A return groove is provided on the top of the base, and the square frame is inserted into the inside of the return groove. Two limiting openings are provided on both sides of the base, and a U-shaped plate is movably connected in the limiting opening. A connecting rod is fixedly connected between two adjacent U-shaped plates. Two slots and a socket connected to the return groove are respectively provided on both sides of the base, and one end of the U-shaped plate passes through the socket, the bayonet and the slot in sequence. Slide grooves are provided on both sides of the base, and a card plate is movably connected in the slide groove. A first card slot is provided at the bottom of the card plate, and the first card slot is carded to the connecting rod.

[0007] As a further solution of the present invention, two limiting grooves are provided on one side of the base.

[0008] As a further solution of the present invention, two guide rods are fixedly connected to one side of the connecting rod, and the guide rods are slidably connected to the limiting grooves.

[0009] As a further solution of the present invention, a spring is sleeved on the outer side of the guide rod, and both ends of the spring are fixed to the connecting rod and the base respectively.

[0010] As a further solution of the present invention, two sliding rods are fixed in the sliding groove by bolts, and the sliding rods are slidably connected to the clamping plate.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the present invention.

[0025] Reference Figures 1-6 A protective device for a generator set includes a base 1 and a protective frame 2. A square frame 3 is fixed to the bottom of the protective frame 2 by bolts. Two bayonet holes 4 are provided on both sides of the square frame 3. A return groove 5 is provided on the top of the base 1, and the square frame 3 is inserted into the return groove 5. The protective frame 2 is moved to the top of the base 1 so that the square frame 3 is inserted into the return groove 5 on the base 1. Two limiting openings 11 are provided on both sides of the base 1. A U-shaped plate 8 is slidably connected in the limiting opening 11. A connecting rod 6 is fixed between two adjacent U-shaped plates 8 by bolts. Two slots 13 and a socket 12 connected to the return groove 5 are provided on both sides of the base 1. One end of the U-shaped plate 8 passes through the socket 12, the bayonet 4 and the slot 13 in sequence, and the connecting rod 6 is pulled to move the U-shaped plate 8 along the limit opening 11 until one end of the U-shaped plate 8 is inserted into the slot 13 from the socket 12 and the bayonet 4 in sequence, thereby limiting and fixing the position of the frame 3. Slide grooves 14 are provided on both sides of the base 1, and a card plate 16 is slidably connected in the slide groove 14. A first card slot 17 is provided at the bottom of the card plate 16, and the first card slot 17 is engaged with the connecting rod 6. Push the card plate 16 downward to move it downward along the slide groove 14 until the connecting rod 6 is stuck in the first card slot 17, thereby further fixing the position of the U-shaped plate 8.

[0026] In the present invention, it should be noted that two limiting grooves 7 are provided on one side of the base 1, and two guide rods 9 are fixed to one side of the connecting rod 6 by bolts, and the guide rod 9 is slidably connected to the limiting groove 7. The guide rod 9 can guide the connecting rod 6 so that it can move stably to prevent the connecting rod 6 from being skewed during movement. A spring 10 is sleeved on the outer side of the guide rod 9, and the two ends of the spring 10 are respectively fixed to the connecting rod 6 and the base 1, so that the connecting rod 6 can be automatically reset. Two sliding rods 15 are fixed in the slide groove 14 by bolts, and the sliding rod 15 is slidably connected to the card plate 16. The sliding rod 15 can guide the card plate 16 so that it can move up and down stably. A second slot 18 is provided at the bottom of the card plate 16, and the second slot 18 can be engaged with the connecting rod 6. When the U-shaped plate 8 moves out of the bayonet 4, the connecting rod 6 corresponds to the position of the second slot 18, pushing the card plate 16 to move downward, so that the connecting rod 6 is engaged with the second slot 18. The limiting opening 11 is located at the bottom of the return groove 5.

[0027] Working principle: When it is necessary to protect the generator set installed on the base 1, first move the protection frame 2 to the top of the base 1, insert the square frame 3 into the return groove 5 on the base 1, and then pull the connecting rod 6 to move the U-shaped plate 8 along the limit opening 11 until one end of the U-shaped plate 8 is inserted into the slot 13 from the socket 12 and the bayonet 4 in turn, thereby limiting and fixing the position of the square frame 3, and then push the card plate 16 downward to move it downward along the slide groove 14 until the connecting rod 6 is stuck in the first card slot 17, thereby further fixing the position of the U-shaped plate 8.

[0028] Furthermore, the terms "installed," "disposed," "connected," and "socketed" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.
