Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of monitoring camera equipment, in particular to a crop growth monitoring intelligent monitoring device. BACKGROUND

[0002] With the rapid development of smart agriculture, various high-tech products have entered the field of agriculture with their respective advantages. For example, a hanging rail type intelligent inspection monitoring device applied to greenhouse crops mainly includes a track suspended in the air, a trolley walking along the track, and a monitoring camera suspended under the trolley. This kind of monitoring device not only can improve the coverage of monitoring and reduce the dead angle of monitoring, but also will not affect the ground operation because it is installed in the air. Some inspection monitoring devices are also integrated with various advanced monitoring instruments such as infrared thermal imagers, visible light high-definition cameras, auxiliary lighting sources, temperature and humidity sensors, and illumination sensors, etc. Real-time acquisition of multi-dimensional data such as spatial images, spectral characteristics, and radiation characteristics of the planted crops in the greenhouse, through the collection and arrangement of a large number of sample data, modeling analysis, the growth data of the crops such as nutrient composition, apparent information, water content, and maturity can be obtained, and the comprehensive monitoring of the growth of greenhouse crops and the ground environment in time and space dimensions can be realized.

[0003] However, in some greenhouses, in order to ensure the normal growth of crops, a certain humidity needs to be maintained in the greenhouse. When the monitoring camera is working, it will generate a certain amount of heat, resulting in a certain temperature difference between the inside and outside of the camera. In this case, water mist is easily formed on the outer surface of the lens, which undoubtedly affects the quality of monitoring imaging. Moreover, the heat generated by the camera and the emitted infrared light can easily attract mosquitoes in the greenhouse, causing mosquitoes to fly and gather in front of the lens. Over time, insect glue and insect eggs and other impurities can be produced on the surface of the lens, which will also affect the monitoring effect. In addition, the camera is installed at a high place, so this will bring a lot of trouble to the later maintenance and cleaning work. SUMMARY

Moreover, the two walking wheels 303 located on the two sides are also transmissionally connected through the third belt transmission assembly 304, specifically, the two third transmission wheels 3041 are respectively coaxially fixed with the two walking wheels 303, and the third transmission belt 3042 is transmissionally installed on the two third transmission wheels 3041. Therefore, when the transmission device 6 drives the second transmission shaft 302 to rotate, the second transmission shaft 302 can drive the two walking wheels 303 adjacent to it to rotate synchronously through the third belt transmission assembly 304, and the two walking wheels 303 can drive the two walking wheels 303 on the outermost side to rotate through the third belt transmission assembly 304, so as to drive all the walking wheels 303 to rotate synchronously.

Since the heat dissipation fins 101 increase the heat dissipation area, the heat dissipation effect can be improved to a certain extent, and the airflow blown out through the air outlet hole 902 can also blow on the heat dissipation fins 101, so that the heat dissipation capacity of the heat dissipation fins 101 can be further improved, the heat dissipation performance of the monitoring camera 1 is further improved, the temperature difference between the inside and outside of the monitoring camera 1 is prevented from being too large, and the occurrence of lens fogging can be further reduced.

[0046] With reference to Figure 1 With reference to 4 The trolley 2 is provided with a mosquito catching device 11. The mosquito catching device 11 comprises two negative pressure suction pipes 1101. One end of each of the two negative pressure suction pipes 1101 is connected with the air inlet of one of the two centrifugal fans 7, and the other end of each of the two negative pressure suction pipes 1101 extends out of the trolley 2.

The triggered static pressure switch 12 can control the trapping lamp 1107 outside the centrifugal fan 7 to open and attract mosquitoes, which can further prevent mosquitoes from gathering around the lens of the monitoring camera 1.

