Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, and in particular to a fire hose box with a built-in rapid retraction and unwinding mechanism. Background Technology

[0002] A fire hose box is a specialized fire-fighting facility used to store fire hoses, nozzles, connectors, and related fire-fighting accessories. It is widely used in buildings, ships, factories, and other locations. Its core function is to properly store fire-fighting equipment, protect it from external environmental corrosion, and ensure that firefighters can quickly retrieve hoses and connect them to a water source for emergency firefighting in the event of a fire. Currently, most fire hose boxes on the market use a purely manual hose reeling system. After the fire is extinguished, firefighters must manually unwind and re-wrap the unfolded hoses before placing them one by one into the box for storage. Manual hose reeling has several drawbacks: First, it is labor-intensive. The unfolded hose is heavy, requiring significant manpower for manual reeling, especially after continuous firefighting operations when firefighters are exhausted, drastically reducing reeling efficiency. Second, it results in poor reeling regularity; manual operation easily leads to uneven winding and wrinkles, which over time damage the hose's sealing performance and shorten its lifespan. Third, it delays emergency preparedness; manual reeling is time-consuming, and if a fire reignites or a secondary fire occurs, the hose cannot be quickly retrieved and put back into use, posing a safety hazard. Existing fire hose boxes lack automatic reeling mechanisms and have a simplistic design, failing to address the inherent shortcomings of manual reeling. Therefore, providing a fire hose box that enables automatic hose reeling, reduces labor intensity, and improves emergency response efficiency is a pressing technical problem in this field. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the existing fire hose boxes adopt a manual winding method, which is labor-intensive, has poor winding regularity, delays in emergency preparation, and lacks automatic lifting and adjustment function.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a fire hose box with a built-in quick-release mechanism, including a main box body, a longitudinal guide rail, a built-in transmission seat, a pull-out quick-release mechanism, and a top-mounted control motor; the longitudinal guide rail is fixedly installed on the inner wall of the main box body, the built-in transmission seat is slidably assembled inside the longitudinal guide rail, the pull-out quick-release mechanism is installed on the outer surface of the built-in transmission seat, the top-mounted control motor is fixedly installed at the upper end of the main box body, and the built-in synchronous transmission shaft for driving the pull-out quick-release mechanism and the top-mounted control motor is movably assembled inside the built-in transmission seat.

[0005] Furthermore, the pull-out quick-release mechanism includes an external mounting protrusion mounted on the outer side of the built-in transmission seat, an external pull-out extension tube movably fitted on the outside of the external mounting protrusion, and an elastic limiting protrusion elastically fitted on the outer side of the external pull-out extension tube.

[0006] Furthermore, a flip handle is hinged to the outer end of the external pull-out extension tube, and an end pressing block for controlling the elastic limiting protrusion is elastically fitted on the outer surface of the external mounting protrusion. The end pressing block is electromagnetically controlled to retract the elastic limiting protrusion inward and separate from the external pull-out extension tube.

[0007] Furthermore, the built-in synchronous drive shaft includes a longitudinal main drive shaft located inside the built-in drive seat, a transverse main drive shaft axially fixed to the center of the external mounting cam, and a synchronous transmission gear set installed between the longitudinal main drive shaft and the transverse main drive shaft.

[0008] Furthermore, the built-in transmission seat has lateral adjustment internal thread sliders extending into the longitudinal guide rail on both sides, and a built-in lifting screw for adjusting the lateral adjustment internal thread slider is movably mounted inside the longitudinal guide rail.

[0009] Furthermore, a magnetically controlled telescopic switching module is installed at the top of the longitudinal main drive shaft and the built-in lifting screw.

[0010] Furthermore, the magnetically controlled telescopic switching module includes a first top-mounted control seat axially fixed to the top of the longitudinal main drive shaft, a second top-mounted control seat axially fixed to the top of the built-in lifting screw, a magnetically controlled inner tooth block slidably fitted on the outside of the first top-mounted control seat, and a magnetically controlled outer tooth block slidably fitted on the outside of the second top-mounted control seat. The bottom control shaft of the top-mounted control motor is coaxially fixed with a bottom end tooth that cooperates with the magnetically controlled inner tooth block and an external gear that cooperates with the magnetically controlled outer tooth block.

[0011] Furthermore, the magnetically controlled internal gear block includes a first guide shaft fixed on the outer plane of the first top control seat, a first electromagnet fixed at the end of the first guide shaft, and a first iron spring sleeved on the outer side of the first guide shaft. The magnetically controlled external gear block includes a second guide shaft fixed on the outer plane of the second top control seat, a second electromagnet fixed at the end of the second guide shaft, and a second iron spring sleeved on the outer side of the second guide shaft.

