Description

Technical Field

[0001] The invention belongs to the technical field of metallurgy, in particular to a liquid level detection device for an emergency water tank. Background Art

[0002] The function of the emergency water tank is that when the water flow of the crystallizer is low, the one-way valve of the emergency water tank opens to ensure the water flow of the crystallizer and prevent the crystallizer copper tube from burning or exploding due to water outage. Therefore, the liquid level of the water tank is very important, so a level gauge is installed to take signals to facilitate daily inspections by maintenance personnel. However, the emergency water tank is installed on the roof of the workshop and is very close to the steam discharge port. The continuous casting steam is corrosive and can easily cause the level gauge to be damaged within half a year.

[0003] The liquid level gauge currently installed is of the flip-plate type, which is higher than the water tank. The liquid level gauge is installed on the outside of the water tank, and the accident water tank is installed on the roof of the workshop. The liquid level gauge can detect the distance between the water level inside the water tank and the liquid level gauge. By subtracting the detected distance from the water tank height, the water content inside the water tank can be obtained.

[0004] The existing radar level meter is directly installed to the bottom surface of the protective box by bolts, and it remains unchanged during assembly and disassembly. The radar level meter is inconvenient to adjust the angle, and the bottom transmitting device of the level meter is easily touched during assembly and disassembly, resulting in damage or inaccurate measurement results.

[0005] To this end, the present invention provides an emergency water tank liquid level detection device. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is: the liquid level detection device of an emergency water tank of the present invention comprises:

[0008] A protective box body; the bottom surface of the protective box body is provided with a bottom groove;

[0009] Radar level gauge;

[0010] A storage mechanism is provided inside the protective box and located on one side of the bottom groove. The storage mechanism includes two fixed plates, each of which is slidably connected to a slide seat. A third rotating shaft passes through the two slide seats and is rotatably connected to the slide seat. Both ends of the third rotating shaft are fixedly connected to spur gears. The bottom of the spur gear is meshed with a gear plate. The gear plate is fixed to the inner bottom surface of the protective box. The radar level meter is fixed to the third rotating shaft via a mounting seat.

[0011] Among them, one end between the two fixed plates is rotatably connected with a second rotating shaft, and a horizontal shaft is rotatably set on each fixed plate, and the horizontal shaft is threadedly connected to the slide seat, and the horizontal shaft is connected to the second rotating shaft through a worm gear assembly. By rotating the second rotating shaft, the third rotating shaft can be driven to slide along the fixed plate while driving the spur gear to rotate, so that the third rotating shaft rotates synchronously, and the radar level meter is stored in the protective box through the bottom groove.

[0012] Furthermore, each fixed plate is fixedly connected to a support plate at both ends, and the two ends of the horizontal axis are rotatably connected to the two support plates respectively. The horizontal axis is a threaded shaft, and the horizontal axis passes through the slide seat, which supports the horizontal axis through the support plate. When the horizontal axis rotates, it can drive the slide seat to slide along the fixed plate, providing power for the movement of the slide seat.

[0013] Furthermore, the worm gear assembly includes two worm segments fixedly arranged on the second rotating shaft, and a worm wheel is fixedly connected to one end of each of the transverse shafts. Each of the worm segments is meshedly connected with the worm wheel located on its adjacent side to drive the second rotating shaft, and the worm wheel is driven to rotate through the worm segment, so that the transverse shaft rotates to realize energy transfer, thereby providing power for storing the radar level meter in the protective box or releasing it from the protective box.

[0014] Furthermore, the two fixed plates are symmetrically arranged, and the fixed plates are both rectangular plate structures. A transverse groove is opened in the middle of the fixed plate, and one end of the slide is slidably arranged inside the transverse groove. The transverse groove can limit the moving direction of the slide so that the slide can only slide along the transverse groove, avoiding ensuring the straightness of the movement of the two slides and improving the stability of the movement.

