Description

Technical Field

[0001] The utility model relates to the technical field of sprinkler truck control, in particular to an intermittent automatic spraying system of a mine sprinkler truck and a mine sprinkler truck. Background Art

[0002] In recent years, with the continuous extension of coal mining, environmental governance and ecological restoration around coal mines have become one of the important tasks of various coal enterprises. Environmental governance in the operating area has become the main focus of current work. Watering and dust reduction is a relatively effective way to reduce dust around the operation. There has always been a problem in the actual operation process: the watering system of the sprinkler truck is mainly composed of high spray, low spray, gravity self-flow, strong internal circulation, high-pressure water cannon and spray, etc. The sprinkler truck mainly uses high-ground spray to continuously sprinkle water and dust reduction when sprinkling water on the ramp and the operating platform. Continuous sprinkling will cause excessive sprinkling of water in some operating areas. When the dump truck of the soil dump is running on the ramp, it will slip and overcurrent, which is easy to cause safety problems of the dump truck and excessive loss of the traction motor of the dump truck. Excessive sprinkling also causes waste of water resources; the appropriate amount of sprinkling at the operating plate and ramp of the soil dump can improve the environment of the coal mine operating area. It is necessary to control the steering wheel with one hand and the switch with the other hand, which poses a great safety hazard to driving. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Figure 1Schematic diagram of an intermittent automatic spraying system for a mining sprinkler truck provided according to an embodiment of the utility model, the system is applied to a mining sprinkler truck. Figure 1 As shown, the system includes: a speed regulating solenoid valve 10, a hydraulic motor 20, a water pump 30 and a time relay 40. The speed regulating solenoid valve 10 is connected to the hydraulic system of the hydraulic motor 20, the hydraulic motor 20 is in transmission connection with the water pump 30, the water pump 30 is connected to the sprinkler head 50, and the intermittent contact of the time relay 40 is connected to the control end of the speed regulating solenoid valve 10.

[0018] Specifically, in the embodiment of the utility model, the time relay 40 is used to control the intermittent on and off of the speed regulating solenoid valve 10;

[0019] The speed regulating solenoid valve 10 is used to control the on and off of the hydraulic system, thereby controlling the start and stop of the hydraulic motor 20;

[0020] The hydraulic motor 20 is used to intermittently drive the water pump 30 to work, thereby driving the sprinkler head 50 to perform intermittent spraying operations in the soil dump.

[0021] Preferably, in the embodiment of the utility model, the model of the time relay 40 includes DH48S-S. Specifically, the DH48S-S time relay is a cyclic delay relay, and the control time is between 0.01s-99h, and the cyclic timing on-off operation can be performed according to the set control time. For example, if the control time is set to 10s, the working process of the DH48S-S time relay is: power on for 10s, then disconnect for 10s, and then power on and off cyclic control.

[0022] Specifically, Figure 1 As shown, a butterfly valve 60 is further provided between the water pump 30 and the sprinkler head 50 for controlling the cut-off and conduction of the sprinkler head 50 .

[0023] The butterfly valve 60 is electrically connected to the butterfly valve switch 70 , wherein the butterfly valve switch 70 is used to control the on-off of the butterfly valve 60 .

[0024] Specifically, Figure 1 As shown, a power supply 80 is also included. The power supply 80 is electrically connected to the butterfly valve switch 70 and is used to supply power to the butterfly valve switch 70.

[0025] Specifically, Figure 1 As shown, a spray switch 90 is also included, which is connected to the control end of the time relay 40 and is used to control the start and stop of the time relay 40.

[0026] Specifically, Figure 1 As shown, the spray switch 90 is also electrically connected to the power source 80 .

[0027] The embodiment of the utility model provides an intermittent automatic spraying system for a mining sprinkler truck, in which the timed on and off of the time relay 40 is used to control the action of the speed regulating solenoid valve 10, and the speed regulating solenoid valve 10 adjusts the oil pressure of the water pump through the oil volume to adjust the working state of the water pump 30, so that the water truck performs intermittent spraying.

