Description

Technical Field

[0001] This utility model relates to the field of gate technology, and in particular to a gate for water conservancy projects with a filtering function. Background Technology

[0002] Sluice gates are used to regulate water flow. They can adjust water levels to meet the needs of water storage and irrigation; control water flow to cope with flood discharge during the flood season and water replenishment during the dry season; and achieve water diversion and control in river channels to ensure water allocation in different areas.

[0003] Currently, there are water conservancy engineering gates with impurity filtering functions. Typically, a grid is installed on one side of the gate to pre-filter the water flow. It not only has the basic water control functions of traditional gates, such as regulating water level, controlling water flow, and realizing water storage, flood discharge, and water distribution, but also intercepts impurities such as tree branches, plastic waste, silt, and gravel in the water through its own filter screen or grid structure. This can protect downstream facilities such as water pumps, generator sets, and water pipelines from wear or blockage by impurities, prevent the gate opening and closing mechanism from malfunctioning due to the accumulation of impurities, and ensure the stable operation of the water conservancy system.

[0004] However, existing gate gates suffer from a decrease in water flow rate; the debris intercepted by their screens tends to adhere and accumulate, with adhering silt and fibrous impurities accumulating on one side of the screen, leading to a decrease in water flow rate. To address this, we propose a hydraulic engineering gate gate with a filtration function to solve the problems encountered by existing technologies. Utility Model Content

[0025] 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.

[0026] 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.

[0027] 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.

[0028] Example 1:

[0029] Reference Figures 1 to 5 This is the first embodiment of the present utility model. This embodiment provides a water conservancy engineering gate with a filtering function, including a gate body 2 that can be raised and lowered on the gate frame 1, and a grid 3 is provided on its front side. A sewage guide 5 is provided on one side of the grid 3. The sewage guide 5 includes a scraper 51 that is driven to rise and fall by the gate body 2. The rear side of the scraper 51 is attached to the front side of the grid 3. A flow guide groove is provided in the upper end of the scraper 51. A sewage outlet 6 is provided in the gate frame 1.

[0030] The gate frame 1 serves as the core installation carrier, providing fixed support for components such as the gate body 2 and the grid 3, and limiting the lifting range of the gate body 2 to ensure the stability of the overall structure. The gate body 2 can be raised and lowered to achieve water blocking and control functions. At the same time, it serves as the driving carrier for the scraper 51, driving the scraper 51 to move synchronously through its own lifting and lowering, connecting the water control and cleaning processes. The grid 3 is used to intercept floating objects, suspended particles and other debris in the water flow, achieving basic filtration and preventing impurities from entering downstream facilities and causing blockage or wear. The scraper 51 in the guide component 5 fits against the grid 3 and scrapes away residual debris from the grid 3 as the gate body 2 rises and falls. Its upper guide channel guides the debris into the scraper 51 for collection and discharge. The sewage outlet 6 serves as a debris discharge channel, receiving the debris transported by the scraper 51, achieving centralized discharge of impurities and preventing debris accumulation from affecting equipment operation.

[0031] Example 2:

[0032] Reference Figure 1 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, Figure 1In the gate frame 1, a driving component 4 is provided on the top wall. The driving component 4 includes a drum 42 rotatably mounted in the top opening of the gate frame 1 via bearings. A servo motor 41 is fixed on the top wall of the gate frame 1. The output end of the servo motor 41 is connected to the drum 42 via a reducer to drive the drum 42 to rotate. A steel wire rope 43 is welded to the periphery of the drum 42. After the steel wire rope 43 is wound around the drum 42, one end of it is fixed to the upper end of the gate body 2 via a lifting lug to drive the gate body 2 to rise and fall.

[0034] The servo motor 41 drives the drum 42 via a reducer, and then drives the gate body 2 to rise and fall via the wire rope 43.

