Description

Technical Field

[0001] This invention relates to the field of communication base station technology, specifically to an emergency communication base station. Background Technology

[0002] During sudden natural disasters such as earthquakes, floods, and typhoons, existing communication infrastructure in a region is often severely damaged, leading to communication disruptions. Uninterrupted communication is crucial for emergency rescue, disaster reporting, evacuation, and assistance to affected populations. A communication breakdown not only delays rescue efforts but can also exacerbate casualties and property damage. Emergency communication base stations, as key equipment for post-disaster communication restoration, directly determine the efficiency and sustainability of emergency communication support through their rapid deployment capabilities and stable power supply. Therefore, these two factors are core considerations in the research, development, and application of emergency communication base stations.

[0003] Currently, emergency communication base stations are mainly divided into two categories: fixed and mobile. Among them, mobile emergency base stations are widely used in post-disaster emergency communication support scenarios due to their advantages of being relocatable and flexible in deployment. Moreover, existing mobile emergency base stations generally adopt telescopic mast structures, which can realize the raising and lowering of the mast to meet communication height requirements. However, existing mobile emergency base stations still have many significant shortcomings in terms of deployment efficiency and energy supply, which seriously restrict their emergency support effectiveness: First, the deployment process is cumbersome. Even with the existing telescopic mast structure, most base stations are large and heavy. During deployment, hoisting equipment or multiple staff members are still needed to adjust the base station to a vertical position. This not only consumes a lot of manpower and resources but also seriously affects deployment efficiency, failing to meet the core needs of "rapid response and instant communication" after a disaster. Especially during the golden period of rescue, deployment delays may cause irreparable losses. Second, the energy supply is unstable. Base station operation requires continuous and stable power support. Existing emergency base stations mostly rely on external power sources or their own fuel generators. External power sources are often unusable after a disaster due to infrastructure damage. Fuel generators have problems such as high fuel consumption, serious noise pollution, and inconvenient maintenance. Moreover, fuel reserves are limited, making it difficult to achieve long-term stable operation of base stations and easily leading to communication interruptions due to power outages. Summary of the Invention

[0004] This invention provides an emergency communication base station to solve the problems of inconvenient deployment and unstable energy supply of existing emergency communication base stations.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: An emergency communication base station includes a mast mechanism and a support mechanism. The mast mechanism includes an outer cylinder, a middle cylinder, and an inner cylinder arranged sequentially from the outside to the inside. Photovoltaic panels are installed on the outer surfaces of the middle cylinder and the inner cylinder. A storage battery is installed at the bottom of the outer cylinder. The storage battery is used to store the electrical energy generated by the photovoltaic panels and supply the electrical energy to the base station. The support mechanism includes a plurality of supports arranged in a ring array on the outer cylinder. The supports are hinged to the bottom end of the outer cylinder. A plurality of hydraulic rods are hinged to the middle of the outer cylinder. The output ends of the plurality of hydraulic rods are respectively hinged to the portions of the plurality of supports near the outer cylinder. After the mast mechanism is placed horizontally on the support surface, the hydraulic rod extends, thereby causing the support to swing so that the mast mechanism stands up. After the mast mechanism stands up, the middle cylinder and the inner cylinder move upward so that the mast mechanism unfolds.

[0006] Furthermore, it also includes a drive mechanism for driving the mast mechanism to extend after the hydraulic rod has extended.

[0007] Furthermore, the drive mechanism includes a motor, a retractable wheel, and a hydraulic pump. The retractable wheel is used to drive the mast mechanism to unfold, and the hydraulic pump is used to drive the hydraulic rod to extend and retract. The output end of the motor is fixedly connected to a drive shaft, the middle of the receiving wheel is provided with a through hole that is clearance-fitted with the drive shaft, and the hydraulic oil pump is located at the end of the drive shaft. A transmission sleeve is slidably connected to the drive shaft between the receiving wheel and the hydraulic pump. Both ends of the transmission sleeve are provided with anti-slip texture. When the transmission sleeve slides axially on the drive shaft, it can abut against the receiving wheel or the pump shaft of the hydraulic pump, thereby enabling the motor to drive the receiving wheel to rotate or the hydraulic pump to run.

