[0033] Example 1
[0034] Reference Figure 1-9 Schematic diagram of a pipe dredging machine proposed in this embodiment, including a conduit assembly 100, a roller assembly 200, a driving mechanism 300, a flexible shaft conduit 400, and a roller assembly 500, again referring to Figure 1As shown in the figure, this embodiment also includes a handheld part 600, an electric component 700, a transmission part 800, a plug 900 and a switch part 1000, wherein the catheter component 100 is installed inside the drum component 200, and is used to guide the soft shaft s stored in the drum component 200 to prevent it from being tangled inside. The driving mechanism 300 is arranged at the output end of the drum component 200, and is used to drive the soft shaft s out of the drum component 200. The soft shaft catheter 400 is detachably installed at the rear end of the driving mechanism 300. When the dredging machine is difficult to approach the dredging entrance, the user can guide the soft shaft s to the dredging entrance through the quickly detachable soft shaft catheter 400, and holding the hose is convenient for control and prevents sewage from sticking to the operator's hands; the roller assembly 500 is used to move the pipeline dredging machine, and the handheld part 600 is retractable. The height of the handheld part 600 can be raised and lowered according to the actual needs of the user. The retractable structure can be made of wire Rod or sliding telescopic, fastener-adjustable telescopic, gear and rack telescopic, etc.; the electric component 700 is used to provide the power required for the rotation of the drum component 200, and completes the transmission through the transmission member 800. In this embodiment, the transmission member 800 is shown as a belt drive. It is not difficult for those skilled in the art to find that gear transmission or a combination of the two can also be used; and the plug 900 and the switch member 1000 are used to provide power access and start-up control. Of course, it should be noted that it is not difficult for those skilled in the art to understand that the pipe cleaning machine proposed in this embodiment should also include circuit layout, electronic components, and similar modules such as corresponding working control modules, but the above technical means are all non-essential technical features of this embodiment and have nothing to do with the technical problems to be solved by this embodiment. With reference to the implicit disclosure, those skilled in the art can fully implement it in combination with existing technologies and common knowledge, so it will not be described in detail.
[0035] Furthermore, in this embodiment, the duct assembly 100 comprises a multi-directional duct 101, a limiting cylinder 102, and an inner liner 103. The multi-directional duct 101 is disposed within the limiting cylinder 102, and the inner liner 103 is disposed on the open side of the limiting cylinder 102. The limiting cylinder 102 is sleeved within the roller assembly 200, forming a sleeve structure comprising, from the inside out, the limiting cylinder 102 and the roller assembly 200. The multi-directional duct 101 is disposed within the limiting cylinder 102, and the inner liner 103 is disposed on the open side of the limiting cylinder 102.
[0036] The drum assembly 200 comprises a drum 201 and a drum cover 202. A retaining cylinder 102 is sleeved within the drum 201, forming a space m between the drum 201 and the drum cover 202 for storing a flexible shaft s. The flexible shaft s can be discharged and retracted via the multi-directional guide tube 101. The drum cover 202 is detachably mounted on the outside of the drum 201, sealing and opening the space m. The drive mechanism 300 is positioned by the mounting bracket 301 and detachably mounted to the rear of the guide tube assembly 100. The flexible shaft guide tube 400 is detachably mounted to the rear of the drive mechanism 300.
[0037] More specifically, to solve the knotting problem, the multi-directional conduit 101 is an "S"-shaped bend tube having at least two bends 101a, and adjacent bends 101a are located on different planes. The multi-directional conduit 101 also includes a tail 101b, and the limiting cylinder 102 includes a limiting opening 102a; wherein the tail 101b passes through the limiting opening 102a to communicate with the space m, and the pipe axis of the tail 101b tends to be tangent to the wall of the limiting cylinder 102. Further, referring to Figure 5 As shown in the figure, the optimal solution in this embodiment is to divide the multi-directional conduit 101 into a first tube 101d, a second tube 101e, and a third tube 101f. The three sections can be welded or integrated. The first and second tubes 101d, 101e have a first connecting surface 101d-1, and the second and third tubes 101e, 101f have a second connecting surface 101e-1. The first and third tubes 101d, 101f are projected horizontally at a 140-degree angle. The second tube 101e is projected horizontally to form an arc with a radius of 76.2 mm from the tube axis to the center. The first connecting surface 101d-1 and the second connecting surface 101e-1 are projected horizontally at a 40-degree angle.
