Description

Technical Field

[0001] This utility model relates to the field of electrochemical sensor technology, and in particular to a fixing device for calibrating electrochemical sensors. Background Technology

[0002] An electrochemical sensor calibration fixture is a specially designed mechanical device intended to provide a stable and precise environment and position to ensure the consistency and accuracy of the electrochemical sensor during the calibration process. Electrochemical sensors are widely used in fields such as solution concentration measurement, gas detection, and pH monitoring. Their performance is often affected by temperature, pressure, concentration, and solution composition. Therefore, the role of the fixture is to provide physical support for the electrochemical sensor during the calibration process.

[0003] In the prior art, such as Chinese Patent No. CN202223369418.9, this utility model applies to the field of sensor fixing technology and provides a sensor fixing device, including an installation component, a rotating component, and a fixing component. The installation component includes a suction cup, and an air extraction cylinder and an air release valve are installed on the top of the suction cup. The rotating component includes an annular perforated plate fixedly installed on the top of the suction cup. A ball joint universal joint is installed in the annular hole of the annular perforated plate, and a connecting rod is provided on the top of the universal joint. The top of the connecting rod is fixedly connected to a connecting plate. The fixing component is rotatably connected to the top of the connecting plate. Therefore, after fixing the sensor to a wall or floor, the sensor can be rotated by the rotating component, so that the sensor can measure the length, width, and height of the room from a single base point. There is no predetermined direction, and the measurement direction can be adjusted at will, making it convenient to use.

[0004] While the above-mentioned solutions offer advantages, they typically involve two-point clamping to fix the sensor. Specifically, the clamping device holds both ends of the sensor to ensure its relative position during calibration. However, this two-point clamping method has limitations. Due to the limited number of clamping points, the sensor is prone to shaking or shifting under force or external disturbances. This is especially true for high-precision measurements or highly sensitive sensors, where even minor shaking or shifting can lead to significant measurement errors. Furthermore, the lack of additional support points to evenly distribute the clamping force means the sensor may not maintain sufficient stability during fixation, causing it to shift position easily when in contact with the standard solution, thus affecting the accuracy and repeatability of the measurement results. Utility Model Content

[0064] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0065] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0066] Example 1, such as Figures 1-7 As shown, this utility model provides a fixing device for calibrating an electrochemical sensor, including: a device body 1, a fixing component, and a calibration component;

[0067] The fixing component includes: a clamping member 101 is provided on the top of the device body 1, and a clamping cavity 102 is provided inside the clamping member 101. In this design, the clamping member 101 can clamp and fix the electrochemical sensor body 103. The electrochemical sensor body 103 is provided inside the clamping cavity 102. A first electric telescopic rod 104 is fixedly embedded in the front side of the inside of the clamping cavity 102. A connecting plate 105 is fixedly connected to the rear side of the first electric telescopic rod 104. The connecting plate 105 is slidably connected inside the clamping cavity 102.

[0068] It should be noted that the first electric telescopic rod 104 can serve as a power source, enabling the connecting plate 105 to slide back and forth inside the clamping cavity 102.

[0069] The clamping cavity 102 is provided with two first soft pads 106. In this design, the first soft pads 106 can prevent the clamping member 101 from making hard contact with the electrochemical sensor body 103, thus preventing damage to the electrochemical sensor body 103. One of the first soft pads 106 is fixedly connected to the rear side of the connecting plate 105, and the other first soft pad 106 is fixedly connected to the front side of the inner wall of the clamping cavity 102. Connecting posts 108 are slidably connected to both sides of the inside of the clamping cavity 102.

[0070] In addition, a second push block 109 is fixedly installed on the opposite side of each of the two connecting columns 108, and two first push blocks 107 are fixedly installed on the rear side of the connecting plate 105. The opposite side of each of the two first push blocks 107 is slidably connected to the opposite side of the second push block 109. A slider 110 is fixedly installed on the opposite side of each of the two first push blocks 107. A groove 111 is opened inside each of the two second push blocks 109. In this design, the slider 110 slides inside the groove 111. The movement range of the slider 110 can be limited by the groove 111 to prevent the slider 110 from shaking when sliding. Both sliders 110 are slidably connected to the inner surface of the groove 111.

[0071] It should be noted that the two first push blocks 107, the two second push blocks 109, and the two connecting columns 108 are all movably embedded inside the clamping member 101, so as to protect it through the clamping member 101 and prevent the structural movement from being affected by external factors.

[0072] Among them, a return spring 112 is fixedly installed on one side of each of the two second push blocks 109. In this design, the return spring 112 can provide a reset function for the second push block 109 so that it can be reset to the initial position when the external force disengages from the second push block 109. The other end of each of the two return springs 112 is fixedly connected to the outer surface of the clamping cavity 102. A clamping plate 113 is fixedly installed on one side of each of the two connecting columns 108. A second soft pad 114 is fixedly connected on one side of each of the two clamping plates 113. Both clamping plates 113 are movably embedded inside the clamping cavity 102.

