Description

[0001] DEVICE FOR MEASURING DATA IN DRILL HOLES AND METHOD FOR ITS OPERATION

[0002] The invention relates to a device for measuring data in boreholes with a sensor, a cable section and a measuring head, wherein the measuring head comprises a controller unit, a first cover and a PV module, wherein the first cover is arranged on the controller unit, and wherein the PV module is arranged on the first cover, as well as a method for operating such a device.

[0003] To measure and record data, such as temperature, at different depths in boreholes, a multiple sensor array is typically used, arranged along a flexible cable. This sensor array is positioned vertically in the borehole, and the data collected is recorded as a function of depth. The sensor array is enclosed in a protective casing to shield it from water and other environmental factors.

[0004] Such a sensor chain is shown, for example, in the German patent DE 1020 1001 4415 A1 "Device and measuring method for measuring an underground temperature and use of semiconductor sensors". The sensor chain is surrounded by a tube made of a flexible material, e.g., rubber or plastic.

[0005] The document EP 3464812 B1, "Devices and methods for measuring temperature along a borehole using semiconductor elements," discloses a device for use in measuring temperature in a borehole, comprising: a pipe, which is a metallic pipe, containing a plurality of temperature measuring modules provided at positions along the inside of the pipe. Both devices shown here have the disadvantage of being complicated and therefore expensive to manufacture.

[0006] It is therefore an object of the present invention to provide a device for measuring data in boreholes that is simple, fast and therefore cost-effective to operate in a borehole.

[0007] It is also an object of the present invention to provide a method for operating a device for measuring data in boreholes, with which such a device can be operated simply and reliably.

[0008] The problem is solved by the device according to the invention for measuring data in boreholes. Advantageous embodiments of the invention are also set out in the dependent claims.

[0009] The device according to the invention for measuring data in boreholes comprises a sensor, a cable section, and a measuring head. The sensor is arranged on the cable section. The measuring head includes a controller unit, a first cover, and a photovoltaic module. The first cover is arranged and / or attached to the controller unit, and the photovoltaic module is arranged and / or attached to the first cover. The devices according to the invention are typically used in groundwater monitoring wells. Groundwater monitoring wells usually consist of a well casing inserted into a borehole, surrounded by a protective casing embedded in a concrete base. The measuring head thus combines, in a compact design, the power supply and protection of important components of the device according to the invention, such as the controller unit. Furthermore, the assembly of a unit such as the measuring head is simpler and faster compared to the assembly of the individual components.In a further embodiment of the invention, the controller unit includes a receiver. The receiver is designed and suitable for receiving sensor signals. The sensor signals to be received are those signals sent from the sensor to the controller unit. This can be done via an electrical connection if the cables have appropriate conductors. However, the transmission of the sensor signals from the sensor to the controller unit can also be wireless.

[0010] In a further embodiment of the invention, the controller unit includes a transmitter designed and suitable for sending data to an evaluation and / or control unit. The sensor signals received by the sensor are transmitted and / or sent by the controller unit to an external evaluation unit. This can be done via wired or wireless communication (e.g., WAN, MAN, LAN, LTE). The sensor signals can be modified in this process. For example, an ID identifier of the device according to the invention and / or date or time information can be transmitted along with the sensor signals. Conversion and / or evaluation of the sensor signals within the controller unit is also possible to modify them.

[0011] In an optional embodiment, the controller unit includes a processor unit. The processor unit is designed and suitable for forwarding the received sensor signals to the transmitter. Optionally, the processor unit assigns data to the received sensor signals, including an ID of the device according to the invention and / or information about the acquisition time of the sensor signals. In a further optional embodiment, the processor unit is designed and suitable for processing the received sensor signals and / or evaluating and / or processing them in whole or in part.