[0038] In simple terms, the conduit is to be brought as close as possible to the outside of the drum (i.e., the roller assembly 200) so that the flexible shaft s can be stored in a smaller space, constraining the flexible shaft s from twisting in space and preventing it from getting tangled. The traditional conduit only has a curvature in a radial direction from the center of the drum. If it is close to the outside of the drum, the flexible shaft s cannot immediately spiral within a small radius. Therefore, it cannot be made too close to the outside of the drum, leaving redundant space for the flexible shaft to spiral, and thus leaving hidden danger space for the flexible shaft to get tangled. In this embodiment, the original curvature in a radial direction from the center of the drum is changed in advance to a transition in a tangential direction to the outside of the drum, and at the same time, an annular partition as large as the outermost side of the conduit, i.e., the lining 103, is provided, thereby reducing the redundant space for the flexible shaft s to get tangled.
[0039] In order to reduce the redundant space for the flexible shaft s to be knotted, the lining 103 is an isolation plate whose two ends are in conflict with the opening edge of the limiting cylinder 102. At the same time, the lining 103 is set inward from the opening edge of the limiting cylinder 102. The inward distance is the depth for the ring plate 201a to be embedded in the limiting cylinder 102. When the ring plate 201a is embedded in the limiting cylinder 102, since the length of the lining 103 corresponds to the diameter of the limiting cylinder 102, there is a space m for storing the flexible shaft s between the limiting cylinder 102 and the roller 201, as well as a gap between the ring plate 201a and the limiting cylinder 102 due to different diameters, the flexible shaft s is prevented from entering the gap. The lining 103 is set to block it and confine the flexible shaft s to the space m.
[0040] It should be noted that, in this embodiment, the inner diameter of the limiting cylinder 102 can be changed to form different specifications of the limiting cylinder 102. When the inner diameter of the limiting cylinder 102 is larger than the inner diameter of the ring plate 201a, the ring plate 201a is embedded in the limiting cylinder 102 and contacts the liner 103 for limiting position. When the inner diameter of the limiting cylinder 102 is smaller than the inner diameter of the ring plate 201a, the opening side of the limiting cylinder 102 is embedded in the ring plate 201a, and the flexible shaft s is wound around the ring plate 201a. or when the inner diameter of the limiting cylinder 102 is equal to the inner diameter of the ring plate 201a, the opening side of the limiting cylinder 102 is in conflict with the edge of the ring plate 201a for limiting the position, that is, the outer wall of the limiting cylinder 102 and the side wall of the ring plate 201a coincide with each other, and the two are on the same surface and conflict with each other. There is no longer a gap between the ring plate 201a and the limiting cylinder 102. The setting of the ring plate 201a facilitates the installation and stability of the positioning limiting cylinder 102.
[0041] Furthermore, in this embodiment, the roller assembly 200 also includes a turntable 203 and a fixed shaft 204; wherein the turntable 203 is rotatably arranged on the fixed shaft 204, the roller 201 is installed on the turntable 203 and can rotate with the turntable 203, and the limiting cylinder 102 is fixed to the fixed shaft 204 through the lining 103. Since the lining 103 and the limiting cylinder 102 are fixedly connected, the limiting cylinder 102 cannot rotate. At this time, after the turntable 203 rotates, the roller 201 rotates and the limiting cylinder 102 is fixed, that is, the roller 201 rotates relative to the limiting cylinder 102, and the soft shaft s stored therein can be rotated out. If it needs to be retracted, it can be completed by rotating in the opposite direction.
