Description

Technical Field

[0001] This invention relates to the field of valve box technology, specifically to a small ship self-draining sand valve box device. Background Technology

[0002] Due to their shallow draft, small vessels typically draw in seawater directly from the outside or bottom when taking in water, such as ballast water, cooling water, or fire-fighting water for workboats. Seawater often contains a lot of floating debris, especially near ports where there is a large amount of silt. This siltation can negatively impact equipment operation and even cause damage. Current self-draining valve boxes for small vessels are not ideal for sedimentation and purification, require frequent filter replacements, and are difficult to inspect for corrosion. Especially under seawater immersion, leakage is a potential hazard. Automatic detection and isolation of corrosion points are also difficult. Furthermore, traditional water storage methods can affect the vessel's safe handling and maneuverability when turning or when the water level is too high. The valve boxes are also not ideal for automatic drainage to prevent tilting.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention employs a corrosion isolation section that can be used for real-time detection of corrosion on the inner wall of a water storage tank. It enables non-destructive testing. Furthermore, this structure utilizes the conductivity of the corroded water tank to perform comprehensive testing. In conjunction with lifting accessories, this structure automatically alerts the system upon detecting corrosion and isolates the corroded location, preventing traditional corrosion detection structures from failing to address the issue in time, which could lead to further corrosion, reduced service life, or even leakage.

[0017] By employing attitude counterweight test components, the attitude of a vessel can be monitored in real time. This is especially useful for small vessels equipped with large valve box inlet structures, where the water volume in the valve box directly affects the vessel's center of gravity adjustment and stability. This structure can detect the vessel's attitude in real time when it tilts too much and perform drainage work, which can assist the vessel in preventing capsizing, increase the vessel's maneuverability, reduce safety hazards, and prevent capsizing due to inertial torque imbalance.

[0018] The use of a closed control unit, in conjunction with a water storage tank, allows for water storage and sedimentation before water intake, which improves the purity of the water intake and reduces the high frequency of filter replacement caused by traditional filter-based water intake methods. This extends the maintenance cycle, increases filter life, and facilitates automatic removal of sediment without the need for tedious manual cleaning. The upper-layer water intake unit can absorb seawater from the upper layer in real time, reducing the amount of seawater with a high sediment content in the lower layer that needs to be drawn in.

[0034] The water storage component 1 includes: a filter screen block 104, an air inlet pipe 105, and an indicator light 106. The filter screen block 104 is fixedly installed inside the water storage tank 101; the filter screen block 104 has a mesh structure; the air inlet pipe 105 is fixedly installed on the water storage tank 101; an electric air pump is connected to the air inlet pipe 105; an indicator light 106 is fixedly installed on the water storage tank 101. The sealing control component 2 includes: a sliding mounting block 201, a lifting shaft 202, an electromagnet 203, a tension spring 204, and a lower baffle 205. The sliding mounting block 201 is fixedly installed on the water storage tank 101; the sliding mounting block 201 has a hexagonal hole; the lifting shaft 202 is slidably mounted on the sliding mounting block 201, and the upper section of the lifting shaft 202 has a hexagonal column structure; an electromagnet 203 is fixedly sleeved on the top of the lifting shaft 202; a tension spring 204 is sleeved on the lifting shaft 202, and the tension spring 204 is connected to... Between the lifting shaft 202 and the sliding mounting block 201; the sliding mounting block 201 has a ring of through holes; a lower baffle 205 is fixedly installed at the bottom of the lifting shaft 202; the lower baffle 205 has a row of through grooves; protrusions are provided between the row of through grooves on the lower baffle 205; a row of protrusions on the lower baffle 205 seals and fits against the liquid inlet grate 103; the lifting shaft 202 slides through the middle of the liquid inlet grate 103; the pressure control component 3 includes: a pressure mounting plate... The system includes a cover 301, a threaded rod 302, and a suction pipe 303. The cover 301 is bolted to the water storage tank 101. The threaded rod 302 is threaded onto the cover 301. A handwheel is provided at the top of the threaded rod 302. The bottom of the threaded rod 302 is fitted inside the cover 301. The suction pipe 303 is fixedly installed on the cover 301. A water pump is connected to the external suction pipe 303.The downward-pressing threaded rod 302 aligns with the lifting shaft 202. The enclosed control component 2, in conjunction with the water storage tank 101, allows for water storage and sedimentation before water intake, improving water purity and reducing the high filter replacement frequency associated with traditional filter-based water intake methods. This extends maintenance cycles and improves filter lifespan, while also facilitating automatic sediment removal without requiring tedious manual cleaning, ensuring long-term usability. Furthermore, the structure utilizes a liftable, adjustable lower baffle 205 that fits snugly against the inlet grate 103, providing a smooth surface that does not affect ship navigation resistance and allows for real-time sediment removal. The downward-pressing control component 3 allows for manual control of the lifting shaft 202's opening and closing, avoiding circuit issues. The problem causes uncontrollable water intake. When water intake is needed, the electromagnet 203 can be activated to electromagnetically attract the sliding mounting block 201. The lower baffle 205 will no longer be closed to the inlet grate 103, allowing water to enter and fill the water storage tank 101. Once the tank is full, the electromagnet 203 can be de-energized, and the tension spring 204 will pull, closing the lower baffle 205 and allowing seawater sediment and impurities to settle naturally. Water can then be drawn out through the suction pipe 303. When the lower baffle 205 is lowered again for water intake, the sediment and impurities settled on it can be discharged naturally, preventing sediment accumulation.

