[0003] The bottom shaft of the existing bottom shaft rotation type steel gate is arranged at the bottom of the door body, and the bottom shaft is installed on the fixing device of the river bottom sill. The bottom shaft is driven to rotate by the driving device, and the door body is driven to rotate, so as to realize the water blocking of the door body or the water release of the door body. There is a gap between the door body and the fixing device, so a seal is needed to stop water when the door body is upright to block water, and no seal is needed to stop water when the door body is laid down to release water. For this purpose, the conventional measure is to set a water stop rubber at the bottom of the door body, and the compression amount of the water stop rubber remains relatively constant during the movement of the door body. The defects are: first, when the door body does not need to block water, the water stop rubber is still compressed, which will affect its service life; second, if the compression amount of the water stop rubber is too large, its service life will be reduced, and the water stop rubber will be turned over during the fitting operation, affecting the water stop effect, and if the compression amount of the water stop rubber is too small, it is easy to produce gap, resulting in water leakage or jamming of sundries.

[0048] In order to make the objects, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0049] Therefore, the detailed description herein of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present application.

[0050] It should be noted that similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, all directional indications (such as up, down, left, right, front, back, bottom, etc.) in this application are only used to explain the relative positional relationships and movements between components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indication will also change accordingly. Furthermore, descriptions involving "first," "second," etc., in this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0051] Example 1:

[0052] like Figures 1 to 8 As shown, this embodiment provides a water-stopping device for a bottom-shaft rotating steel gate, which includes a gate assembly, a bottom shaft, a drive device (not shown), and a water-stopping fitting device.

[0053] In this embodiment, the gate assembly includes a gate body and a water-stopping component located at the bottom of the gate body. It should be noted that in other embodiments, the water-stopping component may not be provided at the bottom of the gate body, thus achieving water stoppage through the gate body itself in conjunction with other components.

[0054] Specifically, the water-stop fitting device is fixed to the bottom sill of the river channel, the bottom shaft passes through the water-stop fitting device, and the bottom shaft can rotate about the rotation center relative to the water-stop fitting device. Figure 2 The rotation center is shown. The door body and the bottom shaft are fixedly connected. The bottom shaft and the door body can be produced as a whole, or they can be produced in sections and assembled on-site according to actual conditions. The drive device can drive the bottom shaft to rotate, thereby causing the door body 1 to rotate from a lying position along the first rotation direction A to an upright position, or from an upright position along the second rotation direction B to a lying position. Figure 2 The first rotation direction A and the second rotation direction B are shown.

[0055] Since the water-stop fitting device remains fixed, while the door body needs to rotate with the bottom shaft, a certain gap needs to be left between the door body and the water-stop fitting device to ensure relative rotation between them. Furthermore, a water-stop structure needs to be installed at this location to ensure that the door body and the water-stop fitting device can contact and stop the water when the door body is in the upright position. Therefore, in this embodiment, the water-stop fitting device is configured to include an arc-shaped reference surface corresponding to the door body's rotation area, and a protrusion corresponding to the door body's rotation area. The distance from the upper surface of the protrusion to the rotation center is greater than the distance from the arc-shaped reference surface to the rotation center.

[0056] It should be noted that the arc-shaped reference surface and the convex portion in the present patent refer to the area corresponding to the rotation range of the door body. For example, when the rotation range of the door body is 90°, the arc-shaped reference surface and the convex portion are also correspondingly located at the position of the water stop cooperation device corresponding to the 90° range, and other positions of the water stop cooperation device do not need to consider whether to be provided with a water stop structure, and the arc-shaped reference surface or the convex portion is not involved.

[0057] In the present embodiment, the convex portion is integrally formed with the water stop cooperation device. Specifically, in the processing process, the convex portion can be formed by protruding the surface of the water stop cooperation device away from the rotation center. In other embodiments, the convex portion can also be provided in other forms, as long as the distance from the upper surface of the convex portion to the rotation center is greater than the distance from the arc-shaped reference surface to the rotation center.

