Abstract
The invention relates to a ground water sensor, which comprises a housing and an induction piece ; the housing takes the shape of 'JI' (like a Chinese Character) ; the housing is internally formed with a cavity; two sides of the bossing of the housing are respectively provided with a socket; the induction piece is provided with a fixing hole used for installation; the induction piece is fixedly connected with the socket of the housing by the fixing hole and a screw; the aperture of the fixing hole is larger that the aperture of the screw. The fixing hole takes on a waist-full form or other shapes. The cross section of the induction piece takes on a linear type. The cross section of the induction piece also can be L-shaped. The hem of the induction piece is formed with an induction surface which is a rectangle or a semicircle or other shapes, the optical shape is the semicircle. The ground water sensor has the beneficial effects that the ground water sensor has simple structure, can be directly arranged on corresponding devices needing to be monitored by the fixing hole, and has good popularity; the waist-full form fixing hole on the induction piece can regulate the relative length of the induction piece installation, works out the corresponding regulation according to different requirements, can meet different monitoring requirements, thus saving the space and reducing the cost.
Description
Technical field
The present invention relates generally to the accessory field of industry or civil equipment, mainly is a kind of ground water sensor.
Background technology
Ground water sensor commonly used at present, volume is relatively large, in the place of needs test, needs independent the installation, has taken certain space, is unfavorable for conserve space; For different equipment, according to no demand, need to be equipped with different transducers, be unfavorable for thin device, also increased the operating cost of equipment simultaneously, be unfavorable for saving cost.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, provides a kind of simple in structure, convenient water sensor efficiently.
The present invention solves the technical scheme that its technical problem adopts: this ground water sensor, mainly comprise shell and sensing chip, shell becomes several fonts, form cavity in the shell, the dual-side of shell bossing respectively is provided with a groove, sensing chip is provided with the fixing hole that usefulness is installed, and sensing chip is fixedly connected on groove on the shell by fixing hole, screw, and the fixing hole aperture is greater than the aperture of screw.
The shape of described fixing hole is waist type or other shapes.
Respectively be provided with an installing hole on the horizontal plane on described shell both sides.
The bossing of described shell and the contact position between the horizontal plane are provided with reinforcement.
The cross section of described sensing chip is type linearly, and the cross section of sensing chip also can be the L type, and the sensing chip flanging forms sensitive surface.
Described sensitive surface is rectangle or semicircle or other shapes, and optimum is semicircle.
Described shell is a plastic material, and described sensing chip is a stainless steel.
The effect that the present invention is useful is: the present invention is simple in structure, by installing hole, can be directly installed on the relevant device that needs monitoring, has good versatility; Waist type fixing hole on the sensing chip can be reconciled the relative length that sensing chip is installed, and according to different needs, makes corresponding adjusting, can satisfy different monitoring requirements.Both save the space, also reduced cost.

Embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in the figure, this ground water sensor, mainly comprise shell 1 and sensing chip 2, shell 1 is a plastic material, can generate by one-shot forming technique processing, processing technology is simple and convenient, cost is lower, sensing chip 2 is a stainless steel, good induction effect is arranged, very strong corrosion resistance is also arranged, the side of sensing chip 2 becomes the L type, sensing chip 2 flangings form sensitive surface, and the sensitive surface of sensing chip 2 is rectangle or semicircle, has increased the induction area of sensing chip 2, improved the sensitivity of transducer, 1 one-tenth a few font of shell, can finely must fit needs the instrument and equipment surface of monitoring, respectively is provided with an installing hole 7 on the horizontal plane on shell 1 both sides, be used to be installed in equipment, in the shell 1 is cavity 3, and the electronic chip of transducer and other parts are placed in the cavity 3, and the dual-side of shell 1 bossing respectively is provided with a groove 6, sensing chip 2 is fixed on groove 6 places, sensing chip 2 is provided with the fixing hole 5 that usefulness is installed, and is connected and fixed by screw 4 between sensing chip 2 and the shell 1, and fixing hole 5 is the waist type, fixing hole 5 apertures are greater than the aperture of screw 4, can regulate the installation length of sensing chip 2 according to different water surface monitoring requirements, to be suitable for and different occasions.The bossing and the contact position between the horizontal plane of shell 1 are provided with reinforcement 8, but have increased the bearing pressure of shell 1, have improved the intensity of self.
Whether the ground water sensor is mainly used in detection ground immersion, if immersion is arranged, the equipment that connects this transducer just can produce warning information, and the relevant responsible person of prompting plays supervisory function bit.But it has mainly utilized the electric conductivity of water, as two stainless steel sensor sheets 2 of ponding immersion sensor, or contacted on the sensitive surface of sensing chip 2, formed a conducting structure, transducer has made full use of this principle just Continuity signal has been passed to detector, finishes the detection of ground water alarm.
Whether the present invention can be contained in the ground of moving machine room, also can be contained in the beneath detection of air-conditioning and leak.
In addition to the implementation, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of requirement of the present invention.
