Description

Technical Field

[0001] This utility model belongs to the field of groundwater monitoring technology and relates to a groundwater monitoring device that supports satellite communication. Background Technology

[0002] Groundwater monitoring can assess regional water resource reserves and sustainability, providing a scientific basis for rational development and utilization. Currently, groundwater monitoring in the industry mainly relies on public mobile networks for data communication. However, in some remote areas, or when mobile networks fail due to various reasons—such as natural disasters—the normal uploading of on-site data cannot be guaranteed.

[0003] Secondly, because groundwater monitoring equipment needs to be placed inside groundwater inlet protection devices, the long-term humid environment is extremely damaging to electronic products. Some products in the industry have attempted to address the damage caused by groundwater vapor by integrating the traditional separate power supply system, sensors, and data terminals into an integrated structure. However, in practical applications, few products have effectively solved the problem of moisture damage.

[0004] Finally, most current designs on the market focus on preventing groundwater and water vapor from entering electronic devices, without considering the possibility of water seepage from artesian wells, or the waterproofing of electronic components in extreme situations where the entire wellhead protection device is flooded. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes a groundwater monitoring device that supports satellite communication, allows for the installation of a satellite communication module, and meets IP68 waterproofing requirements.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A groundwater monitoring device supporting satellite communication includes a wellhead protection device and an integrated groundwater data acquisition device installed on top of the wellhead protection device. The integrated groundwater data acquisition device includes an electronic compartment and a battery compartment connected below the electronic compartment. The electronic compartment includes a hemispherical radome and a bottom mounting plate. A waterproof sealing element is provided between the hemispherical radome and the top of the battery compartment. The battery compartment is located inside the wellhead protection device and contains a battery. The upper edge of the battery compartment is installed on top of the wellhead protection device, and a waterproof connector is provided at the bottom of the battery compartment. The wellhead protection device includes a top cover and a barrel body. A sealing partition plate is horizontally arranged inside the barrel body, and a sealing plate support platform is provided inside the barrel body. The sealing partition plate is connected to the sealing plate support platform, and a waterproof sealing element is provided between the sealing partition plate and the sealing plate support platform. A wire-passing hole is provided on the sealing partition plate, and a watertight head is installed at the wire-passing hole. A louver is provided on the barrel body, and an opening is provided at the bottom of the barrel body.

[0007] Furthermore, the waterproof sealing element disposed between the hemispherical radome and the top of the battery compartment includes a first rubber gasket and an O-ring.

[0008] Furthermore, the waterproof sealing element provided between the sealing partition plate and the sealing plate support platform is a second rubber gasket.

[0009] Furthermore, the bottom of the radome is provided with several mounting screw holes, and the top of the battery compartment has mounting holes corresponding to the mounting screw holes. The radome and the battery compartment are connected by anti-theft screws.

[0010] Furthermore, the bottom mounting plate is mounted on top of the battery compartment.

[0011] Furthermore, an insect-proof net is installed inside the louvers, and at least one louver is lower than the sealing partition.

[0012] Furthermore, the electronic compartment is equipped with a Beidou antenna, a Beidou module, a 4G communication module, a 4G antenna, and an RTU. The Beidou antenna is connected to the Beidou module, the 4G antenna is connected to the 4G communication module, and both the Beidou module and the 4G communication module are connected to the RTU.

[0013] Furthermore, the bottom mounting plate is also provided with two layers of mounting brackets, and the Beidou antenna is mounted on the higher mounting bracket.

[0014] Furthermore, a Bluetooth switch is also provided at the bottom of the battery compartment. The Bluetooth switch is connected to the RTU and is used to control the Bluetooth function of the RTU to be turned on or off.

[0015] Furthermore, it also includes a pressure level gauge, which is electrically connected to the RTU via a watertight head and a waterproof connector.

[0016] The beneficial effects of this utility model are as follows: The groundwater monitoring equipment provided by this utility model realizes satellite communication function and has the functions of sealing and waterproofing electronic components, allowing the well to be breathable and preventing water pollution.

[0017] This invention employs a detachable sealing partition to divide the barrel into upper and lower layers. The upper layer is designed to regulate and balance the temperature and humidity of the instrument compartment and prevent insect intrusion, thus providing the best possible operating environment for the instruments. The lower layer not only balances the air pressure inside the well but also ensures the performance and safety of the sensors. The rubber gaskets and watertight caps used in installing the partition are waterproof, effectively preventing moisture from the lower space from entering the upper space. Even in extreme cases of groundwater inrush, the sealing partition prevents well water from entering the upper space, and the lower layer's louvers allow water to drain out through the wellhead protection device, ensuring the safety of the instruments in the upper space. Even in extreme situations such as groundwater inrush or flooding of the station, data security is protected to the greatest extent possible. The sealing partition is detachable, allowing for maintenance work inside the well when the entire wellhead protection device cannot be moved.

