Description

Technical Field

[0001] The present application relates to the technical field of electric energy transmission, and in particular to a modular multi-relay wireless energy transmission system structure. Background Art

[0002] Online monitoring equipment on transmission lines is mainly used for real-time monitoring and data analysis of transmission lines and their surrounding environment. For example, online monitoring equipment can capture real-time images of transmission lines and their surrounding environment through high-definition cameras, so as to promptly discover and respond to potential risks such as human damage and changes in the natural environment. For another example, online monitoring equipment can collect meteorological data including temperature, humidity, wind speed, wind direction, etc. through sensors to predict and prevent line failures caused by severe weather.

[0003] At present, online monitoring equipment is usually powered by batteries, photovoltaic power generation, wind power generation, etc. However, battery power needs to be replaced by manual disassembly and installation, while photovoltaic power generation and wind power generation are restricted by natural conditions and are difficult to maintain high efficiency for a long time. Among related technologies, wireless power transmission solves the problems of battery replacement and natural conditions in the power supply of online equipment, and provides stable and reliable power supply for online monitoring equipment of transmission lines.

[0004] However, current wireless power transmission devices usually integrate the transmitting coil, relay coil, receiving coil and core rod into an insulated package. For example, a Chinese patent (CN118249527A) discloses a multi-relay magnetic coupling wireless power supply system based on optimal efficiency conditions. After the transmitting coil and the receiving coil are insulated and packaged (such as epoxy resin material), wires need to be led out to connect to an external circuit (such as an inverter circuit or a rectifier circuit). Not only is the process difficult to implement, but after long-term outdoor service, the wire lead-out position is prone to cracking, and water vapor will invade the interior of the insulation layer through the cracks, eventually leading to a safety hazard of insulation failure in the entire system.

[0064] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or illustration."

The following description is given to enable any person skilled in the art to implement and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the invention can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0065] The embodiments of the present application provide a modular multi-relay wireless energy transmission system structure, which is described in detail below.

[0066] First, see Figure 1 , Figure 1 A structural schematic diagram of a modular multi-relay wireless energy transmission system structure in an embodiment of the present application is shown, wherein the modular multi-relay wireless energy transmission system structure includes a relay energy transmission component 10, a transmitting component 20 and a receiving component 30.

[0067] The relay energy transmission component 10 is an energy relay for wireless energy transmission between the transmitting component 20 and the receiving component 30. The relay energy transmission component 10 can receive the electric energy sent by the transmitting component 20 based on the principle of electromagnetic induction, and transfer the electric energy to the receiving component 30 based on the principle of electromagnetic induction, thereby realizing wireless energy transmission between the transmitting component 20 and the receiving component 30. Figure 2 , Figure 2 A structural schematic diagram of the relay energy transmission component 10 in an embodiment of the present application is shown. The relay energy transmission component 10 includes a core rod 11 and a relay coil 12 arranged in a ring shape relative to the core rod 11. Generally, a first hardware 13 and a second hardware 14 for installation are respectively provided at both ends of the core rod 11. The transmitting component 20 and the receiving component 30 can also be fixedly installed at the hardware 13 at both ends of the core rod 11 respectively; at the same time, the core rod 11 and the relay coil 12 are integrated and insulated, so that the core rod 11 and the relay coil 12 form an integral structure and ensure the insulation of the relay coil 12.

[0068] Exemplarily, the core rod 11 and the relay coil 12 can be integrated and insulated by various insulating materials such as mica, asbestos, rubber, epoxy resin, etc. The relay coil 12 is encapsulated inside the umbrella skirt 15 composed of insulating material, and the core rod 11 is encapsulated inside the sheath 16 composed of insulating material.

[0069] It can be understood that one or more relay coils 12 arranged in a ring shape relative to the core rod 11 can be set, depending on factors such as the distance of wireless energy transmission and the magnetic field strength of the intermediate coil. Technical personnel in this field can set it according to actual needs, and this application does not make specific limitations.

