Description

Technical Field

[0001] The present invention belongs to the technical field of electrical cabinet protection, and in particular relates to a protective device for outdoor electrical cabinets. Background Art

[0002] Outdoor electrical cabinets are cabinets used to protect electrical components. They are widely used in the chemical industry, transportation industry, power systems, industry, nuclear power industry, fire safety monitoring, etc. In daily life, we often see them in outdoor cameras, transformers, and some outdoor electrical occasions. However, the existing outdoor electrical cabinets still have certain defects and shortcomings in actual use.

[0003] While existing outdoor electrical cabinets offer some degree of waterproofing, they still offer limited protection against splashing rain. Furthermore, insects and other small insects pose a significant threat to electrical cabinets. These insects can enter through gaps in the cabinet or through ventilation windows, nesting and defecating between the protective screen and electrical components, or even directly contacting them, causing short circuits and poor contact. Summary of the Invention

[0004] The purpose of the present invention is to provide a protective device for outdoor electrical cabinets to solve the waterproof and insect-proof problems in the prior art.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A protective device for outdoor electrical cabinets includes a cabinet body and a control integrated panel. A wall panel is fixed to the side of the cabinet body, and an exhaust window and a collection window are provided on the surface of the wall panel. A closing panel is installed on the inner side of the wall panel, and side panels are installed on both sides of the closing panel. The closing panel, side panels and wall panel form an area for waterproofing and preventing insects. A collection box is slidably installed inside the collection window, and the collection box is used to collect mosquitoes.

[0007] Preferably, a plurality of louver panels are installed inside the exhaust window, a mounting groove is provided on one side of the closing plate, a filter plate is installed on the mounting groove, a cooling fan is installed on one side of the filter plate, and the cooling fan corresponds to the exhaust window.

[0008] Preferably, a collecting space is provided inside the collecting box, a communicating port communicating with the collecting space is provided on one side of the collecting box, and an assembling block communicating with the collecting space is provided below the communicating port.

[0009] Preferably, a slope is provided at the bottom of the closing plate, a slope is provided above the slope, and a slope is provided on one side of the collecting box. The slope is parallel to the slope.

[0010] Preferably, the surface of the inclined plate in contact with the inclined surface is covered with a magnetic sticker. The magnetic sticker can be adsorbed on the surface of the inclined surface (metal material), thereby facilitating the stable installation and sliding removal of the collection box.

[0011] Preferably, a collection box is slidably mounted inside the assembly block, and a capacity slot is provided at the rear end of the collection box. When the collection box is installed in the assembly block, the dead mosquitoes will be directly stored in the capacity slot. During maintenance, it is only necessary to pull out the collection box and clean the dead mosquitoes in the capacity slot.

[0012] Preferably, a handle is fixed to the outer wall of the collection box, and a shielding plate is provided above the handle. The handle can facilitate the pulling out of the collection box, and the shielding plate improves the rainproof function of the collection box and prevents rainwater from entering.

[0013] Preferably, a near-infrared sensor is installed on the inner wall of the inclined plate, a protective net is installed below the near-infrared sensor, and a high-voltage net is installed below the protective net.

[0014] Preferably, the electrical control of the cooling fan is connected to the control integrated panel, and the electrical signal of the near-infrared sensor is connected to the control integrated panel.

[0015] Preferably, an inclined guide chamber is provided at the bottom of the collecting box, a covering plate is installed at the front end of the inclined guide chamber, protrusions are provided at both ends of the covering plate, and a groove that slides with the protrusions is opened at the front end of the collecting box.

[0016] Preferably, a rack is provided at the center of one side of the cover plate, a built-in groove is provided in the collection box, a motor is installed inside the built-in groove, and an output end of the motor is connected to a gear meshing with the rack.

[0017] The technical solution of the present invention has the following beneficial effects:

[0018] 1. When water enters the electrical cabinet through the exhaust window, the accumulated water will be temporarily stored in the interval and then discharged from the bottom of the collection window. It will not directly enter the cabinet, thereby improving the safety protection inside the cabinet.

[0019] 2. When mosquitoes fly between the protective net and the high-voltage net and touch both the protective net and the high-voltage net at the same time, the high-voltage current will pass through the mosquito's body, forming an instantaneous current loop. The high-voltage electricity will instantly break through the mosquito's body, causing the mosquito to die. The dead mosquito body will fall inside the inclined guide chamber, and the gear rotation will drive the cover plate to move, thereby detaching from the outlet end of the inclined guide chamber and realizing automatic discharge of the mosquito body.

