Technical Field
[0001] This utility model relates to the field of water quality testing technology, and in particular to a portable anti-interference device for on-site water quality testing. Background Technology
[0002] On-site water quality testing refers to the rapid and convenient testing and analysis of water bodies at the sampling location to obtain key water quality parameters and pollutant information. This eliminates the need to transport water samples back to a laboratory for complex processing. This testing method is characterized by its portability, speed, and real-time response to on-site water quality conditions, and is commonly used in environmental monitoring, drinking water safety inspections, and industrial wastewater discharge supervision. Anti-interference devices are used to suppress, shield, or eliminate external electromagnetic, signal, and physical interference to ensure stable and accurate operation of equipment in complex and harsh environments. Their core function is to enhance the system's anti-interference capability and ensure signal quality and system reliability.
[0003] A search revealed Chinese Patent Publication No. CN203204436U, which discloses a real-time water resource monitoring and control terminal device. The device includes an inner shell containing a control board. The control board houses modules for temperature detection, flow rate detection, water level detection, hydrology detection, water quality monitoring, pump control, valve control, communication, PLC detection and control, temperature and humidity control, and display control. Each module is connected to the PLC detection and control module. The inner shell has sockets and control buttons. This invention employs a PLC control system, which exhibits excellent anti-interference capabilities, high reliability, and a long mean time between failures (MTBF). The PLC detection and control module has a built-in hardware fault self-detection function, promptly issuing alarm information in case of a fault. This invention can connect to various field devices and can be used in industrial control applications of various scales. However, in practical use, the above-mentioned devices are not convenient to carry at all times, which limits the application scenarios, increases maintenance costs and manpower burden, and technicians may also delay the handling time in emergency situations due to the inconvenience of carrying them, ultimately affecting the flexibility and reliability of the overall anti-interference system. To address these issues, a portable anti-interference device for on-site water quality testing is proposed. Utility Model Content
[0004] This utility model proposes a portable anti-interference device for on-site water quality testing, aiming to improve the problem that some existing devices cannot be conveniently carried.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A portable anti-interference device for on-site water quality testing includes a top support frame and a bottom support frame, with a central connecting module provided between the top support frame and the bottom support frame;
[0007] The middle connecting module includes four fixed shafts. The four fixed shafts are rotatably connected to the interior of the top support frame and the bottom support frame on their adjacent sides. An outer rotating plate is fixedly connected to the outside of one of the fixed shafts, and an inner rotating plate is fixedly connected to the outside of another outer rotating plate. A connecting shaft is rotatably connected to the interior of the outer rotating plate and the inner rotating plate.
[0008] The above solution enables a portable anti-interference device for on-site water quality testing to achieve overall stability and portability through a structural design consisting of a top support frame, a bottom support frame, and a central connecting module. The central connecting module comprises four fixed shafts, which are rotatably connected to the upper and lower support frames, giving the device good mechanical linkage. An outer rotating plate is installed outside one of the fixed shafts, and an inner rotating plate is fixedly connected to another outer rotating plate. The linkage structure between the rotating plate and the connecting shaft improves the device's anti-interference capability in different environments and facilitates the rapid deployment and retraction of the testing equipment, thereby improving the efficiency and accuracy of the testing work.
[0009] As a further description of the above technical solution:
[0010] Both the top support frame and the bottom support frame have strip-shaped holes on one side of their bottom. One end of the outer rotating plate and the inner rotating plate is fixedly connected to a sliding shaft, and the sliding shaft is slidably connected to the outside of the strip-shaped hole.
[0011] The above solution involves setting strip-shaped holes at the bottom of the top and bottom support frames, fixing sliding shafts on the outer and inner rotating plates, and slidably connecting the sliding shafts with the strip-shaped holes. This achieves the guiding and limiting function of the structure during the unfolding and retraction process, improves the stability and anti-interference ability of the device during movement, and ensures coordinated movement between components, thereby enhancing the practicality and adaptability of the whole machine.
