Description

Technical Field

[0001] The present disclosure relates to the technical field of storage yard safety monitoring and automatic control, and in particular to a temperature detection spray system. Background Art

[0002] Dangerous goods container yards are stacked in the open air. In the yard, inspectors usually identify abnormal temperatures on the surface of the containers as a source of danger. Climate change and seasonal changes will affect the temperature of the container surface. For example, high temperatures and direct sunlight will increase the temperature of the container surface. The stacking density of containers will also affect the temperature of the containers. Dense stacking can easily cause poor air circulation, leading to local temperature increases. The operation of mechanical equipment in the yard may also affect the temperature of the container area. For example, operations such as container cranes and transport vehicles will generate heat, affecting the temperature of the surrounding area.

[0003] At present, fixed spraying equipment is installed around the storage yard. When the temperature of the storage yard is detected to be abnormal, the spraying equipment starts and keeps spraying water to the storage yard. The spraying equipment sprays water to the storage yard over a large area and cannot focus on the area with abnormal temperature, resulting in a waste of water resources.

[0004] Therefore, how to provide a temperature detection spraying system that can link spraying equipment to centrally spray abnormal temperature areas and thus save water resources is an urgent problem that needs to be solved. Utility Model Content

[0027] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.

[0028] A temperature detection and spraying system includes: a temperature detection device 2, configured to be set at a preset height in a detection area 1 to collect temperature signals of the detection area 1 in real time; a control component 3, connected to the temperature detection device 2, at least for receiving and processing the temperature signals collected by the temperature detection device 2; a preset track 4; and at least one spraying device 5, movably connected to the preset track 4 and at least one spraying device 5 is in signal connection with the control component 3; wherein, the control component 3 is at least for controlling at least one spraying device 5 to move on the preset track 4.

[0029] Specifically, as Figure 1 - Figure 2 shown, the detection area 1 includes but is not limited to a dangerous goods yard. The number of temperature detection devices 2 can be set according to the actual area of the detection area 1 and the detection range of the temperature detection devices 2, such as 2, 3, or 5, etc. The temperature detection device 2 can specifically be an infrared thermal imaging camera, which is provided with a pan-tilt head, and the camera of the temperature detection device 2 rotates along a preset angle through the pan-tilt head to achieve real-time inspection of the detection area 1. The control component 3 can be a microcontroller, a PLC, etc., capable of comparing the temperature signals collected by the temperature detection device 2 with a preset temperature threshold, determining whether to activate the spraying system, and issuing corresponding control instructions. The preset track 4 is the basic framework for the movement of the spraying device 5. The preset track 4 can be straight, curved, or a combination of straight and curved tracks. For example: the preset track 4 can be two straight tracks oppositely arranged on both sides of the yard, or a single straight track arranged on one side of the yard. The number of spraying devices 5 arranged on the preset track 4 can be 1, 3, or 10, etc. Here, the number of spraying devices 5 on the preset track 4 is not specifically limited. The control component 3 can transmit the position information of the temperature abnormal area to the drive motor that drives the spraying device 5 to move, and transmit the instructions to start spraying and stop spraying to the pump 53 that controls the spraying of the spraying device 5, so as to control the movement of the spraying device 5 on the preset track 4 and the opening or closing of the nozzle 52 of the spraying device 5.

[0030] A temperature detection and spraying system provided by the present disclosure includes a temperature detection device 2, a control component 3, a preset track 4, and at least one spraying device 5. The system uses the temperature detection device 2 to detect the temperature signal of the dangerous goods container area in the area to be detected in real time and sends the temperature signal to the control component 3. The control component 3 controls the movement of the spraying device 5 on the preset track 4 according to the received temperature signal, so that multiple spraying devices 5 move to the temperature abnormal area and start the spraying device 5 as needed to spray the area intensively to reduce the temperature of the temperature abnormal area. When the temperature detection device 2 detects that the temperature of the area has dropped to a safe range, the control component 3 controls the spraying device 5 to stop spraying. Therefore, the system has the advantages of being able to link the spraying equipment through the control component 3, adjusting the position of the spraying device 5 and controlling the start and stop of the spraying device 5, spraying the temperature abnormal area intensively, and saving water resources.

[0031] In some embodiments, the temperature detection and spraying system further includes: a circulation pool 6, which has an accommodation space for accommodating a spraying medium; each spraying device 5 includes: a support column 51, which is driven by a driving motor signal-connected to the control component 3 to slide on the preset track 4; a nozzle 52, which is arranged on the support column 51 and is used to spray the spraying medium into the area to be sprayed; a pump 53, which is used to transport the spraying medium to the nozzle 52; a spraying pipe 54, which connects the pump 53 and the nozzle 52 to provide a flow channel for the spraying medium; and a connecting pipe 55, whose input end is connected to the circulation pool 6 and whose output end is connected to the pump 53.

