Description

TECHNICAL FIELD

[0001] The present application relates to the field of pipeline, especially to a broiler farm fire-fighting water supply and drainage pipe. BACKGROUND

[0002] The fire-fighting water supply and drainage system has a crucial strategic significance in broiler farming, and is a rigid demand for maintaining the sustainable development of the industry. It is used for supplying drinking water to ensure the growth and development of broilers, egg production (breeders or layers), and feed digestion and absorption. It is also used for maintaining environmental hygiene and biological safety, and adjusting the temperature and humidity of the farm. It is an indispensable infrastructure for the successful operation of modern intensive and large-scale broiler farms, the realization of profits, the protection of food safety, and the fulfillment of environmental protection responsibilities.

[0003] Due to the eutrophication of sewage (mainly feed, feces, oil and lint), foreign matter is easily attached to the inner wall of the drainage pipeline. Over time, it will affect the pipeline flow and interfere with the water supply and drainage system. The common method is to disassemble the pipeline or use a high-pressure spray head to clean the inner wall of the pipeline. However, these methods have disadvantages. The pipeline needs to be disassembled, and the water flow needs to be stopped to achieve pipeline cleaning, which will affect the normal operation of the water supply and drainage system. The purpose of the present application is to propose a new pipeline structure to solve the above technical problems. SUMMARY

[0004] The purpose of the present application is to provide a broiler farm fire-fighting water supply and drainage pipe to solve the problems mentioned in the background.

[0005] To achieve the above object, the present application provides the following technical scheme: including the main body, the inner ring, the outer ring and the driving device, the inner ring is arranged in the main body for cleaning the inner wall of the main body, the inner ring includes the movable ring, the fixed ring and the magnet block, the fixed ring is embedded with the roller abutting against the inner wall of the main body, the movable ring is embedded with the ball forming a spherical pair with the movable ring, the fixed ring is located at the end of the movable ring and forms a rotary pair with the movable ring, the ball abuts against the inner wall of the main body, the magnet block is installed on the movable ring, the magnet block is connected with the movable ring through the telescopic rod, the telescopic rod is sleeved with the spring, and the telescopic rod is telescopic under the cooperation of the magnet and the spring, which is arranged to make the magnet block movable and avoid the accumulation of foreign matters at the magnet block. The telescopic rod refers to a rod body that can be telescopic and variable in length, which belongs to the prior art, so its specific structure and working principle will not be described in detail. The inner side of the movable ring is provided with an elastic protective sleeve, the two ends of the elastic protective sleeve are respectively matched with the inner side of the movable ring, the inner side of the elastic protective sleeve is connected with the magnet block, and a polytetrafluoroethylene coating is arranged on the surface of the elastic protective sleeve. The elastic protective sleeve refers to a sleeve-shaped component made of elastic material for protection. The purpose of arranging the polytetrafluoroethylene coating is to improve the corrosion resistance, and the low surface friction coefficient of polytetrafluoroethylene helps to avoid the attachment of foreign matters. Therefore, the specific elastic material is not an essential technical feature and is not the technical content to be protected by the applicant, so it will not be further explained and described. The skilled person can select a suitable elastic material according to the actual needs in the implementation, which will not have a substantial impact on the technical effect. The outer ring is sleeved on the outer side of the main body, the electromagnet is installed on the outer ring, and the electromagnet is attracted to the magnet block after being electrified. The driving device is used to drive the outer ring to rotate on the outer side of the main body.

[0006] To optimize the above technical scheme, the following measures are further taken: the driving device includes a gear ring, a clamping groove and a servo motor, the gear ring is arranged on the side surface of the outer ring, the outer ring forms annular clamping blocks at the front and rear ends, the clamping groove is matched with the annular clamping blocks to form a rotary pair, the clamping grooves are connected through a base, the servo motor is fixed with the clamping groove, a gear is arranged on the rotating shaft of the servo motor and engaged with the gear ring, and the driving effect is realized through the cooperation of the above components to drive the outer ring to rotate on the outer side of the main body.

[0007] As a further improvement of the above technical scheme: the outer side of the fixed ring is annularly arrayed with first blades, the outer side of the movable ring is annularly arrayed with second blades, the length direction of the first blades is parallel to the length direction of the main body, the length direction of the second blades is inclined and not parallel to the length direction of the first blades, the first blades are wedge-shaped, and the main body is cleaned through the cooperation of the first blades and the second blades. The non-parallel design of the first blades and the second blades helps to separate the cleaned foreign matters, thereby reducing the size of the foreign matters and avoiding pipeline blockage.

[0008] As a further improvement of the technical solution: the magnet blocks are distributed at equal intervals on the movable ring, and the number and position of the magnet blocks correspond to the number and position of the electromagnets on the outer ring, which is arranged to ensure that the electromagnets can cooperate with the magnet blocks, thereby realizing the effect of driving the inner ring to passively rotate by the active rotation of the outer ring.

[0009] As an improvement of the foregoing technical solution: the rollers are arranged at equal intervals on the fixed ring and roll along the length direction of the main body, which is designed to suppress the rotation of the fixed ring during the movement of the inner ring, and to avoid the synchronous rotation of the fixed ring and the movable ring affecting the separation effect of the first blade and the second blade on foreign matter.

