Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic environment monitoring, and in particular to a device and method for monitoring the electromagnetic environment of a high-voltage power transmission and transformation project. Background Art

[0002] The harm of electromagnetic radiation to the human body is manifested in two aspects: thermal effect and non-thermal effect. Thermal effect: when the human body is exposed to electromagnetic radiation, the molecules in the body will move rapidly with the conversion of the electromagnetic field, causing the human body to heat up. The thermal effect can cause dysfunction of the central nervous system and the vegetative mental system, mainly manifested as dizziness, insomnia, forgetfulness and other sub-healthy performances. Non-thermal effect: the absorption of radiation is not enough to cause an increase in body temperature, but it also causes physiological changes and reactions. Living and working in this environment for too long will cause clinical symptoms such as dizziness, fatigue, memory loss, and loss of appetite. Only by systematically monitoring and analyzing the characteristics of electromagnetic radiation changes around high-voltage AC transmission and substations and proposing electromagnetic radiation prevention and optimization measures can the harm caused by electromagnetic radiation to humans be effectively reduced.

[0003] However, when performing electromagnetic environment monitoring on high-voltage power transmission and transformation projects, if the working environment of the electromagnetic radiation monitoring instrument is relatively humid, the air environment inside the shell of the electromagnetic radiation monitoring instrument will be relatively humid. When the internal humidity exceeds a certain level, it will condense into water droplets, which will drip onto the internal electrical components of the electromagnetic radiation monitoring instrument, thus easily causing electrical short circuits. In the prior art, desiccant is often used to dry the air inside the electromagnetic radiation monitoring instrument. However, after the desiccant is saturated, it needs to be replaced frequently manually, which not only shortens the replacement cycle, but also significantly increases the workload of maintenance personnel.

When the separating plate starts to move, the large-diameter section of the T-shaped rod is in movable contact with the other end of the large-diameter hole.

[0013] As a preferred solution of the electromagnetic environment monitoring device for high-voltage power transmission and transformation projects of the present invention, wherein: the inserting component includes a fixing plate fixedly connected to the top of the support plate.

[0014] A monitoring method using the above electromagnetic environment monitoring device for high-voltage power transmission and transformation projects includes the following steps: Step 1: When drying the inside of the electromagnetic radiation monitoring instrument, start the air extraction pump. The air extraction pump operates to draw the moisture inside the electromagnetic radiation monitoring instrument into the drying box. The moisture is first dried by the desiccant box at the bottom of the drying box, and then successively dried by the stacked desiccant boxes above. Finally, it enters the intake pipe through the air inlet and outlet hole on one side of the desiccant box at the top of the drying box, and then the dried gas is introduced into the electromagnetic radiation monitoring instrument to complete the drying; Step 2: After using for a period of time, when it is necessary to discharge the desiccant box at the bottom of the drying box from the drying box, start the driving motor. The output end of the driving motor drives the first lead screw to rotate. The first lead screw drives the small gear to rotate. The moving block moves along the first lead screw away from the drying box under the limiting action of the U-shaped plate, the first sealing plate, and the second sealing plate. The moving block drives the U-shaped plate to move along. The U-shaped plate drives the first sealing plate, the second sealing plate, and the T-shaped rod to move along. When the first sealing plate and the second sealing plate are gradually opened and the openings at the upper and lower ends of the drying box are all exposed, the desiccant box at the bottom of the drying box falls into the used desiccant box storage box under its own gravity, while the second-to-last desiccant box in the drying box is supported by the partition plate and will not fall into the used desiccant box storage box; Step 3: During the process of opening the openings at the upper and lower ends of the drying box, the large-diameter section of the T-shaped rod slides in the large-diameter hole. When the large-diameter section of the T-shaped rod contacts the end of the large-diameter hole away from the drying box, the openings at the upper and lower ends of the drying box are opened. When the U-shaped plate is continuously driven to move by the driving motor, the U-shaped plate continues to drive the first sealing plate, the second sealing plate, and the T-shaped rod to move along. The T-shaped rod pulls the partition plate to move outward by contacting the end of the large-diameter hole away from the drying box. During the process of the partition plate moving outward step by step, the lifting rod first contacts the first inclined surface at one end of the limit release rod. After the contact, when the lifting rod continues to move, under the action of the first inclined surface, the lifting rod pulls the abutting rod to move upward. When the abutting rod separates from the vertical rod, the vertical rod moves toward the drying box under the restoring force of the first spring. The telescopic plate also moves out of the storage groove and intersects with the opening at the bottom of the drying box under the restoring force of the first spring to prevent the desiccant box from falling again. At this time, the partition plate has not completely separated from the bottom of the second-to-last desiccant box. Then, the partition plate is continuously driven to retreat by the driving motor. When the partition plate completely separates from the bottom of the second-to-last desiccant box, the desiccant boxes in the drying box move downward as a whole. Due to the limiting action of the telescopic plate, when the desiccant boxes in the drying box move downward as a whole, they will not fall out of the drying box; Step 4: Additionally, during the process of opening the upper and lower openings of the drying box, the small gear rotates, driving the large gear meshed with it to rotate. The large gear drives the second lead screw to rotate in the direction opposite to that of the first lead screw, so that the moving directions of the insertion rod and the first sealing plate are opposite. During the process of gradually opening the first sealing plate, the insertion rod, through the action of its tip, inserts into the gap between the two lowermost desiccant boxes in the spare storage box, for limiting the penultimate desiccant box in the spare storage box. When the bottom end of the spare storage box and the top end of the drying box are fully opened, the lowermost desiccant box in the spare storage box falls into the drying box under the action of its own gravity, thus achieving the purpose of automatically replenishing the desiccant box in the drying box; Step 5: When closing the first sealing plate and the second sealing plate again, the driving motor drives the first lead screw to rotate in the direction opposite to the previous one, causing the moving block to drive the U-shaped plate to move towards the drying box. The U-shaped plate drives the first sealing plate, the second sealing plate, and the T-shaped rod to move accordingly. When the large diameter section of the T-shaped rod contacts the end of the large diameter hole close to the drying box, the separating plate is driven to insert into the drying box again through the contact force and support at the bottom of the penultimate desiccant box. The two first sealing plates block between the spare storage box and the drying box. During the process of the two second sealing plates approaching each other, through the extrusion force, the telescopic plate is squeezed into the storage groove. The telescopic plate drives the vertical rod to move away from the drying box through the moving rod, and through the cooperation of the arc structure at the top end of the vertical rod and the arc structure at the bottom of the abutting rod, the abutting rod moves upward. When the vertical rod passes through the abutting rod, the abutting rod moves downward and resets under the resilience of the second spring and limits the vertical rod; During the process of gradually closing the two first sealing plates, the insertion rod is gradually withdrawn from the bottom of the lowermost desiccant box in the spare storage box. When it is completely separated from the desiccant box, all the desiccant boxes in the spare storage box move downward as a whole, waiting for the next replenishment of the desiccant box into the drying box.

