[0002] A steam boiler is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. Steam boilers are widely used in industrial production, heating, and power generation. They release heat through fuel combustion, heating the water inside the boiler and vaporizing it into steam with a certain pressure and temperature. This steam can then be used as a power source to drive machinery or in processes such as heating and drying. With technological advancements, steam boilers are developing towards higher efficiency, environmental friendliness, and intelligence to meet the needs and environmental requirements of different fields. Some steam boilers are equipped with parameter monitoring equipment, which can monitor relevant internal parameters of the boiler, facilitating the monitoring of its operating status.

[0003] Some existing steam boilers only have water level gauges and lack water level alarm devices. They cannot provide alarm prompts when the water level is too low, which can easily lead to dry burning and cause danger. Utility Model Content

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example

[0023] like Figure 1-6 As shown, the steam boiler parameter control and early warning device proposed in this utility model includes a boiler body 1, which boils water inside the boiler body 1. The bottom of the boiler body 1 is horizontal and the whole is a cuboid structure. When in use, it is placed on a horizontal ground. A control cabinet 101 is installed on the front side of the boiler body 1. The control cabinet 101 contains relevant instruments that display relevant parameters. A steam outlet pipe 102 is fixedly connected to the top of the boiler body 1 for steam to be discharged.

[0024] A mounting plate 2 is fixedly connected to the side of the boiler body 1. The mounting plate 2 is on the right side of the boiler body 1 and is flush with the bottom surface of the boiler body 1. A slide rail 201 is fixedly connected to the top of the mounting plate 2. There are two slide rails 201, which are perpendicular to the mounting plate 2 and parallel to each other. The slide rails 201 are made of hard material and are not easily deformed. A limit block 203 is fixedly connected inside the slide rail 201. A connecting frame 202 is fixedly connected to the side of the boiler body 1. The connecting frame 202 is fixedly connected to the slide rail 201 and connects the boiler body 1 and the slide rail 201, making the slide rail 201 more stable.

[0025] The slide rail 201 is equipped with a first moving block 4 inside. The first moving block 4 can move up and down inside the slide rail 201. The first moving block 4 does not contact the slide rail 201. The middle of the first moving block 4 is rotatably connected to a first roller 402. There are four first rollers 402, which are distributed on the front and rear sides. The first rollers 402 contact the slide rail 201. The first moving block 4 moves up and down, which can make the first rollers 402 rotate. The rotation of the first rollers 402 can reduce the resistance of the first moving block 4 moving up and down, making it easier for the first moving block 4 to move up and down. The slide rail 201 limits the first rollers 402, so that the first moving block 4 can only move up and down and cannot move in other directions. The limiting block 203 limits the first moving block 4.

[0026] A rack 401 is fixedly connected to the side of the first moving block 4. The rack 401 moves up and down with the first moving block 4. A bracket 3 is fixedly connected to the top of the mounting plate 2. The bracket 3 provides support. A gear 301 is rotatably connected to the middle of the bracket 3. The bracket 3 supports the gear 301. The gear 301 can rotate on the bracket 3. The rack 401 meshes with the gear 301. The rack 401 moves up and down, which allows the gear 301 to rotate. The limiting block 203 limits the first moving block 4. When the first moving block 4 moves from the bottom to the top, the gear 301 rotates exactly half a turn.

[0027] A rotating box 302 is fixedly connected to the front side of the gear 301. The rotating box 302 is made entirely of insulating material. The rotating box 302 rotates with the gear 301; a half-turn rotation of the gear 301 causes the rotating box 302 to rotate half a turn. Two metal plates 303 are fixedly installed on the inner wall of the rotating box 302 and are conductive. A metal ball 304 is located inside the rotating box 302 and is also conductive. When the first moving block 4 is on the lower side, the metal ball 304 contacts the two metal plates 303, and the two metal plates 303 are conductive. When the first moving block 4 is on the lower side... After being moved upwards, the metal ball 304 does not contact the two metal plates 303, the two metal plates 303 are not conductive, and wires are led out from the two metal plates 303 and connected to the circuit (not shown in the figure). The current in the circuit is small, and no electric arc will be generated between the metal ball 304 and the metal plates 303. A buzzer 305 is fixedly installed on the front side of the boiler body 1, and a flashlight 306 is fixedly installed on the top of the boiler body 1. The two metal plates 303 are conductive, which can connect the circuit of the buzzer 305 and the flashlight 306. The buzzer 305 emits a sound, and the flashlight 306 emits a flash for reminder.

[0028] The slide rail 201 is equipped with a second moving block 404, which can also move up and down. A screw 403 is rotatably connected to the middle of the first moving block 4. The screw 403 is threadedly connected to the second moving block 404. Rotating the screw 403 can make the second moving block 404 move up and down relative to the first moving block 4. A second roller 405 is rotatably connected to the middle of the second moving block 404. The second roller 405 contacts the slide rail 201. The second roller 405 can make the second moving block 404 move up and down more easily, which is the same as the first moving block 4.

[0029] The second movable block 404 is fixedly connected to the side of the movable frame 406, and the movable ball 407 is fixedly installed at the end of the movable frame 406. The movable ball 407 is hollow inside and is made of metal. However, because it is hollow inside, it is relatively light. Water can make the movable ball 407 float. The movable ball 407 has a large buoyancy and can move the movable frame 406, the second movable block 404, the screw 403 and the first movable block 4 upward. The movable frame 406 is slidably connected to the boiler body 1. The movable frame 406 and the second movable block 404 are a whole and move up and down together in the vertical direction. The boiler body 1 does not affect the up and down movement of the movable frame 406.

[0030] In this embodiment, at the start of use, the boiler body 1 is empty of water, and the first moving block 4 is at the bottom. Adding water causes the moving ball 407 to float. The moving ball 407 has a large buoyancy, which moves the moving frame 406, the second moving block 404, the screw 403, and the first moving block 4 upwards. Continuing to add water, the first moving block 4 contacts the limiting block 203, and the moving ball 407 will no longer float. At this time, the metal ball 304 is not in contact with the two metal plates 303, and the two metal plates 303 are not conductive. During the water addition process, the rotation of the gear 301 can be detected to ensure the stability of the equipment. If the water level drops, the moving... When ball 407 descends, the moving frame 406, the second moving block 404, the screw 403, and the first moving block 4 move downwards, the rack 401 moves downwards, the gear 301 rotates half a turn, and the rotating box 302 rotates half a turn. At this time, the metal ball 304 contacts the two metal plates 303, and the two metal plates 303 are connected, which can connect the circuit of the buzzer 305 and the flashlight 306. The buzzer 305 emits a sound, and the flashlight 306 emits a flash to remind and prevent the boiler body 1 from dry burning. If you want to adjust the water level when the alarm is triggered, turn the screw 403 to adjust the position of the moving ball 407 in the boiler body 1. It is easy to use.

[0031] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
