Description

Technical Field

[0001] This utility model relates to the field of pipeline dredging technology, and in particular to a flanged rib bend with a dredging device. Background Technology

[0002] In various fluid transport systems, flanged elbows are widely used as important pipe connection components, enabling changes in pipe direction and enhancing pipe strength and stability through the ribs. However, the change in fluid flow direction at the bend reduces the flow velocity, making it easy for impurities carried in the fluid to accumulate. Over time, these impurities not only affect fluid transport efficiency but can also clog the pipe, disrupting the normal operation of the entire system. Existing cleaning methods typically require specialized tools to reach deep into the bend for cleaning. If the bend is far from the pipe inlet or outlet, cleaning tools may struggle to reach the designated location and remove accumulated impurities. Utility Model Content

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1

[0029] Reference Figures 1-7 This is the first embodiment of the present utility model. This embodiment provides a flange rib bend with a dredging device. The flange rib bend with a dredging device includes a main component 100, which includes a bend 101.

[0030] The unblocking component 200 is installed inside the bend 101 and includes an unblocking part 201. The unblocking part 201 includes a guide rail 201a, a sleeve 201b, a fixing block 201c, an expansion plate 201d, a connecting rod 201e, a moving ring 201f, and a protrusion 201g. The guide rail 201a is located inside the bend 101, the sleeve 201b is sleeved on the outside of the guide rail 201a, the fixing block 201c is fixed on the sleeve 201b, one end of the expansion plate 201d is rotatably connected to the fixing block 201c, one end of the connecting rod 201e is hinged to the expansion plate 201d, the moving ring 201f is sleeved on the sleeve 201b, one end of the connecting rod 201e is hinged to the moving ring 201f, and a moving groove 201a-1 is opened on the guide rail 201a, and the protrusion 201g slides in the moving groove 201a-1.

[0031] By setting up the unblocking component 201, the impurities accumulated on the inner wall of the bend 101 are cleaned. The guide rail 201a is located at the center of the bend 101, providing guidance for the movement of the sleeve 201b. The sleeve 201b is made of a material with a certain degree of deformation and can be bent. At the same time, the sleeve 201b and the guide rail 201a are engaged by a slot and a locking block, so that the sleeve 201b can move along the guide rail 201a, but will not rotate relative to the guide rail 201a. This ensures that the sleeve 201b can pass smoothly through the bend section 201a-3 of the guide rail 201a.

[0032] The inner wall of the moving ring 201f also has a certain deformation capacity, so as to ensure that when the sleeve 201b bends, the moving ring 201f can continue to slide along the bent part of the sleeve 201b.

[0033] The portion of the expansion plate 201d away from the fixed block 201c also has a certain deformation capacity, ensuring that when the expansion plate 201d expands, one end of the expansion plate 201d can contact the inner wall of the bend 101. When the expansion plate 201d moves to the bent part of the bend 101 along with the movement of the sleeve 201b, the deformation capacity of the end of the expansion plate 201d will not hinder the movement of the sleeve 201b. At the same time, the impurities accumulated in the bend 101 will not exert great pressure on the expansion plate 201d. When the end of the expansion plate 201d contacts the impurities, the end of the expansion plate 201d will not deform, thereby scraping the accumulated impurities off the inner wall of the bend 101.

[0034] The sleeve 201b, the fixed block 201c, the expansion plate 201d, the connecting rod 201e, and the moving ring 201f work together to form a structure similar to umbrella ribs. When the moving ring 201f slides on the sleeve 201b, the position of one end of the connecting rod 201e changes because one end of the moving ring 201f is hinged to the moving ring 201f. This changes the angle between the connecting rod 201e and the sleeve 201b. Because one end of the connecting rod 201e is hinged to the expansion plate 201d, the angle between the expansion plate 201d and the sleeve 201b changes, causing the expansion plate 201d to expand or contract. When the moving ring 201f moves away from the fixed block 201c, the expansion plate 201d contracts; when the moving ring 201f moves closer to the fixed block 201c, the expansion plate 201d expands.

[0035] The bump 201g is set to control the movement of the moving ring 201f.

[0036] Example 2

[0037] Reference Figures 1-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, a spring 201h is fixed to one side of the protrusion 201g, and the other end of the spring 201h is fixed to the inner wall of the moving groove 201a-1.