[0015] Furthermore, one end of the second rotating shaft passes through the side wall of the protective box and the end is fixedly connected to the second turntable. A box door is provided on one side of the second turntable. The box door is rotatably connected to the protective box. By rotating the second turntable, the second rotating shaft can be driven to rotate, providing power for the operation of the storage mechanism. The design of the box door allows the box door to be opened after the storage mechanism stores the radar level meter into the protective box, thereby facilitating disassembly, assembly and maintenance of the radar level meter.

[0016] Furthermore, it also includes a height balancing mechanism, which is arranged on both sides of the interior of the protective box;

[0017] The height balancing mechanism includes a lifting plate symmetrically arranged inside the protective box body, and support legs are rotatably connected on both sides of the bottom of the lifting plate. A screw is passed through the middle of the lifting plate, and the screw is threadably connected to the lifting plate. The screw is rotatably arranged inside the protective box body, and limit rods are respectively provided on both sides of the screw. The limit rods slide through the lifting plate. The lifting plate can be driven up and down along the limit rods by rotating the screw. By adjusting the height positions of the two lifting plates, it can be applied to the inclined top surface of the water tank, thereby improving the applicability of the device. The two support legs can be rotated slightly, which further facilitates the fixing of the support legs to the top surface of the water tank.

[0018] Furthermore, a connecting shaft is provided between the two screws, the thread directions of the two screws are opposite, the connecting shaft is rotatably provided on the inner top wall of the protective box body, the two screws and the connecting shaft are fixedly connected with transmission wheels, and the three transmission wheels are connected by chain transmission;

[0019] The internal rotation of the protective box is provided with a first rotating shaft, and the first rotating shaft and the connecting shaft are both provided with bevel gears, and the two bevel gears are meshed and connected. One end of the first rotating shaft passes through the side wall of the protective box and the end is fixedly connected to the first turntable. When the height position of the support leg needs to be balanced, the first rotating shaft is driven to rotate by rotating the first turntable, and the connecting shaft is driven to rotate through the meshing transmission of the two bevel gears, and then the screws on both sides are driven to rotate through the chain transmission between the three transmission wheels. Since the thread directions of the two screws are opposite, the two lifting plates move in opposite directions of movement, which can adjust the support legs faster so that the support legs contact the inclined top surface of the water tank, which is convenient for adjusting the level of the protective box, so that the radar level gauge is in a vertical state, and the distance between the tip of the radar level gauge and the water level in the water tank in the vertical direction of its bottom can be measured, thereby improving the accuracy of the detection structure, saving the device fixing time, and improving work efficiency.

[0020] Furthermore, each of the lifting plates is provided with an adjustment slot at both ends, and a rotating shaft is fixed to both sides of the top of each support leg. The end of each rotating shaft away from the lifting plate is rotatably set on the inner wall of the adjustment slot, and the bottom surface of the protective box is provided with a rectangular slot for the support leg to pass through. By adjusting the angle between the support leg and the lifting plate, the device can adapt to the top surface structure of water tanks with different structures.

[0021] Furthermore, a water tank top wall fitting mechanism is provided at the bottom of the support leg, and the water tank top wall fitting mechanism includes a sleeve slidably sleeved on the bottom of the support leg, and a row of several threaded holes is provided on one side of the support leg, and a rotating rod is threadedly connected to the sleeve, and the rotating rod is fixedly connected to the third turntable at one end outside the sleeve. After adjustment by the height balancing mechanism, due to the limitation of the height balancing mechanism itself, the two support legs at the bottom of the same lifting plate are consistent in height. When the height positions on the same side of the water tank top wall are inconsistent, the sleeve is moved and the third turntable is rotated to make the rotating rod screw into the threaded hole, thereby fixing the position of the sleeve and the support leg, completing the function of compensating for small height differences, and having strong adaptability.

