Description

Technical Field

[0001] This invention pertains to fire-fighting auxiliary equipment, specifically relating to an automatic drainage and zoned winding structure for fire hoses. Background Technology

[0002] Fire hoses are flexible tubes used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber inner lining and an outer surface covered with flax woven material, while advanced fire hoses are made of polymer materials such as polyurethane. Both ends of the fire hose have metal connectors, which can be connected to another hose to extend the distance or to a nozzle.

[0003] After firefighting is completed, fire hoses need to be rolled up. Traditionally, firefighters roll them up manually. Because the hoses are wet and long, and firefighters have just finished firefighting, rolling them up is physically demanding, and it's difficult to squeeze out the remaining water. The rolled-up hoses are also heavier, increasing the burden on subsequent transport, affecting efficiency, and delaying firefighting time. Therefore, when firefighters try to roll up long, wet fire hoses, the hoses often retain too much moisture, resulting in insufficient tightness and weight during the roll.

[0004] Chinese invention patent CN111632325 discloses a fire hose reeling device, including a base plate, a first column and a second column fixed on the base plate, a rotating tube connected to the second column by a bearing, a first baffle fixed to the end of the rotating tube, a central cylinder on the first baffle, a strip-shaped opening on the side wall of the central cylinder, and a driving assembly on the base plate; a first support shaft and a second support shaft on the first column, a first rotating sleeve and a second rotating sleeve respectively fitted on the first and second support shafts, the second support shaft being fixed to the side of the first column, and a pressing assembly on the first column. This fire hose reeling device works by passing the hose between the first and second rotating sleeves and extending it through the strip-shaped opening, embedding the hose head into the central cylinder, and rotating the central cylinder with a motor to reel in the hose. The first and second rotating sleeves squeeze the hose, expelling any residual water from the hose. However, it cannot allow fire hose joints to pass through; it can only wind up fire hoses section by section. It cannot wind up fire hoses with multiple joints, requiring manual operation to wind them up section by section, which cannot truly free up manpower.

[0005] In addition, when the fire hose is being wound up, only a small amount of water remains, and it is flat. The fire hose joint is made of metal and protrudes. When the fire hose and the fire hose joint are wound on the same roll, it is very easy for some fire hose joints to be wrapped around the fire hose. However, when the fire hose is wound up, the fire hose joints slip off and are wound onto another roll. This results in some fire hoses being tightly wound and others slipping and loosening. There is a high-to-low connection slope at the connection between the fire hoses, which causes uneven winding and messy winding of the fire hose. It is easy for the fire hose to get stuck and unable to turn, or to be piled up in a messy state, affecting the winding capacity of the fire hose and affecting the subsequent use of the fire hose.

[0006] Therefore, how to completely solve the problems of fire hoses and fire hose joints not being able to be continuously wound, fire hoses not being able to drain completely, and fire hoses not being able to pass through when folded, and simultaneously achieve continuous winding of fire hoses and fire hose joints, fire hose drainage, and fire hoses that can pass through when folded, and how to divide the fire hose and joint into sections during automatic winding to increase the winding amount and the uniformity and regularity of winding, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to provide a fire hose automatic drainage and zoned winding structure to address the problems in fire hose winding in the prior art.

[0008] Therefore, the above-mentioned objectives of the present invention are achieved through the following technical solutions:

[0009] An automatic drainage and zoned winding structure for fire hoses, characterized in that it includes a drainage transmission structure for winding and an automatic zoned winding structure;

[0010] The drainage transmission structure for winding includes a base and a swing arm pivotally connected to the base on one side. The base and the swing arm are elastically connected by a first spring on the pivotal connection side. The base is provided with a lower pressure roller, and the swing arm is provided with an upper pressure roller. The swing arm is reset by the elastic rebound of the first spring and fixedly clamped to the base by a clamping structure. After the swing arm and the base are clamped, a space is reserved between the upper pressure roller and the lower pressure roller for the fire hose to pass through. The upper pressure roller and the lower pressure roller squeeze the fire hose to drain water. The clamping structure is provided on the side away from the pivotal connection between the swing arm and the base, and can automatically and repeatedly clamp the swing arm and the base.