[0012] In a further embodiment of the invention, the controller unit has a connection for the cable. This connection is provided for establishing a data and / or power line from the controller unit to the sensor. Data can be transferred to or from the sensor via this connection. Furthermore, the connection can be used to supply power to the sensor. The connection is coupled to the receiver of the controller unit. In a further embodiment of the invention, the controller unit includes an energy storage device. Alternatively, the controller unit can also be coupled to a PV module or another self-sufficient energy source. In a preferred embodiment, the controller unit is coupled to a PV module to generate the energy required for operation and includes an energy storage device to store the electrical energy generated by the PV module.This ensures that the device according to the invention receives the energy required for operation even in bad weather or at night.

[0013] In one embodiment of the invention, the measuring head is coupled to an antenna. The antenna is designed to connect the communication between the device for measuring data in boreholes and an external evaluation unit, and to transfer or receive data from the device according to the invention to an external server or control unit via the antenna.

[0014] In a further embodiment of the invention, the antenna is arranged in the first cover. This has the advantage that the exposed position of the antenna provides good transmission and reception capabilities. Optionally, a protective cover is arranged over the PV module and / or the antenna to protect the PV module and / or the antenna from weather, damage, and mechanical interference.

[0015] In a further embodiment of the invention, the diameter of the first cover is larger than the diameter of the controller unit. This has the advantage that the controller unit can be completely positioned under the first cover. The cover can be used to cover the protective casing of a groundwater monitoring well or the well casing. This protects the controller unit positioned under the cover from all sides. In an optional embodiment, the first cover is designed and suitable for completely covering the controller unit and / or for positioning the controller unit in a pipe for data measurement. For this purpose, the cover is round and has a diameter approximately equal to the pipe diameter. In a further development of the invention, the first cover is designed as a first support. The cover is thus suitable

[0016] A borehole typically comprises a well casing, a protective casing, and optionally other structural elements, such as a concrete base in which the protective casing is cemented, or a protective surround around the borehole. According to the invention, during assembly, a first bracket, on which the controller unit is arranged, is mounted to one of these elements. The cover thus also serves as the fastening element and supports the weight of the device according to the invention.

[0017] In a further development according to the invention, the first cover is designed to be hinged. This allows, for example, access to the well pipe for inspection purposes without having to dismantle the device.

[0018] In a further embodiment of the invention, the device for measuring data in boreholes has a second support. The second support has the advantage that the weight of the device for measuring data in boreholes is borne by two supports, thus reducing the load on each individual support and also relieving stress on the elements that engage with the supports, such as the protective casing or the well casing. Optionally, the second support is arranged differently from and / or at a distance from the first support.

[0019] In one embodiment of the invention, the cable section is attached to the second support. The cable section can either be fixed directly to the second support. In a preferred embodiment, the cable section is arranged in a protective sheath, which can optionally be filled with a shock-absorbing and / or thermally conductive filling material. The second support is then attached to the protective sheath, and the cable section is indirectly attached to the second support via the protective sheath.

[0020] In one embodiment of the invention, the second support is movably designed relative to the first support. This has the advantage that the device according to the invention for measuring data in boreholes can be mounted independently of the specific conditions present at the installation site without further adjustments, and, for example, no modifications are necessary due to changing distances, such as between the protective casing and the well casing.

[0021] In a further embodiment of the invention, the second support is designed as a second cover, which is intended and suitable for covering a pipe. The cable section inserted into the pipe is thus protected from environmental influences. Optionally, the first and second covers are designed differently. This has the advantage that the second cover can be arranged on the well pipe, while the first cover is arranged on the protective pipe. Preferably, the second cover has a smaller diameter than the first cover.

[0022] In a further embodiment of the invention, the first and second covers are designed differently from one another. The first and second covers have different functions. Therefore, it is advantageous to design them differently so that they can optimally fulfill their intended function.

[0023] The problem is further solved by means of the inventive method for mounting a device for measuring data in boreholes at a borehole. Advantageous embodiments of the invention are set out in the dependent claims.

