[0002] The intelligent micro-environment monitoring terminal is a smart sensing device used for urban manhole cover management. It integrates multiple sensors to monitor manhole cover displacement and tilt status in real time, as well as environmental parameters such as underground water level, harmful gases, temperature, and humidity. Utilizing IoT technology, the intelligent micro-environment monitoring terminal enables wireless data transmission. Abnormal situations can be instantly pushed to the management platform or mobile devices, helping municipal departments respond quickly to issues such as missing manhole covers, flooding, and excessive gas levels.

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] It should be noted in advance that the intelligent microenvironment monitoring terminal in one embodiment of this utility model can be applied to the intelligent monitoring of the underground microenvironment. For example, after the intelligent microenvironment monitoring terminal of this utility model is installed on a manhole cover, its built-in sensing unit can monitor parameters such as manhole cover displacement, tilt status, underground water level, harmful gases, temperature, and humidity to ensure the safety of urban public facilities. It is understood that the above is not a limitation on the application scenarios of the intelligent microenvironment monitoring terminal in this embodiment; the intelligent microenvironment monitoring terminal of this utility model can also be applied to other similar application scenarios. The intelligent microenvironment monitoring terminal of this utility model will be further described below.

[0034] Reference Figure 1In one embodiment of this utility model, the intelligent microenvironment monitoring terminal includes a host 1 and an expansion module 2 detachably installed on the host 1. The expansion module 2 integrates a sensing unit. When the expansion module 2 is installed in the same position as the host 1, the host 1 and the sensing unit establish a signal transmission path for microenvironment monitoring. The expansion module 2 can be equipped with different types of sensing units according to actual monitoring needs. For example, the expansion module 2 can be expanded to include functions such as smoke detection, natural gas detection, and human body detection, further improving the monitoring effect of the downhole microenvironment.

[0035] Reference Figure 1 and Figure 2 A first sealing element 3 is provided between the main unit 1 and the expansion module 2. When the expansion module 2 is installed in the same position as the main unit 1, the expansion module 2 and the main unit 1 together press against the first sealing element 3 to form a sealed space, within which the signal transmission path is located. Due to the high complexity of the downhole microenvironment, substances such as liquids or gases may intrude and damage the signal transmission path, causing the connection between the expansion module 2 and the main unit 1 to fail. In this embodiment, the sealed space formed by the main unit 1 and the expansion module 2 pressing against the first sealing element 3 reduces the damage to the signal transmission path caused by the downhole microenvironment, ensuring the normal operation of the intelligent environmental monitoring terminal. In this embodiment, the first sealing element 3 can be made of rubber material and can be annular.

[0036] Reference Figure 3 The host 1 includes a first housing 11 and a first electrical connector 12 installed within the first housing 11. The expansion module 2 cooperates with the first electrical connector 12 to establish a signal transmission path. Specifically, the expansion module 2 includes a second housing 21 and a second electrical connector 22 installed within the second housing 21. The second electrical connector 22 can be electrically connected to the first electrical connector 12 to establish a signal transmission path.

[0037] Reference Figure 3 and Figure 4 In one optional embodiment, a second sealing element 4 is further provided between the first housing 11 and the first electrical connector 12. When the expansion module 2 is installed in the mounting position of the host 1, the expansion module 2, the first housing 11, and the first electrical connector 12 simultaneously press against the first sealing element 3 and the second sealing element 4 to form a sealed space.

[0038] Reference Figure 3 and Figure 4 In one optional embodiment, a third sealing element 5 is further provided between the second housing 21 and the second electrical connector 22. When the expansion module 2 is installed in the mounting position of the host 1, the host 1, the second housing 21 and the second electrical connector 22 simultaneously press against the first sealing element 3 and the third sealing element 5 to form a sealed space.

[0039] Reference Figure 3 and Figure 4 In this example, a second sealing element 4 is provided between the first housing 11 and the first electrical connector 12, and a third sealing element 5 is provided between the second housing 21 and the second electrical connector 22. When the expansion module 2 is installed in the mounting position of the host 1, the first housing 11, the second housing 21, the first electrical connector 12, and the second electrical connector 22 simultaneously press against the first sealing element 3, the second sealing element 4, and the third sealing element 5 to form a sealed space.

[0040] Specifically, by pressing the first housing 11, the second housing 21, the first electrical connector 12, and the second electrical connector 22 against the first seal 3, the second seal 4, and the third seal 5, the corresponding seals can undergo a certain deformation and fully abut against the first housing 11, the second housing 21, the first electrical connector 12, and the second electrical connector 22. This ensures the airtightness of the sealed space, guarantees the effectiveness of the signal transmission path connection, and ensures the normal operation of the expansion module 2. It is understood that the second seal 4 and the third seal 5 can also be made of rubber material and can both be annular.

[0041] Reference Figure 4 Specifically, on two opposing surfaces of the first housing 11 and the second housing 21, one surface has a protrusion and the other surface has a recess. The protrusion can be partially inserted into the recess to form an installation space between the protrusion and the recess. The first sealing member 3 is installed in the installation space. When the expansion module 2 is fitted into the mounting position of the main unit 1, it can press against the first sealing member 3 to form a sealed space.

