Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water conservancy pipeline connection device for water conservancy projects. Background Technology

[0002] Water conservancy projects are various projects built to regulate and utilize water resources, eliminate water hazards, and develop water resources. From the ancient Dujiangyan Irrigation System to the modern Three Gorges Project, they cover many aspects such as flood control, irrigation, power generation, and water supply, and are of great significance to economic and social development. Water pipelines are important components in water conservancy projects for transporting water. They come in various types, such as steel pipes and plastic pipes, and are selected according to different project needs. They can accurately transport water sources to designated locations, ensuring the efficient operation of irrigation, water supply, and other links. They are the key "veins" for water conservancy projects to realize water resource allocation and fulfill their functions.

[0003] Existing water conservancy pipelines mostly use welding and socket connections for joints. While these methods ensure the sealing of the pipeline joints, they also result in the inability to adjust the length and position of the pipes and joints. Due to measurement deviations, construction process issues, or limited equipment manufacturing precision, deviations between the actual installed dimensions and the design dimensions are inevitable. This can lead to difficulties in pipe alignment during actual installation, increasing installation difficulty and time costs. In some cases, forced installation can even cause pipe deformation or joint damage. Furthermore, when replacing partially damaged pipes later, the pipe joints at both ends cannot be retracted, making it difficult to remove the damaged pipes and install new ones.

[0004] Therefore, there is an urgent need to provide a water conservancy pipeline connection device for water conservancy projects to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a water conservancy pipeline connection device for water conservancy projects.

[0006] To solve the above-mentioned technical problems, the present invention provides a water conservancy pipeline connection device for water conservancy projects, including a protective pipe mechanism and a telescopic pipe mechanism. The protective pipe mechanism is slidably provided with a telescopic pipe mechanism for adjusting the length of the device, and the protective pipe mechanism is internally sealed with a corrugated pipe mechanism for ensuring the telescopic sealing of the device.

[0007] The telescopic tube mechanism is threadedly connected to a positioning mechanism.

[0008] One end of the protective pipe mechanism is bolted with a clamping mechanism for tightening the pipe joint.

[0009] The present invention is further configured such that: the protective tube mechanism includes a protective tube body, the protective tube body has two sliding grooves, the top and bottom ends of the protective tube body are provided with multiple positioning holes, one end of the protective tube body is integrally fixed with a socket, the socket is provided with multiple threaded holes, and a sealing gasket is also embedded in the inner side of the protective tube body.

[0010] Through the above technical solution, the protective pipe body can be made of metal or engineering plastic, which has good hardness and can play a good protective role for the internal structure. The inner and outer diameters of the socket are larger than the inner and outer diameters of the protective pipe body. When connecting the pipe, the pipe can be inserted from the socket. The threaded holes are arranged in an equidistant annular array. The sealing gasket can improve the sealing performance of the connection.

[0011] The present invention is further configured such that: the telescopic tube mechanism includes a telescopic tube body slidably disposed inside the protective tube body, and bolt slots are provided at both the top and bottom ends of the telescopic tube body.

[0012] With the above technical solution, the telescopic tube and the protective tube are made of the same material, and the outer diameter of the telescopic tube is slightly smaller than the inner diameter of the protective tube. The position of the bolt slot corresponds to the positioning hole.

[0013] The present invention is further configured such that: two sliding protrusions are integrally fixed on the protective tube body, and an insertion port is integrally fixed on one end of the protective tube body, and a sealing gasket is embedded and fixed on the insertion port.

[0014] Through the above technical solution, the sliding protrusion and the sliding groove are slidably connected, thereby limiting the telescopic tube body and preventing relative rotation between the telescopic tube body and the protective tube body. The spigot can be used to connect with the pipeline, and the sealing gasket can improve the sealing of the connection.

[0015] The present invention is further configured such that: the corrugated pipe mechanism includes a corrugated pipe body movably disposed inside the protective pipe body, a clamping ring is embedded in the inner side of one end of the corrugated pipe body, a sealing gasket is fitted to the outer side of one end of the corrugated pipe body, a fastening bolt is inserted through the clamping ring, and a sealing connection structure is fixed at the other end of the corrugated pipe body.

