Description

Technical Field

[0001] This utility model relates to the field of watershed pollution control technology, specifically to an interception embankment for controlling non-point source pollution in ecologically clean small watersheds. Background Technology

[0002] In the ecological clean watershed management, non-point source pollution is a key factor affecting water quality. Traditional interception facilities mostly use fixed dams, which can effectively intercept suspended impurities in the water. However, over long-term operation, the intercepted debris easily accumulates and clogs the water, reducing flow capacity and increasing the difficulty and frequency of maintenance and cleaning. In addition, existing facilities often lack efficient impurity separation and collection mechanisms, allowing pollutants to potentially re-enter the water body and affecting the final treatment effect. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a reasonably designed and easy-to-use interception embankment for controlling non-point source pollution in ecological and clean small watersheds, which can effectively solve the aforementioned defects of the existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a dam body and a debris collection box, wherein the dam body is disposed on the side of the river channel, a feed inlet is provided on one side of the top wall of the dam body, and a debris collection box is fixed on one side of the dam body; it also includes: The support frame is set inside the feed inlet. One side of the support frame is inserted and screwed into the side wall of the dam body through a shaft. The other side of the lower side wall of the support frame is symmetrically abutted against the support plate, which is fixed to the inner wall of the feed inlet. The guide hopper is located inside the impurity collection box and below the feed inlet. The outer peripheral wall of the guide hopper is fixedly connected to the inner peripheral wall of the dam body. A cleaning box is provided through the lower side of the guide hopper. Several drainage holes are provided on one side wall of both the guide hopper and the cleaning box. An impurity cleaning mechanism is provided inside a cleaning box, and the impurity cleaning mechanism is connected to the impurity collection box. The water outlet pipe is fixed to the lower side of one side wall of the dam body, and the inner bottom wall of the water outlet pipe is set in the same plane as the inner bottom wall of the dam body. Through the above technical solution, the water flows into the dam body through the feed inlet during the flow process, and is guided by the guide hopper and enters the cleaning box. During this process, the water is discharged through the drain hole, while the water contains impurities that remain in the cleaning box. These impurities are then cleaned by the impurity cleaning mechanism, and the cleaned impurities enter the impurity collection box for easy collection. The discharged water is discharged through the outlet pipe.

[0005] As a further improvement of this utility model, the impurity cleaning mechanism includes: The spiral cleaning rod is installed in a circular cavity inside the cleaning box, which is connected to the impurity collection box. One end of the spiral cleaning rod is screwed through a side wall of the cleaning box via a bearing and then screwed into the side wall of the dam body via a bearing. The cleaning motor is fixed on the outer wall of one side of the dam body. The cleaning motor is connected to an external power source. Both the cleaning motor and the spiral cleaning rod are fitted with and fixed with transmission wheels. The transmission wheels on the spiral cleaning rod are located inside the side wall of the dam body. The two transmission wheels are connected by a transmission belt, which is set inside the side wall of the dam body. A fixing plate is screwed onto the end of the spiral cleaning rod away from the cleaning motor via a bearing, and the fixing plate is fixedly connected to the inner bottom wall of the circular cavity of the cleaning box; The above technical solution involves starting a cleaning motor, which rotates via a drive wheel. This drive wheel, through a transmission belt, causes another drive wheel to rotate, which in turn drives a spiral cleaning rod to rotate. The spiral cleaning rod then transports the impurities into the impurity collection box.

[0006] As a further improvement of this utility model, a protective cover is provided on the outside of the cleaning motor, and the protective cover is fixed on the outer wall of the dam body. The above technical solutions can protect the cleaning motor and extend its service life.

[0007] As a further improvement of this utility model, a baffle is provided on the side of the outer top wall of the water-retaining dam away from the feed inlet, and the baffle is arranged in an arc shape on the side adjacent to the feed inlet. The above technical solution can facilitate the blocking of water flow and guide the water flow through the arc-shaped surface, thus preventing the water flow from stagnating on the upper side of the dam body.

[0008] As a further improvement of this utility model, a push plate is provided on one side of the support frame. The push plate is engaged with the support frame and abuts against it. The push plate is located inside the top wall of the dam body. Several tension springs are equidistantly embedded and fixed in the notches on the front and rear sides of the push plate. The tension springs are fixed on the inner wall of one side of the top wall of the dam body. A pressure plate abuts against the inclined surface of the inner side of the push plate. The upper side of the pressure plate passes through the top wall of the dam body and is exposed on the upper side of the dam body. With the above technical solution, when it is necessary to flip the support frame upward to clean the inside of the dam, the pressure plate is pushed downward. The pressure plate drives the push plate to move to one side of the support frame through its inclined surface. The inclined surface on the other side of the push plate pushes the support frame, thereby making the support frame rotate upward, which facilitates flipping the support frame.