[0024] The inventive method for mounting a device for measuring data in boreholes on a borehole comprises the steps of mounting a first bracket to a structural element of a borehole, inserting a cable section equipped with sensors into a pipe arranged in the borehole, and engaging a second bracket attached to the device with the pipe. A controller unit is arranged on the first bracket. A borehole typically comprises a well casing, a protective casing, and optionally other structural elements, such as a concrete base in which the protective casing is cemented, or a protective surround of the borehole. According to the invention, during assembly, a first bracket, on which the controller unit is arranged, is mounted to one of these elements.In a further step, the cable section equipped with the sensor is inserted into the well casing. Additionally, the second mounting bracket is engaged with a pipe at the drilling site. This pipe can be, for example, the protective casing, the well casing itself, or a pipe from the protective surround. This has the advantage that the device according to the invention is doubly secured and is therefore also suitable for continuous operation.

[0025] In one embodiment of the invention, the first holder is designed as a first cover, which is intended and suitable for covering the pipe. This provides protection for the elements of the device arranged under the cover. Ideally, these are the cable section with the sensor and the controller unit. The cover can be used to cover the protective pipe of a groundwater monitoring well or the well casing.

[0026] In one embodiment according to the invention, the PV module is arranged in the first cover. To avoid cable routing between the controller unit and the PV module, it is advantageous to arrange the PV module close to the controller unit. Preferably, the controller unit is arranged below the cover and the PV module is arranged at the top of the cover.

[0027] The problem is further solved by means of the inventive method for operating a device for measuring data in boreholes at a borehole. Advantageous embodiments of the invention are set out in the dependent claims.

[0028] The inventive method for operating a device for measuring data in boreholes at a borehole comprises the process steps of acquiring a first environmental parameter in a borehole with a sensor of the device, transmitting a first sensor signal generated from the first acquired environmental parameter to a controller unit of the device, receiving the first sensor signal in the controller unit, generating a first data packet from the received first sensor signal, and sending the first data packet to a server unit, wherein the energy for operating the device is provided by a PV module. The inventive method enables autonomous measurement without connection to a power grid. Thus, measurements are also possible at remote measuring points or boreholes where no power supply is available.

[0029] In a further embodiment of the invention, the device is operated continuously. The inventive method makes continuous operation of the device possible for the first time, thus enabling the recording of dynamic processes. Compared to previous methods, where measurements could only be performed at specific points in time because the measuring equipment was installed separately and, above all, only temporarily for each measurement, this opens up entirely new insights. Furthermore, it is now possible for the first time to react to dynamic changes and / or to intervene in a controlling manner.

[0030] In a further embodiment of the invention, multiple environmental parameters are detected by several sensors. For example, the environmental parameters are determined at several depths to capture a temperature distribution over that depth. Alternatively, different environmental parameters such as pressure and temperature are detected. In an optional embodiment, the sensors are identical in construction. In a further optional embodiment of the invention, the sensors are arranged at different positions within the borehole.

[0031] In one embodiment of the invention, data transmission takes place via a cable. Particularly in isolated environments, it is advantageous to use wired communication. Furthermore, it is convenient to provide both the power supply for the sensor and lines for data transfer within a single multi-core cable.

[0032] In one embodiment of the invention, the data packet is transmitted wirelessly to a network server. Although positioning the controller unit within a protective tube also provides some shielding, wireless communication between the network server and the controller unit is possible by positioning the antenna outside the protective tube. This ensures communication over longer distances without the need for complex cabling.

[0033] In a further development of the invention, the network server is not part of the device. The network server can, for example, be a heating system that uses the measured data for control purposes. A central server that aggregates data from several measuring points is also conceivable.

[0034] In one embodiment according to the invention, the controller unit is arranged under a cover. This protects the controller unit from external influences. The cover can also be used to cover the protective casing of a groundwater monitoring well or the well casing. This protects the controller unit arranged under the cover from all sides. In an optional embodiment, the first cover is designed and suitable for completely covering the controller unit and / or for positioning the controller unit inside a pipe for data measurement. For this purpose, the cover is round and has a diameter approximately equal to the pipe diameter.

