[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] The purpose of the present invention is to provide a water hose winding and unwinding device to solve the problems existing in the above-mentioned prior art, improve the efficiency of water hose winding and unwinding, and facilitate the work of winding and unwinding the water hose.

[0044] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] As Figures 1 to 13 shown, this embodiment provides a water hose winding and unwinding device, including:

[0046] Mobile vehicle 1;

[0047] The retracting and releasing mechanism includes a first driving device 6, two clamping mechanisms and a plurality of clip groups; the first driving device 6 is fixedly mounted on the mobile vehicle 1; the two clamping mechanisms are symmetrically mounted on the mobile vehicle 1, each clamping mechanism includes a push-pull quick clamp 26, the push-pull quick clamp 26 is rotationally matched with the body of the mobile vehicle 1, the push-pull rods 27 of the two push-pull quick clamps 26 are coaxial, each clip group includes two clips (respectively a first clip 9 and a second clip 30) which can be detachably connected to the output ends of the two push-pull quick clamps 26, and the two clips mounted on the output ends of the two push-pull quick clamps 26 are arranged opposite to each other, the two clips in each clip group are used to clamp the water hose head, and the sizes of the water hose heads corresponding to different clip groups are different; the first driving device 6 is transmission-connected to the push-pull rod 27 of a push-pull quick clamp 26;

[0048] The auxiliary lifting belt includes two press-lock straps 12 arranged in parallel and at intervals and a connecting belt 13 arranged between the two press-lock straps 12. The two press-lock straps 12 are respectively fixedly connected to the connecting belt 13. The material of the connecting belt 13 is the same as that of the water hose. Flexible handles 14 are respectively arranged on the two press-lock straps 12. The auxiliary lifting belt is used to wrap the rolled water hose.

[0049] Definition: The hose head is a part used to connect to the end of the hose to facilitate the reeling of the hose, and is usually cylindrical in shape.

[0050] Since the first clamp 9 and the second clamp 30 are both detachable from the output end of the push-pull quick clamp 26, by replacing the first clamp 9 and the second clamp 30 corresponding to the water hose head (that is, replacing the clamp group corresponding to the water hose head), it is possible to clamp water hose heads of different sizes, that is, to retract and release water hoses of different calibers, which greatly improves the applicability of the device and solves the problem that the existing equipment can only retract water hoses of a single caliber; the retracted water hose can be wrapped by the auxiliary lifting belt, which is convenient for the operator to lift it out after the water hose is retracted, significantly reducing the labor intensity and improving the convenience of the retraction and release work.

[0051] The arrangement of the two push-pull quick clamps 26 facilitates adjusting the distance between the first clamp 9 and the second clamp 30 so that the first clamp 9 and the second clamp 30 can clamp or release the hose head.

[0052] In the optional scheme of this embodiment, it is more preferred that the bottom of the mobile vehicle 1 is equipped with mobile wheels, and the mobile wheels include at least one driving wheel 4 and at least one universal wheel 5, and the sum of the number of the driving wheels 4 and the universal wheels 5 is greater than or equal to 3;

[0053] The mobile vehicle 1 is provided with a second driving device 10, which is used to drive the driving wheel 4 to rotate;

[0054] The mobile vehicle 1 is provided with a handrail 2, on which a second control switch for controlling the opening and closing of the second drive device 10 and a second speed regulator 3 for adjusting the output speed of the second drive device 10 are provided. The combined design of the moving wheels enables the mobile vehicle 1 to have good maneuverability and steering flexibility, and can move freely in complex terrain. The second drive device 10 cooperates with the second control switch and the second speed regulator 3, so that the operator can flexibly control the travel speed and start and stop of the mobile vehicle 1 according to actual conditions, and the operation is simple.

[0055] In the optional scheme of this embodiment, preferably, the first driving device 6 and the second driving device 10 are both motors, and the second speed regulator 3 is a handlebar-type speed regulator with a cruise control function; the use of the handlebar-type speed regulator further improves the convenience and accuracy of speed regulation. The battery power supply ensures the independent operation of the device without being restricted by an external power supply.

[0056] The mobile vehicle 1 is provided with a storage box 7, in which a battery is provided, and the battery is used to power the first drive device 6 and the second drive device 10.

[0057] In this embodiment, the specific scheme for realizing transmission between the first driving device 6 and the clamping mechanism is as follows:

[0058] The mobile vehicle 1 is provided with a transmission shaft 23 corresponding to the push-pull quick clamp 26 one by one. The transmission shaft 23 is hollow and rotates with the body of the mobile vehicle 1.

