Description

Technical Field

[0001] The present invention belongs to the technical field of electrical equipment control cabinets, and in particular relates to an electrical equipment control cabinet based on the Internet of Things. Background Art

[0002] The electrical equipment control cabinet based on the Internet of Things is an intelligent device that combines Internet of Things technology, sensor technology, big data platform and artificial intelligence. It is mainly used to improve the management efficiency and operation reliability of electrical equipment.

[0003] Such control cabinets use the Internet of Things technology to achieve remote monitoring, management and intelligent control of electrical equipment, greatly improving the efficiency and safety of electrical equipment. Electrical equipment control cabinets based on the Internet of Things still have certain fire risks during operation. In order to ensure the safety and reliability of the electrical system, traditional electrical equipment control cabinets usually use the method of spraying fire extinguishing media into the cabinet to deal with potential fire risks. Although this fire extinguishing method can effectively extinguish fires in electrical equipment, there are some significant problems. First, the spraying of fire extinguishing media will cause damage to electrical components that are not in the state of fire source, thereby further expanding the losses; secondly, the fire extinguishing process is often started after the fire has occurred, and this time difference may cause the fire to spread further, making it difficult to achieve effective control in a short time.

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present invention, 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, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0033] like Figure 1-2 As shown, an electrical equipment control cabinet based on the Internet of Things in one embodiment of the present invention includes a cabinet 1, and electrical components for controlling electrical equipment are installed in the cabinet 1. A cabinet door 2 is rotatably connected to one side of the cabinet 1. A fire extinguishing mechanism 3 matching the electrical components is fixedly connected to the interior of the cabinet 1. The fire extinguishing mechanism 3 can divide the cabinet 1 into multiple areas, and can perform separate heat dissipation and fire prevention operations on the multiple areas. This avoids further expansion of losses when performing fire extinguishing operations.

[0034] like Figure 1 to Figure 6 As shown, the fire extinguishing mechanism 3 includes a mounting frame 4, a first slide groove 401 is provided on the inner wall of one side of the mounting frame 4, and a strip hole 402 is provided on the inner wall of the other side of the mounting frame 4, the first slide groove 401 and the strip hole 402 are arranged in parallel, and the direction in which the first slide groove 401 and the strip hole 402 are arranged is perpendicular to the horizontal plane. A plurality of placement plates 5 are slidably connected to the mounting frame 4, that is, the plurality of placement plates 5 slide up and down in the mounting frame 4.

[0035] like Figure 1 to Figure 6 As shown, the two ends of the placement plate 5 are fixedly connected with connecting columns 501, one of which is located in the first slide groove 401, and the other connecting column 501 is located in the strip hole 402. The connecting column 501 located in the strip hole 402 is provided with a threaded hole 502, and a locking handle 6 matching the threaded hole 502 is threadedly connected to the connecting column 501. The locking handle 6 passes through the strip hole 402 and is threadedly connected to the threaded hole 502, that is, when the locking handle 6 is tightened, the placement plate 5 and the mounting frame 4 can be locked. By sliding the placement plate 5 on the mounting frame 4, the spacing between two adjacent placement plates 5 can be changed, and the spacing between the upper end surface and the lower end surface of the placement plate 5 and the mounting frame 4 can also be changed.

[0036] like Figure 1 to Figure 6As shown, a fire extinguishing space is formed between the upper end surface of the placement plate 5 and the mounting frame 4, the lower end surface of the placement plate 5 and the mounting frame 4, and between adjacent placement plates 5, and the electrical components of the electrical equipment control cabinet are completely located in the fire extinguishing space. Among them, the fire extinguishing mechanism 3 also includes a first spraying mechanism 7 and a second spraying mechanism 10, the first spraying mechanism 7 is arranged on the upper end surface of the placement plate 5, and the second spraying mechanism 10 is arranged on the lower end surface of the placement plate 5 away from the first spraying mechanism 7. The inner top wall of the mounting frame 4 is also provided with the second spraying mechanism 10, and the inner bottom wall of the mounting frame 4 is also provided with the first spraying mechanism 7.

