Description

Technical Field

[0001] The utility model relates to the technical field of water gates, in particular to a gate with a crushing function. Background Art

[0002] The main function of the gate is to regulate the water flow. By controlling the degree of opening of the gate, the flow rate and flow rate of the water can be controlled. This helps to maintain the stability of water supply and the ecological balance of the basin.

[0003] However, the opening of the gate can easily cause some solid waste such as tree branches or plastic boards from upstream to enter the gate along with the water flow. On the one hand, this may block the gate. On the other hand, these solid wastes will flow downstream and have an adverse effect on the power generation equipment. Utility Model Content

[0004] The utility model aims to provide a gate with a crushing function, by arranging a crushing device upstream of the gate, so as to crush the solid waste upstream, thereby avoiding the blockage of the gate by the solid waste or the adverse effect on the power generation equipment.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a gate with a crushing function, including a gate frame and a gate body slidably installed on the gate frame, a crushing device is fixedly installed on the gate frame on the upstream side of the gate body, the crushing device includes a crushing frame installed on the gate frame and two crushing rollers rotatably installed on the crushing frame side by side, the two crushing rollers rotate in opposite directions and rotate relative to each other, and a rotating drive device for driving the two crushing rollers to rotate is fixed on the top of the crushing frame; a filter screen is fixedly installed in the area between the crushing roller and the crushing frame, and the filter screen prevents solid waste from entering between the crushing roller and the crushing frame.

[0006] After adopting the above structure, when it is necessary to open the gate, the gate driving device drives the gate body to slide upward on the gate frame, thereby opening the gate; water flows from the gate to the downstream through the filter, while solid waste cannot pass through due to the obstruction of the filter. When the water flow impacts the solid waste and enters the crushing roller area, the rotating driving device drives the crushing roller to rotate, thereby crushing the solid waste. The crushed solid waste enters the downstream with the water flow, thereby avoiding large pieces of solid waste from clogging the gate or causing adverse effects on the power generation equipment.

[0007] In order to improve the guiding function of the filter screen for solid waste, the filter screens on both sides of the crushing roller are in a trumpet shape.

[0008] In order to improve the strength of the filter, the filter has an arc-shaped structure.

[0009] In order to prevent the filter from being deformed by the impact of water flow, a reinforcing rod is fixed on the inner arc surface of the filter, and the reinforcing rod is fixed on the crushing frame.

[0010] In order to realize the position adjustability of the crushing device, the crushing device is installed on the gate frame in an up-and-down sliding manner, and a sliding driving device for driving the crushing device to slide up and down is arranged on the gate frame.

[0011] In order to ensure that the crushing device slides more smoothly, guide wheels are arranged on both sides of the crushing frame, and slide rails cooperating with the guide wheels are arranged on the gate frame.

[0012] In order to ensure that the crushing device has stronger sliding stability, the guide wheel is a U-shaped wheel or a V-shaped wheel, and a limiting strip matching with the guide wheel is arranged on the slide rail, and the guide wheel slides along the limiting strip.

[0013] After adopting the above technical solution, the beneficial effects of the utility model are:

[0014] The utility model discloses a gate with a crushing function, which solves the technical problem in the prior art that the existing gates are easily blocked by solid waste or large particles of solid waste flow to the downstream, causing adverse effects on power generation equipment. The utility model provides a crushing device upstream of the gate to crush the upstream solid waste, thereby avoiding blockage of the gate by the solid waste or adverse effects on the power generation equipment.

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] The positions mentioned in this specification are based on the positions of the gate with crushing function of the utility model when it is working normally, and do not limit its positions during storage and transportation. They only represent relative position relationships, not absolute position relationships.

[0020] like Figure 1As shown, a gate with a crushing function includes a gate frame 1, which is fixedly mounted on gate piers on both sides. A gate body 2 is slidably mounted on the gate frame 1, and a gate driving device 21 is arranged above the gate body 2. The gate driving device 21 drives the gate body 2 to slide up and down on the gate frame 1, thereby opening or closing the gate, thereby controlling the flow of water. The gate driving device 21 can be a cylinder, an electric cylinder, or a hoist, as long as it can pull the gate body 2 upward to open the gate, and this embodiment does not limit this.

