Description

Technical Field

[0001] The present application relates to the technical field of heating systems, and more specifically, to a monitoring and alarm device for heating systems. Background Art

[0002] A heating system is a comprehensive system used to provide heat within a building to maintain a comfortable indoor temperature. This system consists of several components, one of which is the pipes that carry the heat medium (such as hot water, steam, or air) from the heat source to the rooms within the building. Pipes are a key component of the heating system, as they form the pathway for heat transfer.

[0003] Most of the existing heating systems are composed of multiple pipes, and one end of two adjacent pipes is butt-jointed using a connector. After long-term use, the connector is prone to water leakage due to aging. Existing monitoring alarms for leakage use water immersion sensors to detect whether there is water accumulation on the ground to determine whether the pipe is burst, or use water pressure sensors to sense sudden changes in water pressure in the pipe to determine a burst. The former requires that the water accumulates to a certain level before the water immersion sensor triggers an alarm, and the latter is insensitive to long-term, small-flow water leakage, resulting in delayed response, and is unable to quickly alarm for water pipe leakage, prolonging the potential damage caused by the leakage. Utility Model Content

[0005] The present application provides a heating system monitoring and alarm device that adopts the following technical solution:

[0009] Furthermore, the interior of the connection box is slidably connected to the moving box, the bottom of the moving box is fixedly connected to two first telescopic rods, and the exterior of the first telescopic rods is sleeved with two springs.

[0010] Furthermore, the top and bottom of the two first telescopic rods and the spring are fixedly connected to the moving box and the connecting box, and the bottom of the moving box is connected to a water outlet pipe.

[0012] Furthermore, a solenoid valve is provided at one end of the water outlet pipe, and a controller is provided inside the connecting ring.

[0013] Through the above technical solution, when the pressure sensor detects that there is too much liquid inside the moving box, the controller will open the solenoid valve inside the water outlet pipe to discharge the liquid inside the moving box to prevent the liquid inside the moving box 7 from overflowing.

[0014] Furthermore, two delivery pipes are provided inside the connecting ring, and the two delivery pipes are connected by fixing bolts.

[0015] Furthermore, the connecting ring is composed of two semicircular rings, both ends of the two semicircular rings are fixedly connected to the connecting blocks, the interiors of each of the two connecting blocks are threadedly connected with connecting bolts, and the two semicircular rings are connected by two connecting bolts.

[0016] Through the above technical solution, the connecting bolts can facilitate the disassembly and installation of the connecting ring 1.

[0017] Furthermore, an alarm is provided on the outside of the connection box, and one end of the water outlet pipe extends through and extends to the outside of the connection box in a sliding connection.

[0018] Furthermore, the controller is electrically connected to the pressure sensor, the alarm and the solenoid valve.

[0019] Through the above technical solution, the pressure sensor monitors, and when abnormal pressure is detected, the controller sends a signal to the alarm to alert the staff to handle it.

[0022] (2) The controller of the utility model can set different alarm levels according to the size of the received pressure signal. For example, when there is a slight leak, the pressure sensor on one side of the sensing plate will feel a small pressure, and the controller will send a low-level alarm signal to the alarm, triggering a low-volume sound; when the pressure sensor senses an increase in pressure, it will send a high-level alarm signal, triggering a higher-volume sound, so as to quickly understand the severity of the current leak;

[0023] (3) The utility model can monitor and alarm the severity of leakage by setting different alarm levels according to the size of the pressure signal, so that the operator can judge the leakage situation according to the size and frequency of the alarm sound, and thus take corresponding countermeasures more accurately.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0031] Reference Figure 1-Figure 5 , a heating system monitoring alarm device, comprising a connecting ring 1, a connecting box 5 is connected to the bottom of the connecting ring 1, and an alarm component is arranged inside the connecting box 5;

[0032] The alarm component includes a second telescopic rod 12, the bottom of the second telescopic rod 12 is fixedly connected to an extrusion block 13, the inside of the connecting box 5 is fixedly connected to a sensing plate 11, one side of the sensing plate 11 is fixedly connected to a pressure sensor 14, and the extrusion block 13 is located above the sensing plate 11.

[0033] By setting the alarm component, when a leak occurs in the delivery pipe 2 in the heating system, an alarm can be given in time, which facilitates timely maintenance of the connection between the two delivery pipes 2, reduces the impact on the heating effect, and reduces the losses caused by leakage.

