Description

Technical Field

[0001] This application relates to the technical field of sanitation vehicle equipment, and particularly to a water tank for a sanitation vehicle. Background Art

[0002] Sanitation vehicles are special vehicles for municipal street cleaning and tidying. According to their functions in street cleaning, they can be divided into sprinkler trucks and garbage trucks. Among them, the sprinkler truck, also known as a water tanker, has a water tank welded and installed on its vehicle body. It not only has a water gun connected to the water tank through a water pipe and a water pump, but also has sprinkler heads installed under or on both sides of the vehicle body and connected to the water tank, with functions such as spraying water to suppress dust, high and low position spraying for street flushing, flushing and watering guardrails and flower beds, and also has the functions of transporting water and emergency fire fighting.

[0003] When the sanitation vehicle is driving, especially when moving forward in a non-operating state, if the sanitation vehicle travels too fast, when braking, the water in the water tank will impact the front end of the water tank under the action of inertia, and then impact on the vehicle body, affecting the braking process of the vehicle body; even after the brake is fully depressed, under the impact of inertia, the vehicle body of the sanitation vehicle may still slide a certain distance, which may cause traffic accidents such as rear-end collisions.

[0004] Therefore, this application provides a water tank for a sanitation vehicle to solve the problem of inertial impact of the water level in the water tank during the driving process of the sanitation vehicle. Utility Model Content

[0005] The purpose of this application is to solve the problems existing in the prior art, and to propose a water tank for a sanitation vehicle.

[0006] In order to achieve the above purpose, this application adopts the following technical solutions:

[0007] A water tank for a sanitation vehicle includes a box body. A partition plate is welded and fixed along the diagonal of the box body in the length direction. The bottom end and the top end of the partition plate are respectively fixed on the inner bottom wall and the inner top wall of the box body. The partition plate divides the space inside the box body into an upper water storage chamber one and a lower water storage chamber two. The upper end of the water storage chamber one is provided with a filling port and the bottom end is provided with a sewage discharge port. Valves are installed at both the filling port and the sewage discharge port. A plurality of inclined plates are welded and fixed in the water storage chamber two. A number of through holes are evenly distributed on both the partition plate and the plurality of inclined plates.

[0008] Preferably, the interval between two adjacent inclined plates meets the requirement that the top end of the lower adjacent inclined plate is located above the bottom end of the upper adjacent inclined plate.

[0009] Preferably, a vertical mesh plate is provided on the side of the sewage discharge port inside the box body, and the bottom end of the partition plate is fixed on the upper end of the mesh plate.

[0010] Preferably, an air diffuser pipe is laid on the bottom wall of the second water storage chamber. The end of the air diffuser pipe penetrates through the side wall of the second water storage chamber and is connected to an air pipe installed on the outer wall of the box. The other end of the air pipe is connected to a horizontal air diffuser opening, and a pressure regulating valve is provided on the top wall of the box.

[0011] Preferably, an electric heating component is provided in the air pipe.

[0012] Preferably, an air pump is provided between the air pipe and the air diffuser opening.

[0013] Preferably, a filter screen is provided at the port of the air diffuser opening.

[0014] Compared with the prior art, the present application provides a water tank for a sanitation vehicle, which has the following beneficial effects:

[0015] 1. When the sanitation vehicle travels and brakes, the water in the water tank impacts on the partition plate and multiple inclined plates under the action of inertia. The water is divided into multiple layers by the partition plate and the inclined plates, forming multiple regions. This not only reduces the range of water level fluctuation and impact in the box, but also divides the water area, reducing the impact in each area. At the same time, under the action of the inertial impact force of the water, the inclined partition plate and inclined plates are affected, and the force is divided into two directions, namely towards the front end of the box and downward by the inclined plates and the partition plate. The dispersion of the force further alleviates the inertial impact of the water. Thus, the driving safety of the sanitation vehicle is improved.

