Description

Technical Field

[0001] This application relates to the technical field of environmental monitoring, and particularly to a warning light and a production environment temperature monitoring system having the warning light. Background Art

[0002] Warning lights are widely used in modern factories, equipment, marine vessels, and industrial environments. The dazzling light of warning lights does not serve a decorative purpose. A warning light is a safety indicator light that can remind people of issues that need attention by flashing or continuously emitting light. When in use, warning lights convey different information through different colors, flashing frequencies, and modes. Among them, when a warning light flashes, it generally achieves this by controlling the current. A warning light usually consists of two electrodes, namely the positive electrode and the negative electrode. When current passes through the two electrodes, electrons are generated inside the lamp, and these electrons will excite the fluorescent layer of the lamp to emit light. When the current is interrupted or changes, the brightness of the lamp will also change accordingly. Therefore, by controlling the on-off state of the current, the flashing of the warning light can be achieved.

[0003] However, this method of achieving the flashing effect by controlling the on-off of the current in the lamp body will affect its service life. The main reason is that each switch requires more energy consumption, resulting in faster wear. This wear is very significant for lamps, especially for those that have been used for a considerable period of time. Frequent switch operations may accelerate their aging process and shorten their service life. Utility Model Content

[0007] A second light-shielding cover is sleeved on the outside of the first light-shielding cover. The same number of second light-transmitting holes as the first light-transmitting holes are evenly opened on the peripheral side of the second light-shielding cover;

[0008] The light emitted by the light source main body can only shine into the external environment when the second light-transmitting holes and the first light-transmitting holes are aligned one by one;

[0009] The bottom of the second light shield is connected to the driving unit, and the driving unit can drive the second light shield to rotate around its axis outside the first light shield.

[0010] Further, a first opening is provided at the top of the second light shield, and the inner diameter of the first opening is equal to the diameter of the top plate of the first light shield.

[0011] Further, the driving unit includes a driving disc located directly below the second light shield, and a plurality of fixing rods are connected between the driving disc and the lower end of the second light shield;

[0012] A rotating sleeve is fixedly installed at the middle position of the driving disc, and a driving motor is provided directly below the driving disc; the output shaft of the driving motor sequentially passes through the driving disc and the rotating sleeve upward, and the output shaft of the driving motor is fixedly connected to both the driving disc and the rotating sleeve;

[0013] A motor housing is sleeved outside the driving motor, the output shaft of the driving motor passes through the top of the motor housing and is rotatably connected therebetween, and the bottom of the driving motor is fixedly installed on the motor housing; a second mounting plate is fixedly installed below the motor housing.

[0014] Further, a second opening is provided at the bottom of the second light shield, the second opening is sleeved outside the lower end of the transparent protective cover and is rotatably connected therebetween, and a heat dissipation unit is installed in the area inside the plurality of fixing rods at the bottom of the transparent protective cover.

[0015] Further, the heat dissipation unit includes a heat dissipation fan, the heat dissipation fan is fixedly connected to the bottom plate of the transparent protective cover, a first gear is fixedly connected to the lower end of the power shaft of the heat dissipation fan, a second gear is meshed with one side of the first gear, and the center position of the lower side of the second gear is fixedly connected to the upper end of the output shaft of the driving motor.

[0016] Further, the number of the heat dissipation units is two, and the two heat dissipation units are symmetrically arranged about the output axis of the driving motor below the transparent protective cover.

[0017] Further, the diameter of the second gear is larger than the diameter of the first gear.

[0018] Further, a metal heat conducting plate is installed at the bottom of the transparent protective cover, and the air inlets of the two heat dissipation fans are both directed at the metal heat conducting plate.

In this way, when the driving unit rotates continuously with the second light shield, an alternating light and dark flashing effect will appear in the external environment, thereby serving as a warning to the workers in the production area. Compared with the prior art, the flashing effect of the light produced by the warning light in the present application when working does not come from the frequent on and off of the current of the lamp body, but is achieved through a simple mechanical principle, which can effectively prevent the warning light from aging rapidly and shortening its service life due to frequent on and off of the current.

Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts also belong to the scope of protection of the present application.

[0032] As Figures 1-4 shown, a warning light disclosed in the present application includes a light source main body 2 with a transparent protective cover 1 provided on the outside. A first light-shielding cover 3 is sleeved on the outside of the transparent protective cover 1. The bottom of the first light-shielding cover 3 is fixedly connected to the bottom of the transparent protective cover 1. A plurality of first light-transmitting holes 4 are evenly formed on the circumferential side of the first light-shielding cover 3, and there is an interval between adjacent first light-transmitting holes 4;

[0033] A second light-shielding cover 5 is sleeved on the outside of the first light-shielding cover 3. A plurality of second light-transmitting holes 6 equal in number to the first light-transmitting holes 4 are evenly formed on the circumferential side of the second light-shielding cover 5;

[0034] The light emitted by the light source main body 2 can only shine into the external environment when the second light-transmitting holes 6 and the first light-transmitting holes 4 are aligned one by one;

[0035] The bottom of the second light-shielding cover 5 is connected to the driving unit 7, and the driving unit 7 can drive the second light-shielding cover 5 to rotate around its axis on the outside of the first light-shielding cover 3.

