Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic structures, and in particular relates to a dock flood control door water stopping device and a use method thereof. Background Art

[0002] The docks of a shipyard are generally located near the river or the sea, where there are usually flood seasons. Therefore, it is necessary to set up flood control walls near the river or the sea. There are flood control gates in the flood control walls, and the purpose of flood control can be achieved by closing the flood control gates during the flood season.

[0003] The shipyard needs to use the crane at the dock to lift and land the materials transported by water. However, the track of the crane interferes with the flood control gate. Therefore, when manufacturing the flood control gate, a track gap will be reserved according to the actual position of the crane track on site to avoid interference with the crane track when the flood control gate is closed. However, the gap will make it impossible to completely close the flood control gate when it is closed. During the flood season, river water or sea water will flow in from the gap, which greatly reduces the role of the flood control gate. Usually, the solution to this problem is to use sandbags to block the gap to meet the closing function of the flood control gate. This method can play a certain role, but the speed at which river water or sea water flows into the gap is relatively fast, and the effect is not very obvious.

[0004] After searching, the Chinese invention application document with the existing publication number CN115419015A discloses a flood control door sealing device for a crane track, "including a flood control door body, a first sealing member and a plurality of filling members, a sealing hole for the crane track to pass through is opened at the bottom of the flood control door body, and the plurality of filling members are respectively sealed in the grooves on both sides of the crane track, and the first sealing member is located in the sealing hole and pressed between the flood control door body and the plurality of filling members and the crane track." However, the flood control function of the device still relies on the sealing effect of the separate and independent filling materials and the first sealing member, and the separation and independence will still affect the fitting density between the crane track and the flood control door, especially when the water flow is turbulent and the impact force is large during the flood season, it will cause deviation, and the problem of water leakage of the flood control door cannot be avoided, which has certain limitations.

[0034] Example 2

[0035] This embodiment provides a method for using a dock flood control door water stop device using the embodiment 1, comprising the following steps:

[0036] S0, such as Figure 1 As shown, before installing the water-stop device, confirm that there is no debris on the crane track 3 within the range of the prepared installation position of the flood control door 5. If there is any debris, clean it up in advance.

[0037] S1. Hoist the short water-stop board 12 and the long water-stop board 11 to the prepared installation position of the flood control door 5 on the crane track 3, and then vertically clamp the short water-stop board 12 and the long water-stop board 11 on the crane track 3. According to the flood and typhoon warning, when the flood season is coming and the dock flood control door 5 needs to be closed, prepare the crane in place in advance and take out the water-stop device from the storage position of the water-stop device.

[0038] S1-1, hoist the short water-stop plate 12 to the prepared installation position range of the flood control door 5 on the crane track 3, adjust the angle direction and position of the short water-stop plate 12, so that the short water-stop plate 12 is vertically embedded in the crane track 3 through the second notch 132.

[0039] like Figure 2 As shown, in the present embodiment, first, a shackle 8 with a hanging rope 6 is installed on the second lifting hole 121, and the water-stop short plate 12 is lifted steadily by a crane and moved along the length direction of the crane rail 3 to the range of the prepared installation position of the flood control door 5; then, by adjusting the angle of the water-stop short plate 12, the water-stop short plate 12 is rotated to be perpendicular to the length direction of the crane rail 3; at the same time, the position of the water-stop short plate 12 is adjusted, and the water-stop short plate 12 is moved to a position about 500 mm away from the prepared installation position of the flood control door 5, and the inner side surface of the lower end of the water-stop short plate 12 is tightly fitted to the outer side surface of the crane rail 3; after the water-stop short plate 12 is adjusted into place, the crane unhooks and unfastens the shackle 8 on the second lifting hole 121, at this time, the water-stop short plate 12 is vertically embedded in the crane rail 3 through the second slot 132.

[0040] S1-2, hoist and adjust the angle direction and position of the long water-stop plate 11 until the front end surface of the long water-stop plate 11 fits with the rear end surface of the short water-stop plate 12, and the long water-stop plate 11 is vertically embedded in the crane rail 3 through the first notch 131.

[0041] like Figure 3 As shown, in the present embodiment, first, a shackle 8 with a lifting rope 6 suspended thereon is installed on the first lifting hole 111, and the long water-stop plate 11 is lifted stably by a crane and moved along the length direction of the crane rail 3 to the rear end face close to the short water-stop plate 12; then, the long water-stop plate 11 is rotated to be perpendicular to the length direction of the crane rail 3 by adjusting the angle orientation of the long water-stop plate 11; at the same time, the position of the long water-stop plate 11 is adjusted so that the front end face of the long water-stop plate 11 is fitted with the rear end face of the short water-stop plate 12, and the inner side face of the lower end of the long water-stop plate 11 is tightly fitted with the outer side face of the crane rail 3. At this time, the long water-stop plate 11 is vertically embedded in the crane rail 3 through the first slot 131.

