The invention relates to a mine-used intrinsically safe electrode type coal level sensor, which comprises a sensor shell (1), and is characterized in that a label bonding plane (2) is arranged on an upper part of the sensor shell (1); a rubber sealing gasket (3) is arranged between the sensor shell (1) and the label bonding plane (2); a conical sensor shell (6) is connected to a lower part of the sensor shell (1); an electric adapter (7) is arranged on a right side of the conical sensor shell (6); a pothook (4) capable of swinging in dual directions is arranged on the conical sensor shell (6); a control circuit board (5) is arranged in the conical sensor shell (6); an upper contact guide rod (10) is connected to a bottom part of the conical sensor shell (6); and a lower contact guide rod (12) is arranged in the upper contact guide rod (10). The mine-used intrinsically safe electrode type coal level sensor has the advantages of low price, compact structure, small volume, convenience in transportation, installation and debugging, and the like.
Description
Technical field
The present invention relates to a kind of coal site sensor, specifically a kind of mining intrinsic safety electro utmost point formula coal site sensor can be widely used in the industries such as colliery, building materials, coal preparation plant, electric power, harbour, is used for detecting the material level protection of coal solids balk cargo.
Background technology
China is producing coal, use coal big country, the coal tonnage detection device that uses under the colliery safe can under coal mine gas be arranged, the environmental work of coal dust explosion hazard.Use non-contact measurements (such as ultrasound wave) under the ore deposit at present, this type of measuring instrument is expensive, is not fine to the unfixed dump effect of shape more.
Summary of the invention
[0004] the present invention seeks in order to overcome defects, provide a kind of cheap, compact conformation, volume little, transport, install, debug easily mining intrinsic safety electro utmost point formula coal site sensor.
Technical scheme of the present invention is:
A kind of mining intrinsic safety electro utmost point formula coal site sensor, comprise sensor outer housing, described sensor outer housing top is the label bonding plane, be provided with rubber gasket between sensor outer housing and the label bonding plane, the sensor outer housing bottom connects the cone-shaped sensor shell, cone-shaped sensor shell right side is provided with electrical connector, but the cone-shaped sensor shell is provided with the double-swing hook, be provided with control circuit board in the cone-shaped sensor shell, the cone-shaped sensor outer casing bottom connects upper contact guide rod, is provided with lower contact guide rod in the upper contact guide rod.
Be provided with check washer between described upper contact guide rod and the cone-shaped sensor shell.
Be provided with the O RunddichtringO between described check washer and the cone-shaped sensor shell.
Described upper contact guide rod with under contact and be provided with insulating ferrule between the guide rod.
The invention has the beneficial effects as follows:
Mining intrinsic safety electro utmost point formula coal site sensor of the present invention, be mining intrinsic safety electro gas equipment, be applicable to have under the coal mine environment of gas, coal dust explosion hazard, also be applicable to the rugged surroundings such as metallurgy, building materials, mine and coal preparation plant, steel plant, cogeneration plant, harbour.The height material level that can be used for all kinds of dumps is reported to the police, and each one tunnel output of the passive contact of normally-open normally-close is arranged, and can shut down and locking equipment (such as motor), guarantees the safety of the person and equipment, can also control external unit etc.
Mining intrinsic safety electro utmost point formula coal site sensor of the present invention can be widely used in having in the environment of damp (methane) and coal dust, and it is simple to operate, and is easy to use.Just can play the controlling alarm effect as long as be installed in the suitable position of coal charge heap.
That mining intrinsic safety electro utmost point formula coal site sensor of the present invention has is cheap, compact conformation, volume are little, transportation, install, the advantage such as debugging is convenient.
Mining intrinsic safety electro utmost point formula coal site sensor of the present invention also has anti-coal ash, non-maintaining, highly sensitive advantage.
