Description

Technical Field

[0001] The present invention relates to the technical field of instrument cabinets, and in particular to an electrical automation instrument cabinet with an online monitoring and early warning function. Background Art

[0002] The electrical automation instrument cabinet is an integrated instrument with measurement, control, early warning and other functions. It is also a cabinet for centralized arrangement and installation of automation instruments. Its main function is to protect components and avoid damage and errors due to external interference.

[0003] To facilitate unified observation and operational control, various electrical instruments are usually integrated into an electrical automation instrument cabinet. Therefore, the cabinet generates a lot of heat during operation. If the heat cannot be dissipated in time, it will directly affect the normal use of various electrical instruments. A Chinese patent (Announcement No.: CN205882447U) discloses a new type of electrical instrument cabinet. The cabinet is equipped with a fan to speed up the air flow in the cabinet, so that the high-temperature gas is discharged through the heat dissipation holes to avoid excessive temperature inside the cabinet. In addition, a filter is provided inside the heat dissipation holes to prevent dust from entering the instrument and preventing dust from damaging the service life of the instrument. However, the above structural settings and contents still have the following problems in actual use:

[0004] 1. When the electrical automation instrument cabinet is outdoors and encounters rain, rainwater splashes into the interior through the heat dissipation holes. However, the existing technology cannot block and evacuate the rainwater in time, which can easily affect and interfere with the internal electrical components of the electrical automation instrument cabinet.

[0005] 2. During the long-term process of blocking dust, a large amount of dust and impurities will adhere to the side of the filter exposed on the outside of the cabinet, and even clog the filter holes, resulting in a decrease in the ventilation effect of the filter. However, in the existing technology, it is impossible to monitor the clogging status of the filter in real time and issue an early warning, and it is difficult to clean the filter in time according to the clogging status. This can easily lead to abnormalities and failures of the electrical components inside the electrical automation instrument cabinet due to untimely heat dissipation. Summary of the Invention

[0014] Furthermore, the connecting tube is communicated with the liquid guide tube, and a movable groove is opened at a position on the outer surface of the cleaning plate corresponding to the connecting tube.

[0021] 1.

Even if some rainwater enters the heat dissipation hole through the outer air holes, the air holes inside the annular frame and the air holes inside the partition are staggered, and the rainwater entering the heat dissipation hole can be isolated inside the annular frame and discharged through the drain pipe, thereby preventing rainwater from entering the cabinet and causing adverse effects on the electrical components inside the cabinet.

[0022] 2. In the present invention, by collecting the real-time temperature inside the cabinet and performing comparative analysis, the internal condition of the cabinet can be understood and the cabinet can be cooled immediately. Compared with the prior art that uses heat dissipation blades to continuously dissipate heat, this can ensure the operating efficiency of the electrical components inside the cabinet while avoiding unnecessary power consumption.

[0023] In addition, by collecting and analyzing the wind speed outside the heat dissipation hole during the heat dissipation process, it is possible to determine whether the filter corresponding to the heat dissipation hole is blocked, and when the blockage of the filter affects the heat dissipation of the cabinet, a corresponding signal is generated and sent to the execution module. The execution module controls the cleaning cotton to rotate on the partition surface to clean the filter according to the received signal, and can timely grasp the actual heat dissipation of the cabinet and process it. In this process, the pulling force of the piston block and the elastic force of the annular spring work together to make the cleaning liquid slowly infiltrate the cleaning cotton, thereby improving the cleaning efficiency of the cleaning cotton and avoiding the waste caused by the continuous outflow of the cleaning liquid when the cleaning plate is not working.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] Example 1: Figure 1-4 As shown, the electrical automation instrument cabinet with online monitoring and early warning functions proposed by the present invention includes a cabinet body 1, a cabinet door 2 is provided on the front outer surface of the cabinet body 1, and a lock body is provided between the cabinet door 2 and the cabinet body 1, and a plurality of groups of support plates 3 are provided inside the cabinet body 1 from top to bottom, and a plurality of groups of heat-conducting strips 4 for mounting electrical components are fixedly connected at equal distances on the outer surface of the upper end of the support plates 3, which can assist the electrical components in rapid heat dissipation, and a control panel is provided inside the cabinet body 1;

[0038] Heat dissipation holes 5 are provided on the outer surfaces of both sides of the cabinet 1 near the middle, and a partition 16 is fixedly connected to the inside of the heat dissipation hole 5. An annular frame 6 is fixedly connected to the position of the inner surface of the cabinet 1 corresponding to the heat dissipation hole 5, and a plurality of groups of air holes 7 are provided on the outer surface of one side of the annular frame 6 and the outer surface of the partition 16. The cabinet 1 realizes internal and external air exchange through the air holes 7, thereby dissipating heat, and a filter 10 is provided inside the air hole 7 corresponding to the partition 16, and the filter 10 is used to prevent dust from entering the interior of the cabinet 1.

