Description

Technical Field

[0001] This utility model belongs to the field of water conservancy facilities technology, and specifically relates to a water conservancy grid. Background Technology

[0002] Hydraulic screens are a type of equipment mainly used for cleaning and trapping debris in water treatment processes. They are widely used in drainage pumping stations, river channels, and the inlets of large hydraulic pumping stations to intercept solid floating debris in water bodies, ensuring smooth water flow. As a pretreatment facility, screens play an irreplaceable role in wastewater treatment processes, preventing floating objects from entering subsequent treatment stages.

[0003] After a period of use, some existing hydraulic screens require manual removal of floating debris that is blocked on one side of the screen. During the collection and removal process, some smaller floating debris is easily leaked out of the gaps in the screen due to accidental contact by workers or the impact of waves generated during the operation. This debris then floats into the water behind the screen, which has a relatively adverse effect on the subsequent treatment of the water. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a hydraulic screen to solve the problem mentioned in the background art that after a period of use, some existing hydraulic screens require manual cleaning of floating objects blocked on one side of the screen. During the collection and cleaning process, some smaller floating objects are easily leaked out of the gaps in the screen due to accidental contact by the operators or the impact of waves generated during the operation, and thus float to the water behind, which has a relatively adverse effect on the subsequent treatment of the water.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic grid, comprising a main body and a blocking mechanism disposed on one side of the main body, the blocking mechanism comprising a slide rail fixedly connected to one side of the frame and symmetrically arranged thereon, a slider slidably connected to the inner side of the slide rail, a main frame fixedly connected to one side of the slider, a retention net fixedly connected to the inner side of the main frame, a locking screw threadedly connected to the inner side of the main frame, a pressure ring fixedly connected to the outer side of one end of the locking screw, and a slide rail slidably connected to the outer side of the locking screw.

[0006] Preferably, a mounting foot pad is fixedly connected to one side of the frame, and several mounting foot pads are symmetrically arranged. Each mounting foot pad has a screw hole on its inner side. A horizontal partition is fixedly connected to the inner side of the frame, and several horizontal partitions are symmetrically arranged. Several vertical partitions are symmetrically arranged on the outer side of the horizontal partitions. A frame is fixedly connected to one side of each vertical partition.

[0007] Preferably, a knob is fixedly connected to one side of the pressure ring, and several knobs are symmetrically arranged. A locking screw is fixedly connected to the inner side of the pressure ring.

[0008] Preferably, a washer is movably connected to the outer side of the other end of the locking screw, and the washer is located between the slide rail and the pressure ring.

[0009] Preferably, a ruler is fixedly connected to one side inside the main frame, and two rulers are symmetrically arranged, with the rulers located on one side of the retention net.

[0010] Preferably, a limiting piece is fixedly connected to the inner side of the top of the slide rail, and the limiting piece is located above the slider.

[0011] Preferably, a handle is fixedly connected to the top of the main frame, and the outer surface of the handle is treated with a deburring process.

[0012] Preferably, all the blocking mechanisms are made of stainless steel.

[0013] Compared with the prior art, the present invention provides a hydraulic grating with the following advantages:

[0014] 1. This utility model uses a retention net to install the main body mechanism in a predetermined position using the screw holes on the inner side of the mounting pad. The vertical and horizontal spacers then act as a barrier, trapping floating debris in the water. After a period of use, when a large amount of floating debris settles between the top of the water surface and the main body mechanism, the pressure ring and its internal locking screw are rotated counterclockwise, depending on the height of the floating debris. This reduces the pressure of the outer wall of the slider against the inner wall of the slide rail, thus releasing the restriction on the slider's position within the slide rail. Then, by holding the handle, the slider is slid vertically until the retention net inside the main frame is aligned with the floating debris on the water surface. At the same height, rotate the locking screw clockwise to increase the pressure of the outer wall of the slider pressing against the inner wall of the slide rail and the pressure of the pressure ring pressing against the outer wall of the slide rail, thereby fixing the retention net at the current height. Finally, start cleaning the floating objects on one side of the frame. During this period, some smaller floating objects may leak out from the gap between the vertical and horizontal partitions due to external forces. They will be blocked by the retention net and thus cannot flow into the water behind the frame. After all the cleaning is completed, reset the main frame and the retention net. This can effectively reduce the occurrence of some small floating objects leaking out from the gaps in the grid and flowing into the water behind the frame during the cleaning process, thus improving the effect of subsequent water treatment processes.

[0015] 2. This utility model, by setting a knob, can effectively and conveniently allow personnel to directly pinch and rotate it without the aid of external tools;

