Background technique

Rainwater collection refers to the process of collecting rainwater, treating it, and reusing it after obtaining water that meets certain water quality indicators. Specifically, rainwater collection can utilize the rainfall runoff collected from building roofs and hardened surfaces such as roads and squares.

When the device of the utility model is in use, the filter shell 2, the filter screen plate 15, the storage shell 26 and the vibration mechanism are arranged to provide a means for filtering and separating large particles of impurities during the rainwater collection process; the filter screen plate 15 is arranged obliquely from left to right, so that the large particles of impurities filtered by the filter screen plate 15 can naturally slide down the slope; at the same time, through the arrangement of the storage shell 26, the large particles of impurities sliding down from the filter screen plate 15 can be collected after passing through the connecting port 14; further, through the arrangement of the vibration mechanism, the large particles of impurities on the filter screen plate 15 can be more effectively vibrated into the storage shell 26 for collection, thereby solving the problem that the existing green building filtering equipment is blocked by large particles of impurities during filtering.

In the present embodiment, the lower end of the storage shell 26 is also provided with an openable opening, so that the staff can regularly open the storage shell 26 to clean up the impurities, and the storage shell 26 can be made of stainless steel. In the present embodiment, the filter screen plate 15 can be made of plastic material to better achieve vibration.

This device avoids the situation that when there are too many impurities in the filter screen 15 of the equipment, the filtering effect of the equipment will be reduced, and the cleaning of the equipment by the operator is reduced, which reduces the workload of the operator. At the same time, it also avoids the blockage of the equipment, reduces the repeated cleaning by the personnel, and increases the use effect of the equipment. The filtering effect of the equipment on rainwater is guaranteed, and the filtered impurities are cleaned, so that the equipment can work repeatedly.

As shown in Figure 2, in another embodiment, the vibration mechanism includes a connecting plate 6, a spring 5, a sliding rod 13, a first motor 8 and an arc block 12. A first cavity 3 is provided in the right side wall of the filter housing 2, and the bottom end of the first cavity 3 is fixedly connected to the spring 5, the upper end of the spring 5 is connected to the connecting plate 6, and the upper end of the connecting plate 6 is connected to the sliding rod 13.

As shown in FIG. 3 , in one embodiment, one end of the arc block 12 is a light end and the other end is a heavy end. The light end is fixedly connected to the end of the rotating rod 11, and the heavy end provides centrifugal force when rotating. When in use, the rotating rod 11 is driven to rotate by the first motor 8, and the rotating rod 11 drives the arc blocks 12 at the front and rear ends to rotate. When rotating, the heavy end of the arc block 12, due to its large mass, can generate enough centrifugal force to drive the rotating rod 11 to move, and under the constraint of the sliding connection between the sliding rod 13 and the upper end wall of the first cavity 3, the connecting plate 6 is moved up and down, thereby driving the filter screen plate 15 to vibrate. At the same time, the filter screen plate 15 can be made of plastic material to avoid rigid impact, and can also further increase the amplitude of vibration through deformation during movement.

Among them, in another embodiment, the spring 5 is used to provide an upward force, and the minimum distance between the rotating rod 11 and the top of the first cavity 3 is smaller than the distance between the rotating rod 11 and the end of the arc block 12. The arc block 12 is used to contact the top of the first cavity 3 when rotating and give the connecting plate 6 a downward force. When in use, the spring 5 is used to provide an upward force to keep the connecting plate 6 moving upward. The rotating rod 11 is driven to rotate by the first motor 8, and the arc blocks 12 at the front and rear ends are driven by the rotating rod 11 to rotate. When rotating, when the rotating end of the arc block 12 contacts the top of the first cavity 3, the connecting plate 6 is squeezed to move downward, and the spring 5 is compressed. Thereafter, the spring 5 rebounds until the rotating end of the arc block 12 contacts the top of the first cavity 3 again, and this cycle is repeated to achieve vibration. The filter screen 15 can also be made of plastic material.

