Example 1

Referring to fig. 1, 2, 3 and 4, the embodiment provides a defogging device for a borehole television probe, which includes a tubular spray body 1, where the spray body 1 is of a hollow structure to enable the spray body 1 to be sleeved on the borehole television probe, an annular distribution channel 2 is disposed in a tube wall of the spray body 1, a main channel 3 and a plurality of sub channels 4 coaxial with the spray body 1 are respectively disposed in the tube walls of the spray body 1 at two sides of the distribution channel 2, and referring to fig. 3, the preferred embodiment is five, the main channel 3 is used for inflow of antifogging sprays, the sub channels 4 are used for outflow of antifogging sprays, the main channel 3 is communicated with the sub channels 4 through the distribution channel 2, and nozzles 5 are disposed at outlets of the sub channels 4, so that, when in actual use, the antifogging sprays enter from the main channel 3 and are distributed into each sub channel 4 through the distribution channel 2, finally, the mist is sprayed out from a nozzle 5 arranged at the outlet of the secondary channel 4 to the borehole television probe for demisting.

Referring to fig. 1, fig. 2 and fig. 3, in order to facilitate fixing of the spray body 1 and increase the application range of the spraying apparatus at the same time, in a further preferred embodiment, an opening 6 penetrating through the spray body 1 is formed in the spray body 1, a connecting plate 7 is arranged on an inner wall of the opening 6, connecting holes 9 for fasteners 8 to pass through are correspondingly formed in the two connecting plates 7, the two connecting plates 7 are connected through the fasteners 8, and after the spray body 1 is sleeved on a drill television probe, the spray body 1 is fixed on the drill television probe through the fasteners 8, so that the operation is simple and the fixing is firm; meanwhile, the spraying body 1 has certain elasticity, so that the spraying body can be used for drilling television probes of various types, and it is worth explaining that the length of the connecting plate 7 and the number of the connecting holes 9 can be determined according to the actual size of the spraying body 1 so as to achieve the optimal fixing effect.

With reference to fig. 4, a further preferred embodiment provides that, in order to allow the anti-fogging spray flowing in from the main channel 3 to flow out from the inlet of the main channel 3, a one-way valve 10 is arranged in said main channel 3, so that the anti-fogging spray can only flow in from the main channel 3 and not out from the main channel 3.

Referring to fig. 3 and 4, in a further preferred embodiment, in order to make defogging more uniform, a plurality of the secondary channels 4 are uniformly distributed in the tube wall of the spray body 1, and in order to improve defogging effect, the outlet end of the nozzle 5 is oblique to the axial lead of the spray body 1, so that the antifogging spray sprayed from the nozzle 5 can be sprayed on the borehole tv probe at a certain angle, wherein the included angle between the nozzle 5 and the axial lead of the spray body 1 is preferably 45 °.
