Description

Technical Field

[0001] The present invention relates to the technical field of repeaters, and specifically to a repeater and a method for using a repeater based on an underground operation network. Background Art

[0002] Due to the relatively high frequency of 5G signals, the diffraction ability of radio waves is weaker. When the 5G macro base station signals deployed in the high-frequency band pass through walls indoors, they will also face a large link loss problem, and the indoor deep coverage ability is limited. Because the 5G network uses millimeter-wave technology, it is an electromagnetic wave with weak penetration ability and rapid attenuation, which determines its weak anti-interference ability. Coupled with the poor signal penetration of 5G, the signal coverage range of an ordinary 5G base station is generally only more than 200 meters. Therefore, repeaters are needed to make up for the insufficient 5G signal coverage, expand the coverage range of the base station, fill in the coverage blind areas, reduce the cost of network coverage, and promote the development of 5G.

[0003] However, the signal transmission of current repeaters is easily affected by the geographical environment. In particular, for repeaters in underground operation networks, they not only need to overcome extreme terrains such as undulating mountains and fast-flowing hydropower stations, but also need to avoid the interference of groundwater vapor and dust. These factors will not only affect the performance of the equipment, but also affect its working stability. Using it in such a humid underground environment for a long time is likely to cause the modules inside the repeater to be corroded and damaged, thus affecting the 5G network signal and development. Summary of the Invention

[0004] The purpose of the present invention is to provide a repeater and a method for using a repeater based on an underground operation network to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A repeater, comprising: a placement box, on which an upper cover is rotatably provided, and a placement table is further provided inside the placement box. The placement table is used to place the repeater body, and the placement table is connected to the upper cover through a lifting component. When the upper cover deflects relative to the placement box, the lifting component can drive the placement table to lift or sink along the longitudinal direction of the placement box, so that the placement table can drive the repeater body to lift out or sink into the placement box, thus facilitating the detection personnel to detect or store the repeater; A sealing strip and a locking component are further provided on the placement box. The locking component can lock the position of the upper cover, so that the upper cover cannot rotate relative to the placement box. When the locking component acts, the locking component can cooperate with a pressing component provided on the placement box to press the sealing strip, thereby increasing the overall sealing performance of the placement box.

[0006] The repeater as described above: The lifting assembly includes a placement table slidably disposed in the placement box. Four sets of socket cylinders are provided on the placement table. The socket cylinders are evenly distributed around the placement table, and the socket cylinders are connected to the placement box through a driving structure and a guiding structure.

[0007] The repeater as described above: The driving structure includes mounting members fixedly provided in the placement box. Two sets of mounting members are arranged along the length direction of the placement box. Rotating rods are rotatably mounted on both sets of mounting members. A socket cylinder is sleeved on the rotating rod. Synapses are formed on the inner wall of the socket cylinder. The synapses are slidably disposed in fitting grooves opened on the outer wall of the rotating rod. A first spring is also sleeved on the rotating rod. One end of the first spring abuts against the mounting member, and the other end abuts against the placement table.

[0008] The repeater as described above: The fitting groove includes a rotating groove opened on the rotating rod. The travel end of the rotating groove facing the bottom of the placement box is connected to a horizontal groove.

[0009] The repeater as described above: The guiding structure includes guiding rods fixedly provided in the placement box. Two sets of guiding rods are arranged along the length direction of the placement box. The first springs are provided on both sets of guiding rods. One end of the first spring abuts against the placement table, and the other end abuts against a stop piece formed on the guiding rod.

[0010] The repeater as described above: The rotating rod is connected to the upper cover through a triggering assembly. The triggering assembly includes a moving structure and a linkage structure. The moving structure includes an outer attachment box fixedly provided on the placement box. A plug socket cylinder is fixedly provided on the outer attachment box. The rotating shaft of the upper cover is rotatably mounted in the plug socket cylinder. A moving sleeve is sleeved on the rotating shaft. Two sets of moving sleeves are symmetrically arranged along the length direction of the rotating shaft. Protrusions are provided on the inner wall of each set of moving sleeves. The protrusions are slidably disposed in spiral grooves opened on the rotating shaft.

