Description

Technical Field

[0001] This utility model relates to the field of water conservancy equipment technology, and in particular to a novel locking mechanism for improving the safety of dam gates. Background Technology

[0002] Hydropower gates are important devices used to control water flow and regulate water levels, and are widely used in water conservancy projects such as hydropower stations, reservoirs, and rivers.

[0003] In Chinese utility model patents, such as CN221276541U, a high-sealing dam gate is disclosed. The gate body's sealing performance is greatly improved by the cooperation of two first and second sealing strips, thereby enhancing its water-blocking efficiency. Furthermore, the first and second reinforcing plates of the copper hot pot can provide auxiliary support for the gate body, preventing it from being deformed due to excessive water impact, thus greatly improving the gate body's working efficiency and service life.

[0004] In the above-mentioned technology, the first fixing plate can only contact the ground and form a stable triangle with the gate body through the second fixing plate when the gate is closed, reducing the possible damage to the gate body. However, when the gate body is opened and leaves the ground, the first fixing plate cannot contact the ground, which means that it cannot continue to provide auxiliary support for the gate body. In addition, the impact force that the gate bears when it is not fully open is usually much greater than the impact force when the gate is fully closed. As a result, the gate that is detached from the auxiliary support is prone to deformation. Moreover, compared with the gate with screw lifting, the impact force that the gate bears when it is in a semi-open state is prone to cause fatigue damage to the screw threads, which in turn leads to problems such as gate instability. In view of this, this application proposes a new locking mechanism to improve the safety of dam gates. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel locking mechanism to improve the safety of dam gates.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel locking mechanism for improving the safety of dam gates includes two walls, with a mounting frame installed between them. A gate body is slidably connected within the mounting frame. A top plate is installed on the top surface of the mounting frame, and a threaded rod is fixedly installed on the top surface of the gate body. A moving mechanism is installed on the top surface of the top plate, and the moving mechanism drives the threaded rod to slide axially. A guide rail is fixedly installed on the side of each wall, and a sliding block is slidably connected within each guide rail. Multiple support rods are symmetrically installed on the outer side of each sliding block. Two mounting plates are symmetrically installed on the outer side of the gate body, and the other end of each support rod is fixedly connected to the outer side of the corresponding mounting plate. An auxiliary limiting mechanism is installed on the outer side of each sliding block, and the auxiliary limiting mechanism helps to restrict and fix the position of the gate body.

[0008] Preferably, each of the auxiliary limiting mechanisms includes a T-shaped block, and each T-shaped block is fixedly installed on the outside of the corresponding sliding block. Each side of the wall is fixedly installed with a wear-resistant plate. Multiple first hydraulic struts are symmetrically installed on the outside of each T-shaped block, and a pressure plate is installed at the other end of each first hydraulic strut. Each pressure plate abuts against the side of the corresponding wear-resistant plate.

[0009] Preferably, a bottom sealing strip is installed on the bottom surface of the gate body, and a plurality of second hydraulic struts are symmetrically installed on the outer side of the gate body. The other end of the plurality of second hydraulic struts located on the same side is jointly installed with a push plate, and a side sealing strip is installed on the outer side of each push plate, and each side sealing strip abuts against the inner side of the corresponding mounting frame.

[0010] Preferably, the moving mechanism includes a threaded seat, which is rotatably connected to the top surface of the top plate, and the threaded rod is threadedly connected to the threaded seat. A toothed ring is installed on the outer side of the threaded seat. A protective shell is fixedly installed on the top surface of the top plate. A drive motor is installed on the top surface of the protective shell. A drive gear is installed on the outer side of the bottom output shaft of the drive motor, and the drive gear meshes with the toothed ring. Both the drive gear and the toothed ring are located inside the protective shell.

[0011] Preferably, multiple reinforcing right-angle plates are installed between the outer side of each guide rail and the corresponding side of the wall, and the multiple reinforcing right-angle plates are equidistantly arranged along the height direction of the wall.

