Description

[0002] Temperature and salinity are very important items in environmental measurement elements such as the ocean and lakes. When observing the environment of the ocean, lakes, etc., a temperature and salinity sensor is one of the necessary equipment.

[0003] Temperature and salinity profile measurement equipment (such as a hydrological probe) is mainly used for the rapid measurement of temperature and salinity profiles in ocean expeditions. It quickly falls in water by its own weight, and the temperature and salinity sensor it carries measures the water area it passes through quickly. Since its descent speed is relatively fast, with an average speed of 4 m / s, in order to obtain accurate temperature and salinity data, the response time of the temperature and salinity sensor needs to be short, reaching within 100 ms.

[0004] In order to ensure the firmness and sealing of the temperature and salinity sensor, the temperature and salinity sensor is usually fixed on the measurement equipment by means of potting. If the response time of the temperature and salinity sensor cannot meet the requirements, it will cause the potting parts and even the entire measurement equipment (such as a hydrological probe) to be scrapped. Therefore, before assembling the measurement equipment, it is necessary to detect the temperature and salinity sensor to avoid the situation of secondary assembly when it is not known whether the temperature and salinity sensor meets the requirements, so as to improve efficiency, save energy and labor.

[0028] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0029] Embodiment 1

[0030] This embodiment provides a response time test device 100 for the temperature and salinity sensor, including a base 1 and a test mechanism and a driving mechanism arranged on the base 1. The test mechanism includes a test rod 2, a test block 3, and an elastic member 4. One end of the test rod 2 is connected to the test block 3, and the other end of the test rod 2 is slidably connected to the base 1 and can be connected to the temperature and salinity sensor to be tested. The elastic member 4 is arranged between the test block 3 and the base 1. A constant temperature water bath is arranged below the test rod 2. The test block 3 and the base 1 cooperate to compress the elastic member 4 so that the test rod 2 can drive the temperature and salinity sensor to be tested to extend into the constant temperature water bath and be immersed in water. Under the action of the elastic force when the elastic member 4 restores its deformation, the test rod 2 can drive the temperature and salinity sensor to be tested to separate from the constant temperature water bath; the driving mechanism includes a driver 5 and a transmission component. The driver 5 is fixed on the base 1, and the driver 5 applies a force to the test block 3 by using the transmission component.

[0031] The response time test device 100 for the temperature-salinity sensor of the present utility model, when in use, the temperature-salinity sensor to be tested can be communicatively connected to the test software. When conducting a test, the temperature-salinity sensor to be tested is connected to the test rod 2. The driver 5 applies a force to the test block 3 by means of a transmission assembly. The test block 3 compresses the elastic member 4 and drives the test rod 2 to extend into the constant temperature water bath, so that the temperature-salinity sensor to be tested is completely immersed in the water of the constant temperature water bath. After the driving mechanism removes the force applied to the test block 3, under the action of the elastic member 4 restoring its deformation, the test block 3 resets, driving the test rod 2 and the temperature-salinity sensor to be tested to disengage from the constant temperature water bath. Check the response time of the temperature-salinity sensor in the test software to determine whether the response time of the temperature-salinity sensor meets the index requirements. The response time test device 100 for the temperature-salinity sensor of the present utility model uses the cooperation of the test mechanism and the driving structure to drive the temperature-salinity sensor to be tested to move up and down reciprocally, with stable movement, which provides a strong guarantee for the response time test of the temperature-salinity sensor, conducts the response time test on the temperature-salinity sensor to be assembled, and effectively improves the working reliability of the temperature-salinity profile measurement equipment.

[0032] Among them, the transmission assembly includes a transmission shaft 6 and an eccentric wheel 7. The output end of the driver 5 is connected to the transmission shaft 6 to drive the transmission shaft 6 to rotate. The transmission shaft 6 is connected to the eccentric wheel 7 to drive the eccentric wheel 7 to rotate. The axis of the transmission shaft 6 does not coincide with the axis of the eccentric wheel 7. The outer peripheral surface of the eccentric wheel 7 abuts against the test block 3 to apply a force to the test block 3. The driver 5 drives the eccentric wheel 7 to rotate by means of the transmission shaft 6. The eccentric wheel 7 rotates eccentrically, thereby realizing intermittent force application to the test block 3. When the axis of the eccentric wheel 7 is located below the axis of the transmission shaft 6, the eccentric wheel 7 presses down the test block 3. The test block 3 drives the temperature-salinity sensor to be tested to move downward into the constant temperature water bath through the test rod 2, and the water in the constant temperature water bath submerges the temperature-salinity sensor to be tested. When the axis of the eccentric wheel 7 is located above the axis of the transmission shaft 6, the temperature-salinity sensor to be tested completely disengages from the constant temperature water bath. By adjusting the rotation speed of the driver 5, the requirements for the response time test of the temperature-salinity sensor can be met. It should be explained here that reasonably setting the specifications of the eccentric wheel 7 and the test rod 2 to cooperate with the water in the constant temperature water bath to realize the response time test of the temperature-salinity sensor to be tested is a common means in this field and will not be elaborated here.

[0033] In this specific embodiment, the driver 5 can be selected as a motor, and a speed regulator is used to adjust the rotation speed of the driver 5. The motor can be selected as a servo motor or a stepper motor with higher precision to further improve the test accuracy of the device. The output end of the driver 5 is connected to the transmission shaft 6 by means of a coupling 8 to ensure the smooth transmission of power.

