Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine water technology, specifically a marine freshwater pressurization system. Background Technology
[0002] Many ships built nowadays are equipped with water heaters, but the usual method is to use an electric freshwater pump to send freshwater from the freshwater tank to a freshwater tank installed on the top deck, and then rely on the pressure difference to supply freshwater to each water point. This results in very low water pressure at each water point, especially at the outlet of the water heater installed in the upper deck bathroom, where the water flow is even lower, and the water heater may even fail to ignite. In order to meet the needs of use, a shipboard freshwater pressurization system is needed.
[0003] Existing freshwater pressurization systems suffer from low water pressure at various water points and high operating costs. Furthermore, the sealing performance of these systems during assembly needs improvement, reducing the sealing effect and compromising stability. Additionally, existing systems typically lack leak detection capabilities, hindering timely inspection and maintenance of the flange connections between the first and second outlet pipes. This lack of protection at the flange connections also allows external impurities to enter the system. Utility Model Content

[0006] Preferably, a holding tank is mounted on the surface of the top of the base. An electric freshwater pump is installed inside the holding tank. The input end of the electric freshwater pump is electrically connected to the output end of the controller. An inlet pipe is installed at the output end of the electric freshwater pump. One end of the inlet pipe passes through the holding tank and the freshwater tank sequentially, extending into the interior of the freshwater tank. A pipe body is installed at the input end of the electric freshwater pump. One end of the pipe body passes through the holding tank and extends to the outside of the holding tank. A mounting tube is provided on the surface of the pipe body, with one end extending into the interior of the pipe body. The surface of the mounting tube is secured by screws. The water tank is threaded and fastened to the surface of the pipe body. A first liquid level sensor and a second liquid level sensor are installed on the inner wall of the freshwater tank. The first liquid level sensor is located above the second liquid level sensor. The output terminals of the first and second liquid level sensors are electrically connected to the input terminal of the controller, respectively. The input terminal of the self-pressurized freshwater pump is electrically connected to the output terminal of the controller. One end of the suction pipe passes through the fixed box and extends to the outside of the fixed box. One end of the inlet pipe passes through the freshwater tank and extends into the interior of the freshwater tank. The interiors of the inlet pipe and the suction pipe are connected.
[0007] Preferably, the leakage detection mechanism consists of a first protective cover, a second protective cover, a fixing block, a mounting stud, a support base, and a leakage sensor. A support base is installed on the surface at the top of the base, a first protective cover is installed on the surface at the top of the support base, and a second protective cover is installed on the surface at the top of the first protective cover. The surfaces of the second protective cover and the first protective cover rotate and cooperate with each other. The second protective cover and the first protective cover are respectively located at the flange connection of the first water outlet pipe and the second water outlet pipe.
[0008] Preferably, the surface of the second protective cover is threaded with mounting studs, one end of which penetrates the second protective cover and is threadedly fastened to the surface of the first protective cover. The inner wall of the second protective cover is equipped with fixing blocks, which engage with the inner wall of the first protective cover. The inner wall of the first protective cover is equipped with a water leakage sensor by screws, and the output end of the water leakage sensor is electrically connected to the input end of the controller.
[0009] Preferably, the sealing assembly mechanism consists of a silicone pad, a first rubber pad, a second rubber pad, and a sealing pad. The inner walls of both the water suction pipe and the water inlet pipe are equipped with the first rubber pad, and the surface of the first rubber pad is equipped with the second rubber pad.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the ship freshwater pressurization system not only greatly improves the sealing effect during assembly when the pressurization system is in use, but also ensures the stability of the pressurization system during assembly and use.

