Description

Technical Field

[0001] The present application relates to the technical field of flood control equipment, and in particular to an early warning device for preventing waterlogging in a substation. Background Art

[0002] In modern society, the stability of power supply is crucial for industrial production, residential life, and other fields. Substations, as key hubs in the power system, are directly related to the reliability of the entire power grid. However, the normal operation of substations is often threatened by natural disasters. In particular, flooding, due to its suddenness and destructiveness, poses a serious threat to the safe operation of substations.

[0003] Existing flood warning systems are effective in normal weather conditions, but they exhibit significant flaws in severe weather conditions such as heavy snow and hail. Hail, in particular, exerts a powerful impact, easily damaging key components such as solar panels and ultrasonic water level gauges, rendering the warning system ineffective. In severe weather, the failure of these warning systems makes it difficult for personnel to detect abnormal water levels and implement flood control and drainage measures in a timely manner. This can cause electrical equipment within the station to become flooded, leading to short circuits, tripping, and other accidents, resulting in widespread power outages and disrupting normal social operations. Furthermore, prolonged flooding can cause permanent damage to equipment, resulting in significant economic losses.

[0072] Base plate 1, vertical shell 2, bracket 3, monitoring component, protection mechanism and adjustment mechanism.

[0073] The vertical shell 2 is installed on the base plate 1; the bracket 3 is installed on the vertical shell 2 for supporting the monitoring component; the monitoring component includes a water level monitoring module, a data collector 7, a wireless communication module 8, a power module and an alarm module.

[0077] The protective mechanism is installed on the vertical shell 2 and the installation box 30, which can effectively protect the ultrasonic water level meter 4, LED display screen 5, alarm speaker 26 and alarm light 27, and prevent these key components from being damaged by external forces in severe weather such as heavy snow and hail, thereby significantly improving the reliability of the device in severe weather and solving the problem that key components of the existing device are easily damaged by external forces, resulting in device failure; the solar photovoltaic panel 9 is adjustable in angle and is arranged on the vertical shell 2 through an adjustment mechanism.

[0079] The above is the first embodiment of a substation anti-waterlogging early warning device provided by the embodiment of the present application. The following is the second embodiment of a substation anti-waterlogging early warning device provided by the embodiment of the present application. For details, please refer to Figures 1 to 10 .

[0080] Based on the solution of the above embodiment 1:

[0081] Furthermore, the protective mechanism includes: a screw 12 assembled in the mounting box 30 through a bearing, the bottom end of the screw 12 extends into the vertical shell 2; an adjusting frame 13 threadedly mounted on the screw 12, and a first protective shell 10 and a second protective shell 11 are fixed on the adjusting frame 13, the first protective shell 10 is used to shield and protect the ultrasonic water level meter 4 and the LED display screen 5, and the second protective shell 11 is used to shield and protect the solar photovoltaic panel 9; a motor 24 fixed in the mounting box 30, the output shaft of the motor 24 is fixedly connected to the screw 12 through a coupling; a second tooth plate 28 slidably mounted on the mounting box 30; a second gear 29 fixed on the output shaft of the motor 24, the second gear 29 is engaged with the second tooth plate 28; a third protective shell 32 assembled on the second tooth plate 28 through a connecting plate 31, the third protective shell 32 is used to shield and protect the alarm horn 26 and the alarm light 27; and a meteorological sensor 41 arranged on the bracket 3.

[0082] In the above design, once meteorological sensors around the substation detect a severe weather signal, they quickly transmit the signal to the controller inside the installation box 30. Upon receiving the signal, the controller immediately activates the motor 24. The output shaft of the motor 24 rotates the screw 12 via a coupling. Because the screw 12 is mounted within the installation box 30 via a bearing, with its bottom end extending into the vertical housing 2, the rotation of the screw 12 drives the adjustment bracket 13, threadedly mounted thereon, downward along the screw 12. As the adjustment bracket 13 descends, the first and second protective shells 10, 11 affixed thereto, also descend accordingly. The first protective shell 10 precisely moves to cover the ultrasonic water level gauge 4 and LED display 5, providing comprehensive shielding and protection. The second protective shell 11, in turn, covers the folded solar photovoltaic panel 9, ensuring its proper protection. Simultaneously, the second gear 29 on the output shaft of the motor 24 rotates with the shaft, meshing with the second toothed plate 28, which is slidably mounted within the installation box 30, pushing the second toothed plate 28 to slide. The third protective shell 32 assembled on the second tooth plate 28 through the connecting plate 31 will also move accordingly, and eventually cover the alarm speaker 26 and the alarm light 27 to provide shielding protection for them.

