Description

Technical Field

[0001] The invention relates to the technical field of emergency drainage, and in particular to an anti-clogging flood emergency drainage device. Background Art

[0002] Emergency drainage is a drainage measure taken quickly in an emergency to prevent waterlogging from causing damage to people, property and important facilities. It is commonly seen in urban waterlogging, building waterlogging, industrial flooding and emergency situations in water conservancy projects. Commonly used equipment includes mobile drainage pumps, submersible pumps, emergency drainage vehicles, integrated high-power drainage pumps, generator sets, control systems and pumping pipes. The existing emergency drainage measures are taken after the accumulation of water occurs, which cannot cope with sudden rainstorms. After the installation of the emergency drainage device, certain economic losses have already occurred. Therefore, it is necessary to design an emergency drainage device that can cope with sudden rainstorms. At the same time, during heavy rains, the water body is usually mixed with various impurities, such as branches, leaves, stones and various garbage, which can easily cause blockage. Therefore, we proposed an anti-blockage flood emergency drainage device. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an anti-clogging flood emergency drainage device, comprising: A box body, wherein a drain pipe is arranged at the bottom of the box body, the surface of the drain pipe is fixedly connected to the inner side surface of the box body, the drain pipe is used to connect to the drainage system, and a cover plate is fixedly connected to the top of the box body; A drainage mechanism, which is arranged inside the box and is fixedly connected to the inner side of the box; Wherein, the drainage mechanism comprises: A partition, which is arranged inside the box body and fixedly connected to the inner side surface of the box body, and the partition divides the inner cavity of the box body into two parts; The surface of the partition is symmetrically provided with connecting grooves, and the connecting grooves are provided on the surface slightly above the partition; A coarse screen assembly, the coarse screen assembly having a filtering structure for preliminarily screening out impurities in rainwater, and the surface of the coarse screen assembly is fixedly connected to the inner side of the cover plate; A crushing assembly having a counterweight structure for changing the crushing range, the crushing assembly being fixedly connected to the inner side of the box body, and the crushing assembly being arranged on a side of the partition away from the coarse screen assembly; The box is buried underground, and the end of the drainage pipe away from the box is connected to the urban drainage system. When it rains, rainwater passes through the coarse screen component and then enters the inside of the box, and then passes through the connecting groove and enters the part of the cavity of the box where the crushing component is provided, and finally enters the drainage system through the drainage pipe. The coarse screen component can screen out large impurities to prevent large and hard impurities such as stones and branches from entering the box, and to prevent large and hard impurities from causing damage to the crushing component. By setting a partition with a connecting groove, during heavy rain, rainwater carrying impurities first enters the side of the partition away from the crushing component, and then stones and other relatively solid and heavy impurities will settle inside the box, and soft floating impurities will pass through the connecting groove together with rainwater. Then start the crushing component, which crushes floating impurities such as leaves, small branches, and garbage, and finally enters the drainage system through the drain pipe, which can prevent impurities from being washed into the device and causing blockage during heavy rain. The partition is set to separate the inner cavity of the box, which can prevent heavy rain from washing some relatively solid impurities into the drainage system during heavy rain, avoiding blockage of the drainage system and ensuring that the drainage system will not collapse during emergency drainage. The setting of the crushing component can crush floating impurities to avoid accumulation of floating impurities and blockage. The partition treats solid impurities and floating impurities separately, which can prevent solid impurities from getting stuck and gradually producing disordered accumulation, and prevent suspended impurities from adhering to the surface of solid impurities, thereby avoiding gradual blockage by impurities.

[0008] Furthermore, the middle part of the filter bucket bulges toward the side close to the cover plate, and holes are distributed on the surface of the filter bucket, and the filter bucket has a plurality of holes evenly distributed. Impurities with larger mass will preferentially settle to the top of the filter bucket, and eventually pass through the holes on the filter bucket and enter the other side of the filter bucket. The bulge in the middle part of the filter bucket can keep the precipitated impurities away from the stirring column, thereby preventing the impurities from contacting the stirring column and causing it to get stuck.

