Description

Technical Field

[0001] This invention relates to the field of pipeline cleaning technology, specifically to a pipeline measurement and cleaning device and its construction method. Background Technology

[0002] The inspection wells of drainage pipes with high water levels contain a large amount of silt and suspended, floating, and settled debris, which greatly hinders operations such as airbag sealing, robotic inspection, dredging, and sludge removal. Typically, divers descend into the well, using their extended arm (height) and experience to judge the diameter of the drainage pipe and the water level depth. They then use their arms to grab the tangled debris and carry it to the vertical well opening. Because the drainage pipe environment is complex, with zero visibility and filled with toxic, flammable, and explosive gases, it poses a significant risk of personal injury or death.

[0003] Currently, there are some pipe cleaning machines on the market, but most of them have complex structures and only have cleaning functions, making it difficult to achieve accurate pipe measurement. For example, the existing patent technology with patent publication number CN219541254U, entitled "A Pipeline Silt Cleaning Device for Water Conservancy Projects," describes a sludge cleaning device for pipelines, which specifically includes "a frame; an adjustment mechanism is occasionally provided on the outer surface of the frame, the adjustment mechanism supports a wheel assembly and outputs a linear degree of freedom, adjusting the wheel assembly to fit against the inner wall of the pipe; the wheel assembly drives the frame to move; and a sludge cleaning component for pipe cleaning is provided at the front of the frame." Although the above patent can achieve pipe cleaning, it is only suitable for horizontal pipes or wells and is not suitable for vertical pipes or vertical wells, thus having a narrow range of applications. At the same time, the device can only disperse sludge to unclog the pipe, but it cannot grab and remove suspended, floating, settled, or entangled materials from the pipe, thus having certain limitations. Furthermore, the above patent cannot simultaneously measure the pipe diameter. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to solve the current problems of measuring underwater well depth and pipe diameter and cleaning up entangled materials in pipelines in an integrated manner.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A pipe measuring and cleaning device includes a connecting rod assembly, a probe assembly, an upper drive flexible shaft, a hand drill, a lower drive flexible shaft, and a dredging auger assembly;

[0007] The bottom of the connecting rod assembly is detachably connected to the probe assembly and can form a pipe measuring component;

[0008] Alternatively, the bottom of the connecting rod assembly can be detachably connected to the dredging head assembly via a lower drive flexible shaft to form a pipe cleaning component, and the top of the connecting rod assembly can be detachably connected to an electric drill via an upper drive flexible shaft, wherein the electric drill can drive the dredging head assembly to rotate.

[0009] This application enables pipe cleaning by setting up a connecting rod assembly, with the top of the assembly connected to an electric drill via an upper drive flexible shaft, and the bottom of the assembly connected to a dredging auger assembly. Removing the dredging auger assembly and replacing it with a probe assembly enables pipe measurement. This application is flexible and adaptable to both vertical and horizontal wells, expanding its application range. Simultaneously, it can measure underwater well depth and pipe diameter, as well as remove entangled debris. Compared to traditional methods of frogman diving into wells, this significantly improves work efficiency. Furthermore, this application offers high exploration safety and is simple and easy to operate.

[0010] As a further aspect of the present invention: the connecting rod assembly consists of several connecting rod sleeves connected end to end that are detachably connected, wherein a connecting sleeve assembly is also tightly fitted on the outer side of two adjacent connecting rod sleeves.

[0011] As a further aspect of the present invention: the inside of the connecting rod sleeve is provided with a transmission spindle, one end of the transmission spindle is connected to an upper clamp, wherein the outer side of the upper clamp is connected to the inner side of the connecting rod sleeve through a bearing assembly;

[0012] The other end of the transmission spindle is connected to a lower clamp corresponding to the upper clamp, wherein the outer side of the lower clamp is also connected to the inner side of the connecting rod sleeve through a bearing assembly.

[0013] As a further aspect of the present invention: the bearing assembly includes a bearing 1 disposed on the outside of the upper or lower clamping member, the outside of the bearing 1 being connected to the inside of the connecting rod sleeve through a bearing seat, wherein an inner retaining spring is disposed above the bearing 1, and the other end of the inner retaining spring is inserted into the bearing seat.

