Description

Technical Field

[0001] The invention relates to the technical field of moisture content detection of live combustibles, and in particular to a distributed live combustible moisture content monitoring device. Background Art

[0002] The moisture content of live combustibles is a key indicator for measuring the forest fire risk level. It plays a vital role in forest fire prevention and forest ecological environment monitoring. Traditional methods for measuring the moisture content of live combustibles mainly include drying weighing method, resistance method, capacitance method, etc.

[0003] Although the drying weighing method can provide relatively accurate measurement results, it is a destructive measurement method. This method requires sample collection, and the entire measurement process is cumbersome, complicated, and time-consuming, and it cannot meet the needs of real-time online monitoring at all. The resistance method and the capacitance method use the relationship between the electrical properties of wood and the moisture content to measure the moisture content. These methods are easily affected by many environmental factors such as wood type, temperature, and humidity, resulting in limited measurement accuracy, and the measurement range is relatively small, which makes it difficult to meet the comprehensive monitoring requirements of different types of trees in large areas of forests. Therefore, technical personnel in this field provide a distributed live combustible moisture content monitoring device to solve the problems raised in the above background technology. Summary of the invention

[0037] like Figure 2 , 4 As shown in FIG7 , a connection structure 104 is provided at the upper ends of the two frames 101. The connection structure 104 includes a steel belt 1041. The steel belt 1041 is spirally arranged. The end surfaces of the steel belt 1041 at both ends are respectively fixedly connected with a Velcro male layer 1042 and a Velcro female layer 1043. The lower end surface of the steel belt 1041 is provided with four first grooves 1044. The lower parts of the four first grooves 1044 are fixedly connected with a first connecting rod 1045. The upper end surfaces of the two frames 101 are provided with two second grooves 1046. The upper parts of the four second grooves 1046 are fixedly connected with a second connecting rod 1047.

The steel belt 1041 is wrapped around the tree trunk, and the steel belt 1041 is fixed to the tree trunk after the Velcro male layer 1042 and the Velcro female layer 1043 are adhered to each other. Then, the steel belt 1041 is connected to the two frames 101 by hanging the eight hooks 1049 on the four first connecting rods 1045 and the four second connecting rods 1047 respectively, so that the two frames 101 are subjected to the traction force of the steel belt 1041, thereby improving the stability after installation.

[0038] like Figure 2 ,3 As shown in FIG5 , the upper and lower ends of the front inner wall of the frame 101 at the front and the upper and lower ends of the rear inner wall of the frame 101 at the rear are fixedly connected with a support structure 105, and the support structure 105 includes an outer tube 1051, and a storage groove 1052 is opened at one end of the outer tube 1051. A spring 1053 is fixedly connected inside the storage groove 1052. The other end of the spring 1053 is fixedly connected to an inner rod 1054. The other end of the inner rod 1054 passes through the storage groove 1052 and passes to the outer tube 105. 1, and a clamping plate 1055 is fixedly connected to the end, and multiple clamping plates 1055 are fitted on the tree trunk, and then the eight inner rods 1054 are squeezed to move the eight inner rods 1054 to the inside of the eight outer tubes 1051, and the eight springs 1053 are squeezed. The eight inner rods 1054 are pushed to move outside the eight outer tubes 1051 through the tension of the eight springs 1053 themselves, and the eight clamping plates 1055 are close to the tree trunk and located at the center between the two frames 101, which is easy to install.

[0039] The first detection device 1 and the second detection device 2 are configured identically. The second detection device 2 is smaller than the first detection device 1. The tree trunk is detected by the first detection device 1 having a larger size, and the tree branches are detected by the second detection device 2 having a smaller size.

[0040] Working principle: When in use, wrap the steel belt 1041 around the tree trunk, and fix the steel belt 1041 on the tree trunk after the Velcro male layer 1042 and the Velcro female layer 1043 are pasted to each other. By rotating the two frames 101, the two frames 101 are sleeved on the tree trunk, and the two mounting plates 103 are fixed by bolts to connect the two frames 101. A plurality of plywoods 1055 are fitted on the tree trunk, and then the eight inner rods 1054 are squeezed to move the eight inner rods 1054 toward the inside of the eight outer tubes 1051, and the eight springs 1053 are squeezed to push the eight inner rods 1054 toward the outside of the eight outer tubes 1051 through the tension of the eight springs 1053 themselves, and the eight plywoods 1055 are close to the tree trunk and located at the center between the two frames 101 for easy installation.

The microwaves received by the multiple microwave receiving modules 110 are transmitted to two integrated chip boards 1022, and the microwave signals are processed by the two integrated chip boards 1022. Wood is a complex medium composed of multiple components such as cellulose, hemicellulose and lignin. There is a close and subtle relationship between the dielectric constant and moisture content of wood. When microwaves propagate in tree trunks or branches, their electric field will interact strongly with water molecules in the wood. This process will cause a significant change in the propagation characteristics of microwaves, which is mainly reflected in the amplitude attenuation and phase change of the microwave signal, thereby obtaining the moisture content of the tree.

[0043] Since the tree is located between the two frames 101 , the distance between the two frames 101 and the tree is monitored in real time by the first ultrasonic distance measuring sensor 108 and the second ultrasonic distance measuring sensor 109 , so as to measure the diameter of the tree.

[0044] Then, by opening the four buckles 10212 and flipping down the two protective shells 10211, the two small solar panels 1027 are exposed, and the four second micro-electric telescopic rods 1029 are controlled to extend, and the four second micro-electric telescopic rods 1029 push the four first micro-electric telescopic rods 1025 to rotate, and then the four first micro-electric telescopic rods 1025 are controlled to extend, and the four first micro-electric telescopic rods 1025 push the two small solar panels 1027 to rotate, and the four second micro-electric telescopic rods 1029 cooperate with the four first micro-electric telescopic rods 1025 to push the two small solar panels 1027 to a tilted state, and then two rectifiers and voltage regulators are used to control the four second micro-electric telescopic rods 1029 to extend, and the four first micro-electric telescopic rods 1025 to push the two small solar panels 1027 to a tilted state. The device 1023 rectifies and stabilizes the electric energy generated by the two small solar panels 1027 and then transmits it to the battery module 1021 for storage, so as to power the equipment. When carrying, the two small solar panels 1027 are stored in the two third grooves 111 by controlling the contraction of the four second micro-electric telescopic rods 1029 and the four first micro-electric telescopic rods 1025, and then the two protective shells 10211 are flipped upwards, and the hanging rods on the four buckles 10212 are hung on the four hooks 10213 to limit the two protective shells 10211, thereby protecting the two small solar panels 1027.
