Description

Technical Field

[0001] This utility model relates to the field of pressure control and temperature regulation technology, and in particular to a pressure control and temperature regulation system for a wind turbine generator cabin. Background Technology

[0002] With the widespread application of wind power technology, the reliable operation of wind turbine generators has become an increasingly important concern. The nacelle of a wind turbine generator is typically located in a complex external environment, and changes in its internal temperature and pressure can significantly impact the performance, lifespan, and overall power generation efficiency of numerous precision devices within the generator. For example, high temperatures can cause electrical equipment to overheat, leading to malfunctions or even damage; excessively low temperatures in winter can affect the normal startup and operation of equipment; and abnormal pressure within the nacelle can affect the heat dissipation efficiency of the equipment and the normal opening and closing of the nacelle doors. Therefore, air conditioning units, cooling fans, intake valves, and exhaust valves are typically installed inside the generator nacelle. These structures are controlled by a controller electrically connected to them to regulate the temperature and pressure within the generator nacelle.

[0003] However, traditional controllers are usually installed in a certain position in the generator compartment with screws. After the controller has been working for a long time, the internal control components may malfunction, requiring the controller to be disassembled, repaired, or replaced. The screw connection method requires tools and is time-consuming and labor-intensive to disassemble the controller, making the disassembly and assembly of the controller relatively inefficient. Therefore, an improvement is needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a wind turbine generator cabin pressure control and temperature regulation system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wind turbine generator nacelle pressure and temperature control system, comprising a mounting base plate and an intelligent controller. The surface of the mounting base plate is provided with a sliding groove. A T-shaped rod is fixedly connected to the back of the intelligent controller, and the T-shaped rod is slidably connected inside the sliding groove. A square groove is provided on the side of the intelligent controller, and a locking component is provided inside the square groove. The locking component includes a locking pin, which can slide inside the square groove. One end of the locking pin is fixedly connected to a spring, and the other end of the spring is fixedly connected to the inner wall of the square groove away from the locking pin. A slot is provided on the surface of the mounting base plate at a position corresponding to the locking pin, and the other end of the locking pin is inserted into the slot. A push plate is fixedly connected to the surface of the locking pin.

[0006] Preferably, there are two sets of locking components, which are symmetrically distributed on two sides of the smart controller.

[0007] Preferably, the push plate has evenly distributed anti-slip protrusions on the outer side.

[0008] Preferably, mounting holes are provided at the four corners of the mounting base plate, and screws are inserted into the mounting holes.

[0009] Preferably, the intelligent controller has ventilation openings on its top and bottom surfaces, and a filter screen is installed at each ventilation opening.

[0010] Preferably, the top and bottom surfaces of the intelligent controller are provided with annular grooves, which are connected to the ventilation openings. A slot is provided at the bottom of the annular groove, and a magnet is fixedly connected inside the slot. A rod is fixedly connected to the side of the filter plate facing the inside of the intelligent controller. The rod is inserted into the slot and magnetically connected to the magnet. A sealing gasket is fixedly connected to the surface of the filter plate, and the sealing gasket can be locked inside the annular groove.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by opening a sliding groove on the surface of the mounting base plate, a T-shaped rod is set on the back of the intelligent controller and slidably connected to the sliding groove, and fixed with locking components (such as pins, springs, etc.), the traditional method of installing the controller by screws is abandoned. The advantage of this is that when the controller malfunctions after working for a long time and needs to be disassembled for repair or replacement, no tools are needed. The controller can be easily removed from or installed on the mounting base plate by simply operating the locking components, which greatly improves the efficiency of controller disassembly and assembly and facilitates subsequent maintenance work.

[0013] 2. In this utility model, the insert rod on the filter screen is inserted into the slot at the bottom of the annular groove and magnetically connected with a magnet. Simultaneously, with the cooperation of the sealing gasket, the filter screen can be easily installed and removed using magnetic attraction, facilitating regular cleaning or replacement and ensuring the filtration effect at the ventilation opening. Furthermore, the sealing gasket can be secured within the annular groove, enhancing the sealing at the ventilation opening and preventing excessive entry of external dust, moisture, and other adverse factors into the controller, further improving the protection of the internal components and ensuring stable and reliable controller performance.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 - Figure 6As shown, this utility model provides a technical solution: a wind turbine generator nacelle pressure and temperature control system, including a mounting base plate 1 and an intelligent controller 2. A groove 3 is formed on the surface of the mounting base plate 1. A T-shaped rod 4 is fixedly connected to the back of the intelligent controller 2, and the T-shaped rod 4 is slidably connected inside the groove 3. A square groove 5 is formed on the side of the housing of the intelligent controller 2. A locking component 6 is provided inside the square groove 5. The locking component 6 includes a latch 601, which can slide inside the square groove 5. A spring 602 is fixedly connected to one end of the latch 601, and the other end of the spring 602 is connected to the inner edge of the square groove 5 away from the latch 601. The mounting base plate 1 is fixedly connected to the wall. A slot 11 is provided on the surface of the mounting base plate 1 at the position corresponding to the locking pin 601. The other end of the locking pin 601 is inserted into the slot 11. A push plate 603 is fixedly connected to the surface of the locking pin 601. There are two sets of locking components 6. The two sets of locking components 6 are symmetrically distributed on the two sides of the intelligent controller 2. The push plate 603 is provided with uniformly distributed anti-slip protrusions 13 on the side facing outward. Mounting holes 7 are provided at the four corners of the mounting base plate 1. Screws 8 are inserted into the mounting holes 7. Ventilation openings 9 are provided on the top and bottom surfaces of the intelligent controller 2. A filter screen 12 is provided at the ventilation openings 9.

