Background
In the daily switching operation process of a transformer substation, a motor drives a transmission connecting rod of a mechanism box to perform transverse or longitudinal displacement, and a hole of the transmission connecting rod of the mechanism box needs to be sealed in practical application, so that foreign matters can not enter the mechanism box under various outdoor conditions, equipment accidents such as equipment tripping, alternating current and direct current grounding, protection failure and the like caused by the fact that the foreign matters enter the equipment are avoided, and the hole at the position of the connecting rod can not be sealed by a solidified sealing material due to the action characteristic of the transmission connecting rod, so that in the prior art, a traditional rubber sealing ring is generally adopted as a sealing device. However, the conventional rubber sealing ring has the following disadvantages: the first is that the running of the transmission connecting rod is added with extra resistance, the second is that the aging and damage phenomena can occur along with the increase of the running years of the equipment, the entering of foreign matters such as rainwater, dust, small animals and the like can not be prevented, if the foreign matters are not processed in time, the power supply reliability of a power grid is inevitably influenced, even an electric power accident is caused, and before a new rubber sealing ring is replaced, rubber attached to the hole of the transmission connecting rod of the mechanism box is remained before the rubber sealing ring is required to be cleaned, so that the operation is very troublesome.
Therefore, there is a need for a new hole sealing device that can be used for a long time and is easy to replace, so as to meet the special requirements of the sealing device at the hole dense position of the box-forming transmission connecting rod.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a mechanism case transmission connecting rod hole sealing device can use for a long time, is convenient for change, can not increase extra resistance to the transmission connecting rod when playing good sealed effect.
The purpose of the utility model is realized through the following technical scheme:
the utility model provides a mechanism case transmission connecting rod hole sealing device, is equipped with annular dustproof sealing strip including installing the rain-proof cover in mechanism case transmission connecting rod hole top in the rain-proof cover, is equipped with the dustproof brush of in close contact and the terminal circle that forms the same with the transmission connecting rod diameter of dustproof brush on the dustproof sealing strip inner ring face, still is equipped with the fixed establishment that is used for fixing dustproof sealing strip on the mechanism case in the rain-proof cover.
Further, rain-proof cover is stainless steel, and the tip welding of rain-proof cover and mechanism case contact has the arc connection piece of threaded through-hole, and rain-proof cover passes through arc connection piece and mechanism case threaded connection.
Furthermore, a sealing washer is arranged between the arc-shaped connecting sheet and the mechanism box, and a through hole corresponding to the threaded hole of the mechanism box is formed in the sealing washer.
Furthermore, the dustproof brush is a nylon dustproof brush.
Furthermore, two dustproof sealing strips are arranged in the rainproof cover.
Further, fixed establishment is stainless steel's solid fixed ring, and solid fixed ring's outer lane is opened has a plurality of arc breachs that correspond with mechanism's case screw hole, and solid fixed ring's diameter is greater than the diameter of dust sealing strip.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model can effectively prevent rainwater and dust falling downwards, and the nylon dustproof brush on the dustproof sealing strip is in close contact, so that the utility model can effectively prevent dust and small animals from entering the hole of the transmission connecting rod of the mechanism box; the nylon dustproof brush is not easy to age, the service life is stably maintained to be more than 13 years, the nylon dustproof brush has obvious advantages compared with the traditional rubber sealing ring which can be used for 6 years at most, and the nylon dustproof brush is soft and strong in toughness and cannot block the telescopic movement of the transmission connecting rod; because the dustproof sealing strip and the nylon dustproof brush are not attached to the holes of the mechanism box after long-term use, the residues are not required to be cleaned during replacement, and only the fixing mechanism is directly disassembled for replacement, so that the replacement is convenient; the utility model discloses simple structure, low in manufacturing cost can install under the circumstances of not having a power failure, and economy and social are showing, have very big popularization and application and worth.
Further, the bolt can pass through the breach of solid fixed ring outer lane and the screw hole of screw in mechanism case is fixed with the fixed ring, realizes fixed to dust sealing strip, and the design of the breach of solid fixed ring outer lane can make dust sealing strip's diameter bigger as far as, plays better sealed effect.
