Description

Technical Field

[0001] This utility model relates to the field of safety warning technology, and in particular to a safety warning device for power engineering. Background Technology

[0002] In the current field of electrical engineering, safety warning signs are usually placed at entrances to prevent unauthorized personnel from entering. These signs are designed to alert people to potential hazards in the work area or surrounding environment and guide them to take appropriate safety measures to prevent and avoid accidents.

[0003] A search revealed Chinese Patent Publication No. CN220827716U, which discloses a safety warning device for power engineering. The device includes a base with a multi-directional display component, a green energy component, and an adjustable movable component. This utility model replaces the arc-shaped display interface with a flat display page, resulting in better display effects and providing effective information for pedestrians and vehicles. It features a quick-use and retraction movable mechanism for easy transfer and handling, reducing labor intensity. Utilizing solar energy as a green energy source, it provides effective supplemental lighting at night, enabling all-weather display of warning information. However, during device movement, uneven ground can cause the casters to be impacted, potentially leading to the buckle detaching. This invention addresses this issue by providing a safety warning device for power engineering. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a safety warning device for power engineering, which aims to improve the problem in the prior art where the universal wheels are subjected to bumps when the device travels over uneven ground, which can cause the buckles to come loose.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a safety warning device for power engineering, comprising a warning panel and a base. Universal wheels are installed at the four corners of the base's bottom. Partitions are fixedly connected to the inner walls of the base. Squeezing members are slidably connected to the opposite sides of two partitions. Cylinders are fixedly connected to the left and right sides of the top of the base. One end of each cylinder penetrates the top of the base and is fixedly connected to a connecting member. Rotating plates are rotatably connected to the left and right sides of the connecting member. The bottom ends of the two rotating plates are rotatably connected to adjacent ends of the squeezing members. Multiple limiting rods are fixedly connected to the bottom of the inner wall of the base. Lifting blocks are slidably connected to the outer walls of the multiple limiting rods. Springs are fixedly connected to the outer walls of the multiple limiting rods. Support columns are slidably connected to the four corners of the base's bottom. The tops of the multiple support columns are fixedly connected to the bottom of the lifting blocks. A cleaning mechanism is provided on the front side of the warning panel.

[0006] The above technical solution involves using casters to move the warning panel directly, and activating a cylinder to press the connecting parts downwards. This, in turn, pushes the pressing parts to both sides through a rotating plate, causing the pressing parts to press the lifting blocks downwards, thus lifting the support column and completing the final support and fixation.

[0007] As a further description of the above technical solution:

[0008] The cleaning mechanism includes two shelves, with each shelf fixedly connected to the upper and lower sides of a warning panel on an adjacent side. Electric push rods are fixedly connected to the top left and right sides of the top shelf. One end of each electric push rod passes through the top of the shelf and is fixedly connected to a slider. A cleaning plate is fixedly connected between the two sliders. Connecting posts are slidably connected to the top left and right sides of the cleaning plate. A dust-collecting plate is fixedly connected to the bottom of each connecting post. A spring is fixedly connected to the outer wall of each connecting post. A dust-collecting pipe is connected to the left side of the dust-collecting plate, and one end of the dust-collecting pipe is connected to a filter box. A collection box is slidably connected to the front of the filter box, and a filter plate is slidably connected to the front of the filter box. A vacuum cleaner is connected to the right side of the filter box.

[0009] The above technical solution involves: activating the electric push rod to drive the cleaning plate between the sliders to scrape away dust from the surface of the warning panel; then activating the vacuum cleaner to suck up the falling dust through the suction plate, allowing the dust to enter the filter box through the suction pipe, where it is filtered by the filter plate and finally falls into the collection box for later processing. Simultaneously, when the suction plate moves to the bottom shelf surface, it is pressed to adhere to the cleaning plate surface, removing the dust adhering to the cleaning plate surface and improving cleaning efficiency.

[0010] As a further description of the above technical solution:

[0011] The cleaning mechanism also includes a handle, the rear end of which is fixedly connected to the front side of the collection box.

[0012] The above technical solution involves connecting a handle to the collection box, allowing the collection box to be easily retrieved by pulling the handle.

[0013] As a further description of the above technical solution:

[0014] A mounting plate is fixedly connected to the top of the base, and bolts are threaded around the top of the mounting plate.

[0015] The above technical solution involves fixing the mounting plate to the top of the base with bolts to ensure the stability of the warning panel.

[0016] As a further description of the above technical solution:

[0017] An adjustment bracket is fixedly connected to the top of the mounting plate, and the top of the adjustment bracket is fixedly connected to the bottom of the warning panel.

[0018] Through the above technical solution, the height of the warning panel can be freely adjusted, improving its practicality.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the adjustment frame is fixedly connected with reinforcing plates on all four sides, and the bottom of the multiple reinforcing plates is fixedly connected to the top of the mounting plate.

[0021] The above technical solution connects the adjustment frame and the mounting plate with a reinforcing plate, which ensures the stability of the adjustment frame.

[0022] As a further description of the above technical solution:

[0023] A controller is fixedly connected to the top right side of the warning panel. The controller is electrically connected to the electric push rod, the vacuum cleaner, and the cylinder.

[0024] The above technical solution allows for convenient and simple operation and control of the operating equipment throughout the entire device via a controller.

[0025] As a further description of the above technical solution:

[0026] The warning panel is fixedly connected to the top left and right sides with support rods, and the top of each of the two support rods is fixedly connected to a shield.

[0027] With the above technical solution, after the support rod connects and fixes the baffle plate, the baffle plate can play a blocking role.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the device is moved stably by the casters. When the cylinder pushes the connecting piece downward, the connecting piece is squeezed by the rotating plate. At this time, the end of the squeezing piece will be in contact with the top of the lifting block, and the squeezing will drive the lifting block to slide downward, thereby causing the support column to lift the entire device upward, completing the rapid support and fixation of the device. By separating the squeezing piece from the lifting block, the lifting block will retract upward under the action of the spring on the surface of the limit rod, so that the casters contact the ground and move.

[0030] 2. In this utility model, the cleaning plate is moved up and down on the surface of the warning panel by activating the electric push rod. The cleaning plate scrapes off the surface dust. At the same time, the vacuum cleaner is activated to create a negative pressure state inside the filter box. The dust that falls is sucked up by the vacuum plate and injected into the filter box through the vacuum pipe. The dust in the air is filtered by the filter plate. The filtered dust falls into the collection box, completing the subsequent cleaning. Attached Figure Description

By disengaging the pressing piece 6 from the lifting block 12, the lifting block 12 is released from the spring on the surface of the limit rod 10. Under the action of 1, it retracts upward, allowing the caster wheel 4 to contact the ground and move; and by activating the electric push rod 201, it drives the cleaning plate 203 to slide up and down on the surface of the warning panel 1, scraping off the surface dust with the cleaning plate 203. At the same time, the vacuum cleaner 211 is activated to create a negative pressure state inside the filter box 208, and the dust that falls is sucked up by the suction plate 205 and injected into the filter box 208 through the suction pipe 207.
