Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipeline butt joint device for water conservancy projects. Background Art
[0002] In the construction of water conservancy projects, a docking device is often needed to dock two water pipes with exposed ends. The existing docking means often adopts the form of plug-in connection to allow the pipelines of the two water pipes to communicate. However, the existing pipe docking device has the following defects in actual use:
[0003] 1. Lack of adjustability. In actual operation, the sizes of water pipes that need to be docked may be different, and the ports of existing docking devices are often fixed in size and can only be adapted to dock water pipes of the same diameter. When water pipes of different diameters need to be docked, it is difficult to adapt;
[0004] 2. Lack of anti-leakage design. After the water pipe is combined with the docking device, the pipe body of the docking device only surrounds the water pipe, and there are obvious side seams. Once water flows, the side seams are stretched open under the action of water pressure, and water leakage is likely to occur at the joint between the docking device and the water pipe, reducing the use effect of the device.
[0005] Therefore, in the construction of water conservancy projects, there is an urgent need for a pipeline docking device that can solve the above problems. Utility Model Content
[0006] In order to overcome the above technical problems, the purpose of the utility model is to provide a pipe docking device for water conservancy projects to solve the problems of lack of adjustability and anti-leakage design of the pipe docking device in actual use.
[0007] The purpose of the utility model can be achieved through the following technical solutions:
[0008] A pipe docking device for water conservancy projects, comprising a docking piece and an anti-seepage piece;
[0009] The butt joint includes a hoop, a notch and a locking structure. The hoop is provided with a notch, and the locking structure is matched with the notch. After two sets of water pipe fittings are inserted into the hoop in opposite directions, the notch is tightened under the action of the locking structure to achieve butt joint of the water pipe fittings.
[0010] The anti-seepage component includes a barrier ring, a first conical cover, a second conical cover, a top block, a tightening strip, a sleeve and a top rod. The first conical cover and the second conical cover are respectively fixedly connected to the front side and the rear side of the barrier ring. Top blocks are fixedly installed on the first conical cover and the second conical cover. The top blocks on the opposite sides are fixedly connected with the tightening strip. The sleeve is fixed on the outer wall of the barrier ring. The top rod is slidably connected to the sleeve, and the top rod is squeezed and matched with the tightening strip.
[0011] When the tie strip is squeezed and stretched outward, the first conical cover and the second conical cover are pulled relatively close to each other, so that the barrier ring at the center is squeezed inward to form a sealed barrier area outside the water pipe.
[0012] As a further solution of the utility model: the locking structure includes a convex plate, a first cross bar, a second cross bar, a connecting rod, an external thread and a bolt. The convex plate is symmetrically fixed on the hoop, the first cross bar and the second cross bar are both fixed in the convex plate, the first cross bar is fixedly connected to the connecting rod, the connecting rod is slidably inserted relative to the second cross bar, and the connecting rod extending out of the second cross bar is provided with an external thread on one end, and the bolt is engaged with the external thread.
[0013] As a further solution of the utility model: the hoop is made of elastic stainless steel sheet.
[0014] As a further solution of the utility model: an inner liner is fixedly sleeved in the hoop, and the inner liner is in a circular ring shape. When the water pipe fitting is installed, the inner liner is tightly attached to the water pipe fitting as the hoop is tightened.
[0015] As a further solution of the utility model: barrier strips are symmetrically fixed in the lining, and the barrier strips are in a circular ring shape and protrude relative to the inner wall of the lining.
[0016] As a further solution of the utility model: the anti-seepage part also includes a limit sleeve, a locking pin and a spring. The limit sleeve is fixed on the tightening strip, and a locking pin is rotatably installed on the top of the push rod. The locking pin is snap-fitted with the limit sleeve. One end of the spring is fixedly connected to the push rod, and the other end is fixed in the sleeve.
[0017] As a further solution of the utility model: the inner lining is made of polyvinyl chloride diaphragm material.
[0018] Beneficial effects of the utility model:
[0019] 1. Since the hoop interface has a notch on one side, and the hoop itself is made of elastic stainless steel sheet, the size of the space enclosed by the hoop will change as the end of the notch approaches or moves away from each other, so that it can adapt to the fastening and docking of water pipes of different diameters.
[0020] 2. When the tie strip is squeezed and stretched outward, the first conical cover and the second conical cover are pulled relatively close to each other, so that the barrier ring at the center is squeezed inward, forming a sealed barrier area outside the water pipe fitting. The barrier area is drum-shaped, and the first conical cover and the second conical cover are pressed and fitted against the water pipe fitting, so that the existing joints can be further sealed comprehensively and effectively.

DETAILED DESCRIPTION
[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.
[0034] The applicant found that the general docking device has the disadvantage of lacking adjustability when docking pipes, which is very inconvenient when the user wants to change the diameter of the docked pipe. The applicant further found that in the actual process of pipe docking, there is still a situation where the joint between the water pipe and the docking device is prone to water leakage, and the existing docking device lacks relevant improvement settings. When the docking is completed and water is passed, the joint is easily stretched open under the action of water pressure, causing water leakage.
