Description

Technical Field

[0001] This application relates to the technical field of culverts, and particularly to a passing culvert for farmland water conservancy projects. Background Art

[0002] Under the existing farmland planning, channels are usually provided on the periphery of the farmland to facilitate guiding water into the channels for irrigating the farmland. According to the different areas of the farmland, the widths of the channels will also change accordingly to meet the irrigation requirements and increase the farmland yield.

[0003] A culvert is a pipeline buried underground, generally cast with reinforced concrete, and small culverts are also made of metal materials. Culverts are generally used as water conveyance pipelines.

[0004] In a utility model patent with the patent publication number CN212865857U, for example, a box culvert structure for a farmland water conservancy project is proposed. A cushion layer is laid on the bottom surface of the channel, which facilitates connecting and laying box culvert monomers in sequence to form a box culvert pipeline. The box culvert pipeline communicates with the opposite sides of the cushion layer, and then a main body layer is filled on the upper side of the cushion layer and the box culvert pipeline. The main body layer wraps and protects the box culvert pipeline. Finally, a panel layer is laid on the main body layer to facilitate personnel to cross the channel. When irrigating, water passes through the main body layer and the cushion layer from the box culvert pipeline, and it is not easy to affect the flow of water.

[0005] However, this box culvert structure for a farmland water conservancy project has the following defects: the water body flowing through the device is generally taken from an open water area, and there may be some large garbage and impurities in the input water body, resulting in the box culvert pipeline being prone to blockage after long-term use, and it is not convenient for maintenance personnel to clean the blocked impurities and garbage therein. Utility Model Content

[0006] In order to improve the problem that the box culvert pipeline is prone to blockage after long-term use and it is not convenient for maintenance personnel to clean the blocked impurities and garbage therein, this application provides a passing culvert for a farmland water conservancy project.

[0007] The passing culvert for a farmland water conservancy project provided by this application adopts the following technical solutions:

[0008] A culvert pipe for farmland water conservancy projects, including a diversion part, an inlet part and a retention part. One end of the inlet part close to the diversion part is communicated with the diversion part, and the retention part is detachably connected to the top of the inlet part. The inlet part includes an input section, a flow turning section and an output end. There is a height difference between the input section and the output end, and they are communicated by the flow turning section. The upper end of the flow turning section extends above the input section. An input port and an output port are respectively formed on the opposite sides of the input section and the output end, and a cleaning port is formed at the upper end of the flow turning section. The retention part includes a top plug, a retention bottle and a rubber sleeve. The bottom of the top plug is detachably connected and fixed to the top of the retention bottle. The rubber sleeve is sleeved on the upper part of the outer wall of the retention bottle. The retention bottle extends into the flow turning section from the cleaning port, and impurities flowing through the retention bottle are retained in the retention bottle by changing the size of the holes on its surface.

[0009] Furthermore, the culvert pipe for farmland water conservancy projects further includes two fixing seats, which are symmetrically arranged on the opposite sides outside the inlet part. Concave areas matching the inlet part are formed on the opposite sides of the two fixing seats. The four corners of the two fixing seats are connected and fixed by locking parts, and a threaded hole matching the top plug is jointly formed at the top of the two fixing seats.

[0010] Furthermore, a threaded area for connecting and matching with the threaded hole on the fixing seat is formed on the outer wall of the top plug. A connecting plug for connecting and matching with the retention bottle is formed at the bottom of the top plug. An alignment area aligned with the top plane of the fixing seat is formed at the top of the threaded area, and a convex handle protruding upward is formed at the top of the alignment area.

[0011] Furthermore, a plurality of drip holes evenly opened on the retention bottle are formed at the bottom of the outer wall of the retention bottle. The drip holes communicate with the inner cavity of the retention bottle. A second opening communicating with the inner cavity of the retention bottle is formed at the upper part of the outer wall of the retention bottle. The second opening faces the inner cavity of the input section. The outer diameter of the rubber sleeve is adapted to the inner diameter of the flow turning section. A notch identical to the second opening is formed in the area of the rubber sleeve facing the second opening. The drip holes formed on the retention bottle are all located below the rubber sleeve, and the diameter of the drip holes is smaller than the width or height of the second opening. The outer diameter of the retention bottle is smaller than the inner diameter of the flow turning section.

[0012] Furthermore, the culvert pipe for farmland water conservancy projects further includes a support part, which is arranged below the diversion part, and the top of the support part supports the bottom wall of the diversion part.

[0013] The beneficial technical effect of the present application is that through the coordinated arrangement of the inlet part, the interception part and the diversion part, when the water body used for agricultural water conservancy irrigation is used for diversion by the passing culvert, larger impurities in the water body input into the passing culvert can be intercepted, and the intercepted impurities can be regularly removed and cleaned, thereby reducing the blockage of the passing culvert during use and facilitating maintenance and management by maintenance personnel.

