Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, specifically relating to an energy-saving and environmentally friendly steel dam. Background Technology

[0002] A steel dam is an overflow dam consisting of a bottom-shaft driven flap gate. After prolonged use, the supporting steel plates of existing steel dams are subject to impacts from various debris, causing damage. Installing an interceptor plate in front of the supporting steel plate can protect it. However, the current interceptor plate cannot provide all-around protection for the supporting steel plate. When the supporting steel plate is in a horizontal position, a lot of debris will accumulate on the interceptor plate, reducing its lifespan. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an energy-saving and environmentally friendly steel dam, which solves the technical problems of incomplete interception and short lifespan of the current interception plates.

[0004] To solve the above problems, the technical solution of this utility model is: an energy-saving and environmentally friendly steel dam, comprising:

[0005] Fixed platform;

[0006] A supporting steel plate, one end of which is rotatably connected to a fixed platform;

[0007] The drive mechanism is mounted on a fixed platform and is connected to the support steel plate to drive the support steel plate to rotate to the vertical and horizontal positions.

[0008] The first interceptor plate is installed on the front of the supporting steel plate, and the first interceptor plate covers the front of the supporting steel plate;

[0009] The second interceptor plate has one end fixedly connected to the bottom end of the first interceptor plate, and the first and second interceptor plates form an L-shaped plate.

[0010] The third interceptor plate has one end rotatably connected to the side of the second interceptor plate opposite to the first interceptor plate via a connector, and the other end of the third interceptor plate contacts the surface of the fixed platform, forming a sloping structure.

[0011] Furthermore, the connector is a connecting shaft, which is horizontally mounted on the second interceptor plate, and the third interceptor plate is rotatably connected to the connecting shaft.

[0012] Furthermore, a counterweight is fixedly installed at the lower part of the third interceptor plate so that the other end of the third interceptor plate contacts the surface of the fixed platform.

[0013] Furthermore, the end of the third interceptor plate that contacts the fixed platform has a wedge-shaped structure.

[0014] Furthermore, the first interceptor plate is perpendicular to the second interceptor plate. When the supporting steel plate is in a vertical position, the first interceptor plate is in a vertical position and the second interceptor plate is in a horizontal position; when the supporting steel plate is in a horizontal position, the second interceptor plate is in a vertical position.

[0015] Furthermore, a limiting groove is provided on the supporting steel plate, and a limiting plate is provided on the first intercepting plate, with the limiting plate cooperating to limit the movement within the limiting groove.

[0016] Furthermore, the first interceptor plate and the supporting steel plate are elastically connected by a buffer assembly.

[0017] Furthermore, the buffer assembly includes several springs arranged in a row in the limiting groove. One end of each spring contacts the bottom wall of the limiting groove, and the other end of each spring is fixedly connected to a slider, which contacts the limiting plate.

[0018] Furthermore, the installation opening of the limiting groove is sealed by a sealing plate, which is fixed to the opening of the limiting groove with fasteners.

[0019] Furthermore, the drive mechanism is a hydraulic cylinder.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model employs a combination of a first intercepting plate, a second intercepting plate, and a third intercepting plate to achieve a wider interception range for debris. The second intercepting plate protects the first intercepting plate, while the third intercepting plate intercepts debris from below the supporting steel plate, ensuring the normal rotation of the supporting steel plate and improving the stability of the steel dam.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0027] Example: Figures 1-3 As shown, this embodiment provides an energy-saving and environmentally friendly steel dam, including a fixed platform 1, a supporting steel plate 11, a driving mechanism 12, a first intercepting plate 2, a second intercepting plate 3, and a third intercepting plate 4; one end of the supporting steel plate 11 is rotatably connected to the fixed platform 1; the driving mechanism 12 is installed on the fixed platform 1 and connected to the supporting steel plate 11 to drive the supporting steel plate 11 to rotate to a vertical position and a horizontal position; the first intercepting plate 2 is installed on the front of the supporting steel plate 11 and covers the front of the supporting steel plate 11; one end of the second intercepting plate 3 is fixedly connected to the bottom end of the first intercepting plate 2, and the first intercepting plate 2 and the second intercepting plate 3 form an L-shaped plate; one end of the third intercepting plate 4 is rotatably connected to the side of the second intercepting plate 3 opposite to the first intercepting plate 2 through a connector 5, and the other end of the third intercepting plate 4 is in contact with the surface of the fixed platform 1, and the third intercepting plate 4 forms a slope structure.