[0008] Furthermore, a first pull rope is fixedly connected to the storage wheel. The first pull rope passes through the side wall of the outer cylinder and protrudes near the upper part of the outer cylinder, and is fixedly connected to the bottom of the middle cylinder. A second pull rope is fixedly connected to the bottom of the outer cylinder. The second pull rope passes through the side wall of the middle cylinder and protrudes near the upper part of the middle cylinder, and is fixedly connected to the bottom of the inner cylinder. When the storage wheel retracts the first pull rope, the first pull rope can lift the middle cylinder upwards, and when the middle cylinder moves upwards, the second pull rope can lift the inner cylinder upwards, thereby causing the mast mechanism to unfold.

[0009] Furthermore, there are multiple first pull ropes and multiple second pull ropes, with the multiple first pull ropes arranged in a circular array on the outer cylinder and the multiple second pull ropes arranged in a circular array on the middle cylinder; A cable collection ring is fixedly connected to the bottom wall of the outer cylinder, and the ends of the multiple first pull ropes pass through the cable collection ring and are stored in the storage wheel.

[0010] Furthermore, the hydraulic pump is connected to a first oil pipe and a second oil pipe. The first oil pipe has multiple branches, which are respectively connected to multiple hydraulic rods. A flow divider valve is provided at the branch portion of the first oil pipe. The end of the second oil pipe is connected to a hydraulic oil tank.

[0011] Furthermore, a piston cylinder is fixedly connected to the bottom wall of the outer cylinder, and a piston rod is slidably connected inside the piston cylinder. A tension spring is connected between one end of the piston rod and the piston cylinder, and a bracket is fixedly connected to the other end of the piston rod. The transmission sleeve is rotatably connected to the bracket, and when the piston rod slides, it can push the transmission sleeve to slide on the drive shaft.

[0012] Furthermore, an active hydraulic cylinder is fixedly connected to the bottom wall of the outer cylinder, the cylinder rod of the active hydraulic cylinder extends beyond the bottom wall of the outer cylinder, and a pipe is connected between the active hydraulic cylinder and the piston cylinder; When the outer cylinder is laid flat, the tension spring pulls the piston rod so that the transmission sleeve is driven and abuts against the pump shaft of the hydraulic pump. When the outer cylinder is erected, pressure is applied to the active cylinder, thereby shortening the active cylinder so that the piston rod drives the transmission sleeve to slide and abut against the receiving wheel.

[0013] Furthermore, the pipeline is equipped with a pull valve, which opens when all of the supports swing to be perpendicular to the side wall of the outer cylinder.

[0014] Furthermore, a sliding plate is slidably connected inside the hydraulic oil tank, the sliding plate is in contact with the inner wall of the hydraulic oil tank, and a pull wire is connected between the upper surface of the sliding plate and the valve stem of the lifting valve; When all of the supports swing to be perpendicular to the outer cylinder sidewall, the hydraulic oil level in the hydraulic oil tank drops, so that the slide can move down to the position where the lifting valve is opened by the pull line.

