Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and more specifically, it relates to an electric energy metering box based on PC + ASA materials. Background Art

[0002] An electric energy metering box is a box used in the power system to install electric energy metering instruments, transformers, and secondary circuits. It is the overall metering device and auxiliary equipment necessary for metering electric energy. It includes electric energy meters, metering voltage and current transformers and their secondary circuits, electric energy metering panels, cabinets, boxes, etc. Its main function is to accurately measure electric energy, protect the metering device from external interference and damage, and at the same time facilitate the daily maintenance of power management personnel.

[0003] The electric energy metering box can be installed in a suspended or floor-mounted manner. According to the installation environment, it can be divided into indoor type and outdoor type. According to the manufacturing materials, it can be divided into metal metering boxes and non-metal metering boxes. According to the number and specifications of the installed electric energy meters, it can be divided into single-phase single-meter position metering boxes, three-phase single-meter position metering boxes, centralized multi-meter position single-phase electric energy meter metering boxes, and centralized multi-meter position three-phase electric energy meter metering boxes.

[0004] In tropical regions, the usage environment of electric energy metering boxes usually has characteristics such as high temperature, high humidity, heavy rain, and many insects. These environmental conditions pose higher requirements for the material selection, sealing performance, heat dissipation design, etc. of the electric energy metering box. For example, high temperature and high humidity environments may cause corrosion of metal materials and aging of non-metal materials, thus affecting the service life and safety of the metering box. Heavy rain environments require the metering box to have good waterproof performance to prevent rainwater from seeping into the box interior and causing electrical failures. In addition, small insects such as flying insects and ants commonly found in tropical regions may enter the interior through the openings or gaps of the metering box, come into contact with electronic components, resulting in short circuits or other electrical failures and interfering with the normal operation of the equipment.

[0005] Especially for the suspended metering box, since the diameter of the opening at the bottom extending into the circuit wires is fixed, when the diameter of the wire is smaller than the opening, there will be a gap between the opening and the wire. This gap is more likely to become a passage for flying insects to enter in tropical regions, increasing the risk of equipment failure. Therefore, for the electric energy metering box used in tropical regions, special consideration needs to be given to the sealing design and insect prevention measures to ensure the long-term stable operation of the equipment.

[0006] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

[0007] Aiming at the deficiencies existing in the prior art, the purpose of the present invention is to provide an electric energy metering box based on PC + ASA materials.

[0008] The above technical object of the present invention is achieved through the following technical solutions: An electric energy metering box based on PC + ASA materials, including a box body, a wire passing hole is opened at the bottom of the box body, a cavity is opened inside the box body, several components and an insect prevention component are arranged in the cavity, and the insect prevention component is arranged close to the wire passing hole. A baffle is arranged directly above the wire passing hole, and the baffle is in contact with the edge of the insect prevention component; The insect prevention component includes an insect prevention cover and a stopper. The insect prevention cover is in contact with the baffle. A cavity is arranged inside the stopper and a spray head is arranged in the cavity. Several guiding channels are arranged in an array on the stopper and communicate with the cavity. Infrared sensors for monitoring in real time whether flying insects enter are arranged on the inner walls of several guiding channels. A control panel is arranged on the outer wall of the box body. When one of the infrared sensors is blocked, the spray head sprays insecticidal gas. When several infrared sensors are blocked, the spray head stops spraying.

[0009] The present invention is further arranged as follows: The guiding channel includes a vertical part and a horizontal part. There are two infrared sensors, which are respectively arranged at the connection of the horizontal part and the vertical part and on the side of the horizontal part far from the vertical part.

[0010] The present invention is further arranged as follows: A guiding surface communicating with the vertical section is arranged on the cavity. A rotating plate is arranged on the side of the vertical section far from the guiding surface. A worm storage cavity is arranged on the stopper. The rotating plate is rotatably connected to the opening of the worm storage cavity and is used to block the worm storage cavity. When the flying insect falls onto the top surface of the rotating plate, the rotating plate rotates towards the worm storage cavity. When the flying insect falls into the worm storage cavity, the rotating plate returns to its original state and remains horizontal.

[0011] The present invention is further arranged as follows: A receiving box is detachably connected to the stopper and the receiving box is slidably connected in the worm storage cavity. When the receiving box is located in the worm storage cavity, the receiving box is located directly below the rotating plate.

[0012] The present invention is further arranged as follows: A buffer device is arranged in the receiving box. The buffer device includes a buffer plate, a first spring and a second spring. The two ends of the first spring and the second spring are respectively fixed to the bottom surface of the buffer plate and the bottom surface of the junction box. The length of the first spring is greater than the length of the second spring and the first spring is arranged on the side close to the wire passing hole. A pneumatic spray gun is arranged horizontally on the side of the vertical part close to the horizontal part. The spray head of the pneumatic spray gun is aligned with the center of the horizontal part. The pneumatic spray gun is controlled by the control panel and realizes regular spraying.

