Description

Technical Field

[0001] The present invention relates to the field of mechanical technology, and in particular to a mechanical energy storage control system and a valve. Background Art

[0002] Valves are control components in pipeline fluid delivery systems that were created with the emergence of fluid pipelines. They are used to change the cross-section of the passage and the direction of medium flow, and have functions such as diversion, cutoff, throttling, check, diversion or overflow pressure relief. Valves used for fluid control are devices used to control the direction, pressure and flow of fluids. Valves are devices that make the medium (liquid, gas, powder) in piping and equipment flow or stop and can control its flow. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

[0003] At present, all valve production enterprises at home and abroad mainly have three types of valve control: manual, electric, and pneumatic. After an accident, combustion, or explosion, the power will be cut off; electric and pneumatic valves cannot be opened (closed), and combustion produces high temperature and toxic gases. Rescue personnel cannot get close to close (open) the valves. If the valves are not closed in time, it is very easy to cause a chain reaction and ignite the extremely toxic tanks nearby, which will be a large-scale ecological disaster. Rescue personnel risk their lives to enter the fire scene to manually close the valves, which seriously threatens the life safety of firefighters. For this reason, we have proposed a mechanical energy storage control system and valve to solve the above problems. Summary of the invention

[0014] Preferably, the valve body is a ball valve or a butterfly valve.

[0015] It can be seen from the above technical scheme that the present application provides a mechanical energy storage control system and valve. When in use, the power distribution control cabinet converts the 380V AC power in the factory into 220V DC power and 28V DC power. The 220V DC power is used to power the motor, and the 28V DC power is used to power the control unit. The power supply status, whether the second gear is rotating, the charging status of the battery unit and the battery unit power are displayed on the safety touch screen of the power distribution control cabinet for real-time monitoring. When the control unit cannot receive the 28V power input, the built-in wireless transmission module is turned on to obtain a remote wireless connection with the power distribution control cabinet and feedback is given to the mobile terminal. When the valve needs to be closed or opened, the control unit is remotely controlled to control the battery unit to release electric energy. The electromagnet is turned on through the electromagnetic relay built into the control unit to start the electromagnet pulling the separation pin. The second gear returns to its original position under the pulling force of the return spring to complete the opening or closing of the valve, thereby ensuring safe operation. Under normal use, when the valve needs to be opened or closed, The motor is started through an external circuit, and the motor drives the first rotating shaft to rotate, thereby driving the second rotating shaft to rotate through the first gear and the second gear. When the second rotating shaft rotates 90°, the valve opens to the maximum position. At this time, the valve core can still rotate, and the limit rod abuts on one side of the electromagnet's latch, and the limit rod rotates. When the second rotating shaft rotates again, the limit rod moves to the other side of the electromagnet's latch, and the first limit block touches the travel switch, the motor is turned off, and the second gear rotates in the opposite direction under the action of the return spring. When the valve core of the valve body returns to the 90° state, the limit rod abuts on the other side of the electromagnet's latch and one side of the fixed rod, and the bent end of the limit rod abuts on one side of the second limit block, thereby clamping the second gear in a state of rotating 90°, so that the valve body is opened or closed. When the valve body needs to be reset, the electromagnet's latch is controlled to shrink, and the limit rod is out of control. Under the action of the return spring, the second gear is reset, thereby resetting the valve body. During normal use, the external power supply charges the battery unit.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The opening and closing of the equipment is controlled by the cooperation of the return spring, travel switch, electromagnet and limit rod. The return spring is an energy storage structure. When there is no external energy input, the equipment is reset by energy storage. At the same time, it does not affect the normal use of the equipment and can accurately control the switch of the equipment.

[0018] 2. Through the cooperation of the battery unit, control unit and antenna, there is an internal power supply. When there is no external energy input to the device, the battery can be controlled to release power through the antenna and control unit, and the electromagnet can be started to pull the separation latch to complete the opening or closing of the device, ensuring safe operation;

[0019] 3. Through the cooperation of mechanical energy storage control system and valve, the opening and closing of valve is controlled. When the automatic valve has no external energy, it completes self-locking to ensure the safety of valve pipeline in emergency.

[0020] To sum up, when valves and other devices that open and close through torque are subjected to external forces, causing damage to external control pipelines, the present invention can remotely control the internal power supply to release electric energy, control the internal energy storage structure, close or open the equipment, and realize the switching of the equipment in an emergency, thereby ensuring safety in an emergency and avoiding the expansion of accidents, thereby protecting the personal and property safety of firefighters and enterprise personnel.

