[0002] In sewage treatment, a grating plate is usually used to intercept sundries in sewage, thereby achieving the effect of filtering large-particle sundries in sewage. When the grating plate is damaged after long-time use, it needs to be replaced to ensure normal use.

[0003] According to the search, the grating mechanism for sewage treatment equipment convenient to replace (CN217119491 U) uses a drive motor to drive a screw to rotate, and then a brush rod can be driven by a nut seat to clean the grating plate up and down, so as to reduce the sundries on the grating plate and reduce the weight of the grating plate. Then, the brush rod is lowered to the bottom of the water inlet frame, the support plate is extended to the bottom of the grating plate under the elastic action of the support rod, and finally the brush rod is lifted by the screw, the grating plate is lifted by the support plate, and the grating plate is taken out more time-saving and labor-saving. The problem of heavy grating plate and strong adhesion is avoided.

[0004] The above application completes the interception of sundries in sewage by a single grating plate. Although the single grating plate can be taken out, the single grating plate needs to be replaced as a whole after being taken out, which is inconvenient and has high maintenance cost.

[0005] Therefore, the utility model designs a grating assembly for sewage treatment convenient to replace to solve the above problems. UTILITY MODEL CONTENTS
