Description

Technical Field

[0001] This utility model belongs to the technical field of water conservancy engineering equipment, specifically a water pipe connection device for water conservancy projects. Background Technology

[0002] During the construction of water conservancy projects, it is often necessary to connect multiple sections of water pipes to transport water resources. Currently used pipe connection devices have several problems that urgently need to be addressed: First, their sealing performance is poor, and leaks easily occur at the joints due to loose fit, affecting the normal operation of the water conservancy project; second, the connection stability is insufficient, and the joints are prone to loosening under water flow impact or external pressure, making it difficult to maintain a long-term reliable connection; third, the installation process is relatively cumbersome, requiring multiple people to coordinate and adjust the positioning, which negatively impacts construction efficiency. Summary of the Invention

[0003] To address the problems existing in the background technology, this utility model provides a water pipe connection device for water conservancy projects.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a water pipe connection device for water conservancy projects, comprising a U-shaped plate, a bidirectional screw, a sliding rod, two base mechanisms, two top-supporting mechanisms, three fixing plates, and three threaded rods;

[0005] The U-shaped plate has its open end facing downwards. A bidirectional screw and a sliding rod are located at the lower end of the U-shaped plate. One end of the bidirectional screw is rotatably connected to the inner wall of one end of the U-shaped plate, and the other end of the bidirectional screw rotatably passes through the inner wall of the other end of the U-shaped plate. Both ends of the sliding rod are fixedly connected to the two inner walls of the U-shaped plate, and the sliding rod is parallel to the bidirectional screw. Two base mechanisms are provided on the bidirectional screw and the sliding rod, and the two base mechanisms are symmetrically arranged. Each base mechanism has a corresponding top-supporting mechanism above it, and both top-supporting mechanisms are located on the U-shaped plate. Fixed plates are provided on the upper end and both sides of the outer wall of the U-shaped plate. Each fixed plate has a threaded hole, and each threaded hole is threadedly connected to a corresponding threaded rod.

[0006] Each of the base mechanisms includes a slider, an arc plate, and a rubber pad;

[0007] The slider is provided with a second threaded hole and a sliding hole. The second threaded hole is threadedly connected to a bidirectional screw, and the sliding hole is slidably connected to a first sliding rod. The upper end of the slider is fixedly connected to a first arc plate, and the inner wall of the first arc plate is fixedly connected to a first rubber pad.

[0008] Each of the aforementioned abutment mechanisms includes a spring, a second slide rod, a second arc-shaped plate, a second rubber pad, and an arc-shaped limiting plate;

[0009] The second sliding rod slides through the side wall of the U-shaped plate. One end of the second sliding rod is fixedly connected to the second arc-shaped plate, which is fixedly connected to the second rubber pad. The other end of the second sliding rod is fixedly connected to the arc-shaped limiting plate, which works in conjunction with the outer wall of the U-shaped plate. The spring is fitted onto the second sliding rod, with one end fixedly connected to the second arc-shaped plate and the other end fixedly connected to the inner wall of the U-shaped plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Precise fixation to avoid offset: The two base mechanisms are driven by a bidirectional screw to move in opposite directions. The displacement of the two sliders is always equal, which can ensure that the water pipe axis is aligned with the center of the device, avoiding offset caused by unilateral force and providing a stable foundation for water pipe connection.

[0012] 2. Adaptive clamping to protect the pipe wall: The spring preload of the top clamping mechanism can be adaptively adjusted according to the diameter of the water pipe, and the preload is maintained within a reasonable range. This ensures effective clamping of water pipes of different diameters while avoiding damage to the pipe wall caused by rigid contact. The use of rubber pads increases friction to prevent the water pipe from sliding and further provides protection.

[0013] 3. Three-dimensional constraint to improve docking accuracy: The device uses a three-dimensional constraint structure of "lower support + upper tightening + side fixing" to eliminate the additional stress caused by relative displacement at the docking point of the two water pipes, ensuring that the docking surface is flat and fits well, which facilitates the use of various sealing methods and solves the problem of poor sealing caused by shaking when using traditional manual support.

[0014] 4. Easy to operate and reliable connection: The corresponding fixing plates of the two sets of devices are connected by a threaded rod, which is simple to operate. After tightening, a rigid connection can be achieved to ensure docking accuracy. The threaded rod can also be retained as a long-term reinforcement to further improve the impact resistance of the docking part.

[0015] 5. Stable structure and wide range of applications: The arc-shaped limiting plate in the top support mechanism can limit the maximum movement of the slide rod 2, preventing it from coming out of the U-shaped plate and ensuring the structural integrity of the top support mechanism in the non-working state; the device has good adaptability to water pipes of different diameters and has a wide range of applications.

