Description

Technical Field

[0001] The present invention relates to the technical field of flood control and drainage devices, and in particular to a trailer-type flood control and drainage device. Background Art

[0002] At present, when preventing floods and draining water, a large number of sandbags are usually piled up to block the flood, and then water pumps are used to pump out the water. Carrying sandbags consumes a lot of manpower and is very inconvenient. In addition, since there are a large amount of solid impurities, garbage, etc. in the flood, these large garbage and impurities enter the water pump and are easily stuck inside the water pump, causing damage to the water pump. The existing ones usually set a filter at the water inlet to filter out the garbage and impurities, but as the pumping proceeds, a large amount of garbage and impurities will adhere to the surface of the filter, causing the filter to be blocked, thereby causing the pumping efficiency to become lower and lower, and most of the water inlets are usually set at low water levels, and manual work cannot clean the filter in time. Therefore, when the filter is seriously blocked for a long time, the water pump will be overloaded, causing the water pump to burn out.

[0017] Preferably, four mounting grooves are provided at the lower end of the carrier, a universal wheel is slidably mounted on the inner wall of each mounting groove, a hydraulic cylinder is fixedly connected to the top of each mounting groove, and the movable end of the hydraulic cylinder is fixedly connected to the universal wheel.

[0018] The present invention has the following beneficial effects:

[0019] 1. By setting up a cleaning mechanism, during the process of pumping and draining, the scraper moves back and forth in the water inlet to scrape off the impurities and garbage adhering to the filter screen, thereby preventing the garbage and impurities adhering to the filter screen from becoming more and more, causing serious blockage of the filter screen, thereby greatly reducing the efficiency of pumping and draining, and avoiding damage caused by overload of the pump. The filter screen can be continuously cleaned during the drainage process without manual cleaning, which is more convenient.

[0020] 2. By setting a driving mechanism, when the scraper moves back and forth, it will drive multiple brushes to move, clean the filter, and improve the cleaning ability of the filter, and the gears will also move synchronously. Since one of the gears is meshed with the rack, the gears will rotate synchronously, driving multiple rotating rods to rotate, so that the multiple brushes can also rotate when they move back and forth, thereby further improving the cleaning ability, and the rotation of the rotating rod will drive multiple crushing knives to rotate, and the crushing knives will crush the impurities and garbage, crushing them into smaller pieces, reducing their adhesion to the surface of the filter. When the volume of the crushed impurities and garbage is smaller than the mesh diameter of the filter, they can pass through the filter and be discharged through the suction pipe, water pump and drainage pipe with the water flow. Because when the volume of garbage and impurities is small enough to pass through the mesh of the filter, they cannot cause clogging of the water pump, and will no longer damage the water pump. Therefore, the filter can be cleaned and the garbage and impurities can be processed and discharged at the same time, thereby avoiding repeated attachment of garbage and impurities to the surface of the filter, causing continuous clogging, and further improving the drainage capacity;

[0021] 3. By setting a flow sensor, when there is a large amount of impurities and garbage or a large amount of impurities and garbage flows into the water pumping port in a short time, the large impurities and garbage need to be scraped back and forth many times to be completely broken, and then the filter will be quickly blocked in a short time, causing the water flow in the pumping pipe to drop significantly, or a large amount of impurities and garbage flows in a short time, making it impossible to discharge quickly in a short time, which will also cause the filter to be quickly blocked in a short time, causing the water flow in the pumping pipe to drop significantly. When the above situation occurs, the flow sensor will detect that the flow in the pumping pipe has dropped significantly, and when it lasts for more than one minute, the flow sensor will transmit a signal, and the PLC control circuit will control the delay switch to be disconnected. The delay switch will automatically close after being disconnected for three minutes. When the delay switch is disconnected, the water pump will be powered off and stop pumping water, because the filter is seriously clogged at this time and cannot be cleaned in a short time. Stopping the water pump can prevent the water pump from being overloaded and burned for a long time, and protect the water pump. During the stop of the water pump, the scraper is still moving back and forth, driving the crushing knife to rotate, cleaning and crushing the garbage and impurities, thereby reserving time for processing the garbage and impurities;

