Abstract
The invention relates to electric machines, specifically to the design of a linear electric generator, which can be used, for example, for converting the energy from water, in particular waves, or the energy from weak and moderate winds into electrical energy. The linear electric generator comprises a housing, in which there are arranged coaxially: a rotor and a stator, with the possibility of the relative translational motion thereof along one axis, which rotor and stator are intended for kinematic connection to the drive of the generator. Furthermore, the stator is manufactured in the form of a winding, which surrounds the rotor with a group of permanent magnets, while the terminals of the stator are intended for connection of a load thereto. In accordance with the invention, the linear electric generator is in the form of a two-piston hydraulic system, in which a cavity in the housing with the stator and the rotor is filled with mineral oil with a high degree of purity and a low level of viscosity, for example transformer oil. The stator is manufactured in the form of a tubular piston from a nonmagnetic material with a three-phase winding fixed thereto and a magnetic contactor, which is formed by a spiral winding consisting of a soft-magnetic wire and a supporting element. The rotor is manufactured in the form a tubular piston from nonmagnetic material with a group of permanent magnets arranged thereon on the outside, which permanent magnets are provided with pole concentrators and two rods mounted coaxially with the rotor at opposite ends of the tubular piston, which rods are intended for kinematic connection thereof to the drive of the generator, while the tubular pistons of the stator and the rotor are fixed to tension springs, which are mounted between the housing and the ends, respectively, of the tubular pistons of the stator and the rotor with the possibility of the oscillation of the latter in phase opposition to one another. The linear electric generator solves the problem of the use thereof for converting energy from water, in particular waves, or the energy from weak and moderate winds into electrical energy. The proposed problem is solved by virtue of providing conditions for the use of a liquid which fills the cavity in the housing of the generator as a structural element of the linear electric generator. Owing to the fact that the liquid is practically incompressible, in the proposed device the simultaneous movement of the stator and the rotor in the liquid in opposite directions is ensured without the use of additional complex mechanisms being required to achieve this.
Description
Линейный электрогенератор. Предлагаемое изобретение относится к электрическим машинам, а именно к конструкции линейного электрогенератора, который может быть использован, например, для преобразования в электрическую энергию энергии воды, в частности волн, или энергии слабых и умеренных ветров. Linear electric generator. The present invention relates to electric machines, and in particular to the design of a linear electric generator, which can be used, for example, to convert water energy, in particular waves, or the energy of weak and moderate winds into electric energy.
Наиболее близким к предлагаемому по количеству существенных признаков является линейный электрогенератор, содержащий корпус, в котором соосно размещены ротор и статор, с возможностью их относительного поступательного перемещения вдоль одной оси и предназначенные для их кинематического соединения с приводом генератора, при этом статор изготовлен в виде обмотки, которая охватывает ротор с группой постоянных магнитов, а выводы статора предназначены для подключения к ним нагрузки [Патент РФ N° 2334340 на изобретение, МПК (2006.01) Н02К7/18; Н02К35/02; Е21В47/022; опубл. 20.09.2008 г.]. Closest to the proposed one by the number of essential features is a linear electric generator containing a housing in which the rotor and stator are coaxially placed, with the possibility of their relative translational movement along one axis and intended for their kinematic connection with the generator drive, while the stator is made in the form of a winding, which covers the rotor with a group of permanent magnets, and the stator leads are designed to connect loads to them [RF Patent N ° 2334340 for invention, IPC (2006.01) Н02К7 / 18; H02K35 / 02; E21B47 / 022; publ. September 20, 2008].
Описанный генератор предназначен для питания скважинной аппаратуры и требует для своей работы значительной амплитуды и частоты колебаний ротора относительно статора (или наоборот) для производства электроэнергии достаточной для работы аппаратуры, поэтому он не может быть использован, например, для преобразования энергии воды, в частности волн или энергии слабых и умеренных ветров в электрическую энергию. The described generator is designed to power the downhole equipment and requires for its operation a significant amplitude and frequency of oscillation of the rotor relative to the stator (or vice versa) for the production of electricity sufficient for the equipment to work, therefore it cannot be used, for example, to convert water energy, in particular waves or the energy of weak and moderate winds into electrical energy.
Кроме сказанного, силовой элемент указанного генератора изготовлен в виде сильфона из материала с памятью формы и установлен в герметичной полости внутри статора, к которому подведены провода от обмотки возбуждения через коммутатор, к которому, в свою очередь, подключен источник питания и накопитель электроэнергии, а поэтому описанный генератор имеет значительную себестоимость. In addition, the power element of the specified generator is made in the form of a bellows from a material with shape memory and installed in a sealed cavity inside the stator, to which wires from the field winding are connected through a switch, to which, in turn, a power source and an energy storage device are connected, and therefore the described generator has a significant cost.
