Technical Field

[0001] The invention relates to the field of switch cabinet environment control, and in particular to a low-voltage withdrawable switch cabinet dehumidification method, system and switch cabinet. Background Art

[0002] Low-voltage withdrawable switchgear is a complete set of equipment used in low-voltage power distribution systems, mainly used for the distribution, control and protection of electric energy. It adopts a withdrawable structural design, that is, each functional unit (such as circuit breaker unit, contactor unit, fuse unit, etc.) can be withdrawn or inserted from the cabinet like a drawer, which is convenient for inspection, maintenance and replacement without affecting the normal operation of other units.

[0003] During the use of low-voltage withdrawable switchgear, it is usually necessary to impose certain restrictions on the humidity around and inside the switchgear. Nowadays, workers can limit the humidity inside the switchgear by using sealed switchgear, causing the humidity inside the switchgear to be as low as a standard value.

[0004] When using a sealed switch cabinet, sealing strips are usually used to seal the remaining gaps in the switch cabinet door cabinet. Once the sealing strips are damaged, the sealing effect will be greatly reduced, which may cause the humidity in the cabinet to exceed the standard, thereby increasing the probability of accident risks in the switch cabinet due to excessive humidity, which needs to be improved. Summary of the invention

[0005] In order to reduce the probability of accident risks due to excessive humidity in a switch cabinet, the present invention provides a low-voltage withdrawable switch cabinet dehumidification method, system and switch cabinet.

[0006] In a first aspect, the present invention provides a method for dehumidifying a low-voltage withdrawable switch cabinet, which adopts the following technical solution: A dehumidification method for a low-voltage withdrawable switch cabinet, comprising: Get the internal humidity value of the switch cabinet; Based on the situation that the internal humidity value exceeds the preset reference internal humidity value, controlling the blowing device preset in the switch cabinet to blow air inside the switch cabinet with a preset blowing force value, and obtaining the internal air pressure value; Based on the situation that the internal air pressure value is lower than the preset reference air pressure value, obtaining ultrasonic detection information of the preset sealing strip position; Matching the leak position from a preset sound wave database according to the ultrasonic detection information, the preset reference sound wave detection information and the sealing strip position; Controlling the preset repair device to fill the preset repair material to the leaking position with the preset repair material dosage; After the repair, the preset dehumidification device is controlled to reduce the internal humidity value of the switch cabinet to below the reference humidity value using a preset dehumidification method.

[0007] By adopting the above technical solution, the humidity inside the switch cabinet can be known by understanding the excess between the internal humidity value and the reference internal humidity value. When the switch cabinet is too humid, the blowing device is controlled to blow air inside the switch cabinet, and the excess between the internal air pressure value and the reference air pressure value is understood to understand the damage of the sealing strip. When the sealing strip is damaged, the corresponding repair is carried out by understanding the leakage position, and after the repair is completed, the dehumidification device is controlled to remove the moisture inside the switch cabinet. In this way, the probability of accident risks due to excessive humidity in the switch cabinet is reduced.

[0008] Optionally, the method for determining the amount of repair material includes: Match the leakage range from the sound wave database according to the ultrasonic detection information and the reference sound wave detection information; Matching the quantity of support materials from a preset material database according to the air leakage range and the preset support material size; Match placement parameters from the preset support database according to the number of support materials; Controlling the repair device to place the supporting materials corresponding to the number of supporting materials to the leaking position according to the placement parameters; After placement is completed, the amount of repair material and the repair position are matched from the preset repair database according to the leakage range, the size of the support material and the placement parameters; The repair device is controlled to fill the repair material to the repair position according to the amount of repair material used, so as to provide temporary use for the sealing strip.

[0009] By adopting the above technical solution, by understanding the ultrasonic detection information and the reference sound wave detection information, the leakage range can be known, and then the amount of supporting materials and the placement parameters can be known, and the supporting materials can be placed at the leakage position. Through the known placement parameters, the amount of repair material and the repair position can be further known, so that the repair device can be controlled to repair the leakage position, which improves the repair efficiency while also improving the repair stability.

[0010] Optional dehumidification methods include: Based on the situation that the internal humidity value exceeds the reference internal humidity value, obtaining the ambient humidity value of the preset switch cabinet placement area; Based on the condition that the ambient humidity value does not exceed the preset reference ambient humidity value, the preset ventilation equipment is turned on to accelerate the ventilation of the switch cabinet; Based on the situation that the ambient humidity value exceeds the reference ambient humidity value, calculating the difference between the internal humidity value and the reference internal humidity value as the dehumidification humidity value; Matching a dehumidification power value from a preset dehumidification database according to the dehumidification humidity value; Based on the dehumidification power value, a preset dehumidification device is controlled to start, so as to reduce the internal humidity value in the switch cabinet to below the reference internal humidity value.

