DETAILED DESCRIPTION

[0020] The present embodiment is a kind of test device automatic water inlet device, with raw water pool and water inlet tank, wherein the water inlet tank is divided into water inlet part located at one end and water outlet part located at the other end by partition plate located in the middle part, and overflow passage is left at the top end of the partition plate, and interception filter screen is arranged corresponding to the overflow passage. In this example, the top of the water inlet tank is a cover plate that can be opened, which is convenient for cleaning and protecting the inside of the water inlet tank.

[0021] In this example, the water inlet part in the water inlet tank is connected to the raw water pool through a siphon water inlet pipe, and the siphon water inlet pipe is arranged in an inverted U shape. One end of the siphon water inlet pipe is the water inlet end, and the water inlet end is connected to the raw water pool through the water inlet pump. The other end of the siphon water inlet pipe is the water outlet end, and the elevation of the water outlet end is lower than that of the water inlet end. The water outlet end of the siphon water inlet pipe extends to the lower position in the water inlet part of the water inlet tank.

[0022] The water level switch (float ball liquid level meter) is arranged in the water inlet part of the water inlet tank in the embodiment, and the water level switch is electrically connected with the water pump. When the water level switch collects that the water level in the water inlet part is lower than the set value, a signal is sent to the control module of the water pump, the water pump starts to work, and the water pump stops working after working for a certain time, and the siphon effect formed in the siphon water pipe is used to continuously supply water for the water inlet tank.

[0023] The float ball valve (mechanical float ball valve) is arranged at the water outlet end of the siphon water pipe in the embodiment, the float ball valve can adjust the opening degree according to the water level of the water inlet part, and then the water inlet amount is controlled.

[0024] The water amount of the water inlet part in the water inlet tank is controlled by the cooperation of the water level switch and the float ball valve in the embodiment, the water level in the operation is maintained by using the float ball valve and the siphon principle after the water pump is started to supplement water for the first time, and the water level is actively supplemented by starting the water pump as a replacement when the float ball valve is damaged or blocked.

[0025] When the liquid level reaches the upper edge of the interception filter screen, the liquid surface position is the highest, at this time the water pump is closed, the raw water enters the water inlet part through the interception filter screen, at this time the water level floats between the upper edge and the lower edge of the interception filter screen, the float ball valve starts to work, the opening degree of the float ball valve is adjusted to ensure that the water level is not lower than the lower edge of the interception filter screen, and the water is actively supplemented again when the float ball liquid level meter detects that the water level is lower than the lower edge of the interception filter screen.

[0026] When the float ball valve is completely closed, the liquid level is flush with the upper edge of the interception filter screen, at this time the liquid surface is the highest, and when the float ball valve is completely opened, the liquid level is flush with the lower edge of the interception filter screen, at this time the liquid surface is the lowest, the mechanical float ball can effectively cooperate with the siphon principle to supplement the raw water, and the power consumption is saved.

[0027] The connection between the siphon water pipe and the water inlet part is located at the lower part of the water inlet part in the embodiment, and the siphon water pipe is reserved with 3-5 cm of impurity deposition space from the bottom of the tank, so that the impurities deposited in the lower part are not disturbed when the water is taken.

[0028] The filter screen is arranged at the water inlet end of the water pump in the embodiment, the water in the raw water pool is filtered for the first time when the water is taken, and the impurity content in the water is reduced in cooperation with the interception filter screen.

[0029] The above embodiments are only used for explaining the inventive concept of the application, and are not limited to the protection of the application, and any non-essential modification of the application by using the concept should fall within the protection scope of the application.
