When the filter screen moves to the bottom of the fixed frame, the magnetic block and the iron plate are in contact, which achieves the effect of fixing the filter screen. When the flood discharge is carried out, the staff can take out the filter screen. The filter screen set by the protective device achieves the effect of filtering impurities in the river water, and avoids the situation where impurities in the river water block the gaps of the gate as much as possible.

[0009] Preferably, the filter screen has grooves on both sides, and the inner wall of the fixed frame is fixedly connected to a sliding plate, wherein the sliding plate is slidably adapted to the groove.

[0010] The effect achieved by the above components is that by inserting the sliding plate of the fixed frame into the groove of the filter screen, the movement direction of the filter screen is restricted, thus preventing the filter screen from shaking.

[0011] Preferably, the bottom of the filter screen is fixedly connected to a bottom frame, wherein a retrieval net is fixedly connected inside the bottom frame, and side plates are fixedly connected to both ends of the bottom frame.

[0012] The effect achieved by the above components is that when the filter screen is removed, the retrieval net in the bottom frame retrieves the garbage from the gate, and the side plate limits the garbage to prevent it from falling from both ends of the bottom frame.

[0014] The aforementioned components achieve the following effect: when the filter needs to be disassembled, the worker holds one end of the hook and inserts the barb of the hook into the pull ring. Then, the worker lifts the filter upwards using the hook, and finally the filter is removed from the fixed frame, making it convenient for the worker to remove the filter for cleaning. When the hook is not in use, the worker puts the hook into the storage box for storage. The auxiliary device facilitates the worker's disassembly of the filter and makes cleaning the filter more convenient.

[0015] Preferably, the interior of the placement box is fixedly connected with several Y-shaped frames, wherein the Y-shaped frames can provide support for the hooks.

[0016] The effect achieved by the above components is that the Y-shaped frame supports the hook, keeping it suspended in the air, making it convenient for workers to pick up the hook.

[0017] Preferably, the bottom of the placement box has several drainage holes.

[0018] The above-mentioned components achieve the following effect: by setting drainage holes, rainwater in the placement box is discharged, preventing rainwater from accumulating inside the placement box.

[0019] In summary, the beneficial effects of this utility model are as follows: When the flood is not being discharged, the staff moves the filter screen into the fixed frame. When the filter screen moves to the bottom of the fixed frame, the magnetic block and the iron plate are in contact, which achieves the effect of fixing the filter screen. When the flood is being discharged, the staff can simply remove the filter screen. The filter screen set by the protective device achieves the effect of filtering impurities in the river water, and minimizes the possibility of impurities in the river water clogging the gaps of the gate.