[0037] Specifically, the first injection mechanism 7 can spray out flame-blocking gas and form an air curtain, and the second injection mechanism 10 can recover the gas sprayed by the first injection mechanism 7. According to the fire situation in the cabinet 1, the second injection mechanism 10 can selectively recover the amount of gas. That is, when the fire is too big, the second injection mechanism 10 does not recycle the gas, and the gas sprayed by the first injection mechanism 7 hits the placement plate 5, and the gas disperses in the cabinet 1 to suppress the fire source. On the contrary, when the fire is small, the gas sprayed only by the first injection mechanism 7 is not enough to extinguish the fire. The second injection mechanism 10 can completely collect the gas sprayed by the first injection mechanism 7, and use other means to extinguish the open flame between the first injection mechanism 7 and the second injection mechanism 10. To reduce the damage caused by the fire source to other electrical components in the cabinet 1.

[0038] In this embodiment, the gas recovered by the second injection mechanism 10 is directly discharged, and the gas discharged by the first injection mechanism 7 is generally air. In order to further improve the fireproof performance of the gas curtain sprayed by the first injection mechanism 7, the gas sprayed by the first injection mechanism 7 can be a gas with fire extinguishing performance such as nitrogen and carbon dioxide. After being recovered by the second injection mechanism 10, the gas recovered by the second injection mechanism 10 can be collected in a recovery tank, and the gas sprayed by the first injection mechanism 7 can be recycled, which improves the fireproof performance while being more energy-saving and environmentally friendly.

[0039] like Figure 1 to Figure 6 As shown, the first spray mechanism 7 includes a first spray hole 8 and a first wind curtain hole 9. The first spray hole 8 is arranged between the first wind curtain hole 9 and the inner wall of the cabinet 1. The air curtain is sprayed from the first wind curtain hole 9. The first spray hole 8 can spray the fire extinguishing medium to realize the fire extinguishing operation of the electrical components.

[0040] like Figure 1 to Figure 6As shown, the second spray mechanism 10 includes a second spray hole 11 and a second air curtain hole 12. The second spray hole 11 is arranged between the second air curtain hole 12 and the inner wall of the cabinet 1. The air curtain is recovered by the second air curtain hole 12. The second spray hole 11 is the same as the first spray hole 8 and can spray out the fire extinguishing medium to extinguish the fire of the electrical components. The second spray hole 11 and the first spray hole 8 can spray out the fire extinguishing medium at the same time. By spraying in the upper and lower directions, the fire extinguishing efficiency can be improved. The second spray hole 11 and the first spray hole 8 can also choose to spray from the second spray hole 11 or the first spray hole 8 according to the location of the fire source, which is conducive to saving the fire extinguishing medium.

[0041] like Figure 1 to Figure 6 As shown, a pump 42 for supplying gas to the first injection mechanism 7 is provided on one side of the cabinet 1, and a first gas outlet pipe 43 is provided between the pump 42 and the first injection mechanism 7. An exhaust pipe 48 is provided on the second injection mechanism 10, and a pump 42 is also provided at one end of the exhaust pipe 48 away from the second injection mechanism 10. The pump 42 matched with the first injection mechanism 7 is used to supply gas to the first injection mechanism 7 so that the first injection mechanism 7 can spray out the air curtain, and the pump 42 matched with the second injection mechanism 10 is used to recover the gas sprayed by the first injection mechanism 7.

[0042] like Figure 1-2 As shown, a fire extinguishing medium supply mechanism 13 is installed on the cabinet 1, and the fire extinguishing medium supply mechanism 13 is used to provide the fire extinguishing medium to the first spraying mechanism 7. Specifically, as Figure 7 to Figure 9 As shown, the fire extinguishing medium supply mechanism 13 includes a storage tank 14, and a first partition 17 is slidably connected in the storage tank 14, and the first partition 17 divides the space in the fire extinguishing medium supply mechanism 13 into a first cavity 21 and a second cavity 22. An air intake valve 15 matching the first cavity 21 is provided on the storage tank 14, and a solenoid valve 16 is provided on the air intake valve 15, and the solenoid valve 16 controls the passage of the air intake valve 15, and a discharge pipe 24 connected to the first ejection hole 8 and the second ejection hole 11 is fixedly connected to the end of the mounting frame 4 away from the air intake valve 15, and a material pump is provided on the discharge pipe 24.

