Description

Technical Field

[0001] The invention relates to the technical field of diversion wells, and in particular to a rainwater and sewage diversion well with a diversion cavity. Background Art

[0002] In urban environments, there are many types of ground covers. Pollutants such as particulate matter emitted by automobile exhaust, oil, and rubber wear particles accumulate on the road surface. There will also be similar oil and dust on the parking lot surface. When it rains in the early stage, the rain will wash away these pollutants and bring them into the stormwater drainage system. There is also the impact of garbage and waste; there may be garbage and waste such as plastic waste, paper, and food residues on urban streets and public places. These garbage will release the pollutants contained in them during rainfall. For example, when discarded batteries are soaked in rainwater, they will leak heavy metals (such as zinc, manganese, etc.); rotten food residues will release nutrients such as nitrogen and phosphorus, as well as microorganisms such as bacteria and viruses. Landfills are also an important source of pollution. When rainwater washes the surface of the landfill, it will bring high concentrations of organic matter, heavy metals and other pollutants in the leachate into the initial rainwater. These leachates are liquids produced by the decomposition of garbage during the landfill process, and contain a large amount of harmful substances; in response to the above situation, rainwater and sewage diversion wells are needed to divert and treat the initial rainwater;

[0003] For example, the prior art application number CN202322713501.1 discloses a non-powered rainwater and sewage diversion well for intercepting sewage and draining water, including a rainwater and sewage diversion well body, a buoyancy chamber and a float chamber, wherein the front side of the rainwater and sewage diversion well body is connected to a water inlet pipe, and the rear side of the rainwater and sewage diversion well body is connected to a rainwater outlet pipe, a partition is fixed on one side of the interior of the rainwater and sewage diversion well body, and a buoyancy chamber is arranged on the inner side of the partition, a float chamber is arranged on the side of the rainwater and sewage diversion well body close to the rainwater outlet pipe, a pulley assembly is installed on one side of the inner wall of the rainwater and sewage diversion well body, and the pulley assembly includes a support rod and a pulley, the support rod and the pulley are both provided with two groups, and a pulley is rotatably installed on the top of the support rod, and stainless steel chains are wound around the outer sides of the two groups of pulleys, a stainless steel buoy is fixed to the bottom of the stainless steel chain close to the buoyancy chamber side, and a stainless steel float is fixed to the bottom of the stainless steel chain close to the float chamber side;

[0004] It is known through actual use of the above-mentioned prior art that when the initial rainwater is small, the dirty rainwater will be directly discharged to the sewage treatment plant through the sewage outlet for treatment. When the rainwater is large, the float box will float up and move upward, and the float ball will fall to block the sewage outlet. Then the clear rainwater will be collected through the rainwater outlet pipe, thereby achieving the purpose of diverting the initial rainwater and sewage. However, it is found during use that when the water flow fluctuates greatly, the float box is prone to violent shaking, causing the float ball to pull, resulting in inaccurate falling position of the float ball, and failing to block the sewage outlet well, causing a large amount of clear rainwater to be discharged into the sewage outlet, resulting in poor rainwater and sewage diversion effect. For this reason, we have improved the above-mentioned prior art according to actual usage. Utility Model Content

[0005] In view of the problem that when the water flow fluctuates greatly, the float box is prone to shake violently and pull the float, resulting in inaccurate falling position of the float, and failure to block the sewage outlet well, so that clear rainwater is discharged into the sewage outlet in large quantities, resulting in poor rainwater and sewage diversion effect, the present invention aims to provide a rainwater and sewage diversion well with a diversion chamber.

[0006] To achieve the technical purpose, the solution of the present invention is: a rainwater and sewage diversion well with a diversion chamber, including a well body, wherein the two sides and the bottom of the well body are sequentially provided with an inlet pipe, a rainwater outlet pipe and a sewage outlet, the well body is provided with a diversion chamber and a float chamber, the diversion chamber and the float chamber are sequentially movably provided with a float and a float, a stabilizing member is provided between the float and the float; the stabilizing member includes a cross bar, a cross bar and a vertical bar, the lower surface of the cross bar is integrally provided with a cross bar and a vertical bar, the cross bar and the vertical bar are respectively slidably provided with the float and the float.

