Description

Technical Field

[0001] The invention relates to the technical field of forebay filtration for a drainage pump station for irrigation, and in particular to forebay filtration equipment for a drainage pump station for irrigation. Background Art

[0002] A pump station is a device that can provide hydraulic power and pneumatic power with a certain pressure and flow. A pump station project is a general term for buildings such as the water inlet, water outlet, and pump room of a drainage and irrigation pump station. In a pump station project, the function of the pump station forepool is to connect the diversion channel and the water inlet pool. Its function is to reasonably connect the diversion channel and the water inlet pool so that the water flows smoothly and evenly into the water inlet pool, providing good water absorption conditions for the water pump.

[0003] The existing filtering device filters the irrigation water stored in the pool in front of the station through the filter. However, as the use time of the filter increases, the impurities accumulated on the filter also increase. At this time, it is necessary to stop the delivery of irrigation water, clean the filter and then resume the delivery of irrigation water. When there are many impurities in the water, it is necessary to frequently stop the delivery of irrigation water, which affects the normal progress of irrigation work. If the filter is not cleaned, the water volume in the filter will continue to increase, and the pressure on the filter will continue to increase. If things go on like this, the filter will be easily damaged, affecting the normal use of the filter. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a filtering device for a forebay of a drainage pump station for irrigation, comprising: A main body, one end of which is provided with a water inlet, the other end of which is provided with a water outlet, the inner side of the main body is rotatably connected to a rotating component, and one end of the water inlet is rotatably connected to a cleaning component; A clearing component, which filters the water entering the main body, is arranged near the water outlet, and the side of the clearing component is fixedly connected to the inner side of the main body; The blockage clearing component comprises a connecting block, a side of the connecting block is fixedly connected to the inner side of the main body, a side of the connecting block away from the inner wall of the main body is fixedly connected to a telescopic rod, a first spring is sleeved on the telescopic rod, one end of the first spring is fixedly connected to the connecting block, the other end of the first spring is fixedly connected to the slider, the other end of the telescopic rod is fixedly connected to a filter mechanism, and the side of the filter mechanism is slidably connected to the inner side of the main body; When the drainage pump is working, the water flow in the pool in front of the station is continuously pumped in through the drainage pump, and the filter mechanism is pumped by the drainage pump. The filter mechanism is impacted by the water flow, so that the filter mechanism squeezes the first spring and moves toward the connecting block at the same time, so that the filter mechanism filters the water flow entering the main body; Preferably, the filtering mechanism comprises a mesh plate, a slider is fixedly connected to the side surface of the mesh plate, a side of the slider close to the connecting block is fixedly connected to an end of the telescopic rod away from the connecting block, a side of the slider away from the mesh plate is slidably connected to the inner side of the main body, a side of the mesh plate close to the connecting block is slidably connected to a sliding rod, an end of the sliding rod away from the mesh plate is fixedly connected to a bracket, a second spring is sleeved on the sliding rod, one end of the second spring is fixedly connected to the bracket, and the other end of the second spring is fixedly connected to a side of the mesh plate close to the connecting block, a clearing rod is evenly arranged on the side of the bracket close to the mesh plate, the clearing rod is concentrically arranged with the mesh hole of the mesh plate, and one end of the clearing rod is fixedly connected to the bracket; Through the extraction work of the drainage pump, the mesh plate moves toward the connection block on the inner side of the main body through the slider. When the mesh plate filters the water flow entering the main body, the drainage pump continuously extracts the water flow in the pool in front of the station. Driven by the water flow, the bracket drives the clearing rod to move to the side away from the mesh plate. When the drainage pump is pumping water, when the extraction force of the drainage pump on the water flow is less than the tensile force of the second spring, the bracket is driven by the reset of the second spring, so that the bracket drives the clearing rod to move toward the mesh plate through the sliding rod, so that the bracket drives the clearing rod to move toward the mesh holes of the mesh plate, so that the clearing rod can push out the impurities blocked in the mesh plate, thereby preventing the mesh holes of the mesh plate from being blocked by impurities in the water flow when the mesh plate is filtering the water flow. At the same time, when the drainage pump finishes the extraction work of the water flow in the pool in front of the station, and the drainage pump stops working, the bracket can also be driven by the reset of the second spring, so that the bracket drives the clearing rod to clean the mesh holes of the mesh plate; Preferably, the rotating component comprises a rotating frame, both ends of the rotating frame are fixedly connected with spiral blades, a side of the spiral blade away from the rotating frame is