Description

Technical Field

[0001] The invention relates to the technical field of valve boxes, in particular to a self-sand draining valve box device for small ships. Background Art

[0002] Due to the shallow draft of small ships, when the ships take seawater, such as ballast water, cooling water, and fire water for work boats, they usually suck seawater directly from the side or the bottom. There are a lot of garbage floating on the surface of the seawater, especially there is a lot of mud and sand in the seawater near the port. After sucking it in, it is not conducive to the operation of the equipment and may even cause damage to the equipment. The current self-sand discharge valve box device for small ships is not convenient for using the valve box for sedimentation purification and sand discharge, and the filter assembly is replaced frequently. At the same time, it is not convenient to carry out comprehensive corrosion detection, especially under seawater immersion corrosion, which is easy to cause leakage hazards. It is not convenient to automatically detect corrosion points and isolate them.

At the same time, this structure uses a lower baffle 205 that can be lifted and fitted to the liquid inlet grate 103. The surface is flat and does not affect the navigation resistance of the ship. Sand removal can be carried out in real time. The downward pressure control part 3 can be used to manually control the lifting shaft 202 to lift and lower for opening and closing, which can avoid circuit problems, etc. The problem of being unable to control water intake is that when water intake is required, the electromagnet 203 can be controlled to pass through the electromagnetic suction sliding mounting block 201, and the lower baffle 205 no longer closes the liquid inlet grate 103.

After the water storage 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.

[0024] Among them, the lifting adapter 5 includes: a lifting plate 501, an internal electric column 502 and a humidifying sponge ring 503, the lifting plate 501 is slidably sleeved inside the water tank 101; the internal electric column 502 is fixedly installed on the lifting plate 501; the humidifying sponge ring 503 is sleeved on the lifting plate 501; the humidifying sponge ring 503 is attached to the inside of the water tank 101; the humidifying sponge ring 503 is attached to the internal electric column 502; the corrosion isolation part 6 includes: a pressure gas tank 601, a conduit 602 and an expansion rubber pad 603, the pressure gas tank 601 is fixedly installed on the lifting plate 501; the pressure gas tank 601 is fixedly installed There is a conduit 602; the conduit 602 passes through the lifting plate 501; a solenoid valve is arranged 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 the pressure gas tank 601; the expansion rubber pad 603 is used to expand and fit between the lifting plate 501 and the water storage tank 101; the internal electric column 502, the external electric terminal 102, the solenoid valve on the conduit 602 and the indicator light 106 are connected in series with the power supply; the corrosion isolation part 6 can be used to detect the corrosion of the inner wall of the water storage tank 101 in real time, and non-destructive testing can be achieved. At the same time, this structure utilizes the corrosion of the water storage tank 101 The conductive property of the back can be used for comprehensive detection.

This will not only affect the adjustment of the center of gravity and stability of the ship, but may also accelerate the spread of corrosion in other parts of the hull, forming a vicious circle. The galvanic corrosion and crevice corrosion caused by corrosion Etc., such as the potential difference corrosion at the contact parts of different metals, which will accelerate the damage of key components such as valves and filters. If the paint on the inner wall of the water storage tank 101 falls off, the humidifying sponge ring 503 will first contact the rusted position. At this time, the indicator light 106 can be powered on to light up as a warning, and the solenoid valve on the conduit 602 will also be energized and opened to introduce the compressed air in the pressure gas tank 601 into the expansion rubber pad 603 through the conduit 602 for sealing and isolation to prevent the rusted area from being soaked in seawater during continuous use and continued to aggravate the corrosion. The seawater remaining on the humidifying sponge ring 503 will not cause continuous corrosion to the rusted area and will gradually evaporate.

