Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, and in particular to a seepage-proof structure applied to water conservancy and hydropower construction. Background Technology

[0002] Water seepage prevention is a core aspect of water conservancy and hydropower construction, directly determining the quality, safety, and service life of the project. Inadequate water seepage control during construction can easily lead to serious hidden dangers. For example, during dam construction, rainwater intrusion can erode uncured concrete, causing structural loosening and reduced strength, threatening the stability of the construction period. Drainage channels have become the mainstream water seepage prevention facility during construction due to their convenient construction and controllable cost. They guide rainwater to be discharged in a concentrated manner through pre-set channels, cutting off the seepage path. However, existing drainage channels have obvious defects in complex environments, and their water seepage prevention effect is limited, especially in mountainous areas with dense vegetation.

[0003] When constructing in mountainous areas, existing technologies often encounter debris such as leaves and branches that easily fall and accumulate, causing blockages at the top of drainage channels. Furthermore, existing drainage channels lack an active cleaning mechanism, relying solely on manual inspections. In the event of sudden rainfall or delayed cleaning, the inlets can become clogged, preventing rainwater from entering the channels and causing surface water accumulation. This not only interferes with construction and causes materials to become damp, but can also seep into deeper structures through gaps, leading to foundation settlement and other problems. In addition, some drainage channels are made of lightweight materials such as plastic, which are easily damaged by wild animals or mechanical impacts outdoors, allowing rainwater to leak through the damaged areas and rendering them ineffective at preventing water seepage.

[0005] In view of the problems existing in the above and / or existing seepage prevention structures applied in water conservancy and hydropower construction, this utility model is proposed.

[0006] Therefore, the problem to be solved by this utility model is how to address the lack of an active cleaning mechanism for drainage channels and the fact that drainage channels made of lightweight materials such as plastic are easily damaged by wild animals or mechanical collisions outdoors.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1, referring to Figures 1-7 This is the first embodiment of the present invention. This embodiment provides a seepage-proof structure for water conservancy and hydropower construction, including: a main structure 1, including a drainage pipe 11, the top of which is connected to a drainage trough 12, and a filter plate 13 is provided on the top of the drainage trough 12; an anti-clogging component 2, including an electric push rod 21 hinged to one side of the inner cavity of the drainage trough 12, a movable plate 22 hinged to the telescopic rod of the electric push rod 21, a rotating shaft 23 fixedly connected to the surface of the movable plate 22, both sides of the rotating shaft 23 being rotatably connected to the inner cavity of the drainage trough 12, a toggle plate 24 fixedly connected to the surface of the rotating shaft 23, a trigger 25 provided at the bottom of the filter plate 13, and a filter element 26 provided at the top of the drainage pipe 11.

[0031] The drainage pipe 11 serves as the drainage terminal channel, providing a discharge path for the collected rainwater and preventing it from stagnating in the construction area. The drainage trough 12 connected to the top of the drainage pipe 11 expands the rainwater collection range, efficiently collecting rainwater from the surrounding area of ​​the construction area, meeting the basic requirement of "pre-set ditch guiding rainwater" mentioned in the background, while also optimizing collection efficiency. The filter plate 13 installed on the top of the drainage trough 12 is the first line of defense against blockage, initially intercepting large debris such as leaves and branches, reducing the probability of debris directly entering the drainage trough 12 and drainage pipe 11, and alleviating the problem of "debris accumulation clogging the inlet" mentioned in the background.

[0032] An electric push rod 21, hinged to one side of the drainage trough 12, serves as the power source, providing driving force for the anti-clogging action. The movable plate 22, hinged to its telescopic rod, converts the linear motion of the electric push rod 21 into the rotational motion of the rotating shaft 23 through a linkage, achieving efficient power transmission. The rotating shaft 23 is rotatably connected to the drainage trough 12 on both sides, ensuring the stability of the rotational action. The fixed actuating plate 24 on its surface can directly act on the debris accumulated on the filter plate 13, breaking up the blockage through mechanical actuation. The trigger 25 at the bottom of the filter plate 13 enables automatic detection of blockages, avoiding the lag of relying on manual inspections and solving the problem of "sudden rainfall or untimely cleaning leading to blockage" mentioned in the background. The filter element 26 at the top of the drainage pipe 11 serves as a second line of defense against blockages, intercepting small debris missed by the filter plate 13, further ensuring the smooth flow of the drainage pipe 11, forming a "dual filtration + active cleaning" anti-clogging system, fundamentally improving the reliability of water seepage prevention.