[0032] Specifically, as Figure 2 shown, there are no specific limitations on the size and specific position of the circulation pool 6 here. The circulation pool 6 is used to accommodate the spraying medium, and the spraying medium includes but is not limited to rainwater or purified water. Each spraying device 5 includes a support column 51, and the height of the support column 51 can be set according to the height of the dangerous goods containers in the yard. The support column 51 is driven by a driving motor to slide on the preset track 4 (the driving method here is a common driving method and will not be specifically described in the specification). The nozzle 52 is arranged on the support column 51, and the specific height of the nozzle 52 can be set according to the height of the dangerous goods containers in the yard. The number of nozzles 52 on each support column 51 can be any number, such as: 1, 2, or 3, etc. For example: multiple nozzles 52 are arranged on each support column 51. The multiple nozzles 52 can be arranged at the same height and have different spraying directions, or arranged at different heights and have the same spraying direction. One end of the spraying pipe 54 is connected to the output end of the pump 53 and the other end is connected to the nozzle 52, which is used to provide a flow channel for the spraying medium. One end of the connecting pipe 55 communicates with the circulation pool 6 and the other end is connected to the input end of the pump 53, which is used to provide a flow channel for the spraying medium.

[0033] In some embodiments, the temperature detection and spraying system further includes: a pressure regulating valve disposed on the spray pipe 54; a flow regulating valve disposed on the spray pipe 54; and a meteorological measuring device 7 connected to the input end of the control component 3, and the control component 3 is at least further configured to control the pressure regulating valve and the flow regulating valve.

[0034] Specifically, as Figure 1 shown, the system further includes a pressure regulating valve and a flow regulating valve (not shown in the figure), both of which are disposed on the spray pipe 54. The pressure regulating valve is in signal connection with the control component 3, and the flow regulating valve is in signal connection with the control component 3. The signal connection here can be specifically a wireless connection or a wired connection. The system further includes a gas phase measuring device, which is in signal connection with the control component 3. The signal connection here can be specifically a wireless connection or a wired connection. The gas phase measuring device can collect and record meteorological information such as wind speed, wind direction, and air pressure and can transmit this meteorological information to the control component 3. The control component 3 controls the pressure regulating valve according to the meteorological information to adjust the water pressure sprayed by the nozzle 52 and controls the flow regulating valve to adjust the water volume sprayed by the nozzle 52. For example, when the wind speed is too high and the wind direction is different from the direction of the water sprayed by the nozzle 52, the control component 3 can adjust the pressure regulating valve to increase the water pressure sprayed by the nozzle 52 to avoid the influence of the wind on the spraying and prevent the spraying direction from deviating from the temperature abnormal area. In addition, when the temperature of the area 1 to be detected is relatively high or the weather temperature is relatively high, the control component 3 can control the opening degree of the flow regulating valve to increase the water volume sprayed by the nozzle 52. By providing a pressure regulating valve, a flow regulating valve, and a gas phase measuring device in the system, the water flow pressure and water flow volume sprayed by the nozzle 52 can be adjusted according to meteorological information such as wind direction and ambient temperature, improving the spraying accuracy and spraying efficiency and reducing human intervention.

[0035] In some embodiments, the control component 3 includes: a data processing module 31 connected to the temperature detection device 2 through a network transmission component 8 to receive the temperature signal collected by the temperature detection device 2 and process the temperature signal; and a PLC controller 32, whose input port is connected to the data processing module 31, and is at least configured to receive the control signal sent after the data processing module 31 processes the temperature signal and control the spraying device 5 to act according to the control signal.

[0036] Specifically, as Figure 1As shown in the figure, the data processing module 31 can be connected to the temperature detection device 2 through the network transmission component 8. The network transmission component 8 may specifically include a switch 81, an optical fiber line, etc. The input port of the PLC controller 32 is signal-connected to the output port of the data processing module 31. Here, the signal connection may specifically be a wireless connection or a wired connection. The data processing module 31 can perform noise removal and image enhancement on the captured image, convert each pixel point of the captured image into its corresponding temperature value, and compare the temperature value with the temperature upper limit value set by the user. If the temperature exceeds the upper limit value, it is a temperature anomaly. Obtain the geographical location information of the temperature anomaly area, send a control signal to the PLC controller 32, and the PLC controller 32 controls the movement of the spraying device 5 to the temperature anomaly area according to the control signal and controls the spraying device 5 to spray. When the temperature in the temperature anomaly area drops below the temperature upper limit value, control the spraying device 5 to stop spraying water, and the spraying device 5 moves to the initial position. In addition, the PLC controller 32 can also be signal-connected to the temperature detection device 2 to receive the temperature signal sent by the temperature detection device 2 and issue a control instruction. The PLC controller 32 can feedback the information and results of the control instructions it issues to the data processing platform for storage, which is convenient for subsequent analysis and management.