[0070] The transmitting component 20 is connected to the external power source through a wire, so that the transmitting component 20 converts the electric energy of the external power source into magnetic field energy through electromagnetic induction, thereby indirectly transmitting the electric energy of the external power source to the relay coil 12 of the relay transmission component 10. Figure 3 as well as Figure 4 , Figure 3 A schematic diagram of assembling the transmitting assembly 20 in the embodiment of the present application is shown. Figure 4An exploded schematic diagram of the transmitting assembly 20 in the embodiment of the present application is shown. The transmitting assembly 20 includes a first insulating shell 21 and a transmitting coil 22 ( Figure 3 (not shown), the first insulating shell 21 is detachably mounted on the first hardware 13 in an annular shape, and the transmitting coil 22 is fixed in the first insulating shell 21 and arranged in an annular shape relative to the first hardware 13 (i.e., the axis of the core rod 11). After the transmitting coil 22 receives the alternating current from the external power supply, the transmitting coil 22 can generate a changing magnetic field, thereby affecting the relay coil 12 and causing it to generate an induced current.

[0071] In some embodiments of the present application, a through hole is provided in the middle of the first insulating shell 21, so that the first insulating shell 21 is passed through the through hole and is arranged on the first hardware 13, and the transmitting coil 22 inside the first insulating shell 21 is arranged in a ring shape relative to the first hardware 13. Figure 3 as well as Figure 4 A first waterproof connector 29 is provided on the first insulating shell 21 so that the wire connected to the external power supply can be connected to the transmitting coil 22 and / or the first circuit board in the first insulating shell 21 through the waterproof connector.

[0072] In some embodiments of the present application, see Figure 3 as well as Figure 4 The first insulating shell 21 includes a first shell member 211 and a second shell member 212. The first shell member 211 and the second shell member 212 are connected along the axis of the core rod 11 and fixed by bolts, so that the transmitting coil 22 can be installed in the first insulating shell 21 and its insulation is guaranteed.

[0073] It is understandable that the composition or docking method of the first insulating housing 21 is not limited to the following. Figure 3 As shown in the first shell member 211 and the second shell member 212, in some possible embodiments, the first insulating shell 21 can also be formed into a closed insulating shell by a larger number of shell members, or the first shell member 211 and the second shell member 212 can also be formed into a closed insulating shell along the axial direction perpendicular to the core rod 11.

[0074] The receiving component 30 is connected to an external load (such as an online monitoring device) through a wire, so that the external load is powered by the induced current generated by the receiving component 30. Figure 5 as well as Figure 6 , Figure 5 A schematic diagram of assembling the receiving component 30 in the embodiment of the present application is shown. Figure 6 An exploded schematic diagram of a receiving component 30 in an embodiment of the present application is shown. The receiving component 30 includes a second insulating shell 31 and a receiving coil 32 ( Figure 5(not shown), the second insulating shell 31 is detachably mounted on the second hardware 14 in a ring shape, and the receiving coil 32 is fixed in the second insulating shell 31 and arranged in a ring shape relative to the second hardware 14. After the relay coil 12 generates an induced current and a changing magnetic field, the receiving coil 32 can generate an induced current, which can be rectified into a DC power supply by a rectifier circuit to power an external load.

[0075] In some embodiments of the present application, the second insulating shell 31 has a through hole in the middle, so that the second insulating shell 31 is installed on the second hardware 14 through the through hole, and the receiving coil 32 inside the second insulating shell 31 is arranged in a ring shape relative to the second hardware 14. Figure 5 as well as Figure 6 A second waterproof connector 38 is provided on the second insulating shell 31 so that the wire connected to the external load can be connected to the receiving coil 32 and / or the second circuit board in the second insulating shell 31 through the waterproof connector.

