Description

Technical Field

[0001] The invention relates to the technical field of mobile base station cabinets, and in particular to a high-stability mobile base station cabinet with a fireproof function. Background Art

[0002] Mobile base stations are the most critical infrastructure in mobile communication networks. Mobile base station cabinets are equipment that provides an outdoor physical working environment and safety system for baseband processing units. Base station processing units are an important part of mobile communication networks. They can directly affect the operation and communication quality of the entire base station. Protecting baseband processing units is an important task. Since there are a large number of communication components in mobile base station cabinets, there is a great fire hazard. If the fire cannot be extinguished in time, the fire will quickly spread to various places along various power lines, causing large-scale economic losses. Therefore, mobile base station cabinets have high fire prevention requirements.

[0003] Most of the existing fireproof cabinets are designed to extinguish the fire of the entire cabinet after detecting a fire. Although this can extinguish the fire in time, if only a small area in the cabinet is on fire, the entire cabinet is still extinguished, which not only affects the work of other communication components that are not on fire, but also causes a waste of resources. Therefore, it is necessary to invent a high-stability mobile base station cabinet with fireproof function to solve the above problems. Summary of the invention

[0004] In view of the above problems, the present invention proposes a high-stability mobile base station cabinet with fire prevention function, and the technical solution used is: A high-stability mobile base station cabinet with fire prevention function, comprising a shell, a cabinet body fixedly installed inside the shell, a supporting device arranged at the bottom of the shell, a ventilation device installed on the side of the cabinet body, and a local fire extinguishing device and an overall fire extinguishing device installed inside the shell; A roller is installed at the bottom of the shell; a plurality of cabinet units are arranged inside the cabinet; a camera is installed inside the cabinet unit; a ventilation window is arranged on the cabinet; The local fire extinguishing device comprises a gas fire extinguishing agent tank fixedly installed inside the shell, a lifting frame slidably installed inside the shell, a unit cover box slidably installed on the lifting frame, and a nozzle installed in the unit cover box and connected to the gas fire extinguishing agent tank; The integrated fire extinguishing device comprises a gas fire extinguishing agent tank 2 fixedly installed inside the shell, a guide tube rotatably installed on the cabinet and connected to the gas fire extinguishing agent tank 2, and a nozzle 2 fixedly installed on the guide tube and connected to the guide tube.

[0005] Furthermore, the supporting device includes a supporting block that is slidably and elastically installed on the outer shell, a fixing rod that is slidably installed on the outer shell, a linkage frame that is slidably installed on the outer shell and drives the supporting block to move, a brake plate that is fixedly installed on the linkage frame and intermittently close to the roller, and a clamping rod installed on the linkage frame; a fixing hole is provided on the supporting block corresponding to the fixing rod; and a clamping hole is provided on the outer shell corresponding to the clamping rod.

[0006] Furthermore, the supporting device also includes a connecting shaft rotatably mounted on the outer shell, an output bevel gear coaxially fixedly mounted on the connecting shaft, an input bevel gear meshing with the output bevel gear, a linkage gear rotatably mounted on the outer shell and coaxially fixedly connected to the input bevel gear, a linkage rack fixedly mounted on the linkage frame and meshing with the linkage gear, and a support leg rotatably mounted on the connecting shaft.

[0007] Furthermore, a coil spring is provided between the connecting shaft and the supporting leg.

[0008] Furthermore, the ventilation device includes a servo screw 1 installed on the cabinet, and a baffle slidably installed on the cabinet and driven to slide by the servo screw 1; the baffle intermittently blocks the ventilation window.

[0009] Furthermore, the local fire extinguishing device also includes a servo screw 2 installed inside the shell; the lifting frame is threadedly connected to the servo screw 2.

[0010] Furthermore, the local fire extinguishing device also includes a servo motor 1 fixedly mounted on the lifting frame, and a cam 1 whose base circle center is coaxially fixedly connected to the output end of the servo motor 1; the protrusion of the cam 1 is slidably and rotatably connected to the unit cover box.

[0011] Furthermore, the integrated fire extinguishing device also includes a driving frame slidably mounted on the outer shell, a driving rack fixedly mounted on the driving frame, and a driving gear fixedly mounted on the guide cylinder and meshing with the driving rack.

[0012] Furthermore, the integrated fire extinguishing device also includes a servo motor 2 fixedly mounted on the cabinet, and a cam 2 whose base circle center is coaxially fixedly connected to the output end of the servo motor 2; the protrusion of the cam 2 intermittently lifts the drive frame.

[0013] Furthermore, a smoke sensor is integrated into the camera.

[0014] Since the present invention adopts the above technical solution, the present invention has the following advantages: 1. The present invention adopts different fire extinguishing methods according to different fire conditions through the coordinated design of local fire extinguishing devices and overall fire extinguishing devices. If only one cabinet unit is on fire, the local fire extinguishing device is activated, otherwise the overall fire extinguishing device is activated. In this way, the fire can be handled according to the specific fire condition, and the operation of the communication components in other cabinet units will not be affected when only one cabinet unit is on fire.

[0015] 2. The support device of the present invention can stabilize the mobile base station cabinet on the ground through the design of the support block and the support leg. When the support block and the support leg are lowered, the roller is tightly attached to the brake plate and no longer rotates, thereby improving the overall stability of the mobile base station cabinet; when the support block and the support leg are retracted, the brake plate is detached from the roller and will not affect the rolling of the roller.

