Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a waterproof drainage device for water conservancy projects. Background Art

[0002] The waterproof drainage devices of water conservancy projects mainly utilize the waterproof performance of the waterproof layer and the drainage performance of the drainage pipes to discharge the moisture inside the building in time to prevent the moisture from damaging the building. At the same time, these devices can also effectively prevent external moisture from invading the interior of the building, ensuring the safety and stability of the building.

[0003] Most of the existing waterproof drainage devices have a simple structure. Generally, water is filtered through a filter. The filter has a low capacity for filtering impurities, and impurities such as flocs filtered out by the filter are easily blocked by impurities in the filter. The filter inside the pipe is not easy to replace and clean. The blocked filter cannot effectively filter out impurities in the water, which leads to a decline in water quality and a significant reduction in the water flow rate. At this time, if outsiders do not notice the blockage inside the pipe through the reduction in drainage volume and do not take corresponding measures, the blockage inside the pipe will gradually worsen, which means that water cannot be discharged smoothly through the pipe. Long-term poor water flow may cause the internal pressure of the pipe to increase, thereby causing damage to the pipe structure. This damage may manifest as pipe rupture, leakage or deformation, or even the entire pipe system may need to be replaced. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1.

This design not only improves the filtration efficiency and effectively captures fine impurities in the water flow, but also greatly extends the cleaning cycle of the filter net and reduces the inconvenience caused by frequent cleaning.

[0023] Through the above technical scheme, during the use of the waterproof drainage device, water flows into the water flow pipe 1 from the port near the booster pump 2. During the drainage and filtering process of the water flow, the first valve 3 and the fourth valve 6 need to be opened first, and the second valve 4 and the third valve 5 need to be closed at the same time. At this time, the water flow will enter from the top of the filter cartridge 7, and after being filtered by the cylindrical filter frame 20 and the filter screen 19 on the flow isolation annular plate 13, floccules and other impurities will be filtered and separated by the filter screen 19 and the cylindrical filter frame 20. The filtered water flow will be discharged from the bottom of the filter cartridge 7 (that is, on the one hand, it is discharged through the connecting pipe 8, and on the other hand, it is discharged through the three groups of branch pipes 17), and finally discharged from the port of the water flow pipe 1 near the fourth valve 6. As the impurities accumulated on the cylindrical filter frame 20 and the filter screen 19 gradually increase, the impurity accumulation alarm mechanism will be triggered, thereby reminding outsiders to perform impurity cleaning operations, that is, close the first valve 3 and the fourth valve 6, and open the second valve 4 and the third valve 5 at the same time. The water flows from bottom to top to backwash the impurities on the filter screen 19 and the cylindrical filter frame 20. The impurities attached to the cylindrical filter frame 20 and the filter screen 19 can be further cleaned in conjunction with the tarpaulin retracting and unfolding mechanism, the magnetic suction mechanism and the diversion sputtering mechanism, so that the impurities are discharged from the port of the water flow pipe 1 near the second valve 4 along with the water flow. It should be particularly noted that when performing the backwashing operation, the main valve 10 and the branch valve 18 need to be opened and closed at an appropriate time.

[0024] Specifically, the flow splitting support mechanism includes three groups of nozzles 14 evenly arranged on the flow dividing annular plate 13 , each of which is provided with a plurality of nozzle holes 15 with different inclination angles, and the bottoms of the three groups of nozzles 14 are fixedly connected with branch bellows 16 .

[0025] Through the above technical scheme, three groups of nozzles 14 are evenly distributed on the flow-isolating annular plate 13, and the inclined spray holes 15 on the nozzles 14 are designed to disperse the pressure of the water flow when the water flows downward, so that the water flow can be discharged through the connecting pipe 8 while flowing into the three groups of branch pipes 17 through the three groups of branch bellows 16, and finally flow back to the water flow pipe 1. When the water flow is sprayed upward for backwashing operation, the inclined spray holes 15 are used to cooperate with the diversion sputtering mechanism to change the splashing direction of the water flow so that it splashes onto the outer surface of the cylindrical filter frame 20, so as to "flush away" impurities attached to the surface of the cylindrical filter frame 20.

[0026] Specifically, the bottom end of the filter cartridge 7 is fixedly connected to a branch pipe 17, and there are three groups of branch pipes 17. The tops of the three groups of branch pipes 17 are respectively fixedly connected to the bottoms of the corresponding branch bellows 16, and the bottoms of the three groups of branch pipes 17 are fixedly connected to the water flow pipe 1, and branch valves 18 are provided on the three groups of branch pipes 17.

