Description

Technical Field

[0001] This invention relates to the field of water quality monitoring technology, specifically to a biochemical wastewater quality monitoring device. Background Technology

[0002] To ensure that the discharge indicators of wastewater from biochemical plants meet the standards, it is necessary to monitor pollutant parameters through water quality monitoring devices. Existing wastewater quality monitoring devices typically integrate multiple sensors (such as pH sensors, conductivity sensors, ORP sensors, turbidity sensors, and dissolved oxygen sensors) on their monitoring probes to achieve synchronous and real-time monitoring of key water quality parameters.

[0003] However, in existing technologies, because the monitoring probe needs to be immersed in sewage for extended periods, a perforated protective cover is used to protect it from damage caused by large solid particles (such as sand, metal fragments, plastic shards, and glass shards). While this effectively protects the probe, the holes in the cover are prone to clogging. Clogging affects the amount of sewage flowing through the probe, hindering monitoring. Furthermore, sewage contains suspended particulate matter, crystalline salts, and metal precipitates, which can enter the protective cover through the holes and adhere to the probe surface. This adhesion reduces the probe's sensitivity, preventing it from meeting monitoring requirements. To address these issues, this invention proposes a biological and chemical wastewater quality monitoring device. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a biological and chemical wastewater quality monitoring device that can clean the impurities in the water passage holes of the protective cover protecting the probe while cleaning the attachments on the outside of the monitoring probe, thus ensuring the normal operation of the monitoring probe.

[0005] To achieve the above objectives, the present invention provides a biological and chemical wastewater quality monitoring device to solve the problems mentioned in the background art.

[0006] This invention is achieved through the following technical solution: A wastewater quality monitoring device for biochemical industries, comprising: A columnar monitoring probe; The protective cover includes a top plate and multiple side plates. The side plates are pivotally connected to the top plate and together with the top plate, they enclose a mounting space. The monitoring probe is located within the mounting space and fixed to the top plate. Water passage holes are provided at the joints of adjacent side plates. A first elastic element is configured to provide an elastic preload force that encloses the plurality of top plates together; A cleaning brush structure, which is ring-shaped and fitted around the monitoring probe, is movably connected to the multiple side plates via connecting rods; and The spray structure is configured to intermittently spray high-pressure liquid onto the cleaning brush structure.

[0007] Optionally, the cleaning brush structure includes an annular fixed seat and an annular rotating seat that are rotatably connected to each other. The connecting rod is connected between the annular fixed seat and the side plate. A first bristle is fixedly arranged on the inner side of the annular rotating seat, and a blade is arranged on the side of the annular rotating seat facing the spray structure.

[0008] Optionally, the side of the annular rotating seat facing the spray structure is a concave conical structure, and the blade is disposed on the conical structure.

[0009] Optionally, the annular fixed seat is provided with an annular protrusion with a circular cross-section, and the annular rotating seat is provided with an annular recess that matches the shape of the annular protrusion. The annular fixed seat is rotatably connected to the annular rotating seat through the cooperation of the annular protrusion and the annular recess.

[0010] Optionally, the cleaning brush structure further includes a brush plate, which is pivotally connected to the bottom of the annular rotating seat. The brush plate is provided with second bristles, and a second elastic element is provided between the brush plate and the annular rotating seat. The second elastic element is configured to provide an elastic preload force for the brush plate to flip toward the monitoring probe side.

[0011] Optionally, the second elastic element is a torsion spring disposed at the pivot position between the brush plate and the annular rotating seat.

[0012] Optionally, the side plate is an isosceles triangle structure, and the base of the side plate is pivotally connected to the top plate.

[0013] Optionally, the first elastic element is an elastic ring that clamps the top corners of the plurality of top plates together.

[0014] Optionally, the monitoring probe is connected to the top plate via a threaded connection.

[0015] Optionally, the spray structure includes a spray chamber and a connecting pipe. The spray chamber is opened on the top plate, and the spray nozzle of the spray chamber is aligned with the cleaning brush structure in the axial direction of the monitoring probe. One end of the connecting pipe is connected to the spray chamber, and the other end is connected to a high-pressure water source.