[0013] By adopting the above technical solution, the humidity inside the switch cabinet can be known by understanding the excess between the absorption humidity value and the reference absorption value. When the switch cabinet is too humid, the humidity impact range can be known by understanding the absorption humidity value, and then the specific over-humidification position and dehumidification bulb position can be known, so as to remind the staff and reduce the probability of accident risks caused by excessive humidity in the switch cabinet.

[0014] Optional replacement methods include: According to the position of the dehumidifying ball, the number of the pre-positioned dehumidifying balls is matched from the preset moisture absorption database; Determine the number of replacement balls according to the number of pre-placed dehumidification balls and the total number of preset dehumidification balls placed; According to the number of replacement balls, a preset replacement device is controlled to place a dehumidifying ball along a preset dehumidifying ball replacement pipeline, so as to push the front dehumidifying ball into the dehumidifying ball replacement pipeline; Based on the situation that the number of the front dehumidification balls is zero, the preset drying channel is opened; After the drying channel is opened, the dehumidification ball at the dehumidification ball position is sent into a preset drying area to be dried by a preset drying method.

[0015] By adopting the above technical solution, the number of replacement balls is known by knowing the number of front dehumidification balls, and the opening status of the spin-drying channel is known by knowing the remaining number of front dehumidification balls. When the spin-drying channel needs to be opened, the replacement balls remaining for replacing the dehumidification balls are placed into the dehumidification ball replacement pipeline by controlling the replacement device, so that the dehumidification balls enter the spin-drying area through the spin-drying channel so as to be spin-dried, thereby improving the utilization rate of the dehumidification balls.

[0016] Optionally, a preset replacement verification method is also included, and the replacement verification method includes: After the dehumidification ball corresponding to the dehumidification ball position is replaced, the absorption humidity value of the dehumidification ball is obtained again after a preset reference time, and the absorption humidity value obtained again is defined as the new ball humidity value; Based on the situation that the humidity value of the new ball exceeds the reference absorption value, the image information inside the cabinet is obtained; According to the image information inside the cabinet, the specific over-humidity position and the preset characteristics inside the cabinet, the damage range is selected from the preset damage database and the damage position is marked; Based on the situation that the damage range exceeds the preset reference range, the isolation number is matched from the preset isolation database according to the damage location; Control the isolation baffle corresponding to the isolation number in the preset switch cabinet to start, so as to isolate the damaged position; Based on the situation that the damage range does not exceed the reference range, the amount of plugging material is matched from the preset plugging database according to the damage range; The preset blocking device is controlled to spray the preset blocking material on the damaged position with the blocking material dosage, and the preset blowing device is controlled to blow the damaged position with the preset blowing wind force value.

[0017] By adopting the above technical solution, the abnormality of humidity in the cabinet can be known by understanding the excess between the new ball humidity value and the reference absorption value. When the humidity in the cabinet is abnormal, the damage range and damage location can be known by understanding the image information in the cabinet. Then, by understanding the excess between the damage range and the reference range, the protection method can be known. Thus, the protection effect is improved and the material usage is reduced.

[0018] Optional drying methods include: Obtain a trigger signal of a spin drying area; Based on the fact that the trigger signal is consistent with the preset placement signal, a weight detection value of the dehumidification ball is obtained; Matching the spin speed from a preset spin database according to the weight detection value and the absorbed humidity value; Control the preset drying device to spin the dehumidifying bulb at a spinning speed, and control the preset drying device to blow and dry the dehumidifying bulb at a preset drying temperature to remove the humidity in the dehumidifying bulb; After the moisture removal of the dehumidifying ball is completed, the preset clamping device is controlled to place the dehumidifying ball into the dehumidifying ball replacement pipe.

[0019] By adopting the above technical solution, the placement of the spin-drying area is known by understanding the consistency between the trigger signal and the placement signal. When a dehumidifying ball is placed in the spin-drying area, the spin-drying speed is known by understanding the weight detection value and the absorbed humidity value, and then the spin-drying device is controlled to spin-dry the dehumidifying ball, and then the dehumidifying ball is blown and dried by the drying device to improve the dryness of the dehumidifying ball, and finally the dehumidifying ball is placed in the dehumidifying ball replacement pipeline by controlling the clamping device to improve the utilization rate of the dehumidifying ball.

[0020] Optionally, an algorithm formula for calculating the spin speed is also included, and the algorithm formula is: n=1 / (2π)*√F 阻 / {(m 物 +α*m 物 )r}, where n is the spin speed, π is the circumference, F 阻 is the adhesion force of moisture on the surface of the dehumidifying ball, m 物 is the weight test value, α is the moisture absorption rate of the dehumidifying bulb, α*m 物 is the absorbed humidity value, and r is the radius of the circular motion of the dehumidifying ball.

