Abstract
Description
Technical Field
[0001] This invention relates to the field of hydraulic culvert technology, and in particular to an adjustable full-stroke culvert screw sleeve structure. Background Technology
[0002] A culvert is a hydraulic device used to control water flow, typically for irrigation, drainage, and flood control. It is a waterway with gates to regulate water level and flow to meet various water conservancy needs. A hydraulic culvert generally consists of gates, screw rods, and other components. Different types of gates can be selected according to different requirements, such as high-speed gates, flat gates, and curved gates. The hoist is the device used to open and close the gate.
[0003] After the water flow is controlled by driving the gate with a screw, the opening between the screw and the lifting device is easily exposed. After a long period of use, rainwater can easily enter the interior of the lifting device through the opening between the screw and the lifting device. After long-term erosion by rainwater, it will seriously affect the service life of the lifting device and the screw, and at the same time, it will easily affect the normal use of the gate. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an adjustable full-stroke culvert screw sleeve structure, which facilitates the shielding of the opening between the lifting screw and the lifting equipment, reducing erosion from rainwater and other sources, and effectively improving the service life of the lifting screw and the lifting equipment.
[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:
[0006] An adjustable full-stroke culvert screw sleeve structure includes a roof, a lifting screw, and a lifting device. A first sleeve is rotatably connected to the end of the lifting screw. The first sleeve has symmetrically symmetrically formed fixing grooves on its exterior. A disassembly assembly is provided on the exterior of the first sleeve, including a fixing block mounted on the first sleeve. Support rods are symmetrically mounted on the exterior of the lifting device, and these support rods are movably connected to the first sleeve. A second sleeve is movably connected to the exterior of the first sleeve, and a second fixing plate is mounted on its exterior. An infrared sensor and a telescopic motor are mounted on the exterior of the first sleeve, and the infrared sensor is connected to the telescopic motor via a wire. By providing the first sleeve, when the lifting screw moves downwards, the first sleeve can fit against the lifting device through the second sleeve, thus effectively shielding the opening between the lifting screw and the lifting device, reducing erosion from rainwater, and improving the service life of the lifting screw and the lifting device.
[0007] The above technical solution further includes:
[0008] The first protective sleeve has a third circular groove symmetrically formed on its outer side. A movable rod is movably connected to the outer side of the third circular groove. A first fixing plate is symmetrically installed on the outer side of the second protective sleeve, and a second spring is installed on the outer side of the first fixing plate. The end of the second spring away from the first fixing plate is installed on the outer side of the first protective sleeve. By setting the second protective sleeve, it is easier to make the first protective sleeve fit more tightly with the lifting equipment, and to avoid gaps between the second protective sleeve and the lifting equipment due to debris or other reasons, which could easily lead to rainwater intrusion.
[0009] The first protective sleeve has a second circular groove symmetrically formed on its outer side, and the second circular groove is movably connected to the support rod. The size of the opening of the second circular groove is adapted to the size of the support rod.
[0010] The lifting device is externally mounted with a first annular plate, the size of the opening of the first protective cylinder being adapted to the size of the first annular plate. The lifting device is externally mounted with a second annular plate, the outer side of the second protective cylinder having an annular groove, the size of the opening of the annular groove being adapted to the size of the second annular plate.
[0011] The disassembly assembly includes a fixed box symmetrically mounted on the outside of the first protective cylinder. A first spring is mounted on the side wall of the fixed box. The end of the first spring away from the side wall of the fixed box is fixedly connected to a fixed block. A push rod is mounted on the side of the fixed block near the first spring. The push rod is movably connected to the fixed box. A push handle is mounted on the end of the push rod away from the fixed block. By setting up the disassembly assembly, the first protective cylinder can be quickly disassembled from the lifting screw, thereby facilitating the cleaning of the first protective cylinder and increasing its service life.
[0012] The size of the fixing slot opening is adapted to the size of the fixing block.
