Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power auxiliary equipment, and particularly relates to a pole fixing device for an agricultural drainage power meter box integrating anti-theft and anti-loose functions. BACKGROUND

[0002] As a basic industry of the national economy, irrigation and drainage in the field is a key link to guarantee the growth of crops and improve grain yield, and stable and reliable power supply is the core support for efficient operation of agricultural drainage equipment. In the conventional scene, the electric meter box is usually fixed to the wall of the building by standard connecting pieces such as expansion bolts, but the agricultural drainage area in the field is often far away from the residential building group, and there is generally no wall body for fixing, which leads to the fact that the electric meter box cannot be installed in the conventional way. In the field construction, the electric meter box is usually fixed to the existing electric pole in the field, and the specific method is to achieve the connection and fixation of the electric meter box and the electric pole by the simple method of winding with iron wire or binding with cable.

[0003] Although the above simple fixing method can temporarily solve the installation problem of the electric meter box, it exposes many serious defects in actual application. The primary problem is the instability of the installation structure and the lack of anti-loose performance. The field environment is complex and changeable, and is long-term affected by natural factors such as strong wind, heavy rain, and large temperature difference. The iron wire and the cable themselves have a certain elastic deformation characteristic, and are prone to relaxation under the repeated action of environmental stress. At the same time, mechanical operation vibration in the process of agricultural production, accidental touching by personnel and other human factors further aggravate the loosening risk of the fixing structure. Moreover, such simple fixing method has no anti-theft function at all, which becomes a high-incidence inducement for the theft of electric meters and associated power facilities. The position of the agricultural drainage electric meter box is relatively remote, and it is difficult for personnel to supervise, and the disassembly of the iron wire and the cable is extremely low, so that the criminal can easily destroy the fixing structure and steal the electric meter. SUMMARY

[0004] In order to make up for the above shortcomings, the present application provides a pole fixing device for an agricultural drainage power meter box integrating anti-theft and anti-loose functions, which aims to solve the problem of the lack of anti-loose performance and the lack of anti-theft function of the simple fixing method such as iron wire winding and cable binding when the agricultural drainage electric meter box is installed in the field, and to provide protection for the stable power supply of agricultural drainage equipment and help efficient development of agricultural production.

[0005] In order to achieve the above-mentioned target, the technical scheme adopted by the present application is as follows: The utility model provides an agricultural row electric meter box pole fixing device with theftproof and anti-loose functions, which comprises a theftproof box, a fixed arc-shaped plate fixedly connected to one side of the theftproof box, a moving arc-shaped plate provided on the side of the fixed arc-shaped plate away from the theftproof box, extension plates fixedly connected to the two ends of the fixed arc-shaped plate and the moving arc-shaped plate, main drive screws rotatably connected to the two sides of the fixed arc-shaped plate on the theftproof box, the main drive screws being rotatably connected to the extension plates at the two ends of the fixed arc-shaped plate and penetrating through the extension plates at the two ends of the fixed arc-shaped plate, and the main drive screws being threadedly connected to the extension plates at the two ends of the moving arc-shaped plate.

[0006] By rotating the main drive screw, the rotational motion is converted into linear motion through the threaded cooperation between the main drive screw and the extension plates of the moving arc-shaped plate, the moving arc-shaped plate is driven to move axially along the main drive screw to approach or move away from the fixed arc-shaped plate, and thus the encircling clamping of the electric pole with different diameters is realized; the extension plates of the fixed arc-shaped plate only serve as the rotating support of the main drive screw and do not move with the screw, thereby ensuring the stability of the fixed end during the clamping process. The simple fixing mode of traditional iron wire winding and cable binding is replaced, the controllable clamping force is realized through the mechanical screw transmission, the elastic relaxation caused by natural environment or human touch is avoided, the electric pole with a wider diameter range is adapted, and the universality is high; the extension plates not only provide stable support for the screw, but also provide an installation reference for the subsequent anti-loose limiting structure.

[0007] A rotating shaft is rotatably connected to the outer sides of the two main drive screws on the theftproof box, a limiting block is fixedly connected to the outer wall of the rotating shaft, two I-shaped rings are slidably connected to the rotating shaft, a limiting groove matched with the limiting block is formed in the inner wall of each I-shaped ring, a gear box is rotatably connected to the I-shaped groove in the outer wall of each I-shaped ring, a driving gear is installed on one of the I-shaped rings, a driven gear is engaged with each side of the driving gear, a lifting screw is fixedly connected to the side of each driven gear away from the driving gear, the lifting screw is rotatably connected to the gear box and penetrates through the gear box, a lifting block is threadedly connected to the outer wall of the lifting screw, a V-shaped block is fixedly connected to the side of the lifting block close to the extension plate, and the V-shaped blocks are clamped on the two sides of the extension plate when they are closed.