A first gear 6 is fixedly mounted on the first rotating shaft 5, and a second gear 10 is fixedly mounted on the second rotating shaft 8. The first gear 6 and the second gear 10 are meshed with each other. The radius of the first gear 6 is smaller than the radius of the second gear 10. The second gear 10 with a larger radius can reduce the tension of the return spring 3 and the force of rotating the first rotating shaft 5. A return spring 3 is rotatably connected to one side of the housing 1, and one end of the return spring 3 is rotatably connected to one side of the second gear 10. When the second gear 10 rotates, it is reset by the tension of the return spring 3. A first limit block 11 is fixed to one side of the second gear 10, and a travel switch 9 is fixed to the other side of the housing 1. The travel switch 9 and the first limit block 11 are fixed to one side of the housing 1. The limit switch 9 and the first limit block 11 correspond to each other, and the travel switch 9 and the first limit block 11 are arranged with the second gear 10 as the center at an angle greater than 90°. Since the limit rod 19 needs to be rotated more than 90° to rotate to the other side of the electromagnet 7 latch, when the limit rod 19 rotates to the other side of the electromagnet 7, the second gear 10 needs to rotate to realize that the limit rod 19 is stuck on the electromagnet 7. Therefore, the rotation angle of the second gear 10 needs to be greater than 90° to ensure that the second gear 10 rotates 90°, and the travel switch 9 is located on one side of the second gear 10, and a second limit block 20 is fixed on one side of the second gear 10, and a tension spring 17 is fixed on one side of the second limit block 20, and one end of the tension spring 17 is fixed to the limit rod 19, and both ends of the limit rod 19 are toward one side of the second limit block 20. The bending setting, the tension spring 17 is a straight line with fixed rods 18 on both sides, the two fixed rods 18 are fixed on the second gear 10, and the two fixed rods 18 are respectively located on both sides of the limit rod 19, wherein the fixed rod 18 closest to the center of the second gear 10 is located between the limit rod 19 and the second limit block 20, the limit rod 19 is limited by the fixed rod 18 and the second limit block 20, and the second gear 10 is controlled to be stuck after rotation, and an electromagnet 7 is fixed at the bottom of the shell 1, the electromagnet 7 and the limit rod 19 correspond, and the limit rod 19 and the electromagnet 7 are set at 90° with the second gear 10 as the center, and can be stuck when the second gear 10 rotates 90°. The battery unit 4, the control unit 12 and the antenna 16 are fixed in the shell 1.The control unit 12 is electrically connected to the battery unit 4, the electromagnet 7 and the antenna 16 respectively. The power distribution control cabinet 14 is equipped with a 220V DC line and a 28V DC line. The 220V DC line is connected to the control mechanism to control the normal operation of the equipment. The 28V DC line is connected to the control unit 12. 28V charges the battery unit to reduce the heat generated by the equipment inside the shell 1. The power distribution control cabinet 14 is equipped with a safety touch screen. The power supply status, whether the second gear 10 rotates, the charging status of the battery unit 4 and the battery unit 4 power are displayed on the safety touch screen of the power distribution control cabinet 14, which is convenient for real-time monitoring. A heat sink 13 is connected between the control unit 12 and the antenna 16. The heat sink 13 is a brass structure. When the external fire occurs and high temperature occurs, the heat transfer of the wire is reduced to protect the internal control unit.

[0034] In the present invention, the control unit 12 includes a power control module connected to 28V, located outside the shell 1, connected to an external power supply, surrounded by fireproof mud, a wireless transmission module connected to the antenna 16, for receiving external wireless signals, capable of transmitting via 4G, Bluetooth or 5G signals, a battery charging module connected to the battery unit 4 for charging, an electromagnetic relay module connected to the control electromagnet 7 and a processor for processing the relationship between each line, controlling the normal operation of each line, and charging when the battery unit 4 is less than 50%, to ensure that the internal energy storage can operate normally.

[0035] In the present invention, the control mechanism includes a motor installed at the upper end of the housing 1, one end of the first rotating shaft 5 is fixed to the end of the output shaft of the motor, and the motor controls the first rotating shaft 5 to realize the opening or closing of the device. The motor is controlled by a 220V circuit.

