Abstract
The utility model discloses a liquid level alarm system for a gutter, which comprises detection electrodes placed in the gutter; the detection electrodes are connected with a liquid level sensor; and the liquid level sensor is connected with an alarm device and a power supply respectively. Firstly, the position is selected in the gutter, and the measurement part is mounted; as the water in the gutter is bad, all connection points are tinned to avoid the effect on the resistance value of an alarm sensor; a support frame is specially made by a PVC (Polyvinyl Chloride) wire chase and vertically fixed in the gutter; and the detection electrodes are uniformly placed in the gutter so as to avoid the disturbance caused by the water on the surface to the liquid level sensor. In order to enable an operator in charge to directly observe the liquid level height of the gutter, an audible and visual alarm is directly fed back to a duty room. The liquid level alarm system can control the liquid level of the gutter, eliminate the environment pollution caused by the water discharge and reduce the labor intensity of staff.
Description
Technical field
The utility model relates to a kind of pit alert system, especially a kind of trench pit alert system.
Background technology
At present, run into Sometimes When It Rains, surpass warning line if can not in time find the liquid level in the trench, thereby cause wastewater disposition to pollute to environment, though the staff observes the trench liquid level incessantly, if operator on duty's working sense of responsibility is not strong, the image that situations such as sewage outflow directly influence enterprise appears unavoidably.
The utility model content
For remedying the deficiencies in the prior art, the utility model provides a kind of installation simple, has the trench pit alert system of warning function.
For achieving the above object, the utility model adopts following technical scheme: the trench pit alert system, and it comprises the exploring electrode of putting into trench, and exploring electrode is connected with liquid level sensor, and liquid level sensor is connected with power supply with warning device respectively.
At first, in trench, choose the position, install and measure part, because water quality inferiority in the trench has carried out warding off tin in order to avoid influence warning sensing resistor resistance to each contact, with support of the special making of PVC wire casing, be vertically fixed in the ditch, exploring electrode is put into ditch uniformly, avoided the interference of surface water quality the level sensing part.In order to make the operator on duty can see the trench liquid level intuitively, sound and light alarm is directly fed back in the duty room.
Beneficial effect: the utility model is the ditch liquid level controllably, stops to occur water and effluxes and cause environmental pollution, alleviates staff labor intensity, and advantage is as follows: 1, antijamming capability is strong, installs simply, need not debugging, Maintenance free; 2, have the height of high water stage, low-water level, limit low-water level and water level, sound and light alarm is arranged; 3, has limit low-water level warning function; 4, having water level shows; 5, has the noise reduction auto restore facility.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 circuit diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the trench pit alert system, it comprises the exploring electrode of putting into trench, and exploring electrode is connected with liquid level sensor, and liquid level sensor is connected with power supply with warning device respectively.As shown in Figure 2, (COM) terminal of exploring electrode connects the common port of liquid level sensor, and number binding post is corresponding in (1,2,3,4,5,6,7,8) of (1,2,3,4,5,6,7,8) number terminal and liquid level sensor joins; (9), (10) number connection terminal is normally opened contact, can external signalling alarm equipment; (11), (12) are power supply terminal; (13), (14) external ann silence; (15), (16) terminal is external normally closed test, (17), (18) terminal are external normally closed test, are used for the test of warning device.When needs are made regular check on the duty of system, pin the test button, warning system is carried out self check, and sends alerting signal.At this moment, show that instrument is in normal duty.Otherwise, please in time overhaul, try to avert accidents.