Учитывая изложенное, в основу предлагаемого изобретения поставлена задача создания такого линейного генератора, который можно было бы использовать для преобразования энергии воды, в частности волн, или энергии слабых и умеренных ветров в электрическую энергию, который при этом имел бы меньшую себестоимость чем генератор-прототип.
Поставленная задача решается за счет создания условий для использования в качестве конструктивного элемента генератора жидкость, которой заполняют полость корпуса генератора. Благодаря тому, что жидкость является практически несжимаемой, в предлагаемом устройстве обеспечивается одновременное движение в жидкости в противоположных направлениях статора и ротора, для осуществления которого не требуется применение дополнительных сложных механизмов. Given the foregoing, the present invention is based on the task of creating such a linear generator that could be used to convert the energy of water, in particular waves, or the energy of weak and moderate winds into electrical energy, which would have a lower cost than the prototype generator. The problem is solved by creating conditions for use as a structural element of the generator fluid, which fill the cavity of the generator housing. Due to the fact that the liquid is practically incompressible, the proposed device provides simultaneous movement in the liquid in opposite directions of the stator and rotor, which does not require the use of additional complex mechanisms.
Предлагаемый, как и известный, линейный электрогенератор, содержит корпус, в котором соосно размещены ротор и статор, с возможностью их относительного поступательного перемещения вдоль одной оси и предназначенные для их кинематического соединения с приводом генератора. При этом статор изготовлен в виде обмотки, которая охватывает ротор с группой постоянных магнитов, а выводы статора предназначены для подключения к ним нагрузки, а, согласно изобретению, линейный генератор выполнен в виде двухпоршневой гидравлической системы, в которой полость корпуса со статором и ротором заполнена минеральным маслом высокой чистоты и низкой вязкости, например, трансформаторным маслом. Статор изготовлен в виде трубчатого поршня из немагнитного материала с закрепленной на нем трехфазной обмоткой и магнитного замыкателя, выполненного спиральной намоткой из магнитомягкой проволоки и несущего элемента. Ротор изготовлен в виде трубчатого поршня из немагнитного материала с группой размещенных на нем снаружи постоянных магнитов, обеспеченных полюсными концентраторами и двумя, установленными соосно с ротором на противоположных торцах трубчатого поршня ротора, штоками, предназначенными для их кинематического соединения с приводом генератора, а трубчатые поршни статора и ротора закреплены на пружинах растяжения, установленных между корпусом и торцами, соответственно, трубчатых поршней статора и ротора с возможностью колебания последних в противофазе один относительно другого. The proposed, as well as the well-known, linear electric generator contains a housing in which the rotor and stator are coaxially placed, with the possibility of their relative translational movement along one axis and intended for their kinematic connection with the generator drive. The stator is made in the form of a winding that covers the rotor with a group of permanent magnets, and the stator leads are designed to connect loads to them, and, according to the invention, the linear generator is made in the form of a two-piston hydraulic system in which the cavity of the housing with the stator and rotor is filled with mineral high purity and low viscosity oils, such as transformer oils. The stator is made in the form of a tubular piston from a non-magnetic material with a three-phase winding fixed to it and a magnetic contactor made by spiral winding from a soft magnetic wire and a supporting element. The rotor is made in the form of a tubular piston from non-magnetic material with a group of permanent magnets placed on it outside, provided with pole concentrators and two mounted coaxially with the rotor on opposite ends of the tubular rotor piston, rods designed for their kinematic connection with the generator drive, and stator tubular pistons and rotor mounted on tensile springs installed between the housing and the ends, respectively, of the tubular pistons of the stator and rotor with the possibility of oscillation of the latter in opposite phase relative to one another.
Особенностью предлагаемого линейного электрогенератора является и то, что полюсные концентраторы ротора закрыты снаружи тонкостенной трубой из немагнитного материала. A feature of the proposed linear electric generator is that the rotor pole concentrators are closed externally with a thin-walled pipe made of non-magnetic material.
Во время проведения патентно-информационных исследований при подготовке настоящей заявки авторами не обнаружены конструкции линейного электрогенератора с указанной выше совокупностью существенных признаков, что доказывает соответствие заявляемого технического решения критерию изобретения "новизна".
