Description

Technical Field

[0001] This utility model belongs to the field of agricultural irrigation technology, specifically relating to an anti-freezing and cracking sprinkler pipe structure for agricultural irrigation. Background Technology

[0002] Freezing prevention measures for sprinkler irrigation pipelines are crucial to ensuring the safe operation of irrigation systems in winter. Depending on the type of sprinkler irrigation system and climatic conditions, methods such as manual drainage, automatic drainage, compressed air drainage, or wrapping the pipeline with antifreeze materials can be selected. Reasonable antifreeze design and daily management can significantly reduce the risk of frost damage and lay the foundation for agricultural production in the following year.

[0003] Currently, in the process of antifreeze treatment for sprinkler irrigation pipes used in agricultural irrigation, the common practice is to manually coil antifreeze material around the outer wall of the pipe exposed to the external environment. This wraps the pipe wall with material to reduce the damage caused by low temperatures. However, this method is limited by the cylindrical shape of the pipe and requires frequent repetition of the coiling action. When there are a large number of pipes to be treated, the operation becomes extremely cumbersome. Furthermore, the manual coiling process can easily lead to uneven coverage of the insulation material on the outer wall of the pipe or gaps between the materials, causing some pipe sections to be directly exposed to the external environment. This results in a significant decrease in the antifreeze effect and is extremely inconvenient. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a structure for an anti-freezing and crack-resistant sprinkler pipe for agricultural irrigation. This addresses the issue raised in the background section where, in the current anti-freezing treatment of sprinkler pipes for agricultural irrigation, anti-freezing material is typically manually coiled around the outer wall of the pipe exposed to the external environment. This material wraps around the pipe wall to reduce low-temperature damage. However, this method is limited by the cylindrical pipe shape, requiring frequent repetition of the coiling action. When dealing with a large number of pipes, the operation becomes extremely cumbersome. Furthermore, the manual coiling process easily leads to uneven coverage of the insulation material on the outer wall of the pipe or gaps between the materials, causing some sections of the pipe to be directly exposed to the external environment, resulting in a significant decrease in anti-freezing effectiveness and causing considerable inconvenience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a frost-resistant sprinkler irrigation pipe structure for agricultural irrigation, comprising a main body and an integrated insulation mechanism disposed outside the main body, which, through integral stretching, uniformly wraps the insulation material onto the outer wall of the pipe in one go, simplifying the operation process and ensuring the frost-resistant effect. The integrated insulation mechanism includes diaphragms symmetrically arranged on the outside of the sprinkler irrigation pipe, movably connected to the diaphragms. An outer ring is fixedly connected to the outside of the diaphragms. Side frames are symmetrically arranged on the outside of the outer ring. A pusher screw is threadedly connected to the inside of the side frames. A base is rotatably connected to the outside of one end of the pusher screw. A pusher plate is fixedly connected to one side of the base. A clamping pad is fixedly connected to one side of the pusher plate. A connecting hose is fixedly connected to one side of the outer ring. An outer insulation folding hose is fixedly connected between adjacent connecting hoses. An inner insulation folding hose is fixedly connected to the inside of the outer insulation folding hose.

[0006] Preferably, the main body includes a buried pipe, one end of which is fixedly connected to an elbow, and the top of the elbow is fixedly connected to a sprinkler pipe.

[0007] Preferably, a knob is fixedly connected to one end of the advancing screw, and a side frame is threadedly connected to the outer side of the advancing screw.

[0008] Preferably, a pinch pad is fixedly connected to the outside of the knob. The pinch pad is made of flexible material, and several grooves are symmetrically arranged on the outer surface of the pinch pad.

[0009] Preferably, a spring is movably connected to the outer side of one end of the abutting screw, and the spring is located between the side frame and the knob.

[0010] Preferably, a slide rod is fixedly connected to one side of the push plate, and several slide rods are symmetrically arranged. A side frame is slidably connected to the outside of the slide rod, and an outer ring is fixedly connected to one side of the side frame.

[0011] Preferably, a hook is fixedly connected to one side of the adapter hose, and several hooks are symmetrically arranged, with the outer surface of the hooks being treated with a deburring process.

[0012] Preferably, the clamping pad is made of a flexible material, the clamping pad has an arc-shaped structure, and a pusher is fixedly connected to one side of the clamping pad.

