Description

A kind of digital display intelligent water meter

The utility model discloses a kind of numeral and show intellectual water meter, is to adopt huge Magnetic Sensor to gather water-flow signal, the Based Intelligent Control water meter of low-power consumption electrically operated valve.

Current, the development of China's intellectual water meter industry just is being full of present flourish vital, face simultaneously strong market challenges again, no matter the mode that existing intellectual water meter research and development and manufacturing enterprise unit are adopted is monoblock type table or split type table, all exist volume bigger, the deficiency that weight is heavier, and the cost of intellectual water meter can be in any more always, be 5 to 7 times of general normal domestic water meter, in the water meter of China is promoted at present, this cost is beyond affordability, thus intellectual water meter to apply resistance big, benefit is not obvious, using water wisely, the realization water is scientific, and the process of standardization and network management is slowed down greatly.

The purpose of this utility model is: by existing Chinese intellectual water meter being accepted and believed the improvement of technology, the integration of intellectual water meter technology, it is little to design a kind of volume, in light weight, the total Based Intelligent Control water meter that shows, reduce the intellectual water meter cost, thereby promote the development of intellectual water meter cause, advance the process of intellectual water meter application.

Technical application scheme of the present utility model is: with original water meter contraction in length to existing international length; With traditional multithread bundle movement volume-diminished; Adopt huge Magnetic Sensor and fluidics and magnetic bearing to reduce the initiating flow of water meter; Valve is assemblied in realization valve control and management in the water gauge chamber; Battery is used instead to dry cell and interchangeable, made that the use of water meter is more reliable.

The utility model is summed up, is integrated existing intellectual water meter technology, and novel in design original, compact conformation is reliable, and volume is little, and is in light weight, and the precision height does not have mechanical character wheel and shows that outward appearance is small and exquisite attractive in appearance, has the very strong market competitiveness.

Now the utility model is described in detail in conjunction with example:

Fig. 1 the utility model structural representation;

As shown in Figure 1: watchcase (1) is gone up valve seat (2) is installed; valve seat (2) is fixed on the watchcase (1) by screw (3); pad (4) and O-ring seals (5) make sealing between valve seat (2) and the watchcase (1); valve seat (2) is gone up water inlet valve (6) is installed; be installed into mouth of a river mold insert (7) on the watchcase (1); between water inlet valve (6) and the valve seat (2) preloading spring (8) is installed; the interior mounting ball valve of valve seat (2) (9); axle (10) one ends connect ball valve (9); the other end is fixedlyed connected with sector gear (11); sector gear (11) and sector gear (12) engagement; sector gear (12) is fixedlyed connected with axle (13); movement (14) is installed on the valve seat; drive the mouth of a river around the movement impeller box into; the mouth of a river is left in the bottom of impeller box; magnetic bearing (36) is installed in the movement (14); fluid drives wheel (37) is suspended on the magnetic bearing (36); middle cover (15) is movement (14) and axle (13) fixedly; screw (16) is fixedlyed connected middle cover (15) with watchcase (1); in O-ring seals (17); (18); (19) effect realizes the sealing in table chamber down; gear case (20) is fixed on the middle cover (15); establish torsion spring (21) on its output shaft (22); output shaft (22) connects with axle (13); gear case (20) is gone up battery case (26) is installed; the built-in 4 joint 1.5V dry cells (27) of battery case (26); power-off protector (35) is installed in the battery case bottom; master control borad (29) is installed in the electrical equipment box (28); card reading antennas (30) and Card Reader switch (31); middle cover (15) is gone up the antimagnetic dried switch (32) of scratching is installed; fixing upper casing (33), upper casing (33) is gone up fixedly transparency window (34).

The course of work of this table is a sample: the user is after sell water station and purchase water, be stuck in table and go up card-reading zone and gently shake with selling water, at this moment Card Reader switch tongue tube (31) is connected, master control borad (29) is waken up to finish by card reading antennas and purchases in the card in the water yield data input controller, motor gearbox (20) work, drive axle (22) rotation, torsion spring (21) accumulation of energy simultaneously, axle (22) drives axle (13) and rotates, open ball valve (9) by sector gear (12) and sector gear (11) and supply water, when water consumption was little, water inlet valve (6) was under the pretension of spring (8), be pressed on the water inlet mold insert (7), water can only pass through jet pipe (24) and flow into movement (14), because sectional area is little, hydraulic pressure increases, form jet impulse movement impeller, the metering of realization low discharge: when the tail water flow was big, the pressure reduction on water inlet valve (6) both sides became big, surpasses the acting force of preloading spring (8), inlet valve (7) is open, and water meter enters normal duty; Adopt magnetic bearing (36), fluid drives wheel (37) is suspended on the magnetic bearing (36), there are not the machinery wearing and tearing between fluid drives wheel (37) and the magnetic bearing (36), the initiating flow reduces, long service life, the measuring accuracy height, huge Magnetic Sensor (23) is gathered the water-flow signal of movement (14), change it into electric signal and import out master control borad (29), count and successively decrease.When purchasing water number in the table when being decremented to zero, master control borad sends and closes the valve instruction, motor gearbox (20) backward rotation, and ball valve is closed, and cuts off current and stops to supply water.

When the energy of battery (27) used up, master control borad (29) detected voltage low signal, sent to close the valve instruction motor gearbox (20) counter-rotating closing valve; When the user changes battery, pull out battery case (26), power-off protector (35) sends power-off signal, and master control borad (29) sends and closes the valve instruction, motor gearbox (20) counter-rotating closing valve.

When external magnetic field was disturbed, the thief-proof switch that is distributed on the middle cover (15) preferentially detected external magnetic field, and the extraneous interference situation is posted a letter to master control borad (29), and master control borad (29) sends and closes the valve instruction, motor gearbox (20) counter-rotating, valve-off.
