[0023] Figures 1-5A new type of fiberglass arch cover showing an embodiment of the present utility model, which includes a fixed fiberglass arch cover 1 and a plurality of movable fiberglass arch covers 2: The fixed fiberglass arch cover 1 is arranged at the bottommost part, and the plurality of movable fiberglass arch covers 2 are arranged one by one upward. The fixed fiberglass arch cover 1 and the movable fiberglass arch covers 2 are slidably connected, and the adjacent two movable fiberglass arch covers 2 are slidably connected. On the right side of the inner cavity of the fixed fiberglass arch cover 1, a first mounting block 3 is fixedly installed. On the right side of the inner cavity of the movable fiberglass arch cover 2, a second mounting block 4 is fixedly installed. The first mounting block 3 and the second mounting block 4 are connected by a connecting component 5, and the adjacent two second mounting blocks 4 are also connected by the connecting component 5. The adjacent two connecting components 5 are meshed with each other. The connecting component 5 is composed of two gear rod connecting components 51. The two gear rod connecting components 51 are arranged symmetrically front and back. The two gear rod connecting components 51 are meshed with each other. The left and right adjacent gear rod connecting components 51 are meshed with each other. The gear rod connecting component 51 is composed of two single-headed gear rods 511. The two single-headed gear rods 511 are rotatably connected. The opposite sides of the two single-headed gear rods 511 are rotatably connected to the bottom of the first mounting block 3 or the second mounting block 4. The front and back adjacent single-headed gear rods 511 are meshed with each other. The opposite sides of the left and right adjacent single-headed gear rods 511 are meshed with each other. A threaded rod 6 extending to the outside is rotatably connected in the inner cavity of the first mounting block 3. The second mounting block 4 adjacent to the first mounting block 3 is threadedly connected to the surface of the threaded rod 6. A through hole 7 for the threaded rod 6 to move is penetrated through the surface of the second mounting block 4 not adjacent to the first mounting block 3. A motor 8 is fixedly installed on the left side of the first mounting block 3. The output shaft of the motor 8 extends into the inner cavity of the first mounting block 3 and is fixedly connected to the threaded rod 6.
