Technical Field

[0001] The invention relates to the technical field of water conservancy and flood prevention facilities, in particular to a foldable water conservancy and flood prevention device. Background Art

[0002] Flood control projects require facilities to block floodwaters and reduce their impact on protected areas. Fences are often used to protect low-lying areas near urban rivers and lakes. When implementing flood control measures on opposite bank embankments and in open areas near water sources, foldable water retaining structures and sandbags are typically used to block water, preventing high water levels from impacting urban traffic.

[0003] According to Chinese patent publication number CN209568416U, a foldable flood control device for water conservancy flood control is disclosed. The flood control device adopts an integral foldable structure. When the flood control device needs to be folded, the sleeve rod is rotated and the sleeve rod is screwed into the second placement groove of the flood control baffle by the rotation of the second rotating shaft. The flood control baffle is then rotated into the first placement groove on the base via the first rotating shaft, completing the folding of the flood control device. This structure can realize the folding of the flood control device, thereby facilitating the transportation and adjustment of the flood control device.

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figures 1-4 The present invention provides a technical solution: a foldable water conservancy and flood control device, comprising a base 1 placed horizontally on the ground, a water baffle 2 being foldably hinged on one side of the base 1, a telescopic rod 3 for adjusting the folding angle being connected between the base 1 and the water baffle 2; the telescopic rod 3 is composed of a screw rod, an adjusting nut and a pipe sleeve, the pipe sleeve of the telescopic rod 3 is movably connected to the base 1, the screw rod of the telescopic rod 3 is movably connected to the water baffle 2, and the screw rod is threadedly connected to an adjusting nut abutting the end of the pipe sleeve.

[0040] In this embodiment, the base 1 and the water baffle 2 are folded and hinged, which can facilitate the transfer and transportation of the flood control device. The base 1 is then placed on the ground and moved along the screw rod by rotating the adjusting nut, thereby driving the screw rod and the pipe sleeve to be telescopically adjusted, making it convenient for the telescopic rod 3 to support and adjust the base 1 and the water baffle 2, so that the water baffle 2 can be firmly supported when blocking floods.

[0041] See also Figures 1-4 、 Figure 12 and Figure 13 , the bottom of the base 1 is provided with an anti-seepage cloth 4 for preventing ground leakage;

[0042] A groove is provided on the surface of the base 1, and a damper 101 is installed in the groove, and a cross arm 102 is connected to the damper 101; one side of the cross arm 102 is movably connected to two parallel connecting rods 103, and the lower end of the connecting rod 103 is movably connected to an anti-slip plate 104 for sliding and tightening the anti-seepage cloth 4; the bottom wall of the anti-slip plate 104 is provided with anti-slip grooves.

[0043] In this embodiment, the damper 101 can be squeezed by pressing down the cross arm 102, so that the cross arm 102 can squeeze the anti-slip plate 104 through two parallel connecting rods 103 when moving downward. Since the connecting rod 103 can drive the anti-slip plate 104 to move along the upper surface of the anti-seepage cloth 4 when squeezing the anti-slip plate 104, the anti-seepage cloth 4 laid on the ground can be slid and tightened through the anti-slip grooves on the bottom wall of the anti-slip plate 104, and the anti-seepage cloth 4 can be stably fitted with the bottom surface of the base 1 to prevent the anti-seepage cloth 4 from loosening.

[0044] See also Figure 1 and Figure 3-Figure 8 , a pressing mechanism 5 for squeezing the anti-seepage cloth 4 into close contact with the ground is provided on the base 1, the pressing mechanism 5 includes a column 501 rotatably connected to the base 1, an adjustment groove 502 is opened on the surface of the column 501, and the adjustment groove 502 is composed of an upper straight groove, a middle spiral groove and a lower straight groove. A gear 503 is movably connected to the base 1 and docked with the column 501, and one side of the gear 503 is engaged with a tooth plate 506 that slides with the base 1;

[0045] The pressing mechanism 5 for squeezing the anti-seepage cloth 4 into close contact with the ground also includes a support plate 504 that slides longitudinally on one side of the water retaining plate 2. The surface of the support plate 504 is provided with a positioning hole that docks with the column 501, and a protruding pin 505 that docks with the adjustment groove 502 is fixed in the positioning hole.