[0083] The first protective housing 10, second protective housing 11, and third protective housing 32 each perform their respective functions, specifically protecting the ultrasonic water level gauge 4, LED display 5, folded solar photovoltaic panel 9, alarm horn 26, and alarm light 27. This precise protective design effectively prevents key components from being directly impacted by external forces in severe weather conditions such as heavy snow and hail, ensuring the safety of each functional module of the device and maintaining its normal operation.

[0084] Motor 24, the power source of the entire protective mechanism, utilizes two different transmission methods to coordinate the operation of the various protective shells. Firstly, the threaded drive between screw 12 and adjustment frame 13 precisely controls the lowering of first and second protective shells 10, 11. Secondly, the meshing drive between second gear 29 and second toothed plate 28 propels the sliding movement of third protective shell 32. Each protective shell can quickly deploy and protect multiple key components, significantly improving protection efficiency.

[0085] Furthermore, the adjustment mechanism includes: a mounting frame 14 fixed to one side of the vertical shell 2, with a first rotating rod 15 assembled on the mounting frame 14 through a bearing; an assembly plate 16 fixed on the first rotating rod 15 for carrying the solar photovoltaic panel 9; a first transmission rod 17 assembled on the vertical shell 2 through a bearing; a first bevel tooth 18 and a second bevel tooth 25 respectively fixed on the first transmission rod 17 and the first rotating rod 15, the first bevel tooth 18 and the second bevel tooth 25 being engaged for transmission; a first tooth plate 19 fixed on the adjustment frame 13; and a first gear 20 assembled on the first transmission rod 17, the first gear 20 being engaged with the first tooth plate 19.

[0086] In this design, when meteorological sensors around the substation detect severe weather, the signal is rapidly transmitted to a controller within the mounting box 30. The controller immediately activates the motor 24, whose output shaft, via a coupling, rotates the screw 12. Because the screw 12 is mounted within the mounting box 30 via a bearing and its bottom end extends into the vertical housing 2, its rotation drives the adjustment frame 13, threadedly mounted thereon, downward along the screw 12. As the adjustment frame 13 descends, the first and second protective shells 10, 11 affixed thereto, descend simultaneously. The first protective shell 10 precisely covers the ultrasonic water level gauge 4 and LED display 5, while the second protective shell 11 covers the folded solar photovoltaic panel 9. Simultaneously, the second gear 29 on the output shaft of the motor 24 rotates with the shaft, meshing with the second toothed plate 28 slidably mounted within the mounting box 30. This drives the second toothed plate 28 to slide, causing the third protective shell 32, mounted on the second toothed plate 28 via a connecting plate 31, to move to the position of the alarm horn 26 and warning light 27, shielding them from view.

[0087] During this process, the movement of the adjustment frame 13 also triggers the operation of the adjustment mechanism. The first toothed plate 19 on the adjustment frame 13 moves synchronously with the adjustment frame 13, driving the first gear 20 meshing with it to rotate. Since the first gear 20 is mounted on the first transmission rod 17, and the first transmission rod 17 is mounted on the vertical shell 2 through a bearing, the first transmission rod 17 rotates with the first gear 20. The first bevel gear 18 fixed on the first transmission rod 17 drives the second bevel gear 25 meshing with it and fixed on the first rotating rod 15 to rotate. The first rotating rod 15 is mounted on the mounting frame 14 through a bearing, and the mounting frame 14 is fixed to one side of the vertical shell 2. Finally, the rotation of the first rotating rod 15 causes the assembly plate 16 supporting the solar photovoltaic panel 9 to rotate, thereby folding the solar photovoltaic panel 9. Before the arrival of bad weather, the protection mechanism operates to lower the adjustment frame 13, synchronously driving the adjustment mechanism to fold the solar photovoltaic panel 9 to a suitable protection angle; when the weather is good, the solar photovoltaic panel 9 can also be flexibly adjusted to unfold through the adjustment mechanism according to actual needs to obtain the best light;

[0088] The first protective shell 10, second protective shell 11, and third protective shell 32 each perform their respective functions, specifically protecting the ultrasonic water level gauge 4, LED display 5, folded solar photovoltaic panel 9, alarm horn 26, and alarm light 27. This precise protective design effectively prevents key components from being directly impacted by external forces in inclement weather such as heavy snow and hail, effectively ensuring the safety of each functional module of the device and maintaining its normal operation. Furthermore, the linkage between the adjustment mechanism and the protective mechanism allows the solar photovoltaic panel 9 to automatically fold in inclement weather and be effectively shielded by the second protective shell 11, further improving the protection system for key components.

