Description

Technical Field

[0001] This invention relates to the field of moisture-proof technology for water conservancy pumping stations, and in particular to a moisture-proof structure for electrical automation equipment in water conservancy pumping stations. Background Technology

[0002] In the engineering system of modern water conservancy projects, pumping stations occupy an irreplaceable core position, much like the heart of the human circulatory system, continuously injecting vitality into the entire water network. Driven by powerful engines, pumping stations undertake the crucial task of water resource allocation. Based on the water usage and diversion needs of different regions and time periods, they skillfully and precisely deliver water resources from abundant water sources to water-scarce areas. Furthermore, pumping stations can promptly discharge urban stormwater into rivers and seas, effectively alleviating urban flooding problems. For example, multi-pumping station water diversion projects, through scientific scheduling, ensure the rational allocation of water resources and water supply security, while improving project operational efficiency and ensuring project safety and stability. These pumping stations not only handle industrial, agricultural, and residential water use but also possess flood control and drainage functions. With the increasing importance of ecological civilization construction, pumping stations also play a role in protecting and improving river water quality.

[0003] Engineers have continuously optimized the control and operation of water pumping stations, but slow response and cumbersome processes still exist in areas such as pump start-up and shutdown protection and water level regulation. With the advancement of new technologies, electrical automation equipment, once put into use, can achieve rapid automatic start-up and shutdown. However, due to the proximity of the electrical equipment's working area to water, the air humidity makes the equipment susceptible to moisture. When the electrical automation equipment itself generates heat, resulting in a high internal temperature compared to the external temperature, moisture easily forms water droplets on the cooler inner walls of the cabinet. If not cleaned promptly, water will seep into the insulation material, causing moisture damage to electrical components, significantly reducing insulation resistance, and potentially leading to leakage. Simultaneously, water droplets on the circuit boards can form conductive paths between component pins, causing short circuits and potentially burning out the circuit boards, affecting the control functions of the automation system. Furthermore, the cabinets, being exposed to the outside air, are prone to dust accumulation, hindering moisture drainage. This patent provides a moisture-proof structure for electrical automation equipment in water pumping stations to alleviate the aforementioned technical problems in the existing technology. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as moisture entering the cabinet and easily forming water droplets on the cool inner wall of the cabinet. If not cleaned, moisture may seep into the insulating materials, causing electrical wire insulation to become damp, resulting in a significant decrease in insulation resistance and potential leakage. On circuit boards, water droplets can form conductive paths between component pins, causing short circuits and circuit board malfunctions, thus affecting the control functions of the automation system. Furthermore, since the cabinet is located in the outside air, dust can easily accumulate, hindering the outflow of moisture. Therefore, this invention proposes a moisture-proof structure for electrical automation equipment in water conservancy pumping stations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A moisture-proof structure for electrical automation equipment in a water conservancy pumping station includes an outer cabinet and an inner cabinet. The inner cabinet is rotatably connected to a third threaded rod, which is threadedly connected to a heat dissipation strip. The third threaded rod is driven by a second threaded rod, which is threadedly connected to a square cleaning strip. The bottom of the second threaded rod allows observation of the outer cabinet, which is connected to a half-gear. The half-gear intermittently meshes with a first rack and a second rack, respectively. Both the first and second racks are located on the inner wall of an elliptical ring. The side of the elliptical ring is provided with a sweeping strip for cleaning the mesh. The half-gear is driven by a second bevel gear, which meshes with a first bevel gear. A connecting rod is fixedly connected to the side of the first bevel gear, and the connecting rod is driven by a first threaded rod. The first threaded rod is threaded with a fixing block, and a sponge block is fixedly connected to the side of the fixing block. The inner cabinet contains a heat dissipation mechanism for heat dissipation.

[0006] The above technical solution further includes: The heat dissipation mechanism includes an inert gas storage chamber disposed in the inner cabinet. A sliding column is slidably connected inside the inert gas storage chamber. An L-shaped baffle is fixedly connected above the sliding column. A spring is fixedly connected to the bottom of the L-shaped baffle. The side of the spring away from the L-shaped baffle is fixedly connected to the bottom of the inner cabinet. A first belt is driven by a third threaded rod. A second threaded rod is driven by a second bevel gear. A half-gear is driven by a second bevel gear. A second belt is driven by a connecting rod. A first threaded rod is driven by a connecting rod.

[0007] A rotating plate is rotatably connected to the side of the outer cabinet, and a solar panel is installed on the top of the outer cabinet.

[0008] The bottom of the outer cabinet is provided with a ramp for water droplet flow, and the bottom of the outer cabinet is provided with a square groove for placing the mesh.

[0009] The inner cabinet has a square opening on its side for heat dissipation.

[0010] The first threaded rod is internally connected to the outer cabinet for rotation.

[0011] The inner cabinet is provided with a wide groove for the first belt to drive the transmission.