[0011] The repeater as described above: The linkage structure includes a gear coaxially and fixedly provided with the rotating rod. The gear meshes with a toothed plate slidably disposed in the placement box. A connecting rod is fixedly provided on the toothed plate. The connecting rod penetrates through the placement box and is disposed in the outer attachment box. The end of the connecting rod away from the toothed plate is fixedly connected to the moving sleeve.

[0012] Repeater as described above: The locking assembly includes a latch slidably disposed on the placement box. There are two groups of latches symmetrically arranged along the length direction of the placement box. Each group of latches is connected to a slide bar fixedly disposed on the placement box. There are two groups of slide bars symmetrically arranged along the length direction of the latch. A second spring is slidably disposed on each group of slide bars. One end of the second spring abuts against the latch, and the other end abuts against the end of the slide bar. And a protrusion is fixedly disposed on each latch.

[0013] Repeater as described above: The pressing assembly includes a lifting ring. The lifting ring and the sealing strip are both slidably disposed in a placement cavity formed on the placement box. And a lifting plate is fixedly disposed on the lifting ring. There are two groups of lifting plates symmetrically arranged along the length direction of the placement box. An inclined groove is formed on each group of lifting plates. The protrusion is slidably disposed in the inclined groove.

[0014] A usage method based on an in-ground operation network repeater is also proposed. Using a repeater as described above, it includes the following steps: Step 1: Open the upper cover to the maximum extent. Then place the repeater body on the placement table. At this time, the repeater body protrudes from the placement box. Then close the upper cover. Step 2: During the closing process, the rotating shaft of the upper cover can drive the two moving sleeves to move away from each other, thereby driving the toothed plate and the gear into an engaged transmission state, so that the rotating rod rotates continuously in the same direction. Step 3: When the rotating rod rotates, under the cooperation of the socket cylinder and the fitting groove, the placement table drives the repeater body to descend, and then to the lowest descending height. Step 4: When the placement table descends to the lowest height, the upper cover continues to rotate and the rotating rod continues to rotate. At this time, the height position of the placement table remains unchanged. The upper cover contacts the locking assembly, forcing the latch to retract. After the upper cover is completely closed, during the reset process of the latch, the pressing assembly can press the sealing strip, so that the sealing strip protrudes outwards, thereby increasing the connection sealing performance between the upper cover and the extension frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are: Place the repeater body in a placement box with high sealing performance, corrosion resistance, low water absorption and high moisture resistance. The placement box can protect the repeater body, reducing the contact between water vapor and other corrosive substances and the repeater body. Meanwhile, by setting up the lifting component and the triggering component, the position of the repeater body is restricted by the placing table, so that the repeater body cannot move relative to the placing table easily. During the process of opening or closing the upper cover, the triggering component cooperates with the lifting component to control the placing table to drive the repeater body to lift along the longitudinal direction of the placement box. When the upper cover is fully opened, the placing table can make the repeater body protrude from the placement box, exposing the entire repeater body outside the placement box, so that the inspection personnel can disassemble, install or inspect the repeater body in a relatively bright environment, thus providing convenience for the inspection personnel; The locking component on the placement box can lock the position of the upper cover, so as to form a sealed environment inside the placement box, thereby protecting the repeater body. During the process of the upper cover rotating relative to the placement box, the cooperation between the upper cover and the locking component can drive the extrusion component arranged on the placement box to act. When the locking component is triggered, the extrusion force of the extrusion component on the sealing strip decreases, and the sealing strip retracts, which can reduce the friction generated between the upper cover and the placement box when the upper cover is closed. When the locking component is reset, the extrusion component squeezes the sealing strip, which can force the sealing strip to deform, thereby filling the gap between the upper cover and the placement box and improving the airtightness of the placement box, providing a relatively high-level protection for the repeater body to ensure the long-term stable operation of the repeater body.

