Technical Field
[0001] This utility model relates to the field of monitoring and alarm equipment technology, and in particular to a real-time monitoring and alarm device for the temperature and pressure of circulating cooling water in a medium-frequency furnace. Background Technology
[0002] In industrial production, the stable operation of the cooling water circulation system is crucial for intermediate frequency furnaces, which are key pieces of equipment. For example, in the case of a thyristor parallel inverter power supply system for an intermediate frequency melting furnace, abnormal water temperature or pressure in the cooling water circulation system can affect the power system's energy efficiency and may even cause malfunctions due to poor heat dissipation of components such as the thyristors, thus disrupting production schedules and increasing costs. Currently, the sensors used to monitor the water temperature and pressure of this system are generally installed using flanges with multiple sets of bolts. This installation method presents many inconveniences in actual operation. Each time maintenance or sensor replacement is performed, a significant amount of time is required to disassemble and install the bolts, which is not only cumbersome but also greatly increases the workload of maintenance personnel and reduces maintenance efficiency. Utility Model Content
[0003] The technical problem to be solved by this utility model is that the existing technology requires a lot of time to disassemble and install bolts every time the sensor is maintained or replaced. This is not only cumbersome, but also greatly increases the workload of maintenance personnel and reduces maintenance efficiency. To address this, we propose a real-time monitoring and alarm device for the temperature and pressure of the cooling water circulation in a medium-frequency furnace.
[0004] To achieve the above objectives, this application adopts the following technical solution: a real-time monitoring and alarm device for the temperature and pressure of circulating cooling water in a medium-frequency furnace, comprising a cooling water pipe and an installation body for connecting the cooling water pipe. A sensing body is installed at the upper end of the installation body, and the sensing body is electrically connected to a safety monitoring and control box. An audible and visual alarm body is installed on the outer wall of the safety monitoring and control box. An upper mounting plate is fixedly connected to the lower wall of the sensing body, and a lower mounting plate is fixedly connected to the upper wall of the installation body. The inner wall of the lower mounting plate has a locking groove and an installation groove. A locking block is fixedly connected to the lower end of the upper mounting plate, and an installation block is fixedly connected to the inner wall of the locking block. The installation block is threadedly connected to the installation groove. An opening is opened on the lower wall of the installation block, and an adsorption magnetic block A is fixedly connected to the inner cavity of the opening. An adsorption magnetic block B is fixedly connected to the bottom of the installation groove. The adsorption magnetic block A and the adsorption magnetic block B are attracted to each other by opposite polarities.
[0005] Furthermore, a lower connecting groove is provided at the bottom of the mounting groove, and a sliding block is slidably connected to the inner wall of the lower connecting groove. The upper end of the sliding block is fixedly connected to the adsorption magnetic block B, and a return spring is fixedly connected to the end of the sliding block away from the adsorption magnetic block B. The bottom of the return spring is fixedly connected to the bottom of the cavity of the lower connecting groove.
[0006] Furthermore, one side of the lower receiving groove is connected to a movable channel, and the end of the movable channel away from the lower receiving groove penetrates the outer wall of the lower loading tray.
[0007] Furthermore, a top rod body is slidably connected to the inner wall of the active channel, and a threaded inner rod is threadedly connected to the inner wall of the top rod body. A control block is fixedly connected to the end of the threaded inner rod away from the top rod body, and the control block is rotatably connected to the outer wall of the lower loading plate.
[0008] Furthermore, the upper wall of the top rod body near the lower groove has an arc-shaped structure to assist the upper sliding block.
[0009] Furthermore, when the reset spring is relaxed, the magnetic block B is located inside the cavity of the lower groove; when the reset spring is tightened, the magnetic block B protrudes from the opening of the lower groove.
[0010] The technical effects and advantages of this utility model are as follows: In this invention, during disassembly and maintenance, the power is first disconnected and the wires are unplugged. The control block is rotated counterclockwise to rotate the threaded inner rod, causing the top rod body to move along the movable channel away from the lower groove and disengage from the bottom support of the sliding block. Then, the reset spring releases the reset force, pulling the sliding block and the adsorption magnetic block B downward to reset, weakening the attraction with the adsorption magnetic block A. At this point, the sensor body can be removed by rotating counterclockwise again. If the attraction is still not completely eliminated, the sliding block can be forcibly separated by pushing the top rod body. No bolts need to be removed throughout the process, which greatly improves maintenance efficiency and solves the problem that every time maintenance or sensor replacement is performed, a lot of time needs to be spent removing and installing bolts, which is not only cumbersome but also greatly increases the workload of maintenance personnel and reduces maintenance efficiency.