[0036] In the present invention, the limiting mechanism includes a mounting block 23 fixed to the bottom of the housing 1, a sleeve 25 is fixed to one side of the mounting block 23, a buffer spring 26 is arranged in the sleeve 25, a movable plate 28 is arranged in the sleeve 25, the movable plate 28 abuts against one end of the buffer spring 26, a buffer rod 24 is fixed to one side of the movable plate 28, a through hole is arranged on one side of the mounting block 23, one end of the buffer rod 24 passes through the through hole and extends to the other side of the mounting block 23, the buffer rod 24 corresponds to the baffle 22, and when the second rotating shaft 8 is reset, the baffle 22 abuts against the buffer rod 24, The second rotating shaft 8 is limited by compressing the buffer spring 26 for buffering.

A threaded through hole is provided at the bottom of the sleeve 25, and an adjusting screw 27 is provided at the bottom of the sleeve 25. The adjusting screw 27 passes through the threaded through hole and extends to one end of the sleeve 25. By adjusting the length of the adjusting screw 27 in the sleeve 25, the buffer spring 26 is compressed, and the elastic force of the buffer rod 24 is adjusted, thereby adjusting the resistance to over-rotation after the baffle 22 is reset.

[0037] See also Fig. 9 A valve includes a valve body 21, which is connected to a mechanical energy storage control system. One end of a second rotating shaft 8 in the mechanical energy storage control system is connected to a valve core of the valve body 21 to control the opening and closing of the valve body 21. The valve body 21 is a ball valve or a butterfly valve. A small rotation angle facilitates the opening and closing of the structure. When a valve with a large rotation angle is encountered, a large angle rotation can be achieved through an external gear. When the valve body 21 is subjected to external force and the external control pipeline is damaged, the internal power supply is remotely controlled to release electrical energy, control the internal energy storage structure, close or open the valve body 21, and realize the opening and closing of the valve in an emergency, thereby ensuring the pipeline safety in an emergency and avoiding the expansion of accidents, thereby protecting the personal and property safety of firefighters and enterprise personnel.

[0038] It can be seen from the above technical solution that when in use, the power distribution control cabinet 14 converts the 380V AC power in the factory into 220V DC power and 28V DC power. The 220V DC power is used to power the motor, and the 28V DC power is used to power the control unit 12. The power supply status, whether the second gear 10 is rotating, the charging status of the battery unit 4 and the power of the battery unit 4 are displayed on the safety touch screen of the power distribution control cabinet 14 for real-time monitoring. When the control unit 12 cannot receive the 28V power input, the built-in wireless transmission module is turned on to obtain a remote wireless connection with the power distribution control cabinet 14 and feedback is given to the mobile terminal. When the valve needs to be closed or opened, the control unit 12 is remotely controlled to control the battery unit 4 to release electric energy. The electromagnetic relay built into the control unit 12 turns on the electromagnet 7, and the electromagnet 7 is started to pull the separation latch. The second gear 10 returns under the pulling force of the return spring 3 to complete the opening or closing of the valve to ensure safe operation. Under normal use, when the valve needs to be opened or closed, the motor is started through the external circuit, and the motor drives the first rotating shaft 5 to rotate. The second gear 10 drives the second shaft 8 to rotate through the first gear 6 and the second gear 10. When the second shaft 8 rotates 90°, the valve opens to the maximum position. At this time, the valve core can still rotate, and the limit rod 19 abuts against one side of the latch of the electromagnet 7. The limit rod 19 rotates. When the second shaft 8 rotates again, the limit rod 19 moves to the other side of the latch of the electromagnet 7. The first limit block 11 touches the travel switch 9, the motor is turned off, and the second gear 10 rotates in the opposite direction under the action of the return spring 3. When the valve core of the valve body 21 returns to the 90° position, the valve core of the valve body 21 is turned back to the 90° position. In the open state, the limit rod 19 abuts against the other side of the pin of the electromagnet 7 and one side of the fixing rod 18, and the bent end of the limit rod 19 abuts against one side of the second limit block 20, thereby locking the second gear 10 in a state of rotation of 90°, so that the valve body 21 is opened or closed. When the valve body 21 needs to be reset, the pin of the control electromagnet 7 is contracted, and the limit rod 19 is out of control. Under the action of the return spring 3, the second gear 10 is reset, thereby resetting the valve body 21. During normal use, the external power supply charges the battery unit 4.
