Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat theft prevention technology, specifically to a passive heat theft prevention device based on the Internet of Things. Background Technology
[0002] In the operation and management of centralized heating systems, heat theft has become a persistent problem hindering the healthy development of the industry. It not only seriously damages the economic benefits of heating companies and causes a large amount of heat revenue to be lost, but also disrupts the hydraulic balance of the heating system and affects the heating quality of other normal users.
[0003] Currently, to prevent heat theft, heating companies typically lock the outside of heating valves to prevent thieves from illegally opening them. However, these locks are often easily damaged, requiring regular inspections by staff. Due to the wide coverage of the heating network and the large number of users, manual inspections often take several days or even weeks to complete a full inspection. As a result, it is impossible to detect heat theft immediately when thieves illegally open the heating valves. This means that heat theft occurring during the inspection intervals cannot be detected in time, leading to continuous heat loss. Utility Model Content
[0004] In view of the problems existing in the above-mentioned anti-heat theft devices, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a passive heat theft prevention device based on the Internet of Things, which solves the problem that existing heat theft prevention devices are easily opened by heat thieves and cannot detect heat theft behavior in the first instance, resulting in continuous heat loss before the behavior is discovered.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] The IoT-based passive heat theft prevention device includes a heating pipe with a valve at its top. A protective cover is installed on the outer surface of the valve, and a mounting base is located below the protective cover. Two L-shaped grooves are formed on one side of the mounting base, and L-shaped plates are slidably installed inside each groove. The two L-shaped plates are fixedly connected to the lower surfaces of the protective cover on both sides. A sliding groove is formed on the upper surface of each L-shaped groove, and a fixing mechanism is installed inside each groove. The two L-shaped plates are fixed by their respective fixing mechanisms. A cavity is formed below the mounting base, and a pressure sensor is fixedly connected inside the cavity. A through hole is formed on the upper surface of the cavity, and an upper pressure block and a lower pressure block are slidably installed inside the through hole. A spring is fixedly connected between the upper and lower pressure blocks.
[0008] Preferably, the fixing mechanism includes two lead screws, two inserts, and two knobs. The two lead screws are rotatably connected to the upper surface inside the corresponding slide groove, and the two inserts are threaded onto the outer surface of the corresponding lead screw. The upper surface of the fixing seat has two deep grooves. The upper ends of the two lead screws pass through the upper surface inside the corresponding slide groove and extend into the interior of the corresponding deep groove. The two knobs are respectively disposed inside the corresponding deep groove and are fixedly connected to the upper ends of the corresponding lead screws.
[0009] Preferably, the inner walls of the two sliding grooves are provided with corresponding first limiting grooves, and a first limiting block is slidably disposed inside each first limiting groove, and each first limiting block is fixedly connected to the outer surface of the corresponding insert.
[0010] Preferably, the through hole is provided with symmetrical second limiting grooves, and each of the two second limiting grooves is provided with a second limiting block, which is symmetrically and fixedly connected to both sides of the upper pressure block.
[0011] Preferably, one side of each of the two knobs has an irregularly shaped groove.
[0012] Preferably, the upper surfaces of the two L-shaped plates are provided with slots, and the two slots are respectively matched with corresponding inserts.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] 1. This utility model prevents unauthorized opening through a protective cover, while a pressure sensor monitors the pressure changes between the fixed base and the heating pipe in real time. When a heat thief disassembles the device, the spring rebounds, causing a sudden pressure change. The sensor sends an alarm to the monitoring system in real time via the Internet of Things, solving the problem of lag in traditional manual inspections, realizing immediate early warning of heat theft, and reducing heat loss.
[0015] 2. This utility model securely locks the protective cover onto the fixed base through the threaded transmission of the lead screw and the insert block. The first limiting block and the limiting groove ensure that the insert block moves linearly and avoids deviation. The knob adopts an irregular groove design, which requires special tools to operate and increases the difficulty of disassembly. The deep groove hidden installation further prevents human touch. The multi-structure design significantly improves the anti-vandalism capability. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] This utility model discloses a passive heat theft prevention device based on the Internet of Things.
