[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0055] It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

In addition, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0058] In the description of the embodiments of the present application, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0059] With reference to Figures 1 to 9 The valve lock 100 provided by the embodiments of the present application comprises a housing 10, a transmission shaft 20, an electronic unlocking mechanism 30 and a detection mechanism 40. The transmission shaft 20 is rotatably arranged in the housing 10, and is used to connect a valve. The electronic unlocking mechanism 30 comprises a motor 31 and a locking member 32, the locking member 32 has a first position for locking the transmission shaft 20 and a second position for releasing the transmission shaft 20, and the motor 31 is used to drive the locking member 32 to move from the first position to the second position. The detection mechanism 40 is arranged in the housing 10, and comprises a detected member 41 and a detection member 42, the detected member 41 is in transmission connection with the transmission shaft 20, and is configured to rotate with the transmission shaft 20, and the detection member 42 is configured to detect the rotation angle and / or the number of rotation circles of the detected member 41, so as to detect the rotation angle of the transmission shaft 20.

[0060] The housing 10 has a containing space for containing the transmission shaft 20, the electronic unlocking mechanism 30 and the detection mechanism 40 and the like.

[0061] For example, the housing 10 can comprise a base 11 and a top cover 12 arranged on the base 11, and the base 11 and the top cover 12 enclose a containing space for containing the transmission shaft 20, the electronic unlocking mechanism 30 and the detection mechanism 40.

[0062] The transmission shaft 20 is rotatably arranged in the housing 10, and is used to connect a valve. The rotation of the valve can drive the transmission shaft 20 to rotate synchronously.

[0063] For example, the transmission shaft 20 can be fixedly connected with a connecting shaft of the valve, wherein the connecting shaft is a component in the valve for connecting a ball and a rotating handle, and when the rotating handle is rotated, the connecting shaft and the ball rotate synchronously to open or close the valve or adjust the opening degree (rotation angle) of the valve.

[0064] With reference to Figure 2 For example, one end of the transmission shaft 20 is rotatably mounted on the base 11, and the other end is exposed from the top cover 12 to facilitate the connection with the valve.

[0065] The electronic unlocking mechanism 30 comprises a motor 31 and a locking member 32, the locking member 32 has a first position for locking the transmission shaft 20 and a second position for releasing the transmission shaft 20, and the motor 31 is used to drive the locking member 32 to move from the first position (Figure 3 moves to a second position (as shown) from the first position. Figure 4 moves to a second position (as shown) from the first position.

[0066] The locking member 32 can lock the transmission shaft 20 so that the valve lock 100 is locked, and the transmission shaft 20 cannot rotate, and the valve cannot rotate. The locking member 32 can release the transmission shaft 20 so that the valve lock 100 is unlocked, and the transmission shaft 20 can rotate with the valve.

[0067] When the valve lock 100 needs to be unlocked, the motor 31 drives the locking member 32 to move from the first position to the second position, so that the locking member 32 releases the transmission shaft 20.

[0068] The detection mechanism 40 includes a measured member 41 and a detection member 42. The measured member 41 is in driving connection with the transmission shaft 20, and is configured to rotate with the transmission shaft 20. The detection member 42 is configured to detect the rotation angle and / or the number of rotations of the measured member 41, so as to detect the rotation angle of the transmission shaft 20.

[0069] When the valve is rotated, the transmission shaft 20 rotates with the valve, and the measured member 41 rotates with the transmission shaft 20, that is, the valve, the transmission shaft 20 and the measured member 41 can rotate synchronously.

[0070] The detection member 42 can detect the rotation angle and / or the number of rotations of the measured member 41, so as to detect the rotation angle of the transmission shaft 20, and further detect the state of the valve. The state of the valve may, for example, be the opening degree of the valve, the opening or closing of the valve, etc. As an example, the opening degree of the valve can be calculated by a microprocessor based on the rotation angle and / or the number of rotations of the measured member 41 detected by the detection member 42.

