fig. 9 and Fig.10The present invention provides a sand box structure for diving equipment, including a transmission pipe 31. The transmission pipe 31 is arranged in an inclined structure, and both ends of the transmission pipe 31 are connected with connectors adapted to the inner wall of the connecting port 8 through a rotating joint. A transmission component 32 for enhancing the flowability of sand can also be arranged in the middle of the transmission pipe 31.

[0040] By setting up the transmission pipe 31, the sand box body 1 can be transmitted to the connected sand box body 1 through the transmission pipe 31. When encountering poor transmission effect, the transmission pipe 31 with a transmission component 32 in the middle can be selected, and the transmission component 32 can be used to enhance the fluidity of sand. The transmission component 32 is a transmission pump structure setting.