[0012] As a further description of the above technical solution:
[0013] Side sliding frames are fixedly connected to adjacent sides of both the top support frame and the bottom support frame. Side transparent glass is slidably connected inside the two side sliding frames, and hidden handles are fixedly connected to the outside of the side transparent glass.
[0014] The above solution involves setting a side sliding frame on the adjacent side of the top and bottom support frames, and sliding a transparent glass panel inside the frame. A hidden handle is then installed on the outside of the glass panel, which effectively closes and opens the side space of the device. This not only enhances the device's protective performance and safety but also allows on-site testing personnel to operate the device flexibly as needed, improving its ease of use and visual observation. This further enhances the overall structure's practical value and adaptability to the field.
[0015] As a further description of the above technical solution:
[0016] Both the top support frame and the bottom support frame are fixedly connected to a front sliding frame on their adjacent sides. The two front sliding frames are slidably connected to a front transparent glass, and both front transparent glass are fixedly connected to a hidden handle on their exterior.
[0017] The above solution involves setting a front sliding frame on a similar side of the top and bottom support frames, sliding a front transparent glass inside the frame, and then setting a hidden handle on the outside of the glass. This allows for effective sealing and opening of the front space of the device, enhancing its sealing performance and anti-contamination capabilities. It also facilitates quick observation and operation by testing personnel, improving the device's on-site operability and environmental adaptability, thereby further optimizing the overall structure's practicality and portability.
[0018] As a further description of the above technical solution:
[0019] The top support frame is slidably connected to a top transparent glass panel, and the bottom support frame is slidably connected to a bottom transparent glass panel. Both the top and bottom transparent glass panels are fixedly connected to a hidden handle on their exteriors.
[0020] The above solution involves sliding the top and bottom transparent glass together inside the top and bottom support frames, and fixing a hidden handle to the outside of the glass. This allows for the controllable opening and closing of the upper and lower spaces of the device, improving the overall sealing and protection capabilities of the structure. It also facilitates the rapid deployment and storage of the testing equipment in different environments, enhancing the flexibility of on-site operation and the ease of use of the equipment, and further improving the stability and practicality of the entire machine.
[0021] As a further description of the above technical solution:
[0022] Rubber support feet are fixedly connected to the four bottom corners of the bottom support frame.
[0023] The above solution, by setting rubber support feet at the four bottom corners of the bottom support frame, can effectively enhance the anti-slip performance and support stability of the device under different ground conditions, reduce interference caused by vibration or uneven terrain on the test results, and at the same time improve the overall structural durability and applicability, ensuring the continuity and reliability of on-site testing work.
[0024] As a further description of the above technical solution:
[0025] Both the top support frame and the bottom support frame have square holes in their middle areas, allowing the internal structure of the device to be observed after the top and bottom transparent glass are inserted.
[0026] The above solution involves creating square holes in the middle of the top and bottom support frames to allow direct observation of the internal structure of the device after the top and bottom transparent glass is inserted. This not only enhances the visibility during the testing process, making it easier for operators to monitor the equipment's operating status in real time, but also improves the accuracy and reliability of the device in complex environments, further optimizing the overall structure's practicality and user experience.
[0027] This utility model has the following beneficial effects:
[0028] 1. In this utility model, a foldable rigid frame is used to connect and fix multiple transparent observation plates and the operating side, making the anti-interference device easy to carry.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a portable anti-interference device for on-site water quality testing, comprising a top support frame 1 and a bottom support frame 2. Both the top support frame 1 and the bottom support frame 2 are rectangular frame structures with good corrosion resistance and wear resistance. The edges and corners of the frames are rounded to prevent scratching the operator during use. They are located at the top and bottom ends of the device, respectively, to support the structure of the entire device and provide a mounting base for other components. A middle connecting module 3 is provided between the top support frame 1 and the bottom support frame 2. The middle connecting module 3 includes four fixed shafts 301. The fixed shafts 301 are cylindrical in shape and have high strength and good corrosion resistance. The adjacent sides of the four fixed shafts 301 are rotatably connected to the inside of the top support frame 1 and the bottom support frame 2, respectively, so that the device can be flexibly folded and unfolded.
