Description

Technical Field

[0001] The utility model relates to the technical field of municipal water supply and drainage, in particular to a filtering device for municipal water supply and drainage. Background Art

[0002] When draining water in the city, especially during total drainage, due to the large amount of water and the requirement of service life, an underground drainage culvert will be built under the ground. The underground drainage culvert is made of multiple cylindrical cement wells. During actual drainage, although the sewage discharged into the underground drainage culvert has been filtered, the filtration cannot completely filter out all the floating garbage in the sewage. There will still be floating garbage in the sewage in the underground drainage culvert. Since the underground drainage culvert is long and there are many sewage outlets entering the underground drainage culvert, and there is no filtering device for floating garbage in the underground drainage culvert, this causes the floating garbage in the underground drainage culvert to be scattered everywhere. In order to prevent the floating garbage from causing poor drainage or blockage of the underground drainage culvert, there will be staff to clean it regularly. Since the floating garbage is scattered over a large area, it is time-consuming and laborious. Therefore, a filtering device for municipal water supply and drainage is needed to meet the requirements. Content of the Utility Model

[0003] The purpose of the utility model is to solve the disadvantages of large scattered area and difficult cleaning of floating garbage in the existing underground drainage culvert, and to propose a filtering device for municipal water supply and drainage.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] Design a filtering device for municipal water supply and drainage, including a rotating shaft. A plurality of fixing plates are fixedly arranged on the rotating shaft in a circumferential distribution. A frame is fixed on each fixing plate, and a net pocket is fixed on each frame. A fixing mechanism is fixed on the rotating shaft.

[0006] Preferably, the frame is of a fan-shaped structure.

[0007] Preferably, the fixing mechanism includes a connecting plate. The rotating shaft is rotatably arranged on the connecting plate. A motor is fixedly arranged on the rotating shaft and the connecting plate together. Fixing components are symmetrically fixed on the connecting plate.

[0008] Preferably, the fixing component includes a threaded rod. The threaded rod is fixed on the connecting plate. A cylinder is threadedly sleeved on the threaded rod. A resisting baffle is rotatably arranged on the cylinder.

[0009] Preferably, a supporting mechanism is fixed on the rotating shaft between the connecting plate and the fixing plate.

[0010] Preferably, the support mechanism includes a bearing, the bearing is sleeved and fixed on the rotating shaft between the connecting plate and the fixing plate, a support column is fixed on the bearing, and a bottom plate is fixed on the support column.

[0011] Preferably, a plurality of support plates are equidistantly fixed on the bottom plate.

[0012] A filtering device for municipal water supply and drainage proposed by the present utility model has the beneficial effects that when the filtering device for municipal water supply and drainage is in use, the net bag on one of the frames can block the floating garbage in the underground drainage culvert, thereby filtering out the floating garbage in the sewage in the underground drainage culvert. After using for a period of time, the frames and net bags inserted in the sewage can also be replaced to ensure the filtering effect on the sewage while not blocking the flow of the sewage. The filtered garbage is temporarily stored in the net bag, and the staff can regularly clean up the garbage in the multiple net bags centrally, which can reduce the scattered area for the staff to clean the floating garbage in the sewage in the underground drainage culvert, improve the work efficiency, and reduce the labor intensity at the same time.

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Embodiment 1: Refer to Figure 1 、 24, A filtering device for municipal water supply and drainage, including a rotating shaft 1. A plurality of fixing plates 2 are fixedly arranged on the rotating shaft 1 in a circumferential distribution. A frame 3 is fixedly arranged on each fixing plate 2. The frame 3 is of a sector structure. A net pocket 4 is fixedly arranged on each frame 3. The rotating shaft 1 is coaxially arranged with the underground drainage culvert. The sector-shaped frame 3 and the shape of the underground drainage culvert are more matched. Although the frame 3 will not contact the inner side wall of the underground drainage culvert, when the frame 3 rotates, the distance between the frame 3 and the inner side wall of the underground drainage culvert can always remain the same, which is convenient for the rotation of the frame 3. A fixing mechanism is fixedly arranged on the rotating shaft 1. The fixing mechanism can not only position the position of the rotating shaft 1 at a fixed position of the underground drainage culvert, but also intermittently drive the rotating shaft 1 to rotate, which is convenient for replacing the frame 3 and the net pocket 4 inserted in the water.

