Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.

Extract the existing multinomial problem of flue well ponding in order to solve manual operation vacuum pump, the utility model provides a kind of flue well automatic water pumping device for water.

As depicted in figs. 1 and 2, the utility model preferred embodiment mainly comprises submersible pump 4, circuit breaker KM, ball float 3, limit switch TK, time delay relay SJ, main circuit power switch ZK1, control loop power switch ZK2, voltmeter V, ammeter A, electric power mutual-inductor S1.In order clearly to describe the circuit theory of this preferred embodiment, Fig. 2 has also marked multiple electric wires and terminal, for example: L1, L2, L3 are three phase supply ring current line, L11, L12, L13 are main circuit power switch ZK1 lower end three-phase power line, R, S, T are circuit breaker KM upper end three-phase power line tenminal block, U, V, W are circuit breaker KM lower end three-phase power line tenminal block, and PE is current measurement circuit ground terminal.

More specifically, submersible pump M is arranged in flue well ponding 6, for extracting the flue well ponding 6 of flue well 1.

Circuit breaker KM is connected on the power line (power line being connected with tenminal block U, V, W) of submersible pump M, for controlling the operation of submersible pump M and stopping.

Ball float 3 swims in the required water level place of ponding 6, to detect the change of required water level.Limit switch TK is connected with the control end of circuit breaker KM, for controlling the closed and disconnected of circuit breaker KM.Limit switch TK comprises connecting lever 2, and the Point of Strength of ball float 3 can be fixed on the connecting lever 2 of limit switch TK by pulling strings etc.Ball float 3 changes position up and down by the effect of its buoyancy and gravity, and controls whereby the closed and disconnected of limit switch TK contact.After limit switch TK closure, connect circuit breaker KM and start submersible pump M and draw water, water level declines, and ball float 3 is because self gravitation declines and disconnects limit switch TK.

For the control relation between ball float 3 and submersible pump M, can describe in further detail for: in the time that the ponding 6 of flue well reaches required water level, ball float 3 drives limit switch TK closure, and then circuit breaker KM closure, submersible pump M starts, and submersible pump M extracts ponding 6, and water level declines; When the ponding 6 of flue well 1 is during lower than required water level, ball float 3 drives limit switch TK to disconnect, and then circuit breaker KM disconnects, and submersible pump M stops.

Ball float 3 preferably adopts plastic material, and cost is low, corrosion-resistant.

For fear of circuit breaker KM and submersible pump M frequent starting, move, stop, as Fig. 2, this preferred embodiment also comprises time delay relay SJ, it is connected between limit switch TK and circuit breaker KM, with deferred action cut-off breaker KM.In detail, in the time that ball float 3 declines and disconnects limit switch TK due to self gravitation, time delay relay SJ deferred action cut-off breaker KM, thus avoid water level fluctuations to cause circuit breaker KM and submersible pump M frequent movement, and the water level of maintenance ponding 6 is the steady state below 3 at ball float.