[0020] 3. This device is both waterproof and insect-proof. The electric shock of mosquitoes will produce an odor, which will diffuse from the connecting port; or the odor will rise and be blown out of the cabinet by the cooling fan. There will be no residual odor in the area that affects the air inside the cabinet. The waterproof and insect-proof devices complement each other. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. 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.

[0041] Example 1:

[0042] refer to Figure 1-Figure 3 A protective device for outdoor electrical cabinets includes a cabinet body 10 and a control integrated panel 11. A wall panel 13 is fixed to the side of the cabinet body 10. An exhaust window 20 and a collection window 30 are opened on the surface of the wall panel 13.

[0043] A closing plate 202 is installed on the inner side of the wall panel 13, and side panels 203 are installed on both sides of the closing plate 202. The closing plate 202, the side panels 203 and the wall panel 13 form an area for waterproofing and insect prevention.

[0044] In the above solution, the collection window 30 is positioned below the exhaust window 20, within the space formed by the closing panel 202, the side panels 203, and the wall panel 13. When rainwater enters the electrical cabinet through the exhaust window 20, the accumulated water is temporarily stored within this space and then drains from below the collection window 30, preventing it from directly entering the cabinet 10. This improves the safety and protection of the cabinet 10. Furthermore, when mosquitoes enter through the exhaust window 20, they are also directly transported to the space formed by the closing panel 202, the side panels 203, and the wall panel 13, preventing them from directly entering the cabinet 10 and ensuring safe operation of the equipment.

[0045] refer to Figure 3 and Figure 4, a plurality of louver plates 201 are installed inside the exhaust window 20, a mounting groove 204 is opened on one side of the closing plate 202, a filter plate 205 is installed on the mounting groove 204, a cooling fan 206 is installed on one side of the filter plate 205, and the cooling fan 206 corresponds to the exhaust window 20;

[0046] In the above scheme, the cooling fan 206 is set at the position corresponding to the exhaust window 20. The cooling fan 206 extracts the heat inside the cabinet 10 and blows it toward the exhaust window 20 to discharge the heat through the louver 201, thereby keeping the internal temperature of the switch cabinet within a reasonable range and preventing the equipment from being damaged or the performance degradation due to overheating; the louver 201 here is set to be tilted downward, which can greatly prevent rainwater from entering through the exhaust window 20, and at the same time prevent external debris or larger insects from directly entering the switch cabinet, thereby protecting the safety of the internal equipment; the filter plate 205 is made of nylon fiber, polypropylene and other materials, the purpose of which is to isolate the area formed by the closing plate 202, the side plate 203 and the wall plate 13 from the outside world, and prevent dust from entering the cabinet 10 through the area. Therefore, the dust is isolated in the area and does not enter the cabinet 10. While ensuring the ventilation effect, the filter plate 205 also prevents mosquitoes from passing through and entering the cabinet 10, thus controlling the mosquitoes in the area formed by the closing plate 202, the side plate 203 and the wall plate 13.

[0047] It is worth noting that: the power supply of the cooling fan 206 comes directly from the cabinet 10, and the electronic control of the cooling fan 206 is connected to the control integrated panel 11, and the operation of the cooling fan 206 is controlled by the control integrated panel 11. Referring to the existing technical solution (matched with the corresponding temperature sensor, linked to the control integrated panel 11, so as to achieve the purpose of automatically starting and stopping the cooling fan 206 according to the temperature), and the control integrated panel 11 here is a device that integrates multiple control functions on a panel, which is usually used for centralized management and operation of various devices or systems. It provides users with a unified and convenient operation interface by integrating different control modules and interfaces, thereby improving the operating efficiency and management level of the equipment (including signal output, input, processor and control logic, display and interactive interface, communication module, etc.).

[0048] The top of the cabinet body 10 is provided with a sloping roof 12; the sloping roof 12 further prevents rainwater from entering from the inside of the exhaust window 20. Combined with the downwardly inclined louver 201, even if rainwater may still enter, the amount of rainwater entering is greatly reduced, and there will not be too much rainwater retained in the interval formed by the closing plate 202, the side panel 203 and the wall panel 13.

[0049] Example 2:

[0050] refer to Figure 5-Figure 9A collection box 40 is slidably mounted inside the collection window 30. A collection space 402 is provided inside the collection box 40. A communication port 403 communicating with the collection space 402 is provided on one side of the collection box 40. An assembly block 404 communicating with the collection space 402 is provided below the communication port 403.