[0016] 2. In this solution, the partition plate divides the box into the first water storage chamber and the second water storage chamber, and the water pumping ports of each pipeline are arranged in the second water storage chamber. Then, the garbage contained in the pumped water source will be blocked and screened by the partition plate, and effective impurity separation can be carried out. The separated impurities gradually sink near the sewage discharge port along with the decrease of the water level in the box, so that sewage can be discharged from the sewage discharge port. The flexibility of equipment use is improved.

[0017] Other advantages, objectives and features of the present application will be described to some extent in the subsequent description; and to some extent, based on the study of the following text, they will be obvious to those skilled in the art; or, they can be taught from the practice of the present application.

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the attached Figures 1-4 drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0024] Embodiment 1. To solve the problems existing in the prior art, this embodiment provides a water tank for a sanitation vehicle, including a box body 2. A partition board 5 is welded and fixed along the diagonal line in the length direction inside the box body 2. The bottom end and the top end of the partition board 5 are respectively fixed on the inner bottom wall and the top wall of the box body 2. The partition board 5 divides the space inside the box body 2 into the upper first water storage chamber 7 and the lower second water storage chamber 8. The upper end of the first water storage chamber 7 is provided with a water filling port 3, and the bottom end is provided with a sewage discharge port 4. Valves are installed at both the water filling port 3 and the sewage discharge port 4. A plurality of inclined plates 6 are welded and fixed in the second water storage chamber 8, and a number of through holes are evenly distributed on both the partition board 5 and the plurality of inclined plates 6.

[0025] Details of the principle of this implementation:

[0026] A water tank for a sanitation vehicle includes a cylindrical box body 2, and the box body 2 is welded and fixed on the vehicle body 1 of the sanitation vehicle. Along the length direction of the box body 2: the end close to the cab of the sanitation vehicle is the head end, and the other end is the tail end. The top wall of the box body 2 is provided with a water filling port 3 for filling water, and the bottom wall of the box body 2 is provided with a sewage discharge port 4 close to the tail end of the water tank for discharging sewage and sundries. Valves are provided at both the water filling port 3 and the sewage discharge port 4 to control the opening and closing of the water filling port 3 and the sewage discharge port 4.

[0027] A partition board 5 is welded and fixed along the diagonal line in the length direction inside the box body 2. The bottom end of the partition board 5 is welded and fixed on the bottom wall on the side of the sewage discharge port 4 facing the head end of the box body 2; the top end of the partition board 5 is fixed on the inner top wall of the box body 2 close to the head end of the box body 2. Through the partition board 5, the space inside the box body 2 is divided into the upper first water storage chamber 7 and the lower second water storage chamber 8. The water filling port 3 is located on the top wall of the first water storage chamber 7, and the sewage discharge port 4 is located at the bottom end of the first water storage chamber 7. A plurality of inclined plates 6 parallel to the partition board 5 are welded and fixed in the second water storage chamber 8, there are intervals between the inclined plates 6, and a number of through holes are evenly distributed on both the partition board 5 and the plurality of inclined plates 6.

[0028] According to the above technical solution:

[0029] Open the valve of the water inlet 3 and fill the water tank with water through the water pipe until the box body 2 is full. Since the partition plate 5 and the inclined plate 6 are covered with through holes, the setting of the partition plate 5 and the inclined plate 6 does not affect the flow of water filling and storage. At this time, daily street cleaning and water transportation operations can be carried out.

[0030] When the sanitation vehicle brakes while moving forward, the water in the water tank impacts on the partition plate 5 and multiple inclined plates 6 under the action of inertia. The water is divided into multiple layers by the partition plate 5 and the inclined plates 6, forming multiple areas. This not only reduces the range of water level sloshing and impact in the box body 2, but also divides the water area, reducing the impact of each area. At the same time, under the action of the inertial impact force of the water, the inclined partition plate 5 and the inclined plates 6 are tilted, and the force is divided into two directions, towards the front end of the box body 2 and downward, by the inclined plate 6 and the partition plate 5. The dispersion of the force further alleviates the inertial impact of the water. Thus, the driving safety of the sanitation vehicle is improved.

