Abstract

The invention provides a watering device of an environmental sanitation sprinkler, which comprises a self-suction water pump (5), a first filter (2), a fire-fighting water pipe (4), a hose (6) and a coarse filter (7), wherein one end of the fire-fighting water pipe (4) is connected with a water outlet of the self-suction water pump (5), the other end of the fire-fighting water pipe is connected with a water tank (1) through a ball valve (3) and the first filter (2) in sequence, and a water inlet of the self-suction water pump (4) is connected with the coarse filter (7) through the hose (6). This sanitation watering lorry adds water installation can effectually get rid of the impurity of river or lake water through coarse filter's setting, can ensure to wash can not have impurity entering water pump in, can avoid the water pump to break down because of inhaling impurity, also can ensure that impurity can not get into the water operation system of sanitation watering lorry, and the surface water in the utilization river or the lake that the sanitation watering lorry just can be nearby of being convenient for carries out the water supply.

Description

Water adding device of sanitation sprinkler

Technical Field

The invention relates to a water adding device, in particular to a water adding device applied to an environmental sanitation sprinkler.

Background

The environmental sanitation sprinkler is a road surface sprinkling environmental sanitation device, which is provided with a high-pressure waterway system and mainly washes and sprinkles the road surface by a fan-shaped high-pressure water curtain sprayed by a long-row spray rod during operation. The water supply device is used for supplying water to a water tank of a sanitation sprinkler, the sanitation sprinkler needs to be operated outdoors for a long time, the water supply is used up frequently in the operation process, the nearby places where the water supply can be carried out are rivers or lakes frequently, however, in a water supply path, impurities such as silt in the water source of the rivers or lakes can enter the water tank through the water supply device, and the water spraying operation system of the sanitation sprinkler is blocked.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides a watering device of an environmental sanitation sprinkler, which can effectively avoid bringing impurities into a water tank when a washing and sweeping vehicle supplies a water source by using water in river or lake.

In order to achieve the purpose, the invention provides a water adding device of an environmental sanitation sprinkler, which comprises a self-suction water pump, a first filter, a fire-fighting water pipe, a hose and a coarse filter, wherein one end of the fire-fighting water pipe is connected with a water outlet of the self-suction water pump, the other end of the fire-fighting water pipe is connected with a water tank sequentially through a ball valve and the first filter, and a water inlet of the self-suction water pump is connected with the coarse filter through the hose.

As a further improvement of the invention, the first filter is a water filter with a pollution discharge function, the first filter comprises a controller, a differential pressure transmitter and a driving motor, and the controller is electrically connected with the differential pressure transmitter and the driving motor respectively.

As a further development of the invention, the hose is a transparent wire hose.

As a further development of the invention, the coarse filter is a centrifugal filter.

As a further improvement of the invention, the ball valve is an electric control ball valve.

Compared with the prior art, the water adding device of the environmental sanitation sprinkler can effectively remove impurities in river water or lake water through the arrangement of the coarse filter, can ensure that no impurities enter the water pump during washing, can avoid the water pump from breaking down due to the fact that the impurities are sucked in, and can also ensure that the impurities do not enter a water operation system of the washing and sweeping vehicle; the water filter with the sewage discharge function can ensure the efficiency of water source supply and reduce the maintenance frequency of a filter screen in the filter; by arranging the transparent steel wire hose, the bearing strength of the hose can be ensured, and meanwhile, the water quality can be visually observed; through adopting centrifugal filter, can go out impurity such as grit in the water under the effect of centrifugal force.

Drawings

Fig. 1 is a schematic structural view of the present invention.

In the figure: 1. the water tank, 2, first filter, 3, ball valve, 4, fire hose, 5, from inhaling formula water pump, 6, hose, 7, coarse filter.

Detailed Description

The invention will be further explained with reference to the drawings.

As shown in figure 1, a sanitation watering lorry adds water installation, including from inhaling formula water pump 5, first filter 2, fire water pipe 4, hose 6, coarse filter 7, the one end of fire water pipe 4 is connected with from the delivery port of inhaling formula water pump 5, and the other end loops through ball valve 3, first filter 2 and is connected with water tank 1, the water inlet of inhaling formula water pump 4 passes through hose 6 and is connected with coarse filter 7. The impurity that can effectual get rid of river or lake water through setting up of coarse filter 7 can ensure to wash can not have impurity entering water pump, can avoid the water pump to break down because of inhaling impurity, also can ensure that impurity can not get into the water operation system of sanitation watering lorry.

The first filter 2 is a water filter having a sewage discharge function. Through the setting of water filter, guaranteed the efficiency that the water source supplied with, also reduced the maintenance frequency to filter screen in the filter. When the impurity that its filter screen department held back is more, can produce pressure differential between its business turn over, the export, when pressure differential reaches the setting value, differential pressure transmitter among the water filter passes its inside controller with the signal of telecommunication, the controller can control driving motor and pass through drive assembly drive shaft and rotate, water filter's drain is opened simultaneously, the impurity of holding back is discharged by the drain, after water filter's filter screen washs and finishes, its business turn over, the pressure differential between the export can fall to the minimum, water filter can return to initial filtration form, thereby can normal operating.

The hose 6 is a transparent steel wire hose. Through making hose 6 be transparent wire hose, can guarantee the bearing strength of hose, can carry out the visual observation to quality of water simultaneously.

The coarse filter 7 is a centrifugal filter. Through adopting centrifugal filter, can be under the effect of centrifugal force, go out impurity separation such as grit in the aquatic to can avoid gathering more impurity and influence the efficiency of absorbing water around filter 7, also can avoid impurity to get into in the water operation system of water pump or sanitation watering lorry.

The ball valve 3 is an electric control ball valve. Automatic water supply can be realized by electrically controlling the opening and closing of the ball valve 3.
