secondly, the locking frame 3 is driven to move leftwards by the moving frame 2, the lower T-shaped rod 42 is firstly contacted with the shaking groove 75 on the outer side, the T-shaped rod 42 moves to the upper side face of the shaking support 71 under the guiding action of the shaking groove 75, and simultaneously the lower pressing guide plate 74 is driven to move upwards, so that the telescopic elastic column 73 is compressed, the lower T-shaped rod 42 moves to the shaking groove 75 on the inner side along with the continuous movement of the heat storage element, the T-shaped rod 42 rapidly moves downwards under the downward pressure action of the telescopic elastic column 73 in the square structure of the shaking groove 75, so that the heat storage element is shaken greatly, impurities in the heat storage element can be shaken off by the shaking mode, and then the heat storage element moves to the position of the wavy groove to be shaken circularly;
thirdly, when the heat storage element moves to the position right below the water spraying gun 6, the pushing push rod 53 is controlled to perform extension movement, the pushing push rod 53 drives the U-shaped structure of the sleeving piece 56 to be sleeved outside the T-shaped rod 42 at the lower end, meanwhile, the jacking seat 542 can synchronously move inwards, and the jacking inclined groove 543 in the jacking seat 542 can guide the jacking rod 47, so that the jacking rod 47 moves to the upper side face of the jacking seat 542 along the jacking inclined groove 543; at the moment, the middle part of the upper end of the heat storage element corresponds to the axial lead of the T-shaped rod 42 at the upper end, and the position relation ensures that the upper end of the heat storage element only changes in angle and does not change in position, thereby increasing the cleaning effect of the heat storage element;
fourthly, controlling the water spraying gun 6 to flush the heat storage element, and simultaneously, shaking the push rod 55 to perform telescopic motion so that the sleeving piece 56 drives the T-shaped rod 42 at the lower end to swing left and right;
fifthly, after the heat storage elements are washed, the water spray gun 6 is turned off, the shaking push rod 55 and the pushing push rod 53 are controlled to sequentially return to the initial positions, then the moving frame 2 is controlled to continuously carry out stepping motion, the rest heat storage elements are continuously washed, and the washed heat storage elements are shaken off by cleaning fluid through the wavy grooves and the shaking grooves 75 in sequence;
sixthly, after all the heat storage elements are washed, controlling the rotating motor 22 to turn over the locking frame 3, washing the bottoms of the heat storage elements in sequence, and increasing the cleaning effect of the heat storage elements through multi-angle washing at the upper end and the lower end.
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.