[0042] Reference Figure 3 and Figure 4 In this embodiment, the first electrical connector 12 includes a contact plate 121 with multiple electrical contact points, and the second electrical connector 22 includes a control plate 221 and a spring pin 222 electrically connected to the control plate 221. The spring pin 222 can contact the electrical contact points to form a signal transmission path. The first housing 11 has an electrical connection port 111 that exposes a portion of the contact plate 121. The second housing 21 includes an annular portion 211, which can be inserted into the electrical connection port 111. The spring pin 222 is located within the hollow cavity of the annular portion 211 and can be used to protect the spring pin 222.

[0043] Reference Figure 3 and Figure 4One side of the contact plate 121 can abut against the first housing 11. It is understood that the first housing 11 and the contact plate 121 can be fitted with the aforementioned protrusions or recesses to form an installation space, in which the second seal 4 is installed. Similarly, the control plate 221 can abut against the second housing 21, and the two can also cooperate in the aforementioned manner to form an installation space for the installation of the third seal 5. Of course, in other embodiments, the aforementioned installation space may not be provided. Compared to connecting the expansion module 2 and the host 1 via a wiring harness, in this embodiment, the communication connection between the expansion module 2 and the host 1 does not increase the complexity of the downhole microenvironment, and the connection stability is good.

[0044] Reference Figure 1 and Figure 4 In one embodiment of this utility model, the intelligent micro-environment monitoring terminal further includes an elastic buckle 6 disposed on one of the main unit 1 and the expansion module 2, and a slot 7 disposed on the other of the main unit 1 and the expansion module 2. When the elastic buckle 6 is engaged in the slot 7, the expansion module 2 is positioned to cooperate with the installation position of the main unit 1. In this embodiment, the example of the expansion module 2 having the elastic buckle 6 and the main unit 1 having the slot 7 is used for illustrative purposes, and this is not a limitation on the position of the spring buckle and the slot 7 in this application. In other embodiments, the elastic buckle 6 may also be disposed on the main unit 1, and the slot 7 may be located in the expansion module 2. The design of the elastic buckle 6 ensures quick installation between the expansion module 2 and the main unit 1. When the elastic buckle 6 is locked, it can also drive the first housing 11 and the second housing 21 to press against the first sealing member 3 to ensure the sealing performance of the sealed space.

[0045] Reference Figure 1 and Figure 4 The main unit 1 has a recessed mounting groove 112 for accommodating the expansion module 2. A slot 7 is formed on the inner wall of the mounting groove 112 at a relative position. The expansion module 2 is provided with an elastic buckle 6 corresponding to the slot 7. When the expansion module 2 is installed in the mounting position of the main unit 1, the elastic buckle 6 has elastic potential energy to engage with the slot 7. In this embodiment, the elastic buckle 6 can be driven to deform, moving closer to or further away from the second housing 21. After the expansion module 2 is installed in the mounting groove 112, the elastic buckle 6 can move away from the second housing 21 and engage with the slot 7 of the main unit 1, thus completing the quick installation of the expansion module 2 and improving the overall integrity and connection reliability of the expansion module 2 and the main unit 1.

[0046] Reference Figure 1On a plane perpendicular to the depth direction of the mounting slot 112, the vertical projection of the mounting slot 112 is an irregular shape, allowing the expansion module 2 to be positioned and fitted into the mounting slot 112. That is, the projection image of the mounting slot 112 on the corresponding plane matches the shape of the expansion module 2, ensuring rapid positioning and alignment of the expansion module 2 with the mounting slot 112. Exemplarily, in an optional embodiment, the wall of the mounting slot 112 is provided with a positioning surface adapted to the shape of the expansion module 2. This positioning surface can be formed by cutting the wall of the mounting slot 112 with a cross-section perpendicular to the plane containing the opening of the mounting slot 112. When installing the expansion module 2, it can be quickly installed by aligning it with the positioning surface, thus improving the ease of installation of the expansion module 2 onto the host computer 1.

[0047] In one optional embodiment, a positioning protrusion and a positioning groove are provided between the host 1 and the expansion module 2. The positioning protrusion and the positioning groove have a foolproof function, which can ensure the precise docking of the expansion module 2 and the host 1.

[0048] Reference Figure 1 In one optional embodiment, the intelligent micro-environment monitoring terminal further includes a fastener 8 for fixing the host 1 and the expansion module 2. When the intelligent micro-environment monitoring terminal of this embodiment is applied to an environment with strong vibration, the fastener 8 can increase the tightness of the installation between the expansion module 2 and the host 1, and resist external vibration and damage. Specifically, the fastener 8 can be a screw, which, in conjunction with mounting holes opened in the first housing 11 or the second housing 21, can strengthen the tightness of the installation between the expansion module 2 and the host 1, so as to ensure the effective connection between the two.
