DETAILED DESCRIPTION

[0041] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below in conjunction with the drawings in the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0042] The water hose winding device of the present application will be described below in conjunction with Figures 1 to 6

[0043] Referring to Figure 1 , the first aspect embodiment of the present application provides a water hose winding device, which comprises a support 100, a first rotating cylinder 110, a plurality of first support beams 120 and a first elastic member 130. The first rotating cylinder 110 is installed on the support 100 through a rotating shaft 101. The plurality of first support beams 120 are arranged outside the first rotating cylinder 110 in parallel to the rotating shaft 101, and the plurality of first support beams 120 are arranged at equal intervals. A plurality of grooves with tooth-like distribution are formed on the plurality of first support beams 120, and the shape of the grooves matches the shape of the water hose 102 in a water-filled state. The first elastic member 130 is connected between the first rotating cylinder 110 and the first support beam 120, and the first elastic member 130 is adapted to deform so that the first support beam 120 approaches or moves away from the first rotating cylinder 110.

[0044] ​The water hose winding device provided by the embodiment of the present application is provided with a plurality of first support beams 120, and the first support beams 120 are provided with tooth-shaped grooves, so that the water hose 102 can be accommodated in the tooth-shaped grooves when being wound; the grooves are shaped to match the shape of the water hose 102 in the water-filled state, thereby creating conditions for winding and releasing the water hose 102 in the water-filled state; the first support beams 120 can float relative to the first rotating cylinder 110 by providing the first elastic member 130, thereby providing space for the water hose 102 to expand radially inward along the first rotating cylinder 110 when being filled with water, and thereby reducing the winding and releasing time and meeting the emergency fire-fighting requirements without the need to empty the water hose 102 when being wound and without the need to wait for the water hose 102 to be released when being used.

[0045] Specifically, please refer to Figure 1 The support 100 is composed of a bottom plate and two vertical plates, and is used for supporting the water hose winding device. The two vertical plates are perpendicular to the bottom plate, that is, the two vertical plates are arranged in parallel. Installation holes are respectively formed in positions with the same height of the two vertical plates, and the rotating shaft 101 is arranged through the two installation holes, so that the rotating shaft 101 is parallel to the bottom plate.

[0046] It should be noted that the support 100 is not limited to the form provided in the embodiment, and those skilled in the art can modify the form of the support 100 according to the actual application scene. For example, when being installed on a fire truck or a fire hydrant, the form of the support 100 can be adjusted in combination with the specific space structure of the vehicle-mounted space or the fire hydrant, as long as the function of supporting the water hose winding device can be realized.

[0047] It is easy to understand that in order to provide power for the water hose winding device, a corresponding driving device such as a driving motor needs to be arranged. In the embodiment, the driving motor is directly connected with the rotating shaft 101 and is installed on the outside of one of the vertical plates. By arranging the driving motor, the automatic winding of the water hose 102 can be realized.

[0048] The first rotating cylinder 110 is installed on the support 100 through the rotating shaft 101. As shown in Figure 1 The first rotating cylinder 110 is formed in a cylindrical structure, and both ends thereof are fixedly connected to the rotating shaft 101 and are adapted to move around the rotating shaft 101 to wind the water hose 102.

[0049] In some embodiments, the first rotating cylinder 110 is formed in a cylinder, and the rotating shaft 101 is arranged at the axis of the cylinder, so that the rotation of the first rotating cylinder 110 is stable.

[0050] In the embodiment, the cross section of the first rotating cylinder 110 perpendicular to the rotating shaft 101 is a regular polygon. Specifically, the first rotating cylinder 110 can be provided in the form of a regular polygonal prism. For example Figure 4As shown, the first rotating cylinder 110 is formed as a regular hexagonal prism, and the rotating shaft 101 is located at the center of the regular hexagonal prism, so that the first rotating cylinder 110 can rotate smoothly, and since each side of the prism is a plane, it is beneficial to the installation and fixation of the first elastic member 130.

[0051] In this embodiment, the two ends of the first rotating cylinder 110 are also formed with circular baffles for preventing the unwinding of the hose 102. On the other hand, the baffles can also be used for the installation of the linkage mechanism 310 and other structures.

[0052] A plurality of first support beams 120 are arranged outside the first rotating cylinder 110 parallel to the rotating shaft 101, for supporting and winding the hose 102.