[0014] As a further aspect of the present invention: the probe assembly includes a pointed insert rod, a horizontal well probe, and a fixing screw, wherein the top of the pointed insert rod can be connected to the connecting rod assembly through a connecting sleeve assembly, and the horizontal well probe is installed at a slightly upper position on the pointed insert rod in the horizontal direction.

[0015] As a further aspect of the present invention: the upper transmission flexible shaft and the lower transmission flexible shaft have the same structure, wherein one end of the upper transmission flexible shaft is provided with a first connecting end, and the other end of the upper transmission flexible shaft is provided with a second connecting end corresponding to the first connecting end.

[0016] As a further aspect of the present invention: the dredging auger assembly includes a guide frame and auger blades located at one end of the guide frame;

[0017] A guide fixing sleeve is installed at the center of the guide frame, and a flexible shaft sleeve is provided on the inner side of the guide fixing sleeve. The interior of the flexible shaft sleeve is connected to the end of the lower drive flexible shaft.

[0018] The outer side of the flexible shaft sleeve, located on one side of the guide fixing sleeve, is also connected to a swivel blade via a bearing. The end of the flexible shaft sleeve is provided with a receiving plate that connects to the lower drive flexible shaft.

[0019] The present invention also discloses a measurement method for a pipeline measurement and cleaning device, comprising the following steps:

[0020] A1. The probe assembly is installed on the lower part of the connecting rod assembly through the connecting sleeve assembly to form a pipeline measuring component. The length and number of connecting rods can be selected according to the well depth, and they are connected together through the connecting sleeve.

[0021] A2. Then, a person stands at the vertical wellhead and inserts the probe vertically into the well, forcefully inserting it at several points until it passes through the silt at the bottom of the well and enters the horizontal well channel.

[0022] A3. Then find the deepest point and mark it on the ground plane with the corresponding mark A1 on the outer sleeve of the connecting rod. At this time, the vertical well depth H = H1 + A1.

[0023] A4. When the probe assembly approaches the vertical well wall, the horizontal wellhead is located by rotating the horizontal well probe. The top of the horizontal wellhead can block the horizontal well probe. At this time, the riser diameter of the probe assembly is H2.

[0024] A5. Then, pull the probe assembly at the location of the horizontal well and scrape the upper wall of the horizontal well through the horizontal well probe. At this time, mark the corresponding scale A2 between the ground plane and the outer sleeve of the connecting rod. The diameter of the horizontal well can then be obtained by calculation.

[0025] A6. Finally, develop a pipeline cleaning plan based on the dimensions measured in the vertical and horizontal shafts.

[0026] As a further aspect of the present invention: in step A5, the diameter of the horizontal well DN = H1 + H2, and the diameter of the probe assembly riser pipe H2 = A1 - A2.

[0027] The present invention also discloses a cleaning method for a pipeline measuring and cleaning device, comprising the following steps:

[0028] B1. The upper drive flexible shaft is installed on the upper part of the connecting rod assembly and the lower drive flexible shaft is installed on the lower part of the connecting rod assembly through the connecting sleeve assembly. The electric drill is connected to the upper drive flexible shaft and the dredging auger assembly is connected to the lower drive flexible shaft.

[0029] B2. Then, two people need to operate around the wellhead. One person holds the connecting rod assembly and slowly lowers the dredging auger assembly and the lower transmission hose below the vertical water surface of the well. The other person holds the electric drill and controls its operation.

[0030] B3. Then the electric drill starts working and starts rotating. It drives the auger blades to rotate through the upper drive flexible shaft, the connecting rod assembly, and the drive spindle in the lower drive flexible shaft. It stirs up and wraps the floating, suspended, and sunken linear, flaky, and flocculent debris in the water around the auger blades, and lifts the auger blades upward to complete the cleaning of the entangled debris in the vertical well.

[0031] B4. After the vertical shaft is cleaned, place the connecting rod assembly and the sludge auger assembly close to the horizontal shaft opening. Slowly press down and pull the connecting rod assembly in the opposite direction of the horizontal shaft opening to bend and deform the lower transmission flexible shaft, pushing the sludge auger guide frame to move towards the horizontal shaft. During the rotation of the auger blades and their entry into the horizontal shaft, linear, flaky, and flocculent debris in the horizontal shaft will be wrapped around the rotating auger. Remove the rotating auger to complete the cleaning of the entangled material.

