[0036] The intelligent protection controller is equipped with a dustproof ventilation control system, which includes a dustproof ventilation processing unit. The input end of the dustproof ventilation processing unit is connected to a blockage sensing unit, a ventilation parameter acquisition unit and a remote dustproof data receiving unit, and the output end of the dustproof ventilation processing unit is connected to a backflush control unit and a remote signal transmission unit.

[0037] The input end of the blockage sensing unit is connected to the dust isolation ventilation sensing component 4, the input end of the ventilation parameter acquisition unit is respectively connected to the temperature and humidity collector and the ventilation fan signal arranged in the protective device body 1, and the output end of the back-blowing control unit is connected to the ventilation fan signal arranged in the protective device body 1;

[0039] The output end of the personalized dust control unit is connected to the remote dust data receiving unit signal through the remote signal transmitter, and the output end of the dust maintenance display unit is connected to the display signal set on the power maintenance platform. Through the cooperation of the dust removal sheet 2, the dust isolation ventilation sensing component 4 and the dust ventilation control system, some fine dust and impurities can be effectively blocked, and the blockage of the dust protection position can be avoided by backblowing. While ensuring the effective heat dissipation effect of the ventilation and air exchange of the protective device body 1, the pollution of the internal power metering equipment by dust and impurities is greatly reduced, and the normal operation of the power metering equipment is ensured. In addition, through the cooperation of the power metering maintenance platform and the road section data analysis and processing unit, the environmental applicability of the dust ventilation measures of the protective device body 1 can be effectively regulated according to the setting position of the protective device body 1 and the dust ventilation data of the dust ventilation processing unit.

[0040] Figure 3 - Figure 7 , Fig. 9 and Fig.10 The dust-proof ventilation sensing assembly 4 is shown to include a dust-proof base plate 42 fixedly mounted on the rear end of the ventilation lining 11, and sensing columns 43 are fixedly connected to the four corners of the front end of the dust-proof base plate 42. The front end of the sensing column 43 extends to the outside of the ventilation lining 11 and is provided with an elastic guide sleeve 44 fixedly connected to the ventilation lining 11. The inner wall of the elastic guide sleeve 44 on the side away from the sensing column 43 is fixedly connected with a trigger column 45 that cooperates with the sensing column 43. The input end of the blockage sensing unit is connected to the signal of the sensing column 43. The cooperation of the sensing column 43, the blockage sensing unit and the trigger column 45 can effectively realize the dust-proof ventilation control system to collect data on the dustproof state and setting environment of the protective device body 1. On the one hand, it can detect the blockage of the dust removal sheet 2 on the protective device body 1. When poor ventilation occurs, the blockage can be dealt with in time. While ensuring the effectiveness of dust prevention measures, the ventilation effect of the protective device body 1 is effectively guaranteed, and the heat dissipation of the protective device body 1 is promoted to ensure the normal operation of the internal power metering equipment. On the other hand, through the transmission of blockage data, the auxiliary section data analysis and processing unit can judge and analyze the environment of the section where the protective device body 1 is set, and then according to the analyzed environmental data, the backblowing effect of the protective device body 1 is personalized. Adjust and set, while effectively ensuring the dust prevention effect of the protective device body 1, reduce the probability of subsequent blockage of the protective device body 1, so as to ensure the continuity of the ventilation effect of the protective device body 1 and promote its protective effect on the power metering equipment.

[0041] Figure 4 - Figure 7 It is shown that an elastic clamping sleeve 3 is fixedly connected to the dust-proof bottom plate 42, and the front end of the elastic clamping sleeve 3 extends to the front side of the ventilation lining 11 and is located on the rear side of the dust-proof outer cover 12. The outer end of the elastic clamping sleeve 3 is fixedly connected to a ventilation baffle 41, and the ventilation baffle 41 is fixedly connected to the elastic guide sleeve 44. The cooperation of the ventilation baffle 41 and the elastic clamping sleeve 3 can effectively visualize the blockage state of the dust removal sheet 2, effectively assist the dust-proof ventilation control system to collect the dust-proof ventilation data of the protective device body 1, and can also monitor the state of the dust removal sheet 2 in real time. While improving the intelligence of the dust-proof measures of the protective device body 1, it can also effectively ensure the continuous effectiveness of the dust-proof ventilation measures of the protective device body 1, and avoid abnormal ventilation of the protective device body 1 due to the blockage of the dust removal sheet 2.

