Description

Technical Field

[0001] This utility model relates to the field of sealing technology for river water pipelines in ships, specifically a leak-sealing device for river water tanks. Background Technology

[0002] Existing leak-sealing devices have many drawbacks: Laborious and inefficient (troublesome): Manually opening and closing sealing covers, especially large covers or valves on large ships, requires a great deal of physical exertion from the crew.

[0003] Poor emergency response capability: In the event of an emergency requiring the valve to be shut off quickly, manual operation may be too slow to react in time.

[0004] The sealing reliability may be insufficient: manual operation cannot guarantee a constant and sufficient clamping force for each closure. Insufficient pressure may lead to a poor seal, allowing river water to slowly seep in after the cover is closed, eventually freezing in the pipeline. Excessive pressure may accelerate the wear of the sealing ring.

[0005] Remote and centralized control is not possible: manual devices require on-site operation. For large vessels, the various water release points may be scattered, requiring crew members to travel between different locations, making it impossible to complete all operations with a single button in a safe and warm location such as a central control room. Utility Model Content

[0006] In view of the deficiencies of the prior art, this utility model provides a river water tank leak-stopping device, which replaces manual control with hydraulic control, which is convenient and saves costs. The oil cylinder pushes the handle to open and close the sealing cover. After the river water is emptied, the sealing cover is closed to prevent river water from entering the water tank and pipelines. This is to prevent water in the water tank from freezing and damaging the pipelines in the ship during winter, thus preventing property damage.

[0007] To achieve the above objectives, the present invention provides a water tank leak-stopping device, comprising a starting assembly, a cover plate assembly, and a pressure rod assembly. The starting assembly is mounted on the water tank mounting platform and includes a base and a gear shaft. The base is connected to the mounting platform, and a linkage gear is fitted onto the gear shaft. Sealing structures are provided on both sides of the linkage gear, with one side of the sealing structure connected to the base and the other side connected to an outer spacer. A rack and pinion cylinder is positioned between the linkage gear and the base. The rack and pinion cylinder engages with the linkage gear to drive the linkage gear, thereby rotating the gear shaft. The cover plate assembly contacts the inlet and outlet water mains. One end of the pressure rod assembly is connected to the gear shaft, and the other end is connected to the cover plate assembly. The pressure rod assembly is positioned inside the water tank and is oscillating.

[0008] Furthermore, the sealing structure is provided with a rotary bearing, one end of which contacts the end cover and the other end of which contacts the spacer.

[0009] Furthermore, a sealing ring is provided between the end cap and the rotary bearing.

[0010] Furthermore, the rack and pinion cylinder is provided with oil port A and oil port B; oil port A supplies oil to drive the linkage gear, which in turn drives the pressure rod assembly to swing, thereby opening the cover plate assembly; oil port B supplies oil to drive the linkage gear, which in turn drives the pressure rod assembly to swing, thereby closing the cover plate assembly.

[0011] Furthermore, the pressure rod assembly is provided with a pull handle, one end of which is keyed to the gear shaft, and the other end is connected to the large ear plate; a positioning plate is provided on the pull rod near the large ear plate.

[0012] Furthermore, the cover plate assembly is provided with a small ear plate, one end of which is connected to the large ear plate and the other end of which is connected to the sealing cover; a sealing gasket is provided at the contact point between the sealing cover and the inlet / outlet water main pipe, and the sealing gasket is provided with a spring washer.

[0013] Furthermore, the outer spacer ring has a semi-circular structure.

[0014] The beneficial effects of this utility model are as follows: This application is designed for draining river water from the water tanks and pipelines of ships in winter. The existing ones are opened and closed manually, which is time-consuming and unsafe. The manual control is now replaced with hydraulic control, which is convenient and saves costs. The oil cylinder pushes the handle to open and close the sealing cover. After the river water is drained, the sealing cover is closed to prevent river water from entering the water tank and pipelines. This achieves the goal of preventing water in the water tank from freezing and damaging the pipelines on the ship in winter, thus preventing property damage. Attached Figure Description

[0017] like Figure 1-3 As shown, one embodiment of this utility model discloses a water tank leak-stopping device, including a starting assembly 100, a cover plate assembly 200, and a pressure rod assembly 300. The starting assembly 100 is disposed on the mounting platform of the water tank and is provided with a base 110 and a gear shaft 120. The base 110 is connected to the mounting platform. A linkage gear 130 is sleeved on the gear shaft 120. Sealing structures 140 are respectively provided on both sides of the linkage gear 130. One side of the sealing structure 140 is connected to the base 110. One side is connected to the gear 120, and the other side is connected to the outer spacer 150. A rack and pinion cylinder 160 is provided between the linkage gear 130 and the base 110. The rack and pinion cylinder 160 cooperates with the linkage gear 130 to drive the linkage gear 130, thereby driving the gear shaft 120 to rotate. The cover plate assembly 200 is in contact with the inlet and outlet water main pipe. One end of the pressure rod assembly 300 is connected to the gear shaft 120, and the other end is connected to the cover plate assembly 200. The pressure rod assembly 300 is set in the water tank and can swing.

[0018] In one embodiment, the sealing structure 140 is provided with a rotary bearing 141, one end of which is in contact with the end cover 142 and the other end is in contact with the spacer 143.

[0019] In one embodiment, a sealing ring 144 is provided between the end cap 142 and the rotary bearing 141.

[0020] In one embodiment, the rack and pinion cylinder 160 is provided with oil port A161 and oil port B162; oil port A161 supplies oil to drive the linkage gear 130, which in turn drives the pressure rod assembly 300 to swing, thereby opening the cover plate assembly 200; oil port B162 supplies oil to drive the linkage gear 130, which in turn drives the pressure rod assembly 300 to swing, thereby closing the cover plate assembly 200.

[0021] Furthermore, the pressure rod assembly 300 is provided with a pull handle 310, one end of which is keyed to the gear shaft 120 and the other end is connected to the large ear plate 320; a positioning plate 330 is provided on the pull rod near the large ear plate 320; the positioning plate 330 is used to prevent the cover plate assembly 200 from shaking too much and not sealing properly when closed.

[0022] It should be noted that the gear shaft 120 is connected to the key and the pull handle 310 together, thereby driving the pull handle 310 to swing, thus realizing the function of opening and closing the sealing cover 220.

[0023] In one embodiment, the cover plate assembly 200 is provided with a small ear plate 210, one end of which is connected to a large ear plate 320 and the other end is connected to a sealing cover 220; a sealing gasket 230 is provided at the contact point between the sealing cover 220 and the inlet / outlet water main pipe, and a spring washer 240 is provided on the sealing gasket 230.

[0025] In the aforementioned river water tank leak-sealing device, when opened, oil is supplied through oil port A161, the rack of the rack cylinder 160 moves to the right, driving the linkage gear 130 to rotate, which in turn drives the gear shaft 120 to rotate. The gear shaft 120 is keyed to the pull handle 310, causing the pressure rod assembly 300 to lift, opening the cover plate assembly 200 (sealing cover 220), allowing river water to enter through the inlet and outlet water main pipes. After the river water is drained, oil is supplied through oil port B162, the rack of the rack cylinder 160 moves to the left, driving the linkage gear 130 to rotate, which in turn drives the gear shaft 120 to rotate, causing the pressure rod assembly 300 to return to its starting position, closing the cover plate assembly 200 (sealing cover 220). The operation is simple and convenient. After adjusting the opening and closing angles, the limit switch is set on the base 110, and the pump station automatically stops working after reaching the position.