[0053] The plurality of first support beams 120 are arranged at equal intervals. That is, the plurality of first support beams 120 are evenly arranged outside the first rotating cylinder 110. This is to ensure the smoothness of the hose 102 when it is filled with water in the winding state. It is easy to understand that the more the number of first support beams 120, the closer the shape of the hose 102 to a circle when it is wound, and the distance between each part of the hose 102 and the surface of the first rotating cylinder 110 tends to be consistent, so that more sufficient water filling and expansion space can be obtained. Therefore, if you want to increase the smoothness of the hose 102 when it is filled with water in the winding state, you can appropriately increase the number of first support beams 120.

[0054] In this embodiment, the number of first support beams 120 is equal to the number of sides of the first rotating cylinder 110 along the cross section perpendicular to the rotating shaft 101. For example Figure 4 As shown in the figure, the cross section of the first rotating cylinder 110 perpendicular to the rotating shaft 101 is a regular hexagon, and six first support beams 120 are arranged accordingly. It is easy to understand that the first support beams 120 are arranged one-to-one corresponding to the sides of the regular hexagon, and preferably, the first support beams 120 are arranged at the center of each face of the first rotating cylinder 110. This is beneficial to the stable installation of the first support beams 120 and the smooth water flow of the hose 102 when it is wound.

[0055] As shown in the figure Figure 6 A plurality of first support beams 120 are arranged at equal intervals on the first support beams 120. Preferably, the tooth-shaped grooves are arranged at equal intervals on the first support beams 120.

[0056] The groove shape matches the shape of the water hose 102 in the water-filled state. That is, the water hose 102 can be accommodated in the tooth-shaped groove when the water hose 102 is rolled up, regardless of whether the water hose 102 is in a water-filled state or an empty state. By opening the tooth-shaped groove, not only is it helpful to avoid the water hose 102 from being entangled with each other, but also it creates conditions for the water hose 102 to be rolled up and released in the water-filled state. There is no need to empty the water hose 102 when rolling up, and there is no need to wait for the water hose 102 to be released before being filled with water when in use, which reduces the rolling up and releasing time and meets the emergency fire-fighting demand.

[0057] Specifically, the inner wall of the tooth-shaped groove can be polished to reduce the abrasion of the water hose 102, avoid damage and water leakage of the water hose 102, and at the same time improve the service life of the water hose 102. The bottom of the tooth-shaped groove can be provided in the shape of a circular arc that fits the winding shape of the water hose 102.

[0058] In the embodiment, the opening direction of the groove is at an angle to the plane perpendicular to the rotating shaft 101, that is, the direction of the groove is not parallel to the plane perpendicular to the rotating shaft 101, which plays a certain guiding role for the winding of the water hose 102. By such a setting, the wound water hose 102 is spirally wound in the tooth-shaped groove of the first support beam 120, so that it can be wound neatly, which is conducive to the rapid winding and release of the water hose 102.

[0059] Specifically, when the water hose 102 is wound, it first enters the first tooth-shaped groove of the first support beam 120, and then enters the second tooth-shaped groove of the adjacent second support beam 120, and so on. It is worth mentioning that when one end of the water hose 102 is wound, in order to avoid the other end from producing a large displacement under the action of tension, causing the spiral winding track of the water hose 102 to be damaged, a guide cylinder can be correspondingly provided. The guide cylinder can also play a guiding role when the water hose 102 is released, preventing the hose from being out of control. The water hose 102 passes through the guide cylinder, that is, the water hose 102 is limited by the guide cylinder during winding or releasing, so that it can be wound neatly and released stably.

[0060] The guide cylinder can be installed on the support 100 near the winding end of the water hose 102, or can be fixed at other positions according to the use scene, for example, fixed on a fire truck, which is not limited in the embodiment.

[0061] The first elastic member 130 is connected between the first rotating cylinder 110 and the first support beam 120, and the first elastic member 130 is adapted to be deformed so that the first support beam 120 approaches or moves away from the first rotating cylinder 110.

[0062] As Figure 1In the embodiment shown, the first elastic member 130 is a compression spring, one end of which is mounted on the surface of the first rotating cylinder 110 and is adapted to deform or recover deformation by moving closer to or farther from the first rotating cylinder 110. The bottom of the first support beam 120 is provided with a sleeve, and the other end of the compression spring is arranged in the sleeve. That is, the sleeve is arranged at the connection between the first support beam 120 and the compression spring. In other embodiments, the first elastic member 130 can also be a disc spring or other component that can withstand load and deform flexibly, and the present embodiment is only illustrative and not limited.

