DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] REFERENCE Figures 1-4, a high-risk operation indicating device for a thermal power plant, including a protective box 1. An indicator light 2 is installed on the top surface of the protective box 1. A revolving door 3 is rotatably connected to the outside of the protective box 1 through a rotating shaft 12. Signboards 5 are fixedly installed on the outer side of the revolving door 3 and the side wall of the protective box 1 respectively. Elastic boxes 8 are fixedly installed on both inner walls of the protective box 1. An assembly seat 19 is elastically slidably connected in each elastic box 8. A hook 17 is fixedly installed on the bottom surface of each assembly seat 19, and each hook 17 penetrates through the elastic box 8. A hidden seat 21 is fixedly installed on the bottom surface of each elastic box 8. Grooves 7 are opened in both side frames of the protective box 1. A pin 22 is slidably connected up and down in each groove 7. A plurality of card slots 14 are opened on the outer sides of both ends of the rotating shaft 12. Through grooves 9 are opened on both side walls of the protective box 1, and the through grooves 9 are communicated with the grooves 7. Each elastic box 8 drives the pin 22 to slide and the assembly seat 19 to slide in the opposite direction through a connection mechanism.

[0024] As Figures 1-4 shown, the implementation method is specifically as follows: By setting the signboard 5, workers can see the signboard 5 both before and after opening the revolving door 3, so as to play a warning role for workers. At the same time, through the assembly seat 19, the hook 17, the safety belt can be hung on the hook 17 and the assembly seat 19 is driven to slide downward. The pin 22 and the card slot 14 are set. The pin 22 can be inserted into the card slot 14, so that the rotating shaft 12 is fixed and the revolving door 3 cannot rotate. Through the connection mechanism, the assembly seat 19 and the pin 22 move in the opposite direction. When the assembly seat 19 slides downward, the pin 22 is lifted upward.

[0025] Each connection mechanism includes a second rack 16, and the side surface of the second rack 16 passes through the through groove 9 and is fixedly connected to the corresponding assembly seat 19. A gear 15 is rotatably connected in each groove 7. A first rack 11 is slidably connected in each groove 7. Each second rack 16 and each first rack 11 are meshed with the corresponding gear 15, and each pin 22 is fixedly installed at the bottom end of the corresponding first rack 11.

[0026] When the assembly seat 19 slides downward, the second rack 16 is driven to slide, so that the gear 15 rotates, driving the first rack 11 to lift upward, and further lifting the pin 22.

[0027] A slider 13 is fixedly installed on the outer side of each first rack 11. Slide grooves 10 are opened on both side walls of each groove 7, and each slider 13 is slidably connected in the corresponding slide groove 10.

[0028] Through the setting of the slide groove 10 and the slider 13, the sliding of the first rack 11 is more stable.

[0029] The top surface of each assembling seat 19 is fixedly installed with a spring 20, and the top end of each spring 20 is fixedly connected with the top wall of the elastic box 8.

[0030] The assembling seat 19 can be driven upward by the spring 20.

[0031] Each hook 17 is L-shaped, and the bottom end of each hook 17 is movably connected with a pull ring 18.

[0032] The hook 17 can be pulled out when the hook 17 is hidden through the pull ring 18.

[0033] The top wall of the protection box 1 is fixedly installed with a fan 6, and the outer side of the rotating door 3 is fixedly installed with a handle 4.

[0034] The safety belt in the protection box 1 can be blown by the fan 6, so that the drying of the safety belt is accelerated, and the safety factor of the safety belt caused by moisture is avoided.

[0035] When the utility model is used, first, the rotating door 3 is opened through the handle 4, at this time, the rotating door 3 is separated from the protection box 1, so that the indicator light 2 emits light to make warning, then the safety belt hung on the hook 17 is taken out, the safety belt can be used, and when the safety belt is in the protection box 1, the protection box 1 can be blown by the fan 6, so that the drying of the safety belt is accelerated, thereby prolonging the service life of the safety belt;

[0036] When the safety belt is taken out, the assembling seat 19 is lifted upward under the action force of the spring 20, and the convex part of the hook 17 is hidden in the hidden seat 21, when the assembling seat 19 slides upward, the second rack 16 is driven to slide upward, so that the first rack 11 slides downward under the action of the gear 15, and then the pin 22 is inserted into the clamping groove 14 formed in the rotating shaft 12, so that the rotating door 3 cannot rotate at this time.

[0037] When the safety belt is used up, the hidden hook 17 is pulled out through the pull ring 18, the assembling seat 19 slides downward, so that the pin 22 is separated from the clamping groove 14 under the action of the gear 15 and the second rack 16, thereby limiting the rotating door 3, then the safety belt is hung again, the assembling seat 19 is kept in this position through the gravity of the safety belt, and then the rotating door 3 can be closed again through the handle 4, at this time, the indicator light 2 stops flashing, when the safety belt is placed randomly by the worker, the rotating door 3 cannot be closed, and the indicator light 2 is always in the flashing state to give a warning and indication to the worker.

[0038] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
