Description

Technical Field

[0001] The invention belongs to the technical field of pipeline water stopping, and in particular relates to a temporary water stopping peripheral device for a tap water pipe. Background Art

[0002] The tap water pipe is a pipe for water supply. There are three types of water pipes. The first type is metal pipes, such as gray cast iron pipes, ductile iron pipes, steel pipes, copper pipes, stainless steel pipes, etc. The second type is plastic-lined composite metal pipes, such as steel-plastic composite pipes, aluminum-plastic composite pipes, such as plastic-composite steel pipes, aluminum-plastic composite pipes, etc. The third type is PVC pipes. The above three types of water pipes will be damaged after long-term use, that is, cracks will appear, leading to leakage or dripping. For example, cast iron metal pipes will be damaged due to rust, cracks or sand holes after long-term use, and eventually cause leakage or dripping. Before the maintenance personnel arrive, if the dripping and leakage of the tap water pipes are not handled, it is easy to waste water resources.

[0003] In daily life, people usually use pipe clamps to seal and stop leaking pipes. In this water-stopping method, since the pipe clamp is a ring-shaped metal part, it needs to fit perfectly with the surface of the water pipe to seal and stop the water pipe. Therefore, the flatness of the water pipe surface is extremely high. In real life, the surface of the pipe will be reduced due to bumps or manufacturing errors, resulting in reduced fit between the water pipe surface and the pipe clamp. Therefore, after the clamp is installed, it often leaks from the gap between the water pipe surface and the pipe clamp. At the same time, in this water-stopping operation, when the operator uses the pipe clamp to stop water, in order to improve the fit between it and the water pipe to ensure the water-stopping effect, the operator will deform the clamp to the maximum extent. The water pipe, especially the cast iron pipe that has been used for many years, has severe internal corrosion and a thin pipe wall. When the external force is large, it is easy to cause secondary damage to the water pipe, causing the water pipe to burst. Invention content

[0005] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0007] The mounting frame comprises two half rings arranged opposite to each other, the inner ends of the two half rings are hinged, and the outer ends thereof are respectively provided with a connecting ear, and the connecting ears are connected by adjusting bolts, and the inner walls of the two half rings are provided with a through groove along the direction of their respective arcs, and the two through grooves are opposite to each other, and the outer ends of the two half rings are respectively provided with a through hole in the axial direction, and the through hole crosses the two side walls of the through groove;

[0008] Two rotating shafts, each corresponding to a through hole, the inner end of the rotating shaft is movably inserted into the corresponding through hole, and a locking mechanism is provided between the rotating shaft and the half ring;

[0009] The elastic sealing belt is located in the space enclosed by the two semi-rings. The width of the elastic sealing belt is smaller than the width of the through groove. Both ends of the elastic sealing belt are respectively fixed on a rotating shaft.

[0010] Furthermore, the locking mechanism includes a limit block protruding from the outer end of the circumferential surface of the rotating shaft, and a limit groove opened at the outer end of the through hole and corresponding to the limit block, and the limit block is inserted into the limit groove.

[0011] Furthermore, at least two limiting grooves are provided along the circumferential direction of the through hole.

[0012] Furthermore, a magnetic connection structure is provided between the limiting block and the inner wall of the limiting groove.

[0013] Furthermore, the semi-ring is provided with a clamping mechanism corresponding to the elastic sealing belt, the clamping mechanism includes a slide groove respectively opened on the two groove walls of the through groove along the arc direction of the semi-ring, and a slider slidably connected in the two slide grooves, the slider is provided with a threaded hole in the radial direction of the semi-ring, the threaded hole is matched with an extrusion bolt, and an extrusion element is provided after the inner end of the extrusion bolt extends out of the threaded hole, and the extrusion element is arranged opposite to the center of the semi-ring.

[0014] Furthermore, there are two clamping mechanisms, and each of the two clamping mechanisms is arranged on a half ring.

[0015] Furthermore, the extrusion element is an arc-shaped thin-walled part whose curvature is smaller than the curvature of the inner wall of the semi-ring.

[0016] Furthermore, each through groove is provided with a fixing piece at a position adjacent to the outer end of the semi-ring, and the inner surface of the fixing piece is an arc surface structure corresponding to the inner wall of the semi-ring. The fixing piece is provided with a strip hole for the elastic sealing belt to pass through at a position adjacent to the outer end of the semi-ring, and the length of the strip hole is greater than the width of the elastic sealing belt. The two ends of the elastic sealing belt are fixedly connected to the rotating shaft after passing through their respective corresponding strip holes.

