The cleannes video check of flow distribution plate upper surface and the first support plate lower surface.Due to the limitation in space, complete probe is led
It can not be directly entered evaporator room to device, therefore, during the inspection process, the guider length used is set detection zone
The half of length of field is checked from evaporator both sides respectively, and needs repeatedly to shift equipment, along with evaporator is another
Side checks that locational space is excessively narrow, operates relative difficulty, in this way, not only increasing labor intensity, but also reduces inspection efficiency；
It being influenced by evaporator internal structure, probe needs to enter the region for needing to check by certain angle by guider,
In view of the resistance of probe disengaging elbow, angle of bend should not be too large, therefore, at region between entering pipe, not due to angle
It is suitable, often there is being unable to judge accurately position between pipe, causes probe to advance between pipe difficult；Checking the first support plate lower surface
When region, between probe need to travel upwardly about 40 pipes, due to the characteristic of itself of popping one's head in, that pops one's head in after traveling a distance is strong
Degree is not enough to that it is supported to continue up traveling, so that it is unable to reach Checking on effect, all big discounting of the quality and completeness to video
Button.

Specific implementation mode
The explanation of following embodiment is refer to the attached drawing, can be to the particular implementation implemented to example the utility model
Example.
The utility model provides a kind of video inspection device, and for checking nuclear power plant equipment inside, construction is such as
Shown in Fig. 1, including：
Segmented guiding mechanism 1, adjustable elbow 2, probe fixed plate 3 and the spy being arranged inside probe fixed plate 3
First 4.
Wherein, as shown in Fig. 2, segmented guiding mechanism 1 is including 5, growth feeler levers 6 of a guide pipe and by butterfly
The locking member that shape nut 7 and bolt 8 form.Bolt 8 is welded on the outer surface of guide pipe 5, and wing nut 7 can be on bolt 8 certainly
By rotating and not having the risk fallen, the wing nut 7 in detection process is avoided to fall to inside steam generator.Pass through butterfly
The fastening of shape nut 7 can by guide pipe 5 with increase together with 6 interlocking of feeler lever, it is complete for covering to increase the distance of detection
Portion's detection range.Under the release conditions of wing nut 7, can guide pipe 5 and growth feeler lever 6 be freely separating and be convenient for carrying.Butterfly
The rotation of shape nut 7 can be completed by human hand, need not be by other utensils so that splicing and mask work are easier.
As an example, guide pipe 5 and growth feeler lever 6 select rectangular stainless steel tube to be made in the present embodiment, in other embodiments, lead
To pipe 5 and increase the tubing that feeler lever 6 can be other shapes.
Adjustable elbow 2 is connected to one end of guide pipe 5, as shown in figure 3, its structure includes：90 ° of stainless steel bend 9,
Thin slice nut 10, adjusting bolt 11 and adjustment sheet 12.One end of 90 ° of stainless steel bend 9 connects guide pipe 5, and the other end is
Probe outlet, thin slice nut 10 are welded on the outer surface of probe outlet, are opened in the elbow of the silk aperture position of thin slice nut 9
One through-hole so that adjusting bolt 11 can be penetrated into the inside of stainless steel bend 9, withstand and push 12 run-off the straight of adjustment sheet.It adjusts
Nodal plate 12 is made of nonmetallic materials, has certain flexibility, one end is fixed on the inner surface of stainless steel bend 8.
Probe 4 needs guiding through the outlet for the inside arrival stainless steel bend 9 for increasing feeler lever 6, guide pipe 5 and stainless steel bend 8
End.In order to enable probe 4 that there is enough intensity to reach specified inspection area, two pieces of probes are added outside probe and are fixed
Plate 3, probe fixed plate 3, which is selected, PE plates that are certain flexible and having the intensity needed for checking, and onboard opens one and half
The straight slot of circular cross-section, 3 width of fixed plate of popping one's head in as an example, in the present embodiment select 10mm, and the depth for opening slot is radius
The semi arch of 2mm can be made accordingly in other embodiments according to the size and probe size dimension of different elbow bores
Change.
Before probe 4 advances to stainless steel bend 9, adjusting bolt 11 is in original state, does not withstand adjustment sheet 12, that is, adjusts
Nodal plate 12 is tightly attached to the inner surface of stainless steel bend 9, to make the probe 4 for being enclosed with fixed plate 3 smoothly stretch out stainless steel bend 9
Outlet end, when pop one's head in 4 stretch out the outlet end certain distance of stainless steel bends 9 after, can be according to the angle demand of inspection, by twisting
The tight adjusting bolt 11 that adjusts pushes adjustment sheet 12 that corresponding angle is presented, so that probe can check corresponding position.It is whole
A adjustment process, which needs to adjust before checking that work starts, to be finished, and the effect of inspection can also be improved by neither influencing operating process in this way
Rate.
In an alternate embodiment of the invention, the video inspection device of the utility model can be used for steam generator flow distribution plate or first
The video check of support plate.
By above description it is found that the advantageous effect of the utility model embodiment is：
The video inspection device is simple in structure, easy to operate when in use, and performance is stablized.It is shunted when for steam generator
When plate or the video check of the first support plate, due to the limitation of evaporator room space, the device of the utility model is original
Device basic on sectional design has been carried out to guider, disposable covering all inspections are reached by the combination of two feeler levers
The purpose for looking into region, avoids the being dismounted for multiple times of equipment, and the accessibility of device after connection is in turn ensured while being convenient for carrying,
It greatly reduced labor intensity；It is influenced by evaporator internal structure, angle regulator is added in original elbow, visited
Head exit angle after elbow can be adjusted as needed, and not only ensure that the original traveling of probe is unobstructed in this way, but also
It reduces probe and enters the difficulty for specifying region, be greatly improved on observation visual angle and video quality；In order to improve
The problem of probe can not reach specified inspection area because of intensity deficiency is additionally arranged two PE plates on the basis of probe does not become itself
Probe is reinforced and is guided, using the characteristic of PE plate materials, the while of popping one's head in is being protected greatly to increase its intensity again,
And have good flexibility, it is unobstructed not only to have met probe traveling process, but also its examination scope is made to be expanded.
Above disclosures are merely preferred embodiments of the utility model, with this utility model cannot be limited certainly
Interest field, therefore equivalent variations made according to the claim of the utility model still fall within the scope of the utility model.