rotatably connected to the side of the screen, and the side of the rotating frame is fixedly connected with a contact mechanism; When the drainage pump is extracting, the mesh plate moves toward the connecting block in the main body through the slider, so that the mesh plate drives the rotating frame through the spiral blades to move in the main body. At the same time, the drainage pump continuously extracts water, so that the water flow in the pool in front of the station continuously enters the main body. The water flow entering the main body impacts the spiral blades at both ends of the rotating frame, so that the spiral blades drive the rotating frame to rotate on the inner side of the main body, and at the same time, the rotating frame drives the contact mechanism to contact and rotate with the inner side of the main body, thereby cleaning the inner side of the main body. When the drainage pump stops working after extracting water from the pool in front of the station, the bracket can also be reset and moved in the main body through the reset drive of the second spring, so that the connecting frame drives the baffle to separate from the inner side of the main body, so that the impurities cleaned from the inner side of the main body can flow out of the main body; Preferably, the contact mechanism comprises a contact block, the number of the contact blocks is three, the three contact blocks are evenly arranged with the rotating frame as the center, a contact groove is opened on the side of the contact block away from the rotating frame, a contact rod is slidably connected to the inner side of the contact groove, an end of the contact rod away from the contact groove is fixedly connected to a contact plate, both sides of the contact plate are slidably connected to the inner side of the contact groove, a bent plate is fixedly connected to one side of the contact plate, a rubber plate is fixedly connected to the other side of the contact plate, a third spring is sleeved on the contact rod, one end of the third spring is fixedly connected to the contact plate, and the other end of the third spring is fixedly connected to the inner side of the contact groove; When the rotating frame rotates following the spiral leaves at both ends, the rotating frame drives the contact block to rotate, so that the contact block drives the bent plates on both sides of the contact plate and the rubber plate to contact and rotate with the inner side of the main body. By setting the bending angle of the rubber plate to be greater than the bending angle, the inner side of the main body can be better cleaned. At the same time, when the contact extrusion force between the bent plate and the rubber plate and the inner side of the main body is greater than the extrusion force of the third spring, the third spring is subjected to the extrusion force, so that the contact plate moves toward the contact groove through the contact rod, thereby avoiding the phenomenon that the bent plate causes scratches and damage to the inner side of the main body when cleaning the inner side of the main body. Preferably, the cleaning component comprises a baffle, which is arranged near the water inlet, the side of the baffle is slidably connected to the inner side of the main body, the inner side of the baffle is rotatably connected to one end of the spiral blade away from the rotating frame, and the side of the baffle away from the spiral blade is rotatably connected to the cleaning mechanism; When the drainage pump is extracting, the rotating frame follows the mesh plate and moves toward the connecting block in the main body through the slider, so that the rotating frame drives the baffle and the cleaning mechanism to move through the spiral blades on the other side, so that when the drainage pump extracts the water flow in the front pool, it can filter the water flow through the baffle, thereby preventing larger impurities in the front pool, such as leaves, from entering the main body. At the same time, when the rotating frame rotates, it drives the cleaning mechanism to rotate on the baffle; Preferably, the cleaning mechanism comprises a rotating rod, the side surface of the rotating rod is rotatably connected to the inner side of the baffle, the end of the rotating rod away from the round block is fixedly connected to the side of the spiral blade away from the rotating frame, one end of the rotating rod is fixedly connected to the round block, the side surface of the round block is fixedly connected to the tilting rod, the number of the tilting rods is three, the three tilting rods are evenly arranged with the baffle as the center, the side of the tilting rod close to the baffle is fixedly connected to the cleaning rod, the side of the cleaning rod away from the tilting rod is in contact with the side surface of the baffle, and the side surface of the cleaning rod is evenly provided with a clearance groove; When the rotating frame rotates following the spiral blades at both ends, the spiral blades drive the round block to rotate through the rotating rod, so that the round block drives the tilting rod to rotate on the baffle. By setting the tilting rod at an angle, the tilting rod sweeps off the leaves attached to the baffle, preventing the fallen leaves in the pool in front of the station from being driven by the water flow and attached to the baffle, thereby interfering with the water flow entering the main body. At the same time, a cleaning rod is arranged on the side of the tilting rod close to the baffle, so that when the tilting rod rotates, it can drive the cleaning rod to rotate on the baffle. At the same time, the cleaning rod is made of rubber material, and by evenly opening yield grooves on the side of the cleaning rod, the cleaning rod can penetrate into the gaps and corners to clean the surface of the baffle more carefully, thereby ensuring the cleanliness of the baffle.

