Description

Technical Field

[0001] The invention relates to the technical field of grain storage, and in particular to an electric wiring device for a grain bin. Background Art

[0002] Food is the primary material basis for a country's stability. As a country with a large population, my country needs to store a considerable amount of food. If the food cannot be properly stored, it will lead to a large amount of food waste. According to statistics, my country's annual grain storage is nearly 1 billion tons, and the loss rate is about 3% to 4%. Although the proportion is small, the huge amount causes huge asset losses every year.

[0003] Since 2014, China National Grain Reserves Corporation has launched an intelligent grain silo improvement project for scientific grain storage. Through intelligent grain silo control, the loss rate can be reduced to below 1%, saving the country more than 20 billion kilograms of grain and nearly 10 billion yuan in funds each year.

[0004] In the process of intelligent granary monitoring, temperature measurement and temperature control are the most basic solutions. Only by fully covering the temperature monitoring inside the granary can the intelligent adjustment of the granary be realized to avoid the deterioration and loss of grain caused by local temperature anomalies. However, it is difficult to achieve comprehensive temperature monitoring inside the granary. The traditional point temperature measurement has a small coverage area, and infrared temperature measurement cannot determine the center temperature of the warehouse pile. New technologies are needed for distributed temperature monitoring. In recent years, with the development of fiber optic sensing technology, due to the characteristics of optical fiber such as small radial size, easy bending, and non-electrified measurement, it is more suitable for the application environment of temperature measurement inside the granary.

[0005] However, optical fiber is relatively soft, and the depth of a grain pile is generally 6 meters. How to evenly arrange the optical fiber inside the grain pile is an important issue for the successful application of optical fiber sensing technology. In order to evenly arrange the temperature measurement optical fiber inside the grain silo, it is necessary to adopt a wiring method that is suitable for the silo and a dedicated wiring device. Summary of the invention

[0006] In order to solve the defects of the prior art, the present invention proposes an electric wiring device for a granary, which realizes the automatic laying of optical fibers in the granary.

[0007] To achieve the above-mentioned purpose, an electric wiring device for a granary of the present invention comprises: a driving part, an optical fiber bearing part, and a linkage mechanism. The driving part comprises a rod and an electric digging module. The electric digging module is connected to one end of the rod, and comprises a shell, a motor, a power transmission mechanism, and a digging mechanism. The motor drives the digging mechanism to move through the power transmission mechanism, and then drives the electric digging module to move downward toward the interior of the granary pile; the optical fiber bearing part contains optical fibers to be laid in the granary pile; the linkage mechanism connects the driving part and the optical fiber bearing part; when the electric digging module moves downward toward the interior of the granary pile, the driving part drives the optical fiber bearing part to move toward the interior of the granary pile through the linkage mechanism, and when the electric digging module moves upward in the opposite direction, the linkage mechanism automatically disengages from the optical fiber bearing part.

[0008] In one embodiment, the linkage mechanism includes a linkage rod and a slot. One end of the linkage rod is connected to the electric excavation module, and the other end is provided with a hook that cooperates with the slot. The slot is arc-shaped and formed on the optical fiber bearing part. The slot extends from one side of the optical fiber bearing part toward the other side and downward.

[0009] In one embodiment, the power transmission mechanism includes a first transmission gear, a second transmission gear, and a third transmission gear. The first transmission gear is connected to the motor shaft of the motor. The second transmission gear and the third transmission gear are arranged side by side and mesh with each other. The first transmission gear meshes with the second transmission gear or the third transmission gear.

[0010] In one embodiment, the excavation mechanism includes a pair of crawler assemblies, which are symmetrically arranged about the longitudinal center line of the driving part and arranged in an inverted eight shape, so that the shell has a shape that is wide at the top and narrow at the bottom, and the outer sides of the crawlers of the pair of crawler assemblies protrude from the shell respectively.

[0011] In one embodiment, a pair of track assemblies have the same structure, both including a track, an upper pulley, and a lower pulley. The track is meshed with the upper pulley and the lower pulley. The second transmission gear and the third transmission gear are respectively connected to the upper pulleys of the pair of track assemblies to drive the upper pulleys to rotate.

[0012] In one embodiment, the tracks of a pair of track assemblies rotate in opposite directions, and the diameter of the upper pulley is larger than that of the lower pulley.

[0013] In one embodiment, the electric tunneling module also includes a friction transmission mechanism, which includes a friction driving wheel and a friction driven wheel that cooperate with each other. The friction driving wheel is fixedly connected to the upper pulley of one of a pair of track assemblies, and the friction driven wheel is fixedly connected to the linkage rod.

[0014] In one embodiment, the power transmission mechanism and the friction transmission mechanism are respectively arranged on both sides of the excavation mechanism, and the second transmission gear, the upper pulley connected to the second transmission gear and the friction driving wheel are coaxial.