[0031] In addition, in this embodiment, municipal street cleaning not only exists in the streets of big cities, but also in county towns and even some rural areas, there are sanitation vehicles for cleaning. In these areas, however, fire hydrants and other water replenishing devices are not everywhere visible on the streets. When the water in the box body 2 is insufficient, water may be directly pumped from nearby rivers, lakes, and puddles. Such water is mixed with too much debris and garbage, and directly filling it into the box body 2 may cause pipeline blockage. In the design of the partition plate 5 in this solution, the box body 2 is divided into the first water storage chamber 7 and the second water storage chamber 8, and the water intake ports of all pipelines are arranged in the second water storage chamber 8. Then the garbage contained in the pumped water source will be blocked and screened by the partition plate 5, and effective impurity separation can be carried out. The separated impurities sink along the partition plate 5 gradually near the sewage outlet 4 as the water level in the box body 2 drops, so that sewage can be discharged from the sewage outlet 4. The flexibility of equipment use is improved.

[0032] Embodiment 2, in a further embodiment of this solution, the inclination angle of the inclined plate 6 and the interval between two adjacent inclined plates 6 meet the following: the top end of the adjacent inclined plate 6 below is located above the bottom end of the adjacent inclined plate 6 above. This avoids too small an interval and too low a slope, so that the acting force dispersed by the inclined plate 6 is too small to affect the utility of dispersing the inertial impact of water.

[0033] Embodiment 3, in a further embodiment of this solution, a vertical net plate is provided on the side of the box body 2 near the sewage outlet 4, and the bottom end of the partition plate 5 is fixed to the upper end of the net plate. This increases the vertical gathering and stacking space for debris, facilitating sewage discharge.

[0034] Embodiment 4. In a further embodiment of the present solution, in cold weather, the water in the box body 2 is likely to freeze, affecting the progress of the cleaning operation. Therefore, in this embodiment, an air diffuser pipe 9 is laid on the bottom wall of the second water storage chamber 8. A number of air diffuser holes are evenly distributed on the side wall of the air diffuser pipe 9. The end of the air diffuser pipe 9 penetrates through the side wall of the second water storage chamber 8 and is connected to an air pipe installed on the outer wall of the box body 2. The other end of the air pipe is connected to a horizontal air diffuser port 11, which is higher than the cab and faces the traveling direction of the sanitation vehicle. A pressure regulating valve 12 is provided on the top wall of the box body 2.

[0035] According to the above technical solution:

[0036] When the sanitation vehicle is traveling, the wind pours into the air pipe from the air diffuser port 11, and then enters the air diffuser pipe 9 along the air pipe, thereby forming bubbles in the box body 2. The bubbles are used to vibrate the water in the box body 2 to prevent the liquid from freezing. When the air pressure in the box body 2 increases to a certain extent, the pressure regulating valve 12 opens to exhaust air outward.

[0037] Embodiment 5. In a further embodiment of the present solution, an electric heating component 13 is provided in the air pipe. The electric heating component 13 is an electric heating wire. The installation position of the electric heating component 13 is higher than the top wall of the box body 2 to avoid direct contact with the electric heating component 13 due to too high water level. The cold air poured in is heated into hot air by the electric heating component 13 to improve the anti-freezing effect.

[0038] Embodiment 6. In a further embodiment of the present solution, when the wind force is small and cannot pour into the air diffuser pipe 9 against the water pressure, in this embodiment, an air pump 10 is provided between the air pipe and the air diffuser port 11. The air pump 10 is also located above the top wall of the box body 2. The outside air is pumped in by the air pump 10 to ensure that gas can be poured in to form bubbles and stir the water.

[0039] Embodiment 7. In a further embodiment of the present solution, a filter screen is provided at the port of the air diffuser port 11. The air is filtered through the filter screen to avoid impurities such as dust or floating leaves in the poured air.

Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and the application concept of the present application, makes equivalent replacements or changes, and should be covered within the protection scope of the present application.
