Abstract
Description
Technical Field
[0001] This utility model relates to the field of water body detection technology, specifically a turbidity detection device for sewage treatment. Background Technology
[0002] In existing technologies, during the wastewater treatment process, it is sometimes necessary to test the turbidity of the wastewater beforehand. The turbidity of the water body is directly related to the quality of the water and also directly affects the subsequent treatment of the water body.
[0003] For example: “A turbidity detection device and method for wastewater treatment” disclosed in Publication (Announcement) No.: CN115112757A; “A turbidity detection device for wastewater treatment” disclosed in Publication (Announcement) No.: CN104596991B; and “A method and device for continuous monitoring of water turbidity” disclosed in Publication (Announcement) No.: CN104075997B.
[0004] However, in existing technologies, water samples are usually taken directly before testing. This is problematic because, firstly, water sampling is cumbersome and requires setting up samplers; secondly, sediment may form in the water after sampling, which can lead to discrepancies in the test data and make the results inaccurate.
[0005] Therefore, in order to solve the above problems, it is necessary to develop a water turbidity detection device with a reasonable structure that can directly perform detection in water bodies. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a turbidity detection device for wastewater treatment; the technical solution is as follows:
[0007] A turbidity detection device for wastewater treatment includes a detection chamber with a steel cable at the upper end and a counterweight at the lower outer edge. A rotary motor is installed at the middle of the lower outer edge of the detection chamber, and the main shaft of the rotary motor extends upward into the detection chamber. A water inlet is provided on the lower side wall of the detection chamber. A horizontally arranged crossbar is installed on the main shaft, and a water blocking plate is installed at the end of the crossbar. The water blocking plate blocks the water inlet, and when the main shaft rotates, the water blocking plate moves and opens the water inlet.
[0008] The upper end of the detection chamber is also provided with a sealed installation chamber, in which a piston drive mechanism is installed. A piston rod is installed on the piston drive mechanism, and the piston rod extends downward into the detection chamber. A piston plate is installed at the end of the rod. The piston plate is placed inside the detection chamber and moves up and down inside the detection chamber under the action of the piston drive mechanism. Exhaust holes are also provided on both sides of the upper end of the detection chamber, and the exhaust holes are located above the piston plate.
[0009] The detection chamber has a sealed chamber on each of the two side walls in the middle of the chamber, and a turbidity detection component is installed in each of the two sealed chambers. The turbidity detection component on one side emits light into the detection chamber, and the turbidity detection component on the other side receives the light.
[0010] Furthermore, the locations on the detection chamber where the sealed chambers on both sides are set are made of transparent material, allowing light to pass through the side walls of the detection chamber and enter the chamber.
[0011] Furthermore, the upper side of the detection chamber has two exhaust ports, one on the left and one on the right; by setting exhaust ports on both sides, the gas can be discharged more smoothly.
[0012] Furthermore, a limiting plate is also provided on the inner side of the upper end of the detection box. The limiting plate is located between the exhaust port and the piston plate to limit the piston plate so that the movement height of the piston plate will not exceed the exhaust port.
[0013] Furthermore, the detection box has four water inlets at its lower end; and the crossbar is a cross-shaped structure with a water-blocking plate at each of the four ends.
[0014] Furthermore, the steel rope is also equipped with a cable core, which is used to provide power to each component and corresponding control signals to each component.
[0015] Beneficial effects: This utility model has the following beneficial effects:
[0016] 1) This device can complete the turbidity sampling of ballast water. After the whole device is placed in the water, the water inlet is opened by the rotating motor driving the crossbar and the water blocking plate. At the same time, the piston plate is moved upward by the piston drive mechanism, thereby sucking the water into the detection chamber. Then, the turbidity detection components on both sides are used for detection. The structure is reasonable and the detection effect is relatively accurate.
[0017] 2) When the piston plate of this device moves upward, it can discharge the water and air that enter from above. It is equipped with a limit plate to limit the displacement of the piston plate, and is equipped with a steel rope with a cable inside the steel rope. The structure is reasonable.