[0012] 1. By setting up a sealing assembly mechanism, the surface of the sealing gasket moves to contact the inner wall of the water inlet pipe. Under the action of the sealing gasket, the sealing performance between the water suction pipe and the water inlet pipe during assembly is improved. When the water suction pipe moves into the interior of the water inlet pipe, the silicone gasket moves to contact the surface of the water suction pipe under the action of the first rubber gasket and the second rubber gasket. Under the combined action of the silicone gasket, the first rubber gasket and the second rubber gasket, the sealing performance between the water suction pipe and the water inlet pipe during assembly is further improved, making it less likely for water to leak at the connection between the water suction pipe and the water inlet pipe. This realizes the function of sealing assembly of the pressurization system, thereby greatly improving the sealing effect during assembly of the pressurization system and ensuring the stability of the pressurization system during assembly and use.
[0013] 2. By incorporating a leakage detection mechanism, the flanges of the first and second water outlet pipes are located inside the first and second protective covers. Supported by a support base, the bottom of the first protective cover is secured. The second protective cover automatically engages with the fixing block on the inner wall of the first protective cover. The user then tightens the mounting studs on the surface of the second protective cover. Under the action of the leakage sensor, leaking water can be detected promptly, and a signal is sent to the controller. Upon receiving the signal, the controller automatically sends a signal to alert the operator that a leak has occurred at the flange connection between the first and second water outlet pipes. This achieves the function of leak detection in the pressurization system, enabling timely detection of leaks at the flange connection during safe use. This allows for timely repair and maintenance, and provides additional safety protection at the flange connection between the first and second water outlet pipes, preventing external impurities from entering the pipeline system.

[0021] The structure of the ship freshwater pressurization system provided by this utility model is as follows: Figure 1 , Figure 2 and Figure 3As shown, the system includes a freshwater tank 1, a base 102 mounted on the bottom surface of the freshwater tank 1, a controller 101 (model LA series) mounted on the surface of the freshwater tank 1, and a container 106 mounted on the top surface of the base 102.

An inlet pipe 107 is installed at the output terminal of the electric freshwater pump 105, with one end of the inlet pipe 107 passing through both the container 106 and the freshwater tank. 1. Extending into the interior of the freshwater tank 1, the input end of the electric freshwater pump 105 is equipped with a pipe body 104. One end of the pipe body 104 passes through the container 106 and extends to the outside of the container 106. An installation tube 103 is provided on the surface of the pipe body 104, one end of which extends into the interior of the pipe body 104. The surface of the installation tube 103 is fastened to the surface of the pipe body 104 by screws. A first liquid level sensor 108 is installed on the inner wall of the freshwater tank 1. The first liquid level sensor 108 can be of the WE series. A second liquid level sensor 113 is installed on the inner wall of the freshwater tank 1. Model 3 can be from the WE series. The first liquid level sensor 108 is located above the second liquid level sensor 113. The output terminals of the first liquid level sensor 108 and the second liquid level sensor 113 are electrically connected to the input terminal of the controller 101, respectively. A fixing box 109 is installed on the surface of the top position of the base 102. A self-pressurized freshwater pump 110 is installed inside the fixing box 109. The model of the self-pressurized freshwater pump 110 can be from the ZX series. The input terminal of the self-pressurized freshwater pump 110 is electrically connected to the output terminal of the controller 101. A suction pipe 111 is installed at the input terminal of the self-pressurized freshwater pump 110. One end of the water inlet pipe 111 passes through the fixed box 109 and extends to the outside of the fixed box 109. The surface of the suction pipe 111 is fitted with a water inlet pipe 112 by screws. One end of the water inlet pipe 112 passes through the freshwater tank 1 and extends into the freshwater tank 1. The water inlet pipe 112 is connected to the inside of the suction pipe 111. The output end of the self-pressurized freshwater pump 110 is fitted with a second outlet pipe 115. One end of the second outlet pipe 115 passes through the fixed box 109 and extends to the outside of the fixed box 109. The surface of the second outlet pipe 115 is fitted with a first outlet pipe 114 by screws. The first outlet pipe 114 is connected to the inside of the second outlet pipe 115.
