DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] By providing a local repair device for a pipeline stainless steel double expansion ring in an embodiment of the present application, the problem is solved that for some pipeline interface positions or positions where cracks occur, if direct excavation repair is carried out, this repair method is likely to cause traffic jams, and the operation is cumbersome, time-consuming and laborious, resulting in a contradiction between pipeline repair and obstruction of urban traffic.
[0022] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.
[0023] An embodiment of the present utility model discloses a local repair device for a pipeline stainless steel double expansion ring. As shown in the attached Figures 1-3 figure, it includes a water-stop rubber strip 2 arranged inside a pipeline 1 to be repaired, and a stainless steel double expansion ring 3 is movably clamped outside the water-stop rubber strip 2;
[0024] The stainless steel double expansion ring 3 is provided with a notch, and T-shaped blocks 4 are fixedly connected to the notch positions of the stainless steel double expansion ring 3;
[0025] A fixing plug 5 is movably clamped at the notch position of the stainless steel double expansion ring 3, and the fixing plug 5 is located between two groups of T-shaped blocks 4.
[0026] Further, the water-stop rubber strip 2 is provided with an embedding groove 201 corresponding to the positions of the stainless steel double expansion ring 3 and the fixing plug 5. The provided embedding groove 201 facilitates providing clamping and limiting for the stainless steel double expansion ring 3, enabling the installation position of the stainless steel double expansion ring 3 on the water-stop rubber strip 2 to be quickly docked, and at the same time, the stainless steel double expansion ring 3 is limited after clamping.
[0027] Furthermore, the water-stop rubber strip 2 is provided with a water-stop groove 202. Through the design of the water-stop rubber strip 2 and the pipeline 1 to be repaired with the water-stop groove 202, a good water-stop and waterproof effect is achieved at the interface position.
[0028] The T-shaped block 4 is provided with a first threaded hole 401 for fixing the position of the fixing plug 5, and the fixing plug 5 is provided with a second threaded hole 502 corresponding to the position of the first threaded hole 401. Through the design of the first threaded hole 401 and the second threaded hole 502, it is convenient to realize the internal penetration of bolts for reinforcement between the T-shaped block 4 and the fixing plug 5.
[0029] Furthermore, a wedge-shaped groove 501 is formed in the fixed plug 5. The provided wedge-shaped groove 501 enables the fixed plug 5 to generate a thrust on the T-shaped block 4 when the fixed plug 5 is inserted into the notch of the stainless steel double-expansion ring 3, so that the T-shaped block 4 drives the stainless steel double-expansion ring 3 to expand and tighten, ensuring that the water-stop rubber strip 2 is closely attached to the pipeline 1 to be repaired, and the sealing effect is good.
[0030] When repairing the pipeline 1 to be repaired with this pipeline stainless steel double-expansion ring partial repair device, first place the water-stop rubber strip 2 at the repair position of the pipeline 1 to be repaired, then align and snap the stainless steel double-expansion ring 3 into the inner part of the embedding groove 201. Subsequently, snap the fixed plug 5 between the two T-shaped blocks 4, and horizontally push the fixed plug 5 to expand and tighten the stainless steel double-expansion ring 3, so that the stainless steel double-expansion ring 3 applies a clamping force to the water-stop rubber strip 2, making the water-stop rubber strip 2 closely fit the inner wall of the pipeline 1 to be repaired to form a seal, and then complete the repair of the pipeline 1 to be repaired.
[0031] This repair device is convenient for locally repairing the interior of the pipeline 1 to be repaired without the need for excavation repair. Through the expansion and tightening effect of the stainless steel double-expansion ring 3, the T-shaped block 4 and the fixed plug 5 on the water-stop rubber strip 2, the water-stop rubber strip 2 is closely attached and sealed to the pipeline 1 to be repaired, thus ensuring a good repair effect on the leaking position of the pipeline 1 to be repaired. This repair device is simple to operate, time-saving and labor-saving, and will not cause traffic problems caused by urban excavation, meeting the use requirements.
[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
