Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] Example 1: The specific structure of this utility model is as follows:

[0036] Please refer to the appendix. Figure 1-4 This utility model discloses a repeater with a waterproof and dustproof structure, comprising a power supply unit 2 and a control unit 1, wherein the control unit 1 is rotatably connected to the cover of the control unit 1.

[0037] The control unit 1 includes:

[0038] The cover plate 11 has a first opening groove on its surface, and the first opening groove has a step, with a sealing ring 14 embedded in the step; the cover plate 11 is a metal explosion-proof cover.

[0039] The main control unit 17 is fixed in the first opening slot, and the first signal acquisition unit 15, the second signal acquisition unit 12, the duplexer module 13 and the display module are all electrically connected to the main control unit 17.

[0040] Assembly of the control unit:

[0041] First, the main control unit 17 is fixed to the first opening slot of the cover plate 11 via the back plate 16. The back plate 16 serves to stably support the main control unit 17, ensuring its stability during the operation of the repeater and preventing its performance from being affected by vibration or other factors. During the fixing process, appropriate screws and other fasteners are used to ensure a tight connection between the back plate 16 and the first opening slot, and a secure fit between the main control unit 17 and the back plate 16.

[0042] Next, the first signal acquisition unit 15, the second signal acquisition unit 12, the duplexer module 13, and the display module are electrically connected to the main control unit 17. Suitable methods such as soldering or connector connection can be used for electrical connection to ensure stable and reliable signal transmission between components. For example, during soldering, ensure that the solder joints are full and free of cold solder joints; when using connectors, ensure that the connectors fit tightly and make good contact.

[0043] A sealing ring 14 is embedded in the first opening groove step of the cover plate 11. The sealing ring 14 is made of rubber or other materials with good waterproof and dustproof properties. When embedding, it is necessary to ensure that the sealing ring 14 is completely embedded in the step groove and fits tightly with the step groove without loosening or displacement, so as to form an effective sealing barrier.

[0044] The power supply unit 2 includes:

[0045] The box body 21 has a first opening groove and connecting holes on opposite sides, with the two connecting holes staggered. The cover plate 11 is placed over the box body 21 and sealed by the sealing ring 14. The cover plate 11 and the box body 21 are connected by hinges. Multiple screw holes are provided around the perimeter of the cover end of the box body 21. The cover plate 11 is screwed into the screw holes and locked in place. A grounding terminal 27 is provided on the outer surface of the box body 21. The box body 21 is a metal explosion-proof box body.

[0046] Two flange connectors, namely inlet flange connector 26 and outlet flange connector 22, are installed one-to-one on the outer opening of the two connection holes.

[0047] The adapter terminal block 25 is installed in the first opening slot and near the inlet end of the lattice connector 26, and the wire cores of the adapter terminal block 25 and the lattice connector 26 are electrically connected one-to-one.

[0048] The power module 24 is installed in the first opening slot. The power module 24 is connected to the power terminal of the adapter terminal block 25 and converts the incoming voltage into a stable voltage and outputs it to the main control unit 17.

[0049] Control module 23 is installed in the first opening slot. Control module 23 is electrically connected to the main control unit 17. Control module 23 is used to process data and feedback information from each module to the display module.

[0050] Surge protection module 28 is installed in the first opening slot and is electrically connected to the communication port of the main control unit 17.

[0051] Assembly of Power Supply Unit 2:

[0052] The housing 21 serves as the main body of the power supply unit, and its opposite sides are provided with staggered connection holes. The inlet flange connector 26 and the outlet flange connector 22 are installed one-to-one into the outer openings of the two connection holes. During installation, ensure a good seal between the flange connector and the connection hole. Sealant or other auxiliary materials can be used for sealing to prevent external water, dust, etc., from entering the housing 21 through the connection holes.

[0053] Install an adapter terminal block 25 near the inlet end of the first opening slot in the housing 21, and electrically connect the adapter terminal block 25 to the wire cores of the inlet flange connector 26 one-to-one. During the electrical connection process, ensure a firm connection and good contact. A stable connection can be achieved through crimping or other methods to ensure smooth power transmission.

