Description

Technical Field

[0001] This invention relates to the field of mobile communication vehicle technology, and more specifically to a mobile communication vehicle. Background Technology

[0002] A mobile communication vehicle is a special emergency support vehicle equipped with communication equipment. It can quickly build temporary communication networks in specific locations, acting like a "mobile signal tower." The core function of a mobile communication vehicle is to provide emergency communication support to areas where conventional network coverage is insufficient, there is temporary congestion, or the network is interrupted due to disasters.

[0003] In the field of mobile communication vehicle technology, to ensure emergency communication and temporary network coverage, it is often necessary to quickly deploy vehicle-mounted antennas in complex environments. In existing technologies, mobile communication vehicle antennas are mostly directly fixed to the roof or vertically raised using simple lifting rods. However, when deployed in complex terrains and obstacles such as dense urban blocks, jungles, or post-earthquake ruins, this antenna system with its low initial position and single deployment mode has significant limitations: when the antenna can only be raised and lowered vertically, its radiated signal is easily blocked and reflected at low altitudes by nearby building debris, billboards, dense tree canopies, or other vehicles, forming severe signal shadow areas and multipath interference, leading to communication blind spots or a sharp drop in quality. This not only limits the expansion of the effective coverage area but may also delay rescue command in the critical initial stage of emergency communication due to the inability to quickly establish a stable and reliable signal link. Therefore, how to enable the antenna to actively and quickly escape the complex electromagnetic environment and physical obstructions near the vehicle roof in the initial deployment stage, creating a better initial radiation condition, has become a key technical problem for improving the initial communication capability and communication efficiency of mobile communication vehicles in complex scenarios. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a mobile communication vehicle to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A mobile communication vehicle includes a vehicle body, a mounting plate fixedly installed on the top surface of the vehicle body's compartment, two guardrails fixedly installed on the top surface of the mounting plate, a ladder fixedly installed at the rear of the vehicle body, the ladder being fixedly installed to the mounting plate, and a mushroom-shaped antenna disposed on the top surface of the mounting plate; an anti-obstruction component disposed on the top surface of the mounting plate, used to prevent the signal of the mobile communication vehicle body from being obstructed due to angle or height effects, the anti-obstruction component including: a support shell fixedly installed on the top surface of the mounting plate, an operating frame fixedly installed on the top surface of the mounting plate, and a drive motor fixedly installed on one side of the operating frame. A transmission column is movably sleeved inside the drive motor, and a first gear is fixedly sleeved on the outer circular wall of the transmission column. A central column is movably sleeved inside the operating frame and extends to the outside of the operating frame. A second gear is fixedly sleeved on the outer circular wall of the central column, and the second gear meshes with the first gear. The drive shaft of the drive motor is fixedly installed to the transmission column. An extension shell is provided on one side of the support shell, and the central column is fixedly installed to the extension shell. One end of the extension shell is provided with a lifting component for further extending the mushroom-shaped antenna. The top surface of the mounting plate is provided with an anti-interference component for dust reduction around the mobile communication vehicle body.

[0007] By adopting the above technical solution, and through the central column, when the operator uses the mushroom-shaped antenna, the drive motor first rotates, and the drive shaft of the drive motor rotates, which in turn drives the transmission column and the first gear to rotate. During the rotation of the first gear, it meshes and drives the second gear and the central column to rotate. At this time, the rotation of the central column drives the extension shell to rotate. Since the initial state of the extension shell is close to the top surface of the mobile communication vehicle body, and the mushroom-shaped antenna is also close to the top surface of the mobile communication vehicle body, when the central column drives the extension shell to rotate, the central column will gradually rotate the extension shell and the mushroom-shaped antenna to a vertical state. Then, the extension shell and the mobile communication vehicle body are in a perpendicular state. At this time, the top of the extension shell and the position of the mushroom-shaped antenna will be raised, so that the mushroom-shaped antenna can avoid the complex environment and rise to a higher position, so as to avoid the obstruction of the mushroom-shaped antenna signal by the surrounding environment.

