AI Technical Summary
The existing water conservancy project pipeline protective cover is prone to water leakage at the connection, which leads to overflow of the water connection tank, causing the ground to collapse or collapse. The gravity of the water tank and water may cause the pipeline to shift, increasing the risk of damage or looseness at the connection.
A water conservancy engineering pipeline protective cover is designed, and the lower clamp and the upper clamp are fixed to the outside of the flange through the connecting assembly, and a diversion pipe extends to the underground flow tube at the bottom of the lower clamp. There are multiple water outlets at the bottom of the diversion pipe to divert water to the ground to avoid affecting the ground.
Through the fixing of the lower clamp and the upper clamp, the stability of the flange connection is enhanced, and the diversion pipe effectively diverts water leakage, avoiding the impact of water on the ground around the pipeline, and reducing the risk of damage or loosening at the connection.

Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pipeline protection, and in particular to a pipeline protection cover for a water conservancy project. Background Art
[0002] In water conservancy projects, the pipeline system is a key facility for transporting water, and its stable operation is crucial to the safety and efficiency of the entire project.
[0003] A Chinese patent discloses a protective cover for a water conservancy project pipeline, with authorization announcement number CN212616899U. The above patent includes a first pipe body and a second pipe body, the first pipe body and the second pipe body are connected by a flange, and a limiting clamp is provided on the first pipe body and the second pipe body, the two limiting clamps are arranged opposite to each other, and two locking bolts are passed through the two limiting clamps, and the protruding ends of the locking bolts are threadedly connected with nuts, and the inner top surfaces of the two limiting clamps are fixed with extrusion plates that abut against the side surfaces of the flanges, and the lower inner walls of the two limiting clamps are fixed with extrusion rods that abut against the side surfaces of the flanges, and a water receiving box located directly below the flange is clamped between the lower ends of the two limiting clamps. Although the above patent can further enhance the connectivity of the connection between the two pipe bodies under the action of the two limiting clamps to prevent the loosening of the connection between the pipe bodies, a water receiving box is added at the same time to facilitate the collection of water flowing down from the connection to prevent it from spreading everywhere. However, the water tank can only be used for storage. If the connection leaks and the water tank is not found in time for cleaning, the water overflowing from the water tank will damage the surrounding ground, causing dents, collapses and other safety hazards. In addition, the gravity of the water tank and water acts on the flange connection. The downward pulling force may cause the pipe to deviate at the flange connection and destroy the centering of the pipe, thereby aggravating the damage or loosening of the connection. Therefore, those skilled in the art provide a water conservancy project pipe protective cover to solve the problems raised in the above background technology. Utility Model Content

[0028] Reference Figure 1 , Figure 3 and Figure 4The embodiment of the present application provides a water conservancy project pipeline protection cover, including two flanges 1 for connecting pipelines, and upper and lower ends of the outer sides of the two flanges 1 are respectively installed with upper clamps 3 and lower clamps 2, and the two are tightly fixed to the outer sides of the flanges 1 through two symmetrically arranged connecting components. The inner side of the bottom of the lower clamp 2 is equipped with a downwardly extending guide pipe 5, and a plurality of water outlets 6 are arranged around the bottom of the guide pipe 5. Specifically, the lower clamp 2 and the upper clamp 3 are installed on the outer side of the flange 1 through the connecting component. Under the fixing action of the lower clamp 2 and the upper clamp 3, the flange 1 can be protected. At the same time, the closed structure formed by the lower clamp 2 and the upper clamp 3 on the outer side of the flange 1 ensures the stability of the connection of the flange 1, and a guide pipe 5 extending to the bottom of the lower clamp 2 is arranged at the bottom of the lower clamp 2. When the connection of the flange 1 is loose or the sealing is poor and leakage occurs, the guide pipe 5 can guide the leaked water to the ground to avoid the influence of water leakage on the ground around the pipeline.
[0029] Reference Figure 1 , Figure 2 and Figure 3 The connection assembly is composed of two connecting rods 8 fixedly connected to the top of the lower clamp 2, a fixing plate 9 fixed to the outside of the upper clamp 3, and two positioning plates 10 attached to the top of the fixing plate 9. The tops of the two connecting rods 8 are both provided with threads, and they pass through the interior of the upper clamp 3 and the fixing plate 9 in turn, and are threadedly connected with the corresponding positioning plates 10. Specifically, when the upper clamp 3 is installed on the top of the flange 1, the top of the connecting rod 8 extends to the top of the fixing plate 9, and the positioning plate 10 is rotated to screw with the top of the connecting rod 8, so that the connection operation of the upper clamp 3 and the lower clamp 2 can be completed, so that it can be stably installed on the outside of the flange 1, and the installation work is simple and convenient.
[0030] Reference Figure 1 , Figure 3 and Figure 4 At the bottom of the guide pipe 5, a baffle 7 is fixedly connected to one side close to the water outlet 6. A certain distance is maintained between the inner side of the baffle 7 and the water outlet 6. The baffle 7 is arranged on the outer side of the water outlet 6 to prevent the water outlet 6 from being blocked by soil when the guide pipe 5 is inserted into the ground. The distance between the baffle 7 and the water outlet 6 can ensure the normal water discharge operation of the water outlet 6.
[0031] Reference Figure 1 and Figure 3 The bottom of the lower clamp 2 is fixedly connected with a support plate 4. The support plate 4 with a larger bottom support area can better support the lower clamp 2. Two plug rods 11 are symmetrically fixedly connected to the bottom of the support plate 4. The plug rods 11 are inserted into the ground to enhance the stability of the support plate 4, so as to improve the supporting effect of the support plate 4 and the pipeline.

[0033] Working principle:
[0034] When the upper clamp 3 is installed on the top of the flange 1, the top of the connecting rod 8 extends to the top of the fixing plate 9, and the positioning plate 10 is rotated to be screwed with the top of the connecting rod 8, so that the upper clamp 3 and the lower clamp 2 can be connected to each other stably, and the installation work is simple and convenient. While the flange 1 can be protected under the fixing action of the lower clamp 2 and the upper clamp 3, the closed structure formed by the lower clamp 2 and the upper clamp 3 on the outside of the flange 1 ensures the stability of the connection of the flange 1, and a guide pipe 5 extending to the bottom of the lower clamp 2 is provided at the bottom of the lower clamp 2. When the connection of the flange 1 is loose or the seal is poor and leakage occurs, the guide pipe 5 can guide the leaked water to the underground to avoid the influence of water leakage on the ground around the pipeline.