[0035] In view of this, the embodiment of the present application provides a technical solution, referring to Figures 1 to 9 , a pipe docking device for water conservancy engineering, comprising a docking piece 2 and an anti-seepage piece 3;
[0036] The docking member 2 includes a hoop 201, a notch 202 and a locking structure. The hoop 201 is provided with a notch 202, and the locking structure is matched with the notch 202. After two sets of water pipe fittings 1 are inserted into the hoop 201 in opposite directions, the notch 202 is tightened under the action of the locking structure to achieve docking of the water pipe fittings 1.
[0037] The anti-seepage member 3 includes a barrier ring 301, a first conical cover 302, a second conical cover 303, a top block 304, a tie strip 305, a sleeve 306 and a top rod 307. The first conical cover 302 and the second conical cover 303 are respectively fixedly connected to the front side and the rear side of the barrier ring 301. The top block 304 is fixedly installed on the first conical cover 302 and the second conical cover 303. The tie strip 305 is fixedly connected between the top blocks 304 on the opposite sides. The sleeve 306 is fixed on the outer wall of the barrier ring 301. The top rod 307 is slidably connected to the sleeve 306, and the top rod 307 is squeezed and matched with the tie strip 305.
[0038] When the tie strip 305 is squeezed and stretched outward, it pulls the first conical cover 302 and the second conical cover 303 closer together, so that the barrier ring 301 at the center is squeezed inward, forming a sealed barrier area outside the water pipe 1;
[0039] In the above, reference Figure 3 As shown, after the two water pipes are butt-jointed, a locking structure is used to fix the whole, and then under the action of the anti-seepage member 3, a sealed barrier area is formed at the joint between the butt-jointing device and the water pipe member 1. For a specific description, refer to the following:
[0040] First, regarding the locking structure, the locking structure includes a convex plate 203, a first cross bar 204, a second cross bar 205, a connecting rod 206, an external thread 207 and a bolt 208. The convex plate 203 is symmetrically fixed on the hoop 201, and the first cross bar 204 and the second cross bar 205 are both fixed in the convex plate 203. The first cross bar 204 is fixedly connected to the connecting rod 206, and the connecting rod 206 is slidably inserted relative to the second cross bar 205. The connecting rod 206 extends out of the second cross bar 205 and is provided with an external thread 207. The bolt 208 is matched with the external thread 207. After the water pipe fitting 1 is docked, the connecting rod 206 is inserted into the second cross bar 205, and then the bolt 208 is tightened relative to the external thread 207 on the connecting rod 206 until the bolt 208 is squeezed and contacted with the first cross bar 204. Therefore, under the limiting action of the bolt 208, the hoop 201 is kept surrounded and pressed from the outside on the water pipe fitting 1, forming a locking effect.
[0041] Next, regarding the adaptability to the caliber of the water pipe fitting 1, since the interface of the hoop 201 used has a notch 202 on one side, and the hoop 201 itself is made of an elastic stainless steel sheet, the size of the space enclosed by the hoop 201 will change as the ends of the notch 202 move relatively closer or farther away, thereby making it adaptable to the fastening and docking of water pipe fittings 1 of different calibers.
[0042] Next, for the anti-seepage effect, refer to Figure 6 As shown, after the docking is completed, since the anti-seepage component 3 also includes a limiting sleeve 308, a locking pin 309 and a spring 3010, the limiting sleeve 308 is fixed on the tie strip 305, and the locking pin 309 is rotatably installed on the top of the top rod 307. The locking pin 309 is engaged with the limiting sleeve 308. One end of the spring 3010 is fixedly connected to the top rod 307, and the other end is fixed in the sleeve 306. The limiting sleeve 308, the locking pin 309 and the spring 3010 constitute a structure for ejecting the tie strip 305. Figure 8 When the locking pin 309 and the limiting sleeve 308 are in the engaged state as shown in the figure, under the action of the spring 3010 expanding outward, the restraining strip 305 is squeezed and stretched outward, pulling the first conical cover 302 and the second conical cover 303 relatively close to each other, so that the blocking ring 301 at the center is squeezed inward to form a sealed blocking area outside the water pipe fitting 1. The blocking area is in the shape of a drum, and the first conical cover 302 and the second conical cover 303 are pressed and fitted against the water pipe fitting 1, so that the existing joints can be further sealed comprehensively and effectively.
[0043] As for the anti-seepage effect, further, a lining 21 is fixedly sleeved in the hoop 201, and the lining 21 is in a circular ring shape. When the water pipe fitting 1 is operated, the lining 21 is tightened with the hoop 201 and is tightly attached to the water pipe fitting 1. A barrier strip 211 is symmetrically fixed in the lining 21, and the barrier strip 211 is in a circular ring shape and protrudes relative to the inner wall of the lining 21. The lining 21 is made of polyvinyl chloride membrane material. The design of the lining 21 forms a multi-layer structure on the surrounding body connected to the water pipe fitting 1, and is prepared using relevant hydrophobic materials. Certain supplements are also made in the structural modeling (the barrier strip 211 mentioned above forms another barrier surface). Combined with the above improvements, the overall anti-leakage effect of the device is significantly improved and enhanced.
[0044] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
