Specific implementation

[0025] In order to facilitate the understanding of those skilled in the art, the utility model is further explained below in combination with examples and drawings, and the content mentioned in the implementation is not limited to the utility model.

[0026] As Figure 1 Indicated, in the embodiment, including transparent liquid level cylinder 1 and float 5, the float 5 is located in transparent liquid level cylinder 1, the lower right end of transparent liquid level cylinder 1 is communicated with water inlet valve 2, and the upper right end of transparent liquid level cylinder 1 is communicated with water outlet valve 3, the right side of water inlet valve 2 and water outlet valve 3 is communicated with flange plate 16, the right side of flange plate 16 is connected with rubber soft gasket 17, the middle part in transparent liquid level cylinder 1 is fixed with sensing connecting rod 4, the float 5 is slidably sleeved on the periphery of sensing connecting rod 4, the lower end of the periphery of sensing connecting rod 4 is fixedly sleeved with support plate 6, the support plate 6 is connected with waterproof touch switch 7, the lower end of transparent liquid level cylinder 1 is installed with alarm 9.

[0027] When the water ring vacuum pump liquid level is monitored by the liquid level gauge, the water inlet valve 2 and the water outlet valve 3 are both communicated with the water ring vacuum pump, and in this process, the water inlet valve 2 and the water outlet valve 3 are connected with the vacuum pump through the flange plate 16. Since the rubber soft gasket 17 is arranged on the flange plate 16, the shock is reduced through the rubber soft gasket 17, which is beneficial to eliminate the vibration transmission and plays a buffering role for the in-situ liquid level gauge, thereby increasing the service life. Moreover, the liquid in the water ring vacuum pump enters the transparent liquid level cylinder 1 through the water inlet valve 2, and the excess water enters the water ring vacuum pump again through the water outlet valve 3. When the liquid level rises, the float 5 is floated by the liquid, and when the liquid level drops, the float 5 is lowered by the liquid, thereby facilitating the monitoring of the liquid level in the water ring vacuum pump through the up-down movement of the float 5. Moreover, the float 5 slides up and down along the sensing connecting rod 4, thereby avoiding the shaking of the float 5 due to external vibration and effectively ensuring the stability of the float 5 when measuring the liquid level.

[0028] As shown in Figure 1 , 3 , in the embodiment, the transparent liquid level cylinder 1 is provided with a storage battery 8 at the lower end, and the storage battery 8, the waterproof micro switch 7 and the alarm 9 are connected in series.

[0029] When the liquid level in the water ring vacuum pump drops, the float 5 will also drop with the liquid level of the transparent liquid level cylinder 1. If the liquid level in the water ring vacuum pump is insufficient, the float 5 will contact the waterproof micro switch 7 downward, the waterproof micro switch 7 is started, and the storage battery 8 supplies power to the alarm 9 to start. Therefore, the waterproof micro switch 7 controls the alarm 9 to emit an alarm sound, which is beneficial to timely remind the user that the liquid flow of the water ring vacuum pump is insufficient, and the user is beneficial to timely adjust the liquid level in the water ring vacuum pump to the normal state.

[0030] As shown in Figure 1 , 2 , 4, in the embodiment, the transparent liquid level cylinder 1 is provided with an annular brush 10 at the bottom, the annular brush 10 is fixed with a pull rod 11 at the upper end, the pull rod 11 slides through the transparent liquid level cylinder 1, the pull rod 11 is fixed with a handle 12 at the upper end, and the transparent liquid level cylinder 1 is communicated with a waste liquid valve 15 at the lower end.

[0031] When it is necessary to clean the impurities on the inner wall of the transparent liquid level cylinder 1, the annular brush 10 is arranged in contact with the inner wall of the transparent liquid level cylinder 1, and the handle 12 is pulled up and down to move the annular brush 10 up and down, thereby sweeping and cleaning the inner wall of the transparent liquid level cylinder 1. Therefore, the impurities on the inner wall of the transparent liquid level cylinder 1 can be conveniently and quickly cleaned. After the water inlet valve 2 and the water outlet valve 3 are closed and the waste liquid valve 15 is opened, the cleaned impurities are discharged through the waste liquid valve 15, thereby preventing the impurities from being difficult to clean due to long-term accumulation on the inner wall of the transparent liquid level cylinder 1, and facilitating the observation clarity of the transparent liquid level cylinder 1.

[0032] As shown inFigure 1 、 4 As shown in the figure, in the embodiment, the upper end of the transparent liquid level cylinder 1 is connected with a magnet block 13, the lower end of the handle 12 is connected with a magnetic attraction plate 14, and the magnet block 13 and the magnetic attraction plate 14 are attracted to each other.

[0033] When the annular brush 10 is not used, the annular brush 10 is located at the bottom of the transparent liquid level cylinder 1, and the magnetic attraction plate 14 is attracted by the magnet block 13, so that the handle 12 is prevented from being loosened accidentally and the pull rod 11 and the annular brush 10 are prevented from sliding accidentally, thereby facilitating the normal measurement of the liquid level by the liquid level meter.

[0034] All the technical features in the embodiment can be freely combined according to actual needs.

[0035] The above embodiment is a preferred implementation scheme of the utility model, and in addition to this, other modes of implementation are also included, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
