Description

Technical Field

[0001] The utility model relates to the technical field of water outlet protection for water conservancy irrigation, in particular to a water outlet protection base device for water conservancy irrigation. Background Art

[0002] The water outlet protection base device for water conservancy irrigation is an infrastructure used to protect the water outlet of the irrigation system. This device usually consists of the following parts: Base and support structure: used to firmly support and protect the water outlet equipment, which can be a concrete base, reinforced concrete base or support frame and other structures. Filter: A filter installed near the water outlet equipment to prevent solid particles such as impurities, silt, and aquatic plants from entering the irrigation system, and to protect the water-passing equipment and irrigation channels from being blocked. Anti-leakage and anti-scour design: The base device needs to have an anti-leakage and anti-scour design to prevent irrigation water from impacting and damaging the soil around the base, and to prevent base infiltration and soil erosion.

[0003] However, the water outlet protection base device used in the past for water conservancy irrigation has no buffer device when the water outlet pipe encounters a collision, which results in the failure to protect the water outlet pipe well. In addition, in some mountainous areas, some devices do not have an anti-backflow mechanism, which results in the failure to prevent backflow in areas prone to backflow. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a water outlet protection base device for water conservancy irrigation, which is an improvement over the previous water outlet protection base device for water conservancy irrigation, which has no buffer device, resulting in the inability to protect the water outlet pipe well, and has no anti-backflow mechanism, resulting in the device being unable to prevent backflow well in areas prone to backflow.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water outlet protection base device for water conservancy irrigation, comprising a chassis, wherein the four corners of the chassis are threadedly connected with fixed screw cones, an inner shell is fixedly connected to the middle of the upper end of the chassis, a plurality of anti-collision mechanisms are fixedly connected to the outer side of the inner shell, an upper cover is threadedly connected to the middle of the inner shell by screws, an upper circular plate is fixedly connected to the upper side of the middle of the inner shell, an outer shell is fixedly connected to the lower end of the upper circular plate, and an anti-backflow mechanism is arranged above the middle of the upper side of the chassis.

[0006] Through the above technical solution, the chassis can provide a good fixation for the device, and the fixing screw cone can be inserted into the soil so that the entire device is firmly fixed on the ground. The inner shell provides a fixed position for the anti-collision mechanism, and the anti-collision mechanism also protects the water outlet well to reduce the impact of the collision. The anti-collision mechanism can well reduce the impact of the collision and make the water outlet safer. The screws can connect the upper cover and the inner shell, and the upper cover can protect the water outlet from sewage corrosion and collision. The upper circular plate can seal the anti-collision mechanism to prevent rainwater from accumulating between the inner shell and the outer shell, and prevent rainwater from corroding the anti-collision mechanism. The anti-backflow mechanism can prevent backflow from occurring in some mountainous areas and areas prone to backflow. Reduce the damage of backflow to crops.

[0007] Furthermore, the anti-collision mechanism includes a slide rail, one side of the slide rail is slidably connected to multiple sliders, one end of the multiple sliders is fixedly connected to multiple springs, one side of the multiple sliders is fixedly connected to multiple elastic elliptical arcs, and the lower end of the anti-collision mechanism is fixedly connected to the chassis.

[0008] Through the above technical solution, when the device is hit, the elastic elliptical arc will be deformed, the slider can slide on the slide rail, and the slider will transfer part of the force to another elastic elliptical arc. Spring 2 can make the force required for the elastic elliptical arc to deform greater, thereby better sharing part of the anti-collision mechanism.

[0009] Furthermore, the anti-backflow mechanism includes a nut, one end of the nut is threadedly connected to a threaded tube, the inner wall of the threaded tube is slidably connected to a lower tube, the middle lower side of the inner wall of the threaded tube is fixedly connected to an anti-backflow block 1, and the middle lower side of the lower tube is fixedly connected to an anti-backflow block 2.

[0010] Through the above technical solution, the nut can seal the threaded pipe when water is not used, the lower pipe and the threaded pipe fit tightly, and the lower pipe provides a fixed position for the anti-backflow block 2. As a result, the anti-backflow block 2 can block the water outlet that is not completely blocked by the anti-backflow block 1, and the anti-backflow block 2 and the anti-backflow block 1 can seal the threaded pipe to avoid the phenomenon of backflow.

