Description

Technical Field

[0001] The utility model relates to a leakage testing device, in particular to an intake manifold leakage testing alarm device based on ultrasonic waves. Background Art

[0002] The automobile manifold refers to the intake pipe from the carburetor or throttle body to the cylinder head intake duct. Its function is to distribute the air and fuel mixture from the carburetor or throttle body to the intake duct of each cylinder. In order to ensure the good sealing performance of the manifold, testing equipment is used to test the sealing performance of the manifold. When the existing technology testing equipment detects a product leak, it is not possible to observe it intuitively with the naked eye, and the detection effect of the product is poor, which reduces the product detection quality and reduces the product production capacity. At the same time, the detection operation steps are more numerous, resulting in labor waste.

[0003] To this end, we propose an ultrasonic-based intake manifold leakage test alarm device to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide an intake manifold leakage test alarm device based on ultrasonic waves to solve the problems raised in the above background technology.

[0005] The purpose of the utility model is achieved through the following technical scheme: an intake manifold leakage test alarm device based on ultrasound, comprising a base, a fixing frame, a left connecting flange, an intake pipe, a movable frame, a right connecting flange, an exhaust pipe, an intake manifold, a soundproof cover, a suspension fixing frame, an ultrasonic detector, an ultrasonic transmitting port, a signal receiving probe, a movable motor, a slide rail and a human-machine operation controller, wherein the fixing frame is fixedly mounted on the left end of the base; the left connecting flange is fixedly mounted on the fixing frame, and its right end is connected to the intake manifold, and the other end is connected to the intake pipe; the movable frame is moved and mounted on the right end of the base by a stepper motor; the right connecting flange is fixedly mounted on the movable frame, and its left end is connected to the intake manifold, and the other end is connected to the exhaust pipe; the soundproof cover is fixedly mounted on the base; the slide rail is fixedly mounted on the top of the soundproof cover through the suspension fixing frame; the ultrasonic detector is slidably mounted on the slide rail by a movable motor; the ultrasonic detector is provided with an ultrasonic transmitting port and a signal receiving probe; the human-machine operation controller is mounted on one side of the base.

[0006] Furthermore, the opening of the air inlet pipe is larger than the opening of the air outlet pipe.

[0007] Furthermore, the air outlet pipe is a "Y"-shaped structure.

[0008] Furthermore, solenoid valves are provided on the air inlet pipe and the air outlet pipe.

[0009] Furthermore, the soundproof cover is provided with an openable operating door and a fixed observation window.

[0010] Furthermore, the signal receiving probe is a trumpet-shaped structure.

[0011] Furthermore, the human-machine operation controller is electrically connected to the solenoid valve, ultrasonic detector, moving motor and stepping motor on the air inlet pipe and the air outlet pipe.

[0012] Furthermore, the human-machine operation controller is also provided with an alarm device.

[0013] Compared with the prior art, the beneficial effect of the present invention is that the new type of intake manifold leakage test alarm device based on ultrasound is fixedly connected through the left connecting flange and the right connecting flange, the sound insulation cover is closed, the sensitivity of the ultrasonic detector is adjusted by the human-machine operation controller to measure the background signal, and the intake and outlet volumes of the intake pipe and the outlet pipe are controlled by the human-machine operation controller. Since the orifice of the intake pipe is larger than the orifice of the outlet pipe, and the outlet pipe is a "Y"-shaped structure, a certain high pressure will be formed in the intake manifold. When the high-pressure gas passes through the leakage point, high-frequency sound waves will be generated. The human-machine operation controller controls the mobile motor to drive the ultrasonic detector to move on the intake manifold to collect sound wave signals. Through test comparison, if the collected sound wave signal data are in the same range, it can be judged that there is no leakage in the intake manifold. If the collected sound wave signal data are not in the same range, it can be judged that there is a leakage in the intake manifold, which will trigger the alarm device. By comparing the difference in the sound wave signals, the leakage point can be accurately located. The test accuracy is higher and the speed is faster, which optimizes the quality of the tested products, greatly increases production capacity, saves labor to a certain extent, is easy to use, and does not pollute the environment.

[0018] It is worth mentioning that the orifice of the air inlet pipe 4 is larger than the orifice of the air outlet pipe 7. The air outlet pipe 7 is a "Y"-shaped structure. Solenoid valves are provided on the air inlet pipe 4 and the air outlet pipe 7. The soundproof cover 9 is provided with an openable operating door and a fixed observation window.

If the collected sound wave signal data are not in the same range, it can be judged that there is a leakage in the intake manifold 8, and the alarm device will be triggered. By comparing the difference in the sound wave signals, the leakage point can be accurately located.
