It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.
[0030] In this article, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also include elements inherent to such process, method, article or equipment. In the absence of further restrictions, the elements defined by the statement "comprising a ..." do not exclude the presence of other identical elements in the process, method, article or equipment comprising the elements. The term "two or more" includes two or more than two cases.
[0031] The present application proposes an energy transmission system 10, which is applied to a floating mooring bollard. The floating mooring bollard is a device that can rise and fall synchronously with the ship as the water level changes. The floating mooring bollard is provided with an energy storage device 4 and a collector. The energy storage device 4 is electrically connected to the collector for powering the collector, and the energy transmission system 10 is electrically connected to the energy storage device 4 for charging the energy storage device 4.
[0032] Please refer to Figure 1 The energy transmission system 10 of the embodiment of the present application includes: a bracket 1, a first coil assembly 2 and a second coil assembly 3.
[0033] The bracket 1 can be formed by welding a stainless steel structure, and after the bracket 1 is welded, the outer surface of the bracket 1 can be galvanized and then painted to ensure that the bracket 1 has outdoor corrosion and moisture resistance and is aesthetically pleasing.
[0034] The bracket 1 is approximately 3 meters to 4 meters long. The bracket 1 is installed in a rectangular slide groove of a cement wall and is fixed to the wall by expansion bolts. The first coil assembly 2 is suitable for being electrically connected to a power supply, and the first coil assembly 2 is installed on the bracket 1. The second coil assembly 3 is suitable for being installed on a floating mooring post, and the second coil assembly 3 is suitable for being electrically connected to an energy storage device 4, wherein the second coil assembly 3 is suitable for moving synchronously with the floating mooring post to contact or separate from the first coil assembly 2. When the second coil assembly 3 contacts the first coil assembly 2, the second coil assembly 3 is coupled with the first coil assembly 2 to charge the energy storage device 4.
[0035] It is understandable that because the floating mooring post rises and falls synchronously with changes in the water level, when the floating mooring post rises and falls synchronously with changes in the water level, the floating mooring post will drive the second coil assembly 3 to move synchronously. When the second coil assembly 3 contacts the first coil assembly 2, the second coil assembly 3 couples with the first coil assembly 2 to charge the energy storage device 4. After the second coil assembly 3 separates from the first coil assembly 2 to a certain distance, the second coil assembly 3 and the first coil assembly 2 cannot couple, and the charging of the energy storage device 4 ends. In this way, the energy storage device 4 can be charged using a wireless charging method that couples the first coil assembly 2 and the second coil assembly 3. That is, the energy storage device 4 does not need to be charged using a wired method, thereby reducing the difficulty of charging the energy storage device 4.
[0036] According to the energy transmission system 10 of the embodiment of the present application, by providing the first coil assembly 2 and the second coil assembly 3, the second coil assembly 3 can move synchronously with the floating bollard to contact the first coil assembly 2, and then the energy storage device 4 is charged through the coupling of the second coil assembly 3 and the first coil assembly 2. In this way, the energy storage device 4 can be charged by a wireless charging method coupled with the first coil assembly 2 and the second coil assembly 3, that is, the energy storage device 4 does not need to adopt a wired charging method, thereby reducing the difficulty of charging the energy storage device 4.
[0037] In some embodiments, the first coil assembly 2 is movably mounted on the bracket 1 along the direction of gravity.
[0038] Therefore, by arranging the first coil assembly 2 to be movably installed on the bracket 1 along the direction of gravity, when the second coil assembly 3 moves synchronously with the floating bollard and contacts the first coil assembly 2, the first coil assembly 2 can move up and down synchronously along the direction of gravity under the drive of the second coil assembly 3, thereby avoiding interference of the first coil assembly 2 with the movement of the second coil.
[0039] At the same time, the first coil assembly 2 and the second coil assembly 3 can move synchronously to improve the stability of the first coil assembly 2 and the second coil assembly 3 during dynamic movement, thereby realizing dynamic energy transmission between the first coil assembly 2 and the second coil assembly 3, and ensuring the energy transmission stability between the first coil assembly 2 and the second coil assembly 3, which is conducive to improving the energy transmission efficiency.
[0040] The first coil assembly 2 can move relative to the bracket 1 in a sliding, rolling, or translational manner, which is not limited here.
[0041] In some embodiments, one of the bracket 1 and the first coil assembly 2 is provided with a slide rail 11 and the other is provided with a pulley 201 , and the pulley 201 is in sliding engagement with the slide rail 11 .
[0042] For example, the bracket 1 is provided with a pulley 201, and the first coil assembly 2 is provided with a slide rail 11; or Figure 1 As shown, the bracket 1 is provided with a slide rail 11, and the first coil assembly 2 is provided with a pulley 201, and the pulley 201 is in sliding engagement with the slide rail 11. Thus, by providing the pulley 201 and the slide rail 11, the first coil assembly 2 is in sliding engagement with the bracket 1, thereby improving the motion stability of the first coil assembly 2 relative to the bracket 1.
