Description

Technical Field

[0001] This utility model relates to the field of foundation pit water level alarm technology, specifically a foundation pit water level alarm device. Background Technology

[0002] In vertical shafts, hoists are needed to lift materials. The hoist is installed by digging a pit and then placing the hoist inside. In harsh environments, water may accumulate in the pit, and high water levels can affect the hoist. Therefore, an alarm device is needed to detect the water level and automatically issue an alarm.

[0003] Currently, during the material transport process of hoists, to prevent accidents, an automatic alarm is required when the water level in the hoist pit is too high. This alarm interlocks with the hoist's main control panel, stopping operation and eliminating safety hazards. Therefore, an automatic alarm device is indispensable in the use of hoists. However, in existing technology, due to the special nature of the pit, the alarm device uses ropes to suspend a water level monitoring instrument inside the pit to detect the water level. The water level monitoring instrument is connected to an alarm; the instrument's monitoring of the water level triggers the alarm, which then interlocks with the main control panel to prevent accidents. However, because the water level monitoring instrument is suspended by ropes, it is prone to swaying, affecting its ability to monitor the water level. Furthermore, the swaying can easily damage the instrument and further impair water level monitoring. Therefore, this invention proposes a pit water level alarm. Utility Model Content

[0004] The purpose of this utility model is to provide a foundation pit water level alarm to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a foundation pit water level alarm, including a base, a support frame fixedly connected to the base, a rotating shaft rotatably connected to the support frame, a rope reel fixedly connected to the outer side of the rotating shaft, a rope installed on the rope reel, a gravity block fixedly connected to the bottom end of the rope, and an alarm installed on the base.

A fixing component for fixing the fixing plate is installed inside the fixing plate, and a connecting rod is fixedly connected to the outer side of the sleeve. A water level monitor is fixedly connected to the end of the connecting rod, and a protective component for protecting the water level monitor is installed on the outer side of the water level monitor, which facilitates the protection of the water level monitor and improves the stability of the water level monitor.

[0005] Preferably, the protective component includes a protective tube sleeved on the outside of the water level monitor, a floating disk sleeved on the outer side of the protective tube fixedly connected to the bottom end of the protective tube, a connecting ring slidably connected to the outer side of the protective tube, a fixing rod fixedly connected to the fixing disk fixedly connected to the connecting ring, a sliding block fixedly connected to the connecting rod slidably connected to the protective tube, and an elastic element installed between the water level monitor and the protective tube to facilitate the protection of the water level monitor and prevent damage during fall.

[0006] Preferably, the elastic element includes a sliding column fixedly connected to the water level monitor, the sliding column being slidably connected to the protective pipe, and a tension spring being fixedly connected between the water level monitor and the protective pipe to facilitate the reset of the protective pipe.

[0007] Preferably, the fixing component includes multiple sets of threaded sleeves that are slidably connected to the fixing discs. The multiple sets of threaded sleeves are symmetrically and circumferentially arranged in the two sets of fixing discs. One end of each threaded sleeve is fixedly connected to a compression plate, and a threaded post that is rotatably connected to the fixing disc is threaded inside the threaded sleeve. The end of the threaded post is connected to a rotating component for driving the threaded post to rotate, which facilitates fixing the rope to the fixing disc.

[0008] Preferably, the rotating component includes a rotating tube sleeved on the outer side of the rope, a handle fixedly connected to one end of the rotating tube, and a connecting disc sleeved on the outer side of the rope fixedly connected to the other end of the rotating tube. A gear ring rotatably connected to the connecting disc is fixedly connected to the end of the connecting disc. Multiple sets of spur gears mesh on the gear ring, and the multiple sets of spur gears are respectively fixedly connected to multiple sets of threaded columns. The spur gears are rotatably connected to the fixed disc, which facilitates the movement of the threaded columns.

[0009] Preferably, the outer surface of the throttle is provided with anti-slip texture to increase friction during rotation, thereby facilitating the rotation of the throttle.

[0010] Preferably, the surface of the extrusion plate that contacts the rope is provided with an anti-slip pad to increase the friction between the extrusion plate and the rope, thereby facilitating the fixing of the fixing plate and the rope.

[0011] The utility model has at least the following beneficial effects:

[0012] This utility model provides a foundation pit water level alarm. When monitoring the water level inside the foundation pit, the tension between the fixing plate and the rope is adjusted by the action of the fixing component. Thus, the fixing plate and the rope are loosened by the action of the fixing component. At this time, the position of the water level monitor is adjusted by moving the position of the fixing plate, thereby adjusting the water level monitor to a suitable position. Then, the rotation of the rope reel causes the rope to descend, which in turn causes the gravity block to descend. When the gravity block contacts the bottom of the foundation pit, the rope is tightened to make the rope taut, thereby preventing the bottom end from being suspended in the air. This prevents the water level monitor from shaking, thus maintaining the stability of the water level monitor for water level monitoring and avoiding damage caused by shaking.

