Description

Technical Field

[0001] This utility model belongs to the field of gate technology, specifically relating to a high-head emergency gate suitable for venting and sand-discharging bottom hole. Background Technology

[0002] Emergency gates play a crucial role in water conservancy projects. They can cut off water flow in flowing water to handle or contain accidents occurring downstream. They can also be quickly closed in emergencies to stop the flow of water, prevent the accident from escalating, and protect downstream safety. At the same time, the installation of emergency gates can improve the operational efficiency and safety of water conservancy projects. Therefore, the hydraulic performance and dynamic performance of the gate structure of emergency gates are directly related to the operational reliability, economic rationality, and safety of the entire water conservancy project. In actual use, existing emergency gates are easily blocked by silt accumulated on the upstream side, resulting in the need for large opening and closing forces. Therefore, large-capacity opening and closing equipment is required, which brings many inconveniences in dealing with emergencies. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-head emergency gate suitable for venting and sand-discharging bottom holes.

[0004] To achieve the above objectives, this utility model provides a high-head emergency gate suitable for venting and sand-discharging bottom holes, comprising a gate body, four main wheel holes on the outer wall of the gate body, main wheels fixedly installed inside the main wheel holes, a pair of first lifting lugs fixedly connected to the top of the gate body, a door leaf structure provided on one side of the outer wall of the gate body, the door leaf structure including a baffle plate, a plurality of first reinforcing ribs fixedly connected to one side of the outer wall of the baffle plate, and evenly distributed second reinforcing ribs fixedly connected between the first reinforcing ribs, and a movable cavity provided inside the gate body, with slide rails fixedly connected to both sides of the inner wall of the movable cavity, and a separation component extending out of the movable cavity housed inside the movable cavity via the slide rails.

[0005] In the above technical solution, the second reinforcing rib further includes a cutting portion, the bottom of which is fixedly connected to a reinforcing portion, and the cutting portion is configured as an arched structure.

[0006] In the above technical solution, the reinforcing part is further configured as an inverted arch shape, and a flow hole is also provided on the top of the outer wall of the reinforcing part.

[0007] In the above technical solution, the separation component further includes a movable door slidably connected inside the movable cavity. A pair of second lifting lugs are fixedly connected to the top of the movable door. A connecting door is provided above the second lifting lugs. A first pull rope is fixedly connected to the top of the connecting door. The first pull rope is pulled up and down by an external suspension device. The connecting door and the second lifting lugs are connected by a steel wire pull rope.

[0008] In the above technical solution, a sloping door is further provided on one side of the outer wall of the movable door.

[0009] In the above technical solution, the main shaft of the main wheel hole is a tapered bearing.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] By incorporating structures such as cutting sections and flow holes, the sharp arched structure can effectively cut the silt attached to the gate as it moves upward, thereby breaking up the dense accumulation of mud and sand, reducing the pressure on the gate body, and thus reducing the frictional resistance required to open the gate, making it easier to open.

[0012] By incorporating structures such as a movable gate and a movable cavity, the movable gate and the gate body together form a barrier, allowing the gate to move upwards without requiring the movable gate to move as well. Therefore, it is only blocked by the mud and sand adhering to the gate body. At the same time, pulling the movable gate does not require moving the mud and sand on the gate body, further reducing the frictional resistance required to open the gate, making it easier to open. A slight increase in the capacity of the opening and closing equipment can meet the opening requirements. This structure is easier to process and manufacture, saves on production and manufacturing costs, and is more conducive to operation. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-4 The diagram shows a high-head emergency gate for venting sand and wastewater discharge at the bottom orifice, comprising a gate body 1. Four main wheel holes 4 are formed on the outer wall of the gate body 1, and main wheels 2 are fixedly installed inside the main wheel holes 4. A pair of first lifting lugs 6 are fixedly connected to the top of the gate body 1. A gate leaf structure 5 is provided on one side of the outer wall of the gate body 1. The gate leaf structure 5 includes a baffle plate 8. Several first reinforcing ribs 9 are fixedly connected to one side of the outer wall of the baffle plate 8. Evenly distributed second reinforcing ribs 10 are fixedly connected between the first reinforcing ribs 9. The second reinforcing ribs 10 include a cutting portion 11, the bottom of which... The fixed connection has a reinforcing part 12, and the cutting part 11 is set with an arched structure. When the gate is lifted upward, the arched structure 11 can cut the silt, allowing it to pass through the silt more smoothly, thereby reducing the adhesion of the silt and thus reducing the opening and closing force. The reinforcing part 12 is set with an inverted arched structure, and the top of the outer wall of the reinforcing part 12 is also provided with a flow hole 13. When the gate is lifted, the silt accumulated on 12 will flow downward from 13, thereby further reducing the adhesion of the silt and further reducing the force required for opening and closing.

[0020] The gate body 1 also has an internal movable cavity 14. The inner walls of the movable cavity 14 are fixedly connected to slide rails 19 on both sides. The movable cavity 14 is equipped with a separation component 3 that extends out of the movable cavity 14 through the slide rails 19. The separation component 3 includes a movable door 15 that is slidably connected inside the movable cavity 14. A pair of second lifting lugs 17 are fixedly connected to the top of the movable door 15. A connecting door 18 is provided above the second lifting lugs 17. A first pull rope 7 is fixedly connected to the top of the connecting door 18. The first pull rope 7 is pulled up and down by an external suspension device. The connecting door 18 and the second lifting lugs 17 are connected by a steel wire pull rope. The movable door is driven by a separate suspension device and thus moves independently of 1. Therefore, when the gate moves upward, it is only blocked by the mud and sand attached to 1, thereby further reducing the force required for opening and closing.

[0021] An inclined door 16 is provided on one side of the outer wall of the movable door 15. This arrangement makes it easier to access the interior of the silt when the gate is closed.

[0022] The main shaft of the main wheel hole 4 is a tapered bearing. This design effectively reduces the frictional resistance during the opening and closing of the gate.

[0023] Working principle:

[0024] By setting up structures such as the cutting section 11 and the flow hole 13, the sharp arched structure can effectively cut the silt attached to it during the upward movement of the gate, thereby breaking the dense accumulation of mud and sand, reducing the pressure on the gate body 1, and thus reducing the frictional resistance required to open the gate, making it easier to open the gate.

[0025] By setting up structures such as the movable gate 15 and the movable cavity 14, the movable gate 15 and the gate body 1 together form a barrier, so that when the gate moves upward, it does not need to move the movable gate 15. Therefore, it only needs to be blocked by the mud and sand attached to the gate body 1. At the same time, pulling the movable gate 15 does not need to move the mud and sand on the gate body 1, thereby further reducing the frictional resistance required to open the gate, making the gate opening easier. Slightly increasing the capacity of the opening and closing equipment can meet the gate opening requirements. This structure is easier to process and manufacture, saves production and manufacturing costs, and is more conducive to operation.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
