DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] like Figure 1-6As shown, a low-liquid-level anti-vortex fire filter proposed in one embodiment of the utility model, the low-liquid-level anti-vortex fire filter designed in this scheme can adjust the overall height of the filter according to different water level conditions to meet different usage environments and realize the adjustment of the filter screen gap. When used in different water surface environments, it is adjusted to increase the amount of water inlet. It includes a base 1, a guide member 2, a protective member 3, a spacing adjustment member 4 and a connecting pipe 5. The base 1 is fixedly connected with the guide member 2, the guide member 2 is rotatably connected with the protective member 3, the protective member 3 is arranged in contact with the base 1, the guide member 2 is slidably connected with the spacing adjustment member 4, and the spacing adjustment member 4 is connected to the base 1. The joint member 4 is sleeved on the connecting pipe 5, and the connecting pipe 5 is fixedly connected to the base 1 and the guide member 2. The connecting pipe 5 is threadedly connected with a lifting member 6, and the lifting member 6 is rotatably connected to the spacing adjustment member 4. When the liquid level environment is low, the adjusting ring 601 is rotated and raised on the threaded section 503 to adjust the adjustment ring 601. Since the rotating convex ring 602 is rotatably connected to the second rotating groove 404, and the sliding groove 402 between two adjacent baffles 401 slides against the guide plate 204, when the adjusting ring 601 is rotated and raised, the spacing adjustment member 4 can be vertically lifted and lowered. The shape of the baffle 401 is as follows: Figure 5 As shown, when the baffle 401 descends, the gap between two adjacent connecting rods 504 and two adjacent guide plates 204 can be blocked through the solid part at the corner of the baffle 401, ensuring that the gap between the two places will not affect the use of pumping water when pumping water. Through the design of the guide plate 204, the pumping point of the pipe column 501 can be spread to all directions, and the problem of vortex will not occur due to the concentration of the water inlet, thereby improving the anti-vortex use effect. When used in different water surface environments, the gap between the filter screens of the device can be adjusted, so that when the impurities in the water are relatively large and small, the gap between the filter screens can be adjusted to be smaller to improve the filtering effect. When the impurities in the water are relatively large and small, the gap between the filter screens can be adjusted to be smaller to improve the filtering effect. The outer ring 301 can be rotated at this time, and the ring piece 302 can be rotated and adjusted in the first rotating groove 202 to control the overlap state of the second blocking column 303 and the first blocking column 102. After the adjustment is completed, the bolt 203 is tightened to fix the position of the ring piece 302. When the ring piece 302 overlaps with the first blocking column 102, the gap between the filter screen of the combination of the two is the largest. When the two are misaligned, the gap can be relatively reduced, thereby satisfying the adjustment and use under different filtering environments.