[0007] Preferably, a cover plate is provided at the upper end of the well body through a hinge, a partition plate is integrally provided on the bottom wall of the well body, a gap is provided between the top wall of the cover plate and the upper end of the partition plate, and a through hole is also provided in the partition plate for connecting the diversion chamber and the float chamber.

[0008] Preferably, a flow guide frame is fixed to the inner wall of the well body and the flow guide frame is connected to the water inlet pipe, an opening is provided at one end of the flow guide frame away from the water inlet pipe, and a filter plate is provided in the flow guide frame.

[0009] Preferably, a slide groove is provided in the upper end of the guide frame, and the filter plate is slidably installed in the slide groove.

[0010] Preferably, a cross slide is provided through the buoyancy box, a through groove is also provided through the buoy, the vertical rod is inserted into the through groove, the cross rod is inserted into the cross slide, and the outer surface of the cross rod is fixed to the partition.

[0011] Preferably, a U-shaped frame is fixed to the upper surface of the partition by bolts, a steel rope passes through the U-shaped frame and the two ends of the steel rope are respectively welded to the upper surface of the buoyancy box and the float ball; the outer surfaces of the steel rope, the cross rod and the vertical rod are all provided with a solid lubricating layer.

[0012] Preferably, a sealing ring is fixed to the lower surface of the float by glue; a convex ring is integrally provided at the edge of the sewage outlet, and a No. 1 slope is respectively provided on the inner and outer sides of the convex ring.

[0013] Preferably, the bottom wall of the well body is provided with a second slope;

[0014] Beneficial effects:

[0015] 1. In the present invention, when the buoyancy box floats up, the buoyancy box will slide around the cross rod in the stabilizing member, and when the floating ball falls, it will slide down around the vertical rod. The cross rod and the vertical rod can prevent the buoyancy box and the floating ball from shaking violently, and ensure that the floating ball falls accurately so that the floating ball can be accurately blocked with the sewage outlet, which can greatly improve the rainwater and sewage diversion effect;

[0016] 2. When the float falls and the sewage outlet is blocked, the sealing ring and the convex ring opening will be pressed tightly together. Since the sealing ring is made of soft rubber and the inner and outer walls of the convex ring are sloped, it is not easy for sand and dust to accumulate on the outer periphery of the convex ring. After the sealing ring and the convex ring are pressed tightly together, the sealing performance of the float on the sewage outlet can be increased to prevent the loss of clear rainwater.

[0017] 3. A solid lubricating layer is provided on the outer surface of the cross rod, the vertical rod and the steel rope, which can increase the sliding and antifreeze properties between the steel rope and the U-shaped frame, as well as between the buoyancy box, the floating ball and the cross rod and the vertical rod, and prevent the buoyancy box and the anti-floating ball from being unable to float due to low temperature, while reducing the floating resistance of the buoyancy box and the floating ball.

[0029] The invention of this application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In order to clearly and completely describe the technical solution, the following embodiments are selected for illustration; based on the contents recorded in this application, other embodiments obtained without creative work are all within the scope of protection of the present invention.

[0030] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of clearly describing the present embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0031] like Figures 1 to 10 As shown, an embodiment of the present invention provides a rainwater-sewage diversion well with a diversion chamber, including a well body 1, wherein a water inlet pipe 2, a rainwater outlet pipe 3 and a sewage outlet 6 are sequentially arranged on both sides and the bottom of the well body 1, a diversion chamber 4 and a float chamber 5 are arranged in the well body 1, a float 8 and a float 7 made of metal steel are movably arranged in the diversion chamber 4 and the float chamber 5 in turn, and a stabilizing member 9 is arranged between the float 8 and the float 7; the stabilizing member 9 includes a cross bar 91, a cross bar 92 and a vertical bar 93, a cross bar 92 and a vertical bar 93 are integrally arranged on the lower surface of the cross bar 91, and the cross bar 92 and the vertical bar 93 are respectively slidably arranged with the float 7 and the float 8 to limit the floating position of the float 8 and the float 7.

