DETAILED DESCRIPTION

[0032] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0033] like Figure 1-Figure 8 As shown, a modular three-wheeled fire station for adaptive sites includes a mobile vehicle 1 and a fire box 2 arranged on the mobile vehicle 1; an upper storage box 21 is arranged on the top of the fire box 2;

[0034] The upper storage box 21 is divided into at least two storage spaces, one of which is rotatably mounted with a first ladder assembly 3, and the other storage space is mounted with a plurality of separated lifting frames 4, which are detachably connected to the first ladder assembly 3 after being connected end to end, and the first ladder assembly 3 and the plurality of lifting frames 4 connected end to end form a life-saving ladder; the fire fighting box 2 is also provided with a first driving assembly, which is used to drive the life-saving ladder to rise;

[0035] The life-saving ladder is provided with an adjustment component. The first ladder component 3 includes a first ladder 31 and a support mechanism 32. The first ladder 31 is connected to the lifting frame 4. One end of the support mechanism 32 is rotatably mounted on the upper locker, and the other end is clamped with the life-saving ladder to support the life-saving ladder at the bottom. The adjustment component is installed with a fire hose 8. The adjustment component is used to adjust the direction of the fire hose 8. The fire hose is a 60-meter fire hose reel.

[0036] When a fire or other emergency occurs in a small place such as a village in the city, the modularly designed three-wheeled fire station can be quickly deployed to the scene. Through simple assembly operations, the various functional modules on the mobile vehicle 1 (such as the fire box 2, storage box, life-saving ladder, etc.) are quickly connected and ready to achieve a rapid response to the scene. When firefighting and rescue are required on the middle and lower floors, the first drive component is first used to start, and the first ladder assembly 3 (including the first ladder 31 and the support mechanism 32) and several sections of separated lifting frames 4 in the upper storage box 21 are taken out from the storage space; then, the lifting frame 4 is connected end to end, and is detachably connected to the first ladder assembly 3 to form a complete life-saving ladder; at this time, the first ladder 31 is rotatably installed on the upper storage cabinet through one end of the support mechanism 32, and the other end is connected to the life-saving ladder to provide bottom support for the life-saving ladder. Afterwards, the driving component is started again to drive the life-saving ladder to rise to the required height as a whole, so as to approach or reach the floor to be rescued; direction adjustment of the fire hose 8: after the life-saving ladder reaches the rescue position, the rescue personnel can use the adjustment component to adjust the direction of the fire hose 8 installed on the life-saving ladder, and by adjusting the spraying angle and position of the fire hose 8, ensure that the water flow can accurately cover the fire source or rescue target, thereby improving the efficiency of fire extinguishing and rescue; in short, through modular design and rapid response mechanism, the present invention can be quickly deployed to small places such as urban villages, and quickly assembled into firefighting and rescue equipment with complete functions, shortening the rescue preparation time and improving the rescue efficiency. In view of the complex building structure and narrow road conditions in urban villages, through the flexible application of adjustment components and drive components, the length and angle of the life-saving ladder can be adjusted according to different floor heights and rescue needs, thereby ensuring the smooth progress of the rescue operation; the support mechanism 32 and the adjustment component effectively enhance the stability and safety of the life-saving ladder; during the rescue process, the safety of the rescue personnel and the rescued can be ensured, and the occurrence of accidents can be reduced.

[0037] In one embodiment, the adjustment assembly includes a rotating mechanism 5 and a second driving mechanism 6; the rotating mechanism 5 is installed at the front end of the first ladder 31 and is used to install the fire hose 8; any elevated frame 4 is rotatably installed with a transmission mechanism 7, the second driving mechanism 6 is installed on the elevated frame 4 away from the first ladder 31, and the rotating mechanism 5 and the second driving mechanism 6 are connected through the transmission mechanism 7; the transmission mechanism 7 is symmetrically arranged at both ends of the elevated frame 4; the rotating mechanism 5 is installed at the front end of the first ladder 31, and the selection of this position facilitates the aiming and spraying of the fire hose 8, and the fire hose 8 is fixed on the rotating mechanism 5 so that the hose The spraying direction can be changed with the action of the rotating mechanism 5. A transmission mechanism 7 is rotatably installed on any elevated frame 4. Several transmission mechanisms 7 are detachably connected to each other to form a stable transmission chain, which can realize changing the spraying direction of the upper fire hose 8 from the bottom, thereby ensuring the continuity and reliability of the transmission. The second driving mechanism 6 is installed on the end elevated frame 4 away from the first ladder 31. When it is necessary to adjust the direction of the fire hose 8, the second driving mechanism 6 is rotated from the bottom of the mobile vehicle 1 to realize the water outlet direction of the top fire hose 8, thereby improving the adaptability of the fire station in complex environments.

