Description

Technical Field

[0001] This application relates to the field of river management equipment technology, and more specifically, to a device for emptying internal condensate from the air bladders of inflatable rubber dams and air shield dams. Background Technology

[0002] Inflatable rubber dams and air-shield dams are commonly used water-retaining structures in hydraulic engineering, relying on inflated airbags to raise the dam's height and achieve water-retaining function. In actual operation, condensation can easily form inside the airbags due to environmental factors such as diurnal temperature differences and humidity variations.

[0003] Inflatable rubber dams and air-shield dams are widely used in water conservancy projects such as irrigation, flood control, and landscape water storage due to their advantages of simple construction, low cost, and flexible height adjustment. However, during long-term operation, the problem of condensation inside the airbags has gradually become prominent. Because the internal space of the airbag is relatively sealed and there is a temperature difference with the outside, water vapor easily condenses into water droplets on the inner wall of the airbag. Over time, this condensation accumulates, increasing the extra load on the airbag, reducing its service life, and accelerating the aging of the rubber material. Furthermore, it may cause uneven stress on the airbag, affecting the stability of the dam body. During critical periods such as flood season, it may even lead to localized deformation and leakage, posing safety hazards. Traditional methods often involve manually opening drainage valves periodically to drain the water, but this method is inefficient, increases labor intensity, and makes it difficult to accurately determine the timing of drainage.

[0004] To address the aforementioned issues, this application provides a device for draining internal condensate from the air bladders of inflatable rubber dams and air shield dams. Utility Model Content

[0005] One objective of this application is to provide a device for draining internal condensate from the air bladder of an inflatable rubber dam and an air shield dam, comprising a dam base, an internal rubber dam, a water collection trough, a rectangular groove at the top of the dam base, multiple discharge pipes fixedly connected between the rubber dam and the water collection trough, a water pump installed at the top of the dam base, a connecting pipe connecting the water pump and the water collection trough, two limiting rods fixedly connected to the inner bottom wall of the right end of the water collection trough, floats slidably sleeved on the outer sides of the two limiting rods, a fixed plate fixedly connected to the lower inner side of the rectangular groove, a sliding rod fixedly connected to the top of the float, the top end of the sliding rod penetrating the fixed plate and fixedly connected to the sliding plate, trigger rods fixedly connected to both the upper and lower sides of the sliding plate, a first trigger switch and a second trigger switch respectively installed above and below the sliding plate, and a controller fixedly connected to the top of the fixed plate.

[0006] Furthermore, the top of the fixing plate is symmetrically and detachably connected with rectangular rods, and a rectangular tube is slidably sleeved on the outside of the rectangular rods. An installation plate is sleeved on the outside of the rectangular tube, and the first trigger switch and the second trigger switch are respectively installed on opposite sides of the two installation plates.

[0007] Furthermore, a threaded hole is provided on the outer side of the rectangular tube, and a limit bolt is inserted into the internal thread of the threaded hole. A threaded hole is provided on the outer side of the mounting plate, and a locking bolt is inserted into the internal thread of the threaded hole.

[0008] Furthermore, the top of the fixing plate is symmetrically provided with a threaded groove, and a threaded post is threadedly inserted into the inside of the threaded groove. The top end of the threaded post is fixedly connected to the bottom end face of the rectangular rod.

[0009] Furthermore, a vertical rod is fixedly connected to the top of the fixed plate, and the end of the sliding plate away from the sliding rod is slidably sleeved on the outside of the vertical rod.

[0010] Furthermore, a cover plate is detachably connected to the upper inner side of the rectangular groove, and a rubber ring is provided on the top of the dam foundation, with the rubber ring fixedly connected to the outside of the cover plate.

[0011] Furthermore, the cover plate has an insertion hole, the top surface of the upright has a threaded groove, a fixing bolt is inserted into the insertion hole, and the fixing bolt is threaded into the threaded groove. A carrying rod is fixedly connected to the top of the cover plate.

