This utility model discloses a flood control baffle locking mechanism and its monitoring linkage device, belonging to the field of flood control technology. The locking mechanism mainly includes a fastening bolt, an upper pressure plate, and a side pressure plate. The side pressure plate is provided with first and second wedge-shaped plugs that cooperate with each other, as well as a return spring. The monitoring linkage device mainly includes a monitoring indicator light, a control rod, and a cam. One side of the upper pressure plate has a paddle for actuating the cam. During operation, rotating the fastening bolt clockwise applies a downward movement to the upper pressure plate, which, guided by the first and second wedge-shaped plugs, forms an inward displacement, thereby pressing the side pressure plate inward against the baffle. During the locking process, the upper pressure plate moves the control rod upward according to a preset stroke via the cam, triggering the monitoring indicator light to illuminate, indicating that locking has begun. Afterward, the cam moves the control rod downward, triggering the monitoring indicator light to extinguish, indicating that the locking mechanism has achieved locking.

Description

Technical Field

[0001] This utility model relates to the field of flood control barrier technology, specifically to a flood control barrier locking mechanism and its monitoring and linkage device. Background Technology

[0002] Flood control barriers are crucial infrastructure for protecting against floods in scenarios such as substations, subway entrances, underground parking garage entrances, and flood walls in coastal cities. Flood control barriers need to have reliable locking performance and rapid response capabilities. Conventional flood control barrier locking mechanisms often use direct bolt tightening or simple snap-fit ​​structures, which are prone to uneven stress during the locking process. Furthermore, existing locking mechanisms lack effective status monitoring methods, making it impossible for operators to visually determine whether the locking mechanism has achieved reliable locking, thus affecting the accuracy of flood control work. Utility Model Content

[0003] The purpose of this utility model is to provide a flood control barrier locking mechanism and its monitoring and linkage device, so as to realize the locking of the flood control barrier and indicate the locking status in real time.

[0004] This utility model adopts the following technical solution: a flood control baffle locking mechanism, comprising: The base is fixed above the baffle. Fastening bolts are vertically aligned with the baffle and threaded onto the base; The upper pressure plate is rotatably connected to the lower end of the fastening bolt; Side pressure plates are vertically arranged on the side of the baffle; the upper end of the side pressure plates is vertically opposite to the upper pressure plate. The side pressure plate is fixed with a first wedge plug, and the first wedge plug is mated with a second wedge plug; when the upper pressure plate presses down on the side pressure plate, the second wedge plug pushes the first wedge plug toward the baffle.

[0005] Preferably, a vertical slot is provided on one side of the column, and one side of the baffle is installed in the slot; The base is embedded and fixed at the upper end of the slot; The side pressure plate is installed on one inner wall of the slot, and the second wedge plug is fixed to the inner wall of the slot.

[0006] Preferably, a roller is fixed to the upper end of the side pressure plate; when the upper pressure plate presses down on the side pressure plate, the roller makes rolling contact with the lower side of the upper pressure plate.

[0007] Preferably, multiple sets of the first wedge plug and the second wedge plug are arranged vertically along the side pressure plate.

[0008] Preferably, a positioning block is fixed on the inner wall of the slot, and a vertical slide rod is installed between the positioning block and the side pressure plate. A reset spring that provides an upward pushing force to the side pressure plate is fitted on the slide rod.

[0009] Preferably, a wear-resistant sealing plate is provided between the side pressure plate and the baffle; A side top plate for abutting against the baffle is installed on the inner wall of the slot on the side away from the side pressure plate.

[0010] A flood control barrier locking monitoring and linkage device, characterized in that it includes: Monitoring indicator lights are installed on the base; A control lever, slidably connected below the monitoring indicator light, is used to control the switching of the monitoring indicator light; A cam is rotatably mounted on the lower side of the base and contacts the lower end of the control lever for pushing the control lever; One side of the upper pressure plate has a paddle for actuating the cam.

[0014] This utility model is mainly applicable to the locking and monitoring of flood control barriers at substations, subway entrances, underground parking garage entrances and exits, and flood control walls in coastal cities; its beneficial effects are: Locking mechanism: Rotating the fastening bolt clockwise applies a downward movement to the upper pressure plate. After the upper pressure plate contacts the roller, it forms an inward displacement under the guidance of the first and second wedge plugs, thereby pressing the side pressure plate against the inward baffle and compressing the return spring at the same time. Rotating the fastening bolt counterclockwise applies an upward movement to the upper pressure plate, and the return spring drives the side pressure plate to return to its original position under the guidance of the first and second wedge plugs. Monitoring linkage device: Rotating the fastening bolt clockwise applies a downward movement to the upper pressure plate. The upper pressure plate drives the cam to rotate according to the preset stroke. The cam pushes the control rod, triggering the monitoring indicator light to light up. As the upper pressure plate continues to move downward, the cam protrusion passes over the control rod. The control rod gradually returns to its original position under the action of the thrust spring. Finally, the monitoring indicator light goes out, indicating that the locking mechanism has achieved locking. Attached Figure Description

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", and "around" indicate orientation or positional relationships and are only for the convenience of describing the present utility model and simplifying the description, and should not be construed as limiting the present utility model.