[0039] The air holes 7 corresponding to the annular frame 6 and the partition 16 are distributed in a circular staggered manner, and an air guide ring 14 is fixedly connected to the outer surface of one side of the air hole 7. The inner diameter of the air guide ring 14 gradually decreases from the direction of the air hole 7 to the outside, and the rainwater entering the air guide ring 14 can be diverted to the outside. The outer surface of the lower end of the annular frame 6 is fixedly connected to a drain pipe 15, and one end of the drain pipe 15 passes through the outside of the cabinet 1. The drain pipe 15 is communicated with the annular frame 6. Even if some rainwater enters the interior of the heat dissipation hole 5 through the air holes 7 on the outside, the rainwater entering the heat dissipation hole 5 can be isolated inside the annular frame 6 through the staggered position of the air holes 7 inside the annular frame 6 and the air holes 7 inside the partition 16, and discharged through the drain pipe 15.

[0040] A motor 11 is provided on the outer surface of the annular frame 6, near the middle of one side inside the cabinet 1, and the output end of the motor 11 passes through the inside of the annular frame 6 and is fixedly connected to a rotating column 12. A heat dissipation blade 13 is provided on the outer surface of the rotating column 12. The heat dissipation blades 13 corresponding to the two groups of annular frames 6 are in opposite directions. The two groups of motors 11 are controlled to run at the same time, and the rotating column 12 drives the heat dissipation blades 13 to rotate. The air enters the interior of the cabinet 1 through the corresponding heat dissipation holes 5 under the action of one group of heat dissipation blades 13. The hot air inside the cabinet 1 is pushed by the airflow and the action of the other group of heat dissipation blades 13 and is discharged through the other group of heat dissipation holes 5, thereby realizing heat dissipation inside the cabinet 1.

[0041] Example 2: Figure 2-7 As shown, the difference between this embodiment and embodiment 1 is that a cleaning mechanism 8 for preventing the filter 10 from being blocked is provided between the two sets of partitions 16 and the cabinet 1. The cleaning mechanism 8 includes a fixing ring 801, an annular groove 802, an annular spring 803 and an annular block 804. The outer surface of the cabinet 1 is fixedly connected to the position corresponding to the heat dissipation hole 5 with a fixing ring 801, and an annular groove 802 is provided inside the fixing ring 801. The inner surface of the annular groove 802 is rotatably connected to the annular block 804.

[0042] A cleaning plate 805 is fixedly connected to the inside of the annular block 804, and a cleaning cotton 806 is embedded in a detachable manner on one side of the outer surface of the cleaning plate 805. A movable shaft 807 is fixedly connected to the side of the outer surface of the cleaning plate 805 close to the partition 16, and the movable shaft 807 passes through the partition 16 and extends to the inside of the heat dissipation hole 5. One end of the movable shaft 807 is fixedly connected to a magnet 808, and the movable shaft 807 is movably connected to the partition 16. An electromagnet 809 is provided on the end of the outer surface of the rotating column 12 close to the magnet 808. After receiving the cleaning signal of the left heat dissipation hole 5 or the right heat dissipation hole 5, the execution module turns on the electromagnet 809 on the corresponding side. The magnetism of the electromagnet 809 is opposite to that of the corresponding magnet 808. Under the action of the magnetic adsorption force, the magnet 808 drives the movable shaft 807 to move in the direction of the electromagnet 809 until it is completely fitted with the electromagnet 809.

[0043] At this time, the cleaning cotton 806 is in contact with the partition 16, and the movable column rotates with the rotating column 12 under the adsorption force of the electromagnet 809 and the magnet 808, and the cleaning cotton 806 cleans the surface of the filter 10 until Vz≥Vf or Vy≥Vf. At this time, the electromagnet 809 is turned off, and an annular spring 803 is provided inside the annular groove 802. One end of the annular spring 803 is fixedly connected to the annular groove 802, and the other end is a free end. The electromagnet 809 is closed, and the annular block 804 drives the cleaning plate 805 to move away from the partition 16 under the action of the annular spring 803, and the cleaning cotton 806 enters the interior of the fixed ring 801 for storage.

