Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically a steel gate with a spiral lifting transmission mechanism. Background Technology

[0002] Gates are control facilities used to close and open water discharge channels. They are an important component of hydraulic structures and can be used to intercept water flow, control water levels, regulate flow, and discharge sediment and floating debris.

[0003] Existing steel gates are directly installed inside the gate opening. When there is no drainage, the pressure on the steel gate is relatively stable. However, when it is necessary to open the gate to release water, the turbulent water flow will continuously impact the steel gate, increasing the pressure on the steel gate. This can cause the connection between the steel gate and the gate frame to loosen, the gaps to widen, or even cause the steel gate to deform and be damaged, thus affecting the normal use of the steel gate. This utility model designs a steel gate with a spiral lifting transmission mechanism to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 A steel gate with a helical lifting transmission mechanism, comprising:

[0026] A gate frame 1 is provided, and a gate 2 is slidably connected to the inner cavity of the gate frame 1. The gate 2 is controlled by a drive mechanism. A pressure reducing mechanism 5 is fixedly connected to one side of the gate 2. The pressure reducing mechanism 5 includes a reinforcing plate 501 fixedly connected to one side of the gate 2. A connecting frame 502 is provided on one side of the reinforcing plate 501. A pressure reducing plate 503 is rotatably connected to both ends of the connecting frame 502. The end of the pressure reducing plate 503 away from the connecting frame 502 is connected to the reinforcing plate 501 through a limiting mechanism. A groove 504 is provided through one side of both the pressure reducing plate 503 and the reinforcing plate 501. A U-shaped seat 1 505 is slidably connected to the inner cavity of the groove 504. The U-shaped seat 1 505 is driven by a control mechanism. A connecting plate 506 is rotatably connected to the inner cavity of the U-shaped seat 1 505. A U-shaped seat 2 507 is fixedly connected to the middle of one side of the connecting frame 502. A movable groove 508 is provided through both ends of the U-shaped seat 2 507. A limiting shaft 509 is slidably connected to the inner cavity of the movable groove 508.

[0027] The inner wall of the gate frame 1 is provided with a limiting groove 3, and the inner cavity of the limiting groove 3 is slidably connected to a limiting block 4. The limiting block 4 is fixedly connected to the gate 2. The connecting plate 506 is connected to the inner cavity of the U-shaped seat 507 through the limiting shaft 509. The limiting groove 3 and the limiting block 4 are used to improve the stability of the gate 2 during the up and down movement process.

[0028] Please refer to Figure 5 The limiting mechanism includes four limiting grooves 5010 formed on one side of the reinforcing plate 501. The inner cavity of the limiting groove 5010 is slidably connected to the limiting block 5011. The inner cavity of the limiting groove 5010 is fixedly connected to the limiting rod 5012. The limiting block 5011 and the pressure reducing plate 503 are rotatably connected. The limiting rod 5012 passes through the limiting block 5011 and the two are slidably connected.

[0029] In this embodiment of the utility model, when the movable connecting frame 502 is moved, the pressure reducing plate 503 is limited to rotate. This ensures that when the connecting frame 502 moves away from the reinforcing plate 501, the pressure reducing plate 503 can rotate to form a guide slope with an approximately isosceles triangular cross section with the reinforcing plate 501, thereby achieving the purpose of limiting and stabilizing the rotation of the pressure reducing plate 503, which facilitates the stable guidance of the water flow when the gate is opened.

[0030] Please refer to Figure 2 The drive mechanism includes two lead screws 6 fixedly connected to the top of the gate 2. The top of the gate frame 1 is symmetrically and rotatably connected to a threaded cylinder 7. The lead screws 6 pass through the threaded cylinder 7 and the two are threadedly connected. The outer ring of the threaded cylinder 7 is fixedly connected to a worm gear 8, and the outer ring of the worm gear 8 is provided with a worm 9.

[0031] The worm gear 9 is mounted on the top of the gate frame 1 via the drive shaft 10. The drive shaft 10 is rotatably connected to the top of the gate frame 1 via the mounting block 11. A servo motor 12 is fixedly connected to the top of the gate frame 1. The output shaft of the servo motor 12 is fixedly connected to the drive shaft 10. A cover 18 is bolted to the top of the gate frame 1.

[0032] In this embodiment of the utility model, the servo motor 12, in conjunction with the mounting block 11, can drive the worm gear 9 outside the drive shaft 10 to rotate, which in turn drives the threaded cylinder 7 to rotate under the action of the worm wheel 8, thereby driving the lead screw 6 to move upward, so that the gate 2 moves upward under the action of the limiting groove 3 and the limiting block 4 to open the gate, and vice versa to close the gate. The cover 18 protects the entire structure of the drive mechanism, preventing the structural components from aging faster due to wind and sun exposure, and improving the service life of this steel gate with a spiral lifting transmission mechanism.

[0033] Please refer to Figure 2 and Figure 3 The control mechanism includes a fixed cylinder 13 that runs through and is fixedly connected to the inner cavity of the gate frame 1. A control column 14 is slidably connected to the inner cavity of the fixed cylinder 13. A spring 15 is provided in the inner cavity of the fixed cylinder 13. A stabilizing frame 16 is fixedly connected to the inner cavity of the gate frame 1. A guide cylinder 17 is fixedly connected to the top of the gate 2.

[0034] The top and bottom of the spring 15 are fixedly connected to the fixed cylinder 13 and the control column 14 respectively. The control column 14 penetrates into the inner cavity of the groove 504 and is slidably connected to the gate 2. The control column 14 is fixedly connected to the U-shaped seat 505. The control column 14 penetrates the stabilizing frame 16 and the guide cylinder 17 and is slidably connected.

[0035] In this embodiment of the present invention, when the gate 2 is opened to release water, the control column 14 is inserted into the groove 504. During this process, the U-shaped seat 505 moves downward relative to the gate 2, thereby allowing the pressure reducing mechanism 5 to unfold. When the water flow is guided by the pressure reducing plate 503, the water flow will generate an impact force on the pressure reducing plate 503. At this time, the connecting frame 502 will have a force towards the reinforcing plate 501, and this force will eventually cause the U-shaped seat 505 to move upward, thereby causing the control column 14 to move upward and compress the spring 15 in the fixing cylinder 13, thereby weakening the impact force of the water flow on the pressure reducing plate 503 and preventing the pressure reducing plate 503 from being damaged by the water flow impact.

[0036] In use, after the gate frame 1 is installed in the required position, when the water source is blocked by the gate 2, the pressure of the water on the gate 2 causes the pressure reducing plate 503 to adhere to the reinforcing plate 501. The reinforcing plate 501 and the pressure reducing plate 503 increase the strength of the gate 2. When the gate 2 is moved upward to open the gate and release water, the control column 14 in the control mechanism limits the U-shaped seat 505. During the upward movement of the gate 2, in conjunction with the connecting plate 506 and the limiting shaft 509 in the movable groove 508, the connecting frame 502 moves away from the reinforcing plate 501. Under the limitation of the limiting mechanism, the pressure reducing plate 503 rotatably connected on both sides of the connecting frame 502 will rotate, forming a guide slope with the reinforcing plate 501 with an approximately isosceles triangular cross section. This guides the water flow when the gate is opened and released, thereby reducing the pressure of the water flow on the gate 2, that is, reducing the pressure at the connection between the gate 2 and the gate frame 1, and improving the service life of this steel gate with a spiral lifting transmission mechanism.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
