[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides an active explosion-proof valve electrical control device, which has the following beneficial effects:

[0024] 1. The active explosion-proof valve electrical control device has two rotating explosion-proof plates arranged crosswise in a scissor shape, which enables the two rotating explosion-proof plates to be closed like scissors when the explosion-proof valve body is closed, and the cross-closing action can shear the gas to a certain extent. This closing method also has less resistance. Compared with the existing explosion-proof valve that uses a single plate to close, it has higher sensitivity and improves operating stability.

[0025] 2. When the active explosion-proof valve electrical control device detects excessive gas concentration, over-temperature, over-pressure, etc. through the set monitoring head, the controller will send a signal to the electric push rod. At this time, the output end of the electric push rod will drive the sliding gear seat to move backward in the slide rail frame. At this time, the small gear on the sliding gear seat can be disengaged from the large gear, and the large gear separated from the small gear will be rapidly rotated by the contraction force of the tension spring on the control rod, thereby driving the control rod and the large gear to rotate a predetermined angle about the axis of the second fixed column, so that the rotating control rod can drive the sliding column to move at the same time through the second slide groove. When the sliding column moves, it can drive the two rotating explosion-proof plates to rotate relative to each other through the two sliders thereon, so that the slider can slide in the first slide groove, thereby driving the two rotating explosion-proof plates to close quickly, effectively isolating potential dangerous gases or substances, preventing them from further spreading or causing greater safety accidents, and improving the safety of equipment and environment.

[0026] 3. The active explosion-proof valve electrical control device starts the electric push rod through the controller, and the electric push rod drives the sliding gear seat to move until the small gear is engaged with the large gear. At this time, the worm gear self-locking motor is started, and the output shaft of the worm gear self-locking motor drives the large gear and the control rod thereon to rotate through the small gear, thereby stretching and deforming the tension spring, so that the rotating control rod can open the two rotating explosion-proof panels. The entire opening process is completed by the automatic control of the electric push rod and the worm gear self-locking motor controlled by the controller, without manual operation, which simplifies the operation process and improves the convenience of operation.

[0027] 4. The active explosion-proof valve electrical control device has a self-locking function through the worm gear self-locking motor. It can keep the current position when the power supply is cut off, effectively preventing the rotating explosion-proof plate from accidentally closing due to external factors. This improves the stability and reliability of the entire system and also enhances the reliability of the mechanism.

[0028] 5. The active explosion-proof valve electrical control device, when the two rotating explosion-proof plates are closed, is set until the two rotating explosion-proof plates rotate to contact with the corresponding spring plates in the buffer assembly. At this time, the rotating explosion-proof plates will drive the spring plates to produce elastic deformation. The elastically deformed spring plates can offset a part of the force transmitted by the tension spring to the rotating explosion-proof plates until the rotating explosion-proof plates contact with the rubber buffer sleeves. At this time, the rubber buffer sleeves can produce plastic deformation, thereby offsetting the remaining impact force when the rotating explosion-proof plates are closed. This avoids excessive impact force when the rotating explosion-proof plates are closed, thereby reducing the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Furthermore, a tension spring 16 is fixedly connected between the fixed plate 4 and the control rod 10, and the tension spring 16 is used to drive the control rod 10 to close. The outer surface of the explosion-proof valve body 1 is fixedly connected with a slide rail frame plate 17, and a sliding gear seat 18 is slidably connected inside the slide rail frame plate 17. The electric push rod 25 is fixedly connected inside the slide rail frame plate 17, and the output end of the electric push rod 25 is fixedly connected to the sliding gear seat 18.

[0047] Furthermore, a small gear 19 is rotatably connected inside the sliding gear seat 18, and the small gear 19 is meshed with the large gear 13. A worm gear self-locking motor 20 is fixedly installed on the outer surface of the sliding gear seat 18. The worm gear self-locking motor 20 is a worm gear reduction motor with a certain self-locking property.

[0048] Furthermore, the output shaft of the worm gear self-locking motor 20 is fixedly connected and inserted into the pinion 19, and a housing 2 for protecting the operation of the transmission mechanism is fixedly installed on the outer surface of the flameproof valve body 1.

[0049] Furthermore, the third fixed column 21 in the buffer assembly is fixedly connected to the outer surface of the fixed plate 4, the spring plate 23 is fixedly connected to the outer surface of the third fixed column 21, the spring plate 23 is used to buffer the rotating explosion-proof plate 6, and the outer surface of the third fixed column 21 is fixedly sleeved with a rubber buffer sleeve 22 for shock absorbing the rotating explosion-proof plate 6.

[0050] Furthermore, the controller 3 in the monitoring control assembly is fixedly connected to the outer surface of the flameproof valve body 1, the controller 3 is electrically connected to the worm gear self-locking motor 20, and the controller 3 is electrically connected to the electric push rod 25;

[0051] The controller 3 is provided with a monitoring head 24 for detecting the gas condition in the flameproof valve body 1 , and the monitoring head 24 extends into the flameproof valve body 1 . The controller 3 is provided with a touch screen for controlling display parameters.