[0076] In some embodiments of the present application, see Figure 5 as well as Figure 6 The second insulating shell 31 includes a third shell member 311 and a fourth shell member 312. The third shell member 311 and the fourth shell member 312 are connected along the axial direction of the core rod 11 and fixed by bolts, so that the receiving coil 32 can be installed in the second insulating shell 31 and its insulation is guaranteed.

[0077] It is understandable that the composition or docking method of the second insulating housing 31 is not limited to the following. Figure 5 As shown in the third shell member 311 and the fourth shell member 312, in some possible embodiments, the second insulating shell 31 can also be formed into a closed insulating shell by a larger number of shell members, or the third shell member 311 and the fourth shell member 312 can also be formed into a closed insulating shell along the axial direction perpendicular to the core rod 11.

[0078] In the embodiment of the present application, the present application can fix the transmitting coil 22 in the first insulating shell 21 and arrange it in a ring shape relative to the first hardware 13, and fix the receiving coil 32 in the second insulating shell 31 and arrange it in a ring shape relative to the second hardware 14, by detachably mounting the first insulating shell 21 in a ring shape on the first hardware 13, and detachably mounting the second insulating shell 31 in a ring shape on the second hardware 14. This can not only ensure the wireless transmission of energy between the transmitting coil 22, the relay coil 12 and the receiving coil 32, but also avoid the risk of cracking caused by directly leading out wires from the insulating packaging of the transmitting coil 22 and the receiving coil 32.

[0079] In some embodiments of the present application, see Figure 7 , Figure 7 A cross-sectional schematic diagram of the transmitting component 20 in an embodiment of the present application is shown, wherein a first electromagnetic shielding box 23 made of a conductor is arranged inside the first insulating shell 21; a first circuit board (not shown in the figure) having an inverter circuit is arranged inside the first electromagnetic shielding box 23, and the first circuit board is electrically connected to the transmitting coil 22.

[0080] It should be noted that the inverter circuit can convert direct current into alternating current, so the first circuit board with the inverter circuit can output alternating current and drive the transmitting coil 22 to generate an alternating magnetic field, thereby causing the relay coil 12 to generate an induced current under the action of the alternating magnetic field; in the related art, since the alternating magnetic field generated by the transmitting coil 22 will cause serious electromagnetic interference to the first circuit board with the inverter circuit, it is usually necessary to separate the transmitting coil 22 from the first circuit board with the inverter circuit, which makes the transmitting component 20 unable to be modularly assembled and increases the maintenance and replacement costs of the transmitting component 20.

[0081] In the above embodiment, since the first circuit board with the inverter circuit is arranged in the first electromagnetic shielding box 23 made of a conductor (such as a metal material), even if the first electromagnetic shielding box 23 with the first circuit board arranged inside is arranged in the first insulating shell 21, the first electromagnetic shielding box 23 can also shield the electromagnetic interference of the transmitting coil 22 to the first circuit board, which is equivalent to realizing the modular assembly of the first circuit board with the inverter circuit and the transmitting coil 22 in the first insulating shell 21, thereby reducing the maintenance and replacement costs of the transmitting component 20.

[0082] In some embodiments of the present application, see Figure 7 The first electromagnetic shielding box 23 is arranged in a non-annular shape in the first insulating shell 21. For example, the first electromagnetic shielding box 23 is arranged in a semicircular, quarter-circular, or rectangular shape. Since the first electromagnetic shielding box 23 is not in a circular shape, the first electromagnetic shielding box 23 made of a conductor will not be affected by the transmitting coil 22 to generate an induced current, thereby reducing the influence of the first electromagnetic shielding box 23 made of a conductor on the efficiency of the transmitting coil 22; at the same time, since the first electromagnetic shielding box 23 and the transmitting coil 22 are respectively arranged on the inner wall surfaces opposite to each other of the first insulating shell 21, the first electromagnetic shielding box 23 and the transmitting coil 22 are far away from each other, thereby also weakening the eddy current heating phenomenon generated by the first electromagnetic shielding box 23 under the action of the magnetic field of the transmitting coil 22.