[0015] The beneficial effects of this invention are analyzed as follows: When deploying a base station, simply place the mast mechanism flat on the desired flat ground location. Then, control multiple hydraulic rods to extend synchronously, causing the supports to unfold. Multiple supports are installed, each with its hinged joint to the outer cylinder at the bottom of the outer cylinder. The length of the support is close to the height of the outer cylinder, allowing the supports to swing relative to the outer cylinder as the hydraulic rods extend. The supports are arranged in a ring around the outside of the outer cylinder, so that any one or two adjacent supports can provide support to the outer cylinder during swinging, causing the outer cylinder to move from a horizontal to an inclined state. Finally, when the multiple supports swing to be perpendicular to the outer cylinder, the entire mast mechanism can be placed vertically. At this point, the multiple supports... The mast mechanism provides overall support to prevent it from tipping over. After the mast is erected, the middle and inner cylinders move upwards, allowing the mast to unfold. Once the middle and inner cylinders reach their target positions, the base station deployment is complete. The photovoltaic panels on the outer walls of the middle and inner cylinders convert sunlight into electricity, which is stored in batteries at the bottom of the outer cylinder, providing power for the base station's operation. The location of the batteries at the bottom of the outer cylinder also lowers the overall center of gravity of the mast mechanism, improving the stability of the base station deployment. Through these features, the base station can be deployed without hoisting or supporting it to ensure it is in an upright position before unfolding, thus saving manpower and resources and improving the deployment efficiency of the base station.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Examples, such as Figures 1-9 As shown, an emergency communication base station includes a mast mechanism 100 and a support mechanism 200. The mast mechanism 100 includes an outer cylinder 110, a middle cylinder 120, and an inner cylinder 130 arranged sequentially from the outside to the inside. Photovoltaic panels are installed on the outer surfaces of the middle cylinder 120 and the inner cylinder 130. A storage battery is installed at the bottom of the outer cylinder 110 to store the electrical energy generated by the photovoltaic panels and supply the electrical energy to the base station. The support mechanism 200 includes a plurality of supports 21 arranged in a ring array on the outer cylinder 110. 0. Support 210 is hinged to the bottom end of outer cylinder 110. Multiple hydraulic rods 220 are hinged to the middle of outer cylinder 110. The output ends of multiple hydraulic rods 220 are respectively hinged to the parts of multiple supports 210 near outer cylinder 110. After mast mechanism 100 is placed horizontally on support surface, hydraulic rods 220 extend, thereby supporting 210 swings to make mast mechanism 100 stand up. After mast mechanism 100 stands up, middle cylinder 120 and inner cylinder 130 move upward to make mast mechanism 100 unfold.

[0020] The mast mechanism 100 serves as the main body of the base station. The base station's antenna is mounted on top of the inner cylinder 130. During base station deployment, the mast mechanism 100 is simply placed flat on the desired location. Then, multiple hydraulic rods 220 are simultaneously extended, causing the support 210 to unfold. Multiple supports 210 are provided, with each support 210's hinge point to the outer cylinder 110 located at the bottom of the outer cylinder 110. Furthermore, the length of the support 210 is close to the height of the outer cylinder 110, thus enabling the support 210 to be driven when the hydraulic rods 220 extend. The mast mechanism 100 swings relative to the outer cylinder 110, and multiple supports 210 are arranged in a ring outside the outer cylinder 110, so that any one or two adjacent supports 210 can support the outer cylinder 110 when swinging, so that the outer cylinder 110 moves from a horizontal state to an inclined state, and when the multiple supports 210 finally swing to be perpendicular to the outer cylinder 110, the mast mechanism 100 can be placed vertically as a whole. At this time, the multiple supports 210 provide overall support for the mast mechanism 100 to prevent the mast mechanism 100 from tipping over. After the mast mechanism 100 is erected, the middle cylinder 120 and the inner cylinder 130 move upward, thereby causing the mast mechanism 100 to unfold. After the middle cylinder 120 and the inner cylinder 130 move upward to the target position, the base station deployment is completed. The photovoltaic panels on the outer walls of the middle cylinder 120 and the inner cylinder 130 convert light energy into electrical energy and store it in the battery at the bottom of the outer cylinder 110, providing power for the operation of the base station. The battery is located at the bottom of the outer cylinder 110, which also causes the overall center of gravity of the mast mechanism 100 to shift downward, improving the stability of the base station deployment. The above setup eliminates the need for hoisting or support to ensure the base station is vertical before deployment, thus saving manpower and resources and improving deployment efficiency.

[0021] It also includes a drive mechanism 300, which is used to drive the hydraulic rod 220 to extend and then deploy the mast mechanism 100.

[0022] The drive mechanism 300 is used to drive the mast mechanism 100 to stand up and unfold. The drive mechanism 300 first drives the hydraulic rod 220 to extend, so that the support 210 drives the mast mechanism 100 to stand up while unfolding. Only after the mast mechanism 100 is stood up will the mast mechanism 100 be driven to unfold.

