Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy devices, in particular to a water gate device for a water conservancy project. Background Art

[0002] Gates are important mechanisms in water conservancy projects, used to prevent floods, hold back tides, raise water levels, etc. They are widely used in rivers, canals, reservoirs, lakes and other areas. In order to clean the debris on the gate surface, some companies add cleaning mechanisms to the original gates. Cleaning mechanisms include rollers and scrapers. Taking the scraper as an example, the scraper is generally fixed and cannot be adjusted. The scraper is worn out during the long-term lifting and lowering operation of the gate, which reduces its service life and needs to be improved. Utility Model Content

[0003] In order to solve at least one of the above technical defects, the utility model provides the following technical solutions:

[0004] The present application document discloses a water gate device for a water conservancy project, including a box body, a gate, and a lifting mechanism. An entrance is arranged at the bottom of the box body for the gate to enter a chamber. The movable end of the lifting mechanism is connected to the gate. The lifting mechanism also includes a scraper mechanism for processing the gate plate surface with the scraper mechanism. The scraper mechanism includes a scraper, an elastic member, a pulley, and a wire wheel mechanism. A mounting groove is arranged at the box wall on one side of the entrance and the scraper is hinged in the mounting groove. An elastic member is arranged between one end of the scraper and the bottom wall of the mounting groove and the other end is connected to the pulley. The other end of the pulley is connected to the wire wheel mechanism. The pulley mechanism is used to loosen or tighten the pulley to change the inclination angle of the scraper accordingly.

[0005] In this scheme, the structure of the sluice gate is improved, and the gate plate surface is cleaned by a scraper mechanism. Specifically, the pull rope is tightened by the wire wheel mechanism to tilt the scraper to a predetermined angle, and the scraper is used to scrape off debris on the gate plate surface during the process of the lifting mechanism moving the gate upward. The pull rope can be further tightened by the wire wheel mechanism when needed, so that the inclination angle of the scraper can be adjusted twice to meet the use requirements. After the pull rope is loosened by the wire wheel mechanism, the scraper is reset under the action of the elastic member, thereby reducing wear and extending the service life.

[0006] Furthermore, it also includes a fixed seat, which is arranged on the side of the box body. A wire wheel mechanism is arranged in the cavity of the fixed seat. The wire wheel mechanism includes a first driving mechanism and a wire wheel. The wire wheel is arranged at the output end of the first driving mechanism and is connected to the end of the pull rope. A fixed seat is added to install the wire wheel mechanism for easy installation.

[0007] Furthermore, it also includes a mounting seat, which is fixed in the mounting groove. The scraper is hinged on the mounting seat. One end of the elastic member is connected to the tail end of the scraper and the other end is fixed to the mounting seat. The scraper, elastic member, etc. are installed on the mounting seat to facilitate subsequent fixation in the mounting groove.

[0008] Furthermore, it also includes a guide wheel and a guide column. The guide wheel is arranged on a mounting seat below the scraper. The guide column is arranged at the end of the mounting groove. The pull rope is connected to the wire wheel mechanism after passing through the guide wheel and the guide column. Adding guide wheels, guide columns, etc. helps to improve the stability of operation.

[0009] Furthermore, the end of the scraper abutting against the gate is coated with an elastic layer to prevent the scraper from being seriously damaged by the uneven surface of the gate, thereby improving adaptability.

[0010] Furthermore, scraper mechanisms and pull ropes are provided on the box walls on both sides of the entrance, and the pull ropes are connected to the same wire wheel mechanism, which helps to simplify the structure.

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, in this example, the water conservancy project sluice device includes a box body 1, a gate 3, and a lifting mechanism 2. The box body 1 is in the shape of a rectangular box, an inlet is formed at the bottom of the box body 1 and an outlet is formed at the top. The gate 3 enters the chamber of the box body 1 from the inlet. The lifting mechanism can be selected as a cylinder type or a motor type according to needs, such as Figure 1 As shown, a motor is used to drive a rope drum to rotate, one end of a rope is fixed on the rope drum and the other end is connected to the head end of a gate, the rope drum rotates to pull the gate upward, the rope drum is rotatably connected to the outlet through a pivot, etc., and a motor is installed in a cavity of the box wall at the outlet.

[0022] In this example, a scraper mechanism is added to process the gate surface, such as scraping and cleaning debris on the gate surface. The scraper mechanism includes a scraper 7, an elastic member 9, a pull rope 11, and a wire wheel mechanism. A mounting groove 6 is preformed on the box wall on the entrance side. A mounting seat is fixed in the mounting groove 6. The mounting seat 8 is fixed with a longitudinal plate on a flat plate. An ear plate is formed in the middle of the bottom surface of the arc-shaped body of the scraper 7. The ear plate and the longitudinal plate are pivotally connected through a shaft body, etc.

[0023] An elastic member 9 is fixed on the bottom surface of the tail end of the scraper 7. The elastic member is such as a spring. The bottom end of the elastic member 9 is fixed to the mounting seat. A hole is formed on the bottom surface of the head end of the scraper 7 and the end of the pull rope 11 is fixed in the hole. The pull rope 11 is connected to the wire wheel mechanism.

[0024] In this example, a fixing seat 4 is installed at the bottom side of the box body 1. The fixing seat 4 is rectangular in shape. A wire wheel mechanism is installed in the cavity of the fixing seat 4. The wire wheel mechanism includes a first driving mechanism 14 and a wire wheel 13. The first driving mechanism is such as a motor. The wire wheel 13 is installed at the output end of the first driving mechanism 14. The wire wheel is connected to the end of the pull rope. The first driving mechanism drives the wire wheel to rotate, such as forward or reverse, so that the pull rope is tightened or loosened, and the inclination angle of the scraper changes accordingly.

[0025] In this example, mounting grooves 6 are formed on the cavity walls of the box body on both sides of the inlet, and scraper mechanisms are installed in the mounting grooves 6. The pull rope is connected to the same wire wheel.

Figure 3 As shown, the pull rope 11 is connected to the wire wheel 13 after being wound around the guide wheel 10 and the guide column 12. Under the drive of the first driving mechanism 14, the two pull ropes are tightened or loosened synchronously, and the scraper angle changes accordingly.

[0027] The end of the scraper 7 abutting against the gate is covered with an elastic layer 5, which can be formed with a desired elastic material according to demand, so that the elastic layer abuts against the plate surface of the gate to improve adaptability.

[0028] When in use, if the scraper is tilted to extend from the notch of the mounting groove, the scraper is used to clean the dirt on the plate surface during the upward movement of the gate. After the pull rope is relaxed, the scraper is reset under the pull of the elastic member.