[0063] By arranging the first elastic member 130, the first support beam 120 can float relative to the first rotating cylinder 110, thereby being able to stably support the water hose 102 wound outside the first support beam 120. At the same time, through the floating of the first support beam 120, the water hose 102 can be filled with water in the rolled state. When the water hose 102 is filled with water and expands, it will generate a pressure inwardly perpendicular to the rotating shaft 101, and the first support beam 120 will compress the first elastic member 130 under the action of the pressure, thereby moving closer to the first rotating cylinder 110 to provide sufficient space for the expansion of the water hose 102.

[0064] Specifically, when the first rotating cylinder 110 rotates to wind the water hose 102, the water hose 102 is spirally wound in the tooth-shaped groove of the first support beam 120, and the pressure generated causes the first elastic member 130 to elastically deform, and the first support beam 120 moves closer to the first rotating cylinder 110; when the first rotating cylinder 110 reverses to release the water hose 102, the water hose 102 gradually comes out of the tooth-shaped groove of the first support beam 120, and at the same time, the pressure applied to the first elastic member 130 gradually decreases, the deformation of the first elastic member 130 gradually recovers, and the first support beam 120 gradually moves away from the first rotating cylinder 110.

[0065] In actual use, in the process of recovering deformation, the elastic potential energy accumulated by the first elastic member 130 is converted into kinetic energy, which may cause the water hose 102 to be excessively tensioned, affecting the water flow of the water hose 102. Therefore, a fixing ring is arranged outside the sleeve. The fixing ring is provided with a step structure with a height slightly greater than that of the sleeve, and when the first elastic member 130 recovers deformation, the sleeve contacts the step structure, thereby limiting the first support beam 120 from continuing to move away from the first rotating cylinder 110, playing a role of one-way locking and ensuring smooth water flow of the water hose 102.

[0066] In addition, it is worth mentioning that when the water hose 102 is wound while being filled with water, in order to prevent the curvature of the water hose 102 from being too large to cause local water flow failure, the winding diameter of the water hose 102 needs to be reasonably set.

[0067] In combination with Figure 4It is known that the winding diameter of the water hose 102 is approximately equal to the sum of the diameter of the first rotating cylinder 110 and the height of the two opposite first support beams 120. It has been verified by experiments that when the winding diameter of the water hose 102 is not less than 1 meter, the water hose 102 can be smoothly filled with water in the winding state. Therefore, in actual production, the diameter of the first rotating cylinder 110 and the height of the first support beam 120 can be reasonably set in combination with this value.

[0068] In order to more stably install and support the first support beam 120, a plurality of first elastic members 130 are correspondingly connected to each of the first support beams 120 and are arranged at intervals along the length direction of the rotating shaft 101. In the embodiment, two first elastic members 130 are correspondingly arranged on each of the first support beams 120 and are arranged at intervals along the direction of the rotating shaft 101, so as to uniformly bear the pressure caused by the winding of the water hose 102 and improve the strength of the first support beam 120. In other embodiments, three or more first elastic members 130 can be correspondingly arranged between each of the first support beams 120 and the first rotating cylinder 110, and preferably, the plurality of first elastic members 130 are arranged at equal intervals, so as to optimize the supporting effect of the first support beam 120.

[0069] In order to achieve the same purpose as described above, the first elastic member 130 can also be arranged at other positions. For example, the two ends of the first support beam 120 can be connected to the baffles on the two sides of the first rotating cylinder 110 through the first elastic member 130. In this case, when the first support beam 120 moves close to the first rotating cylinder 110 under the action of the pressure of the water hose 102, the first elastic member 130 deforms under the action of the shearing force, and the elastic force generated thereby can also help the first support beam 120 to return to the original position after the pressure decreases.

[0070] As shown in FIG. 2, Figures 2 to 3 As shown in FIG. 2,

[0071] Specifically, the second rotating cylinder 210 is arranged outside the first support beam 120 and is mounted on the support 100 along the rotating shaft 101. By adding the second rotating cylinder 210, the length of the water hose 102 that can be wound by the water hose winding device can be increased.

