The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.
[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0030] As described in the background section, although screw drives offer good precision, they require a greater number of screw rotations to move the gate a certain distance, resulting in slower gate movement and lower transmission efficiency. While chain drives can increase gate speed, they also generate significant noise during operation due to the collision between the chain and sprockets.
[0031] Reference Figure 1 As shown, a belt-driven integrated measurement and control gate according to an embodiment of the present invention includes a frame 100, a gate plate 200 and a driving device 300.
[0032] The gate 200 is slidably connected to the frame 100 and can move along a first direction, wherein the first direction is parallel to the plate surface of the gate 200, and the gate 200 and the frame 100 together form a flow channel with a variable cross-sectional area; the drive device 300 is connected to the gate 200 by a toothed belt 310 and can drive the gate 200 to move along the first direction.
[0033] In the belt-driven integrated measurement and control gate, the gate plate 200 is mainly used to block the water flow. Therefore, the moving direction of the gate plate 200 needs to be parallel to the surface of the gate plate 200, that is, the first direction is parallel to the surface of the gate plate 200. Generally, the first direction is vertical, that is, the frame 100 is set in a vertical plane. In this structure, the flow channel formed by the gate plate 200 and the frame 100 is located in the lower part of the frame 100. That is, when the gate plate 200 moves up along the first direction, the flow channel below the gate plate 200 is opened, and as the gate plate 200 gradually moves up, the cross-sectional area of the flow channel gradually increases, and the theoretical flow rate of the water can gradually increase.
[0034] The drive unit 300 drives the movement of the gate 200 via the toothed belt 310. The drive unit 300 can be powered by an electric motor, and the transmission function is achieved by the meshing of the teeth of the transmission component with the teeth of the toothed belt 310.
[0035] For example, refer to Figure 2 As shown, it can be understood that the drive device 300 includes a transmission gear 320 and a strip-shaped mounting member 330. The mounting member 330 is parallel to the first direction. One end of the mounting member 330 is fixedly connected to the gate plate 200. A toothed belt 310 is disposed on the mounting member 330, and both ends of the toothed belt 310 are respectively fixed to both ends of the mounting member 330. The transmission gear 320 meshes with the toothed belt 310.
[0036] The toothed belt 310 has its two ends fixed to the two ends of the mounting member 330, forming a single unit. When the transmission gear 320 meshes with the toothed belt 310, driving the toothed belt 310 to move, the mounting member 330 moves along with the toothed belt 310. Specifically, the mounting member 330 is fixedly connected to the gate plate 200, meaning the toothed belt 310 and the gate plate 200 are connected via the mounting member 330. The mounting member 330 maintains the shape of the toothed belt 310 and serves to transmit force.
[0037] It's important to understand that compared to chain drives, toothed belt drives (310) generate significantly less noise and are also less expensive. Furthermore, toothed belt drives (310) offer faster transmission speeds compared to screw drives (310).
[0038] It is understood that it also includes a limiting mechanism 400, which is located on one side of the transmission gear 320. The limiting mechanism 400 abuts against the toothed belt 310 and can limit the part of the toothed belt 310 that is not engaged with the transmission gear 320 from contacting the mounting part 330.
[0039] The function of the limiting mechanism 400 is to keep the unengaged portion of the toothed belt 310 as close as possible to the mounting member 330. Although the tension of the toothed belt 310 can be adjusted to keep it close to the mounting member 330, at the point where the toothed belt 310 engages with the transmission gear 320, it will move away from the mounting member 330, forming a triangular structure. Specifically, the point where the toothed belt 310 engages with the transmission gear 320, and the two ends of the toothed belt 310 together form the three vertices of the triangle. By adding the limiting mechanism 400, especially by placing the limiting mechanism 400 on one side of the transmission gear 320, the portion of the toothed belt 310 that has left the transmission gear 320 can be kept close to the mounting member 330, avoiding the formation of the aforementioned triangular structure and reducing the risk of the toothed belt 310 detaching from the transmission gear 320.
[0040] Reference Figure 2 As shown, it can be understood that the limiting mechanism 400 includes a first limiting wheel 410 and a second limiting wheel 420. The first limiting wheel 410 and the second limiting wheel 420 are symmetrically distributed on both sides of the transmission gear 320, with the transmission gear 320 as the center of symmetry. The toothed belt 310 passes around the first limiting wheel 410 and the second limiting wheel 420 and meshes with the transmission gear 320, so that the toothless surface of the toothed belt 310 contacts the first limiting wheel 410 and the second limiting wheel 420, and the toothed surface of the toothed belt 310 contacts the transmission gear 320.
