[0045] Embodiment 1:

[0046] like Figure 1 to Figure 5 As shown, the present invention is an ultrasonic cleaning device for a secondary terminal block of a substation, comprising a cleaning hood 1, an ultrasonic component 2, an air blast component 3 and a dust collection component 4, wherein the cleaning hood 1 covers the secondary terminal block; in this embodiment, the setting of the cleaning hood 1 can form a relatively independent cleaning space around the secondary terminal block, so as to avoid the situation in which dust is blown onto other electrical equipment during the cleaning process and causes circuit failure; the ultrasonic component 2 is used to form an ultrasonic vibration environment in the cleaning hood 1; the setting of the ultrasonic component 2 can utilize the rapid vibration effect of ultrasonic waves to effectively peel off the dust attached to the secondary terminals, and then blow air into the secondary terminal block through the air blast component 3, thereby effectively bringing out the dust inside the secondary terminals, and finally utilize the dust collection component 4 to discharge the dust in the cleaning hood 1 to the outside, thereby achieving deep cleaning of the secondary terminal block.

[0047] Specifically, the ultrasonic component 2 includes an ultrasonic vibrator 21, a connecting line 22 and an ultrasonic generator 23. The ultrasonic vibrator 21 is arranged inside the cleaning cover 1, and the ultrasonic generator 23 is arranged outside the cleaning cover 1. One end of the connecting line 22 is electrically connected to the ultrasonic vibrator 21, and the other end of the connecting line 22 passes through the cleaning cover 1 and is electrically connected to the ultrasonic generator 23. During use, the ultrasonic generator 23 sends a working signal and transmits it to the ultrasonic vibrator 21 through the connecting line 22. The ultrasonic vibrator 21 starts to work after receiving the working signal, thereby generating ultrasonic vibration, so that the dust and other dirt attached to the surface of the secondary terminal 5 are cleaned off by using this vibration effect, thereby effectively solving the problem that the dirt attached to the secondary terminal is difficult to remove. Furthermore, the ultrasonic vibrator 21 is inserted into the inner cavity of the secondary terminal 5. At this time, the ultrasonic vibrator 21 can generate a strong vibration effect in the inner cavity of the secondary terminal 5, thereby effectively peeling off the dirt in the difficult-to-clean positions such as the internal gaps of the secondary terminal 5. Specifically, the ultrasonic vibrator 21 is inserted into the inner cavity of the secondary terminal 5 from the vertical channel in the center of the secondary terminal 5. In order to facilitate the electrical connection between the ultrasonic vibrator 21 and the ultrasonic generator 23, an air socket is provided on the cleaning cover 1, and the connecting wire 22 is divided into two sections. One section of the connecting wire 22 is provided in the cleaning cover 1, and one end thereof is electrically connected to the ultrasonic vibrator 21, and the other end is electrically connected to the air socket. The other section of the connecting wire is provided outside the cleaning cover 1, one end is electrically connected to the ultrasonic generator 23, and the other end is provided with an air socket and the air socket is inserted into the air socket, so that the electrical connection between the ultrasonic vibrator 21 and the ultrasonic generator 23 can be conveniently and effectively achieved, and then the ultrasonic vibrator 21 can be effectively controlled to clean the inner cavity of the secondary terminal 5 and remove the dirt attached to the secondary terminal 5. At the same time, after the work is completed, the disassembly can be completed quickly, and the ultrasonic generator 23 can be quickly separated, which is convenient for the storage and transportation of the device.

[0048] A plurality of ultrasonic vibrators 21 are arranged in the cleaning cover 1, and the plurality of ultrasonic vibrators 21 are arranged evenly and equidistantly in the cleaning cover 1; in this embodiment, the plurality of ultrasonic vibrators 21 are arranged to realize the cleaning work of a plurality of secondary terminals 5 at the same time, and further, the distance between two adjacent ultrasonic vibrators 21 is the same as the distance between two adjacent secondary terminals 5, so that each secondary terminal 5 is correspondingly configured with an ultrasonic vibrator 21 to realize the cleaning work, thereby effectively improving the cleaning efficiency of the device for the secondary terminal row.

