Description

Technical Field

[0001] The invention belongs to the field of water surface cleaning ships, and in particular relates to a pump-suction trawling salvage ship. Background Art

[0002] In recent years, the water quality in lakes and rivers has been seriously polluted, there are many debris in the water, and the eutrophication of water bodies has aggravated the growth of aquatic plants such as water grass and water peanuts, which has brought great inconvenience to people's production and life. Coupled with the indiscriminate dumping of domestic garbage, floating objects on the water surface are drifting everywhere. There are more and more floating objects on the water surface, which seriously affects people's quality of life.

[0003] At present, the water surface cleaning of inland rivers or lakes has the following defects:

[0004] 1) Once in shallow water, pipelines, arch bridges and other areas (scenic lakes), it is difficult for cleaning boats to sail smoothly. As a result, manual salvage is more common, which is labor-intensive, inefficient and ineffective;

[0005] 2) If the cleaning ship runs aground, it cannot save itself and can only wait for rescue;

[0006] 3) The area to be cleaned was not divided into salvage areas, resulting in serious repeated salvage, further increasing the salvage cost;

[0007] 4) The layout of each compartment of the hull is very important, especially when the hull sinks to the designed water level for salvage. Once the longitudinal ballast cannot be balanced, it will be difficult to accurately reach the designed water level, the center of gravity of the hull will be unstable, and it will be unfavorable for the navigation of the hull. Summary of the invention

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new pump-suction trawling salvage vessel.

[0009] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0010] A pump-suction trawling and salvaging vessel comprises a hull and a propulsion device, wherein the hull comprises a collecting tank; closed tanks located on both sides of the collecting tank; a water tank, an empty tank and a stern empty tank arranged in sequence between the collecting tank and the stern; a guide boat placement tank arranged at the front end of the hull; two guide boats placed in the guide boat placement tank; and a waterway assembly, wherein a water filter cavity is formed between the collecting tank and the bottom of the ship, the waterway assembly comprises a drainage pipeline with one end connected to the water filter cavity and the other end connected to the outside from the side of the hull; a water pump arranged on the drainage pipeline; a water filling pipeline connected to the drainage pipeline and the water tank and penetrating from the water tank into the empty tank, and a water filling valve arranged on the water filling pipeline and located in the empty tank, the water inlet end of the water filling pipeline being connected to the outside from the bottom or side of the empty tank.

[0011] Preferably, the collection cabin includes a cabin bottom plate, cabin side plates formed on the cabin bottom plate, and a hatch door that can be flipped open or closed and is arranged at the front end of the cabin bottom plate, wherein the cabin bottom plate includes a receiving plate that is connected to the guide ship placement cabin and is arranged obliquely from top to bottom, and a water filtering mesh plate that extends horizontally from the bottom of the receiving plate to the middle of the hull, and the hatch door is arranged on the receiving plate. Here, it is further explained that the height of the collection cabin should be lower than the guide ship placement cabin, so that the backflow of floating objects collected in the collection cabin can be effectively prevented, and at the same time, under the inclined guidance, it is also convenient for floating objects to be transmitted to the inside of the collection cabin.

[0012] According to a specific implementation and preferred aspect of the present invention, the hatch includes a baffle fixed in the pilot ship placement cabin, a door panel flipped and set on the receiving plate through a sealing connector, and a door opening assembly, wherein when the hatch is closed, the door panel abuts against the baffle; when the hatch is opened, the door panel flips inward and fits on the receiving plate, and the collected materials enter the pilot ship placement cabin and flow from the surface of the door panel to the collection area formed by the collection cabin. In this way, the hatch is very convenient to open and close, and at the same time, for the hatch opening mode, the door panel can also effectively guide floating objects.

[0013] Preferably, there are two baffles, which are correspondingly arranged on opposite sides of the cabin bottom plate, wherein a sealing strip is formed on the end surface of each baffle that contacts the door panel, so as to not only form a sealing interception, but also avoid the inflow of floating objects.

[0014] Specifically, the door opening assembly includes a pulley, a traction rope, and a reel, wherein one end of the traction rope is connected to the reel, and the other end is passed around the pulley in turn and connected to the door panel. When the reel reels the rope, the traction rope pulls the door panel to contact the sealing strip; when the reel releases the rope, the door panel can flip freely into the collection area.