[0021] like Figure 1 and Figure 2 As shown in common, a crushing device 3 is installed on the gate frame 1 at the upstream side of the gate body 2. The crushing device 3 includes a crushing frame 31 fixed on the gate frame 1 and two crushing rollers 32 installed on the crushing frame 31 in parallel. The two crushing rollers 32 rotate in opposite directions and rotate relative to each other. A rotation driving device 321 is fixed on the top of the crushing frame 31 to drive the two crushing rollers 32 to rotate; the rotation driving device 321 can be set as one, and the rotation direction of the two crushing rollers 32 can be controlled by a transmission element such as a gear transmission, or two can be set, one on each crushing roller 32, so as to realize the separate control of the two crushing rollers 32. In order to simplify the transmission element, the present embodiment has two rotation driving devices 321 to realize the separate drive of the two crushing rollers 32. The crushing rollers 32 are provided with crushing impellers, and the crushing impellers on the two crushing rollers 32 cross each other to realize extrusion crushing. This structure can refer to the structure of the crusher. In this embodiment, the rotating drive device 321 is a motor, and the motor is located above the crushing frame 31. In order to prevent water from entering the motor, the water level height of the water flow must be reasonably controlled, and a waterproof cover or other motor waterproof measures can be provided on the outside of the motor to prevent water from entering the motor.

[0022] A filter screen 33 is fixedly installed in the area between the pulverizing roller 32 and the pulverizing frame 31. One side of the filter screen 33 is fixed to the side of the pulverizing roller 32, and the other side is fixed to the pulverizing frame 31. The filter screen 33 covers the area between the pulverizing roller 32 and the pulverizing frame 31, thereby preventing solid waste from entering between the pulverizing roller 32 and the pulverizing frame 31.

[0023] When the gate needs to be opened, the gate driving device 21 drives the gate body 2 to slide upward on the gate frame 1, thereby opening the gate; water flows from the gate to the downstream through the filter screen 33, while solid waste cannot pass through due to the obstruction of the filter screen 33. When the water flow impacts the solid waste and enters the crushing roller 32 area, the rotating driving device 321 drives the crushing roller 32 to rotate, thereby crushing the solid waste. The crushed solid waste enters the downstream with the water flow, thereby avoiding large pieces of solid waste from clogging the gate or causing adverse effects on the power generation equipment.

[0024] In order to improve the guiding function of the filter screen 33 for the solid waste, the filter screens 33 on both sides of the crushing rollers 32 are in a trumpet shape, so that the solid waste can be guided into between the crushing rollers 32 .

[0025] In order to improve the strength of the filter 33, the filter 33 is in an arc structure. Further, in order to prevent the filter 33 from being deformed by the impact of the water flow, a reinforcing rod 331 is fixed on the inner arc surface of the filter 33, the reinforcing rod 331 abuts against the inner arc surface of the filter 33, and the reinforcing rod 331 is fixed on the crushing frame 31.

[0026] Embodiment 2:

[0027] In order to achieve the position adjustability of the crushing device 3 in this embodiment, the crushing device 3 is installed on the gate frame 1 in a sliding manner, and a sliding drive device 34 is provided on the gate frame 1 to drive the crushing device 3 to slide up and down. The sliding drive device 34 drives the crushing device 3 to slide up and down. When the water quality is good and the crushing device 3 is not needed, the crushing device 3 can be raised by the sliding drive device 34 to avoid blocking the water outlet and ensure smoother water discharge. When the water quality is poor and the crushing device 3 is needed, the crushing device 3 can be dropped by the sliding drive device 34 to cover the water outlet and prevent solid waste from flowing down.

[0028] In this embodiment, the sliding drive device 34 is a traction rope elevator, which controls the rise of the crushing frame 31, and the falling process adopts gravity. In actual application, the sliding drive device 34 can also be changed to an electric cylinder or a pneumatic cylinder to control the lifting and lowering. This embodiment does not limit this, and its specific structure can also be deformed and combined according to the existing structure.

[0029] In order to guide the lifting of the crushing device 3, a slide rail 11 is provided on the gate frame 1. The slide rail 11 is a groove-shaped structure. Guide wheels 311 are provided on both sides of the crushing frame 31, and the guide wheels 311 slide up and down in the slide rail 11.

[0030] In order to achieve the limiting effect and prevent the crushing device 3 from shaking, the guide wheel 311 is a U-shaped wheel or a V-shaped wheel, and a limiting strip matching with it is provided on the slide rail 11. The U-shaped groove or V-shaped groove of the guide wheel 311 is stuck on the limiting strip, so that it slides along the limiting strip.

[0031] The utility model discloses a gate with a crushing function, which solves the technical problem in the prior art that the existing gates are easily blocked by solid waste or large particles of solid waste flow to the downstream, causing adverse effects on power generation equipment. The utility model provides a crushing device upstream of the gate to crush the upstream solid waste, thereby avoiding blockage of the gate by the solid waste or adverse effects on the power generation equipment.
