Description

The invention relates to the field of lighting engineering and can be used in industrial, repair and rescue operations both on flat spaces and, for example, in a foundation pit or in a railway carriage, providing shadowless illumination of the entire working space. In addition, the invention is intended to illuminate the playing and training football fields of indoor stadiums at night or overcast, which contributes to the growth of grass on the field, while maintaining the density, uniformity and high quality of its natural green coating. For such sites, the installation completely compensates for the lack of solar energy and allows you to keep grass in all areas of the football field of the stadium at a high level, with quality not worse, and often even higher than that that grows outdoors.

According to experts, more than 50% of football fields in Europe are equipped with cable heating systems for the football field lawn. In the north of Europe, cable systems are used more for heating fields, and in the south - liquid heating systems. Large stadiums almost always have the required electrical power. Powerful lighting systems are usually installed there, which are used only during matches. It is easy to make the necessary changes so that electricity can be used for the cable system during periods when the lighting system is not used. Such systems provide earlier grass growth, quick drying of the field after rain, reducing injuries to players on the field, uniform heating throughout the field. The reliability of each system is determined by the quality of design, manufacture and installation. Both systems have a high degree of reliability, but in the event of an accident the cable system is protected by automatic shutdown, and liquid heating can leak antifreeze (see the article "Ground heating system", posted on the website Comfort and Ecology on the Internet at: http: / /com-eco.ru/content/view/77/83/, discovered in May 2011).

In addition to all the advantages related to the possibility of obtaining a dry playing field at any time, there is one feature. Which seriously affects the gameplay in the stadium, for example, when playing soccer. This is the state of the grass itself, providing a given degree of slip. Despite the fact that the task of maintaining grass cover itself is well known and studied technically, for indoor stadiums or stadiums with a movable roof or a partial roof, maintaining the grass surface of a football field is a purely technical problem.

To ensure the normal growth of grass on the football field, sunlight is required - at least four hours daily. Traditionally, sliding or retractable coverings are used for this, however, a large snow load did not allow the use of such a solution. The only option was to move the football field itself. A natural football pitch measuring 120 x 85 meters weighs 8,300 tons. This is the first hanging arena in the world. She can, "hovering" on an air cushion, move at a speed of 4 meters per minute with 34 wheels. The football arena is set outside the stadium in an open area. The arena can unfold, focusing on sunlight, which improves the conditions for grass growth on the lawn, see the article "High-tech buildings - the possibilities of modern construction", author Yuri Tabunshchikov, doctor tech. Sci., Corresponding Member of RAASN, President of NP "ABOK", posted on the website of ESOTESO in the Internet at the address: http://www.ecoteco.ru/id568/, was discovered in May 2011).

But not all stadiums are equipped with a movable football field, a significant part of the stadiums are equipped with a stationary field with a permanent or removable grass cover. For such stadiums, lighting installations are used that are placed on the field and around the field, with which they illuminate and heat the surface of the field to maintain a live state of the grass at given soil parameters. Typically, these are rack-type illuminators.

Known lighting installations that provide illumination of the working space by moving lighting devices in the horizontal and / or vertical planes (SU No. 1831637, 1767285, DE No. 1041887 and GB No. 201841, F21V 21/00, F21V 21/22). These lighting installations contain pendant lighting, for example cylinders filled with gas lighter than air, on which lighting devices (lamps) are mounted. The cylinders are held at the required height by means of extensions and connecting cords, or the lighting systems contain racks of various shapes with a rod or rods with lighting devices attached to them that can be moved.

A portable lighting installation is also known, containing a base formed by legs fixed with screeds at equal angles between each other, a telescopically mounted support tube and a movable stand with two flanges (crossbars) for fixing one lighting device (searchlight) connected by a cable to a power source. The movable stand is fixed at the desired height of the support pipe and at the base by means of a locking screw. The power cable of the lighting device is missing inside the movable stand / Book of the author M.S.Dadiomov. "Spotlight", L .: Energy, 1978, S. 60, Fig. 3-16 /.

