DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] A construction engineering drainage device, such as Figure 1 and Figure 2 and Figure 3 , including a drainage box 1 and a filter box 2 arranged on the top of the drainage box 1, a plurality of water troughs 3 connected to the drainage box 1 are opened at the bottom end of the filter box 2, a fan-shaped pad 4 is provided at the bottom end of the drainage box 1, and the pad 4 is located on one side of each water trough 3, a fan-shaped mounting plate 5 is provided at the top of the pad 4, and a plurality of filter components are evenly distributed along the curvature direction of the mounting plate 5 at the top of the mounting plate 5, each filter component includes a filter screen 6, a vertical pipe 7 is vertically fixedly connected to the bottom end of the filter box 2, and the vertical pipe 7 is connected to one of the filter components through a guide piece, a water pump 8 is provided on one side of the outer wall of the drainage box 1, and the water pump 8 is connected to the bottom end of the vertical pipe 7 through a water inlet pipe 9, and a drainage pipe 10 is provided on one side of the drainage box 1.

[0035] like Figure 1 and Figure 2 and Figure 3 When working, the construction wastewater is introduced into the vertical pipe 7 through the water inlet pipe 9 and the water pump 8, and then introduced into one of the filter components from the vertical pipe 7 through the guide piece, and the wastewater is filtered by the filter screen 6 in the filter component. The filtered water flows out of the filter component and flows into the bottom of the filter box 2, and then flows from each water trough 3 to the drainage box 1, and is discharged from the drainage pipe 10 on the drainage box 1;

[0036] When it is necessary to replace or clean the filter screen 6 in one of the filter components, it is only necessary to guide the wastewater into the next filter component through the guide member, and then remove the filter component that needs to be replaced or cleaned from the filter component for replacement or cleaning. At this time, the wastewater can continue to be filtered through the filter screen 6 in the next filter component without stopping the water inlet pipe 9, thereby improving the drainage efficiency of the drainage device.

[0037] like Figure 3 and Figure 4 A fixing ring 12 is provided at the top of the backing plate 4, the mounting plate 5 is located on the outside of the fixing ring 12, and the axis of the fixing ring 12 coincides with the axis of the mounting plate 5. There are six filter assemblies on the mounting plate 5, and the six filter assemblies also include seven baffles 13 arranged on the top of the mounting plate 5, and the seven baffles 13 are all located on the outside of the fixing ring 12 and are fixedly connected to the outer wall of the fixing ring 12, and the seven baffles 13 are distributed at intervals along the arc direction of the mounting plate 5. At this time, the seven baffles 13 divide the top of the mounting plate 5 into six filter areas 14, and the six filter screens 6 are respectively located at one end of the six filter areas 14 away from the fixing ring 12, and the filter screens 6 are installed on the baffles 13 on both sides of the filter area 14 through the mounting parts. A water inlet 15 connected to the filter area 14 is provided at one end of the inner wall of the fixed ring 12 close to the six filter areas 14. The guide member on the vertical pipe 7 is connected to one of the water inlets 15. The guide member includes a rotating pipe 16 rotatably connected to the top of the vertical pipe 7, and the top pipe opening of the rotating pipe 16 is connected to a horizontally arranged conduit 17. The end of the conduit 17 away from the rotating pipe 16 is connected to one of the water inlets 15 through a transition member. A gear ring 18 is coaxially provided on the outer wall of the rotating pipe 16. An L-shaped mounting frame 19 is provided at the bottom end of the fixed ring 12, and a first motor 20 is provided on the mounting frame 19. A gear 21 meshing with the gear ring 18 is provided at one end of the rotating shaft of the first motor 20. The first motor 20 is a servo motor.

[0038] like Figure 3 and Figure 4 The six filter areas 14 are respectively the first filter area 14, the second filter area 14, the third filter area 14, the fourth filter area 14, the fifth filter area 14, and the sixth filter area 14 from left to right along the arc direction of the mounting plate 5;

[0039] The six water inlets 15 are respectively the first water inlet 15, the second water inlet 15, the third water inlet 15, the fourth water inlet 15, the fifth water inlet 15, and the sixth water inlet 15 from left to right along the arc direction of the mounting plate 5;

