[0002] Hydrogen combustion equipment is a device specifically designed for burning hydrogen. Its key function is to ensure that hydrogen is mixed with air or oxygen and burned safely and efficiently.
[0003] In existing hydrogen burners, the height of the combustion nozzle is fixed and cannot be changed according to actual usage, which reduces the practicality of the hydrogen burner. Utility Model Content
[0004] This utility model proposes a hydrogen combustion device to overcome the shortcomings of existing technologies.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hydrogen combustion device, comprising a hydrogen generator, an outlet pipe fixedly connected to one side of the hydrogen generator, a nozzle fixedly connected to one end of the outlet pipe, an ignition device provided at the outlet of the nozzle, an adjustment device provided on the surface of the hydrogen generator, the adjustment device comprising a motor, the motor fixedly connected to one side of the hydrogen generator, a screw fixedly connected to the output end of the motor, a pad provided at one end of the screw, the pad fixedly connected to the hydrogen generator, a U-shaped plate threadedly connected to the arc surface of the screw, and rotating rods rotatably connected to both arms of the U-shaped plate, with the ends of the two rotating rods close to each other fixedly connected to the nozzle.
[0006] The aforementioned components achieve the following effect: When the nozzle height needs to be adjusted, the operator turns on the motor, which drives the screw to rotate. The screw moves the U-shaped plate up and down, and the nozzle moves along with the U-shaped plate. Once the U-shaped plate and nozzle reach the appropriate height, the operator turns off the motor. Then, the operator uses a hydrogen generator to deliver hydrogen to the outlet pipe. The hydrogen in the outlet pipe enters the nozzle and is ignited by the ignition device on the nozzle. The hydrogen then burns. By adjusting the device, the nozzle height can be adjusted, allowing the hydrogen combustion equipment to adapt to items of different heights, thereby improving the practicality of the hydrogen combustion equipment.
[0007] Preferably, a bearing is provided on the upper surface of the pad, the inner ring of the bearing is fixedly connected to the screw, and the outer ring of the bearing is fixedly connected to the screw.
[0008] The effect achieved by the above components is to improve the stability of screw rotation by setting bearings, and to prevent screw from shaking.
[0009] Preferably, the surface of the U-shaped plate has two mutually symmetrical limiting rods that slide through it, and the two ends of the limiting rods are fixedly connected to the hydrogen generator.
[0010] The effect achieved by the above components is that by setting the limit rod, the movement direction of the U-shaped plate is restricted, preventing the U-shaped plate from rotating and improving the stability of the U-shaped plate movement.
[0011] Preferably, the arc surface of the air outlet pipe is fitted with a fixing ring, and the fixing ring is fixedly connected to the nozzle by means of a bracket.
[0012] The effect achieved by the above-mentioned components is that by setting a retaining ring, the air outlet pipe is limited, thus preventing excessive stress at the connection between the air outlet pipe and the nozzle, which could lead to breakage.
[0013] Preferably, one end of one of the rotating rods is provided with an auxiliary device, the auxiliary device including a baffle, the baffle being fixedly connected to the end of the rotating rod located outside the U-shaped plate, a spring being fixedly connected to one side of the baffle, a circular plate being fixedly connected to one end of the spring, the circular plate being slidably connected to the rotating rod, and an insertion rod being fixedly connected to the side of the circular plate away from the baffle, and a plurality of insertion holes being evenly opened on the U-shaped plate corresponding to the insertion rod, the plurality of insertion holes being circumferentially distributed, and the size of the insertion rod being adapted to the size of the insertion hole.
[0014] The aforementioned components achieve the following effect: When the nozzle angle needs to be adjusted, the operator first pulls the circular plate, which moves the insert rod away from the insertion hole. The spring on the baffle then contracts. The operator then rotates the circular plate, which in turn rotates the rotating rod, causing the nozzle to rotate. Once the nozzle is adjusted to the appropriate angle, the operator releases the circular plate. Under the spring's restoring force, the circular plate moves towards the U-shaped plate, and the insert rod on the circular plate inserts into the insertion hole of the U-shaped plate, thus fixing the rotating rod. This auxiliary device achieves the effect of adjusting the nozzle angle, allowing the nozzle to adapt to different environments and improving the practicality of the hydrogen combustion equipment.
