Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal display screens, and in particular to a liquid crystal display screen with a waterproof function. Background Art

[0002] Liquid crystal display is a display technology that uses the optical properties of liquid crystal materials to display images or text. Liquid crystal itself does not emit light, but through the illumination of the backlight, the arrangement of liquid crystal molecules changes, thereby adjusting the passage and reflection of light, and finally showing what we see. Liquid crystal display is a mature and widely used display technology with advantages such as thinness, low power consumption, and high resolution. Although there are some shortcomings in color performance and response speed of liquid crystal display, with the continuous advancement of technology, liquid crystal display still occupies an important position in many fields, especially in consumer electronic products such as televisions, mobile phones, and computers.

[0003] The document with the prior art publication number CN118314810A provides an outdoor high-definition waterproof LCD display with anti-heavy rain function. Through the automatic rain shielding mechanism, it can utilize the rain collecting box to collect falling rainwater to increase its own gravity and move downward, and cooperate with the pulling rope to pull the counterweight frame and the rain shield to displace the position of the rain shield and the rain collecting box to move and block the heat dissipation holes, which is beneficial for the device to utilize the gravity of collected rainwater to automatically block the heat dissipation holes, increase the service life of the built-in electronic components of the device, and improve the anti-heavy rain function of the device.

[0004] When the prior art is used, a certain amount of rainwater must be placed in the rain collecting box before the rain shield can be driven to seal the heat dissipation holes. Before a certain amount of rainwater is placed in the rain collecting box, the heat dissipation holes are turned on, allowing rainwater to easily enter. At the same time, after the rain shield seals the heat dissipation holes to make them waterproof, the heat inside the device will be trapped inside. Especially for high-power devices such as display screens, heat accumulation may affect the performance of the device and even cause overheating failures. In a sealed state, the heat inside the device is difficult to dissipate through air circulation, which may cause the temperature to be too high and affect the normal use of the display screen.

[0005] In summary, the prior art lacks a technology for fully dissipating heat from a liquid crystal display screen when it is sealed and waterproof. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the background technology and to propose a liquid crystal display screen with waterproof function.

[0010] Preferably, one end of the heat dissipation pipe passes through the inner wall of the waterproof cover and extends into the water receiving top seat, and the other end of the heat dissipation pipe passes through the inner wall of the waterproof cover and extends to the lower side. The outer wall of the heat dissipation pipe is rotatably connected to a ring frame, and a plurality of heat dissipation fins are fixedly connected to the lower surface of the ring frame, and the heat dissipation fins are slidingly contacted with the outer wall of the heat dissipation pipe. An annular rack A is fixedly connected to the top surface of the annular frame, and a polishing rod is rotatably connected to the lower surface of the annular frame, and the polishing rod is frictionally contacted with the outer wall of the heat dissipation pipe. A transmission wheel is fixedly connected to the top of the polishing rod, and an annular rack B is fixedly connected to the outer wall of the heat dissipation pipe, and the annular rack B is meshingly transmitted with the transmission wheel.

[0011] Preferably, the inner wall scraping mechanism includes a universal joint A, both ends of which are rotatably connected to the heat dissipation pipe, one end of the universal joint A passes through the inner wall of the heat dissipation pipe and extends to the outside and is connected and fixedly provided with a gear A, the gear A is meshed with an annular rack A for transmission, and one side of the gear A is connected and fixedly provided with a gear B.

[0012] Preferably, a spiral scraper rod is slidably provided at one end of the universal joint A located in the heat dissipation tube, and the spiral scraper rod is slidably contacted with the inner wall of the heat dissipation tube. A guide rod is rotatably connected to the outer wall of the upper end of the spiral scraper rod, and the guide rod is slidably provided with the inner wall of the heat dissipation tube. A concave-convex groove disk is fixedly connected to one end of the universal joint A located in the heat dissipation tube, and the inner wall of the concave-convex groove disk is slidably provided with one end of the guide rod.

[0013] Preferably, the outer wall of the transmission rod is connected and fixedly provided with a plurality of toothed discs in a linear structure, the toothed discs are meshed and transmitted with the gear B, and a driven wheel is connected and fixedly provided on the outer wall of the middle part of the transmission rod.

[0014] Preferably, the transmission mechanism includes a motor, the motor is fixedly connected to the inner wall of the waterproof cover, the output end of the motor is fixedly connected to a rotating shaft, the rotating shaft is fixedly connected to a feeding connection with a plurality of worms, and the worms are meshingly driven with a worm wheel.

[0015] Preferably, a threaded rod is fixedly connected to the rotating shaft, a push-pull frame is threadedly connected to the threaded rod, the other end of the push-pull frame passes through the waterproof cover and the water receiving top seat in sequence and is connected and fixed to the water retaining frame, a universal joint B is fixedly connected to the top end of the rotating shaft, a fixed frame is rotatably connected to the other end of the universal joint B, one end of the fixed frame is fixedly connected to the inner wall of the waterproof cover, one end of the universal joint B is fixedly connected to a driving wheel, and the driving wheel is meshed with the driven wheel for transmission.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When the waterproof plate is closed to waterproof the display screen during rain, rainwater will be filtered through the water filter top and collected into the heat dissipation pipe to keep the water clean. Thus, the heat dissipation port can be sealed and waterproofed, and rainwater can flow in the heat dissipation pipe to absorb the heat generated by the equipment inside the waterproof cover. Using rainwater as a heat dissipation medium can reduce the dependence on artificial refrigeration equipment (such as fans, air conditioners, etc.), save energy, and prevent the intrusion of external water sources while ensuring that the internal equipment can effectively dissipate heat and prevent equipment failure due to overheating. By arranging an inner wall scraping mechanism in the heat dissipation pipe, when the transmission mechanism drives the waterproof plate to open and close, it will drive the spiral scraping rod to rotate. At the same time, driven by the concave and convex groove plate, the spiral scraping rod will reciprocate up and down to scrape the rainwater sediment on the inner wall of the heat dissipation pipe to prevent the accumulation of sediment, ensure that the heat dissipation pipe always maintains a good heat exchange effect, thereby improving the heat dissipation efficiency of the equipment.

[0017] By arranging heat sinks on the outer wall of the heat pipe, the heat dissipation efficiency can be further improved. At the same time, the rotating and self-rotating polishing rod can grind off the dust attached to the outer wall of the heat pipe when the heat dissipation port is opened for heat dissipation, thereby preventing dust and dirt from affecting the heat dissipation performance. The automatic cleaning function reduces the frequency and difficulty of maintenance, and reduces the operation and maintenance costs in long-term use. By setting a liftable water retaining frame, rainwater on the top of the filter can be blocked, its falling speed can be slowed down, and the filtering and collection efficiency can be improved.
