Description

Technical Field

[0001] This invention relates to the field of vacuum drainage technology for dredged fill, and in particular to a zoned drainage control device for dredged fill in coastal areas. Background Technology

[0002] Vacuum drainage of dredged fill mainly involves setting up a drainage system (such as drainage boards, sand wells, etc.) in the dredged fill and laying a sealing membrane on the ground. A vacuum pump is used to extract the air under the sealing membrane, creating a vacuum negative pressure. Under the action of the vacuum negative pressure, the pore water in the soil is sucked out and discharged to the ground through the drainage system, thereby accelerating the drainage and consolidation of the soil. This method uses the pressure difference between atmospheric pressure and vacuum negative pressure as the driving force to push the water out of the soil. It can effectively reduce the soil moisture content and improve the foundation strength without the need to apply a large external load.

[0003] Most drainage control equipment uses a water-air separator, a vacuum system, and a drainage system to perform vacuum drainage, water-air separation, and drainage of the water-air separator. This process requires a relatively complex control system to control the vacuum system and the drainage system separately. In addition, during the vacuum adsorption and water-air separation process in the backfill area using a vacuum pump, some water droplets will inevitably enter the vacuum system due to the high airflow velocity generated by the vacuum pump. This not only affects the normal working efficiency of the vacuum system but also significantly reduces the service life of the vacuum pump.

[0004] This defect is mainly caused by the following reasons: Although the current drainage control equipment uses a water-air separator for preliminary water-air separation, there is a lack of an effective mechanism to prevent water droplets from being carried into the vacuum system by the high-speed airflow before the water-air mixture enters the vacuum pump. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a zoned drainage control device for coastal reclaimed soil, in view of the above-mentioned problems.

[0006] The technical solution adopted in this invention is: a zoned drainage control device for coastal reclaimed land, comprising: The base has a vacuum pump that provides the power for vacuum adsorption and an air compressor that provides high-pressure gas at the top. A water-air separator is located on the top of the base and has a first partition and a second partition inside. A shaft is rotatably provided between the first partition and the second partition, and a cavity is provided inside the shaft. A pneumatic assembly is located at the top of the first partition. The two ends of the pneumatic assembly are respectively connected to the input end of the vacuum pump and the top of the cavity of the shaft. The pneumatic assembly is connected to the shaft and can drive the shaft to rotate around its own axis under the action of airflow. The separation component is located below the second partition plate and is connected to the bottom of the cavity of the shaft. The input end of the separation component penetrates the side wall of the water-air separator to introduce the water-air mixture discharged from the backfill. The separation component is driven to rotate by the shaft and can discharge the water in the water-air mixture through its own output end to the lower cavity of the second partition plate under centrifugal force. The drainage component is located below the separation component and is connected to the output end of the air compressor. When the water level in the lower chamber of the second partition reaches the preset water level threshold, the drainage component can use high-pressure gas to discharge the water inside the chamber to the outside of the water-air separator.

[0007] By using the above-mentioned technical means, the airflow generated by the vacuum pump is used as a power source. The pneumatic components drive the shaft to rotate, and the shaft drives the separation components to move. Under centrifugal force, the water droplets in the water-air mixture discharged by the backfill are thrown against the inner wall of the water-air separation tank and stored in the chamber below the second partition, while the gas continues to flow upward, thereby improving the water-air separation efficiency and preventing liquid water from entering the vacuum pump.

[0008] In some embodiments, a communication component is further included. The sidewall of the shaft is provided with a plurality of first through holes spaced apart circumferentially. An air inlet pipe is connected to the first through hole of the shaft. The second partition is provided with a plurality of flow ports. The communication component is disposed on the second partition. The communication component can obtain the pressure information of the chamber below the second partition and control the opening and closing of the flow ports based on the pressure information, so that the gas in the chamber below the second partition can flow to the chamber between the first partition and the second partition.

