A Chinese patent with publication number CN116481604A discloses an antifreeze-type insulated water meter box, including a box body, a box door is movably installed at the front end of the box body through a hinge, two locking mechanisms are commonly arranged between the box body and the box door, a transparent plate is inlaid and installed in the middle of the front end of the box door, an insulation board is fixedly installed at the rear end of the box door, and a No. 1 heating plate is fixedly installed on the left and right sides of the rear end of the insulation board, a plurality of water meters are arranged in the box body, and water inlet pipes and water outlet pipes are respectively fixedly installed at the left and right ends of the plurality of water meters, and an insulation mechanism is commonly arranged on the water inlet pipe and the water outlet pipe, and a controller and a temperature sensor are fixedly installed on the left inner wall of the box body.

[0004] Antifreeze water meter boxes usually use heating components to heat the inside of the water meter box when the temperature is low to maintain the ideal temperature and prevent ice from forming inside the water meter box. However, during use, if there is a sealing problem with the door of the water meter box, gaps will appear in the contact area between the door and the water meter box, making it difficult to detect and find, and difficult to discover in time, resulting in unsatisfactory heating and subsequent freezing and damage to the water meter body. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a temperature monitoring sensor and a monitoring system for an antifreeze water meter box.

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: In a first aspect, a temperature monitoring sensor for an antifreeze water meter box is provided, comprising a first temperature sensor, a second temperature sensor and a water meter box, and further comprising: A water pipe, wherein the water pipe is fixedly connected to a water meter body, and the first temperature sensor is installed on the surface of the water pipe near the water meter body to monitor the water temperature in the pipe; A transmission belt is connected to the second temperature sensor via a connecting assembly, and the transmission belt is used to drive the second temperature sensor to move along the edge of the door gap of the water meter box to monitor the temperature at the door gap.

[0007] It should be understood that the temperature values ​​detected by the first temperature sensor and the second temperature sensor always remain in a non-ideal state, convection may be formed between the internal and external spaces of the water meter box, and there is a problem with the seal at the door opening of the water meter box. At this time, the transmission belt is started, and the transmission belt drives the second temperature sensor to move at the edge of the door opening of the water meter box through the connecting component. If the second temperature sensor detects a significant drop in temperature when it moves to a certain position, the staff is reminded to carry out maintenance based on this, which makes it convenient for the staff to find the sealing problem, thereby facilitating the timely resolution of the sealing problem, maintaining the antifreeze function of the water meter box, and further facilitating antifreeze protection of the water meter body.

[0008] As an optional embodiment of the present invention, the connection component includes: A movable track, wherein a synchronous plate is fixedly connected to the front end of the movable track end, and the bottom end of the synchronous plate is rotatably connected to the side edge of the transmission belt; A fixed track, the fixed track is fixedly mounted on the inner bottom surface of the water meter box; A docking socket, the docking socket is slidably installed in the fixed track, and a first magnetic attraction component is arranged between the docking socket and the fixed track, the first magnetic attraction component is used to position the docking socket on the fixed track, and a second magnetic attraction component is arranged between the docking socket and the movable track, after the first magnetic attraction component cancels the magnetic attraction positioning of the docking socket, the second magnetic attraction component is used to magnetically attract the docking socket and magnetically position the docking socket on the movable track.

[0009] It should be understood that when the temperature in the water meter box is kept at an ideal temperature, the docking seat will be positioned in the fixed track under the magnetic attraction of the first magnetic attraction component, and will be far away from the door gap of the water meter box and close to the water meter body, which is conducive to detecting the temperature around the water meter body and controlling the temperature around the water meter body; However, when the temperatures detected by the first temperature sensor and the second temperature sensor cannot reach the ideal value, it indicates that there may be air leakage inside the water meter box. After controlling the first magnetic attraction component to cancel the magnetic attraction positioning of the docking seat, the second magnetic attraction component is controlled to magnetically attract the docking seat, and the docking seat is magnetically positioned on the movable track, so as to prepare for the transmission belt to drive the second temperature sensor to move near the edge of the door gap of the water meter box; After the docking socket is docked onto the movable track, the transmission belt is started, and the transmission belt drives the second temperature sensor near the door gap of the water meter box to move along the track of the door gap of the water meter box, so as to evenly detect the vicinity of the door gap of the water meter box, which is beneficial to thoroughly detect the temperature at the door gap of the water meter box. If a significant drop in temperature value is detected at a certain position, it means that there may be a problem with the sealing at that position, and the staff may be prompted to perform maintenance in time, which is beneficial to timely solve the door sealing problem of the water meter box, and further helps to maintain good antifreeze protection for the water meter body.