[0036] In the above embodiments, since the warning light is usually activated only when an abnormal situation occurs, the light source body 2 of the present application can select a prominent red light source, which is convenient for quickly attracting the attention of nearby workers. The transparent protective cover 1 outside the light source body 2 protects the light source body 2 while ensuring that the light emitted by the light source body 2 can pass through smoothly during operation.

[0037] The first light shielding cover 3 and the second light shielding cover 5 of the present application are both made of preferably light-impermeable plastic. In this way, for the light emitted by the light source body 2 to shine into the external environment, it is only possible when the first light-transmitting holes 4 on the first light shielding cover 3 and the second light-transmitting holes 6 on the second light shielding cover 5 are aligned one by one. The second light shielding cover 5 of the present application is connected to a driving unit 7, and the driving unit 7 can drive the second light shielding cover 5 to continuously rotate outside the first light shielding cover 3. During the rotation of the second light shielding cover 5, the second light-transmitting holes 6 on it will periodically communicate with the first light-transmitting holes 4 on the first light shielding cover 3. In this way, the light emitted by the light source body 2 in the transparent protective cover 1 will periodically shine into the external production site environment. When the interval time between the brightness and darkness of the light in the external environment is short, a flashing effect can occur, thus playing a warning role for nearby production workers so that they can take corresponding measures in time. Compared with the prior art, the flashing effect of the warning light in the present application during operation does not come from the frequent on-off of the lamp body current, but is achieved through a simple mechanical principle, which can effectively prevent the warning light from accelerating aging and shortening its service life due to frequent on-off of the current.

[0038] Further, as Figure 1 and Figure 2 shown, the top of the second light shielding cover 5 is provided with a first opening 8, and the inner diameter of the first opening 8 is equal to the diameter of the top plate of the first light shielding cover 3. The top plate of the first light shielding cover 3 is located in the first opening 8 at the top of the second light shielding cover 5; the middle position of the top plate of the first light shielding cover 3 is fixedly connected to a first mounting plate 10 through a hollow suspension rod 9.

[0039] In the above embodiments, the first opening 8 provided at the top of the second light shielding cover 5 of the present application can expose the top plate of the first light shielding cover 3 to the environment. In this way, after the first mounting plate 10 is installed at a specified position, the first mounting plate 10 can provide a stable supporting force for the first light shielding cover 3, the transparent protective cover 1, the light source body 2, etc. through the hollow suspension rod 9, and the second light shielding cover 5 will not be affected by the hollow suspension rod 9 on the first light shielding cover 3 during rotation. In addition, when the hollow suspension rod 9 of the present application is in use, the internal space thereof can be used to lay the cables required for the operation of the light source body 2, so as to make the overall appearance of the device neat and beautiful.

[0040] Further, as Figure 1 and Figure 3As shown, the driving unit 7 includes a driving disc 71 located directly below the second light-shielding cover 5, and a plurality of fixing rods 72 are connected between the driving disc 71 and the lower end of the second light-shielding cover 5;

[0041] A rotating sleeve 73 is fixedly installed at the middle position of the driving disc 71, and a driving motor 74 is provided directly below the driving disc 71; the output shaft of the driving motor 74 sequentially penetrates through the driving disc 71 and the rotating sleeve 73 upward, and the output shaft of the driving motor 74 is fixedly connected to both the driving disc 71 and the rotating sleeve 73;

[0042] A motor housing 75 is sleeved outside the driving motor 74, the output shaft of the driving motor 74 penetrates through the top of the motor housing 75 and is rotatably connected therebetween, and the bottom of the driving motor 74 is fixedly installed on the motor housing 75; a second mounting plate 76 is fixedly installed below the motor housing 75.

