Description

Technical Field

[0001] This utility model belongs to the field of heating technology, and specifically relates to a heating temperature monitoring and self-adjusting device. Background Technology

[0002] Heating systems are indispensable for warmth in the harsh winters of northern China. In centralized heating systems, hot water is transported by hydraulic pipelines to various heat exchange stations. These stations are where heat is exchanged; primary heat sources transfer heat to secondary heat sources via heat exchangers. The secondary heat sources are then delivered to users via heating pipelines.

[0003] Heating systems typically use a closed-loop water circulation system with a hot water boiler to heat primary hot water and send it to various heat exchange stations. The heat is then transferred to secondary hot water via heat exchangers. After being pressurized by a secondary circulation pump, the secondary hot water is delivered to households. However, during the process of transferring heat from the primary hot water to the secondary hot water via heat exchangers, significant heat loss is common. This necessitates the installation of heating temperature monitoring devices to monitor the secondary hot water in real time. However, adjusting the temperature of the secondary hot water is inconvenient, time-consuming, and labor-intensive, which can negatively impact heating efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0013] Furthermore, the drive assembly includes a mounting box, the bottom of which is fixedly mounted to the top of the sealing plate, a motor is fixedly mounted to the top of the mounting box, a rotating rod is fixedly connected to the output end of the motor, two sets of driving gears are rotatably arranged on the outer surface of the rotating rod, two sets of driven gears are meshed on the surfaces of the two sets of driving gears, and the interiors of the two sets of driven gears are fixedly connected to the outer surfaces of the threaded seat and the ball valve core, respectively.

[0014] The outer surface of the rotating rod is provided with a slot, and a locking block is slidably disposed inside the slot.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model uses a lifting component to move downwards, thereby driving a drive component that rotates internally to move downwards, thus adjusting the movement of the drive component. Then, the drive component is activated, causing the adjusting component to rotate. When the adjusting component rotates, it rotates inside the mounting block, enabling communication within the mounting block. This allows secondary hot water entering the mounting block to flow out from the other end. When the temperature of the secondary hot water exceeds a standard value, the lifting component is activated to move upwards, causing the drive component to move upwards, facilitating adjustment of its movement. Then, the drive component is activated to drive the adjusting component to rotate, allowing cold water to enter the adjusting component and neutralize it with the secondary hot water. A detection component monitors the temperature of the neutralized secondary hot water, facilitating temperature adjustment. This method is time-saving and labor-saving, thus avoiding any impact on heating efficiency.

[0018] 2. This utility model uses the rotation of the threaded seat to drive the threaded rod connected internally to move up and down. When the threaded rod moves, it can drive the sealing plug fixedly installed on its outer surface to move. Since the outer surface of the sealing plug is interference-fitted with the inner wall of the sealing cylinder, and the inside of the sealing cylinder is connected to the inside of the cold water pipe, when the sealing plug moves, it can release the seal on the cold water pipe, thereby connecting the inside of the cold water pipe with the inside of the sealing cylinder. By adjusting the position of the sealing plug, the gap between the cold water pipe and the sealing cylinder can be changed, thus facilitating the control of the flow rate of cold water entering the inside of the sealing cylinder through the cold water pipe, thereby achieving the effect of controlling the temperature of the secondary hot water.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-6As shown, this utility model is a heating temperature monitoring and self-adjusting device, including a mounting block 1, a connecting component 2 inside the mounting block 1, a detection component 3 fixedly installed inside the mounting block 1, an adjustment component 4 fixedly installed at the top of the mounting block 1, a drive component 5 fixedly installed at the top of the adjustment component 4, the output end of the drive component 5 fixedly installed on the outer surface of the adjustment component 4, and a lifting component 6 fixedly installed at the top of the drive component 5, with the lifting end of the lifting component 6 rotatably disposed from the outer surface of the drive component 5.

[0032] In use, the connecting component 2 is flanged to the water pipe of the heat exchange station, and the cold water is flanged to one end of the regulating component 4. This allows secondary hot water to enter the mounting block 1 through the connecting component 2. The detection component 3 monitors the temperature of the water entering the mounting block 1. If the temperature does not reach the standard value, the connecting component 2 is activated, allowing the secondary hot water to flow back and be reheated. When the temperature reaches the standard value, the lifting component 6 is activated, moving it downwards. This moves the drive component 5, which rotates within it, downwards, thus adjusting the movement of the drive component 5. The drive component 5 is then activated, causing the regulating component 4 to rotate. As the regulating component 4 rotates, it moves within the mounting block 1... The rotating part allows the interior of the mounting block 1 to be connected, so that when secondary hot water enters the interior of the mounting block 1, it can flow out from the other end. When the temperature of the secondary hot water is higher than the standard value, the lifting component 6 is activated to move it upward, which in turn drives the drive component 5 to move upward, making it easy to adjust the movement mode of the drive component 5. Then, the drive component 5 is activated to drive the regulating component 4 to rotate, so that cold water can enter the interior of the regulating component 4 and neutralize it with the secondary hot water. The detection component 3 detects the temperature of the neutralized secondary hot water and drives the regulating component 4 to operate in real time through the drive component 5, so as to adjust the amount of cold water entering and control the temperature of the neutralized secondary hot water, which is quite convenient.

