Description

Technical Field

[0001] This invention belongs to the field of mobile fire-fighting equipment technology, specifically a mobile fire-fighting equipment device. Background Technology

[0002] Mobile fire-fighting equipment is a new type of fire-fighting equipment with flexible relocation capabilities and on-site fire-fighting functions. It typically integrates a water storage container, a spray mechanism, a mobile chassis, and corresponding drive and control components. This type of equipment aims to solve the problems of limited coverage and slow response speed of traditional fixed fire-fighting facilities. It can quickly reach the fire scene and carry out initial fire suppression, and is particularly suitable for large spaces such as warehouses, workshops, and exhibition halls. Its core design concept is to balance the ease of movement and operational stability of the equipment, achieving a unified approach of rapid deployment and efficient fire suppression through structural innovation, thereby improving the overall effectiveness of fire emergency response.

[0003] However, existing mobile fire-fighting equipment still suffers from numerous technical shortcomings in practical applications. Firstly, most devices use fixed wheel assemblies, which cannot be effectively retracted during firefighting operations. This makes the device prone to slipping, deflection, or even overturning due to water flow reaction forces or uneven ground, seriously threatening operational safety and the continuity of firefighting efforts. Secondly, traditional devices have a single method for adjusting the angle of the water spray components, making it difficult to adjust the spray direction in real time according to changes in the fire's intensity, reducing firefighting accuracy and efficiency. Furthermore, the connection between the water tank and the chassis is often directly fixed with bolts, making disassembly and assembly cumbersome and hindering rapid replacement and water replenishment after use, thus affecting the device's continuous operational capability. Therefore, there is an urgent need to systematically optimize the structure of existing mobile fire-fighting equipment to solve the aforementioned key problems restricting its widespread use. Summary of the Invention

[0004] The purpose of this invention is to provide a portable fire-fighting equipment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mobile fire-fighting equipment device, comprising a base, a supporting shell, casters, a lifting mechanism, and a water storage tank;

[0006] The supporting shell is fixed to the bottom of the base;

[0007] The lifting mechanism is installed inside the base and is used to retract the casters into the support housing.

[0008] The lifting mechanism includes a drive motor, a bidirectional threaded rod, a threaded block, an active connecting rod, a crossbar, and a slide bar;

[0009] The drive motor is fixed inside the base, and the bidirectional threaded rod is fixed to the output end of the drive motor. At the same time, the end of the bidirectional threaded rod away from the drive motor is rotatably connected to the base. There are two sets of threaded blocks, and the two sets of threaded blocks are respectively threaded to both ends of the bidirectional threaded rod. One end of the active connecting rod is hinged to the threaded block, and the crossbar is hinged to the end of the active connecting rod away from the threaded block. At the same time, the sliding rod is fixed to the end of the crossbar away from the active connecting rod.

[0010] As a further preferred embodiment of this technical solution: a telescopic rod is fixedly connected inside the support housing, and a connecting block is fixedly connected to the end of the telescopic rod away from the support housing. At the same time, the connecting block is fixedly connected to the slide rod, and the end of the connecting block away from the telescopic rod is fixedly connected to the universal wheel. Meanwhile, a return spring is sleeved on the telescopic rod, and the two ends of the return spring are respectively fixed to the support housing and the connecting block, which is used to assist the universal wheel in retraction.

[0011] As a further preferred embodiment of this technical solution: a square column is fixedly connected to the base, and an angle adjustment mechanism is installed on the base for adjusting the water spray direction. The angle adjustment mechanism includes a turntable, an electric push rod, a water spray gun, a universal joint, and a water supply pipe.

[0012] The turntable is rotatably connected to the base, while the electric push rod is hinged to the turntable, and the water gun is hinged to the end of the electric push rod away from the turntable. At the same time, the universal joint is rotatably connected to the square column, and the end of the universal joint away from the square column is fixed to the water gun. One end of the water supply pipe is fixed to the tail end of the water gun, and the end of the water supply pipe away from the water gun can be detachably installed on the water storage tank.

[0013] As a further preferred embodiment of this technical solution: pads are fixedly connected to the front and rear ends of the base, the water tank is attached to the pads, and the pads are provided with slots. An insert plate is fixedly connected to the bottom of the water tank. The insert plate is inserted into the slot. Both the slot and the insert plate are provided with threaded holes. Bolts are threaded through the threaded holes to fix the position of the water tank on the pads.

