Abstract
Description
Technical Field
[0001] This utility model relates to the field of fluid flow technology, and in particular to a flow monitoring device for use in dispersed springs. Background Technology
[0002] Current methods for monitoring spring water flow mainly rely on flow meters or water meters installed on the surface of pipes (32). These devices work by measuring the velocity of the liquid in the pipe through electromagnetic induction and calculating the flow rate by combining the cross-sectional area of the pipe. However, existing monitoring equipment is usually only suitable for full-pipe flow conditions. In non-full-pipe conditions, the monitoring results often fail to accurately reflect the actual flow rate of water in the pipe.
[0003] Furthermore, when springs emerge in the wild in a dispersed rather than concentrated manner, the monitoring results obtained using existing monitoring methods may also be significantly distorted.
[0004] To address the inaccurate flow measurement issues caused by non-full pipe flow monitoring and the dispersed nature of spring water outlets (i.e., dispersed springs), it is necessary to design a novel liquid flow monitoring device. This device should ensure that flow calculations are performed only when the pipe is full and effectively solve the problem of inconvenient collection caused by the dispersed nature of spring water outlets. Utility Model Content

[0010] Preferably, when the current spring water pressure is greater than the standard spring water pressure, the PLC sends a working instruction of opening the switch to the relay.
[0011] When the current spring water pressure is less than the standard spring water pressure, the PLC sends a working instruction of closing the switch to the relay.
[0012] Preferably, the pressure sensor is arranged above the switch at a height h from the top end of the drain pipe, and the standard spring water pressure is P, P = ρgh, wherein ρ is the density of the spring water and g is a constant.
[0013] Preferably, the second baffle is isosceles trapezoidal, and the first baffle and the third baffle are rotationally connected with the legs of the second baffle, respectively.

[0017] Preferably, the first baffle, the second baffle and the third baffle are made of one of PVC, thin steel plate and organic glass.
[0018] The above scheme of the utility model has the following beneficial effects:
[0019] Firstly, the first baffle and the third baffle in the water collector can be rotated, the water collector is arranged downstream of the scattered spring, and the spring water at each exposed point of the scattered spring can be concentrated and collected, so that the problem of insufficient spring water collection is avoided.
[0020] Second, by PLC automatically comparing the size of the standard spring water pressure and the current spring water pressure, ensuring that the drain pipe is in the full pipe state when the switch is turned on each time, the flow of the scattered spring can be accurately monitored, and the measurement error is reduced.
[0021] Third, the flow monitoring device applied to the scattered spring can further include a second water storage tank, which can shunt the first water storage tank when dealing with a scattered spring with a larger flow, thereby avoiding the phenomenon of spring water overflowing the first water storage tank or the water collector.

