DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] A typical implementation of the present utility model is as follows Figure 1 As shown, an adjustable river guardrail comprises a railing column 1 and a guardrail board 2, both of which are made of stone. There are two railing columns 1, both of which are vertically fixed on the ground beside the river, and the two railing columns 1 are separated by a set distance. The guardrail board 2 is arranged between the two railing columns 1, and the two ends of the guardrail board 2 are respectively fixedly connected to the middle parts of the two railing columns 1, so that the guardrail board 2 is arranged parallel to the river, and the lower surface of the guardrail board 2 is separated from the ground by a set distance. The outer surface of the guardrail board 2 is provided with decorative floral decorations, and a railing upper support 3 is arranged between the two railing columns 1. The railing upper support 3 is made of stone, and the railing upper support 3 is a rectangular structure. The railing upper support 3 is located above the guardrail board 2, and its two ends are respectively fixedly connected to the two railing columns 1. A plurality of connecting columns 4 are arranged between the railing upper support 3 and the guardrail board 2, and the plurality of connecting columns 4 are arranged side by side. The railing upper support 3 and the guardrail board 2 are connected by the plurality of connecting columns 4, thereby increasing the structural strength of the entire guardrail.

[0026] A knob groove 5 is opened in the middle of the upper surface of the railing upper handrail 3, and the knob groove 5 is opened along the length direction of the railing upper handrail 3. A plurality of first through holes 6 are opened on the bottom surface of the knob groove 5. The plurality of first through holes 6 are arranged side by side, and the plurality of first through holes 6 are spaced a set distance apart. The first through holes 6 extend vertically downward and penetrate the railing upper handrail 3.

[0027] A plurality of second through holes 7 are formed on the upper surface of the guardrail 2 . The plurality of second through holes 7 are arranged corresponding to the plurality of first through holes 6 . The second through holes 7 extend vertically downward and penetrate the guardrail 2 .

[0028] A connecting rod 8 is provided in the first through hole 6 and the second through hole 7. The connecting rod 8 passes through the first through hole 6 and the second through hole 7 in sequence. The connecting rod 8 is rotatably connected to the first through hole 6 and the second through hole 7 respectively. A knob 9 is fixedly connected to the top of the connecting rod 8. The knob 9 is located in the knob groove 5. A baffle 10 is fixedly connected to the bottom of the connecting rod 8. The baffle 10 is located below the railing 2. A rotating shaft is provided in the middle of the bottom end of the baffle 10. The axis of the rotating shaft coincides with the axis of the connecting rod 8. The rotating shaft is rotatably connected to the ground. Rotating the knob 9 can drive the baffle 10 to rotate through the connecting rod 8.

[0029] like Figure 2 and Figure 3As shown, the transverse cross-section of the knob 9 is cross-shaped, and a fixing groove 11 is provided on the upper surface of the knob 9. The fixing groove 11 is cross-shaped. A fixing rod 12 is placed in the knob groove 5. The fixing rod 12 is arranged parallel to the bottom surface of the knob groove 5 and extends along the length direction of the knob groove 5. The length of the fixing rod 12 is less than the length of the knob groove 5.

[0030] The fixing groove 11 is matched with the fixing rod 12 so that the fixing rod 12 can be placed in the fixing groove 11 . The knob 9 can be fixed by the cooperation between the fixing groove 11 and the fixing rod 12 , thereby preventing the baffle 10 from rotating.

[0031] Specifically, Figure 4 As shown, a connecting rod 15 is provided at one end of the knob groove 5, and support rods are provided at both ends of the connecting rod 15. The support rods are vertically arranged to the connecting rod 15, one end of the support rod is fixedly connected to the bottom surface of the knob groove 5, and the other end is fixedly connected to the connecting rod 15, so that the connecting rod 15 is fixed above the bottom surface of the knob groove 5 and is at a set distance from the bottom surface of the knob groove 5, and the connecting rod 15 is arranged parallel to the bottom surface of the knob groove 5.