[0005] The present invention provides a filtering device for a forebay of a drainage pump station for irrigation, which has the following beneficial effects: 1.

[0006] 2. This irrigation drainage pump station forebay filtration equipment is provided with a contact mechanism. The rotating frame drives the rubber plate to rotate. The bending angle of the rubber plate is greater than that of the bent plate, so it can fit more closely with the inner side of the main body, cover more areas, reduce cleaning dead corners, and more effectively scrape off dirt and impurities attached to the inner side of the main body, thereby improving the overall cleaning effect and ensuring the cleanliness of the inside of the main body.

[0007] 3. This irrigation drainage pump station forepool filtering equipment is provided with a tilting rod, which is tilted to form a specific angle with the baffle.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0012] See also Figure 1-Figure 3 The present invention provides a technical solution: a filtering device for a forebay of a drainage pump station for irrigation, comprising: A main body 1, a water inlet 2 is provided at one end of the main body 1, a water outlet 3 is provided at the other end of the main body 1, a rotating component 4 is rotatably connected to the inner side of the main body 1, and a cleaning component 6 is rotatably connected to one end of the water inlet 2; A clearing component 5, which filters the water entering the main body 1, is arranged close to the water outlet 3, and the side of the clearing component 5 is fixedly connected to the inner side of the main body 1; See also Figure 1-Figure 4The clearing component 5 includes a connecting block 51, a side of the connecting block 51 is fixedly connected to the inner side of the main body 1, a side of the connecting block 51 away from the inner wall of the main body 1 is fixedly connected to a telescopic rod 52, a first spring 53 is sleeved on the telescopic rod 52, one end of the first spring 53 is fixedly connected to the connecting block 51, the other end of the first spring 53 is fixedly connected to a slider 542, the other end of the telescopic rod 52 is fixedly connected to a filtering mechanism 54, and the side of the filtering mechanism 54 is slidably connected to the inner side of the main body 1; Specifically, when the drainage pump is working, the water flow in the pool in front of the station is continuously pumped in by the drainage pump, and the filter mechanism 54 is pumped by the drainage pump. The filter mechanism 54 is impacted by the water flow, so that the filter mechanism 54 squeezes the first spring 53 and moves toward the connecting block 51 at the same time, so that the filter mechanism 54 filters the water flow entering the main body 1; See also Figure 1-Figure 5 The filtering mechanism 54 includes a mesh plate 541, a slider 542 is fixedly connected to the side of the mesh plate 541, a side of the slider 542 close to the connecting block 51 is fixedly connected to an end of the telescopic rod 52 away from the connecting block 51, a side of the slider 542 away from the mesh plate 541 is slidably connected to the inner side of the main body 1, a side of the mesh plate 541 close to the connecting block 51 is slidably connected to a sliding rod 543, an end of the sliding rod 543 away from the mesh plate 541 is fixedly connected to a bracket 546, a second spring 544 is sleeved on the sliding rod 543, one end of the second spring 544 is fixedly connected to the bracket 546, and the other end of the second spring 544 is fixedly connected to a side of the mesh plate 541 close to the connecting block 51, and a clearing rod 545 is evenly arranged on the side of the bracket 546 close to the mesh plate 541, the clearing rod 545 is concentrically arranged with the mesh of the mesh plate 541, and one end of the clearing rod 545 is fixedly connected to the bracket 546; Specifically, through the extraction work of the drainage pump, the mesh plate 541 moves toward the connection block 51 in the inner side of the main body 1 through the slider 542. When the mesh plate 541 filters the water flow entering the main body 1, the drainage pump continuously extracts the water flow in the front pool of the station. Driven by the water flow, the bracket 546 drives the clearing rod 545 to move to the side away from the mesh plate 541. When the drainage pump is pumping water, when the extraction force of the drainage pump on the water flow is less than the tensile force of the second spring 544, the bracket 546 is driven by the reset of the second spring 544, so that the bracket 546 drives the clearing rod 545 to move toward