[0032] B5. The operator can increase or decrease the number of connecting rods at any time according to the well depth, and move the connecting rods back and forth, up and down, and around the perimeter to achieve blind-spot-free cleaning of the rotating winch head.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] I. This application achieves pipe cleaning by setting up a connecting rod assembly, which is connected to an electric drill via an upper transmission flexible shaft at the top and a dredging auger assembly at the bottom. Pipe measurement can be achieved by removing the dredging auger assembly and replacing it with a probe assembly. This application can be flexibly adapted to vertical and horizontal wells, thus expanding its application range. At the same time, this application can simultaneously measure underwater well depth and pipe diameter as well as remove entangled objects. Compared with the traditional method of frogmen diving into wells, this greatly improves work efficiency. Furthermore, this application has high exploration safety and is simple and easy to operate.

[0035] 2. The extension pole assembly of this application is composed of several extension pole outer sleeves spliced ​​together, and adjacent extension pole outer sleeves are reinforced by connecting sleeve assemblies. This design allows the extension pole assembly to be quickly assembled and disassembled, its length to be adjusted at will, it to be easy to carry, and it has a wide measurement range.

[0036] Third, this application uses a probe assembly installed at the bottom of the connecting rod assembly to measure the pipeline. The probe assembly includes a pointed insertion rod and a horizontal well probe. The pointed insertion rod has strong penetrating power and can easily penetrate debris and insert into the bottom of the well. It is used in conjunction with the scale of the connecting rod to measure the well depth, making the measurement simple and accurate. The horizontal well probe is lifted to measure the diameter of the horizontal well. The diameter of the horizontal well can be found by marking the position and simple calculation. Compared with the measurement by frogman's arm in the well and the exploration by robot equipped with sonar, this application is safer and more simple to operate.

[0037] Fourth, the auger blades of this application have multiple arched structures, and this arrangement enables the auger blades to have a strong ability to grip and clean tangled objects during high-speed rotation.

[0038] 5. The guide frame of this application is located on the rear side of the auger blade, and the guide frame is also a multi-arched structure. The outer edge dimension of the guide frame is larger than the outer edge dimension of the auger blade. This design can prevent the auger blade from touching the pipe wall or the bottom of the pipe and causing it to be unable to rotate or even damage the parts.

[0039] VI. This application connects an upper drive flexible shaft and a lower drive flexible shaft to the upper and lower ends of the connecting rod assembly, respectively. The two have the same structure, but the drive flexible shaft has good toughness and good guiding properties. Through bending deformation under force, it can easily enter and exit the horizontal shaft in conjunction with the arched guide frame and the auger blade.

[0040] VII. This application can adapt to well depth by deforming the upper transmission flexible shaft and changing the number of connecting rods. The operator's position for the handheld electric drill can be fixed and is not limited by well depth or connecting rod height. It can meet the needs of cleaning up debris and entangled waste in vertical and horizontal wells of different depths.

[0041] 8. Depending on the mass, shape, and spatial position of the entangled material inside the pipeline, this application may select to install components such as inflatable airbags, foam, and solid buoyancy materials inside the guide frame. By adjusting the buoyancy of the guide frame and the winch blades in the water, it can achieve the cleaning of entangled materials in different spatial positions and shapes, whether they are sinking, suspended, or floating.

Detailed Implementation

[0062] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] Example 1

[0064] Reference Figure 1 A pipe measuring and cleaning device includes a connecting rod assembly 1 and a probe assembly 2, wherein the bottom of the connecting rod assembly 1 is detachably connected to the probe assembly 2, and the connection between the two constitutes a pipe measuring component, which can measure the size of the pipe.

[0065] Reference Figure 1 The connecting rod assembly 1 is composed of several connecting rod sleeves 11 connected end to end, which are detachably connected. The outer sides of two adjacent connecting rod sleeves 11 are also tightly fitted with connecting sleeve assemblies 13.

