Description

Technical Field

[0001] This utility model relates to the technical field of wastewater testing and sampling equipment, specifically to a wastewater sampling device for wastewater treatment. Background Technology

[0002] In polluted waters, precise remediation requires analyzing the pollutant components. This typically involves using sampling devices to collect samples for further analysis. However, most existing sampling devices only perform single samples at a time, while pollutants are likely distributed in strata. Therefore, multiple samplings are often necessary, which is not only cumbersome but can also affect sample accuracy due to varying sampling times.

[0003] To this end, Chinese Patent No. CN223307934U discloses a wastewater testing sampling device. After the lifting pipe is submerged into the water area by the lifting component, the water inlet outside the inlet pipe is allowed to enter the lifting pipe by the control and adjustment of the sliding adjustment component, so that the water can enter the sampling tube. By setting multiple sampling tubes, water samples at different depths can be collected at one time.

[0004] However, existing sampling devices require the use of electromagnets to control the opening and closing of the cover. However, electromagnets are easily affected by moisture, which can cause them to fail to open and close smoothly. Outdoor sampling environments are different, so a more adaptable sampling device is needed. Utility Model Content

[0005] To address the aforementioned problems, a wastewater sampling device for wastewater treatment is provided. The device solves the technical problem of electromagnets being susceptible to short-circuit failure due to water vapor in wastewater by using the transmission cooperation between the control rod and the opening and closing mechanism.

[0006] To address the problems of existing technologies, this utility model provides a wastewater sampling device for wastewater treatment, comprising a main rod, support rods, and an opening and closing mechanism; a control rod is slidably installed inside the main rod, and the axis of the control rod is collinear with the axis of the main rod; at least two support rods are provided, each support rod is provided with a sampling bottle for holding the sample, and the sampling bottle is provided with a cap; the opening and closing mechanism is used to control the opening and closing of the cap, and the opening and closing mechanism is connected to the control rod in a transmission manner.

[0007] Preferably, the opening and closing mechanism includes a connecting frame and a transmission assembly; the connecting frame is slidably mounted on the support rod, and the cover is connected to the connecting frame; the connecting frame is connected to the cover via the transmission assembly.

[0008] Preferably, the transmission assembly includes a mounting plate, a connecting ring, and a first elastic element; the mounting plate is slidably disposed on the main rod and is connected to the control rod; the connecting ring is slidably disposed on the control rod; and the two ends of the first elastic element are respectively connected to the connecting ring and the connecting frame.

[0009] Preferably, the sampling bottle is detachably mounted on the support rod, and the sampling bottle is provided with a retaining plate and a protrusion on the retaining plate; the end of the support rod away from the main rod is provided with an end seat, and the end seat is provided with a side plate, and the side plate is provided with a groove that cooperates with the protrusion.

[0010] Preferably, a movable seat is slidably mounted on the end seat, and a second elastic element is provided on the movable seat. The two ends of the second elastic element are respectively connected to the movable seat and the end seat. When the protrusion on the card plate is inserted into the card slot, the movable seat abuts against the card plate under the elastic force of the second elastic element.

[0011] Preferably, the support rod is rotatably connected to the main rod; the main rod is provided with a limiting ring that is rotatably connected to the support rod.

[0013] Preferably, the top of the control lever is connected to a top rod, and the top of the top rod is provided with a grip for holding.

[0014] The advantages of this utility model compared to the prior art are: 1. This utility model achieves synchronous opening and closing control of multiple sampling bottle caps through the transmission cooperation between the control rod and the opening and closing mechanism. It adopts a mechanical transmission method for opening and closing the caps, which overcomes the reliability defects of traditional electromagnet drives in sewage environments and solves the technical problem that electromagnets are easily affected by water vapor in sewage and fail due to short circuits.