[0043] For example, the slide rail 11 is arranged on the bracket 1, and there are two slide rails 11, and the two slide rails 11 are arranged spaced apart. Pullies 201 are provided on the opposite sides of the first coil assembly 2, and the pulleys 201 on both sides of the first coil assembly 2 respectively correspond to and slide with the corresponding slide rails 11.
[0044] As a result, the first coil assembly 2 and the bracket 1 can realize the sliding of the first coil assembly 2 relative to the bracket 1 through the cooperation of two sets of slide rails 11 and pulleys 201, thereby facilitating the improvement of the movement stability of the first coil assembly 2 relative to the bracket 1, and the slide rails 11 can play a certain guiding role, thereby ensuring the stability of the movement direction of the first coil assembly 2.
[0045] Among them, the slide rail 11 can be formed by welding channel steel, and the pulley 201 adopts a stainless steel one-piece customized wheel with a bearing, which can withstand gravity and a certain overturning force. The stainless steel wheel has high wear resistance, good weather resistance, simple maintenance, and low requirements for the straightness of the slide rail 11.
[0046] In some embodiments, as Figure 2 and Figure 3 As shown, the first coil assembly 2 includes a primary coil 21 and a primary bracket 22 . The primary bracket 22 is slidably matched with the bracket 1 , and the primary coil 21 is installed on the primary bracket 22 .
[0047] Therefore, by setting the primary bracket 22, the primary coil 21 is fixed by the primary bracket 22, thereby enhancing the structural stability of the primary coil 21. After the primary coil 21 is fixed to the primary bracket 22, the primary bracket 22 slides with the bracket 1. For example, the pulley 201 can be set on the primary bracket 22, and the slide rail 11 is set on the bracket 1. The pulley 201 slides with the slide rail 11, so that the primary bracket 22 drives the primary coil 21 to slide relative to the bracket 1.
[0048] Among them, the primary side bracket 22 can be welded into a stainless steel structure, and after the primary side bracket 22 is welded into shape, the outer surface of the primary side bracket 22 can be galvanized and then painted to ensure that the primary side bracket 22 has outdoor corrosion and moisture-proof performance and is also beautiful.
[0049] In some implementations, such as Figure 4As shown, the housing of the primary coil 21 may include: a coil housing side wall 211, a first sealing ring 212, a coil housing bottom plate 213, a flange gasket 214, a coil bottom plate 215, a coil upper cover 216, a PCB box body 217, a connector 218, and a PCB box upper cover 219, wherein the connector 218 may be a YMA waterproof connector, the first sealing ring 212 is an O-ring, and a screw plus O-ring sealing structure is used between the coil housing side wall 211 and the coil housing bottom plate 213, the coil upper cover 216 and the coil housing side wall 211, and the PCB housing 412 and the coil upper cover 216 to ensure waterproof performance in harsh environments. This design, coupled with the excellent performance of each material, ensures the outdoor performance of the primary coil 21.
[0050] In some implementations, the coil housing side wall 211 and the coil housing bottom plate 213 of the primary coil 21 are machined from high-performance aluminum alloy and polytetrafluoroethylene, and the various components are fastened with blind hole threads and an O-ring self-sealing structure. The connector 218 uses a marine YMA series waterproof aviation plug.
[0051] In this way, the primary coil 21 can be made of high-quality raw materials, a reliable sealing structure, and connector 218, ensuring the stability and reliability of the primary coil 21 outdoors. The aluminum alloy can be 6061 aluminum alloy, which has excellent corrosion resistance and toughness, is not easily deformed after processing, is easy to color film, and has excellent heat dissipation. The energy transfer surface and coil disk of the primary coil 21 are made of polytetrafluoroethylene, which has excellent comprehensive mechanical properties. Polytetrafluoroethylene has excellent insulation properties and excellent chemical stability, and can be used for long periods of time in high-temperature environments, which is very suitable for the operating environment of the device.
[0052] The first sealing ring 212 is made of nitrile rubber, and the static service life of nitrile rubber can be as long as about 10 years, so that the first sealing ring 212 meets the design requirements.
[0053] In some embodiments, the second coil assembly 3 includes a secondary coil 31 and a secondary bracket 32. The secondary bracket 32 is suitable for being mounted on a floating bollard, and the secondary coil 31 is mounted on the secondary bracket 32. Thus, by providing the secondary bracket 32, the secondary coil 31 is fixed by the secondary bracket 32, thereby enhancing the structural stability of the secondary coil 31.
