Description

Technical Field

[0001] The invention relates to the technical field of hydrogen testing, and in particular to a device for testing the hydrogen production amount of hydrogen-producing products. Background Art

[0002] Hydrogen-producing products refer to various products that can produce hydrogen. They can be divided into water electrolysis hydrogen production equipment, fossil fuel hydrogen production equipment and renewable energy hydrogen production equipment according to the way they produce hydrogen. Common hydrogen-producing products mainly include but are not limited to hydrogen water machines, hydrogen water cups and hydrogen absorption machines, etc. These products are widely used in energy, chemical, medical, food and other fields.

[0003] In order to ensure the stability and consistency of the quality of hydrogen-producing products, it is necessary to verify through testing whether the hydrogen-producing products can achieve the expected hydrogen production. Moreover, hydrogen is a flammable and explosive gas, and its concentration that is too high or too low may pose a safety hazard. Therefore, in order to ensure the safety of users during use, it is also necessary to verify through testing whether the purity of the hydrogen produced by hydrogen-producing products meets the standards.

[0004] Therefore, a hydrogen production amount testing device for hydrogen-producing products is proposed to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a device for testing the amount of hydrogen produced by hydrogen-producing products to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a hydrogen production amount testing device for hydrogen-producing products, comprising a workbench, a measuring mechanism is arranged on the top of the workbench, and a connecting mechanism is arranged on the measuring mechanism;

[0007] The measuring mechanism comprises a water tank, a measuring cylinder is placed in the water tank, one side of the measuring cylinder is fixedly connected to an air inlet pipe, a holder is fixedly connected to the top of the workbench, a pump-suction type hydrogen detector is clamped on the holder, and the other side of the measuring cylinder is fixedly connected to a vent pipe;

[0008] The connecting mechanism includes a fixing ring, the internal thread of the fixing ring is connected to a first connecting ring, one side of the first connecting ring is fixedly connected to a first connecting hard pipe, the outer side of the ventilation pipe is fixedly connected to a mounting ring, the interior of the mounting ring is provided with a mounting cavity, the interior of the mounting cavity is fixedly connected to a spring, one side of the spring is fixedly connected to a push block, the interior of the mounting ring is movably connected to a second connecting hard pipe, and the outer side of the second connecting hard pipe is fixedly connected to a clamping block.

[0009] Preferably, the water tank is fixedly connected to the top of the workbench, the water tank is transparent in design and a drain pipe is fixedly connected to the rear side of the inner wall thereof.

[0010] Preferably, the measuring tube is transparent and has scales on its surface, and the air inlet pipe is Z-shaped and one end extends to the outside of the water tank.

[0011] Preferably, the model of the pump-suction type hydrogen gas detector is "gt-", an air inlet is provided on one side of the pump-suction type hydrogen gas detector, the fixing ring is fixedly connected to the outside of the air inlet, and a first sealing ring is fixedly connected between the air inlet and the fixing ring.

[0012] Through the above technical solution, under the action of the first sealing ring, the hydrogen generated by the hydrogen-producing product can be prevented from leaking from the air inlet end of the pump-suction hydrogen detector, thereby affecting the detection of hydrogen concentration.

[0013] Preferably, a connecting hose is fixedly connected between the first connecting rigid tube and the second connecting rigid tube, and the number of the clamping blocks is two and they are symmetrically distributed on the outer side of the second connecting rigid tube.

[0014] Preferably, the number of the installation cavities is two and they are symmetrically opened inside the installation ring, one side of the installation ring is provided with a movable groove adapted to the moving trajectory of the card block, and the installation ring is provided with a card slot adapted to the card block, and the movable groove and the card slot are both connected to the installation cavity.

[0015] Preferably, an arc groove matching the rotation track of the clamping block is formed on the inner side of the mounting ring, the arc groove is connected with the mounting cavity, and the moving distance of the push block is slightly larger than the diameter of the clamping groove.

[0016] With the above technical solution, since the movable distance of the push block is slightly larger than the diameter of the card slot, when the card block needs to be withdrawn from the card slot, the card block can be pushed toward one side of the push block to achieve the purpose of disengaging the card block from the card slot.

[0017] Preferably, one end of the ventilation pipe located inside the mounting ring is fixedly connected to a second sealing ring, and one end of the second connecting rigid pipe located inside the mounting ring is fixedly connected to a third sealing ring that fits with the second sealing ring.

[0018] Through the above technical solution, with the coordinated use of the second sealing ring and the third sealing ring, it is possible to prevent the hydrogen generated by the hydrogen-producing products from leaking from the connection between the vent pipe and the second connecting hard pipe.

[0019] Preferably, a supporting mechanism is provided on the measuring mechanism, and the supporting mechanism comprises a supporting leg fixedly connected to the inner bottom wall of the water tank, a supporting ring is fixedly connected to the supporting leg, and a supporting groove matched with the supporting ring is provided at the bottom of the measuring cylinder.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0021] First, the present invention fills a water tank with clean water, and places a measuring tube filled with water into the water tank, ensuring that the clean water in the water tank covers the bottom opening of the measuring tube, connects an air inlet pipe with a hydrogen-producing product, passes hydrogen into the measuring tube, and tests the hydrogen production by observing the amount of water discharged from the measuring tube, connects the air vent pipe with the air inlet of a pump-suction hydrogen detector, and verifies the hydrogen concentration generated by the hydrogen-producing product by the pump-suction hydrogen detector.

[0022] Second, the present invention realizes the quick connection of the connecting hose and the pump-suction type hydrogen detector by rotating the first connecting ring to install it on the fixed ring, and moves the clamping block on the second connecting hard tube inward along the movable groove on the mounting ring until the clamping block fits with the push block and continues to move inward to compress the spring. After the spring is compressed to the tightest, the clamping block is just in the arc groove, and the clamping block is rotated along the arc groove to connect the second connecting hard tube. When the clamping block is rotated to the clamping groove, the clamping block is pushed into the clamping groove by the push block under the elastic force of the spring, thereby completing the quick connection of the second connecting hard tube, thereby realizing the quick connection of the connecting hose.

[0023] Thirdly, the present invention inserts the support groove on the measuring tube into the support ring, and the supporting legs provide stable support for the entire measuring tube, thereby ensuring the stability of the measuring tube during the process of hydrogen generation on both sides.