[0016] 3. The ventilation device of the present invention can timely ventilate and dissipate heat inside the mobile base station cabinet, and isolate the air when a fire is detected, control the fire, and reduce smoke leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figure 7-Figure 9 and Figure 13-Figure 16 As shown, the integral fire extinguishing device 6 comprises a gas fire extinguishing agent tank 601, a servo motor 602, a cam 603, a driving frame 604, a driving rack 605, a driving gear 606, a guide tube 607 and a nozzle 608; the gas fire extinguishing agent tank 601 is fixedly installed in the housing 1; two cams 603 are provided, and the base circle centers of the two cams 603 are coaxially fixedly connected together through a connecting shaft; the servo motor 602 is fixedly installed on the top of the cabinet 2, and its output end is coaxially fixedly connected with the base circle centers of the two cams 603; the driving frame 604 is vertically slidably installed on the housing 1, and is elastically connected to the top of the cabinet 2 through a tension spring; the protrusion of the cam 603 intermittently lifts the driving frame 604; Each cabinet unit 201 corresponds to a second nozzle 608; the second nozzle 608 is installed on the upper guide tube 607 and is connected with the corresponding guide tube 607; the guide tube 607 is rotatably installed on the outer side of the corresponding cabinet unit 201 through a rotating shaft, and is connected with the second gas fire extinguishing agent tank 601 through a pipeline; the second gas fire extinguishing agent tank 601 is installed with a second air pump; a driving gear 606 is coaxially fixedly installed on the rotating shaft of each guide tube 607; each driving gear 606 is meshed with a driving rack 605 vertically fixedly installed on the driving frame 604; Specifically, the air pump 2 is started, and the gas fire extinguishing agent tank 2 601 delivers the gas fire extinguishing agent to the nozzle 2 608 through the guide tube 607; the servo motor 2 602 drives the two cams 2 603 to rotate, and the protrusion of the cam 2 603 lifts the driving frame 604, and the driving frame 604 drives the driving rack 605 to move upward, and the driving rack 605 drives the driving gear 606 to rotate 150°, and the guide tube 607 rotates 150° accordingly, and the four nozzles 2 608 move to spray the gas fire extinguishing agent into the four cabinet units 201 and even the entire cabinet 2; after the protrusion of the cam 2 603 is separated from the driving frame 604, the driving frame 604 drives the driving rack 605 to move downward, and the guide tube 607 rotates in the opposite direction to its original position; in this way, the cam 2 603 repeatedly lifts the driving frame 604, so that the nozzle 2 608 moves back and forth to perform the fire extinguishing work.

[0036] The camera 202 is integrated with a smoke sensor and a temperature sensor for real-time monitoring of the internal conditions of the cabinet unit 201 .

[0037] like Fig.17 As shown, the control terminal 7 includes a main controller, a human-machine interactive display screen, an information transmission module, a storage module and a power module, and the main controller is electrically connected to the human-machine interactive display screen, the information transmission module, the storage module, the power module, and the camera 202, the servo screw 1 401, the air pump 1, the servo screw 2 504, the servo motor 1 505, the air pump 2, and the servo motor 2 602; the main controller is used to control the operation of the entire mobile base station cabinet; the human-machine interactive display screen is used to observe the internal situation of the cabinet unit 201 through the camera 202, and to control the opening and closing of other electrical components; the information transmission module is used for information transmission between the main controller and other electrical components; the power module is used to provide a stable power supply for the control terminal 7; the storage module is used to store the operation information data of the entire mobile base station cabinet.

[0038] This embodiment works away from: After the entire mobile base station cabinet is pushed to the work site by rollers, the operator pushes the linkage frame 303 outward, the support block 301 moves down and is supported on the ground, the brake plate 304 is close to the roller 101, the support leg 311 is flipped downward and supported on the ground, and then the operator inserts the fixing rod 302 into the corresponding fixing hole 3011, and inserts the clamping rod 305 into the clamping hole, and the entire mobile base station cabinet is stably placed at the work site.

[0039] The camera 202 inside the mobile base station cabinet monitors the internal situation of the cabinet unit 201 in real time. When the smoke sensor detects smoke or the camera 202 detects fire, a signal will be transmitted to the control terminal 7, and the control terminal 7 will perform fire extinguishing work.

[0040] If only one cabinet unit 201 is on fire, the servo screw 2 504 and the servo motor 1 505 are started to drive the unit cover box 503 to move to the cabinet unit 201 where the fire is. When the air pump is started, the nozzle 1 507 sprays the gas fire extinguishing agent into the cabinet unit 201 to extinguish the fire in a targeted manner, without affecting the communication components in other cabinet units 201. If more than one cabinet unit 201 is on fire, or fire is detected in the entire cabinet 2, the servo motor 2 602 is started, the drive frame 604 is repeatedly lifted, the air pump 2 is started, and the four nozzles 2 608 spray gas fire extinguishing agent into all cabinet units 201 and even the entire cabinet 2, so as to quickly control the fire and avoid causing greater losses.

[0041] When the temperature sensor detects a high temperature, the control end 7 will start the servo screw 401 at a fixed time to open the baffle 402 to allow the ventilation window 203 to ventilate and cool down; when a fire is detected, the servo screw 401 drives the baffle 402 to cover the ventilation window 203, controlling the fire by isolating the air and reducing smoke leakage at the same time.
