Description

Technical Field

[0001] This utility model relates to the field of vent pipe technology, and in particular to a novel marine vent pipe with a liquid level switch. Background Technology

[0002] In ship design and construction, the ventilation system and liquid level monitoring system of the compartments are crucial components for ensuring the safe operation of the vessel. Traditionally, ship compartments typically design and install vent pipes and liquid level float switches as two separate systems, requiring independent through-holes in the bulkhead and the installation of their respective access components. This separate design not only increases the number of openings in the bulkhead but also increases the workload of on-site welding and installation, leading to longer construction periods and higher construction costs.

[0003] Furthermore, since the two systems are installed independently, problems such as location conflicts and unreasonable layouts can easily occur, affecting the optimal utilization of the ship's internal space. Traditional liquid level float switches are mostly side-mounted or independently top-mounted, which are complex in structure and inconvenient to maintain. Moreover, the integration of liquid level detection equipment is not fully considered in the venting pipeline system, resulting in functional dispersion and poor overall integrity. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a new type of marine combined vent pipe with liquid level switch.

[0005] The technical problem to be solved by this utility model is to provide a new type of marine combined vent pipe with liquid level switch to solve the problems of complex structure and inconvenient maintenance of existing pipes.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A novel marine venting pipe with a liquid level switch includes: a top-mounted float, a fixing component mounted on the top-mounted float, a fixing plate mounted on the outer wall of the fixing component, a single-sided seat plate fixedly connected to the bottom of the fixing plate, a venting main pipe fixedly connected to the bottom of the single-sided seat plate, a seamless steel pipe inserted into the outer wall of the venting main pipe, and a connecting flange fixedly mounted on the outer wall of the seamless steel pipe.

[0007] Preferably, the fixing component includes a fixing sleeve, which is fitted onto the outer wall of the top-mounted float and is fixedly connected to the inner wall of the fixing plate. A plurality of plum blossom bolts are also threaded through the outer wall of the fixing sleeve, with one end of each plum blossom bolt abutting against the outer wall of the top-mounted float.

[0008] Preferably, the fixing component further includes two arc-shaped plates, both of which are movably installed below the fixing sleeve, and side blocks are fixedly connected to the outer walls of both arc-shaped plates, with a common bolt installed on the two side blocks.

[0009] Preferably, a round shaft is rotatably connected through both of the arc-shaped plates, and one end of the round shaft is fixedly connected to the bottom of the fixed sleeve.

[0010] Preferably, an anti-slip pad is fixedly connected to the inner wall of the arc-shaped plate, and the anti-slip pad is in contact with the outer wall of the top-mounted float.

[0011] Preferably, multiple bolts are fixedly installed between the fixing plate and the single-sided seat plate.

[0012] Preferably, an outer reinforcing ring is fixedly connected between the outer wall of the ventilating main pipe and the bottom of the single-sided seat plate, and an inner reinforcing ring is fixedly connected between the inner wall of the ventilating main pipe and the bottom of the single-sided seat plate.

[0013] In the above solution, the liquid level float switch and the venting pipeline are integrated into one unit, and a top-mounted float is installed through a single-sided seat plate on the top of the venting main pipe, thus achieving an organic combination of liquid level detection and venting functions. This design avoids the problem of needing to drill holes in the bulkhead to install independent components as in traditional solutions, significantly reducing the number of holes and welding workload.

[0014] In the above scheme, the main ventilation pipe adopts an enlarged design, which can still ensure sufficient ventilation area even after the float is installed inside, ensuring smooth ventilation of the cabin; the side is equipped with a seamless steel pipe branch pipe with a connecting flange, which facilitates connection with the external ventilation pipeline and the system has strong compatibility.

[0015] In the above scheme, the fixed plate and the single-sided seat plate are connected by bolts, and the fixed components clamp the float with the arc plate by plum blossom bolts. The structure is easy to disassemble and assemble, supports on-site prefabrication and overall hoisting, greatly shortens the on-site installation time, and improves the efficiency of ship construction.