[0035] The upper water-absorbing component 4 includes: an upper water-absorbing pipe 401, a sliding mesh sleeve 402, and a buoyancy ring 403. The upper water-absorbing pipe 401 is fixedly installed inside the water storage tank 101. A lifting shaft 202 is slidably sleeved on the upper water-absorbing pipe 401. The sliding mesh sleeve 402 is slidably sleeved on the upper water-absorbing pipe 401, and the sliding mesh sleeve 402 has mesh holes. The buoyancy ring 403 is fixedly sleeved on the sliding mesh sleeve 402. The buoyancy ring 403 is located in the middle of the sliding mesh sleeve 402. The buoyancy ring 403 is used to float on the upper surface of the liquid. The upper water-absorbing component 4 also includes: a rubber sleeve 404 and a connecting hose 405. The end of the rubber sleeve 404 is fixedly sleeved on the upper water-absorbing pipe 401. The other end is fixedly installed in the middle of the liquid inlet grate 103; a connecting hose 405 is fixedly installed on the rubber sleeve 404; the other end of the connecting hose 405 is connected to the bottom of the sliding mesh sleeve 402; the connecting hose 405 is connected to the suction pipe 303; the upper water suction component 4 can be used to absorb the seawater in the upper layer in real time, which can reduce the amount of seawater with a large amount of silt in the lower layer, ensure the service life of the sliding mesh sleeve 402, and improve the water intake quality of this structure. At the same time, this structure can automatically adjust with the rise and fall of the liquid level, which can avoid safety hazards. After the water tank 101 is filled with water, the buoyancy ring 403 can rise and fall with the liquid level. During the process, the sliding mesh sleeve 402 can absorb water in real time on the upper layer of the liquid surface.

[0036] The lifting adapter 5 includes: a lifting plate 501, an internal electrode 502, and a humidifying sponge ring 503. The lifting plate 501 is slidably fitted inside the water tank 101. The internal electrode 502 is fixedly installed on the lifting plate 501. The humidifying sponge ring 503 is fitted on the lifting plate 501 and is attached to the inside of the water tank 101. The corrosion isolation part 6 includes: a pressure tank 601, a conduit 602, and an expansion rubber pad 603. The pressure tank 601 is fixedly installed on the lifting plate 501. The pressure tank 602 is fixedly installed on the pressure tank 601. A conduit 602 passes through a lifting plate 501; a solenoid valve is installed on the conduit 602; an expansion rubber pad 603 is fixedly installed on the lifting plate 501; the expansion rubber pad 603 is connected to a pressure tank 601; the expansion rubber pad 603 is used to expand and fit between the lifting plate 501 and the water tank 101; an internal power supply 502, an external power terminal 102, a solenoid valve on the conduit 602, and an indicator light 106 are connected in series; a corrosion isolation section 6 is used to detect the corrosion of the inner wall of the water tank 101 in real time, which can realize non-destructive testing. This structure utilizes the corrosion of the water tank 101. The post-conductive characteristic allows for comprehensive inspection. This structure, in conjunction with the lifting adapter 5, automatically alerts upon detecting corrosion and isolates the corroded area. This avoids the problem of traditional corrosion detection structures failing to address corrosion promptly, leading to further corrosion, reduced service life, and even leaks. This structure provides direct detection and rapid isolation. Corrosion damages the sealing and strength of ballast water tanks and related piping systems, causing ballast water system failure. This not only affects the ship's center of gravity and stability but may also accelerate the spread of corrosion to other parts of the hull, creating a vicious cycle. Corrosion can also lead to galvanic corrosion and crevice corrosion. For example, potential difference corrosion at the contact points of different metals can accelerate the damage of critical components such as valves and filters. If the paint on the inner wall of the water tank 101 peels off, the humidifying sponge ring 503 will first come into contact with the rusted area. At this time, the indicator light 106 will be powered on to light up as a warning. At the same time, the solenoid valve on the conduit 602 will also be energized and opened, so that the compressed air in the pressure tank 601 can be introduced into the expansion rubber gasket 603 through the conduit 602 for sealing and isolation. This will prevent the rusted area from being continuously corroded by seawater during continuous use. The seawater remaining on the humidifying sponge ring 503 will not cause continuous corrosion to the rusted area and will gradually evaporate.