[0042] S2. Lock and fix the long water-stop plate 11 and the short water-stop plate 12 to form a blocking structure 1, and adjust the position of the blocking structure 1 until the rear end face of the blocking structure 1 is close to the plane where the front end face of the prepared installation position of the flood control door 5 is located.

[0043] like Figure 4 As shown, after the long water-stop plate 11 is adjusted into place, the fixing hole 112 of the long water-stop plate 11 and the second lifting hole 121 of the short water-stop plate 12 are locked and fixed by the fastener 4, so that the long water-stop plate 11 and the short water-stop plate 12 are assembled to form a blocking structure 1, and the blocking structure 1 is pulled horizontally by a crane using the shackle 8 installed on the first lifting hole 111 until the rear end face of the blocking structure 1 is close to the plane where the front end face of the prepared installation position of the flood control door 5 is located. After the blocking structure 1 is adjusted into place, the crane unhooks and unfastens the shackle 8 on the second lifting hole 121. In this embodiment, the fastener 4 adopts a fixing bolt 41 and a fixing nut 42.

[0044] S3, hoisting the flood control door 5 to the preparatory installation position of the flood control door 5, and installing the blocking structure 1 on the flood control door 5 to complete the installation of the water stopping device.

[0045] like Figure 4 As shown, the flood control door 5 is hoisted by a crane to the pre-installation position of the flood control door 5 on the crane track 3. At this time, the front end face of the flood control door 5 is successfully fitted with the rear end face of the blocking structure 1, and the rear end face of the flood control door 5 is fitted with the front end face of the ground 7. The fastener 4 and the second hoisting hole 121 on the water stop long plate 11 are used to fix the water stop long plate 11 in the installation groove on the flood control door 5, thereby fastening the blocking structure 1 to the flood control door 5 and completing the installation of the water stop device. In this embodiment, the second hoisting hole 121 and the installation groove are locked and fixed by fastening bolts, and a gasket is provided between the second installation hole and the fastening bolt to further increase the stability of the installation.

[0046] In this embodiment, the design of the blocking structure 1 cleverly utilizes the fit of the long water-stopping plate 11 and the short water-stopping plate 12 to form a tight sealing system. However, due to the front-to-back positional relationship between the long water-stopping plate 11 and the short water-stopping plate 12, Figure 4 As shown, there is a side seam between the short water-stop plate 12 and the track notch 51 of the flood control door 5, and the width of the side seam is the same as the thickness of the long water-stop plate 11. Although in theory the side seam provides a potential infiltration path for water flow, in actual work, by reducing the thickness of the long water-stop plate 11 and increasing the length of the short water-stop plate 12 on one side of the side seam, combined with the special position and design of the side seam between the sides, the overall sealing structure 1 can still have a high impermeability under the impact of water flow during flood season, and has good water-stopping performance.

[0047] In another embodiment, in order to further achieve complete sealing, when there is a side seam between the water-stopping device and the track gap 51 of the flood control gate 5, the side seam is sealed with sealants such as sandbags to complete the sealing of the track gap 51 of the flood control gate 5. Through the sealing of the sealants, a tighter waterproof barrier can be formed, which can not only fill any tiny gaps, but also provide additional physical pressure to enhance the sealing effect between the water-stopping device and the flood control gate 5. At the same time, the dual protection mechanism of the natural water-stopping characteristics of the side seam and the physical sealing of the sandbag is combined to ensure that the flood control gate 5 can effectively prevent the infiltration and backflow of water when facing the challenge of water flow during the flood season. In other embodiments, a folding plate is further provided on the short water-stop plate 12, and the folding plate is located at the outer edge of the short water-stop plate 12, and the rear end face of the folding plate is flush with the rear end face of the long water-stop plate 11, that is, the folding plate extends backward to fit the front end face of the flood control door 5. Preferably, the folding plate is perpendicular to the front end face of the flood control door 5, so that the blocking structure 1 can be completely sealed when installed on the flood control door 5, and no side seams exist, and the stability of the structure is ensured, thereby completing the blocking of the track gap 51 of the flood control door 5. By improving the structure of the short water-stop plate 12, the operating steps of sealing the side seams with sealants such as sandbags are omitted, thereby further improving the convenience of installation and use, and being able to respond to flood season warnings more quickly. In addition, due to the integrity of the blocking structure 1, the stability and flood control safety are improved.
