For making the utility model play better technique effect: further technical scheme is the graininess moisture absorption silica gel that above-mentioned moisture absorption silica gel is variable color.
Further technical scheme is that above-mentioned switching function post is to be installed on the base plate by the sealing function post.
Further technical scheme is that above-mentioned seal closure shell is the cylindrical of interior sky, and described base plate is circular, and the seal closure shell is connected to connect by thread seal with base plate.
Further technical scheme is that above-mentioned checkout equipment probe is sensing coil and capacitor board.
A kind of method that improves power-frequency electric field strength checkout equipment accuracy, its method is as follows:
Select plastic production seal closure shell and base plate;
Mounting base and switching function post form bottom deck assembly on base plate;
Pedestal by passing base plate and the feeler lever of checkout equipment be fixed whole bottom deck assembly;
With being arranged on the pedestal of checkout equipment probe;
Moisture absorption silica gel is put into the seal closure shell, and seal closure shell and base plate are tightly connected.
Further method is to install before the switching function post on the above-mentioned base plate, and a sealing function post is installed first.
Further method is that above-mentioned being tightly connected is threaded for dismountable.
The beneficial effect that adopts technique scheme to produce is: the utility model is a kind of to improve the device of power-frequency electric field strength checkout equipment accuracy owing to be that the checkout equipment probe is arranged in seal closure shell and the formed annular seal space of base plate, so the relative humidity of extraneous air can not impact the detection accuracy of checkout equipment probe; In annular seal space, fill in addition moisture absorption silica gel, both can keep the air aridity in the annular seal space, can prevent to a certain extent that again the loosening rear steam of seal closure shell and base plate sealing from entering the interior impact of annular seal space and detecting, thereby improved the accuracy of checkout equipment.
Description of drawings
Fig. 1 is a kind of structural representation that improves an embodiment of device of power-frequency electric field strength checkout equipment accuracy of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1 shows, an a kind of embodiment who improves the device of power-frequency electric field strength checkout equipment accuracy of the utility model: a kind of device that improves power-frequency electric field strength checkout equipment accuracy, comprise the seal closure shell 1 and the base plate 2 that mutually are tightly connected, described base plate 2 be provided with can installation and measuring equipment probe pedestal 3 and can control the switching function post 4 of checkout equipment probe, described pedestal 3 passes base plate 2 and is connected with the feeler lever of checkout equipment, and described switching function post 4 passes base plate 2 and extends to base plate 2 outsides; Described seal closure shell 1 and base plate 2 are tightly connected and are provided with moisture absorption silica gel in the annular seal space 5 of rear formation.
According to a kind of another embodiment that improves the device of power-frequency electric field strength checkout equipment accuracy of the utility model, moisture absorption silica gel is the graininess moisture absorption silica gel of variable color.Employing can variable color moisture absorption silica gel, descend to a certain degree rear water-intake capacity because it has suction, color can change, such as becoming redness, the staff just can change moisture absorption silica gel timely, has preferably water-intake capacity to keep in the annular seal space 5 moisture absorption silica gel always.
According to a kind of another embodiment that improves the device of power-frequency electric field strength checkout equipment accuracy of the utility model; because switching function post 4 needs often movable; must there be the gap between the perforate on itself and the base plate 2; so switching function post 4 is installed on the base plate 2 by sealing function post 6, like this can maintained switch functional column 4 and base plate 2 between the gap can not cause flowing between annular seal space 5 and the extraneous air.
According to a kind of another embodiment that improves the device of power-frequency electric field strength checkout equipment accuracy of the utility model, seal closure shell 1 is the cylindrical of interior sky, described base plate 2 is circular, it is to connect by thread seal that seal closure shell 1 is connected with base plate, it is simple that such structure not only manufactures technique, cost of manufacture is low, and also very easy in installation and removal, is conducive to the moisture absorption silica gel of later stage replacing annular seal space 5 inside.
