Description

Technical Field

[0001] The utility model relates to the technical field of housings or structural components of electric equipment, and in particular to an anti-collision positioning and early warning device for electric equipment. Background Art

[0002] With the rapid development of society and the economy, electricity demand continues to increase, and the scale and coverage of transmission line construction are also expanding. Hoisting operations are an indispensable and important part of the construction, maintenance, and repair of transmission lines. However, the hoisting environment is complex and changeable, and there are many safety risks. One of the key issues is maintaining a safe distance between the crane arm and the transmission line. In existing work scenarios, if the crane arm is too close to the transmission line, it is very easy to cause a high-voltage discharge accident, resulting in serious consequences such as equipment damage, power outages, and even casualties, causing huge losses to the safe operation of the power grid and the social economy.

[0003] Currently, during transmission line hoisting operations, maintaining safe distances mainly relies on manual visual inspection, empirical judgment, and some simple distance measurement tools. However, these methods have many limitations. Specifically:

[0004] 1. Manual visual inspection is easily affected by subjective factors and environmental conditions, and its accuracy is difficult to guarantee;

[0005] 2. Experience-based judgments lack scientific basis and cannot meet the needs of complex and changing operating scenarios;

[0006] 3. Although traditional distance measurement tools can provide distance information to a certain extent, their measurement accuracy is limited, their real-time performance is poor, and they cannot achieve dynamic monitoring and early warning of the boom in all directions and throughout the entire process.

[0007] Therefore, an advanced technology and system is also needed that can monitor the safe distance between the crane arm and the transmission line in real time, accurately and reliably, and issue early warning information in a timely manner.

[0008] Currently, there are distance observation methods based on machine vision to address the above issues. These methods involve taking photos of the scene, extracting the far ends of the power lines and suspended overhead equipment through image recognition, and then performing spatial calculations to determine the current distance. As the current distance approaches the safe distance, an early warning can be issued. While this technical solution can address the aforementioned issues and has good accuracy, and does not rely on fixed installation positions, reducing labor intensity, it is technically complex and costly. Furthermore, in real-world scenarios, power lines do not exist alone, and multiple power lines in an image are difficult to identify. A common problem is incorrectly determining the closest power line, resulting in large deviations in the calculation results.

[0009] In summary, it is also necessary to design a low-cost, accurately positioned distance warning device for transmission lines and high-altitude equipment. Utility Model Content

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical scheme and advantage of the embodiment of the utility model more clear, the technical scheme in the embodiment of the utility model will be described clearly and completely below by combining with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.

[0047] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0048] In the description of the present invention, it is necessary to understand that the relative relationships indicated by the terms "upper", "lower", "front", "rear", etc. are based on the order of contact with the material in the direction of rotation in actual application. They are for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the equipment or components referred to must have a specific position. Therefore, they cannot be understood as limitations on the present invention.

[0049] In the description of the present invention, “plurality” means two or more, unless otherwise clearly defined.

[0050] In this utility model, unless otherwise specified or limited, the terms "installed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0051] It is worth noting that the methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products, and their sources are not specifically limited unless otherwise specified.

[0052] It should also be noted that the "far end" described below refers to the end of the aerial equipment away from the ground or the operator, and can also be understood as the end facing and close to the target; in the geometric definition, it is specifically the end face closest to the target or the adjacent plane that can be used to install the device.

[0053] like Figure 1 As shown, this embodiment provides an anti-collision positioning warning device for electric power equipment, which mainly includes a box cover 1 and a box body 2.

[0054] The box cover 1 and the box body 2 can be assembled and disassembled to form a substantially rectangular parallelepiped structure after assembly.

[0055] Further, combined Figure 2 As shown, the box cover body 101 of this embodiment adopts a flat plate structure, which is made of aluminum alloy and has stepped through holes 103 processed at the four corners for installing screws. Figure 2-Figure 5 As shown, the box cover body 101 of this embodiment is further processed with a window structure 102, which is an open structure and is installed with an end cover 4. A press-type locking mechanism is provided between the end cover 4 and the box cover.