[0015] In one embodiment, when the electric excavation module moves downward toward the interior of the bin pile, the hook is located in the slot and the friction driven wheel is in a slipping state. When the electric excavation module moves upward in the opposite direction, the hook disengages from the slot.

[0016] Beneficial effects:

[0017] The electric wiring device of the present invention solves the problem in the prior art that optical fibers are difficult to bury in the warehouse pile. When the electric wiring device of the present invention is in use, the operator only needs to operate the controller so that the driving part drives the optical fiber bearing part to move toward the warehouse pile. During the laying process, the electric wiring device of the present invention can ensure that the optical fiber is laid in the vertical direction and will not be deformed. When the optical fiber bearing part moves to the desired position, the electric wiring device is pulled out of the warehouse pile, and the linkage mechanism that connects the driving part and the optical fiber bearing part automatically disengages from the optical fiber bearing part, so that the optical fiber bearing part remains in the warehouse pile, thereby realizing the automatic laying of optical fibers in the warehouse pile. The electric wiring device of the present invention has a clever structural design and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solution of the present invention will be more clearly and completely explained below through description of preferred embodiments of the present invention in combination with the accompanying drawings.

[0025] like Figures 1 to 3As shown, an electric wiring device for a granary according to a preferred embodiment of the present invention comprises a driving part 1, an optical fiber bearing part 2, and a linkage mechanism 3. The linkage mechanism 3 connects the driving part 1 and the optical fiber bearing part 2. The optical fiber bearing part 2 is used to carry the optical fiber to be laid, and comprises a rod and a bottom, and the optical fiber is arranged inside the optical fiber bearing part 2. The linkage mechanism 3 is connected between the driving part 1 and the bottom of the optical fiber bearing part 2. The driving part 1 drives the optical fiber bearing part 2 to move toward the inside of the granary through the linkage mechanism 3, so that the optical fiber is laid in the granary.

[0026] The driving part 1 includes a rod 11 and an electric excavation module 12. The electric excavation module 12 is installed at one end of the rod 11 to provide power for the wiring operation. The rod 11 is assembled and connected by multiple sections of rods 110. In this embodiment, the rod 11 is assembled by 4 sections of rods, each section of the rod is 1.6 meters. Each section of the rod 110 is a hollow structure, so that the control line of the electric excavation module 12 extends from the bottom end of the rod 11 to the top end, and the controller 13 is connected at the top end, so that the operator can control the movement of the electric excavation module 12 by operating the controller 13.

[0027] like Figures 2 to 5 As shown, the electric excavation module 12 includes a housing 120, a motor 121, a power transmission mechanism 122, and an excavation mechanism 123. The motor 121, the power transmission mechanism 122, and the excavation mechanism 123 are arranged in the housing 120, wherein the excavation mechanism 123 is located at the lower part of the housing 120, and the motor 121 is located at the upper part of the housing 120. The motor 121 drives the excavation mechanism 123 to move through the power transmission mechanism 122.

[0028] In this embodiment, a battery 124 is further disposed in the housing 120 for supplying power to the motor 121. In other embodiments, the motor 121 may also be supplied with power in other ways, not limited to battery supply.

[0029] The power transmission mechanism 122 includes a first transmission gear 1221, a second transmission gear 1222, and a third transmission gear 1223. The first transmission gear 1221 is connected to the motor shaft of the motor 121 and is driven to rotate by the motor 121. The second transmission gear 1222 and the third transmission gear 1223 are arranged side by side below the first transmission gear 1221, and the two are meshed with each other. The rotation axes of the first transmission gear 1221, the second transmission gear 1222, and the third transmission gear 1223 are parallel to each other. The first transmission gear 1221 is meshed with one of the second transmission gear 1222 and the third transmission gear 1223, and is used to transmit power to the second transmission gear 1222 or the third transmission gear 1223. In this embodiment, the first transmission gear 1221 is meshed with the second transmission gear 1222, driving the second transmission gear 1222 to rotate, and the second transmission gear 1222 is meshed with the third transmission gear 1223, and then the motion is transmitted to the third transmission gear 1223, driving the third transmission gear 1223 to rotate.

[0030] The excavation mechanism 123 includes a pair of track assemblies, which are symmetrically arranged about the longitudinal center line of the driving part 1 and are arranged in an inverted eight shape, so that the shell 120 has a shape that is wide at the top and narrow at the bottom, and the bottom of the shell 120 is arc-shaped. This shape design can reduce the resistance of the electric excavation module 12 when it moves toward the inside of the warehouse pile.

[0031] A pair of crawler assemblies have the same structure, both including crawler 1230, upper pulley 1231, and lower pulley 1232, and crawler 1230 is meshed with upper pulley 1231 and lower pulley 1232. The diameter of upper pulley 1231 is larger than that of lower pulley 1232. Since the crawler assembly is arranged in an inverted eight-shaped shape, the line connecting the center of upper pulley 1231 to the center of lower pulley 1232 is inclined with respect to the longitudinal center axis of driving part 1, that is, lower pulley 1232 is closer to the longitudinal center axis of electric tunneling module 12 than upper pulley 1231, and accordingly, crawler 1230 is arranged in an inclined direction. Both sides of housing 120 are provided with openings near crawler assembly, so that the outer sides of two crawlers 1230 protrude from the openings and can move in the warehouse pile.

