Description

Technical Field

[0001] The present invention relates to a sanitation vehicle with an automatic reel device, belonging to the technical field of sanitation vehicles. Background Art

[0002] With the country's increasing emphasis on environmental protection, sanitation vehicles have become indispensable equipment for urban sanitation. In sanitation operations, especially in tasks such as cleaning and high-pressure cleaning, hoses are widely used as key auxiliary tools. Most sanitation vehicles are equipped with reel devices for winding and unwinding hoses during long-distance operations to ensure the smooth progress of the operation process. The winding design of the hose can effectively prevent the hose from becoming scattered, reducing potential safety hazards such as tripping and damage, and ensuring the cleanliness and safety of the operation area.

[0003] However, most of the current reel devices on the market still use manual rotation to control the winding and unwinding of the hose. Manual operation is not only time-consuming and laborious, but also due to the lack of intelligent management, the recycling of the hose is often chaotic, prone to knotting and winding, resulting in a shortened service life of the hose, and it is also not convenient for later storage and maintenance. This manual operation method seriously affects work efficiency and brings a greater labor intensity to the operators, further affecting the overall effect of the operation.

[0004] Based on these problems, we need to design an intelligent, efficient and easy-to-operate hose winding device. This device should be able to achieve the control of hose winding and unwinding through automation technology, avoid the inconvenience caused by manual operation, and at the same time ensure the neat and efficient storage of the hose, reducing the risk of hose damage. The design goal is to improve the operation efficiency of the device, reduce the labor intensity of the operators, extend the service life of the hose, and improve the overall efficiency of sanitation operations. With the country's increasing emphasis on environmental protection, sanitation vehicles have become indispensable equipment for urban sanitation. Most sanitation vehicles are equipped with reel devices for storing hoses for long-distance operations.

[0005] Currently, the reel devices on the market generally use manual rotation to control the winding and unwinding of the hose. Manual operation is time-consuming and laborious, and the hose is wound messily during recycling, which is not convenient for storing the hose. Summary of the Invention

[0006] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a sanitation vehicle with an automatic reel device to solve the problems of the existing technology.

[0007] To achieve the above purpose, the present invention is realized through the following technical solutions:

[0008] A sanitation vehicle with an automatic reel device includes: a base fixedly installed on the vehicle body, a reel cylinder rotatably installed on the base, a first driving component for driving the reel cylinder to rotate, and a hose wound around the reel cylinder;

[0009] A set of rotating cylinders for clamping and positioning the rubber hose up and down, guide blocks for rotatably mounting the rotating cylinders, and a second driving assembly for driving the guide blocks to move horizontally left / right. The second driving assembly receives the power of the first driving assembly;

[0010] A control module, which is electrically connected to the first driving assembly;

[0011] The rotating cylinder is located on the side of the hose reel cylinder facing the water outlet end of the rubber hose, and the rotating cylinder is arranged parallel to the hose reel cylinder;

[0012] The control module controls the start of the first driving assembly. The first driving assembly drives the hose reel cylinder to wind up the rubber hose. The second driving assembly controls the left and right reciprocating movement of the guide block. The rotating cylinder drives the rubber hose to adjust the winding position on the hose reel cylinder from left to right / from right to left;

[0013] Wherein, the internal water flow of the rubber hose is discharged by the extrusion of the two rotating cylinders.

[0014] As a further improvement, it further includes an adjusting assembly for driving the two rotating cylinders to move up and down. The adjusting assembly includes a group of adjusting pieces installed on both sides of the rotating cylinder through a rotating shaft. The adjusting pieces are bent outward to form a first installation part, and bolts are installed on the first installation part;

[0015] A vertically arranged support piece. Corresponding to the bolt area on the support piece, a guiding slot hole is vertically arranged. The bolt is inserted into the guiding slot hole, and a nut is arranged on the side of the support piece away from the bolt. The bolt and the adjusting piece move up / down in the guiding slot hole, and are fixed through the cooperation of the bolt and the nut to adjust the distance between the two rotating cylinders corresponding to the diameter of the rubber hose.

