Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of repeaters, in particular to a repeater and a use method of the repeater based on an underground operation network. BACKGROUND

[0002] 5G signals have weak diffraction ability due to high frequency, and 5G macro base station signals deployed in the high frequency band also face a large link loss problem when penetrating walls indoors. Indoor deep coverage is limited because 5G networks use millimeter wave technology, which is a kind of electromagnetic wave with weak penetration and rapid attenuation. This determines its weak anti-interference ability. In addition, 5G signals have poor penetration, so the signal coverage range of a general 5G base station is usually only 200 meters. Therefore, a repeater is needed to compensate for the lack of 5G signal coverage, expand the coverage range of the base station, fill the coverage blind area, reduce the cost of network coverage, and promote the development of 5G.

[0003] However, the signal transmission of the repeater is easily affected by the geographical environment, especially the repeater for the underground operation network. Not only does it need to overcome the undulating mountainous area, the turbulent hydropower station and other extreme terrain, but also needs to avoid the interference of underground water vapor and dust. These factors not only affect the performance of the equipment, but also affect its working stability. Long-term use in such a humid underground environment can easily cause the modules inside the repeater to be corroded and damaged, thereby affecting the signal and development of the 5G network. SUMMARY

[0004] The present application aims to provide a repeater and a use method of the repeater based on an underground operation network to solve the problems raised in the background.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0006] A repeater comprises a placing box, an upper cover is rotatably arranged on the placing box, and a placing table is further arranged in the placing box. The placing table is used for placing a repeater body, and the placing table is connected with the upper cover through a lifting assembly. When the upper cover is deflected relative to the placing box, the lifting assembly can drive the placing table to ascend and descend along the longitudinal direction of the placing box, so that the placing table can lift the repeater body out of the placing box or immerse the repeater body into the placing box, thereby facilitating detection personnel to detect or store the repeater;

[0007] The placing box is further provided with a sealing strip and a locking assembly, the locking assembly can lock the position of the upper cover, so that the upper cover cannot rotate relative to the placing box, and when the locking assembly acts, the locking assembly can cooperate with the extrusion assembly arranged on the placing box to extrude the sealing strip, thereby increasing the overall sealing performance of the placing box.

[0008] The direct broadcast station as claimed in any one of the preceding claims: the lifting assembly comprises a placing table slidingly arranged in the placing box, four sets of sleeve sockets are arranged on the placing table, the sleeve sockets are uniformly distributed around the placing table, and the sleeve sockets are connected with the placing box through driving structures and guide structures.

[0009] The direct broadcast station as claimed in any one of the preceding claims: the driving structures comprise mounting pieces fixedly arranged in the placing box, two sets of mounting pieces are arranged along the length direction of the placing box, rotating rods are rotatably mounted on the two sets of mounting pieces, sleeve sockets are sleeved on the rotating rods, protrusions are formed on the inner walls of the sleeve sockets, the protrusions are slidingly arranged in the embedded grooves formed on the outer walls of the rotating rods, and first springs are further sleeved on the rotating rods, one end of each first spring is in abutment with the mounting piece, and the other end is in abutment with the placing table.

[0010] The direct broadcast station as claimed in any one of the preceding claims: the embedded grooves comprise rotating grooves formed on the rotating rods, and horizontal grooves are connected to the end of the travel of the rotating grooves towards the bottom of the placing box.

[0011] The direct broadcast station as claimed in any one of the preceding claims: the guide structures comprise guide rods fixedly arranged in the placing box, two sets of guide rods are arranged along the length direction of the placing box, the first springs are arranged on the two sets of guide rods, one end of each first spring is in abutment with the placing table, and the other end is in abutment with the flaps formed on the guide rods.

[0012] The direct broadcast station as claimed in any one of the preceding claims: the rotating rods are connected with the upper cover through a triggering assembly, the triggering assembly comprises moving structures and linkage structures, the moving structures comprise an outer attached box fixedly arranged on the placing box, a plug-in sleeve is fixedly arranged on the outer attached box, a rotating shaft of the upper cover is rotatably mounted in the plug-in sleeve, 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 arranged on the inner walls of each moving sleeve, and the protrusions are slidingly arranged in the spiral grooves formed on the rotating shaft.

[0013] As described above, the repeater includes a gear fixedly coaxially with the rotating rod, the gear meshing with a toothed plate slidably disposed in the placement box, a connecting rod fixedly disposed on the toothed plate, the connecting rod passing through the placement box and placed in the outer auxiliary box, and the end of the connecting rod away from the toothed plate being fixedly connected to the movable sleeve.