[0010] As an optional embodiment of the present invention, a transmission assembly is connected between the transmission belt and the edge of the door opening of the water meter box, and the transmission assembly includes: An installation groove, the installation groove is provided at the edge of the door opening of the water meter box; Four motors, the four motors are fixedly mounted at the four corners of the mounting slot, and the output ends are fixedly connected with synchronous gears, and the surfaces of the four synchronous gears are synchronously connected with the transmission belt; A support groove is provided on the inner wall of the mounting groove, and a support pin is slidably installed in the support groove, and the support pin is rotatably connected to the synchronization plate.

[0011] As an optional embodiment of the present invention, the first magnetic attraction component includes: A first electromagnet, wherein the first electromagnet is fixedly mounted on the inner bottom surface of the water meter box; The first docking magnet is fixedly mounted on the back of the docking seat and is magnetically matched with the first electromagnet.

[0012] As an optional embodiment of the present invention, the second magnetic attraction component includes: A second electromagnet, wherein the second electromagnet is fixedly embedded on the back side of the synchronization plate; A second docking magnet is fixedly mounted on the front side of the docking seat.

[0013] As a further optimized embodiment of the present invention, it also includes: A limiting sleeve, the limiting sleeve is fixedly connected to the back side of the synchronization plate; The docking pin is fixedly connected to the front side of the docking seat and is sleeved on the surface of the second docking magnet. During the magnetic docking between the second docking magnet and the second electromagnet, the docking pin will be inserted into the limit sleeve and dock with the limit sleeve.

[0014] As a further optimized implementation of the present invention, a hot air blower is fixedly installed inside the water meter box, and an air outlet and an air inlet of the hot air blower are both arranged inside the water meter box.

[0015] As a specific implementation of the present invention, a sealing door is hinged at the door opening of the water meter box.

[0016] In a second aspect, a detection system is provided, including a temperature monitoring sensor for an antifreeze water meter box, and further comprising: A controller, wherein the controller is used to control the hot air blower to turn on when the first temperature sensor or the second temperature sensor detects that the temperature is close to zero degrees, so as to heat the interior of the water meter box until the first temperature sensor and the second temperature sensor detect an ideal temperature value; Among them, when the temperature detected by the first temperature sensor or the second temperature sensor still fails to reach an ideal value in the heating state, the first magnetic attraction component is controlled to cancel the magnetic attraction, and then the second magnetic attraction component is controlled to start the magnetic attraction, the docking seat is docked on the movable track, and then the transmission belt is controlled to drive the second temperature sensor on the docking seat to move at the edge of the door opening of the water meter body to monitor the temperature at the door gap of the water meter body.

[0017] Specifically, the controller is fixedly mounted on the surface of the water meter box; It should be understood that when the first temperature sensor or the second temperature sensor detects a temperature close to zero degrees, a request message is generated, requesting the controller to control the hot air blower to turn on to heat the interior of the water meter box until the first temperature sensor and the second temperature sensor detect an ideal temperature value.

[0018] In the heating state, when the temperature detected by the first temperature sensor or the second temperature sensor fails to reach the ideal value at multiple time points, a request message is generated, requesting the controller to control the first magnetic attraction component to cancel the magnetic attraction, and then control the second magnetic attraction component to start the magnetic attraction, dock the docking seat on the movable track, and then control the transmission belt to drive the second temperature sensor on the docking seat to move along the edge of the door opening of the water meter body to monitor the temperature at the door gap of the water meter body, thereby realizing automatic detection of the sealing condition of the door gap of the water meter box, which is convenient and fast, and is conducive to timely feedback of problems with the sealing of the water meter box, so that the staff can be informed in time and take maintenance measures.

