Description

Technical Field

[0001] This disclosure relates to the technical field of wastewater treatment, and in particular to a wastewater pool water quality testing organization and a water pollutant testing device. Background Technology

[0002] In municipal engineering projects, sewage tanks primarily store domestic wastewater, which typically contains a large amount of organic matter. This organic matter ferments in the sewage tank, producing water pollutants such as organic acids and nutrients. To facilitate subsequent treatment of domestic wastewater, water quality testing is usually required before treatment. For details, please refer to [link to relevant documentation]. Figure 1 Most manufacturers typically use water quality testing equipment to directly test wastewater in the sewage tank. According to testing standards, the probe of the water quality testing equipment needs to be inserted a predetermined distance below the liquid level in the sewage tank. However, due to the changes in the amount of domestic wastewater treated in the sewage tank, the distance the probe of the water quality testing equipment is inserted below the liquid level in the sewage tank will change. This means that the probe of the water quality testing equipment needs to be manually checked or adjusted each time, which causes inconvenience in use. Utility Model Content

[0003] The purpose of this disclosure is to overcome the shortcomings of the prior art and to provide a wastewater tank water quality testing mechanism and a water pollutant testing device that can keep the water quality testing probe at a predetermined position below the liquid level in the wastewater tank.

[0004] A wastewater treatment plant water quality testing facility, comprising:

[0005] A wall-mounted bracket, which is used to be fixedly installed on the side wall of the sewage tank;

[0006] A water quality testing probe, used to detect pollutants in water bodies;

[0007] The wastewater tank water quality testing mechanism also includes a fixed outer rod, a telescopic inner support rod, a liquid level float assembly, and a push-pull drive assembly.

[0008] The fixed outer sleeve is fixedly installed on the wall-mounted bracket, and the telescopic inner support rod is partially slidably disposed within the fixed outer sleeve. The water quality detection probe is installed at the bottom end of the telescopic inner support rod and is positioned below the liquid level of the sewage tank. The liquid level float assembly is used to float above the liquid level of the sewage tank to detect the liquid level. The push-pull drive assembly is fixedly disposed at the top end of the fixed outer sleeve, and the push-pull part of the push-pull drive assembly is fixedly connected to the telescopic inner support rod. The push-pull drive assembly is electrically connected to the sensing unit of the liquid level float assembly, and the push-pull drive assembly is used to drive the telescopic inner support rod to move according to the liquid level value measured by the liquid level float assembly, so that the water quality detection probe rises or falls.

[0009] In some embodiments, the liquid level buoy assembly includes a buoyancy ring and a liquid level sensor; the buoyancy ring is slidably sleeved on the outside of the telescopic inner support rod and is used to float on the liquid level of the sewage tank; the liquid level sensor is mounted on the buoyancy ring and electrically connected to the push-pull drive assembly.

[0010] In some embodiments, the push-pull drive assembly includes a motor, a rotating shaft, and a connecting cylinder; the motor is fixedly mounted on the top end of the fixed outer sleeve rod, and the rotating shaft is disposed inside the fixed outer sleeve rod; the connecting cylinder is located inside the telescopic inner support rod, and the outer peripheral wall of the connecting cylinder is threadedly connected to the inner peripheral wall of the telescopic inner support rod; the first end of the rotating shaft is fixedly connected to the drive shaft of the motor, and the second end of the rotating shaft is fixedly connected to the connecting cylinder; the motor is electrically connected to the liquid level float assembly.

[0011] In some embodiments, an external thread is formed on the outer peripheral wall of the connecting cylinder, and an internal thread is formed on the inner wall of the telescopic inner support rod; the external thread engages with the internal thread to drive the telescopic inner support rod to rise and fall when the connecting cylinder rotates.

[0012] In some embodiments, an anti-rotation guide groove is formed on the inner wall of the fixed outer sleeve rod, and the anti-rotation guide groove extends along the length direction of the fixed outer sleeve rod; a guide block is protruding from the outer wall of the telescopic inner support rod into the anti-rotation guide groove, and the guide block slides against the groove wall of the anti-rotation guide groove.

