Description

Technical Field

[0001] This invention relates to the field of environmental wastewater flow detection technology, specifically to an environmental wastewater flow detection device. Background Technology

[0002] Wastewater flow monitoring can accurately determine the flow rate of wastewater, which is crucial for controlling and reducing water pollution. By monitoring wastewater flow, the total amount of wastewater entering wastewater treatment facilities or being discharged into the natural environment can be determined, thereby assessing the pollution load. This helps environmental protection departments formulate reasonable pollution control strategies, such as adjusting the treatment capacity of wastewater treatment plants and strengthening the supervision of key pollution sources, to ensure that wastewater is effectively treated and reduce its negative impact on the environment.

[0003] During the process of detecting the flow rate of environmental sewage using an environmental sewage flow detection device, the flow velocity of sewage in the pipeline is unstable. Sudden acceleration or deceleration can easily cause turbulence. The presence of turbulence inside the pipeline will make the flow velocity distribution of sewage uneven, causing the flow velocity measured by the flow detection device to not accurately represent the average flow velocity of the entire pipeline cross-section. This will cause errors in the flow measurement results and reduce the accuracy of the measurement. To address this, we propose an environmental sewage flow detection device. Summary of the Invention

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] Please see Figures 1-9 The illustrated environmental wastewater flow detection device includes a detection pipe 101 for conveying wastewater and an ultrasonic flow meter for detecting the flow rate of the conveyed wastewater. A connecting pipe 102 for detachable installation to the sewage pipe is fixed to the front side of the detection pipe 101 via a thread.

[0030] It is worth noting here that ultrasonic flow meters, as a conventional technical means for detecting sewage flow, are considered prior art in this application and will not be described further here.

[0031] It also includes an operating pipe 2 and an installation pipe 3. The beginning and end of the detection pipe 101, the operating pipe 2 and the installation pipe 3 are detachably connected by threads. The operating pipe 2 is equipped with a dividing component to prevent turbulence during sewage transport detection. The ultrasonic flow meter is installed inside the installation pipe 3.

[0032] The dividing assembly includes a mounting plate 401. The operating tube 2 has a positioning groove 402 inside to assist in the positioning and installation of the mounting plate 401. The mounting plate 401 has multiple sets of dividing holes 403 for dividing the flowing sewage, and each set of dividing holes 403 is arranged in a honeycomb pattern. The mounting plate 401 is provided with a limiting component for limiting the mounting plate 401 after it is positioned inside the positioning groove 402, and a sealing component for sealing during the limiting process. One side of the mounting plate 401 is provided with an adjusting component for adjusting the sewage flow diameter on the dividing holes 403.

[0033] It should be noted that during the process of detecting the flow rate of environmental sewage using the environmental sewage flow detection device, the division component inside the operating pipe 2 reduces the generation of turbulence during the detection process. Furthermore, the small diameter of the channel of the division hole 403 structure allows the water flow to maintain a relatively stable laminar flow state within the operating pipe 2, avoiding turbulence in the sewage during the detection and transportation process. This ensures that the sewage flow velocity transported inside the installation pipe 3 accurately represents the average flow velocity of the entire pipe cross-section, guaranteeing the accuracy of sewage flow detection.

[0034] Preferably, the limiting component includes a first annular mounting groove 501 opened on the outside of the mounting plate 401. The first annular mounting groove 501 is provided with multiple sets of arc-shaped limiting plates 502, and the arc-shaped limiting plates 502 are arranged in a ring array inside the first annular mounting groove 501. The mounting plate 401 is provided with a pushing component for pushing the arc-shaped limiting plates 502. The pushing component includes a mounting cavity 701 opened inside the mounting plate 401. A push plate 702 is slidably connected inside the mounting cavity 701. A push rod 703 is slidably connected between the mounting cavity 701 and the first annular mounting groove 501. The two ends of the push rod 703 are fixed to the arc-shaped limiting plate 502 and the push plate 702 respectively. The mounting plate 401 is provided with a transmission component for driving the push plate 702.

[0035] It should be noted here that: the push plate 702 and the push rod 703 are pushed by the transmission component. During the process of the push rod 703 being pushed, the arc-shaped limiting plate 502 at one end of the push rod 703 moves out from the first annular mounting groove 501 and abuts against the inner wall of the operating tube 2. Through the pressing action of the arc-shaped limiting plate 502 against the inner wall of the operating tube 2, the mounting plate 401 after being positioned is limited.