[0016] Compared with the prior art, the present invention provides a biological and chemical wastewater quality monitoring device, which has the following beneficial effects: 1. This invention, through a protective cover, a first elastic element, a cleaning brush structure, and a spraying structure, intermittently sprays high-pressure liquid onto the cleaning brush structure during water quality monitoring. With the coordinated action of the first elastic element and the connecting rod, on the one hand, the cleaning brush structure moves along the surface of the monitoring probe, scraping away any adhering substances and maintaining the probe's high sensitivity. On the other hand, multiple side plates of the protective cover simultaneously flip outwards, increasing the gap at the joint of adjacent side plates, allowing impurities stuck in the water passage holes to fall off. This ensures that wastewater can smoothly enter the installation space through the water passage holes and be monitored by the probe. Furthermore, when multiple side plates flip outwards simultaneously, a discharge port is formed at the bottom of the protective cover. Impurities cleaned from the probe surface can be discharged from the installation space through this port, preventing them from re-adhering to the probe under the influence of water flow, further ensuring the probe's cleanliness. 2. The cleaning brush structure of the present invention includes an annular fixed seat and an annular rotating seat that are rotatably connected to each other. A first brush bristle is fixedly arranged on the inner side of the annular rotating seat. When the spray structure sprays high-pressure liquid onto the blade, it can not only make the annular fixed seat and the annular rotating seat of the cleaning brush structure move along the axial direction of the monitoring probe, but also drive the annular rotating seat to rotate relative to the annular fixed seat, so that the first brush bristle can brush the monitoring probe in the axial and circumferential directions, thereby improving the cleaning effect on the monitoring probe. 3. By incorporating a conical structure, this invention guides most of the high-pressure liquid towards the inner side of the annular rotating seat when high-pressure liquid is sprayed onto the blades. This creates a downward water flow within the annular rotating seat, which promptly washes away impurities brushed off by the first brush bristles, further improving the cleaning effect. 4. The cleaning brush structure of the present invention also includes a brush plate, which can clean not only the side wall of the monitoring probe, but also the bottom end face of the monitoring probe, thereby realizing the cleaning of multiple surfaces of the monitoring probe.

Detailed Implementation

[0019] 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.

[0020] Example: Please refer to Figures 1 to 7 According to an embodiment of the present invention, a biochemical wastewater quality monitoring device is provided, which may include a columnar monitoring probe 100, a protective cover 200, a first elastic element, a cleaning brush structure 400, and a spray structure 500. The monitoring probe 100 is used to detect various parameters in the biochemical wastewater. For example, the monitoring probe 100 may integrate various sensors, including but not limited to pH sensors, conductivity sensors, ORP sensors, turbidity sensors, and dissolved oxygen sensors. The protective cover 200 includes a top plate 210 and multiple side plates 220, which are pivotally connected to the top plate 210 and together with the top plate 210 to form a mounting space. The monitoring probe 100 is located within the mounting space and fixed to the top plate 210. The protective cover 200, formed by the top plate 210 and the multiple side plates 220, can protect the monitoring probe 100 from the impact of large particulate solid impurities in the wastewater, thereby achieving the effect of protecting the monitoring probe 100. A water passage hole 230 is provided at the joint of adjacent side plates 220. Figures 1 to 4As shown, a row of water passage holes 230 can be provided at the joint of each group of adjacent side plates 220. The shape of the water passage holes 230 can be circular, elliptical or other geometric shapes. The diameter of the water passage holes 230 can be specifically set according to the size of large solid particles in the sewage. The function of the water passage holes 230 is to connect the installation space with the outside, prevent large solid particles in the sewage from entering the installation space, and at the same time ensure that the sewage can smoothly enter the installation space and be detected by the monitoring probe 100. The first elastic element is configured to provide elastic pre-tightening force to enclose multiple top plates 210 together. The cleaning brush structure 400 is annular and sleeved on the outside of the monitoring probe 100. The cleaning brush structure 400 and multiple side plates 220 are movably connected by connecting rods 700. The spray structure 500 is configured to intermittently spray high-pressure liquid onto the cleaning brush structure 400, thereby applying intermittent axial force to the cleaning brush structure 400.