[0037] In some embodiments, the network transmission component 8 includes: a switch 81, whose input port is connected to the temperature detection device 2, for receiving the temperature signal of the temperature detection device 2 and converting the temperature signal into a network protocol data packet; an optical fiber communication line 83, one end of which is connected to the output port of the switch 81 and the other end of which is connected to the control component 3, for transmitting the network protocol data packet between the switch 81 and the control component 3; a data parsing module 82, arranged on the optical fiber communication line 83, for establishing a data interface between the data processing module 31 and the temperature detection device 2 to realize data parsing and uploading.

[0038] Specifically, as Figure 1 shown, the input port of the switch 81 is connected to the output port of the temperature detection device 2, for receiving the temperature signal sent by the temperature detection device 2 and converting the temperature signal into a data packet format conforming to the network protocol. According to the preset routing rules, the encapsulated data packet is sent to the control component 3 through the optical fiber communication line 83, providing a physical channel suitable for long-distance transmission and not easily affected by electromagnetic interference for the transmission of the temperature signal. The data parsing module 82 is arranged in the optical fiber communication line 83, playing a bridging role, unpacking the data packet and restoring it to the original temperature signal for the data processing module 31 to process. The data parsing module 82 provides a unified data interface for the data processing module 31, enabling the data sent by different types of temperature detection devices 2 to be uniformly processed.

[0039] In some embodiments, the temperature detection and spraying system further includes: a temperature and humidity detector 9, connected to the data processing module 31, for monitoring the ambient temperature and ambient humidity; a temperature auxiliary measuring device 10, connected to the data processing module 31, for measuring the temperature of a fixed temperature reference source; the data processing module 31 further includes: an ambient temperature storage unit for storing historical ambient temperature information; a temperature calibration unit for calibrating the measurement accuracy of the temperature detection device 2 according to the ambient temperature and ambient humidity monitored by the temperature and humidity detector 9, the temperature of the fixed temperature reference source, and the historical ambient temperature information.

[0040] Specifically, as Figure 1As shown, the temperature detection and spraying system further includes a temperature and humidity detector 9, which is signal-connected to the data processing module 31. The temperature detection and spraying system further includes a temperature auxiliary measuring device 10, which is signal-connected to the data processing module 31. Here, the signal connection can specifically be a wireless connection or a wired connection. In order to avoid deviation in the measurement results caused by the low measurement accuracy of the temperature and humidity of the environment and the temperature detection device 2, the temperature value collected by the data processing module 31 is calibrated. This calibration process takes into account the influence of the temperature and humidity of the environment on the measured temperature value. The temperature and humidity detector 9 measures the temperature and humidity of the area 1 to be detected and transmits the detected temperature and humidity data to the data processing module 31. The temperature calibration unit in the data processing module 31 adjusts the temperature value according to the temperature and humidity of the environment. Here, the adjustment can specifically be appropriately increasing or decreasing the temperature value measured by the temperature detection device 2. In addition, the data processing module 31 further includes an environmental temperature storage unit, which stores the historical temperature information of the area 1 to be detected within several years. The temperature calibration unit in the data processing module 31 can compare the temperature changes in each season of each year to adjust the temperature value measured by the temperature detection device 2. Here, the adjustment can specifically be appropriately increasing or decreasing the temperature value. In order to calibrate the measurement accuracy of the temperature detection device 2 itself, the system further sets a temperature auxiliary measuring device 10, which is connected to the data processing module 31. Its calibration process is as follows: use the temperature auxiliary measuring device 10 to measure the temperature of the fixed temperature reference source and transmit the temperature value to the data processing module 31; then use the temperature detection device 2 to measure the temperature of the fixed temperature reference source, and the data processing module 31 compares the temperature values measured by the two; based on the temperature value measured by the temperature auxiliary measuring device 10, adjust the temperature value measured by the temperature detection device 2. The fixed temperature reference source can be provided by a temperature standard block. For example, if the temperature of the fixed temperature reference source measured by the temperature auxiliary measuring device 10 is 20 °C and the temperature of the fixed temperature reference source measured by the temperature detection device 2 is 18 °C, it means that the temperature error value measured by the temperature detection device 2 is 2 °C. Adjust the measurement parameters of the temperature detection device 2 to make it meet the temperature error accuracy range. In addition, due to the different emissivities of different materials, the measurement parameters of the temperature detection device 2 can be adjusted according to the emissivity of the materials of the dangerous goods containers in the yard to reduce its measurement error.