[0072] It is easy to understand that the water hose 102 is preferentially wound on the inner first rotating cylinder 110. When the water hose 102 wound on the first rotating cylinder 110 reaches a certain limit, the outer second rotating cylinder 210 starts to work and continues to wind the water hose 102. Therefore, as shown in the figure, at least one opening 213 is formed on the second rotating cylinder 210, so that the water hose 102 can pass through the opening 213 into the inner layer and be wound by the first rotating cylinder 110. Figure 4

[0073] It is worth mentioning that the distance between the inner wall of the second rotating cylinder 210 and the first rotating cylinder 110 is slightly larger than the height of the first support beam 120. By such arrangement, on the one hand, it does not affect the water hose 102 entering the groove of the first support beam 120, and on the other hand, it can avoid the free end of the water hose 102 from being greatly deviated under the action of tension, which is beneficial to winding the water hose 102 on the first support beam 120 according to the set spiral trajectory.

[0074] In order to facilitate the installation of the second rotating cylinder 210, in the embodiment, the second rotating cylinder 210 is arranged in a split connection form. The second rotating cylinder 210 includes a first support part 211 and a second support part 212 which are detachably connected. The first support part 211 and the second support part 212 can be connected by fasteners, or can be connected by buckling, gluing and the like. The embodiment does not make specific limitation on this, as long as the purpose of forming the second rotating cylinder 210 by cooperating the first support part 211 and the second support part 212 can be achieved. Preferably, the opening 213 through which the water hose 102 passes can be arranged between the first support part 211 and the second support part 212, so as to omit the opening step and save the process cost. It is easy to understand that the second rotating cylinder 210 is rotatably connected with the rotating shaft 101.

[0075] Similarly to the first rotating cylinder 110, the second rotating cylinder 210 can be formed as a cylinder, or can be arranged in a form of a regular polygon in a cross section perpendicular to the rotating shaft 101. For example Figure 4 As shown in the figure, the second rotating cylinder 210 is formed as a regular hexagonal prism and is coaxially arranged with the first rotating cylinder 110, so that the second rotating cylinder 210 can rotate smoothly, and the installation of the second elastic member 230 is more stable. The two ends of the second rotating cylinder 210 are also formed with circular baffles for preventing the wound water hose 102 from falling out.

[0076] ​Similar to the positional relationship between the first support beam 120 and the first rotating cylinder 110, a plurality of second support beams 220 are arranged outside the second rotating cylinder 210, and the plurality of second support beams 220 are parallel to the rotating shaft 101 and uniformly arranged on the surface of the second rotating cylinder 210, for supporting and winding the water hose 102. In the case where the second rotating cylinder 210 is formed in a prism shape, the number of the second support beams 220 can be equal to the number of the edges of the cross section of the second rotating cylinder 210 perpendicular to the rotating shaft 101. For example Figure 4 As shown in FIG. 2, the cross section of the second rotating cylinder 210 perpendicular to the rotating shaft 101 is a regular hexagon, and six second support beams 220 are arranged correspondingly. The second support beams 220 are arranged one by one corresponding to the edges of the regular hexagon, and preferably, the second support beams 220 are arranged at the centers of each face of the second rotating cylinder 210.

[0077] The plurality of second support beams 220 are each provided with tooth-shaped grooves. Preferably, the tooth-shaped grooves are arranged at equal intervals on the second support beams 220. The function of the tooth-shaped grooves and the arrangement of the direction of the grooves are the same as described above, and will not be described here. Preferably, the angle of the tooth-shaped grooves on the second support beams 220 is consistent with that of the first support beams 120, and the spiral direction is opposite to that of the first support beams 120, so that the water hose 102 can be smoothly and continuously wound.

[0078] The second elastic member 230 is connected between the second rotating cylinder 210 and the second support beam 220, and the second elastic member 230 is adapted to be deformed so that the second support beam 220 approaches or moves away from the second rotating cylinder 210.

[0079] Similar to the first elastic member 130, the second elastic member 230 can also be a component that can be flexibly deformed, such as a compression spring or a disc spring, and is installed through a sleeve arranged at the bottom of the second support beam 220, and is one-way locked through a fixing ring arranged outside the sleeve, so that the second support beam 220 can move towards the second rotating cylinder 210 or return to the original position, thereby being able to stably support the water hose 102 wound outside the second support beam 220, and being able to fill the water hose 102 in the wound state. Each of the second support beams 220 is correspondingly connected with a plurality of second elastic members 230 arranged at intervals along the length direction of the rotating shaft 101, and the number and interval of the second elastic members 230 can be set by the person skilled in the art according to the actual situation.