[0015] Advantages of the present invention: In the present invention, through the combined use of an air extraction pump, an air extraction pipe, an air inlet pipe, a drying box, a desiccant box, etc., the moisture inside the electromagnetic radiation monitoring instrument can be introduced into the drying box. After being dried by the desiccant inside the desiccant box, it is introduced back into the electromagnetic radiation monitoring instrument, so that it is not easy for the electromagnetic radiation detection instrument to have a short circuit situation.

[0016] In the present invention, a driving motor drives a first lead screw to rotate, so that a U-shaped plate drives a first sealing plate, a second sealing plate, a T-shaped rod, etc. to move away from the drying box, thereby being able to open the first sealing plate and the second sealing plate, causing the desiccant box that first contacts moisture in the drying box to fall into the used desiccant box storage box. When the T-shaped rod moves and drives the partition plate to be pulled out of the drying box, all the desiccant boxes in the drying box move downward. When moving downward, the lowermost desiccant box in the spare storage box is replenished into the drying box, thereby being able to automatically replace the saturated desiccant boxes step by step. Only when all the desiccant boxes in the spare storage box are used up does manual intervention need to be carried out for replenishment and maintenance. This process has a long cycle and can significantly reduce the workload of maintenance personnel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0022] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0023] Reference Figure 1-16 , which is the first embodiment of the present invention, provides an electromagnetic environment monitoring device for a high-voltage power transmission and transformation project, mainly comprising: like Figure 1 The main unit 100 includes a base 101, a support rod 102 fixedly connected to the top of the base 101, and an electromagnetic radiation monitoring instrument 103 fixedly connected to the front side of the support rod 102. The drying box 201 is a top-to-bottom connecting structure, and the left and right sides of the drying box 201 are fixedly connected with a first guide sleeve 202; like Figure 3 The exhaust component includes an exhaust pipe 203, an air inlet pipe 204 and an exhaust pump 205. One end of the exhaust pipe 203 is fixedly connected to the lower side of the drying box 201 facing the electromagnetic radiation monitoring instrument 103, and the other end is fixedly connected to the exhaust end of the exhaust pump 205. One end of the air inlet pipe 204 is fixedly connected to the upper side of the drying box 201 facing the electromagnetic radiation monitoring instrument 103, and the other end is fixedly connected to the upper side of the electromagnetic radiation monitoring instrument 103. The exhaust pump 205 is fixedly connected to the support rod 102, and the air inlet end of the exhaust pump 205 is fixedly connected to the lower side of the electromagnetic radiation monitoring instrument 103. The outer cover of the exhaust pump 205 is provided with an electromagnetic shielding cover, which is fixedly connected to the support rod 102. By setting the electromagnetic shielding cover, a certain shielding effect can be played, thereby reducing the influence of the electromagnetic radiation generated by the exhaust pump 205 on the detection value of the electromagnetic radiation monitoring instrument 103, thereby ensuring the accuracy of the detection of the electromagnetic radiation monitoring instrument 103.