[0022] Furthermore, the two sides of the bottom of the sleeve are rotatably connected to the steering plates through support rods, and the bottoms of the two steering plates are commonly fixed with a fitting plate. A number of positioning holes are provided around the plate body of the fitting plate. When the support legs are connected to the inclined top surface of the water tank, the fitting plate is rotated to make the fitting plate fully fit with the inclined top surface of the water tank, and then fixed with bolts. This makes it more convenient to fix the support legs, and ensures the stability of the protective box body after fixation, thereby improving its service life.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention relates to an accident water tank liquid level detection device. When a radar liquid level meter needs to be repaired, the second rotating shaft can be rotated to drive the third rotating shaft to slide along the fixed plate, while driving the spur gear to rotate, so that the third rotating shaft rotates synchronously, and the radar liquid level meter is stored in the protective box through the bottom groove. The storage is convenient, and the self-locking property of the worm gear assembly can be used to ensure that the position of the radar liquid level meter is fixed after installation, and the angle can be adjusted to improve the accuracy of the detection result, and the radar liquid level meter is easy to disassemble and assemble, so as to solve the problem that the traditional radar liquid level meter is installed on the bottom surface of the protective box, and the bottom transmitting device of the liquid level meter is easily touched during disassembly and assembly, thereby causing damage or inaccurate measurement results.

[0025] 2. The present invention describes an accident water tank liquid level detection device, which drives the first rotating shaft to rotate by rotating the first turntable, drives the connecting shaft to rotate through the meshing transmission of the two bevel gears, and then drives the screws on both sides to rotate through the chain transmission between the three transmission wheels. Since the thread directions of the two screws are opposite, the two lifting plates move in opposite directions of movement, and the support legs can be adjusted more quickly so that the support legs contact the inclined top surface of the water tank, which facilitates the adjustment of the level of the protective box body, so that the radar level meter is in a vertical state, and can measure the distance between the tip of the radar level meter and the water level in the water tank in the vertical direction of its bottom, thereby improving the accuracy of the detection structure, while saving the time of fixing the device and improving work efficiency.

[0026] 3. The present invention relates to an emergency water tank liquid level detection device, which moves the sleeve and then rotates the third turntable to screw the rotating rod into the threaded hole, thereby fixing the position of the sleeve and the supporting leg, completing the function of compensating for small height differences, and has strong adaptability. It solves the problem that due to the limitation of the height balancing mechanism itself, the two supporting legs at the bottom of the same lifting plate are at the same height, and when the height positions on the same side of the water tank top wall are inconsistent, it is inconvenient to fix them.

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0038] Example 1

[0039] An accident water tank liquid level detection device described in an embodiment of the present invention utilizes a radar level gauge to reduce damage to the liquid level gauge caused by corrosive steam and extend the service life of the liquid level gauge. The originally installed liquid level gauge is of a flip-plate type, which is higher than the water tank and can only be installed on the outside of the water tank. A radar level gauge is now selected, which is small in size, easy to install, and corrosion-resistant. In addition, the price of the two level gauges is lower than that of the flip-plate type. The radar level gauge is now installed above the observation hole of the accident water tank, and a protective shell is made. The accident water tank is installed on the roof of the workshop. Each maintenance is a special high-altitude operation. It was originally replaced every six months, but now it has been changed to a radar level gauge, which is still in use after one and a half years, reducing operational risks and saving equipment maintenance costs.

[0040] like Figures 1 to 5 As shown, specifically, an accident water tank liquid level detection device according to an embodiment of the present invention includes a protective box body 1, a radar liquid level meter 7 and a storage mechanism 3; a bottom groove 5 is provided on the bottom surface of the protective box body 1 for the radar liquid level meter 7 to pass through; the storage mechanism 3 is arranged inside the protective box body 1 and is located on one side of the bottom groove 5, and the storage mechanism 3 includes two fixed plates 33, and a slide 37 is slidably connected to the two fixed plates 33. A third rotating shaft 34 passes through the two slides 37, and the third rotating shaft 34 is rotatably connected to the slide 37. Both ends of the third rotating shaft 34 are fixedly connected to a spur gear 341, and the bottom of the spur gear 341 is meshedly connected to a gear plate 342, and the gear plate 342 is fixedly connected to On the inner bottom surface of the protective box 1, the radar level meter 7 is fixed to the third rotating shaft 34 through the mounting seat 35; when the radar level meter 7 needs to be inspected, the two slides 37 are synchronously controlled to move on the fixed plate 33. Since the spur gears 341 at both ends of the third rotating shaft 34 are engaged with the gear plate 342, the third rotating shaft 34 rotates while moving, and then the mounting seat 35 rotates, so that the radar level meter 7 rotates while moving, and enters the interior of the protective box 1 through the bottom groove 5, which is convenient for the disassembly and assembly of the radar level meter 7, and solves the problem that the traditional radar level meter 7 is installed on the bottom surface of the protective box 1, and it is easy to touch the bottom transmitting device of the level meter during disassembly and assembly, which may cause damage or inaccurate measurement results.

