Description

Technical Field

[0001] The invention relates to the field of power distribution cabinets, in particular to an intelligent power distribution cabinet for a power transmission and distribution network. Background Art

[0002] The power distribution cabinet is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively dispersed and there are fewer circuits; the motor control center is used in the occasions where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load.

[0003] Due to the influence of buildings, environment, and the location of people living in cities, many distribution cabinets are installed beside the road to help the work of public facilities. Since the distribution cabinets beside the road are set up in the open air, dust is easy to fall on the top. If they are not cleaned in time, the outside of the distribution cabinet will be dirty, affecting the beauty of the city. In poor light conditions, pedestrians and passing vehicles are likely to collide with the distribution cabinet, and the safety of use needs to be improved. In low-lying areas that are prone to water accumulation, or in coastal cities where there is a lot of rain and drainage is not timely, the distribution cabinets beside the road are often flooded and damaged, and the distribution cabinets themselves have no ability to save themselves. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides an intelligent distribution cabinet for a power transmission and distribution network.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] An intelligent power distribution cabinet for a power transmission and distribution network comprises a cabinet body, wherein a cleaning mechanism is installed on the top of the cabinet body, and a protection mechanism is installed on the bottom of the cabinet body.

[0007] The protective mechanism includes an inflatable bag, a fixing plate is installed at the bottom of the cabinet, and a stabilizing mechanism is installed between the fixing plate and the bottom of the cabinet; the top of the inflatable bag is connected to the cabinet, and the bottom is connected to the fixing plate, and an air pump is installed at the bottom of the cabinet, and the air outlet end of the air pump is connected to the air inlet end of the inflatable bag, and a pressure relief valve is arranged on the inflatable bag.

[0008] A start-stop switch for controlling the air pump is installed on one side of the bottom of the cabinet, a magnet plate is installed at the bottom of the start-stop switch, and an iron pressure plate is placed on the upper end of the fixed plate below the start-stop switch. Foam plates are connected to both ends of the pressure plate, and tension springs are connected between the top ends of the pressure plate and the cabinet, so that the pressure plate can press the start-stop switch.

[0009] A cooling cavity is provided on one side of the interior of the cabinet, a storage cavity is provided on the interior of the cooling cavity, a sealing plate is slidably installed on the interior of the storage cavity, a push rod is connected to the bottom of the sealing plate, the bottom end of the push rod passes through the bottom of the cabinet and is fixedly connected to the fixed plate, an overflow port is provided on the upper side of one side of the cabinet, a circulation pipe is provided on the side of the overflow port for the cooling cavity, the bottom of the circulation pipe passes through the bottom of the cabinet and is installed with a first one-way valve, a second one-way valve is installed on the interior of the overflow port, the outlet of the first one-way valve faces the inside of the circulation pipe, and the outlet of the second one-way valve faces the outside of the cabinet.

[0010] Preferably, the stabilizing mechanism includes a stabilizing rod and a sleeve, the top end of the stabilizing rod is inserted into the interior of the sleeve, the stabilizing rod can move up and down inside the sleeve, the top end of the stabilizing rod is connected to a limiting plate, a plurality of shock-absorbing springs are connected between the top of the limiting plate and the inner top end of the sleeve, the bottom end of the stabilizing rod is fixedly connected to the fixing plate, and the top end of the sleeve is connected to the cabinet.

[0011] Preferably, both ends of the top of the fixing plate are connected with pads, and the thickness of the pads is greater than the thickness of the pressing plate.

[0012] Preferably, the cleaning mechanism includes a bracket, a rotating shaft and a scraper. Brackets are welded on both sides of the top of the cabinet. A rotating shaft is rotatably installed between the two brackets. Several scrapers are evenly connected to the outer wall of the rotating shaft. The scraper is made of rubber, and one side of the scraper can contact the top of the cabinet.

[0013] Preferably, a rotation speed sensor is installed at the connection between the bracket and the rotating shaft on one side, and a friction generator is installed at the connection between the bracket and the rotating shaft on the other side.

