Description

Technical Field

[0001] The utility model relates to the technical field of pipeline insulation, in particular to an antifreeze and insulation device for rural water supply pipelines. Background Art

[0002] Rural water supply pipelines refer to the piping systems built to meet the needs of rural residents for both domestic and industrial purposes. These pipelines are typically installed underground, but some are exposed above ground for management and maintenance purposes. Water supply pipelines are prone to freezing in winter, resulting in water supply disruptions. Therefore, a pipe antifreeze and insulation device is required.

[0003] After searching, the Chinese patent "A winter water supply pipe antifreeze device" authorization announcement number is "CN217056848U". Through the use of fixed and disassembled components, it is convenient to protect the upper and lower insulation covers. Through the use of the first Velcro and the second Velcro, it is convenient to fix and disassemble the insulation cotton. Through the use of adjusting bolts, it is convenient to insulate pipes of different sizes.

[0004] The above application requires multiple rotations of the adjustment bolts during the process of fitting the pipe's thermal insulation cotton to the pipe, which is inconvenient to operate. At the same time, when rotating the bolts, the fitting status of the internal thermal insulation cotton and the pipe cannot be observed. When the bolts are rotated excessively, the thermal insulation cotton may be damaged, affecting the thermal insulation effect. When the bolts are rotated too little, the thermal insulation cotton may not fit the pipe well, which also affects the thermal insulation effect.

[0005] Therefore, a rural water supply pipeline antifreeze and heat preservation device is proposed to solve the above problems. Utility Model Content

[0011] Preferably, the inner bottom wall of the second cylinder is fixedly connected to a second spring, the top end of the second spring is fixedly connected to a second piston, and the second piston is slidably connected to the inner wall of the second cylinder to prevent the pressure in the first cylinder and the regulating tube from being too high.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] When implementing: Figure 1-5 As shown, a rural water supply pipeline antifreeze insulation device includes: a plurality of insulation cottons 100 arranged on the surface of the pipeline and an upper insulation shell 200 and a lower insulation shell 300 installed on the pipeline, and a rotating rod 210 is rotatably connected between the upper insulation shell 200 and the lower insulation shell 300;

[0027] The fixing mechanism 500 includes a plurality of first cylinders 510 fixedly connected to the inner walls of the upper insulation shell 200 and the lower insulation shell 300. A first piston 511 is provided inside the first cylinder 510. One end of the first piston 511 is slidably connected to the inner wall of the first cylinder 510. The other end of the first piston 511 passes through the first cylinder 510 and is fixedly connected to an arc block 513. An adjusting tube 520 is provided inside the upper insulation shell 200 and the lower insulation shell 300. The inner wall of the upper insulation shell 200 is fixedly connected to the second cylinder 530. The top end of the second cylinder 530 is connected to the upper end of the adjusting tube 520.

[0028] like Figure 3 、 Figure 4 and Figure 5 As shown, the inner walls of the upper insulation shell 200 and the lower insulation shell 300 are fixedly connected with multiple limit blocks 521, the adjusting tube 520 is fixedly connected to the inner walls of the multiple limit blocks 521, the multiple first cylinders 510 are connected to the adjusting tube 520, and the top of the second cylinder 530 is connected to the upper end of the adjusting tube 520. A first spring 512 is provided inside the first cylinder 510, one end of the first spring 512 is fixedly connected to the inner wall of the end of the first cylinder 510 away from the arc block 513, and the other end of the first spring 512 is fixedly connected to the first piston 511, the inner bottom wall of the second cylinder 530 is fixedly connected with a second spring 532, the top of the second spring 532 is fixedly connected with the second piston 531, and the second piston 531 is slidably connected to the inner wall of the second cylinder 530, the cross section of the adjusting tube 520 is "C"-shaped, and the bending curvature of the adjusting tube 520 is the same as the curvature of the curved surface of the upper insulation shell 200 and the lower insulation shell 300.

[0029] In this embodiment, the medium communicating among the first cylinder 510, the second cylinder 530 and the regulating tube 520 is gas. The positions of the regulating tube 520 and the first cylinder 510 do not overlap. The first cylinder 510 is connected to the regulating tube 520 through an air pipe. The communication position is located on the surface of the first cylinder 510 near the bottom end. The curvature of the arc block 513 can be set according to the required pipe diameter. Before installation, the amount of gas in the fixing mechanism 500 is equal to the capacity of multiple first cylinders 510. The regulating tube 520 and the air pipe are both made of rubber.

[0030] like Figure 1 、 Figure 3 and Figure 4As shown, the surface of the arc block 513 is fixedly connected to the first Velcro 540, the surface of the insulation cotton 100 is fixedly connected to the second Velcro 541, the surface of the upper insulation shell 200 is fixedly connected to the first fixed block 400, the bottom end of the first fixed block 400 is fixedly connected to the locking rod 420, the inner wall of the locking rod 420 is slidably connected to two locking blocks 421, the two locking blocks 421 are arranged oppositely and the opposite ends are fixedly connected to two third springs 422, and the four third springs 422 are all fixedly connected to the inner wall of the locking rod 420. The surface of the lower insulation shell 300 is fixedly connected to the second fixed block 410, and the surface of the second fixed block 410 is provided with a strip opening with the same shape as the top of the locking rod 420. When the two insulation shells are combined, the two fixed blocks are in a fitted state, the locking blocks 421 are in the shape of a right triangle and are arranged oppositely. The length of the locking rod 420 is equal to the width of the second fixed block 410. When the two locking blocks 421 move relative to each other to the extreme position, the locking rod 420 can be normally withdrawn.

[0031] When the present invention is in use, the heat-insulating cotton 100 is fixed to the arc block 513 through the first Velcro 540 and the second Velcro 541, and then the upper heat-insulating shell 200 is rotated to open, and then the water supply pipe is placed inside the two heat-insulating shells, and then the upper heat-insulating shell 200 is rotated to insert the locking rod 420 into the second fixing block 410. When the two heat-insulating shells are closed, multiple first cylinders 510 are squeezed by the water supply pipe at the same time. Because the pipe is a regular cylindrical shape, the pressure on each first piston 511 is the same, and the gas in the first cylinder 510 is squeezed inward at the same time, and the first cylinder 510 is squeezed out. 0 is squeezed into the regulating tube 520, and then enters the second cylinder body 530 from one end of the regulating tube 520. With the cooperation of the second piston 531 and the second spring 532, the internal pressure of the first cylinder body 510, the second cylinder body 530 and the regulating tube 520 is in a stable state. Under the action of pressure, the arc block 513 applies pressure to the thermal insulation cotton 100, so that the thermal insulation cotton 100 fits the pipeline to complete the insulation of the pipeline. If the thermal insulation cotton 100 needs to be replaced, it is only necessary to squeeze the two locking blocks 421 relative to each other, then open the two insulation shells, and select the thermal insulation cotton 100 that needs to be replaced for replacement.

[0032] It should be noted that the first spring 512 , the second spring 532 and the third spring 422 in the above description are all relatively mature devices in existing technology. The specific models can be selected according to actual needs and will not be described in detail here.

[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