[0013] Compared with the prior art, this utility model provides a structure for an anti-freezing and cracking sprinkler irrigation pipe for agricultural irrigation, which has the following beneficial effects:

[0014] 1. This utility model uses an internally insulated folding flexible hose to bury a pipe of the required length in an agricultural planting area. One end of the hose is connected to a valve body connected to a water source. The sprinkler head is then connected to the top of the irrigation pipe. Under normal temperature conditions, the integrated insulation mechanism retracts to the outer wall of the bottom of the irrigation pipe. The integrated insulation mechanism is fixed in a retracted state to the outer wall of the bottom of the irrigation pipe by the pressure of the clamping pad on one side of the push plate. When the temperature drops, the knob at the top is squeezed counterclockwise to engage the screw, causing the screw to move outward from the inside of the side frame. This disengages the clamping pad on the push plate from the pressure on the outer wall of the irrigation pipe, releasing the restriction on the outer ring position. Then, the side frame is lifted by holding the outer wall of the upper side frame, allowing the outer ring and the spacer to slide on the outer wall of the irrigation pipe to the required protection height. During the upward movement of the side frame, the outer... Due to their structure and materials, the thermal insulation folding hose and the inner thermal insulation folding hose can extend and move upward synchronously through deformation, so that the inner and outer thermal insulation folding hoses completely cover the exposed part of the sprinkler pipe in the external environment. Then, the screw is rotated clockwise inside the upper side frame, driving the screw to move the push plates on both sides towards the center until they are fully clamped between the pads to secure the outer wall of the sprinkler pipe. The upper side frame is then fixed, completing the installation of the thermal insulation material on the outer wall of the sprinkler pipe. This can ensure the pipe's antifreeze capability while reducing the need for manual coiling of the insulation material on the outer wall of the pipe. It simplifies the operation process and reduces the physical exertion of personnel. It also reduces the possibility of uneven insulation material thickness or gaps between materials during manual coiling, which could expose part of the outer wall of the pipe to the external environment and reduce the antifreeze effect.

[0015] 2. By setting a knob, this utility model can effectively facilitate personnel to directly pinch and rotate the screw without the aid of external tools, thus improving the convenience of operation;

[0016] 3. By incorporating a spring and using the spring to support the knob in the opposite direction, this utility model can effectively reduce the loosening caused by the screw fixed to one side of the knob during long-term use.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This utility model provides a technical solution: a frost-resistant sprinkler irrigation pipe structure for agricultural irrigation, including a main body 1 and an integrated insulation mechanism 2 disposed outside the main body 1. This integrated insulation mechanism 2, through integral stretching, uniformly wraps the insulation material onto the outer wall of the pipe in one go, simplifying the operation process and ensuring the frost-resistant effect. The integrated insulation mechanism 2 includes septa 201 symmetrically arranged on the outside of the sprinkler irrigation pipe 103, movably connected to the septa 201. An outer ring 202 is fixedly connected to the outside of the septa 201. Side frames 203 are symmetrically arranged on the outside of the outer ring 202. A threaded screw 204 is threaded onto the inner side of the side frame 203. A base 205 is rotatably connected to the outer side of one end of the threaded screw 204. A push plate 206 is fixedly connected to one side, a clamping pad 207 is fixedly connected to one side of the push plate 206, an adapter hose 208 is fixedly connected to one side of the outer ring 202, an outer insulated folded hose 209 is fixedly connected between adjacent adapter hoses 208, and an inner insulated folded hose 210 is fixedly connected to the inner side of the outer insulated folded hose 209. The required length of the buried pipe 101 is buried in the agricultural planting site, and one end of it is connected to the valve body connected to the water source. Then, the sprinkler head required for irrigation is connected to the top of the irrigation pipe 103. Under normal temperature conditions, the integrated insulation mechanism 2 retracts into the outer wall of the bottom end of the irrigation pipe 103, and the water flow is controlled by the push plate 206. The clamping pad 207 presses against the outer wall of the irrigation pipe 103, causing the integrated insulation mechanism 2 to be fixed in a retracted state to the outer wall of the bottom end of the irrigation pipe 103. When entering the low-temperature season, directly pinch the knob 3 located at the top and rotate it counterclockwise to engage the screw 204, causing the screw 204 to move outward from the inside of the side frame 203. This causes the clamping pad 207 on one side of the push plate 206 to disengage from the state of pressing against the outer wall of the irrigation pipe 103, releasing the restriction on the position of the outer ring 202 located at the top. Then, holding the outer wall of the side frame 203 located at the top, lift the side frame 203, causing the outer ring 202 and the spacer 201 to slide on the outer wall of the irrigation pipe 103 to the required protection height. 3. During the upward movement, the outer insulation folded hose 209 and the inner insulation folded hose 210, due to their structure and material, can extend and move upward synchronously through deformation, so that the inner insulation folded hose 210 and the outer insulation folded hose 209 completely cover the exposed part of the sprinkler pipe 103 in the external environment. Then, the screw 204 is rotated clockwise inside the upper side frame 203, driving the screw 204 to move the push plates 206 on both sides towards the center until they are fully clamped between the clamping pads 207, thus fixing the upper side frame 203 and completing the installation of the insulation material on the outer wall of the sprinkler pipe 103.

