Description

Technical Field

[0001] The invention relates to the technical field of drainage equipment, and in particular to a rubber sleeve with a mounting structure and a pipeline for mounting the sleeve. Background Art

[0002] The flexible intercepting device is an intercepting facility used at the outlet or discharge port of a diversion well. Its structure generally includes an outer shell and a rubber sleeve. A pressurized cavity is formed between the outer shell and the rubber sleeve. The end of the rubber sleeve is sealed and connected to the end of the outer shell through a flange. When pressurized gas is filled into the pressurized cavity, the rubber sleeve is relatively deformed inward, the inner wall of the rubber sleeve is fitted, and the flow channel is cut off. However, when the diameter of the drainage pipe or discharge port connected to the diversion well is large (such as a diameter of DN400 or more), the diameter of the rubber sleeve cannot be large and the deformation is large. At this time, the end of the rubber sleeve and the end of the outer shell are greatly deformed, and the end of the rubber sleeve slides out between the flange and the end of the outer shell, and the pressurized cavity is not well sealed. Moreover, the structure of the outer shell generally adopts a rigid structure, but the pipeline for installing the flexible intercepting device is also immutable. The outer shell of the flexible intercepting device is not well matched with the pipeline, and the end of the outer shell is often connected to the end of the pipeline. The flexible intercepting device cannot be installed in the pipeline, and it is necessary to occupy the end of the pipeline to set up an installation well. When the specification of the flexible intercepting device is larger, the required installation well is also larger, the infrastructure construction project is large, the construction efficiency is low and the cost is high, and the later maintenance is inconvenient. Therefore, a flexible intercepting device that can solve the sealing problem and is easy to install is urgently needed. Summary of the invention

[0028] Compared with the prior art, the advantages of the present invention are as follows:

[0029] (1) The rubber sleeve with an installation structure of the present invention can only adopt a rubber sleeve structure, and a pressure chamber is set in the rubber sleeve. The entire rubber sleeve is an integrated structure. Compared with the prior art, there is no problem of sealing the pressure chamber, the structure is simpler, and it is easy to install and use; the rubber sleeve is clamped and fixed by the limiting parts set at both ends of the rubber sleeve. When installing and maintaining the rubber sleeve in the later stage, it only needs to be removed from the limiting parts at both ends, which is convenient for installation and maintenance.

[0030] (2) The rubber sleeve with a mounting structure of the present invention is provided with an independent pressure-charging chamber or two independent pressure-charging chambers. In addition to the traditional function of closing the flow channel, the rubber sleeve also has a flow-blocking function. Only the lower pressure-charging chamber can be pressurized. The inner rubber layer of the lower pressure-charging chamber bulges upward. The lower half of the rubber sleeve after inflation and deformation is equivalent to an adjustable weir with an adjustable height. When the water level rises above the flow-blocking height, water can overflow from above. In this way, the accumulated mud at the bottom of the pipeline or the accumulated mud in the diversion well can be intercepted to prevent the accumulated mud at the bottom from entering the natural water body with rainwater and polluting the natural water body. In addition, when used at the drain outlet, the flow-blocking height of the lower half of the rubber sleeve can be adjusted according to the natural water level to prevent the backflow of natural water bodies. While preventing backflow, the overflow from the top of the lower half of the rubber sleeve does not affect the flow of flood water.

[0031] (3) The rubber sleeve with a mounting structure of the present invention is designed to be deformed in three directions or four directions to close the intercepting channel. The sealing member is filled in the gap at the closed position of the rubber sleeve, and the air pressure used to close the rubber sleeve is relatively small, so zero leakage can be achieved at a relatively low pressure (less than 2 bar). The sealing effect is good, the air pressure is low, the sealing structure is simple, and the flow capacity of the flow channel is not affected. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] Example 1

