Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering equipment technology, specifically to a modular water-retaining dam structure for water conservancy engineering. Background Technology

[0002] Water conservancy projects are engineering projects built to prevent and control water disasters and develop and utilize water resources. They include water-related projects such as flood control, drainage, irrigation, water supply, hydropower generation, navigation, water resource protection, soil and water conservation, as well as aquaculture, tourism and ecological environment improvement. During the construction of water conservancy projects, dams are often used. Dams are usually made of reinforced concrete and use the dam-shaped concrete to block the flow of water in the river to meet the different needs of water conservancy projects.

[0003] The Chinese utility model patent with authorization announcement number "CN220503794U" specifically describes a "prefabricated steel structure water-retaining dam" in which the connecting rod and the through hole groove are sleeved to maintain the position of the main baffle, the ground locking cone penetrates into the soil through the limiting groove to lock the position, and the trapezoidal pad reduces the impact force of the water flow and increases its stability.

[0004] Although the aforementioned dams are assembled into large water-retaining dams through modular design, the lack of sealing structure between the individual water-retaining plates makes it easy for river water to flow out from between the two water-retaining plates or from the gaps at the bottom of the water-retaining plates, affecting the dam's ability to block the river. In addition, the dam is only supported from the rear side of the water-retaining plates, and the river silt is soft, resulting in poor stability. Therefore, we propose a modular water-retaining dam structure for water conservancy projects. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a modular dam structure for water conservancy projects, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a modular dam structure for water conservancy projects, including:

[0008] The frame has T-shaped grooves that are evenly spaced on its outer side;

[0009] A water baffle is provided on the outside of the frame, and a T-shaped strip adapted to the T-slot is fixedly connected to the outside of the water baffle.

[0010] A sealing mechanism is provided inside the frame. The sealing mechanism includes a movable plate, which is located inside the frame. A spring is fixedly connected to the other side of the movable plate. An installation strip is fixedly connected to the other end of the spring. A water-stop strip is fixedly connected to the other side of the installation strip. A U-shaped cover is fixedly connected to the bottom of the frame. An L-shaped hollow rubber strip is provided inside the U-shaped cover.

[0011] The limiting component includes a counterweight seat, which is disposed on the outside of the frame. A base plate is fixedly connected to the bottom of the counterweight seat, and lateral support rods are fixedly connected to both sides of the frame.

[0012] Furthermore, a threaded rod is movably connected to the outer side of the movable plate via a bearing, and a U-shaped plate is threadedly connected to the outer side of the threaded rod, with the U-shaped plate fixedly connected to the outer side of the frame.

[0013] Furthermore, a limiting rod is fixedly connected to the side of the movable plate near the U-shaped plate, and the other end of the limiting rod passes through the U-shaped plate and is slidably connected to the U-shaped plate.

[0014] Furthermore, a sliding rod is fixedly connected to the side of the mounting strip near the spring, and the other end of the sliding rod passes through the movable plate and is slidably connected to the movable plate.

[0015] Furthermore, the two counterweights are fixedly connected by the same connecting rod, and a ground-inserting rod is fixedly connected to the bottom of the counterweight.

[0016] Furthermore, a slot is provided on the outer side of the counterweight base, and a plug is fixedly connected to the outer side of the frame, with the outer side of the plug fitting into the inner side of the slot.

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] 1. This utility model, through the setting of a sealing mechanism, allows the L-shaped hollow rubber strip to be squeezed by the gravity of the water-retaining plate after the water-retaining plate is installed. Combined with the U-shaped cover, the bottom of the water-retaining plate is sealed. Under the action of the water-stop strip, the gap between the two water-retaining plates can be sealed. By sealing the gap between the water-retaining plate and the bottom of the river channel and the gap between the two water-retaining plates respectively, the seepage of river water is prevented, ensuring the water-retaining effect of the modular water-retaining dam on the river.

[0019] 2. By setting up limiting components, this utility model provides support and fixation for the water-retaining dam from the bottom, sides and rear of the dam during installation. This ensures the stability of the dam after installation and prevents it from moving under the impact of the river, which would reduce its sealing performance. This further guarantees the blocking effect of the modular water-retaining dam on the river. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Example 1:

[0032] Reference Figure 1-5 This is the first embodiment of the present invention, which discloses a modular dam structure for water conservancy projects, comprising:

[0033] Frame 4, with T-shaped grooves 41 evenly spaced on the outer side of frame 4;

[0034] Water baffle 1 is provided on the outside of frame 4, and a T-shaped strip 11 adapted to T-slot 41 is fixedly connected to the outside of water baffle 1.

