[0027] The present invention is further described below in conjunction with the embodiments. It should be noted that, in this article, words such as "upper", "lower", etc. are only used to facilitate the description of the drawings, and do not limit the direction in actual use, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article, or device.

[0028] like Figure 1-5As shown, an automatic flood defense device includes a water baffle 1 and a main portal structure 8 (a cross-sectional structure is shown in the figure), a sealing strip 3 is provided at the rear end of the main portal structure 8, that is, a circle of sealing strips is installed on the rear side of the main portal structure 8, and the sealing strip can adopt a detachable and replaceable structure so that it can be replaced after a certain period of time; a traction mechanism connected to the water baffle 1 is also provided, and the water baffle 1 is sealed with the sealing strip 3 of the main portal structure 8 at the maximum upward position; the ground behind the water baffle 1 is the indoor ground 11, and the ground in front of the main portal structure 8 is the outdoor ground 19. The water baffle 1 can be used to isolate the indoor ground 11 and the outdoor ground 19 when needed. An automatic locking mechanism 2 is also provided on the main portal structure 8. After the water baffle 1 is squeezed and fitted with the sealing strip 3, the automatic locking mechanism 2 is opened and fixes the water baffle 1 to keep it in a fitted state with the sealing strip 3. It should be noted that the indoor floor 11 described here is only an example. In actual use, even outdoors such as a park gate, a combination of a main door frame structure 8 and a water retaining plate 1 can be used to achieve a flood prevention effect.

[0029] Furthermore, a buoy shell 7 is provided on the front side of the main gantry structure 8, and a buoy 9 whose size is smaller than the internal size of the buoy shell 7 is provided inside the buoy shell 7, the height of the buoy shell 7 is greater than the buoy 9, and an opening connected to the outside is provided on the bottom side of the buoy shell 7, and a position detector 12 is provided inside the buoy shell 7 at a place higher than the top of the initial position of the buoy 9. With such a design, when there is too much water accumulation and the buoy 9 is driven to float up, the buoy 9 can contact the area of ​​the position detector 12, so that the position detector 12 sends a signal to the control system, and drives the traction mechanism to move the water retaining plate 1 upward to achieve the function of blocking the flood. It should be noted that the height of the position detector 12 is only slightly higher than the height of the buoy 9, so that the position detector 12 can be triggered when the buoy 9 is subjected to a slight buoyancy. The control system adopts any computer system or circuit board system that can realize command reception and transmission.

[0030] An automatic sprinkler 15 is provided on the inner side of the top of the buoy shell 7, and the automatic sprinkler 15 is connected to a water pipe and / or a reserve water tank 18, and is equipped with a backup emergency power supply 6. Since floods generally carry a large amount of pollutants such as silt, the automatic sprinkler 15 can be used to clean the inner wall of the buoy 9 and the buoy shell 7, so as to avoid excessive friction between the buoy 9 and the buoy shell 7 due to accumulation of pollutants, resulting in the buoy 9 being unable to move up and down normally, and also avoid other problems such as the position detector 12 being unable to be used normally. The position detector 12 can use an infrared light interrupter, which sends a command when an object blocks the light signal. The model can be ITR20804 Everlight infrared light interrupter.

[0031] A groove is provided on the outdoor ground 19 on the front side of the buoy shell 7 as a flood pre-drainage groove 10. Such a design can drain away the accumulated water caused by the flood as much as possible. When the accumulated water cannot be drained away and a large amount of accumulated water is generated, the position detector 12 will be activated.

[0032] An audible and visual alarm 5 is provided on the main gantry structure 8 or the buoy shell 7. After the position detector 12 is activated, an alarm message is issued to remind relevant personnel to pay attention and take other measures to further improve the flood prevention effect. In order to avoid power outages that may be caused by floods, the audible and visual alarm 5 is connected to the backup emergency power supply 6. Similarly, the control system can also be equipped with a separate backup emergency power supply.

[0033] In one embodiment, the automatic locking mechanism 2 is provided with a plurality of locking heads 22 that can move forward and backward. When the locking head 22 moves to the outside of the automatic locking mechanism 2, the side of the locking head 22 presses against the rear side of the water baffle 1 to fix the water baffle 1. In other embodiments, other forms can be used to fix the water baffle 1 by the automatic locking mechanism 2, such as a spring-type pop-up lock block. A hinge with limited movement is provided at the bottom of the automatic locking mechanism 2, and a block can be set outside the range of movement of the hinge to avoid rotation beyond the range. When the automatic locking mechanism 2 is pulled by an external force, it will rotate to a position where locking can be achieved and remain fixed.

[0034] The locking head 22 is arranged in the moving cavity 21 of the automatic locking mechanism 2, and a limiting threaded ring 23 is provided at the outer end of the moving cavity 21 to limit the outward movement limit position of the locking head 22. A telescopic motor 25 and a telescopic rod 24 are provided on the rear side of the locking head 22, and the position movement is achieved by connecting the telescopic rod 24 with the locking head 22.

[0035] In one embodiment, the traction mechanism includes a hoisting motor 4, a plurality of rope groove pulleys 14, and a traction rope 13. The traction rope 13 is respectively connected to the water retaining plate 1 and the hoisting motor 4 through the rope groove pulley 14. The hoisting motor 4 is fixed to the main gantry structure 8. The hoisting motor 4 can be a model such as JK3t. The traction rope 13 can be a steel cable or the like.

[0036] The rope groove pulley 14 includes pulley one 141, pulley two 142, pulley three 143, pulley four 144, and pulley five 145. The pulley three 143 is arranged on the water retaining plate 1, the pulley one 141 and the pulley two 142 are transversely arranged on the upper side of the main portal structure 8, the pulley four 144 and the pulley five 145 are longitudinally arranged in the middle and lower parts of the main portal structure 8, and the traction rope 13 is sequentially wound around the pulley one 141, the pulley two 142, the pulley three 143, the pulley four 144, and the pulley five 145, and is finally connected to the automatic locking mechanism 2.

[0037] Furthermore, a plate groove 17 for accommodating the water retaining plate 1 is provided on the indoor floor 11, and a travel switch 16 is provided in the plate groove 17. When the water retaining plate 1 moves downward and squeezes, the travel switch 16 sends a command to the control system to open the automatic sprinkler head 15 to wash the inner wall of the buoy shell 7.

[0038] The method of using the utility model is as follows:

[0039] When a flood comes and the water cannot be drained away through the flood pre-drainage groove 10, and the float 9 is driven to move up to the trigger position detector 12, the winch motor 4 is started to drive the traction rope 13 to move the automatic locking mechanism 2, and at the same time drive the water baffle 1 to move up from the plate groove 17 until it is tightly sealed with the sealing strip 3. At this time, the control system allows the automatic locking mechanism 2 to lock the water baffle 1. When the accumulated water is drained away, the water baffle 1 is moved down back into the plate groove 17 through the control system, and the travel switch 16 is triggered. At this time, the automatic sprinkler head 15 is driven to flush the inner wall of the float shell 7 to ensure that the float 9 can move freely up and down inside the float shell 7. At the same time, the automatic locking mechanism 2 is also returned to its position.