[0052] Furthermore, when the monitoring head 24 is used to monitor that the gas concentration exceeds the standard, the temperature exceeds the standard, the pressure exceeds the standard, etc., the controller 3 will send a signal to the electric push rod 25. At this time, the output end of the electric push rod 25 will drive the sliding gear seat 18 to move backward in the slide rail frame plate 17. At this time, the small gear 19 on the sliding gear seat 18 can be disengaged from the large gear 13, and the large gear 13 separated from the small gear 19 will be rapidly rotated by the contraction force of the tension spring 16 on the control rod 10, thereby driving the control rod 10 and the large gear 13 to rotate a predetermined angle about the axis of the second fixed column 12, so that the rotating control rod 10 can drive the sliding column 8 to move at the same time through the second slide groove 14. When the sliding column 8 moves, it can drive the two rotating explosion-proof panels 6 to rotate relative to each other through the two sliders 9 thereon, so that the slider 9 can slide in the first slide groove 7, thereby driving the two rotating explosion-proof panels 6 to close quickly, effectively isolating potential dangerous gases or substances, preventing them from further spreading or causing greater safety accidents, and improving the safety of equipment and environment.

[0053] Furthermore, when it is necessary to open, the electric push rod 25 is started through the controller 3, and the electric push rod 25 drives the sliding gear seat 18 to move until the small gear 19 is engaged with the large gear 13. At this time, the worm gear self-locking motor 20 is started, and the output shaft of the worm gear self-locking motor 20 drives the large gear 13 and the control rod 10 thereon to rotate through the small gear 19, thereby stretching and deforming the tension spring 16, so that the rotating control rod 10 can open the two rotating explosion-proof panels 6. The entire opening process is completed by the automatic control of the electric push rod 25 and the worm gear self-locking motor 20 controlled by the controller 3, without manual operation, simplifying the operation process and improving the convenience of operation.

[0054] Furthermore, the worm gear self-locking motor 20 has a self-locking function, which can maintain the current position when the power supply is stopped, effectively preventing the rotating explosion-proof panel 6 from being accidentally closed due to external factors, which improves the stability and reliability of the entire system and enhances the reliability of the mechanism.

[0055] Furthermore, when the two rotating explosion-proof panels 6 are closed, the two rotating explosion-proof panels 6 are rotated until they contact the corresponding spring plates 23 in the buffer assembly. At this time, the rotating explosion-proof panels 6 will drive the spring plates 23 to produce elastic deformation. The elastically deformed spring plates 23 can offset a part of the force transmitted to the rotating explosion-proof panels 6 by the tension springs 16 until the rotating rotating explosion-proof panels 6 contact the rubber buffer sleeves 22. At this time, the rubber buffer sleeves 22 can produce plastic deformation, thereby offsetting the remaining impact force when the rotating explosion-proof panels 6 are closed. This avoids the situation where the impact force is too large when the rotating explosion-proof panels 6 are closed, thereby reducing the service life of the equipment.

[0056] Furthermore, by setting the two rotating explosion-proof plates 6 in a scissor-like cross arrangement, the two rotating explosion-proof plates 6 can be closed like scissors when the explosion-proof valve body 1 is closed, and the cross-closing action can shear the gas to a certain extent. This closing method also has less resistance. Compared with the existing explosion-proof valve that uses a single plate to close, it has higher sensitivity and improved operating stability.

[0057] Working principle: When the monitoring head 24 detects that the gas concentration exceeds the standard, the temperature exceeds the standard, the pressure exceeds the standard, etc., the controller 3 will send a signal to the electric push rod 25. At this time, the output end of the electric push rod 25 will drive the sliding gear seat 18 to move backward in the slide rail frame 17. At this time, the small gear 19 on the sliding gear seat 18 can be disengaged from the large gear 13, and the large gear 13 separated from the small gear 19 will be rapidly rotated by the contraction force of the tension spring 16 on the control rod 10, thereby driving the control rod 10 and the large gear 13 to rotate a predetermined angle about the axis of the second fixed column 12, so that the rotating control rod 10 can drive the sliding column 8 to move at the same time through the second slide groove 14. When the sliding column 8 moves, it can drive the two rotating explosion-proof panels 6 to rotate relative to each other through the two sliders 9 thereon, so that the slider 9 can slide in the first slide groove 7, thereby driving the two rotating explosion-proof panels 6 to close quickly.

[0058] Furthermore, when it is necessary to open, the electric push rod 25 is started through the controller 3, and the electric push rod 25 drives the sliding gear seat 18 to move until the small gear 19 is engaged with the large gear 13. At this time, the worm gear self-locking motor 20 is started, and the output shaft of the worm gear self-locking motor 20 drives the large gear 13 and the control rod 10 thereon to rotate through the small gear 19, thereby stretching and deforming the tension spring 16, so that the rotating control rod 10 can open the two rotating explosion-proof panels 6.

[0059] Furthermore, when the two rotating explosion-proof panels 6 are closed, the two rotating explosion-proof panels 6 are rotated until they contact the corresponding spring plates 23 in the buffer assembly. At this time, the rotating explosion-proof panels 6 will drive the spring plates 23 to produce elastic deformation. The elastically deformed spring plates 23 can offset a part of the force transmitted to the rotating explosion-proof panels 6 by the tension springs 16 until the rotating rotating explosion-proof panels 6 contact the rubber buffer sleeves 22. At this time, the rubber buffer sleeves 22 can produce plastic deformation, thereby offsetting the remaining impact force when the rotating explosion-proof panels 6 are closed.

[0060] Furthermore, by setting the two rotating explosion-proof plates 6 in a scissor-like cross arrangement, the two rotating explosion-proof plates 6 can be closed like scissors when the explosion-proof valve body 1 is closed, and the cross-closing action can shear the gas to a certain extent. This closing method also has less resistance and has higher sensitivity than the existing explosion-proof valve that uses a single plate to close.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
