Description

Technical Field

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

[0002] Currently, during flood control and drainage, a large number of sandbags are usually piled up to block floods, and then a water pump is used for pumping and draining water. Carrying sandbags consumes a lot of manpower and is very inconvenient. In addition, since there are a large number of solid impurities and garbage in the flood, these large-sized garbage and impurities enter the water pump and are easily stuck inside the water pump, causing damage to the water pump. Currently, a filter screen is usually set at the water intake to filter garbage and impurities. However, as the pumping progresses, a large amount of garbage and impurities will adhere to the surface of the filter screen, causing the filter screen to become blocked, resulting in a decreasing pumping efficiency. Most water intakes are usually set at low water levels, and it is impossible for workers to clean the filter screen in time. Therefore, when the filter screen is severely blocked for a long time, the water pump will be overloaded, causing the water pump to burn out.

[0003] Based on this, we propose a trailer-type flood control and drainage device. Summary of the Invention

[0010] Preferably, an auxiliary waterlogging drainage mechanism is installed on the carrier.

A sliding block is slidably connected to the inner wall of the auxiliary waterlogging drainage cavity.

[0014] Preferably, four installation grooves are formed in the lower end of the carrier. A universal wheel is slidably installed on the inner wall of each installation groove. A hydraulic cylinder is fixedly connected to the inner top of each installation groove. The movable end of the hydraulic cylinder is fixedly connected to the universal wheel.

[0015] The present invention has the following beneficial effects: 1. By setting up the cleaning mechanism, during the process of pumping water for drainage, the scraper reciprocates within the water intake, and can scrape off the impurities and garbage adhered to the filter screen, thereby avoiding an increasing amount of garbage and impurities adhered to the filter screen, which may cause serious blockage of the filter screen, further greatly reducing the pumping and drainage efficiency, and also avoiding damage to the water pump due to overload. It can continuously clean the filter screen during the drainage process without manual cleaning, which is more convenient; 2. By setting up the driving mechanism, when the scraper reciprocates, it will drive a plurality of bristles to move, cleaning the filter screen and improving the cleaning ability of the filter screen. And the gears will also move synchronously. Since one of the gears meshes with the rack, the gears will rotate synchronously, driving a plurality of rotating rods to rotate, so that the plurality of bristles can rotate while reciprocating horizontally, further improving the cleaning ability. And the rotation of the rotating rods will drive a plurality of crushing knives to rotate. The crushing knives will crush the impurities and garbage, making them smaller and reducing their adhesion ability on the surface of the filter screen. When the volume of the crushed impurities and garbage is smaller than the aperture of the mesh holes of the filter screen, they can pass through the filter screen and be discharged along with the water flow through the water suction pipe, the water pump, and the drainage pipe. Because when the volume of the garbage and impurities is small enough to pass through the mesh holes of the filter screen, they will not block the water pump, and thus will not damage the water pump anymore. Therefore, while cleaning the filter screen, the garbage and impurities can be processed and discharged, thereby avoiding the repeated adhesion of the garbage and impurities to the surface of the filter screen, causing continuous blockage, and further improving the drainage ability; 3. By setting a flow sensor, when there are relatively large impurity wastes or a large amount of impurity wastes pour into the water intake within a short period of time, at this time, the relatively large impurities and wastes need to be scraped repeatedly by the scraper to be completely broken. As a result, the filter screen will be quickly blocked within a short period of time, causing a significant decrease in the water flow rate in the water suction pipe. Or a large amount of impurities and wastes pour in within a short period of time, making it impossible to be quickly discharged within a short period of time, which will also cause the filter screen to be quickly blocked within a short period of time, resulting in a significant decrease in the water flow rate in the water suction pipe. When the above situation occurs, the flow sensor will monitor that the flow rate in the water suction pipe has significantly decreased and lasts for more than one minute, and then the flow sensor will transmit a signal to control the delay switch to disconnect through the PLC control circuit. The delay switch will automatically close after three minutes of disconnection. When the delay switch is disconnected, the water pump will power off and stop pumping water. Because the filter screen is severely blocked at this time and cannot be cleaned within a short period of time, stopping the water pump can prevent the water pump from being burned out due to long-term overload, protect the water pump, and during the period when the water pump stops, the scraper is still reciprocating, driving the crushing knife to rotate, cleaning and crushing the wastes and impurities, thus leaving time to process the wastes and impurities; 4. By setting an auxiliary drainage mechanism and a triggering mechanism, during the period when the water pump stops, at this time, the electromagnet is energized to generate a magnetic repulsive force, pushing the magnetic column into the card slot. Then, when the helical gear ring rotates, it can drive the second helical gear to rotate, drive the hollow rotating rod to rotate, and thus drive the second reciprocating lead screw to rotate, driving the slider to slide in the auxiliary drainage cavity. The slider will drive the slide plate to reciprocate and seal through the connecting rod. Then, part of the waste impurities and water in the water intake are pumped into the auxiliary drainage cavity through the one-way water inlet pipe. Then, the waste impurities and water in the auxiliary drainage cavity 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, part of the wastes and water in the water intake can still be discharged, which not only increases the cleaning ability of the waste impurities but also enables the drainage to continue without stopping, ensuring the drainage efficiency; 5. When the filter screen of the water pump is severely blocked, the water pump will automatically stop to prevent the water pump from being burned out due to overload. At this time, the auxiliary drainage will be started, and the servo motor is used to drive the slide plate to reciprocate and seal. At this time, the load of the servo motor will increase, but only for three minutes, which will not cause a great impact on the servo motor. Therefore, during the entire drainage process, the water pump and the servo motor will operate alternately for drainage, which can ensure that the drainage work is uninterrupted, improve the drainage efficiency, and 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.

