Description

Technical Field

[0001] The invention relates to the technical field of rainwater and sewage filtering, and in particular to a firmly supported rainwater and sewage filtering mechanism. Background Art

[0002] When rainwater flows through urban roofs, roads and other areas, it will carry a lot of impurities, such as leaves, garbage, suspended particles, sediment, etc. These impurities can be removed through rainwater filters to provide a clean water source for subsequent rainwater utilization. The main purpose of rainwater filtration is to remove impurities and pollutants in rainwater to improve water quality so that it can be used for a variety of non-drinking water needs, such as irrigation, cooling tower water replenishment, toilet flushing, etc.

[0003] Most existing filtering devices filter rainwater through its natural flow, but the filtering efficiency is low and the filtering effect is poor, which has certain limitations.

[0004] In order to overcome the above defects, the prior art 1 (publication number: CN106430686A, Chinese patent published on 2017-02-22) is a rainwater and sewage treatment system, including a filtering unit for treating rainwater and sewage, the filtering unit includes a primary filtering pool and a secondary filtering pool, a first filtering device with a stepped structure is arranged in the primary filtering pool, each horizontal part of the stepped structure is provided with a filtering block, each vertical part of the stepped structure is provided with a baffle, the filtering block is detachably connected to the side wall of the primary filtering pool, the stepped structure divides the primary filtering pool into a raw water chamber at the bottom and a clean water chamber at the top, and has a high removal rate for the main pollutants (SS, COD, TN, TP, NH3-N) in the rainwater and sewage, and at the same time, the processing speed is fast, which can effectively reduce the pollution of the combined pipe overflow rainwater and sewage to the receiving water body of the city. Secondly, it occupies a small area, which solves the defect that the overflow sewage treatment structure occupied a large area in the past. Furthermore, the pipeline liquid level detector is used to realize automatic operation, and the filter material can be disassembled for off-site cleaning, which is convenient for operation and maintenance.

[0005] There is also prior art 2 (publication number: CN114180669A, Chinese patent with publication date of 2022-03-15), a high-efficiency rainwater and sewage purification system that can improve filtration efficiency and is easy to maintain. The rainwater filtration tank body is arranged in an upper and lower split type, so it is convenient to maintain the equipment and can ensure the filtering effect of the equipment; the service life is improved, and a booster pump is arranged in the purification equipment to enable rainwater to be filtered quickly, thereby improving the filtration effect; finally, since a backwash pump is arranged on one side of the lower tank body, it is convenient to backwash the filter layer and clean the purification equipment.

[0006] Although the existing technologies 1 and 2 can improve the filtering effect of rainwater and sewage, the devices cannot be limited for a second time during placement. When a large amount of rainwater is poured into the filtering device, the box may topple over due to the impact of the rainwater, which has certain limitations.

[0007] Therefore, we propose a support-stabilized rainwater and sewage filtering mechanism to solve the above-mentioned problems. Summary of the invention

[0015] Preferably, the first gear and the toothed plate are meshed with each other, and the first gear forms a traction structure through a pull rope and a moving block, and the pressure plate forms a sliding structure through a box body and a movable groove.

[0016] Preferably, the clamping plates are arranged in two groups symmetrically front and back about the center point of the box body, and the inner sides of the clamping plates are designed to be in an arc shape.

[0017] Preferably, the limiting mechanism includes a second limiting rod, the second limiting rod is fixedly connected to the inside of the movable groove, the moving block is nested and connected to the outside of the second limiting rod, and a second spring is fixedly connected between the inner edge of the moving block and the movable groove, an air supply airbag is fixedly connected between the inner center of the moving block and the movable groove, an auxiliary airbag is fixedly connected to the inner side of the auxiliary ring, and a delivery hose is connected through the auxiliary airbag and the air supply airbag.

[0018] Preferably, the moving block forms a sliding structure through the second spring and the movable groove, the auxiliary airbag is interconnected with the air supply airbag through the delivery hose, and the inner diameter of the auxiliary ring is greater than the maximum outer diameter of the box body.

[0019] Preferably, the upper surface of the pressure plate is fixedly connected to a twisted rod, and the twisted rod is threadedly connected to the inner side of the threaded sleeve, and the inner side of the box body is nested with a second gear, and a torsion spring is fixedly connected between the lower surface of the second gear and the interior of the box body, and the upper surface of the second gear is fixedly connected to a rotating shaft, and the upper end of the rotating shaft is fixedly connected to a cam, and the second gear and the half gear are meshed with each other.

