Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling, in particular to a sampling device used for sewage prevention and treatment. Background Art

[0002] In sewage prevention and control work, sampling devices play a vital role. They can accurately and efficiently collect sewage samples, providing a solid data foundation for subsequent analysis and treatment processes.

[0003] However, currently widely used sampling devices still present some design and practical problems, particularly when the sampling chamber, drive device, and opening and closing device are integrated. While this integrated design may simplify the overall structure, it also presents numerous drawbacks in practical use, particularly regarding maintenance and parts replacement.

[0004] First, because the sampling chamber, drive device, and opening and closing device are tightly connected to form an integrated structure, if any of these components fails or is damaged, the entire system may need to be disassembled for repair. This not only greatly increases the difficulty of repairs, but may also extend the maintenance cycle, adversely affecting the normal progress of sewage treatment work.

[0005] Secondly, the integrated design increases the need for specialized skills and tools during maintenance, which undoubtedly raises the barrier to entry and the cost of repairs. For many wastewater treatment facilities, specialized maintenance personnel or the appropriate tools may not be readily available, further exacerbating the difficulties of repairs.

[0006] Finally, if a critical component of the sampling device is damaged, and that component is closely connected to the entire device, in actual operation, the entire device may have to be replaced instead of just the damaged component. This is not only a huge waste of resources, but also increases the operating costs of the sewage treatment facility and reduces the overall economic benefits. Utility Model Content

[0007] The main purpose of the utility model is to provide a sampling device for sewage prevention and treatment, which can effectively solve the problems raised in the background technology.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A sampling device for sewage prevention and control, comprising a sampling tank, a pipe mouth of the sampling tank being connected to a valve via a connector, and a side wall of the valve being provided with a liquid suction port for sampling, an assembly frame being provided on the connector and the liquid suction port, an assembly head being provided at both ends of the assembly frame, a T-shaped mounting bar being connected to the assembly head via a mounting piece, a stepping motor being provided at the upper end of the T-shaped mounting bar, an output end of the stepping motor being connected to a hexagonal column, a docking seat being provided at the upper end of the valve, and a hexagonal hole being provided at the upper end of the docking seat that matches the hexagonal column, the docking seat and the hexagonal column being provided to achieve rapid disassembly of the stepping motor and the valve;

[0010] The hexagonal column is inserted into the hexagonal hole, and the docking seat is driven to rotate by a stepping motor to realize the opening and closing of the valve. The opening and closing of the valve is used to realize the liquid in and out of the suction port to realize sewage sampling of the sampling tank.

[0011] The connector, valve and liquid suction port are designed as one body, and the valve is a ball valve. The connector is connected to the sampling tank through a thread, and a sealing ring is provided at the connection between the connector and the sampling tank.

[0012] The rotating rod of the valve is connected to the docking seat, and the side wall protrusion of the docking seat is stuck in the annular groove of the valve, and the hexagonal column is fixed to the stepping motor by welding;

[0013] The assembly head and the assembly frame are designed as one body, and the cross section of the assembly head is in a "Z" shape. Two opposite assembly heads are located at both ends of the assembly frame. The mounting parts are divided into screws, nuts and washers. The screw passes through the assembly head and the anti-slip rubber strip and is fixed to the assembly head through the nut and the washer. The screw passes through the T-shaped mounting strip to open a waist hole and is fixed through the nut and the washer.

[0014] Among them, multiple assembly racks are composed of assembly heads and mounting parts to achieve the expansion of the number of sampling tanks. Anti-slip rubber strips are provided between the assembly heads. The number of sampling tanks is consistent with the number of stepper motors.

[0015] Among them, a main control box is installed on the upper ends of the multiple T-shaped mounting strips, and the stepper motor is installed in the main control box. The integrated circuit board of the stepper motor is placed in the main control box, and the outer wall of the main control box is provided with a hanging hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this utility model, the sampling mechanism achieves automated control through the ingenious connection of a stepper motor and a valve, significantly improving sampling efficiency. The precise control of the stepper motor ensures the accuracy of the valve opening and closing, effectively avoiding the errors that may be introduced by manual operation, making the sampling process more reliable.

[0018] The integrated design allows for a tight fit between the connector, valve, and aspiration port, enhancing the stability of the entire device. This design not only ensures stability during sampling but also reduces the risk of loose or falling components, improving device safety.

[0019] The valve adopts a ball valve design, ensuring tightness when closed, effectively preventing sewage leakage. At the same time, the connector and sampling tank are connected by a threaded connection and equipped with a sealing ring, further enhancing the sealing effect and ensuring the safety and reliability of the sampling process.

[0020] Through the clever combination of the assembly frame and assembly head, this sampling device can easily adapt to various complex environments and achieve fixation in different positions.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0028] In the field of sewage treatment, we have proposed an innovative sampling device, the detailed structure and design of which are described as follows. Figures 1 to 4As shown, the device mainly includes a sampling tank 14, the pipe mouth of which is cleverly connected to the valve 8 through a connector 13. It is worth noting that a liquid suction port 7 for sampling is specially designed on the side wall of the valve 8, which makes the sampling process more convenient.

[0029] To further enhance the stability and maintainability of the device, an assembly rack 4 was installed between the connector 13 and the liquid aspiration port 7. Assembly heads 5 are located at each end of this rack 4, tightly connected to the T-shaped mounting bar 2 via mounting members 3. A stepper motor 11 is mounted on the top end of the T-shaped mounting bar 2, with a hexagonal prism 12 connected to its output.

