[0045] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0046] Combined with attachment Figure 1-13 , a water retaining dam for a water conservancy project, comprising:

[0047] The dam body 100 can be made of high-strength plastic or steel to ensure its stability and durability;

[0048] The dam body 100 is provided with a cavity 101 inside, and the front and rear walls of the cavity 101 are symmetrically provided with slide grooves 102, and the cavity 101 is provided with a sandwich plate 103 inside, which is made of lightweight and high-strength material. The outer periphery of the sandwich plate 103 is wrapped with a rubber layer 104 to increase sealing and wear resistance; the front and rear ends of the rubber layer 104 are symmetrically provided with slide bars 105, and the slide bars 105 and the corresponding slide grooves 102 are slidably matched; so that the sandwich plate 103 moves up and down along the slide grooves 102 to prevent dislocation, etc. The rubber layer 104 can be made of rubber used in tires, which is relatively wear-resistant, resistant to water erosion, and has a certain elasticity. In this way, when the rubber layer 104 and the inner wall of the cavity 101 are interference-fitted, it does not affect the up and down movement of the sandwich plate 103 and the rubber layer 104, and can also better prevent water leakage from the contact point between the rubber layer 104 and the cavity 101;

[0049] In order to adjust the position of the sandwich plate 103, the rear end of the dam body 100 is provided with an adjustment slot 106 that penetrates into the cavity 101. The rear end of the sandwich plate 103 is provided with a crossbar 107, which extends from the adjustment slot 106. One end of the crossbar 107 extending from the adjustment slot 106 is provided with a screw hole 108.

[0050] A support platform 109 is provided below the rear end adjustment groove 106 of the water retaining dam body 100. A bearing 110 is provided in the support platform 109. A screw 111 is provided in the bearing 110. The upper end of the screw 111 is threadedly connected to the screw hole 108. A hexagonal column 112 is provided on the screw 111.

[0051] The water retaining dam body 100 is evenly provided with a plurality of water-permeable holes 113 penetrating the water retaining dam body 100, the sandwich plate 103 and the rubber layer 104;

[0052] By rotating the hexagonal prism 112 on the screw 111 with a wrench or the like, the screw 111 can be rotated, thereby driving the cross bar 107 and the sandwich plate 103 to move up and down in the cavity 101, thereby adjusting the height of the water-permeable holes 113 on the sandwich plate 103 and the rubber layer 104, so that they are connected with the water-permeable holes 113 on the dam body 100, and then the water-permeable holes 113 are connected to form a channel for water flow, so that when setting the dam, a part of the impact force of the water flow on the dam can be unloaded, and the dam can be set more conveniently and quickly; in addition, it can ensure that excess water can be discharged when necessary while maintaining the stability of the entire dam; or it can be misaligned with the water-permeable holes 113 on the dam body 100, so that the sandwich plate 103 and the rubber layer 104 block the water-permeable holes 113 on the dam body 100, thereby closing the water flow channel;

[0053] The bottom of the water retaining dam body 100 is provided with a base frame 114, and the base frame 114 is provided with a fixing mechanism in a detachable manner; it can play a role in fixing the water retaining dam body 100;

[0054] In order to further enhance the stability of the water retaining dam, a supporting mechanism is further included. The supporting mechanism is connected to the base frame 114 and the water retaining dam body 100 in a detachable manner.

[0055] The supporting mechanism includes a base plate 201 and a suspension rod 202. A first connecting plate 203 is provided at one end of the base plate 201. A first connecting groove 204 is provided at the rear end of the base frame 114. The first connecting plate 203 cooperates with the first connecting groove 204. A first connecting ear 205 is symmetrically provided at the upper end of the base plate 201. A second connecting ear 206 is symmetrically provided at the rear end of the dam body 100. Holes are provided on the first connecting ear 205 and the second connecting ear 206, and bolts are provided in the holes. The lower end of the suspension rod 202 is rotatably connected to the first connecting ear 205 through the bolts. The upper end of the suspension rod 202 is rotatably connected to the second connecting ear 206 by a bolt; in this way, the base plate 201 can be supported on the ground and form a relatively large area of contact with the ground, thereby increasing the bearing capacity and enabling the dam body 100 to withstand greater pressure. The suspension rod 202 can easily form a support between the dam body 100 and the base plate 201, and the length can be adjusted. In this way, the length of the suspension rod 202 can be adjusted according to the degree of bending of the dam body 100, providing a more solid support for the dam body 100 and preventing the dam body 100 from being compressed and deformed.

