Description

Technical Field

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

[0002] With the acceleration of urbanization, the hardened area of ​​urban ground is increasing, and the natural infiltration and evaporation capacity of rainwater has dropped significantly. During the rainy season, urban waterlogging occurs frequently, and a large amount of accumulated water seriously affects urban traffic, residents' lives and the normal operation of urban infrastructure. Traditional drainage pipe systems often have problems such as insufficient drainage capacity and easy blockage when dealing with extreme rainfall. For example, the drainage pipes in some old urban areas are small in diameter and old, with a lot of silt in the pipes, making it difficult to quickly and effectively drain a large amount of rainwater.

[0003] The patent with publication number CN220978261U relates to a drainage technology field, and in particular to a drainage device for water conservancy projects. Technical problem: When the device is used, the pipeline may be blocked by impurities, resulting in the inability to divert and drain water normally, and the filter plate filters out impurities such as silt in the water. If it cannot be quickly cleaned, the device will be blocked. Technical solution: A drainage device for water conservancy projects includes a drainage component; it also includes a first water diversion component and a second water diversion component. The device diverts water through the first water diversion component and the second water diversion component to solve the problem that when the device is used, the pipeline may be blocked by impurities, resulting in the inability to divert and drain water normally, and the filter plate filters out impurities such as silt in the water. If it cannot be quickly cleaned, the device will be blocked. However, when solving the problem of water flow blockage, the device simply scrapes off the impurities on the surface of the filter plate, and the treatment effect is relatively simple. When impurities such as branches and leaves flow through the drainage channel, the drainage channel is still prone to blockage. Therefore, a drainage device for water conservancy projects is proposed to solve the above-mentioned problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a drainage device for water conservancy projects in view of the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a drainage device for water conservancy projects, comprising a water inlet, a connecting pipe is fixedly connected to the bottom of the water inlet, a shell is fixedly connected to the bottom of the connecting pipe, and a water outlet is fixedly connected to the bottom of the shell; a crushing device is arranged on the inner wall of the water inlet, a dredging device is arranged on the inner wall of the connecting pipe, and a vibrating device is arranged on the circumferential surface of the shell; the crushing device comprises a fixed frame, a motor, a rotating shaft, a leaking plate, a fixed rod one, a crushing rod, a transmission wheel one, a fixed rod two, an arc plate, and a scraper, the fixed frame is fixedly connected to the inner wall of the water inlet, the motor is fixedly connected to the top of the fixed frame, the rotating shaft is fixedly connected to the output end of the motor, the fixed rod one is fixedly connected to the circumferential surface of the rotating shaft, the crushing rod is rotatably connected to the inner wall of the fixed rod one, the transmission wheel one is fixedly connected to the circumferential surface of the crushing rod, and the fixed rod two is fixedly connected to the rotating The circumferential surface of the shaft, the arc plate is fixedly connected to the side of the fixing rod 2 away from the rotating shaft, the scraper is fixedly connected to the bottom of the arc plate, the inner wall of the fixing frame is in contact with the circumferential surface of the rotating shaft, the circumferential surface of the driving wheel 1 is in contact with the circumferential surface of the water leakage plate, the surface of the scraper is in contact with the circumferential surface of the water leakage plate, the circumferential surface of the crushing rod is in contact with the circumferential surface of the water leakage plate, and the circumferential surface of the crushing rod is in contact with the circumferential surface of the fixing rod 2. When drainage is required, water will enter through the edge of the water inlet, so that friction is generated between the driving wheel 1 and the water leakage plate to rotate, so that impurities such as branches and leaves mixed in the water flow that are easy to cause blockage can be crushed, avoiding the blockage of the drainage device and affecting the circulation of water flow, and improving the drainage effect of the drainage device. At the same time, the rotation of the arc plate drives the scraper to rotate, so that the holes on the surface of the water leakage plate can be scraped open, avoiding the crushed impurities from accumulating at the bottom of the water inlet, causing the holes on the inner wall of the leakage plate to be blocked, affecting the flow effect of the water flow.

When draining and diverting water, the toggle plate is squeezed and swings, so that impurities attached to the inside of the connecting pipe can be dropped, avoiding excessive accumulation of impurities in the process of diverting water flow, resulting in blockage inside the connecting pipe, causing the flow rate of the water to slow down and the time for discharging water to increase. The upstream water continues to converge, and water accumulation will occur. At the same time, the rotation of the connecting plate drives the circular plate to rotate, so that the bottom filter plate can be cleaned, avoiding excessive accumulation of impurities on the surface of the filter plate, which in turn causes blockage of the holes inside the filter plate, making the flow effect of the water flow worse and affecting the drainage effect of the drainage device. When there are too many impurities on the surface of the filter plate, the movable door on the surface of the outer shell can be opened, and the internal impurities can be pushed out through the cleaning plate, so as to facilitate the cleaning of the device.

When dredging impurities, the second transmission wheel rotates to drive the stirring plate to rotate, so that the medicine flowing out of the medicine box can be stirred, so that the medicine can be fully mixed in the sewage water flow, so that the added medicine can degrade and purify the acidic substances in the water flow, and avoid the discharged sewage from flowing into the river and polluting the river. At the same time, the filter plate can be vibrated, so that the impurities in the holes inside the filter plate can be shaken off, and the fluidity of the water flow can be improved. The rotation of the rotating rod will contact the fixed column, thereby pushing the fixed column to rotate. The rotation of the fixed column drives the flow-limiting plate to rotate, and then the displacement of the medicine can be controlled to avoid the medicine flowing out too fast and causing waste of medicine.

The drainage device for water conservancy projects cooperates with the water inlet, connecting pipe, shell, water outlet, crushing device, fixed frame, motor, rotating shaft, leaking plate, fixed rod 1, crushing rod, transmission wheel 1, fixed rod 2, arc plate and scraper to operate. When drainage is required, water flows in through the edge of the water inlet, so that friction is generated between transmission wheel 1 and the leaking plate to cause rotation, so that impurities such as branches and leaves mixed in the water flow that are easy to cause blockage can be crushed to avoid clogging of the drainage device and affecting the circulation of water flow, thereby improving the drainage effect of the drainage device. At the same time, the rotation of the arc plate drives the scraper to rotate, so that the holes on the surface of the leaking plate can be scraped open to avoid the crushed impurities from accumulating at the bottom of the water inlet, causing the holes on the inner wall of the leaking plate to be blocked and affecting the flow effect of the water flow.

[0009] 2.

As the upstream water continues to converge, water accumulation will occur. At the same time, the connection plate 2 rotates to drive the circular plate to rotate, so as to clean the filter plate at the bottom, so as to avoid excessive accumulation of impurities on the surface of the filter plate, which in turn causes blockage of the holes inside the filter plate, deteriorates the flow effect of the water flow and affects the drainage effect of the drainage device. When there are too many impurities on the surface of the filter plate, the movable door on the outer shell surface can be opened, and the internal impurities can be pushed out through the cleaning plate, so as to facilitate the cleaning of the device.

At the same time, the filter plate can be vibrated to shake off the impurities in the holes inside the filter plate and improve the fluidity of the water flow. The rotation of the rotating rod will contact the fixed column, thereby pushing the fixed column to rotate. The rotation of the fixed column drives the flow-limiting plate to rotate, and then the discharge volume of the reagent can be controlled to prevent the reagent from flowing out too quickly and causing waste of the reagent.
