Description

一种双水箱环卫车加水系统A water filling system for sanitation vehicles with double water tanks

技术领域technical field

本发明涉及一种双水箱环卫车加水系统，属于特种车辆技术领域。The invention relates to a water filling system for a sanitation vehicle with double water tanks, belonging to the technical field of special vehicles.

背景技术Background technique

环卫车等环卫车辆在上路工作前需要将清水箱加满。因整体设计的需要，这些环卫车清水箱采用的是前水箱和后水箱分开布置的双水箱结构，利用一个加水口连通前水箱和后水箱，前后水箱可以同时进水。前水箱和后水箱的内部顶部都设有溢水管，当水加满后，水从溢水管流到水箱外，操作者观察到后关闭消防栓和加水阀门。这种带前后水箱的加水管路存在两个问题，第一是加水工作效率低，因为前后水箱容积不一致，前水箱比后水箱小，而消防水的流量比较大，前水箱将首先加满并从前水箱溢出，操作者需要先关闭消防栓，让前水箱的水通过加水管慢慢回流到后水箱，前后水箱的水位保持基本一致后再继续打开消防栓加水。继续加水时仍然存在着前水箱先溢出水的问题，需要重复上述操作，直到后水箱也溢出水来才确认水箱加满，整个加水过程需要等待的时间较长，需要反复操作消防栓的关停。第二是增加了用水成本，加水时前后水箱都会有水溢出，且前水箱不止一次溢水，浪费现象较严重。Sanitation vehicles such as sanitation vehicles need to fill up their clean water tanks before going on the road. Due to the needs of the overall design, the fresh water tanks of these sanitation vehicles adopt a double water tank structure in which the front water tank and the rear water tank are arranged separately. A water inlet is used to connect the front water tank and the rear water tank, and the front and rear water tanks can be filled with water at the same time. The interior tops of the front water tank and the rear water tank are all equipped with overflow pipes. When the water is filled up, the water flows from the overflow pipes to the outside of the water tank. After the operator observes, close the fire hydrant and the water filling valve. There are two problems in this kind of water filling pipeline with front and rear water tanks. The first is that the water filling efficiency is low, because the volume of the front and rear water tanks is inconsistent, the front water tank is smaller than the rear water tank, and the flow of fire water is relatively large, the front water tank will be filled first and then When the front water tank overflows, the operator needs to close the fire hydrant first, let the water in the front water tank slowly flow back to the rear water tank through the water filling pipe, keep the water levels of the front and rear water tanks basically the same, and then continue to open the fire hydrant to add water. When you continue to add water, there is still the problem that the front water tank overflows first, and you need to repeat the above operations until the rear water tank also overflows to confirm that the water tank is full. The entire water filling process needs to wait for a long time, and you need to repeatedly operate the shutdown of the fire hydrant . The second is to increase the cost of water use. When water is added, water will overflow from the front and rear water tanks, and the front water tank will overflow more than once, so the waste phenomenon is more serious.

具体实施方式Detailed ways

实施例Example

本实施例的双水箱环卫车加水系统，应用于双水箱环卫车上，双水箱环卫车上内具有前水箱8和后水箱5，后水箱5的容积远大于前水箱8。The water adding system of the double water tank sanitation vehicle of the present embodiment is applied on the double water tank sanitation vehicle. The double water tank sanitation vehicle has a front water tank 8 and a rear water tank 5. The volume of the rear water tank 5 is much larger than that of the front water tank 8.

