Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rainwater diversion wells, and specifically relates to a rainwater and sewage diversion well. Background Art
[0002] The rainwater and sewage diversion well separates and discharges rainwater and sewage. The rainwater is discharged into the river, and the sewage is discharged into the sewage treatment plant, thereby avoiding pollution to the river and the environment.
[0003] Chinese Patent CN214144057U discloses a rainwater diversion well with a trash cage, which includes a cylinder body. A horizontally arranged partition plate is arranged in the cylinder body, dividing the cylinder body into an upper chamber and a lower chamber. The upper chamber is provided with a water inlet and a first water outlet, and the lower chamber is provided with a second water outlet.
[0004] The above structure has the following two defects: 1. The low end of the second water outlet is higher than the bottom of the cylinder body, resulting in difficulty in completely discharging the sewage in the cylinder body; 2. Impurities accumulate at the bottom of the cylinder body and will accumulate more and more, resulting in blockage of the second water outlet; 3. The setting of the partition plate will increase the cost of the rainwater and sewage diversion well. Content of the Utility Model
[0005] In order to solve the technical problems in the background art, the utility model discloses a rainwater and sewage diversion well.
[0006] The utility model provides a rainwater and sewage diversion well, which includes a cylinder body. A sewage inlet, a sewage discharge port and a rainwater and sewage discharge port are arranged on the cylinder body. A vertically arranged partition plate is arranged in the cylinder body. The sewage inlet and the rainwater and sewage discharge port are located on both sides of the partition plate, and the sewage discharge port is arranged at the bottom of the cylinder body;
[0007] The sewage inlet and the rainwater and sewage discharge port are arranged at positions close to the top of the cylinder body;
[0008] The same first floating ball and second floating ball are also installed in the cylinder body;
[0009] The tops of the first floating ball and the second floating ball are connected by a hinge rod. The middle position of the hinge rod is hinged to the cylinder body, and the hinge point is located at a position close to the first floating ball;
[0010] The first floating ball corresponds to the sewage discharge port, and by swinging up and down of the first floating ball, the sewage discharge port is separated from or blocked;
[0011] When the first floating ball blocks the sewage discharge port, there is a gap between the first floating ball and the sewage discharge port.
[0012] Since the moment of the first floating ball is less than that of the second floating ball, the first floating ball is located away from the sewage outlet. When it does not rain, sewage enters the cylinder from the sewage inlet and is discharged from the sewage outlet. When it rains, rainwater and sewage enter the cylinder. If the water volume is large and the sewage outlet is difficult to drain in time, the liquid level in the cylinder will gradually rise, generating buoyancy on the second floating ball. The second floating ball rises and the first floating ball descends, thus blocking the sewage outlet. As the liquid level in the cylinder rises again, the water in the cylinder will cross the partition and be discharged from the rain and sewage outlet. At this time, due to the pressure difference between the inside and outside of the sewage outlet, the first floating ball will be stably blocked at the sewage outlet under the action of water pressure. When the rain stops, the water in the cylinder will gradually drain out from the gap between the first floating ball and the sewage outlet. When the pressure inside and outside the sewage outlet is balanced, the first floating ball resets to a position away from the sewage outlet. The beneficial effects of the present utility model are as follows: 1. The sewage outlet is arranged at the bottom of the cylinder, so that impurities will not remain at the bottom of the cylinder, and the problem of sewage outlet blockage is also solved; 2. The traditional horizontally arranged partition is cancelled, reducing the cost.
[0013] The specific structure of the gap provided between the first floating ball and the sewage outlet is that the sewage outlet is configured such that the shape of its connection with the first floating ball does not match the first floating ball.
[0014] The partition is integrally formed with the cylinder, with high processing difficulty and high cost. Based on this, a further improvement lies in that two symmetrically arranged clamping grooves are provided inside the cylinder; the clamping grooves are composed of two symmetrically and vertically arranged convex strips; the partition is inserted into the clamping grooves.
[0015] Since the sewage may contain impurities and easily block the sewage outlet, based on this, a further improvement lies in that a semi-circular sewage interception basket is installed inside the cylinder below the sewage inlet; there is a spacing between the sewage interception basket and the bottom of the cylinder; multiple water leakage holes are provided at the lower end of the sewage interception basket.