[0016] As a further improvement, a rack is arranged on one side of the guiding slot, a toothed ring is rotatably sleeved on the bolt, the toothed ring matches the rack, and markings are arranged on the support piece corresponding to the number of teeth of the rack.

[0017] A through hole is arranged in the middle of the support piece, and the rubber hose passes through the through hole and is inserted between the two rotating cylinders.

[0018] As a further improvement, the first driving assembly includes a motor fixedly installed on the side of the base. The output shaft of the motor is inserted on the side of the hose reel cylinder, and the motor is electrically connected to the control module.

[0019] As a further improvement, the second driving assembly includes a first driven gear fixedly mounted on the output shaft, a second driven gear rotatably mounted on the side of the base, and a chain belt connecting the first driven gear and the second driven gear;

[0020] A direction-changing threaded screw inserted and fixed at the center of the second driven gear, the direction-changing threaded screw penetrates through the inside of the guide block and is threadedly connected to the guide block;

[0021] The power is transmitted through the cooperation of the first driven gear and the chain belt to drive the second driven gear to drive the direction-changing threaded screw to rotate, controlling the left and right reciprocating movement of the guide block.

[0022] Wherein, the second driven gear and the motor are arranged on the same side.

[0023] As a further improvement, a guide rod is further included and arranged in parallel below the direction-changing threaded screw, and both ends of the guide rod are fixedly mounted on the base.

[0024] As a further improvement, the inside of the rotating cylinder is set as a hollow structure, and a number of water outlet holes are arranged on the rotating cylinder;

[0025] A water flow input assembly is arranged on one side of the rotating cylinder, and an adaptive blocking assembly is arranged inside the rotating cylinder corresponding to the water outlet holes. When the rotating cylinder rotates slowly, the adaptive blocking assembly blocks the water outlet holes, and when the rotating cylinder rotates quickly, the adaptive blocking assembly releases the water outlet holes, and the water flow input into the rotating cylinder by the water flow input assembly is output through the water outlet holes, and the water flow contacts the surface of the rubber hose.

[0026] As a further improvement, the adaptive blocking assembly includes a cross bar fixedly mounted inside the rotating cylinder away from the water flow input assembly, a number of connecting bars fixedly mounted on the cross bar, and a blocking block fixedly mounted at the end of the connecting bar. The blocking block corresponds to the position of the water outlet hole. In the normal state, the blocking block fits with the water outlet hole.

[0027] As a further improvement, the water flow input assembly includes an outer ring embedded in the adjusting piece, a middle ring welded on the side of the rotating cylinder facing the outer ring, and an inner ring connected to an external water pipe. The outer ring, the middle ring, and the inner ring are arranged in sequence from the outside to the inside. Ball bearings are embedded between the outer ring and the middle ring, and between the middle ring and the inner ring. The rotating cylinder is positioned and fixed by the outer ring, the normal rotation of the rotating cylinder is maintained by the middle ring, and the external water pipe is kept from rotating with the rotating cylinder by the inner ring.

[0028] As a further improvement, it further includes a water pressure detection module arranged inside the inner ring. The water pressure detection module is electrically connected to the control module. Through the cooperation of the water pressure detection module and the control module, the water pressure inside the rotating cylinder is adjusted.

[0029] The beneficial effects of the present invention are as follows:

[0030] In the present invention, by setting a control module, a first driving component and a reel cylinder to cooperate to automatically wind up the rubber hose. Since the wound rubber hose is likely to accumulate in some areas of the reel cylinder, a set of rotating cylinders are designed to clamp and position the rubber hose. Through the cooperation of the second driving component and the guide block, the rotating cylinders are driven to move horizontally left and right during the process of the reel cylinder winding up the rubber hose. Therefore, during the winding process of the rubber hose, the wound rubber hose can be evenly distributed on the reel cylinder.

[0031] However, since a relatively large amount of water is likely to remain inside the rubber hose, the weight of the reel cylinder after winding is relatively heavy. When operations such as handling or replacement are required, it is rather inconvenient. When the rubber hose is wound on the reel cylinder, the internal water flow is discharged by the extrusion of the two rotating cylinders, reducing the retention of water inside the rubber hose and reducing the overall weight.