[0013] In some embodiments, the top of the motor is covered with a rain cap.

[0014] In some embodiments, the water quality detection probe is a pH probe or a salinity probe; and / or,

[0015] The water quality detection probe is located at least 0.3m below the liquid level in the wastewater tank.

[0016] In some embodiments, the wastewater tank water quality testing mechanism further includes a digital display box, which is electrically connected to the push-pull drive assembly.

[0017] In some embodiments, the digital display box has a grounding electrode.

[0018] A water pollutant detection device includes a wastewater pool water quality testing mechanism according to any of the above embodiments.

[0019] Compared with the prior art, this disclosure has at least the following advantages:

[0020] In the aforementioned wastewater tank water quality testing mechanism, the telescopic inner support rod is slidably mounted within the fixed outer support rod. A push-pull drive assembly, fixed to the top of the fixed outer support rod, is fixedly connected to the telescopic inner support rod. This allows the inner support rod to slide relative to the fixed outer support rod, enabling the water quality testing probe mounted at the bottom of the inner support rod to rise or fall. Simultaneously, since the push-pull drive assembly is electrically connected to the sensing unit of the liquid level float assembly, it can drive the inner support rod to move and rise or fall below the liquid level in the wastewater tank based on the liquid level value measured by the liquid level float assembly, i.e., the liquid level height of the wastewater tank. This keeps the water quality testing probe at a predetermined position below the wastewater tank liquid level. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0037] Please see Figure 2 One embodiment of a wastewater tank water quality testing mechanism includes a wall-mounted bracket 100, a water quality testing probe 200, a fixed outer sleeve rod 300, a telescopic inner support rod 400, a liquid level float assembly 500, and a push-pull drive assembly 600. The wall-mounted bracket 100 is used for fixed installation on the side wall of the wastewater tank. The water quality testing probe 200 is used for detecting water pollutants. The fixed outer sleeve rod 300 is fixedly installed on the wall-mounted bracket 100, and the telescopic inner support rod 400 is partially slidably disposed within the fixed outer sleeve rod 300. The water quality testing probe 200 is installed at the bottom end of the telescopic inner support rod 400. The water quality detection probe 200 is positioned below the liquid level in the sewage tank. A liquid level buoy assembly 500 is floated above the liquid level in the sewage tank to detect the liquid level. A push-pull drive assembly 600 is fixedly mounted on the top of the fixed outer sleeve rod 300, and the push-pull portion of the push-pull drive assembly 600 is fixedly connected to the telescopic inner support rod 400. The push-pull drive assembly 600 is electrically connected to the sensing unit of the liquid level buoy assembly 500, and is used to drive the telescopic inner support rod 400 to move according to the liquid level value measured by the liquid level buoy assembly 500, so that the water quality detection probe 200 rises or falls. The depth H of the water quality detection probe 200 below the liquid level in the sewage tank is at least 0.3m to meet the detection standards.

[0038] It is understandable that, since the telescopic inner support rod 400 is partially slidably disposed within the fixed outer support rod 300, and the push-pull drive assembly 600 fixed to the top of the fixed outer support rod 300 is fixedly connected to the telescopic inner support rod 400, the push-pull drive assembly 600 can drive the telescopic inner support rod 400 to slide relative to the fixed outer support rod 300, so that the water quality detection probe 200 installed at the bottom of the telescopic inner support rod 400 can rise or fall. Simultaneously, since the push-pull drive assembly 600 is electrically connected to the sensing unit of the liquid level float assembly 500, the push-pull drive assembly 600 can drive the telescopic inner support rod 400 to move and rise or fall below the liquid level in the sewage tank according to the liquid level value measured by the liquid level float assembly 500, i.e., the liquid level height of the sewage tank, so that the water quality detection probe 200 is maintained at a predetermined position below the liquid level in the sewage tank.

