Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy engineering, and in particular to a rotary interception device for water conservancy construction. Background Technology

[0002] Water conservancy refers to the activities of controlling, regulating, guiding, developing, managing and protecting water in nature through various artificial measures, in order to mitigate and avoid floods and droughts, and to utilize water resources to meet human production and living needs.

[0003] In the process of water conservancy construction, it is often necessary to use interception devices to block the water flow. However, some interception is done by blocking from both the top and bottom. At this time, the water flow will generate impact force, which can easily splash water. Moreover, if the impact force is too large, it will cause the interception device to break, affecting the interception effect. In order to solve the above problems, we have made improvements and proposed a rotary interception device for water conservancy construction. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] This utility model provides a technical solution, such as Figures 1-4 As shown; a rotary hydraulic construction interception device includes: a water flow channel 1, which is supported by sand and gravel 11 below, and the surface of the channel is a concrete structure 12; the water flow channel 1, which is supported by sand and gravel 11 and formed by the concrete structure 12, can effectively ensure the stability of its shape and avoid deformation of the water flow channel 1 due to external forces, thereby ensuring the integrity of the interception gate 5 and the sealing bottom frame 3, so that it can smoothly carry out the interception work.

[0030] The fixed base 2 is installed on both sides of the water flow channel 1 and anchored by anchor bolts 21. It is L-shaped. The sealing bottom frame 3 is installed on the inner lower surface of the water flow channel 1 and matches the shape of the inner wall of the water flow channel 1. Both ends are connected to the fixed base 2. Its cross-section is right-angled. A sealing pad 31 is set below it and a compression pad 32 is set on its inner vertical surface.

[0031] In this embodiment of the utility model, the fixed base 1 can be installed on both sides of the water flow channel 1, which facilitates the fixing of the sealing bottom frame 3. The fixed base 1 can apply downward pressure to the sealing bottom frame 3 by connecting with it, thereby ensuring the firmness of the sealing bottom frame 3 installation.

[0032] In this embodiment of the utility model, the sealing bottom frame 3 has a right-angled cross-section, which allows it to fit snugly against the lower end of the flow-blocking gate 5, thereby ensuring the smooth flow-blocking of the water channel 1. At the same time, the sealing pad 31 ensures the seal between the sealing bottom frame 3 and the water channel. The compression pad 32 allows the flow-blocking gate 5 to compress the sealing bottom frame 3 for sealing, preventing water leakage and ensuring the smooth flow-blocking of the water.

[0033] A rotating shaft 4 is horizontally positioned above the water flow channel 1, with both ends connected to the fixed base 2 via bearings. A flow-stopping gate 5 is vertically positioned inside the water flow channel 1, below the rotating shaft 4, and in contact with the compression pad 32 on the vertical surface of the sealing base frame 3. Connecting rods 51 are evenly arranged above the gate, and fixing rings 52 are installed on the connecting rods 51. The fixing rings 52 are fixedly fitted onto the rotating shaft 4. A worm gear reducer 6 is installed on one of the fixed bases 2, with a drive motor 61 installed at its input end and a coupling 62 installed at its output end. The coupling 62 is connected to one end of the rotating shaft 4.

[0034] In this embodiment of the utility model, the drive motor 61 drives the worm gear reducer 6 to rotate the rotating shaft 4, which in turn drives the flow cut-off gate 5 to rotate, thereby controlling the flow of water in the water channel 1 and cutting off the flow, which effectively facilitates the operation and use of the staff.

[0035] In this embodiment of the utility model, by utilizing the worm gear reducer 6, the self-locking property of its transmission can be used to enable the dam 5 to effectively withstand the impact force of the water flow during the damming process, preventing the water flow from impacting the dam 5 and causing the dam 5 to rotate too fast and hit the sealing bottom frame 3, thereby ensuring the safety of the device and effectively improving its service life.

[0036] In this utility model, several square fastening seats 13 are embedded on the upper surface of the concrete structure 12 of the water flow channel 1. The upper end of the square fastening seats 13 has a threaded hole. The square fastening seats 13 are evenly distributed on the lower side of the sealing bottom frame 3. The sealing bottom frame 3 is fastened to the water flow channel 1 by fastening bolts 33 and the square fastening seats 13 through threaded connection. This makes the sealing bottom frame 3 and the water flow channel 1 more firmly fixed, thereby ensuring that its installation is firm and airtight.

[0037] In this utility model, when the intercepting gate 5 cuts off the water flow channel 1, the sealing bottom frame 3 is attached to the outer side of the lower end of the intercepting gate 5; so that the intercepting gate 5 can fully squeeze the sealing bottom frame 3 to ensure the smooth cut-off of the water flow and avoid water leakage.

[0038] In this utility model, when the sealing bottom frame 3 is attached to the outer side of the lower end of the throttling gate 5, the lower end of the throttling gate 5 is spaced a certain distance from the inner lower surface of the sealing bottom frame 3; this allows the throttling gate 5 to rotate smoothly and ensures that the water can flow out quickly when the throttling gate 5 is opened.

[0039] In this invention, the shape of the intercepting gate 5 matches the shape of the inner wall of the water flow channel 1, ensuring that the intercepting gate 5 can cooperate with the sealing bottom frame 3 to intercept the flow.

[0040] In this invention, a triangular reinforcing seat 34 is provided on the outer side of the vertical surface of the sealing base frame 3, and the triangular reinforcing seat 34 is located above the sealing pad 31; this improves the strength of the vertical surface of the sealing base frame 3, ensures the strength of the device, and prevents water leakage after the flow is cut off.

[0041] When using this utility model, the staff installs the device into the water flow channel 1. When it is necessary to cut off the flow, the staff controls the drive motor 61 to work, so that it drives the rotating shaft 4 to rotate through the worm gear reducer 61. Then, the rotating shaft 4 drives the cut-off gate 5 to rotate, so that the cut-off gate 5 rotates towards the inside of the water flow channel 1.

[0042] As the dam 5 gradually rotates into the water flow channel 1, the dam 5 comes into contact with the water flow, and the self-locking property of the worm gear reducer 61 enables it to withstand the impact of the water flow, and it continues to rotate as the drive motor 61 works.

[0043] As the dam 5 gradually rotates to a vertical position, the vertical surface of the sealing base frame 3 approaches the lower outer side of the dam 5. Then, by continuing to rotate the dam 5, the dam 5 presses against the sealing base frame 3. Furthermore, by pressing the dam 5 against the compression pad 32, the dam 5 and the sealing base frame 3 are sealed, thus completing the water flow cutoff operation.

[0044] When water needs to be released, the drive motor 61 is controlled to work in reverse, which in turn drives the rotating shaft 4 to rotate in the opposite direction using the worm gear reducer 61. This causes the intercepting gate 5 to rotate outward from the water flow channel 1, gradually creating and widening a gap between the intercepting gate 5 and the sealing base frame 3, allowing the water to drain quickly. As the intercepting gate 5 continues to rotate, the drainage space between the intercepting gate 5 and the sealing base frame 3 gradually increases until the intercepting gate 5 separates from the water flow. Once the intercepting gate 5 rotates to a horizontal position, the drive motor 61 is stopped.

[0045] In a specific implementation of this utility model, a limiting device can be set at one end of the rotating shaft 4 to reduce the rotation angle to 90°, thereby avoiding excessive pressure on the sealing bottom frame 3 by the throttling gate 5, which could cause deformation and ensure the tightness of the device's throttling.
