Description

Technical Field

[0001] This utility model belongs to the field of ship ballast water management system commissioning technology, and specifically relates to a ship ballast water system pressure transmitter testing device. Background Technology

[0002] During navigation, the weight of a ship and the consumption of living supplies and fuel on board can cause changes in the ship's draft and center of gravity, which in turn affect the ship's navigation performance. In order to adjust for the impact of these changes in a timely manner and ensure the stability and safety of the ship, the ship's ballast water system has emerged. The pressure transmitter is an indispensable and important component of the ship's ballast water system, and its main function is to accurately measure the pressure parameters in the ballast water system.

[0003] For example, Chinese Patent No. CN210603725U discloses a pressure transmitter testing device for a ship ballast water management system, including a water storage box, a union, a pressure gauge, and a small booster pump. The small booster pump is installed on the water storage box. The water storage box is connected to a union for connecting to the pressure transmitter of the ship ballast water management system via a pressurization pipeline. A pressure gauge is installed on the pressurization pipeline.

[0004] The aforementioned patent utilizes a small pressurizing pump to pressurize the water storage box, enabling the testing of the pressure transmitter of the ship's ballast water management system according to the commissioning requirements. The test results are consistent with the commissioning requirements of the ship's ballast water management system, the test data is accurate, the operation is simple, and it saves time and effort. However, the wiring connection on both sides of the connector in the device is not stable enough, relying solely on the structure of the connector itself to achieve the wiring connection. When facing complex operating conditions such as swaying during ship operation, it is easy for the connection to loosen, which will not only affect the accuracy of the test data, but may also interfere with the commissioning of the entire ship's ballast water management system.

[0015] Secondly, this utility model, by providing a monitoring component on one side of the reinforcement mechanism, can mark the torsion wheel in the reinforcement mechanism. Once the marking block is misaligned with the infrared sensor, it can detect that the torsion wheel is loose and notify the external alarm device to sound an alarm.

[0021] Example

[0022] refer to Figures 1 to 4This embodiment describes a pressure transmitter detection device for a ship's ballast water system, comprising a water storage box 1. A small booster pump 2 is fixedly connected to one side of the water storage box 1. A booster pipeline 3 is fixedly connected to one side of the water storage box 1. A pressure gauge 4 is fixedly connected to one side of the booster pipeline 3. A relief valve 5 is provided on one side of the pressure gauge 4. A connecting seat 7 is provided on the side of the booster pipeline 3 away from the pressure gauge 4. Threaded heads 8 are fixedly connected to both sides of the connecting seat 7. Connecting sleeves 9 are provided on both sides of the connecting seat 7, and the pipeline is installed through the connecting sleeves 9. One side of the connecting sleeve 9 is provided with a threaded groove 10, and the screw head 8 is threadedly connected to the threaded groove 10. One side of the connecting sleeve 9 is fitted onto one side of the pressurization pipeline 3, and the other side of the connecting sleeve 9 is provided with a pressure transmitter body 6. One side of the connecting sleeve 9 is provided with a reinforcing mechanism 13, and one side of the reinforcing mechanism 13 is provided with a monitoring component 15. The small pressurization pump 2 is started to pressurize the water in the water storage box 1. The pressure transmitter body 6 is calibrated according to the data of the pressure gauge 4, which can quickly detect the pressure transmitter of the ship's ballast water management system.

[0023] refer to Figure 2-3 The connecting sleeve 9 is fixedly connected to both sides of the bracket 11, and a fixed frame 12 is fixedly connected to one side of the bracket 11. The reinforcement mechanism 13 and the detection component are both set on the fixed frame 12. The bracket 11 and the fixed frame 12 are used to install the reinforcement mechanism 13 and the detection component.