[0033] This invention uses a lifting component 6 to move downwards, which in turn moves the drive component 5, which is internally rotated, downwards. This allows for adjustment of the movement of the drive component 5. Then, the drive component 5 is activated, causing the adjusting component 4 to rotate. When the adjusting component 4 rotates, it rotates inside the mounting block 1, creating a connection within the mounting block 1. This allows secondary hot water entering the mounting block 1 to flow out from the other end. When the temperature of the secondary hot water exceeds a standard value, the lifting component 6 is activated, moving upwards and causing the drive component 5 to move upwards. This facilitates adjustment of the drive component 5's movement. The drive component 5 then drives the adjusting component 4 to rotate, allowing cold water to enter the adjusting component 4 and neutralize the secondary hot water. The temperature of the neutralized secondary hot water is detected by the detection component 3, allowing for temperature adjustment. This process is time-saving and labor-saving, thus avoiding any impact on heating efficiency.

[0034] In one embodiment, the connection component 2 includes a hot water pipe 201, an outlet pipe 202, and a return pipe 203. One end of the hot water pipe 201 is fixedly connected to one end of the mounting block 1, one end of the outlet pipe 202 is fixedly connected to the other end of the mounting block 1, one end of the return pipe 203 is connected to the interior of the mounting block 1, and a one-way solenoid valve 204 is fixedly installed inside the return pipe 203.

[0035] By connecting the hot water pipe 201 to the secondary hot water pipe in the heat exchange station with a flange, connecting the outlet pipe 202 to the inlet pipe with a flange, and connecting the return pipe 203 to the heat exchange device with a flange, when the temperature of the secondary hot water inside the hot water pipe 201 is not up to standard as detected by the detection component 3, the one-way solenoid valve 204 is activated to allow the secondary hot water inside to flow back and be reheated, which is quite convenient.

[0036] In one embodiment, the detection component 3 includes two sets of mounting slots 301, both sets of mounting slots 301 are opened on one side of the mounting block 1, and temperature detectors 302 are fixedly installed inside both sets of mounting slots 301.

[0037] Both the mounting slot 301 and the temperature detector 302 are provided with two sets, one set is connected to the inside of the hot water pipe 201 and the other set is connected to the inside of the outlet pipe 202, which facilitates the detection of the secondary hot water entering and flowing out of the mounting block 1, and facilitates the self-adjusting device for heating temperature monitoring to regulate the temperature of the secondary hot water.

[0038] In one embodiment, the adjustment component 4 includes a sealing plate 401, the bottom end of which is fixedly installed with the top end of the mounting block 1. A spherical valve core 402 is rotatably disposed inside the sealing plate 401. The outer surface of the spherical valve core 402 is rotatably disposed with the interior of the mounting block 1. A connection hole 403 is provided at the top end of the spherical valve core 402.

[0039] A U-shaped frame 404 is fixedly installed on the top of the sealing plate 401, and a sealing cylinder 405 is fixedly installed on the top of the U-shaped frame 404. The interior of the sealing cylinder 405 is fitted against the inner wall of the connecting hole 403, and a cold water pipe 406 is fixedly connected to the interior of the sealing cylinder 405.

[0040] By connecting one end of the cold water pipe 406 to an external cold water supply via a flange, cold water can easily enter the interior of the cold water pipe 406. Since the interior of the cold water pipe 406 is connected to the interior of the sealing cylinder 405, and the interior of the sealing cylinder 405 is connected to the interior of the ball valve core 402 through the connecting hole 403, the cold water inside the cold water pipe 406 can enter the interior of the sealing cylinder 405 and then into the interior of the ball valve core 402. When the ball valve core 402 rotates and connects the hot water pipe 201 to the outlet pipe 202, cold water can enter its interior and neutralize it with the secondary hot water, thereby facilitating the temperature control of the secondary hot water.

[0041] In one embodiment, the adjustment component 4 further includes a sealing cover 407, the interior of which is threadedly rotatable with the outer surface of the sealing cylinder 405. A rotating seat 408 is fixedly installed at the top of the sealing cover 407, and a threaded seat 409 is rotatably provided at the top of the rotating seat 408. A threaded rod 410 is threadedly connected to the interior of the threaded seat 409, and a sealing plug 411 is fixedly installed on the outer surface of the threaded rod 410. The outer surface of the sealing plug 411 is interference-fitted with the inner wall of the sealing cylinder 405.

[0042] By rotating the threaded seat 409, the threaded rod 410 connected internally moves up and down. When the threaded rod 410 moves, it can move the sealing plug 411 fixedly installed on its outer surface. Since the outer surface of the sealing plug 411 is interference-fitted with the inner wall of the sealing cylinder 405, and the inside of the sealing cylinder 405 is connected to the inside of the cold water pipe 406, when the sealing plug 411 moves, it can release the seal on the cold water pipe 406, thereby connecting the inside of the cold water pipe 406 with the inside of the sealing cylinder 405. By adjusting the position of the sealing plug 411, the gap between the cold water pipe 406 and the sealing cylinder 405 can be changed, thereby facilitating the control of the flow rate of cold water entering the sealing cylinder 405 through the cold water pipe 406, thus achieving the effect of controlling the secondary hot water temperature.