[0017] Furthermore, an elastic cushion layer is provided on the inner wall of each half ring, and the elastic cushion layers of the two half rings are provided correspondingly.

[0018] Furthermore, a label slot is provided at the inner end of one of the semi-rings, and a label recording water pipe information is pasted in the label slot.

[0019] Compared with the prior art, the temporary water stopping device for water pipes created by the present invention has the following advantages:

[0020] (1) In this design, the semi-ring, the rotating shaft and the elastic sealing belt work together to tighten the elastic sealing belt on the leaking part of the water pipe to seal the leaking part of the water pipe. At the same time, the rotating shaft rotates to stretch the elastic sealing belt to improve the fit between the elastic sealing belt and the water pipe and improve its sealing effect. This operation method increases the speed of water-stopping operations and facilitates disassembly.

[0021] (2) In this design, an extrusion element for pressing the elastic sealing belt is also provided on the semi-ring. By pressing the elastic sealing belt wrapped on the water pipe with the extrusion element, the fit between the elastic sealing belt and the water pipe is further improved, and the sealing stability of the elastic sealing belt is effectively improved. At the same time, the extrusion element presses the leakage position of the water pipe, which effectively plays a role of secondary reinforcement for the cracks in the water pipe, thereby ensuring the water-stopping effect at the leakage point of the water pipe.

During the water-stopping operation, the two pressing mechanisms are used to respectively press the elastic sealing belt, and the two squeezing points of the elastic sealing belt are located on the left and right sides of the hinge point of the mounting frame, that is, the two squeezing points are located on both sides of the maximum deformation position of the elastic sealing belt. The maximum deformation position of the elastic sealing belt is fixed by this structure to prevent the elastic sealing belt from being suddenly broken due to secondary deformation at the maximum deformation position if it is continuously stretched, thereby ensuring the use function of the elastic sealing belt. At the same time, after the maximum deformation position of the elastic sealing belt is fixed, the elastic sealing belt can be continuously stretched to ensure that the elastic sealing belt can continue to be stretched at positions other than the squeezing points, thereby ensuring that the elastic sealing belt and the pipeline are tightly wrapped, thereby improving its sealing effect.

[0023] (4) In this design, the provision of the elastic gasket increases the friction between the half ring and the water pipe, ensuring a stable connection between the mounting frame and the water pipe, preventing the mounting frame from moving, and thereby improving the feasibility of the water-stopping operation.

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] like Figure 1 As shown, a temporary water-stopping peripheral device for a water pipe includes a mounting frame for fixing to a water pipe 12, and an elastic sealing belt 4 for wrapping and sealing cracks on the water pipe 12. The specific structure is as follows:

[0036] like Figure 2 and3 As shown, the mounting frame includes two half rings 1 arranged opposite to each other, the inner ends of the two half rings 1 are hinged, and the outer ends thereof are respectively provided with a connecting ear 101, and the connecting ear 101 is connected by an adjusting bolt 10. The two half rings 1 are hinged to form a clamp structure, which is a common structure of a clamp and is not described in detail here. In this embodiment, the inner walls of the two half rings 1 are provided with a through groove 102 along the direction of their respective arcs, and the through groove 102 is arranged through the half ring 1. The two through grooves 102 are opposite to each other, and the outer ends of the two half rings 1 are respectively provided with a through hole 103 in the axial direction, and the through hole 103 crosses the two side walls of the through groove 102. A rotating shaft 2 is movably inserted in each of the two through holes 103. For easy operation, a grip is provided at the outer end of the rotating shaft 2. For example, the grip can be a knob structure fixedly provided at the outer end of the rotating shaft 2, which is convenient for manually holding the knob to drive the rotating shaft to rotate; the grip can also be a cylindrical cap body provided at the outer end of the rotating shaft 2, and a hexagonal blind hole structure is provided on the end face of the cap body, through which a hexagonal wrench can be used to drive the rotating shaft to rotate. In this design, a locking mechanism is provided between the rotating shaft 2 and the half ring 1, and the position of the rotating shaft is fixed in time by the locking mechanism. The elastic sealing band 4 is preferably a rubber band with a thickness of 1-3 mm, which is located in the space enclosed by the two semi-rings 1. The width of the elastic sealing band 4 is smaller than the width of the through groove 102, so as to ensure that after the elastic sealing band 4 moves outward for a certain distance along the axis of the semi-rings with the rotating shaft 2, the elastic sealing band 4 will not wrinkle and can remain flat. The two ends of the elastic sealing band 4 are respectively fixed on a rotating shaft 2. For example, the elastic sealing band 4 can be fixed to the rotating shaft 2 by screws, or the end of the elastic sealing band 4 can be bonded and fixed to the rotating shaft 2 by an adhesive. When the bonding fixing method is adopted, in order to improve the bonding firmness, it is necessary to ensure that the corresponding circumferential length of the rotating shaft bonding area is not less than 1 / 2 of the circumferential length of the rotating shaft, that is, the corresponding central angle of the rotating shaft bonding area is not less than 180°. In this design, the elastic sealing belt 4 is stretched by rotating the rotating shaft 2 on the semi-ring so that it can wrap tightly around the leaking point of the pipe 12, thereby sealing and stopping the leaking point of the pipe. After the sealing effect is achieved, the locking mechanism fixes the position of the rotating shaft 2. At this time, the elastic sealing belt 4 stably seals the water pipe, achieving the temporary water-stopping effect of this design. Compared with the water pipe clamp water-stopping, in this design, the water pipe is sealed and stopped by the elastic sealing belt 4. The elastic sealing belt 4 itself has the function of elastic deformation, so it has a very high degree of fit with the surface of the water pipe and can seal the water pipe perfectly. At the same time, the force between the elastic sealing belt 4 and the water pipe has a certain flexibility, which to a certain extent prevents the occurrence of artificial damage to the water pipe during the water-stopping operation.