A known installation is portable lighting with tunable fittings, containing a base formed by legs in the form of pipes fixed at equal angles to each other, a pipe stand, a crossbar mounted on a rack, and at least one lighting device mounted on a bar and connected by a cable to a power source, the base is equipped with a connecting unit made in the form of four pipe sections rigidly interconnected: a central pipe section for telescoping the rack therein, having the possibility of sequentially connecting the next leg and three lateral pipe sections for fixing legs in each of them, also having the possibility of sequentially connecting the next leg; the crossbar is equipped with a hub in the center for fixing it to the rack; along the edges - with two hooks for winding an electric power cable for searchlights and several rings evenly spaced on the crossbar for detachable fastening of stretch marks; and also equipped with a protective frame and together with the lighting device forms a lighting head; each leg is equipped with removable hooks for winding or securing the lower end of the extension; the end of each leg is equipped with a removable support element; detachable connections of the pipe elements, namely, the connection of the legs with the lateral pipe segments of the connecting unit, as well as the connection of the legs and racks to each other, are made at one end in the form of a stepped cylindrical pin with two radial holes with the possibility of interaction with the end of another connected pipe element, also having two radial holes; all radial holes are coaxial and interconnected by a needle pin (RU No. 2304249, F21L 14/00, publ., 10.11.2006, adopted as a prototype).

A common drawback of the considered lighting installations is their low performance, due to the fact that for such a large area as a football field, a large number of such installations are required, the placement of which requires a lot of time and experience for the adjusters to ensure uniform illumination of the field surface. In addition, each such installation is structurally complex and requires constant technological care and monitoring of the working condition of the nodes.

The present invention is aimed at achieving a technical result, which consists in increasing the operational performance of the lighting system and ease of use by reducing the time for installation / dismantling and ensuring uniform illumination of a large surface of the playing field.

The specified technical result is achieved by the fact that in the installation of lighting mobile for lighting playgrounds containing a support system, on which are fixed lighting fixtures mounted on a support system and connected by cable through a control panel to a power source, the support system includes a support beam, at the ends fixed on support racks, each of which is mounted on a two-wheeled chassis, which has the ability to rotate relative to the rack and fixation in the selected angular position and, a carriage placed on the beam with the possibility of moving along the beam and to which two shaped cross-members are mounted pivotally at one end, laid along the beam when the carriage is located at one of the support posts, and four shaped cross-members, two pivotally attached to each end of the beam and having the possibility of arrangement along the beam and when turning in the direction perpendicular to the beam, as well as elements for fixing the cross members relative to the beam when they are located along the beam and the position at which all associated crossmember positioned perpendicular to the beam, and lighting mounted remotely on said beams and are connected electrically to the control panel mounted on one end of the beam.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The invention is illustrated by a specific example of execution, which, however, is not the only possible, but clearly demonstrates the possibility of achieving the desired technical result.

According to the present invention, a construction of a mobile lighting installation is considered, that is, having the ability to move on a supporting surface on wheels. The device is designed to illuminate the playing and training football fields of indoor stadiums at night or in cloudy times, which contributes to the growth of grass on the field, while maintaining the density, uniformity and high quality of its natural green coating. For such sites, the installation completely compensates for the lack of solar energy and allows you to keep grass in all areas of the football field of the stadium at a high level, with quality not worse, and often even higher than that that grows outdoors.

The lighting installation contains a support system (Figs. 1-3), which includes a main support beam 1, fixed at the ends to support posts 2, each of which is mounted on a two-wheeled support chassis 3, which can be rotated relative to the rack and fixed in the selected angular position. The stand can be made tubular or shaped, as shown in figure 2. The rack is attached to the beam 1 and mounted on a support chassis 3, which is based on two wheels 4. The support chassis has the ability to rotate in a horizontal plane relative to the rack and fixation in the turned position by bolts, a pin or other known mechanism. The rotation of the chassis with the wheels relative to the rack is carried out by a drawbar 5 or a draft, which is a coupling device that allows the tractor to move the installation. Each drawbar is equipped with such drawbar or traction. To prevent spontaneous rotation of the wheels during installation of the installation and its deployment under the wheels are set shoes.

A carriage 6 is mounted on the carrier beam, mounted on the beam with the possibility of movement along it and fixing in a predetermined position. Two shaped structures of the cross member 8 are attached to the carriage pivotally (by means of horizontal hinges 7) at one end, laid along the beam 1 when the carriage is located at one of the support posts. In this position, the carriage 6 is fixed against movement, and the cross members 8 are fixed on the carriage from rotation around the hinges 7. The cross members 8 are attached to the carriage 6 on the sides of the carrier beam 1.

