Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen energy equipment testing devices, in particular to a temperature tester for hydrogen energy combustion equipment. Background Art

[0002] A water welder, also called a hydrogen-oxygen welder, uses water as a medium. Under the action of an alkaline catalyst, when an electric current is applied, an electrochemical reaction occurs in the water to generate hydrogen and oxygen. Using hydrogen as fuel and oxygen for combustion support, a hydrogen-oxygen flame is formed by igniting with a special hydrogen-oxygen flame gun to perform welding operations on workpieces.

[0003] The water welder needs to test the flame temperature of the welding torch to determine whether the welder can be used normally. Generally, a temperature tester is used for testing. However, in the prior art, usually after the flame is ignited, it is inserted into the test port, and the flame temperature is detected by a temperature sensor. The flow rate of the hydrogen-oxygen mixed gas is controlled by turning the knob at the head of the spray gun, thereby controlling the size of the flame. Before the first ignition, it is uncertain whether the gas flow rate is appropriate. Too large or too small a flow rate will cause failure to ignite, so there is a certain danger.

[0029] Embodiment 1:

[0030] Please refer to Figures 1-5 , the above technical solutions of the present invention will be described in detail through the following embodiments:

[0031] The temperature tester for hydrogen energy combustion equipment includes:

[0032] A test chamber 1, the test chamber 1 includes an outer shell 11, a chamber door 12 is rotatably installed on the front side of the outer shell 11 through a hinge, a fire-resistant lining 13 is provided inside the outer shell 11 and the chamber door 12, a temperature measurement component 2 is provided outside the chamber door 12, and a nozzle adjustment component 3 is provided outside the back of the outer shell 11.

[0033] The fire-resistant lining 13 can be made of fire-resistant bricks or fire-resistant cement and other materials, and is coated on the inner sides of the outer shell 11 and the chamber door 12.

[0034] The back of the test chamber 1 is provided with a test port 15, and the nozzle of the hydrogen energy combustion device is inserted into the test chamber 1 through the test port 15.

[0035] The diameter of the test port 15 is larger than the outer diameter of the nozzle of the hydrogen energy combustion device.

[0036] A spark plug 17 is threadedly installed at the top of the test chamber 1 and directly in front of the test port 15. A exhaust fan 16 is fixedly installed on the front top surface of the test chamber 1 by bolts on the front side of the spark plug 17.

[0037] When the spark plug 17 works, it can generate an electric spark to achieve ignition. The exhaust fan 16 is used to exhaust the gas inside the test chamber 1. The air outlet of the exhaust fan 16 can be connected to the outside through a pipeline.

[0038] A viewing window 14 is provided through the upper part of the middle of the box door 12.

[0039] The center of the viewing window 14 should be flush with the center of the test port 15.

[0040] The temperature measurement component 2 includes a temperature measurement probe 24. The temperature measurement probe 24 is connected with a height adjustment component, and the height adjustment component is used to adjust the height of the temperature measurement probe 24.

[0041] The temperature measurement probe 24 adopts an infrared pyrometer. Since hydrogen combustion in oxygen can generate a high temperature of about 3000 °C, ordinary thermocouples cannot withstand it for a long time.

[0042] The height adjustment component is located outside the viewing window 14. The height adjustment component includes two slide rails 21. The two slide rails 21 are installed in parallel on the left and right sides of the viewing window 14. A slider 22 is slidably installed on the slide rails 21. A fixing screw 23 is provided on the outside of the slider 22. The temperature measurement probe 24 is fixedly installed at the center of the top surface of the slider 22 through a bracket.

[0043] The fixing screw 23 is used to contact the surface of the slide rail 21 and fix the slider 22 by using friction. After loosening the fixing screw 23, the slider 22 can slide along the slide rail 21, thereby adjusting the height of the temperature measurement probe 24 to make the height of the temperature measurement probe 24 the same as the height of the flame generated by the hydrogen energy combustion device, improving the test accuracy.

[0044] The nozzle adjustment component 3 includes a nozzle bracket 31. The nozzle bracket 31 is used to install the nozzle of the hydrogen energy combustion device. Two first motors 36 are installed on both sides of the nozzle bracket 31 through a horizontal adjustment component. The output shaft of the first motor 36 is clamped with an adjustment sleeve 37. The adjustment sleeve 37 is used to connect with the knob of the nozzle. The first motor 36 is used to drive the adjustment sleeve 37 to rotate. The horizontal adjustment component is used to adjust the distance between the first motor 36 and the nozzle of the hydrogen energy combustion device. The nozzle bracket 31 is fixedly installed directly below the outside of the test port 15.

[0045] The nozzle support 31 is used to be snap-connected to the nozzle of the hydrogen energy combustion device, thereby fixing the nozzle of the hydrogen energy combustion device. The first motor 36 is a stepper motor.

[0046] The horizontal adjustment assembly includes two guide rods 32. A motor support 33 is slidably connected to the middle of each guide rod 32 through a sliding sleeve 34. The first motor 36 is fixedly installed between the two motor supports 33. The head of the guide rod 32 is threadedly connected with an adjusting nut 35.

[0047] The first motor 36 can slide along the guide rod 32 through the sliding sleeve 34. Since the adjusting nut 35 is threadedly connected to the head of the guide rod 32, rotating the adjusting nut 35 can drive the adjusting nut 35 to move along the guide rod 32, thereby controlling the position of the adjusting nut 35 on the guide rod 32, and further controlling the moving distance of the first motor 36.

[0048] An elastic inner lining 38 is provided inside the side of the adjusting sleeve 37 away from the first motor 36. The elastic inner lining 38 is beveled near the edge of the adjusting sleeve 37.

[0049] The elastic inner lining 38 can be made of a rubber part. After the adjusting sleeve 37 is sleeved on the knob of the nozzle of the hydrogen energy combustion device, the elastic inner lining 38 abuts against the knob, thereby wrapping the knob.

[0050] When the first motor 36 works, it can drive the adjusting sleeve 37 to rotate through the output shaft, thereby driving the knob to rotate through the elastic inner lining 38, and realizing the control of the air flow size of the nozzle.

[0051] In this embodiment, when an operator uses this device, the nozzle of the hydrogen energy combustion device is snapped into the nozzle support 31, and it is ensured that the nozzle is inserted into the test port 15.

[0052] Push the first motor 36 so that the first motor 36 slides along the guide rod 32 until the adjusting sleeve 37 is sleeved outside the nozzle knob. Rotate the adjusting nut 35 to make the adjusting nut 35 move towards the sliding sleeve 34 direction, so that the elastic inner lining 38 abuts against the knob.

[0053] Loosen the fixing screw 23, and use the sliding of the slider 22 to adjust the height of the temperature measuring probe 24 so that the height of the temperature measuring probe 24 is the same as the center height of the nozzle of the hydrogen energy combustion device.

[0054] Start the first motor 36, use the first motor 36 to drive the adjusting sleeve 37, and thereby drive the knob to rotate through the elastic inner lining 38, and the hydrogen-oxygen mixed gas starts to be ejected from the nozzle outlet.

[0055] Energize the spark plug 17 to generate an electric spark to ignite the mixed gas.

[0056] Use the temperature measuring probe 24 to detect the flame temperature.

[0057] By controlling the rotation angle and number of turns of the output shaft of the first motor 36, the rotation angle and number of turns of the control knob are controlled to control the gas flow rate, and further to control the flame size.

[0058] Before the flame is ignited, it is necessary to control the exhaust fan 16 to work to discharge the mixed gas in the test chamber 1 to avoid too high hydrogen concentration.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