[0027] Through the above technical solution, the function of the three groups of branch pipes 17 is to cooperate to provide stable support for the filter cartridge 7 so that it can be stably connected to the water pipe 1 system, which can disperse the pressure of the water flow, or perform backwashing operations through their cooperation. In addition, a potential function of the three groups of branch pipes 17 is to play a certain limiting role on the I-shaped tube 11, thereby preventing the main corrugated tube 12 from being too tortuous in the horizontal direction during deformation, which affects the position adjustment of the lower rubber head 25 by the I-shaped tube 11.

[0028] Specifically, the impurity accumulation alarm mechanism includes an inclined strip plate 22 fixedly connected to the outer surface of the filter cartridge 7 , and a through shaft 23 is fixedly penetrated through the bottom end of the inclined strip plate 22 .

[0029] Through the above technical solution, when the wing-shaped strip 24 rotates along the through shaft 23, the positions of the upper glue head 26 and the lower glue head 25 thereon will change accordingly.

[0030] Specifically, the outer surface of the through shaft 23 is rotatably connected with a wing-shaped strip 24 , and the bottom end and the top end of the wing-shaped strip 24 are respectively provided with a lower rubber head 25 and an upper rubber head 26 .

[0031] Through the above technical solution, the upper rubber head 26 and the lower rubber head 25 are both made of rubber material and have a certain flexible deformation ability. When the I-shaped tube 11 is moving downward, its I-shaped design will push the lower rubber head 25, so that the upper rubber head 26 of the wing-shaped strip 24 gradually approaches the switch 29 position of the power supply 27.

[0032] Specifically, a power source 27 is fixedly mounted on the outer surface of the filter cartridge 7 , an alarm light 28 is electrically connected to the top of the power source 27 , and a switch 29 is provided on the power source 27 .

[0033] Through the above technical solution, when the glue head 26 contacts the switch 29, it will trigger the alarm light 28, allowing the power supply 27 to power the alarm light 28, so that the alarm light 28 produces a flashing light and a harsh alarm sound, so as to intuitively warn outside staff of the blockage in the filter cylinder 7.

[0034] Specifically, the tarpaulin folding and unfolding mechanism includes a storage groove 30 opened at the bottom end of the funnel 21, a tarpaulin cover 31 is arranged in the storage groove 30, the bottom of the tarpaulin cover 31 is fixedly connected with an iron ring 32, the top of the iron ring 32 is fixedly connected with a storage spring 33, and the top of the storage spring 33 is fixedly connected to the bottom of the funnel 21, the top of the iron ring 32 is fixedly connected with a push rod 34, and the push rod 34 is movably arranged with the funnel 21 and the top of the filter cartridge 7 respectively.

[0035] Through the above technical solution, the canopy 31 is made of polyvinyl chloride waterproof material. Under normal circumstances, the storage spring 33 will pull the iron ring 32 upward, so that most of the canopy 31 can be stored in the storage groove 30. It is worth mentioning that the push rod 34 passing through the filter cartridge 7 and the funnel 21 is made of rubber material and has a certain flexible deformation ability. During the process of passing through the filter cartridge 7 and moving, it can ensure that the filter cartridge 7 is in a well-sealed state.

[0036] Specifically, the magnetic attraction mechanism includes a lower annular groove 35 formed on the top of the flow isolation annular plate 13 , and the outer diameter of the lower annular groove 35 is consistent with the outer diameter of the iron ring 32 . A magnet 36 is disposed in the lower annular groove 35 .

[0037] Through the above technical solution, when the push rod 34 is pushed down to move the iron ring 32 downward until it contacts the magnet 36 , the iron ring 32 can be firmly adsorbed and stuck in the lower ring groove 35 under the strong adsorption effect of the magnet 36 .

[0038] Specifically, the flow-guiding sputtering mechanism includes an annular frame 37 arranged on the inner wall of the filter cartridge 7 , and an arc shaft 38 is fixedly connected to the annular frame 37 . There are three arc shafts 38 , and the outer surfaces of the three arc shafts 38 are rotatably connected to flow-guiding arc plates 39 .

[0039] Through the above technical solution, the annular frame 37 is fixedly arranged. During the process of the flow-isolating annular plate 13 moving the cylindrical filter frame 20 up and down, a relative misalignment will occur between the cylindrical filter frame 20 and the guide arc plate 39. During this process, the guide arc plate 39 can change the water flow sprayed upward from the nozzle 14 and make it splash to different positions on the outer surface of the cylindrical filter frame 20.

