Description

Technical Field

[0001] This utility model relates to the field of generator set protection technology, specifically to a waterproof cover for generator set protection. Background Technology

[0002] During the operation of a generator set, its normal operation depends on a stable operating environment, and waterproofing, heat dissipation, moisture protection, and convenient maintenance are key elements to ensure the long-term reliable operation of the generator set. 1. Heat dissipation problem of traditional protective covers Traditional generator set protective covers mostly adopt a fixed structure, and their heat dissipation components (such as fans) are usually fixedly installed, which can only dissipate heat to specific areas. This leads to uneven temperature and humidity distribution inside the enclosure. Areas near the fan have good heat dissipation, while areas far from the fan are prone to high temperature or humidity, affecting the operating efficiency and service life of the generator set. 2. Maintenance issues of traditional protective covers Traditional protective covers often have fixed louvered grilles or require manual flipping. Manual flipping is laborious, especially for protective covers of large generator sets. The louvered grilles are large, and manual flipping is not only inefficient but also poses safety hazards and makes it difficult to quickly inspect and maintain the generator set.

[0003] 3. Compatibility issues of traditional protective covers Different models and power generator sets have different dimensions. The heat dissipation components of traditional protective covers, such as the height of the fan, cannot be adjusted, making it difficult to adapt to the diverse installation needs of generator sets and resulting in poor versatility.

[0004] 4. Temperature and humidity control and drainage issues of traditional protective covers Some protective covers lack effective temperature and humidity monitoring and linkage adjustment mechanisms. For example, they lack temperature and humidity sensors to work with the fan, making it impossible to flexibly adjust heat dissipation and dehumidification strategies according to the actual temperature and humidity inside the enclosure, which can easily lead to problems such as overheating or underheating. In addition, the drainage structure of traditional protective covers, such as the poorly designed drain outlet, can easily cause condensation or rainwater to accumulate inside the enclosure, leading to malfunctions such as corrosion of electrical components and short circuits. Therefore, there is an urgent need for a protective waterproof cover that can flexibly relocate heat dissipation components such as fans, easily flip louvered grilles, adapt to different generator sets, and have efficient drainage functions such as a reasonably designed drain outlet, in order to solve the problems of uneven heat dissipation and dehumidification, inconvenient maintenance, poor versatility, and easy water accumulation in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof cover for generator set protection to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A waterproof cover for generator set protection includes a housing, louvered grilles, and a fan. The louvered grilles are provided in two sets, which are rotatably installed on the left and right sides of the housing, respectively. A fan is movably installed on the top of the inner wall of the housing. The feature is that it also includes a fan displacement mechanism, which is located on the top of the inner wall of the housing and is used to adjust the position of the fan for heat dissipation and dehumidification. A flipping drive mechanism is provided on both sides of the top of the housing and is used to flip the louvered grille for maintenance operations.

[0007] A further improvement of this utility model is that the fan drive mechanism includes a longitudinal adjustment component, a temperature and humidity detection unit, a limiting bracket, a motor, a slider, and a threaded rod. The motor is fixedly installed on the left side of the top of the inner wall of the housing. The threaded rod is fixedly installed on the output end of the motor. The top of the slider is slidably engaged with the top of the inner wall of the housing. The slider is threadedly connected to the surface of the threaded rod, and its top is slidably engaged with the top of the inner wall of the housing. The limiting bracket is fixedly installed on the top of the right side of the inner wall of the housing and is rotatably engaged with the right end of the threaded rod.

[0008] Using the above technical solution, starting the motor allows the threaded rod fixed to the motor output end to rotate. Since the slider and the threaded rod are threadedly connected, the rotation of the threaded rod causes the slider, which is threadedly connected to it, to slide laterally under the limiting action of the inner wall of the housing. The sliding of the slider will drive the positioning sleeve fixed to it to move laterally in sync, thereby causing the fan fixed to the positioning sleeve to also move laterally, thus increasing the fan's coverage area and effectively improving the efficiency of heat dissipation and dehumidification. The support of the limiting bracket for the threaded rod ensures the stability of the threaded rod when rotating at high speed, avoiding a decrease in the lateral movement accuracy of the slider due to shaking, and indirectly ensuring the uniformity of fan heat dissipation and dehumidification.