[0030] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise specified

[0031] The special word "exemplary" here means "serving as an example, embodiment or illustration". Any embodiment described as "exemplary" here is not necessarily to be construed as superior or better than other embodiments

[0032] In addition, for better illustration of the present application, numerous specific details are given in the following detailed embodiments. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, methods, means, elements well known to those skilled in the art are not described in detail so as to highlight the gist of the present application

[0033] Please refer to Figures 1-13 , in an embodiment of the present invention, a repeater includes: A placement box 1, on which an upper cover 2 is rotatably arranged, and the maximum rotation angle of the upper cover 2 relative to the placement box 1 is one hundred and eighty degrees, as Figure 3As shown, a placement table 8 is further provided in the placement box 1. The placement table 8 is used to place the repeater body 9, and the placement table 8 is connected to the upper cover 2 through a lifting assembly. When the upper cover 2 deflects relative to the placement box 1, the lifting assembly can drive the placement table 8 to lift and lower along the longitudinal direction of the placement box 1, so that the placement table 8 can drive the repeater body 9 to lift and protrude or sink into the placement box 1, facilitating the detection or storage of the repeater by the detection personnel; Specifically, the above-mentioned repeater body 9 tightly integrates wireless communication devices such as 5G RRU and antennas in a sealed metal cavity. This integrated structure can effectively reduce space occupation, simplify the installation steps, and reduce the maintenance difficulty; Please refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 , a limiting frame 801 is provided on the above-mentioned placement table 8. A rubber pad is provided on the inner wall of the limiting frame 801. The rubber pad can increase the contact friction between the repeater body 9 and the limiting frame 801, so that the repeater body 9 can be stably placed on the placement table 8; Particularly, the above-mentioned placement box 1 and the upper cover 2 are made of materials with high sealing performance, corrosion resistance, low water absorption, and high moisture resistance, which can prevent water vapor and other corrosive substances from entering the placement box 1 to corrode the repeater body 9, ensuring the long-term stable operation of the repeater body 9.

[0034] The lifting assembly includes a placement table 8 slidably arranged in the placement box 1. Four sets of socket cylinders 18 are provided on the placement table 8. The socket cylinders 18 are evenly distributed around the placement table 8, and the socket cylinders 18 are connected to the placement box 1 through a driving structure and a guiding structure; The driving structure includes mounting members 15 fixedly arranged in the placement box 1. There are two groups of the mounting members 15 arranged along the length direction of the placement box 1. Specifically, the two groups of mounting members 15 are close to the rotating shaft 5 of the upper cover 2. Rotating rods 14 are rotatably mounted on both groups of mounting members 15. A socket cylinder 18 is sleeved on the rotating rod 14. A synaptic part 1801 is formed on the inner wall of the socket cylinder 18. The synaptic part 1801 is slidably arranged in a fitting groove formed on the outer wall of the rotating rod 14. A first spring 13 is also sleeved on the rotating rod 14. One end of the first spring 13 abuts against the mounting member 15, and the other end abuts against the placement table 8; The fitting groove includes a rotating groove 1401 formed in the rotating rod 14. The end of the rotating groove 1401 facing the bottom of the placement box 1 is connected to a horizontal groove 1402. The rotating groove 1401 is spirally opened downward counterclockwise around the rotating rod 14, and the angle between the start end of the rotating groove 1401 and the end of the horizontal groove 1402 is 180 degrees. Specifically, the above-mentioned first spring 13 is always in a compressed state. The compressed first spring 13 can push the placement table 8 to have a tendency to move away from the bottom of the placement box 1. And in the initial state, that is, when the upper cover 2 is in a fully open state, the synaptic body 1801 is located at the forming end of the rotating groove 1401 away from the horizontal groove 1402, and the distance formed between the placement table 8 and the bottom of the placement box 1 is the largest. At this time, the placement table 8 can protrude from the placement box 1, which is convenient for placing the repeater body 9. When the repeater body 9 is placed on the placement table 8, the repeater body 9 completely protrudes from the placement box 1 and is exposed in an area brighter than the inside of the placement box 1, which can provide a well-lit environment for the inspection or installation personnel and facilitate the inspection personnel to conduct a detailed inspection of the repeater body 9. After the inspection personnel complete the inspection of the repeater body 9, close the upper cover 2 counterclockwise (refer to Figure 3 description). During this process, the upper cover 2 can drive the rotating rod 14 to continuously rotate clockwise (refer to Figure 6 ). When the rotating rod 14 rotates clockwise, with the guiding and restricting of the placement table 8 by the guiding structure and the contact extrusion of the synaptic body 1801 by the groove wall of the rotating groove 1401, it can drive the socket cylinder 18 to drive the placement table 8 to descend along the axial direction of the rotating rod 14, so that the repeater body 9 placed on the placement table 8 can gradually move towards the bottom of the placement box 1. When the synaptic body 1801 moves to the end of the rotating groove 1401 and contacts the horizontal groove 1402, the socket cylinder 18 drives the placement table 8 to descend to the lowest height. At this time, the repeater body 9 is immersed in the placement box 1, and the upper cover 2 is about to close. When the upper cover 2 continues to rotate counterclockwise later, the synaptic body 1801 can slide in the horizontal groove 1402 to keep the placement table 8 at the same height. When the upper cover 2 is completely closed, the synaptic body 1801 moves to the end of the horizontal groove 1402, and with the cooperation of the horizontal groove 1402 and the synaptic body 1801, the placement table 8 will not shake up and down in the placement box 1 due to external environmental vibrations, thus increasing the placement stability of the repeater body 9 in the placement box 1.