[0071] Therefore, the valve lock 100 of the embodiment of the present application has the functions of automatic unlocking and valve state detection by the built-in detection mechanism 40 and electronic unlocking mechanism 30, and manual inspection and recording are not required, so as to reduce the risk of accidents and labor costs.

[0072] In some embodiments, with reference to Figure 2 The measured member 41 is a pole magnetic steel. The detection member 42 is a magnetic induction sensor, and the position of the magnetic induction sensor corresponds to the position of the pole magnetic steel.

[0073] The magnetic induction sensor can detect the change of the magnetic field when the pole magnetic steel rotates, so as to accurately detect the rotation angle and / or the number of rotations of the transmission shaft 20.

[0074] The position of the magnetic induction sensor corresponds to the position of the pole magnetic steel. The magnetic induction sensor can be arranged opposite to the pole magnetic steel, i.e. face to face. It can be understood that the position of the magnetic induction sensor and the position of the pole magnetic steel can also allow installation errors, as long as the magnetic induction sensor can accurately detect the magnetic field change when the pole magnetic steel rotates. The magnetic induction sensor can be a Hall sensor.

[0075] By taking the pole magnetic steel as the measured member 41 and the magnetic induction sensor as the detection member 42, contactless and high-precision angle measurement can be achieved, and the reliability of valve state detection can be improved.

[0076] In some possible embodiments, the angle detection of the transmission shaft 20 can also be other types of detection mechanisms. For example, inductive sensors, capacitive sensors, laser measurement, etc. As an example, the measured member 42 can be a reflective member with a reflective surface and a scale, and the detection member 42 can be a laser sensor, which calculates the rotation angle and / or the number of turns of the transmission shaft 20 according to the angle change of the light reflected by the measured member 42.

[0077] In some embodiments, referring to Figure 2 , the transmission shaft 20 is fixed with a first gear 21. The detection mechanism 40 further includes a second gear 43, which is engaged with the first gear 21, and the measured member 41 is fixed to the second gear 43 and arranged coaxially with the second gear 43.

[0078] The measured member 41 is arranged coaxially with the second gear 43, so that the center of rotation of the measured member 41 coincides with the center of rotation of the second gear 43.

[0079] The first gear 21 is a driving wheel, and the second gear 43 is a driven wheel. The first gear 21 rotates synchronously with the transmission shaft 20, thereby driving the second gear 43 and the measured member 41 to rotate synchronously, and thus the measured member 41 is drivingly connected with the transmission shaft 20 through the engagement of the second gear 43 with the first gear 21.

[0080] In some cases, the opening (angle) range of the valve can be small, resulting in a small rotation angle of the transmission shaft 20. If the rotation angle of the measured member 41 is too small, it can not be measured accurately or at all. Of course, if the rotation angle of the measured member 41 is too large, i.e. the rotation speed is too fast, it can also not be measured accurately or at all.

[0081] To this end, the measured member 41 is drivingly connected with the transmission shaft 20 through gear transmission, and the gear ratio of the first gear 21 and the second gear 43 can be designed to achieve appropriate measurement angle and / or measurement speed of the measured member 41, thereby improving the measurement accuracy.

[0082] In some possible embodiments, the manner in which the measured member 41 is in driving connection with the transmission shaft 20 to achieve synchronous rotation can also be various, such as belt transmission, chain transmission, friction transmission, etc.

[0083] In some embodiments, the second gear 43 comprises a gear body 431 and a rotating shaft 432 arranged at one side of the gear body 431 in the thickness direction, and the rotating shaft 432 is provided with a receiving groove 432a, and the measured member 41 is arranged in the receiving groove 432a.