[0042] It should be noted that this is the installation of the rear end of the drum assembly 200. It is not difficult to understand that the front end of the drum assembly 200 also needs to be fixedly supported and installed.
[0043] Therefore, in this embodiment, to facilitate the installation of both the roller cover 202 and the limiting cylinder 102, the multi-directional guide 101 further includes an extension 101c, and the limiting cylinder 102 includes a shaft 102b. The extension 101c extends outward from the limiting cylinder 102, and the shaft 102b is sleeved on the extension 101c. The roller cover 202 includes at least one mounting portion 202a, which is fixedly sleeved on the shaft 102b and detachably mounted on the roller 201. The roller cover 202 can rotate about the shaft 102b, while the limiting cylinder 102 and the extension 101c are fixedly mounted and cannot rotate. The extension 101c and the shaft 102b here not only act in opposition but also serve to secure and support the roller assembly 200.
[0044] Furthermore, in order to realize a split drum and a split frame that are easy for users to disassemble, when the flexible shaft is knotted, the user can disassemble the drum cover by himself for easy maintenance and processing, and an installation bracket 301 is adopted. Specifically, the installation bracket 301 includes an axle seat 301a, a support seat 301b, a front support rod 301c and a rear support rod 301d; wherein the axle seat 301a is connected to the axis of the limiting cylinder 102 at the top and fixedly connected to the front support rod 301c at the bottom, the bottom of the support seat 301b is located outside the bottom of the axle seat 301a and is detachably connected by a fastener 301e, and the top of the support seat 301b is connected to the driving mechanism 300; the front support rod 301c is provided with an embedded portion 301c-1, and the rear support rod 301d is provided with a joint portion 301d-1, and the embedded portion 301c-1 is embedded in the joint portion 301d-1 and is connected by a fastener 301e. Here, after the roller cover 202 is sleeved on the shaft column 102 b , the shaft seat 301 a is sleeved on the roller cover 202 , which not only plays the role of shaft connection, but also has a supporting function for the roller assembly 200 .
[0045] It should be noted that the fasteners 301e, i.e., bolts, are used between the shaft seat 301a, the support seat 301b, and the front support rod 301c. Alternatively, a detachable fastener or other fastener may be used. When the drive mechanism 300 is no longer needed, the drive mechanism 300 can be removed and the flexible shaft conduit 400 can be directly connected to the shaft seat 301a for manual operation. The drive mechanism 300, which is driven by the flexible shaft s, is detachable, saving packaging space and adapting to manual models for upgrading to models with automatic delivery. It can also tighten the screw head that secures the support seat 301b and can be used to position the drive mechanism 300, achieving multi-functionality. At the same time, the roller 201 is also connected to the mounting portion 202a on the roller cover 202 via the fastening holes 201b and the fasteners 301e.
[0046] Furthermore, in order to reduce the packaging space, facilitate transportation and storage, and facilitate passing through a narrow space, and when the dredging machine is not easy to approach the dredging entrance, the user can guide the flexible shaft s to the dredging entrance, and hold the hose for easy control, and prevent sewage from sticking to the operator's hands. In this embodiment, the flexible shaft catheter 400 includes a connector 401, which is sleeved on the pipe mouth of the driving mechanism 300, and the two are detachably fastened by a latch 402. It is not difficult to understand that the connector 401 is a sleeve with an opening, which can be directly sleeved on the output pipe mouth of the driving mechanism 300, and the connector 401 is connected by inserting the latch 402, or the connector 401 can be rotated to connect to the output pipe mouth of the driving mechanism 300 by threaded engagement, so that the flexible shaft catheter 400 can be freely disassembled.
[0047] In this embodiment, the roller assembly 500 is arranged on the inner side of the two rear support rods 301d to reduce the packaging space, facilitate transportation and storage, and facilitate passing through a narrow space.
[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The embodiments should be considered as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description.