[0018] The semi-circular radome design not only meets the special structural requirements of satellite antenna installation but also provides good physical structure and protection, while also considering aesthetics and preventing injury to people and animals. Furthermore, the 12 sets of anti-theft screws, waterproof rubber gaskets, waterproof O-rings between the radome and the mounting plate, as well as the waterproof buttons and connectors at the bottom of the battery compartment, ensure that the integrated groundwater data acquisition device meets IP68 waterproof requirements. This ensures that even if the internal sealing partition of the wellhead protection device fails, or even in extreme cases where the entire groundwater monitoring station is submerged, no water will seep into the groundwater data acquisition device, effectively preserving station data and ensuring equipment safety.

Detailed Implementation

[0026] The technical solution provided by this utility model will be described in detail below with reference to specific embodiments. It should be understood that the following specific embodiments are only used to illustrate this utility model and are not intended to limit the scope of this utility model.

[0027] like Figure 1 As shown, the groundwater monitoring device supporting satellite communication provided by this utility model includes an integrated groundwater data acquisition device 1 and a wellhead protection device 2. The integrated groundwater data acquisition device 1 is installed on top of the wellhead protection device 2, and the bottom of the integrated groundwater data acquisition device 1 is inserted into the wellhead protection device 2.

[0028] like Figure 2 , Figure 3As shown, the integrated groundwater data acquisition device 1 includes an electronic compartment 101 and a battery compartment 102. The electronic compartment 101 is hemispherical in shape and includes a hemispherical radome 103 and a bottom mounting plate 104. The electronic compartment 101 has space to accommodate the Beidou antenna and other electronic components. Mounting brackets 105 for various electronic components are mounted on the bottom mounting plate 104. The bottom of the radome 103 has 12 mounting screw holes 106, corresponding to the mounting holes around the top of the battery compartment 102 on the outer periphery of the bottom mounting plate 104. Anti-theft screws are used to connect the radome 103 and the top periphery of the battery compartment 102 together. Between the radome 103 and the top of the battery compartment 102, there is not only a first rubber gasket 107 for waterproofing, but also a waterproof O-ring 108. Specifically, the first rubber gasket 107 is located near the outer edge of the connection surface between the radome 103 and the battery compartment 102, forming the first layer of waterproofing, and the waterproof O-ring 108 is located near the inner edge of the connection surface between the radome 103 and the battery compartment 102, forming the second layer of waterproofing. A bottom mounting plate 104 is installed on top of the battery compartment 102. The battery compartment 102 is cylindrical and houses the battery. Its top sealing cover serves as the bottom of the bottom mounting plate of the electronic compartment. The bottom contains a Bluetooth switch 109 and several sensor connectors 110. Both the Bluetooth switch 109 and the sensor connectors 110 are waterproof. The sensor connectors form an electrical connection with the battery, preferably using waterproof male and female connectors. A pre-drilled hole 111 can also be provided at the bottom of the battery compartment for mounting additional connectors or expanding wiring. When not in use, the pre-drilled hole 111 should be sealed with a plug or other waterproof structure. This invention uses a lithium battery. Considering that lithium batteries are prone to performance fluctuations when subjected to external vibrations, a buffer component, such as a shock-absorbing spring, is preferably provided below the battery to reduce vibration and increase the safety factor. The electronic compartment houses a Beidou antenna 112, an RTU acquisition unit (LDRTU7000), a Beidou communication module (SKG172T), a 4G communication module (ME909s-821), and a 4G antenna, all of which are mounted on a mounting bracket. It should be noted that the above component models are only one feasible embodiment and should not be considered as limiting the present invention. In practical applications, other models can be selected based on site conditions and component compatibility. Figure 2 , Figure 3 The mounting bracket has two layers, one high and one low. The BeiDou antenna is mounted on the higher bracket, while the RTU acquisition unit, BeiDou communication module, and 4G communication module are all mounted on the lower bracket. The 4G antenna is preferably a patch antenna, which is small in size and can be directly attached to the inside of the antenna cover during installation. Figure 6As shown, the BeiDou antenna is connected to the BeiDou communication module, and the 4G antenna is connected to the 4G communication module. Both the BeiDou and 4G communication modules are electrically connected to the RTU acquisition unit. The battery is connected to the RTU acquisition unit and supplies power to other units through the RTU. The battery can also directly power the components. The RTU acquisition unit has Bluetooth functionality, and a Bluetooth switch is connected to the RTU acquisition unit, allowing control of the RTU acquisition unit's Bluetooth function without disassembling the electronics compartment.

