Description

Technical Field

[0001] This utility model relates to the field of engineering machinery safety technology, specifically a system for preventing injury to personnel during loader operation in a greenhouse. Background Technology

[0002] In modern agricultural greenhouses and other facility agriculture, loaders are widely used for material transfer, soil leveling and other operations. However, the interior environment of greenhouses is characterized by small space, narrow passages, many pillars blocking the view and poor visibility. At the same time, multiple workers often work together in the work area. This complex environment creates blind spots for loaders when turning or reversing, which can easily lead to serious safety accidents involving collisions with workers.

[0003] Traditional anti-collision measures for construction machinery mainly rely on reversing radar, reversing camera and driver's visual observation. However, the monitoring range of reversing radar and camera is limited and cannot effectively identify dynamically moving personnel. Relying solely on the driver's vigilance will inevitably lead to negligence during long-term repetitive operations. Therefore, a loader operation in greenhouse anti-injury system is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a system for preventing injury to workers operating loaders in greenhouses, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a loader operation anti-injury system in a greenhouse, comprising a loader body and a camera, wherein a frame is fixedly connected to the bottom side of the loader body, and an adjustment mechanism and a multi-functional component are provided on the surface of the frame, and the adjustment mechanism is used to adjust the shooting angle of the camera;

[0006] The adjustment mechanism includes a rotating frame, a collar, a first connecting rod, and a second connecting rod. The camera is located inside the collar. The rotating frame, collar, and first connecting rod cooperate to drive the collar to rotate at multiple angles.

[0007] The multifunctional component includes a ring frame, an alarm, and multiple laser lights. The laser lights are used to provide sufficient illumination for the camera in dim environments, and the alarm sound is used to alert people.

[0008] Preferably, the ring frame is fixedly connected to the bottom side of the vehicle frame, and the plurality of laser lights are arranged in a circumferential distribution on the surface of the ring frame.

[0009] Preferably, the alarm is located on the outside of the loader body, and both the alarm and the laser light are electrically connected to the controller of the loader body.

[0010] Preferably, the adjustment mechanism further includes a first motor and a second motor;

[0011] The first motor is fixedly installed on one side of the vehicle frame, and the second motor is fixedly installed on the other side of the vehicle frame.

[0012] Preferably, the rotating frame is fixedly connected to the end of the output shaft of the first motor, and the collar is rotatably connected to the inner side of the rotating frame.

[0013] Preferably, one end of the first connecting rod is rotatably connected to the protrusion of the collar, and one end of the second connecting rod is fixedly connected to the end of the output shaft of the second motor.

[0014] Preferably, the other ends of the first link and the second link are hinged by a connecting shaft, and the first link and the second link are staggered.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The adjustment mechanism controls the first motor to turn the rotating frame and camera to the horizontal position of the person, and at the same time controls the second motor to adjust the pitch angle of the camera through the first and second linkages, ensuring that the person is always in the center position of the camera image, realizing dynamic tracking. Thus, the camera gains the ability to move in two degrees of freedom, horizontal and pitch, and can not only look around, but also look up (to observe higher or distant targets) and look down (to observe nearby, blind spots under the vehicle or targets on the ground), forming a spherical monitoring range, effectively avoiding the field of view limitation of fixed-installation reversing cameras;

[0016] The laser light and alarm allow the high-intensity beam emitted by the laser light to directly illuminate the dimly lit areas around the loader, providing ample and uniform light for the camera. This ensures that the camera captures clear images with low noise, allowing the image recognition algorithm (or driver observation) to accurately identify personnel. The alarm sound warns personnel to move away quickly and reminds the driver to stop operating immediately. This structure creates a dynamic safety protection zone covering the area around the loader, especially blind spots, thus compensating for the shortcomings of traditional reversing radar and cameras, and effectively warning against and preventing collisions with moving personnel.

[0022] 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.

[0023] Please see Figures 1-4 This utility model provides a technical solution for a loader operation safety system in a greenhouse: a loader operation safety system in a greenhouse includes a loader body 1 and a camera 3. A frame 2 is fixedly connected to the bottom side of the loader body 1. An adjustment mechanism 5 and a multi-functional component are provided on the surface of the frame 2. The adjustment mechanism 5 is used to adjust the shooting angle of the camera 3.

[0024] The adjustment mechanism 5 includes a rotating frame 503, a collar 504, a first connecting rod 505 and a second connecting rod 506. The camera 3 is located inside the collar 504. The rotating frame 503, the collar 504 and the first connecting rod 505 cooperate to drive the collar 504 to rotate at multiple angles.

[0025] The multifunctional component includes a ring frame 6, an alarm 4, and multiple laser lights 7. The laser lights 7 are used to provide sufficient illumination for the camera 3 in dim environments, and the alarm sound of the alarm 4 is used to alert people.

[0026] Please refer to this carefully. Figure 3 The ring frame 6 is fixedly connected to the bottom side of the frame 2, and multiple laser lights 7 are arranged in a circular pattern on the surface of the ring frame 6.