[0022] 4. By setting up an auxiliary drainage mechanism and a trigger mechanism, when the water pump stops, the electromagnet will be energized to generate magnetic repulsion, pushing the magnetic column into the slot, and then the rotation of the helical gear ring can drive the second helical gear to rotate, drive the hollow rotating rod to rotate, and thus drive the second reciprocating screw to rotate, drive the slider to slide in the auxiliary drainage chamber, and the slider will drive the slide plate to slide back and forth through the connecting rod, and then some garbage impurities and water in the water suction port will be sucked into the auxiliary drainage chamber through the one-way water inlet pipe, and then the garbage impurities and water in the auxiliary drainage chamber will enter the drainage pipe through the one-way drainage pipe, and finally be discharged through the drainage pipe. Therefore, during the period when the water pump stops, some garbage and water in the water suction port can still be discharged, which not only increases the cleaning capacity of garbage impurities, but also enables the drainage to continue, thereby ensuring the drainage efficiency;

[0023] 5. The water pump will automatically shut down when the filter is severely clogged to prevent the water pump from overloading and burning. At this time, auxiliary drainage will be turned on, and the servo motor will be used to drive the slide to slide back and forth. The load of the servo motor will increase at this time, but it will only increase for three minutes and will not cause a major impact on the servo motor. Therefore, during the entire drainage process, the water pump and the servo motor will alternate to drain water, which can ensure uninterrupted drainage and improve drainage efficiency. It can also prevent the water pump and the servo motor from being overloaded for a long time, effectively protecting the water pump and the servo motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Reference Figures 1-9 A trailer-type flood control and drainage device includes a carrier 1, a water inlet 2 is opened on the side wall of the carrier 1, a water pump 3 is fixedly connected to the upper end of the carrier 1, the water inlet of the water pump 3 is connected to the water inlet 2 through a water pump pipe 4, the discharge port of the water pump 3 is fixedly connected to a drainage pipe 5, and a filter 6 is fixedly connected to the inner wall of the water inlet 2;

[0036] Furthermore, the water pump 3 is started. Under the action of the water pump 3, water can enter the water pump pipe 4 through the water pump port 2, and then the water will be discharged to the other side of the carrier 1 through the drainage pipe 5, thereby quickly draining water. When the water flows through the water pump port 2, impurities and garbage in the water will be intercepted by the filter 6, thereby preventing impurities and garbage from entering the water pump 3 and blocking the water pump 3, thereby avoiding damage to the water pump 3.

[0037] The cleaning mechanism includes a first chute 7 provided on the inner wall of the water inlet 2, and a scraper 8 (such as Figure 9 As shown in the figure, one end of the scraper 8 is fitted with the surface of the filter screen 6, and two sewage storage tanks 9 are symmetrically provided on the inner wall of the water suction port 2. Two mounting cavities 10 are symmetrically provided in the scraper 8. The inner walls of the two mounting cavities 10 are rotatably connected to a plurality of rotating rods 11, wherein one end of some rotating rods 11 passes through the side wall of the scraper 8 and is fixedly connected to a circular plate 12 (the two rotating rods 11 at the bottom are not fitted with the circular plate 12 and only serve to transmit torque), a plurality of bristles 13 are fixedly connected to the side wall of the circular plate 12, and the plurality of bristles 13 are fitted with the surface of the filter screen 6, and a plurality of crushing knives 14 are fixedly connected to the side walls of some rotating rods 11;

[0038] A driving mechanism is installed in the first sliding groove 7 .

[0039] The driving mechanism includes a first reciprocating screw 15 rotatably connected to the inner wall of the first slide groove 7, the side wall of the first reciprocating screw 15 is threadedly connected to the scraper 8, a cavity 16 is opened in the carrier 1, and a rotating shaft 17 is rotatably connected to the top of the cavity 16. The lower end of the rotating shaft 17 is fixedly connected to a disc 18, and the lower end of the disc 18 is fixedly connected to a bevel gear ring 19. One end of the first reciprocating screw 15 extends into the cavity 16 and is fixedly connected to a first bevel gear 20. The first bevel gear 20 is meshed with the bevel gear ring 19. A servo motor 21 is fixedly connected to the upper end of the carrier 1, and the output end of the servo motor 21 passes through the upper end of the carrier 1 and is fixedly connected to the rotating shaft 17.

