In order to realize installation and use, the ball valve 3 comprises a valve body, a ball body arranged in the valve body and a valve rod 9 connected with the ball body, wherein the valve rod 9 can drive the ball body to rotate clockwise or anticlockwise by any angle.
In order to stably supply water and spray, the water supply system 1 consists of a water pump and a towerless water supply pressure tank, a pipeline 2 is connected to an outlet of the towerless water supply pressure tank, the pipeline 2 is connected with a plurality of branch pipes through a three-way valve, spray heads are installed on the branch pipes, and the branch pipes are laid above the precast beam.
The present invention is used in a state that, when it is used for the first time, the device needs to be arranged, specifically, a plurality of branch pipes are respectively laid above the precast beam and are arranged uniformly as much as possible, then the pipeline 2 is connected to the water supply system 1, and the timing valve is installed on the pipeline 2, the ball valve 3 is located on the left side of the shell 4, and the installation example that water flows through the impeller 7 from the ball valve 3 is explained, and the principle of other installation modes is similar.
Before use, the valve is in an open state, and meanwhile, the torsion spring 11 on the driven wheel 10 has little torsion force, so that the valve can be kept in the open state; the inner end of the stop lever 15 positioned at the front of the two stop levers 15 can block the shift lever 12 (to make the valve unable to rotate), and the outer end of the stop lever 15 is contacted with the inner edge surface of the gear ring 14, is not positioned in the corresponding groove and is positioned at the left side of the groove; the outer end of the stop lever 15 which is positioned relatively backward in the two stop levers 15 is arranged in the groove at this time, and the inner end of the stop lever 15 does not block the shift lever 12; before the entire timing valve is used, the rack 16 will now be in a state of non-contact with the ring gear 14, with the rack 16 at the rightmost end of its travel and engaging the partial gear 17.
After the device is arranged, the tower-free water supply pressure tank in the water supply system 1 can be opened, at the moment, the valve core (namely the ball body) of the ball valve 3 is in an unblocked state, so that water can pass through the ball valve 3, meanwhile, the water can flow into the shell 4 from the ball valve 3 and is conveyed into each branch pipe through the pipeline 2, and the precast beam is sprayed.
When the water flow moves the impeller 7, due to the action of the water pressure (the pressure range of the towerless water supply pressure tank is 1.5bar to 10 bar), the water flow pushes the impeller 7 to rotate (hereinafter, the counterclockwise rotation of the impeller 7 is referred to as reference), and at this time, the impeller 7 drives the driving wheel 8 and the incomplete gear 17 to rotate simultaneously through the rotation.
When the driving wheel 8 rotates, firstly, the driven wheel 10 can rotate due to the meshing relationship of the driving wheel 8, the intermediate wheel 23 and the driven wheel 10, and at this time, the stop lever 15 at the front side is still in a state of blocking the shift lever 1212, so that when the driven wheel 10 rotates, the valve rod 9 cannot rotate, and the torsion spring 11 is twisted, and meanwhile, because the ratchet wheel 21 is fixedly connected to the driven wheel 10, the ratchet wheel 21 also rotates along with the driven wheel 10 at this time, and reverse rotation cannot be generated; make torsional spring 11 by continuous torsion, and produce sufficient power, when torsional spring 11's crescent, the power that rotates from driving wheel 10 this moment can not continuous increase yet, when torsional spring 11's power is enough big, the power that rotates from driving wheel 10 needs this moment is also enough big, consequently action wheel 8 can not drive from driving wheel 10 and rotate this moment, this moment because install mechanical overload between action wheel 8 and the follow driving wheel 10, be located the extrusion of the recess on the second pin 20 of pivot 6 receives action wheel 8 inner fringe face promptly, after action wheel 8 atress is too big, the pin can be extruded to the blind hole in pivot 6, make the pin can not drive action wheel 8 and rotate, pivot 6 can rotate alone this moment.
When the incomplete gear 17 rotates, the incomplete gear 17 is meshed with the rack 16 to enable the rack 16 to gradually move leftwards, the gap between two adjacent teeth of the rack 16 and the number of teeth of the incomplete gear 17 can be controlled to control the speed of the leftward movement of the rack 16, meanwhile, a second pin 20 is arranged between the driving wheel 8 and the rotating shaft 6 and has a certain friction effect, so that the rotating speed of the driving wheel 8 can be controlled, the speed of the leftward movement of the rack 16 can also be controlled, meanwhile, under the action of a planetary gear train, the rotating speed of the incomplete gear 17 can be greatly reduced, so that the rack 16 can slowly move leftwards, as a slow pressure spring is connected between the right end of the rack 16 and the outer side wall of the box body 5, the pressure spring is stretched, meanwhile, as the upper end face of the rack 16 is provided with the ratchet 18, the box body 5 is inserted with a first pin 19 capable of moving upwards and downwards, and the first pin, the rack 16 is moved only to the left and therefore the rack 16 is moved stepwise to the left.
