Abstract

The utility model discloses an automatic control switch of a water pump, comprising a base above which a sealed switch box is arranged, wherein a guide groove is arranged on the side wall of the switch box and internally provided with a guide rod inserted into the base; the bottom end of the guide rod is provided with a float ball, while the top end thereof is provided with a magnet; the switch box is internally provided with a contact switch which is connected with a control power line; the switch box is internally provided with a magnet movable rod capable of pressing the contact switch downand movably connected on the side wall close to the guide groove; and a return spring is connected on the magnet movable rod. In the automatic control switch, the float ball is arranged below the guide rod fixed with the magnet and drives the guide rod to move up and down with the change of water level so as to control the distance between the magnet and the magnet movable rod and cause the magnet movable rod to press or release the contact switch for controlling the opening and closing of the water pump; and the automatic control switch can automatically control the work of the water pump according to water level.

Description

The water pump automatic control switch

Technical field

The utility model relates to a kind of control switch, especially a kind of water pump automatic control switch.

Background technique

At present, water pump is the important tool of transporting water, and its main effect is that water is transported to another zone from a zone.Now water pump control is normally by manually carrying out, when water pump draws water, the regional water level that drawn water can descend, water is transported to another regional water level and keeps rising, after drawdown arrives to a certain degree, water pump just is difficult to water is continued to take away, perhaps after the regional water yield that needs transporting water has met the demands, will not cause waste on the energy if do not stop pump working, more serious is possible cause water pump idle running and water pump is damaged, and the common like this operator of needs are guarding SEA LEVEL VARIATION always.Though some switches according to the water level automatically controlled water pump are also arranged now, the installation conditions restriction of these switches is many, and fabricating cost is higher, is difficult to extensive utilization.

The model utility content:

The purpose of this utility model is: a kind of water pump automatic control switch is provided, and it can be according to the closing and opening of SEA LEVEL VARIATION automatically controlled water pump, effectively energy saving; and protection water pump; and cost of production is low, and applied range is to overcome the deficiencies in the prior art.

The utility model is achieved in that the water pump automatic control switch, comprise base, above base, be provided with the switch box of a sealing, on the sidewall of switch box, be provided with a guide groove, in guide groove, be provided with a guide rod that enters base, bottom at guide rod is provided with ball float, is provided with magnet on the top of guide rod; In switch box, be provided with a contact-making switch, contact-making switch is connected with the control power line, and in switch box, being provided with the magnet motion bar that contact-making switch can be depressed, the magnet motion bar is movably connected near on the sidewall of guide groove, is connected with a return spring on the magnet motion bar.

The control power line passes the bottom of switch box, is provided with seal ring between control power line and switch box.

Owing to adopted technique scheme, compared with prior art, the utility model is installed a ball float below a guide rod that is fixed with magnet, ball float along with driving guide rod, SEA LEVEL VARIATION is moved up and down, thereby the distance between controlling magnet and the magnet motion bar compresses magnet controlling magnet motion bar or unclamps contact-making switch, with the unlatching of control of pump and close, so just do not need manually to guard water pump, can be according to the work of water level situation automatically controlled water pump.Of the present utility model simple in structure, cost of production is low, applied range, and using effect is good.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is an another kind of structural representation of the present utility model.

Embodiment

Embodiment 1 of the present utility model: the structure of water pump automatic control switch as shown in Figure 1, make a base 1 earlier, the switch box 2 of a sealing is installed above base 1, and on the sidewall of switch box 2, fix a guide groove 3, in guide groove 3, place a guide rod 4 that enters base 1, bottom at guide rod 4 connects ball float 5, fixes a magnet 6 on the top of guide rod 4; A contact-making switch 7 is installed in switch box 2, and contact-making switch 7 is connected with control power line 10, and control power line 10 passes the bottom of switch box 2, installs seal ring 11 between control power line 10 and switch box 2; And in switch box 2, flexibly connect a magnet motion bar 8 on the close sidewall of guide groove 3, and on magnet motion bar 8, connect a return spring 9.

Embodiment 2 of the present utility model: the structure of water pump automatic control switch as shown in Figure 2, make a base 1 earlier, the switch box 2 of a sealing is installed above base 1, and on the sidewall of switch box 2, fix a guide groove 3, in guide groove 3, place a guide rod 4 that enters base 1, bottom at guide rod 4 connects ball float 5, fixes a magnet 6 on the top of guide rod 4; A contact-making switch 7 is installed in switch box 2, and contact-making switch 7 is connected with control power line 10, and control power line 10 passes the bottom of switch box 2, installs seal ring 11 between control power line 10 and switch box 2; And in switch box 2, flexibly connect a magnet motion bar 8 on the close sidewall of guide groove 3, and on magnet motion bar 8, connect a return spring 9.

In use, can as required the water pump automatic control switch be made as structure as shown in Figure 1 and Figure 2 respectively, Fig. 1 is the low water level control structure, and Fig. 2 is the high water level control structure, but its working principle is identical.

Low water level control structure: when the also enough pump working of water level, ball float 5 pushes into guide rod 4 guide groove 3 tops under floating function, the magnet 6 on guide rod 4 tops holds magnet motion bar 8, make the termination of magnet motion bar 8 compress contact-making switch 7, water pump control power line 10 is connected the water pump continuous firing; When drawdown; ball float 5 height are along with water level changes; after drawdown arrives to a certain degree; the top of guide rod 4 has moved to the bottom of guide groove 3; magnet 6 is zoomed out with the distance of magnet motion bar 8; magnet 6 has lost the suction to magnet motion bar 8; magnet motion bar 8 is pulled original position under the effect of return spring 9; unclamped contact-making switch 7; water pump control power line 10 is disconnected; water pump quits work, and so just can not make water pump idle running when water level is not enough, has played the effect of protection water pump.

High water level control structure: during in the course of the work original state, magnet 6 holds magnet motion bar 8 and compresses contact-making switch 7, rising gradually along with water level, ball float 5 pushes into guide rod 4 guide groove 3 tops gradually, after the magnet 6 on guide rod 4 tops rises to top above magnet motion bar 8, magnet 6 has lost the suction to magnet motion bar 8, magnet motion bar 8 is pulled original position under the effect of return spring 9, magnet motion bar 8 unclamped contact-making switch 7, water pump control power line 10 is disconnected; When drawdown, ball float 5 height are along with water level changes, after drawdown can hold the position of magnet motion bar 8 to magnet 6, magnet motion bar 8 compresses contact-making switch 7 once more, water pump is worked on, so just can when water level is too high, water pump be worked on, to avoid causing energy waste.
