Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy gates, and more specifically to a water conservancy gate. Background Art

[0002] Gates are control facilities used to close and open water discharge channels. They can be used to intercept water flow, control water level, regulate flow, discharge silt and floating objects, etc. The huge water pressure will cause a great impact on the gates, which will have an adverse effect on the sealing of the gates.

[0003] China Patent Authorization Announcement No.: CN214656834U provides a hydraulic gate. This scheme provides a buffer mechanism. When discharging flood water, the water flows from the groove and the wedge-shaped protrusion to the turntable and impacts the blades, so that the kinetic energy of the water flow drives the turntable to rotate around the shaft, which can consume part of the impact force of the water flow. At the same time, the water flow impacts the movable plate and compresses the spring, so that the energy of the water flow impact is converted into the elastic potential energy of the spring, which can also play a buffering role.

[0004] However, there are many floating objects in the water flow of the waterproof channel, which are easy to entangle on the blades in this scheme. Long-term accumulation can easily cause the shaft to get stuck, thus affecting the buffering effect of this scheme. The shaft and blades of this scheme are both set underwater, which causes inconvenience to the cleaning of the blades. Therefore, a water conservancy gate is proposed to address the above problems. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a hydraulic gate, which is provided with a plurality of rotating rollers and blades to consume the impact force of part of the water flow in the flow channel body, slow down the flow rate of the water flow, and buffer the water flow, thereby protecting the gate. Taking into account that a large amount of floating objects will be retained on the blades during long-term use, affecting the normal use of the rotating rollers and blades, the entire buffer assembly can be raised to the upper side of the flow channel body and away from the water area by starting the servo motor, so that the user can easily clean the rotating rollers and blades on the buffer assembly, thereby improving the service life of the device and facilitating the maintenance personnel to clean the device.

[0007] 2. Technical solution

[0010] Furthermore, the buffer assembly includes a pair of lifting blocks, the pair of lifting blocks are slidably connected to the inner walls of a pair of lifting grooves respectively, and the pair of lifting blocks are fixedly connected to a pair of support rods at one end close to each other.

[0011] Furthermore, a pair of lifting blocks are each provided with a set of sliding grooves at one end close to each other, and the two sets of sliding grooves are symmetrical to each other.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) The present solution is provided with a plurality of rotating rollers and blades, which are used to consume the impact force of part of the water flow in the flow channel body, slow down the flow velocity of the water flow, and play a buffering role on the water flow, thereby protecting the gate. Considering that a large amount of floating objects will be trapped on the blades during long-term use, affecting the normal use of the rotating rollers and blades, the entire buffer assembly can be raised to the upper side of the flow channel body and away from the water area by starting the servo motor, so that the user can easily clean the rotating rollers and blades on the buffer assembly, thereby increasing the service life of the device and facilitating the maintenance personnel to clean the device.

Therefore, a telescopic rod and a spring are set between the slider and the slide groove. When the water flow impacts the blade, it will push the slider to move toward the gate, and then the slider will slide in the slide groove, causing the telescopic rod to contract and squeeze the spring at the same time, thereby converting the energy of the water flow impact into the elastic potential energy of the spring, reducing the impact of the water flow, protecting the rotating roller and the blades, and improving the practicality of the device.

[0033] Example:

[0034] See also Figure 1 The hydraulic gate comprises a bracket 1, a hydraulic rod 2 and a flow channel body 4. A pair of hydraulic rods 2 are fixedly connected to the inner end of the bracket 1. The output ends of the pair of hydraulic rods 2 are fixedly connected to the gate 3. The outer end of the gate 3 is tightly abutted against the inner wall of the flow channel body 4. When it is necessary to control the water flow, the hydraulic rod 2 is opened and closed to open or close the gate 3. When the gate 3 is opened, the water flow can freely pass through the opening of the gate 3, and when the gate 3 is closed, the water flow is blocked in front of the gate 3, thereby realizing the control of the water flow. The inner wall of the flow channel body 4 is fixed. A pair of symmetrical mounting blocks 5 are connected, and a lifting groove 6 is provided at one end of the pair of mounting blocks 5 close to each other. A buffer component 7 is arranged between the pair of mounting blocks 5. Since the water pressure of the water flow in the flow channel body 4 is relatively large and will cause a greater impact on the gate 3, the present solution is provided with a buffer component 7 to buffer the water flow. At the same time, the buffer component 7 has a lifting function. During long-term use, a large amount of floating objects will be trapped on the blade 705. The user can clean the blade 705 by lifting the buffer component 7 above the flow channel body 4.