[0054] Install the power module 24 into the first slot and connect it to the power terminals of the adapter terminal block 25. The power module 24 converts the incoming voltage into a stable voltage. To ensure conversion efficiency and stability, the wiring requirements of the power module 24 must be strictly followed during connection to ensure correctness.

[0055] The control module 23 is installed in the first slot, making it electrically connected to the main control unit 17. The control module 23 is responsible for processing data and feedback information from various modules and sending it to the display module. When connecting, it is necessary to ensure the accuracy and timeliness of signal transmission. Shielded cables or similar materials can be used for connection to reduce signal interference.

[0056] Install the surge protection module 28 in the first slot and electrically connect it to the communication port of the main control unit 17. The surge protection module 28 can effectively protect the repeater from surge voltage. When connecting, ensure that the connection is tight and the contact is good to give full play to its protective function.

[0057] A grounding terminal 27 is installed on the outer side of the housing 21. The grounding terminal 27 is reliably connected to the ground through wires or the like to ensure the electrical safety of the repeater.

[0058] The main control unit 17 is fixed to the first opening slot via a backplate 16. The main control unit 17 is an ARM chip main control unit. The circuit board of the main control unit 17 is also equipped with a WIFI module, which can establish a connection with a mobile phone and control the operation of the repeater through a mobile phone APP.

[0059] The ARM chip main control unit has an AGC automatic gain control mode and an ALC automatic power control mode.

[0060] The duplexer module 13 is provided with a PA power amplifier tube, a first surface acoustic wave (SAW) filter, a PA amplifier tube, an ATT attenuator, a second SAW filter, and an LNA low-noise tube connected in sequence on the downlink. The downlink PA power amplifier tube is connected to the second signal sampling chip, and the ATT attenuator establishes communication with the ARM chip main control unit.

[0061] The uplink setting of the duplexer module 13 is the same as the downlink setting.

[0062] Overall Assembly: Connect the assembled cover plate 11 to the box body 21 via hinges, allowing the cover plate 11 to rotatably fit over the box body 21. After the cover plate 11 is on the box body 21, tighten it by screwing screws into the screw holes around the cover end of the box body 21. During tightening, tighten the screws in a diagonal sequence to ensure a tight fit between the cover plate 11 and the box body 21, fully compressing the sealing ring 14 to achieve a good waterproof and dustproof seal. Since the box body 21 is a metal explosion-proof box and the cover plate 11 is a metal explosion-proof cover, care should be taken during assembly to avoid damaging the explosion-proof surfaces and ensure that the explosion-proof performance is not affected. Example 2

[0063] Signal Acquisition and Processing: The incoming line flange connector 26 introduces external power and signals into the housing 21. Power is transmitted to the power module 24 via the adapter terminal block 25. The power module 24 converts the input voltage, transforming unstable voltage into stable voltage output to the main control unit 17 and other modules requiring power, ensuring the normal operation of all components of the repeater. External signals are transmitted into the main control unit 17, processed by the main control unit 17, and then transmitted outwards via the antenna.

[0064] The main control unit 17 has a WIFI module on its circuit board, enabling wireless communication between the repeater and external devices, facilitating remote monitoring and management of the repeater by staff. Simultaneously, the surge protection module 28 monitors the voltage at the communication port of the main control unit 17 in real time. When a surge voltage occurs, it promptly suppresses and absorbs it, protecting the main control unit 17 and other communication equipment from damage and ensuring the stability and reliability of the repeater's communication.

[0065] When maintenance and repair of the repeater are required, unscrew the screws between the cover plate 11 and the box body 21 to open the cover plate 11. Due to its waterproof and dustproof structure, the interior of the box body 21 is usually relatively clean, reducing maintenance workload. Personnel can then inspect the various components of the control and power supply sections, checking for loose connections, damage, etc. Faulty components can be directly replaced or repaired. After repair, reinstall the cover plate 11 and seal and tighten it according to the assembly requirements described above to ensure the repeater returns to its normal waterproof and dustproof performance and operating condition.

[0066] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