[0029] like Figure 4 As shown, the wellhead protection device 2 is cylindrical in shape, including an anti-intrusion top cover 201, a barrel body 202, a sealing partition plate 203, insect-proof louvers 204, and a mounting base 205. The anti-intrusion top cover 201 is installed on top of the barrel body 202, with an assembly hole 211 in the middle for inserting the integrated groundwater data acquisition device 1. Safety locks 206 and rotating shaft connectors 207 are arranged at both ends of the anti-intrusion top cover 201 along its diameter. The operating end of the safety lock is hidden on the back of the top cover, making it difficult to detect, and can be further enhanced with special bolts or dedicated locks. The bottom of the entire wellhead protection device is fixed to the ground. After the safety lock is installed on the top cover, the wellhead protection device can effectively protect the wellhead when the top cover is locked. The sealing partition plate 203 is horizontally arranged in the middle of the barrel body 202, dividing the barrel body 202 into upper and lower layers. Specifically, as... Figure 5 As shown, the sealing partition plate 203 has several mounting holes evenly arranged along its circumference, and a sealing plate support platform 208 is provided in the center of the barrel body 202. The sealing plate support platform 208 is annular and has through holes corresponding to the mounting holes on the partition plate. The partition plate is fixed to the sealing plate support platform with fastening screws. A second rubber gasket 209 is provided between the sealing partition plate 203 and the sealing plate support platform 208 to provide a seal. The sealing partition plate 203 has a wire hole 210 for threading wires and installing a watertight head 213 that can prevent pressurized water. The barrel body 202 has four louvers 204, and stainless steel insect-proof mesh 212 is installed inside the louvers 204. The sealing partition plate divides the internal space of the barrel body into upper and lower layers, each containing two insect-proof louvers. The function of the upper louvers is ventilation and heat dissipation, while when groundwater surges, water can be discharged through the lower louvers to the wellhead protection device. The bottom of the barrel 202 is a circular mounting base with evenly distributed mounting holes for fixing it to the ground. The bottom of the barrel 202 has an opening and is not sealed.

[0030] This utility model provides a groundwater monitoring device supporting satellite communication. The main components are made of galvanized carbon steel and stainless steel, making it sturdy, durable, and resistant to corrosion. During installation, the integrated groundwater data acquisition device 1 and the wellhead protection device 2 are first assembled. Then, the battery compartment of the integrated groundwater data acquisition device 1 is inserted into the mounting hole at the top of the wellhead protection device 2, with the electronic compartment protruding from the top of the wellhead protection device 2. The battery compartment is then fixed to the top cover of the protective cylinder (the upper edge of the battery compartment has an extended platform, which is fixed to the top cover of the protective cylinder using nuts and mounting holes). When it is necessary to inspect the electronic compartment, battery compartment, or check the condition inside the wellhead, the safety lock can be opened, and the top cover can be lifted, allowing the integrated groundwater data acquisition device and the top cover to be opened together. A dedicated cable (which transmits signals in addition to power) for monitoring groundwater, located in the well below the wellhead protection device 2, is connected to the sensor connector at the bottom of the integrated groundwater data acquisition device 1 via a watertight connector in the sealed partition plate 203. The signals acquired by the sensor element are transmitted to the RTU acquisition unit. The sensor element in this invention is a pressure level gauge. In addition to the power cable, the external pipeline of the pressure level gauge also includes a vent pipe. The pipeline of the pressure level gauge exits from the wellhead, passes through a watertight head in the sealed partition plate, and then enters the upper part of the sealed partition plate. The power cable connects to the sensor connector at the bottom of the integrated groundwater data acquisition device, while the vent pipe remains in the upper space of the sealed partition plate. Due to the louver design, the upper space of the sealed partition plate is open to the atmosphere, ensuring water pressure balance and enabling accurate measurement by the pressure level gauge. The battery in the battery compartment powers the sensor element through the RTU acquisition unit. The RTU acquisition unit performs satellite communication via a Beidou module and Beidou antenna, and mobile communication via a 4G communication module and 4G antenna. Thus, the RTU acquisition unit can transmit sensor signals to the control center or receive control signals sent by the control center.

[0031] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