[0056] A first fixing hole 115 is provided on the base frame 114 at a position corresponding to the first connecting groove 204 . The first fixing hole 115 passes through the base frame 114 , the first connecting plate 203 and the first connecting groove 204 , so that a bolt can be set in the first fixing hole 115 to fix the base frame 114 and the bottom plate 201 .

[0057] The fixing mechanism is a fixing plate 300, a top cover 301 is provided on the upper end of the fixing plate 300, and second connecting plates 302 are symmetrically provided on both sides of the fixing plate 300;

[0058] The base frame 114 is evenly provided with a plurality of mounting grooves 116, and a second connecting groove 117 is provided on both sides of the mounting groove 116. The fixed plug plate 300 cooperates with the mounting groove 116. In this way, for some places such as dams or muddy land formed by accumulation of soil, the fixed plug plate 300 can be inserted into the land through the mounting groove 116. On the one hand, the water retaining dam can be fixed, and on the other hand, a simple water retaining mechanism can be formed inside the land, which can prevent water from flowing out from the lower part of the water retaining dam body to a certain extent. The top cover 301 can play a limiting role to prevent the base frame 114 from sliding out from the upper end of the fixed plug plate 300. The second connecting plate 302 cooperates with the second connecting groove 117 to limit the fixed plug plate 300.

[0059] An insertion hole 118 is provided between the two mounting grooves 116 on the base frame 114. When the dam body 100 is initially set up, after the dam body 100 is placed, a steel chisel can be inserted into the ground through the insertion hole 118 to initially stabilize the dam body 100 for subsequent structural installation.

[0060] It also includes an upper water baffle 400, a limiting plate 401 is provided at the bottom of the front end of the upper water baffle 400, and a third connecting groove 402 is provided at the lower end of the upper water baffle 400;

[0061] A U-shaped fixing card 403 is provided on the front side of the upper end of the water retaining dam body 100, and a third connecting plate 404 is provided on the upper end of the water retaining dam body 100. During installation, the upper water retaining plate 400 is placed above the water retaining dam body 100, and the upper water retaining plate 400 is tilted so that the limiting plate 401 is inserted into the U-shaped fixing card 403. Then, the upper water retaining plate 400 is slowly rotated to a vertical state, and the third connecting plate 404 is inserted into the third connecting groove 402. This makes the connection more stable and the connection more airtight.

[0062] The bottom rear end of the dam body 100 and the upper rear end of the upper water retaining plate 400 are symmetrically provided with fixing parts 405, and the fixing parts 405 are provided with through holes 406. The through holes 406 are provided with fixing bolts 407 for fixing the two fixing parts 405. The upper water retaining plate 400 is fixed to the dam body 100 by using the fixing bolts 407.

[0063] One side of the upper water retaining plate 400 and one side of the water retaining dam body 100 are both provided with a slot 409, and the other side of the upper water retaining plate 400 and the other side of the water retaining dam body 100 are both provided with an inserting plate 408. The two adjacent upper water retaining plates 400 and the two adjacent water retaining dam bodies 100 are connected and matched through the inserting plate 408 and the slot 409, which can make it more convenient to connect the two water retaining dams and the connection more stable.

