Description

Technical Field

[0001] This application relates to the field of communication equipment, and in particular to a broadband feed. Background Technology

[0002] Currently, broadband feeders are widely used in the communications field. Broadband feeders are usually installed in open outdoor locations to transmit wireless signals.

[0003] One type of related technology is a broadband feed source, see reference Figure 1 The broadband feed includes a cylindrical reflector cavity 2, a reflector plate 3, and a radiating element 4. The upper surface of the reflector plate 3 is attached to the bottom end of the cylindrical reflector cavity 2, and the reflector plate 3 and the cylindrical reflector cavity 2 are welded together. The radiating element 4 is disposed inside the cylindrical reflector cavity 2 and is fixedly connected to the reflector plate 3. During operation, the radiating element 4 emits radio signals, and the reflector plate 3 and the cylindrical reflector cavity 2 together reflect the radio signals.

[0004] Regarding the aforementioned technologies, the inventors believe that although the reflective base plate and the cylindrical reflective cavity in the related technologies eliminate gaps through welding and achieve the reflection of radio signals, after rainfall, rainwater will accumulate in the reflective base plate and the cylindrical reflective cavity, which not only affects the reflection effect of radio signals, but also easily leads to water damage to the radiating oscillator. Summary of the Invention

[0005] In related technologies, after rainfall, rainwater accumulates in the reflective base plate and cylindrical reflective cavity of broadband feeds, which not only affects the reflection of radio signals but also easily leads to water damage to the radiating oscillator. To improve this defect, this application provides a broadband feed.

[0006] This application provides a broadband feed source, which is derived using the following technical solution:

[0007] A broadband feed includes a support, a cylindrical reflector cavity, a reflector base plate, and a radiating element. The reflector base plate is fixedly connected to the support, the cylindrical reflector cavity is slidably mounted on the support, and the radiating element is fixedly connected to the inner wall of the cylindrical reflector cavity. An annular groove is formed on the side of the reflector base plate near the cylindrical reflector cavity, and one end of the cylindrical reflector cavity is inserted into the annular groove. The reflector base plate and the cylindrical reflector cavity work together to reflect the signal emitted by the radiating element.

[0008] Through the above technical solution, this application adopts a separate design for the cylindrical reflective cavity and the reflective base plate. The cylindrical reflective cavity can be integrated with the reflective base plate after being inserted into the annular groove, and they can jointly reflect radio signals. Alternatively, it can be separated from the reflective base plate by sliding on the support. The radiating oscillator is fixedly connected to the cylindrical reflective cavity, and when the cylindrical reflective cavity is separated from the reflective base plate, the radiating oscillator will also move away from the reflective base plate.

[0009] During rainfall, rainwater gradually accumulates inside the cylindrical reflector cavity. After the rainfall ends, the operator moves the cylindrical reflector cavity until it is completely separated from the reflector plate. At this point, the rainwater that had accumulated inside the cylindrical reflector cavity flows away along the gap between the cylindrical reflector cavity and the reflector plate, thus achieving rainwater drainage. After the reflector plate and the cylindrical reflector cavity are completely dry, the operator re-inserts the cylindrical reflector cavity into the annular groove, after which the reflector plate and the cylindrical reflector cavity can continue to reflect the signal emitted by the radiating oscillator. The broadband feed of this application can drain the accumulated water inside the cylindrical reflector cavity through manual operation, shortening the time required for the cylindrical reflector cavity and the reflector plate to dry, reducing the impact of water accumulation on the reflection effect, and reducing the possibility of damage to the broadband feed after prolonged immersion in water.

[0010] Preferably, the bottom of the annular groove is provided with a drainage groove that extends through the thickness direction of the reflective base plate.

[0011] With the above technical solution, after the cylindrical reflective cavity separates from the reflective base plate, some of the water accumulated in the cylindrical reflective cavity enters the annular groove and then leaves the annular groove through the drainage groove. The drainage groove can reduce the residual water in the annular groove and improve the drainage effect.

[0012] Preferably, a funnel and a conduit are fixedly provided on the side of the reflective base plate away from the cylindrical reflective cavity, and the funnel is used to transport the water discharged from the drainage trough into the conduit.