[0013] The number of fixed slots is two sets and they are symmetrically distributed, and the number of fixed blocks is two sets and they are symmetrically distributed.
[0014] The upper part of the first protective sleeve is provided with a first circular groove, and the upper part of the first protective sleeve is movably connected to a connecting shaft. The connecting shaft is rotatably connected to the lifting screw. The upper part mentioned here refers to the upper part in the vertical direction.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0016] 1. In this invention, by setting a first protective sleeve, it is convenient to realize the full-stroke opening and closing of the gate when the lifting screw moves up and down, and the first protective sleeve is in close contact with the lifting equipment through the second protective sleeve, which is convenient to cover the opening of the lifting screw and the lifting equipment, reduce the corrosion of rainwater, and improve the service life of the lifting screw and the lifting equipment.
[0017] 2. In this invention, the second protective sleeve and the lifting device fit more tightly, avoiding gaps between the second protective sleeve and the lifting device due to debris or other reasons, which would allow rainwater to seep in.
[0018] 3. In this invention, by setting up a disassembly component, the first protective cylinder can be quickly removed from the lifting screw, which facilitates cleaning of the first protective cylinder and improves its service life. Attached Figure Description

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0029] Example 1: As Figure 1-8 As shown, an adjustable full-stroke culvert screw sleeve structure includes a roof 1, a lifting screw 2, and a lifting device 3. A first sleeve 4 is rotatably connected to the end of the lifting screw 2. The first sleeve 4 has symmetrically opened fixing grooves 7 on its exterior. A disassembly assembly is provided on the exterior of the first sleeve 4, including a fixing block 11 set on the first sleeve 4. Support rods 12 are symmetrically installed on the exterior of the lifting device 3, and the support rods 12 are movably connected to the first sleeve 4. A second sleeve 15 is movably connected to the exterior of the first sleeve 4, and a second fixing plate 20 is installed on the exterior of the first sleeve 15. An infrared sensor 21 is installed on the exterior of the first sleeve 4, and a telescopic motor 22 is installed on the exterior of the first sleeve 4. The infrared sensor 21 and the telescopic motor 22 are connected by a wire.
[0030] Furthermore, the first protective sleeve 4 has a third circular groove 19 symmetrically opened on its exterior, and a movable rod 17 is movably connected to the exterior of the third circular groove 19; the second protective sleeve 15 has a first fixing plate 16 symmetrically installed on its exterior, and a second spring 18 is installed on the exterior of the first fixing plate 16, with one end of the second spring 18 away from the first fixing plate 16 installed on the exterior of the first protective sleeve 4.
[0031] Furthermore, the outer side of the first protective sleeve 4 is symmetrically provided with a second circular groove 13, and the second circular groove 13 is movably connected to the support rod 12. The size of the opening of the second circular groove 13 is adapted to the size of the support rod 12.
[0032] Furthermore, a first annular plate 24 is installed on the outside of the lifting device 3, and the size of the opening of the first protective cylinder 4 is adapted to the size of the first annular plate 24. A second annular plate 25 is installed on the outside of the lifting device 3, and an annular groove 23 is opened on the outside of the second protective cylinder 15. The size of the opening of the annular groove 23 is adapted to the size of the second annular plate 25. A first circular groove 5 is opened on the outside of the first protective cylinder 4. A connecting shaft 6 is movably connected to the outside of the first protective cylinder 4, and the connecting shaft 6 is rotatably connected to the lifting screw 2.