[0035] In a further embodiment of the invention, the PV module and / or an antenna are arranged in the cover. This has the advantage that the exposed position of the antenna provides good transmission and reception capabilities. Optionally, a protective cover is arranged over the PV module and / or the antenna to protect it from the elements and mechanical damage. The PV module and / or the antenna can be arranged in a recess on the top of the cover. In an alternative embodiment, the antenna is arranged in the well casing and / or the well shaft.Exemplary embodiments of the device according to the invention for recording data in a borehole and of the method for its operation are shown schematically simplified in the drawings and are explained in more detail in the following description.

[0045] Fig. 1 shows a sectional drawing of an embodiment of a device 1 according to the invention for acquiring data in boreholes 200. In this and the further embodiments, the device 1 according to the invention is arranged vertically in a groundwater monitoring well. The borehole 200 is a groundwater monitoring well and has a well casing 230 running parallel to the borehole 200 at its center. The borehole 200 has a circular cross-section and is surrounded by a concrete base 110 as a foundation. The borehole 200 has a protective casing 100 in the aboveground area, which is covered by a cap 120.

[0046] The device 1 comprises a cable section 20 to which sensors 10 are connected at regular intervals. According to the invention, the minimum distance between the sensors 10 is 20 cm. The cable section 20 is a data bus, in particular a digital 2- or 3-wire data bus, through which the individual sensors 10 are connected. The cable section 20 has a total length of at least 10 m, preferably 15 m, particularly preferably 20 m, and most preferably at least 25 m, in order to also acquire data from deep boreholes 200, e.g., wells. In this exemplary embodiment, the length of the cable section is 2030 m.

[0047] In this and all other embodiments, the sensors 10 are humidity and temperature sensors; that is, the sensors 10 detect the humidity and temperature of their immediate surroundings. However, the sensors 10 can also detect other data, such as pressure or chemical composition.

[0048] The cover 210 covers the well pipe 230 and has a feedthrough 34 for the cable section 20. The upper end of the cable section 20 is connected to the measuring head 400, which has a controller unit 160. The data acquired by the sensors 10 can be stored in the controller unit 160 and optionally sent to a server unit 300.

[0049] Fig. 2 shows a sectional drawing of an embodiment of a device 1 according to the invention for recording data in boreholes 200.

[0050] The protective sheath 30 has a connecting element 140 at its second end 32, which is connected to the hook-shaped bracket 130. To mount the device 1, the cable section 20 is inserted into the well pipe 230 and the hook-shaped bracket 130 is engaged with the well pipe 230, in this embodiment being hooked over the edge of the well pipe 230. The protective sheath 30 with the cable section 20 and the sensors 10 is attached to the well pipe 230 by gravity (tensile load). This type of suspension is particularly suitable for temporary data acquisition.

[0051] The measuring head 400 includes a controller unit 160 and a PV module 165, which supplies electrical energy to an energy storage device 164 of the controller unit 160 (see Fig. 3). To protect it from, for example, wild animals, weather conditions, and vandalism, the PV module 165 can have a protective cover 166 made of a transparent material.

[0052] Fig. 3 shows an embodiment of components of the controller unit 160. The controller unit 160 has a receiver 161, which is connected to the cable 20. The receiver 161 is capable of receiving input signals of measurement data from the sensors 10 connected to the cable 20. The input signals are routed to the processor unit 167, which generates an output signal. The output signal generated by the controller unit 160 can be sent to the transmitter 162, which can transmit the output signal to an externally located server unit 300. For this purpose, the controller unit 160 is connected to an antenna 163. The controller unit 160 is supplied with electrical energy by the rechargeable energy storage device 164, which can be charged with electrical energy by a PV module 165 (not shown).

