Abstract
The invention relates to an anti-fog protection device of a borehole television probe, and belongs to the field of manufacturing of engineering detection equipment. The anti-fog protection device of the borehole television probe consists of an outer tube connector, a seal ring, a transparent isolating layer, a light transparent cover, an outer tube tail seat and a dehumidification layer, wherein the transparent isolating layer is pressed in the upper end of the light transparent cover; the lower end of the light transparent cover is provided with the dehumidification layer; an independent closed space is formed between the light transparent cover and the outer tube tail seat of the anti-fog protection device, so that fog is prevented from being formed in the light transparent cover, and fog can also be prevented from being produced by temperature difference above and below ground; meanwhile, moisture in the closed space can be removed to the greatest extent by the dehumidification layer which is arranged on the outer tube tail seat, and further, the occurrence of the fog is reduced to the greatest extent. The anti-fog protection device has the advantages of rational design, simple structure and convenience in mounting and use; meanwhile, clear photographing of the borehole television probe during work can also be guaranteed, the construction time is effectively saved, and the construction risk is reduced.
Description
Technical field
The present invention relates to a kind of antifog protective device of borehole television probe, belong to the engineering detecting manufacturing field of equipment.
Background technology
Borehole television is used by a large amount of in the engineering exploration field; The borehole television probe places in the seal protecting device usually; In the actual use of borehole television system, because existence underground and the ground temperature difference, and borehole television is popped one's head in the course of the work, and partial circuit generates heat; The inner and outer wall of borehole television protective device diffuser is hazed, and that takes in directly causing constructing is not fogging clear.Solution commonly used is; The mist of outer wall perhaps waits with the rag wiped clean and gets into fog Lock-out under water, but then can't directly handle for the fog of glass tube inwall, in the time of can only treating that the temperature difference reaches unanimity; Let its Lock-out, so direct site operation progress that influences.
Summary of the invention
To the problem of above-mentioned existence, the object of the present invention is to provide a kind of borehole television probe protective device that can prevent down effectively in working order and handle the phenomenon that hazes automatically, to achieve these goals, its technical solution is:
The antifog protective device of borehole television probe is made up of outer tube connector, sealing ring, lamina septum pellucidum, diffuser, outer tube tailstock and dehumidifying layer, and described diffuser upper end is provided with lamina septum pellucidum, and lamina septum pellucidum is the dome shape; Have annular groove on the outside wall surface of lamina septum pellucidum; Be provided with sealing ring in the groove, lamina septum pellucidum is fitted in the diffuser, is provided with the dehumidifying layer in the diffuser lower end; The dehumidifying layer is positioned at outer tube tailstock top; Described dehumidifying layer is made up of loam cake, lower cover and desiccant, and desiccant is contained between loam cake and the lower cover, on cover and have equally distributed aperture.
Owing to adopted above technical scheme, the antifog protective device of the present invention is provided with lamina septum pellucidum in the diffuser upper end; Make to form an independently enclosure space between separation layer, diffuser and the outer tube tailstock, the working space of this enclosure space and probe separates, and has avoided probe to get in the diffuser because of heating causes the phenomenon that hazes at work; Also can avoid on the ground with the underground temperature difference and hazing of causing, the desiccant that is placed on the outer tube tailstock simultaneously can be removed the aqueous vapor in the enclosure space to greatest extent, and then reduces the generation of fog to greatest extent; Antifog protective device of the present invention is reasonable in design; Simple in structure, easy to install, also can ensure the borehole television shooting clear at work of popping one's head in simultaneously; Effectively practice thrift the engineering time, reduce construction risk.
Description of drawings
Accompanying drawing is a structural representation of the present invention
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail, see accompanying drawing.
The antifog protective device of borehole television probe is made up of outer tube connector 1, sealing ring 2, lamina septum pellucidum 3, diffuser 4, outer tube tailstock 8 and dehumidifying layer, and outer tube connector 1 is sealedly connected on diffuser 4 upper ends, and outer tube tailstock 8 is sealedly connected on diffuser 4 lower ends.
Described lamina septum pellucidum 3 is the dome shape; Have annular groove on the outside wall surface of lamina septum pellucidum 3; Be provided with sealing ring 2 in the groove; Lamina septum pellucidum 3 is fitted in the diffuser 4, and outer tube connector 1, diffuser 4, outer tube tailstock 8 form an enclosure space, relative seal cavity of formation between lamina septum pellucidum 3 and the outer tube connector 1.Lamina septum pellucidum 3 adopts glass material, and its effect is both can play buffer action, does not hinder the definition of image again; In diffuser 4 lower ends, be provided with the dehumidifying layer; The dehumidifying layer is positioned at outer tube tailstock 8 tops, and the dehumidifying layer is made up of loam cake 5, lower cover 7 and desiccant 6, and desiccant 6 is contained between loam cake 5 and the lower cover 7; Have equally distributed aperture on the loam cake 5, aperture can suck the aqueous vapor in the seal cavity in the desiccant.
Borehole television is popped one's head in use, and probe is to be contained in the separation layer top, and the lead of probe is drawn through outer tube connector 1; The camera lens of probe directly is placed on the separation layer 3; Coat suitable seal glue at the camera lens of probe and the joint portion of separation layer 3 then, the fog of separation layer 3 tops generation can not impact imaging results like this, and airtight space has guaranteed that also probe does not receive the influence of environment for use simultaneously; So just greatly reduce requirement (environment when for example the transportation of instrument and storage and construction are used) to environment for use; For the aqueous vapor in the confined space, can see through on the dehumidifying layer loam cake 5 agent 6 that is dried of equally distributed aperture and absorb, and then guarantee not haze in the diffuser 4; That the environment moisture that no matter uses has is much, the temperature difference has muchly, can guarantee the operate as normal of borehole television imaging system.
