DETAILED DESCRIPTION
[0030] The embodiments of the present application will be described in detail below with reference to the accompanying drawings, but the present application can be implemented in various different ways as defined and covered by the following.
[0031] The embodiments of the present application are used to provide a shipboard aero-engine cleaning device for directly cleaning the engine or supplying water to the engine with a self-provided cleaning device.
[0032] Figures 1-2 The structural schematic diagram of the cleaning device in the embodiments of the present application is shown. Referring to Figures 1-2 , the cleaning device comprises a water tank 1, a box 2, a pipe coiler assembly 3, an output assembly, and a control assembly 5.
[0033] The box 2 has a sealed chamber 27, and the output assembly, the control assembly 5, and the pipe coiler assembly 3 are all installed in the sealed chamber 27, so that the output assembly, the control assembly 5, and the pipe coiler assembly 3 are isolated from the external environment, the corrosion of the output assembly, the control assembly 5, and the pipe coiler assembly 3 by the high-salt-mist environment at sea is reduced, the aging of the devices is effectively alleviated, the service life of the overall device in the high-salt-mist environment at sea is increased, and at the same time, the appearance of the overall device is more simple because the output assembly, the control assembly 5, and the pipe coiler assembly 3 are all arranged in the sealed chamber 27, the shape and size of the sealed chamber 27 are designed according to the shape and volume of the output assembly, the control assembly 5, and the pipe coiler assembly 3, and thus the volume of the box 2 is reduced.
[0034] The water tank 1, the output assembly, and the pipe coiler assembly 3 are connected in sequence by pipelines to form a passage, the water tank 1 is used to store water, as shown in Figure 4 , the water tank 1 is provided with a water outlet 13 on the side in contact with the box 2, the water outlet 13 is connected in communication with the first end of the output assembly by a pipeline, and the second end of the output assembly is connected in communication with the pipe coiler assembly 3 by a pipeline, and the output assembly is used to pressurize the water in the water tank 1 and send it to the pipe coiler assembly 3.
[0035] As shown in Figure 2As shown, the hose reel assembly 3 comprises a hose reel 31 and a water hose 32, the hose reel 31 is provided with a rotary joint, the first end of the rotary joint is connected with the second end of the output assembly through a pipeline, and the second end is connected with the first end of the water hose 32. The water output by the output assembly enters the water hose 32 through the rotary joint and is finally sent out by the water hose 32. The hose reel 31 is used to wind the water hose 32 on its surface. When the water hose 32 is needed, it can be pulled out of the hose reel 31. When not in use, it can be wound back by the hose reel 31. The hose reel 31 is a conventional technical means in the art, which will not be described in detail here. It can only realize automatic locking when the water hose 32 is pulled out, and automatic winding of the water hose 32 after unlocking.
[0036] Wherein, the water tank 1 is fixedly connected or detachably connected with the box 2, and the present application does not limit this, as long as the water tank 1 can continuously output water flow to the output assembly, Figure 1 An exemplary arrangement of the water tank 1 is shown, referring to Figure 1 The water tank 1 is fixedly arranged on one side of the box 2. A water inlet 11 is formed in the top of the water tank 1, which is funnel-shaped to facilitate water filling. A water outlet is arranged at the bottom of the water tank 1. When stored, the water in the water tank 1 can be completely discharged to the outside through the water outlet.
[0037] Wherein, the output assembly is a water pump 41, which pressurizes and sends out the water in the water tank 1, as Figure 3 shown, in some embodiments, the water pump 41 adopts a micro diaphragm pump, which has small volume and weight, thereby reducing the volume of the box 2 and the weight of the overall device.
[0038] As Figure 3 shown, in some embodiments, the first end of the water pump 41 is in communication with the water tank 1, and the second end of the water pump 41 is sequentially connected with a heater 42 and a safety valve 43. The heater 42 is used to heat the water sent out by the water pump 41 to meet the temperature requirements of different engines for cleaning water. The safety valve 43 is used to relieve pressure when the water pressure in the pipeline is too high to ensure the safety of the overall device, and Figure 3 also shows an exemplary installation mode of the water pump 41, the heater 42 and the safety valve 43. In this exemplary installation mode, the water pump 41, the heater 42 and the safety valve 43 are reasonably arranged and compactly structured, which is conducive to reducing the volume of the overall device.
