Description

Technical Field

[0001] This invention relates to the field of tunnel drainage engineering technology, and in particular to a scale inhibition and prevention device for drainage pipelines in water conservancy tunnels. Background Technology

[0002] Drainage pipelines in hydraulic tunnels are underground drainage systems used to collect and discharge seepage, rainwater, or sewage in hydraulic tunnels. They are mainly formed by interwoven drainage pipes to create a drainage network. However, over time, due to the high calcium and magnesium ions in the seepage water from the tunnels, scale easily forms on the inner walls of the pipes. Thick scale buildup can reduce the inner diameter of the pipes, causing blockages and affecting the drainage performance of the hydraulic tunnels. Therefore, scale inhibitors and scale prevention devices are needed to reduce scale formation.

[0003] A search revealed a scale-inhibiting device and method for a tunnel drainage system published in Chinese Patent No. CN112744932A. The proposed scale-inhibiting device and method can inhibit scale buildup in the vertical and horizontal pipes of the tunnel drainage system, thereby preventing scale buildup from clogging the tunnel drainage pipes. In addition, it can eliminate or reduce the adverse effects of the discharged water on the surrounding environment.

[0004] However, in application, due to the high calcium and magnesium ions in the seepage water of water conservancy tunnels, it is difficult to effectively prevent and control the formation of calcium and magnesium ion scale in drainage by simply adding scale inhibitors. Scale formation will also occur after long-term use. Moreover, after scaling, it will adhere to the inner wall of the pipe. Furthermore, although the water is physically filtered through a filter screen at the water inlet during drainage of water conservancy tunnels, fine sand or solid particles can still enter the pipe, form sediment, and adhere to the inner wall of the drainage pipe, thus causing blockage of drainage. In view of this, this application is made. Summary of the Invention

[0005] To overcome the technical defects of the existing technology, the present invention provides a scale inhibition and prevention device for drainage pipelines in water conservancy tunnels, which has the effect of multi-effect scale inhibition and prevention, and has the technical feature of using a rushing flow to flush the inner wall of the pipeline to reduce the adhesion of impurities during use.

[0006] The technical solution adopted in this invention is: a scale inhibition and prevention device for drainage pipelines in water conservancy tunnels, comprising a fixing assembly. The fixing assembly consists of a fixing ring and clamping members arranged in an array on the outside of the fixing ring, used to install the entire assembly in the tunnel drainage pipeline. The clamping members consist of a sleeve, a T-shaped extension rod, and a fixing screw. The sleeve is fixed to the fixing ring, the extension rod is inserted into one side of the sleeve, and the fixing screw is threaded onto the sleeve, with one end extending into the inside of the sleeve and pressing against the extension rod. During fixing, the entire assembly is installed at the interface of the external pipeline. During installation, adjustments are made... The length of the extension rod inserted into the sleeve is such that the circumferentially distributed clamping members are all pressed against the inner wall of the pipe, thus fixing the fixing ring. A fixing frame is fixedly installed on the inner side of the fixing ring, and a micro-current anti-scaling generator is fixedly installed on one side of the fixing frame. The micro-current anti-scaling generator releases a small current to change the electric field environment of calcium and magnesium ions in the water, causing them to form loose aragonite crystals rather than hard calcite scale, thereby reducing scale adhesion to the inner wall of the pipe. A servo motor is fixedly installed on one side of the inner side of the fixing ring to drive the flow guiding and flushing assembly, causing the flow guiding and flushing assembly to rotate on the fixing ring.

[0007] The power generation component includes a generator and a first impeller. A first rotating shaft is fixedly mounted on one side of the first impeller and is rotatably mounted in the middle position of the fixed frame. The generator is fixedly mounted on one side of the fixed frame. One end of the first rotating shaft is fixedly connected to the drive end of the generator. When water flows inside the drainage pipe, the power of the flowing water drives the first impeller, which in turn drives the generator through the first rotating shaft to generate electrical energy to power the micro-current anti-scaling generator.

[0008] A slow-release agent component is fixedly installed on the water-facing side of the mounting bracket. The slow-release agent component includes a perforated box arranged in an array and containing a scale inhibitor. The scale inhibitor inside the perforated box is a solid scale inhibitor, including but not limited to one of organophosphorus scale inhibitors, polycarboxylic acid scale inhibitors, and FOF scale inhibitors, used to inhibit the scaling of calcium and magnesium ions in water.

[0009] A flow guiding and flushing assembly is rotatably mounted on the fixed ring, and the servo motor drives the flow guiding and flushing assembly to guide the water inside the drainage pipe, forming a turbulent flow state to flush the inner wall of the drainage pipe. The servo motor adjusts the flow guiding direction of the flow guiding and flushing assembly so that the turbulent flow position inside the drainage pipe is different, thereby achieving the effect of flushing different positions of the inner wall of the drainage pipe.

