Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy project flow-blocking devices, and specifically relates to a water conservancy project flow-blocking device. Background Technique

[0002] The flow-blocking devices in water conservancy projects are mainly used to control water flow, regulate water levels, prevent floods from overflowing, and achieve specific water conservancy functions. The sluice mechanism is a common flow-blocking device. The sluice mechanism can adjust the flow rate and water level of the water flow in the river or channel by opening or closing the gate, meeting different needs such as irrigation, shipping, and power generation. During floods, closing the sluice mechanism can block the flood and prevent the flood from flowing back; when drainage is needed, opening the sluice mechanism can drain the waterlogging.

[0003] During the long-term erosion of the atmospheric environment and chemical substances in the water flow, the gate plate of the sluice is often damaged. The gate plate of the sluice is usually submerged underwater or suspended in the air, making it very inconvenient for inspection and maintenance. For this reason, we propose a water conservancy project flow-blocking device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water conservancy project flow-blocking device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A water conservancy project flow-blocking device, including a gate body, and further including a scraping plate installed on the gate body. The scraping plate is used to clean the attachments on the gate plate. A lifting frame is fixedly installed on the scraping plate. A ball box is rollingly connected to the lifting frame. The ball box is fixedly connected to a slide rail groove. The ball box can drive the slide rail groove to move up and down on the lifting frame. One side of the slide rail groove is provided with a detector. The detector is rotatably connected to a pulley group. The pulley group is in rolling contact with the inner wall of the slide rail groove. The detector is fixedly connected to a side empty cylinder. An impact hammer is in sliding contact with the side empty cylinder. The impact hammer is fixedly connected to a spring group. The spring group is fixedly connected to a spring bracket. The spring bracket is fixedly installed on the side empty cylinder. The side empty cylinder is also rotatably connected to a gear rod. A cam is fixedly installed on the gear rod. The detector is also fixedly connected to a receiving rod. The receiving rod is in sliding contact with a receiving cylinder. The receiving cylinder is fixedly connected to a receiving port. The receiving cylinder is in rolling contact with the gear rod.

[0006] Preferably, the pulley group includes two pairs of pulleys, and the slide rail group includes two slide rails.

[0007] Preferably, a pair of pulleys away from the detector are in rolling contact with the upper wall slide rail in the slide rail groove, and a pair of pulleys close to the detector are in rolling contact with the lower wall slide rail in the slide rail groove.

[0008] Preferably, a slide rail group is fixedly arranged in the slide rail groove, and the slide rail group is used for the pulley group to roll thereon.

[0009] Preferably, a channel support is fixedly installed on the gate body, a channel plate is fixedly installed on the channel support, and a guardrail is fixedly installed on the channel plate.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] By providing a detector and an impact hammer, a receiving rod and a receiving port connected thereto, the present utility model can automatically detect the internal structure of the gate plate, check the damage of the gate plate caused by natural environment erosion, and eliminate risks.

[0012] By providing a cam, a gear rod, a spring group and a receiving cylinder with a gear groove, during the process that the cam pushes the impact hammer and stretches the spring group to store energy, the receiving port can be driven to approach the gate plate by the linkage rotation of the gear rod at the same time. When the receiving port is closely attached to the surface of the gate plate, the spring stores energy to the longest position and is released, so that the impact hammer strikes the gate plate to generate an impact elastic wave.

[0013] By providing a lifting frame, a ball box and a slide rail groove, the present utility model can automatically control the up and down lifting and horizontal movement of the detector, so that the detector covers all areas of the gate plate for detection.

[0014] By providing a misaligned pulley group and a slide rail group, the present utility model can ensure the stability of the detector, and the direction of the supporting force of the pulley group is perpendicular to the inner wall of the slide rail groove, reducing the friction force and the friction loss.

[0015] By providing a scraping plate, a channel plate, a channel support and a guardrail, the present utility model can scrape the attachments on the gate plate when the gate plate rises, and allow maintenance personnel to walk and stand on the channel, making the inspection and observation work of the inspection personnel more convenient.

