DETAILED DESCRIPTION
[0008] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0010] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.
[0011] See also Figure 1, which is a schematic diagram of a three-dimensional structure of the present invention; the present application optimizes and improves an axial ultrasonic transducer in the prior art. The capsule is made of a highly elastic material and can fit tightly against the outer shell of the transducer, effectively preventing external liquid, gas or impurities from entering and protecting internal components from damage. The capsule has good wear resistance and can withstand the vibration and friction of the transducer when it is working. When the capsule is inflated, its volume will expand and drive the moving seat fixed at the bottom of the capsule to slide to both sides, which not only provides space for the expansion of the capsule, but also applies additional pre-tightening force to the electronic ring through the linkage effect of the mechanical structure. As the degree of inflation of the capsule increases, the pre-tightening force will increase accordingly, thereby ensuring close contact and stable fixation between the internal components of the transducer. The expansion of the capsule also further enhances the sealing effect inside the transducer. As the pre-tightening force increases, the contact surfaces between the components become tighter, reducing the risk of gas or liquid leakage. , which provides a strong guarantee for the stable operation of the transducer. One end of the heat-conducting column is connected to the bottom of the moving seat, and the other end is placed in the cavity of the capsule. Its main function is to conduct the heat generated during the operation of the transducer from the oil cavity to the capsule. Through the effect of heat conduction, the heat-conducting column effectively reduces the temperature in the oil cavity and prevents the performance degradation or damage caused by excessive temperature. At the same time, the expansion of the capsule also partially absorbs the heat, further enhancing the heat dissipation capacity of the transducer. Heat conduction indirectly helps to maintain the stability of the transducer structure and the consistency of the preload by controlling the temperature distribution inside the transducer. The cooperation between the capsule, the moving seat and the heat-conducting column not only improves the preload, but also enhances the sealing effect and heat dissipation capacity of the transducer. The combined effect of these factors significantly improves the overall performance and working stability of the transducer. Under long-term and high-intensity working conditions, the transducer can still maintain stable output and reliable working state.

After being inflated, the bladder 410 can fit tightly to the surface of structures of various shapes to achieve an excellent sealing effect. The support assembly 200 includes a support frame 210, a flange connection seat 220, and a flange plate 230; A plurality of support frames 210 are fixedly connected to the bottom of the cover body 110. The support frames 210 are rectangular bodies, and a flange connection seat 220 is fixedly connected to the bottom of the support frames 210. The flange connection seat 220 is a rectangular body, and a flange plate 230 is fixedly connected to the bottom of the flange connection seat 220; The flange plate 230 is a disc-shaped body; The connection assembly 300 includes a barrier 310, a top plate 320, a connecting rod 330, an electronic ring 340, an insulating sleeve 350, an electrode sheet, and a bottom plate 360; The barrier body 310 is connected to the bottom wall of the oil chamber 130, the barrier body 310 is a cylindrical body, and a top plate 320 is disposed at the bottom of the barrier body 310; The top plate 320 is a cylindrical body, a through hole is formed on the top of the top plate 320, and an electronic ring body 340 is fixedly connected to the bottom of the top plate 320; The electronic ring body 340 is a cylindrical body, a through hole is formed on the top of the electronic ring body 340, and a bottom plate 360 is fixedly connected to the bottom of the electronic ring body 340; The bottom plate 360 is a cylindrical body, and a connection hole is opened on the top of the bottom plate 360; The through holes of the top plate 320 and the electronic ring body 340 and the connecting holes of the bottom plate 360 are all provided with connecting rods 330; The connecting rod 330 is a cylindrical rod, and the bottom end of the connecting rod 330 has a threaded structure. An insulating sleeve 350 is provided on the connecting rod 330 between the top plate 320 and the bottom plate 360; The insulating sleeve 350 is a cylindrical body; The mounting hole 111, the oil chamber 130 and the connecting rod 330 are all coaxially arranged; The barrier body 310 , the top plate 320 , the electronic ring body 340 and the bottom plate 360 are all coaxially arranged.
[0013] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: The capsule 410 is made of a soft and elastic material, which can ensure that the capsule 410 can be deformed to adapt to the unevenness of the sealing surface when subjected to external force, thereby improving the sealing effect. When the bolt 120 is tightened, it will apply a pre-tightening force to the capsule 410. This force acts along the axial direction of the bolt 120 to ensure close contact between the components inside the transducer. Under the action of the pre-tightening force, the capsule 410 will be deformed and its internal space will be compressed, thereby causing the gas pressure inside the capsule 410 to increase. After the capsule 410 is inflated, the increase in the internal gas pressure helps to enhance the sealing effect between the capsule 410 and other contact surfaces, which can prevent gas or liquid leakage and ensure the stability of the internal environment of the transducer. As the gas pressure inside the capsule 410 increases, the pressure of the capsule 410 on the electronic ring 340 will also increase accordingly. The increase in pressure helps to ensure that the electronic ring body 340 maintains a stable position inside the transducer and reduces displacement caused by vibration or external impact. After the capsule 410 is inflated, the internal gas pressure can also serve as an additional force transmission medium to more evenly transmit the preload force applied by the bolt 120 to the electronic ring body 340, which helps to reduce the stress concentration caused by uneven distribution of the preload force and improve the overall performance and reliability of the transducer. By applying the preload force through the bolt 120 and causing the capsule 410 to be inflated, the axial ultrasonic transducer can achieve a tighter seal and a more uniform distribution of the preload force, which helps to improve the energy conversion efficiency of the transducer, reduce vibration noise and extend the service life. In some harsh working environments, it can ensure close contact and stable performance between the components inside the transducer, thereby improving the environmental adaptability and reliability of the transducer.