[0058] Further, as for the convex portion, in the present embodiment, the upper surface thereof includes two parts. The distance from the upper surface of one part of the convex portion to the rotation center gradually increases along the first rotation direction, and the distance from the upper surface of the other part of the convex portion to the rotation center remains stable along the first rotation direction.

[0059] The water stop device of the bottom shaft rotating steel gate provided in the present embodiment is such that when the door body rotates along the first rotation direction A, the water stop member rotates along the surface of the water stop cooperation device under the driving of the door body. When it rotates to the opposite side of the arc-shaped reference surface, the water stop member does not contact the arc-shaped reference surface for water stop due to the small distance from the arc-shaped reference surface to the rotation center. When it rotates to the opposite side of the convex portion, the water stop member contacts the convex portion, thereby realizing water stop in this area. Moreover, for the convex portion with varying distance to the rotation center, when the water stop member rotates to this area, the compression amount of the water stop member gradually increases under the action of the convex portion. For the convex portion with stable distance to the rotation center, when the water stop member rotates to this area, the compression amount of the water stop member remains relatively stable until the door body rotates to the upright position.

[0060] Such a structure design is such that, first, when the door body is located at a position not requiring water stop, the water stop member is not compressed, and when the door body is located at a position requiring water stop such as the upright position, the water stop member has a suitable compression amount, that is, the sealing water stop effect of the water stop member matches the water stop requirement when the door body is at different positions, thereby improving the service life of the water stop member under the premise of ensuring the water stop effect. Second, by making the distance from part of the upper surface of the convex portion to the rotation center vary and the distance from part of the upper surface to the rotation center remain stable, the water stop member can be continuously compressed in the process of upward rotation of the door body, and at the same time, such a structure design also avoids the overturning of the water stop member, thereby improving the service life of the water stop member while ensuring the sealing performance. Third, since the volume of the water stop cooperation device is small, the processing is convenient.

[0061] Furthermore, in this embodiment, side water-stopping parts are also provided on both sides of the water-stopping device. The side water-stopping parts are provided in correspondence with the protrusions. That is, in this embodiment, the area between the door body and the water-stopping device is set as a three-sided water-stopping area.

[0062] Furthermore, in this embodiment, there are two drive devices. A gate operating chamber (not shown) is provided on each side of the gate body, and the drive devices are respectively housed within the chambers. The drive devices drive the bottom shaft to rotate, thereby rotating the gate body to either an upright or a horizontal position. Regarding the specific driving method of the drive devices, they can be directly connected to the bottom shaft and drive its rotation, or a crank arm (not shown) or similar structure can be fixed to the bottom shaft and the drive device connected to the crank arm, allowing the drive device to drive the bottom shaft to rotate via the crank arm. As for the specific form of the drive devices, those skilled in the art can select according to actual needs and can make conventional and reasonable settings based on the actual structure; for example, the drive device can be a hydraulic cylinder. It should be noted that in this embodiment, the drive devices are respectively housed in the gate operating chambers on both sides of the gate body, while in other embodiments, only one drive device and one gate operating chamber may be provided depending on the actual situation.

[0063] Example 2:

[0064] like Figures 9 to 10 As shown, this embodiment provides a water-stopping device for a bottom-shaft rotating steel gate, which has a structure that is roughly the same as the water-stopping device for a bottom-shaft rotating steel gate provided in the first embodiment. The difference is that in the first embodiment, the protrusion and the water-stopping device are integrally set, while in this embodiment, the protrusion and the water-stopping device are processed separately and fixedly connected.

[0065] Example 3:

[0066] like Figure 11 As shown, this embodiment provides a water-stopping device for a bottom-shaft rotating steel gate, which has a structure largely the same as the water-stopping device for a bottom-shaft rotating steel gate provided in the first embodiment. The difference is that in the first embodiment, a water-stopping component is provided at the bottom of the gate body. In this embodiment, however, no water-stopping component is provided at the bottom of the gate body, and the protrusion is made of rubber. Water stoppage is achieved when the bottom of the gate body contacts the protrusion.

[0067] The specific embodiments of this utility model have been described above. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this invention.
