Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: gas relay and rain-proof cover of oil stream relay including rain-proof cover 1, the inner wall of rain-proof cover 1 is provided with fixed establishment 2. The number of the fixing mechanisms 2 is two groups and the fixing mechanisms are arranged at intervals in the transverse direction. The rear side inner wall fixed mounting of rain-proof cover 1 has servo motor 3, and servo motor 3's output shaft passes through shaft coupling fixedly connected with dwang 4, and rain-proof cover 1's top surface fixed connection has first spring 9 and second spring 10, the equal fixedly connected with buffer board 11 of one end of first spring 9 and second spring 10, and buffer board 11 is the slope setting.
When raining, the rainwater falls on the top surface of the buffer plate 11, the impact force of the rainwater drives the buffer plate 11 to move downwards, the elastic force of the first spring 9 rebounds the impact force of the rainwater, the impact force of the rainwater can be buffered, the vibration generated due to rainwater impact is reduced, and the safety of the operation of the whole equipment is improved.
The fixing mechanism 2 comprises a connecting plate 201, a sliding rod sleeve 202, a gear rod 203 and a gear 204, the sliding rod sleeve 202 is fixedly connected to the inner wall of the rear side of the rain cover 1, the gear rod 203 is slidably mounted inside the sliding rod sleeve 202, the gear 204 is fixedly connected to one end of the rotating rod 4, the gear rods 203 of the two sets of fixing mechanisms 2 are respectively arranged on the upper side and the lower side of the gear 204, and the gear 204 is meshed with the two sets of gear rods 203. Spout 5 has been seted up at the inboard top of rain-proof cover 1, and the inside slidable mounting of spout 5 has slider 6, and the bottom surface of slider 6 is connected with the top surface fixed connection of connecting plate 201 to make connecting plate 201 and rain-proof cover 1 slidable mounting. The outer wall of one side of the connecting plate 201 is fixedly connected with one end of the gear rod 203.
The ventilation hole 7 has been seted up on the connecting plate 201, and vent 12 has all been seted up to the both sides of rain-proof cover 1, can guarantee the inside ventilation of distributor, prevents inside part that the heat is too high under sealed condition and damages the part of relay.