[0009] A further improvement of this utility model's technical solution is as follows: the flipping drive mechanism includes a fixed plate, gears, an electric push rod, a first fixed bracket, a slide rod, and a second fixed bracket. The fixed plate is fixedly installed on the top of the louvered grille. Door hinge fasteners are fixedly installed on the top of the front and rear sides of the left side and the front and rear sides of the right side of the box body. The door hinges are rotatably installed inside the door hinge fasteners. Door hinges are fixedly installed inside the fixed plate. The second fixed bracket has four sets, and the four sets of second fixed brackets are fixedly installed at the four corners of the top of the box body. The slide rod is fixedly installed on the side of the second fixed bracket near the louvered grille. The first fixed bracket has two sets, and the two sets of first fixed brackets are fixedly installed on the left and right sides of the top of the box body, respectively. The electric push rod is fixedly installed on the first fixed bracket. A sliding sleeve is slidably fitted on the surface of the slide rod. The slide rod is fixedly installed at the output end of the electric push rod. The top of the sliding sleeve is fixedly installed at the bottom of the slide rod. The gear is fixedly installed at both ends of the slide rod. The slide rod meshes with the gear and cooperates with the electric push rod to achieve power transmission, thereby driving the fixed plate and the louvered grille to flip.

[0010] The above technical solution involves activating an electric push rod, which drives a component fixed to its output end to move horizontally. This, in turn, causes a sliding sleeve fixed to the bottom to slide smoothly along the surface of the push rod, simultaneously driving a fixed gear to move synchronously. Due to the meshing with the gear, the gear is driven to rotate, causing the fixed door hinge to rotate synchronously. Since the door hinge is fixedly installed inside the fixed plate and is rotatably mounted with the door hinge fixing component, power is transmitted to the fixed plate, thereby enabling the louvered grille fixed to the fixed plate to flip. Through the cooperation of the electric push rod and the gear, stable power transmission is achieved, avoiding any jamming during flipping.

[0011] A further improvement of this utility model is that the longitudinal adjustment component includes a slider, an adjusting rod, a positioning sleeve, and a positioning pin. The slider is threadedly connected to the surface of the threaded rod. The adjusting rod is fixedly installed at the bottom of the slider. The positioning sleeve is slidably installed on the surface of the adjusting rod. The top of the fan is fixedly installed at the bottom of the positioning sleeve. The positioning sleeve has a pin hole inside that engages with the positioning pin. The adjusting rod has several sets of equidistant positioning holes inside, and the positioning holes engage with the positioning pin. The positioning pin is movably installed inside the positioning sleeve. The positioning pin adjusts the height by changing its insertion position.

[0012] The above technical solution separates the positioning pin from the positioning sleeve and the adjusting rod, thus freeing the adjusting rod from the positioning pin. This allows the positioning sleeve to slide on the surface of the adjusting rod for longitudinal height adjustment. After adjusting to the required height, the positioning pin is then inserted into the pin hole of the positioning sleeve and into the positioning hole of the adjusting rod to fix the height, making it easy to adapt to the heat dissipation height of different generator sets.

[0013] A further improvement of the present invention is that the temperature and humidity detection unit includes a temperature and humidity sensor and a support frame. The support frame is fixedly installed on the surface of the positioning sleeve, and the temperature and humidity sensor is detachably installed on the front side of the support frame.

[0014] Using the above technical solution, the temperature and humidity sensor can move longitudinally synchronously with the positioning sleeve. Since the fan is fixedly installed at the bottom of the positioning sleeve, the temperature and humidity sensor and the fan can adjust their positions synchronously. Then, through the cooperation of the fan drive mechanism and the longitudinal adjustment component, the temperature and humidity sensor and the fan can move more accurately to the required area. The detachable installation method of the temperature and humidity sensor makes the daily maintenance and replacement of the temperature and humidity sensor more convenient.

[0015] A further improvement of this utility model is that: ball bearings are movably embedded at the four corners of the top of the slider, and the ball bearings slide in cooperation with the top of the inner wall of the box.