[0066] Furthermore, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 The connecting rod sleeve 11 is a hollow cylindrical structure with a scale on its outer wall for reference when measuring pipe dimensions. A transmission spindle 12 is located in the middle of the connecting rod sleeve 11 and in the vertical direction. One end of the transmission spindle 12 is connected to the upper clamp 17 and the other end is connected to the lower clamp 18. The upper clamp 17 is protruding, while the lower clamp 18 is concave, corresponding to the upper clamp 17. The upper clamp 17 can be connected to the adjacent lower clamp 18.

[0067] The outer side of the upper clamp 17 is provided with a bearing 15, and the outer side of the bearing 15 is connected to the inner wall of the connecting rod outer sleeve 11 through the bearing seat 16. An inner retaining spring 14 is provided above the bearing 15, and the other end of the inner retaining spring 14 is inserted into the bearing seat 16. The inner retaining spring 14 can play a certain anti-vibration effect when the bearing 15 is in motion.

[0068] The lower clamp 18 has the same configuration as the upper clamp 17, that is, a bearing 15 is provided on the outer side of the lower clamp 18. The outer side of the bearing 15 is connected to the inner wall of the connecting rod outer sleeve 11 through the bearing seat 16. An inner retaining spring 14 is provided above the bearing 15. The other end of the inner retaining spring 14 is inserted into the bearing seat 16. The inner retaining spring 14 can play a certain anti-vibration effect when the bearing 15 is in motion.

[0069] Furthermore, refer to Figure 6When two adjacent connecting rod sleeves 11 are connected, they can be connected end to end through the internal transmission spindle 12. That is, the upper clamp 17 on the lower transmission spindle 12 can be inserted into the lower clamp 18 on the upper transmission spindle 12. After the end is connected, the connecting sleeve assembly 13 is put on the connection point of the two connecting rod sleeves 11 and the two are fastened to complete the splicing of the two connecting rod sleeves 11.

[0070] Reference Figure 7 The connecting sleeve assembly 13 is a hollow cylindrical structure, and the inner diameter of the connecting sleeve assembly 13 is slightly larger than the outer diameter of the connecting rod outer sleeve 11, so that the connecting sleeve assembly 13 can be locked on the outside of the connecting rod outer sleeve 11. At the same time, a number of locking steel balls 132 are provided inside the connecting rod assembly 13 and at a slightly higher position. The locking steel balls 132 are elastic. When they are engaged with the connecting rod outer sleeve 11, the locking steel balls 132 are locked into the outside of the connecting rod outer sleeve 11. It should be noted that the outer wall of the connecting rod outer sleeve 11 is reserved with grooves for the connection of the locking steel balls 132. The specific number of locking steel balls 132 is determined according to actual needs and is not limited in this application. At the same time, a corresponding number of grooves are also provided on the outside of the connecting rod outer sleeve 11 to correspond to the locking steel balls 132.

[0071] Several sets of locking screws 131 are provided inside the connecting rod assembly 13 and at a lower position. When engaged with the connecting rod sleeve 11, the locking screws 131 are precisely engaged with the outer side of the connecting rod sleeve 11. The outer wall of the connecting rod sleeve 11 has a groove reserved for the connection of the locking screws 131. The specific number of locking screws 131 is determined according to actual needs and is not limited in this application. At the same time, a corresponding number of grooves are also provided on the outer side of the connecting rod sleeve 11 to correspond to the locking screws 131.

[0072] It should be noted that the locking ball 132 at the upper position of the connecting rod assembly 13 engages with the upper connecting rod sleeve 11, while the locking screw 131 at the lower position of the connecting rod assembly 13 engages with the lower connecting rod sleeve 11. This further ensures the stability of the connection between adjacent connecting rod sleeves 11 (e.g., Figure 6 (As shown).

[0073] Reference Figure 8 and Figure 9 The probe assembly 2 includes a vertically oriented pointed rod 21, a horizontally oriented transverse well probe 22, and a fixing screw 23 for connecting the two. The top of the pointed rod 21 can be connected to the connecting rod assembly 1 via the connecting sleeve assembly 13. A groove for connecting the locking screw 131 is provided on the outer wall of the pointed rod 21. The transverse well probe 22 is installed on the upper part of the pointed rod 21 in the horizontal direction via the fixing screw 23.

