Description

Technical Field

[0001] This utility model relates to the field of water hammer eliminators, specifically a water hammer eliminator for long-distance sewage pressure pipeline projects. Background Technology

[0002] In long-distance sewage pressure pipeline projects, water hammer can easily impact the pipeline system and affect the stability of the project operation. Therefore, relevant equipment is needed to eliminate the impact of water hammer and ensure pipeline safety.

[0003] In the existing technology, water hammer elimination equipment used in long-distance sewage pressure pipeline projects has the following shortcomings: it lacks a device for real-time monitoring of the surrounding sewage pressure, making it difficult to accurately determine the occurrence of water hammer and take timely countermeasures; during the sliding process of the piston assembly, the bottom and the inner cavity of the assembly pipe are easily hindered by the accumulation of sludge in the sewage, which may also interfere with the accuracy of pressure monitoring. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water hammer eliminator for long-distance sewage pressure pipeline projects, which solves the above-mentioned problems of lacking a device for real-time monitoring of surrounding sewage pressure, making it difficult to accurately determine the occurrence of water hammer and take timely countermeasures; and the technical problems that the bottom and inner cavity of the piston assembly are easily hindered by the accumulation of sludge in the sewage during the sliding process, while the sludge may interfere with the accuracy of pressure monitoring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water hammer eliminator for long-distance sewage pressure pipeline engineering, comprising: a pipe body, an assembly pipe, a drain valve, and a cylinder. The cylinder is assembled at the top of the inner cavity of the assembly pipe. The drain valve is connected to the assembly pipe, and the assembly pipe is connected to the pipe body. A piston assembly is connected to the output end of the cylinder. A pressure sensor is connected to the outside of the piston assembly, and a sludge removal mechanism is provided at the bottom of the piston assembly.

[0006] The cylinder can drive the piston assembly to slide up and down along the inner cavity of the assembly pipe. The pressure sensor monitors the sewage pressure around the piston assembly in real time and transmits the pressure signal to the control module, providing a basis for water hammer judgment and subsequent actions. The sludge removal mechanism can remove the sludge accumulation at the bottom of the piston assembly and the inner cavity of the assembly pipe, avoiding the sludge from affecting the sliding flexibility of the piston assembly and the monitoring accuracy of the pressure sensor.

[0007] The mud removal mechanism includes an air inlet pipe, the bottom of which is connected to a bend pipe, the other end of which is connected to an air bladder, the outside of which is connected to a piston assembly, the other end of which is connected to a push plate, the top of which is slidably connected to the bottom of the piston assembly, and a guide block is provided on the top of which is slidably connected to the bottom of the piston assembly.

[0008] When the piston assembly is driven by the cylinder, it works with the assembly pipe to generate an air source. The air source delivers gas to the bend pipe through the intake pipe. The gas enters the air bladder through the bend pipe, causing the air bladder to inflate. The inflated air bladder pushes the push plate to slide along the bottom of the piston assembly. The guide block can limit the sliding direction of the push plate to prevent the push plate from deviating and ensure that the push plate can stably clean the sludge at the bottom of the piston assembly, preventing the sludge from affecting the piston assembly and pressure sensor. At the same time, it can also connect an external air pump to the assembly pipe for air supply.

[0009] Preferably, the outside of the pipe body is uniformly provided with reinforcing ribs, and both ends of the pipe body are fitted with flanges.

[0010] Reinforcing ribs enhance the structural strength and pressure resistance of the pipe body, effectively resisting the sewage pressure in long-distance sewage pressure pipelines and the impact of the external environment. This prevents the pipe body from deforming or cracking due to excessive pressure or impact, extending the service life of the pipe body. Flanges facilitate the connection of the pipe body with other pipe sections or equipment in long-distance sewage pressure pipelines, and the connection provides strong sealing, preventing sewage leakage from the connection point. They also facilitate subsequent installation, disassembly, and maintenance operations.

[0011] Preferably, the drain valve is externally connected to a control valve, and a sealing gasket is provided between the drain valve and the assembly pipe.

[0012] The control valve controls the opening / closing status of the drain valve and the drain flow rate. When the pressure sensor detects that the pressure in the pipeline exceeds the set threshold, the control module controls the control valve to open the drain valve, thereby reducing the sewage pressure in the pipe body and assembly pipe and eliminating water hammer. The sealing gasket fills the gap between the drain valve and the assembly pipe, enhances the sealing of the connection between the two, prevents sewage from leaking from the connection, avoids sewage overflow and environmental pollution, and ensures stable pressure in the pipeline, ensuring that the water hammer elimination function is properly implemented.

[0013] Preferably, a control module is provided at the upper end of the assembly tube, and a power module is provided inside the control module.

