Description

Technical Field

[0001] This utility model relates to the technical field of siphon reservoir water conveyance devices, and in particular to a siphon reservoir water conveyance device. Background Technology

[0002] In reservoir siphon water conveyance operations, the device must simultaneously meet the core requirements of stable and fixed siphon pipes and unobstructed water conveyance channels. It must ensure that the pipes do not loosen or shift under the impact of water flow, wind, and other external forces to guarantee water conveyance efficiency, while also preventing weeds, floating objects, and other impurities in the reservoir from clogging the pipes to maintain continuous water conveyance.

[0003] However, existing siphon-type reservoir water conveyance devices have significant shortcomings: the existing devices only fix the siphon pipe with simple brackets, which is not strong enough. The pipe is easily loosened or even shifted by water flow vibration or wind, which not only reduces the water conveyance efficiency, but may also cause water leakage due to the failure of the seal at the pipe connection. In addition, weeds, stones, floating objects and other impurities in the reservoir can easily enter the siphon pipe with the water flow, causing the pipe to be blocked. After the blockage, the entire water conveyance device must be stopped and disassembled to clean it, which not only increases the maintenance workload and time cost, but also interrupts the water conveyance operation and affects the stability of the water supply.

[0004] Therefore, those skilled in the art have provided a siphon-type reservoir water conveyance device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a siphon-type reservoir water conveyance device. Through a fixed mechanism, a U-shaped fixing frame and a limiting clip form a wrap-around fixation. A return spring drives a threaded rod to engage in a locking hole for initial fixation, and an annular threaded plate screws into an annular threaded groove for secondary locking. This double fixation ensures that the siphon pipe does not loosen or shift under water flow vibration or wind. Simultaneously, an anti-clogging mechanism is used, with a protective net inside the fixing ring intercepting weeds and other impurities at the source to prevent pipe blockage. A threaded main collar and a reverse-threaded external collar provide double reinforcement to prevent the fixing ring from falling off. The fixing ring can be quickly disassembled for cleaning or replacement of the protective net. The combination of these two mechanisms ensures smooth and stable water conveyance and reliable device operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A siphon-type reservoir water conveyance device includes a dam body and a siphon pipe. The siphon pipe is installed on the upper end face of the dam body through multiple fixing mechanisms, and anti-clogging mechanisms are provided on both sides of the siphon pipe. The fixing mechanism includes a U-shaped fixing frame and a limiting strip. The U-shaped fixing frame is fixedly connected to the upper end face of the dam body. The front and rear ends of the limiting strip are provided with adjustment grooves. The rear inner wall of the adjustment groove is fixedly connected with a return spring. The front end of the return spring is fixedly connected with a movable seat. The front end face of the movable seat is fixedly connected with a threaded rod. The front and rear ends of the U-shaped fixing frame are provided with engagement holes near the top. The threaded rod is engaged in the engagement holes. The above technical solution provides bottom support and lateral limiting for the siphon pipe through the U-shaped fixing frame, forming a preliminary fixing foundation. The limiting clip, together with the reset spring in the adjustment groove, can drive the moving seat to automatically engage the threaded rod into the locking hole of the U-shaped fixing frame, realizing the rapid positioning and fixing of the siphon pipe. This solves the problems of cumbersome installation and poor adaptability of traditional fixing methods, and also facilitates quick disassembly during subsequent maintenance.

[0007] Furthermore, the anti-clogging mechanism includes a fixed ring, a first external threaded ring, and an external threaded collar. A protective net is fixedly sleeved inside the fixed ring, and a threaded main collar is fixedly connected to one side of the fixed ring. Both ends of the siphon tube are provided with annular grooves, and the threaded main collar is threadedly sleeved in the annular grooves. Through the above technical solution, the protective net inside the fixed ring can directly intercept impurities such as weeds and floating objects in the water flow, preventing the siphon pipe from becoming clogged at the source. The threaded main sleeve and the annular groove thread of the siphon pipe are matched to achieve a precise connection between the fixed ring and the siphon pipe, ensuring that the protective net does not shift under the impact of water flow and guaranteeing a stable filtration effect.