[0024] Example 1: like Figures 1 to 3As shown, this utility model provides a flood control baffle locking mechanism for locking the side of the baffle 22 into the slot 701 of the column 7. A vertical slot 701 is provided on one side of the column 7 for placing the side of the baffle 22; a top cover is fixed to the upper end of the column 7, and a positioning groove is provided on one side of the top cover for placing the base 1.

[0025] Combined Figures 4 to 6 As shown, the locking mechanism includes a base 1 embedded in a positioning groove at the upper end of the column 7, and a vertical fastening bolt 2 threadedly connected to the base 1. The upper end of the fastening bolt 2 has an internal hexagonal head, and the lower end extends out of the base 1; the lower end of the fastening bolt 2 is rotatably connected to an upper pressure plate 3, which can rotate relative to the fastening bolt 2 but cannot move axially relative to it. By rotating the fastening bolt 2, the upper pressure plate 3 can be controlled to move up and down.

[0026] A vertical side pressure plate 4 is provided on one side of the baffle 22, below the upper pressure plate 3. The upper end of the side pressure plate 4 has a T-shaped head 401, and a roller 11 vertically opposite to the upper pressure plate 3 is fixed on the T-shaped head. A plurality of evenly distributed first wedge plugs 5 are fixed on the side pressure plate 4 away from the side. Each first wedge plug 5 is mated with a second wedge plug 6, which is fixed on the inner wall of one side of the slot 701. During operation, the upper pressure plate 3 moves down, pressing down on the side pressure plate 4. At this time, the roller 11 will roll into contact with the lower side of the upper pressure plate 3, allowing the side pressure plate 4 and the upper pressure plate 3 to move relative to each other horizontally upward. At the same time, the inclined surface of the first wedge plug 5 will move relative to the inclined surface of the second wedge plug 6, thereby pushing the side pressure plate 4 inward. Finally, the side pressure plate 4 presses against the side of the baffle 22, locking the baffle 22, while the upper pressure plate 3 restricts the upward movement of the baffle 22.

[0027] Additionally, a positioning block 8 is fixed on the inner wall of the slot 701, located below the T-shaped head 401 of the side pressure plate 4. A vertical slide rod 9 is fixed on the T-shaped head 401, with its lower end slidably connected to the positioning block 8. A reset spring 10, which provides an upward pushing force to the side pressure plate 4, is fitted onto the slide rod 9. When the upper pressure plate 3 moves upward, the reset spring 10 pushes the side pressure plate 4 upward to reset, and the side pressure plate 4 no longer presses against the baffle 22, thus unlocking the baffle 22.

[0028] In another embodiment, a side top plate 12 and a wear-resistant sealing plate 23 are respectively inserted into the inner walls of the slot 701 on both sides of the column 7. The wear-resistant sealing plate 23 is located between the side pressure plate 4 and the baffle 22, and the side top plate 12 is located on the other side of the side pressure plate 4. During operation, the side pressure plate 4 presses the wear-resistant sealing plate 23, and the wear-resistant sealing plate 23 presses the baffle 22; the side top plate 12 presses against the baffle 22 on the other side.

[0029] Example 2: Based on the above embodiment one, combined with Figures 3 to 6As shown, this utility model provides a flood control barrier locking monitoring and linkage device, which is used to indicate the locking process of the locking mechanism.

[0030] The monitoring linkage device includes a monitoring indicator light 13 installed on the base 1. A control rod 14 is slidably connected to the monitoring indicator light 13. The upper end of the control rod 14 has a spring. When the control rod 14 moves upward, the spring presses against the monitoring indicator light 13 and controls the monitoring indicator light 13 to turn on. When the control rod 14 moves away from the monitoring indicator light 13, the monitoring indicator light 13 turns off.

[0031] A cam 15 is located below the control lever 14. The cam 15 is rotatably mounted on a rotating shaft 17, the two ends of which are fixed to ear plates 18, which are fixed to the lower side of the base 1. A connecting plate 19 is rotatably mounted on the rotating shaft 17 on each side of the cam 15. The two connecting plates 19 are fixed to the cam 15 by a connecting bolt 20. A lever bolt 21 connects the two connecting plates 19. A lever 301 is located on the side of the upper pressure plate 3 near the cam 15, and the lever 301 engages with the lever bolt 21.

[0032] A locking block 141 is fixed to the lower end of the control lever 14. The locking block 141 engages with both sides of the cam 15 to prevent the lower end of the control lever 14 from deviating from the cam 15. Simultaneously, a thrust spring 16 is fitted onto the control lever 14. The thrust spring 16 pushes the lower end of the control lever 14 towards the cam 15, maintaining contact between the lower end of the control lever 14 and the cam 15. The cam 15 has protrusions for controlling the lifting and lowering of the control lever 14. During the locking process of the locking mechanism, the locking baffle 22 is engaged. Initially, monitoring indicator 13 is in the off state; After the locking mechanism is started, the upper pressure plate 3 gradually descends, and the paddle 301 on one side of the upper pressure plate 3 pushes the cam 15 to rotate; under the action of the cam 15, the cam 15 first pushes the control lever 14 to move upward, so that the monitoring indicator light 13 lights up, indicating that the locking mechanism is working on the locking baffle 22. Finally, the control lever 14 passes over the protrusion and begins to gradually descend, causing the monitoring indicator light 13 to turn off again, indicating that the locking mechanism has completed the work of locking the baffle 22.