[0089] The motor 24 serves as the power core of the entire protective mechanism, and realizes the coordinated operation of each protective shell through two different transmission methods. On the one hand, with the help of the threaded transmission of the screw 12 and the adjustment frame 13, the descending action of the first protective shell 10 and the second protective shell 11 is precisely controlled; on the other hand, the meshing transmission of the second gear 29 and the second tooth plate 28 is used to drive the third protective shell 32 to slide. More importantly, the movement of the adjustment frame 13 cleverly links the adjustment mechanism. When the protective mechanism is started, the adjustment mechanism responds quickly and automatically adjusts the solar photovoltaic panel 9 to the protection angle. The protection adjustment of each protective shell and the solar photovoltaic panel 9 can be completed quickly in a short time, which greatly improves the protection efficiency and gains valuable time for dealing with severe weather.

[0090] The screw 12 is assembled in the mounting box 30 via a bearing, ensuring its stability during rotation. The threaded connection between the adjustment frame 13 and the screw 12, as well as the fixing method of each protective shell to the adjustment frame 13 and the second tooth plate 28, together form a solid structural system. The various components of the adjustment mechanism, such as the first rotating rod 15 and the first transmission rod 17, are connected through bearing assembly, bevel gear meshing, etc., and are also stable and reliable. This enables the entire protection and adjustment mechanism to withstand a certain intensity of external impact during operation, making it less susceptible to damage, effectively extending the service life of the mechanism and reducing maintenance costs.

[0091] Furthermore, a guide groove 22 is fixed on one side of the vertical shell 2 ; a slider 23 is slidably installed in the guide groove 22 ; a support rod 21 is hinged on the slider 23 ; and the top end of the support rod 21 is hinged to the assembly plate 16 .

[0092] In the above design, when the adjustment mechanism adjusts the angle of the solar photovoltaic panel 9, the assembly plate 16 rotates with the first rotating rod 15. Because the top end of the support rod 21 is hinged to the assembly plate 16, the support rod 21 swings around its hinge point with the assembly plate 16 during its rotation. Simultaneously, the lower end of the support rod 21 is hinged to a slider 23, which slides within a guide groove 22 fixed to one side of the vertical housing 2. As the support rod 21 swings, the slider 23 slides up and down within the guide groove 22 accordingly. When inclement weather arrives, the protective mechanism activates, causing the adjustment frame 13 to descend. As the adjustment mechanism simultaneously adjusts the solar photovoltaic panel 9 to the protective angle, the support rod 21, slider 23, and guide groove 22 work together to ensure that the assembly plate 16 and solar photovoltaic panel 9 rotate smoothly to the appropriate protective position. In normal weather, when adjusting the angle of the solar photovoltaic panel 9 according to the required light angle, this coordinated action ensures that the solar photovoltaic panel 9 can rotate accurately and smoothly to the desired angle.

[0093] Furthermore, both the first protective shell 10 and the third protective shell 32 are provided with observation ports; visualization glass windows 33 are provided in the observation ports.

[0094] In the above design, during daily operation and inclement weather protection, the observation ports on the first and third protective shells 10 and 32 and the visual glass windows 33 provided therein function. Workers can use these observation ports and the visual glass windows 33 to inspect the protected components. For example, when the protective mechanism is activated, the first protective shell 10 blocks the ultrasonic water level gauge 4 and the LED display 5. Without opening the protective shell, workers can directly observe the working status of the ultrasonic water level gauge 4 through the observation ports, such as whether the values ​​on the display are jumping normally, to determine whether water level monitoring is proceeding normally. They can also check whether the LED display 5 has any abnormal display and understand whether the warning information is being presented normally. With respect to the third protective shell 32, after blocking the alarm horn 26 and the alarm light 27, workers can use the observation ports and the visual glass windows 33 to check whether the alarm horn 26 is physically damaged and whether the alarm light 27 is illuminated normally when the warning is triggered, thereby ensuring the normal operation of the alarm module.

[0095] Furthermore, a through slot is provided on the vertical shell 2 for the adjustment frame 13 to move; and a shielding plate 39 is assembled on the vertical shell 2 by means of bolts.

[0096] In the above design, the through slots in the vertical housing 2 provide space for the adjustment frame 13 to move. When the protective mechanism is activated, the motor 24 drives the screw 12 to rotate, and the adjustment frame 13, driven by the screw 12, moves up and down the vertical housing 2 through the through slots. The shielding plate 39 is removable to facilitate inspection and maintenance of the components.