[0024] refer to Figure 3-4 The reinforcement mechanism 13 includes a lead screw 131, which is rotatably connected inside the fixed frame 12. A linkage block 132 is threaded onto the outer surface of the lead screw 131. A transmission rod 133 is fixedly connected to one side of the linkage block 132, and a pressure plate 134 is fixedly connected to one side of the transmission rod 133. An arc groove 135 is formed on one side of the pressure plate 134, and a rubber pad 136 is fixedly connected inside the arc groove 135. The rubber pad 136 is movably connected to one side of the pressurization pipeline 3 and the pressure transmitter body 6, respectively. The lead screw 131... A torsion wheel 14 is fixedly connected to one side of the device, and the torsion wheel 14 is provided with anti-slip texture. By setting a reinforcement mechanism 13, rotating the torsion wheel 14 drives the lead screw 131 to rotate, causing the linkage block 132 on the surface of the lead screw 131 to move. The linkage block 132 drives the transmission rod 133 to move, so that the clamping plate 134 gradually approaches the pressurizing pipeline 3 and the pressure transmitter body 6 pipeline. The rubber pad 136 in the arc groove 135 undergoes elastic deformation and tightly fits the surface of the pressurizing pipeline 3 and the pressure transmitter body 6, thereby reinforcing the joint formed by the connecting seat 7 and the connecting sleeve 9 and preventing it from detaching and affecting the detection work.

[0025] refer to Figure 4The monitoring component 15 includes an assembly plate 151, which is fixedly connected to one side of the torsion wheel 14 and rotatably connected to the fixed frame 12. A marking block 152 is provided on one side of the assembly plate 151. A side plate 153 is fixedly connected to one side of the fixed frame 12, and an infrared sensor 154 for detecting the marking block 152 is fixedly connected to one side of the side plate 153. By setting up the monitoring component 15, the infrared sensor 154, fixed to the side plate 153, continuously emits infrared light. When the marking block 152 aligns with the infrared sensor 154... When the infrared light is reflected or blocked by the marker block 152, the infrared signal received by the sensor changes, and the corresponding electrical signal is output. When the torsion wheel 14 becomes loose, it causes the assembly plate 151 and the marker block 152 to shift, and the marker block 152 is no longer aligned with the infrared sensor 154. The infrared signal received by the sensor returns to its initial state, and the electrical signal also changes accordingly. This signal change is transmitted to the external alarm device to trigger the alarm, avoiding serious consequences such as connection failure and detection interruption caused by the failure to deal with the loosening of the torsion wheel 14 in time, and greatly improving the safety of the detection device operation.

[0026] refer to Figure 3 The fixed frame 12 has a guide groove 16 inside, and a guide block 17 is slidably connected inside the guide groove 16. One side of the guide block 17 is fixedly connected to one side of the linkage block 132. By setting the guide block 17 and the guide groove 16, the movement direction of the linkage block 132 is restricted, so that it can only move linearly along the axis of the lead screw 131.

[0027] Operating principle and advantages: After the connecting sleeve 9 is connected to the pipelines on both sides, the operator holds the torsion wheel 14 and drives the lead screw 131 to rotate. When the lead screw 131 rotates, the linkage block 132, which is threaded to it, moves along the axis of the lead screw 131. The linkage block 132 drives the clamping plate 134 to gradually approach the pressurization pipeline 3 and the pressure transmitter body 6 through the transmission rod 133. When the clamping plate 134 contacts both, the torsion wheel 14 continues to rotate, so that the clamping plate 134 is further pressed. The rubber pad 136 in the arc groove 135 undergoes elastic deformation and tightly fits the surface of the pipeline connection between the pressurization pipeline 3 and the pressure transmitter body 6, ensuring the stability of signal transmission during the detection process. This ensures the accuracy of the detection data of the pressure transmitter in the ship's ballast water management system and guarantees the stability of the line connection. The commissioning of the ship's ballast water management system proceeded smoothly. When the torsion wheel 14 rotated, it caused the assembly plate 151 and the marker block 152 to rotate synchronously. The infrared sensor 154, fixed on the side plate 153, continuously emitted infrared light. When the marker block 152 was aligned with the infrared sensor 154, the infrared light was reflected or blocked, and the sensor output a corresponding electrical signal. Once the torsion wheel 14 became loose, it caused the assembly plate 151 and the marker block 152 to shift, and the marker block 152 was no longer aligned with the infrared sensor 154. The infrared signal received by the sensor returned to its initial state, the electrical signal changed and was transmitted to the external alarm device, triggering an alarm. This enabled real-time monitoring of the reinforcement status. Compared with manual inspection or periodic calibration, it can detect and resolve potential problems in advance, ensuring the smooth progress of the pressure transmitter testing.