[0084] As an example, referring to Figure 2 and Figure 9 , the gear body 431 is engaged with the first gear 21, and the rotating shaft 432 is coaxial with the gear body 431. The second gear 43 is rotatably installed on a gear mounting seat 44 arranged in the base 11, and the gear mounting seat 44 is provided with a through hole, and the rotating shaft 432 is arranged in the through hole, and the measured member 41 (the pole magnetic steel) is arranged in the receiving groove 432a of the rotating shaft 432. The main control board 60 is fixed on the gear mounting seat 44, and the detection member 42 (the Hall sensor) can be integrated on the main control board 60 and opposite to the measured member 41 (the pole magnetic steel).

[0085] Of course, the second gear 43 can also be directly rotatably installed on the base 11, and the gear mounting seat 44 is omitted. The detection member 42 (the Hall sensor) can also not be integrated on the main control board 60, but be a separate component.

[0086] In this way, the measured member 41 is arranged in the receiving groove 432a, and the installation reliability can be improved.

[0087] In some embodiments, referring to Figure 2 , the valve lock 100 further comprises an indication disc 51 for indicating the unlocking state, the indication disc 51 is linked with the locking member 32, and the indication disc 51 is configured to switch between a third position and a fourth position; wherein when the locking member 32 is located at the first position, the indication disc 51 is located at the third position, and when the locking member 32 is located at the second position, the indication disc 51 is located at the fourth position; the shell 10 is provided with a visual window 101 for observing the indication disc 51.

[0088] The indication disc 51 linked with the locking member 32 can be understood as that the indication disc 51 moves with the locking member 32. In other words, when the locking member 32 is switched from the first position to the second position, the locking member 32 drives the indication disc 51 to switch from the third position to the fourth position, and when the locking member 32 is switched from the second position to the first position, the locking member 32 drives the indication disc 51 to switch from the fourth position to the third position.

[0089] As an example, when the locking member 32 is in the first position, the transmission shaft 20 is locked, at this time, the indicator disc 51 is in the third position, in the third position, the indicator disc 51 avoids the visual window 101 to expose it, i.e. the visual window 101 cannot see the indicator disc 51, then it can be determined that the valve lock 100 is in the locked state. When the locking member 32 is in the second position, the transmission shaft 20 is released, at this time, the indicator disc 51 is in the fourth position, in the fourth position, the indicator disc 51 blocks the visual window 101, then it can be determined that the valve lock 100 is in the unlocked state. By the way that the indicator disc 51 blocks or avoids the visual window 101, the unlocked state and the locked state of the valve lock 100 can be observed intuitively.

[0090] However, the visual way of the unlocked state and the locked state of the valve lock 100 according to the present application is not limited to the above way.

[0091] As another example, when the indicator disc 51 switches between the third position and the fourth position, the indicator disc 51 can block the visual window 101, and different parts of the indicator disc 51 correspond to the position of the visual window 101, so that the unlocked state and the locked state of the valve lock 100 can be observed intuitively. For example, when the indicator disc 51 is in the third position, the indicator disc 51 has a first part corresponding to the locked state, and the first part corresponds to the position of the visual window 101; when the indicator disc 51 is in the fourth position, the indicator disc 51 has a second part corresponding to the unlocked state, and the second part corresponds to the position of the visual window 101. The first part and the second part can be marked with different words, different symbols, different colors, or the first part and the second part have different shapes, etc.

[0092] By the linkage of the indicator disc 51 and the locking member 32, the shell 10 is provided with the visual window 101 for observing the indicator disc 51, so that the unlocked state and the locked state of the valve lock 100 can be observed intuitively, and the risk of accidents caused by misjudgment is further reduced.

[0093] In some embodiments, the indicator disc 51 is slidably arranged in the shell 10; the valve lock 100 further comprises a knob 52 connected to the indicator disc 51 and the locking member 32.

[0094] When the locking member 32 switches from the first position to the second position, the knob 52 drives the indicator disc 51 to switch from the third position to the fourth position; when the locking member 32 switches from the second position to the first position, the knob 52 drives the indicator disc 51 to switch from the fourth position to the third position.