[0044] Example 3: Figure 2-10 As shown, the difference between this embodiment and embodiment 1 and embodiment 2 is that a liquid injection component 9 for automatically injecting cleaning liquid is provided between the cleaning mechanism 8 and the partition 16. The liquid injection component 9 includes a support bar 901, a liquid guide tube 902 and a connecting tube 903;

[0045] The interior of the fixing ring 801 is fixedly connected to a support bar 901, and the outer surface of one side of the support bar 901 is fixedly connected to a liquid guide tube 902. The liquid guide tube 902 is L-shaped, and one end of the liquid guide tube 902 is detachably connected to a liquid storage cylinder. The outer surface of the support bar 901 is fixedly connected to a connecting tube 903 on the side away from the liquid guide tube 902, and the inner diameter of the connecting tube 903 is larger than the inner diameter of the liquid guide tube 902.

[0046] The connecting tube 903 is communicated with the liquid guiding tube 902, and a movable groove 904 is provided on the outer surface of the cleaning plate 805 at a position corresponding to the connecting tube 903. One end of the connecting tube 903 passes through the interior of the movable groove 904 and is movably connected thereto. One end of the inner surface of the movable groove 904 is fixedly connected to a connecting rod 905, and one end of the connecting rod 905 is fixedly connected to a piston block 906. The piston block 906 passes through the interior of the liquid guiding tube 902 and is movably connected thereto. In the process of the movable shaft 807 approaching the electromagnet 809, the connecting rod 905 drives the piston block 906 to be pulled in the direction close to the connecting tube 903. When the electromagnet 809 is in contact with the magnet 1 808, the piston block 906 enters the interior of the connecting tube 903. In the process of the piston block 906 moving inside the liquid guiding tube 902, it forms a pulling force on the inside of the liquid guiding tube 902.

[0047] Through holes are provided on the inner surface of the movable groove 904 at positions corresponding to the two sets of cleaning cotton 806, and the through holes are in communication with the cleaning cotton 806. A piston assembly is provided inside the liquid guide tube 902 between the piston block 906 and the liquid storage cylinder.

[0048] The piston assembly includes a connecting ring 907, a fixing strip 908 and a sealing gasket 909. The connecting ring 907 is provided inside the liquid guide tube 902, and a sealing gasket 909 is provided on the outer surface of the connecting ring 907 close to the piston block 906. Figure 10 As shown, the sealing gasket 909 is concave in an arc shape toward the connecting tube 903 under the action of the pulling force, and a gap is formed between the sealing gasket 909 and the liquid guide tube 902. Therefore, the cleaning liquid inside the liquid storage cylinder and the liquid guide tube 902 enters the interior of the connecting tube 903 through the gap between the sealing gasket 909 and the liquid guide tube 902, and slowly infiltrates the cleaning cotton 806 through the through hole.

[0049] A limiting plug 910 is provided between the sealing gasket 909 and the connecting ring 907, and the sealing gasket 909 is made of soft rubber material, and four sets of fixing strips 908 are fixedly connected to the outer surface of the connecting ring 907 at equal distances. By setting the fixing strips 908 to block one side of the sealing gasket 909, as shown in FIG. Figure 9 As shown, the sealing gasket 909 will not be concave in an arc shape in the direction away from the connecting tube 903 when the piston block 906 enters the interior of the liquid guide tube 902, thereby avoiding the continuous outflow of the cleaning liquid when the cleaning plate 805 is not working and causing waste.

[0050] Example 4: Figure 1-11 As shown, the difference between this embodiment and embodiment 1, embodiment 2, and embodiment 3 is that the control panel includes a processor, a data acquisition module, a data analysis module, and an execution module.

[0051] The data acquisition module is used to collect the real-time temperature Tg inside the cabinet 1, and the data acquisition module is used to receive the heat dissipation signal. After receiving the heat dissipation signal, the wind speed Vz outside the left heat dissipation hole 5 during the heat dissipation process and the wind speed Vy outside the right heat dissipation hole 5 during the heat dissipation process are immediately collected, and then the real-time temperature Tg inside the cabinet 1, the wind speed Vz outside the left heat dissipation hole 5 during the heat dissipation process and the wind speed Vy outside the right heat dissipation hole 5 during the heat dissipation process are sent to the data analysis module through the processor.

