Description
УСТРОЙСТВО ОХЛАЖДЕНИЯ И АЭРАЦИИ НАТУРАЛЬНОГО ГАЗОНА NATURAL LAWN COOLING AND AERATION DEVICE
Полезная модель относится к средствам охлаждения прикорневого слоя натурального газона, преимущественно спортивного; например, футбольного поля или теннисного корта, в условиях жаркого лета или жаркого климата. The utility model relates to means for cooling the root layer of a natural lawn, mainly sports; for example, a soccer field or tennis court, in hot summers or hot climates.
Известна система подпочвенной аэрации футбольного поля с помощью главной и латеральных труб, распространяющих воздух в корневую зону травяного газона, также способствующая его более быстрому прогреву или охлаждению [htps://www.s-bc.ru/news/raskryta-tajna-gazona-na-otkrytie- arena.html]. Однако такая система не обеспечивает равномерного воздействия по площади поля. A well-known system of subsoil aeration of a football field with the help of the main and lateral pipes spreading air to the root zone of a grass lawn, also contributing to its faster heating or cooling [htps: //www.s-bc.ru/news/raskryta-tajna-gazona- na-otkrytie- arena.html]. However, such a system does not provide uniform exposure over the field area.
Наиболее близок по технической сущности к заявляемому патент RU N°2263736, Е01С 13/02, оп. 10.11.2005, касающийся обогрева воздуха, подаваемого по трубе под футбольным полем, тепловой пушкой. Согласно описанию RU N°2263736 (прототип), при подаче теплого воздуха компрессором через тепловую пушку воздух, проникая через слой грунта, образует на поверхности газона воздушную тепловую подушку, которая препятствует промерзанию верхнего слоя газона в зимний период; а в остальные времена года служит для просушки грунта и обеспечения корней растений воздухом (аэрации). Closest to the technical nature of the claimed patent RU N ° 2263736, ЕСС 13/02, op. November 10, 2005, concerning the heating of air supplied through a pipe under a football field with a heat gun. According to the description of RU N ° 2263736 (prototype), when warm air is supplied by the compressor through the heat gun, air penetrating through the soil layer forms an air heat cushion on the surface of the lawn that prevents the freezing of the top layer of the lawn in winter; and in other seasons it serves to dry the soil and provide the roots of plants with air (aeration).
Недостатком прототипа является отсутствие функции охлаждения прикорневого слоя спортивного газона, необходимой в условиях жаркого лета или жаркого климата. The disadvantage of the prototype is the lack of cooling function of the root layer of a sports lawn, necessary in hot summers or hot climates.
Решаемая задача и ожидаемый технический результат заключаются в разработке эффективного устройства охлаждения и аэрации прикорневого слоя натурального газона, в том числе спортивного, за счет подачи охлажденного
воздуха по каналам, проложенным под всей площадью газона в виде змеевика; без необходимости применения и, соответственно, трудоемкой укладки дорогостоящих труб. The problem to be solved and the expected technical result are to develop an effective device for cooling and aeration of the root layer of a natural lawn, including a sports one, by supplying chilled air through the channels laid under the entire area of the lawn in the form of a coil; without the need for application and, accordingly, laborious laying of expensive pipes.
Поставленная задача решается тем, что предлагается устройство охлаждения и аэрации прикорневого слоя натурального газона с помощью охлажденного воздуха, подаваемого под газон, уложенный на решетку в герметичной коробке, включающее параллельные опоры для решетки, выложенные по дну герметичной коробки с образованием каналов в виде змеевика под площадью газона для циркуляции охлажденного воздуха. Схема предлагаемого устройства представлена на фиг. 1-4, где: The problem is solved by the fact that a device is proposed for cooling and aeration of the root layer of a natural lawn with the help of cooled air supplied under a lawn laid on a grate in a sealed box, including parallel supports for the grate laid on the bottom of the sealed box with the formation of channels in the form of a coil under an area lawn for the circulation of chilled air. A diagram of the proposed device is shown in FIG. 1-4, where:
1 - газонная площадка 1 - lawn area
2 - герметичная коробка 2 - sealed box
3 - внутренний бортик 3 - inner side
4 - каналы 5 - агрегат охлаждения воздуха 4 - channels 5 - air cooling unit
6 - потоки охлажденного воздуха 6 - flows of chilled air
7 - параллельные опоры 7 - parallel supports
8 - решетка 8 - grill
9 - компрессор 10 - выводящая труба. 9 - compressor 10 - exhaust pipe.
