Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a self-propelled flap gate combined water retaining structure. Background Art

[0002] In water conservancy projects, gates can be opened and closed by operating equipment to drive the movable gate body, thereby achieving the purpose of water discharge and water blocking. They are key equipment that can ultimately achieve the predetermined functions of the project construction.

[0003] Conventional gates are usually integral, and their width is equivalent to the river channel that needs to be blocked. When the river channel is wide and it is impossible to build a pier in the middle of the river channel due to navigation and other reasons, the width of the conventional gate needs to be made very wide, which not only increases the cost, but also brings difficulties to manufacturing, installation, operation, and maintenance. In order to solve the problem that "when the river channel is wide and it is impossible to build a pier in the middle of the river channel, the width of the conventional gate is wide", multiple flap gates that can rotate and rise around the bottom hinge are often combined to achieve the purpose of blocking water.

[0004] However, since the bottom hinge of the flap gate is fixedly installed on the civil engineering bottom plate at the bottom of the river channel, the flap gate and the equipment that operates its opening and closing (usually a hydraulic cylinder) are submerged underwater for a long time, making it difficult to inspect and maintain. As a result, the life span is short and the failure rate is also high. Utility Model Content

[0036] See also Figures 1 to 3 The present embodiment provides a self-propelled flap gate combined water retaining structure, comprising a civil construction base plate 1, a maintenance building 2 and a flap gate module 3. The civil construction base plate 1 is arranged at the bottom of the river channel in a state where the extension direction is perpendicular to the direction of the river flow, and the extension length of the civil construction base plate 1 is the same as the width of the river channel. The maintenance building 2 is covered at one end or both ends of the civil construction base plate 1 and is connected to the river channel. The internal space of the maintenance building 2 can accommodate at least one flap gate module 3, and the internal space of the maintenance building 2 is provided with a lifting device 201 for auxiliary maintenance at a position above the water surface and the ground. Multiple flap gate modules 3 are arranged in sequence on the civil construction base plate 1 and block the river flow, and each flap gate module 3 can move along the civil construction base plate 1 into the maintenance building 2.

[0037] The self-propelled flap gate combined water retaining structure of the present embodiment is applicable to occasions where the river channel width is large and it is impossible to build a pier in the middle of the river channel. In actual use scenarios, water retaining is achieved through the combination of multiple flap gate modules 3, which overcomes the problems of high cost, difficulty in manufacturing and installation, and inconvenient operation of conventional integral gates. When the flap gate module 3 needs to be repaired due to being submerged underwater for a long time, it can be moved along the civil engineering bottom plate 1 into the maintenance building 2, and then the flap gate module 3 to be repaired can be lifted above the water surface for inspection and maintenance with the help of the lifting equipment 201 in the maintenance building 2, which overcomes the problem of inconvenient inspection and maintenance of conventional flap gates.

[0038] It should be noted that, when the flap gate module 3 is to be repaired, multiple flap gate modules 3 need to be moved into the maintenance building 2 in turn and lifted out of the water surface for maintenance by the lifting equipment 201. Therefore, if the width of the on-site river channel permits, it is preferred to set up maintenance buildings 2 at both ends of the civil engineering base plate 1 to improve the maintenance efficiency.

The setting of the slide plates 4 can resist the horizontal water pressure acting on the flap gate module 3 on the one hand, and can also prevent the flap gate module 3 from deflecting during the movement along the civil engineering bottom plate 1 on the other hand.

[0040] Preferably, in this embodiment, the slide plate 4 is made of a material with a low friction coefficient, and the low friction property of the material reduces the friction between the slide plate 4 and the civil engineering base plate 1, so that the flap gate module 3 moves along the civil engineering base plate 1 more smoothly.

[0041] Preferably, see Figure 3 and Figure 4 Two gate running tracks 5 are arranged in parallel and spaced on the upstream and downstream sides of the civil engineering bottom plate 1, and the two opposite side walls of the rectangular groove 101 are concave to form two track installation grooves 102. The two gate running tracks 5 are arranged in the two track installation grooves 102 one by one, and two running devices 301 are arranged on the opposite sides of the flap gate module 3. The two running devices 301 are pressed on the two gate running tracks 5 one by one, and the running devices 301 can move along the extension direction of the gate running tracks 5. The gate running tracks 5 are arranged in the track installation grooves 102 to prevent the flap gate module 3 from overturning under the action of water pressure.

[0042] Preferably, the running device 301 includes a roller assembly and a driving device, the roller assembly is arranged on the gate running track 5 in a rolling manner along the extension direction of the gate running track 5, and the driving end of the driving device is connected to the driving wheel on the roller assembly. Under the drive of the driving device, the roller assembly rolls and drives the flap gate module 3 to move along the gate running track 5.

The lifting device 201 is set above both the water surface and the ground, and the pool 202 is connected to the river. Each flap gate module 3 can move along the gate walking track 5 to the maintenance workshop 2. At this time, the flap gate module 3 is located in the lower pool 202 as a whole, and then the flap gate module 3 is hooked and lifted by the lifting device 201 above, and finally repaired and maintained above the water surface.

One end of the flap gate body 302 is hinged at the top of the cabin 304, and one end of the linear drive device 303 is hinged at the top of the cabin 304, and the other end is hinged at the bottom of the flap gate body 302. When the flap gate module 3 is working, the linear drive device 303 pushes the flap gate body 302 to rotate around the hinge point with the cabin 304, thereby achieving the purpose of rotating and lifting the flap gate body 302 to block water, and rotating and lowering the flap gate body 302 to lie flat to discharge water.

[0048] Preferably, in this embodiment, the linear drive device 303 adopts a hydraulic cylinder.

[0049] Preferably, the flap door body 302 is a hollow box, and a reinforcing plate is arranged at the internal interval of the flap door body 302. Since the flap door body 302 does not completely block the water flow when it is in the water blocking state, some water still flows under the flap door body 302.

[0051] Preferably, signal acquisition equipment, electrical control equipment and communication equipment are provided in the cabin 304. The signal acquisition equipment and the electrical control equipment are both connected to the linear drive device 303 by signal, and the communication equipment is connected to the electrical control equipment by signal, so that the position and operation status information of the flap gate module 3 can be collected and reported, and external instructions can be executed and the execution results can be fed back.

[0052] It should be noted that the signal acquisition equipment, electrical control equipment and communication equipment are all existing mature technologies, and the specific application forms will not be repeated here.

[0053] Preferably, a leakage drainage pump and a drainage pipe are provided in the cabin 304, one end of the drainage pipe is connected to the drainage port of the leakage drainage pump, and the other end is connected to the outside of the cabin 304.

[0054] Preferably, in the present embodiment, each flap gate module 3 uses an independent lithium battery pack to power the linear drive device 303, the running device 301 and other various electrical equipment.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