The fixing blocks 29 and the corresponding axial long grooves 28 are in sliding fit along the axial direction of the push-pull rod 27 and are limitedly connected along the width direction of the axial long grooves 28. Through the cooperation of the axial long grooves 28 and the fixing blocks 29, the push-pull rod 27 of the push-pull type quick clamp 26 is in axial sliding fit and circumferentially limited connection with the corresponding transmission shaft 23. A bearing seat 25 corresponding to the transmission shaft 23 is provided on the vehicle body of the mobile vehicle 1, and the transmission shaft 23 is rotationally matched with the corresponding bearing seat 25 through a bearing 24. The clamping piece is detachably connected to the output end of the push-pull type quick clamp 26 through a connecting pin 34. Connecting holes are provided on both the clamping piece and the output end of the push-pull type quick clamp 26 corresponding to the connecting pin 34, so that the connecting pin 34 passes through the connecting hole on the clamping piece and the connecting hole on the output end of the push-pull type quick clamp 26 at the same time, realizing the detachable connection between the clamping piece and the output end of the push-pull type quick clamp 26. It should be noted that limit pieces should be provided at both ends of the connecting pin 34 after the connection is completed to prevent the connecting pin 34 from disengaging from the connecting hole during the working process.

[0061] It should be noted that the push-pull type quick clamp 26 is a commercially available product well-known to those skilled in the art. In this embodiment, the specific structure and working principle of the push-pull type quick clamp 26 will not be elaborated further; in this embodiment, two clamping pieces in the clamping piece group are pushed and pulled by two push-pull type quick clamps 26 to realize the clamping and loosening of the water head. In addition, in this embodiment, a fixing ring 33 and a limit chain 31 are provided on each push-pull type quick clamp 26. One end of the limit chain 31 is connected to the fixing ring 33 and the other end is connected to the handle 32 to fix the position of the handle 32 and prevent the position of the handle 32 of the push-pull type quick clamp 26 from deviating accidentally during the rotation of the two push-pull type quick clamps 26.

[0062] In an alternative embodiment of this embodiment, preferably, a braking control system 11 is further provided on the mobile vehicle 1, and the braking control system 11 is used to brake the drive wheels 4; the braking control system 11 is a very mature existing technology in the vehicle field, so the specific structure and working principle of the braking control system 11 will not be elaborated further in this embodiment. The braking control system 11 can brake the drive wheels 4 in time to ensure the stability and safety of the mobile vehicle 1 when it stops.

[0063] In an alternative embodiment of the present embodiment, preferably, the armrest 2 is rotatably connected to the vehicle body, and a plurality of adjustment holes 19 are provided on the vehicle body and are circumferentially distributed along the rotation axis between the armrest 2 and the vehicle body. A positioning pin 20 is provided on the armrest 2, and the positioning pin 20 can be inserted into any one of the adjustment holes 19. The design of the adjustment holes 19 facilitates the adjustment of the angle and height of the armrest 2, meets the usage requirements of operators of different heights, and improves the comfort and convenience of operation.

[0064] In an alternative embodiment of the present embodiment, preferably, both the first clamping piece 9 and the second clamping piece 30 are provided with clamping grooves for clamping with the water belt head, that is, both the first clamping piece 9 and the second clamping piece 30 are clamped with the water belt head. It is not easy for the first clamping piece 9 and the second clamping piece 30 to rotate relative to the water belt head, that is, the phenomenon of slipping, which improves the stability of the water belt winding and unwinding process.

[0065] In an alternative embodiment of the present embodiment, preferably, the winding and unwinding mechanism further includes a guiding mechanism, the guiding mechanism is arranged at the front end of the mobile vehicle 1, and the clamping mechanism is arranged in the middle of the mobile vehicle 1;

[0066] The guiding mechanism includes a transverse roller 15 and two vertically arranged rollers 16 spaced apart. The transverse roller 15 is rotationally matched with the mobile vehicle 1; a plurality of mounting holes are provided on the mobile vehicle 1 on one side of the transverse roller 15 close to the rear end of the mobile vehicle 1, and all the mounting holes are spaced apart along the first direction, and the first direction is parallel to the axial direction of the transverse roller 15; the vertical roller 16 includes a roller body and a fixing rod fixedly connected to the roller body, and the fixing rod can be installed in any one of the mounting holes; the transverse roller 15 and the vertical roller 16 of the guiding mechanism cooperate with each other, and can play a good guiding role in the water belt when it enters the winding and unwinding device, ensuring that the water belt can accurately and smoothly enter the winding and unwinding mechanism for winding. The setting of the mounting holes enables the position of the vertical roller 16 to be flexibly adjusted according to the actual width of the water belt, improves the adaptability of the guiding mechanism to water belts of different specifications, ensures the guiding effect, and reduces the possibility of problems such as winding and twisting of the water belt during the winding and unwinding process.

[0067] In an alternative embodiment of the present embodiment, preferably, the winding and unwinding mechanism further includes a pressing and draining mechanism, and the pressing and draining mechanism is located between the vertical roller 16 and the clamping mechanism; the pressing and draining mechanism includes a supporting roller 17 and a pressing and draining roller 18. The supporting roller 17 is located below the pressing and draining roller 18 and is installed on the mobile vehicle 1. The supporting roller 17 is used for rolling cooperation with the bottom surface of the water belt, and the pressing and draining roller 18 is used for rolling cooperation with the top surface of the water belt; the pressing and draining mechanism can perform pressing and draining operations on the water belt before winding, effectively reducing the residual water in the water belt, reducing the weight and volume of the water belt after winding, and facilitating subsequent handling and storage. The rolling cooperation design of the supporting roller 17 and the pressing and draining roller 18 not only ensures the pressing and draining effect on the water belt, but also avoids excessive wear on the water belt.