[0022] Furthermore, such as Figure 2 and Figure 5As shown, the inner walls of the suction pipe 111 and the water inlet pipe 112 are provided with a sealing assembly mechanism 3. The sealing assembly mechanism 3 consists of a silicone pad 31, a first rubber pad 32, a second rubber pad 33, and a sealing pad 34. The inner walls of both the suction pipe 111 and the water inlet pipe 112 are equipped with a first rubber pad 32. The surface of the first rubber pad 32 is equipped with a second rubber pad 33. The surface of the second rubber pad 33 away from the first rubber pad 32 is equipped with a silicone pad 31. The surface of the silicone pad 31 is in contact with the inner wall of the suction pipe 111. The inner walls of both the suction pipe 111 and the water inlet pipe 112 are equipped with a sealing pad 34. The surface of the sealing pad 34 is in contact with the inner wall of the water inlet pipe 112.
[0023] During implementation, when assembling the suction pipe 111 and the water inlet pipe 112, the surface of the sealing gasket 34 moves to contact the inner wall of the water inlet pipe 112. Under the action of the sealing gasket 34, the sealing performance between the suction pipe 111 and the water inlet pipe 112 is improved. When the suction pipe 111 moves into the interior of the water inlet pipe 112, the silicone gasket 31 moves to contact the surface of the suction pipe 111 under the action of the first rubber gasket 32 and the second rubber gasket 33. Under the combined action of the silicone gasket 31, the first rubber gasket 32 and the second rubber gasket 33, the sealing performance during the assembly of the suction pipe 111 and the water inlet pipe 112 is further improved, making it less likely for water to leak at the connection between the suction pipe 111 and the water inlet pipe 112, thus realizing the function of sealing assembly of the pressurization system.
[0024] Furthermore, such as Figure 2 and Figure 4 As shown, a leakage detection mechanism 2 is provided on the surface of the first water outlet pipe 114 and the second water outlet pipe 115. The leakage detection mechanism 2 consists of a first protective cover 21, a second protective cover 22, a fixing block 23, a mounting stud 24, a support base 25, and a leakage sensor 26. A support base 25 is installed on the surface of the top position of the base 102. The first protective cover 21 is installed on the surface of the top position of the support base 25. The second protective cover 22 is provided on the surface of the top position of the first protective cover 21. The surfaces of the second protective cover 22 and the first protective cover 21 rotate and cooperate with each other. The second protective cover 22 and the first protective cover 21 are separated. Located at the flange connection of the first water outlet pipe 114 and the second water outlet pipe 115, the surface of the second protective cover 22 is threaded with mounting studs 24. One end of the mounting stud 24 passes through the second protective cover 22 and is threadedly fastened to the surface of the first protective cover 21. The inner wall of the second protective cover 22 is equipped with fixing blocks 23, which are engaged with the inner wall of the first protective cover 21. The inner wall of the first protective cover 21 is equipped with a leakage sensor 26 by screws. The leakage sensor 26 can be of the ZH series. The output end of the leakage sensor 26 is electrically connected to the input end of the controller 101.
[0025] During implementation, the flanges of the first water outlet pipe 114 and the second water outlet pipe 115 are located inside the first protective cover 21 and the second protective cover 22. The support base 25 supports the bottom of the first protective cover 21. Then, the user rotates the second protective cover 22 on the surface of the first protective cover 21, causing the second protective cover 22 to automatically engage with the fixing block 23 against the inner wall of the first protective cover 21. The fixing block 23 positions the first protective cover 21 and the second protective cover 22. The user then tightens the mounting studs 2 on the surface of the second protective cover 22. 4. With the help of the mounting studs 24, the second protective cover 22 and the first protective cover 21 are installed together. When water leakage occurs at the flange connection of the first water outlet pipe 114 and the second water outlet pipe 115, the leakage sensor 26 can detect the leaking water in time and send the signal to the controller 101. After receiving the signal, the controller 101 automatically sends a signal to remind the staff that there is a water leakage at the flange connection of the first water outlet pipe 114 and the second water outlet pipe 115, so that timely inspection and maintenance can be carried out to realize the function of water leakage monitoring of the pressurization system.
