Description

Technical Field

[0001] This application relates to the field of total phosphorus monitoring equipment technology, and in particular to an online total phosphorus monitor. Background Technology

[0002] Total phosphorus monitoring instruments are laboratory instruments used to monitor total phosphorus. Phosphorus in water can exist in the form of elemental phosphorus, orthophosphate, condensed sulfate, pyrophosphate, and organically combined phosphates. Its main sources are domestic sewage, fertilizers, organophosphorus pesticides, and phosphate detergents used in modern detergents. Currently, when monitoring the total phosphorus content in water bodies, it is usually necessary to take samples from multiple monitoring points in the water body. After the samples are sent to the laboratory, the total phosphorus monitoring instrument is used to monitor the total phosphorus content in the water body. The total phosphorus monitoring instrument integrates a detection chamber, a clamping mechanism for fixing the sample cups, a phosphorus sensor, and a phosphorus information transmission device. During detection, it is only necessary to connect the water samples from multiple sample cups one by one to the monitoring head of the phosphorus sensor, and the phosphorus content information in the water samples can be transmitted to the computer for statistical analysis.

[0003] However, after the test is completed, the sample cup often needs to be manually removed from the clamping mechanism and taken out of the testing room, which is a cumbersome process that is time-consuming and labor-intensive. Utility Model Content

[0004] To address the aforementioned issues, this application proposes an online total phosphorus monitor, aiming to solve the technical problem of the cumbersome and time-consuming process of manually removing test tubes from the clamping mechanism and carrying them out of the testing chamber.

[0005] To solve the above-mentioned technical problems, the technical solution of this application is as follows:

[0006] An online total phosphorus monitor includes a detection chamber and also includes:

[0007] A triangular turntable is disposed in the detection chamber, and a guide hole is provided on the triangular turntable;

[0008] A conveyor track is provided below the guide hole, with one end of the conveyor track extending to the outside of the detection chamber;

[0009] A clamping seat is fixed on the triangular turntable. A variable diameter retaining ring is provided on one side of the clamping seat. The variable diameter retaining ring is located above the guide hole and corresponds to the guide hole one by one.

[0010] Optionally, the clamping seat has a groove along its length, and a first slider and a second slider are slidably connected in the groove; the variable diameter retaining ring includes a symmetrical first half ring and a second half ring, the first half ring is connected to the outside of the first slider, and the second half ring is connected to the outside of the second slider.

[0011] Optionally, a disc is rotatably provided at the bottom of the slide groove, and two arc-shaped limiting grooves are formed on the disc. A pin is slidably connected in each arc-shaped limiting groove. One end of the pin away from the disc is connected to the inner side of the first slider, and the other end of the pin away from the disc is connected to the inner side of the second slider.

[0012] Optionally, a drive shaft is provided at the center of the disc shaft, and one end of the drive shaft extends out of the clamping seat and is connected to a geared motor.

[0013] Optionally, a rotating shaft is provided through the center of the triangular turntable, and a spur gear is fitted around the outer periphery of the rotating shaft, with the spur gear located below the triangular turntable; the spur gear is meshed with an incomplete gear.

[0014] Optionally, a mounting box for mounting spur gears and incomplete gears is provided below the triangular turntable, and the gear shaft of the incomplete gear extends into the mounting box and is connected to a drive motor for transmission.

[0015] Optionally, the detection chamber is equipped with a phosphorus-containing sensor, and a display module is provided on one side along the length of the detection chamber. The display module is electrically connected to the phosphorus-containing sensor.

[0016] Beneficial effects: When using this application, simply place the water-filled sample cup into the variable-diameter retaining ring. The retaining ring is then electrically controlled to radially contract to secure the sample cup. The rotation of the triangular turntable can move the sample cup to the detection area to complete the total phosphorus detection. After the detection is completed, the turntable continues to rotate to move the sample cup to the top of the conveyor track. The retaining ring radially expands to release the sample cup, which falls through the guide hole into the lower conveyor track. The sample cup is then automatically conveyed to the outside by the conveyor track extending to the outside of the detection room. During this process, the unloading and removal of the sample cup does not require manual intervention, thus saving time and effort. Attached Figure Description

[0027] The specific embodiments of this application will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this application and do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0028] Example 1:

[0029] See Figures 1 to 4 An online total phosphorus monitor includes a detection chamber 1, and further includes:

[0030] A triangular turntable 2 is disposed inside the detection chamber 1, and a guide hole 3 is provided on the triangular turntable 2;

[0031] A conveyor track 4 is located below the guide hole 3, and one end of the conveyor track 4 extends to the outside of the detection chamber 1;

[0032] The clamping seat 5 is fixed on the triangular turntable 2. A variable diameter retaining ring 6 is provided on one side of the clamping seat 5. The variable diameter retaining ring 6 is located above the guide hole 3 and corresponds one-to-one with the guide hole 3.

