[0016] In summary, the present application includes at least one of the following beneficial technical effects: 1. When it is necessary to mark the wind speed of the electric fan, the moving tube is moved to the inside of the box and the marking tube is pushed toward the outside of the moving tube. The marking tube drives the balloon out of the moving tube. At this time, the air pump starts to blow air into the regulating tube. As the air is blown into the balloon, the balloon begins to float up due to the buoyancy. The balloon is set upward. When there is a lot of dust on the blades of the electric fan, the rotation of the electric fan will be hindered, resulting in a decrease in air volume and wind speed. The balloon only shakes. Therefore, as long as the balloon shakes, it proves that the wind speed of the electric fan has not reached the set state, and the dust affects the wind speed of the electric fan. 2. When the air gun moves to the tail end of the blade of the electric fan, if it continues to move, the air gun is facing the blade of the impeller. Due to the high air pressure in the cylinder, the impeller immediately rotates, and the impeller drives the limiting disk to start rotating. The infrared receiver cannot receive the signal from the infrared transmitter. At this time, the buzzer starts to alarm, and the air gun and the control component are stopped immediately. This is the maximum distance the air gun can move. Start to control the approach and start to move. The electromagnet at the front end is powered off and the electromagnet at the rear end adsorbs the sliding rod. The two-way electric cylinder drives the adsorption block at the front end to move. After the electromagnet at the front end moves to the specified position, the electromagnet is energized, and the electromagnet at the front end adsorbs the sliding rod. The electromagnet at the rear end starts to be powered off, and the electromagnet at the rear end starts to move forward under the action of the two-way electric cylinder. By analogy, the driving effect of the proximity switch is realized until the proximity switch moves to contact with the cleaning block and stops. If the cleaning block drives the air gun to move to the specified position, that is, when it contacts the proximity switch, it needs to stop moving. 3. The driving block is controlled to move upward through the driving member. Under the support of the connecting rod, the adsorption sheet expands outward, and the adsorption sheet drives the electrostatic dust removal paper to expand and adsorb the dust. When the electrostatic dust removal paper completes or does not complete the cleaning work, the two winding rollers are controlled to rotate, and the electrostatic dust removal paper can be replaced to continue to adsorb dust, or the electrostatic dust removal paper adsorbed with dust can be wound and collected to complete the cleaning of the electric fan. Finally, the protective cover is rotated, the locking rod is rotated outside the box, and the protective cover is opened until it does not affect the normal operation of the electric fan.

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] Embodiment 1

[0021] The present application embodiment discloses an intelligent box-type substation and a box-type substation internal air conditioning method. Figure 1-Figure 3 An intelligent box-type substation and an internal air conditioning method of the box-type substation include a station body 1, a refrigeration device, a dehumidification device, a humidity sensor and a temperature sensor. An electric fan 2, a detection device for detecting whether dust is accumulated on the electric fan 2, and a cleaning device for removing dust from the electric fan 2 are also arranged in the box body 3; in this embodiment, the humidity or temperature in the station body 1 is monitored by a humidity sensor or a temperature sensor. If the temperature exceeds the set value, it is necessary to cool down by the refrigeration device, and the cooling effect is accelerated by the electric fan 2. When the humidity sensor monitors that the humidity in the station body 1 exceeds the set value, dehumidification is required. In addition, the refrigeration device and the dehumidification device can both use equipment in the prior art, and dehumidification and cooling will not interfere with each other. As long as it is found that the temperature or humidity exceeds the set value, corresponding processing is required.

[0022] When there is a lot of dust accumulated on the blades of the electric fan 2, the rotation of the electric fan 2 will be hindered, resulting in a decrease in air output and a decrease in wind speed, because the dust will fill the gaps between the fan blades, reducing the area of ​​air circulation, and also increasing the resistance to the fan rotation. Therefore, when too much dust accumulates on the blades of the electric fan 2, the effect of accelerating the air flow rate becomes worse. Therefore, by detecting the air flow rate, it can be determined whether the fan blades need to be cleaned, which is usually observed by staff. First of all, it is not convenient for staff to observe the electric fan 2 on site. In addition, the staff can only see the presence of dust on the blades of the electric fan 2 by observation, and cannot determine whether the blades affect the accelerated air flow.