[0083] In some embodiments of the present application, see Figure 7, wherein a first coil fixing ring 24 made of insulating material is also provided inside the first insulating shell 21; the first coil fixing ring 24 divides the internal space of the first insulating shell 21 into a first chamber 201 and a second chamber 202 along the axis of the core rod 11; the transmitting coil 22 is arranged in the first chamber 201, and the first electromagnetic shielding box 23 is arranged in the second chamber 202, so that the transmitting coil 22 and the first electromagnetic shielding box 23 are separated, which is equivalent to further providing an insulating package for the transmitting coil 22. At the same time, the first coil fixing ring 24 can also fix the transmitting coil 22, so as to avoid the modular multi-relay wireless energy transmission system structure from shaking, causing the transmitting coil 22 and the first electromagnetic shielding box 23 to approach each other, and finally causing the first electromagnetic shielding box 23 to generate eddy current heating.

[0084] In some embodiments of the present application, see Figure 7 , wherein the launching assembly 20 also includes a first annular fixing block 25, a first clamping block 27 and at least two first clamping blocks 26; the first annular fixing block 25 is fixed on the first insulating shell 21, the first annular fixing block 25 has a first through hole 251, and the first hardware 13 is passed through the first through hole 251; at least two first clamping blocks 26 are arranged in an annular interval around the first hardware 13, and the first clamping block 27 presses against the first clamping block 26 so that at least two first clamping blocks 26 are filled between the first annular fixing block 25 and the first hardware 13.

[0085] It should be noted that the first clamping block 26 can be made of an elastic material (such as rubber). After the first clamping block 27 is pressed against the first clamping block 26 and filled between the first annular fixing block 25 and the first hardware 13, the first clamping block 26 is deformed and generates elastic force, so that friction is generated between the first clamping block 26 and the first annular fixing block 25, and between the first clamping block 26 and the first hardware 13. The first clamping block 26 is used to indirectly fix the first annular fixing block 25 and the first hardware 13, and finally the first insulating shell 21 is fixed to the first hardware 13 through the first clamping block 26, the first clamping block 27 and the first annular fixing block 25, and the detachable installation between the launching assembly 20 and the first hardware 13 is realized.

[0086] In some embodiments of the present application, the first clamping block 27 can be fixed to the first annular fixing block 25 by bolts, so that the first clamping block 26 is pushed into the annular chamber between the first annular fixing block 25 and the first hardware 13 by the pre-tightening force of the bolts. It can be understood that the first clamping block 27 can also be fixed to the first insulating housing 21 by bolts, and the first clamping block 26 is pushed into the annular chamber between the first annular fixing block 25 and the first hardware 13 by the pre-tightening force of the bolts between the first insulating housing 21 and the first clamping block 27.

[0087] In some embodiments of the present application, see Figure 7 as well as Figure 8 , Figure 8 A schematic diagram of the structure of the first clamping block 26 in the embodiment of the present application is shown, and the inner diameter of the first through hole 251 is along the direction pointing to the relay coil 12 (such as Figure 7 The cross-sectional area of ​​the first clamping block 26 perpendicular to the axis of the first through hole 251 is along the direction pointing to the relay coil 12 (such as Figure 7 The pressing direction of the first pressing block 27 shown in the figure gradually decreases.

[0088] For example, taking the first through hole 251 as a circular hole, the first through hole 251 is a conical hole whose inner diameter gradually decreases along the pressing direction of the first clamping block 27, and the outer wall surface of the first clamping block 26 in contact with the first through hole 251 is a conical arc surface. Therefore, when the first clamping block 27 presses the first clamping block 26 and moves along the pressing direction, at least two first clamping blocks 26 arranged at intervals will move together to clamp the first hardware 13, and finally the launching assembly 20 is fixed on the first hardware 13.

[0089] It is understandable that the implementation of the first through hole 251 and the first clamping block 26 is not limited thereto. For example, the first through hole 251 may also be a square-conical hole, and the outer wall surface of the first clamping block 26 is a slope that matches the square-conical hole.

