Detailed Description
The utility model is further described below with reference to examples, but not to be construed as being limited thereto, and any number of modifications which can be made by anyone within the scope of the claims are also within the scope of the claims.
Referring to fig. 1-2, the automatic shutoff device for water flow abnormality of the present invention includes a control module 1, a water flow monitoring module 2, a valve 3 and a brake motor 4. The water flow monitoring module 2 and the valve 3 are both installed on a water supply pipe of a house. The water flow monitoring module 2 is used for monitoring water flow in a water supply pipeline; the valve 3 is used to close or open the water supply pipe. The driving end of the brake motor 4 is fixedly connected with the valve rod of the valve 3. The valve 3 can be actuated by the driving action of the brake motor 4, so that the water supply pipe can be opened and closed. The water flow monitoring module 2 is electrically connected with the input end of the control module 1 and used for transmitting the monitored water flow information to the control module. The output end of the control module 1 is electrically connected with the brake motor 4 and used for sending an action signal to the brake motor 4 when the water passing amount of the water supply pipe exceeds a set water amount threshold value. Namely, when the water consumption of the resident exceeds the set water quantity threshold value, the abnormal water consumption of the resident is judged. At the moment, the control module 1 sends an action signal to enable the brake motor 4 to act and drive the valve 3 to cut off the water supply pipe, so that the purpose of stopping water supply when water is abnormal is achieved. The water safety of residents is guaranteed, the waste of water resources is avoided, unnecessary property loss caused by water seepage is avoided, and the water-saving device has very high practicability.
Wherein, the control module 1 can adopt a PLC controller. The working voltage and the output voltage of the PLC both belong to safe voltages, and the safety problem caused by electric leakage can be well avoided. In addition, through the setting of the PLC controller, the resident can set the water quantity threshold value by himself.
The water flow monitoring module 2 is a turbine sensor and can effectively monitor the water flow in the water supply pipe. In addition, the water flow monitoring module 2 may also adopt a flow monitor or other devices having a flow monitoring function.
Preferably, a manual emergency device is mounted on a valve rod of the valve 3, and is used for closing a water supply pipe in time through the manual emergency device when power is off, so that the reliability of the closer is improved.
The manual emergency device of the present embodiment includes a wheel disc 5, a connecting rod 6, a first bevel gear 7 and a second bevel gear 8. The second bevel gear 8 is fixedly arranged on a valve rod of the valve 3, and the connecting rod 6 is movably arranged on one side of the second bevel gear 8 through a mounting seat 11. Specifically, the mounting seat 11 is provided with an insertion hole matched with the connecting rod 6, and the connecting rod 6 is movably inserted into the insertion hole. First bevel gear 7 fixed mounting is in the one end of connecting rod 6, and first bevel gear 7 links to each other with the meshing of second bevel gear 8, and rim plate 5 fixed mounting is at the other end of connecting rod 6.
When the valve 3 is manually closed, only the rotary wheel disc 5 is needed to be rotated, the connecting rod 6 drives the two bevel gears to rotate, the valve rod can be driven to rotate, the valve 3 is manually closed, and the operation is simple and convenient.
Preferably, the connecting rod 6 is provided with a separating ring groove 9 and a combining ring groove 10, the outer side of the mounting seat 11 is provided with a mounting block 12, a spring 13 is fixedly mounted below the mounting block 12, a pin 14 is movably inserted in the spring 13, the tail end of the pin 14 is movably inserted in the separating ring groove 9 or the combining ring groove 10, a first positioning pin 15 attached to the surface of the mounting block 12 is inserted in the pin 14 above the mounting block 12, and a second positioning pin 16 attached to the bottom of the spring 13 is inserted in the pin 14 below the spring 13.
The pin 14 is limited by two locating pins, so that the pin can be always positioned in the spring 13. When the pin 14 is inserted into the separation ring groove 9, the two bevel gears are separated. At this time, even if the disk 5 is rotated, the valve 3 cannot be opened manually. When the pin 14 is positioned in the combining ring groove 10, the two bevel gears are meshed, and the valve 3 can be opened and closed manually. By means of the arrangement, the situation that the manual emergency device rotates along with the brake motor 4 can be effectively avoided, and therefore safety risks caused by automatic rotation of the exposed wheel disc 5 are avoided. Such as the risk of being involved in clothes, the wheel disc 5 self-injuring people, etc.
When the pin 14 switches the ring groove, the pin 14 is pulled up to be separated from the ring groove. The connecting rod 6 is then pushed so that the other ring groove is located below the pin 14. And finally, the pin 14 is released and is automatically inserted into the annular groove under the action of the spring 13, so that the operation is simple and convenient.
Preferably, the water flow monitoring module 2 and the valve 3 are both installed on a water supply pipe of a house through a connecting pipe 17, and both ends of the connecting pipe 17 are installed with movable butt nuts 18.
If directly install water flow monitoring module 2 and valve 3 on the delivery pipe, then need set up two incisions on the delivery pipe, be unfavorable for the transformation of pipeline and the maintenance of later stage to be changed. Therefore, this embodiment has proposed to install water flow monitoring module 2 and valve 3 on connecting pipe 17, through activity butt joint nut 18 directly with connecting pipe 17 install on the delivery pipe can, improved the convenience of operation.
Preferably, the connection pipe 17 is a hot-dip galvanized pipe or a stainless steel pipe, which can effectively prolong the service life of the pipe.
The working principle of the utility model is as follows: the closer is installed on the water supply pipe, and after the closer starts working, the turbine sensor monitors the water supply amount in the water supply pipe in real time, and transmits water amount information to the PLC controller. The PLC counts the total water amount, and sends an action signal to the brake motor 4 to make the brake motor act when the total water amount exceeds a set water amount threshold value. The brake motor 4 drives the valve 3 to rotate, so that the water supply pipe is closed, and the water supply is stopped in time when the water consumption of residents is abnormal.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various changes and modifications without departing from the structure of the utility model, which will not affect the effect of the utility model and the practicability of the patent.
