Description

Technical Field

[0001] The invention belongs to the technical field of water quality monitoring, in particular to a floating device for water quality monitoring. Background Art

[0002] Monitoring water quality refers to the regular or continuous evaluation of the chemical, physical and biological characteristics of water bodies in order to understand the health status, changing trends and whether the water body meets specific water quality standards. Monitoring water quality requires the use of a floating water quality monitoring platform. The floating water quality monitoring platform is an intelligent system that can float on the surface of the water body. It is used to monitor water quality status, changing trends and environmental health. Water quality indicators need to be tested before the water source is used. When testing water quality indicators, the detection head needs to be placed in the water.

[0003] After searching, the application with patent publication number CN221485384U provides a water quality detection device for aquaculture, including a floating component, and also including: a detection mechanism capable of performing water quality detection on water areas of different depths, and the detection mechanism is installed on the floating component, the floating component includes: foam for floating on the water surface, the supporting plate is fixedly installed on the side of the foam away from the water surface, the detection mechanism includes: a sampling component, and the sampling component is installed on the supporting plate. By setting up the detection mechanism, it has the function of being able to detect water quality on water areas of different depths. By performing water quality detection on water areas of different depths, it can solve the problem that the water depth detected by the current water quality detection device is usually fixed when detecting water for aquaculture, thereby improving the detection accuracy of water for aquaculture.

[0004] When the above device is in use, although it can extract water of different depths for testing, it can only perform extraction testing once.

In addition, the bottom of the hose is simply provided with a filter cover. After long-term use, it is easy to cause debris to adhere to the surface of the filter cover or algae to grow, thereby affecting the normal water pumping of the hose.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention, through the coordinated arrangement of the floating seat, the fixed seat, the winding disk, the sampling mechanism, the transmission mechanism, the water delivery mechanism and the detection mechanism, can utilize the operation of the double-axis motor to make the left output end drive the first spur gear to rotate, and then make the second spur gear drive the delivery pipe to rotate between the two rotating joints, and drive the winding disk to rotate together, so that the hose is released in the winding disk, and the descent depth of the stainless steel filter cartridge in the water area can be adjusted. At the same time, the right output end of the double-axis motor will drive the screw to rotate through the belt, and then control the support to drive the water collection frame to move, so that the partition can collect water of different depths respectively. After the water of high temperature drops to the specified position, the solenoid valve at the water pumping end is opened, and the solenoid valve on the recoil pipe is closed. Then the water is extracted by the operation of the water pump. During the extraction process, the water will flow into the fixed pipe, the hose and the delivery pipe in turn, and finally the extracted water will be discharged into the water collecting frame through the water delivery pipe for temporary storage. Then the water quality detection line head is used to detect the water at different positions in the water collecting frame, and the detected data is transmitted and monitored through the signal transmitter.

[0017] The present invention is provided with a first cleaning mechanism and a recoil mechanism. When the hose is rolled up, the fixed tube drives the stainless steel filter cartridge to move upward until the top of the stainless steel filter cartridge is located on the bottom surface of the floating seat. The stainless steel filter cartridge is automatically positioned, and the first bevel gear is automatically meshed with the second bevel gear, and the second convex rod is also meshed with the cone block. Subsequently, the second bevel gear is driven by a driving motor to rotate, so that the second bevel gear drives the first bevel gear to rotate, thereby realizing the rotation of the stainless steel filter cartridge, so that the stainless steel filter cartridge rotates on the surface of the fixed tube. At the same time, the second convex rod also moves the cone block, thereby rotating the third spur gear. The rotation of the third spur gear drives the fourth spur gear to rotate, thereby realizing the same-direction rotation of the stainless steel filter cartridge and the cleaning brush, and the rotation speed of the cleaning brush is greater than the rotation speed of the stainless steel filter cartridge, thereby effectively removing the debris on the surface of the stainless steel filter cartridge. At the same time, the water in the water collecting frame is drained into the slot, the solenoid valve at the water pumping end is closed, and then the inside of the recoil pipe is blown by the operation of the air pump, so that the water in the recoil pipe can flow into the delivery pipe, the hose and the fixed pipe in turn, and finally be discharged from the through hole on the surface of the U-shaped pipe, so as to backwash the stainless steel filter cartridge, thereby ensuring the cleanliness of the stainless steel filter cartridge.