[0035] Specifically, Figure 1 In the middle, the inner wall of the gate frame 1 is provided with a sliding groove, and the sliding groove is slidably disposed with both ends of the gate plate body 2;

[0036] The chute provides guidance for the gate, preventing it from shifting during lifting and lowering, ensuring the stability and sealing of the gate's opening and closing, and laying the power and structural foundation for the overall function.

[0037] Specifically, Figure 1 In the middle, the two ends of the grille 3 are fixed to the inner wall of the gate frame 1 by bolts, and the gate frame 1 is located in the lower half of the gate frame 1;

[0038] Determine the bolt fixing method and lower installation position of the screen 3 to ensure that it is firmly installed and resistant to water flow impact, while covering the main water flow channel to maximize the interception of debris, and at the same time facilitate later maintenance and realize the basic impurity filtering function.

[0039] Example 3:

[0040] Reference Figure 2 , Figure 3 , Figure 5 and Figure 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0041] Specifically, Figure 2 and Figure 5 In the middle, the scraper 51 near the sewage outlet 6 is inclined downward at one end. The high end of the scraper 51 is fixed with a bent rod 52 by bolts. The bent rod 52 passes around the upper end of the gate body 2 and is fixed to the rear side of the gate body 2 by bolts.

[0042] The inclined design of scraper 51 facilitates the accumulation of debris, and the bent rod 52 achieves a rigid connection between it and the gate, ensuring that the two rise and fall synchronously. This does not affect the gate's water blocking function and ensures the linkage of the cleaning action.

[0043] Specifically, Figure 3 In the middle, the upper surface of the scraper 51 is integrally provided with multiple comb teeth 53 for fitting with the front side of the grille 3;

[0044] The comb teeth 53 can push short branches off, remove attached fine impurities, improve the cleanliness of the grid 3, prevent grid holes from clogging, and ensure water flow rate.

[0045] Specifically, Figure 3 In the middle, the scraper 51 has an opening at its lower end, and a baffle 54 is rotatably installed inside the opening; a pin 55 is inserted through the lower end of the scraper 51, and the outer surface of the pin 55 is welded to one side of the baffle 54.

[0046] The pin 55 provides a pivot point for the baffle 54 to rotate, enabling the controllable switching between closed collection and fixed-point discharge of the scraper 51, and preventing debris from falling off midway.

[0047] Specifically, Figure 4 In the middle, a sewage outlet 6 is opened on the inner wall of the gate frame 1 at the lower end of the scraper 51, and a slope 7 is provided on the bottom wall of the sewage outlet 6.

[0048] The sewage outlet 6 connects to the scraper 51 to remove debris, and the ramp 7 accelerates the discharge of debris, avoids siltation, and reduces operation and maintenance costs.

[0049] Working principle: When the drive unit 4 is started, the servo motor 41 drives the drum 42 to rotate. The drum 42 releases the wire rope 43, and the gate body 2 descends along the sliding groove on the inner wall of the gate frame 1 to block water. The grid 3 intercepts debris in the water flow.

[0050] When the screen 3 needs to be cleaned, the servo motor 41 rotates in the opposite direction to drive the drum 42 to wind up the wire rope 43, the gate body 2 rises along the slide groove, and simultaneously drives the scraper 51 to rise. The rear side of the scraper 51 and the comb teeth 53 are in contact with the front side of the screen 3 to scrape and scrape the residual debris on one side of the screen 3 into the scraper 51.

[0051] When the scraper 51 rises to its lower end and is opposite to the drain outlet 6 on the inner wall of the gate frame 1, the baffle 54 at the lower end of the scraper 51 rotates and opens around the pin 55 under its own weight and the pressure of the internal debris. The debris and silt in the scraper 51 fall into the drain outlet 6 through the opening and are discharged along the slope 7 at the bottom of the drain outlet 6.

[0052] After cleaning is completed, if the servo motor 41 is operated to reverse the drum 42, the gate body 2 will fall back to its original position and the gate body 2 needs to be closed. If it is necessary to keep the gate open, the drive unit 4 is controlled to keep the gate body 2 at the specified height.

[0053] 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.