[0021] By adopting the above technical solution and using the above algorithm formula, the spin speed can be calculated more accurately, thereby avoiding incomplete spinning due to too low a spin speed or excessive energy consumption due to too high a spin speed.

[0022] In a second aspect, the present application provides a low-voltage withdrawable switch cabinet dehumidification system, which adopts the following technical solution: A low-voltage withdrawable switch cabinet dehumidification system, comprising: Acquisition module, used for internal humidity value, internal air pressure value, ultrasonic detection information, ambient humidity value, absorbed humidity value, cabinet image information, trigger signal and weight detection value; A memory, used to store a program of any one of the above-mentioned low-voltage withdrawable switch cabinet dehumidification methods; The processor is used to load, execute and implement the program stored in the memory.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] The embodiment of the present application discloses a dehumidification method for a low-voltage withdrawable switch cabinet. By understanding the internal humidity value, the damage of the sealing strip is known. When the sealing strip is damaged, the sealing strip is repaired by using a repair method, and a dehumidification method is selected based on the ambient humidity value of the switch cabinet placement area. The internal humidity condition is known by understanding the absorption humidity value of the internal dehumidification bulb. When the dehumidification bulb needs to be replaced, the corresponding replacement method is known by understanding the position of the dehumidification bulb, and the replaced dehumidification bulb is dried for reuse.

[0028] Reference Figure 1 , a low-voltage withdrawable switch cabinet dehumidification method, comprising the following steps: Step 100: Obtain the internal humidity value of the switch cabinet.

[0029] The internal humidity value refers to the humidity value inside the switch cabinet when the cabinet door of the switch cabinet is closed. The switch cabinet in this embodiment is a sealed switch cabinet. The internal humidity value is measured and obtained by a humidity sensor in the switch cabinet.

[0030] Step 101: Based on the situation that the internal humidity value exceeds the preset reference internal humidity value, control the blowing device preset in the switch cabinet to blow air to the inside of the switch cabinet with a preset blowing force value, and obtain the internal air pressure value.

[0031] The reference internal humidity value refers to the maximum allowable humidity value inside the switch cabinet. The blowing device refers to a device used to blow air into the switch cabinet to detect the sealing of the switch cabinet. The blowing force value refers to the wind force used by the blowing device to blow air into the switch cabinet. The reference internal humidity value and the blowing force value are both set in advance by technicians in this field and are not described here. The internal air pressure value refers to the air pressure intensity inside the switch cabinet. The internal air pressure value is measured and obtained by the air pressure sensor inside the switch cabinet.

[0032] When the internal humidity value exceeds the benchmark internal humidity value, it indicates that the inside of the switch cabinet is too humid. It is necessary to control the blowing device in the switch cabinet to blow air to the inside of the switch cabinet at the blowing force value, and obtain the internal air pressure value to detect the sealing condition of the switch cabinet.

[0033] Step 102: based on the situation that the internal air pressure value is lower than the preset reference air pressure value, obtaining ultrasonic detection information of the preset sealing strip position.

[0034] The reference air pressure value refers to the value that the air pressure inside the switch cabinet should reach after the switch cabinet is blown with the blowing force value. The sealing strip position refers to the specific position where the sealing strip is attached to the switch cabinet. The reference air pressure value and the sealing strip position are both set in advance by those skilled in the art and are not described here. Ultrasonic detection information refers to the intensity and frequency of ultrasonic detection of the sealing strip position. Ultrasonic detection information is obtained by measuring with an ultrasonic leak detector.

[0035] When the internal air pressure value is lower than the reference air pressure value, it indicates that the sealing condition of the switch cabinet is abnormal, and ultrasonic detection information of the sealing strip position needs to be obtained for subsequent steps.

[0036] Step 103: Match the leak position from a preset sound wave database according to the ultrasonic detection information, the preset reference sound wave detection information and the sealing strip position.

[0037] The reference sound wave detection information refers to the intensity and frequency when ultrasonic detection is performed on the sealing strip position where no damage occurs. The reference sound wave detection information is set in advance by a person skilled in the art and will not be described in detail here. The leakage position refers to the position of the damaged sealing strip. The ultrasonic detection information, the reference sound wave detection information and the leakage position corresponding to the sealing strip position can be matched through the sound wave database, which contains the correspondence between the ultrasonic detection information, the reference sound wave detection information, the sealing strip position and the leakage position. The sound wave database is a manually set database and will not be described in detail here.

[0038] Step 104: Control the repair device to fill the preset repair material to the leaking position with the preset repair material dosage.