[0038] In one embodiment, the transmission mechanism 7 includes a transmission shaft 71; one end of the transmission shaft 71 is an active part and the other end is a passive part. The active part is actively clamped with the passive part of the transmission shaft 71 located at the front end, and the passive part is passively clamped with the active part of the transmission shaft 71 located at the rear end; the active part is symmetrically provided with two clamping strips 72, and an elastic member 73 is provided between the two clamping strips 72 for stretching the symmetrical clamping strips 72; the passive part is provided with a mounting groove 74, and a clamping groove 741 is provided at the end of the mounting groove 74; the mounting groove 74 is used to install the active part, and the clamping strip 72 is clamped in the clamping groove 741; when it is necessary to set up a life-saving ladder, the climbing frame is overlapped in sequence in the front and back order, and the adjacent transmission shafts 71 are clamped front and back. When clamping, the clamping strip 72 is kept in a stretched state under the action of the elastic member 73, so that it can be smoothly clamped into the next-level transmission shaft 71 (that is, the transmission shaft 71 located behind it) The locking cam 77 is in the state of being moved forward, and the locking cam 78 is in the state of being moved forward, and the locking cam 78 is in the state of being moved forward, and the locking cam 78 is in the state of being moved forward, and the locking cam 78 is in the state of being moved forward, and the locking cam 78 is in the state of being moved forward, and the locking cam 78 is in the state of being moved

[0039] In one embodiment, the second driving mechanism 6 includes a first driving tooth and a second driving tooth 62; the first driving tooth is installed on the transmission mechanism 7 on the left, and is used to adjust the horizontal movement of the fire hose 8; the second driving tooth 62 is installed on the transmission mechanism 7 on the right, and is used to adjust the vertical rotation movement of the fire hose 8; the first driving tooth and the second driving tooth 62 have the same structure, and are both circular gears; the first driving tooth is installed on the transmission mechanism 7 on the left, and it serves as a power source in the horizontal direction and is responsible for adjusting the horizontal movement of the fire hose 8. When it is necessary to change the left and right spraying direction of the fire hose 8, the first driving tooth is rotated, and the first driving tooth drives the transmission shaft 71 to rotate, and transmits the rotational force to the rotating mechanism 5 through the transmission shaft 71, so that the rotating mechanism 5 drives the hose to move left and right; similarly, when the fire hose 8 rotates an angle, by rotating the second driving tooth 62, the second driving tooth 62 drives the transmission shaft 71 connected thereto to rotate, and transmits the rotational force to the rotating mechanism 5 through transmission and drives the fire hose 8 to rotate. It is worth noting that the horizontal movement and vertical rotation of the fire hose 8 do not affect each other.

[0040] In one embodiment, the rotating mechanism 5 includes a horizontal moving member 51 and a rotating member 52; the rotating member 52 is installed on the horizontal moving member 51, and the horizontal moving member 51 is connected to the transmission mechanism 7 on the left to adjust the horizontal movement of the fire hose 8; the rotating member 52 is connected to the transmission mechanism 7 on the right to adjust the vertical rotation direction of the fire hose 8; the horizontal moving member 51 includes a moving bevel gear 511, a moving round gear 512 and a screw assembly 513; the moving bevel gear 511 is coaxially connected to the right transmission shaft 71, the moving round gear 512 is meshed with the moving bevel gear 511, and the screw assembly 513 is meshed with the moving round gear 512 to drive the rotating member 52 to move; the rotating member 52 includes an adjusting tooth member, a rotating shaft 521 and an angle block 522; the adjusting tooth member is connected to the transmission shaft 71 connected to the second driving tooth 62, the rotating shaft 521 is installed on the adjusting tooth member, the angle block 522 is coaxially installed with the rotating shaft 521, and the angle block 522 is fixedly connected to the fire hose 8;

[0041] Horizontal movement adjustment: When the transmission mechanism 7 on the left receives power from the first driving tooth, the transmission shaft 71 starts to rotate, and the moving bevel tooth 511 coaxially connected to the transmission shaft 71 rotates in the vertical plane accordingly. The moving round tooth 512 meshing with the moving bevel tooth 511 rotates in the horizontal plane under the drive of the moving bevel tooth 511, and the screw assembly 513 meshes with the moving round tooth 512. Due to the structure of the screw assembly 513, that is, the screw assembly 513 includes a screw rod and a sliding block, the moving bevel tooth 511 drives the screw rod to rotate in the horizontal plane, and when the screw rod rotates, the sliding block makes a linear motion on the screw rod, and the fire hose 8 is installed on the sliding block and makes a linear motion with the sliding block. The left and right movement of the sliding block can be realized by changing the rotation direction of the first driving tooth, and the rotational motion of the first moving round tooth 512 is converted into a linear motion of the screw assembly 513; since the rotating member 52 is installed on the horizontal moving member 51, the rotating member 52 also moves horizontally accordingly.

