Description

Technical Field

[0001] This utility model relates to the field of digital ion sensor technology, and more specifically, to a digital ion sensor with a small, double-layer structure for control. Background Technology

[0002] Digital ion sensors are used to detect the concentration of specific ions in liquids. They have the advantages of high precision and easy integration, and are widely used in water quality monitoring, medical diagnosis and agricultural irrigation. By applying digital ion sensors to groundwater wells, real-time monitoring of groundwater ion concentration can be achieved, providing data support for water resource management and environmental protection.

[0003] Since most digital ion sensors on the market have a diameter greater than 20 millimeters, they cannot be used in groundwater wells with a diameter of less than 20 millimeters. Furthermore, when used in wells with a diameter of less than 20 millimeters, digital ion sensors are not securely fixed and are prone to shaking due to friction with the well wall in the water, affecting measurement accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a digital ion sensor with a small, double-layer structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a digital ion sensor with a small, double-layer structure, including an electrode upper shell. An electrode body is threadedly connected to the bottom of the electrode upper shell, and an electrode top cover is threadedly connected to the top of the electrode upper shell. An auxiliary fixing mechanism is provided on the outer wall of the top of the electrode upper shell. The auxiliary fixing mechanism includes a fixing ring sleeved on the outer wall of the top of the electrode upper shell. Several rectangular grooves are evenly distributed on the side wall of the fixing ring. Support members are slidably connected to the inner walls of the rectangular grooves. A buffer spring is fixedly connected between the support member and the side wall of the rectangular groove. A rubber block is fixedly connected to the side wall of the support member away from the buffer spring. The number of buffer springs and rubber blocks is the same as the number of support members.

[0006] As a further improvement to this technical solution, the rubber block has an arc-shaped profile at the end away from the support member, and horizontal grooves are uniformly provided at the end of the rubber block away from the support member.

[0007] As a further improvement to this technical solution, the outer wall of the arc-shaped side of the rubber block is initially set to extend out of the rectangular groove opening area, and the rubber block will first contact the mounting surface when installed with the fixing ring.

[0008] As a further improvement to this technical solution, a single reference electrode is inserted inside the electrode body, and a circuit board is fixedly connected to the outer wall of the top of the single reference electrode. A solution grounding temperature probe is also inserted inside the electrode body and on one side of the single reference electrode. An electrolyte filling cavity is opened at the top of the electrode body, and a filling liquid head is inserted at the top of the electrolyte filling cavity. The single reference electrode, circuit board, solution grounding temperature probe, filling liquid head, and electrolyte filling cavity are all located inside the electrode upper shell after the electrode upper shell is combined with the electrode body.

[0009] As a further improvement to this technical solution, an electrode sheath is threadedly connected to the bottom of the electrode body, and an electrode membrane head is installed inside the electrode sheath.

[0010] As a further improvement to this technical solution, a rubber ring is fixedly connected to the inner wall of the fixing ring, and the rubber ring is located between the inner wall of the fixing ring and the outer wall of the electrode upper shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this small, dual-layer digital ion sensor, an auxiliary fixing mechanism is used. When the electrode shell descends to a suitable height on the inner wall of the well, the rebound characteristic of the buffer spring causes the support component to return to its original position with the rubber block. The arc-shaped surface of the rubber block is firmly in contact with the inner wall of the well. Multiple transverse grooves increase the friction between the rubber block and the inner wall of the well, ensuring that the fixing ring does not shift up or down, thus improving the stability of the device and enhancing measurement accuracy.