[0011] A trigger rod is installed on the outside of the upper pressure roller of the swing arm. The trigger rod is equipped with a trigger element. The inner side of the trigger element is fixedly installed on the trigger rod, and the outer side is a gentle arc surface to allow the fire hose connector to contact and rotate from different angles. The fire hose connector pushes the trigger element to rotate, and the rotation of the trigger element drives the trigger rod to rotate to release the clamping structure and push the swing arm to rotate. The clamping structure opens, and the swing arm rotates to open the opening between the base and the upper pressure roller, widening the gap between the upper and lower pressure rollers to allow the fire hose connector to pass through. After the fire hose connector passes through, the first spring rebounds and pulls the swing arm back. The clamping structure automatically clamps the swing arm to the base, so that the upper and lower pressure rollers squeeze and discharge the water in the fire hose.

[0012] The automatic zoned winding structure includes a spool and a hub motor assembly, a stepper motor, and a lead screw. The spool is axially divided into a winding zone and a knotting zone. The hub motor assembly drives the spool to rotate and wind up the fire hose from the drainage transmission structure. A trigger is set at the mating position of the swing arm and the base. When the fire hose joint passes through, the swing arm opens the opening between the base and the trigger, which in turn triggers the stepper motor to run. The stepper motor drives the lead screw to rotate, causing the drainage transmission structure to move to the knotting zone to wind up the fire hose joint. After the fire hose joint passes through, when the swing arm closes with the base, the trigger is triggered again. The stepper motor and the lead screw then drive the drainage transmission structure to move to the winding zone to wind up the fire hose.

[0013] While adopting the above technical solutions, the present invention may also adopt or combine the following technical solutions:

[0014] As a preferred technical solution of the present invention: the reel includes a drum, a drum shaft and a rotating wheel. The drum is rotatably mounted on the base frame via the drum shaft.

The left and right swing arms are respectively fixed to the shafts at both ends of the upper pressure roller. The left and right swing arms are respectively fixed to the upper end of the upper pressure roller and the outer end of the trigger rod, so that when the fire hose interface passes through, the trigger element is triggered first, releasing the clamping structure and allowing the swing arm to rotate relative to the base to expand the distance between the upper and lower pressure rollers.

[0025] The trigger rod is rotatably mounted between the left and right swing arms, and limit hooks are fixedly mounted at both ends of the trigger rod. When the trigger rod rotates, it drives the limit hooks to rotate.

[0026] The base is provided with a hook groove at the matching position. When the limit hook is fastened in the hook groove, it hooks the swing arm on the base. When the trigger rod rotates, it drives the limit hook to rotate away from the hook groove, which drives the swing arm to release the hook from the base. The limit hook is connected to the swing arm through the second spring and is reset to the hook groove by the second spring.

[0027] The hook portion of the limiting hook is a sliding surface.

[0028] As a preferred technical solution of the present invention: the hook groove is provided with a gentle arc surface for the limit hook to move back and forth. The gentle arc surface is located on the upper side of the hook groove. The limit hook slides into or away from the gentle arc surface to hook into or out of the hook groove.

[0031] As a preferred technical solution of the present invention: the lower end of the adjusting rod is provided with an adjusting rod adjusting hole, the adjusting rod adjusting hole is provided with an adjusting inclined surface, and the adjusting inclined surface is used to lock the adjusting screw at different height positions to adjust the height position of the adjusting rod;

[0032] Alternatively, the adjusting rod is placed against the outer wall of the baffle, and dimensions are set on both the baffle and the adjusting rod. The baffle is used as a main scale, and the adjusting rod is used as a vernier to precisely control the height position of the adjusting rod.

[0033] Alternatively, the adjusting component may also be provided with a locking hook, one end of which is rotatably mounted on the baffle, and the other end of which is provided with a groove for a locking limit hook. The locking limit hook rotates to fix the gap between the upper pressure roller and the lower pressure roller.