[0014] Preferably, a plurality of warning lights are installed on the outside of the scraper, the friction generator is electrically connected to a battery, the battery is installed inside the bracket, and the battery is electrically connected to the warning lights.

[0015] Beneficial effects of the present invention:

[0016] 1. By installing the scraper, the gas flow will impact the scraper, which can then drive several scrapers to rotate between the two brackets through the rotating shaft. During the rotation of the scraper, it will contact the top of the cabinet and clean the top of the cabinet, so that the top of the cabinet remains clean. The cabinet is more beautiful and tidy during use, which is conducive to improving the city's image. Dust or other impurities are not easy to accumulate on the top of the cabinet, saving the staff the step of cleaning. In rainy and snowy weather, the scraper can clean the rainwater and snow remaining on the top of the cabinet, so that the rainwater and snow will not cause pressure on the top of the cabinet, and the pressure on the top of the cabinet is smaller. At the same time, the top of the cabinet can be better cleaned with the help of rainwater and snow.

[0017] 2. By installing a warning light on the scraper, the speed sensor at one end can measure the speed of the shaft during the rotation of the shaft, so that the staff can know the wind force the cabinet is subjected to in time. The electric energy generated by the friction generator provides power supply for the warning light, so that the warning light can emit light normally. At night or in poor visibility, it can serve as a warning for passing vehicles and pedestrians to prevent pedestrians and vehicles from hitting the cabinet, which can not only improve the safety of the cabinet in use, but also protect the safety of passing vehicles and pedestrians. It saves the cost of installing other warning objects and can serve as a warning mark while cleaning the cabinet.

[0018] 3. By setting up an inflatable bag, if heavy rain or other reasons for water accumulation occur during use, the bottom of the cabinet will accumulate water deeply. As the depth of the water accumulates, the pressure plate continues to move upward, and finally the pressure plate contacts the magnet plate. Under the pull of the tension spring, the pressure plate presses the magnet plate, so that the start-stop switch is pressed and the air pump starts to work. The air pump fills gas into the interior of the inflatable bag, causing the volume of the inflatable bag to increase and expand. The inflatable bag then lifts the cabinet upward, and the height of the cabinet rises, making it difficult for the accumulated water below to enter the interior of the cabinet, and the lines inside the cabinet are not easy to come into contact with water. The cabinet can achieve self-rescue in the state of water accumulation, and can be used in low-lying installation locations that are prone to water accumulation, or in coastal cities where there is a lot of rain and drainage is not timely.

[0019] 4. By setting up a cooling chamber, the water at the bottom of the cabinet can enter the cooling chamber when the cabinet moves upward. After the water enters the cooling chamber, it can cool the cabinet to prevent the various parts inside the cabinet from overheating during operation. It can also reduce the accumulation of water at the bottom of the cabinet, making it less likely for the cabinet to be submerged by the accumulated water. When the cabinet descends, the sealing plate moves upward inside the storage chamber and discharges part of the water in the cooling chamber through the overflow port, which ensures that the cabinet can be cooled normally and leaves part of the cooling chamber free for subsequent water storage. The cabinet is raised and water is absorbed simultaneously, which cooperates with each other and can improve the safety of the cabinet during use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The technical scheme of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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 are within the scope of protection of the present invention.

[0028] See also Figure 1-5 As shown, an intelligent distribution cabinet for a power transmission and distribution network comprises a cabinet body 1, a cleaning mechanism is installed on the top of the cabinet body 1, and a protective mechanism is installed on the bottom.

[0030] A start-stop switch 13 for controlling the air pump is installed on one side of the bottom of the cabinet 1, a magnet plate 12 is installed at the bottom of the start-stop switch 13, and an iron pressure plate 15 is placed on the upper end of the fixed plate 4 below the start-stop switch 13, both ends of the pressure plate 15 are connected to foam plates 16, and tension springs 14 are connected between the top ends of the pressure plate 15 and the cabinet 1, so that the pressure plate 15 can press the start-stop switch 13.