[0052] See also Figures 1 to 13As shown, the present invention provides a rubber sleeve with a mounting structure, including a rubber sleeve 1 and a mounting structure, wherein the rubber sleeve 1 is provided with a through-flow channel 10, the rubber sleeve 1 is an integral structure, and at least one independent pressurized chamber 11 is provided inside the rubber sleeve 1, the rubber sleeve 1 is an integrated structure, and at least one independent pressurized chamber 11 is provided inside the rubber sleeve 1, and the rubber sleeve 1 at the location of each pressurized chamber 11 has an outer rubber layer 12 and an inner rubber layer 13; an inlet and outlet hole is provided on the outer rubber layer 12 of each pressurized chamber 11, and the inlet and outlet hole is connected to the pressurized chamber 11; the mounting structure includes two limiting parts 2, and the two limiting parts 2 are fixed at both ends of the rubber sleeve 1 to clamp the rubber sleeve 1. In this embodiment, the rubber structure forming the pressurized chamber 11 is an integral structure with the rubber structure at other positions. Since the rubber sleeve 1 does not form the pressurized chamber 11 together with other components, there is no need to provide a sealing structure for sealing the pressurized chamber 11 to prevent leakage of the pressurized chamber 11, and the structure is simple, easy to install, and has a wide range of applications. The rubber sleeve 1 is only fixed at two ends, and no mounting structure is provided on the tube body of the rubber sleeve 1, so that the disassembly is convenient, and the installation and maintenance are easy to operate.

[0053] Preferably, as a specific implementation, the structure of the rubber sleeve 1 has the following forms:

[0054] The structural form of the rubber sleeve 1 is shown in FIG. Figure 2 As shown, in this embodiment, the rubber sleeve 1 is cylindrical, and the pressure chamber 11 in the rubber sleeve 1 is also cylindrical. The rubber sleeve 1 is provided with an inlet and outlet hole. The pressure chamber 11 is pressurized through the inlet and outlet hole, the rubber sleeve 1 is deformed, and the flow channel 19 is cut off. The pressure chamber 11 is pressurized through the inlet and outlet hole, the rubber sleeve 1 recovers its deformation, and the flow channel 19 is connected.

[0055] The second structural form of the rubber sleeve 1 is shown in FIG. Figure 4 and Figure 5As shown, the cross-sectional shape of the rubber sleeve 1 is circular. When a pressure chamber 11 is provided, the pressure chamber 11 is a lower pressure chamber 111. The cross-sectional shape of the lower pressure chamber 111 is arc-shaped. The arc length of the cross-sectional shape of the lower pressure chamber 111 is smaller than the circumference of the rubber sleeve 1 at the cross-sectional shape. The rubber sleeve 1 at the position of the lower pressure chamber 111 has an outer rubber layer 12 and an inner rubber layer 13, and the outer rubber layer 12 and the inner rubber layer 13 and the rubber sleeve 1 outside the pressure chamber 11 are an integral structure. The arc length of the lower pressure chamber 111 can account for one-half or two-thirds of the circumference of the entire rubber sleeve 1. Different specifications can be designed according to different interception heights. The higher the interception height, the more the arc length of the lower pressure chamber 11 approaches the circumference of the rubber sleeve. The outer rubber layer 12 of the lower pressure chamber 111 is provided with an inlet and outlet hole, which is connected to the pressure chamber 11. When pressure is charged through the inlet and outlet holes, the inner rubber layer 13 on the side where the lower pressure chamber 111 is located rises to a certain height, which is equivalent to a weir with adjustable height. When the inner rubber layer 13 fits the inner wall of the rubber sleeve 1 in the upper part, the flow channel 19 is cut off. When the inner rubber layer 13 of the lower pressure chamber 111 in the lower part of the structure rises to a certain height, the top space can overflow, which can block part of the mud and sand garbage from entering the downstream, and can also prevent backflow when the water level in the downstream is too high.

[0056] The third structural form of the rubber sleeve 1 is shown in FIG. Figure 6 and Figure 7 As shown, two independent pressure chambers 11 are provided, namely an upper pressure chamber 110 and a lower pressure chamber 111. The upper pressure chamber 110 and the lower pressure chamber 111 are respectively provided on the upper and lower sides of the rubber sleeve 1. The outer rubber layer 12 on the side where the upper pressure chamber 110 is located is provided with an upper inlet and outlet hole connected to the upper pressure chamber 110, and the outer rubber layer 12 on the side where the lower pressure chamber 111 is located is provided with a lower inlet and outlet hole connected to the lower pressure chamber 111.