[0021] Preferably, the baffle plate corresponds to the position of the discharge hole one by one, a one-way valve flap is provided inside the discharge hole, and the baffle plate forms a sliding structure with the medicine box through a return spring.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The supporting legs can provide preliminary support for the box. When rainwater flows into the box, the box, under the action of its own gravity, drives the slider to move along the first limit rod. When the slider moves downward, it squeezes the first spring. At this time, the first spring undergoes elastic deformation. The elastic force of the first spring itself can buffer the downward movement of the box, thereby reducing the impact of the rainwater on the box.

[0024] When the box moves downward, its bottom will contact with the pressure plate and drive the pressure plate to move downward synchronously. At this time, the pressure plate will drive the tooth plate to move downward, so that the tooth plate drives the first gear meshing with it to rotate. When the first gear rotates, its shaft end will reel in the pull rope, and the pull rope will slowly reel in, thereby pulling the moving block, so that the moving block drives the clamping plate to move toward each other. The side of the box can be clamped and supported by the clamping plate, so that the box is placed more stably;

[0025] When the moving block drives the clamping plates to move toward each other, the moving block will move along the second limiting rod to stably squeeze the air supply airbag. When the air supply airbag is squeezed, the gas inside it will be transported to the auxiliary airbag through the delivery hose, so that the auxiliary airbag will expand. The inner side of the expanded auxiliary airbag contacts the outer side of the box body, thereby further limiting the upper side of the box body and better supporting the box body.

[0026] When the box body moves downward, it will drive the threaded sleeve to rotate along the outer side of the twisted rod. At this time, the threaded sleeve rotates under the action of the threaded connection, thereby synchronously driving the half gear to rotate. When the half gear rotates, it will drive the second gear to rotate. At the same time, when the second gear is not engaged with the half gear, the second gear will rotate and reset under the elastic force of the torsion spring. The reciprocating second gear will synchronously drive the cam to rotate through the rotating shaft. At this time, the cam will knock on the inner wall of the box body, causing the box body to vibrate. The vibrating box body can further filter rainwater quickly on the filter plate.

[0027] When the half gear rotates, it will drive the medicine box to rotate synchronously. At this time, the baffle will move outward under the action of centrifugal force. At the same time, the movement of the baffle can be limited by the docking rod. The baffle moves outward and does not fit the discharge hole. At this time, the medicine inside the medicine box can be discharged outward synchronously by the centrifugal force and enter the interior of the box to further filter the rainwater inside the box.

[0041] A bottom plate 1, an extension platform 2 is fixedly connected to the upper surface of the bottom plate 1, and support legs 3 are fixedly connected to the left and right sides of the bottom plate 1, and a box body 4 is arranged inside the support legs 3, and a filter plate 12 is fixedly connected to the upper side of the inner part of the box body 4;

[0042] The movable groove 15 is provided inside the extension platform 2, and the movable groove 15 is nested with a moving block 20, and the upper surface of the moving block 20 is fixedly connected with a clamping plate 6, and a driving mechanism that can drive the clamping plate 6 to move and clamp is provided between the inner side of the moving block 20 and the movable groove 15;

[0043] The driving mechanism includes a slider 7, which is fixedly connected to the side of the box body 4 and is arranged inside the supporting leg 3. The first limiting rod 9 is fixedly connected inside the supporting leg 3. The slider 7 is nested and connected to the outside of the first limiting rod 9, and a first spring 8 is fixedly connected between the lower end of the slider 7 and the supporting leg 3. The inside of the movable groove 15 is fixedly connected to the telescopic rod 14, and the upper end of the telescopic rod 14 is fixedly connected to the pressing plate 13, and the side of the pressing plate 13 is fixedly connected to the toothed plate 27. At the same time, the inside of the movable groove 15 is nested and connected to the first gear 25, and the axial end of the first gear 25 is wound with a pull rope 19, and the other end of the pull rope 19 is fixedly connected to the inner side of the moving block 20;

[0044] The first gear 25 and the tooth plate 27 are meshed with each other, and the first gear 25 forms a traction structure with the moving block 20 through the pull rope 19, the pressure plate 13 forms a sliding structure with the movable groove 15 through the box body 4, and the clamping plate 6 is symmetrically arranged in two groups about the center point of the box body 4, and the inner side of the clamping plate 6 is designed in an arc shape.