[0010] To improve the scale inhibition and prevention effect inside the water body, the present invention improves the fixed ring by making one side of the inside cavity, and fixing the nozzles for spraying liquid scale inhibitor in a circumferential array on the water-facing side of the fixed ring. A connecting threaded pipe is fixedly installed above the fixed ring, and a steel wire hose is threaded to the connecting threaded pipe. The connecting threaded pipe and the nozzles are both connected to the cavity inside the fixed ring.

[0011] To facilitate the control of electrical components and the monitoring of water bodies, the present invention improves upon this invention by fixing a control box containing a built-in wireless communication module, a battery, and a circuit board inside the fixing ring on the side opposite to the servo motor. A water quality monitoring sensor is fixedly installed on the water-facing side of the clamping member. The generator, the servo motor, the micro-current anti-scaling generator, and the water quality monitoring sensor are all electrically connected to the control box.

[0012] To facilitate the rotation of the flow guiding and flushing assembly on the fixed ring and adjust the position of flushing the inside of the drainage pipe, the present invention improves the fixed ring by providing a slide rail on one side of the outer ring. The flow guiding and flushing assembly is slidably mounted on the slide rail, and a drive gear is fixedly mounted on the output end of the servo motor. The drive gear meshes with the flow guiding and flushing assembly.

[0013] To facilitate the installation of the power generation components and the fixing ring, the present invention improves the installation by providing a first shaft hole in the middle of the fixing frame, rotatably mounting the first shaft on the first shaft hole, and fixing a rubber anti-slip pad on the outer side of the clamping member.

[0014] To improve the contact effect between the scale inhibitor inside the hollow box and the water, the present invention improves the agent slow-release component by further including a mounting bracket. The mounting bracket is fixedly connected to the fixed bracket. A second shaft hole is opened in the middle of one side of the mounting bracket. A second rotating shaft is rotatably installed inside the second shaft hole, and a second impeller is fixedly installed at one end of the second rotating shaft to drive the hollow box to rotate.

[0015] To facilitate the addition of scale inhibitor inside the hollow box, the present invention improves upon this invention by fixing a retainer on the second rotating shaft on the backwater side of the second impeller, with threaded rings fixedly mounted in a circumferential array on the retainer, and a threaded cap fixedly mounted on one side of the hollow box, the threaded cap being threadedly connected to the threaded rings.

[0016] To facilitate adjustment of the turbulent flow position, the present invention improves the flow guiding and flushing assembly by including a rotating ring, the rotating ring being rotatably mounted on the backwater side of the fixed ring, connecting plates being symmetrically fixedly mounted on the rotating ring, a fixed shaft being fixedly mounted between the connecting plates, and a flow guide plate being obliquely fixedly mounted on the fixed shaft.

[0017] To improve the stability of the connection between the rotating ring and the fixed ring, the present invention improves the method by fixing a slip ring on one side of the rotating ring, the slip ring being slidably connected to the slide rail, and the rotating ring having teeth fixedly installed in a circumferential array inside, the drive gear meshing with the teeth to drive the rotating ring to rotate on the fixed ring.

[0018] To improve the turbulent flow effect when flushing the inner wall of the drainage pipe, the present invention improves the method by symmetrically fixing guide strips on the lower inclined surface of the guide plate, with the ends of the two guide strips close together to form an open V-shaped structure.

[0019] The beneficial effects of this invention are: 1. This invention utilizes a first impeller and a second impeller to achieve self-driving by leveraging the power of water flow inside the pipe. This not only increases the contact range between the scale inhibitor filled in the hollow box and the water, but also generates electrical energy. Through a micro-current scale generator, it further inhibits calcium and magnesium ions in the water, improving the scale inhibition and prevention effect and reducing the maintenance cycle.

[0020] 2. This invention uses a water quality monitoring sensor to detect the water quality in the water body, and supplies liquid scale inhibitors according to the water quality. The liquid is sprayed out through a nozzle, and together with the scale inhibitor and a micro-current scale generator, it forms a multi-layer scale inhibition and prevention effect, effectively inhibiting and preventing scale in water with high calcium and magnesium ion content in drainage pipes of water conservancy tunnels.

[0021] 3. This invention uses a rotatable flow guiding and flushing component to guide the water inside the pipe, creating a turbulent flow near the inner wall of the pipe, thereby flushing the inner wall of the pipe and reducing the adhesion of solid impurities in the water to the inner wall of the pipe.

