Description

Technical Field

[0001] This utility model relates to the field of microwave energy transmission technology, specifically to a vacuum packaging structure for a microwave transmission device. Background Technology

[0002] Microwave wireless power transfer technology is a technology that uses microwaves to achieve long-distance, non-contact power transfer. However, it is prone to attenuation and energy loss when used in an atmospheric environment. When large-scale power transfer is required, the use of a guide plate will further increase the loss. Therefore, for short-distance power transmission, wireless power transfer in a vacuum environment is often used to reduce the loss.

[0003] However, existing vacuum environments either use sealant or other materials for comprehensive sealing, which is inconvenient for disassembly and maintenance, or use structures such as snap-on covers for sealing, but the pressure on the sealing surface cannot be adjusted, and the snap-on mechanism is difficult to engage, which is not conducive to operation. Utility Model Content

[0004] Technical objective: To address the shortcomings of existing vacuum structures in microwave transmission devices, this utility model discloses a vacuum packaging structure for microwave transmission devices.

[0005] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution:

[0006] A vacuum encapsulation structure for a microwave transmission device, used to create a vacuum microwave energy transmission environment, includes an encapsulation shell and a cover plate disposed on the encapsulation shell. The encapsulation shell has cable holes for power line harnesses to pass through, and a sealing mechanism is provided at the cable holes for sealing. A sealing ring is provided between the cover plate and the contact surface of the encapsulation shell, and a locking plate is provided on the outer periphery of the cover plate. The locking plate is rotatably engaged with the edge of the cover plate. A latching block is provided on the outer wall of the encapsulation shell to engage with the locking plate. The latching block is slidably connected to the encapsulation shell along a direction perpendicular to the surface of the cover plate, and is moved by a sliding drive mechanism disposed on the encapsulation shell.

[0007] Preferably, the sealing mechanism of this utility model includes a first sealing plate and a second sealing plate respectively disposed at both ends of the cable hole of the encapsulation housing. The first sealing plate and the second sealing plate have the same structure, each including a flange end for connecting to the surface of the encapsulation housing and a sealing end extending into the cable hole. The diameter of the sealing end matches the power line harness, and a sealing collar is provided between the ends of the first sealing plate and the second sealing plate.

[0008] Preferably, the sealing collar of this utility model has an annular groove that matches the sealing end. After the first sealing plate and the second sealing plate are installed, the area on both sides of the annular groove of the sealing collar is squeezed so that the sealing collar is tightly attached to the inner wall of the power line harness and cable hole.

[0009] Preferably, sealant is used to fill the gap between the sealing end and the wall of the cable hole in this invention.

[0010] Preferably, the sliding drive mechanism of this utility model includes a screw shaft that is threadedly engaged with the buckle block. The screw shaft is fixed to the packaging housing by a mounting block that is rotatably connected. The screw shafts connected to the buckles on the same side of the packaging housing are connected by a sprocket structure, and the screw shafts rotate synchronously to drive the buckles to slide.

[0011] Preferably, the cover plate of this utility model is provided with a one-way airtight valve for connecting with a vacuum pump.

[0012] Beneficial effects: The vacuum packaging structure of the microwave transmission device disclosed in this utility model has the following beneficial effects:

[0013] 1. This utility model features a sliding buckle block that moves via a sliding drive mechanism. When closing the device, the buckle plate can be connected to the buckle block first, and then locked by the sliding drive mechanism. This reduces installation difficulty and allows for flexible control and adjustment of the sealing ring's clamping force.