[0032] Since it is not necessary to completely drain the internal stored water when the rubber hose is not in the replacement state, the distance between the two rotating cylinders is manually and precisely adjusted through the adjustment component, thereby adjusting the extrusion degree on the rubber hose. In the use state, it is necessary to pull the rubber hose outwards. Therefore, the distance between the two rotating cylinders needs to be greater than the diameter of the rubber hose, so as to facilitate the output of the rubber hose and when the rubber hose outputs water, the rubber hose will be fully supported by the internal water flow to provide sufficient space.

[0033] However, when the rubber hose is being wound, the extrusion of the two rotating cylinders on the rubber hose will generate a certain amount of frictional force. At the initial stage of the winding of the reel cylinder, its diameter is relatively small. Therefore, when the reel cylinder rotates one circle, the winding stroke of the rubber hose is limited, resulting in a slower rotation speed of the rotating cylinders. When it comes to the later stage of the winding of the reel cylinder, the accumulated rubber hose increases the overall diameter of the reel cylinder. Therefore, when the reel cylinder rotates one circle, the winding stroke of the rubber hose increases, and the frictional force between the rubber hose and the rotating cylinders increases, which easily pulls the rubber hose and causes deformation. By setting an adaptive sealing component, when the rotation speed of the rotating cylinders increases, under the action of centrifugal force, the connecting strip deforms, causing the end plugging block to leave the position of the water outlet hole, enabling the water outlet hole to communicate with the internal water flow of the rotating cylinder, and leading the internal water flow of the rotating cylinder to be exported through the water outlet hole to contact the rubber hose, thereby reducing the frictional force with the rubber hose.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0044] In the description of the present invention, the terms "first" and "second" are used only for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0045] Referring to Figure 1-7 as shown, a sanitation vehicle with an automatic reel device includes:

[0046] a base 1 fixedly installed on a vehicle body 8, a reel cylinder 2 rotatably installed on the base 1, a first drive assembly for driving the reel cylinder 2 to rotate, and a hose 3 wound around the reel cylinder 2;

[0047] a set of rotating cylinders 4 for clamping and positioning the hose 3 up and down, a guide block 5 for rotatably installing the rotating cylinders 4, and a second drive assembly for driving the guide block 5 to move horizontally left / right. The second drive assembly receives the power of the first drive assembly;

[0048] a control module 6, and the control module 6 is electrically connected to the first drive assembly;

[0049] The rotating cylinder 4 is located on the side of the reel cylinder 2 facing the water outlet end of the hose 3, and the rotating cylinder 4 is arranged parallel to the reel cylinder 2;

[0050] By controlling the first drive assembly to start through the control module 6, driving the reel cylinder 2 to wind up the hose 3 through the first drive assembly, controlling the guide block 5 to reciprocate left and right through the second drive assembly, and driving the hose 3 to adjust the winding position on the reel cylinder 2 from left to right / from right to left through the rotating cylinder 4;

[0051] Among them, the rubber hose 3 discharges the internal water flow through the extrusion of the two rotating cylinders 4.

[0052] Through the cooperation of the control module 6 and the first driving component, the reel cylinder 2 can be automatically started for the winding operation of the rubber hose 3, avoiding the cumbersome manual operation and greatly improving the work efficiency. The user only needs to issue an instruction through the control module 6 to realize the automatic winding and unwinding of the rubber hose 3, reducing the labor intensity of the operator.

[0053] Among them, the second driving component is used to drive the guide block 5 to move horizontally, and the rotating cylinder 4 drives the rubber hose 3 to adjust the winding position left and right, ensuring that the winding positions of the rubber hose 3 on the reel cylinder 2 are evenly distributed. Effectively avoiding problems such as knotting and winding during the winding process of the rubber hose 3, thereby extending the service life of the rubber hose 3 and improving the working stability of the equipment.

[0054] Through the extrusion of the rotating cylinder 4, the water in the rubber hose 3 can be discharged during the winding process, reducing the residual water inside the rubber hose 3 and reducing the weight of the device after winding. In this way, it is not only convenient for handling and replacement, but also avoids the inconvenience of the equipment caused by excessive water and the damage to the rubber hose 3 caused by water accumulation.

