Description

[0001] The invention relates to the technical field of environmental sewage flow detection, and in particular to an environmental sewage flow detection device. Background Art

[0002] Environmental sewage flow detection can accurately understand the flow of sewage, which is crucial for controlling and reducing water pollution. By detecting sewage flow, the total amount of sewage entering sewage treatment facilities or discharged into the natural environment can be determined, thereby evaluating the pollution load.

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

[0031] It also includes an operating tube 2 and an installation tube 3. The detection tube 101, the operating tube 2 and the installation tube 3 are detachably connected at their ends by means of threads. A dividing component is provided inside the operating tube 2 to prevent turbulence from being generated during the sewage transportation detection process. The ultrasonic flow meter is provided inside the installation tube 3.

[0032] The segmentation component includes a mounting plate 401, a positioning groove 402 for assisting the mounting plate 401 in positioning and installation is arranged inside the operating tube 2, a plurality of groups of segmentation holes 403 for segmenting the circulating sewage are arranged on the mounting plate 401, and each group of segmentation holes 403 is arranged in a honeycomb shape, a limiting component for assisting the mounting plate 401 in positioning and limiting the position after being positioned inside the positioning groove 402 and a sealing component for sealing during the limiting process are arranged on the mounting plate 401, and an adjusting component for adjusting the sewage flow aperture on the segmentation hole 403 is arranged on one side of the mounting plate 401;

[0033] It should be noted here that: in the process of using the environmental sewage flow detection device to detect the environmental sewage flow, the dividing component inside the operating tube 2 is used to reduce the generation of turbulence during the detection process, and the channel diameter of the dividing hole 403 structure is small, which can make the water flow maintain a relatively stable laminar state in the operating tube 2, avoiding turbulence of sewage during the detection and transportation process, so that the sewage flow rate transported inside the installation tube 3 can accurately represent the average flow rate of the entire pipeline cross section, thereby ensuring the accuracy of sewage flow detection.

[0034] Preferably, the limiting assembly includes a first annular mounting groove 501 provided on the outer side of the mounting plate 401, a plurality of groups of arc-shaped limiting plates 502 are arranged inside the first annular mounting groove 501, and each group of arc-shaped limiting plates 502 are arranged in a state of an annular array inside the first annular mounting groove 501, and a pushing assembly for pushing the arc-shaped limiting plates 502 is arranged on the mounting plate 401; the pushing assembly includes a mounting cavity 701 provided 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, two ends of the push rod 703 are respectively fixed to the arc-shaped limiting plate 502 and the push plate 702, and a transmission assembly for transmitting the push plate 702 is arranged inside the mounting plate 401;

[0035] It should be noted here that: the push plate 702 and the push rod 703 are pushed by the transmission assembly. In the process of the push rod 703 being pushed, the arc-shaped limit 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 mounting disk 401 is limited after being positioned through the abutment and extrusion effect between the arc-shaped limit plate 502 and the inner wall of the operating tube 2.

[0037] It should be noted here that: during the limiting process, the interior of the annular airbag 602 is inflated through the inflation component. During the inflation process, the pressure inside the annular airbag 602 causes the annular airbag 602 to expand and press against the inner wall of the operating tube 2, thereby sealing the mounting plate 401 and the operating tube 2. Through the sealing effect, the gap between the mounting plate 401 and the operating tube 2 is prevented from affecting the pressure of the circulating air, thereby further facilitating subsequent sampling and detection 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 is communicated with the interior of the annular airbag 602, the other end of the piston tube 801 is slidably connected with a piston rod 802, and one end of the piston rod 802 is fixed to the push plate 702;

[0039] It should be noted here that: during the limiting process, the movement of the push plate 702 pushes the piston rod 802 to move toward the inside of the piston tube 801, and through the extrusion effect of the piston rod 802, part of the gas inside the piston tube 801 is squeezed and transported to the inside of the annular airbag 602, thereby inflating the inside of the annular airbag 602.

[0040] Preferably, the transmission assembly includes a circular cavity 901 centrally opened inside the mounting plate 401, the mounting cavity 701 is communicated with the circular cavity 901, a driving plate 902 is rotatably connected inside the circular cavity 901, a plurality of groups of inclined grooves 903 are opened on the driving plate 902, and a transmission pin 904 is slidably connected to each group of inclined grooves 903, a transmission plate 905 is fixed to one side of the push plate 702, one end of each group of transmission pins 904 is fixed to each group of transmission plates 905, and a first rotating assembly for rotating the driving plate 902 is arranged inside the circular cavity 901;

[0041] It should be noted here that: the driving disk 902 is rotated by the first rotating component, and during the rotation of the rotating disk 902, each group of inclined slots 903 interacts with each group of transmission pins 904, so that each group of transmission plates 905 is driven to move away from each other.

