Description
Technical Field
[0001] The utility model belongs to the technical field of auxiliary devices for culverts of salt field production hydraulic structures, and in particular relates to a device for automatically opening a drainage function of a salt field culvert. Background Art
[0002] According to the requirements of the salt production process, the water route and flow of the entire beach field need to be planned and graded, and some evaporation ponds and ditches need to be frequently unidirectional. For example, all the fresh water (rainwater) in the entire beach field needs to be discharged into the sea. In order to prevent seawater from backflowing, gates need to be set up in the drainage channel for control. However, due to the influence of seawater tides, the gates need to be operated frequently. Each time the gates are opened and closed, electricity or special operators are required to operate. At the same time, due to frequent opening and closing, wooden gates are easily worn, difficult to repair, and have a shortened service life, which increases production and operation costs.
[0003] Therefore, based on the above problems, it is an urgent problem to design a device that can overcome the problem that frequent water level changes in the existing production process require frequent manpower or electricity to start water control. Utility Model Content

[0017] In the above technical solution, the diameter of the bolt connector is 25 mm, and the connection is completed by passing through the hole in the angle iron and the inverted U-shaped iron.

Each two are welded to the outside of the embedded iron part in parallel as a group. The inner side spacing of each group of angle irons is 180 mm, and the spacing between each group of angle irons is 300 mm.
[0038] Furthermore, in the present embodiment, it can also be considered that the inverted U-shaped connecting member is an inverted U-shaped iron 6, and the inverted U-shaped iron 6 is vertically fixed to the upper side of the wooden flap door 2 by bolts 7.

[0044] Working principle of the utility model: The utility model controls the automatic opening and closing of the gate by utilizing the deadweight of the wooden flap gate and the water level difference on both sides. The opening and closing process of the wooden flap gate does not require manual or electric control. It can replace traditional culverts in some drainage areas, thereby saving operating costs. At the same time, the device is simple and convenient to install and maintain, and the cost is lower.
[0045] Working process of the utility model: When the utility model is in the process of opening and closing the device, the traditional wooden gate needs to be controlled by manual or electric operation of the gate opening and closing machine. After the use of this device, the wooden flap gate uses its own weight and the water level difference on both sides to form a one-way check valve that automatically opens and closes. When the water level on the inlet side is higher than the water level on the outlet side, the water pressure on the inlet side pushes the gate to open, and the brine is discharged downstream; when the water level on the inlet side is lower than the outlet side, the water pressure on the outlet side and the deadweight of the wooden gate push the wooden flap gate to close, blocking the downstream brine from flowing back upstream. The device is used in the operations of retaining bottom water in one step and one card and tidal intake in the salt field brine making process, which can effectively prevent high-concentration brine from flowing back to the upper evaporation pool. It can be used in the salt field desalination operation to effectively prevent seawater from flowing back into the salt field and improve the brine making effect.
[0046] The utility model provides a device for automatically opening the drainage function of the salt pan culvert, which can effectively prevent brine backflow, and does not require manual or electric control during production and use, which alleviates the current problem of shortage of personnel in domestic salt fields and reduces production costs. The device is simple and practical, low in cost, simple to install, easy to maintain, and has good use effect.
