[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of this application, a debris barrier screen is disclosed, comprising: a screen body 1; a first support member 21, fixedly disposed on the backwater side of the screen body 1 parallel to the width direction of the channel; a second support member 22, detachably disposed on the screen body 1 parallel to the first support member 21; and positioning components disposed at both ends of the second support member 22. The components include: a telescopic member 31, slidably sleeved within the second support member 22 parallel to it; a mounting plate 32, fixedly disposed at one end of the telescopic member 31 for connection and installation with the channel; a positioning screw 33, one end of which contacts the mounting plate 32; a positioning component 34, fixedly disposed on the second support member 22 for the other end of the positioning screw 33 to pass through; and positioning nuts 35, which can be threadedly connected to the screw and are located on both sides of the positioning component 34.

[0026] In practical use, by setting the first support component 21 on the back side of the bar screen body 1, the bar screen body 1's ability to resist water flow impact can be improved, the risk of deformation of the bar screen body 1 can be reduced, and the bar screen body 1's ability to resist deformation can be improved, thus achieving the best pollution blocking effect.

[0027] During installation, by sliding the telescopic components 31 at both ends of the second support component 22, the mounting plate 32 can be moved to slide along the width direction of the grille body 1 until the mounting plate 32 abuts against the walls on both sides of the channel. Then, the positioning nuts 35 are turned to move the positioning nuts 35 toward the positioning component 34 until the two positioning nuts 35 on both sides of the positioning component 34 clamp the positioning component 34, restricting the telescopic components 31 from sliding along the width direction of the grille body 1, thus completing the support and positioning of the grille body 1 in the width direction of the channel.

[0028] By setting a positioning component, before the grille body 1 is installed into the channel, the telescopic component 31 is retracted into the second support component 22. The overall width of the grille body 1 is smaller than the width of the channel, which facilitates the grille being hoisted into the channel. After the grille body 1 is installed into the channel, the telescopic component 31 can extend out of the second support component 22, and the mounting plate 32 can support the wall of the channel, supporting and positioning the grille body 1 along the width direction, eliminating the installation error of the grille body 1, and improving the installation accuracy of the grille body 1.

[0029] It is worth mentioning that one end of the positioning screw 33 can be fixedly connected to the mounting plate 32 by welding; or it can be directly pressed against the mounting plate 32 without welding.

[0030] It is worth mentioning that several oblong holes are provided on the mounting plate 32, and expansion bolts are passed through the oblong holes to install the mounting plate 32 onto the wall of the channel.

[0031] Reference Figure 4 As shown, the second support component 22 is also installed on the back side of the bar screen body 1, which further enhances the bar screen body 1's resistance to water flow impact, resulting in a stable structure, good reliability, and strong resistance to deformation.

[0032] In this embodiment, when the flow rate of the bar screen body 1 is ≥15m³ 3 At a flow rate of / min / ㎡, the minimum bearing pressure of the grating body 1 is ≥150kpa; the flow rate is large and the interception effect is good.

[0033] Specifically, the positioning assembly also includes two positioning components 34 arranged in parallel, with positioning nuts 35 on both sides of each positioning component 34; this effectively ensures that the positioning nuts 35 limit the telescopic component 31; of course, the number of positioning components 34 can be flexibly changed according to actual installation requirements.

The grille bar 11 and the first mounting plate 41 are connected and installed by the triangular support block 43, which further improves the support stability of the grille body 1.

[0039] Reference Figure 5 As shown, in some embodiments, one or more layers of grid bodies 1 are provided in the channel along the length direction of the grid body 1. On the second support member 22 installed between the two layers of grid bodies 1, support blocks 43 on the upper and lower sides of the first mounting plate 41 are respectively provided for the grid bars 11 of the two layers of grid bodies 1.

[0040] It is worth mentioning that two first mounting plates 41 are installed on the second support component 22 between the two grid bodies 1. The two first mounting plates 41 are connected by bolts, and the two grid bodies 1 are connected to the upper and lower sides of the two first mounting plates 41 by support blocks 43 respectively. Through this design, the second support component 22 can connect the two different grid bodies 1 and provide support for the different grid bodies 1 on both sides, further improving the stability of the grid bodies 1.

[0041] Of course, the number of layers of the grille body 1 can be flexibly increased or decreased depending on the actual installation requirements.

[0042] It is worth mentioning that the first mounting plate 41 and the second mounting plate 42 can be connected by bolts, and the two first mounting plates 41 can also be connected by bolts. The support block 43 can be installed on the grid bar 11 and the first mounting plate 41 by welding.

[0043] Preferably, the first support member 21 is disposed in the middle of the grille body 1 along the length direction of the grille body 1.

[0044] Specifically, the grid also includes: a fixing block 5, which is located at the bottom of the channel and on the back side of the grid body 1, for abutting against the grid body 1; and a second support member 22, which is located at the end of the grid body 1 away from the fixing block 5.

[0045] During installation, embedded parts are installed in the wall of the channel using concrete, and the fixing block 5 can be installed on the embedded parts using bolts.

[0046] Specifically, the grid body 1 is set in the channel at an angle of 75° to 85° to facilitate guiding the grab bucket to slide along the grid body 1.

[0047] Preferably, a groove 6 can be added parallel to the grid body 1 on the wall of the channel to guide the grab bucket to slide and improve the accuracy of the grab bucket entering the grid.

[0048] It is worth mentioning that the slide 6, grid 11, first support component 21, second support component 22, telescopic component 31, mounting plate 32, positioning component 34, first mounting plate 41, second mounting plate 42, support block 43 and fixing block 5 can all be made of 304 stainless steel, which improves the overall corrosion resistance and the service life can reach more than 25 years.