[0030] A docking seat 9 is provided at the upper end of the valve 8, and a hexagonal hole 10 is provided at the upper end of the docking seat 9, which perfectly matches the hexagonal column 12. This design enables the stepper motor 11 to be quickly disassembled and assembled with the valve 8, greatly improving work efficiency.

[0031] In actual use, we only need to insert the hexagonal column 12 into the hexagonal hole 10, and then drive the docking seat 9 to rotate through the stepper motor 11. In this way, the valve 8 can achieve rapid opening and closing actions, thereby controlling the inflow and outflow of liquid from the suction port 7, thereby achieving sewage sampling work in the sampling tank 14.

[0032] Furthermore, the connector 13, valve 8, and suction port 7 utilize an integrated design, resulting in a compact structure and enhanced stability. Valve 8 utilizes a ball valve design for ease of operation and durability. The connector 13 and sampling tank 14 are threaded together, ensuring a tight connection. A sealing ring is also provided at the joint to prevent wastewater leakage.

[0033] The rotating rod of valve 8 is tightly connected to docking station 9, with the protrusion on the side wall of docking station 9 cleverly snapping into the annular groove of valve 8, ensuring a stable connection between the two. The hexagonal column 12 is welded to the stepper motor 11, ensuring reliable transmission.

[0034] The assembly head 5 and assembly frame 4 also feature an integrated design. The assembly head 5 has a Z-shaped cross-section, making it more stable and easier to install. Two opposing assembly heads 5 are located at either end of the assembly frame 4. The mounting components 3, consisting of a screw, nut, and gasket, pass through the assembly head 5 and the non-slip rubber strip 6 and are secured to the assembly head 5 via the nut and gasket. Furthermore, the screw passes through a waist hole in the T-shaped mounting strip 2 and is secured via a nut and gasket, ensuring the stability of the entire assembly. Example

[0035] In the field of sewage treatment sampling devices, we have further expanded the functions and application scope of the devices. Figures 1 to 4 As shown, the sampling device of this embodiment is similar in structure to that of the first embodiment, but with some innovative designs added.

[0036] First, we retained the core components such as the sampling tank 14, the connector 13, the valve 8, the liquid suction port 7, the assembly frame 4, the assembly head 5, the T-shaped mounting bar 2 and the stepper motor 11 to ensure that the basic functions of the device were retained.

[0037] At the same time, we added a docking seat 9 to the upper end of valve 8, and opened a hexagonal hole 10 at the upper end of docking seat 9, which perfectly matches the hexagonal column 12 at the output end of stepper motor 11. This design makes it easier to connect and disconnect stepper motor 11 from valve 8, thereby improving the flexibility and maintainability of the device.

[0038] In actual use, by driving the hexagonal column 12 to rotate in the hexagonal hole 10 by the stepper motor 11, we can easily control the opening and closing of the valve 8. In this way, the liquid suction port 7 can be used to take in and out liquid as needed, thereby achieving sewage sampling in the sampling tank 14.

[0039] Furthermore, we've optimized the device's scalability. By employing a combination of multiple assembly racks 4, assembly heads 5, and mounting components 3, we can simultaneously install and use multiple sampling tanks 14. This design not only improves sampling efficiency but also makes the device more suitable for large-scale sewage sampling.

[0040] At the same time, we installed a master control box 1 on the upper end of the multiple T-shaped mounting bars 2, and placed the integrated circuit board of the stepper motor 11 inside. In this way, we can centrally control the multiple stepper motors 11 through the master control box 1, realizing the simultaneous operation and management of multiple sampling tanks 14.

[0041] For easy carrying and installation, we also provide a hanging hole 15 on the outer wall of the master control box 1. Like this, the user just can hang the device in a suitable position conveniently, further improving the convenience and practicality of the device.

[0042] In general, the sampling device of this embodiment, while retaining its basic functions, has been improved by adding the design of the docking seat 9 and the hexagonal column 12 and optimizing the scalability and convenience, making the device more in line with actual usage needs and providing a more efficient and reliable sampling tool for sewage prevention and control work.

[0043] Sampling process: First, confirm that all parts of the sampling device have been correctly installed and are in good condition. Connect the sampling tank 14 tightly to the valve 8 through the connector 13 to ensure the sealing of the sampling tank 14.

[0044] The sampling device is fixed to the desired sampling location using the assembly frame 4 and assembly head 5. The assembly head 5 is securely connected to the T-shaped mounting bar 2 via the mounting member 3 to ensure the stability and reliability of the sampling device. Alternatively, a rope can be used for hanging the sampling device. With the rope secured to the hanging hole 15, the sampling tank 14 can be lowered below the sewage surface to sample sewage at varying depths.

[0045] Insert the hexagonal column 12 at the output end of the stepper motor 11 into the hexagonal hole 10 of the docking seat 9 at the upper end of the valve 8. Ensure that the hexagonal column 12 fits the hexagonal hole 10 so that the stepper motor 11 can drive the valve 8 to rotate.

[0046] Start the stepper motor 11, which drives the hexagonal column 12 to rotate, thereby driving the valve 8 to open and close. When the valve 8 is open, the sewage enters the sampling tank 14 through the suction port 7; when the valve 8 is closed, the sampling process ends.

[0047] After the sampling is completed, the valve 8 is closed and the sampling can 14 is removed. The sampling can 14 is properly stored and the sample is transported to the laboratory for analysis and processing as soon as possible.

[0048] After the sampling is completed, the sampling device is maintained and cleaned up as necessary. The liquid suction port 7 and the sampling tank 14 are cleaned up to ensure that there is no residue inside to prevent interference with the next sampling.

[0049] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0050] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