[0019] As a further optimized embodiment of the present invention, it also includes A fixing seat, the fixing seat is fixedly connected to the top surface of the docking seat, and two connecting pins are fixedly connected to the surface, and the surface of the connecting pins is sleeved with a supporting spring; A mounting frame, the mounting frame is slidably plugged into the connecting pin, the mounting frame and the fixing seat are fixedly connected to the two ends of the supporting spring respectively, and the fan blades are rotatably connected to the mounting frame; A pressure sensor, the pressure sensor is fixedly mounted on the fixing seat, and a detection end is in contact with the surface of the mounting frame; A rotation speed sensor, wherein the rotation speed sensor is mounted on the rotating shaft of the fan blade to detect the rotation speed of the rotating shaft of the fan blade; The controller also determines whether there is air leakage at the door gap at the corresponding position of the water meter box according to the pressure value detected by the pressure sensor and the rotation speed value detected by the rotation speed sensor. It should be understood that if there is a problem with the seal, and convection is formed from the outside to the inside, the external airflow will cause the local temperature to drop, which will also affect the fan blades. The fan blades will rotate, and the speed sensor will capture the speed. At the same time, the force will act on the pressure sensor, causing the pressure detected by the pressure sensor to change. The speed detected by the speed sensor is significantly accelerated, and the pressure detected by the pressure sensor is significantly increased or decreased, which further provides the factors of air leakage in the door gap of the water meter box, which helps to provide further basis for the situation of air leakage; It should be further explained that the increase in the pressure value detected by the pressure sensor is because when the airflow flows into the water meter box, it will blow toward the front of the fan blades. At this time, the fan blades will rotate and push the entire mounting frame inward, which will squeeze the support spring and the pressure sensor at the same time, resulting in an increase in the pressure value, indicating that wind has entered; The pressure value detected by the pressure sensor decreases because the airflow is flowing to the outside of the water meter box, from the back of the fan blades. The fan blades will also rotate and simultaneously push the entire mounting frame outward, thereby releasing the extrusion pressure on the pressure sensor, resulting in a decrease in the pressure value, indicating that there is airflow flowing to the outside of the door gap.

[0020] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, a transmission belt drives the second temperature sensor near the door gap of the water meter box to move along the track of the door gap of the water meter box, so as to evenly detect the vicinity of the door gap of the water meter box, which is beneficial to thoroughly detect the temperature at the door gap of the water meter box. If a significant drop in the temperature value is detected at a certain position, it means that there may be a problem with the sealing of the position, and the staff is promptly prompted to perform maintenance, which is beneficial to timely solve the door sealing problem of the water meter box, and further beneficial to maintain good anti-freeze protection for the water meter body.

[0021] In the heating state, when the temperature detected by the first temperature sensor or the second temperature sensor fails to reach the ideal value at multiple time points, a request message is generated, requesting the controller to control the first magnetic attraction component to cancel the magnetic attraction, and then control the second magnetic attraction component to start the magnetic attraction, dock the docking seat on the movable track, and then control the transmission belt to drive the second temperature sensor on the docking seat to move along the edge of the door opening of the water meter body to monitor the temperature at the door gap of the water meter body, thereby realizing automatic detection of the sealing condition of the door gap of the water meter box, which is convenient and fast, and is conducive to timely feedback of problems with the sealing of the water meter box, so that the staff can be informed in time and take maintenance measures.

[0022] If there is a problem with the seal, convection will form from the outside to the inside, and the external airflow will cause the local temperature to drop. The fan blades will also rotate, and the speed sensor will capture the speed. At the same time, the force will act on the pressure sensor, causing the pressure detected on the pressure sensor to change. The speed detected by the speed sensor will obviously increase, and the pressure detected on the pressure sensor will obviously increase or decrease, which will further provide the factors causing air leakage in the door gap of the water meter box, and help provide further basis for the situation of air leakage.

The transmission belt 6 is used to drive the second temperature sensor 2 to move along the edge of the door gap of the water meter box 3 to monitor the temperature at the door gap.

[0035] It should be understood that the temperature values ​​detected by the first temperature sensor 1 and the second temperature sensor 2 are always maintained in a non-ideal state, convection may be formed between the internal and external spaces of the water meter box 3, and there is a problem with the seal at the door opening of the water meter box 3. At this time, the transmission belt 6 is started, and the transmission belt 6 drives the second temperature sensor 2 to move at the edge of the door opening of the water meter box 3 through the connecting component.

[0036] As an optional embodiment of the present invention, the connection component includes: A movable track 7, a synchronous plate 9 is fixedly connected to the front end of the end of the movable track 7, and the bottom end of the synchronous plate 9 is rotatably connected to the side edge of the transmission belt 6; A fixed track 8, the fixed track 8 is fixedly installed on the inner bottom surface of the water meter box 3; The docking socket 10 is slidably installed in the fixed track 8, and a first magnetic attraction component is arranged between the docking socket 10 and the fixed track 8, and the first magnetic attraction component is used to position the docking socket 10 on the fixed track 8. A second magnetic attraction component is arranged between the docking socket 10 and the movable track 7. After the first magnetic attraction component cancels the magnetic attraction positioning of the docking socket 10, the second magnetic attraction component is used to magnetically attract the docking socket 10 and magnetically position the docking socket 10 on the movable track 7.