[0049] In this embodiment, the following specific structure of the air blowing assembly 3 is provided, which can be equivalent to the structure that can achieve the corresponding effect to replace the air blowing assembly 3 structure provided in this embodiment. The air blowing assembly 3 includes an air blowing pipe 31, a connecting pipe 32 and a blower 33. The air blowing pipe 31 is arranged inside the cleaning cover 1 and blows air into the inner cavity of the secondary terminal 5; the blower 33 is arranged outside the cleaning cover 1, one end of the connecting pipe 32 is connected to the air blowing pipe 31, and the other end of the connecting pipe 32 passes through the cleaning cover 1 and is connected to the blower 33. Blowing air into the inner cavity of the secondary terminal 5 through the air blowing pipe 31 can effectively remove the dirt in the inner cavity, thereby completing the cleaning work of the inner cavity of the secondary terminal 5. In order to further improve the effect of the blast tube 31 in removing dirt from the inner cavity of the secondary terminal 5, the ultrasonic vibrator 21 includes an ultrasonic vibrator 211 and a central sleeve 212, wherein the ultrasonic vibrator 211 is arranged on the outer surface of the central sleeve 212; the central sleeve 212 is inserted into the inner cavity of the secondary terminal 5, and the blast tube 31 is inserted into the central sleeve 212. In this structure, not only can the blast tube 31 be effectively sent into the inner cavity of the secondary terminal 5, but also the structural coordination with the ultrasonic vibrator 21 can effectively reduce the structural size, thereby more conveniently inserting the blast tube 31 into the inner cavity of the secondary terminal 5, and effectively improving its cleaning effect on dirt in the inner cavity of the secondary terminal 5. Specifically, in order to improve the ability of the blast pipe 31 to remove dirt from the inner cavity of the secondary terminal 5, an air outlet 213 is provided on the central sleeve 212, and the installation position of the ultrasonic vibrator 211 avoids the air outlet 213; an air outlet 311 is provided on the side wall of the blast pipe 31, and the setting position of the air outlet 311 is adapted to the opening position of the air outlet 213. And the connecting wire 22 is routed along the surface of the connecting pipe 32 and fixed to the connecting pipe 32.

[0050] In this embodiment, in order to achieve the connection effect of the connecting pipe 32, the following specific connecting pipe 32 structure and its connection with the blower 33 and the blast pipe 31 are provided. The connecting pipe 32 includes a diverter section 321 and an external section 322, one end of the external section 322 is connected to the blower 33, and the other end of the external section 322 is connected to the air inlet of the diverter section 321; the diverter section 321 is provided with a plurality of air outlets, and each of the air outlets is connected to a blast pipe 31. The diverter section 321 is horizontally arranged in the cleaning cover 1, and the diverter section 321 is arranged at the central position of the cleaning cover 1 along the length direction of the cleaning cover 1, so that the blast pipe 31 vertically connected thereto can be accurately and effectively inserted into the cavity structure in the middle of the secondary terminal 5, so that the blower 33 is used to transport airflow to the blast pipe 31, so as to use the airflow to take away the dirt in the inner cavity of the secondary terminal 5, and effectively realize the cleaning work of the inner cavity of the secondary terminal 5. At the same time, in order to facilitate the connection with the blower 33, in this embodiment, after the external section 322 passes through the cleaning cover 1, a pipeline structure is formed outside the cleaning cover 1, so that the air supply pipe of the blower 33 can be conveniently and effectively connected. At the same time, after the work is completed, it can be quickly disassembled and quickly separated from the blower 33, which is convenient for the storage and transportation of the device.

[0051] A dust suction port 11 is provided at the center of the top of the cleaning cover 1, and the dust suction port 11 is connected to the dust suction assembly 4; in this embodiment, the cleaning cover 1 is preferably a conical structure with a large bottom and a small top, so that dust can be concentrated to the central dust suction port 11 at the top of the cleaning cover 1, and then the dust can be quickly discharged from the cleaning cover 1 through the external dust suction assembly 4 (vacuum cleaner); a wire notch 12 is provided at the bottom of the cleaning cover 1 for the connecting wire on the secondary terminal 5 to pass through. In this embodiment, the provision of the wire notch 12 can facilitate the installation of the cleaning cover 1 when the wire is connected, ensure that the cleaning cover 1 can effectively cover the secondary terminal row, and prevent dust from being blown onto other electrical equipment during the cleaning process.
