Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering drainage, and in particular to a water conservancy drainage device based on water conservancy engineering. Background Art

[0002] Drainage engineering is a type of water conservancy project, which refers to the collection and discharge of human sewage and various wastewater from production, excess surface water and groundwater (lowering the groundwater level). The main facilities include drainage ditches or pipelines at all levels and their ancillary buildings. During operation, water pumps or other water-lifting machinery, sewage treatment buildings, etc. can be added depending on the different drainage objects and drainage requirements. It is mainly used in farmland, mines, towns and construction sites.

[0003] Chinese patent number CN111893967B discloses a soil drainage device, comprising a housing, a filter unit, an air pressurizing unit and a piping unit. The housing comprises a bottom wall, a peripheral wall, a top cover, and two partitions arranged in the peripheral wall to define a main engine room, a water collecting chamber and a water storage chamber. The top cover is provided with a top perforation and is connected to the water collecting chamber through a connecting pipe. The water collecting chamber and the water storage chamber are connected through the perforations of the partition. The peripheral wall is provided with a plurality of slots for connecting the water collecting chamber with the outside world. The filter unit comprises a filter screen arranged on the outside of the top cover to cover the top perforation, and a filter screen arranged in the water collecting chamber and covering the slots. The air pressurizing unit comprises a control module and an air pump arranged in the main engine room. The piping unit comprises an air inlet pipe for connecting the main engine room with the outside world, a drain pipe for connecting the water storage chamber with the outside world, and a drainage air guide pipe for introducing the gas output by the air pump into the water storage chamber. Soil drainage devices can be buried in the soil to collect ground water and water in the soil using the principles of gravity and infiltration, and then use air pressure to drain the water, which can improve drainage efficiency.

It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0032] First embodiment:

[0033] A hydraulic drainage device based on a hydraulic engineering project, such as Figure 1-Figure 5 As shown, it includes an outer cylinder 1, a drawing pipe 2 and a first filter plate 5 arranged on the side wall of the outer cylinder 1, and a drawing port 36 is provided at the bottom end of the outer surface of the drawing pipe 2; a drill bit 3 is rotatably connected to the bottom of the outer cylinder 1, and a mounting frame 4 is fixedly connected to the top of the outer cylinder 1, and a pressing handle 6 is slidably fitted on the mounting frame 4, and the drawing pipe 2 is coaxially rotatably connected to the pressing handle 6; the pressing handle 6 includes a positioning ring, which is coaxially rotatably connected to the drawing pipe 2, and a handle is fixedly connected to the positioning ring, and a guide groove 15 is provided on the mounting frame 4, and the outer surface of the handle is slidably fitted with the inner wall of the guide groove 15; when the pressing handle 6 moves up and down along the guide groove 15, it drives the drawing pipe 2 to move up and down; a protective net 47 is provided on the top of the outer cylinder 1 to prevent foreign objects from entering the outer cylinder 1 from above.

[0034] The bottom end of the drawing tube 2 is coaxially inserted into the outer cylinder 1, and the bottom end of the drawing tube 2 is coaxially fixedly connected with a chimera, a one-way rotating mechanism is coaxially provided on the drill bit 3, and the chimera is drivingly connected to the embedded end of the one-way rotating mechanism; a rotating driving mechanism is provided on the mounting frame 4, and the rotating driving mechanism is drivingly connected to the top end of the drawing tube 2, and a first spring 7 is installed between the top of the outer cylinder 1 and the bottom of the pressing handle 6. When the chimera is in a chimeric state with the one-way rotating mechanism, the rotating driving mechanism drives the drawing tube 2 to rotate, which can drive the drill bit 3 to rotate.

