Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction crossing frames, in particular to a warning device applied to electric power construction crossing frames. Background Art

[0002] The electric power construction span is a facility that allows the electric power conductors to pass safely and smoothly during the circuit construction. During the construction of transmission lines, they often have to cross various obstacles such as roads, railways, communication lines, and power lines. In order to prevent the wires from being damaged and not affect the safe operation of the objects being crossed, electric power construction spans must be set up at these crossings before laying out the wires, so that the erected wires can pass safely and smoothly.

[0003] If the electric power construction crossing frame is damaged, it will cause the interruption of the construction of the transmission line, thus affecting the progress of the construction of the transmission line. At present, the safety signs of the electric power construction crossing frame are widely used in various electric power construction crossing frames in my country and even in the world. The safety signs of the electric power construction crossing frame are used to warn passing vehicles and people near the crossing frame to prevent the electric power construction crossing frame from being damaged by external forces and causing the interruption of the construction of the transmission line. However, the existing safety signs of the electric power construction crossing frame only play a certain warning role during the daytime with good lighting. It is difficult to play a warning role at night or in weather with poor lighting such as severe haze. The electric power construction crossing frame is easily damaged by external forces, affecting the construction of the transmission line.

[0004] In the prior art, for example, the Chinese invention with application number 201922208326.4 specifically discloses a luminous warning sign, including a sign body, on which a solar panel, a conversion module, a buck circuit, a control system and a light-emitting module are arranged, the solar panel is connected to the input end of the conversion module, the output end of the conversion module is simultaneously connected to the input end of the buck circuit and the input end of the light-emitting module, the output end of the buck circuit is connected to one end of the control system, and the control system is connected to the thyristor group arranged in the light-emitting module. Thus, when the vision is unclear in the dark, gloomy, rainy or foggy days, the light-emitting module is controlled to emit light, and the driver of the vehicle is warned, so as to protect the power transmission line or other materials from being damaged, and also protect the safety of the driver. However, the main parts of the solar panel, conversion module, buck circuit, control system and light-emitting module in the technical solution are arranged on the upper triangle sign, which will increase the weight of the triangle sign and make it easy to fall; on the other hand, the conversion module, buck circuit, control system and other devices are exposed to the outside and are easily affected by the external environment, which reduces the stability of the operation of each device. Summary of the invention

[0005] In order to solve the technical problems existing in the above-mentioned technology, it is necessary to provide a warning device for a power construction spanning frame.

[0007] Preferably, the installation position of the integrated box is located in the direction of the diagonal extension line of the bottom projection of the power construction spanning frame.

[0008] Preferably, the photovoltaic cell array is installed on both sides of the top of the integrated box through a bracket, and the photovoltaic cell array is rotatably connected to the bracket.

[0011] Preferably, the "Construction Ahead" safety sign, the "Slow Down" safety sign, the "No Climbing, High Voltage Danger" safety sign and the "Stop, High Voltage Danger" safety sign are connected in parallel via wires.

After the microprocessor makes a judgment, it does not send a signal to the safety sign switch, the safety sign switch remains disconnected, and the safety sign does not emit light. Therefore, when the light sensor detects that the light is dark, the safety sign is controlled to emit light, thereby improving the warning effect of the safety sign of the power construction crossing frame at night or in weather with poor lighting; and according to the detected light, the safety sign on the column of the power construction crossing frame is controlled to automatically switch between the two states of light and no light, saving manpower; at the same time, the warning device uses solar energy for power supply, does not use grid electricity, and is energy-saving and environmentally friendly. At the same time, the utility model integrates the photovoltaic controller, battery, inverter, microprocessor and safety sign switch inside the integrated box to prevent the various devices from being affected by the external environment; the integrated box is installed on the ground away from the power construction crossing frame, construction lines and obstacles.

DETAILED DESCRIPTION

[0023] The technical scheme and technical effects of the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings of the present invention.

