Description

Power supply unit that water supply network check out test set used

Technical Field

The utility model relates to a water supply network check out test set supporting facility technical field, especially a power supply unit that water supply network check out test set used.

Background

In the prior art, no matter in municipal tap water or reclaimed water supply networks, data such as water pressure and water flow in pipelines need to be mastered, so that relevant control strategies are formulated for water supply departments, or the working modes of the water supply system are directly controlled through received water pressure and water flow data (for example, the received water flow and water pressure in user pipelines are low, the water supply system increases the water supply amount under the action of a control system of the water supply system, for example, the received water flow and water pressure in user pipelines are high, and the water supply system reduces the water supply amount under the action of the control system of the water supply system) to provide data support. Furthermore, some existing urban pipe networks have leakage phenomena due to poor management, aging and other reasons, the most serious production and marketing difference reaches more than 30%, and the state requires that the production and marketing difference is controlled within 10% in 2020, so that the phenomena of leakage, pipe explosion and the like must be checked by means of detection means (detecting water pressure and water flow data in pipelines as well), and warning or early warning analysis is carried out in advance after problems occur, so that the problems of secondary disasters caused by the fact that a large amount of water resources of the pipe networks are wasted due to the fact that rush repair treatment is not found or is not found in time are reduced, and the soil around the pipes is scoured (most of subway pipelines and pavement collapse in cities are caused by leakage of the pipe networks).

In practical application, in order to obtain water pressure and water flow data in a pipeline, water pressure and water flow detection equipment and the like are installed at the side end of the pipeline needing a detection point (the pipeline is located in a pipeline well which is provided with a drainage facility to prevent the pipeline well from being submerged due to rainwater, water leakage and the like), and the detected data of the water pressure and water flow detection equipment and the like are transmitted to a water supply management department through a 4G or wireless transmission module in real time. In order to ensure normal operation of the water pressure and water flow detection equipment and effective transmission of data after detection of the water pressure and water flow detection equipment, power supply for the 4G or wireless transmission module, the water pressure and water flow detection equipment (hereinafter referred to as electric equipment for short) and the like is a premise for ensuring normal operation of the equipment. The existing power supply modes for electric equipment and the like are limited by the distribution of pipe wells, particularly, the existing pipe wells are distributed in the center of a road, and the solar energy or wind energy cannot be adopted to provide power for the related electric equipment, so that two power supply modes are generally adopted, one mode is directly adopting 220V mains supply power, and the other mode is adopting a storage battery for power supply. The construction difficulty is increased due to the fact that power supply wires need to be laid when a 220V power supply is adopted for power supply, particularly when a pipeline is far away from a 220V power line, inconvenience is brought to construction, construction cost is increased, and due to the fact that the wires are connected, if a power transmission line is erected on the ground, not only is the coordination of the surrounding environment affected, but also certain influence is brought to ordinary safety management; if adopt independent battery power supply, need charge or change the battery for the battery at an interval for a certain time again in the use, because every terminal signal and consumption difference, lead to the battery power consumption different, the management must become a normality in the maintenance of patrolling and examining of daily battery like this, can bring very big inconvenience for management at ordinary times, greatly increased use and administrative cost, when managers forget to charge because of various reasons very much, can lead to unable normal work such as consumer, and then influence water supply system's normal detection work.

In order to guarantee the power utilization of the electric equipment and free maintenance, the mode of installing the water flow generator in the pipeline for generating power can be adopted to supply power for the electric equipment theoretically, when water flows, the water flow drives the turbine blades of the hydroelectric generator to rotate, and then the generator generates power to supply power for the electric equipment. However, in actual conditions, the speed of water flow in the pipeline is not high, the water flow has no pressure difference, and the acting force acting on the turbine blades of the water flow generator is extremely small, that is, the current and the voltage generated by the hydroelectric generator are extremely weak (generally, only 10 mA exists, the water flow is too low, or even no electric energy is generated), so that the water flow generator cannot effectively supply power to the electric equipment at all, and further the electric equipment cannot normally work, and the management of a water supply department is influenced. Based on the above, in the field of water supply, it is necessary to provide a power supply device capable of continuously supplying and charging power, and capable of ensuring that relevant equipment can transmit real-time data to the background of the water supply department continuously for 24 hours all day.