[0034] As a preferred technical solution of the present invention: the base is provided with a guide slope on the side that is offset from the pivot of the swing arm for the fire hose connector to be supported and slid.

[0040] The drainage transmission structure for fire hose reeling provided by this invention, through the cooperation of a swing arm, base, and clamping structure, achieves continuous and automatic reeling of fire hoses and hose couplings, and can fully drain water from the fire hoses. Utilizing the cooperation of a trigger rod and trigger element, the clamping structure is quickly and accurately released, providing space for the fire hose couplings to open and pass through. The sliding surface of the limiting hook allows it to automatically slide into or out of the hook groove. The smooth arc surface of the hook groove, in cooperation with the sliding surface of the limiting hook, provides elastic space for the passage of folded fire hoses and effectively drains water from single-layer fire hoses. This drainage transmission structure for fire hose reeling eliminates the need for manual reeling of fire hoses piece by piece, enabling automatic and continuous reeling and simultaneous reeling and drainage. The transmission is smooth and can flexibly adapt to the drainage transmission of folded fire hoses or fire hoses containing foreign objects. This invention utilizes an automatic zoned winding structure to automatically drive the drainage transmission structure for winding, enabling zoned transmission of fire hoses and hose couplings. This ensures that the fire hose and hose couplings are respectively conveyed to different positions on the reel for winding, achieving uniform winding of the fire hose and hose couplings onto the reel. The automatic drainage and zoned winding structure provided by this invention is simple, convenient to operate, and has significant application value in the field of fire hose winding. It greatly reduces the workload of firefighters, providing operational flexibility for lightweighting their work. Attached Figure Description

Detailed Implementation

[0053] The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

[0054] Example 1

[0055] like Figures 1-10 As shown, the present invention provides an automatic drainage and zoned winding structure for fire hoses, including a drainage transmission structure for winding and an automatic zoned winding structure.

[0056] The drainage transmission structure for winding includes a base 1 and a swing arm 2 pivotally connected to the base 1 on one side. The base 1 and swing arm 2 are elastically connected on the pivotal connection side by a first spring 5. The base 1 is equipped with a lower pressure roller 4, and the swing arm 2 is equipped with an upper pressure roller 3. The swing arm 2 is elastically returned to its original position by the first spring 5 and is fixedly clamped to the base 1 by a clamping structure. After the swing arm 2 and base 1 are clamped, a space is reserved between the upper pressure roller 3 and the lower pressure roller 4 for the fire hose to pass through. The upper pressure roller 3 and the lower pressure roller 4 squeeze the fire hose to drain water. The clamping structure is located on the side away from the pivotal connection between the swing arm 2 and the base 1, and can automatically and repeatedly clamp the swing arm 2 and the base 1. The swing arm 2 is located outside the upper pressure roller 3. A trigger rod 8 is installed, and a trigger element 801 is provided on the trigger rod 8. The inner side of the trigger element 801 is fixedly installed on the trigger rod 8, and the outer side is a gentle arc surface so that the fire hose connector can contact and push the fire hose connector to rotate from different angles. The fire hose connector pushes the trigger element 801 to rotate, and the rotation of the trigger element 801 drives the trigger rod 8 to rotate to release the clamping structure and push the swing arm 2 to rotate. The clamping structure opens, the swing arm 2 rotates to open the opening with the base 1, and the distance between the upper pressure roller 3 and the lower pressure roller 4 is widened to allow the fire hose connector to pass through. After the fire hose connector passes through, the first spring 5 rebounds and pulls back the swing arm 2. The clamping structure automatically clamps the swing arm 2 with the base 1, so that the upper pressure roller 3 and the lower pressure roller 4 squeeze and discharge the water in the fire hose.