[0080] According to the water hose winding device provided by the present application, the water hose winding device further comprises a linkage mechanism 310, and in the triggered state of the linkage mechanism 310, the second rotating cylinder 210 is adapted to rotate synchronously with the first rotating cylinder 110 through the linkage mechanism 310.

[0081] As Figure 5As shown, in this embodiment, the linkage mechanism 310 is formed by a plug 311 arranged on the second rotating cylinder 210 and a slot 312 arranged on the rotating shaft 101. When the hose 102 wound on the first rotating cylinder 110 reaches a certain limit, the plug 311 on the second rotating cylinder 210 is triggered to be inserted into the slot 312, so as to transmit the torque of the first rotating cylinder 110 to the second rotating cylinder 210, and drive the second rotating cylinder 210 to rotate synchronously. It can be understood that, in order to achieve this purpose, a controller, a sensor and other elements need to be arranged correspondingly to monitor the hose 102 wound on the first rotating cylinder 110 and determine the timing at which the second rotating cylinder 210 starts to work. For example, the length of the hose 102 wound by the hose winding device can be identified by a sensor, and when the length reaches a preset value, the plug 311 is controlled to be ejected and inserted into the slot 312 to start the second rotating cylinder 210.

[0082] In this embodiment, the hose interface 320 is arranged at least at one end of the rotating shaft 101. A proximity switch is arranged at the end of the first rotating cylinder 110 away from the hose interface 320. The hose 102 is wound on the first support beam 120 from one end of the hose interface 320, and gradually fills the first support beam 120 in a spiral shape. When the hose is wound to the end away from the hose interface 320, that is, the end of the hose wound on the first support beam 120, the proximity switch arranged on the baffle of the first rotating cylinder 110 is identified, and the controller reads this signal through electrical connection, and then controls the plug 311 on the second rotating cylinder 210 to be inserted into the slot 312. That is, the linkage mechanism 310 is started in response to the proximity switch. The advantage of this arrangement is that the timing at which the second rotating cylinder 210 starts to work is more accurate, and there is no need to calculate and input the preset value of the length of the hose 102 wound, thereby reducing the design workload.

[0083] During the process of inserting the plug 311 into the slot 312, the controller can control the driving motor to stop running to ensure that the plug 311 can be accurately inserted. In addition, in order to enable the plug 311 to be accurately inserted into the slot 312, a sensor can be correspondingly arranged on the ejection mechanism of the plug 311 to identify the position of the slot 312. The person skilled in the art can select the arrangement mode of the controller and the sensor according to the actual situation, and the present embodiment does not limit this.

[0084] In some embodiments, the plug 311 can also be arranged on the rotating shaft 101, and the slot 312 can be arranged on the second rotating cylinder 210. Alternatively, the linkage mechanism 310 can also be arranged in other forms, for example, an electromagnet arranged on the first rotating cylinder and triggered in response to the hose filled on the first support beam 110 can magnetically attract the second rotating cylinder, so as to enable the second rotating cylinder 210 to rotate synchronously with the first rotating cylinder 110 through the linkage mechanism 310.

[0085] According to the present invention, a hose winding device further includes a hose interface 320 disposed at at least one end of the rotating shaft 101.

[0086] like Figure 5 As shown, the water hose 102 can be connected to the device through the water hose interface 320 located at the end of the rotating shaft 101, and then sequentially completes the winding work on the first support beam 120 and the second support beam 220. Finally, it connects to a nozzle or other emergency firefighting equipment such as a drone from the outside of the second support beam 220. In other words, the water hose interface 320 is used to fix one end of the water hose 102 so that the first support beam 120 and the second support beam 220 can wind the water hose 102; it is also used to connect to the water supply mechanism to supply water to the water hose 102 in the device to achieve the firefighting purpose.

[0087] The hose connector 320 is formed as a rotary joint. A rotary joint is a mechanical connector used to connect two components and allow them to rotate in different directions. This design allows the two components to rotate relative to each other without disassembling the connection.

[0088] With the above design, when the water hose 102 is wound, the inner side of the water hose interface 320 and the water hose 102 connected thereto rotate synchronously with the first rotating drum 110 and the second rotating drum 210, while the water hose 102 on the outer side of the water hose interface 320, which is used to connect to the water supply mechanism, remains stationary, thereby avoiding excessive twisting of the water hose 102 itself and affecting the smooth flow.