[0035] Specifically, the guiding structure includes guiding rods 12 fixedly arranged in the placement box 1. There are two groups of guiding rods 12 arranged along the length direction of the placement box 1. The first springs 13 are arranged on both groups of guiding rods 12. One end of the first spring 13 abuts against the placement table 8, and the other end abuts against the retaining piece formed on the guiding rod 12. Specifically, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 , the above two groups of guide rods 12 are far from the rotating shaft 5 of the upper cover 2, and the first springs 13 sleeved on the guide rods 12 are always in a compressed state. In the initial state, with the cooperation of the four groups of first springs 13, the storage table 8 can still maintain the maximum distance from the bottom of the placement box 1 when the direct station body 9 is placed on it. And when the rotating rod 14 drives the storage table 8 to descend, the storage table 8 can further squeeze the first springs 13, so that the elastic potential energy stored in the first springs 13 increases. So that after the upper cover 2 is opened, the first springs 13 release the elastic potential energy, which can force the storage table 8 to drive the direct station body 9 back to the initial height, so that the inspection personnel can inspect the direct station body 9.

[0036] Further, the rotating rod 14 is connected to the upper cover 2 through a trigger assembly. The trigger assembly includes a moving structure and a linkage structure. The moving structure includes an outer attachment box 4 fixedly arranged on the placement box 1. A plug-in cylinder 6 is fixedly arranged on the outer attachment box 4. The rotating shaft 5 of the upper cover 2 is rotatably installed in the plug-in cylinder 6. And a moving sleeve 11 is sleeved on the rotating shaft 5. Two groups of the moving sleeves 11 are symmetrically arranged along the length direction of the rotating shaft 5. A protrusion 1101 is arranged on the inner wall of each group of the moving sleeves 11. The protrusion 1101 is slidably arranged in a spiral groove 501 opened on the rotating shaft 5. The spiral groove 501 is opened clockwise around the rotating shaft 5. And the angle formed between the head and tail ends of the spiral groove 501 and the axis of the rotating shaft 5 is 180 degrees; The linkage structure includes a gear 16 fixedly arranged coaxially with the rotating rod 14. The gear 16 is engaged with a toothed plate 17 slidably arranged in the placement box 1. A connecting rod 10 is fixedly arranged on the toothed plate 17. The connecting rod 10 penetrates through the placement box 1 and is placed in the outer attachment box 4. And one end of the connecting rod 10 far from the toothed plate 17 is fixedly connected to the moving sleeve 11; Specifically, a through groove 101 is opened on the above-mentioned placement box 1. The connecting rod 10 is slidably arranged in the through groove 101. With the cooperation of the through groove 101 and the connecting rod 10, the moving sleeve 11 can only move along the axial direction of the rotating shaft 5. And the rotating shaft 5 is rotatably and sealingly connected to the plug-in cylinder 6. And the outer attachment box 4 covers the through groove 101, so that a communication space is formed between the placement box 1 and the outer attachment box 4. At this time, when the upper cover 2 is closed, a sealed space can be formed in the placement box 1, so as to protect the direct station body 9 and prevent groundwater and other corrosive substances from entering the placement box 1 and causing interference damage to the direct station body 9; Specifically, in the initial state, the upper cover 2 is open, the two moving sleeves 11 are close to each other, and the protrusion 1101 is located at the end of the stroke where the two spiral grooves 501 are close to each other. Refer to Figure 3 , Figure 4 for description. When the upper cover 2 rotates counterclockwise to close, the contact extrusion generated by the groove wall of the spiral groove 501 on the protrusion 1101 can force the two moving sleeves 11 to move away from each other. During the process of the two moving sleeves 11 moving away from each other, the moving sleeve 11 can drive the two toothed plates 17 to move away from each other. At this time, the toothed plate 17 and the gear 16 enter the meshing transmission state, which can drive the rotating rod 14 to rotate clockwise, causing the placement table 8 to gradually sink into the placement box 1, so that the placement box 1 can provide stable protection for the repeater body 9 subsequently.