[0008] Preferably, the lifting assembly includes: a storage slot, the storage slot being formed at one end of the extension shell, an extension rod slidably connected inside the storage slot, diagonal braces fixedly installed on both sides of the extension rod, a mushroom-shaped antenna fixedly installed between the two diagonal braces, a first sprocket fixedly sleeved on the outer circular wall of the central column, a rotating column provided on one side of the support shell, the rotating column penetrating the support shell, a second sprocket fixedly installed at one end of the rotating column, a chain meshing with the outer circular walls of the first sprocket and the second sprocket, a push rod fixedly sleeved on the outer circular wall of the rotating column, a push hole formed on the top surface of the extension shell, the push hole communicating with the storage slot, a resistance groove formed on the top surface of the extension rod, and the push rod passing through the push hole and movably engaging with the resistance groove.

[0009] By adopting the above technical solution, the push rod, when the transmission column and the first gear rotate, meshes and drives the second gear and the central column to rotate. In turn, the rotation of the central column drives the first sprocket to rotate. The rotation of the first sprocket drives the second sprocket to rotate via the chain. The rotation of the second sprocket drives the rotating column and the push rod to rotate. When the transmission column, the first gear, the central column, and the first sprocket rotate, the first sprocket drives the second sprocket and the rotating column to rotate synchronously via the chain. As a result, the extension shell and the push rod will rotate synchronously to an upright state. During this process, the positions of the push rod and the extension shell gradually become parallel, and the push rod generates thrust against the inner wall of the resistance groove. The push rod then pushes the extension rod to move the diagonal brace and the mushroom-shaped antenna. Afterward, the extension rod is pushed out of the storage groove by the push rod, thereby extending the height of the mushroom-shaped antenna.

[0010] Preferably, the bottom surface of the push rod is provided with an installation groove, a fixed column is fixedly installed inside the installation groove, a rolling column is movably sleeved on the outer circular wall of the fixed column, and the rolling column is slidably connected to the resistance groove.

[0011] By adopting the above technical solution, when the push rod abuts against the inner wall of the resistance groove and pushes the extension rod to move, the friction position between the rolling column and the inner wall of the resistance groove will also change as the position of the extension shell and the push rod changes. At this time, through the contact between the rolling column and the inner wall of the resistance groove, the rolling column can be rotated around the fixed column, so as to reduce the frictional resistance generated when the push rod changes position in the resistance groove.

[0012] Preferably, an adjusting bracket and a limiting bracket are fixedly installed on the top surface of the mounting plate. A fixing groove is provided on one side of the adjusting bracket, and a stepper motor is fixedly installed inside the fixing groove. A threaded rod is provided inside the adjusting bracket, and the threaded rod is fixedly installed to the drive shaft of the stepper motor. A slide table is slidably connected inside the adjusting bracket, and the slide table is threadedly connected to the threaded rod. Two stabilizing rods are provided on the top surface of the mounting plate, and a baffle is fixedly installed between the two stabilizing rods. The slide table is fixedly installed to the stabilizing rods. A guide rod is fixedly installed inside the limiting bracket, and the guide rod is movably sleeved with the stabilizing rod. The stabilizing rod is slidably connected to the limiting bracket.

[0013] By adopting the above technical solution, and with the baffle installed, when the mushroom-shaped antenna is not in use and is attached to the top surface of the mobile communication vehicle body, the baffle will block the top surface of the mushroom-shaped antenna, which can protect and shield the mushroom-shaped antenna in rainy or snowy weather. When the mushroom-shaped antenna is raised for use, a stepper motor is used. The drive shaft of the stepper motor rotates, which drives the threaded rod to rotate, thereby allowing the slide to move linearly along the inside of the adjustment frame. Then, the slide will drive the stabilizing rod and the baffle to move forward, thereby removing the baffle from the top of the mushroom-shaped antenna, so that the mushroom-shaped antenna is between the two stabilizing rods, allowing the mushroom-shaped antenna to smoothly rotate to a higher position with the extension shell.

[0014] Preferably, the anti-interference component includes: a water storage tank, which is fixedly installed on the top surface of the mounting plate; a diversion pipe is fixedly installed on the top surface of the water storage tank; a water pump is fixedly installed on the top surface of the mounting plate; a suction pipe is fixedly installed on the outer circular wall of the diversion pipe and extends into the interior of the diversion pipe; the suction pipe is fixedly sleeved with the outlet of the water pump; an inlet pipe is fixedly installed on one side of the water storage tank and extends into the interior of the water storage tank; the inlet pipe is fixedly sleeved with the inlet of the water pump; a plurality of limiting holes are opened on the outer circular wall of the diversion pipe; a spray pipe is fixedly sleeved on the inner circular wall of the limiting holes; and a nozzle is fixedly sleeved on the inner circular wall of the spray pipe.