[0025] In this embodiment, by creating a groove 3 on the surface of the mounting base plate 1, a T-shaped rod 4 is provided on the back of the intelligent controller 2 and slidably connected to the groove 3, and fixed in conjunction with the locking components 6 (such as the latch 601 and spring 602). This eliminates the traditional method of installing the controller using screws. The advantage of this is that when the controller malfunctions after long-term operation and needs to be disassembled for repair or replacement, no tools are needed. The controller can be easily removed from or installed on the mounting base plate 1 simply by operating the locking components 6, greatly improving the efficiency of controller disassembly and assembly and facilitating subsequent maintenance. The locking components 6 are set in two sets and symmetrically distributed on two sides of the housing of the intelligent controller 2, making the intelligent controller 2 more stable when installed on the mounting base plate 1. The push plate 603 has evenly distributed anti-slip protrusions 13 on the outer side. When the operator manually pushes the push plate 603, it can be secured to the outer side. When operating the locking component 6 (e.g., pushing the latch 601 to disengage it from the slot 11 when unlocking the controller), the friction between the hand and the push plate 603 is increased, making operation more convenient and effortless, and reducing the risk of slippage. This further improves the convenience and efficiency of controller assembly and disassembly. Mounting holes 7 are provided at the four corners of the mounting base plate 1, and screws 8 are inserted into the mounting holes 7. This facilitates the secure fixing of the mounting base plate 1 to a suitable position inside the wind turbine generator nacelle, providing a stable installation foundation for the entire pressure and temperature control system. By setting a filter screen 12 at the ventilation opening 9, airflow is ensured while the air entering the intelligent controller 2 is filtered, preventing dust particles, lint, and other impurities from entering the intelligent controller 2 and accumulating on the components inside the intelligent controller 2, thus affecting its heat dissipation.

[0026] Example 2: As Figure 5 - Figure 6 As shown, the top and bottom surfaces of the intelligent controller 2 are provided with annular grooves 10, which are connected to the ventilation openings 9. The bottom of the annular groove 10 is provided with a slot 14, and a magnet 15 is fixedly connected inside the slot 14. A rod 16 is fixedly connected to the side of the filter screen 12 facing the inside of the intelligent controller 2. The rod 16 is inserted into the slot 14 and magnetically connected to the magnet 15. A sealing gasket 17 is fixedly connected to the surface of the filter screen 12, and the sealing gasket 17 can be locked inside the annular groove 10.

[0027] In this embodiment, the insert rod 16 on the filter screen plate 12 is inserted into the slot 14 at the bottom of the annular groove 10 and magnetically connected with the magnet 15. With the cooperation of the sealing gasket 17, the filter screen plate 12 can be easily installed and removed by magnetic attraction, which facilitates regular cleaning or replacement of the filter screen plate 12 and ensures the filtration effect at the vent 9. On the other hand, the sealing gasket 17 can be locked in the annular groove 10, which enhances the sealing of the vent 9 and prevents excessive external dust, moisture and other adverse factors from entering the controller. This further improves the protection effect of the internal components of the controller and ensures the stable and reliable performance of the controller.

[0028] The working principle of this embodiment is as follows: In use, the mounting base plate 1 is first securely installed in a suitable position inside the wind turbine nacelle using the mounting holes 7 at the four corners and the screws 8. The intelligent controller 2 is slidably connected to the groove 3 on the surface of the mounting base plate 1 via the T-shaped rod 4 on its back, achieving initial positioning and installation. Then, the locking assembly 6 is used to finally fix the intelligent controller 2. Specifically, under the elastic force of the spring 602, one end of the locking pin 601 is inserted into the corresponding groove 11 on the surface of the mounting base plate 1. Due to the elastic restoring force of the spring 602, the locking pin 601 remains in the groove 11, thereby securing the intelligent controller 2. The controller 2 is stably locked onto the mounting base plate 1. Two sets of symmetrically distributed locking components 6 work together from both sides to ensure the controller's stability. When the controller 2 needs to be disassembled for maintenance or replacement, the operator manually pushes the push plate 603. The anti-slip protrusions 13 on the push plate 603 facilitate operation. The push plate 603 causes the locking pin 601 to slide into the square groove 5 against the spring force of the spring 602, disengaging the locking pin 601 from the groove 11. The controller 2 can then be easily pulled out along the slide groove 3 without the need for tools; simply operating the locking components 6 allows the controller to be easily removed from or installed on the mounting base plate 1. This significantly improves the efficiency of controller assembly and disassembly, facilitating subsequent maintenance. When the intelligent controller 2 is operating normally, its top and bottom ventilation openings 9 ensure internal airflow for heat dissipation. The filter screen 12 at the ventilation opening 9 is magnetically connected to the magnet 15 in the slot 14 via the insertion rod 16, and, together with the sealing gasket 17, is secured in the annular groove 10 for sealing. This facilitates installation and disassembly for cleaning or replacement, and effectively prevents external dust and other impurities from entering the controller, ensuring that the internal control components operate in a good environment. The intelligent controller 2 is electrically connected to the air conditioning unit inside the generator compartment. The system controls the generator set, cooling fans, intake valves, and exhaust valves, based on pre-set programs and feedback from sensors regarding temperature and pressure inside the nacelle. This effectively regulates the temperature and pressure within the generator set nacelle, ensuring a suitable environment and the normal operation of numerous precision devices. This improves power generation efficiency and extends equipment lifespan. For example, when a sensor detects excessively high nacelle temperature, the intelligent controller 2 controls the air conditioning unit and cooling fans to accelerate heat dissipation; when pressure is abnormal, it controls the opening and closing of intake and exhaust valves to regulate pressure balance.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