[0074] It should be noted that the bottom of the pointed insertion rod 21 is pointed and used to insert into the well, while the top is cylindrical and used to connect to the horizontal well probe 22; the top of the horizontal well probe 22 is horizontal and the bottom is inclined.

[0075] The measurement method for pipeline measurement and cleaning devices includes the following steps: (refer to...) Figure 10 and Figure 11 )

[0076] A1. The probe assembly 2 is installed on the lower part of the connecting rod assembly 1 through the connecting sleeve assembly 13 to form a pipeline measuring component. In this process, the length and quantity of the connecting rod can be selected according to the well depth. The connecting rod assembly 1 is selected to a suitable length and connected together through the connecting sleeve assembly 13.

[0077] A2. Then, a person stands at the vertical wellhead and vertically inserts the probe rod (i.e., the rod assembly 1 and the probe assembly 2) into the well, forcefully inserting it at several points, passing through the silt at the bottom of the well and inserting it into the horizontal well flow channel.

[0078] A3. Then find the deepest point and mark it on the ground plane at the corresponding mark A1 on the outer sleeve of the connecting rod. At this time, the vertical well depth H = H1 + A1.

[0079] A4. When the probe assembly 2 approaches the vertical well wall, the horizontal well probe 22 is rotated to detect the orientation of the horizontal well opening. The top of the horizontal well opening can block the horizontal well probe 22. At this time, the riser diameter of the probe assembly 2 is H2.

[0080] A5. Next, pull the probe assembly 2 up to the location of the horizontal well and scrape it against the upper wall of the horizontal well through the horizontal well probe 22. At this time, mark the corresponding scale A2 between the ground plane and the connecting rod sleeve 11. Then, calculate and measure the diameter DN of the horizontal well. It should be noted that the diameter of the horizontal well DN = H1 + H2, and the diameter of the horizontal well H2 = A1 - A2.

[0081] A6. Finally, develop a pipeline cleaning plan based on the dimensions measured in the vertical and horizontal shafts.

[0082] Example 2

[0083] Reference Figure 12 In Example 1, if the dimensions of the vertical and horizontal wells are measured, and cleaning of the vertical and horizontal wells is initiated, the probe assembly 2 at the bottom of the connecting rod assembly 1 in Example 1 needs to be removed. Then, the bottom of the connecting rod assembly 1 is detachably connected to the sludge removal head assembly 6 via the lower drive flexible shaft 5, and the top of the connecting rod assembly 1 is detachably connected to the electric drill 4 via the upper drive flexible shaft 3. After installation, a pipe cleaning component (such as...) can be formed. Figure 12 (As shown).

[0084] Reference Figure 13The upper drive flexible shaft 3 and the lower drive flexible shaft 5 have the same structure and principle. Taking the upper drive flexible shaft 3 as an example: the upper drive flexible shaft 3 also has a drive spindle inside, but one end of the drive spindle is connected to the first connecting end 31, and the other end is connected to the second connecting end 32 corresponding to the first connecting end 31. Specifically, the first connecting end 31 has a concave structure, which is exactly engaged with the upper clamp 17 on the connecting rod sleeve 11. The upper clamp 17 is exactly convex, corresponding to the first connecting end 31, and the second connecting end 32 is also convex. The second connecting end 32 is connected to the inner wall of the upper transmission flexible shaft 3 via bearings. Therefore, when the electric drill 4 drives the spindle inside the upper transmission flexible shaft 3, only the transmission spindle inside the upper transmission flexible shaft 3 rotates, which in turn drives the transmission spindle 12 inside the connecting rod sleeve 11 to rotate, and then drives the spindle inside the lower transmission flexible shaft 5 to rotate. This does not affect the upper transmission flexible shaft 3, the connecting rod sleeve 11, and the lower transmission flexible shaft 5, and the upper transmission flexible shaft 3, the connecting rod sleeve 11, and the lower transmission flexible shaft 5 do not rotate accordingly.

[0085] Reference Figure 12 The lower drive shaft 5 also has a drive spindle inside. The top of the drive spindle is connected to the lower clamp 18 on the connecting rod sleeve 11, and the bottom of the drive spindle is connected to the sludge removal head assembly 6. Therefore, when the drive spindle inside the lower drive shaft 5 is in motion, it will eventually drive the sludge removal head assembly 6 to rotate and clean the sludge.

