Description

Technical Field

[0001] This invention belongs to the field of temperature measurement and monitoring technology for large-volume water storage bodies, specifically relating to an intelligent temperature measurement and maintenance device and its working method suitable for large-scale hot water storage bodies. Background Technology

[0002] Large-capacity pool-type thermal energy storage technology, as a highly efficient large-scale thermal energy storage method, has expanded its application scope from early solar seasonal thermal storage to various scenarios such as industrial waste heat recovery, load peaking in thermal power plants and regional heat source plants. With the diversification of application scenarios, the scale of thermal energy storage pools has also increased significantly, with storage capacity growing from approximately 10,000 cubic meters to hundreds of thousands of cubic meters, and even reaching ultra-large-scale projects with a capacity of 100 million cubic meters. To achieve huge thermal storage capacity within limited terrain area, the depth of the pools has continuously increased, from approximately 10 meters to 30 meters or even deeper. Significant temperature stratification (thermal stratification) occurs in the water body along the depth direction, and accurately understanding its temperature field distribution is crucial for system performance evaluation and operational optimization. However, with the increase in pool volume and depth, existing monitoring technologies are insufficient to meet the requirements for real-time, accurate, and reliable measurement, mainly due to the following problems: 1. Existing maintenance manholes have a single function and cannot support integrated equipment. Currently, the main function of maintenance manholes on the top of the water tank is to provide access for maintenance, and their structural design usually does not consider integrating monitoring equipment on their top cover. Existing manhole structures generally suffer from insufficient load-bearing capacity and poor thermal insulation, failing to provide a stable, energy-efficient, and reliable installation platform for intelligent monitoring equipment.

[0003] 2. Fixed depth-direction temperature measurement points, resulting in poor flexibility. Traditional temperature measurement schemes often use pre-embedded temperature sensors at fixed depths. Once installed, the position and interval of the measurement points cannot be adjusted, making it difficult to adapt to different research priorities or operating conditions. When it is necessary to change the measurement depth interval, the sensors must be re-deployed, which is cumbersome, costly, and lacks flexibility.

[0004] 3. The monitoring system has a low level of intelligence and relies on wired power supply and transmission. Most existing temperature measurement systems require external power supply and wired data transmission. For large-area water tanks, wiring is complex, costly, and prone to damage, making maintenance difficult. The system lacks an intelligent solution that integrates power supply, data acquisition, wireless transmission, and remote monitoring, making it difficult to achieve real-time online monitoring and processing of data.

[0005] 4. Equipment installation damages the insulation structure, leading to additional heat loss. Traditional installation methods often require perforating or grooving the insulation layer when installing the monitoring device on the insulated top cover. This severely compromises the integrity of the top cover's insulation, creating thermal bridges and causing a significant loss of heat from the heat storage body, thus reducing system efficiency.

[0006] 5. Underwater sensors are unstable and difficult to deploy, retrieve, and maintain. Temperature sensors deployed in deep water are prone to swaying or displacement when disturbed by water flow or convection, leading to distorted measurement data. Furthermore, the lack of a device that can easily stabilize the sensor at a specified depth and facilitate convenient deployment, retrieval, calibration, replacement, or maintenance greatly complicates subsequent maintenance.

[0007] In summary, existing technologies lack a comprehensive solution that can simultaneously address numerous issues such as load-bearing capacity, thermal insulation, flexible temperature measurement, intelligent integration, stable fixation, and convenient maintenance. This has become a key technical bottleneck restricting the further refined operation and promotion of large-capacity deep-water thermal storage technology. Summary of the Invention

[0008] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a temperature measurement and maintenance device and its working method suitable for large-scale hot water storage bodies.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides an intelligent temperature measurement and maintenance device suitable for large-scale hot water storage bodies, including a water storage tank, an insulated top cover covering the top of the water storage tank, a maintenance well opened on the insulated top cover, an intelligent temperature measurement well cover installed at the top opening of the maintenance well, a temperature measurement component installed through the intelligent temperature measurement well cover, the temperature measurement component including a measuring rope, the measuring rope extending to the bottom of the water storage tank, a plurality of temperature measuring thermal resistors installed along the extension direction of the measuring rope, and a sinker set at the end of the measuring rope; The temperature measurement and maintenance device integrates an intelligent monitoring system to power the entire device and realize data acquisition and remote transmission. The intelligent monitoring system is detachably installed on the top of the intelligent temperature measurement manhole cover and includes a photovoltaic panel, a battery, a data acquisition and wireless transmission device, and a remote data receiving and processing module. The photovoltaic panel is electrically connected to the battery, which powers the data acquisition and wireless transmission device. The data acquisition and wireless transmission device is electrically connected to all temperature measuring resistance thermometers. The data acquisition and wireless transmission device wirelessly transmits the collected temperature data to the remote data receiving and processing module with a receiving antenna through its transmitting antenna.

