Description

Technical Field

[0001] This utility model relates to the technical field of water spray devices, specifically a dust suppression and fire prevention water spray device. Background Technology

[0002] Currently, railway maintenance primarily utilizes self-propelled grinding equipment for tasks such as rail grinding and ballast cleaning. The rapid rotation of the grinding wheels on these equipment generates significant amounts of dust during rail grinding and ballast cleaning. If this dust is inhaled by workers during spillage, it poses a serious health hazard. Furthermore, the rapid rotation of the grinding wheels on the rails produces numerous high-temperature sparks. These sparks can easily ignite flammable materials such as dry grass and leaves along the track, potentially leading to fires. Therefore, designing a dust suppression and fire prevention water spray device is essential. Utility Model Content

[0040] See Figure 1 and Figure 2 As shown, this embodiment of the utility model provides a dust suppression and fire prevention water spray device, including a water tank 2 and a water pump 3 installed on a self-propelled railway device 1. At least one side of the self-propelled railway device 1 is provided with a lifting device 6 and a water spray mechanism 5. The lifting device 6 is used to drive the water spray mechanism 5 to rise and fall. The water spray mechanism 5 is used to form water mist on the side of the self-propelled railway device 1, and the water spray mechanism 5 is connected to the water pump 3 and the water tank 2 in sequence via electromagnetic reversing valves 4. Specifically, lifting devices 6 and water spray mechanisms 5 are respectively provided on both sides of the self-propelled railway device 1. Two electromagnetic reversing valves 4 are provided, each connected to the water spray mechanism 5 on both sides of the self-propelled railway device 1. A filter 214 is installed in the pipeline between the water pump 3 and the water tank 2, and a pressure gauge 33 and a safety valve 32 are installed in the pipeline between the water pump 3 and the electromagnetic reversing valves 4. In this embodiment, the electromagnetic reversing valve is a waterproof stainless steel normally closed electromagnetic valve; when power is lost, the water flow is blocked, and when power is restored, the water flow continues. The water supply pipeline is a synthetic rubber tube containing a layer of steel wire braid. The filter is made entirely of stainless steel, with a 60-mesh stainless steel perforated screen. Specifically, the inlet pipe of water tank 2 is equipped with a first ball valve 212, and the outlet pipe of water tank 2 is equipped with a second ball valve 213. The ball valves are medium- and high-pressure stainless steel ball valves, which are simple in structure, highly corrosion-resistant, and easy to operate. The water supply pipe is equipped with an internal discharge safety valve, which is compact, highly accurate, and maintains the pressure of the entire water spray device at a constant value. A stainless steel pressure gauge is installed on the water supply pipe; this gauge is shock-resistant, pressure-resistant, and highly accurate, allowing for direct observation of the pressure value of the entire water spray device and determining whether the device is operating normally.

[0041] See Figure 3 and Figure 4 As shown, the lifting device 6 includes a mounting base 61, a swing arm 63, and a cylinder 62.

In this embodiment, two longitudinal partitions are provided inside the water tank to divide the interior of the water tank into three cavities. The water tank is constructed from welded stainless steel parts. A longitudinal partition separates the tank body, with interconnected round and U-shaped holes on the partition. Four support seats for the water tank are welded to the lower part of the base plate. U-shaped grooves are machined on the lower part of the support seats, allowing connection to the main frame using bolts and high-strength flat washers. A stainless steel suction screw seat is welded to the lower part of the base plate, used to connect the suction and discharge pipes. Three hydraulic gauge mounting seats and one stainless steel screw seat are welded to the side plates. The hydraulic gauge mounting seats are used to install level gauges, and the stainless steel screw seat is used for communication with other water tanks. Four lifting lugs, an air filter mounting seat, and a maintenance seat are welded to the upper part of the top plate. An air filter is installed on the air filter mounting seat, and a rubber sealing gasket and cover are installed on the maintenance seat.

[0045] See Figure 10 and Figure 11As shown, the water pump 3 is mounted on the railway self-propelled equipment 1 via a mounting bracket 31.

In this embodiment, the water pump is a non-self-priming horizontal end-suction multi-stage centrifugal pump equipped with a power frequency motor. The built-in frequency controller ensures continuous control of the pump's speed changes. The rubber plates are in close contact with the pump surface, reducing friction and vibration.

[0046] See Figure 12 and Figure 13 As shown, the electromagnetic reversing valve 4 is installed below the main frame of the railway self-propelled equipment 1 via a mounting bracket 41. The mounting bracket 41 includes a suspension plate 411. The upper end of the suspension plate 411 is connected to the railway self-propelled equipment 1. The lower end of the suspension plate 411 is bent outward to form a bent plate 412 for installing the electromagnetic reversing valve 4. Ribs 413 are provided on the back of the suspension plate 411 and the bent plate 412.

[0047] The working principle of this utility model is as follows:

[0048] When the ball valve at the water tank's suction port is opened, the water pump motor is energized and rotates. The bushing transmits the power of the water pump motor to the water pump. Water from the water tank enters the water pump's suction chamber through the ball valve, filter, safety valve, and water supply pipeline. Under the action of the water pump, the water in the pressure chamber enters the solenoid directional valve. When the solenoid directional valve is energized, pressurized water enters the dust suppression and fire prevention water spray devices on both sides of the railway self-propelled equipment. When the solenoid directional valve is de-energized, no pressurized water enters the dust suppression and fire prevention water spray devices on both sides of the railway self-propelled equipment.