[0032] The connecting rod 15 is arranged perpendicular to the fixed rod 12, and one end of the fixed rod 12 is fixedly connected with a sleeve 16. The sleeve 16 is sleeved on the outside of the connecting rod 15 and is rotatably connected to the connecting rod 15, so that one end of the fixed rod 12 is rotatably connected to the connecting rod 15, and the other end of the fixed rod 12 is lifted, and the fixed rod 12 can rotate around the connecting rod 15.

[0033] When it is necessary to rotate the knob 9, lift the fixing rod 12 away from one end of the sleeve 16, and the fixing rod 12 rotates around the connecting rod 15, so that the fixing rod 12 leaves the fixing groove 11. At this time, the knob 9 is not limited by the fixing rod 12, and the knob 9 can be rotated to drive the baffle 10 to rotate. When the baffle 10 is adjusted, lower the fixing rod 12, and the fixing rod 12 re-enters the fixing groove 11, thereby limiting the rotation of the knob 9.

[0034] Through the cooperation of the fixing groove 11 and the fixing rod 12, the baffle 10 can be fixed at two angles, namely, the angle parallel to the river channel and the angle perpendicular to the river channel. When the multiple baffles 10 are parallel to the river channel, they are in a water-blocking state, and the multiple baffles 10 block the bottom of the guardrail 2, thereby preventing the river water from overflowing. When the multiple baffles 10 are perpendicular to the river channel, they are in a non-water-blocking state, and the multiple baffles 10 do not block the bottom of the guardrail 2, thereby opening up the vision of residents and not affecting the landscape effect along the river channel.

[0035] In order to ensure the landscape effect and water retaining effect, the baffle 10 is made of stone. There are multiple baffles 10, which are arranged side by side. The sum of the lengths of the multiple baffles 10 is equal to the length of the guardrail 2. Therefore, when the multiple baffles 10 are parallel to the river channel, the space below the guardrail 2 can be completely blocked to play a role in water retaining. Figure 5 As shown, positioning blocks 13 are provided at both ends of the baffle 10, and the thickness of the positioning blocks 13 is half of the thickness of the baffle 10. The positioning blocks 13 at both ends of the baffle 10 are relatively arranged, that is, the positioning block 13 at one end of the baffle 10 is arranged close to the water-facing side of the baffle 10, and the positioning block 13 at the other end of the baffle 10 is arranged close to the water-receiving side of the baffle 10. When multiple baffles 10 are parallel to the river channel, the positioning blocks 13 at the ends of two adjacent baffles 10 can contact each other, thereby fixing the baffle 10.

[0036] Positioning grooves 14 are provided at the corresponding positions of the two railing posts 1 and the baffle 10, and the positioning grooves 14 are adapted to the positioning blocks 13 of the baffle 10 close to one end of the railing posts 1, that is, the positioning groove 14 of one of the railing posts 1 is located on the water-facing side of the railing post 1, and the positioning groove 14 of the other railing post 1 is located on the water-receiving side of the railing post 1, so that the positioning blocks 13 on the baffle 10 close to the two railing posts 1 can be placed in the positioning grooves 14, thereby limiting the rotation angle of the baffle 10 and also improving the water-retaining strength of the baffle 10.

[0037] How it works

[0038] When water needs to be blocked during the flood season, Figure 1 As shown, turn the knob to drive the baffle to rotate through the connecting rod, so that the baffle is parallel to the river direction. At the same time, use the fixing rod to fix the knob to prevent the baffle from rotating. At this time, it is in the water blocking state. Use multiple baffles to block the bottom of the guardrail to prevent the river water from overflowing, make up for the hidden dangers caused by the insufficient height of the retaining wall, avoid flooding on the road, and even prevent flood disasters.

[0039] When water blocking is not required during the non-flood season, Figure 6 As shown, the knob is rotated in the opposite direction, and the baffle is driven to rotate in the opposite direction through the connecting rod, so that the baffle is perpendicular to the direction of the river. At the same time, the knob is fixed by the fixing rod to prevent the baffle from rotating. At this time, it is in a non-water-blocking state, thereby opening up the vision of residents and not affecting the landscape effect along the river.

[0040] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