[0016] By adopting the above technical solution, four sets of balls can limit the sliding of the top of the slider, so that the slider can move laterally on the surface of the threaded rod in a stable manner, while reducing the gap between movements.

[0017] A further improvement of this utility model is that: drainage outlets are provided at the four corners of the bottom of the inner wall of the box, and a handle is fixedly installed at the bottom of the louvered grille on the side away from the box.

[0018] The above technical solution accelerates the discharge of condensate or a small amount of rainwater that has seeped into the box through the drain outlet, preventing water accumulation and the formation of a corrosive environment inside the box, thus protecting the electrical components of the generator set. The coordination between the handle and the flipping drive mechanism allows the louvered grille to be flipped manually by pulling the handle when the electric push rod fails, improving the emergency reliability of the equipment.

[0019] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a waterproof cover for generator set protection. By setting a fan shifting mechanism, the fan can be moved laterally and its height adjusted vertically, expanding the fan's coverage area. During generator set operation, it can perform targeted heat dissipation and dehumidification for different areas inside the enclosure, improving heat dissipation and dehumidification efficiency. This solves the problem of the lack of an effective temperature and humidity monitoring and linkage adjustment mechanism for the protective cover. For example, without temperature and humidity sensors to work with the fan, it is impossible to flexibly adjust the heat dissipation and dehumidification strategy according to the actual temperature and humidity inside the enclosure, which can easily lead to problems of excessive or insufficient heat dissipation.

[0020] 2. This utility model provides a waterproof cover for generator set protection. By setting a flipping drive mechanism, the louvered grille can be flexibly flipped. In environments where generator set maintenance is required, the louvered grille can be quickly opened, improving the convenience of maintenance operations. Attached Figure Description

There are four sets of fixed bracket 2 34, and the four sets of fixed bracket 2 34 are fixedly installed at the four corners of the top of the box body 1. Slide rod 33 is fixedly installed... The fixed bracket 34 is fixedly installed on the side near the louvered grille 21. There are two sets of fixed brackets 32, and the two sets of fixed brackets 32 are fixedly installed on the left and right sides of the top of the box body 1 respectively.

The gear 26 is fixedly installed at both ends of 31. 25 and gear 26 mesh with each other and cooperate with the electric push rod 3 to realize power transmission, thereby driving the fixed plate 2 and the louvered grille 21 to rotate.

[0026] The longitudinal adjustment assembly includes a slider 62, an adjusting rod 621, a positioning sleeve 63, and a positioning pin 65. The slider 62 is threadedly connected to the surface of the threaded rod 64. The adjusting rod 621 is fixedly installed at the bottom of the slider 62. The positioning sleeve 63 is slidably installed on the surface of the adjusting rod 621. The top of the fan 67 is fixedly installed at the bottom of the positioning sleeve 63.

