Background technique
Assembling solar energy equipment (CSP) includes multiple paraboloidal mirrors (parabolic wire casing), and solar energy collecting is being set to
In the corresponding receiving tube flowed through for heat transfer fluid in the focus of the mirror.
Heat transfer fluid high temperature achieved allows to generate the oversaturated steaming across heat exchanger using the heat of accumulation
Vapour, for example, oversaturated steam can be such that turbine rotates and produce electricl energy.
In order to increase the efficiency of the device, mirror is configured to follow the apparent motion of the sun and rotate.Therefore, during daytime,
Receiving tube and paraboloidal mirror are integrally rotated and are connected with each other by means of fixed ground line.
Therefore, it is necessary to provide a kind of engaging portion of fluid-tight being arranged between rotation pipe and fixing pipe.For this mesh
, usually using the flexible pipe for the thermal expansion for also allowing receiving tube.
However, these pipes bear the antifatigue limit since they are subjected to reversed bending, twisting stress and high temperature.
The efficiency of CSP device is closely related with heat transfer fluid maximum temperature achieved.It therefore, can be steady at high temperature
The use of fixed substance is interesting.
It may not be able to be more than 400 DEG C of the upper limit that the use of conduction oil as heat transfer fluid, which is that operation temperature sets,.
Tested can be subjected to 600 DEG C operation temperature substance, the purpose is to the efficiency of aggrandizement apparatus.These objects
Some substances in matter --- mixture of such as fuse salt, such as NO3-N and NO2-N --- since its is nonflammable and
It does not pollute and also there is other advantage relative to conduction oil.
However, these substances when compared with conduction oil with relatively high setting temperature, value can be even up to
240℃.On the one hand, the use of these substances allows the energy efficiency of aggrandizement apparatus, but on the other hand, it can bring other
Technical requirements, for example need to prevent the solidification of heat transfer fluid, the solidification of heat transfer fluid in addition to formed in pipe content with
Outside, it is also possible to due to damaging pipe from the simultaneous volume increase of liquid phase is solid to during the melting step of solid residue
Structure.
For those reasons, pipe is by low-voltage and high peace times electric current (about 400A) is passed through to be kept by means of Joule effect
It can prevent the temperature of fluid sets.

It is connected to corresponding pipe 4,5 and is removably connected preferably by means of multiple bolts 20.
Similar with insulated combination portion 6 but conductive engaging portion 9 with conductive gasket includes the flange 25 for being fixed to the second pipe 7
With the flange 26 for being fixed to the second end pipe 8.Flange 25 includes radial conductive attachment 27, and the effect of attachment 27 will be said below
It is bright.Flange 25,26 is soldered to corresponding pipe 7,8 and preferably by means of multiple bolts 28 with removable side in which can be convenient
Formula connection.
Rotate engaging portion 11 (Fig. 2 and Fig. 3) includes sealing element 30 basically, and sealing element 30 is by a pair of opposite sealing ring
31, it 32 is formed, the pair of opposite sealing ring 31,32 has axially contact and by being placed in each sealing ring in the axial direction
31, the corresponding metal bellows 33,34 between 32 and corresponding intermediate tube 5,7 is urged into against each other.
Sealing element 30 is sealed by shell 35, and shell 35 includes the bell-shaped element being fixed on the flange 37 of the first intermediate tube 5
36 and the external barrel 38 of the second pipe 7 is extended axially to from bell-shaped element 36.
Shell 35 includes also solid in the opposite side relative to bell-shaped element 36 of sealing element 30 and in barrel 38
Determine to the flange 40 of the second pipe 7 and towards the wall of bell-shaped element 36 39.
Bearing 41 is provided between barrel 38 and wall 39 to allow the relative rotation of barrel 38 Yu wall 39.
Shell 35 also seals heating element 42 high-visible in figs. 3 and 4.

The heating element 42 that the electric current of the device passes through is flowed through to be heated by means of Joule effect, and to due to
It is bypassed and the rotation engaging portion 11 that will be " cold " originally and especially sealing element 30 and bellows by electric current as previously described
33,34 region is heated, therefore prevents the local solidification of heat transfer fluid.
Its advantage is clearly illustrated to the more careful close examination of unit 1 manufactured according to the present invention.
Connection unit 1 solves the above problem associated with the prior art.
It particularly, can be opposite in the case that unit 1 makes the electric current recycled in there are high temperature and pipe between pipe 2 and pipe 3
Rotation, and come heat sealed region domain using electric current.Therefore, on the one hand prevent heat transfer fluid solidifying in sealing area
Gu and on the other hand preventing and generating electric arc between the component in relative motion.The distortion of the mechanical organ of unit is tired
Labor stress can also be avoided by.
Unit 1 can be directly installed on CSP system in the case where not other attachment device or heat regulating device
On Trunk Line, therefore directly intercept the electric current flowed along device.
The unit is easy installation, does not need to safeguard and can be easy in the case of a fault to remove to replace component.
According to modification shown in Fig. 6, the second end pipe 8 forms the part of unit 1 and by similar with engaging portion 6
Insulated combination portion 54 is connected to the second pipe 7.In this case, the flange 26 of the flange 25 of the second pipe 7 and the second end pipe 8 every
From, and the attachment 27 for connection cables 50 extends from flange 26 rather than from flange 25.Even if This solution offers
Bypass sealing element 30 with the redundant electric being galvanically isolated.
Finally, it is evident that connection unit 1 can be made without departing from the modifications and changes of protection scope of the present invention.
Particularly, engaging portion 6,9 and 11 can be made in different ways.
If there is first end pipe 4 and the second end pipe 8, then first end pipe 4 and the second end pipe 8 can be by that will manage
2 and pipe 3 be fixed to engaging portion 6 and engaging portion 9 element any end member replace.
