Description

Technical Field

[0001] This utility model relates to the field of multimedia teaching equipment technology, specifically to multimedia teaching equipment for three-dimensional visualization simulation training of hydropower stations. Background Technology

[0002] Large industrial equipment plays an irreplaceable role in economic development and national defense. Maintenance-related issues permeate the entire equipment lifecycle and are crucial factors affecting its efficient and stable operation throughout its lifespan. With increasingly complex equipment structures and rising maintenance demands, industrial sectors worldwide place great emphasis on maintainability design and maintenance. As an inherent attribute of equipment, good maintainability design improves product availability and reduces maintenance costs. For some critical infrastructure equipment, maintainability can also enhance the safety of maintenance operations and reduce catastrophic accidents caused by improper maintenance.

[0003] Currently, traditional hydropower station training typically employs a model that combines theoretical instruction with on-site practical training. It generally begins with basic theoretical training, progresses to specialized knowledge lectures, and finally provides a systematic explanation using specific hydropower units. This model facilitates systematic learning, but the training cycle is lengthy. Theoretical learning lacks intuitive tools to connect and bridge the gap between abstract theory and concrete engineering practice. The trainees' basic technical skills significantly impact the training effectiveness, often necessitating on-site practical training to compensate for theoretical deficiencies. However, due to limitations imposed by equipment operating conditions, training effectiveness is generally limited, sometimes requiring multiple training sessions or targeted training programs. Furthermore, on-site practical training opportunities are only available during major power station overhauls, with limited time and space, making it difficult for trainees to have hands-on experience with equipment. Even when conditions permit, trainees cannot engage in unlimited learning and training based on their individual needs.

[0004] To address the aforementioned issues, this application proposes a multimedia teaching device for three-dimensional visualization simulation training of hydropower stations. Utility Model Content

[0005] This utility model aims to provide a multimedia teaching device for three-dimensional visualization simulation training of hydropower stations, mainly to solve the problem that the traditional hydropower station training cycle is long and trainees cannot learn and train without limit according to their own characteristics.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] The multimedia teaching equipment for 3D visualization simulation training of hydropower stations includes a chassis. A motherboard is fixedly installed inside the chassis. A side plate is detachably connected to one side of the chassis. Screws pass through the four corners of the side plate and are threaded into the chassis. A mounting bracket passes through the top of the chassis and is slidably connected to the chassis. A projector is rotatably connected to the mounting bracket. A top plate is fixedly connected to the top of the mounting bracket. A fixed frame is fixedly connected inside the chassis. A lifting component for moving the mounting bracket up and down is set on the top of the fixed frame. A drive component for rotating the projector is set on the top of the projector.

[0008] The working principle and beneficial effects of this utility model:

[0009] 1. Working Principle: When using this multimedia teaching equipment, the chassis is connected to a power source and simultaneously connected to an external monitor via a cable. The monitor controls the lifting mechanism, which in turn moves the projector upwards. Once the projector is completely removed from the chassis, the lifting mechanism stops operating. The motherboard contains a CPU, AI chip, storage control chip, digital encoder chip, and processor. After importing relevant data from the hydropower station equipment into the storage control chip, the digital encoder chip analyzes and processes the data. The processed data is then projected onto the projector to display a 3D simulation model of the hydropower station equipment, facilitating student learning about the equipment.

[0010] 2. Beneficial effects: When using this equipment to teach students, a 3D simulation model of the hydropower station equipment can be projected through the projector, which facilitates students' learning of the hydropower station equipment and effectively shortens the training cycle. By setting the projector on the chassis, the projector can be raised and lowered through the lifting component, so that when the equipment is not in use, the projector can be stored inside the chassis, thus providing a good protection effect for the projector.

[0011] Preferably, the lifting assembly includes a motor fixedly mounted on one side of the top of the mounting frame. The output end of the motor is fixedly connected to a drive wheel. Symmetrical threaded rods pass through the mounting frame and are threadedly connected to the mounting frame. The upper ends of the threaded rods are rotatably connected to the top plate. The lower end of one threaded rod is fixedly connected to the drive wheel, and the lower end of the other threaded rod is fixedly connected to a driven wheel. A belt is fitted on the drive wheel and the driven wheel. A connecting rod is fixedly connected to the bottom of the driven wheel, and the lower end of the connecting rod is rotatably connected to the mounting frame. The motor is electrically connected to the main board. After connecting a display screen to the external chassis, the motor can be started through the display screen. The operation of the motor can cause the drive wheel to rotate. The rotation of the drive wheel can cause the driven wheel to rotate synchronously through the belt. When the drive wheel and the driven wheel rotate synchronously, the two threaded rods can rotate synchronously. When the two threaded rods rotate, the mounting frame threadedly connected to them can move up and down, thereby realizing the lifting and lowering of the projector on the mounting frame.