[0012] The beneficial effects of this application are:

[0013] 1. Condensate inside the rubber dam is discharged into a collection tank through multiple discharge pipes. The collection tank collects the condensate inside the rubber dam. Two limit rods limit the movement of the float plate, allowing it to move smoothly. The float plate rises with the water level. The upward movement of the float plate drives the sliding rod, sliding plate, and trigger rod to move upward. When the water level is too high, the trigger rod, along with the floating sliding plate, contacts the first trigger switch. At this time, the controller detects the signal and controls the water pump to work with the connecting pipe to extract the condensate from the collection tank. No manual operation is required, which improves work efficiency and reduces the intensity of manual labor.

[0014] 2. Loosening the limiting bolt releases the fixation of the rectangular tube, causing the rectangular tube to slide on the outside of the rectangular rod, thereby moving the trigger switch and facilitating the adjustment of the trigger switch's position. This allows the water pump to be started as needed by adjusting the water level. Attached Figure Description

[0027] Example:

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This application discloses a device for draining internal condensate from the airbags of an inflatable rubber dam and an air shield dam. The device includes a dam base 1, a rubber dam 2 disposed inside the dam base 1, a water collection trough 7 formed inside the dam base 1, and a rectangular groove 12 formed at the top of the dam base 1. The rectangular groove 12 and the water collection trough 7 are connected. Multiple discharge pipes 8 are fixedly connected between the rubber dam 2 and the water collection trough 7. Condensate inside the rubber dam 2 is discharged into the water collection trough 7 through the multiple discharge pipes 8. A water pump 3 is installed at the top of the dam base 1. The water pump 3 and the water collection trough 7 are connected... A connecting pipe 6 connects the tanks 7. Two limiting rods 9 are fixedly connected to the inner bottom wall of the right end of the water collection tank 7. A float 10 is slidably sleeved on the outer side of the two limiting rods 9. The two limiting rods 9 limit the float 10, allowing the float 10 to move smoothly. The float 10 rises with the water level. The upward movement of the float 10 drives the sliding rod 11, the sliding plate 21, and the trigger rod 23 to move upward. When the water level is too high, the trigger rod 23 contacts the first trigger switch 19 as the sliding plate 21 floats. At this time, the controller... After the signal is detected, the controller 24 controls the water pump 3 to work with the connecting pipe 6 to extract the condensate inside the water collection tank 7. As the water pump 3 continues to pump water, the water level gradually drops, and the trigger rods 23 on the bottom surfaces of the float plate 10 and the sliding plate 21 also drop. When the trigger rod 23 on the bottom surface of the sliding plate 21 contacts the second trigger switch 20, the controller 24 detects the signal and controls the water pump 3 to stop working, thereby completing the operation of draining the condensate. No manual operation is required, which improves work efficiency and reduces the intensity of manual labor. A fixed plate 22 is fixedly connected to the lower side of the inside of the rectangular tank 12. A sliding rod 11 is fixedly connected to the top of the float plate 10. The top of the sliding rod 11 passes through the fixed plate 22 and is fixedly connected to the sliding plate 21. Trigger rods 23 are fixedly connected to both the upper and lower sides of the sliding plate 21. A first trigger switch 19 and a second trigger switch 20 are installed above and below the sliding plate 21, respectively. The controller 24 is fixedly connected to the top of the fixed plate 22. The water pump 3 and the two trigger switches are electrically connected to the controller 24.