[0012] Furthermore, the inner ends of the external pull-out extension tube are provided with lateral limiting grooves that cooperate with the elastic limiting protrusions.

[0013] Furthermore, a top-mounted optical recognition module is fixedly installed on the top surface of the main housing to optically recognize and control the winding status and height of the fire hose.

[0014] The beneficial effects of this invention are:

[0015] (1) Improved fire emergency efficiency: The magnetic telescopic switching module is driven by the top-mounted control motor. The magnetic inner tooth block and the magnetic outer tooth block mesh with the bottom tooth head and the external gear under electromagnetic action, respectively, realizing one-key electromagnetic switching between winding drive and lifting drive. No manual intervention is required, which greatly shortens the winding time.

[0016] (2) Reduced labor intensity: The pull-out quick-release mechanism can be extended to the outside of the box, and the flip handle facilitates the unfolding and winding of the fire hose; the built-in drive mechanism automatically completes the winding and height adjustment of the fire hose, so firefighters do not need to manually arrange and wrap it.

[0017] (3) Good winding regularity: The built-in transmission seat moves up and down along the longitudinal guide rail to match the winding height of the water hose, so that the water hose is evenly distributed during the winding process, avoiding uneven winding and wrinkles; the top optical recognition module monitors the winding status of the water hose in real time to ensure neat winding.

[0018] (4) High safety and reliability: The end extrusion block achieves reliable locking and releasing of the external pull-out extension tube through the electromagnetically controlled elastic limiting protrusion, making operation convenient and quick. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0028] like Figures 1-6 As shown, a fire hose box with a built-in rapid winding and unwinding mechanism includes a main box body 100, longitudinal guide rails 110, a built-in transmission seat 120, a pull-out rapid winding and unwinding mechanism 200, a top-mounted control motor 300, and a built-in synchronous transmission shaft 400. The main box body 100 is a rectangular box structure and is installed at the fire equipment installation location of a building or ship. Two longitudinal guide rails 110 are fixedly installed on the rear wall of the main box body 100, and the longitudinal guide rails 110 are arranged parallel to each other in the vertical direction. Laterally adjustable internal threaded sliders 130 are provided on both sides of the built-in transmission seat 120, and the laterally adjustable internal threaded sliders 130 are slidably assembled in the longitudinal guide rails 110. The longitudinal guide rail 110 is internally fitted with a built-in lifting screw 140, which is threadedly engaged with the lateral adjustment internal thread slider 130. The rotation of the built-in lifting screw 140 drives the built-in transmission seat 120 to move up and down along the longitudinal guide rail 110, thereby adjusting the height position of the pull-out quick-release mechanism 200.

[0029] A pull-out quick-release mechanism 200 is installed on the outer surface of the built-in transmission base 120. The pull-out quick-release mechanism 200 includes an external mounting protrusion 210, an external pull-out extension tube 220, and elastic limiting protrusions 230. The external mounting protrusion 210 is a cylindrical structure and is fixed at the center of the outer side of the built-in transmission base 120. The external pull-out extension tube 220 is movably fitted on the outside of the external mounting protrusion 210 and can be pulled outward axially. Elastic limiting protrusions 230 are elastically fitted at both ends of the outer side of the external pull-out extension tube 220, and lateral limiting grooves 260 are opened at both ends of the inner side of the external pull-out extension tube 220 to cooperate with the elastic limiting protrusions 230. In its natural state, the elastic limiting protrusions 230 pop outward and engage with the lateral limiting grooves 260 to limit the axial displacement of the external pull-out extension tube 220. The outer end of the external pull-out extension tube 220 is hinged with a flip handle 240, which can be flipped to facilitate the pulling out of the external pull-out extension tube 220. An end pressing block 250 is elastically fitted on the outer surface of the external mounting protrusion 210. When it is necessary to release the external pull-out extension tube 220, the end pressing block 250 is driven by electromagnetic force to press the elastic limiting protrusion 230 inward, so that the elastic limiting protrusion 230 separates from the lateral limiting groove 260, and the external pull-out extension tube 220 can be pulled out freely.

[0030] An internal synchronous drive shaft 400 is installed inside the internal drive base 120 and includes a longitudinal main drive shaft 410, a transverse main drive shaft 420, and a synchronous drive gear set 430. The longitudinal main drive shaft 410 is vertically positioned inside the internal drive base 120, while the transverse main drive shaft 420 is axially fixed to the center of the external mounting protrusion 210 in the horizontal direction. The longitudinal main drive shaft 410 and the transverse main drive shaft 420 are connected by the synchronous drive gear set 430. The rotation of the longitudinal main drive shaft 410 is transmitted to the transverse main drive shaft 420 through the synchronous drive gear set 430, thereby driving the rotation of the external pull-out extension cylinder 220, which is fitted outside the transverse main drive shaft 420. The hose is manually fitted onto the outside of the external pull-out extension cylinder 220 to achieve the winding or unfolding operation of the hose.

