Description
Technical field
The utility model relates to sensor, is specifically related to a kind of down-hole with the protection box of sensor and terminal box.
Background technology
Because subsurface environment is complicated and changeable, in order to guarantee safety in production, people need to obtain the situations such as the temperature, humidity, oxygen concentration, gas concentration lwevel of down-hole at any time, must be by means of sensor.Sensor is exactly a kind of pick-up unit, can experience measured information, and the information that detection can be experienced, be for conversion into according to certain rules the information output of electric signal or other desired forms, with the requirements such as transmission, processing, storage, demonstration, record and control of satisfying information, it is the primary link of realizing automatically detection and automatic control.
But because subsurface environment high humidity, harmful etchant gas are many, dust is large in recovery process, and these factors all will affect the detection degree of accuracy of sensor, and be unfavorable for the serviceable life of sensor.So use the outside of the sensor that uses such as the down-hole all to be provided with protective device at special occasions.At present main protective device has: a class is fabric protective sleeve, namely puts a cloth cover outside sensor; Another is aluminum alloy protective cover, adds the protection box of an aluminium alloy outside sensor.These two kinds of protective devices have shortcoming as follows:
1, its dust-proof effect of cloth shell type protective device is not obvious, and coal dust puts the same cleaning that is difficult at cloth, and in moist tunnel, coal dust is gathered into piece especially, needs often to change the cloth cover; The cloth cover can not play the effect of protection against the tide, shatter-resistant in addition.
2, cloth shell type and boxlike protective device, its inner sensor easily makes moist, and in moist tunnel or the large tunnel of trickle, can not well protect sensor, so that sensor makes moist, intakes, affects normal operation of sensor, easily produces false alarm.
3, to the aviation plug of sensor without any protection, the easy rust in aviation plug place extremely causes sensor to damage.
4, the terminal box that is connected with the sensor aviation plug can not play a protective role, and leads in underworkings, can not play protection against the tide, shatter-resistant effect by the butted line box.Easily cause the connection short circuit, open circuit and cause the sensor cisco unity malfunction, impact is produced.
5, the sensor body itself is blocked, be not easy to daily observation and maintenance.
The utility model content
The utility model will solve above-mentioned deficiency exactly, and a kind of have sensor and terminal box protection box dustproof, moistureproof, shatter-resistant are provided.
In order to reach above-mentioned effect, the utility model provides the protection box of a kind of down-hole with sensor and terminal box, comprises at the bottom of the box and lid, passes through the chain connection of an end at the bottom of described lid and the box; Described lid is provided with vocal hole, described vocal hole peripheral hardware protective cover; Be provided with that wrapping post, left side are provided with hook, the right side is provided with draw-in groove in the middle of at the bottom of the described box; The bottom of described protection box is provided with the line hole.
Better for the sealing effectiveness that makes this protection box, prevent that seepage from affecting equipment to the box body lane, the opening and closing place at the bottom of described lid and the box is stepped, respectively is provided with button and knob down at the offside of hinge, upper button and knob down have been to be easy to open or to close lid.
Top at the bottom of the described box is provided with the fixedly ear hanging pieces of usefulness, and protection can be suspended on needs the sensor surveyed area, and conveniently moving is quick.
All be to be made by organic glass at the bottom of described lid and the box, sensor without any blocking, is convenient to observe and maintenance repair, dust is easily cleared up.
Described line hole is terminal box line hole and pickup wire hole.
Box of the present utility model bottom minute can be divided into four, and the left terminal box fixed area that is communicated with for circuit is positioned over terminal box on the hook, and its connecting line passes in and out in the terminal box hole of bottom at the bottom of the box; The butted line box plays protection against the tide, shatter-resistant, dustproof effect; Middle top at the bottom of the box is that circuit twines the district, makes unnecessary circuit more attractive in appearance in box body, and overhauls after reserving unnecessary circuit and being convenient to; Drying agent so that the board plate is more beautiful and clean, is put into so that box body avoids other reasons to make moist for patrolling and examining board plate and drying agent rest area simultaneously in middle below; The right side is the sensor put area, sensor is fixed in the draw-in groove bottom connecting line hole turnover of the connecting line of its sensor at the bottom of the box.
The utility model all is located at sensor, terminal box and unnecessary connecting line thereof in the protection box, each equipment is played the effects such as dustproof, waterproof, has protected the normal operation of each equipment, reduces its damage.
The position that lid of the present utility model is positioned at the sensor hummer is provided with a plurality of vocal holes, adds a protective cover outside vocal hole again, and lower side space reserves, and under the prerequisite that ensures the hummer sounding effect, can play better protection against the tide, waterproof action again like this.
Protection box good sealing effect of the present utility model, there is corresponding airtight measure at each position, can better play the effect of dustproof, moistureproof, waterproof, shatter-resistant, and the harm that may be subject to sensor and circuit thereof has reliable protection.Guarantee the normal operation of sensor and circuit, reduce the damage of equipment, and then when saving cost, guarantee the safety in production of mine.Should protect simultaneously basin attractive in appearance, generous, practical.