[0095] As an example, referring to Figure 2The indicating disc 51 can be slidably arranged in an indicating disc mounting base 53, the indicating disc mounting base 53 being fixed to the base 11 and provided with a sliding channel slidably connected with the indicating disc 51, and the indicating disc 51 is provided with a sliding groove at the bottom, one end of the actuating member 52 is fixedly connected with the locking member 32, and the other end can actuate the indicating disc 51 in the sliding groove.

[0096] Of course, the indicating disc 51 can also be directly slidably arranged in the base 11.

[0097] In addition, the indicating disc 51 can also have multiple ways to switch between the third position and the fourth position, and is not limited to the above-mentioned sliding mode. For example, the indicating disc 51 can also be switched between the third position and the fourth position in a rotating manner.

[0098] In some embodiments, the electronic unlocking mechanism 30 further comprises an elastic member 33 connected with the locking member 32, for driving the locking member 32 to move from the second position to the first position.

[0099] The elastic member 33 drives the locking member 32 to move from the second position to the first position, so that the locking member 32 locks the transmission shaft 20, and the valve lock 100 is in the locked state.

[0100] The elastic member 33 can be fixedly connected or abutted with the locking member 32.

[0101] The elastic member 33 can drive the locking member 32 to move from the second position to the first position by its elastic force, or can drive the locking member 32 to move from the second position to the first position by its elastic restoring force.

[0102] As an example, referring to Figure 2 and Figure 3 The elastic member 33 is a torsion spring, which drives the locking member 32 to move from the second position to the first position by the elastic force of the torsion spring.

[0103] The elastic member 33 drives the locking member 32 to move from the second position to the first position, so that the locking member 32 flexibly locks the transmission shaft 20, and the valve lock 100 is in the locked state, which is simple and reliable.

[0104] It is worth noting that the driving mode of the locking member 32 moving from the second position to the first position to achieve locking can also be other modes, such as being driven by the motor 31 if necessary, i.e. the motor 31 can also drive the locking member 32 to achieve the locking and unlocking of the valve lock 100.

[0105] In some embodiments, the third gear 22 is fixed on the transmission shaft 20; the locking member 32 is provided with two, each of which is rotatably arranged in the housing 10, each of which comprises a first tooth portion 32a and a second tooth portion 32b, the first tooth portion 32a being used for engaging with the third gear 22 to lock the transmission shaft 20; the second tooth portions 32b of the two locking members 32 are engaged with each other to make the two locking members 32 rotate synchronously.

[0106] The synchronous rotation of the two locking members 32 makes the first tooth portions 32a of the two locking members 32 approach each other to engage with the third gear 22 respectively to lock the transmission shaft 20; the synchronous rotation of the two locking members 32 can also make the first tooth portions 32a of the two locking members 32 move away from each other synchronously to disengage from the third gear 22 respectively to release the transmission shaft 20.

[0107] As an example, referring to Figures 2 to 4 , each of the locking members 32 comprises a first lever portion 3211 and a second lever portion 3212, the first tooth portion 32a being arranged on the first lever portion 3211, and the second tooth portion 32b being arranged at a connecting position (for example, a middle position) between the first lever portion 3211 and the second lever portion 3212. The first lever portion 3211 and the second lever portion 3212 have an included angle therebetween. Each of the locking members 32 is rotatably mounted on a fixed plate 323 Figure 3 , and each of the locking members 32 can rotate about a rotation center of the second tooth portion 32b. One end of the elastic member 33 is fixed to the fixed plate 323, and the other end can abut against the second lever portion 3212 of one of the locking members 32 to drive the first lever portions 3211 of the two locking members 32 to approach each other synchronously and lock the transmission shaft 20. The motor 31 can drive the second lever portion 3212 of one of the locking members 32 to rotate to make the first lever portions 3211 of the two locking members 32 move away from each other synchronously and release the transmission shaft 20.