[0023] Reference Figure 1-Figure 3 The detection device includes a box body 3 fixedly arranged outside the electric fan 2, an identification mechanism for identifying the wind speed of the electric fan 2, and an observation mechanism for the staff to observe the wind speed of the electric fan 2; the top and bottom ends of the box body 3 are both opened. First, the dust on the blades of the electric fan 2 is marked by the identification mechanism, and then the staff can observe the wind speed through the observation mechanism. In this embodiment, the observation of the wind speed does not need to be accurate to a specific value, and it is only necessary to observe that the wind speed is significantly lower than the wind speed of the electric fan 2 when it is initial and not covered with dust.

[0024] The marking mechanism includes a balloon 4 movably arranged in the box body 3, a moving component for controlling the movement of the balloon 4 and an adjusting component for evacuating / deflating the balloon 4; the balloon 4 is movably arranged below the electric fan 2, and the electric fan 2 blows directly at the balloon 4. The balloon 4 will not be inflated in the initial state and will only be inflated when it is located below the electric fan 2. The moving component includes a moving part 5, a moving tube 6 slidably arranged on the side wall of the box body 3 and an marking tube 7 slidably arranged in the moving tube 6. The air inlet of the balloon 4 is tied to the end of the marking tube 7. The moving part 5 is realized by an electric push rod or a cylinder in this embodiment. Similarly, the movement of the marking tube 7 is also realized by an electric push rod. In this embodiment, the moving part 5 is located on the side wall of the moving tube 6, and the electric push rod corresponding to the marking tube 7 is also located on the side wall of the marking tube 7, that is, the center position of the marking tube 7 and the moving tube 6 needs to be reserved.

[0025] The regulating assembly includes an air pump 9 and a regulating tube 8, one end of the regulating tube 8 is connected to the output end of the air pump 9, the other end of the regulating tube 8 penetrates into the box body 3, the moving tube 6 and the marking tube 7, and the regulating tube 8 passes through the central axis of the moving tube 6 and the marking tube 7 until the regulating tube 8 passes through the marking tube 7 and then extends into the balloon 4, the air pump 9 can inflate and deflate, the air pump 9 is placed in the external environment, the regulating tube 8 is made of soft material and the length of the regulating tube 8 needs to ensure that the marking tube 7 and the moving tube 6 can move; when the wind speed of the electric fan 2 needs to be marked, by moving the moving tube 6 to the box body, The marking tube 7 is inserted into the interior of the body 3 and pushed toward the outside of the moving tube 6. The marking tube 7 drives the balloon 4 to move out of the moving tube 6. At this time, the air pump 9 starts to blow air into the adjusting tube 8. As air is blown into the balloon 4, the balloon 4 begins to float due to the buoyancy. That is, the balloon 4 is set upward. In this embodiment, if the wind speed blown out by the electric fan 2 is the wind speed in the initial state, the balloon 4 can be blown downward. When the wind speed is small, the balloon 4 only shakes. Therefore, as long as the balloon 4 shakes, it proves that the wind speed of the electric fan 2 has not reached the set state, and the dust affects the wind speed blown out by the electric fan 2.

[0026] Reference Figure 1-Figure 3 The observation mechanism includes an observation plate 10, a light source 11, a screen 12 and a camera 13. The box body 3 is provided with an observation port 14 on the opposite side wall of the moving tube 6. The observation plate 10 is rotatably arranged in the observation port 14. The light source 11 is installed on one side of the observation plate 10. The screen 12 is arranged on the opposite side wall of the light source 11. The box body 3 is provided with a mounting port for installing the screen 12. The screen 12 is installed at the opening of the mounting port. The camera 13 is installed in the mounting port and faces the screen 12. The position set by the light source 11 faces the floating position of the balloon 4 after inflation. What is displayed on the screen 12 is the projection of the balloon 4. Therefore, the camera 13 only needs to shoot the projection of the balloon 4, and there is no need to directly shoot and observe the balloon 4. This can not only improve the efficiency of observation, but also prevent the camera 13 from being affected by dust. If the camera 13 captures that the projection of the balloon 4 on the screen 12 is shaking instead of swinging downward, it proves that there is a problem with the wind speed blown out by the electric fan 2, and the blades on the electric fan 2 need to be cleaned.