[0040] The waste water in the vertical pipe 7 enters the conduit 17 through the rotating pipe 16. When the transition piece on the conduit 17 is connected with the first water inlet 15, the waste water in the conduit 17 flows into the first filter area 14 through the transition piece and the first water inlet 15, and then passes through the filter screen 6 in the first filter area 14 to filter the waste water. When the filter screen 6 in the first filter area 14 needs to be replaced or cleaned, it is only necessary to turn on the first motor 20. The rotating shaft of the first motor 20 drives the gear 21 to rotate. At this time, the gear 21 will pass through the filter screen 6 in the first filter area 14. The meshing gear ring 18 drives the rotating tube 16 to rotate, and the rotating tube 16 drives the conduit 17 and the transition piece to rotate along the rotating axis of the rotating tube 16 until the flow guide piece rotates to the second water inlet 15. At this time, the flow guide piece is connected with the second water inlet 15, and the wastewater flows into the second filter area 14. At this time, the wastewater can continue to be filtered through the filter screen 6 in the second filter area 14, and then the filter screen 6 in the first filter area 14 can be removed from the filter area 14 through the mounting piece for replacement or cleaning;

[0041] When it is necessary to replace or clean the filter screen 6 in the second filter area 14, the first motor 20 works until the guide member is rotated to be connected to the third water inlet 15, and the wastewater will flow into the third filter area 14. At this time, the wastewater can continue to be filtered through the filter screen 6 in the third filter area 14, and then the filter screen 6 in the second filter area 14 is removed from the filter area 14 through the mounting member for replacement or cleaning. Similarly, when the guide member is connected to the sixth water inlet 15, the wastewater in the vertical pipe 7 flows into the sixth filter area 14 through the guide member and the sixth water inlet 15. When it is necessary to replace or clean the filter screen 6 in the sixth filter area 14, the rotating shaft of the first motor 20 rotates in the opposite direction until the guide member is connected to the fifth water inlet 15. At this time, the wastewater can be filtered through the replaced or cleaned filter screen 6 in the fifth filter area 14, and then the filter screen 6 in the sixth filter area 14 is removed from the filter area 14 through the mounting member for replacement or cleaning.

[0042] Then, when it is necessary to replace or clean the filter screen 6 in the fifth filter area 14, the first motor 20 works to make the guide member continue to rotate in the opposite direction until the guide member is rotated to connect with the fourth water inlet 15. At this time, the waste water will flow into the fourth filter area 14. At this time, the waste water can be filtered by the replaced or cleaned filter screen 6 in the fourth filter area 14. Then, the filter screen 6 in the fifth filter area 14 can be removed from the filter area 14 through the mounting member for replacement or cleaning. Similarly, when the guide member rotates to the initial position connected with the first water inlet 15, the above process is repeated, and the filter screen 6 can be replaced or cleaned without stopping the water inlet pipe 9, thereby improving the drainage efficiency of the drainage device.

[0043] When the rotating tube 16 rotates clockwise, the guide member is connected with the first water inlet 15, the second water inlet 15, the third water inlet 15, the fourth water inlet 15, the fifth water inlet 15 and the sixth water inlet 15 in sequence. When the guide member is connected with the sixth water inlet 15 and the filter plate in the sixth filter area 14 needs to be replaced or cleaned, the rotating tube 16 rotates counterclockwise. At this time, the guide member is connected with the sixth water inlet 15, the fifth water inlet 15, the fourth water inlet 15, the fourth water inlet 15, the third water inlet 15, the second water inlet 15 and the first water inlet 15 in sequence, which is simple and convenient to use.

[0044] like Figure 4 The transition piece includes a swivel 22 coaxially rotatably connected to the fixed ring 12, and a guide port 23 connected to one of the water inlets 15 is opened on the outer wall of the swivel 22. The end of the conduit 17 away from the swivel tube 16 is located in the guide port 23 and fixedly connected to the inner wall of the guide port 23. The purpose of this arrangement is that when the swivel tube 16 drives the conduit 17 to rotate, the swivel 22 will rotate with the conduit 17. When the guide port 23 on the swivel 22 corresponds to the water inlet, the wastewater in the conduit 17 will flow to the water inlet 15 through the guide port 23 on the swivel 22, and then flow from the water inlet 15 into the filter area 14 connected to the water inlet 15. It is simple and convenient to use.

[0045] like Figure 6 The transition piece includes a slide cylinder 24 coaxially sleeved on the outer wall of the conduit 17, and the end of the slide cylinder 24 away from the rotating tube 16 is in conflict with the inner wall of the fixed ring 12. A ring body 25 is coaxially fixedly connected to the conduit 17. The ring body 25 is located between the slide cylinder 24 and the vertical tube 7, and a compression spring 26 is provided between the slide cylinder 24 and the ring body 25. The purpose of this arrangement is that when the rotating tube 16 drives the conduit 17 to rotate, the slide cylinder 24 will follow the conduit 17 to rotate. When the slide cylinder 24 corresponds to the water inlet, the waste water in the conduit 17 will flow to the water inlet 15 through the slide cylinder 24, and then flow from the water inlet 15 into the filter area 14 connected to the water inlet 15. The sleeve can always be in conflict with the inner wall of the transition ring through the compression spring 26, which is simple and convenient to use.