[0090] In some embodiments of the present application, see Figure 7 as well as Figure 8 , wherein the first clamping block 26 has a plurality of first clamping portions 261 arranged at intervals in the circumferential direction around the first hardware 13, and a first connecting portion 262 connecting adjacent first clamping portions 261 along the outer periphery of the first clamping block 26; wherein, when the first clamping block 27 clamps the first clamping block 26, the ends of adjacent first clamping portions 261 facing away from the first connecting portion 262 close together to reduce the inner diameter of the first clamping block 26 and clamp the first hardware 13.

[0091] It should be noted that since the cross-sectional area of ​​the first clamping block 26 perpendicular to the axial direction of the first through hole 251 gradually decreases along the pressing direction of the first clamping block 27, when the first clamping block 27 presses the first clamping block 26, due to the squeezing of the inner wall of the first through hole 251, the adjacent first clamping parts 261 will close together at the ends away from the first connecting part 262, thereby reducing the inner diameter of the first clamping block 26 and making the multiple first clamping parts 261 clamp the first hardware 13 in a ring shape. That is to say, for the first clamping block 26, the first clamping block 26 can clamp the first hardware 13 in a ring shape under the pressing of the first clamping block 27, so as to realize circumferential multi-point fixation of the first hardware 13, which is beneficial to improve the fixing firmness between the first clamping block 27 and the first hardware 13, and finally make the launching assembly 20 more reliably fixed on the first hardware 13.

[0092] In some embodiments of the present application, the first annular fixing block 25 and the first clamping block 26 are conductive; wherein, the first clamping block 26 is in electrical contact with the first hardware 13, so that the first annular fixing block 25, the first clamping block 26 and the first hardware 13 form an equipotential body, and the first annular fixing block 25 and the first clamping block 26 are located on the side of the transmitting coil 22 away from the relay coil 12.

[0093] It should be noted that, since the first annular fixing block 25 and the first clamping block 26 are conductive, the first clamping block 26 is in electrical contact with the first hardware 13 and forms an equipotential body with the first annular fixing block 25, the first clamping block 26 and the first hardware 13, the first annular fixing block 25 can also improve the voltage distribution of the first hardware 13. At the same time, since the first annular fixing block 25 and the first clamping block 26 are located on the side of the transmitting coil 22 away from the relay coil 12, the conductive first annular fixing block 25 and the first clamping block 26 can be prevented from generating eddy current heating due to the influence of the magnetic field when they are close to the transmitting coil 22.

[0094] In some embodiments of the present application, see Figure 3 as well as Figure 4 The transmitting assembly 20 further includes a first grading ring 28 fixed on the first insulating shell 21; the first grading ring 28 is electrically connected to the first annular fixing block 25, so that the first grading ring 28 and the first hardware 13 form an equipotential body and play a role of a uniform electric field. At the same time, since the first grading ring 28 is located at the periphery of the transmitting coil 22, the magnetic field of the transmitting coil 22 at the periphery is relatively weak, so the first grading ring 28 will not be affected by the magnetic field due to being close to the transmitting coil 22 and generating eddy current heating.

[0095] In some embodiments of the present application, see Fig. 9 , Fig. 9A cross-sectional schematic diagram of the receiving component 30 in an embodiment of the present application is shown, wherein a second electromagnetic shielding box 33 made of a conductor is arranged inside the second insulating shell 31; a second circuit board (not shown in the figure) with a rectifier circuit is arranged inside the second electromagnetic shielding box 33, and the second circuit board is electrically connected to the receiving coil 32.

[0096] It should be noted that the rectifier circuit can convert AC current into DC current, so the second circuit board with the rectifier circuit can output DC current to drive the corresponding load to work; in the related art, since the alternating magnetic field generated by the receiving coil 32 will cause serious electromagnetic interference to the second circuit board with the inverter circuit, it is usually necessary to separate the receiving coil 32 from the second circuit board with the inverter circuit, which makes the receiving component 30 unable to be modularly assembled and increases the maintenance and replacement cost of the receiving component 30.