When the rack 16 moves leftwards to be in contact with the gear ring 14 on the left side, the rack 16 can push the gear ring 14 to rotate, and after the gear ring 14 rotates, the two shift levers 12 can move inwards and outwards in a reciprocating mode under the action of the groove; meanwhile, the moving directions of the two shift levers 12 are opposite; for convenience of description, the angle between the two stop levers 15 is 60 °, and referring to fig. 6, before the ring gear 14 rotates; the front stop lever 15 starts the function of stopping the shift lever 12; when the gear ring 14 rotates counterclockwise, the front stop lever 15 will be outward (enter the groove) first, and the rear stop lever 15 will be inward (disengage the groove) at the same time; after the action is finished, the valve rod 9 rotates clockwise by 30 degrees under the action of the torsion spring 11 and stops rotating (the stop lever 15 at the rear side starts to stop at the moment); then the gear ring 14 continues to rotate, the stop lever 15 at the front side faces inwards, and the shift lever 12 at the rear side faces outwards; the valve rod 9 continues to rotate clockwise by 60 degrees and stops rotating (the stop lever 15 on the front side starts the blocking function again); by rotating the front stop lever 15 by 90 ° in several times, a smart "borrowing" is achieved, and after the valve is closed by 30 °, the rack 16 still has a certain driving force.
After the valve rod 9 rotates ninety degrees, the ball valve 3 is closed at the moment, so that automatic closing is realized, and as the rack 16 moves in a stepping mode, the stepping speed and frequency are adjustable, the initial position of the rack 16 is also adjustable, namely the stroke of the rack 16 is adjustable, so that the delayed triggering effect is realized, and the valve of the ball valve 3 can be delayed and automatically closed.
After spraying one section, the precast beam need spray once more, need to lead to water once more this moment, only need upwards pull out first pin 19 this moment, rack 16 can reset right under the effect of the pressure spring of connection between rack 16 right-hand member and box 5 lateral wall this moment, make rack 16 resume initial position, rack 16 also can drive ring gear 14 and rotate along with the pointer simultaneously, this moment, valve rod 9 can twist ninety degrees once more (concrete principle is same with above, this process is the reverse process of last process), make ball valve 3 opened here, whole device all resumes the state before the use simultaneously.
According to the invention, the impeller 7 is arranged, the torque is transmitted through the rotating shaft 6, and then the torque is transmitted to the torsion spring 11 through the gear set, so that the torsion spring 11 can be firstly 'forced up' when being used each time, then the rotating shaft 6 is separated from the driving wheel 8, the rotating shaft 6 is independently rotated, and meanwhile, the step motion of the rack 16 is realized by utilizing the meshing action of the incomplete gear 17 and the rack 16, so that the purpose of time delay is achieved, the spraying time can be adjusted by adjusting the initial position of the rack 16, and the reduction ratio of the planetary gear system is reasonably adjusted, and experiments prove that the adjusting range of the time delay can be about 1 to 20 minutes.
According to the invention, by arranging the gear ring 14, the stop lever 15, the shift lever 12 and the groove and simultaneously utilizing the driving of the rack 16, when the gear ring 14 rotates, the two stop levers 15 can alternately stop the shift lever 12, and the 90-degree separation is carried out in two steps, so that the stop lever 15 is borrowed, and the over-rotation of the valve rod 9 caused by the excessively low moving speed of the stop lever 15 is avoided; after the valve rod 9 rotates 90 degrees each time, the states of the stop lever 15 and the deflector rod 12 are initial states; then, the characteristics of the ball valve 3 are matched (the opening and closing state is changed by rotating 90 degrees), and the opening and closing of the valve are skillfully controlled.
The automatic spraying device is convenient to operate, the whole device can automatically run only by pulling the rack when spraying is needed, a circuit does not need to be arranged, safety, reliability, convenience and rapidness are realized, energy is stored by utilizing a mechanical structure and automatic closing is realized, water is saved, and the effect of fully spraying is achieved.