[0012] Preferably, each of the sliding blocks has a groove on its outer side, and each T-shaped block is slidably connected to the corresponding groove. The drive motor is a conical rotor motor.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model achieves full synchronous support during the lifting and lowering process of the gate body and in the incomplete opening and closing state through devices such as sliding blocks, guide rails, and support rods. The sliding blocks slide synchronously with the gate body along the guide rails, and the support rods connect the sliding blocks to the mounting plate of the gate body, transmitting the force of the gate to the wall. This solves the limitation of the existing structure that can only support when the gate is closed, and provides stable mechanical support for the dynamic operation of the gate.

[0015] 2. This utility model achieves precise locking and limiting of the gate at any position through devices such as the first hydraulic support rod, pressure plate, wear-resistant plate, T-block, and moving mechanism, and reduces damage to the screw thread. After the moving mechanism drives the gate to the target position, the self-locking property of the conical motor in the moving mechanism locks the screw rod. The first hydraulic support rod on the T-block pushes the pressure plate to press against the wear-resistant plate, thereby sharing the pressure impact force and the gate's own weight with the screw rod, thus extending the service life of the screw rod.

[0016] 3. This utility model strengthens the support strength of the sliding block and disperses the force by strengthening the right-angle plate and other devices. The right-angle plate connects the sliding block and the wall at equal intervals to build a stable triangular support structure, which evenly disperses the water pressure and impact force transmitted from the gate to the sliding block to the wall, avoiding the sliding block from breaking or deforming due to concentrated force, and further improving the reliability of the support system.

[0023] 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.

[0024] This utility model provides a technical solution: such as Figure 1-5 As shown, a novel locking mechanism for improving the safety of dam gates includes two walls 1, with an installation frame 2 installed between the two walls 1. A gate body 3 is slidably connected within the installation frame 2. A top plate 5 is installed on the top surface of the installation frame 2. A threaded rod 4 is fixedly installed on the top surface of the gate body 3. A moving mechanism is installed on the top surface of the top plate 5, and the moving mechanism drives the threaded rod 4 to slide axially. A guide rail 6 is fixedly installed on the side of each wall 1. A sliding block 7 is slidably connected within each guide rail 6. Multiple support rods 8 are symmetrically installed on the outer side of each sliding block 7. Two installation plates 9 are symmetrically installed on the outer side of the gate body 3, and the other end of each support rod 8 is fixedly connected to the outer side of the corresponding installation plate 9. An auxiliary limiting mechanism is installed on the outer side of each sliding block 7, and the auxiliary limiting mechanism helps to limit the position of the gate body 3.

[0025] It should be noted that the exposed threaded rod 4 is a characteristic of the open-rod gate. The axial sliding of the threaded rod 4 makes it easy to see the movement position of the gate. Furthermore, through the guide rail 6, sliding block 7, and support rod 8, when the gate body 3 is sliding or in the open state, the impact of the water flow on the gate body 3 can be transmitted to the guide rail 6 through the support rod 8, thereby achieving stable support for the gate body 3 and ensuring that the gate body 3 can deform.

[0026] Furthermore, each auxiliary limiting mechanism includes a T-shaped block 12, and each T-shaped block 12 is fixedly installed on the outside of the corresponding sliding block 7. Each side of the wall 1 is fixedly installed with a wear-resistant plate 15. Multiple first hydraulic struts 13 are symmetrically installed on the outside of each T-shaped block 12, and a pressure plate 14 is installed on the other end of each first hydraulic strut 13. Each pressure plate 14 abuts against the side of the corresponding wear-resistant plate 15.

[0027] It should be noted that the hydraulic strut is a hydraulic actuator that integrates support and fixation. The first hydraulic strut 13 can push the pressure plate 14 to squeeze the wear-resistant plate 15, and the friction force can share the weight of the gate body 3 and the downward impact force, thereby reducing the thread damage to the threaded rod 4. Furthermore, the flow of a single oil source can be evenly or proportionally distributed among multiple hydraulic struts that need to extend and retract synchronously as needed through the flow divider valve, thereby ensuring that each strut maintains a synchronous speed.

