Specific embodiment

Understand to make the objectives, technical solutions, and advantages of the present invention clearer, it is right below with reference to embodiment and attached drawing The present invention is described in further details.

It is shown in Figure 1: it is provided by the invention can remote water supply fire fighting truck, including fire fighting truck ontology 1, the fire fighting truck Ontology 1 is equipped with waterway structure 2, automatic deploying and retracting water band device 3, winding belt guiding device 4 and foldable ladder 5.

Shown in Figure 2: a kind of waterway structure 2 provided by the invention, including water pump 201, the water pump 201 go out moisture For two-way, therein to connect all the way with cleaning water tank 202, another way is connect with fire hose (not shown)；With water pump 201 The inlet pipeline that is connected of water inlet be divided into A, B two-way, inlet pipeline A 204 therein includes check-valves A 205, discharge water ball Valve A 206 and vacuum pump 207, check-valves A 205 are located at the water inlet of inlet pipeline A 204, and vacuum pump 207 is located at water pump 201 water inlet, water drain ball valve A 206 are located on the pipeline between check-valves A 205 and vacuum pump 207；Water inlet pipe therein Road B 208 includes automatic backwashing filter 209, check-valves B 210 and the butterfly valve 211 being sequentially connected in series, automatic back flush filtration Device 209 is located at the water inlet of inlet pipeline B 208, and butterfly valve 211 is located at the water inlet of water pump 201；It is washed in automatic backflushing The water inlet of filter 209 is equipped with a threeway 212, is separately connected a water inlet branch in two water inlets of the threeway 212 213, check-valves C 214 is equipped in the water inlet of each water inlet branch 213；Appointing between check-valves C 214 and threeway 212 One water inlet branch road is equipped with water drain ball valve C 215；It is equipped in the water inlet of each water inlet branch 213 for connecting floating ship pump 217 quick coupling 216；Flowmeter 218 and electric control valve 219 are equipped on the outlet pipeline connecting with fire hose.? The outlet pipeline connecting with cleaning water tank 202 is equipped with normally-closed ball valve 220, and the cleaning water tank 202 is equipped with water drain ball valve D 221, it is equipped with high pressure cleaning pump 222 in the water outlet of cleaning water tank 202, is equipped with spray in the water outlet of high pressure cleaning pump 222 Component 223 is drenched, the spray assemblies 223 include at least one (2 are shown in figure) spray head 224.

In the case that water quality is bad or water source farther out, open butterfly valve 211, enabling inlet pipeline A 204 is that water pump 201 supplies Water, it may be assumed that make into water after the filtering of automatic backwashing filter 209, flow into water pump 201, flow into stream after the pressurization of water pump 201 Meter 218, electric control valve 219 are needed at water by fire hose supply.

Under this water supply pattern:

It a, can be by the way that arbitrarily water inlet branch or two-way water inlet branch are that automatic backwashing filter 209 provides water inlet all the way；

B, floating ship pump 217 can be connected by quick coupling 216 in the water inlet of each water inlet branch 213 and carries out diversion；

It c, can be according to the use aqueous condition needed at water, by adjusting the revolving speed or electric control valve of water pump, to control out water flow Amount and discharge pressure；

If d, water quality is very poor, there are many impurity filtered, and automatic backwashing filter 209 can exist according to import and outlet Pressure difference, carry out automatic backwash.

2, in the preferable situation of water quality, butterfly valve 211 is closed, enables inlet pipeline B 208 as the water supply of water pump 201, it may be assumed that pass through Vacuum pump 207 introduces water inlet, flows into flowmeter 218, electric control valve 219 after the pressurization of water pump 201, is supplied by fire hose It needs at water.When the inlet pressure of water pump 201 reaches the pressure of the setting of vacuum pump 207, vacuum pump 207 stops working.At this point, It can be according to the use aqueous condition needed at water, by adjusting the revolving speed or electric control valve of water pump, to control water flow and water outlet pressure Power.

3, normally-closed ball valve 220 is opened, can make to be stored into cleaning water tank 202 by the pressurized cleaning water outlet of water pump；When It needs to clean in use, can be the water supply of spray head 224 by high pressure cleaning pump 222.

Join as shown in figure 3 and figure 4: a kind of automatic deploying and retracting water band device 3 provided by the invention, including fixed bracket 301, master Axis 302, bracing ring 303, roller 304, gear mechanism and driving mechanism etc..Fixed bracket 301 is fixed at the both ends of main shaft 302 On, it forms a fixed connection with fixed bracket 301.This, which is fixedly connected, can choose as such mode: in the upper of fixed bracket 301 Two bearing blocks 305 of side interval setting, the both ends of main shaft 302 are connect by round end flat key 306 with bearing block 305.Bearing block 305 It the modes such as can be connected through a screw thread to be fixed on fixed bracket 301, as long as being easily installed main shaft.Bracing ring 303 can turn It is installed on main shaft 302, can specifically be realized by way of bearing dynamicly.Such as it is as shown in the figure, the quantity of bracing ring 303 is Two, two bearings 307 are arranged at intervals on main shaft 302, the outer ring of bearing 307 and bracing ring 303 are fixed, in this manner it is possible to Realize the relative rotation of bracing ring 303 and main shaft 302.Conventional, round nut can be set in the end of bearing 307 and stop Washer etc., to limit its axial movement.304 fixing sleeve of roller be loaded on bracing ring 303 outside, so as to bracing ring 303 1 With rotation, the outside of roller 304 is for winding fire hose.

To prevent fire hose from being skidded off by the side of roller 304, two bracing rings 303 are set to the end of roller 304, often It is respectively and fixedly provided with the disk 308 that diameter is greater than 304 diameter of roller outside a bracing ring 303, can guarantee the winding of fire hose in this way Thickness.

The gear mechanism includes gear 309 and gear ring 310, and gear 309 is fixed on the output of driving mechanism A 311 On axis, gear ring 310 is fixed on bracing ring 303, such as shown in the figure, and gear ring 310 is located in the inner hole of bracing ring 303, gear 309 engage with gear ring 310.In this way, when driving mechanism A 311 works, output shaft rotation, drive of the gear ring 310 in gear 309 Dynamic lower rotation, meanwhile, gear ring 310 drives roller 304 to rotate together, to realize the automatic deploying and retracting of fire hose.

Driving mechanism A 311 can do many selections, can be with for example, can choose as hydraulic motor or motor etc. It is separately provided, the mechanism can also be installed additional in the dynamical system of original fire fighting truck.It, can be with when being selected as independent hydraulic motor By the way that fixed plate 312 is arranged on fixed bracket 301, hydraulic motor 311 is fixed on fixed plate 312 by modes such as bolts On.For convenient for count wound condition, preferably further include the encoder 313 for measuring 310 turnning circle of gear ring.