[0024] When drying the moisture inside the electromagnetic radiation monitoring instrument 103, start the vacuum pump 205. When the vacuum pump 205 runs, the moisture inside the electromagnetic radiation monitoring instrument 103 enters the desiccant box 206 inside the drying box 201 through the vacuum pipe 203. After being dried by the multi-layer desiccant box 206, it enters the electromagnetic radiation monitoring instrument 103 through the air inlet pipe 204, thereby ensuring that the air inside the electromagnetic radiation monitoring instrument 103 is in a dry state, and thus it is not easy to cause a short circuit in the electromagnetic radiation monitoring instrument 103.

[0025] Drying unit 200, such as Figure 2The drying unit 200 includes a drying box 201 fixed to the rear side of the support rod 102 , a plurality of desiccant boxes 206 sealed and slidably connected to the interior of the drying box 201 , and an exhaust assembly connected to the drying box 201 .

[0026] Replace the spare unit 300, such as Figure 2 The replacement spare unit 300 is located directly above the drying box 201 and is fixedly connected to the support rod 102 for storing the spare desiccant box 206 .

[0027] Replace the starter unit 500, such as Figure 2 The replacement start unit 500 is symmetrically arranged on the left and right sides of the drying box 201. The replacement start unit 500 is connected to the support rod 102, the replacement standby unit 300, and the saturated storage unit 400, and is used to replace the desiccant box 206 at the bottom of the drying box 201.

[0028] Specifically, Figure 4 The desiccant box 206 is filled with desiccant. A plurality of vent holes 207 are evenly provided on the upper and lower sides of the desiccant box 206 for gas circulation. An air inlet and outlet hole 208 is provided on one side of the desiccant box 206. The air inlet and outlet holes 208 on the desiccant box 206 at the bottom of the drying box 201 are arranged correspondingly to one end of the exhaust pipe 203, and the air inlet and outlet holes 208 on the desiccant box 206 at the top of the drying box 201 are arranged correspondingly to one end of the air inlet pipe 204. The advantage of such an arrangement is that the desiccant box 206 at the bottom is in contact with moisture first, and can reach a saturated state earlier than the desiccant box 206 at the top. When the desiccant box 206 is replaced later, one or two desiccant boxes 206 at the bottom of the drying box 201 can be replaced each time, thereby further extending the working cycle of the maintenance personnel. The air inlet and outlet holes 208 on the desiccant box 206 at the top of the drying box 201 are arranged correspondingly to one end of the air inlet pipe 204.

[0029] Specifically, Figure 5 The replacement spare unit 300 includes a spare storage box 301 located directly above the drying box 201, the spare storage box 301 is fixedly connected to the support rod 102 by a first fixing rod, the spare storage box 301 is a top-to-bottom communicating structure, the desiccant box 206 is stacked in the spare storage box 301 and is sealed and slidably connected to the inside of the spare storage box 301, and a first cover plate 302 is sealed and fixed to the top of the spare storage box 301 by screws. The purpose of this arrangement is to facilitate disassembly and assembly, and to facilitate the subsequent maintenance personnel to add the desiccant box 206. Insertion grooves 303 are provided on both sides of the spare storage box 301, and the insertion grooves 303 correspond to the gap between the two lowest desiccant boxes 206 in the spare storage box 301.