[0055] In the present invention, the control module 6, the first driving component and the reel cylinder 2 are arranged to cooperate to automatically wind the rubber hose 3. Since the wound rubber hose 3 is likely to accumulate in some areas of the reel cylinder 2, a set of rotating cylinders 4 are designed to clamp and position the rubber hose 3. Through the cooperation of the second driving component and the guide block 5 to drive the rotating cylinder 4 to move horizontally left and right during the process of winding the rubber hose 3 on the reel cylinder 2, so that during the winding process of the rubber hose 3, the wound rubber hose 3 can be evenly distributed on the reel cylinder 2.

[0056] Compared with the traditional manual or simple mechanical reel devices in the prior art:

[0057] Traditional reel devices usually rely on manual operation, and are prone to problems such as improper operation, winding or unevenness of the rubber hose 3. And this solution reduces the error of manual operation through automatic control, ensuring the efficient and neat winding and unwinding of the rubber hose 3, and greatly improving the operation efficiency and the stability of the equipment.

[0058] In the prior art, many reel devices do not consider the uniformity during the winding process of the rubber hose 3, which is likely to cause the rubber hose 3 to accumulate or knot. Our design ensures the even distribution of the rubber hose 3 on the reel cylinder 2 through the cooperation of the rotating cylinder 4 and the guide block 5, avoiding this problem, thereby extending the service life of the rubber hose 3.

[0059] Traditional devices often neglect the drainage of the moisture inside the rubber hose 3, resulting in excessive water accumulation when the rubber hose 3 is wound up, increasing the weight and affecting the operation. While our solution effectively discharges the moisture inside the rubber hose 3 through the extrusion of the rotating cylinder 4, reduces the moisture residue, lightens the equipment weight, and improves the usability.

[0060] Most of the existing technologies do not have an intelligent control system, resulting in the need for operators to frequently adjust mechanical devices or manually control. While this solution simplifies the operation process through the intelligent management of the control module 6 and can also make precise adjustments according to different situations to ensure that the effect of each winding is in the best state.

[0061] The automated design and intelligent control greatly reduce the labor intensity of the operator, enabling them to complete the tasks of winding and unwinding the rubber hose 3 more easily and efficiently. Compared with traditional devices, the operator does not need to spend a lot of time on manual operations, reducing fatigue and improving the overall operation efficiency.

[0062] Since it is easy for a large amount of water to remain inside the rubber hose 3, the weight of the winding drum 2 after winding is relatively heavy. When operations such as handling or replacement are required, it is rather inconvenient. When the rubber hose 3 is wound on the winding drum 2, the internal water flow is discharged through the extrusion of the two rotating cylinders 4, reducing the retention of the water volume inside the rubber hose 3 and lightening the overall weight.

[0063] Since it is not necessary to completely drain the internal stored water when the rubber hose 3 is in a non-replacement state, the distance between the two rotating cylinders 4 is manually and precisely regulated through the adjusting component, thereby adjusting the extrusion degree on the rubber hose 3. In the usage state, it is necessary to pull the rubber hose 3 outwards. Therefore, the distance between the two rotating cylinders 4 needs to be greater than the diameter of the rubber hose 3, so as to facilitate the output of the rubber hose 3 and when the rubber hose 3 outputs water flow, the rubber hose 3 will be fully supported by the internal water flow to provide sufficient space.

[0064] To precisely adjust the distance between the two rotating cylinders 4, it further includes an adjusting component for driving the two rotating cylinders 4 to move up and down. The adjusting component includes a set of adjusting pieces 7 installed on both sides of the rotating cylinder 4 through a rotating shaft. The adjusting piece 7 is bent outwards to form a first installation part 71, and a bolt 72 is installed on the first installation part 71;

[0065] A vertically arranged supporting piece 73. In the area corresponding to the bolt 72 on the supporting piece 73, a guiding slot hole 74 is vertically arranged. The bolt 72 is inserted into the guiding slot hole 74, and a nut 75 is arranged on the side of the supporting piece 73 away from the bolt 72. The bolt 72 moves up / down in the guiding slot hole 74 through the adjusting piece 7, and is fixed through the cooperation of the bolt 72 and the nut 75 to adjust the distance between the two rotating cylinders 4 corresponding to the diameter of the rubber hose 3.