[0032] The track assembly is driven by the power transmission mechanism 122. Specifically, the second transmission gear 1222 and the third transmission gear 1223 are respectively connected to the upper pulleys 1231 of a pair of track assemblies, driving the upper pulleys 1231 to rotate. The upper pulley 1231 drives the lower pulley 1232 to rotate through the track 1230. Since the second transmission gear 1222 and the third transmission gear 1223 are externally meshed gear transmissions, their rotation directions are opposite, and accordingly, the rotation directions of the two upper pulleys 1231 are opposite, and the rotation directions of the two tracks 1230 are also opposite.

[0033] The electric excavation module 12 also includes a friction transmission mechanism 125, which is located on both sides of the excavation mechanism 123 with the power transmission mechanism 122. Specifically, the friction transmission mechanism 125 includes a friction driving wheel 1251 and a friction driven wheel 1252 that cooperate with each other, wherein the friction driving wheel 1241 is connected to one of the upper pulleys 1231, driven to rotate by the upper pulley 1231, and the friction driving wheel 1251 cooperates with the friction driven wheel 1252 to transmit power to the friction driven wheel 1252. In this embodiment, the friction driving wheel 1251 is coaxial with the second transmission gear 1222 and the upper pulley 1231, and the friction driving wheel 1251 and the second transmission gear 1222 are respectively arranged on both sides of the upper pulley 1231, so that the electric excavation module 12 has a compact structure and a small size, which is convenient for movement in the warehouse pile. The friction force of the friction transmission mechanism 125 is about 10N. When the external stopping force is greater than 10N, the friction driven wheel 1252 slips and does not rotate with the friction driving wheel 1251.

[0034] The linkage mechanism 3 includes a linkage rod 31 and a slot 32. One end of the linkage rod 31 is connected to the friction driven wheel 1252, and the other end is provided with a hook 310. The slot 32 is formed on the optical fiber bearing part 2, preferably, located at the bottom of the optical fiber bearing part 2. The slot 32 is an arc-shaped slot, which extends from one side of the optical fiber bearing part 2 to the other side and downward. When laying optical fibers in the warehouse stack, the hook 310 is inserted into the slot 32, thereby establishing a linkage relationship between the driving part 1 and the optical fiber bearing part 2.

[0035] The working principle of the electric wiring device of the present invention is as follows:

[0036] When it is necessary to lay optical fiber into the grain silo, the driving part 1 and the optical fiber bearing part 2 are placed roughly parallel to each other, and then the hook 310 of the linkage rod 31 is inserted into the slot 32, the motor 121 is turned on, and the rod 11 is held by hand. The motor 121 drives the excavation mechanism 123 to move through the power transmission mechanism 122, and a pair of crawler assemblies of the excavation mechanism 123 rotate, driving the electric excavation module 12 and the entire driving part 1 to move downward. At the same time, the excavation mechanism 123 drives the friction transmission mechanism 125, and the friction driven wheel 12 52 rotates and transmits power to the linkage rod 31, and the linkage rod 31 transmits power to the optical fiber bearing part 2 through the cooperation of the hook 310 and the slot 32. When the resistance encountered by the linkage rod 31 and the friction transmission mechanism 125 is greater than 10N, the friction driven wheel 1252 slips, but continues to transmit downward power to the linkage rod 31, and the linkage rod 31 drives the optical fiber bearing part 2 to move downward. Therefore, under the drive of the electric excavation module 12, the optical fiber bearing part 2 moves downward toward the inside of the warehouse pile together with the driving part 1.

[0037] When the optical fiber bearing part 2 moves downward to the desired position, the operator first operates the controller 13 to reverse the motor 121, and the motor 121 drives the excavation mechanism 123 to rotate in the opposite direction. The excavation mechanism 123 drives the linkage rod 31 to rotate in the opposite direction through the friction transmission mechanism 125, so that the hook 310 rotates out of the slot 32. At this time, the driving part 1 is pulled out upward, and the optical fiber bearing part 2 is left in the warehouse pile, completing the optical fiber laying operation. The optical fiber senses the temperature, humidity, vibration, etc. in the warehouse pile, thereby realizing intelligent monitoring of the grain in the warehouse pile.

[0038] The above specific implementations are only descriptions of the preferred implementations of the present invention, and do not limit the protection scope of the present invention. Without departing from the design concept and spirit of the present invention, various modifications, substitutions and improvements made by ordinary technicians in this field to the technical solution of the present invention based on the text description and drawings provided by the present invention should all fall within the protection scope of the present invention. The protection scope of the present invention is determined by the claims.