[0012] Preferably, the driving component includes a rotating rod fixedly connected to the top of the projector. The upper end of the rotating rod extends to a mounting bracket and a top plate, and a knob is slidably connected thereto. The rotating rod is rotatably connected to both the mounting bracket and the top plate. Symmetrical sliders are fixedly connected to the upper end of the outer wall of the rotating rod. A groove matching the slider is provided on the inner wall of the knob. A limiting component for fixing the knob is provided at the bottom. When the device is in use, rotating the knob can drive the projector to rotate through the rotating rod, thereby adjusting the angle of the projector and making the device more practical.

[0013] Preferably, the limiting component includes a plug fixedly connected to the bottom of the knob, and the plugs are symmetrically arranged at the bottom of the knob. The top of the top plate has multiple slots that match the plugs, and the slots are evenly distributed in a circular array on the top plate. After rotating the knob to rotate the projector to a suitable angle, pressing the knob causes the plug at its bottom to be inserted into the slot, which can effectively fix the knob. This can effectively prevent the projector from rotating during the use of the device and affecting the projection effect, thereby effectively improving the stability of the device during use.

[0014] Preferably, the screw is an embedded hexagonal design, and the outermost end of the screw does not protrude above the outer wall of the side plate. After installation, the outermost end of the screw will not protrude above the outer wall of the side plate, thus preventing protrusion and wear. Furthermore, the embedded hexagonal design allows the screw to rotate better during installation, reducing the possibility of slippage.

[0015] Preferably, the lower end of each insert is fixedly connected to a magnet, and the bottom of the inner wall of the slot is fixedly connected to an iron piece that attracts the magnet. After pressing the knob to insert the insert at its bottom into the slot, the magnet at the lower end of the insert will attract the iron piece inside the slot, thereby fixing the insert in the slot. This can provide a better fixing effect for the knob.

[0016] Preferably, multiple ventilation holes are provided on one side of the chassis and on the side panel, and the ventilation holes are distributed in a linear array at equal intervals on one side of the chassis and on the side panel. When the device is operating, the electronic components on the motherboard inside the chassis will generate heat. Through the multiple ventilation holes provided on the chassis and the side panel, the electronic components on the motherboard can be effectively cooled, thereby ensuring the normal operation of the device.

[0017] Preferably, the motherboard integrates a wireless communication module, which is used to wirelessly connect with external mobile terminals or servers to achieve remote data interaction through wireless communication (such as Wi-Fi / Bluetooth / 4G / 5G), support synchronous updates of the cloud model library, avoid frequent manual data import, and improve the flexibility and timeliness of device use.

[0018] Preferably, the projector is a short-throw wide-angle projector, and the lens surface is covered with an anti-glare coating. The short-throw wide-angle design can project large and clear images in small spaces (such as a limited distance above the chassis). The anti-glare coating reduces ambient light interference, improves the visual presentation quality of the 3D simulation model, and optimizes the observation experience of students.