[0018] The present invention arranges a second cleaning machine. When the stainless steel filter cartridge descends in the water area, the rotation of the winding disk will cause the left and right groups of first protruding rods to press the two upper inclined plates downward, so that the two upper inclined plates respectively drive the two fixed frames to move downward, and then the two lower inclined plates are respectively squeezed and moved on the top ends of the two push rods, so that the two cleaning cottons are moved away from each other and the contact with the fixed pipe is released to ensure the normal descent of the stainless steel filter cartridge. Only when the hose is rolled up in the winding disk, the two groups of first protruding rods respectively push the two upper inclined plates, so that the two upper inclined plates are squeezed into the corresponding installation grooves, so that the two cleaning cottons can clean and wipe the hose during the rolling process, thereby ensuring the cleanliness of the hose after rolling up.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 12 As shown, the present invention provides a floating device for water quality monitoring, including a floating seat 1, two fixed seats 6 are fixedly connected to the floating seat 1, a winding disk 5 is rotatably arranged between the two fixed seats 6, a sampling mechanism is arranged in the middle of the winding disk 5, a transmission mechanism for driving the sampling mechanism to rotate is arranged on one of the fixed seats 6, a water supply mechanism and a recoil mechanism are respectively arranged on the sides of the two fixed seats 6 away from each other, a detection mechanism is arranged behind the winding disk 5, the detection mechanism is located above the water supply mechanism, the water supply mechanism and the recoil mechanism are connected, and a first cleaning mechanism and a second cleaning mechanism for cleaning the sampling mechanism are arranged in front of the winding disk 5. The machinery, parts and equipment in this device all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0023] By adopting the above scheme: the transmission mechanism can be used to drive the sampling mechanism and the winding disk 5 to rotate between the two fixed seats 6, so that the sampling mechanism can be lowered to different depths of the water area, and then the water supply mechanism is used to extract and transport water at different depths in turn, and temporarily store it. During this period, the detection mechanism can be used to detect the water quality of water at different extraction depths, so as to monitor the water in the water area. After completing the detection of water at different depths, the transmission mechanism can be used to control the sampling mechanism to rise, and then the water temporarily stored in the water supply mechanism is discharged into the recoil mechanism, and finally the recoil mechanism is used to discharge the temporarily stored water through the sampling mechanism. Not only can the temporarily stored water be discharged, but the discharged water can also flush the sampling mechanism, effectively preventing the bottom of the sampling mechanism from adhering to debris or growing algae, thereby ensuring that the sampling mechanism can sample the water area smoothly, without the need for additional water extraction, and the first cleaning mechanism and the second cleaning mechanism can be used to clean the sampling mechanism more comprehensively, ensuring the cleanliness of the device under long-term use.

[0024] It is worth noting here that when the sampling mechanism extracts and transports water in the water area, the water can only be transported through the water delivery mechanism and will not flow into the recoil mechanism. When the recoil mechanism discharges the tested water through the sampling mechanism, it will not flow into the water delivery mechanism, and the recoil mechanism is used in conjunction with the first cleaning mechanism.

[0025] like Figures 3 to 6 As shown, the sampling mechanism includes a delivery pipe 22 and two rotary joints 23. The two rotary joints 23 are respectively fixedly connected to the two fixed seats 6 so that the rotary joints 23 will not move on the fixed seats 6. The two ends of the delivery pipe 22 are respectively rotatably connected to the rotating ends of the two rotary joints 23. The middle part of the winding disk 5 is fixedly connected to the middle part of the delivery pipe 22. A hose 45 is wound around the winding disk 5. One end of the hose 45 is connected to the middle part of the winding disk 5. The other end of the hose 45 is connected to the fixed pipe 24. The bottom end of the fixed pipe 24 passes through the floating seat 1 and is movably connected to the stainless steel filter cartridge 3. A U-shaped pipe 28 is arranged in the stainless steel filter cartridge 3, and the middle part of the U-shaped pipe 28 is connected to the floating seat 1. The bottom ends of the fixed tubes 24 are connected, and a plurality of through holes are provided on the surface of the U-shaped tube 28. The top end of the stainless steel filter cartridge 3 is rotatably connected to the surface of the fixed tube 24. The fixed tube 24 will not be deformed, and the fixed tube 24 is a stainless steel tube. A positioning ring is provided at the top end of the stainless steel filter cartridge 3, and a positioning groove matching the positioning ring is provided on the bottom surface of the floating seat 1, and a ball positioning groove and a ball are embedded in the positioning groove (not shown in the figure). When the stainless steel filter cartridge 3 rises to the bottom surface of the floating seat 1, the positioning ring at the top end of the stainless steel filter cartridge 3 will be inserted into the positioning groove, which is beneficial to positioning the stainless steel filter cartridge 3, making the stainless steel filter cartridge 3 more stable during subsequent rotation to prevent it from shaking at will.

