Description

Technical Field

[0001] This utility model relates to the field of pipeline dredging technology, and in particular to a pipeline cleaning device and pipeline cleaning components. Background Technology

[0002] Municipal drainage pipes, as a crucial component of urban infrastructure, are responsible for the timely removal of rainwater and domestic sewage. Since most municipal drainage pipes are non-powered, relying on the pipe's slope to provide the flow of water, and because rainwater and sewage contain significant amounts of silt and debris, these substances tend to accumulate at the pipe openings during drainage, leading to blockages over time. Furthermore, the constantly damp environment at pipe openings makes them susceptible to the growth of weeds and tree roots, which can also cause blockages. Therefore, regular dredging and cleaning of drainage pipes are essential.

[0003] Currently, due to the limited location of the pipelines, existing pipeline cleaning devices cannot effectively clean the pipeline openings. Utility Model Content

[0004] The main purpose of this utility model is to propose a pipe cleaning device and pipe cleaning components, which aims to solve the current technical problem that it is not convenient to effectively clean pipe openings and unclog pipes.

[0005] To achieve the above objectives, this utility model proposes a pipe cleaning device, comprising:

[0006] A connecting rod having multiple connecting segments, with adjacent connecting segments connected by hinges to allow relative bending along the vertical axis of the connecting rod between adjacent connecting segments;

[0007] A drain cleaner is disposed at one end of the connecting rod and is configured to deflect relative to the connecting segment along the vertical axis of the connecting rod.

[0008] In some embodiments, the hinge includes a first hinge portion and a second hinge portion pivotally connected to each other, the first hinge portion being connected to one of the connecting segments, and the second hinge portion being connected to an adjacent connecting segment;

[0009] The first hinge portion is provided with a rotating portion, and the second hinge portion is provided with a rotating abutment member. The rotating abutment member and the rotating portion have an abutment state and a separation state. In the abutment state, the rotating abutment member abuts against the outer periphery of the rotating portion. In the separation state, the rotating abutment member and the rotating portion are separated.

[0010] In some embodiments, the first hinge portion is provided with a first connecting hole, and the connecting segment connected to the first hinge portion is provided with a second connecting hole. The second connecting hole and the first connecting hole are provided correspondingly, and a first connecting member is sequentially inserted into the first connecting hole and the second connecting hole. The first connecting member connects the first hinge portion and the connecting segment.

[0011] The second hinge portion is provided with a third connecting hole, and the connecting segment connected to the second hinge portion is provided with a fourth connecting hole. The fourth connecting hole and the third connecting hole are provided correspondingly. A second connecting member is sequentially inserted into the third connecting hole and the fourth connecting hole, and the second connecting member connects the second hinge portion and the connecting segment.

[0012] In some embodiments, both the first connecting hole and the second connecting hole are provided with internal threads, the first connector is provided with external threads, and the first connector is threadedly connected to the first connecting hole and the second connecting hole;

[0013] Both the third and fourth connecting holes are provided with internal threads, and the second connector is provided with external threads. The second connector is threadedly connected to the third and fourth connecting holes.

[0014] In some embodiments, the first hinge portion is provided with a first snap-fit ​​member, and the connecting segment connected to the first hinge portion is provided with a second snap-fit ​​member. The second snap-fit ​​member and the first snap-fit ​​member can snap together to achieve snap-fit ​​between the first hinge portion and the connecting segment.

[0015] The second hinge portion is provided with a third snap-fit ​​member, and the connecting segment connected to the second hinge portion is provided with a fourth snap-fit ​​member. The fourth snap-fit ​​member and the third snap-fit ​​member can snap together to achieve snap-fit ​​between the second hinge portion and the connecting segment.

[0016] In some embodiments, the unblocking component is provided with an unblocking port, which is adapted to allow high-pressure gas or high-pressure liquid to pass through. The unblocking port is configured to deflect relative to the connecting segment along the vertical axis of the connecting rod.

[0017] In some embodiments, the end of the connecting rod is provided with a snap-fit ​​groove, and the unblocking component snaps into the snap-fit ​​groove.

[0018] In some embodiments, the angle α at which two adjacent connecting segments bend along the vertical axis of the connecting rod satisfies: 0°≤α≤90°.

[0019] In some embodiments, an operating handle is provided at the end of the connecting rod away from the unblocking component, and the operating handle is provided with a buffer.