[0013] In practical applications of broadband feedhorns, power cables and electronic devices are typically installed below the reflector plate. Water discharged from the drainage trough may cause these cables and devices to become damp. However, in this application's solution, after the water leaves the drainage trough, a funnel collects the water and directs it into a conduit.

[0014] As the water falls, the funnel and conduit work together to isolate the water. Therefore, as long as the power cables and electronic equipment are within the height range between the top of the funnel and the bottom of the conduit, the possibility of the power cables and electronic equipment coming into direct contact with the falling water can be reduced, thus lowering the risk of water ingress and moisture damage to the power cables and electronic equipment.

[0015] Preferably, the broadband feed further includes a drying assembly, which includes a heating wire, a housing, a rain shield, and a fan. The housing is fixedly connected to the side of the reflector base plate away from the cylindrical reflector cavity. The fan is fixedly connected to the housing. The heating wire is fixedly connected to the housing. The fan is used to supply air into the housing. The housing is fixedly connected to the conduit via a branch pipe. The branch pipe communicates with the conduit. The rain shield is used to prevent water from entering the housing from the conduit.

[0016] With the above technical solution, after the cylindrical reflective cavity separates from the reflective base plate, the heating wire and fan are activated. The fan supplies air into the box, while the heating wire heats the air inside the box. Driven by the fan, the hot air generated inside the box continuously enters the duct through the branch pipe. Inside the duct, the hot air rises spontaneously, forming an upward-flowing hot airflow. The hot airflow passes sequentially through the duct, funnel, and drainage trough, drying the inner wall of the cylindrical reflective cavity. Simultaneously, the heat emitted by the box itself also dries the reflective base plate, thus shortening the time required for the cylindrical reflective cavity and reflective base plate to dry completely.

[0017] Preferably, a rubber hose is fixedly connected to the end of the conduit away from the funnel, and one end of the rubber hose is connected to the end of the conduit away from the funnel.

[0018] Through the above technical solution, the rubber hose is deformable. By adjusting the position of the rubber hose, the water discharged from the conduit can flow along the rubber hose to a position farther away from the reflector plate, reducing the possibility of water ingress and moisture damage to the power cables and electronic equipment under the reflector plate. In addition, after the fan and heating wire are started, the operator can reduce the loss of hot airflow by tightening the rubber hose.

[0019] Preferably, the branch pipe is inclined from top to bottom along the direction of the box body toward the conduit.

[0020] With the above technical solution, after setting the tilt direction of the branch pipe in the above manner, the water splashed into the branch pipe can automatically flow back into the conduit, reducing the possibility of water entering the box and helping to ensure the normal operation of the heating wire.

[0021] Preferably, the rainproof component includes steel wool, which is fixedly connected inside the branch pipe.

[0022] Through the above technical solution, when water falls along the conduit, the steel wool can play a certain role in blocking the water splashing into the branch pipe, reducing the possibility of water entering the box.

[0023] While the steel wool obstructs the flow of hot air through the branch pipe, it cannot completely block it, allowing some hot air to still pass through and enter the duct. Furthermore, steel wool, being a metallic material, is a good conductor of heat. When heated by the hot air, the steel wool transfers its heat to the surrounding air, creating a new flow of hot air on the side of the branch pipe closer to the duct, thus reducing its impact on the flow rate of the hot air.

[0024] Preferably, at least two sliders are fixedly connected to the outer wall of the cylindrical reflective cavity, and at least two sliding columns are fixedly connected to the bracket. One of the sliding columns passes through a slider along the axial direction of the cylindrical reflective cavity, and the sliding column and the slider slide in a sliding engagement.

[0025] Through the above technical solution, when the cylindrical reflective cavity or slider is subjected to a force along the axis of the sliding column, the slider and the sliding column slide relative to each other, thereby realizing the adjustment of the position of the cylindrical reflective cavity.

[0026] Preferably, the broadband feed also includes a lifting assembly, which includes a pulley and a traction rope. The pulley is rotatably connected to the bracket, and one end of the traction rope is fixedly connected to the slider. The traction rope is wound around the pulley.

[0027] With the above technical solution, when it is necessary to lift the cylindrical reflector cavity, the operator pulls the traction rope. The traction rope changes its direction of movement under the action of the pulley, which can drive the slider to slide upward along the sliding column, thereby realizing the lifting of the cylindrical reflector cavity.

