Description

Technical Field

[0001] The present invention mainly relates to the field of underwater engineering technology, and in particular to a small segment-use reciprocating telescopic transducer. Background Art

[0002] Wireless signals decay rapidly in water, so sound waves remain the dominant method for underwater signal transmission. Underwater AUVs and other underwater vehicles primarily transmit acoustic signals through their onboard transducers. As we all know, transducers are mostly made of ceramic, which is inherently fragile and requires protection from external objects. Transducers are primarily used for underwater acoustic communication and positioning. To prevent sound from being obstructed by objects, they must be mounted in a clear area. Therefore, transducers are often mounted on top of the AUV to maintain the transducer's transmission range.

[0003] However, due to the influence of wind and waves and ocean currents on the water surface, the transducer is often easily bumped during deployment and recovery; during storage and transportation, the exposed transducer is also often easily scratched and damaged, causing economic losses. Summary of the Invention

[0004] The invention purpose of this application is to provide a small segment reciprocating telescopic transducer, which can be extended and retracted in the navigation body compartment as needed, ensuring safety issues during use.

[0005] In order to achieve the invention purpose of this application, this application adopts the following metal scheme:

[0006] The present invention relates to a small-sized reciprocating telescopic transducer for segments, which comprises: a lead sleeve, a spring, a transducer, a lead plate, a bearing, a fixed sleeve, a cable, a limit column and a vulcanized rubber column. The lead sleeve is a cylindrical tube, which is fixed in an interference fit in a housing containing a battery compartment and an electronic equipment compartment. The circular lead plate is mounted in the lead sleeve, one end of two springs are respectively fixed on the symmetrical circumference of the upper end of the lead sleeve, and the other end are respectively fixed on the symmetrical circumference of the upper end of the lead plate. The transducer is mounted in the lead sleeve between the two springs and the lead plate and extends upward from the lead sleeve. A fixed sleeve is mounted at the lower end of the guide plate, and a plurality of screws are mounted on the fixed sleeve. The transducer and the fixed sleeve are fixed together by screws, the guide plate is clamped between the transducer and the fixed sleeve, and a bearing is installed on the circumference between the upper end of the guide plate and the lower end of the transducer. One end of the cable is fixed to the lower end of the transducer and is fixed in the center of the transducer, the guide plate and the fixed sleeve through a vulcanized rubber column. The other end of the cable passes through the lower end of the lead sleeve and the outer shell of the electronic equipment compartment and enters the electronic equipment compartment. Two symmetrical limit columns are respectively fixed on the circumference of the guide plate, and two special-shaped guide grooves are symmetrically opened on the circumference of the lead sleeve. The above-mentioned limit columns are respectively installed in the two special-shaped lead grooves and move up and down along the above-mentioned two special-shaped lead grooves.

[0007] The present invention relates to a small reciprocating telescopic transducer for segments, wherein: the special-shaped lead groove is composed of a straight groove at the upper end and an annular groove at the lower end, the straight groove is parallel to the axis of the lead sleeve, the upper end of the annular groove is connected to the lower end of the straight groove, and there is a retraction point on the annular groove that is higher than the lower end of the straight groove, and the limiting column moves up and down between the extension point at the upper end of the straight groove and the retraction point of the annular groove.

[0008] The present invention provides a small segment reciprocating telescopic transducer, wherein: the guide plate is sleeved on the upper end of the fixed sleeve.

[0009] The present invention provides a small segment reciprocating telescopic transducer, which further comprises a sealing ring which is mounted on the outer shell of the electronic equipment compartment where the other end of the cable enters.

[0010] The present invention provides a small segment reciprocating telescopic transducer, wherein the lead sleeve is made of non-metallic polytetrafluoroethylene material.

[0011] Compared with the prior art, the small segment reciprocating telescopic transducer of the present invention has the following advantages:

[0012] 1. The present invention has a compact and reasonable structure and is easy to operate. Through the ingenious design of the guide sleeve and the guide plate, a limited guide groove is opened on the guide sleeve. When the guide plate moves inside, it can drive the transducer to extend and retract. The special guide groove of the guide sleeve can be retracted with one press and extended with two presses, making it convenient to use reciprocatingly. The small-scale reciprocating telescopic transducer described in the present invention can effectively solve the problem that the traditional transducer can only be installed in a fixed position. When fixedly installed, the exposed transducer is easily damaged by collision with objects, causing economic losses.