[0020] Correspondingly, this utility model also proposes a pipe cleaning assembly, comprising:

[0021] The pipe cleaning device described in any of the above embodiments;

[0022] A positioning device is provided with a positioning groove, and the pipe cleaning device is engaged in the positioning groove.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] In this invention, when the pipe cleaning device is needed to unclog a pipe opening, the corresponding connecting sections are folded, causing them to bend relative to each other. This bending of the connecting sections then causes the unclogging component to deflect relative to the vertical axis of the connecting rod. For example, the bending of the connecting sections causes the unclogging component to deflect 90 degrees along the vertical axis of the connecting rod, ensuring that the unclogging component is aligned with the pipe opening to be cleaned. Then, the connecting rod is held and a certain external force is applied, causing the connecting rod to move the unclogging component, ensuring that the unclogging component can remove mud, debris, weeds, tree roots, etc., accumulated at the pipe opening, thus unclogging the pipe. When the pipe cleaning device is not needed, both adjacent connecting sections can be folded completely, reducing the overall size of the pipe cleaning device for easier storage.

[0025] In this invention, the pipe cleaning device effectively solves the problem of pipe unblocking by working in concert with a connecting rod and a drain cleaner. Specifically, the connecting rod consists of multiple relatively bendable connecting segments, which can be freely adjusted in shape according to the bending shape of the pipe or the position of the pipe opening, thereby adapting to the needs of different curved pipes. The drain cleaner is located at one end of the connecting rod and can be relatively deflected with the connecting segments, ensuring that the drain cleaner can be aligned with the pipe opening of the curved pipe or can enter the interior of a narrow or curved pipe for cleaning. For example, when the drain cleaner is a high-pressure water flushing device, it can efficiently clean the deposits accumulated at the pipe opening or inside the pipe; when the drain cleaner is a cleaning hook, it can physically scrape away debris at the pipe opening or inside the pipe. In actual use, the operator adjusts the relative angles between the connecting segments of the connecting rod and the angle of the drain cleaner so that the pipe cleaning device can be aligned with the pipe opening and smoothly inserted into the pipe, using the drain cleaner to clean the pipe, thereby ensuring smooth drainage. This pipe cleaning device has a simple structure and is easy to operate. It can adaptively adjust the relative position of the unblocking parts according to the location of the pipe, thereby facilitating the unblocking of the pipe.

[0026] When using the above-mentioned pipe cleaning components to clean pipe openings, stability and cleaning effectiveness can be guaranteed during the cleaning process. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Municipal drainage pipes, as a crucial component of urban infrastructure, are responsible for the timely removal of rainwater and domestic sewage. Since most municipal drainage pipes are non-powered, relying on the pipe's slope to provide the flow of water, and because rainwater and sewage contain significant amounts of silt and debris, these substances tend to accumulate at the pipe openings during drainage, leading to blockages over time. Furthermore, the constantly damp environment at pipe openings makes them susceptible to the growth of weeds and tree roots, which can also cause blockages. Therefore, regular dredging and cleaning of drainage pipes are essential.

[0049] Currently, due to the limited location of the pipelines, existing pipeline cleaning devices cannot effectively clean the pipeline openings.

[0050] Therefore, in order to solve the current technical problems of inconvenient and ineffective cleaning of pipe openings and unblocking pipes, referring to Figures 1 to 4 This utility model provides a pipe cleaning device 10, which includes a connecting rod 100 and a drain cleaning component 200. The connecting rod 100 has multiple connecting segments 110, and adjacent connecting segments 110 are connected by hinges 120, allowing them to bend relative to each other along the vertical axis of the connecting rod 100. The drain cleaning component 200 is located at one end of the connecting rod 100 and is configured to deflect relative to the connecting segments 110 along the vertical axis of the connecting rod 100. For example, the drain cleaning component 200 can be a high-pressure flushing device. Alternatively, the drain cleaning component 200 can be a cleaning hook.

[0051] Specifically, in this embodiment, when the pipe cleaning device 10 is needed to unclog a pipe opening, the corresponding connecting segment 110 is folded, causing the connecting segment 110 to bend relative to each other. This bend in the connecting segment 110 causes the unclogging component 200 to deflect relative to the vertical axis of the connecting rod 100. For example, the bend in the connecting segment 110 causes the unclogging component 200 to deflect 90 degrees along the vertical axis of the connecting rod 100, ensuring that the unclogging component 200 is aligned with the pipe opening to be cleaned. Then, the connecting rod 100 is held, and a certain external force is applied to it, causing the connecting rod 100 to move the unclogging component 200, ensuring that the unclogging component 200 can remove mud, debris, weeds, tree roots, etc., accumulated at the pipe opening, thus unclogging the pipe. When the pipe cleaning device 10 is not needed, both adjacent connecting segments 110 can be folded completely, reducing the overall size of the pipe cleaning device 10 for easier storage.