[0041] When the frame 100 is in a vertical position, the first limiting wheel 410 is positioned above the transmission gear 320, and the second limiting wheel 420 is positioned below the transmission gear 320. Taking the rotation of the transmission gear 320 driving the toothed belt 310 to move upward as an example, after the upper part of the toothed belt 310 leaves the transmission gear 320, it is immediately guided by the first limiting wheel 410 and comes into contact with the mounting piece 330. Similarly, the lower part of the toothed belt 310 is first guided by the second limiting wheel 420 before moving to engage with the transmission gear 320.
[0042] Reference Figure 3 As shown, it can be understood that the drive device 300 includes a pair of transmission gears 320 and two mounting members 330. The two mounting members 330 are symmetrically distributed and their axis of symmetry is parallel to the first direction. The two transmission gears 320 are connected to a transmission shaft 340. The two transmission gears 320 are located at both ends of the transmission shaft 340. Each transmission gear 320 meshes with a toothed belt 310. The transmission shaft 340 is connected to a motor 350, which can drive the transmission shaft 340 to rotate.
[0043] The motor 350 drives two transmission gears 320 to rotate in the same direction simultaneously via the transmission shaft 340, thereby driving the two mounting parts 330 to move in the same direction, which can improve the smoothness of the movement of the gate 200. It should be understood that the motor 350 and the transmission shaft 340 can adopt a bevel gear transmission to ensure that the transmission gears 320 at both ends of the transmission shaft 340 can rotate in the same direction.
[0044] It is understandable that the mounting component 330 has a strip groove 331, which is parallel to the first direction, and the toothed belt 310 is disposed in the strip groove 331.
[0045] The toothed belt 310 can be constrained by the slot 331 within the slot 331, maintaining a parallel orientation to the first direction. The slot 331 constrains the toothed belt 310, reducing the risk of it disengaging from the transmission gear 320 due to deflection.
[0046] It is understood that one end of the mounting component 330 is provided with an adjustment mechanism 500, and the end of the toothed belt 310 is connected to the adjustment mechanism 500. The adjustment mechanism 500 can move the end of the toothed belt 310 parallel to the first direction to change the tension of the toothed belt 310.
[0047] By pulling the end of the toothed belt 310 parallel to the first direction, the adjustment mechanism 500 can change the tension of the toothed belt 310. For example, by pulling the end of the toothed belt 310 away from the other end of the toothed belt 310, the adjustment mechanism 500 can increase the tension of the toothed belt 310 to ensure stable meshing between the toothed belt 310 and the transmission gear 320.
[0048] Reference Figure 4 As shown, it can be understood that the adjusting mechanism 500 includes a pull rod 510 and a fixing block 520. The end of the toothed belt 310 is fixed to the fixing block 520. The fixing block 520 is connected to the pull rod 510. The pull rod 510 is parallel to the first direction. The pull rod 510 passes through the mounting member 330 and can move parallel to the first direction. The pull rod 510 is fitted with a plurality of locking nuts, which can limit the relative position between the pull rod 510 and the mounting member 330.
[0049] The pull rod 510 is movable. By moving the pull rod 510, the fixed block 520 is moved, thereby moving the end of the toothed belt 310 to adjust the tension of the toothed belt 310. For example, by adjusting the locking nut on the pull rod 510 so that the locking nut is away from the mounting part 330, space is reserved for the pull rod 510 to move. After the pull rod 510 is moved to the designated position, the locking nut is screwed onto the mounting part 330 to abut against it. At this time, the pull rod 510 will not be able to move, thus fixing the position between the pull rod 510 and the mounting part 330, that is, the tension of the toothed belt 310 is determined.
[0050] Reference Figure 5 As shown, it can be understood that guide grooves 101 are provided on both sides of the frame 100. The guide grooves 101 are parallel to the first direction. The two sides of the gate 200 are respectively set in the guide grooves 101, so that the gate 200 can move along the guide grooves 101.
[0051] The guide groove 101 guides the movement of the gate 200, allowing it to move more smoothly along the first direction. Simultaneously, when the gate 200 is subjected to water pressure, the guide groove 101 also supports it, providing a perpendicular support force to the gate surface.
[0052] It is understandable that the guide groove 101 has a sealing strip on its groove wall, the sealing strip is parallel to the first direction, and the sealing strip is in contact with the plate surface of the gate 200.
[0053] The sealing strip can improve the sealing performance of the contact area between the gate 200 and the guide groove 101, and reduce the possibility of water leakage between the gate 200 and the guide groove 101.
[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
