Description

Technical Field

[0001] This utility model relates to the field of ant nest detection technology, and in particular to a termite nest detector. Background Technology

[0002] Termites, as pests that cause serious damage to building structures and timber, are difficult to detect and control early due to their stealth and persistence. Termite nests are usually hidden underground or in building structures. Common detection methods rely on human experience, electronic sensors, or chemical agents, which often require complex circuits and external power supplies, resulting in high costs and difficulty in long-term use in the field or underground soil environments. When conducting long-term underground soil detection, problems such as insufficient power, sensor failure, and battery aging may occur, leading to reduced detection accuracy. Regular battery replacement and maintenance are also required. How to reduce dependence on electricity, thereby extending the service life and maintenance costs of the equipment, and reducing environmental pollution, is an urgent problem to be solved. Therefore, a termite nest detector is proposed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a termite nest detector.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A termite nest detector includes a housing, the outer wall of which is provided with two protective sleeves, the protective sleeves being hollow internally; the interior of the housing is provided with a central cylinder, the bottom end of which is provided with a spring detection structure, and the bottom end of the spring detection structure is provided with a detection needle;

[0006] The top of the housing is provided with a collection chamber, and a gas sensing module is provided inside the collection chamber.

[0007] Furthermore, the two protective sleeves have openings at opposite ends and their internal spaces are connected. A double-layer circular plate is provided between the two protective sleeves. The top and bottom plates of the double-layer circular plate are provided with staggered connecting grooves. The top and bottom plates of the double-layer circular plate can rotate relative to each other.

[0008] The protective sleeve has a cotton thread sensing structure inside.

[0009] Furthermore, the protective sleeve is made of transparent material, and the protective sleeve is connected to the housing by threads.

[0010] Furthermore, the cotton thread sensing structure includes several cotton threads and a gravity block. One end of the cotton thread is fixed to the gravity block, and the other end extends through the protective sleeve to the outside of the protective sleeve. A gravity spring is provided at the end of the gravity block away from the cotton thread, and an indicator rod is provided on the gravity spring.

[0011] Furthermore, the spring detection structure includes a movable block located inside the central cylinder. The bottom end of the movable block is provided with a pressure spring that cooperates with the detection needle, and the top end of the movable block is provided with a connecting rod that passes through the central cylinder.

[0012] Furthermore, the outer wall of the probe is fitted with a conical sleeve, which closes the gap between the central cylinder and the inner wall of the housing through a contraction action.

[0013] Furthermore, the top of the connecting rod is provided with a pressing block, the pressing block is a cylindrical structure, the outer wall of the pressing block is provided with a marking indicator strip, the top of the pressing block is provided with an adjusting sleeve, and the adjusting sleeve is fixed to the pressing block with bolts.

[0014] Furthermore, the collection chamber is equipped with a mounting frame inside, which is a hollow semi-circular structure, and the top of the collection chamber is equipped with a protective cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The detection probe, using a spring-loaded structure, senses sudden changes in soil resistance (reduced density in the anthill area) and directly feeds back mechanical signals to obtain the detection results for the anthill area. This reduces battery consumption and electronic control component failures, significantly improving the long-term reliability of the equipment and avoiding energy consumption and waste issues associated with electronic devices, making it more environmentally friendly. The cotton thread sensing structure utilizes the sinking of a gravity block after absorbing moisture to trigger an indicator rod, synchronously reflecting humidity changes. By observing changes in soil moisture near the anthill area, the detection results are obtained. Especially when the anthill humidity is high, the cotton thread sensing structure effectively reflects changes, thus improving detection accuracy. During detection, no electronic components or external power source are required, facilitating daily inspection and maintenance by users. Its simple operation makes it more suitable for long-term use. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example 1: Refer to Figure 1-4 A termite nest detector includes a housing 100, the outer wall of which is provided with two protective sleeves 200, the protective sleeves 200 being hollow inside;

[0026] The housing 100 has a central cylinder 300 inside, and a spring detection structure 400 is provided at the bottom end of the central cylinder 300. The spring detection structure 400 has a detection needle 407 at the bottom end. The detection needle 407 is a slender cone-shaped body, which is used to facilitate insertion into the underground soil and to continuously penetrate into the soil layer.

[0027] The top of the housing 100 is provided with a collection cavity 101, and a gas sensing module is provided inside the collection cavity 101.

