Description

Technical Field

[0001] The utility model relates to the technical field of ship lock maintenance flat door, in particular to a water stopping device for ship lock maintenance flat door. Background Art

[0002] When inspecting the reverse arc gate of the ship lock, it is necessary to drop the inspection flat gate. If the inspection flat gate does not have a good water-blocking effect and there is a large leakage, it will take too long to drain the valve well and the lock chamber, seriously affecting the realization of the inspection period and the safety of construction personnel's use of fire and electricity. During the inspection, the leakage is too large, and the deep well pump needs to be started frequently to drain water to ensure the safe and smooth progress of the inspection work, which causes the workload of the operators responsible for the deep well pumping and drainage operation to be high. Due to the large leakage, it is often necessary to pump and drain once every 3 hours during non-construction periods, and pump and drain once every 15 minutes during the bottom water stop inspection period; if the water is not pumped and drained in time, the water level in the valve well will be higher than the external river water, which will cause damage to the reverse support of the flat gate and failure of the flat gate to block water; frequent pumping and drainage will cause the deep well pump to start and stop frequently, and reduce the service life of the deep well pump.

[0003] The probability of poor water blocking effect after the maintenance flat door is lowered is high. At present, there have been many cases where the flat door has a large leak that affects the maintenance. The pumping and drainage of the lock chamber is one of the key projects of the ship lock overhaul. For the overhaul project that requires draining the lock chamber, if there is a large leak when the flat maintenance door is used to block water, it will have a serious impact on the ship lock maintenance period and the safety of valve equipment maintenance. Therefore, it is necessary to improve the sealing performance of the water stop device on the maintenance flat door. Utility Model Content

[0030] Embodiment 1:

[0031] See also Figure 1-5 A flat door water-stopping device for ship lock maintenance includes a top water-stopping structure, a side water-stopping structure and a bottom water-stopping structure for installation on the flat door 10, the top water-stopping structure is used to be installed on the top of the flat door 10, the side water-stopping structure is used to be installed on both sides of the flat door 10, and the bottom water-stopping structure is used to be installed on the bottom of the flat door 10. The top water-stopping structure and the side water-stopping structure each include a first sealing strip 20, the first sealing strip 20 includes a sealing portion 21 and a mounting portion 22 connected to the sealing portion 21, and a first sealing strip 20 is provided on a side of the mounting portion 22 away from the flat door 10. A pressing plate 13, a first bolt 14 passes through the first pressing plate 13 and the mounting portion 22 and is connected to the flat door 10, a sealing portion 21 is higher than the mounting portion 22, and an extension portion 23 extending outward is provided on the water-facing side of the sealing portion 21; the bottom water-stop structure includes a second sealing strip 30, a second pressing plate 15 is provided on the side of the second sealing strip 30 away from the flat door 10, a second bolt 16 passes through the second pressing plate 15 and the second sealing strip 30 and is connected to the flat door 10, and an extension portion 31 extending outward is provided on the water-facing side of the lower end of the second sealing strip 30. By providing the extension portion 23 on the sealing portion 21 of the first sealing strip 20 and the extension portion 31 on the second sealing strip 30, the sealing performance of the first sealing strip and the second sealing strip when in use is improved.

[0032] In this embodiment, the first sealing belt 20 in the top water-stopping structure and the side water-stopping structure is a P-shaped structure, and the second sealing belt 30 in the bottom water-stopping structure is a flat plate structure. The first sealing belt 20 and the second sealing belt 30 are both made of rubber. An extension portion 23 is provided on the first sealing belt 20, and an extension portion 31 is provided on the second sealing belt 30. The first sealing belt 20 contacts the side of the track plate 51, and the second sealing belt 30 contacts the seat plate 52 at the bottom of the door groove 50. The flexible extension portion 23 and the extension portion 31 can better adhere to the track plate 51 and the seat plate 52 under the action of water pressure, thereby improving the sealing performance of the first sealing belt and the second sealing belt when in use.