Detailed implementation manners

[0018] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementations disclosed below.

[0019] Refer to Figures 1-9, a trailer-type flood control and drainage device, including a carrier 1, a water pumping port 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 communicated with the water pumping port 2 through a water pumping pipe 4, the water drainage port of the water pump 3 is fixedly connected with a drainage pipe 5, and a filter screen 6 is fixedly connected to the inner wall of the water pumping port 2; Further, when the water pump 3 is started, under the action of the water pump 3, water can enter the water pumping 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, impurities and garbage in the water will be intercepted by the filter screen 6, thereby preventing the impurities and garbage from entering the water pump 3 and blocking the water pump 3, so as to avoid damage to the water pump 3.

[0020] A cleaning mechanism, the cleaning mechanism includes a first sliding groove 7 opened on the inner wall of the water pumping port 2, a scraping plate 8 is slidably connected to the inner wall of the first sliding groove 7 (as Figure 9 shown), one end of the scraping plate 8 is arranged in contact with the surface of the filter screen 6, two storage tanks 9 are symmetrically opened on the inner wall of the water pumping port 2, two installation cavities 10 are symmetrically opened in the scraping plate 8, and a plurality of rotating rods 11 are rotatably connected to the inner walls of the two installation cavities 10. One end of some of the rotating rods 11 penetrates through the side wall of the scraping plate 8 and is fixedly connected with a circular plate 12 (the two rotating rods 11 at the bottom do not install the circular plate 12 and only play a role in transmitting torque), a plurality of bristles 13 are fixedly connected to the side wall of the circular plate 12, and all the plurality of bristles 13 are arranged in contact with the surface of the filter screen 6, and a plurality of crushing knives 14 are fixedly connected to the side walls of some of the rotating rods 11; A driving mechanism is installed in the first sliding groove 7.