[0043] like Figure 7 to Figure 9As shown, the fire extinguishing medium includes a first fire extinguishing medium 23, and the first fire extinguishing medium 23 is filled in the second cavity 22. The outer wall of the first partition 17 is fixedly connected with a sealing ring 18, and the sealing ring 18 completely seals the gap between the first cavity 21 and the second cavity 22. When the first fire extinguishing medium 23 in the second cavity 22 needs to be used, the solenoid valve 16 closes the passage of the air inlet valve 15, and the first cavity 21 is in a closed state. At this time, the material pump for conveying the fire extinguishing medium will still continuously output. Due to the existence of negative pressure, the first partition 17 will move to the end close to the first cavity 21. When the lower end surface of the first cavity 21 contacts the discharge pipe 24, an adsorption structure is also provided on the storage tank 14 and the first partition 17, and the lower end surface of the first partition 17 and the inner bottom wall of the storage tank 14 can be fitted together through the adsorption structure. At this time, the discharge pipe 24 is located in the second cavity 22 , the solenoid valve 16 is opened, and the material pump can transport the first fire extinguishing medium 23 to the first spray hole 8 and the second spray hole 11 , and spray it out from the first spray hole 8 and the second spray hole 11 .

[0044] like Figure 8 As shown, the adsorption structure includes a first magnet sheet 19 and a second magnet sheet 20, wherein the first magnet sheet 19 is fixedly connected to the first partition plate 17, and the second magnet sheet 20 is fixedly connected to the inner wall of the storage tank 14. The second magnet sheet 20 is an electromagnet. When the fire extinguishing operation is completed, the second magnet sheet 20 changes its magnetic pole so that the second magnet sheet 20 and the first magnet sheet 19 repel each other, and the lower end surface of the first partition plate 17 is located at the upper end of the discharge pipe 24. At this time, the solenoid valve 16 closes the passage of the air inlet valve 15, and inflates the first cavity 21 through the material pump, and the first partition plate 17 will be away from the second magnet sheet 20. Of course, the repulsive force between the second magnet sheet 20 and the first magnet sheet 19 alone is sufficient to form the first cavity 21, that is, it is not necessary to inflate the first cavity 21.

[0045] The first fire extinguishing medium 23 is generally fire extinguishing dry powder, carbon tetrachloride, nitrogen, carbon dioxide or other fire extinguishing media.

[0046] like Figure 7 to Figure 9 As shown, the fire extinguishing medium also includes a second fire extinguishing medium 47. A partition mechanism 25 is installed in the second cavity 22, and the partition mechanism 25 forms a third cavity 26 at the upper end of the second cavity 22, and the second fire extinguishing medium 47 is stored in the third cavity 26. The partition mechanism 25 can transport the fire extinguishing medium into the second cavity 22, so that the first fire extinguishing medium 23 and the second fire extinguishing medium 47 are mixed, and finally transported to the cabinet 1 through the discharge pipe 24 for fire extinguishing.

[0047] like Figure 7 to Figure 9As shown, the partition mechanism 25 includes a second partition plate 27, which is conical and has an opening. A plurality of first connecting rods 29 matching the openings are fixedly connected to the second partition plate 27, a connecting plate 30 is slidably connected to the first connecting rod 29, a second connecting rod 31 is fixedly connected to the lower end surface of the connecting plate 30, and a baffle 28 is fixedly connected to the end of the second connecting rod 31 away from the connecting plate 30. A third magnet block 32 is fixedly connected to the upper end of the first connecting rod 29, and a fourth magnet block 33 is fixedly connected to the connecting plate 30. The third magnet block 32 is an electromagnet. When the second fire extinguishing medium 47 in the third cavity 26 needs to enter the second cavity 22, the third magnet block 32 changes its magnetic pole so that the third magnet block 32 and the fourth magnet block 33 repel each other. The baffle 28 is located at the lower end of the opening of the second partition plate 27, and the second fire extinguishing medium 47 first falls on the baffle 28 and then falls into the second cavity 22. The upper end surface of the baffle plate 28 is provided with an inclined surface 2801 , and the inclined surface 2801 can prevent the second fire extinguishing medium 47 from staying on the upper end surface of the baffle plate 28 .