[0039] Please see Figure 2 In some embodiments, the liquid level buoy assembly 500 includes a buoyancy ring 510 and a liquid level sensor (not shown). The buoyancy ring 510 is slidably sleeved on the outside of the telescopic inner support rod 400 and is used to float on the liquid level of the sewage tank. The liquid level sensor is installed on the buoyancy ring 510 and electrically connected to the push-pull drive assembly 600. It can be understood that because the buoyancy ring 510 is slidably sleeved on the outside of the telescopic inner support rod 400, when the buoyancy ring 510 is floated on the liquid level of the sewage tank, it can rise or fall synchronously with the liquid level of the sewage tank. The liquid level sensor installed on the buoyancy ring 510 can also move with the buoyancy ring 510 to detect the liquid level value of the sewage tank in real time and send the liquid level value to the push-pull drive assembly 600. The buoyancy ring 510 is an air ring; after the buoyancy ring 510 is slidably sleeved on the outside of the telescopic inner support rod 400, the buoyancy ring 510 is less likely to drift away with domestic wastewater.

[0040] It should be noted that the method by which the liquid level sensor sends the liquid level value to the push-pull drive assembly 600 is prior art and will not be described in detail, nor is it within the scope of protection of this application. The liquid level sensor can be a traditional laser liquid level sensor or a traditional ultrasonic liquid level sensor, and will not be described in detail. In this embodiment, the sound wave emitting end of the ultrasonic liquid level sensor is oriented towards the wall-mounted bracket 100 so that the rise or fall value of the buoyancy ring 510 can be obtained by reflecting the sound wave, thereby reflecting the change in the liquid level of the sewage tank.

[0041] Please see Figure 2In some embodiments, the push-pull drive assembly 600 includes a motor 610, a rotating shaft 620, and a connecting cylinder 630; the motor 610 is fixedly mounted on the top end of the fixed outer sleeve rod 300, and the rotating shaft 620 is disposed inside the fixed outer sleeve rod 300; the connecting cylinder 630 is located inside the telescopic inner support rod 400, and the outer peripheral wall of the connecting cylinder 630 is threadedly connected to the inner peripheral wall of the telescopic inner support rod 400; the first end of the rotating shaft 620 is fixedly connected to the drive shaft of the motor 610, and the second end of the rotating shaft 620 is fixedly connected to the connecting cylinder 630; the motor 610 is electrically connected to the liquid level float assembly 500. It is understood that, since the fixed outer sleeve 300 is slidably sleeved on the telescopic inner support rod 400, the outer peripheral wall of the connecting cylinder 630 is threadedly connected to the inner peripheral wall of the telescopic inner support rod 400, and the drive shaft of the motor 610 fixedly installed at the top of the fixed outer sleeve 300 is fixedly connected to the connecting cylinder 630 through the rotating shaft 620, the motor 610 can drive the connecting cylinder 630 to rotate, thereby causing the telescopic inner support rod 400 to rise or fall. In some other embodiments, the push-pull drive assembly 600 may also be a cylinder or a hydraulic cylinder, etc., which is not limited here.

[0042] Please see Figure 2 and Figure 3 In some embodiments, an external thread is formed on the outer peripheral wall of the connecting cylinder 630, and an internal thread is formed on the inner wall of the telescopic inner support rod 400; the external thread engages with the internal thread to drive the telescopic inner support rod 400 to rise and fall when the connecting cylinder 630 rotates. It can be understood that the external thread formed on the outer peripheral wall of the connecting cylinder 630 engages with the internal thread formed on the inner wall of the telescopic inner support rod 400, enabling the motor 610 to drive the connecting cylinder 630 to rotate, thereby raising or lowering the telescopic inner support rod 400.