[0021] The driving mechanism includes a first reciprocating lead screw 15 rotatably connected to the inner wall of the first sliding groove 7, the side wall of the first reciprocating lead screw 15 is threadedly connected with the scraping plate 8, a cavity 16 is opened in the carrier 1, a rotating shaft 17 is rotatably connected to the top of the cavity 16, a disc 18 is fixedly connected to the lower end of the rotating shaft 17, a bevel gear ring 19 is fixedly connected to the lower end of the disc 18, one end of the first reciprocating lead screw 15 extends into the cavity 16 and is fixedly connected with 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 penetrates through the upper end of the carrier 1 and is fixedly connected with the rotating shaft 17.

[0022] The driving mechanism further includes a second sliding groove 22 opened at the bottom of the inner part of the water pumping port 2, the side wall of the scraping plate 8 is slidably connected to the inner wall of the second sliding groove 22, a rack 23 is fixedly connected to the inner wall of the second sliding groove 22, a gear 24 is fixedly connected to the side wall of each of the plurality of rotating rods 11 located in the installation cavity 10, the gears 24 are meshed with each other, and one of the gears 24 is meshed with the rack 23.

[0023] Further, when the scraper 8 reciprocates, it will synchronously drive multiple circular plates 12 to move, and then drive multiple bristles 13 to move, so as to clean the filter screen 6, improving the cleaning ability of the filter screen 6. Moreover, the gear 24 will also move synchronously. Since one of the gears 24 meshes with the rack 23, the gear 24 will rotate synchronously, so that all other gears 24 will rotate, driving multiple rotating rods 11 to rotate, thereby driving the circular plates 12 to rotate self - rotatably, enabling the multiple bristles 13 to rotate self - rotatably while reciprocating translationally, further improving the cleaning ability. In addition, the rotation of the rotating rod 11 will drive multiple crushing knives 14 to rotate, and the crushing knives 14 will crush the impurities and garbage, making them broken into smaller pieces and reducing their adhesion ability on the surface of the filter screen 6. Due to the continuous operation of the water pump 3, even if the garbage and impurities are 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 adhere to the filter screen 6. However, due to the presence of the crushing knives 14, when the scraper 8 reciprocates to push the garbage and impurities, the crushing knives 14 will also synchronously crush them. When the volume of the crushed impurities and garbage is smaller than the aperture of the mesh holes of the filter screen 6, they can pass through the filter screen 6 and be discharged through the water suction pipe 4, the water pump 3 and the drainage pipe 5 along with the water flow. Because when the volume of the garbage and impurities is small enough to pass through the mesh holes of the filter screen 6, they cannot block the water pump 3, and thus will no longer damage the water pump 3. Therefore, while cleaning the filter screen 6, the garbage and impurities can be processed and discharged, thereby avoiding the repeated adhesion of the garbage and impurities to the surface of the filter screen 6, causing continuous blockage, and further improving the drainage ability.

[0024] On the side walls of the scraper 8 located in the first chute 7, two first baffles 25 are symmetrically and fixedly connected. The side walls of the two first baffles 25 are hermetically and slidably connected to the inner wall of the first chute 7. Two first transverse grooves 26 are symmetrically formed in the carrier 1, and the two first baffles 25 are respectively hermetically and slidably connected to the inner walls of the two first transverse grooves 26. On the side walls of the scraper 8 located in the second chute 22, two second baffles 27 are symmetrically and fixedly connected. The side walls of the two second baffles 27 are hermetically and slidably connected to the inner wall of the second chute 22. Two second transverse grooves 28 are symmetrically formed in the carrier 1, and the two second baffles 27 are respectively hermetically and slidably connected to the inner walls of the two second transverse grooves 28.

[0025] 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 avoiding the influence of garbage and impurities on the rotation of the first reciprocating lead screw 15 and the gear 24.

[0026] A flow sensor 29 is installed on the inner wall of the water suction pipe 4 (as Figure 4 shown), and the flow sensor 29, the water pump 3 and an external delay switch are connected through a PLC control circuit.