[0097] Furthermore, a cleaning mechanism for cleaning the LED display screen 5 is provided in the vertical shell 2, and the cleaning mechanism includes: a second rotating rod 34 assembled on the vertical shell 2 through a bearing, and a cleaning brush 35 is fixed on the second rotating rod 34; a second transmission rod 36 assembled in the vertical shell 2 through a bearing, and the top end of the second transmission rod 36 is fixedly connected to the screw 12 through a coupling; and third bevel teeth 37 respectively fixed on the second transmission rod 36 and the second rotating rod 34 and meshing with each other.

[0098] In the above design, when the protective mechanism is activated, the motor 24 drives the screw 12 to rotate, and the cleaning mechanism also operates synchronously. Because the top end of the second transmission rod 36 is fixedly connected to the screw 12 via a coupling, the rotation of the screw 12 drives the second transmission rod 36 to rotate along with it. A third bevel gear 37 is fixed to the second transmission rod 36, and another third bevel gear 37 that meshes with it is fixed to the second rotating rod 34. The second rotating rod 34 is assembled to the vertical housing 2 via a bearing. When the second transmission rod 36 rotates, the third bevel gear 37 on it drives the third bevel gear 37 on the second rotating rod 34 that meshes with it to rotate, thereby rotating the second rotating rod 34. Because the cleaning brush 35 is fixed to the second rotating rod 34, the rotation of the second rotating rod 34 drives the cleaning brush 35 to rotate, cleaning the LED display 5. For example, during the operation of the protective mechanism, as the adjustment frame 13 moves up and down, the cleaning brush 35 continuously rotates, cleaning the surface of the LED display 5 and removing dust.

[0099] Furthermore, a limit block is provided on the second tooth plate 28 ; and a through opening for the second tooth plate 28 to slide is opened on the installation box 30 .

[0100] In the above design, the cooperation between the stop block and the through hole enables the sliding position of the second slotted plate 28 to be precisely controlled, thereby ensuring that the third protective shell 32 can accurately move to the predetermined position during each protective and release operation.

[0101] Furthermore, a detachable inspection panel is provided on the installation box 30; the inspection panel is fixedly connected to the installation box 30 by screws; and an assembly hole is provided on the base plate 1.

[0102] In the above design, for the removable baffle on the installation box 30, when it is necessary to inspect, maintain or install new components inside the installation box 30, the staff can use a screwdriver or other tools to unscrew the screws connecting the baffle and the installation box 30, and remove the baffle from the installation box 30, thereby opening the internal space of the installation box 30, making it convenient to operate the internal motor 24, the second tooth plate 28, the second gear 29 and other components. After the operation is completed, the baffle is put back in place and re-fixed to the installation box 30 with screws to restore the closed state of the installation box 30. The assembly holes on the base plate 1 are used to install the entire early warning device to the specified position. During installation, the base plate 1 is fixed to the ground of the substation or other installation platform by passing connecting parts such as bolts and nuts through the assembly holes to ensure the stability and safety of the early warning device.

[0103] Furthermore, a ball bearing 40 is mounted on the slider 23 ; the ball bearing 40 contacts the inner wall of the guide groove 22 .

[0104] In the above design, the presence of balls 40 converts sliding friction between slider 23 and guide groove 22 into rolling friction. Compared to sliding friction, rolling friction significantly reduces resistance, allowing slider 23 to move more smoothly within guide groove 22. This not only reduces the power required to drive slider 23, lowering energy consumption, but also improves the responsiveness of the adjustment mechanism.

[0105] In general, the early warning device designed in this application uses a water level monitoring module, including an ultrasonic water level meter 4, a data collector 7, and a wireless communication module 8 to monitor water level data in real time and transmit it in a timely manner. The alarm module, LED display 5, alarm speaker 26, and alarm light 27 provide accurate early warnings when the water level is abnormal, so that staff can take precautions against flooding and drainage in advance, effectively reducing the risk of electrical equipment in the station being soaked in water, and ensuring social operation. The protective mechanism effectively protects key components and greatly improves the reliability of the device in severe weather. The adjustment mechanism is linked to the protective mechanism to achieve flexible adjustment of the angle of the solar photovoltaic panel 9, improve power generation efficiency in normal weather, and automatically fold for protection in severe weather. The observation port and visual glass window 33 make it convenient for staff to check the status of components in real time. The design of the through groove, baffle 39, detachable baffle and assembly hole facilitates maintenance and installation of the device. The ball 40 reduces friction resistance and improves adjustment efficiency.