As shown in figures 1, 2 and 3, the novel water supply device is used on a municipal water supply backbone network and reclaimed water supply water, and effective power supply for 4G or wireless transmission modules, water pressure and water flow detection equipment and the like is guaranteed. The lithium secondary battery G is fully charged before use. After the power output by the lithium storage battery G enters the two ends of the power input of the low-voltage detection circuit, the remote control circuit, the foot voltage detection circuit and the electric equipment A1, the low-voltage detection circuit, the remote control circuit, the foot voltage detection circuit and the electric equipment A1 are in an electrified working state. In the low voltage detection circuit: when the voltage of the lithium storage battery G is normally above 6V at ordinary times, the voltage of a pin 3 entering the three-terminal voltage integrated detection circuit A2 is reduced and limited through the adjustable resistor RP at the moment, and the voltage is higher than the internal 4.75V threshold voltage of the three-terminal voltage integrated detection circuit A2, so that under the action of an internal circuit of the three-terminal voltage integrated detection circuit A2, a pin 1 outputs a high level, a base of the PNP triode Q1 is not provided with a proper low level and is in a cut-off state, a pin 3 of the follow-up power time controller module A3 cannot be input with a high level signal, then the relays J1 and J3 cannot be electrified to attract, a valve core of the electric ball valve M cannot be electrified to be closed, and the.