[0035] See also Figure 2-3The buffer assembly 7 includes a pair of lifting blocks 701, which are respectively slidably connected to the inner walls of a pair of lifting grooves 6. A pair of supporting rods 711 are fixedly connected to one end of the pair of lifting blocks 701 close to each other. The entire buffer assembly 7 can be raised and lowered through the sliding connection between the pair of lifting blocks 701 and the pair of lifting grooves 6. The setting of the pair of supporting rods 711 connects the pair of lifting blocks 701 together, so that the pair of lifting blocks 701 can be lifted and lowered synchronously.

[0036] A pair of lifting blocks 701 are each provided with a set of sliding grooves 702 at one end close to each other, and the two sets of sliding grooves 702 are symmetrical to each other.

[0037] Slide blocks 703 are slidably connected in the plurality of slide grooves 702 , a rotating roller 704 is rotatably connected between a pair of the slide blocks 703 , and a plurality of evenly distributed blades 705 are fixedly connected to the outer ends of the plurality of rotating rollers 704 .

[0038] In this solution, a plurality of rotating rollers 704 are provided to buffer the water flow. When the water flow in the flow channel body 4 impacts the gate 3, it will first pass through the plurality of rotating rollers 704, and the water flow impacts the blades 705. The blades 705 drive the rotating rollers 704 to rotate, thereby consuming part of the impact force of the water flow, slowing down the water flow velocity, and buffering the water flow.

[0039] A rack 710 is fixedly connected to one end of the right lifting block 701 near the lifting groove 6, and a servo motor 708 is fixedly connected to the inner wall of the right lifting groove 6. A gear 709 is fixedly connected to the output end of the servo motor 708. The gear 709 is meshingly connected with the rack 710. By starting the servo motor 708, the gear 709 can be driven to rotate. Since the gear 709 is meshingly connected with the rack 710, the gear 709 drives the right lifting block 701 to climb upward, and then drives the left lifting block 701 to rise synchronously, so that the entire buffer assembly 7 rises to the upper side of the flow channel body 4 and leaves the water area, so that the user can easily clean the rotating roller 704 and the blade 705 on the buffer assembly 7.

[0040] One end of each of the multiple sliders 703 is fixedly connected to a telescopic rod 706, and the end of the telescopic rod 706 away from the slider 703 is fixedly connected to the inner wall of the slide groove 702, and a spring 707 is provided in the outer sleeve of the telescopic rod 706. The water flow will not only impact the gate 3, but also impact the rotating roller 704 and the blade 705, which may easily cause damage to them. In this solution, a telescopic rod 706 and a spring 707 are provided between the slider 703 and the slide groove 702. When the water flow impacts the blade 705, the slider 703 will be pushed to move in the direction of the gate 3, thereby causing the slider 703 to slide in the slide groove 702, causing the telescopic rod 706 to contract and squeezing the spring 707 at the same time, thereby converting the energy of the water flow impact into the elastic potential energy of the spring.

[0041] Working principle:

[0042] When in use, the hydraulic rod 2 is operated to open and close to open or close the gate 3. When the gate 3 is open, the water flow can freely pass through the opening of the gate 3, and when the gate 3 is closed, the water flow is blocked in front of the gate 3, thereby realizing the control of the water flow. When the water flow in the flow channel body 4 hits the gate 3, it will first pass through a plurality of rotating rollers 704, and the water flow hits the blades 705. The blades 705 drive the rotating rollers 704 to rotate, consuming part of the impact force of the water flow, slowing down the flow rate of the water flow, and playing a buffering role on the water flow. When the water flow hits the blades 705, it will push the slider 703 to move in the direction of the gate 3, and then The slider 703 slides in the slide groove 702, the telescopic rod 706 contracts, and the spring 707 is squeezed at the same time, so that the energy of the water flow impact is converted into the elastic potential energy of the spring. During long-term use, a large amount of floating objects will be trapped on the blade 705. By starting the servo motor 708, the gear 709 can be driven to rotate. The gear 709 drives the right lifting block 701 to climb upward, and then drives the left lifting block 701 to rise synchronously, so that the entire buffer assembly 7 rises to the upper side of the flow channel body 4 and leaves the water area, so that the user can easily clean the rotating roller 704 and the blade 705 on the buffer assembly 7.

[0043] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
