Description

Technical Field

[0001] The present invention relates to the technical field of sluice gates, in particular to a sluice gate segmented water intake device. Background Art

[0002] A sluice gate refers to a low-head hydraulic structure built on rivers and channels that uses gates to control flow and regulate water levels. Closing the gates can block floods, tides or raise upstream water levels to meet the needs of irrigation, power generation, shipping, aquaculture, environmental protection, industry and domestic water use. Opening the gates can discharge floods, waterlogging, abandoned water or wastewater, and can also supply water to downstream rivers or channels. In water conservancy projects, sluice gates are widely used as structures for retaining, discharging or taking water. The sluice gate segmented water intake device can take segmented water from one side of the gate for testing or daily use.

[0003] In the field of water conservancy projects, dams are often built to manage water. Dams are composed of multiple sluice piers and gates. When the downstream of the river needs water, the gates are often opened, and then the water from the upstream flows downstream through the gates. During the operation of the gates, floating objects such as trees or obstacles such as stones are carried to the bottom of the gate by the high-speed water flow or rushed into the gate slot and stuck. If the gate is closed at this time, there will be no prompt that it is in place, and it is easy to cause a gate-pushing accident, which will cause the gate to slide in the gate slot and be damaged, affecting the life of the gate.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1

[0032] See also Figure 1-9 This embodiment provides a sluice segmented water intake device, including gate piers 1, brackets 3 and top material components arranged on both sides of the river channel. The side walls of the gate piers 1 at one end close to each other are fixedly provided with brackets 3, and the inner wall of the brackets 3 is slidably mounted with a gate 2. The top of the gate pier 1 is provided with a lifting structure for controlling the rising and falling of the gate 2. The lifting structure is a screw lift commonly used in this field. The gate 2 can be controlled to rise and fall by the screw lift to facilitate the opening and closing of the gate 2.

[0033] The inner wall of the bracket 3 is provided with a gate groove for the gate 2 to slide, and the outer wall of the gate 2 fits with the inner wall of the gate groove. The opening of the gate groove can provide space for the opening and closing of the gate 2, thereby facilitating the lifting and lowering process of the gate 2.

[0034] The ejecting assembly includes a connecting head 16 and a ejecting head 6 fixedly installed on both sides of the bottom of the gate 2. The connecting head 16 is a conical structure, and the bottom of the conical structure of the connecting head 16 fits with the inner wall of the gate groove. The ejecting head 6 is slidably installed at the bottom of the gate groove. One side of the ejecting head 6 is a wedge-shaped structure, and the outer wall of the ejecting head 6 fits with the bottom inner wall of the gate groove. The conical structure of the connecting head 16 can facilitate the scraping process of the side wall of the gate groove when the gate 2 falls, so as to avoid obstacles remaining inside the gate groove and affecting the falling process of the gate 2.

[0035] A connecting rod 7 is movably installed on one side of the ejecting head 6. The end of the connecting rod 7 away from the ejecting head 6 is rotatably connected to the middle of the connecting head 16. The connecting rod 7 can connect the ejecting head 6 and the connecting head 16. When the gate 2 falls, the falling of the connecting head 16 can drive the connecting rod 7 to press the ejecting head 6 to slide on the inner wall of the gate groove to eject the residual obstacles in the bottom of the gate groove, thereby ensuring the normal falling of the gate 2.

[0036] When the gate 2 is closed, in order to prevent obstacles and floating objects in the water from accumulating inside the gate slot and affecting the closing of the gate 2, and to ensure the normal closing process of the gate 2, the gate 2 can be driven to fall by starting the lifting structure. When the gate 2 falls, the connector 16 at its bottom will also slide downward along the side wall of the gate slot, and the outer wall of the conical structure of the connector 16 can be used to push out obstacles and floating objects accumulated on the side wall of the gate slot, thereby ensuring the normal falling process of the gate 2.

[0037] At the same time, when the connecting head 16 falls, the connecting rod 7 rotatably connected to it can press the ejecting head 6, so that it slides on the bottom inner wall of the gate groove when the connecting rod 7 presses. One end of the inclined structure of the ejecting head 6 can easily eject floating objects and obstacles in the bottom of the gate groove and separate them from the inside of the gate groove under the action of water flow, thereby ensuring the cleanliness of the inside of the gate groove, making the falling and closing of the gate 2 more convenient, and at the same time there will be no problem of pushing the gate, thereby better protecting the gate 2 and extending the service life of the gate 2.

[0038] The specific shapes of the connector 16 and the ejector head 6 can be found in the appendix of the specification. Figure 7 The above-mentioned shape of the connecting head 16 and the ejecting head 6 can better eject obstacles and floating objects during the sliding process on the side wall and bottom of the gate groove, thereby improving the obstacle cleaning effect. At the same time, no new power source is needed when cleaning the inside of the gate groove, making the cleaning process of the inner wall of the gate groove more convenient.

