Description

The technical field to which the utility model relates.

This utility model relates to high-mast lighting systems designed to illuminate large open spaces, industrial areas, ski slopes and sports fields, providing protection against lightning strikes of buildings and structures, as well as surge protection in the mains.

State of the art

A high-mast lighting system is disclosed in the prior art, disclosed in RU 103598 U1 (published on 04/20/2011), comprising a lightning rod, a cap, a frame, an arm, lamps, an anchor (intermediate) suspension, a support barrel, a winch, an installation control switchboard, a protective cover, base mounting flange. The structure of the anchor suspension of the known installation includes cheeks, in the lower part of which with the help of clamps, thimble and bolt connection a single steel cable is fastened, wound / wound on the winch drum. A lanyard is also attached to the lower parts of the cheeks, which is designed to fine-tune the fixation of the frame with the lamps in the upper working position by fixing the fork located in the lower part of the lanyard on the protrusion located on the inner wall of the lower section of the lighting support. Three steel ropes are attached to the upper parts of the cheeks with bolts and thimbles, designed to suspend the frame with lamps, fixed with clamps and passing through the bushings installed in the composite stud. The composite hairpin mounted on the upper parts of the cheeks is designed for the correct location of the three steel ropes of the frame suspension with lamps and an electric cable that provides power to the lamps. This technical solution is the closest in technical essence of the claimed utility model and is selected as its closest analogue - prototype.

The technical solution known from RU 103598 U1 allows the installation of standard fixtures, their maintenance and replacement without the use of external lifting devices or devices, and also simplifies the design of the unit, which makes the transition from a system of three steel ropes, providing a suspension of the frame with fixtures, to one steel cable , winded / wound on the drum of the winch in the process of raising / lowering the frame with lamps, and, as a result, improve the operational characteristics of the lighting system ovki. In addition, the technical solution known from RU 103598 U1 eliminates the possibility of moisture getting inside the support due to the execution of the cap of the head protecting all elements and assemblies located in it from the adverse effects of the external environment.

However, the disadvantages of the known lighting installation - prototype include the following. This lighting installation is designed to illuminate roads, a guarded territory and parking lots, which, in particular, determines low requirements for the installation height and the characteristics of the lighting it provides, in particular, for the characteristics of the lamps used in it. The area illuminated by the installation - the prototype of the space is limited, primarily due to the design of the installation frame, which surrounds the support shaft, being in close proximity to it. This embodiment of the frame, obviously, simplifies the design of the lighting installation and ensures that the frame is located essentially under the protective cover of the head, which increases the protection of the suspension ropes of the frame and the frame itself from the adverse effects of the external environment. However, this design of the frame makes it impossible to spread the luminaires installed on it to a significant distance from the axis of the support, limiting the area of the space illuminated by the installation, even with an increase in the height of the support of this lighting installation. In addition, the use of an installation - an analogue of standard fixtures, despite their uniform distribution on the frame, does not allow for a high-quality overall light distribution diagram of the installation. Thus, the use of these lighting installations for lighting large open spaces, industrial areas, ski slopes and sports grounds is impractical due to the small area illuminated by such installations and the insufficient quality of the light distribution provided by them. It is obvious that the problem of ensuring uniform illumination of open spaces of a large area cannot be solved by simply increasing the installation height - the prototype, but requires a comprehensive solution to a number of engineering problems, consisting in a new constructive implementation of both the installation as a whole and its individual elements.

Utility Model Disclosure

The objective of this utility model was to overcome the shortcomings of the prior art by creating a high-mast lighting installation, the design of which allows the installation of various heights, including high installations, providing a high-quality overall light distribution diagram and capable of replacing up to several dozen installations - analogues.

To solve the problem and overcome the shortcomings of the prior art in the development of this utility model, the following engineering problems were solved, in particular:

- the creation of a frame for the installation of lighting devices, the design of which allows to provide an increased distance between the lighting devices and the longitudinal axis of the support, sufficient to provide high-quality, essentially uniform in all directions of lighting large open areas, in particular, with an increase in the height of the lighting installation; and

- the creation of lighting devices for installation on the said frame of an improved design to ensure high-quality, essentially uniform in all directions of lighting, including, according to the requirements of existing GOST lighting of large open areas, as well as ensuring the protection of these lighting devices from adverse environmental influences .

