DETAILED DESCRIPTION

[0031] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0032] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the technical solutions of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In the description of the embodiments of the present invention, unless otherwise specified, “plurality” means two or more.

[0034] like Figures 1 to 8 As shown, the present invention provides a water retaining device for water conservancy project construction, including a water retaining plate 1, a power supply device and a plurality of fixed components, the power supply device is arranged on the side wall of the water retaining plate 1, the bottom end of the water retaining plate 1 is provided with a plurality of grooves 2, and a plurality of fixed components are arranged in the plurality of grooves 2 in a one-to-one correspondence, the fixed component includes a telescopic cylinder 3 and an insertion rod 4, the fixed end of the telescopic cylinder 3 is fixed to the bottom of the groove 2, the telescopic end is connected to the insertion rod 4, the telescopic cylinder 3 is telescopic to drive the insertion rod 4 to extend or retract into the groove 2, and each telescopic cylinder 3 is connected to the power supply device.

[0035] It can be understood that when water is blocked, the water baffle 1 is lifted by a crane and placed in the water, and then the position of the water baffle 1 is adjusted. When the position of the water baffle 1 is determined, the power supply device supplies power to the telescopic cylinder 3, and the telescopic end of the telescopic cylinder 3 extends out to squeeze the plug rod 4, so that the plug rod 4 moves to the outside of the groove 2 and is inserted into the river bottom, thereby fixing the position of the water baffle 1. Compared with the prior art, the plug rod 4 of the present invention is initially in the groove 2, and the movement of the water baffle 1 is not restricted. After the water baffle 1 is placed, the plug rod 4 is extended and fixed, so as to avoid the plug rod 4 affecting the placement of the water baffle 1.

[0036] In the embodiment provided by the present invention, a sliding sealing ring 5 is provided at one end of the insertion rod 4 connected to the telescopic cylinder 3 .

[0037] It can be understood that since the telescopic cylinder 3 and the insertion rod 4 in the groove 2 are in the water for a long time, although the telescopic cylinder 3 can be waterproofed, the water composition in the river is complex and may be corrosive to a certain extent. It is necessary to avoid direct contact with water as much as possible. Therefore, a sliding sealing ring 5 is provided on the insertion rod 4 to seal the groove 2 without affecting the movement of the insertion rod 4, so as to prevent river water from entering the position where the telescopic cylinder 3 is located, thereby affecting the telescopic cylinder 3.

[0038] Furthermore, an anti-drop block 7 is provided at the mouth of the groove 2, and an anti-drop protrusion 6 is provided at one end of the insertion rod 4 connected to the telescopic cylinder 3, and the anti-drop block 7 restricts the anti-drop protrusion 6 to prevent the telescopic cylinder 3 from pushing the insertion rod 4 out of the groove 2;

[0039] Secondly, the sliding sealing ring 5 is arranged between the anti-drop protrusion 6 and the anti-drop block 7. When the telescopic cylinder 3 squeezes the insertion rod 4, the anti-drop protrusion 6 squeezes the sliding sealing ring 5 on the anti-drop block 7, further preventing river water from entering the groove 2.

[0040] Optionally, the anti-drop block 7 is detachably connected to the water baffle plate 1 at the groove 2, so that the groove 2 can be cleaned after use to remove debris on the side wall of the groove 2 to avoid affecting the sealing effect.

[0041] In the embodiment provided by the present invention, a fastener 9 is provided at the notch of the groove 2 , and a plurality of teeth 8 are provided on the side wall of the insertion rod 4 along the length direction, and the fastener 9 cooperates with the teeth 8 .

[0042] It can be understood that when the telescopic cylinder 3 pushes the insertion rod 4 out of the groove 2, the insertion rod 4 is inserted into the river bottom. If the telescopic cylinder 3 is always in a working state, the life of the telescopic cylinder 3 is affected. After the telescopic cylinder 3 extends the insertion rod 4 out of the groove 2 to fix the water retaining plate 1, the insertion rod 4 can be limited to prevent the insertion rod 4 from retracting into the groove 2. In this way, there is no need for the telescopic cylinder 3 to work all the time to squeeze the insertion rod 4. Therefore, the fastener 9 and the teeth 8 can cooperate to prevent the insertion rod 4 from retracting into the groove 2.

[0043] Optionally, the fastener 9 may be arranged in a circle around the insertion rod 4 in the circumferential direction, and the teeth 8 may also be arranged in a circle on the side wall of the insertion rod 4 in the circumferential direction to match the fastener 9 arranged in a circle.

[0044] In the embodiment provided by the present invention, the water retaining plate 1 is provided with a sliding groove 12 along the height direction, and the power supply device is slidably connected to the sliding groove 12. The power supply device includes a hydroelectric generator 10 and a floating block 11, the floating block 11 is slidably connected to the sliding groove 12, the hydroelectric generator 10 is connected to the floating block 11, and the floating block 11 drives the hydroelectric generator 10 to move along the height direction of the water retaining plate 1.

[0045] It can be understood that the power supply device adopts a hydroelectric generator 10, which uses the flow of water in the river to generate electricity. It does not need an external power supply, achieves self-sufficiency, and can also avoid additional wiring.