[0053] To operate the device 1, a first environmental parameter of the borehole 200 is detected by a sensor 10 arranged along the cable 20. The sensor 10 generates a first sensor signal and transmits it to the controller unit 160 via the cable 20. The controller unit 160 receives and stores the first sensor signal. Based on this signal, the controller unit 160 creates a first data packet. In this embodiment, the first data packet contains the ID of the sensor 10, the detected temperature, and the time of detection.

[0054] The controller unit 160 sends the first data packet to a server unit 300, with the energy for operating the device being supplied by a PV module 165. The method according to the invention enables autonomous measurement without connection to a power grid. This makes measurements possible even at remote measuring points or boreholes 200 where no power supply is available.

[0055] Similarly, each sensor 10 generates a sensor signal that is sent to the controller unit 160, received there, and stored. In this embodiment, all sensors 10 are identical. The controller unit 160 generates another data packet that also contains the ID of the sensor 10, the measured temperature, and the time of measurement. This data packet is also sent to the server unit 300.

[0056] The acquisition of multiple environmental parameters is thus achieved by multiple sensors 10. For example, environmental parameters are determined at several depths to capture a temperature distribution over that depth. Alternatively, different environmental parameters such as pressure and temperature are recorded. In a further optional embodiment of the invention, the sensors 10 are arranged at different positions in the borehole 200.

[0057] Fig. 4 shows exemplary embodiments of the device 1 according to the invention arranged in a borehole 200. The device 1 and the other components correspond to the device 1 already shown (see Fig. 1 to Fig. 3).

[0058] To mount the device 1, the first bracket 130 is positioned on the protective tube 100 such that it can close the protective tube 100. The controller unit 160 is mounted on the first bracket 130. Then, the cable section 20, equipped with the sensors 10, is inserted into the well pipe 230.

[0059] The second bracket 210 is designed as a cover and is positioned on the well pipe 230 such that the cover 210 completely covers the well pipe 230. The dimensions of the cover 210 are selected accordingly. The cover 210 has a feedthrough 34 for the cable section 20. The cable section 20 is routed through the feedthrough 34 and connected to the controller unit 160. The cable section 20 is arranged vertically within the well pipe 230; its length is adjustable to the length of the well pipe 230.

[0060] The antenna 163 is arranged outside the first bracket 130 and the end cap 120 (Fig. 4) to ensure smooth transmission of the output signals of the controller unit 160 to an external server unit 300.

[0061] Fig. 5 shows exemplary embodiments of the device 1 according to the invention arranged in a borehole 200. The device 1 and the other components correspond to the device 1 already shown (see Fig. 1 to Fig. 3).

[0062] To protect the antenna 163 from, for example, wild animals, the antenna 163 can be located within the end cap 120 itself (Fig. 5a). Furthermore, a photovoltaic module 165 can be mounted on the end cap 120 (Fig. 5b), which supplies the energy storage device 164 with electrical energy. Also to protect it from, for example, wild animals, weather conditions, and vandalism, the photovoltaic module 165 can have a protective cover 166 made of a transparent material.

[0063] Fig. 5c shows an embodiment of the device 1 according to the invention arranged in a borehole 200, wherein the end cap 120 with the measuring head 400 is pivotably attached to the protective tube 100 by means of a hinge. The protective tube 100 and the components arranged therein are therefore accessible but protected. The antenna 163 and the PV module 165 with protective cover 166 are arranged in the end cap 120. The controller unit 160 is arranged below the end cap 120 such that it is positioned inside the protective tube 100. The controller unit 160 is thus protected from, for example, wild animals, weather influences, and vandalism. The length of the cable section 20 and the suspension of the cable section 20 on the cover 210 are advantageously selected such that the cable section 20 is not subjected to tension even when the end cap 120 is open.

[0064] Fig. 6 shows an embodiment of the connection of the device 1 according to the invention, arranged in a borehole 200, with an external server unit 300. The controller unit 160 of the measuring head 400 wirelessly transmits data packets to a server unit 300, where the data packets can be stored and further processed.
