DETAILED DESCRIPTION
[0059] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0060] Reference Figure 3 -Attached Fig. 9 , an intelligent inspection device, comprising:
[0061] Ditch 1;
[0062] A plurality of cover plates 2 are covered on the ditch 1 to form a closed space inside the ditch 1;
[0063] Two rows of mounting frames 3 are fixedly mounted on both sides of the ditch 1 by bolt fastening, and are used to arrange and support the cables located in the ditch 1;
[0064] A plurality of water absorbing components are fixedly arranged inside the ditch 1, and the bottoms thereof are in contact with the bottom of the ditch 1, so as to absorb the accumulated water formed at the bottom of the ditch 1 in time;
[0065] A pressure sensing component is arranged inside the water absorbing component to sense the weight of the water absorbing component in real time;
[0066] A drainage pipe 4, one end of which is connected to the bottom of the ditch 1, and a water pump 5 is provided at the other end;
[0067] The critical value of the gravity sensing of the water absorbing component by the pressure sensing component is preset to convert the amount of water accumulated in the ditch 1 into the weight of the water absorbing component. When the monitoring exceeds the critical value, the water pump 5 is started to suck and discharge the water accumulated at the bottom of the ditch 1.
[0068] A baffle plate 6 is fixed between two adjacent water absorbing components, and inclined blocks 7 are fixed on both sides of the baffle plate 6. The inclined blocks 7 on both sides of the water absorbing components make the accumulated water concentrate near the water absorbing components.
[0069] The water-absorbing parts include:
[0070] Sponge blocks;
[0071] Two vertical plates 8, respectively located on both sides of the sponge block;
[0072] The sponge block and the vertical plate 8 are both provided with a space allowing the cable to pass through, and the sponge block and the vertical plate 8 are both provided with a central groove 9, and the pressure sensing component is arranged inside the central groove 9 of the sponge block;
[0073] Pressure sensing components include:
[0074] The fixing portion 10 is fixed at a fixed height inside the central groove 9 of the sponge block;
[0075] A covering portion 11, covering the fixing portion 10 and being slidably connected to the fixing portion 10;
[0076] The pressure sensor 12 is arranged between the fixing portion 10 and the covering portion 11;
[0077] The higher the water absorption of the sponge block, the heavier the weight of the sponge block itself, and the sponge block will press the covering part 11 downward to make the inner top surface of the covering part 11 closer to the top surface of the fixing part 10, and the higher the sensing value of the pressure sensor 12 will be.
[0078] A parallel plate 13 is fixedly connected between two adjacent baffles 6. The parallel plate 13 passes through the vertical plate 8 and the central groove 9 of the sponge block. The fixing part 10 is fixed on the parallel plate 13. The parallel plate 13 is fixedly connected to a sealing box 14. A hydraulic cylinder 15 is installed inside the sealing box 14. The output shaft of the hydraulic cylinder 15 extends outward through the sealing box 14 and fixes a resistance block 16. The resistance block 16 is fixedly connected to the vertical plate 8 on one side of the sponge block, and the vertical plate 8 on the other side of the sponge block is fixedly connected to the ditch 1. When the sensing value of the pressure sensor 12 exceeds the critical value, the hydraulic cylinder 15 is started and the force is transmitted through the vertical plate 8 on one side to squeeze the sponge block, so that the accumulated water absorbed by the sponge block is squeezed out to the bottom of the ditch 1 again.
[0079] The sponge block is divided into an upper block 17 and a lower block 18, and the upper block 17 and the lower block 18 are assembled into a whole sponge block. The upper block 17 and the lower block 18 are integrally extended to set a wrapping portion 19, and the wrapping portions 19 of the upper block 17 and the lower block 18 can completely wrap the surface of the cable between two adjacent water-absorbing components. From a practical point of view, the wrapping portions 19 of the upper block 17 and the lower block 18 will be overlong. When wrapping, the portion exceeding the cable length will be subtracted accordingly, so that the cable surface can be completely wrapped, avoiding the phenomenon of incomplete wrapping due to insufficient length of the wrapping portion 19, and the cable surface is completely wrapped. When condensation occurs on the cable surface in the cable trench, the sponge block can quickly absorb the small dewdrops formed by the condensation, avoiding the cable from being damp for a long time, and also reducing the unnecessary weight of the cable and water droplets caused by condensation.
[0080] A rectangular groove 20 with multiple grooves is opened at the bottom of the ditch 1, and the rectangular groove 20 is located between two adjacent baffles 6. The bottom of the lower block 18 extends toward the rectangular groove 20 to form an extension portion 21. The extension portion 21 of the lower block 18 is located inside the rectangular groove 20. The opening of the baffle 6 separates the accumulated water in the ditch 1. The opening of the rectangular groove 20 facilitates the accumulated water in the ditch 1 to fall into it, and the extension portion 21 of the lower block 18 facilitates the rapid absorption of the accumulated water falling into the rectangular groove 20.
[0081] It should be noted that:
[0082] The drainage pipe 4 has multiple branches, one end of which extends into the corresponding rectangular groove 20, and the other end is connected to each branch pipe to form a main pipe. The main pipe extends out of the ground and is connected to the water pump 5. When the water pump 5 is started, each branch pipe synchronously absorbs the accumulated water in each rectangular groove 20.
[0083] Inspection method:
[0084] The sponge block absorbs the accumulated water in the ditch 1 and simultaneously absorbs the condensation formed on the cable. The absorbed water is retained on the sponge block. The accumulated water in the ditch 1 is absorbed by the sponge block and converted into the weight of the sponge block.
