Description

Rotary filter screen sacrificial anode clamp

Technical Field

The utility model belongs to the anticorrosive field of ocean metal especially relates to a rotary filter screen sacrificial anode's anchor clamps.

Background

Marine metal structures such as ocean platforms, submarine pipelines, harbor wharfs and the like are usually protected from corrosion damage by sacrificial anode cathodic protection measures in severe marine corrosion environments. The three layers of sacrificial anodes below the rotary filter screen are respectively immersed in the seawater for 3m, 6 m and 8m, so that the function of protecting the filter screen frame against seawater corrosion is achieved. The sacrificial anode is immersed in seawater, the service life of the sacrificial anode is generally 2-3 years, and the sacrificial anode needs to be replaced periodically. At present, when an underwater filter screen is frequently checked, the sacrificial anode is corroded, the filter screen frame is seriously corroded, a plurality of 2-3mm pits are formed in an 8mm angle steel frame, hidden dangers are brought to the operation of the filter screen, the sacrificial anode welded on the filter screen frame causes the problem that a diver cannot freely change the sacrificial anode, a seawater system operates for 6 years, the work that the stop log gate track is seriously corroded, seawater in a filter screen pool can be pumped out completely through the upper ramp gate is large in workload, and whether the performance is uncertain, and 16 tons of aluminum screens weighing 15 meters in height are lifted out more difficultly.

Disclosure of Invention

In order to overcome the defect that the sacrificial anode in the prior art is difficult to replace and the replacement cost is too high, the utility model provides a rotary filter screen sacrificial anode clamp, which enables underwater divers to replace the sacrificial anode regularly and conveniently and protect the use function of the rotary filter screen.

In order to achieve the above object, the utility model adopts the following technical scheme: the rotary filter screen sacrificial anode clamp comprises an outer fixing clamp, an inner fixing clamp, rotary filter screen frame supporting angle steel and a clamp fixing bolt; the outer fixing clamp and the rotary filter screen frame support angle steel are L-shaped, the inner fixing clamp is L-shaped, and the two sides of the inner fixing clamp are provided with the clamp fixing bolts; the outer fixing clamp is sleeved outside the rotary filter screen frame supporting angle steel, the inner fixing clamp is arranged in the rotary filter screen frame supporting angle steel, the outer fixing clamp and the inner fixing clamp are fixed on the rotary filter screen frame supporting angle steel through the clamp fixing bolts, the outer fixing clamp and the inner fixing clamp are stacked through the clamp fixing bolts, and when the sacrificial anode is replaced, the seawater sacrificial anode is hung on the screw rod of the left clamp fixing bolt through the nut of the left clamp fixing bolt, and then the seawater sacrificial anode is fixed through the fastening nut.

Furthermore, the anode clamp is made of 316L stainless steel, and the bolt is made of 2205 duplex steel.

The utility model has the advantages that: the sacrificial anode is simple and convenient to replace, can be replaced in a short time, and improves the safety and the high efficiency of underwater operation; the material is easy to obtain and manufacture, and manpower and material resources are saved; the anode clamp material has good corrosion resistance, almost does not consume the anode clamp in the long-term use process, and has durability.

Detailed Description

The present invention will be described in detail with reference to the following embodiments, but the scope of the invention is not limited thereto. Unless otherwise stated, the experimental methods adopted by the utility model are all conventional methods, and experimental devices, materials, reagents and the like can be obtained from commercial sources.

Example 1

Rotary filter screen sacrificial anode anchor clamps are including outer fixation clamp 1, interior fixation clamp 2, rotary filter screen frame support angle steel (3), anchor clamps fixing bolt A5, anchor clamps fixing bolt B6.

The installation steps are as follows: the method comprises the steps that an external fixing clamp 1 in a picture 1 is sleeved on the outer side of a rotary filter screen frame supporting angle steel 3, an internal fixing clamp 2 is arranged on the inner side of the rotary filter screen frame supporting angle steel 3, the external fixing clamp 1 and the internal fixing clamp 2 are fixed to the rotary filter screen frame supporting angle steel 3 through a clamp fixing bolt A5 and a clamp fixing bolt B6, and then a nut of the clamp fixing bolt A5 is loosened to fix a seawater sacrificial anode 4 through the clamp fixing bolt A5. The seawater sacrificial anode 4 is fixed on the rotary filter screen frame support angle steel 3 through fixing clamps arranged at two ends. When the seawater sacrificial anode 4 is replaced, the seawater sacrificial anode 4 is hung on the screw rod of the fixture fixing bolt A5 only by loosening the nut of the fixture fixing bolt A5 and screwing the nut of the fixture fixing bolt A5, so that the replacement of the seawater sacrificial anode 4 can be completed.

The embodiments described above are only preferred embodiments of the present invention, and are not all possible embodiments of the present invention. Any obvious modifications to the above would be obvious to those of ordinary skill in the art, but would not bring the invention so modified beyond the spirit and scope of the present invention.
