Description

Technical Field

[0001] This invention relates to the field of thermal power plants, and in particular to a positioning device and method for safe production in thermal power plants. Background Technology

[0002] A thermal power plant, or coal-fired power plant for short, is a factory that uses combustible materials (such as coal) as fuel to produce electricity. Its basic production process is as follows: when the fuel is burned, it heats water to generate steam, which converts the chemical energy of the fuel into heat energy. The steam pressure drives the turbine to rotate, converting the heat energy into mechanical energy. Then the turbine drives the generator to rotate, converting the mechanical energy into electrical energy.

[0003] Traditional thermal power plants employ IoT-based smart positioning systems to ensure employee safety during production. These systems connect to Bluetooth positioning tags via a control terminal to pinpoint the employee's real-time location within the plant. However, these tags are typically worn around the employee's neck with a lanyard. When employees run, the tags swing back and forth, increasing friction at the connection point and potentially causing the lanyard to break. This results in the tag detaching from the plant, and if the employee doesn't notice the tag is missing, real-time location tracking becomes impossible, jeopardizing their safety. To address these issues, we propose a positioning device for safe production in thermal power plants. Summary of the Invention

[0012] Preferably, a reset spring is fixedly connected to the center of the top of the back of the Bluetooth positioning work badge, and the back of the reset spring is fixedly connected to the center of the top of the front of the fixing plate.

[0013] Preferably, a first clamping plate is fixedly connected to the middle of the bottom back of the Bluetooth positioning work badge, and a second clamping plate is fixedly connected to the middle of the bottom front of the fixed clamping plate. The second clamping plate and the first clamping plate are respectively provided with toothed grooves at their opposite ends, and the two sets of toothed grooves mesh with each other.

[0014] Preferably, the bottom end of the external block is provided with a guide cavity for the positioning block to slide, and both sides of the guide cavity are provided with a limiting groove for the limiting slide rod to slide, and one side of the limiting groove is provided with a guide groove for the guide slide rod to slide.

[0015] Preferably, the back of the external block is provided with a vertical groove that communicates with the guide slide cavity. An auxiliary slider is slidably sleeved inside the vertical groove. The front of the auxiliary slider is fixedly connected to the back of the positioning block. An auxiliary plate is fixedly connected to the back of the auxiliary slider. Multiple protrusions are fixedly connected to the back of the auxiliary plate.

[0016] Preferably, a fastening spring is fixedly connected to the top end of the limiting slide rod, and the top end of the fastening spring is fixedly connected to the inner wall of the top end of the limiting slide groove.

[0017] Preferably, one end of the limiting slide rod is provided with a guide groove for sliding the locking rod, and a limiting groove for sliding the limiting slide is provided on one side of the guide groove. The limiting slide is fixedly connected to the end opposite to the locking rod, the positioning spring is fixedly connected to one end of the limiting slide, and one end of the positioning spring is fixedly connected to the inner wall of one side of the limiting groove.

[0018] Preferably, the outer block has two sets of transverse grooves that are connected to the guide slide grooves. Guide sliders are slidably fitted inside the transverse grooves. The opposite ends of the two guide sliders are fixedly connected to the two sides of the guide slide rod, and a guide spring is fixedly connected to the inner wall of one side of the transverse groove. One end of the guide spring is fixedly connected to one end of the guide slider.

[0019] A method for using a positioning device for safe production in thermal power plants, the method comprising the following steps:

[0020] Step 1: First, hold the Bluetooth positioning work tag in your hand, then hold the auxiliary plate with your fingers, and then move the auxiliary plate towards the top of the Bluetooth positioning work tag. The auxiliary plate drives the positioning block to move through the auxiliary slider. The positioning block compresses the fastening spring through the limit slide rod, causing it to contract and store force.

[0021] As the limiting slide rod moves, it drives the guide groove to move. When the guide groove is aligned with the end of the transverse groove, the positioning spring releases its elastic force and pushes the limiting slide plate to slide along the inside of the limiting groove. The limiting slide plate pushes the locking rod to slide along the inside of the guide groove until one end of the locking rod is locked into the inside of the transverse groove and stops. At this time, the force on the auxiliary plate is released.