[0027] The cleaning device includes a plurality of air guns 15, a compressor for supplying air to the air guns 15 at the same time, a control component for controlling the movement of the nozzle, a locking component for locking the blades of the electric fan 2, and an adsorption component for adsorbing the cleaned dust, the nozzle moves along the extension direction of the fan blade, the compressor is arranged in the external environment, and the air gun 15 is inclined and the inclination angle is less than 10°. In this embodiment, the number of air guns 15 is preferably set to two, and the two air guns 15 are respectively facing the front and back sides of the blades. The output end of the compressor is connected to the two air guns 15 through a two-way adapter, so that In order to achieve the effect of supplying air to two air guns 15 at the same time, the compressor is set in the external environment, and the tilted air gun 15 is more conducive to blowing away the dust. However, if the tilt angle is too large, it will affect the use effect of the air gun 15, which is not conducive to thoroughly cleaning the blades of the electric fan 2. The locking component is used to ensure that the blades of the electric fan 2 and only one blade of the electric fan 2 are located directly below the air gun 15. The air gun 15 moves along the extension direction of the blades of the electric fan 2, which is more conducive to thoroughly removing the dust, and the adsorption component adsorbs the blown dust. The two air guns 15 are located on the same side of the electric fan 2.

[0028] Reference Figure 1-Figure 3The control component includes a slide bar 16 fixedly connected to the housing 3, a cleaning block 17 slidably mounted outside the slide bar 16, a control member 18 for driving the cylinder to reciprocate, and a limiting portion for setting the movement distance of the air gun 15. The air gun 15 is fixed on the cleaning block 17. The two slide bars 16 are respectively located on the upper and lower sides of the blades of the electric fan 2. The control member 18 can be an electric push rod or a cylinder. The limiting portion is used to limit the movement distance of the air gun 15, that is, the air gun 15 in this embodiment can use blades of different specifications of the electric fan 2, which is more adaptable; the limiting portion includes an impeller 19 rotatably connected to the housing 3, a limiting disk 20 coaxially fixed to the impeller 19, an infrared transmitter 21, an infrared receiver 22, a proximity switch 23, a slider 24 slidably mounted outside the slide bar 16, a bidirectional electric cylinder 25, two adsorption blocks 26, and two electromagnets 27. The slide bar 16 is arranged in the horizontal direction, and the impeller 1 9 is perpendicular to the rotation axis of the electric fan 2, a limiting cavity is provided on the inner wall of the box body 3, the impeller 19 is located in the box body 3 and the limiting disk 20 rotates in the limiting cavity, and a limiting hole 28 is provided on the end face of the limiting plate. In the initial state, the signal emitted by the infrared transmitter 21 is received by the infrared receiver 22 after passing through the limiting hole 28, and the infrared receiver 22 is electrically connected to the buzzer 29, and the infrared receiver 22 is controlled and connected with the buzzer 29 through the PLC controller. When the air gun 15 moves to the tail end of the blade of the electric fan 2, if it continues to move, the air gun 15 is facing the blade of the impeller 19. Due to the high air pressure in the cylinder, the impeller 19 immediately rotates, and the impeller 19 drives the limiting disk 20 to start rotating. The infrared receiver 22 cannot receive the signal of the infrared transmitter 21. At this time, the buzzer 29 starts to alarm, and the operation of the air gun 15 and the control component 18 is immediately stopped. At this time, the maximum distance of the air gun 15 movement.

[0029] The shell of the bidirectional electric cylinder 25 is fixed on the slider 24, and the two output ends of the bidirectional electric cylinder 25 are fixedly connected to the two adsorption blocks 26 respectively. The electromagnet 27 is fixed on the adsorption block 26 and is used to adsorb the slide bar 16. The proximity switch 23 is fixed on the slider 24. When the maximum distance of the cylinder movement has been determined, the proximity control starts to start the movement, the electromagnet 27 at the front end is powered off and the electromagnet 27 at the rear end adsorbs the slide bar 16. The bidirectional electric cylinder 25 drives the adsorption block 26 at the front end to move. After the electromagnet 27 at the front end moves to the specified position, the electromagnet 27 is powered on, the electromagnet 27 at the front end adsorbs the slide bar 16, and the electromagnet 27 at the rear end starts to be powered off. Under the action of the two-way electric cylinder 25, it starts to move forward, and so on, to achieve the driving effect of the proximity switch 23, until the proximity switch 23 moves to contact with the cleaning block 17 and then stops. If the cleaning block 17 subsequently drives the air gun 15 to move to the specified position, that is, when it contacts with the proximity switch 23, it is necessary to stop the movement; the reason why the movement of the proximity switch 23 in this embodiment does not use an electric push rod or an air cylinder is that, firstly, the electromagnet 27 can be adsorbed or disconnected at any time, and the operation is convenient. In addition, the space where the drive of the proximity switch 23 is located is limited, and the electric push rod cannot be well installed and connected. Finally, the staff can control the movement distance of the proximity switch 23 at any time, and can accurately locate the position of the proximity switch 23.

