Description

Technical Field

[0001] The invention relates to the technical field of rainwater discharge outlets, and in particular to a rainwater discharge outlet detection and control system. Background Art

[0002] Since the rainwater and industrial water pipe networks in the factory area were built earlier, they have been in use for a long time and are seriously aged. Most of them are buried underground, making maintenance and replacement difficult. As a result, a small amount of groundwater and unknown water seep into the pipe network in the factory area, resulting in unknown water flowing at the rainwater outlet. In addition, part of the fire emergency water generated by sudden accidents in local areas of the factory will also flow out from the rainwater outlet, and the original drainage end of the rainwater outlet is located along the natural river (Yangtze River);

[0003] The existing preliminary plan is to directly connect the drainage end of the rainwater discharge outlet to the sewage treatment workshop. Due to the complex water sources at the drainage end, there are different problems. For example, groundwater is basically not polluted and can be directly discharged into natural rivers, while unknown water has different pollution (such as BOD5, COD, PH, etc.). Fire emergency water is mainly polluted by suspended solids. In different areas and at different time periods, the water discharged from the rainwater discharge outlet is not exactly the same. If all of it is directly introduced into the sewage treatment workshop, the workload and work intensity of the original sewage treatment workshop will be greatly increased, and there may even be a problem of partially renovating the sewage treatment workshop. Directly discharging the above-mentioned untreated water from different sources into natural rivers has the risk of polluting water sources, which does not meet the relevant national environmental protection requirements.

[0004] In view of this, there is an urgent need for a rainwater discharge outlet detection and control system that can solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Embodiment 1

[0032] Please see attached Figure 1-2

[0033] A sewage information detection pool 1, a sewage information collection system 2, a water collection pool 3 and a sewage treatment workshop 4, wherein one end of the rainwater discharge port is located in the sewage information detection pool 1, the sewage information collection system 2 is arranged in the sewage information detection pool 1, and the water collection pool 3 is connected to the sewage information detection pool 1 through the sewage information collection system 2, and the sewage treatment workshop 4 is connected to the water collection pool 3 by pipeline;

[0034] The sewage information collection system 2 includes a sewage information collection sensor 20 located in the sewage information detection pool 1, a first water pump 21, a second water pump 22 and a sewage information processing console 23 arranged on the ground. The sewage information collection sensor 20 sends the collected sewage information to the sewage information processing console 23. The sewage information processing console 23 completes information processing according to the received sewage information and sends control signals to the first water pump 21 and the second water pump 22 respectively. The discharge outlet of the first water pump 21 is located in the water collection pool 3, and the discharge outlet of the second water pump 22 is located in the river outside the factory.

[0035] In actual application, unknown water from the rainwater outlet is collected by building a new sewage information detection pool 1 at the rainwater outlet, and the pollution of the unknown water is detected by the sewage information collection sensor 20 set in the sewage information detection pool 2. After the detected sewage information is transmitted to the sewage information processing console 23 on the ground, the sewage information processing console 23 decodes and analyzes it, and then determines the final destination of the water in the sewage information detection pool 1 according to the analysis results. For example, the unknown water without pollution or pollution within the allowable range is directly discharged into a natural river (such as the Yangtze River) through the second pump 22, and the unknown water with strong pollution is discharged into a natural river (such as the Yangtze River) through the first pump 21. It is discharged into the water collection tank 3, and finally discharged into the natural river after decontamination treatment in the sewage treatment workshop 4. It should be noted that according to the different locations of the water collection tank 3 and the sewage treatment workshop 4, for example, when the water collection tank 3 is at a high place, the sewage in the water collection tank 3 can be naturally discharged to the sewage treatment workshop 4 without the assistance of external force (such as using a water pump). Otherwise, it is necessary to set a drainage pump in the water collection tank 3 to achieve the purpose of discharging the sewage in the water collection tank 3 to the sewage treatment workshop 4. At the same time, considering the normal maintenance of the sewage treatment workshop 4 and the sewage treatment efficiency of the sewage treatment workshop 4, a control valve is provided on the pipeline from the water collection tank 3 to the sewage treatment workshop 4.

[0036] Specifically, the start and stop states of the first water pump 21 and the second water pump 22 are opposite; the unknown water is discharged to the natural river and the sewage treatment workshop 4 respectively according to its degree of pollution, so there is no situation where the first water pump 21 and the second water pump 22 need to work at the same time.

[0037] Specifically, the sewage information collection sensor 20 includes a water level information collection sensor and a pollutant parameter information collector; the unknown water is mainly composed of rainwater, groundwater and fire-fighting water, etc. Although it forms a constant flow of water at the rainwater discharge outlet, its flow rate is generally not too large. Therefore, the detection information of the sewage information collection system 2 is usually detected and discharged after a certain amount of pool water in the sewage information detection pool 1 accumulates. At present, the water level is detected by using a water information collection sensor. When the unknown water in the sewage information detection pool 1 reaches a certain water level, the sewage information processing console 23 receives the water level information, and then processes the pollution information of the pollutant parameter information collector, and opens the first pumping pump 21 or the second pumping pump 22 for drainage according to the specific situation. After the drainage reaches a certain level, the first pumping pump 21 or the second pumping pump 22 is closed according to the water level information of the water level information collection sensor;

[0038] It should also be noted that due to the different sources of unidentified water in the factory, the corresponding water pollution indicators to be detected are also different. For example, the detection indicator of the dock area is mainly oil content, the detection indicator of the shipbuilding area is mainly CODcr, the detection indicator of the electrical equipment workshop area is mainly pH value, and the detection indicator of the living area is mainly BOD5, etc. Depending on the area, the pollutants detected by the pollutant parameter information collector are not exactly the same. In some areas, there is even a need to detect 2-3 types of pollutant information at the same time.

