In an embodiment of the self-control cutoff device for the burst of the water pipe of the main trunk line, the elastic force of the clutch spring (9) is smaller than the pressure of normal running water in the water pipe of the main trunk line and is larger than the pressure of abnormal running water after the burst of the water pipe of the main trunk line.
According to the automatic control cutoff device for the burst of the water pipe of the main pipeline, the pressure of abnormal running water after the burst of the water pipe of the main pipeline is reduced, the clutch spring (9) drives the clutch piston (8) to sink, and the third speed reduction driving wheel (6) is connected with the clutch gear (7) and drives the clutch gear (7) to rotate.
According to the automatic control cut-off device for the burst of the water pipe of the main trunk pipe, after the water pipe of the main trunk pipe bursts, the clutch gear (7) drives the working gear (11), the working gear (11) drives the working cam (12) to rotate through the working shaft (16), the convex surface of the working cam (12) leaves the top end bearing (13) of the cam, and the working water valve (15) fixed behind the top end bearing (13) of the cam automatically closes the water pipe of the main trunk pipe under the thrust of the spring (17).
The embodiment I of the invention relates to a main trunk water pipe burst self-control flow-cutting device, which has the working principle that: the water flow is changed greatly after the water pipe bursts. When the main road is not burst, the pressure intensity in the water pipe is about 0.3 MPa. When some part of the main road bursts, the water flow in the water pipe is increased rapidly, and the pressure is reduced rapidly and is close to 0.
The main principle of the embodiment is as follows:
1. the impeller is pushed by the flowing of tap water to provide power for closing the valve;
2. the reduction gear is used as an intermediary device for transmitting and increasing power;
3. controlling the closing of the working valve by utilizing the displacement of the cam;
4. the clutch working state of the clutch gear, the driving wheel and the working gear is controlled by the burst of the main water pipe and the change of water pressure in the pipe when the main water pipe is intact.
Example one principle analysis is as follows:
1. when the water works normally supply water and the water pipe of the main pipeline is burst, the working water valve is opened because the working valve is pressed by the cam and the bearing at the top end of the cam, and the water pipe of the main pipeline normally supplies water.
2. At the moment, on one hand, tap water enters from the water inlet to push the impeller to rotate, and the driving wheel drives the speed-reducing and force-increasing intermediate driving wheel to rotate so as to provide power to the rear. On the other hand, because the main pipeline still has enough water pressure allowance, the pressure can overcome the elasticity of the clutch spring and the gravity of the clutch piston, the clutch wheel and the like, and the clutch piston is upwards propped against, so that the clutch wheel moves upwards to leave the speed reduction transmission wheel, the power in front cannot be transmitted to the working gear and the cam, the working cam cannot rotate to generate displacement, the cam and the bearing at the top end of the cam are propped against the water valve to open, the pipeline is kept smooth, and water is normally supplied.
3. If the water pipe of the main channel bursts, the flow in the water pipe increases sharply, the impeller rotates in an accelerated way, and sufficient power is provided backwards through deceleration and reinforcement. On the other hand, the water pressure in the pipe is greatly reduced, the clutch piston falls under the action of the elastic force of the spring and the gravity of the piston and the clutch wheel, the clutch wheel moves downwards to be meshed with the speed reduction transmission wheel, so that the power in front is transmitted to the working gear and the cam, the working cam rotates to generate displacement, the cam and a bearing at the top end of the cam press against the water valve to be released, the working valve returns to the original position under the action of the spring of the working valve to close the valve, and the automatic cut.
4. When the burst pipeline is repaired, the maintenance personnel rotate the manual reset rotary handle again, the bearing at the top end of the cam is jacked and opened, the working valve is opened again, and the smooth pipeline and the normal water supply are recovered.
5. When water is cut off, the water pressure and the water flow are 0, although the clutch is decompressed, the clutch wheel moves downwards to be meshed with the speed reduction transmission wheel, but the impeller cannot provide power because of no water flow pushing, the working cam cannot rotate to generate displacement, the working water valve is pressed to open, and the pipeline is kept smooth. When the tap water is returned to water supply, the impeller can rotate to provide power, but the pressure in the pipe rises rapidly to make the clutch wheel move upwards to separate from the speed reduction driving wheel, the power in front cannot be transmitted to the working gear and the cam, the bearing at the top end of the cam is pressed to open, the pipeline is kept smooth, and the user can use the water normally.
Embodiment two the invention relates to a self-control cut-off device for burst of a water pipe of a main trunk, wherein an impeller (2) is arranged in the front part of the water pipe (1) of the main trunk, an impeller shaft (23) is arranged on the impeller (2), a plurality of layers of main shaft oil seals (21) are arranged on the impeller shaft (23), a impeller box sealing cover (22) is fixed at the top of each layer of main shaft oil seal (21), a connector (28) of a fixed shaft at the top of the impeller shaft (23) is connected with a small-sized generator (24), a pointer type water pressure switch (25) is arranged in the middle of the water pipe (1) of the main trunk, a common manual reset electromagnetic valve (26) is arranged at the rear part of the water pipe (1) of the main trunk, an electromagnetic valve manual reset handle (27) is arranged at the top end of the common manual reset electromagnetic valve (26), a simulated water pipe burst gap (18) is arranged at the outlet of the water pipe (1, a user valve (19) is installed on a user water pipe (20), and a small generator (24) is electrically connected with a common manual reset electromagnetic valve (26).
In the second embodiment, the automatic control cutoff device for the burst of the water pipe of the main trunk disclosed by the invention automatically controls the water valve to be closed after the burst of the main trunk by applying the principles of power generation and an electromagnetic valve. This is realized by applying the mechatronic principle.
