Description

Technical Field

[0001] This utility model belongs to the technical field of precipitation equipment, and in particular relates to a vacuum dewatering device. Background Technology

[0002] Soft soil is widely distributed in my country, mainly located in coastal areas, plains, inland lake basins, depressions, and along riverbanks. To improve land use efficiency, it is often necessary to quickly construct large-scale storage yards, parking lots, and other facilities on these soft soil foundations. However, because soft soil foundations are rich in moisture, their strength and stability are usually low, thus requiring foundation treatment to enhance their bearing capacity.

[0003] In the process of treating soft soil foundations, a common method is to install dewatering wells. The main function of dewatering wells is to allow water in the foundation to flow into the well through natural infiltration, and then pump it out to reduce the moisture content of the foundation. Although this method can reduce the moisture content of the foundation to a certain extent, the dewatering efficiency is low due to the slow natural infiltration rate, which in turn affects the overall construction progress. Utility Model Content

[0004] To address the technical problems of low dewatering efficiency and impact on construction progress caused by existing dewatering wells, this utility model provides a vacuum dewatering device.

[0005] This utility model is implemented as follows: a vacuum dewatering device includes: a pressure plate, on which a vertical pipe for dewatering soft soil foundations is provided, and the vertical pipe has seepage holes; a cover is provided on the vertical pipe, on which a housing is fixedly installed, on which a discharge pipe is fixedly installed, on which a flexible hose is fixedly installed, and at one end of the flexible hose a water-air dual-purpose pump is fixedly installed; and a pulling mechanism for raising and lowering the water-air dual-purpose pump is assembled on the housing.

[0006] Preferably, the pulling mechanism includes: a rotating shaft rotatably mounted on the housing, a cylindrical body fixedly sleeved on the rotating shaft, and a pull rope fixedly mounted on the cylindrical body; a fixing ring fixedly mounted on the pull rope, the fixing ring being fixedly connected to the water-air dual-purpose pump; a servo motor fixedly mounted on one side of the housing, a first bevel gear fixedly mounted on the output shaft of the servo motor; and a second bevel gear fixedly mounted on the rotating shaft, the second bevel gear meshing with the first bevel gear.

[0007] Preferably, a bracket is fixedly installed on the inner wall of the housing, and a guide wheel for limiting the position of the pull rope is rotatably installed on the bracket.

[0008] Preferably, a sealing ring is fixedly sleeved on the cover, and the sealing ring is in contact with the inner wall of the vertical pipe.

[0009] Preferably, a cover for protecting the servo motor is provided on one side of the housing, and the cover is fixedly installed on the housing by bolts.

[0010] Preferably, an inspection port is provided on one side of the housing, and a sealing door is provided on the inspection port.

[0011] Preferably, the discharge end of the water-air dual-purpose pump is fixedly connected to the bottom end of the hose, and a filter screen is provided on the suction end of the water-air dual-purpose pump.

[0012] Preferably, the cover has an opening located outside the hose and the pull cord.

[0013] Compared with related technologies, the vacuum drainage device provided by this utility model has the following beneficial effects:

[0014] This solution utilizes a combination of a water-air dual-purpose pump, a hose, and a discharge pipe to expel gas from the riser, creating a vacuum within it. Under this negative pressure, water from the cracks in the soft soil foundation is quickly drawn into the riser. Since the water-air dual-purpose pump can pump both air and water, the water drawn into the riser can also be discharged simultaneously, significantly improving dewatering efficiency and accelerating construction progress. The pump can be raised and lowered using a pulling mechanism. In case of pump failure, it can be lifted into the housing. Once inside, maintenance can be easily performed by simply opening the sealing door. Attached Figure Description

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification and the foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification or the foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a vacuum drainage device, such as... Figure 1-4 As shown, the vacuum dewatering device includes: a pressure plate 1, on which a vertical pipe 2 for dewatering soft soil foundations is provided, and a seepage hole 3 is provided on the vertical pipe 2; a cover 4 is provided on the vertical pipe 2, on which a housing 5 is fixedly installed, on which a discharge pipe 6 is fixedly installed, on which a flexible hose 7 is fixedly installed, and at one end of the flexible hose 7 a water-air dual-purpose pump 8 is fixedly installed; and a pulling mechanism for raising and lowering the water-air dual-purpose pump 8 is assembled on the housing 5.

[0023] In this scheme, when using this device to dewater soft soil foundations, suitable holes are first drilled in the foundation using a compaction device. Then, a crane or other related equipment is used to install the device into the drilled holes. After installation, moisture in the foundation flows from the seepage hole 3 into the vertical pipe 2. To allow water to enter the vertical pipe 2 more quickly, a water-air pump 8 can be activated to remove the gas from the vertical pipe 2. The removed gas is discharged through the hose 7 and the discharge pipe 6, creating a vacuum inside the vertical pipe 2. Under the negative pressure of this vacuum, water in the foundation cracks is quickly drawn into the vertical pipe 2. The water-air dual-purpose pump 8, as the name suggests, is a miniature water pump that can pump both water and air. When water in the foundation is drawn into the vertical pipe 2, the water-air dual-purpose pump 8 can simultaneously discharge the water that has entered the vertical pipe 2 through the hose 7 and the discharge pipe 6. This greatly improves the efficiency of rainwater removal and has a good working effect. When the water-air dual-purpose pump 8 malfunctions and needs to be repaired, the pulling mechanism can be activated to raise the water-air dual-purpose pump 8 into the housing 5. After the water-air dual-purpose pump 8 enters the housing 5, the sealing door 21 can be opened to carry out the repair work, which is quite convenient.