[0052] In this embodiment, the pipe cleaning device 10 effectively solves the problem of pipe unblocking by working in concert with the connecting rod 100 and the unblocking component 200. Specifically, the connecting rod 100 is composed of multiple relatively bendable connecting segments 110, which can be freely adjusted in shape according to the bending shape of the pipe or the position of the pipe opening, thereby adapting to the needs of different curved pipes. The unblocking component 200 is disposed at one end of the connecting rod 100 and can be relatively deflected with the connecting segments 110, ensuring that the unblocking component 200 can be aligned with the pipe opening of the curved pipe or can enter the interior of a narrow or curved pipe for cleaning. For example, when the unblocking component 200 is a high-pressure water flushing device, it can efficiently clean the deposits accumulated at the pipe opening or inside the pipe; when the unblocking component 200 is a cleaning hook, it can physically scrape away debris at the pipe opening or inside the pipe. In practical use, the operator adjusts the relative angles between the connecting segments 110 of the connecting rod 100 and the angle of the unblocking component 200 to ensure that the pipe cleaning device 10 is aligned with the pipe opening and smoothly extends into the pipe. The unblocking component 200 is then used to clean the pipe, thus ensuring unobstructed drainage. This pipe cleaning device 10 has a simple structure and is easy to operate. It can adaptively adjust the relative position of the unblocking component 200 according to the pipe's location, facilitating the unblocking of the pipe.

[0053] In some embodiments, refer to Figures 1 to 3 The hinge 120 includes a first hinge portion 121 and a second hinge portion 122 pivotally connected to each other. The first hinge portion 121 is connected to one of the connecting segments 110, and the second hinge portion 122 is connected to the other adjacent connecting segment 110. The first hinge portion 121 is provided with a rotating portion 1211, and the second hinge portion 122 is provided with a rotating abutment member 1221. The rotating abutment member 1221 and the rotating portion 1211 have an abutting state and a separated state. In the abutting state, the rotating abutment member 1221 abuts against the outer periphery of the rotating portion 1211. In the separated state, the rotating abutment member 1221 and the rotating portion 1211 are separated.

[0054] Specifically, in this embodiment, the first hinge portion 121 and the second hinge portion 122 are respectively connected to two adjacent connecting segments 110, ensuring the rotational flexibility between the two adjacent connecting segments 110. The first hinge portion 121 is provided with a rotating portion 1211 for realizing rotational movement, while the rotating abutment member 1221 on the second hinge portion 122 can control the relative movement state between the two adjacent connecting segments 110 by abutting or disengaging from the rotating portion 1211. When the rotating abutment member 1221 and the rotating portion 1211 are in the abutting state, the rotating abutment member 1221 will firmly abut against the rotating portion 1211, so that the two adjacent connecting segments 110 remain fixedly connected, thereby realizing the positioning of the unblocking member 200 at a certain adjustment angle or position. When the rotating abutment 1221 and the rotating part 1211 are in a separated state, the rotating abutment 1221 will maintain a certain distance from the rotating part 1211, so that the rotating abutment 1221 no longer restricts the rotation of the rotating part 1211, thereby realizing the rotational bending between the two adjacent connecting segments 110 again. For example, the rotating abutment 1221 may be fitted with an elastic member. When an outward pulling force is applied to the rotating abutment 1221, the rotating abutment 1221 will move away from the rotating part 1211, so that the rotating abutment 1221 and the rotating part 1211 switch from an abutment state to a separated state, ensuring that the two adjacent connecting segments 110 can be flexibly adjusted. When the external force applied to the rotating abutment 1221 disappears, the rotating abutment 1221 can automatically reset under the action of the elastic element. That is, under the drive of the elastic element, the rotating abutment 1221 will move towards the rotating part 1211 and abut against the outer periphery of the rotating part 1211 again, so that the rotating abutment 1221 and the rotating part 1211 switch from a separated state to an abutment state, ensuring that the two adjacent connecting segments 110 can be positioned.

[0055] It should be noted that the hinge 120 is a conventional structure in the art, and the structural design and operating principle of the hinge 120 can be referred to the prior art.

