Description

Technical Field

[0001] The invention relates to the technical field of pressure temperature measurement and signal transmission, and in particular to a solar-powered explosion-proof remote pressure and temperature transmitter. Background Art

[0002] In industrial production, such as petrochemical, natural gas mining and transportation, and many flammable and explosive places in coal mines, accurate measurement and remote transmission of pressure and temperature are crucial. At present, remote pressure and temperature transmitters are installed on the basis of pipelines. However, traditional remote pressure and temperature transmitters still have the following shortcomings when used:

[0003] First, the transmitter has installation stability defects. Traditional transmitters are prone to vibration in complex industrial environments and under human factors. When anti-loosening gaskets are used, the anti-loosening gaskets have an elastic life, which causes the installation position of the transmitter to loosen, posing a safety hazard of gas leakage.

[0004] Secondly, the transmitter has protection and safety defects. The display screen of the previous transmitter is directly exposed to the air, which is easy to be damaged by external dust, debris, water vapor and accidental collision, thus shortening the service life of the transmitter. When the internal part of the transmitter sparks, it is easy to cause a serious safety accident such as the transmitter explosion.

[0005] In addition, traditional pressure and temperature transmitters usually rely on AC or battery power. In some remote or power-inconvenient areas, AC power access is expensive and difficult, while battery power needs to be replaced regularly, has high maintenance costs and may cause measurement interruptions due to battery exhaustion.

[0021] The design of the alarm component provides a solid backing for the safe operation of the equipment. When the equipment encounters an abnormal situation, the alarm can promptly send out an alarm signal to remind the staff to pay attention to the equipment status. Once a fire hazard occurs, the alarm of the alarm causes the electromagnet to be powered off. Under the action of the spring, the ejector quickly moves downward to pierce the fire extinguishing ball, and the fire extinguishing powder is instantly sprayed into the main body of the transmitter to extinguish the fire, effectively preventing serious safety accidents caused by ignition and explosion of the equipment, ensuring the safety of personnel lives and the integrity of industrial production facilities, and avoiding huge economic losses and production interruptions caused by fire accidents.

[0022] The equipped solar panel uses clean energy solar energy to provide power support for the transmitter body and alarm components. There is no need to rely on traditional mains electricity or frequent battery replacement, which reduces the consumption of non-renewable energy and reduces energy costs. Especially in some remote areas or industrial sites with inconvenient power supply, solar power supply enables it to operate independently and stably without being restricted by mains power supply, which broadens the application range of the equipment.

[0052] In the embodiments of the present disclosure, reference Figures 1 to 9 As shown,

[0053] A set of alarm components 8 are installed at the outer position of the stable sleeve 102. The alarm component 8 is composed of a stable shell 801, a warning device 802, a fire extinguishing ball 803, an adapter 804, an electromagnet 805 and a ejector pin 806. A warning device 802 is installed at the inner position of the stable shell 801. The warning device 802 is composed of a warning light and a control panel. An adapter 804 is welded at the bottom of the warning device 802. A conductive groove is opened on one side of the adapter 804. One side of the conductive block 103 extends to the inside of the conductive groove. At this time, the conductive block 103, the adapter 804 and the alarm device 802 are automatically electrically connected, which solves the problem that the alarm component 8 needs to be equipped with a separate connector. As well as the wiring problem, a stabilizing cover is provided on one side of the adapter 804, an electromagnet 805 is installed inside the stabilizing cover, the electromagnet 805 and the adapter 804 are electrically connected, and a control module of the prior art needs to be set up, when the alarm 802 sounds an alarm, the electromagnet 805 is powered off, a group of stabilizing frames are provided inside the stabilizing shell 801, a sliding hole is opened in the middle position of the stabilizing frame, a ejector pin 806 is installed at the position of the sliding hole, the stabilizing frame positions the ejector pin 806 laterally and circumferentially, so that the ejector pin 806 can stably move up and down at the position of the sliding hole, the material of the ejector pin 806 is selected from the iron material of the prior art, and the electromagnet 805 is powered on After that, it can effectively absorb the ejector pin 806 and move it upward. A fire extinguishing ball 803 is installed at the bottom of the inner side of the stable shell 801. A sealing cover is installed at the bottom of the stable shell 801. The sealing cover seals and limits the bottom of the stable shell 801. The setting of the sealing cover is convenient for the replacement of the fire extinguishing ball 803. The fire extinguishing ball 803 adopts the commonly used structure for fire extinguishing in the prior art. A supporting spring is installed at the outer side of the ejector pin 806. When the electromagnet 805 is powered off, the ejector pin 806 moves downward quickly under the support of the spring to puncture the fire extinguishing ball 803. At this time, the fire extinguishing ball 803 explodes and sprays the fire extinguishing powder. The fire extinguishing powder passes through the interior of the stable sleeve 102 and enters The fire is extinguished inside the transmitter body 1, which effectively solves the problem of ignition and explosion of the transmitter body 1. The control panel of the alarm 802 integrates multiple sensors such as temperature sensor, current sensor, voltage sensor, etc., which monitor the operating parameters inside the transmitter body 1 in real time. When the sensor detects an abnormal signal, such as temperature exceeding 120°C (which can be set according to actual needs), current overcurrent or voltage overvoltage, the signal is transmitted to the microprocessor. After analysis and processing by the microprocessor, on the one hand, the warning light is turned on, and on the other hand, the alarm signal is sent to the programmable logic controller (PLC) control module to cut off the power supply of the electromagnet 805 and trigger the fire extinguishing mechanism.