[0028] Furthermore, a bottom sealing strip 19 is installed on the bottom surface of the gate body 3, and multiple second hydraulic struts 16 are symmetrically installed on the outer side of the gate body 3. The other end of the multiple second hydraulic struts 16 located on the same side is also equipped with a push plate 17. A side sealing strip 18 is installed on the outer side of each push plate 17, and each side sealing strip 18 abuts against the inner side of the corresponding mounting frame 2.

[0029] Furthermore, the moving mechanism includes a threaded seat 20, which is rotatably connected to the top surface of the top plate 5, and the threaded rod 4 is threadedly connected to the threaded seat 20. A toothed ring 21 is installed on the outer side of the threaded seat 20. A protective shell 23 is fixedly installed on the top surface of the top plate 5. A drive motor 24 is installed on the top surface of the protective shell 23. A drive gear 22 is installed on the outer side of the output shaft on the bottom surface of the drive motor 24. The drive gear 22 meshes with the toothed ring 21, and both the drive gear 22 and the toothed ring 21 are located inside the protective shell 23.

[0030] Since the gate body 3 is limited by the mounting frame 2, it cannot rotate. Therefore, the threaded rod 4 can be axially slid by rotating the threaded seat 20.

[0031] Furthermore, multiple reinforcing right-angle plates 10 are installed between the outer side of each guide rail 6 and the corresponding side of the wall 1, and the multiple reinforcing right-angle plates 10 are equidistantly arranged along the height direction of the wall 1 to reinforce and support the side of the guide rail 6, thereby ensuring the support effect on the gate body 3.

[0032] Furthermore, each sliding block 7 has a sliding groove 11 on its outer side, and each T-shaped block 12 is slidably connected to the corresponding sliding groove 11. The drive motor 24 adopts a conical rotor motor, and its output shaft can be locked after power failure, thereby ensuring the static stability of the gate body 3.

[0033] This utility model provides a novel locking mechanism to improve the safety of dam gates. The specific working principle is as follows:

[0034] When the gate needs to be opened, the drive motor 24 starts, and its output shaft drives the drive gear 22 to rotate. The drive gear 22 meshes with the gear ring 21, thereby driving the threaded seat 20 to rotate.

[0035] Since the gate body 3 is limited by the mounting frame 2 and cannot rotate, the rotation of the threaded seat 20 is converted into the axial upward movement of the threaded rod 4, which drives the gate body 3 to rise synchronously. During this process, the gate body 3 pulls the support rod 8 through the mounting plate 9, so that the sliding block 7 slides upward synchronously along the guide rail 6. The guide rail 6 is firmly connected to the wall 1 through the reinforcing right angle plate 10, providing lateral support for the gate body 3 and offsetting the lateral force generated by the water flow impact.

[0036] When the gate is opened to the designated position, the drive motor 24 is de-energized. Its conical rotor structure causes the output shaft to lock, initially fixing the position of the gate body 3. At the same time, the auxiliary limit mechanism is activated, the first hydraulic support rod 13 extends, pushes the pressure plate 14 to tightly squeeze the wear-resistant plate 15, and uses friction to lock the sliding block 7 on the guide rail 6, further sharing the weight of the gate body 3 and the impact force of the water flow, and avoiding thread wear caused by the threaded rod 4 being subjected to force alone.

[0037] If the gate needs to be closed, first control the first hydraulic strut 13 to retract, release the lock of the sliding block 7, and then start the drive motor 24 to reverse, so that the threaded rod 4 drives the gate body 3 to descend.

[0038] After the gate is closed, the second hydraulic strut 16 extends and pushes the push plate 17 to make the side sealing strip 18 fit tightly with the mounting frame 2, and together with the bottom sealing strip 19, achieves all-round sealing. At the same time, the first hydraulic strut 13 is locked again to ensure the stability of the gate in the closed state.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