The technical result achieved by the implementation of the utility model is to significantly increase the area illuminated by the installation of the space and improve its light distribution compared with the known installations of the prior art, including increasing the height of the lighting installation. Additionally, the high-mast lighting system according to the utility model provides protection against lightning strikes of buildings and structures, as well as surge protection in the mains.

The specified technical result is achieved due to the design features of a specially designed carriage lifting mechanism, which additionally includes an outer ring extending at a considerable distance from the central axis of the support, onto which new lighting fixtures are installed, each of which includes five lamp modules with light distribution diagrams 45 °, which are located with a mutual turn of the extreme four modules at an angle of 23 ° relative to the central module. The indicated arrangement of the modules of the luminaires in the lighting device allows you to provide a total light distribution diagram of at least 41 ° × 92 °.

Protection against lightning strikes of buildings and structures, as well as overvoltage protection in the supply network, is achieved by installing a high-mast lighting installation on the support, in its upper section, a lightning rod.

More specifically, the task is solved due to the fact that the high-mast lighting installation according to the utility model contains:

a metal support of variable cross-sectional height, in particular of a multifaceted shape, including a lower section and an upper section, moreover, a support flange and an inspection hatch are made in the lower section of the support;

Utility Model Implementation

The lighting system according to a preferred embodiment of the utility model shown in FIG. 1, contains a lightning rod (1), a head (2), a carriage (3), a traverse (4), a support (5), a winch (6), an electric cabinet (7) for controlling the installation, an inspection hatch (8), a flange (9 ) support.

In this embodiment, a metal support (5) of a multifaceted cross-section of varying height is made of sheet steel by bending, with one or two longitudinal welds, and the support (5) is protected from corrosion by hot dip galvanizing, for example, according to GOST 9.307.-89 . At the same time, the support can be manufactured in other suitable ways, including having a circular cross section, and the utility model is not limited to this manufacturing option.

On the support (5) of the lighting installation, in its upper section, a lightning rod is installed to protect against lightning strikes of buildings and structures, as well as to protect against overvoltage in the supply network.

Shown in FIG. 2, the outer ring (10) is made with the possibility of fastening through the brackets (11) to the angular flanges of the carriage (3), to which the traction cables of the head (2) are attached. In this case, the outer ring (10) has a larger diameter than the diameter of the circle described around the outer surface of the carriage (3), which allows the lighting devices (12) mounted on the outer ring to be carried a considerable distance from the central axis of the support. The specified distance can be changed by changing the diameter of the outer ring (10) and selected in accordance with the requirements of a particular embodiment of the lighting installation, in particular, according to the purpose (scope) and the required height of the installation.

Lighting devices (12) are mounted on the outer ring (10), an embodiment of one of which is shown in FIG. 3. In each of the aforementioned lighting fixtures (12), an arrangement of five lamp modules with 45 ° light distribution diagrams is implemented to obtain a total light distribution diagram of at least 41 ° × 92 °. This solution is provided by the mutual rotation of the extreme four modules at an angle of 23 ° relative to the central module in the lighting device.

The indicated spread of the four extreme modules of the lighting device relative to the central module is made in such a way as to provide "limited" light distribution in the glare zone of the device according to GOST 54350-2011 in the area of restrictions at angles of 80 ° (> 100 cd / klm) and 90 ° (> 25 cd / klm). For comparison, when implementing a lighting device that includes five modules of ZhO-08-1000-001 luminaires known and available on the market, located without the indicated arrangement of modules according to this utility model, lighting devices provide only "completely limited" light distribution in the zone glare according to GOST 54350-2011 at angles of 80 ° (> 100 cd / klm) and 90 ° (> 0 cd / klm).

In a preferred embodiment of the utility model, each of the lighting modules is made on the basis of high-performance white-emitting diodes of radiation, as shown in FIG. 3.

At the same time, each module of the lighting device according to the utility model contains a casing (13) shown in FIG. 4, designed to protect the lighting device (12) from possible deformations, both during installation of the lighting device (12), and during operation. The flange (14) along the contour of the casing (13) is designed to give additional rigidity to the casing (13). The second functional purpose of the casing (13) is to protect the lighting device (12) from the accumulation of dust and dirt between the ribs. A fragment of the image of the lighting device (12) with a casing is shown in FIG. 5.