[0040] The driving mechanism also includes a second chute 22 opened at the bottom of the water suction port 2, the side wall of the scraper 8 is slidably connected to the inner wall of the second chute 22, the inner wall of the second chute 22 is fixedly connected to a rack 23, and the side walls of multiple rotating rods 11 located in the installation cavity 10 are all fixedly connected to gears 24, and the gears 24 are meshed with each other, and one of the gears 24 is meshed with the rack 23.

[0041] Furthermore, when the scraper 8 moves back and forth, it will synchronously drive the multiple circular plates 12 to move, and then drive the multiple brushes 13 to move, to clean the filter 6, and improve the cleaning ability of the filter 6, and the gear 24 will also move synchronously. Since one of the gears 24 is engaged with the rack 23, the gear 24 will rotate synchronously, so that the other gears 24 will rotate, driving the multiple rotating rods 11 to rotate, thereby driving the circular plates 12 to rotate, so that the multiple brushes 13 can also rotate when reciprocating, thereby further improving the cleaning ability, and the rotation of the rotating rod 11 will drive the multiple crushing knives 14 to rotate, and the crushing knives 14 will crush the impurities and garbage, crush them into smaller pieces, and reduce their adhesion to the surface of the filter 6. Due to the continuous operation of the water pump 3, even if the garbage and impurities will be pushed into the sewage storage tank 9, Under the action of the water pump 3, some impurities and garbage will still flow out of the sewage storage tank 9 with the water flow and continue to attach to the filter 6. However, due to the presence of the crushing knife 14, when the scraper 8 moves back and forth to push the garbage and impurities, the crushing knife 14 will also crush them synchronously. When the volume of the crushed impurities and garbage is smaller than the mesh aperture of the filter 6, they can pass through the filter 6 and be discharged through the water pipe 4, the water pump 3 and the drainage pipe 5 with the water flow. Because when the volume of garbage and impurities is small enough to pass through the mesh of the filter 6, they cannot cause blockage to the water pump 3, and will no longer cause damage to the water pump 3. Therefore, the garbage and impurities can be processed and discharged while the filter 6 is being cleaned, thereby avoiding the repeated attachment of garbage and impurities to the surface of the filter 6, causing continuous blockage, and the drainage capacity can be further improved.

[0042] The scraper 8 is located in the first slide groove 7 and has two first baffles 25 symmetrically fixedly connected to the side wall, and the side walls of the two first baffles 25 are sealed and slidably connected to the inner wall of the first slide groove 7. Two first transverse grooves 26 are symmetrically opened in the carrier 1, and the two first baffles 25 are respectively sealed and slidably connected to the inner walls of the two first transverse grooves 26. The scraper 8 is located in the second slide groove 22 and has two second baffles 27 symmetrically fixedly connected to the side wall, and the side walls of the two second baffles 27 are both sealed and slidably connected to the inner wall of the second slide groove 22. Two second transverse grooves 28 are symmetrically opened in the carrier 1, and the two second baffles 27 are respectively sealed and slidably connected to the inner walls of the two second transverse grooves 28.

[0043] It should be noted that the first baffle 25 and the second baffle 27 can prevent garbage and impurities from entering the first chute 7 and the second chute 22, thereby preventing the garbage and impurities from affecting the rotation of the first reciprocating screw 15 and the gear 24.

[0044] The inner wall of the water pumping pipe 4 is provided with a flow sensor 29 (such as Figure 4 As shown), the flow sensor 29, the water pump 3 and the external delay switch are connected through a PLC control circuit.