[0029] Example 1: Protection of generator sets in industrial plants Inside the industrial plant, multiple generator sets of varying power operate continuously, providing power to various equipment. Due to the complex layout of the plant and the significant differences in temperature and humidity around the generator sets, the fan displacement mechanism plays a crucial role after the installation of this waterproof cover. Motor 6 starts, driving the threaded rod 64 to rotate, causing the slider 62 to slide laterally along the inner wall of the housing, thereby moving the fan 67 laterally. Simultaneously, based on the height of the generator set, the operator uses the longitudinal adjustment component to pull out the positioning pin 65, adjust the position of the positioning sleeve 63 on the adjusting rod 621, and after adjusting the fan 67 to the appropriate height, insert... The positioning pin 65 is fixed, and the temperature and humidity sensor 66 moves synchronously with the fan 67 to monitor the temperature and humidity of different areas in real time. When the temperature or humidity of a certain area is detected to be too high, the control system receives the data from the temperature and humidity sensor 66 and automatically controls the fan 67 to move to that area to enhance heat dissipation and dehumidification. For example, near a generator set close to large heat-generating equipment, the temperature is significantly higher than in other areas. The fan 67 moves quickly to this area and, through continuous operation, lowers the temperature of that area to a range suitable for the operation of the generator set, ensuring the stable operation of the generator set in complex industrial environments and effectively reducing the failure rate caused by temperature and humidity issues. Example 2: Maintenance and daily operation of outdoor temporary power stations In this outdoor temporary power station, designed to meet sudden power demands, this waterproof cover is installed. During daily operation, the drain outlet 5 of the waterproof cover plays a crucial role. The outdoor environment is variable, with frequent rainfall. After each rainfall, condensate and a small amount of rainwater seeping into the housing 1 can be quickly discharged through the drain outlet 5, preventing water accumulation from corroding the generator's electrical components. When maintenance of the generator is required, the tilting drive mechanism activates, activating the electric push rod 3. The electric push rod 3 pushes 31 to move, and the sliding sleeve 35 slides smoothly along the sliding rod 33, driving the gears. 26 moves synchronously, gears 26 and 25 mesh with each other, driving the door shaft 23 to rotate, thereby causing the louvered grille 21 to quickly flip open. With the assistance of handle 22, the staff can more easily open the louvered grille 21 completely, and quickly enter the housing 1 to conduct a comprehensive inspection and maintenance of the generator set. In an emergency replacement of a key component of the generator set, by quickly opening the louvered grille 21, the maintenance personnel quickly completed the component replacement, greatly shortening the maintenance time, ensuring the continuous power supply of the temporary power station, and meeting the emergency power needs of the surrounding area.

[0030] The working principle of the waterproof cover used for protecting this generator set will be explained in detail below.

[0031] like Figure 1-5 As shown, the operation of the waterproof cover for generator set protection is completed by the coordinated operation of the fan shifting mechanism and the flipping drive mechanism. Working principle of the fan shifting mechanism: Its core is powered by motor 6. After motor 6 starts, it drives the threaded rod 64 fixed at the output end to rotate. Since the slider 62 is threadedly connected to the threaded rod 64, and under the limiting action of the inner wall of the housing 1, the rotation of the threaded rod 64 is converted into the lateral sliding of the slider 62. When the slider 62 slides, it drives the fixed positioning sleeve 63 to move laterally in sync, thereby causing the fan 67 fixed to the positioning sleeve 63 to move laterally as well, effectively expanding the coverage area of ​​the fan 67. At the same time, the vertical adjustment component can be adjusted by pulling out the positioning pin 65, allowing the positioning sleeve 63 to slide along the adjusting rod 621 to adjust the height. After adjustment, the positioning pin 65 is inserted to fix it, realizing flexible adjustment of the vertical height of the fan 67 to adapt to the heat dissipation requirements of different generator sets. The temperature and humidity sensor 66 in the temperature and humidity detection unit moves synchronously with the positioning sleeve 63, which can monitor the temperature and humidity of different areas inside the housing 1 in real time, providing a basis for adjusting the position of the fan 67 and improving the accuracy of heat dissipation and dehumidification. In addition, the ball 61 on the top of the slider 62 slides and engages with the top of the inner wall of the housing 1 to ensure the stability of the slider 62 in lateral movement, reduce gaps and friction. The limit bracket 4 supports the threaded rod 64 to ensure its stable rotation.

[0032] Working principle of the flipping drive mechanism: When maintenance is required, the electric push rod 3 is activated, and its output end drives 31 to move, causing the sliding sleeve 35 to slide smoothly along the sliding rod 33. At the same time, it drives the gear 26 to move synchronously. Since the gear 26 meshes with the 25 at both ends of the door hinge 23, the movement of the gear 26 will drive the door hinge 23 to rotate. The door hinge 23 is fixed in the fixed plate 2 and rotates with the housing 1 through the door hinge fixing part 24. Finally, it drives the louvered grille 21 to flip, realizing convenient maintenance operation. The handle 22 on the louvered grille 21 can cooperate with the flipping drive mechanism to further improve the convenience of the flipping operation. The drain outlet 5 at the bottom of the housing 1 can drain the internal condensate in time to avoid equipment damage. Fixed bracket 1 32 and fixed bracket 2 34 respectively fix the electric push rod 3 and the sliding rod 33.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
