Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a modular steel dam gate plate connecting mechanism. Background Art

[0002] The hydraulic flip steel dam gate is a commonly used device for controlling water flow in water conservancy projects. Its main function is to adjust the water level of the river, control the flow of water, prevent floods and supply water. This type of steel dam gate is mainly composed of gate plates, gate slots, gate seats, gate piers, hydraulic systems and other parts. The gate plates are the core components of the structure. They can be flipped open and closed through the control of the hydraulic system. The gate slots are used to accommodate the gate plates, while the gate seats are the basis for supporting and fixing the gate plates. The gate piers are the columnar structures that support the entire gate body. The hydraulic flip steel dam gates are often arranged in sequence on the same horizontal line and used synchronously. This arrangement can achieve more precise control of the river flow and improve the overall operation efficiency of the water conservancy project. Therefore, two adjacent gate plates need to be connected by a connecting mechanism.

[0003] For example, a modular steel dam gate connection mechanism disclosed in the authorization announcement number CN220183957U includes a concrete base, a steel dam gate installation mechanism is arranged on the top of the concrete base, and the steel dam gate installation mechanism includes a support hinge seat fixedly installed on the top of the concrete base, a semicircular bearing shaft body is fixedly connected to the top of the support hinge seat, a bottom shaft is movably connected to the inner side of the semicircular bearing shaft body, a steel dam gate body is fixedly connected to the top of the bottom shaft, and a connecting block is fixedly connected to the front of the steel dam gate body, and a plurality of steel dam gate bodies are arranged in the support hinge seat by utilizing the connection between the bottom shaft and the semicircular bearing shaft body, and The connection between the two adjacent steel dam gate bodies is maintained firmly by the connecting block and its internal structure. However, this technical solution requires the staff to manually rotate the turntable so that the rotating shaft drives the driving bevel gear to rotate. This manual operation is not only time-consuming and labor-intensive, but also easily causes physical discomfort to the staff. Especially in severe weather conditions, debugging, maintenance and other operations are more difficult. In addition, due to the use of a large number of rotating parts such as gears and shafts, these parts are easily affected by rust and corrosion during long-term use, resulting in their performance degradation or even damage, which increases the difficulty and workload of assembly and maintenance for the staff.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 The utility model provides an embodiment: a modular steel dam gate plate connection mechanism, comprising a base 1 and a connecting arm 2 hingedly installed inside the base 1, a back plate 3 is fixed on the outer wall of the same side of the two connecting arms 2, a hollow docking shell 4 is installed on the outer wall of one side of the back plate 3, and a front gate plate 5 is installed on the outer wall of the hollow docking shell 4 away from the back plate 3, and the top and bottom ends of the front gate plate 5 are both provided with bending parts;

[0020] Hollow grooves 6 and positioning blocks 7 are respectively provided on the outer walls of both sides of the hollow docking shell 4. The hollow grooves 6 and the positioning blocks 7 are plugged into each other to connect two adjacent hollow docking shells 4. The side cross-sectional shape of the hollow grooves 6 and the positioning blocks 7 is "J"-shaped. The "J"-shaped hollow grooves 6 and the positioning blocks 7 are fast and reliable when connected, which can better ensure that the gates can operate normally together under the action of the hydraulic system. Compared with the method of manually rotating the gears, the method of calibrating and connecting using the hollow grooves 6 and the positioning blocks 7 is simpler and more efficient.

[0021] A countersunk hole 701 is provided at the top of the positioning block 7, a support plate 8 is fixed between the back plate 3 and the front gate plate 5 above the hollow groove 6, and an elastic locking structure 9 for positioning the positioning block 7 is installed at the top of the support plate 8;

[0022] The outer walls of both sides of the front gate plate 5 are provided with a lip seam connection structure, which is used to connect two adjacent front gate plates 5. The lip seam connection structure includes a sealing lip 501 fixed on the outer wall of one side of the front gate plate 5, and an inner concave portion 502 provided on the outer wall of the other side of the front gate plate 5;

[0023] When the two front gates 5 are connected, the sealing lip 501 and the inner concave part 502 are plugged in, which effectively reduces the gap amount after the gates are connected, thereby improving the sealing performance of the steel dam gate after connection, reducing the possibility of medium leakage, and is particularly suitable for occasions where the flow of the medium needs to be strictly controlled. The connection method of the sealing lip 501 and the inner concave part 502 can enhance the structural stability of the gate connection, and by reducing the gap amount, the vibration and looseness of the gate connection can be reduced, thereby improving the stability and reliability of the connection components;

[0024] The elastic locking structure 9 includes a hollow cylinder installed at the top of the support plate 8, and a connecting rod slidably installed inside the hollow cylinder. The top of the connecting rod passes through the outside of the hollow cylinder and is installed with a convex disk. The outer peripheral surface of the connecting rod is covered with a spring, and a stopper is installed at the bottom end of the connecting rod. A positioning pin is fixed to the bottom end of the stopper. The bottom end of the positioning pin extends to the inside of the hollow groove 6 and is plugged into the countersunk hole 701. When the positioning block 7 is positioned by the elastic locking structure 9, the staff manually pulls the convex disk, and the convex disk drives the connecting rod and the positioning pin to move up until the positioning pin withdraws to the outside of the hollow docking shell 4. When the hollow groove 6 and the positioning block 7 are connected, the staff releases the convex disk, and the spring causes the connecting rod, the stopper and the positioning pin to move down until the positioning pin is plugged into the countersunk hole 701. This structure can more firmly fix the two adjacent gate plates and avoid the problem of connection failure caused by damage to the gears and the shaft.

[0025] When the embodiment of the present application is in use, the staff first takes out at least two of the steel dam gate plates. At this time, the multiple steel dam gate plates are arranged in sequence on the same horizontal line. Then the staff connects the two adjacent gate plates through the hollow groove 6 and the positioning block 7, so that the two hollow docking shells 4 are preliminarily calibrated and connected. At the same time, the outer walls of the two adjacent front gate plates 5 are assisted by the lip seam connection structure. When the positioning block 7 and the hollow groove 6 are inserted to the limit state, the elastic locking structure 9 locks the countersunk hole 701, so that the two gate plates are completely locked. The connection structure omits various rotating parts such as gears and shafts used in traditional technical solutions, thereby greatly simplifying the connection structure, eliminating the need for frequent lubrication and replacement of wearing parts, reducing the maintenance workload and maintenance costs of personnel, and facilitating the staff to perform the early installation and connection of the gate plates as well as the later maintenance and repair operations.
