Description

Technical Field

[0001] The utility model relates to the technical field of steel gates, in particular to a corrosion-resistant steel gate for treating sewage. Background Art

[0002] Gates are control facilities used to close and open discharge channels. They are an important component of hydraulic structures and can be used to intercept water flow, control water levels, regulate flow, discharge sediment and floating objects, etc. At the same time, gates are generally made of steel structures.

[0003] The steel gates used in the existing technology for treating sewage have the following disadvantages: 1. They are not resistant to corrosion and cannot be cleaned, making them more susceptible to corrosion; 2. When a large water flow impacts the end of the steel gate close to the sewage, it will be damaged. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a corrosion-resistant steel gate for treating sewage, which solves the problems raised by the current background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A corrosion-resistant steel gate for treating sewage, comprising a fixed mounting frame, a gate body, and a cleaning scraper. A driving motor is mounted on the top of the fixed mounting frame, a lifting screw is mounted on the output end of the driving motor, and the lifting screw is threadedly connected to the gate body. Sliding grooves are provided on both sides of the interior of the fixed mounting frame, and the sliding grooves are movably connected to the gate body. A sealing seat is fixedly mounted on the bottom end of the interior of the fixed mounting frame.

[0007] Preferably, a concrete layer is provided on the periphery of the gate body, a high manganese steel layer is provided on the periphery of the concrete layer, and a chrome-plated layer is coated on the periphery of the high manganese steel layer.

[0008] Preferably, a symmetrical fixing block is fixedly installed at the middle end of the front side of the fixed installation frame, a cleaning scraper is installed on one side of the fixing block through a fixing bolt, and one side of the cleaning scraper contacts the gate body.

[0009] Preferably, a plurality of shock-absorbing springs are installed at the lower end of the front surface of the fixed installation frame, a damper is provided inside the shock-absorbing spring, and a filter plate is installed on one side of the shock-absorbing spring.

[0010] Preferably, the filter plate is in an inverted triangle shape, and the surface of the filter plate is coated with a corrosion-resistant layer.

[0011] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0012] The utility model provides a corrosion-resistant steel gate for treating sewage. The gate body, concrete layer, high manganese steel layer and chrome plating layer cooperate with each other to avoid direct contact between sewage and the gate body, thereby improving the strength and corrosion resistance of the gate body and other effects, thereby increasing the service life of the gate body. At the same time, a cleaning scraper is provided. By starting the driving motor, the driving motor drives the lifting screw to rotate, so that when the gate body moves up and down, the cleaning scraper and the gate body move relative to each other, and the cleaning scraper scrapes off the stains and impurities adsorbed on the surface of the gate body, thereby reducing the corrosion of the gate body by impurities and stains, and further increasing the service life of the gate body.

[0013] The utility model is provided with an inverted triangle-shaped filter plate, which filters impurities in sewage through the filter plate, thereby preventing the impurities in the sewage from directly causing corrosion and other damage to the gate body. At the same time, when water flow or debris impacts the gate body, the inverted triangle-shaped filter plate can disperse the impact of the water flow or debris, and the remaining water flow or debris exerts impact force on the filter plate. The filter plate squeezes the shock-absorbing spring and the damper, thereby further playing a buffering and shock-absorbing role on the gate body, thereby reducing damage to the gate body and extending the service life of the gate body.

[0019] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] According to an embodiment of the present utility model, a corrosion-resistant steel gate for treating sewage is provided.

[0021] Example 1:

[0022] As shown in the attached figure of the instruction manual Figure 1 As shown, a corrosion-resistant steel gate for treating sewage includes a fixed mounting frame 1, a gate body 4, and a cleaning scraper 8. A driving motor 2 is installed on the top of the fixed mounting frame 1, and a lifting screw 3 is installed on the output end of the driving motor 2. The lifting screw 3 is threadedly connected to the gate body 4. Sliding grooves 5 are provided on both sides of the interior of the fixed mounting frame 1, and the sliding grooves 5 are movably connected to the gate body 4. A sealing seat 6 is fixedly installed on the bottom end of the interior of the fixed mounting frame 1.

[0023] The filter plate 11 is made of chromium-molybdenum alloy steel. The surface of the filter plate 11 is coated with a corrosion-resistant layer to improve the corrosion resistance and wear resistance of the filter plate 4, thereby increasing the service life of the filter plate 4.

[0024] Example 2:

[0025] As shown in the attached figure of the instruction manual Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a corrosion-resistant steel gate for treating sewage, when in use, is provided with a gate body 4, a concrete layer 41, a high manganese steel layer 42, and a chrome-plated layer 43. The interaction prevents direct contact between sewage and the gate body 4, improves the strength and corrosion resistance of the gate body 4, and thus increases the service life of the gate body 4. At the same time, by providing an inverted triangular filter plate 11, impurities in the sewage are filtered and processed by the filter plate 11, preventing the impurities in the sewage from directly causing corrosion and other damage to the gate body 4. At the same time, when water flow or debris impacts the gate body 4, the inverted triangular filter plate 11 can disperse the impact of the water flow or debris. The remaining water flow or debris exerts an impact force on the filter plate 11, and the filter plate 11 compresses the shock-absorbing spring 9 and the damper 10, thereby further buffering and absorbing the gate body 4, thereby reducing damage to the gate body 4 and extending the service life of the gate body 4.

[0026] When the gate body 4 needs to be cleaned, the drive motor 2 is started, and the drive motor 2 drives the lifting screw 3 to rotate, so that the gate body 4 moves up and down, and the cleaning scraper 8 and the gate body 4 move relative to each other. The cleaning scraper 8 scrapes off the stains and impurities adsorbed on the surface of the gate body 4, thereby reducing the corrosion of the gate body 4 by impurities and stains, and further improving the service life of the gate body 4.