[0014] The control module is the core of the water hammer eliminator. It receives pressure data from the pressure sensor and uses a built-in program to determine if water hammer has occurred in the pipeline. If water hammer occurs, it promptly sends action commands to components such as cylinders and control valves to coordinate the elimination of water hammer. The power module provides continuous and stable power to the control module, pressure sensor, cylinders, and other electrical components, ensuring that each component operates without interruption during long-distance sewage pressure pipeline operation. This prevents the water hammer eliminator from failing due to power outages and ensures pipeline safety.

[0015] Preferably, the inner cavity of the piston assembly is provided with a curved groove, which is connected to a bent pipe, and a sealing sleeve is connected between the curved groove and the bent pipe.

[0016] The curved groove provides a suitable installation space for the bend, ensuring that the bend can be stably connected to the piston assembly without affecting the normal sliding of the piston assembly; the sealing sleeve can block gas leakage at the connection between the curved groove and the bend, ensuring that all the gas delivered by the air inlet pipe can enter the air bladder, allowing the air bladder to expand normally and push the push plate. At the same time, it can also prevent sewage and sludge from entering the curved groove and the bend, avoiding pipe blockage and affecting the working efficiency of the sludge removal mechanism.

[0017] Preferably, the bottom of the intake pipe is provided with a bracket, which is connected to the bottom of the piston assembly. Both the upper and lower ends of the piston assembly are provided with rubber pads, and the inner cavity of the piston assembly is embedded with a guide plate, which is slidably connected to the assembly pipe.

[0018] The rubber pads cushion the impact of the piston assembly against the top and bottom of the assembly tube when the piston assembly slides up and down, reducing component wear and extending the service life of the piston assembly and assembly tube. The sliding fit between the guide plate and the assembly tube restricts the movement trajectory of the piston assembly, preventing deviation and jamming when the piston assembly slides, and ensuring that the piston assembly can move smoothly to cooperate with pressure regulation and water hammer elimination operations.

[0019] Compared with the prior art, this utility model provides a water hammer eliminator for long-distance sewage pressure pipeline projects, which has the following beneficial effects:

[0020] This water hammer eliminator, used in long-distance sewage pressure pipeline projects, uses a cylinder to drive a piston assembly to slide up and down along the inner cavity of the assembly pipe. An external pressure sensor monitors the surrounding sewage pressure in real time and transmits the pressure signal to the control module. This provides a reliable basis for accurate water hammer assessment and subsequent response actions, helping to take timely measures to eliminate the impact of water hammer and ensuring the stable operation of long-distance sewage pressure pipeline projects. The sludge removal mechanism at the bottom of the piston assembly, when driven by the cylinder, works with the assembly pipe to generate an air source. The air source is delivered through the air inlet pipe to the bend and then into the air bladder, causing the air bladder to inflate and push the push plate to slide along the bottom of the piston assembly. The guide block at the top of the push plate effectively limits the sliding direction of the push plate and prevents deviation, thereby stably removing sludge buildup at the bottom of the piston assembly and inside the assembly pipe. This prevents sludge from hindering the sliding flexibility of the piston assembly and also avoids sludge interfering with the monitoring accuracy of the pressure sensor, further ensuring that all components of the water hammer eliminator maintain good working performance.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a technical solution, please refer to Figure 1 and Figure 2 A water hammer eliminator for long-distance sewage pressure pipeline engineering includes: a pipe body 1, an assembly pipe 2, a drain valve 3, and a cylinder 4. The cylinder 4 is assembled at the top of the inner cavity of the assembly pipe 2. The drain valve 3 is connected to the assembly pipe 2. The assembly pipe 2 is connected to the pipe body 1. The output end of the cylinder 4 is connected to a piston assembly 41. A pressure sensor 42 is connected to the outside of the piston assembly 41. A sludge removal mechanism 5 is provided at the bottom of the piston assembly 41.

[0029] The cylinder 4 can drive the piston assembly 41 to slide up and down along the inner cavity of the assembly pipe 2. The pressure sensor 42 monitors the sewage pressure around the piston assembly 41 in real time and transmits the pressure signal to the control module 21 to provide a basis for water hammer judgment and subsequent actions. The sludge removal mechanism 5 can remove the sludge accumulation at the bottom of the piston assembly 41 and the inner cavity of the assembly pipe 2 to avoid the sludge affecting the sliding flexibility of the piston assembly 41 and the monitoring accuracy of the pressure sensor 42.

[0030] Please see Figure 3 and Figure 4 The mud removal mechanism 5 includes an air inlet pipe 51, the bottom of which is connected to a bend pipe 52, and the other end of the bend pipe 52 is connected to an air bladder 53. The outside of the air bladder 53 is connected to the piston assembly 41, and the other end of the air bladder 53 is connected to a push plate 54. The top of the push plate 54 is slidably connected to the bottom of the piston assembly 41, and a guide block 55 is provided on the top of the push plate 54. The guide block 55 is slidably connected to the bottom of the piston assembly 41.