[0046] In this embodiment, the support plate 504 is slid longitudinally along one side of the water retaining plate 2 so that the positioning opening of the support plate 504 can be docked with the column 501. At the same time, when docking the positioning opening with the column 501, the protruding pin 505 in the positioning opening is plugged into the upper end straight groove of the adjustment groove 502 on the surface of the column 501.

[0047] When a counterweight such as a sandbag or brick is placed on the support plate 504, the counterweight will press the support plate 504 downward, causing the support plate 504 to move along the adjustment groove 502 on the surface of the column 501 through the protruding pin 505 in the positioning hole. At this time, the protruding pin 505 will move along the upper straight groove, the middle spiral groove, and the lower straight groove of the adjustment groove 502 in sequence. When the protruding pin 505 presses the middle spiral groove, the column 501 will rotate, so that the column 501 can drive the gear 503 at the bottom to engage with the tooth plate 506, thereby driving the tooth plate 506 to extend and push the outer side of the base 1;

[0048] It should be noted that when counterweight components such as sandbags or bricks are placed on the support plate 504, the support plate 504 will drive the cross arm 102 to compress the damper 101, so that the counterweight component can ensure that the base 1 has sufficient stability. At the same time, the support plate 504 is separated from the base 1 to protect the counterweight component from moisture. When sandbags are used to reinforce the counterweight component, it can prevent water from wetting the sandbags and causing sand and soil loss.

[0049] See also Figure 3-Figure 7 、 Figure 10 and Figure 11 A rear limit block 507 is fixed to the upper side of one end of the tooth plate 506, and a pressure frame 508 is rotatably connected to the end of the tooth plate 506 close to the rear limit block 507, and a front limit block 509 is fixed to the upper end of the pressure frame 508 close to the rear limit block 507; a card slot 201 that matches the size of the rear limit block 507 and the front limit block 509 is opened at the bottom of the water baffle 2.

[0050] In this embodiment, when the base 1 is placed on a horizontal ground, the downward movement of the support plate 504 can squeeze the column 501 and the gear 503 to rotate together, so that the gear 503 pushes the pressing frame 508 forward through the tooth plate 506 during rotation and guides the base 1 out. When the front limit block 509 on the pressing frame 508 is engaged with the card slot 201 at the bottom of the water baffle 2, the water baffle 2 and the pressing frame 508 can be kept vertically arranged at 90 degrees.

[0051] When the front limit block 509 on the pressure frame 508 is separated from the slot 201 and the rear limit block 507 on the tooth plate 506 is docked with the slot 201, the front limit block 509 and the rear limit block 507 are fitted together, which ensures that the pressure frame 508 can still press the anti-seepage cloth 4 horizontally, ensuring that the flood control device can press and abut the anti-seepage cloth 4 on the horizontal ground.

[0052] See also Figure 5-Figure 7 , the interior of both sides of the pressing frame 508 is movably connected with a pull rod 508a through a slider, and an extrusion spring 508b is connected between the inner walls of both sides of the pressing frame 508 and the slider;

[0053] A support frame 508 c is rotatably mounted inside the pressing frame 508 and docked with the pull rod 508 a . A cross bar 508 d is fixed to one end of the support frame 508 c . A latching tooth is provided on the lower surface of the pressing frame 508 away from the tooth plate 506 .

