[0039] Embodiment 1

[0040] As Figures 1 to 4 shown, the present utility model provides a sensor protection device and a biological detector. The biological detector includes a main body, a sensor 100, and a sensor protection device. Both the sensor 100 and the sensor protection device are provided on the main body. In this embodiment, the biological detector is used as a measuring instrument in a bioreactor; the biological detector has a sensor 100, the sensor 100 has an outer extending portion extending along a first direction, the sensor protection device is used to protect the outer extending portion; the cross-section of the outer extending portion of the sensor 100 is circular.

[0041] The sensor protection device includes a fixing member 10, a protection member 20 and a limiting member 40. The fixing member 10 is arranged on the main body of the biological detector; the protection member 20 includes a connecting portion 21 and a protection portion 22. The protection portion 22 is connected to the connecting portion 21. The connecting portion 21 is rotatably arranged on the fixing member 10, and the protection portion 22 is used to shield the sensor 100; the limiting member 40 is used to limit the rotation of the protection member 20.

[0042] By rotating the protection member 20, the protection portion 22 is rotated to the position of the sensor 100 to shield the sensor 100, avoiding damage or accidental touch of the sensor 100 and improving the detection accuracy; the protection portion 22 shields the sensor 100, reducing the limitation on the structural type of the sensor 100 and improving the versatility; when the sensor 100 needs to be disassembled, replaced, only need to rotate the protection member 20 to make the protection portion 22 away from the sensor 100, and limit it through the limiting member 40, without removing the entire sensor protection device, effectively simplifying the disassembly and assembly steps and reducing the operation difficulty.

[0043] In this embodiment, the top end of the fixing member 10 is connected to the main body. There is a notch at the middle position of the bottom end of the fixing member 10. A part of the connecting portion 21 of the protection member 20 is inserted into the notch, and the protection portion 22 extends along the first direction; the connecting portion 21 is rotatably arranged on the fixing member 10 through a rotating shaft 30. The rotating shaft 30 is arranged at the notch position. The rotating shaft 30 passes through the fixing member 10 and the protection member 20 and is locked by screwing with a locking member. By arranging a notch at the middle position of the bottom end of the fixing member 10, the connecting portion 21 can be inserted into the notch, and the side surface of the notch can play a limiting role when the protection member 20 rotates, ensuring that the protection member 20 does not deviate during the rotation process.

[0044] Preferably, the protection portion 22 is an arc-shaped plate, and the protection portion 22 forms a protection space with an opening for accommodating the sensor 100. In this embodiment, the cross-sectional shape of the protection portion 22 is three-quarters of an annular shape, and one side of the protection portion 22 has an opening; the inner diameter of the protection portion 22 is larger than the cross-sectional diameter of the extended part of the sensor 100. When the protection member 20 rotates to make the protection portion 22 gradually approach the sensor 100, the sensor 100 enters the protection space from the opening, and the protection portion 22 shields the sensor 100 from the side.

[0045] Specifically, the protection member 20 has a protection state of shielding the sensor 100. When the protection member 20 is in the protection state, the limiting member 40 is inserted into the fixing member 10 and the protection member 20 at the same time to limit the protection member 20; the protection member 20 also has an operation state of being away from the sensor 100. When the protection member 20 is in the operation state, the limiting member 40 is separated from the protection member 20.

[0046] In the protection state, the limiting member 40 is inserted into the fixing member 10 and the protection member 20 at the same time. Under the joint restriction of the rotating shaft 30 and the limiting member 40, the protection member 20 is relatively fixed to the fixing member 10, so that the protection part 22 stably shields the sensor 100. In the operation state, the limiting member 40 is separated from the protection member 20, so that the protection member 20 can rotate.

[0047] When it is necessary to disassemble, install and replace the sensor 100, only need to rotate the protection member 20 to make the protection part 22 away from the sensor 100. When the protection member 20 rotates a certain angle, the limiting member 40 is inserted into the fixing member 10 and the end protrudes from the surface of the fixing member 10 to block the protection member 20 from the side. After the protection member 20 moves away from the sensor 100, the protection member 20 has a tendency to swing downward under its own gravity. The end of the protection member 20 is blocked by the limiting member 40 and cannot swing downward. Therefore, the sensor 100 can be disassembled, installed, maintained and other operations without holding the protection member 20 by hand.

[0048] To install the limiting member 40, a first positioning hole 211 is provided on the connecting part 21. The limiting member 40 is inserted into the fixing member 10. The limiting member 40 can move along the axis direction of the first positioning hole 211 to be selectively inserted into the first positioning hole 211. By inserting the limiting member 40 into the fixing member 10 and moving the limiting member 40 to selectively insert it into the first positioning hole 211 of the connecting part 21, when the protection member 20 switches between the protection state and the operation state, the limiting member 40 can limit the protection member 20.

