Description

Technical Field

[0001] The utility model relates to the technical field of a ship lift cabin filling and draining system, in particular to a waterproof cover device for a ship lift cabin filling and draining system. Background Art

[0002] The ship lift is equipped with a cabin water level adjustment and gap filling and draining system. There are two sets of water depth adjustment and gap filling systems, which are arranged at the bottom of both ends of the cabin and in the main longitudinal beams on both sides. They are composed of pipes, electric butterfly valves, exhaust valves, check valves, submersible pumps, etc. The cabin water depth adjustment and gap filling and draining system has two functions. One is to fill and drain water into the gap area between the cabin door and the gate working door surrounded by the sealing frame during the cabin docking process; the other is to adjust the water depth of the cabin before the cabin lifting process begins. During the operation of the system, due to the high pressure, a large amount of water will be brought out when the exhaust pipe discharges air, and the overflowing water will affect the safety of the operating equipment. In order to ensure the safety of the equipment, a waterproof cover device for the cabin filling and draining system of the ship lift is installed at the end of the exhaust pipe.

[0018] Barrel body 10, through hole 11, flange 12, cone funnel 20, exhaust hole 21, drain hole 22, baffle 30, cone top cover 40, exhaust channel 41, support member 42. DETAILED DESCRIPTION

[0019] See also Figure 1-3 A waterproof cover device for a ship lift cabin filling and discharging system comprises a barrel 10, a cone funnel 20 and a cone top cover 40. The bottom of the barrel 10 is provided with a through hole 11, which is used to be installed on the end of an exhaust pipe. The inner wall of the barrel 10 is provided with a cone funnel 20, and an exhaust hole 21 is provided on the cone funnel 20. The top of the barrel 10 and the cone top cover 40 are installed on the inner side of the barrel 10, and an exhaust channel 41 is provided between the cone top cover 40 and the barrel 10. The barrel 10 is used to buffer water discharged from the exhaust pipe. The air in the exhaust pipe enters the cone funnel 20 through the exhaust hole 21. A small amount of water also enters the cone funnel 20 and is blocked from falling by the cone top cover 40. The air is discharged from the exhaust channel 41 provided between the cone top cover 40 and the barrel 10. After the exhaust is completed, the water buffered in the barrel 10 flows back into the exhaust pipe from the through hole 11. Through the above structure, it is possible to prevent a large amount of water from being discharged from the exhaust pipe when the air is discharged, thereby ensuring the safety of the equipment.

[0020] During installation, the barrel body 10 can be welded to the top end of the exhaust pipe through the through hole 11 .

[0021] Furthermore, a flange 12 is installed on the barrel body 10 at the lower side of the through hole 11 to facilitate the installation and connection between the barrel body 10 and the exhaust pipe.

[0022] When in use, a flange is also welded on the top of the exhaust pipe, so that the barrel 10 can be installed on the exhaust pipe by bolts. In order to facilitate the bolt installation, the holes on the flange 12 are threaded holes. When installing, the screws pass through the bolt holes of the flange on the top of the exhaust pipe and then are screwed with the threaded holes on the flange 12.

[0023] See also Figure 2 , 3 A baffle 30 is installed at the bottom of the cone funnel 20, the baffle 30 is located above the through hole 11, and the diameter of the baffle 30 is larger than the diameter of the through hole 11. The baffle 30 is arranged to reduce the pressure of the water when the exhaust pipe exhausts water.

[0024] When in use, water hits the bottom of the baffle 30, buffering the water and slowing down the water flow.

[0025] Furthermore, the cone funnel 20 is provided with a drainage hole 22, which is located at the bottom of the cone funnel 20, and the exhaust hole 21 is located on the upper side of the drainage hole 22, and the drainage hole 22 is connected to the baffle 30. When the exhaust pipe is exhausted and after the exhaust is completed, the water in the cone funnel 20 is conveniently discharged into the barrel body 10.

[0026] In a preferred solution, the drainage hole 22 is a long hole connected to the baffle 30, which has a better drainage effect.

[0027] See also Figure 3 , a plurality of support members 42 are installed on the top of the barrel body 10, and the conical top cover 40 is installed on the support members 42. In this solution, four support members 42 are provided, the support member 41 is welded to the inner wall of the barrel body 10, and the conical top cover 40 is welded to the support member 41. The conical top cover 40 is stably and firmly supported by the support member 41.

[0028] The working principle or action process of the utility model is as follows:

[0029] When in use, the waterproof device of the utility model is installed on the top of the exhaust pipe through the flange 12. When the air is discharged, the water first hits the baffle 30, which buffers the water and slows down the water flow. Most of the water is temporarily stored in the barrel body 10. The air in the exhaust pipe enters the cone funnel 20 through the exhaust hole 21. A small amount of water also enters the cone funnel 20 and is blocked by the cone top cover 40. The air is discharged from the exhaust channel 41 set between the cone top cover 40 and the barrel body 10. After the exhaust is completed, the water buffered in the barrel body 10 flows back into the exhaust pipe from the through hole 11.
