This invention discloses a deluge valve with an intelligent protection device, relating to the field of deluge valve technology. It includes a valve body, a protrusion, a valve cover mounting portion, a valve cover, a sealing diaphragm, a positioning portion, a mounting base, an elastic drive mechanism, a pressure block, rotating plates, and a compression drive mechanism. The compression drive mechanism drives two rotating plates to flip downwards, causing the lower ends of the rotating plates to respectively compress the surfaces of the sealing diaphragm corresponding to the axial sides of the valve body. By setting the compression drive mechanism, the rotating plates flip downwards, and the lower ends of the two rotating plates respectively compress the sides of the protrusion. Combined with the compression of the sealing diaphragm by the pressure block, when the sealing diaphragm wears down, the rotating plates can compress the sealing diaphragm, reducing or even eliminating the gap between the sealing diaphragm and the protrusion. This prevents water leakage inside the valve body after the sealing diaphragm wears down, and also reduces the impact of fluid on the worn areas of the sealing diaphragm, thereby reducing the degree of wear on the sealing diaphragm.

The utility model discloses a garden construction tree wind-inclination-resistant supporting structure which comprises a plurality of stand columns arranged on the peripheral side of a soil ball at intervals and fixedly inserted into a tree pool. The transverse frame is arranged at the tops of the soil balls and the stand columns and is lower than the top edge of the tree pool, the transverse frame comprises two frames which are oppositely arranged, the two frames are detachably connected, and the two frames are detachably connected with the stand columns; the upper end of the supporting assembly is connected with the trunk of the tree, and the lower end is rotationally connected with the frame; the stone grain layer is laid on the top of the inner cavity of the tree pool. According to the scheme, the stand columns are fixedly inserted into the tree pool, the transverse frames are arranged at the tops of the soil balls, the soil balls can be well positioned, the arranged supporting assemblies can support tree trunks, in this way, trees can be positioned and supported, and the stability of the trees is improved; and the supporting structure cannot intrude into the road surface, so that the influence on the passing of pedestrians is avoided.