[0051] In the above scheme, insects that enter the interval through the louver boards 201 will not be able to enter due to the constant spacing of the louver boards 201; and insects and mosquitoes that enter the interval have only one exit, the collection box 40, and the insects will fly downward and enter the collection space 402 of the collection box 40. The collection box 40 has two exits, one is the connecting port 403 and the other is the assembly block 404. The mosquitoes that do not fly out may die in the collection space 402, and their bodies will fall into the assembly block 404; similarly, when there is too much rain, they will also fall into the assembly block 404, and then be discharged from the assembly block 404 to the outside of the cabinet 10.

[0052] Further references Figure 6 A slope 207 is provided at the bottom of the closing plate 202 , a slope 208 is provided above the slope 207 , and a slope plate 401 parallel to the slope 207 is provided on one side of the collecting box 40 .

[0053] In the above scheme, when the collection box 40 is completely installed inside the collection window 30, its inclined surface 207 and the inclined plate 401 fit together, and the top of the inclined plate 401 is against the bottom of the inclined platform 208; it is set in an inclined manner, so that the direction of mosquitoes flying downward will gradually decrease, thereby guiding the mosquitoes to fly downward; at the same time, the mosquito corpses will also be convenient to slide from the inclined plate 401 into the collection space 402 for collection.

[0054] Preferably, the surface of the inclined plate 401 in contact with the inclined surface 207 is covered with a magnetic sticker. The magnetic sticker can be adsorbed on the surface of the inclined surface 207 (metal material), thereby facilitating the stable installation and sliding removal of the collection box 40.

[0055] Preferred reference Figure 6-Figure 9 A collection box 405 is slidably assembled inside the assembly block 404 , and a capacity slot 406 is opened at the tail end of the collection box 405 .

[0056] In a preferred embodiment, the collection box 405 is installed in the assembly block 404, and the dead mosquitoes are directly stored in the capacity tank 406. During maintenance, it is only necessary to pull out the collection box 405 and clean the dead mosquitoes in the capacity tank 406.

[0057] It should be noted that there is a gap around the collecting box 405 and the assembly block 404 (front and two sides). The gap is used to drain rainwater entering from the exhaust window 20. While draining water, it does not affect the independent use of the collecting box 405, thereby improving the integrity of the overall solution.

[0058] Further references Figure 10 A handle 407 is fixed to the outer wall of the collection box 40, and a shielding plate 408 is provided above the handle 407. The handle 407 can facilitate the pulling and pulling of the collection box 40, and the shielding plate 408 improves the rainproof function of the collection box 40 to prevent rainwater from entering.

[0059] Example 3:

[0060] refer to Figures 8-11 , a near infrared sensor 50 is installed on the inner wall of the inclined plate 401, a protective net 501 is installed below the near infrared sensor 50, and a high voltage net 502 is installed below the protective net 501;

[0061] In the above solution, the near-infrared sensor 50 is embodied as an insect monitoring device using a near-infrared sensor. The core principle of the near-infrared sensor is that it emits near-infrared light of a specific wavelength. When insects fly over the monitoring area, these light rays are interfered with or scattered. The sensor receives the near-infrared modulated signal backscattered by the insects and converts it into an electrical signal for analysis and processing.

[0062] More specifically, the electrical signal of the near-infrared sensor 50 is connected to the control integrated panel 11. A battery is provided inside the cabinet 10 to supply power to the protection network 501 and the high-voltage network 502. The battery is supplied with power by the cabinet 10, or a separate power switch is used. The circuits of the protection network 501 and the high-voltage network 502 are electrically controlled and connected to the control integrated panel 11. The collection box 40 is provided with a transformer, capacitor, diode, rectifier circuit, etc. that must cooperate with the protection network 501 and the high-voltage network 502. The power supply of the protection network 501 and the high-voltage network 502 is connected to the battery inside the cabinet 10.

[0063] When a mosquito passes by the near-infrared sensor 50, the near-infrared sensor 50 sends an electrical signal to the control integrated panel 11. The control integrated panel 11 processes the signal and issues a control instruction. The low-voltage power provided by the battery is quickly increased to 500 volts through the booster. After passing through the compressed rectifier circuit of the capacitor and the diode, the voltage is further increased to 1500 volts. The high-voltage direct current is supplied to the high-voltage grid 502. Here, the protection net 501 is not charged. There is a certain distance between the protection net 501 and the high-voltage grid 502. When the mosquito flies into the protection net 501 and the high-voltage grid 502, the voltage is increased to 500 volts. 02, and simultaneously contacts the protective net 501 and the high-voltage net 502. The high-voltage current will pass through the mosquito's body, forming an instantaneous current loop. The high-voltage electricity will instantly break through the mosquito's body, killing the mosquito, and the dead mosquito body will fall into the capacity slot 406. Because the electric shock to the mosquito will produce odor, the odor will spread from the communication port 403; or the odor will rise and be blown out of the cabinet 10 by the cooling fan 206. No residual odor will affect the air inside the cabinet 10 in the interval, that is, the waterproof and insect-proof devices complement each other.