[0024] Please see Figure 1 and Figure 2 A warning device for electric power construction spanning racks, comprising a photovoltaic assembly, a battery 3, an inverter 6, a light sensor detector 7, a microprocessor 8, a safety mark switch 9 and a safety mark 10; the photovoltaic assembly comprises a photovoltaic cell array 1 and a photovoltaic controller 2; the photovoltaic controller 2, the battery 3, the inverter 6, the microprocessor 8 and the safety mark switch 9 are integrated inside an integrated box 50, the photovoltaic cell array 1 and the light sensor detector 7 are arranged on the top of the integrated box 50, and the integrated box 50 is installed on the ground away from the electric power construction spanning rack, the construction line and obstacles; the integrated box 5 0 is provided with heat dissipation holes 501 on the side wall; the photovoltaic cell array 1 is connected to the photovoltaic controller 2 through the wire 4, and the photovoltaic controller 2 is connected to the battery 3 and the inverter 6 through the wire 4 respectively; the inverter 6 is connected to the light sensor detector 7, the microprocessor 8, and the safety mark switch 9 through the wire 4 respectively; the light sensor detector 7, the microprocessor 8 and the safety mark switch 9 are connected in sequence through the signal line 5; the safety mark switch 9 is connected to the safety mark 10 through the wire 4; the safety mark 10 is provided with a light-emitting device, and the safety mark 10 is installed on the pillar of the power construction crossing frame and faces the obstacle.

[0025] The photovoltaic cell array 1 is irradiated by sunlight to generate direct current power. The direct current power is transmitted to the photovoltaic controller 2. The photovoltaic controller 2 performs circuit control and power conversion processing on the input direct current power to ensure that the energy emitted by the photovoltaic cell array 1 can be effectively converted into the required direct current power format. The photovoltaic controller 2 transmits the processed direct current power to the battery 3 and the inverter 6 through the wire 4. The battery 3 stores the power. The inverter 6 converts direct current into alternating current and provides power to the photodetector 7, the microprocessor 8, and the safety mark switch 9 through the wire 4. The photodetector 7 is used to detect external light. Under normal circumstances, the safety mark switch 9 is in the disconnected state and is a normally open switch, that is, a switch that is in the disconnected state when there is no external force. When someone turns the switch button or the switch is turned by an automatic device, the switch is converted to a closed state, and the light-emitting device of the safety mark 10 starts to emit light accordingly.

[0026] The photovoltaic controller 2, battery 3, inverter 6, microprocessor 8 and safety mark switch 9 are integrated in the integrated box 50 to prevent the components from being affected by the external environment, and the heat dissipation holes 501 can be used to ventilate and dissipate heat inside the integrated box to ensure the normal operation of the components; the photovoltaic cell array 1 and the light sensor 7 are arranged on the top of the integrated box 50, and the integrated box 50 is installed on the ground away from the electric power construction spanning frame, construction line and obstacles, so as to prevent the photovoltaic cell array from being blocked and affecting the effect of the photovoltaic cell array in generating electricity; on the other hand, it can prevent the photovoltaic cell array, the integrated box from being too close to the electric power construction spanning frame, construction line and obstacles to generate electromagnetic interference, which affects the normal operation of the photovoltaic cell array and the integrated box. Among them, obstacles refer to roads, railways, communication lines, power lines, etc. that need to be crossed.

[0027] At night or in weather with poor lighting such as severe haze, the light sensor 7 detects that the light is dark, and transmits the signal of dark light to the microprocessor 8. After the microprocessor 8 makes a judgment, it sends a closing signal to the safety sign switch 9, the safety sign switch 9 is closed, and the safety sign 10 is illuminated. During the daytime with good lighting, the light sensor detects that the light is bright, and transmits the signal of bright light to the microprocessor 8. After the microprocessor 8 makes a judgment, it does not send a signal to the safety sign switch 9, the safety sign switch 9 remains in the disconnected state, and the safety sign 10 does not emit light. Therefore, when the light sensor detects that the light is dark, the safety sign is controlled to emit light, thereby improving the warning effect of the safety sign of the electric power construction crossing frame at night or in weather with poor lighting; and according to the detected light, the safety sign on the column of the electric power construction crossing frame is controlled to automatically switch between the two states of emitting and not emitting light, saving manpower; at the same time, the warning device uses solar energy for power supply, does not use grid electricity, and is energy-saving and environmentally friendly.

