step two: through the arrangement of the connecting assembly 2, the first semicircular ring 11 and the second semicircular ring 12 are separated firstly, then the first semicircular ring 11 and the second semicircular ring 12 are sleeved outside the branch pipe 10, and then the locking bolt 15 penetrates through the first top plate 13 and the second top plate 14 to reinforce the first semicircular ring 11 and the second semicircular ring 12, so that the stability of the first semicircular ring 11 and the second semicircular ring 12 is ensured, the subsequent protective cover 5 and the control unit 6 can be positioned, the whole assembly is convenient to disassemble, and the water meter can be quickly adapted to different water meter main bodies 1 for use;

step three: by providing the engaging member 4, the engaging block 24 is mounted on the top end of the threaded rod 22, the engaging plate 25 is brought close to the engaging block 24, and then the engaging block 24 is preliminarily fixed by passing through the through hole 26 of the engaging plate 25, the protection cover 5 can be preliminarily positioned, and after the preliminary positioning in cooperation with the reinforcement part 27, under the pushing of the reinforcing spring 31, the two groups of reinforcing heads 30 are linked to slide in the reinforcing cavity 28, so that the reinforcing heads 30 are correspondingly inserted into the reinforcing grooves 29 for fixing, the clamping block 24 and the clamping plate 25 can be fixed, the situation that the clamping block 24 falls off accidentally is avoided, when the disassembly is needed subsequently, the two groups of linkage plates 32 are extruded towards the middle part, the two groups of reinforcing heads 30 are linked to collapse in the reinforcing cavity 28, the reinforcing head 30 is separated from the reinforcing groove 29, and the clamping block 24 can freely slide in the through hole 26, so that the protective cover 5 can be quickly disassembled by workers, and the whole installation and disassembly are convenient;

step four: by arranging the extension component 3, the extension sleeve 20 slides in the extension cavity 16 along with the sliding plate 17, so that the elastic installation of the protective cover 5 is realized, the adaptability of the protective cover 5 is better, the external impact force on the protective cover 5 can be absorbed under the clamping of the buffer spring 18, the control unit 6 is protected, and under the assistance of the extension part 19, the threaded rod 22 is rotated and connected with the adjusting nut 23 in a screwing manner, so that the threaded rod 22 moves up and down in the adjusting cavity 21, the height of the protective cover 5 can be adjusted, the protective cover can be quickly adapted to different water meter main bodies 1 for installation and use, and the overall adaptability of the equipment is improved;

step five: through being equipped with position control assembly 7, rotate carousel 35, drive and extend threaded rod 34 and rotate, because extend threaded rod 34 and screw block 36 and close soon through the screw thread and be connected, drive the control unit 6 and follow screw block 36 and carry out the horizontal slip in protection casing 5 top, increased the working range of control unit 6, can carry out dynamic adjustment according to the in-service use demand to the operating position of control unit 6, strengthened whole information and obtained the precision.

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.