[0052] After receiving the real-time temperature Tg inside the cabinet 1, the wind speed Vz outside the left heat dissipation hole 5 during heat dissipation, and the wind speed Vy outside the right heat dissipation hole 5 during heat dissipation, the data analysis module immediately compares and analyzes the operation status of the cabinet 1.

[0053] The specific analysis process is as follows:

[0054] Step 1: Receive the real-time temperature Tg inside the cabinet 1, and compare and analyze the temperature reference value CT stored in the processor with Tg. When Tg ≥ CT, generate a heat dissipation signal, and send the generated heat dissipation signal to the execution module and the data acquisition module;

[0055] After receiving the heat dissipation signal, the execution module controls the two groups of motors 11 to run simultaneously, and the rotating column 12 drives the heat dissipation blades 13 to rotate. Under the action of one group of heat dissipation blades 13, air enters the cabinet 1 through the corresponding heat dissipation holes 5. The hot air inside the cabinet 1 is pushed by the airflow and the action of the other group of heat dissipation blades 13 and discharged through the other group of heat dissipation holes 5 until Tg < CT. Through intelligent real-time monitoring of the temperature inside the cabinet 1, it is convenient to adjust the operating status of the corresponding components according to the condition of the cabinet 1. Compared with the prior art that uses the heat dissipation blades 13 to continuously dissipate heat, it can ensure the operating efficiency of the electrical components inside the cabinet 1 while avoiding unnecessary power consumption.

[0056] When Tg<CT, no treatment is performed;

[0057] Step 2: Receive the wind speed Vz outside the left heat dissipation hole 5 and the wind speed Vy outside the right heat dissipation hole 5 during heat dissipation, and compare and analyze the wind speed reference value Vf stored in the processor with Vz and Vy respectively.

[0058] If Vz<Vf, it means that the filter 10 corresponding to the left heat dissipation hole 5 is blocked, and a left heat dissipation hole 5 cleaning signal is generated and sent to the execution module; if Vz≥Vf, no processing is performed.

[0059] If Vy<Vf, it means that the filter 10 corresponding to the right heat dissipation hole 5 is blocked, and a right heat dissipation hole 5 cleaning signal is generated and sent to the execution module; if Vy≥Vf, no processing is performed.

[0060] After receiving the left heat dissipation hole 5 cleaning signal or the right heat dissipation hole 5 cleaning signal, the execution module turns on the electromagnet 809 on the corresponding side. The magnetism of the electromagnet 809 is opposite to that of the corresponding magnet 1 808.

[0061] Under the action of magnetic adsorption force, magnet 808 drives the movable shaft 807 to move toward the electromagnet 809 until it is completely in contact with the electromagnet 809. At this time, the cleaning cotton 806 is in contact with the partition 16, and the movable column rotates with the rotating column 12 under the action of the adsorption force of the electromagnet 809 and magnet 808, and the cleaning cotton 806 cleans the surface of the filter 10.

[0062] As the movable shaft 807 approaches the electromagnet 809, the connecting rod 905 drives the piston block 906 to be pulled toward the connecting tube 903. When the electromagnet 809 fits with the magnet 1 808, the piston block 906 enters the interior of the connecting tube 903. As the piston block 906 moves inside the catheter 902, it generates a pulling force on the interior of the catheter 902.

[0063] Under the action of the pulling force, the sealing gasket 909 is concave in an arc shape toward the connecting tube 903, and a gap is formed between the sealing gasket 909 and the liquid guide tube 902. Therefore, the cleaning liquid inside the liquid storage cylinder and the liquid guide tube 902 enters the interior of the connecting tube 903 through the gap between the sealing gasket 909 and the liquid guide tube 902, and slowly infiltrates the cleaning cotton 806 through the through hole; the cleaning efficiency of the cleaning cotton 806 is improved until Vz ≥ Vf or Vy ≥ Vf, at which time, the electromagnet 809 is turned off.

[0064] When the electromagnet 809 is closed, the annular block 804 drives the cleaning plate 805 to move away from the partition 16 under the action of the annular spring 803, and the piston block 906 enters the interior of the liquid guide tube 902 again. By setting a fixing bar 908 to block it on one side of the sealing gasket 909, the sealing gasket 909 will not be arc-shapedly concave in the direction away from the connecting tube 903 during the process of the piston block 906 entering the interior of the liquid guide tube 902, thereby avoiding the continuous outflow of cleaning liquid when the cleaning plate 805 is not working, causing waste.

[0065] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