[0011] Furthermore, the upper and lower sides of the middle portion of the anti-backflow block 1 can be slidably connected to one side of the lower portion of the inner wall of the lower tube.

[0012] Through the above technical solution, the anti-backflow block 1 slides with the inner wall of the lower pipe to ensure that when water is used again, the anti-backflow block 1 and the anti-backflow block 2 are aligned to open the water outlet. When water is not used, they are staggered to close the water outlet.

[0013] Furthermore, one side of the backflow prevention block 2 is slidably connected to one side of the backflow prevention block.

[0014] Through the above technical solution, the water outlet can be better sealed and sealed more tightly.

[0015] Furthermore, a plurality of springs 1 are fixedly connected at the middle groove of the chassis, and a latch is fixedly connected to one end of the spring 1.

[0016] Through the above technical solution, the spring 1 can provide a buffer for the water outlet. When the device is hit, it can ensure that the water outlet will not be damaged by being squeezed by the chassis. The buckle is used to better fix the water outlet.

[0017] Furthermore, the inner wall of the upper cover is tightly attached to the outer upper end of the inner shell.

[0018] Through the above technical solution, the sealing performance of the device can be better guaranteed, and water will not accumulate inside the device when it rains.

[0019] The utility model has the following beneficial effects:

[0020] 1. In the utility model, the elastic elliptical arc, the spring, the spring 1, the fixing screw cone and the clamping bolt in the anti-collision mechanism can reduce the impact received by the water outlet when it is hit, thereby protecting the water outlet from damage and making the water outlet safer.

[0021] 2. In the utility model, the lower tube can be sealed by sliding and fitting between the anti-backflow block 2 and the anti-backflow block 1 in the anti-backflow mechanism and the lower tube, thereby preventing the phenomenon of backflow, and the internal space of the lower tube can be adjusted to adjust the speed of the water flow.

[0034] The chassis 2 can provide a good fixation for the device, and the fixing screw cone 1 can be inserted into the soil so that the entire device is firmly fixed on the ground. The inner shell 11 provides a fixed position for the anti-collision mechanism 5, and the anti-collision mechanism 5 also protects the water outlet well to reduce the impact of the collision. The anti-collision mechanism 5 can well reduce the impact of the collision and make the water outlet safer. The screw 10 can connect the upper cover 8 and the inner shell 11, and the upper cover 8 can protect the water outlet from sewage corrosion and collision. The upper circular plate 6 can seal the anti-collision mechanism 5 to prevent rainwater from accumulating between the inner shell 11 and the outer shell 7, and prevent rainwater from corroding the anti-collision mechanism 5. The anti-backflow mechanism 9 can prevent backflow from occurring in some mountainous areas and areas prone to backflow. To reduce the damage to crops caused by backflow, the lower end of the outer shell 7 is fixed to the chassis 2 to increase the firmness of the device.

[0035] Reference Figure 5-Figure 8 The anti-collision mechanism 5 includes a slide rail 502, one side of which is slidably connected with a plurality of sliders 503, one end of which is fixedly connected with a plurality of springs 2 504, one side of which is fixedly connected with a plurality of elastic elliptical arcs 501, and the lower end of the anti-collision mechanism 5 is fixedly connected to the chassis 2. The anti-backflow mechanism 9 includes a nut 901, one end of which is threadedly connected with a threaded tube 902, the inner wall of which is slidably connected with a lower tube 904, the middle lower side of the inner wall of which is fixedly connected with an anti-backflow block 1 903, and the middle lower side of which is fixedly connected with an anti-backflow block 2 905.

A plurality of springs 3 are fixedly connected to the groove in the middle of the chassis 2, and one end of the spring 3 is fixedly connected to the latch 4. The inner wall of the upper cover 8 is closely attached to the outer upper end of the inner shell 11.

[0036] When the device is hit, the elastic elliptical arc 501 will be deformed, and the slider 503 can slide on the slide rail 502.
