Compared with the prior art, the beneficial effects of the utility model are that:

1. the mode that the pH detection device is fixed in the sewage pool in the traditional scheme is changed, the pH detection device is fixed on the floating device, the pH detection device floats on the sewage by utilizing the floating device, and the pH detection device can normally detect no matter how the sewage liquid level changes;

2. be provided with two longitudinal slide rail on two relative walls of effluent water sump, be connected with same flotation device through floatable slider and connection rope, because traction, the restriction of two connection ropes prevent to float the pearl device and depend on effluent water sump corner, liquid mobility in the corner is little, inhomogeneous and lead to the pH value to detect inaccurately, has improved the accuracy that detects.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1, the floating sewage pH alarm device of the present invention comprises a slide rail 1, wherein the slide rail 1 comprises a first slide rail 11 and a second slide rail 12 respectively longitudinally fixed on two opposite side walls 8 (as shown in fig. 2) of a sewage tank, the first slide rail 12 is provided with a slot 101, as shown in fig. 2, a slider 2 is arranged in the slot 101, the slider 2 is fastened in the slot, and the slider 2 can slide up and down in the slot 101; the structure of the second slide rail 12 is consistent with that of the first slide rail 11, and the slide block 2 in the first slide rail 11 and the slide block in the second slide rail 12 are respectively connected with a floating device 4 through a connecting rope 3; the slide block 2 is made of polyethylene foam plastic;

the length of the slide rail 1 is consistent with the depth of the sewage pool, the top of the slide rail is flush with the top surface of the sewage pool, and the bottom of the slide rail is flush with the bottom surface of the sewage pool.

As shown in FIG. 3, the floating device 4 comprises a first plate 41, wherein the first plate 41 is a plastic plate and has a thickness of 0.5-0.8 cm; the lower surface of the first plate 41 is provided with a floating interlayer 43, the floating interlayer 43 is made of foam, so that the floating device 4 can float on the water surface, and the thickness of the floating interlayer 43 is 3-4 cm; a second plate 42 is arranged below the floating device 4, the second plate 42 is a plastic plate, and the thickness of the second plate is 0.5-0.8 cm; the floating device 4 and the slide block 2 can move up and down along with the change of the liquid level;

when the liquid level is lowered, the floating device 4 and the slide block 2 simultaneously descend along with the liquid level; when the liquid level rises, the floating device and the slide block rise along with the liquid level at the same time; for not setting up the slide rail and directly will connecting the reason that the rope is fixed in the wastewater disposal basin edge and have: if the floating device 4 is fixed at the edge of the sewage pool through the connecting line, the connecting rope needs to be longer to ensure that the pH value detection device 5 is in contact with the liquid level when the liquid level is lower, and the positions of the floating device and the fixed connecting line are much shorter relative to the length of the connecting rope when the liquid level rises (the sewage pool is full) under the length of the connecting rope, so that the floating device is attached to the corner of the sewage pool due to the discharge or discharge of sewage, and the detected pH value is inaccurate due to the poor and uneven liquidity of liquid in the corner; therefore, two slide rails are provided to limit the position of the floating device and prevent it from sticking to the corners of the wastewater tank.
