[0002] Ship's fresh water tank is used to store fresh water supplied by ship desalination equipment manufacturing or shore-based and other ships. The water in the fresh water tank is pumped out through the water suction port and pipes installed in the tank, and is used for ship kitchen water, crew washing, laundry, toilet flushing and other domestic water, as well as fresh water circulation cooling for ship's main engine, auxiliary machinery and other equipment. After a period of use, the ship's fresh water tank will gradually accumulate rust and sediment in the water due to aging of the fresh water equipment, defects in the water production process, corrosion of the pipes and the inner wall of the water tank. However, the water suction port in the existing fresh water tank is generally fixed at a position about 10 centimeters from the bottom of the tank, and the pipe is fixed on the side wall of the fresh water tank. When the water in the fresh water tank is pumped out through the water suction port, the rust and sediment deposited on the bottom of the tank will be stirred, causing the pumped water to be turbid and difficult to use normally, which can easily affect the health of the crew and reduce the service life of the ship's equipment. At the same time, to reduce the impact of sediment and rust deposited in the fresh water tank, the fresh water tank needs to be cleaned regularly to pump out the water in the fresh water tank and clean out the rust and sediment deposited on the bottom of the tank. However, when using the water suction port to pump out the water from the fresh water tank, the water at the bottom of the tank is difficult to pump out due to the certain height distance between the water suction port and the tank bottom. Therefore, temporary water pumps and pipelines need to be installed for pumping out the water, making the existing fresh water tank suction device extremely inconvenient to use.

[0022] Ship's fresh water tank is used to store fresh water supplied by ship desalination equipment manufacturing or shore-based and other ships. The water in the fresh water tank is pumped out through the water suction port and pipes installed in the tank, and is used for ship kitchen water, crew washing, laundry, toilet flushing and other domestic water, as well as fresh water circulation cooling for ship's main engine, auxiliary machinery and other equipment. After a period of use, the ship's fresh water tank will gradually accumulate rust and sediment in the water due to aging of the fresh water equipment, defects in the water production process, corrosion of the pipes and the inner wall of the water tank. However, the water suction port in the existing fresh water tank is generally fixed at a position about 10 centimeters from the bottom of the tank, and the pipe is fixed on the side wall of the fresh water tank. When the water in the fresh water tank is pumped out through the water suction port, the rust and sediment deposited on the bottom of the tank will be stirred, causing the pumped water to be turbid and difficult to use normally, which can easily affect the health of the crew and reduce the service life of the ship's equipment. At the same time, to reduce the impact of sediment and rust deposited in the fresh water tank, the fresh water tank needs to be cleaned regularly to pump out the water in the fresh water tank and clean out the rust and sediment deposited on the bottom of the tank. However, when using the water suction port to pump out the water from the fresh water tank, the water at the bottom of the tank is difficult to pump out due to the certain height distance between the water suction port and the tank bottom. Therefore, temporary water pumps and pipelines need to be installed for pumping out the water, making the existing fresh water tank suction device extremely inconvenient to use.

[0023] Based on the above problems, the embodiment of the present invention provides a floating water suction device suitable for a water tank or a liquid tank. The device is used in conjunction with the buoyancy box and the water suction bell of the floating water suction bell through a telescopic traction rod, so that the water suction bell can automatically adjust its height as the water level rises and falls, so that the water suction bell floats on the water surface and the water suction port is immersed in water. It always starts to absorb water from the upper layer of the water in the fresh water tank, avoiding the inhalation of rust and mud deposited on the bottom of the tank. During the operation of cleaning the fresh water tank, the water suction bell can drain the accumulated water on the bottom of the tank, which is convenient for cleaning, opening inspection and maintenance of the fresh water tank, ensuring daily water suction use and fresh water tank cleaning operations, and improving the convenience of using the water suction device in the fresh water tank. The water suction device of the present invention is easy to use, has good effects, is highly practical, and is worthy of promotion.

