[0021] like Figures 1 to 5 As shown, the utility model relates to a lighting equipment protection device for urban lighting projects, including a lighting base 1, which is arranged on the ground, a lighting pole 2 is installed on the top of the lighting base 1, a plurality of extension frames 3 are arranged on the upper half of the lighting pole 2, and a lighting seat 4 is connected to the end of the extension frame 3, the extension frame 3 is used to support the lighting seat 4, a lighting light source 5 is arranged inside the lighting seat 4, a threading cavity is arranged in the center of the lighting seat 4, the threading cavity is electrically connected to the lighting light source 5, and its power supply is through the municipal power supply, a protective cover 6 is fixed on the top of the lighting light source 5, the protective cover 6 is designed to be detachable by bolts, a lighting partition 7 is installed inside the protective cover 6, heat dissipation ports are opened on the lighting partition 7 and the protective cover 6, a lighting insulation structure 8 for blocking the heat dissipation ports is arranged inside the lighting partition 7, and the lighting insulation structure 8 includes a lighting light source in the center A core rod 801 and a ring sleeve 10 are provided on the upper half of the outer periphery of the central rod 801 of the lighting source for limiting sliding. The limiting sliding is achieved in the form of a slide groove and a slider, so that the central rod 801 of the lighting source can only move up and down. A connecting rod 11 is connected between the outer periphery of the ring sleeve 10 and the inner wall of the lighting partition 7. The central rod 801 of the lighting source is located at the center of the lighting partition 7. An outer protective ring 802 of the lighting source is provided on the outer periphery of the central rod 801 of the lighting source. A plurality of extension rods 803 are installed between the outer protective ring 802 of the lighting source and the central rod 801 of the lighting source. A plurality of ventilation pipes 804 fixed to the heat dissipation port on the protective outer cover 6 are attached to the outer periphery of the extension rod 803. A plurality of long rods 805 are installed at the bottom of the outer protective ring 802 of the lighting source. The bottom of the long rod 805 is connected to a plug 806 that fits the heat dissipation port on the lighting partition 7.
[0022] Working principle: when in a static state, the plug 806 fits with the heat dissipation port on the lighting baffle 7, and the outer protective ring 802 of the lighting source fits with the ventilation pipe 804, thereby isolating the lighting baffle 7 and the protective outer cover 6 from each other, thereby achieving sealing, and performing internal insulation, which is suitable for use in cold winter environments. When it is a high temperature environment in summer, the center rod 801 of the lighting source rises, driving the plug 806 and the outer protective ring 802 of the lighting source to move upward, achieving internal air flow, allowing it to dissipate heat, and further avoiding high temperature and high cold environments inside, protecting the internal electronic components, and extending their service life.
[0023] It should be noted that the ventilation pipe 804 is designed to be tilted downward, which can prevent rainwater from entering through natural gravity.
[0024] In the embodiment of the utility model, in order to realize automatic control of the internal space, a self-control structure 9 is provided at the center of the lighting partition 7 for driving the lighting insulation structure 8 to rise and fall by using heat energy. The self-control structure 9 includes a heat-conducting rod 901 for absorbing the heat of the lighting light source 5. The heat-conducting rod 901 is a device for conducting heat, and is usually made of a material with good thermal conductivity, such as copper, aluminum and other metals. Its working principle is based on heat conduction, that is, heat is automatically transferred from a high-temperature area to a low-temperature area. When one end of the heat-conducting rod 901 contacts a high-temperature object and the other end contacts a low-temperature object, the heat will be transferred from the high-temperature end along the heat-conducting rod 901. At the low-temperature end, the heat-conducting rod 901 is in contact with or nearly in contact with the lighting source 5 and the top end passes through the lighting baffle 7. A bimetallic strip 92 composed of two metal sheets with different thermal expansion coefficients is bonded to the top of the heat-conducting rod 901. The bimetallic strip 92 includes an outer ring 903 fixed to the lighting baffle 7 and an extended tentacle 904. The extended tentacle 904 protrudes from the inner wall of the outer ring 903 and is in contact with the heat-conducting rod 901. The end of the extended tentacle 904 is located directly below the center rod 801 of the lighting source, and a convex top ball 905 in contact with the center rod 801 of the lighting source is installed on the end of the extended tentacle 904.
[0025] The working principle is that the heat is conducted to the other end through the heat conducting rod 901. Since the other end is in contact with the bimetallic strip 92, it can be heated. When the heat reaches a certain level and needs to be dissipated, the extended tentacle 904 will bend and bounce, causing the convex top ball 905 to move upward, pushing the center rod 801 of the lighting source to rise, thereby realizing automatic lifting and heat dissipation. After the temperature is dissipated, the internal temperature gradually decreases, and the extended tentacle 904 will gradually return to a round shape and be sealed and heat-insulated again, thereby utilizing the heat of the light source itself to realize automatic opening and closing of the temperature hole.
[0026] It is worth mentioning that its self-controlled temperature can be adjusted according to the conditions of the area of use, as follows.
[0027] Changing the material combination of the bimetallic strip 92: Different metal combinations have different thermal expansion coefficients. The bounce temperature can be adjusted by selecting a suitable metal combination. For example, if two metals with a larger difference in thermal expansion coefficients are selected to make the bimetallic strip 92, the deformation degree of the bimetallic strip 92 will be greater under the same temperature change, and the bounce temperature can be reduced within a certain range; conversely, if a metal combination with a smaller difference in thermal expansion coefficients is selected, the bounce temperature will increase.
[0028] Changing the size and shape of the bimetallic strip 92: The length, width, thickness and other sizes and shapes of the bimetallic strip 92 will affect its thermal response characteristics. Generally speaking, the thinner the bimetallic strip 92 is, the more sensitive it is to temperature changes, and the bounce temperature may be lower; increasing the length of the bimetallic strip 92 may also make it more sensitive to temperature changes and more likely to bounce at lower temperatures. At the same time, changing the shape of the bimetallic strip 92, such as making it into a more complex curved shape, can also adjust its thermal response characteristics, thereby changing the bounce temperature.
[0029] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
