[0030] This embodiment provides a cleaning device for power engineering equipment, see reference. Figures 1-4As shown, including the gas tank 1 and the gas tank 2, the bottom of the gas tank 1 is provided with a cavity 11, the top opening of the gas tank 1 is installed with a fan 12, the fan 12 is covered with a flow cover 121, the top of the flow cover 121 is connected with an air outlet pump 122, the air outlet pump 122 is communicated with one end of the air jet pipe 3 through the air outlet pipe 13, the upper end of the sidewall of the gas tank 1 is provided with an air inlet 14, the top of the gas tank 2 is connected with a fan 21, the air inlet 14 of the fan 21 is connected with one end of the air suction pipe 4 through the air return pipe 22, the other end of the air suction pipe 4 is installed with an air suction cover 41, the bottom end of the sidewall of the gas tank 2 is provided with an air outlet 23, the connecting part of the air jet pipe 3, the air suction pipe 4 and the air outlet pipe 13, the air return pipe 22 is fixedly provided with a connecting block 5.

[0031] In the above embodiment, the bottom of the gas tank 1 is provided with a cavity 11, the cavity 11 is used to place dry ice, the top opening of the gas tank 1 is installed with a fan 12, and the upper end of the sidewall of the gas tank 1 is provided with an air inlet 14, the fan 12 runs to mix the carbon dioxide generated by the gasification of dry ice with the air entering the air inlet 14 and blows into the flow cover 121, the mixed gas of carbon dioxide and air is pressurized by the air outlet pump 122 and then injected into the air jet pipe 3 through the air outlet pipe 13, and the mixed gas is sprayed out of the air outlet of the air jet pipe 3. The top of the gas tank 2 is connected with a fan 21, the fan 21 is used to suck the gas in the air return pipe 22 into the gas tank 2, so that a negative pressure is generated in the air return pipe 22, thereby sucking the air in the air suction pipe 4 into the gas tank 2, thereby making the air inlet of the air suction pipe 4 produce a suction effect, which can realize the air in the air suction cover 41 into the gas tank 2 and then discharged through the air outlet 23 of the gas tank 2. The connecting part of the air jet pipe 3, the air suction pipe 4 and the air outlet pipe 13, the air return pipe 22 is fixedly provided with a connecting block 5, and the operator can control the orientation of the air jet pipe 3 by holding the connecting block 5. In summary, the mixed gas of carbon dioxide and air is pressurized by the air outlet pump 122 and injected into the air jet pipe 3, and sprayed out of the air outlet of the air jet pipe 3, the operator holds the connecting block 5 to control the orientation of the air jet pipe 3 towards the shell of the electrical equipment, the sprayed gas impacts the deposited dust, making the deposited dust blow away from the shell of the electrical equipment, and the shell of the electrical equipment is washed by the gas, so that the components of the cleaning device do not directly touch the electrical equipment during the cleaning process. Compared with liquid cleaning, the risk of short circuit caused by leakage of cleaning liquid into the electrical equipment can be avoided, which is beneficial to improve the safety of the cleaning process of the electrical equipment. Further, by mixing carbon dioxide and air, the oxygen content in the air during air cleaning can be reduced, the oxidation reaction of metal parts in the electrical equipment with oxygen in the air can be avoided, the carbon dioxide does not support combustion, and the risk of fire during cleaning can be prevented, which is beneficial to improve the safety of the cleaning work. In addition, the opening of the air suction cover 41 is directed towards the air jet pipe 3, which can suck the dust blown by the air jet pipe 3 into the gas tank 2 through the air suction pipe 4 and then discharge it from the air outlet 23, therebyFigure 2 For example, the air suction cover 41 is arranged above the air outlet of the air jet pipe 3, and when cleaning, the air outlet of the air jet pipe 3 is aimed at the dust adhered to the shell of the electrical equipment, and the ejected gas of the air jet pipe 3 first contacts the dust to blow the dust away, and the blown-off part of the dust is sucked into the air suction cover 41 above the air jet pipe 3, so that the blown-off dust is prevented from falling back to the surface of the electrical equipment, and the cleaning efficiency is improved. In addition, in actual use, the air suction flow rate of the air suction cover 41 can be adjusted to be smaller than the air jet flow rate of the air jet pipe 3, so as to avoid that the air suction rate of the air suction cover 41 is too large to deviate the ejected gas of the air jet pipe 3, and further affect the blowing effect of the ejected gas of the air jet pipe 3 on the dust.