[0054] In this embodiment, when the base 1 is placed on the ground at the top of the step and the water retaining plate 2 is close to the step surface of the step, the engagement of the gear 503 and the tooth plate 506 can enable the pressure frame 508 to guide the base 1 out, and the pressure frame 508 will be tilted and deflected toward the step surface under the action of gravity. At this time, the pull rod 508a pushed by the extrusion spring 508b will drive the abutment frame 508c to rotate and expand, and the expanded abutment frame 508c will drive the cross bar 508d to press the anti-seepage cloth 4 laid on the step surface, so that the anti-seepage cloth 4 can abut and fit the inner right angle of the step, and at the same time, through the engagement of the teeth on the lower surface of the pressure frame 508 with the outer right angle of the step surface, the anti-seepage cloth 4 can be stably and flatly fitted to the step surface of the step.

[0055] See also Figure 1 、 Figure 2 and Figure 9 A hollow water blocking plate 6 for alleviating the impact of floods is provided on the side of the water blocking plate 2 away from the base 1. The back of the hollow water blocking plate 6 is longitudinally slidably connected to the water blocking plate 2. A screw 603 plugged into the top of the water blocking plate 2 is also fixed on the back of the hollow water blocking plate 6, and a lock nut threadedly connected to the screw 603 is provided on the upper side of the water blocking plate 2.

[0056] In this embodiment, by twisting the anti-loosening nut threadedly connected to the screw 603, the anti-loosening nut is threadedly transmitted with the screw 603 at the top of the water baffle 2, thereby driving the screw 603 to pull the hollow water blocking plate 6 to move upward, and at the same time, the hollow water blocking plate 6 slides longitudinally along the water baffle 2 to ensure that the hollow water blocking plate 6 can rise smoothly; when the anti-loosening nut is loosened, the hollow water blocking plate 6 will drive the screw 603 to fall.

[0057] See also Figure 1 、 Figure 2 、 Figure 4 、 Figures 9-11 A water collection port 601 is provided on the side of the hollow water blocking plate 6 away from the water baffle 2, and an inclined drain plate 602 is integrally formed inside the hollow water blocking plate 6. A through hole is provided on the surface of the hollow water blocking plate 6 away from the water baffle 2 to facilitate the introduction of water flow, and a downward opening is provided at the bottom of the hollow water blocking plate 6.

[0058] In this embodiment, the hollow water blocking plate 6 can block the flood in front of the water retaining plate 2. When the water flow hits the hollow water blocking plate 6, the water flow will collide with the front of the hollow water blocking plate 6. The water flow generated by the impact will rush into the hollow water blocking plate 6 along the water collecting port 601 and the through port respectively, and the water flow will be diverted and discharged through the inclined drain plate 602 in the hollow water blocking plate 6, so that the hollow water blocking plate 6 has a buffering effect of water flow impact, and finally the water flow will be discharged from the opening at the bottom of the hollow water blocking plate 6;

[0059] When the water level rises and submerges the water collection port 601 of the hollow water blocking plate 6, the flood will flow in from the lower opening of the hollow water blocking plate 6. When the blocked flood flows rapidly, the drain plate 602 in the hollow water blocking plate 6 can reduce the flow rate of the water flow, thereby reducing the impact force of the water flow on the water retaining plate 2 through the hollow water blocking plate 6.

[0060] See also Figure 1-Figure 3 Pulley 1 202 and pulley 2 203 are respectively installed on the top of the water baffle 2 and the front away from the base 1. A steel wire rope 204 fixed to the hollow water blocking plate 6 and the supporting plate 504 respectively is wound between the pulley 1 202 and the pulley 2 203. The supporting plate 504 pulls the hollow water blocking plate 6 to move downward through the steel wire rope 204.