[0089] Understandably, the inner side of the hose connector 320 is connected in series with the rotating shaft 101 and can rotate with the rotating shaft, while the outer side of the hose connector 320 is fixed relative to the bracket 100. The hose 102 can be connected to the hose connector 320 through the interface on the rotating shaft.

[0090] The installation, winding, and release process of the hose reel winding device provided in the second aspect embodiment of the present invention will be described below:

[0091] When installing the hose, connect one end of the hose 102 to the side of the hose connector 320 closest to the rotating shaft 101, and pull it to the outside of the hose reel through the opening 213. If the bracket 100 is equipped with a guide tube, the hose 102 can be passed through the guide tube to provide some guidance during subsequent reeling. The side of the hose connector 320 away from the rotating shaft 101 can be connected to the water supply mechanism via another hose 102 for easy access.

[0092] When winding, the driving motor drives the first rotating cylinder 110 to start rotating to wind the water hose 102. The water hose 102 enters the inner layer from the outer layer through the opening 213, enters the first toothed groove of the first support beam 120, and then sequentially and orderly enters the second toothed groove of the second first support beam 120, the third toothed groove of the third first support beam 120, and so on, and is spirally wound until the first support beam 120 is fully covered. At this time, the proximity switch arranged on the baffle of the first rotating cylinder 110 recognizes that the water hose 102 is close to the baffle, that is, the water hose 102 is wound to the end of the first rotating cylinder 110, and feeds back the signal to the controller. The controller stops the driving work of the driving motor in response to the signal, and starts the insertion plate 311 on the second rotating cylinder 210 to be inserted into the insertion slot 312. The sensor arranged on the insertion slot 312 recognizes that the insertion plate 311 is inserted, and feeds back the signal to the controller. The controller controls the driving motor to resume work, drives the first rotating cylinder 110 to rotate through the driving rotating shaft 101, and at the same time, the first rotating cylinder 110 transmits the torque to the second rotating cylinder 210 through the linkage mechanism 310, so that the second rotating cylinder 210 rotates synchronously with the first rotating cylinder 110, thereby winding the water hose 102 on the second support beam 220. The water hose 102 is spirally wound on the outside of the second support beam 220 in a similar manner as described above, until the second support beam is fully covered.

[0093] Alternatively, when starting to install the water hose 102, the second winding rotating cylinder 210 can not be arranged, and when the water hose is fully covered on the first support beam 120, the first support part 211 and the second support part 212 are matched to form the second rotating cylinder 210, the linkage mechanism 310 is triggered, and the winding of the outer water hose 102 is continued.

[0094] When releasing, the driving motor can stop working, and the firefighters release the water hose by pulling the free end of the outer water hose 102; or the driving motor drives the rotating shaft 101 to rotate reversely to release the water hose 102. It is easy to understand that, contrary to the winding process, after the outer water hose 102 is completely released, the inner water hose 102 continues to be released through the opening 213. The water hose 102 always passes through the guide cylinder when being released, so that the release is more stable.

[0095] The embodiment of the present application also provides a fire-fighting equipment comprising the water hose winding device as described above.

[0096] By setting in this way, the water hose 102 can be rolled in the tooth-shaped groove of the water hose rolling device in the absence of fire fighting demand, realizing the space saving; when fire occurs, the tooth-shaped groove has a certain accommodating space, which is enough to accommodate the water hose 102 in the water-filled state, and the first support beam 120 and the second support beam 220 have the floating function, which provides space for the expansion of the water hose along the radial direction of the first rotating cylinder 110 and the second rotating cylinder 210, so that the release work and the water filling work of the water hose 102 can be carried out synchronously without waiting for the water hose 102 to be completely released before water filling, thereby better meeting the demand of emergency fire fighting.

[0097] Specifically, the fire fighting equipment is a fire fighting vehicle, and the water hose rolling device is arranged in the compartment of the fire fighting vehicle. The current fire fighting vehicle is provided with a special water hose storage space, and the water hose is released and rolled by manual mode, which is inconvenient to operate, and the water hose cannot be filled with water in the rolled state. In order to solve this problem, an automatic water hose rolling device is arranged, which facilitates the rolling and releasing operation of the water hose 102, and enables the release work and the water filling work of the water hose 102 to be carried out synchronously without waiting for the water hose 102 to be completely released before water filling, thereby better meeting the demand of emergency fire fighting. In addition, by rolling the water hose 102 on the water hose rolling device, the compartment space and the accessory configuration can be saved, and the compartment layout can be optimized.