[0048] If you want the third magnet block 32 and the fourth magnet block 33 to be attracted, you only need to change the magnetic pole of the third magnet block 32 so that the fourth magnet block 33 and the third magnet block 32 are attracted to each other. The fourth magnet block 33 will move toward one end of the third magnet block 32, and at the same time move the connecting plate 30, the second connecting rod 31 and the baffle 28 upward.

[0049] like Fig.11 As shown, the second fire extinguishing medium 47 includes a protective layer 4701, and a fire extinguishing agent 4702 is arranged inside the protective layer 4701. The protective layer 4701 has a certain fire extinguishing effect and can completely wrap the fire extinguishing agent 4702. When the second fire extinguishing medium 47 is sprayed into the cabinet 1, it is possible that the protective layer 4701 is broken. If the protective layer 4701 is broken, the fire extinguishing agent 4702 is sprayed out, and the spraying of the fire extinguishing agent 4702 can play a secondary fire extinguishing role.

[0050] Specifically, whether the second fire extinguishing medium 47 will rupture is determined according to the spraying force and the landing point of the sprayed second fire extinguishing medium 47. Generally, a fire monitoring mechanism is provided in the cabinet 1, and the fire monitoring mechanism monitors in real time and uploads data. After the fire data is uploaded, the first spray mechanism 7 and the second spray mechanism 10 can perform corresponding spraying actions.

[0051] The protective layer 4701 is generally a combination of a permeable membrane, a fire extinguishing fiber, and a protective membrane. The protective membrane is arranged between the protective layer 4701 and the fire extinguishing agent 4702, and the permeable membrane is arranged at one end of the protective membrane away from the fire extinguishing agent 4702. The protective membrane is preheated and ruptured, and the fire extinguishing agent 4702 penetrates into the protective layer 4701. When the protective layer 4701 contacts the fire source, the fire extinguishing agent 4702 and the protective layer 4701 cooperate to achieve simple fire extinguishing. When the second fire extinguishing medium 47 ruptures, the fire extinguishing agent 4702 flows out, which can further extinguish the fire source.

[0052] Preferably, a plurality of explosion points are provided in the protective layer 4701 , and the explosion points are formed by materials that expand with heat and contract with cold. When the second fire extinguishing medium 47 enters the fire source, the explosion points are heated to the explosion temperature, and the explosion points explode to spray the fire extinguishing agent 4702 to the surroundings, thereby increasing the fire extinguishing range of the second fire extinguishing medium 47 .

[0053] After use, the first fire extinguishing medium 23 and the second fire extinguishing medium 47 will remain inside the cabinet 1, causing trouble for cleaning inside the cabinet 1. To solve the above problem, a recovery mechanism 34 is also provided on the cabinet 1, and the recovery mechanism 34 extracts the fire extinguishing medium in the cabinet 1 by means of negative pressure. During normal use, if the cabinet 1 is in a high temperature state, the recovery mechanism 34 can also extract the heat in the cabinet 1 by means of negative pressure to achieve cooling of the cabinet 1.

[0054] like Figure 1 to Figure 4 As shown, the recovery mechanism 34 includes a recovery plate 35, the recovery plate 35 completely covers the inner wall of the cabinet 1, and a plurality of recovery holes 3501 are opened on the recovery plate 35, and the fire extinguishing medium enters from the recovery holes 3501. The recovery mechanism 34 also includes a filtering mechanism 38, a first recovery pipe 36 is installed between the recovery mechanism 34 and the filtering mechanism 38, and a second recovery pipe 37 is installed between the first recovery pipe 36 and the filtering mechanism 38. The fire extinguishing medium enters the filtering mechanism 38 from the recovery holes 3501, the first recovery pipe 36, and the second recovery pipe 37 in sequence.