[0021] The biochemical wastewater quality monitoring device with the above-described structure is used by placing the device in the wastewater to be monitored. Multiple sensors on the monitoring probe 100 monitor various parameters in the wastewater. The protective cover 200 protects the monitoring probe 100 from impacts by large solid particles in the wastewater, extending its service life. Water passage holes 230 on the protective cover 200 ensure that wastewater can smoothly enter the installation space and be monitored by the monitoring probe 100. During monitoring, the following situations may occur: Because the wastewater may contain impurities of similar size to the water passage holes 230, these impurities may become stuck at the holes, preventing the wastewater from smoothly entering the installation space and being monitored by the probe 100. Simultaneously, small particles in the wastewater may enter the installation space through the water passage holes 230 of the protective cover 200 and form deposits on the surface of the monitoring probe 100, thus reducing the sensitivity of the monitoring probe 100 and failing to meet monitoring requirements. If the above situation occurs, high-pressure liquid (such as clean water) can be intermittently sprayed onto the cleaning brush structure 400 by the spray structure 500. With the cooperation of the first elastic element and the connecting rod 700, on the one hand, the cleaning brush structure 400 will move along the surface of the monitoring probe 100 and clean the adhering substances on the surface of the monitoring probe 100 by scraping, so as to maintain the high sensitivity of the monitoring probe 100. On the other hand, multiple side plates 220 of the protective cover 200 will flip outward at the same time, and the gap at the joint of the adjacent side plates 220 will increase, thereby causing the impurities stuck in the water passage 230 to fall off, ensuring that the sewage can smoothly enter the installation space through the water passage 230 and be monitored by the monitoring probe 100. In addition, when multiple side plates 220 flip outward at the same time, a discharge port will be formed at the bottom of the protective cover 200. The impurities cleaned from the surface of the monitoring probe 100 can be discharged from the installation space through the discharge port to prevent these impurities from re-adhering to the monitoring probe 100 under the action of the water flow.

[0022] like Figure 5 and Figure 6 As shown, in some embodiments, the cleaning brush structure 400 includes an annular fixed seat 410 and an annular rotating seat 420 rotatably connected to each other, and a connecting rod 700 is connected between the annular fixed seat 410 and the side plate 220, as shown. Figure 4 As shown, the two ends of the connecting rod 700 can be pivotally connected to the annular fixed seat 410 and the side plate 220 respectively via pins. A first bristle 430 is fixedly provided on the inner side of the annular rotating seat 420, as shown... Figure 6 As shown, a ring of first bristles 430 can be arranged along the inner hole of the annular rotating seat 420. The first bristles 430 can be made of nylon, and the free ends of the bristles are attached to the surface of the monitoring probe 100. A blade 440 is provided on the side of the annular rotating seat 420 facing the spray structure 500, as shown... Figure 5 As shown, multiple triangular blades 440 can be arranged around the circumference of the annular rotating seat 420. The blades 440 are inclined, and the multiple blades 440 and the annular rotating seat 420 constitute an impeller structure.

[0023] By setting the cleaning brush structure 400 as described above, when the spray structure 500 sprays high-pressure liquid onto the blade 440, not only can the annular fixed seat 410 and the annular rotating seat 420 of the cleaning brush structure 400 move along the axial direction of the monitoring probe 100, but the annular rotating seat 420 can also be driven to rotate relative to the annular fixed seat 410, so that the first bristles 430 can brush the monitoring probe 100 in both the axial and circumferential directions, thereby improving the cleaning effect on the monitoring probe 100.

[0024] like Figure 5 As shown, in some embodiments, the side of the annular rotating seat 420 facing the spray structure 500 is a concave conical structure 421, and blades 440 are disposed on the conical structure 421. The blades 440 can be welded onto the conical structure 421. By providing the conical structure 421, when high-pressure liquid is sprayed onto the blades 440 on the conical structure 421, the conical structure 421 will guide most of the high-pressure liquid toward the inner side of the annular rotating seat 420, thereby forming a downward water flow inside the annular rotating seat 420. This water flow washes away the impurities brushed off by the first brush bristles 430 in a timely manner, further improving the cleaning effect.