[0045] Furthermore, when there is a large volume of impurities and garbage or a large amount of impurities and garbage flows into the water pumping port 2 in a short time, the large impurities and garbage need to be scraped back and forth multiple times before they can be completely broken, and then the filter screen 6 will be quickly blocked in a short time, causing the water flow in the water pumping pipe 4 to drop significantly, or a large amount of impurities and garbage flows in a short time, which cannot be quickly discharged in a short time, and the filter screen 6 will be quickly blocked in a short time, causing the water flow in the water pumping pipe 4 to drop significantly. When the above situation occurs, the flow sensor 29 will detect that the flow in the water pumping pipe 4 has been greatly reduced. , and when it lasts for more than one minute, the flow sensor 29 will transmit a signal, and the PLC control circuit will control the delay switch to be disconnected. The delay switch will automatically close after being disconnected for three minutes. When the delay switch is disconnected, the water pump 3 will be powered off and stop pumping water, because the filter 6 is seriously clogged at this time and cannot be cleaned in a short time. Stopping the water pump 3 can prevent the water pump 3 from being overloaded and burned for a long time, and protect the water pump 3. During the period when the water pump 3 is stopped, the scraper 8 is still moving back and forth, driving the crushing knife 14 to rotate, cleaning and crushing the garbage and impurities, thereby reserving time for processing the garbage and impurities.

[0046] An auxiliary drainage mechanism is installed on the carrier 1, which includes an auxiliary drainage chamber 30 opened in the carrier 1. The inner wall of the auxiliary drainage chamber 30 is sealed and slidably connected with a slide plate 31. The auxiliary drainage chamber 30 is connected with the water pumping port 2 through a one-way water inlet pipe 32. The one-way water inlet pipe 32 only allows water and garbage in the water pumping port 2 to enter the auxiliary drainage chamber 30. The auxiliary drainage chamber 30 is connected with the drainage pipe 5 through a one-way drainage pipe 33. The one-way drainage pipe 33 only allows water and garbage in the auxiliary drainage chamber 30 to be discharged into the drainage pipe 5. The inner wall of the auxiliary drainage chamber 30 is slidably connected with a slide plate 34. The side wall of the slide plate 34 is symmetrically fixedly connected with two connecting rods 35, and the other ends of the two connecting rods 35 are fixedly connected to the side wall of the slide plate 31.

[0047] The auxiliary drainage mechanism also includes a second reciprocating screw 36 rotatably connected to the inner wall of the auxiliary drainage chamber 30. The side wall of the second reciprocating screw 36 is threadedly connected to the slider 34. The inner wall of the cavity 16 is rotatably connected to a hollow rotating rod 37. One end of the second reciprocating screw 36 extends to the hollow rotating rod 37 and is arranged. The side wall of the hollow rotating rod 37 is fixedly connected to a second bevel gear 38, and the second bevel gear 38 is meshed with the bevel gear ring 19.

[0048] A trigger mechanism is installed on the second reciprocating screw 36, which includes two vertical slots 39 symmetrically opened on the side wall of the second reciprocating screw 36. The inner walls of the two vertical slots 39 are slidably connected to magnetic columns 40. The inner wall of the hollow rotating rod 37 is provided with multiple slots 41 that cooperate with the magnetic columns 40. A spring 42 is fixedly connected between the inner wall of the vertical slot 39 and the magnetic column 40. An electromagnet 43 is fixedly connected to the inner wall of the vertical slot 39. The electromagnet 43, the flow sensor 29 and the delay switch are connected through a PLC control circuit.

[0049] Furthermore, when the water pump 3 is stopped, the electromagnet 43 will be energized to generate magnetic repulsion, pushing the magnetic column 40 into the slot 41. At this time, the rotation of the bevel gear ring 19 can drive the second bevel gear 38 to rotate, drive the hollow rotating rod 37 to rotate, thereby driving the second reciprocating screw 36 to rotate, and drive the slider 34 to slide in the auxiliary drainage chamber 30. The slider 34 will drive the slide plate 31 to slide back and forth through the connecting rod 35. Then, some garbage impurities and water in the water pumping port 2 are sucked into the auxiliary drainage chamber 30 through the one-way water inlet pipe 32, and then the garbage impurities and water in the auxiliary drainage chamber 30 will enter the drainage pipe 5 through the one-way drainage pipe 33, and finally be discharged through the drainage pipe 5. Therefore, when the water pump 3 is stopped, some garbage and water in the water pumping port 2 can still be discharged, which not only increases the cleaning capacity of garbage impurities, but also allows the drainage to continue, ensuring drainage efficiency.

