Well lid for sponge city

Abstract

The invention belongs to the field of sponge city development, and relates to a well lid for a sponge city. The well lid for the sponge city comprises a shell, four self-locking devices are fixedly arranged on the lower side of the shell, an alarm cavity is formed in the lower side of the shell, an alarm device is arranged in the alarm cavity, a water storage cavity is formed in the upper side of the shell, a water storage device is arranged in the water storage cavity, a water spraying cavity is formed in the water storage cavity, and a water spraying device is arranged in the water spraying cavity. According to the well lid, the well lid can be self-locked at a well mouth, so that the well lid is not easy to steal, the irresistible reason of a sewer can be prevented, the concentration of the biogas at the bottom of the well can be detected by generating biogas expansion explosion, and when the concentration of the biogas exceeds the standard, the biogas is treated and discharged in time, so that the concentration of the biogas at the bottom of the well cannot exceed the standard, water can be collected, the water can be efficiently stored, intermittent water spraying and heat dissipation can be realized on the well lid, the water can be prevented from being sucked back due to water spraying, a water pump is protected, and stones and impurities in the water can be prevented from being collected during water spraying.

Description

technical field [0001] The invention belongs to the field of sponge city development, and in particular relates to a manhole cover for a sponge city. Background technique [0002] As we all know, the construction of sponge city can reduce surface runoff, alleviate urban waterlogging, replenish groundwater, restore urban ecological environment, alleviate urban heat island and rain island effect, and build a green, harmonious, ecological and safe urban living environment. Increase urban greening, beautify the urban environment, and improve urban quality. Therefore, the construction of sponge cities is of great significance to future urban development. The construction products of sponge cities have manhole covers for sponge cities. The theft of the manhole cover may also be an irresistible reason for the sewer, resulting in biogas expansion and explosion, so that the manhole cover splashes and hurts pedestrians, cannot detect the concentration of biogas at the bottom of the we...

Increase urban greening, beautify the urban environment, and improve urban quality. Therefore, the construction of sponge cities is of great significance to future urban development. The construction products of sponge cities have manhole covers for sponge cities. The theft of the manhole cover may also be an irresistible reason for the sewer, resulting in biogas expansion and explosion, so that the manhole cover splashes and hurts pedestrians, cannot detect the concentration of biogas at the bottom of the well and the treatment after the concentration of biogas exceeds the standard, cannot collect water and store water efficiently, thereby enhancing water resource utilization