[0008] Furthermore, the first external threaded ring is fixedly connected to one side of the siphon pipe, and the second external threaded ring is fixedly sleeved on the outer wall of the fixed ring. The external threaded collar is threaded on the outer walls of the first and second external threaded rings, and the threads inside the external threaded collar are opposite to the threads inside the threaded main collar. The above technical solution involves simultaneously fitting external threaded collars onto the outer walls of both the first and second external threaded collars, thus forming a secondary fixation of the fixed ring. Furthermore, since the threads of the external threaded collars and the main threaded collars are opposite, the two will not loosen synchronously under the action of external forces such as water flow vibration. Instead, they will form a reverse locking effect, further improving the installation stability of the anti-clogging mechanism.

[0009] Furthermore, the siphon tube clamp is fitted inside the U-shaped fixing frame; The above technical solution involves inserting the siphon pipe into the U-shaped fixing frame. The U-shaped structure can wrap around and limit the siphon pipe from the bottom and sides, increasing the contact area while avoiding excessive local stress. This locking method is suitable for siphon pipes of different diameters, improving the versatility of the fixing mechanism, and ensuring the stability of the siphon pipe axis after installation, without affecting the water delivery efficiency.

[0010] Furthermore, a limiting sleeve is threadedly fitted on the outer wall of each of the two threaded rods, and an annular threaded plate is fixedly connected to the opposite side of each of the two limiting sleeves. An annular threaded groove is opened on the outer wall of the front and rear ends of the U-shaped fixing frame, and the annular threaded plate is threadedly fitted in the annular threaded groove. Through the above technical solution, by means of the threaded engagement between the limiting sleeve and the threaded rod, rotating the limiting sleeve can drive the annular threaded plate to screw into the annular threaded groove of the U-shaped fixing frame. On the basis of the threaded rod locking and fixing, a threaded locking structure is added to form a double fixing, which effectively prevents the device from becoming loose under the action of water flow vibration or wind force, and ensures the long-term stable operation of the siphon pipe.

[0011] Furthermore, the upper and lower end faces of the movable seat are fixedly connected to limit sliders, and the inner walls of the upper and lower ends of the adjustment groove are provided with limit grooves, and the limit sliders are slidably disposed in the limit grooves. With the above technical solution, when the threaded rod is extended or retracted by the movable seat, the upper and lower limit sliders slide synchronously along the limit groove on the inner wall of the adjustment groove, which restricts the movement trajectory of the movable seat, prevents it from deviating or getting stuck during the adjustment process, and ensures that the threaded rod can be accurately aligned with the engagement hole to complete the engagement, thereby improving the installation convenience and reliability of the fixing mechanism.

[0012] Furthermore, the two ends of the siphon tube are not located on the same horizontal plane; The above technical solution creates a natural height difference by having the two ends of the siphon pipe not on the same horizontal plane, providing the necessary potential energy conditions for the generation of the siphon phenomenon. No additional power is needed to drive the water flow; the water can be automatically transported by utilizing the height difference simply by creating negative pressure inside the pipe, thus reducing water transport energy consumption and improving the economic efficiency of the device operation.

[0013] Furthermore, multiple connecting rods are fixedly connected to the middle of the upper end face of the dam body. An installation plate is fixedly connected to the upper end of the connecting rods. A vacuum pump is fixedly connected to the lower end face of the installation plate. An air suction pipe is fixedly connected to the output end of the vacuum pump. The air suction pipe is fixedly connected to a siphon pipe. A one-way valve is installed on the air suction pipe. The above technical solution forms a stable support with the connecting rod and the mounting plate, providing a solid installation foundation for the vacuum pump. The vacuum pump draws air from the siphon pipe through the suction pipe, quickly creating negative pressure to start the siphon water delivery. The one-way valve on the suction pipe prevents air from flowing back into the siphon pipe, ensuring stable negative pressure inside the pipe and ensuring continuous and efficient siphon water delivery, avoiding water delivery interruption due to insufficient negative pressure.