[0024] This utility model provides, for example Figure 1-3 The passive anti-theft heat device based on the Internet of Things shown includes a heating pipe 1, a valve 2 installed above the heating pipe 1, a protective cover 3 installed on the outer surface of the valve 2, a fixing seat 4 installed below the protective cover 3, two L-shaped grooves opened on one side of the fixing seat 4, and L-shaped plates 5 slidably installed inside the two L-shaped grooves. The two L-shaped plates 5 are respectively fixedly connected to the lower surfaces of the two sides of the protective cover 3. The upper surfaces of the two L-shaped grooves are provided with sliding grooves, and fixing mechanisms are provided inside the two sliding grooves. The two L-shaped plates 5 are respectively fixed by corresponding fixing mechanisms. A cavity is opened below the fixing seat 4, and a pressure sensor 6 is fixedly connected inside the cavity. A through hole is opened on the upper surface of the cavity, and an upper pressure block 7 and a lower pressure block 8 are slidably installed inside the through hole. A spring 9 is fixedly connected between the upper pressure block 7 and the lower pressure block 8.
[0025] During installation, the protective cover 3 is first placed on the outer surface of the valve 2, and then the fixing seat 4 is attached to the lower surface of the heating pipe 1. The fixing seat 4 is then slid, and the two L-shaped plates 5 are slid into the corresponding L-shaped grooves. At this time, the protective cover 3 can prevent the valve 2 from being opened illegally. When the fixing seat 4 is attached to the heating pipe 1, the upper pressure block 7 squeezes the spring 9, and then the lower pressure block 8 applies pressure to the pressure sensor 6. The pressure sensor 6 records the initial pressure value. When the heat thief disassembles the device, the spring 9 rebounds, thereby changing the pressure on the surface of the pressure sensor 6. The sensor detects the sudden change in pressure and then sends a signal to the monitoring system so that the staff can detect the abnormality as soon as possible.
[0026] In order for the mounting bracket 4 to be fixed, such as Figure 1-3 As shown, the fixing mechanism includes two lead screws 10, two inserts 12, and two knobs 13. The two lead screws 10 are rotatably connected to the upper surface of the corresponding slide groove, and the two inserts 12 are threaded onto the outer surface of the corresponding lead screw 10. The upper surface of the fixing seat 4 has two deep grooves. The upper ends of the two lead screws 10 pass through the upper surface of the corresponding slide groove and extend into the interior of the corresponding deep groove. The two knobs 13 are respectively located in the interior of the corresponding deep groove and are fixedly connected to the upper ends of the corresponding lead screws 10. The upper surfaces of the two L-shaped plates 5 are each provided with slots, and the two slots are respectively matched with the corresponding inserts 12.
[0027] The protective cover 3 is inserted into the L-shaped groove of the fixing seat 4 through the L-shaped plates 5 on both sides to form the initial installation position. Turning the knob 13 drives the lead screw 10 to rotate, and the threaded insert 12 moves down along the slide groove and inserts into the slot of the L-shaped plate 5, firmly locking the protective cover 3 on the fixing seat 4.
[0028] In order for the insertion block 12 to rotate, as Figure 2 As shown, the inner walls of the two slides are provided with first limiting grooves, and each first limiting groove is slidably provided with a first limiting block 14. Each first limiting block 14 is fixedly connected to the outer surface of the corresponding insert block 12.
[0029] The cooperation between the first limiting block 14 and the first limiting groove ensures that the insert block 12 moves in a straight line and avoids deviation.
[0030] To prevent the upper pressure block 7 from moving out of the through hole, such as Figure 2 As shown, the inside of the through hole is symmetrically provided with second limiting grooves, and the inside of each of the two second limiting grooves is slidably provided with a second limiting block 11. The two second limiting blocks 11 are symmetrically fixedly connected to both sides of the upper pressure block 7.
[0031] The two second limiting blocks 11 can be used to limit the movement, thereby preventing the upper pressure block 7 from moving out of the through hole.
[0032] To prevent the device from becoming more effective at providing protection, such as Figure 1-3 As shown, each of the two knobs 13 has a shaped groove on one side.
[0033] The irregular groove design of knob 13 requires special tools to operate, making it difficult for ordinary users to disassemble and increasing the difficulty of destruction. At the same time, placing knob 13 in a deep groove also prevents it from being touched by heat thieves.
[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
