Abstract
An overload protection apparatus during raining for outdoor environment air monitoring instrument solves the problem that the outdoor environment air monitoring instrument will lead to the short circuit and damage of brushless motor, and then influence normal operation and generate economic loss in case of raining and snowing when the instrument works outdoor with people attention. It is characterized in that the utility model is composed of an outdoor environment air monitoring instrument (5), a power circuit (4) and a control circuit (3). An exserted cylindrical sensor (2) is arranged on the top of the outdoor environment air monitoring instrument. A heater (1) is arranged in the sensor (2), the output of the sensor (2) is connected with a controller (3) which is connected with the operating switch of the outdoor environment air monitoring instrument (5) through suction connection. The output of the heater (1) is also connected with the controller (3), and is also connected with the operating switch of the outdoor environment air monitoring instrument (5) through suction connection. The utility model is especially suitable for outdoor air sampling and monitoring.
Description
Technical field: the utility model is specifically related to a kind of outdoor environment air monitering instrument rainfall automatic overload protection device, belongs to electric mechanical instrument manufacturing technology field.
Technical background: at present; the environment that uses at outdoor environment air monitering instrument outdoor when doing the continuous sampling monitoring;, meet and snow, during unmanned owing to there is not protective device by outdoor environment air monitering instrument; will cause the brushless electric machine short circuit because of rainwater or snow-broth infiltrate outdoor environment air monitering instrument; damage motor, make outdoor environment air monitering instrument shut down or damage, can't normally monitor; influence work, cause economic loss.The purpose of this utility model is exactly for remedying above deficiency; what provide a kind ofly snows meeting to outdoor environment air plenum external environment air monitering instrument; during unmanned; can cut off the electricity supply automatically and quit work; can start work automatically again after it is fine; can do the continuous sampling monitoring, the outdoor environment air monitering instrument rainfall automatic overload protection device that also can not cause outdoor environment air monitering instrument to shut down or damage.
Technology contents: the utility model is to realize like this, outdoor environment air monitering instrument rainfall automatic overload protection device is made up of outdoor environment air monitering instrument (5), power circuit (4), control circuit (3), it is characterized in that going up end face at outdoor environment air monitering instrument (5) is provided with a cylinder shape sensor that exposes (2), in sensor (2), a well heater (1) is set; The output terminal that connects sensor (2) is provided with a controller (3) and is connected with the operating switch adhesive of outdoor environment air plenum external environment air monitering instrument (5); The output setting of well heater (1) also is connected in controller (3) and is connected with the operating switch adhesive of outdoor environment air monitering instrument (5).
Its principle of work of outdoor environment air monitering instrument rainfall automatic overload protection device is; meet and snow no outdoor environment air monitering instrument when outdoor people is worth machine; on sensor (2), ponding is arranged; sensor (2) will make relay (6) closure with referring to that signal is transferred on the controller (3); pulpit external environment air monitering instrument (5) is outage automatically; outdoor environment air monitering instrument quits work; after precipitation; controller (3) starts starts working the well heater (1) that is arranged in the sensor (2); ponding on the sensor (2) is dried; sensor (2) is started working; sensor (2) will will refer to that signal is transferred to controller (3) relay (6) is opened; pulpit external environment air monitering instrument (5) is energising automatically, and outdoor environment air monitering instrument works on.When a situation arises, continue to repeat above program.It is on duty that the advantage of employing outdoor environment air monitering instrument rainfall automatic overload protection device guarantees that exactly outdoor environment air monitering instrument need not personnel when working in the open air; avoid because of meet snow or outdoor environment air monitering instrument on have water to cause the brushless electric machine short circuit; damage motor; make outdoor environment air monitering instrument shut down or damage; can't normally monitor; influence work, cause the problem of economic loss.
Description of drawings:
Accompanying drawing is an outdoor environment air monitering instrument rainfall automatic overload protection apparatus structure schematic diagram
1. well heaters among the figure, 2. sensor, 3. controller, 4. power circuit, 5. outdoor environment air monitering instrument,
Specific embodiments: outdoor environment air monitering instrument rainfall automatic overload protection device is gone up end face at outdoor environment air monitering instrument (5) and is offered a circular osculum that is complementary with sensor (2) sectional area size as shown in drawings; sensor (2) mouthful is stretched out thus; expose a little higher than instrument plane; sensor (2) output terminal is provided with a controller (3) and is connected with outdoor environment air monitering instrument (5) starting switch adhesive; a well heater (1) is set in sensor (2); and the output terminal setting is connected in controller (3) and is connected with outdoor environment air monitering instrument (5) starting switch adhesive; air chamber external environment air monitering instrument rainfall automatic overload protection device of the present utility model is obtained obvious effects in the outdoor sampling experiment of Shanxi Province's Yangquan City Environmental Protection Agency, be adapted to the enterprise's production of medium and small dynamo-electric ability or the producer of outdoor environment air plenum external environment air monitering instrument production especially and form a complete production network.