[0015] By adopting the above technical solution, water is injected into the water tank through the nozzle, and then the water pump draws water from the water tank through the inlet pipe and injects it into the distribution pipe through the outlet pipe. The water then enters the spray pipe and is atomized and sprayed out through the nozzle, which facilitates dust reduction in the environment around the mobile communication vehicle and prevents the mushroom-shaped antenna from interfering in environments with a lot of sand and dust.

[0016] Preferably, a collection box is fixedly installed on the top surface of the mounting plate. The collection box is located between the water storage tanks. Several water flow holes are opened on both sides of the interior of the water storage tanks. Overflow holes are opened on both sides of the collection box. A collection pipe is fixedly sleeved on the inner circular wall of the overflow hole. The collection pipe is fixedly sleeved with the water flow hole.

[0017] By adopting the above technical solution, the rainwater will be collected inside the collection box when it rains. Then, the rainwater inside the collection box will enter the overflow hole through the collection box, thus facilitating the collection of rainwater.

[0018] Preferably, a filter plate is fixedly installed inside the collection box, and the top surface of the filter plate has a plurality of filter holes.

[0019] By adopting the above technical solution, and through the filter holes, when rainwater enters the collection box, it will pass through the filter plate and filter holes, and then be blocked by the filter holes and filter plate, thus facilitating the filtration of garbage such as leaves in the rainwater.

[0020] Preferably, a warning light is fixedly installed on the top surface of the mobile communication vehicle body.

[0021] By adopting the above technical solution, and by setting up a warning light, the warning light will turn red when the mobile communication vehicle is in operation, thereby making it easier to remind people around.

[0022] In summary, the present invention has the following main beneficial effects:

[0023] 1. The present invention uses a central column. When the system is started, the drive motor works and drives the first gear to rotate through the transmission column. The first gear meshes with the second gear, driving the central column and the extension shell fixed on it to rotate as a whole, thereby smoothly lifting the mushroom-shaped antenna placed on the roof of the vehicle from a horizontal state to a vertical state. Through the gear transmission mechanism, the mushroom-shaped antenna is rotated from the top storage state of the mobile communication vehicle body to the vertical working state, so that the mushroom-shaped antenna is freed from the complex electromagnetic environment and physical obstruction near the roof of the vehicle, laying the foundation for subsequent height extension.

[0024] 2. This invention utilizes a push rod, where the rotation of the central column simultaneously drives the first sprocket to rotate. Power is transmitted via a chain to the second sprocket and the rotating column, causing the push rod to rotate synchronously. During the lifting process, the top of the push rod always rests against the inner wall of the resistance groove at the bottom of the extension rod, generating a continuous thrust that smoothly pushes the extension rod and its top mushroom-shaped antenna out of the storage slot. During the lifting process, the mushroom-shaped antenna is simultaneously pushed upward through chain drive and linkage mechanism. Based on vertical lifting, the actual installation height of the mushroom-shaped antenna is further physically increased, maximizing signal coverage and quality.

[0025] 3. In this invention, when the vehicle is in the retracted roof position, a baffle covers the roof. When it needs to be raised, a stepper motor drives a threaded rod to rotate, causing the slide, the connected stabilizing rod, and the baffle to move laterally as a whole, thereby removing the baffle from above to make way for rotation and provide physical protection. The baffle also moves automatically during operation, effectively preventing rain, snow, dust, and other substances from corroding the vehicle in the retracted state. The fully automatic removal process requires no manual intervention, ensuring rapid deployment.

[0026] 4. The present invention, through the setting of nozzles, water tank, water pump and atomizing nozzle, after starting, the water pump draws water from the water tank, delivers it to the nozzle through the pipeline and sprays it out in the form of water mist, forming fine water mist around the mobile communication vehicle body, effectively settling sand and dust particles in the air, reducing the attenuation effect of sand and dust on the signal, and reducing the adhesion of sand and dust on the surface of the equipment.

[0027] 5. This invention features a collection box and filter holes. The rainwater collection box is located on the roof of the vehicle. The collected rainwater is initially filtered by a filter plate with filter holes to remove debris such as leaves. Then, it is introduced into a water storage container through an overflow hole to provide a supplementary water source for the dust suppression system. This enhances the system's ability to operate for extended periods in water-scarce environments and reflects an energy-saving design. Attached Figure Description

Detailed Implementation

[0040] 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.