[0039] Figure 2 An exemplary installation mode of the control assembly 5 is shown. The control assembly 5 is used to control the water pump 41, the heater 42 and various sensors in the device to control the flow and temperature of the output water flow, adapt to different environments and different types of engines, Figure 7An exemplary mounting mode of the control assembly 5 is shown, in which a convex plate 51 is fixedly mounted on the inner wall of the sealing chamber 27, and a protection chamber is formed between the convex plate 51 and the sealing chamber 27. The control assembly 5 is mounted in the protection chamber formed by the convex plate 51 and the inner wall of the sealing chamber 27, so as to isolate the control assembly 5. Since the control assembly 5 mainly consists of a PLC programmable controller, a relay, a potentiometer, a power module, a temperature transmitter and the like, waterproof design is required to prevent water from flowing in and causing short circuit.
[0040] As shown in Figure 6 , in some embodiments, a battery 71 and a charging interface 72 are mounted in the sealing chamber 27. The battery 71 is used to provide the required power for the overall device. The battery 71 is mounted at the bottom end of the sealing chamber 27, so as to lower the center of gravity of the overall device and ensure the stability of the overall device.
[0041] As shown in Figures 8-9 , one side of the box body 2 is provided with a through hole 21 communicating with the sealing chamber 27. A sealing baffle 61 is mounted in the through hole 21. A circular hole 62 is formed on the surface of the sealing baffle 61. The water pipe 32 in the pipe coiler assembly 3 extends out of the box body 2 through the circular hole 62. The sealing baffle 61 is made of elastic material and the diameter of the circular hole 62 is smaller than the outer diameter of the water pipe 32. Therefore, the sealing baffle 61 can be partially clamped on the surface of the water pipe 32 through the circular hole 62, so as to partially close the through hole 21 and completely seal the sealing chamber 27, thereby ensuring the sealing effect of the sealing chamber 27. At the same time, when using the device, the water pipe 32 needs to be pulled out of the box body 2 by a certain length. During the cleaning process of the engine, water mist or water droplets will scatter to the surface of the part of the water pipe 32 extending out of the box body 2. During the subsequent process of pulling the water pipe 32 back into the box body 2, the sealing baffle 61 clamped on the surface of the water pipe 32 can also intercept the water stains remaining on the surface of the water pipe 32, so as to prevent the water stains from entering the sealing chamber 27 together with the water pipe 32. In this way, the sealing effect of the sealing chamber 27 is ensured while the water pipe 32 can normally enter and exit the sealing chamber 27. At the same time, the water pipe 32 can also prevent water from entering the sealing chamber 27, so as to ensure the sealing effect of the sealing chamber 27 and protect the components in the sealing chamber 27.
[0042] In addition, as shown in Figures 8-9As shown, in some embodiments, the part of the water pipe 32 located in the sealed chamber 27 is sleeved with an extrusion ring 63, and the extrusion ring 63 has a certain friction with the water pipe 32, so that the extrusion ring 63 can move synchronously with the water pipe 32. The end of the extrusion ring 63 close to the sealing baffle 61 is formed with a wedge-shaped section for inserting between the sealing baffle 61 and the water pipe 32. During the pulling out of the water pipe 32, the extrusion ring 63 moves with the water pipe 32 under the friction of the water pipe 32. When the wedge-shaped section is inserted between the sealing baffle 61 and the water pipe 32, the friction of the water pipe 32 on the extrusion ring 63 and the resistance of the sealing baffle 61 to the extrusion ring 63 are balanced, so that the extrusion ring 63 reaches the first limit position. At this time, the wedge-shaped section of the extrusion ring 63 separates the inner wall surface of the circular hole 62 in the sealing baffle 61 from the water pipe 32. During the subsequent pulling out of the water pipe 32, the extrusion ring 63 and the sealing baffle 61 remain relatively static, so that the sealing baffle 61 is no longer subjected to friction, reducing the wear between the water pipe 32 and the sealing baffle 61 during the pulling out of the water pipe 32 from the sealed chamber 27, and increasing the service life of the sealing baffle 61. When the pipe winder 31 pulls the water pipe 32 from the outside of the box body 2 into the sealed chamber 27 in the box body 2, the extrusion ring 63 moves away from the sealing baffle 61 along with the water pipe 32, and is out of contact with the sealing baffle 61, so that the sealing baffle 61 returns to the initial state, and the inner wall surface of the circular hole 62 is again closely attached to the surface of the water pipe 32, ensuring the cleaning effect of the water pipe 32 on the water stain during the pulling back and the sealing effect during the subsequent storage. Without affecting the sealing effect of the sealing baffle 61 on the sealed chamber 27, the wear of the sealing baffle 61 during use is reduced, and the service life of the sealing baffle 61 is effectively increased.