[0014] As described above, the locking assembly includes a latch slidably disposed on the placement box. Two sets of latches are symmetrically arranged along the length of the placement box. Each set of latches is connected to a slide rod fixedly disposed on the placement box. Two sets of slide rods are symmetrically arranged along the length of the latches. A second spring is slidably disposed on each set of slide rods. One end of the second spring abuts against the latch, and the other end abuts against the end of the slide rod. A protrusion is fixedly disposed on each latch.

[0015] As described above, the extrusion assembly includes a lifting ring, and the lifting ring and the sealing strip are slidably disposed in the placement cavity formed on the placement box. A lifting plate is fixedly disposed on the lifting ring. Two sets of lifting plates are symmetrically disposed along the length direction of the placement box. Each set of lifting plates is provided with an inclined groove, and the protrusion is slidably disposed in the inclined groove.

[0016] A method for using a repeater based on an underground operation network is also proposed, employing a repeater as described above, including the following steps:

[0017] Step 1: Open the top cover to the maximum extent, then place the repeater body on the shelf. At this time, the repeater body will protrude from the shelf. Then close the top cover.

[0018] Step 2: During the closing process, the rotating shaft of the upper cover can drive the two sets of moving sleeves to move away from each other, thereby driving the toothed plate and gear into a meshing transmission state, so that the rotating rod can rotate continuously in the same direction;

[0019] Step 3: When the rotating rod rotates, with the cooperation of the sleeve and the fitting groove, the platform drives the repeater body to descend, and then descends to the lowest height;

[0020] Step 4: When the platform descends to its lowest height, the top cover continues to rotate, and the rotating rod continues to rotate. At this time, the height of the platform remains unchanged. The top cover contacts the locking assembly, forcing the latch to retract. After the top cover is fully closed, during the latch reset process, the squeezing assembly can squeeze the sealing strip to make the sealing strip protrude outward, thereby increasing the sealing between the top cover and the extension frame.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The repeater body is placed in a storage box with high sealing performance, corrosion resistance, low water absorption and high moisture resistance. The storage box can protect the repeater body and reduce the contact between water vapor and other corrosive substances and the repeater body.

[0023] Meanwhile, by setting up lifting and triggering components, the position of the repeater body is restricted by the placement platform, making it difficult for the repeater body to move relative to the placement platform. During the opening or closing of the top cover, the triggering and lifting components work together to control the placement platform to lift the repeater body along the longitudinal direction of the placement box. When the top cover is fully open, the placement platform can make the repeater body protrude out of the placement box, exposing the repeater body outside the placement box. This allows the testing personnel to disassemble, install, or inspect the repeater body in a relatively bright environment, thus providing convenience for the testing personnel.

[0024] The locking assembly on the placement box can lock the position of the top cover, creating a sealed environment inside the box and protecting the repeater. As the top cover rotates relative to the placement box, the interaction between the top cover and the locking assembly activates a pressing assembly on the placement box. When the locking assembly is triggered, the pressing force on the sealing strip decreases, causing the sealing strip to retract. This reduces friction between the top cover and the placement box when the top cover is closed. When the locking assembly resets, the pressing assembly compresses the sealing strip, forcing it to deform and filling the gap between the top cover and the placement box, improving the box's airtightness and providing a high level of protection for the repeater, ensuring its long-term stable operation.

[0039] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0040] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0041] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0042] Please see Figures 1-13 In this embodiment of the invention, a repeater includes:

[0043] A placement box 1 is provided with a top cover 2 that is rotatably mounted on the placement box 1. The maximum rotation angle of the top cover 2 relative to the placement box 1 is 180 degrees. Figure 3 As shown, the placement box 1 is also provided with a platform 8, which is used to place the repeater body 9. The platform 8 is connected to the upper cover 2 through a lifting assembly. When the upper cover 2 is deflected relative to the placement box 1, the lifting assembly can drive the platform 8 to rise and fall along the longitudinal direction of the placement box 1, so that the platform 8 can lift the repeater body 9 to protrude or be submerged in the placement box 1, thereby facilitating the testing personnel to test or store the repeater.

[0044] In detail, the repeater body 9 mentioned above integrates 5G RRU and wireless communication equipment such as antennas into a sealed metal cavity. This integrated structure can effectively reduce space occupation, simplify installation steps, and reduce maintenance difficulty.

[0045] Please see Figure 3 , Figure 5 , Figure 6 , Figure 7 The aforementioned platform 8 is provided with a limiting frame 801, and the inner wall of the limiting frame 801 is provided with a rubber pad. 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 platform 8.