[0024] Reference Figure 1 , Figure 1 This is a schematic structural diagram of the floating water absorbing device of this embodiment. Figure 1 As shown, a floating water suction device suitable for a water tank or a liquid tank comprises a telescopic traction rod 1 arranged in a fresh water tank 10 of a ship, one end of the telescopic traction rod 1 is hinged to the side wall of the fresh water tank 10 through a first hinge 11, and the hinge axis of the first hinge 11 is arranged in the horizontal direction. Figure 4 , Figure 4 It is a three-dimensional diagram of the water-absorbing clock of this embodiment, as shown in FIG. Figure 4 As shown, the floating water absorption bell 2 includes a water absorption bell 22 and a buoyancy box 21. The water absorption bell 22 is hinged to the other end of the telescopic traction rod 1 through a second hinge 23. The hinge axis of the second hinge 23 is parallel to the hinge axis of the first hinge 11. The water absorption bell 22 is provided with a hollow inner cavity. The water suction port is provided at the bottom of the water absorption bell and is connected with the hollow inner cavity. The water pump outside the fresh water tank 10 is connected with the hollow inner cavity through a pipeline. The buoyancy box 21 is fixed on the top of the water absorption bell 22 so that the water absorption bell 22 floats on the water surface of the fresh water tank 10 and the water suction port is immersed in water.

[0025] Reference Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the water-absorbing clock in the middle state of this embodiment. Figure 3 This is a schematic diagram of the water-absorbing clock in the present embodiment in a water-free state. Figure 2 、 3As shown, the floating water suction device proposed in this embodiment uses a telescopic traction rod 1 to cooperate with the buoyancy box 21 of the floating water suction bell 2 and the water suction bell 22. During the daily water suction process, the water suction bell 22 can automatically adjust its height as the water level rises and falls, always floating on the water surface in the cabin, sucking water from the middle and upper layers of the cabin, avoiding stirring up rust and mud deposited on the bottom of the cabin, causing the water pumped out from the fresh water tank to be turbid. During the fresh water tank cleaning operation, the water suction bell 22 continues to descend with the water level, and the water suction port at its bottom can be used to drain the accumulated water at the bottom of the cabin as much as possible, without the need to temporarily configure water pumps and pipelines for pumping and drainage, which facilitates the cleaning, opening inspection and maintenance of the fresh water tank, thereby effectively improving the convenience of using the water suction device in the fresh water tank.

[0026] In this embodiment, the telescopic traction rod 1 includes a first rod body and a second rod body that are slidably mounted. The outer end of the first rod body is connected to the side wall of the fresh water tank through a first hinge 11, and the outer end of the second rod body is connected to the water suction bell 22 through a second hinge 23.

[0027] As a further optimization solution, in this embodiment, the longitudinal section of the buoyancy box 21 is V-shaped, and the width of the buoyancy box 21 gradually increases from one end close to the water absorption bell 22 to the other end.

[0028] In this embodiment, a buoyancy tank 21 with a V-shaped longitudinal section is used, so that the water absorption bell 22 can float stably on the water surface in the cabin and does not float around with the shaking of the liquid surface in the cabin. It is suitable for use during ship navigation and improves ease of use.

[0029] Reference Figure 5 and Figure 6 , Figure 5 This is a front view of the water-absorbing clock of this embodiment. Figure 6 This is the back view of the water-absorbing bell of this embodiment, as shown in FIG. Figure 5 、 6 As shown, as a further optimization solution, the longitudinal section of the water absorption bell 22 in this embodiment is V-shaped, and the width of the water absorption bell 22 gradually increases from one end close to the float box 21 to the other end.

[0030] In this embodiment, a water absorption bell 22 with a V-shaped longitudinal section is used to increase the area of ​​the water absorption port at the bottom, which can effectively ensure the efficiency of water absorption. When there is less water accumulation on the site, the water can be pumped out as cleanly as possible, further improving the convenience of use.

[0031] In this embodiment, the water suction bell 22 is provided with a water outlet at one end (in the length direction), and an elbow is installed on the water outlet. The elbow has a rotary joint, and the elbow is connected to the external water suction pipe through a hose. The water suction bell 22 is connected to the telescopic traction rod through the first hinge 11 at the other end (in the length direction).

[0032] The floating water suction device in this embodiment can be installed at a selected construction point on the existing fixed water suction pipeline in the cabin. A flange plate can be installed at this point (or the existing flange plate can be used), and then the dynamic floating water suction device can be installed. During installation, there is no need to make extensive modifications to the existing bulkheads and pipelines. The preliminary processing and production of the floating water suction device can be completed in the workshop. After installation in the cabin, the elbow is connected to the existing fixed water suction pipeline in the cabin using a hose.