[0054] The control module used in the present invention is a programmable logic controller (PLC), such as Siemens S7-200SMART series PLC. The PLC control module is connected to the alarm device 802 through an input interface to receive the alarm signal sent by it, and is connected to the electromagnet 805 through an output interface to control the power on and off of the electromagnet 805. When the alarm device 802 detects an abnormality inside the transmitter body 1 and sends an alarm signal, the PLC control module cuts off the power supply of the electromagnet 805 according to a preset logic program, triggering a fire extinguishing mechanism.

[0055] The stabilizing sleeve 102 surrounds the outer side of the transmitter body 1, and there is a gap between the two. Channels communicating with the inside of the transmitter body 1 are provided at the bottom and top of the stabilizing sleeve 102. When the ejector pin 806 pierces the fire extinguishing ball 803, the fire extinguishing powder enters the gap between the two through the channel at the bottom of the stabilizing sleeve 102 under the action of the pressure inside the ball and gravity, and then enters the inside of the transmitter body 1 through the top channel to achieve fire extinguishing.

[0056] The reserve of fire extinguishing powder is determined according to the size of the internal space of the transmitter body 1 and the fire protection standard. After calculation, the internal space volume of the transmitter body 1 of the present invention is 0.1 cubic meter. According to the spray intensity standard of dry powder fire extinguishing agent for electrical equipment fire, 0.5-1.5 kilograms per cubic meter is required. Considering the safety margin, the reserve of fire extinguishing powder is finally determined to be 0.1 kilogram to ensure that fires of different severity can be effectively extinguished.

[0057] In the embodiments of the present disclosure, reference Figures 1 to 9 As shown,

[0058] A set of limiting structures 9 are installed at the upper position of the transmitter body 1. The limiting structure 9 is composed of a positioning shell 901 and a limiting rod 902. A set of mounting holes are respectively provided on both sides of the positioning shell 901, and the mounting holes are used to install fixing bolts. The positioning shell 901 is installed at the upper position of the transmitter body 1. A sliding hole is provided in the middle position of the positioning shell 901. A sliding groove is provided at the upper position on the basis of the sliding hole. The limiting rod 902 passes through the inside of the sliding hole. A control panel is provided on the outer side of the limiting rod 902. The control panel passes through the inside of the sliding groove. After the staff applies a pressure on the control panel, the limiting rod 902 can be pushed in the opposite direction. At this time, the alarm component 8 can be unlocked for removal. A positioning groove aligned with the limiting rod 902 is provided on one side of the upper position of the stable shell 801. A supporting spring is installed at the outer position of the limiting rod 902. The supporting spring pushes one side of the limiting rod 902 to move to the inside of the positioning groove of the stable shell 801. The limiting rod 902 can achieve the effect of rapid positioning of the stable shell 801, thereby avoiding the displacement of the alarm component 8 after installation.

[0059] Embodiment 2, based on embodiment 1, refers to Figures 1 to 9As shown, the solar panel 3 is electrically connected to the wiring block of the conductive block 103 with reference to the wiring structure of the prior art through a power cord, and the solar panel 3 is also electrically connected to the control board of the transmitter main body 1 with reference to the wiring structure of the prior art through a power cord. The solar panel 3 supplies power to the transmitter main body 1 and the alarm component 8.

[0060] The working principle of this embodiment:

[0061] Steps for preparation before installation: The staff checks whether the transmitter main body 1 and its components are intact, ensuring that key components such as the positioning block 101, the stabilizing sleeve 102, and the conductive block 103 are not deformed, damaged, or attached with foreign objects. Check whether the positioning frame 201 and the protective cover 202 of the protective structure 2 can be opened and closed normally and whether the hinge connection is stable; check whether the surface of the solar panel 3 is clean and without damage and whether the wiring is normal. Confirm that components such as the warning device 802, the fire extinguishing ball 803, the adapter 804, the electromagnet 805, and the ejector pin 806 in the alarm component 8 are firmly installed, all connection parts are tight, and the spring has normal elasticity; check whether the positioning housing 901 and the limiting rod 902 of the limiting structure 9 can be operated flexibly and whether the supporting spring works normally.