[0023] The drive mechanism 300 includes a motor 310, a retractable wheel 330, and a hydraulic pump 340. The retractable wheel 330 is used to drive the mast mechanism 100 to unfold, and the hydraulic pump 340 is used to drive the hydraulic rod 220 to extend and retract. The output end of the motor 310 is fixedly connected to the drive shaft 320. The retractable wheel 330 has a through hole in the middle that is clearance-fitted with the drive shaft 320. The hydraulic pump 340 is located at the end of the drive shaft 320. A transmission sleeve 321 is slidably connected to the drive shaft 320 between the retractable wheel 330 and the hydraulic pump 340. Both ends of the transmission sleeve 321 are provided with anti-slip textures. When the transmission sleeve 321 slides axially on the drive shaft 320, it can abut against the pump shaft of the retractable wheel 330 or the hydraulic pump 340, thereby enabling the motor 310 to drive the retractable wheel 330 to rotate or the hydraulic pump 340 to run.

[0024] The motor 310 is installed on the inner bottom wall of the outer cylinder 110. Its drive shaft 320 is used to drive the rotation of the storage wheel 330 and the operation of the hydraulic oil pump 340. The transmission sleeve 321 can slide on the drive shaft 320, thereby changing the driving target of the motor 310. In the initial state, the end of the transmission sleeve 321 abuts against the pump shaft of the hydraulic oil pump 340, so that the operation of the motor 310 can drive the operation of the hydraulic oil pump 340. After the support 210 is unfolded, the transmission sleeve 321 slides so that its other end abuts against the storage wheel 330. At this time, the operation of the motor 310 can drive the storage wheel 330 to rotate, thereby causing the mast mechanism 100 to unfold. The sequential operation of the hydraulic oil pump 340 and the storage wheel 330 ensures that the mast mechanism 100 will unfold only after the outer cylinder 110 is erected. The transmission sleeve 321 can not only enable the hydraulic oil pump 340 or the receiving wheel 330 to operate through the anti-slip texture, but also has mutually cooperating protrusions, grooves, or blocks and slots on the end of the transmission sleeve 321, the pump shaft end of the hydraulic oil pump 340, and the side of the receiving wheel 330 to ensure the transmission of power.

[0025] A first pull rope 332 is fixedly connected to the storage wheel 330. The first pull rope 332 passes through the side wall of the outer cylinder 110 and protrudes near the upper part of the outer cylinder 110, and is fixedly connected to the bottom of the middle cylinder 120. A second pull rope 333 is fixedly connected to the bottom of the outer cylinder 110. The second pull rope 333 passes through the side wall of the middle cylinder 120 and protrudes near the upper part of the middle cylinder 120, and is fixedly connected to the bottom of the inner cylinder 130. When the storage wheel 330 winds up the first pull rope 332, the first pull rope 332 can lift the middle cylinder 120 upward. When the middle cylinder 120 moves upward, the second pull rope 333 can lift the inner cylinder 130 upward, thereby causing the mast mechanism 100 to unfold.

[0026] One end of the first pull rope 332 is wrapped around the storage wheel 330, and the other end is fixedly connected to the bottom of the middle cylinder 120. The middle part of the first pull rope 332 is n-shaped, with one vertical section inside the side wall of the outer cylinder 110 and the other vertical section outside the side wall of the outer cylinder 110. When the storage wheel 330 rotates and stores the first pull rope 332, the top of the n-shaped first pull rope 332 forms a fulcrum with the contact point with the outer cylinder 110, and the vertical section outside the side wall of the outer cylinder 110 shortens, thereby lifting the middle cylinder 120 and causing the middle cylinder 120 to move upward relative to the outer cylinder 110. The second pull rope 333 is also n-shaped, with one vertical section inside the side wall of the middle cylinder 120 and the other vertical section outside the side wall of the middle cylinder 120. One end of the second pull rope 333 is fixedly connected to the bottom wall of the outer cylinder 110, and the other end is fixedly connected to the bottom of the inner cylinder 130. When the middle cylinder 120 moves upward, the second pull rope 333 pulls the inner cylinder 130 upward at the contact point between the top of its n-shape and the middle cylinder 120. At this time, the part of the second pull rope 333 outside the side wall of the middle cylinder 120 is shortened, so that the inner cylinder 130 has a superimposed movement of moving upward with the middle cylinder 120 and moving upward relative to the middle cylinder 120, thereby enabling the mast mechanism 100 to be quickly deployed. When the mast mechanism 100 is retracted, the retracting wheel 330 is controlled to rotate in the opposite direction, so that the first pull rope 332 is released, and the middle cylinder 120 moves downward under gravity. At the same time, the inner cylinder 130 also moves downward under gravity, and finally the mast mechanism 100 is retracted.

