Description

Technical Field

[0001] This utility model relates to a sedimentation device for water supply networks, specifically in the field of water supply networks. Background Technology

[0002] In existing technology, the pipeline system for supplying and distributing water to users in water supply projects is also called the water supply network. It includes water transmission pipelines, water distribution networks, booster pump stations, water towers, water tanks, and other network ancillary facilities. The pipelines from the water source to the water plant only serve the function of water transmission and are called the water transmission network. The pipelines from the water plant are called the water distribution network. The pipelines in the water distribution network that mainly serve the function of water transmission are called main pipes. The pipelines that branch off from the main pipes and serve the function of water distribution are called branch pipes. The pipelines that connect to users from the branch pipes are called user branch pipes.

[0003] According to the existing authorized announcement number: CN208441160U, the patent title is: A sedimentation pipe for water supply network. This patent includes a sedimentation pipe with an inlet at one end and an outlet and a sand discharge port at the other end. The outlet is located above the sand discharge port, which is equipped with a sand discharge valve. The diameter of the sedimentation pipe is larger than the diameters of the inlet and outlet, and it has a certain length. Water containing silt and sand in the sedimentation pipe has a reduced flow velocity, and the silt and sand in the water naturally settles and accumulates at the bottom of the sedimentation pipe due to gravity, and is then discharged through the sand discharge port. It has a good effect on removing silt and sand, consumes little water, and does not affect normal water supply. It can reduce the impact of silt and sand and other debris on pipes, valves, water meters, etc.

[0004] However, although the patent can collect and discharge sediment, the discharge of sediment still requires the impact force of water flow to flush it out, resulting in a poor sediment cleaning effect. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sedimentation device for water supply network to solve the problems mentioned in the background art. This utility model facilitates the discharge of sediment and the sediment discharge effect is better.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a sedimentation device for a water supply network, comprising a pipe body, a cleaning mechanism provided on the outer surface of the pipe body, the cleaning mechanism including a sedimentation pipe connected to the bottom of the outer surface of the pipe body, a partition plate fixedly connected to the inner wall of the sedimentation pipe, a first bearing embedded inside the partition plate, a positive and negative spiral push rod fixedly connected to the inner ring of the first bearing, the opposite ends of the positive and negative spiral push rods both penetrating the sedimentation pipe and extending to the outside of the sedimentation pipe, a servo motor fixedly connected to the right side of the sedimentation pipe, the output shaft of the servo motor fixedly connected to the right end of the positive and negative spiral push rods, sand discharge pipes connected to both ends of the sedimentation pipe, two fixing plates fixedly connected to the inner bottom wall of the pipe body, a fixing rod fixedly connected to the right side of the fixing plate, a filter plate fixedly connected to the right side of the fixing rod, and filter holes opened on the outer surface of the filter plate.

[0007] Furthermore, the right side of the pipe body is connected to a first connector, and the right side of the first connector is connected to a drain pipe. The first connector can connect the pipe body to the drain pipe, which facilitates the discharge of water inside the pipe body and also facilitates the installation and disassembly of the drain pipe, making it convenient to use.

[0008] Furthermore, a second connector is fixedly connected to the left side of the pipe body, and a water injection pipe is connected to the left side of the second connector. The second connector facilitates the connection of the water injection pipe, which facilitates the injection of water into the interior of the pipe body. It also facilitates the disassembly and installation of the water injection pipe, and facilitates the replacement and installation of this sedimentation device in the future.

[0009] Furthermore, each of the two sand discharge pipes is connected to a fixed pipe at its far ends. A valve is fitted on the outer surface of the fixed pipe. The fixed pipe can be used to divert the silt inside the sand discharge pipe, facilitating the discharge of silt. At the same time, the valve can limit the movement of the fixed pipe, preventing water and silt from being discharged from the inside of the sand discharge pipe during water flow, thus avoiding leakage.

