DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0026] As Figures 1-3 Indicated, hydrogen fuel equipment electrolytic water automatic supply device, including water supply assembly, as Figure 1As shown, the water supply assembly includes a water supply tank 1 for storing raw water, a filter 2 for pre-filtering the raw water, and a deionization machine 3 for deionizing the pre-filtered water, the water supply tank 1 is connected to the filter 2 at the output end, the filter 2 is connected to the deionization machine 3 at the output end, the deionization machine 3 is connected to the water storage bucket 4 at the input end, and the water pump is arranged inside the water supply tank 1 for conveying raw water to the filter 2. The water supply tank 1 can send raw water into the filter 2, and the filter 2 can pre-filter the raw water, and then the pre-filtered water is sent into the deionization machine 3 to realize secondary filtration and deionization.

[0027] The deionization machine 3 is connected to the water storage bucket 4, and the water storage bucket 4 is connected to the electrolytic water conveying mechanism 5, which includes a conveying water pipe 501 in communication with the water storage bucket 4, a plurality of branch water pipes 502 are fixedly arranged on the conveying water pipe 501, and each branch water pipe 502 is fixedly connected to an electrolytic tank 6 at the other end. The electrolytic tank 6 is provided with a liquid level detection assembly for detecting the liquid level of the electrolytic solution, and each branch water pipe 502 is provided with a group of electromagnetic valves 503. The bottom horizontal height of the water storage bucket 4 is greater than the top horizontal height of the electrolytic tank 6. The electrolytic water enters the conveying water pipe 501 under the action of gravity, enters each electrolytic tank 6 through the branch water pipe 502, and when the liquid level detection assembly detects that the liquid level reaches a certain height, the electromagnetic valve 503 is automatically closed, thereby avoiding excessive delivery of electrolytic water. Because the horizontal height of the water storage bucket 4 is greater than that of the electrolytic tank 6, the water in the electrolytic tank 6 is prevented from flowing back, thereby affecting the water quality in the conveying water pipe 501 (in order to improve the conductivity, NaOH / KOH solution is added to the electrolytic water in the electrolytic tank 6).

[0028] The liquid level detection assembly includes a first capacitive liquid level sensor 601 and a second capacitive liquid level sensor 602 fixedly arranged on the side of the electrolytic tank 6 for detecting the liquid level of the electrolytic water, and the first capacitive liquid level sensor 601 is arranged above the second capacitive liquid level sensor 602. When the electrolytic water is insufficient, the liquid level of the electrolytic water is lower than the horizontal height of the second capacitive liquid level sensor 602, the electromagnetic valve 503 is opened, so that the water in the conveying water pipe 501 enters the electrolytic tank 6. When the liquid level overflows the first capacitive liquid level sensor 601, the first capacitive liquid level sensor 601 outputs a signal, and the electromagnetic valve 503 is closed, thereby preventing excessive delivery of electrolytic water.

[0029] The delivery water pipe 501 is provided with a water release valve 504 near one end of the water storage barrel 4 and a water discharge valve 505 away from the other end of the water storage barrel 4. When the electrolytic water in the electrolytic tank 6 needs to be completely replaced, the water discharge valve 505 and all the electromagnetic valves 503 are opened, so that the electrolytic water flows into the delivery water pipe 501 along the water distribution pipe 502 and is discharged through the water discharge valve 505, realizing the discharge of the electrolytic water. The bottom of the electrolytic tank 6 is provided with a water collecting groove 603, and each group of water distribution pipes 502 is connected with the corresponding water collecting groove 603, so as to ensure that the electrolytic water in the electrolytic tank 6 can be fully discharged. The raw water in the water storage barrel 4 also needs to be periodically emptied, so as to avoid that the electrolytic water is closed for a long time, affecting the effect of deionization, or the electrolytic water surface produces floating objects, affecting the quality of the raw water.

[0030] As shown in Figure 1 The water storage barrel 4 is provided with a storage capacity scale 401 for observing the storage capacity, which includes a glass plate arranged on one side of the water storage barrel 4 and a scale marked on the glass plate. The electrolytic water storage capacity in the water storage barrel 4 can be observed through the storage capacity scale 401.

[0031] In a specific embodiment, the output end of the water storage barrel 4 is connected with a main pipe 506, and the delivery water pipe 501 is provided with multiple groups, each group of the delivery water pipe 501 is connected with the main pipe 506, and the electrolytic water in the water storage barrel 4 is sent into each delivery water pipe 501 through the main pipe 506, and then enters the corresponding water distribution pipe 502 through multiple groups of the delivery water pipe 501, and finally enters the electrolytic tank 6, so as to realize the effect of large-scale water distribution. The main pipe 506 is provided with manually opened and closed valves at both ends, which are used for periodically discharging raw water and maintaining the inside of the water storage barrel 4.

[0032] In a specific embodiment, the water release valve 504 and the water discharge valve 505 are both manually opened and closed valves, which can avoid affecting the work of the electrolytic tank 6 due to the mistake of the staff.

[0033] In order to facilitate the understanding of the embodiment of the present scheme by the person skilled in the art, the working principle of the embodiment of the present scheme will be described in combination with a specific application scene:

[0034] In use, the water supply tank 1 can send raw water into the filter 2, and the raw water is pre-filtered by the filter 2, and then the pre-filtered water is sent into the ionizer 3 to realize secondary filtration and ionization, and then is stored in the water storage bucket 4. When the electrolytic water in the electrolytic tank 6 is insufficient, that is, the electrolytic water level is lower than the second capacitor liquid level sensor 602, the electromagnetic valve 503 is opened, and the electrolytic water enters the conveying water pipe 501 under the action of gravity, and then enters each group of electrolytic tanks 6 through the water distribution pipe 502. When the liquid level exceeds the first capacitor liquid level sensor 601, the first capacitor liquid level sensor 601 outputs a signal, and the electromagnetic valve 503 is closed, so as to avoid excessive delivery of electrolytic water. Since the water storage bucket 4 is higher than the electrolytic tank 6, the water in the electrolytic tank 6 is prevented from flowing back, so as to affect the water quality in the conveying water pipe 501 (in order to improve the conductivity, NaOH / KOH solution is added to the electrolytic water in the electrolytic tank 6);

[0035] When the electrolytic water in the electrolytic tank 6 needs to be replaced, the water outlet valve 504, the drain valve 505 and all the electromagnetic valves 503 are opened, so that the electrolytic water enters the conveying water pipe 501 through the water distribution pipe 502, and is output through the drain valve 505, so as to realize the discharge of the electrolytic water. The electrolytic water in the water storage bucket 4 also needs to be discharged regularly, so as to avoid the electrolytic water being closed for a long time, affecting the ionization effect, or the raw water level producing floating objects, affecting the raw water quality. When the water storage bucket 4 is emptied, the water outlet valve 504 and the drain valve 505 are opened, and the electrolytic water in the water storage bucket 4 is discharged through the conveying water pipe 501 under the action of gravity.

[0036] The above describes one embodiment of the present application in detail, but the above description is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made according to the scope of the present application should still belong to the patent coverage range of the present application.
