[0002] Type-IV hydrogen storage bottles are the type of hydrogen storage bottles for hydrogen-powered vehicles that are most likely to be widely promoted at present. As a sealed container that directly contacts and isolates high-pressure hydrogen and a mold for fiber winding, the plastic inner liner is an important part of the Type-IV hydrogen storage bottle and also the starting stage of the entire manufacturing process of the Type-IV hydrogen storage bottle. At present, the domestic has preliminarily studied the forming process of the plastic inner liner of on-vehicle hydrogen storage bottles, but there are problems such as low yield rate and poor performance stability in mass production, and ultrasonic testing methods need to be used to control the manufacturing quality of the plastic inner liner.

[0003] The plastic inner liner welding technology is an important process link in the industrial production of Type-IV hydrogen storage bottles. The welding quality of the thin-walled plastic inner liner is easily affected by various factors such as the positioning of the welding cross-section, the deformation of the welding cross-section, and the welding process parameters, which increases the difficulty of controlling the consistency of the quality of the welded formed products.

[0004] For the inner liner of the Type-IV hydrogen storage bottle with characteristics such as large volume and thin wall, due to the existence of buoyancy, it is easy to cause the deformation and inclination of the inner liner in the water immersion detection method, which is not conducive to stable detection. The difficulty of the water spray method lies in the need to design a non-standard fixture for the used probe to achieve the fixation of the probe and the ejection of the water flow that meets the coupling conditions.

[0005] Therefore, how to design a water spray method ultrasonic phased array probe fixture structure for the used probe to achieve the fixation of the probe and the ejection of the water flow that meets the coupling conditions, reduce the detection difficulty, and improve the detection accuracy and stability has become a problem that must be solved in relevant production activities. Summary of the Invention

[0041] Furthermore, in this embodiment, after the upper water inlet cover 1, the rectifying chamber middle cover 2, and the lower water spray cover 5 are assembled from top to bottom, the three jointly form an internal space with a single inlet and a single outlet, and the transverse cross-section of the internal space transitions from a circle to a rectangle that fits the shape of the phased array effective area of the ultrasonic phased array probe 4; Through the internal space provided by the water inlet upper cover 1, the rectifier chamber middle cover 2, the water outlet lower cover 5 and the ultrasonic phased array probe 4, the ultrasonic phased array probe 4 can be completely coupled with the water, so that the ultrasonic phased array probe 4 is coupled and connected inside the outer shell part, which is convenient for the precise use of the ultrasonic phased array probe 4.

[0047] Furthermore, in this embodiment, when the housing part and the probe mounting seat part are in the assembled state, the transition mounting plate 201 is suspended above the inside of the rectifying chamber middle cover 2 of the housing part through the receiving bolt 204, and a gap is formed between the bottom of the transition mounting plate 201 and the upper part inside the rectifying chamber middle cover 2. After the water entering from the water inlet upper cover 1 passes through the transition mounting plate 201 and the pressing plate 202 covered with through holes 6, the flow direction of the water at the junction of the transition mounting plate 201 and the rectifying chamber middle cover 2 changes from downward to horizontal, exhausting the air in the surrounding space of the ultrasonic phased array probe 4 and completely covering the water flow under normal working conditions. Through the cooperative setting of the rectifying chamber middle cover 2 and the water spraying port lower cover 5, the water spraying port lower cover 5 facilitates the diversion and discharge of water and is also beneficial to the use of the ultrasonic phased array probe 4.

The ultrasonic phased array probe fixture for a water-jet ultrasonic non-destructive testing system according to claim 2, characterized in that: Corresponding concave-convex structures are provided between the contact surfaces of the water inlet upper cover (1) and the rectifying chamber middle cover (2), and between the contact surfaces of the rectifying chamber middle cover (2) and the water outlet lower cover (5).

5. The ultrasonic phased array probe fixture for a water jet ultrasonic non-destructive testing system according to claim 1, characterized in that: A groove (2011) matching the outer contour of the ultrasonic phased array probe (4) is provided inside the transition mounting plate (201), and the ultrasonic phased array probe (4) is positioned and fit in the transition mounting plate (201) through the groove (2011).

6. The ultrasonic phased array probe fixture for the water-jet ultrasonic non-destructive testing system according to claim 1, characterized in that: When the shell part and the probe mounting seat part are in an assembled state, the structure in the internal space after the two are assembled forms a water flow channel, and water entering from the water inlet upper cover (1) passes through the transition mounting plate (201) and the pressing plate (202) covered with through holes (6), so that water bubbles around the ultrasonic phased array probe (4) are eliminated.

7. An ultrasonic phased array probe fixture for a water-jet ultrasonic non-destructive testing system according to claim 1, characterized in that: In the assembled state of the housing part and the probe mounting seat part, the transition mounting flat plate (201) is suspended above the inside of the rectifying chamber middle cover (2) in the housing part by means of the receiving bolt (204), and a gap is formed between the bottom of the transition mounting flat plate (201) and the upper part inside the rectifying chamber middle cover (2); After the water entering from the water inlet upper cover (1) passes through the transition mounting flat plate (201) and the pressing flat plate (202) covered with through holes (6), the flow direction of the water at the junction of the transition mounting flat plate (201) and the rectifying chamber middle cover (2) changes from downward to horizontal, so as to remove the air in the space around the ultrasonic phased array probe (4) and completely cover the water flow.