[0010] Furthermore, a stabilizing plate is fixedly connected to the outer surface of the servo motor, and a stabilizing rod is fixedly connected to the left side of the stabilizing plate. The left end of the stabilizing rod is fixedly connected to the right side of the tube body. The stabilizing plate and the stabilizing rod can be used to further fix the servo motor, improve the stability of the servo motor during use, and effectively prevent the servo motor from shaking during use, thereby effectively preventing the servo motor from being affected by shaking.

[0011] Furthermore, a second bearing is embedded on the right side of the tube body. The output shaft of the servo motor passes through the second bearing and extends into the interior of the tube body. The outer surface of the output shaft of the servo motor is fixedly connected to the inner ring of the second bearing. This effectively prevents the output shaft of the servo motor from rubbing against the tube body, thereby preventing the output shaft of the servo motor from wearing due to friction and thus preventing the normal use of the servo motor from being affected by the wear of the output shaft.

[0012] Furthermore, two arc-shaped semi-rings are fixedly connected to the inner wall of the pipe. The arc-shaped semi-rings can guide the water flow, allowing the water to move closer to the drain pipe and the first connector, facilitating the discharge of the water.

[0013] Furthermore, an operation indicator plate is fixedly connected to the outer surface of the tube body, and a transparent observation window is fixedly embedded on the back of the sedimentation tube. The outer surface of the operation indicator plate is engraved with installation instructions. By reading the installation instructions on the operation indicator plate, the operator can quickly master the correct installation method and effectively avoid installation errors caused by incorrect installation methods.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses a servo motor to drive the forward and reverse spiral push rods to rotate. The forward and reverse spiral push rods push the sediment inside the sedimentation tube to the left and right sides of the sedimentation tube. Then the sediment is discharged from the sand discharge pipe and the fixed pipe, thereby realizing the cleaning operation of sediment. The whole system uses the forward and reverse spiral push rods to push and discharge sediment, realizing the automatic cleaning operation of sediment, and has a good cleaning effect.

[0016] 2. This utility model connects the pipe body to the drainage pipe via the first connector, facilitating the discharge of water from the pipe body and making the drainage pipe easy to install and disassemble. The fixed pipe allows for the diversion of sediment from the sand discharge pipe, facilitating its discharge. A valve limits the movement of the fixed pipe, preventing water and sediment from leaking out of the sand discharge pipe during water flow. The stabilizing plate and stabilizer further secure the servo motor, improving its stability during use and preventing wobbling that could affect its normal operation. Attached Figure Description

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] See Figure 1 - Figure 4 This embodiment proposes a sedimentation device for a water supply network, including a pipe body 1. A first connector 6 is connected to the right side of the pipe body 1, and a drain pipe 7 is connected to the right side of the first connector 6. The pipe body 1 and the drain pipe 7 can be connected through the first connector 6, which facilitates the discharge of water inside the pipe body 1 and facilitates the installation and disassembly of the drain pipe 7, making it convenient to use.

[0025] The left side of the pipe body 1 is fixedly connected to the second connector 4, and the left side of the second connector 4 is connected to the water injection pipe 3. The second connector 4 facilitates the connection of the water injection pipe 3, which facilitates the injection of water into the interior of the pipe body 1. It also facilitates the disassembly and installation of the water injection pipe 3, and facilitates the replacement and installation of this sedimentation device in the future.

[0026] Two arc-shaped semi-rings 207 are fixedly connected to the inner wall of the pipe body 1. The arc-shaped semi-rings 207 can guide the water flow, so that the water can move closer to the drain pipe 7 and the first joint 6, which facilitates the discharge of the water.

[0027] An operation indicator plate 5 is fixedly connected to the outer surface of the tube body 1, and a transparent observation window 11 is fixedly embedded on the back of the sedimentation tube 204. The outer surface of the operation indicator plate 5 is engraved with installation instructions. By reading the installation instructions on the operation indicator plate 5, the staff can quickly master the correct installation method and effectively avoid installation errors caused by incorrect installation methods.

[0028] Staff can observe the sediment inside the sedimentation tube 204 through the transparent observation window 11. When too much sediment settles, the cleaning mechanism 2 is activated to discharge the sediment, effectively preventing excessive sediment from clogging the tube 1 and thus avoiding affecting the normal use of the pipeline network.

