Description

Technical Field

[0001] The utility model relates to the field of ballast water system equipment, in particular to a ballast water system water level monitoring device. Background Art

[0002] The ballast water system is a system used for ships and offshore platforms, mainly composed of ballast water pumps, ballast water pipelines, ballast tanks and related valves; the system uses the power of ballast water to reduce the impact of external forces such as wind and waves, rudders, thrust, etc. encountered by ships at sea, thereby improving the stability of the hull and navigation performance.

[0003] When in use, it is necessary to monitor the water level height inside the ballast tank to ensure that the user is clearly aware of the specific water level value, thereby ensuring the safe and normal operation of the device. However, due to the poor stability of the hull, when monitoring the water level, the water source inside the ballast tank fluctuates, causing the water level monitoring data to fluctuate, resulting in inaccurate water level monitoring data. Therefore, a device is urgently needed to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a ballast water system water level monitoring device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ballast water system water level monitoring device, including a ballast tank, a fixed pipe is fixedly installed on one side of the ballast tank, the bottom end of the ballast tank is in a connected state with the inside of the fixed pipe, a floating block is slidably installed inside the fixed pipe, a fixed rod is fixedly installed on the top of the floating block, a fixed block is fixedly installed on the top of the fixed rod, a vertical plate is fixedly installed on one side of the fixed pipe, a warning light is fixedly installed on one side of the vertical plate, a plurality of trigger switches are fixedly installed on one side of the vertical plate, and a fixed block is fixed on one side of the fixed block. An elastic sheet is provided, and a display mechanism is provided on the top of the vertical plate. When in use, the principle of communicating vessels is utilized so that the liquid level inside the fixed pipe is the same as the liquid level inside the ballast tank, and relative to the ballast tank, the area inside the fixed pipe is small, so that the liquid level inside the fixed pipe is less affected by the hull fluctuations, and the floating block floats on the upper end of the liquid level inside the fixed pipe. As the liquid level changes, the floating block drives the fixed rod to move up and down, so that the elastic sheet moves along one side of the vertical plate until it contacts the corresponding trigger switch, so that the corresponding warning light is lit, thereby determining the liquid level inside the ballast tank and improving the accuracy of water level monitoring.

[0006] Preferably, the display mechanism includes a display screen and a control box, the display screen is fixed at the top position of the vertical plate, the control box is fixed at one side of the display screen, and the control box is electrically connected to the trigger switch. When the trigger switch on one side is contacted and triggered, the electrical signal is transmitted to the inside of the control box, and the specific water level value is displayed on the display screen, which makes it more convenient to observe the water level value.

[0007] Preferably, a plurality of fixed rings are evenly and fixedly arranged inside the fixed tube. When in use, the water source flowing into the fixed tube first passes through the fixed ring. When the water source passes through the fixed tube too quickly, it is easy to cause a large liquid level difference inside the fixed tube. At this time, the water source will impact the fixed ring and reduce the water source flow rate inside the fixed tube, thereby further ensuring the stability of the liquid level inside the fixed tube.

[0008] Preferably, the top end of the fixing rod movably extends to a position outside the top end of the fixing tube.

[0009] Preferably, the warning light is an LED light, and a scale line is provided on a side of the vertical plate close to the warning light.

[0011] Preferably, one side of the elastic sheet is in close contact with the vertical plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model utilizes the communicating vessel principle when in use, so that the liquid level inside the fixed pipe is the same as the liquid level inside the ballast tank, and the area inside the fixed pipe is small relative to the ballast tank, so that the liquid level inside the fixed pipe is less affected by the hull fluctuations, and the floating block floats on the upper end of the liquid level inside the fixed pipe. As the liquid level changes, the floating block drives the fixed rod to move up and down, so that the elastic sheet moves along one side of the vertical plate until it contacts the corresponding trigger switch, so that the corresponding warning light is lit, so as to determine the liquid level inside the ballast tank and improve the accuracy of water level monitoring;