[0073] It should be noted that both clamps 113 and the two second soft pads 114 are T-shaped, which means that when the two clamps 113 drive the second soft pads 114 to adhere to the left and right sides of the electrochemical sensor body 103, they can also adhere to its bottom.

[0074] In this embodiment, the operator can first pick up the electrochemical sensor body 103, and then push the electrochemical sensor body 103 upward so that it can be embedded into the inside of the clamping cavity 102, and so that the front side of the electrochemical sensor body 103 can fit against the first soft pad 106 on the rear side, so as to clamp and fix the electrochemical sensor body 103 by the clamping member 101.

[0075] Example 2, as Figures 1-7 As shown, the calibration assembly includes: a gantry 2 fixedly mounted on the top of the device body 1; a second electric telescopic rod 201 fixedly mounted on the top side inside the gantry 2; a support plate 202 fixedly mounted on the bottom of the second electric telescopic rod 201; and the support plate 202 slidably connected inside the gantry 2. In this design, the support plate 202 slides inside the gantry 2 to constrain the movement direction of the support plate 202 and avoid lateral swaying or offset, thereby ensuring the stability and accuracy of the clamping member 101 during vertical movement. The support plate 202 is fixedly connected to the top of the clamping member 101.

[0076] The device body 1 has a water storage tank 203 fixedly installed on the top. The water storage tank 203 is located inside the gantry frame 2. A rotating rod 204 is movably embedded inside the water storage tank 203. Multiple stirring blades 205 are fixedly installed on both outer surfaces of the rotating rod 204. A motor 206 is fixedly installed on the front side of the rotating rod 204. In this design, the motor 206 serves as a power source and can drive the stirring blades 205 to rotate in a circle inside the water storage tank 203 through the rotating rod 204. The motor 206 is rigidly connected to the front side of the water storage tank 203 through a support member. A water outlet pipe 207 is fixedly embedded on the bottom side inside the water storage tank 203. The outer surface of the water outlet pipe 207 is fixedly installed on the top side inside the device body 1. A one-way valve 208 is installed inside the water outlet pipe 207.

[0077] It should be noted that the water storage tank 203, as a container, is capable of storing standard solutions;

[0078] In addition, the motor 206 is fixed to the front side of the water storage tank 203 by the support, which can increase the stability of the motor 206 and prevent the motor 206 from shaking or vibrating during operation, thus affecting the operation of the motor 206.

[0079] In this embodiment, personnel can first pour a standard solution into the water storage tank 203, and then activate the second electric telescopic rod 201 through its power supply system. When the rod extends, it pushes the support plate 202 downward inside the gantry 2. As the support plate 202 moves, the electrochemical sensor body 103 is driven to descend synchronously through the clamping member 101, so as to embed the electrochemical sensor body 103 into the water storage tank 203. Afterwards, personnel can use the electrochemical sensor body 103 to detect the value of the standard solution in order to calibrate the electrochemical sensor body 103.

[0080] Working principle: In use, when the electrochemical sensor body 103 is embedded inside the clamping cavity 102, the operator can activate the first electric telescopic rod 104 via its power supply system. As it extends, the first soft pad 106 is pushed backward by the connecting plate 105, thus fitting the first soft pad 106 against the front and rear sides of the electrochemical sensor body 103. When the connecting plate 105 moves, it pushes the first pushing block 107 backward, which in turn pushes the slider 110 to slide on the inner surface of the groove 111. As the slider 110 slides, the first pushing block 107 presses against the second pushing block 109. When block 109 is compressed, the connecting column 108 can push the clamping plate 113 to move relative to each other inside the clamping cavity 102. The clamping plate 113 can also drive the second soft pad 114 to move synchronously, so that the second soft pad 114 fits against the left and right sides of the electrochemical sensor body 103 and clamps and fixes it. Through the structure of the connecting plate 105 and the clamping plate 113, the first soft pad 106 and the second soft pad 114 can be accurately fitted to the front, back, left and right sides of the electrochemical sensor body 103, ensuring that the electrochemical sensor body 103 is clamped evenly and stably, avoiding displacement or deformation of the electrochemical sensor body 103, and ensuring its stability during operation.

[0081] In use, the operator can start the motor 206 via its power supply system. During operation, the motor drives the rotating rod 204 through its output shaft, which in turn drives the stirring blade 205 to rotate in a circle inside the water storage tank 203. This stirs the standard solution inside the tank, preventing stratification. After the standard solution is used up, the operator can open the one-way valve 208, allowing the standard solution to flow out of the water storage tank 203 through the outlet pipe 207. The structure of the stirring blade 205 and the outlet pipe 207 effectively stirs the standard solution, preventing stratification and ensuring that the stratified standard solution does not affect the subsequent calibration of the electrochemical sensor body 103.

[0082] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