[0108] By engaging the two locking members 32 with the third gear 22 on the transmission shaft 20 respectively, the transmission shaft 20 can be locked at any position to realize stepless locking; by synchronous rotation of the two locking members 32, the driving is more convenient and reliable.

[0109] In some embodiments, the electronic unlocking mechanism 30 further comprises a fourth gear 34 and a fifth gear 35, the fourth gear 34 being connected with a rotation shaft of the motor 31; the fifth gear 35 being engaged with the fourth gear 34, and the fifth gear 35 being provided with a first limiting boss 351; wherein the first limiting boss 351 is used for pushing the locking member 32 to move from a first position Figure 3 to a second position Figure 4 , and the fourth gear 34 and the fifth gear 35 are both bevel gears.

[0110] As an example, referring to Figures 2 to 4 , the motor 31 can be fixed to the motor fixing seat 36, the first limiting boss 351 is eccentrically arranged on the fifth gear 35, the motor 31 drives the fourth gear 34 and the fifth gear 35 to rotate (for example, clockwise), the first limiting boss 351 swings around the rotation center of the fifth gear 35 to push the locking piece 32 to move from the position shown in Figure 3 to the position shown in Figure 4 , so as to realize unlocking. The motor 31 drives the fourth gear 34 and the fifth gear 35 to rotate (for example, counterclockwise), the first limiting boss 351 swings reversely around the rotation center of the fifth gear 35, so that the first limiting boss 351 is separated from the locking piece 32, the locking piece 32 is driven by the elastic piece 33 to move from the position shown in Figure 4 to the position shown in Figure 3 , so as to realize locking.

[0111] The motor 31 cooperates with the two gears (the fourth gear 34 and the fifth gear 35) to drive the locking piece 32 to move from the first position to the second position, the moving speed of the locking piece 32 pushed by the first limiting boss 351 can be reasonably configured, and the unlocking and locking are more stable; the two gears are bevel gears, and the layout is more reasonable.

[0112] In some embodiments, referring to Figures 1 to 4 , the valve lock 100 further comprises: a spring pin mounting seat 64 arranged in the shell 10; a spring pin 65 arranged in the spring pin mounting seat 64 in an extendable and retractable manner, the spring pin 65 extends out of the spring pin mounting seat 64 to limit the locking piece 32 at the position shown in Figure 3 ; the spring pin 65 retracts into the spring pin mounting seat 64 to release the limitation on the locking piece 32; the fifth gear 35 is further provided with a second limiting boss 352 (shown in Figure 7 ), the second limiting boss 352 is used for pressing the spring pin 65 to make the spring pin 65 retract into the spring pin mounting seat 64; after the second limiting boss 352 presses the spring pin 65, the first limiting boss 351 pushes the locking piece 32 to move from the first position to the second position.

[0113] The spring pin 65 extends out of the spring pin mounting seat 64, the spring pin 65 is located on the rotation path of the locking piece 32, and can resist the locking piece 32 to limit the locking piece 32 at the first position. The spring pin 65 retracts into the spring pin mounting seat 64 to release the limitation on the locking piece 32, and the locking piece 32 can be driven.

[0114] When it is necessary to unlock, the fifth gear 35 rotates, the second limiting boss 352 presses the elastic pin 65 first, so that the elastic pin 65 releases the restriction on the locking piece 32, the fifth gear 35 continues to rotate, the first limiting boss 351 reaches the locking piece 32 and pushes the locking piece 32 to move from the first position to the second position, thereby achieving unlocking.

[0115] As an example, a spring can be connected between the elastic pin 65 and the elastic pin mounting seat 64, the outer peripheral wall of the elastic pin 65 can be provided with a protrusion, and the second limiting boss 352 is eccentrically arranged on the fifth gear 35 and retracts the elastic pin 65 into the elastic pin mounting seat 64 by pressing the protrusion.

[0116] Through the retractable elastic pin 65, the locking piece 32 can be limited and restricted in the first position, and even in the case of failure of the elastic member 33, reliable locking can be achieved.