[0030] Specifically, Figure 6, The replacement starting unit 500 includes a support plate 501 fixedly connected to the support rod 102. On the side of the support plate 501 away from the drying box 201, a driving motor 502 is fixedly installed by bolts. An electromagnetic shielding cover is adaptively provided outside the driving motor 502. By setting the electromagnetic shielding cover, a certain shielding effect can be achieved, reducing the influence of the electromagnetic radiation generated by the operation of the driving motor 502 on the detection value of the electromagnetic radiation monitoring instrument 103, and ensuring the accuracy of the detection by the electromagnetic radiation monitoring instrument 103. The output end of the driving motor 502 passes through the support plate 501 and is fixedly connected to a first lead screw 503. A moving block 504 is threadedly connected to the first lead screw 503. A C-shaped plate 505 is fixedly connected to the moving block 504. The top of the open side of the C-shaped plate 505 is fixedly connected to a first sealing plate 506. The upper and lower sides of the first sealing plate 506 are respectively in sealed sliding connection with the bottom end of the spare storage box 301 and the top end of the drying box 201, for sealing the bottom end of the spare storage box 301 and the top end of the drying box 201. The advantage of such a setting is that moisture in the outside air is not easily introduced into the spare storage box 301 and the drying box 201, thereby being able to extend the service life of the desiccant box 206. The bottom of the open side of the C-shaped plate 505 is fixedly connected to a second sealing plate 507. The upper side of the second sealing plate 507 is in sealed sliding connection with the bottom end of the drying box 201, for sealing the bottom end of the drying box 201 to prevent moisture in the outside air from entering the drying box 201.

[0031] As Figure 8-9 , on the side of the second sealing plate 507 away from the C-shaped plate 505, a storage groove 508 is opened. A telescopic component 509 is connected in the storage groove 508. The top of the side of the second sealing plate 507 facing the C-shaped plate 505 is fixedly connected to a limiting component 510. A limiting release rod 511 is fixedly connected to the support plate 501 at the position corresponding to the limiting component 510. One end of the limiting release rod 511 facing the limiting component 510 is provided with a first inclined surface 512 that slopes downward; As Figure 7 , at the position corresponding to the first guiding sliding sleeve 202 on the C-shaped plate 505, a separating component 513 is fixedly connected. The separating component 513 is slidably fitted with the first guiding sliding sleeve 202, and the inner end of the separating component 513 supports on the bottom of the second-to-last desiccant box 206 in the drying box 201; As Figure 7 , a small gear 514 is fixedly sleeved on the first lead screw 503. An inserting component 515 is connected to the top of the small gear 514. The inserting component 515 is connected to the top of the support plate 501 and the insertion slot 303.

[0032] Furthermore, as Fig.10The telescopic assembly 509 includes a telescopic plate 509-1 adapted to slide with the inside of the storage groove 508. The upper surface of the telescopic plate 509-1 is flush with the upper surface of the second sealing plate 507. The advantage of such a setting is that it does not affect the sealing effect of the second sealing plate 507, and can prevent the desiccant box 206 in the drying box 201 from protruding out of the drying box 201 when the desiccant box 206 moves downward as a whole, thereby not easily hindering the later reset of the second sealing plate 507. A moving rod 509-2 is fixedly connected to one end of the telescopic plate 509-1, and a vertical rod 509-3 is fixedly connected to the top of the end of the moving rod 509-2 away from the telescopic plate 509-1. A first spring 509-4 is fixedly connected between the telescopic plate 509-1 and the inner wall of the storage groove 508, and the first spring 509-4 is arranged parallel to the moving rod 509-2.

[0033] like Fig. 9 A moving groove 516 is provided at the top of the second sealing plate 507 near the limiting assembly 510. The moving groove 516 is connected to the receiving groove 508 through a through groove. The moving rod 509-2 slides through the through groove. The top of the vertical rod 509-3 protrudes out of the moving groove 516, and the top of the vertical rod 509-3 is an arc-shaped structure. like Fig.11 The limiting assembly 510 includes an L-shaped plate 510-1 fixedly connected to the top of the second sealing plate 507, the L-shaped plate 510-1 is inverted, and the top of the L-shaped plate 510-1 is slidably penetrated by an abutting rod 510-2, the bottom end of the abutting rod 510-2 is an arc-shaped structure, and the arc-shaped bottom end of the abutting rod 510-2 is movably abutted with the arc-shaped top end of the vertical rod 509-3 toward the side of the drying box 201, and the purpose of such a setting is that when the vertical rod 509-3 is strongly pushed, the arc-shaped structure can be used to cooperate with the abutting rod. When abutting, the first spring 509-4 is in a compressed state, that is, the rebound force of the first spring 509-4 is less than the elastic force of the second spring 510-4, so that the limiting state of the abutting rod 510-2 to the vertical rod 509-3 can be maintained. The top of the abutment rod 510-2 is fixedly connected to a lifting rod 510-3, and a second spring 510-4 is fixedly connected between the lifting rod 510-3 and the top of the L-shaped plate 510-1. The second spring 510-4 is movably sleeved on the outside of the abutment rod 510-2. The end of the lifting rod 510-3 facing the first inclined surface 512 is an arc structure and is arranged corresponding to the first inclined surface 512. The purpose of this arrangement is that when the lifting rod 510-3 moves toward the first inclined surface 512, under the action of the first inclined surface 512, the lifting rod 510-3 can move upward (such as Fig.16 ), the lifting rod 510-3 stretches the second spring 510-4, and the abutment rod 510-2 moves upward following the lifting rod 510-3. When the abutment rod 510-2 is completely separated from the vertical rod 509-3, the vertical rod 509-3 can move toward the drying box 201 under the action of the rebound force of the first spring 509-4.