[0037] Specifically, the rectangular corrosion-resistant structure of the top and bottom support frames, combined with rounded corners, significantly improves the device's durability and operational safety, preventing injuries to personnel. The central connecting module uses four high-strength cylindrical fixed shafts to flexibly link the upper and lower frames via a rotating connection, enabling the device to fold and unfold freely. This greatly optimizes portability and spatial adaptability, facilitating on-site transport and rapid deployment. The overall frame structure is stable, with excellent corrosion resistance, adaptable to complex water quality environments. Simultaneously, the rigid connecting module reduces external vibration interference, ensuring the accuracy of test data. Balancing functionality and ergonomics, it reduces volume in a compact folded state and provides a stable support platform when unfolded, effectively solving the problems of bulkiness and insufficient anti-interference capabilities of traditional equipment, providing efficient and reliable hardware support for on-site water quality testing.
[0038] One of the fixed shafts 301 is externally fixedly connected to an outer rotating plate 302. The outer rotating plate 302 is rectangular in shape to facilitate rotation. The other outer rotating plate 302 is externally fixedly connected to an inner rotating plate 304. The inner rotating plate 304 is also rectangular in shape and made of the same material as the outer rotating plate 302. The outer rotating plate 302 and the inner rotating plate 304 are internally rotatably connected by a connecting shaft 303. The connecting shaft 303 is cylindrical in shape to ensure the stability and flexibility of rotation. Both the top support frame 1 and the bottom support frame 2 have strip-shaped holes 306 on one side of their bottom to guide the movement of the sliding shaft 305. A sliding shaft 305 is fixedly connected to one end of both the outer rotating plate 302 and the inner rotating plate 304. The sliding shaft 305 is cylindrical in shape and made of aluminum alloy. It is externally slidably connected to the strip-shaped hole 306. The folding and unfolding operation of the device is realized by sliding the sliding shaft 305 in the strip-shaped hole 306.
[0039] Specifically, the rectangular design and identical material configuration of the outer rotating plate 302 and the inner rotating plate 304, combined with the cylindrical connecting shaft 303, achieve stable and flexible bidirectional rotation. The cylindrical sliding shaft 305, made of aluminum alloy, precisely engages with the strip-shaped holes 306 in the top and bottom support frames, forming a low-friction guiding mechanism during sliding. This ensures smooth and stable folding and unfolding of the device. Simultaneously, the design of the rectangular rotating plate and the cylindrical sliding shaft balances spatial adaptability and mechanical load-bearing capacity, effectively reducing the risk of wear during repeated operations. The linear constraint of the strip-shaped holes 306 further enhances the accuracy of the sliding shaft 305's movement trajectory, preventing deviation and jamming, thus maintaining the device's anti-interference capability in complex environments. The overall structure, through the synergistic effect of rigid rotation and sliding components, optimizes portability and enhances the device's morphological stability in both folded and unfolded states, providing efficient and reliable hardware support for water quality testing.
[0040] Reference Figure 3 and Figure 4 Side sliding frames 4 are fixedly connected to adjacent sides of the top support frame 1 and the bottom support frame 2. The side sliding frames 4 are rectangular frame structures with good sliding performance. Side transparent glass 5 is slidably connected inside the two side sliding frames 4. The side transparent glass 5 is rectangular in shape and made of high-strength tempered glass with good light transmission and impact resistance. Hidden handles are fixedly connected to the outside of the side transparent glass 5. These handles are arc-shaped and have an anti-slip surface, making it easy for operators to quickly open or close the side transparent glass 5 when needed. Front sliding frames 6 are fixedly connected to adjacent sides of the top support frame 1 and the bottom support frame 2. The front sliding frames 6 are rectangular frame structures and made of the same material as the side sliding frames 4. Front transparent glass 7 is slidably connected inside the two front sliding frames 6. The front transparent glass 7 is rectangular in shape and made of high-strength tempered glass, the same material as the side transparent glass 5. Hidden handles are fixedly connected to the outside of the front transparent glass 7.
