Abstract
The utility model discloses a temperature-field measurement device for vacuum space, comprising a temperature detection disc. The temperature detection disc is connected with one end of a connection rod, and the other end of the connection rod is connected with an iron core. The an iron core is arranged inside a guide rod having one end enclosed, and a magnetic steel is arranged outside the guide rod corresponding to the iron core, the magnetic steel being slidable along the guide rod. According to the temperature-field measurement device for vacuum space provided by the utility model, no connection mechanism is required between the magnetic steel and the iron core, and the guide rod is mounted outside the vacuum chamber so as to form an enclosed environment with the vacuum chamber, thereby ensuring that the vacuum degree of the system are not influenced during the temperature-field measurement process.
Description
Technical field
The utility model relates to a kind of temperature field pick-up unit that provides, and particularly relates to temperature field pick-up unit in a kind of vacuum space.
Background technology
Vacuum system is used for the simulation space environment, and system vacuum degree and environment temperature are had higher requirements.The method that the detection space temperature field can be expected usually is that each point is arranged temperature detecting point in the space; Like thermopair etc.; This mode is owing to need the point of layout more right, and input cost is bigger, and when layout points is closeer; The temperature monitoring point can form obstacle when in this space, carrying out other work, and mini-system uses this type pick-up unit can reach request for utilization.Another kind of detection mode is the temperature detecting point that a face is set; The different temperatures face that records according to detection faces place diverse location makes up the temperature field; This mode need be positioned to detection faces the diverse location in space; When vacuum system is used this device, pass the vacuum tank wall between locating device and the temperature detection dish and be connected, will inevitably influence vacuum tightness.
So to above-mentioned prior art; The applicant thinks and is necessary to improve; The applicant has carried out number of patents document and non-patent literature retrieval for this reason; And do not see that referential teachings is arranged in the disclosed document, the technical scheme that will introduce below produces under this background.
Summary of the invention
The task of the utility model is the deficiency to prior art, and a kind of temperature field pick-up unit in the vacuum space that is used for is provided, and this device can not influence under the vacuum environment vacuum tightness situation, detects the temperature field of whole vacuum environment.
The task of the utility model is accomplished like this; Temperature field, vacuum space pick-up unit is characterized in that comprising the temperature detection dish, and said temperature detection dish links to each other with connecting rod one end; The connecting rod other end links to each other with iron core; Said iron core places in the guide pole of end sealing, and the outer and iron core correspondence position of guide pole is provided with magnet steel, and said magnet steel can slide along guide pole.
In a specific embodiment of the utility model, said magnet steel is a ndfeb magnet.
Beneficial effect: the technical scheme that the utility model provides, there is not bindiny mechanism between magnet steel and the iron core, guide pole is installed on that vacuum chamber is outer can to form a sealed environment with vacuum chamber, guarantees that in the testing process of temperature field vacuum tightness is unaffected in the system.
Description of drawings
Fig. 1 is the example structure synoptic diagram of the utility model.
Embodiment
Can be expressly understood the technical spirit and the beneficial effect of the utility model more for the auditor that the makes Patent Office especially public; The applicant general elaborates with the mode of embodiment below; But the description of embodiment all is not the restriction to the utility model scheme, any according to the utility model design done only for pro forma but not substantial equivalent transformation all should be regarded as the technical scheme category of the utility model.
Embodiment:
Ask for an interview accompanying drawing, guide pole 3 is a hollow tubular, and the one of which end is fixedly installed in outside the vacuum tank, and an other end seals.Be provided with iron core 4 in the guide pole 3, said iron core 4 is connected with an end of connecting rod 2, and the other end of connecting rod 2 is connected with temperature detection dish 1, is furnished with several thermopairs on the temperature detection dish 1, is used for the temperature of detected temperatures detection dish position.Said guide pole 3 outsides and iron core 4 correspondence positions are provided with magnet steel 5; Magnet steel 5 is a ndfeb magnet, and ndfeb magnet can endwisely slip along guide pole, through magneticaction; Drive iron core slip in the guide pole, and then make the temperature detection dish be positioned to the diverse location in the vacuum tank.Temperature according to diverse location temperature detection dish records can make up the temperature field in the whole vacuum tank.
Claims (2)
