Description
Technical field
The present invention relates to the underwater robot technology, specifically a kind of underwater control cabin capable of detecting seal condition.
Background technology
Along with the increase of operating water depth, underwater robot has obtained using widely in various prospectings under water and Underwater Engineering at present.Underwater robot includes cable underwater robot, no cable underwater robot and seabed reptiles underwater robot.Every motion and the operation function under water control system that all be controlled by underwater robot of underwater robot in water.Control cabinet is a underwater robot vitals of control system under water, and according to the needs of control system, computing machine, power supply, fibre multiplexer, communication and data converting circuit plate etc. under water can be equipped with in control cabinet inside.All power and control line are by underwater electrical connector and underwater connection box on the connector end cap in the control cabinet, and external units such as hydrostatic control clack box link to each other.
Wherein: control cabinet is generally a dry type (not oil-filled, inner normal pressure) cylindrical pressure-resistant seal cabin body, is made up of the cylindrical cabin body of centre and the capping at two ends, O type rubber seal is housed to guarantee the requirement of control cabinet watertight between cabin body and capping.Cabin body and capping wall thickness are determined by the underwater robot operating depth.In the prior art, the cabin body adopts bolt to be connected with capping, and this can cause control cabinet physical dimension to increase.Under water when robot debugging and on-site maintenance, often open control cabinet, electronic devices and components in debugging and the detection cabin in addition.Behind the batten down, can't use the sealing condition of instrument detecting control cabinet O type rubber seal again, can only be with batten down person's experience batten down, just in case there is leakage will cause very big loss.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of this invention is to provide the control cabinet under water that a kind of size is little, can detect sealing condition.
To achieve these goals, technical scheme of the present invention: the cabin body of end cap and connector end cap is installed, establishes twice O type rubber seal between end cap and connector end cap and the cabin body; It is characterized in that: on described end cap and connector end cap and outer rim that the cabin body is connected, establish a boss, also establish the boss of a structural symmetry on cabin body and end cap and the outer rim that the connector end cap is connected, be integral with clamping steel band installation end cap and connector end cap and cabin body, on connector end cap, end cap, establish a vacuum detecting hole respectively, between the twice O type rubber seal, the joint of end cap and connector end cap and cabin body;
Described two boss be combined as rectangle or V-structure, described clamping steel band adopts corresponding structure after the combination with two boss.
The present invention has following advantage:
1. because the present invention is provided with vacuum detecting hole on end cap, the sealing condition of the control cabinet under water that adopts the present invention can utilize vacuum plant to detect to use on the various underwater robots.
2. because connector end cap of the present invention by the aluminium alloy making, and utilizes V-type to clamp steel band locking cabin body and end cap, avoid using a plurality of bolt connecting modes, weight is lighter, and size is less; In addition, seawater corrosion resistance of the present invention, safe and reliable, can on various underwater robots, use.
Description of drawings

Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
Embodiment 1
As shown in Figure 1, 2, the present invention's control cabinet under water comprises the cabin body 4 that end cap 7 and connector end cap 1 are installed, and establishes twice O type rubber seal 2 between end cap 7 and connector end cap 1 and the cabin body 4; It is characterized in that: on described end cap 7 and connector end cap 1 and outer rim that cabin body 4 is connected, establish a boss, also establish the boss of a structural symmetry on cabin body 4 and end cap 7 and the outer rim that connector end cap 1 is connected, steel band 5 is installed end cap 7 by the locking on it with screw bolt and nut and connector end cap 1 is integral with cabin body 4 with clamping, on connector end cap 1, end cap 7, establish a vacuum detecting hole 6 respectively, between the twice O type rubber seal 2, the joint of end cap 7 and connector end cap 1 and cabin body 4.Described two boss of present embodiment be combined as V-structure, described clamping steel band 5 adopts V-structures.
The course of work of the present invention and principle are as follows:
Be weight reduction, connector end cap 1, cabin body 4, end cap 7 is made by aluminium alloy.The quantity of connector connecting hole and size are decided by actual demand on the connector end cap 1, be processed with twice O type circle annular groove at connector end cap 1 with cabin body 4 contact positions, having a vacuum detecting hole 6 that extends between the twice O type circle annular groove at the end face of connector end cap 1.End cap 7 is disc, is being processed with twice O type circle annular groove with cabin body 4 contact positions, is having a vacuum detecting hole 6 that extends between the twice O type circle annular groove on the end face of its end cap 7, is used to detect the sealing condition of twice O type circle.Equipment in the control cabinet is put into taking-up, and Installation and Debugging are all undertaken by opening end cap 7.Clamp steel band 5 and made by stainless steel, its xsect is V-shaped, and the locking screw bolt and nut is installed at the two ends that clamp steel band 5.Cabin body 4 is a cylindrical drum, and two ends link to each other with end cap 7 with the connector end cap 1 that O-ring seal is housed respectively by clamping steel band 5, screw the locking screw screw bolt and nut on the V-type steel band after, the three can fuse.Along with the increase of the depth of water, cabin body 4 can be pressed tight more with the connector end cap 1 on the left side and the end cap 7 on the right more.
The principle of utilizing vacuum detecting seal of vessel situation is the container for a good seal, with vacuum pump with its extracting vacuum after, its vacuum tightness can remain unchanged; Reduction just shows that sealing is bad as vacuum tightness, and leakage is arranged.
Vacuum plant comprises vacuum pump, pressure vacuum gauge, stop valve, vacuum test joint etc.The testing procedure of vacuum plant detection control cabinet O type circle sealing condition is as follows:
1) behind the control cabinet batten down, the vacuum test joint is installed at O type circle vacuum detecting hole 6 places.
2) vacuum pump starts vacuum pump with after test splice is connected, and the control cabinet internal pressure is evacuated to 7000Pa-9000Pa, closes stop valve.
3) keep-uped pressure 3 minutes.Do not reduce (variation) as vacuum tightness, can assert O type circle good seal less than 1%.As vacuum tightness reduction is arranged, show that O type circle sealing is bad, batten down detection again after the problem is found out in control cabinet inspections of need opening the cabin.
4) after detection finishes, vacuum test joint on the two end cap is dismantled.Before the following water shutoff of vacuum test hole to be installed, prevent that seawater from entering.
Difference from Example 1 is: structure can be rectangle after the combination of two boss of the present invention.
The aseptic technic that the present invention can utilize vacuum plant to detect the vacuum detecting Sealing Technology that control cabinet adopted, its manufactured materials and the material of sealing condition under water is practicable through evidence.This control cabinet under water is in light weight, simple in structure, safe and reliable, seawater corrosion resistance, and applied range is convenient to install on underwater vehicle.