In fig. 1, 2 and 3, in the low voltage detection circuit and the remote control circuit: when the voltage of the lithium storage battery G is below 6V and about 5.9V (the lithium storage battery G is in a loaded state, the voltage of the loaded lithium storage battery is above 6V after the lithium storage battery is fully charged, and the storage capacity of the lithium storage battery G is generally reduced to three-quarter when the voltage of the lithium storage battery G is about 5.9V), the storage capacity of the lithium storage battery G is reduced to a certain range, at the moment, the voltage of the 3 pin of the three-terminal voltage integrated detection circuit A2 is reduced and limited by the adjustable resistor RP, and is lower than the internal 4.75V threshold voltage of the three-terminal voltage integrated detection circuit A2, so under the action of the internal circuit of the three-terminal voltage integrated detection circuit A2, the 1 pin stops outputting high level and is converted into outputting low level, the low level is reduced in voltage and limited in current through a resistor R1 and then enters the base electrode of a PNP triode Q1, the base electrode of the PNP triode Q1 obtains proper bias current conduction, and the collector outputs high level and enters the 3 pins of a power supply time controller module A3. In actual use, a user can also actively control the opening of the drainage ball valve through the remote control circuit at the far end according to needs to enable the water flow generator to generate electricity, and further electricity utilization of electric equipment is effectively guaranteed (for example, knowing that a pipe network is about to cut off water, and a subsequent water flow generator cannot generate electricity, in order to guarantee the electricity storage performance of a storage battery, the user can actively charge the storage battery at the far end in advance, and guarantee that the whole electric equipment can normally work after water supply is resumed after a period of time after water cut off, and since the electric equipment is continuously in the electricity utilization state after water cut off, the storage battery voltage is possibly too low to control the opening of the electromagnetic ball valve through the low-voltage detection circuit after water supply is resumed, and further the water flow generator cannot generate electricity. In operation, after a user sends a closing wireless command through a mobile phone interface by using the existing mature mobile phone remote control technology, the 3 feet of the finished product A5 of the mobile phone remote controller can output a high level to enter the 3 feet of the power time controller module A3 (after the 3 feet of the finished product A5 of the mobile phone remote controller output a high level to enter the 3 feet of the power time controller module A3 each time, the user sends an open-circuit wireless command through the mobile phone interface by using the existing mature mobile phone remote control technology, the 3 feet of the finished product A5 of the mobile phone remote controller can stop outputting a high level to enter the 3 feet of the power time controller module A3, and preparation is made for next control). In practical situations, no matter the voltage of the lithium battery G is reduced, the 3-pin of the power time controller module A3 inputs high level, or the user inputs high level through the 3-pin of the mobile phone controlled power time controller module A3 at a remote end, since the 2-pin and 4-pin of the power time controller module A3 are connected to the negative electrode of the lithium battery G, the power time controller module A3 will simultaneously input the positive and negative power trigger signals (the 1-pin of the power time controller module A3 is connected to the positive electrode of the lithium battery G), so that the 9-pin of the power time controller module A3 will output 5 minutes of high level to the negative power input ends of the relays J1 and J3 (the negative power input end and the negative control power input end of the relay J1, the negative power input end of the lithium battery G, and the power time controller module A3 will be under the action of its internal circuit and the 9, The power supply input end of the negative electrode of the relay J3 is connected with the negative electrode of the lithium storage battery G), so that the relay J1 is electrified to attract the two control power supply input ends and the two normally open contact ends of the relay J1 to be closed respectively, and the relay J3 is electrified to attract the control power supply input end and the normally closed contact end of the relay J3 to be opened; because two normally open contact ends of the relay J1 are respectively connected with the positive and negative pole power input ends of the electric ball valve M through leads, the electric ball valve M can be electrically operated within 5 minutes to drive the valve core to rotate clockwise to be in a fully open state (under the actual condition, the valve core of the electric ball valve M can be fully opened within about 5 seconds); when the time is about 5 seconds, a power output shaft of a motor speed reducing mechanism of the electric ball valve drives the transverse plate 41 to rotate rightwards to a stop point, the rear side end of the transverse plate 41 just presses the first microswitch S1 button, two normally closed contacts in the microswitch button S1 are opened, because one normally open contact end of the relay J1 is connected with one end of the microswitch S1, the other end of the microswitch S1 is connected with the positive power input end of the electric ball valve M, the electric ball valve M can lose power and stop working after the valve core of the electric ball valve M is fully opened at the moment, and the electric ball valve M is prevented from rotating rightwards too much to cause the electric ball valve M to stop working normally; when the valve core of the electric ball valve M is opened within 5 minutes, water in the water supply pipeline 8 flows out from the water outlet pipe 81 (with the pipe inner diameter of about 0.5 cm), the water inlet end of the water flow generator FD and the water outlet end of the water flow generator FD, and flows out through drainage facilities of an underground well, and a large water pressure flows into the water flow generator FD to drive the turbine blades thereof to rotate, so that the water flow generator FD generates electric energy to enter the two

ends

1 and 2 of the power input of the ac-dc power supply module a4, and the ac-dc power supply module a4 converts the input ac power supply into a stable 7.2V dc power supply to charge the lithium storage battery G under the action of the internal circuit thereof (generally, the power is fully charged for 5 minutes), and simultaneously supplies power to the electric equipment a1, the low-voltage detection circuit, the foot-voltage detection circuit and the mobile phone remote controller product a5 (the working voltage of the electric equipment a1, the 7.2V power supply does not have any impact on its operation).

