All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: Refer to Figures 1 to 4 A water conservancy pipeline connection device for water conservancy projects, including a base 1;

[0026] Two auxiliary connection mechanisms are provided. The auxiliary connection mechanisms include a similar component 2 and an auxiliary connection component 3. The similar component 2 includes a mounting groove 21 opened on the upper surface of the base 1. Two first guide rods 22 are fixedly connected to the inner wall of the mounting groove 21. A movable seat 23 is slidably sleeved on the two first guide rods 22. Two springs 24 are fixedly connected between the side wall of the movable seat 23 and the inner wall of the mounting groove 21. Multiple springs 24 are respectively sleeved on multiple first guide rods 22. The bottom surface of the movable seat 23 is in contact with the inner bottom surface of the mounting groove 21.

[0027] The auxiliary connection assembly 3 includes a support column 31 fixedly connected to the upper surface of the movable seat 23. A bidirectional threaded rod 32 is provided above the movable seat 23. The bidirectional threaded rod 32 is rotatably connected to the side wall of the support column 31 through a bearing. An arc-shaped support plate 33 is fixedly connected to the top of the support column 31. Two arc-shaped clamping plates 34 are provided inside the arc-shaped support plate 33. A second guide rod 35 is fixedly connected to the side wall of the two arc-shaped clamping plates 34 that are far apart. The two second guide rods 35 are slidably connected to the side wall of the arc-shaped support plate 33. Nuts 36 are threadedly connected to the threaded sections of the bidirectional threaded rod 32 with opposite thread directions. A connecting rod 37 is fixedly connected to the upper surface of the two nuts 36. The side ends of the two second guide rods 35 are... The two connecting rods 37 are fixedly connected to the side walls. The two nuts 36 are equidistant from the support column 31. The inner wall of the arc-shaped clamp 34 is provided with multiple strip grooves 38. Rollers 39 are rotatably connected in each of the multiple strip grooves 38. After the pipe to be connected is fixed, it can still be rotated and adjusted through the multiple rollers 39. The two bidirectional threaded rods 32 are fixedly connected to the side ends with knobs for easy adjustment by the staff. Multiple second guide rods 35 are horizontally set. The two auxiliary connecting mechanisms are symmetrically set about the vertical bisection of the base 1. This design allows the two fixed pipes to be connected to move closer to each other under the tension of the two springs 24, making the pipe connection operation easier.

[0028] The working principle of this utility model is as follows: Place the base 1 in a suitable position, and place one end of each of the two water pipes to be connected into the arc-shaped support plates 33 of the two auxiliary connecting mechanisms. By rotating the knob on the bidirectional threaded rod 32, the bidirectional threaded rod 32 is rotated, which drives the two nuts 36 to move on the bidirectional threaded rod 32. The movement of the nuts 36 drives the two arc-shaped clamping plates 34 to move closer to each other through the connecting rod 37, gradually clamping the pipes. The two nuts 36 move synchronously. Therefore, after the pipes to be connected are fixed, the pipes will be in the center position of the arc-shaped support plate 33, which can quickly guide the pipes to achieve initial positioning. Due to the rollers 39 on the inner wall of the arc-shaped clamping plate 34, the wear on the pipes can be reduced during the clamping process, and the pipes can be easily fine-tuned. After the pipes on both sides are fixed, the connection points of the two pipes will automatically fit together under the action of the springs 24 of their respective auxiliary connecting mechanisms, which makes the connection easier. When it is necessary to align the connection holes of the two pipes, simply rotate the pipes to be adjusted. The construction efficiency is greatly improved, saving a lot of construction time.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
