[0002] Water conservancy and hydropower projects have high safety protection requirements during construction and operation, especially during the construction phase.

[0003] Traditional safety fences are mostly made of simple materials such as bamboo fences and wire mesh, which can play a basic role in isolation and warning. For example, a construction safety fence for water conservancy and hydropower projects with application number CN202321663688.2 includes two pillars. The two pillars are connected to a fixed panel near the top of their adjacent sides. Two hinges are fixed to the bottom of the front side of the fixed panel near the left and right sides. This utility model uses the cooperation of various components such as the insertion rod, fixed seat, support plate, electric telescopic rod, wedge block, fixed spring, sliding rod, sliding plate and return spring to make the construction safety fence for water conservancy and hydropower projects easily move the two adjacent wedge blocks downward. The two adjacent wedge blocks drive the two adjacent sliding plates to slide to the sides on the adjacent sliding rod. The two sliding plates on the left and right sides gradually push the two adjacent insertion rods out of the inner cavity of the adjacent fixed seat and insert them into the soil, thereby providing a horizontal force to the fence and improving the stability of the fence installation.

[0004] In practical applications, security fences have limitations in terms of flexibility and inability to adapt to complex environments. At the same time, once the size of these fences is selected, they will occupy a lot of space during transportation and storage, increasing the difficulty and cost of logistics and storage.

[0013] Beneficial effects

[0014] This utility model provides a safety fence for water conservancy and hydropower projects. It offers the following advantages: The safety fence for water conservancy and hydropower projects uses two uprights and crossbars to form a basic frame. Fence panels are fixed to the ends of the crossbars. The fence panels extend outwards via a diamond-shaped telescopic frame, forming an extension mechanism. When an external force is applied to unfold the diamond-shaped telescopic frame, the fence panels expand outwards accordingly. A connecting plate slides inside the fixed plate, and an adjustment unit ensures stability during the sliding process. A fixing unit secures the connecting plate when necessary, thereby achieving fixed expansion of the fence panels, improving the overall protective effect and adapting to the needs of different locations. This solves the limitations of safety fences in practical applications, such as poor flexibility and inability to adapt to complex environments. Furthermore, once the size of these fences is selected, they occupy a large space during transportation and storage, increasing the difficulty and cost of logistics and storage.

[0015] The device is fixed to the side away from the crossbar by a mounting plate. The housing on the mounting plate contains a battery, giving the housing an independent power supply. The alarm light connected to the top of the housing can issue a warning when needed, thereby improving the safety and warning effect of the device at night or in poor visibility conditions.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical applications, security fences have limitations in terms of flexibility and inability to adapt to complex environments. At the same time, once the size of these fences is selected, they will occupy a lot of space during transportation and storage, increasing the difficulty and cost of logistics and storage.

[0023] In view of this, the safety protection fence of this water conservancy and hydropower project consists of a basic frame composed of two columns and crossbars. The ends of the crossbars are fixed with fence panels, which are extended outward by a diamond-shaped telescopic frame to form an extension mechanism. When an external force is applied to unfold the diamond-shaped telescopic frame, the fence panels expand outward accordingly. During this process, the connecting plate slides inside the fixed plate. The adjustment unit ensures stability during the sliding process, and the fixing unit fixes the connecting plate when necessary, thereby realizing the fixed expansion of the fence panels, improving the overall protection effect and adapting to the needs of different places. This solves the limitations of poor flexibility and inability to adapt to complex environments in practical applications of safety protection fences. At the same time, once the size of these fences is selected, they will occupy a lot of space during transportation and storage, increasing the difficulty and cost of logistics and storage.

[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0025] Example 1: By Figure 1 and 2It is known that a safety protection fence for a water conservancy and hydropower project includes two posts 1. Horizontal bars 2 are fixedly connected to the upper and lower sides of the two posts 1 that are close to each other. An extension mechanism 3 is provided on the side of the horizontal bars 2 away from the posts 1. The extension mechanism 3 includes: four fence panels 31, with the sidewalls of two fence panels 31 located on both sides fixedly connected to the horizontal bars 2 on both sides; three sets of diamond-shaped telescopic frames 32, installed between adjacent fence panels 31; and two fixed plates 33, which are fixedly connected to each other. The four fence panels 31 are located on the front of two spaced fence panels 31; a connecting plate 34 is provided corresponding to the fixing plate 33 and fixed to the front of the other two fence panels 31, and is attached to the front of the fixing plate 33; an adjustment unit 35 is installed between the fixing plate 33 and the connecting plate 34; a fixing unit 36 ​​is provided on the outer wall of the connecting plate 34; wherein, the four fence panels 31 are telescopically adjusted by the diamond-shaped telescopic frame 32, and the fixing plate 33 and the connecting plate 34 are connected to adjacent fence panels 31 by the adjustment unit 35 and fixed by the fixing unit 36;

[0026] In the specific implementation process, it is worth noting that the basic frame is formed by two columns 1 and a crossbar 2. The end of the crossbar 2 is fixed with a fence panel 31. The fence panel 31 is extended outward through the diamond telescopic frame 32 to form an extension mechanism 3. When an external force is applied to make the diamond telescopic frame 32 unfold, the fence panel 31 expands outward accordingly. During this process, the connecting plate 34 slides inside the fixed plate 33. The adjustment unit 35 ensures the stability during the sliding process. The fixing unit 36 ​​fixes the connecting plate 34 when necessary, thereby realizing the fixed expansion of the fence panel 31, improving the overall protection effect and adapting to the needs of different places.