[0032] In the initial state, the float 8 and the pontoon 7 are balanced. In order to ensure that the float 8 and the pontoon 7 can be balanced, first ensure that the length of the steel rope 23 is long enough so that when the water level drops, the pontoon 7 can have enough displacement space to pull the float 8. When calculating the length of the steel rope 23, it is necessary to consider the maximum change in the water level. For example, if the maximum drop in the water level is expected to be h, and the radius of the pontoon 7 is r, then the reserved length of the steel rope 23 in the vertical direction should be at least h+r plus a certain margin (such as 0.5-1 meter) to ensure that even in the case of extreme water level drops, the pontoon 7 can still pull the float 8 to regain balance;

[0033] The material of the buoyancy tank 7 can be aluminum alloy, stainless steel, or titanium alloy.

[0034] Aluminum alloy characteristics: Aluminum alloy density is relatively small, generally 2.7-2.8g / cm 3 About, which makes it easier to obtain sufficient buoyancy in the water. For example, compared with steel, the same volume of aluminum alloy is lighter and more conducive to floating. It has good corrosion resistance. A dense oxide film will form on the surface of the aluminum alloy, which can effectively prevent it from being corroded in water. This oxide film can protect the pontoon 7 to a certain extent and extend its service life. The strength of aluminum alloy is relatively high and can withstand certain external forces. It can withstand the impact of rainwater on the pontoon 7. It can maintain the integrity of the structure in a complex environment;

[0035] Stainless steel characteristics: The density of stainless steel is about 7.9-8.0g / cm 3 . It has excellent corrosion resistance, especially in salty water, and can resist the erosion of corrosive ions such as chloride ions. This is because stainless steel contains alloy elements such as chromium and nickel, which can improve its corrosion resistance. Stainless steel has good strength and toughness. It can withstand greater pressure and tensile force, and is suitable for making large pontoons 7 or pontoons 7 that need to withstand heavier loads.

[0036] Titanium alloy characteristics: Titanium alloy density is generally 4.5-4.8g / cm 3 It has excellent corrosion resistance and can maintain good chemical stability in most harsh water environments (including corrosive media such as strong acids and alkalis). This characteristic gives the titanium alloy pontoon 7 unique advantages in some special environments. The strength of titanium alloy is comparable to that of steel, but it is much lighter than steel. Its high specific strength (ratio of strength to density) can reduce the overall weight while ensuring the strength of the pontoon 7, thereby improving buoyancy efficiency;

[0037] refer to Figure 1A cover plate 15 is provided at the upper end of the well body 1 through a hinge, and a partition plate 10 is integrally provided on the bottom wall of the well body 1. A gap is provided between the top wall of the cover plate 15 and the upper end of the partition plate 10 to increase the speed of entry of clear rainwater. 3-6 through holes 11 are also provided in the partition plate 10 to connect the diversion chamber 4 and the buoyancy chamber 5.

[0038] refer to Figure 2 and Fig.10 A guide frame 12 is fixed to the inner wall of the well body 1 and is connected to the water inlet pipe 2. An opening is provided at one end of the guide frame 12 away from the water inlet pipe 2, and a filter plate 13 is provided in the guide frame 12. A chute 14 is provided in the upper end of the guide frame 12, and the filter plate 13 is slidably installed in the chute 14 to filter larger impurities in the rainwater, to prevent larger impurities from being between the float 8 and the sewage outlet 6, resulting in reduced sealing performance of the float 8 to the sewage outlet 6. When cleaning, the filter plate 13 can be pulled up to move out of the guide frame 12.

[0039] refer to Figure 5 , Figure 6 , Figure 7 A cross slot 18 is provided through the buoyancy box 7, a through slot 19 is also provided through the buoyancy ball 8, the vertical rod 93 is inserted into the through slot 19, the cross rod 92 is inserted into the cross slot 18, and the outer surface of the cross rod 91 is fixed to the partition 10. A U-shaped frame 22 is fixed to the upper surface of the partition 10 by bolts, a steel rope 23 is passed through the U-shaped frame 22, and the two ends of the steel rope 23 are respectively welded to the upper surface of the buoyancy box 7 and the buoyancy ball 8;

[0040] refer to Figure 7 The outer surfaces of the steel rope 23 , the cross rod 92 and the vertical rod 93 are all provided with a solid lubricating layer 24 .

[0041] refer to Figure 7 and Figure 8 The lower surface of the float 8 is fixed with a sealing ring 20 made of soft rubber by glue; the edge of the sewage outlet 6 is integrally provided with a convex ring 16, and the inner and outer sides of the convex ring 16 are respectively provided with a No. 1 slope 17 of 30-80 degrees to form a drop to prevent sand and gravel accumulation.