[0066] As a further improvement, a rack 76 is provided on one side inside the guiding groove. A toothed ring 77 is rotatably sleeved on the bolt 72, and the toothed ring matches the rack 76. A marking 78 is provided on the support piece 73 corresponding to the number of teeth of the rack 76.

[0067] By adding an adjusting component for driving the two rotating cylinders 4 to move up and down, its core function is to adjust the distance between the rotating cylinders 4 to adapt to hoses 3 of different diameters. The adjusting component enables the distance between the two rotating cylinders 4 to be precisely adjusted according to the diameter of the hose 3 through the cooperation of the adjusting piece 7 and the bolt 72.

[0068] Through the cooperation of the bolt 72 and the adjusting piece 7, the distance between the rotating cylinders 4 can be very precisely controlled, ensuring that the hose 3 can be firmly clamped between the rotating cylinders 4, preventing loosening or uneven winding, and prolonging the service life of the hose 3.

[0069] According to hoses 3 of different specifications, the distance between the rotating cylinders 4 can be conveniently adjusted, making the equipment more adaptable and flexible.

[0070] For the specific adjustment method, through the cooperation of the adjusting piece 7 with the bolt 72 and the nut 75 on the support piece 73, the design of the guiding groove hole 74 enables the rotating cylinder 4 to move in the vertical direction (up and down direction). The entire adjustment process is very simple, and the operator only needs to rotate the bolt 72 to complete the precise adjustment of the distance between the rotating cylinders 4, greatly improving the user experience. The benefits include:

[0071] Through the cooperation of the bolt 72 and the nut 75, the adjustment can be completed without the need for complex tools, greatly simplifying the operation process. After the adjustment is completed, through the fixation of the bolt 72 and the nut 75, it can be ensured that the distance between the rotating cylinders 4 will not loosen during the working process, guaranteeing the stability of the operation.

[0072] To improve the adjustment accuracy, the cooperation of the rack 76 and the toothed ring 77 is introduced to achieve more precise control.

[0073] By providing a rack 76 on one side of the guiding groove and installing a toothed ring 77 on the bolt 72, the cooperation of this gear and the rack 76 can make the adjustment process smoother and more precise. The advantages of the combined design of the rack 76 and the toothed ring 77 are:

[0074] The meshing of the rack 76 and the toothed ring 77 can provide a smoother adjustment process, making the movement of the rotating cylinder 4 more uniform and without gaps, avoiding the problem of unsmooth sliding in traditional designs. The presence of the rack 76 helps to reduce the error during the adjustment process and ensures precise control.

[0075] The number of teeth 78 is marked on the rack 76, enabling the operator to visually see the amount of adjustment each time, thereby more precisely controlling the spacing of the rotating drum 4 and further improving the accuracy and controllability of the adjustment.

[0076] Through the design of the cooperation between the adjusting piece 7 and the supporting piece 73, the user can easily adjust the spacing of the rotating drum 4 to adapt to hoses 3 of different diameters. The combination of the guiding groove, the rack 76, and the toothed ring 77 makes the entire adjustment process have higher precision and stronger adaptability. This is a very practical function for an environment with a wide variety of hoses 3 of different diameters.

[0077] During long-term use, the meshing of the rack 76 and the toothed ring 77 provides a more stable long-term adjustment method than the adjustment by the ordinary bolt 72. It can effectively avoid problems such as the loosening, jamming, or unsmooth adjustment of the bolt 72, thus ensuring the reliability of the equipment during long-term use.

[0078] For the adaptability design, by arranging a through hole 79 in the middle of the supporting piece 73, the hose 3 passes through the through hole 79 and is inserted between the two rotating drums 4.

[0079] As a further improvement, the first driving component includes a motor 21 fixedly installed on the side of the base 1, the output shaft of the motor 21 is inserted on the side of the reel cylinder 2, and the motor 21 is electrically connected to the control module 6.