[0057] This invention discloses an automatic drainage and zoned rewinding structure for fire hoses. An upper pressure roller 3 is fixedly mounted on a swing arm 2, and a lower pressure roller 4 is fixedly mounted on a base 1. One end of the swing arm 2 is pivotally mounted on the base 1, and the other end can be repeatedly clamped by a clamping structure. This allows the upper and lower pressure rollers 3 and 4 to pass through the fire hose, squeezing and discharging the water inside. An improved drainage transmission structure for fire hose rewinding utilizes a trigger element 801 to drive a trigger rod 8 to rotate. When a fire hose joint passes through, it pushes the swing arm to rotate, automatically releasing the clamping structure and allowing the fire hose joint to pass automatically. After the fire hose joint passes through, a first spring 5 pulls back the swing arm 2, and the clamping structure automatically clamps the swing arm 2 and the base 1, thus clamping the fire hose between the upper and lower pressure rollers 3 and 4.

[0058] When it is necessary to rewind the fire hose, the clamping structure clamps the opening side of the swing arm 2 and the base 1. The transmission structure for rewinding the fire hose of the present invention squeezes out the remaining water in the fire hose, making it easier to rewind.

[0059] When the fire hose connector needs to pass through, the fire hose connector first touches the trigger 801 and drives the trigger 801 to rotate. The trigger 801 is fixedly installed on the trigger rod 8. The trigger rod 8 is driven to rotate by the trigger 801. The rotation of the trigger rod 8 releases the clamping structure, opens the opening between the swing arm 2 and the base 1, and also expands the distance between the lower pressure roller 4 and the upper pressure roller 3, providing a channel for the fire hose connector to pass through automatically.

[0060] The present invention discloses an automatic drainage and zoned winding structure for fire hoses. Through the cooperation of the clamping structure, the opening and closing of the swing arm 2 and the base 1 are automatically and repeatedly realized, so as to realize the continuous and uninterrupted passage of fire hoses and fire hose joints, and simultaneously realize that the fire hoses can be fully squeezed to drain water and the fire hose joints can pass continuously and smoothly.

[0061] The swing arm 2 and the base 1 can be automatically pulled back and the opening of the swing arm 2 and the base 1 can be reduced by the rebound force of the first spring 5, thus reducing the gap between them. The clamping structure automatically clamps the swing arm and the base 1, so that the upper pressure roller 3 and the lower pressure roller 4 can squeeze and discharge the water in the fire hose.

[0062] The automatic zoned winding structure includes a spool 7, a stepper motor 12, and a lead screw 15. The spool 7 is divided into a winding zone and a knotting zone in the axial direction. The hub motor assembly 16 drives the spool 7 to rotate and wind up the fire hose from the drainage transmission structure. The swing arm 2 and the base 1 are equipped with a trigger 6 at their mating positions. When the fire hose joint passes through, the swing arm 2 opens and the opening of the base 1 triggers the trigger 6. The trigger 6 triggers the stepper motor 12 to run, and the stepper motor 12 drives the lead screw 15 to rotate, causing the drainage transmission structure to move to the knotting zone 708 to wind up the fire hose joint. After the fire hose joint passes through, when the swing arm 2 closes with the base 1, the trigger 6 is triggered, and the stepper motor 12 and the lead screw drive the drainage transmission structure to move to the winding zone 707 to wind up the fire hose.

[0063] In this invention, the automatic winding and drainage of fire hoses are achieved through the cooperation of the drainage transmission structure for winding and the automatic zoned winding structure. Triggered by the trigger 6, the drainage transmission structure for winding is moved to different positions on the smooth rod 17 so that the fire hose can be wound to the winding area 707 and the fire hose joint can be wound to the knot area 708. This achieves continuous, automatic zoned, and effective drainage of the fire hose and fire hose joint, and smooth and orderly winding onto the reel 4. This effectively solves the problems of uneven winding of fire hoses caused by large differences in the shape and height of the fire hose and fire hose joint, and disordered winding and unevenness caused by winding in different axial directions. This avoids reducing the length of the wound fire hose or affecting the removal and use of the fire hose.

[0064] In addition, in the prior art, the length of a fire hose is generally specified as 20 meters. The fire hose connector of the present invention is wound separately into the knot area 708, which also facilitates the quick calculation of the length of the entire wound fire hose and can be quickly used for fire fighting.

