Description

Technical Field

[0002] As a lighting device designed for flammable and explosive environments, explosion-proof lamps are mainly used in industries such as petroleum, chemical industry, and coal mining. Its core feature is that it can work normally in dangerous environments without generating electric sparks to cause explosions. However, there are still some problems with the actual application of explosion-proof lamps on the market. First of all, in some harsh environments such as particularly high temperatures, if the heat generated by explosion-proof lamps during operation cannot be effectively dissipated, it will not only shorten the service life of the lamp, but also increase the risk of safety accidents due to excessive temperature. Although certain heat dissipation measures have been taken for explosion-proof lamps on the market, such as increasing the heat dissipation area and using materials with better thermal conductivity, these methods are often difficult to meet actual needs in the case of long-term high-load operation, resulting in a decline in lamp performance and increased safety hazards. Some explosion-proof lamps try to cool and dissipate heat through liquids, but this method requires regular spraying of liquids on the explosion-proof lamps, which means that too much liquid can easily enter the interior of the lamp through threading holes and other parts, which may cause safety hazards such as short circuits and leakage. Secondly, when explosion-proof lamps are exposed to liquid for a long time or with high intensity, the threading holes and other parts are prone to become channels for water to penetrate, causing liquid to enter the interior of the lamps, increasing safety hazards. Whether it is heat dissipation through liquid or rain in the natural environment, these problems will affect the safety and reliability of explosion-proof lamps in actual applications.

[0022] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-4 A mounting shell is shown, comprising a shell body 1, wherein one side of the shell body 1 is provided with a raised waterproof step 2, a plurality of fins 3 extending in the raised direction of the waterproof step 2, a plurality of liquid storage areas 4 surrounded by the fins 3 and the waterproof step 2, and a drain port 5 for draining water from the liquid storage area 4, the waterproof step 2 is provided with at least one threading hole 6, and the full water level of the liquid storage area 4 is lower than the height of the waterproof step 2 to prevent liquid from entering the threading hole 6.

[0024] In the utility model, the shell body 1 is provided with a plurality of liquid storage areas 4 formed by setting a waterproof step 2 and a plurality of fins 3. This arrangement can effectively store liquid for heat dissipation during the operation of the lamp, thereby ensuring the normal operation of the lamp in a high temperature environment; in addition, the setting of the drain port 5 ensures that excess liquid in the liquid storage area 4 can be discharged in time, so that the full water level of the liquid storage area 4 is always lower than the waterproof step 2, avoiding the risk of liquid overflowing and entering the interior of the lamp through the threading hole 6. This arrangement improves the waterproof performance of the lamp and ensures its reliability and safety in harsh environments.

[0025] The utility model realizes efficient heat dissipation and reliable waterproof performance by arranging a waterproof step 2 and a plurality of fins 3 on the shell body 1 to enclose a plurality of liquid storage areas 4. Specifically, a raised waterproof step 2 is provided on one side of the shell body 1, and a plurality of fins 3 extend in the raised direction of the waterproof step 2. These fins 3 and the waterproof step 2 together enclose a plurality of liquid storage areas 4. This arrangement enables the lamp to effectively utilize these liquid storage areas 4 to store liquid for heat dissipation when working in a high-temperature environment, thereby ensuring the normal operation of the lamp in a high-temperature environment. The liquid in the liquid storage area 4 can absorb and dissipate the heat generated by the lamp during operation, thereby avoiding the problem of lamp performance degradation and increased safety hazards due to excessive temperature; further, a drain port 5 for draining the liquid storage area 4 is provided on the shell body 1. This arrangement ensures that excess liquid in the liquid storage area 4 can be discharged in time, so that the full water level of the liquid storage area 4 is always lower than the height of the waterproof step 2, thereby preventing the risk of liquid overflowing and entering the interior of the lamp through the threading hole 6, and ensuring that even under long-term or high-intensity liquid invasion, the threading hole 6 and other parts will not enter the interior of the lamp through the threading hole 6 because the water level exceeds the waterproof step 2, effectively avoiding safety hazards such as short circuit and leakage caused by liquid entering the interior of the lamp.

[0026] Further, such as Figure 1-4 A mounting shell is shown, wherein the fin 3 includes a first fin 31 located on the circumferential side of the shell body 1, and a plurality of second fins 32 connected between the waterproof step 2 and the first fin 31, the second fins 32 are distributed circumferentially along the waterproof step 2, the first fin 31, the waterproof step 2 and at least two of the second fins 32 enclose a plurality of the liquid storage areas 4, and the waterproof step 2 is located in the middle of the shell body 1.