[0031] A top-mounted control motor 300 is fixedly installed on the upper end of the main housing 100. A magnetically controlled telescopic switching module 500 is installed on the top of the longitudinal main drive shaft 410 and the built-in lifting screw 140. The magnetically controlled telescopic switching module 500 includes a first top-mounted adjustment seat 510, a second top-mounted adjustment seat 520, a magnetically controlled internal gear block 530, and a magnetically controlled external gear block 540. The first top-mounted adjustment seat 510 is axially fixed to the top of the longitudinal main drive shaft 410, and the second top-mounted adjustment seat 520 is axially fixed to the top of the built-in lifting screw 140. The magnetically controlled internal gear block 530 is slidably fitted on the outside of the first top-mounted adjustment seat 510. The magnetically controlled internal gear block 530 includes a first guide shaft 531 fixed on the outer plane of the first top-mounted adjustment seat 510, a first electromagnet 532 fixed to the end of the first guide shaft 531, and a first iron spring 533 sleeved on the outside of the first guide shaft 531. The magnetically controlled external gear block 540 is slidably fitted onto the outside of the second top-mounted control seat 520. The magnetically controlled external gear block 540 includes a second guide shaft 541 fixed on the outer plane of the second top-mounted control seat 520, a second electromagnet 542 fixed to the end of the second guide shaft 541, and a second iron spring 543 sleeved on the outside of the second guide shaft 541. A bottom end gear 550 and an external gear 560 are coaxially fixed on the bottom control shaft of the top-mounted control motor 300.

[0032] The working principle of the magnetically controlled telescopic switching module 500 is as follows: When the first electromagnet 532 is energized, the magnetically controlled inner tooth block 530 slides upward along the first guide shaft 531 under the attraction of the first electromagnet 532, engaging with the bottom tooth head 550. The top-mounted control motor 300 drives the magnetically controlled inner tooth block 530 to rotate through the bottom tooth head 550, thereby driving the first top-mounted adjustment seat 510 and the longitudinal main drive shaft 410 to rotate, realizing the winding drive. When the first electromagnet 532 is de-energized, the first iron spring 533 resets the magnetically controlled inner tooth block 530 and pushes it back, separating it from the bottom tooth head 550. When the second electromagnet 542 is energized, the magnetically controlled external gear block 540 slides upward along the second guide shaft 541 under the attraction of the second electromagnet 542, meshing with the external gear 560. The top-mounted control motor 300 drives the magnetically controlled external gear block 540 to rotate through the external gear 560, thereby driving the second top-mounted adjustment seat 520 and the built-in lifting screw 140 to rotate, realizing the lifting drive of the built-in transmission seat 120. When the second electromagnet 542 is de-energized, the second iron spring 543 pushes the magnetically controlled external gear block 540 back to its original position, separating it from the external gear 560. By controlling the energization and de-energization of the first electromagnet 532 and the second electromagnet 542, electromagnetic one-button switching between winding drive and lifting drive is realized.

[0033] A top-mounted optical recognition module 600 is fixedly installed on the top surface inside the main housing 100. The top-mounted optical recognition module 600 uses infrared or visual sensors to perform real-time optical recognition of the winding status and height of the fire hose. The top-mounted optical recognition module 600 is electrically connected to the top-mounted control motor 300. When it detects uneven winding of the fire hose or the need for height adjustment, it sends a control signal to the top-mounted control motor 300, automatically switching to the lifting drive mode or the winding drive mode for adjustment. After winding is completed, the top-mounted optical recognition module 600 controls the magnetic telescopic switching module 500, so that the magnetic control outer tooth block 540 meshes with the outer gear 560, and the bottom tooth head 550 separates from the magnetic control inner tooth block 530, controlling the lifting of the wound belt to avoid interference with the water pipes and other structures at the bottom, facilitating storage; when releasing, it first unfolds outward and then descends.

[0034] This invention achieves electromagnetic switching between winding and lifting by using a magnetically controlled telescopic switching module 500. Combined with the automatic detection and control of the top-mounted optical recognition module 600, it realizes integrated operation of automatic winding and height adjustment of the fire hose, completely replacing the traditional manual winding method, greatly reducing the labor intensity of firefighters and improving the efficiency of fire emergency response.

The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
