Description

Technical Field

[0002] The design and material selection of explosion-proof street lights have been specially considered to ensure safe use in flammable and explosive environments. They usually have multiple functions such as explosion-proof, anti-corrosion, and waterproof, which can ensure the normal operation of the street light system under harsh environmental conditions.

[0003] Street lamps need to be explosion-proof, mainly because they are often installed in flammable and explosive environments, such as coal mines, chemical plants, oil depots, etc. In these environments, there are explosive substances, such as flammable gases, dust, etc. When these substances are mixed with oxygen in the air, reaching a certain concentration, and there is an ignition source, an explosion may occur.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0038] See also Figure 1 - Fig.12 , an explosion-proof LED street lamp, comprising a temperature measuring tube 3, a heat conducting end 301 is fixedly connected inside the temperature measuring tube 3, a bimetallic temperature sensing element 302 is connected to the lower surface of the heat conducting end 301, and a driving shaft 303 is fixedly connected to the lower end of the bimetallic temperature sensing element 302;

[0039] A trigger component is provided at the lower end of the driving shaft 303, and a temperature adjustment component is provided on one side surface of the trigger component. After the bimetallic temperature sensing element 302 senses the temperature change and stretches or contracts, it drives the driving shaft 303 to rise or fall, so as to drive the trigger component to slide and adjust its position, so as to trigger the temperature adjustment component to connect different temperature adjustment means to increase or decrease the temperature of the street lamp.

[0040] The present invention transmits the temperature inside the street lamp to the bimetallic temperature sensing element 302 by setting a temperature measuring tube 3. The bimetallic temperature sensing element 302 senses the temperature inside the street lamp in real time. When the temperature is moderate, the trigger component is in the locked position, and the street lamp relies on non-powered means to control the temperature. When the temperature rises, the bimetallic temperature sensing element 302 expands and elongates to make the drive shaft 303 drop, and drives the trigger component to leave the locked position and connect with the sliding trigger temperature regulating component. The temperature regulating component has different temperature regulating means in different gears. Different temperature regulating means are used for different temperatures, so that the street lamp can be cooled efficiently and energy-savingly. When the temperature drops to a very low level, especially In extremely cold climates, street lamps may need to be preheated to ensure that they can start and work normally at low temperatures. At this time, the bimetallic temperature sensing element 302 contracts to make the temperature regulating component reach the heating gear, thereby heating the street lamps to enable them to operate normally. In cold seasons, ice and snow may accumulate on street lamps. By heating up, the accumulation of ice and snow on the lamps can be reduced, and the formation of icicles can be prevented. That is, street lamps can operate normally in extreme climates, and the performance and reliability of street lamps in low temperature environments can be improved. Preheating can reduce material fatigue caused by rapid temperature changes, thereby extending the service life of street lamp components.

[0047] Specifically, when the trigger block 403 moves inward to recover, the terminal 507 has no resistance force. At this time, the recovery spring 503 that was originally inserted and compressed by the terminal 507 begins to recover, releasing energy to push the terminal 507 out, so that the terminal 507 slides back to the initial position again.

[0048] Furthermore, the positions of the trigger slot 407, the wiring terminal 507, the wiring hole 501, the recovery plate 502 and the recovery spring 503 all correspond to each other, and there are four trigger slots 407, the wiring terminals 507, the wiring holes 501, the recovery plates 502 and the recovery springs 503, which are arranged in sequence from top to bottom. The topmost wiring terminal 507 is farthest from the second wiring terminal 507 from top to bottom, and the initial position of the wiring terminal 507 is also located between the two. The distances between the three wiring terminals 507 at the bottom are different depending on the temperature range to be controlled.

[0051] As a further preferred scheme in the embodiment of the present invention, a second connecting rod 206 is fixedly connected to the lower surface of the adjustment block 4, one end of the second connecting rod 206 is rotatably connected to the first connecting rod 205, one end of the first connecting rod 205 is rotatably connected to a connecting bent bar 204, one end of the connecting bent bar 204 is rotatably connected to a second connecting bar 203, a heat dissipation window 2 is provided on the side surface of the explosion-proof seat 102, one side surface of the second connecting bar 203 is slidably connected to one side surface inside the heat dissipation window 2, the other side surface of the second connecting bar 203 is rotatably connected to the first connecting bar 202, one end of the first connecting bar 202 is rotatably connected to a heat dissipation grid 201, and when the internal temperature of the street lamp rises, the adjustment block 4 moves downward, driving the first connecting rod 205 to lift the second connecting bar 203, so that the second connecting bar 203 slides and drives the heat dissipation grid 201 to rotate and open.

[0052] Furthermore, there are eleven groups of heat dissipation grids 201 and first connecting strips 202, which are evenly arranged on one side of the heat dissipation window 2 from top to bottom, and there are two first connecting strips 202 in each group, which are mirror-symmetrical about the mid-perpendicular line of the heat dissipation grid 201, and there are two second connecting strips 203, which are mirror-symmetrical about the mid-perpendicular line of the heat dissipation grid 201.

[0053] Specifically, one of the second connecting strips 203 is connected to the connecting bent strip 204. Initially, the heat dissipation grille 201 is closed to prevent external foreign matter or dust from entering the interior of the street lamp. When the temperature rises, the adjustment block 4 moves downward to drive the heat dissipation grille 201 to rotate and open. Depending on the temperature, the heat dissipation grille 201 opens at different angles to achieve stepped heat dissipation.