[0028] Preferably, the end of the traction rope away from the slider is fixedly connected to a positioning screw, and a positioning sleeve is fixedly connected to the bracket. The inner wall of the positioning sleeve is threaded, and the positioning screw is threadedly connected to the positioning sleeve.

[0029] With the above technical solution, after the operator raises the cylindrical reflective cavity by pulling the traction rope, the operator can screw the positioning screw into the positioning sleeve to fix the traction rope and the cylindrical reflective cavity.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. When water accumulates in the cylindrical reflector cavity of the broadband feed of this application, the operator can directly lift the cylindrical reflector cavity to separate it from the reflector base plate, thereby draining the water and shortening the time required for the cylindrical reflector cavity and reflector base plate to dry. This reduces the impact of water accumulation on the reflection effect and also reduces the possibility of damage to the broadband feed after prolonged immersion in water.

[0032] 2. This application uses a conduit to isolate accumulated water falling from the drainage trough, reducing the risk of water ingress and moisture damage to power cables and electronic equipment beneath the reflector plate. Furthermore, the drying assembly and branch pipes allow heat radiating from the drying assembly to dry the reflector plate. The hot airflow generated by the drying assembly enters the conduit through the branch pipe and then passes through the conduit and drainage trough in sequence, achieving the drying of the cylindrical reflector cavity and shortening the time required for complete drying of the cylindrical reflector cavity and reflector plate.

[0039] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0040] This application discloses a broadband feed source. (Refer to...) Figure 2 and Figure 3 The broadband feed includes a support 1, a cylindrical reflector 2, a reflector base plate 3, a radiating element 4, a drying assembly 5, and a lifting assembly 6. The cylindrical reflector 2 is vertically slidably mounted on the support 1. The reflector base plate 3 is horizontally positioned below the cylindrical reflector 2 and fixedly connected to the support 1. The radiating element 4 is fixedly connected to the inner wall of the cylindrical reflector 2. An annular groove 16 is formed at the top of the reflector base plate 3, and the bottom of the cylindrical reflector 2 is inserted into the annular groove 16.

[0041] When the broadband feed operates normally in dry weather, the cylindrical reflector 2 and the reflector plate 3 together reflect the radio signals emitted by the radiating element 4. During rainfall, rainwater falls into the cylindrical reflector 2, forming water accumulation. After the rain, the operator uses the lifting assembly 6 to lift the cylindrical reflector 2, releasing the accumulated water. Then, the drying assembly 5 dries the reflector plate 3 and the cylindrical reflector 2.

[0042] Reference Figure 2 Two sliders 7 are fixedly connected to the outer wall of the cylindrical reflective cavity 2, and the two sliders 7 are arranged opposite each other radially along the cylindrical reflective cavity 2. Two sliding columns 8 are fixedly connected to the bracket 1, and one sliding column 8 passes through one slider 7. The sliding column 8 and the slider 7 slide and engage vertically. The lifting assembly 6 includes a pulley 61 and a traction rope 62. The pulley 61 is rotatably connected to the bracket 1. One end of the traction rope 62 is fixedly connected to one slider 7, and the other end of the traction rope 62 is wound around the pulley 61 and fixedly connected to a positioning screw 9 at the end. A positioning sleeve 10 is fixedly connected to the bracket 1. The inner wall of the positioning sleeve 10 is provided with threads that match the positioning screw 9. The positioning screw 9 is threadedly connected to the positioning sleeve 10.

[0043] When it is necessary to lift the cylindrical reflector cavity 2, the operator pulls the end of the traction rope 62 away from the slider 7. The traction rope 62 pulls the slider 7 through the pulley 61, and the slider 7 and the cylindrical reflector cavity 2 rise under the action of traction force. After that, the operator screws the positioning screw 9 into the positioning sleeve 10, so that the positioning screw 9 and the positioning sleeve 10 are threaded together, thus completing the fixation of the position of the cylindrical reflector cavity 2.