[0033] The working principle of the adjustable full-stroke culvert screw sleeve structure based on Embodiment 1 is as follows: When the lifting screw 2 is driven to descend by the lifting device 3, the lifting screw 2 can rotate during the descent. Since the lifting screw 2 rotates between itself and the first sleeve 4 via the connecting shaft 6, and is movably connected to the second circular groove 13 via the support rod 12, the first sleeve 4 can move vertically along the support rod 12. Therefore, when the lifting screw 2 descends, it can drive the first sleeve 4 to move closer to the lifting device 3. Until the first annular plate 24 is inserted into the opening of the first protective cylinder 4; while the first protective cylinder 4 is moving, it drives the second protective cylinder 15 to move closer to the lifting device 3, until the annular groove 23 on the outside of the second protective cylinder 15 is in contact with the second annular plate 25, and at the same time, the second protective cylinder 15 is in contact with the lifting device 3. After the second protective cylinder 15 is in contact with the lifting device 3, the first protective cylinder 4 will continue to move, while driving the movable rod 17 to move into the third circular groove 19. At this time, the second spring 18 contracts, thereby restoring the return force generated by the contraction of the second spring 18. The force drives the second protective cylinder 15 to fit tightly against the lifting device 3, reducing gaps. Simultaneously, the infrared sensor 21 detects the distance between the second protective cylinder 15 and the lifting device 3. When the second protective cylinder 15 and the lifting device 3 cannot fit tightly due to debris or other reasons, the telescopic motor 22 is activated. The output shaft of the telescopic motor 22 drives the second fixed plate 20 to move closer to the lifting device 3, simultaneously moving the second protective cylinder 15 to facilitate its fit. The first protective sleeve 4 is kept in close contact with the lifting device 3 at all times. By making the first protective sleeve 4 close to the lifting device 3, the opening of the lifting screw 2 and the lifting device 3 is blocked, reducing the corrosion of rainwater and other factors, improving the service life of the lifting screw 2 and the lifting device 3, and facilitating intelligent adjustment of the second protective sleeve 15 at any time. The first protective sleeve 4 is more tightly attached to the lifting device 3 through the second protective sleeve 15, which prevents the second protective sleeve 15 from having gaps between it and the lifting device 3 due to the presence of foreign objects, thus preventing rainwater from seeping in.
[0034] Example 2: Figure 1-8As shown, based on Embodiment 1, the disassembly assembly includes a fixed box 8 symmetrically installed on the outside of the first protective sleeve 4, a first spring 10 installed on the side wall of the fixed box 8, a fixed connection between the end of the first spring 10 away from the side wall of the fixed box 8 and the fixed block 11, a push rod 9 installed on the side of the fixed block 11 near the first spring 10, the push rod 9 being movably connected to the fixed box 8, a push handle 14 installed on the end of the push rod 9 away from the fixed block 11, the size of the opening of the fixed groove 7 being adapted to the size of the fixed block 11, the number of fixed grooves 7 being two sets and symmetrically distributed, and the number of fixed blocks 11 being two sets and symmetrically distributed.
[0035] In this embodiment, the design allows for maintenance of the first protective sleeve 4 after prolonged use. The push handle 14 can be pulled away from the other side, moving the push rod 9 and simultaneously retracting the first spring 10. As the push rod 9 moves, it moves the fixing block 11 to the outside of the fixing groove 7. This eliminates the need to insert the fixing block 11 into the fixing groove 7 to fix the connecting shaft 6; the push handle 14 can be pulled directly to move the connecting shaft 6 to the outside of the first circular groove 5, allowing for quick disassembly and maintenance of the first protective sleeve 4. Once maintenance of the first protective sleeve 4 is complete, the handle can be pulled away from the other side. Pull the push handle 14 in the direction of the square to retract the fixing block 11 into the fixed box 8, and at the same time retract the first spring 10, insert the connecting shaft 6 into the first circular groove 5 until the fixing groove 7 corresponds to the position of the fixing block 11. Then release the push handle 14 to reset the first spring 10 in the retracted state, and at the same time drive the fixing block 11 to reset, so that the fixing block 11 is reinserted into the fixing groove 7, and the first protective sleeve 4 is reinstalled. This makes it easy to quickly remove the first protective sleeve 4 from the lifting screw 2, thereby facilitating the cleaning of the first protective sleeve 4 and improving the service life of the first protective sleeve 4.

Any substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