[0055] like Fig.10 As shown, the filtering mechanism 38 includes a filtering box 39, and a boosting fan 40 is rotatably connected inside the filtering box 39. The boosting fan 40 can complete the crushing and stirring of the fire extinguishing medium. A filtering structure 41 is fixedly connected to the inner wall of one side of the filtering box 39. The filtering structure 41 can prevent the fire extinguishing medium from entering the filtering box 39 and then being discharged.

[0056] like Fig.10As shown, a water replenisher 46 is also installed at the upper end of the filter box 39. The water replenisher 46 can add medium into the filter box 39 so that the first fire extinguishing medium 23 and the second fire extinguishing medium 47 can be reused for a second time. Generally, the first fire extinguishing medium 23 and the second fire extinguishing medium 47 are both alkaline fire extinguishing media. After being crushed by the booster fan 40 in the filter box 39, a foaming agent such as protein hydrolyzate or licorice powder and a stabilizer such as ferric chloride are added and mixed to interact with each other to generate a large amount of carbon dioxide gas and aluminum hydroxide precipitation, which react with the foaming agent to form many bubbles, thereby generating foam and forming a third fire extinguishing medium. A feed pipe 45 is installed between the filter mechanism 38 and the discharge pipe 24. The third fire extinguishing medium is transported to the discharge pipe 24 through the feed pipe 45, and then transported to the cabinet 1 by the discharge pipe 24 to achieve fire extinguishing.

[0057] like Figure 1-2 As shown, a second air outlet pipe 44 is also provided on the first air outlet pipe 43 . When the first injection mechanism 7 and the second injection mechanism 10 are not needed to form an air curtain and the fire extinguishing medium in the cabinet 1 needs to be recovered, the gas pumped by the pump 42 is discharged from the second air outlet pipe 44 .

[0058] like Figure 1 to Figure 4 As shown, an air inlet pipe 4201 is installed between the filter mechanism 38 and the pump 42, and an air inlet end 3701 is installed on the second recovery pipe 37. When the first injection mechanism 7 and the second injection mechanism 10 form an air curtain and the fire extinguishing medium needs to be recovered, the first recovery pipe 36, the second recovery pipe 37, the filter mechanism 38, and the pump 42 form a passage; when the fire extinguishing medium does not need to be recovered, the air inlet end 3701, the second recovery pipe 37, the filter mechanism 38, and the pump 42 form a passage.

[0059] When the electrical equipment control cabinet based on the Internet of Things is in use, the fire monitoring mechanism will first monitor the situation in the cabinet 1 in real time. When the temperature of the fire monitoring mechanism is too high, the first spray mechanism 7 and the second spray mechanism 10 will cooperate to form an air curtain, and a simple cooling will be achieved through the air curtain. If the air curtain cannot cool down, the recovery mechanism 34 will be used to extract the wind of the electrical components in the cabinet 1 in an exhaust manner. The wind of the air curtain is partially extracted by the recovery mechanism 34, and the wind generated by the air curtain is cold wind. The cold wind passes through the electrical components and can cool the electrical components.

[0060] If the temperature of the electrical component still does not drop, it is determined that a short circuit has occurred. The fire extinguishing medium supply mechanism 13 provides the first spray mechanism 7 and the second spray mechanism 10 with a fire extinguishing medium, spraying a layer of fire extinguishing medium around and on the electrical component to prevent the fire from spreading. The air curtain can also prevent the fire from spreading. The fire extinguishing medium supply mechanism 13 first provides the first fire extinguishing medium 23 to the first spray mechanism 7 and the second spray mechanism 10 for the cabinet 1 to extinguish the fire. If the cabinet 1 cannot extinguish the fire, the fire extinguishing medium supply mechanism 13 provides the first fire extinguishing medium 23 to the second fire extinguishing medium 47 for extinguishing the fire. After the first fire extinguishing medium 23 and the second fire extinguishing medium 47 are consumed, the fire extinguishing medium in the cabinet 1 is recovered by the recovery mechanism 34, and the medium is added to the fire extinguishing medium, and the consumed fire extinguishing medium is crushed so that the added medium and the recovered fire extinguishing medium form a foam fire extinguishing agent. Through the cooperation of the filtering mechanism 38 and the feeding pipe 45, the foam fire extinguishing agent is transported to the cabinet 1 to achieve fire extinguishing.
