Description

Technical Field

[0001] The present application relates to the field of seawater filtration, and in particular to a seawater filtration mechanism for an emergency command boat. Background Art

[0002] A command boat is a vessel used by the public security department to perform special duty tasks. During navigation, the command boat usually needs to pump seawater into the hull to work and filter out certain foreign matter in the seawater through the filter inside the hull.

[0003] During the driving process, the command boat needs to filter and inhale seawater to maintain part of its work. However, there are many microorganisms or plants in the seawater. Seawater continues to enter the command boat. The filtered solids are retained in the pipeline under the action of the flowing seawater, causing the pipeline to be blocked. Therefore, there is room for improvement. Utility Model Content

[0004] In order to reduce the occurrence of filtered solids being retained in the pipeline, the present application provides a seawater filtering mechanism for an emergency command boat.

[0005] The seawater filtration mechanism of the emergency command boat provided in this application adopts the following technical solution:

[0006] A seawater filtering mechanism for an emergency command boat comprises a water inlet pipe, one side of the water inlet pipe is a water inlet, one end of the water inlet pipe located at the water inlet is connected to a filter screen, the filter screen is arranged in an arc shape, and the distance between the side of the filter screen away from the water inlet pipe and the water inlet pipe increases from the edge to the middle of the filter screen.

[0007] By adopting the above technical solution, seawater enters the water inlet pipe through the filter, and impurities are filtered by the filter. At this time, the required seawater enters the water tank of the command boat through the water inlet pipe, and the impurities are flushed by the seawater in the arc structure of the filter and returned to the sea along the arc outer wall; the filter is set at the end of the water inlet pipe, and the arc filter is used to guide the impurities into the seawater smoothly, thereby reducing the occurrence of filtered solids being retained in the pipe.

[0008] Optionally, a protective sheet is provided on a side of the filter screen away from the water inlet pipe, and a clamping block is provided on an end of the protective sheet close to the filter screen, and the clamping block can be clamped in the middle of the filter screen.

[0009] Optionally, the protective sheet is configured to be arc-shaped, and the arc of the protective sheet is the same as the arc of the filter screen.

[0010] By adopting the above technical solution, when impurities come into contact with the protective plate, they can be guided into the seawater under its own arc-shaped guide, thereby reducing the impurities remaining in the middle of the filter when the seawater passes through the filter. The middle of the filter has a smaller arc and is difficult to guide into the seawater, which leads to serious blockage. Therefore, an arc-shaped protective plate is used to reduce the blockage of impurities in the filter and increase the pressure on the filter.

[0011] Optionally, the filter screen is threadedly connected to the water inlet pipe, a loading and unloading groove is provided on the periphery of the filter screen, a loading and unloading block is provided on the periphery of the protective sheet, and the loading and unloading block can be inserted into the loading and unloading groove.

[0012] By adopting the above technical solution, when the clamping block on the protective sheet is removed from the filter net, the loading and unloading block can be inserted into the loading and unloading groove, and the filter net can be smoothly rotated with the protruding protective sheet as a fulcrum to remove the filter net from the water inlet pipe.

[0013] Optionally, a recoil port is provided on the water inlet pipe, and a recoil elastic layer is provided at the recoil port of the water inlet pipe, the expansion area of ​​the recoil elastic layer is larger than the recoil port, the recoil elastic layer is connected to a recoil machine, and the recoil elastic layer can contact the inner wall of the water inlet pipe opposite to the recoil port.

[0014] Optionally, the distance between the recoil elastic layer and the inner wall of the water inlet pipe opposite to the recoil port is smaller than the distance between the recoil elastic layer and the filter screen; and there is a gap between the recoil elastic layer and the filter screen.

[0015] By adopting the above technical solution, after the seawater is filtered by the filter, some impurities are guided into the seawater through the arc-shaped outer wall of the filter, and some impurities are still attached to the filter. At this time, the recoil machine is started, and the recoil elastic layer is instantly inflated. The recoil elastic layer expands rapidly in the water inlet pipe, so that when it is against the inner wall of the water inlet pipe opposite to the recoil port, the seawater is quickly discharged to both sides of the water inlet pipe, and the seawater on the side of the water inlet is flushed out of the filter, so that the impurities attached to the filter are flushed out into the seawater.

