Description

The novel wind-speed measuring instrument

Technical field:

The utility model relates to the measuring wind technical field, can be widely used on various cross-ventilation technical fields and the device, and be a kind of novel wind-speed measuring instrument specifically.

Background technology:

At present, on the measuring wind appliance arrangement, also do not find method preferably.Existing method is measured as range estimation or through alternate manner and is converted and can obtain a result, and these methods show as out of true and not directly perceived, thus there are many weak points such as not energy-conservation, so be necessary to further investigate in this respect.

Summary of the invention:

The purpose of this utility model is: a kind of novel wind-speed measuring instrument is provided.When wind speed is big more, the metal slide block moves right, swept resistance is more little, the reometer reading is big more, can on reometer, directly read wind speed through mensuration with after converting, moreover also can directly read wind speed by the scale of the pointer indication on the deep bead, the work of survey wind speed is become intuitively, thereby reach the purpose of this utility model.

The technical scheme that its technical matters that solves the utility model adopts is: the utility model is made up of swept resistance sheet, plastic casing, fixing metal bar, balance sheet metal, spring, weathervane lock screw, weathervane, power supply, reometer, binding post, bedplate, rolling bearing, metal slip contact, lead, deep bead, metal slide block, rolling bearing is fixedlyed connected with bedplate, fixing metal bar, balance sheet metal, metal slip contact, spring are connected in the plastic casing, weathervane is connected with the weathervane lock screw, and spring is connected with the metal slide block.Described spring and metal slide block and fixing metal bar are slidingly connected, and the swept resistance sheet is arranged at the bottom; Described spring, the fixing metal bar, the metal slide block, metal slip contact, swept resistance sheet and lead, power supply, reometer connects into current return.

Generally just this device weathervane can make the deep bead can both be over against wind direction when any wind direction, when wind speed is big more, the metal slide block moves right, swept resistance is more little, the reometer reading is big more, can on reometer, directly read wind speed through mensuration with after converting, moreover also can directly read air speed value by the calibration data of the pointer indication on the swept resistance sheet.

The beneficial effects of the utility model are: a kind of novel wind-speed measuring instrument is provided, when wind speed is big more, the metal slide block moves right, swept resistance is more little, the reometer reading is big more, can on reometer, directly read wind speed through mensuration with after converting, moreover also can directly read wind speed, make the work of survey wind speed become directly perceived by the scale of the pointer indication on the deep bead.

Fig. 1 is the wherein structural representation sketch of a form of the utility model.

Fig. 2 is Fig. 1 one cross-section structure simplified schematic diagram.

Fig. 3 is that tuning drive gear amplifies simplified schematic diagram above the utility model plastic casing.

As shown in the figure: 1 expression swept resistance sheet, 2 expression plastic casings, 3 expression fixing metal bars, 4 expression balance sheet metals, 5 expression springs, 6 expression weathervane lock screws, 7 expression weathervanes, 8 expression power supplys, 9 expression leads, 10 expression reometers, 11 expression binding posts, 12 expression bedplates, 13 expression rolling bearings, 14 expression metal slip contacts, 15 expression rules, 16 expression deep beads, 17 expression metal slide blocks, 18 expression pointers.

Embodiment:

The utility model is by swept resistance sheet 1, plastic casing 2, fixing metal bar 3, balance sheet metal 4, spring 5, weathervane lock screw 6, weathervane 7, power supply 8, lead 9, reometer 10, binding post 11, bedplate 12, rolling bearing 13, metal slip contact 14, rule 15, deep bead 16, metal slide block 17, pointer 18 is formed, and rolling bearing 13 is fixedlyed connected with bedplate 12, fixing metal bar 3, balance sheet metal 4, metal slip contact 14, spring 5 are connected in the plastic casing 2, weathervane 7 is connected with weathervane lock screw 6, and spring 5 is connected with metal slide block 17; Described spring 5 and metal slide block 17 are slidingly connected with fixing metal bar 3, and swept resistance sheet 1 is arranged at the bottom; Described spring 5, fixing metal bar 3, metal slide block 17, metal slip contact 14, swept resistance sheet 1 and lead 9, power supply 8, reometer 10 connects into current return.

This device weathervane can make the deep bead can both be over against wind direction when any wind direction, when wind speed is big more, the metal slide block moves right, the swept resistance value is more little, the reometer reading is big more, can on reometer, directly read wind speed through mensuration with after converting, moreover the scale of the pointer indication that also can pull by keeping out the wind is directly read air speed value.