[0033] Embodiment 2:

[0034] See also Figure 6 The end of the extension portion 23 is provided with a plurality of steps 231 to improve the flexibility of the end of the extension portion 23 and improve the sealing performance. Figure 6 In the embodiment, the step 231 enables the end of the extension portion 23 to form a multi-layer structure, which is more conducive to sealing.

[0035] Embodiment three:

[0036] See also Figure 5-9 The sealing portion 21 of the first sealing strip 20 is provided with a cavity 24 to improve the flexibility of the sealing portion 21 and make the sealing portion 21 more elastic, so as to facilitate deformation and insertion into the door groove 50. When inserted into the door groove 50, the sealing portion 21 elastically abuts against the door groove 50, so that the flat door 10 is sealed with the door groove 50.

[0037] Embodiment 4:

[0038] See also Figure 7 The sealing portion 21 is provided with a symmetrical portion 25 on one side symmetrical to the extension portion 23. The symmetrical portion 25 is symmetrically designed with the extension portion 23 and is in an "eight" shape. After the flat door 10 is installed in the door groove 50, the extension portion 23 will be deflected and deformed upward after being squeezed, while the symmetrical portion 25 will be deflected and deformed downward. The extension portion 23 and the symmetrical portion 25 are subjected to opposite forces, so that the extension portion 23 can be more stably pressed against the track plate 51, thereby improving the sealing effect.

[0039] Embodiment five:

[0040] See also Figure 8On the sealing part 21, a pressing part 26 is provided between the extension part 23 and the symmetrical part 25. When the pressing part 26 is pressed, the sealing part 21 in the area between the extension part 23 and the symmetrical part 25 will be deformed toward the cavity 24. Since the area between the extension part 23 and the symmetrical part 25 of the sealing part 21 is an arc, when the sealing part 21 is deformed toward the cavity 24, it is equivalent to increasing the distance between the extension part 23 and the symmetrical part 25. At this time, the extension part 23 and the symmetrical part 25 will be further pressed against the track plate 51, thereby improving the sealing performance.

[0041] Furthermore, the symmetrical portion 25 is provided with an exhaust hole 251 to facilitate exhaust of the area between the extended portion 23 and the symmetrical portion 25 during extrusion deformation.

[0042] Embodiment six:

[0043] See also Fig. 9 A connecting rib 32 is also provided between the second sealing strip 30 and the extension portion 31. When the second sealing strip 30 is pressed downward, the extension portion 31 is prevented from tilting up, and the connecting rib 32 pulls the extension portion 31 inward, so that the extension portion 31 is pressed downward against the seat plate 52, thereby improving the sealing performance. In this embodiment, the connecting ribs 32 are arranged at intervals.

[0044] The working principle or action process of the utility model is as follows:

[0045] After the flat door 10 is installed in the door groove 50, the second sealing strip 30 is pressed against the seat plate 52. Figure 4 The extension portion 31 at the lower end of the second sealing belt 30 extends out and, under the action of water pressure, fits with the seat plate 52 of the door groove 50, so that the second sealing belt 30 forms a two-level sealing effect.

[0046] See also Figure 3 The first sealing strip 20 is fitted with the track plate 51 of the door groove 50 to form a seal. When the first sealing strip 20 contacts the track plate 51, the extension portion 23, the symmetrical portion 25 and the top pressure portion 26 are simultaneously against the track plate 51. Since the sealing portion 21 is in an arc shape in the area between the extension portion 23 and the symmetrical portion 25, when the top pressure portion 26 is against one side of the cavity 24, the sealing portion 21 is deformed toward the side of the cavity 24. At this time, the extension portion 23 tends to rotate clockwise, and the symmetrical portion 25 tends to rotate counterclockwise, so that the extension portion 23 will further press against the track plate 51, thereby improving the sealing performance.