[0008] When the rotating shaft rotates, the I-shaped rings are driven to rotate synchronously through the cooperation between the limiting block and the limiting groove of the I-shaped ring, and the driving gear in the gear box is further driven to rotate; the driving gear drives the two driven gears on the upper and lower sides to rotate in opposite directions through meshing transmission, so that the lifting screws fixed to the driven gears rotate synchronously; the rotation motion is converted into the vertical lifting of the lifting block through the threaded cooperation between the lifting screw and the lifting block, and finally the V-shaped blocks drive the extension plates at the two ends of the fixed arc-shaped plate and the moving arc-shaped plate to be clamped up and down.

[0009] The active lead screw provides the basic clamping force, and the V-block limits the extension plate through the V-groove, directly restricting the reverse rotation tendency of the active lead screw caused by vibration. The anti-loosening effect is far superior to the traditional single clamping structure. The sliding fit between the I-ring and the rotating shaft can adjust the position of the gearbox according to the distance between the extension plates, adapting to the limit requirements under different clamping conditions. The interior of the anti-theft box is divided into a meter compartment and an operating compartment by a partition. The top and bottom of the meter compartment are equipped with wire channels. The partition physically separates the interior of the anti-theft box. The meter compartment independently houses the agricultural irrigation meter and wiring terminals, while the operating compartment has a separate transmission anti-loosening component. The wire channels serve as cable entry and exit channels, ensuring a neat connection between the meter wiring and the cables of the external irrigation and drainage equipment.

[0010] The inner wall of the operating cabin is rotatably connected to a lead screw gear and a rotating shaft gear. The lead screw gear and the rotating shaft gear mesh with each other. The lead screw gear is fixedly connected to the lead screw, and the rotating shaft gear is fixedly connected to the rotating shaft.

[0011] The drive screw gear and the rotating shaft gear form a linkage transmission through tooth surface meshing. When the drive screw gear is rotated, it both drives the drive screw to rotate to clamp the arc plate and synchronously drives the rotating shaft gear to rotate, thereby driving the rotating shaft and the subsequent V-block limiting structure. There is no need to separately adjust the clamping and anti-loosening structures; rotating the drive screw gear can simultaneously complete the clamping of the arc plate and the limiting of the V-block, greatly simplifying the field installation process. The gear transmission can reduce the operating torque by adjusting the gear ratio, making it convenient for operators to rotate manually.

[0012] The inner wall and partition of the operating cabin are provided with multiple sliding grooves at corresponding positions. A rack is slidably connected in the sliding groove. When the rack abuts against the inner wall of the operating cabin where the drive screw gear and the rotating shaft gear are located, the rack meshes with the drive screw gear.

[0013] The rack can slide horizontally along the sliding groove. When it slides to the inner wall of the operating compartment, the teeth of the rack mesh with the teeth of the drive screw gear, restricting the rotational freedom of the drive screw gear through the tooth engagement. When adjustment is needed, the rack can be unlocked by sliding it in the opposite direction to disengage. Replacing traditional pin tumbler locks that are easily pried open, the rack and gear engagement has high locking strength. Criminals cannot easily rotate the drive screw through external components. They can only open the anti-theft box to disengage the rack and drive screw gear and rotate the drive screw from the inside to disassemble the device, preventing the meter box from being dismantled and stolen. Even if the V-block anti-loosening structure fails, the rack can still prevent the drive screw from reversing by locking the drive screw gear, further improving the reliability of the anti-loosening mechanism.

[0014] Multiple rubber pads are fixedly connected to the inner walls of the fixed arc-shaped plate and the moving arc-shaped plate. Utilizing the elastic deformation properties of rubber, the rubber pads create a flexible contact between the arc-shaped plate and the surface of the utility pole, filling in the minute unevenness of the pole's surface and simultaneously increasing the static friction between the rubber and the pole.

[0015] The V-shaped block has a groove through which the drive screw passes. The size of the groove is adapted to the outer diameter of the drive screw. When the V-shaped block is clamped and limited, the drive screw is embedded in the groove, avoiding structural interference between the V-shaped block and the drive screw.

[0016] A rotating handle is fixedly connected to the drive screw gear. The rotating handle is rigidly connected to the drive screw gear through a fixed structure, which increases the operating torque and makes rotating the drive screw gear easier.

[0017] A push-pull handle is fixedly connected between the racks in the same operating compartment. The push-pull handle connects and fixes multiple racks in the same operating compartment in series. The operator can push and pull the handle to drive all racks to move along the sliding groove simultaneously, so that multiple racks can simultaneously engage or disengage from the driving screw gear.

