1one

Изобретение относитс к измерительной технике и может быть использовано в метеорологии дл измерени скорости ветра в полевых услови х при жестких ограничени х на размеры и массу анемометра.The invention relates to a measurement technique and can be used in meteorology for measuring wind speed in field conditions with severe restrictions on the size and mass of the anemometer.

Известны анемометры, содержащие ша- 5 ровой ветроприемник, укрепленный иа стержне или нити, отклонение которого от отвесного положени под действием ветра отсчитываетс по шкале, нанесенной на диск, расположенный под шаром 1.,QAnemometers are known that contain a ballroom wind receiver, fortified with a rod or thread, the deviation of which from the plumb position under the action of the wind is measured on a scale applied to the disk located under the ball 1. Q

Наиболее близким по технической сушности и достигаемому результату к изобретению вл етс анемометр, содержащий сферический приемник ветрового давлени , основание и противовес, выполненный в виде двух концентрических сфер, укрепленных 15 на той же штанге, что и приемник. Штанга оканчиваетс подп тником, опирающимс на опору, закрепленную в основании 2.The closest in technical drying and the achieved result to the invention is an anemometer containing a spherical wind pressure receiver, a base and a counterweight, made in the form of two concentric spheres, fortified 15 on the same rod as the receiver. The rod ends with a bushing resting on a support fixed in the base 2.

Недостатком известной конструкции вл ютс значительные габариты, не позво- 2о л ющие использовать прибор в полевых услови х , при жестких ограничени х по массе и габаритам прибора.A disadvantage of the known construction is the considerable dimensions that do not allow using the device in field conditions, with severe limitations on the weight and dimensions of the device.

Цель изобретени - упрощение конструкции и уменьшение габаритов.The purpose of the invention is to simplify the design and reduce the size.

Дл достижени указанной цели в анемометре , содержащем сферический приемник ветрового давлени с противовесом и основание, сферический приемник ветрового давлени с противовесом выполнен из двух полусфер разной плотности и установлен с возможностью свободного перекатывани по основанию, снабженному концентрическими окружност ми и расположенным в их центре выступом, центрирующим коническое углубление, выполненное в полусфере большей плотности сферического приемника ветрового давлени на его оси симметрии.To achieve this goal, in the anemometer containing a spherical wind pressure receiver with a counterweight and a base, the spherical wind pressure receiver with a counterweight is made of two hemispheres of different density and mounted with the possibility of free rolling on the base, provided with concentric circles and located in the center of the protrusion centering a conical depression made in a hemisphere of higher density of a spherical wind pressure receiver on its axis of symmetry.

Claims

The anemometer consists of a spherical wind pressure receiver composed of two hemispheres — a hollow 1 and a solid 2, as well as a base 3. On the solid hemisphere 2 of the receiver there is a conical recess 4, and on the base 3 there is a corresponding conical protrusion 5. The spherical level 6 is fixed on The base 3, on the surface of which is concentric with respect to the centering protrusion 5, is applied around the circumference 7 of the instrument scale, a lifting screw (not shown) is screwed into the base. The anemometer works as follows. Prior to measurement, the pressure receiver is mounted on base 3, centered by recess 4 on protrusion 5, then base 3 on level 6 is set using a lifting screw horizontally and on the point of contact of the receiver and base are read using a scale consisting of circles 7. The wind speed is from 0 to 10 m / s. The anemometer has a sphere diameter of 50 mm, a wall thickness of a hollow hemisphere is 13 mm, the material of the wind pressure receiver is steel. Starting from the basic equilibrium equation of the pressure receiver under the action of the moments of the tilting force of the wind pressure and the force of gravity of the receiver P, which at the eccentricity of the center of mass E acts on the arm a, and the chosen design parameters, it is possible to construct a scale consisting of two concentric circles A: for wind speed 5, the diameter of a circle is 10 mm, for a wind speed of 10 m / s, the diameter of a circle is 65 mm. The use of the proposed anemometer will make it possible to measure wind speed when performing geodetic, construction, and exploration work, when restrictions are imposed on the size, mass, and complexity of the equipment. Claims An anemometer containing a spherical wind pressure receiver with a counterweight and a base, characterized in that, in order to simplify the design and reduce the size, the spherical wind pressure receiver with a counterweight is made of two hemispheres of different density and installed with the possibility of free rolling on the base, equipped with concentric circles and a protrusion located in their center centering a conical depression made in a hemisphere of higher density spherical receiver and wind pressure on its axis of symmetry.
