DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 The utility model provides a technical solution: a servo inverter with high temperature alarm protection function, comprising:

[0025] A servo inverter housing 1 having a circuit board 2 installed thereon;

[0026] The pyroelectric infrared sensor 3 is installed at the bottom of the inner wall of the servo inverter housing 1;

[0027] An audible and visual alarm 4 is installed on one side of the outer wall of the servo inverter housing 1; and

[0028] The heat dissipation mechanism 5 is arranged on the servo inverter housing 1. The heat dissipation mechanism 5 includes a heat sink 501 and a dustproof component. The heat sink 501 is installed on the top of the outer wall of the circuit board 2, and the heat sink 501 slides through the top of the outer wall of the servo inverter housing 1. The dustproof component is arranged on the servo inverter housing 1.

[0029] In this embodiment: the pyroelectric infrared sensor 3 installed inside the servo inverter housing 1 can monitor the internal temperature of the servo inverter in real time, and can promptly detect abnormal temperature rise to avoid damage to the servo inverter due to overheating. When the temperature exceeds the safe range, the sound and light alarm 4 will make a sound to remind the staff. The servo inverter housing 1 is heat-dissipated by the heat dissipation mechanism 5 to prevent the internal temperature of the servo inverter from being too high. The heat sink 501 can help the electronic components on the circuit board 2 to dissipate heat to prevent damage to the electronic components due to overheating. The dust-proof component can maintain the heat dissipation performance of the heat sink 501 to prevent dust from accumulating on the heat sink 501 and affecting the heat dissipation effect. The service life of the servo inverter can be extended, and failures and maintenance costs caused by dust can be reduced.

[0030] Specifically, the dustproof components include a protective frame 502, a dustproof net 503, a cleaning component and a movable component. The protective frame 502 is fixedly arranged on the top of the outer wall of the servo inverter housing 1, and the dustproof net 503 slides through one side of the outer wall of the protective frame 502. The cleaning component is arranged on the protective frame 502, and the movable component is arranged on the dustproof net 503.

[0031] In the present embodiment: the protective frame 502 is used to protect the heat sink 501 exposed to the air; the dustproof net 503 can prevent dust from adhering to the heat sink 501 to avoid affecting the heat dissipation effect of the heat sink 501; the cleaning component and the moving component cooperate to process the dust and impurities attached to the dustproof net 503 to avoid dust clogging the dustproof net 503 and affecting the heat dissipation efficiency; the moving component is used to drive the movement of the dustproof net 503.

[0032] Specifically, the cleaning component includes a first brush plate 504 and a second brush plate 505. The first brush plate 504 is fixedly arranged on one side of the outer wall of the protective frame 502, and the second brush plate 505 is fixedly arranged on one side of the outer wall of the protective frame 502. The dustproof net 503 is located between the first brush plate 504 and the second brush plate 505.

[0033] In this embodiment: the first brush plate 504 and the second brush plate 505 are used to clean both sides of the dustproof net 503, so that the dustproof net 503 can be effectively used for a long time, and the maintenance cost is further reduced.

[0034] Specifically, the movable component includes an electric telescopic rod 506 and a movable plate 507. The electric telescopic rod 506 is installed on one side of the outer wall of the protective frame 502. The movable plate 507 is fixedly arranged at the output end of the electric telescopic rod 506, and the movable plate 507 is fixedly arranged at the bottom of the outer wall of the dustproof net 503 near one side edge.

[0035] In this embodiment: the movable plate 507 is driven to move by the electric telescopic rod 506, so that the dustproof net 503 can slide on the protective frame 502, and during the sliding process, the first brush plate 504 and the second brush plate 505 can clean up the impurities and dust attached to the dustproof net 503. Since the first brush plate 504 and the second brush plate 505 are located on one side of the outer wall of the protective frame 502, the protective frame 502 can play a shielding role, so during the cleaning process, impurities and dust will not fall into the servo inverter housing 1.

[0036] Specifically, a mounting frame 6 is fixedly provided on the inner wall of the protection frame 502 .

[0037] In this embodiment: the mounting frame 6 is used to install and place the heat dissipation fan 7.

[0038] Specifically, a plurality of cooling fans 7 are fixedly disposed on the top of the outer wall of the mounting frame 6 .

[0039] In this embodiment: the number of cooling fans 7 can be set according to the actual needs of use. By setting a plurality of cooling fans 7, a corresponding number of cooling fans 7 can be turned on according to the internal temperature of the servo inverter housing 1 to achieve the purpose of rapid heat dissipation and ensure the performance and stability of the servo inverter. The cooling fans 7 can increase air flow and effectively take away heat from the heat sink 501, thereby helping the servo inverter to lower the internal temperature. The power of the cooling fans 7, the electric telescopic rod 506, the sound and light alarm 4 and the pyroelectric infrared sensor 3 comes from an external power supply, which should be electrically connected to the external power supply. The internal circuit principle structure belongs to the common knowledge of technicians in this field and will not be introduced in detail here. The model can be selected according to actual usage.

[0040] During use, the internal temperature of the servo inverter is monitored in real time through the pyroelectric infrared sensor 3. When the temperature exceeds the safe range, the sound and light alarm 4 will sound at the same time, so that the staff can find the abnormal temperature rise in time. The protection device in the servo inverter performs power-off protection processing on the servo inverter to prevent the servo inverter from being damaged due to overheating. The number of cooling fans 7 turned on is increased to increase air flow, and heat is taken away from the heat sink 501 to help the servo inverter reduce the internal temperature. During the heat dissipation process, the dustproof net 503 on the protective frame 502 can prevent dust from adhering to the heat sink 501 to avoid affecting the heat dissipation effect of the heat sink 501. When dust accumulates on the dustproof net 503, the electric telescopic rod 506 can be started to make the movable plate 507 drive the dustproof net 503 to slide on the protective frame 502. During the sliding process, the first brush plate 504 and the second brush plate 505 will clean up the impurities and dust attached to the dustproof net 503.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