[0039] The repair device refers to a device used to repair the leaking position. The amount of repair material refers to the amount of repair material needed to repair the leaking position. The specific amount of repair material is described in detail in the subsequent steps 200 to 205 and will not be repeated here. The repair material refers to the material used to repair the leaking position. The specific repair material is set in advance by those skilled in the art and will not be repeated here. The amount of repair material used in the repair device is controlled to fill the leaking position with the repair material, thereby repairing the leaking position for subsequent steps.

[0040] Step 105: After repair, control the preset dehumidification device to reduce the internal humidity value of the switch cabinet to below the reference humidity value using a preset dehumidification method.

[0041] The dehumidification device refers to a device used to dehumidify the inside of the switch cabinet. The dehumidification method refers to a method used to dehumidify the inside of the switch cabinet.

[0042] After the leak is repaired, the dehumidification device is controlled to reduce the internal humidity value of the switch cabinet to below the reference humidity value by dehumidification method.

[0043] Reference Figure 2 , the method for determining the amount of repair material includes the following steps: Step 200: Match the leakage range from the sound wave database according to the ultrasonic detection information and the reference sound wave detection information.

[0044] The leakage range refers to the range of leakage caused by the damage of the sealing strip, and is also the damage range of the sealing strip. The ultrasonic detection information and the reference acoustic wave detection information can be matched to the leakage range, which includes the correspondence between the ultrasonic detection information and the reference acoustic wave detection information and the leakage range.

[0045] Step 201: Match the amount of supporting material from a preset material database according to the air leakage range and the preset supporting material size.

[0046] The size of the supporting material refers to the size of the material used to support the repair material for plugging the leaking position. The size of the supporting material is set in advance by a person skilled in the art and will not be described in detail here. The amount of the supporting material refers to the amount of the material used to support the repair material for plugging the leaking position.

[0047] The material database can be used to match the leakage range and the supporting material size corresponding to the supporting material quantity, which includes the corresponding relationship between the leakage range and the supporting material size and the supporting material quantity. The material database is an artificially set database and will not be elaborated here.

[0048] Step 202: Match placement parameters from a preset support database according to the quantity of support materials.

[0049] The placement parameters refer to placing the support materials at the leaking position to better support the specific placement of the repair materials. The support database can be used to match the placement parameters corresponding to the number of support materials, which contains the corresponding relationship between the number of support materials and the placement parameters. The support database is a manually set database and will not be described here.

[0050] Step 203: Controlling the repair device to place the supporting materials corresponding to the number of supporting materials at the leaking position according to the placement parameters.

[0051] The robot arm on the repair device is controlled to clamp the supporting materials corresponding to the number of supporting materials to the leaking position, and the supporting materials are placed according to the placement parameters for subsequent steps.

[0052] Step 204: After placement is completed, the amount of repair material and the repair position are matched from a preset repair database according to the leakage range, the size of the support material and the placement parameters.

[0053] The repair position refers to the position where the repair material repairs the leak. After the support material is placed, the repair database is needed to match the leak range, support material size, and placement parameters corresponding to the repair material amount and repair position for subsequent steps. The repair database contains the correspondence between the leak range, support material size, placement parameters, repair material amount, and repair position. The repair database is a manually set database and will not be described here.

[0054] Step 205: Control the repair device to fill the repair material to the repair position according to the amount of repair material used, so as to provide temporary use for the sealing strip.

[0055] The repair device is controlled to fill the repair material to the repair position according to the amount of repair material, so as to seal the leaking position, and the sealing strip can be used temporarily until the subsequent staff replaces the sealing strip.

[0056] Reference Figure 3 , the dehumidification method comprises the following steps: Step 300: Based on the situation that the internal humidity value exceeds the reference internal humidity value, obtain the ambient humidity value of the preset switch cabinet placement area.

[0057] The switch cabinet placement area refers to the specific geographical location where the switch cabinet is placed. It is set in advance by those skilled in the art and will not be described in detail here. The ambient humidity value refers to the humidity value in the air in the switch cabinet placement area. The ambient humidity value can be measured by a humidity sensor.

[0058] When the internal humidity value exceeds the benchmark internal humidity value, it means that the inside of the switch cabinet is too humid, and the ambient humidity value of the switch cabinet placement area needs to be obtained for subsequent steps.

[0059] Step 301: based on the fact that the ambient humidity value does not exceed a preset reference ambient humidity value, start a preset ventilation device to accelerate ventilation of the switch cabinet.

[0060] The reference ambient humidity value refers to the maximum humidity value in the air when the switch cabinet is placed in a dry state. The reference ambient humidity value is set in advance by those skilled in the art and will not be described in detail here. The ventilation equipment refers to equipment used to ventilate the inside of the switch cabinet to remove moisture from the switch cabinet. The ventilation equipment is installed on the switch cabinet. When the ventilation equipment is not needed, the ventilation equipment is in a closed state to ensure that the switch cabinet is sealed.

