Description

Technical Field

[0001] The utility model relates to the field of slotted pipes, in particular to a sealing structure for a slotted pipe connection. Background Art

[0002] As a vital component of water conservancy projects, dams undertake multiple functions, including flood control, irrigation, and power generation. During dam construction and operation, the design and implementation of fluid transport systems is a key step in ensuring the proper functioning of the dam. Slotted pipes, as an effective means of fluid transport, are widely used in dam projects.

[0003] According to the disclosed patent 202322998067.6, a pipeline connection structure is known, including a first pipeline, a first convex ring is fixedly connected to the outer side of the right end of the first pipeline, and a first annular groove is opened at the right end of the first pipeline, a second pipeline is provided on the right side of the first pipeline, and the second pipeline is fixedly connected to the second convex ring in the opposite direction of the first pipeline, and a second annular groove is opened at the left end of the second pipeline. The structures of the first pipeline and the second pipeline are opposite, and a sealing ring is provided inside when the first annular groove and the second annular groove are connected, and the outer side of the sealing ring generally fits in the first annular groove, and the other half of the sealing ring fits in the second annular groove. At the same time, a connecting sealing structure is provided at the connection between the first pipeline and the second pipeline. By setting the connecting sealing structure and the sealing ring, the sealing performance of the pipeline connection is improved, and then by setting the fixing component, pipelines of different calibers can be clamped and fixed, thereby improving the versatility of the fixing component.

[0004] However, the sealing mechanisms at the joints of traditional slotted pipes are typically passive, relying on pre-set sealing elements to ensure the tightness of the pipe joints. This sealing mechanism often only allows for manual detection and repair after a leak occurs, preventing immediate response and rapid resolution. Furthermore, after the pipeline is laid and commissioned, especially when it is deeply buried, the overlying soil may collapse or sink due to natural factors (such as rain erosion and soil loosening) or human activities (such as heavy vehicle traffic and construction vibration). In this case, the soil directly impacts the pipe joints, potentially causing ruptures due to increased local pressure and displacement of the joints, which could compromise the original sealing structure and lead to leaks. Therefore, new technical solutions are needed to address this issue. Utility Model Content

[0005] The present utility model aims to overcome the shortcomings of the prior art and meet current needs by providing a sealing structure for slotted pipe joints. This solution addresses the current problem of traditional slotted pipe joints, where the sealing mechanism typically relies on a passive mechanism, relying on pre-set sealing elements to ensure the tightness of the pipe joints. This sealing mechanism often requires manual inspection to detect anomalies after a leak occurs, and then intervention and repair are required, failing to provide an immediate response and rapid resolution to the leak. Furthermore, after the pipeline is laid and put into operation, especially when the pipeline is deeply buried, the overlying soil may collapse or sink due to natural factors (such as rain erosion and soil loosening) or human activities (such as heavy vehicle traffic and construction vibration). In such cases, the soil directly impacts the pipe joint, potentially causing not only rupture of the joint due to increased local pressure but also displacement of the pipe joint, thereby damaging the original sealing structure and causing leakage.

[0006] In order to achieve the purpose of the present invention, the technical solution adopted by the present invention is: to design a sealing structure at the slotted pipe connection, including a connecting sleeve, limiting rings are installed on both sides of the connecting sleeve, a pipe base is installed at the bottom of the connecting sleeve, a leaking power generation component is provided on the surface of the pipe base, circular grooves are provided at the front and rear ends of the pipe base, and a sealing component is installed inside the circular groove.

[0007] Preferably, the water leakage power generation component includes a first groove, a second groove, and a water battery. The first groove is opened at the bottom of both sides of the pipe base, and the second groove is opened at the top of both sides of the pipe base.

[0008] Preferably, the first groove is communicated with the second groove, a water battery is installed inside the first groove, and a partition net is installed on the top of the second groove.

[0009] Preferably, the sealing assembly includes an air storage tank, a solenoid valve, a hose, an annular groove, an annular sealing airbag, a connecting pipe, a pipe connector, and a pipe connection housing.

[0010] Preferably, the gas storage tank is installed in a circular groove, one end of the gas storage tank is connected to a solenoid valve, and the end of the solenoid valve away from the gas storage tank is connected to a hose.