[0042] Vertical rotation adjustment: When the water outlet angle of the fire hose 8 needs to be changed, the second driving tooth 62 is rotated to drive the transmission shaft 71 connected to the second driving tooth 62 to rotate. At this time, the transmission shaft 71 transmits power to the adjusting tooth part, and the adjusting tooth part transmission shaft 71 rotates and drives the rotating shaft 521 to rotate. When the rotating shaft 521 rotates, it drives the angle block 522 to move up and down. When the rotating block moves up and down, the angle adjustment of the fire hose 8 is realized.

[0043] In one embodiment, the rotating member 52 includes a positioning tooth 93, a fixed scallop 91, a movable scallop 92 and a chain 94; the movable scallop 92 is rotatably mounted on the lead screw assembly 513, the fixed scallop 91 is coaxially connected to the transmission shaft 71 connected to the second drive tooth 62, the positioning tooth 93 is rotatably mounted on the first ladder 31, and the chain 94 is meshed with the fixed scallop 91, the positioning tooth 93 and the movable scallop 92. Since the fire hose 8 can move horizontally and rotate vertically, the rotating member 52 needs to be mounted on the horizontal moving member 51. When the horizontal moving member 51 drives the fire hose 8 to move, the distance is constantly changing. Therefore, in order to enable the rotation of the fire hose 8 to be realized, it is necessary to adjust the transmission force and the problem caused by the movement of the horizontal moving member 51 by adjusting the tooth member; the movable scallop 92 is mounted on the horizontal moving member 5 1. During the movement, the tension of the chain 94 can be adjusted so that the transmission force is transmitted through the chain 94, while the positioning teeth 93 and the fixed round teeth 91 are fixed in position and do not move with the horizontal moving member 51. They serve as fixed points for the transmission of the chain 94 and provide stable transmission support for the movable round teeth 92. In this way, even when the horizontal moving member 51 moves and the distance of the fire hose 8 changes, the power can be stably transmitted; the transmission force received by the fixed round teeth 91 is transmitted to the movable round teeth 92 through the chain 94, so that the movable round teeth 92 rotate, and when the movable round teeth 92 rotate, it drives the rotating shaft 521 to rotate. Since the rotating shaft 521 and the angle block 522 are threadedly connected, and the angle block 522 is fixedly connected to the fire hose 8, when the rotating shaft 521 rotates, it drives the fire hose 8 to move up and down, thereby realizing the adjustment of the water outlet angle. The first driving assembly includes spur teeth 612 arranged on both sides of the life-saving ladder and driving teeth 613 rotatably mounted on the fire-fighting box 2; any spur teeth 612 are meshed with the driving teeth 613; when the life-saving ladder needs to be moved, the driving mechanism (such as a motor or a manual crank) is started to drive the driving teeth 613 to rotate in the fire-fighting box 2. Due to the meshing relationship between the driving teeth 613 and the spur teeth 612 on both sides, the rotation of the driving teeth 613 will drive the meshing spur teeth 612 to move along the tooth surface direction thereof. Since the spur teeth 612 are fixed on both sides of the life-saving ladder, the movement of the spur teeth 612 will further push the life-saving ladder to slide or lift. This meshing transmission has high efficiency because the meshing between the spur teeth 612 and the driving teeth 613 is face-to-face, and the force transmission is direct and effective. In addition, because the meshing transmission has a self-locking function, it can keep the current position when the drive stops.

[0044] In one embodiment, both ends of the elevated frame 4 are hollow main support columns 41, and a plurality of reinforcing bars 42 are arranged in an array between the main support columns 41 at both ends; the transmission shaft 71 is rotatably installed on the hollow main support columns 41 through bearings.