[0031] A cooling chamber 20 is provided on one side of the interior of the cabinet 1, a storage chamber 21 is provided on the interior of the cooling chamber 20, a sealing plate 26 is slidably installed on the interior of the storage chamber 21, a push rod 22 is connected to the bottom of the sealing plate 26, the bottom end of the push rod 22 passes through the bottom of the cabinet 1 and is fixedly connected to the fixing plate 4, an overflow port 25 is provided on the upper side of one side of the cabinet 1, a circulation pipe 24 is provided on the side of the overflow port 25 of the cooling chamber 20, the bottom of the circulation pipe 24 passes through the bottom of the cabinet 1 and is installed with a first one-way valve 23, a second one-way valve is installed on the interior of the overflow port 25, the outlet of the first one-way valve 23 faces the inside of the circulation pipe 24, and the outlet of the second one-way valve faces the outside of the cabinet 1.

[0032] As a technical optimization scheme of the present invention, the stabilizing mechanism includes a stabilizing rod 5 and a sleeve 19. The top end of the stabilizing rod 5 is inserted into the interior of the sleeve 19, and the stabilizing rod 5 can move up and down inside the sleeve 19. The top end of the stabilizing rod 5 is connected to a limiting plate 18. A plurality of shock-absorbing springs 17 are connected between the top of the limiting plate 18 and the inner top end of the sleeve 19. The bottom end of the stabilizing rod 5 is fixedly connected to the fixing plate 4, and the top end of the sleeve 19 is connected to the cabinet 1. During the up and down movement of the cabinet 1, the stabilizing rod 5 moves inside the sleeve 19, thereby limiting the movement of the cabinet 1, so that the cabinet 1 is more stable during the movement and is not prone to shaking.

[0033] As a technical optimization solution of the present invention, both ends of the top of the fixing plate 4 are connected with pads 3, the thickness of the pads 3 is greater than the thickness of the pressing plate 15, and the pads 3 can prevent the cabinet body 1 from squeezing the pressing plate 15, so that the pressing plate 15 has space to rise.

[0034] As a technical optimization solution of the present invention, the cleaning mechanism includes a bracket 8, a rotating shaft 10 and a scraper 7. Brackets 8 are welded on both sides of the top of the cabinet 1. A rotating shaft 10 is rotatably installed between the two brackets 8. The outer wall of the rotating shaft 10 is evenly connected with a plurality of scrapers 7. The scraper 7 is made of rubber. One side of the scraper 7 can contact the top of the cabinet 1. After the rotating shaft 10 rotates, it can drive the scraper 7 to scrape and clean the top of the cabinet 1.

[0035] As a technical optimization solution of the present invention, a speed sensor 9 is installed at the connection between the bracket 8 and the rotating shaft 10 on one side, and a friction generator 11 is installed at the connection between the bracket 8 and the rotating shaft 10 on the other side. The speed sensor 9 can measure the rotation speed of the rotating shaft 10, and the rotating shaft 10 can generate electricity through the friction generator 11 after rotating.

[0036] As a technical optimization solution of the present invention, a plurality of warning lights 6 are installed on the outside of the scraper 7, the friction generator 11 is electrically connected to the battery, the battery is installed inside the bracket 8, the battery is electrically connected to the warning light 6, and the warning light 6 has the function of warning pedestrians and vehicles when it is working.

[0037] When the present invention is in use, the cabinet 1 is moved to a position where it needs to be installed, the fixing plate 4 is fixedly installed on the ground where it needs to be installed, the wires enter the interior of the cabinet 1 for normal connection and installation, and ensure that the cabinet 1 can move up and down above the fixing plate 4.

[0038] The gas flow impacts the scraper 7, which in turn drives several scrapers 7 to rotate between the two brackets 8 through the rotating shaft 10. The scraper 7 contacts the top of the cabinet 1 during rotation, and then cleans the top of the cabinet 1, so that the top of the cabinet 1 remains clean, and the cabinet 1 is more beautiful and tidy during use, which is conducive to the improvement of the city's image. It makes it difficult for dust or other impurities to accumulate on the top of the cabinet 1, saving the staff the step of cleaning. If it is rainy or snowy, the scraper 7 can clean the rainwater and snow remaining on the top of the cabinet 1, so that the rainwater and snow will not cause pressure on the top of the cabinet 1, and the pressure on the top of the cabinet 1 is smaller. At the same time, the top of the cabinet 1 can be better cleaned with the help of rainwater and snow.