[0041] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7A mobile communication vehicle includes a vehicle body 1. A mounting plate 2 is fixedly installed on the top surface of the vehicle body 1. Two guardrails 3 are fixedly installed on the top surface of the mounting plate 2. A ladder 4 is fixedly installed at the rear of the vehicle body 1 and is fixedly installed to the mounting plate 2. A mushroom-shaped antenna 5 is provided on the top surface of the mounting plate 2. An anti-obstruction component is provided on the top surface of the mounting plate 2 to prevent the signal of the mobile communication vehicle body 1 from being obstructed due to angle or height. The anti-obstruction component includes a support shell 6, which is fixedly installed on the top surface of the mounting plate 2. An operating mechanism is fixedly installed on the top surface of the mounting plate 2. The frame 7 has a drive motor 8 fixedly installed on one side. The drive motor 8 has a transmission column 9 movably sleeved inside. The outer circular wall of the transmission column 9 is fixedly sleeved with a first gear 10. The operation frame 7 has a central column 11 movably sleeved inside and extending to the outside of the operation frame 7. The outer circular wall of the central column 11 is fixedly sleeved with a second gear 12. The second gear 12 meshes with the first gear 10. The drive shaft of the drive motor 8 is fixedly installed with the transmission column 9. The support shell 6 has an extension shell 13 on one side. The central column 11 is fixedly installed with the extension shell 13. The mobile communication vehicle body 1 has a warning light 50 fixedly installed on the top surface.

[0042] When the system is started via the central column 11, the drive motor 8 works and drives the first gear 10 to rotate via the transmission column 9. The first gear 10 meshes with the second gear 12, driving the central column 11 and the extension shell 13 fixed on it to rotate as a whole, thereby smoothly lifting the mushroom-shaped antenna 5, which is placed flat on the roof of the vehicle, from a horizontal state to a vertical state. The initial lifting and attitude adjustment of the mushroom-shaped antenna 5, through the gear transmission mechanism, rotates the mushroom-shaped antenna 5 from the roof storage state to the vertical working state.

[0043] Based on the above embodiments, refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8One end of the extension shell 13 is provided with a lifting component for further extending the mushroom-shaped antenna 5. The lifting component includes a storage slot 14, which is opened at one end of the extension shell 13. An extension rod 15 is slidably connected inside the storage slot 14. Diagonal braces 16 are fixedly installed on both sides of the extension rod 15. The mushroom-shaped antenna 5 is fixedly installed between the two diagonal braces 16. A first sprocket 17 is fixedly sleeved on the outer circular wall of the central column 11. A rotating column 20 is provided on one side of the support shell 6. The rotating column 20 penetrates the support shell 6. A second sprocket 19 is fixedly installed at one end of the rotating column 20. A chain 18 is meshed with the outer circular wall of the first sprocket 17 and the second sprocket 19. A push rod 21 is fixedly sleeved on the outer circular wall of the rotating column 20. A push hole 22 is opened on the top surface of the extension shell 13. The push hole 22 is connected to the storage slot 14. A resistance groove 23 is opened on the top surface of the extension rod 15. The push rod 21 passes through the push hole 22 and is movably engaged with the resistance groove 23.

[0044] The bottom surface of the push rod 21 is provided with an installation groove 24. A fixed column 25 is fixedly installed inside the installation groove 24. A rolling column 26 is movably sleeved on the outer circular wall of the fixed column 25. The rolling column 26 is slidably connected to the resistance groove 23.

[0045] The rotation of the central column 11 via the push rod 21 simultaneously drives the first sprocket 17 to rotate. The power is transmitted to the second sprocket 19 and the rotating column 20 via the chain 18, thereby causing the push rod 21 to rotate synchronously. During the lifting process, the top of the push rod 21 always abuts against the inner wall of the resistance groove 23 at the bottom of the extension rod 15, generating a continuous thrust to smoothly push the extension rod 15 and its top mushroom-shaped antenna 5 out of the storage groove 14. The secondary extension of the height of the mushroom-shaped antenna 5 is achieved by simultaneously pushing the main body of the mushroom-shaped antenna 5 upward through the chain drive and linkage mechanism during the lifting process. As the push rod 21 moves along the resistance groove 23 and changes its angle of action, the rolling column 26 installed at the top of the push rod will roll on the inner wall of the resistance groove, reducing transmission friction and converting sliding friction into rolling friction.