[0065] The reel 7 includes a drum 701, a drum shaft 703, and a rotating wheel 702. The drum 701 is rotatably mounted on the base frame via the drum shaft 703. The rotating wheels are fixedly connected to both ends of the drum 701 in the axial direction. When the hub motor assembly drives the rotating wheels to rotate, the fire hose is wound up.

[0066] The outer diameter of the rotating wheel is larger than that of the drum 701 to prevent the fire hose or connector from detaching from the space where the drum 701 is wound.

[0067] The drum 701 is provided with partition columns, and two or more partition columns are arranged radially. Space is reserved between each partition column for the fire hose to pass through. The partition columns are installed on the drum 701 to divide the drum 701 into a winding area and a knotting area.

[0068] The base 1 is provided with guide rail hole 207 and lead screw hole 208. The guide rail is installed through the guide rail hole 207 to slide the base 1. The lead screw 15 is installed through the lead screw hole 208 to drive the winding drainage transmission structure to move. The moving direction is parallel to the axial direction of the roll 7. The lead screw is installed in the lead screw hole 208 to drive the base 1 to slide.

[0069] An automatic control system is provided. The trigger sends a trigger signal to the automatic control system. After receiving the trigger signal, the automatic control system starts the stepper motor to drive the lead screw to move the distributor to the coupling area for winding, and then sends the fire hose connector to the coupling area for winding.

[0070] The reel 7 includes a drum 701, which is mounted on the base frame 5 via a drum shaft 703. The hub motor assembly rotates the drum 701, and the outer wall of the drum 701 rolls the fire hose. In this structure, a drum 701 with a considerable axial length is selected, which can roll the fire hose radially and move axially to roll the fire hose through a conveying mechanism. Through the setting of the partition column 709 and the cooperation of the conveying mechanism, the fire hose and the fire hose interface of the partition are wound separately.

[0071] The outer wall of the drum is provided with a quick-connect interface 704, which is an annular groove. The quick-connect interface 704 is embedded in the drum 701 and is located at the axial end of the drum 701.

[0072] When rolling the fire hose, the fire hose connector is fixed relative to the fire hose connector 704 to achieve quick insertion of the fire hose connector 704, which can start the fire hose winding as quickly as possible.

[0073] The drum 701 is fixedly mounted with rollers 702 at both axial ends. The rollers 702 protrude from the outer wall of the drum 701 to prevent the fire hose from detaching from the drum 701. After the fire hose is wound up, the rollers 702 can roll and move directly on the ground, moving the fire hose synchronously. At the same time, the rollers 702 are provided with several handle holes 705. The handle holes 705 are selected from the gap between the hubs of the rollers 702 to facilitate lifting the drum 701 through the rollers 702.

[0074] The automatic zoned winding structure includes a hub motor 161, which is connected to a rotating wheel 702 to rotate, thereby driving the drum 701 to rotate and roll the fire hose.

[0075] The hub motor 161 is equipped with a mobile power supply drive to facilitate the carrying, transportation and use of the automatic fire hose reel device, while also reducing the weight of the entire automatic fire hose reel device.

[0076] The hub motor 161 drives the external transmission wheel 702. In this structure, both the hub motor 161 and the wheel 702 are made of high friction coefficient round wheels to avoid gear transmission. This is to prevent the hub motor 161 from malfunctioning and the gear from not being able to rotate when the firefighters use it violently. When using high friction coefficient round wheels, even if the hub motor 161 malfunctions, the fire hose can still be wound up by manually rotating the wheel 702 to rotate the drum 701.

[0077] The side of the wheel 702 that contacts the hub motor 161 is made of a flexible material, such as polyurethane, to improve the frictional transmission between the wheel 702 and the hub motor 161.

[0078] The hub motor assembly 16 also includes a transmission mechanism base 162 and a hinge connector 163. The hinge connector 163 is elastically hinged to the transmission mechanism base 162, and the hub motor 161 is mounted on the hinge connector 163. The higher side of the transmission mechanism base 162 is hinged to the hinge connector 163, and the lower side is provided with a tension spring 164. The tension spring 164 elastically presses against the hub motor 161, allowing the hub motor 161 to exert appropriate pressure on the rotating wheel 702, thereby achieving frictional transmission between the hub motor 161 and the rotating wheel 702.