[0049] Referring to Figure 1 , Figure 2 , Figure 9 and Figure 10 , the crop growth monitoring intelligent monitoring device further comprises a lifting device 4 connected between the lower surface of the trolley 2 and the monitoring camera 1, the lifting device 4 comprising a scissor-type telescopic frame 401, a multi-stage telescopic cover 402, and an electric telescopic rod 403 fixedly connected to the lower surface of the trolley 2, the scissor-type telescopic frame 401 comprising four groups of scissor arm units 4010, the four groups of scissor arm units 4010 being hingedly connected end to end along the height direction, and each group of scissor arm units 4010 comprising a first scissor arm 4011 and a second scissor arm 4012 arranged in cross, the first scissor arm 4011 and the second scissor arm 4012 being rotatably connected with a pin shaft 4013 at the cross hinge joint, the multi-stage telescopic cover 402 comprising four cover bodies successively sleeved, the uppermost cover body being fixedly installed on the lower surface of the trolley 2, the monitoring camera 1 being fixedly installed on the lower surface of the lowermost cover body, and the four pin shafts 4013 being connected with the adjacent cover bodies from top to bottom, and the telescopic end of the electric telescopic rod 403 being connected with the second cover body from the top through a connecting rod 404.

[0050] Referring to Figure 2 and Figure 9The air supply assembly 10 comprises two air inlet pipes 1001, a multi-stage telescopic pipe 1002 and an air outlet hose 1003, the multi-stage telescopic pipe 1002 comprises four pipe bodies which are sequentially sleeved, and connecting frames 1004 are fixedly connected between the four pipe bodies and four cover bodies, respectively, upper ends of the two air inlet pipes 1001 are connected with air outlets of the two centrifugal fans 7, respectively, lower ends of the two air inlet pipes 1001 are communicated with the uppermost pipe body, and the lowermost pipe body is communicated with the air outlet cover 9 through the air outlet hose 1003, since the air outlet hose 1003 is a soft pipe, the air outlet hose 1003 will not affect the lens angle adjustment of the monitoring camera 1.

[0051] Moreover, the upper part of the air inlet pipe 1001 is vertical, a connecting pipe 13 of the static pressure switch 12 is communicated with the upper part of the air inlet pipe 1001, and specifically, one end of the connecting pipe 13 close to the air inlet pipe 1001 is perpendicular to the air inlet pipe 1001, so as to facilitate the static pressure detection of the air flow blown out by the centrifugal fan 7 and passing through the connecting pipe 13.

[0052] In the application, the track 15 is arranged in the agricultural greenhouse, and the monitoring camera 1 suspendedly installed below the track 15 can monitor the growth of crops in the greenhouse. When it is necessary to perform inspection, the two motors 14 are started, the output ends of the two motors 14 can drive the first large gear 503 to rotate through the two first small gears 502, the first large gear 503 drives the second large gear 505 to rotate through the second small gear 504, and the purpose of deceleration is achieved. Then the second large gear 505 drives the lower first transmission wheel 6031 to rotate slowly through the electromagnetic clutch 601, the rotation of the lower first transmission wheel 6031 drives the first transmission shaft 602 to rotate synchronously through the first transmission belt 6032 and the upper first transmission wheel 6031, the first transmission shaft 602 drives the second transmission shaft 302 to rotate synchronously through the second transmission wheel 6041 and the second transmission belt 6042, and the second transmission shaft 302 drives the walking wheel 303 to rotate through the third transmission wheel 3041 and the third transmission belt 3042, so as to drive the trolley 2 and the monitoring camera 1 to walk along the track 15, thereby achieving the purpose of inspecting the crops in the greenhouse.

[0053] And in the process of inspection, the output end of the two motors 14 rotates synchronously, and the transmission direction of the two one-way clutches 801 is also opposite, so one of the motors 14 can drive the first transmission gear 803 outside it to rotate through the one-way clutch 801, and the first transmission gear 803 drives the drive shaft 802 to rotate through the second transmission gear 804, and the drive shaft 802 ultimately drives the centrifugal fan 7 connected to it to operate, thereby conveying airflow in the air outlet cover 9 through the air inlet pipe 1001, the multi-stage telescopic pipe 1002 and the air outlet hose 1003, and the flowing airflow is ultimately blown to the outside of the lens of the monitoring camera 1 and the heat dissipation fin 101 through the air blowing groove 901 and the air outlet hole 902, thereby defogging and dissipating heat for the monitoring camera 1. Although the other motor 14 also rotates, the one-way clutch 801 at the output end of the motor does not transmit power in this direction, so it does not drive the centrifugal fan 7 connected to it to operate. Only when the trolley 2 moves in the opposite direction, the output ends of the two motors 14 rotate synchronously in the opposite direction, the previously transmitting one-way clutch 801 does not transmit power in this direction, so the previously operating centrifugal fan 7 stops operating, and the previously non-transmitting one-way clutch 801 starts transmitting power and drives the previously non-operating centrifugal fan 7 to operate, thereby enabling the trolley 2 to blow air through one of the centrifugal fans 7 regardless of whether it is moving forward or backward, and defogging and dissipating heat. The operation switching between the two centrifugal fans 7 is automatic and does not require additional intervention.