[0046] Based on the above embodiments, refer to Figure 1 , Figure 4 and Figure 9The top surface of the mounting plate 2 is fixedly equipped with an adjustment frame 27 and a limit frame 28. The adjustment frame 27 has a fixing groove 31 on one side inside. A stepper motor 32 is fixedly installed inside the fixing groove 31. A threaded rod 33 is provided inside the adjustment frame 27. The threaded rod 33 is fixedly installed with the drive shaft of the stepper motor 32. A slide table 34 is slidably connected inside the adjustment frame 27. The slide table 34 is threadedly connected with the threaded rod 33. The top surface of the mounting plate 2 is equipped with two stabilizing rods 29. A baffle 30 is fixedly installed between the two stabilizing rods 29. The slide table 34 is fixedly installed with the stabilizing rods 29. A guide rod 35 is fixedly installed inside the limit frame 28. The guide rod 35 is movably sleeved with the stabilizing rod 29. The stabilizing rod 29 is slidably connected with the limit frame 28.

[0047] When the antenna is in the retracted state on the roof, a baffle 30 covers it. When the antenna needs to be raised, a stepper motor 32 drives the threaded rod 33 to rotate, which in turn moves the slide 34, the stabilizer 29 connected to it, and the baffle 30 laterally as a whole, thereby moving the baffle 30 away from the mushroom-shaped antenna 5 to make way for the rotation of the mushroom-shaped antenna 5. The baffle 30 provides physical protection for the mushroom-shaped antenna 5 in the retracted state and makes way for it during operation, and automatically moves away during operation.

[0048] Based on the above embodiments, refer to Figure 1 , Figure 4 , Figure 10 and Figure 11 The top surface of the mounting plate 2 is provided with an anti-interference component for dust suppression around the mobile communication vehicle body 1. The anti-interference component includes a water tank 36, which is fixedly installed on the top surface of the mounting plate 2. A diversion pipe 37 is fixedly installed on the top surface of the water tank 36. A water pump 38 is fixedly installed on the top surface of the mounting plate 2. A water suction pipe 39 is fixedly installed on the outer circular wall of the diversion pipe 37 and extends into the interior of the diversion pipe 37. The water suction pipe 39 is fixedly sleeved with the outlet of the water pump 38. A water inlet pipe 40 is fixedly installed on one side of the water tank 36 and extends into the interior of the water tank 36. The water inlet pipe 40 is fixedly sleeved with the inlet of the water pump 38. Several limiting holes 43 are opened on the outer circular wall of the diversion pipe 37. A spray pipe 41 is fixedly sleeved on the inner circular wall of the limiting hole 43. A nozzle 42 is fixedly sleeved on the inner circular wall of the spray pipe 41.

[0049] A collection box 44 is fixedly installed on the top surface of the mounting plate 2. The collection box 44 is located between the water storage tanks 36. Several water flow holes 48 are opened on both sides of the interior of the water storage tank 36. Overflow holes 46 are opened on both sides of the collection box 44. A collection pipe 47 is fixedly sleeved on the inner circular wall of the overflow hole 46. The collection pipe 47 is fixedly sleeved with the water flow hole 48. A filter plate 45 is fixedly installed inside the collection box 44. Several filter holes 49 are opened on the top surface of the filter plate 45.

[0050] Water is injected into the water tank 36 through the nozzle 42, and then pumped out through the water inlet pipe 40 and injected into the diversion pipe 37 through the water outlet pipe 39. The water then enters the spray pipe 41 and is atomized and sprayed out through the nozzle 42, forming a fine water mist around the mobile communication vehicle body 1. This facilitates dust suppression in the surrounding environment of the mobile communication vehicle body 1 and prevents the mushroom-shaped antenna 5 from interfering in environments with sand and dust.

[0051] With the collection box 44 and filter hole 49, the roof is equipped with a rainwater collection box 44. The collected rainwater passes through the filter plate 45 with filter hole 49 to initially filter out debris such as leaves, and then enters the water storage container through the overflow hole 46 to realize rainwater collection and primary filtration, automatically collecting and initially purifying rainwater.