[0046] In particular, the aforementioned placement box 1 and the top 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 and corroding the repeater body 9, so as to ensure the long-term stable operation of the repeater body 9.

[0047] The lifting assembly includes a platform 8 that is slidably disposed in the placement box 1. The platform 8 is provided with four sets of sleeves 18. The sleeves 18 are evenly distributed around the platform 8, and the sleeves 18 are connected to the placement box 1 through a driving structure and a guiding structure.

[0048] The driving structure includes a mounting component 15 fixedly disposed inside the placement box 1. Two sets of mounting components 15 are arranged along the length of the placement box 1. Specifically, the two sets of mounting components 15 are close to the rotating shaft 5 of the upper cover 2. A rotating rod 14 is rotatably mounted on each set of mounting components 15. A sleeve 18 is sleeved on the rotating rod 14. A protrusion 1801 is formed on the inner wall of the sleeve 18. The protrusion 1801 is slidably disposed in a fitting groove opened 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 component 15, and the other end abuts against the placement platform 8.

[0049] The fitting groove includes a rotating groove 1401 formed on 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 spiraled downward counterclockwise around the rotating rod 14. The angle between the beginning of the stroke of the rotating groove 1401 and the end of the stroke of the horizontal groove 1402 is 180 degrees.

[0050] In detail, the first spring 13 is always in a compressed state. In the compressed state, the first spring 13 can push the platform 8 away from the bottom of the placement box 1. In the initial state, that is, when the top cover 2 is fully open, the protrusion 1801 is located at the end of the rotating groove 1401 away from the horizontal groove 1402. The distance between the platform 8 and the bottom of the placement box 1 is the largest. At this time, the platform 8 can protrude from the placement box 1, which can facilitate the placement of the repeater body 9. When the repeater body 9 is placed on the platform 8, the repeater body 9 protrudes completely from the placement box 1 and is exposed to a brighter area than the inside of the placement box 1. This can provide a well-lit environment for the testing or installation personnel, making it convenient for the testing personnel to conduct detailed testing on the repeater body 9.

[0051] After the inspectors have completed the inspection of the repeater body 9, they close the top cover 2 counterclockwise (refer to...). Figure 3 (Description), during this process, the upper cover 2 can drive the rotating rod 14 to rotate continuously clockwise (see description). Figure 6When the rotating rod 14 rotates clockwise, the guide structure guides and restricts the platform 8. The contact compression between the wall of the rotating groove 1401 and the surge 1801 drives the sleeve 18 to lower the platform 8 along the axial direction of the rotating rod 14. This allows the repeater body 9 placed on the platform 8 to gradually move towards the bottom of the storage box 1. When the surge 1801 reaches the end of the stroke of the rotating groove 1401 and contacts the horizontal groove 1402, the sleeve 18 lowers the platform 8 to its lowest height. When the repeater body 9 is submerged in the placement box 1 and the top cover 2 is about to close, as the top cover 2 continues to rotate counterclockwise, the contact 1801 can slide within the horizontal groove 1402 to keep the platform 8 at the same height. When the top cover 2 is completely closed, the contact 1801 moves to the end of the stroke of the horizontal groove 1402. With the cooperation of the horizontal groove 1402 and the contact 1801, the platform 8 will not sway up and down within the placement box 1 due to external environmental vibrations, thereby increasing the stability of the repeater body 9 within the placement box 1.

[0052] In detail, the guide structure includes a guide rod 12 fixedly installed in the placement box 1. Two sets of guide rods 12 are arranged along the length direction of the placement box 1. The first spring 13 is provided on both sets of guide rods 12. One end of the first spring 13 abuts against the placement platform 8, and the other end abuts against the baffle formed on the guide rod 12.

[0053] For details, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 The two sets of guide rods 12 are far from the pivot 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 sets of first springs 13, the platform 8 can still maintain the maximum distance from the bottom of the placement box 1 when the repeater body 9 is placed on it. When the rotating rod 14 drives the platform 8 to descend, the platform 8 can further compress the first springs 13, so that the elastic potential energy stored in the first springs 13 increases. After the upper cover 2 is opened, the first springs 13 release elastic potential energy, which can force the platform 8 to drive the repeater body 9 back to the initial height so that the testing personnel can test the repeater body 9.