[0026] The above scheme is adopted: when the conveying pipe 22 rotates, it also drives the winding disk 5 to rotate, so that the hose 45 descends to different depths in the water area, and then the stainless steel filter cartridge 3 can be used to filter the water extracted by the U-shaped tube 28, so as to prevent the impurities in the water area from clogging the U-shaped tube 28, thereby ensuring the accuracy of water detection in the water area, so that the U-shaped tube 28 can not only pump water but also drain water. In the process of drainage, the through holes on the surface of the U-shaped tube 28 can also be used to rinse the surface of the stainless steel filter cartridge 3, so as to wash away the impurities on the surface of the stainless steel filter cartridge 3.

[0027] like Figures 3 to 5 As shown, the transmission mechanism includes a dual-axis motor 12, which is mounted on a fixed seat 6, a second spur gear 11 is fixedly connected to the surface of a delivery pipe 22, a first spur gear 21 is fixedly connected to the left output end of the dual-axis motor 12, and the first spur gear 21 is meshed with the second spur gear 11.

[0028] By adopting the above scheme, the first spur gear 21 can drive the second spur gear 11 to rotate by the operation of the dual-axis motor 12, thereby causing the conveying pipe 22 to rotate between the two rotary joints 23, and driving the winding disk 5 to rotate together, thereby controlling the retraction and extension of the hose 45, and thereby adjusting the lifting and lowering of the stainless steel filter cartridge 3.

[0029] like Figures 3 to 5 As shown, the water supply mechanism includes a water pump 18 and a water supply pipe 8. The water pump 18 is installed on the side of the fixed seat 6. The water pumping end of the water pump 18 is connected to the rotating joint 23, and the water pumping end of the water pump 18 is installed with an electromagnetic valve. The water supply pipe 8 is connected to the water supply end of the water pump 18. A water collecting frame 9 is arranged behind the winding drum 5, and the drainage outlet of the water supply pipe 8 is located on the water collecting frame 9.

[0030] The above scheme is adopted: when the stainless steel filter cartridge 3 descends to the specified depth of the water area, water can be extracted by operating the water pump 18. During the extraction process, the water will flow into the fixed pipe 24, the hose 45 and the delivery pipe 22 in sequence, and finally the extracted water will be discharged into the water collection frame 9 through the water delivery pipe 8 for temporary storage, so as to facilitate the subsequent detection of the water in the water collection frame 9 using a detection mechanism.

[0031] like Figure 3 , Figure 4 , Figure 8 and Fig. 9As shown, the inner wall of the water collecting frame 9 is fixedly connected with a plurality of partitions 14, the bottom surface of the water collecting frame 9 is fixedly connected with a pillar 17, and two fixed plates 15 are fixedly connected to the floating seat 1, and a screw 16 and two positioning rods are rotatably connected between the two fixed plates 15, the bottom end of the pillar 17 is threadedly sleeved on the screw 16, and the pillar 17 is sleeved on the two positioning rods, the right end of the screw 16 and the right output end of the dual-axis motor 12 are fixedly connected with a transmission wheel, and the two transmission wheels are connected by belt drive, and the bottom surface of the water collecting frame 9 is connected with a plurality of drain pipes 39, and each drain pipe 39 is installed with a solenoid valve.

