Abstract
The utility model relates to a control device for controlling water pumps used by water tanks. The utility model is composed of the combination of a floating body lifting device which is arranged in a water tank and a contact closing device on a top cover of the water tank. The floating body lifting device comprises a floating body, a vertical direction guideway and a flexible rope, the other end of the rope is connected with the lower end of a supporting rod which is penetrated and sheathed in a cover plate hole, and the sole weight of the floating body is within one third to two third of the buoyancy of the floating body. The contact closing device comprises two elastic elements used as contacts and a support of the elastic elements, and the upper end of the supporting rod is positioned on the middle of the two conductor elastic elements. The utility model can ensure that when the water level in the tank is high, the water pump doesn't work, when the water level is lower than a setting position, the water pump is started to work. The utility model overcomes the situation of frequent start-up of water pumps existing in the prior art and enhances the service life of water pumps.
Description
The utility model relates to the water pump control device, particularly the water tank limit control of water pump.
Now Chinese rural is generally used water tank, promptly water is extracted in the water tank from well with water pump earlier to store.As a rule, this water tank is provided with a limit switch with water pump: then starting mode of pump draws water when the water in the water tank is lower than a certain position, and then water pump quits work when the water in the water tank is higher than this position.There is following defective in this limit switch: can make decline of water table cause starting mode of pump during owing to water and draw water, and therefore each water, the water yield that don't work is how much, all can make water pump that a course of work that starts-stop to be arranged.As frequent water, water pump frequent starting then.Its result has not only wasted the energy, has also influenced the serviceable life of water pump.
The purpose of this utility model is, a kind of water pump automatic switch control device that is used for above-mentioned water tank is provided, make water pump can be in water tank water level open work when low, out of service when water level is high.
The purpose of this utility model is realized by following mode.
The water pump automatic switch control device that is used for water tank described in the utility model, it is characterized in that, it is constituted by the contact opening and closing device that is located at the buoyancy aid jacking gear in the water tank and be arranged on the water tank top cover, described buoyancy aid jacking gear includes a buoyancy aid and can guarantee its guide rail in the vertical direction lifting, be connected with a flexible strand in the upper surface center of buoyancy aid, the other end of this flexible strand is connected with push rod lower end in being set on cover board hole; The described contact opening and closing device that is arranged on the water tank top cover includes two as the metallic elastic spare of contact and the dielectric support that is connected with top cover, the push rod upper end that is connected with flexible strand is positioned at the centre of two elastic components, also is connected with the lead that is connected with external circuit on two metallic elastic spares respectively; The weight of described buoyancy aid is the 1/3-2/3 of its buoyancy.
The water pump automatic switch control device that is used for water tank described in the utility model can guarantee that water pump is in the state of quitting work when the water level in the water tank is in a high position; When water level was lower than desired location, water pump promptly started work.It has overcome the situation of water pump frequent starting in the prior art, has saved the energy, has also improved the serviceable life of water pump.
Be described further below by embodiment and accompanying drawing.
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Among the figure, (1) is two flap elastics that are made of metallic copper that are in contact with one another, and they are bearing in respectively on the base (2) of insulation, and are connected with lead respectively, in order to being connected of circuit.(3) be push rod, this push rod is set in the through hole on the water tank cover plate (7), and its upper end size is less, so that be inserted in two elastic components.Be provided with the step of two large-sizes on push rod, the radial dimension of the step on top is greater than the through-hole diameter on the top cover, with prevent push rod therefrom landing get off.The big step end face of bottom helps the transmission of buoyancy.(4) be flexible strand.(5) be buoyancy aid, its buoyancy in water equals 1/2 (obtaining this value after the counterweight) of its deadweight.(6) be the vertical direction guide rail, it can guarantee that buoyancy aid is in the vertical direction lifting.(8) for being set on stage clip on the push rod, its end contacts with the step surface of push rod, and an end contacts with the tank lid upper surface, and not landing of push rod was got off when its existence can better guaranteed water level decline, and its elastic force is less than the deadweight of buoyancy aid.(9) be the safety screen of contact opening and closing device.
The water pump automatic switch control device that is used for water tank described in the utility model, its course of work is: when water tank is anhydrous, buoyancy aid is positioned at the water tank bottom, flexible strand (4) is straightened and drives push rod (3) downwards, two elastic components (1) are in contact with one another, turning circuit, make starting mode of pump work, along with the continuous rising of water level, buoyancy aid (5) also rises gradually, up to contacting with the push rod lower surface, and promote push rod gradually and be moved upward to and insert in the middle of two elastic components, force both to separate, circuit disconnects, and water pump quits work.When water consumption more after a little while, though buoyancy aid moves down along with decline of water table, flexible strand is not straightened, thus buoyancy aid can not to drive push rod downward, circuit still is in off-state.After water level continued to drop to flexible strand and is straightened, it is downward that buoyancy aid drives push rod, makes two elastic components be in contact with one another turning circuit, and water pump restarts work.In the present embodiment, regulate the wherein length of push rod and flexible strand, can control the setting of the peak level and the lowest water level of water tank effectively, with the needs of the water tank that satisfies different sizes and different request for utilization.