[0068] In an alternative embodiment of the present embodiment, preferably, limiting rotating rods 35 are respectively arranged at both ends of the pressure and drainage roller 18, and placing grooves 36 are arranged on the moving vehicle 1 corresponding to each limiting rotating rod 35. The limiting rotating rod 35 can be placed in the corresponding placing groove 36. The arrangement of the limiting rotating rod 35 and the placing groove 36 facilitates the removal of the pressure and drainage roller 18 when the pressure and drainage operation is not required, without affecting the normal operation of other devices, and also facilitates the maintenance and servicing of the pressure and drainage roller 18.

[0069] In an alternative embodiment of the present embodiment, preferably, an LED lighting lamp 8 is further arranged on the armrest 2.

[0070] The method of using the hose winding and unwinding device of the present embodiment for winding the hose is as follows:

[0071] (1) Preparation work:

[0072] Determine the size of the hose to be wound to determine the size of the hose head, and select the corresponding first clip 9 and second clip 30; install the first clip 9 on the output end of a push-pull type quick clamp 26 to ensure firm installation; similarly, install the second clip 30 on the output end of another push-pull type quick clamp 26, and make the first clip 9 and the second clip 30 arranged oppositely;

[0073] Move the moving vehicle 1 to the hose winding operation site, and control the movement of the moving vehicle 1 through the second driving device 10 according to the actual terrain and operation requirements, and adjust it to a suitable position; then use the braking control system 11 to brake the driving wheels 4 to prevent the moving vehicle 1 from moving during the operation;

[0074] Adjust the position of the armrest 2 according to the operator's height, rotate the armrest 2 to a suitable angle, insert the positioning pin 20 into the corresponding adjustment hole 19 on the vehicle body to fix the position of the armrest 2, so that the operator can operate comfortably;

[0075] Adjust the position of the vertical roller 16 in the guiding mechanism according to the width of the hose, insert the fixing rod of the vertical roller 16 into a suitable installation hole on the moving vehicle 1, so that the distance between the two vertical rollers 16 is adapted to the width of the hose, and ensure that the hose can pass smoothly between the two vertical rollers 16 and be guided;

[0076] Fixing the starting end of the hose: Connect the starting end of the hose to be wound to the hose head, and then place the hose head between the first clip 9 and the second clip 30, so that the first clip 9 and the second clip 30 clamp the hose head, and ensure that the first clip 9 and the second clip 30 firmly clamp the hose head to prevent slipping during the winding process.

[0077] In addition, if there is water in the hose to be rolled up and it is necessary to drain the water by pressure, a drainage roller 18 needs to be provided so that the drainage roller 18 is pressed on the hose to be rolled up;

[0078] (2) Rolling and Rewinding:

[0079] The first driving device 6 is turned on. Since the first driving device 6 is connected to the push-pull rod of a push-pull quick clamp 26, the first driving device 6 can drive the clamping mechanism to rotate, so that the first clamping piece 9 and the second clamping piece 30 that clamp the hose head start to rotate, driving the hose head to rotate, thereby performing the hose winding operation;

[0080] During the reeling process, the horizontal roller 15 and the vertical roller 16 guide the hose so that it can neatly enter the reeling mechanism for reeling. The operator needs to observe the hose passing through the guide mechanism to ensure that the hose has no deviation, entanglement or other abnormalities.

[0081] If a pressure drainage drum 18 is provided, the lifting drum 17 supports the bottom surface of the hose, and the pressure drainage drum 18 applies pressure to the top surface of the hose to achieve pressure drainage during the movement of the hose. The operator needs to pay attention to the pressure drainage effect to ensure that the water is effectively discharged;

[0082] When the hose is nearly rolled up, prepare the auxiliary lifting belt; arrange the two parallel and spaced buckle straps 12 and the connecting belt 13 so that they can smoothly wrap the rolled up hose.

[0083] (3) Hose removal

[0084] When the water hose is completely reeled up, turn off the first driving device 6 to stop the two push-pull quick clamps 26 and the two clips from rotating; then take out the drainage drum 18, lay the auxiliary lifting belt under the reeled water hose, and then operate the two push-pull quick clamps 26 to release the clamping of the water hose head by the first clip 9 and the second clip 30, and the assembly of the reeled water hose and the water hose head falls on the auxiliary lifting belt, and then pass the two buckle straps 12 in the auxiliary lifting belt around the reeled water hose and buckle them, so that the connecting belt 13 and the two buckle straps 12 fit tightly against the water hose, as shown in the figure, and then the operator takes the reeled water hose out of the mobile vehicle 1 through the flexible handle 14 to complete the water hose retracting and releasing operation.

[0085] The method of using the hose retracting and unretracting device of this embodiment to lay the hose is as follows:

[0086] The hose head of the rolled-up hose is clamped by the first clamp 9 and the second clamp 30, and then the staff holds the free end of the hose, and then controls the clamping mechanism and the hose head to rotate by the first driving device 6 to gradually release the hose.

[0087] In the present invention, specific examples are used to illustrate the principles and implementation manners of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