To each end of the carrier beam 1 are attached on its sides two shaped structures of the cross member 9 from one end and 10 from the other end. These crossbars 9 and 10 are pivotally (by means of horizontal hinges 11 and 12 respectively) at one end attached to the beam 1 so that they can take a position along the beam during rotation. Moreover, the distance between the hinges 11 is made greater than the distance between the hinges 12, which allows the cross-member 9 to be laid outside the cross-members 10, which, in turn, are laid along the cross-members 8. All the cross-sections 9 and 10 have clamps for their attachment either to the beam or to the adjacent crossbar to exclude spontaneous reversal. When the latches are removed, the crossbars 9 and 10 can be deployed in the direction perpendicular to the beam 1. In this expanded position, the crossbars are fixed with fixing elements (for example, braces 13 or struts or ties) relative to the beam at a position in which all of these crossbars are located perpendicular to the beam.

All crossbars and beams are made of profile (metal, polymer or a combination of these materials).

Lighting devices 14 are mounted remotely on the indicated crossbars and are connected electrically with the control panel 15 or when dividing into groups of lighting lamps with several control panels. These control panels are mounted on one end of the beam or on each end of the beam in the control cabinet 16. Lighting devices connected by cable through the control panel to the power source. As lighting devices, fixtures with phytolamps were used (the article “Lamps - selection criteria” posted on the Greenlnfo.ru website on the Internet at http://www.greeninfo.ru/for_landscaping/phytolamps.html). The use of phytolamps for illumination of plants in confined spaces or in the winter season is more effective in physiological terms. For photosynthesis, phytoluminescent lamps are preferable and more economical (20 watts of consumption - 100 watts of return), but their lilac-pink glow is unnatural and harmful to human eyes, can provoke headaches. Therefore, it is undesirable to use them in residential premises without an external mirror reflector. Osram Fluora phytolamps can be found on sale. To illuminate the window sill with a length of about 1 m, one - two 18-watt lamps will be enough. You can use a domestic lamp LFU-30 (30 W), it is enough to illuminate an area of 0.4 × 0.7 m. The light of specular phytolamps from Enrich (Hungary) with a power of 60 W is less irritating to the eyes. They are screwed into a regular cartridge. However, when turned on every day, these lamps do not last long - no more than six months. The above disadvantages are deprived of Paulmann phytolamps with a capacity of 40, 60 and 100 watts. They are also screwed into a regular cartridge. Their difference from other lamps consists in a special layer deposited on the glass of the lamp, and also in that they practically do not heat up, and therefore do not cause overheating of leaves and grass. Their service life exceeds the service life of a conventional incandescent lamp by 3-4 times.

A control installation model made for a football field has the following technical characteristics of the installation: power - 62 kW, weight - 2.5 tons, height - 2300 mm, length - 11540 mm, unfolded width - 22000 mm, folded width - 2200 mm. This installation is maintained by two workers to ensure uniformity and synchronism in the deployment of the cross-beams and their laying along the beam 1.

The installation is operated as follows.

The position of all the installation elements in the assembled position is shown in Figs. 1 and 2. In this state, the installation (with the chassis unlocked and the shoes removed), the tractor (by coupling with the drawbar) moves to the playing field and is aligned at the location on this field, taking into account the turn of the crossbars .

After that, the workers fix the chassis relative to the racks, place shoes under the wheels and remove the clips from the cross members 9, freeing them from communication with either the beam 1 or the adjacent cross member and unroll them evenly in the direction perpendicular to the beam 1. At the same time, uniformity and smoothness are necessary to ensure the equilibrium of the installation and prevent its overturning. After a turn of the cross-beams 9, the braces 13 are fixed on the beam 1 and on these cross-beams so that the cross-beams can no longer rotate (Fig. 4).

Similar operations are carried out on the crossbars 10 (figure 4). Only after unfolding, the fixation of these cross members is carried out after moving the carriage 6.

After that, the clamps are removed from the cross members 8, breaking their connection with the carriage 6 or with the beam 1, and the cross members 8 are turned in the direction perpendicular to the beam 1. Then the carriage is moved along the beam to the position where the cross members 8 are located approximately in the middle between the cross members 9 and 10 The carriage is fixed relative to the beam 1 and the cross members 8 relative to the carriage 6 or beam 1 (Fig. 5).

Then, electrical cables are connected to the terminal boxes output to the ends of the cross members 9 and 10, and the control mode 15 is selected for turning on the lamps with setting the time of their operation or the sequence of operation of the groups of lamps.

Installation is carried out in the reverse order.

The present invention has improved performance, as it is simply and quickly assembled, disassembled, compactly transported and stored. Lighting installation consists of simple, technological, universal structural elements (modules) and other cheap structural elements. The unit is easily transformed horizontally to achieve shadowless lighting in any desired workspace.