[0054] As a further preferred solution in the embodiment of the present invention, a semiconductor refrigeration plate 6 is provided at the lower end of the heat sink 107, a heat pipe 601 is connected to one side surface of the semiconductor refrigeration plate 6, a heat pipe 601 is connected to the side surface of the heat pipe 601, and a heat dissipation fin 602 is provided on one side surface of the heat dissipation fin 602.

[0055] As a further preferred scheme in the embodiment of the present invention, a cooling tube ring 7 is provided inside the heat sink 107, and the lower end of the cooling tube ring 7 is connected to a liquid outlet pipe 701 and a liquid return pipe 702. A cooler 703 is provided on the outer surface of the heat sink 107, and one end of the liquid outlet pipe 701 and one end of the liquid return pipe 702 both pass through the side surface of the heat sink 107 and are connected to the cooler 703.

[0056] As a further preferred solution in the embodiment of the present invention, a resistance heating coil 8 is wound around the outer surface of the wiring base 108 .

[0057] Specifically, the resistance heating coil 8 is electrically connected to the first terminal 507 at the top through a wire, the heat dissipation fan 603 is electrically connected to the second terminal 507 through a wire, the cooler 703 is electrically connected to the third terminal 507 through a wire, and the semiconductor refrigeration plate 6 is electrically connected to the fourth terminal 507 through a wire. Initially, the street lamp relies on the heat pipe 601 and the heat dissipation fins 602 that do not require electricity to dissipate heat and maintain temperature balance. Thereafter, depending on the temperature, the heat dissipation fan 603, the cooler 703 circulates the coolant, and the semiconductor refrigeration plate 6 is used to cool the temperature, and the resistance heating coil 8 is relied on for preheating and heating.

[0058] In the present invention, when the street lamp is working, the adjustment block 4 is located at the initial position, and the temperature balance is maintained by heat dissipation of the heat pipe 601 and the heat dissipation fins 602 without power supply. At this time, the reset spring 405 shrinks in the adjustment block 4, and the trigger block 403 contacts the surface of the trigger plate 406. The temperature measuring tube 3 transfers the temperature inside the street lamp to the bimetallic temperature sensing element 302. The bimetallic temperature sensing element 302 senses the temperature inside the street lamp in real time. When the temperature rises, the bimetallic temperature sensing element 302 expands and elongates to make the driving shaft 303 descend. The descending of the driving shaft 303 drives the adjustment block 4 to slide. When the adjustment block 4 slides to the second limit groove 401, the reset spring 405 returns to its original state and releases energy to trigger the trigger block 40 3 pops up, and at the same time, under the sliding action of the reset inclined groove 404, the trigger block 403 passes through the second limiting groove 401 and moves outward, and the limiting strip 402 slides to the limit on the second limiting groove 401, and the outermost end is stuck at one end of the adjusting block 4 to limit the extension length of the trigger block 403. At the same time, after the trigger block 403 moves outward and extends, it will touch the second wiring terminal 507 and drive the second wiring terminal 507 to slide toward the side of the wiring board 5 until the trigger block 403 extends to the maximum, and the second wiring terminal 507 slides into the wiring hole 501, so that the second wiring terminal 507 is energized, so that the cooling fan 603 is running. When the temperature continues to rise, the reset inclined groove 404 Under the action, the trigger block 403 is able to move inward to recover and continue to resist the surface of the trigger plate 406, and when the trigger block 403 moves inward to recover, the second terminal 507 has no resistance. At this time, the recovery spring 503, which was originally inserted and compressed by the second terminal 507, begins to recover, releasing energy to push the second terminal 507 out, so that the second terminal 507 slides back to the initial position again, and then the adjustment block 4 continues to slide downward, and when it slides to the third or fourth limit groove 401, the previous operation is repeated to make the cooler 703 energized and circulated to produce coolant or semiconductor refrigeration sheet 6 for cooling, and then different temperature adjustment means are used to reduce the temperature according to the temperature change. Temperature; when the temperature drops to a very low level, especially in extremely cold climates, the street lamp may need to be preheated to ensure that it can start and work normally at low temperatures. At this time, the bimetallic temperature sensing element 302 contracts so that the first terminal 507 is powered, and the resistance heating coil 8 is powered to heat the street lamp, so that the street lamp can operate normally. In cold seasons, ice and snow may accumulate on the street lamp. The heating of the resistance heating coil 8 can reduce the accumulation of ice and snow on the lamp and prevent the formation of icicles, that is, the street lamp can work normally in extreme climates, improve the performance and reliability of the street lamp in low temperature environments, and preheating can reduce material fatigue caused by rapid temperature changes, thereby extending the service life of street lamp components;When the temperature rises and the adjustment block 4 slides downward, the first connecting rod 205 is driven to rotate, and the rotation of the first connecting rod 205 drives the connecting curved bar 204 to rotate, and the connecting curved bar 204 drives the second connecting bar 203 to slide upward, so that the heat dissipation grid 201 is rotated and opened, and the heat dissipation grid 201 is opened at different angles according to different temperatures, so as to achieve step-type heat dissipation, and the second connecting bar 203 can only rise but not fall when it is in the initial position, so that in a cold environment, the heat dissipation grid 201 is in a normally closed state, thereby improving the heating effect and heat preservation performance.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