[0009] In some embodiments, the communication component includes a solenoid valve, a pressure sensor, and a controller. The pressure sensor and the solenoid valve are both communicatively connected to the controller. A solenoid valve is provided at the flow port. A pressure sensor is provided through the second partition. The pressure sensor can obtain the air pressure information inside the chamber below the second partition. If the air pressure information is higher than the preset air pressure threshold inside the controller, the solenoid valve is controlled to block the flow port. If the air pressure information is lower than the preset air pressure threshold inside the controller, the solenoid valve is controlled to open the flow port.

[0010] In some embodiments, the communication component further includes a liquid level sensor, which is communicatively connected to the controller. The liquid level sensor is provided in the chamber below the second partition. The liquid level sensor can obtain the liquid level information inside the chamber below the second partition. If the liquid level information is higher than the preset water level threshold inside the controller, the drainage component is controlled to release high-pressure gas into the chamber below the second partition to drain the water outward.

[0011] In some embodiments, the bottom of the water-gas separator is provided with a drain pipe, and a pressure relief valve is installed on the drain pipe.

[0012] In some embodiments, the drainage assembly includes a fixed plate, a first connecting pipe, a second connecting pipe, a high-pressure tank, a positive pressure pipe, and a valve. The valve is communicatively connected to a controller. The inner wall of the water-air separator is provided with a plurality of fixed plates located below the first partition along the circumferential direction. A high-pressure tank is correspondingly installed on the fixed plate. The outer walls of the plurality of high-pressure tanks are connected to a first connecting pipe and a second connecting pipe arranged in a double ring. Both the first connecting pipe and the second connecting pipe are connected to the high-pressure tank. The first connecting pipe is connected to the output end of the air compressor via the positive pressure pipe. A valve is provided on the first connecting pipe or the second connecting pipe.

[0013] In some embodiments, the pneumatic assembly includes a housing, gears, a negative pressure pipe, and a tube. The housing is mounted on the top of the first partition, and a first connecting seat is connected to the bottom of the first partition via multiple rods. The rotating shaft is rotatably connected inside the first connecting seat, and the cavity of the first connecting seat and the rotating shaft are connected. A pair of meshing gears are installed inside the housing, and the rotating shaft at the bottom of the gears is connected to a gear on the corresponding coaxial axis. One side wall of the housing is connected to the input end of the vacuum pump via a negative pressure pipe, and the other side wall of the housing is connected to the side wall of the first connecting seat via a tube that passes through the first partition. The axis of the opening of the negative pressure pipe and the tube corresponds to the meshing point of the gears.

[0014] In some embodiments, the sidewall of the shaft is provided with a plurality of second through holes spaced apart circumferentially, which can connect to the first connecting seat.

[0015] In some embodiments, the separation assembly includes a bracket, a second connecting seat, an output pipe, and a connecting pipe. The bottom of the shaft is connected to the second connecting seat, and the interior of the second connecting seat is connected to the cavity of the shaft. Multiple output pipes are spaced apart on the periphery of the second connecting seat, and a connecting pipe is rotatably connected to the bottom of the second connecting seat. The water-gas separator is equipped with a bracket located below the second partition, and the connecting pipe passes through the bracket. The end of the connecting pipe extends through the side wall of the water-gas separator to the outside.

[0016] In some embodiments, the base is provided with a cabinet, and the vacuum pump and the air compressor are provided inside the cabinet.

[0017] The beneficial effects of this invention are: 1. The airflow generated by the vacuum pump serves as the power source, driving the shaft to rotate via a pneumatic assembly. On one hand, the shaft, in conjunction with the separation assembly, synchronously generates centrifugal force, causing denser water droplets in the water-air mixture to be thrown against the inner wall of the water-air separator, where the discharged water is stored in the chamber below the second partition. On the other hand, the cavity inside the shaft serves as a gas channel, through which the gas obtained from water separation enters the pneumatic assembly and vacuum pump, forming a reflux. This active centrifugal separation improves water-air separation efficiency, achieving dynamic and enhanced separation of the water-air mixture before it enters the vacuum pump, effectively preventing liquid water from entering. Finally, the drainage assembly uses high-pressure gas to drain the water accumulated inside the chamber, achieving the drainage function. Attached Figure Description