[0037] It should be understood that when the temperature in the water meter box 3 is maintained at an ideal temperature, the docking seat 10 will be positioned in the fixed track 8 under the magnetic attraction of the first magnetic attraction component, and away from the position of the door gap of the water meter box 3 and close to the position of the water meter body 5, which is conducive to detecting the temperature around the water meter body 5 and controlling the temperature around the water meter body 5; However, when the temperature detected by the first temperature sensor 1 and the second temperature sensor 2 always fails to reach the ideal value, it indicates that there may be air leakage inside the water meter box 3. After controlling the first magnetic attraction component to cancel the magnetic attraction positioning of the docking seat 10, the second magnetic attraction component is controlled to magnetically attract the docking seat 10, and the docking seat 10 is magnetically positioned on the movable track 7, so as to prepare for the transmission belt 6 to drive the second temperature sensor 2 to move near the edge of the door gap of the water meter box 3; After the docking seat 10 is docked onto the movable track 7, the transmission belt 6 is started. The transmission belt 6 drives the second temperature sensor 2 near the door gap of the water meter box 3 to move along the track of the door gap of the water meter box 3, so as to uniformly detect the vicinity of the door gap of the water meter box 3, which is beneficial to thoroughly detect the temperature at the door gap of the water meter box 3. If a significant drop in temperature is detected at a certain position, it means that there may be a problem with the sealing at that position, and the staff can be promptly prompted to perform maintenance, which is beneficial to timely solve the door sealing problem of the water meter box 3, and further helps to maintain good antifreeze protection for the water meter body 5.

[0038] As an optional embodiment of the present invention, a transmission assembly is connected between the transmission belt 6 and the edge of the door opening of the water meter box 3, and the transmission assembly includes: An installation groove 11 is provided at the edge of the door opening of the water meter box 3; Four motors 12, the four motors 12 are fixedly mounted at the four corners of the mounting slot 11, and the output ends are fixedly connected with synchronous gears 13, and the surfaces of the four synchronous gears 13 are synchronously connected with the transmission belt 6; The supporting groove 14 is provided on the inner wall of the mounting groove 11 , and a supporting pin 15 is slidably installed in the supporting groove 14 , and the supporting pin 15 is rotatably connected to the synchronous plate 9 .

[0039] It should be understood that when it is necessary to drive the second temperature sensor 2 to move, the four motors 12 are controlled to start synchronously, the four motors 12 synchronously drive the synchronous gears 13 at four positions to rotate, the four synchronous gears 13 synchronously drive the transmission belt 6 to move, the synchronous belt synchronously drives the synchronous plate 9 to move through the connecting assembly, the synchronous plate 9 synchronously drives the docking seat 10 to move, and the docking seat 10 synchronously drives the second temperature sensor 2 to move, thereby realizing the detection of the temperature at the door gap position of the water meter box 3.

[0040] It should be further explained that, by providing the support groove 14 and the support pin 15 , further support is achieved for the synchronization plate 9 , which is beneficial for the synchronization plate 9 and the docking seat 10 to always remain stable during the movement.

[0041] As an optional embodiment of the present invention, the first magnetic attraction component includes: A first electromagnet 16, which is fixedly mounted on the bottom surface of the water meter box 3; The first docking magnet 17 is fixedly mounted on the back of the docking seat 10 and is magnetically matched with the first electromagnet 16 .

[0042] It should be understood that by energizing the first electromagnet 16, the first docking magnet 17 is magnetically attracted, and then the docking socket 10 without the magnetic attraction of the second magnetic attraction component can be pulled until the first docking magnet 17 and the first electromagnet 16 are magnetically attracted, and the second temperature sensor 2 on the docking socket 10 is positioned close to the water meter body 5.

[0044] It should be understood that when it is necessary to detect the position of the door gap near the water meter box 3, after controlling the first magnetic attraction component to cancel the magnetic attraction positioning of the docking socket 10, the second magnetic attraction component is controlled to start, and the second electromagnet 18 is energized to magnetically attract the docking socket 10. The docking socket 10 is magnetically moved, and the docking socket 10 will move from the fixed track 8 to the movable track 7 until the second docking magnet 19 and the second electromagnet 18 are magnetically attracted and magnetically positioned on the movable track 7, so as to prepare for the transmission belt 6 to drive the second temperature sensor 2 to move near the edge of the door gap of the water meter box 3.

[0048] It should be understood that by providing the hot air blower 22, heat is provided to the inside of the water meter box 3. By sucking in the air in the water meter box 3, heating it and then discharging it, an internal heating cycle is formed in the water meter box 3, thereby heating the air in the water meter box 3 and further heating the water meter body 5 in the water meter box 3.

[0049] As a specific implementation of the present invention, a sealing door 23 is hinged at the door opening of the water meter box 3 .