[0054] The operation of the centrifugal fan 7 conveys the blown airflow to the air inlet pipe 1001 connected to it and generates a certain static pressure. At this time, the static pressure switch 12 connected to the air inlet pipe 1001 detects the static pressure and triggers and conducts the circuit to control the trap lamp 1107 outside the centrifugal fan 7 to turn on. The operation of the centrifugal fan 7 also draws air through the negative pressure suction pipe 1101 and the negative pressure suction head 1103 connected to the air inlet of the centrifugal fan 7. Since mosquitoes have the characteristic of phototaxis, mosquitoes can be attracted to the negative pressure suction head 1103, and then sucked into the negative pressure suction head 1103 under the negative pressure suction of the centrifugal fan 7 and blocked by the filter screen 1102 to prevent entering the centrifugal fan 7. Since the filter screen 1102 is gradually inclined downward, mosquitoes will slide into the collection box 1105 through the through hole 1104 and be stuck on the mosquito sticking plate 1106 for collection, ultimately achieving the purpose of auxiliary insect catching and effectively preventing mosquitoes from gathering in front of the lens of the monitoring camera 1.

[0055] And only when the centrifugal fan 7 is running, the side of the trap lamp 1107 will be turned on by the static pressure switch 12, when the centrifugal fan 7 stops running, the static pressure switch 12 will be disconnected because the static pressure disappears, so that the trap lamp 1107 is automatically turned off, if the walking direction of the trolley 2 is changed at this time and the other centrifugal fan 7 is running, the other trap lamp 1107 will be turned on by the other static pressure switch 12, at this time the insect catching work will also be carried out, so as to realize the purpose of automatic switching of the trap lamp 1107 and the insect catching work, avoiding the two trap lamps 1107 being turned on at the same time, and playing a positive role in saving electric energy.

[0056] When the device only needs to defog and does not need to walk and patrol, the electromagnetic clutch 601 can be disconnected, at this time the transmission between the speed reducer 5 and the transmission device 6 can be disconnected, so that the rotation of the motor 14 only drives the centrifugal fan 7 to run, and the walking device 3 does not walk.

[0057] When the telescopic end of the electric telescopic rod 403 is extended downward, it will also push the upper second cover body in the multi-stage telescopic cover 402 downward through the connecting rod 404 to extend and slide downward, at this time the cover body will drive the pin shaft 4013 to move downward synchronously, and drive the first shear arm 4011 and the second shear arm 4012 to rotate around the pin shaft 4013, so as to slowly unfold the shear telescopic frame 401, at this time the shear telescopic frame 401 drives the lower two cover bodies to extend and slide downward through the lower two pin shafts 4013, and controls the monitoring camera 1 to descend, and the same reason, when the telescopic end of the electric telescopic rod 403 is retracted upward, it will also pull the monitoring camera 1 upward through the shear telescopic frame 401 and the multi-stage telescopic cover 402, so as to realize the purpose of adjusting the height of the monitoring camera 1, so that the monitoring range is wider, and the multi-stage telescopic cover 402 is sleeved on the shear telescopic frame 401 and the electric telescopic rod 403, so as to protect the related parts to a certain extent, prevent impurities such as mosquitoes, water vapor and the like from entering the inside, and thus ensure the service life of the related parts.

[0058] When the lifting device 4 is telescopic lifting, the lower three cover bodies in the multi-stage telescopic cover 402 will also drive the lower three pipe bodies in the multi-stage telescopic pipe 1002 to be telescopic synchronously through the connecting frame 1004, and thus the length of the multi-stage telescopic pipe 1002 is adjusted, so that even if the height of the monitoring camera 1 is adjusted, it will not affect the air supply work, and the normal defogging and heat dissipation work is ensured.