[0056] In some embodiments, the first hinge portion 121 is provided with a first connecting hole (not shown in the figure), and the connecting segment 110 connected to the first hinge portion 121 is provided with a second connecting hole (not shown in the figure). The second connecting hole and the first connecting hole are correspondingly provided, and a first connecting member is sequentially inserted into the first connecting hole and the second connecting hole, connecting the first hinge portion 121 and the connecting segment 110. For example, the first connecting hole and the second connecting hole are both provided with internal threads, and the first connecting member is provided with external threads (for example, the first connecting member can be a bolt), and the first connecting member is threadedly connected to the first connecting hole and the second connecting hole.

[0057] Specifically, in this embodiment, the first hinge portion 121 and the connecting segment 110 adopt a threaded connection structure. On the one hand, the connection is simple and can realize a detachable connection between the first hinge portion 121 and the connecting segment 110, which facilitates the assembly and disassembly of the first hinge portion 121 and the connecting segment 110 and saves the assembly time between the first hinge portion 121 and the connecting segment 110. On the other hand, the connection is stable and can ensure the connection stability between the first hinge portion 121 and the connecting segment 110, preventing the first hinge portion 121 and the connecting segment 110 from easily loosening.

[0058] Similarly, the second hinge portion 122 is provided with a third connecting hole (not shown in the figure), and the connecting segment 110 connected to the second hinge portion 122 is provided with a fourth connecting hole (not shown in the figure). The fourth connecting hole and the third connecting hole are provided correspondingly, and a second connecting member is sequentially inserted into the third connecting hole and the fourth connecting hole, connecting the second hinge portion 122 and the connecting segment 110. For example, the third connecting hole and the fourth connecting hole are both provided with internal threads, and the second connecting member is provided with external threads (for example, the second connecting member can be a bolt), and the second connecting member is threadedly connected to the third connecting hole and the fourth connecting hole.

[0059] Specifically, referring to the above embodiment, the second hinge portion 122 and the connecting segment 110 adopt a threaded connection structure. On the one hand, the connection is simple and can realize a detachable connection between the second hinge portion 122 and the connecting segment 110, which facilitates the assembly and disassembly of the second hinge portion 122 and the connecting segment 110 and saves the assembly time between the second hinge portion 122 and the connecting segment 110. On the other hand, the connection is stable and can ensure the connection stability between the second hinge portion 122 and the connecting segment 110, preventing the second hinge portion 122 and the connecting segment 110 from easily loosening.

[0060] In some embodiments, the first hinge portion 121 is provided with a first snap-fit ​​member (not shown in the figure), and the connecting segment 110 connected to the first hinge portion 121 is provided with a second snap-fit ​​member (not shown in the figure). The second snap-fit ​​member and the first snap-fit ​​member can snap together to achieve a snap-fit ​​connection between the first hinge portion 121 and the connecting segment 110. For example, the first snap-fit ​​member can be a snap-fit ​​groove, and the second snap-fit ​​member can be a snap-fit ​​protrusion. Alternatively, the first snap-fit ​​member can be a snap-fit ​​protrusion, and the second snap-fit ​​member can be a snap-fit ​​groove.

[0061] Specifically, in this embodiment, the first hinge portion 121 and the connecting segment 110 adopt a snap-fit ​​structure. On the one hand, this helps to ensure the structural stability of the first hinge portion 121 and the connecting segment 110, and realizes quick installation and disassembly and non-destructive connection between the first hinge portion 121 and the connecting segment 110. On the other hand, it helps to reduce the connection difficulty between the first hinge portion 121 and the connecting segment 110, and the connection and fixation of the first hinge portion 121 and the connecting segment 110 can be achieved without the need for additional tools.

[0062] Similarly, the second hinge portion 122 is provided with a third snap-fit ​​member (not shown in the figure), and the connecting segment 110 connected to the second hinge portion 122 is provided with a fourth snap-fit ​​member (not shown in the figure). The fourth snap-fit ​​member and the third snap-fit ​​member can snap together to achieve snap-fit ​​between the second hinge portion 122 and the connecting segment 110. For example, the third snap-fit ​​member can be a snap-fit ​​groove, and the fourth snap-fit ​​member can be a snap-fit ​​protrusion. Alternatively, the third snap-fit ​​member can be a snap-fit ​​protrusion, and the fourth snap-fit ​​member can be a snap-fit ​​groove.

[0063] Specifically, referring to the above embodiment, the second hinge portion 122 and the connecting segment 110 adopt a snap-fit ​​structure. On the one hand, this helps to ensure the structural stability of the second hinge portion 122 and the connecting segment 110, and realizes quick installation and disassembly and non-destructive connection between the second hinge portion 122 and the connecting segment 110. On the other hand, it helps to reduce the connection difficulty between the second hinge portion 122 and the connecting segment 110, and the connection and fixation of the second hinge portion 122 and the connecting segment 110 can be achieved without the need for additional tools.