[0039] The ejecting head 6 is located on one side of the bottom of the connecting head 16, and the ejecting head 6 and the connecting head 16 are not in the same plane. The connecting rod 7 is tilted, and one end of the connecting rod 7 is rotatably connected to the middle of the side wall of the ejecting head 6. When the ejecting head 6 and the connecting head 16 are not in the same plane, and the connecting rod 7 is in an inclined state, it can be ensured that the gate 2 falls and drives the connecting head 16 to fall. In the process, the connecting rod 7 and the ejecting head 6 can be pushed to slide on the inner wall of the gate groove to ensure the cleaning effect of the ejecting head 6.

[0040] A cylindrical rotating shaft 18 is fixed to the side wall of the ejecting head 6, and connecting sleeves 19 are fixed at both ends of the connecting rod 7. The middle part of the connecting sleeve 19 is hollowed out, and the connecting sleeve 19 is rotatably installed on the outer wall of the rotating shaft 18. A rotating groove for the connecting sleeve 19 to rotate is provided on the side wall of the ejecting head 6. The opening of the rotating groove can provide space for the rotation of the connecting sleeve 19. Through the setting of the connecting sleeve 19 and the rotating shaft 18, it can be ensured that the connection relationship between one end of the connecting rod 7 and the ejecting head 6 is a rotating connection, so as to ensure that the connecting head 16 can drive the connecting rod 7 to push the ejecting head 6 to slide on the inner wall of the gate groove when falling, and complete the cleaning process.

[0041] The inner diameter of the hollowed-out middle part of the connecting sleeve 19 is not less than the outer diameter of the rotating shaft 18. The rotation center of the connecting sleeve 19 coincides with the axis of the rotating shaft 18. The inner diameter is greater than the outer diameter of the rotating shaft 18, which can ensure that the connecting sleeve 19 can rotate on the outer wall of the rotating shaft 18. When the axis coincides, it can ensure that the rotation direction of the connecting sleeve 19 on the outer wall of the rotating shaft 18 corresponds to the starting position of the rotating groove, so as to ensure that the connecting sleeve 19 can complete the rotation process inside the rotating groove.

[0042] A water tank 20 for storing water at different water levels is provided on one side of the gate 2. There are multiple water tanks 20, which are evenly distributed along the side wall of the gate 2. The water tank 20 is a cylindrical structure. A blocking plate 4 for closing the water tank 20 is rotatably installed on the inner wall of the water tank 20. A driving structure for driving the blocking plate 4 to rotate is fixed on the top of the gate 2. Multiple water tanks 20 are inclined along the middle axis of the side wall of the gate 2, and the distance between two adjacent water tanks 20 is the same.

[0043] The multiple water storage tanks 20 arranged at an angle can correspond to water bodies with different water levels respectively. When taking water for use or sampling and testing, the driving structure is started to drive the blocking plate 4 in the water storage tank 20 to rotate so that water can enter the water storage tank 20, and the water in the water storage tank 20 can be pumped out through the water intake hole 21 to complete the water intake process.

[0044] The driving structure may be a control rod and a motor. The control rod is fixedly connected to the middle of the top side of the blocking plate 4. The motor can be started to drive the control rod to rotate, thereby driving the blocking plate 4 to rotate.

[0045] The setting of the blocking plate 4 can prevent the water on one side of the gate 2 from entering the water tank 20. When the blocking plate 4 rotates, the water can enter the water tank 20 from the gap. The water tanks 20 at different positions can allow water at different water levels to enter the water tank 20 to complete the water extraction process after the blocking plate 4 on the inner wall rotates, thereby making the segmented water extraction process in the water body more convenient, and further facilitating the water body detection and water extraction and use process.

[0046] A water intake hole 21 is provided at the top of the gate 2. There are multiple water intake holes 21, which are evenly distributed on the top of the gate 2, and the bottoms of the water intake holes 21 are respectively connected to the interior of the water storage tanks 20 at different positions. The multiple water intake holes 21 can better correspond to the multiple water storage tanks 20. By utilizing the multiple water intake holes 21, water bodies in different water levels can be pumped out, and at the same time, confusion of the water bodies can be avoided, so that the water intake and use and the subsequent detection process of the water body are more accurate.

[0047] Example 2

[0048] See also Figure 1-9, further improvements are made on the basis of Example 1: the gate 2 is mostly made of metal, but due to the inherent characteristics of the metal material, the gate 2 is immersed in river water for a long time, and rust will inevitably appear on the surface of the gate 2. If the rust is not dealt with in time, it will accelerate the rust damage of the gate 2 and shorten the service life of the gate 2. In order to scrape off the rust on the surface of the gate 2, a cleaning component for cleaning the outer wall of the gate 2 is provided on one side of the gate 1. The cleaning component includes a connecting frame 5, an extension frame 9 and a cleaning plate 8. The cleaning plate 8 is movably installed on one side of the gate 2. The cleaning plate 8 is a prism-shaped structure, and the side wall of one end of the cleaning plate 8 is in contact with the outer wall of the gate 2. The extension frames 9 are respectively installed at both ends of the side walls of the cleaning plate 8. The connecting frame 5 is fixed on one side of the connecting head 16. The extension frame 9 and the connecting frame 5 are L-shaped structures. The interior of the gate 1 is provided with a control structure for driving the extension frame 9 to rise.