[0014] As a further preferred embodiment of this technical solution: the water gun is fixedly equipped with a directional handle for controlling the direction of water spraying;

[0015] As a further preferred embodiment of this technical solution: the bottom of the base is provided with a sliding groove, and the active connecting rod passes through the sliding groove;

[0016] As a further preferred embodiment of this technical solution: the supporting shell is provided with a guide groove, and the slide rod is slidably connected through the guide groove to limit and guide the lifting and lowering of the caster wheel;

[0017] As a further preferred embodiment of this technical solution: a handle is fixedly connected to the base for pushing the fire-fighting device, and a water injection pipe is fixedly connected through the top of the water storage tank.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, a drive motor drives a bidirectional threaded rod to rotate, causing two sets of threaded blocks to move towards or away from each other. Then, through the linkage of the active connecting rod, cross rod, and sliding rod, the caster wheel is driven to precisely lift and lower relative to the supporting shell. When the device needs to be moved a long distance, the caster wheel extends out from the bottom of the supporting shell to ensure flexible and labor-saving movement. When the device reaches the fire scene and firefighting operations begin, the caster wheel can be smoothly retracted into the supporting shell, so that the entire device is stably supported on the ground by the base. This effectively prevents the equipment from sliding or overturning due to the reaction force of water flow or uneven ground, ensuring the continuity and safety of firefighting operations.

[0020] Meanwhile, the coordinated design of the telescopic rod and the return spring provides elastic assistance during the retraction of the caster wheels, reducing the driving load on the motor, improving the smoothness of the lifting action and the service life of the components.

[0021] 2. In this invention, the angle adjustment mechanism, through the cooperation of a turntable, an electric push rod, and a universal joint, can flexibly adjust the pitch angle and horizontal orientation of the water gun, enabling firefighters to adjust the spray direction in real time according to changes in the fire situation. Combined with the directional handle, it achieves precise control and significantly improves fire extinguishing efficiency.

[0022] 3. In this invention, the water tank is quickly positioned by inserting a plate and using slots on the pad, and is securely locked by bolts through threaded holes. This ensures a stable connection of the water tank during operation, facilitates disassembly, replacement, or water replenishment maintenance after use, and also makes it easy to remove the water tank and move the fire-fighting equipment.

[0028] 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.

[0029] Example

[0030] Please see Figures 1-4 As shown, the present invention provides a technical solution: a mobile fire-fighting equipment device, including a base 1, a supporting shell 2, casters 3, a lifting mechanism 4, and a water storage tank 11;

[0031] The outer casing 2 is fixed to the bottom of the base 1;

[0032] The lifting mechanism 4 is installed inside the base 1 and is used to retract the casters 3 into the support housing 2;

[0033] The lifting mechanism 4 includes a drive motor 41, a bidirectional threaded rod 42, a threaded block 43, an active connecting rod 44, a crossbar 45, and a slide bar 46;

[0034] The drive motor 41 is fixedly connected to the base 1, and the bidirectional threaded rod 42 is fixedly connected to the output end of the drive motor 41. At the same time, the end of the bidirectional threaded rod 42 away from the drive motor 41 is rotatably connected to the base 1. There are two sets of threaded blocks 43, and the two sets of threaded blocks 43 are respectively threaded and connected to the two ends of the bidirectional threaded rod 42. One end of the active connecting rod 44 is hinged to the threaded block 43, and the cross rod 45 is hinged to the end of the active connecting rod 44 away from the threaded block 43. At the same time, the slide rod 46 is fixedly connected to the end of the cross rod 45 away from the active connecting rod 44.

[0035] Further: The base 1 is welded from high-strength steel plate, and a rectangular frame-shaped support shell 2 is fixedly installed at its bottom. The lifting mechanism 4 is arranged in the internal cavity of the base 1. The drive motor 41 is a forward and reverse stepper motor. The output shaft of the drive motor 41 is connected to the bidirectional threaded rod 42 through a coupling. The two ends of the bidirectional threaded rod 42 are respectively provided with threaded sections with opposite directions of rotation, and the end away from the drive motor 41 is supported on the side wall of the base 1 by a rolling bearing. At the same time, two sets of threaded blocks 43 are respectively adapted to and screwed into the two threaded sections.

[0036] In this embodiment, specifically: a telescopic rod 5 is fixedly connected inside the support shell 2, and a connecting block 7 is fixedly connected to the end of the telescopic rod 5 away from the support shell 2. At the same time, the connecting block 7 is fixedly connected to the slide rod 46, and the end of the connecting block 7 away from the telescopic rod 5 is fixedly connected to the universal wheel 3. Meanwhile, a return spring 6 is sleeved on the telescopic rod 5, and the two ends of the return spring 6 are fixedly connected to the support shell 2 and the connecting block 7 respectively, which is used to assist the universal wheel 3 to retract.

[0037] Furthermore: When the caster wheel 3 extends, the telescopic rod 5 is stretched, the return spring 6 is compressed and stores elastic potential energy; when the drive motor 41 reverses and causes the active connecting rod 44 to fold, the return spring 6 releases its elastic force to assist in pulling the connecting block 7 upward to reset, thereby reducing the load on the drive motor 41, while ensuring the speed and smoothness of the caster wheel 3 retraction action.

[0038] In this embodiment, specifically: a square column 8 is fixedly connected to the base 1, and an angle adjustment mechanism 9 is installed on the base 1 to adjust the water spray direction. The angle adjustment mechanism 9 includes a turntable 91, an electric push rod 92, a water spray gun 93, a universal joint 94, and a water supply pipe 95.

