Technical Field
[0001] This utility model relates to the field of inlet grille technology, specifically an adjustable self-cleaning inlet grille device. Background Technology
[0002] An inlet screen is a filtration device installed before the water inlet in wastewater treatment or water conservancy projects. It is primarily used to intercept solid impurities in the water flow. It consists of a set of parallel metal bars or plates, installed at an angle before the inlet of the water intake channel, pump station collection tank, or water conservancy project. It intercepts suspended solids (such as branches, plastics, fibers, etc.) through the gaps between the bars, preventing blockage of downstream equipment.
[0003] The utility model with announcement number CN217391737U discloses a water inlet treatment bar device for a waterworks. The electric push rod can continuously push and pull the transverse plate, which can repeatedly move on the front of the inner bar. The hard brush connected to the transverse plate can continuously brush the surface of the inner bar, preventing large impurities from clogging the holes of the inner bar and causing bar blockage. It is automatic, convenient to use, and improves work efficiency.
[0004] However, the aforementioned inlet screens still have the following problems in actual use: the drive and adjustment components equipped with the screen are used to separate and clean the incoming water and debris, but the drive and adjustment components equipped with this type of screen are larger in size than existing screens. The drive component protrudes from the side of the screen, so additional space needs to be reserved during installation. At the same time, the drive component is easily affected by sewage impact and pollution due to long-term contact with sewage, requiring continuous maintenance and affecting its service life.
[0005] Therefore, we proposed an adjustable self-cleaning inlet grille device to solve the problems mentioned above. Utility Model Content
[0006] The purpose of this utility model is to provide an adjustable self-cleaning inlet bar screen device to solve the problem that the existing bar screens are equipped with drive components and adjustment components to separate and clean inlet water and dirt. However, the drive components and adjustment components of this type of bar screen are larger in size than existing bar screens, and the drive components protrude from the side of the bar screen. Therefore, additional space needs to be reserved during installation. At the same time, the drive components are easily affected by sewage impact and pollution due to long-term contact with sewage, requiring continuous maintenance and affecting service life.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable self-cleaning inlet grille device, including a grille frame and a positioning liner fixedly installed on the upper part of the outer wall of the grille frame; further comprising:
[0008] The grid frame is provided with an adjustment mechanism, and the adjustment mechanism includes a grid body. The grid body is rotatably mounted inside the grid frame through bearings, and the spacing is adjusted by rotation.
[0009] A cleaning mechanism is provided inside the lower part of the grid frame, and the cleaning mechanism includes a filter screen, with discharge grooves opened on both the left and right sides of the filter screen.
[0010] Preferably, the adjusting mechanism includes an adjusting gear, which is fixedly installed on the right end of the grid body that is equidistantly arranged, and the adjusting gear is rotatably disposed on the outside right side of the grid frame.
[0011] Preferably, the adjustment mechanism includes a guide slide rod, which is lockably installed on the lower right side of the grid frame, and an adjustment lever is fixedly provided at the front end of the guide slide rod, with the upper end of the adjustment lever slidingly extending through the outer surface of the top surface of the grid frame.
[0012] Preferably, the adjustment mechanism includes an adjustment gear set, which is fixedly installed at equal intervals on the top surface of the guide slide rod. The equal-distance adjustment gear set meshes with the adjustment gear, and the water inflow is adjusted by sliding and driving the screen body to rotate.
[0013] Preferably, the cleaning mechanism includes a filter screen that is fixedly installed inside the lower part of the grid frame, and the filter screen filters and removes impurities from the water flowing into the grid frame, thereby achieving both water flow regulation and impurity separation of the incoming water.
[0014] Preferably, the cleaning mechanism includes a collection box, which is detachably installed on the left and right sides of the bottom surface of the grid frame. The upper openings of the collection boxes on the left and right sides correspond to the lower part of the cross groove for removing impurities inside the filter screen, so as to collect and store the impurities after filtration and separation.
[0015] Preferably, the cleaning mechanism includes a cleaning brush plate, which is slidably disposed inside the grid frame and slides against the top surface of the filter screen. The operating handle at the outer end of the cleaning brush plate extends through the outside of the grid frame, and when sliding, it drives the dirt on the top surface of the filter screen to enter the collection box through the discharge groove.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The adjustable self-cleaning water inlet grille device has a grille body installed via a positioning liner. The grille bodies, arranged at equal intervals, rotate to adjust the spacing of the water inlet. The incoming water is separated and filtered through a filter screen below. After being conveyed by a cleaning brush plate, the water is stored in a collection box, preventing clogging of the filter screen and ensuring proper water intake. The specific details are as follows:
[0017] 1. The bar grid frame is installed by contacting the side of the inlet with the positioning liner on the upper outer side, so that the bar grid body filters the incoming water through the bar grid bodies set at equal intervals inside, and at the same time regulates the amount of incoming water.
[0018] Furthermore, the adjusting lever inside the sliding bar body drives the guide slide rod, and the adjusting gear group on its top surface drives the meshing adjusting gear to rotate with the bar body, so as to drive the bar bodies set at equal distances to rotate, thereby adjusting the spacing between adjacent bar bodies and adjusting the influent flow.