[0036] Preferably, two sets of sealing components are provided, and the two sets of sealing components are symmetrically arranged on both sides of the limiting component. The sealing component includes a second annular mounting groove 601 opened on the outside of the mounting plate 401. An annular airbag 602 is installed inside the second annular mounting groove 601, and an inflation component for inflating the annular airbag 602 is provided inside the mounting cavity 701.

[0037] It should be noted that during the limiting process, the annular airbag 602 is inflated by the inflation component. During inflation, the pressure inside the annular airbag 602 causes it to expand and press against the inner wall of the operating tube 2, sealing the mounting plate 401 and the operating tube 2. This sealing prevents the gap between the mounting plate 401 and the operating tube 2 from affecting the pressure of the circulating air, further facilitating subsequent sampling and testing operations.

[0038] Preferably, the inflation assembly includes a piston tube 801 fixed between the second annular mounting groove 601 and the mounting cavity 701. One end of the piston tube 801 communicates with the interior of the annular airbag 602, and the other end of the piston tube 801 is slidably connected to a piston rod 802. One end of the piston rod 802 is fixed to the push plate 702.

[0039] It should be noted that during the limiting process, the movement of the push plate 702 pushes the piston rod 802 toward the inside of the piston tube 801. Through the squeezing action of the piston rod 802, some of the gas inside the piston tube 801 is squeezed and transported to the inside of the annular airbag 602, thus inflating the inside of the annular airbag 602.

[0040] Preferably, the transmission assembly includes a circular cavity 901 centrally located inside the mounting plate 401, the mounting cavity 701 communicating with the circular cavity 901, a drive plate 902 rotatably connected inside the circular cavity 901, a plurality of inclined grooves 903 formed on the drive plate 902, a transmission pin 904 slidably connected to each set of inclined grooves 903, a transmission plate 905 fixed on one side of the push plate 702, one end of each set of transmission pins 904 fixed to each set of transmission plates 905, and a first rotating assembly for rotating the drive plate 902 is provided inside the circular cavity 901.

[0041] It should be noted here that: the drive disk 902 is rotated by the first rotating component. During the rotation of the drive disk 902, the interaction between each set of inclined grooves 903 and each set of transmission pins 904 drives each set of transmission plates 905 to move away from each other.

[0042] Preferably, the first rotating assembly includes a mounting bracket 1001 fixed inside the circular cavity 901, a mounting shaft 1002 rotatably connected to the mounting bracket 1001, a drive disk 902 centrally fixed to the mounting shaft 1002, and a first motor 1003 for driving the mounting shaft 1002 mounted on the mounting bracket 1001.

[0043] It should be noted that the first motor 1003 drives the mounting shaft 1002 to rotate, and during the rotation of the mounting shaft 1002, the drive disk 902 is driven to rotate.

[0044] Preferably, the adjustment assembly includes an adjustment disk 1101 rotatably connected to one side of the mounting disk 401. The adjustment disk 1101 and the mounting disk 401 are concentrically arranged. The adjustment disk 1101 has multiple sets of adjustment holes 1102 that are respectively matched with the dividing holes 403. A second rotation assembly for rotating the adjustment disk 1101 is provided between the mounting disk 401 and the adjustment disk 1101.

[0045] It should be noted that the second rotating component drives the regulating disk 1101 to rotate. During the rotation of the regulating disk 1101, the communication state between each group of regulating holes 1102 and each group of dividing holes 403 is adjusted, controlling the communication area between the regulating holes 1102 and the dividing holes 403. By adjusting the communication area, the sewage can be divided with different flow areas during the process of dividing the flow. When the sewage flow rate inside the operating pipe 2 is large, a larger flow area allows more sewage to pass through, reducing the resistance of sewage in the honeycomb structure and avoiding the generation of local pressure increase and unstable flow due to excessive resistance. This ensures that sewage can pass through the honeycomb structure smoothly at high flow rates, reducing the possibility of turbulence. Conversely, when the sewage flow rate is small, a smaller flow area allows the sewage to be distributed more evenly in the honeycomb structure, enhancing the rectification effect. The smaller flow area also increases the contact area between the sewage and the mounting disk 401, thereby improving the stability of the fluid and reducing the vortices and irregular flow that may occur during low-speed flow.