[0041] Among them, one end between the two fixed plates 33 is rotatably connected with the second rotating shaft 32, and a horizontal shaft 36 is rotatably set on each fixed plate 33, and the horizontal shaft 36 is threadedly connected to the slide 37. The horizontal shaft 36 and the second rotating shaft 32 are connected to the horizontal shaft 36 through a worm gear assembly. By rotating the second rotating shaft 32, the third rotating shaft 34 can be driven to slide along the fixed plate 33 while driving the spur gear 341 to rotate, so that the third rotating shaft 34 rotates synchronously, and the radar level meter 7 is stored in the protective box 1 through the bottom groove 5. It is convenient to store, and the self-locking nature of the worm gear assembly can be used to ensure that the position of the radar level meter 7 is fixed after installation, and the angle can be adjusted to improve the accuracy of the detection results.

[0042] like Figure 4 As shown, both ends of each fixed plate 33 are fixedly connected to a support plate 331, and both ends of the horizontal shaft 36 are rotatably connected to the two support plates 331 respectively. The horizontal shaft 36 is a threaded shaft, and the horizontal shaft 36 passes through the slide 37. The support plates 331 support the horizontal shaft 36. When the horizontal shaft 36 rotates, it can drive the slide 37 to slide along the fixed plate 33, providing power for the movement of the slide 37.

[0043] like Figure 5 As shown, the worm gear assembly includes two worm segments 321 fixedly set on the second rotating shaft 32, and one end of each of the transverse shafts 36 is fixedly connected to a worm wheel 322. Each of the worm segments 321 is meshedly connected with the worm wheel 322 located on its adjacent side to drive the second rotating shaft 32 to rotate. The worm segment 321 drives the worm wheel 322 to rotate, so that the transverse shaft 36 rotates to realize energy transfer, thereby providing power for putting the radar level meter 7 into the protective box 1 or releasing it from the protective box 1.

[0044] like Figure 4 As shown, the two fixed plates 33 are symmetrically arranged, and the fixed plates 33 are both rectangular plate structures. A transverse groove 343 is opened in the middle of the fixed plate 33, and one end of the slide 37 is slidably arranged inside the transverse groove 343. The transverse groove 343 can limit the moving direction of the slide 37, so that the slide 37 can only slide along the transverse groove 343, avoiding ensuring the straightness of the movement of the two slides 37 and improving the stability of the movement.

[0045] like Figure 1 and Figure 2 As shown, one end of the second rotating shaft 32 passes through the side wall of the protective box 1 and the end is fixedly connected to the second turntable 31. A box door 4 is provided on one side of the second turntable 31. The box door 4 is rotatably connected to the protective box 1. By rotating the second turntable 31, the second rotating shaft 32 can be driven to rotate, providing power for the operation of the storage mechanism 3. The design of the box door 4 enables the box door 4 to be opened after the storage mechanism 3 stores the radar level meter 7 into the protective box 1, so as to facilitate the disassembly, assembly and maintenance of the radar level meter 7.