[0016] The sewage interception basket is directly fixed to the side of the cylinder, with a relatively complex installation structure and high installation difficulty, and the position structure of the sewage interception basket is also unstable. Based on this, a further improvement lies in that the bottom of the sewage interception basket is provided with legs that abut against the bottom of the cylinder.
[0017] Only relying on the water leakage holes at the bottom of the sewage interception basket for drainage, the drainage capacity is poor, and the water leakage holes are also easily blocked by sundries. Based on this, a further improvement lies in that a horizontally arranged fixing ring is provided at the top of the sewage interception basket; the fixing ring fits with the inner wall of the cylinder; the side of the sewage interception basket is connected to the inner side of the fixing ring; multiple oblong water leakage grooves and circular through holes are provided on the side of the sewage interception basket.
[0018] Since the through holes and the water leakage grooves are independently arranged, both are prone to being blocked by sundries. Based on this, a further improvement is as follows: the diameter of the through holes is larger than the width of the water leakage grooves, the through holes are communicated with the water leakage grooves, and are arranged at the middle position of the water leakage grooves; each through hole is symmetrically arranged with respect to the water leakage groove.
[0019] To improve the installation position accuracy and position stability of the sewage interception basket, a further improvement is as follows: right-angled positioning grooves are provided at both ends of the straight edge of the fixing ring and are clamped with the convex strips.
[0020] When the rain and sewage mixed water crosses the partition board and discharges outward from the rain and sewage discharge port, impurities will be mixed in, which is likely to cause pollution. Based on this, a further improvement is as follows: a baffle vertically extending towards the sewage inlet direction is further provided at the top of the partition board; a plurality of filter holes are provided on the baffle; a gap is provided between the side part of the baffle and the inner wall of the cylinder body.
[0021] The setting of the baffle will cause the drainage volume to become smaller. Based on this, a further improvement is as follows: a through communication pipe is also inserted into the partition board to communicate the cavities on both sides of the partition board. Description of the Drawings

Detailed implementation mode
[0033] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.
[0034] As Figure 1 and Figure 3 shown, the present utility model discloses a rain and sewage separation well, including a cylinder body 1. A sewage inlet 2 and a rain and sewage discharge port 4 are arranged at a position near the top of the cylinder body 1, and the sewage inlet 2 and the rain and sewage discharge port 4 are arranged oppositely. A sewage discharge port 3 is arranged at the bottom of the cylinder body 1 and is connected with a 90° elbow outward, so that the outlet of the sewage discharge port 3 faces horizontally.
[0035] A vertically arranged partition board 5 is arranged inside the cylinder body 1, dividing the inside of the cylinder body 1 into two areas. The sewage inlet 2 is located on one side of the partition board 5, and the sewage outlet and the rain and sewage discharge port 4 are located on the other side of the partition board 5. As Figure 2 and Figure 5 shown, two symmetrically arranged clamping grooves 11 are arranged on the inner wall of the cylinder body 1; each clamping groove 11 is composed of two symmetrically and vertically arranged ribs 12; the partition board 5 is inserted into the clamping groove 11. In this way, the partition board 5 can be disassembled, thus simplifying the structure of the cylinder body 1 and reducing the cost of the cylinder body 1.
[0036] A vertically arranged column is also installed inside the cylinder body 1. The top of the column is hinged with an articulated rod 8, and the hinge point is eccentric. The two ends of the articulated rod 8 are respectively connected with the same first floating ball 6 and second floating ball 7 through a first connecting rod 15 and a second connecting rod 15. The first floating ball 6 corresponds to the sewage discharge port 3. The length of the first connecting rod 15 is greater than that of the second connecting rod 15, and the hinge point is located near the first floating ball 6. In this way, when there is no water in the cylinder body 1, the moment of the second floating ball 7 is greater than that of the first floating ball 6, so that the first floating ball 6 rises and the second floating ball 7 descends to abut against the bottom of the cylinder body 1. When there is water in the cylinder body 1 and the second floating ball 7 floats, the first floating ball 6 descends and blocks the sewage discharge port 3.
[0037] The hinge point of the articulated rod 8 is covered with a housing 16 to prevent impurities such as silk threads from being involved in the hinge point and affecting the normal swing of the articulated rod 8.
[0038] Both the first floating ball 6 and the second floating ball 7 are made of stainless steel. Moreover, at the connection between the sewage outlet 3 and the first floating ball 6, their shapes do not match, resulting in a gap between the first floating ball 6 and the sewage outlet 3.
