Description

Technical Field

[0001] This utility model relates to the field of cultural relic cleaning technology, specifically to a multifunctional flotation device for underwater cultural relics. Background Technology

[0002] With the development of underwater archaeology, the research and protection of marine artifacts recovered from the sea have received increasing attention and importance, becoming an important branch of cultural relic protection. These artifacts, having been immersed in seawater for extended periods and subjected to the long-term effects of marine organisms and calcareous materials such as sea mud, accumulate a large amount of salt. After being salvaged, due to changes in environmental factors, this salt repeatedly dissolves, crystallizes, and recrystallizes, leading to corrosion and damage to the artifacts. For example, ceramics may experience glaze detachment, becoming brittle and fragile, and metals may suffer accelerated corrosion. Furthermore, the salvaged artifacts often bear a significant amount of dirt. To better protect these artifacts, cleaning and desalination are crucial tasks that require significant water consumption. Therefore, a multifunctional flotation device for underwater artifacts is urgently needed, capable of flotation cleaning and desalination while conserving water resources. Utility Model Content

[0003] The purpose of this invention is to provide a multifunctional flotation device for underwater cultural relics, which can perform flotation cleaning and desalination of underwater cultural relics while saving water resources.

[0004] To achieve the above objectives, a multifunctional underwater artifact flotation device is provided, comprising a flotation cleaning tank body, a support frame, and a controller. A micron-sized bubble generator is located at one bottom end of the flotation cleaning tank body. A coarse screen grid is mounted on the micron-sized bubble generator and installed on the flotation cleaning tank body. An overflow trough is located on one side of the coarse screen grid. A fine screen support trough is located on one side of the flotation cleaning tank body, used to hold the fine screen grid, which is located below the overflow trough. A fine screen is located on the side of the coarse screen grid away from the overflow trough. A vertically arranged isolation grid plate is located in the middle of the flotation cleaning tank body, with stirring blades on the isolation grid plate. The micron-sized bubble generator is connected to an air pump. A fine screen overflow pipe is located below the fine screen grid. A faucet is located on the flotation cleaning tank body, connected to the outlet of a water pump. The fine screen overflow pipe is connected to the inlet of a water pump. The water pump, stirring blades, and air pump are all electrically connected to the controller.

[0005] Furthermore, the main body of the flotation washing tank is provided with a water inlet connector on the outer wall of the end away from the coarse screen grid. The outlet of the water inlet connector is connected to a faucet. The water inlet connector has two inlets, one connected to the outlet of the water pump and the other connected to the water inlet valve. The water inlet valve is connected to an external water inlet pipe.

[0006] Furthermore, a drain pipe is provided below the main body of the flotation washing tank, and a drain valve is provided on the drain pipe. The overflow pipe of the fine screen is connected to the drain pipe, the drain pipe is connected to the water pump, and a drain valve is also provided on the drain pipe.

[0007] Furthermore, the bottom surface of the bracket is provided with height-adjustable support feet.

[0008] Furthermore, the support foot is an adjusting bolt.

[0009] Furthermore, a salinity sensor is installed inside the main body of the flotation washing tank, and the salinity sensor is electrically connected to the controller.

[0010] Furthermore, it also includes an audible and visual alarm module, which is electrically connected to the controller.

[0011] Furthermore, the drain outlet at the bottom of the main body of the flotation washing tank is equipped with a plug.

[0012] Principles and advantages:

[0013] 1. Flotation cleaning function: Select an appropriate amount of material to be filtered and put it into the coarse screen mesh. At this time, the bubbles generated by the micron bubble generator will disturb the water flow upward, assisting the staff in filtering the material. Materials with a diameter smaller than the coarse screen mesh and a density higher than water (such as silt) will pass through the screen and sink to the bottom of the water, while materials with a density less than water (such as plant seeds) will float on the surface of the water. The water will flow into the fine screen mesh through the overflow tank.

[0014] 2. Flow Function: Water passing through the fine screen can be recycled by a water pump, saving water. It then re-enters the main body of the flotation washing tank through a tap. The isolation grid plate and stirring blades enable unidirectional water flow. Combined with the upward turbulent water flow generated by the micron bubble generator, fine particles of contaminant water are discharged through the overflow trough back into the fine screen for filtration, preventing a rapid increase in turbidity in the main body of the flotation washing tank and thus avoiding a complete water replacement, thereby achieving better water conservation.