[0032] The above scheme is adopted: when the dual-axis motor 12 drives the stainless steel filter cartridge 3 to descend, the right output end of the dual-axis motor 12 will drive the screw 16 to rotate through the belt, and then control the support 17 to drive the water collecting frame 9 to move, so that the partition 14 can collect water of different depths respectively, and the stainless steel filter cartridge 3 will also drive the water collecting frame 9 to move while rising and falling, without the need for repeated pumping. When the water in the water collecting frame 9 is tested, the solenoid valve on each drain pipe 39 is controlled to open, and the water in the water collecting frame 9 can be discharged into the recoil mechanism.

[0033] like Figures 3 to 5 As shown, the recoil mechanism includes an air pump 19 and a recoil pipe 7. The air pump 19 is installed on the side of the fixed seat 6. One end of the recoil pipe 7 is fixedly connected to the rotary joint 23 on the left and is equipped with a solenoid valve. A slot 13 is provided on the recoil pipe 7. The bottom end of each drain pipe 39 slides in the slot 13. The output end of the air pump 19 is connected to the recoil pipe 7.

[0034] By adopting the above scheme, the water in the water collecting frame 9 can be discharged into the groove 13. At the same time, the solenoid valve at the water pumping end of the water pump 18 is closed, and then the inside of the recoil tube 7 is blown by the operation of the air pump 19, so that the water in the recoil tube 7 can flow into the delivery pipe 22, the hose 45 and the fixed pipe 24 in turn, and finally discharged from the through hole on the surface of the U-shaped tube 28.

[0035] like Figure 1 to Figure 2As shown, the detection mechanism includes a water quality detector 10, a side plate 46 and a water quality detection line head 25. The water quality detector 10 is fixedly connected to the floating seat 1, and the water quality detector 10 is located behind the water collecting frame 9. The water quality detector 10 is connected with a signal transmitter and a controller. The controller is used to control various electrical components on the floating seat 1, and various electrical components on the floating seat 1 are electrically connected to the controller. The water quality detector 10, the water quality detection line head 25, the signal transmitter and the controller are all well known to those skilled in the art, and belong to conventional means or common knowledge. In addition, the detection value transmitted by the water quality detector 10 is received by the controller and sent to the detection personnel terminal through the signal transmitter. It is a basic wireless transmission method well known to those skilled in the art, which belongs to conventional means or common knowledge and will not be repeated here. 6 is fixedly connected to the water quality detector 10, and the side plate 46 is located above the water quality detection line head 25, the water quality detection line head 25 is fixedly connected to the floating seat 1, and a movable plate 49 is fixedly connected to the middle of the water quality detection line head 25. The water quality detection line head 25 has the characteristic of deformation, so the water quality detection line head 25 can be bent, and a fixed cylinder 43 is fixedly connected to the bottom surface of the movable plate 49, and the fixed cylinder 43 is sleeved on the surface of the water quality detection line head 25. Two opposite guide rods 47 are fixedly connected to the movable plate 49, and the top of the guide rod 47 passes through the top of the side plate 46. The surface of each guide rod 47 is wrapped with a second compression spring 48, and the two ends of the second compression spring 48 are respectively fixedly connected to the surfaces of the side plate 46 and the movable plate 49. The bottom end of the fixed cylinder 43 is rotatably connected to two opposite rollers 50, and the rollers 50 slide on the V-shaped plate 38.

[0036] The above scheme is adopted: when the water quality detection thread head 25 detects water at different positions in the water collecting frame 9, the water collecting frame 9 is rotated and moved on the screw 16 through the support 17, so that the V-shaped plate 38 can automatically push the roller 50 to move upward, and then the bottom end of the water quality detection thread head 25 is automatically located at other positions of the water collecting frame 9. When the roller 50 is in the middle of the V-shaped plate 38, the bottom end of the water quality detection thread head 25 will contact the water in the water collecting frame 9, and the water quality will be further detected, thereby improving the water quality detection efficiency of water at different depths and improving the practicability of the device.