[0013] The present invention is further arranged as follows: An insecticidal gas storage device is arranged on the box body. The spray head is connected to an external insecticidal gas storage device through a pipeline. A solenoid valve is arranged on the pipeline. The solenoid valve is used to control the spraying of the insecticidal gas and is controlled by the control panel.

[0014] The present invention is further configured such that: a flow sensor is provided between the nozzle and the pipeline, and the flow sensor is used to monitor the flow rate of the insecticidal gas in real time and transmit the flow rate data to the control panel. The control panel controls the opening and closing degree of the solenoid valve according to the flow rate data to achieve precise control of the injection amount of the insecticidal gas.

[0015] The present invention is further configured such that: the stopper is detachably connected to the box body. A plurality of card slots are provided at the bottom of the box body, and a clamping block matching with the card slots is provided on the side wall of the stopper. The stopper is fixed to the box body by inserting the clamping block into the card slots.

[0016] The present invention is further configured such that: an arc groove is provided on the outer wall of the box body, and a sponge cushion block is bonded in the arc groove.

[0017] The present invention is further configured such that: the nozzle includes a main nozzle and a plurality of auxiliary nozzles. The main nozzle is located at the central position of the guiding channel, and the auxiliary nozzles are radially distributed around the main nozzle.

[0018] In summary, the present invention has the following beneficial effects: 1. The infrared probe is used to monitor in real time whether there are flying insects entering, and when flying insects are detected, the insecticidal gas is automatically sprayed. This setting can effectively prevent insects from entering the interior of the box body, avoid problems such as short circuit and corrosion caused by insect activities, and extend the service life of the electric energy metering box. The cooperation of the flow sensor and the control panel can accurately control the injection amount of the insecticidal gas according to actual needs, ensuring both the insect prevention effect and avoiding resource waste. By providing a storage chamber for insects and a rotating plate, the corpses of flying insects can fall into the storage chamber for insects.

[0019] 2. When disassembling the stopper, the operator needs to insert a finger into the guiding channel to block all the infrared probes. According to the system design, when all the infrared probes are blocked, the nozzle will stop spraying the insecticidal gas. This mechanism effectively avoids the operator accidentally coming into contact with the sprayed insecticidal gas during the disassembly process, thus protecting the health and safety of the operator.

[0020] 3. Components such as the stopper and the receiving box are detachably connected, which is convenient for maintenance and replacement. This modular design enables maintenance personnel to quickly replace damaged components, reducing the maintenance time and cost.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0024] For a better description and illustration of the embodiments of the present application, one or more accompanying drawings may be referred to, but the additional details or examples used to describe the drawings should not be considered as limiting the scope of any of the invention creations of the present application, the currently described embodiments or the preferred modes.

[0025] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention, rather than indicating that the device referred to must have a specific orientation or operate in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application in this specification are only for the purpose of describing specific embodiments, and are not intended to limit this application.

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] An electric energy metering box made of PC + ASA material, as Figure 1 shown, includes a box body 1. A wire passing hole 2 is opened at the bottom of the box body 1. A cavity 3 is opened inside the box body 1. A number of components 4 are arranged inside the cavity 3. Specifically, the box body 1 is made of PC + ASA material. The design of the wire passing hole 2 enables wires to enter the inner wall of the box body 1 through the wire passing hole 2 and be connected to the electronic components 4 inside the cavity 3, thereby ensuring the stable operation of the device. At the same time, it can also play a certain role in limiting and protecting the wires, preventing the wires from being messy and scattered. PC itself has high strength and impact resistance, and the addition of ASA further improves the mechanical properties of the material, making the box body 1 made of it have higher strength and impact resistance. At the same time, this material can resist the erosion of a variety of chemical substances, including acids, alkalis, salts, and organic solvents, making the box body 1 made of it applicable to various complex environmental conditions and improving the applicability of the electric energy metering box.