[0033] As a further optimization solution, in this embodiment, the inclined surfaces on both sides of the water absorption bell 22 are located directly below the inclined surfaces on both sides of the float box 21.

[0034] In this embodiment, the water absorption bell 22 with a V-shaped longitudinal section and the inclined surface of the float box 21 are arranged opposite each other, so that the middle of the entire floating water absorption bell 2 is small and the upper and lower ends are large, which can further improve the stability of the floating water absorption bell 2 floating on the water surface.

[0035] As a further optimization solution, in this embodiment, the second hinge 23 is a universal hinge or a ball hinge.

[0036] In this embodiment, the telescopic traction rod is connected to the water absorption bell by a universal hinge or a ball hinge, so that when the water absorption bell 22 automatically adjusts its height as the water level rises and falls, the water absorption bell always remains in a vertical state, ensuring that the water suction port at the bottom of the water absorption bell 22 is always in the water.

[0037] Reference Figure 9 , Figure 9 This is a schematic diagram of the structure of the support base of this embodiment, as shown in FIG. Figure 9 As shown, as a further optimization solution, in this embodiment, it also includes a support base 3 fixedly connected to the side wall of the fresh water tank 10, one end of the telescopic traction rod 1 is hinged to the support base 3 through a first hinge 11, and two outward-extending limit plates 31 are fixed on the upper and lower sides of the support base 3. The two limit plates 31 are symmetrically arranged with the hinge axis of the first hinge 11 as the center, so that the rotation angle range of the telescopic traction rod 1 around the first hinge 11 is less than 180°.

[0038] In this embodiment, the telescopic traction rod 1 is installed on the side wall of the fresh water tank 10 using a support base 3, and then the limit plate 31 is used to limit the rotation angle of the telescopic traction rod 1, so that the rotation range of the telescopic traction rod 1 is between the vertical upward and vertical downward sides, which plays a role in limiting the telescopic traction rod from reaching the upper and lower vertical positions, so as to prevent the water absorption bell from falling back and getting stuck.

[0039] Reference Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of the telescopic traction rod shortened in this embodiment. Figure 8 This is a schematic diagram of the structure of the telescopic traction rod extending in this embodiment. Figure 7 、8 As shown, in this embodiment, the water absorption bell 22 uses the telescopic traction rod 1 to float up and down. When the telescopic traction rod is nearly vertically downward and fully extended, the water absorption bell should just touch the bottom of the cabin to achieve maximum water absorption and water emptying functions.

[0040] ( Figure 1 The fixed pipe 12 in the middle is the original suction pipe fixed in the tank. When using the original fixed pipe 12 in the fresh water tank, it is only necessary to remove the flange connection on the original pipe in the water tank (if the location is suitable), or cut a new opening in the original pipe and add a flange, or extend the pipe on the original pipe and add a flange, and then use a hose to connect the flange and the elbow on the suction bell 22. This avoids unnecessary construction and modification and is the most feasible. The best effect of the above construction modification is to make the height of the flange of the original pipe after modification approximately in the middle of the water tank. In this way, the support base 3 remains horizontally aligned with the flange and is fixed to the side bulkhead. The upward and downward strokes of the suction bell are consistent, and the length of the hose is easy to control, so that the equipment can perform optimally.

[0041] In addition, an elbow pipeline is welded on the flange on the existing water suction pipe. The elbow pipeline has a rotary joint, which facilitates the connection between the end of the hose away from the elbow on the water suction bell 22 and the elbow on the flange.

[0042] Under the buoyancy of the float box on the top of the floating water absorption bell, the water absorption bell always floats on the water surface and the water suction port is immersed in the water; under the traction of the telescopic traction rod, the floating water absorption bell can move from nearly vertical upward to nearly vertical downward, and the telescopic traction rod can be freely extended and retracted, which expands the vertical movement distance of the floating water absorption bell and avoids being restricted by horizontal distance space.

[0043] In the case where mud, sand and rust are deposited on the bottom of the inner side of the fresh water tank, after installing and using the dynamic floating water suction device provided by the utility model, during normal water suction use, the water suction port in the tank can be automatically and fully maintained at a relatively high position to avoid sucking in water with impurities or a lot of impurities from the lower part or bottom of the water tank; during the water tank cleaning operation, the accumulated water and impurities in the tank can be drained out together as needed.

[0044] The above disclosure is only a preferred specific embodiment of the present invention, but the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the scope of protection of the present invention.