[0013] 2. The small, reciprocating, telescopic transducer described in this invention has a simple structure and a compact size, with a maximum installation diameter of less than 35 mm. The transducer can be retracted and extended with a single push, making it highly marketable. Various underwater equipment platforms requiring transducer installations can be designed according to this patent, ensuring convenient and safe use and storage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] In order to more clearly express and understand the characteristics of the present invention, the present invention is further described below with reference to the accompanying drawings. Of course, the present invention can still be implemented in different description methods and is not limited to the specific implementation cases disclosed below.

[0018] like Figure 1 and Figure 2 As shown, the small-sized reciprocating telescopic transducer for segments of the present invention comprises: a lead sleeve 2, a spring 3, a transducer 4, a lead plate 5, a bearing 6, a fixing sleeve 7, a cable 8, a sealing ring 9, a limiting post 11, and a vulcanized rubber post 12. The lead sleeve 2 is a cylindrical tube made of non-metallic polytetrafluoroethylene material and is interference-fixed within a housing 1 between a battery compartment 13 and an electronic device compartment 14. The annular lead plate 5 is mounted within the lead sleeve 2. Two springs 3 have one end fixed to symmetrical circumferences of the upper end of the lead sleeve 2, and the other end fixed to symmetrical circumferences of the upper end of the lead plate 5. The transducer 4 is mounted within the lead sleeve 2 between the two springs 3 and the lead plate 5, extending upward from the lead sleeve 2. A fixing sleeve 7 is mounted at the lower end of the guide plate 5, and the guide plate 5 is sleeved onto the upper end of the fixing sleeve 7. Several screws 15 are installed on the fixing sleeve 7, and the transducer 4 and the fixing sleeve 7 are fixed together by the screws 15. The guide plate 5 is clamped between the transducer 4 and the fixing sleeve 7. A bearing 6 is installed on the circumference between the upper end of the guide plate 5 and the lower end of the transducer 4. One end of the cable 8 is fixed to the lower end of the transducer 4 and is fixed in the center of the transducer 4, the guide plate 5 and the fixing sleeve 7 through the vulcanized rubber column 12. The other end of the cable 8 passes through the lower end of the lead sleeve 2 and the outer shell 1 of the electronic equipment compartment 14 to enter the electronic equipment compartment 14. The sealing ring 9 is installed on the outer shell 1 of the electronic equipment compartment 14 where the other end of the cable 8 enters.

[0019] like Figure 1 and Figure 2As shown, two symmetrical limiting posts 11 are fixed on the circumference of the guide plate 5. Two special-shaped guide grooves 10 are symmetrically formed on the circumference of the guide sleeve 2. The limiting posts 11 are respectively installed in the two special-shaped guide grooves 10 and move up and down along the two special-shaped guide grooves 10. The special-shaped guide groove 10 consists of a straight groove 16 at the upper end and an annular groove 17 at the lower end. The straight groove 16 is parallel to the axis of the guide sleeve 2. The upper end of the annular groove 17 is connected to the lower end of the straight groove 16. The annular groove 17 has a retraction point higher than the lower end of the straight groove 16. The limiting posts 11 move up and down between the extension point at the upper end of the straight groove 16 and the retraction point of the annular groove 17.

[0020] During storage and transportation of the AUV, when the transducer 4 is not working, press the transducer 4. At this time, the spring 3 is stretched, and the transducer 4 moves downward along the mounting guide sleeve 2. At this time, the guide plate 5 and the transducer 4 move downward together. When the protruding limit column 11 on the guide plate 5 reaches the retraction point of the special-shaped guide groove on the mounting guide sleeve 2, release the pressure on the transducer 4. At this time, the transducer is in the retracted state and is recovered into the cabin.

[0021] When the transducer 4 needs to be used, the transducer 4 needs to be extended from the cabin, and the transducer 4 is pressed. At this time, the spring 3 is slowly retracted from the stretched state, and the transducer 4 moves down and then up along the installation guide sleeve 2. At this time, the guide plate 5 and the transducer 4 move down and then up. When the protruding limit column 11 on the guide plate 5 reaches the extension point of the special-shaped lead groove on the installation guide sleeve 2, the pressing of the transducer 4 is released. At this time, the transducer is in the raised state, and the transducer 4 can work normally. Figure 1 Press the transducer 4 again to retract it.

[0022] Therefore, the transducer 4 can be extended or retracted by repeatedly pressing according to the required scene, which not only ensures the safety of the transducer but also guarantees the use effect.

[0023] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
