Description

Technical Field

[0001] The invention discloses an ultrasonic gas component detector, which relates to the technical field of signal receiving and detecting. Background Art

[0002] At present, pressure vessels for storing and transporting compressed gas are widely used in industry and life, such as cylinders, gas tanks, gas pipelines, closed gas chambers, etc. Due to various reasons, containers will have leaks and gas leaks will occur. It is estimated that the average amount of compressed gas lost in industry due to leakage is about 40%. Leakage not only causes waste of energy, but also pollutes the air if it is harmful gas. Traditional leak detection methods such as absolute pressure method, pressure difference method, bubble method, etc. are complicated to operate and require high technical personnel, and are not real-time. At present, the principle of leakage generating ultrasonic waves is widely used in industry for leak detection. Ultrasonic waves are a mechanical wave with a frequency generally exceeding 20KHz. Their energy is much greater than the energy of audible sound waves with the same amplitude, and they have strong penetrating power. Using ultrasonic waves to detect the location of gas leaks is not only simple, but also accurate and reliable.

[0003] According to the "An Ultrasonic Gas Composition Detector" disclosed in Chinese Patent Publication No. CN205426444U, a keyboard is arranged on the outside of the casing, which is mainly used to operate the equipment; a display is arranged on the front end of the casing, which can provide people with necessary display instructions; an ultrasonic probe is arranged on the upper part of the casing, which is mainly used to receive ultrasonic signals; a preamplifier is arranged inside, which can amplify the sensor signal; a bandpass filter is arranged next to the preamplifier, which can filter out noise; an amplifier is arranged opposite the bandpass amplifier, which further amplifies the signal; a mixer inside the casing can mix the signal into a certain frequency, which can become an acceptable signal; a power driver next to the mixer can provide large power support; and headphones outside the casing are mainly used to listen to abnormal sounds and detect sound sources.

[0004] However, the above device has the problem that it is inconvenient to move the detection machine and is not conducive to detecting multiple leakage locations. Summary of the invention

[0005] The object of the present invention is to provide an ultrasonic gas component detector to solve the problems raised in the above-mentioned background technology.

[0006] The object of the present invention is achieved in that: An ultrasonic gas component detector comprises a main structure and a protective structure, wherein the outer wall of the main structure is fixedly connected with the protective structure; The main structure comprises a detection machine body, a moving seat is fixedly connected to the bottom of the detection machine body, a servo motor is fixedly connected to the top wall of the moving seat, a driving gear is fixedly connected to the output end of the servo motor, a driven gear is meshed on the outer surface of the driving gear, a screw is fixedly connected to the outer wall of the driven gear, a connecting rod is threadedly connected to the outer surface of the screw, a bottom plate is fixedly connected to the bottom of the connecting rod, and a universal wheel is arranged at the bottom of the bottom plate; The protective structure comprises a sliding guide rail, the inner bottom wall of the sliding guide rail is fixedly connected with a guide rod, the outer surface of the guide rod is slidably connected with a sliding block, and the outer wall of the sliding block is fixedly connected with a protective plate.

[0007] Furthermore, the guide rod has a guiding function. By arranging the guide rod to guide the sliding block, the sliding block drives the protective plate to open and close.

[0008] Preferably, a support plate is provided at the bottom of the screw rod, and the support plate is fixedly connected to the inner wall of the movable seat.

[0009] Preferably, a display is provided on the front of the detection machine body, and a keyboard is provided below the display.

[0010] Preferably, a controller is fixedly connected to the outer wall of the movable seat, and the controller is electrically connected to the servo motor.

[0011] Preferably, a first magnetic strip is fixedly connected to the inner bottom wall of the sliding guide rail, and a second magnetic strip is fixedly connected to the bottom of the protective plate.

[0012] Preferably, the first magnetic stripe and the second magnetic stripe are matched in shape and size and are magnetically attracted to each other.

[0013] Preferably, the protective plate is made of a transparent plastic plate.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: First, the present invention starts the servo motor to drive the driving gear to rotate, the rotating driving gear drives the meshing driven gear to rotate, the driven gear drives the screw to rotate, and the rotating screw drives the connecting rod to move up and down, and also drives the bottom plate and the universal wheel to do lifting movement. The universal wheel is moved downward to contact the ground to support the mobile seat and the detection machine body, which is convenient for staff to carry. The universal wheel is moved upward to retract the universal wheel into the mobile seat, so that the bottom of the mobile seat contacts the ground, which avoids insufficient fixation of the universal wheel and movement during use, thereby increasing the stability of the detection machine body.

[0015] Second, the present invention drives the protective plate downward by the sliding block. When the protective plate completely blocks the display screen on the front of the detection machine body, the protective plate is fixed by the first magnetic strip on the sliding guide rail and the second magnetic strip on the protective plate. This prevents the display screen on the detection machine body from being accidentally touched or damaged by external force during use, and the protective plate made of transparent material will not block the data on the display, so that the staff can record the detection data without opening the protective plate.