[0016] Through the above technical solution, the bellows body is telescopic, the clamping ring is made of metal, and the end of the fastening bolt is threaded to the inside of the socket. When the fastening bolt is tightened, the clamping ring will press one end of the bellows body against the socket. The sealing gasket can effectively improve the sealing performance at the pressing point. The sealing connection structure is the same as the above structure. The sealing connection structure seals the other end of the bellows body to the telescopic tube body. Therefore, when the telescopic tube mechanism slides along the protective tube mechanism, the bellows mechanism can always ensure the sealing performance of the device. When the device is buried underground, the protective tube mechanism can also prevent the bellows mechanism from being deformed by pressure.

[0017] The present invention is further configured such that: the positioning mechanism includes a positioning bolt threaded into a bolt slot, and an elastic washer is sleeved on the outside of the positioning bolt.

[0018] With the above technical solution, when the staff needs to adjust the length of the device, they can unscrew and remove the positioning bolts and slide the telescopic pipe mechanism to adjust it. When the specified length is reached, the staff can pass the positioning bolts through the bolt slots and screw them into the corresponding positioning holes to fix the telescopic pipe mechanism, thus completing the length adjustment of the device. This allows the device to compensate for errors generated during pipeline installation and provides a certain amount of expansion space when repairing or replacing pipelines, facilitating the installation of new pipelines into the water conservancy pipeline system. The elastic gasket can increase the thread friction between the positioning bolts and the bolt slots, preventing the positioning bolts from coming loose.

[0019] The present invention is further configured such that: the clamping mechanism includes a clamping bolt threaded into the threaded hole, a clamping ring is movably disposed on the clamping bolt, and a reinforcing rib is integrally fixed on the inner side of the clamping ring.

[0020] With the above technical solution, the inner diameter of the clamping ring is smaller than the inner diameter of the socket. When the device is connected to the pipeline, the operator can first remove the clamping bolts and the clamping ring, then insert the matching pipe joint into the socket, and put the clamping ring on the pipe from the other end of the pipe. Then tighten the clamping bolts to fix the clamping ring. At this time, the clamping ring will press the pipe joint, so that the pipe joint squeezes the sealing gasket, realizing the connection between the device and the pipeline. The reinforcing rib can effectively improve the strength of the clamping ring and ensure the uniformity of pressure. The other end of the device can also be connected to the pipeline in the same way.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This utility model, through the setting of a protective pipe mechanism, a telescopic pipe mechanism, a corrugated pipe mechanism and a positioning mechanism, enables the length of the device to be adjusted, thereby compensating for the length error generated during the installation of the pipeline system by adjusting its own length;

[0023] 2. By incorporating a protective pipe mechanism, a telescopic pipe mechanism, a corrugated pipe mechanism, and a positioning mechanism, this utility model allows for easy separation of the equipment to be repaired or replaced from the pipeline when workers need to replace a portion of the pipeline, or for smooth connection of new equipment to the pipeline system. This reduces the operational difficulty caused by fixed pipeline positions, improves maintenance efficiency, and lowers maintenance costs. Attached Figure Description

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] Please see Figures 1-6 A water conservancy pipeline connection device for water conservancy projects includes a protective pipe mechanism 1 and a telescopic pipe mechanism 2. The protective pipe mechanism 1 includes a protective pipe body 101 with two sliding grooves 102. Multiple positioning holes 103 are provided at both the top and bottom of the protective pipe body 101. A socket 104 is integrally fixed at one end of the protective pipe body 101, with multiple threaded holes 105. A sealing gasket 106 is also embedded on the inner side of the protective pipe body 101. The protective pipe body 101 can be made of metal or engineering plastic, with good hardness, providing good protection for the internal structure. The inner and outer diameters of the socket 104 are larger than the inner and outer diameters of the protective pipe body 101. When connecting the pipe, the pipe can be inserted through the socket 104. The threaded holes 105 are arranged in an equidistant annular array. The sealing gasket 106 improves the sealing performance of the connection.

