Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic field safety equipment, specifically a fire source early warning device for photovoltaic fields. Background Technology

[0002] With the rapid development of the solar photovoltaic industry, the scale of photovoltaic power plants is constantly expanding. However, photovoltaic power plants typically occupy a large area, and their electrical equipment, cables, and surrounding vegetation all pose certain fire hazards. Once a fire occurs, it will not only cause huge economic losses but may also affect the stability and security of power supply, and even cause serious damage to the surrounding environment.

[0003] Traditional fire source monitoring methods have many limitations in the application of photovoltaic (PV) power plants. For example, fixed-location fire detectors can only monitor limited areas, making it difficult to cover the complex and varied terrain and equipment layout of the entire power plant, and easily leading to blind spots. Moreover, PV power plants have unique environments, potentially facing harsh conditions such as high temperatures, sandstorms, and ultraviolet radiation, which places higher demands on the stability and reliability of fire source monitoring equipment. In addition, the installation and maintenance of PV equipment usually require specific operating spaces and conditions, and some existing fire source warning devices may cause inconvenience to normal operation and maintenance work, or be difficult to adapt to the construction and operation needs of the power plant. Therefore, there is an urgent need for a fire source warning device that can be flexibly moved, provides comprehensive monitoring, and adapts to the special environment of PV power plants, in order to improve the timeliness and accuracy of fire warnings and ensure the safe and stable operation of PV power plants. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fire source early warning device for photovoltaic power plants, which solves the technical problems of the limitations of traditional fire source monitoring methods in the application of photovoltaic power plants.

[0005] The present invention adopts the following solution: a fire source early warning device for photovoltaic power stations, comprising a lifting platform, characterized in that: one end of the lifting platform is threadedly connected to a lead screw, and the other end is slidably connected to a guide rod; both the lead screw and the guide rod are connected to a base; a first motor is fixedly connected to one set of the bases, and the lead screw is driven by the first motor; a movable seat is slidably connected to the lifting platform; the movable seat is rotatably connected to a drive wheel that engages with the inner side wall of the lifting platform; a second motor is connected to the movable seat, and the drive wheel is driven by the second motor; a rotating disk is rotatably connected to the bottom of the movable seat; a third motor is fixedly connected to the movable seat, and the rotating disk is driven by the third motor; several fire source detection probes are hinged to the rotating disk; and an adjustment component is provided on the rotating disk for adjusting the angle of the fire source detection probes.

[0006] Preferably, the adjustment component includes an angle-adjusting telescopic rod hinged between the rotating disk and the fire source detection probe.

[0007] Preferably, the inner wall of the lifting platform is provided with a track groove, and a number of auxiliary plates are slidably connected to the bottom of the movable seat. Damping rods and springs are provided between the auxiliary plates and the movable seat, and guide wheels that cooperate with the track groove are rotatably connected to the auxiliary plates.

[0008] Preferably, the base has a shock-absorbing pad at the bottom, the shock-absorbing pad is made of rubber material, and the bottom of the shock-absorbing pad has anti-slip texture.

[0009] Preferably, the fire source detection probe is covered with a protective cover, which is made of a transparent, high-temperature resistant material.

[0010] Preferably, the lifting platform, lead screw, guide rod, movable seat, rotating disk and base are all made of rust-resistant materials, and the surfaces of the lifting platform and movable seat are coated with fire-retardant coatings.

[0011] Beneficial effects:

[0012] I. Comprehensive Monitoring: The lifting and lowering function of the lifting platform is achieved through the cooperation of the lead screw and guide rod, as well as the sliding of the moving seat on the lifting platform and the rotation of the rotating disk. This allows the fire source detection probe to move flexibly in three-dimensional space, greatly expanding the monitoring range, effectively reducing monitoring blind spots, and enabling more comprehensive and accurate fire source monitoring of photovoltaic power plants, thus improving the reliability of fire early warning.

[0013] 2. Adjustable angle: The adjustment components on the rotating disk, such as the angle adjustment telescopic rod, can precisely adjust the angle of the fire source detection probe, so that it can be aligned with different positions and directions according to actual needs, further optimizing the monitoring effect and ensuring that potential fire sources can be effectively detected even in complex site environments.

[0014] III. Stable Operation: The auxiliary plate at the bottom of the mobile base is connected to the inner sidewall track groove of the lifting platform via guide wheels, damping rods, and springs. This ensures the smoothness and reliability of the mobile base's movement, reduces the impact of vibration and shaking on fire source detection, and also helps extend the equipment's service life. The shock-absorbing pads at the bottom of the base are made of rubber and have anti-slip textures. They not only provide shock absorption and buffering to prevent displacement or damage to the device due to external vibrations, but also enhance the friction between the base and the ground, ensuring the stability of the entire device during operation. This allows it to work stably in the complex terrain and environmental conditions of photovoltaic power plants.