[0027] Multiple first pull ropes 332 and multiple second pull ropes 333 are provided, and the multiple first pull ropes 332 are arranged in a ring array on the outer cylinder 110, and the multiple second pull ropes 333 are arranged in a ring array on the middle cylinder 120; a cable collection ring 331 is fixedly connected to the bottom wall of the outer cylinder 110, and the ends of the multiple first pull ropes 332 pass through the cable collection ring 331 and are stored in the storage wheel 330.

[0028] Multiple first pull ropes 332 and second pull ropes 333 are provided to ensure that the pulling force on the middle cylinder 120 and inner cylinder 130 can be balanced when they move upward. The setting of the wire gathering ring 331 allows multiple first pull ropes 332 to be gathered into a bundle, ensuring that multiple first pull ropes 332 can be stably wound up by the storage wheel 330.

[0029] The hydraulic oil pump 340 is connected to a first oil pipe 341 and a second oil pipe 342. The first oil pipe 341 has multiple branches, which are connected to multiple hydraulic rods 220 respectively. A flow divider valve is provided at the branch part of the first oil pipe 341. The end of the second oil pipe 342 is connected to a hydraulic oil tank 350.

[0030] When the hydraulic pump 340 is running, it can transfer the hydraulic oil between the hydraulic oil tank 350 and the hydraulic rod 220. By controlling the forward and reverse rotation of the hydraulic pump 340, the hydraulic rod 220 can be extended or shortened. A diversion valve is set at the junction of the first oil pipe 341 and multiple branches to make the amount of hydraulic oil flowing through each hydraulic rod 220 equal, thereby ensuring that the extension and retraction of each hydraulic rod 220 is equal, ensuring that the support 210 can be extended or retracted synchronously, and ensuring that it can stably support the mast mechanism 100.

[0031] A piston cylinder 360 is fixedly connected to the bottom wall of the outer cylinder 110. A piston rod 361 is slidably connected inside the piston cylinder 360. A tension spring 363 is connected between one end of the piston rod 361 and the piston cylinder 360. A bracket 362 is fixedly connected to the other end of the piston rod 361. A transmission sleeve 321 is rotatably connected to the bracket 362. When the piston rod 361 slides, it can push the transmission sleeve 321 to slide on the drive shaft 320.

[0032] The piston rod 361 can slide inside the piston cylinder 360, and when the piston rod 361 slides, it can drive the transmission sleeve 321 to slide through the bracket 362, thereby switching the output direction of the motor 310.

[0033] An active hydraulic cylinder 370 is fixedly connected to the bottom wall of the outer cylinder 110. The cylinder rod of the active hydraulic cylinder 370 extends beyond the bottom wall of the outer cylinder 110. A pipe 371 connects the active hydraulic cylinder 370 and the piston cylinder 360. When the outer cylinder 110 is laid flat, the tension spring 363 pulls the piston rod 361 so that the transmission sleeve 321 is driven and abuts against the pump shaft of the hydraulic pump 340. When the outer cylinder 110 is erected, pressure is applied to the active hydraulic cylinder 370, thereby shortening the active hydraulic cylinder 370 so that the piston rod 361 drives the transmission sleeve 321 to slide and abut against the receiving wheel 330.

