Description

Technical Field

[0001] This utility model relates to the field of marine instrumentation technology, specifically to a dual-channel redundant marine flow channel instrument with calibration function. Background Technology

[0002] Marine instruments are used to measure and control parameters and observe the objects being measured during ship operation. Inland waterway vessels are simpler, while ocean-going vessels are more complex, encompassing depth gauges, compasses, speedometers, positioning instruments, stress gauges, environmental monitoring instruments, as well as electrical instruments and automation instruments. They ensure accurate and safe navigation and normal operation of equipment. During ship operation, a large number of instruments are usually required to perform pressure testing to ensure the normal operation of various equipment.

[0003] Most existing marine instruments can easily and reliably detect the liquid's operating status. However, during use and operation, they are usually configured with a single channel corresponding to a single instrument. This setup makes it impossible to effectively calibrate the instruments during operation. A single instrument is prone to accuracy degradation when working continuously for a long period of time. Furthermore, the single-instrument setup makes it difficult to effectively confirm whether the malfunction is caused by a decrease in instrument accuracy, which is quite inconvenient. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a dual-channel redundant instrument for marine flow channels with calibration function. It has the advantages of extending the overall service life through redundancy settings and conveniently detecting the aging of the instrument. It solves the problems of not being able to effectively calibrate the instrument during operation, the tendency for a single instrument to experience accuracy degradation during continuous long-term operation, and the inability of a single instrument setting to effectively confirm whether the failure is caused by the degradation of instrument accuracy.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A marine flow channel dual-channel redundant instrument with calibration function includes a connecting component. The end of the connecting component is provided with a control valve having three liquid outlets. Two of the liquid outlets of the control valve are connected to instrument pipes with opposite liquid outlet inclination directions and the same angle. The end of the instrument pipes is connected to a detection instrument. The liquid outlets of the two detection instruments are connected to a manifold three-way valve. The last liquid outlet of the control valve is located between the two instrument pipes and is connected to a calibration channel. The calibration channel is a three-way pipe and its liquid outlet is connected to the connection point of the instrument pipe and the detection instrument. The calibration channel is provided with a pressure detection component extending to its outside.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the calibration channel is T-shaped, and the pressure detection component is arranged at the bend point of the calibration channel.

[0010] Furthermore, the pressure detection component includes a tension sensor fixed to the outside of the calibration channel. An elastic element is connected to one end of the tension sensor, and a connector extending into the calibration channel is fixedly connected to the other end of the elastic element. A shunt detection block is provided at the end of the connector, and a photoelectric switch for detecting the position of the connector is provided outside the calibration channel.

[0011] Furthermore, a sealing sleeve is fixedly installed inside the correction channel, and the sealing sleeve is fitted over the outside of the connector to form a seal.

[0012] Furthermore, the photoelectric switch is composed of multiple interruption sensors, and the connector is provided with an interruption plate extending to the inside of the photoelectric switch.

[0013] Furthermore, the control valve is an electrically controlled valve, and the control valve maintains communication with only a single liquid outlet at a time.

[0014] This utility model provides a dual-channel redundant instrument for marine flow channels with calibration function. By setting a connector, it can be installed with a manifold three-way valve to monitor the pipeline. Under normal conditions, the control valve and the manifold three-way valve can be switched to the same pipeline, so that the fluid passes through the detection instrument on that side, thereby realizing the detection of the fluid condition. During maintenance, it is only necessary to switch the control valve and the manifold three-way valve again to start the other detection instrument to start working alternately. This ensures that one side of the instrument can always be in standby mode, preventing fatigue damage caused by long-term use of a single instrument and increasing the overall service life.

[0015] Meanwhile, by setting up a calibration channel, during maintenance, the control valve can be switched to a state connected to the calibration channel, and then both inlet ends of the manifold three-way valve are connected to the outlet ends. At this time, the liquid reaches the two instrument pipelines through the calibration channel. By judging the readings at the two instrument pipelines and the output of the pressure detection component, it can be determined whether there is instrument aging. If aging is found, it can be replaced in standby mode.

[0016] In summary, this instrument has the advantages of extending its overall service life through redundant settings and being able to easily detect the aging of the instrument. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a dual-channel redundant instrument for marine flow channels with calibration function, including a connecting component 1. The end of the connecting component 1 is provided with a control valve 2 having three liquid outlets. Two of the liquid outlets of the control valve 2 are connected to instrument pipes 3 with opposite liquid outlet inclination directions and the same angle. The end of the instrument pipes 3 is connected to a detection instrument 4. The liquid outlets of the two detection instruments 4 are connected to a manifold three-way valve 5. The last liquid outlet of the control valve 2 is located between the two instrument pipes 3 and is connected to a calibration channel 6. The calibration channel 6 is a three-way pipe and its liquid outlet is connected to the connection point of the instrument pipes 3 and the detection instrument 4. The calibration channel 6 is provided with a pressure detection component 7 extending to the outside.

[0024] Furthermore, the calibration channel 6 is T-shaped, and the pressure detection component 7 is arranged at the bend point of the calibration channel 6.

[0025] This design effectively diverts the fluid, allowing it to easily pass through seven pressure detection components before reaching four of the two detection instruments.

[0026] Furthermore, the pressure detection component 7 includes a tension sensor 71 fixed to the outside of the calibration channel 6. An elastic element 72 is connected to one end of the tension sensor 71. A connector 73 extending into the inside of the calibration channel 6 is fixedly connected to the other end of the elastic element 72. A shunt detection block 74 is provided at the end of the connector 73. A photoelectric switch 75 for detecting the position of the connector 73 is provided outside the calibration channel 6.

[0027] In particular, the diversion detection block 74 is in the shape of a triangular pyramid, and the pressure detection component should also include a receiver, which receives, displays and communicates with other devices the status of the tension sensor 71 and the photoelectric switch 75. This configuration can effectively meet the fluid impact while effectively diverting the fluid.

[0028] The pressure detection component 7 is set up so that it first contacts the passing fluid through the diversion detection block 74. Then, the impact pressure applied by the fluid causes it to start moving and pushes the connector 73 to start moving. At the same time, the elastic element 72 starts to stretch. At this time, the tension sensor 71 can detect the current tension. By observing the change in tension, it can be known whether the current fluid flow is stable. At the same time, the current position change can also be detected by the photoelectric switch 75, so as to facilitate the judgment of the fluid pressure.

[0029] Furthermore, a sealing sleeve is fixedly installed inside the calibration channel 6, and the sealing sleeve is fitted over the outside of the connector 73 to form a seal.

[0030] The sealing sleeve maintains a tight seal during the movement of the connector 73, while also providing some damping to extend the effective pressure detection time. This ensures that the testing instrument 4 remains stable during the testing process, preventing inaccurate readings caused by sudden fluid impacts on the pipeline instruments.

[0031] Furthermore, the photoelectric switch 75 is composed of multiple interruption sensors, and the connector 73 has an interruption piece extending to the inside of the photoelectric switch 75.

[0032] The distance between two adjacent interruption sensors is less than the length of the interruption plate. This arrangement ensures that the interruption plate can always trigger at least one interruption sensor, guaranteeing overall sensitivity.

[0033] Furthermore, control valve 2 is an electrically controlled valve, and control valve 2 is only connected to a single liquid outlet at a time.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
