Description

Technical Field

[0001] The utility model relates to the technical field of canal irrigation fittings, and more specifically, to a canal irrigation shunt conversion joint. Background Art

[0002] In dry weather, in order to ensure the normal growth of crops, it is usually necessary to artificially irrigate the crops to supplement the water required by the crops. Since the area of farmland is generally relatively wide, water needs to be shunted when irrigating at multiple positions. At this time, a shunt device (shunt conversion joint) is required.

[0003] The patent document with the publication number of CN220965893U discloses a farmland irrigation shunt device, which includes a main body. One side of the outer wall of the main body is communicated with a water inlet joint. A handle is fixedly connected to the top of the main body. A fixing plate is installed on the main body. A ground nail is fixedly connected to the bottom of the fixing plate. The other side of the outer wall of the main body is communicated with a shunt joint. A pressure regulating structure is installed on the inner wall of the shunt joint. The utility model relates to the technical field of farmland irrigation. Through the cooperation of a baffle, a shunt plate and a spring, after water enters through the water inlet interface, it flows through the jacks of the shunt plate in the shunt joint, and the plug blocks on the outer wall of the baffle are used for sealing. When the pressure in the cavity is relatively large, the baffle will be extruded by the spring, causing the plug blocks to move out of the jacks, enabling water to flow out in the shunt joint, solving the problem that in the prior art, when in use, water is directly discharged through the shunt joint, and when passing through a long water pipe, the water flow rate will be reduced, resulting in a reduction in the irrigation speed. However, for the shunt device in the prior art, the spring may become loose after long-term use. After the spring becomes loose, when encountering a relatively large water pressure, the water flow rate cannot be reduced. At the same time, if the water pressure is too small to compress the spring, the water flow cannot pass through the shunt joint, affecting the use. The shunt device in the prior art urgently needs to solve the problem of whether the tightness of the spring can be adjusted. Summary of the Utility Model

[0004] The utility model aims to provide a canal irrigation shunt conversion joint that can adjust the tightness of the spring and adapt to different water pressures to overcome the above deficiencies.

[0005] A canal irrigation shunt conversion joint includes a conversion box, a water inlet joint and a shunt joint communicated with the conversion box. A shunt plate is fixedly connected inside the water inlet joint. A plurality of jacks are opened on the shunt plate. A square column is fixedly connected to the side of the shunt plate away from the conversion box. A baffle slides on the square column. A plurality of flow equalizing holes are opened on the baffle. A plurality of plug blocks adapted to the jacks are fixedly connected to the side of the baffle close to the shunt plate. A spring is sleeved on the square column. One end of the spring is fixedly connected to the baffle. An adjusting mechanism for adjusting the tightness of the spring is further arranged inside the water inlet joint. The other end of the spring is connected to the adjusting mechanism.

[0006] Further, a plurality of the shunt joints are provided.

[0007] Further, the cross-section of the square column is rectangular.

[0008] Further, after the uniform flow holes and the jacks are infinitely extended along the length direction of the shunt joint, they do not coincide.

[0009] Further, the adjusting mechanism includes a threaded rod rotatably connected to the square column. A moving plate is penetrated and threadedly connected to the threaded rod. One end of the spring away from the baffle is fixedly connected to the moving plate.

[0010] Further, a plurality of limiting rods are fixedly connected to the side wall of the moving plate. Limiting grooves adapted to the limiting rods are formed in the inner wall of the shunt joint. One end of the limiting rod away from the moving plate slides in the limiting groove.

[0011] Further, a cross-shaped groove is formed at one end of the threaded rod away from the baffle.

[0012] Further, an installation groove is formed at the lower end of the conversion box, and a fixing mechanism is arranged in the installation groove.

[0013] Further, the fixing mechanism includes a cross plate arranged in the installation groove. A plurality of insertion rods are fixedly connected to the lower end surface of the cross plate. Sliding grooves are formed on both side walls of the installation groove. Both ends of the cross plate slide in the sliding grooves on the same side.

[0014] Further, the fixing mechanism further includes a positioning block fixedly connected to the side wall of the conversion box and a connecting frame arranged above the conversion box. Both ends of the connecting frame penetrate and slide in the positioning blocks on the same side. Pedals are fixedly connected to both sides of the cross plate. Both ends of the connecting frame are fixedly connected to the pedals on the same side.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In the present utility model, if the water pressure is relatively high, due to long-term use of the spring, the spring becomes loose and cannot reduce the water flow rate. Close the water source, unplug the water pipe connected to the shunt joint, and rotate the threaded rod to make the moving plate close to the shunt plate to tighten the spring to adapt to the relatively high water pressure. If the water pressure is too low to compress the spring, rotate the threaded rod to make the moving plate away from the shunt plate, then the spring can be loosened to adapt to the situation when the water pressure is low.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Specific embodiment:

[0027] Such as Figures 1-6As shown in the figure, a water channel irrigation diversion conversion joint includes a conversion box 1, a water inlet joint 2 connected to the conversion box 1, and a plurality of diversion joints 3. The water inlet joint 2 is used to connect an external water pipe to add water into the conversion box 1. The diversion joints 3 are connected to each sub-water pipe and are used to transport water to each water channel for diversion. A diversion plate 4 is fixedly connected inside the water inlet joint 2. A plurality of jacks 41 are opened on the diversion plate 4. A square column 5 is fixedly connected to the side of the diversion plate 4 away from the conversion box 1. The cross-section of the square column 5 is rectangular. A baffle 6 slides on the square column 5. A plurality of flow equalizing holes 61 for water passage are opened on the baffle 6. The flow equalizing holes 61 and the jacks 41 do not coincide after being infinitely extended along the length direction of the diversion joint 3. A plurality of insertion blocks 7 adapted to the jacks 41 are fixedly connected to the side of the baffle 6 close to the diversion plate 4. And during the process of the baffle 6 sliding close to the diversion plate 4, the insertion blocks 7 can just be inserted into the jacks 41 to seal the diversion plate 4. A spring 8 is sleeved on the square column 5. One end of the spring 8 is fixedly connected to the baffle 6. An adjusting mechanism 9 for adjusting the tightness of the spring 8 is further provided inside the water inlet joint 2. The other end of the spring 8 is connected to the adjusting mechanism 9. After the water inlet joint 2 is connected to a water source, water enters the conversion box 1. When the pressure in the conversion box 1 is relatively high, the baffle 6 is pushed away from the diversion plate 4 and the spring is compressed, so that the insertion blocks 7 are pulled out of the jacks 41, and the water is discharged from the diversion joint 3. When the diversion joint 3 is connected to a long water pipe, the reduction of the water flow rate can be avoided.

[0028] As Figures 1-6 shown, the adjusting mechanism 9 includes a threaded rod 91 rotatably connected to one end of the square column 5 away from the diversion plate 4 through a bearing seat (not shown in the figure). The threaded rod 91 penetrates and is threadedly connected with a moving plate 92. The end of the spring 8 away from the baffle 6 is fixedly connected to the moving plate 92. A plurality of limiting rods 93 are fixedly connected to the side wall of the moving plate 92. A limiting groove 31 adapted to the limiting rods 93 is opened on the inner wall of the diversion joint 3. The end of the limiting rod 93 away from the moving plate 92 slides in the limiting groove 31. The baffle 6 cooperates with the spring 8 to make the baffle 6 fit the diversion plate 4. At this time, the insertion blocks 7 are inserted into the jacks 41 to seal the side of the conversion box 1 where the diversion joint 3 is located. By rotating the threaded rod 91, the moving plate 92 can move on the threaded rod 91 under the cooperation of the limiting rods 93 and the limiting groove 31, so as to adjust the compression amount of the spring 8, and further adjust the tightness of the spring 8. If the water pressure is relatively high and the spring 8 becomes loose due to long-term use and cannot reduce the water flow rate, close the water source, unplug the water pipe connected to the diversion joint 3, and rotate the threaded rod 91 to make the moving plate 92 close to the diversion plate 4 to tighten the spring 8 to adapt to the relatively high water pressure. If the water pressure is relatively low and is not enough to compress the spring 8, by rotating the threaded rod 91 to make the moving plate 92 away from the diversion plate 4, the spring 8 can be loosened to adapt to the situation when the water pressure is relatively low.

[0029] As Figures 1-6As shown, one end of the threaded rod 91 away from the baffle 6 is provided with a slotted screwdriver slot 94. By cooperating a flat-blade screwdriver with the slotted screwdriver slot 94 and rotating the flat-blade screwdriver, the rotation of the threaded rod 91 can be realized.

[0030] As Figures 1-6 shown, an installation groove 10 is opened at the lower end of the conversion box 1, and a fixing mechanism 11 for preventing the conversion box 1 from undergoing lateral displacement is arranged in the installation groove 10.

[0031] As Figures 1-6 shown, the fixing mechanism 11 includes a cross plate 111 arranged in the installation groove 10. A plurality of insertion rods 112 are fixedly connected to the lower end surface of the cross plate 111 for inserting into the ground. Slide grooves 113 are opened on both side walls of the installation groove 10, and both ends of the cross plate 111 slide in the slide grooves 113 on the same side. By sliding the cross plate 111 to insert the insertion rods 112 into the ground, the lateral movement of the conversion box 1 can be avoided, improving stability.

[0032] As Figures 1-6 shown, the fixing mechanism 11 further includes positioning blocks 114 fixedly connected to both side walls of the conversion box 1 and a connecting frame 115 arranged above the conversion box 1. Both ends of the connecting frame 115 penetrate and slide through the positioning blocks 114 on the same side. Pedals 116 are fixedly connected to both sides of the cross plate 111, and both ends of the connecting frame 115 are fixedly connected to the pedals 116 on the same side. After connecting the flow splitting conversion joint, by stepping on the pedals 116, the cross plate 111 continues to move downward and the insertion rods 112 are inserted into the ground. After use, by pulling up the connecting frame 115, the insertion rods 112 are pulled out of the ground and the cross plate 111 moves upward. After the cross plate 111 contacts the upper wall of the installation groove 10, the whole flow splitting conversion joint can be lifted by pulling up the connecting frame 115, which is convenient for removing and carrying the flow splitting conversion joint, improving convenience.

[0033] The working principle of a kind of water channel irrigation flow splitting conversion joint in this embodiment is as follows: When in use, if the water pressure is large, due to the long-term use of the spring 8 resulting in spring relaxation, the water flow rate cannot be reduced. Close the water source, unplug the water pipe connected to the flow splitting joint 3, and rotate the threaded rod 91 to make the moving plate 92 approach the flow splitting plate 4 to tighten the spring 8 to adapt to the large water pressure; if the water pressure is small and insufficient to compress the spring 8, by rotating the threaded rod 91 to make the moving plate 92 away from the flow splitting plate 4, the spring 8 can be loosened to adapt to the situation of small water pressure, so that this joint can adapt to different water pressures; after use, by pulling up the connecting frame 115, the insertion rods 112 are pulled out of the ground and the cross plate 111 moves upward. By pulling up the connecting frame 115, the whole flow splitting conversion joint can be lifted, which is convenient for removing and carrying the flow splitting conversion joint, improving convenience.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