[0035] A middle cylinder 8 is fixedly connected inside the outer cylinder 1, and an inner cylinder 9 is fixedly connected inside the middle cylinder 8. An opening is provided at the bottom of the middle cylinder 8, and the height position of the bottom of the middle cylinder 8 is lower than the height position of the bottom of the inner cylinder 9. There is a distance between the bottom of the middle cylinder 8 and the top of the drill bit 3, and the specific distance length should be set according to demand; a second filter plate 10 is provided on the side wall of the inner cylinder 9, and a floating block 11 is slidably connected inside the inner cylinder 9. The middle cylinder 8, the inner cylinder 9 and the floating block 11 are all slidably connected with the extraction pipe 2; a connecting rod 12 is slidably connected to the top wall of the outer cylinder 1, and a detection plate 13 is fixedly connected to the top of the connecting rod 12. A distance sensor 14 is installed at the bottom of the pressure handle 6, and the detection part of the distance sensor 14 is arranged toward the detection plate 13. The rotary drive mechanism is electrically connected to the distance sensor 14, and the bottom end of the connecting rod 12 penetrates into the inner cylinder 9 and is fixedly connected to the top of the floating block 11.

[0036] In the initial state, the chimera and the one-way rotating mechanism are disengaged. When the pressure handle 6 is pressed down to lower the drawing tube 2, the chimera and the one-way rotating mechanism are engaged. It should be noted that the lowering of the pressure handle 6 will bring the distance sensor 14 down. When the chimera and the one-way rotating mechanism are engaged, the distance sensor 14 detects that the distance between the distance and the detection plate 13 is reduced to the set value, and the rotating drive mechanism drives the drawing tube 2 to rotate with the drill bit 3.

[0037] like Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the rotary drive mechanism includes a mounting shell 16 fixedly connected to the mounting frame 4, a fixing cylinder 17 is fixedly connected to the top of the mounting shell 16, an inner tube 18 is rotatably connected to the mounting shell 16, and the top of the inner tube 18 extends to the inside of the fixing cylinder 17, the bottom end of the inner tube 18 is inserted into the feed pipe 2, and a piston ring 24 is fixedly connected to the bottom end of the inner tube 18, and the edge of the piston ring 24 is in sliding sealing cooperation with the inner wall of the feed pipe 2, and the piston ring 24 can only slide in the feed pipe 2 and cannot rotate in the feed pipe 2. For example, the shapes of the inner wall of the feed pipe 2 and the outer surface of the piston ring 24 are both set to be elliptical.

[0038] A sleeve 19 is fixedly connected to one side of the mounting shell 16, and a center shaft 20 is coaxially passed through the sleeve 19 and rotatably connected. One end of the center shaft 20 that penetrates the mounting shell 16 is coaxially fixedly connected to a first bevel gear 21, and a second bevel gear 22 is coaxially fixedly connected to the inner tube 18 in the mounting shell 16, and the first bevel gear 21 is meshingly connected with the second bevel gear 22; a motor 23 is installed on the mounting frame 4, and the motor 23 is a servo motor that can rotate forward and backward, and the speed of the motor 23 can be adjusted according to demand; the output end of the motor 23 is coaxially fixedly connected to the other end of the center shaft 20, and the distance sensor 14 is electrically connected to the motor 23; when the motor 23 drives the center shaft 20 to rotate, the first bevel gear 21 rotates synchronously with the center shaft 20, driving the second bevel gear 22 to rotate with the inner tube 18, and the piston ring 24 to rotate with the extraction pipe 2.

[0039] A first one-way bearing 25 is coaxially connected to the central axis 20 in the sleeve 19. In the present embodiment, the first one-way bearing 25 will rotate only when the central axis 20 rotates in the opposite direction. The first one-way bearing 25 is provided with a fan blade 26. The sleeve 19 is provided with an input port 27 and an output port 28. The output port 28 is connected to an external discharge pipe, and the input port 27 is fluidically connected to the fixed cylinder 17 through a pipe.

