Abstract
The utility model discloses a detection and alarm device for stirring fan speed of an incubator, which comprises an incubator body and a motor, wherein the motor is mounted inside the incubator body, a spindle is mounted on the motor, a fan is mounted at the front end of the spindle, a sensor is mounted below the spindle and on the outer wall of the motor, a data line is arranged between the sensor and a computer arranged outside the incubator body, and the sensor is a Hall sensor. The detection and alarm device for stirring fan speed of the incubator is simple and reliable in circuit design, low in cost and failure rate, accurate in pulse counting of the sensor, rapid in response speed and good in practical application effect.
Description
Technical field:
The utility model relates to the hatch machine field, specifically is a kind of hatch machine agitation fan rotating speed detection alarm device.
Background technology:
Every hatch machine all has a cover big fan stirring system, to keep the uniformity of built-in temperature, always traditional hatch machine is to press the one stroke switch with spring under motor, detect the snap switch of having no progeny of belt, disconnecting the back reports to the police, this mechanical way fault rate height runs into the phase failure or the voltage slow-speed of revolution will detect to come out slowly.The utility model changes it into Hall element, not only solved above-mentioned problem effectively, and the sensor step-by-step counting is accurate, and response speed is by fast, and circuit is simple and reliable, and is with low cost, and practical application effect is good.
The utility model content:
The purpose of this utility model provides a kind of hatch machine agitation fan rotating speed detection alarm device, has solved the fault rate height of traditional mechanical type way effectively, and the phase failure or the voltage slow-speed of revolution detect a series of problem of not coming out slowly.
The technical solution of the utility model is as follows:
A kind of hatch machine agitation fan rotating speed detection alarm device, comprise hatch machine body, motor, in the described hatch machine body motor is installed, main shaft is installed on the motor, front-end of spindle is equipped with fan assembly, it is characterized in that: on described main shaft downside, the motor outer wall sensor is installed, is provided with data wire between the calculator in the described sensor and the hatch machine body outside.
Described hatch machine agitation fan rotating speed detection alarm device, it is characterized in that: described sensor is a Hall element.
The utility model has the advantages that:
The utility model circuit design is simple and reliable, and is with low cost, and fault rate is low, and the sensor step-by-step counting is accurate, and response speed is fast, and practical application effect is good.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
A kind of hatch machine agitation fan rotating speed detection alarm device, comprise hatch machine body 1, motor 2, motor 2 is installed in the hatch machine body 1, main shaft 3 is installed on the motor 2, main shaft 3 front ends are equipped with fan assembly 4, on main shaft 3 downsides, motor 2 outer walls sensor 5 is installed, is provided with data wire 7 between the calculator 6 in the sensor 5 and hatch machine body 1 outside; Sensor 5 is a Hall element.
It is 1400 rev/mins that the utility model detects rotation speed of the fan; in case after being lower than 1300 rev/mins; Hall element 5 will be transferred to detection signal and carry out software among the CPU of calculator 6 and handle by data wire 7; after analyzing relatively, send warning message; after rotating speed is lower than 1000 rev/mins; report to the police and the cut-out heating power supply,, play the effect of protection to prevent to burn egg.
