[0002] Water pipeline is a kind of pipeline system for conveying water resources, and such pipeline system is widely applied in city water supply, irrigation, drainage and sewage treatment and other fields, and water pipeline is usually made of various materials, such as metal, plastic, concrete or glass fiber, to convey water resources from water source to the place needed, or discharge waste water to sewage treatment facility, and pipeline support is a device for supporting and fixing pipeline, which helps the installation and maintenance of pipeline system and can be used to support various types and sizes of pipeline.

[0003] Through the search of Chinese utility model patent (publication number CN221780145U), a kind of water conservancy project pipeline support is disclosed, including support base plate, arc clamping plate, vertical slot, U-shaped insert limiting plate, screw rod, handle, top plate, can be inserted into land by the setting of vertical insert rod, and drive multiple sharp corner insert plate transversely, improve the stability of support installation.

[0004] But through practical application, it is found that the technical scheme still has at least the following defects:

[0005] Pipeline material usually has thermal expansion coefficient, when environmental temperature or fluid temperature in pipe changes, the degree of thermal motion of pipe molecules will change accordingly. When temperature rises, molecular motion intensifies, and the distance between molecules increases, resulting in the increase of pipe length and volume;When temperature decreases, molecular motion slows down, and the distance between molecules decreases, and the length and volume of pipe also decrease. Resulting in the expansion or contraction of the pipe in the radial direction, the diameter of the pipe changes. When the pipe is fixed on the support, it cannot freely stretch and shrink, and stress will be generated inside the pipe. Long-term stress concentration may cause fatigue cracks in pipe material, reduce the service life of the pipe, and even cause pipe rupture, causing water conservancy engineering accident.

[0013] Preferably, the base is connected with a ground nail.

[0014] Compared with the prior art, the technical scheme has the following beneficial effects:

[0015] (1) The utility model discloses a pivot, spring, connecting block and sliding slot are arranged, so that the pressure plate can have a certain elastic expansion space when the pipeline expands or shrinks due to heat. When the pipeline expands due to heat, the spring is compressed, and the pressure plate can move appropriately with the expansion of the pipeline, so that the pipeline is not subjected to excessive constraint force, and stress concentration caused by the expansion of the pipeline being hindered is avoided. When the pipeline shrinks due to cold, the spring is elongated, and the pressure plate moves with the pipeline, so that the pipeline is always closely attached to the outer wall of the pipeline, and the expansion and contraction deformation of the pipeline is effectively compensated. The pressure plate can uniformly transmit pressure to the outer wall of the pipeline, so that local excessive pressure does not damage the pipeline. When the pipeline is subjected to external impact, such as sudden change of water flow, collision of objects, etc., the structure composed of the spring and the pressure plate can absorb and disperse part of the impact energy, so that the direct impact of the impact on the pipeline is reduced, and the integrity of the pipeline is protected.

[0016] (2) By setting the guide plate, when installing the pipeline provides a clear path for the pipeline, can make the pipeline along the guide plate into two groups of pressing plate between, avoid manual adjustment of the position of the pressing plate, save the installation time, improve the overall installation progress.

[0017] (3) By setting the sponge pad, can the pressure of the pressing plate on the pipeline evenly dispersed, prevent the pressure concentrated in the local area of the pipeline, thus avoiding the pipeline due to local stress too large and produce deformation, rupture and other problems, guarantee the structural integrity of the pipeline. Sponge pad can compensate for the size error between the pressing plate and the pipeline through its elastic deformation, so that the pressing plate can better fix and protect the pipeline, ensure the quality of pipeline installation.

[0018] (4) By setting the non-slip mat, increase the friction coefficient between the pipeline and the placing groove, make the pipeline keep stable in the placing groove, prevent the pipeline from sliding, ensure the accuracy of the pipeline position.

[0019] (5) By setting the connecting plate, pressing block, sliding block and spring, can install the pipeline at the same time, the fixed nail is inserted into the side of the installation surface, without the need to install the pipeline after the separate insertion operation of the fixed nail, reduce the construction steps, save the installation time, improve the overall construction efficiency, enhance the connection strength between the pipeline and the installation surface, make the pipeline more not easy to appear loose, displacement and other situations in the use process.

[0020] (6) By setting the ground nail, provide a more solid support for the pipeline support, effectively resist the horizontal force, prevent the support from horizontal displacement or shaking, ensure the stable operation of the pipeline system. BRIEF DESCRIPTION OF DRAWINGS

By rotating the handle 9, the threaded rod 8 is rotated, since the threaded rod 8 is threadedly connected with the top wall of the fixed frame 4, the rotation of the threaded rod 8 will make it move downward, thereby pushing the fixed block 7 and the clamping plate 5 connected therewith to move downward. The clamping plate 5 is an arc-shaped plate, which is matched with the arc-shaped pipeline placed in the placing groove 2 of the base 1, and can preliminarily fix the pipeline from above. The bottom wall of the clamping plate 5 is provided with two groups of installation grooves 10, and the two groups of installation grooves 10 are symmetrically arranged. The clamping plate 5 is rotatably connected with a rotating shaft 11, and the rotating shaft 11 is located in the installation groove 10. The rotating shaft 11 is connected with a pressing plate 12, the installation groove 10 cooperates with the pressing plate 12, the clamping plate 5 is provided with a hidden groove 14, and the hidden groove 14 is communicated with the installation groove 10. The inner wall of the hidden groove 14 is connected with a spring 16, the other end of the spring 16 is connected with a connecting block 17, the outer side wall of the pressing plate 12 is provided with a sliding groove 13, the connecting block 17 is slidably connected with the sliding groove 13, and the cross section of the connecting block 17 and the sliding groove 13 is convex. The inner side wall of the pressing plate 12 is connected with a sponge pad 23. The bottom end of the pressing plate 12 is connected with a guide plate 3. When the clamping plate 5 moves downward and approaches the pipeline, with the clamping plate 5 continuing to drop, the outer wall of the pipeline will enter between the two groups of pressing plates 12 along the direction of the guide plate 3. The outer wall of the pipeline will push the pressing plate 12 to rotate around the rotating shaft 11, so that the pressing plate 12 gradually adheres to the outer wall of the pipeline. In this process, the spring 16 in the hidden groove 14 applies an outward pushing force to the pressing plate 12 through the connecting block 17, the connecting block 17 slides in the sliding groove 13, and the pressing plate 12 is always tightly adhered to the outer wall of the pipeline.

With the downward movement of the connecting plate 15, the pressing block 21 pushes the sliding block 20 to slide horizontally in the driving groove 27. During the sliding process of the sliding block 20, the spring 26 is compressed, and at the same time, the fixing nails 19 connected to the vertical surface of the sliding block 20 gradually penetrate out of the insertion holes 25 and are inserted into the installation surface on the side.

[0026] The specific implementation process is as follows:
