[0026] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0027] Example 1:

[0028] Figure 1-4 and Figure 6-9 The invention shows a freshwater corrosion protection device for a dam ship lock fire monitor, comprising a base 1, a fixed groove 2 is provided on the upper end of the base 1, a circular groove 3 is provided on the inner bottom wall of the fixed groove 2, a fire monitor body 4 is movably inserted into the circular groove 3, a pair of reinforcement grooves 22 are provided on the outer end of the fire monitor body 4, a pair of fixed blocks 5 are fixedly connected to the inner bottom wall of the fixed groove 2, and an electric push rod 6 is fixedly connected to one end of the pair of fixed blocks 5 close to each other. A person skilled in the art can make the best choice of the model of the electric push rod 6, such as ETS-10. A reinforcement block 7 movably inserted into the reinforcement groove 22 is fixedly connected to the telescopic end of the electric push rod 6. The internal rotation of the fixed groove 2 A first protective cover 8 and a second protective cover 9 are connected, the side ends and the lower end of the first protective cover 8 are coated with a first magnetic coating 10, and the side ends and the lower end of the second protective cover 9 are coated with a second magnetic coating 11. A pair of plug-in rods 12 are fixedly connected to the inner wall of the fixed groove 2, and the plug-in rods 12 move from the outside to the inside and penetrate the first protective cover 8 and the second protective cover 9. A sealing groove is provided on the inner wall of the circular groove 3, and a sealing ring 13 is fixedly connected to the inside of the sealing groove. The sealing ring 13 can prevent external fresh water from entering the circular groove 3. The inner wall of the sealing ring 13 is in close contact with the outer end of the fire monitor body 4, and the upper end of the sealing ring 13 is flush with the inner bottom wall of the fixed groove 2.

[0029] Combine Figure 6 As shown, when in use, the lower end of the fire monitor body 4 is inserted into the circular groove 3, the electric push rod 6 is started, and the reinforcing block 7 is pushed into the reinforcing groove 22 by the electric push rod 6. The fire monitor body 4 is limited by the reinforcing block 7, and then the fire monitor body 4 is installed and fixed on the base 1. Then, the first protective cover 8 and the second protective cover 9 are rotated so that the first magnetic coating 10 on the side end of the first protective cover 8 and the second magnetic coating 11 on the side end of the second protective cover 9 are adsorbed together, and then the fire monitor body 4 is covered by the first protective cover 8 and the second protective cover 9, and then the fire monitor body 4 is protected to reduce damage to the surface of the fire monitor body 4 caused by fresh water adhering to the fire monitor body 4;

[0030] When a fire occurs, the fire monitor body 4 is started and its upper end will spray water upwards. The inner top walls of the first protective cover 8 and the second protective cover 9 are both provided with grooves. Figure 9 As shown, when water is sprayed upward, the water flows into the two grooves and exerts a force on the inner walls of the two grooves to move them in different directions, so that the side ends of the first protective cover 8 and the second protective cover 9 move in different directions, thereby opening a certain size of the connection between the side ends of the first protective cover 8 and the second protective cover 9. At the same time, the first protective cover 8 and the second protective cover 9 will rotate on the plug-in rod 12. Due to the magnetic attraction, the first magnetic coating 10 at the lower end of the first protective cover 8 will be adsorbed together with the second magnetic coating 11 at the lower end of the second protective cover 9, thereby maintaining a fixed size of the opening between the side ends of the first protective cover 8 and the second protective cover 9, see Figure 7 As shown, when a fire occurs, personnel can quickly use the fire monitor body 4 to spray water to extinguish the fire.

[0031] Example 2:

[0032] Based on the first embodiment, this embodiment adds structures such as a plug-in block 17 and a sealing plug 18, and the rest of the structure remains the same as the first embodiment.

[0033] Figure 4-5 It is shown that a first water outlet 14 is provided on the inner bottom wall of the fixed groove 2, an arc-shaped groove 15 is provided on the outer end of the base 1, and a second water outlet 16 is provided on the inner wall of the arc-shaped groove 15. The first water outlet 14 is connected to the second water outlet 16, and a plug-in block 17 is movably inserted into the interior of the arc-shaped groove 15. The plug-in block 17 is fixedly connected to a sealing plug 18 at one end close to the base 1. A first frame groove is provided on the inner wall of the arc-shaped groove 15, and a first magnetic frame 21 is fixedly connected to the interior of the first frame groove. A second frame groove is provided at the outer end of the plug-in block 17, and a second magnetic frame 19 is fixedly connected to the interior of the second frame groove. The outer end of the sealing plug 18 is tightly fitted with the inner wall of the second water outlet 16, and the plug-in block 17 is fixedly connected to the end away from the base 1 with a pull-out block 20.

[0034] The specific working process and principle of this utility model:

[0035] When the fire monitor body 4 is started and the connection between the side ends of the first protective cover 8 and the second protective cover 9 is flushed open by water flow, a certain amount of water will fall into the fixed groove 2. Then the pull-out block 20 needs to be pulled manually to pull the plug-in block 17 and the sealing plug 18 out of the arc groove 15 and the second water outlet hole 16 respectively. At the same time, the first magnetic frame 21 will be separated from the second magnetic frame 19. The water falling into the fixed groove 2 will enter the second water outlet hole 16 through the first water outlet hole 14, and finally flow to the outside of the base 1 through the second water outlet hole 16, thereby preventing water from accumulating in the fixed groove 2.