[0034] Specifically, Fig.12 The partition assembly 513 includes a partition plate 513-1 that is sealed and slidably connected to the first guide sleeve 202. The partition plate 513-1 is sealed and slidably connected to the first guide sleeve 202. On the one hand, it can seal the interior of the drying box 201, and on the other hand, it can enable the partition plate 513-1 to move smoothly. The inner end of the partition plate 513-1 is supported on the bottom of the penultimate desiccant box 206 in the drying box 201. A small-diameter hole 513-2 is provided on the outer end of the partition plate 513-1. A large-diameter hole 513-3 that is connected to the small-diameter hole 513-2 is provided inside the partition plate 513-1. A T-shaped rod 513-4 is adapted and slidably connected in the large-diameter hole 513-3 and the small-diameter hole 513-2. The outer end of the T-shaped rod 513-4 is fixedly connected to the t-shaped plate 505. The inner end of the partition plate 513-1 is set as a second inclined surface that is inclined downward, and the lower end of the second inclined surface is adjacent to the drying box. The purpose of this arrangement is, on the one hand, to facilitate the insertion of the partition plate 513-1 into the gap between two adjacent desiccant boxes 206, and on the other hand, during the insertion process, no squeezing force is generated on the desiccant box 206 located at the bottom of the partition plate 513-1, but squeezing force is generated on the desiccant box 206 above the partition plate 513-1, because the desiccant box 206 at the bottom of the partition plate 513-1 has no space to move, while the desiccant box 206 located above the partition plate 513-1 has space to move.

[0035] When the partition plate 513-1 is supported on the bottom of the desiccant box 206, the large diameter section of the T-bar 513-4 is in movable contact with one end of the large diameter hole 513-3 close to the drying box 201. When in contact here, when the T-bar 513-4 moves, the partition plate 513-1 will not move with the T-bar 513-4. When the partition plate 513-1 starts to move, the large diameter section of the T-bar 513-4 is in movable contact with the other end of the large diameter hole 513-3, so that the partition plate 513-1 can be pulled out from the bottom of the desiccant box 206.

[0036] Furthermore, Fig.13The insertion component 515 includes a fixed plate 515-1 fixedly connected to the top of the bracket plate 501, and a second screw rod 515-2 is rotatably installed on the fixed plate 515-1 through a bearing. A large gear 515-3 is fixedly sleeved on the second screw rod 515-2, and the large gear 515-3 is meshingly connected with the small gear 514. The purpose of the meshing connection is that when the small gear 514 rotates, it can drive the large gear 515-3 to rotate. An insertion rod 515-4 is threadedly sleeved on one end of the second screw rod 515-2 away from the fixed plate 515-1, and a second guide sleeve 515-5 is fixedly connected to the upper and lower sides of the insertion rod 515-4. A guide slide rod 515-6 slides through the second guide sleeve 515-5, and one end of the guide slide rod 515-6 is fixedly connected to the outer wall of the spare storage box 301. Through the coordinated use of the guide slide rod 515-6 and the second guide sleeve 515-5, when the second screw rod 515-2 rotates, the insertion rod 515-4 can be moved along the rotation of the second screw rod 515-2. The insertion rod 515-4 is sealingly and slidingly connected with the insertion groove 303. When sealingly and slidingly connected, the insertion groove 303 can be sealed, so that moisture in the outside air is not easy to enter the spare storage box 301; the end of the insertion rod 515-4 away from the fixed plate 515-1 is set as a tip structure, and the tip structure is a downward inclined slope, and the tip corresponds to the gap between the two lowest desiccant boxes 206 in the spare storage box 301. The purpose of this setting is to facilitate the insertion of the insertion rod 515-4 into the gap. Example 2

[0037] Reference Fig.17 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the device also includes a saturated storage unit 400, which is located directly below the drying box 201 and is fixedly connected to the support rod 102, and is used to store the replaced desiccant box 206 so that the desiccant box 206 can be reused.