[0061] When the ambient humidity value does not exceed the benchmark ambient humidity value, it means that the current switch cabinet placement area is in a dry state. The ventilation equipment can be turned on to accelerate the ventilation speed inside the switch cabinet to better ventilate and dehumidify the inside of the switch cabinet.

[0062] Step 302: Based on the situation that the ambient humidity value exceeds the reference ambient humidity value, a difference between the internal humidity value and the reference internal humidity value is calculated as a dehumidification humidity value.

[0063] The dehumidification humidity value refers to the value at which moisture needs to be removed from the inside of the switch cabinet. The dehumidification humidity value can be obtained by calculating the difference between the internal humidity value and the reference internal humidity value.

[0064] When the ambient humidity value exceeds the benchmark ambient humidity value, it means that the area where the switch cabinet is placed is in a humid state, and the ventilation equipment cannot be turned on to ventilate and dehumidify the interior of the switch cabinet. The dehumidification humidity value needs to be calculated for subsequent steps.

[0065] Step 303: matching a dehumidification power value from a preset dehumidification database according to the dehumidification humidity value.

[0066] The dehumidification power value refers to the power value required by the dehumidification device used to remove moisture inside the switch cabinet. The dehumidification device refers to a device used to remove moisture inside the switch cabinet. When ventilation equipment cannot be used to ventilate and dehumidify the inside of the switch cabinet, a dehumidification device is required to remove moisture inside the switch cabinet. The dehumidification power value corresponding to the dehumidification humidity value can be matched through the dehumidification database, which contains the corresponding relationship between the dehumidification humidity value and the dehumidification power value. The dehumidification database is a manually set database and will not be described here.

[0067] Step 304: Based on the dehumidification power value, a preset dehumidification device is controlled to start, so as to reduce the internal humidity value in the switch cabinet to below the reference internal humidity value.

[0068] The dehumidification device is controlled to start with the matched dehumidification power value, so as to reduce the internal humidity value in the switch cabinet to below the reference internal humidity value.

[0069] Reference Figure 4 , the daily dehumidification method includes the following steps: Step 400: Obtain the absorbed humidity value of the dehumidifying bulb preset in the switch cabinet.

[0070] The dehumidifier bulb is an object placed in the interlayer of the switch cabinet to absorb moisture in the switch cabinet. The dehumidifier bulb is hollow, and particles for absorbing moisture are placed inside the dehumidifier bulb. There are evenly distributed air holes on the outer shell of the dehumidifier bulb, and the size of the particles is larger than the size of the air holes. The absorbed humidity value refers to the humidity value absorbed by the dehumidifier bulb itself.

[0071] The interlayer is provided with an area for placing dehumidifying balls, and there are multiple holes for placing dehumidifying balls in the area, so multiple dehumidifying balls can be placed in the area at the same time, and the multiple dehumidifying balls are arranged linearly, each hole of the dehumidifying ball is provided with a different number, and each hole of the dehumidifying ball is provided with a humidity sensor for measuring the absorbed humidity value of the dehumidifying ball on the hole. Therefore, the absorbed humidity value is measured and obtained by the humidity sensor on the hole.

[0072] Step 401: Based on the situation that the absorbed humidity value exceeds a preset reference absorption value, determine the humidity influence range according to the absorbed humidity value.

[0073] The reference absorption value refers to the value at which the dehumidifying bulb can no longer absorb moisture in the switch cabinet. The reference absorption value is set in advance by a person skilled in the art and will not be described in detail here. The humidity influence range refers to the influence range of the wetting factors that cause the dehumidifying bulb to be unable to continue to absorb moisture. The humidity influence range corresponding to the absorption humidity value can be matched through the preset over-humidification database, which includes the corresponding relationship between the absorption humidity value and the humidity influence range. The over-humidification database is a manually set database and will not be described in detail here.

[0074] When the absorbed humidity value exceeds the reference absorption value, it means that the dehumidifying bulb can no longer continue to absorb moisture in the switch cabinet, and the humidity influence range needs to be matched for subsequent steps.

[0075] Step 402: Match a specific over-humidity position from a preset over-humidity database according to the humidity impact range.

[0076] The specific over-humidity position refers to the position of the wet factor that causes the dehumidifying bulb to be unable to continue to absorb moisture. The over-humidity database can be used to match the specific over-humidity position corresponding to the humidity influence range, which includes the corresponding relationship between the humidity influence range and the absorbed humidity value and the specific over-humidity position.

[0077] Step 403: Control the preset prompt device to report the specific over-humidity position and determine the dehumidification bulb position according to the humidity impact range.