[0037] In Example 2, based on Example 1, the attitude counterweight test piece 7 includes: a counterweight crossbar 701, a stop bar 702, and a swing arm 703. The counterweight crossbar 701 is fixedly installed on two water tanks 101; two stop bars 702 are fixedly installed at the bottom of the counterweight crossbar 701; the swing arm 703 is rotatably installed in the middle of the counterweight crossbar 701; a counterweight ball is provided at the bottom of the swing arm 703; the attitude counterweight test piece 7 also includes: a swing switch 704, with swing switches 704 fixedly installed on both sides of the swing arm 703, and the two swing switches 704 are electrically connected to electric air pumps connected to two air inlet pipes 105 respectively; the two stop bars 702 are respectively aligned with the two swing switches 704. Using the attitude counterweight test piece 7, the attitude of the ship can be detected in real time, especially for small ships. When equipped with a large valve box water inlet structure, the water volume in the valve box directly affects the ship's center of gravity adjustment and stability. This structure can detect the ship's attitude tilting in real time. When the water level is too high, drainage work can help prevent the ship from capsizing, increase the ship's maneuverability, and reduce safety hazards. The hull is prone to capsizing due to inertial torque imbalance when turning, especially in large waves or when making sharp turns, which greatly increases the risk. A large sea valve box during turning will increase water resistance, forcing the steering gear hydraulic system to operate under high load for a long time. If key components such as hydraulic pump drive belt or crankshaft are aging, it may cause steering gear failure, making it difficult to regain control in an emergency. This structure can detect and control the lifting plate 501 to move down to drain water in real time. When the ship rolls, if the roll angle is too large, the swing arm 703 will drive the swing switch 704 on the roll side to squeeze the stop bar 702 on the same side. At this time, the electric air pump connected to the air intake pipe 105 can quickly inflate the air, and the lifting plate 501 will move down to squeeze the seawater out of the water tank 101 on the same side. By reducing the counterweight on the roll side, it helps the ship to return to normal stability.

[0038] The working principle of this embodiment is as follows: First, two holes are made in the outer plate at the bottom of the hull. The two water storage tanks 101 are welded to the pre-drilled holes in the outer plate at the bottom of the hull for installation. When water intake is required, the electromagnet 203 is activated to electromagnetically attract the sliding mounting block 201. At this time, the lifting shaft 202 moves downward, the tension spring 204 is stretched, and the lower baffle 205 no longer seals against the inlet grate 103. Water can then enter the inlet grate 103 without obstruction, filling the water storage tank 101. Once the water storage tank 101 is full, the electromagnet 203 is de-energized, and the tension spring 204 is pulled, causing the lower baffle 205 to close the inlet grate 103. At this time, seawater sediment and impurities will naturally settle. Alternatively, the water can be manually rotated... Turning down the threaded rod 302 compresses the lifting shaft 202, controlling the water inlet operation. As the water tank 101 fills with water, the buoyancy ring 403 rises and falls with the liquid level. During this process, the sliding mesh sleeve 402 can draw water from the upper layer of the liquid surface in real time. When water is drawn in through the external water pump connected to the suction pipe 303, the upper suction pipe 401 can draw water between the upper suction pipe 401 and the lifting shaft 202. After being filtered by the filter block 104, the water is discharged. When water enters the water tank 101, the lifting plate 501 rises with the water level. During this process, the humidifying sponge ring 503 is soaked. If the paint on the inner wall of the water tank 101 peels off, the humidifying sponge ring 503 will first contact the rusted area and then... The column 502, the rusted area, and the external electrical terminal 102 form a conductive circuit. When the circuit is complete, the indicator light 106 is powered on and illuminates as a warning. Simultaneously, the solenoid valve on the conduit 602 is energized and opened, allowing compressed air from the pressure tank 601 to be introduced through the conduit 602 into the expansion rubber pad 603. The expansion rubber pad 603 rapidly expands, sealing the lifting plate 501 and the water tank 101. The anti-slip friction of the expansion rubber pad 603 provides positioning, preventing further corrosion from seawater immersion during continuous use. When the ship tilts due to turning or other factors, the swing arm 703 remains vertical under gravity and rotates on the counterweight crossbar 701. If the tilt angle becomes too large, the swing arm 703 will cause the swing switch 704 on the tilting side to press the stop bar 702 on the same side. At this time, the electric air pump connected to the air intake pipe 105 can quickly inflate the air. Under the action of air pressure, the lifting plate 501 will move down, which can squeeze the seawater out of the water tank 101 on the same side. During the process, the lower baffle 205 is pushed down by the pressure and separated from the liquid inlet grate 103. The tension spring 204 can be elastically adapted. When the ship returns to normal stability, the swing switch 704 will no longer be pressed. After the electric air pump connected to the air intake pipe 105 loses power, it will no longer be able to continue to provide air pressure. The lifting plate 501 can continue to move up and down with the liquid level inside the water tank 101, ensuring practicality.