[0037] In this embodiment, the locking mechanism includes a stopper 3 protruding from the outer end of the circumferential surface of the rotating shaft 2, and a stopper groove 14 formed at the outer end of the through hole 103 and corresponding to the stopper 3. Figure 4As shown. The limiting grooves 14 are provided with at least two along the circumferential direction of the through hole 103. In order to facilitate manual and quick insertion of the limiting block into the limiting groove 14, in this embodiment, a boss is protruded from the outer end side of the semi-ring 1, the through hole is opened through the boss, the limiting groove 14 is opened on the boss, and the limiting groove 14 passes through the boss entity. This structure is convenient for operators to quickly correspond the position of the limiting block and the limiting groove to increase the speed of inserting the limiting block 3 into the limiting groove 14. The number of limiting blocks 3 can be one, or it can be equal to the number of limiting grooves 14 and set one-to-one with the limiting grooves 14. When there is one limiting block 3, the limiting block 3 is inserted into one of the limiting grooves 14. When the number of limiting blocks 3 is equal to the number of limiting grooves 14, the limiting blocks 3 are each inserted into a limiting groove 14, and the rotating shaft is locked and fixed in the circumferential direction by the locking mechanism to prevent it from rotating. When operating to stop water from flowing into the water pipe, first fix the mounting bracket on the water pipe 12. The mounting position of the mounting bracket ensures that the water leakage point on the water pipe 12 is close to the inner end of the semi-ring 1. Then pull the two rotating shafts 2 outwards respectively until the limit block 3 is moved out of the limit groove 14. At this time, the rotating shaft 2 can rotate freely in the through hole 103. Rotate the rotating shaft 2, and the rotating shaft 2 begins to wrap around the elastic sealing belt 4. The elastic sealing belt 4 is stretched until it tightly wraps the water pipe 12. At this time, the elastic sealing belt 4 and the water pipe 12 fit tightly to seal and stop the water outlet of the water pipe 12. Then reinsert the rotating shaft 2 into the through hole 103, and ensure that the limit block 3 is inserted into the limit groove 14. The rotating shaft 2 returns to its initial position. The limit groove-limit block matching structure realizes the limitation of the rotational freedom of the rotating shaft in the circumferential direction, ensuring that the elastic bandage stably seals the water pipe. In this embodiment, after the elastic sealing belt 4 tightly wraps and seals the water pipe 12, in order to ensure its tight state, the shaft 2 needs to be moved back into the through hole and locked by the locking mechanism. During this operation, since the elastic sealing belt itself has a deformation function, the flatness of the part wrapped around the water pipe can still be ensured. In this design, the corresponding insertion length of the limit groove 14 and the limit block 3 is set to 3-5mm. At this time, the axial movement distance of the shaft 2 is small. It is sufficient to ensure that the limit block 3 is moved out of the limit groove 14. This distance allows the elastic sealing belt 4 to rely on its own deformation to compensate for the impact of the position change, prevent the outer end of the elastic sealing belt 4 from wrinkling, and basically ensure the flatness of the elastic sealing belt 4.