[0039] The turntable 91 is rotatably connected to the base 1, while the electric push rod 92 is hinged to the turntable 91, and the water gun 93 is hinged to the end of the electric push rod 92 away from the turntable 91. At the same time, the universal joint 94 is rotatably connected to the square column 8, and the end of the universal joint 94 away from the square column 8 is fixed to the water gun 93. One end of the water supply pipe 95 is fixed to the tail end of the water gun 93, and the end of the water supply pipe 95 away from the water gun 93 can be detachably installed on the water storage tank 11.

[0040] Further: During operation, the turntable 91 rotates to adjust the horizontal azimuth angle, and the electric push rod 92 extends and retracts to adjust the pitch angle. The two work together to achieve multi-angle spraying of the fire source.

[0041] In this embodiment, specifically: pads 10 are fixedly connected to the front and rear ends of the base 1, the water tank 11 is attached to the pads 10, and the pads 10 are provided with slots 12. The bottom of the water tank 11 is fixedly connected with a plate 13, which is inserted into the slot 12. Both the slot 12 and the plate 13 are provided with threaded holes 14, and bolts 15 are threadedly connected through the threaded holes 14 to fix the position of the water tank 11 on the pads 10.

[0042] Further: During installation, the water tank 11 is placed from top to bottom, so that the insert plate 13 is vertically inserted into the slot 12. The wing bolts 15 are then tightened through the threaded holes 14 on the side wall of the insert plate 13 and the slot 12 to secure the water tank 11 to the pad 10. This prevents the water tank 11 from shifting due to vibration or external force during firefighting operations. When disassembling, simply loosen the bolts 15 and lift the water tank 11 upwards. The operation is simple and quick.

[0043] In this embodiment, specifically: a directional handle 16 is fixedly attached to the water gun 93 for controlling the direction of water spraying.

[0044] Further: A directional handle 16 extending laterally is welded to the outer wall of the middle part of the water gun 93. The surface of the directional handle 16 is provided with anti-slip knurling. When firefighters are performing fire extinguishing operations, they can hold the directional handle 16 with one hand or both hands and adjust the direction of the water gun 93 in real time in conjunction with the action of the angle adjustment mechanism 9.

[0045] In this embodiment, specifically: the bottom of the base 1 is provided with a sliding groove 17, and the active connecting rod 44 passes through the sliding groove 17;

[0046] The supporting housing 2 is provided with a guide groove 18, and the slide rod 46 is slidably connected in the guide groove 18 to limit and guide the lifting of the caster wheel 3.

[0047] Furthermore, the slide rod 46 is slidably inserted into the guide groove 18. The width of the guide groove 18 is clearance-fitted with the outer diameter of the slide rod 46 to ensure that the slide rod 46 can only move up and down in the vertical direction and cannot be horizontally offset or twisted. This accurately guides the lifting path of the caster wheel 3, ensuring that the four caster wheels 3 extend or retract synchronously and stably, and avoiding jamming or deflection.

[0048] In this embodiment, specifically: a handle is fixedly connected to the base 1 for pushing the fire-fighting device, and a water injection pipe is fixedly connected through the top of the water storage tank 11.

[0049] Further: A U-shaped push-pull handle is welded to the rear end of the base 1, and a rubber grip sleeve is fitted on the outer end of the handle to facilitate firefighters to push the entire device. A vertical water injection pipe is provided at the top center of the water storage tank 11. The upper end of the water injection pipe is open and equipped with a sealing cap for adding fire water or foam mixture into the water storage tank 11.

[0050] Working principle or structural principle: When the device needs to be moved, the drive motor 41 in the lifting mechanism 4 drives the bidirectional threaded rod 42 to rotate in the forward direction, causing the two sets of threaded blocks 43 to move towards each other along the bidirectional threaded rod 42. This, in turn, pushes the active connecting rod 44 and the crossbar 45 to swing downward, and drives the slide rod 46 to slide downward along the guide groove 18, causing the caster wheel 3 to extend from the bottom of the support housing 2. At the same time, the telescopic rod 5 is stretched and the return spring 6 is compressed. At this time, the device can be moved by pushing it with the handle. When the device needs to be fixed at the fire extinguishing position, the drive motor 41 rotates in the reverse direction, causing the two sets of threaded blocks 43 to move in opposite directions, driving the active connecting rod 44 and the crossbar 45 to retract upward, cooperating with the return spring. The elastic recoil force of spring 6 assists the slide bar 46 to slide upward, thereby completely retracting the caster wheel 3 into the support housing 2, making the base 1 firmly attached to the ground, ensuring the stability of the device during fire extinguishing. During fire extinguishing, the water tank 11 is inserted into the slot 12 of the pad block 10 through the insert plate 13 and locked by the bolt 15 through the threaded hole 14. Water is delivered to the water gun 93 through the water supply pipe 95. At the same time, the turntable 91 in the angle adjustment mechanism 9 can rotate horizontally to adjust the water spray direction. The electric push rod 92 extends and retracts, driving the water gun 93 to tilt and swing around the universal axis 94. Firefighters can further fine-tune the spray angle by holding the direction handle 16, thereby achieving multi-directional and precise fire extinguishing operations.

[0051] 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.