[0027] Furthermore, the adjustment unit 35 includes: a slide groove 351, which is formed on the front of the fixed plate 33; and a slider 352, which is fixed to the back of the connecting plate 34 and slidably engaged with the inner wall of the slide groove 351; wherein, the slider 352 on the back of the connecting plate 34 slides inside the slide groove 351, thereby playing a role in assisting the connection of the two fence plates 31.

[0028] In the specific implementation process, it is worth noting that the cooperation of the slide groove 351 and the slider 352 provides a stable support effect when the fence panel 31 is moved, so that the connecting plate 34 can slide smoothly and stably along the slide groove 351 during the movement, thereby effectively preventing the fence panel 31 from shaking or deviating during the movement, and ensuring the accuracy and stability of the movement of the fence panel 31.

[0029] Furthermore, the fixing unit 36 ​​includes: a fixing hole 361, which is opened on the front side of the connecting plate 34; and a pin 362, which is inserted into the inner wall of the fixing hole 361 and passes through the connecting plate 34 and the fixing plate 33 in sequence; wherein, by inserting the pin 362 into different fixing holes 361, the fence panel 31 is fixed.

[0030] In the specific implementation process, it is worth noting that by inserting the pin 362 into the fixing hole 361, the fence panel 31 after the movement can be fixed in a specific position, ensuring that the fence structure is stable and reliable and meets the needs of different occasions.

[0031] Specifically, when using the safety fence of this water conservancy and hydropower project, a basic frame is formed by two uprights 1 and horizontal bars 2. A fence panel 31 is fixed to the end of the horizontal bar 2. The fence panel 31 expands outward through a diamond-shaped telescopic frame 32, forming an extension mechanism 3. When an external force is applied to expand the diamond-shaped telescopic frame 32, the fence panel 31 expands outward accordingly. During this process, a connecting plate 34 slides inside a fixed plate 33. An adjusting unit 35 ensures stability during the sliding process, and a fixing unit 36 ​​fixes the connecting plate 34 when necessary, thereby achieving the fixed expansion of the fence panel 31 and improving the overall protective effect. To meet the needs of different locations, the sliding groove 351 and the slider 352 work together to provide stable support when the fence panel 31 is moved, allowing the connecting plate 34 to slide smoothly and stably along the sliding groove 351 during the movement. This effectively prevents the fence panel 31 from shaking or shifting during the movement, ensuring the accuracy and stability of the movement of the fence panel 31. By inserting the pin 362 into the fixing hole 361, the fence panel 31 can be fixed in a specific position after the movement is completed, ensuring that the fence structure is stable and reliable, and meeting the usage needs of different occasions.

[0032] Example 2: From Figure 1-4 It can be seen that a mounting plate 6 is fixedly connected to the side of the column 1 away from the crossbar 2, a box 7 is fixedly connected to the surface of the mounting plate 6, a storage battery 5 is installed on the inner wall of the box 7, and an alarm light 8 is electrically connected to the top of the storage battery 5.

[0033] In the specific implementation process, it is worth noting that the mounting plate 6 is fixed on the side away from the crossbar 2, and the box 7 set on the mounting plate 6 is equipped with a storage battery 5, so that the box 7 has an independent power supply. The alarm light 8 connected to the top of the box 7 can issue a warning when needed, thereby improving the safety and warning effect of the device at night or under poor visibility conditions.

[0034] Furthermore, a base 9 is fixedly connected to the bottom of the column 1, and casters 10 are installed at the four corners of the base 9.

[0035] In the specific implementation process, it is worth noting that the device is connected to the base 9 by a fixed connection method. All four corners of the base 9 are equipped with casters 10. This design allows the entire device to be easily and conveniently adjusted when it needs to be moved, improving the flexibility and convenience of use.

[0036] Furthermore, the surface of the base 9 is provided with an insertion hole 11, and a fixing rod 12 is inserted into the inner wall of the insertion hole 11;

[0037] In the specific implementation process, it is worth noting that by setting the insertion holes 11 on the upper and lower surfaces of the base 9 and allowing the fixing rod 12 to be inserted into its inner wall, a stable connection between the base 9 and the fixing rod 12 is achieved, which enhances the stability and reliability of the device and effectively prevents the base 9 from shifting during use.

[0038] Furthermore, a reflective strip 4 is fixedly connected to the front of the fence panel 31;

[0039] In the specific implementation process, it is worth noting that reflective strips 4 are installed through a fixed connection on the front. This design enables the position of the fence panel 31 to be more clearly identified at night or in low light conditions, thereby enhancing safety and improving visibility for nighttime use.

[0040] Specifically, based on the above embodiment one, the mounting plate 6 is fixed to the side away from the crossbar 2. The housing 7 on the mounting plate 6 is equipped with a battery 5, so that the housing 7 has an independent power supply. The alarm light 8 connected to the top of the housing 7 can give a warning when needed, thereby improving the safety and warning effect of the device at night or in poor visibility conditions. It is connected to the base 9 by a fixed connection. The four corners of the base 9 are equipped with casters 10. This design makes it easy and convenient to adjust the position of the entire device when it needs to be moved, improving the flexibility and convenience of use. By setting the insertion holes 11 on the upper and lower surfaces of the base 9, and allowing the fixing rod 12 to be inserted into its inner wall, a stable connection between the base 9 and the fixing rod 12 is achieved, which enhances the stability and reliability of the device and effectively prevents the base 9 from shifting during use. The reflective strip 4 is equipped by a fixed connection on the front. This design makes the position of the fence panel 31 more clearly identifiable at night or in low light conditions, enhancing safety and improving visibility at night.