[0046] like Figure 3 and Figure 6 The top end of the conduit 17 is horizontally provided with a fan-shaped top plate 28 through an L-shaped connecting plate 27, and the top plate 28 is located above the baffle 13, and the bottom end of the top plate 28 is in contact with the baffle 13, the fixing ring 12, and the top of the filter screen 6. At this time, the top plate 28 closes one of the filter areas 14, and the opposite sides of the top plate 28 are respectively provided with a fan-shaped first side plate 29 and a second side plate 30, and the first side plate 29 and the second side plate 30 are used to close the two filter areas 14 adjacent to the filter area 14 below the top plate 28. At this time, the first side plate 29 and the second side plate 30 form a fan-shaped closing plate with the top plate 28.

[0047] like Figure 3 and Figure 6 , the wastewater entering the filter area 14 from below the closing plate can be reduced by the closing plate, and splashing out of the filter area 14 from above between the two baffles 13 in the filter area 14. When the rotating tube 16 and the conduit 17 rotate, the closing plate will follow the conduit 17 to rotate through the connecting plate 27. When the guide member is connected to the first water inlet 15, the top plate 28 will close the first filter area 14. At this time, the first side plate 29 will be located on the upper side of the mounting plate 5 and suspended in the air, and the second side plate 30 will close the second filter area 14. When the guide member is connected to the sixth water inlet 15, the top plate 28 will close the sixth filter area 14. At this time, the first side plate 29 will close the fifth filter area 14, and the second side plate 30 will be located on the upper side of the mounting plate 5 and suspended in the air;

[0048] When the conduit 17 rotates so that the guide member rotates to between two adjacent water inlets 15, the guide member will discharge the wastewater from the two water inlets 15 into two adjacent filter areas 14 respectively. At this time, when the guide member rotates to communicate with the next filter area 14, the first side plate 29 and the second side plate 30 on the top plate 28 can reduce the top plate 28 from following the rotation of the conduit 17. When the top plate 28 releases the closure of the filter area 14, the wastewater in the filter area 14 splashes out of the filter area 14.

[0049] When the filter screen 6 in the first filter area 14 needs to be replaced or cleaned, the guide piece is rotated to be connected to the second water inlet 15. At this time, the first side plate 29 closes the first filter area 14, and the second side plate 30 closes the third filter area 14. As time goes by, when the filter screen 6 in the second filter area 14 needs to be replaced or cleaned, the guide piece is rotated to be connected to the third water inlet 15. At this time, the first side plate 29 closes the second filter area 14, and the second side plate 30 closes the fourth filter area 14. At this time, the closure of the first filter area 14 will be released, and then the filter screen 6 in the first filter area 14 can be replaced or cleaned (such as Figure 3 ), as time goes by, when the filter screen 6 in the third filter area 14 needs to be replaced or cleaned, the guide piece is rotated to be connected with the fourth water inlet 15. At this time, the first side plate 29 closes the third filter area 14, and the second side plate 30 closes the fifth filter area 14. At this time, the closure of the second filter area 14 will be released, and then the filter screen 6 in the second filter area 14 can be replaced or cleaned. Similarly, it can reduce the splashing of waste water out of the filter area 14 while facilitating the replacement or cleaning of the filter screen 6 in the filter area 14, and at the same time facilitate the cleaning of impurities on the inner wall of the filter area 14. It is simple and convenient to use.

[0050] like Figure 3, the bottom ends of the six filter areas 14 are each provided with a mounting groove 32, and the mounting groove 32 is close to the filter screen 6, and six collecting boxes 33 are placed at the bottom end of the filter box 2, the six collecting boxes 33 correspond to the six mounting grooves 32 one by one, and the top of the collecting box 33 vertically extends into the mounting groove 32 and is flush with the top of the mounting plate 5, and the six collecting boxes 33 are all located on the outside of the pad 4. The purpose of this arrangement is that the impurities filtered out by the filter screen 6 in the filter area 14 can be collected through the collecting box 33. When cleaning or replacing the filter screen 6 in the filter area 14 and cleaning the impurities on the inner wall of the filter area 14, the impurities can be cleaned into the collecting box 33, and then the collecting box 33 can be taken out upwards, which is simple and convenient to use.