[0033] like Figure 1 and Figure 3 As shown, a telescopic tube mechanism 2 for adjusting the length of the device is slidably arranged on the protective tube mechanism 1. The telescopic tube mechanism 2 includes a telescopic tube body 201 slidably arranged inside the protective tube body 101. Bolt slots 202 are opened at the top and bottom ends of the telescopic tube body 201. Two sliding protrusions 203 are integrally fixed on the protective tube body 101. A socket 204 is also integrally fixed at one end of the protective tube body 101. A sealing gasket 205 is embedded and fixed on the socket 204. The telescopic tube body 201 is made of the same material as the protective tube body 101, and the outer diameter of the telescopic tube body 201 is slightly smaller than the inner diameter of the protective tube body 101. The position of the bolt slots 202 corresponds to the positioning holes 103. The sliding protrusions 203 are slidably connected to the sliding grooves 102, thereby limiting the telescopic tube body 201 and preventing relative rotation between the telescopic tube body 201 and the protective tube body 101. The socket 204 can be used to connect with the pipeline, and the sealing gasket 205 can improve the sealing of the connection.

[0034] like Figure 1 , Figure 4 and Figure 5As shown, the protective tube mechanism 1 has an internal sealing connection with a bellows mechanism 3 to ensure the telescopic sealing of the device. The bellows mechanism 3 includes a bellows body 301 movably disposed inside the protective tube body 101. A compression ring 302 is embedded on the inner side of one end of the bellows body 301, and a sealing gasket 303 is fitted to the outer side of one end of the bellows body 301. A fastening bolt 304 is inserted through the compression ring 302. A sealing connection structure 305 is fixed to the other end of the bellows body 301. The bellows body 301 is telescopic. The clamping ring 302 is made of metal. The end of the fastening bolt 304 is threaded to the inside of the socket 104. When the fastening bolt 304 is tightened, the clamping ring 302 will press one end of the bellows body 301 against the socket 104. The sealing gasket 303 can effectively improve the sealing performance at the pressing point. The sealing connection structure 305 is the same as the above structure. The sealing connection structure 305 seals the other end of the bellows body 301 to the telescopic pipe body 201. Therefore, when the telescopic pipe mechanism 2 slides along the protective pipe mechanism 1, the bellows... The pipe mechanism 3 can always ensure the sealing of the device. When the device is buried underground, the protective pipe mechanism 1 can also prevent the corrugated pipe mechanism 3 from being deformed by pressure. The telescopic pipe mechanism 2 is threadedly connected to the positioning mechanism 4. The positioning mechanism 4 includes a positioning bolt 401 threaded into the bolt slot 202. An elastic washer 402 is sleeved on the outside of the positioning bolt 401. When the staff needs to adjust the length of the device, the positioning bolt 401 can be unscrewed and removed, and the telescopic pipe mechanism 2 can be slidably adjusted. When the specified length is reached, the staff can pass the positioning bolt 401 through the bolt slot 202 and screw it into the corresponding positioning hole 103 to fix the telescopic pipe mechanism 2, thus completing the length adjustment of the device. This allows the device to compensate for errors generated during pipeline installation and provides a certain amount of expansion space when repairing or replacing pipelines, making it easier to install new pipelines into the water conservancy pipeline system. The elastic washer 402 can increase the thread friction between the positioning bolt 401 and the bolt slot 202, preventing the positioning bolt 401 from unscrewing.

[0035] like Figure 1 and Figure 6As shown, one end of the protective pipe mechanism 1 is bolted with a clamping mechanism 5 for clamping the pipe joint. The clamping mechanism 5 includes a clamping bolt 501 threaded into the threaded hole 105. A clamping ring 502 is movably mounted on the clamping bolt 501. A reinforcing rib 503 is integrally fixed on the inner side of the clamping ring 502. The inner diameter of the clamping ring 502 is smaller than the inner diameter of the socket 104. When the device is connected to the pipeline, the operator can first remove the clamping bolt 501 and the clamping ring 502, then insert the joint of the matching pipe into the socket 104, and put the clamping ring 502 on the pipe from the other end of the pipe. Then tighten the clamping bolt 501 to fix the clamping ring 502. At this time, the clamping ring 502 will clamp the pipe joint, so that the pipe joint squeezes the sealing gasket 106, realizing the connection between the device and the pipe. The reinforcing rib 503 can effectively improve the strength of the clamping ring 502 and ensure the uniformity of pressure. The other end of the device can also be connected to the pipe in the same way.

[0036] When using this utility model, the operator can slide and adjust the length of the telescopic tube mechanism 2 and the protective tube mechanism 1, and fix them through the positioning mechanism 4. Then, the device is connected to the pipeline through the clamping mechanism 5. When the operator needs to maintain a part of the pipeline, the telescopic tube mechanism 2 can shorten the device, thereby facilitating the disassembly and replacement of the pipeline.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
