Description

Technical Field

[0001] This utility model belongs to the technical field of gate equipment, and in particular relates to a floating box type stacked beam maintenance steel gate. Background Technology

[0002] Floating box gates can be used as working gates in docks, as well as maintenance gates on locks, spillways, and sluices. They primarily rely on buoyancy for movement, and the gate leaf structure contains enclosed spaces. Their key features include: the ability to float up and down in the water due to its own buoyancy; and the ability to close relatively wide water openings with large-span gates. Floating box stacked beam gates combine the advantages of both floating box gates and stacked beam gates: they are buoyant, facilitating hooking and unhooking within the gate slot and above the water surface; they can close large-span openings; and the gate leaf sections are interchangeable. Floating box stacked beam gates are designed with multiple stacked beams, resulting in lighter weight per section and reduced gate height, facilitating manufacturing, transportation, installation, and dismantling. Temporary lifting equipment is used for opening and closing the gate when it floats above the water, saving on project investment.

[0003] Maintenance gates are generally located upstream of working gates and are used for short-term water blocking during the maintenance of structures or working gates. They are typically opened and closed in still water. Emergency gates are often located upstream of deep-hole working gates and are used to close in flowing water and open in still water in the event of an accident involving a structure or equipment. When they also serve as maintenance gates, they are called emergency maintenance gates. Emergency maintenance gates that need to be closed urgently within a limited time are called rapid maintenance gates. Utility Model Content

[0004] The purpose of this utility model is to provide a floating box-type stacked beam maintenance steel gate, and to provide a floating box-type stacked beam gate section, which saves costs by using stacked beams.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] The floating box type stacked beam maintenance steel gate includes a main box section with a rectangular cross-section, and auxiliary box sections symmetrically arranged on both sides of the main box section. The auxiliary box sections have a trapezoidal cross-section. Column sleeves are fixed on the sides of the auxiliary box sections for connecting to guide columns set in the gate slot. Pumping holes are opened on the upper side of each auxiliary box section.

[0007] The main box section includes front and rear panels that form the gate water surface. The front and rear panels are arranged parallel to each other, and web plates are fixed on the upper and lower sides to form a cavity inside. A water inlet hole is opened on one side panel to connect to the cavity. A sealing plug is installed in the cavity corresponding to the position of the water inlet hole. A screw is vertically fixed in the center of the sealing plug. The other end of the screw passes through the other side panel and is provided with a driving component to drive the sealing plug to close or open the water inlet hole.

[0008] Furthermore, a partition is connected between the front and rear panels of the main box section to divide the abdominal cavity into upper and lower layers. The panel is also equipped with multiple ribs, which are equidistantly arranged from one side of the main box section to the other side.

[0009] Furthermore, a sealing sleeve is fixed to the position of the water inlet hole into the abdominal cavity, the sealing plug is a cylindrical structure and is fitted onto the sealing sleeve, and a rubber sleeve is fitted onto the side wall of the sealing plug.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1-4 As shown: The floating box type stacked beam maintenance steel gate includes a main box section with a rectangular cross-section. Auxiliary box sections are symmetrically arranged on both sides of the main box section. The auxiliary box section 3 has a trapezoidal cross-section, which is an isosceles trapezoidal structure, making the side of the gate narrow. The side of the auxiliary box section 3 is fixed with a column sleeve 32 for fitting into the guide column 51 set in the gate slot 5. Each auxiliary box section 3 has a pumping hole 31 on its upper side. There are two column sleeves corresponding to each auxiliary box section on each side, which are evenly arranged vertically. The main box section and the auxiliary box section are interconnected. By pumping water from the auxiliary box section, the entire interior of the gate is in a cavity state.

[0021] The main box section includes front and rear panels 1 that form the gate water surface. The front and rear panels 1 are arranged parallel to each other, and the upper and lower sides are fixed with web plates 2, forming a cavity inside. A water inlet hole is opened on one side panel 1 to connect to the cavity. A sealing plug 4 is installed in the cavity corresponding to the position of the water inlet hole. A screw 41 is vertically fixed in the center of the sealing plug 4. The other end of the screw 41 passes through the other side panel and is provided with a driving component 42 to drive the sealing plug 4 to close or open the water inlet hole.

[0022] This utility model steel gate is a stacked beam type installation gate with multiple box sections arranged vertically. When the gate is opened, the water inlet is closed by driving the sealing plug. Then, the water stored in the gate box cavity is pumped out from the water outlet at the upper edge of the gate by the water pump, which reduces the overall weight of the gate. The gate box floats up under the action of buoyancy to open the gate, or the gate section can be lifted by the hoist with a very small lifting force.

[0023] like Figure 2 As shown: A partition 11 connects the front and rear panels 1 of the main box section, dividing the abdominal cavity into upper and lower layers. The panel 1 also has multiple ribs 12 arranged at equal intervals from one side of the main box section to the other. The partition and ribs are used to enhance the strength of the panel and prevent the panel from deforming under pressure.

[0024] A sealing sleeve 13 is fixed to the water inlet hole into the abdominal cavity. The sealing plug 4 is a cylindrical structure that fits onto the sealing sleeve 13. A rubber sleeve 43 is fitted onto the side wall of the sealing plug 4. This is used to improve the sealing performance of the water inlet hole.

[0025] The driving component 42 has a disc-shaped structure, with its end face fixed to the end of the screw 41. The side wall of the driving component 42 has an insertion hole 44 for inserting and driving the screw rod. The panel 1 has a threaded sleeve that fits onto the screw rod 41. A rod such as a steel bar is inserted into the insertion hole of the driving component, and then the screw rod is rotated. The threaded engagement with the threaded sleeve drives the sealing plug to move, opening the water inlet.

[0026] A support plate 33 is installed on the side of the auxiliary box section 3, and a rubber pad 34 is installed on the support plate to cooperate with the gate slot 5 to improve the sealing performance.

[0027] like Figure 3 As shown: Grooves 21 are provided on the sides of the web plate 2, and rubber rings 22 are installed in the grooves 21. These are used to improve the sealing between the floating box sections after the beams are stacked on top of each other.

[0028] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
