Description

Technical Field

[0001] This utility model relates to the field of electronic information board technology, and in particular to an electronic information board support device with a cleaning mechanism. Background Technology

[0002] Electronic information boards are commonly used in advertising and information dissemination. They visually present information to the audience, offering high visibility and playing a significant role in promoting products and disseminating information. Electronic information boards are becoming increasingly common in our lives. Most electronic information boards are installed outdoors, supported and fixed by a support device and protected by an external sealed glass frame to prevent damage from external impacts. However, the glass frames of current support devices are often contaminated by dust or rainwater, thus affecting the clarity of the information displayed on the electronic information board.

[0003] For example, a Chinese patent document discloses an electronic information board support device with a cleaning mechanism (publication number: CN218409283U). This patent uses the cooperation of a large telescopic joint, a small telescopic joint, a return spring and a push ring to drive the rotating sprocket to rotate when the motor starts. When the rotating sprocket rotates, it drives the driven sprocket to rotate through the chain, thereby causing the cleaning rod to reciprocate around the electronic information board and the brush to clean the screen of the electronic information board.

[0004] However, when electronic information boards encounter rainy weather, the screen surface is quickly covered by rainwater. At this time, the brush starts to work. Due to the characteristics of its material, the brush will inevitably mix the dust it adheres to with the rainwater during the cleaning process, forming a muddy stain. This mixed stain is spread on the screen by the brush. Compared with simple dust or rainwater, it covers a larger area and is more unevenly distributed, which seriously affects the screen's light transmittance and display clarity. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the problem that using a brush to clean electronic information boards can easily aggravate contamination and affect the normal viewing of the electronic information boards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electronic information board support device with a cleaning mechanism includes a mounting plate, and a movable cleaning mechanism is provided on the front side of the mounting plate.

[0008] The mobile cleaning mechanism includes a display screen body, the back of which is fixedly mounted to the front of the mounting plate. Symmetrically distributed support columns are fixedly connected to both sides of the mounting plate. A base plate is fixedly connected to the lower end of each of the two support columns, and a rain shelter is fixedly connected to the upper end of each of the two support columns. A mounting groove is provided at the upper end of the mounting plate. A servo motor is fixedly mounted on the inner wall of one side of the mounting groove. A lead screw is fixedly mounted on the output shaft of the servo motor through a coupling. One end of the lead screw is rotatably connected to the inner wall of the other side of the mounting groove through a bearing.

[0009] A spray rinsing mechanism is provided on the back of the mounting plate.

[0010] Preferably, the lead screw is externally threaded with a threaded block, and a guide rod is slidably sleeved on the inner wall of the threaded block. The two ends of the guide rod are respectively fixedly connected to the opposite sides of the two support columns.

[0011] Preferably, a movable block is fixedly connected to the front of the threaded block, a rubber scraper is fixedly connected to the back of the movable block, and a connecting block is fixedly connected to one side of the movable block.

[0012] Preferably, a push plate is fixedly connected to one end of the connecting block, a collecting hopper is fixedly connected to the front of the mounting plate, the inner wall of the collecting hopper is slidably sleeved with the outer side of the push plate, and an L-shaped scraper is fixedly connected to the front of the mounting plate.

[0013] Preferably, a sponge wiping block is fixedly connected to one side of the L-shaped scraper, and a bracket is fixedly connected to the front of the mounting plate, with a receiving cylinder movably inserted into the inner wall of the bracket.

[0014] Preferably, the spray rinsing mechanism includes a water storage tank, the front of which is fixedly connected to the back of the mounting plate, a booster pump is fixedly installed at the upper end of the water storage tank, and a delivery hose is fixedly connected to one end of the booster pump.

[0015] Preferably, one end of the delivery hose is fixedly connected to a diversion bend, a support block is fixedly sleeved on the outside of the diversion bend, one end of the support block is fixedly connected to the back of the threaded block, and a flushing nozzle arranged in a linear array is fixedly connected to the outside of the diversion bend.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be provided below with reference to relevant embodiments, and several embodiments of this utility model will be given. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0028] like Figures 1-5 As shown, this utility model provides a technical solution: an electronic information board support device with a cleaning mechanism, including a mounting plate 1, a movable cleaning mechanism on the front of the mounting plate 1, with the display screen body 2 as the core display component, and its back side is firmly connected to the mounting plate 1 to ensure the stability of the screen installation.

[0029] The symmetrically distributed support columns 21 on both sides provide reliable support for the bottom plate 22 at the lower end, allowing the device to stand stably on the ground. The rain shelter 23 at the upper end can effectively block rainwater, reduce the direct impact of rainwater on the screen and other components of the device, and extend the service life of the equipment.

[0030] The mounting slot 24 on the upper end of the mounting plate 1 provides mounting space for transmission components such as servo motor 25 and lead screw 26. The servo motor 25 serves as a power source, and its output shaft is connected to the lead screw 26. One end of the lead screw 26 is rotatably connected to the mounting slot 24 through a bearing, ensuring that the lead screw 26 can rotate stably and providing a power basis for the movement of subsequent components.