[0011] Preferably, both sides of the pipeline connection shell are connected with pipeline connectors, the pipeline connector and the inner wall of the limiting ring are provided with annular grooves, annular sealing airbags are installed inside the annular grooves, and a connecting pipe is connected between the two annular sealing airbags.

[0012] Preferably, one end of the hose away from the battery valve passes through a limiting ring and is communicated with the annular sealing airbag in the limiting ring.

[0013] Preferably, arc-shaped support plates are installed on the tops of both the front and rear ends of the connecting sleeve.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model combines a limiting ring, an air storage tank and a leaking power generation component. After a leak occurs at the connection of the pipeline, the leaking power generation component will directly generate electricity when it comes into contact with water, thereby starting the solenoid valve and inflating the annular sealing airbag in the limiting ring, causing the annular sealing airbag to expand rapidly. The annular sealing airbag is used to clamp and seal the pipeline and the limiting ring, thereby preventing water from flowing out, achieving active sealing of the leaking water, and improving the sealing effect. It solves the current problem that the sealing mechanism at the connection part of the traditional slotted pipeline usually adopts a passive method, that is, it relies on a preset sealing element to ensure the airtightness of the joint of the pipe section. This sealing mechanism can often only be discovered through manual detection after the leak occurs, and then intervention and repair are performed, and it is impossible to achieve an immediate response to the leakage problem and a rapid solution.

[0016] 2. The utility model sets the position of the pipe connection inside the connecting sleeve through the combination of the connecting pipe, the pipe connector and the pipe connection shell. After the pipe connection leaks, the connecting sleeve can be used to collect water. At the same time, when the connecting sleeve is filled with leaked water, the water battery generates electricity, and the annular sealing airbag in the limit ring is filled with air, which will input the gas into the annular sealing airbag in the pipe connector. The annular sealing airbag in the pipe connector is used to seal the position of the pipe connection, thereby achieving a double sealing effect, solving the current problem that the sealing mechanism at the connection part of the traditional slotted pipe usually adopts a passive method, that is, it relies on a preset sealing element to ensure the airtightness of the joint of the pipe section. This sealing mechanism can often only be discovered through manual detection after the leakage occurs, and then intervention and repair are performed, and it is impossible to achieve an immediate response to the leakage problem and a quick solution.

[0017] 3. The present invention combines a connecting sleeve with an arc-shaped support plate, allowing the arc-shaped support plates to be positioned on either side of the connecting sleeve to protect the top of the pipes on both sides. Even if the soil above collapses, the arc-shaped support plates can provide support, preventing the pipes from being directly subjected to pressure. This solves the problem that after the pipeline is laid and put into operation, especially when the pipeline is deeply buried, the overlying soil may collapse or sink due to natural factors (such as rain erosion, soil loosening) or human activities (such as the passage of heavy vehicles, construction vibrations). In this case, the soil directly acts on the pipe connection, which may not only cause the connection to rupture due to increased local pressure, but also cause displacement of the pipe joint, thereby destroying the original sealing structure and causing water leakage.

[0023] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0024] Example 1: Sealing structure of slotted pipe joint, see Figures 1 to 4, including a connecting sleeve 1, with limit rings 207 installed on both sides of the connecting sleeve 1, a pipe base 101 installed at the bottom of the connecting sleeve 1, a water leakage power generation component set on the surface of the pipe base 101, circular grooves 203 are opened at the front and rear ends of the pipe base 101, and a sealing component is installed inside the circular groove 203. When water leaks at the pipe connector 211 on both sides of the pipe connection shell 212, the connecting sleeve 1 will collect the leaked water. After the connecting sleeve 1 is full of water, the water will leak downward from the position of the limit ring 207, and the leaked water will enter the second groove 202 and flow into the first groove 2. Since a water battery 201 is provided in the first groove 2, the water battery 201 will generate electricity after contacting water, thereby starting the solenoid valve 205. After the solenoid valve 205 is opened, the gas in the gas tank 204 will directly pass through the hose 206. , enters the annular sealing airbag 210 in the limiting ring 207, causing the annular sealing airbag 210 to expand rapidly, clamping and sealing the pipe and the limiting ring 207, thereby preventing water from flowing out. After the annular sealing airbag 210 in the limiting ring 207 is filled with air, the gas will be input into the annular sealing airbag 210 in the pipe connector 211, and the annular sealing airbag 210 in the pipe connector 211 is used to seal the position of the pipe connection, thereby achieving a double sealing effect, solving the current problem that the sealing mechanism at the connection part of the traditional slotted pipe usually adopts a passive method, that is, relying on a preset sealing element to ensure the airtightness of the pipe section joint. This sealing mechanism can often only be discovered through manual detection after the leakage occurs, and then intervention and repair are carried out, and it is impossible to achieve an immediate response to the leakage problem and a quick solution to the technical problem.

