[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water replenishing device for water electrolysis hydrogen production equipment, comprising a base, a water tank is installed on the upper end of the base, and the water tank is connected to the electrolysis box through a water replenishing pipe, and the electrolysis box is installed on the upper end of the base; a sealing plate, the sealing plate and the tail end of the water replenishing pipe are distributed in front and back correspondence, and guide blocks are fixedly installed at both ends of the sealing plate, the guide blocks are nested on the inner side of the second slide groove, and the second slide groove is opened on the inner side of the electrolysis box, and a telescopic spring is connected between the guide block and the inner wall of the second slide groove; a filter net, the filter net passes through the inner side of the through groove, and the through groove is opened on the inner side of the water replenishing pipe.

[0014] Compared with the prior art, the utility model has the beneficial effect that the water replenishing device for water electrolysis hydrogen production equipment is provided with:

[0015] 1. Automatic water replenishment structure. This structure is achieved by installing a floating plate inside the electrolytic box, and the floating plate is stabilized by multiple groups of adjusting rods. When the liquid level inside the electrolytic box rises, the floating plate will float up through buoyancy, thereby driving the adjusting rod at its bottom to rotate. The rotation of the adjusting rod will drive the sliding block at the tail end to slide along the inside of the first slide groove. The sliding of the sliding block drives the traction rope to move together. The traction rope generates traction force on the connecting rod, so that the guide block squeezes the telescopic spring and slides downward along the second slide groove, so that the connected sealing plate blocks the tail end of the water replenishment pipe, so that the water replenishment pipe is in a closed state, and the water replenishment stops;

[0016] Furthermore, when the liquid level inside the electrolytic box drops, the floating plate loses buoyancy and moves downward, so that the sliding block at the tail end of the adjusting rod slides outward along the inside of the first slide groove. When the sliding block slides outward, the traction rope on the outside thereof will be in a relaxed state. At this time, the connecting rod loses traction, and the guide block on the outside thereof will be reset by the elastic force of the telescopic spring, so that the connected sealing plate moves upward. At this time, the sealing plate and the tail end of the water supply pipe are in a misaligned state, and the tail end of the water supply pipe is in an open state, so that the inside of the electrolytic box is replenished with water. Through the above operation, the effect of automatically replenishing water when the liquid level inside the electrolytic box is too low and stopping replenishing water when the liquid level is too high is achieved.

[0017] 2. Filter structure: This structure opens a through groove on the inner side of the water supply pipe. When the water supply operation is performed, the filter net is inserted into the inner side of the through groove, so that the water flowing through the inner side of the water supply pipe is filtered by the filter net, thereby improving the quality of electrolyzed water;

[0018] Furthermore, when the filter needs to be cleaned or replaced, the clamping rod is manually pulled to separate the tail end of the clamping rod from the clamping slot inside the filter. After separation, the filter is in an active state and can be taken out for replacement. The replaced filter is then inserted into the inner side of the through slot and the clamping rod is released. The clamping rod is reset by the elastic force of the reset spring, so that the tail end of the clamping rod is engaged with the corresponding clamping slot. The filter is fixed to the inner side of the through slot through the engagement of the clamping slot and the tail end of the clamping rod. BRIEF DESCRIPTION OF THE DRAWINGS