[0015] 2. This utility model enhances the synchronicity and stability of the cap's opening and closing through an opening and closing mechanism composed of a connecting frame and a transmission assembly. During operation, the control rod slides, causing the connecting frame to move synchronously along the support rod. The connecting frame transmits power to the cap through the transmission assembly: when the connecting frame moves upward, the transmission assembly drives the cap to open, allowing wastewater to enter the sampling bottle; when the connecting frame moves downward, the transmission assembly drives the cap to close, sealing the sample. This structure ensures that the caps of all sampling bottles are controlled in conjunction with the same connecting frame, guaranteeing completely synchronized opening and closing actions. This avoids inconsistencies in sampling time due to individual differences. Combined with the reliability of the mechanical transmission, it eliminates the risk of electromagnet short circuits while further improving the consistency and accuracy of multi-bottle sampling.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-3 A wastewater sampling device for wastewater treatment includes a main rod 1, a support rod 2, and an opening and closing mechanism 3. A control rod 11 is slidably installed inside the main rod 1, and the axis of the control rod 11 is collinear with the axis of the main rod 1. At least two support rods 2 are provided, and each support rod 2 is provided with a sampling bottle 21 for holding the sample, and the sampling bottle 21 is provided with a cap 211. The opening and closing mechanism 3 is used to control the opening and closing of the cap 211, and the opening and closing mechanism 3 is connected to the control rod 11 in a transmission manner.

[0027] This invention achieves synchronous opening and closing control of the caps 211 of multiple sampling bottles 21 through the transmission cooperation between the control rod 11 and the opening and closing mechanism 3. The mechanical transmission method overcomes the reliability defects of traditional electromagnet drives in wastewater environments and solves the technical problem of electromagnets being susceptible to short-circuit failure due to water vapor in wastewater. During operation, the operator manually slides the control rod 11 within the main rod 1, which, through the mechanical linkage of the opening and closing mechanism 3, directly drives the caps 211 of all sampling bottles 21 to move synchronously: when lowering the device, the control rod 11 drives the opening and closing mechanism 3 to close the caps 211, preventing wastewater from entering prematurely; after reaching the sampling depth, the control rod 11 is slid in the opposite direction, and the opening and closing mechanism 3 drives the caps 211 to open, completing the sampling; before removal, the control rod 11 is slid again to close the caps 211. This mechanical control method requires no electric drive, completely eliminating the risk of short circuits and poor contact of electromagnets in humid environments. It is not limited by cable or battery power supply and can operate stably in complex sewage environments. Combined with the multi-rod design, it not only ensures sampling efficiency but also improves the durability and operational flexibility of the device.

[0028] Reference Figures 1-3 The opening and closing mechanism 3 includes a connecting frame 31 and a transmission assembly 32; the connecting frame 31 is slidably mounted on the support rod 2, and the cover 211 is connected to the connecting frame 31; the connecting frame 31 is connected to the cover 211 through the transmission assembly 32.

[0029] This invention enhances the synchronicity and stability of the opening and closing of the cap 211 through the opening and closing mechanism 3 composed of the connecting frame 31 and the transmission component 32. During operation, the control rod 11 slides, causing the connecting frame 31 to move synchronously along the support rod 2. The connecting frame 31 transmits power to the cap 211 through the transmission component 32: when the connecting frame 31 moves upward, the transmission component 32 drives the cap 211 to open, allowing wastewater to enter the sampling bottle 21; when the connecting frame 31 moves downward, the transmission component 32 drives the cap 211 to close, sealing the sample. This structure ensures that the caps 211 of all sampling bottles 21 are linked and controlled by the same connecting frame 31, guaranteeing completely synchronized opening and closing actions. This avoids inconsistent sampling times due to individual differences. Combined with the reliability of the mechanical transmission, it eliminates the risk of electromagnet short circuits while further improving the consistency and accuracy of multi-bottle sampling.

[0030] Reference Figures 1-3 The transmission assembly 32 includes a mounting plate 321, a connecting ring 322, and a first elastic element 323; the mounting plate 321 is slidably disposed on the main rod 1 and is connected to the control rod 11; the connecting ring 322 is slidably disposed on the control rod 11; the two ends of the first elastic element 323 are respectively connected to the connecting ring 322 and the connecting frame 31.