[0078] The reminder device is a device used to remind the staff that there is an over-humidified position in the switch cabinet. The dehumidifier position is the position where it can no longer absorb moisture in the switch cabinet. The preset dehumidifier database can be used to match the hole number corresponding to the humidity influence range, and then the dehumidifier position corresponding to the hole number can be known. The dehumidifier database contains the correspondence between the humidity influence range and the hole number. The dehumidifier database is a manually set database and will not be described here.

[0079] Based on the specific over-humidity position, the control prompt device reports a prompt to remind the staff of the specific location of the over-humidity situation in the switch cabinet, and then matches the dehumidification bulb position from the dehumidification bulb database for subsequent steps.

[0080] Step 404: Control a preset replacement device to replace the dehumidification ball at the dehumidification ball position using a preset replacement method.

[0081] The replacement device refers to a device used to replace the dehumidifying bulb in the hole. The replacement method refers to a method for replacing a dehumidifying bulb that can no longer absorb moisture inside the switch cabinet. The replacement method is described in detail in the subsequent steps 500 to 505, and will not be described in detail here.

[0082] The control replacement device replaces the dehumidification bulb that can no longer absorb moisture inside the switch cabinet by a replacement method, so that a new dehumidification bulb is used to absorb moisture inside the switch cabinet.

[0083] Reference Figure 5 , the replacement method comprises the following steps: Step 500: Match the number of pre-positioned dehumidification bulbs from a preset moisture absorption database according to the position of the dehumidification bulbs.

[0084] The number of front dehumidifier bulbs refers to the number of dehumidifier bulbs in front of the dehumidifier bulb that needs to be replaced. The number of front dehumidifier bulbs corresponding to the dehumidifier bulb position can be matched through the moisture absorption database, which contains the corresponding relationship between the dehumidifier bulb position and the number of front dehumidifier bulbs. The moisture absorption database is a manually set database and will not be described here.

[0085] The example illustrates the dehumidification ball replacement process. When there are 5 holes for the dehumidification ball, the holes are numbered 1, 2, 3, 4, and 5 in order. When the dehumidification ball on hole 5 needs to be replaced, a new dehumidification ball needs to be placed in hole 1, causing the dehumidification ball on hole 2 to move to hole 3, and the dehumidification ball on hole 3 to move to hole 4, and then the dehumidification ball on hole 5 is squeezed out of the hole. When the dehumidification ball on hole 3 needs to be replaced, 3 new dehumidification balls need to be placed in order to squeeze the dehumidification ball in hole 3 out of all holes.

[0086] Step 501: Determine the number of replacement balls according to the number of pre-placed dehumidification balls and the total number of preset dehumidification balls to be placed.

[0087] The total number of dehumidifying bulbs placed refers to the total number of dehumidifying bulbs placed in the interlayer set on the switch cabinet. The total number of dehumidifying bulbs placed is also the total number of holes opened. The number of replacement balls refers to the number of dehumidifying bulbs used to replace the holes. The replacement ball refers to the object used to replace the dehumidifying bulb in the hole. The replacement ball is also a dehumidifying ball. When the replacement ball is placed in the hole, the name is redefined as a dehumidifying ball. When the dehumidifying ball is replaced out of the hole, the name is defined as a replacement ball. The preset replacement database can be used to match the number of replacement balls corresponding to the number of pre-dehumidifying bulbs and the total number of dehumidifying bulbs placed, which includes the corresponding relationship between the number of pre-dehumidifying bulbs, the total number of dehumidifying bulbs placed, and the number of replacement balls. The replacement database is a manually set database and will not be described here.

[0088] Step 502: According to the number of replacement balls, a preset replacement device is controlled to place the dehumidifier balls along the preset dehumidifier ball replacement pipeline, so as to push the front dehumidifier balls into the dehumidifier ball replacement pipeline.

[0089] The replacement device refers to a device used to replace the dehumidifying bulb in the hole. The dehumidifying bulb replacement pipe refers to a pipe used to place the replacement ball to replace the dehumidifying bulb in the hole. When the dehumidifying bulb replaced out of the hole does not need to be spun dry, it will flow into the dehumidifying bulb replacement pipe again.

[0090] The control replacement device puts the replacement balls corresponding to the number of replacement balls into the dehumidification ball replacement pipeline, so that the dehumidification balls in front of the dehumidification balls that need to be replaced can be pushed into the dehumidification ball replacement pipeline.

[0091] Step 503: Based on the situation that the number of the front dehumidification bulbs is zero, the preset spin-drying channel is opened.

[0092] The drying channel is a channel for sending the dehumidification ball to a preset drying area. The drying area is an area for removing moisture from the dehumidification ball. The drying area is set in advance by a person skilled in the art and will not be described in detail here.

[0093] When the number of the front dehumidification balls is zero, it means that the next dehumidification ball to be pushed out of the hole is the dehumidification ball at the original dehumidification ball position, and the spin-drying channel needs to be opened for subsequent steps.

