A wind speed sensor for sponge city that is convenient for oil injection

Abstract

The invention discloses a sponge city wind speed sensor which is convenient for oil injection, which comprises a sensor main body and a rotational speed sensor. A rotational speed sensor is installed inside the sensor main body. A first bearing shell is fixedly installed inside, a first connecting bearing is fixedly installed inside the first bearing shell, and a second bearing shell is fixedly installed above the supporting shell. In the present invention, the oil inlet and the oil outlet installed on the piston cylinder are respectively connected to the oil tank, the first bearing shell and the second bearing shell through conduits, so that when the piston block moves back and forth inside the piston cylinder, the internal lubrication of the device can be achieved. The oil is twitched, so that the lubricating oil inside the oil tank is exchanged with the first bearing shell and the second bearing shell, effectively preventing the accumulation of impurities inside the lubricating oil, resulting in a decrease in the lubricating effect, thereby improving the working accuracy of the device.

Description

technical field [0001] The invention relates to the technical field of wind speed sensor equipment, in particular to a wind speed sensor for sponge cities that is convenient for oil filling. Background technique [0002] Sponge city is a new generation of urban stormwater management concept, which means that the city, like a sponge, has good elasticity in adapting to environmental changes and responding to natural disasters caused by rainwater, so it can also be called "water elasticity". City”, and in order to perfect the concept of sponge city, it is necessary to implement real-time monitoring of environmental changes such as precipitation and wind speed in the city, so as to understand the environmental changes in the city. Real-time monitoring of internal wind speed changes. [0003] The existing wind speed sensor used inside the sponge city usually drives the shaft to rotate by wind blowing the impeller, and the rotation is measured by the speed sensor, so as to analyz...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a wind speed sensor for sponge city that is convenient for oil filling, to solve the problem that the lubricating oil production time inside the current wind speed sensor for sponge city proposed in the above background technology is in a non-circulating state, resulting in poor lubricating effect of the lubricating oil , and the lubricating oil used for a long time accumulates together, which affects the smoothness of the rotation of the shaft, and the problem of inconvenient operation when the lubricating oil inside the sensor is replaced and added