[0042] refer to Fig. 9 The bottom wall of the well body 1 is provided with a second slope 21 for collecting sand and gravel particles in rainwater to facilitate the sedimentation of sand and gravel particles. The cover plate 15 needs to be opened for regular cleaning.

[0043] Working principle: Initially, the float box 7 is level with the float ball 8, and the float ball 8 does not block the sewage outlet 6 tightly. The initial dirty rainwater with a small flow rate enters the diversion cavity 4 in the well body 1 through the water inlet pipe 2 and is directly discharged from the sewage outlet 6 to the sewage plant for collection and treatment;

[0044] After the initial rainwater is over, the rainwater becomes larger and clearer, and the clear rainwater will increase in the diversion chamber 4. When the clear rainwater is higher than the through hole or the partition 10, it will enter the buoyancy chamber 5 and then make the buoyancy chamber 7 float upward. As the buoyancy chamber 7 floats up, the float ball 8 will fall and tightly seal the sewage outlet 6. The clear rainwater will be discharged and collected through the rainwater outlet pipe 3, realizing the separation of rainwater and sewage.

[0045] When the buoyancy box 7 floats up, the buoyancy box 7 will slide around the cross rod 92 in the stabilizing member 9, and the floating ball 8 will slide down around the vertical rod 93 when falling. The cross rod 92 and the vertical rod 93 can prevent the buoyancy box 7 and the floating ball 8 from shaking violently, and ensure that the floating ball 8 falls accurately so that the floating ball 8 can be accurately blocked with the sewage outlet 6, which can greatly improve the rainwater and sewage diversion effect;

[0046] The process of the floating ball 8 falling and blocking the sewage outlet 6 will first make the sealing ring 20 and the opening of the convex ring 16 tightly pressed against each other. Since the sealing ring 20 is made of soft rubber and the inner and outer walls of the convex ring 16 are both provided with slopes, it is not easy for sand and dust to accumulate on the outer periphery of the convex ring 16. After the sealing ring 20 and the convex ring 16 are tightly pressed against each other, the sealing performance of the floating ball 8 on the sewage outlet 6 can be increased.

[0047] The outer surfaces of the cross bar 92, the vertical rod 93 and the steel rope 23 are all provided with a solid lubricating layer 24, which can increase the sliding property and antifreeze property between the steel rope 23 and the U-shaped frame 22, the buoyancy box 7, the floating ball 8 and the cross bar 92 and the vertical rod 93, and can prevent the buoyancy box 7 and the anti-floating ball 8 from being unable to float due to low temperature, and at the same time make the floating resistance of the buoyancy box 7 and the floating ball 8 small. The solid lubricating layer 24 can be grease. These lubricants can effectively reduce friction and prevent water from accumulating and freezing at the contact part. A coating such as graphite powder can also be used, which can maintain good lubrication performance at low temperatures.

[0048] Thickness setting of solid lubricating layer 24:

[0049] If the sliding of the float 8 on the vertical rod 93 is caused by the slow change of the water level, the speed is relatively low (for example, the rising or falling speed of the float 8 is within a few millimeters per second), in a fresh water environment, it is more appropriate to set the thickness of the solid lubricating layer at 10-30 microns;

[0050] When the float 8 slides on the vertical rod 93 at a speed of several centimeters per second due to water flow fluctuations, the thickness of the solid lubricating layer can be adjusted to 30-80 microns in a fresh water environment. In a seawater environment, the thickness is preferably 60-120 microns;

[0051] In some special cases, such as when the float 8 is in a turbulent water flow, the sliding speed of the float 8 on the vertical rod 93 may reach tens of centimeters per second or even higher. In a fresh water environment, the thickness of the solid lubricating layer may need to be 80-200 microns.

[0052] For the buoyancy box 7 sliding on the cross bar 92: for medium-speed sliding, when sliding on the cross bar 92 at a speed of several centimeters per second, in a fresh water environment, the thickness of the solid lubricating layer is preferably 40-100 microns. For high-speed sliding scenarios, the thickness may need to be 100-250 microns.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any slight modification, equivalent substitution and improvement made to the above embodiment based on the technical essence of the present invention should be included in the protection scope of the technical solution of the present invention.