the mesh plate 541 through the sliding rod 543, so that the bracket 546 drives the clearing rod 545 to move toward the mesh of the mesh plate 541, so that the clearing rod 545 can push out the impurities blocked in the mesh plate 541, thereby preventing the mesh of the mesh plate 541 from being blocked by impurities in the water flow when the mesh plate 541 is filtering the water flow. At the same time, when the drainage pump finishes the extraction work of the water flow in the front pool of the station, so that the drainage pump stops working, the bracket 546 can also be driven by the reset of the second spring 544, so that the bracket 546 drives the clearing rod 545 to clean the mesh of the mesh plate 541; This automatic clearing design can clear the mesh plate 541 in time when the drainage pump stops working, so that the entire drainage system can operate relatively stably under different working conditions, reduce system failures and abnormal operation caused by the blockage of the mesh plate 541, and improve the reliability and safety of the drainage system; See also Figure 1-Figure 7 , the present invention provides a technical solution: The rotating component 4 includes a rotating frame 41, both ends of the rotating frame 41 are fixedly connected with spiral blades 42, one side of the spiral blade 42 away from the rotating frame 41 is rotatably connected to the side of the mesh plate 541, and the side of the rotating frame 41 is fixedly connected with a contact mechanism 43; Specifically, when the drainage pump performs extraction work, the mesh plate 541 moves toward the connecting block 51 in the main body 1 through the slider 542, so that the mesh plate 541 drives the rotating frame 41 through the spiral blades 42 to move in the main body 1. At the same time, through the continuous extraction work of the drainage pump, the water flow in the front pool of the station continuously enters the main body 1, and the spiral blades 42 at both ends of the rotating frame 41 are impacted by the water flow entering the main body 1, so that the spiral blades 42 drive the rotating frame 41 to rotate on the inner side of the main body 1, and at the same time, the rotating frame 41 drives the contact mechanism 43 to contact and rotate with the inner side of the main body 1, thereby cleaning the inner side of the main body 1; When the drainage pump stops working after extracting water from the pool in front of the station, the bracket 546 can also be driven by the second spring 544 to reset and move in the main body 1, so that the connecting frame drives the baffle 61 to separate from the inner side of the main body 1, so that the impurities cleaned from the inner side of the main body 1 can flow out of the main body 1; See also Figure 1-Figure 8The contact mechanism 43 includes a contact block 431, the number of which is three, and the three contact blocks 431 are evenly arranged with the rotating frame 41 as the center. A contact groove 432 is provided on the side of the contact block 431 away from the rotating frame 41, and a contact rod 433 is slidably connected to the inner side of the contact groove 432, and a contact plate 435 is fixedly connected to one end of the contact rod 433 away from the contact groove 432, and both sides of the contact plate 435 are slidably connected to the inner side of the contact groove 432, a bent plate 436 is fixedly connected to one side of the contact plate 435, and a rubber plate 437 is fixedly connected to the other side of the contact plate 435, and a third spring 434 is sleeved on the contact rod 433, one end of the third spring 434 is fixedly connected to the contact plate 435, and the other end of the third spring 434 is fixedly connected to the inner side of the contact groove 432; Specifically, when the rotating frame 41 rotates following the spiral leaves 42 at both ends, the rotating frame 41 drives the contact block 431 to rotate, so that the contact block 431 drives the bent plates 436 and the rubber plates 437 on both sides of the contact plate 435 to contact and rotate with the inner side of the main body 1. By setting the bending angle of the rubber plate 437 to be greater than the bent plate 436, the inner side of the main body 1 can be better cleaned. At the same time, when the contact extrusion force between the bent plate 436 and the rubber plate 437 and the inner side of the main body 1 is greater than the extrusion force of the third spring 434, the third spring 434 is subjected to the extrusion force, so that the contact plate 435 moves toward the contact groove 432 through the contact rod 433, thereby avoiding the phenomenon that the bent plate 436 causes scratches