[0044] Reference Figure 3 and Figure 4 The bottom of the annular groove 16 is vertically oriented with four drainage channels 11, which are evenly spaced in pairs along the circumference of the annular groove 16. Four funnels 12 and four conduits 13 are fixedly mounted on the bottom of the reflective base plate 3. One funnel 12 is positioned directly below one drainage channel 11, and one conduit 13 is positioned directly below one funnel 12. The larger diameter end of the funnel 12 faces the drainage channel 11, and the smaller diameter end of the funnel 12 is connected to the conduit 13. A rubber hose 14 is fixedly connected to the end of the conduit 13 furthest from the funnel 12.

[0045] Once the cylindrical reflective cavity 2 rises to its complete separation from the reflective base plate 3, the accumulated water is released. A portion of the water enters the annular groove 16, and the drainage trough 11 discharges the water from the annular groove 16, reducing residual water. After passing through the annular groove 16, the water is collected by the funnel 12, then flows sequentially through the conduit 13 and the rubber hose 14, finally draining away from the port of the rubber hose 14. The funnel 12 and conduit 13 isolate the falling water, while the rubber hose 14 further guides the water away from the reflective base plate 3, reducing the possibility of water ingress and moisture damage to electronic equipment and power cables located below the reflective base plate 3.

[0046] Reference Figure 3 and Figure 4 The drying assembly 5 includes a heating wire 51, a housing 52, a rain shield, and a fan 54. The housing 52 is fixedly connected to the bottom end of the reflective base plate 3, the fan 54 is fixedly connected to the bottom end of the housing 52, and the heating wire 51 is fixedly connected inside the housing 52. Each of the four sides of the housing 52 is connected to the conduit 13 via a branch pipe 15. One end of the branch pipe 15 is fixedly connected to the conduit 13, and the other end is fixedly connected to the housing 52. The branch pipe 15 slopes downwards along the direction from top to bottom towards the conduit 13. The rain shield is made of steel wool 53, which is fixedly connected to the inner wall of the branch pipe 15.

[0047] When the water falls along the conduit 13, the steel wool 53 blocks the water that splashes into the branch pipe 15. At the same time, the inclined branch pipe 15 allows the water entering the branch pipe 15 to flow back into the conduit 13, thereby reducing the possibility of water entering the box 52 and helping to ensure the normal operation of the heating wire 51.

[0048] When drying the reflective base plate 3 and the cylindrical reflective cavity 2 is required, the operator tightens the rubber hose 14, and then the blower 54 blows air into the box 52. The heating wire 51 heats the air inside the box 52, and the hot air forms a hot airflow under the action of the blower. After the hot airflow enters the branch pipe 15, part of it passes through the steel wool 53, while the other part is blocked by the steel wool 53. While blocking the hot airflow, the temperature of the steel wool 53 gradually rises until it is the same as the temperature of the hot airflow. Thereafter, the steel wool 53 heats the air inside the branch pipe 15 near the conduit 13. The heating effect of the steel wool 53 generates a new hot airflow, thereby compensating for the flow rate of the hot airflow entering the conduit 13 and reducing the impact of the steel wool 53's obstruction on the flow rate of the hot airflow.

[0049] After entering the duct 13, the hot air rises along the duct 13, passing sequentially through the duct 13, funnel 12, and drain trough 11, drying the cylindrical reflector cavity 2. Simultaneously, while the heating wire 51 heats up, the housing 52 transfers some heat to the reflector base plate 3, drying it as well. By drying the reflector base plate 3 and the cylindrical reflector cavity 2, the drying assembly 5 shortens the time required for complete drying of both, helping the broadband feed to return to normal operation as soon as possible.

[0050] The implementation principle of a broadband feed in this application embodiment is as follows: In rainless weather, the radio signal emitted by the radiating element 4 is reflected by both the reflective base plate 3 and the cylindrical reflective cavity 2. During rainy weather, water gradually accumulates inside the cylindrical reflective cavity 2. After the rain stops, the operator lifts both the cylindrical reflective cavity 2 and the radiating element 4 using the lifting assembly 6, releasing the accumulated water. After releasing the water, the drying assembly 5 dries the reflective base plate 3 and the cylindrical reflective cavity 2 until the water on the side of the reflective base plate 3 and the cylindrical reflective cavity 2 facing the radiating element 4 completely disappears. Then, the operator re-inserts the cylindrical reflective cavity 2 into the annular groove 16, and the cylindrical reflective cavity 2 and the reflective base plate 3 continue to jointly reflect the radio signal emitted by the radiating element 4.

[0051] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