[0040] like Figure 2 and Figure 6As shown, the chimera includes a rotating block 29 coaxially fixed to the bottom end of the extraction tube 2, a fitting groove 30 is provided at the bottom of the rotating block 29, a top block 31 is fixedly connected to the inner wall of the fitting groove 30, and a one-way paddle 32 is fixedly connected to the outer surface of the rotating block 29; a conical groove 40 is provided at the top of the drill bit 3, a swivel is rotatably connected to the conical groove 40, a scraper 41 is provided on the swivel, one side of the scraper 41 is in contact with the inner wall of the conical groove 40, and the one-way paddle 32 matches the scraper 41; the one-way paddle 32 is inclined, when the rotating block 29 rotates forward, the one-way paddle 32 will be deformed when it contacts the scraper 41, and the scraper 41 will not rotate at this time, and only when the rotating block 29 rotates reversely, the one-way paddle 32 will paddle the scraper 41 to make the scraper 41 rotate around the swivel as the axis.

[0041] The one-way rotation mechanism includes a second one-way bearing 42 coaxially arranged on the inner bottom wall of the tapered groove 40. In the present embodiment, only when the second one-way bearing 42 rotates in the forward direction, the second one-way bearing 42 rotates with the drill bit 3; the top of the second one-way bearing 42 is fixedly connected with an engaging block 43. When the engaging block 43 is embedded in the engaging groove 30, the rotating block 29 rotates to drive the top block 31 to abut against the engaging block 43 and rotate the second one-way bearing 42; when the second one-way bearing 42 rotates in the forward direction, the drill bit 3 rotates to perform drilling.

[0042] When the device in this embodiment is in use, first, the drill bit 3 is placed against the surface of the water-logged area, and the pressure handle 6 is pressed down to lower the feed pipe 2 (at the same time, the first spring 7 is compressed to store force), and the rotating block 29 follows the feed pipe 2 to descend and enables the engaging block 43 to be embedded in the engaging groove 30; it should be noted that the descending of the pressure handle 6 will bring the distance sensor 14 down with it, and when the engaging block 43 is embedded in the engaging groove 30, the distance sensor 14 detects that the distance between it and the detection plate 13 is reduced to a set value, and the control motor 23 is started, and the motor 23 drives the central shaft 20 The first bevel gear 21 drives the second bevel gear 22 to rotate forward with the inner tube 18, the piston ring 24 drives the extraction tube 2 to rotate forward, the rotating block 29 rotates to drive the top block 31 to abut the engaging block 43 to make the second one-way bearing 42 rotate forward, the drill bit 3 rotates and drills holes on the surface of the waterlogged area (the drilling depth is set according to demand). It should be noted that when the drilling work is completed, since the device is located in the hole, the device is installed, so the device has the characteristic of easy installation.

[0043] It is worth mentioning that during the use of the device, when it is necessary to interrupt the drilling work, it is only necessary to loosen the pressure handle 6, and the first spring 7 releases its force to expand. The first spring 7 pushes against the pressure handle 6 to rise, and the distance sensor 14 rises to increase the distance between it and the detection plate 13, the motor 23 is turned off, and the drill bit 3 stops rotating, thereby realizing the shutdown of the drilling work and improving the convenience of using the device; it should be noted that when the device is not in the drilling state (for example, when the staff carries the device by hand), through the setting of the first spring 7, the distance sensor 14 and the detection plate 13 are always in a state of being separated, that is, the drill bit 3 is always in a state of stopping rotation, thereby avoiding the drill bit 3 from rotating due to unexpected factors, thereby causing the occurrence of dangerous situations, thereby improving the safety of using the device.

[0044] After the hole is drilled, the pressure handle 6 is released, the first spring 7 expands and pushes the pressure handle 6 up, the motor 23 is automatically turned off to stop the drill bit 3, and then the rotation direction of the motor 23 is adjusted; it should be noted that when the pressure handle 6 rises, it also brings the extraction tube 2 up, and finally the extraction port 36 is located in the inner tube 9.