[0050] It should be understood that by providing the sealing door 23, the door opening of the water meter box 3 is sealed. When maintenance is required, the sealing door 23 is opened to provide maintenance space.

[0051] like Figures 1 to 9 A detection system shown includes a temperature monitoring sensor for an antifreeze water meter box, and also includes: The controller 31 is used to control the hot air blower 22 to turn on when the first temperature sensor 1 or the second temperature sensor 2 detects that the temperature is close to zero, so as to heat the inside of the water meter box 3 until the first temperature sensor 1 and the second temperature sensor 2 detect an ideal temperature value; Among them, when the temperature detected by the first temperature sensor 1 or the second temperature sensor 2 still fails to reach the ideal value in the heating state, the first magnetic attraction component is controlled to cancel the magnetic attraction, and then the second magnetic attraction component is controlled to start the magnetic attraction, so that the docking seat 10 is docked on the movable track 7, and then the transmission belt 6 is controlled to drive the second temperature sensor 2 on the docking seat 10 to move at the edge of the door opening of the water meter body 5 to monitor the temperature at the door gap of the water meter body 5.

[0052] Specifically, the controller 31 is fixedly mounted on the surface of the water meter box 3; It should be understood that when the first temperature sensor 1 or the second temperature sensor 2 detects a temperature close to zero degrees, a request message is generated, requesting the controller 31 to control the hot air blower 22 to turn on to heat the interior of the water meter box 3 until the first temperature sensor 1 and the second temperature sensor 2 detect the ideal temperature value.

[0053] In the heating state, when the temperature detected by the first temperature sensor 1 or the second temperature sensor 2 does not reach the ideal value at multiple time points, a request message is generated, requesting the controller 31 to control the first magnetic attraction component to cancel the magnetic attraction, and then control the second magnetic attraction component to start the magnetic attraction, dock the docking seat 10 on the movable track 7, and then control the transmission belt 6 to drive the second temperature sensor 2 on the docking seat 10 to move along the edge of the door opening of the water meter body 5 to monitor the temperature at the door gap of the water meter body 5, thereby realizing automatic detection of the sealing condition of the door gap of the water meter box 3, which is convenient and fast, and is conducive to timely feedback of sealing problems of the water meter box 3, so that the staff can be informed in time and take maintenance measures.

[0054] As a further optimized embodiment of the present invention, it also includes A fixing seat 24, the fixing seat 24 is fixedly connected to the top surface of the docking seat 10, and two connecting pins 25 are fixedly connected to the surface, and a supporting spring 26 is sleeved on the surface of the connecting pin 25; A mounting frame 27, the mounting frame 27 is slidably plugged on the connecting pin 25, the mounting frame 27 and the fixing seat 24 are fixedly connected to the two ends of the supporting spring 26 respectively, and the fan blade 28 is rotatably connected to the mounting frame 27; The pressure sensor 29 is fixedly mounted on the fixing seat 24, and the detection end is in contact with the surface of the mounting frame 27; A rotation speed sensor 30, the rotation speed sensor 30 is mounted on the rotating shaft of the fan blade 28 to detect the rotation speed of the rotating shaft of the fan blade 28; The controller 31 also determines whether there is air leakage at the door gap at the detected corresponding position of the water meter box 3 according to the pressure value detected by the pressure sensor 29 and the rotation speed value detected by the rotation speed sensor 30 . It should be understood that if there is a problem with the seal, and convection is formed from the outside to the inside, the external airflow will cause the local temperature to drop, which will also act on the fan blades 28, and the fan blades 28 will rotate. The speed sensor 30 will capture the speed, and the force will act on the pressure sensor 29, so that the pressure detected by the pressure sensor 29 will change, the speed detected by the speed sensor 30 will be significantly accelerated, and the pressure detected by the pressure sensor 29 will be significantly increased or significantly decreased, thereby further providing the factors of air leakage in the door gap of the water meter box 3, which is helpful to provide a basis for the situation of air leakage; It should be further explained that the increase in the pressure value detected by the pressure sensor 29 is because when the airflow flows into the water meter box 3, it will blow toward the front of the fan blade 28. At this time, the fan blade 28 will push the entire mounting frame 27 inward while rotating, and then squeeze the pressure sensor 29 while squeezing the support spring, thereby forming an increase in the pressure value, indicating that wind has entered; The pressure value detected by the pressure sensor 29 decreases because the airflow flows toward the outside of the water meter box 3 and comes from the back of the fan blade 28. The fan blade 28 also rotates and simultaneously pushes the entire mounting frame 27 outward, thereby releasing the squeezing force at the pressure sensor 29, resulting in a decrease in the pressure value, indicating that there is airflow flowing toward the outside of the door gap.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