[0014] This utility model has the following beneficial effects: 1. This utility model proposes a siphon-type reservoir water conveyance device. By adding a fixing mechanism, it solves the problem that traditional siphon pipes, which are only fixed by simple brackets, are prone to loosening and displacement due to water flow impact or wind force, leading to a decrease in water conveyance efficiency or even leakage. Specifically, the U-shaped fixing bracket and the limiting clip form a wrapping fixation, increasing the contact area with the siphon pipe and avoiding uneven local stress. In addition, the threaded rod driven by the return spring engages with the threaded locking of the annular threaded plate to achieve double fixation, preventing the fixing structure from loosening. It can remain stable even under long-term water flow vibration. Furthermore, the guide of the limiting slider and the slide groove ensures precise engagement. No special tools are required during installation, making operation convenient. At the same time, it is adaptable to the fixing requirements of siphon pipes of different diameters, improving the versatility of the device.

[0015] 2. This utility model proposes a siphon-type reservoir water conveyance device. By adding an anti-clogging mechanism, it solves the problem that traditional siphon-type water conveyance devices lack a dedicated anti-clogging structure, making them prone to blockage caused by weeds, floating objects, etc. entering the pipe in the reservoir. Moreover, the blockage is difficult to clean and affects the continuity of water conveyance. The protective net can accurately intercept impurities, preventing blockage from the source, ensuring the smooth flow of siphon water conveyance, and reducing the number of downtime maintenance caused by blockage. The double threaded connection ensures that the fixing ring will not fall off under the impact of water flow and allows for quick disassembly and assembly. When cleaning impurities, it is not necessary to disassemble the entire water conveyance device; only the fixing ring needs to be removed, shortening maintenance time. Furthermore, the modular design of the fixing ring and the protective net facilitates the individual replacement of the protective net after wear, reducing maintenance costs and adapting to the long-term water conveyance needs of reservoirs.

