Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower technology, specifically to a water conservancy and hydropower construction pipeline connection device. Background Technology

[0002] Hydropower is a comprehensive project that utilizes water energy resources for power generation, flood control, irrigation, water supply, navigation, and water environment management. Hydropower projects are an important part of national infrastructure. Through scientific planning and meticulous construction, hydropower projects can effectively regulate water resource allocation and alleviate water shortages. Pipelines are crucial in hydropower construction projects, serving to support, fix, guide, waterproof, conduct water, and connect equipment and pipelines to ensure smooth fluid transport and distribution. Due to the limited length of pipelines, they need to be connected to extend their length.

[0003] A search revealed an existing technology (publication number: CN212004661U) for a pipe connection device, which states that it "includes a socket pipe into which at least one external pipe can be inserted, a sealing device is provided between the socket pipe and the external pipe, a fixed sleeve is fixedly fitted on the socket pipe to resist the external pipe, and a first half-ring and a second half-ring are hinged on the fixed sleeve to prevent the external pipe from detaching from the socket pipe, and the first half-ring and the second half-ring can be opened and closed and locked onto the fixed sleeve by a locking device." However, the existing technology cannot support the pipe. In water conservancy and hydropower projects, the water flow rate in the pipe is large, which will generate vibration, and the weight of the pipe itself and the water flow is large. Long-term use can easily lead to loosening of the connection, affecting the connection effect. Therefore, it is necessary to design a pipe connection device for water conservancy and hydropower construction. Utility Model Content

[0004] The purpose of this utility model is to provide a pipeline connection device for water conservancy and hydropower construction, which solves the problem in related technologies that the pipeline cannot be supported during use. Due to the large flow rate of water in the pipeline in water conservancy and hydropower projects, vibration will occur, and the weight of the pipeline itself and the water flow is large, which can easily lead to loosening of the connection after long-term use.

[0005] The technical solution of this utility model is as follows:

[0006] A water conservancy and hydropower construction pipeline connection device includes a connecting seat. A pair of sliding grooves are provided on the top end face of the connecting seat. Two movable frames are provided on the top of the connecting seat, and the bottom of the movable frames is slidably connected to the sliding grooves. Lifting ports are provided on both sides of the movable frames, and sliders are slidably installed inside the lifting ports. A first lifting ring is installed on the top of the slider via a rotating shaft. A first screw is threaded onto the top of the lifting port, and a second lifting ring is welded to one end of the first screw. The second lifting ring is connected to the first lifting ring. A telescopic port is provided in the center of the slider, and an internally threaded pipe is welded to one end of the telescopic port. A support rod is inserted into the telescopic port, and one end of the support rod is bent upwards and welded with a clamp. A second screw is threaded onto the inside of the internally threaded pipe.

[0007] Preferably, the support rod is made of magnet, one end of the second screw is magnetically connected to the other end of the support rod, the clamp is arc-shaped, and the inner wall of the clamp is glued with a rubber pad.

[0008] Preferably, vertical plates are welded to both ends of the top of the connecting seat, and support plates are welded to both sides of the top of the vertical plates. An electric telescopic rod is screwed onto the support plate, and the telescopic end of the electric telescopic rod is screwed and fixed to the outer wall of the movable frame.

[0009] Preferably, the outer walls of both ends of the connecting seat are screwed with a support plate, and a power supply is placed on the top of the support plate. The power supply is equipped with a connecting wire, which is connected to the electric telescopic rod.

[0010] Preferably, positioning plates are welded to both outer walls of the connecting seat, and screw holes are provided on the positioning plates.

[0011] Preferably, a handwheel is welded to one end of the top of the first screw.

[0012] Preferably, the connector is made of alloy steel, and the bottom of the connector is coated with an anti-corrosion coating.

[0013] Preferably, the other end of the support rod is fitted with the inner wall of the telescopic port, and the diameter of the telescopic port is the same as the diameter of the internally threaded pipe.

[0014] The beneficial effects of this utility model are:

[0015] By connecting two pipes used in water conservancy and hydropower construction, the first screw is moved up and down by turning it. The first and second lifting rings can drive the slider to move up and down synchronously in the lifting port during the lifting process of the first screw. When the clamping plate is flush with the pipe, turning the second screw can push the support rod forward and use the clamping plate to hold and fix the pipe, which can provide a good support effect, thereby reducing the vibration generated when water flows in the pipe and avoiding the connection from loosening under long-term use, which would affect the connection effect.

Lifting ports 4 are provided on both sides of the movable frames 3, and sliders 5 are slidably installed inside the lifting ports 4. A first lifting ring 6 is installed on the top of the slider 5 through a rotating shaft. A first screw 7 is threadedly installed on the top of the lifting port 4, and a second lifting ring 8 is welded to one end of the bottom of the first screw 7. The second lifting ring 8 is connected to the first screw 7. A series of lifting rings 6 are interconnected. A telescopic opening 9 is provided in the center of the slider 5, and an internally threaded tube 10 is welded to one end of the telescopic opening 9. A support rod 11 is inserted into the telescopic opening 9, and one end of the support rod 11 is bent upward and welded with a clamping plate 13. A second screw 12 is installed inside the internally threaded tube 10 through threads. The support rod 11 is made of magnet, and one end of the second screw 12 is magnetically connected to the other end of the support rod 11. The clamping plate 13 is arc-shaped, and a rubber pad 14 is glued to the inner wall of the clamping plate 13. The rubber pad 14 can increase the friction between the clamping plate 13 and the pipe. For friction, vertical plates 15 are welded to both ends of the top of the connecting seat 1, and support plates 16 are welded to both sides of the top of the vertical plates 15. An electric telescopic rod 17 is screwed onto the support plate 16, and the telescopic end of the electric telescopic rod 17 is screwed to the outer wall of the movable frame 3. The movable frame 3 can be moved on the slide groove 2 by the electric telescopic rod 17. Support plates 18 are screwed to the outer walls of both ends of the connecting seat 1, and a power supply 19 is placed on the top of the support plate 18. The power supply 19 is equipped with a connecting wire 20, and the connecting wire 20 is connected to the electric telescopic rod 17. The power supply 19 can be supported by the support plate 18. 9.