Технический результат, полученный в результате осуществления предлагаемого изобретения состоит в создании условий для использования в качестве конструктивного элемента генератора жидкости, которой заполняют полость корпуса генератора. Благодаря тому, что жидкость является практически несжимаемой, в предлагаемом устройстве обеспечивается одновременное движение в жидкости, но в противоположных направлениях статора и ротора, для осуществления которого не требуется применение дополнительных сложных механизмов, таких, как например, редукторы. Такой технический результат позволяет упростить конструкцию линейного генератора, уменьшить его габариты, снизить его себестоимость и уменьшить затраты на его обслуживание. Кроме того, за счет создания условий для относительного перемещения ротора и статора в противоположных направлениях, относительная скорость их перемещения увеличивается примерно в 2 раза, что позволяет использовать его для преобразования в электрическую энергию энергии воды, в частности волн, или энергии слабых и умеренных ветров. During the conduct of patent information research in the preparation of this application, the authors did not find the design of a linear electric generator with the above set of essential features, which proves the conformity of the claimed technical solution to the criteria of the invention of "novelty". The technical result obtained as a result of the implementation of the present invention is to create conditions for use as a structural element of a fluid generator, which fill the cavity of the generator housing. Due to the fact that the fluid is practically incompressible, the proposed device provides simultaneous movement in the fluid, but in opposite directions of the stator and rotor, which does not require the use of additional complex mechanisms, such as, for example, gearboxes. This technical result allows us to simplify the design of the linear generator, reduce its dimensions, reduce its cost and reduce the cost of its maintenance. In addition, by creating conditions for the relative movement of the rotor and stator in opposite directions, the relative speed of their movement increases by about 2 times, which allows it to be used to convert water energy, in particular waves, or the energy of weak and moderate winds into electrical energy.
В исследуемых технических решениях, которые вошли в уровень техники, авторами не выявлено влияния предписываемых предлагаемому изобретению преобразований, характеризуемых отличительными от прототипа существенными признаками, на достижение указанного технического результата. Это доказывает соответствие предлагаемого технического решения критерию изобретения "изобретательский уровень". In the studied technical solutions, which are included in the prior art, the authors did not reveal the effect of the transformations prescribed by the present invention, characterized by significant features distinctive from the prototype, on the achievement of the specified technical result.

Предлагаемый линейный генератор, содержит совокупность существенных признаков - конструктивных элементов устройства, каждый из которых известен на сегодняшний день. Учитывая изложенное, а также то, что предлагаемый линейный генератор может быть использован во многих отраслях народного хозяйства, в частности, в небольших фермерских хозяйствах, удаленных от линий электропередач хозяйствующих объектах, метеорологических станциях и т.п., можно сделать вывод о том, что предлагаемое решение соответствует критерию изобретения "промышленная применимость". The proposed linear generator contains a set of essential features - structural elements of the device, each of which is known today. Given the above, as well as the fact that the proposed linear generator can be used in many sectors of the economy, in particular, in small farms, far from power lines, economic facilities, meteorological stations, etc., we can conclude that the proposed solution meets the criteria of the invention of "industrial applicability".
Сущность предлагаемого изобретения объясняется схематическими чертежами На фиг. 1 , 2 - показана конструкция линейного электрогенератора. The essence of the invention is explained by schematic drawings. FIG. 1, 2 - shows the design of a linear electric generator.
На фиг. 3, 4 - показана работа линейного генератора в зависимости направления движения ротора относительно статора.