[0033] Specifically, the triangular turntable 2 is rotatably installed inside the testing chamber 1. Guide holes 3 are formed in the triangular area of ​​the turntable 2, meaning there are three guide holes 3. Correspondingly, the clamping seat 5 and the variable-diameter retaining ring 6 are also provided in three separate configurations, each corresponding to one of the three guide holes 3. The variable-diameter retaining ring 6 is used to clamp and fix the sample cup. It adjusts the clamping force by changing its inner diameter, thereby fixing or removing the sample cup. The inner diameter of the guide hole 3 is slightly larger than the diameter of the sample cup, facilitating the sample cup's passage through the guide hole 3 into the conveyor track 4. The conveyor track 4 is located below one of the guide holes 3, and a conveyor belt is laid on the conveyor track 4. One end of the conveyor track 4 extends outside the testing chamber 1, facilitating the transfer of the sample cup outside the testing chamber 1. The conveyor belt is existing technology and will not be described in detail here.

[0034] In use, the sample cup is placed inside the variable diameter retaining ring 6. The sample cup is fixed by reducing the inner diameter of the variable diameter retaining ring 6. Then, the triangular turntable 2 is driven to rotate. The triangular turntable 2 drives the clamping seat 5 and the variable diameter retaining ring 6 to rotate, thereby moving the sample cup containing water to the detection area. After the total phosphorus content in the water is detected, the triangular turntable 2 is driven again to move the tested sample to the top of the conveyor track 4. The sample cup is released by increasing the inner diameter of the variable diameter retaining ring 6. The released sample cup falls into the lower conveyor track 4 through the guide hole 3 and is then conveyed to the outside of the detection chamber 1 through the conveyor track 4.

[0035] To prevent sample spillage and tipping of the cup, a guide tube can be added to the bottom of the guide hole 3. A receiving tube matching the sample cup is also installed on the conveyor track 4, with a sponge lining to protect the cup. The released sample cup enters the receiving tube through the guide tube and is then conveyed to the outside of the detection chamber 1 via the conveyor track 4. The bottom of the guide tube should not contact the upper end of the conveyor track 4 to avoid motion interference.

[0036] In traditional techniques, after testing, the sample cup often needs to be manually removed from the clamping mechanism and taken out of the testing chamber 1, a cumbersome and time-consuming process. However, in this application, the water-filled sample cup is simply placed inside the variable-diameter retaining ring 6. Electrical control causes the retaining ring to radially contract to secure the sample cup. The rotating triangular turntable 2 moves the sample cup to the testing area to complete the total phosphorus test. After testing, the turntable continues to rotate, moving the sample cup above the conveyor track 4. The retaining ring radially expands to release the sample cup, which falls through the guide hole 3 into the lower conveyor track 4. The sample cup is then automatically conveyed to the outside by the conveyor track extending outside the testing chamber 1. During this process, the removal and unloading of the sample cup requires no manual intervention, thus saving time and effort.

[0037] In addition, to facilitate the entry of the sample cup into the testing chamber 1, an opening and closing door 7 is installed at the front end of the testing chamber 1.

[0038] Example 2:

[0039] See Figures 4 to 8 Based on the above embodiments, optionally, the clamping seat 5 has a groove along its length direction, and a first slider 8 and a second slider 9 are slidably connected in the groove; the variable diameter retaining ring 6 includes a symmetrical first half ring 10 and a second half ring 11, the first half ring 10 is connected to the outside of the first slider 8, and the second half ring 11 is connected to the outside of the second slider 9.

[0040] Specifically, the groove of the clamping seat 5 provides a directional sliding track for the first slider 8 and the second slider 9. The first slider 8 and the second slider 9 are fixedly connected to the first half ring 10 and the second half ring 11 of the variable diameter retaining ring 6, respectively. By moving the two sliders closer or further apart in the groove, the first half ring 10 and the second half ring 11 can be synchronously driven to symmetrically close or open, thereby adjusting the inner diameter of the variable diameter retaining ring 6. When the two sliders are close together, the variable diameter retaining ring 6 shrinks radially to clamp the sample cup. When the two sliders are far apart, the variable diameter retaining ring 6 expands radially to release the sample cup.

[0041] Optionally, a disc 12 is rotatably provided at the bottom of the slide groove. Two arc-shaped limiting grooves 13 are provided on the disc 12. A pin 14 is slidably connected in each arc-shaped limiting groove 13. One end of the pin 14 away from the disc 12 is connected to the inner side of the first slider 8, and the other end of the pin 14 away from the disc 12 is connected to the inner side of the second slider 9.