[0052] Working principle: Please refer to Figures 1-11 As shown, through the central column 11, when the staff uses the mushroom-shaped antenna 5, the drive motor 8 is first used. The drive shaft of the drive motor 8 rotates, which drives the transmission column 9 and the first gear 10 to rotate. During the rotation, the first gear 10 meshes and drives the second gear 12 and the central column 11 to rotate. At this time, the rotation of the central column 11 drives the extension shell 13 to rotate. Since the initial state of the extension shell 13 is close to the top surface of the mobile communication vehicle body 1, the mushroom-shaped antenna 5 is also close to the top surface of the mobile communication vehicle body 1. When the central column 11 drives the extension shell 13 to rotate, the central column 11 will gradually rotate the extension shell 13 and the mushroom-shaped antenna 5 to a vertical state. Then, the extension shell 13 and the mobile communication vehicle body 1 are in a vertical state. At this time, the top of the extension shell 13 and the position of the mushroom-shaped antenna 5 will be raised, so that the mushroom-shaped antenna 5 can avoid the complex environment and rise to a higher position, so as to avoid the obstruction of the mushroom-shaped antenna 5 signal by the surrounding environment.

[0053] When the drive column 9 and the first gear 10 rotate, the drive rod 21 meshes and drives the second gear 12 and the central column 11 to rotate. The rotation of the central column 11 then drives the first sprocket 17 to rotate. The rotation of the first sprocket 17 drives the second sprocket 19 to rotate via the chain 18. The rotation of the second sprocket 19 drives the rotating column 20 and the drive rod 21 to rotate. When the drive column 9, the first gear 10, the central column 11 and the first sprocket 17 rotate, the first sprocket 17 drives the second sprocket 19 and the rotating column 20 to rotate synchronously via the chain 18. As a result, the extension shell 13 and the drive rod 21 will rotate synchronously to an upright state. During this process, the positions of the drive rod 21 and the extension shell 13 gradually become parallel, and the drive rod 21 pushes against the inner wall of the resistance groove 23 to generate thrust. The drive rod 21 then pushes the extension rod 15 to move the diagonal brace 16 and the mushroom-shaped antenna 5. The extension rod 15 is then pushed out of the storage groove 14 by the drive rod 21, thereby extending the height of the mushroom-shaped antenna 5.

[0054] With the rolling column 26 in place, when the push rod 21 abuts against the inner wall of the resistance groove 23 and pushes the extension rod 15 to move, as the positions of the extension shell 13 and the push rod 21 change, the friction position between the rolling column 26 and the inner wall of the resistance groove 23 also changes. At this time, through the contact between the rolling column 26 and the inner wall of the resistance groove 23, the rolling column 26 can rotate around the fixed column 25, so as to reduce the frictional resistance generated when the push rod 21 changes position in the resistance groove 23.

[0055] With the baffle 30 in place, when the mushroom-shaped antenna 5 is not in use and is attached to the top surface of the mobile communication vehicle body 1, the baffle 30 will block the top surface of the mushroom-shaped antenna 5, which can protect the mushroom-shaped antenna 5 in rainy or snowy weather. When the mushroom-shaped antenna 5 is raised for use, the stepper motor 32 is used. The drive shaft of the stepper motor 32 rotates, which drives the threaded rod 33 to rotate. This allows the slide 34 to move linearly along the inside of the adjustment frame 27. Then, the slide 34 will drive the stabilizing rod 29 and the baffle 30 to move forward, thereby removing the baffle 30 from the top of the mushroom-shaped antenna 5, so that the mushroom-shaped antenna 5 is between the two stabilizing rods 29, allowing the mushroom-shaped antenna 5 to smoothly rotate to a higher position with the extension shell 13.

[0056] Water is injected into the water tank 36 through the nozzle 42, and then pumped out through the water inlet pipe 40 and injected into the diversion pipe 37 through the water outlet pipe 39. The water then enters the spray pipe 41 and is atomized and sprayed out through the nozzle 42, which helps to reduce dust in the environment around the mobile communication vehicle 1 and prevent the mushroom antenna 5 from interfering in sandy and dusty environments.

[0057] With the collection box 44 in place, rainwater will be collected inside the collection box 44 when it rains, and then the rainwater inside the collection box 44 will enter the overflow hole 46 through the collection box 44, thus facilitating the collection of rainwater.