[0049] When the gate 2 falls, the extension frame 9 can be driven to rise through the control structure, and the cleaning plate 8 can be driven to slide upward along the outer wall of the gate 2. One end of its prism-shaped structure can be used to scrape off the rust on the surface of the gate 2. At the same time, in actual use, the cleaning plate 8 can also scrape off the residue attached to its surface by sliding along the outer wall of the gate 2 to avoid the accumulation of residue and the corrosion of the gate 2, thereby better protecting the gate 2, preventing the rust of the gate 2 from being delayed, and extending the service life of the gate 2.

[0050] The L-shaped extension frame 9 can better drive the cleaning plate 8 to rise, and at the same time, the use of the cleaning plate 8 will not be hindered during the driving process of the extension frame 9.

[0051] The control structure includes a rotating shaft 15 rotatably installed inside the gate pier 1, a driving wheel 14 is fixed to one side of the rotating shaft 15, a control plate 12 is engaged with the outer wall of one end of the driving wheel 14, and a driven plate 13 is engaged with the outer wall of the other end of the driving wheel 14. One end of the connecting frame 5 extends to the interior of the gate pier 1, and the end of the connecting frame 5 extending to the interior of the gate pier 1 is fixedly connected to the side wall of the control plate 12. One end of the extension frame 9 extends to the interior of the gate pier 1, and the end of the extension frame 9 extending to the interior of the gate pier 1 is fixedly connected to the side wall of the driven plate 13. Guide grooves 10 for the movement of the extension frame 9 and the connecting frame 5 are respectively provided inside the gate pier 1.

[0052] The driven plate 13 and the control plate 12 are racks respectively, and the driving wheel 14 is a gear. When the gate 2 falls, the connecting head 16 will fall at the same time and drive the connecting frame 5 fixed to it to slide downward along the inner wall of the movable groove 11. The sliding process of the connecting frame 5 can drive the control plate 12 to slide downward inside the gate pier 1, and the driving wheel 14 can be rotated by the tooth block on its side wall. When the driving wheel 14 rotates, the tooth block on its outer wall can drive the driven plate 13 to slide upward, thereby driving the extension frame 9 to slide upward and driving the cleaning plate 8 to clean the side wall of the gate 2, so that the rust scraping effect on the outer wall is better.

[0053] Thereby, the rust cleaning process of the outer wall of the gate 2 can be made more convenient, and it can be completed without adding a new power source. The rust on the outer wall of the gate 2 can be scraped off during the raising or lowering process of the gate 2, making the rust cleaning of the gate 2 more convenient.

[0054] In actual use, a bristle brush for cleaning rust can be installed on the side of the cleaning plate 8 close to the gate 2 to achieve a better rust removal effect.

[0055] The width of the guide groove 10 is not less than the width of the connecting frame 5 and the extension frame 9. The driven plate 13 and the control plate 12 are respectively engaged with the gear blocks at both ends of the outer wall of the driving wheel 14. The movement directions of the control plate 12 and the driven plate 13 are opposite. The opening of the guide groove 10 can provide space for the movement of the connecting frame 5 and the extension frame 9.

[0056] When the width is greater than that of the connecting frame 5 and the extending frame 9, the normal sliding process of the connecting frame 5 and the extending frame 9 can be ensured, and the driven plate 13 and the control plate 12 are respectively engaged with the gear blocks on both sides of the outer wall of the driving wheel 14 to ensure that the driven plate 13 slides upward when the control plate 12 slides downward, and when the driven plate 13 slides downward, the control plate 12 can slide upward.

[0057] There are two driven plates 13 and two control plates 12, which are respectively installed inside the two gate piers 1. The gate groove is a cross-shaped structure. The side walls of the connecting head 16 and the top head 6 are respectively installed with extension blocks 17 that fit with the inner wall of the gate groove. One side of the extension block 17 is a triangular structure. The side wall of the bracket 3 is provided with a movable groove 11 for the connecting frame 5 to slide. The two driven plates 13 and the control plate 12 can enable the extension frame 9 to drive the two sides of the cleaning plate 8 respectively, so that the upward sliding process of the cleaning plate 8 is more stable, so that the rust removal effect on the surface of the gate 2 is better.

[0058] The setting of the extension block 17 can make the ejecting head 6 and the connecting head 16 better correspond to the cross-shaped gate groove. The sliding process of the extension block 17 in the gate groove can prevent the connecting head 16 and the ejecting head 6 from separating from the inside of the gate groove during the sliding process, and the triangular structure of the extension block 17 can also eject the residue in the gate groove to ensure the normal sliding process of the connecting head 16 and the ejecting head 6 in the gate groove.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
