Description

Technical Field

[0001] The utility model relates to the technical field of termite damage prevention and control, in particular to a probe device used for detecting termite nests of water conservancy projects. Background Art

[0002] Termites are extremely destructive to water conservancy projects. They build nests inside dams, causing the structural strength of dams to decrease. In serious cases, they may even cause dam failure, posing a serious threat to people's lives and property. In my country, there are more than 100,000 reservoirs of various types built, of which 90% are earth-rock dams prone to termite problems. Among the hidden dangers of animal damage to dams found by various river basin management agencies, termite hazards account for 76%. Therefore, termite damage prevention and control is an important part of ensuring the safe operation of water conservancy projects.

[0003] Ant nest excavation is the most thorough and effective termite control measure in many water conservancy projects. At present, there are two main methods: tracing ant paths to dig nests and determining nest locations to dig nests. The tracing ant paths to dig nests requires a large area of ​​excavation on the dam surface, which causes great damage to the dam structure. The method of determining nest locations to dig nests mainly relies on manual inspections, and the nest locations are determined based on the exposed characteristics of termites, such as the distribution images of termite holes and fungal indicators. This method causes less damage to the dam body, but it is highly dependent on manual inspections and empirical judgments, and its accuracy and efficiency are low.

[0004] Therefore, a scientific and efficient method for detecting termite nests is needed to solve this problem. Utility Model Content

[0005] The utility model aims to provide a probe rod device for detecting termite nests in water conservancy projects, so as to improve the detection accuracy and convenience of termite nests.

[0020] The present invention is further described in detail below in conjunction with the embodiments. It should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. used in the text to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] Based on the book "Dyke Termite Control Technology" (author: Mo Jianchu), which introduces the damage of termites to dams and the analysis of termite species and habits, it can be concluded that: 1. The concentration of carbon dioxide in termite nests is about 20-300 times that in the air; 2. The temperature in termite nests is generally maintained between 24℃-26℃; 3. The humidity in termite nests is relatively high, such as the air humidity in the main nest of black-winged earth termites is between 95%-100%, and the air humidity in the main nest of yellow-winged giant termites is between 60%-100%.

[0022] Based on the above principles, the convenience and accuracy of ant nest exploration can be improved by detecting one or more of the soil carbon dioxide concentration, temperature, and humidity.

[0023] like Figure 1 and Figure 2 As shown, this embodiment proposes a probe rod device for detecting termite nests in water conservancy projects, including a rod body 1, a handle 2 is provided at the upper end of the rod body 1, and a pointed cone 3 is provided at the lower end. The pointed cone 3 facilitates the probe rod to break the soil. A closed spherical cavity 4 is provided at the pointed cone end of the rod body 1, and a sensor 5 is provided in the cavity 4. A plurality of vents 6 are provided at the side wall of the cavity 4. The vents 6 enable the interior of the spherical cavity 4 to communicate with the soil environment. The sensor 5 is used to detect one or more of the carbon dioxide concentration, temperature, and humidity in the soil. The sensor 5 in this embodiment can be a temperature and humidity sensor and a carbon dioxide sensor. A controller and a reminder unit are provided at the handle end of the rod body 1. The sensor 5 feeds back the data signal detected from the soil to the control unit. The control unit controls the reminder unit according to the feedback signal. The reminder unit in this embodiment can be an indicator light and a buzzer. Further, a display screen 7 is provided at the upper end of the rod body 1. The controller displays the feedback signal on the display screen 7.

[0024] The use process of the probe is as follows:

[0025] S1. In the season suitable for water conservancy project termite inspection, initially look for the exposed features of termites;

[0026] S2. Preliminarily determine the detection area of ​​the probe according to the exposed characteristics of termites;

[0027] S3. The operator carries the probe rod described in this embodiment to the detection area;

[0028] S4. In the area, every 50-100cm, the handheld probe is inserted downward into the soil. Due to the setting of the vent 6, the environment in the soil is interconnected with the spherical cavity 4 (i.e., temperature, humidity, and carbon dioxide are interconnected). The sensor 5 detects various parameters in the soil and feeds back the detected data to the controller, which makes a judgment;

[0029] If the indicator light is green, it means there is no ant nest in the soil. Pull out the probe and continue to detect the next point. If the indicator light is red and the buzzer alarms, it means there is an ant nest in the soil. Record and display the parameter value.

[0030] S5. Make good marks on the location of the ant nest to facilitate excavation or grouting of the ant nest.

[0031] Since the probe needs to be inserted downward into the soil, preferably, the vent 6 is arranged at the upper part of the center line of the spherical cavity 4 to prevent soil from entering the cavity 4 through the vent 6 during the insertion process; secondly, the present embodiment also has a filter 8 detachably installed at the outer wall of the vent 6 in the cavity 4, and the filter 8 is used to block soil from entering the vent 6. On the one hand, the filter 8 blocks soil from entering the vent 6 during the insertion of the rod body 1, and on the other hand, it can also block soil from entering the vent 6 during the removal of the rod body 1. After step S5 is completed, it can be determined whether the filter 8 needs to be removed for cleaning according to the degree of blockage of the filter 8. Preferably, the filter 8 is detachably installed with screws on the outer wall of the spherical cavity 4.

[0032] The ant nest has a certain depth. When using it, the user hopes that the probe rod is long enough, but when carrying it, the user hopes that the probe rod can be shorter. Therefore, the rod body 1 in this embodiment is designed as a multi-stage adjustable telescopic rod body 1, specifically: the telescopic rod body 1 includes an outer cylinder 101, an inner rod 102 and a fastening bolt 105. The upper end of the outer cylinder 101 is closed and the lower end is open. The handle 2 is arranged at the closed end of the outer cylinder 101. The side wall of the outer cylinder 101 is provided with a screw hole 103 arranged along the axial direction of the cylinder body. The inner rod 102 can enter and exit the outer cylinder 101, and the side wall of the inner rod 102 is provided with a screw hole 2 104 arranged along the axial direction of the inner rod 102. The pointed cone 3 is arranged at the end of the inner rod 102, and the fastening bolt 105 can penetrate the screw hole 103 and the screw hole 2 104. During adjustment, the fastening bolt 105 is pulled out, and after the telescopic adjustment is performed and the screw hole 103 and the screw hole 2 104 are aligned, the fastening bolt 105 is inserted and tightened.

[0033] The above embodiments are only used to explain the concept of the present invention, rather than to limit the protection of the present invention. Any non-substantial changes to the present invention using this concept shall fall within the protection scope of the present invention.