[0035] T-slot 41, together with T-strip 11, is used to install water-retaining plate 1. The modular water-retaining plate 1 facilitates the installation of the water-retaining dam, improves the construction efficiency of the water-retaining dam, and shortens the construction period of the water-retaining dam.

[0036] Sealing mechanism 2 is located inside frame 4. Sealing mechanism 2 includes movable plate 202. Movable plate 202 is located inside frame 4. A spring 208 is fixedly connected to the other side of movable plate 202. An installation strip 205 is fixedly connected to the other end of spring 208. A waterstop strip 207 is fixedly connected to the other side of installation strip 205. A U-shaped cover 209 is fixedly connected to the bottom of frame 4. An L-shaped hollow rubber strip 210 is provided inside the U-shaped cover 209.

[0037] The movement of the movable plate 202 can be achieved by the spring 208 pushing the mounting strip 205 to move, so that the waterstop 207 contacts the two adjacent waterstop plates 1, sealing the gap between the two waterstop plates 1, preventing river water from flowing out through the gap and affecting the blocking effect on the river. When the waterstop plate 1 is installed, the bottom of the L-shaped hollow rubber strip 210 is squeezed under the action of gravity, causing the gas inside to move to the other side, causing it to expand and deform, so that the waterstop plate 1 and the inner side of the U-shaped cover 209 are tightly fitted, thereby sealing the bottom of the waterstop plate 1.

[0038] Specifically, a threaded rod 201 is movably connected to the outer side of the movable plate 202 via a bearing. A U-shaped plate 203 is threadedly connected to the outer side of the threaded rod 201. The U-shaped plate 203 is fixedly connected to the outer side of the frame 4. A limiting rod 204 is fixedly connected to the side of the movable plate 202 near the U-shaped plate 203. The other end of the limiting rod 204 passes through the U-shaped plate 203 and is slidably connected to the U-shaped plate 203. The limiting rod 204 is used to limit the movement trajectory of the movable plate 202, ensuring that the movable plate 202 can only move in the back-and-forth direction, and sealing the gap between the baffle plates 1.

[0039] Rotating the threaded rod 201 can drive the movable plate 202 to move towards the water baffle 1. The spring 208 and the mounting strip 205 squeeze the waterstop 207, making it fit tightly against the two water baffles 1, thus sealing the gap between the two water baffles 1.

[0040] Specifically, a sliding rod 206 is fixedly connected to the side of the mounting strip 205 near the spring 208. The other end of the sliding rod 206 passes through the movable plate 202 and is slidably connected to the movable plate 202. Under the action of the sliding rod 206, the movement trajectory of the mounting strip 205 is limited to ensure the sealing effect of the waterstop 207 on the gap between the two water-blocking plates 1.

[0041] Example 2:

[0042] Reference Figure 1-6 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0043] Limiting component 3 includes a counterweight 301, which is located on the outside of frame 4. A base plate 306 is fixedly connected to the bottom of the counterweight 301, and lateral support rods 304 are fixedly connected to both sides of frame 4.

[0044] Under the action of the counterweight seat 301, the frame 4 is supported by counterweight from the rear side. When the water-retaining plate 1 is installed, the bottom plate 306 is inserted into the bottom of the river channel, and the lateral support rods 304 can be inserted into both sides of the river channel, thereby fixing the water-retaining dam from the rear, bottom and sides of the water-retaining plate 1 respectively, ensuring the stability of the water-retaining dam during actual use.

[0045] Specifically, the two counterweight seats 301 are fixedly connected by the same connecting rod 303, the bottom of the counterweight seat 301 is fixedly connected by a grounding rod 302, the outer side of the counterweight seat 301 is provided with a slot 307, and the outer side of the frame 4 is fixedly connected with a plug 305, the outer side of the plug 305 is adapted to the inner side of the slot 307.

[0046] The connecting rod 303 can connect the two counterweights 301. The ground-inserting rod 302 can be inserted into the river channel to limit the counterweights 301. The insert block 305 and the slot 307 connect the frame 4 to the counterweights 301 and support the frame 4.

[0047] The remaining structure is the same as that in Example 1.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
