Abstract
The utility model belongs to the technical field of vehicles and provides a warning device of a suction sewage truck. The warning device of the suction sewage truck comprises a liquid level sensor, wherein the liquid level sensor is arranged inside a sewage tank of the suction sewage truck and used for perceiving the height of a liquid level inside the sewage tank. The liquid level is in electric connection with an electronic control unit. The electronic control unit is in electric connection an audible and visual alarm and a vacuum pumping device arranged on the sewage tank. An air inlet of the sewage tank is provided with a stop valve controlled by an electromagnetic valve. The electromagnetic valve is in electric connection with the electronic control unit. When the liquid level inside the sewage tank reaches a certain height, the liquid level sensor can stimulate the electronic control unit, and the electronic control can control the vacuum pumping device to stop working to protect the vacuum pumping device. Meanwhile, an alarm can be given by the audible and visual alarm, and warning effects are achieved. The electronic control unit can control the electromagnetic valve to open the stop valve. Air outside enters into the sewage tank, and negative pressure inside the sewage tank can not fall any more. Damage of the vacuum pumping device is avoided to enable the vacuum pumping device safer.
Description
Technical field
The utility model belongs to the special-purpose vehicle technical field, relates in particular to a kind of suction-type sewer scavenger warning device.
Background technology
Suction-type sewer scavenger is collection, transfer cleaning transportation mud, sewage, avoids the Novel environmental-sanitation vehicle of secondary pollution; But the suction-type sewer scavenger self-suction discharge, operating rate is fast, and capacity is large, and convenient transportation is applicable to collect the liquid substances such as transportation ight soil, mud.
Suction-type sewer scavenger will be inhaled into vacuum by vacuum extractor in the Water Tank, under the atmospheric effect in the external world, sewage is entered in the tank, can be drawn in the vacuum extractor when sewage is too much in the tank, cause the damage of vacuum extractor, therefore suction-type sewer scavenger is provided with an anti-overflow valve, anti-overflow valve be one with the check valve apparatus of float, be contained in place, large tank top, join with the vacuum extractor air entry, its effect is when the fast canful of soil pick-up, because the effect of float is with the air entry of retaining valve top to vacuum extractor, under the acting in conjunction of float and pull of vacuum, close air entry, can prevent effectively that sewage and the dirt in the tank is drawn in the vacuum extractor, cause the damage of vacuum extractor; But when anti-overflow valve is inoperative, the sewage in the tank will be drawn in the vacuum extractor, vacuum extractor is damaged.
The utility model content
Technical problem to be solved in the utility model is: a kind of suction-type sewer scavenger warning device is provided, is intended to solve the anti-overflow valve of suction-type sewer scavenger when inoperative, sewage is drawn in the vacuum extractor, the problem that vacuum extractor is damaged.
For solving the problems of the technologies described above, the technical solution of the utility model is: the suction-type sewer scavenger warning device that the utility model provides, comprise the liquid level sensor that is used for liquid level in the described Water Tank of perception in the Water Tank that is arranged at described suction-type sewer scavenger, described liquid level sensor is electrically connected ECU (Electrical Control Unit), and described ECU (Electrical Control Unit) is electrically connected an audible-visual annunciator and the vacuum extractor that is positioned on the described Water Tank.
As a kind of improvement, the air intake opening of described Water Tank is provided with the stop valve by solenoid control, and described solenoid valve is electrically connected described ECU (Electrical Control Unit).
As a kind of improvement, described stop valve is connected with retaining valve away from an end of described Water Tank.
As a kind of improvement, described liquid level sensor is the liquid level feeler lever, and described liquid level feeler lever is arranged on the top of Water Tank.
After having adopted technique scheme, the beneficial effects of the utility model are:
Owing to having designed liquid level sensor and audible-visual annunciator, when the sewage tank level reach a certain height, liquid level sensor passes to ECU (Electrical Control Unit) with signal; ECU (Electrical Control Unit) can be controlled vacuum extractor and quit work; the protection vacuum extractor, audible-visual annunciator will be reported to the police simultaneously, plays warning function.
Because the air intake opening of Water Tank is provided with the stop valve by solenoid control, when the sewage tank level reach a certain height, ECU (Electrical Control Unit) can be controlled solenoid valve and open stop valve, outside air enters in the Water Tank, the interior negative pressure of tank is no longer descended, avoided the damage of vacuum extractor, made vacuum extractor safer.
Because liquid level sensor is the liquid level feeler lever, the liquid level feeler lever is arranged on the top of Water Tank, has avoided the liquid level feeler lever because contact sewage wears out and demagnetization, also makes things convenient for the daily maintenance of warning device and maintenance.