[0019] 2. The filter screen below the grid frame filters the water flow, separating mixed dirt and particulate matter. The water continues to flow and is collected, while the dirt is separated on the top surface of the filter screen, preventing it from causing pollution to the incoming water.
[0020] Furthermore, the cleaning brush plate inside the sliding grid frame is designed to fit against the top surface of the filter screen to remove dirt and debris. The horizontal grooves on the left and right sides of the filter screen also remove dirt and debris, which is then stored in the collection box to prevent clogging of the filter screen and disruption of water intake.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-8 The present invention provides the following technical solution:
[0032] Example 1: To address the problems existing in the use of existing inlet grilles, this example discloses the following technical solution: an adjustable self-cleaning inlet grille device, including a grille frame 1 and a positioning liner 2 fixedly installed on the upper outer wall of the grille frame 1; the grille frame 1 is provided with an adjustment mechanism, and the adjustment mechanism includes a grille body 3, which is rotatably installed inside the grille frame 1 via bearings, and the spacing is adjusted by rotation; the adjustment mechanism includes an adjustment gear 6, which is fixedly installed on the right end of the grille body 3, which is rotatably located on the outside right side of the grille frame 1.
[0033] The adjustment mechanism includes a guide slide rod 7, which is lockably installed on the lower right side of the grid frame 1. An adjustment lever 8 is fixedly installed at the front end of the guide slide rod 7, and the upper end of the adjustment lever 8 slides through the outside of the top surface of the grid frame 1. The adjustment mechanism includes an adjustment gear set 9, which is fixedly installed at equal intervals on the top surface of the guide slide rod 7. The equal-interval adjustment gear set 9 meshes with the adjustment gear 6, and the water inflow is adjusted by sliding and driving the grid body 3 to rotate.
[0034] like Figures 4-5 , Figure 8 As shown, when the bar grid frame 1 is installed above the water inlet, the positioning liner 2 on the upper part of the bar grid frame 1 is attached to the side of the water inlet, thereby installing the bar grid frame 1 in contact with the water. The water is filtered by the bar grid bodies 3 arranged at equal intervals inside the bar grid frame 1, and the water inlet volume is adjusted at the same time.
[0035] Furthermore, when adjusting the spacing of the bar screen body 3, the adjusting lever 8 inside the bar screen frame 1 is manually slid backward, causing the guide slide rod 7 fixedly connected at the bottom to slide inside the bar screen frame 1. At the same time, the guide slide rod 7 drives the fixedly installed adjusting gear 9 to mesh with the adjusting gear 6, so that the adjusting gear 6 drives the fixedly connected bar screen body 3 to rotate, so that the adjacent spacing of the plate-shaped bar screen body 3 changes after rotation, thereby adjusting the water inflow.
[0036] Example 2: In order to solve the problems existing in the use of the existing inlet grille, this example discloses the following technical solution: a cleaning mechanism is provided inside the lower part of the grille frame 1, and the cleaning mechanism includes a filter screen 4, and the filter screen 4 has a cross groove 5 for removing impurities on both the left and right sides inside the filter screen 4; the filter screen 4 included in the cleaning mechanism is fixedly installed inside the lower part of the grille frame 1, and the filter screen 4 filters and removes impurities from the water flowing into the grille frame 1, thereby realizing the adjustment of the water inflow and the removal and separation of impurities from the water inflow.
[0037] The cleaning mechanism includes a collection box 10, which is detachably installed on the left and right sides of the bottom surface of the grid frame 1. The upper openings of the collection boxes 10 on the left and right sides correspond to the lower part of the discharge groove 5 opened inside the filter screen 4, so as to collect and store the impurities after filtration and separation. The cleaning mechanism includes a cleaning brush 11, which is slidably disposed inside the grid frame 1 and slides against the top surface of the filter screen 4. The operating handle at the outer end of the cleaning brush 11 extends through the outside of the grid frame 1. When sliding, it drives the impurities on the top surface of the filter screen 4 to enter the collection box 10 through the discharge groove 5.
[0038] like Figure 2 , Figures 6-7 As shown, after the water flows into the interior of the grid frame 1, the filter screen 4 installed at the bottom of the interior of the grid frame 1 filters the water flow to separate the mixed dirt and particulate matter. The water flow continues to flow for collection, and then the dirt is separated on the top surface of the filter screen 4 to prevent it from causing pollution to the incoming water.
[0039] Furthermore, impurities are separated and filtered by the filter screen 4 and stored on the top surface of the filter screen 4. Then, the cleaning brush plate 11 that runs through the inside of the grid frame 1 is manually slid along one of the long sides of the grid frame 1 to fit against the top surface of the filter screen 4 and remove the impurities. Then, the impurities are cleared by the discharge grooves 5 opened on the left and right sides of the filter screen 4 so that they can enter the internal storage of the collection box 10 and avoid clogging the filter screen 4 and affecting the water intake operation.
[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