[0097] In the above embodiment, since the second circuit board with the inverter circuit is arranged in the second electromagnetic shielding box 33 made of a conductor (such as a metal material), even if the second electromagnetic shielding box 33 with the second circuit board arranged inside is arranged in the second insulating shell 31, the second electromagnetic shielding box 33 can also shield the electromagnetic interference of the receiving coil 32 to the second circuit board, which is equivalent to realizing the modular assembly of the second circuit board with the inverter circuit and the receiving coil 32 in the second insulating shell 31, thereby reducing the maintenance and replacement costs of the receiving component 30.

[0098] In some embodiments of the present application, see Fig. 9 The second electromagnetic shielding box 33 is arranged in a non-annular shape in the second insulating shell 31. For example, the second electromagnetic shielding box 33 is arranged in a semicircular, quarter-circular, or rectangular shape. Since the second electromagnetic shielding box 33 is not in a circular shape, the second electromagnetic shielding box 33 made of a conductor will not be affected by the receiving coil 32 to generate an induced current, thereby reducing the influence of the second electromagnetic shielding box 33 made of a conductor on the efficiency of the receiving coil 32; at the same time, since the second electromagnetic shielding box 33 and the receiving coil 32 are respectively arranged on the inner wall surfaces opposite to each other of the second insulating shell 31, the second electromagnetic shielding box 33 and the receiving coil 32 are far away from each other, thereby also weakening the eddy current heating phenomenon generated by the second electromagnetic shielding box 33 under the action of the magnetic field of the receiving coil 32.

[0099] In some embodiments of the present application, see Fig. 9, wherein a second coil fixing ring 34 made of insulating material is also provided inside the second insulating shell 31; the second coil fixing ring 34 divides the internal space of the second insulating shell 31 into a third chamber 301 and a fourth chamber 302 along the axis of the core rod 11; the receiving coil 32 is arranged in the third chamber 301, and the second electromagnetic shielding box 33 is arranged in the fourth chamber 302, so that the receiving coil 32 and the second electromagnetic shielding box 33 are separated, which is equivalent to further providing an insulating package for the receiving coil 32. At the same time, the second coil fixing ring 34 can also fix the receiving coil 32, so as to avoid the modular multi-relay wireless energy transmission system structure causing the receiving coil 32 and the second electromagnetic shielding box 33 to be close to each other due to shaking, thereby causing the second electromagnetic shielding box 33 to generate eddy current heating.

[0100] In some embodiments of the present application, see Fig. 9 , wherein the receiving component 30 also includes a second annular fixing block 35, a second clamping block 37 and at least two second clamping blocks 36; the second annular fixing block 35 is fixed on the second insulating shell 31, the second annular fixing block 35 has a second through hole 351, and the second hardware 14 is passed through the second through hole 351; at least two second clamping blocks 36 are arranged in an annular interval around the second hardware 14, and the second clamping block 37 presses against the second clamping block 36 so that at least two second clamping blocks 36 are filled between the second annular fixing block 35 and the second hardware 14.

[0101] It should be noted that the second clamping block 36 can be made of an elastic material (such as rubber). After the second clamping block 37 presses against the second clamping block 36 and fills the space between the second annular fixing block 35 and the second hardware 14, the second clamping block 36 deforms and generates elastic force, so that friction is generated between the second clamping block 36 and the second annular fixing block 35, and between the second clamping block 36 and the second hardware 14. The second clamping block 36 is used to indirectly fix the second annular fixing block 35 and the second hardware 14, and finally the second insulating shell 31 is fixed to the second hardware 14 through the second clamping block 36, the second clamping block 37 and the second annular fixing block 35, and the detachable installation between the receiving component 30 and the second hardware 14 is realized.

