DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. The examples described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0018] like Figures 1 to 14 As shown, a water filtering device for a railway vehicle freight compartment includes a shield 1, a guide filter plate frame 2 and a filter plate 3. The shield 1 is arranged outside the guide filter plate frame 2 and the filter plate 3. The shield 1 is connected to a side column 6 fixed on a compartment side wall panel 5 through a support seat 4. The guide filter plate frame 2 is arranged on the outside of a guide hole 7 processed on the side wall panel 5, and the filter plate 3 is fixed by the guide filter plate frame 2.

[0019] The shield 1 is composed of a panel 11, a shield upright plate 12, a bottom plate 13 and a cover plate 14 to form a shield body. The upper part of the shield upright plate 12 near the support seat 4 is processed with a pin hole 15 and a plurality of limit holes 16. An axially movable pin 41 is arranged in the pin hole on the support seat 4. The pin 41 cooperates with the limit hole 16 to fix the opening and closing angle of the shield 1. The pin hole 15 of the shield upright plate and the pin hole below the support seat 4 are hinged by a first round pin 42.

[0020] A spring 43 and a U-shaped stopper 44 are provided on the latch 41 . The U-shaped stopper 44 is fixed at the middle of the latch 41 . The spring 43 is sleeved on the latch 41 and provided between the support seat 4 and the U-shaped stopper 44 .

[0021] A groove plate 17 is arranged inside the bottom plate 13 of the shield 1. The groove plate 17 and the bottom plate 13 form a drainage sedimentation trough 18. The drainage sedimentation trough 18 can collect the particulate matter in the accumulated water during the diversion process.

[0022] A sediment indicator device is arranged between the slot plate 17 and the bottom plate 13, and the sediment indicator device includes a pointer 81, a rotating plate 82, a rotating arm 83, a pressing plate 84 and a supporting plate 85. The bottom plate 13 of the shield is provided with rotating plates 82 on both sides, and the supporting plate 85 is arranged above the two rotating plates 82. The two rotating plates 82 are respectively hinged with the bottom plate 13 of the shield through a rotating seat, and one end of the rotating shaft of the two rotating plates 82 is respectively connected to the rotating arm 83 near the outside of the slot plate 17, and the other end of the rotating shaft of the two rotating plates 82 is respectively connected to the pointer 81 near the outside of the panel 11. Long grooves 86 are arranged at both ends of the pressing plate 84, and the two rotating arms 83 are respectively connected to the long grooves 86 on both sides of the pressing plate 84 through rod heads 87 fixed on the rotating arms 83. Pointer stops 88 are arranged at the upper and lower limit positions of the pointer 81 on the panel 11 of the shield.

[0023] A locking ear 18 is provided at the lower portion of the shield upright plate 12 , and the locking ear 18 matches with a locking seat 61 provided on the side column 6 and can be locked by a second round pin 62 . A water filter hole 19 is processed at the lower portion of the panel 11 .

[0024] The guide filter plate frame 2 includes a filter plate frame upright plate 21, a sloped baffle 22, a guide plate 23, a baffle seat 24 and a baffle bar 25. The sloped baffle 22 is fixed obliquely upward outside the oblong guide hole 51 processed on the side wall plate 5, and the guide plate 23 is fixed to the lower part of the sloped baffle 22. The filter plate frame upright plate 21 is fixed on both sides of the sloped baffle 22 and the guide plate 23. The filter plate frame upright plate 21, the sloped baffle 22, and the guide plate 23 are fixed to each other to form an integral guide space. The baffle seat 24 and the baffle bar 25 are fixed on the filter plate frame upright plate 21. The first filter plate 31 and the second filter plate 32 are respectively fixed between the sloped baffle 22 and the baffle seat 24, and between the baffle seat 24 and the baffle bar 25.

[0025] After the vehicle is loaded, the drainage path of the accumulated water in the vehicle is as follows: Fig.15As shown, the water is discharged out of the vehicle through the guide hole 7 on the side wall panel 5 of the vehicle, the inclined baffle 22, the first filter plate 31, the second filter plate 32, the guide plate 23, and the filter hole 19 on the panel 11. Among them, the three structures of the upward inclined baffle 22, the first filter plate 31 with holes, the second filter plate 32, and the filter hole 19 of the panel 11 play a blocking role for the bulk cargo in the water, reducing leakage during transportation. The guide plate 23 extends into the inside of the shield 1 to ensure that water and bulk cargo flow into the shield 1. A certain distance is left between the lowest point of the filter hole 19 of the panel 11 and the bottom plate 13. While draining water, the fine bulk cargo flowing in here is deposited and preserved to prevent leakage outside the vehicle.

[0026] When the vehicle is running, the pin 41 in the support seat 4 moves inwardly under the elastic force of the spring 43 and is inserted into the uppermost limit hole 16 of the shield vertical plate 12. At the same time, the U-shaped gear lever 44 in the middle of the pin 41 is located at the bottom under the action of gravity. At this time, the pin 41 cannot move outward to disengage from the upper limit hole 16 of the shield vertical plate 12, thereby realizing the locked limit state of the shield 1.

[0027] During inspection and maintenance, the latch 41 needs to be rotated 180 degrees upward and then pushed outward to overcome the elastic force of the spring 43 to disengage the upper limit hole 16 of the shield vertical plate 12. At this time, the shield 1 can be flipped upward, and after the latch 41 is inserted into the corresponding limit hole 16, the shield can be locked at the opening angles of 90°, 135° and 180°, which is convenient for personnel to maintain and clean.

[0028] The sediment indicator device is set under the shield 1. When the fine bulk cargo gradually deposits on the support plate 85 under the shield 1, and the weight of the sediment plus the support plate 85 is greater than the deadweight of the pressure plate 84, the sediment presses the support plate 85 downward, and the support plate 85 presses the rotating plate 82 downward and drives the rotating arm 83 and the pointer 81 to gradually rotate until the pointer 81 contacts the stopper 88 under the panel 11. At this time, the sediment needs to be cleaned up as soon as possible; when the sediment is cleaned up, the pressure plate 84 moves downward under the action of gravity, driving the rotating plate 82 to rotate in the opposite direction, and the support plate 85 is lifted up until the pointer 81 contacts the stopper 88 above the panel 11. At this time, the indicator device is reset. Based on this, the operator can judge the amount of sediment deposited in the shield 1 by observing the position of the pointer 81.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