[0018] Working principle: The operator rotates the drive screw gear by turning the handle on the drive screw gear inside the control cabin. Because the drive screw gear meshes with the shaft gear, they move synchronously. The drive screw gear directly drives the drive screw fixed to it, while the shaft gear drives the shaft to rotate as well. When the drive screw rotates, the threaded engagement with the protruding plates at both ends of the moving arc plate converts the rotational motion into linear motion, pushing the moving arc plate along the drive screw axis towards the fixed arc plate. This, in conjunction with the fixed arc plate, clamps the utility pole. The rubber pads on the inner wall of the fixed arc plate elastically deform to fill the tiny unevenness on the surface of the utility pole, increasing static friction and improving clamping stability, adapting to utility poles of different diameters. The protruding plates at both ends of the fixed arc plate only serve as rotational supports for the drive screw, maintaining the stability of the fixed end. During the rotation of the shaft, the limiting block on its outer wall cooperates with the limiting groove on the inner wall of the I-shaped ring, driving the I-shaped ring to rotate synchronously, which in turn drives the active gear in the gearbox to rotate. The active gear drives the driven gears on the upper and lower sides to rotate in the opposite direction through meshing transmission, causing the lifting screw fixedly connected to the driven gear to rotate synchronously. The threaded engagement between the lifting screw and the lifting block converts the rotational motion into the vertical lifting of the lifting block, ultimately driving the V-shaped block to move up and down. The V-shaped groove clamps and limits the extension plates of the fixed arc plate and the moving arc plate, directly restricting the reverse rotation tendency of the active screw caused by vibration, achieving an anti-loosening effect. In addition, the groove on the V-shaped block can accommodate the active screw, avoiding structural interference between the two. Meanwhile, the anti-theft box is divided into an independent meter compartment and an operating compartment by a partition. The meter compartment is used to house the agricultural drainage meter and wiring terminals. The wire troughs at the top and bottom provide a neat channel for the cables to enter and exit, ensuring orderly wiring. The rack in the operating compartment can slide horizontally along the sliding groove by pushing and pulling the handle. When the rack abuts against the inner wall of the operating compartment, its teeth mesh with the drive screw gear, restricting the rotation of the drive screw gear through the meshing of the teeth. When the device needs to be adjusted or disassembled, the rack can be unlocked by pulling the push and pull handle in the opposite direction to disengage the rack. This ensures that the agricultural drainage meter box is stably installed in the field environment and is not easily stolen.

[0019] The present invention has the following beneficial effects: The active lead screw drives the moving arc plate to cooperate with the fixed arc plate to achieve a circumferential clamping of the utility pole. The rubber pad fills the uneven surface of the utility pole through elastic deformation and increases static friction. Combined with the limiting effect of the V-block on the protruding plate, it effectively prevents the lead screw from reversing due to vibration or environmental stress, ensuring the long-term stability of the fixing device. It avoids the defects of easy loosening of traditional wire binding methods and significantly improves the installation reliability of agricultural drainage meter boxes in complex field environments.

[0020] The operating compartment is equipped with a rack and pinion locking mechanism that engages with the drive screw. When the rack slides into engagement with the gear, it prevents the drive screw from being rotated arbitrarily. The lock can only be released by opening the anti-theft box, thus effectively preventing the meter box from being illegally dismantled, improving the security performance of the field meter box, and reducing the risk of theft of the meter and power facilities.

[0021] The device adopts an adjustable arc plate design, which can adapt to the different diameters of utility poles by rotating the active screw. At the same time, the sliding fit between the I-shaped ring and the rotating shaft allows the V-block to adjust its position according to the clamping state, so that the device can be widely used on utility poles of various specifications, improving the versatility and applicability of the equipment and meeting the diverse installation needs in the field.

[0030] The present invention will be further described in detail below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] An integrated anti-theft and anti-loosening function mounting device for agricultural drainage meter boxes includes an anti-theft box 1. A fixed arc plate 6 is fixedly connected to one side of the anti-theft box 1. A movable arc plate 7 is provided on the side of the fixed arc plate 6 away from the anti-theft box 1. Both ends of the fixed arc plate 6 and the movable arc plate 7 are fixedly connected to protruding plates 9. A drive screw 10 is rotatably connected to both sides of the fixed arc plate 6 on the anti-theft box 1. The drive screw 10 is rotatably connected to the protruding plates 9 at both ends of the fixed arc plate 6 and passes through the protruding plates 9 at both ends of the fixed arc plate 6. The drive screw 10 is threadedly connected to the protruding plates 9 at both ends of the movable arc plate 7.

[0032] By rotating the drive screw 10, and utilizing its threaded engagement with the extension plate 9 of the moving arc plate 7, the rotational motion is converted into linear motion. This drives the moving arc plate 7 to move closer to or further away from the fixed arc plate 6 along the axial direction of the drive screw 10, thereby achieving a circumferential clamping of utility poles of different diameters. This structure replaces the traditional wire binding, providing a continuous and stable clamping force through mechanical threads, fundamentally solving the loosening problem caused by vibration or material fatigue. It also boasts wide adaptability and strong versatility.

