Description

[0041] Among them, a temperature detection rod 71 is fixedly connected to the bottom of the temperature detection part 7, and a thermistor is arranged inside the temperature detection rod 71, one end of which has an anti-corrosion effect. The temperature detection rod 71 passes through the annular stress sheet 52, and the outer wall of the shell 1 is provided with teeth. The cleaning mechanism 2 includes an annular screw block 21 meshing with the teeth, and the lower end surface of the annular screw block 21 is surrounded and fixedly connected with four groups of L-shaped frames 22, and the shorter end of the L-shaped frame 22 is fixedly connected with a round block 23, and one side of the round block 23 is surrounded and fixedly connected with three groups of cleaning blocks 233, and one end of the three groups of cleaning blocks 233 are all fitted with one end of the temperature detection rod 71. The line connection and control between the electrical connector 3, the control circuit board 4, the pressure detection part 5, the temperature detection part 7, the temperature detection rod 71 and the annular stress sheet 52 are all prior art, and for this reason, they are not further explained.

[0042] The present invention provides a temperature and pressure integrated sensor structure, in which teeth are provided on the surface of the shell, an annular screw block is threadedly connected to the teeth, an L-shaped frame is connected to the lower end of the annular screw block, one end of the L-shaped frame is connected to a round block, a cleaning block is provided on one side of the round block, and the cleaning block is arranged around the detection end of the temperature detection rod. By rotating the annular screw block, the cleaning block can be driven to rotate along the surface of the detection end of the temperature detection rod, and impurities attached to the detection end of the temperature detection rod can be scraped, thereby avoiding the influence of impurities on temperature detection, effectively improving the accuracy and working efficiency of temperature detection, and having practicality.

[0043] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0044] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0045] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0046] Example 1, please refer to Figure 2 , Figure 5 and Figure 6 , a temperature and pressure integrated sensor structure, a screw 31 is threadedly connected between the electrical connector 3 and the control circuit board 4 to improve the reliability of the connection, an electrical pin 6 is connected between the control circuit board 4 and the pressure detection element 5, and the pressure detection element 5 and the temperature detection element 7 are connected through the electrical pin 6, and the electrical pin 6 is used to transmit electrical signals and has a connection function;

[0047] Further, such as Figure 2 As shown, the bottom of the temperature detection member 7 is threadedly connected with an insulating tube 72, and the temperature detection rod 71 passes through the insulating tube 72. A sealing ring 73 is provided at one end of the insulating tube 72 to prevent water from entering the internal components from the gap between the temperature detection rod 71 and the insulating tube 72 when detecting the water temperature, thereby damaging the electrical components inside the sensor. The use of the sealing ring 73 should be checked regularly and replaced. The insulating tube 72 can prevent the insulating tube 72 from short-circuiting with the annular stress sheet 52 when passing through it, and can limit the temperature detection rod 71 at the same time;

[0048] Further, such as Figure 2 and Figure 3As shown, an electrical connector slot 11 is provided at the upper end of the shell 1, which is used to provide a movable space for the electrical connector 3 when the mutual inductor is disassembled or the pressure detection mode is adjusted, and the electrical connector 3 remains sealed when it moves up and down or is stationary in the electrical connector slot 11 to prevent the detection liquid from flowing into the shell and damaging the internal electrical components. A dynamic ring can be provided on the outer wall of the electrical connector 3, and a static ring can be provided on the inner wall of the electrical connector slot 11. The sealing effect is achieved by the cooperation of the dynamic ring and the static ring. The lower end of the shell 1 is designed to be open and communicated with the outside to facilitate temperature detection, so that the temperature detection rod 71 can directly contact the medium to be detected.

[0049] Embodiment 2 further optimizes the structure of a temperature and pressure integrated sensor provided in Embodiment 1. Specifically, Figure 3 As shown, a T-shaped groove 12 and a rectangular groove 13 are formed around the lower end of the housing 1. The rectangular groove 13 is connected to the T-shaped groove 12 and is used to adjust the pressure detection mode so that the detection medium acts on the annular stress sheet 52 through the rectangular groove 13 and detects the pressure value.

[0050] Further, such as Figure 2 As shown, a circular groove 231 is provided at the center of the circular block 23, and the circular groove 231 is located directly below the temperature detection rod 71. Impurities scraped off directly fall from the circular groove 231, and it is convenient for the detection medium to directly contact the temperature detection rod 71 from the circular groove 231. A circular sliding groove 232 is provided on one side of the circular block 23 for sliding connection with the baffle block 24, so that when the circular block 23 rotates downward, the baffle block 24 does not rotate with it, but only keeps moving downward with it.

