Abstract
The utility model relates to a kind of novel water level switch.This novel water level switch comprises Weight plate, float plate, moving contact and fixed contact; Described float plate has slip hole, and Weight plate is placed in float plate by slip hole, and forms a moving sets with float plate; Described moving contact is connected on Weight plate; Described fixed contact is connected in float plate; Moving contact faces fixed contact.The potential safety hazard contacted with water when using this device to remove water level switch work.
Description
Art
The utility model relates to a kind of switch, specifically a kind of novel water level switch.
Background technology
At present, the water level switch commercially used is ball float form mostly, sensitive switch and trigger mechanism are installed in ball float housing, the electric wire of float switch is connected with the sensitive switch in ball float housing, during work, ball float housing is placed in water, the electric wire of float switch is fixed on ground one height, ball float housing with this fixing point for fulcrum, with the lifting of water level, change the angle swimming in the ball float housing of the water surface and horizontal plane and produce, when this angle reaches certain angle, trigger mechanism effect in ball float housing, touch inner sensitive switch, the break-make of conversion sensitive switch, thus realize the work of water lev el control.Because the electric wire of float switch is connected with the sensitive switch in ball float housing, the electric wire of float switch often connects 220V high-tension electricity, and ball float housing is placed in water, causes electric wire to enter ball float housing and must ensure sealing, otherwise producing harm, just there is a potential safety hazard in this.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, provides a kind of novel water level switch.
The technical solution adopted in the utility model: this novel water level switch comprises Weight plate, float plate, moving contact and fixed contact; Described float plate has slip hole, and Weight plate is placed in float plate by slip hole, and forms a moving sets with float plate; Described moving contact is connected on Weight plate; Described fixed contact is connected in float plate; Moving contact faces fixed contact.
The beneficial effects of the utility model: the potential safety hazard contacted with water when removing water level switch work.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is the overall structure schematic diagram of a kind of novel water level switch of the utility model.
Embodiment
Fig. 1 represents the overall structure schematic diagram of a kind of novel water level switch of the utility model.Known by figure, this novel water level switch comprises Weight plate 1, float plate 3, moving contact 4 and fixed contact 5; Described float plate 3 has slip hole 2, and Weight plate 1 is placed in float plate 3 by slip hole 2, and forms a moving sets with float plate 3; Described moving contact 4 is connected on Weight plate 1; Described fixed contact 5 is connected in float plate 3; Moving contact 4 faces fixed contact 5.
This novel water level construction of switch is reasonable in design, during work, it is placed in water, can keep afloat because float plate 3 is lighter than water, Weight plate 1 heavily sinks than water, the floatage energy that float plate 3 designs ensures that water level switch can be kept afloat in the presence of water, entirety is not driven to sink by Weight plate 1, Weight plate 1 is towards the bottom, moving contact 4 and fixed contact 5 are all positioned at side waterborne, it is work like this: the break-make between moving contact 4 and fixed contact 5 is as the contact of water lev el control, good with the equipment connection that will control during work, water level switch is placed in water, when there being enough water, as Fig. 1 state, moving contact 4 contacts with fixed contact 5, and work as water level decreasing to a certain extent, the bottom of Weight plate 1 touches ground, be separated between Weight plate 1 and float plate 3, moving contact 4 and fixed contact 5 separated, when there being enough water, moving contact 4 and fixed contact 5 are on-state, state is off when lack of water, play the effect of water level switch, because moving contact 4 and fixed contact 5 are positioned on the water surface always, so safer.
In addition to the implementation, the present invention also has other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of application claims.