[0028] The two protective sleeves 200 are open at opposite ends and their internal spaces are connected. A double-layer circular plate 201 is provided between the two protective sleeves 200. The top and bottom plates of the double-layer circular plate 201 are provided with staggered connecting grooves 202. The top and bottom plates of the double-layer circular plate 201 can rotate relative to each other. It should be noted that the movement of the probe 407 (the probe is covered with a conical sleeve 404) will cause the conical sleeve 404 to contract in the ant nest area due to reduced resistance, so that a negative pressure space is formed inside the shell 100, which actively sucks in nest gas or soil to the collection chamber 101. The gas sensing module (using test paper or color-changing material) indicates characteristic gases such as carbon dioxide through chemical adsorption / reaction to obtain detection signals. When the conical sleeve 404 is closed, it seals the gap between the shell 100 and the central cylinder 300 to prevent soil particles from entering the internal structure.

[0029] The protective sleeve 200 is equipped with a cotton thread sensing structure 500 inside;

[0030] The protective sleeve 200 is made of transparent material, and the protective sleeve 200 is connected to the housing 100 by threads;

[0031] The cotton thread sensing structure 500 includes a plurality of cotton threads 501 and a gravity block 502. One end of the cotton thread 501 is fixed to the gravity block 502, and the other end extends through the protective sleeve 200 to the outside of the protective sleeve 200. A gravity spring 503 is provided at the end of the gravity block 502 away from the cotton thread 501, and an indicator rod 504 is provided on the gravity spring 503.

[0032] As can be seen from the above design, the device is vertically inserted into the ground through the housing 100. As the device slowly moves downward, the spring detection structure 400 deforms under force, pushing the detection needle 407 deeper. When it reaches the ant nest, because the ant nest has large gaps in its structure, the needle will be subjected to less pressure, which can feed back the change signal and obtain the detection result. When it reaches the ant nest, because the temperature and humidity of the ant nest are higher than the surrounding soil, the cotton thread 501 will absorb more moisture. As the cotton thread 501 absorbs moisture, it will increase its weight, causing the neutral gravity block 502 to sink. The downward movement of the gravity block 502 will cause the gravity spring 503 to bend, thereby triggering the movement of the indicator rod 504. By observing the positional change of the indicator rod 504, the detection signal of the ant nest can be transmitted to the outside. In addition, the rotation of the double-layer circular plate 201 aligns and connects the staggered connecting grooves 202, allowing the internal spaces of the two protective sleeves 200 to connect or operate independently, and obtain the detection results of adjacent layers.

[0033] Example 2: Based on Example 1, the spring detection structure 400 includes a movable block 401 located inside the central cylinder 300. The bottom end of the movable block 401 is provided with a pressure spring 402 that cooperates with the detection needle 407. The top end of the movable block 401 is provided with a connecting rod 403 that passes through the central cylinder 300.

[0034] The outer wall of the probe 407 is fitted with a conical sleeve 404, which closes the gap between the central cylinder 300 and the inner wall of the housing 100 by contraction.

[0035] The top of the connecting rod 403 is provided with a pressing block 405. The pressing block 405 has a cylindrical structure. The outer wall of the pressing block 405 is provided with a marking indicator strip. The top of the pressing block 405 is provided with an adjusting sleeve 406. The adjusting sleeve 406 is fixed to the pressing block 405 with bolts.

[0036] The collection chamber 101 is provided with a mounting frame 102 inside, the mounting frame 102 is a hollow semi-circular structure, and the top of the collection chamber 101 is provided with a protective cover 103.

[0037] As can be seen from the above design, the movable block 401 moves up and down within the central cylinder 300. When the device moves down to detect, the downward detection resistance of the soil near the termite nest changes, the resistance to the detection needle 407 decreases, and the pressure spring 402 pushes the detection needle 407 to a position that creates a gap between the conical sleeve 404 and the internal space of the housing 100. As the device continues to move down until it leaves the termite nest layer, the gap creates soil near the termite nest. The gas components in the soil enter the gas sensing module through the collection chamber 101, where they are collected and a detection result is generated. During this process, by adjusting the sleeve 406, the user can manually adjust the maximum or minimum gap size between the detection needle 407 and the internal space of the housing 100 to adapt to different soils or building materials.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