[0014] 2. The sealing mechanism of this utility model radially compresses the sealing ring through the first sealing plate and the second sealing plate, which can simultaneously seal the power harness and the inner wall of the cable viewing hole. At the same time, the sealing will not affect the insulation of the harness surface, and it is easy to disassemble and adjust. Attached Figure Description

[0021] Reference will now be made in detail to embodiments of the present disclosure, one or more of which are set forth herein. Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. Rather, the following description provides convenient illustrations for implementing exemplary embodiments of the present disclosure. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0022] like Figures 1-4 As shown, this utility model discloses a vacuum packaging structure for a microwave transmission device, used to create a vacuum microwave energy transmission environment. It includes a packaging shell 1 and a cover plate 2 on the packaging shell 1. The cover plate 2 has a one-way airtight valve 11 for communicating with a vacuum pump. The packaging shell 1 has cable holes 3 for power line harnesses to pass through, and a sealing mechanism is provided at the cable holes 3 for sealing. A sealing ring is provided between the cover plate 2 and the packaging shell 1. A locking plate 4 is provided on the outer periphery of the cover plate 2, rotating with the edge of the cover plate 2. A latching block 5 is provided on the outer wall of the packaging shell 1 to engage with the latching plate 4. The latching block 5 and the latching plate 4 have mutually engaging contact planes. The latching block 5 is slidably connected to the packaging shell 1 along a direction perpendicular to the surface of the cover plate 2, and is moved by a sliding drive mechanism provided on the packaging shell 1. The latching plate 4 and latching block 5 can be symmetrically arranged along the outer periphery of the packaging shell 1, and can be located on both sides or all four sides of the packaging shell 1. The position of the latching block 5 on each side is adjusted by a separate sliding drive mechanism.

[0023] Specifically, the sliding drive mechanism includes a screw shaft 10 that is threadedly engaged with the latch block 5. The screw shaft 10 is fixed to the packaging housing 1 via a rotatably connected mounting block 12. The ends of the screw shaft 10 connected to the latch blocks 5 on the same side of the packaging housing 1 are connected by a sprocket structure. The screw shaft 10 rotates synchronously to drive the latch blocks 5 to slide. When installing the cover plate and packaging housing 1, the locking plate 4 and the latch block 5 are first fastened together. Then, the sliding drive mechanism drives the latch block 5 to move down. The contact plane of the latch block 5 is located above the contact plane of the locking plate 4. The locking plate 4 is gradually pulled by the force between the contact planes, so that the cover plate 2 and the packaging housing 1 are tightly fitted to achieve a seal. The clamping force can be adjusted according to the moving distance of the latch block 5.

[0024] like Figure 2 As shown, the sealing mechanism of this utility model includes a first sealing plate 6 and a second sealing plate 7 respectively disposed at both ends of the cable hole 3 of the encapsulation housing 1. The first sealing plate 6 and the second sealing plate 7 have the same structure, both including a flange end for connecting with the surface of the encapsulation housing 1 and a sealing end extending into the cable hole. The diameter of the sealing end is matched with the power line harness. A sealing collar 8 is provided between the ends of the first sealing plate 6 and the second sealing plate 7.

[0025] The sealing ring 8 of this utility model has an annular groove 9 that matches the sealing end. After the first sealing plate 6 and the second sealing plate 7 are installed, the areas on both sides of the annular groove of the sealing ring 8 are squeezed to make the sealing ring 8 fit tightly against the inner wall of the power line harness and the cable hole, thereby achieving a seal on the inner and outer contact surfaces. In addition, it is also possible to fill the gap between the sealing end and the wall of the cable hole in this utility model with sealant to further ensure the sealing effect at the cable hole 3. At the same time, the sealant is located on the outer surface of the sealing end and will not come into direct contact with the cable, thus facilitating later maintenance and disassembly.

[0026] In use, the device for microwave energy transmission is installed inside the encapsulated housing. For example, for power transmission, the transmitting device is connected to the power grid, and the receiving device is connected to the power-consuming equipment. The power harness is connected by passing through the cable hole 3. Then, the cover plate 2 is installed and fastened to the buckle block 5 by the locking plate 4. The cable hole 3 is sealed by the sealing mechanism to form a seal. A vacuuming operation is performed by connecting the vacuuming device to the one-way airtight valve 11 to form a vacuum environment inside the encapsulated housing 1. The transmitting device and the receiving device use microwaves to transmit energy and realize power transmission.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