Предлагаемое устройство охлаждения и аэрации прикорневого слоя натурального газона с помощью охлажденного воздуха, подаваемого под газон, уложенный на решетку в герметичной коробке, работает следующим образом. The proposed device for cooling and aeration of the root layer of a natural lawn with the help of chilled air supplied under a lawn laid on a grate in an airtight box, works as follows.
Газонная площадка 1 представляет собой герметичную (например, бетонную) коробку 2 с внутренним бортиком 3 (например, также из бетона). По дну коробки параллельно друг другу расположены опоры 7 (например, также из бетона) для решетки 8, на которой уложен газон (плодородный грунт с проросшими травянистыми растениями). Под решеткой 8 (и, соответственно,
под площадью газона) между опорами 7 образованы каналы 4 в виде змеевика, для чего расположенные рядом параллельные друг другу и равные между собой по длине опоры 7 упираются в противоположные стороны внутреннего бортика 3 герметичной коробки 2 (фиг. 1, фиг. 4). Такое расположение опор 7 обеспечивает смену направления потока охлажденного воздуха 6, подаваемого в каналы 4 от агрегата охлаждения воздуха 5, всякий раз, когда поток 6 достигает противоположной стороны коробки. Поток охлажденного воздуха 6, кроме охлаждения, одновременно способствует и аэрации плодородного прикорневого слоя газона, уложенного на решетку 8. Таким образом, в предлагаемом устройстве каналы 4 располагаются под всей площадью газона в виде змеевика для обеспечения циркуляции потоков охлажденного воздуха 6, соответственно, под всей площадью газона. The lawn pad 1 is a sealed (for example, concrete) box 2 with an inner rim 3 (for example, also made of concrete). On the bottom of the box, supports 7 are arranged parallel to each other (for example, also made of concrete) for a grate 8 on which a lawn is laid (fertile soil with sprouted grassy plants). Under the grill 8 (and, accordingly, under the lawn area) between the supports 7 channels 4 are formed in the form of a coil, for which the adjacent parallel to each other and equal to each other along the length of the supports 7 abut against opposite sides of the inner side 3 of the airtight box 2 (Fig. 1, Fig. 4). This arrangement of the supports 7 provides a change in the direction of the flow of chilled air 6 supplied to the channels 4 from the air cooling unit 5, whenever the flow 6 reaches the opposite side of the box. The flow of chilled air 6, in addition to cooling, also contributes to aeration of the fertile root layer of the lawn laid on the grill 8. Thus, in the proposed device, the channels 4 are located under the entire area of the lawn in the form of a coil to circulate the flows of chilled air 6, respectively, under the entire the area of the lawn.
Охлажденный воздух подается в змеевик, образованный каналами 4, от агрегата охлаждения воздуха 5 (фиг. 2, фиг. 4) с помощью вентилятора, являющегося элементом агрегата 5; а компрессор 9 (фиг. 1) обеспечивает аэрацию охлажденным воздухом 100% площади газона. Потоки нагнетаемого воздуха выводятся из устройства с помощью выводящей трубы 10 (фиг. 4). Cooled air is supplied to the coil formed by channels 4 from the air cooling unit 5 (Fig. 2, Fig. 4) using a fan, which is an element of the unit 5; and the compressor 9 (Fig. 1) provides aeration with chilled air 100% of the area of the lawn. The flows of injected air are removed from the device using the output pipe 10 (Fig. 4).
Элементы решетки 8 могут иметь разную площадь в зависимости от их расположения; а именно: элемент решетки, располагаемый над участком смены направления потока охлажденного воздуха, может иметь площадь большего размера (показан в верхней части фигуры 3) относительно элементов решетки, расположенных над другими участками змеевика (остальные элементы решетки 8 на фигуре 3). Elements of the lattice 8 may have a different area depending on their location; namely, the lattice element located above the section for changing the direction of the flow of chilled air may have a larger area (shown in the upper part of figure 3) relative to the lattice elements located above other sections of the coil (other lattice elements 8 in figure 3).
В предлагаемом устройстве нет необходимости применения и, соответственно, трудоемкого монтажа большого количества труб для подачи охлажденного воздуха. In the proposed device there is no need for the application and, accordingly, the laborious installation of a large number of pipes for supplying chilled air.
Предлагаемое устройство позволяет сохранить натуральный газон и/или травяное покрытие спортивной площадки в оптимальном состоянии в период жаркого лета или в условиях жаркого климата благодаря равномерному охлаждению и аэрации плодородного прикорневого слоя полной площади газона.
The proposed device allows you to keep the natural lawn and / or grass cover of the sports ground in optimal condition during hot summers or in hot climates due to uniform cooling and aeration of the fertile root layer of the full area of the lawn.