[0064] A plurality of holes 410 penetrating the upper water retaining plate 400 and the water retaining dam body 100 are evenly provided at positions corresponding to the slots 409 on the upper water retaining plate 400 and the water retaining dam body 100. The holes 410 penetrate the plug plate 408. Bolts can be installed in the holes 410 to fix the adjacent water retaining dams, so that the two water retaining dams form a more stable whole and can withstand greater water pressure.

[0065] The two side walls of the slot 409 are provided with waterproof sealing strips 411 with holes to prevent water leakage and provide a better seal.

[0066] When the dam is used on cement or relatively hard ground, a waterproof sealing rubber can be provided at the bottom of the dam body 100. The weight of the dam itself will press the waterproof sealing rubber, making the waterproof sealing rubber and the cement or relatively hard ground in closer contact, thereby achieving a better anti-leakage effect.

[0067] When the utility model is implemented,

[0068] Example 1, as Figure 6As shown, this state is without the upper water baffle 400, and this state can be used when the water level is not high;

[0069] For urban or other hard surfaces:

[0070] When in use, first stand the dam body 100 at the place where the dam is needed, and then hold the dam body 100 to prevent it from falling over. If the dam is set at a place with flowing water, the hexagonal column 112 can be manually screwed with a wrench. At this time, the screw 111 rotates, and then the cross bar 107 and the sandwich plate 103 can be driven to move up and down in the cavity 101, driving the sandwich plate 103 to move upward, thereby adjusting the height of the water-permeable holes 113 on the sandwich plate 103 and the rubber layer 104, so that they are connected with the water-permeable holes 113 on the dam body 100, and then the water-permeable holes 113 are connected to form a channel for water to flow, so that water can flow. Water can flow out through the water-permeable holes 113 to form a channel, thereby relieving part of the impact force of the water flow on the dam. Then, the bottom plate 201 is inserted into the first connecting groove 204 on the base frame 114 through the first connecting plate 203, and then the bolts are inserted into the first fixing holes 115 and tightened to connect and fix the bottom plate 201 and the base frame 114. Subsequently, the two ends of the suspension rod 202 are respectively installed on the first connecting ear 205 and the second connecting ear 206 by bolts, and the length of the suspension rod 202 is adjusted to make the suspension rod 202 bear force. In this way, the bottom plate 201 can be against the ground, and the suspension rod 202 forms a support for the dam body 100.

[0071] Then continue to assemble the dam body 100, connect the two adjacent dam bodies 100 through the plug plate 408 and the slot 409, and then install bolts in the holes 410 to fix the adjacent dams so that the two dams are more firmly formed into a whole. Then install the bottom plate 201, the suspension rod 202, etc. in the above-mentioned manner; after all the installation is completed or after part of the dam body 100 is installed, screw the screw 111 to lower the sandwich plate 103 so that the water holes 113 on the sandwich plate 103 and the water holes 113 on the dam body 100 are misaligned, so that the sandwich plate 103 and the rubber layer 104 block the water holes 113 on the dam body 100, close the water flow channel, and intercept the water flow;

[0072] If it is installed in advance in a place without water flow, there is no need to adjust the position of the sandwich plate 103 when setting up the dam body 100. The water holes 113 on the sandwich plate 103 and the water holes 113 on the dam body 100 are kept offset and the water flow channel is closed.

[0073] For soft surfaces such as earth embankments or other soils:

[0074] Then, the dam body 100 is placed where the dam needs to be set up, and then people hold the dam body 100 to prevent it from falling over. If the dam is to be set up in a place with flowing water, the hexagonal column 112 can be manually screwed with a wrench. At this time, the screw 111 rotates, and then the cross bar 107 and the sandwich plate 103 can be driven to move up and down in the cavity 101, driving the sandwich plate 103 to move upward, thereby adjusting the height of the water-permeable holes 113 on the sandwich plate 103 and the rubber layer 104, so that they are connected with the water-permeable holes 113 on the dam body 100, and then the water-permeable holes 113 are connected to form a channel for water flow, so that water can flow out from the water-permeable holes 113 to form a channel, thereby removing part of the impact force of the water flow on the dam; then take out the steel drill prepared in advance, and insert the steel drill into the ground from the socket 118, which can The dam body 100 is initially stabilized, and then the fixing plug plate 300 is inserted into the ground from the installation groove 116. On the one hand, it can fix the dam, and on the other hand, a simple water retaining mechanism can be formed inside the ground, which can prevent water from flowing out from the lower part of the dam body to a certain extent; then the bottom plate 201 is inserted into the first connecting groove 204 on the base frame 114 through the first connecting plate 203, and then the bolts are inserted into the first fixing holes 115 and tightened, so that the bottom plate 201 and the base frame 114 are connected and fixed; then the two ends of the suspension rod 202 are respectively installed on the first connecting ear 205 and the second connecting ear 206 by bolts, and the length of the suspension rod 202 is adjusted so that the suspension rod 202 is subjected to force, so that the bottom plate 201 can be against the ground, and the suspension rod 202 forms a support for the dam body 100;

[0075] Then continue to assemble the dam body 100, connect the two adjacent dam bodies 100 through the plug plate 408 and the slot 409, and then install bolts in the holes 410 to fix the adjacent dams so that the two dams are more firmly formed into a whole. Then install the bottom plate 201, the suspension rod 202, etc. in the above-mentioned manner; after all the installation is completed or after part of the dam body 100 is installed, screw the screw 111 to lower the sandwich plate 103 so that the water holes 113 on the sandwich plate 103 and the water holes 113 on the dam body 100 are misaligned, so that the sandwich plate 103 and the rubber layer 104 block the water holes 113 on the dam body 100, close the water flow channel, and intercept the water flow;

[0076] If it is set in advance in a place without water flow, there is no need to adjust the position of the sandwich plate 103 when setting the dam body 100. Just keep the water holes 113 on the sandwich plate 103 and the water holes 113 on the dam body 100 offset and close the water flow channel.

[0077] Example 2, as Figure 1-3 , Figure 5As shown; this state is to install the upper water baffle 400, this state can be used in the case of high water level;

[0078] For urban or other hard surfaces:

[0079] The installation method is the same as the installation method for urban ground or other hard ground in Example 1, and only the upper water retaining plate 400 needs to be installed;

[0080] During installation, place the upper water baffle 400 above the water dam body 100, tilt the upper water baffle 400, insert the limit plate 401 into the U-shaped fixing card 403, then slowly rotate the upper water baffle 400 to a vertical state, and insert the third connecting plate 404 into the third connecting groove 402, so that the connection is more stable and the connection is more airtight, then install the fixing bolts 407 in the through holes 406, and use the fixing bolts 407 to fix the upper water baffle 400 to the water dam body 100; if the water dam needs to be assembled horizontally, the two adjacent upper water baffles 400 can be connected by connecting the plug plate 408 and the slot 409, and then install the bolts in the holes 410 to fix the two upper water baffles 400;

[0081] For soft surfaces such as earth embankments or other soils:

[0082] The installation method is the same as the installation method for soft ground such as earth dam or other earth in Example 1, except that the upper water retaining plate 400 is additionally installed;

[0083] During installation, place the upper water baffle 400 above the water dam body 100, tilt the upper water baffle 400 so that the limit plate 401 is inserted into the U-shaped fixing card 403, then slowly rotate the upper water baffle 400 to a vertical state, and insert the third connecting plate 404 into the third connecting groove 402, so that the connection can be more stable and the connection is more airtight, then install the fixing bolts 407 in the through holes 406, and use the fixing bolts 407 to fix the upper water baffle 400 to the water dam body 100; if the water dam needs to be assembled horizontally, the two adjacent upper water baffles 400 can be connected by connecting the plug plate 408 and the slot 409, and then install bolts in the holes 410 to fix the two upper water baffles 400.

It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0085] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0086] In the description of the embodiments of the present invention, “a plurality of” means at least 2.

[0087] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0088] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