[0042] Figure 6 It is shown that a reset elastic member 46 sleeved on the outside of the trigger column 45 is fixedly connected to the inner wall of the elastic guide sleeve 44 away from the sensing column 43, and the rear end of the reset elastic member 46 abuts against the sensing column 43, and the reset elastic member 46 is made of insulating material. The cooperation between the reset elastic member 46 and the elastic guide sleeve 44 can effectively promote the reset effect of the elastic clamping sleeve 3 and the ventilation baffle 41, on the one hand, ensuring the effectiveness and timeliness of the triggering of the sensing column 43, on the other hand, in the process of blockage of the dust removal sheet 2, it can cooperate with the backblowing effect of the ventilation fan to increase the mobility of the dust removal sheet 2 in the dust removal process, thereby improving the action and effectiveness of regulating the blockage of the dust removal sheet 2.

[0043] Figure 1 - Figure 7 , Fig. 9 and Fig.10 It is shown that both the left and right ends of the dust removal sheet 2 and the baffle sheet 21 are embedded with electric heating wires, and the left and right electric heating wires at corresponding positions are connected with a heat-conducting strip embedded in the dust removal sheet 2 and the baffle sheet 21. The output end of the dust-proof ventilation processing unit is also connected to a drying dust-proof unit, and the output end of the drying dust-proof unit is connected to the electric heating wire signal. The cooperation of the drying dust-proof unit and the electric heating wire can effectively realize the drying effect on the dust removal sheet 2 and the baffle sheet 21, and when the humidity outside the protective device body 1 is too high, the dust removal sheet 2 and the baffle sheet 21 are prevented from being increased in humidity and causing dust The adhesion effect effectively ensures the effectiveness of the dust-proof ventilation of the dust removal sheet 2 and the partition sheet 21, and when the dust removal sheet 2 is blocked, the drying effect and the backblowing of the ventilation fan can promote the clearing of the blockage of the dust removal sheet 2, effectively extend the service life of the dust removal sheet 2, and reduce the protection cost of the protective device body 1. By promoting the intelligence of the dust-proof ventilation function of the protective device body 1, the maintenance difficulty of the protective device body 1 and the labor cost during the maintenance process are reduced, and the economic benefits of the protective device body 1 during the application process are effectively promoted.

[0044] Figure 1- Figure 7 , Fig. 9 and Fig.10 It is shown that during the application of the protective device body 1, air will enter the protective device body 1 through the shielding, dust removal and filtration of the dustproof cover 12, the dust removal sheet 2 and the baffle sheet 21 under the action of the ventilation fan, thereby realizing the heat exchange effect in the protective device body 1. In addition, through the action of the dust removal sheet 2 and the baffle sheet 21, some fine dust and impurities can be blocked to prevent them from entering the protective device body 1 and causing pollution to the power metering equipment, thereby ensuring the normal operation of the power metering equipment.

[0045] During the dust removal and filtration process of the dust removal sheet 2, the section data analysis and processing unit in the power metering maintenance platform first transmits the initial backblowing parameter setting to the remote dust prevention data receiving unit through the personalized dust prevention control unit, so that the remote dust prevention data receiving unit transmits the initial backblowing parameters to the dust prevention ventilation processing unit, and then the dust prevention ventilation processing unit issues a control instruction to the backblowing control unit according to the parameter setting, so that the backblowing control unit issues a control instruction to the ventilation fan according to the set cycle, and controls the reversal of the ventilation fan according to the backblowing cycle, thereby generating a reverse blowing effect to the partition sheet 21, the dust removal sheet 2 and the dustproof cover 12, thereby effectively removing dust and impurities adhering to the partition sheet 21, the dust removal sheet 2 and the dustproof cover 12, reducing the probability of their blockage, ensuring the dustproof and ventilation effect of the protective device body 1, and promoting the protective effect of the protective device body 1.

[0046] In the process of the protective device body 1 protecting its internal power metering equipment, the ventilation fan maintains continuous ventilation when it is not controlled by the back-blowing control unit, and the temperature and humidity collector inside the protective device body 1 collects temperature and humidity data in real time, and then the ventilation data collection unit collects the temperature and humidity data and the operation data of the ventilation fan respectively, and transmits the parameters to the dust-proof ventilation processing unit, so that the dust-proof ventilation processing unit can judge the back-blowing control effect and the dust-proof effect of the dust removal sheet 2, the baffle sheet 21 and the elastic clamping sleeve 3 according to the changes in the temperature and humidity data in the ventilation fan and the protective device body 1, and can send actual data feedback to the section data analysis processing unit in time through the remote signal transmission unit;

[0047] In addition, the dust-proof ventilation processing unit can also judge the humidity data of the external environment of the protective device body 1 at this time according to the temperature and humidity data transmitted by the ventilation parameter acquisition unit. When the humidity data is large, a drying instruction is issued to the drying dust-proof unit, so that the drying dust-proof unit controls the electric heating wire to energize, and electrically heats the dust removal sheet 2 and the baffle sheet 21 to evaporate the humidity on the upper end, thereby preventing dust and impurities from sticking to the dust removal sheet 2 and the baffle sheet 21, thereby effectively ensuring the effectiveness and continuity of the dust-proof ventilation of the protective device body 1, further promoting the applicability of the dust-proof effect to different environments, and improving the intelligence and automation of the dust-proof effect of the protective device body 1.