[0024] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-8 As shown, this embodiment provides a scale inhibition and anti-scaling device for drainage pipelines in water conservancy tunnels, including a fixing component 1. The fixing component 1 consists of a fixing ring 101 and clamping members 102 arranged in an array on the outside of the fixing ring 101, used to install the entire device in the tunnel drainage pipeline. The clamping member 102 consists of a sleeve, a T-shaped extension rod, and a fixing screw. The sleeve is fixed to the fixing ring 101, the extension rod is inserted into one side of the sleeve, and the fixing screw is threaded onto the sleeve, with one end of the fixing screw extending into the inside of the sleeve and pressing against the extension rod. During fixing, the entire device is installed at the interface position of the external pipeline, and during installation, the extension rod is adjusted by inserting it into the external pipe. The length of the sleeve ensures that the circumferentially distributed clamping members 102 are pressed against the inner wall of the pipe, thus fixing the fixing ring 101. A fixing bracket 103 is fixedly installed on the inner side of the fixing ring 101, and a micro-current anti-scaling generator 104 is fixedly installed on one side of the fixing bracket 103. The micro-current anti-scaling generator 104 releases a micro-current to change the electric field environment of calcium and magnesium ions in the water, causing them to form loose aragonite crystals instead of hard calcite scale, thereby reducing scale adhesion to the inner wall of the pipe. A servo motor 105 is fixedly installed on one side of the inner side of the fixing ring 101 to drive the rotating ring 401 and adjust its position when flushing the inner wall of the pipe.

[0025] The power generation component 2 includes a generator 201 and a first impeller 202. A first rotating shaft 203 is fixedly installed on one side of the first impeller 202, and the first rotating shaft 203 is rotatably installed in the middle position of the fixed frame 103. The generator 201 is fixedly installed on one side of the fixed frame 103. One end of the first rotating shaft 203 is fixedly connected to the drive end of the generator 201. By utilizing the water flow impact inside the drainage pipe, the first impeller 202 drives the first rotating shaft 203 to rotate, thereby driving the generator 201 to generate electrical energy, achieving a self-driving effect without the need for an external power source, reducing maintenance cycles, and achieving energy-saving and environmentally friendly effects.

[0026] The slow-release agent component 3 is fixedly installed on the water-facing side of the mounting bracket 103. The slow-release agent component 3 includes a perforated box 301 arranged in an array and containing scale inhibitor. The scale inhibitor inside the perforated box 301 is a solid scale inhibitor, including but not limited to one of organophosphorus series scale inhibitors, polycarboxylic acid scale inhibitors, and FOF method Oufu scale inhibitors, used to inhibit the scaling of calcium and magnesium ions in water. The perforated box 301 facilitates the contact between the scale inhibitor and the water, thereby improving the scale inhibition effect.

[0027] The flow guiding and flushing component 4 is rotatably mounted on the fixed ring 101, and the servo motor 105 drives the flow guiding and flushing component 4 to guide the water inside the drainage pipe, forming a turbulent flow state to flush the inner wall of the drainage pipe. During flushing, the servo motor 105 adjusts the direction of the turbulent flow to improve the coverage of the flushing of the inner wall of the drainage pipe and reduce the sedimentation of solid impurities in the water that adhere to the inner wall of the drainage pipe, thus affecting drainage use.

[0028] One side of the fixed ring 101 is hollow, and nozzles 106 for spraying liquid scale inhibitor are fixedly installed in a circumferential array on the water-facing side of the fixed ring 101. A connecting threaded pipe 107 is fixedly installed above the fixed ring 101, and a steel wire hose 108 is threaded onto the connecting threaded pipe 107. Both the connecting threaded pipe 107 and the nozzles 106 are connected to the hollow cavity inside the fixed ring 101. During installation, the need for installing the steel wire hose 108 is determined based on the water quality of the drainage from the water conservancy tunnel. When the steel wire hose 108 is not installed, the connecting threaded pipe 107 is sealed with an external plug. When the steel wire hose 108 is installed, the other end of the steel wire hose 108 is passed through the drainage pipe and extended to the outside of the drainage pipe for easy access later. Liquid scale inhibitor is added periodically. During addition, an external pressurizer supplies the liquid scale inhibitor into the cavity inside the fixing ring 101 through a steel wire hose 108, and sprays it out through the nozzle 106, allowing the liquid scale inhibitor to mix with the water and improve the scale inhibition effect. Inside the fixing ring 101, on the side opposite to the servo motor 105, a control box 109 with a built-in wireless communication module, battery, and circuit board is fixedly installed. A water quality monitoring sensor 1010 is fixedly installed on the water-facing side of the clamping member 102 to detect the water quality inside the drainage pipe. The water quality monitoring sensor 1010 can be a water hardness sensor, a calcium ion sensor, or a magnesium ion sensor. Its principle is based on electrochemical technology, reflecting the calcium and magnesium ion concentration in the water by measuring the calcium and magnesium ion concentration. When the calcium and magnesium ion content in the water is high, liquid scale inhibitor can be sprayed through nozzle 106 to achieve scale prevention. Generator 201, servo motor 105, micro-current scale generator 104 and water quality monitoring sensor 1010 are all electrically connected to control box 109. The electrical energy generated by generator 201 is stored in the battery inside control box 109, and the battery supplies power to other electrical components. Water quality monitoring sensor 1010 transmits the monitoring results to an external terminal through the built-in wireless communication module of control box 109 for remote monitoring. A slide rail 1011 is provided on one side of the outer ring of fixed ring 101. The flow guiding and flushing assembly 4 is slidably installed on slide rail 1011, and a drive gear is fixedly installed at the output end of servo motor 105. 1012, the drive gear 1012 meshes with the flow guiding and flushing assembly 4. When the servo motor 105 drives the drive gear 1012 to rotate, the flow guiding and flushing assembly 4 rotates along the slide 1011 on the fixed ring 101, adjusting the flow direction and flushing different positions on the inner wall of the drainage pipe. The fixed frame 103 has a first shaft hole 1013 in the middle position. The first rotating shaft 203 is rotatably installed on the first shaft hole 1013, which facilitates the first impeller 202 to drive the first rotating shaft 203 to rotate on the first shaft hole 1013. A rubber anti-slip pad 1014 is fixedly installed on the outside of the clamping member 102. When the whole is fixed inside the drainage pipe by the clamping member 102, the rubber anti-slip pad 1014 is pressed against the inner wall of the drainage pipe, improving the stability of the installation.