[0034] In other specific embodiments achievable by the present utility model, the test block 3 has a plate-like structure, and wear-resistant structural layers are provided on the outer peripheries of both the test block 3 and the eccentric wheel 7 to improve the structural strength of the test block 3 and the eccentric wheel 7, extend the service life of the device, enhance the wear resistance of the test block 3 and the eccentric wheel 7, and also ensure the accuracy of the test structure of the device.

[0035] In this specific embodiment, the elastic member 4 is a spring, and the elastic member 4 is sleeved on the test rod 2, which is convenient for installation. The test rod 2 plays a role in limiting the elastic member 4 and ensures the stability of the elastic member 4.

[0036] More specifically, a sensor mounting seat 9 is connected to the end of the test rod 2 away from the test block 3, and the temperature and salinity sensor to be measured is detachably connected to the sensor mounting seat 9. The sensor mounting seat 9 is provided to stably support the temperature and salinity sensor to be measured, ensure the stability of the temperature and salinity sensor during the test process, and ensure the smooth progress of the test.

[0037] In this specific embodiment, the base 1 includes a vertical bracket 10, a horizontal bracket 11, and a bottom plate 12. The vertical bracket 10 has an inverted U-shaped structure, which ensures the structural stability of the base 1. The driver 5 is installed on the vertical bracket 10 using fasteners. The number of the bottom plates 12 is two groups, and the bottom plates 12 are connected to both side columns of the vertical bracket 10. The bottom plates 12 are provided to increase the bottom area of the base 1 and further improve the stability of the base 1. The horizontal bracket 11 is arranged perpendicular to the vertical bracket 10, and the test block 3 is located above the horizontal bracket 11. The test rod 2 slidably passes through the horizontal bracket 11 and is connected to the temperature and salinity sensor to be measured. The test rod 2 is located between the two side columns of the vertical bracket 10. The horizontal bracket 11 is provided to provide stable support for the test mechanism, and at the same time, to prevent the vertical bracket 10 from affecting the movement of the test mechanism. The constant temperature water bath is arranged below the test mechanism and does not interfere with the base 1, making reasonable use of space, reducing the space occupied by the device, and being beneficial to improving the flexible adaptability of the device. In practical applications, the base 1 can be manufactured by welding to enhance the structural integrity, ensure the structural strength, and provide stable support for the test mechanism and the drive mechanism.

[0038] In addition, the test mechanism further includes a guide rod 13, which is arranged parallel to the test rod 2. One end of the guide rod 13 is connected to the test block 3, and the other end of the guide rod 13 is slidably connected to the base 1. The guide rod 13 arranged parallel to the test rod 2 provides a limiting and guiding effect for the reciprocating movement of the test rod 2, prevents the test rod 2 from deflecting and misaligning during the reciprocating movement, ensures the accuracy of the reciprocating movement of the test rod 2 driving the temperature and salinity sensor to be measured, and thus improves the test accuracy of the device.

[0039] In practical applications, linear bearings 14 can be provided between both the test rod 2 and the guide rod 13 and the base 1 to further improve the reciprocating movement accuracy of the test rod 2 and the guide rod 13.

[0040] Embodiment 2

[0041] This embodiment provides a test device 100 for the response time of a temperature-salinity sensor. Among them, the test rod 2 has a prismatic structure, which can adopt a triangular prism, a quadrangular prism or a multi-prism structure. The base 1 is provided with a sliding hole adapted to the test rod 2 to ensure the accuracy of the reciprocating motion of the test rod 2 and avoid deflection during the reciprocating motion of the test rod 2, which affects the temperature-salinity sensor to be tested from entering the constant temperature water tank, thereby improving the working reliability of the device.

[0042] The other structures of the test device 100 for the response time of the temperature-salinity sensor in this embodiment are the same as those in Embodiment 1 and will not be elaborated here.

[0043] When the test device 100 for the response time of the temperature-salinity sensor of the present utility model is in use, the temperature-salinity sensor to be tested is fixed on the sensor mounting seat 9. The base 1 is fixed at the upper end of the constant temperature water tank. Power is supplied to the driver 5, and the speed of the driver 5 is adjusted through the speed regulator to drive the eccentric wheel 7 to rotate. Under the action of the compression elastic force of the elastic member 4, the upper end surface of the test block 3 is always tangent to the outer circle of the eccentric wheel 7. The test block 3 moves up and down under the action of the eccentric wheel 7 and the elastic member 4, thereby driving the temperature-salinity sensor to be tested to move up and down. When the temperature-salinity sensor to be tested is at the lowest end, it is completely immersed in the water of the constant temperature water tank, and when it is at the highest end, it is completely separated from the constant temperature water tank. After the speed is stable, check the response time test software of the temperature-salinity sensor to determine whether the response time of the temperature-salinity sensor meets the index requirements. The test device 100 for the response time of the temperature-salinity sensor of the present utility model has a reasonable structural design and a stable working process. It should be explained here that the response time test software of the temperature-salinity sensor is a common means for those skilled in the art and will not be elaborated here.

[0044] In the present utility model, specific examples are used to elaborate the principle and implementation mode of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