[0080] As a further improvement, the second driving component includes a first driven gear 22 fixedly installed on the output shaft, a second driven gear 23 rotatably installed on the side of the base 1, and a chain belt 24 connecting the first driven gear 22 and the second driven gear 23;

[0081] A reversing threaded screw 25 inserted and fixed at the center of the second driven gear 23, the reversing threaded screw 25 passes through the inside of the guiding block 5 and is threadedly connected to the guiding block 5;

[0082] Through the cooperation of the first driven gear 22 and the chain belt 24 to transmit power, the second driven gear 23 is driven to drive the reversing threaded screw 25 to rotate, controlling the left and right reciprocating movement of the guiding block 5.

[0083] Among them, the second driven gear 23 and the motor 21 are arranged on the same side.

[0084] The first driving component includes a motor 21 and an output shaft. The motor 21 directly drives the reel cylinder 2 through its output shaft. The electric drive of the motor 21 ensures the high efficiency and stability of power transmission. Through the electrical connection of the control module 6, the motor 21 can precisely control the operation of the reel cylinder 2 to achieve precise control and adjustment.

[0085] The motor 21 serves as a power source, providing strong and stable power output, enabling the reel barrel 2 to operate quickly and smoothly, and improving work efficiency.

[0086] The second drive assembly uses a combination of gears and a chain belt 24 to transmit power. From the first driven gear 22 to the second driven gear 23, and then drives the left - right reciprocating motion of the guide block 5 through the reversing threaded screw 25. The combination of the chain belt 24 and the gears can transmit power smoothly, reducing the vibration and noise that may occur during gear meshing. The use of the chain belt 24 ensures efficient power transmission, while reducing system wear and extending the system's lifespan.

[0087] The design of the gears and the chain belt 24 allows the system to achieve power transmission in a smaller space, greatly reducing the volume and making the equipment layout more compact and flexible. The combination of the chain belt 24 and the gears can achieve a high transmission efficiency, ensuring the timely transmission of power and being suitable for scenarios that require precise operation.

[0088] In addition, the combined design of the reversing threaded screw 25 and the guide block 5 enables the equipment to achieve precise left - right reciprocating motion. The reversing threaded screw 25 controls the movement of the guide block 5 by transmitting power. Through the cooperation of the reversing threaded screw 25 and the guide block 5, the movement of the guide block 5 can be effectively controlled to ensure its precise movement in the left - right direction. This is crucial for equipment that requires high precision and ensures the stability of the operation.

[0089] The core of the reversing threaded screw 25 (variable - lead threaded screw) is that through the sudden change or periodic change of the thread geometry, when the screw rotates unidirectionally, it forces the linear motion direction of the guide block 5 (or nut 75) to automatically reverse. Its principle can be divided into two categories:

[0090] Direction - mutation type: The thread helix direction alternates (such as left - hand helix → right - hand helix → left - hand helix), and the motion direction is directly changed by the helix - direction switch.

[0091] Lead - gradual - change type: The thread lead (pitch) changes periodically (such as a sine - wave - shaped lead), and the commutation is indirectly induced by the increase or decrease of the lead.

[0092] (1) Double - lead reversing screw (left - hand helix + right - hand helix alternating):

[0093] The screw is divided into multiple segments, and the helix direction of each segment alternates (for example, left - hand - threaded segment → right - hand - threaded segment → left - hand - threaded segment). The helix - direction junction of each segment is designed for sharp transition or smooth transition (which needs to cooperate with the structure of the guide block 5).

[0094] Motion process: When the screw rotates unidirectionally, the guide block 5 moves along the helix direction of the current thread section. When the guide block 5 reaches the helix intersection point, the helix direction suddenly changes, and the guide block 5 is forced to move in the reverse direction. Transition zone strength: Stress concentration is likely to occur at the helix intersection, and fillets or chamfers are required to reduce stress. Mechanical stoppers are arranged at both ends of the screw to prevent the guide block 5 from detaching from the thread section.

[0095] (2) Wave deformation lead screw (sine wave lead):

[0096] The lead of the screw thread of the screw changes continuously according to a periodic function (such as a sine wave), and the lead formula is:

[0097] P(x)=P0+Asin(2πx / λ);

[0098] where P0 is the average lead, A is the lead amplitude, and λ is the wavelength. The change range of the lead needs to satisfy A < P0 to avoid thread self-locking.