[0020] During use, the rotating shaft 1 is coaxially installed in the underground drainage culvert by using the fixing mechanism. At this time, one of the frames 3 and the net pocket 4 on this frame 3 can be inserted into the sewage in the underground drainage culvert. The net pocket 4 on this frame 3 is used to block the floating garbage in the underground drainage culvert, and then filter out the floating garbage in the sewage in the underground drainage culvert. After using for a period of time, the fixing mechanism is used to intermittently drive the rotating shaft 1 to rotate, and then replace the frame 3 and the net pocket 4 inserted in the sewage, which can ensure the filtering effect of the sewage and will not block the flow of the sewage at the same time. The filtered garbage is temporarily stored in the net pocket 4. The staff can regularly clean up the garbage in the multiple net pockets 4 centrally. It can reduce the scattered area of the staff cleaning the floating garbage in the sewage in the underground drainage culvert, improve the work efficiency and reduce the labor intensity at the same time.

[0021] Embodiment 2: On the basis of Embodiment 1, with reference to Figure 1 、 3 4, as another preferred embodiment of the present utility model, different from Embodiment 1, the fixing mechanism includes a connecting plate 8. The rotating shaft 1 is rotatably arranged on the connecting plate 8. A motor 9 is fixedly arranged on both the rotating shaft 1 and the connecting plate 8. Fixing components are symmetrically fixedly arranged on the connecting plate 8. The connecting plate 8 is fixed on the underground drainage culvert by using the fixing components. The motor 9 can intermittently drive the rotating shaft 1 to rotate, and then replace the frame 3 and the net pocket 4 inserted in the sewage.

[0022] The fixing component includes a threaded rod 12, which is fixed on the connecting plate 8. A cylinder 11 is threadedly sleeved on the threaded rod 12. A baffle 10 is rotatably arranged on the cylinder 11. During use, turn the two cylinders 11 to increase the lengths of the two threaded rods 12 protruding from the two cylinders 11 until the two baffles 10 abut against the inner side wall of the underground drainage culvert, and the two cylinders 11 and the two threaded rods 12 are on the same straight line and also on the diameter of the underground drainage culvert. With the support of the two baffles 10, the position of the connecting plate 8 can be fixed in the underground drainage culvert, and then the positions of the multiple frames 3 and the multiple mesh bags 4 can be fixed through the rotating shaft 1. At the same time, the motor 9 can be used to replace the frames 3 and the mesh bags 4 inserted in the sewage.

[0023] Embodiment 3: In Embodiment 2, although the position of the connecting plate 8 can be fixed in the underground drainage culvert by the support of the two baffles 10, the rotating shaft 1 is in a suspended state. At the same time, after the garbage is loaded in the multiple mesh bags 4, the pressure on the rotating shaft 1 will increase, which is not conducive to the motor 9 to stably drive the multiple frames 3 and the multiple mesh bags 4 to rotate intermittently together. Refer to Figure 1 、 3 and 4. As another preferred embodiment of the present invention, the difference from Embodiment 2 is that a support mechanism is fixed on the rotating shaft 1 between the connecting plate 8 and the fixed plate 2. While using the support mechanism to support the rotating shaft 1, it will not affect the rotation of the rotating shaft 1;

[0024] The support mechanism includes a bearing 5, which is sleeved and fixed on the rotating shaft 1 between the connecting plate 8 and the fixed plate 2. A support column 6 is fixed on the bearing 5, and a bottom plate 7 is fixed on the support column 6. A plurality of support plates 13 are equidistantly fixed on the bottom plate 7. After the position of the connecting plate 8 is determined in the underground drainage culvert, the plurality of support plates 13 are in contact with the inner side wall of the underground drainage culvert. The bottom plate 7 and the inner side wall of the underground drainage culvert are separated by the spaces between adjacent two support plates 13. Through the spaces between adjacent two support plates 13, the silt in the sewage in the underground drainage culvert can flow through, and the bottom plate 7 will not block the silt in the sewage in the underground drainage culvert.

[0025] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