[0014] Embodiment 2: In order to further improve the applicability and convenience of the use of an axial ultrasonic transducer of the present application, the bottom of the capsule of the embodiment of the present application is optimized and improved, specifically: like Figure 4 As shown, the sealing assembly 400 further includes a moving seat 420; The movable seat 420 is fixedly connected to the bottom of the capsule 410, and the cross section of the movable seat 420 is a rectangular body; The movable seat 420 needs to withstand greater pressure and wear, so it is made of stainless steel with good corrosion resistance and wear resistance.
[0015] When the capsule 410 expands due to pressure or internal air pressure, the movable seat 420 will move to both sides, so that the sealing component can adapt to the slight changes in the sealing surface and fill the possible gaps through the displacement of the movable seat 420, thereby further improving the tightness of the seal. It not only provides space for the expansion of the capsule 410, but also applies additional pre-tightening force to the electronic ring body 340 through the linkage effect on the mechanical structure. The sliding of the movable seat 420 actually applies a dynamic pre-tightening force to the electronic ring body 340. As the capsule 410 is inflated, the movable seat 420 continues to slide to both sides, and the pre-tightening force on the electronic ring body 340 gradually increases. This dynamic pre-tightening force adjustment mechanism helps to ensure that the electronic ring body 340 always maintains a stable position and close contact during the operation of the transducer. The sliding of the movable seat 420 also helps to improve the sealing effect inside the transducer. As the preload increases, the contact surfaces between the components inside the transducer become tighter, thereby reducing the risk of gas or liquid leakage. At the same time, the inflation of the capsule 410 itself also helps to improve the sealing performance, because the inflated capsule 410 can better fill and seal the tiny gap between the contact surfaces. Through the cooperation between the capsule 410 and the movable seat 420, the axial ultrasonic transducer can achieve more precise preload control and better sealing effect, which helps to improve the energy conversion efficiency of the transducer, reduce vibration noise and extend the service life, so that the axial ultrasonic transducer can better adapt to different working environments and conditions. Whether in high temperature, high pressure or strong vibration environment, the transducer can maintain stable performance and reliable working state.
[0016] Embodiment 3: In order to further improve the applicability and convenience of the self-settling sand separation device for shale gas extraction of the present application, the present application embodiment optimizes and improves the capsule and the movable seat, specifically: like Figure 5 As shown, the sealing assembly 400 further includes a heat-conducting column 430; One end of the heat-conducting column 430 is fixedly connected to the cavity of the capsule 410, and the other end of the heat-conducting column 430 is fixedly connected to the bottom of the movable seat 420. The heat-conducting column 430 is a cylindrical body; The heat-conducting column 430 needs to have good thermal conductivity and corrosion resistance, so it is made of a copper alloy with excellent thermal conductivity and corrosion resistance.
[0017] One end of the heat-conducting column 430 is connected to the bottom end of the movable seat, and the other end is placed in the cavity of the capsule 410. The heat-conducting characteristics of the heat-conducting column 430 are utilized to introduce the heat generated in the oil cavity into the capsule 410. When the oil in the oil cavity heats up due to the heat accumulation during the working process, the heat-conducting column 430 transfers the heat to the capsule 410. The efficient heat-conducting performance of the heat-conducting column 430 ensures the rapid and uniform transfer of heat. With the introduction of heat, the temperature inside the capsule 410 gradually increases, causing the material of the capsule 410 to expand due to heat. This expansion not only increases the volume of the capsule 410, but also increases the gas pressure inside it accordingly. The expansion of the capsule 410 further fills the tiny gap that may exist inside the transducer, thereby improving the sealing effect. As the capsule 410 expands, its preload force on the electronic exchanger 340 will also increase accordingly. The increase in preload force helps to maintain the stability of the electronic exchanger 340 inside the transducer and reduce the displacement caused by vibration or external impact. The heat conducting column 430 conducts the heat in the oil cavity to the capsule 410, which helps to reduce the heat accumulation in the oil cavity, thereby reducing the impact of the temperature and viscosity changes of the oil on the performance of the transducer. By optimizing the heat transfer and preload distribution, the overall performance of the axial ultrasonic transducer is improved.
