Specifically, when fixing aqueduct 7 and sleeve 5 threaded connection, water inlet connector 94 joint enters into in the wash port 97, make water inlet connector 94 and wash port 97 intercommunication, water inlet connector 94 includes movable rod 941, shutoff board 942, conflict head 943 and extrusion spring 944, a plurality of mounting hole 945 has been seted up to sleeve 5 inside, movable rod 941 is the horizontal slip setting in mounting hole 945, shutoff board 942 is fixed in movable rod 941 tip, and shutoff board 942 is along mounting hole 945 inner wall sealing sliding fit, the inside cavity that all is of shutoff board 942 one side of contact 943, shutoff board 942, conflict head 943 and movable rod 941, the tip of conflict head 943 is the arc form, extrusion spring 944 movable sleeve is established on movable rod 941, extrusion spring 944 both ends are inconsistent with shutoff board 942 and mounting hole 945 respectively.
When the water inlet connector 94 is clamped into the drain hole 97, the pressing spring 944 in the mounting hole 945 pushes the plugging plate 942, so that the abutting contact 943 is driven to enter the drain hole 97.
Further, the drain hole 97 is adapted to the abutting head 943, and a rubber blocking 946 is provided inside the drain hole 97.
The drain hole 97 in the initial state is provided with the rubber seal 946, therefore, even if the inside water flow of the water guide pipe 7 circulates, the water flow can not be caused to flow out from the drain hole 97, and when the contact 943 enters into the drain hole 97, the contact 943 enters into the drain hole 97 under the pushing of the compression spring 944, and the contact 943 is arc-shaped, and can push the rubber seal 946 to open, so that the drain hole 97 is communicated with the movable rod 941, and then the water flow inside the water guide pipe 7 is conveyed into the rubber air bag 91, so that the rubber air bag is inflated.
Therefore, when the water source enters the inside of the water guide pipe 7, firstly, the water enters the inside of the rubber air bag 91 through the water discharge hole 97 until the water flows fully open the rubber air bag 91, after the rubber air bag 91 is opened, all the arc-shaped L-shaped seats 96 can be pushed to be dispersed and removed from the circumferential direction of the mounting groove 95 until all the cleaning scraping blades 93 are abutted against the inner wall of the conveying pipe 1, and after the inside of the rubber air bag 91 is filled with the water flow, the water inside the water guide pipe 7 subsequently enters the inside of the fixing seat 4, so that all the spray heads 8 can uniformly spray water and flush the inner wall of the conveying pipe 1.
The cleaning blades 93 are arranged in an arc-shaped inclined manner, and the head ends and the bottom ends of the cleaning blades 93 are respectively located right above and right below two adjacent cleaning blades 93.
Through the structure, all the cleaning scraping blades 93 are divided into a plurality of groups, each group of cleaning scraping blades 93 is arranged in an arc-shaped inclined manner, so that gaps are tightly and not formed in the connection between every two adjacent cleaning scraping blades 93, when the fixing seat 4 moves upwards, the cleaning scraping blades 93 are abutted against the outer wall of the conveying pipe 1, along with the upward movement of the fixing seat 4, the cleaning scraping blades 93 move upwards to scrape concrete, the cleaning scraping blades 93 and the spray head 8 cooperate to effectively clean the concrete attachments on the inner wall of the conveying pipe 1, and accordingly the cleaning effect of the conveying pipe 1 is achieved, the conveying pipe 1 is not damaged and is rapid and effective, and due to the arrangement of the rubber air bags 91, the embodiment is convenient for the conveying pipe 1 with different diameters, the rubber air bags 91 are internally provided with water pressure, so that the cleaning scraping blades 93 can be abutted against the inner wall of the conveying pipe 1 better, and the cleaning scraping blades 93 are prevented from scraping the inner wall of the conveying pipe 1.
It should be noted that, in order to better drain the water flow, a filter screen may be disposed at the bottom of the arc-shaped L-shaped seat 96 to drain the water flow, and the scraped slag may be filtered, and poured out after the cleaning of the conveying pipe 1 is completed.
When all the arc-shaped L-shaped seats 96 are pushed out, gaps exist between two adjacent arc-shaped L-shaped seats 96, therefore, through setting up the locating component 92 between the two, through the cooperation of locating component 92 and cleaning wiper 93, avoid concrete to pass from the gap, avoid the incomplete condition of concrete cleaning to take place, the locating component 92 includes fixed plate 921, movable riser 922, inclined wiper 923, push rod 924 and reset spring 925, fixed plate 921 is fixed to be set up inside mounting groove 95, the spout has been seted up to fixed plate 921 inside, push rod 924 is the horizontal slip setting in the spout, movable riser 922 and inclined wiper 923 are fixed respectively at push rod 924 both ends, movable riser 922 one side and rubber bag 91 outer wall fixed connection, reset spring 925 movable sleeve is established on push rod 924, reset spring 925 both ends are inconsistent with movable riser 922 and fixed plate 921 respectively.
When the rubber air bag 91 is inflated, the movable vertical plate 922 can be pushed to move to squeeze the reset spring 925, meanwhile, the movement of the movable vertical plate 922 drives the push rod 924 to horizontally move inside the fixed plate 921, so that the inclined vertical plate 923 is driven to move to abut against the inner wall of the conveying pipe 1, the width of the inclined vertical plate 923 can be set according to the width of the cleaning scraping blades 93 on two sides of the inclined vertical plate 923, larger gaps are avoided between two adjacent arc-shaped L-shaped seats 96, when the cleaning scraping blades 93 move upwards, the inclined vertical plate 923 also synchronously moves upwards to scrape concrete, after the conveying pipe 1 is cleaned, water supply is stopped inside the water guide pipe 7, air enters inside the water guide pipe 7, water flow inside the rubber air bag 91 enters inside the water guide pipe 7 from the movable rod 941 through the water drain hole 97, after the movable vertical plate 922 loses the abutting pressure from the rubber air bag 91, the reset spring 925 resets, the movable vertical plate 922 is pressed to move to reset, the movable vertical plate 922 is driven to shrink the rubber air bag 91 fixedly connected with the movable vertical plate, and all the arc-shaped L-shaped seats 96 are accordingly retracted inside the installation grooves 95, and the movable vertical plate 93 can be conveniently removed from the port of the conveying pipe 1.
Because the same water source is used by the spray head 8 and the rubber air bag 91, in order to prevent that the water flow in the rubber air bag 91 can reversely flow to the inside of the fixed seat 4 through the water drain hole 97 when the spray head 8 is used, the movable plate 41 is arranged in the fixed seat 4, the bottom of the movable plate 41 is fixedly connected with the fixed cylinder 42, the fixed cylinder 42 is arranged in the sleeve 5 in a sliding manner in the vertical direction, the fixed cylinder 42 is in sliding connection with the water guide pipe 7, the top of the movable plate 41 is fixedly connected with the compression spring 43, and the top of the compression spring 43 is fixedly connected with the fixed seat 4.
