Description
Technical Field
The invention relates to the technical field of new energy, in particular to an ice breaking and wind collecting mechanism for a vertical axis wind power generation device.
Background
With the global climate and energy issues becoming more prominent, wind power has become a new source of attention worldwide. The wind energy is a green renewable new energy source, has huge energy, is widely distributed, can be taken on site, does not need transportation, and is convenient to use. The utilization of wind energy has been developed from the first wind lifting, sail sailing and wind mill flour to today's wind power generation.
With the innovative development of low wind speed technology, low wind speed areas which previously had no development value are becoming hot soil for the wind power industry. At present, the reserves of wind resources with wind speeds of more than 5m/s and reaching economic development values in the central east and south regions are close to 9 hundred million KW. And in order to have economic development value in a low wind speed area, the wind energy density acting on the wind wheel blade must reach 0.08-0.17 kw/m 2. However, the annual average wind speed in the central east and south regions of China is 5.0-6.5m/s, that is, the wind energy density is lower than 0.08kw/m2, which cannot be directly utilized.
Based on the background, through research in recent years, the structure of the wind collector is further improved, except for the original flow guide rib plate, a variable pitch air door is additionally arranged in the structure, and the variable pitch air door and the airflow guide blade in the original special patent form the wind collector together or independently, so that the wind energy density entering the wind power generation device is improved, and the low-density wind energy in a low wind speed area is improved. In addition, the improved wind collector device is provided with a variable pitch air door with a variable pitch function, so that the power of the vertical axis wind power generation device is adjusted, the vertical axis wind power generation device is closed in extreme storm weather, and the internal structure of the power generation device is protected. Thus, the variable-pitch wind collecting mechanism for the vertical-axis wind power generation device is formed. However, the improved wind collecting structure with the pitch control function has a big problem that in low-temperature days below zero, the temperature of the airflow flowing out of the wind collecting structure is low, which brings a serious problem to the vertical axis wind power generation device. In addition, because the temperature of the wind flow is relatively low, an ice layer is generated on the side wall in the tapered channel of the vertical shaft, if the wind flow is in snow, snow flakes are brought into the tapered channel, and because the snow has certain viscosity, the snow flakes can form the snow layer on the side wall, if the ice and the snow are accumulated in the wind channel, the flow of the wind flow can be influenced, the energy density of the wind flow is reduced, and if the ice and the snow are accumulated on the movable blade rotor, the dynamic balance of the vertical shaft wind power generation rotor can be influenced. Thus, the pitch wind collecting structure must have the performance of ice breaking.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
An embodiment of the present invention provides an ice-breaking wind-collecting mechanism, mainly for a wind power generation device perpendicular to an axis, as shown in fig. 1, 2 and 3, the ice-breaking wind-collecting mechanism includes: the device comprises an upper end plate connecting plate 2, a lower end plate connecting plate 3, hot air injection pipes 12, injection pipe supports 13 and a plurality of ice breaking and air collecting mechanism side plates 1; a plurality of broken ice collection wind mechanism curb plate 1 is annular interval installation in proper order and is between upper end plate connecting plate 2 and lower end plate connecting plate 3, and adjacent broken ice collection wind mechanism curb plate 1 forms the tapered passageway with upper end plate connecting plate 2 and lower end plate connecting plate 3. The hot air injection pipe 12 is installed in the tapered passage by the injection pipe holder 13.
The hot air injection pipe 12 can be a seamless steel pipe, a plurality of injection holes with the diameter of 3mm-10mm are formed in the hot air injection pipe, hot air from the side plate 1 of the ice breaking and air collecting mechanism is mixed with incoming wind flow, the temperature of the incoming wind flow is increased to be above zero by 3-5 ℃, icing and accumulated snow on a downstream variable pitch air door, a guide vane stator and a moving blade rotor can be eliminated, and the safe and economical operation of the vertical axis wind power generation device is ensured. The hot air spray pipes are arranged along the height of the wind collecting structure so as to be uniformly mixed with the incoming wind.
Generally, sand dust is mixed in wind, raindrops are mixed in rainy days, and if the sand dust and the raindrops are not removed, the sand dust and the raindrops enter a movable blade rotor and impact on the movable blade to generate a hammering phenomenon, so that the movable blade is seriously eroded, and the service life of the whole unit is influenced. Therefore, the side plates 1 of the ice-breaking wind-collecting mechanism are all made into cambered surfaces. The side plates 1 of the ice-breaking wind-collecting mechanism are installed between the upper end plate connecting plate 2 and the lower end plate connecting plate 3 in an arc shape, and the adjacent side plates 1 of the ice-breaking wind-collecting mechanism, the upper end plate connecting plate 2 and the lower end plate connecting plate 3 form a curved annular tapered channel. Have sand and dust and raindrop entering collection wind channel, produced centrifugal force, got rid of sand and dust and raindrop and formed a rete to the intrados of broken ice collection wind mechanism curb plate 1 on, reached certain degree when the thickness of membrane, the membrane moves down to lower extreme board connecting plate 3 on under the action of gravity, lower extreme board connecting plate 3 inclines a little from inside to outside, and the rainwater can flow to the outside of vertical axis fan. When the dust is accumulated, the dust can be removed by a special dust suction pipe or cleaned manually. The wind energy density is improved by the incoming wind through the tapered channel, so that the vertical axis wind power generation device can obtain high wind current energy density in a low wind speed area, and the adaptability, the availability, the economy and the safety of the vertical axis wind power generation device in the low wind speed area are improved. In addition, when sand dust or raindrops enter the tapered channel, centrifugal force is generated, the sand dust or the raindrops are thrown onto the side plate 1 of the ice breaking and wind collecting mechanism and are separated and removed, and the erosion effect on the rotor movable blades is reduced.

The mode of improving the energy density of the wind flow by wind collection cannot be realized by a three-blade horizontal shaft wind power generation device.
Because the wind power generation device (including a vertical axis wind power generator and a horizontal axis wind power generator) has the problem of icing and snow accumulation in cold regions, if the problem is not solved, the safe operation of the wind power generation device is influenced, and the effective power of the wind power generation device is influenced.
