Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, specifically a safety protection device for personnel inspecting hydropower stations. Background Technology

[0002] Since the 20th century, with the continuous advancement of technologies such as turbines, generators, and power transmission, the scale and efficiency of hydropower stations have been greatly improved. Turbine designs have become more rational and efficient, better adapting to different head and flow conditions. Mixed-flow turbines are suitable for medium-to-high head hydropower stations, while axial-flow turbines are more suitable for low head and high flow conditions. At the same time, generator capacity has been continuously increasing, and the voltage level of transmission lines has been gradually improved, enabling hydropower stations to transmit electricity to cities and industrial centers over long distances. For example, the Three Gorges Dam in China is one of the world's largest hydropower stations, integrating multiple functions such as flood control, power generation, navigation, and water resource utilization. Its advanced technology and enormous scale represent the highest level of modern hydropower stations.

[0003] In the existing technology, when patrolling the water surface upstream and downstream of the dam, patrol personnel need to check water level changes and the condition of flood discharge facilities. Guardrails can ensure the safety of patrol personnel. However, the existing guardrails are inconvenient to fold and carry, which makes transportation more troublesome. Moreover, guardrails usually only play a protective role and are difficult to serve as a warning when people approach at night.

[0004] Therefore, a safety protection device for hydropower station inspection personnel was proposed. Utility Model Content

[0024] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0025] A preferred embodiment of the safety protection device for hydropower station inspection personnel provided by this utility model is, for example... Figure 1-5 As shown: A safety protection device for personnel inspecting hydropower stations includes two recovery recesses 1, a connecting plate 2 fixedly installed between the recovery recesses 1, a folding component 3 provided on the surface of the recovery recesses 1, a protective reinforcement component 4 provided on the surface of the connecting plate 2, and a protective rod 5 provided on the surface of the folding component 3.

[0026] The folding assembly 3 specifically includes: a first hollow rod 311, which is equidistantly and movably installed between the inner walls of the recycling recess 1; a sliding groove 312, which connects the top and bottom of the first hollow rod 311 respectively; a sliding rod 313, which is slidably connected between the inner walls of the sliding groove 312; and a second hollow rod 316, which is equidistantly and movably installed between the inner walls of another recycling recess 1.

[0027] The surface of the hollow rod 311 is fixedly connected to the surface of the protective rod 5. One end of the sliding rod 313 extends into the interior of the hollow rod 311. A locking block 314 is fixedly installed between the sliding rods 313. The outer wall of the locking block 314 is slidably connected to the inner wall of the hollow rod 311. A connecting rod 315 is fixedly installed on one side of the locking block 314. The surface of the connecting rod 315 is fixedly connected to the surface of the protective rod 5.

[0028] The surface of the second hollow rod 316 is fixedly connected to the surface of the protective rod 5. The top of the second hollow rod 316 is provided with a cross-shaped limiting groove 317. A sleeve 318 is slidably connected between the inner walls of the second hollow rod 316. A cross-shaped locking block 319 is engaged with the inner wall of the cross-shaped limiting groove 317. A pressure rod 3111 is fixedly installed on the top of the cross-shaped locking block 319. A bottom rod 3112 is fixedly installed on the bottom of the cross-shaped locking block 319. A spring 3113 is movably sleeved on the outer wall of the bottom rod 3112.

[0029] One end of the spring 3113 is fixedly connected to the top of the sleeve 318, and the other end of the spring 3113 is fixedly connected to the bottom of the cross block 319. The bottom of the bottom rod 3112 moves through the top of the sleeve 318 and extends to the top of the inner wall of the sleeve 318. The bottom of the bottom rod 3112 is fixedly connected to the limiting plate 3114. The top of the limiting plate 3114 contacts the top of the inner wall of the sleeve 318. A connecting rod 2 3115 is fixedly installed on one side of the sleeve 318. The surface of the connecting rod 2 3115 is fixedly connected to the surface of the protective rod 5.

[0030] A stabilizing rod 3116 is fixedly installed between the bottom of connecting rod 1 315 and the top of connecting rod 2 3115. A grooved rod 3117 is fixedly sleeved on the outer wall of the stabilizing rod 3116, and a magnet 3118 is fixedly installed on the inner wall surface of the grooved rod 3117.