[0048] Then, during the continuous dust removal and filtration process of the dust removal sheet 2, due to the different environments of the sections where the protective device body 1 is set, the dust content of the airflow entering the protective device body 1 is also very different;

[0049] When the section where the protective device body 1 is set is in an environment with heavy dust, the initially set back-blowing parameters cannot effectively act on the dust removal sheet 2, resulting in the blockage of the dust removal sheet 2 after long-term use, and the dust removal sheet 2 becomes blocked. Then, the airflow entering the protective device body 1 through the dustproof outer cover 12 blows the dust removal sheet 2 under the continuous action of the ventilation fan. Under the resistance of the dust removal sheet 2 after blockage, the ventilation baffle 41 and the elastic clamping sleeve 3 move toward the side away from the dustproof outer cover 12, driving the elastic guide sleeve 44 and the reset elastic member 46 to shrink and deform, so that the trigger column 45 inside them gradually approaches the sensing column 43. After the sensing column 43 is triggered by the trigger column 45, a blockage trigger signal is sent to the blockage sensing unit, and the blockage sensing unit transmits the blockage trigger data to the dustproof ventilation processing unit. On the one hand, the dustproof ventilation processing unit transmits the back-blowing control data to the back-blowing control unit, so that the back-blowing control unit increases the control effect on the ventilation fan. When the ventilation fan generates back-blowing When in use, the dust removal sheet 2 loses the dragging effect of the intake airflow, and the elastic recovery effect of the elastic clamping sleeve 3, the elastic guide sleeve 44 and the reset elastic member 46 will drive the dust removal sheet 2 and the ventilation baffle 41 to produce a reset movement, and gradually restore the position close to the dustproof outer cover 12. Therefore, during the back-blowing effect, the dust and impurities on the dust removal sheet 2 will be discharged through the dustproof outer cover 12, and the mobility of the dust removal sheet 2 and the elastic clamping sleeve 3 will be increased by intermittent blowing, and the treatment effect of the blockage of the dust removal sheet 2 will be further promoted to ensure the stability of the operation of the power metering equipment inside the protective device body 1, and after the back-blowing control unit processes the blocked dust removal sheet 2, the back-blowing control unit stops the reverse control effect on the ventilation fan, so that the blowing fan returns to a normal ventilation state, so that the airflow enters the protective device body 1 through the dustproof outer cover 12, the dust removal sheet 2 and the baffle sheet 21, and can also assist the dust-proof ventilation processing unit in judging the effectiveness of the treatment of the blockage of the dust removal sheet 2 according to whether the blockage sensing unit is triggered;

[0050] On the other hand, the dust-proof ventilation processing unit also synchronously transmits the blockage data and the back-blowing data of the blockage processing of the dust removal piece 2 to the remote signal transmission unit, so that the remote signal transmission unit transmits the data to the section data analysis and processing unit. The section data analysis and processing unit analyzes and judges the environment of the section where the protective device body 1 is set after receiving the blockage data and the back-blowing and internal environment data obtained in the early stage, and then transmits the back-blowing cycle control instruction to the personalized dust-proof control unit. The personalized dust-proof control unit transmits the personalized control data to the remote dust-proof data receiving unit. After receiving the back-blowing control data transmitted by the remote dust-proof data receiving unit, the dust-proof ventilation processing unit promptly issues data instructions to the back-blowing control unit to optimize the back-blowing cycle and parameters, so as to ensure the effectiveness of the back-blowing effect, reduce the blockage probability of the dust removal piece 2, ensure the continuous effectiveness of the dust removal filtration of the dust removal piece 2, and effectively ensure the protective effect of the protective device body 1;