Specific implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 5, the present utility model provides a technical solution: a water conservancy project flow-blocking device, including a gate body 1, and further including a scraping plate 2 installed on the gate body 1. The lower side of the scraping plate 2 is an arc surface. When the gate plate rises, the shear force generated between the side surface of the scraping plate 2 and the gate plate will scrape and clean the sundries attached to the surface of the gate plate. A lifting frame 3 is fixedly installed on the upper surface of the scraping plate 2. The lifting frame 3 is composed of two screw rods and fixed bases at both ends of the screw rods. The fixed frames at the upper ends of the two screw rods are installed on the gate body 1. The two screw rods and the gate body 1 are rotationally connected. The tops of the two screw rods are fixedly connected with a power source. A ball box 4 is rollingly connected to the lifting frame 3. The ball box 4 is fixedly connected with a slide rail groove 5. The power source drives the two screw rods to rotate, and the ball box 4 drives the slide rail groove 5 to move up and down. 20 groups of slide rails are fixedly arranged in the slide rail groove 5. One side of the slide rail groove 5 is provided with a detector 6. The detector 6 is rotationally connected with 16 groups of pulleys. The 16 groups of pulleys are fixedly connected with a power source. The 16 groups of pulleys roll on the 20 groups of slide rails in the pulley groove 5 under the drive of the power source, thereby driving the horizontal movement of the detector 6. The detector 6 is fixedly connected with a side empty cylinder 7. An impact hammer 8 is in sliding contact with the inner wall of the side empty cylinder 7. There is a rectangular aperture on the side of the side empty cylinder 7 to prevent the impact hammer 8 from losing kinetic energy due to the resistance of the atmospheric pressure when sliding in the side empty cylinder 7. The impact hammer 8 is fixedly connected with 9 groups of springs. The 9 groups of springs can store energy for the translation of the impact hammer 8. The 9 groups of springs are fixedly connected with a spring support 10. The spring support 10 is fixedly installed on the side empty cylinder 7. The side empty cylinder 7 is also rotationally connected with a gear rod 14. A gear structure is arranged on the gear rod 14. One end of the gear rod 14 is fixedly connected with a power source. A cam 15 is fixedly installed on the gear rod 14. The cam 15 rotates under the drive of the gear rod and presses the connecting rod at the bottom end of the impact hammer 8. The detector 6 is also fixedly connected with a receiving rod 11. The receiving rod 11 is in sliding contact with a receiving cylinder 12. A rack is arranged on the lower side of the receiving cylinder 12. When the gear rod 14 rotates, it will drive the receiving cylinder 12 to move through the rack. The receiving cylinder 12 is fixedly connected with a receiving port 13. When the gear rod 14 rotates one week, one end of the receiving port 13 will contact the gate plate. At the same time, the maximum outer diameter of the cam 15 is separated from the connecting rod at the bottom end of the impact hammer 8. The impact hammer 8 is released and strikes the gate plate to generate an impact elastic wave.

[0024] Please refer to Figure 3 , a channel support 17 is fixedly installed on the gate body 1. A channel plate 18 is fixedly installed on the channel support 17. The channel support 17, the channel plate 18 and the side surface of the gate body 1 form a multi-triangle structure. Multiple force points share the pressure, which can provide a stable supporting force. A guardrail 19 is fixedly installed on the channel plate 18. The guardrail 19 is used to protect the personal safety of the staff.

[0025] Please refer to Figure 5, since the detector 6 is on the side of the slide rail groove 5 and the detector 6 generates a vertically downward gravity, we design the 16 sets of pulleys into two pairs of pulleys and the 20 sets of slide rails into two slide rails. Moreover, the slide rail and a pair of pulleys far from the detector 6 are positioned higher, mainly for balancing the gravity of the detector 6, and the slide rail and a pair of pulleys close to the detector 6 are positioned lower, serving as a balance lever force. In this way, the three force application points reach a balanced state, and the two pairs of pulleys and slide rails can keep the force application direction in the vertical direction, avoiding the inclination of the 16 sets of pulleys or the friction damage between their sides and the slide rail groove 5, and maintaining the stable movement of the detector 6.

[0026] Working principle: During the rising process of the gate plate, the shear force between the side of the scraping plate 2 and the gate plate first scrapes off the sundries attached to the gate plate. When the gate plate rises to the top, the power source of the switch lifting frame 3 drives the screw rod to rotate to adjust the lifting of the ball box 4 and the slide rail groove 5. The power source of the switch 16 sets of pulleys controls the 16 sets of pulleys to roll on the 20 sets of slide rails in the slide rail groove 5, thereby controlling the translation of the detector 6. The power source connected to one end of the switch gear lever 14 drives the gear lever 14 to rotate. The gear arranged on the gear lever 14 will drive the receiving cylinder 12 to translate through the rack, thereby driving the receiving port 13 to translate towards the surface of the gate plate. At the same time, the gear lever 14 drives the cam 15 to rotate. The cam 15 squeezes the impact hammer 8 to translate and stretches the 9 sets of springs to store energy for the impact hammer 8. When the gear lever 14 rotates one week, the receiving port 13 contacts the surface of the gate plate, and the maximum outer diameter of the cam 15 separates from the bottom end of the impact hammer 8. The 9 sets of springs contract to drive the impact hammer 8 to reset and strike the surface of the gate plate. Maintenance staff can also operate the control device on the channel plate 18 and observe whether there are defects on the surface of the gate body.