[0015] Furthermore, after the door panel is opened, the angle formed between the surface of the door panel and the surface of the water filter mesh plate is an obtuse angle. This not only avoids the obstacle of floating object collection after the door panel is opened; at the same time, under the guidance of the door panel, it is easy for floating objects to gather inwards, and it can also prevent floating objects entering the collection cabin from flowing back outwards.

[0016] According to another specific implementation and preferred aspect of the present invention, the water filling pipeline includes a first water filling pipe having one end connected to the outside and the other end connected to the drainage pipeline; a second water filling pipe for connecting the first water filling pipe to the water tank, and the water filling valve is arranged on the first water filling pipe. In this way, when the hull sinks to the designed water level, the water tank and the collection tank are filled with water at the same time, and during the salvage and collection, the water tank and the collection tank are pumped out of water at the same time. Therefore, in the whole process, the longitudinal ballast is balanced, thereby facilitating the operation of the hull.

[0017] Preferably, the water filling pipeline further comprises an interception filter screen arranged at the water inlet end of the first water filling pipe, thereby ensuring that the water poured into the hull is relatively clean and extending the service life of the water pump.

[0018] In addition, the hull also includes mechanical and electrical equipment compartments on both sides of the water tank. These layouts are more for the balance of the hull when working or sailing.

[0019] Preferably, the guide ship placement cabin includes a cabin body sunken downward from the bow, and two interception doors located on both sides of the cabin body and capable of rotating inward and outward from the cabin body, wherein when the guide ship is placed in the cabin body, the two interception doors intercept the front end of the cabin body; when the guide ship divides the salvage area, the two interception doors are relatively open to the outside of the cabin body.

[0020] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0021] On the one hand, the layout of each compartment of the present invention is small in volume, especially the front and rear distribution of the collection compartment and the water compartment, and the collection compartment and the water compartment can also take in and discharge water synchronously, thereby ensuring the longitudinal ballast balance of the hull; on the other hand, the salvage area is divided by guiding the ship, which greatly improves the salvage efficiency and salvage effect. At the same time, even if it runs aground, it can also discharge water at the same time so that the hull can float steadily for self-rescue, which is very suitable for cleaning inland rivers or lakes.

[0032] like Figure 1 As shown, the pump-suction trawling salvage vessel of this embodiment comprises a hull 1 and a propulsion device 2, wherein the propulsion device 2 is located at the stern.

[0033] Combination Figure 2 As shown, the hull 1 includes a collecting tank 10; a closed tank 11 located on both sides of the collecting tank 10; a water tank 12, an empty tank 13 and a stern empty tank 14 arranged in sequence between the collecting tank 10 and the stern; a guide boat placement tank 15 arranged at the front end of the hull; two guide boats 16 placed in the guide boat placement tank 15; a waterway component 17; and an electromechanical equipment compartment 18 located on both sides of the water tank 12.

[0034] Specifically, a water filtering chamber q is formed between the collecting tank 10 and the bottom of the ship. In this example, the collecting tank 10 includes a tank bottom plate 100, a tank side plate 101 formed on the tank bottom plate 100, and a hatch 102 which is arranged at the front end of the tank bottom plate 100 and can be flipped open or closed.

[0035] The cabin bottom plate 100 includes a receiving plate a connected to the guide boat placement cabin 15 and arranged obliquely from top to bottom, and a water filtering mesh plate b extending horizontally from the bottom of the receiving plate a to the middle of the hull.

[0036] Meanwhile, three side panels 101 are arranged around the bottom panel 100, and a water filtering hole is formed on each side panel 101. In this way, when the collecting cabin 10 is installed, not only the bottom panel 100 is separated from the bottom of the ship, but also the side panels 101 are separated from the side walls of the cabin body, so that water can be filtered better.

[0037] In this example, the hatch 102 is arranged on the receiving plate a. Here, it is further explained that the height of the collection cabin should be lower than the placement cabin of the guide ship, so that the backflow of the floating objects collected in the collection cabin can be effectively prevented, and at the same time, under the inclined guidance, the floating objects are also easily transferred to the inside of the collection cabin.