[0057] The fourth structural form of the rubber sleeve 1 is shown in FIG. Figure 8 As shown, three independent pressure chambers 11 are provided, which are divided into three parts along the circumference of the rubber sleeve 1, and each rubber sleeve 1 is provided with a pressure chamber 11; or, see Fig. 9As shown, four independent pressure chambers 11 are provided, which are divided into four parts along the circumference of the rubber sleeve 1. Each rubber sleeve 1 is provided with a pressure chamber 11, and each pressure chamber 11 is provided with an inlet and outlet hole. As a preferred embodiment, the rubber sleeve 1 should be divided into three or four equal parts to ensure that the inner rubber layer of each rubber sleeve 1 has the same deformation and the same pressure, which is convenient for control. For a relatively large rubber sleeve 1, if one or two half structures are relatively deformed to cut off the flow channel 10, if the diameter of the flow channel 10 is large, the deformation of the rubber sleeve 1 on the upper and lower sides is large, and the required pressure is large, which not only has a poor sealing effect, the flow channel 10 cannot achieve zero leakage, but also has a safety hazard of explosion. By using the three-way or four-way deformation to close the flow channel of this embodiment, the inner rubber layer of each independent pressure chamber has a small deformation, and the required pressure is small, which is safe and reliable, has a good sealing effect, and has a wide range of uses.

[0058] Further preferably, the inlet and outlet holes in this embodiment can be two holes arranged on the outer rubber layer 12, or can be one hole arranged on the outer rubber layer 12, and an inlet pipeline and an outlet pipeline are arranged on the delivery pipeline connected to the hole.

[0059] Further preferably, the specific structure of the limiting portion 2 in this embodiment has the following forms:

[0060] The structure of the limiting part 2 is shown in FIG. Figure 3 As shown, the limiting part 2 includes a bending part and an expansion bolt, the bending part has a horizontal part 20 and a vertical part 21 connected in one body, the horizontal part 20 is provided with a mounting hole, the horizontal part 20 is fixed in the pipeline by the expansion bolt, the outer side of the vertical part 21 is abutted against the end of the rubber sleeve 1, and the vertical parts 21 of the limiting parts 2 at both ends work together to clamp the rubber sleeve 1, wherein there are multiple bending parts, which are arranged at intervals at the ends of the rubber sleeve 1 for easy disassembly, or the bending parts are arranged as an integrated structure, the shape of the vertical part 21 of the bending part is adapted to the shape of the end of the rubber sleeve 1, and the shape of the horizontal part 20 of the bending part is adapted to the shape of the port of the pipeline under the installation environment;

[0061] The structure of the limiting part 2 is shown in FIG. Fig.13As shown, the limiting part 2 includes a bending part, and the bending part has a horizontal part 20 and a vertical part 21 which are connected as one body. The horizontal part 20 and the vertical part 21 are both provided with mounting holes. The horizontal part 20 is provided with a mounting hole, and the horizontal part 20 is fixed in the pipeline by expansion bolts. A connecting plate 22 is provided at the end of the rubber sleeve 1, and the vertical part 21 is connected to the connecting plate 22, wherein a circumferential mounting groove for mounting the connecting plate 22 is provided at the end of the rubber sleeve 1, and the cross-sectional width of the mounting groove on one side close to the vertical part 21 is smaller than the cross-sectional width on the other side, presenting a horizontal "T"-shaped structure, and the shape of the vertical part 21 of the bending part is adapted to the shape of the connecting plate 22, and the shape of the horizontal part 20 of the bending part is adapted to the shape of the port of the pipeline under the installation environment;

[0062] The structure of the limiting part 2 is shown in FIG. Fig.14 As shown, the limiting portion 2 includes a connected fixed end 23 and a hook 24, and an ear plate 25 is provided at the end of the rubber sleeve 1, and the ear plate 25 is detachably connected to the hook 24, wherein the fixed end 23 is an expansion bolt. In the installed state, one end of the expansion bolt is fixed in the port of the pipe or the offset port, and the hook 24 is connected to the other end of the expansion bolt, and the ear plate 25 is connected to the hook 24. When it needs to be removed, the ear plate 25 and the hook 24 are removed, and the hook is removed from the end of the expansion bolt. The installation and maintenance are simple and easy to operate.

