Description

Hydraulic roof snow removing device

Technical Field

The utility model relates to a technical field of snow removing instrument, concretely relates to fluid pressure type roof snow removing device.

Background

A large amount of accumulated snow is accumulated on roofs in winter in northern China often, if the snow is too large and is not melted or cleaned in time, the accumulated snow is accumulated more and more, water leakage of the roofs is easily caused, and the roofs with poor structural strength can be collapsed by the accumulated snow, so that life and property safety is threatened. Therefore, how to quickly clean the accumulated snow on the roof becomes a problem which needs to be solved urgently. At present, the following snow removing means are known:

1. manually snow sweeping: at present, the most extensive snow sweeping mode is still used in the north, the snow is scraped downwards by a simple rake manually, and the cost required by the method is the lowest. The method has the disadvantages of low snow clearing speed, untimely snow clearing and incomplete snow clearing, and in addition, the danger coefficient of personnel operating under the roof is high.

2. Wind-force snow sweeping device: the snow removing device removes snow through wind power, is suitable for snow to pile up relatively thin period, and the most snow can be blown away to powerful fan, and is faster than artifical snow removal in addition in the speed. The device has the disadvantages of relatively large mass and volume, complex structure, difficulty in troubleshooting after problems and high maintenance cost. And the temperature in northern China is low, the condition of frozen snow is easy to appear, and the wind power snow sweeping adaptability is relatively weak.

3. Adsorption type snow sweeping device: the device needs to be installed or placed on the roof of a house before work to realize subsequent work, and snow can be quickly swept away during work. The disadvantages are that the placing and taking-off is not easy, and the house is required to be placed on the roof all the time in the working process, so that the pressure on the roof is increased, and the house can be damaged more in the working process.

In summary, the three snow removing methods have various advantages and disadvantages, but the device for removing the frozen snow in the northern cold environment still needs to be designed reasonably.