[0031] This invention achieves buffered adjustment of the opening and closing of the cover 211 through a transmission assembly 32 containing a first elastic element 323, thus controlling the opening and closing of the cover 211 and solving the technical problem of excessive rigidity in mechanical transmission causing easy damage to the cover 211 or connecting parts. The bottom of the connecting ring 322 has a protrusion that cooperates with the support rod 2. During operation, the control rod 11 slides, causing the mounting plate 321 to move. The connecting ring 322 compresses the first elastic element 323, and the power is transmitted to the connecting frame 31. When the control rod 11 moves upward, the mounting plate 321 pushes the connecting ring 322 to compress the first elastic element 323. The elastic force drives the connecting plate upward through the connecting frame 31, and the transmission assembly 32 drives the cover 211 to open slowly. When the control rod 11 moves downward, the first elastic element 323 resets, pushing the connecting ring 322 to reset, and the connecting plate moves downward, causing the cover 211 to close slowly. The buffering effect of the first elastic element 323 prevents rigid impact during the opening and closing of the cap 211, reducing component wear. Simultaneously, the elastic force of the first elastic element 323 controls the automatic closing of the cap 211, preventing sample leakage or contamination after sampling. Combined with the reliability of the mechanical transmission, this eliminates the risk of electromagnet short circuits, extends the device's lifespan, and ensures long-term stable operation for multi-bottle sampling.

[0032] Reference Figure 2 , Figures 4-6 The sampling bottle 21 is detachably mounted on the support rod 2. The sampling bottle 21 is provided with a retaining plate 212 and a protrusion 2121. The end of the support rod 2 away from the main rod 1 is provided with an end seat 22. The end seat 22 is provided with a side plate 221 and a groove 2211 that cooperates with the protrusion 2121 is opened on the side plate 221.

[0033] This invention achieves a quick and detachable connection of the sampling bottle 21 through the insertion and engagement of the protrusion 2121 and the slot 2211, solving the technical problem of time-consuming installation and removal and reduced sampling efficiency caused by the complex installation structure of traditional sampling bottles 21. The end seat 22 has an inlet for the sample to flow into the sampling bottle 21. During installation, the operator aligns the sampling bottle 21 with the bottom of the end seat 22, misaligns the retaining plate 212 with the edge plate 221, and pushes it into the end seat 22. Once the retaining plate 212 moves above the edge plate 221, the sampling bottle 21 is rotated until the protrusion 2121 aligns with the slot 2211. Finally, the protrusion 2121 and the slot 2211 are inserted and engaged to complete the installation. Disassembly is performed by reversing the operation. This structure allows for tool-free loading and unloading of the sampling bottle 21, making operation simple and quick. Combined with the mechanically driven cap 211 control, it eliminates the risk of electromagnet short circuits while significantly improving the efficiency of sample transfer and cleaning / replacing the sampling bottle 21 after sampling, meeting the needs of frequent sampling at wastewater treatment sites. During sampling, pulling the control lever 11 opens the cap 211 via the opening / closing mechanism 3, allowing wastewater to flow into the sampling bottle 21 through the inlet for sampling.

[0034] Reference Figure 2 and Figure 4 A movable seat 23 is slidably mounted on the end seat 22. The movable seat 23 is provided with a second elastic element 231. The two ends of the second elastic element 231 are connected to the movable seat 23 and the end seat 22 respectively. When the protrusion 2121 on the card plate 212 is inserted into the card slot 2211, the movable seat 23 abuts against the card plate 212 under the elastic force of the second elastic element 231.

[0035] This invention solves the technical problem of the protrusion 2121 separating from the slot 2211 due to shaking during sampling by using the elastic force of the second elastic element 231 to keep the movable seat 23 continuously abutting against the locking plate 212. When installing the sampling bottle 21, when the protrusion 2121 is inserted into the slot 2211, the movable seat 23 pushes the locking plate 212 upward under the elastic force of the second elastic element 231, so that the protrusion 2121 is tightly embedded in the slot 2211, forming an axial limit. During the sampling process, no matter how the device shakes, the second elastic element 231 always maintains the abutment force against the locking plate 212, preventing the protrusion 2121 from falling out of the slot 2211. This structure adds an anti-loosening function on the basis of quick installation and removal. Combined with the mechanical transmission of the cap 211, it not only retains the convenience of replacing the sampling bottle 21, but also ensures the reliability of the connection during sampling, avoiding sample spillage or device damage.

