Description

Technical Field

[0001] The invention relates to the technical field of bilge water main pipes, in particular to a bilge water collecting main pipe for a passenger ship. Background Art

[0002] Bilge water refers to the accumulated water on the bilge during transportation due to leakage of the outer plate, inadequate watertightness of the hatch cover, leakage of the pipeline, leakage of the stuffing box of the stern shaft sleeve and the rudder stock sleeve, and condensation of moisture caused by temperature difference. The bilge water must be removed in time, otherwise the cargo will be damp and deteriorate, the hull structure will be rusted, and even the safety of the ship will be endangered.

[0003] The prior art mostly utilizes a bilge water collecting main pipe to pump out the bilge water when in use. However, since the bilge water is uncontrollable when it is generated, it cannot be quickly discharged when it is generated. Moreover, since the bilge water contains oil, although the prior art has filters, most of them are integrated structures that cannot follow the rise and fall of the liquid level and cannot filter the oil floating on the liquid surface. Although the filtering effect is good, the filtering processing speed is slow. Based on the deficiencies of the prior art, the present invention designs a passenger ship bilge water collecting main pipe. Summary of the invention

[0010] As a preferred technical solution of the present invention, a water distribution pipe is fixedly connected to the side wall of the bilge water main pipe, a second pump is fixedly connected to one end of the bilge water main pipe, and a drain pipe is fixedly connected to the water outlet end of the second pump.

[0011] As a preferred technical solution of the present invention, the oil filter plate is arranged in front of the through groove, the second float floats on the water surface and the front end of the oil filter plate is lower than the water surface, and the lifting slide plate is slidably connected to the lifting rod.

[0012] As a preferred technical solution of the present invention, the top of the pressure rod is connected to the pressure-sensitive switch, the bottom of the liquid extraction head is provided with a water extraction port, the bottom of the liquid extraction head does not contact the bottom of the inner cavity of the hull and there is a gap, and the fixing plate is fixedly connected to the bottom of the inner cavity of the hull.

[0013] As a preferred technical solution of the present invention, one end of the water distribution pipe is fixedly connected to the water outlet end at the top of the pumping head, one end of the bilge water main pipe is connected to the water inlet end of the second pump, and one end of the drain pipe passes through the cover plate and extends to the bottom of the inner cavity of the oil filter box.

[0014] As a preferred technical solution of the present invention, the transverse cabin plate is fixedly connected to both sides of the longitudinal cabin plate.

[0015] As a preferred technical solution of the present invention, the outer end of the drain pipe is plugged into the drain hole, and the other end of the pump water pipe is fixedly plugged into the water outlet hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The bilge water collecting main pipe of the passenger ship pumps the bilge water into the oil filter box through the discharge pipe through the second pump. The bilge water carrying oil is intercepted by the oil filter pan in the oil filter box and temporarily stored, and the liquid level continues to rise. When the liquid level is higher than the front end of the oil filter pan, the bilge water and the oil floating on the liquid surface enter the oil filter pan. At this time, the oil filter plate intercepts the oil, and the bilge water moves to the other side of the oil filter pan through the oil filter plate and the through groove. When the water level of the bilge water rises after filtering on the other side and contacts the second float ball, the second float ball moves up due to the rising water level. The ball drives the oil filter pan connected to it to move upward, so that the water levels on both sides of the oil filter pan remain connected. Since the notch at the front end of the oil filter pan is lower than the position of the second float, the front end of the oil filter pan is lower than the water surface after the second float floats. At this time, the relatively clean bilge water passes through the bottom of the oil filter pan, while the oil and bilge water floating on the water surface enter the oil filter pan and are collected and filtered by the oil filter plate to separate the bilge water from the oil. Finally, the first pump is started to discharge the bilge water in the oil filter box. This device is convenient for filtering and discharging bilge water.

[0018] 2. The bilge water collecting main pipe of the passenger ship is in standby state when the pressure sensitive switch is not turned on. When water enters the cabin of the hull, the water level rises slowly in the cabin of the hull and uses buoyancy to drive the first float ball to move upward. Since the first float ball is connected to the bottom end of the pressure rod, and the pressure rod is connected to the pressure sensitive switch under the support of the bracket, when the first float ball moves upward, the pressure rod will rotate in the limited state of the bracket and press the pressure sensitive switch downward to open the pumping head, and use the second pump machine to quickly pump out the bilge water in the cabin and send it to the water distribution pipe and the bilge water main pipe. Then the second pump machine pumps the bilge water and oil in the bilge water main pipe into the filter mechanism through the drain pipe for filtration and discharge. This device is convenient for automatic pumping of bilge water. BRIEF DESCRIPTION OF THE DRAWINGS

By providing a lifting rod 504, a fixed top plate 505, a lifting slide plate 507, a back plate 509 and a second float 510, the oil filter pan 506 can move along with the rise and fall of the liquid level.