[0051] When the road section where the protective device body 1 is set is in an environment with less dust, the initially set backflush parameters can effectively act on the dust removal sheet 2 to ensure its dust-proof ventilation effect, so that the dust removal sheet 2 will not be blocked and triggered. The dust-proof ventilation processing unit will transmit the ventilation data it receives to the remote signal transmission unit. The road section data analysis and processing unit analyzes the road section environment where the protective device body 1 is set according to the full dust-proof ventilation data transmitted by the remote signal transmission unit, and downgrades the initial backflush control parameters. By extending the backflush cycle, the energy loss of the protective device body 1 is reduced, and then the downgraded data is transmitted to the personalized The dust control unit, the personalized dust control unit transmits data to the dust ventilation processing unit through the remote signal transmission unit, so that the dust ventilation processing unit acts on the back-blowing control unit to control the back-blowing control cycle, while ensuring the effectiveness of the dust prevention measures of the protective device body 1, reducing the energy loss of the protective device body 1 during the dust prevention ventilation process, promoting the environmental protection of the protective device body 1, and thus effectively realizing the applicability of the protective device body 1 to different setting environments, promoting the automation and intelligence of the protective effect of the protective device body 1, reducing the difficulty and cost of maintenance, and promoting the economy of the application of the protective device body 1;

[0052] And during the subsequent application of the protective device body 1, the road section analysis and processing unit will also transmit the backflush data, blockage data and ventilation data of the protective device body 1 to the dustproof maintenance display unit, so that the dustproof maintenance display unit can display the protection data of the protective device body 1 through the display of the power metering maintenance platform, so that the maintenance personnel can effectively observe the status of the protective device body 1, while reducing the difficulty of maintenance and labor costs, it can also effectively promote maintenance efficiency and timeliness, and ensure the safety of the protective application of the protective device body 1.

[0053] Second implementation method:

[0054] Figure 1 - Figure 6 and Figure 8 - Fig.10 A protective device for electric power metering equipment for electric power marketing is shown, and a plurality of traction lines 51 evenly distributed along the length direction of the elastic clamping sleeve 3 are hinged on the inner wall thereof, and the traction lines 51 are located between the dust removal sheet 2 and the baffle sheet 21, and an oscillation ball 5 is rotatably connected to the lower end of the traction line 51. The setting of the oscillation ball 5 and the traction line 51 can produce a knocking and vibration effect on the dust removal sheet 2 or the baffle sheet 21 when the ventilation fan is in effect, and further promote the falling of dust and impurities adhered thereto by increasing the mobility of the dust removal sheet 2 and the baffle sheet 21, thereby effectively ensuring the dustproof and ventilation effect of the protective device body 1 while reducing the probability of clogging of the dust removal sheet 2.

[0055] Figure 8 It is shown that a dust removal strip hole 31 corresponding to the position of the oscillation ball 5 is opened at the lower end of the elastic clamping sleeve 3, and a dust box 32 is installed at the lower end of the dust removal strip hole 31. The cooperation between the dust removal strip hole 31 and the dust box 32 can effectively collect the dust and impurities shaken off by the oscillation ball 5, avoid the accumulation of dust on the elastic clamping sleeve 3, and cause subsequent pollution to the partition plate 21 and the power metering equipment inside the protective device body 1, effectively ensure the protective effect of the protective device body 1, and promote the durability of the protective device body 1.

[0056] Figure 1 - Figure 6 and Figure 8 - Fig.10 It is shown that an auxiliary lamp bead is fixedly installed on the lower end of the oscillation ball 5, and a photosensitive probe matching the auxiliary lamp bead is fixedly installed on the lower inner wall of the dust box 32. A transparent dust collecting plate located on the upper end of the photosensitive probe is detachably connected in the dust box 32. The detachable connection method here can be bolt connection, buckle connection, sliding connection, etc. After a certain amount of dust is collected on the upper end of the transparent dust collecting plate, it can be taken out to remove the dust. The input end of the dust-proof ventilation processing unit is also connected to a dust collection status acquisition unit, and the input end of the dust collection status acquisition unit is connected to the photosensitive probe signal. The auxiliary lamp bead, the photosensitive probe and the dust collection status acquisition unit are connected. The setting of the unit, on the one hand, can assist the road section data analysis and processing unit to collect data on the setting environment of the protective device body 1, increase the data basis for adjusting the applicability of the dust prevention and ventilation measures of the protective device body 1 through the personalized dust prevention control unit, and promote the accuracy and effectiveness of its applicability control; on the other hand, it can also assist the power metering maintenance platform to maintain the protective device body 1. When there is a lot of dust accumulated in the dust box 32, it is processed in time to avoid the pollution of the baffle plate 21 and the power metering equipment inside the protective device body 1 by a lot of dust, thereby ensuring the protection effect of the protective device body 1.