本实施例的双水箱环卫车加水系统，如图1所示，包括：加水管、第一进水管7、第二进水管4和溢水管11。加水管依次布置有消防接头1、进水过滤器2和进水球阀3。第一进水管7与第二进水管4的一端均与加水管连通，第一进水管7的另一端与前水箱8连通，第二进水管4的另一端与后水箱5连通。第一进水管7上装有气动切断水阀6。前水箱8内装有水位传感器9；当前水箱8内的水位达到水位传感器9的位置时，气动切断水阀6关闭，否则开启。前水箱8上装有出水管10，出水管10与双水箱环卫车的用水设备连接。溢水管11的顶端位于后水箱5内，且靠近后水箱5顶部，其高度与水位传感器9一致，底端连通储水箱12；储水箱12上通过连接管15装有冲洗喷管17；连接管15上安装有冲洗球阀16，冲洗喷管17上具有若干冲洗孔，冲洗孔朝向双水箱环卫车的吸嘴。The water filling system of the sanitation vehicle with double water tanks in this embodiment, as shown in FIG. 1 , includes: a water filling pipe, a first water inlet pipe 7 , a second water inlet pipe 4 and an overflow pipe 11 . The water supply pipe is arranged with a fire-fighting joint 1, a water inlet filter 2 and a water inlet ball valve 3 in sequence. One end of the first water inlet pipe 7 and the second water inlet pipe 4 are all communicated with the water adding pipe, the other end of the first water inlet pipe 7 is communicated with the front water tank 8 , and the other end of the second water inlet pipe 4 is communicated with the rear water tank 5 . Pneumatic shut-off water valve 6 is housed on the first water inlet pipe 7. A water level sensor 9 is housed in the front water tank 8; when the water level in the front water tank 8 reached the position of the water level sensor 9, the pneumatic cut-off water valve 6 was closed, otherwise it was opened. Water outlet pipe 10 is housed on the front water tank 8, and water outlet pipe 10 is connected with the water equipment of double water tank sanitation vehicle. The top of the overflow pipe 11 is located in the rear water tank 5, and near the top of the rear water tank 5, its height is consistent with the water level sensor 9, and the bottom end is connected to the water storage tank 12; the water storage tank 12 is equipped with a flushing nozzle 17 through a connecting pipe 15; Flushing ball valve 16 is installed on 15, has some flushing holes on the flushing spray pipe 17, and flushing hole is towards the suction nozzle of double water tank sanitation vehicle.

第一进水管7连接在前水箱8的底部。第二进水管4连接在后水箱5的底部。出水管10设置在前水箱8的下部。The first water inlet pipe 7 is connected to the bottom of the front water tank 8 . The second water inlet pipe 4 is connected to the bottom of the rear water tank 5 . The water outlet pipe 10 is arranged on the bottom of the front water tank 8 .

为了便于观察储水箱12内的水位，储水箱12为透明塑料材质水箱，其内具有彩色浮球13。For the convenience of observing the water level in the water storage tank 12, the water storage tank 12 is a transparent plastic material water tank with colored floating balls 13 in it.

使用消防栓为双水箱环卫车加水时，打开进水球阀3，打开消防栓，此时前水箱8水位较低，未达到水位传感器9的位置，气动切断水阀6处于开启状态，水通过第一进水管7进入前水箱8，同时通过第二进水管4进入后水箱5。因前水箱8的容积比后水箱5的容积小，水位将率先达到前水箱8中水位传感器9所在位置，触发控制气动切断水阀6气路的电磁阀动作，气动切断水阀6关闭，从而关闭向前水箱8的加水，前水箱8水位不再上升，水继续向后水箱5加注。When using a fire hydrant to add water to the double water tank sanitation vehicle, open the water inlet ball valve 3 and open the fire hydrant. At this time, the water level of the front water tank 8 is low and has not reached the position of the water level sensor 9. The pneumatic cut-off water valve 6 is in the open state, and the water passes through the first A water inlet pipe 7 enters the front water tank 8, and enters the rear water tank 5 through the second water inlet pipe 4 simultaneously. Because the volume of the front water tank 8 is smaller than the volume of the rear water tank 5, the water level will be the first to reach the position of the water level sensor 9 in the front water tank 8, triggering the action of the solenoid valve controlling the air path of the pneumatic water shutoff valve 6, and the pneumatic water shutoff valve 6 is closed, thereby Close the water adding to the front water tank 8, the water level of the front water tank 8 no longer rises, and the water continues to add to the rear water tank 5.

