when in use, the device is firstly placed in seawater, then the vertical mixed flow pump 1 is started to pump out water flow, meanwhile, the vertical mixed flow pump 1 is fixedly connected with the source battery 31 and the anode block 32 through the cable 33, then a closed circuit is formed under the action of the seawater, the source battery 31 provides current, and further the potential of the surrounding environment is changed, the potential of the vertical mixed flow pump 1 is always in a state lower than the surrounding environment, so that the vertical mixed flow pump becomes a cathode in the whole environment, and further the purpose that the vertical mixed flow pump 1 cannot be corroded due to electron loss is realized, the traditional coating corrosion prevention mode is changed, thereby solving the problems that the traditional corrosion prevention structure mainly adopts the mode of coating the surface of the mixed flow pump, and the mixed flow pump is easy to leak in the processes of long-term use and maintenance, and further the steel structure of the main body of the mixed flow pump is directly exposed in seawater medium, thereby causing a problem that the anticorrosive effect cannot be maintained.
Further, when the vertical mixed-flow pump 1 pumps seawater, the fan blade rod 52 is driven to rotate by the flowing action of water flow, and the fan blade rod 52 rotates and drives the poking block 533 to compress the second spring 534 to slide on the sliding rheostat 532 by the action of centrifugal force of the fan blade rod, so that the internal resistance value of the sliding rheostat 532 is changed, the pumping-out speed of the water flow is in an inverse relation with the internal resistance value of the sliding rheostat 532, and the current magnitude of the source battery 31 introduced into the circuit is in a positive relation with the pumping-out speed of the water flow due to the fact that the sliding rheostat 532 is electrically connected with the source battery 31, so that the current magnitude can be reasonably distributed and supplied according to the corrosion degree of the vertical mixed-flow pump 1, and the corrosion prevention effect is further improved.
Further, when water flows from the front side to the rear side of the cylinder 51 into the vertical mixed flow pump 1, the water flow around the cylinder 51 has potential energy flowing backwards, so that part of the water flow can flow into the water inlet pipe 342 through the filter plate 343, since the filter plate 343 is provided with uniformly distributed filter holes, most impurities in the water can be filtered when the external water flow enters the water inlet pipe 342, the water flow inside the water inlet pipe 342 enters the branch pipe 351 through the flow guide main pipe 341, since the branch pipe 351 is internally provided with uniformly distributed tapered pipes 352, the pipe diameter of the tapered pipe 352 tends to be gradually reduced from the right side to the left side, the water flow flows out from the large hole and the small hole, so that the flow rate of the water flow is increased, and since the branch pipe 351 corresponds to the gap between the adjacent long blocks arranged on the anode block 32, when the water flow flows to the gap between the long blocks, rivers bump with lug 453 for rivers carry out high-efficient impact to the contained angle department between rectangular piece and the lateral pipe 351, and then have realized that the rivers that lateral pipe 351 flows can carry out the purpose effectively clear away to the impurity of the clearance department between the adjacent rectangular piece.
Further, when the bulk impurities cling to the long blocks of the anode block 32, the water pressure at the gap between the adjacent long blocks is increased, because the pressure switch 454 is electrically connected with the coil 42, when the pressure switch 454 senses the pressure change signal, the current in the intermittent change direction is controlled to be introduced into the coil 42, so that the coil 42 intermittently generates the magnetic force repelling or attracting the magnetic rod 44, the magnetic rod 44 is driven to move back and forth, the purpose that the magnetic rod 44 drives the rotating rod 451 and the cleaning rod 452 to rotate back and forth is realized, the effect of comprehensively cleaning the bulk impurities is achieved, and the problem that the surface of the anode is easy to stack a large amount of impurities to block the cathode protection work is solved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