[0043] In the above embodiments, the driving motor 74 installed in the motor housing 75 of the present application is fixedly installed at a specified position through the second mounting plate 76 below the motor housing 75. In this way, when the driving motor 74 is working, its output shaft can stably drive the driving disc 71 and the rotating sleeve 73 fixedly connected thereto to rotate synchronously. The rotating sleeve 73 can increase the contact area between the output shaft of the driving motor 74 and the driving disc 71, and improve the stability during their rotation. Since the driving disc 71 and the lower end of the second light-shielding cover 5 are connected by a plurality of fixing rods 72, after the driving motor 74 is started, it can use its output shaft to drive the second light-shielding cover 5 to continuously rotate outside the first light-shielding cover 3 through the driving disc 71, so as to make the light emitted by the light source body 2 achieve a flashing effect. In actual use, a motor speed regulator is added to the driving motor 74, and the flashing frequency of the lamp tube can also be controlled by controlling the rotation speed of the driving motor 74, effectively improving the flexibility during use.

[0044] Further, as Figure 2 and Figure 5 shown, a second opening 11 is provided at the bottom of the second light-shielding cover 5. The second opening 11 is sleeved outside the lower end of the transparent protective cover 1 and is rotatably connected therebetween. A heat dissipation unit 12 is installed in the area inside the plurality of fixing rods 72 at the bottom of the transparent protective cover 1.

[0045] In the above embodiments, the light source body 2 of the warning lamp will generate a certain amount of heat during the working process. If the heat of the warning lamp cannot be dissipated in time, it will not only affect its service life but also may cause damage to related electronic components. The present application makes use of the space between the lower end of the transparent protective cover 1 and the driving disc 71. The installed heat dissipation unit 12 can reduce the temperature of the warning lamp by accelerating the air flow speed around the device, so as to ensure that the warning lamp of the present application can operate stably for a long time and extend the service life.

[0046] Further, as Figure 1 and Figure 5 shown, the heat dissipation unit 12 includes a heat dissipation fan 121, which is fixedly connected between the bottom plate of the transparent protective cover 1. A first gear 122 is fixedly connected to the lower end of the power shaft of the heat dissipation fan 121. A second gear 123 is engaged with one side of the first gear 122. The center position on the lower side of the second gear 123 is fixedly connected to the upper end of the output shaft of the driving motor 74.

[0047] In the above embodiments, after the upper end of the output shaft of the driving motor 74 of the present application passes through the driving disc 71 and the rotating sleeve 73 upward, it also extends a certain distance above the upper end of the rotating sleeve 73. The second gear 123 installed at the upper end of the output shaft of the driving motor 74 can rotate with its output shaft when the driving motor 74 works. The side of the second gear 123 is engaged with the first gear 122, and the center of the first gear 122 is connected to the power shaft of the heat dissipation fan 121. In this way, the heat dissipation fan 121 can be driven to work synchronously when the driving motor 74 works. Since the light source main body 2 will light up when there is an abnormal situation in the production area, the driving motor 74 will be started synchronously to drive the first light shielding cover 3 to rotate outside the second light shielding cover 5 to achieve the warning effect of flashing lights. When the driving motor 74 works, the heat dissipation fan 121 will rotate synchronously, so that a good heat dissipation effect can be obtained in time and continuously after the warning light of the present application is started. Some through ventilation holes can also be uniformly arranged along the circumference on the first gear 122, so as to reduce the air resistance discharged by the first gear 122 to the heat dissipation fan 121.

[0048] Further, as Figure 1 and as Figure 5 shown. The number of the heat dissipation units 12 is two, and the two heat dissipation units 12 are symmetrically arranged about the output axis of the driving motor 74 below the transparent protective cover 1.

[0049] In the above embodiments, the heat dissipation capacity of the light source main body 2 can be improved by increasing the number of the heat dissipation units 12, and the heat dissipation effect can be made more uniform by symmetrically arranging the two heat dissipation units 12 in the above manner.

[0050] Methods such as increasing the number and area of the heat dissipation fins, increasing the rotation speed of the fan, and reducing the power of the LED lamp beads can improve the heat dissipation effect, so as to ensure that the warning light can work normally in a high-temperature environment. In addition, regular inspection and maintenance are also the keys to maintaining the stable performance of the warning light in a high-temperature environment. By regularly cleaning the heat dissipation fins, replacing the lamp beads and other maintenance measures, the long-term stable operation of the warning light in a high-temperature environment can be ensured.

[0051] Further, as Figure 5 shown, the diameter of the second gear 123 is larger than the diameter of the first gear 122.

[0052] In the above embodiments, the diameter of the second gear 123 is larger than that of the first gear 122. In this way, when the output shaft of the driving motor 74 rotates one circle, the number of circles that the second gear 123 drives the first gear 122 to rotate is more than one circle, so that the rotation speed of the fan blades in the radiator fan can be increased, and accordingly, the heat dissipation effect can be improved, thereby ensuring that the warning light of the present application can work normally in a high-temperature environment.

[0053] Furthermore, as Figure 5 shown, a metal heat conduction plate 13 is installed at the bottom of the transparent protective cover 1, and the air inlets of the two radiator fans 121 are both facing the metal heat conduction plate 13.