[0054] Furthermore, the rotating rod 14 is connected to the upper cover 2 via a trigger assembly. The trigger assembly includes a moving structure and a linkage structure. The moving structure includes an outer box 4 fixedly mounted on the placement box 1. A plug-in cylinder 6 is fixedly mounted on the outer box 4. The rotating shaft 5 of the upper cover 2 is rotatably mounted inside the plug-in cylinder 6. A movable sleeve 11 is sleeved on the rotating shaft 5. Two sets of movable sleeves 11 are symmetrically arranged along the length of the rotating shaft 5. Each set of movable sleeves 11 has a protrusion 1101 on its inner wall. The protrusion 1101 is slidably disposed 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 beginning and end ends of the spiral groove 501 and the axis of the rotating shaft 5 is 180 degrees.

[0055] The linkage structure includes a gear 16 fixedly coaxially with the rotating rod 14. The gear 16 meshes with a toothed plate 17 slidably disposed in the placement box 1. A connecting rod 10 is fixedly disposed on the toothed plate 17. The connecting rod 10 passes through the placement box 1 and is placed in the outer auxiliary box 4. The end of the connecting rod 10 away from the toothed plate 17 is fixedly connected to the movable sleeve 11.

[0056] In detail, the aforementioned placement box 1 is provided with a through groove 101, and the aforementioned connecting rod 10 is slidably disposed in the through groove 101. With the cooperation of the through groove 101 and the connecting rod 10, the movable sleeve 11 can only move along the axial direction of the rotating shaft 5, and the aforementioned rotating shaft 5 is sealed and rotatably connected to the plug-in cylinder 6. The outer auxiliary box 4 covers the through groove 101, so that a communicating space is formed between the placement box 1 and the outer auxiliary box 4. At this time, when the upper cover 2 is closed, a sealed space can be formed inside the placement box 1, thereby protecting the repeater body 9 and preventing groundwater and other corrosive substances from entering the placement box 1 and causing interference or damage to the repeater body 9.

[0057] Specifically, in the initial state, the upper cover 2 is open, the two sets of moving sleeves 11 are close to each other, and the protrusion 1101 is located at the end of the stroke where the two sets of spiral grooves 501 are close to each other, as shown in the figure. Figure 3 , Figure 4 The description states that when the top cover 2 is closed by rotating counterclockwise, the contact compression generated by the groove wall of the spiral groove 501 on the protrusion 1101 can force the two sets of movable sleeves 11 to move away from each other. During the process of the two sets of movable sleeves 11 moving away from each other, the movable sleeves 11 can drive the two sets of toothed plates 17 to move away from each other. At this time, the toothed plates 17 and the gears 16 enter the meshing transmission state, which can drive the rotating rod 14 to rotate clockwise, so that the platform 8 can gradually sink into the placement box 1, so that the subsequent placement box 1 can provide stable protection for the repeater body 9.

[0058] For further details, please refer to [link / reference]. 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 is activated, the locking component can cooperate with the pressing component provided on the placement box 1 to press the sealing strip 7, thereby increasing the overall sealing performance of the placement box 1.

[0059] Specifically, an extension frame 102 is fixedly installed on the aforementioned 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 aforementioned sealing strip 7 is placed in the placement cavity 104, and with the cooperation of the extension frame 102, the sealing strip 7 can protrude from the extension frame 102, which plays a sealing role in closing the upper cover 2 and the placement box 1, so that after the upper cover 2 is closed, the placement box 1 can form a completely sealed state, thereby preventing groundwater vapor from causing corrosion damage to the repeater body 9.

[0060] The locking assembly includes a latch 3 slidably disposed on the placement box 1. Two sets of latches 3 are symmetrically arranged along the length direction of the placement box 1. Each set of latches 3 is connected to a slide rod 21 fixedly disposed on the placement box 1. Two sets of slide rods 21 are symmetrically arranged along the length direction of the latches 3. A second spring 22 is slidably disposed on each set of slide rods 21. One end of the second spring 22 abuts against the latch 3, and the other end abuts against the end of the slide rod 21. A protrusion 301 is fixedly disposed on each latch 3.