[0049] In this embodiment, the limiting member 40 is a spring pin. An installation groove and a second positioning hole 11 communicating with the installation groove are provided on the fixing member 10. The axis direction of the second positioning hole 11 is parallel or coincident with that of the first positioning hole 211. The spring pin includes a pin shaft and a spring. The spring is arranged in the installation groove. The pin shaft is inserted into the second positioning hole 11. The two ends of the spring are respectively connected to the pin shaft and the bottom of the installation groove.

[0050] By using the elastic force of the spring, the automatic reset of the pin shaft can be realized, and the insertion depth of the protection member 20 can also be ensured. When it is necessary to replace the sensor 100, the pin shaft is pulled out a small distance along the axis direction of the second positioning hole 11, so that the end of the pin shaft is pulled out from the first positioning hole 211 to release the protection member 20, and the protection member 20 can rotate relative to the fixing member 10. When it is necessary to protect the sensor 100, just insert the pin shaft into the first positioning hole 211 and the second positioning hole 11 at the same time. In other embodiments, the limiting member 40 can also be set as a limiting post, and the limiting member 40 is manually inserted and taken out.

[0051] In this embodiment, the setting position of the first positioning hole 211 is higher than the setting position of the rotating shaft 30; when the protective member 20 is in the protective state, the axial directions of the second positioning hole 11 and the first positioning hole 211 coincide; when the protective member 20 is in the operating state, the axial directions of the second positioning hole 11 and the first positioning hole 211 are parallel. By setting the position of the first positioning hole 211 higher than that of the rotating shaft 30, when the protective member 20 has a tendency to swing downward under its own gravity, the limiting member 40 is located above the protective member 20 to block the protective member 20. In other embodiments, multiple limiting members 40 can also be provided, and the setting positions of the limiting members 40 can also be adjusted according to actual situations.

[0052] The following is the specific use process of the sensor protection device:

[0053] As Figure 3 and Figure 4 shown, in the protective state, the protruding part of the sensor 100 is located within the protective space of the protective part 22, and the protruding part is located at the central position of the protective space. The protective part 22 surrounds the outside of the protruding part and maintains a certain gap from the protruding part. The protective part 22 protects the protruding part from the side to prevent the sensor 100 from being accidentally touched or damaged.

[0054] When the sensor 100 needs to be operated, pull the limiting member 40 out a short distance outward so that the end of the limiting member 40 is withdrawn from the first positioning hole 211 to release the protective member 20; after rotating the protective member 20 around the rotating shaft 30 by a certain angle, reset the limiting member 40; at this time, the end of the limiting member 40 protrudes from the surface of the fixing member 10 to limit the rotation of the protective member 20 from the side. Therefore, it is not necessary to remove the sensor protection device, nor is it necessary to hold the protective member 20 by hand, and operations such as disassembly, installation, and maintenance of the sensor 100 can be carried out.

[0055] After completing the operation and installing the sensor 100, pull the limiting member 40 out a short distance outward so that the protective member 20 rotates back to the protective state and reset the limiting member 40; at this time, the limiting member 40 is simultaneously inserted into the first positioning hole 211 and the second positioning hole 11 to limit the rotation of the protective member 20, thereby keeping the protective member 20 in the protective state.

[0056] Embodiment Two

[0057] Refer to Figures 1 to 4 , a notch is provided on the fixing member 10 of Embodiment One, and the protective member 20 is inserted into the notch, and then the rotating shaft 30 and the limiting member 40 are provided at the position of the notch. Compared with Embodiment One, refer to Figure 5, in the second embodiment, the fixing member 10 and the protection member 20 overlap and are rotatably connected at the overlapping position. Specifically, the top end of the fixing member 10 is connected to the main body, the bottom end of the fixing member 10 overlaps with the connecting portion 21, the rotating shaft 30 and the limiting member 40 are both arranged at the overlapping position, and the connecting portion 21 of the fixing member 10 and the protection member 20 is rotatably connected through the rotating shaft 30. The limiting member 40 sequentially passes through the fixing member 10 and the connecting portion 21; pulling the limiting member 40 outwards by a small distance so that the end portion of the limiting member 40 is drawn out from the connecting portion 21 can release the protection member 20; when the limiting member 40 is reset and simultaneously passes through the fixing member 10 and the connecting portion 21, the limiting member 40 restricts the rotation of the protection member 20, so that the protection member 20 maintains the protection state.

[0058] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention.