[0054] Among them, the secondary side bracket 32 can be welded into a stainless steel structure, and after the secondary side bracket 32 is welded into shape, the outer surface of the secondary side bracket 32 can be galvanized and then painted to ensure that the secondary side bracket 32 has outdoor corrosion and moisture-proof performance and is also beautiful.
[0055] It should be noted that the specific structure of the shell of the secondary coil 31 is basically the same as the structure of the shell of the primary coil 21 in the above embodiment, and can achieve the same technical effect, which will not be described in detail here.
[0056] In some embodiments, the primary coil 21 and the secondary coil 31 are designed with a circular symmetrical structure. Structurally, the energy transmission distance between the primary coil 21 and the secondary coil 31 is constant, the transmission efficiency is high, the magnetic leakage is small, and the processing and installation are simple and the maintenance is convenient.
[0057] In some embodiments, as Figure 2 and Figure 3 As shown, a buffer structure 5 is provided on the side of the first coil assembly 2 facing the second coil assembly 3; and / or as shown Figure 5 and Figure 6 As shown, a buffer structure 5 is provided on the side of the second coil assembly 3 facing the first coil assembly 2 .
[0058] For example, a buffer structure 5 is provided on the side of the first coil assembly 2 facing the second coil assembly 3. The buffer structure 5 can be a polyurethane block. In this way, when the second coil assembly 3 moves with the floating mooring column until it contacts the first coil assembly 2, the buffer structure 5 can act as a buffer between the first coil assembly 2 and the second coil assembly 3 to avoid rigid collision between the first coil assembly 2 and the second coil assembly 3.
[0059] And / or a buffer structure 5 is provided on the side of the second coil assembly 3 facing the first coil assembly 2. The buffer structure 5 can be a polyurethane block. A support column 51 is provided on the second coil assembly 3. The support column 51 is a rigid structure. The polyurethane block is installed on the support column 51. In this way, when the second coil assembly 3 moves with the floating mooring column to contact the first coil assembly 2, the buffer structure 5 can act as a buffer between the first coil assembly 2 and the second coil assembly 3 to avoid rigid collision between the first coil assembly 2 and the second coil assembly 3.
[0060] In some embodiments, please refer to Figure 7 The energy storage device 4 includes a shell 41, a battery module and a circuit board 42. The battery module and the circuit board 42 are both installed in the shell 41, so that the shell 41 can provide waterproof and protective effects on the battery module and the circuit board 42. A detection module is provided on the circuit board 42, and the detection module is used to detect the charging voltage and / or charging current of the battery module.
[0061] Therefore, the charging voltage and / or charging current of the battery module can be detected by the detection module, so as to detect the charging state of the battery module.
[0062] Among them, the outer shell 41 includes an upper cover 411 and a shell 412. The upper cover 411 and the shell 412 are sealed and connected by a second sealing ring 413 to form the outer shell 41, thereby ensuring the sealing performance of the outer shell 41. The second sealing ring 413 can be an O-ring constructed of nitrile rubber, so that the second sealing ring 413 has a longer service life, thereby meeting the design requirements of the second sealing ring 413.
[0063] In some embodiments, the energy storage device 4 is mounted on a floating bollard via a fixing plate 45 to enhance the structural stability of the energy storage device 4 .
[0064] In some embodiments, a communication module is further provided on the circuit board 42 . The communication module is electrically connected to the detection module, and the communication module is suitable for communication connection with a communication device.
[0065] Thus, the detected information can be transmitted to the communication device through the communication module in the form of signal transmission, so as to facilitate checking the charging status of the battery module.
[0066] For example, the communication equipment can be set up in the monitoring room on the ground. The detection module can detect the charging voltage and charging current of the battery module once every minute. The communication module then transmits the detection information to the communication equipment in the monitoring room on the ground, so that the staff can observe the charging status of the battery module at any time in the monitoring room.
[0067] In some embodiments, housing 41 is provided with a circuit connector 43, which is electrically connected to the battery module and is also suitable for electrically connecting to a collector. Circuit connector 43 may be a YMA connector, so that the wires connecting the battery module and the collector can be led out through circuit connector 43. Since circuit connector 43 has good waterproof properties, it enhances the waterproof effect of housing 41.
[0068] In some embodiments, the housing 41 is provided with a radio frequency converter 44, which is electrically connected to the communication module and is used to transmit signals. The second coil assembly 3 may be provided with a communication antenna 33, which may be led out through the radio frequency converter 44 to transmit or receive signals. In particular, the radio frequency converter 44 may be a waterproof converter to enhance the waterproof effect of the radio frequency converter 44, and the radio frequency converter 44 facilitates increasing the wireless communication distance of the communication antenna 33. For example, in an unobstructed environment, the wireless communication distance may reach 10 km, and in the presence of obstacles, the communication distance may reach 300-700 meters.