[0061] For preferred options, please refer to [link / reference]. Figure 3 , Figure 4 , Figure 5 , Figure 9 , Figure 10 , Figure 11 , Figure 12The second spring 22 is always in a compressed state. In this compressed state, the second spring 22 pushes the latch 3 towards the outside of the storage box 1. The latch 3 has a large inclined surface on the side furthest from the bottom of the storage box 1. As the top cover 2 closes, the platform 8 gradually approaches the bottom of the storage box 1. Once the height of the platform 8 stabilizes, the top cover 2 contacts the latch 3. With the continued movement of the top cover 2, the edge of the top cover 2 presses against the inclined surface of the latch 3, forcing the latch 3 to retract towards the inside of the storage box 1. During this retraction, the pressing component is triggered, and the sealing strip 7 retracts into the storage cavity 104 due to its elasticity, thus minimizing friction between the top cover 2 and the storage box 1 when the top cover 2 is closed. Furthermore, after the locking 3 retracts to its maximum state, the upper cover 2 continues to rotate until it can no longer rotate. At this point, the locking 3 engages with the locking groove 201 on the upper cover 2. Then, the second spring 22 releases its elastic potential energy, forcing the locking 3 back to its initial state. At this time, the locking 3 and the locking groove 201 work together to lock the position of the upper cover 2, preventing the upper cover 2 from deflecting relative to the placement box 1. During the reset process of the locking 3, the compression component is triggered again, which can compress the sealing strip 7, causing the sealing strip 7 to deform and protrude outward from the extension frame 102, thereby filling the gap between the upper cover 2 and the placement box 1, enhancing the sealing performance between the upper cover 2 and the placement box 1, and thus improving the protective performance of the placement box 1.

[0062] Specifically, the extrusion assembly includes a lifting ring 19, and the lifting ring 19 and the sealing strip 7 are slidably disposed in the placement cavity 104 formed on the placement box 1. A lifting plate 20 is fixedly disposed on the lifting ring 19. Two sets of lifting plates 20 are symmetrically disposed along the length direction of the placement box 1. Each set of lifting plates 20 is provided with an inclined groove 2001. The protruding post 301 is slidably disposed in the inclined groove 2001.

[0063] The aforementioned lifting plate 20 is fixedly connected to the lifting ring 19 via a connecting rod. The connecting rod is slidably disposed in the slide groove 103 opened on the placement box 1. With the cooperation of the slide groove 103 and the connecting rod, the lifting ring 19 and the lifting plate 20 can only be raised and lowered along the longitudinal direction of the placement box 1.

[0064] In the initial state, please refer to Figure 11The aforementioned protruding post 301 is located at the end of the travel of the inclined groove 2001 near 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 locking 3 is squeezed by the upper cover 2 and retracts, the protruding post 301 cooperates with the inclined groove 2001 to force the lifting plate 20 to drive the lifting ring 19 to descend in the longitudinal direction. At this time, the compression on the sealing strip 7 is reduced, and the phenomenon of inward retraction occurs, thereby reducing the friction on the upper cover 2 when it is closed. In the process of the locking 3 and the locking groove 201 resetting, the protruding post 301 cooperates with the inclined groove 2001 to drive the lifting plate 20 and the lifting ring 19 to squeeze the sealing strip 7, forcing the sealing strip 7 to protrude outward from the extension frame 102, thereby filling the gap between the upper cover 2 and the placement box 1, so that the interior of the placement box 1 can form a sealed environment and provide a higher level of protection for the repeater body 9.

[0065] When opening the top cover 2, first press the latch 3 inward, and then rotate the top cover 2 clockwise to open it. During the opening process, the rotating shaft 5 reverses, which forces the rotating rod 14 to rotate counterclockwise. During this process, the platform 8 is initially kept at the same height. After the top cover 2 is opened to a certain angle, the platform 8 can drive the repeater body 9 to rise until the top cover 2 is opened to the maximum position. Then the platform 8 returns to the initial height so that the inspection personnel can inspect the repeater body 9.

[0066] A method for using a repeater based on an underground operation network is also proposed, employing a repeater as described above, including the following steps:

[0067] Step 1: Open the top cover 2 to the maximum extent, then place the repeater body 9 on the shelf 8. At this time, the repeater body 9 protrudes from the shelf box 1, and then close the top cover 2.

[0068] Step 2: During the closing process, the rotating shaft 5 of the upper cover 2 can drive the two sets of 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 can rotate continuously in the same direction.

[0069] Step 3: When the rotating rod 14 rotates, with the cooperation of the sleeve 18 and the fitting groove, the platform 8 drives the repeater body 9 to descend, and then descends to the lowest height;

[0070] Step 4: When the shelf 8 descends to its lowest height, the top cover 2 continues to rotate, and the rotating rod 14 continues to rotate. At this time, the height of the shelf 8 remains unchanged. The top cover 2 contacts the locking assembly, forcing the latch 3 to retract. After the top cover 2 is completely closed, during the reset process of the latch 3, the squeezing assembly can squeeze the sealing strip 7 to make the sealing strip 7 protrude outward, thereby increasing the sealing between the top cover 2 and the extension frame 102.

[0071] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