[0016] In summary, this utility model, through its scientific and reasonable structural design, achieves precise and stable clamping of water pipes. It possesses numerous advantages, including adaptability to different pipe diameters, protection of pipe walls, improved docking accuracy and reliability, convenient operation, and structural stability. It effectively solves the problems existing in the traditional water pipe docking process and has high practical value in water pipe installation operations in water conservancy projects.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0021] This embodiment describes a water pipe connection device for water conservancy projects, including a U-shaped plate 1, a bidirectional screw 2, a slide bar 3, two base mechanisms, two top-supporting mechanisms, three fixing plates 12 and three threaded rods 13;

[0022] The U-shaped plate 1 has its open end facing downwards. The lower end of the U-shaped plate 1 is provided with a bidirectional screw 2 and a sliding rod 3. One end of the bidirectional screw 2 is rotatably connected to the inner wall of one end of the U-shaped plate 1, and the other end of the bidirectional screw 2 rotatably passes through the inner wall of the other end of the U-shaped plate 1. The two ends of the sliding rod 3 are respectively fixedly connected to the two inner walls of the U-shaped plate 1. The sliding rod 3 is arranged parallel to the bidirectional screw 2. The bidirectional screw 2 and the sliding rod 3 are provided with two base mechanisms. The two base mechanisms are symmetrically arranged. Each base mechanism is provided with a corresponding top support mechanism. Both top support mechanisms are provided on the U-shaped plate 1. The upper end and both sides of the outer wall of the U-shaped plate 1 are provided with fixing plates 12. Each fixing plate 12 is provided with a threaded hole, and each threaded hole is threadedly connected to a corresponding threaded rod 13.

[0023] Each of the base mechanisms includes a slider 4, an arc plate 5, and a rubber pad 6;

[0024] The slider 4 is provided with a threaded hole and a sliding hole. The threaded hole is threadedly connected to the bidirectional screw 2, and the sliding hole is slidably connected to the slide rod 3. The upper end of the slider 4 is fixedly connected to the arc plate 5, and the inner wall of the arc plate 5 is fixedly connected to the rubber pad 6.

[0025] Each of the aforementioned abutment mechanisms includes a spring 7, a slide bar 8, an arc-shaped plate 9, a rubber pad 10, and an arc-shaped limiting plate 11;

[0026] The second sliding rod 8 slides through the side wall of the U-shaped plate 1. One end of the second sliding rod 8 is fixedly connected to the second arc plate 9. The second arc plate 9 is fixedly connected to the second rubber pad 10. The other end of the second sliding rod 8 is fixedly connected to the arc-shaped limiting plate 11. The arc-shaped limiting plate 11 is used in conjunction with the outer wall of the U-shaped plate 1. The spring 7 is fitted on the second sliding rod 8. One end of the spring 7 is fixedly connected to the second arc plate 9. The other end of the spring 7 is fixedly connected to the inner wall of the U-shaped plate 1.

[0027] When the docking device is installed on the water pipe to be connected, the two base mechanisms and the two top support mechanisms form a clamping structure that works together from top to bottom. When the bidirectional screw 2 is rotated, its symmetrical thread will drive the two sliders 4 to move in opposite directions along the slide bar 3. Through the arc plate 5, the rubber pad 6 will be driven to symmetrically fit against the outer wall of the water pipe from below. Due to the synchronous adjustment characteristics of the bidirectional screw 2, the displacement of the two sliders 4 is always equal, which can ensure that the axis of the water pipe is consistent with the center of the device and avoid the offset caused by the force on one side.

[0028] Meanwhile, under the pre-tightening force of spring 7, the arc-shaped plate 29 of the top-supporting mechanism (spring 7 of the top-supporting mechanism needs to work within the effective elastic deformation range, its maximum compression and extension are matched with the appropriate pipe diameter range, the deformation can be adaptively adjusted with the water pipe diameter, and the pre-tightening force is maintained in the range of 50-300N: for small-diameter water pipes, the compression is small to avoid insufficient elasticity; for large-diameter water pipes, the extension is controllable to prevent squeezing the pipe wall, ensuring that the top-supporting force is always adapted to the pipe diameter), elastically presses the water pipe from above through rubber pad 210; when the device does not clamp water... When the pipe is in motion, the preload of spring 7 will push slide rod 8 into the U-shaped plate 1. At this time, the arc-shaped limiting plate 11 is in contact with the outer wall of the U-shaped plate 1, which can limit the maximum movement of slide rod 8 and prevent it from coming out of the U-shaped plate, thus ensuring the structural integrity of the top support mechanism in the non-working state. The elastic material of rubber pad 6 and rubber pad 10 increases friction to prevent the water pipe from sliding (rubber pad 6 and rubber pad 10 can be made of nitrile rubber with a Shore hardness of 60-80A, which has both wear resistance and elasticity), and avoids rigid contact that could damage the pipe wall.

[0029] After the two water pipes are fixed in the manner described above, three threaded rods 13 are used to connect the corresponding fixing plates 12 of the two sets of devices (the upper fixing plates 12 are aligned to achieve axial positioning, and the two side fixing plates 12 are aligned to limit radial offset). The threaded rods 13 are machined with continuous external threads, which match the threaded holes of the fixing plates 12. When connecting, first screw one end of the threaded rod 13 into the corresponding threaded hole of one of the devices and then out. After adjusting the positions of the two devices to align the pipe openings, screw the threaded rod 13 that has passed out into the corresponding threaded hole of the other device. After tightening, a rigid connection between the two sets of devices is achieved, ensuring docking accuracy.

[0030] During this process, the device uses a three-dimensional constraint structure of "lower support + upper tightening + side fixing" to eliminate additional stress (such as shear stress and bending stress) caused by relative displacement (such as misalignment and tilt) at the joint of the two water pipes, retaining only stable radial constraint stress, ensuring that the joint surface is flat and fits well. At this time, the joint surface is flat and fits well, which facilitates the use of sealing rings, welding or adhesives, solving the problem of poor sealing caused by shaking during traditional manual support. After sealing is completed, the threaded rod 13 can be retained as a long-term reinforcement to further improve the impact resistance of the joint.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