[0028] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0029] Combination Figures 1 to 6 As shown, this embodiment is a zoned drainage control device for coastal reclamation soil, including a base 1, a water-air separator 3, a pneumatic assembly, a separation assembly, and a drainage assembly. The base 1 has the water-air separator 3, a vacuum pump providing vacuum adsorption power, and an air compressor providing high-pressure gas on its top. The water-air separator 3 has a first partition 9 and a second partition 10 inside, which divide the interior of the water-air separator 3 from top to bottom into a first chamber above the first partition 9, a second chamber between the first partition 9 and the second partition 10, and a third chamber below the second partition 10. A shaft 15 is rotatably mounted between the first partition 9 and the second partition 10, and a cavity 27 is located inside the shaft 15.

[0030] A pneumatic assembly is located at the top of the first partition 9. Both ends of the pneumatic assembly are connected to the input end of a vacuum pump and the top of the cavity 27 of the shaft 15, respectively. The pneumatic assembly is connected to the shaft 15. A separation assembly is located below the second partition 10. The interior of the separation assembly is connected to the bottom of the cavity 27 of the shaft 15. The input end of the separation assembly penetrates the side wall of the water-air separator 3 to introduce the water-air mixture discharged from the backfill. The pneumatic assembly can drive the shaft 15 to rotate around its own axis under the action of airflow, causing the shaft 15 to drive the separation assembly to rotate. Then, under centrifugal force, the water in the water-air mixture is discharged through the output end of the separation assembly into the third chamber.

[0031] A drainage component is provided below the separation component. The drainage component is connected to the output end of the air compressor. When the water level in the third chamber reaches the preset water level threshold, the drainage component can output high-pressure gas to discharge the water inside the chamber to the outside of the water-gas separator 3.

[0032] In some implementations, a cabinet 2 is mounted on the base 1. A vacuum pump (not shown) and an air compressor (not shown) are installed inside the cabinet 2. The input end of the vacuum pump is connected to a water-gas separator 3 via a pipe passing through the cabinet 2. The output end of the air compressor is connected to a drainage assembly via a pipe passing through the cabinet 2. The air compressor can supply high-pressure gas to the drainage assembly. Specifically, in this embodiment, both the vacuum pump and the air compressor are conventional devices.

[0033] By setting up cabinet 2, the vacuum pump can be protected from dust, water, and mechanical damage to a certain extent, which is especially suitable for the humid and salt spray corrosive environment of the coastal zone and extends the service life of the equipment.

[0034] In some implementation schemes, such as Figure 2 and Figure 3 As shown, the pneumatic assembly includes a housing 13, gears 21, a negative pressure pipe 8, and a tube 14. The housing 13 is mounted on the top of the first partition 9, and the bottom of the first partition 9 is connected to a first connecting seat 22 via multiple rods 30. A rotating shaft is rotatably connected inside the first connecting seat 22, and the first connecting seat 22 communicates with the cavity 27 of the rotating shaft. A pair of meshing gears 21 are installed inside the housing 13. The rotating shaft at the bottom of the gears 21 is connected to the corresponding coaxial gear 21. One side wall of the housing 13 is connected to the input end of the vacuum pump via the negative pressure pipe 8, and the other side wall of the housing 13 is connected to the side wall of the first connecting seat 22 via the tube 14 that passes through the first partition 9. The axes of the openings of the negative pressure pipe 8 and the tube 14 correspond to the meshing points of the gears 21.

[0035] The negative pressure airflow generated by the vacuum pump forms a high-speed airflow in the meshing area of ​​gear 21, driving gear 21 to rotate. By using a pair of meshing gears 21, the airflow energy can be converted into stable mechanical rotation, achieving the drive of shaft 15 without external power. After shaft 15 rotates, it can drive the separation component to rotate. At the same time, in this embodiment, lightweight gears can be used for gear 21 to reduce the torque required for starting, allowing the gears to accelerate faster and optimizing the response of the pneumatic component.