[0019] Preferably, a temperature sensor is fixedly installed on the inner wall of the chassis near the motherboard. The temperature sensor is electrically connected to the motherboard, and an alarm module is electrically connected to the motherboard. When the temperature sensor detects that the internal temperature of the chassis exceeds a preset threshold, the motherboard controls the alarm module to issue an alarm signal. The internal temperature of the chassis is monitored in real time by the temperature sensor. When the temperature rises abnormally (possibly due to prolonged operation of electronic components or poor heat dissipation), the alarm module is triggered in a timely manner (such as an audible and visual alarm) to remind the operator to check the heat dissipation system or stop using the equipment, so as to avoid damage to the motherboard and other electronic components caused by high temperature and ensure the safe operation of the equipment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4The multimedia teaching equipment for 3D visualization simulation training of hydropower stations includes a chassis 1. A motherboard 2 is fixedly installed inside the chassis 1. The motherboard 2 integrates a wireless communication module, which is used to wirelessly connect to an external mobile terminal or server to achieve remote transmission of hydropower station equipment data and real-time updates of the 3D simulation model. The motherboard 2 is fixed inside the chassis 1 with multiple screws. Multiple wiring holes are provided on one side of the chassis 1 for connecting the chassis 1 to an external power supply and display screen. The motherboard 2 contains electronic components such as a CPU, AI chip, storage control chip, digital encoder chip, and processor. A side panel 3 is detachably connected to one side of the chassis 1. Multiple ventilation holes 23 are provided on one side of the chassis 1 and on the side panel 3. Ventilation holes 23 are linearly arrayed and equidistantly distributed on one side of the chassis 1 and on the side panel 3. The ventilation holes 23 can effectively dissipate heat from the electronic components on the motherboard 2, thereby ensuring the normal operation of the device. Screws 4 are inserted through the four corners of the side panel 3. The screws 4 are threaded to the chassis 1. The side panel 3 is fixed by multiple screws 4, which not only makes the side panel 3 more stable after installation, but also makes the side panel 3 easier to disassemble, thus facilitating the maintenance of the inside of the chassis 1 by the staff. The screws 4 are embedded hexagonal. The embedded hexagonal screws 4 can rotate better during installation and reduce the possibility of slippage. The outermost end of the screw 4 does not exceed the outer side wall of the side panel 3, so that the screw 4 will not protrude and cause wear after installation.

[0027] A mounting bracket 5 runs through the top of chassis 1 and is slidably connected to chassis 1. A projector 6 is rotatably connected to the mounting bracket 5. The projector 6 is a short-throw wide-angle projector with an anti-glare coating on its lens surface. The short-throw wide-angle design allows for the projection of large, clear images in small spaces (such as the limited distance above chassis 1). The anti-glare coating reduces ambient light interference, improves the visual presentation quality of the 3D simulation model, and optimizes the student's observation experience. The projector 6 is electrically connected to the motherboard 2. A top plate 7 is fixedly connected to the top of the mounting bracket 5. A fixing bracket 8 is fixedly connected inside chassis 1. The top of the fixing bracket 8 is equipped with a lifting component for moving the mounting bracket 5 up and down. This multimedia teaching... When using the equipment, connect the power supply to the chassis 1 and connect the chassis 1 to an external monitor via a cable. The monitor can control the operation of the lifting component, which will cause the mounting bracket 5 to move the projector 6 upward. After the projector 6 is completely removed from the chassis 1, a three-dimensional simulation model of the hydropower station equipment can be projected through the projector 6, which facilitates students' learning of the hydropower station equipment. When the equipment is not in use, the projector 6 can be stored inside the chassis 1, which provides a better protection for the projector 6. The top of the projector 6 is equipped with a drive component for rotating it. The angle of the projector 6 can be adjusted through the drive component, which makes the equipment more practical.

[0028] A temperature sensor 24 is fixedly installed on the inner wall of the chassis 1 near the motherboard 2. The temperature sensor 24 is electrically connected to the motherboard 2, and an alarm module 25 is electrically connected to the motherboard 2. When the temperature sensor 24 detects that the internal temperature of the chassis 1 exceeds a preset threshold, the motherboard 2 controls the alarm module 25 to issue an alarm signal. The temperature sensor 24 monitors the internal temperature of the chassis 1 in real time. When the temperature rises abnormally (possibly due to prolonged operation of electronic components or poor heat dissipation), the alarm module 25 is triggered in a timely manner (such as an audible and visual alarm) to remind the operator to check the heat dissipation system or suspend the use of the equipment, so as to avoid damage to the motherboard 2 and other electronic components caused by high temperature and ensure the safe operation of the equipment.