[0016] 3. The siphon-type reservoir water conveyance device proposed in this utility model has a fixed mechanism in which a U-shaped fixing frame and a limiting clip form a wrapping fixation. A return spring drives the threaded rod to engage with the locking hole to achieve initial fixation. The annular threaded plate is screwed into the annular threaded groove to complete the secondary locking. The double fixation ensures that the siphon pipe does not loosen or shift under water flow vibration or wind force. At the same time, the anti-clogging mechanism intercepts weeds and other impurities in the fixed ring from the source to prevent the pipe from being blocked. The threaded main collar and the reverse threaded external collar provide double reinforcement to prevent the fixed ring from falling off. The fixed ring can be quickly disassembled for cleaning or replacement of the protective net. The two work together to ensure smooth and stable water conveyance and reliable use of the device.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figure 1 , Figure 2 and Figure 3This utility model provides a specific embodiment: a siphon-type reservoir water conveyance device, including a dam body 1 and a siphon pipe 7. The siphon pipe 7 is installed on the upper end face of the dam body 1 by multiple fixing mechanisms 8. Anti-clogging mechanisms 9 are provided on both sides of the siphon pipe 7. The two ends of the siphon pipe 7 are not located on the same horizontal plane. The difference in height between the two ends of the siphon pipe 7 creates a natural height difference, providing the necessary potential energy conditions for the generation of the siphon phenomenon. No additional power is needed to drive the water flow. The water flow can be automatically conveyed by utilizing the height difference simply by forming a negative pressure inside the pipe, reducing water conveyance energy consumption and improving the economic efficiency of the device operation. A fixed connection is made at the middle of the upper end face of the dam body 1. Multiple connecting rods 2 are connected to an upper mounting plate 3, and a vacuum pump 4 is fixedly connected to the lower end of the mounting plate 3. An air suction pipe 5 is fixedly connected to the output end of the vacuum pump 4. The air suction pipe 5 is fixedly connected to the siphon pipe 7. A one-way valve 6 is installed on the air suction pipe 5. The connecting rods 2 and the mounting plate 3 form a stable support, providing a solid mounting base for the vacuum pump 4. The vacuum pump 4 draws air from the siphon pipe 7 through the air suction pipe 5, quickly forming a negative pressure to start the siphon water delivery. The one-way valve 6 on the air suction pipe 5 can prevent air from flowing back into the siphon pipe 7, ensuring stable negative pressure in the pipe, ensuring continuous and efficient siphon water delivery, and avoiding water delivery interruption due to insufficient negative pressure. The fixing mechanism 8 includes a U-shaped fixing frame 801 and a limiting strip 802. The U-shaped fixing frame 801 is fixedly connected to the upper end face of the dam body 1. The limiting strip 802 has adjustment grooves 803 on both its front and rear ends. A return spring 804 is fixedly connected to the inner wall of the rear end of the adjustment groove 803. A movable seat 805 is fixedly connected to the front end of the return spring 804. A threaded rod 806 is fixedly connected to the front end face of the movable seat 805. Engaging holes 807 are provided at the upper part of both the front and rear ends of the U-shaped fixing frame 801. The threaded rod 806 engages within the engaging holes 807. The U-shaped fixing frame 801 provides bottom support and lateral limiting for the siphon pipe 7, forming a preliminary fixing foundation. The limiting strip 802... 2. With the reset spring 804 in the adjusting groove 803, the moving seat 805 can drive the threaded rod 806 to automatically engage with the engaging hole 807 of the U-shaped fixing bracket 801, realizing the rapid positioning and fixing of the siphon tube 7. This solves the problems of cumbersome installation and poor adaptability of traditional fixing methods, and facilitates quick disassembly during subsequent maintenance. The siphon tube 7 is engaged and fitted inside the U-shaped fixing bracket 801. The U-shaped structure can form a wrap-around limiting effect on the siphon tube 7 from the bottom and sides, increasing the contact area while avoiding excessive local stress. This engaging method is compatible with siphon tubes 7 of different diameters, improving the versatility of the fixing mechanism 8, while ensuring the siphon tube 7 is properly positioned and fixed. After installation, the suction pipe 7 has a stable axis and does not affect the water delivery efficiency. Limiting sleeves 808 are threaded onto the outer walls of both threaded rods 806. Annular threaded plates 809 are fixedly connected to opposite sides of each limiting sleeve 808. Annular threaded grooves 810 are formed on the outer walls of both the front and rear ends of the U-shaped fixing frame 801. The annular threaded plates 809 are threaded into the annular threaded grooves 810. Through the threaded engagement of the limiting sleeves 808 and the threaded rods 806, rotating the limiting sleeves 808 can cause the annular threaded plates 809 to screw into the annular threaded grooves 810 of the U-shaped fixing frame 801. In addition to the locking and securing of the threaded rods 806, a threaded locking structure is added, forming a double fixation, effectively preventing the device from slipping in the water. To prevent loosening of the fixed mechanism under the action of flow vibration or wind, and to ensure the long-term stable operation of the siphon pipe 7, the upper and lower end faces of the movable seat 805 are fixedly connected with limit sliders 811, and the upper and lower inner walls of the adjustment groove 803 are provided with limit grooves 812. The limit sliders 811 are slidably set in the limit grooves 812. When the movable seat 805 drives the threaded rod 806 to extend or retract, the limit sliders 811 at the upper and lower ends slide synchronously along the limit grooves 812 on the inner wall of the adjustment groove 803, which restricts the movement trajectory of the movable seat 805 and prevents it from deviating or getting stuck during the adjustment process. This ensures that the threaded rod 806 can be accurately aligned with the locking hole 807 to complete the locking, and improves the installation convenience and reliability of the fixing mechanism 8. Reference Figure 1 , Figure 4 and Figure 5The anti-clogging mechanism 9 includes a fixed ring 902, a first external threaded ring 906, and an external threaded collar 901. A protective net 903 is fixedly fitted inside the fixed ring 902. A threaded main collar 904 is fixedly connected to one side of the fixed ring 902. Both ends of the siphon pipe 7 have annular grooves 905. The threaded main collar 904 is threaded into the annular grooves 905. The protective net 903 inside the fixed ring 902 can directly intercept weeds, floating objects, and other impurities in the water flow, preventing clogging of the siphon pipe 7 from the source. The threaded main collar 904 and the annular grooves 905 of the siphon pipe 7 are threadedly engaged to achieve a precise connection between the fixed ring 902 and the siphon pipe 7, ensuring that the protective net 903 does not shift under the impact of water flow and guaranteeing stable filtration effect. The first external threaded ring 906 is fixedly connected to one side of the siphon pipe 7. The second external threaded ring 907 is fixedly sleeved on the outer wall of the fixed ring 902. The external threaded collar 901 is threaded on the outer wall of the first external threaded ring 906 and the second external threaded ring 907. The thread in the external threaded collar 901 is opposite to the thread in the threaded main collar 904. By simultaneously sleeved on the outer wall of the first external threaded ring 906 and the second external threaded ring 907, a secondary fixation is formed for the fixed ring 902. Since the threads of the external threaded collar 901 and the threaded main collar 904 are opposite, under the action of external forces such as water flow vibration, the two will not loosen synchronously, but instead form a reverse locking effect, further improving the installation stability of the anti-clogging mechanism 9.