[0036] In some implementations, the device also includes connectivity components, such as Figure 4 As shown, the side wall of the shaft 15 is provided with a plurality of first through holes 28 spaced around it. An air inlet pipe 23 is connected to the first through hole 28 of the shaft 15. The second partition 10 is provided with a plurality of flow ports. A communication component is provided on the second partition 10. The communication component can obtain the pressure information of the third chamber and control the opening and closing of the flow ports based on the pressure information, so that the gas in the third chamber can flow into the second chamber.

[0037] Furthermore, the connecting components include a solenoid valve 11, a pressure sensor 12, and a controller. Both the pressure sensor 12 and the solenoid valve 11 are communicatively connected to the controller. The solenoid valve 11 is located at the flow port, and the pressure sensor 12 is installed through the second partition 10. The pressure sensor 12 can acquire the air pressure information inside the third chamber. If the air pressure information is higher than the preset air pressure threshold inside the controller, the solenoid valve 11 is controlled to block the flow port; if the air pressure information is lower than the preset air pressure threshold inside the controller, the solenoid valve 11 is controlled to open the flow port.

[0038] Furthermore, the sidewall of the shaft 15 is provided with a plurality of second through holes 29 at intervals around the circumference, which can connect to the first connecting seat 22.

[0039] Furthermore, the connecting component also includes a liquid level sensor (not shown in the figure). The liquid level sensor is communicatively connected to the controller. A liquid level sensor is installed in the chamber below the second partition. The liquid level sensor can acquire the liquid level information inside the chamber below the second partition. If the liquid level information is higher than the preset water level threshold inside the controller, the drainage component is controlled to release high-pressure gas into the chamber below the second partition to discharge the water outward. Specifically, in this embodiment, both the pressure sensor 12 and the liquid level sensor use conventional detection devices in the art.

[0040] By cooperating with the solenoid valve 11, the gas flow between the third chamber and the second chamber is actively controlled. When the pressure in the third chamber becomes too high due to a large air intake, the flow port is automatically closed to prevent unseparated water vapor from directly entering the second chamber, and to facilitate subsequent control of the drainage component to drain water from the third chamber.

[0041] In some implementation schemes, such as Figure 5 As shown, the separation assembly includes a bracket 26, a second connecting seat 24, an output pipe 25, and a connecting pipe 4. The bottom of the shaft 15 is connected to the second connecting seat 24, and the interior of the second connecting seat 24 is connected to the cavity 27 of the shaft 15. Multiple output pipes 25 are spaced apart on the periphery of the second connecting seat 24, and the interior of the second connecting seat 24 is connected to the output pipes 25. The bottom of the second connecting seat 24 is rotatably connected to the top of the connecting pipe 4. The bracket 26 located below the second partition 10 is installed inside the water-gas separator 3. The connecting pipe 4 is installed through the bracket 26. The end of the connecting pipe 4 away from the bracket 26 extends through the side wall of the water-gas separator 3 to the outside. The connecting pipe 4 is used to connect to external pipelines.

[0042] When gear 21 drives shaft 15 to rotate, shaft 15 drives second connecting seat 24 to rotate. The output pipes 25 around the second connecting seat 24 rotate synchronously at high speed. This causes the water-air mixture entering the second connecting seat 24 through connecting pipe 4 to be centrifugally separated. Water is thrown to the outer wall and flows down the pipe wall, while gas flows upward from the center, achieving efficient centrifugal separation. Multiple output pipes 25 drain water simultaneously, improving drainage efficiency and preventing localized water accumulation.

[0043] Regarding the synergistic effect of airflow distribution and centrifugal separation within the device, after the water-gas mixture enters the second connecting seat, a negative pressure is created inside due to the suction effect of the vacuum pump, causing the gas to naturally flow towards the low-pressure area. The output pipe generates centrifugal force under high-speed rotation, primarily separating the liquid water from the water-gas mixture, throwing the water towards the tank wall, while the gas, due to its lower density and inertia, more easily flows upward into the shaft cavity. These two paths are not completely independent but complementary.