[0043] In one embodiment, the drive assembly 5 includes a mounting box 501, the bottom of which is fixedly mounted to the top of a sealing plate 401. A motor 502 is fixedly mounted on the top of the mounting box 501. A rotating rod 503 is fixedly connected to the output end of the motor 502. Two sets of driving gears 504 are rotatably arranged on the outer surface of the rotating rod 503. Two sets of driven gears 505 are meshed on the surfaces of the two sets of driving gears 504. The interiors of the two sets of driven gears 505 are fixedly connected to the outer surfaces of the threaded seat 409 and the ball valve core 402, respectively.

[0044] The outer surface of the rotating rod 503 is provided with a slot 506, and a locking block 507 is slidably disposed inside the slot 506. A locking wheel 508 is fixedly connected to one side of the locking block 507, and a locking tooth 509 is fixedly connected to the top of the drive gear 504. The surface of the locking tooth 509 meshes with the surface of the locking wheel 508.

[0045] The motor 502 drives the rotating rod 503, which is fixedly connected to its output end, to rotate. When the rotating rod 503 rotates, it can drive the slot 506 on its outer surface to rotate. Since a locking block 507 is slidably arranged inside the slot 506, and one side of the locking block 507 is fixedly connected to the inside of the locking wheel 508, when the slot 506 rotates, it can cooperate with the locking block 507 to drive the locking wheel 508 to rotate. Since the surface of the locking wheel 508 meshes with the surface of the locking tooth 509, when the locking wheel 508 rotates, it can drive the locking tooth 509 to rotate. Since the driving gear 504 is provided in two sets, and each of its surface is meshed with a driven gear 505, when the locking tooth... When 509 rotates, it drives one set of driving gears 504 fixedly connected to its bottom end to rotate. When one set of driving gears 504 rotates, it drives one set of driven gears 505 meshing on its surface to rotate. When the chuck 508 moves upward and meshes with the chuck teeth 509 at the bottom end of another set of driving gears 504, it drives the other set of driven gears 505 to rotate. Since the interiors of the two sets of driven gears 505 are fixedly installed on the outer surfaces of the threaded seat 409 and the ball valve core 402 respectively, they can drive the threaded seat 409 and the ball valve core 402 to be controlled separately, thus improving the effectiveness of the heating temperature monitoring and self-adjusting device.

[0046] In one embodiment, the lifting assembly 6 includes an electric push rod 601, the bottom end of which is fixedly installed with the top end of the mounting box 501, and a connecting plate 602 is fixedly installed on the telescopic end of the electric push rod 601. The interior of the connecting plate 602 is rotatably configured with respect to the outer surface of the chuck 508.

[0047] The electric push rod 601 drives the connecting plate 602, which is fixedly installed at its output end, to move up and down. When the connecting plate 602 moves up and down, it can drive the chuck 508, which is rotated inside, to move, thereby facilitating the adjustment of the position of the chuck 508.

[0048] Through the above technical solution, 1. The lifting component 6 is moved downward, which in turn drives the drive component 5, which is rotated inside it, to move downward, thereby adjusting the movement mode of the drive component 5. Then, the drive component 5 is activated, which drives the adjustment component 4 to rotate. When the adjustment component 4 rotates, it can rotate inside the mounting block 1, thereby enabling the internal connection of the mounting block 1. When the secondary hot water enters the mounting block 1, it can flow out from the other end. When the temperature of the secondary hot water is higher than the standard value, the lifting component 6 is activated, which moves upward, thereby driving the drive component 5 to move upward, facilitating the adjustment mode of the drive component 5. Then, the drive component 5 is activated, which drives the adjustment component 4 to rotate, thereby facilitating the entry of cold water into the adjustment component 4 and neutralizing it with the secondary hot water. The temperature of the neutralized secondary hot water is detected by the detection component 3, which facilitates the adjustment of the secondary hot water temperature. This method is more time-saving and labor-saving, thereby avoiding affecting the heating effect.

[0049] 2. By rotating the threaded seat 409, the threaded rod 410 connected internally moves up and down. When the threaded rod 410 moves, it can move the sealing plug 411 fixedly installed on its outer surface. Since the outer surface of the sealing plug 411 is interference-fitted with the inner wall of the sealing cylinder 405, and the inside of the sealing cylinder 405 is connected to the inside of the cold water pipe 406, when the sealing plug 411 moves, it can release the seal on the cold water pipe 406, thereby connecting the inside of the cold water pipe 406 with the inside of the sealing cylinder 405. By adjusting the position of the sealing plug 411, the gap between the cold water pipe 406 and the sealing cylinder 405 can be changed, thereby facilitating the control of the flow rate of cold water entering the sealing cylinder 405 through the cold water pipe 406, thus achieving the effect of controlling the secondary hot water temperature.