[0024] In a further preferred embodiment of this utility model, the pulling mechanism includes: a rotating shaft 9 rotatably mounted on the housing 5, a cylindrical body 10 fixedly sleeved on the rotating shaft 9, and a pull rope 11 fixedly mounted on the cylindrical body 10; a fixing ring 12 fixedly mounted on the pull rope 11, the fixing ring 12 being fixedly connected to the water-air dual-purpose pump 8; a servo motor 13 fixedly mounted on one side of the housing 5, a first bevel gear 14 fixedly mounted on the output shaft of the servo motor 13; and a second bevel gear 15 fixedly mounted on the rotating shaft 9, the second bevel gear 15 meshing with the first bevel gear 14.

[0025] In this embodiment, the pulling mechanism is used to raise and lower the water-air dual-purpose pump 8. When in use, the servo motor 13 is started, which drives the first bevel gear 14 to rotate. The first bevel gear 14 drives the second bevel gear 15 to rotate, and the second bevel gear 15 drives the rotating shaft 9 to rotate on the housing 5. The rotating shaft 9 drives the cylinder 10 to rotate, so that the cylinder 10 can wind up or unwind the pull rope 11. When winding up, the water-air dual-purpose pump 8 can be raised into the housing 5. When unwinding, the water-air dual-purpose pump 8 can be lowered to the bottom of the vertical pipe 2 for use.

[0026] In a further preferred embodiment of the present invention, a bracket 16 is fixedly installed on the inner wall of the housing 5, and a guide wheel 17 for limiting the position of the pull rope 11 is rotatably installed on the bracket 16.

[0027] In this embodiment, the use of guide wheel 17 can effectively prevent the pull rope 11 from swaying left and right when the water-air dual-purpose pump 8 is raised and lowered using the pull rope 11, so that the water-air dual-purpose pump 8 can be relatively stable during the raising and lowering process.

[0028] In a further preferred embodiment of the present invention, a sealing ring 18 is fixedly sleeved on the cover 4, and the sealing ring 18 is in contact with the inner wall of the vertical tube 2.

[0029] In this embodiment, the use of the sealing ring 18 can significantly enhance the sealing performance between the cover 4 and the vertical tube 2, ensuring the sealing performance of the vertical tube 2.

[0030] In a further preferred embodiment of the present invention, a cover 19 for protecting the servo motor 13 is provided on one side of the housing 5, and the cover 19 is fixedly installed on the housing 5 by bolts 20.

[0031] In this embodiment, the use of the cover 19 can prevent the servo motor 13 from being interfered with or damaged by the external environment.

[0032] In a further preferred embodiment of the present invention, an inspection port is provided on one side of the housing 5, and a sealing door 21 is provided on the inspection port.

[0033] In this embodiment, the design of the inspection port and the sealing door 21 allows maintenance personnel to easily inspect the equipment inside the housing 5. When performing maintenance work, they only need to open the sealing door 21 from the inspection port.

[0034] In a further preferred embodiment of the present invention, the discharge end of the water-air dual-purpose pump 8 is fixedly connected to the bottom end of the hose 7, and a filter screen is provided on the suction end of the water-air dual-purpose pump 8.

[0035] In this embodiment, by using a filter screen, impurities that enter the water-air dual-purpose pump 8 can be filtered out, preventing impurities from damaging the water-air dual-purpose pump 8.

[0036] In a further preferred embodiment of the present invention, the cover 4 has an opening located outside the hose 7 and the pull rope 11.

[0037] In this embodiment, the opening allows the hose 7 and the pull rope 11 to move freely within the housing 5 and the vertical tube 2.

[0038] In summary, compared with related technologies, this solution, through the combined use of the water-air dual-purpose pump 8, hose 7, and discharge pipe 6, can expel the gas inside the vertical pipe 2, creating a vacuum inside the vertical pipe 2. Under the negative pressure of the vacuum, water in the cracks of the soft soil foundation will be quickly drawn into the vertical pipe 2. Since the water-air dual-purpose pump 8 can both pump air and water, the water drawn into the vertical pipe 2 can also be discharged at the same time, which can greatly improve the dewatering efficiency and help improve the construction progress. The water-air dual-purpose pump 8 can be raised and lowered by the pulling mechanism. When the water-air dual-purpose pump 8 malfunctions, it can be raised into the housing 5. Once the water-air dual-purpose pump 8 is inside the housing 5, it can be inspected and repaired by simply opening the sealing door 21, which is quite convenient.