[0031] The threaded block 27, which is externally threaded to the lead screw 26, can move smoothly along the axial direction of the lead screw 26 with the cooperation of the guide rod 28 which is slidably sleeved on the inner wall. The two ends of the guide rod 28 are fixed to the support column 21, which guides and limits the movement of the threaded block 27, prevents it from rotating, and ensures the linearity and stability of the movement.

[0032] The movable block 29 connected to the front of the threaded block 27 moves synchronously with the threaded block 27. The rubber scraper 210 connected to its back uses the elasticity and wear resistance of rubber to effectively scrape away sewage and stains from the surface of the display body 2. During the scraping process, the rubber scraper 210 is in close contact with the screen and will not damage the screen coating. Compared with the traditional brush cleaning method, it provides stronger protection for the screen.

[0033] The connecting block 211 connected to one side of the moving block 29 drives the push plate 212 to slide and cooperate with the inner wall of the collection hopper 213. During the movement, the push plate 212 can push the sewage in the collection hopper 213 into the collection cylinder 217 on the bracket 216 to realize the centralized collection of sewage and facilitate subsequent regular cleaning.

[0034] The L-shaped scraper 214 connected to the front of the mounting plate 1 and the sponge wiping block 215 connected to one side can remove dirt, water stains and other stains adhering to the surface of the rubber scraper 210 during the movement of the rubber scraper 210, keeping the rubber scraper 210 clean and avoiding secondary contamination of the display screen body 2.

[0035] The sponge wiping block 215 can further wipe the rubber scraper 210 when it is reset or moved, thereby improving the cleanliness of the rubber scraper 210 and ensuring the cleaning effect on the display screen body 2, achieving an efficient and stable cleaning process.

[0036] The spray rinsing mechanism on the back of the mounting plate 1 includes a water tank 3 fixed to the front of the mounting plate 1, which provides a clean water source for the entire spray system.

[0037] The booster pump 31 connected to the upper end can draw and pressurize the clean water in the water storage tank 3, and deliver it to the diversion bend 33 through the delivery hose 32 connected to one end. The delivery hose 32 has a certain degree of flexibility and pressure resistance, which can adapt to the movement of the device components and ensure the smooth water delivery process.

[0038] The support block 34 connected to the outside of the diversion bend 33 is fixed to the threaded block 27, so that the diversion bend 33 can move synchronously with the threaded block 27, thereby realizing the moving spray of the flushing nozzle 35. The flushing nozzles 35 connected to the outside of the diversion bend 33 in a linear array can spray high-pressure water under the action of the booster pump 31.

[0039] These high-pressure water jets can cover the entire surface of the display screen body 2, effectively rinsing away dust, rainwater, stains, etc. on the screen. Especially when dealing with complex pollution scenarios where rainwater mixes with dust, the high-pressure spray can first perform preliminary cleaning of the screen, creating good conditions for subsequent scraping and cleaning by the rubber scraper 210, achieving a comprehensive and efficient cleaning effect. Combined with the mobile cleaning mechanism, it improves the overall cleaning quality of the display screen body 2.

[0040] It should be noted that all the electrical devices mentioned above are existing and mature technologies that are electrically connected to external programmable PLC controllers. Since they are existing and mature technologies, they will not be described in detail.

[0041] The working process of this utility model:

[0042] Step 1: Using an external PLC controller and time relay, the servo motor 25 and booster pump 31 are started periodically, such as every 2 hours, or automatically triggered in rainy weather, depending on the specific needs. When the booster pump 31 is working, it draws clean water from the water tank 3, pressurizes it through the delivery hose 32, and sends it into the diversion bend 33. Then, it sprays the display screen body 2 with high pressure through the linear array flushing nozzles 35. The servo motor 25 starts synchronously, and the output shaft drives the lead screw 26 to rotate clockwise. The lead screw 26 cooperates with the guide rod 28 to drive the threaded block 27 to move horizontally along the mounting groove 24, thereby driving the diversion bend 33 and the flushing nozzles 35 to move synchronously. During this process, the high-pressure water flow covers the entire surface of the display screen body 2, washing away dust, rainwater, and stains, especially effective in scenarios where rainwater mixes with dust.

[0043] Step two: When the threaded block 27 moves, the front moving block 29 simultaneously drives the rubber scraper 210 to move horizontally, scraping off the mixture of rinsing water and dirt on the display screen body 2. The scraped-off wastewater drips into the collection hopper 213 below. The connecting block 211 on one side of the moving block 29 drives the push plate 212 to slide along the inner wall of the collection hopper 213, pushing the wastewater into the collection cylinder 217 on the bracket 216 for centralized collection. At the same time, when the L-shaped scraper 214 on the front of the mounting plate 1 contacts the rubber scraper 210, it uses one end of the L-shaped structure to scrape off the rubber scraper 210. Stains adhering to the surface, such as mud and water stains, are allowed to fall into the collection cylinder 217, keeping the rubber scraper 210 clean and preventing secondary contamination of the display screen. After rinsing and wiping, the booster pump 31 stops working, and the servo motor 25 drives the lead screw 26 to rotate counterclockwise, causing the threaded block 27 and the moving block 29 to reset. During the reset process, the rubber scraper 210 comes into contact with the sponge wiping block 215, which further wipes the rubber scraper 210 to thoroughly remove stains and prevents stains from being brought to the surface of the display screen body 2 during the reset.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