[0040] Specifically, a guide groove 40 is opened on the inner side of the guide arc plate 39 , and a plurality of groups of evenly distributed soft springs 41 are arranged on the annular frame 37 , and one end of the soft spring 41 away from the annular frame 37 is fixedly connected to the outer surface of the guide arc plate 39 .

[0041] Through the above technical scheme, the guide groove 40 on the guide arc plate 39 is designed to allow the water flow to be blocked by the inclined guide arc plate 39 when it is sprayed upward through the nozzle 14 through the nozzle hole 15 inclined thereon, thereby cooperating with the guide groove 40 to change the sputtering direction of the water flow, and the design of the soft spring 41 is to allow the guide arc plate 39 to rotate to a certain extent along the arc axis 38 (i.e., the inclination changes) when the impact pressure of the water flow changes, thereby further expanding the sputtering range of the water flow.

[0042] Working principle: When filtering water flow, the waterproof drainage device must first open the first valve 3 and the fourth valve 6, and close the second valve 4 and the third valve 5. The water flows into the water pipe 1 from the port near the booster pump 2. At this time, the direction of the water flow in the pipeline system is that after the water flows through the booster pump 2 (the booster pump 2 can be turned on when needed), it will be blocked by the third valve 5 and the second valve 4. Therefore, the water will pass through the first valve 3 and then enter the filter cartridge 7. After entering the filter cartridge 7, the water will pass through the funnel 21 and enter the columnar area formed by the cylindrical filter frame 20 and the filter screen 19. In the process of filtering the water flow by the filter screen 19 and the cylindrical filter frame 20, impurities such as flocs in the water flow will be filtered out. On the filter screen 19 and the cylindrical filter frame 20, compared with the filtering method of only filtering through the filter screen 19, this filtering method of the filter screen 19 combined with the cylindrical filter frame 20 can filter out impurities with a larger capacity, and a part of the filtered water flow passes through the filter screen 19 and is discharged downward from the connecting pipe 8, and then passes through the I-shaped pipe 11 and then flows back to the water flow pipe 1 through the main bellows 12, while the other part of the water flow, after being filtered by the cylindrical filter frame 20, will pass through the cylindrical filter frame 20 and enter the flow isolation annular plate 13, and flow downward from the multiple spray holes 15 opened on the three groups of nozzles 14 into the branch bellows 16, and then flow back to the water flow pipe 1 from the corresponding branch pipe 17, and finally be discharged from the port of the water flow pipe 1 near the fourth valve 6. It should be noted that, during the filtering process, the main valve 10 on the connecting pipe 8 and the branch valves 18 on the three groups of branch pipes 17 are all in the open state. When the impurities accumulated by the filter screen 19 and the cylindrical filter frame 20 gradually increase, the weight borne by the flow-isolating annular plate 13 will become larger and larger. At this time, the flow-isolating annular plate 13 will drive the connecting pipe 8 to move downward gradually, during which the outer sleeve spring 9 is gradually compressed downward, and the I-shaped pipe 11 at the bottom of the connecting pipe 8 will also move downward synchronously, and squeeze the main bellows 12 to cause it to produce corresponding deformation. At the same time, the three groups of branch bellows 16 will also be synchronously subjected to the downward squeezing force from the flow-isolating annular plate 13, and cause them to produce corresponding deformation. In the process of the I-shaped pipe 11 moving downward, it will gradually move downward. The lower rubber head 25 is gradually pushed against, so that the wing-shaped strip 24 rotates along the through shaft 23. During this period, the upper rubber head 26 on the top of the wing-shaped strip 24 will gradually approach the power supply 27, so that the upper rubber head 26 contacts and presses on the switch 29. At this time, the power supply 27 will supply power to the alarm light 28, so that the alarm light 28 will generate an alarm, that is, the alarm light 28 will generate a harsh alarm sound while emitting a flashing light, so as to intuitively remind the outside staff that there are too many impurities in the filter cartridge 7 and they need to be cleaned in time, otherwise it is easy to affect the normal operation of the device. At this time, after receiving the alarm, the outside staff must first close the first valve 3 and open the third valve 5 and the fourth valve 6 to discharge the residual water in the filter cartridge 7 as much as possible downward. It should also be noted thatAt this time, the third valve 5 and the fourth valve 6 can be opened to allow the water that has fallen into the water flow pipe 1 (located in the area of ​​the water flow pipe 1 between the third valve 5 and the fourth valve 6) to rush out from the fourth valve 6 (at this time, it is necessary to pay attention to the pressure supply of the booster pump 2 to the water flow, so that the water flow can directly enter the left opening of the water flow pipe 1 and pass through the third valve 5 and the fourth valve 6 in