[0102] In some embodiments of the present application, the second clamping block 36 can be clamped on the fitting at one end of the second fitting 14. In some other embodiments of the present application, the second clamping block 36 can be clamped on the insulating packaging layer on the surface of the second fitting 14.

[0103] In some embodiments of the present application, the second clamping block 37 can be fixed to the second annular fixing block 35 by bolts, so that the second clamping block 36 is pressed between the second annular fixing block 35 and the second hardware 14 by the pre-tightening force of the bolts. It can be understood that the second clamping block 37 can also be fixed to the second insulating housing 31 by bolts, and the second clamping block 36 is pressed between the second annular fixing block 35 and the second hardware 14 by the pre-tightening force of the bolts between the second insulating housing 31 and the second clamping block 37.

[0104] In some embodiments of the present application, see Fig. 9 as well as Fig.10 , Fig.10 A schematic diagram of the structure of the second clamping block 36 in the embodiment of the present application is shown, and the inner diameter of the second through hole 351 is along the direction pointing to the relay coil 12 (such as Fig. 9 The cross-sectional area of ​​the second clamping block 36 perpendicular to the axis of the second through hole 351 is along the direction pointing to the relay coil 12 (such as Fig. 9 The pressing direction of the second pressing block 37 shown in the figure gradually decreases.

[0105] For example, taking the second through hole 351 as a circular hole, the second through hole 351 is a conical hole whose inner diameter gradually decreases along the pressing direction of the second clamping block 37, and the outer wall surface of the second clamping block 36 in contact with the second through hole 351 is a conical arc surface. Therefore, when the second clamping block 37 presses the second clamping block 36 and moves along the pressing direction, at least two second clamping blocks 36 arranged at intervals will move together to clamp the second hardware 14, thereby finally achieving the fixation of the receiving component 30 on the second hardware 14.

[0106] It is understandable that the implementation of the second through hole 351 and the second clamping block 36 is not limited thereto. For example, the second through hole 351 may also be a square-conical hole, and the outer wall surface of the second clamping block 36 is a slope that matches the square-conical hole.

[0107] In some embodiments of the present application, see Fig. 9 as well as Fig.10 , wherein the second clamping block 36 has a plurality of second clamping portions 361 arranged at intervals in the circumferential direction around the second hardware 14, and a second connecting portion 362 connecting adjacent second clamping portions 361 along the outer circumference of the second clamping block 36; wherein, when the second pressing block 37 presses the second clamping block 36, the ends of adjacent second clamping portions 361 facing away from the second connecting portion 362 close together to reduce the inner diameter of the second clamping block 36 and clamp the second hardware 14.

[0108] It should be noted that since the cross-sectional area of ​​the second clamping block 36 perpendicular to the axial direction of the second through hole 351 gradually decreases along the pressing direction of the second clamping block 37, when the second clamping block 37 presses the second clamping block 36, due to the squeezing of the inner wall of the second through hole 351, the adjacent second clamping parts 361 will close together at the ends away from the second connecting part 362, thereby reducing the inner diameter of the second clamping block 36 and making the multiple second clamping parts 361 clamp the second hardware 14 in a ring shape. That is to say, for the second clamping block 36, the second clamping block 36 can clamp the second hardware 14 in a ring shape under the pressing of the second clamping block 37, so as to realize circumferential multi-point fixation of the second hardware 14, which is beneficial to improve the fixing firmness between the second clamping block 37 and the second hardware 14, so that the receiving component is more reliably fixed on the second hardware 14.

Under the guidance of the present application, those skilled in the art can also make equivalent modification designs or further, for example, in Figure 7 In the figure, the first pressure-equalizing ring 28 is fixed to the first annular fixing block 25 by an integrated metal support arm. In some possible embodiments, the first pressure-equalizing ring 28 can also be fixed in a ring shape on the outer periphery of the first annular fixing block 25; for example, sealing rings and / or sealing glue treatments are used at each sealing point to further improve the waterproofness of the transmitting component 20 and / or the receiving component 30.