[0039] During the rotation of the shaft 10, the speed sensor 9 at one end measures the speed of the shaft 10, and the measured speed value is transmitted to the intelligent signal receiving end carried by the cabinet 1 itself, and finally transmitted to the background control center, so that the staff can know the wind force borne by the cabinet 1 in time. The friction generator 11 at the other end works under the friction of the shaft 10, and the electricity generated by the friction generator 11 is transmitted to the inside of the battery for storage. The battery provides power supply for the warning light 6 on the scraper 7, so that the warning light 6 can emit light normally, and at night or in the case of poor visibility, it can serve as a warning for passing vehicles and pedestrians to prevent pedestrians and vehicles from hitting the cabinet 1, which can not only improve the safety of the cabinet 1 in use, but also protect the safety of passing vehicles and pedestrians. It saves the cost of installing other warning objects and can serve as a warning mark while cleaning the cabinet 1.

[0040] If heavy rain or other reasons for water accumulation occur, the bottom of the cabinet 1 will accumulate deep water. After water accumulates at the bottom of the cabinet 1, the foam board 16 and the pressure plate 15 are in contact with the water and are affected by the buoyancy of the water. The downward tension of the tension spring 14 is reduced, and then the tension spring 14 pulls the pressure plate 15 upward. As the depth of the water accumulation increases, the pressure plate 15 continues to move upward, and the magnetic force of the upper magnet plate 12 on the pressure plate 15 gradually increases. Finally, the pressure plate 15 contacts the magnet plate 12. Under the pull of the tension spring 14, the pressure plate 15 presses the magnet plate 12, so that the start-stop switch 13 is pressed, and the air pump starts to operate. The air pump fills the air bag 2 with gas, so that the volume of the air bag 2 increases and expands. Then the air bag 2 lifts the cabinet 1 upward, and the height of the cabinet 1 increases, making it difficult for the accumulated water below to enter the interior of the cabinet 1, and the circuit inside the cabinet 1 is not easy to contact with water. The cabinet 1 can realize self-rescue in the case of water accumulation, and can be used in low-lying installation locations that are prone to water accumulation, or in coastal cities where there is a lot of rain and drainage is not timely. When the pressure of the gas inside the inflatable bag 2 reaches a preset value, the gas is discharged from the pressure relief valve, and the inflatable bag 2 is not easily damaged, and the cabinet 1 will not fall down. After the water accumulation is eliminated, the staff pulls the pressure plate 15 downward, the air pump stops working, and the cabinet 1 can be lowered back to its original position.

[0041] During the upward and downward movement of the cabinet 1, the stabilizing rod 5 moves inside the sleeve 19, thereby limiting the movement of the cabinet 1, making the cabinet 1 more stable and less prone to shaking during the movement. The damping spring 17 buffers the movement of the cabinet 1 to prevent it from shaking.

[0042] During the upward movement of the cabinet 1, the sealing plate 26 moves downward inside the storage chamber 21, thereby increasing the space inside the cooling chamber 20, reducing the air pressure inside the cooling chamber 20, and the water at the bottom of the cabinet 1 enters the inside of the circulation pipe 24 from the first one-way valve 23, and then enters the inside of the cooling chamber 20. After the water enters the inside of the cooling chamber 20, it can not only cool the cabinet 1, but also prevent the various parts inside the cabinet 1 from overheating during operation. It can also reduce the water accumulation at the bottom of the cabinet 1, making it difficult for the cabinet 1 to be submerged by the accumulated water. When the cabinet 1 descends, the sealing plate 26 moves upward inside the storage chamber 21, and discharges part of the water in the cooling chamber 20 through the overflow port 25, which not only ensures that the cabinet 1 can be cooled normally, but also leaves part of the cooling chamber 20 free for subsequent water storage. The cabinet 1 is raised and absorbs water at the same time, which cooperates with each other and can improve the safety of the cabinet 1 in use.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.
