[0017] The present application is further described in detail below in conjunction with the accompanying drawings.

[0018] The present application embodiment discloses an automatic lifting flood control baffle, referring to Figure 1 , applied to an inlet and outlet channel 1, the inlet and outlet channel 1 includes a carrier 12 and two side walls 11 erected on the carrier 12, and a flood baffle is arranged between the carrier 12 and the two side walls 11 to block the water flow.

[0019] Reference Figure 2 , 3 The flood baffle includes a baffle body 2 and a lifting mechanism. A lifting groove 121 is opened on the carrier 12 of the inlet and outlet channel 1. The baffle body 2 is slidably connected in the lifting groove 121. The lifting mechanism is arranged in the lifting groove 121 for controlling the lifting of the baffle body 2.

[0020] Specifically, the lifting mechanism includes a cylinder 3 installed at the bottom of the lifting groove 121, and the piston rod of the cylinder 3 is fixedly connected to the bottom of the baffle body 2, and the lifting and lowering of the baffle body 2 is controlled by the extension and retraction of the cylinder 3. In this embodiment, two cylinders 3 are symmetrically arranged in the lifting groove 121. Of course, the number of cylinders 3 can be adjusted according to the size of the baffle body 2, and this embodiment does not limit the number of cylinders 3. In addition, in other embodiments, the cylinder 3 can also be replaced by a device with a lifting function such as an oil cylinder.

[0021] The lifting mechanism also includes a liquid level sensor and a control unit. The liquid level sensor is installed at the upper end of the baffle body 2 to monitor the change of the liquid level. The control unit is electrically connected to the liquid level sensor and the cylinder 3 to receive the signal of the liquid level sensor and control the action of the cylinder 3 according to the signal, so that when the liquid level sensor senses the water flow, the cylinder 3 drives the baffle body 2 to rise to block the water flow. In other embodiments, the lifting and lowering of the cylinder 3 can also be manually controlled by setting a control panel.

[0022] Reference Figure 4 , 5 The flood baffle also includes a front baffle 4, a rear support plate 5 and a limit mechanism 6. A guide plate 21 is welded and fixed to the upper end of the baffle body 2. A guide frame 22 is mounted on the guide plate 21 and slides up and down along the guide plate 21. A slide groove 111 connected to the lifting groove 121 is vertically opened on the opposite side of the two side walls 11. The guide frame 22 and the baffle body 2 are slidably connected between the two slide grooves 111.

[0023] The front baffle plate 4 and the rear support plate 5 are respectively located at the front and rear sides of the baffle body 2, and one end of the front baffle plate 4 and the rear support plate 5 is hinged to the guide frame 22, and the other end is in contact with the carrier 12. The carrier 12 is provided with a front groove 122 for the front baffle plate 4 to be laid flat and a rear groove 123 for the rear support plate 5 to be laid flat. When the baffle body 2 is lowered and stored in the lifting groove 121, the front baffle plate 4 and the rear support plate 5 are laid flat in the corresponding front groove 122 and rear groove 123, without occupying the import and export space and without affecting the normal entry and exit of vehicles.

[0024] When the accumulated water acts on the front baffle 4, the direction of the force of the accumulated water on the baffle body 2 can be changed from a lateral force to an oblique downward force, thereby enhancing the supporting strength of the flood control baffle in the raised state.

[0025] The limiting mechanism 6 is used to limit the support of the rear support plate 5 on one end of the carrier 12. That is, when the baffle body 2 rises, the limiting mechanism 6 is moved with the baffle body 2 to the end of the rear support plate 5 supporting the ground, and when the baffle body 2 falls, the limiting mechanism 6 is moved with the baffle body 2 to release the limit support of the end of the rear support plate 5 supporting the ground.

[0026] The rear support plate 5 can provide favorable support behind the baffle body 2 under the action of the limiting mechanism 6, thereby enhancing the safety and reliability of the structure.

[0027] Reference Figure 6 , 7The limiting mechanism 6 includes a limiting rod 61, a linkage rope 62, a rope reel 63, a reset member 64 and a linkage assembly 65. A movable groove 1231 for the limiting rod 61 to move is provided at the bottom of the rear groove 123. The movable groove 1231 extends toward the two side walls 11. The limiting rod 61 is slidably connected in the movable groove 1231 and moves transversely in a direction parallel to the two side walls 11. A slope 1232 connected to one side of the movable groove 1231 is also obliquely provided on the rear groove 123. The limiting rod 61 can move to the rear groove 123 with the help of the slope 1232. A plurality of snap rings 611 are fixed at equal intervals on the outer peripheral side of the limiting rod 61, and an annular snap groove 612 for supporting the rear support plate 5 is formed between adjacent snap rings 611. That is, the rear support plate 5 can be snapped with the annular snap groove 612 to form a limiting support for the ground-supporting end of the rear support plate 5.