[0045] The box body 4 can be initially supported by the supporting legs 3. When rainwater is injected into the box body 4, the box body 4 will drive the slider 7 to move along the first limit rod 9 under the action of its own gravity. The slider 7 will squeeze the first spring 8 while moving downward. At this time, the first spring 8 will undergo elastic deformation. The elastic force of the first spring 8 itself can buffer the downward movement of the box body 4, thereby reducing the impact of the rainwater on the box body 4. When the box body 4 moves downward, its bottom will conflict with the pressure plate 13 and drive the pressure plate 13 to move downward synchronously. At this time, the pressure plate 13 will drive the tooth plate 27 to move downward, so that the tooth plate 27 drives the first gear 25 meshing therewith to rotate. When the first gear 25 rotates, its shaft end will reel in the drawstring 19, and the drawstring 19 will slowly reel in, thereby pulling the moving block 20, so that the moving block 20 drives the clamping plate 6 to move toward each other. The side of the box body 4 can be clamped and supported by the clamping plate 6, so that the box body 4 is placed more stably.

[0047] An auxiliary ring 5, the auxiliary ring 5 is fixedly connected to the upper surface of the supporting leg 3, and a limiting mechanism that can flexibly assist in limiting the box body 4 is provided between the inner side of the auxiliary ring 5 and the movable groove 15;

[0048] The limiting mechanism includes a second limiting rod 22, which is fixedly connected to the inside of the movable groove 15, and the moving block 20 is nested and connected to the outside of the second limiting rod 22, and a second spring 21 is fixedly connected between the inner edge of the moving block 20 and the movable groove 15, and an air supply airbag 17 is fixedly connected between the inner center of the moving block 20 and the movable groove 15, and an auxiliary airbag 16 is fixedly connected to the inner side of the auxiliary ring 5, and a conveying hose 18 is connected through the auxiliary airbag 16 and the air supply airbag 17, and the moving block 20 forms a sliding structure with the movable groove 15 through the second spring 21, and the auxiliary airbag 16 is connected to the air supply airbag 17 through the conveying hose 18, and the inner diameter of the auxiliary ring 5 is larger than the maximum outer diameter of the box body 4.

[0049] While the moving block 20 drives the clamping plate 6 to move toward each other, the moving block 20 will move along the second limiting rod 22 to stably squeeze the air supply bag 17. When the air supply bag 17 is squeezed, the gas inside it will be transported to the auxiliary air bag 16 through the delivery hose 18, so that the auxiliary air bag 16 will expand. The inner side of the expanded auxiliary air bag 16 contacts the outer side of the box body 4, thereby further limiting the upper side of the box body 4 and better supporting the box body 4.

[0050] Embodiment 3: Figure 2 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 The technical solution shown in the figure, the present invention provides the following technical solution: a supporting stable rainwater and sewage filtering mechanism, disclosing a discharge mechanism, through which a reagent can be added to the inside of the water body to speed up the filtering efficiency:

[0051] A twisted rod 24 is fixedly connected to the upper surface of the pressure plate 13, and the twisted rod 24 is threadedly connected to the inner side of the threaded sleeve 23. A second gear 26 is nested and connected to the inner side of the box body 4, and a torsion spring 30 is fixedly connected between the lower surface of the second gear 26 and the interior of the box body 4, and the upper surface of the second gear 26 is fixedly connected to the rotating shaft 10, and the upper end of the rotating shaft 10 is fixedly connected to the cam 11, and the second gear 26 and the half gear 28 are meshed with each other.

[0052] The threaded sleeve 23 is nested and connected at the center of the lower surface of the box body 4, and the inner upper end of the threaded sleeve 23 is fixedly connected with a half gear 28, and the upper surface of the half gear 28 is fixedly connected with a medicine box 29, and the medicine box 29 is provided with a discharge mechanism that can automatically put medicine;

[0054] When the box body 4 moves downward, the threaded sleeve 23 will be driven to rotate along the outer side of the twisted rod 24. At this time, the threaded sleeve 23 rotates under the action of the threaded connection, thereby synchronously driving the half gear 28 to rotate. When the half gear 28 rotates, it will drive the second gear 26 to rotate. At the same time, when the second gear 26 is not engaged with the half gear 28, the second gear 26 will rotate and reset under the elastic force of the torsion spring 30. The reciprocating second gear 26 will synchronously drive the cam 11 to rotate through the rotating shaft 10. At this time, the cam 11 will rotate the box body 4. The inner wall is knocked to make the box body 4 vibrate. The vibrating box body 4 can further filter the rainwater quickly on the filter plate 12. When the half gear 28 rotates, it will drive the medicine box 29 to rotate synchronously. At this time, the baffle 31 will move outward under the action of centrifugal force. At the same time, the movement of the baffle 31 can be limited by the docking rod 32. The baffle 31 moves outward and does not fit into the discharge hole 33. At this time, the medicine inside the medicine box 29 can be synchronously discharged outward by the action of centrifugal force and enter the interior of the box body 4, so as to further filter the rainwater inside the box body 4.

[0055] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