[0044] The centrifugal separation path involves rotating the output tube to enhance water-gas separation efficiency, ensuring the gas entering the shaft cavity is relatively "dry" and reducing water droplet carryover. The drive path, as the main channel for gas flow, must ensure sufficient airflow to drive the pneumatic components. While a high output tube separation efficiency might reduce the amount of gas entering the shaft cavity, the vacuum pump's suction will maintain continuous airflow through the cavity. In reality, gas flow preferentially follows the path of least resistance, and the shaft cavity, due to its straight-through design, has low resistance; therefore, most gas likely still drives the gears via this path. Specifically, adjusting the orifice diameter or length of the output tube and shaft cavity can balance the airflow distribution between the two paths, ensuring sufficient airflow to drive the gears. Simultaneously, testing verifies the separation efficiency by measuring the gas flow rate and moisture content before and after output tube rotation to confirm whether centrifugal separation significantly reduces water droplet carryover without severely impacting the drive airflow.

[0045] In some implementation schemes, such as Figure 6 As shown, the drainage assembly includes a fixed plate 16, a first connecting pipe 18, a second connecting pipe 19, a high-pressure tank 17, a positive pressure pipe 7, and a valve 20. The valve 20 is communicatively connected to the controller. The inner wall of the water-air separator 3 is provided with multiple fixed plates 16 located below the first partition 9 along the circumferential direction. The high-pressure tank 17 is installed on the fixed plate 16. The outer walls of the multiple high-pressure tanks 17 are connected to the first connecting pipe 18 and the second connecting pipe 19 arranged in a double ring. Both the first connecting pipe 18 and the second connecting pipe 19 are connected to the high-pressure tank 17. The first connecting pipe 18 is connected to the output end of the air compressor via the positive pressure pipe 7. The valve 20 is provided on the first connecting pipe 18 or the second connecting pipe 19. The figure only shows the valve 20 installed on the second connecting pipe 19.

[0046] High-pressure gas supplied by an air compressor is filled into the high-pressure tank 17 for storage.

[0047] In some implementation schemes, such as Figure 1 As shown, the bottom of the water-gas separator 3 is equipped with a drain pipe 5, and a pressure relief valve 6 is installed on the drain pipe 5.

[0048] When the water level inside the third chamber rises, the controller obtains the water level information detected by the level sensor. If the water level is higher than the preset water level threshold inside the controller, the valve 20 on the second connecting pipe 19 is opened, allowing gas from the high-pressure tank 17 to enter the third chamber, causing the air pressure inside the third chamber to rise rapidly. The controller obtains the air pressure information detected by the air pressure sensor 12 inside the third chamber. If the pressure information is higher than the preset air pressure threshold inside the controller, the controller controls the solenoid valve 11 to close, preventing gas from flowing from the third chamber into the second chamber through the flow port. The high-pressure gas inside the high-pressure tank 17 continues to flow into the third chamber through the second connecting pipe 19 and the valve 20, causing the air pressure inside the third chamber to rise further until the air pressure reaches the preset air pressure threshold of the pressure relief valve 6 on the drain pipe 5. The pressure relief valve 6 then opens, and the water in the third chamber is discharged through the drain pipe 5 and the pressure relief valve 6. If the pressure information is lower than the preset air pressure threshold inside the controller, the controller controls the solenoid valve 11 to open and the valve 20 to close. If the preset air pressure threshold is not reached, the pressure relief valve 6 will close accordingly, so that the gas separated from the water in the third chamber can enter the second chamber through the flow port.

[0049] The implementation principle of the coastal reclaimed soil zone drainage control device in this embodiment is as follows: The operation of the vacuum pump drives the pneumatic components, which in turn rotates the shaft 15. The rotation of the shaft 15 then drives the second connecting seat 24 and the output pipe 25 to rotate. This linkage design allows the water-air mixture output through the output pipe 25 to have a high velocity, achieving efficient water-air separation under the action of centrifugal force.