[0038] Specifically, the saturated storage unit 400 includes a used desiccant box storage box 401 located directly below the drying box 201, and the lower side of the second sealing plate 507 is sealingly slidably connected to the top of the used desiccant box storage box 401, and is used to seal the top of the used desiccant box storage box 401. The used desiccant box storage box 401 is fixedly connected to the support rod 102 via a second fixing rod. The used desiccant box storage box 401 is a top-to-bottom connecting structure, and the bottom end of the used desiccant box storage box 401 is sealed and fixedly connected to the second cover plate 402 via screws, which is convenient for disassembly and assembly, thereby facilitating maintenance personnel to take out the saturated desiccant box 206 in the used desiccant box storage box 401, so as to dry the desiccant box 206 for secondary use, thereby saving resources.

[0039] The remaining structures are the same as those of Example 1.

[0040] The monitoring method using the electromagnetic environment monitoring device for a high-voltage power transmission and transformation project as described above is as follows: Step 1: When drying the inside of the electromagnetic radiation monitoring instrument 103, start the air pump 205. The air pump 205 operates to draw the moisture inside the electromagnetic radiation monitoring instrument 103 into the drying box 201. The moisture is first dried by the desiccant box 206 at the bottom of the drying box 201, and then successively dried by the stacked desiccant boxes 206 above. Finally, it enters the intake pipe 204 through the air inlet and outlet hole 208 on one side of the desiccant box 206 at the top of the drying box 201, and then the dried gas is introduced into the electromagnetic radiation monitoring instrument 103 to complete the drying, which is not likely to cause a short-circuit phenomenon in the electromagnetic radiation monitoring instrument 103.

[0041] Step 2: After using it for a period of time, when the desiccant box 206 at the bottom of the drying box 201 needs to be discharged from the drying box 201, start the driving motor 502. The output end of the driving motor 502 drives the first lead screw 503 to rotate. The first lead screw 503 drives the small gear 514 to rotate. The moving block 504 moves along the first lead screw 503 away from the drying box 201 under the limiting action of the U-shaped plate 505, the first sealing plate 506, and the second sealing plate 507. The moving block 504 drives the U-shaped plate 505 to move accordingly. The U-shaped plate 505 drives the first sealing plate 506, the second sealing plate 507, and the T-shaped rod 513-4 to move. When the first sealing plate 506 and the second sealing plate 507 are gradually opened and the openings at the upper and lower ends of the drying box 201 are all exposed (as Fig.15 )), the desiccant box 206 at the bottom of the drying box 201 falls into the used desiccant box storage box 401 under its own gravity, while the second-to-last desiccant box 206 in the drying box 201 is supported by the partition plate 513-1 and will not fall into the used desiccant box storage box 401; Step 3: During the process of opening the upper and lower ends of the drying box 201, the large diameter section of the T-shaped rod 513-4 slides in the large diameter hole 513-3. When the large diameter section of the T-shaped rod 513-4 contacts the end of the large diameter hole 513-3 away from the drying box 201, the upper and lower ends of the drying box 201 open. When the driving motor 502 continues to drive the shaped plate 505 to move, the shaped plate 505 continues to drive the first sealing plate 506, the second sealing plate 507, and the T-shaped rod 513-4 to follow the movement. The T-shaped rod 513-4 pulls the partition plate 513-1 to move outward by contacting the end of the large diameter hole 513-3 away from the drying box 201. As the partition plate 513-1 moves outward step by step, the lifting rod 510-3 first contacts the first inclined surface 512 at one end of the limit release rod 511. After the contact, when the lifting rod 510-3 continues to move, the lifting rod 510-3 pulls the abutment rod 510-2 to move upward under the action of the first inclined surface 512. When the abutment rod 510-2 is separated from the vertical rod 