Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment equipment, specifically relating to a floc image acquisition device. Background Technology

[0002] In water treatment, coagulants and flocculants (chemical additives) are often added to the water to achieve coagulation, so that colloidal particles and tiny suspended solids in the water can aggregate and settle, thereby purifying the water.

[0003] Flocculation is a crucial step in water purification processes, and accurately controlling the flocculant dosage is key. Several major challenges exist in flocculant dosage control. First, there is a non-linear relationship: the relationship between dosage and effect is not simple linear, exhibiting saturation effects or non-linear responses. Second, the flocculation process has a significant hysteresis effect; changes in dosage do not immediately reflect in the results. Finally, the flocculation process is influenced by multiple variables, requiring consideration of their interactions and relationships.

[0004] Coagulation is a crucial step in wastewater treatment; too much or too little coagulant will prevent the water treatment from achieving the desired results. Excessive coagulant dosage not only increases production costs but can also lead to secondary pollution of water bodies and the environment. The aggregates that appear during coagulation are called flocs. Traditionally, their quantity, size, and structure are observed manually based on visual inspection and experience, and the quality of coagulation is judged accordingly. Therefore, this method is not only inefficient, lacks timeliness and accuracy, but is also costly. While underwater image acquisition devices are now used to capture floc images, current devices have limited acquisition conditions, resulting in limited accuracy in image recognition of floc images.

It should be understood that such usage can be interchanged where appropriate, and the term "comprising," and any variations thereof, is intended to cover non-exclusive inclusion.

[0024] like Figure 1-3 As shown, a flocculent flower image acquisition device is provided, including: a waterproof first light-emitting element 2, a second light-emitting element 3, an image acquisition device 1, and an adjustable connecting device.

[0025] Image acquisition device 1 can be a self-waterproof acquisition device, or a transparent and sealed shell can be placed over the outside of image acquisition device 1. The structure of image acquisition device 1 can refer to existing technology.

[0026] Image acquisition unit 1, first light source 2, and second light source 3 are all mounted on the connecting device; both the first light source 2 and second light source 3 include a frame 4, a light source 5, and a color plate 6; the light source 5 and the color plate 6 are mounted on opposite sides of the frame 4, with the color plate 6 located in the illumination area of ​​the light source 5; the light source 5 is a waterproof light source 5, or a highly transparent waterproof shell is installed on the outside of the light source 5; the frame 4 is made of waterproof material, and the color plate 6 of the first light source 2 and the color plate 6 of the second light source 3 are different colors; when the connecting device is in the first working state, image acquisition unit 1 is directly facing the second light source 3. When the connecting device is in the second working state, the image acquisition device 1 faces the color plate 6 of the second light source 3. That is, when the connecting device is in different working states, the image acquisition device 1 can acquire the alum flower image with the color plate 6 of the first light source 2 as the backing and the alum flower image with the color plate 6 of the second light source 3 as the backing respectively. The two different colored color plates 6 enable the image acquisition device 1 to acquire alum flower images with different colored backings, thereby improving the accuracy of alum flower contour feature extraction when recognizing alum flower images in the future.

[0027] In this application, the color plate 6 of the first light-emitting body 2 is white, and the color plate 6 of the second light-emitting body 3 has several independent color block regions 61, and the colors of all color block regions 61 are not exactly the same; more specifically, the second light-emitting body 3 has three color block regions 61, which are red, blue and green respectively; the three color block regions 61 of the second light-emitting body 3 are distributed in an equilateral triangle. The three color block regions 61 are all circular or other uniform shapes, and the image acquisition device 1 can capture the three color block regions 61 simultaneously.

[0028] Furthermore, the second light source 3 has several light sources 5, which are one-to-one with the color block area 61. The optical parameters of the several light sources 5 of the second light source 3 are completely consistent. The optical parameters of the light sources 5 of the second light source 3 can also be completely consistent with those of the light sources 5 of the first light source 2, or only the illumination area of ​​the light sources 5 of the first light source 2 and the second light source 3 is different, while other optical parameters are the same.

[0029] In this embodiment, the connecting device includes a horizontal connecting frame 71, a first vertical rod 72, a second vertical rod 73, and an automatic telescopic rod 74. The fixed part of the automatic telescopic rod 74 is connected to one end of the horizontal connecting frame 71, and the telescopic part of the automatic telescopic rod 74 is connected to the first vertical rod 72. The second vertical rod 73 is installed at the other end of the horizontal connecting frame 71. That is, the first vertical rod 72 and the second vertical rod 73 are arranged opposite to each other. The first vertical rod 72 and the second vertical rod 73 are also made of waterproof material. The first light-emitting element 2 and the second light-emitting element 3 are respectively located on the first vertical rod 72. When the automatic telescopic rod 74 is in a retracted or extended state, the first light-emitting element 2 faces the image acquisition device 1, or the second light-emitting element 3 faces the image acquisition device 1. In this application, the automatic telescopic rod 74 is used to switch the first light-emitting element 2 facing the image acquisition device 1 or the second light-emitting element 3 facing the image acquisition device 1. Therefore, the automatic telescopic rod 74 is usually an electric push rod with a high waterproof rating, such as IP67 or IP68. The electric push rod can realize the rapid switching of the first light-emitting element 2 and the second light-emitting element 3.

[0030] In some other embodiments, the horizontal connecting frame 71 is telescopic; that is, the horizontal connecting frame 71 can be extended or retracted by an electric telescopic rod or other automatic telescopic device to adjust the distance between the image acquisition device 1 and the light-emitting body, or the horizontal distance can be adjusted manually. Specifically, the horizontal connecting frame 71 includes a first crossbar 711, a second crossbar 712, and a connecting bolt 713; the second crossbar 712 is slidably connected inside the first crossbar 711, and the first crossbar 711 and the second crossbar 712 are square, i.e., to avoid the first crossbar 711 from being too square. The first horizontal bar 711 and the second horizontal bar 712 rotate coaxially. Both the first horizontal bar 711 and the second horizontal bar 712 have several threaded holes. The connecting bolts 713 are detachably installed in the corresponding threaded holes of the first horizontal bar 711 and the second horizontal bar 712. The second vertical bar 73 is connected to the second horizontal bar 712, and the first vertical bar 72 is connected to the first horizontal bar 711. There can be multiple connecting bolts 713, that is, each connecting bolt 713 corresponds to a set of threaded holes of the first horizontal bar 711 and the second horizontal bar 712, thereby improving the connection strength.

[0031] It is worth noting that, since the connecting device of this application can change its length both horizontally and vertically, the first and second working states of the connecting device of this application are for the retracted or extended state of the automatic telescopic rod 74. Of course, the connecting device can also have more working states to adapt to the horizontal change of the length of the connecting device. In some other embodiments, the image acquisition device 1 can also be mounted on the second vertical rod 73 by means of a rotating device such as a turntable, so as to facilitate the acquisition of multi-angle images of alum flowers.

[0032] In some other embodiments, the alum flower image acquisition device also includes a lifting device 8. The movable end of the lifting device 8 is connected to the connecting device through a connecting frame. That is, the lifting device 8 adjusts the water depth of the image acquisition device 1, so as to be able to acquire alum flower images at different depths below the water surface. The structure of the lifting device 8 can refer to the prior art, specifically, such as a small gantry crane or a screw jack.

[0033] In some other embodiments, the alum flower image acquisition device also includes a rinsing spray gun 9, which is located next to the lifting device 8. The rinsing spray gun 9 can rinse the first light source 2, the second light source 3, the image acquisition device 1, etc. The structure of the rinsing spray gun 9 is based on the prior art.

[0034] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