[0056] The push-type locking mechanism is provided with an elastic reset mechanism 402 and a memory alloy spring 104. The memory alloy spring 104 is an arc-shaped metal spring. When the deformation temperature condition is reached, the spring 104 is deformed. Figure 4 The deformation shown is in a straight state, indicated by the dotted line in the figure. Taking the common copper-zinc-aluminum alloy as an example, the memory alloy springs made from it can be deformed when the temperature rises from room temperature to a value between 50°C and 60°C by adjusting the composition ratio. Therefore, two memory alloy springs 104 are symmetrically mounted on either side of the window structure 102, with their protrusions facing inward. One end of each memory alloy spring 104 is hinged to the side of the window structure 102, while the other end is secured with a pin. A slide groove is machined into the side of the window structure 102, slidably connecting the pin and the slide groove.

[0057] The elastic reset mechanism 402 is an elastic telescopic rod, the lower portion of which is fixedly connected to the box body 2 as a fixed end, and the upper end is fixedly connected to the end cover 4 as a movable end. The lower surface of the end cover 4 is provided with a hook-shaped protrusion 401, which is used to overlap the memory alloy spring.

[0058] Therefore, in the initial working state, after the end cover 4 is pressed, the hook-shaped protrusion 401 hooks the memory alloy springs 104 on both sides, and the upper surface of the end cover 4 is basically flush with the upper surface of the box cover body 101, and the sealing strip installed on the side of the end cover 4 achieves the specific dust and water requirements. When the device is working and the temperature near the end cover 4 rises to the deformation temperature, the memory alloy springs 104 stretch to a straight structure, thereby completing the release; when the elastic reset mechanism 402 is deployed, the end cover 4 rises as shown in FIG. Figure 6 As shown, the cover 104 is separated from the main body 101, leaving a gap of height h to form an air convection channel for heat exchange, thereby achieving the purpose of rapid cooling. When the temperature of the device drops, the memory alloy spring 104 returns to its initial state. The staff presses the end cover 4, so that the hook-shaped protrusion 401 hooks the memory alloy springs 104 on both sides to complete the reset operation. The above design can automatically achieve temporary emergency heat dissipation. For example, if the temporary installation location of the entire device is directly exposed to sunlight or too close to a heat-generating component, it can increase convection to prevent internal electronic components from being damaged by heat accumulation. It also meets the dust and water requirements in daily use.

[0059] Combine Figure 7As shown, the material of the box body 201 of this embodiment is also made of aluminum alloy, and a plurality of mounting positions are provided inside it for fixing the electronic device carrier. The RTK positioning module and its supporting electronic devices, data circuits, and power supply circuits are installed on the carrier. Therefore, a half-height partition is provided in the box body 201, and is divided into a first mounting area 202 and a second mounting area 203. Among them, a connecting column 205 is provided in the first mounting area 202, a threaded blind hole is processed on the top surface, and the carrier of the RTK positioning module is installed by screws; an energy storage unit is installed in the second mounting area 203, preferably a lithium battery pack, which includes lithium battery cells and a battery management system circuit board; the energy storage unit is connected to the RTK positioning module for power supply. Correspondingly, a charging interface 212 is provided on the side of the box body 201, and is connected to the energy storage unit to realize charging without disassembly.

[0060] Furthermore, the box body 2 is provided with multiple types of electrical interfaces. Specifically, since the present embodiment specifically adopts the design of an external antenna 5 to reduce the shielding effect of the box body 2, a first interface 208 is processed on the front side of the box body main body 201 for installing an antenna plug; and a second interface 209 is also processed on the front side as a data interface to install a coaxial data cable plug, which is convenient for daily data reading of the power supply system of the device. A third interface 207 is processed on the rear side of the box body main body 201, which also serves as a data interface for connecting to a host computer to read positioning data or other data transmission. Among them, since the present embodiment adopts the design of an external antenna, a display screen can be installed on the box body 2 to display real-time information, and includes corresponding warning information. Furthermore, a speaker is configured on the carrier board inside the box body 2 for broadcasting warning information.

[0061] Threaded blind holes 204 are correspondingly processed at the four corners of the box body 201, so that the box cover 1 can be detachably connected to the box body 2 by screws.