[0029] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 A rectangular rod 14 is symmetrically and detachably connected to the top of the fixed plate 22. A rectangular tube 15 is slidably sleeved on the outside of the rectangular rod 14. A mounting plate 17 is sleeved on the outside of the rectangular tube 15. A first trigger switch 19 and a second trigger switch 20 are respectively installed on opposite sides of the two mounting plates 17. A threaded hole 1 is opened on the outside of the rectangular tube 15. A limit bolt 16 is inserted into the threaded hole 1. Loosening the limit bolt 16 releases the fixation of the rectangular tube 15, causing the rectangular tube 15 to slide on the outside of the rectangular rod 14, thereby driving the trigger switch to move. This facilitates the adjustment of the trigger switch position, allowing the water pump 3 to be started according to different water level heights as needed. A threaded hole 2 is opened on the outside of the mounting plate 17. A locking bolt 18 is inserted into the threaded hole 2. The top of the rectangular tube 15 is symmetrically provided with a threaded groove. A threaded post is inserted into the threaded groove. The top of the threaded post is fixedly connected to the bottom end face of the rectangular tube 14. The rectangular tube 14 is rotated to unscrew the threaded post from the inside of the threaded groove, so that the second trigger switch 20 and the mounting plate 17 are not located below the sliding plate 21. The rectangular tube 14 can then be disassembled. Then, the locking bolt 18 is turned to release the fixing of the mounting plate 17. The mounting plate 17 can then be removed from the outside of the rectangular tube 15 for inspection, maintenance or replacement. When the first trigger switch 19 needs to be inspected, maintained or replaced, the rectangular tube 14 is turned to remove it from the fixing plate 22. Then, the locking bolt 18 is turned to release the fixing of the mounting plate 17. The mounting plate 17 and the first trigger switch 19 can then be removed from the rectangular tube 14.

[0030] Please see Figure 4 and Figure 5 The top of the fixed plate 22 is fixedly connected to the upright 13. The end of the sliding plate 21 away from the sliding rod 11 is slidably sleeved on the outside of the upright 13. One end of the sliding plate 21 is fixedly connected to the top of the sliding rod 11, and the other end of the sliding plate 21 is slidably sleeved on the outside of the upright 13, thereby limiting the two ends of the sliding plate 21 and improving the stability of the sliding plate 21 when it is raised and lowered.

[0031] Please see Figure 2 and Figure 4A cover plate 4 is detachably connected to the upper side of the interior of the rectangular channel 12. A rubber ring is provided on the top of the dam foundation 1. The rubber ring improves the sealing between the cover plate 4 and the dam foundation 1, preventing water from flowing into the interior of the rectangular channel 12. The rubber ring is fixedly connected to the outside of the cover plate 4. An insertion hole is provided on the cover plate 4. A threaded groove is provided on the top surface of the upright 13. A fixing bolt 5 is inserted into the insertion hole, and the fixing bolt 5 is threaded into the threaded groove. The fixing bolt 5 is threaded into the threaded groove to fix the cover plate 4. At the same time, the removal of the cover plate 4 facilitates the inspection and maintenance of the components inside the rectangular channel 12. A carrying rod is fixedly connected to the top of the cover plate 4, which can be used to easily lift the cover plate 4.

[0032] The implementation principle of this application embodiment is as follows: the condensate inside the rubber dam 2 is discharged into the interior of the water collection tank 7 through multiple discharge pipes 8, thereby collecting the condensate inside the rubber dam 2 using the water collection tank 7;

[0033] Two limit rods 9 limit the float 10, allowing it to move smoothly. The float 10 rises with the water level, and its upward movement causes the sliding rod 11, sliding plate 21, and trigger rod 23 to move upward as well. When the water level is too high, the trigger rod 23, along with the floating sliding plate 21, contacts the first trigger switch 19. At this time, the controller 24 detects the signal and controls the water pump 3 to work with the connecting pipe 6 to pump out the condensate inside the water collection tank 7. As the water pump 3 continues to pump water, the water level gradually drops, and the trigger rod 23 on the bottom surface of the float 10 and sliding plate 21 also drops. When the trigger rod 23 on the bottom surface of the sliding plate 21 contacts the second trigger switch 20, the controller 24 detects the signal and controls the water pump 3 to stop working, thus completing the operation of draining the condensate without manual operation, improving work efficiency and reducing labor intensity.