[0032] In an embodiment of the present application, referring to Figure 4 As shown in the figure, the side wall of the air outlet box 1 is provided with a socket 15, and the socket 15 is inserted with a plug 151.

[0033] In the above embodiment, dry ice can be put into the plug 151, and then the plug 151 is inserted into the placement cavity 11 through the socket 15. By inserting and pulling the plug 151 at the socket 15, the dry ice in the placement cavity 11 can be supplemented, and the adding efficiency of the dry ice is improved, which is beneficial to improve the working efficiency of the cleaning device.

[0034] In an embodiment of the present application, referring to Figure 4 As shown in the figure, the side wall of the air outlet box 1 and the outer side wall of the plug 151 are connected with a magnetic buckle 6.

[0035] In the above embodiment, the magnetic buckle 6 connected to the side wall of the air outlet box 1 and the outer side wall of the plug 151 plays a role in adsorbing and fixing the plug 151, preventing the plug 151 from slipping out of the air outlet box 1 during the transportation and tilting of the air outlet box 1. On the other hand, the magnetic buckle 6 is arranged on the outer side wall of the plug 151, which increases the gripping points on the outer side of the plug 151, facilitating the insertion and pulling of the plug 151, and is beneficial to improve the convenience of using the cleaning device.

[0036] In an embodiment of the present application, referring to Figure 3 As shown in the figure, the air inlet 14 of the air outlet box 1 is provided with a filter screen 141.

[0037] In the above embodiment, the filter screen 141 arranged at the air inlet 14 is used to protect the air inlet 14 from foreign matters falling into the air outlet box 1 during the transportation of the air outlet box 1. On the other hand, when the cleaning device is running, the air inlet 14 is in a state of air suction, and the filter screen 141 plays a role in filtering to prevent foreign matters from being sucked into the air outlet box 1 and causing the blockage of the air pipe, which is beneficial to improve the stability of the cleaning device during running.

[0038] In an embodiment of the present application, referring to Figure 4As shown, a filter bag 24 is installed inside the gas collection box 2.

[0039] In the above embodiment, some of the blown dust is drawn into the air collection box 2 through the suction pipe 4. If it is discharged directly, it will pollute the air and the dust will also damage the respiratory system of the staff. The gas entering the air collection box 2 can be filtered by the filter bag 24 and then discharged from the air outlet 23. The dust and impurities are retained in the filter bag 24, which can prevent the dust from polluting the air after it is discharged and protect the health of the staff.

[0040] In one embodiment of this application, see reference Figure 1 , Figure 2 As shown, a handle 51 is installed on the upper end of the connecting block 5.

[0041] In the above embodiment, the handle 51 adds a gripping point for the connecting block 5, making it easier for operators to control the movement of the connecting block 5, thereby making the orientation of the air jet pipe 3 more flexible and improving the working efficiency of the cleaning device. Optionally, the handle 51 is made of insulating material.

[0042] In one embodiment of this application, see reference Figure 1 As shown, the side walls of the air outlet box 1 and the air collection box 2 are connected by a fixing rod 7.

[0043] In the above embodiment, the side walls of the air outlet box 1 and the air collection box 2 are connected by a fixing rod 7, which can improve the integrity between the air collection box 2 and the air outlet box 1. By holding the fixing rod 7, the air outlet box 1 and the air collection box 2 can be moved at the same time, which is beneficial to improving the convenience of moving the cleaning device.

[0044] In actual use, before cleaning electrical equipment, workers should wear insulated clothing. Fan 12 mixes the carbon dioxide produced by the vaporization of dry ice with the air entering through inlet 14 and blows it into the jet pipe 3. Operators can control the jet pipe 3's orientation towards the electrical equipment's casing by holding the connecting block 5. The ejected gas impacts the deposited dust, causing it to be blown away from the equipment's casing. The suction hood 41's opening faces the jet pipe 3, allowing some of the dust blown away by the jet pipe 3 to be sucked into the air collection box 2 through the suction pipe 4 and then discharged from the outlet 23, preventing the blown-away dust from falling back onto the electrical equipment surface. Furthermore, the jet pipe 3 and suction pipe 4 are made of ceramic material, and the connecting block 5 is made of insulating rubber, providing insulation to prevent the suction pipe 4 and jet pipe 3 from contacting the electrical equipment and causing electric shock. The outlet pipe 13 and return pipe 22 can be made of polyethylene hose, with the connection length adjusted according to actual operating conditions.
