They are corrosion-resistant, pressure-resistant, and have good sealing properties, and can ensure the safety and stable supply of water quality.

[0003] In a buried pipeline, two adjacent pipelines are usually fixed together by flange connection. The flange connection is sealed by bolt pre-tightening force to ensure that the liquid inside the pipeline will not leak.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A buried pipeline leakage protection mechanism in this embodiment includes a pipeline fixing seat 1 and two pipeline bodies 2. The pipeline fixing seat 1 is provided with a transverse fastening mechanism 3 and two longitudinal fastening mechanisms 4.

[0024] The connection between the two pipe bodies 2 is connected by a flange 201. Since the pipe will generate impact force in the return process of conveying liquid, leakage may occur if it only relies on the flange 201 for connection. Therefore, a transverse fastening mechanism 3 is provided to lock the left and right sides of the flange 201. The front and rear sides of the flange 201 are locked through the cooperation of the longitudinal fastening mechanism 4 and the fixing block 202, thereby improving the tightness of the connection between the two pipe bodies 2 and avoiding leakage.

[0025] The transverse fastening mechanism 3 includes a threaded hole 301. The middle part of the left and right sides of the pipe fixing seat 1 is provided with a threaded hole 301. The inside of the two threaded holes 301 is threadedly connected with a threaded rod 302. Two springs 303 are fixedly installed on the left and right inner walls of the pipe fixing seat 1, and a transverse fastening block 304 is fixedly installed between the opposite ends of each two springs 303.

[0026] When operating the transverse fastening mechanism 3 to lock the left and right sides of the flange 201, first rotate the two threaded rods 302, and the two threaded rods 302 move relative to each other in the threaded holes 301. The two threaded rods 302 drive the two transverse fastening blocks 304 to move relative to each other. Under the action of the spring 303, the movement of the transverse fastening blocks 304 is limited, so that the two threaded rods 302 are rotated to drive the two transverse fastening blocks 304 to move in opposite directions, thereby clamping the left and right sides of the flange 201 into the slots 305.

[0027] The two longitudinal fastening mechanisms 4 each include a slide groove 401, and the left and right inner walls of the pipe fixing seat 1 are provided with a slide groove 401. Slide blocks 402 are slidably installed inside the two slide grooves 401, and a main control rod 403 is rotatably installed on one side of the two slide blocks 402. The opposite ends of the two slide blocks 402 are fixedly installed with longitudinal fastening blocks 404.

[0028] There are two longitudinal fastening mechanisms 4, which cooperate with the two fixed blocks 202 on the two pipe bodies 2 respectively to achieve front and rear locking. During operation, the four main control rods 403 are first rotated, and the main control rods 403 drive the slider 402 to slide back and forth in the slide groove 401, and the slider 402 drives the longitudinal fastening block 404 to move back and forth to ensure that the longitudinal fastening block 404 and its corresponding fixed block 202 are tightly fitted. At this time, the locking holes 405 on the longitudinal fastening block 404 and the fixed block 202 coincide, and the bolts are inserted into the two locking holes 405 in turn to achieve locking between the two.

[0029] In order to improve the stability of the pipeline buried in the ground, extension plates are provided on the left and right sides of the pipeline fixing seat 1, and ground nails are provided inside the two extension plates. The ground nails are inserted into the ground to prevent the pipeline fixing seat 1 from being displaced due to the terrain environment, thereby improving the stability of the pipeline body 2 during installation.

[0030] When implementing, follow these steps:

[0031] 1) First, two pipeline bodies 2 are connected and fixed via flanges 201;

[0032] 2) Then, the flange 201 is located in the middle of the pipe fixing seat 1, and then the two threaded rods 302 are rotated to drive the two transverse fastening blocks 304 to move in opposite directions, and then the left and right sides of the flange 201 are inserted into the inside of the two slots 305, completing the locking of the left and right sides of the flange 201;

[0033] 3) Rotate the four main control rods 403 to drive the front and rear longitudinal fastening blocks 404 to move in opposite directions, so that the front two longitudinal fastening blocks 404 abut against the front side of the two fixing blocks 202 of one of the pipe bodies 2, and the rear two longitudinal fastening blocks 404 abut against the rear side of the other pipe body 2;

[0034] 4) Finally, the locking holes 405 on the four longitudinal fastening blocks 404 and the four fixing blocks 202 overlap, and bolts are inserted into the locking holes 405 to tightly fix each longitudinal fastening block 404 and the corresponding fixing block 202 together, so that the front and rear sides of the flange 201 will not loosen.

[0035] In summary, the buried pipeline leakage protection mechanism, by setting a transverse fastening mechanism 3, can realize the locking of the left and right sides of the flange 201 under the relative movement of the two transverse fastening blocks 304, and the left and right sides of the flange 201 are inserted into the corresponding slots 305; by setting two longitudinal fastening mechanisms 4, it can be supported on the two fixed blocks 202 of the two pipeline bodies 2 under the relative movement of the front and rear longitudinal fastening blocks 404, and the locking holes 405 on the fixed blocks 202 coincide with the locking holes 405 on the longitudinal fastening blocks 404. The front and rear locking of the flange 201 is realized by inserting bolts into the two overlapping locking holes 405.

[0036] Furthermore, by setting up a transverse fastening mechanism 3 and a longitudinal fastening mechanism 4, the left and right sides and the front and rear sides of the flange 201 are locked, and the flange 201 is fixed in all directions to ensure that it can withstand impact forces in all directions, thereby improving the sealing when the two pipe bodies 2 are connected and effectively preventing leakage problems caused by loose bolts.
