Referring to fig. 1 to 11, the invention provides an outdoor cable branch box capable of performing corresponding early warning processing in time when the desiccant particles 409 used for drying the interior of the box door 2 are agglomerated, so that workers can find out that the desiccant agglomerates used for dehumidification and drying in the branch box are invalid in time and replace the desiccant agglomerates, normal operation of the outdoor cable branch box can be guaranteed, the service life of the outdoor branch box is prolonged, and the use safety of the outdoor cable branch box is improved.
When the box door 2 is closed and in a closed state, the small air pump 402 continuously pumps the air inside the box door 2 into the end pipe 401 connected with the small air pump 402, then the air flows into the transverse conduit 400 through the buckle ring 405 buckled in the end pipe 401, the air inside the box door 2 is introduced into the transverse conduit 400 through the small air pump 402, moisture mixed in the air is absorbed by the desiccant particles 409 in the transverse conduit 400, and the dried and dehumidified air is discharged by the other end pipe 401 communicated with the other end of the transverse conduit 400, so that active circulation drying and dehumidifying treatment of the moisture inside the box door 2 is realized, compared with the traditional mode of passively dehumidifying and drying by placing a desiccant in a breathable container, the dehumidifying and drying device can realize better dehumidifying and drying effects and high dehumidifying and drying efficiency on the inside of the box door 2.
When the desiccant granules 409 filled in the transverse duct 400 between the two end tubes 401 are agglomerated and failed, airflow is difficult to flow out of the transverse duct 400, so that the air pressure inside the end tube 401 connected with the small air pump 402 is increased, then most of the air introduced by the small air pump 402 flows into the longitudinal piston cylinder 300 through the long hose 304, so that the air pressure inside the longitudinal piston cylinder 300 is increased, and then the sealing piston 305 drives the pointing arrow 303 to move upwards through the piston core rod 301, so that the pointing arrow 303 points to the warning scale marked on the side wall of the longitudinal piston cylinder 300 and can play a role in timely reminding a worker that the desiccant granules 409 filled in the transverse duct 400 between the two end tubes 401 are agglomerated and failed. When the caking of the desiccant granules 409 filled in the transverse conduit 400 between the two end pipes 401 is failed, a worker pulls the longitudinal piston cylinder 300 upwards to enable the longitudinal piston cylinder 300 to drive the wedge block 309 to move upwards through the transverse cylinder 307, when the inclined surface of the wedge block 309 contacts the side seat 404 connected to the side wall of the transverse conduit 400 above the transverse conduit 400, the wedge block 309 retracts towards the transverse cylinder 307, when the bottom surface of the wedge block 309 is above the side seat 404, the wedge block 309 is ejected again under the elastic force of the return spring a310, the worker pulls the longitudinal piston cylinder 300 downwards to enable the transverse conduit 400 filled with new desiccant granules 409 to gradually move between the two end pipes 401, during the downward movement of the transverse conduit 400, the annular chamfer 406 on the end of the snap ring 405 firstly contacts the end pipe 401 and enables the snap ring 405 to gradually move towards the annular recess, when the transverse conduit 400 moves between the two end pipes 401, the snap ring 410C is snapped to the end pipe 401, the snap ring 405 is quickly replaced corresponding to the end pipe 401, and the moisture absorption of the desiccant granules 401 can be quickly, and the moisture absorption of the desiccant granules of the desiccant box door 400 can be quickly reduced again.
Under the effect of the elastic force of the spring, the arc limiting head 502 extending out of the transverse groove can limit the transverse guide pipe 400 above the arc limiting head, so that each transverse guide pipe 400 is limited to slide downwards, and when a worker does not drive the transverse guide pipe 400 to move up and down through the longitudinal piston cylinder 300, the transverse guide pipe 400 filled with the desiccant particles 409 can be stably fixed.