[0031] Please see Figure 5When the piston assembly 41 is driven by the cylinder 4, it works with the assembly pipe 2 to generate an air source. The air source delivers gas to the bend pipe 52 through the air inlet pipe 51. The gas enters the air bladder 53 through the bend pipe 52, causing the air bladder 53 to inflate. The inflated air bladder 53 pushes the push plate 54 to slide along the bottom of the piston assembly 41. The guide block 55 can limit the sliding direction of the push plate 54 to prevent the push plate 54 from deviating, ensuring that the push plate 54 can stably clean the sludge at the bottom of the piston assembly 41, preventing the sludge from affecting the piston assembly 41 and the pressure sensor 42. At the same time, it can also connect the external air pump to the assembly pipe 2 to supply air.

[0032] The pipe body 1 is uniformly provided with reinforcing ribs 11 on its exterior. Both ends of the pipe body 1 are fitted with flanges 12. The reinforcing ribs 11 can enhance the structural strength and pressure resistance of the pipe body 1, effectively resist the sewage pressure in the long-distance sewage pressure pipeline and the impact of the external environment, prevent the pipe body 1 from deforming or cracking due to excessive pressure or impact, and extend the service life of the pipe body 1. The flanges 12 facilitate the connection of the pipe body 1 with other pipe sections or equipment in the long-distance sewage pressure pipeline, and the connection has strong sealing performance, which can prevent sewage from leaking from the connection point, and at the same time facilitates the subsequent installation, disassembly and maintenance operations.

[0033] The drain valve 3 is externally connected to a control valve 31, and a sealing gasket is provided between the drain valve 3 and the assembly pipe 2.

[0034] The control valve 31 can control the opening / closing state of the drain valve 3 and the drain flow rate. When the pressure sensor 42 detects that the pressure in the pipeline exceeds the set threshold, the control module 21 will control the control valve 31 to open the drain valve 3, thereby reducing the sewage pressure in the pipe body 1 and the assembly pipe 2 by draining water, thus eliminating water hammer. The sealing gasket can fill the gap between the drain valve 3 and the assembly pipe 2, enhance the sealing of the connection between the two, prevent sewage from leaking from the connection, avoid sewage overflow and polluting the environment, and at the same time ensure the stability of the pressure in the pipeline, ensuring that the water hammer elimination function is realized normally.

[0035] A control module 21 is provided at the upper end of the assembly tube 2, and a power module is provided inside the control module 21.

[0036] The control module 21 is the core of the water hammer eliminator. It can receive pressure data transmitted by the pressure sensor 42 and determine whether water hammer occurs in the pipeline through the built-in program. If water hammer occurs, it will send action commands to components such as the cylinder 4 and the control valve 31 in a timely manner to coordinate the components to eliminate water hammer. The power module can provide continuous and stable power to the control module 21, pressure sensor 42, cylinder 4 and other electrical components to ensure that the components do not work interrupted during the operation of long-distance sewage pressure pipelines, avoid the failure of the water hammer eliminator due to power failure, and ensure pipeline safety.

[0037] The piston assembly 41 has a curved groove in its inner cavity, which is connected to the bent pipe 52, and a sealing sleeve is connected between the curved groove and the bent pipe 52.

[0038] The curved groove provides a suitable installation space for the bend 52, ensuring that the bend 52 can be stably connected to the piston assembly 41 without affecting the normal sliding of the piston assembly 41; the sealing sleeve can block gas leakage at the connection between the curved groove and the bend 52, ensuring that all the gas delivered by the air inlet pipe 51 can enter the air bag 53, so that the air bag 53 can expand normally to push the push plate 54. At the same time, it can also prevent sewage and sludge from entering the curved groove and the interior of the bend 52, avoiding pipe blockage and affecting the working efficiency of the sludge removal mechanism 5.

[0039] A bracket is provided at the bottom of the intake pipe 51, which is connected to the bottom of the piston assembly 41. Rubber pads are provided at both the upper and lower ends of the piston assembly 41. A guide plate is embedded in the inner cavity of the piston assembly 41, and the guide plate is slidably connected to the assembly pipe 2.

[0040] The rubber pad can buffer the collision and impact between the piston assembly 41 and the top and bottom of the assembly tube 2 when the piston assembly 41 slides up and down, reduce component wear, and extend the service life of the piston assembly 41 and the assembly tube 2; the sliding cooperation between the guide plate and the assembly tube 2 can limit the movement trajectory of the piston assembly 41, prevent the piston assembly 41 from deviating or jamming when sliding, and ensure that the piston assembly 41 can move smoothly to cooperate with pressure regulation and water hammer elimination operations.