[0027] In this embodiment, the high-intensity beam emitted by the laser lamp 7 can directly illuminate the dark area around the loader body 1, providing sufficient and uniform light source for the camera 3, ensuring that the captured image is clear and has low noise.

[0028] Please refer to this carefully. Figure 2 The alarm 4 is located on the outside of the loader body 1, and both the alarm 4 and the laser light 7 are electrically connected to the controller of the loader body 1.

[0029] In this embodiment: when the camera 3 determines through image recognition technology that a person has entered the preset danger area or that a person is in a dynamic approaching state, the controller will immediately trigger the alarm 4 to sound an alarm. This warns the person to move away quickly and also reminds the driver to stop operating immediately.

[0030] Please refer to this carefully. Figure 4 The adjustment mechanism 5 also includes a first motor 501 and a second motor 502;

[0031] The first motor 501 is fixedly installed on one side of the frame 2, and the second motor 502 is fixedly installed on the other side of the frame 2.

[0032] In this embodiment: by controlling the first motor 501, the rotating frame 503 and the camera 3 are precisely turned to the horizontal position of the person. At the same time, the second motor 502 is controlled to adjust the pitch angle of the camera 3 through the first link 505 and the second link 506, so as to ensure that the person is always in the center position of the camera 3's image and realize dynamic tracking.

[0033] Please refer to this carefully. Figure 4 The rotating frame 503 is fixedly connected to the end of the output shaft of the first motor 501, and the collar 504 is rotatably connected to the inner side of the rotating frame 503.

[0034] In this embodiment: the output shaft of the first motor 501 drives the rotating frame 503 and the collar 504 to rotate, and the camera 3 follows the rotating frame 503 and the collar 504 to perform a horizontal circular motion.

[0035] Please refer to this carefully. Figure 4 One end of the first connecting rod 505 is rotatably connected to the protrusion of the collar 504, and one end of the second connecting rod 506 is fixedly connected to the end of the output shaft of the second motor 502.

[0036] In this embodiment: the output shaft of the second motor 502 drives the second connecting rod 506 to rotate, which will push or pull the first connecting rod 505 through the hinge point.

[0037] Please refer to this carefully. Figure 4 The other ends of the first link 505 and the second link 506 are hinged by a connecting shaft, and the first link 505 and the second link 506 are staggered.

[0038] In this embodiment: Since the first connecting rod 505 and the second connecting rod 506 are hinged through a connecting shaft to form a structure similar to a crank rocker, the movement of the first connecting rod 505 will force the collar 504 to take its connection point with the rotating frame 503 as the axis.

[0039] Working principle: When the first motor 501 is working, the output shaft of the first motor 501 drives the rotating frame 503 and the collar 504 to rotate. The camera 3 then follows the rotating frame 503 and the collar 504 to perform a horizontal circular motion. When the loader body 1 starts or is working, the controller can command the first motor 501 to perform periodic or specific angle reciprocating rotation, so that the camera 3 can perform a wide-angle scan of the environment around the loader body 1, establish a panoramic view, and initially identify personnel in the work area. Then, by starting the second motor 502, the output shaft of the second motor 502 drives the second connecting rod 506 to rotate. This will push or pull the first connecting rod 505 through the hinge point. Since the first connecting rod 505 and the second connecting rod 506 are hinged through the connecting shaft, forming a structure similar to a crank rocker, the movement of the first connecting rod 505 will force the collar 504 to swing up and down (i.e., pitch) with its connection point with the rotating frame 503 as the axis.

[0040] By fixing multiple laser lights 7 in a circular arrangement on the ring frame 6 on the bottom side of the frame 2, the high-intensity beams emitted by the laser lights 7 can directly illuminate the dark areas around the loader body 1, providing sufficient and uniform light source for the camera 3, ensuring that the captured image is clear and has low noise. This ensures that the image recognition algorithm (or driver observation) can accurately identify personnel regardless of changes in ambient light. When the camera 3 determines that a person has entered the preset danger area or is in a dynamic approach state through image recognition technology (which is existing technology and can be integrated into the controller), the controller will immediately trigger the alarm 4 to sound an alarm. This warns the personnel to move away quickly and also reminds the driver to stop operating immediately.

[0041] It should be noted that a personnel positioning system is installed on the loader body 1. When the distance between the personnel and the loader body 1 is less than or equal to 5 meters, the positioning system will automatically alarm, and the automatic braking system built into the loader body 1 will apply the brakes. The braking principle of the automatic braking system and the loader body 1 is hydraulic braking. The piston in the master cylinder will receive the pedal thrust, and the brake fluid will be transmitted to the pistons of each brake caliper through the pipeline. Then, it will push the brake shoes outward, so that the brake pads will rub against the inner surface of the brake drum. In addition, this patented system adds oil to the oil inlet of the master cylinder and connects to the solenoid valve. An oil pipe is added to the outlet of the solenoid valve and connects to the outlet of the master cylinder. When the positioning system alarms, the solenoid valve will operate and the brakes will be applied. When the positioning system alarm is cleared, the brakes will be applied again.

[0042] 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.