[0031] In this example, the protective rod 5 can be extended by setting the folding component 3. When the operator presses the pressure rod 3111, it causes the cross block 319, the bottom rod 3112, and the limiting plate 3114 to descend. The cross block 319 disengages from the cross limiting groove 317 and causes the spring 3113 to compress. Then, it pushes the groove rod 3117 and the stabilizing rod 3116 to move the connecting rod 1 315 and the connecting rod 2 3115. The connecting rod 1 315 slides stably in the sliding groove 312 through the block 314 and the sliding rod 313. The connecting rod 2 3115 drives the sleeve 318 to move. The pressure rod 3111 slides in the cross limiting groove 317. The magnet 3118 can stably connect after folding, thereby achieving the folding effect. Example

[0032] Based on Embodiment 1, a preferred embodiment of the safety protection equipment for hydropower station inspection personnel provided by this utility model is as follows: Figure 1-5As shown: The protective reinforcement component 4 specifically includes: a recycling tank 411, which is connected to the top of the connecting rod 3115; a threaded block 412, which is fixedly installed between the inner walls of the recycling tank 411; a screw 413, which is threadedly connected between the inner walls of the threaded block 412; a battery 415, which is fixedly installed on one side of the connecting plate 2; and a placement slot 416, which is opened on the other side of the connecting plate 2.

[0033] A rotating block 414 is fixedly connected to the top of screw 413, and the bottom of screw 413 extends to the bottom of connecting rod 3115. An infrared thermal image sensor 417 is fixedly installed on the inner wall surface of placement groove 416. A controller 418 is fixedly installed on the inner wall surface of placement groove 416. An alarm 419 is fixedly installed on the inner wall surface of placement groove 416. Flashlights 4111 are fixedly installed at equal intervals between the inner walls of placement groove 416.

[0034] In this example, the protective reinforcement component 4 can provide a warning. The operator rotates the rotating block 414, which causes the screw 413 to rotate. Under the action of the threaded block 412, the screw moves and inserts into the soil for reinforcement. The infrared thermal sensor 417 detects when people are approaching and sends the information to the controller 418. The controller 418 activates the alarm 419 and the flashing light 4111 to sound an alarm and flash a light, warning people who are approaching. The battery 415 can power the electronic components to ensure normal operation, thereby achieving the function of protection reinforcement.

[0035] Working principle: First, the protective rod 5 can be extended by setting the folding component 3. When the operator presses the pressure rod 3111, it causes the cross block 319, the bottom rod 3112, and the limiting plate 3114 to descend. The cross block 319 disengages from the cross limiting groove 317 and causes the spring 3113 to compress. Then, it pushes the groove rod 3117 and the stabilizing rod 3116 to move the connecting rod 1 315 and the connecting rod 2 3115. The connecting rod 1 315 slides stably in the sliding groove 312 through the block 314 and the sliding rod 313. The connecting rod 2 3115 drives the sleeve 318 to move. The pressure rod 3111 slides in the cross limiting groove 317. After moving to the desired position, the cross block 319 is aligned with the cross limiting groove 317. The spring 3113 releases its stored energy, causing the block 319 to engage with the cross limiting groove 317. The limiting plate 3114 then engages with the sleeve 3117. The inner wall of the 18 is fitted together. When the protective rod 5 needs to be folded, the hollow rod 1 311 and the hollow rod 2 316 are rotated in the recycling recess 1 so that the hollow rod 1 311 and the hollow rod 2 316 are aligned. The magnets 3118 in the two recessed rods 3117 attract each other. Then, the protective reinforcement component 4 can be set to provide a warning. The operator rotates the rotating block 414 to drive the screw 413 to rotate. Under the action of the threaded block 412, it will move and insert into the soil to strengthen the connection. The infrared thermal image sensor 417 detects when people are approaching and sends the information to the controller 418. The controller 418 activates the alarm 419 and the flashing light 4111 to alarm and flash, warning people who are approaching and providing safety protection for patrol personnel. The battery 415 can power the electronic components to ensure normal operation, thereby achieving the functions of folding and protective reinforcement.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
