[0025] During implementation, under the combined action of the sealing airbag 231 and the sealing spring 232 inside the sealing frame 22, the sealing gasket 21 is driven to move, causing the sealing gasket 21 to slide inside the sealing groove 233. Under the action of the sealing groove 233, the sealing gasket 21 is guided. At this time, the sealing airbag 231 and the sealing spring 232 drive the sealing gasket 21 to move into contact with the inner walls of the fresh water tank body 104 and the seawater inlet pipe 105. Under the combined action of the sealing gasket 21 and the sealing frame 22, sealing and leakage prevention treatment is carried out between the fresh water tank body 104, the fresh water pump 1, the seawater pump 101, and the seawater inlet pipe 105, making the sealing performance between the fresh water tank body 104 and the fresh water pump 1, and between the seawater pump 101 and the seawater inlet pipe 105 higher, so as to achieve the function of sealing and leakage prevention of the switching device.
[0026] Furthermore, as Figure 2 and Figure 4 shown, convenient assembly mechanisms 3 are provided on the surfaces of the first outlet pipe 106 and the pipe line 108, and the second outlet pipe 107 and the pipe line 108. The inside of the convenient assembly mechanism 3 includes an installation block 31, an installation groove 32, and a convenient assembly part 33. The convenient assembly part 33 is provided on the surfaces of the first outlet pipe 106 and the pipe line 108, and the second outlet pipe 107 and the pipe line 108. The convenient assembly part 33 is composed of a guiding groove 331, a guiding block 332, an anti-loosening clamping part 333, and an L-shaped fixing bracket 334. L-shaped fixing brackets 334 are installed on the surfaces on both sides of the pipe line 108. Guiding blocks 332 are installed on the surfaces of the first outlet pipe 106 and the second outlet pipe 107. A guiding groove 331 is formed in the inner wall of the L-shaped fixing bracket 334, and the surfaces of the guiding groove 331 and the guiding block 332 are slidably matched with each other. An anti-loosening clamping part 333 for preventing the first outlet pipe 106 welded to the second outlet pipe 107 from loosening is installed on the surface of the guiding block 332, and the anti-loosening clamping part 333 is clamped and matched with the inner wall of the L-shaped fixing bracket 334. Installation blocks 31 for positioning and installing the first outlet pipe 106 and the second outlet pipe 107 are installed on the inner walls of the pipe line 108. Installation grooves 32 are formed in the inner walls of the first outlet pipe 106 and the second outlet pipe 107, and the surfaces of the installation grooves 32 and the installation blocks 31 are clamped and matched with each other.
[0027] During implementation, the first water outlet pipe 106 and the second water outlet pipe 107 drive the guide block 332 to slide inside the guide groove 331. Under the combined action of the guide groove 331 and the guide block 332, the first water outlet pipe 106 and the second water outlet pipe 107 are guided, so that the guide block 332 drives the anti-loosening card 333 to be stuck into the L-shaped fixing bracket 334. Under the action of the anti-loosening card 333, the first water outlet pipe 106 and the second water outlet pipe 107 are prevented from loosening. When the first water outlet pipe 106 and the second water outlet pipe 107 are installed on the surface of the water pipe line 108, at this time, the installation block 31 is stuck into the installation groove 32. Under the combined action of the installation block 31 and the installation groove 32, the first water outlet pipe 106 and the second water outlet pipe 107 are positioned and installed, so as to realize the function that the switching device facilitates the assembly of the first water outlet pipe 106 and the second water outlet pipe 107.
[0028] Further, as Figure 2 and Figure 5 shown, a filtering and blocking mechanism 4 is arranged inside the seawater inlet pipe 105. The filtering and blocking mechanism 4 includes a first magnet 41, a second magnet 42, a block 43, a fixing block 44, a fixing groove 45 and a blocking net plate 46. A blocking net plate 46 for blocking fish and waterweeds is arranged inside the seawater inlet pipe 105. Fixing blocks 44 are installed on the surfaces on both sides of the blocking net plate 46. Fixing grooves 45 are formed on the inner walls of the seawater inlet pipe 105. The surfaces of the fixing grooves 45 and the fixing blocks 44 are slidably matched with each other. Blocks 43 are installed on the inner walls of the seawater inlet pipe 105. A second magnet 42 is installed on the surface of the block 43. A first magnet 41 is installed on the surface of the blocking net plate 46. The surfaces of the first magnet 41 and the second magnet 42 are magnetically attracted to each other.
[0029] During implementation, the user places the blocking net plate 46 inside the seawater inlet pipe 105, so that the blocking net plate 46 drives the fixing block 44 to slide inside the fixing groove 45. Under the combined action of the fixing block 44 and the fixing groove 45, the blocking net plate 46 is positioned and installed. At this time, the blocking net plate 46 drives the first magnet 41 to move into contact with the surface of the second magnet 42 on the surface of the block 43. Under the magnetic attraction of the second magnet 42 and the first magnet 41, the blocking net plate 46 is installed inside the seawater inlet pipe 105. Under the action of the blocking net plate 46, fish and waterweeds in the seawater are blocked, preventing the waterweeds and fish from entering the inside of the seawater inlet pipe 105, so as to realize the function of the switching device to block fish and waterweeds in the seawater.