[0028] With the above configuration, the second interceptor plate 3 is located at the bottom of the first interceptor plate 2. When the supporting steel plate 11 is in a horizontal position, the second interceptor plate 3 plays the role of intercepting debris, preventing debris from accumulating on the first interceptor plate 2 and causing damage to the first interceptor plate 2, and making cleaning easier. In addition, the second interceptor plate 3 can be set at both ends of the first interceptor plate 2, which will have a better interception effect on debris. The setting of the third interceptor plate 4 prevents debris from entering the lower part of the supporting steel plate 11 and affecting the normal rotation of the supporting steel plate 11, thus improving the stability of the supporting steel plate 11. The third interceptor plate 4 is rotatably set at the lower part of the second interceptor plate 3. During the rotation of the supporting steel plate 11, the third interceptor plate 4 is always in a slope state, which has a wider interception range and a better interception effect.

[0029] In this embodiment of an energy-saving and environmentally friendly steel dam, the connecting member 5 is a connecting shaft, which is horizontally mounted on the second intercepting plate 3, and the third intercepting plate 4 is rotatably connected to the connecting shaft. This configuration results in a simple structure and stable rotation.

[0030] In this embodiment of an energy-saving and environmentally friendly steel dam, a counterweight 41 is fixedly installed at the lower part of the third interception plate 4 so that the other end of the third interception plate 4 contacts the surface of the fixed platform 1. This arrangement increases the weight of the third interception plate 4, ensuring that one end of the third interception plate 4 is always in contact with the fixed platform 1 to form a slope.

[0031] In this embodiment of an energy-saving and environmentally friendly steel dam, the end of the third interceptor plate 4 that contacts the fixed platform 1 is a wedge-shaped structure 42. The use of the wedge-shaped structure 42 reduces flow resistance and the impact force on the third interceptor plate 4.

[0032] In this embodiment of an energy-saving and environmentally friendly steel dam, the first intercepting plate 2 and the second intercepting plate 3 are perpendicular. When the supporting steel plate 11 is in a vertical position, the first intercepting plate 2 is in a vertical position and the second intercepting plate 3 is in a horizontal position; when the supporting steel plate 11 is in a horizontal position, the second intercepting plate 3 is in a vertical position. This arrangement provides a better interception effect for debris.

[0033] In this embodiment of an energy-saving and environmentally friendly steel dam, a limiting groove 111 is provided on the supporting steel plate 11, and a limiting plate 21 is provided on the first intercepting plate 2. The limiting plate 21 is fitted and limited in the limiting groove 111. This arrangement facilitates the detachable installation of the first intercepting plate 2.

[0034] In this embodiment of an energy-saving and environmentally friendly steel dam, the first intercepting plate 2 and the supporting steel plate 11 are elastically connected by a buffer assembly 6. This arrangement reduces the impact force of the first intercepting plate 2 on the supporting steel plate 11, thus protecting the supporting steel plate 11.

[0035] In this embodiment of an energy-saving and environmentally friendly steel dam, the buffer assembly 6 includes several springs 61 arranged in a row in the limiting groove 111. One end of each spring 61 contacts the bottom wall of the limiting groove 111, and the other end of each spring 61 is fixedly connected to a slider 62, which contacts the limiting plate 21. This arrangement, with several springs 61 elastically connecting the supporting steel plate 11 and the first intercepting plate 2, results in a simple structure and good buffering effect. The slider 62 facilitates the installation of the limiting plate 21 in the limiting groove 111 through its mounting opening, reducing installation resistance.

[0036] In this embodiment of an energy-saving and environmentally friendly steel dam, the installation opening of the limiting groove 111 is sealed by a sealing plate 7, which is fixed to the opening of the limiting groove 111 with fasteners. The sealing plate 7 prevents the limiting plate 21 from detaching from the limiting groove 111, thereby improving the installation stability of the first intercepting plate 2.

[0037] In this embodiment of an energy-saving and environmentally friendly steel dam, the drive mechanism 12 is a hydraulic cylinder. It has a simple structure and provides stable control over the rotation of the supporting steel plate 11.