[0041] Specifically, the rectangular side sliding frame 4 and the front sliding frame 6, located on the same side of the top and bottom support frames, combined with the high-strength tempered glass side transparent glass 5 and the front transparent glass 7 with internal sliding connections, ensure light transmission, impact resistance, and environmental adaptability. The low-friction sliding characteristics of the sliding frame and glass components enable rapid opening and closing operations. The concealed curved handle, treated with anti-slip material, conforms to ergonomics, balancing concealment and ease of operation, reducing the risk of accidental contact and improving response efficiency in emergencies. The rigid combination of the rectangular frame and tempered glass maintains structural stability during sliding, effectively isolating external vibrations and water quality interference. The high light transmission design of the transparent glass facilitates on-site observation of the testing process. The precise fit between the sliding frame and the glass ensures efficient space utilization when the device is folded and unfolded, while also enhancing overall sealing and protection performance, providing a clear, visible, and interference-resistant working environment for water quality testing.
[0042] The top support frame 1 has a sliding connection to a top transparent glass 8, which is rectangular in shape and made of high-strength tempered glass, providing good light transmission and impact resistance. The bottom support frame 2 has a sliding connection to a bottom transparent glass 10, which is the same shape and material as the top transparent glass 8. Both the top transparent glass 8 and the bottom transparent glass 10 have hidden handles fixedly connected to their exteriors. The bottom four corners of the bottom support frame 2 are fixedly connected to rubber support feet 9, which are cylindrical in shape and made of wear-resistant rubber, providing good anti-slip and shock absorption performance, ensuring the stability of the device under different ground conditions. The middle areas of both the top support frame 1 and the bottom support frame 2 have square holes, which allow the top transparent glass 8 and the bottom transparent glass 10 to be inserted so that the internal condition of the device can be clearly observed, facilitating water quality testing operations.
[0043] Specifically, the top transparent glass 8 and bottom transparent glass 10, made of high-strength tempered glass, are slidably connected within the top and bottom support frames. Their rectangular structure and light-transmitting, impact-resistant properties allow for easy opening and closing via an external hidden handle. The square opening in the center of the frame enables comprehensive visualization of the device's internal state, ensuring a clear and controllable water quality testing process. The cylindrical, wear-resistant rubber support feet 9 at the four bottom corners effectively adapt to different ground conditions, reducing environmental vibration interference and improving device stability. The symmetrical sliding structure of the top and bottom transparent glass ensures both the sealing of the testing environment and operational flexibility. The high strength of the tempered glass and the cushioning effect of the rubber support feet synergistically enhance the overall impact resistance of the device. The combination of the square opening and transparent components optimizes the accessibility and monitoring accuracy of the testing space, providing reliable support for water quality testing in complex environments.
[0044] Working principle: The operator first places the rubber support feet 9 at the bottom of the bottom support frame 2 stably on the testing table. Then, by pushing the outer rotating plate 302 and the inner rotating plate 304, the connecting shaft 303 and the sliding shaft 305 are moved synchronously within the strip-shaped hole 306, causing the top support frame 1 and the bottom support frame 2 to unfold to a horizontal state along the fixed shaft 301. After unfolding, the operator holds the hidden handles on the outside of the side transparent glass 5 and the front transparent glass 7, and slides the glass panels outward along the tracks of the side sliding frame 4 and the front sliding frame 6, revealing the internal space of the device. At this time, the water quality test tube is inserted through the square hole of the top support frame 1. The testing instrument is placed on the surface of the bottom transparent glass 10. Then, the side transparent glass 5, the front transparent glass 7, and the top transparent glass 8 are slid in the opposite direction to close all the transparent panels and form a sealed testing chamber. During the testing process, the operator can observe the data on the display screen of the testing instrument in real time through the top transparent glass 8, the bottom transparent glass 10, and the side transparent glass 5. After the test is completed, the transparent glass panels are slid again to remove the equipment, and the outer rotating plate 302 and the inner rotating plate 304 are operated in the opposite direction to make the sliding shaft 305 retract along the strip hole 306, which drives the top support frame 1 and the bottom support frame 2 to fold around the fixed shaft 301, and finally store it in a compact form.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