[0046] Example 2

[0047] like Figure 1 、 Figure 2 、 Figure 6 As shown, compared with Example 1, in order to solve the problem that most water tanks or house roofs need to be designed as inclined top surfaces so that rain, snow or dust do not accumulate on the top, and the traditional radar level meter 7 cannot be easily installed on the inclined top surface of the water tank or the house, another embodiment of the present invention is:

[0048] Specifically, the present invention further includes a height balancing mechanism 2, which is arranged on both sides of the interior of the protective box 1;

[0049] The height balancing mechanism 2 includes a lifting plate 26 symmetrically arranged inside the protective box 1, and the bottom two sides of the lifting plate 26 are rotatably connected to the support legs 9. A screw 27 is passed through the middle of the lifting plate 26, and the screw 27 is threadedly connected to the lifting plate 26. The screw 27 is rotatably arranged inside the protective box 1, and a limit rod 28 is respectively provided on both sides of the screw 27. The limit rod 28 slides through the lifting plate 26. By rotating the screw 27, the lifting plate 26 can be driven to move up and down along the limit rod 28. By adjusting the height position of the two lifting plates 26, it can be applied to the inclined top surface of the water tank or the house, thereby improving the applicability of the device. The two support legs 9 can be rotated slightly, which further facilitates the fixing of the support legs 9 to the top surface of the water tank.

[0050] like Figure 6 As shown, a connecting shaft 25 is provided between the two screws 27, and the thread directions of the two screws 27 are opposite. The connecting shaft 25 is rotatably provided on the inner top wall of the protective box body 1. The two screws 27 and the connecting shaft 25 are fixedly connected with a transmission wheel 24, and the three transmission wheels 24 are connected by a chain transmission; the internal rotation of the protective box body 1 is provided with a first rotating shaft 22, and the first rotating shaft 22 and the connecting shaft 25 are both provided with a bevel gear 23, and the two bevel gears 23 are meshed and connected. One end of the first rotating shaft 22 passes through the side wall of the protective box body 1 and the end is fixedly connected to the first turntable 21. When the height position of the support leg 9 needs to be balanced, the first turntable 21 is driven by rotating the first turntable 21. The first rotating shaft 22 is driven to rotate, and the meshing transmission of the two bevel gears 23 drives the connecting shaft 25 to rotate, and then the chain transmission between the three transmission wheels 24 drives the screws 27 on both sides to rotate. Since the thread directions of the two screws 27 are opposite, the two lifting plates 26 move in opposite directions, which can adjust the support legs 9 more quickly, so that the support legs 9 contact the inclined top surface of the water tank, and it is convenient to adjust the level of the protective box 1, so that the radar level meter 7 is in a vertical state, and the distance between the tip of the radar level meter 7 and the water level in the water tank in the vertical direction of its bottom can be measured, thereby improving the accuracy of the detection structure, saving the time of fixing the device, and improving work efficiency.

[0051] like Figure 1 and Figure 6 As shown, adjustment slots 29 are provided at both ends of each lifting plate 26, and rotating shafts are fixed on both sides of the top of each support leg 9. The end of each rotating shaft away from the lifting plate 26 is rotatably set on the inner wall of the adjustment slot 29, and the bottom surface of the protective box body 1 is provided with a rectangular slot 6 for the support leg 9 to pass through. By adjusting the angle between the support leg 9 and the lifting plate 26, the device can be adapted to the top surface structure of water tanks with different structures.

[0052] Example 3

[0053] like Figure 1 、 Figure 7 and Figure 8 As shown, compared with the second embodiment, in order to solve the problem that after adjustment by the height balancing mechanism 2, due to the limitation of the height balancing mechanism 2 itself, the two supporting legs 9 at the bottom of the same lifting plate 26 are at the same height, and when the height positions on the same side of the top wall of the water tank are inconsistent, it is inconvenient to fix. Another embodiment of the present invention is:

[0054] The bottom of the support leg 9 is provided with a water tank top wall fitting mechanism 8, and the water tank top wall fitting mechanism 8 includes a sleeve 82 slidably sleeved on the bottom of the support leg 9. A row of several threaded holes 86 are provided on one side of the support leg 9, and a rotating rod is threadedly connected to the sleeve 82. The end of the rotating rod located on the outside of the sleeve 82 is fixedly connected to the third turntable 81. After adjustment by the height balancing mechanism 2, due to the limitation of the height balancing mechanism 2 itself, the two support legs 9 at the bottom of the same lifting plate 26 are consistent in height. When the height position of the same side of the water tank top wall is inconsistent, the sleeve 82 is moved and the third turntable 81 is rotated to make the rotating rod screwed into the threaded hole 86, so that the position of the sleeve 82 and the support leg 9 is fixed, and the function of compensating for small height differences is completed, and the adaptability is strong.