509-3, the vertical rod 509-3 moves toward the drying box 201 under the action of the rebound force of the first spring 509-4. The telescopic plate 509-1 also passes through the storage groove 508 under the action of the rebound force of the first spring 509-4 and intersects with the bottom opening of the drying box 201 (such as Fig.16 ), used to prevent the desiccant box 206 from falling again. At this time, the partition plate 513-1 has not completely separated from the bottom of the penultimate desiccant box 206. Then, the partition plate 513-1 is driven to retreat by the driving motor 502. When the partition plate 513-1 is completely separated from the bottom of the penultimate desiccant box 206, the desiccant box 206 in the drying box 201 moves downward as a whole. The limiting effect of the telescopic plate 509-1 prevents the desiccant box 206 in the drying box 201 from falling out of the drying box 201 when the desiccant box 206 in the drying box 201 moves downward as a whole. Step 4: In addition, during the process of opening the upper and lower ends of the drying box 201, the small gear 514 rotates and drives the large gear 515-3 meshing therewith to rotate. The large gear 515-3 drives the second screw rod 515-2 to rotate in the opposite direction to the first screw rod 503, so that the insertion rod 515-4 moves in the opposite direction to the first sealing plate 506. During the step-by-step opening of the first sealing plate 506, the insertion rod 515-4 is inserted into the gap between the two lowest desiccant boxes 206 in the spare storage box 301 through the action of the tip, so as to limit the second to last desiccant box 206 in the spare storage box 301. When the bottom end of the spare storage box 301 and the top end of the drying box 201 are fully opened, the lowest desiccant box 206 in the spare storage box 301 falls into the drying box 201 under the action of its own gravity (such as Fig.16 ), thereby achieving the purpose of automatically replenishing the desiccant box 206 in the drying box 201; Step Five: When the first sealing plate 506 and the second sealing plate 507 are closed again, the driving motor 502 drives the first lead screw 503 to rotate in the opposite direction to before, so that the moving block 504 drives the U-shaped plate 505 to move towards the drying box 201. The U-shaped plate 505 drives the first sealing plate 506, the second sealing plate 507, and the T-shaped rod 513-4 to move along. When the large-diameter section of the T-shaped rod 513-4 contacts the end of the large-diameter hole 513-3 close to the drying box 201, the separating plate 513-1 is driven by the contact force to be inserted into the drying box 201 again and supported at the bottom of the penultimate desiccant box 206. The first sealing plates 506 on both sides block between the spare storage box 301 and the drying box 201. During the process of the second sealing plates 507 on both sides approaching each other, due to the extrusion force, the telescopic plate 509-1 is squeezed into the receiving groove 508. The telescopic plate 509-1 drives the vertical rod 509-3 to move away from the drying box 201 through the moving rod 509-2, and through the cooperation of the arc structure at the top of the vertical rod 509-3 and the arc structure at the bottom of the abutting rod 510-2, the abutting rod 510-2 moves upward. When the vertical rod 509-3 passes through the abutting rod 510-2, the abutting rod 510-2 moves downward and resets under the resilience of the second spring 510-4, and limits the vertical rod 509-3. During the process of the insertion rods 515-4 gradually closing the first sealing plates 506 on both sides, they are gradually withdrawn from the bottom of the lowermost desiccant box 206 in the spare storage box 301. When they are completely separated from the desiccant box 206, all the desiccant boxes 206 in the spare storage box 301 move downward as a whole, waiting to replenish the desiccant box 206 into the drying box 201 next time. The above overall operation is simple and can automatically replace the saturated desiccant boxes step by step. It only requires manual intervention for replenishment and maintenance when all the desiccant boxes 206 in the spare storage box 301 are used up. This process has a long cycle and can significantly reduce the workload of maintenance personnel.