[0026] In this utility model, preferably, the main body mechanism 1 includes a buried pipe 101, one end of which is fixedly connected to an elbow 102, and the top end of the elbow 102 is fixedly connected to a sprinkler pipe 103. A buried pipe 101 of sufficient length is buried in the agricultural planting site, and one end of it is connected to a valve body connected to a water source. The nozzles required for sprinkler irrigation are installed on the top of the sprinkler pipe 103. After opening the valve body, the water source from the buried pipe 101 is discharged into the elbow 102 and introduced into the nozzles through the sprinkler pipe 103 for sprinkler irrigation.

[0027] In this utility model, preferably, a knob 3 is fixedly connected to one end of the abutting screw 204, and a side frame 203 is threadedly connected to the outside of the abutting screw 204, which can effectively facilitate personnel to directly pinch and rotate the abutting screw 204 without the aid of external tools, thus improving the convenience of operation.

[0028] In this utility model, preferably, a pinch pad 4 is fixedly connected to the outside of the knob 3. The pinch pad 4 is made of flexible material, and several grooves are symmetrically arranged on the outer surface of the pinch pad 4. This can ensure the comfort of pinching while increasing friction and reducing the risk of slipping out of the hand.

[0029] In this utility model, preferably, a spring 5 is movably connected to the outer side of one end of the abutting screw 204. The spring 5 is located between the side frame 203 and the knob 3. By supporting the knob 3 in the opposite direction by the spring 5, the loosening caused by the abutting screw 204 fixed on one side of the knob 3 during long-term use can be effectively reduced.

[0030] In this utility model, preferably, a sliding rod 6 is fixedly connected to one side of the push plate 206, and several sliding rods 6 are symmetrically arranged. A side frame 203 is slidably connected to the outside of the sliding rod 6, and an outer ring 202 is fixedly connected to one side of the side frame 203, which can effectively ensure the stability of the position of the push plate 206 and the clamping pad 207 during movement and clamping.

[0031] In this utility model, preferably, a hook ring 7 is fixedly connected to one side of the adapter hose 208. Several hook rings 7 are symmetrically arranged. The outer surface of the hook ring 7 is treated with a deburring process. By inserting the cable tie into the hook ring 7 and tightening it, the adapter hose 208 is deformed, which increases the force of the inner wall of the adapter hose 208 pressing against the outer wall of the irrigation pipe 103, ensuring the sealing degree between the adapter hose 208 and the irrigation pipe 103, and reducing the amount of external cold source seeping into the gaps.

[0032] In this utility model, preferably, the clamping pad 207 is made of flexible material and has an arc-shaped structure. A pusher 206 is fixedly connected to one side of the clamping pad 207, which can reduce the wear on the irrigation pipe 103 while making it fit the outer wall of the irrigation pipe 103 more closely.

[0033] The working principle and usage process of this utility model are as follows: In use, the required length of the buried pipe 101 is laid in the agricultural planting area, and one end is connected to the valve body connected to the water source. Then, the required sprinkler head is connected to the top of the sprinkler pipe 103. Under normal temperature conditions, the integrated insulation mechanism 2 retracts entirely onto the outer wall of the bottom end of the sprinkler pipe 103. The integrated insulation mechanism 2 is fixed to the sprinkler pipe 103 in a retracted state by the pressure of the clamping pad 207 on one side of the pusher 206 against the outer wall of the sprinkler pipe 103. When entering the low-temperature season, directly pinch the knob 3 located at the top and rotate it counterclockwise to push the screw 204 into place. This causes the screw 204 to move outward from the inside of the side frame 203, causing the clamping pad 207 on one side of the push plate 206 to disengage from the state of squeezing the outer wall of the irrigation pipe 103. This releases the restriction on the position of the outer ring 202 located at the top. Then, hold the outer wall of the side frame 203 located at the top and lift the side frame 203, allowing the outer ring 202 and the spacer 201 to slide on the outer wall of the irrigation pipe 103 to the required protection height. During the upward movement of the side frame 203, the outer insulated folded hose 209 and the inner insulated folded hose 210, due to their structure and material, can extend and move upward synchronously through deformation, so that the inner insulated folded hose 210 and the outer insulated folded hose 209 completely cover the exposed part of the sprinkler pipe 103 in the external environment. Then, the screw 204 is rotated clockwise inside the upper side frame 203, driving the screw 204 to move the push plates 206 on both sides towards the center and fill the gap between the clamps 207. The clamps hold the outer wall of the irrigation pipe 103 and fix the upper side frame 203 to complete the installation of the insulation material on the outer wall of the irrigation pipe 103. This can ensure the antifreeze capability of the pipe body while reducing the need for personnel to manually coil the insulation material around the outer wall of the pipe body. In addition to simplifying the operation process and reducing the physical consumption of personnel, it also reduces the possibility of parts of the outer wall of the pipe body being directly exposed to the external environment due to uneven thickness of the insulation material or gaps between the materials during manual coiling, which reduces the antifreeze effect of the pipe body.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