[0016] Optionally, a support rod is provided at the water inlet of the water inlet pipe, one end of the support rod is connected to the inner wall of the water inlet pipe, and the other end is attached to the side wall of the filter screen close to the water inlet pipe.

[0017] Optionally, one of the support rods is attached to the middle part of the side wall of the filter screen close to the water inlet pipe, and is rotatably connected to the water inlet pipe.

[0018] By adopting the above technical solution, when the support rods are snapped in place and are in contact with the side walls of the filter, one of the support rods is in contact with the middle of the side wall of the filter close to the water inlet pipe, providing support for the middle of the filter, thereby preventing the middle of the filter and the part away from the filter frame from being dented when seawater passes through the filter, causing the arc-shaped filter to be unable to guide impurities along the arc-shaped outer wall into the seawater, thereby adhering to the filter to form a blockage.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] Seawater enters the water inlet pipe through the filter, and impurities are filtered by the filter. At this time, the required seawater enters the water tank of the command boat through the water inlet pipe. The impurities are washed by the seawater along the arc-shaped outer wall of the filter and return to the sea. The filter is set at the end of the water inlet pipe, and the arc-shaped filter is used to guide the impurities into the seawater smoothly, reducing the occurrence of filtered solids being retained in the pipe.

[0021] After the seawater is filtered by the filter, some impurities are guided into the seawater through the arc-shaped outer wall of the filter, and some impurities are still attached to the filter. At this time, the recoil machine starts to instantly inflate the recoil elastic layer. The recoil elastic layer expands rapidly in the water inlet pipe, and when it hits the inner wall of the water inlet pipe opposite to the recoil port, the seawater is quickly discharged to both sides of the water inlet pipe. The seawater on the side of the water inlet is flushed out of the filter, so that the impurities attached to the filter are flushed out into the seawater.

[0022] When the support rods are snapped in and attached to the side walls of the filter, one of the support rods is attached to the middle of the side wall of the filter close to the water inlet pipe, providing support for the middle of the filter, preventing the middle of the filter, away from the filter frame, from being dented when seawater passes through the filter, causing the arc-shaped filter to be unable to guide impurities along the arc-shaped outer wall into the seawater, thereby adhering to the filter to form a blockage.

[0026] The following is combined with Figure 1-2This application is described in further detail.

[0027] The present application embodiment discloses a seawater filtering mechanism for an emergency command boat. Figure 1 and Figure 2 The seawater filtering mechanism of the emergency command boat includes a water inlet pipe 1, which is a part of the command boat. One end of the water inlet pipe 1 is connected to a water tank in the command boat, and the other end of the water inlet pipe 1 extends into the seawater. A filter screen 2 is threadedly connected to the end of the water inlet pipe 1 extending into the seawater. In this embodiment, the filter screen 2 is made of stainless steel, the frame of the filter screen 2 is threadedly connected to the water inlet pipe 1, the mesh body of the filter screen 2 is connected to the frame of the filter screen 2, and the mesh body of the filter screen 2 is arranged in an arc shape, so that the distance between the side of the filter screen 2 away from the water inlet pipe 1 and the water inlet pipe 1 increases from the edge to the middle of the filter screen 2.

[0028] Seawater enters the water inlet pipe 1 through the filter 2, and impurities are filtered by the filter 2. At this time, the required seawater enters the water tank of the command boat through the water inlet pipe 1, and the impurities are flushed by the seawater in the arc structure of the filter 2 and return to the sea along the arc outer wall.

[0029] Reference Figure 1 and Figure 2 A support rod 13 is provided at the water inlet 11 of the water inlet pipe 1. One end of the support rod 13 is rotatably connected to the water inlet pipe 1 through an axis rod, and a snap-on key is provided at the rotatable connection. Although the support rod 13 and the water inlet pipe can be rotatably connected, when the end of the support rod 13 away from the water inlet pipe 1 is in contact with the side wall of the filter screen 2, the end of the support rod 13 close to the water inlet pipe 1 is just snapped with the water inlet pipe 1, thereby completing the fixing of the angle of the support rod 13.

