The flat water inlet head 21 is connected with other equipment through a rotary joint 211, and the water inlet head 21 can rotate under the action of an external driving mechanism. The water inlet head 21 in a rotating state can stir the water body, so that the water inlet holes 22 are prevented from being blocked, and the water bodies in different water layers of rivers and lakes can be uniformly pumped.
The driving plate 212 is movably arranged in the water inlet head 21, and the driving plate 212 can reciprocate along the water flow direction (arrow direction in the state shown in fig. 12) of the water inlet head 21 under the driving of the driving assembly; the driving plate 212 is provided with an insert rod 213, and the insert rod 213 is substantially coaxial with the water inlet hole 22.

The first wheel 216 can rotate under the action of the water flow, the first wheel 216 drives the first shaft 222 to rotate, and the first shaft 222 drives the cam 217 to rotate. During the rotation of the cam 217, the driving plate 212 can be pushed to the left by the driving plate 214 through the link 221, and after the driving plate 212 moves to the left, the driving plate can be reset to the right by the reset spring 219. In the process that the driving plate 212 moves to the left, the inserting rod 213 can be inserted into the water inlet hole 22 to dredge the water inlet hole 22 and prevent the water inlet hole 22 from being blocked.
In one implementation scenario, the water inlet head 21 includes a water inlet head main body 21a and a cover plate 21b covering the water inlet head main body 21a, and the cover plate 21b is located on the water facing side of the water inlet head 21, so that even if the cover plate 21b covers the water inlet head main body 21a, the cover plate cannot easily fall off from the water inlet head main body 21a, and the normal operation of the water inlet head is not affected. Furthermore, it should be understood that the cover mechanism described herein may be, but is not limited to, an interference fit, which is sufficient to ensure that the cover plate 21b does not fall off freely from the inlet head body 21a when the cover plate 21b is mounted on the inlet head body 21a by means of interference fit.
According to the above technical solution, the driving plate 212, the bracket 215 and other components in the water inlet head 21 can be directly mounted on one side of the cover plate 21 b.

Example 2
One common design for rivers and lakes is to arrange them in a closed loop configuration (i.e., a river and lake connected end to end in a ring shape with an island in the middle) and also in a radial configuration (e.g., Jiaxing south lake). The water in rivers and lakes in a closed-loop structure is usually dead water and is in a static state for a long time. In rainy days, the rain water can wash the earth surface and carry organic matters and nitrogen and phosphorus elements to flow into rivers and lakes; in addition, the atmospheric dust fall also removes organic matters and nitrogen and phosphorus elements from rivers and lakes. Organic matters and nitrogen and phosphorus elements are continuously accumulated in rivers and lakes along with the lapse of time, so that water bodies of the rivers and lakes are eutrophicated, and further, algae are massively propagated in the rivers and lakes.
In order to deal with the above situation, the present embodiment provides a river and lake water area device, which employs the intake anti-blocking device provided in embodiment 1, and due to the existence of the intake anti-blocking device, the river and lake water area treatment device can continuously and effectively operate.
The present embodiment will be described in detail with reference to fig. 1 to 15.
As shown in fig. 1 to 4, an embodiment of the invention provides river and lake water area equipment. The processing apparatus includes: a water retaining piece 1 for cutting off rivers and lakes, a reaction tank 2 and a purification tank 3 which are communicated with each other, a feeding device for adding coagulant, magnetic seeds and coagulant aid into the reaction tank 2, and a super-magnetic separation device 4 arranged in the purification tank 3; wherein, the reaction tank 2 is adapted with a water pump 5 for pumping water from rivers and lakes on one side of the water blocking member 1, and the purification tank 3 is provided with a drainage weir 6 for draining water to rivers and lakes on the other side of the water blocking member 1. It should be understood that the reaction tank 2 and the purification tank 3 can be arranged on the banks at both sides of the river and lake or in the river and lake; the reaction tank 2 and the purification tank 3 are arranged in rivers and lakes more preferably, so that the environment can be beautified, the occupation of the ground of a river bank is reduced, people can walk along the river bank conveniently, and the rivers and lakes can be enjoyed. The supermagnetic separation device 4 generally comprises a magnetic disc, a slag scraping strip, a planing strip and a spiral conveying mechanism; the magnetic floccules are adsorbed by the magnetic disc, the magnetic floccules on the magnetic disc are led into the spiral conveying mechanism through the slag scraping strip and the planing strip, and mud residues formed by gathering the magnetic floccules are discharged through the spiral conveying mechanism, so that the magnetic floccules in the purifying tank 3 are removed. With regard to the specific structure and operation principle of the supermagnetic separation device 4, reference may be made to another patent previously filed by the applicant, whose disclosure numbers are: CN211445175U, patent number: ZL201921593627.7, name: a supermagnetic separator is not described herein. Of course, the structure of the supermagnetic separation device 4 used in the present application is not limited to the supermagnetic separation device disclosed in the aforementioned patent, and the supermagnetic separation device may have other structures.
In the following, the embodiment of the invention is explained, the water pump 5 pumps water from the river or lake on one side of the water blocking piece 1 and pumps the water into the reaction tank 2; the feeding device can continuously add coagulant, magnetic seeds and coagulant aid into the reaction tank 2, and pollutants such as organic matters, total phosphorus and the like in the water body can form magnetic floccules under the action of the coagulant, the magnetic seeds and the coagulant aid; then, the magnetic floccules flow into the purifying tank 3 along with the water body, and the super-magnetic separation device 4 arranged in the purifying tank 3 removes the magnetic floccules from the water body, thereby completing the purification of the water body. The purified water body overflows from the drainage weir 6 to the river and lake on the other side of the water retaining member 1, flows along the closed-loop river and lake and flows back to the water pumping side of the water retaining member 1 again. Therefore, the water body of the river and the lake can be continuously purified. The invention is suitable for closed-loop rivers and lakes, and can purify the water bodies of the rivers and lakes, thereby preventing or treating the eutrophication of the rivers and lakes. It should be noted that when the river and lake water body purification equipment provided by the embodiment is applied to rivers and lakes with closed loop structures, the effect is better; the river and lake water body purification equipment provided by the embodiment can also be applied to river and lake water body treatment of Jiaxing south lake. The two application scenarios are different in that: for rivers and lakes which are not in a closed loop structure, the purified water body can not flow back to the water pumping side of the water retaining member 1.