[0027] In the utility model, the first fin 31, the waterproof step 2 and the two second fins 32 enclose a liquid storage area 4. By setting the first fin 31 and the plurality of second fins 32, a plurality of liquid storage areas 4 are enclosed. This setting allows the liquid to be separated into different liquid storage areas 4 when it enters the shell, thereby avoiding excessive accumulation in a certain area, thereby reducing the speed at which the liquid level in a single area rises. Furthermore, the second fin 32 is connected to the waterproof step 2. This setting allows the area around the waterproof step 2 to be separated into a plurality of areas, and the second fin 32 plays a drainage role, thereby avoiding excessive accumulation of liquid around the waterproof step 2, thereby effectively preventing the water level from exceeding the height of the waterproof step 2. , thereby preventing liquid from entering the interior of the shell through the threading hole 6; further, the waterproof step is located in the middle of the shell body 1. This design ensures the consistency of the size of each liquid storage area 4, and tries to ensure that the liquid storage amount of each liquid storage area 4 is the same under full load, preventing the problem of excessive hydraulic pressure on one side, and improving the stability of the entire structure; further, multiple second fins 32 are distributed circumferentially and evenly along the waterproof step 2. This arrangement can not only evenly disperse the water pressure and guide the water flow, avoid local water level being too high, but also further improve the overall structural stability of the shell; further, the second fin 32 extends along a straight line to ensure that the liquid in the liquid storage area 4 can flow better to the drain port 5 along the second fin 32.

[0028] Further, such as Figure 1-4 In the illustrated installation housing, the second fin 32 is further provided with a first connection portion 321 at one end connected to the waterproof step 2 , and the height h1 of the waterproof step 2 is higher than the height h2 of the first connection portion 321 .

[0029] The utility model makes the height h1 of the waterproof step 2 higher than the height h2 of the first connection part 321. When the liquid level rises, the liquid can flow to other liquid storage areas 4 through the first connection part 321. This arrangement makes the waterproof step 2 an effective barrier to block the water level, ensuring that even if the liquid in a certain liquid storage area 4 accumulates too quickly, the water level will not exceed the waterproof step 2 and enter the threading hole 6, thereby improving the overall waterproof performance; further, if liquid falls onto the waterproof step 2, this arrangement also ensures that the liquid automatically falls into the liquid storage area 4 due to gravity at the relatively high waterproof step 2, thereby further improving the overall waterproof performance.

[0030] Further, such as Figure 1-4An installation shell is shown, wherein the liquid storage area 4 includes a drainage area 41 close to the first fin 31, the shell body 1 includes a first shell surface 11, a transition surface 13 connected to the first shell surface 11, and a second shell surface 12 connected to the transition surface 13, the first shell surface 11 is higher than the second shell surface 12, the first shell surface 11 and the second shell surface 12 are arranged in parallel, and the first fin 31, the transition surface 13 and at least two of the second fins 32 enclose the drainage area 41.

[0031] In the utility model, the drainage area 41 is surrounded by the first fin 31, the transition surface 13 and the two second fins 32. Through the setting of the transition surface 13, the drainage area 41 is set away from the waterproof step 2 and at the lowest position of the liquid storage area 4, so that when liquid accumulates in the liquid storage area 4, the liquid can be quickly guided to the drainage area 41 away from the waterproof step 2. When too much liquid accumulates, the drainage area 41 will give priority to drainage, effectively preventing the phenomenon of excessive liquid accumulating in the liquid storage area 4 and causing the liquid level to exceed the waterproof step 2. This setting ensures that the liquid will not accumulate in the liquid storage area 4 to a height sufficient to exceed the waterproof step 2, thereby preventing the liquid from entering the threading hole 6, further improving the waterproof ability of the shell.

[0032] Further, such as Figure 1-4 A mounting shell is shown, wherein the waterproof step 2 is provided with a boss 21 on the side away from the first shell surface 11, and the boss 21 is also provided with a first threading hole 61 and a second threading hole 62 passing through the shell body 1, the first threading hole 61 is located at the center of the waterproof step 2, and the second threading hole 62 is located at the edge of the waterproof step 2.