A groove is provided on the surface of the stirring blade located inside the drain pipe. The stirring column rotates, driving the stirring blade to rotate, thereby stirring the bottom of the filter bucket, so that the water flow continuously impacts the holes of the filter bucket to prevent the filter bucket from being blocked. At the same time, the stirring blade is also located inside the drain pipe. When rotating, it can stir the inside of the drain pipe to prevent sediment from pouring into the drain pipe at one time, thereby preventing the drain pipe from being blocked. By providing the groove, the sediment can pass through the groove to prevent all sediment from being squeezed out of the drain pipe by the stirring blade.

The side is rotatably connected with a crushing leaf through a rotating rod, and the crushing leaf is bent, and the side of the crushing leaf close to the stirring column is slidably connected with a connecting arm, and the end of the connecting arm away from the crushing leaf is rotatably connected with a slide seat through a rotating rod, and the inner side surface of the slide seat is slidably connected with the surface of the slide column, and The surface of the slide seat is slidably connected to the inner side of the slide groove. When there is no heavy rain, the stirring column is not driven to rotate, and the crushing leaves naturally hang down to avoid impurities entering this part of the box being blocked by the crushing leaves. When it rains heavily, the stirring column is driven to rotate, and the stirring column drives the fixed seat to rotate, and the fixed seat drives the crushing leaves to rotate. The stirring column drives the slide seat to rotate, drives the connecting arm to rotate, and finally drives the crushing leaves to rotate, and at the same time drives the two sides of the crushing leaves to rotate, which can avoid the crushing leaves from bending or even breaking. As the stirring column rotates, under the action of centrifugal force, the crushing leaves rotate around the fixed seat and pull the connecting arm. While the connecting arm slides inside the crushing leaves, the other end pulls the slide seat up, increasing the rotation range of the crushing leaves, thereby better crushing the impurities. Multiple groups of crushing leaves can stir the impurities within the entire box to avoid the sinking of completely crushed impurities.

[0011] Furthermore, an arc groove is provided on the side of the crushing blade close to the stirring column, and a bent rod is provided inside the arc groove, and both ends of the bent rod are fixedly connected to the inner wall of the arc groove, the inner side surface of the connecting arm is slidably connected to the surface of the bent rod, and the surface of the connecting arm is slidably connected to the inner side surface of the arc groove, and a spring is sleeved on the outside of the bent rod, and the spring is fixedly connected to the surface of the bent rod, and one end of the spring close to the stirring column is fixedly connected to the surface of the connecting arm, and the connecting arm slides inside the arc groove, driving the spring to compress, thereby playing a buffering role.

Soft floating impurities pass through the connecting groove together with rainwater to separate the inner cavity of the box. During heavy rain, it can prevent heavy rain from washing some relatively solid impurities into the drainage system, avoid clogging the drainage system, and ensure that the drainage system will not collapse during emergency drainage. At the same time, the partition handles solid impurities and floating impurities separately, which can prevent solid impurities from getting stuck and gradually generating disordered accumulation, and prevent suspended impurities from adhering to the surface of solid impurities, thereby preventing impurities from gradually clogging.

[0014] The present invention provides a coarse screen component, and the coarse screen holes on the coarse screen plate perform primary screening of rainwater to prevent impurities such as longer branches from being washed into the interior of the box during heavy rain. When the funnel is blocked, the funnel is deformed by the pressure of rainwater, thereby automatically dredging. At the same time, during heavy rain, the rainwater flow rate increases, which compresses the inner side of the funnel, causing the funnel to deform, thereby expanding the funnel and obtaining a better drainage effect. The thickness of the funnel gradually increases toward the side close to the box, making the tail of the funnel more massive and easier to deform, thereby better completing the dredging after blockage and increasing the drainage volume during heavy rain.

[0015] The present invention provides a stirring blade, which rotates to stir the bottom of the filter bucket, so that the water flow continuously impacts the holes of the filter bucket to prevent the filter bucket from being blocked.

When there is heavy rain, the stirring column is driven to rotate, and the stirring column drives the fixed seat to rotate, and the fixed seat drives the crushing blades to rotate. The stirring column drives the sliding seat to rotate, drives the connecting arm to rotate, and finally drives the crushing blades to rotate. At the same time, the two sides of the crushing blades are driven to rotate, which can prevent the crushing blades from bending or even breaking. Under the action of centrifugal force, the crushing blades rotate around the fixed seat to increase the rotation range of the crushing blades, thereby better crushing the impurities. Multiple groups of crushing blades can stir the impurities within the entire box to prevent completely crushed impurities from sinking to the bottom.

