A dam is a water-retaining structure that intercepts the water flow of a river channel to raise the water level or regulate the flow. It can form a reservoir, raise the water level, adjust the runoff and concentrate the water head. It is used for flood control, water supply, irrigation, hydroelectric power generation and improvement of navigation. The river regime and the river regulation structures that protect the bank bed are also called dams, such as spur dams, shun dams, and submerged dams. However, when the dam releases water, the water flow will drive the garbage in the water through the dam, and these garbage will seriously affect the health of the environment.

Most of the existing filtering devices just install a layer of filter screen outside the dam.

Please refer to Figures 1-3, the utility model is a maintenance-free filter device for a water conservancy dam, which includes a precast dam water channel 1, and the two ends of the precast dam water channel 1 are respectively provided with a water inlet and a discharge port, and the drainage The height of the mouth is 20 centimeters higher than the height of the outlet, so that the water in the precast dam channel 1 flows to the outlet all the time.

The inner wall of the precast dam waterway 1 is provided with a first filter screen 9 for filtering water flow, so that the water in the precast dam waterway 1 passes through the first filter screen 9 when it flows.

One end of the first filter screen 9 near the water inlet is provided with a sliding plate 8 for scraping the first filter screen 9, and the sliding plate 8 slides and fits with the outer wall of the first filter screen 9 through a reciprocating transmission assembly. When the water in 1 contains impurities, the impurities are attached to the surface of the first filter screen 9 through the filtration of the first filter screen 9, and then the impurities attached to the surface of the first filter screen 9 are scraped off by the sliding of the sliding plate 8, so that The filtering effect of the first filter screen 9 returns to normal. When there are too many impurities on the surface of the first filter screen 9, the local pressure of the first filter screen 9 becomes larger, which easily deforms the first filter screen 9 and reduces the service life of the first filter screen 9. The partial pressure of the first filter screen 9 is released by scraping off the sliding plate 8 , which further improves the service life of the first filter screen 9 .

The reciprocating transmission assembly includes a threaded rod 5 and a connecting collar 7. A drive motor is installed on the upper end of the precast dam waterway 1. The output shaft of the drive motor is fixedly connected with the threaded rod 5. When the drive motor starts, the threaded rod is driven by the output shaft. 5 rotate synchronously.

The connecting collar 7 is mounted on the outer wall of the threaded rod 5 through internal and external threads, and the connecting collar 7 is fixedly connected to the end of the sliding plate 8 away from the first filter screen 9. When the threaded rod 5 rotates, the connecting collar 7 is matched with the internal and external threads. Rotate, while the connecting collar 7 is restricted by the sliding plate 8, so that the connecting collar 7 slides synchronously away from or close to the direction of the drive motor, and drives the sliding plate 8 to slide synchronously, so that the sliding plate 8 can clean the first filter screen 9 .

The upper end of the precast dam waterway 1 is fixedly connected with the installation plate 2, the top surface of the installation plate 2 is fixedly connected with the installation side plate 3, and the side wall of the installation side plate 3 is fixedly connected with the fixing plate 4, providing installation space for the drive motor.

The top surface of fixed plate 4 is fixedly connected with support plate 6, and one end of threaded rod 5 away from driving motor is rotatably connected on the outer wall of support plate 6, and when driving motor is started, the rotation of threaded rod 5 is difficult for offset position.

The mounting plate 2 and the fixed plate 4 are provided with a chute for sliding of the sliding plate 8, which provides restrictions for the fastening of the sliding plate 8, so that the sliding plate 8 is not easy to rotate synchronously with the connecting collar 7, and can only be moved along the mounting plate 2 and the fixed plate. 4 The chute that offers slides.

The side wall of the precast dam waterway 1 is equipped with a collection bin 11 for carrying impurities, and the inner cavity of the collection bin 11 is connected with the inner cavity of the precast dam waterway 1, so that the water flow in the precast dam waterway 1 can pass through The collection bin 11 flows to the drain.

The side wall of the collection bin 11 is equipped with a second filter screen 10 for blocking the flow of impurities in the inner cavity of the collection bin 11. When the water flow in the pre-cast dam channel 1 flows through the collection bin 11 to the drain, it passes through the second filter screen 10 The filtered water flows to the drain outlet, and the impurities in the water are filtered through the second filter screen 10 and stay in the collection bin 11, which is convenient for subsequent cleaning of impurities.

The side wall of the collection bin 11 is set in a slope shape, and the outer wall of the collection bin 11 slides and fits with the side wall of the second filter screen 10 close to the collection bin 11. When the impurities in the collection bin 11 need to be cleaned, the collection bin 11 is moved upwards. Lifting, the outer wall of the collection bin 11 scrapes off the surface of the second filter screen 10, so that the impurities attached to the surface of the second filter screen 10 are scraped off and fall into the collection bin 11, thereby improving the service life of the second filter screen 10.

The outer wall of the sliding plate 8 close to the first filter screen 9 is provided with a plurality of bristles for cleaning fine impurities, and the first filter screen 9 is scraped off by the bristles, so that the fine impurities attached to the surface of the first filter screen 9 are scraped off , to further improve the service life of the first filter screen 9.

The lower end of the collection bin 11 is provided with a baffle for blocking the water flow, and the outer wall of the baffle slides and fits with the side wall of the pre-cast dam waterway 1, so that when the collection bin 11 moves upward, the baffle rises synchronously to prevent the pre-casting Water in channel 1 of the dam overflows.

When the dam is opened to discharge water, water flows through the precast dam waterway 1, from the water inlet to the outlet, and then flows to the outlet after being filtered by the first filter screen 9. At the same time, the impurities blocked by the first filter screen 9 pass through The continuous washing of the water flow enters the collection chamber 11 along the surface of the first filter screen 9, and the water flowing through the inner cavity of the collection chamber 11 flows to the drain after being filtered by the second filter screen 10, and the impurities contained in the water pass through the second filter screen. The filter of the net 10 stays in the collection chamber 11. When the impurities retained on the surface of the first filter screen 9 are too much, the drive motor is started to drive the threaded rod 5 to rotate, so that the connecting collar 7 moves, and then passes through the mounting plate 2 and the fixing plate 4. For the limitation of the sliding plate 8, the connecting collar 7 is slid away from the direction of the driving motor. When the connecting collar 7 slides to a position close to the support plate 6, the driving motor is controlled to reverse, so that the connecting collar 7 is reset, thereby driving The sliding plate 8 slides back and forth to realize the repeated scraping of the first filter screen 9, so that the impurities attached to the surface of the first filter screen 9 flow into the collection bin 11. Compared with the filter screen in the prior art, the impurities in the water after long-term use Easy to block the filter screen, easy to operate, and prolong the service life of the device.