[0033] The utility model is provided with a first threading hole 61 and a second threading hole 62, so that the user can insert different types of wires or cables into different holes according to needs. This arrangement is helpful for classifying and organizing the wires. Each threading hole 6 only passes one wire, making the wire layout clearer; further, inserting the wires separately into different threading holes 6 can effectively prevent the entanglement and mutual wear between the wires and reduce the risk of failure. This arrangement not only improves the convenience of wire management, but also reduces the wear caused by mutual friction between the wires, thereby extending the service life of the wires and further improving the safety and reliability of the equipment; further, by providing a boss 21 on the waterproof step 2 and arranging the threading hole 6 on the boss 21, the liquid that falls near the threading hole 6 can be better refluxed to the waterproof step 2 through the boss 21, and then falls into the liquid storage area 4, thereby better preventing the liquid from entering the threading hole 6.

[0034] Further, such as Figure 1-4A mounting housing is shown, wherein the height h3 of the boss 21 is higher than the height h1 of the waterproof step 2 and the height h7 of the first fin 31 .

[0035] The utility model sets a boss 21 and makes the height of the boss 21 higher than the height of the waterproof step 2 and the first fin 31. This setting makes it possible that under extreme conditions, when the drainage efficiency of the drain port 5 is insufficient and the liquid level in the liquid storage area 4 reaches the height of the waterproof step 2, the liquid level will be discharged outward from above the first fin 31, further reducing the possibility of liquid entering the interior of the installation shell through the threading hole 6. This setting increases the fault tolerance rate and can effectively protect the internal components even under relatively harsh environmental conditions, thereby ensuring the stable operation and long-term use of the equipment.

[0036] Further, such as Figure 1-4 A mounting shell is shown, wherein the fin 3 also includes a plurality of third fins 33 and fourth fins 34 evenly arranged by the waterproof step 2 toward the first fin 31, the third fins 33 are connected to the first fins 31, at least two of the third fins 33 are located between the two second fins 32, at least two of the fourth fins 34 are located between the two second fins 32 and are spaced apart from the third fins 33 respectively, and the height h2 of the first connecting portion 321 and the height h4 of the third fins 33 are both higher than the height h5 of the fourth fins 34.

[0037] The utility model provides a plurality of third fins 33 and fourth fins 34 on the shell body 1, and the plurality of third fins 33 and fourth fins 34 are distributed circumferentially along the waterproof step 2, two third fins 33 are located between the two second fins 32, one fourth fin 34 is located between the two third fins 33, and a fourth fin 34 is provided between the third fin 33 and the second fin 32, this arrangement greatly increases the heat dissipation area and improves the heat dissipation performance; further, the third fins 33 and the fourth fins 34 have different heights, forming a highly staggered structure, when the shell is normally radiated, this arrangement can guide the air to form a more efficient airflow path between the fins, enhance the convection effect, and thus improve the heat dissipation efficiency; further, the staggered height arrangement of the fins also helps to disperse the water flow, prevent liquid accumulation, and further prevent the liquid from exceeding the waterproof step 2 and entering the threading hole 6, thereby enhancing the waterproof effect; further, the third fins 33 and the fourth fins 34 extend in a straight line, ensuring that the liquid in the liquid storage area 4 can better flow along the third fins 33 and the fourth fins 34 to the drainage area 41.

[0038] Further, such as Figure 1-4 An installation shell is shown, wherein the drain port 5 is provided on the first fin 31 , the drain port 5 is arranged in an arc shape, and the height h5 of the fourth fin 34 is higher than the height h6 of the lowest end of the drain port 5 .

[0039] The utility model sets the height h5 of the fourth fin 34 higher than the height h6 of the lowest end of the drain outlet 5. This setting ensures that when the liquid accumulates to a certain extent in the drainage area 41, it can naturally flow to the drain outlet 5 and be discharged smoothly, further preventing the excessive accumulation of liquid in the liquid storage area 4; further, this setting can improve the drainage efficiency by setting the drain outlet 5 at the lowest notch in the liquid storage area 4; further, the drain outlet 5 is set in an arc shape. This setting speeds up the drainage speed when the liquid water level approaches the radius position due to the large drainage area, preventing the liquid in the liquid storage area 4 from accumulating to a height exceeding the waterproof step 2, further improving the waterproof effect, and when the liquid water level approaches the lowest end of the drain outlet 5, the drainage speed can be slowed down to ensure that the liquid storage area 4 has enough liquid for heat dissipation, further improving the heat dissipation effect.