[0038] In this embodiment, in order to prevent the axial movement of the rotating shaft, a magnetic connection structure is provided between the limit block 3 and the inner wall of the limit groove 14. Specifically, a magnet 15 is provided on the limit block 3, and the magnet 15 is inserted into the limit groove 14 and adsorbed and connected to the inner wall of the limit groove. In this design, when the mounting frame is a cast iron part, after the limit block 3 is inserted into the limit groove 14, the magnet 15 and the groove wall of the limit groove 14 are directly adsorbed and fixed. If the mounting frame is made of non-magnetic conductive material, an iron sheet can be installed in the limit groove 14 and at the position corresponding to the magnet. When the limit block 3 is inserted into the limit groove, the magnet 15 and the iron sheet are adsorbed to fix the axial position of the rotating shaft 2, that is, the axial freedom of the rotating shaft is limited, the axial movement of the rotating shaft is prevented, and the sealing stability of the elastic sealing belt is ensured. During the water-stopping operation, there is no operating force in the axial direction of the rotating shaft 2, so the adsorption force does not need to be very large to achieve the axial limitation of the rotating shaft.

[0039] In this embodiment, the semi-ring 1 is provided with a pressing mechanism corresponding to the elastic sealing band 4, the pressing mechanism includes a slider 6, a slide groove 7 respectively provided on the two groove walls of the through groove 102 along the arc direction of the semi-ring 1, the slider 6 is slidably installed in the two slide grooves 7, the slider 6 is provided with a threaded hole in the radial direction of the semi-ring 1, and the threaded hole is matched with an extrusion bolt 8, and an extrusion element 9 is provided after the inner end of the extrusion bolt 8 extends out of the threaded hole, and the extrusion element 9 is arranged opposite to the center of the semi-ring 1, and the extrusion element 9 is located in the through groove 102, that is, the extrusion element 9 is located outside the inner wall of the semi-ring 1. After the elastic sealing band 4 presses and seals the water pipe 12, adjust the position of one of the sliders 6 so that the extrusion element 9 faces the leakage point of the water pipe 12, and then screw in the extrusion bolt 8 until the extrusion element 9 presses the elastic sealing band 4, and the extrusion element 9 further fixes the position of the elastic sealing band 4, and further ensures the fit between the elastic sealing band and the water pipe, and ensures its water-stopping effect. In this embodiment, a pressing mechanism is provided on each half ring 1. After the elastic sealing belt 4 wraps and seals the water pipe 12, the elastic sealing belt 4 is pressed by the extrusion element 9 at the left and right positions of the leakage point of the water pipe 12. At this time, the maximum deformation position of the elastic sealing belt is fixed. According to actual needs, the rotating shaft can continue to rotate, and the elastic sealing belt 4 is continuously stretched, which can further improve the tightening effect of the elastic sealing belt 4. At this time, the elastic sealing belt 4 is stretched outside the extrusion element 9, that is, the elastic sealing belt 4 is stretched and deformed at the position outside the extrusion element 9. The elastic sealing belt 4 will not be stretched and deformed at the part between the two extrusion elements. It is prevented that the elastic sealing belt 4 is torn due to continuous stretching, and the elastic sealing belt 4 is ensured to be used normally.

[0040] In this embodiment, the extrusion element 9 is an arc-shaped thin-walled part with an arc smaller than the inner wall of the semi-ring 1. During the extrusion process, the extrusion element 9 itself can be deformed, and after the extrusion element 9 is deformed, it can fit completely with the elastic sealing belt 4, and can press and seal the deformed elastic sealing belt, thereby improving the sealing effect of the elastic sealing belt.

[0041] In this embodiment, each through groove 102 is provided with a fixing member 5 at a position adjacent to the outer end of the semi-ring 1, and the inner surface of the fixing member 5 is a curved surface structure corresponding to the inner wall of the semi-ring 1. The fixing member 5 is provided with a strip hole 51 for the elastic sealing belt 4 to pass through at a position adjacent to the outer end of the semi-ring 1, and the openings of the strip hole at both ends are rounded. The two ends of the elastic sealing belt 4 pass through the corresponding strip holes 51 and are fixedly connected to the rotating shaft 2. In this design, the length of the strip hole 51 is greater than the width of the elastic sealing belt 4, so as to ensure that the elastic sealing belt 4 will not wrinkle when moving axially with the rotating shaft, and can maintain flatness.

[0042] In this embodiment, an elastic cushion layer 13 is provided on the inner wall of each half ring 1, and the elastic cushion layers 13 of the two half rings 1 are provided correspondingly. During installation, the half ring is provided with an elastic cushion layer 13, and the provision of the elastic cushion layer 13 improves the connection stability between the half ring and the water pipe.

[0043] In order to record the maintenance information of the water pipe 12 , in this embodiment, a label slot 11 is provided at the inner end of one of the half rings, and a label recording the water pipe information is pasted in the label slot 11 .

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