[0050] The cavity 27 within the shaft 15 is connected to multiple air inlet pipes 23. As the shaft 15 rotates, the air inlet pipes 23 also rotate, forming a dynamic air inlet. This dynamic design makes it difficult for water droplets to adhere stably in high-speed airflow and pass through the air inlet pipes 23 into the cavity 27, effectively preventing water droplets from entering the vacuum pump. Furthermore, the cavity 27 provides a stable channel for gas transmission.

[0051] Automatic drainage control is achieved by incorporating components such as a high-pressure tank 17, a first connecting pipe 18, a second connecting pipe 19, a valve 20, and a pressure sensor 12 within the water-gas separator 3. During operation, the air compressor continuously injects gas into the first connecting pipe 18 via the positive pressure pipe 7, which then enters each high-pressure tank 17 for storage. When the water level in the water-gas separator 3 is high, the valve 20 is switched on, allowing the stored gas in the high-pressure tank 17 to be output through the valve. Upon receiving the pressure information from the pressure sensor 12, the controller closes the solenoid valve 11 of the second partition 10, causing the pressure below the water-gas separator 3 to rise rapidly until the pressure in the third chamber reaches the preset pressure threshold of the pressure relief valve 6. The pressure relief valve 6 then opens, allowing water to be discharged through the drain pipe 5 and the pressure relief valve 6. This automatic control system improves the intelligence level of the equipment, reduces the need for manual intervention, and also increases drainage efficiency.

[0052] Example 2: This embodiment describes a method for using a zoned drainage control device for coastal reclaimed land, including the following steps: First, insert the drainage hoses into the backfill soil, then connect each drainage hose through the pipeline, then connect the pipeline to the connecting pipe 4, and turn on the vacuum pump. When the vacuum pump is working, a negative pressure difference is formed between the drainage belt inside the backfill soil and the water-gas separator 3, which causes the water-gas mixture in the soil to enter the connecting pipe 4 through the drainage belt, and then enter the second connecting seat 24 through the connecting pipe 4. The water in the water-gas mixture is output to the bottom of the third chamber through the output pipe 25 on the second connecting seat 24. The gas separated in the third chamber then passes through the solenoid valve 11 on the second partition 10, enters the second chamber, and then enters the cavity 27 of the shaft 15 through the air inlet pipe 23. Then it enters the first connecting seat 22 through the second through hole 29, then enters the housing 13 through the pipe 14, and finally enters the vacuum pump through the negative pressure pipe 8. As the gas flows through the housing 13, a pair of meshing gears 21 are driven to rotate by the high-speed airflow. During the rotation of the gears 21, the second connecting seat 24 and the output pipe 25 are driven to rotate through the shaft 15, so that the water-gas mixture output through the output pipe 25 has a high speed. Under the action of centrifugal force, the water in the water-gas mixture is thrown towards the inner wall of the water-gas separator 3 and flows down along the inner wall of the tank to promote water-gas separation. The gas enters the chamber between the first partition 9 and the second partition 10 through the solenoid valve 11 on the second partition 10. The rotation of the shaft 15 causes the air inlet pipe 23 to rotate as well, thereby reducing the risk of large water droplets entering the chamber 27 through the air inlet pipe 23, and reducing the possibility of water entering the vacuum pump. During operation, the vacuum pump continuously injects gas into the first connecting pipe 18 through the positive pressure pipe 7, and then into each high-pressure tank 17 for storage. When the water-gas separator 3 has a large amount of water, the valve 20 is turned on. After the valve 20 is working, the high-pressure gas stored in the high-pressure tank 17 is output through the second connecting pipe 19 and the valve 20. At this time, the pressure sensor 12 detects the pressure information. Subsequently, the controller controls the solenoid valve to close the flow port on each second partition 10 based on the pressure information, so that the pressure below the second partition 10 rises rapidly, and the water in the water-gas separator 3 below the second partition 10 is discharged from the water-gas separator 3 through the drain pipe 5 and the pressure relief valve 6.

[0053] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