Предлагаемый линейный электрогенератор содержит корпус 1, в котором соосно размещены статор 2 и ротор 3, которые образуют двухпоршневую гидравлическую систему. Полость корпуса 1 со статором 2 и ротором 3 заполнены минеральным маслом высокой чистоты и низкой вязкости - трансформаторным маслом. Статор 2 изготовлен в виде трубчатого поршня из немагнитного материала с закрепленной на нем трехфазной обмоткой 4 и магнитным замыкателем 5, выполненным спиральной намоткой из магнитомягкой проволоки и несущего элемента 6. Статор 2 имеет вид монолитной конструкции, все промежутки между элементами которого заполнены компаундом, который после полимеризации становится достаточно твердым. Ротор 3, изготовлен в виде трубчатого поршня из немагнитного материала с группой размещенных на нем снаружи постоянных магнитов 7, снабженных полюсными концентраторами 8. На роторе 3 установлены соосно с ним на противоположных торцах трубчатого поршня штоки 9. Штоки 9 предназначены для их кинематического соединения с приводом генератора /не показано/. Трубчатые поршни статора 2 и ротора 3 закреплены на уравновешивающих пружинах (пружинах растягивания), соответственно 10 и 1 1, установленных между корпусом 1 и торцами, соответственно, трубчатых поршней статора 2 и ротора 3 с возможностью колебания последних в противофазе один относительно другого. Значения площадей сечений статора 2 и ротора 3 близки. Корпус 1 обеспечен также уплотнителями 12 для исключения вероятности протечек трансформаторного масла, например при повышении температуры в корпусе 1. Выводы статора 2 для полученного трехфазного тока выведены по спирали на клеммную колодку на внешней поверхности корпуса 1 /не показано/. In FIG. 3, 4 - shows the operation of a linear generator depending on the direction of movement of the rotor relative to the stator. The proposed linear electric generator comprises a housing 1, in which a stator 2 and a rotor 3 are coaxially placed, which form a two-piston hydraulic system. The cavity of the housing 1 with stator 2 and rotor 3 is filled with mineral oil of high purity and low viscosity - transformer oil. The stator 2 is made in the form of a tubular piston made of non-magnetic material with a three-phase winding 4 fixed to it and a magnetic closure 5 made by spiral winding from the soft magnetic wire and the supporting element 6. The stator 2 has the form of a monolithic structure, all the gaps between the elements of which are filled with a compound polymerization becomes hard enough. The rotor 3 is made in the form of a tubular piston of non-magnetic material with a group of permanent magnets 7 mounted on it outside and equipped with pole concentrators 8. The rods 9 are mounted on the rotor 3 coaxially with it at the opposite ends of the tubular piston. The rods 9 are designed for their kinematic connection with the drive generator / not shown /. The tubular pistons of the stator 2 and rotor 3 are mounted on balancing springs (tension springs), respectively 10 and 1 1, installed between the housing 1 and the ends, respectively, of the tubular pistons of the stator 2 and rotor 3 with the possibility of oscillation of the latter in antiphase one relative to the other. The cross-sectional values of the stator 2 and rotor 3 are close. The housing 1 is also provided with seals 12 to eliminate the likelihood of transformer oil leaks, for example, when the temperature in the housing 1 rises. The stator leads 2 for the obtained three-phase current are spiral-fed to the terminal block on the outer surface of the housing 1 / not shown /.
Полюсные концентраторы 8 ротора 3 закрыты снаружи тонкостенной трубой 13 из немагнитного материала, предназначенной для получения гладкой (ровной) поверхности. Зазор между смежными цилиндрическими поверхностями статора 2 и ротора 3 должен быть наименьшим, что направлено на уменьшение магнитного сопротивления магнитной системы и, как следствие, на снижения потерь мощности. The pole concentrators 8 of the rotor 3 are closed on the outside with a thin-walled tube 13 of non-magnetic material, designed to obtain a smooth (even) surface. The gap between adjacent cylindrical surfaces of the stator 2 and rotor 3 should be the smallest, which is aimed at reducing the magnetic resistance of the magnetic system and, as a result, at reducing power losses.
Предлагаемый линейный электрогенератор работает так. The proposed linear electric generator works like this.
Благодаря использованию жидкости в замкнутом пространстве полости корпуса 1 из-за того, что указанная жидкость не сжимается под действием нагрузок, которые могут воздействовать на нее во время движений относительного друг друга статора 2 и ротора 3, движение ротора 3, например на 1 сантиметр вниз, вызывает движение статора 2 на 1 сантиметр вверх и наоборот. То есть, перемещение ротора 3 со
скоростью 1 метр в секунду вызывает такое же движение статора 2 в противоположном направлении. При этом скорость перемещения статора 2 относительно ротора 3 составляет 2 метра в секунду. Due to the use of fluid in the enclosed space of the cavity of the housing 1 due to the fact that the fluid is not compressed under the action of loads that can affect it during the movements of the relative stator 2 and rotor 3, the movement of the rotor 3, for example, 1 centimeter down, causes the stator to move 2 by 1 centimeter up and vice versa. That is, the movement of the rotor 3 with at a speed of 1 meter per second causes the same movement of the stator 2 in the opposite direction. The speed of movement of the stator 2 relative to the rotor 3 is 2 meters per second.
Таким образом, предлагаемый линейный электрогенератор позволяет существенно уменьшить сложность, габариты и себестоимость по сравнению с генератором-прототипом за счет применения в нем в качестве конструктивного элемента жидкости, что позволило не применять в конструкции генератора дополнительных сложных механизмов.
Thus, the proposed linear electric generator can significantly reduce the complexity, dimensions and cost in comparison with the prototype generator due to the use of liquid as a structural element, which allowed not to use additional complex mechanisms in the generator design.