[0029] An insect-proof component is arranged inside the cavity 3 and the insect-proof component is arranged close to the wire passing hole 2. A baffle 5 is arranged directly above the wire passing hole 2 and the baffle 5 is in contact with the edge of the insect-proof component. Specifically, the insect-proof component includes an insect-proof cover 6 and a stop block 7. The insect-proof cover 6 is in contact with the baffle 5. A cavity is formed between the stop block 7 and the insect-proof cover 6 and a spray head 8 is arranged inside the cavity. Three guiding channels 9 are arranged in an array on the stop block 7 and are communicated with the cavity. An infrared probe 10 for real-time monitoring of whether flying insects enter is arranged on the inner wall of each guiding channel 9. A control panel for controlling the opening and closing of the spray head 8 is arranged on the outer wall of the box body 1. When an infrared probe 10 is blocked, the spray head 8 sprays insecticidal gas. When a number of infrared probes 10 are all blocked, the spray head 8 stops spraying. By setting the baffle 5 and the stop block 7, holes matching the wires can be opened on the baffle 5, so as to reduce the gap between the holes and the wires and prevent insects from entering. When flying insects approach the box body 1, they can only enter the guiding channels 9. Immediately, the infrared probe 10 is blocked by the flying insects. At this time, the spray head 8 sprays insecticidal gas to fill the cavity. As the flying insects enter the cavity along the guiding channels 9, they will die when encountering the insecticidal gas, thus preventing the flying insects from entering the cavity 3 and reducing problems such as short circuits and corrosion caused by insect activities, and prolonging the service life of the electric energy metering box. When disassembling the stop block 7, the operator needs to insert a finger into the guiding channels 9 to block all the infrared probes 10. According to the system design, when all the infrared probes 10 are blocked, the spray head 8 will stop spraying insecticidal gas. This mechanism effectively prevents the operator from accidentally contacting the sprayed insecticidal gas during the disassembly process, thus protecting the health and safety of the operator.

[0030] Specifically, the guiding channel 9 includes a vertical portion and a horizontal portion. There are two infrared sensors 10, which are respectively arranged at the connection of the horizontal portion and the vertical portion and on one side of the horizontal portion away from the vertical portion. A guiding surface 12 communicating with the vertical section is provided on the cavity. By arranging two infrared sensors 10, when the flying insects initially enter the guiding channel 9, the nozzle 8 in the cavity starts to spray gas. Thus, when the flying insects gradually enter the cavity, they can immediately be enveloped by the insecticidal gas and killed, improving the insect prevention efficiency. By arranging the guiding surface 12, the killed flying insects slide down along the guiding surface 12, thus avoiding the accumulation of the flying insect corpses in the cavity.

[0031] The nozzle 8 adopts a multi-angle spraying structure. Specifically, the nozzle 8 includes a main nozzle 26 and several auxiliary nozzles 27. The main nozzle 26 is located at the central position of the guiding channel 9. The auxiliary nozzles 27 are radially distributed around the main nozzle 26, and the spraying angle of each auxiliary nozzle is adjustable to adapt to insects of different sizes and flying speeds. The spraying angle of the auxiliary nozzles 27 is adjusted through the control panel. The spraying angle range of the auxiliary nozzles 27 is from 30° to 90° to achieve the efficient killing of fast-flying insects. Since the main nozzle 26 is located at the central position of the guiding channel 9 and is responsible for covering the main area, while the auxiliary nozzles 27 are radially distributed around the main nozzle and can cover a wider range, and the spraying angle of the auxiliary nozzles 27 is adjustable, the spraying direction can be dynamically adjusted according to the size and flying speed of the insects, ensuring that fast-flying insects can also be accurately killed and improving the insecticidal efficiency.

[0032] Further, a rotating plate 13 is provided on one side of the vertical section away from the guiding surface 12. A storage cavity 14 for insects is formed on the stopper 7. The rotating plate 13 is rotatably connected to the opening of the storage cavity 14 and is used to block the storage cavity 14. When the flying insects fall onto the top surface of the rotating plate 13, the rotating plate 13 rotates towards the storage cavity 14. When the flying insects fall into the storage cavity 14, the rotating plate 13 returns to its original position and remains horizontal. By arranging the rotating plate 13, the flying insect corpses will fall onto the top surface of the rotating plate 13 after sliding. At this time, the rotating plate 13 rotates downward and makes the flying insects roll into the storage cavity 14, avoiding the accumulation of the flying insect corpses at the corner. A receiving box 15 is detachably connected to the stopper 7 and the receiving box 15 is slidably connected in the storage cavity 14. When the receiving box 15 is located in the storage cavity 14, the receiving box 15 is located directly below the rotating plate 13. Through the above arrangement, the receiving box 15 is slidably connected in the storage cavity 14 and is located directly below the rotating plate 13, facilitating the rapid disassembly and cleaning by the operator, realizing the rapid disassembly and assembly of the receiving box 15. At the same time, the operator does not need to enter the equipment to clean the flying insect corpses. Only by regularly disassembling the receiving box 15 can the cleaning work be completed, making the maintenance work more efficient and reducing the maintenance time and workload.

