1. The high pole lamp heat has not been retired. After the inner ring road of Guangzhou City was installed with more than 80 bases in the early years, the road lighting construction of Guangyuan East Road was opened last year. There are more than 140 bases for high pole lights. The unilateral lighting of the road, especially the use of high pole lights in the urban area, is debatable.
2, in view of the current "low price" play standard, and the management of the standard of the standard in a certain area of ​​the lack of technology, resulting in low-price successful bidders forced to cut corners, the phenomenon of poor filling. For example, the price of a 25-meter high pole lamp, the simple type is only tens of thousands of yuan, and the function is complete, the technology content is high, and it meets the industry standard and needs more than 100,000 yuan. If the designer does not specify the technical conditions or requirements, the low-price winning bidder will be counted as a simple type. I think that the high pole light group of the first and second lighting projects of Guangyuan East Road has doubts about this problem.
Therefore, for bidding, there is a lot of loopholes in the principle of “lower priceâ€. Investors seem to save a sum of money, but this can only be temporary, and the subsequent “aftercare†does not know how many times of “savings†to be posted to make the lighting facilities work.
The common problems with the "simple" high pole lights are:
(1) There is no guarantee for the safety of key parts; for example, the lifted lamp panel has neither support (locking) nor anti-drop device or overload protection mechanism. In other words, it does not meet the requirements of the current industry standard "Technical Conditions for High-Pole Lighting Facilities" (CCJ/T3067).
(2) The speed of the lamp tray is slow. The elevation speed of the high pole lamp panel of Guangyuan East Road is 0.7 meters per minute. It takes more than one hour for the 30 meter high pole lamp to lift the lamp panel. For example, it takes two hours to complete with the loading and unloading mobile motor.
(3) Most of the lifting and hoisting mechanisms are “patch-and-makeâ€, that is, a gearbox is purchased and connected to the motor, and a roller is added. It has been found that the scattered frame, the line speed does not match, the gear teeth are damaged, the drop can not be lifted, and the booming and banging phenomenon is common.
3. The support (latching) mode of the lift-type lamp panel is often difficult to hang and take off due to technical differences in design, processing, installation and operation personnel. In my opinion, what American and French automatic hanging hooks (shafts) are not ideal, the most practical and simple structure, easy to operate is the "automatic screw-in trough support (unloading) device".
4, the humid climate of the south, it is not suitable to use the built-in motor of the light pole, to move (loading) type as well.
5, engage in road lighting design, such as the use of high pole lights, must have detailed technical conditions. Engage in bidding, do not ignore the loopholes that may exist in this regard.
6, high-lift lifting lamp, its lifting speed is too fast and too slow, it is recommended that its lifting speed is in the range of 2 to 5 meters (currently "standard" only upper limit and no lower limit)
The author of this article has repeatedly submitted manuscripts on high pole light technology (mainly in mechanical aspects), operation management and safe use to the "Outdoor Lighting" lamp publication. Today, I have combined with more than 500 bases in Guangzhou (including more than 100 non-street light department management). I have seen the construction and operation management of various types of high-light poles in domestic and imported forms.
