Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] Combine Figure 1-Figure 5In an embodiment of the present invention, a sliding sealing method includes a slide groove 2 provided on the side wall of a water tank 1, and a thin steel belt 8 and a self-lubricating thick silicone strip 11 are fixedly connected at both ends of the slide groove 2, the thin steel belt 8 and the self-lubricating thick silicone strip 11 are fixedly connected, and the thin steel belt 8 is located inside the water tank 1, and the self-lubricating thick silicone strip 11 cooperates with the slide groove 2; it also includes a wedge-shaped slider assembly 4, the wedge-shaped slider assembly 4 is arranged through the slide groove 2, and the part of the wedge-shaped slider assembly 4 located in the water tank 1 is provided with a symmetrically arranged upper pressure wheel 14 and lower pressure wheel 15, the thin steel belt 8 and the self-lubricating thick silicone strip 11 both pass through the upper pressure wheel 14 and the lower pressure wheel 15, and are fitted with the wedge-shaped slider assembly 4; an annular probe 7 is connected to both sides of the wedge-shaped slider assembly 4, and an external linear motion module (not shown in the figure) is connected to the outside of the wedge-shaped slider assembly 4;

[0031] The method comprises the following steps:

[0032] S100, passing the thin steel strip 8 and the self-lubricating thick silicone strip 11 through the middle of the wedge-shaped slider assembly 4, and installing the wedge-shaped slider assembly 4 on the chute 2 on the side wall of the water tank 1, and installing the annular probe 7 on the wedge-shaped slider assembly 4;

[0033] S200, the signal line of the ring probe 7 is connected and extended outward through the wedge-shaped slider assembly 4;

[0034] S300 , utilizing the external linear motion module to drive the wedge-shaped slider assembly 4 to move up and down to perform up and down scanning in water.

[0035] In the present invention, the thin steel belt 8 and the self-lubricating thick silicone strip 11 pass through the partial section of the slide groove 2 of the wedge slider assembly 4 without being sealed. At this time, the wedge slider assembly 4 can just seal this part. When the wedge slider assembly 4 moves up and down, it cooperates with the thin steel belt 8 and the self-lubricating thick silicone strip 11 to ensure that the slide groove 2 is always in a sealed state and water leakage will not occur.

[0036] An overflow trough 3 is provided on the water tank 1 below the chute 2. When the wedge-shaped slider assembly 4 slides, a small amount of water will inevitably seep out. The seeped water can flow into the overflow trough 3 below and be collected and cleaned subsequently.

[0037] In the present invention, the external linear motion module can be a linear motor or other components that can achieve reciprocating linear motion, which will not be described in detail here.

[0038] The width of the thin steel strip 8 is greater than the width of the chute 2, the width of the self-lubricating thick silicone strip 5 is equal to the width of the chute 2, and sealing protrusions 9 are provided on both side walls of the self-lubricating thick silicone strip 5, see Figure 2The thin steel strip 8 is larger than the self-lubricating thick silicone strip 11. The self-lubricating thick silicone strip 11 is precisely engaged with the chute 2 to seal the chute 2, while the thin steel strip 8 can press the self-lubricating thick silicone strip 11 to prevent the water in the water tank 1 from flowing out. The sealing protrusions 9 arranged on both sides of the self-lubricating thick silicone strip 11 can effectively prevent water leakage.

[0039] See also Figure 3 and Figure 4 The wedge-shaped slider assembly 4 includes a self-lubricating plastic base 10, which is connected to a triangular connecting block 12 through a self-lubricating silicone slider 11 (the triangular connecting block 12 here is also made of self-lubricating plastic). The width of the self-lubricating plastic base 10 and the triangular connecting block 12 is greater than the width of the slide groove 2; the two side surfaces of the triangular connecting block 12 are provided with connecting tubes 17 for connecting the annular probe 7, and the signal line of the annular probe 7 extends outward through the connecting tube 17 and the signal outlet tube 6 arranged on the outside of the self-lubricating plastic base 10.

[0040] During assembly, the triangular connecting block 12 can be placed in the water tank 1 first, and placed in the middle position between the thin steel belt 8, the self-lubricating thick silicone strip 11 and the inner wall of the water tank 1. At this time, the thin steel belt 8 and the self-lubricating thick silicone strip 11 are partially matched with the grooves 13 set on the surface of the triangular connecting block 12. Then, the self-lubricating silicone slider 11 and the self-lubricating plastic base 10 are connected into a whole by bolts, and then the upper pressing wheel 14 and the lower pressing wheel 15 and the annular probe 7 are assembled. The probe signal line of the annular probe 7 is inserted from the connecting tube 17 and then passes through the triangular connecting block 12 and the self-lubricating plastic base 10 and extends from the signal line outlet tube 6;

[0041] The upper pressing wheel 14 and the lower pressing wheel 15 provided here can make the thin steel belt 8 and the self-lubricating thick silicone strip 11 fit tightly against the inner wall and the chute of the water tank 1, which can effectively ensure that the water in the water tank 1 will not flow out.

[0042] Sealing protrusions (not shown in the figure) are provided on both sides of the self-lubricating silicone slider 10, which can ensure that the self-lubricating silicone slider 10 and the slide groove 2 fit tightly and slide, so that the wedge-shaped slider assembly 4 can be clamped on the slide groove 2 and slide up and down.

[0043] The width of the groove 13 is greater than the width of the self-lubricating thick silicone strip 5 .

[0044] The upper pressing wheel 14 and the lower pressing wheel 15 are connected to the triangular connecting block 12 through a connecting rod 16, so that the upper pressing wheel 14 and the lower pressing wheel 15 can be easily disassembled. Figure 4It can be seen that there are requirements for the positions of the upper pressure wheel 14 and the lower pressure wheel 15, and a certain inclination angle needs to be maintained. Therefore, the connection between the connecting rod 16 and the triangular connecting block 12 here also needs to be maintained at a certain angle. Specifically, this can be achieved by setting an anti-rotation groove and an anti-rotation protrusion on the connecting rod.

[0045] An application of the sliding sealing method as described above in a tomographic ultrasound system.

[0046] In the present invention, the overall structure is compact and solves the sliding sealing problem. As for the mechanical fatigue wear problem, a self-lubricating plastic base and a self-lubricating thick silicone strip material are used. Regular replacement is quick and convenient, and maintenance is fast and low-cost. In addition, the sealing problem of the probe signal line and the shaking problem of the ring probe 7 can be effectively solved.

[0047] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