[0036] Reference Figure 1 and Figure 7 Support rod 2 is rotatably connected to main rod 1; main rod 1 is provided with a limiting ring 12 that is rotatably connected to support rod 2.

[0037] This invention solves the technical problem of the inability of traditional fixed support rods 2 to flexibly adjust the sampling position by means of the rotatable connection between the support rod 2 and the main rod 1 and the limiting effect of the limiting ring 12. The device includes a main rod 1, a support rod 2, and an opening and closing mechanism 3. A control rod 11 is slidably installed inside the main rod 1. A sampling bottle 21 with a cover 211 is provided on the support rod 2. The support rod 2 is rotatably connected to the main rod 1, and the limiting ring 12 is rotatably connected to the support rod 2 on the main rod 1. During operation, the operator can rotate the support rod 2 to adjust the orientation angle of the sampling bottle 21. The limiting ring 12 rotates synchronously with the support rod 2 and limits its excessive swing, ensuring that the sampling bottle 21 is stably in the target position. After adjustment, the opening and closing mechanism 3 is driven by the control rod 11 to realize the synchronous opening and closing of the cover 211, completing the sampling of sewage from different angles or areas. This structure enables the device to adapt to the sampling needs of different positions in complex sewage environments. Combined with the mechanical transmission control of the cover 211 and the anti-electromagnetic short-circuit design, it improves the sampling flexibility while maintaining operational reliability and stability.

[0038] Reference Figure 1 and Figure 7 The limiting ring 12 is provided with an anti-slip groove 121 to increase the friction between the support rod 2 and the limiting ring 12.

[0039] This invention enhances the frictional resistance between the support rod 2 and the limiting ring 12 by using an anti-slip groove 121 on the limiting ring 12, thus solving the technical problem that the support rod 2 is prone to displacement due to external force or its own weight after the angle is adjusted. During operation, the operator rotates the support rod 2 to adjust the sampling angle. The anti-slip groove 121 increases the frictional force of the contact surface, ensuring that the support rod 2 remains stably in the adjusted position when no external force is applied, preventing angle displacement due to device shaking or water flow impact during sampling. After determining the angle, the opening and closing mechanism 3 is driven by the control rod 11 to complete the sampling. The design of the anti-slip groove 121 enhances the reliability of angle fixation based on the rotatable adjustment of the support rod 2. Combined with the mechanically driven cover 211 control and the anti-electromagnetic short-circuit structure, it further improves the accuracy and stability of sampling in complex wastewater environments.

[0040] Reference Figure 1 and Figure 7 The top of the control lever 11 is connected to a top rod 111, and the top of the top rod 111 is provided with a grip 1111 for holding.

[0041] This invention optimizes the operating structure of the control lever 11 by configuring the top rod 111 and the handle 1111, solving the technical problems of inconvenient force application and easy slippage when directly operating the control lever 11. During operation, the operator grips the handle 1111 to move the top rod 111 up and down, thereby driving the control lever 11 to slide along the main rod 1: when the handle 1111 is lifted, the top rod 111 moves the control lever 11 upwards, opening the sampling bottle 21 cap 211 via the opening and closing mechanism 3; when the handle 1111 is pressed down, the control lever 11 moves downwards, closing the cap 211. The handle 1111 provides a comfortable force application point, making the sliding operation of the control lever 11 more effortless and stable, avoiding inaccurate opening and closing timing of the cap 211 due to hand slippage. Combined with the reliability of the mechanical transmission, this further improves the accuracy and convenience of sampling operations, making it particularly suitable for scenarios involving long-term or frequent operations at wastewater sampling sites.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