[0043] Please see Figure 3 In some embodiments, an anti-rotation guide groove 301 is formed on the inner wall of the fixed outer sleeve rod 300, extending along the length of the fixed outer sleeve rod 300; a guide block 410 protrudes from the outer wall of the telescopic inner support rod 400 into the anti-rotation guide groove 301, and the guide block 410 slides against the groove wall of the anti-rotation guide groove 301. It can be understood that because the guide block 410 on the outer wall of the telescopic inner support rod 400 slides against the groove wall of the anti-rotation guide groove 301, and the anti-rotation guide groove 301 extends along the length of the fixed outer sleeve rod 300, the guide block 410 can guide the telescopic inner support rod 400 to move along the length of the fixed outer sleeve rod 300, while preventing the telescopic inner support rod 400 from rotating axially within the fixed outer sleeve rod 300.

[0044] Please see Figure 2In some embodiments, the top of the motor 610 is covered with a rain cap 640. It is understood that by covering the top of the motor 610 with a rain cap 640, the impact of rain on the motor 610 can be reduced.

[0045] Please see Figure 2 In some embodiments, the water quality detection probe 200 is a pH probe or a salinity probe. It is understood that a pH probe can detect the content of organic acids in domestic wastewater in a sewage treatment plant, and a salinity probe can detect the content of nutrients in domestic wastewater in a sewage treatment plant.

[0046] Please see Figure 2 In some embodiments, the wastewater treatment tank water quality testing mechanism further includes a digital display box 700, which is electrically connected to the push-pull drive assembly 600. It is understood that since the digital display box 700 is electrically connected to the push-pull drive assembly 600, the push-pull distance of the push-pull drive assembly 600 can be obtained through the digital display box 700.

[0047] Please see Figure 2 In some embodiments, the digital display box 700 has a grounding electrode 710. It is understood that because the digital display box 700 has a grounding electrode 710, grounding the grounding electrode 710 can prevent lightning from affecting the use of the digital display box 700.

[0048] Please see Figures 2 to 3 A water pollutant detection device includes a wastewater tank water quality detection mechanism according to any of the above embodiments. It is understood that by applying the wastewater tank water quality detection mechanism of this application to a water pollutant detection device, since the telescopic inner support rod 400 is slidably disposed within the fixed outer support rod 300, and the push-pull drive assembly 600 fixed to the top of the fixed outer support rod 300 is fixedly connected to the telescopic inner support rod 400, the push-pull drive assembly 600 can drive the telescopic inner support rod 400 to slide relative to the fixed outer support rod 300, so that the water quality detection probe 200 installed at the bottom of the telescopic inner support rod 400 can rise or fall. Simultaneously, since the push-pull drive assembly 600 is electrically connected to the sensing unit of the liquid level float assembly 500, the push-pull drive assembly 600 can drive the telescopic inner support rod 400 to move and rise or fall below the liquid level of the wastewater tank according to the liquid level value measured by the liquid level float assembly 500, i.e., the liquid level height of the wastewater tank, so that the water quality detection probe 200 is maintained at a predetermined position below the liquid level of the wastewater tank.

[0049] Compared with the prior art, this disclosure has at least the following advantages:

[0050] In the aforementioned wastewater treatment water quality testing mechanism, the telescopic inner support rod 400 is slidably disposed within the fixed outer support rod 300. A push-pull drive assembly 600, fixed to the top of the fixed outer support rod 300, is fixedly connected to the telescopic inner support rod 400. This allows the telescopic inner support rod 400 to slide relative to the fixed outer support rod 300 via the push-pull drive assembly 600, enabling the water quality testing probe 200, installed at the bottom of the telescopic inner support rod 400, to rise or fall. Simultaneously, since the push-pull drive assembly 600 is electrically connected to the sensing unit of the liquid level float assembly 500, the push-pull drive assembly 600 can drive the telescopic inner support rod 400 to move and rise or fall below the liquid level in the wastewater treatment tank based on the liquid level value measured by the liquid level float assembly 500, i.e., the liquid level height of the wastewater treatment tank. This keeps the water quality testing probe 200 at a predetermined position below the liquid level in the wastewater treatment tank.

[0051] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