[0079] The hub motor 161 is externally connected to the lower end of the wheel 702 and is elastically hinged to the base 162 of the transmission mechanism via the hinge connector 163 to achieve rotational transmission of the wheel 702. The design of the hinge connector 163 makes it easy for the transmission mechanism to be rotated to the other side and folded up when in use.

[0080] The hub motor 161 of this device is hinged and elastically clamped to ensure the effect of external cutting transmission. Even if the hub motor assembly 16 fails due to operation caused by firefighter violence, it can still be manually wound up.

[0081] In this structure, the stepper motor 12 and the lead screw 15 work together to enable the fire hose to be neatly, orderly and automatically wound up to different positions on the drum 701, which also makes the winding of the fire hose stable and fast.

[0082] In this invention, the base 1 includes two side baffles 101 and a bottom plate 102 that fixes the two side baffles 101. The two side baffles 101 are respectively fixedly installed with shafts at both ends of the lower pressure roller 4. The two side baffles 101 are higher than the lower pressure roller 4 and form a U-shaped opening for the fire hose to pass through and limit its movement. The swing arm 2 includes a left swing arm 201 and a right swing arm 202. The bottom of the left swing arm 201 and the right swing arm 202 are respectively pivotally installed on the outside of the baffle 101. The left swing arm 201 and the right swing arm 202 are respectively fixed with shafts at both ends of the upper pressure roller 3. The left swing arm 201 and the right swing arm 202 are respectively fixedly installed with the two ends of the trigger rod 8 at the upper end of the upper pressure roller 3 and slightly outward, so that when the fire hose interface passes through, the trigger element 801 is triggered first, releasing the clamping structure and allowing the swing arm 2 to rotate relative to the base 1 to expand the distance between the upper pressure roller 3 and the lower pressure roller 4.

[0083] The clamping structure includes a limiting hook 204, a hook receiving groove 104, and a second spring 9; the trigger rod 8 is rotatably installed between the left swing arm 201 and the right swing arm 202, and the limiting hooks 204 are fixedly installed at both ends of the trigger rod 8. When the trigger rod 8 rotates, it drives the limiting hooks 204 to rotate; the base 1 is provided with a hook receiving groove 104 at the matching position. When the limiting hook 204 is hooked into the hook receiving groove 104, it hooks the swing arm 2 onto the base 1; when the trigger rod 8 rotates, it drives the limiting hook 204 to rotate away from the hook receiving groove 104, thereby causing the swing arm 2 to release from the hooking groove 1. The limiting hook 204 is connected to the swing arm 2 through the second spring 9, and is reset to the hook receiving groove 104 by the second spring 9; wherein, the hooking part of the limiting hook 204 is a sliding surface.

[0084] The hooking part of the limiting hook 204 is a sliding surface. In this invention, the hooking part of the limiting hook 204 is a sliding surface, which provides stress and movement direction for the hook receiving groove 104 and the limiting hook 104 to automatically hook or automatically slide.

[0085] The hook groove 104 is provided with a gentle arc surface 1041 for the limit hook 204 to move back and forth. The gentle arc surface 1041 is located on the upper outer side of the hook groove 104. The limit hook 204 slides into or away from the gentle arc surface 1041 to hook the hook groove 204 or to disengage from the hook groove 204.

[0086] When winding up a fire hose, if the thickness suddenly increases due to reasons such as folding of the fire hose, the sliding surface of the smooth arc surface 1041 and the hook of the limit hook can not only cope with the situation of fire hose folding, but also squeeze out water, avoid the jamming of fire hose during winding caused by the fixed distance between the upper and lower pressure rollers, and also avoid the problem of insufficient drainage of fire hose caused by the non-fixed distance between the upper pressure roller 3 and the lower pressure roller 4.