[0015] IV. Excellent protection performance: The transparent high-temperature resistant protective cover of the fire source detection probe can effectively protect the probe from the erosion and damage of harsh environmental factors such as high temperature, wind, sand, and dust, ensuring the stability and durability of its detection performance, reducing equipment failure and false alarms caused by environmental factors, and improving the practicality and reliability of the device.

[0016] V. Adaptability to Special Environments: The lifting platform, lead screw, guide rod, moving seat, rotating disk, and base are all made of rust-resistant materials, and the lifting platform and moving seat are coated with a fire-retardant coating, giving the entire device excellent rust and fire resistance. It can adapt to the special environment of photovoltaic power stations with high temperature, high humidity, and potential fire risks, ensuring the safety and stability of the device during long-term use, reducing maintenance costs and equipment replacement frequency, and improving economic efficiency.

[0023] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figure 1-4 The detailed description of the embodiments will clearly demonstrate this. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0024] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0025] Example 1: A fire source early warning device for photovoltaic power stations includes a lifting platform 1. The lifting platform 1 is characterized by: a lead screw 2 threadedly connected to one end and a guide rod 3 slidably connected to the other end; both the lead screw 2 and the guide rod 3 are connected to a base 4; a first motor 5 is fixedly connected to one set of the base 4, driving the lead screw 2; a movable seat 6 is slidably connected to the lifting platform 1; a drive wheel 7 fitted to the inner side wall of the lifting platform 1 is rotatably connected to the movable seat 6; a second motor 8 is connected to the movable seat 6, driving the drive wheel 7; a rotating disk 9 is rotatably connected to the bottom of the movable seat 6; a third motor 10 is fixedly connected to the movable seat 6, driving the rotating disk 9; a plurality of fire source detection probes 11 are hinged to the rotating disk 9; and an adjustment assembly is provided on the rotating disk 9 for adjusting the angle of the fire source detection probes 11.

[0026] As a further embodiment, the adjustment assembly includes an angle-adjusting telescopic rod 12 hinged between the rotating disk 9 and the fire source detection probe 11.

[0027] As a further embodiment, the inner side wall of the lifting platform 1 is provided with a track groove 13, and the bottom of the movable seat 6 is slidably connected with a plurality of auxiliary plates 14. A damping rod 15 and a spring 16 are provided between the plurality of auxiliary plates 14 and the movable seat 6. A guide wheel 17 that cooperates with the track groove 13 is rotatably connected to the auxiliary plate 14.

[0028] As a further embodiment, the base 4 is provided with a shock-absorbing pad at the bottom, the shock-absorbing pad is made of rubber material, and the bottom of the shock-absorbing pad is provided with anti-slip texture.

[0029] As a further embodiment, the fire source detection probe 11 is covered with a protective cover, which is made of a transparent high-temperature resistant material.

[0030] As a further embodiment, the lifting platform 1, lead screw 2, guide rod 3, moving seat 6, rotating disk 9 and base 4 are all made of rust-resistant materials, and the surfaces of the lifting platform 1 and moving seat 6 are coated with fire-retardant coatings.

[0031] In use, firstly, the lead screw 2 and guide rod 3 are respectively installed on two bases 4, ensuring that one end of the lead screw 2 is rotatably connected to one of the bases 4, and the first motor 5 is fixedly installed on the base 4. The output shaft of the motor 5 is connected to the lead screw 2 through a coupling or other means, so that the lead screw 2 can rotate under the drive of the first motor 5. The guide rod 3 is fixedly connected to the other base 4, which plays a guiding role for the lifting platform 1, ensuring that the lifting platform 1 can move up and down smoothly when the lead screw 2 rotates.

[0032] Next, a track groove 13 is machined on the inner wall of the lifting platform 1, and the movable seat 6 is placed on the lifting platform 1, so that the auxiliary plate 14 at the bottom of the movable seat 6 corresponds to the track groove 13. A guide wheel 17 is installed on the auxiliary plate 14, and the guide wheel 17 can roll in the track groove 13. At the same time, a damping rod 15 and a spring 16 are installed between the auxiliary plate 14 and the movable seat 6. Through the cooperation of the damping rod 15 and the spring 16, a certain buffer can be provided for the movement of the movable seat 6, and it can maintain a certain stability, avoiding excessive shaking or displacement deviation during the movement. A second motor 8 is installed on the movable seat 6, and the drive wheel 7 is connected to the output shaft of the second motor 8. At the same time, the drive wheel 7 is in contact with the inner wall of the lifting platform 1. The second motor 8 drives the drive wheel 7 to rotate, thereby driving the movable seat 6 to slide along the track groove 13 on the lifting platform 1.

