[0045] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0046] In the prior art, under wind load conditions, when the flat lifting gate 10 is opened and closed, the steel wire rope is flexible and there will be a certain degree of lateral displacement, which makes it difficult for the gate 10 to enter the groove. Especially for the tide gate 10 with higher safety requirements, the gate 10 must be closed in windy conditions to block the tide and protect the safety of the city on the river side.
[0047] like Figure 1 , Figure 2 As shown, the gate 10 auxiliary slot-entry device provided in this embodiment is used to guide the gate 10 into the gate slot 20. It can be an energy-saving self-balancing auxiliary gate 10 slot-entry device under wind load conditions. The gate 10 auxiliary slot-entry device specifically includes: a guide member 100 and a fixed hinge support 200.
[0048] The guide member 100 is rotatably connected to the fixed hinge support 200. The connection method between the guide member 100 and the fixed hinge support 200 is specifically hinged. The guide member 100 and the fixed hinge support 200 are connected by a rotating shaft, so that the guide member 100 can rotate around the rotating shaft, thereby realizing the rotation of the guide member 100 relative to the fixed hinge support 200.
[0049] The bottom of the fixed hinge support 200 is fixed to the shore 30 , and the fixed hinge support 200 is located near the opening of the gate slot 20 . The fixed hinge support 200 provides the guide member 100 with steering freedom on the one hand, and can guide the gate 10 on the other hand.
[0050] The guide member 100 has a supporting edge 111 and a pushing edge 121. The supporting edge 111 is used to support the gate 10. When the bottom of the gate 10 is pressed on the supporting edge 111, the guide member 100 rotates around the fixed hinge support 200. When the guide member 100 rotates, the pushing edge 121 pushes the gate 10 to move in the direction of extending into the door slot 20, thereby guiding the gate 10 into the door slot 20, so as to close the gate 10 under wind load.
[0051] It should be noted that the sizes of the guide member 100 and the fixed hinge support 200 can be adapted to the size of the gate 10 , ensuring that the sizes of the guide member 100 and the fixed hinge support 200 can guide the gate 10 into the door groove 20 .
[0052] The auxiliary slot-entry device for the gate 10 provided in the present embodiment can cause the gate 10 to deviate under wind load, and the gate 10 will fall on the support plate of the guide member 100. Under the deadweight of the gate 10, the guide member 100 is driven to rotate around the fixed hinge support 200. During the rotation of the guide member 100, the pushing edge 121 pushes the side of the gate 10, pushing the gate 10 toward the gate slot 20, so that the gate 10 can be guided into the gate slot 20, closing the gate 10, blocking the tide, and protecting the safety of the city on the river side. This alleviates the technical problem in the prior art that the plane lifting gate 10 will be displaced in a directional manner under wind load, resulting in difficulty in the gate 10 entering the slot.
[0053] On the basis of the above embodiments, in an optional embodiment, the guide member 100 in the auxiliary slot entry device of the gate 10 provided in this embodiment includes a transverse plate 110 and a vertical plate 120; the transverse plate 110 and the vertical plate 120 are connected to each other, and the transverse plate 110 and the vertical plate 120 are arranged at an angle; a supporting edge 111 is formed at the top of the transverse plate 110; and a pushing edge 121 is formed on the side of the vertical plate 120 facing the gate slot 20.
[0054] Specifically, the vertical plate 120 and the horizontal plate 110 are an integrally formed structure. When the guide member 100 is not in contact with the gate 10, that is, in the initial position, the vertical plate 120 is relatively located in a vertical position, and the horizontal plate 110 is relatively located in a horizontal position.
[0055] When the gate 10 contacts the transverse plate 110, the gravity of the gate 10 acts on the transverse plate 110, and the transverse plate 110 is forced to rotate downward. Since the vertical plate 120 and the transverse plate 110 are an integrated structure, the vertical plate 120 and the transverse plate 110 rotate downward together, and the vertical plate 120 contacts the side of the gate 10. The vertical plate 120 pushes the gate 10 to move in the direction of the door slot 20, and guides the gate 10 into the door slot 20.
