Detailed Description

Referring to fig. 1 to 2, the utility model provides an alpine EMUs anti-overflow water purification tank, including water purification tank body 1, water tank cap 2, water injection pipe 3, water injection pipe 4, sealing plug 5, overflow pipe 6, it is separated with the board to use between two water injection pipe delivery ports,

water injection pipe

3, 4 tops of water injection pipe set up sealing plug 5. The sealing plug 5 comprises a sealing plate 7 with the diameter the same as that of the

water injection pipes

3 and 4, the lower side of the sealing plate 7 is fixedly connected with a positioning assembly, and the positioning assembly is symmetrically arranged along the vertical axis of the sealing plate.

The first embodiment of the positioning assembly is a conical positioning assembly, the conical positioning assembly is formed by splicing two same V-shaped assemblies to form a groove at the upper side of a middle position point 10 of a V-shaped plate 9, a groove at the lower side of a middle position point 10 of a V-shaped plate 8 and two V-shaped plates in a crossed clamping mode. The toper locating component with closing plate 7 hookup location process out with

water injection pipe

3 and 4 inner wall complex straight flange prevents that the closing plate from deviating to one side or slope, sealed water injection pipe upper mouth that can be fine, straight flange and the adjacent hypotenuse of downside adopt the fillet transition, block when preventing the locating component whereabouts, whereabouts smoothly.

The second embodiment of the positioning assembly is three cylinders which are arranged in a circumferential mode, the outermost sides of the three cylinders are located on the same circumference which is concentric with the sealing plate, the outer sides of the three cylinders are matched with the inner wall of the water injection pipe to position the sealing plate, and a water flow channel is reserved between the three cylinders.

The third embodiment of the positioning assembly is two parallel trapezoidal plates which are symmetrically arranged relative to the circle center, straight edges matched with the inner wall of the water injection pipe are machined at the connecting positions of the trapezoidal plates and the sealing plates, the sealing plates are prevented from deviating to one side or inclining, the upper opening of the water injection pipe can be well sealed, the straight edges and the inclined edges adjacent to the lower side of the straight edges adopt fillet transition, and the positioning assembly is prevented from being clamped and smoothly falling when falling.

The maximum outer contour size of the upper part of the positioning assembly is slightly smaller than the inner diameters of the

water injection pipes

3 and 4, the sealing plug 5 is guaranteed to smoothly fall down when falling down, the top of the water injection pipe is completely covered, and the height of the sealing plug 5 is larger than the distance between the upper end face of the water injection pipe and a water tank cap. The weight of the sealing plug 5 is controlled moderately, so that the sealing plug 5 at the upper part of the water injection pipe can float when water is injected, and the water can fall and cover the top of the water injection pipe under the action of the weight after the water injection is stopped.

When the water injection pipe 3 water injection from one side is followed to the water purification case, sealing plug 5 floats under the pressure effect of water injection, and water gets into in the box 1, and sealing plug 5 on the opposite side water injection pipe 4 covers at water injection pipe 4 top under the effect of gravity, avoids the water in the water tank to overflow from water injection pipe 4 after full, can only flow outside the car from overflow pipe 6 of water tank after the water tank is full. When the water injection pipe 4 of the other side of the water purification tank 1 is filled with water, the sealing plug 5 on the water injection pipe 3 covers the water injection pipe 3, and the function of preventing the water injection pipe 3 from overflowing is achieved. Through the overflow of the water injection pipe at the other side when preventing the water injection of the water injection pipe at one side, the water injection port inspection door is prevented from being frozen and the overflowing water is prevented from spilling out of the vehicle, so that the next water injection can be smoothly carried out, and the cleaning work on the ground is reduced.