[0057] Figure 2It is shown that the output end of the dustproof ventilation processing unit is also connected to a ventilation and dust removal control unit, and the output end of the ventilation and dust removal control unit is connected to the ventilation fan signal arranged in the protective device body 1. The setting of the ventilation and dust removal control unit can effectively cooperate with the vibration effect of the vibration ball 5 to achieve the knocking effect of intermittent blowing on the vibration ball 5, thereby effectively increasing the durability of the dust removal sheet 2 and the partition sheet 21, promoting its dustproof adsorption effect, and ensuring the ventilation and dust removal protective effect of the protective device body 1.

[0058] Figure 1 - Figure 6 and Figure 8 - Fig.10 It is shown that during the application of the dust removal sheet 2, when a blockage state occurs, the sensing column 43 transmits the blockage data to the dust-proof ventilation processing unit through the blockage sensing unit. After the dust-proof ventilation processing unit independently controls the back-blowing control unit and instructs it to produce a back-blowing effect, the blockage sensing unit is triggered again so that the dust-proof ventilation processing unit determines that the back-blowing effect is not good. After the dust removal sheet 2 remains blocked, the dust-proof ventilation processing unit transmits a drying instruction to the drying dust-proof unit on the one hand, so that the drying dust-proof unit controls the electric heating wire to be energized, and dries the baffle sheet 21 and the dust removal sheet 2 to reduce the adhesion of dust and impurities;

[0059] On the other hand, the control instruction will be transmitted to the ventilation and dust removal control unit at the same time, and the ventilation and dust removal control unit will control the ventilation fan. First, the ventilation fan will be controlled to flip and generate a larger rotation speed, so that the airflow blows the oscillation ball 5 gradually close to the dust removal sheet 2 and squeezes the dust removal sheet 2. Then, the rotation speed of the ventilation fan will be reduced to generate a smaller wind speed, and the blowing effect on the baffle sheet 21 will be kept small. At the same time, the oscillation ball 5 will swing under the action of gravitational potential energy; and after the oscillation ball 5 swings for a period of time, the rotation speed of the ventilation fan will continue to increase to squeeze the kinetic energy of the oscillation ball 5. The vibration ball 5 is energized to promote the swing amplitude and frequency of the vibration ball 5, and this is repeated many times, so that the vibration ball 5 continuously knocks and vibrates the baffle plate 21 and the dust removal plate 2, so that the dust and impurities blocked on the dust removal plate 2 and adhered to the baffle plate 21 are removed, and under the action of the ventilation fan, the problem of dust and impurities flying toward the inside of the protective device body 1 is avoided, while the blockage of the dust removal plate 2 is effectively regulated, the protective effect of the protective device body 1 is guaranteed, and then the dust that is shaken off will fall into the dust box 32 through the dust discharge strip hole 31 and be collected by the transparent dust collecting plate;

[0060] After the ventilation and dust removal control unit performs vibration and shedding processing on the dust removal piece 2, the dust prevention and ventilation processing unit determines that the dust removal piece 2 is in a blocked state through the blockage sensing unit. After the dust removal piece 2 is no longer blocked, the full data of the dust prevention and ventilation is transmitted to the remote signal transmission unit. The remote signal transmission unit transmits the data to the section data analysis and processing unit, so that the section data analysis and processing unit transmits further back-blowing cycle control to the personalized dust prevention control unit. The personalized dust prevention control unit transmits the data to the dust prevention and ventilation processing unit through the remote dust prevention data receiving unit, so that the dust prevention and ventilation processing unit can further adjust the control data of the back-blowing control unit, the ventilation and dust removal control unit and the drying dust prevention unit to ensure the intelligent control of the protective device body 1 of the set section and ensure the continuous effectiveness of its dust prevention and ventilation.

[0061] And as the transparent dust collecting plate at the upper end of the dust box 32 collects dust and impurities, the light transmittance of the transparent dust collecting plate is reduced, so that the photosensitive probe can no longer effectively sense the light of the auxiliary lamp bead, and then the photosensitive probe transmits the photosensitive data to the dust collection status acquisition unit, the dust collection status acquisition unit transmits the photosensitive data to the dustproof ventilation processing unit, the dustproof ventilation processing unit transmits the data to the section data analysis and processing unit through the remote signal transmission unit, the section data analysis and processing unit displays the data to the maintenance personnel through the display through the dustproof maintenance display unit architecture, which can effectively facilitate the maintenance personnel to check the status of the protective device body 1, and process the dust box 32 in a timely and effective manner to avoid dust accumulation and pollution to the inside of the protective device body 1.

[0062] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