[0030] Reference Figure 2-Figure 4The locking assembly includes a rotating rod 30 coaxially fixedly connected to the bottom of the rotating shaft of the electric fan 2, a protective frame 31 slidably arranged at the bottom of the box body 3, a protective cover 32 rotatably arranged on the protective frame 31, a lifting rod 33 lifted and lowered on the protective cover 32, and a locking rod 34 lifted and lowered at the top of the lifting rod 33. A cross opening 35 is provided at the bottom end of the rotating rod 30, and a cross block 36 is fixedly connected to the top of the locking rod 34. The cross block 36 is inserted into the cross opening 35. In the initial state, the protective frame 31 is located at the outside of the opening at the bottom end of the box body 3, and the locking rod 34 and other structures are located at the bottom end of the protective cover 32. While ensuring that the operation of the electric fan 2 in the box body 3 is not affected, it can also ensure that the subsequent locking rod 34 can smoothly enter the box body 3. The axis of rotation of the protective cover 32 and the protective frame 31 is located at the protective On the symmetrical surface of the protective cover 32, the driving of the protective cover 32 is realized by a motor, and the lifting and lowering of the lifting rod 33 and the locking rod 34 are realized by an electric push rod. In this embodiment, it is set that the angle of each movement of the blades of the electric fan 2 is the same, and the blades of the electric fan 2 can be moved to the bottom of the air gun 15, and at this time the cross block 36 is just aligned with the cross opening 35. Of course, in this embodiment, the connection method between the cross block 36 and the cross opening 35 can also be replaced with an electromagnet adsorption method. When the electromagnet is energized, the locking rod 34 locks the rotating rod 30, and when the electromagnet is de-energized, the locking rod 34 and the rotating rod 30 are released. When the locking rod 34 locks the rotating rod 30, the blades of the electric fan 2 can be cleaned. At this time, the protective cover 32 has blocked the box body 3, and dust will not fall into the cabinet.

[0031] Reference Figure 2-Figure 4 The adsorption component includes two adsorption sheets 37, a driving part for controlling the unfolding of the adsorption sheets 37, an electrostatic dust removal paper 38 movably arranged on the adsorption disk, and a winding part for controlling the movement of the electrostatic dust removal paper 38. The upper end of the adsorption sheet 37 is hinged to the outer wall of the locking rod 34 and the axial direction of the hinge shaft is horizontally set. The driving part includes a driving block 40 slidably set on the outside of the locking rod 34, a driving member 41 for controlling the lifting and lowering of the driving block 40, and a connecting rod 42. One end of the connecting rod 42 is hinged to the driving block 40, and the other end of the connecting rod 42 is hinged to the adsorption sheet 37, and the position where the connecting rod 42 and the adsorption sheet 37 are hinged is located in the middle of the adsorption sheet 37. The two adsorption sheets 37 are symmetrically arranged relative to the central axis of the locking rod 34. In the initial state, the adsorption sheet 37 is located on the outside of the protective cover 32. After the adsorption sheet 37 is opened, the contact area between the electrostatic dust removal paper 38 and the dust in the box body 3 can be greatly increased, thereby quickly cleaning the dust in the box body 3.

[0032] The driving member 41 can be an electric push rod or a cylinder. The driving member 41 is installed on the outside of the locking rod 34. The winding part includes two winding rollers 39 and two winding motors. The interior of the adsorption sheet 37 is set as a winding chamber, and the winding chamber is provided with two through slots for the electrostatic dust removal paper 38 to pass through. The winding roller 39 rotates in the winding chamber. The winding motor is installed in the winding chamber and is used to control the rotation of the winding roller 39. The two ends of the electrostatic dust removal paper 38 are respectively fixedly connected to the outer walls of the two winding rollers 39. The two winding motors rotate at the same frequency and in the same direction, thereby controlling the replacement of the electrostatic dust removal paper 38 leaking on the outside of the adsorption sheet 37; when the air gun 15 starts to clean the dust When the electrostatic dust removal paper 38 is cleaned, the two winding rollers 39 are controlled to rotate, and the electrostatic dust removal paper 38 can be replaced, and the dust can continue to be adsorbed, or the electrostatic dust removal paper 38 adsorbed with dust can be wound and collected to complete the cleaning of the electric fan 2. Finally, the protective cover 32 is rotated, the locking rod 34 is rotated to the outside of the box body 3, and the protective cover 32 is opened until it will not affect the normal operation of the electric fan 2.

