[0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. A lot of heat is generated during the operation of electrical equipment, which cannot be completely discharged through the ventilation holes. At this time, a radiator is needed to help dissipate heat. When using a radiator, it is necessary to install the radiator at the ventilation hole to discharge the heat through wind. However, when the existing radiator is in operation, the shutter can only block part of the dust, and some dust will enter the radiator and electrical equipment, affecting the normal operation of the radiator and electrical equipment.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0016] Example: See Figure 1-6 , a heat dissipation device for safe operation of electrical equipment, comprising a casing 1, characterized in that: a storage compartment 2 is arranged on the inner surface of the casing 1, a fan 12 is fixed on the inner surface of the casing 1 and arranged in the storage compartment 2, a dustproof net 24 is arranged in the storage compartment 2 through an installation component, a base 11 is fixedly installed on the back of the storage compartment 2, an electrical equipment housing 13 is installed on the back of the base 11 through a connecting mechanism, and a shutter 14 is arranged on the surface of the electrical equipment housing 13;

[0017] The installation assembly is composed of a connecting rod 21, a plug plate 22, a plug rod 23 and a slot 25; a group of L-shaped connecting rods 21 are relatively fixed on the left and right sides of the storage bin 2, and the plug plate 22 is inserted in the middle of a group of connecting rods 21. Under the action of the connecting rods 21, the plug plate 22 is supported and limited, and the side opening of the storage bin 2 is sealed by the plug plate 22.

[0018] T-shaped rods 23 are fixed on the upper and lower sides of the inner surface of the storage bin 2, and T-shaped slots 25 are provided on the upper and lower sides of the dustproof net 24. The dustproof net 24 is installed in the storage bin 2 by inserting the rods 23 into the slots 25, which facilitates the disassembly and assembly of the dustproof net 24.

[0019] The connection mechanism is specifically as follows: L-shaped limit rods 3 are provided on both sides of the electrical equipment housing 13, and the bottom ends of the two limit rods 3 are fixedly connected by a cross plate 31; under the connection between the limit rods 3 and the cross plate 31, the base 11 is snap-fitted and installed so that the base 11 fits against the surface of the electrical equipment housing 13.

[0020] Two installation chambers 32 are symmetrically arranged on the upper part of the base 11. Support springs 34 and limit plates 35 are arranged inside the installation chambers 32. One end of the support spring 34 is fixed to the installation chamber 32, and the other end is fixed to the limit plate 35. A snap-fit ​​block 36 is arranged outside the limit plate 35. A through hole 33 is provided on the surface of the installation chamber 32. A snap-fit ​​hole 37 matching the through hole 33 is provided on the upper part of the electrical equipment housing 13. The snap-fit ​​block 36 is snap-fitted to the surface of the snap-fit ​​hole 37, so that the base 11 is connected to the electrical equipment housing 13 through the installation chamber 32. Under the support of the support spring 34, the limit plate 35 is abutted against the inner surface of the installation chamber 32, and then the snap-fit ​​block 36 is snap-fitted to the snap-fit ​​hole 37, so as to realize the installation and fixation of the base 11.

[0021] Working principle: When the heat dissipation device is in normal use, the motor installed in the fan 12 drives it to rotate, and the heat of the electrical equipment is discharged outside the equipment through the shutter 14 to achieve the effect of heat dissipation; dust prevention is achieved by splitting the radiator casing 1 and the base 11 and installing the storage compartment 2 between the two.

[0022] When placing the dustproof net 24, first remove the plug plate 22 from the surface of the connecting rod 21, insert the slots 25 on both sides of the dustproof net 24 into the surface of the installation compartment 32, and push the dustproof net 24 into the storage compartment 2, so that the dustproof net 24 is placed between the fan 12 and the electrical equipment housing 13, and finally insert the plug plate 22 back to the connecting rod 21, so that the dustproof net 24 can prevent dust from entering. When the dustproof net 24 needs to be cleaned and replaced, just pull out the plug plate 22 again to take out the dustproof net 24.

[0023] When installing the heat dissipation device on the electrical equipment, the base 11 needs to be pressed against the surface of the electrical equipment housing 13, the locking block 36 is squeezed and moves into the installation bin 32, the limit plate 35 slides along the inner surface of the installation bin 32, and the support spring 34 is in a compressed state. The base 11 is placed between the two sets of limit rods 3 and slides downward to engage with the limit rods 3. When the base 11 is pressed against the cross plate 31, the supporting force applied by the support spring 34 on the limit plate 35 can press it against the inner surface of the installation bin 32, and engage the locking block 36 and the locking hole 37, thereby completing the installation of the heat dissipation device.