[0022] Step 2: Next, press the top of the fixing plate towards the top of the back of the Bluetooth positioning work tag. When the fixing plate rotates, the linkage torsion spring is deformed and stores force.

[0023] At the same time, the fixed clamping plate compresses the reset spring to make it contract and store force, while the other end of the fixed clamping plate drives the second clamping plate to disengage from the first clamping plate;

[0024] Step 3: Next, engage the first clamping plate and the second clamping plate on the folded edge of the worker's clothes. Then, release the pressure on the fixed clamping plate. At this time, the linkage torsion spring releases torque, and the return spring releases elasticity to push the fixed clamping plate to move. This causes one end of the fixed clamping plate to move the second clamping plate closer to the first clamping plate, thereby clamping the second clamping plate and the first clamping plate on both sides of the folded edge of the clothes.

[0025] Step 4: Next, squeeze the guide slide rods on both sides of the outer block. The guide slide rods squeeze the snap-fit ​​rod. When the snap-fit ​​rod moves out of the inside of the guide slide groove, the fastening spring releases its elasticity and pushes the limit slide rod to slide along the inside of the limit slide groove. The limit slide rod drives the positioning block to slide along the inside of the guide slide cavity, so that the bottom of the positioning block is inserted between the Bluetooth positioning work card and the fixing clamp.

[0026] Next, release the pressure on the guide slide rod, at which point the guide slide rod will reset under the action of the guide spring.

[0027] The technical effects and advantages of this invention are as follows:

[0028] (1) The present invention utilizes the design of the clamping and fixing component, and through the elastic force of the reset spring and the torque of the linkage torsion spring, ensures that the second clamping plate and the first clamping plate are stably clamped on both sides of the folded edge of the clothing. Through the interlocking of the teeth, the clamping stability is improved, the installation stability is ensured, and the phenomenon of the Bluetooth positioning work tag detaching from the folded edge of the clothing under the impact of external force is prevented.

[0029] (2) The present invention utilizes the design of the locking component, which is composed of an external block and a positioning block. The two sides of the bottom end of the positioning block are both convex arc surfaces, which facilitates the movement of the positioning block along the Bluetooth positioning work tag. The positioning block can prevent the fixed clamp from rotating due to external pressure after the Bluetooth positioning work tag is installed. This allows the first clamping plate and the second clamping plate to be stably engaged on both sides of the garment fold, avoiding the phenomenon of the Bluetooth positioning work tag detaching from the garment fold under the impact of external force.

[0030] (3) The present invention can form a mechanical linkage through the cooperation of the snap-fit ​​mechanism and the auxiliary mechanism. When it is necessary to move the fixed clamping plate, the positioning block is first moved into the interior of the guide slide cavity. The positioning block drives the limiting slide rod to squeeze the fastening spring to contract and store force. When the limiting slide rod drives the snap-fit ​​rod to the end of the guide slide groove, the snap-fit ​​rod is snapped into the interior of the guide slide groove under the elastic force of the positioning spring. At this time, the fixed clamping plate can move. When it is necessary to fix the fixed clamping plate, the guide slide rod is squeezed to make the guide spring squeeze and store force. The guide slide rod squeezes the snap-fit ​​rod out of the interior of the guide slide groove. Under the elastic force of the fastening spring, the positioning block is moved out of the interior of the guide slide cavity and placed between the Bluetooth positioning work card and the fixed clamping plate. At this time, the fixed clamping plate can be fixed. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] This invention provides, for example Figure 1-6 The positioning device shown includes a Bluetooth positioning work badge 1, a clamping and fixing component, and a locking component.

[0040] The front of the Bluetooth positioning work badge 1 is equipped with an electronic display screen 14;

[0041] The clamping and fixing assembly is located in the middle of the back of the Bluetooth positioning work badge 1. The clamping and fixing assembly includes a fixing plate 2, two sets of hinge seats 11, a hinge rod 1101, and a linkage torsion spring 1102. The two ends of the hinge rod 1101 are respectively fixedly inserted into the interior of the two inner hinge seats 11, and the two ends of the hinge rod 1101 are respectively rotatably inserted into the interior of the two outer hinge seats 11. One end of the two hinge seats 11 is fixedly connected to the top of the back of the Bluetooth positioning work badge 1, and one end of the other two hinge seats 11 is fixedly connected to the top of the front of the fixing plate 2. The linkage torsion spring 1102 is rotatably sleeved on the outside of the hinge rod 1101. One end of the linkage torsion spring 1102 is fixedly connected to the back of the Bluetooth positioning work badge 1, and the other end of the linkage torsion spring 1102 is fixedly connected to the front of the fixing plate 2.

