Abstract
The utility model discloses a machinery automatic water feeding controller, including a power supply circuit, an automatic control circuit, a lever, a water tank, and a floating ball. The automatic control circuit includes a fuse, a relay, and a main contactor. Any two phases of a three-phase power supply are respectively connected with an input terminal of a transformer (B) and the main contactor (C1) through a secondary fuse (RD2). A loop of the main contactor (C1) is in series connection with a first normally open contact (C21) of the relay. The output terminal of the transformer (B) is in series connection with a second normally open contact (C22) of the relay, a stop touch switch (TA) and the relay (C2) through a fuse (RD3). A start touch switch (QA) is in parallel connection with both ends of the second normally open contact (C22) of the relay. The machinery automatic water feeding controller is simple in circuit, eliminates faults induced by bad electronic components, and improves safety performance.
Description
Technical field
The utility model relates to automation field, relates in particular to a kind of mechanical automatic water-feeding controller.
Background technology
In daily life, the anhydrous phenomenon of water tank spilling water and water tank often occurs, wasted a large amount of hydroelectric resources, so the automatic control of cistern water level becomes inevitable.The electronic component that automatic water-feeding controller in the market uses is more, easy initiating failure, and the while circuit is more complicated also, and manufacturing cost is higher, is difficult for promoting.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, and a kind of mechanical automatic water-feeding controller is provided.
The technical solution adopted in the utility model is: a kind of mechanical automatic water-feeding controller, comprise power circuit, automatic control circuit, lever, water tank, ball float, described power circuit comprises three-phase supply master switch DK, total insurance RD1, main contactor C1 and pump motor M, described lever 1 one ends have been positioned at travelling contact type switch QA, stop between the touch switch TA, the other end is connected with ball float 2 and is arranged in water tank 3, described automatic control circuit comprises insurance, relay, main contactor, any two-phase of described three-phase supply by secondary insurance RD2 respectively with transformer B input end, main contactor C1 connects, connect with the first normally opened contact C21 of relay in described main contactor C1 loop, the output terminal of described transformer B is by the second normally opened contact C22 of insurance RD3 and relay, stop touch switch TA, relay C2 series connection, described travelling contact type switch QA is connected in parallel on the relay second normally opened contact C22 two ends.
The beneficial effects of the utility model are: circuit structure is simple, except the several elements of transformer, relay, contactor that main control loop is used, do not use other electronic component, got rid of the bad fault that causes because of electronic component, improved the reliability of automatic water-feeding controller, owing to use transformer to isolate in the circuit, also improved the security performance of automatic water-feeding controller simultaneously.
Description of drawings
Fig. 1 is circuit diagram of the present utility model.
DK is battery main switch, and RD1 is that power supply always insures, and C1 is main contactor, and M is water pump, and RD2 is the secondary circuit insurance, B is transformer, and RD3 is the transformer secondary output insurance, and C2 is relay, and QA has been the travelling contact type switch, TA is for stopping the touch switch, and 1 is lever, and 2 is ball float, and 3 is water tank.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of mechanical automatic water-feeding controller, comprise power circuit, automatic control circuit, lever, water tank, ball float, described power circuit comprises three-phase supply master switch DK, total insurance RD1, main contactor C1 and pump motor M, described lever 1 one ends have been positioned at travelling contact type switch QA, stop between the touch switch TA, the other end is connected with ball float 2 and is arranged in water tank 3, described automatic control circuit comprises insurance, relay, main contactor, any two-phase of described three-phase supply by secondary insurance RD2 respectively with transformer B input end, main contactor C1 connects, connect with the first normally opened contact C21 of relay in described main contactor C1 loop, the output terminal of described transformer B is by the second normally opened contact C22 of insurance RD3 and relay, stop touch switch TA, relay C2 series connection, described travelling contact type switch QA is connected in parallel on the relay second normally opened contact C22 two ends.
Shown in Fig. 1, principle of work of the present utility model is as follows:
During work, master switch DK closes, when cistern water level dropped to certain water level, lever had been transferred to travelling contact type switch QA, QA conducting, the secondary power of transformer is delivered to the coil of relay C2 through RD3, QA, TA, the closed conducting of C2, the two-phase electricity of main circuit power is delivered to the coil of C1, the closed conducting of C1 through RD2, C2, the three-phase electricity of major loop is delivered to water pump M through main contactor C1, and water pump M begins to go up water.Cistern water level begins to rise, and ball float also begins to rise, and lever begins to leave QA, and QA disconnects, and this moment, the secondary power of transformer continued to deliver to the coil of relay C2 through RD3, C2, TA, and water pump continues to go up water.When cistern water level rose to certain water level, lever was transferred to touch switch TA, and TA disconnects, because TA is serially connected in the C2 wire loop, so relay C2 dead electricity disconnects, contactor C1 also dead electricity disconnects, and water pump stops to go up water.When cistern water level drops to certain water level again, control water pump again and begin to go up water, thereby realized the purpose of water tank automatic loading water.