[0018] 3) This device can not only detect the turbidity of water, but also, after the detection is completed, the horizontal bar and the water blocking plate at the end of the bar can be reset by rotating the motor to reseal the water inlet. Then the whole device can be lifted out to obtain water samples. It can complete both turbidity detection and water sampling. Attached Figure Description

[0023] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a turbidity detection device for sewage treatment includes a detection chamber 1. A steel cable 2 is provided at the upper end of the detection chamber 1, and a counterweight 3 is installed at the lower outer edge of the detection chamber 1. A rotary motor 4 is installed at the middle position of the lower outer side of the detection chamber 1. The main shaft 5 of the rotary motor 4 extends upward into the detection chamber 1. A water inlet 6 is provided at the lower side wall of the detection chamber 1. A horizontally arranged crossbar 7 is installed on the main shaft 5, and a water blocking plate 8 is installed at the end of the crossbar 7. The water blocking plate 8 blocks the position of the water inlet 6. When the main shaft 5 rotates, the water blocking plate 8 moves and opens the water inlet 6.
[0025] The upper end of the detection chamber 1 is also provided with a sealed installation chamber 9. A piston drive mechanism 10 is installed in the installation chamber 9. A piston rod 11 is installed on the piston drive mechanism 10. The piston rod 11 extends downward into the detection chamber 1, and a piston plate 12 is installed at the end of the rod. The piston plate 12 is located in the detection chamber 1 and moves up and down in the detection chamber 1 under the action of the piston drive mechanism 10. The upper end of the detection chamber 1 is also provided with exhaust holes 13 on both sides, and the exhaust holes 13 are located above the piston plate 12.
[0026] A sealed chamber 14 is provided on each of the two side walls in the middle of the detection chamber 1, and a turbidity detection component 15 is provided in the sealed chamber 14 on both sides. The turbidity detection component 15 on one side emits light into the detection chamber 1, and the turbidity detection component 15 on the other side receives light.
[0027] The positions on the detection chamber 1 where the sealing chambers 14 on both sides are set are made of transparent material, so that light can pass through the side walls of the detection chamber 1 and enter the chamber.
[0028] There are two exhaust vents 13 on the upper side of the test chamber 1, one on the left and one on the right.
[0029] A limiting plate 16 is also provided on the inner side of the upper end of the detection box 1. The limiting plate 16 is located between the exhaust hole 13 and the piston plate 12 to limit the piston plate 12 so that the moving height of the piston plate 12 will not exceed the exhaust hole 13.
[0030] There are four water inlet holes 6 at the bottom of the test chamber 1; and the crossbar 7 is a cross-shaped structure, with a water blocking plate 8 at each of the four ends of the crossbar 7.
[0031] The reinforcing rope 2 also contains a cable core, which is used to provide power to each component and corresponding control signals to each component.
[0032] The working principle of this device is as follows: First, the position of the internal crossbar needs to be set accordingly. After the main shaft is rotated by the rotary motor, the water blocking plate on the crossbar will block the water inlet hole accordingly, and the piston plate above will descend to the lowest position under the action of the piston drive mechanism.
[0033] The detection box is then lowered into the water using a counterweight and a steel cable. A scale can be set on the steel cable to lower it to the specified depth. Under the action of the counterweight, the detection box sinks into the water. During the sinking process, water may enter through the vent at the top, but this will not affect the detection of the device.
[0034] When the entire device descends to the designated depth, the rotary motor is activated, the main shaft drives the crossbar to rotate, and the crossbar drives the end-mounted water-blocking plate to open the water inlet. Then, the piston drive mechanism is activated, driving the piston plate to move upward, gradually drawing water into the detection chamber through the water inlet. As the piston plate rises, it gradually expels water and air from the upper space through the exhaust port into the detection chamber until the piston plate moves upward to the position of the limit plate, at which point the detection chamber is filled with water.
[0035] Then, the turbidity of the water in the test chamber can be detected by the turbidity detection components on both sides. Since the turbidity detection components need to emit light, the corresponding positions of the test chamber and the corresponding positions of the sealed chamber need to be transparent to detect the turbidity of the water.
[0036] Furthermore, during the testing process, since the water is drawn into the testing chamber, impurities in the water will not precipitate, resulting in more accurate testing. After the testing is completed, the horizontal bar can be rotated by a rotary motor, which will cause the water-blocking plate at the end of the bar to seal the water inlet. Then, the entire device can be pulled out of the water to complete the sampling work. It can perform both turbidity testing and water sampling.
[0037] The above-described specific embodiments are merely preferred embodiments of this utility model and are not intended to limit the implementation of this utility model or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