[0025] like Figure 5 and Figure 6As shown, in some embodiments, the annular fixed seat 410 is provided with an annular protrusion 411 with a circular cross-section, and the annular rotating seat 420 is provided with an annular recess 422 that matches the shape of the annular protrusion 411. The annular fixed seat 410 is rotatably connected to the annular rotating seat 420 through the cooperation of the annular protrusion 411 and the annular recess 422. In other embodiments, the annular fixed seat 410 and the annular rotating seat 420 can also be rotatably connected by bearings.

[0026] In some embodiments, the cleaning brush structure 400 further includes a brush plate 450, which is pivotally connected to the bottom of the annular rotating seat 420, such as... Figure 5 and Figure 6 As shown, two brush plates 450 can be provided, symmetrically arranged on both sides of the bottom of the annular rotating seat 420. The brush plates 450 and the annular rotating seat 420 can be pivotally connected by a pin. The brush plates 450 are provided with second bristles 460, and a second elastic element is provided between the brush plates 450 and the annular rotating seat 420. The second elastic element is configured to provide an elastic preload force for the brush plates 450 to flip toward the monitoring probe 100. With this configuration, when the monitoring probe 100 passes between the two brush plates 450, the side of the brush plate 450 with the second bristles 460 will adhere to the side wall of the monitoring probe 100 under the elastic force of the second elastic element, and move together with the annular rotating seat 420 to clean the side wall of the monitoring probe 100. When the annular rotating seat 420 moves to the bottom of the monitoring probe 100 under the impact of high-pressure liquid, the brush plate 450 will flip under the elastic force of the second elastic element. After flipping, the side of the brush plate 450 with the second bristles 460 will adhere to the bottom end face of the monitoring probe 100. At this time, the brush plate 450 will rotate together with the annular rotating seat 420 to clean the impurities attached to the bottom end face of the monitoring probe 100. Thus, the cleaning brush structure 400 of this embodiment can not only clean the side wall of the monitoring probe 100, but also clean the bottom end face of the monitoring probe 100, thereby realizing the cleaning of multiple surfaces of the monitoring probe 100.

[0027] like Figure 5 and Figure 6 As shown, in some embodiments, the second elastic element is a torsion spring 600 located at the pivot position between the brush plate 450 and the annular rotating seat 420. In other embodiments, the second elastic element may also be a spring hinge.

[0028] like Figure 1 As shown, in some embodiments, the side plate 220 is an isosceles triangle structure, and the bottom edge of the side plate 220 is pivotally connected to the top plate 210. The side plate 220 and the top plate 210 can be pivotally connected by a pin.

[0029] like Figure 1As shown, in some embodiments, the first elastic element is an elastic ring 300 that clamps the top corners of multiple top plates 210 together. Specifically, the elastic ring 300 can be a rubber ring, and a notch 221 can be provided at the top corner of the multiple top plates 210, with the elastic ring 300 clamped at the notch 221.

[0030] like Figure 2 and Figure 4 As shown, in some embodiments, the monitoring probe 100 is connected to the top plate 210 by a threaded connection. This facilitates the disassembly and replacement of the monitoring probe 100.

[0031] like Figure 2 and Figure 4 As shown, in some embodiments, the spray structure 500 includes a spray chamber 510 and a connecting pipe 520. The spray chamber 510 is located on the top plate 210, and the spray nozzle 511 of the spray chamber 510 is aligned axially with the cleaning brush structure 400 along the monitoring probe 100. One end of the connecting pipe 520 is connected to the spray chamber 510, and the other end is connected to a high-pressure water source. The high-pressure water source can be water pressurized by a water pump, and the water pressure can be controlled by a valve. Through the spray structure 500 described above, high-pressure liquid can be intermittently sprayed onto the cleaning brush structure 400, thereby providing intermittent axial force to the cleaning brush. Of course, as long as high-pressure liquid can be intermittently sprayed onto the cleaning brush structure 400, this embodiment does not have any particular limitations on the specific structural form of the spray structure 500.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