[0042] A reset spring 13 is fixedly connected to the middle of the top of the back of the Bluetooth positioning work badge 1. The back of the reset spring 13 is fixedly connected to the middle of the top of the front of the fixed clamping plate 2. The reset spring 13 is initially in a state of compression and storage. The elastic force of the reset spring 13 can reset the top of the fixed clamping plate 2, thereby making the first clamping plate 12 and the second clamping plate 21 stably attached together.

[0043] A first clamping plate 12 is fixedly connected to the middle of the bottom back of the Bluetooth positioning work badge 1, and a second clamping plate 21 is fixedly connected to the middle of the bottom front of the fixed clamping plate 2. The second clamping plate 21 and the first clamping plate 12 are respectively provided with toothed grooves at their opposite ends, and the two sets of toothed grooves mesh with each other.

[0044] By using the elastic force of the return spring 13 and the torque of the linkage torsion spring 1102, the second clamping plate 21 and the first clamping plate 12 are stably clamped on both sides of the folded edge of the garment. The interlocking of the teeth improves the clamping stability, ensures the stability of the installation, and prevents the Bluetooth positioning work tag 1 from detaching from the folded edge of the garment under the impact of external forces.

[0045] The locking component is located on the top of the back of the Bluetooth positioning work card 1. The locking component includes an external block 3 and a positioning block 31. The positioning block 31 is slidably inserted into the interior of the bottom end of the external block 3. The bottom of the positioning block 31 is located between the Bluetooth positioning work card 1 and the fixing plate 2.

[0046] A fastening spring 33 is fixedly connected to the top of the limiting slide bar 32. The top of the fastening spring 33 is fixedly connected to the inner wall of the top of the limiting slide groove. The fastening spring 33 is initially in a state of compression and storage. The elastic force of the fastening spring 33 can make the positioning block 31 stably placed between the Bluetooth positioning work card 1 and the fixed clamp 2.

[0047] The two sides of the bottom end of the positioning block 31 are both convex arc surfaces, which facilitates the movement of the positioning block 31 along the Bluetooth positioning work tag 1. The positioning block 31 can prevent the fixed clamp plate 2 from being rotated due to external pressure after the Bluetooth positioning work tag 1 is installed. This ensures that the first clamping plate 12 and the second clamping plate 21 are stably engaged on both sides of the garment fold, preventing the Bluetooth positioning work tag 1 from detaching from the garment fold under external impact.

[0048] The bottom end of the outer block 3 is provided with a guide cavity for the positioning block 31 to slide. Both sides of the guide cavity are provided with a limiting groove for the limiting slide rod 32 to slide. One side of the limiting groove is provided with a guide groove for the guide slide rod 34 to slide.

[0049] The back of the outer block 3 is provided with a vertical groove that communicates with the guide slide cavity. An auxiliary slider 35 is slidably sleeved inside the vertical groove. The front of the auxiliary slider 35 is fixedly connected to the back of the positioning block 31. An auxiliary plate 3501 is fixedly connected to the back of the auxiliary slider 35. Multiple protrusions are fixedly connected to the back of the auxiliary plate 3501. The positioning block 31 can be easily moved by the cooperation between the auxiliary plate 3501 and the auxiliary slider 35.

[0050] Both sides of the positioning block 31 are fixedly connected to the limiting slide rod 32. The limiting slide rod 32 is provided with a locking mechanism. The locking mechanism includes a locking rod 3203, a limiting slide plate 3202 and a positioning spring 3201. One end of the limiting slide rod 32 is provided with a guide groove for the locking rod 3203 to slide. One side of the guide groove is provided with a limiting groove for the limiting slide plate 3202 to slide. The end of the limiting slide plate 3202 opposite to the locking rod 3203 is fixedly connected. The positioning spring 3201 is fixedly connected to one end of the limiting slide plate 3202. One end of the positioning spring 3201 is fixedly connected to the inner wall of one side of the limiting groove.