[0117] In some embodiments, with reference to Figure 2 , Figure 6 and Figure 7 , the valve lock 100 further comprises a main control board 60, a first micro switch 61 and a third micro switch 62; the first micro switch 61 and the third micro switch 62 are respectively electrically connected with the main control board 60; the fifth gear 35 is further provided with a third limiting boss 353, and the motor 31 is electrically connected with the main control board 60; in the second position, the locking piece 32 is in contact with the third micro switch 62, the main control board 60 controls the motor to stop rotating, and the first limiting boss 351 abuts against the locking piece 32; after the first limiting boss 351 releases the locking piece 32, the third limiting boss 353 is in contact with the first micro switch 61, and the main control board 60 controls the motor 31 to stop rotating.

[0118] In the second position, the locking piece 32 releases the transmission shaft 20, and the locking piece 32 is in contact with the third micro switch 62, the main control board 60 controls the motor to stop rotating, and the first limiting boss 351 abuts against the locking piece 32, thereby keeping the locking piece 32 in the second position.

[0119] After the first limiting boss 351 releases the locking piece 32, the third limiting boss 353 is in contact with the first micro switch 61. It can be understood that the first limiting boss 351 releases the locking piece 32 at the same time, and the third limiting boss 353 is in contact with the first micro switch 61. It can also be understood that the first limiting boss 351 releases the locking piece 32 and continues to rotate for a short distance, and the third limiting boss 353 is in contact with the first micro switch 61, so as to ensure that the locking piece 32 completely locks the transmission shaft 20.

[0120] When unlocking is needed, the fifth gear 35 rotates to drive the first limiting boss 351 to move close to the locking piece 32, and push the locking piece 32 to move from the first position to the second position to release the transmission shaft 20, at this time the locking piece 32 is in contact with the third micro switch 62, and the main control board 60 controls the motor to stop rotating, so that the first limiting boss 351 abuts against the locking piece 32 to keep the locking piece 32 in the second position;

[0121] When locking is needed, the fifth gear 35 rotates to drive the first limiting boss 351 to move away from the locking piece 32, and when the first limiting boss 351 releases the locking piece 32, the third limiting boss 353 is in contact with the first micro switch 61, and the main control board 60 controls the motor 31 to stop rotating.

[0122] When unlocking is needed again, the motor 31 can be started in place to quickly push the locking piece 32 to move from the first position to the second position.

[0123] Therefore, through the setting of the first micro switch 61 and the third micro switch 62, the motor 31 can be controlled to stop rotating in time, unnecessary stroke of the first limiting boss 351 during unlocking and locking is reduced, unlocking and locking efficiency is improved, and electric energy can be saved; in addition, the risk of motor burning due to the first limiting boss 351 always rotating to contact other parts (such as the end of the locking piece 32 close to the transmission shaft 20) can be prevented.

[0124] In some embodiments, referring to Figure 2 and Figure 5 , the valve lock 100 further comprises a mechanical unlocking and locking mechanism 70, the mechanical unlocking and locking mechanism 70 comprising: a lock body 71 arranged in the shell 10; a mechanical lock cylinder 72 rotatably arranged in the lock body 71; wherein the mechanical lock cylinder 72 is linked with the locking piece 32, and rotation of the mechanical lock cylinder 72 can drive the locking piece 32 to move from the first position to the second position.

[0125] The mechanical lock cylinder 72 is used for inserting a key, and the key can be used to rotate the mechanical lock cylinder 72 to drive the locking piece 32 to move from the first position to the second position, thereby achieving unlocking.

[0126] By setting the mechanical unlocking and locking mechanism 70, the valve lock 100 not only has an electronic unlocking and locking function, but also has a mechanical unlocking and locking function, and when the electronic unlocking and locking mechanism 30 fails, unlocking can be realized through the mechanical unlocking and locking mechanism 70, thereby improving the unlocking and locking reliability.

