Description

Technical Field

[0001] This utility model relates to the field of engine testing technology, specifically to a vehicle engine oil passage leakage detection device. Background Technology

[0002] A vehicle engine is a heat engine specifically designed to provide power to motor vehicles. It is usually installed in various vehicles such as cars, motorcycles, trucks, and buses. It generates heat energy by burning fuel and then converts the heat energy into mechanical energy, thereby driving the vehicle's wheels to rotate and enabling the vehicle to move.

[0003] The applicant discovered through a search that a Chinese patent, "A Leak Detection Device for Automotive Engine Oil Pipes," with publication number "CN 217006248 U," mainly uses a collection unit installed below the oil pipe and a real-time detection component. It detects fuel flow in different sections of the oil pipe using a flow sensor to identify leaks, receiving signals immediately upon leakage and enabling timely intervention to reduce the risk of danger. The collection unit collects leaked fuel, triggering a secondary alarm via a level sensor to further reduce the probability of danger. However, this device is difficult to maintain, repair, or replace when the detection component malfunctions, significantly impacting work efficiency. Therefore, we propose a leak detection device for automotive engine oil passages. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0014] 1. This utility model is equipped with a quick-release component. When the detector needs to be disassembled, pressing the button pushes the push rod to push the top block, which in turn squeezes the locking block. This causes the locking block to overcome the elastic force of the first spring and exit from the locking hole of the fixing block, thus enabling the detector to be quickly removed from the pipeline. During installation, the detector is placed between the two sets of fixing blocks, and the locking block automatically engages with the locking hole under the action of the first spring, achieving quick installation. This improves the efficiency of detector installation and disassembly, facilitates maintenance, repair, or replacement, and enhances work efficiency.

[0015] 2. This utility model allows the operator to rotate the handwheel, which moves the threaded rod and flexibly adjusts the distance between the two sets of V-shaped clamps to ensure they fit the pipeline. During this process, the third spring continuously provides tension to the V-shaped clamps, keeping the clamping force on the pipeline stable and preventing displacement of the V-shaped clamps due to loosening of the threaded rod. This ensures the pipeline is securely fixed. At the same time, the buffer pad on the inner side of the V-shaped clamps prevents damage to the pipeline during the fixing process, thus achieving stable and reliable fixing of the pipeline. It can adapt to pipelines of different diameters and protect the pipeline from damage, improving the applicability of the detection device in different usage scenarios and its ability to protect the pipeline.

[0028] In embodiment two, the fixing component 5 includes a V-shaped clamp 51, a threaded rod 52, a third spring 53, a buffer pad 54, and a handwheel 55. Two sets of V-shaped clamps 51 are provided, located on the upper and lower sides of the pipe 1. One end of the threaded rod 52 is installed on the back of the V-shaped clamp 51. The two sets of threaded rods 52 respectively penetrate the surfaces of the mounting bracket 4 and the support bracket 41. The third spring 53 is sleeved on the outside of the threaded rod 52, with one end of the third spring 53 installed on the back of the V-shaped clamp 51. The other end is installed on the inner side of the support frame 41 and the mounting frame 4. The handwheel 55 is installed on the other end of the threaded rod 52.

The support legs on both sides of the mounting frame 4 provide stable support for the entire device.

[0030] Working principle:

[0031] First, after the detection device starts working, the support legs on both sides of the mounting bracket 4 provide stable support for the device. The mounting bracket 4 below the pipe 1 and the fixing component 5 inside the support bracket 41 above it, by turning the handwheel 55 to drive the threaded rod 52, adjust the distance between the two sets of V-shaped clamps 51, and tightly clamp the pipe 1. The third spring 53 continuously provides tension to prevent the threaded rod 52 from loosening. The buffer pad 54 inside the V-shaped clamp 51 protects the pipe 1 from damage. Next, the detector 2 begins to function. The quick-release component 3 on the outside of the detector 2, through the button 38 and the push rod 37, ... The cooperation of the top block 35, the second spring 36, the locking block 34, and the first spring 32 allows for easy installation and removal of the detector 2, facilitating maintenance and repair. The limiting grooves and limiting blocks in the placement hole and locking hole ensure the smooth operation of the locking block 34 and the top block 35. When the engine oil passage is working, the detector 2 monitors the oil passage condition in real time. If there is a leak in the oil passage, the oil will enter the collection box 45 through the drain pipe 44 via the oil leakage hole 43 on the surface of the mounting bracket 4. The liquid level alarm will issue a timely warning, and the baffle 42 above the mounting bracket 4 will prevent oil from splashing. At this point, the entire working process is complete.
