Description
Technical Field
[0001] The utility model belongs to the technical field of municipal engineering and relates to an enhanced decontamination and environmentally friendly rainwater outlet with an intelligent monitoring function. Background Art
[0002] The stormwater inlet is the first barrier for rainwater discharge, an auxiliary structure of the urban drainage system, and an important part of urban road drainage. The traditional stormwater inlet collects ground rainwater directly into the stormwater inlet, discharges it to the downstream pipeline, and finally flows into the river and lake system, playing an important role in urban drainage.
[0003] However, studies have shown that rainwater runoff washes the ground, roofs, etc., and accumulates a large amount of pollutants, especially in the initial rainwater, which has a high concentration of pollutants and complex components. If it is directly discharged into the rainwater pipe network without treatment, it will cause serious pollution to urban water bodies. Most of the existing rainwater outlets only have one layer of rainwater grates with large gaps, and the ability to remove pollutants is extremely limited. When it rains or blows, it is easy to bring pollutants such as mud, fallen leaves on the ground into the rainwater outlet. If it is not cleaned for a long time, it is easy to cause the pipe network to be blocked. In severe cases, it will cause adverse effects such as large-scale water accumulation on the road surface. In addition, the existing rainwater outlets only rely on manual judgment to determine whether they have reached the level that needs to be cleaned, and there are many rainwater outlets. Manual judgment requires a lot of manpower and energy. If it is not discovered in time, it may cause serious blockage of the rainwater pipe network. There is a lack of automatic warning of staff, and lack of flexibility and wisdom. Utility Model Content
[0004] The purpose of the invention of the utility model is to solve the problems existing in the prior art such as the inability of the rainwater outlet to effectively remove a large amount of pollutants and the inability to automatically issue warnings, and to propose an enhanced decontamination and environmentally friendly rainwater outlet with an intelligent monitoring function.

After the shutters are closed, the rainwater cannot pass through the movable plate, and it directly passes over the retaining wall through the second spoiler and flows into the silt well.
[0007] Preferably, a sludge well is formed between the retaining wall and the downstream rainwater connecting pipe. The sludge well is arranged at the rear end of the initial rain enhanced decontamination device, and the two are separated by a retaining wall, which mainly plays the role of further precipitation and storage of pollutants and is connected to the rainwater connecting pipe.

[0015] The specific working principle of the utility model is as follows: a rainwater inlet is constructed on one side of the road, which is divided into several drainage sections as a whole, and each drainage section is provided with an enhanced decontamination and environmentally friendly rainwater inlet. After the initial rainwater on the road is removed by the sewage interception device in the rainwater inlet to remove pollutants such as garbage and leaves, it enters the initial rain enhanced decontamination device. Due to the action of the internal float, the floating movable plate is closed by the top support of the spoiler, so that the later rainwater directly enters the sludge well. The initial rainwater entering the initial rain enhanced decontamination device achieves the effect of rain and sewage separation through slow release and purification. Among them, the purified initial rainwater is discharged into the subsequent sludge well through the slow release outlet pipe, and the pollutants are discharged to the municipal sewage network through the sewage pipe. After the sedimentation and overflow of the sludge well, the later rainwater is directly discharged into the municipal rainwater network, and finally the purpose of enhanced purification of the initial rainwater is achieved. At the same time, multiple groups of intelligent monitoring facilities are set up as needed to evaluate the operating status of the facilities. Once the removal rate of pollutants is abnormal, it will automatically warn the staff and timely operation and maintenance.