[0046] It can be understood that the hydroelectric generator 10 is set on the floating block 11, so that the hydroelectric generator 10 can automatically adjust its position according to the water level in the river, so that the hydroelectric generator 10 can always generate electricity, avoiding the water level in the river rising or falling and causing the hydroelectric generator 10 to be unable to generate electricity.

[0047] Optionally, the excess electric energy of the hydroelectric generator 10 can be stored for use during construction.

[0048] In the embodiment provided by the present invention, the body of the hydroelectric generator 10 is located inside the floating block 11, and the propeller of the hydroelectric generator 10 is located outside the floating block 11, so that the water flow drives the propeller of the hydroelectric generator 10 to rotate, thereby the hydroelectric generator 10 generates electricity.

[0049] The hydroelectric generator 10 is disposed in the floating block 11 so that the floating block 11 and the hydroelectric generator 10 are combined, so that the center of gravity is inside the floating block 11 , which is conducive to the floating block 11 moving up and down along the sliding groove 12 .

[0050] Optionally, the hydroelectric generator 10 may also be arranged above the floating block 11. Specifically, those skilled in the art may make different arrangements according to actual needs, and the present invention does not impose any limitation thereto.

[0051] In the embodiment provided by the present invention, a through groove is provided at the upper end of the water baffle 1, the through groove penetrates both sides of the water baffle 1, and the through groove is connected to the sliding groove 12, a suspended baffle 13 is provided in the through groove, and suspended protrusions 14 are provided on both sides of the bottom of the suspended baffle 13 along the width direction.

[0052] It is understandable that when it rains, the water level of the river will rise. If a relatively high water retaining board 1 is used, the upper part of the water retaining board 1 will not be used in non-rainy days, and because the water retaining board 1 is relatively high, it will also affect the lifting of the crane. If a relatively short water retaining board 1 is used, it will not be able to cope with the problem of rising water levels during rains, and workers are required to raise it. At night, the river water may cross the water retaining board 1 and enter the construction area due to untimely raising. Even if it can be raised in time, there are certain safety hazards, especially at night.

[0053] By providing the suspended baffle 13, the buoyancy is utilized to make the suspended baffle 13 rise, thereby increasing the water retaining height of the water retaining plate 1. Meanwhile, the suspended baffle 13 is retracted inside the water retaining plate 1, thus saving space for transportation.

[0054] In the embodiment provided by the present invention, the suspension baffle 13 needs to have good buoyancy, the suspension baffle 13 is a hollow structure, and the material density of the suspension baffle 13 is less than the density of water.

[0055] In the embodiment provided by the present invention, a plurality of magnets 15 are provided on the suspension protrusion 14, and limit blocks 16 are provided on both sides of the upper opening of the through groove along the width direction, and a plurality of iron blocks 17 are provided below the limit blocks 16, and the positions of the plurality of iron blocks 17 correspond one-to-one to the positions of the plurality of magnets 15, so that the magnets 15 can absorb the iron blocks 17.

[0056] It can be understood that when the water level is close to the highest point of the water baffle 1, most of the suspended baffle 13 is outside the water baffle 1, which makes the suspended baffle easy to shake, resulting in poor water-blocking effect. Therefore, the suspended baffle 13 is fixed by adsorption of the magnet 15 and the iron block 17 to prevent the suspended baffle 13 from shaking, thereby increasing the stability of the suspended baffle 13.

[0057] At the same time, the magnet 15 and the iron block 17 are detachably connected, so that the suspension baffle 13 can be retracted into the water baffle 1 again to achieve repeated use.

[0058] In the embodiment provided by the present invention, a sealing gasket is provided on the suspension protrusion 14 and is located above a plurality of magnets 15 .

[0059] It is understandable that if the connection between the suspension baffle 13 and the limit block 16 is not sealed, river water can easily enter the construction area through the gap there.

[0060] In the embodiment provided by the present invention, an alarm bell 18 is provided above the limit stopper 16, and the alarm bell 18 is connected to the hydroelectric generator 10 and the iron block 17 respectively. When the magnet 15 is adsorbed to the iron block 17, the alarm bell 18 starts to alarm.

[0061] It is understandable that when the water level is too high, an alarm can be sounded through the alarm bell 18 so that construction workers can respond in time to avoid potential safety hazards.

[0062] It should be noted that the switch of the alarm bell 18 is the adsorption of the magnet 15 and the iron block 17, that is, when the two are adsorbed, the alarm bell 18 is turned on to alarm.

[0063] In the embodiment provided by the present invention, both sides of the through slot are provided with limiting slots 19 along the height direction, and the suspension protrusion 14 is slidably matched with the limiting slots 19 at corresponding positions, so that the suspension baffle 13 moves up and down.

[0064] It can be understood that the limiting groove 19 is provided to prevent the suspension baffle 13 from tilting and getting stuck on the two side walls of the through groove, which causes the suspension baffle 13 to be unable to rise.

[0065] In the embodiment provided by the present invention, when water is blocked, the connecting plates 20 between the multiple water blocking plates 1 can be connected by bolts to increase the water blocking width, and the two outermost water blocking plates 1 are closed by the side plates 21.

[0066] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0067] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and equivalent scope, the present invention is not limited to the specific details and the illustrations shown and described here.