[0033] The receiving box 15 is provided with a buffer device. Specifically, the buffer device includes a buffer plate 11, a first spring 23 and a second spring 24. The two ends of the first spring 23 and the second spring 24 are respectively fixed to the bottom surface of the buffer plate 11 and the bottom surface of the junction box. The length of the first spring 23 is greater than that of the second spring 24, and the first spring 23 is arranged closer to the wire passing hole 2. By setting the buffer device, when the flying insects are killed by the insecticidal gas and fall onto the rotating plate 13, the corpses of the flying insects will fall onto the buffer plate 11. At this time, the first spring 23 and the second spring 24 will be compressed and bounce the corpses of the flying insects to the side of the receiving box 15 away from the rotating plate 13. At the same time, due to the fact that the length of the first spring 23 is greater than that of the second spring 24, the buffer ring has a certain inclined surface. When some lighter corpses of flying insects enter the receiving box 15, they will slide down along the inclined surface of the buffer plate 11, thus avoiding secondary pollution or equipment failure caused by corpse accumulation and ensuring the long-term stable operation of the equipment. On the side of the vertical part close to the horizontal part, there is a pneumatic spray gun 25 arranged horizontally. The nozzle 8 of the pneumatic spray gun 25 is aligned with the center of the horizontal part. The pneumatic spray gun 25 is controlled by the control panel and realizes regular spraying. When some smaller mosquitoes enter the horizontal part, they are easily killed earlier, or some flying insects stay in the horizontal part and are killed only when the insecticidal gas enters the horizontal part. As a result, there will be some corpses accumulated in the horizontal part. By setting the pneumatic spray gun 25, it can regularly clean the corpses in the horizontal part and blow them out of the horizontal part, avoiding the accumulation of corpses in the horizontal part and preventing the guide channel 9 from being blocked.

[0034] The box body 1 is provided with an insecticidal gas storage device 16. The nozzle 8 is connected to the external insecticidal gas storage device 16 through a pipeline 18. A solenoid valve 17 is arranged on the pipeline 18. The solenoid valve 17 is used to control the spraying of the insecticidal gas and is controlled by the control panel. The solenoid valve 17 can accurately control the flow rate and spraying time of the insecticidal gas, ensuring that the insecticidal gas can be released in a timely and appropriate amount when flying insects are detected. This not only improves the insecticidal efficiency but also avoids the overuse of the insecticidal gas, reducing resource waste. Moreover, the combination of the solenoid valve 17 and the control panel realizes automatic control, and the insecticidal operation can be completed without manual intervention. Further, a flow sensor is arranged between the nozzle 8 and the pipeline 18. The flow sensor is used to monitor the flow rate of the insecticidal gas in real time and transmit the flow rate data to the control panel. The control panel controls the opening and closing degree of the solenoid valve 17 according to the flow rate data to achieve precise control of the spraying amount of the insecticidal gas. It can judge the size of the flying insects according to the time and range of the infrared probe 10 being blocked, etc., so as to accurately control the spraying amount. Through the above settings, it can be ensured that the amount of insecticidal gas sprayed each time is just right, avoiding resource waste caused by excessive spraying, improving the insecticidal efficiency, and ensuring the best insecticidal effect with the least amount of gas used.

[0035] The stopper 7 is detachably connected to the box body 1. A plurality of card slots 19 are provided at the bottom of the box body 1. A clamping block 20 matching the card slots 19 is provided on the side wall of the stopper 7. The stopper 7 is fixed to the box body 1 by inserting the clamping block 20 into the card slots 19. Since the stopper 7 is fixed by inserting the clamping block 20 into the card slots 19, the disassembly and installation of the stopper 7 are very fast and convenient. Maintenance personnel can complete the operation without using tools, which greatly reduces the maintenance time and workload, improves the maintenance efficiency, and reduces the equipment downtime. At the same time, the detachable connection method makes the stopper 7 an independent module, which can be replaced or upgraded as needed without replacing the entire box body 1.

[0036] An arc groove 21 is provided on the outer wall of the box body 1, and a sponge cushion block 22 is bonded in the arc groove 21. Specifically, the arc groove 21 runs through the top and bottom surfaces of the box body 1. There are two sponge cushion blocks 22 and both are bonded in the arc groove 21. By providing the arc groove 21 and the sponge cushion block 22, when the box body 1 is installed on the electric pole, the arc groove 21 can better adapt to the electric pole, thereby improving the installation stability of the metering box. An alarm device is also provided on the outer wall of the box body 1. When the insecticidal gas storage is insufficient or the system fails, the alarm device emits an audible and visual alarm signal. Through the above settings, it can be ensured that problems can be discovered and processed in time, avoiding equipment damage or safety hazards caused by delayed response.

[0037] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