[0062] Since the box body 2 needs to be installed on the convex part or distal end of the aerial work equipment, Figure 8As shown, the embodiment is processed with a sink structure 213 on the bottom surface of the box body, which is used to install the magnetic suction assembly, and keeps the working surface of the magnetic suction assembly flush with the bottom surface of the box body 2. Optionally, the magnetic suction assembly of the embodiment adopts an electromagnetic suction disc, and an electromagnetic shielding layer is arranged on the surface of the sink structure 213, thereby reducing the influence of the electromagnetic field generated during the energization of the electromagnetic suction disc on the internal electronic equipment, and because the foregoing design adopts a design aligned on four sides, the magnetic field leaked after the fixed adhesion with the mounting position is also reduced, thereby weakening the influence on the antenna signal. Further, in the design of the sink structure 213, a rectangular sink is adopted, and the four sides are processed into outwardly inclined surface structures 214 with an inclination angle ranging from 30° to 60°, and preferably 45°. The purpose of this design is that, in order to simplify the installation structure, the electromagnetic shielding layer and the surface of the sink structure 213 are connected by adhesive, and the electromagnetic suction disc is also glued to the electromagnetic shielding layer, so that during subsequent maintenance or replacement, tool space such as a spatula cutting position needs to be left, so the four sides are processed into inclined surface structures. Preferably, the electromagnetic shielding layer and the electromagnetic suction disc can be specifically matched with a zip-tie design, and the end part is placed on the inclined surface, and even without tools, the electromagnetic suction disc can be quickly removed by pulling the zip-tie to lose its adhesion.

[0063] The side of the box body 2 is also provided with a sliding groove 210. As shown in Figure 1 , Figure 6 and Figure 7 , a transverse sliding groove 210 is respectively processed on the front and rear sides of the box body main body 201.

[0064] The sliding groove 210 is used to install the anti-dropping structure 3. Optionally, the sliding groove 210 is a T-shaped sliding groove, and because the two sliding grooves respectively pass through the first, second and third interfaces, a segmented structure form is correspondingly formed, and an opening design of the sliding groove is formed at each interface. Further, a limiting hole 211 is correspondingly processed at both ends of the sliding groove 210. The limiting hole 211 is a ball socket structure, and the inside communicates with the sliding groove 210.

[0065] The anti-dropping structure form is various, and the anti-dropping structure 3 shown in Figure 9 is taken as an example for description. Specifically, the anti-dropping structure 3 of the embodiment includes a limiting head 301, an anti-dropping rope 302 and a suction disc 303. The limiting head 301 is a ball head structure, which is first slid into the opening of the sliding groove 210 during installation, and is slid to the end to be movably matched with the limiting hole 211. It should be noted that the opening diameter of the limiting hole 211 is smaller than the ball head diameter of the limiting head 301, but the inner diameter of the limiting hole 211 is larger than the ball head diameter of the limiting head 301, so that after the limiting head 301 is slid in, it will not slide out of the opening, and has a certain movement space.

[0066] The limit head 301 is connected to the suction cup 303 by an anti-falling rope 302. Specifically, the anti-falling rope 302 adopts an elastic drawstring, thereby preventing the box body 2 from falling further when it falls off accidentally, and can also have a buffering effect to prevent the suction cup 303 from falling off due to impact.

[0067] The suction cup 303 of this embodiment is specifically a knob-type suction cup, which is temporarily installed manually on a smooth surface of the aerial work equipment.

[0068] Optionally, multiple vertically extending ridge reinforcements 206 are provided at the lateral corners of the box body 201, corresponding to the threaded blind holes 204, to strengthen the surrounding structure of the threaded blind holes. Furthermore, when the box body 2 is impacted, these ridge reinforcements can absorb energy through deformation, protecting the internal components to a certain extent. Furthermore, the corners of the box cover 1 and the box body 2 can be chamfered.

[0069] Working principle;

[0070] Since common aerial work equipment uses a large number of iron structures, it is reasonable for this embodiment to use magnetic components as temporary fixing structures.

[0071] The operator preliminarily determines the installation location of the device of this embodiment based on the on-site conditions, such as the front side of the crane's hoisting box, where the stainless steel enclosure can be used as an effective installation area, and this position is also the plane closest to the transmission line during operation.

[0072] Therefore, the operator first fixes the suction cup in the anti-slip structure on a smooth surface near the fence or the surface of the toolbox he carries, then attaches the bottom of the box to the fence and starts the magnetic suction component. After confirming that the adsorption is firm, the specific position of the suction cup can be adjusted.

[0073] After the device is powered on, the RTK positioning module obtains the device's real-time and precise spatial position. The built-in or external computing unit then calculates the actual distance based on engineering information (the spatial position of the transmission line) and determines in real time whether the actual distance is less than or equal to the safety distance. When the actual distance is less than or equal to the safety distance, a warning message is displayed on the display screen and continuously broadcast by the built-in speaker until the actual distance exceeds the safety distance.

[0074] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Simple modifications or equivalent replacements of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