[0039] Spring 201h applies a continuous pushing force to protrusion 201g, ensuring that one end of protrusion 201g always protrudes from the end face of sleeve 201b. Spring 201h has a large elastic force, and spring 201h will not be compressed by moving ring 201f pressing protrusion 201g alone. This allows protrusion 201g to restrict the movement of moving ring 201f, thereby changing the angle between connecting rod 201e and sleeve 201b, thus changing the expansion and contraction state of expansion plate 201d.

[0040] Specifically, one end of the protrusion 201g has two inclined surfaces, namely the first inclined surface 201g-1 and the second inclined surface 201g-2, which together form the tip.

[0041] By setting two inclined planes, the moving ring 201f can move bidirectionally along the sleeve 201b.

[0042] Specifically, the sleeve 201b has a groove 201b-1, and the protrusion 201g can slide in the groove 201b-1.

[0043] Specifically, the unblocking component 200 also includes an auxiliary component 202 located on the sleeve 201b, including a first fixing ring 202a and a retaining ring 202b. The first fixing ring 202a is fixed on the sleeve 201b, and the retaining ring 202b is fixed on the guide rail 201a.

[0044] In the initial state, the protrusion 201g is located away from the first fixed ring 202a. When the sleeve 201b is pushed to move towards the bent section 201a-3, the moving ring 201f will move along with the sleeve 201b. When the end face of the moving ring 201f contacts the first inclined surface 201g-1 of the protrusion 201g, the protrusion 201g will restrict the movement of the moving ring 201f due to the large elastic force of the spring 201h. Meanwhile, the end of the connecting rod 201e that is hinged to the expansion plate 201d will continue to move, thereby increasing the angle between the connecting rod 201e and the sleeve 201b, which in turn causes the expansion plate 201d to expand, thereby cleaning the impurities accumulated on the inner wall of the bent pipe 101.

[0045] As the sleeve 201b moves, the first fixed ring 202a will gradually approach the moving ring 201f. When the two come into contact, the first fixed ring 202a will apply a pushing force to the moving ring 201f, thereby compressing the spring 201h. The protrusion 201g moves into the moving groove 201a-1, which will not hinder the movement of the sleeve 201b and the moving ring 201f. After the expansion plate 201d expands, the impurities on the inner wall of the bend 101 will also apply a pushing force to the expansion plate 201d, thereby hindering the expansion plate 201d from contracting, so that the expansion plate 201d maintains an expanded state in order to scrape off the impurities.

[0046] When the sleeve 201b is pushed to move towards the first straight segment 201a-2, the second inclined surface 201g-2 of the protrusion 201g will first contact the end face of the sleeve 201b, and the spring 201h will be squeezed. Then the protrusion 201g will slide again in the groove 201b-1 and hinder the movement of the moving ring 201f, thereby reducing the angle between the connecting rod 201e and the sleeve 201b, and thus causing the expansion plate 201d to contract.

[0047] The retaining ring 202b is used to limit the expansion state of the sleeve 201b when it moves to the end of the guide rail 201a. As the sleeve 201b moves, when the included angle between the connecting rod 201e and the sleeve 201b is at its minimum, since the length of the connecting rod 201e remains unchanged, the connecting rod 201e continues to pull the moving ring 201f to move, thereby compressing the spring 201h. The protrusion 201g will not affect the movement of the moving ring 201f, so that the moving ring 201f returns to the space between the first fixed ring 202a and the protrusion 201g.

[0048] Specifically, support plates 202c are fixed on both sides of the guide rail 201a, and the support plates 202c are fixed to the inner wall of the bend 101.

[0049] There are two support plates 202c, which are used to provide stable support for the guide rail 201a.

[0050] Example 3

[0051] Reference Figures 1-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0052] Specifically, the guide rail 201a is divided into three sections: the first straight section 201a-2, the curved section 201a-3, and the second straight section 201a-4.