[0051] like Figure 3 and Figure 4 and Figure 7 The bottom end of the top plate 28 is rotatably connected to a rotating shaft 34, and the bottom end of the rotating shaft 34 is provided with an arc-shaped stirring rod 35, the stirring rod 35 is located in one of the filtering areas 14 and corresponds to the conduit 17, and the top of the top plate 28 is provided with a second motor 36 for driving the rotating shaft 34 to rotate through a fixed frame. When the closing plate rotates with the conduit 17 through the connecting plate 27, each baffle 13 is provided with a side groove 37 for the stirring rod 35 to pass through, and two vertical plates 38 are vertically downwardly provided at the bottom end of the top plate 28, and the two vertical plates 38 are respectively located on the two baffles 13 at the bottom end of the top plate 28. The side groove 37 of the mounting plate 5 is closed, and the leftmost and rightmost baffles 13 of the seven baffles 13 distributed along the arc direction of the mounting plate 5 are provided with a blocking block 39 corresponding to the side groove 37 on the side away from the filtering area 14. The purpose of this arrangement is that when the waste water is filtered through the filter screen 6 in the filtering area 14 and the rotating tube 16 stops rotating, the second motor 36 is turned on, and the rotating shaft of the second motor 36 drives the rotating shaft 34 to rotate. At this time, the stirring rod 35 on the rotating shaft 34 can stir the waste water in the filtering area 14, thereby facilitating the filtering of the filter screen 6;

[0052] When the rotating tube 16 and the conduit 17 rotate, and the closing plate rotates along with the conduit 17 through the connecting plate 27, the rotating shaft 34 is first driven to rotate by the rotating shaft of the second motor 36 until the arc-shaped stirring rod 35 is aligned with the side groove 37 on the baffle 13, and then the rotating tube 16 and the conduit 17 rotate to connect the guide member with the next water inlet 15. At this time, the arc-shaped stirring rod 35 enters the next filtering area 14 from the side groove 37 on the baffle 13 on one side of the filtering area 14. When the stirring rod 35 completely enters the next water inlet 15, the stirring rod 35 is connected to the next water inlet 15. When the filter area 14 is formed and the flow guide is completely connected with the next water inlet 15, the two vertical plates 38 at the bottom of the top plate 28 will be located in the side grooves 37 of the baffles 13 on both sides of the filter area 14 to close the side grooves 37, thereby reducing the flow guide being connected with the water inlet 15. After the rotating pipe 16 and the guide tube 17 stop rotating, the wastewater entering the filter area 14 carries impurities and flows from the side grooves 37 to the two adjacent filter areas 14. Through the above process, the six filter areas 14 can share one stirring rod 35, thereby reducing the waste of resources.

[0053] When the guide member is connected to the first water inlet 15, and the two vertical plates 38 at the bottom end of the top plate 28 are respectively located in the side grooves 37 on the baffles 13 on both sides of the first filter area 14, one of the vertical plates 38 will contact the blocking block 39 on the baffle 13 on one side of the first filter area 14. Then, when the rotating tube 16 and the conduit 17 rotate to connect the guide member to the second water inlet 15, the blocking block 39 can reduce the situation in which the residual wastewater in the first filter area 14 carrying impurities flows out of the side groove 37 on the baffle 13 on one side of the first filter area 14 into the filter box 2 after the vertical plate 38 is removed from the side groove 37.

[0054] like Figure 4 and Figure 8 The mounting parts include slideways 40 arranged on the baffles 13 on both sides of the filter area 14 and a slide groove 41 arranged at one end of the filter screen 6 close to the slideway 40 for the slideway 40 to slide vertically into. The purpose of this arrangement is that when the closing plate rotates away from one of the filter areas 14 and the closure of the filter area 14 is released, the filter screen 6 is pulled upward until the filter screen 6 is moved out from between the two baffles 13. At this time, the slideway 40 will slide out of the slide groove 41, and the filter screen 6 can be removed from between the two baffles 13 in the filter area 14, and the disassembly and assembly are simple.

[0055] like Figure 5 A water flow groove 42 is provided on the arc surface on the inner side of the pad 4, and the bottom end groove wall of the water flow groove 42 is connected with the bottom end of the pad 4. The purpose of this arrangement is to facilitate the water in the filter box 2 located on the side of the pad 4 away from the water flow groove 3 to flow toward the water flow groove 3 through the water flow groove 42. The top end of the filter box 2 is hinged with a cover plate 43 for closing the box opening of the filter box 2, which is simple and convenient to use.

[0056] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