[0033] A rotating shaft 15 is rotatably connected to the outside of two active lead screws 10 on the anti-theft box 1. A limit block 16 is fixedly connected to the outer wall of the rotating shaft 15. Two I-shaped rings 18 are slidably connected on the rotating shaft 15. A limit groove 27 that cooperates with the limit block 16 is opened on the inner wall of the I-shaped ring 18. A gearbox 17 is rotatably connected in the I-shaped groove on the outer wall of the two I-shaped rings 18. An active gear 19 is installed on one of the I-shaped rings 18. A driven gear 20 meshes on the upper and lower sides of the active gear 19. A lifting lead screw 14 is fixedly connected to the side of each driven gear 20 away from the active gear 19. The lifting lead screw 14 is rotatably connected to the gearbox 17 and passes through the gearbox 17. A lifting block 12 is threadedly connected to the outer wall of the lifting lead screw 14. A V-shaped block 11 is fixedly connected to the side of the lifting block 12 near the protruding plate 9. When the V-shaped block 11 is engaged, it is locked onto both sides of the protruding plate 9.

[0034] When the rotating shaft 15 rotates, the limiting block 16 and the limiting groove 27 drive the I-shaped ring 18 to rotate. This, in turn, through the meshing of the driving gear 19 and the driven gear 20, causes the upper and lower lifting screws 14 to rotate synchronously in opposite directions. Ultimately, this drives the V-block 11 to move up and down and clamp the protruding plate 9. This design automatically locks the core transmission component of the clamping mechanism after clamping, effectively resisting the reverse rotation tendency of the driving screw 10 caused by external vibrations, achieving secondary anti-loosening, and greatly improving the long-term stability of the device.

[0035] The interior of the anti-theft box 1 is divided into a meter compartment 3 and an operating compartment 4 by a partition 2. The top and bottom of the meter compartment 3 are provided with wire grooves 5. The inner wall of the operating compartment 4 is rotatably connected to a drive screw gear 21 and a rotating shaft gear 22. The drive screw gear 21 and the rotating shaft gear 22 mesh with each other. The drive screw gear 21 is fixedly connected to the drive screw 10, and the rotating shaft gear 22 is fixedly connected to the rotating shaft 15.

[0036] The clamping and anti-loosening functions are linked by the meshing of the drive screw gear 21 and the rotating shaft gear 22. The operator only needs to rotate the drive screw gear 21 to simultaneously drive the drive screw 10 to clamp and drive the rotating shaft 15 to activate the anti-loosening limit mechanism, which simplifies the field installation and debugging process and improves the ease of operation.

[0037] Multiple sliding grooves 25 are provided on the inner wall of the operating cabin 4 and at corresponding positions of the partition 2. A rack 24 is slidably connected in the sliding groove 25. When the rack 24 abuts against the inner wall of the operating cabin 4 where the drive screw gear 21 and the rotating shaft gear 22 are located, the rack 24 meshes with the drive screw gear 21.

[0038] The rack 24 constitutes the core anti-theft locking mechanism. When the rack 24 slides to engage with the drive screw 21, the mechanical interference between the teeth completely locks the rotation of the drive screw 21, thus preventing external disassembly. Criminals cannot turn the screw with conventional tools; they must open the anti-theft box to unlock it, greatly enhancing the device's anti-theft performance.

[0039] Multiple rubber pads 8 are fixedly connected to the inner walls of the fixed arc plate 6 and the moving arc plate 7. The rubber pads 8 utilize their high coefficient of friction and elastic deformation characteristics to increase the static friction with the surface of the utility pole, preventing the device from slipping; on the other hand, they fill the unevenness of the surface of the utility pole, making the clamping surface more fully contacted and the pressure distribution more uniform, further enhancing the reliability and stability of the clamping.

[0040] The V-block 11 has a groove 13 through which the drive screw 10 passes. The groove 13 provides clearance for the drive screw 10, ensuring that the V-block 11 will not structurally interfere with the drive screw 10 when it moves up and down to limit the extension plate 9, thus ensuring the smoothness and reliability of the anti-loosening mechanism.

[0041] A rotating handle 23 is fixedly connected to the drive screw gear 21. Push-pull handles 26 are fixedly connected between the racks 24 in the same operating compartment 4. The push-pull handles 26 connect multiple racks 24 into one unit, enabling synchronous control of all locking racks. The operator can simultaneously engage or disengage all racks and gears with a single push-pull action, simplifying locking and unlocking procedures and improving operational efficiency.

[0042] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