当后水箱5的水位达到溢水管11顶端时，水从溢水管11流出进入储水箱12，储水箱12内部的彩色浮球13位置变动被操作者观察到，操作者可以及时关闭消防栓。或者，操作者也可以选择在加满水之前将冲洗球阀16打开，溢出水将经过连接管15、冲洗球阀16进入冲洗喷管17，冲洗喷管17安装在双水箱环卫车的吸嘴平面的上方，冲洗喷管17内部平行加工有数个锥孔，锥孔的轴线通过冲洗喷管17的圆心，带有压力的溢出水通过个锥孔形成扇形喷洒面喷洒到吸嘴外表面。由于储水箱12水量较少，冲洗喷管17在用光储水箱12内的水之后就无水可喷，直至溢出水再次进入储水箱12，也即意味着后水箱5装满，操作者可以视冲洗状况关闭消防栓。When the water level of the rear water tank 5 reached the top of the overflow pipe 11, water flowed out from the overflow pipe 11 into the water storage tank 12, and the position change of the colored floating ball 13 inside the water storage tank 12 was observed by the operator, and the operator can close the fire hydrant in time. Or the operator can also choose to open the flushing ball valve 16 before filling up the water, and the overflow water will enter the flushing nozzle 17 through the connecting pipe 15 and the flushing ball valve 16, and the flushing nozzle 17 is installed on the suction nozzle plane of the double water tank sanitation vehicle. Above, the inside of the flushing nozzle 17 is processed in parallel with several taper holes, the axis of the taper holes passes through the center of the flushing nozzle 17, and the overflow water with pressure forms a fan-shaped spray surface through the taper holes and sprays to the outer surface of the suction nozzle. Because the water storage tank 12 has less water, the flushing nozzle 17 has no water to spray after using up the water in the water storage tank 12 until the overflow water enters the water storage tank 12 again, which means that the rear water tank 5 is full, and the operator can Close the fire hydrant according to the flushing condition.

加水结束后，气动切断水阀6处于关闭状态，前水箱8和后水箱5未成连通状态，洗扫作业开始后，水从出水管10流出供车内用水设备使用，随着前水箱8的水位下降，低于水位传感器9时，气动切断水阀6打开，前水箱8和后水箱5呈连通状态，前水箱8和后水箱5的水可以全部从出水管10流出。After adding water, the pneumatic cut-off water valve 6 is in the closed state, and the front water tank 8 and the rear water tank 5 are not connected. Descending, when lower than the water level sensor 9, the pneumatic cut-off water valve 6 is opened, and the front water tank 8 and the rear water tank 5 are connected, and the water in the front water tank 8 and the rear water tank 5 can all flow out from the outlet pipe 10.

储水箱12上还装有水龙头14，储水箱12里储存的水除了可以用于冲洗吸嘴外，通过打开水龙头14进行洗手。Water tap 14 is also housed on the water storage tank 12, and the water stored in water storage tank 12 is except that can be used for flushing suction nozzle, washes one's hands by opening water tap 14.

本实施例通过对前水箱8进水的关停控制和对后水箱5溢出水的再利用，避免了加水时反复关停消防栓，缩短了加水时间，提高了工作效率，也避免了水资源的浪费，节约了使用成本。In this embodiment, through the shutdown control of the water inlet to the front water tank 8 and the reuse of the overflow water from the rear water tank 5, it avoids repeatedly shutting down the fire hydrants when adding water, shortens the time for adding water, improves work efficiency, and avoids water resources. waste, saving the cost of use.

本发明不局限于上述实施例所述的具体技术方案，除上述实施例外，本发明还可以有其他实施方式。凡采用等同替换形成的技术方案，均为本发明要求的保护范围。The present invention is not limited to the specific technical solutions described in the above embodiments. Besides the above embodiments, the present invention can also have other implementation modes.
