Description

Technical Field

[0001] The utility model relates to the technical field of trash racks, in particular to a trash rack for river sewage treatment. Background Art

[0002] Trash rack is a frame-type structure used to intercept debris carried in water flow. Trash rack is usually composed of frame, diaphragm and bars, generally made of steel and fixed on concrete pier wall. It is mainly set at the entrance of water flow into reservoirs, rivers, lakes or sewage treatment plants and other important water bodies to prevent these debris from entering downstream water treatment facilities or causing damage to the water environment. The design of trash rack needs to take into account the characteristics of the intercepted debris to ensure its effectiveness and protection of the water body.

[0003] Most of the existing trash racks are welded structures, which cannot be flexibly adjusted. As a result, when the trash racks are in use, they cannot effectively adjust their spacing to match the characteristics of the intercepted debris. At the same time, because the trash racks are under the water body for a long time and the blades are accumulated by debris, the welding points of the blades will crack and fall off, which will affect their normal use and reduce their service life.

[0006] A frame, wherein a cross bar is arranged at the center of the frame, positioning grooves are provided on the horizontal ends of the frame and the cross bar, fence blades are inserted into the positioning grooves, pull rods penetrate the positioning grooves and the fence blades, and nuts are threadedly connected at both ends of the pull rods.

[0007] Preferably, the frame is a rectangular structure, and the frame includes two vertical ends and two horizontal ends. The frame and the cross bar are an integrated structure, and the frame and the cross bar are a Japanese-shaped structure.

[0008] Preferably, a mounting hole is formed on an outer wall of the vertical end of the frame, and the width of the mounting hole is greater than the diameter of the nut, and a support plate is fixedly connected to the bottom of the frame.

[0009] Preferably, the interval between adjacent positioning grooves is two centimeters, and the depth of the positioning groove is three-fifths of the thickness of the frame.

[0010] Preferably, a first positioning hole is formed through the center of the positioning groove, a second positioning hole is formed on the grating blade corresponding to the first positioning hole, and a pull rod is formed between the first positioning hole and the second positioning hole.

[0011] Preferably, there are five groups of pull rods in total, and both ends of each group of pull rods are threadedly connected with nuts, two groups of pull rods are passed through the upper and lower ends of the grating blades, and one group of pull rods is passed through the cross bar.

[0012] Preferably, the width of the support plate is equal to the thickness of the frame, and the thickness of the support plate is consistent with the thickness of the grating blades.

[0013] Compared with the prior art, the beneficial effect of the utility model is that the utility model, through the setting of the splicing structure, can effectively realize the flexible adjustment of the position of the grating blades when the device is in use, so that the device can better adapt to the type of intercepted debris to adjust its spacing, greatly improving its adaptability to the place of use, and at the same time adopts plug-in splicing positioning treatment, compared with the traditional welding structure, its service life is more stable, and the grating blades will not crack or fall off even if immersed in the water for a long time, thereby ensuring the high efficiency of the device.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The utility model provides an embodiment: a trash rack for river sewage treatment, comprising:

[0022] A frame 1 is provided with a cross bar 2 at the center of the frame 1, a positioning groove 4 is provided on the horizontal end of the frame 1 and the cross bar 2, a fence leaf 5 is inserted into the positioning groove 4, a pull rod 6 passes through the positioning groove 4 and the fence leaf 5, and nuts 7 are threadedly connected to both ends of the pull rod 6. Through the plug-in connection between the fence leaf 5 and the positioning groove 4, the installation position of the fence leaf 5 can be flexibly adjusted, so that when the device is in use, the spacing between the fence leaves 5 can be flexibly adjusted according to different places of use and different intercepted debris, which greatly improves the adaptability and convenience of the use of the device.

[0023] Furthermore, the frame 1 is a rectangular structure, and the frame 1 includes two vertical ends and two horizontal ends. The frame 1 and the cross bar 2 are an integrated structure, and the frame 1 and the cross bar 2 are a Japanese-shaped structure. The outer wall of the vertical end of the frame 1 is provided with a mounting hole 3, and the width of the mounting hole 3 is greater than the diameter of the nut 7. The bottom of the frame 1 is fixedly connected with a support plate 8. Through the distribution of the support plate 8, the grating blade 5 can be limited and blocked, thereby facilitating the rapid positioning of the grating blade 5 for insertion, and further improving the convenience of its installation.

[0024] Furthermore, the interval between adjacent positioning grooves 4 is two centimeters, and the depth of the positioning groove 4 is three-fifths of the thickness of the frame 1. A first positioning hole is opened through the center of the positioning groove 4, and a second positioning hole is opened on the fence leaf 5 corresponding to the first positioning hole, and a pull rod 6 is passed through the first positioning hole and the second positioning hole. There are five groups of pull rods 6 in total, and both ends of each group of pull rods 6 are threaded with nuts 7. Two groups of pull rods 6 are passed through the upper and lower ends of the fence leaf 5, and a group of pull rods 6 is passed through the cross bar 2. Through the penetration of the pull rods 6 and the locking with the nuts 7, the plug-in positioning of the fence leaf 5 can be completed, thereby ensuring the stability of the plug-in of the fence leaf 5 and avoiding its position movement. At the same time, through its plug-in splicing connection, compared with the traditional welding structure, it effectively avoids the rust and cracking of the fence leaf 5 in the later stage of use, thereby avoiding the falling off of the fence leaf 5, further improving the service life of the device.

[0025] Furthermore, the width of the support plate 8 is equal to the thickness of the frame 1 , and the thickness of the support plate 8 is consistent with the thickness of the grating blade 5 .

[0026] Working principle: The frame 1 and nut 7 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here. When the utility model is used, the device is first installed. First, the spacing of the fence leaves 5 is calculated according to the position and the type of intercepted debris. Further, the fence leaves 5 are plugged in and positioned according to the optimal installation spacing of the fence leaves 5. After plugging, the pull rod 6 is passed through, and the nut 7 is locked. Finally, the locking and positioning of the fence leaves 5 are completed, and the debris can be filtered and intercepted through the device.