[0062] Steps for installing the transmitter main body 1: The staff aligns the positioning block 101 at the bottom of the transmitter main body 1 with the corresponding structure at the installation position, passes the locking bolt 5 through the sliding hole of the positioning block 101, and rotates the locking bolt 5 to preliminarily fix the transmitter main body 1. Then, push the control board of the anti-loosening block 4 so that the locking block of the anti-loosening block 4 engages with the card slot at the large head of the locking bolt 5 to achieve the anti-loosening effect and further stabilize the installation position of the transmitter main body 1. Align the anti-loosening nut 6 with the docking sleeve above the pipeline 7, and use the elasticity of the elastic member 601 to support, so that the locking block of the anti-loosening nut 6 engages with the card slot of the docking sleeve to complete the connection and locking of the transmitter main body 1 and the pipeline 7 and prevent gas leakage.

[0063] Steps for installing and debugging the protective structure 2: The staff installs the positioning frame 201 on the outside of the stabilizing sleeve 102 through the U-shaped installation grooves on both sides. After installation, tighten the locking nut on the outside of the stabilizing sleeve 102 to ensure that the installation position of the positioning frame 201 is stable. Check whether the protective cover 202 can be normally flipped under the action of the hinge. When the transmitter main body 1 does not need to be operated, the protective cover 202 should naturally droop under its own weight to protect the display screen of the transmitter main body 1. The protective cover 202 is convenient for operating the transmitter main body 1 after flipping.

[0064] The alarm component 8 and the limiting structure 9 are set up in steps. The staff installs the stable housing 801 of the alarm component 8 on the outside of the stable sleeve 102, and allows the limiting rod 902 to pass through the sliding hole of the positioning housing 901. Under the action of the supporting spring, one side of the limiting rod 902 is moved to the inside of the positioning groove of the stable housing 801, so as to realize the rapid positioning and locking of the stable housing 801 and prevent its displacement. The staff checks whether the connection between the alarm 802 and the adapter 804 is normal, and ensures that one side of the conductive block 103 extends to the inside of the conductive groove of the adapter 804 to realize automatic electrical connection.

[0065] The connection and power supply test steps of the solar panel 3 are as follows: the staff electrically connects the power line of the solar panel 3 to the wiring block of the conductive block 103 and the control panel of the transmitter body 1 according to the wiring structure of the prior art, and tests whether the solar panel 3 can normally provide power to the transmitter body 1 and the alarm component 8 under light conditions, and checks whether each component can work normally, such as whether the alarm 802 can display normally, and whether the electromagnet 805 can be normally energized to adsorb the ejector pin 806;

[0066] The electromagnet 805 and the adapter 804 are electrically connected, and a control module of the prior art needs to be set. When the alarm 802 sounds, the electromagnet 805 is powered off, and the stabilizing frame positions the ejector pin 806 laterally and circumferentially, so that the ejector pin 806 can stably move up and down at the position of the sliding hole. The material of the ejector pin 806 is the iron material of the prior art. After the electromagnet 805 is powered on, it can effectively absorb the ejector pin 806 and move it upward. When the electromagnet 805 is powered off, the ejector pin 806 moves downward quickly under the support of the spring to pierce the fire extinguishing ball 803. The fire extinguishing ball 803 explodes and sprays the fire extinguishing powder. The fire extinguishing powder passes through the interior of the stabilizing sleeve 102 and enters the interior of the transmitter body 1 to extinguish the fire. The reserve of the fire extinguishing powder is determined according to the size of the internal space of the transmitter body 1 and the fire protection standard. After calculation, the volume of the internal space of the transmitter body 1 of the present invention is 0.1 cubic meter. According to the spray intensity standard of the dry powder fire extinguishing agent for electrical equipment fire, 0.5-1.5 kilograms per cubic meter are required. Considering the safety margin, the reserve of the fire extinguishing powder is finally determined to be 0.1 kilogram to ensure that fires of different severity can be effectively extinguished.

[0067] Daily use and maintenance steps: The staff regularly checks the accuracy of the measurement data of the transmitter body 1, calibrates it in time if there is any deviation, checks whether the protective cover 202 is properly protected, repairs or replaces it in time if it is damaged, and regularly checks the components in the alarm component 8, such as checking whether the fire extinguishing ball 803 is within the validity period, whether the sealing cover is well sealed, and whether the alarm 802 is working properly;

[0068] If it is necessary to remove the transmitter body 1 and the alarm component 8, for the transmitter body 1, push the anti-loosening nut 6 upward to separate the locking block from the slot, then rotate the locking bolt 5 and push the control panel of the anti-loosening block 4 to unlock it, and then it can be removed; for the alarm component 8, press the control panel of the limit rod 902 to withdraw the limit rod 902 from the positioning groove of the stable shell 801, and then the removal operation can be carried out.
