Description

Technical Field

[0001] This utility model relates to the field of termite control technology for dikes, specifically a termite monitoring device for dikes. Background Technology

[0002] Currently, most reservoirs and dams in China are still earthen structures. One of the major threats to these dams and dams is termites. Termites build nests within these dams, forming extensive tunnels that connect the upstream and downstream sides. In the event of a flood, this can cause leakage and even dam failure. To ensure the structural safety of reservoirs and dams, real-time termite monitoring is necessary. By monitoring termite damage, appropriate control strategies can be developed. With the application of LoRa wireless communication technology, a large number of LoRa-based termite collection devices are installed on reservoirs to detect termite damage. This allows managers to quickly identify termite problems, reduce manual inspection time, and facilitate rapid diagnosis and prevention. Termite monitoring nodes are typically buried underground. These nodes transmit termite colony signals to a monitoring gateway via sensors. The gateway's 4G module and antenna then send the signals to a cloud platform server. Finally, the server processes the data to monitor the termite status of the reservoir dam.

[0003] Currently, when gateway monitoring devices are installed and used, the air humidity around the dam is consistently high, and the device itself needs to be exposed to the outdoors for extended periods. Over time, moisture carrying dust particles and other impurities gradually seeps into the gaps between the gateway's outer casing and slowly enters the interior through the gaps in the outer casing and sealing strips. This affects and causes the electronic components inside the device to malfunction, thus impacting the normal operation of the monitoring equipment. Furthermore, the internal seal is only achieved by the gateway casing and its internal sealing strip pressing against each other. Because maintenance personnel need to periodically remove the device for inspection and data updates, the repeated opening and closing of the gateway casing further widens the gaps between the outer casings and causes the internal sealing strip to shift and lose its elasticity. This further leads to the failure of the sealing strip's compression and sealing effect, which is detrimental to the multi-point deployment and termite monitoring required in the reservoir dam area. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a termite monitoring device for dams. It solves the problem that current monitoring devices, when installed and used, require the device body to be buried deep underground and are only sealed by the top and bottom of the gateway shell and its internal sealing strip. Over time, impurities such as surrounding moisture, dust, and dirt will gradually seep into the gaps between the gateway shell and slowly enter the interior through the gaps in the gateway shell and sealing strip, affecting the normal operation of the monitoring device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a termite monitoring device for dams, comprising a gateway shell, with fixing blocks provided at the four corners of the side of the gateway shell, multiple antennas arranged on one side of the gateway shell, and a 4G module installed inside the gateway shell, which can transmit signals to a cloud platform server through the 4G module and antennas. The gateway shell includes a lower end cover and an upper end cover, with an upper sealing strip and a lower sealing strip respectively pasted around the inner wall of the lower end cover and the upper end cover, and the upper sealing strip and the lower sealing strip are interlocked and fixed together. The upper sealing strip includes a straight strip, the bottom end of which forms an arc-shaped block. An interlocking groove is provided above the arc-shaped block. The overall trajectory of the arc-shaped block gradually increases in curvature from one side to the other side near the interlocking groove, and the upper oblique direction of the arc-shaped block bends towards the interlocking groove. The lower sealing strip includes a side strip, on the side of which a flexible block is formed. A concave groove is formed on the top of the side strip and the flexible block. A protrusion is provided at the end of the flexible block. Multiple deformation holes are equidistantly opened from one side of the protrusion to the other side of the flexible block. The volume of the flexible block gradually narrows and decreases from the root to one side of the protrusion. The flexible block has an arc-shaped structure. The deformation holes are spindle-shaped and are distributed at an angle. The distribution path of the multiple deformation holes changes with the overall curvature of the flexible block.

[0006] Preferably, the gateway housing is made entirely of polyethylene material, and the surface of the fixing block has a circular through hole for fixing screws.

[0007] Preferably, both the upper and lower sealing strips are made of rubber material, and the upper sealing strip is subjected to a hardening treatment.

[0008] Preferably, the back sides of the straight strip and the side strip are respectively glued to the inner walls of the lower end cap and the upper end cap.

[0009] Preferably, the shape of the protrusion matches the shape of the fitting groove, and the protrusion as a whole has a teardrop-shaped structure, while the concave groove matches the overall shape of the arc-shaped block.

[0010] Preferably, the corners of the arc-shaped block, the flexible block, and the protrusion are all rounded.