[0039] A sewage interception basket 9 is also installed inside the cylinder body 1, which is arranged directly below the sewage inlet 2. As Figure 8 and Figure 9 shown, the sewage interception basket 9 is semi-circular, and a horizontally arranged fixing ring 93 is provided at its top. The fixing ring 93 fits against the inner wall of the cylinder body 1; the side part of the sewage interception basket 9 is connected to the inner side of the fixing ring 93, so that there is a spacing between the side wall of the sewage interception basket 9 and the inner wall of the cylinder body 1. A U-shaped connecting rod 15 with an opening facing downwards is also connected between the opposite sides of the arc-shaped part of the fixing ring 93, which is used to improve the structural stability of the sewage interception basket 9 and also facilitate the removal of the sewage interception basket 9. As Figure 2 and Figure 5 shown, right-angled positioning grooves 96 are provided at both ends of the straight edge of the fixing ring 93, which are clamped with the convex strips 12, so as to improve the installation position accuracy and position stability of the sewage interception basket 9. A plurality of water leakage holes 91 are opened at the bottom of the sewage interception basket 9, and a leg 92 integrally formed is provided at the bottom of the sewage interception basket 9, so that there is a spacing between the bottom of the sewage interception basket 9 and the bottom of the cylinder body 1, facilitating water to fall from the water leakage holes 91. A plurality of oblong water leakage grooves 94 and circular through holes 95 are opened at the side part of the sewage interception basket 9, which are used to increase the drainage volume of the sewage interception basket 9. The diameter of the through hole 95 is larger than the width of the water leakage groove 94, the through hole 95 is communicated with the water leakage groove 94, and is arranged at the middle position of the water leakage groove 94; each through hole 95 is symmetrically arranged with respect to the water leakage groove 94. With such a setting, it is possible to prevent sundries from blocking at the through hole 95 and the water leakage groove 94.
[0040] As Figure 4 shown, a baffle 13 extending vertically towards the sewage inlet 2 is further provided at the top of the partition plate 5; a plurality of filter holes are provided on the baffle 13; there is a gap between the side part of the baffle 13 and the inner wall of the cylinder body 1. In this way, it is possible to prevent the rain and sewage mixed water from passing over the partition plate 5 and taking out impurities when discharging out from the rain and sewage outlet 4, causing pollution.
[0041] The setting of the baffle 13 will cause the drainage volume to become smaller. Therefore, as Figure 6 and Figure 7 shown, a through communication pipe 14 is also inserted into the partition plate 5 to connect the cavities on both sides of the partition plate 5.
[0042] Since the moment of the first floating ball 6 is less than that of the second floating ball 7, the first floating ball 6 is located away from the sewage discharge port 3. When it does not rain, sewage enters the cylinder 1 from the sewage inlet 2 and is discharged from the sewage discharge port 3. When it rains, rainwater and sewage enter the cylinder 1 together. If the amount of water is large and the sewage discharge port 3 has difficulty draining in time, the liquid level in the cylinder 1 will gradually rise, generating buoyancy on the second floating ball 7. The second floating ball 7 rises and the first floating ball 6 drops, thus blocking the sewage discharge port 3. As the liquid level in the cylinder 1 rises again, the water in the cylinder 1 will overflow the partition 5 and be discharged from the rain-sewage discharge port 4. At this time, due to the pressure difference between the inside and outside of the sewage discharge port 3, the first floating ball 6 will be stably blocked at the sewage discharge port 3 under the action of water pressure. When the rain stops, the water in the cylinder 1 will gradually drain out from the gap between the first floating ball 6 and the sewage discharge port 3. When the pressure inside and outside the sewage discharge port 3 is balanced, the first floating ball 6 returns to the position away from the sewage discharge port 3. The beneficial effects of the present utility model are as follows: 1. The sewage discharge port 3 is arranged at the bottom of the cylinder 1, so that impurities will not remain at the bottom of the cylinder 1, and the problem of blockage of the sewage discharge port 3 is also solved; 2. The traditional horizontally arranged partition 5 is cancelled, reducing the cost.
[0043] Enlightened by the above ideal embodiments based on the present utility model, through the above description, relevant staff can completely make various changes and modifications within the scope not deviating from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
