Description

Technical Field

[0001] The utility model belongs to the field of drainage devices, and in particular relates to a rotary drainage pipe which is used in rice fields and can adjust the water level in real time. Background Art

[0002] The traditional rice field drainage system mainly uses L-shaped drainage pipes. Figure 3 , one end of the L-shaped drainage pipe is inserted in the ridge of the rice field, and the end with a higher height of the L-shaped drainage pipe is set as end a, and the other end is end b. End a of the L-shaped drainage pipe is connected to the rice field, and the other end b is connected to the canal outside the ridge. When the maximum water level in the rice field is higher than end a of the L-shaped drainage pipe, the water in the rice field will flow out of the rice field from end a of the L-shaped drainage pipe through end b of the drainage pipe, ensuring that the maximum water level in the rice field is always at the height of end a of the drainage pipe.

[0003] However, the maximum water level required for rice in different growth stages is also different. The traditional L-shaped drain pipe is set in the field ridge, so the height of the a end of the L-shaped drain pipe cannot be adjusted, resulting in the inability to adjust the maximum water level in the rice field, and thus cannot meet the needs of the rice growth period. Utility Model Content

[0004] The utility model discloses a rotary drainage pipe which is applied to a rice field and can adjust the water level in real time, and can adjust the maximum water level in the rice field.

[0005] The utility model discloses a rotary drainage pipe capable of adjusting the water level in real time and applied to a paddy field, comprising:

[0006] The water outlet pipe is inserted on the ridge of the rice field; one end of the water outlet pipe is located in the rice field and connected to the rice field, and the other end of the water outlet pipe is located outside the rice field and connected to the drainage channel outside the rice field;

[0007] The elbow joint has one end sleeved on the end of the outlet pipe connected to the rice field; the other end is higher than the horizontal plane M where the outlet pipe axis is located, as viewed from the axis of the outlet pipe; the elbow joint is connected to the outlet pipe;

[0008] The water inlet pipe has one end fixedly connected to the other end of the elbow joint, and the other end is higher than the horizontal plane M where the axis of the water outlet pipe is located when viewed from the axis of the water outlet pipe; the water inlet pipe is connected to the elbow joint; the water inlet pipe and the elbow joint can rotate around the axis of the water outlet pipe as a whole;

[0009] It also includes a movable component for facilitating the integral rotation of the water inlet pipe and the elbow joint; and a driving component for driving the water inlet pipe and the elbow joint to rotate as a whole.

[0010] In this solution, the elbow joint can rotate around the axis of the outlet pipe, so that the water inlet pipe and the elbow joint can rotate around the axis of the outlet pipe as a whole, thereby changing the height difference between the end of the water inlet pipe away from the elbow joint and the horizontal plane M, thereby achieving a change in the maximum water level in the rice field.

[0011] Furthermore, the activity component includes:

[0012] A plurality of bearings are sleeved on the water outlet pipe, and the inner ring of the bearing is fixedly connected to the water outlet pipe;

[0013] The sleeve is sleeved on multiple bearings at the same time, the axis of the sleeve coincides with the axis of the water outlet pipe, and the sleeve is fixedly connected to the elbow joint; the sleeve is fixedly connected to the outer rings of multiple bearings at the same time; the sleeve, the elbow joint and the water inlet pipe can be rotated around the axis of the water outlet pipe as a whole by relying on multiple bearings.

[0014] It is convenient for the casing, elbow joint and water inlet pipe to rotate. If there is no movable component, the outlet pipe, elbow joint and water inlet pipe need to be welded together, and then the whole is rotated around the axis of the outlet pipe. Since the outlet pipe is in the ridge, this method requires more manpower and may even fail to rotate.

[0015] Furthermore, the driving assembly comprises:

[0016] Support, installed on the ridge;

[0017] The non-rotating shaft end of the motor is mounted on the support; the rotating shaft of the motor is parallel to the axis of the water outlet pipe;

[0018] A driving gear is fixedly connected to the rotating shaft of the motor, and the axis of the driving gear coincides with the axis of the motor;

[0019] The driven gear is sleeved on the sleeve and fixedly connected to the sleeve. The axis of the driven gear coincides with the axis of the sleeve, and the driven gear meshes with the driving gear.

[0020] By means of remote communication, the operator remotely controls the motor and makes it rotate, so that the height difference between the end of the water inlet pipe away from the elbow joint and the horizontal plane M changes with the season, thereby changing the maximum water level in the rice field to meet seasonal requirements.

[0021] Furthermore, the number of the bearings is two, and the two bearings are respectively located at two ends of the sleeve.

[0022] The cost of two bearings is the lowest. Compared with using only one bearing, the two bearings are located at both ends of the sleeve and can stably support the rotation of the sleeve. Compared with using three bearings, the number of bearings is saved and the cost is saved.

[0023] Furthermore, the inner diameters of the water outlet pipe and the water inlet pipe are equal.