[0043] Figure 9 An example of the extrusion ring is shown. In this example, the extrusion ring 63 is a circular truncated cone. The diameter of the side of the extrusion ring 63 close to the through hole 21 is smaller than the diameter of the side of the extrusion ring 63 away from the through hole 21. When the sealing baffle 61 is extruded by the extrusion ring 63, the extrusion ring 63 will directly expand the circular hole 62 from the inner cavity of the circular hole 62 through its inclined surface, so that the inner wall surface of the circular hole 62 is no longer in contact with the water pipe 32, eliminating the friction between the sealing baffle 61 and the water pipe 32, thereby achieving the effect of protecting the sealing baffle 61. The smaller end of the extrusion ring 63 faces the sealing baffle 61, so that the extrusion ring 63 can more easily separate the inner wall surface of the circular hole 62 from the surface of the water pipe 32, achieving the effect of reducing wear.
[0044] As shown, in some embodiments, the side of the extrusion ring 63 in contact with the water pipe 32 is provided with a hollow groove, reducing the contact area between the extrusion ring 63 and the water pipe 32. Under the premise of ensuring that the extrusion ring 63 can move synchronously with the water pipe 32, the friction between the extrusion ring 63 and the water pipe 32 is reduced as much as possible, reducing the wear on the surface of the water pipe 32.
[0045] In some examples, a circular hole 62 is formed at the bottom end of the sealing baffle 61, so that the water pipe 32 can contact the bottom end of the through hole 21 while passing through the circular hole 62, and the water pipe 32 is supported by the through hole 21 to prevent the deformation of the sealing baffle 61 caused by the gravity of the water pipe 32, thereby ensuring the sealing effect of the sealing baffle 61 on the through hole 21.
[0046] As shown in Figure 8 some examples, a support frame 22 is installed in the sealing chamber 27 or outside the box 2, and the support frame 22 is used to maintain the height of the water pipe 32 to prevent the weight of the water pipe 32 from acting on the sealing baffle 61.
[0047] Figure 8 An example installation mode of the support frame 22 is shown, and in this example, the support frame 22 is installed in the sealing chamber 27, and the support frame 22 is composed of a plurality of support rollers arranged circumferentially. The position of the water pipe 32 on the first plane is fixed by the support rollers to prevent displacement of the water pipe 32 on the first plane, which causes the sealing baffle 61 to deform and cause sealing failure. The first plane is perpendicular to the axis of the circular hole 62.
[0048] Figure 9 An example installation mode of the extrusion ring 63 is shown. The extrusion ring 63 is located between the support frame 22 and the wall surface of the sealing chamber 27, and a limiting surface for blocking the extrusion ring 63 is formed on the support frame 22. During the retraction of the water pipe 32, the extrusion ring 63 moves with the water pipe 32 under the friction force of the water pipe 32. When the extrusion ring 63 contacts the limiting surface, the friction force of the water pipe 32 on the extrusion ring 63 and the resistance of the support frame 22 to the extrusion ring 63 are balanced, so that the extrusion ring 63 reaches the second limit position. When the extrusion ring 63 reaches the second limit position, it will be out of contact with the sealing baffle 61, thereby ensuring that the sealing baffle 61 and the water pipe 32 form a seal.
[0049] Referring to Figure 1 In some embodiments, the surface of the box 2 is provided with an operation panel 8. The buttons such as switches, power displays, power sources, and flow displays on the operation panel 8 are assembled from the inside of the box 2, and then covered by a protective plate to isolate the environment outside. The protective plate is sealed and fixed to the box 2 by glue to avoid direct contact between the devices on the operation panel 8 and the environment, thereby preventing aging.
[0050] Referring to Figure 5The bottom and the top of the box 2 are respectively provided with a roller 24 and a handle 23, the roller 24 is arranged on one side of the bottom of the box 2, so that the whole device can be moved very easily by the handle 23 in use, and in some embodiments, the bottom of the box 2 can be provided with a rubber pad 25, and the height of the rubber pad 25 to the bottom surface of the box 2 is not less than the height of the bottom end of the roller 24 to the bottom surface of the box 2, when the box 2 is kept in an upright state, the rubber pad 25 at the bottom end of the box 2 can be in complete contact with the ground, and the stability of the box 2 is kept by the friction of the rubber pad 25, and when the box 2 needs to be moved, the box 2 only needs to be inclined to make the rubber pad 25 out of contact with the ground, at this time the roller 24 touches the ground, and the box 2 can be moved easily.
[0051] Reference Figure 1 In some embodiments, the side of the box 2 is provided with a tethering device 26, because the ship will sway during sailing on the sea, in order to ensure the stability of the device during storage, the tethering device 26 is arranged on the side of the box 2, the tethering device 26 can be connected with the fixed member on the ship, so as to increase the stability of the device during the ship swaying.
[0052] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and the present application can have various changes and variations for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