Among them, a group of springs 5 are fixed on the front and rear sides of the bottom of the first cavity 3, each group includes two springs 5 located on the left and right sides, and an elastic damping column 4 is arranged in the middle of each spring, the lower end of the elastic damping column 4 is arranged at the bottom of the first cavity 3, and the upper end is connected to the connecting plate 6; the front and rear sides of the upper end of the connecting plate 6 are respectively connected to two sliding rods 13 distributed on the left and right, and the upper ends of the sliding rods 13 pass through the first cavity 3 to the connecting port 14, and are connected to the lower end surface of the right end of the filter screen plate 15. In this way, by setting the elastic damping column 4, the support strength of the connecting plate 6 can be increased without affecting the vibration; the setting of the two groups of springs 5 and the sliding rod 13 can increase the stability of the movement of the device.

As shown in Figure 4, in another embodiment, a cleaning structure is also included, which is arranged above the filter screen plate 15. The cleaning structure includes a second motor 17, a threaded rod 18, a movable plate 19, a cleaning plate 20 and a slider 22. On the front and rear side walls of the inner cavity of the filter shell 2, symmetrical slide grooves 21 inclined downward from left to right are opened. An inclined cavity 16 is opened in the left side wall of the filter shell 2, and a second motor 17 is arranged in the inclined cavity 16. The output shaft of the second motor 17 is connected to the left end of the threaded rod 18, and the right end of the threaded rod 18 is rotatably arranged in the right side wall of the filter shell 2. The threaded rod 18 is parallel to the slide groove 21, and the threaded rod 18 is connected to the center thread of the movable plate 19. The lower end of the movable plate 19 is fixedly connected with a cleaning plate 20, and the cleaning plate 20 is used to push impurities on the filter screen plate 15. A slider 22 is fixed to the front and rear ends of the movable plate 19, respectively, and the slider 22 is slidably arranged in the slide grooves 21 on the front and rear sides.

As shown in Figure 5, when in use, the threaded rod 18 is driven to rotate by the second motor 17, thereby driving the movable plate 19 threadably connected to the threaded rod 18 to move left and right under the constraints of the slider 22 and the slide groove 21. At the same time, during the movement, the impurities on the filter screen plate 15 are pushed to the connecting port 14 by the cleaning plate 20 and fall into the storage shell 26.

Wherein, bristles are arranged below the cleaning plate 20, and the bristles are in contact with the upper end surface of the filter screen plate 15. In this way, the cleaning of the filter screen plate 15 can be ensured to be complete by the bristles, and the rigid contact between the devices can be reduced.

In another embodiment, an arc plate 24 with an opening flared upward is fixed below the edge of the roof 23, and a water outlet 25 is provided at the arc plate 24 above the filter housing 2. In this way, rainwater can be collected and drained into the filter housing 2. In this embodiment, the roof 23 can be set to be sloped to help drain rainwater.

In another embodiment, the lower end of the filter housing 2 is provided with a water outlet pipe 27 connected to the inner cavity to increase the means of using the collected water. A valve switch is provided on the water outlet pipe 27 to increase the convenience of use.

When the device is in use, the second motor 17 in the inclined cavity 16 can be started to drive the threaded rod 18 at the output end to rotate, and the threaded rod 18 is rotated to drive the moving plate 19 and the slider 22 to move, and the cleaning plate 20 is also driven to move, so that the impurities on the filter screen plate 15 are cleaned to the connection port 14;

At this time, the first motor 8 in the second cavity 7 is started again to drive the first bevel gear 9 at the output end to rotate, and the second bevel gear 10 and the rotating rod 11 are driven to rotate by rotating the first bevel gear 9, and the two arc blocks 12 are also driven to rotate. The rotation of the arc block 12 causes the elastic damping column 4 and the spring 5 to move up and down, and the sliding rod 13 drives the filter screen plate 15 to move up and down, so that the impurities at the connecting port 14 will fall into the storage shell 26 through vibration, and the whole working process is released through the above-mentioned reverse operation.

Alternatively, the rotation frequency of the rotating rod 11 is set, and the vibration mechanism is set to daily vibration, and large particles of impurities are collected through the effects of vibration and free sliding to ensure the long-term use of the device; then the cleaning structure is driven regularly to stably clean the flocs or other impurities on the filter screen plate 15 to ensure the filtering effect of the device.