[0037] like Figure 3 , Fig.10 and Fig.11As shown, the first cleaning mechanism includes a driving motor 44, the output end of the driving motor 44 is fixedly connected to the second bevel gear 41, and the bottom end of the second bevel gear 41 passes through the bottom of the floating seat 1, the top of the stainless steel filter cartridge 3 is fixedly connected to the first bevel gear 26 adapted to the second bevel gear 41, the bottom surface of the floating seat 1 is rotatably connected to the third spur gear 40 and the fourth spur gear 42, and the third spur gear 40 and the fourth spur gear 42 are meshed, the top of the stainless steel filter cartridge 3 is fixedly connected to the second convex rod 27 of the circumferential array, the bottom surface of the third spur gear 40 is fixedly connected to the cone block 51 of the circumferential array, and the second convex rod 27 is meshed with the cone block 51, the bottom surface of the fourth spur gear 42 is fixedly connected to the cleaning brush 4, and the cleaning brush 4 is in contact with the surface of the stainless steel filter cartridge 3.

[0038] The above scheme is adopted: when the hose 45 is rolled up, the fixed tube 24 drives the stainless steel filter cartridge 3 to move upward until the top end of the stainless steel filter cartridge 3 is located on the bottom surface of the floating seat 1, the stainless steel filter cartridge 3 is automatically positioned, and the first bevel gear 26 is also automatically meshed with the second bevel gear 41. Since the tooth ends of the first bevel gear 26 and the second bevel gear 41 are both pointed, the first bevel gear 26 and the second bevel gear 41 can be easily meshed, and the second protruding rod 27 is also meshed with the cone block 51. Since the bottom end of the cone block 51 is pointed, the second protruding rod 27 will not be squeezed and broken, and the cleaning brush 4 is set with soft bristles, so that the cleaning brush 4 will not hinder the rise of the stainless steel filter cartridge 3. Subsequently, the driving motor 44 is utilized to drive the second bevel gear 41 to rotate, so that the second bevel gear 41 drives the first bevel gear 26 to rotate, thereby realizing the rotation of the stainless steel filter cartridge 3, and causing the stainless steel filter cartridge 3 to rotate on the surface of the fixed tube 24. At the same time, the second protruding rod 27 also moves the cone block 51, thereby causing the third spur gear 40 to rotate. The rotation of the third spur gear 40 drives the fourth spur gear 42 to rotate, thereby realizing the same-direction rotation of the stainless steel filter cartridge 3 and the cleaning brush 4, and the rotation speed of the cleaning brush 4 is greater than the rotation speed of the stainless steel filter cartridge 3, so that the debris on the surface of the stainless steel filter cartridge 3 can be effectively removed. When the stainless steel filter cartridge 3 is cleaned, the driving motor 44 can be stopped.

[0039] like Figure 3 , Figure 5 , Figure 7 and Fig.11As shown, the second cleaning mechanism includes two fixed frames 29 and two push rods 37, the two push rods 37 are fixedly connected to the floating seat 1, the left and right sides of the winding disk 5 are fixedly connected with the first convex rods 20 of the circumferential array, the bottom ends of the two fixed frames 29 are fixedly connected with the first compression spring 36, and the bottom ends of the first compression spring 36 are fixedly connected to the floating seat 1, and the adjacent side surfaces of the two fixed frames 29 are provided with two mounting grooves 32, and each mounting groove 32 is slidably provided with an inclined plate 31 and a spring 30 fixedly connected, and the spring 30 One end is connected to the inclined plate 31, the top ends of the two push rods 37 are respectively in contact with the bottom surfaces of the two inclined plates 31 located below, the top ends of the two inclined plates 31 located below are fixedly connected with cleaning cotton 33, and the two cleaning cotton 33 are sleeved on the surface of the fixed tube 24, the two inclined plates 31 located above are respectively in contact with the left and right groups of first protruding rods 20, the two push rods 37 are provided with sliding grooves 34, the bottom ends of the two fixed frames 29 are fixedly connected with sliding blocks 35, and the sliding blocks 35 slide in the sliding grooves 34.

[0040] The above scheme is adopted: when the stainless steel filter cartridge 3 descends in the water area, the rotation of the winding disk 5 will cause the left and right groups of first protruding rods 20 to squeeze the two upper inclined plates 31 downward, so that the two upper inclined plates 31 respectively drive the two fixed frames 29 to move downward, and then the two lower inclined plates 31 are squeezed and moved at the top ends of the two push rods 37 respectively, so that the two cleaning cottons 33 are moved away from each other and the contact with the fixed tube 24 is released to ensure the normal descent of the stainless steel filter cartridge 3. Only when the hose 45 is wound in the winding disk 5, the two groups of first protruding rods 20 respectively push the two upper inclined plates 31, so that the two upper inclined plates 31 are squeezed into the corresponding mounting grooves 32, so that the two cleaning cottons 33 can clean and wipe the hose 45 during the winding process, thereby ensuring the cleanliness of the hose 45 after winding.

