Description

Technical Field

[0001] This utility model relates to the field of hinge dam technology, and in particular to an automatic leveling device for hinge dams. Background Technology

[0002] The hinged dam utilizes the hydraulic "three-hinged variable amplitude motion mechanism principle," an optimized combination with traditional sluice gates. It is suitable for various hydraulic engineering conditions and geological conditions, and is widely used in water conservancy and hydropower projects, water ecological civilization projects, and urbanization projects, including river landscaping, irrigation and water storage, and reservoir expansion. This technology has obtained a utility model patent issued by the State Intellectual Property Office and has been included in the Ministry of Water Resources' 2014 Key Promotion and Guidance Catalogue of Advanced and Practical Water Conservancy Technologies.

[0003] The existing hinge dams are not equipped with automatic leveling devices, so the impact of water during use will affect their stability and cause them to tilt. If they cannot be restored to their original state in time after tilting, major dangerous accidents such as dam breaches may occur.

[0004] Therefore, it is necessary to design an automatic leveling device for hinge dams to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic leveling device for hinge dams to solve the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model discloses an automatic leveling device for a hinge dam, comprising a base and uprights mounted on both ends of the top of the base. A hinge dam is provided between the two uprights, and the bottom of the hinge dam is rotatably connected to the bottom of the uprights. The device is characterized in that: a baffle is provided on the inner side of each upright, the top of the hinge dam is on the baffle, and the hinge dam is connected to the base via hydraulic cylinder one and hydraulic cylinder two. A groove one is provided on the top of each of the two uprights near the hinge dam, and an infrared sensor one is installed in the groove one, pointing towards the side wall of the hinge dam. The two infrared sensors one are electrically connected to hydraulic cylinder one and hydraulic cylinder two, respectively. A groove three is provided on the side of the hinge dam facing away from the water, and an electronic level is installed in the groove three, which is connected to an alarm mechanism.

[0008] Furthermore, the bottom of the hinge dam is rotatably connected to the bottom of the upright frame via a pivot.

[0009] Furthermore, the bottoms of hydraulic cylinder one and hydraulic cylinder two are hinged to the base, and the piston ends of hydraulic cylinder one and hydraulic cylinder two are hinged to the hinge dam.

[0010] Furthermore, sealing strips are provided at the positions where the baffle and the hinge dam are in contact.

[0011] Furthermore, the top of the hinge dam has a strip groove at the position of the baffle, and the baffle has an insert plate at the position corresponding to the strip groove. The insert plate is inserted into the strip groove, and the end of the insert plate abuts against the bottom of the strip groove. A second groove is formed on the side wall of the strip groove, and an infrared sensor is provided in the second groove. The second infrared sensor points to the insert plate, and the two second infrared sensors are electrically connected to the first hydraulic cylinder and the second hydraulic cylinder, respectively.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This invention uses two different sets of infrared sensors to detect changes in the distance between the hinge dam and the insert plate, thereby controlling the fine adjustment of the two hydraulic cylinders to ensure the hinge dam resets as quickly as possible and guarantee its safety. An electronic level also senses whether the hinge dam has not been reset for an extended period of time, and if not, it quickly alarms to remind the staff. Attached Figure Description

[0019] like Figure 1-3 As shown, an automatic leveling device for hinge dams includes a base 1 and uprights 2 installed on both ends of the top of the base 1. A hinge dam 3 is provided between the two uprights 2, and the bottom of the hinge dam 3 is rotatably connected to the bottom of the uprights 2 via a pivot 9.

[0020] The inner side of the upright frame 2 is provided with a baffle 4, and the hinge dam 3 is abutted on the baffle 4. Sealing strips are provided at the positions where the baffle 4 and the hinge dam 3 are in contact.

[0021] The hinge dam 3 is connected to the base 1 by hydraulic cylinder 5 and hydraulic cylinder 6. The bottom of hydraulic cylinder 5 and hydraulic cylinder 6 are hinged to the base 1, and the piston end of hydraulic cylinder 5 and hydraulic cylinder 6 is hinged to the hinge dam 3.

[0022] The top of each of the two uprights 2 is provided with a groove 7 on the side near the hinge dam 3. An infrared sensor 8 is installed in the groove 7. The infrared sensor 8 points to the side wall of the hinge dam 3. The two infrared sensors 8 are electrically connected to the hydraulic cylinder 5 and the hydraulic cylinder 6, respectively.

[0023] A groove 3 14 is provided on the side of the hinge dam 3 facing away from the water. An electronic level 15 is installed in the groove 3 14 and is connected to the alarm mechanism.

[0024] The hinge dam 3 has a strip groove 10 at the position of the baffle 4. The baffle 4 has an insert plate 11 at the position of the strip groove 10. The insert plate 11 is inserted into the strip groove 10, and the end of the insert plate 11 rests on the bottom of the strip groove 10. The side wall of the strip groove 10 has a second groove 12. The second groove 12 has an infrared sensor 13. The second infrared sensor 13 points to the insert plate 11.

When a change is detected, hydraulic cylinders 5 and 6 adjust the hinge dam 3 until the electronic level 15 remains level. If the electronic level 15 is not level for an extended period, the alarm mechanism will sound to alert staff that there may be a problem with the system and it needs to be resolved promptly.