[0030] Working principle: When in use, first place the two fresh water pumps 1 at the designated positions. The user places the first outlet pipe 106 and the second outlet pipe 107 on the surface of the water pipe line 108 respectively. The user pushes the first outlet pipe 106 and the second outlet pipe 107, so that the first outlet pipe 106 and the second outlet pipe 107 drive the guide block 332 to slide inside the guide groove 331. Under the combined action of the guide groove 331 and the guide block 332, the first outlet pipe 106 and the second outlet pipe 107 are guided, so that the guide block 332 drives the anti-loosening card 333 to be stuck into the L-shaped fixing bracket 334. Under the action of the anti-loosening card 333, the first outlet pipe 106 and the second outlet pipe 107 are prevented from loosening. When the first outlet pipe 106 and the second outlet pipe 107 are installed on the surface of the water pipe line 108, at this time, the installation block 31 is stuck into the installation groove 32. Under the combined action of the installation block 31 and the installation groove 32, the first outlet pipe 106 and the second outlet pipe 107 are positioned and installed, so as to realize the function that the switching device is convenient for assembling the first outlet pipe 106 and the second outlet pipe 107, so that when the switching device is in use, the first outlet pipe 106 and the second outlet pipe 107 can be stably installed on the surface of the water pipe line 108, which is convenient for the user to operate and makes the overall stability of the switching device higher when in use.
[0031] Subsequently, the user places the blocking net plate 46 inside the seawater inlet pipe 105, so that the blocking net plate 46 drives the fixing block 44 to slide inside the fixing groove 45. Under the combined action of the fixing block 44 and the fixing groove 45, the blocking net plate 46 is positioned and installed. At this time, the blocking net plate 46 drives the first magnet 41 to move to contact the surface of the second magnet 42 on the surface of the block 43. Under the magnetic attraction of the second magnet 42 and the first magnet 41, the blocking net plate 46 is installed inside the seawater inlet pipe 105. Under the action of the blocking net plate 46, fish and water plants in the seawater are blocked, and water plants and fish are prevented from entering the inside of the seawater inlet pipe 105, so as to realize the function of the switching device for blocking fish and water plants in the seawater, so that when the switching device is in use, fish and water plants can be prevented from entering the inside of the seawater pump 101 through the seawater inlet pipe 105, affecting the flushing of the deck and the joint, and making the switching device more practical when in use.
[0032] Subsequently, when using fresh water, power is supplied to the fresh water pump 1 while the two ball valves 103 on the left side are opened, and then the two ball valves 103 on the right side are closed. In this way, the entire water pipe line 108 uses fresh water. After the fresh water enters the interior of the water pipe line 108, the fresh water is then made to enter the indoor toilet through the first water outlet pipe 106 or reach the deck flushing joint through the second water outlet pipe 107. When seawater needs to be used, the two ball valves 103 on the left side are closed and the two ball valves 103 on the right side are opened, so that the entire water pipe line 108 uses seawater. Then, the seawater is made to enter the indoor toilet through the first water outlet pipe 106 or reach the deck flushing joint through the second water outlet pipe 107. This can save the consumption of fresh water and extend the endurance time of fresh water. The operation is made simpler through the conversion of the ball valves 103. Under the action of the check valve 102, the risk of seawater entering the fresh water tank due to all four ball valves 103 being opened simultaneously can be prevented.
[0033] Subsequently, the user places the fresh water tank body 104 on the surface of the fresh water pump 1 and places the seawater inlet pipe 105 on the surface of the seawater pump 101, so that one end of the fresh water tank body 104 moves into the interior of the fresh water pump 1 and one end of the seawater inlet pipe 105 moves into the interior of the seawater pump 101. The user tightens the screws to install the fresh water tank body 104 on the surface of the fresh water pump 1 and install the seawater inlet pipe 105 on the surface of the seawater pump 101. Under the combined action of the sealing airbag 231 and the sealing spring 232 inside the sealing frame 22, the sealing gasket 21 is driven to move, so that the sealing gasket 21 slides inside the sealing groove 233. Under the action of the sealing groove 233, the sealing gasket 21 is guided. At this time, the sealing airbag 231 and the sealing spring 232 drive the sealing gasket 21 to move into contact with the inner walls of the fresh water tank body 104 and the seawater inlet pipe 105. Under the combined action of the sealing gasket 21 and the sealing frame 22, a sealing and leak-proof treatment is carried out between the fresh water tank body 104 and the fresh water pump 1, and between the seawater pump 101 and the seawater inlet pipe 105, so that the sealing performance between the fresh water tank body 104 and the fresh water pump 1, and between the seawater pump 101 and the seawater inlet pipe 105 is higher, to achieve the function of the switching device being sealed and leak-proof. Thus, when the switching device is used, leakage between the fresh water pump 1 and the fresh water tank body 104, and between the seawater pump 101 and the seawater inlet pipe 105 can be avoided, the sealing performance of the switching device during use is higher, and no waste of fresh water resources will occur during use. Finally, the use of the switching device is completed.