[0037] Furthermore, please refer to Figure 3 , Figure 5 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 . The placement box 1 is also provided with a sealing strip 7 and a locking component. The locking component can lock the position of the upper cover 2 so that the upper cover 2 cannot rotate relative to the placement box 1. When the locking component acts, the locking component can cooperate with the extrusion component provided on the placement box 1 to extrude the sealing strip 7, thereby increasing the overall sealing performance of the placement box 1; Specifically, an extension frame 102 is fixedly provided on the placement box 1. The extension frame 102 protrudes from the placement box 1, and a placement cavity 104 is also provided on the placement box 1. The above-mentioned sealing strip 7 is placed in the placement cavity 104. With the cooperation of the extension frame 102, the sealing strip 7 can protrude from the extension frame 102 to play a sealing role in closing the upper cover 2 and the placement box 1, so that after the upper cover 2 is closed, a completely closed state can be formed inside the placement box 1, thereby preventing groundwater vapor from causing corrosion damage to the repeater body 9.

[0038] The locking component includes a latch 3 slidably arranged on the placement box 1. Two groups of latches 3 are symmetrically arranged along the length direction of the placement box 1. Each group of latches 3 is connected to a slide bar 21 fixedly arranged on the placement box 1. Two groups of slide bars 21 are symmetrically arranged along the length direction of the latch 3. A second spring 22 is slidably arranged on each group of slide bars 21. One end of the second spring 22 abuts against the latch 3, and the other end abuts against the end of the slide bar 21. A protrusion 301 is fixedly arranged on each latch 3; Preferably, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 9 ,Figure 10 , Figure 11 , Figure 12 , The above-mentioned second spring 22 is always in a compressed state. The second spring 22 in the compressed state pushes the latch 3 to have a tendency to move towards the outside of the placement box 1. A relatively large inclined surface is formed on the side of the latch 3 away from the bottom of the placement box 1. During the process of closing the upper cover 2, the placement table 8 can gradually approach the bottom of the placement box 1. After the height of the placement table 8 is stable, the upper cover 2 contacts the latch 3. Along with the continuous movement of the upper cover 2, the contact extrusion of the inclined surface of the latch 3 caused by the edge of the upper cover 2 can force the latch 3 to retract towards the inside of the placement box 1. During the retraction process, the extrusion assembly is triggered, and the sealing strip 7 retracts into the placement cavity 104 due to its own elastic performance, so that when the upper cover 2 is closed, the friction generated between the upper cover 2 and the placement box 1 is small. And when the latch 3 retracts to the maximum state, continue to rotate the upper cover 2 until the upper cover 2 cannot be rotated. The latch 3 can be combined with the lock groove 201 opened on the upper cover 2. Then the second spring 22 releases its elastic potential energy, which can force the latch 3 back to its initial state. At this time, the latch 3 cooperates with the lock groove 201 to lock the position of the upper cover 2 and prevent the upper cover 2 from deflecting relative to the placement box 1. And during the reset process of the latch 3, the extrusion assembly is triggered again, which can extrude the sealing strip 7, so that the sealing strip 7 deforms and protrudes out of the extension frame 102, thereby filling the gap between the upper cover 2 and the placement box 1, so as to enhance the sealing performance between the upper cover 2 and the placement box 1, and then improve the protection performance of the placement box 1.