[0035] See also Figure 4-5The liquid discharge mechanism 4 includes a liquid extraction head 401, a fixed plate 402, a pressure sensitive switch 403, a bracket 404, a pressure rod 405 and a first float 406. The liquid extraction head 401 is arranged at the bottom of the inner cavity of the hull 1, the fixed plate 402 is fixedly connected to the side wall of the liquid extraction head 401, the pressure sensitive switch 403 is arranged on the top of the liquid extraction head 401, the bracket 404 is fixedly connected to the upper surface of the liquid extraction head 401, the pressure rod 405 is rotatably connected to the bracket 404, the first float 406 is fixedly connected to the outer end of the pressure rod 405, the top of the pressure rod 405 is connected to the pressure sensitive switch 403, a water extraction port is arranged at the bottom of the liquid extraction head 401, the bottom of the liquid extraction head 401 does not contact the bottom of the inner cavity of the hull 1 and there is a gap, and the fixed plate 402 is fixedly connected to the bottom of the inner cavity of the hull 1.

[0036] By providing a pumping head 401 and a fixing plate 402, the pumping head 401 can be fixed to the bottom of the inner cavity of the hull 1 to quickly pump out the bilge water of the hull 1. By providing a pressure-sensitive switch 403, a bracket 404, a pressure rod 405 and a first float 406, when no bilge water is generated in the bilge of the hull 1, the pressure-sensitive switch 403 is in a closed state and the pumping head 401 does not work. If bilge water is generated in the hull 1, the first float 406 will move upward due to buoyancy and press the pressure-sensitive switch 403 to make the pumping head 401 and the second pump 302 work.

[0037] Working principle: when the passenger ship bilge water collecting main is used, in the initial state, first, the bilge plate 2, the longitudinal bilge plate 201 and the transverse bilge plate 202 are arranged at the bottom of the inner cavity of the hull 1, and the water inlet and outlet ends of the first pump 102 arranged on the upper surface of the bilge plate 2 are respectively connected with the drain pipe 103 and the pump water pipe 104, and the drain pipe 103 is connected to the drain hole 101, so as to discharge the bilge water filtered in the filter mechanism 5, and the drainage mechanism 4 arranged at the bilge of the hull 1 is connected with the water distribution pipe 301, and the multiple water distribution pipes 301 are connected to the bilge water main 3 and then fixed on the second pump 302, so as to pump the bilge water, and the drainage pipe 303 arranged at the water outlet end of the second pump 302 penetrates the cover plate 502 and extends to the oil filter box 501, so as to send the pumped bilge water into the filter mechanism 5 for oil-water separation and filtration treatment;

[0038] When it is necessary to filter and discharge the bilge water, first the second pump 302 pumps the bilge water into the oil filter box 501 through the discharge pipe 303. The bilge water carrying oil is intercepted and temporarily stored by the oil filter pan 506 in the oil filter box 501, and the liquid level continues to rise. When the liquid level is higher than the front end of the oil filter pan 506, the bilge water and the oil floating on the liquid surface enter the oil filter pan 506. At this time, the oil filter plate 512 intercepts the oil, and the bilge water moves to the other side of the oil filter pan 506 through the oil filter plate 512 and the through groove 508. When the water level of the bilge water rises after filtering on the other side and contacts the second float 510, the second float 510 moves up due to the rising water level. The float 510 drives the oil filter pan 506 connected thereto to move upward, so that the water levels on both sides of the oil filter pan 506 remain connected. Since the front end notch of the oil filter pan 506 is lower than the position of the second float 510, the front end of the oil filter pan 506 is lower than the water surface after the second float 510 floats on the water. At this time, the relatively clean bilge water passes through the bottom of the oil filter pan 506, while the oil and bilge water floating on the water surface enter the oil filter pan 506 and are collected and filtered by the oil filter plate 512 to separate the bilge water from the oil. Finally, the first pump 102 is started to discharge the bilge water in the oil filter box 501. This device is convenient for filtering and discharging bilge water.

[0039] When it is necessary to automatically pump out the bilge water, first, when the pressure sensitive switch 403 is not turned on, the second pump 302 is in standby mode. When water enters the cabin of the hull 1, the water level slowly rises in the cabin of the hull 1 and uses buoyancy to drive the first float 406 to move upward. Since the first float 406 is connected to the bottom end of the pressure rod 405, and the pressure rod 405 is connected to the pressure sensitive switch 403 under the support of the bracket 404, when the first float 406 moves upward, the pressure rod 405 will rotate in the limited state of the bracket 404 and press the pressure sensitive switch 403 downward to open the pumping head 401, and use the second pump 302 to quickly pump out the bilge water in the cabin and send it into the water distribution pipe 301 and the bilge water main pipe 3. Then the second pump 302 pumps the bilge water and oil in the bilge water main pipe 3 into the filter mechanism 5 through the drain pipe 303 for filtration and discharge. This device is convenient for automatic pumping out of bilge water.