[0042] It should be noted that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, the electrical connection relationship and the specific circuit structure are not described in detail here.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.

10. The monitoring method of the electromagnetic environment monitoring device for high-voltage power transmission and transformation engineering according to claim 1, characterized in that: The following steps are involved: Step 1: When drying the interior of the electromagnetic radiation monitoring instrument (103), the vacuum pump (205) is started, and the vacuum pump (205) is operated to draw moisture inside the electromagnetic radiation monitoring instrument (103) into the drying box (201). The moisture is first dried by the bottom desiccant box (206) in the drying box (201), and then dried in turn by the desiccant boxes (206) stacked above. Finally, the moisture enters the air inlet pipe (204) through the air inlet and outlet holes (208) on one side of the top desiccant box (206) in the drying box (201), and then the dried gas is introduced into the electromagnetic radiation monitoring instrument (103) to complete the drying; Step 2: After using for a period of time, when it is necessary to discharge the desiccant box (206) at the bottom of the drying box (201) from the drying box (201), start the driving motor (502). The output end of the driving motor (502) drives the first lead screw (503) to rotate. The first lead screw (503) drives the small gear (514) to rotate. Under the limiting action of the C-shaped plate (505), the first sealing plate (506), and the second sealing plate (507), the moving block (504) moves along the first lead screw (503) in a direction away from the drying box (201). The moving block (504) drives the C-shaped plate (505) to move accordingly. The C-shaped plate (505) drives the first sealing plate (506), the second sealing plate (507), and the T-shaped rod (513-4) to move. When the first sealing plate (506) and the second sealing plate (507) are gradually opened and the openings at the upper and lower ends of the drying box (201) are all exposed, the desiccant box (206) at the bottom of the drying box (201) falls into the used desiccant box storage box (401) under its own gravity. However, the second-to-last desiccant box (206) in the drying box (201) is supported by the partition plate (513-1) and will not fall into the used desiccant box storage box (401). Step 3: During the process of opening the upper and lower openings of the drying box (201), the large diameter section of the T-shaped rod (513-4) slides in the large diameter hole (513-3). When the large diameter section of the T-shaped rod (513-4) contacts the end of the large diameter hole (513-3) away from the drying box (201), the upper and lower openings of the drying box (201) are opened. When the driving motor (502) continues to drive the shaped plate (505) to move, the shaped plate (505) continues to drive the first sealing plate (506) and the second sealing plate (507). , the T-shaped rod (513-4) moves with it, and the T-shaped rod (513-4) pulls the partition plate (513-1) to move outward by contacting the end of the large-diameter hole (513-3) away from the drying box (201). During the process of the partition plate (513-1) moving outward step by step, the lifting rod (510-3) first contacts the first inclined surface (512) at one end of the limit release rod (511). After the contact, when the lifting rod (510-3) continues to move, the lifting rod (510-3) is moved under the action of the first inclined surface (512). -3) pulls the abutting rod (510-2) to move upward. When the abutting rod (510-2) is separated from the vertical rod (509-3), the vertical rod (509-3) moves toward the drying box (201) under the action of the rebound force of the first spring (509-4). The telescopic plate (509-1) also passes through the storage groove (508) under the action of the rebound force of the first spring (509-4) and intersects with the bottom opening of the drying box (201) to prevent the desiccant box (206) from falling again. At this time, the partition plate (513- 1) before completely detaching from the bottom of the penultimate desiccant box (206), the partition plate (513-1) is driven to move backwards by the driving motor (502). When the partition plate (513-1) completely detaches from the bottom of the penultimate desiccant box (206), the desiccant box (206) in the drying box (201) moves downward as a whole. The limiting effect of the telescopic plate (509-1) prevents the desiccant box (206) in the drying box (201) from falling out of the drying box (201) when the desiccant box (206) in the drying box (201) moves downward as a whole. Step 4: In addition, during the process of opening the upper and lower ends of the drying box (201), the small gear (514) rotates and drives the large gear (515-3) meshing therewith to rotate. The large gear (515-3) drives the second screw rod (515-2) to rotate in the opposite direction to the first screw rod (503), so that the movement direction of the insertion rod (515-4) and the first sealing plate (506) are opposite. During the process of gradually opening the first sealing plate (506), the insertion rod (515-4) is inserted into the first sealing plate (506) through the action of the tip. The desiccant box (206) is inserted into the gap between the two lowest desiccant boxes (206) in the spare storage box (301) to limit the position of the second to last desiccant box (206) in the spare storage box (301); when the bottom of the spare storage box (301) and the top of the drying box (201) are fully opened, the lowest desiccant box (206) in the spare storage box (301) falls into the drying box (201) under the action of its own gravity, thereby achieving the purpose of automatically replenishing the desiccant box (206) in the drying box (201); Step 5: When the first sealing plate (506) and the second sealing plate (507) are closed again, the first screw rod (503) is driven by the driving motor (502) to rotate in the opposite direction to the previous direction, so that the moving block (504) drives the shaped plate (505) to move toward the drying box (201), and the shaped plate (505) drives the first sealing plate (506), the second sealing plate (507), and the T-shaped rod (513-4) to move accordingly. When the large warp section of the T-shaped rod (513-4) is aligned with the When the large diameter hole (513-3) is close to one end of the drying box (201), the contact force drives the partition plate (513-1) to be inserted into the drying box (201) again and supported on the bottom of the penultimate desiccant box (206), and the first sealing plates (506) on both sides are blocked between the spare storage box (301) and the drying box (201). In the process of the second sealing plates (507) on both sides approaching each other, the extrusion force squeezes the telescopic plate (509-1) into the storage groove (5 08), the telescopic plate (509-1) drives the vertical rod (509-3) to move in a direction away from the drying box (201) through the moving rod (509-2), and the arc structure at the top of the vertical rod (509-3) cooperates with the arc structure at the bottom of the abutting rod (510-2), so that the abutting rod (510-2) moves upward. When the vertical rod (509-3) passes through the abutting rod (510-2), the abutting rod (510-2) is resilient under the rebound force of the second spring (510-4). The insertion rod (515-4) is gradually pulled out from the bottom of the lowest desiccant box (206) in the spare storage box (301) during the gradual closing of the first sealing plates (506) on both sides, and when the insertion rod (515-4) is completely separated from the desiccant box (206), all the desiccant boxes (206) in the spare storage box (301) move downward as a whole, waiting for the next replenishment of the desiccant box (206) into the drying box (201).