[0011] This utility model provides a termite monitoring device for dams, which has the following beneficial effects: This invention, through the setting of an upper sealing strip, a lower sealing strip, and a gateway shell, allows the upper end cover to be pressed downwards during the gateway shell fastening process, causing the upper and lower sealing strips to interlock and fit together. At this point, the upper and lower sealing strips are interlocked by the interlocking of protrusions and grooves, and the interlocking of concave grooves and arc-shaped blocks, ensuring that the upper and lower sealing strips are interlocked at multiple inflection points. This effectively avoids gaps and air bubbles between the upper and lower sealing strips, significantly improving the sealing effect. It also prevents the current method of sealing strips being pressed tightly together from top to bottom, which leads to a decrease in sealing effect after long-term use, causing moisture, dust, and dirt from the ground to gradually seep into the gaps between the gateway shells. This further improves the overall sealing effect of the gateway shell, increases its service life, and is beneficial for multi-point deployment and termite monitoring in reservoir dam areas.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] As attached Figure 1 To be continued Figure 7 The termite monitoring device for dams shown includes a gateway housing 1. Fixing blocks 2 are provided at the four corners of the side of the gateway housing 1. Multiple antennas 3 are arranged on one side of the gateway housing 1. A 4G module 6 is installed inside the gateway housing 1, which can transmit signals to a cloud platform server via the 4G module 6 and the antennas 3. The gateway housing 1 includes a lower end cover 11 and an upper end cover 12. Upper sealing strips 4 and lower sealing strips 5 are respectively pasted around the inner walls of the lower end cover 11 and the upper end cover 12, and the upper sealing strips 4 and lower sealing strips 5 are interlocked and fixed together. The upper sealing strip 4 includes a straight strip 41, and an arc-shaped block 42 is formed at the bottom end of the straight strip 41. An interlocking groove 43 is provided above the arc-shaped block 42. The overall trajectory of the arc-shaped block 42 gradually increases in curvature from one side to the other side near the interlocking groove 43, and the upward direction of the arc-shaped block 42 bends towards the interlocking groove 43. With the above arrangement, when the end of the flexible block 52 and the protrusion 54 slide along the surface of the arc-shaped block 42 and gradually fasten and wrap around the outside of the arc-shaped block 42, the design of the overall trajectory of the arc-shaped block 42 allows the protrusion 54 to slide along the surface of the arc-shaped block 42 to the upper side of one side of the arc-shaped block 42, so that it can be more smoothly interlocked into the interior of the interlocking groove 43, further improving the flexibility of their cooperation. The lower sealing strip 5 includes a side strip 51, on the side of which a flexible block 52 is formed. A concave groove 53 is formed above the side strip 51 and the flexible block 52. A protrusion 54 is provided at the end of the flexible block 52. Multiple deformation holes 55 are equidistantly formed on the flexible block 52 from one side of the protrusion 54 to the other. The volume of the flexible block 52 gradually decreases from its root to one side of the protrusion 54. The flexible block 52 has an arc-shaped structure. The deformation holes 55 are spindle-shaped and are distributed obliquely. The distribution path of the deformation holes 55 changes with the overall curvature of the flexible block 52. With the above arrangement, the volume of the flexible block 52 gradually narrows and decreases from the root to one side of the protrusion 54. This allows the arc-shaped block 42 to gradually detach from the interior of the flexible block 52 when the upper cover 12 is removed vertically upwards, thus pulling the flexible block 52. The decreasing volume of the flexible block 52 facilitates the detachment of the arc-shaped block 42 from the surface of the flexible block 52. At the same time, the deformation holes 55 work in sync to further promote the adaptive deformation of the flexible block 52, facilitating the detachment of the two.

[0016] The corners of the arc-shaped block 42, the flexible block 52, and the protrusion 54 are all rounded.

[0017] The gateway housing 1 is made entirely of polyethylene material. The surface of the fixing block 2 has a circular through hole for fixing screws. The upper sealing strip 4 and the lower sealing strip 5 are both made of rubber material. The upper sealing strip 4 is hardened and can be filled with fillers such as carbon black and silica to significantly increase the hardness of the rubber. The back sides of the straight strip 41 and the side strip 51 are respectively glued to the inner walls of the lower end cover 11 and the upper end cover 12. Through the above settings, the overall hardness of the upper sealing strip 4 is greater than that of the lower sealing strip 5, making the lower sealing strip 5 easier to deform and contain. The upper sealing strip 4 can more easily compress the lower sealing strip 5. At the same time, when the two are separated, the upper sealing strip 4 is not easily deformed and maintains its original state, while the lower sealing strip 5 undergoes elastic deformation and separates from the outside of the upper sealing strip 4, further facilitating the separation of the two.

[0018] Please refer to the attached instruction manual for details. Figure 6 The protrusion 54 is adapted to the shape of the fitting groove 43, and the protrusion 54 has an overall teardrop-shaped structure. The concave groove 53 is adapted to the overall shape of the arc block 42.

[0019] The specific implementation method is as follows: Through the above settings, it can be ensured that after the upper sealing strip 4 and the lower sealing strip 5 are fitted together, the protrusion 54 and the fitting groove 43 interlock with each other, and the concave groove 53 and the arc block 42 interlock with each other, thereby ensuring that the upper sealing strip 4 and the lower sealing strip 5 are interlocked together in an alternating manner. This effectively avoids gaps and air bubbles between the upper sealing strip 4 and the lower sealing strip 5, greatly improving the sealing effect between the sealing strips. At the same time, after the upper sealing strip 4 and the lower sealing strip 5 are interlocked, an interlocking force can be generated between them to prevent displacement and loosening of the upper sealing strip 4 and the lower sealing strip 5 from being easily caused by external forces. The interlocking force and the screw fastening force between the gateway housing 1 cooperate with each other to firmly lock and fix the upper end cover 12 and the lower end cover 11.