[0009] As a further improvement of this utility model, a limiting plate is fixed on the top wall of the pressure plate, and the limiting plate is suspended on the upper side of the dam body; this can prevent the pressure plate from falling downward into the dam body.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The intercepting embankment for ecological clean small watershed non-point source pollution control described in this utility model can effectively separate and collect impurities in the water flow, reduce maintenance frequency, and improve the efficiency and automation level of non-point source pollution control. This utility model has the advantages of reasonable setting and low manufacturing cost. Attached Figure Description

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1: like Figures 1-4 As shown, this embodiment includes a dam body 1 and a debris collection box 2. The dam body 1 is located on the side of the river channel. An inlet 1-1 is provided on the left side of the top wall of the dam body 1. A baffle 11 is provided on the outer top wall of the dam body 1 away from the inlet 1-1. The baffle 11 is arc-shaped on the side adjacent to the inlet 1-1, which facilitates the blocking of water flow and guides the water flow through the arc shape, preventing water from stagnating on the upper side of the dam body 1. The debris collection box 2 is fixed to one side of the dam body 1. It also includes: The support frame 3 is set inside the feed inlet 1-1. One side of the support frame 3 is inserted and screwed into the side wall of the dam body 1 through a shaft. The other side of the lower side wall of the support frame 3 is symmetrically abutted against the support plate 4. The support plate 4 is welded and fixed to the inner wall of the feed inlet 1-1. The guide hopper 5 is located inside the impurity collection box 2 and below the feed inlet 1-1. The outer peripheral wall of the guide hopper 5 is fixedly connected to the inner peripheral wall of the dam body 1. A cleaning box 6 is provided through the lower side of the guide hopper 5. Several drainage holes 7 are opened on one side wall of both the guide hopper 5 and the cleaning box 6. Impurity cleaning mechanism 8 is disposed inside cleaning box 6 and is connected to impurity collection box 2. The water outlet pipe 9 is welded and fixed to the lower side of the right side wall of the dam body 1, and the inner bottom wall of the water outlet pipe 9 is set in the same plane as the inner bottom wall of the dam body 1.

[0018] Example 2: See Figure 2 , Figure 4 As shown, based on Embodiment 1, the impurity cleaning mechanism 8 includes: Spiral cleaning rod 8-1 is installed in the circular cavity inside the cleaning box 6, which is connected to the impurity collection box 2. One end of the spiral cleaning rod 8-1 passes through one side wall of the cleaning box 6 via a bearing and is then screwed into the side wall of the dam body 1 via a bearing. The cleaning motor 8-2 is fixed on the outer wall of one side of the dam body 1 and is connected to an external power source. A protective cover 10 is fitted on the outer side of the cleaning motor 8-2 and fixed on the outer wall of the dam body 1 to protect the cleaning motor 8-2 and extend its service life. Both the cleaning motor 8-2 and the spiral cleaning rod 8-1 are fitted with and fixed with transmission wheels 8-3. The transmission wheels 8-3 on the spiral cleaning rod 8-1 are located inside the side wall of the dam body 1 and are connected by a transmission belt 8-4, which is also located inside the side wall of the dam body 1. The fixing plate 8-5 is screwed onto the end of the spiral cleaning rod 8-1 away from the cleaning motor 8-2 via a bearing, and the fixing plate 8-5 is fixedly connected to the inner bottom wall of the circular cavity of the cleaning box 6.

[0019] Example 3: See Figure 2 , Figure 3As shown, based on Embodiment 1, a push plate 12 is provided on one side of the support frame 3. The push plate 12 is engaged with the support frame 3 and is located inside the top wall of the dam body 1. Several tension springs 13 are equidistantly embedded and welded into the notches on the front and rear sides of the push plate 12. The tension springs 13 are welded to the inner wall on the right side of the top wall of the dam body 1. A pressure plate 14 is engaged on the inclined surface of the inner side of the push plate 12. The upper side of the pressure plate 14 passes through the top wall of the dam body 1 and is exposed on the upper side of the dam body 1. A limiting plate 15 is welded to the top wall of the pressure plate 14 and is suspended on the upper side of the dam body 1. This prevents the pressure plate 14 from falling downward into the dam body 1.

[0020] In using this invention, water flows into the dam body 1 through the inlet 1-1, is guided by the guide hopper 5, and enters the cleaning box 6. During this process, the water is discharged through the drain hole 7, while impurities in the water remain in the cleaning box 6. Then, the cleaning motor 8-2 is started, and the cleaning motor 8-2 rotates through its drive wheel 8-3. This drive wheel 8-3, through the action of the drive belt 8-4, causes another drive wheel 8-3 to rotate, which in turn drives the spiral cleaning rod 8-1 to rotate. The spiral cleaning rod 8-1 moves and conveys impurities into the impurity collection box 2. The cleaned impurities enter the impurity collection box 2 for easy collection. The discharged water flows out through the outlet pipe 9. When it is necessary to flip the support frame 3 upward to clean the inside of the water-blocking dam body 1, the pressure plate 14 is pushed downward. The pressure plate 14 drives the push plate 12 to move to one side of the support frame 3 through its inclined surface. The inclined surface on the other side of the push plate 12 pushes the support frame 3, thereby making the support frame 3 rotate upward, which facilitates flipping the support frame 3.

[0021] Compared with the prior art, the beneficial effects of this specific embodiment are as follows: 1. The spiral cleaning rod 8-1 driven by the motor can automatically transport the intercepted impurities to the impurity collection box 2, realizing continuous automatic cleaning of impurities and significantly reducing the frequency of manual cleaning and maintenance costs. 2. The unique design of the guide hopper 5 and the perforated cleaning box 6 allows water to be quickly discharged through the drain hole 7, while solid impurities are effectively intercepted and guided to the impurity cleaning mechanism 8, achieving effective separation of water and impurities and ensuring interception and drainage efficiency. 3. The support frame 3, together with the pressure plate 14 and the tension spring 13 mechanism, can be easily flipped open by pressing down, providing a convenient maintenance passage for the interior of the dam body 1, making it easy to clean and maintain silt or equipment; 4. The motor 8-2 is cleaned and a protective cover 10 is installed to prevent direct erosion by water flow and impurities. At the same time, the arc-shaped guide design of the baffle 11 can effectively guide the water flow, reduce the impact and stagnation on the dam body, and jointly improve the durability of the equipment.

[0022] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
