Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] This utility model provides, for example Figure 1-3 The self-cleaning municipal water supply and drainage filtration device shown is an example. Example

[0037] The cover plate 1 has equidistant filter channels on its top, which facilitates water to enter and exit the channels. A filter screen 3 is embedded in the inner cavity of the filter channels to facilitate filtration and prevent impurities from clogging the channels. A top block 2 slides through the inner cavity of the filter channels. A shielding mechanism 4 is located on the top of the cover plate 1 and is used to shield large areas of impurities. The filter device is installed at the pipe opening so that when water flows into the pipe and enters the pipe, impurities are filtered. The bottom of the filter device is placed inside the pipe.

[0038] Furthermore, the shielding mechanism 4 includes a first plate 41, a side extension plate 43, a short plate 44, and a lifting column 45. The first plate 41 and the second plate 42 are conducive to supporting the side extension plate 43 and the short plate 44, facilitating their installation. The side extension plate 43 and the short plate 44 are also conducive to supporting the lifting column 45, facilitating its use. The lifting column 45 is conducive to blocking large-area impurities flowing through, preventing them from directly blocking the filter screen 3, and also facilitates the water to directly pass through the large gap, allowing the water to drain quickly. The second plate 42 is provided on the side of the first plate 41. Both the first plate 41 and the second plate 42 are located above the top block 2. The side extension plate 43 is fixedly connected to the first plate 41 and the second plate 42, the short plate 44 is fixedly connected to the second plate 42, and the lifting column 45 is fixedly connected to the top of the side extension plate 43 and the short plate 44.

[0039] Furthermore, the shielding mechanism 4 also includes a connector and a positioning member. The connector is located at the bottom of the first plate 41 and is used to lock the installation position of the first plate 41. The positioning member is located at the bottom of the second plate 42.

[0040] Specifically, the positioning components include a first column 46, a support plate 413, and a positioning rod 414. The first column 46 provides support for the second plate 42, the support plate 413 provides support for the first column 46, and the positioning rod 414 connects to the support plate 413, thereby facilitating the positioning of the second plate 42 and increasing the stability of the second plate 42 installation. The first column 46 is fixedly connected to the bottom of the second plate 42, the support plate 413 is fixedly connected to the bottom of the first column 46, and the positioning rod 414 is fixedly connected to the top of the cover plate 1. The outer wall of the positioning rod 414 is slidably inserted into the support plate 413.

[0041] Specifically, the connector includes a second column 47, a positioning plate 49, and a limiting block 410. The second column 47 facilitates the support of the first plate 41, making it easier to install. The positioning plate 49 facilitates connection with the assembly frame 48, thereby facilitating the installation of the first plate 41 and its positioning with the cover plate 1. The limiting block 410 limits the relative position of the assembly frame 48 and the positioning plate 49, thereby facilitating the installation and disassembly of the first plate 41 and the large area to be covered. The accumulated impurities are removed and the lifting column 45 is removed and cleaned. The second column 47 is fixedly connected to the bottom of the first plate 41. The bottom end of the second column 47 is fixedly connected to the assembly frame 48, which facilitates connection with the positioning plate 49. The positioning plate 49 is fixedly connected to the top of the cover plate 1. The positioning plate 49 and the inner cavity of the assembly frame 48 are slidably inserted and connected. The side of the assembly frame 48 is provided with a slot that matches the limiting block 410. The side of the positioning plate 49 is provided with a limiting groove that matches the limiting block 410.

[0042] The self-cleaning principle of the municipal water supply and drainage filtration device is consistent with the prior art mentioned in the background technology, so the specific structural diagram is not shown. As follows: When the filter channel is blocked by impurities, the water flow to the baffle gradually decreases. When it decreases to less than the water flow unblocking speed at the drain pipe, the water level in the water tank gradually drops and the weight decreases. The spring in the spring telescopic rod experiences less force and gradually returns to its original state, pulling the baffle upward. The baffle then drives the slider to move upward, causing the top block 2 to extend out of the upper opening of the filter channel, lifting the impurities. The subsequent water flow washes away the impurities. After the filter channel is unblocked, the baffle drops to the lowest position to ensure maximum unblocking force. No manual cleaning is required, and it can automatically clean impurities. Example

[0043] Based on Embodiment 1, the connector also includes a support base 411 and a threaded post 412. The support base 411 facilitates the rotation of the threaded post 412 on it, thereby providing rotational support for the threaded post 412. The threaded post 412 facilitates the movement of the limiting block 410, allowing the limiting block 410 to connect or disconnect from the positioning plate 49, thereby enabling the installation and disassembly of the first plate 41. The support base 411 is fixedly embedded in the slotted inner cavity, and the threaded post 412 is threadedly inserted into the inner cavity of the support base 411. The end of the threaded post 412 is rotatably connected to the side of the limiting block 410.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