[0033] The implementation principle of an intelligent box-type substation and an internal air conditioning method of a box-type substation according to an embodiment of the present application is as follows: when it is necessary to mark the wind speed of the electric fan 2, by moving the mobile tube 6 to the inside of the box body 3 and pushing the marking tube 7 toward the outside of the mobile tube 6, the marking tube 7 drives the balloon 4 to move out of the mobile tube 6. At this time, the air pump 9 starts to blow air into the regulating tube 8. As air is blown into the balloon 4, due to the buoyancy, the balloon 4 begins to float up, that is, the balloon 4 is set upward. When there is a lot of dust on the blades of the electric fan 2, the rotation of the electric fan 2 will be hindered, resulting in a decrease in air output and a decrease in wind speed. The balloon 4 only shakes. Therefore, as long as the balloon 4 is shaking, it proves that the wind speed of the electric fan 2 has not reached the set state, and the dust affects the wind speed blown out by the electric fan 2.

[0034] When the air gun 15 moves to the tail end of the blade of the electric fan 2, if it continues to move, the air gun 15 will face the blade of the impeller 19. Due to the high air pressure in the cylinder, the impeller 19 will immediately rotate, and the impeller 19 will drive the limiting disk 20 to start rotating. The infrared receiver 22 cannot receive the signal from the infrared transmitter 21. At this time, the buzzer 29 starts to alarm, and the air gun 15 and the control part 18 will stop working immediately. This is the maximum distance that the air gun 15 can move. The control starts to approach and start moving. The electromagnet 27 at the front end is powered off and the electromagnet 27 at the rear end adsorbs the slide bar 16. The bidirectional electric cylinder 25 drives the adsorption block 26 at the front end to move. After the electromagnet 27 at the front end moves to the specified position, the electromagnet 27 is energized, and the electromagnet 27 at the front end adsorbs the slide bar 16. The electromagnet 27 at the rear end begins to be de-energized, and the electromagnet 27 at the rear end begins to move forward under the action of the bidirectional electric cylinder 25, and so on, to achieve the driving effect of the proximity switch 23 until the proximity switch 23 moves to contact with the cleaning block 17 and stops. If the cleaning block 17 drives the air gun 15 to move to the specified position later, that is, when it contacts with the proximity switch 23, it needs to stop moving.

[0035] The driving block 40 is controlled to move upward by the driving member 41. Under the support of the connecting rod 42, the adsorption sheet 37 is expanded outward, and the adsorption sheet 37 drives the electrostatic dust removal paper 38 to expand and adsorb dust. When the electrostatic dust removal paper 38 completes or does not complete the cleaning work, the two winding rollers 39 are controlled to rotate, so that the electrostatic dust removal paper 38 can be replaced, and the dust can continue to be adsorbed, or the electrostatic dust removal paper 38 adsorbed with dust can be wound and collected to complete the cleaning of the electric fan 2. Finally, the protective cover 32 is rotated, the locking rod 34 is rotated to the outside of the box body 3, and the protective cover 32 is opened until it will not affect the normal operation of the electric fan 2.

[0036] Embodiment 2

[0037] The present application embodiment discloses a method for air conditioning inside a box-type substation. Figure 1 A method for air conditioning inside a box-type substation comprises the following steps: Preparation: Clean the electric fan 2, clean the blades of the electric fan 2 with the air gun 15 and adsorb the dust with the electrostatic dust removal paper 38; use the moving air gun 15 to clean the blades of the electric fan 2, and at the same time lock the rotating rod 30 with the locking rod 34. After the dust cleaning process, the driving member 41 is required to control the driving block 40 to move upward. Under the support of the connecting rod 42, the adsorption sheet 37 is unfolded outward, and the adsorption sheet 37 drives the electrostatic dust removal paper 38 to unfold and adsorb the dust, thereby completing the cleaning effect of the blades of the electric fan 2; When the humidity sensor detects that the cabinet humidity exceeds the set value, dehumidification equipment is required for dehumidification; When the temperature sensor recognizes that the temperature inside the cabinet exceeds the set value, it is necessary to turn on or accelerate the rotation of the electric fan 2 to quickly cool down the cabinet. The above temperature control and humidity control actions are not prioritized and require timely response, so that the temperature and humidity inside the cabinet can be accurately controlled.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