[0050] It is worth mentioning that the water pump 3 will automatically shut down when the filter 6 is severely clogged to prevent the water pump 3 from overloading and burning. At this time, auxiliary drainage will be turned on, and the servo motor 21 will be used to drive the slide 31 to slide back and forth in a sealed manner. At this time, the load of the servo motor 21 will increase, but it will only increase for three minutes and will not have a major impact on the servo motor 21. Therefore, during the entire drainage process, the water pump 3 and the servo motor 21 will alternate to drain water, which can ensure uninterrupted drainage work and improve drainage efficiency. It can also prevent the water pump 3 and the servo motor 21 from being overloaded for a long time, effectively protecting the water pump 3 and the servo motor 21.

[0051] The upper end of the carrier 1 is symmetrically connected to two pins 44 for rotation, and the side walls of the two pins 44 are fixedly connected to water baffles 45. The upper end of the carrier 1 is symmetrically fixedly connected to two drive motors 46 through a bracket, and the output ends of the two drive motors 46 are fixedly connected to the two pins 44 respectively.

[0052] Four mounting grooves 47 are provided at the lower end of the carrier 1 , and a universal wheel 48 is slidably mounted on the inner wall of each mounting groove 47 . A hydraulic cylinder 49 is fixedly connected to the top of each mounting groove 47 , and the movable end of the hydraulic cylinder 49 is fixedly connected to the universal wheel 48 .

[0053] In the present invention, the carrier 1 can be moved to a specified position by rotating the universal wheel 48, and then the hydraulic cylinder 49 is driven to contract, driving the universal wheel 48 to move into the installation groove 47. At this time, the carrier 1 will slowly descend until the lower end of the carrier 1 is in contact with the ground, and then the drive motor 46 is driven to rotate, driving the pin shaft 44 to rotate, and then driving the two water baffles 45 to rotate, so that the two water baffles 45 are opened, and the carrier 1 can be used to block the water flow. Compared with using sandbags to pile up to block the water flow, it is more convenient and saves time and effort.

[0054] Then the water pump 3 can be started. Under the action of the water pump 3, water can enter the water pump pipe 4 through the water pumping port 2, and then the water will be discharged to the other side of the carrier 1 through the drainage pipe 5, so as to quickly drain the water. When the water flows through the water pumping port 2, the impurities and garbage in the water will be intercepted by the filter 6, thereby preventing the impurities and garbage from entering the water pump 3 and blocking the water pump 3, thereby avoiding damage to the water pump 3.

[0055] During the process of pumping and draining, the servo motor 21 is started synchronously, and the servo motor 21 will drive the rotating shaft 17 to rotate, and then drive the disc 18 to rotate, drive the bevel gear ring 19 to rotate, thereby driving the first bevel gear 20 to rotate, drive the first reciprocating screw 15 to rotate, and drive the scraper 8 to move back and forth in the water pumping port 2, and then the scraper 8 can scrape off the impurities and garbage adhering to the filter 6, and push it into the sewage storage tank 9 on both sides, so as to avoid more and more garbage and impurities adhering to the filter 6, causing serious blockage of the filter 6, and thus greatly reducing the efficiency of pumping and draining, and also avoid the overload of the water pump 3 when the filter 6 is seriously blocked, causing damage to the water pump 3. The filter 6 can be continuously cleaned during the drainage process without manual cleaning, which is more convenient.