[0033] The working principles of the first connecting electrode 254 and the second connecting electrode 255 are existing technologies, which are clearly known to those skilled in the art, and will not be elaborated here.

[0034] Example 2, refer to Figures 1-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the trigger 25 includes a slide bar 251 fixedly connected to the bottom of the filter plate 13, and a spring 252 fixedly connected to the bottom of the slide bar 251.

[0036] When water accumulates due to blockage in the filter plate 13, the pressure is transmitted to the slide rod 251 through the filter plate 13. The spring 252 fixed at the bottom of the slide rod 251 has an elastic reset function. Its elastic deformation is positively correlated with the pressure on the filter plate 13. During normal drainage, the spring 252 is in its natural state, and the slide rod 251 is in a stable position. When the filter plate 13 is blocked, the water accumulation increases and the pressure increases. The spring 252 is compressed, which drives the slide rod 251 to move downward, thereby converting the pressure signal generated by the blockage into a mechanical displacement signal.

[0037] Specifically, the bottom of the spring 252 is fixedly connected to a sliding sleeve 253, which is slidably connected to the sliding rod 251, and the bottom of the sliding sleeve 253 is fixedly connected to the drainage groove 12.

[0038] The sliding sleeve 253 fixed at the bottom of the spring 252 is slidably connected to the slide rod 251, providing guidance for the up and down movement of the slide rod 251, preventing the slide rod 251 from deviating or jamming during the downward movement under force, and ensuring the smooth conversion of pressure signal to displacement signal.

[0039] Specifically, a first connecting electrode 254 is fixedly connected to one side of the bottom of the filter plate 13. The bottom of the first connecting electrode 254 penetrates the drainage groove 12 and extends into the side wall of the drainage groove 12. A second connecting electrode 255 is fixedly connected to the bottom of the inner cavity of the side wall of the drainage groove 12 and cooperates with the electric push rod 21.

[0040] The first connecting electrode 254 and the second connecting electrode 255, which are fixed to one side of the bottom of the filter plate 13, cooperate with each other to form a control switch for the circuit to be turned on and off. During normal drainage, the spring 252 is in its natural state, the first connecting electrode 254 and the second connecting electrode 255 are in a separated state, and the electric push rod 21 is not activated. When the filter plate 13 is blocked, causing the water pressure to increase, the slide rod 251 drives the first connecting electrode 254 to move down synchronously until it contacts the second connecting electrode 255. At this time, the circuit is connected, and the electric push rod 21 is activated as an actuator to carry out the cleaning action.

[0041] Specifically, a collection frame 14 is fixedly connected to the surface of the filter plate 13. There are two sets of collection frames 14, which are symmetrically distributed on both sides of the filter plate 13.

[0042] Two sets of symmetrically distributed collection frames 14 fixed on the surface of the filter plate 13 can temporarily store the leaves, twigs and other debris that are knocked down by the agitator 24, preventing the debris from accumulating again on the surface of the filter plate 13 or at the inlet of the drain trough 12, forming a continuous "cleaning-storage" process; the symmetrical distribution design is adapted to the swing direction of the agitator 24, ensuring that no matter which side the agitator 24 swings to, the debris that is cleaned down can be collected by the collection frame 14 on the corresponding side.

[0043] Specifically, the surface cover of the electric push rod 21 is provided with a rain shield 15, which is fixedly connected to the inner cavity of the drainage groove 12.

[0044] The rain shield 15 covering the surface of the electric push rod 21 is fixedly connected to the inner cavity of the drainage channel 12, forming a closed protective space that can directly block rainwater, dew, etc. from entering the interior of the electric push rod 21.

[0045] Specifically, the filter element 26 includes a bracket 261 fixedly connected to the inner cavity of the drain pipe 11. A motor 262 is provided on the top of the bracket 261 and cooperates with the second connecting electrode 255. The output shaft of the motor 262 is fixedly connected to the filter cover 263.