[0063] The structure of the limiting part 2 is shown in FIG. Figure 15-17 As shown, it can be understood that among the two limiting parts 2, one of the limiting parts 2 includes a pressure plate 41 and a first fixing ring 421. The first fixing ring 421 is a metal ring with an annular structure, which is embedded in one end of the rubber sleeve 1. A mounting hole is provided on the pressure plate 41. During installation, one end of the expansion bolt can be passed through the mounting hole to fix it at the end of the pipe. At the same time, the pressure plate 41 is pressed against one end of the rubber sleeve to fix one end of the rubber sleeve 1 at the end of the pipe. The other limiting part 2 includes a second fixing ring 422. The second fixing ring 422 is a metal ring with an annular structure, which is embedded in the other end of the rubber sleeve 1. Combined with the attached Figure 15-17Those skilled in the art can understand that in the structural mode of the limiting portion 2, the rubber sleeve 1 can be directly inserted into the existing pipeline for direct installation, with a simple structure and a small installation space. In order to make the outer wall of the rubber sleeve 1 and the inner wall of the pipeline contact more closely, an outer cover body 44 is further provided in the present embodiment. The outer cover body 44 is sleeved on the outer portion of the rubber sleeve 1 and is located between the outer wall of the rubber sleeve 1 and the inside of the pipeline, so that the installation of the rubber sleeve 1 in the pipeline is more stable. At the same time, the first fixing ring 421 and the second fixing ring 422 can respectively support the two ends of the rubber sleeve 1, and the first fixing ring 421 and the second fixing ring 422 can be integrated and embedded in the flexible sleeve, or can be made detachable and installed separately, so as to achieve the technical effect of simple installation and maintenance and easy operation.

[0064] Furthermore, in this embodiment, a dirt blocking portion 43 with a raised structure may be provided on one end and / or the other end of the rubber sleeve 1 to prevent pollutants such as sludge and residues in the pipeline from flowing into the gap between the rubber sleeve 1 and the outer cover body 44 and causing additional cleaning and maintenance costs.

[0065] Of course, the four structural modes of the above-mentioned limiting portion 2 are only four implementation modes of the mounting structure in the rubber sleeve with the mounting structure. Similarly, the structural forms one, two, and three of the rubber sleeve 1 are also only multiple implementation modes of the rubber sleeve. Those skilled in the art can understand that the multiple implementation modes of the limiting portion 2 and any combination of the multiple implementation modes of the rubber sleeve 1, resulting in several types of rubber sleeves with mounting structures, are all suitable for the present invention and are within the protection scope of the present invention. Other combinations not included in the embodiments of the present invention cannot be excluded on the grounds that the embodiments of the present invention do not exhaust all the combinations.

[0066] Example 2

[0067] Based on Example 1, see Figure 1 and Fig.12 As shown, a pipe, a rubber sleeve with a mounting structure of embodiment 1 is installed in a port 3 of the pipe;

[0068] The outer wall of the rubber sleeve 1 fits with the inner wall of the port 3 of the pipe, the limiting parts 2 of the mounting structure 2 are fixed on the inner walls of the port 3 of the pipe at both ends of the rubber sleeve 1, and the rubber sleeve 1 is clamped between the limiting parts 2.

[0069] Or see Figure 15-17Another pipe shown in the figure has a rubber sleeve with a mounting structure of Example 1 installed in the port 3 of the pipe; the outer wall of the rubber sleeve 1 is fitted with the inner wall of the port 3 of the pipe through the outer cover body 44, the limiting portion 2 of the mounting structure 2 is fixed to the port of the pipe, and is pressed against one end of the rubber sleeve 1 through a pressure plate, and one end of the rubber sleeve 1 is supported by an embedded first fixing ring, and a second fixing ring is also embedded in the other end of the rubber sleeve 1, and the other end of the rubber sleeve 1 is supported by the second fixing ring.

[0070] The structure of the rubber sleeve in this embodiment selects the interception height according to the use. The lower pressure chamber 111 is pressurized to a certain height. At this time, the height of the inner rubber layer of the lower pressure chamber 111 is equivalent to a weir with adjustable height. When the pressure is large, the bulge height is high and the interception height is also high. When the pressure is small or after the pressure is released, the bulge height is low and the interception height is also low. The pressure can be controlled according to the actual use. When the water level rises above the interception height, water can overflow from above. In this way, the mud at the bottom of the pipeline or the mud in the diversion well can be intercepted to prevent the mud at the bottom from entering the natural water body with rainwater and polluting the natural water body. In addition, when used at the drain outlet, the interception height of the lower half of the rubber sleeve can be adjusted according to the natural water level to prevent the backflow of natural water bodies. While preventing backflow, the overflow from the top of the lower half of the rubber sleeve does not affect the flood discharge.

[0071] Those skilled in the art may make various modifications and variations to the embodiments of the present invention. If these modifications and variations are within the scope of the claims of the present invention and their equivalents, these modifications and variations are also within the protection scope of the present invention.

[0072] The contents not described in detail in the specification are prior art known to those skilled in the art.