[0051] Auxiliary mechanisms are provided on both sides inside the outer block 3, and the auxiliary mechanisms include guide slide rods 34;

[0052] The outer block 3 has two sets of transverse grooves that are connected to the guide slide groove. The guide slider 3401 is slidably sleeved inside the transverse groove. The opposite ends of the two guide sliders 3401 are fixedly connected to the two sides of the guide slide rod 34. A guide spring 3402 is fixedly connected to the inner wall of one side of the transverse groove. One end of the guide spring 3402 is fixedly connected to one end of the guide slider 3401.

[0053] The interlocking mechanism and the auxiliary mechanism work together to form a mechanical linkage. When it is necessary to move the fixed clamp 2, the positioning block 31 is first moved into the guide cavity. The positioning block 31 drives the limiting slide rod 32 to compress the fastening spring 33, causing it to contract and store force. When the limiting slide rod 32 drives the locking rod 3203 to move to the end of the guide groove, the locking rod 3203 is locked into the guide groove under the elastic force of the positioning spring 3201. At this time, the fixed clamp 2 can move. When it is necessary to fix the fixed clamp 2, the guide slide rod 34 is compressed, causing the guide spring 3402 to be compressed and stored. The guide slide rod 34 pushes the locking rod 3203 out of the guide groove. Under the elastic force of the fastening spring 33, the positioning block 31 is moved out of the guide cavity and placed between the Bluetooth positioning work card 1 and the fixed clamp 2. At this time, the fixed clamp 2 can be fixed.

[0054] A method for using a positioning device for safe production in thermal power plants, comprising the following steps:

[0055] Step 1: First, hold the Bluetooth positioning work tag 1 in your hand, then hold the auxiliary plate 3501 with your fingers, and then move the auxiliary plate 3501 towards the top of the Bluetooth positioning work tag 1. The auxiliary plate 3501 drives the positioning block 31 to move through the auxiliary slider 35. The positioning block 31 compresses the fastening spring 33 through the limiting slide bar 32, causing it to contract and store force.

[0056] As the limiting slide bar 32 moves, it drives the guide groove to move. When the guide groove is aligned with the end of the transverse groove, the positioning spring 3201 releases its elastic force to push the limiting slide plate 3202 to slide along the inside of the limiting groove. The limiting slide plate 3202 pushes the locking rod 3203 to slide along the inside of the guide groove until one end of the locking rod 3203 is locked into the inside of the transverse groove and stops. At this time, the force on the auxiliary plate 3501 is released.

[0057] Step 2: Next, press the top of the fixing plate 2 towards the top of the back of the Bluetooth positioning work tag 1. When the fixing plate 2 rotates, the linkage torsion spring 1102 is deformed and stores force.

[0058] At the same time, the fixed clamping plate 2 compresses the reset spring 13 to make it contract and store force, and at the same time, the other end of the fixed clamping plate 2 drives the second clamping plate 21 to disengage from the first clamping plate 12.

[0059] Step 3: Next, engage the first clamping plate 12 and the second clamping plate 21 on the folded edge of the worker's clothes. Then, release the pressure on the fixed clamping plate 2. At this time, the linkage torsion spring 1102 releases torque, and the return spring 13 releases elasticity to push the fixed clamping plate 2 to move. This causes one end of the fixed clamping plate 2 to move the second clamping plate 21 closer to the first clamping plate 12, thereby clamping the second clamping plate 21 and the first clamping plate 12 on both sides of the folded edge of the clothes.

[0060] Step 4: Next, press the guide slide rods 34 on both sides of the outer block 3. The guide slide rods 34 press the snap-fit ​​rod 3203. When the snap-fit ​​rod 3203 moves out of the inside of the guide slide groove, the fastening spring 33 releases its elastic force and pushes the limiting slide rod 32 to slide along the inside of the limiting slide groove. The limiting slide rod 32 drives the positioning block 31 to slide along the inside of the guide slide cavity, so that the bottom of the positioning block 31 is inserted between the Bluetooth positioning work card 1 and the fixing clamp 2.