[0016] 3. By setting a shim, this utility model can effectively reduce the loosening range of the locking screw during long-term use, and ensure the stability of the locking screw's positioning ability.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-4This utility model provides a technical solution: a hydraulic grid, including a main body mechanism 1 and a blocking mechanism 2 disposed on one side of the main body mechanism 1. The blocking mechanism 2 includes a slide rail 201 fixedly connected to one side of the frame 101 and symmetrically arranged thereon. A slider 202 is slidably connected to the inner side of the slide rail 201. A main frame 203 is fixedly connected to one side of the slider 202. A retention net 204 is fixedly connected to the inner side of the main frame 203. A locking screw 205 is threadedly connected to the inner side of the main frame 203. A pressure rod is fixedly connected to the outer side of one end of the locking screw 205. Ring 206 and locking screw 205 are slidably connected to slide rail 201. The main body mechanism 1 is installed in the predetermined position by the screw hole provided on the inner side of the mounting foot pad 102. Then, the barrier formed between the vertical spacer 103 and the horizontal spacer 104 obstructs floating objects in the water. After a period of use, when a large amount of floating objects settle between the top of the water surface and the main body mechanism 1, the knob 3 is directly squeezed and rotated counterclockwise to press the ring 206 and the locking screw 205 inside, according to the height position of the floating objects on the water surface. Reduce the pressure of the outer wall of slider 202 against the inner wall of slide rail 201, thereby releasing the restriction on the position of slider 202 within slide rail 201. Then, holding handle 7, slide slider 202 vertically until the retention net 204 inside the main frame 203 is at the same height as the floating objects on the water surface. Rotate locking screw 205 clockwise to increase the pressure of the outer wall of slider 202 against the inner wall of slide rail 201 and the pressure of one side of pressure ring 206 against the outer wall of slide rail 201, thereby fixing retention net 204 at the current height. Finally, begin cleaning the floating debris on one side of the frame 101. During this process, some smaller floating debris may leak out from the gap between the vertical partition 103 and the horizontal partition 104 due to external forces. It will be blocked by the retention net 204 and thus unable to flow into the downstream water body. After all the cleaning is completed, the main frame 203 and the retention net 204 can be reset. This can effectively reduce the occurrence of some small floating debris leaking out from the gaps in the grid and flowing into the downstream water body during the cleaning process, thereby improving the effect of subsequent water treatment processes.

[0026] In this utility model, preferably, a mounting foot pad 102 is fixedly connected to one side of the frame 101, and several mounting foot pads 102 are symmetrically arranged. Each mounting foot pad 102 has a screw hole on its inner side. A horizontal partition 104 is fixedly connected to the inner side of the frame 101, and several horizontal partitions 104 are symmetrically arranged. Several vertical partitions 103 are symmetrically arranged on the outer side of the horizontal partitions 104. The frame 101 is fixedly connected to one side of the vertical partition 103. The main body mechanism 1 is installed in a predetermined position with the screw hole provided on the inner side of the mounting foot pad 102. Then, the obstruction formed between the vertical partitions 103 and the horizontal partitions 104 can block floating objects in the water.

[0027] In this utility model, preferably, a knob 3 is fixedly connected to one side of the pressure ring 206, and several knobs 3 are symmetrically arranged. A locking screw 205 is fixedly connected to the inner side of the pressure ring 206, which can effectively facilitate personnel to directly pinch and rotate without the aid of external tools.

[0028] In this utility model, preferably, a washer 4 is movably connected to the outer side of the other end of the locking screw 205. The washer 4 is located between the slide rail 201 and the pressure ring 206, which can effectively reduce the loosening range of the locking screw 205 during long-term use and ensure the stability of the positioning ability of the locking screw 205.

[0029] In this utility model, preferably, a ruler 5 is fixedly connected to one side of the inside of the main frame 203. Two rulers 5 are symmetrically arranged. The rulers 5 are located on one side of the retention net 204, which can effectively and conveniently allow personnel to adjust the retention net 204 to the position where the liquid level is in the center.

[0030] In this utility model, preferably, a limiting piece 6 is fixedly connected to the inner side of the top of the slide rail 201. The limiting piece 6 is located above the slider 202, which can effectively limit the sliding stroke of the slider 202 and reduce the risk of falling off due to excessive sliding.

[0031] In this utility model, preferably, a handle 7 is fixedly connected to the top of the main frame 203. The outer surface of the handle 7 is treated with a deburring process, which can effectively facilitate the person to hold and slide the main frame 203.

[0032] In this invention, preferably, the blocking mechanism 2 is made of stainless steel, which can effectively reduce the risk of material strength reduction caused by oxidation and corrosion.

[0033] The working principle and usage process of this utility model are as follows: In use, the main body mechanism 1 is installed in the predetermined position using the screw holes provided on the inner side of the mounting foot pad 102. Then, the vertical spacer 103 and the horizontal spacer 104 act as a barrier, impeding floating objects in the water. After a period of use, when a large amount of floating objects accumulate between the top of the water surface and the main body mechanism 1, the knob 3 is directly squeezed and the pressure ring 206 and its internal locking screw 205 are rotated counterclockwise according to the height of the floating objects. This reduces the pressure of the outer wall of the slider 202 pressing against the inner wall of the slide rail 201, thereby releasing the restriction on the position of the slider 202 within the slide rail 201. Then, the handle 7 is held, and the slider 202 is slid vertically to the retention net 204 inside the main frame 203 and the floating objects on the water surface. When the floating objects are at the same height, rotate the locking screw 205 clockwise to increase the pressure of the outer wall of the slider 202 on the inner wall of the slide rail 201 and the pressure of the pressure ring 206 on the outer wall of the slide rail 201. This fixes the retention net 204 at the current height. Finally, start cleaning the floating objects on one side of the frame 101. During this process, some smaller floating objects may leak out from the gap between the vertical partition 103 and the horizontal partition 104 due to external forces. They are blocked by the retention net 204 and cannot flow to the downstream water body. After all the cleaning is completed, the main frame 203 and the retention net 204 can be reset. This can effectively reduce the occurrence of some small floating objects leaking out of the grid gaps and flowing into the downstream water body during the cleaning process, thus improving the effect of subsequent water treatment processes.