[0030] When the support rods 13 are snapped in place and abut against the side walls of the filter screen 2, one of the support rods 13 abuts against the middle of the side wall of the filter screen 2 close to the water inlet pipe 1, providing support for the middle of the filter screen 2 to prevent the middle of the filter screen 2 and the part away from the frame of the filter screen 2 from being dented when seawater passes through the filter screen 2, causing the arc-shaped filter screen 2 to be unable to guide impurities along the arc-shaped outer wall into the seawater, thereby adhering to the filter screen 2 to form a blockage.

[0031] Reference Figure 1 and Figure 2 A protective sheet 3 is provided on the side of the filter screen 2 away from the water inlet pipe 1, and a clamping block 31 is integrally formed at one end of the protective sheet 3 close to the filter screen 2. The clamping block 31 can be clamped in the middle of the filter screen 2. At this time, the clamping block 31 is inserted into the mesh of the filter screen 2.

[0032] The protection sheet 3 is configured to be arc-shaped, and the arc of the protection sheet 3 is the same as the arc of the filter screen 2; when impurities come into contact with the protection sheet 3, they can be guided into the seawater under the guidance of their own arc.

[0033] The peripheral wall of the protective sheet 3 is integrally formed with a loading and unloading block 32. In this embodiment, the outer wall of the loading and unloading block 32 is also consistent with the curvature of the protective sheet 3. The peripheral part of the outer frame of the filter screen 2 is provided with a loading and unloading groove 21. When the clamping block 31 on the protective sheet 3 is removed from the filter screen 2, the loading and unloading block 32 can be inserted into the loading and unloading groove 21. With the protruding protective sheet 3 as a fulcrum, the filter screen 2 can be smoothly rotated to remove the filter screen 2 from the water inlet pipe 1.

[0034] Reference Figure 1 and Figure 2 The water inlet pipe 1 is provided with a recoil port 12, and a recoil elastic layer 4 is crimped at the recoil port 12, and the recoil elastic layer 4 is made of rubber; the expansion area of ​​the recoil elastic layer 4 is larger than the recoil port 12, and the recoil elastic layer 4 is connected to a recoil machine 41, and the recoil machine 41 is an inflator. The distance between the recoil elastic layer 4 and the inner wall of the water inlet pipe 1 opposite to the recoil port 12 is smaller than the distance between the recoil elastic layer 4 and the filter 2; there is a gap between the recoil elastic layer 4 and the filter 2.

[0035] After the seawater is filtered by the filter 2, some impurities are guided into the seawater through the arc-shaped outer wall of the filter 2, and some impurities are still attached to the filter 2. At this time, the recoil machine 41 is started, and the recoil elastic layer 4 is instantly inflated. The recoil elastic layer 4 expands rapidly in the water inlet pipe 1, so that when it abuts against the inner wall of the water inlet pipe 1 opposite to the recoil port 12, the seawater is quickly discharged to both sides of the water inlet pipe 1, and the seawater on the side of the water inlet port 11 is flushed out of the filter 2, so that the impurities attached to the filter 2 are flushed out into the seawater.

[0036] The implementation principle of the seawater filtering mechanism of an emergency command boat in the embodiment of the present application is as follows: seawater enters the water inlet pipe 1 through the filter net 2, and impurities are filtered by the filter net 2. At this time, the required seawater enters the water tank of the command boat through the water inlet pipe 1, and the impurities are flushed by the seawater along the arc-shaped outer wall of the filter net 2 and return to the sea; after the seawater is filtered by the filter net 2, some impurities are guided into the seawater through the arc-shaped outer wall of the filter net 2, and some impurities are still attached to the filter net 2. At this time, the recoil machine 41 is started, and the recoil bomb is instantly The elastic layer 4 is inflated, and the recoil elastic layer 4 expands rapidly in the water inlet pipe 1, so that when it abuts against the inner wall of the water inlet pipe 1 opposite to the recoil port 12, the seawater is quickly discharged to both sides of the water inlet pipe 1, and the seawater on the side of the water inlet port 11 is flushed out of the filter screen 2, so that the impurities attached to the filter screen 2 are flushed out into the seawater. The filter screen 2 is arranged at the end of the water inlet pipe 1, and the arc filter screen 2 and the recoil structure are used to smoothly guide the impurities into the seawater, thereby reducing the occurrence of the filtered solids being retained in the pipe.