[0010] The upper end of the measuring rope is connected to a lifting mechanism, which is used to raise and lower the measuring rope. The lifting mechanism includes a manual winch and a guide pulley. The manual winch is fixedly installed on the top of the smart temperature measuring well cover, and the measuring rope passes around the guide pulley and is guided and connected to the manual winch.

[0011] The measuring rope is equipped with size scale markings, and the temperature measuring resistance is fixed to the measuring rope by a fixing clamp.

[0012] The intelligent temperature measuring manhole cover has a handle at one end and a rotating shaft hinged to the opening of the maintenance manhole at the other end.

[0013] The intelligent temperature measuring manhole cover has an inspection port at its inner center, and a buoyancy ring is provided around the inspection port and its bottom. The buoyancy ring is fixed to the inner wall of the manhole by connecting bolts, which are evenly distributed along the circumference.

[0014] The maintenance well includes a top plate and a bottom plate, with several supporting frames installed between the top plate and the bottom plate, and insulation material filling the space between the top plate and the bottom plate.

[0015] The top plate and bottom plate are edge-sealed by an edge-sealing frame, and the edge-sealing frame is fixed to the top plate and bottom plate by connecting bolts.

[0016] The inner side of the water storage tank is covered with a heat insulation layer.

[0017] The insulation layer of the pool wall is made of polyurethane or XPS material.

[0018] Secondly, the present invention provides a working method for a temperature measurement and maintenance device suitable for large-scale hot water storage tanks, wherein a measuring rope is extended to the bottom of the water storage tank, and several temperature measuring resistance thermometers on the measuring rope measure the water temperature at different locations inside the water storage tank, and a data acquisition and wireless transmission device collects the measured temperature data and sends it to a remote data receiving and processing module. When it is necessary to calibrate the accuracy of the temperature measuring RTD, adjust the installation spacing in the depth direction, or replace a suspected faulty RTD, open the smart temperature measuring well cover, operate the lifting mechanism installed on the top of the well cover, and lift the measuring rope together with all the temperature measuring RTDs on it and the sinker at the bottom from the water. The operator can then check, calibrate, adjust or replace each temperature measuring element at the wellhead.

[0019] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a temperature measurement and maintenance device and its operating method suitable for large-scale hot water storage bodies. Multiple temperature-measuring resistance thermometers are precisely fixed at different depths using a vertically arranged, graduated measuring rope, enabling the simultaneous acquisition of continuous temperature profile data from the water surface to the bottom of the tank. This provides crucial scientific basis for analyzing the thermal stratification stability of the thermal storage body, calculating the effective heat storage capacity, and evaluating its insulation performance. The integrated intelligent monitoring system transmits data to a remote monitoring center in real time via wireless transmission technology, achieving unattended continuous monitoring. Maintenance personnel can monitor the water temperature anytime, anywhere, significantly reducing the labor intensity and cost of manual inspections.

[0020] Furthermore, when it is necessary to inspect or calibrate the temperature sensing element, operators do not need to empty the tens of thousands of tons of water storage tank. They can simply operate a manual winch at the wellhead to easily lift the entire temperature sensing component out of the water. This makes maintenance work very simple, fast, and safe, greatly reducing downtime.

[0021] Furthermore, this device uses photovoltaic solar panels and batteries for power supply, and wireless transmission with the receiver, eliminating the need for external power supply and signal wiring, thus saving on the material and installation costs of power supply and communication cables.

[0035] Preferably, the measuring rope 51 is equipped with size scale markings, and the temperature measuring resistor 52 is fixed to the measuring rope 51 by a fixing clip 54. Depending on the depth of the water storage tank 1 to be measured and the measurement interval, the temperature measuring resistor is fixed at a set depth position, and the sinker 53 and the temperature measuring resistor 52 are placed using a manual winch 61. The sinker 53 contacts the bottom of the tank, and the measuring rope 51 is tightened, completing the placement.