[0027] Further, when there are relatively large impurity wastes or a large amount of impurity wastes pour into the water intake 2 in a short period of time, the relatively large impurities and wastes need to be crushed completely by the scraper 8 through multiple reciprocations. As a result, the filter screen 6 will be quickly blocked in a short period of time, causing a significant decrease in the water flow rate in the water suction pipe 4. Or, when a large amount of impurities and wastes pour in within a short period of time and cannot be quickly discharged within a short period of time, it will also cause the filter screen 6 to be quickly blocked in a short period of time, resulting in a significant decrease in the water flow rate in the water suction pipe 4. When the above situation occurs, when the flow sensor 29 monitors that the flow rate in the water suction pipe 4 has decreased significantly and the duration exceeds one minute, the flow sensor 29 will transmit a signal to control the delay switch to disconnect through the PLC control circuit. The delay switch will automatically close after three minutes of disconnection. When the delay switch is disconnected, the water pump 3 will lose power and stop pumping water. Because the filter screen 6 is severely blocked at this time and cannot be cleaned up within a short period of time, stopping the water pump 3 can prevent the water pump 3 from being burned out due to long-term overload, protecting the water pump 3. And during the period when the water pump 3 stops, the scraper 8 is still reciprocating, driving the crushing knife 14 to rotate to clean and crush the wastes and impurities, thereby reserving time for treating the wastes and impurities.

[0028] An auxiliary drainage mechanism is installed on the carrier 1. The auxiliary drainage mechanism includes an auxiliary drainage cavity 30 opened in the carrier 1. A slide plate 31 is hermetically and slidably connected to the inner wall of the auxiliary drainage cavity 30. The auxiliary drainage cavity 30 is communicated with the water intake 2 through a one-way water inlet pipe 32. The one-way water inlet pipe 32 only allows the water and wastes in the water intake 2 to enter the auxiliary drainage cavity 30. The auxiliary drainage cavity 30 is communicated with the drainage pipe 5 through a one-way drainage pipe 33. The one-way drainage pipe 33 only allows the water and wastes in the auxiliary drainage cavity 30 to be discharged into the drainage pipe 5. A slider 34 is slidably connected to the inner wall of the auxiliary drainage cavity 30. Two connecting rods 35 are symmetrically and fixedly connected to the side wall of the slider 34. The other ends of the two connecting rods 35 are fixedly connected to the side wall of the slide plate 31.

[0029] The auxiliary drainage mechanism further includes a second reciprocating lead screw 36 rotatably connected to the inner wall of the auxiliary drainage cavity 30. The side wall of the second reciprocating lead screw 36 is threadedly connected to the slider 34. A hollow rotating rod 37 is rotatably connected to the inner wall of the cavity 16. One end of the second reciprocating lead screw 36 extends into the hollow rotating rod 37. A second helical gear 38 is fixedly connected to the side wall of the hollow rotating rod 37. The second helical gear 38 is meshed and connected with the helical gear ring 19.

[0030] A trigger mechanism is installed on the second reciprocating lead screw 36. The trigger mechanism includes two vertical grooves 39 symmetrically formed on the side wall of the second reciprocating lead screw 36. The inner walls of the two vertical grooves 39 are both slidably connected with magnetic posts 40. A plurality of card slots 41 cooperating with the magnetic posts 40 are formed in the inner wall of the hollow rotating rod 37. A spring 42 is fixedly connected between the inner wall of the vertical groove 39 and the magnetic post 40. An electromagnet 43 is fixedly connected to the inner wall of the vertical groove 39. The electromagnet 43, the flow sensor 29 and the delay switch are connected through a PLC control circuit.

