The utility model has the advantages that the waterproof performance of the top output operating mechanism is improved, and the top surface of the mechanism has no gap; prevent that the rainwater that leads to because the sealing washer damages from following inside mechanism output shaft gets into the mechanism to improve top output mechanism's waterproof capability.
Description
Technical Field
The utility model relates to the technical field of power supply systems, in particular to a waterproof joint assembly suitable for a top output operating mechanism.
Background
The isolating switch is one of the core devices of the power supply system and plays a very important role in the power plant and the electrified railway system at present. The high-voltage power distribution device has the main effects that when electrical equipment is overhauled, the part which needs to be powered off in the high-voltage power distribution device is reliably isolated from the electrified part, and an obvious disconnection point is formed, so that the safety of personnel in overhauling work is ensured. If the mechanism box is water-in, the operation mechanism can be refused or malfunction, and particularly, the infiltration of a large amount of rainwater in rainy season affects the maintenance and even the driving safety.
Disclosure of Invention
The utility model aims to provide a waterproof joint assembly suitable for a top output operating mechanism, wherein the lower part of a waterproof joint is connected with an output shaft of the operating mechanism, a joint waterproof sealing ring fills a gap between the lower part of the waterproof joint and an output hole of the operating mechanism, and a nylon flat gasket fills the gap between the lower part of the waterproof joint and the top part of a box of the operating mechanism, so that the top of the mechanism is waterproof.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the waterproof joint assembly is arranged at an output shaft at the top of the top output operating mechanism, the lower part of the waterproof joint is matched with the output shaft through a key slot and a flat key to realize transmission, and the upper part of the waterproof joint is connected with the lower part of the waterproof joint through welding, so that an output port of the output shaft which is already arranged in the mechanism is sealed, and rainwater is prevented from entering the mechanism along a transmission rod and the output shaft; the output shaft and the mechanism output port are sealed by using the joint waterproof sealing ring, the waterproof joint and the mechanism box are prevented from being worn by using the nylon Long Pingdian to be installed between the bottom of the waterproof joint and the mechanism box, and the waterproof capability is further improved.
The utility model has the beneficial effects that: the novel waterproof joint assembly can more effectively prevent rainwater from penetrating into the mechanism along the output shaft, greatly improves the waterproof performance of the top output operating mechanism in summer with multiple rainwater, and can solve the possibility of water leakage due to failure of the sealing ring.

Detailed Description
The construction of the waterproof joint assembly for a top output operation mechanism of the present utility model will be described with reference to the accompanying drawings.
As shown in fig. 1 to 3, the waterproof joint assembly for a top output operation mechanism of the present utility model includes: the waterproof connector comprises a waterproof connector upper part, a waterproof connector lower part, a switching-on/switching-off label, a nylon flat pad, a connector waterproof sealing ring and an inner hexagon set screw; the waterproof joint component is matched with the mechanism output shaft through a flat key and fixed through an inner hexagonal set screw, and waterproof performance is enhanced by using a nylon flat pad and a joint waterproof sealing ring; the waterproof connector is assembled with the waterproof machine head in a welding mode, and the waterproof connector can be selected according to specific project requirements.
When the waterproof joint assembly is assembled with the top output operation mechanism, the key groove in the waterproof joint is connected with the mechanism output shaft through the flat key, so that the accuracy of the mechanism output angle is ensured; the waterproof sealing ring of the inner joint of the waterproof joint ensures that rainwater cannot infiltrate into the mechanism from the bottom of the joint; the nylon flat pad at the bottom of the waterproof joint assembly plays a role in canceling gaps between the waterproof joint assembly and the top of the mechanism, and can prevent the waterproof joint assembly from being worn out in contact with the top of the mechanism box, so that the waterproof performance of the top output operating mechanism is improved.
The lower part of the waterproof joint is fixed with the mechanism output shaft through an inner hexagonal set screw; the lower part of the waterproof joint is fixed with a flat key on the mechanism output shaft through an internal key slot to realize synchronous rotation; the nylon flat pad and the joint waterproof sealing ring are arranged on the output shaft hole.
Fig. 2 shows a waterproof joint assembly for a top output operating mechanism when the top output mechanism is used for matching with a horizontally opened isolating switch, and the joint can be connected with a transmission rod or a transmission rod joint assembly to drive the isolating switch to switch on and switch off, and realize sealing of an output hole of the top output mechanism.
When the top output mechanism is used for matching with the vertical opening isolating switch, the vertical conversion mechanism is required to be additionally arranged on the mechanism, and a waterproof joint assembly of the top output operating mechanism shown in fig. 3 is required to be used at the moment.