[0028] Specifically, when the coil of the time relay 40 is de-energized, the intermittent contacts are in a normally closed state, and the speed control solenoid valve 10 is powered on for a long time to control the hydraulic power system and the water pump 30 to work normally; when the coil of the time relay 40 is energized, the intermittent contacts work, and the hydraulic power system is controlled by controlling the on and off of the speed control solenoid valve 10, so that the hydraulic motor 20 and the water pump 30 work intermittently, thereby realizing intermittent automatic control of spraying during the spraying process, and the intermittent time and the spraying time can be adjusted and work automatically, thereby completing the required time control.

[0029] The intermittent automatic spraying system of a mining sprinkler provided by the embodiment of the utility model has the following technical effects compared with the traditional sprinkler:

[0030] (1) The operation is simpler. After the time is set on the time relay 40, the time relay 40 automatically adjusts. When the time is working, turn on the switch, and the spraying automatically enters the intermittent spraying mode. It is convenient and quick, and can realize intermittent automatic control of watering with good effect.

[0031] (2) Intermittent spraying can be achieved on various road sections. The amount of water sprayed on the ground is uniform and moderate, and the dust reduction effect is obvious.

[0032] (3) Reduce the problem of motor overcurrent damage caused by excessive watering of operating vehicles. Intermittent spraying can be achieved on various road sections, and the amount of water sprayed on the ground is uniform and moderate. When vehicles are driving on such roads, it is not easy for the vehicle to slip due to excessive water, causing the motor to idle and cause motor overcurrent damage.

[0033] (4) Save a lot of water resources and achieve more efficient environmental governance. Intermittent spraying can achieve different degrees of spraying on different road surfaces. The amount of water sprayed on the necessary road surface is moderate, and the degree of dust reduction is improved. When working on special road surfaces such as ramps, the amount of water sprayed is intermittent, and the amount of water is moderate, which can just reduce dust on the road surface without causing excessive water flow, which will damage the soil retaining function.

[0034] (5) Effectively extend the service life of the water pump and electric butterfly valve. In the spraying mode of traditional sprinkler trucks, the water pump is always running, which will cause water pump fatigue, reduce working continuity, and greatly reduce life. The intermittent spraying in the utility model can relieve the working time of the water pump, will not cause water pump fatigue, and increase the continuity of each component of the water pump, thereby effectively extending the life of the water pump.

[0035] In the spraying mode of traditional sprinkler trucks, the electric butterfly valve is constantly impacted by water pressure when it is long open, and the valve core in the middle of the butterfly valve has been deformed by high pressure, causing damage to the butterfly valve. In addition, when it is long open and long closed, the valve core rod is prone to rust and deform, causing damage to the butterfly valve. In the intermittent spraying state of the utility model, the electric butterfly valve is in frequent action, and the water pressure changes with the control of the water pump, causing the impact of the butterfly valve core to weaken, and the valve core rod is not easy to rust and deform when it moves back and forth. This can improve the utilization rate of the electric butterfly valve, and under this protection, the service life can be greatly extended.

[0036] (6) Eliminate the potential safety hazard caused by one-handed steering wheel operation during driving. In the traditional spraying mode, the driver must frequently operate the spraying status. If the driver presses the switch while driving, the driver will have to operate the steering wheel with one hand and drive without paying attention, which is very likely to cause a vehicle accident. The intermittent automatic spraying system for a mining sprinkler truck provided by the embodiment of the utility model is completed on time, so the driver does not have to worry about the amount of water sprayed and can concentrate on driving, thus avoiding vehicle accidents caused by driver misoperation or distraction.

[0037] The embodiment of the utility model further provides a mining sprinkler truck, including the intermittent automatic spraying system of the mining sprinkler truck provided by the embodiment of the utility model.