[0029] The drug release assembly 3 also includes a mounting bracket 302, which is fixedly connected to the fixing bracket 103. A second shaft hole 303 is provided at the middle of one side of the mounting bracket 302. A second rotating shaft 304 is rotatably mounted inside the second shaft hole 303, and a second impeller 305 is fixedly mounted at one end of the second rotating shaft 304 to drive the hollow box 301 to rotate. A retainer 306 is fixedly mounted on the second rotating shaft 304 on the back side of the second impeller 305. Threaded rings 307 are fixedly mounted in a circumferential array on the retainer 306. A threaded cap 3 is fixedly mounted on one side of the hollow box 301. 08. The threaded cap 308 is threadedly connected to the threaded ring 307. When storing the scale inhibitor, the slow-release solid scale inhibitor is first placed into the hollow box 301, and the hollow box 301 is installed on the threaded ring 307 through the threaded cap 308, so that the hollow box 301 is fixedly connected to the retainer 306. During use, the water flow impacts the second impeller 305, causing the second rotating shaft 304 to rotate in the second shaft hole 303 on the mounting bracket 302, which in turn drives the retainer 306 to rotate, causing the hollow box 301 to rotate, thereby improving the contact effect between the water and the scale inhibitor inside the hollow box 301.

[0030] The flow guiding and flushing assembly 4 includes a rotating ring 401, which is rotatably mounted on the backwater side of a fixed ring 101. Connecting plates 402 are symmetrically fixedly mounted on the rotating ring 401, and a fixed shaft 403 is fixedly mounted between the connecting plates 402. A flow guide plate 404 is obliquely fixedly mounted on the fixed shaft 403. The flow guide plate 404 cuts the water flow inside the drainage pipe, causing the water to flow along the flow guide plate 404. One end of the flow guide plate 404 is close to the inner wall of the drainage pipe. When the cut water flows along the flow guide plate 404, the flow velocity increases due to the smaller gap when it passes the side of the flow guide plate 404 close to the inner wall of the drainage pipe, creating a flushing effect on the inner wall of the pipe. Furthermore, as the rotating ring 401 rotates on the fixed ring 101, the flushing position changes, improving the coverage of the flushing on the inner wall of the pipe and preventing solid impurities in the water from adhering to the inner wall of the pipe. The water flow above the flow guide plate 404 also experiences a flow effect due to the smaller gap. The expansion of the flow creates turbulence, improving the mixing effect of the scale inhibitor with the water and further enhancing the scale inhibition and prevention effect. A slip ring 405 is fixedly installed on one side of the rotating ring 401, and the slip ring 405 is slidably connected to the slide rail 1011. The inside of the rotating ring 401 is fixedly installed with teeth 406 in a circumferential array. The drive gear 1012 meshes with the teeth 406 to drive the rotating ring 401 to rotate on the fixed ring 101, which in turn drives the drive gear 1012 via the servo motor 105. When 012 rotates, the rotating ring 401 rotates on the slide rail 1011 through the slip ring 405, adjusting the flushing position of the drainage pipe. The guide strips 407 are symmetrically fixed on the lower inclined surface of the guide plate 404. The ends of the two guide strips 407 are brought together to form an open V-shaped structure. Through the guide strips 407, the water flow passing under the guide plate 404 is further guided, reducing the gap on the outlet side, further increasing the turbulence force, and improving the flushing effect.