[0034] Reference Figure 3-Figure 4 The connecting box 5 is internally slidably connected to a moving box 7, the bottom of the moving box 7 is fixedly connected to two first telescopic rods 8, the outside of the first telescopic rods 8 is sleeved with two springs 9, the tops and bottoms of the two first telescopic rods 8 and the springs 9 are fixedly connected to the moving box 7 and the connecting box 5, and the bottom of the moving box 7 is connected to a water outlet pipe 10.

[0035] When a leak occurs at the connection between the two heating system delivery pipes 2, hot water will flow out from the two delivery pipes 2 and flow into the inside of the mobile box 7. When the hot water enters the inside of the mobile box 7, the hot water will increase the weight of the mobile box 7, thereby causing the mobile box 7 to move downward. At this time, the first telescopic rod 8 and the spring 9 at the bottom of the mobile box 7 will shrink, and the second telescopic rod 12 at the bottom of the mobile box 7 will also shrink, exerting a certain force downward. At this time, the extrusion block 13 is in contact with the induction plate 11, and the pressure sensor 14 senses the pressure. The pressure sensor 14 senses this pressure change and transmits a signal to the controller. The controller determines the degree of leakage based on the preset pressure threshold.

[0036] The controller can set different alarm levels according to the size of the received pressure signal. For example, when there is a slight leak, the pressure sensor 14 on one side of the sensing plate 11 will feel a small pressure, and the controller will send a low-level alarm signal to the alarm 15, triggering a low-volume sound; when the pressure sensor 14 senses an increase in pressure, it will send a high-level alarm signal, triggering a higher-volume sound.

[0037] By setting different alarm levels according to the size of the pressure signal, the severity of the leak can be monitored and an alarm can be given. In this way, operators can judge the leak situation based on the size and frequency of the alarm sound, and take corresponding countermeasures more accurately.

[0038] When the pressure sensor 14 detects that there is too much liquid in the moving box 7 , the controller will open the solenoid valve 16 in the water outlet pipe 10 to discharge the liquid in the moving box 7 to prevent the liquid in the moving box 7 from overflowing.

[0039] Reference Figure 1-Figure 2 Two conveying pipes 2 are arranged inside the connecting ring 1, and the two conveying pipes 2 are connected by fixing bolts 6. The connecting ring 1 is composed of two semicircular rings, and both ends of the two semicircular rings are fixedly connected to the connecting blocks 3. The interiors of each two connecting blocks 3 are threadedly connected with connecting bolts 4, and the two semicircular rings are connected by two connecting bolts 4.

[0040] The connection bolts 4 are provided to facilitate disassembly and installation of the connection ring 1 .

[0041] Reference Figure 1-Figure 5 A solenoid valve 16 is provided at one end of the water outlet pipe 10, a controller is provided inside the connecting ring 1, an alarm 15 is provided outside the connecting box 5, one end of the water outlet pipe 10 extends through and extends to the outside of the connecting box 5 in a sliding connection, the controller is electrically connected to the pressure sensor 14, the alarm 15 and the solenoid valve 16, and the model of the pressure sensor 14 is Bosch SensortecBMP180.

[0042] The pressure sensor 14 monitors and when an abnormal pressure is detected, the controller sends a signal to the alarm 15 to sound an alarm, so as to remind the staff to handle the situation.

[0043] Working principle: When there is a leak at the connection of the two heating system delivery pipes 2, hot water will flow out from the two delivery pipes 2 and flow into the inside of the mobile box 7. When the hot water enters the inside of the mobile box 7, the hot water will increase the weight of the mobile box 7, thereby causing the mobile box 7 to move downward. At this time, the first telescopic rod 8 and the spring 9 at the bottom of the mobile box 7 will shrink, and the second telescopic rod 12 at the bottom of the mobile box 7 will also shrink, exerting a certain force downward. At this time, the extrusion block 13 contacts the induction plate 11, and the pressure sensor 14 feels the pressure. The pressure sensor 14 senses this pressure change and transmits a signal to the controller. The controller determines the degree of leakage according to the preset pressure threshold. The controller can set different alarm levels according to the size of the received pressure signal. For example, when there is a slight leak, the pressure sensor 14 on one side of the induction plate 11 will feel a small pressure, and the controller will send a low-level alarm signal to the alarm 15, triggering a low-volume sound; when the pressure sensor 14 senses an increase in pressure, it will send a high-level alarm signal, triggering a higher-volume sound, reminding the staff to handle it.