[0086] Reference Figure 14 , Figure 15 and Figure 16 The dredging winch assembly 6 includes a guide frame 67 and a winch blade 63 located at one end of the guide frame 67. Both the guide frame 67 and the winch blade 63 are arc-shaped structures and are arranged in a circular array of several. The outer edge dimension of the guide frame 67 is larger than the outer edge dimension of the winch blade 63. This design can prevent the winch blade 63 from touching the pipe wall or the bottom of the pipe and causing it to be unable to rotate or even damage the parts. It should be noted that in this application, four sets of guide frames 67 and winch blades 63 are provided for reference by the staff. The specific number of sets can be determined according to the actual situation on site, and this application does not limit it.

[0087] It should be noted that, in actual use, depending on the mass, shape and spatial position of the entangled material in the pipe, components such as inflatable airbags, foam, and solid buoyancy materials can be installed in the guide frame 67. By adjusting the buoyancy of the guide frame 67 and the auger blades 63 in the water, the entangled material in different spatial positions and shapes, whether it is sinking, suspended or floating, can be cleaned.

[0088] Reference Figure 14A guide fixing sleeve 61 is installed at the center of the guide frame 67. The inner side of the guide fixing sleeve 61 is provided with a flexible shaft sleeve 62. The interior of the flexible shaft sleeve 62 is connected to the end of the lower drive flexible shaft 5 through a bearing.

[0089] The outer side of the flexible shaft sleeve 62 and on one side of the guide fixing sleeve 61 is also connected to the auger blade 63 via the second bearing 66. The end of the flexible shaft sleeve 62 is provided with a receiving plate 65 that is connected to the inner core shaft of the lower transmission flexible shaft 5. Therefore, the lower transmission flexible shaft 5 can drive the receiving plate 65 to rotate. Since the receiving plate 65 is connected to the auger blade 63, the auger blade 63 is driven to rotate. However, due to the setting of the second bearing 66, the guide frame 67 does not rotate accordingly.

[0090] The cleaning method for pipeline measurement and cleaning devices includes the following steps: (refer to...) Figure 17 , Figure 18 and Figure 19 )

[0091] B1. The upper drive flexible shaft is installed on the upper part of the connecting rod assembly and the lower drive flexible shaft is installed on the lower part of the connecting rod assembly through the connecting sleeve assembly 13. The electric drill is connected to the upper drive flexible shaft 3 and the dredging auger assembly 6 is connected to the lower drive flexible shaft 5.

[0092] B2. Subsequently, two people need to operate around the wellhead. One person holds the connecting rod assembly 1 and slowly lowers the dredging auger assembly 6 and the lower transmission flexible shaft 5 into the vertical well water surface. The other person holds the electric drill 4 and controls its operation.

[0093] B3. Then the electric drill 4 starts working and starts rotating. It drives the auger blades 63 to rotate through the transmission core shaft in the upper transmission flexible shaft 3, the connecting rod assembly 1, and the lower transmission flexible shaft 5. It stirs up and wraps the floating, suspended, and sinking linear, sheet-like, and flocculent debris in the water around the auger blades, and lifts the auger blades 63 upward to complete the cleaning of the entangled debris in the vertical well.

[0094] B4. After the vertical shaft is cleaned, place the connecting rod assembly 1 and the sludge removal head assembly 6 close to the horizontal shaft opening, slowly press down and pull the connecting rod assembly 1 in the opposite direction of the horizontal shaft opening, so that the lower transmission flexible shaft 5 bends and deforms, pushing the sludge removal head guide frame 67 to move towards the horizontal shaft. During the rotation of the head blade 63 and its entry into the horizontal shaft, the linear, sheet-like, and flocculent debris in the horizontal shaft will be wrapped around the rotating head. Remove the rotating head to complete the cleaning of the entangled material.

[0095] B5. The operator can increase or decrease the number of connecting rods at any time according to the well depth, and move the connecting rods back and forth, up and down, and around the perimeter to achieve blind-spot-free cleaning of the rotating winch head.

[0096] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