[0031] Further, during the stop period of the water pump 3, at this time, the electromagnet 43 is energized to generate magnetic repulsion, which pushes the magnetic post 40 into the card slot 41. Then, when the helical gear ring 19 rotates, it can drive the second helical gear 38 to rotate, drive the hollow rotating rod 37 to rotate, thereby driving the second reciprocating lead screw 36 to rotate, driving the slider 34 to slide in the auxiliary drainage cavity 30. The slider 34 drives the slide plate 31 to reciprocate and seal through the connecting rod 35. Then, part of the garbage impurities and water in the water intake 2 are pumped into the auxiliary drainage cavity 30 through the one-way water inlet pipe 32. Then, the garbage impurities and water in the auxiliary drainage cavity 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 stop period of the water pump 3, part of the garbage and water in the water intake 2 can still be discharged, which not only increases the cleaning ability of garbage impurities, but also enables the drainage not to stop, ensuring the drainage efficiency.

[0032] It is worth mentioning that when the filter screen 6 is severely blocked, the water pump 3 will automatically stop to prevent the water pump 3 from being overloaded and burned out. At this time, the auxiliary drainage will be started, and the servo motor 21 is used to drive the slide plate 31 to reciprocate and seal. At this time, the load of the servo motor 21 will increase, but only for three minutes, which will not cause a great impact on the servo motor 21. Therefore, during the entire drainage process, the water pump 3 and the servo motor 21 will operate alternately for drainage, which can ensure that the drainage work is uninterrupted, improve the drainage efficiency, and 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.

[0033] Two pin shafts 44 are symmetrically and rotatably connected to the upper end of the carrier 1. The side walls of the two pin shafts 44 are both fixedly connected with water baffle plates 45. Two drive motors 46 are symmetrically and fixedly connected to the upper end of the carrier 1 through brackets. The output ends of the two drive motors 46 are respectively fixedly connected with the two pin shafts 44.

[0034] Four installation grooves 47 are formed in the lower end of the carrier 1. A universal wheel 48 is slidably installed on the inner wall of each installation groove 47. A hydraulic cylinder 49 is fixedly connected to the top of each installation groove 47. The movable end of the hydraulic cylinder 49 is fixedly connected with the universal wheel 48.

[0035] In the present invention, the carrier 1 can be moved to a specified position by the rotation of 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. Then, the driving motor 46 is driven to rotate, driving the pin shaft 44 to rotate, and further driving the two water baffle plates 45 to rotate, so that the two water baffle plates 45 are opened. Cooperating with the carrier 1, the water flow can be blocked, which is more convenient than using sandbags to block the water flow, saving time and effort.

[0036] Then, the water pump 3 can be started. Under the action of the water pump 3, water can enter the water suction pipe 4 through the water suction 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 waterlogged area. When the water flows through the water suction port 2, the impurities and garbage in the water will be intercepted by the filter screen 6, thus preventing the impurities and garbage from entering the water pump 3 and blocking the water pump 3, and avoiding damage to the water pump 3.

[0037] During the process of pumping and draining waterlogged areas, the servo motor 21 is started synchronously. The servo motor 21 drives the rotating shaft 17 to rotate, and then drives the disc 18 to rotate, driving the helical gear ring 19 to rotate, thus driving the first helical gear 20 to rotate, driving the first reciprocating lead screw 15 to rotate, driving the scraper 8 to reciprocate in the water suction port 2. Then, the scraper 8 can scrape off the impurities and garbage adhering to the filter screen 6 and push them into the storage tanks 9 on both sides, so as to prevent more and more garbage and impurities from adhering to the filter screen 6, causing serious blockage of the filter screen 6, and greatly reducing the efficiency of pumping and draining waterlogged areas. Also, when the filter screen 6 is seriously blocked, the water pump 3 will be overloaded and damaged. It can continuously clean the filter screen 6 during the drainage process without manual cleaning, which is more convenient.