[0039] Embodiment 2

[0040] Please see attached Figure 3-5

[0041] The water collecting pool 3 is provided with at least one circulation pool 30, and an overflow water guide assembly 5 is provided between the water collecting pool 3 and the circulation pool 30, the overflow water guide assembly 5 includes an inlet pipe 50, a drain pipe 51, a floating plate 52, a pulling cable 53 and at least one group of guide rollers 54, one end of the inlet pipe 50 and the drain pipe 51 are located in the water collecting pool 3, and the other end passes through the side wall of the water collecting pool 3 and is located in the circulation pool 30, the inlet pipe 50 is close to the bank of the water collecting pool 3, the drain pipe 51 is close to the bottom of the water collecting pool 3, and one end of the drain pipe 51 located in the circulation pool 30 is provided with a movable door 300 for closing the drain pipe 51, at least one group of guide rollers 54 is fixedly connected to the bank between the water collecting pool 3 and the circulation pool 30, one end of the pulling cable 53 is fixedly connected to the floating plate 52, and the other end is fixedly connected to the movable door 300 after passing through the guide roller 54.

[0042] When there is a long period of rainy weather or a sudden accident that causes a large amount of fire-fighting water to be used, the water intake per unit time of the water collection pool 3 will exceed its water discharge per unit time, thereby causing the water level in the water collection pool 3 to gradually rise. During this process, the floating plate 52 will move upward as the water level rises. During this process, the part of the pulling rope 53 located in the turnover pool 30 will accumulate at the bottom of the turnover pool 30. At this time, the movable door 300 is not subject to external force, and the drain pipe 51 is in a closed state. When the position of the floating plate 52 exceeds the water inlet pipe 50, a large amount of water collected in the water collection pool 3 will enter the turnover pool 30 through the water inlet pipe 50, thereby alleviating the pressure caused by excessive water collection in the water collection pool 3.

[0043] When the rainy weather or sudden accident is over, the amount of water entering the water collection pool 3 per unit time is less than its discharge amount, the water level begins to drop, and the floating plate 52 moves downward. During the downward movement, the pulling rope 53 is gradually pulled until the floating plate 52 drops to a certain height, and the pulling rope 53 is straightened. In the subsequent downward movement of the floating plate 52, the movable door 300 is pulled by the pulling rope 53 to release the closed state of the drain pipe 51, and a large amount of water in the turnover pool 30 is discharged from the drain pipe 51 to the water collection pool 3. According to the different activity modes of the movable door 300, the connection position of the pulling rope 53 is also different. For example, if the movable door 300 adopts an up and down sliding mode, the pulling rope 53 should be fixedly connected to the upper end of the movable door 300. If the movable door 300 adopts a hinged flipping mode, the pulling rope 53 should be fixedly connected to the lower end of the movable door 300. It should be noted that in order to prevent the water in the water collection pool 3 from flowing into the turnover pool 30 under normal circumstances, the above situation can be avoided by setting a one-way drain valve in the drain pipe 51.

[0044] Specifically, the upper end of the movable door 300 is hinged on the side wall of the circulation pool 30, and the lower end is in contact with the side wall of the circulation pool 30; there are many ways to install the movable door 300. For example, the drain pipe 51 can be opened and closed by moving the movable door 300 up and down along the side wall of the circulation pool 30. When the movable door 300 is hinged on the side wall of the circulation pool 30, the upper end of the movable door 300 must be hinged, otherwise the movable door 300 will not be able to complete the closing function of the drain pipe 51 when there is no force on it.

[0045] Specifically, a vertical slide rail 32 is provided on the side wall of the water collecting pool 3 close to the circulation pool 30, and at least one group of sliders 520 slidably connected to the slide rail 32 is provided on the floating plate 52; considering that the floating plate 52 may float to other positions with the water flow in the water collecting pool 3, resulting in the movable door 300 being opened when the water level in the water collecting pool 3 has not reached a predetermined height, the slide rail 32, i.e., the slider 520, is used to limit the relative position of the floating plate 52.