[0045] The water in the soil enters the outer cylinder 1 after being filtered by the first filter plate 5 , and the water in the outer cylinder 1 flows downward, and then flows into the middle cylinder 8 from the bottom opening of the middle cylinder 8 , and enters the inner cylinder 9 after secondary filtration by the second filter plate 10 .

[0046] It should be noted that since the height of the bottom of the middle cylinder 8 is lower than the height of the bottom of the inner cylinder 9 (the specific height difference is set according to demand), under the influence of gravity, a large amount of impurities in the water (the water contains a large amount of metal molecules, soil particles, etc.) will settle and fall into the conical groove 40, thereby reducing the impurity content of the water flowing into the inner cylinder 9, thereby reducing the possibility of clogging of the second filter plate 10 affecting the filtration efficiency.

[0047] After the water flows into the inner tube 9, the buoyancy causes the float 11 to rise, the connecting rod 12 rises against the detection plate 13, and the distance between the detection plate 13 and the distance sensor 14 decreases. When the water in the inner tube 9 reaches the set amount, the float 11 rises until the distance between the detection plate 13 and the distance sensor 14 decreases to the set value, the motor 23 starts and drives the central shaft 20 to rotate in the opposite direction, the first one-way bearing 25 drives the fan blade 26 to rotate, and the water in the inner tube 9 passes through the extraction port 36, the extraction pipe 2, the inner tube 9 in sequence. Tube 18, fixed cylinder 17, input port 27, and then the water is pumped into sleeve 19, and finally discharged into the external discharge pipe from output port 28, so as to realize the drainage function of the device (the motor 23 in the drainage process of the device can also be set to delay closing to prevent the inner cylinder 9 from having a small amount of water inflow, causing the water level in the inner cylinder 9 to drop rapidly due to the drainage work, causing the floating block 11 to drop and causing the detection plate 13 to quickly move away from the distance sensor 14, and the motor 23 to be turned off, resulting in the motor 23 being started and closed at a high frequency in a short time, thereby reducing the service life of the motor 23).

[0048] It should be noted that after the impurities fall into the conical groove 40, they slide along the inner wall of the conical groove 40 and converge toward the center. After the device has been used for a period of time, when the impurities in the conical groove 40 accumulate to a certain amount and need to be cleaned, the pressure handle 6 is pressed down to make the extraction tube 2 with the rotating block 29 descend again, and the distance sensor 14 detects that the distance between the detection plate 13 has dropped to the set value, and the motor 23 drives the central axis 20 to rotate in the opposite direction. According to the above-mentioned discharge principle, the impurities in the conical groove 40 are sucked into the external discharge pipe to realize the discharge of impurities.

[0049] It is worth mentioning that after the rotating block 29 descends, the engaging block 43 is embedded in the engaging groove 30. When the motor 23 drives the central shaft 20 to rotate in the reverse direction, the extraction tube 2 is driven to rotate in the reverse direction with the rotating block 29 (at this time, the second one-way bearing 42 is in the reverse rotation state, so the drill bit 3 will not rotate). The one-way paddle 32 drives the scraper bar 41 to rotate, and the scraper bar 41 scrapes off the impurities adhering to the inner wall of the conical groove 40. The scraped impurities gather toward the center of the bottom of the conical groove 40, so that the impurities in the conical groove 40 are extracted by the scraper bar 41 while the impurities on the inner wall of the conical groove 40 are scraped off, thereby improving the impurity removal effect.

[0050] Second embodiment:

[0051] Based on the first embodiment, Figure 3 and Figure 6 As shown, the upper sleeve 34, the lower sleeve 35 and the connecting ring 46 are provided on the drawing tube 2, and the upper sleeve 34, the lower sleeve 35 and the connecting ring 46 can slide along the drawing tube 2. In the initial state, the upper sleeve 34 and the lower sleeve 35 have a part to block the drawing port 36, and an elastic block 37 is fixedly connected between the upper sleeve 34 and the lower sleeve 35. The elastic block 37 can be stretched. When the upper sleeve 34 and the lower sleeve 35 are separated, the feeding area of ​​the drawing port 36 is increased; the top of the upper sleeve 34 is rotatably connected to the bottom of the connecting ring 46, and an elastic member 38 is fixedly connected between the bottom of the floating block 11 and the top of the connecting ring 46. The connecting ring 46 is a bearing. The friction between the ring 34 and the connecting ring 46 is relatively small; the elastic member 38 is an elastic rope, a spring or other existing suitable elastic member. It should be noted that when the elastic member 38 is an elastic rope, the elastic rope is always in a taut state during the operation of the device, but it is still extensible. When the elastic rope is in a taut state, it is ensured that the connecting ring 46 will not rotate with the upper ring 34, that is, it is ensured that the elastic rope will not be entangled during the operation of the device; a slide groove 33 is provided in the rotating block 29, and the bottom of the lower ring 35 extends into the slide groove 33 and can slide along the slide groove 33. A second spring 39 is installed between the inner top wall of the slide groove 33 and the inner bottom wall of the lower ring 35.

[0052] like Figure 5 and Figure 6As shown, a first magnetic block 44 is disposed on the inner bottom wall of the conical groove 40 , and a second magnetic block 45 is disposed at the bottom of the lower ring 35 . The first magnetic block 44 and the second magnetic block 45 are magnetically repelled.

[0053] When the device in this embodiment is in use, based on the drainage process of the first embodiment, when the water intake of the device is large, the floating block 11 continues to move upward while the drainage work is in progress, and the floating block 11 rises and pulls the elastic member 38, resulting in an increase in the tension applied by the elastic member 38 to the connecting ring 46. When the tension increases to a level higher than the resistance to the rise of the upper ring 34 (the resistance is the binding force of the elastic block 37 on the upper ring 34), the elastic block 37 stretches, so that the elastic member 38 pulls the connecting ring 46 and the upper ring 34 rises (in this embodiment, the elastic hardness of the second spring 39 is relatively high, and the second spring 39 will not be deformed at this time, that is, the position of the lower ring 35 remains unchanged), the upper ring 34 moves away from the lower ring 35, so that the feeding area of ​​the extraction port 36 is increased, thereby improving the drainage efficiency, and realizing the function of the device being able to autonomously adjust the drainage efficiency.

[0054] Based on the process of discharging impurities in the first embodiment, due to the low fluidity of the impurities, it is easy to cause the drawing port 36 to be blocked. During the operation of the device of this embodiment, when the drawing pipe 2 descends with the rotating block 29, the upper ring 34 and the lower ring 35 both descend, so that the tension applied by the elastic member 38 on the connecting ring 46 increases, and the connecting ring 46 brings the upper ring 34 away from the lower ring 35, and the upper ring 34 is far away from the lower ring 35, resulting in the upper ring 34 no longer blocking the drawing port 36. At this time, the feeding area of ​​the drawing port 36 is increased to the maximum, thereby reducing the possibility of clogging of the drawing port 36 during the discharge process.

[0055] It should be noted that, during the process of discharging impurities, the rotating block 29 is in a continuous rotating state. When the rotating block 29 rotates to the point where the first magnetic block 44 corresponds to the second magnetic block 45, the magnetic repulsion between the first magnetic block 44 and the second magnetic block 45 causes the second magnetic block 45 to push against the lower ring 35 and move slightly upward. At the same time, the second spring 39 is compressed to accumulate force, and then the rotating block 29 continues to rotate. When it rotates to the point where the first magnetic block 44 and the second magnetic block 45 no longer correspond, the second spring 39 releases its force and expands. The second spring 39 pushes against the inner bottom wall of the lower ring 35 to cause the lower ring 35 to descend and reset. That is, during the rotation of the rotating block 29, the lower ring 35 continuously vibrates up and down, causing the feeding area of ​​the extraction port 36 to continuously change slightly, thereby further preventing the extraction port 36 from being blocked during the discharge process.