[0038] In addition, when the scraper 8 reciprocates, it will synchronously drive multiple circular plates 12 to move, and then drive multiple bristles 13 to move, so as to clean the filter screen 6, improving the cleaning ability of the filter screen 6. Moreover, the gear 24 will also move synchronously. Since one of the gears 24 meshes with the rack 23, the gear 24 will rotate synchronously, so that the other gears 24 will all rotate, driving multiple rotating rods 11 to rotate, thereby driving the circular plates 12 to rotate self - sufficiently, making the multiple bristles 13 rotate self - sufficiently while reciprocating horizontally, further improving the cleaning ability. And the rotation of the rotating rod 11 will drive multiple crushing knives 14 to rotate. The crushing knives 14 will crush the impurities and garbage, making them more finely crushed and reducing their adhesion ability on the surface of the filter screen 6. Due to the continuous operation of the water pump 3, even if the garbage and impurities are pushed into the sewage storage tank 9, some impurities and garbage will still flow out of the sewage storage tank 9 with the water flow under the action of the water pump 3 and continue to adhere to the filter screen 6. However, due to the presence of the crushing knives 14, when the scraper 8 reciprocates to push the garbage and impurities, the crushing knives 14 will also crush them synchronously. When the volume of the crushed impurities and garbage is smaller than the pore diameter of the filter screen 6, they can pass through the filter screen 6 and be discharged through the water suction 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 pores of the filter screen 6, they will not block the water pump 3, and thus will not damage the water pump 3 anymore. Therefore, while cleaning the filter screen 6, the garbage and impurities can be processed and discharged, thereby preventing the garbage and impurities from repeatedly adhering to the surface of the filter screen 6 and causing continuous blockage, and further improving the drainage ability.

[0039] In addition, when there are relatively large impurity garbage or a large amount of impurity garbage surges into the water intake 2 in a short period of time, at this time, the relatively large impurities and garbage need to be reciprocated by the scraper 8 multiple times to be completely broken. As a result, the filter screen 6 will be quickly blocked in a short period of time, causing a significant decrease in the water flow rate in the water suction pipe 4. Or a large amount of impurities and garbage surge 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, resulting in a significant decrease in the water flow rate in the water suction pipe 4. When the above situation occurs, when the flow sensor 29 monitors that the flow rate in the water suction pipe 4 has significantly decreased and the duration exceeds one minute, the flow sensor 29 will transmit a signal to control the delay switch to disconnect through the PLC control circuit. The delay switch will automatically close after three minutes of disconnection. When the delay switch is disconnected, at this time, the water pump 3 will power off and stop pumping water. Because the filter screen 6 is severely blocked at this time and cannot be cleaned up in a short period of time, stopping the water pump 3 can prevent the water pump 3 from being burned out due to long-term overload, protecting the water pump 3. And during the period when the water pump 3 stops, the scraper 8 is still reciprocating, driving the crushing knife 14 to rotate, cleaning and crushing the garbage and impurities, so as to reserve time for processing the garbage and impurities. At this time, the electromagnet 43 will be energized to generate a magnetic repulsive force, pushing the magnetic column 40 into the card slot 41. Then, when the helical gear ring 19 rotates, it can drive the second helical gear 38 to rotate, driving the hollow rotating rod 37 to rotate, thereby driving the second reciprocating lead screw 36 to rotate, driving the slider 34 to slide in the auxiliary drainage cavity 30. The slider 34 will drive the slide plate 31 to reciprocate and seal through the connecting rod 35. Then, part of the garbage impurities and water in the water intake 2 are pumped into the auxiliary drainage cavity 30 through the one-way water inlet pipe 32. Then, the garbage impurities and water in the auxiliary drainage cavity 30 will enter the drainage pipe 5 through the one-way drainage pipe 33 and finally be discharged through the drainage pipe 5. Therefore, during the period when the water pump 3 stops, part of the garbage and water in the water intake 2 can still be discharged, not only increasing the cleaning ability of the garbage impurities, but also enabling the drainage to continue without stopping, ensuring the drainage efficiency. After three minutes, the delay switch automatically closes. At this time, the water pump 3 is started again to pump water, and the second reciprocating lead screw 36 will stop rotating, and the auxiliary drainage stops.