[0046] The bracket 261 fixed inside the drain pipe 11 provides a stable mounting carrier for the motor 262, ensuring the stability of the motor 262 during operation. The motor 262 cooperates with the second connecting electrode 255 to realize the linkage control with the anti-blocking component 2. When the first connecting electrode 254 contacts the second connecting electrode 255 to start the electric push rod 21, the motor 262 starts synchronously without the need for an additional triggering mechanism, simplifying the control process.

[0047] Specifically, the filter cover 263 is conical and is placed on top of the drain pipe 11.

[0048] The cone-shaped filter cover 263 increases the contact area with the water flow, which can intercept small debris more efficiently. At the same time, the tilt angle of the cone surface makes it difficult for debris to adhere and facilitates its removal under centrifugal force.

[0049] Specifically, the surface cover of the motor 262 is provided with a waterproof housing 264, which is fixedly connected to the bracket 261.

[0050] The waterproof outer shell 264 covering the surface of the motor 262 is fixedly connected to the bracket 261 to form a sealed protective structure, which can effectively prevent rainwater, water vapor and other substances from entering the interior of the motor 262.

[0051] Specifically, the surface of the drain pipe 11 is covered with a metal square tube 16, which is fixedly connected to the bottom of the drain trough 12.

[0052] The metal square tube 16 forms a comprehensive protective enclosure for the drainage pipe 11. Compared with lightweight materials such as plastic and thin iron sheet, metal has higher strength and wear resistance, which can effectively resist the tearing of wild animals, the collision of construction machinery and the corrosion of extreme outdoor environments, and prevent the drainage pipe 11 from being broken, deformed or damaged.

[0053] Working principle: During the construction of water conservancy and hydropower projects, rainwater and surface runoff flow to the drainage ditch 12. First, the filter plate 13 initially intercepts large debris such as leaves and dead branches. The filtered rainwater enters the drainage ditch 12 and is then filtered a second time by the filter element 26 at the top of the drainage pipe 11 before being discharged, thus achieving the basic seepage prevention function. When the filter plate 13 becomes blocked due to the accumulation of debris, rainwater accumulates in the filter plate 13 and the collection frame 14. The pressure generated drives the slide rod 251 at the bottom of the filter plate 13 to slide downward along the sliding sleeve 253, while simultaneously compressing the spring 252 at the bottom of the slide rod 251. During the downward movement of the slide rod 251, the first connecting electrode 254 at its bottom descends synchronously. When the first connecting electrode 254 contacts the second connecting electrode 255, the circuit is connected, triggering the anti-blocking component 2 and the filter element 26 to start.

[0054] After the circuit is connected, the electric push rod 21 hinged to one side of the inner cavity of the drainage trough 12 is activated. Its telescopic rod extends and retracts, driving the hinged movable plate 22 to move. The movable plate 22 drives the surface-fixed rotating shaft 23 to rotate around the inner cavity of the drainage trough 12. When the rotating shaft 23 rotates, it drives the surface-fixed actuating plate 24 to swing back and forth. The actuating plate 24 extends out of the filter plate 13, moving the debris accumulated on the filter plate 13 to the collection frames 14 symmetrically distributed on both sides for temporary storage. At the same time, the second connecting electrode 255 drives the inner cavity of the drainage pipe 11 to support the... The motor 262 on the frame 261 starts, and the output shaft of the motor 262 drives the conical filter cover 263 to rotate. The filter cover 263 intercepts small debris passing through the filter plate 13, and the centrifugal force generated by the rotation throws the debris into the drainage tank 12 for temporary storage. The rain shield 15 on the surface of the electric push rod 21 and the waterproof shell 264 on the surface of the motor 262 respectively protect the two from rain and ensure their stable operation. The metal square tube 16 on the surface of the drain pipe 11 protects the drain pipe 11 to prevent it from being damaged.

[0055] Once the debris on the filter plate 13 has been cleaned and the accumulated water has been drained, the spring 252 returns to its original position, causing the slide bar 251 to move upward. The first connecting electrode 254 separates from the second connecting electrode 255, the circuit is disconnected, and the electric push rod 21 and the motor 262 stop working, completing one automatic anti-clogging cycle.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
