Description

Technical Field

[0001] The utility model relates to the technical field of power output of a water pump for a sanitation vehicle, and in particular to a power control component for a water pump for an electric sanitation vehicle. Background Art

[0002] At present, sanitation vehicles are widely used for road cleaning. Sanitation vehicles have water storage and flushing functions and can carry out long-distance road cleaning. Sanitation vehicles switch between low-pressure water pumps and high-pressure water pumps for different environments and sanitary conditions. Therefore, it is necessary to ensure that the high and low-pressure water pump motors have good output power to ensure the cleaning effect and efficiency.

[0003] In the related art, there are three main types of high and low pressure water pump power systems commonly used in electric sanitation vehicles. The first type is that the low pressure water pump is driven by the chassis travel motor through the power take-off, and the high pressure water pump is driven by a separate motor. Therefore, when the vehicle performs low pressure washing operations, it is affected by the chassis speed and the operation effect is poor. The second type of low pressure water pump is also driven by an independent motor, but the cost is greatly increased by adding a motor electronic control system. There is also a type in which the low pressure water pump and the high pressure water pump are driven by one motor, and the motor drives the two water pumps separately through a transfer case or a pulley drive, but the two water pumps require a high power motor to ensure their power output, and the high and low pressure waterways of the sanitation vehicle basically do not work at the same time. When the low pressure water pump is used, the motor still runs at high power, which results in a waste of power. Utility Model Content

[0004] The purpose of the utility model is to provide a power control assembly for a water pump of an electric sanitation vehicle, so as to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A power control assembly for a water pump of an electric sanitation vehicle, comprising:

[0007] A vehicle controller, wherein the vehicle controller is connected to a motor controller and a high-voltage distribution box;

[0012] The power control assembly for the water pump of the electric sanitation vehicle according to this solution has at least the following technical effects:

[0013] The power control component for the electric sanitation vehicle water pump is provided with a high-voltage distribution box between the motor controller and the high-pressure and low-pressure water pump motors, so that the power output of the high-pressure and low-pressure water pump motors are controlled by the high-voltage distribution box respectively, as well as the circuit connection and disconnection of the two. Compared with the traditional sanitation vehicle power system, the power output of the high-pressure and low-pressure water pump motors is controlled by two controllers respectively, thereby reducing the production cost; or when the high-pressure and low-pressure water pump motors are controlled by a high-power motor controller respectively, when the low-pressure water pump is used, the motor controller also operates at high power to avoid energy waste. The power control component can control the power output of the high-pressure water pump motor and the low-pressure water pump motor respectively, thereby reducing the production cost, while saving energy and protecting the environment, avoiding energy waste, and achieving the effect of energy saving and emission reduction.

[0014] In addition, the design of integrating the high-voltage distribution box simplifies the management and maintenance of the power control components, reduces the number and complexity of parts, and improves the stability and reliability of the power control components of the sanitation vehicle.

[0015] As a further solution of the utility model: the vehicle controller is provided with 6 groups of output control terminals.

[0016] As a further solution of the utility model: 6 groups of relays are arranged in the high-voltage distribution box, one end of the 6 groups of relays are respectively connected to the 6 groups of output control ends, and the other ends of the 6 groups of relays are respectively connected to the three-phase line circuit of the low-pressure water pump motor and the three-phase line circuit of the high-pressure water pump motor.

[0017] By connecting one end of the six groups of relays to the six groups of output control ends respectively, and connecting the other ends of the six groups of relays to the three-phase line circuit of the low-pressure water pump motor and the three-phase line circuit of the high-pressure water pump motor respectively, when the low-pressure water pump motor is needed to work, the vehicle controller controls three of the groups of relays through the output control end to energize the three-phase line circuit of the low-pressure water pump motor respectively to control the power output of the low-pressure water pump motor; when the high-pressure water pump motor is needed to work, the vehicle controller controls the other three groups of relays through the output control end to energize the three-phase line circuit of the high-pressure water pump motor respectively to control the power output of the high-pressure water pump motor.