[0061] In this embodiment, when the counterweight component is placed on the support plate 504, the downward-moving support plate 504 will pull the wire rope 204 to move around the pulley 1 202 and the pulley 2 203. At this time, the wire rope 204 will pull the hollow water-blocking plate 6 downward. When the anti-loosening nut on the top of the water baffle 2 is loosened, the hollow water-blocking plate 6 will slide down longitudinally along one side of the water baffle 2. The support plate 504 is pressurized and reinforced by the counterweight component, and the hollow water-blocking plate 6 and the baffle 7 can be continuously pulled to fit the ground, which can prevent the hollow water-blocking plate 6 from shaking and floating due to the impact of floods.

[0062] See also Figure 1 、 Figure 2 、 Figure 4 、 Figures 9-11 Baffles 7 are fixed on both sides of the hollow water-blocking plate 6. A slide groove 701 is opened on the surface of the baffle 7. The filter plate 9 is slidably connected inside the slide groove 701. Guide columns docking with the slide groove 701 are fixed on the four corners on both sides of the filter plate 9. The baffles 7 are fixed on both sides of the hollow water-blocking plate 6. The baffles 7 can block the two sides of the hollow water-blocking plate 6 to prevent water from flowing from both sides of the hollow water-blocking plate 6.

[0063] See also Figure 4 、 Figures 9-11The baffle 7 is provided with a locking mechanism 8 for driving the filter plate 9 to move downward. The locking mechanism 8 for driving the filter plate 9 to move downward includes a limit rod 801 that slides horizontally on one side of the slide groove 701. A lever 802 slides longitudinally on the side of the baffle 7 close to the hollow water blocking plate 6. An inclined block for squeezing and pushing the limit rod 801 to move horizontally is fixed on the top of the lever 802.

[0064] A support plate 803 is fixed to the lower end of the lever 802, and the support plate 803 is slidably connected to the reserved groove on the back of the hollow water blocking plate 6, and a return spring 804 is connected between the top of the support plate 803 and the reserved groove to push the support plate 803 downward.

[0065] In this embodiment, when the baffles 7 on both sides of the hollow water blocking plate 6 are not falling and abutting the ground, the guide posts on the upper side of the filter plate 9 will abut the upper end of the chute 701, and the guide posts on the upper side of the filter plate 9 will be blocked and limited by the limiting rod 801;

[0066] When the support plate 504 drives the hollow water-blocking plate 6 downward through the steel wire rope 204, the hollow water-blocking plate 6 will drive the baffle plate 7 to move downward, so that the support plate 803 in the reserved groove on the back of the hollow water-blocking plate 6 will abut against the front limit block 509 on the upper side of the pressure frame 508 downward, so that the front limit block 509 will push the support plate 803 to move upward, so that the support plate 803 will compress the return spring 804. At this time, the support plate 803 will drive the lever 802 upward to move. When the lever 802 passes through the inclined block on the top and squeezes the limit rod 801, the limit rod 801 will be laterally withdrawn from the slide groove 701 and away from the guide posts on both sides of the filter plate 9. At this time, the guide posts on both sides of the filter plate 9 lose their restriction, so that the filter plate 9 will slide down along the slide groove 701 to the blocking position of the lower front side of the hollow water-blocking plate 6;

[0067] It should be emphasized that the falling filter plate 9 can block and intercept heavier and sinking debris in the flood, and the hollow water-blocking plate 6 and the filter plate 9 can cooperate to block and protect the water retaining plate 2 and the anti-seepage cloth 4, ensuring that the flood control device has a safe anti-seepage effect when in use.

[0068] Working principle: place the base 1 on the ground, support and adjust the base 1 and the water retaining plate 2 through the telescopic rod 3, so that the water retaining plate 2 can be firmly supported when blocking floods, and the anti-seepage cloth 4 is in close contact with the ground by using the counterweight component and the clamping mechanism 5 to achieve anti-seepage barrier. At the same time, a hollow water-blocking plate 6 that can alleviate the impact of floods is set in front of the water retaining plate 2, which can ensure that the water conservancy and flood control device has a buffering and decompression effect when blocking floods. The contents not described in detail in this description belong to the existing technology known to professional and technical personnel in this field.