[0085] The increased downward pressure of the sponge block is sensed by the pressure sensitive element of the pressure sensor 12 and the pressure information is sent by the signal processing unit. When the pressure value in the pressure information exceeds a preset critical value, the hydraulic cylinder 15 is turned on to squeeze the sponge block to discharge the absorbed water, and the water pump 5 is turned on to suck and discharge the accumulated water in the ditch 1.
[0086] Reference Figure 1 , Attachment Figure 2 The power operation and maintenance management system contains inspection equipment with monitoring functions, an operation and maintenance terminal that receives monitoring signals sent by the inspection equipment, and a distribution server containing a distribution database. The specific execution steps are as follows:
[0087] S10, the inspection equipment is located inside the cable trench, absorbs the accumulated water inside the cable trench and the condensation formed on the cable synchronously, converts the accumulated water content into weight, and each pressure sensor 12 in the inspection equipment sends the weight change to the operation and maintenance end in real time;
[0088] S11, each pressure sensor 12 synchronously and in real time sends pressure information to the operation and maintenance end, wherein the time interval between two pressure information sent by the same pressure sensor 12 received by the operation and maintenance end is 1min-3min;
[0089] S12, judging the pressure information received each time according to a preset critical value, wherein the pressure information contains a specific pressure value;
[0090] S13, if any pressure value exceeds the critical value, the operation of fully draining the accumulated water will be automatically executed; if it does not exceed the critical value, S11 will continue to be executed;
[0091] The operation of fully draining the accumulated water is as follows: synchronously start the hydraulic cylinders 15 to drive the vertical plates 8 to squeeze the sponge blocks, and the accumulated water is squeezed out and sucked by the water pump 5 to be discharged from the drainage pipes 4 for treatment.
[0092] For the following scenarios:
[0093] In some areas, the cable trench is not only used for distributing cables, but also for sharing with water pipes. If a water pipe breaks somewhere, it will also cause the water in the trench 1 to increase rapidly. If a cover plate 2 on the trench 1 breaks, it will also easily cause the water in the trench 1 to increase rapidly on rainy days. The specific solutions are as follows:
[0094] S20, setting the pressure information before the automatic full water drainage operation as the first pressure information, setting the pressure information after the automatic full water drainage operation as the second pressure information, and the interval between the first pressure information and the second pressure information is 1min-3min;
[0095] S21, each pressure sensor 12 synchronously and in real time sends the first pressure information to the operation and maintenance end;
[0096] S22, judging the first pressure information received each time according to a preset critical value, wherein the first pressure information contains a specific pressure value;
[0097] S23, if the pressure value of any item of the first pressure information exceeds the critical value, the operation of fully draining the accumulated water is automatically executed; if it does not exceed the critical value, S21 is continued to be executed;
[0098] S24, the operation and maintenance end sends a first position request instruction to the distribution server, wherein the first position request instruction is a request to send the position of the pressure sensor 12 whose pressure value exceeds the critical value;
[0099] S25, the distribution server receives a first position request instruction, wherein the first position request instruction contains n first pressure information, n is a positive integer greater than 0, the distribution server establishes a distribution database, the distribution database contains an identifier of each pressure sensor 12, after obtaining the n first pressure information, the distribution server analyzes the first pressure information and compares it with the identifier of each pressure sensor 12 in the distribution database, determines the position of the pressure sensor 12 that sends the first pressure information exceeding the critical value, obtains n first position information, and sends the n first position information to the operation and maintenance end;
[0100] S26, after the operation of automatically running the full drainage of the accumulated water, each pressure sensor 12 continues to synchronously and in real time send the second pressure information to the operation and maintenance end;
[0101] S27, if none of them reaches the critical value, the second pressure information is changed to the first pressure information, and S21 is continued to be executed. If the pressure value of any item of the second pressure information exceeds the critical value, the operation and maintenance end sends a second position request instruction to the distribution server to determine whether the pressure value exceeding the critical value this time is sent from the same pressure sensor 12 as the pressure value exceeding the critical value last time;
[0102] S28, the distribution server receives a second position request instruction, wherein the second position request instruction contains each second pressure information exceeding the critical value. After obtaining the second pressure information, the distribution server analyzes the second pressure information and compares it with the identifier of each pressure sensor 12 in the distribution database, determines the position of the pressure sensor 12 that sends the pressure information, obtains the second position information, and sends the second position information to the operation and maintenance end;
[0103] S29, the operation and maintenance end compares the n first location information and the n second location information obtained respectively before and after in sequence to determine whether the same location appears twice;
[0104] S210, if not, then start the automatic operation to fully drain the accumulated water, and continue to execute S21, if yes, then start the automatic operation to fully drain the accumulated water and the maintenance personnel will send the location information of the emergency repair.
[0105] In summary, when the operation and maintenance end obtains the position of the pressure sensor 12 with an abnormal pressure value, it can send a rescue signal to the operation and maintenance personnel and accurately locate the specific abnormal position in the cable trench, facilitating rapid repair and rescue.
[0106] In addition, after the operation and maintenance end obtains the abnormal pressure value, it sends the cable trench abnormal warning information to the mobile terminal of each user, so that the user can know the cause of the power outage in time, which can avoid the user making multiple calls in a short period of time without knowing it, thereby squeezing out administrative resources.
[0107] Similarly, you can obtain various pressure information through the operation and maintenance end to judge and compare:
[0108] For example, if it is found that after the pressure information sent by an individual pressure sensor 12 exceeds the critical value and has undergone drainage processing, the pressure value it feedbacks does not decrease or instead continues to increase, it can be determined that the vertical plate 8 on the sponge block side of the pressure sensor 12 is not squeezed, and the hydraulic cylinder 15 at this position fails, and an emergency repair signal can be sent to the maintenance personnel.