[0041] like Figure 1 to Figure 2 As shown, a protective cover 2 is provided on the floating seat 1, and the protective cover 2 is detachably connected to the floating seat 1.

[0042] With the above solution, the components on the floating seat 1 can be protected by the protective cover 2, and the bottom of the protective cover 2 is connected to the floating seat 1 by bolts, so that subsequent personnel can remove the protective cover 2 and replace and maintain the components on the floating seat 1.

[0043] The working principle and use process of the present invention are as follows: first, the floating seat 1 is placed in the water area, and when the water quality of the water area is monitored, the left output end is used to drive the first spur gear 21 to rotate under the operation of the double-axis motor 12, and then the second spur gear 11 drives the conveying pipe 22 to rotate between the two rotating joints 23, and drives the winding disk 5 to rotate together, so that the hose 45 is released in the winding disk 5, and the descent depth of the stainless steel filter cartridge 3 in the water area can be adjusted. At the same time, the right output end of the double-axis motor 12 will drive the screw 16 to rotate through the belt, and then control the support 17 to drive the water collection frame 9 to move, so that the partition 14 can collect water of different depths respectively. After descending to the specified position, the solenoid valve at the water pumping end of the water pump 18 is opened. , and close the solenoid valve on the recoil pipe 7, and then use the water pump 18 to extract water. During the extraction process, the water will flow into the fixed pipe 24, the hose 45 and the delivery pipe 22 in turn, and finally the extracted water will be discharged into the water collecting frame 9 through the water delivery pipe 8 for temporary storage, and then the water quality detection line head 25 is used to detect the water at different positions in the water collecting frame 9, and the detected data is transmitted and monitored through the signal transmitter, and the water quality detection line head 25 can detect the water at different positions in the water collecting frame 9 when the dual-axis motor 12 is running, which improves the practicality of the device. After completing the water quality detection, the reel 5 reels the hose 45 until the top of the stainless steel filter cartridge 3 is at the bottom of the floating seat 1 and automatically The stainless steel filter cartridge 3 is positioned, and the first bevel gear 26 is automatically meshed with the second bevel gear 41, and the second protruding rod 27 is also meshed with the cone block 51, and then the driving motor 44 is used to drive the second bevel gear 41 to rotate, so that the second bevel gear 41 drives the first bevel gear 26 to rotate, thereby realizing the rotation of the stainless steel filter cartridge 3, and the rotation of the stainless steel filter cartridge 3 will drive the third spur gear 40 to rotate, and the rotation of the third spur gear 40 will drive the fourth spur gear 42 to rotate, so that the cleaning brush 4 cleans the surface of the stainless steel filter cartridge 3. At the same time, when the water in the water collecting frame 9 is detected, the solenoid valve on each drain pipe 39 is controlled to open, so that the water in the water collecting frame 9 can be discharged into the recoil mechanism, and the water in the water collecting frame 9 can be discharged into the recoil mechanism. The water in the recoil pipe 7 can be discharged into the slot 13. At the same time, the solenoid valve at the water pump end of the water pump 18 is closed, and then the inside of the recoil pipe 7 is blown by the operation of the air pump 19, so that the water in the recoil pipe 7 can flow into the delivery pipe 22, the hose 45 and the fixed pipe 24 in sequence, and finally discharged from the through hole on the surface of the U-shaped tube 28, and the surface of the stainless steel filter cartridge 3 is recoiled, thereby improving the cleaning effect of the stainless steel filter cartridge 3. When the hose 45 is wound in the winding drum 5, the two groups of first protrusions 20 respectively push the two upper inclined plates 31, so that the two upper inclined plates 31 are squeezed into the corresponding mounting grooves 32, so that the two cleaning cottons 33 can clean and wipe the hose 45 during the winding process, thereby ensuring the cleanliness of the hose 45 after winding.