[0021] Example 1

[0022] Please see Figures 1-4 As shown, this embodiment provides a digital ion sensor with a small, double-layer structure, including an electrode upper shell 1. An electrode body 2 is threadedly connected to the bottom of the electrode upper shell 1, and an electrode top cover 3 is threadedly connected to the top of the electrode upper shell 1. An auxiliary fixing mechanism 4 is provided on the outer wall of the top of the electrode upper shell 1. The auxiliary fixing mechanism 4 includes a fixing ring 41 sleeved on the outer wall of the top of the electrode upper shell 1. Several rectangular grooves 42 are evenly distributed on the side wall of the fixing ring 41. Support members 43 are slidably connected to the inner walls of the rectangular grooves 42. Buffer springs 44 are fixedly connected between the support members 43 and the side walls of the rectangular grooves 42. A rubber block 45 is fixedly connected to the side wall of the support member 43 away from the buffer spring 44. The number of buffer springs 44 and rubber blocks 45 is the same as the number of support members 43. The rubber block 45 has an arc-shaped outline at the end away from the support member 43. Horizontal grooves are evenly opened at the end of the rubber block 45 away from the support member 43. The arc-shaped outer wall of the rubber block 45 is initially set to extend out of the opening area of ​​the rectangular groove 42. When the rubber block 45 is installed along with the fixing ring 41, it will first contact the mounting surface. A rubber ring 7 is fixedly connected to the inner wall of the fixing ring 41. The rubber ring 7 is located between the inner wall of the fixing ring 41 and the outer wall of the electrode upper shell 1.

[0023] By integrating different types of sensors into a miniaturized device, the device can be used in scenarios with small-diameter groundwater wells. A fixing ring 41 is fitted onto the outer wall of the top of the electrode housing 1. The friction between the rubber ring 7 and the outer wall of the electrode housing 1 increases resistance, firmly fixing the fixing ring 41 to the outer wall of the electrode housing 1. Then, the fixing ring 41, along with the electrode housing 1, is vertically inserted into the groundwater well with a diameter of less than 20 millimeters. This allows multiple rubber blocks 45 to initially contact the inner wall of the well. By simultaneously compressing the multiple rubber blocks 45, the rubber blocks... 45 pushes the support 43 to slide towards the buffer spring 44 inside the rectangular groove 42, and simultaneously squeezes the buffer spring 44. When the electrode upper shell 1 descends to the appropriate height on the inner wall of the water well, the rebound characteristics of the buffer spring 44 cause the support 43 to return to its original position with the rubber block 45, and make the arc surface of the rubber block 45 firmly contact the inner wall of the water well. With the help of multiple transverse grooves, the friction between the rubber block 45 and the inner wall of the water well is increased, ensuring that the fixing ring 41 will not move up and down, improving the stability of the equipment in the water well, and helping to improve the measurement accuracy.

[0024] A single reference electrode 51 is inserted inside the electrode body 2. A circuit board 52 is fixedly connected to the outer wall of the top of the single reference electrode 51. A solution grounding temperature probe 53 is also inserted inside the electrode body 2 and located on one side of the single reference electrode 51. An electrolyte filling cavity 55 is opened at the top of the electrode body 2, and a filling liquid end cap 54 is inserted at the top of the electrolyte filling cavity 55. The single reference electrode 51, circuit board 52, solution grounding temperature probe 53, filling liquid end cap 54, and electrolyte filling cavity 55 are all located inside the electrode upper shell 1 after the electrode upper shell 1 is combined with the electrode body 2. An electrode sheath 62 is also threaded to the bottom of the electrode body 2. The electrode housing 62 houses the electrode membrane head 61 and a circuit board 52, which is miniaturized and highly integrated. It includes functions such as signal acquisition, amplification circuit, signal processing, data storage, central processing unit, power isolation, fault diagnosis, A / D circuit conversion, and digital signal output. By integrating the single reference electrode 51, circuit board 52, solution grounding temperature probe 53, filling liquid seal head 54, and electrolyte filling cavity 55 into the electrode housing 1, and taking advantage of the fact that the diameter of the electrode housing 1 is less than or equal to sixteen millimeters, the device can be used in more groundwater wells with a diameter of less than twenty millimeters, thus expanding its application range.