The induction heating coil heats the main body by induction heating, which is designed to soften the grease and foreign matter attached to the inner side of the main body by heating. The foamed aluminum ring refers to a ring-shaped component made of foamed aluminum, which has heat insulation and electromagnetic shielding effects, and is arranged to suppress the influence of the induction heating coil on the electromagnet during operation.

[0011] Preferably, it further comprises a linear motor, which is located below the main body. The moving part of the linear motor is connected with the outer ring and can drive the outer ring to move along the length direction of the main body. The linear motor can drive the outer ring to move, which is designed to improve the automation degree of the equipment and help to improve the work efficiency.

[0012] From the above description of the structure of the present application, compared with the prior art, the present application has the following advantages:

[0013] Without disassembling the pipeline and stopping the water flow, the inner wall of the main body can be cleaned. The outer ring and the inner ring cooperate with each other to clean the inner wall of the main body, which can avoid the influence of cleaning operation on water supply and drainage;

[0014] The movable ring and the fixed ring on the inner ring cooperate with each other to clean the inner wall of the main body, which not only can effectively clean the foreign matter but also can cut the foreign matter into pieces by the first blade and the second blade, which can avoid the blockage of the main body by the agglomeration of foreign matter and affect the drainage;

[0015] By impacting the elastic protective sleeve with the magnet block, the foreign matter can be prevented from adhering to the inner side of the inner ring. In addition, the induction heating coil can also heat and soften the foreign matter, which can reduce the difficulty of cleaning the foreign matter and help to separate the foreign matter from the main body.

[0016] The inner ring and the outer ring are independent of each other, and the electrical components are concentrated on the outside of the main body, which is convenient for maintenance and repair. BRIEF DESCRIPTION OF DRAWINGS

[0048] The control mode of the present application is realized by an external controller to realize automatic control, and the control circuit of the controller can be realized by simple programming of those skilled in the art, and the power supply also belongs to the common knowledge in the art, and the present application is mainly used to protect the mechanical device, so the control mode and circuit connection of the present application will not be explained in detail.

[0049] Working principle: for examples 1-3, the driving device 4 can drive the outer ring 3 to rotate through the meshing of the gear 406 and the gear ring 401, and since the electromagnet 301 and the magnet block 203 attract each other, the movable ring 201 is driven by the outer ring 3 to clean the foreign matter attached to the inner wall of the main body 1 under the action of the attraction force, so as to avoid the influence of the foreign matter attached to the inner wall of the main body 1 on the flow, and the cleaning of the foreign matter on the inner wall of the main body 1 can be realized without disassembling the pipeline and stopping the water flow.

[0050] In addition, since the electromagnet 301 and the magnet block 203 attract each other, for the skilled person of example 1, the outer ring 3 can be manually pushed on the main body 1 to change the position of the outer ring 3 on the main body 1, and for the skilled person of examples 2 and 3, the outer ring 3 can be driven by the linear motor 7 to change the position of the outer ring 3 on the main body 1, since the electromagnet 301 on the outer ring 3 and the magnet block 203 on the inner ring 2 attract each other, the inner ring 2 will move with the movement of the outer ring 3, so as to clean the foreign matter located at different positions on the inner wall of the main body 1, and in the actual use process, the skilled person can also change the current size, current frequency, coil quantity and other factors to improve the magnetism of the electromagnet 301, so as to enhance the attraction between the electromagnet 301 and the magnet block 203.

[0051] For examples 1-3, the first blade 206 on the fixed ring 202 can cut the foreign matter attached to the inner wall of the main body 1 during the rotation and movement of the inner ring 2, and the movable ring 201 with the second blade 207 is affected by the magnet block 203 and the electromagnet 301, so that the second blade 207 can cut the foreign matter cut by the first blade 206 again, and the staggered and non-parallel first blade 206 and second blade 207 cooperate with each other, which not only helps to improve the cleaning effect of the foreign matter on the inner wall of the main body 1, but also avoids that the size of the cleaned foreign matter is too large to affect the flow.

[0052] For the embodiment 2 and 3, the induction heating coil 5 can move synchronously with the outer ring 3, and the induction heating coil 5 can heat the main body 1 during the movement. Since the induction heating coil 5 is located at the end of the outer ring 3, the induction heating coil 5 will not heat the inner ring 2 and cause damage to the inner ring 2. By heating the main body 1, the grease and foreign matter attached to the inner wall of the main body 1 can be softened and separated from the main body 1. Since the foamed aluminum ring 6 is arranged between the induction heating coil 5 and the outer ring 3, the foamed aluminum ring 6 can play a role of heat insulation and electromagnetic shielding, and can inhibit the influence of the induction heating coil 5 on the electromagnet 301 during the operation of the induction heating coil 5.

[0053] For the embodiments 1-3, when the electromagnet 301 and the magnet block 203 attract each other, the magnet block 203 will press the spring 209 and the telescopic rod 208. After the electromagnet 301 is powered off, the spring 209 and the telescopic rod 208 will return to the original position. When the spring 209 and the telescopic rod 208 return to the original position, the magnet block 203 can impact the elastic protective sleeve 2010, and the foreign matter attached to the surface of the elastic protective sleeve 2010 can be prevented from affecting the flow of the main body 1.