The crushing assembly 44 is fixedly connected to the inner side of the box body 1, and the crushing assembly 44 is arranged on a side of the partition plate 41 away from the coarse screen assembly 43; The box body 1 is buried underground, and the end of the drainage pipe 2 away from the box body 1 is connected to the urban drainage system. When it rains, rainwater passes through the coarse screen component 43, then enters the inside of the box body 1, and then passes through the connecting groove 42 to enter the part of the cavity of the box body 1 provided with the crushing component 44, and finally enters the drainage system through the drainage pipe 2. The coarse screen component 43 can screen out large-volume impurities, and prevent large-volume hard impurities such as stones and branches from entering the inside of the box 1, and prevent the hard large-volume impurities from causing damage to the crushing component 44. By providing a partition 41 with a connecting groove 42, during heavy rain, rainwater carrying impurities first enters the side of the partition 41 away from the crushing component 44, and then stones and other relatively solid and heavy impurities will settle inside the box 1, and soft floating impurities will pass through together with the rainwater.

At the same time, the stirring blade 444 is also located inside the drain pipe 2. When it rotates, it can stir the inside of the drain pipe 2 to prevent the sediment from rushing into the drain pipe 2 at one time, thereby preventing the drain pipe 2 from being blocked. By opening the groove body 445, the sediment can pass through the groove body 445 to prevent all the sediment from being squeezed out of the drain pipe 2 by the stirring blade 444. As the rainwater continues to pass, part of the sediment is continuously brought into the drain pipe 2 to achieve the purpose of preventing blockage.

The side of the shell 4425 close to the driving shaft 4424 is fixedly connected to the side of the shell 4421 away from the cover plate 3. Start the motor 4426, and the output end of the motor 4426 drives the driving shaft 4424 to rotate, and the driving shaft 4424 drives the conveyor belt 4423 to transmit, thereby driving the stirring column 441 to rotate, and the shell 4421 and the shell 4425 are set to protect the motor 4426.

[0031] The box body 1 is buried underground, and the end of the drainage pipe 2 away from the box body 1 is connected to the urban drainage system. When there is no heavy rain, the stirring column 441 is not driven to rotate, and the crushing blades 449 hang down naturally, and the rainwater passes through the funnel 433, and the funnel 433 further blocks the impurities. When the funnel 433 is blocked, the funnel 433 is deformed by the pressure of the rainwater, so that it is automatically dredged, and then the rainwater enters the box body 1. The relatively solid and heavy impurities such as stones will settle inside the box 1, and the soft floating impurities will pass through the connecting groove 42 together with the rainwater, and enter the part of the cavity of the box body 1 where the crushing assembly 44 is provided, and finally enter the drainage system through the drainage pipe 2. When heavy rain occurs, the motor 4426 is started, and the output end of the motor 4426 drives the driving shaft 4424 to rotate, and the driving shaft 4424 drives the conveyor belt 4423 to transmit, thereby driving the stirring column 441 to rotate, and the stirring column 441 drives the fixing seat 447 to rotate, and the fixing seat 447 drives the crushing blades 449 to rotate, and the stirring The mixing column 441 drives the slide 4411 to rotate, drives the connecting arm 4410 to rotate, and finally drives the crushing blade 449 to rotate. As the stirring column 441 rotates, under the action of centrifugal force, the crushing blade 449 rotates around the fixed seat 447 and pulls the connecting arm 4410. While the connecting arm 4410 slides inside the crushing blade 449, the other end pulls the slide 4411 to increase the rotation range of the crushing blade 449, and the crushing blade 449 crushes the floating impurities. The impurities with larger mass will first settle to the top of the filter bucket 443, and finally pass through the holes on the filter bucket 443 and enter the other side of the filter bucket 443. At the same time, the stirring column 441 rotates, driving the stirring blade 444 to rotate, thereby stirring the bottom of the filter bucket 443, so that the water flow continuously impacts the holes of the filter bucket 443, stirring the inside of the drain pipe 2, and preventing the sediment from pouring into the drain pipe 2 at one time. As the rainwater continues to pass, part of the sediment is continuously brought into the drain pipe 2, and finally the emergency drainage is completed.
