Summary of the invention
The objective of the invention is to overcome existing civilian and industrial liquid level detector and can't directly use the deficiency in the level detection of deep-sea, a kind of electric pole type liquid-level probe that can be used for deep-marine-environment is provided.This liquid-level probe can be used for the level detection under the complicated rugged surroundings such as deep-sea high pressure, deep-etching.
For realizing above purpose, the technical scheme below the present invention has taked: a kind of electric pole type liquid-level probe that can be used for deep-marine-environment includes and is wholely set and bolt block and bolt that the titanium alloy of internal run-through is processed into; Installing plate; Two probes by titanium alloy is processed are perfused with extraordinary encapsulant vulcanizate in bolt block and bolt, also be provided with cable in the bolt block; Two probes are imbedded in the bolt block, and probe end also is connected with cable; Be provided with screw thread at said bolt outside surface, and the nut that matches mutually with bolt; On a side, have groove, in said groove, be placed with O-ring seal on the bolt block, near bolt block.
Also include installing plate, installing plate passes bolt and is located at the bolt block surface, and said cable is drawn two branch roads, branch road ground connection wherein, and another branch road is connected with resistance in series respectively, and draws lead and detect control chip and be connected at the voltage detecting end.
The technical solution adopted for the present invention to solve the technical problems is: utilize titanium alloy material to be processed into screw bolt and nut; With the boring of bolt middle part; Imbed two titanium alloy pins, spacing 5～8mm, wherein an end exposes 2～3mm; Other end end is with wire bonds and draw, and these two titanium alloy pins are as two electrodes of level detection.In bolt hole, injecting extraordinary encapsulant vulcanizes.Lean on screw thread one side to drive a circular trough at bolt, in groove, place circle, be used for carrying out when mounted the seawater sealing.
The present invention compared with prior art; Has following advantage: overcome existing civilian and industrial liquid level detector and can't directly use the deficiency in the level detection of deep-sea; A kind of electric pole type liquid-level probe that can be used for deep-marine-environment is provided; This liquid-level probe can be used for the level detection under the complicated rugged surroundings such as deep-sea high pressure, deep-etching, and is easy to use.

Embodiment
Below in conjunction with accompanying drawing and embodiment content of the present invention is explained further details.
Embodiment:
See also shown in Figure 1; A kind of electric pole type liquid-level probe that can be used for deep-marine-environment includes and is wholely set the also bolt block 2 and 20, two probes 1 of bolt of internal run-through; In bolt block 2 and bolt 20, be perfused with encapsulant vulcanizate 6; Also be provided with 7, two probes 1 of cable in the bolt block 2 and imbed in the bolt block 2, probe 1 is terminal and be connected with cable 7; Be provided with screw thread 5 at bolt 20 outside surfaces, and also comprise the nut 8 that matches mutually with bolt 20; On a side, have groove 3, in groove 3, be placed with O-ring seal 4 on the bolt block 2, near bolt block 2.In the present embodiment, groove 3 is an O type groove, and O-ring seal 4 is the O type rubber seal of matching with O type groove.
See also Fig. 2 and shown in Figure 3, also include installing plate 9, installing plate 9 passes bolt 20 and is located at bolt block 2 surfaces; The nut 8 of firmly screwing; O type rubber seal 4 pressurizeds and installing plate 9 driving fits, cable 7 is drawn two branch roads, wherein a branch road ground connection; Another branch road is connected with resistance in series 10 respectively, and draws lead and detect control chip and be connected at voltage detecting end 11.
Bolt block 2, bolt 20, probe 1 are processed by titanium alloy respectively.
This deep-sea liquid-level probe is put into seawater to be tested; Its resistance is in 50～100K Ω, for Transistor-Transistor Logic level standard commonly used, when control chip input voltage Vcc is 5V; High-level input voltage Vih＞=the 2V of its requirement, low-level input voltage Vil＜=0.8V.At this, suppose that the seawater conducting resistance is 100K Ω, requiring the low level of input sign seawater conducting this moment is 0.8V, establishing the resistance of connecting with seawater is R, then has: the V/R of 0.8V/100K Ω=(5-0.8).