[0033] Then, a rotating disk 9 is installed at the bottom of the movable base 6, and a third motor 10 is fixed on the movable base 6. The output shaft of the third motor 10 is connected to the rotating disk 9 through a suitable connection method, so that the rotating disk 9 can rotate around the vertical axis under the drive of the third motor 10. Multiple fire source detection probes 11 are hinged on the rotating disk 9, and an angle adjustment telescopic rod 12 is installed at the hinge point between each fire source detection probe 11 and the rotating disk 9. By controlling the extension and retraction length of the angle adjustment telescopic rod 12, the angle of the fire source detection probe 11 relative to the rotating disk 9 can be adjusted.

[0034] Finally, rubber shock-absorbing pads are attached or fixed to the bottom of the base 4, and anti-slip textures are machined into the bottom of the shock-absorbing pads to enhance the stability and shock absorption performance of the device on the placement surface. Meanwhile, rust-resistant materials are used to manufacture the lifting platform 1, lead screw 2, guide rod 3, moving seat 6, rotating disk 9, and base 4. A fire-retardant coating is evenly applied to the surfaces of the lifting platform 1 and moving seat 6 to improve the device's fire resistance and rust resistance, ensuring its long-term stable operation in the harsh environment of photovoltaic power plants.

[0035] When installing the fire source detection probe 11, ensure that its hinged connection with the rotating disk 9 is firm and reliable, and that the angle adjustment telescopic rod 12 can extend and retract flexibly to precisely adjust the probe angle. Properly arrange the signal transmission line of the fire source detection probe 11 to avoid tangling or damage during device movement, and connect it to the corresponding monitoring and control system for real-time processing and analysis of the detected signals.

[0036] During the debugging process, the operation of the first motor 5, the second motor 8, and the third motor 10 were controlled to raise and lower the lifting platform 1, move the movable seat 6, and rotate the rotating disk 9, respectively. The smoothness of the movement of each component and whether it could achieve the expected range of motion and accuracy requirements were checked. Simultaneously, the angle adjustment function of the fire source detection probe 11 was tested by adjusting the length of the telescopic rod 12 to ensure that it could cover the required monitoring area and accurately detect fire source signals.

[0037] For the protective cover of the fire source detection probe 11, a transparent, high-temperature resistant material, such as quartz glass or special high-temperature resistant plastic, should be selected. It should be manufactured according to the shape and size of the probe to ensure that the protective cover fits tightly onto the fire source detection probe 11 without affecting the probe's detection performance. When installing the protective cover, attention should be paid to the sealing between it and the probe to prevent dust, moisture, and other impurities from entering the protective cover and affecting the normal operation of the probe.

[0038] When the first motor 5 starts, its output shaft drives the lead screw 2 to rotate. Since the lead screw 2 is threadedly connected to the lifting platform 1, and the guide rod 3 guides the lifting platform 1 and restricts its rotational freedom, the lifting platform 1 will move up or down along the axis of the lead screw 2 under the rotation of the lead screw 2, thereby realizing the vertical position adjustment of the device so that the fire source detection probe 11 can monitor areas at different heights.

[0039] After the second motor 8 starts, the drive wheel 7 begins to rotate. Because the drive wheel 7 contacts the inner wall of the lifting platform 1 and generates friction, the movable seat 6 slides horizontally along the track groove 13 on the lifting platform 1 under the action of friction. By controlling the forward and reverse rotation and the speed of the second motor 8, the movable seat 6 can move forward, backward, left, and right on the lifting platform 1, enabling the fire source detection probe 11 to cover a wider horizontal monitoring area and further expanding the monitoring range of the device.

[0040] When the third motor 10 operates, its output shaft drives the rotating disk 9 to rotate around the vertical axis. The fire source detection probe 11 mounted on the rotating disk 9 also rotates along with it, thereby changing the orientation of the probe and enabling it to detect fire sources in areas of different directions. Through this rotation method, combined with the lifting of the lifting platform 1 and the movement of the movable seat 6, comprehensive fire source monitoring of the photovoltaic power station can be achieved, ensuring that there are no blind spots in monitoring.

[0041] One end of the angle-adjusting telescopic rod 12 is hinged to the rotating disk 9, and the other end is hinged to the fire source detection probe 11. When it is necessary to adjust the angle of the fire source detection probe 11, the tilt angle of the fire source detection probe 11 relative to the rotating disk 9 can be changed by controlling the extension and retraction length of the angle-adjusting telescopic rod 12 and utilizing the geometric principle of triangles. For example, when the telescopic rod extends, the probe will tilt upward at a certain angle; when the telescopic rod shortens, the probe will tilt downward. In this way, the angle of the probe can be precisely adjusted according to actual monitoring needs, so that it can be better aimed at areas where fire sources may exist, improving the accuracy and sensitivity of fire source detection.

[0042] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