[0015] Preferably, the arc surface of the rotating rod is fixedly connected with a plurality of limiting members, and the plurality of limiting members are distributed in a circle.
[0016] The effect achieved by the above components is that by setting the limiting component, the movement direction of the circular plate relative to the rotating rod is restricted, thus preventing rotation between the circular plate and the rotating rod and improving the stability of the circular plate's movement.
[0017] Preferably, one end of the insertion rod is fixedly connected to a pointed protrusion, the tip of which is away from the insertion rod.
[0018] The effect achieved by the above-mentioned components is that the pointed protrusions make it easier for workers to insert the plug into the socket of the U-shaped plate, thus providing convenience for the workers.
[0019] Preferably, the circular plate has a plurality of circular arc grooves evenly distributed on its arc surface, and the plurality of circular arc grooves are distributed in a circular pattern.
[0020] The effect achieved by the above-mentioned components is that by setting the arc groove, it is convenient for the staff to insert their fingers into the arc groove to operate the circular plate, which brings convenience to the staff in moving the circular plate.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] When the nozzle height needs to be adjusted, the operator turns on the motor, which drives the screw to rotate. The screw moves the U-shaped plate up and down, and the nozzle moves along with the U-shaped plate. Once the U-shaped plate and nozzle are at the appropriate height, the operator turns off the motor. Then, the operator uses a hydrogen generator to deliver hydrogen to the outlet pipe. The hydrogen in the outlet pipe enters the nozzle and is ignited by the ignition device on the nozzle. The hydrogen then burns. By adjusting the device, the nozzle height can be adjusted, allowing the hydrogen combustion equipment to adapt to items of different heights, thereby improving the practicality of the hydrogen combustion equipment.

Detailed Implementation

[0029] Reference Figure 1-4 As shown, the adjusting device 4 includes a motor 41, which is fixedly connected to one side of the hydrogen generator 1. A screw 42 is fixedly connected to the output end of the motor 41. A pad 45 is provided at one end of the screw 42. The pad 45 is fixedly connected to the hydrogen generator 1. A U-shaped plate 43 is threadedly connected to the arc surface of the screw 42. Rotating rods 44 are rotatably connected to both arms of the U-shaped plate 43. The ends of the two rotating rods 44 that are close to each other are fixedly connected to the nozzle 3. When the height of nozzle 3 needs to be adjusted, the operator turns on motor 41. Motor 41 drives screw 42 to rotate, and screw 42 moves U-shaped plate 43 up and down. Nozzle 3 moves along with U-shaped plate 43. When U-shaped plate 43 and nozzle 3 reach the appropriate height, the operator turns off motor 41. Then, the operator uses hydrogen generator 1 to deliver hydrogen to outlet pipe 2. The hydrogen in outlet pipe 2 enters nozzle 3 and is ignited by the ignition device on nozzle 3. The hydrogen then burns. The height of nozzle 3 can be adjusted by adjusting device 4, making the hydrogen combustion equipment adaptable to items of different heights, thereby improving the practicality of the hydrogen combustion equipment.
[0030] Reference Figure 1-4 As shown, a bearing 46 is provided on the upper surface of the pad 45. The inner ring of the bearing 46 is fixedly connected to the screw 42, and the outer ring of the bearing 46 is also fixedly connected to the screw 42. The bearing 46 improves the stability of the screw 42's rotation and prevents it from shaking. Two symmetrical limiting rods 47 slide through the surface of the U-shaped plate 43, and both ends of the limiting rods 47 are fixedly connected to the hydrogen generator 1. The limiting rods 47 restrict the movement direction of the U-shaped plate 43, preventing it from rotating and improving its stability. A fixing ring 48 is fitted onto the arc surface of the outlet pipe 2, and the fixing ring 48 is fixedly connected to the nozzle 3 via a bracket. The fixing ring 48 limits the movement of the outlet pipe 2, preventing excessive force at the connection between the outlet pipe 2 and the nozzle 3, which could lead to breakage.
[0031] Reference Figure 1-4As shown, one end of one of the rotating rods 44 is provided with an auxiliary device 5. The auxiliary device 5 includes a baffle 51, which is fixedly connected to the end of the rotating rod 44 located outside the U-shaped plate 43. A spring 52 is fixedly connected to one side of the baffle 51, and a circular plate 53 is fixedly connected to one end of the spring 52. The circular plate 53 is slidably connected to the rotating rod 44. A plug rod 54 is fixedly connected to the side of the circular plate 53 away from the baffle 51. Several plug holes 55 are evenly opened on the U-shaped plate 43 corresponding to the plug rod 54. The several plug holes 55 are circumferentially distributed, and the size of the plug rod 54 is adapted to the size of the plug hole 55. When the angle of the nozzle 3 needs to be adjusted, the operator first pulls the circular plate 53. The circular plate 53, along with the insert rod 54, moves away from the insertion hole 55, and the spring 52 on the baffle 51 retracts. Then, the operator rotates the circular plate 53, which in turn rotates the rotating rod 44, causing the nozzle 3 to rotate. Once the nozzle 3 is adjusted to the appropriate angle, the operator releases the circular plate 53. Under the restoring force of the spring 52, the circular plate 53 moves towards the U-shaped plate 43, and the insert rod 54 on the circular plate 53 inserts into the insertion hole 55 of the U-shaped plate 43, thus fixing the rotating rod 44. The auxiliary device 5 achieves the effect of adjusting the angle of the nozzle 3, making it easier for the nozzle 3 to adapt to different environments, thereby improving the practicality of the hydrogen combustion equipment.
[0032] Reference Figure 1-4 As shown, several limiting members 58 are fixedly connected to the arc surface of the rotating rod 44, and these limiting members 58 are distributed circumferentially. By setting the limiting members 58, the movement direction of the circular plate 53 relative to the rotating rod 44 is restricted, preventing rotation between the circular plate 53 and the rotating rod 44 and improving the stability of the circular plate 53's movement. A pointed protrusion 56 is fixedly connected to one end of the insertion rod 54, with the tip of the protrusion 56 away from the insertion rod 54. The pointed protrusion 56 facilitates the insertion of the insertion rod 54 into the insertion hole 55 of the U-shaped plate 43, providing convenience for the operator. Several arc grooves 57 are evenly distributed on the arc surface of the circular plate 53, and these arc grooves 57 are distributed circumferentially. The arc grooves 57 facilitate the operation of the circular plate 53 by inserting fingers into them, providing convenience for the operator to move the circular plate 53.
[0033] Working principle: When the height of nozzle 3 needs to be adjusted, the operator turns on motor 41. Motor 41 drives screw 42 to rotate. Bearing 46 on pad 45 improves the stability of screw 42's rotation. Screw 42 moves up and down with U-shaped plate 43, and nozzle 3 moves along with U-shaped plate 43. When U-shaped plate 43 and nozzle 3 reach the appropriate height, the operator turns off motor 41. Then, the operator uses hydrogen generator 1 to deliver hydrogen to outlet pipe 2. The hydrogen in outlet pipe 2 enters nozzle 3 and is ignited by the ignition device on nozzle 3. The hydrogen then burns. The adjustment device 4 achieves the effect of adjusting the height of nozzle 3, making the hydrogen combustion equipment adaptable to items of different heights, thereby improving the practicality of the hydrogen combustion equipment.
[0034] When the angle of the nozzle 3 needs to be adjusted, the operator first pulls the circular plate 53 through the arc groove 57. The circular plate 53, along with the insertion rod 54, moves away from the insertion hole 55, and the spring 52 on the baffle 51 retracts. Then, the operator rotates the circular plate 53, which in turn rotates the rotating rod 44, causing the nozzle 3 to rotate. Once the nozzle 3 is adjusted to the appropriate angle, the operator releases the circular plate 53. Under the restoring force of the spring 52, the circular plate 53 moves towards the U-shaped plate 43. The insertion rod 54 on the circular plate 53, with the help of the pointed protrusion 56, inserts into the insertion hole 55 of the U-shaped plate 43, thus fixing the rotating rod 44. The auxiliary device 5 achieves the effect of adjusting the angle of the nozzle 3, making it easier for the nozzle 3 to adapt to different environments, thereby improving the practicality of the hydrogen combustion equipment.