A sleeve 8 is fitted on the outer side of the rope 5, and a fixing plate 9 fitted on the outside of the rope 5 is fixedly connected to both the upper and lower ends of the sleeve 8. A fixing element 10 for fixing the fixing plate 9 is installed inside the fixing plate 9, and a connecting rod 11 is fixedly connected to the outer side of the sleeve 8. A water level monitor 12 is fixedly connected to the end of the connecting rod 11, and a protective element 13 for protecting the water level monitor 12 is installed on the outer side of the water level monitor 12.

[0022] The protective component 13 includes a protective tube 14 sleeved on the outside of the water level monitor 12. A floating disk 15 sleeved on the outer side of the protective tube 14 is fixedly connected to the bottom end of the protective tube 14. A connecting ring 16 is slidably connected to the outer side of the protective tube 14. A fixing rod 17 fixedly connected to the fixing disk 9 is fixedly connected to the connecting ring 16. A sliding block 18 fixedly connected to the connecting rod 11 is slidably connected to the protective tube 14. An elastic component 19 is installed between the water level monitor 12 and the protective tube 14. The elastic component 19 includes a sliding column 20 fixedly connected to the water level monitor 12. The sliding column 20 is slidably connected to the protective tube 14. A tension spring 21 is fixedly connected between the water level monitor 12 and the protective tube 14.

[0023] The fixing component 10 includes multiple sets of threaded sleeves 22 that are slidably connected to the fixing disks 9. The multiple sets of threaded sleeves 22 are symmetrically and circumferentially arranged within the two sets of fixing disks 9. One end of each threaded sleeve 22 is fixedly connected to a pressing plate 23, and a threaded post 24 that is rotatably connected to the fixing disk 9 is threaded inside the threaded sleeve 22. The end of the threaded post 24 is connected to a rotating component 25 for driving the threaded post 24 to rotate. The rotating component 25 includes a rotating tube 26 sleeved on the outer side of the rope 5. The end of the rotating tube 26 is fixedly connected to a handle 27, and the other end of the rotating tube 26 is fixedly connected to a connecting disk 28 sleeved on the outer side of the rope 5. The end of the connecting disk 28 is fixedly connected to a gear ring 29 that is rotatably connected to the fixing disk 9. Multiple sets of spur gears 30 mesh on the gear ring 29. The multiple sets of spur gears 30 are fixedly connected to the multiple sets of threaded posts 24, and the spur gears 30 are rotatably connected to the fixing disk 9.

[0024] In this design, the outer surface of the throttle 27 is provided with anti-slip texture to increase the friction during rotation, thereby facilitating the rotation of the throttle 27. The surface of the extrusion plate 23 that contacts the rope 5 is provided with an anti-slip pad to increase the friction between the extrusion plate 23 and the rope 5, thereby facilitating the fixing of the fixing plate 9 and the rope 5.

[0025] Working principle:

[0026] During installation, first, rotating the handle 27 causes the rotating tube 26 to rotate, which in turn rotates the connecting plate 28. The rotation of the connecting plate 28 causes the gear ring 29 to rotate, which in turn rotates the spur gear 30, which in turn rotates the threaded column 24. This causes the threaded sleeve 22 to move, which in turn moves the extrusion plate 23. The movement of the extrusion plate 23 moves it away from the rope 5. At this point, adjusting the position of the fixing plate 9 allows adjustment of the water level monitor 12. Once the water level monitor 12 is in the appropriate position, rotating the handle 27 again in the opposite direction causes the rotating tube 26 to rotate... The moving connecting plate 28 rotates in the opposite direction, which causes the gear ring 29 to drive the flat gear 30 to rotate in the opposite direction. At this time, the threaded column 24 drives the extrusion plate 23 to move forward and extrude the rope 5. Therefore, the extrusion action of the extrusion plate 23 makes the fixed plate 9 and the rope 5 fixedly connected. At this time, the gravity block 6 is placed inside the pit 31, and the rope disc 4 is slowly rotated to make the gravity block 6 move down. When the gravity block 6 moves down and contacts the bottom of the pit 31, the rope 5 is tightened. At this time, the bottom of the rope 5 is not in a suspended state, but is in a taut state due to the pull of the gravity block 6 and the rope disc 4. Therefore, the rope 5 will not swing arbitrarily, which will prevent the water level monitor 12 from swinging arbitrarily and improve its monitoring stability.

[0027] During the monitoring process, as the water level gradually rises, the buoyancy of the water will cause the floating plate to rise, which in turn will cause the protective pipe 14 to rise. When the bottom of the floating plate 15 is flush with the bottom of the water level monitor 12, it indicates that the water level is too high. The alarm 7 will sound an alarm and simultaneously interlock the main control panel of the hoist to prevent accidents. The protective pipe 14 also helps to protect the water level monitor 12 and prevent it from being damaged during the descent.