[0046] Preferably, the second rotating assembly includes a circular groove 1201 centrally located on the adjusting plate 1101, a gear ring 1202 fixed inside the circular groove 1201, an L-shaped frame 1204 fixed on one side of the mounting plate 401, the L-shaped frame 1204 being located inside the circular groove 1201, a rotating shaft 1205 rotatably connected to the L-shaped frame 1204, a gear 1203 fixed at one end of the rotating shaft 1205, the gear 1203 meshing with the gear ring 1202, and a second motor 1206 for driving the rotating shaft 1205 mounted on the L-shaped frame 1204.

[0047] It should be noted that the second motor 1206 drives the gear 1203 on the rotating shaft 1205 to rotate. During the rotation of the gear 1203, the adjusting disk 1101 is driven to rotate by the meshing transmission between the gear 1203 and the gear ring 1202.

[0048] This solution includes an environmental wastewater flow detection device, comprising the following steps:

[0049] During the process of detecting the flow rate of environmental sewage using the environmental sewage flow detection device, the connection pipe 102 is installed and connected to the outlet of the sewage pipe. After the connection is completed, the installation plate 401 is positioned and installed inside the positioning groove 402 of the operating pipe 2. After the positioning and installation, the installation plate 401 is limited by the limiting component. After the installation plate 401 is installed and limited, the ends of the detection pipe 101, the operating pipe 2 and the installation pipe 3 are connected end to end by thread.

[0050] After all components are installed and connected, sewage is transported through the drain pipe, via the detection pipe 101, towards the operating pipe 2 and the installation pipe 3. As the sewage flows through the installation plate 401 inside the operating pipe 2, multiple sets of dividing holes 403 are formed in a honeycomb pattern on the installation plate 401. This structure divides the sewage into many small water streams, reducing turbulence. Furthermore, the small diameter of the dividing holes 403 helps maintain a relatively stable laminar flow within the operating pipe 2, preventing turbulence during transport. This ensures that the sewage flow velocity inside the installation pipe 3 accurately represents the average velocity of the entire pipe cross-section, guaranteeing accurate sewage flow detection. During the process of dividing the flowing sewage, the second rotating component drives the regulating plate 1101 to rotate. The communication state between each group of regulating holes 1102 and each group of dividing holes 403 is adjusted to control the communication area between the regulating holes 1102 and the dividing holes 403. By adjusting the communication area, the sewage can be divided with different flow areas during the process of dividing the flow. When the sewage flow rate inside the operating pipe 2 is large, the larger flow area allows more sewage to pass through, reducing the resistance of sewage in the honeycomb structure and avoiding the generation of local pressure increase and unstable flow due to excessive resistance. This ensures that the sewage can pass through the honeycomb structure smoothly at high flow rates, reducing the possibility of turbulence. Conversely, when the sewage flow rate is small, the smaller flow area allows the sewage to be distributed more evenly in the honeycomb structure, enhancing the rectification effect. The smaller flow area can also increase the contact area between the sewage and the mounting plate 401, thereby improving the stability of the fluid and reducing the vortex and irregular flow that may occur at low speeds.

[0051] During the installation and positioning of the mounting plate 401, the mounting plate 401 is pushed into the positioning groove 402 of the operating tube 2 and abuts against the inner wall of the positioning groove 402. After abutting, the drive plate 902 is rotated by the first rotating component. During the rotation of the drive plate 902, the interaction between each set of inclined grooves 903 and each set of transmission pins 904 drives each set of transmission plates 905 to move away from each other. During the movement of the transmission plates 905, the push plate 702 pushes the push rod 703. During the push of the push rod 703, the arc-shaped limiting plate 502 at one end of the push rod 703 moves out from the first annular mounting groove 501 and abuts against the inner wall of the operating tube 2. The pressing action of the inner walls limits the positioning of the mounting plate 401. During the limiting process, the movement of the push plate 702 pushes the piston rod 802 toward the inside of the piston tube 801. Through the pressing action of the piston rod 802, some of the gas inside the piston tube 801 is squeezed and transported to the inside of the annular air bladder 602, inflating the inside of the annular air bladder 602. During the inflation process, the pressure inside the annular air bladder 602 causes it to expand and press against the inner wall of the operating tube 2, sealing the mounting plate 401 and the operating tube 2. Through the sealing action, the gap between the mounting plate 401 and the operating tube 2 is prevented from affecting the pressure of the flowing sewage, further facilitating subsequent testing operations.