[0099] Motion process:

[0100] When the screw rotates unidirectionally, the moving speed of the guide block 5 increases and decreases periodically due to the change of the lead. When the lead changes to the extreme value (maximum or minimum), the speed of the guide block 5 drops to zero and accelerates in the reverse direction, forming a reciprocating motion.

[0101] In this embodiment, a double-lead reversing screw is adopted. Since the reversing thread screws 25 are all commercially available products, the reversing thread screws 25 of the present application are directly purchased and used, so no further introduction will be made.

[0102] To ensure the stable movement of the guide block 5 and maintain its stable orientation, a guide rod 26 is further included, which is arranged parallel to the lower part of the reversing thread screw 25, and both ends of the guide rod 26 are fixedly installed on the base 1. By cooperating with the guide rod 26 to guide the guide block 5 to move reciprocally left and right, the stable orientation above the guide block 5 can be ensured.

[0103] When the rubber hose 3 is being wound up, the extrusion of the two rotating cylinders 4 on the rubber hose 3 will generate a certain frictional force. At the initial stage of the winding of the reel cylinder 2, its diameter is smaller. Therefore, when the reel cylinder 2 rotates one circle, the winding stroke of the rubber hose 3 is limited, resulting in a slower rotation speed of the rotating cylinder 4. When it comes to the later stage of the winding of the reel cylinder 2, the accumulated rubber hose 3 increases the overall diameter of the reel cylinder 2. Therefore, when the reel cylinder 2 rotates one circle, the winding stroke of the rubber hose 3 increases, and the frictional force between the rubber hose 3 and the rotating cylinder 4 increases, which easily pulls the rubber hose 3 and causes deformation. By setting the adaptive plugging assembly, when the rotation speed of the rotating cylinder 4 increases, under the action of centrifugal force, the connecting strip 44 deforms, causing the plugging block 45 at the end to leave the position of the water outlet hole 42, so that the water outlet hole 42 is communicated with the water flow inside the rotating cylinder 4, and the water flow inside the rotating cylinder 4 is led out through the water outlet hole 42 to contact the rubber hose 3, thereby reducing the frictional force with the rubber hose 3.

[0104] To accurately and precisely control the water flow, the inside of the rotating cylinder 4 is arranged as a hollow structure 41, and a number of water outlet holes 42 are arranged on the rotating cylinder 4;

[0105] A water flow input component is arranged on one side of the rotating cylinder 4, and an adaptive plugging component is arranged inside the rotating cylinder 4 corresponding to the water outlet holes 42. When the rotating cylinder 4 rotates slowly, the adaptive plugging component plugs the water outlet holes 42, and when the rotating cylinder 4 rotates quickly, the adaptive plugging component releases the water outlet holes 42, and the water flow input into the rotating cylinder 4 by the water flow input component is output through the water outlet holes 42, and the water flow contacts the surface of the rubber hose 3.

[0106] As a further improvement, the adaptive plugging component includes a cross bar 43 fixedly installed inside the rotating cylinder 4 away from the water flow input component, a number of connecting bars 44 fixedly installed on the cross bar 43, and a plugging block 45 fixedly installed at the end of the connecting bar 44. The plugging block 45 corresponds to the position of the water outlet holes 42, and in the normal state, the plugging block 45 fits with the water outlet holes 42.

[0107] By arranging a plurality of water outlet holes 42 inside the rotating cylinder 4, the water flow needs to have different control methods at different rotation speeds of the rotating cylinder 4. When the rotating cylinder 4 rotates slowly, the water outlet holes 42 need to be plugged to avoid the water flow flowing out too quickly, so that the water flow can be evenly distributed inside the rotating cylinder 4; and when the rotating cylinder 4 rotates quickly, the water outlet holes 42 are released to allow the water flow to flow out smoothly, ensuring the efficient utilization of the water flow.

[0108] By intelligently controlling the plugging and release of the water outlet holes 42 according to the rotation speed of the rotating cylinder 4, the output volume and flow rate of the water flow can be effectively adjusted, avoiding waste or unnecessary losses caused by excessive water flow.