[0064] In some embodiments, the first hinge portion 121 and the second hinge portion 122 can both be welded together with the connecting segment 110.

[0065] In some embodiments, refer to Figure 1 and Figure 4 The unblocking component 200 is provided with an unblocking port 210, which is suitable for introducing high-pressure gas or high-pressure liquid. The unblocking port 210 is configured to deflect relative to the vertical axis of the connecting rod 100 along the connecting segment 110. Specifically, in this embodiment, when using this pipe cleaning device 10 to unclog a pipe, the connecting rod 100 is first bent so that the unblocking port 210 of the unblocking component 200 is aligned with the pipe opening to be cleaned. Then, high-pressure gas or high-pressure liquid is blown out of the unblocking port 210. The high-pressure gas or high-pressure liquid can blow away or flush away the mud, sand, impurities, etc. accumulated at the pipe opening, thereby unblocking the pipe. By injecting high-pressure gas or high-pressure liquid, combined with the deflection movement of the unblocking component 200, a highly efficient and flexible pipe unblocking effect is achieved.

[0066] In some embodiments, the end of the connecting rod 100 is provided with a snap-fit ​​groove (not shown in the figure), and the drain cleaner 200 snaps into the snap-fit ​​groove. Specifically, in this embodiment, the engagement between the drain cleaner 200 and the snap-fit ​​groove enables the assembly and installation of the drain cleaner 200 and the connecting rod 100, allowing the drain cleaner 200 to rotate relative to the vertical axis of the connecting rod 100, so that the drain cleaner 200 can be aligned with the pipe opening to be cleaned. Alternatively, in other embodiments, the drain cleaner 200 can be welded to the end of the connecting rod 100. By welding the drain cleaner 200 to the end of the connecting rod 100, the connection strength between the drain cleaner 200 and the connecting rod 100 can be improved, preventing the drain cleaner 200 from falling off the connecting rod 100 during the cleaning of the pipe opening.

[0067] In some embodiments, the bending angle α between two adjacent connecting segments 110 along the vertical axis of the connecting rod 100 satisfies: 0° ≤ α ≤ 90°. For example, the value of α can be 0°, 30°, 45°, 60°, 90°, etc. Specifically, in this embodiment, depending on the location of the pipe opening, the connecting rod 100 can be bent to a corresponding angle so that the unblocking component 200 can be aligned with the pipe opening, facilitating the cleaning and unblocking of the pipe using the unblocking component 200.

[0068] In some embodiments, an operating handle (not shown in the figure) is provided at the end of the connecting rod 100 away from the drain cleaning component 200, and the operating handle is provided with a buffer. For example, the buffer can be a rubber sleeve or the like. Specifically, in this embodiment, by providing an operating handle, it is easier for the operator to hold and operate the pipe cleaning device 10. By providing a buffer on the operating handle, it is beneficial to improve the grip comfort of the operating handle and prevent the operating handle from scratching the operator's hands. More preferably, the surface of the buffer can be provided with anti-slip patterns or the like. The anti-slip patterns help to increase the friction between the buffer and the operator's hand, so that the operator can grip the buffer more easily.

[0069] Correspondingly, another embodiment of this utility model also provides a pipe cleaning assembly, which includes the pipe cleaning device 10 in any of the above embodiments. (Refer to...) Figure 5 The pipe cleaning assembly also includes a positioning device 300, which has a positioning groove 310, and the pipe cleaning device 10 is snapped into the positioning groove 310.

[0070] Specifically, in this embodiment, when the pipe cleaning device 10 cleans the pipe opening, the pipe cleaning device 10 can be pre-engaged in the positioning groove 310 of the positioning device 300 (specifically, one end of the pipe cleaning device 10 with the unblocking component 200 is engaged in the positioning groove 310 of the positioning device 300). Through the cooperation between the pipe cleaning device 10 and the positioning groove 310, the positioning device 300 can be used to restrict the displacement of the pipe cleaning device 10, prevent the pipe cleaning device 10 from shaking randomly during the cleaning process, and ensure the stability of the pipe cleaning device 10 when cleaning the pipe opening.

[0071] Thanks to the improvements to the pipe cleaning device 10 described above, the pipe cleaning assembly of this embodiment has the same technical effects as the pipe cleaning device 10 described above, which will not be repeated here.

[0072] It should be noted that other contents of the pipe cleaning device 10 and pipe cleaning components disclosed in this utility model can be found in the prior art, and will not be repeated here.

[0073] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