turn, and there is no need for excessive pressure to allow it to enter the filter cartridge 7), so that the filtered water flow can be rushed out from the fourth valve 6, and then the push rod 34 is manually moved downward to allow the iron ring 32 to gradually approach the magnet 36 until the two are completely in contact, and the magnet 36 will tightly adsorb the iron ring 32. During the downward movement of the iron ring 32, it will pull the canopy 31 to gradually unfold downward in the storage groove 30 until the canopy 31 It is completely attached to the outer periphery of the cylindrical filter frame 20 to prevent impurities from being brought into other parts of the system by the water flow during backwashing. During this period, the storage spring 33 is pulled accordingly (the elastic force of the storage spring 33 is smaller than the magnetic force of the magnet 36, ensuring that the magnet 36 and the iron ring 32 will not separate during the backwashing process). Then, the first valve 3 and the fourth valve 6 are closed while the second valve 4 and the third valve 5 are opened to change the direction of the water flow. It should be noted that at this time, all the branch valves 18 on the three groups of branch pipes 17 should be closed first, and only the main valve 10 should be opened. Then, during the process of water flowing in the water flow pipe 1, due to the obstruction of the first valve 3 and the fourth valve 6, it can only enter from the bottom of the filter cartridge 7 and flow into the water flow pipe 1 from the top, and finally from The water pipe 1 is discharged from the port near the second valve 4. In this process, the impurities in the filter cartridge 7 are backwashed and cleaned by the water flow. In the process of backwashing the filter screen 19, the water flow directly enters through the main bellows 12, the I-shaped pipe 11 and the connecting pipe 8, and impacts upward on the impurities such as floccules accumulated on the filter screen 19, thereby flushing out the impurities accumulated on the filter screen 19 together with the water flow. In this process, since some impurities are also attached to the cylindrical filter frame 20, it is difficult for them to be flushed out of the filter cartridge 7 along with the straight upward water flow. Therefore, a tarpaulin retracting and unfolding mechanism, a magnetic suction mechanism and a diversion sputtering mechanism are designed. At this time, the push rod 34 needs to be pulled upward to allow the iron ring 32 and the magnet 36 to be out of the adsorption state, so that the elastic force of the storage spring 33 Under the action, the canopy 31 moves upward to reset, that is, the canopy 31 is no longer sleeved on the outer periphery of the cylindrical filter frame 20. Next, the main valve 10 can be closed and the three sets of branch valves 18 can be opened. In the process of the water flow passing through the three sets of branch pipes 17 and rushing upward, it will be sprayed upward through the corresponding nozzles 14, and the multiple inclined spray holes 15 on the nozzles 14 are designed to allow the water flow to be sprayed onto the guide arc plate 39 in different directions. With the inclined design of the guide arc plate 39, the water flow can be sprayed through the guide groove 40 on the guide arc plate 39 (here, the guide arc plate 39 cooperates with the guide groove 40 to guide the water flow), that is, the redirected water flow can splash onto the surface of the cylindrical filter frame 20, thereby "flushing away" the impurities attached to the cylindrical filter frame 20.Allow impurities to fall into the filter screen 19, and then repeat the above-mentioned backwashing operation of the filter screen 19 to flush the impurities that fall on the filter screen 19 out of the filter cartridge 7. At the same time, in order to increase the flushing range of the cylindrical filter frame 20, the booster pump 2 can be used to change the impact force of the water flow, so that the water flow impacts the guide arc plate 39 with different forces. At this time, the soft spring 41 will make a corresponding deformation, and at the same time, the guide arc plate 39 is rotated to a certain extent along the arc axis 38 (that is, the inclination of the guide arc plate 39 is changed), so that the water flow is sprayed onto the guide arc plate 39, and then splashed to different positions on the outer surface of the cylindrical filter frame 20 through the guide groove 40, which significantly increases the flushing range and improves the thoroughness and comprehensiveness of the impurity flushing (it should be particularly noted that in the process of backwashing the filter screen 19, the water quality connected to the port of the water flow pipe 1 close to the booster pump 2 must be a clean water source, such as tap water).

[0043] In summary, the waterproof drainage device has achieved significant improvements in filtration efficiency, intelligent monitoring and early warning, cleaning mechanism, adjustability and safety performance. These advantages are not only reflected in the stability and reliability of daily operation, but also in the long run. It helps to reduce maintenance costs and improve system life, and provide users with more efficient, safe and economical drainage solutions. At the same time, the device is also highly flexible and scalable, and can be customized and optimized according to the actual needs of users to meet the needs of diverse application scenarios.