[0045] In one embodiment, the support mechanism 32 includes a support frame 321 and a sliding part 322; one end of the sliding part 322 is rotatably mounted on the fire box 2, and the sliding part 322 is mounted on the other end of the support frame 321. The sliding part 322 is slidably connected to the main support column 41, and the sliding part 322 is located on the side of the straight teeth 612; the support mechanism 32 is mainly composed of the support frame 321 and the sliding part 322, which work together to ensure the stability and safety of the life-saving ladder during horizontal movement or lifting. First, one end of the support frame 321 is fixed to the fire box 2 by a rotatable installation, so that the support frame 321 can rotate to a certain extent around the fixed point, thereby adapting to the support requirements of the life-saving ladder at different angles; secondly, the sliding part 322 is mounted on the other end of the support frame 321 and is slidably connected to the main support column 41. This sliding connection mechanism allows the sliding part 322 to slide freely along a certain direction on the main support column 41, thereby driving the support frame 321 and the life-saving ladder connected thereto to move horizontally or vertically.

[0046] In particular, the sliding portion 322 is located on the side of the spur teeth 612, which means that in the process of the spur teeth 612 meshing with the driving teeth 613 and driving the life ladder to move, the sliding portion 322 can slide along the main support column 41 accordingly with the movement of the life ladder, maintaining a stable connection between the support mechanism 32 and the life ladder. In summary, when the driving teeth 613 in the first drive assembly rotate, the spur teeth 612 and the life ladder are driven to move through the meshing relationship. At the same time, the sliding portion 322 in the support mechanism 32 slides along the main support column 41, providing stable support and guidance for the life ladder, ensuring its stability and safety during movement.

[0047] In one embodiment, the fire fighting box 2 also includes a middle water tank 22, a left storage box 23, a right storage box 24, and a rear control box 25; the middle water tank 22 is used to store water, and in particular, the capacity of the middle water tank 22 is designed to be 0.6 cubic meters, which is sufficient to meet the initial fire fighting needs. The middle water tank 22 is made of high-strength lightweight materials, and has a built-in water level monitoring system and an automatic water replenishing device to ensure that the water source is sufficient and the water quality is safe; the right storage box 24 is symmetrically arranged with the left storage box 23, and different types of fire fighting equipment such as fire extinguishers, fire hoses, and demolition tools are configured according to common fire fighting needs, and a quick access system is set up to facilitate firefighters to quickly equip themselves. The right storage box 24 is specially provided with a storage space for 300 kilograms of NF2000 fire extinguishing agent. This fire extinguishing agent has the advantages of high efficiency, environmental protection, and a wide range of applications, and can quickly and effectively fight different types of fires; the rear control box 25 is integrated with a fire control The system is equipped with a portable power supply and a backup communication system to ensure that it can still work normally under extreme circumstances; the modular configuration allows the various parts of the fire box 2 to be flexibly configured and combined according to actual needs, which can not only operate in various narrow streets, but also facilitate future maintenance and upgrades; on this basis, in order to further improve the water supply efficiency and flexibility of the fire box 2, the present embodiment also specially introduces a double-pole water supply system with models DN25 and DN30. This water supply system realizes the rapid transmission and distribution of water sources through the setting of double poles. Specifically, the DN25 and DN30 water supply pipes are respectively connected to different water outlets of the middle water tank 22, ensuring that the fire hoses or other fire-fighting equipment can obtain sufficient water supply at the same time; at the same time, the introduction of the double-pole water supply system also improves the water supply stability and reliability of the fire box in complex environments, providing a more solid guarantee for fire-fighting operations.

[0048] In one embodiment, an autofocus module is also included, and the autofocus module is used to automatically focus on the fire point; the autofocus module includes a main control unit and a monitoring unit electrically connected to the main control unit, a first drive motor and two second drive motors; the monitoring unit is installed on the first ladder and can capture the image of the fire scene in real time, especially the location of the fire point; the monitoring unit identifies and determines the specific location of the fire point through image recognition technology, and uploads the information to the main control unit; after receiving the fire point location information uploaded by the monitoring unit, the main control unit performs data processing and analysis; according to the analysis results, the main control unit sends corresponding control instructions to the first drive motor and the second drive motor, and the first drive motor is coaxially connected to the drive gear for adjusting the fire hose or related fire extinguishing equipment height; according to the instruction of the main control unit, the first drive motor drives the drive gear to rotate, so that the lifting frame is raised or lowered, so that the fire hose or fire extinguishing equipment reaches the best spraying height for the fire point; the two second drive motors are coaxially connected to the transmission mechanism on the right and left respectively, and are used to adjust the horizontal position and water outlet angle of the fire hose; according to the instruction of the main control unit, the two second drive motors work together to adjust the water outlet angle of the fire hose through the transmission mechanism to ensure that the water flow can be accurately sprayed to the fire point; through the automatic focus module, the fire station can quickly identify and locate the fire point, and automatically adjust the height and water outlet angle of the fire hose. By integrating the automatic focus module and the intelligent control system, the fire station realizes intelligent monitoring and response to the fire scene.
