Detailed Description

The invention will now be further described in the following with reference to the accompanying drawings, in which reference is made to figures 1 to 6, in which embodiments of the invention are shown.

A rain and sewage separating device suitable for an open-air cleaning tank comprises a driving mechanism 100 and a separating mechanism 200. The driving mechanism 100 comprises a pedal 101 and a pull rope 102, the pedal 101 is in a long strip shape, the pedal 101 is arranged in parallel with the cleaning tank 300 and is arranged on the ground which is near the cleaning tank 300 and is commonly used for stepping on feet, a supporting side plate 302 which is near a drain pipe 301 on the cleaning tank 300 is fixed with a ring 103, one end of the pedal 101 which is near the supporting side plate 302 is fixed with the pull rope 102 and the upper end of an elastic part 104 which is fixed on the lower wall of the pull rope 102, the elastic part 104 is arranged in a pit 105 on the ground under the pedal 101, and the pull rope 102 penetrates through the ring 103 and is fixed on the lower part of the drain pipe 301. The diversion mechanism 200 includes a left sewage chamber 210, a middle control chamber 220, and a right rain chamber 230, and the pedal 101 is located on the left side of the diversion mechanism 200 and near the sewage chamber 210. The sewage chamber 210 and the control chamber 220 are partitioned by a drain plate 211, and the control chamber 220 and the rain chamber 230 are partitioned by a partition 231. The upper end of the drain plate 211 is provided with an overflow hole 212, and the height of the lower end of the overflow hole 212 is lower than that of the upper end of the partition 231. The lower part of the drain plate 211 is provided with a drain hole 213, the bottom of the sewage chamber 210 is communicated with a sewage pipe 214, and the bottom of the rainwater chamber 230 is communicated with a rainwater pipe 232. A horizontally disposed hollow cylinder 221 is provided in the control chamber 220, the height of the cylinder 221 is greater than the width of the control chamber 220 so that the cylinder 221 cannot be rotated in the control chamber 220 in a wide range, and a vertical rod 222 vertically disposed is fixed to the upper surface of the cylinder 221. Two collars 223 in the same vertical direction are fixed on the side wall of the partition 231 in the control chamber 220, the vertical rod 222 penetrates through the collars 223, an L-shaped folding rod 224 close to the partition 231 is fixed at the top end of the vertical rod 222, the top end of the folding rod 224 is fixed in the middle of a bent rod 225 which is horizontally placed in a certain radian, and the notch of the bent rod 225 faces the drainage plate 211. The drain pipe 301 is vertically downward without being forced and its outlet is directly above the rain chamber 230, and the drain plate 301 and the partition 231 are spatially perpendicular to the support side plate 302 of the wash tank 300.

The elastic member is a spring 104.

The iron ring 303 is provided at the outlet of the drain pipe to reduce the influence of the pulling rope 102 when the outlet of the drain pipe 301 moves to the position right above the rain water chamber 230 in order to increase the weight of the outlet of the drain pipe 301.

The upper end of the drain board 211 is higher than the upper end of the partition 231, so that the outlet water column of the drain pipe 301 can be better controlled to be flushed towards the drain board 211 and fall into the control chamber 220, and the water column cannot directly enter the sewage chamber 210.

The following describes the use of the present invention in detail.

When the open-air cleaning tank 300 is to be used, a user stands on the pedal 101, presses the pedal 101, and then presses the spring 104 downwards, so that the spring 104 is in a compressed state, and the pedal 101 is tightly attached to the ground, so that the pedal 101 is supported by the ground, and the user can stably stand on the pedal 101. The pull rope 102 is pulled downwards by the pedal 101, the pull rope 102 moves around the ring 103 on the supporting side plate 302, and the pull rope 102 drives the drain pipe 301 to move, so that the outlet of the drain pipe moves from the position right above the rainwater chamber 230 to the position right above the control chamber 220. When the outlet of the drain pipe 301 is drained, the outlet wastewater column impacts the side of the drain board 211 in the control room 220, and slides down into the control room 220. The liquid level in the control chamber 220 gradually rises, and after the liquid level exceeds the water drain hole 213, part of the sewage in the control chamber 220 is drained into the sewage chamber 210 through the water drain hole 213 and then is drained into a sewage municipal pipe network through the sewage pipe 214. Since the water amount at the outlet of the drain pipe 301 is much larger than the water outlet of the drain hole 213, the liquid level in the control chamber 220 continuously rises. The cylinder 221 is also raised with the rising liquid level due to the buoyancy of the sewage in the control chamber 220 until the upper side of the cylinder 221 abuts against the lower collar 223 and is stopped by the collar 223 from further rising, at which time the lower part of the drain pipe 301 is just inside the recess of the bent rod 225. The liquid level in the control chamber 220 continues to rise, and when reaching the overflow hole 212, the liquid is discharged into the sewage chamber 210 through the overflow hole 212 and then discharged into a sewage municipal pipe network through the sewage pipe 214, so that the liquid level in the control chamber 220 is kept balanced.

When the user leaves the pedal 101 after using the cleaning tank 300, a large amount of sewage still exists in the water tank of the cleaning tank 300 to be discharged. After the pedal 101 is no longer pressed downwards by the user, under the upward rebounding action force of the spring 104, the end of the pedal 101, on which the spring 104 is fixed, is lifted upwards, so that the pulling force of the pedal 101 on the pulling rope 102 disappears and is released, the water drainage pipe 301 is no longer under the pulling force of the pulling rope 102, and under the gravity action of the water drainage pipe 301 and the iron ring 303, the outlet of the water drainage pipe 301 moves towards the position right above the rainwater chamber 230 until the water drainage pipe 301 is blocked by the bent rod 225 and cannot move towards the rainwater chamber 230. Thus, it is ensured that all of the sewage remaining in the sump of the cleaning tank 300 can be discharged into the sewage chamber 210 even if the user leaves. When the sewage in the cleaning tank 300 is drained, the outlet of the drain pipe 301 has no water, so that no sewage is supplemented into the control chamber 220, and the sewage in the control chamber 220 is continuously drained through the drain hole 213. When the liquid level in the control chamber 220 drops to the position of the cylinder 221, the cylinder 221 will also drop with the liquid level under the action of gravity, and the bent rod 225 will also drop with the drop of the cylinder 221. When the bent rod 225 is lower than the outlet of the drain pipe 301, the outlet of the drain pipe 301 continues to move directly above the rain water chamber 230 until the drain pipe 301 is in a vertical state. When the folding bar 224 abuts the upper collar 223, the cylinder 221 is no longer lowered because the folding bar 224 is blocked by the collar 223. The sewage in the control chamber 220 continues to be drained through the drainage hole 213 until the liquid level is lower than the drainage hole 213.

When it rains, the open-air cleaning tank 300 is not generally used, and therefore, no user steps on the pedal 101, the end of the pedal 101 fixed with the spring 104 is in a tilted state, and the outlet of the drain pipe 301 is located right above the rain water chamber 230. The rainwater collected by the cleaning tank 300 is drained into the rainwater chamber 230 through the drain 301 pipe and then drained into a rainwater municipal pipe network through the rainwater pipe 232.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