[0015] 3. Cleaning function: The faucet with rotating, telescopic and pull-out functions can clean cultural relics from multiple angles.

[0016] 4. Desalination Function: After the initial cleaning is completed, open the plug, drain valve, and reverse-drive agitator to drain the water from the main body of the flotation cleaning tank through the drain pipe. Then close the drain valve and drain valve, and refill the main body of the flotation cleaning tank with clean water through the external inlet pipe, inlet connector, and faucet. Place the initially cleaned artifacts into the coarse screen for soaking and desalination. The salinity sensor is used to detect the salinity of the water. When the salinity exceeds the threshold, the audible and visual alarm module will sound an alarm to remind the staff to change the water. Attached Figure Description

A fine screen is provided on the side of the coarse screen 9 away from the overflow trough. A vertically arranged isolation grid plate 15 is provided in the middle of the flotation washing tank body 5, and an agitator blade 16 is provided on the isolation grid plate 15. The agitator blade 16 can dredge the disturbed water flow through the fine screen and then flow to the guide flange, thereby realizing water flow and reducing the turbidity of the water.

[0025] The micron bubble generator 8 is connected to the air pump 12, which is located in the frame below the fine screen support groove 11. The air pump switch 7 is located on the outer surface of the frame. A fine screen overflow pipe 13 is provided below the fine screen mesh 10.

The faucet 1 is connected to the outlet of the water pump, and the fine screen overflow pipe 13 is connected to the inlet of the water pump.

[0026] The flotation washing tank body 5 is provided with a water inlet connector 2 on the outer wall of the end away from the coarse screen grid 9. The outlet of the water inlet connector 2 is connected to a water tap 1. The water inlet connector 2 has two inlets, one connected to the outlet of the water pump and the other connected to the water inlet valve 4. The water inlet valve 4 is connected to an external water inlet pipe.

[0027] A drain pipe is located below the main body 5 of the flotation washing tank, and a drain valve 14 is installed on the drain pipe. The fine screen overflow pipe 13 is connected to the drain pipe, which is connected to a water pump. A drain valve is also installed on the drain pipe. A plug is installed at the bottom of the main body 5 of the flotation washing tank to prevent blockage caused by long-term sediment deposition. The plug can be removed when drainage is needed.

[0028] The bottom surface of the bracket is provided with height-adjustable support feet 3. The support feet 3 are adjustment bolts.

[0029] A salinity sensor is installed inside the main body 5 of the flotation washing tank; in this embodiment, a conventional salinity sensor is used.

The specific functions of this solution are as follows:

[0030] 1. Flotation cleaning function: Select an appropriate amount of material to be filtered and put it into the coarse screen grid 9. At this time, the bubbles generated by the micron bubble generator 8 disturb the water flow upward, assisting the staff in filtering the material. Substances with a diameter smaller than the coarse screen mesh and a density higher than water (such as silt) pass through the screen and sink to the bottom of the water, while substances with a density less than water (such as plant seeds) float on the surface of the water. The water flows into the fine screen grid 10 with the overflow tank.

[0031] 2. Flow Function: Water passing through the fine screen 10 can be recycled by a water pump, saving water. Then, it re-enters the main body of the flotation washing tank 5 through the tap 1. The isolation grid plate 15 and the stirring fan blades 16 enable unidirectional water flow. Combined with the upward turbulent water flow generated by the micron bubble generator 8, the fine particulate waste water can be discharged into the fine screen 10 through the overflow trough for filtration, preventing the turbidity of the water in the main body of the flotation washing tank 5 from rising rapidly and requiring a complete water change, thus achieving a better water-saving effect.

[0032] 3. Cleaning function: The faucet 1, which has functions such as rotation, extension and pull-out, can clean cultural relics from multiple angles.

[0033] 4. Desalination Function: After the initial cleaning is completed, open the plug, drain valve 14, drain valve, and reverse-drive stirring fan blade 16 to drain the water from the main body of the flotation cleaning tank 5 through the drain pipe. Then close the drain valve 14 and drain valve, and refill the main body of the flotation cleaning tank 5 with clean water through the external water inlet pipe, water inlet connector 2, and faucet 1. Then place the initially cleaned artifacts into the coarse screen 9 for soaking and desalination. The salinity sensor is used to detect the salinity of the water. When the salinity exceeds the threshold, the audible and visual alarm module will sound an alarm to remind the staff to change the water.