[0028] A limiting groove 1233 extending along the movable direction of the limiting rod 61 is also provided on the rear groove 123. The limiting groove 1233 extends to the slope 1232 and the movable groove 1231. The size of the retaining ring 611 is adapted to the limiting groove 1233, so that the limiting rod 61 can fall into the limiting groove 1233, thereby increasing the supporting strength of the limiting rod 61 in the axial direction.

[0029] Reference Figure 6 , 8 A mounting groove 1211 is provided on the groove wall near the notch of the lifting groove 121 and one side of the rear groove 123. The rope reel 63 is rotatably connected between two opposite groove walls of the mounting groove 1211 through a rotating shaft, and the linkage rope 62 is wound on the rope reel 63. A transverse groove 1234 extending along the lateral movement direction of the limiting rod 61 is provided on the rear groove 123. A vertical groove 1235 connecting the transverse groove 1234 and the mounting groove 1211 is also provided on the rear groove 123. The vertical groove 1235 extends along the in-and-out direction of the in-and-out passage 1. One end of the linkage rope 62 passes through the vertical groove 1235 and the transverse groove 1234 in sequence and is fixedly connected to the limiting rod 61. The joint between the vertical groove 1235 and the transverse groove 1234 is set to be rounded to reduce the friction resistance of the linkage rope 62.

[0030] The reset member 64 acts on the limit rod 61, providing the limit rod 61 with elastic force to always move toward the movable groove 1231. The linkage assembly 65 acts between the rope reel 63 and the baffle body 2. During implementation, when the baffle body 2 rises, the rope reel 63 reels the linkage rope 62 through the action of the linkage assembly 65, driving the limit rod 61 to move along the movable groove 1231 to the rear groove 123, and providing limited support for the rear support plate 5. When the baffle body 2 descends, the rope reel 63 releases the linkage rope 62, and under the action of the reset member 64, the limit rod 61 is retracted into the movable groove 1231, releasing the limited support for the rear support plate 5. The entire limiting process is completed automatically without manual operation, thereby improving the practicality and safety of the flood baffle.

[0031] Specifically, refer to Figure 7 , 9 The linkage assembly 65 includes a gear 651 and a rack 652. The gear 651 is coaxially fixedly connected to the rope winding wheel 63. A tooth groove 23 is vertically opened on one side of the baffle body 2 facing the rear groove 123. The rack 652 is fixedly installed in the tooth groove 23 and is located at the lower end of the tooth groove 23.

[0032] When the baffle body 2 moves upward with the rack 652, the gear 651 enters the tooth groove 23. After the baffle body 2 moves up a certain distance, the gear 651 meshes with the rack 652 in the tooth groove 23. Under the action of the gear 651 and the gear 651, the rope reel 63 starts to reel in the linkage rope 62, and pulls the limit rod 61 into the rear groove 123 through the linkage rope 62, so that the supporting end of the rear support plate 5 moving upward with the baffle body 2 can be clamped into the annular clamping groove 612. When the baffle body 2 moves to the guide frame 22 and abuts against the groove wall at the top of the slide groove 111, the baffle body 2 is erected. At the same time, under the action of the annular clamping groove 612, one end of the rear support plate 5 is limited, thereby effectively supporting the baffle body 2.

[0033] When the baffle body 2 is retracted into the lifting slot 121, the baffle body 2 first descends, so that the rack 652 and the gear 651 are separated. When the gear 651 and the rack 652 are separated, the rope reel 63 releases the linkage rope 62, so that the limit rod 61 is retracted into the movable slot 1231 under the action of the reset member 64, and then the rear support plate 5 and the front baffle plate 4 are lowered together with the guide frame 22 and the baffle body 2 under the action of their own weight, until the rear support plate 5 and the front baffle plate 4 are laid flat on the carrier 12.

[0034] In other embodiments, the linkage component 65 can also be replaced by a friction wheel and a friction strip with a rough outer surface. The friction wheel is coaxially fixed on the rope winding wheel, and the friction strip is fixed in the tooth groove. When the baffle body 2 rises, the friction wheel and the friction strip are in contact and form mutual extrusion. The linkage between the baffle body 2 and the rope winding wheel is achieved through the friction force between the friction wheel and the friction strip.

[0035] Reference Figure 6 , 7 The reset member 64 includes an elastic rope, one end of which is fixed to the end of the movable groove 1231 away from the slope 1232, and the other end is fixedly connected to the limit rod 61. In the absence of external force, the elastic rope always generates a pulling force on the limit rod 61, so that the limit rod 61 can be pulled back into the movable groove 1231. The elastic rope can be made of a material with a certain extension capacity, such as rubber. Of course, in other embodiments, the reset member 64 can also be replaced by a tool such as an automatic reel with a reset and rewinding capability, and the present application does not limit the reset member 64.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