[0094] Every time a dehumidification ball is pushed out of the hole, the number of the front dehumidification balls will be reduced by one until the number of the front dehumidification balls is zero.

[0095] Step 504: After the drying channel is opened, the dehumidification ball at the dehumidification ball position is sent into a preset drying area to dry the dehumidification ball using a preset drying method.

[0096] The drying method is a method for drying the dehumidifying bulbs whose absorption humidity value exceeds the reference absorption value so as to continue to use them. The drying method is described in detail in the subsequent steps 700 to 705 and will not be described in detail here.

[0097] When the spin-drying channel is opened, the replacement device is controlled to place the last replacement ball for replacing the dehumidification ball into the hole of the dehumidification ball, so as to push the dehumidification ball at the dehumidification ball position into the spin-drying channel, and then enter the dehumidification area through the spin-drying channel, and spin dry the dehumidification ball in the dehumidification area by the spin-drying method for subsequent use.

[0098] Reference Figure 6 , the replacement verification methods include: Step 600: After the dehumidification ball corresponding to the dehumidification ball position is replaced, the absorption humidity value of the dehumidification ball is obtained again after a preset reference time, and the absorption humidity value obtained again is defined as the new ball humidity value.

[0099] The reference time refers to the unit time used to re-detect the absorbed humidity value of the dehumidifying bulb at the dehumidifying bulb position. The reference time is set in advance by a person skilled in the art and will not be described in detail here. The new ball humidity value refers to the absorbed humidity value of the new dehumidifying bulb at the dehumidifying bulb position after the dehumidifying bulb corresponding to the dehumidifying bulb position is replaced. The new ball humidity value is obtained by measuring the humidity sensor at the dehumidifying bulb position.

[0100] Replace the dehumidifying ball corresponding to the dehumidifying ball position, and after the reference time has passed, obtain the absorption humidity value of the dehumidifying ball at the dehumidifying ball position again, and define the absorption humidity value obtained again as the new ball humidity value for subsequent steps.

[0101] Step 601: Based on the situation that the humidity value of the new ball exceeds the reference absorption value, the image information inside the cabinet is obtained.

[0102] The image information inside the cabinet refers to the image inside the switch cabinet. The image information inside the cabinet is obtained by taking pictures with a camera. When the humidity value of the new ball exceeds the reference absorption value, it means that the new dehumidifying ball replaced in the position of the dehumidifying ball can no longer absorb the moisture inside the switch cabinet, which means that the switch cabinet is damaged and the image information inside the cabinet needs to be obtained for subsequent steps.

[0103] Step 602: select the damage range from a preset damage database and mark the damage location according to the image information inside the cabinet, the specific over-humidity location and the preset features inside the cabinet.

[0104] The in-cabinet features refer to the features inside the switch cabinet. The in-cabinet features are set in advance by technicians in this field and will not be described in detail here. The damage range refers to the size of the area where the switch cabinet is damaged. The damage location refers to the location where the switch cabinet is damaged. Through the damage database, the specific over-humidity location and the in-cabinet features can be compared from the in-cabinet image information to select the damage range, and the damage location can be marked. The damage database contains the correspondence between the in-cabinet image information, the specific over-humidity location, the in-cabinet features, the damage range and the damage location. The damage database is a manually set database and will not be described in detail here.

[0105] Step 603: Based on the situation that the damage range exceeds the preset reference range, an isolation number is matched from a preset isolation database according to the damage position.

[0106] The reference range refers to the range used to determine whether the damage range of the switch cabinet is too large. The reference range is set in advance by a person skilled in the art and will not be described in detail here. The isolation number refers to the number of the isolation baffle that covers and isolates the damage range when the damage range of the switch cabinet is too large. The isolation baffle refers to an object used to cover and isolate the damage range. In this embodiment, there are multiple isolation baffles in the switch cabinet, and each isolation baffle has a corresponding number. Different numbers are responsible for isolating different damaged locations.

[0107] The isolation database can be used to match the isolation number corresponding to the damaged location. It contains the corresponding relationship between the damaged location and the isolation number. The isolation database is a manually set database and will not be described here. When the damage range exceeds the reference range, it means that the damage range of the switch cabinet is too large and the isolation number needs to be matched for subsequent steps.

[0108] Step 604: Control the isolation baffle corresponding to the isolation number in the preset switch cabinet to start up to isolate the damaged position.

[0109] The isolation baffle corresponding to the isolation number in the control switch cabinet is activated to isolate the damaged position, thereby protecting various components in the switch cabinet.

[0110] Step 605: Based on the fact that the damage range does not exceed the reference range, the amount of plugging material is matched from a preset plugging database according to the damage range.