[0028] For further information, see Figure 2 The photovoltaic cell array 1 is installed on both sides of the top of the integrated box 50 through the bracket 502, and the photovoltaic cell array 1 is rotatably connected to the bracket 502. Thus, the photovoltaic cell array can be rotated to align with the sunlight, thereby improving the power generation efficiency of the photovoltaic cell array.

[0029] For further information, see Figure 3 The installation position of the integrated box is located in the direction of the diagonal extension line of the bottom projection of the power construction spanning frame. Figure 2 As shown, the diagonal extension direction of the bottom projection of the power construction crossing frame corresponds to the four positions A, B, C, and D, which do not pass through the construction lines and obstacles. Therefore, the integrated box can be installed on the ground at the positions corresponding to A, B, C, and D, so that the integrated box is just away from the power construction crossing frame, construction lines, and obstacles. On the one hand, it can prevent the photovoltaic cell array from being blocked by the power construction crossing frame, construction lines, or obstacles, affecting the effect of the photovoltaic cell array in generating electricity; on the other hand, it can prevent the photovoltaic cell array, the integrated box from being too close to the power construction crossing frame, construction lines, and obstacles to generate electromagnetic interference, thereby affecting the normal operation of the photovoltaic cell array and the integrated box.

[0030] Furthermore, the safety sign 10 is installed near the top of the electric power construction span. The electric power construction span is generally built at a high height. The safety sign 10 is installed on a column near the top of the electric power construction span, so that the safety sign 10 is higher from the ground, so that passing vehicles or nearby personnel approaching the electric power construction span can see the safety sign from a long distance, thereby improving the warning effect of the safety sign.

[0031] For further information, see Figure 4 and Figure 5 , the safety sign 10 includes a "Construction ahead" safety sign 11, a "Slow down" safety sign 12, a "No climbing high voltage danger" safety sign 13, and a "Stop high voltage danger" safety sign 14. When setting up a crossing frame, it is necessary to set up safety signs to prevent the public from mistakenly entering the construction area or touching high-voltage equipment such as cables, and to prevent pedestrians or vehicles from colliding with the crossing frame. The content of the safety sign should include warning words, prohibition words, etc., generally including "Construction ahead", "Slow down", "No climbing high voltage danger" and "Stop high voltage danger". The light sensor 7 detects that the light is dark, and transmits the light darkness signal to the microprocessor 8. After the microprocessor 8 makes a judgment, it sends a closing signal to the safety sign switch 9. The safety sign switch 9 is closed, and the "Construction ahead" safety sign 11, the "Slow down" safety sign 12, the "No climbing high voltage danger" safety sign 13, and the "Stop high voltage danger" safety sign 14 are illuminated, so that it can also play a good warning role in weather with poor lighting.

[0032] Furthermore, the "Construction Ahead" safety sign 11, the "Slow Down" safety sign 12, the "No Climbing, High Voltage Danger" safety sign 13 and the "Stop, High Voltage Danger" safety sign 14 are connected in parallel through wires to prevent damage to one safety sign from affecting the normal lighting of other safety signs.

[0033] For further information, see Figure 5 The safety signs 10 include two groups, each group includes a "Construction Ahead" safety sign 11, a "Slow Down" safety sign 12, a "No Climbing, High Voltage Danger" safety sign 13 and a "Stop, High Voltage Danger" safety sign 14. The two groups of safety signs are installed on the front and rear sides of the power construction crossing frame respectively to serve as a warning to vehicles or pedestrians passing through the power construction crossing frame from the front and rear sides.

[0034] Furthermore, the safety sign also includes the distance from the top to the ground. When the electric power construction overpass crosses the highway, a safety sign of the distance from the top to the ground can also be set, so that vehicles that are about to pass through the overpass can estimate in advance whether their vehicle height can pass through the overpass, ensuring that there is enough space for the vehicle to pass through the overpass, effectively preventing accidents.

[0035] Furthermore, the wire between the safety sign switch 9 and the safety sign 10 adopts a shielded cable. When the safety sign switch 9 is connected to the safety sign 10 through a wire, the wire will be carried on the electric power construction spanning frame, which is prone to electromagnetic interference and affects the signal transmission between the safety sign switch 9 and the safety sign 10. Therefore, a shielded cable can be used to avoid the generation of electromagnetic interference and ensure the normal operation of the safety sign switch and the safety sign.

[0036] The above disclosure is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