[0038] Specifically, the hatch 102 includes a baffle c fixed in the guide ship placement cabin 15, a door panel e flipped and set on the receiving plate a through a sealing connector d, and a door opening assembly f, wherein when the hatch 102 is closed, the door panel e abuts against the baffle c; when the hatch 102 is opened, the door panel e flips inward and fits on the receiving plate a, and the collected objects enter from the guide ship placement cabin 15 and flow from the surface of the door panel e to the collection area formed by the collection cabin 10. In this way, the hatch is very convenient to open and close, and at the same time, for the hatch opening mode, the door panel can also effectively guide the floating objects.

[0039] There are two baffles c, which are correspondingly arranged on opposite sides of the cabin bottom plate 100, wherein a sealing strip g is formed on the end surface where each baffle c contacts the door panel e, which not only forms a sealing interception, but also can prevent the inflow of floating objects.

[0040] Specifically, the door opening assembly f includes a pulley f1, a traction rope f2, and a reel f3, wherein one end of the traction rope f2 is connected to the reel f3, and the other end is passed around the pulley f1 in turn and connected to the door panel e. When the reel f3 reels the rope, the traction rope f2 pulls the door panel e to contact the sealing strip g; when the reel f3 releases the rope, the door panel e is free to flip into the collection area.

[0041] As for the winder f3, it can be operated manually or automatically.

[0042] After the door panel e is opened, the angle formed between the surface of the door panel e and the surface of the filter mesh panel b is an obtuse angle. This not only avoids the obstacle of floating object collection after the door panel is opened; at the same time, under the guidance of the door panel fitting, it is easy for floating objects to gather inwards, and it can also prevent floating objects entering the collection chamber from flowing back outwards.

[0043] The water circuit assembly 17 includes a drainage pipe 170 having one end connected to the water filter chamber q and the other end connected to the outside from the side of the hull; a water pump (submersible pump) 171 arranged on the drainage pipe 170; a water filling pipe 172 connected to the drainage pipe 170 and the water tank 12 and penetrating from the water tank 12 into the empty tank 13; and a water filling valve 173 arranged on the water filling pipe 172 and located in the empty tank 13, wherein the water inlet end of the water filling pipe 172 is connected to the outside from the bottom or side of the empty tank 13.

[0044] The water filling pipeline 172 includes a first water filling pipe h, one end of which is connected to the outside and the other end of which is connected to the drainage pipeline 170; a second water filling pipe j for connecting the first water filling pipe h to the water tank 12, and a water filling valve 173 is arranged on the first water filling pipe h. In this way, when the hull sinks to the designed water level, the water tank and the collection tank are filled with water at the same time, and during the salvage and collection, the water tank and the collection tank are pumped out of water at the same time. Therefore, in the whole process, the longitudinal ballast is balanced, thereby facilitating the operation of the hull.

[0045] At the same time, the water filling pipeline 172 also includes an interception filter k arranged at the water inlet end of the first water filling pipe h, thereby ensuring that the water poured into the hull is relatively clean and extending the service life of the water pump.

[0046] In addition, the guide ship placement cabin 15 includes a cabin 150 that is sunken downward from the bow, and two interception doors 151 located on both sides of the cabin 150 and capable of rotating inward and outward of the cabin 150, wherein when the guide ship 16 is placed in the cabin 150, the two interception doors 151 intercept the front end of the cabin 150; when the guide ship 16 divides the salvage area, the two interception doors 151 are relatively open to the outside of the cabin 150.

[0047] As for the guide boat 16, which is an electric boat with automatic power, the salvage area is mainly divided by the guide boat 16 and the guide rope, thereby improving the cleaning efficiency and cleaning effect of the water area to be cleaned.

[0048] In summary, this implementation has the following advantages:

[0049] 1. The longitudinal ballast balance of the hull is ensured by the layout of each tank, especially the front and rear distribution of the collection tank and the water tank, and the collection tank and the water tank can also be filled with water and drained synchronously;

[0050] 2. Guide the ship to divide the salvage area, greatly improving the salvage efficiency and effect.

[0051] 3. Even if it runs aground, it can also drain water to make the hull float steadily for self-rescue, which is very suitable for cleaning in inland rivers or lakes;

[0052] 4. The hatch is very convenient to open and close. The angle of the door panel after opening the door not only facilitates the gathering of floating objects into the collection cabin, but also prevents the floating objects from flowing back.

[0053] 5. The filling valve is located in the empty compartment, which is convenient for inspection and maintenance.

[0054] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them. It does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
