Description

Small rainwater cleaning vehicle

technical field

The invention relates to the technical field of rainwater cleaning equipment, in particular to a small rainwater cleaning vehicle.

Background technique

As the global climate shows an unstable trend, the frequency of extreme weather is getting higher and higher. Heavy rainfall caused by strong convective weather often leads to excessive precipitation in local areas. In cities, this phenomenon usually causes urban waterlogging. The objective reasons for urban waterlogging are high rainfall intensity, concentrated rainfall areas, and low terrain within the city limits.

The solution to urban waterlogging today is mainly from the following two perspectives: one is to drain rainwater around through drainage facilities; the other is to collect rainwater through water storage facilities. The former requires a large number of underground drainage lines as a network for dredging and guiding, and scatters around the city with the city as the center, but it is necessary to ensure the smoothness of each key drainage node pipeline to ensure the smooth drainage of rainwater. If a blockage occurs in one place It is easy to cause poor excretion of local or even the whole system. The latter is mainly based on the construction of reservoirs, storage lakes and green spaces that are conducive to rainwater infiltration. The water balance is maintained by collecting and reusing rainwater, but it will occupy too much urban construction land, affecting the Economic construction, and even for some old cities, there is no reusable construction space. The common problem of the two is that the drainage facilities are too fixed, limited by the spatial distribution, and cannot be flexible.

In the specific implementation, as shown in Figure 1-Figure 8, the vehicle adopts the traditional trolley mechanism, the body shape is compact, the function is intensive, the load is limited to one person, and the floor area is small. It consists of the following four parts.

(1) Cab. Including powertrain and operating system. The power system adopts the 1.0L displacement engine widely used in mini cars on the market, with sufficient power (power is 45KW) and low fuel consumption (fuel consumption is 7.4L/100km). control.

(2) Transmission system. It is mainly composed of two parts: conveyor track roller and hydraulic rotation control shaft. A row of rollers with a diameter of 100mm is placed on the body plate along the longitudinal direction of the vehicle, and a layer of steel conveyor tracks is laid on it. The entire conveyor device is simple and convenient, and can quickly haul and load and unload the water storage tank, and the steel transmission is realized by the rotation of the rollers. The crawler is rotated, in which the rotation of the roller adopts a well-known technology, which will not be described in detail here; the hydraulic rotation control shaft is fixed on the conveying crawler and is connected with the platform on which the water storage tank is placed.

(4) Pumping system. A cylindrical water tank with a capacity of 282.6L is placed on the platform, which can maximize the collection and storage of accumulated water, and at the same time, it is convenient for loading and unloading tools to quickly load and unload the water storage tank. When moving below the water surface, turn on the switch of the water pump, and then continuously pump the water from the ground, saving operation time.

The driver can control the direction of the vehicle through the steering wheel in the car. It is equipped with a 1.0L displacement engine, and is equipped with manual gear control. The clutch, brake and accelerator pedals are installed under the feet. These devices are connected with the Mecanum wheel of the base through the linkage rod. In this way, the movement and stationary, forward and reverse of the vehicle are realized. This omnidirectional movement method is based on the principle of a central wheel with many axles located around the wheel. These angled peripheral axles turn a part of the wheel. The force is converted to a wheel normal force. Depending on the direction and speed of the respective wheels, the final combination of these forces produces a resultant force vector in any desired direction thereby ensuring that the platform can move freely in the direction of the final resultant force vector without changing the direction of the wheels themselves. . There are many small rollers obliquely distributed on its rim, so the wheel can slide laterally. The busbar of the small roller is very special. When the wheel rotates around the fixed wheel spindle, the envelope of each small roller is a cylindrical surface, so the wheel can roll forward continuously. The Mecanum wheel is compact in structure and flexible in movement, and is a very successful all-round wheel.

The omnidirectional motion equipment based on the Mecanum wheel technology can realize the motion modes such as forward movement, lateral movement, oblique movement, rotation and combinations thereof. The omnidirectional transportation platform developed on this basis is very suitable for the environment with limited transshipment space and narrow working channel, and can realize omnidirectional mobile function more flexibly and conveniently. In this way, the free movement of the vehicle within the space is guaranteed.

When the vehicle is in working state, the driver can operate the operating system. The system is equipped with switches that control the conveying roller, the rotating shaft and the water pump respectively, and is connected to the battery through the power distribution system, which can ensure that the three devices work independently without affecting each other. When the button that controls the "transmission roller" is toggled, the transmission roller drives the hydraulic rotation control shaft on the crawler to move, that is, it stops immediately after closing. When the rotation axis moves to the end of the car, the transmission roller stops automatically. The "rotation axis" is controlled by two buttons, one button is used to control the rotation, which can be rotated clockwise or counterclockwise. Rotation in the range of °; another button is used to control the expansion and contraction of the height of the rotating shaft, and the rotating shaft can be raised and lowered. When the button that controls the "water pump" is toggled to start pumping water into the water tank, when the water tank is full, the water pump will automatically stop working.
