Among the four sides of the lower end surface of the cover body, two opposite side edges are provided with horizontally extending mounting plates, and a reinforcing steel plate is wrapped inside the mounting plates. Reinforcing rods are installed along the side edges of the cone on the inner side wall of the cover body. However, there are still the following defects:
