Abstract
Description
Technical Field
[0001] This invention belongs to the field of pressure pipeline leakage monitoring technology, and particularly relates to a marine diesel engine pressure pipeline leakage early warning device. Background Technology
[0002] As an important gas delivery component of the diesel engine turbocharger unit, the turbocharger pipeline is subject to large thermal expansion and contraction due to environmental climate, and leakage is prone to occur at the flange connection of the pipeline interface. Therefore, it is generally necessary to install a pipeline leakage early warning device for monitoring during use.
[0003] Currently, most existing pipeline leak warning devices use sensors to detect leaks at pipeline interfaces. However, this method is prone to failure after a malfunction. In addition, due to poor airtightness, the warning devices are prone to damage at the flange connection of the pipe when the pressure is too high, which can cause the diesel engine to lose power and damage the diesel engine, reducing its service life. Therefore, there is room for improvement. Summary of the Invention
[0004] The purpose of this invention is to provide a marine diesel engine turbocharger pipeline leakage early warning device to solve the above problems. This device can monitor the leakage of the turbocharger pipeline in real time and provide real-time alarm warnings, giving staff sufficient time to handle the problem and preventing the diesel engine's power from being affected due to delayed detection.

The fixing structure includes a first clamp and a second clamp that are fitted onto the guide tube and connected as one piece, a rubber sealing gasket connected inside the first clamp and the second clamp, and air guide tubes connected to both sides of the monitoring channel. Each air guide tube is connected to a one-way valve. The first clamp and the second clamp are provided with pressure grooves, and each air guide tube is connected to the pressure grooves to squeeze the tube openings and prevent excessive air leakage at the tube openings.
[0009] A further improvement is that the detection unit includes a relay connected to the outside of the monitoring box, a slide plate connected to the monitoring channel port, a first conductive piece connected to the slide plate, and a second conductive piece connected to the monitoring channel and corresponding to the first conductive piece. The first conductive piece and the second conductive piece are respectively connected to the positive and negative terminals of the relay.
[0010] When the pressurization pipeline leaks, gas flows from the guide pipe into the monitoring channel, pushing the slide plate to make conductive plate one and conductive plate two contact each other, activating the buzzer, and sending a signal to the control room via the wireless communication module for real-time alarm indication.
[0011] A further improvement is that the bottom of the monitoring box is connected to a card holder, and the side of the card holder is provided with positioning bolts for fixing the first card and the second card. The ends of the first card and the second card are provided with card slots, and each card slot is provided with a card post. The inner wall of the card holder is provided with a slot at the position of the corresponding card post. The inner wall of the slot is connected with a rubber abutment. The end of the card post is located in the slot. A compression spring is connected between the card holder and the first card and the second card, and the compression spring is respectively sleeved on the card post.
[0012] A further improvement is that after the locking pin is locked in the slot, it contacts the rubber abutment, and the compression spring is in a compressed state.
[0013] A further improvement is that the early warning terminal body includes a buzzer connected to the outer casing, a battery connected inside the outer casing, and a wireless communication module, wherein the wireless communication module, the buzzer, and the relay are all electrically connected to the battery.
[0014] A further improvement is that the device also includes a fixed bracket for installing the early warning terminal body and the monitoring box. Fixed studs are connected to the four corners of the early warning terminal body, and threaded holes are opened at the four corners of the monitoring box. During installation, the monitoring box and the early warning terminal body are connected as a whole by four fixed studs.
[0015] The beneficial effects of this invention are as follows:
[0016] (1) In this invention, the design of the detection unit can monitor the leakage of the booster pipe in real time and realize real-time alarm prediction, providing the staff with sufficient time to deal with it, thereby preventing the diesel engine's power from being affected due to untimely detection;
[0017] (2) Through the design of the fastener structure, the present invention can squeeze and buffer the first clamp, the second clamp and the pipe connection, to prevent the fastener structure from cracking due to excessive air pressure at the pipe opening.

Each air guide tube 410 is connected to a one-way valve 44. The first clamp 41 and the second clamp 42 are provided with a pressure groove 45. Each air guide tube 410 is connected to the pressure groove 45 to squeeze the tube opening and prevent excessive air leakage at the tube opening.
[0033] Combined with appendix Figure 2 As shown, in a preferred embodiment, the detection unit 3 includes a relay 31 connected to the outside of the monitoring box 2, a slide plate 32 connected to the port of the monitoring channel 21, a first conductive piece 33 connected to the slide plate 32, and a second conductive piece 34 connected to the monitoring channel 21 and corresponding to the first conductive piece 33. The first conductive piece 33 and the second conductive piece 34 are respectively connected to the positive and negative terminals of the relay 31.
[0034] When the pressurization pipeline leaks, gas flows from the guide pipe 22 into the monitoring channel 21. Under the action of air pressure, the slide plate 32 is pushed, causing the conductive sheet 33 and the conductive sheet 34 to come into contact with each other, activating the buzzer 11, and sending a signal to the control room through the wireless communication module 13 to achieve real-time alarm indication.
[0035] Combined with appendix Figure 2 As shown, in a preferred embodiment, the early warning terminal body 1 includes a buzzer 11 connected to the outer casing, a battery 14 connected inside the outer casing, and a wireless communication module 13. The wireless communication module 13, the buzzer 11, and the relay 31 are all electrically connected to the battery 14.
[0036] Combined with appendix Figure 2 To be continued Figure 4 As shown, in a preferred embodiment, the bottom of the monitoring box 2 is connected to a card holder 46. The side of the card holder 46 is provided with positioning bolts for fixing the first card 41 and the second card 42. The ends of the first card 41 and the second card 42 are provided with card slots 47. Each card slot 47 is provided with a card post 48. The inner wall of the card holder 46 is provided with a slot 461 at the position corresponding to the card post 48. The inner wall of the slot 461 is connected with a rubber abutment 462. The end of the card post 48 is located in the slot 461. A compression spring 49 is connected between the card holder 46 and the first card 41 and the second card 42. The compression spring 49 is respectively sleeved on the card post 48.

During installation, the fixing studs 12 and the threaded holes 23 are used to connect the monitoring box 2 and the early warning terminal body 1 into a whole, and then the fixing bracket 5 is connected to the engine compartment to realize the assembly and disassembly of the entire leakage early warning device.
[0039] As attached Figure 2 To be continued Figure 5 As shown, during installation and use: clip 41 and clip 42 of the fastener structure 4 are respectively fitted onto the pipe interface flange connection, and each air guide pipe 410 is connected to the pressure groove 45 on clip 41 and clip 42 respectively. The bottom of clip 41 and clip 42 is connected to the bracket 46 respectively.
[0040] When a leak occurs at the pipe port, gas flows from the guide pipe 22 into the monitoring channel 21. Under the action of air pressure, it is guided through the one-way valve 44 and the air guide pipe 410 into the pressure groove 45, which compresses the pipe port. At the same time, the design of the rubber sealing gasket 43, pressure groove 45, card seat 46, slot 461, rubber block 462, card groove 47, card post 48, and compression spring 49, in conjunction with the pressure groove 45, compresses and buffers the card part 1 41, card part 2 42 and the pipe port connection, preventing the fixing structure 4 from breaking at the pipe port connection due to excessive air pressure. This effectively prevents the diesel engine from being damaged due to power interruption caused by air leakage, and improves the service life of the diesel engine.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