[0046] Embodiment 3

[0047] Please see attached Figure 6

[0048] Specifically, a floating object filtering assembly 6 is provided at the water inlet end of the sewage information detection tank 1, and the floating object filtering assembly 6 includes a filter basket 60, an inclined guide plate 61, a filter screen 62 and a mixing water truck 63. The filter basket 60 is detachably connected to the side wall of the water inlet end of the sewage information detection tank 1, the inclined guide plate 61 is located at one side of the water inlet end of the filter basket 60, and is fixedly connected to the side wall of the water inlet end of the sewage information detection tank 1, the filter screen 62 is fixedly connected to one end of the inclined guide plate 61 away from the filter basket 60, the mixing water truck 63 is located at one side of the water inlet end of the inclined guide plate 61, and is movably connected to the side wall of the water inlet end of the sewage information detection tank 1, and the mixing water truck 63 is provided with a motor matched therewith;

[0049] Considering that in the detection of floating objects, there is usually no pollution in the water quality itself, but due to the presence of floating objects, it needs to be discharged into the sewage treatment workshop 4. At the same time, some floating objects are easy to be blocked in the pipe, such as plastic bags in the living area. Some existing areas also use filter nets for filtering, but the use of the filter net is prone to floating objects blocking it, resulting in poor water flow at the water inlet end of the sewage information detection pool 1.

[0050] In view of the fact that floating objects are basically on the water surface, an inclined guide plate 61 is provided to guide the upper water flow so that it flows along the inclined guide plate 51 to the filter basket 60 behind it. At the same time, in order to prevent the floating objects from sinking to the bottom of the water during the guiding process, a filter net 62 is provided at the end of the inclined guide plate 61 away from the filter basket 60. Considering that in actual applications, the water flow rate may not be large enough, resulting in the floating objects being unable to flow into the filter basket 60 along the inclined guide plate 51, a mixing water truck 63 is provided to speed up the water flow rate near the inclined guide plate 61.

[0051] Embodiment 4

[0052] Please see attached Figure 7

[0053] The sewage information detection pool 1 is provided with a second floating object filtering assembly 7 at the water inlet end, and the second floating object filtering assembly 7 includes a collecting box body 70, at least one group of mesh L-shaped filter plates 71, at least one group of connecting rods 72 and a plurality of connecting shafts 73. The collecting box body 70 is fixedly connected to the side wall of the sewage information detection pool 1 at the water inlet end, and the plurality of connecting shafts 73 are rotatably connected to the middle position of the side wall of the collecting box body 70 and the side wall of the mesh L-shaped filter plate 71 in the vertical direction, one end of the connecting rod 72 is fixedly connected to the connecting shaft 73 on the side wall of the collecting box body 70, and the other end is fixedly connected to the connecting shaft 73 on the side wall of the mesh L-shaped filter plate 71, and rectangular contact strips 710 fixedly connected thereto are provided at both ends of the plate body of the mesh L-shaped filter plate 71 in the horizontal direction, and a vertical baffle 74 fixedly connected thereto is provided on one side wall of the water inlet end of the collecting box body 70.

[0054] Considering that the unknown water volume in some areas is small, the kinetic potential energy itself is not enough to drive the floating objects along the inclined guide plate 61 into the filter basket 60, and the mixing water truck 63 is not suitable when the water flow is small;

[0055] Therefore, a second floating object filtering assembly 7 is arranged at the water inlet end of the sewage information detection pool 1 to directly filter the floating objects. The mesh L-shaped filter plate 71 is located under the water surface. The mesh L-shaped filter plate 71 is driven by the motor to rotate along the collection box body 70. During this process, the floating objects in the water flow at the lower side of the collection box body 70 are filtered onto the mesh L-shaped filter plate 71, and in the subsequent rotation process, the mesh L-shaped filter plate 71 moves to the upper side of the collection box body 70. During the rotation process, the mesh L-shaped filter plate 71 is always vertically oriented under the action of gravity. It is in a relatively vertical downward state until it contacts the vertical baffle 74 provided on one side of the water inlet end of the collection box body 70. Since the rectangular contact strip 710 provided on the horizontal plate body of the mesh L-shaped filter plate 71 contacts the vertical baffle 74, the relative angle of the mesh L-shaped filter plate 71 changes, thereby achieving the purpose of dumping the floating objects on the horizontal plate body of the mesh L-shaped filter plate 71 from the gap between the two rectangular contact strips 710 into the collection box body 70. It should be noted that the matching motor speed in this case should not be too fast.

[0056] Specifically, the bottom wall of the collection box body 70 is a mesh structure. In order to achieve a better filtering effect, the bottom wall of the collection box body 70 adopts a mesh structure to drain the floating objects while filtering. At the same time, in order to facilitate the cleaning of the floating objects in the collection box body 70, the bottom wall of the collection box body 70 can adopt a detachable structure, such as a drawer-shaped structure.

[0057] Specifically, the connecting shaft 73 on the side wall of the collecting box body 70 is provided with a small stepping motor matched therewith; considering that some areas have less unknown and often flowing water, and correspondingly, there are fewer floating objects, a small stepping motor can be used to make the mesh L-shaped filter plate 71 stand still for a period of time below the water surface to accumulate floating objects, and then drive the mesh L-shaped filter plate 71 to rotate one circle after a certain period of time to complete the dumping of floating objects. The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, shall be covered by the protection scope of the present invention by equivalently replacing or changing the technical solution and inventive concept of the present invention.