Additionally, another important purpose of the casing (13) is to provide a grid of convection cells. This condition is achieved by evenly spaced holes (15) on the upper surface of the casing, through which the outlet of heated air, as shown in FIG. 6.

The carriage lifting mechanism according to the utility model consists of a carriage (3), a traverse (4), a head (2) with ropes and cables stocked with measured length, with rollers mounted on it and an anchor safety chain.

The installation of the carriage lifting mechanism (3) in accordance with a preferred embodiment of the utility model is implemented, for example, as follows.

The support (5) is mounted on the goats. The winch (6) is installed on the standard holes of the brackets welded into the support in the lower part of the inspection hatch (8). Next, the traction cable is released, fixed through the chain links to the traverse (4) and through the conductor (steel wire) pass it through the support (5) to the winch (6). The end of the cable is fixed on the drum of the winch (6), passing it into the hole in the cheek of the drum and zaposov on the reverse side, and then, slowly rotating the handle, wrap the cable on the drum of the winch (6). Thus, the traverse (4) is introduced into the upper part of the support (5) by winding the cable onto the winch drum (6). Further, upon reaching the traverse (4) of the inspection hatch (8), they continue to wind the cable with the simultaneous tray of the head body (2) until the support flanges (5) and the head (2) are mated.

The fastening of the outer ring (10) is carried out through the brackets to the corner flanges of the carriage (3) with the simultaneous alignment of the structure. The outer ring (10) according to a preferred embodiment of the utility model comprises means for fastening two rope halyards or counterweights, by means of which two rope halyards (or counterweights) are attached to it from opposite sides of the ring to create additional load when lowering the carriage (3) after installing the support (5). After that, during the installation process, fixing wedges are removed from the cams of the head (2). After that, the carriage (3) is lowered 1.5-2 meters from the top of the support (5) using the winch handle (6), while maintaining the tension in the ropes.

The installation of lighting fixtures (12) on the outer ring (10) in accordance with a preferred embodiment of the utility model is carried out, for example, as follows.

After the final installation of the support (5), the carriage (3) with the outer ring fixed on it (10) is lowered onto the support brackets of the support (5). Lighting devices (12) are mounted on the outer ring (10), fixing the brackets to the plane of the ring (10) with bolted joints. In this case, the installation of lighting devices is carried out evenly around the perimeter of the ring (10) for subsequent balancing of the carriage (3). After installing the lighting fixtures, they are connected to the power supply with an electric cable of the appropriate section.

The equipped carriage (3) is lifted from the support brackets and set in a strictly horizontal position. To align the carriage (3) with the outer ring (10), use the nuts and locknuts of the threaded rods of the cables located on the faces of the carriage (3).

The operation of a high-mast lighting system for its maintenance and replacement of lighting devices (12) in accordance with a preferred embodiment of the utility model is carried out, for example, as follows.

Install and fix the mounting brackets for the descent tool, which can be a rotation handle or a power tool, while the guide for mounting the tool vertically and horizontally must be strictly aligned with the axis of the winch drive (6). Next, the rotation handle is mounted on the brackets and introduced into the joint with the shank of the winch (6).

After all of the above actions, the carriage lifting mechanism is ready to work on unlocking and lowering the carriage (3).

Further, the carriage (3) is lifted by rotating the winch rotation handle (6) clockwise. At the moment of exit from the elevator part, the carriage (3) with the outer ring (10) oscillates horizontally and returns to a rest state. After calming the vibrations of the carriage (3) by rotating the winch rotation handle (6) counterclockwise, the carriage (3) is lowered until it slides off the fist guide, as evidenced by the next oscillatory movement of the carriage (3) in the horizontal plane. After the carriage (3) falls 20-30 cm beyond the elevator part, the rotation handle is replaced with a power tool, for which the rotation handle with adapter is removed from the drive axis of the winch (6) and an adapter with a power tool is installed on it. Fasten the power tool to the bracket. After checking the quality of fastening the bracket and the power tool, the process of lowering the carriage (3) is continued with the power tool, for which the power cord of the power tool is connected to the corresponding socket of the electrical cabinet (7) and the circuit breaker of the power tool located in the electrical cabinet (7) is turned on. The carriage (3) is lowered until it lowers onto the support brackets of the support (5). After lowering the carriage (3), turn off the power tool circuit breaker in the electrical cabinet (7), and the traverse (4) is fixed with a safety cable to the support eye (5).