[0029] like Figure 2 and Figure 3 As shown, the lifting assembly includes a motor 9 fixedly mounted on one side of the top of a fixed frame 8. A drive wheel 10 is fixedly connected to the output end of the motor 9. Symmetrical threaded rods 11 pass through the mounting frame 5 and are threadedly connected to the mounting frame 5. The upper ends of the threaded rods 11 are rotatably connected to the top plate 7. The lower end of one threaded rod 11 is fixedly connected to the drive wheel 10, and the lower end of the other threaded rod 11 is fixedly connected to a driven wheel 12. A belt 14 is fitted onto the drive wheel 10 and the driven wheel 12. A belt 14 is fixedly connected to the bottom of the driven wheel 12. Link 13, the lower end of which is rotatably connected to the fixed frame 8, and motor 9 is electrically connected to the main board 2. After the external display screen is connected to the chassis 1, the motor 9 can be started through the display screen. The operation of motor 9 can make drive wheel 10 rotate. The rotation of drive wheel 10 can make driven wheel 12 rotate synchronously through belt 14. When drive wheel 10 and driven wheel 12 rotate synchronously, they can make two threaded rods 11 rotate synchronously. When the two threaded rods 11 rotate, they can make the mounting frame 5 connected to them move up and down, thereby realizing the lifting and lowering of projector 6 on mounting frame 5.

[0030] like Figure 2 and Figure 4As shown, the driving assembly includes a rotating rod 15 fixedly connected to the top of the projector 6. The upper end of the rotating rod 15 extends out to the mounting bracket 5 and the top plate 7 and is slidably connected to a knob 16. The rotating rod 15 is rotatably connected to both the mounting bracket 5 and the top plate 7. Symmetrical sliders 17 are fixedly connected to the upper end of the outer wall of the rotating rod 15. The inner wall of the knob 16 has a groove 18 that matches the slider 17. A limiting assembly for fixing the knob 16 is provided at the bottom. The limiting assembly includes a plug 19 fixedly connected to the bottom of the knob 16, and the plugs 19 are symmetrically arranged at the bottom of the knob 16. The top of the top plate 7 has multiple slots 20 that match the plugs 19, and the slots 20 are evenly distributed in a circular array. On the top plate 7, magnets 21 are fixedly connected to the lower ends of the inserts 19, and iron pieces 22 attracted to the magnets 21 are fixedly connected to the bottom of the inner wall of the slot 20. When the device is in use, rotating the knob 16 can drive the projector 6 to rotate through the rotating rod 15, thereby adjusting the angle of the projector 6. After the projector 6 is rotated to a suitable angle, press the knob 16 so that the inserts 19 at the bottom are inserted into the slot 20. The magnets 21 at the lower ends of the inserts 19 will attract the iron pieces 22 inside the slot 20, which can effectively fix the knob 16. This can effectively prevent the projector 6 from rotating during the use of the device and affecting the projection effect, thereby effectively improving the stability of the device during use.

[0031] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0032] When using this multimedia teaching equipment, the power supply to the chassis 1 is turned on, and the chassis 1 is connected to an external monitor via a cable. The monitor can control the motor 9 to start. The operation of the motor 9 causes the drive wheel 10 to rotate. The rotation of the drive wheel 10 causes the driven wheel 12 to rotate synchronously via the belt 14. When the drive wheel 10 and the driven wheel 12 rotate synchronously, the two threaded rods 11 rotate synchronously. When the two threaded rods 11 rotate, the mounting bracket 5 connected to them by threads moves upward. When the projector 6 is completely removed from the chassis 1, the motor 9 stops operating. Then, turning the knob 16 will cause the projector 6 to rotate via the rotating rod 15, thereby adjusting the angle of the projector 6. After the projector 6 is rotated to the appropriate angle, press the knob 16 so that the insert 19 at the bottom is inserted into the slot 20. The magnet 2 at the lower end of the insert 19... The knob 16 is attracted to the iron plate 22 inside the slot 20, which can effectively fix the knob 16. This can effectively prevent the projector 6 from rotating during the use of the device and affecting the projection effect. The motherboard 2 is equipped with a CPU, AI chip, storage control chip, digital encoder chip and processor. After the relevant data of the hydropower station equipment is imported into the storage control chip, the data is analyzed and processed by the digital encoder chip. After the data is analyzed and processed by the digital encoder chip, the projector 6 can project a three-dimensional simulation model of the hydropower station equipment, which can facilitate students to learn about the hydropower station equipment. After the device is used, the control motor 9 reverses so that the mounting bracket 5 can move the projector 6 downward, so that the projector 6 can be stored inside the chassis 1, which can provide a good protection for the projector 6.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