[0041] In some embodiments, the inner diameter of the nozzle 52 includes: a contraction section 521, the diameter of the contraction section 521 decreasing along the direction from the inlet end to the outlet end of the nozzle 52; a buffer section 522, the diameter of the buffer section 522 being the same as the diameter at the minimum of the contraction section 521; a gradual expansion section 523, the diameter of the gradual expansion section 523 increasing along the direction from the inlet end to the outlet end of the nozzle 52; wherein, the contraction section 521, the buffer section 522 and the gradual expansion section 523 are sequentially connected and arranged along the inlet end to the outlet end of the nozzle 52.

[0042] Specifically, as Figure 2 shown, the inner diameter of the nozzle 52 is successively provided with a contraction section 521, a buffer section 522, and a diffuser section 523 from the inlet end to the outlet end. The diameter of the contraction section 521 decreases in the direction from the inlet end to the outlet end of the nozzle 52. When water passes through the contraction section 521, the velocity increases and the pressure decreases. The diameter of the entire buffer section 522 is consistent and the same as that of the outlet end of the contraction section 521. The flow velocity of water reaches the highest point in the buffer section 522 and the pressure drops to the lowest. The diameter of the diffuser section 523 gradually increases from the inlet end to the outlet end, and can convert the high-speed flowing water into a wider spray angle and a more uniform droplet distribution. This nozzle 52 can generate a high-speed jet flow at a lower pressure, that is, less water can be used to achieve the same coverage effect, improving the utilization rate of water. This nozzle 52 can produce an effective and uniform spraying effect under different water pressures, and will not cause the water flow to be too concentrated under high pressure, so that the dangerous goods container is not damaged by impact.

[0043] In some embodiments, the nozzle 52 further includes a porous spray disc, which is arranged at one end of the diffuser section 523 of the inner diameter of the nozzle 52 facing away from the contraction section 521, and a plurality of spray holes are provided on the porous spray disc.

[0044] Specifically, as Figure 2 shown, a porous spray disc (not shown in the figure) is arranged at one end of the diffuser section 523 facing away from the contraction section 521. The porous spray disc is provided with a plurality of spray holes, and the number and size of the spray holes are not specifically limited here. When water passes through these spray holes, it will be decomposed into small droplets, and the smaller droplets can more evenly cover the temperature anomaly area, reducing local over-wetting and uncovered areas, and improving the utilization rate of water.

[0045] In some embodiments, the temperature detection and spraying system further includes an audible and visual alarm 101, which is connected to the PLC controller 32 and is used to receive the instruction of the PLC controller 32 to emit a sound signal and / or a light signal.

[0046] Specifically, as Figure 1 shown, the temperature detection and spraying system further includes an audible and visual alarm 101. The input end of the audible and visual alarm 101 is signal-connected to the output end of the PLC controller 32. Here, the signal connection can specifically be a wired connection or a wireless connection. When the PLC controller 32 issues a control signal to the spraying device 5, it can also issue a control signal to the audible and visual alarm 101 to trigger a sound signal or a light signal, and remind the surrounding operators through a high-decibel alarm sound and / or a strong flash.

[0047] In some embodiments, the support column 51 includes an upper support column 511 and a lower support column 512. A nozzle 52 is provided at the top end of the upper support column 511, and the end of the upper support column 511 opposite to the nozzle 52 is movably connected to the top of the lower support column 512, so that the upper support column 511 drives the nozzle 52 to slide relative to the lower support column 512 along the extending direction of the support column 51.

[0048] Specifically, as Figure 2 shown, the support column 51 includes an upper support column 511 and a lower support column 512. A nozzle 52 is provided at the top end of the upper support column 511. The upper support column 511 is movably connected to the lower support column 512, and the movable connection here specifically refers to a sliding connection. A chute is provided inside or outside the lower support column 512, and a slider adapted to the chute is provided outside or inside the upper support column 511. The hydraulic cylinder is connected to the upper support column 511 through a piston rod, which can be directly connected or indirectly connected through a connecting rod to transmit pushing and pulling forces, so that the upper support column 511 can be slidably connected to the lower support column 512 through the cooperation of the slider and the chute. In addition, a hydraulic valve can be signal-connected to the PLC controller 32, and the PLC controller 32 controls the extension or retraction of the piston rod of the hydraulic cylinder by reading the position sensor at the position of the nozzle 52, calculates and adjusts the stroke of the piston rod of the hydraulic cylinder according to the preset height requirement of the nozzle 52, and realizes the precise positioning of the upper support column 511. The height of the nozzle 52 of the temperature detection spraying system can be automatically adjusted as needed, improving the flexibility and applicability of the system.