[0025] Embodiment 2. On the basis of embodiment 1, the attitude balancing weight test piece 7 comprises: a balancing weight cross bar 701, a baffle rod 702 and a swing arm 703. The balancing weight cross bar 701 is fixedly mounted on two water storage tanks 101; two baffle rods 702 are fixedly mounted on the bottom of the balancing weight cross bar 701; a swing arm 703 is rotatably mounted on the middle part of the balancing weight cross bar 701; a balancing weight ball is arranged at the bottom of the swing arm 703; the attitude balancing weight test piece 7 also comprises: a swing switch 704. Swing switches 704 are fixedly mounted on both sides of the swing arm 703, and the two swing switches 704 are electrically connected to the electric air pumps externally connected to the two air intake pipes 105 respectively; the two baffle rods 702 are aligned with the two swing switches 704 respectively. By using the attitude balancing weight test piece 7, the attitude of the ship can be detected in real time, especially for small ships. When a larger valve box water inlet structure is installed, the amount of water in the valve box directly affects the adjustment of the center of gravity and stability of the ship. This structure can detect in real time whether the attitude of the ship is tilting. When the water level is too large and drainage is performed, it can assist the ship in preventing capsizing, increase the maneuverability of the ship, and reduce safety hazards. The hull is prone to capsizing due to imbalance of inertia moment when turning, especially when the wind and waves are strong or the rudder is turned sharply, the risk is doubled. When turning, a larger seabed valve box will increase water resistance, forcing the steering gear hydraulic system to run at high load for a long time. If key components such as the hydraulic pump drive belt or crankshaft are aged, the steering gear may fail, and it is difficult to restore control in an emergency. This structure can control the lifting plate 501 to move down for drainage after real-time detection. When the ship rolls, once the roll angle is too large, the swing arm 703 will drive the swing switch 704 on the roll side to squeeze the baffle 702 on the same side. At this time, the electric air pump connected to the air intake pipe 105 can be quickly inflated, and the lifting plate 501 will move down, which can squeeze out the seawater inside the water tank 101 on the same side, and assist the ship to return to normal stability by lowering the counterweight on the tilted side.

[0026] The working principle of this embodiment is as follows: first, two holes are opened in the outer plate at the bottom of the cabin. The two water storage tanks 101 of this structure are respectively welded to the reserved holes opened in the outer plate at the bottom of the cabin for installation. When water intake is required, the electromagnet 203 can be controlled to pass through the electromagnetic suction 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 closes and fits the liquid inlet grate 103. At this time, the liquid inlet grate 103 loses its obstruction and water can be introduced to fill the water storage tank 101. After the water storage tank 101 is filled, the electromagnet 203 can be controlled to be powered off, and the tension spring 204 is pulled down, and the lower baffle 205 will close the liquid inlet grate 103. At this time, the seawater sediment impurities will naturally settle, and can also be manually rotated. The threaded rod 302 is turned and pressed down, and the lifting shaft 202 is squeezed to move downward to control the water intake. After the water storage 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 on the upper layer of the liquid surface in real time. When the water pump connected to the suction pipe 303 absorbs water, the upper water suction pipe 401 can absorb the water between the upper water suction pipe 401 and the lifting shaft 202, and then discharge it after filtering through the filter block 104. When water enters the water storage tank 101, the lifting plate 501 rises with the water level. During the process, the humidifying sponge ring 503 is soaked. At this time, if the paint surface on the inner wall of the water storage tank 101 falls off, the humidifying sponge ring 503 first contacts the rusted position, and the internal electric The column 502 forms a conductive loop with the rusted part and the external electrical terminal 102. At this time, the circuit is turned on, the indicator light 106 can be powered on and light up to warn, and at the same time, the solenoid valve on the conduit 602 will be powered on and turned on, so that the compressed air in the pressure gas tank 601 is introduced into the expansion rubber pad 603 through the conduit 602. The expansion rubber pad 603 expands rapidly and can fit between the lifting plate 501 and the water storage tank 101 for sealing and isolation. The anti-skid friction force of the expansion rubber pad 603 is used for positioning to avoid continuous aggravation of corrosion of the rusted part due to seawater immersion during continuous use. When the ship rolls due to factors such as steering, the swing arm 703 remains vertical under the action of gravity and rotates on the counterweight crossbar 701. At this time Once the roll angle is too large, the swing arm 703 will drive the swing switch 704 on the roll side to squeeze the baffle 702 on the same side. At this time, the electric air pump connected to the air inlet pipe 105 can be quickly inflated. Under the action of air pressure, the lifting plate 501 will move downward, and the seawater inside the water tank 101 on the same side can be squeezed out. During the process, the lower baffle 205 is pushed downward by the pressure and separated from the liquid inlet grate 103. The tension spring 204 can be flexibly adapted. When the ship returns to normal stability, the swing switch 704 is no longer squeezed. After losing power, the electric air pump connected to the air inlet pipe 105 can no longer provide air pressure. The lifting plate 501 can continue to move with the rise and fall of the liquid level inside the water tank 101, thereby ensuring practicality.