[0036] Preferably, one end of the intelligent temperature-measuring manhole cover 4 is provided with a handle 13, and the other end is hinged to a rotating shaft 14 at the connection point with the opening of the inspection well 3. Figure 4 As shown, an inspection port 41 is opened at the center of the inner side of the intelligent temperature measuring manhole cover 4. This opening is a passage for personnel or equipment to enter the manhole 3. A buoyancy ring 42 is set around the inspection port 41 and its bottom. The buoyancy ring 42 is fixed to the inner wall of the manhole 3 by connecting bolts 36, which are evenly distributed along the circumference. The inner diameter D1 of the inspection port 41 is 400~600mm, and the diameter D2 of the bottom buoyancy ring 42 can be selected according to the weight of the manhole 3 and the upper intelligent temperature measuring manhole cover 4.

[0037] Furthermore, the inspection well 3 includes a top plate 31 and a bottom plate 32, with several supporting frames 33 arranged between the top plate 31 and the bottom plate 32, and insulation material 34 filling the space between the top plate 31 and the bottom plate 32. The top plate 31 and the bottom plate 32 are sealed by edge-sealing frames 35, and the edge-sealing frames 35 are fixed to the top plate 31 and the bottom plate 32 by connecting bolts 36.

[0038] Preferably, the top plate 31, bottom plate 32, edge sealing frame 35, support frame 33, and connecting bolts 36 are made of FRP material, which is lightweight and has a certain mechanical strength.

[0039] Preferably, a pool wall insulation layer 15 is attached to the inner side of the water storage tank 1.

[0040] Preferably, such as Figures 5-6 As shown, the intelligent monitoring system is integrated in the equipment compartment 16. The equipment compartment 16 includes a manual winch 61, a battery compartment 17, and a data acquisition and wireless transmission equipment compartment 18. The battery 8 is placed in the battery compartment 17, and the data acquisition and wireless transmission equipment 9 is placed in the data acquisition and wireless transmission equipment compartment 18.

[0041] Preferably, the intelligent temperature measuring well cover 4 has an internal heat-insulating sealing ring 19. The heat-insulating material is polyurethane or XPS, which has the advantages of low thermal conductivity, low water absorption, and low density.

[0042] Example 2 A temperature measurement and maintenance device suitable for large hot water storage bodies, the working method of which is as follows: The upper end of the measuring rope 51 is looped around the guide pulley 62 and then fixed to the drum of the hand-cranked winch 61. By cranking the handle of the hand-cranked winch 61, the temperature measuring component 5 is steadily lowered into the water storage tank 1. The operator can know the depth of the sinking block 53 in real time and accurately by observing the size scale markings on the measuring rope 51. When the sinking block 53 descends to a certain safe distance from the bottom of the tank, such as 0.5 or a predetermined depth, the lowering is stopped. At this time, each temperature measuring resistor 52 is at its preset precise depth.

[0043] The device enters automatic operation mode. During the day, the photovoltaic panel 7 converts solar energy into electrical energy, which is stored in the battery 8, providing green power for the entire system around the clock. The data acquisition and wireless transmission device 9 automatically wakes up at preset time intervals and synchronously acquires the temperature values ​​measured by all thermistors 52 through its internal digital conversion channel. After the acquisition is completed, the data acquisition and wireless transmission device 9 packages the temperature data, device number, timestamp, and other information, and wirelessly transmits it to the remote data receiving and processing module 10 with receiving antenna 12 via its transmitting antenna 11 using the NB-IoT network.

[0044] Furthermore, when the accuracy of the temperature measuring resistors 52 needs to be calibrated, the installation spacing in the depth direction needs to be adjusted, or a resistor is suspected of being faulty and needs to be replaced, maintenance personnel do not need to empty the huge water tank. Upon arrival at the site, personnel open the intelligent temperature measuring well cover 4 by pulling the handle 13 around the rotating shaft 14; operate the lifting mechanism 6 installed on top of the well cover, crank the handle of the manual winch 61, and, guided by the guide pulley 62, lift the measuring rope 51 along with all the temperature measuring resistors 52 and the bottom sinker 53 from the water until they are all exposed at the inspection well opening. Operators can then conveniently inspect, calibrate, or replace each temperature measuring element at the well opening. The scale markings on the measuring rope also help to quickly locate elements at specific depths.

[0045] Furthermore, if a more in-depth inspection of the pool or maintenance of other equipment is required, personnel can enter the bottom of the maintenance well 3 through the inspection port 41 inside the intelligent temperature measuring well cover for inspection.

[0046] Furthermore, this device is not only suitable for hot water storage, but also for cold water storage, as well as other water bodies that require real-time temperature measurement.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention.