[0030] In order to make the technical problems, technical solutions and advantages of the present application more clear, the following will be described in detail in combination with the drawings and specific embodiments.
[0031] As Figs. 1-2 shown, the embodiment of the present application provides a flow monitoring device applied to a scattered spring, which is used for monitoring the flow of the scattered spring, and includes a water collector 10, a first water storage tank 20 and a control and monitoring system. The water collector 10 is composed of three plates, which are a first baffle 11, a second baffle 12 and a third baffle 13. The head end of the second baffle 12 is rotationally connected with the tail end of the first baffle 11, the tail end of the second baffle 12 is connected with the head end of the third baffle 13, and the third baffle 13 and the first baffle 11 form a water inlet at the end away from the second baffle 12. The size of the water inlet can be changed by changing the included angle between the first baffle 11 and the second baffle 12 and the included angle between the second baffle 12 and the third baffle 13.
[0032] The first water storage tank 20 comprises a tank body 21, a water inlet pipe 22 and a water outlet pipe 23. The tank body 21 is a cavity. The water inlet pipe 22 is arranged above the tank body 21 and communicates with the cavity. The water inlet pipe 22 also communicates with the water collector 10. The water outlet pipe 23 is arranged below the tank body 21 and communicates with the cavity. The water outlet pipe 23 is provided with a switch 24. The switch 24 is opened or closed to make the spring water flow out of the water outlet pipe 23 or be stored in the water outlet pipe 23. Preferably, the water inlet pipe 22 of the first water storage tank 20 is connected to the second baffle 12.
[0033] The control and monitoring system comprises a PLC, a pressure sensor 31, a water meter 32 and a relay. The pressure sensor 31 is arranged in the water outlet pipe 23 and is used to obtain the current spring water pressure at the installation position of the pressure sensor 31. The water meter 32 is arranged in the water outlet pipe 23 and is used to measure the flow of the spring water in the water outlet pipe 23. The relay is signal connected with the switch 24 to control the opening and closing of the switch 24.
[0034] The standard spring water pressure is pre-stored in the PLC. The standard spring water pressure is the spring water pressure at the installation position of the pressure sensor 31 when the water outlet pipe 23 is full. In use, the pressure sensor 31 sends a signal to the PLC. The signal comprises the spring water pressure at the current time (i.e. the current spring water pressure) at the installation position of the pressure sensor 31. The PLC compares the current spring water pressure with the standard spring water pressure pre-stored in the PLC to determine whether the water outlet pipe 23 is full. The PLC sends a working instruction to the relay to open or close the switch 24 based on the result of whether the water outlet pipe 23 is full. Meanwhile, the PLC also records the time when the switch 24 is opened and closed.
[0035] Specifically, when the current spring water pressure is greater than the standard spring water pressure, the PLC determines that the water outlet pipe 23 has reached the standard of being full. The PLC sends a working instruction to the relay to open the switch 24. When the current spring water pressure is less than the standard spring water pressure, the PLC determines that the water outlet pipe 23 has not reached the standard of being full. The PLC sends a working instruction to the relay to close the switch 24. The water meter 32 records the flow of the water outlet pipe 23 from when the switch 24 is opened to when the switch 24 is closed and feeds back to the PLC.
[0036] Preferably, the switch 24 is in a normally closed state. The PLC also records the time duration of the switch 24 from being opened to being closed in a cycle.
[0037] In some embodiments of the present application, the pressure sensor 31 is installed in the drain pipe 23, and the height of the pressure sensor 31 from the top end of the drain pipe 23 is h, when the drain pipe 23 is full (i.e. the liquid level in the drain pipe 23 is not lower than the top end of the drain pipe 23), at this time the spring pressure at the position of the pressure sensor 31 is P, P = ρgh, wherein ρ is the density of the spring, g is a constant. At this time, the spring pressure at the position of the pressure sensor 31 is the standard spring pressure.
[0038] In some embodiments of the present application, the second baffle 12 is in the shape of an isosceles trapezoid, and the first baffle 11 and the third baffle 13 are respectively connected with the leg 12a of the second baffle 12. Preferably, the connection between the first baffle 11 and the second baffle 12, and the connection between the second baffle 12 and the third baffle 13 are through a diagonal hinge, and the rotation axis of the diagonal hinge is parallel to the leg 12a, so as to ensure that the first baffle 11 and the third baffle 13 can rotate relative to the second baffle 12 to change the size of the water inlet.
[0039] In some embodiments of the present application, in order to cope with the excessive flow of the scattered spring, which exceeds the water storage capacity of the first water storage tank 20, the flow monitoring device applied to the scattered spring further comprises a second water storage tank 40, the structure of the second water storage tank 40 is the same as that of the first water storage tank 20, and the second water storage tank 40 is provided with at least one, and the water inlet pipe of the second water storage tank 40 is communicated with the upper middle part of the first water storage tank 20, so as to realize the shunt of the first water storage tank 20.
[0040] The PLC records the data of the first water storage tank 20 and the second water storage tank 40 respectively.
[0041] Preferably, the first baffle 11, the second baffle 12 and the third baffle 13 are made of one of PVC, thin steel plate and organic glass, so as to ensure that the first baffle 11, the second baffle 12 and the third baffle 13 are not easily damaged.
[0042] In the use of the present application, according to the size of the scattered spring exposure point, the water inlet is opened to different sizes, and a groove for accommodating the first water storage tank 20 and the second water storage tank is dug at a position downstream of the scattered spring, then the water collector 10 is inserted into the soil downstream of the scattered spring, and the water inlet is ensured to face the direction of the scattered spring to ensure that the spring water of each exposure point can flow into the water collector 10. The first water storage tank 20 and the second water storage tank 40 are located in the groove, and it is ensured that the spring water in the first water storage tank 20 and the second water storage tank 40 can flow out of the groove, so as to avoid the influence of the measurement of the flow due to the accumulation of water in the groove.
[0043] The above is the preferred embodiment of the present application, it should be pointed out that for the ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, these improvements and refinements should also be considered as the protection scope of the present application.