[0012] The second bevel gear is rotatably connected to the bottom of the outer cabinet. A narrow support block is provided on the side of the first bevel gear. This rotatable connection between the second bevel gear and the bottom of the outer cabinet creates a stable connection point for power transmission, ensuring the second bevel gear maintains a stable axial position during rotation and effectively preventing power loss and component wear caused by shaking. The narrow support block on the side of the first bevel gear further enhances its stability during operation. The stable operation of the two bevel gears ensures that the power transmitted from the half-gear can be efficiently and accurately transmitted through the second and first bevel gears to the connecting rod, driving the subsequent component movements.

[0013] The outer cabinet is equipped with multiple sets of round legs at its bottom for support. These legs significantly enhance the stability of the cabinet. In the complex working environment of a water pumping station, uneven ground may exist; the multiple sets of round legs can evenly distribute the weight of the cabinet, adapting to different ground conditions and preventing the cabinet from tilting or even toppling due to uneven stress. Stable cabinet placement provides a fundamental guarantee for the normal operation of the internal electrical automation equipment and moisture-proof structure, preventing damage to equipment components or changes in the relative positions of the moisture-proof structure components due to cabinet shaking, thus ensuring the effectiveness of the moisture-proof function.

[0014] The bottom of the third threaded rod is fixedly connected to the output end of the motor inside its inner cabinet. This connection ensures that the power generated by the motor can be directly and efficiently transmitted to the third threaded rod. After the motor starts, the rotational speed and direction of the third threaded rod can be precisely controlled, thereby driving the heat dissipation fins to move stably up and down along the inner wall of the outer cabinet. The stable movement of the heat dissipation fins effectively regulates the airflow inside the outer cabinet, expelling hot air and reducing moisture condensation. Furthermore, it drives the operation of other components, such as using the first belt to rotate the second threaded rod to remove water droplets, playing a crucial role in maintaining a good operating environment for the equipment and achieving moisture-proof functionality.

[0015] The present invention has the following beneficial effects: 1. In this invention, a humidity sensor monitors the humidity inside the cabinet in real time. When the humidity exceeds the standard, the bottom motor is quickly activated to accelerate internal air convection, blowing hot air towards the side openings to reduce water vapor condensation. Humidity changes are also related to the internal gas state. On sunny days, the heat generated by the equipment causes the gas to expand, promoting heat dissipation. On rainy days, abnormal humidity causes the equipment's operation to affect the gas thermal environment. This invention ensures that gas expansion, heat dissipation, and moisture prevention work in tandem. At the same time, it promotes drainage, and the side sponge blocks clean water droplets from the top, preventing moisture from seeping into the insulation material, eliminating leakage and short circuit faults, ensuring the stable operation of automation functions, and improving the working efficiency of the water pumping station. 2. In this invention, considering the high humidity and large temperature difference between the interior and exterior of electrical automation equipment operating environments, where moisture easily condenses and damages the equipment, this structure exhibits superior intelligent moisture-proof performance. A humidity sensor monitors in real time, triggering an early warning system that activates the entire moisture-proof cleaning system. The internal gas expansion and contraction dynamically adjusts with temperature and humidity, working in conjunction with the moisture-proof components. The automatic monitoring and cleaning mechanism not only prevents moisture but also automatically cleans the bottom mesh of the cabinet, preventing dust blockage and drainage issues. It also avoids water droplets mixing with dust, which could corrode metal components and interfere with the performance of electronic components. Attached Figure Description

The half-gear 22 intermittently meshes with a first rack 23 and a second rack 24. The first rack 23 and the second… All racks 24 are set on the inner wall of the elliptical ring 25.

A first threaded rod 11 is driven by the end of the second belt 17 away from the connecting rod 19.

[0021] In one embodiment, for the aforementioned outer cabinet 1, a rotating plate 3 is rotatably connected to the side of the outer cabinet 1, and a solar roof plate 2 is provided on the top of the outer cabinet 1.

[0022] In one embodiment, for the outer cabinet 1, the bottom of the outer cabinet 1 is provided with a ramp for water droplet flow, and the bottom of the outer cabinet 1 is provided with a square groove for placing the mesh 27.

[0023] In one embodiment, the inner cabinet 4 has a square opening on its side for heat dissipation.

[0025] In one embodiment, the inner cabinet 4 is provided with a wide groove inside for the first belt 14 to drive the transmission.

[0026] In one embodiment, the second bevel gear 20 is rotatably connected to the bottom of the outer cabinet 1, and the side of the first bevel gear 18 is provided with a narrow block for support.

[0027] In this embodiment, the second bevel gear 20 is rotatably connected to the bottom of the outer cabinet 1, providing a stable connection point for power transmission. This ensures that the second bevel gear 20 maintains a stable axial position during rotation, effectively preventing power loss and component wear caused by shaking.

[0028] In one embodiment, the outer cabinet 1 has multiple sets of round legs at its bottom for support.