[0127] In some embodiments, the mechanical unlocking and locking mechanism 70 further comprises: a lock piece 73 connected with the mechanical lock cylinder 72; an unlocking slide 74 movably arranged in the shell 10; wherein rotation of the lock piece 73 can drive the unlocking slide 74 to move to drive the locking piece 32 to move from the first position to the second position.

[0128] The mechanical lock cylinder 72 rotates to drive the lock piece 73 to rotate synchronously, and the lock piece 73 drives the unlocking slide piece 74 to move, thereby driving the locking member 32 to move from the first position to the second position.

[0129] As an example, the lock piece 73 can be connected with the mechanical lock cylinder 72 through a connecting shaft 75. The unlocking slide piece 74 can be slidingly arranged in the motor fixing seat 36, which is fixed to the base 11 and is provided with a sliding groove for slidingly cooperating with the unlocking slide piece 74. The unlocking slide piece 74 is provided with a through hole 741, and the lock piece 73 enters the through hole 741 when rotating and drives the unlocking slide piece 74 to move, so that the unlocking slide piece 74 interferes with the locking member 32 to drive the locking member 32 to move from the first position to the second position, thereby achieving unlocking.

[0130] The mechanical lock cylinder 72 can easily move the locking member 32 from the first position to the second position through cooperation with the unlocking slide piece 74 and the locking member 32, thereby achieving unlocking.

[0131] In some embodiments, the two locking members 32 are a first locking member 321 and a second locking member 322; the motor 31 is in driving connection with the first locking member 321, and the mechanical lock cylinder 72 is in driving connection with the second locking member 322; when the motor 31 drives the locking member 32 to release the transmission shaft 20, the first locking member 321 is the driving part, and the second locking member 322 is the driven part; when the mechanical lock cylinder 72 drives the locking member 32 to release the transmission shaft 20, the second locking member 322 is the driving part, and the first locking member 321 is the driven part.

[0132] When unlocking through the electronic unlocking mechanism 30, the motor 31 can drive the first locking member 321 to rotate, and the first locking member 321 as the driving part drives the second locking member 322 to rotate synchronously, thereby releasing the transmission shaft 20 by the first locking member 321 and the second locking member 322, and achieving unlocking. When unlocking through the mechanical unlocking mechanism 70, the mechanical lock cylinder 72 can drive the second locking member 322 to rotate, and the second locking member 322 as the driving part drives the first locking member 321 to rotate synchronously, thereby releasing the transmission shaft 20 by the first locking member 321 and the second locking member 322, and achieving unlocking.

[0133] Therefore, the electronic unlocking mechanism 30 and the mechanical unlocking mechanism 70 do not interfere with each other when unlocking, thereby improving the unlocking reliability.

[0134] In some embodiments, when unlocking, the motor 31 and the mechanical lock cylinder 72 can also drive the same locking member to move from the first position to the second position at the same time.

[0135] In some embodiments, with reference to Figure 2 and Figure 6The valve lock 100 also includes a second microswitch 63, which is electrically connected to the main control board 60. In the first position, the locking member 32 contacts the second microswitch 63, causing the main control board 60 to send a locking signal. For example, locking and unlocking signals can be sent to terminals such as mobile phones and control consoles.

[0136] This allows for timely acquisition of the valve lock status 100, reducing the risk of misoperation.

[0137] Below, refer to Figures 1 to 9 A specific example of an embodiment of this application will be described below.

[0138] This application provides a valve lock 100, specifically a valve lock that integrates valve status detection and locking / unlocking. The valve lock 100 may include a base 11, a top cover 12, a transmission shaft 20, a drive gear (first gear 21), a locking gear (third gear 22), a battery compartment cover 103, a viewing window 101, etc.

[0140] The drive shaft 20 is used to rotate synchronously with the valve shaft. The drive shaft 20 and the drive gear (first gear 21) are fixed by a key. The polarity magnet (test piece 41) and the driven gear (second gear 43) are fixed. When the valve rotates, the drive gear (first gear 21) drives the driven gear (second gear 43) to rotate, thereby causing the polarity magnet (test piece 41) to rotate. The sensor (detector 42) can identify the rotation angle and number of rotations of the polarity magnet (test piece 41).