[0109] Using the adaptive plugging component, especially by controlling the position of the plugging block 45 through the fixed cross bar 43 and connecting bars 44, it can adjust the state of plugging the water outlet holes 42 according to the rotation speed of the rotating cylinder 4. By fitting with the water outlet holes 42, the plugging block 45 can block the water flow in the normal state, ensuring that at an appropriate rotation speed, the water flow can smoothly enter the rotating cylinder 4 and be output through the water outlet holes 42.

[0110] The plugging block 45 can automatically adapt when rotating at low speed and high speed, ensuring the flexibility and efficiency of the system at different rotation speeds. The fitting effect of the plugging block 45 in the normal state can also effectively prevent the water flow from leaking when not needed.

[0111] By controlling the input and output of the water flow, especially by releasing the water outlet holes 42 when the rotating cylinder 4 rotates quickly, it can ensure that the water flow is evenly and timely released. This control strategy can better match the working requirements of the rotating cylinder 4, avoiding problems of excessive or insufficient water flow.

[0112] By intelligently adjusting the blocking state of the water outlet holes 42 in combination with the rotation speed of the rotating drum 4, it is possible to optimize the water flow control at different rotation speeds, ensure the effective utilization of water flow, avoid waste, improve the system efficiency, and enhance the durability and stability of the equipment.

[0113] Among them, the blocking block 45 is made of rubber material, and the connecting strip 44 can be made of a 0.1mm metal sheet with good elasticity or a 1mm rubber strip.

[0114] As a further improvement, the water flow input assembly includes an outer ring 46 embedded and installed on the adjusting piece 7, a middle ring 47 welded to one side of the rotating drum 4 facing the outer ring 46, and an inner ring 48 connected to an external water pipe. The outer ring 46, middle ring 47, and inner ring 48 are arranged in sequence from outside to inside. Ball bearings 49 are installed between the outer ring 46 and the middle ring 47, and between the middle ring 47 and the inner ring 48. The rotating drum 4 is positioned and fixed by the outer ring 46, the normal rotation of the rotating drum 4 is maintained by the middle ring 47, and the external water pipe is kept from rotating with the rotating drum 4 by the inner ring 48.

[0115] It also includes a water pressure detection module 481 arranged inside the inner ring 48. The water pressure detection module 481 is electrically connected to the control module 6. Through the cooperation of the water pressure detection module 481 and the control module 6, the water pressure inside the rotating drum 4 is adjusted.

[0116] The multi-layer structure design of the outer ring 46, middle ring 47, and inner ring 48 realizes precise positioning and rotation control through the ball bearings 49 installed between the rings. The outer ring 46 is used to fix the position of the rotating drum 4, the middle ring 47 is used to ensure the smooth rotation of the rotating drum 4, and the inner ring 48 keeps the external water pipe from rotating with the rotating drum 4.

[0117] Precise positioning is achieved. The outer ring 46 ensures the stable position of the rotating drum 4, avoiding possible offsets or instabilities during the rotation of the rotating drum 4. The cooperation of the middle ring 47 and the ball bearings 49 enables the rotating drum 4 to rotate smoothly, reducing friction and wear, thereby extending the service life of the equipment. The inner ring 48 effectively prevents the water pipe from rotating unnecessarily with the rotating drum 4, ensuring the stable delivery of water flow.

[0118] The design of the inner ring 48 connected to the external water pipe ensures the stable input of water flow. At the same time, the cooperation of the outer ring 46 and the middle ring 47 allows the rotating drum 4 to rotate freely without interfering with the water flow input process. The multi-ring structure of the water flow input assembly optimizes the water flow guiding and input process, can effectively avoid water leakage or instability phenomena, enables the water flow to accurately enter the inside of the rotating drum 4, and improves the flow control accuracy of the entire system.

[0119] By arranging a water pressure detection module 481 inside the inner ring 48 and electrically connecting it to the control module 6, the water pressure state inside the rotating drum 4 is monitored in real time through the water pressure detection module 481, and then the water pressure inside the rotating drum 4 is adjusted.

[0120] When there is more external sediment, the water pressure can be increased to enhance the water flow out. When there is less external sediment, the water pressure can be reduced to decrease the water flow out.
