Also include two groups of sealed gland parts, the sealed gland part is nested with steel screw bushing, elasticity successively from outside to inside
Bushing and elastic caoutchouc set；Wherein, steel screw bushing outer wall is provided with tapered tread, and inside is smooth conical bore, and in screw-thread steel
The large end face of set is provided with two grooves, and described two grooves are located in same diametric(al)；The resilient bushing is one section of small end
Conical tube upward, elastic caoutchouc set inwall wrap up the mandrel or cable, outer wall and resilient bushing it is interior
Conical walls snug fit；
One group of larger sealed gland part is screwed into by its steel screw bushing in the conical bore on upper hemisphere and its elastic rubber
Gum cover is tightly enclosed on the mandrel；
Less one group of sealed gland part is screwed into by its steel screw bushing in the conical bore of the mandrel upper end and its elasticity
Rubber sleeve is tightly enclosed on the cable.
Further, one of breach is provided with the tube wall of the resilient bushing along its length.
Further, the width of the breach is more than resilient bushing outside diameter and the conical bore bottom hole where steel screw bushing
The difference of diameter.
The beneficial effects of the utility model：The utility model is taken the photograph using two groups of sealed gland parts to seal installation connection respectively
As the mandrel of head body and the cable of camera body, because seal cartridge assembly is formed using multilayer pipe fitting nesting, innermost layer
Elastic caoutchouc set closely tightly can be contacted with mandrel extruding, in the compression that steel screw bushing and resilient bushing circular conical surface coordinate
Under effect, elastic caoutchouc set closely can wrap its internal mandrel or cable, and realize sealing, meanwhile,
For different heavy water depths, elastic caoutchouc set can be held with a firm grip to realize by adjusting the amount of screwing of steel screw bushing, need
When increasing sealing intensity, continue to be threaded into steel bushing downwards, and two grooves be additionally provided with the end face of steel screw bushing,
Two grooves can be turned by a fork wrench with Π type structures etc, convenient regulation；In addition, steel screw bushing
Due to being connected using taper thread with mandrel or upper hemisphere, itself possess good hard sealing, screw thread can be achieved and connect
Directly sealed while connecing.

Fig. 2 is the structural representation of resilient bushing.
Fig. 3 is the top view of resilient bushing.
Fig. 4 is smaller one group of sealed gland part scheme of installation.
Embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the present utility model easily.
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Fig. 1-3, a kind of heavy water camera, including camera body 1, in addition to spheroid 2, the spheroid 2 it is upper
Half portion is divided into solid upper hemisphere 201, upper hemisphere 201 can be made of using rigid plastics, can also use stainless steel it
The steel of class are made, and the latter half of spheroid 2 is the cloche 202 of hollow ball shelly, i.e. the latter half is hollow-core construction, upper half
Spheroid 201 is connected as a single entity with cloche 202, non-dismountable connection.During fabrication, can be by the founding of cloche 202 in episphere
A complete spheroid is formed on body 201, itself and upper hemisphere 201 are used into epoxy resin after also cloche can be fabricated separately
AB glue, or other glue bondings for possessing more high bond strength are integrated.
The camera body 1 is fixed on connecting rod 3, and the connecting rod 3 is fixed on the lower end of mandrel 4 and camera body 1
Cable 5 passed upwards successively from connecting rod 3, mandrel 4, the lower end of the mandrel 4 is embedded in the upper hemisphere 201, to cause
The shooting end of the camera body 1 can be stretched into the cloche 202.
Also include two groups of sealed gland parts, the sealed gland part is nested with steel screw bushing 6, elasticity successively from outside to inside
Bushing 7 and elastic caoutchouc set 8；Wherein, the outer wall of steel screw bushing 6 is provided with tapered tread, and inside is smooth conical bore, and in screw thread
The large end face of steel bushing 6 is provided with two grooves 601, and described two grooves 601 are located in same diametric(al).The resilient bushing 7
For the conical tube of one section of small end upward, the elastic caoutchouc covers 8 inwalls and wraps up the mandrel 4 or cable 5, outer wall with