[0029] In this embodiment, the bottom of the outer cabinet 1 is equipped with multiple sets of round legs for support, which greatly enhances the stability of the outer cabinet 1. In the complex working environment of a water conservancy pumping station, there may be uneven ground. The multiple sets of round legs can evenly distribute the weight of the outer cabinet 1, adapt to different ground conditions, and prevent the outer cabinet 1 from tilting or even falling over due to uneven force. The stable placement of the outer cabinet 1 provides a basic guarantee for the normal operation of the internal electrical automation equipment and moisture-proof structure, avoiding damage to equipment components or changes in the relative positions of the components of the moisture-proof structure due to cabinet shaking, which would affect the realization of the moisture-proof function.

[0030] In one embodiment, the bottom of the third threaded rod 15 is fixedly connected to the output end of the motor inside its inner cabinet 4.

[0031] In this embodiment, the bottom of the third threaded rod 15 is fixedly connected to the output end of the motor inside the inner cabinet 4, ensuring that the power generated by the motor can be directly and efficiently transmitted to the third threaded rod 15. After the motor starts, the rotation speed and direction of the third threaded rod 15 can be precisely controlled, thereby driving the heat dissipation strip 16 to move stably up and down along the inner wall of the outer cabinet 1. The stable movement of the heat dissipation strip 16 can effectively regulate the airflow inside the outer cabinet 1, expel hot air, and reduce water vapor condensation. On the other hand, it drives the operation of other components, such as driving the second threaded rod 13 to rotate and clean water droplets through the first belt 14, which plays a key role in maintaining a good equipment operating environment and achieving moisture-proof function.

[0032] The working principle of the moisture-proof structure of the electrical automation equipment of the water conservancy pumping station in this invention is as follows: usually, special electrical equipment and other materials are installed inside the outer cabinet 1. Then, on a normal sunny day, the outer cabinet 1 contains a large number of electronic components and other parts that generate heat. Then, the inert gas inside 5 expands due to the heat. After the inert gas expands, it pushes 6 and further stretches the length of 8, so that 7 slides upward. After 7 slides, the heat dissipation vent is exposed, which facilitates the heat dissipation of the electronic components inside the outer cabinet 1.

[0033] Then, during rainy days, heat will still be generated inside the outer cabinet 1. This heat will accumulate inside the outer cabinet 1 through the openings on its side. Since the temperature inside the outer cabinet 1 is higher than the outside air temperature, some moisture will enter through the holes and other parts of the outer cabinet 1. Because the inner wall temperature of the outer cabinet 1 is lower, the moisture will adhere to its surface and form water droplets. At this time, a humidity sensor is installed on the inner wall of the outer cabinet 1. When the humidity reaches a certain level, the motor at the bottom of 15 will rotate. The rotation of 15 will drive 16 to move up and down along the inner wall of the outer cabinet 1. As it moves, the air inside the outer cabinet 1 is blown towards the openings on its side. The cold air is then blocked at the openings on the side of the outer cabinet 1. As 15 rotates, 14 drives 13 to rotate. The rotation of 13 pushes the water droplets on the inner wall of the outer cabinet 1 to the bottom of the outer cabinet 1, thus preventing the accumulation of too much moisture on the inner wall of the outer cabinet 1 and causing the electronic components inside the outer cabinet 1 to become damp. When 13 moves to the bottom of the outer cabinet 1, there is a sponge at the bottom of 12 and a support frame at the top. In this way, when 12 moves to the bottom of the outer cabinet 1, the moisture will be squeezed to the bottom of 1.

[0034] Then, the ramp below the outer cabinet 1 delivers water droplets to section 27. The water droplets slide to 27 and move to the outside of the outer cabinet 1. As 13 rotates, it penetrates the bottom of the outer cabinet 1, causing 22 to rotate. 22's rotation first engages with 23, and 23 causes 25 to slide at the bottom of the outer cabinet 1, allowing 26 to clean the surface of 27, preventing excessive dust from clogging and affecting water droplet flow. After 22 and 23 complete engagement, they disengage, allowing 22 and 24 to engage. 24 then causes 25 to slide in the opposite direction, allowing 26 to clean the dust from the bottom surface of 27 of the outer cabinet 1 in the opposite direction. While 22 rotates, it also causes 20 to rotate via 21. 20's rotation then engages with 18, causing 19 to rotate. 19's rotation then causes 11 to rotate via 17, and 11's rotation causes 9 to slide along the inner wall of the outer cabinet 1. Figure 7 For example, the 10 set on the side of 9 will absorb the water droplets on the top of the outer cabinet 1. Then, when 10 slides to the initial position on one side of the inner wall of the outer cabinet 1, it will use the inner wall and the squeezing of 9 to squeeze out the water droplets of 10. After 9 moves to the other side and finishes, it will move in the opposite direction to clean it again. It is worth mentioning that the motor at the bottom of 15 will control 16 to rotate to the highest point of 15 and then rotate in the opposite direction to move 16 to the bottom of the outer cabinet 1.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
