Abstract
The utility model provides an intrinsic-safety-type water-existence sensor. The intrinsic-safety-type water-existence sensor comprises a body, two electrodes which are fixed on the body and contact with outside, and a cable which is fixed on the body, and is connected with the electrodes and is used for transferring electrical signals; the body is made from a corrosion-resistant material, and a sealing filler is filled inside the body; and the electrodes are made from a stainless steel material. Through adopting the corrosion-resistant material, the intrinsic-safety-type water-existence sensor of the utility model can ensure that water-existence signals can be outputted reliably in harsh conditions. According to the intrinsic-safety-type water-existence sensor which is of simplicity in overall whole structure, the sealing filler is filled inside the sensor, such that the sensor is not affected by the influence of the incline and swing of a ship in navigation, thereby enabling strong anti-interference ability.
Description
Technical field
The utility model relates to a kind of essential safe type the water signal transducer.
Background technology
When boats and ships navigated by water in water, inevitably there was the situation of ponding in the cabin bottom, more can occur the situation of damage and water inflow under accident or impact events, affected the security of boats and ships.In order to ensure the security of boats and ships, remind the crewman when cabin bilge ponding, carry out hydrophobic, when breakage is intake in a large number, take corresponding anti-heavy measure, boats and ships all should be installed bilge water alarm device for ships at the bilge.
Boats and ships bilge environmental abnormality is abominable, and there is a large amount of greasy dirts in the marine main engine cabin, and working temperature is up to 50 ℃; The boats and ships battery bay exists highly acid liquid and damp, and electrical equipment need to satisfy the requirement of ExibIICT1 explosive-proof grade; Boats and ships are being subjected to Lidar Equation can produce larger inclination, wave during navigation.The present water signal transducer that has can't guarantee so detecting safely, reliably flooded condition under the rugged environment, and of a great variety uneven.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of essential safe type that the water signal transducer is arranged, can be in rugged surroundings safe and reliable detection flooded condition.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: a kind of essential safe type has the water signal transducer, it is characterized in that: it comprises body, be fixed on the body with 2 electrodes of external world's contact and be fixed on the body and is connected the cable that is used for the transmission electric signal with electrode; Described body is resistant material, and is filled with airtight and watertight padding in the body; Described electrode is stainless steel material.
Press such scheme, described body is connected and composed by base and protective cover, and described electrode is fixed on the base, and described cable is drawn with signal receiving end from protective cover and is connected.
Press such scheme, described body is externally connected with installing card, and installing card is formed by two clamp connections.
The beneficial effects of the utility model are:
1, the utility model guarantees that by adopting resistant material reliably output has the water signal under abominable condition.
2, one-piece construction is simple, and inside is filled with airtight and watertight padding, and ship inclination when not navigated by water, the impact of waving have the strong characteristics of antijamming capability.
3, satisfy the requirement of ExibIICT1 explosive-proof grade.
4, each ingredient standardization, function modoularization are convenient to care and maintenance.
5, this device volume little, be convenient to install, with low cost.
Description of drawings
Fig. 1 is that figure is partly cutd open in the structural representation of the utility model one embodiment.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of base.
Among the figure: 1. body, 2. base, 3. protective cover, 4. electrode, 5. cable, 6. airtight and watertight padding, 7. installing card.
Embodiment
Fig. 1 is that figure is partly cutd open in the structural representation of the utility model one embodiment, Fig. 2 is the vertical view of Fig. 1, Fig. 3 is the structural representation of base, and this device comprises body 1, be fixed on the body 1 with 2 electrodes 4 of external world's contact and be fixed on the body 1 and is connected the cable 5 that is used for the transmission electric signal with electrode 4; Described body 1 is resistant material (selecting polytetrafluoroethylmaterial material in the present embodiment), and is filled with airtight and watertight padding 6 in the body 1; Described electrode 4 is stainless steel material.Body 1 is connected and composed by base 2 and protective cover 3, and electrode 4 screw threads are fixed on the base 2, and cable 5 is drawn with signal receiving end from protective cover 3 and is connected.Body 1 is externally connected with installing card 7, and installing card 7 is connected by screw by two clips and forms.
This device is assembled by following steps: 1) electrode 4 is threaded connection and is installed on the base 2; 2) cable 5 is connected with electrode 4; 3) protective cover 3 is threaded connection is fixedly mounted on the base 2; 4) adopting airtight and watertight padding 6 that base 2, protective cover 3 and cable 5 are watered envelope is integral; 5) clip was on protective cover 3 after installing card 7 was connected by screw.
When 2 electrodes contacted with water, water and electrode consisted of the loop by cable and signal receiving end, reached and judged the purpose that the water signal is arranged.
Described essential safe type is to adopt the explosion-proof principle that reduces ignition energy, what guarantee that circuit produces in the hazardous area opens short circuit cremate or thermal effect energy less than the minimum ignition energy of explosive mixture, can not light explosive mixture, guarantee to satisfy the requirement of ExibIICT1 explosive-proof grade.This sensor carries 5 meters JHRP85/SC, 2 * 1.0 type shipboard cable.The intrinsic safety performance parameter is as follows: maximum input voltage U
i=13V, maximum input current I
i=300mA, maximal input P
i=0.9W, maximum internal equivalent capacity C
i=0.00047 μ F, maximum internal equivalent inductance L
i=2.4 μ H.
