Description

Technical Field

[0001] The invention relates to the technical field of hydraulic gates, and in particular to a horizontally pulled upward-flipping gate water gate structure. Background Art

[0002] The up-flip gate is a commonly used gate type in water conservancy projects. The up-flip gate is generally composed of a water-retaining gate leaf structure and a horizontal bottom shaft or support hinge. The gate rotates around a fixed horizontal bottom shaft or support hinge. In the non-water-retaining state, the gate lies flat on the bottom of the river. In the water-retaining state, the gate rotates around the horizontal bottom shaft or support hinge to achieve the water-retaining function. Compared with other gate types, the up-flip gate has significant advantages such as reasonable structural force, safe and controllable opening and closing, fast opening and closing speed, no impact on navigation during operation, and small project footprint. However, its disadvantages are also obvious: the gate is located underwater for a long time, which makes maintenance difficult. The gate needs to be installed on the riverbed during the construction period, which has a certain impact on navigation during the construction period.

[0003] Horizontal sliding doors are generally used in ship lock projects. Since the flow area of ​​the river is gradually narrowed until no flow occurs during the opening and closing process of the horizontal sliding doors, they generally need to be opened and closed in still water, and are more difficult to open and close under moving water conditions.

[0004] Therefore, the applicant has found a solution to the above-mentioned problem through beneficial exploration and research, and the technical solution to be introduced below is produced in this context. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a horizontal pull type flip door water gate structure to solve the above problems in view of the above shortcomings and defects of the prior art.

[0006] The technical problem to be solved by the present invention can be achieved by adopting the following technical solutions:

[0007] A horizontal pull type flip door water gate structure, characterized by comprising:

[0008] The gate and warehouse structure is set on both sides of the central river channel;

[0009] An upward-turning door structure movably arranged in the door storage structure and used for blocking water;

[0010] a gate sluice gate movably arranged on the gate structure and located between the gate structure and the center of the river channel and used to isolate the water flow of the river channel, and

[0011] A sluice sill is arranged at the center of the river channel and cooperates with the upward-flipping door module.

[0012] In a preferred embodiment of the present invention, the flip door structure includes a steel shell base arranged on the door garage structure, an flip door body movably arranged on the steel shell base and used to flip up to block water, and a roller slidably arranged on the bottom of the steel shell base and slidingly cooperated with the door garage structure.

[0013] In a preferred embodiment of the present invention, the flip-up door structure further comprises a base anti-slip key which is arranged at the bottom of the steel shell base and is used to prevent the flip-up door structure from deviating to both sides as a whole.

[0014] In a preferred embodiment of the present invention, a ballast water tank that can be filled and drained is provided inside the steel shell base, the upward flip door body adopts a steel shell empty box structure, the upward flip door body is movably connected to the steel shell base through a hinge structure, and an air filling and exhaust pipe for enabling the upward flip door body to flip upward is provided inside the upward flip door body.

[0015] In a preferred embodiment of the present invention, the door garage structure includes a door garage and a door garage bottom plate, the door garage adopts a reinforced concrete dock structure, the foundation of the door garage is provided with a pile foundation, and a roller track cooperating with the roller is provided on the door garage bottom plate.

[0016] In a preferred embodiment of the present invention, a limit stopper cooperating with the base anti-slip key is provided on the inner side of the door garage.

[0017] In a preferred embodiment of the present invention, the sill of the water gate adopts a reinforced concrete hollow box structure, and the upper surface of the sill of the water gate is provided with a water gate track that cooperates with the roller.

[0018] In a preferred embodiment of the present invention, both sides of the top of the bottom sill of the sluice are provided with anti-slip tooth sills cooperating with the anti-slip keys of the base.

[0019] In a preferred embodiment of the present invention, both sides of the top of the sluice sill are provided with stone-blocking grilles for intercepting stones or garbage on the river bottom, and the stone-blocking grilles are arranged on the outside of the anti-slip tooth sill.

[0020] In a preferred embodiment of the present invention, anti-seepage steel plate columns are provided on both sides of the sill of the water gate, and the outer sides of the anti-seepage steel plate columns are backfilled with large stones.