[0039] Specifically, the extrusion assembly includes a lifting ring 19. The lifting ring 19 and the sealing strip 7 are both slidably arranged in the placement cavity 104 formed on the placement box 1. And a lifting plate 20 is fixedly arranged on the lifting ring 19. Two groups of the lifting plates 20 are symmetrically arranged along the length direction of the placement box 1. Each group of the lifting plates 20 is provided with an inclined slot 2001. The protruding column 301 is slidably arranged in the inclined slot 2001; The above-mentioned lifting plate 20 is fixedly connected to the lifting ring 19 through a connecting rod. The connecting rod is slidably arranged in the sliding slot 103 opened on the placement box 1. With the cooperation of the sliding slot 103 and the connecting rod, the lifting ring 19 and the lifting plate 20 can only be lifted and lowered along the longitudinal direction of the placement box 1; In the initial state, please refer to Figure 11, the above-mentioned protruding post 301 is located at the end of the travel of the inclined groove 2001 close to the bottom of the placement box 1. At this time, the lifting ring 19 squeezes the sealing strip 7, causing the sealing strip 7 to protrude from the extension frame 102. When the latch 3 is squeezed by the upper cover 2 and retracts, the protruding post 301 cooperates with the inclined groove 2001, which can force the lifting plate 20 to drive the lifting ring 19 to descend in the longitudinal direction. At this time, the extrusion force on the sealing strip 7 decreases, and the phenomenon of inward retraction occurs, thereby reducing the friction when the upper cover 2 is closed. And during the reset process when the latch 3 cooperates with the locking groove 2001, the protruding post 301 cooperates with the inclined groove 2001, which can drive the lifting plate 20 and the lifting ring 19 to squeeze the sealing strip 7, forcing the sealing strip 7 to protrude out of the extension frame 102, thereby filling the gap between the upper cover 2 and the placement box 1, so that a closed environment can be formed inside the placement box 1 and provide a relatively high level of protection for the repeater body 9; When opening the upper cover 2, first press the latch 3 inward, and then rotate the upper cover 2 clockwise to open the upper cover 2. And during the opening process, the rotating shaft 5 rotates reversely, which can force the rotating rod 14 to rotate counterclockwise. During this process, the placement table 8 first maintains the same height. After the upper cover 2 is opened to a certain angle, the placement table 8 can drive the repeater body 9 to rise until the upper cover 2 is opened to the maximum position, and then the placement table 8 returns to the initial height for the inspection personnel to inspect the repeater body 9.

[0040] A usage method of a repeater based on an underground operation network is also proposed. Using a repeater as described above, it includes the following steps: Step 1: Open the upper cover 2 to the maximum extent, and then place the repeater body 9 on the placement table 8. At this time, the repeater body 9 protrudes from the placement box 1, and then close the upper cover 2; Step 2: During the closing process, the rotating shaft 5 of the upper cover 2 can drive the two moving sleeves 11 to move away from each other, thereby driving the toothed plate 17 and the gear 16 into a meshing transmission state, so that the rotating rod 14 rotates continuously in the same direction; Step 3: When the rotating rod 14 rotates, under the cooperation of the socket cylinder 18 and the fitting groove, the placement table 8 drives the repeater body 9 to descend, and then to the lowest height; Step 4: When the placement table 8 descends to the lowest height, the upper cover 2 continues to rotate and the rotating rod 14 continues to rotate. At this time, the height position of the placement table 8 remains unchanged, and the upper cover 2 contacts the locking component, forcing the latch 3 to retract. After the upper cover 2 is completely closed, during the reset process of the latch 3, the extrusion component can squeeze the sealing strip 7, so that the sealing strip 7 protrudes outward, thereby increasing the connection tightness between the upper cover 2 and the extension frame 102.