[0056] Preferably, the vertical plate 120 and the transverse plate 110 are arranged in an L shape, that is, the vertical plate 120 and the transverse plate 110 are arranged perpendicular to each other. When the transverse plate 110 rotates downward under the pressure of the gate 10, the vertical plate 120 can act on the side of the gate 10 to guide the gate 10 toward the door slot 20.
[0057] In an optional embodiment, the auxiliary slot entry device of the gate 10 further includes a roller 300 ; the roller 300 is disposed on the vertical plate 120 , and the roller 300 is rotatably connected to the vertical plate 120 ; the roller 300 is configured to be able to roll in contact with the side of the gate 10 .
[0058] Specifically, the roller 300 is rotatably connected to the vertical plate 120 via a rotating shaft. The roller 300 can rotate around the rotating shaft itself. The setting of the roller 300 achieves rolling contact with the gate 10, effectively reducing the contact resistance between the vertical plate 120 and the gate 10.
[0059] Preferably, the roller 300 is located at an end of the vertical plate 120 away from the horizontal plate 110 .
[0060] In addition, as needed, a plurality of rollers 300 may be provided on the vertical plate 120 to reduce the resistance of the gate 10 entering the groove.
[0061] In an optional embodiment, the auxiliary slot entry device of the gate 10 also includes a counterweight component 400; the counterweight component 400 is arranged on the side of the guide member 100 away from the gate slot 20, and the counterweight component 400 is used to adjust the center of gravity of the guide member 100 so that the guide member 100 can be reset after the gate 10 enters the slot.
[0062] Specifically, the counterweight component 400 changes the center of gravity of the guide component 100 by its own weight. When the gate 10 enters the slot, the gate 10 separates from the guide component 100. The guide component 100 relies on the eccentric torque and rotates to the initial position relative to the fixed hinge support 200, so that the gate 10 can enter the slot for use next time.
[0063] In an optional embodiment, a guide arc surface 210 is provided on one side of the fixed hinge support 200 close to the door slot 20 , and the guide arc surface 210 is used to guide the gate 10 into the door slot 20 .
[0064] Specifically, the arc curve of the guide arc surface 210 bends toward the slot opening of the door slot 20, so that the guide arc surface 210 can also serve as a guide for the gate 10 to enter the slot in the latter stage of closing the door, reduce the resistance of the gate 10 entering the slot, and guide the door body to enter the slot smoothly.
[0065] In an optional embodiment, a plurality of fixed hinge supports 200 are provided, and the plurality of fixed hinge supports 200 are symmetrically arranged on the banks 30 on both sides of the door slot 20, and each fixed hinge support 200 is rotatably connected to a guide member 100 to achieve auxiliary slot entry under any wind direction.
[0066] In an optional embodiment, the auxiliary slot entry device of the gate 10 also includes a limiting member 500; the limiting member 500 includes an upper limit block 510 and a lower limit block 520; the upper limit block 510 and the lower limit block 520 are both arranged on the fixed hinge support 200, and the upper limit block 510 and the lower limit block 520 are used to limit the rotation range of the guide member 100.
[0067] Specifically, the upper limit block 510 and the lower limit block 520 are fixed on the fixed hinge support 200 one above and one below. When the guide member 100 is reset and swung, the upper end of the guide member 100 can contact the upper limit block 510, and the lower end of the guide member 100 can contact the lower limit block 520, thereby limiting the range of the reset and swing of the guide member 100.
[0068] The gate 10 auxiliary slot entry device provided in this embodiment, the gate 10 is pressed on the horizontal plate 110 when offset, and the vertical plate 120 pushes the gate 10, pushing the gate 10 toward the gate slot 20. After the gate 10 enters the slot, the guide member 100 returns to its original position under the action of the counterweight. This device is safe, reliable, and energy-saving, and does not require any equipment to operate, thereby improving the safe operation of the hub to a certain extent.
[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