[0025] For details, see Figure 1 and Figure 2 The leaking power generation component includes a first groove 2, a second groove 202, and a water battery 201. The first groove 2 is opened at the bottom of both sides of the pipe base 101, and the second groove 202 is opened at the top of both sides of the pipe base 101.

[0026] For more details, see Figure 1 The first groove 2 is connected to the second groove 202 , a water battery 201 is installed inside the first groove 2 , and a partition net 208 is installed on the top of the second groove 202 .

[0027] For further information, see Figure 1 、 Figure 3 and Figure 4 The sealing assembly includes an air storage tank 204, a solenoid valve 205, a hose 206, an annular groove 209, an annular sealing airbag 210, a connecting pipe 213, a pipe connector 211, and a pipe connecting shell 212.

[0028] Further, see Figure 1The gas tank 204 is installed in the circular groove 203 , one end of the gas tank 204 is connected to the solenoid valve 205 , and the end of the solenoid valve 205 away from the gas tank 204 is connected to the hose 206 .

[0029] It is worth noting that, see Figure 3 Both sides of the pipe connection shell 212 are connected with pipe connectors 211, and the inner walls of the pipe connector 211 and the limiting ring 207 are provided with annular grooves 209. An annular sealing airbag 210 is installed inside the annular groove 209, and a connecting pipe 213 is connected between the two annular sealing airbags 210.

[0030] It is worth noting that see Figure 4 The end of the hose 206 away from the battery valve passes through the limiting ring 207 and is connected to the annular sealing airbag 210 in the limiting ring 207.

[0031] It is worth mentioning that see Figure 1 Arc-shaped support plates 3 are installed at the tops of both ends of the connecting sleeve 1. These plates 3 are positioned on either side of the connecting sleeve 1 to protect the tops of the pipes on both sides. If the soil above collapses, the plates 3 can be used to support the pipes, preventing them from being directly subjected to pressure. This addresses the issue of overlying soil collapsing or sinking due to natural factors (such as rain erosion and soil loosening) or human activities (such as heavy vehicle traffic and construction vibrations) after the pipes are laid and put into operation, especially when the pipes are deeply buried. In this case, soil directly impacts the pipe connection, potentially causing rupture due to increased local pressure and displacement of the pipe joints, which can damage the original sealing structure and lead to water leakage.

[0032] When the slotted pipe connection sealing structure is used, when water leaks from the pipe connectors 211 on both sides of the pipe connection housing 212, the connecting sleeve 1 will collect the leaked water. After the connecting sleeve 1 is full of water, the water will leak downward from the position of the limiting ring 207, and the leaked water will enter the second groove 202 and flow into the first groove 2. Since a water battery 201 is provided in the first groove 2, the water battery 201 will generate electricity after contacting water, thereby starting the solenoid valve 205. After the solenoid valve 205 is opened, the gas in the gas tank 204 will directly pass through the hose 206 and enter the annular sealing airbag 210 in the limiting ring 207, so that The annular sealing airbag 210 expands rapidly, clamping and sealing the pipe and the limiting ring 207, thereby preventing water from flowing out. After the annular sealing airbag 210 in the limiting ring 207 is filled with air, the gas will be input into the annular sealing airbag 210 in the pipe connector 211. The annular sealing airbag 210 in the pipe connector 211 is used to seal the position of the pipe connection, thereby achieving a double sealing effect. The arc-shaped support plate 3 is set on both sides of the connecting sleeve 1 to protect the top of the pipes on both sides. When the soil above sinks and collapses, the arc-shaped support plate 3 can be used for support to prevent the pipe from being directly subjected to pressure.