[0034] In the initial state, the mast mechanism 100 is placed flat on the support surface. At this time, the active cylinder 370 is not under pressure from the mast mechanism 100. Therefore, in this state, the tension spring 363 pulls the piston rod 361 to prevent it from sliding outward from the piston cylinder 360. At this time, the piston rod 361 drives one end of the transmission sleeve 321 through the bracket 362 to connect with the pump shaft of the hydraulic pump 340. At this time, the control motor 310 runs, thereby driving the hydraulic pump 340 to unfold the support 210. After the support 210 unfolds, the mast mechanism 100 stands up. At this time, the active cylinder 370 is compressed and drives the piston rod 361 to slide away from the piston cylinder 360, thereby driving the other end of the transmission sleeve 321 to connect with the storage wheel 330. At this time, the motor 310 drives the storage wheel 330 to rotate, thereby storing the first pull rope 332, and thus unfolding the mast mechanism 100.

[0035] A lifting valve 372 is installed on the pipe 371. When multiple supports 210 swing to be perpendicular to the side wall of the outer cylinder 110, the lifting valve 372 opens.

[0036] The lifting valve 372 will only open when the support 210 is fully extended to be perpendicular to the side wall of the outer cylinder 110, ensuring that the mast mechanism 100 can be stably supported before it is extended.

[0037] A sliding plate 351 is slidably connected inside the hydraulic oil tank 350. The sliding plate 351 is in contact with the inner wall of the hydraulic oil tank 350. A pull line 352 is connected between the upper surface of the sliding plate 351 and the valve stem of the lifting valve 372. When multiple supports 210 swing to be perpendicular to the side wall of the outer cylinder 110, the hydraulic oil level in the hydraulic oil tank 350 drops, so that the sliding plate 351 can move down to the position where the lifting valve 372 is opened by pulling the pull line 352.

[0038] The pull cable 352 has sufficient length so that when the hydraulic pump 340 draws hydraulic oil from the hydraulic oil tank 350, causing the hydraulic rod 220 to extend, the slide plate 351 simultaneously moves downward relative to the hydraulic oil tank 350. When the hydraulic rod 220 extends to the point where the support 210 is perpendicular to the side wall of the outer cylinder 110, the slide plate 351 can just move down to pull the valve stem of the lifting valve 372 through the pull cable 352 to open it. At this time, the hydraulic oil output in the active cylinder 370 is unobstructed, and the gravity of the mast mechanism 100 is applied to the active cylinder 370, causing it to shorten. Thus, the hydraulic oil in the active cylinder 370 is transferred to the piston cylinder 360, causing the piston rod 361 to extend. At this time, the transmission sleeve 321 moves and connects with the storage wheel 330, so that the subsequent motor 310 can drive the mast mechanism 100 to unfold. Since hydraulic oil is not easily compressed, the amount of hydraulic oil required for the hydraulic rod 220 to extend when the support 210 swings to be perpendicular to the outer cylinder 110 is determined, which also determines the amount of sliding of the slide plate 351. Furthermore, the pull cable 352 does not have elasticity, thus ensuring that after the support 210 is fully extended, the power of the motor 310 will immediately switch to drive the mast mechanism 100 to extend. When the mast mechanism 100 is being retracted, since the outer cylinder 110 is in an upright state, the active cylinder 370 is in a shortened state. At this time, the motor 310 can still drive the retraction wheel 330 to rotate. The motor 310 is then turned around, which releases the first pull rope 332. The mast mechanism 100 is then retracted. When the mast mechanism 100 is about to be fully retracted, the mast mechanism 100 is pushed to tilt slightly, or the entire mast mechanism 100 is lifted up so that the active cylinder 370 is not under pressure. At this time, the tension spring 363 pulls the piston rod 361 to reset, which drives the hydraulic pump 340 to reverse, causing the hydraulic rod 220 to shorten, thus retracting the support 210. It should be noted that the hydraulic pump 340 is a gear pump, which means that when the hydraulic pump 340 is turned around, the flow direction of the hydraulic oil will also be reversed.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The output end of the motor (310) is fixedly connected to the drive shaft (320), the middle part of the receiving wheel (330) is provided with a through hole that is clearance-fitted with the drive shaft (320), and the hydraulic oil pump (340) is located at the end of the drive shaft (320). A transmission sleeve (321) is keyed and slidably connected on the drive shaft (320) between the receiving wheel (330) and the hydraulic oil pump (340). Both ends of the transmission sleeve (321) are provided with anti-slip texture. When the transmission sleeve (321) slides axially on the drive shaft (320), it can abut against the receiving wheel (330) or the pump shaft of the hydraulic oil pump (340), thereby enabling the motor (310) to drive the receiving wheel (330) to rotate or the hydraulic oil pump (340) to run. A first pull rope (332) is fixedly connected to the storage wheel (330). The first pull rope (332) passes through the side wall of the outer cylinder (110) and protrudes near the upper part of the outer cylinder (110), and is fixedly connected to the bottom of the middle cylinder (120). The bottom of the outer cylinder (110) is fixedly connected to a second pull rope (333), which passes through the side wall of the middle cylinder (120) and protrudes near the upper part of the middle cylinder (120), and is fixedly connected to the bottom of the inner cylinder (130). When the storage wheel (330) winds up the first pull rope (332), the first pull rope (332) can lift the middle cylinder (120) upward, and when the middle cylinder (120) moves upward, the inner cylinder (130) can be lifted upward by the second pull rope (333), thereby causing the mast mechanism (100) to unfold.