[0053] In the initial state, the sleeve 201b is located on the first straight segment 201a-2. When the sleeve 201b moves from the first straight segment 201a-2 to the second straight segment 201a-4, the expansion plate 201d will expand to clean the impurities on the inner wall of the bend 101. The cleaned impurities will be located on the second straight segment 201a-4. When the sleeve 201b moves from the second straight segment 201a-4 to the first straight segment 201a-2, the harder impurities that have not been cleaned will cause the expansion plate 201d to shrink by a certain size, thereby concentrating the impurities in the second straight segment 201a-4.

[0054] Specifically, a first pull rope 202d and a second pull rope 202e are fixed on the sleeve 201b. The second pull rope 202e is located on the sleeve 201b near the curved section 201a-3.

[0055] The bend 101 has holes corresponding to the first pull rope 202d and the second pull rope 202e. A sealing ring 202g is installed in the hole to ensure the sealing of the bend 101. Pulling the first pull rope 202d can move the sleeve 201b from the second straight segment 201a-4 to the first straight segment 201a-2. Pulling the second pull rope 202e can move the sleeve 201b from the first straight segment 201a-2 to the second straight segment 201a-4.

[0056] Specifically, there are multiple expansion plates 201d, and a soft cloth 202f is provided between adjacent expansion plates 201d. The soft cloth 202f has a certain elasticity.

[0057] When multiple expansion plates 201d expand simultaneously, the soft cloth 202f will be stretched. At this time, the gaps between the expansion plates 201d are filled by the soft cloth 202f to ensure the unblocking effect.

[0058] Specifically, a hook 102 is fixed to the outside of the bend 101, and a pull ring 103 is fixed to one end of the first pull rope 202d. The pull ring 103 can be used in conjunction with the hook 102.

[0059] When cleaning is not required, pull the pull ring 103 onto the hook 102 so that the hook 102 can restrict the movement of the first pull rope 202d, thereby ensuring that the position of the sleeve 201b will not move arbitrarily.

[0060] In use, initially, sleeve 201b is located on the first straight segment 201a-2. Pulling the second pull rope 202e moves sleeve 201b from the first straight segment 201a-2 to the second straight segment 201a-4. Moving ring 201f follows sleeve 201b. When the end face of moving ring 201f contacts the first inclined surface 201g-1 of protrusion 201g, due to the large elastic force of spring 201h, protrusion 201g restricts the movement of moving ring 201f. Meanwhile, the end of connecting rod 201e hinged to expansion plate 201d continues to move, thus increasing the angle between connecting rod 201e and sleeve 201b, thereby causing expansion plate 201d to... As the sleeve 201b moves, the first fixed ring 202a will gradually approach the moving ring 201f. When the two contact, the first fixed ring 202a will apply a pushing force to the moving ring 201f, thereby compressing the spring 201h. The protrusion 201g moves into the moving groove 201a-1, thus not hindering the movement of the sleeve 201b and the moving ring 201f. After the expansion plate 201d expands, the impurities on the inner wall of the bend 101 will also apply a pushing force to the expansion plate 201d, thereby hindering the expansion plate 201d from contracting, thus keeping the expansion plate 201d in an expanded state. The soft cloth 202f and the expansion plate 201d scrape off the impurities on the inner wall of the bend 101.

[0061] Then, pulling the first rope 202d causes the sleeve 201b to move from the second straight segment 201a-4 to the first straight segment 201a-2. The second inclined surface 201g-2 of the protrusion 201g will first contact the end face of the sleeve 201b, and the spring 201h will be compressed. Then, the protrusion 201g will slide again in the groove 201b-1 and hinder the movement of the moving ring 201f, thereby reducing the angle between the connecting rod 201e and the sleeve 201b, and causing the expansion plate 201d to contract. When the angle between the connecting rod 201e and the sleeve 201b is at its minimum, since the length of the connecting rod 201e remains unchanged, the connecting rod 201e continues to pull the moving ring 201f to move, thereby compressing the spring 201h. The protrusion 201g will not affect the movement of the moving ring 201f, allowing the moving ring 201f to reset.

[0062] The inner wall of the bend 101 is cleaned by repeatedly pulling the first pull rope 202d and the second pull rope 202e. After cleaning, the pull ring 103 is pulled onto the hook 102 so that the hook 102 can restrict the movement of the first pull rope 202d, thereby ensuring that the position of the sleeve 201b will not move arbitrarily.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