[0021] Due to the adoption of the above technical solution, the beneficial effect of the present invention is that the present invention combines the advantages of traditional horizontal sliding doors and flip doors while avoiding the disadvantages of traditional horizontal sliding doors and flip doors, and has the following significant advantages: 1. It solves the problem that traditional flip doors are located underwater for a long time and are difficult to inspect and maintain on a daily basis. During daily inspection and maintenance, the staff enters the gatehouse to inspect the flip door structure. When an overhaul is required, the gate of the gatehouse can be opened to allow water to enter the gatehouse, and the water in the ballast water tank of the steel shell base can be emptied. At this time, the buoyancy of the flip door structure is greater than the gravity, and the flip door structure floats, and the flip door structure can be directly towed to the dock for overhaul; 2. It solves the problem that the traditional horizontal sliding door opening and closing process has too much water blocking and cannot be opened and closed with moving water; 3. The gate water blocking process can be operated in stages, that is, first the flip door structure is pulled horizontally to the bottom of the river, and this process can be carried out slowly to ensure the stability and controllability of the opening and closing process. When the upper flap gate structure is pulled horizontally to the center of the river channel, there is still a large flow space on the upper part, so it does not affect the normal flow of the river channel. At this time, the gate is in standby status. When the water-blocking function needs to be activated, the upper flap gate structure is activated. This process only takes about 15 minutes to complete, and rapid opening and closing can be achieved; 4. Construction and operation and maintenance are all carried out on shore, which does not affect the navigation of the river. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0029] See also Figures 1 to 5 The structure of a horizontally pulled upward-flipping gate water gate shown in the figure comprises a gate structure 100, an upward-flipping door structure 200, a gate gate 300 and a water gate bottom sill 400.

[0030] The gate and garage structures 100 are arranged on both sides of the central river channel. In this embodiment, there are two gate and garage structures 200, and the two gate and garage structures 200 are arranged on both sides.

[0031] The upper flip door structure 200 is movably arranged inside the gate and warehouse structure 100 and is used to block water. The horizontal pulling movement of the upper flip door structure 200 in this embodiment is controlled by an auxiliary device (not shown in the figure). When the upper flip door structure 200 needs to block water, the upper flip door structure 100 is pulled horizontally by the auxiliary device to be located at the bottom sill 400 of the sluice and in the center of the river channel. On the contrary, when it is not blocking water, the upper flip door structure 100 is returned to the gate and warehouse street located on both sides through the auxiliary device crossbeam 100. Specifically, the length of the upper flip door structure 200 is the same as the length of the gate and warehouse structure 100. It is also possible to flexibly adjust the length of the gate and warehouse structure 100 and the upper flip door structure 200 according to the land conditions on both sides, so that the land occupation of the two sides is different. When there is no land condition on one side and the land condition on the other side is better, the gate and warehouse structure 100 and the upper flip door structure 200 can also be set only on one side.

[0032] The gate gate 300 is movably arranged on the gate structure 100 and is located between the gate structure 100 and the center of the river channel and is used to isolate the water flow of the river channel, thereby providing a dry operation and maintenance environment inside the gate structure 100, and also facilitating the maintenance and daily maintenance of the flip door structure 200. The opening and closing of the gate gate 300 in this embodiment is controlled by an auxiliary device (not shown in the figure).

[0033] The sluice sill 400 is arranged in the center of the river channel and cooperates with the upward-flipping door structure 200 .

[0034] The upward-flipping door structure 200 includes a steel shell base 210 arranged on the door storage structure 100, an upward-flipping door body 220 movably arranged on the steel shell base 210 and used for flipping up to block water, and a roller 230 slidably configured at the bottom of the steel shell base 210 and slidingly cooperating with the door storage structure 100. The upward-flipping door structure 200 in this embodiment also includes a base anti-slip key 240 arranged at the bottom of the steel shell base 210 and used to prevent the upward-flipping door structure 200 from deviating to both sides as a whole.

[0035] The steel shell base 210 is provided with a ballast water tank (not shown in the figure) that can be filled and drained. The upper flip door body 220 adopts a steel shell empty box structure. The upper flip door body 220 is movably connected to the steel shell base 210 through a hinge structure. The upper flip door body 220 is provided with a filling and exhaust pipe 221 for turning the upper flip door body 220 upward. The steel shell base 210 in this embodiment is provided with a ballast water tank inside the steel shell base 210, which has the function of filling and draining water. When the upper flip door structure 200 is in the horizontal pulling process, in order to avoid the upper flip door structure 200 being too heavy and causing the closing force required to be too large and the difficulty in opening and closing, the steel shell base 210 can drain water inside to reduce its deadweight, but it is necessary to ensure that the overall deadweight of the upper flip door structure 200 is slightly greater than the buoyancy to avoid the upper flip door structure floating. When the upper flip door structure 200 reaches the center of the river channel and is ready to block water, water can be filled inside the steel shell base 210 to increase the deadweight of the upper flip door structure 200, thereby ensuring the stability of water blocking.