[0111] The amount of sealing material refers to the amount of material required to seal the damaged position. When the damage range does not exceed the reference range, it means that the damage range of the switch cabinet is not too large, and the preset sealing material can be used directly for sealing. The sealing material refers to the material used to seal the damaged position. The sealing material is set in advance by those skilled in the art and will not be described in detail here. The amount of sealing material corresponding to the damage range can be matched through the blocking database, which contains the corresponding relationship between the damage range and the amount of sealing material. The blocking database is an artificially set database and will not be described in detail here.

[0112] Step 606: Control the preset blocking device to spray the preset blocking material on the damaged position with the blocking material dosage, and control the preset blowing device to blow the damaged position with the preset blowing wind force value.

[0113] The plugging device refers to a device used to apply a plugging material to a damaged position to plug the damaged position. The blowing device refers to a device used to blow air to the damaged position sprayed with the plugging material, and the blowing wind force value refers to the wind force value used to blow air to the damaged position sprayed with the plugging material. The blowing wind force value is set in advance by a person skilled in the art and will not be described in detail here.

[0114] The plugging equipment is controlled to spray the applied amount of plugging material on the damaged position to plug the plugging material, and after the spraying is completed, the blowing equipment is controlled to blow the damaged position at the blowing wind force value to accelerate the curing of the plugging material.

[0115] Reference Figure 7 The drying method comprises the following steps: Step 700: Obtain a trigger signal of a spin-drying area.

[0116] The trigger signal refers to the signal sent by the signal transceiver on the spin-drying area. The trigger signal includes an empty signal and a placement signal. The empty signal refers to the signal sent when there is no dehumidifying ball placed in the spin-drying area, and the placement signal refers to the signal sent when a dehumidifying ball is placed in the spin-drying area. Both the empty signal and the placement signal are set in advance by those skilled in the art and will not be described in detail here. The trigger signal is obtained by the signal transceiver on the spin-drying area.

[0117] Step 701: based on the fact that the trigger signal is consistent with the preset placement signal, the weight detection value of the dehumidification bulb is obtained.

[0118] The weight detection value refers to the original weight value of the dehumidifying bulb when it does not absorb moisture. The weight detection value can be obtained by calling the preset weight database. The weight database contains the weight detection value of the dehumidifying bulb. The weight database is a manually set database and will not be described here.

[0119] When the trigger signal is consistent with the placement signal, it means that a dehumidifying ball that needs to be spun is placed in the drying area, and the weight detection value of the dehumidifying ball needs to be obtained for subsequent steps.

[0120] Step 702: Match the spin speed from a preset spin database according to the weight detection value and the absorbed humidity value.

[0121] The spin speed refers to the speed used to spin the dehumidifying bulb. The spin speed corresponding to the weight detection value and the absorbed humidity value can be matched through the spin database, which contains the algorithm formula for calculating the spin speed: n=1 / (2π)*√F 阻 / {(m 物 +α*m 物 )r}, where n is the spin speed, π is the circumference, F 阻 is the adhesion force of moisture on the surface of the dehumidifying ball, m 物 is the weight test value, α is the moisture absorption rate of the dehumidifying bulb, α*m 物 is the absorbed humidity value, and r is the radius of the circular motion of the dehumidifying ball.

[0122] F 阻 , α and r are measured in advance by those skilled in the art, and will not be described in detail here. π is selected by those skilled in the art according to actual conditions, and will not be described in detail here. The drying database is a manually set database, and will not be described in detail here.

[0123] Step 703: Control the preset drying device to spin the dehumidification bulb at a spinning speed, and control the preset drying device to blow and dry the dehumidification bulb at a preset drying temperature to remove the humidity in the dehumidification bulb.

[0124] The drying device refers to a device for drying the dehumidifying bulb. The drying device refers to a device for further drying the dehumidifying bulb, and the drying temperature refers to the temperature at which the drying device further dries the dehumidifying bulb. The drying temperature is set in advance by a person skilled in the art and will not be described in detail here.

[0125] The spin-drying device is controlled to rotate at a spin-drying speed to drive the dehumidifying ball to rotate in the spin-drying device, thereby drying the dehumidifying ball. When the spin-drying device rotates, the drying device is controlled to blow and dry the dehumidifying ball at a drying temperature to remove the humidity in the dehumidifying ball.

[0126] Step 704: After the moisture removal of the dehumidification bulb is completed, the preset clamping device is controlled to place the dehumidification bulb into the dehumidification bulb replacement pipe.

[0127] The clamping device is a device used to clamp the completely dehumidified dehumidifying bulb to the dehumidifying bulb replacement pipe. All dehumidifying bulbs in the dehumidifying bulb replacement pipe are temporarily defined as replacement balls. When the moisture removal of the dehumidifying bulb is completed, the clamping device is controlled to put the dehumidifying bulb into the dehumidifying bulb replacement pipe for subsequent use.