[0054] In the above embodiments, the metal heat conduction plate 13 installed at the bottom of the transparent protective cover 1 can improve the heat export efficiency inside it, so that the radiator fans 121 in the lower radiator unit 12 can quickly dissipate the heat in the transparent protective cover 1. The bracket for installing the radiator fan 121 on the outer shell of the radiator fan 121 can be installed on the metal heat conduction plate 13, or can be installed in the area outside the metal heat conduction plate 13 at the bottom of the transparent protective cover 1, as long as the air inlet of the radiator fan 121 faces the metal heat conduction plate 13 to ensure that the heat can be drawn away when the radiator fan 121 works.

[0055] Furthermore, transparent plastic plates are installed on both the first light-transmitting hole 4 and the second light-transmitting hole 6.

[0056] In the above embodiments, the transparent plastic plates provided in the first light-transmitting hole 4 and the second light-transmitting hole 6 can not only ensure that the light can pass through smoothly, but also ensure the airtightness inside them, preventing dust from entering and making it inconvenient for subsequent cleaning.

[0057] As Figure 6 shown, the present application also provides a production environment temperature monitoring system. As Figure 6 shown, it includes a temperature sensor, a buzzer, a normal temperature warning light and a high temperature warning light that are electrically connected together, and the high temperature warning light is the warning light as described above.

[0058] In the above embodiments, in the production site, some important equipment is often placed in a toughened glass room. The temperature requirements for these equipment rooms are usually very high. Generally, for temperature monitoring, it is either that the inspection personnel go to the room regularly to check the temperature, or the remote temperature points are transmitted to the centralized monitoring room for special personnel to monitor. Inevitably, these all require special personnel to conduct inspections on the environmental temperature. This method has certain limitations. If the special personnel do not conduct inspections in time or do not discover temperature anomalies in the monitoring room in time, it will increase the risk of damage to these important equipment.

[0059] This application installs a temperature probe in a tempered glass room to detect the temperature of the environment around important equipment. When the ambient temperature in the room is normal, the temperature sensor can transmit the signal to the normal temperature warning light, so that the normal temperature warning light lights up; when the temperature in the room is high, the temperature sensor can transmit the signal to the high temperature warning light and the buzzer, so that the high temperature warning light lights up, and the buzzer sounds so that the workers in the workshop can also find the abnormal temperature in the room in time and take corresponding measures. The high temperature warning light is the warning light in this application, and when it lights up, it can emit a flash to improve the warning effect to people around.

[0060] In actual use, a blue bulb can be selected for the normal temperature warning light, and a red bulb can be selected for the high temperature warning light. When the blue bulb continues to glow, it means that the temperature in the tempered glass room is in a normal state below 37°C. Since the indoor temperature is normal in most cases, the blue bulb needs to be lit for a long time. Therefore, a bulb with an ordinary structure can be selected for the blue bulb without flashing frequently to avoid interfering with the normal work of the workers in the workshop; the red bulb is lit, which means that the ambient temperature monitored by the temperature sensor is above 37°C. This situation is an abnormal situation. Therefore, a flashing warning light in this application is used, so that any worker within sight of the room can judge whether the temperature of the equipment is safe or unsafe by the light, so as to quickly take corresponding measures to protect the safety of the equipment.

[0061] The implementation principle of the warning light of the present application is: when the warning light of the present application is in use, once an abnormality occurs at the production site, the circuit of the lamp source main body 2 starts to emit light, and the driving motor 74 in the driving unit 7 starts synchronously, driving the second light blocking cover 5 to start and continuously rotate on the outside of the first light blocking cover 3. When the second light blocking cover 5 rotates on the outside of the first light blocking cover 3, the first light transparent holes 4 and the second light transparent holes 6 on the two will periodically align and stagger. When the second light transparent holes 6 on the second light blocking cover 5 and the first light transparent holes 4 on the first light blocking cover 3 are aligned, the light emitted by the lamp source main body 2 will shine into the external environment. When the second light transparent holes 6 on the second light blocking cover 5 and the first light transparent holes 4 on the first light blocking cover 3 are staggered, the light emitted by the lamp source main body 2 will be blocked and cannot shine into the external environment. In this way, when the driving unit 7 rotates continuously with the second light blocking cover 5, an alternating light and dark flashing effect will appear in the external environment, thereby serving as a warning to the workers in the production area. During the operation of the driving motor 74, the second gear 123 thereon can also drive the first gear 122 in the heat dissipation units 12 on both sides to rotate, so that the cooling fans 121 in the two heat dissipation units 12 can work synchronously, thereby dissipating heat for the entire device and improving the stability and safety of its working process.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