DETAILED DESCRIPTION
[0022] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings.
[0023] Embodiment: An enhanced decontamination and environmentally friendly rainwater outlet with intelligent monitoring function, such as Figure 1-3 As shown. The device is arranged on the side of the road, and the main body of the rainwater outlet is in a concrete well body 8 (cast with concrete, and a fine stone concrete and cement mortar waterproof layer is arranged on the surface). The top surface of the well body is supported by a bracket 3 to set a rainwater grate 2. The well body 8 is arranged on both sides of the inner and outer sides of the curb stone 1 on the side of the road, and the rainwater grate is arranged on the side of the curb stone 1 facing the road. The rainwater grate 2 is laid on the upper part of the rainwater outlet, and is matched with the rainwater outlet up and down, and can be flipped by a pin shaft to facilitate the subsequent operation and maintenance of the staff. The surrounding road surface slopes toward the rainwater outlet, so that the rainwater on the road can smoothly flow into the rainwater outlet. A monitoring device A100 is provided below the rainwater grate (point A).
[0024] The sewage interception device 4 is installed under the rainwater grate, and includes, from top to bottom, a sewage interception hanging basket 40, an overflow hole 41, an overflow filter tank 42, a first spoiler 43, and a filter fine mesh 44. The sewage interception device 4 can effectively intercept garbage, leaves, mud and sand and other debris in the initial rainwater. The whole is liftable and has corresponding matching upper and lower parts to facilitate subsequent operation and maintenance by the staff.
[0025] The initial rain enhanced pollution removal device 5 is arranged below the pollution interception device 4, and includes a second spoiler 51, a movable plate 52 and a decontamination slow-release device 57 from top to bottom. A movable plate 52 with shutters 53 is arranged below the second spoiler 51. The two ends of the movable plate 52 are laid in a track 54 close to the well body 8, and the upper and lower ends of the track 54 are clamped by a bayonet 50. The four corners of the movable plate 52 are respectively connected to floating balls 56 through support rods 55 downward, and each support rod 55 is of equal length and each floating ball 56 has the same size and height. The shutter 53 is equipped with a spring to open upward. If there is no initial rainwater in the initial rain enhanced pollution removal device and it is not supported, it is in an open state; the initial rainwater enters the initial rain enhanced pollution removal device 5 from the second spoiler 51 through the shutter 53. As the water level rises, the floating ball 56 is subjected to the buoyancy of the water, so that the movable plate 52 rises along the track 54 until it presses against the second spoiler 51 above to close the shutter 53, so that the later rainwater directly enters the sludge well 7. The decontamination slow-release device 57 is arranged at the bottom, and has the functions of slow release and purification, and its emptying cycle is ≤24 h. Multiple groups are arranged in parallel as needed, and the decontamination slow-release device 57 includes an unpowered decontamination slow-release device 560, a slow-release outlet pipe 571 and a sewage pipe 572. On the one hand, the unpowered decontamination slow-release device 560 is connected to the sludge well 7 at the rear end through the slow-release outlet pipe 571. It operates fully automatically, does not require power consumption, and can automatically output the purified initial rainwater, achieving the purpose of unpowered, fully automatic, slow-release water delivery; on the other hand, the unpowered decontamination slow-release device 570 is connected to the sewage pipe network through the sewage pipe 572, and can automatically discharge the pollutants enriched at the bottom of the facility, achieving the purpose of sewage purification.
[0026] The sludge well 7 is arranged at the rear end of the primary rain enhanced pollution removal device 5, and the two are separated by a retaining wall 6, which mainly plays the role of further sedimentation and storage of pollutants, and is connected to the downstream rainwater connecting pipe 9. The inlet end of the downstream rainwater connecting pipe 9 is provided with a monitoring facility B101, and is connected to the rainwater pipe network.
[0027] When the rainfall is small, the rainfall runoff flows through the road surface and converges to the rainwater grate 2. After the interception of the sewage interception device 4 (mainly through the interception of sewage interception basket 40 and the filtering of the filter fine mesh), it is accumulated in the initial rain enhanced sewage removal device 5. The initial rainwater is slowly purified by the slow release and purification effect of the unpowered decontamination slow release device 570 inside the initial rain enhanced sewage removal device 5 (emptying cycle ≤ 24h). The purified rainwater flows into the sludge well 7 through the slow release outlet pipe 571 and finally merges into the municipal rainwater pipe network; the enriched pollutants are discharged to the sewage pipe network through the sewage pipe 572.
[0028] When the rainfall is large, in addition to the above situation, in the sewage interception device 4, the initial rainwater passes through the lower filter fine mesh 44 and enters the initial rain enhanced sewage removal device 5, and the later rainwater overflows through the overflow hole 41 into the overflow filter tank 42, and enters the subsequent after further filtration. As the initial rainwater inside increases, under the action of buoyancy, the movable plate 52 (with a floating ball 56 connected by a support rod 55 below) in the initial rain enhanced sewage removal device 5 moves upward along the track 54 until the shutter 53 is closed by the supporting action of the second spoiler 51, so that the later rainwater directly enters the silt well 7, and after further removing pollutants, the overflow water flows to the downstream rainwater connecting pipe 9.
[0029] In order to better play the initial rainwater purification function of the facility, monitoring facilities 10 are respectively set at point A below the rainwater grate 2 and point B of the downstream rainwater connecting pipe 9, namely monitoring facility A100 and monitoring facility B101. The monitoring facility 10 is set in multiple groups as needed to monitor parameters such as water volume and suspended solids (SS) concentration in real time or periodically, and comprehensively evaluate the operation status of the facility. When it is in an abnormal state, it reminds the staff to maintain the facility in time. The operation and maintenance warnings issued by the monitoring facilities vary according to the designed SS removal efficiency of the facility, and are determined according to the actual situation. The following is one of the cases. For example, the designed SS removal efficiency is 50%, and the monitoring facility detects that the SS concentration at point A is C. A , the SS concentration at point B is C B When the automatic monitoring detects that the SS removal rate is greater than or equal to 50%, the facility is displayed as normal; when the automatic monitoring detects that the SS removal rate is less than 50%, an early warning signal is automatically issued to the staff to remind them to clean or replace it in time. Therefore, the monitoring facilities can automatically issue early warning signals, and the staff does not need to manually judge the condition of the facilities, which can prevent some facilities from being out of operation and maintenance for a long time, and the road surface is not discovered until water accumulates, causing difficulties in operation and maintenance.
[0030] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