[0051] Further, such as Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, an F-shaped block 25 is provided in the vertical end of the T-shaped groove 12, which is used to provide support for the pressure transmission block 54 and cooperate with the disassembly of the components inside the shell 1. A baffle block 24 is provided in the horizontal end of the T-shaped groove 12, which is used to cooperate with the downward movement of the F-shaped block 25, so that the space between the pressure transmission block 54 and the annular stress sheet 52 can be communicated with the rectangular groove 13, so as to realize the interaction between the medium to be detected and the annular stress sheet 52. The F-shaped block 25 is fixedly connected to the baffle block 24, and the lower end of the baffle block 24 is connected to the circular slide groove 232 in a limited sliding connection. A pressure transmission block 54 is provided above the lower horizontal end of the F-shaped block 25, and an elastic connector 53 is fixedly connected to the upper end surface of the pressure transmission block 54. The elastic connector 53 is retractable and has a spring inside, so that after a single pressure detection is completed, the pressure transmission block 54 can automatically reset. When the sensor is in When in a vertical state, after a single pressure detection is completed, the pressure transmission block 54 can be reset by its own gravity. When the sensor is in a horizontal state, at this time, after the pressure detection work is completed, the pressure transmission block 54 cannot be reset by its own gravity, and the elastic connector 53 is required to provide a reset force. One end of the elastic connector 53 is in contact with the bottom of the annular stress sheet 52, so that there is no loss of pressure during the transmission process, thereby improving the detection accuracy. The distance between the upper and lower horizontal ends of the F-shaped block 25 is equal to the sum of the vertical height of the pressure transmission block 54 and the length of the maximum extrusion deformation of the elastic connector 53, thereby ensuring that the elastic connector 53 will not be blocked by the upper horizontal end of the F-shaped block 25 when being squeezed, thereby ensuring the reliability of the pressure detection work. At the same time, increasing the maximum pressurized deformation length of the elastic connector 53 can increase the pressure detection range.

[0052] The use principle of a temperature and pressure integrated sensor structure provided by the present invention is as follows:

[0053] The impurities on the surface of the temperature detection rod 71 are cleaned by rotating the annular screw block 21 downward, the annular screw block 21 drives the L-shaped frame 22 to rotate downward, the L-shaped frame 22 drives the round block 23 to rotate downward, the round block 23 drives the cleaning block 233 to rotate downward, and scrapes the impurities attached to one end of the temperature detection rod 71. Most of the scraped impurities fall from the circular groove 231, and a small part falls from the gap between the round block 23 and the housing 1.

[0054] The pressure detection mode is switched by the round block 23 rotating downward, driving the baffle block 24 to move downward, and the baffle block 24 drives the F-shaped block 25 to move downward. When the horizontal end above the F-shaped block 25 contacts the pressure transmission block 54 and starts to drive the pressure transmission block 54 to move downward, until the space between the pressure transmission block 54 and the annular stress sheet 52 is connected to the rectangular groove 13, the medium to be detected flows into the space between the pressure transmission block 54 and the annular stress sheet 52 and squeezes the annular stress sheet 52. The annular stress sheet 52 changes its resistance through deformation, thereby detecting the pressure value. This mode switching can be used for the detection of non-corrosive media or media with less impurities. In addition, when the pressure transmission block 54 is damaged and there is no new spare part, it can also be detected through this mode, thereby improving the reliability and flexibility of the sensor.

[0055] The internal components of the sensor are disassembled by the pressure transmission block 54 driving the temperature detection rod 71 to move downward when it moves downward, the temperature detection rod 71 drives the temperature detection part 7 to move downward, the electrical pin 6 of the temperature detection part 7 drives the pressure detection part 5 to move downward, the pressure detection part 5 drives the control circuit board 4 to move downward, and the control circuit board 4 drives the electrical connector 3 to move downward along the electrical connector groove 11 until the annular screw block 21 is no longer engaged with the teeth on the outer shell 1, and the internal electrical components can be directly taken out. When the removed electrical components need to replace the pressure transmission block 54, the pressure transmission block 54 can be replaced by screwing the temperature detection rod 71 downward. When the annular screw block 21 is rotated downward, the temperature detection rod 71 and the annular stress sheet 52 also move downward. While ensuring that the annular screw block 21 is engaged with the teeth on the outer shell 1, the positions of the temperature detection rod 71 and the annular stress sheet 52 are changed, and the temperature and pressure at different depths in the liquid medium can be detected.