[0036] The door garage structure 100 includes a door garage 110 and a door garage bottom plate 120. The door garage 110 adopts a reinforced concrete dock structure. The foundation of the door garage 110 is provided with a pile foundation 111. The door garage bottom plate 120 is provided with a roller track 121 that cooperates with a roller 230. In this embodiment, a limit stopper 130 that cooperates with a base anti-slip key 240 is provided on the inner side of the door garage 110. Specifically, the two reinforced concrete roller tracks 121 on the door base plate 120 have a top elevation higher than the surface elevation of the door base plate 120, thereby facilitating the staff to enter the bottom of the upper door structure 200 to inspect the rollers 230, and a plurality of limit blocks 130 are arranged on both sides of the door base 110. The limit blocks 130 are not arranged throughout the entire length, but are arranged at intervals at a certain distance, and are mainly used to prevent the upper door structure 200 from deviating to both sides when it is pulled horizontally. When the upper door structure 200 is pulled horizontally, there is water inside the door base 110, and the water level is higher than the top elevation of the upper door structure 220, that is, the upper door structure 200 is completely submerged in water. At this time, the upper door structure 200 may deviate to both sides during the horizontal pulling process. When the upper door structure 200 tends to deviate to both sides, the base anti-slip key 240 located at the bottom of the upper door structure 200 contacts the limit block 130 to prevent it from further deviating.

[0037] The sill 400 of the sluice gate adopts a reinforced concrete hollow box structure, and the upper surface of the sill 400 is provided with a sluice gate track 410 that cooperates with the roller 230. The top elevation of the sluice gate track 410 in this embodiment is higher than the top elevation of the sill 400 of the sluice gate. When siltation occurs, since the sluice gate track 410 is relatively high, generally small siltation does not affect the sluice gate track 410. When the siltation exceeds the top elevation of the sluice gate track 410, the riverbed needs to be dredged.

[0038] Anti-slip teeth sills 420 cooperating with the base anti-slip keys 240 are provided on both sides of the top of the sluice sill 400. The anti-slip teeth sills 420 in this embodiment have two functions: first, during the horizontal pulling process of the upper flip door structure 200, they can be used as a limit device to prevent the upper flip door structure 200 from deviating to both sides during the horizontal pulling process; second, during the water blocking process of the upper flip door structure 200, the water pressure generated by the water head difference is transmitted to the anti-slip teeth sill 420 through the base anti-slip keys 240 at the bottom of the upper flip door structure 200, and then transmitted to the entire sluice sill 400 by the anti-slip teeth sill 420.

[0039] Stone-blocking grilles 430 for intercepting riverbed stones or garbage are also provided on both sides of the top of the sluice sill 400, and the stone-blocking grilles 430 are arranged outside the anti-slip tooth sill 420. The stone-blocking grilles 430 can allow water to pass through, but can intercept riverbed stones and garbage.

[0040] Anti-seepage steel plate columns 440 are arranged on both sides of the sluice sill 400 , and large stones 450 are backfilled on the outer sides of the anti-seepage steel plate columns 400 .

[0041] The working principle of the present invention is as follows:

[0042] First, adjust the amount of water in the ballast water tank of the steel shell base 210 so that the self-weight of the up-flip door structure 200 is slightly greater than its buoyancy to facilitate its horizontal pulling. Open the gate 300 to allow the river water to enter the gate 110. At this time, the up-flip door structure 200 is completely submerged. Pull the up-flip door structure 200 horizontally to the center of the river. During this process, the up-flip door structure 200 is submerged in the river bottom. The up-flip door structure 200 is submerged in the river bottom during the horizontal pulling process, which has the following advantages: First, it is basically not affected by waves, typhoons, etc. on the water surface. The horizontal pulling process is safer and more controllable than the traditional horizontal sliding door with the top of the conventional door exposed above the water surface. Second, the water blocking area is small during the horizontal pulling process, and the top surface of the upper flip door structure 200 retains a large water flow area, which avoids the door body vibration caused by the sharp increase in the river flow rate due to the narrowing of the river flow area during the horizontal pulling process. Therefore, the present invention solves the problem that the traditional horizontal sliding door has too much water blocking during the opening and closing process and cannot be opened and closed with moving water. When the upper flip door structure 200 reaches the water blocking position, water is filled in the ballast water tank of the steel shell base 210 to increase the overall deadweight, the door warehouse gate 300 is closed, and the upper flip door structure 200 is started. The upper flip door structure 200 adopts Pneumatic type, that is, the upper flip door body 220 adopts a steel shell hollow box structure, and an inflation and exhaust pipe 221 is arranged inside. When the upper flip door body 220 is filled with water, the upper flip door body 220 lies underwater. When the upper flip door body 220 is inflated, the water inside the upper flip door body 220 is discharged, and the upper flip door body 220 floats up to block water under the buoyancy of the external water level. The pneumatic upper flip door currently has successful application cases, and other mature upper flip door structures such as bottom shaft drive and hydraulic rod push can also be used to float and realize the water blocking function.