[0055] like Figure 8 As shown, the two sides of the bottom of the sleeve 82 are rotatably connected to the steering plates 83 through support rods, and the bottoms of the two steering plates 83 are commonly fixed with a fitting plate 84. A number of positioning holes 85 are provided around the plate body of the fitting plate 84. When the support leg 9 is connected to the inclined top surface of the water tank, the fitting plate 84 is rotated to make the fitting plate 84 fully fit with the inclined top surface of the water tank, and then fixed by bolts. It is more convenient to fix the support leg 9, and the stability of the protective box body 1 after fixation is guaranteed, thereby improving the service life.

[0056] The working principle is that when the radar level gauge 7 needs to be repaired, the third rotating shaft 34 can be driven by rotating the second rotating shaft 32, and the worm gear 322 is driven to rotate by the worm segment 321, so that the horizontal shaft 36 rotates, and then the two slides 37 are synchronously controlled to move on the fixed plate 33. Since the spur gears 341 at both ends of the third rotating shaft 34 are meshed with the gear plate 342, the third rotating shaft 34 rotates while moving, and then the mounting seat 35 rotates, so that the radar level gauge 7 rotates while moving, and enters the interior of the protective box 1 through the bottom groove 5, which is convenient for disassembly and assembly of the radar level gauge 7, and solves the problem that the traditional radar level gauge 7 is installed on the bottom surface of the protective box 1, and it is easy to touch the bottom transmitting device of the level gauge during disassembly and assembly, which causes damage or inaccurate measurement results. In addition, the self-locking nature of the worm gear assembly can be used to ensure that the position of the radar level gauge 7 is fixed after installation and is not prone to deflection, thereby improving the accuracy of the detection results.

[0057] When the height position of the support leg 9 needs to be balanced, the first rotating shaft 22 is driven to rotate by rotating the first turntable 21, and the connecting shaft 25 is driven to rotate through the meshing transmission of the two bevel gears 23, and then the screw rods 27 on both sides are driven to rotate through the chain transmission between the three transmission wheels 24. Since the thread directions of the two screw rods 27 are opposite, the two lifting plates 26 move in opposite directions of movement, which can adjust the support leg 9 more quickly, so that the support leg 9 contacts the inclined top surface of the water tank, and it is convenient to adjust the level of the protective box body 1 so that the radar level gauge 7 is in a vertical state, and the distance between the tip of the radar level gauge 7 and the water level in the water tank in the vertical direction of its bottom can be measured, thereby improving the accuracy of the detection structure, saving the time of fixing the device, and improving work efficiency.

[0058] After adjustment by the height balancing mechanism 2, due to the limitation of the height balancing mechanism 2 itself, the two support legs 9 at the bottom of the same lifting plate 26 are at the same height. When the height positions of the top wall of the water tank on the same side are inconsistent, the sleeve 82 is moved and the third rotary disk 81 is rotated so that the rotating rod is screwed into the threaded hole 86, thereby fixing the position of the sleeve 82 and the support leg 9, completing the function of compensating for the slight height difference, and having strong adaptability.

[0059] When the support leg 9 is connected to the inclined top surface of the water tank, the fitting plate 84 is rotated so that the fitting plate 84 is fully fitted with the inclined top surface of the water tank, and then fixed with bolts. This makes it more convenient to fix the support leg 9, and ensures the stability of the protective box body 1 after fixation, thereby improving its service life.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments.