[0064] It should be noted that: Figure 11 Here, the control command portion of the integrated panel 11 is connected to the time-delay disconnect relay KT, which delays the battery power supply in the cabinet 10. If there are no mosquitoes entering for a long period of time, the battery power supply is completely disconnected. The use of the near-infrared sensor 50 and the time-delay disconnect relay can reduce energy loss, eliminating the need for continuous battery power supply to the high-voltage grid 502.

[0065] Example 4:

[0066] refer to Figure 12-17 The collecting box 40 has an inclined guide chamber 60 at the bottom, a covering plate 601 is installed at the front end of the inclined guide chamber 60, protrusions 602 are provided at both ends of the covering plate 601, and a groove 603 that slides with the protrusion 602 is opened at the front end of the collecting box 40.

[0067] In the above scheme, the mosquito corpses that are electrocuted to death by the high-voltage network 502 will directly fall into the inclined guide chamber 60 and gather. The inclined guide chamber 60 is set to an inclined state so that it can gather the mosquito corpses while also guiding the mosquito corpses out of the inclined guide chamber 60. The covering plate 601 slides with the groove 603 through the protrusion 602. It only needs to push the covering plate 601 upward to complete the cleaning of the mosquito corpses inside the inclined guide chamber 60.

[0068] In a preferred embodiment, a rack 607 is provided at the center of one side of the cover plate 601, a built-in slot 604 is provided in the collection box 40, a motor 605 is installed inside the built-in slot 604, and an output end of the motor 605 is connected to a gear 606 that meshes with the rack 607;

[0069] In a preferred embodiment, the control method of motor 605 adopts a timing control method, with the set time being one day, three days, one week, etc.; specifically, it is controlled by a mechanical timer, an electronic timer, or an Internet of Things linkage (or the electrical control signal of motor 605 is connected to the control integrated panel 11 for unified setting); when motor 605 is started, the drive gear 606 rotates, thereby driving the cover plate 601 to move, thereby separating from the outlet end of the inclined guide chamber 60. Each time the cover plate 601 is lifted upward, it lasts for no less than thirty seconds (after thirty seconds, the motor 605 starts to reverse again, causing the inclined guide chamber 60 to reset, that is, the cover plate 601 blocks the outlet end of the inclined guide chamber 60, preventing mosquitoes from entering from the outlet end of the inclined guide chamber 60). This ensures that the mosquito carcasses are discharged from the outlet end of the inclined guide chamber 60, thereby realizing the function of automatically discharging the mosquito carcasses, without the need to manually remove the collection box 405; this embodiment eliminates the use of the collection box 405, and instead uses the inclined guide chamber 60 to collect and automatically discharge the mosquito carcasses. The periodic control of the use of motor 605 can save energy.

[0070] The specific implementation process of the present invention is as follows:

[0071] The cooling fan 206 extracts heat from the cabinet 10 and blows it toward the exhaust window 20 to exhaust the heat through the louver 201 .

[0072] When a mosquito passes by the near-infrared sensor 50, the near-infrared sensor 50 sends an electrical signal to the control integrated panel 11. The control integrated panel 11 processes the signal and issues a control instruction. The low-voltage power provided by the battery is boosted and the voltage is quickly increased to 500 volts. After passing through the compressed rectifier circuit of the capacitor and the diode, the voltage is further increased to 1500 volts. The high-voltage direct current is supplied to the high-voltage grid 502. Here, the protection grid 501 is not charged. There is a certain distance between the protection grid 501 and the high-voltage grid 502. When a mosquito flies into the protection grid 501 and the high-voltage network 502, and at the same time contact the protective network 501 and the high-voltage network 502. The high-voltage current will pass through the mosquito's body, forming an instantaneous current loop. The high-voltage electricity will instantly break through the mosquito's body, thereby killing the mosquito, and the dead mosquito body will fall into the capacity slot 406; because the electric shock will produce odor, the odor will spread from the connecting port 403; or the odor will rise and be blown out of the cabinet 10 by the cooling fan 206, and no residual odor will affect the air inside the cabinet 10 in the interval.