[0013] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0014] Reference Figures 1-4 As shown, to address the issue that each maintenance or sensor replacement requires a significant amount of time to disassemble and install bolts, which is not only cumbersome but also greatly increases the workload of maintenance personnel and reduces maintenance efficiency, the following preferred technical solutions are provided: A real-time monitoring and alarm device for the temperature and pressure of circulating cooling water in a medium-frequency furnace includes a cooling water pipe 1 and an installation body 2 for connecting the cooling water pipe 1. The device uses the cooling water pipe 1 as the monitoring carrier and the installation body 2 for connecting the cooling water pipe 1 as the core support. A sensing body 3 installed on the upper end of the installation body 2 is responsible for collecting water temperature and pressure data in real time. The sensing body 3 is electrically connected to a safety monitoring and control box 4, which can receive and process data and issue early warnings through an external audible and visual alarm body. The lower wall of the sensing body 3 is fixedly connected to an upper mounting plate 5, and the upper wall of the installation body 2 is fixedly connected to a lower mounting plate 6. The upper mounting plate 5 and the lower mounting plate 6 are detachably connected through a snap-fit, threaded, and magnetic structure. The upper mounting plate 5 moves synchronously with the sensing body 3, and the lower mounting plate 6 is fixed on the installation body 2 to provide a stable docking reference. The fit between the two directly affects the connection sealing and sensing stability. The lower loading plate 6 has a locking groove 7 and a mounting groove 8 on its inner wall. The lower end of the upper loading plate 5 is fixedly connected to a locking block 9, and the inner wall of the locking block 9 is fixedly connected to a mounting block 10. The locking block 9 is adapted to the locking groove 7, and the mounting block 10 is threadedly connected to the mounting groove 8. During installation, the locking block 9 is first inserted into the locking groove 7 for initial positioning, and then the sensor body 3 is rotated to drive the mounting block 10 into the mounting groove 8 for fixation. During disassembly, the mounting block 10 can be disengaged from the mounting groove 8 by rotating in the opposite direction. The lower wall of the mounting block 10 has an opening 11, and the inner cavity of the opening 11 is fixedly connected to an adsorption magnetic block A12. The bottom of the mounting groove 8 is fixedly connected to an adsorption magnetic block B13, and the adsorption magnetic blocks A12 and B13 are attracted by opposite poles. When the mounting block 10 is screwed into the mounting groove 8, the adsorption magnetic blocks A12 and B13 attract each other, and the resulting magnetic attraction tightly fits the upper loading plate 5 and the lower loading plate 6, while the threaded structure helps resist vibration and loosening. The bottom of the mounting groove 8 has a lower receiving groove 14. A sliding block 15 is slidably connected to the inner wall of the lower receiving groove 14. The upper end of the sliding block 15 is fixedly connected to the magnetic adsorption block B13. A return spring 16 is fixedly connected to the end of the sliding block 15 away from the magnetic adsorption block B13. The bottom of the return spring 16 is fixedly connected to the bottom of the cavity of the lower receiving groove 14. When the return spring 16 is relaxed, the magnetic adsorption block B13 is completely inside the cavity of the lower receiving groove 14 and does not protrude from the opening. When the magnetic adsorption block B13 and the magnetic adsorption block A12 are attracted by opposite poles, the sliding block 15 will slide upward along the lower receiving groove 14, and the return spring 16 will be tightened simultaneously. At this time, the magnetic adsorption block B13 will protrude from the opening of the lower receiving groove 14 and be tightly attracted to the magnetic adsorption block A12. When disassembling, the automatic reset force of the return spring 16 will pull the sliding block 15 and the magnetic adsorption block B13 downward, assisting in separating the magnetic adsorption blocks A12 and B13.
[0015] A movable channel is connected to one side of the lower receiving groove 14. The end of the movable channel away from the lower receiving groove 14 passes through the outer wall of the lower loading plate 6. A push rod body 17 is slidably connected to the inner wall of the movable channel. A threaded inner rod 18 is threadedly connected to the inner wall of the push rod body 17. A control block 19 is fixedly connected to the end of the threaded inner rod 18 away from the push rod body 17. The control block 19 is rotatably connected to the outer wall of the lower loading plate 6, and the upper wall of the push rod body 17 near the lower receiving groove 14 has an arc-shaped structure. Rotating the control block 19 causes the threaded inner rod 18 to rotate, pushing the push rod body 17 to move along the movable channel towards the lower receiving groove 14. The arc-shaped upper wall of the push rod body 17 lifts the sliding block 15, and the sliding block 15 drives the adsorption magnetic block B13 to move upward, providing effective support for the adsorption magnetic block B13.
[0016] Specifically, the installation body 2, which connects to the cooling water pipe 1, serves as a support. The lower mounting plate 6 at its upper end forms a docking base with the upper mounting plate 5 on the lower wall of the sensing body 3. During installation, the locking block 9 of the upper mounting plate 5 is first inserted into the locking groove 7 of the lower mounting plate 6 for positioning. Then, the sensing body 3 is rotated so that the mounting block 10 inside the locking block 9 is screwed into the mounting groove 8 of the lower mounting plate 6 for fixation. At this time, the magnetic adsorption block A12 in the opening 11 of the mounting block 10 and the magnetic adsorption block B13 in the mounting groove 8 are attracted by opposite polarities. Under the action of attraction, the magnetic adsorption block B13 moves upward and protrudes out of the opening of the lower connecting groove 14. The sliding block 15 in the lower connecting groove 14 moves upward synchronously with the magnetic adsorption block B13 and tightens the return spring 16. The top rod body 17 is located on the lower wall of the sliding block 15 at this time, providing support for the magnetic adsorption block B13. The sensing body 3 is connected to the safety monitoring and control box 4 through wires, which can monitor the water temperature and water pressure in real time and issue warnings through the sound and light alarm body. During disassembly and maintenance, first disconnect the power and unplug the wires. Rotate the control block 19 counterclockwise to rotate the threaded inner rod 18, causing the top rod body 17 to move along the movable channel away from the lower receiving groove 14 and disengage from the bottom support of the sliding block 15. Then, the reset spring 16 releases the reset force, pulling the sliding block 15 and the adsorption magnetic block B13 downward to reset, weakening the attraction with the adsorption magnetic block A12. At this time, the sensor body 3 can be removed by rotating it counterclockwise. If the attraction is not completely eliminated, the sliding block 15 can be forcibly separated by pushing the top rod body 17. No bolts need to be removed throughout the process, which greatly improves the efficiency of operation and maintenance. It solves the problem that every time a maintenance or sensor replacement is performed, a lot of time needs to be spent removing and installing bolts, which is not only cumbersome but also greatly increases the workload of maintenance personnel and reduces maintenance efficiency.
[0017] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