[0087] The hook groove 204 is equipped with a limiting hook guide slope 105, which is located at the sliding front end of the hook groove 204. The limiting hook guide slope 105 provides the limiting hook 204 to gradually open and slide down against the elastic force of the second spring 9 until it is locked in the hook groove 204.

[0088] The hook groove 204 is equipped with an adjustment component 11, which includes a second hook groove 1101 and an adjustment rod 1102. The second hook groove 1101 is fixedly installed on the upper end of the adjustment rod 1102 and is designed to be close to the hook groove 104. The groove of the second hook groove 1101 is similar to the groove of the hook groove 104. The adjustment rod 1102 is height-adjustably installed on the outside of the baffle 101 to adjust the height of the hook limit hook 204 of the second hook groove 1101, adjust the hook angle of the swing arm 2 and the baffle 101, and adjust the distance between the upper pressure roller 3 and the lower pressure roller 4 to adapt to fire hoses of different thicknesses.

[0089] In addition, in this invention, the design of the second hook receiving groove 1101 in the adjusting component 11, the setting of this position, is in conjunction with the fixed installation of the limiting hook 204 at both ends of the trigger rod 8, so that the limiting hook 204 can be a limiting hook of the same thickness, without the need to set the inner hook fastening part, and can be directly hooked on the second hook receiving groove 1101, reducing the processing difficulty of the limiting hook, reducing the material used by the limiting hook 204, and reducing the production cost.

[0090] The lower end of the adjusting rod 1102 is provided with an adjusting rod adjusting hole 1103, and the adjusting rod adjusting hole 1103 is provided with an adjusting inclined surface 1105. The adjusting inclined surface 1105 allows the adjusting screw 1104 to be locked at different height positions to adjust the height position of the adjusting rod 1102. The adjusting rod 1102 is attached to the outer wall of the baffle 101. The baffle 101 and the adjusting rod 1102 are respectively provided with dimensions. The baffle 101 is used as a main scale, and the adjusting rod 1102 is used as a vernier to precisely control the height position of the adjusting rod. The adjusting component 11 is also provided with a locking hook 13. One end of the locking hook 13 is rotatably mounted on the baffle 101, and the other end is provided with a groove for a locking limit hook 204. The locking limit hook 204 rotates to fix the gap between the upper pressure roller 3 and the lower pressure roller 4.

[0091] In this invention, the base 1 is provided with a guide slope 103 on the side that is offset from the pivot of the swing arm 2 for the fire hose connector to be held and slid; the guide slope 103 is provided with a front roller 106 at its lowest point.

[0092] The front roller 106 reduces the force consumed during subsequent fire hose winding, and also improves the overall operational stability and service life of the equipment.

[0093] The first spring 5 is a tension spring, symmetrically arranged on both sides of the baffle 101, connecting the left swing arm 201 to one side baffle 101 and the right swing arm 202 to the other side baffle 101 respectively; the first spring 5 is a torsion spring, and the left swing arm 201 to one side baffle 101 and the right swing arm 202 to the other side baffle 101 are reset by installing a torsion spring at the pivot connection.

[0094] The lower pressure roller 4 has eccentric blocks 14 at both ends of its rotating shaft. The eccentric blocks are square, and the distance from the axis of the lower pressure roller 4 to each side of the eccentric block 14 is different. The eccentric blocks 14 are detachably installed on the base 1, and the installation position of the lower pressure roller 4 on the base 1 can be adjusted by rotating the eccentric blocks 14. By installing the eccentric blocks 14 in different directions, the installation position of the lower pressure roller 4 is adjusted, and the distance between the upper pressure roller 3 and the lower pressure roller 4 can be adjusted. This allows the same automatic drainage and zoned winding structure for fire hoses to be used with fire hoses of different thicknesses, expanding the applicability of the same automatic drainage and zoned winding structure for fire hoses and making it suitable for market promotion and application.

[0095] The above specific embodiments are used to explain and illustrate the present invention, and are only preferred embodiments of the present invention, not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made to the present invention within the spirit and scope of the claims shall fall within the protection scope of the present invention.