As shown in fig. 1, 2 and 3, in the present invention, after 5 minutes, the pin 9 of the power time controller module a3 stops outputting the high level of the clock and enters the positive power input terminals of the relays J1 and J3, so that the relay J1 loses power and no longer attracts two control power input terminals and two normally open contact terminals of the relay J1 to open circuits respectively, and the relay J3 loses power and no longer attracts two control power input terminals and a normally closed contact terminal of the relay J3 to close; because the two normally open contact ends of the relay J1 are respectively connected with the positive and negative pole power input ends of the electric ball valve M through leads, the positive and negative pole power input ends of the electric ball valve M can not be electrified at the moment; since the normally closed contact end of the relay J3 is connected with the 3 pins of the power time controller module A6 (the 1 pin of the power time controller module A6 is connected with the positive pole of the lithium storage battery G), the 2 pins and the 4 pins of the power time controller module A6 are connected with the negative pole of the lithium storage battery G, therefore, at the moment, the power time controller module A6 can simultaneously input a positive and negative power trigger signal, so that under the action of an internal circuit of the power time controller module A6 and 9-pin power output time set by production technicians, the 9 pins of the power time controller module A6 can output a high level for 6 seconds to enter a positive power input end of the relay J2 (the negative power input end and the negative control power input end of the relay J2, and the positive control power input end are respectively connected with the negative and positive poles of the lithium storage battery G), and then the relay J2 is powered on to attract two control power input ends and two normally open contact ends of the relay J2 to be respectively closed; because two normally open contact ends of the relay J2 are respectively connected with the negative and positive power input ends of the electric ball valve M through leads, the electric ball valve M can be used as an internal motor speed reducing mechanism thereof to drive the valve core to rotate anticlockwise to be in a fully closed state within 6 seconds (under the actual condition, the valve core of the electric ball valve M can be fully closed within about 5 seconds); when the time is about 5 seconds, the power output shaft of the motor reducing mechanism of the electric ball valve drives the transverse plate 41 to rotate leftwards to the dead point, the front side end of the transverse plate 41 just presses the button of the second microswitch S2, two normally closed contacts inside the microswitch S2 are opened, because one normally open contact end of the relay J2 is connected with one end of the microswitch S2, the other end of the microswitch S2 is connected with the negative power input end of the electric ball valve M, the valve core of the electric ball valve M is in a fully closed state at the moment, the electric ball valve M can lose power and does not work any more, the electric ball valve M is prevented from rotating leftwards too much to cause the abnormal work of the electric ball valve M, and the preparation is made for the.

As shown in figures 1, 2 and 3, under the action of all the circuits, the novel water flow detection device ensures effective power supply for 4G or wireless transmission modules, water pressure and water flow detection equipment and the like. At ordinary times when this novel lithium battery G voltage normally is in more than 6V, rivers generator does not generate electricity, consumer also can normally work, when lithium battery voltage reduces about 5.9V, the drainage ball valve can be opened automatically to low pressure detection circuitry, produce rivers and act on rivers generator electricity generation, sufficient enough back foot pressure detection circuitry self-closing drainage ball valve of battery voltage, in-service use, the user still can open the drainage ball valve through remote control circuit active control at the distal end as required and make rivers generator electricity generation, and then effectively guaranteed the consumer power consumption. Before the novel adjustable resistance RP is produced, the resistance value of the adjustable resistance RP is required to be determined, the lithium storage battery G is disconnected from a circuit before the determination, then two poles of an external adjustable output voltage direct current power supply are connected to two input ends of a low-voltage detection circuit power supply, the power output end of the adjustable output voltage direct current power supply is adjusted to a position of 5.9V, then an adjusting knob of the adjustable resistance RP is slowly adjusted, the resistance value (about 115K) is adjusted, the adjustment purpose is achieved just after the relay J1 is powered on and attracted, in the subsequent practical use, when the voltage of the lithium storage battery is just lower than 5.9V, the relay J1 is powered on and attracted, and the practical requirement is met; then, the external adjustable output voltage direct current power supply is separated from the circuit, the adjustable resistor RP is disconnected from the circuit, the resistance value of the adjustable resistor RP is measured by using a resistance meter, the measured resistance value is the actual resistance value required by the subsequent production of the adjustable resistor RP, and then the adjustable resistor RP and the lithium storage battery G are connected into the circuit again. It should be noted that after the resistance value of the adjustable resistor RP is determined, the subsequent actual production does not need to determine again, and the resistance value of the adjustable resistor RP is directly adjusted to the required resistance value, or is replaced by a fixed resistor with the same resistance value. Although the power generation can use a certain amount of tap water, the storage battery is charged on site without managers, and the normal work of the electric equipment is guaranteed, so that the cost effectiveness ratio is high. The resistance of the resistor R1 is 4.3K; the model of the PNP triode Q1 is 9012; relays J1, J2, J3 are 6V miniaturised relays; the specification of the adjustable resistor RP is 470K; the microswitches S1, S2 are normally closed contact push button microswitches.