[0021] Working principle: This device achieves stable positioning of the siphon pipe 7 through the fixing mechanism 8, and ensures smooth water conveyance by relying on the anti-clogging mechanism 9. The dam body 1 provides the installation foundation for the whole. The design that the two ends of the siphon pipe 7 are not on the same horizontal plane provides the premise for siphon water conveyance. During installation and fixing, the siphon pipe 7 is first snapped into the U-shaped fixing frame 801 of the fixing mechanism 8. The threaded rods 806 on both sides of the limiting clip 802 are pushed to drive the moving seat 805 to compress the return spring 804 in the adjusting groove 803. The limiting slider 811 slides along the limiting slide groove 812 to ensure stability. After release, the return spring 804 pushes the threaded rod 806 into the snapping hole 807 of the U-shaped fixing frame 801 to complete the initial fixing. Then, the limiting sleeve 808 is rotated to drive the annular threaded plate 809 into the annular threaded groove 810 to achieve secondary locking. When installing the anti-clogging mechanism 9, the fixing ring 902 is... The threaded main collar 904 is screwed into the annular groove 905 of the siphon pipe 7. Then, the external threaded collar 901 is screwed into the outer wall of the first external threaded collar 906 and the second external threaded collar 907 to reinforce the external threaded collar 901. The threads of the external threaded collar 901 and the threaded main collar 904 are opposite. The protective net 903 inside the fixed ring 902 forms an impurity interception barrier. When water is pumped, the vacuum pump 4 below the mounting plate 3 is started. The mounting plate 3 is fixed to the dam body 1 through the connecting rod 2. The vacuum pump 4 draws air from the siphon pipe 7 through the suction pipe 5. The one-way valve 6 prevents air backflow. After negative pressure is formed in the pipe, the siphon principle is used to realize water pumping from the reservoir. During the water pumping process, the protective net 903 intercepts weeds and other impurities in the water to prevent the siphon pipe 7 from being blocked. If maintenance is required, the external threaded collar 901 and the threaded main collar 904 are unscrewed in the opposite direction to remove the fixed ring 902 and clean the protective net 903 to ensure continuous and smooth water pumping.