The bottom wall of the outer cylinder (110) is fixedly connected to a cable gathering ring (331), and the ends of the multiple first pull ropes (332) pass through the cable gathering ring (331) and are stored in the storage wheel (330).

3. The emergency communication base station according to claim 1, characterized in that: The hydraulic pump (340) is connected to a first oil pipe (341) and a second oil pipe (342). The first oil pipe (341) has multiple branches, which are respectively connected to multiple hydraulic rods (220). A flow divider valve is provided at the branch of the first oil pipe (341). The end of the second oil pipe (342) is connected to a hydraulic oil tank (350).

4. The emergency communication base station according to claim 3, characterized in that: A piston cylinder (360) is fixedly connected to the bottom wall of the outer cylinder (110). A piston rod (361) is slidably connected inside the piston cylinder (360). A tension spring (363) is connected between one end of the piston rod (361) and the piston cylinder (360). A bracket (362) is fixedly connected to the other end of the piston rod (361). The transmission sleeve (321) is rotatably connected to the bracket (362). When the piston rod (361) slides, it can push the transmission sleeve (321) to slide on the drive shaft (320).

5. The emergency communication base station according to claim 4, characterized in that: An active hydraulic cylinder (370) is fixedly connected to the bottom wall of the outer cylinder (110). The cylinder rod of the active hydraulic cylinder (370) extends beyond the bottom wall of the outer cylinder (110). A pipe (371) connects the active hydraulic cylinder (370) and the piston cylinder (360). When the outer cylinder (110) is laid flat, the tension spring (363) pulls the piston rod (361) so that the transmission sleeve (321) is driven and abuts against the pump shaft of the hydraulic pump (340). When the outer cylinder (110) is erected, it can apply pressure to the active cylinder (370), thereby shortening the active cylinder (370) so that the piston rod (361) drives the transmission sleeve (321) to slide and abut against the receiving wheel (330).

6. The emergency communication base station according to claim 5, characterized in that: A lifting valve (372) is provided on the pipe (371). When all the supports (210) swing to be perpendicular to the side wall of the outer cylinder (110), the lifting valve (372) opens.

7. The emergency communication base station according to claim 6, characterized in that: A sliding plate (351) is slidably connected inside the hydraulic oil tank (350). The sliding plate (351) is in contact with the inner wall of the hydraulic oil tank (350). A pull wire (352) is connected between the upper surface of the sliding plate (351) and the valve stem of the lifting valve (372). When all of the supports (210) swing to be perpendicular to the side wall of the outer cylinder (110), the hydraulic oil level in the hydraulic oil tank (350) drops, so that the slide plate (351) can move down to the position where the pull valve (372) is opened by the pull line (352).