[0061] Next, the pressure on the guide slide bar 34 is released, and the guide slide bar 34 is reset under the action of the guide spring 3402.

[0062] Working principle of this invention: The method of using the positioning device for safe production in thermal power plants includes the following steps:

[0063] Step 1: First, hold the Bluetooth positioning work tag 1 in your hand, then hold the auxiliary plate 3501 with your fingers, and then move the auxiliary plate 3501 towards the top of the Bluetooth positioning work tag 1. The auxiliary plate 3501 drives the auxiliary slider 35 to slide along the inside of the vertical groove. The auxiliary slider 35 drives the positioning block 31 to slide along the inside of the guide slide cavity. The positioning block 31 drives the limiting slide rod 32 to slide along the inside of the limiting slide groove. While the limiting slide rod 32 moves, it squeezes the fastening spring 33, causing it to contract and store force.

[0064] As the limiting slide bar 32 moves, it drives the guide groove to move. When the guide groove is aligned with the end of the transverse groove, the positioning spring 3201 releases its elastic force to push the limiting slide plate 3202 to slide along the inside of the limiting groove. The limiting slide plate 3202 pushes the locking rod 3203 to slide along the inside of the guide groove until one end of the locking rod 3203 is locked into the inside of the transverse groove and stops. At this time, the force on the auxiliary plate 3501 is released.

[0065] Step 2: Next, press the top of the fixing plate 2 towards the top of the back of the Bluetooth positioning work tag 1, so that the fixing plate 2 drives the hinge rod 1101 to rotate along the inside of the hinge seat 11 on the back of the Bluetooth positioning work tag 1 through the hinge seat 11 on its front side. Since the two ends of the external linkage torsion spring 1102 of the hinge rod 1101 are fixedly connected to the back of the Bluetooth positioning work tag 1 and the front of the fixing plate 2 respectively, the linkage torsion spring 1102 is deformed and stores force when the fixing plate 2 rotates.

[0066] At the same time, the fixed clamping plate 2 compresses the reset spring 13 to make it contract and store force, and at the same time, the other end of the fixed clamping plate 2 drives the second clamping plate 21 to disengage from the first clamping plate 12.

[0067] Step 3: Next, engage the first clamping plate 12 and the second clamping plate 21 on the folded edge of the worker's clothes. Then, release the pressure on the fixed clamping plate 2. At this time, the linkage torsion spring 1102 releases torque, and the return spring 13 releases elasticity to push the fixed clamping plate 2 to move. This causes one end of the fixed clamping plate 2 to move the second clamping plate 21 closer to the first clamping plate 12, thereby clamping the second clamping plate 21 and the first clamping plate 12 on both sides of the folded edge of the clothes.

[0068] Step 4: Next, press the guide slide rods 34 on both sides of the outer block 3. The guide slide rods 34 slide along the inside of the guide groove. As the guide slide rods 34 move, they drive the guide slider 3401 to slide along the inside of the transverse groove. The guide slider 3401 presses the guide spring 3402 to make it contract and store force.

[0069] As the guide slide bar 34 moves, it presses the locking rod 3203, causing one end of the locking rod 3203 to slide along the guide slide groove and the inside of the guide groove. As the locking rod 3203 moves, it presses the limiting slide plate 3202 to slide along the inside of the limiting groove. As the limiting slide plate 3202 slides, it presses the positioning spring 3201 to contract and store force.

[0070] When the locking rod 3203 moves out of the inside of the guide slide groove, the fastening spring 33 releases its elastic force to push the limiting slide rod 32 to slide along the inside of the limiting slide groove. The limiting slide rod 32 drives the positioning block 31 to slide along the inside of the guide slide cavity, so that the bottom of the positioning block 31 is locked between the Bluetooth positioning work card 1 and the fixing clamp 2.

[0071] Next, the pressure on the guide slide bar 34 is released, and the guide slide bar 34 is reset under the action of the guide spring 3402.

[0072] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