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

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

[0044] Preferably, the adjustment component 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 is provided with a plurality of adjustment holes 1102 respectively matched with the segmentation holes 403, and a second rotation component for rotating the adjustment disk 1101 is arranged between the mounting disk 401 and the adjustment disk 1101;

[0045] It should be noted here that: the adjusting disk 1101 is driven to rotate by the second rotating component. During the rotation of the adjusting disk 1101, the communication state between each group of adjusting holes 1102 and each group of dividing holes 403 is adjusted respectively, and the area of ​​communication between the adjusting holes 1102 and the dividing holes 403 is controlled. By adjusting the communication area, the circulating sewage can be divided with different flow areas during the division process. When the sewage flow rate inside the operating pipe 2 is large, the larger flow area can allow more sewage to pass through, reduce the resistance of the sewage in the honeycomb structure, and avoid the increase of local pressure and the generation of unstable flow due to excessive resistance. In this way, it can be ensured that the sewage can pass through the honeycomb structure smoothly under high flow rate and reduce the possibility of turbulence. On the contrary, when the sewage flow rate is small, the smaller flow area can make the sewage more evenly distributed in the honeycomb structure, enhance the rectification effect, and the smaller flow area can increase the contact area between the sewage and the mounting disk 401, thereby improving the stability of the fluid and reducing the vortex and irregular flow that may occur during low-speed flow.

[0046] Preferably, the second rotating assembly includes a circular groove 1201 centrally opened on the adjusting disk 1101, a gear ring 1202 is fixed inside the circular groove 1201, an L-shaped frame 1204 is fixed on one side of the mounting disk 401, the L-shaped frame 1204 is inside the circular groove 1201, a rotating shaft 1205 is rotatably connected to the L-shaped frame 1204, a gear 1203 is fixed to one end of the rotating shaft 1205, the gear 1203 and the gear ring 1202 are meshed with each other, and a second motor 1206 for driving the rotating shaft 1205 is installed on the L-shaped frame 1204;

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

[0048] In this scheme: an environmental sewage flow detection device comprises the following steps:

[0049] When using the environmental sewage flow detection device to detect the environmental sewage flow, the connection is made with the outlet of the sewage pipe through the connecting pipe 102. After the connection is completed, the installation disk 401 is positioned and installed inside the positioning groove 402 of the operating pipe 2. After the positioning and installation, the positioning and installation installation disk 401 is limited by the limiting component. After the installation and limitation of the installation disk 401, the ends of the detection pipe 101, the operating pipe 2 and the installation pipe 3 are connected end to end by means of threads;

[0050] After the various components are installed and connected, the sewage is transported through the detection tube 101 toward the inside of the operating tube 2 and the installation tube 3 through the sewage discharge pipe. In the process of the transported sewage flowing on the installation disk 401 inside the operating tube 2, since the installation disk 401 is provided with multiple groups of segmentation holes 403, and each group of segmentation holes 403 is arranged in a honeycomb shape, this structure can make the transported sewage be divided into many small water streams when passing through, thereby reducing the generation of turbulence, and the channel diameter of the segmentation hole 403 structure is small, so that the water flow in the operating tube 2 can maintain a relatively stable laminar state, avoiding turbulence of the sewage during the detection and transportation process, so that the flow rate of the sewage transported inside the installation tube 3 can accurately represent the average flow rate of the entire pipeline cross section, thereby ensuring the accuracy of the sewage flow detection, and in the process of the segmentation component segmenting the circulating sewage, the second rotating component drives the adjusting disk 1101 to rotate, and in the process of the adjusting disk 1101 rotating, The communication state between each group of regulating holes 1102 and each group of segmenting holes 403 is adjusted respectively, and the area of ​​communication between the regulating holes 1102 and the segmenting holes 403 is controlled. By adjusting the communication area, the circulating sewage can be segmented with different flow areas. When the sewage flow rate inside the operating pipe 2 is large, the larger flow area can allow more sewage to pass through, reduce the resistance of the sewage in the honeycomb structure, and avoid the increase of local pressure and the generation of unstable flow due to excessive resistance. In this way, it can be ensured that the sewage can smoothly pass through the honeycomb structure under high flow rate and reduce the possibility of turbulence. On the contrary, when the sewage flow rate is small, the smaller flow area can make the sewage more evenly distributed in the honeycomb structure, enhance the rectification effect, and the smaller flow area can 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 during low-speed flow.

[0051] During the process of installing and limiting the mounting disk 401, the mounting disk 401 is pushed into the interior of the positioning groove 402 of the operating tube 2 and abuts against the inner wall of the positioning groove 402. After the abutment is completed, the driving disk 902 is rotated by the first rotating assembly. During the rotation of the rotating disk 902, each group of inclined grooves 903 interacts with each group of transmission pins 904, respectively, so that each group of transmission plates 905 are driven to move away from each other. During the movement of the transmission plates 905, the push rod 703 is pushed by the push plate 702. During the pushing 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 opposing and squeezing effect of the inner walls limits the installation disk 401 after it is positioned. 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 effect of the piston rod 802, part of the gas inside the piston tube 801 is squeezed and transported to the inside of the annular airbag 602 to inflate the inside of the annular airbag 602. During the inflation process, the pressure inside the annular airbag 602 causes the annular airbag 602 to expand and oppose the inner wall of the operating tube 2, thereby sealing the installation disk 401 and the operating tube 2. Through the sealing effect, the gap between the installation disk 401 and the operating tube 2 is prevented from affecting the pressure of the circulating sewage, further facilitating subsequent detection operations.