[0056] In addition, when the scraper 8 moves back and forth, it will synchronously drive the multiple circular plates 12 to move, and then drive the multiple brushes 13 to move, to clean the filter 6, and improve the cleaning ability of the filter 6, and the gear 24 will also move synchronously. Since one of the gears 24 is engaged with the rack 23, the gear 24 will rotate synchronously, so that the other gears 24 will rotate, driving the multiple rotating rods 11 to rotate, thereby driving the circular plates 12 to rotate, so that the multiple brushes 13 can also rotate when reciprocating, thereby further improving the cleaning ability, and the rotation of the rotating rod 11 will drive the multiple crushing knives 14 to rotate, and the crushing knives 14 will crush the impurities and garbage, crush them into smaller pieces, and reduce their adhesion to the surface of the filter 6. Due to the continuous operation of the water pump 3, even if the garbage and impurities will be pushed into the sewage storage tank 9, during the extraction, Under the action of the water pump 3, some impurities and garbage will still flow out of the sewage storage tank 9 with the water flow and continue to attach to the filter 6. However, due to the presence of the crushing knife 14, when the scraper 8 moves back and forth to push the garbage and impurities, the crushing knife 14 will also crush them synchronously. When the volume of the crushed impurities and garbage is smaller than the mesh aperture of the filter 6, they can pass through the filter 6 and be discharged through the water pipe 4, the water pump 3 and the drainage pipe 5 with the water flow. Because when the volume of the garbage and impurities is small enough to pass through the mesh of the filter 6, they cannot cause blockage to the water pump 3, and will no longer cause damage to the water pump 3. Therefore, the garbage and impurities can be processed and discharged while the filter 6 is being cleaned, thereby avoiding the garbage and impurities from repeatedly adhering to the surface of the filter 6 and causing continuous blockage, which can further improve the drainage capacity.

[0057] In addition, when there is large-volume impurity garbage or a large amount of impurity garbage flows into the water pumping port 2 in a short period of time, the large-volume impurities and garbage require the scraper 8 to reciprocate multiple times to be completely crushed, and then the filter screen 6 will be quickly blocked in a short period of time, causing the water flow in the water pumping pipe 4 to drop significantly, or a large amount of impurities and garbage flows in a short period of time and cannot be quickly discharged in a short period of time, which will also cause the filter screen 6 to be quickly blocked in a short period of time, causing the water flow in the water pumping pipe 4 to drop significantly. When the above situation occurs, the flow sensor 29 will detect that the flow in the water pumping pipe 4 has dropped significantly, and when the duration exceeds one minute, the flow sensor 29 will transmit a signal, and the PLC control circuit will control the delay switch to be disconnected. The delay switch will automatically close after being disconnected for three minutes. When the delay switch is disconnected, the water pump 3 will be powered off and stop pumping water, because the filter screen 6 is seriously blocked at this time and cannot be cleaned in a short period of time. Stopping the water pump 3 can prevent the water pump 3 from being overloaded and burned for a long time, protect the water pump 3, and during the stop of the water pump 3, the scraper 8 is still moving back and forth, driving the crushing knife 14 rotates to clean and crush the garbage and impurities, thereby reserving time for processing the garbage and impurities. At this time, the electromagnet 43 will be energized to generate magnetic repulsion, pushing the magnetic column 40 into the card slot 41. At this time, the rotation of the helical gear ring 19 can drive the second helical gear 38 to rotate, drive the hollow rotating rod 37 to rotate, and then drive the second reciprocating screw 36 to rotate, drive the slider 34 to slide in the auxiliary drainage chamber 30, and the slider 34 will drive the slide plate 31 to slide back and forth through the connecting rod 35. Then, some garbage, impurities and water in the water inlet 2 pass through the single The garbage and water in the auxiliary drainage chamber 30 are drawn into the water inlet pipe 32, and then the garbage, impurities and water in the auxiliary drainage chamber 30 enter the drainage pipe 5 through the one-way drainage pipe 33, and are finally discharged through the drainage pipe 5. Therefore, during the period when the water pump 3 stops, some garbage and water in the water pumping port 2 can still be discharged, which not only increases the ability to clean garbage and impurities, but also enables the drainage to continue and ensure the drainage efficiency. After three minutes, the delay switch automatically closes, and the water pump 3 starts to pump water again, and the second reciprocating screw 36 stops rotating, and the auxiliary drainage stops.