[0141] The valve lock 100 also includes a motor mounting bracket 36. Figure 5 As shown), fixing plate 323 ( Figure 3 (As shown), motor 31, drive bevel gear (fourth gear 34), driven bevel gear (fifth gear 35), first locking element 321, second locking element 322, torsion spring (elastic element 33), spring pin 65, spring pin mounting seat 64, indicator dial 51, indicator dial mounting seat 53, and toggle element 52.

[0142] The motor 31 is connected to the drive bevel gear. The rotation of the motor 31 drives the bevel gear to rotate, which in turn drives the driven bevel gear. The driven bevel gear is provided with a first limiting boss 351. When it rotates, the first limiting boss 351 pushes the first locking member 321.

[0143] The first locking member 321 and the second locking member 322 have a rack feature (first tooth part 32a) at one end and a gear feature (second tooth part 32b) at the middle part. The two locking members are driven by the gear form engagement to make the two locking members act simultaneously. When the lock is closed, the two locking members are pushed against the locking gear (third gear 22) by the torsion spring flexible locking, so as to lock the transmission shaft 20. When the lock is unlocked, the motor 31 drives the bevel gear to push the two locking members to open simultaneously, so as to release the transmission shaft 20.

[0144] The spring pin 65 serves as a locking limiting mechanism. When the first locking member 321 reaches the locking position (first position), the spring pin 65 will automatically extend to limit the opening of the two locking members. At this time, the valve lock 100 is in a fully locked state. In the unlocking process, the second limiting boss 352 on the driven bevel gear cooperates with the spring pin 65. When rotating, the spring pin 65 is first pressed down to release the limitation of the two locking members, and then the first limiting boss 351 pushes the first locking member 321 to move from the locking position to the unlocking position.

[0145] The actuator 52 is fixed on the first locking member 321, and the indicator disc 51 for indicating the unlocking state is provided with a sliding groove matched with the actuator 52. The actuator 52 pushes the indicator disc 51 to reach or move away from the visible window 101 in the process of rotating the first locking member 321.

[0146] The valve lock 100 further comprises a mechanical lock cylinder 72, a connecting shaft 75, a lock piece 73, and an unlocking slide 74.

[0147] The mechanical lock cylinder 72 is installed on the lock body 71, and the unlocking slide 74 is placed in the sliding groove of the motor fixing seat 36. When the mechanical key is inserted into the mechanical lock cylinder 72 to unlock, the mechanical lock cylinder 72 and the connecting shaft 75 rotate to drive the lock piece 73 to rotate. The lock piece 73 will be inserted into the through hole 741 of the unlocking slide 74 and push the unlocking slide 74 in the process of rotating. The unlocking slide 74 will push the second locking member 322 to rotate, thereby synchronously driving the first locking member 321 to rotate, so as to achieve the purpose of unlocking. When the lock is closed, the mechanical lock cylinder 72 and the connecting shaft 75 rotate to drive the lock piece 73 to rotate in the reverse direction, so that the unlocking slide 74 is released. The two locking members are locked with the locking gear to lock the transmission shaft 20 through the torsion spring flexible locking. After the lock is closed, the spring pin 65 extends.

[0148] The valve lock 100 further comprises an unlocking micro switch (third micro switch 62), a locking micro switch (second micro switch 63), a motor release micro switch (first micro switch 61), and a wake-up button 80.

[0149] There are two trigger points for installing screws on the second locking member 322, and micro switches (second micro switch 63 and third micro switch 62) are arranged in the corresponding positions (first position and second position) of the unlocking. In addition, after the motor 31 rotates to release the first locking member 321, it should not continue to idle, and the motor release micro switch is used to control the motor 31 to stop.