[0014] 2. When the utility model is in use, the water flowing into the fixed pipe first passes through the fixed ring. When the water passes through the fixed pipe too quickly, it is easy to cause a large difference in the liquid level inside the fixed pipe. At this time, the water will impact the fixed ring and reduce the flow rate of the water inside the fixed pipe, thereby further ensuring the stability of the liquid level inside the fixed pipe.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a ballast water system water level monitoring device, including a ballast tank 1, a fixed pipe 2 is embedded and fixed on one side of the ballast tank 1, the bottom end of the ballast tank 1 is in a connected state with the inside of the fixed pipe 2, a floating block 7 is slidably arranged inside the fixed pipe 2, a fixed rod 8 is embedded and fixed on the top of the floating block 7, the top of the fixed rod 8 is movably extended to the outside position of the top of the fixed pipe 2, a fixed block 12 is welded and fixed on the top of the fixed rod 8, a vertical plate 3 is welded and fixed on one side of the fixed pipe 2, a warning light 10 is embedded and fixed on one side of the vertical plate 3, the warning light 10 is an LED light, a scale line is provided on one side of the vertical plate 3 near the warning light 10, a plurality of trigger switches 9 are embedded and fixed on one side of the vertical plate 3, the trigger switches 9 are electrically connected to the warning light 10, and the number of the trigger switches 9 is equal to the number of the warning lights 10 The two ballast tanks 1 are the same and connected one by one. An elastic sheet 11 is welded and fixed on one side of the fixed block 12. One side of the elastic sheet 11 is tightly attached to the vertical plate 3. A display mechanism is provided on the top of the vertical plate 3. When in use, the principle of communicating vessels is utilized so that the liquid level inside the fixed pipe 2 is the same as the liquid level inside the ballast tank 1. Moreover, relative to the ballast tank 1, the area inside the fixed pipe 2 is small, so that the liquid level inside the fixed pipe 2 is less affected by the hull fluctuations. The floating block 7 floats on the upper end of the liquid level inside the fixed pipe 2. As the liquid level changes, the floating block 7 drives the fixed rod 8 to move up and down, so that the elastic sheet 11 moves along one side of the vertical plate 3 until it contacts the corresponding trigger switch 9, so that the corresponding warning light 10 is lit. In this way, the liquid level inside the ballast tank 1 is determined, thereby improving the accuracy of water level monitoring.

[0022] The display mechanism includes a display screen 4 and a control box 5. The display screen 4 is fixed to the top position of the vertical plate 3 by a mounting frame. The control box 5 is fixed to one side of the display screen 4 by bolts. The control box 5 is electrically connected to the trigger switch 9. When the trigger switch 9 on one side is contacted and triggered, the electrical signal is transmitted to the inside of the control box 5, and the specific water level value is displayed on the display screen 4, which makes it more convenient to observe the water level value.

[0023] Several fixing rings 6 are evenly welded and fixed inside the fixed tube 2. When in use, the water flowing into the fixed tube 2 first passes through the fixing ring 6. When the water passes through the fixed tube 2 too quickly, it is easy to cause a large liquid level difference inside the fixed tube 2. At this time, the water will impact the fixing ring 6 and reduce the water flow rate inside the fixed tube 2, thereby further ensuring the stability of the liquid level inside the fixed tube 2.

[0024] Working principle: When in use, the principle of communicating vessels is utilized to make the liquid level inside the fixed pipe 2 the same as the liquid level inside the ballast tank 1, and the area inside the fixed pipe 2 is small relative to the ballast tank 1, so that the liquid level inside the fixed pipe 2 is less affected by the hull fluctuations, and the floating block 7 floats on the upper end of the liquid level inside the fixed pipe 2. As the liquid level changes, the floating block 7 drives the fixed rod 8 to move up and down, so that the elastic sheet 11 moves along one side of the vertical plate 3 until it contacts the corresponding trigger switch 9, so that the corresponding prompt light 10 is lit, thereby determining the liquid level inside the ballast tank 1 and improving the accuracy of water level monitoring; when in use, the water source flowing into the fixed pipe 2 first passes through the fixed ring 6. When the water source passes through the fixed pipe 2 too quickly, it is easy to cause the liquid level difference inside the fixed pipe 2 to be too large. At this time, the water source will impact the fixed ring 6, reducing the flow rate of the water source inside the fixed pipe 2, thereby further ensuring the stability of the liquid level inside the fixed pipe 2.