[0026] Working principle: In use, first place the freshwater tank 1 in the designated location. The user installs the mounting tube 103 on the surface of the tube body 104 using screws, and then assembles the suction tube 111 and the inlet tube 112 together using screws, allowing one end of the inlet tube 112 to move into the freshwater tank 1. Then, the first outlet tube 114 and the second outlet tube 115 are installed together using screws. When the water level in the freshwater tank 1 is lower than the surface of the second level sensor 113, the second level sensor 113 sends a signal to the controller 101. After receiving the signal from the second level sensor 113, the controller 101 starts the electric freshwater pump 105 inside the container 106, injecting freshwater into the freshwater tank 1 through the mounting tube 103, tube body 104, and inlet tube 107 until the freshwater reaches the surface of the first level sensor 108. The first level sensor 108 then detects the water level and... The signal is sent to the controller 101. After receiving the signal from the first liquid level sensor 108, the controller 101 controls the electric freshwater pump 105 to stop working and stop filling the freshwater tank 1 with water. When each water point is turned on, the self-pressurized freshwater pump 110 draws freshwater out of the freshwater tank 1 through the suction pipe 111 and the inlet pipe 112 and delivers the freshwater to the second outlet pipe 115 and the first outlet pipe 114. When each water point is turned on, pressurized water is provided through the second outlet pipe 115 and the first outlet pipe 114 to increase the pressure at each water point. This achieves the purpose of saving costs, facilitating modification, and shortening the modification cycle. Compared with freshwater pressure tanks, this increases the construction cost of the ship. It is especially difficult and costly to install the above equipment on some modified ships. The ZX series can be selected for the self-pressurized freshwater pump 110.
[0027] Subsequently, during the assembly of the suction pipe 111 and the water inlet pipe 112, the surface of the sealing gasket 34 moves to contact the inner wall of the water inlet pipe 112. Under the action of the sealing gasket 34, the sealing performance between the suction pipe 111 and the water inlet pipe 112 during assembly is improved. When the suction pipe 111 moves into the interior of the water inlet pipe 112, the silicone gasket 31 moves to contact the surface of the suction pipe 111 under the action of the first rubber gasket 32 and the second rubber gasket 33. Under the combined action of the silicone gasket 31, the first rubber gasket 32 and the second rubber gasket 33, the sealing performance during the assembly of the suction pipe 111 and the water inlet pipe 112 is further improved, making it less likely for water to leak at the connection between the suction pipe 111 and the water inlet pipe 112. This achieves the function of sealing the pressurization system during assembly, thereby greatly improving the sealing effect during the use of the pressurization system and ensuring the stability of the pressurization system during assembly and use.
[0028] Subsequently, the flanges of the first water outlet pipe 114 and the second water outlet pipe 115 are located inside the first protective cover 21 and the second protective cover 22. Supported by the support base 25, the bottom of the first protective cover 21 is supported. Then, the user rotates the second protective cover 22 on the surface of the first protective cover 21, causing the second protective cover 22 to automatically engage with the fixing block 23 against the inner wall of the first protective cover 21. The fixing block 23 positions the first protective cover 21 and the second protective cover 22. The user then tightens the mounting studs 24 on the surface of the second protective cover 22, securing the second protective cover 22 and the first protective cover 21 together. When leakage occurs at the flange connection between the first water outlet pipe 114 and the second water outlet pipe 115, [the system will respond accordingly]. Sensor 26 can detect leaking water in a timely manner and send a signal to controller 101. After receiving the signal, controller 101 automatically sends a signal to prompt the staff that there is a leak at the flange connection of the first water outlet pipe 114 and the second water outlet pipe 115, so that timely inspection and maintenance can be carried out to realize the function of water leakage monitoring of the pressurization system. This allows for timely detection of whether there is a leak at the flange connection of the first water outlet pipe 114 and the second water outlet pipe 115 during safe use, enabling timely inspection and maintenance. At the same time, it can provide additional safety protection for the flange connection of the first water outlet pipe 114 and the second water outlet pipe 115, preventing external impurities from entering the pipeline system, and ultimately completing the use of the freshwater pressurization system.