and damages to the inner side of the main body 1 when cleaning the inner side of the main body 1. The larger bending angle enables the rubber plate 437 to contact the inner side of the main body 1 more fully when rotating, generating greater pressure and friction, and can more effectively scrape off stubborn stains, scale, etc., achieving deep cleaning, and ensuring that the inside of the main body 1 remains in a good clean state for a long time; See also Figure 1-Figure 9 The present invention provides a technical solution: the cleaning component 6 includes a baffle 61, which is arranged near the water inlet 2, the side of the baffle 61 is slidably connected to the inner side of the main body 1, the inner side of the baffle 61 is rotatably connected to the end of the spiral blade 42 away from the rotating frame 41, and the side of the baffle 61 away from the spiral blade 42 is rotatably connected to the cleaning mechanism 62; Specifically, when the drainage pump performs extraction work, the rotating frame 41 follows the mesh plate 541, and when the slider 542 moves toward the connecting block 51 in the main body 1, the rotating frame 41 drives the baffle 61 and the cleaning mechanism 62 to move through the spiral blade 42 on the other side, so that when the drainage pump performs extraction work on the water flow in the front pool, the water flow can be filtered through the baffle 61, thereby preventing larger impurities in the front pool, such as leaves, from entering the main body 1. At the same time, when the rotating frame 41 rotates, it drives the cleaning mechanism 62 to rotate on the baffle 61; See also Figure 1-Figure 10 The cleaning mechanism 62 includes a rotating rod 621, the side of the rotating rod 621 is rotatably connected to the inner side of the baffle 61, the end of the rotating rod 621 away from the round block 622 is fixedly connected to the side of the spiral blade 42 away from the rotating frame 41, one end of the rotating rod 621 is fixedly connected to the round block 622, the side of the round block 622 is fixedly connected to the inclined rod 623, the number of the inclined rods 623 is three, the three inclined rods 623 are evenly arranged with the baffle 61 as the center, the side of the inclined rod 623 close to the baffle 61 is fixedly connected to the cleaning rod 624, the side of the cleaning rod 624 away from the inclined rod 623 is in contact with the side of the baffle 61, and the side of the cleaning rod 624 is evenly provided with a clearance groove 625; Specifically, when the rotating frame 41 rotates following the spiral blades 42 at both ends, the spiral blades 42 drive the round block 622 to rotate through the rotating rod 621, so that the round block 622 drives the tilting rod 623 to rotate on the baffle 61. By tilting the tilting rod 623, the tilting rod 623 sweeps off the leaves attached to the baffle 61, thereby preventing the fallen leaves in the pool in front of the station from being driven by the water flow and attached to the baffle 61, thereby interfering with the water flow entering the main body 1. At the same time, a cleaning rod 624 is arranged on one side of the tilting rod 623 close to the baffle 61, so that when the tilting rod 623 rotates, it can drive the cleaning rod 624 to rotate on the baffle 61. At the same time, the cleaning rod 624 is made of rubber material. By evenly opening the side of the cleaning rod 624 with a clearance groove 625, the cleaning rod 624 can penetrate into the gap and corner, and clean the surface of the baffle 61 more carefully, thereby ensuring the cleanliness of the baffle 61. Specific workflow: Connect the water outlet 3 of the main body 1 to the input end of the drainage pump. After the water flows from the diversion channel into the fore pool, it flows to the mesh filter. The water with impurities enters the filter through the water inlet 2 of the filter. When the drainage pump is working, the water flow in the pool in front of the station is pumped into the drainage pump, so that the clearing component 5 moves inside the main body 1, so that the rotating component 4 and the cleaning component 6 enter the main body 1; The water flows into the main body 1, and the cleaning component 6 intercepts the impurities in the water flow. The water passes through the pores of the cleaning component 6 and enters the inner side of the main body 1 to complete the preliminary filtration. The water filtered by the cleaning component 6 enters the interior of the main body 1 through the water inlet 2, so that the cleaning component 5 performs a secondary filtering work on the water flow; As filtering proceeds, the water flows into the drain pump.