[0029] A cleaning mechanism 2 is provided on the outer surface of the tube body 1. The cleaning mechanism 2 includes a sedimentation tube 204 connected to the bottom of the outer surface of the tube body 1. A partition 205 is fixedly connected to the inner wall of the sedimentation tube 204. A first bearing 2011 is embedded inside the partition 205. A positive and negative spiral push rod 2010 is fixedly connected to the inner ring of the first bearing 2011.

[0030] The 2010 reversible helical push rod is a helical push rod that moves in opposite directions from the center to both sides.

[0031] The opposite ends of the forward and reverse spiral push rods 2010, which are far apart from each other, both penetrate the sedimentation tube 204 and extend to the outside of the sedimentation tube 204. A servo motor 203 is fixedly connected to the right side of the sedimentation tube 204. A stabilizing plate 10 is fixedly connected to the outer surface of the servo motor 203. A stabilizing rod 9 is fixedly connected to the left side of the stabilizing plate 10. The left end of the stabilizing rod 9 is fixedly connected to the right side of the tube body 1. The stabilizing plate 10 and the stabilizing rod 9 can be used to further fix the servo motor 203, improve the stability of the servo motor 203 during use, and effectively prevent the servo motor 203 from shaking during use, thereby effectively preventing the servo motor 203 from being affected by shaking.

[0032] Servo motor 203 can control speed and has very accurate position. It can convert voltage signals into torque and speed to drive the controlled object. The rotor speed of servo motor 203 is controlled by the input signal and can respond quickly. In automatic control systems, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signals into angular displacement or angular velocity output on the motor shaft.

[0033] A second bearing 208 is embedded on the right side of the tube body 1. The output shaft of the servo motor 203 passes through the second bearing 208 and extends into the interior of the tube body 1. The outer surface of the output shaft of the servo motor 203 is fixedly connected to the inner ring of the second bearing 208. This effectively prevents the output shaft of the servo motor 203 from rubbing against the tube body 1, thereby effectively preventing the output shaft of the servo motor 203 from wearing due to friction, and thus preventing the normal use of the servo motor 203 from being affected by the wear of the output shaft.

[0034] In this application, the first bearing 2011 and the second bearing 208 are the same type of waterproof bearing. The waterproof bearing effectively prevents water leakage. The first bearing 2011 and the second bearing 208 improve the stability of the forward and reverse helical push rod 2010 during rotation, effectively preventing it from shaking.

[0035] The output shaft of the servo motor 203 is fixedly connected to the right end of the forward and reverse spiral push rod 2010. Both ends of the sedimentation pipe 204 are connected to the sand discharge pipe 201. The ends of the two sand discharge pipes 201 that are far apart from each other are connected to the fixed pipe 202. The outer surface of the fixed pipe 202 is fitted with a valve 8. The fixed pipe 202 can be used to drain the silt inside the sand discharge pipe 201, which facilitates the discharge of silt. At the same time, the valve 8 can limit the fixed pipe 202 to prevent water and silt from being discharged from the inside of the sand discharge pipe 201 during water flow, thus avoiding leakage.

[0036] Two fixing plates 2013 are fixedly connected to the inner bottom wall of the tube body 1. A fixing rod 2012 is fixedly connected to the right side of the fixing plate 2013. A filter plate 206 is fixedly connected to the right side of the fixing rod 2012. Filter holes 209 are opened on the outer surface of the filter plate 206.

[0037] When in use, water is injected into the interior of pipe 1 through water injection pipe 3. The sediment inside the water settles into the interior of sedimentation pipe 204 due to its own weight. When too much sediment settles, the servo motor 203 is connected to the municipal power supply. The servo motor 203 drives the forward and reverse spiral push rod 2010 to rotate. The forward and reverse spiral push rod 2010 pushes the sediment inside sedimentation pipe 204 to the left and right sides of sedimentation pipe 204. The staff opens valve 8, and then the sediment is discharged from sand discharge pipe 201 and fixed pipe 202, thereby realizing the cleaning operation of sediment.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