[0020] The gateway casing 1 houses a Lora-Mesh communication module. The 4G module 6 inside the gateway casing 1 can also communicate with external termite attracting and triggering modules, termite status acquisition modules, controller modules, batteries, release point management circuits, storage modules, and Lora Mesh modules (all of these modules can use existing mature equipment and cooperate with the gateway), forming a large-scale termite colony monitoring system. The termite attracting and triggering module is installed in the soil on the surface of the reservoir dam, while the rest are on the dam surface. The controller module controls the termite nodes. When the device is powered on, the controller module reads the key information from the storage module, then controls the Lora Mesh module to search for and authenticate with the Lora network, establishing a connection with the Lora Mesh communication module. The controller module controls the termite status acquisition module to collect data and sends the data to the Lora Mesh communication module through the Lora Mesh module. The termite nodes are powered by batteries, and the power supply to the termite node devices is controlled by a discharge management circuit, minimizing system power consumption and providing a battery life of up to 3 years. The batteries are replaceable; when the termite nodes receive a low battery warning from the platform, the batteries can be replaced.

[0021] The entire gateway casing 1 is installed in the middle of the reservoir dam. It is powered by a power system consisting of a battery, a charging and discharging control circuit, and a solar charging panel (the installation of the power supply, solar charging panel, and its peripheral circuits can be carried out according to current mature telecommunications technology, and the equipment details and installation steps will not be described here). It is generally installed in the middle of several termite status collection modules. The gateway casing 1 also has two wireless communication modules, both of which are controlled by an ARM controller. The Lora Mesh module collects data from all the multiple termite status collection modules and sends it to the cloud platform server through the 4G module 6 and the antenna 3. The server processes the data and finally realizes the termite status monitoring of the reservoir dam.

[0022] The working principle of this utility model: Step 1: First, the operator aligns the upper cover 12 and the lower cover 11 together and fastens them together.

[0023] Step 2: During the fastening process, press the upper cover 12 downwards with force, causing the bottom arc-shaped block 42 of the upper sealing strip 4 to gradually press upwards towards the flexible block 52. At this time, the flexible block 52 will deform downwards as a whole. Through the design of the outer trajectory shape of the arc-shaped block 42, while pressing the flexible block 52 downwards, the end of the flexible block 52 will shift laterally outwards. At the same time, during the continuous pressing process, the end of the flexible block 52 and the protrusion 54 will slide along the surface of the arc-shaped block 42 and gradually fasten and wrap around the outside of the arc-shaped block 42 until the flexible block 52 is completely wrapped around the outside of the arc-shaped block 42 through the concave groove 53. At the same time, when the protrusion 54 slides and embeds into the fitting groove 43, the process of mutual fitting and fixing of the upper sealing strip 4 and the lower sealing strip 5 is completed. After the upper sealing strip 4 and the lower sealing strip 5 are fixed, the operator can fix the screws one by one to the multiple fixing blocks 2 to further fix and lock the upper cover 12 and the lower cover 11. After completing the multiple fixing steps for the gateway housing 1, the entire gateway housing 1 can be buried underground, with the antenna 3 exposed, following the existing steps. When the entire device is buried deep underground and undergoes long-term monitoring, the upper sealing strip 4 and the lower sealing strip 5 can be fitted together, and the protrusion 54 and the fitting groove 43 can be engaged with each other, as can the concave groove 53 and the arc block 42. This ensures that the upper sealing strip 4 and the lower sealing strip 5 are fitted together in a staggered manner with multiple inflection points, effectively avoiding gaps and air bubbles between the upper sealing strip 4 and the lower sealing strip 5, greatly improving the sealing effect between the sealing strips. This prevents the current method of using the upper and lower sealing strips to press against each other, which leads to a decrease in sealing effect after long-term use, causing moisture, dust, and dirt from the ground to gradually seep into the gaps between the gateway housing 1. This further improves the overall sealing effect of the gateway housing 1 and increases its service life. Finally, the device completes the steps of enhancing the overall sealing effect of the gateway housing 1 and installing the monitoring equipment.

[0024] Step 3: When the equipment needs to be maintained and repaired regularly, the operator first digs out the gateway shell 1 from the ground, unscrews the screws on the gateway shell 1, and at the same time pries up the upper cover 12 to separate the upper cover 12 from the lower cover 11, so that the internal components of the gateway shell 1 can be inspected and maintained. This completes the whole process. Through the above functions, it is beneficial to the multi-point deployment and termite monitoring effect required in the reservoir dam area.