[0024] The reason why the outlet pipe and the inlet pipe are set to have equal inner diameters is to facilitate the unification of processing equipment. If the inner diameters of the inlet pipe and the outlet pipe are different, the cutting tool of the elbow joint needs to be adjusted when processing the elbow joint, which increases the processing difficulty. Beneficial Effects

[0025] This solution provides an elbow joint that can rotate around the axis of the water outlet pipe, so that the end of the water inlet pipe away from the elbow joint can change the distance to the horizontal plane M, thereby achieving the change of the maximum water level in the rice field.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See Figure 1 and Figure 2 , a rotary drainage pipe capable of adjusting water level in real time for use in a rice field, comprising:

[0032] The water outlet pipe 1, in this embodiment, is a straight circular pipe, which is horizontally inserted on the ridge of the rice field, and the water outlet pipe 1 cannot rotate around its own axis relative to the ridge; one end of the water outlet pipe 1 is connected to the rice field, and the other end is connected to the drainage ditch.

[0033] The elbow joint 2 is an L-shaped circular tube, and the two ends of the elbow joint 2 are respectively an X end and a Y end. The X end of the elbow joint 2 is sleeved on the end of the outlet pipe 1 located in the rice field, and the X end of the elbow joint 2 coincides with the axis of the outlet pipe 1. The elbow joint 2 is in the rice field, and the elbow joint 2 can rotate around the axis of the outlet pipe 1. From the axis of the outlet pipe 1, the Y end of the elbow joint 2 is located at the upper end of the horizontal plane M where the axis of the outlet pipe 1 is located.

[0034] Inlet pipe 3, in this embodiment, the water inlet pipe 3 is a straight circular pipe, the axis of the water inlet pipe 3 is perpendicular to the axis of the water outlet pipe 1, and the two ends of the water inlet pipe 3 are respectively A end and B end. The Y end of the elbow joint 2 is sleeved on the B end of the water inlet pipe 3, the A end of the water inlet pipe 3 is at the upper end of the horizontal plane M where the axis of the water outlet pipe 1 is located, and the water inlet pipe 3 is fixedly connected to the elbow joint 2. The water inlet pipe 3 and the elbow joint 2 can rotate around the axis of the water outlet pipe 1 as a whole. The inner diameter of the water inlet pipe 3 is equal to the inner diameter of the water outlet pipe 1.

[0035] A plurality of bearings 4 are sleeved on the water outlet pipe 1. In this embodiment, there are two bearings 4, which are arranged in parallel along the axis of the water outlet pipe 1. The inner rings of the two bearings 4 are fixedly connected to the water outlet pipe 1.

[0036] The sleeve 5 is a straight round tube in this embodiment. The sleeve 5 is sleeved on a plurality of bearings 4. The axis of the sleeve 5 coincides with the axis of the outlet pipe 1. Two bearings 4 are located at both ends of the sleeve 5. The sleeve 5 is fixedly connected to the outer rings of the plurality of bearings 4. The sleeve 5 is also fixedly connected to the elbow joint 2. Therefore, the water inlet pipe 3, the elbow joint 2, and the sleeve 5 as a whole can rotate around the axis of the outlet pipe 1 by relying on the bearings 4.

[0037] It also includes a driving assembly for driving the water inlet pipe 3, the elbow joint 2, and the sleeve 5 to rotate as a whole, and the driving assembly includes:

[0038] Support 7, installed on the ridge;

[0039] The non-rotating shaft end of the motor 9 is mounted on the support 7 , and the rotating shaft of the motor 9 is parallel to the axis of the water outlet pipe 1 .

[0040] The driving gear 8 is fixedly connected to the rotating shaft of the motor 9, and the axis of the driving gear 8 coincides with the axis of the motor 9;

[0041] The driven gear 6 is sleeved on the sleeve 5 and fixedly connected to the sleeve 5. The axis of the driven gear 6 coincides with the axis of the sleeve 5, and the driven gear 6 meshes with the driving gear 8. The motor 9 drives the driving gear 8 to rotate. Since the driving gear 8 meshes with the driven gear 6, the driving gear 8 drives the driven gear 6 to rotate. The driven gear 6, the sleeve 5, the elbow joint 2, and the water inlet pipe 3 can rotate around the axis of the water outlet pipe 1 as a whole.

[0042] The use process of this drainage pipe is:

[0043] First, the user determines the maximum water level in the paddy field based on seasonal changes and experience. Then, the user sends control information to the motor 9 through a terminal, such as a host computer, through a 5G sending module. The control information includes the direction and rotation angle of the motor 9 to ensure that the motor 9 can make the A end of the water inlet pipe 3 reach the appropriate position;

[0044] Specifically, the controller of the motor 9 is equipped with a 5G receiving module, which can receive the sent control information. The controller of the motor 9 sends a control instruction to the motor 9 according to the control information, and the motor completes the corresponding action. The motor 9 adopts a DC servo motor and is powered by an external battery.

[0045] After the motor 9 receives the command from the controller, the motor 9 rotates, and the motor 9 drives the driving gear 8 to rotate. Since the driving gear 8 is meshed with the driven gear 6, the driving gear 8 drives the driven gear 6 to rotate. The driven gear 6, the sleeve 5, the elbow joint 2, and the water inlet pipe 3 as a whole rotate around the axis of the water outlet pipe 1 by the bearing 4. Therefore, the distance H from the A end of the water inlet pipe 3 to the horizontal plane M where the axis of the water outlet pipe 1 is located will change, because the maximum water level in the rice field is equal to the aforementioned H. Therefore, by rotating the driven gear 6, the sleeve 5, the elbow joint 2, and the water inlet pipe 3 as a whole around the axis of the water outlet pipe 1, the purpose of adjusting the maximum water level in the rice field is achieved to cater to seasonal changes.

[0046] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