DETAILED DESCRIPTION

[0020] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0021] The present application embodiment discloses a culvert for use in farmland water conservancy projects. Figure 1, the culvert pipe for farmland water conservancy projects may include an inlet section 10, two fixed seats 20, an interception section 30, a diversion section 40, and a support section 50. The two fixed seats 20 are symmetrically arranged on the opposite sides outside the inlet section 10, and concave areas that cooperate with the inlet section 10 are formed on the facing sides of the two fixed seats 20. After connecting and fixing the four corners of the two fixed seats 20 with locking parts such as bolts or rivets, the main part of the inlet section 10 can be wrapped and fixed between the two fixed seats 20. The interception section 30 is inserted into the inlet section 10 from the top of the two fixed seats 20, and the interception section 30 and the inlet section 10 are detachably assembled for use. The interception section 30 can intercept impurities and garbage in the water flowing through the inlet section 10 and the interception section 30 and temporarily store them in the interception section 30. One end of the inlet section 10 close to the diversion section 40 is communicated with the diversion section 40, and the diversion section 40 is used to direct the water output from the inlet section 10 to the farmland. The support section 50 is arranged below the diversion section 40, and the top of the support section 50 is used to support the bottom wall of the diversion section 40.

[0022] Refer to Figure 2 and Figure 3 , the inlet section 10 includes an input section 11, a flow turning section 12, and an output end 13. There is a height difference between the input section 11 and the output end 13, and the input section 11 is arranged above the output end 13. The input section 11 and the output end 13 are connected by the flow turning section 12, and the upper end of the flow turning section 12 extends above the input section 11. Input ports and output ports are respectively formed on the opposite sides of the input section 11 and the output end 13; a cleaning port is formed at the upper end of the flow turning section 12.

[0023] The interception section 30 includes a top plug 31, a retention bottle 32, and a rubber sleeve 33. The bottom of the top plug 31 is detachably connected and fixed to the top of the retention bottle 32. The tops of the two fixed seats 20 jointly form a threaded hole that cooperates with the top plug 31, so that the interception section 30 is integrally fixed after the top plug 31 is screwed tightly with the threaded hole. The retention bottle 32 extends into the flow turning section 12 from the cleaning port, and the retention bottle 32 can intercept impurities flowing through the retention bottle 32 in the retention bottle 32 by changing the size of the holes on its surface and allow the water to flow out. The rubber sleeve 33 is sleeved on the upper part of the outer wall of the retention bottle 32, and the rubber sleeve 33 is used to assist in preventing water from overflowing from the threaded hole jointly formed by the tops of the two fixed seats 20.

[0024] Refer to Figure 4A threaded area 311 is formed on the outer wall of the top plug 31 to be connected and matched with the threaded hole on the fixing seat 20. A connecting plug 312 is formed at the bottom of the top plug 31 to be connected and matched with the retention bottle 32, so that the retention bottle 32 can be clamped and fixed below the top plug 31. An alignment area 313 is formed on the top of the threaded area 311 to be aligned with the top plane of the fixing seat 20, so that when the road culvert used for farmland water conservancy projects is buried under the road surface, the top of the fixing seat 20 and the alignment area 313 can be flush with the road surface. A convex handle 314 protruding upward is formed on the top of the alignment area 313. When cleaning and maintaining, the maintenance personnel can hold the convex handle 314 to loosen the top plug 31, so that the interception part 30 can be taken out upward, and the retention bottle 32 can be disassembled for cleaning.

[0025] See also Figure 5 The bottom of the outer wall of the retention bottle 32 is formed with a plurality of drip holes 321 evenly arranged on the retention bottle 32; the upper part of the outer wall of the retention bottle 32 is formed with a second opening 323 communicating with the inner cavity of the retention bottle 32; the top of the retention bottle 32 is formed with a first opening 322 engaged with the connecting plug 312. The drip holes 321, the first opening 322 and the second opening 323 are all in communication with the inner cavity of the retention bottle 32. The diameter of the drip hole 321 is smaller than the width or height of the second opening 323. When the water in the input section 11 flows into the diversion section 12, it can enter the retention bottle 32 from the second opening 323 and be discharged from the drip hole 321, and the garbage and impurities are trapped at the bottom of the retention bottle 32. The outer diameter of the rubber sleeve 33 covering the retention bottle 32 is adapted to the inner diameter of the diverting section 12, and a notch identical to the second opening 323 is formed in the area of ​​the rubber sleeve 33 facing the second opening 323 to prevent the rubber sleeve 33 from preventing water from flowing into the retention bottle 32. The drip holes 321 formed on the retention bottle 32 are all located below the rubber sleeve 33 to prevent the rubber sleeve 33 from preventing water from flowing out of the retention bottle 32.

[0026] In this embodiment, the outer diameter of the retention bottle 32 is smaller than the inner diameter of the diverting section 12 , so that the water flowing out of the drip hole 321 can flow into the output end 13 and be discharged.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