[0040] Further, such as Figure 1-4 A mounting shell is shown, wherein the second fin 32 is connected to the first fin 31 at one end and is also provided with a second connecting portion 321 connected to the first connecting portion 321, and the shell body 1 is also provided with at least one mounting column 7 extending along the direction of the waterproof step 2, and the mounting column 7 is located at the connection between the first connecting portion 321 and the second connecting portion 322.

[0041] The utility model provides a fixing point for the installation of other components by setting up the mounting column 7, so as to facilitate the installation of the power supply, motor, baffle and other components, thereby enhancing the versatility of the housing; further, the setting of the mounting column 7 also enhances the strength of the second fin 32, making it more stable and reducing the possibility of structural deformation; further, by installing a baffle on the mounting column 7 to shield the waterproof step 2, liquid is better prevented from falling onto the waterproof step 2, further avoiding the risk of liquid entering the threading hole 6.

[0042] Further, such as Figure 1-4 An explosion-proof lamp is shown, which also includes a power supply and / or a fan.

[0043] The utility model realizes the dual functions of power supply and heat dissipation under normal conditions by arranging a power supply, a fan and fins 3. This arrangement ensures that the explosion-proof lamp can continue to operate stably in a high-temperature environment and prevents performance degradation or safety hazards caused by excessive temperature. Furthermore, if liquid heat dissipation is required in some extremely high-temperature environments, the fan can be turned off so that the liquid can fully exert its heat dissipation effect and further improve the heat dissipation efficiency of the explosion-proof lamp. Furthermore, by arranging two threading holes 6, an emergency power supply can be added in addition to the main power supply, and the wires of the main power supply and the emergency power supply are respectively introduced into the interior of the explosion-proof lamp through the two threading holes 6. Combined with the use of sealing rings, the sealing effect of the threading holes 6 is better achieved. This arrangement not only prevents liquid from entering the interior of the explosion-proof lamp through the threading holes 6, but also improves the overall waterproof performance. Furthermore, a power supply and a motor with a waterproof device are used, and they are installed above the waterproof step 2 through a mounting column 7, which can effectively block the threading holes 6 and prevent liquid from falling onto the waterproof step 2, further enhancing the waterproof performance.

[0044] Further, such as Figure 1-4 A mounting housing is shown, wherein the threading hole 6 is also provided with a sealing ring.

[0045] The utility model provides a sealing ring at the threading hole 6, so that after the wire passes through the threading hole 6, liquid is effectively prevented from entering the interior of the lamp through the threading hole 6, and the waterproofness of the shell is further improved.

[0046] Further, such as Figure 1-4 A mounting housing is shown, wherein the waterproof step 2 is arranged in a trapezoidal cross section.

[0047] The utility model sets the cross section of the waterproof step 2 in a trapezoidal shape, so that the liquid falling on the waterproof step 2 can be discharged to the liquid storage area 4 more smoothly through both sides, further reducing the risk of liquid entering the threading hole 6.

[0048] like Figure 1-4 As shown, the implementation method of this embodiment is as follows:

The liquid storage area 4 is also provided with a drainage area 41 for efficient drainage. The fin 3 includes a first fin 31, a second fin 32, a third fin 33 and a fourth fin 34, which are used to increase the heat dissipation effect and the liquid diversion effect. The waterproof step 2 is provided with a boss 21, and the boss 21 is provided with a first threading hole 61 and a second threading hole 62. The height of the boss 21 is higher than the height of the waterproof step 2 and the first fin 31, so as to prevent the liquid level from rising to the position of the threading hole 6. The first fin 31 is provided with a drain port 5, which is arranged in an arc shape. The drain port 5 is located at the lowest position of the liquid storage area 4, which effectively controls the liquid level of the liquid storage area 4 and prevents excessive accumulation of liquid. The second fin 32, the third fin 33 and the fourth fin 34 are distributed along the circumference of the waterproof step 2. The first connection portion 321 of the second fin 32 close to the waterproof step 2 is lower than the waterproof step 2 to prevent excessive accumulation of liquid near the waterproof step 2 and effectively divert the liquid to other liquid storage areas 4. The threading hole 6 is also provided with a sealing ring to prevent the liquid from entering the housing through the threading hole 6. A baffle is installed on the mounting column 7 to prevent body fluids from falling directly onto the waterproof step 2.

[0051] During the installation process, the housing body 1 is first firmly mounted on the lamp.

[0056] Embodiment three:

[0057] The features of the explosion-proof lamp are similar to those of the first embodiment, except that the explosion-proof lamp also includes a main power supply and an emergency power supply with a waterproof device.
