Abstract
The utility model relates to an anti-fog protection device of a borehole television probe, belonging to the field of the manufacture of engineering detection equipment. The anti-fog protection device of the borehole television probe is composed of an outer tube connector, a sealing ring, a transparent isolation layer, a light transmission cover, an outer tube tail seat and a dehumidifying layer, wherein the transparent isolation layer is mounted in the upper end of the light transmission cover in a pressing way; the dehumidifying layer is arranged at the lower end of the light transmission cover; an independent closed space is formed between the light transmission cover and the outer tube tail seat, so that fog is avoided being formed in the light transmission cover, and the fog produced due to temperature difference between the temperature above the ground and the temperature below the ground can be avoided; and meanwhile, the dehumidifying layer arranged on the outer tube tail seat can remove water vapor in the closed space to the maximum extent, so that the fog is reduced to the maximum extent. The anti-fog protection device of the borehole television probe is reasonable in design, simple in structure and convenient to mount and use, and is capable of guaranteeing clear shooting of the borehole television probe in work, effectively shortening the construction time and reducing the constriction risk at the same time.
Description
Technical field
The utility model relates to a kind of antifog protective device of borehole television probe, belongs 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 purpose of the utility model is to provide a kind of can prevent down effectively in working order and the borehole television probe protective device of handling the phenomenon that hazes automatically that 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 utility model 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; The antifog protective device of the utility model 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 the structural representation of the utility model
The specific embodiment
Below in conjunction with accompanying drawing the utility model 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.