[0042] Specifically, when the disc 12 rotates, under the action of the arc-shaped limiting groove 13, the two pins 14 move in the two arc-shaped limiting grooves 13 respectively, thereby driving the first slider 8 and the second slider 9 to slide relatively closer or further away along the sliding groove, thereby synchronously driving the first half ring 10 and the second half ring 11 to close or open, thereby realizing the fastening or release of the sample cup.

[0043] Optionally, a drive shaft is provided at the center of the disc 12, with one end of the drive shaft extending out of the clamping seat 5 and being connected to a geared motor 15. The geared motor 15 has the characteristics of reducing speed and increasing torque, which can convert the high-speed rotation of the motor into the low-speed stable rotation required by the disc 12, and avoid the disc 12 rotating too fast, causing the retaining ring to open and close too violently.

[0044] Specifically, the drive shaft and the disc 12 are connected by a key or a pin. As the power connection component between the geared motor 15 and the disc 12, the drive shaft can accurately transmit the rotational power output by the geared motor 15 to the axis of the disc 12, thereby driving the disc 12 to rotate around the axis.

[0045] Example 3:

[0046] See Figure 3 and Figure 9Based on the above embodiments, optionally, a rotating shaft 16 is provided through the middle of the triangular turntable 2, a spur gear 17 is fitted on the outer periphery of the rotating shaft 16, and the spur gear 17 is located below the triangular turntable 2; the spur gear 17 is meshed with an incomplete gear 18.

[0047] Specifically, the rotating shaft 16 is connected to the triangular turntable 2 and the spur gear 17 via a key or pin. The incomplete gear 18 has three sets of teeth. When the teeth of the incomplete gear 18 mesh with the spur gear 17, it drives the spur gear 17 to rotate, causing the turntable to switch positions. When the toothless part of the incomplete gear 18 corresponds to the spur gear 17, the meshing is interrupted, the spur gear 17 and the turntable stop rotating, and the turntable stops at the current position. This intermittent transmission perfectly matches the three-position requirement of the triangular turntable 2. Each rotation of the incomplete gear 18 drives the spur gear 17 to rotate 120°, allowing the turntable to precisely switch one position and achieve a cyclical rhythm of rotation-stop-rotation.

[0048] Optionally, a mounting box 19 for mounting a spur gear 17 and an incomplete gear 18 is provided below the triangular turntable 2. The gear shaft of the incomplete gear 18 extends into the mounting box 19 and is connected to a drive motor 20.

[0049] Specifically, the mounting box 19 is fixed inside the testing chamber 1, and the drive motor 20 is fixed inside the mounting box 19. The drive motor 20 is connected to the gear shaft of the incomplete gear 18 through a gear transmission, providing stable power for the station switching of the triangular turntable 2: when the drive motor 20 is running, the power is transmitted to the incomplete gear 18 through the gear shaft, and the incomplete gear 18 then drives the spur gear 17 to rotate through tooth meshing, thereby realizing the intermittent rotation of the triangular turntable 2. It should be noted that the drive motor 20 is also a geared motor.

[0050] See Figure 3 Optionally, the detection chamber 1 is equipped with a phosphorus sensor, and the detection chamber 1 is provided with a display module 21 along one side of its length. The display module 21 is electrically connected to the phosphorus sensor.

[0051] Specifically, a telescopic rod 22 can be installed in the testing chamber 1, with a phosphorus-containing sensor mounted on it, to enable the sensor to be raised and lowered. The telescopic rod 22 works in conjunction with the triangular turntable 2 for station switching to avoid structural interference: when the triangular turntable 2 drives the sample cup to the testing area, the telescopic rod 22 drives the sensor to descend, allowing the monitoring head to accurately connect with the sample cup to complete the test; after the test is completed, the telescopic rod 22 first drives the sensor to rise and reset, and then allows the triangular turntable 2 to rotate to switch to the next sample cup, preventing the sensor from colliding with the rotating sample cup and the clamping seat 5, thus ensuring the safe operation of the equipment.

[0052] The display module 21 receives and presents the detection data collected by the phosphorus sensor in real time, making it convenient for operators to quickly read the detection results without manual recording or computer query. The display module 21 is also electrically connected to other electrical components, and can synchronously display the equipment operating status, including the lifting position of the phosphorus sensor, the current position of the triangular turntable 2, and the working status of the drive motor 20 and the conveyor track 4, allowing operators to monitor the equipment status in real time and troubleshoot problems in a timely manner. In addition, the display module 21 can also serve as a human-machine interface, allowing operators to set detection parameters through touch or buttons and receive feedback on the parameter setting results.

[0053] The embodiments of this application have been described in detail above with reference to the accompanying drawings, but this application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this application, and these variations still fall within the protection scope of this application.