[0098] As an embodiment, in the case of fire in hilly, forest and other terrains or high places difficult for people to reach, the fire fighting equipment provided by the embodiment of the application can be used in cooperation with the unmanned aerial vehicle to carry out fire fighting operation.

[0099] The current unmanned aerial vehicle needs to first completely spread the water hose 102 on the ground before carrying out fire fighting operation, and then flies to a high place by connecting the water outlet end of the water hose 102 to pour water into the fire site. However, at this time, the water hose 102 spread on the ground may be wound, bent, stacked and the like, and then when the water hose 102 is filled with water, the water flow may be squeezed and blocked at the above-mentioned places, affecting the reliability of water supply, and even may miss the fire extinguishing opportunity, causing the fire to expand.

[0100] To solve the above problems, in the embodiment, the fire-fighting equipment and the unmanned aerial vehicle are used to cooperate in fire extinguishing. Specifically, a connecting structure is arranged on the unmanned aerial vehicle, which is used to connect the water outlet end of the water hose 102; a corresponding sensor is arranged, which is used to detect and feedback the flight information of the unmanned aerial vehicle, such as the flight height, the angle deviating from the top of the fire-fighting equipment, etc., or the flight information of the unmanned aerial vehicle is obtained through the central control system; a corresponding controller and driving mechanism are arranged, which are used to control the rotation of the first rotating cylinder 110 and the second rotating cylinder 210 based on the flight information of the unmanned aerial vehicle, so as to control the length of the water hose 102 released; a corresponding guide structure is arranged, for example, the guide cylinder described above, the water hose 102 is connected to the unmanned aerial vehicle after passing through the guide cylinder after being released from the fire-fighting equipment, so as to avoid the influence of the too large pressure on the stable release of the water hose 102.

[0101] Through the above arrangement, the effect that can be achieved is that on the one hand, the tooth-shaped groove has a certain accommodation space, which is enough to accommodate the water hose 102 in the water-filled state, and the first supporting beam 120 and the second supporting beam 220 have a floating function, which provides space for the expansion of the water hose along the radial direction of the first rotating cylinder 110 and the second rotating cylinder 210, so that the water hose 102 can also be filled with water in the rolled state, saving the valuable time of fire fighting operation.

[0102] On the other hand, as the unmanned aerial vehicle ascends or descends, the length of the required water hose 102 changes accordingly. The fire-fighting equipment provided in the embodiment responds to this change, controls the rotation of the first rotating cylinder 110 and the second rotating cylinder 210 according to the length of the water hose 102 required by the unmanned aerial vehicle, so that the water hose 102 is orderly rolled or released in the fire-fighting equipment according to the set spiral track, so as to ensure that the length of the water hose 102 released is appropriate, and avoid the occurrence of conditions such as winding, bending and stacking of the water hose during release, so as to ensure smooth water flow and facilitate the recovery of the water hose.

[0103] The fire-fighting equipment provided in the embodiment can also be used in cooperation with other equipment for fire-fighting operation, and the specific mode is referred to the above embodiment and is adjusted according to the working mode of the related equipment, which will not be repeated here.

[0104] The fire-fighting equipment can also be a fire hydrant, and the water hose winding device is arranged in the space of the fire hydrant or near the fire hydrant. The current fire hydrant is provided with a separate water hose and a water supply port, and when in use, the water hose needs to be manually taken down, released, connected to the water supply port, and the water supply valve is opened, and the like. If the user is a non-professional person, the facility will not be familiar, the use will not be smooth, the operation will be wrong, and the like, and the fire extinguishing opportunity will be delayed. In order to solve this problem, the water hose winding device of the fire hydrant can be arranged in or near the fire hydrant through the support 100, and the water hose interface 320 is connected to the water supply port. When in use, only the required length of the water hose 102 needs to be released from the water hose winding device, and the water supply valve is opened to start using, without complicated operation steps, which is beneficial to the operation of non-professional persons and professional persons, and also avoids the time and strict use requirements of the traditional water hose release.

[0105] It should be noted that the water hose winding mechanism described in the present application is not limited to the single-layer structure and the two-layer structure involved in the above two embodiments, and a rotating cylinder can also be added in the outer layer accordingly to wind a larger length of water hose 102. In addition, the length and diameter of the rotating cylinder can also be adaptively adjusted according to the installation space and the length of the water hose 102.

[0106] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
