Technical Field

[0001] The utility model belongs to the technical field of electrical box shields, and in particular relates to an electrical box shield with an auxiliary heat dissipation structure. Background Art

[0002] The electrical box is an important electrical component, mainly used to provide power distribution and circuit protection, and to control the switching, protection and monitoring of motors and other electrical equipment. In real life, electrical boxes are easily damaged due to long-term exposure to the outside world, so they need to be protected by electrical box covers.

[0003] However, after long-term use, the internal and surrounding temperatures of the existing electrical box shields are prone to being too high, and most electrical box shields are always in a semi-enclosed space, which makes heat dissipation inconvenient, thereby affecting the service life of the internal structure of the device and causing internal circuits to burn out. An electrical box shield with an auxiliary heat dissipation structure is now provided to alleviate the problem of poor heat dissipation effect of the electrical box shield. Summary of the invention

[0004] The utility model realizes the purpose of rapid heat dissipation of the electrical box shield by cooperating with the heat dissipation mechanism, the heat absorbing plate and the heat sink so that the heat can be discharged from the dustproof net through the fan and transferred through the heat absorbing plate and discharged by the heat sink.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A shield for an electrical box with an auxiliary heat dissipation structure comprises a shield body, a bracket fixedly mounted on the bottom surface of the shield body, a heat dissipation mechanism arranged on the inner top surface of the shield body, a cleaning assembly fixedly mounted on the shield body, a heat absorbing plate arranged on the inner side wall and the inner bottom of the shield body, a heat sink fixedly mounted on the bottom end of the heat absorbing plate located at the inner bottom of the shield body, and the heat sink passes through the bottom of the shield body and extends into the bracket.

[0008] Preferably, the cleaning component includes a dustproof box, the dustproof box is arranged on the upper surface of the shield body, a motor is arranged on the back side of the inner cavity of the dustproof box, a turntable is arranged at the output end of the motor, a rotating rod is arranged on the surface of the turntable away from the motor, a fixed seat is arranged on one side of the rotating rod, a cylinder is arranged on one side of the fixed seat, a movable frame is arranged outside the cylinder, a cleaning brush is arranged at one end of the movable frame, and a dustproof net is installed on the dustproof box.

[0009] Preferably, a plurality of mounting grooves are provided in the shield body, and the heat absorbing plate is clamped in the mounting grooves.

[0010] Preferably, a plurality of heat sinks are equidistantly arranged along the heat absorbing plate; a thermal conductive coating is arranged above the heat absorbing plate; and the bracket structure is hollow.

[0011] Preferably, a "U"-shaped limiting strip is provided above the dustproof box, and a limiting groove is provided on the bottom surface of the dustproof net.

[0012] Compared with the prior art, the gain effect of the utility model is:

[0013] 1. By setting up a heat dissipation mechanism, under the action of the fan suction, the heat generated in the shield body enters the air inlet pipe through the suction head, passes through the fan and the air outlet pipe in turn, and is finally transported to the dustproof box, and then the hot air is discharged through the dustproof net, which can achieve rapid heat dissipation and ensure the normal use of internal electrical components.

[0014] 2. By setting up a heat absorbing plate and a heat sink, a large amount of heat generated in the shield body can be transferred through the heat absorbing plate, and the heat transferred by the heat absorbing plate can be quickly discharged with the use of the heat sink. The thermal conductive coating can speed up the heat discharge speed, so that the shield body can be used normally.

[0015] 3. By setting up a cleaning component, the turntable is driven by the motor to rotate, and then the rotating rod is driven to rotate. Under the action of the fixed seat and the cylinder, the rotating rod drives the movable frame to swing back and forth, so that the movable frame drives the cleaning brush to swing back and forth.

[0032] Those skilled in the art will appreciate that, because existing electrical box shields are not good at dissipating heat, after long-term use, the internal and surrounding temperatures are too high, affecting the service life of the internal structure of the device and causing internal circuits to burn out.

[0033] In this embodiment, the fan 32 is first turned on. Under the suction force of the fan 32, the heat generated in the protective cover body 1 enters the air inlet pipe 33 through the suction head 34, and then passes through the fan 32 and the air outlet pipe 35 in turn, and is finally transported to the cleaning component 4, and then the hot air is discharged.

[0034] See also Figure 1-5The cleaning component 4 includes a dustproof box 41, one end of the air outlet pipe 35 extending out of the protective cover body 1 is connected to the dustproof box 41, a motor 42 is arranged on the back of the inner cavity of the dustproof box 41, a turntable 43 is fixedly arranged on the output end of the motor 42, a rotating rod 44 is arranged on the surface of the turntable 43 away from the motor 42, a fixed seat 45 is arranged on one side of the rotating rod 44, the fixed seat 45 is fixedly connected to the inner bottom surface of the dustproof box 41, a cylinder 46 is arranged on one side of the fixed seat 45, a movable frame 47 is arranged outside the cylinder 46, and the inner cavity of the movable frame 47 is slidably matched with the surface of the rotating rod 44, a cleaning brush 48 is fixedly arranged on the other end of the movable frame 47, and a dustproof net 49 is installed above the dustproof box 41.

The limiting strip 411 can be engaged with the limiting groove 491 , so that the dustproof net 49 can be quickly removed from the dustproof box 41 .

[0036] In actual application, since the surface of the existing dustproof net 49 is easy to adhere to dust during use, if the dust is adhered to the surface for a long time without cleaning, the heat dissipation effect of the heat dissipation mechanism 3 will be reduced.

[0037] In this embodiment, the motor 42 is first started to operate, and the output end of the motor 42 drives the turntable 43 to rotate, and the turntable 43 drives the rotating rod 44 to rotate. Under the action of the fixed seat 45 and the cylinder 46, the rotating rod 44 drives the movable frame 47 to swing back and forth, and the movable frame 47 drives the cleaning brush 48 to swing back and forth. When the cleaning brush 48 swings upward, it vibrates the dustproof net 49 to clean the dustproof net 49.

[0038] Working principle: When the inside of the electrical box shield is overheated, the fan 32 is turned on first. Under the suction of the fan 32, the heat generated in the shield body 1 enters the air inlet 33 through the air suction head 34, and then passes through the fan 32 and the air outlet 35 in sequence, and is finally transported to the dust box 41, and the heat is discharged through the dust net 49; at the same time, the heat generated in the shield body 1 is transferred through the heat absorbing plate 5, and then the heat transferred by the heat absorbing plate 5 is quickly discharged with the use of the heat sink 6, and the thermal conductive coating can accelerate the heat discharge. The output speed makes the shield body 1 able to be used normally; when it is necessary to clean the surface of the dustproof net 49, first start the motor 42, the output end of the motor 42 drives the turntable 43 to rotate, the turntable 43 drives the rotating rod 44 to rotate, under the action of the fixed seat 45 and the cylinder 46, the rotating rod 44 drives the movable frame 47 to swing back and forth, so that the movable frame 47 drives the cleaning brush 48 to swing back and forth, and the cleaning brush 48 vibrates the dustproof net 49 when it swings upward, so as to clean the dustproof net 49 and ensure the normal discharge of heat.
