[0003] At present, after long-term use, a large amount of dirt is easily generated inside the structure of the intelligent heat exchanger unit, and users need to clean the dirt inside the structure regularly to ensure that the use of the heat exchanger unit is not affected.

[0004] When cleaning the existing intelligent heat exchanger unit, the user needs to manually disassemble the structure inside the unit before cleaning it accordingly. When using a cleaning mechanism for cleaning, the cleaning mechanism cannot perform corresponding cleaning work on the inside of the circulating water pipe in multiple ways in the water pipe, so that the cleaning effect of the pipe is not comprehensive enough. Summary of the invention

[0005] In view of the technical problems existing in the prior art, the present invention provides an intelligent heat exchanger unit to solve the problem that when the existing intelligent heat exchanger unit needs to be decontaminated after long-term use, the user needs to manually perform the decontamination work, which causes inconvenience to the user.

[0006] The technical solution of the present invention for solving the above-mentioned technical problems is as follows: an intelligent heat exchanger unit, characterized in that it includes a circulating water pipe and a dirt removal shell, and two inner cavities are symmetrically opened in the dirt removal shell, the inner circumferential wall of one of the inner cavities is fixedly connected with a transmission motor, the output shaft end of the transmission motor is fixedly connected with a transmission shaft, and the outer circumferential wall of one end of the transmission shaft is fixedly connected with a cleaning wheel, the dirt removal shell is slidingly connected to the circulating water pipe through the cleaning wheel, the outer circumferential wall of the other end of the transmission shaft is meshingly connected with a crawler, the inner circumferential wall of the other inner cavity is fixedly connected with a vacuum cleaner, and the outer circumferential wall of the vacuum cleaner is symmetrically provided with two air cylinders, and the ends of the two air cylinders are fixedly connected with suction plates, the outer circumferential wall of the dirt removal shell is fixedly connected with a decontamination ring, the decontamination ring is in conflict with the inner circumferential wall of the circulating water pipe, and one side of the dirt removal shell is fixedly connected with a moving mechanism.

[0007] The beneficial effects of the present invention are:

[0008] When the user needs to clean the dirt in the circulating water pipe, a dirt removal shell is set in the circulating water pipe, and the transmission motor drives the crawler and three cleaning wheels to rotate, so that during the rolling process, the three cleaning wheels clean the inner wall of the circulating water pipe, and during the cleaning, the moving mechanism drives the dirt removal shell to move accordingly, so that the cleaning effect of the dirt removal shell is more comprehensive.

[0009] The suction plate and the decontamination ring can perform corresponding decontamination work on the inner wall of the circulating water pipe during the movement of the decontamination shell, so that the user does not need to manually disassemble the heat exchanger unit for decontamination work. At the same time, there are multiple cleaning methods for cleaning the circulating water pipe.

[0010] Based on the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, a servo motor is fixedly connected to the top of the circulating water pipe, and a turntable is fixedly connected to the end of the output shaft of the servo motor; three circular grooves are opened in the turntable, and valves are fixedly connected to the inner walls of two of the circular grooves; the inner diameter of the other circular groove is adapted to the diameter of the decontamination shell.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that when the dirt removal shell needs to pass through a position similar to a stop valve connected to a circulating water pipe, such a valve is first connected to the turntable, that is, three circular grooves are opened in the turntable, and only one circular groove needs to be left in a through state, while valves are set in the other circular grooves, and then the turntable is driven to rotate by the servo motor to switch the three circular grooves, so that when the through circular grooves are connected, they can provide a passable passage for the dirt removal shell, and the other circular grooves are provided with corresponding valves according to user needs to facilitate the operation of the heat exchanger unit, thereby assisting the dirt removal shell to comprehensively clean the dirt in the circulating water pipe.

[0013] Furthermore, a cavity is opened in the turntable, and the inner circumferential wall of the cavity is fixedly connected with an electric telescopic rod, the end of the electric telescopic rod is fixedly connected with a linkage shaft, and the outer circumferential wall of the linkage shaft is symmetrically provided with two connecting rods, the two connecting rods are rotatably connected to the linkage shaft, and the ends of the two connecting rods are hingedly connected with rings; one side of the two rings is fixedly connected with a sealing ring, and the sealing ring is adapted to the sealing groove.

[0014] The beneficial effect of adopting the above further scheme is that after the corresponding circular groove is connected to the circulating water pipe, the intersection angle of the two connecting rods can be changed by extending and retracting the electric telescopic rod, so that the user can indirectly control the distance between the two rings in this way.

[0015] Furthermore, the outer peripheral wall of the collar is fixedly connected with a T-shaped limit block, and the outer peripheral wall of the T-shaped limit block is slidably connected with a limit sliding groove.

[0016] The beneficial effect of adopting the above-mentioned further scheme is that, since the diameter of the T-shaped limit block is adapted to the inner diameter of the limit slot, the T-shaped limit block can slide normally in the limit slot while the limit slot limits the T-shaped limit block so that the connection angle between the T-shaped limit block and the limit slot is in a vertical state, thereby avoiding changes in the connection angle between the two, thereby ensuring smooth movement of the ring.

[0017] Furthermore, a sealing groove is provided in the circulating water pipe.

[0018] The beneficial effect of adopting the above further scheme is that the sizes of the sealing groove and the sealing ring are adapted, so that the two can be engaged with each other after the sleeve ring drives the sealing ring to move, so that the gap between the turntable and the circulating water pipe can be filled, thereby achieving a sealing effect to ensure the sealing performance of the three circular grooves after switching.

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] The intelligent heat exchanger unit is mainly composed of: heat exchanger, voltage stabilizer, circulation pump, water supply pump, decontamination device, control cabinet, etc. Some need to add condensate tank or water supply tank and softening device, which is equivalent to heat exchange station. All thermal projects that require heat exchange station can be replaced by intelligent heat exchanger units. At present, when the intelligent heat exchanger units on the market are cleaned, users need to manually disassemble the structure inside the unit before they can perform the corresponding cleaning work. When using the cleaning mechanism for cleaning, the cleaning mechanism cannot be moved in the water pipe to perform the cleaning work, so that the cleaning range of the pipeline is not comprehensive enough. At the same time, the cleaning mechanism is easily blocked by valves such as stop valves, resulting in the movement of the cleaning mechanism being restricted. When there is a channel for the cleaning mechanism to pass through the unit, the sealing performance of the water pipe cannot be guaranteed, which makes the automatic cleaning function of the cleaning mechanism on the water pipe impossible to achieve, so that users can only manually remove the dirt in the water pipe.

[0032] During the use of the intelligent heat exchanger unit, it is inconvenient for users to clean the internal dirt, the cleaning is not comprehensive, and the sealing performance of the circulating water pipe during the cleaning process cannot be guaranteed. In this regard, the inventors have proposed an intelligent heat exchanger unit to solve the above problems.

[0033] The present invention provides the following preferred embodiments

[0034] like Figure 1 and Figure 5As shown in FIG. 6 , an intelligent heat exchange unit includes a circulating water pipe 1 and a decontamination shell 5. The decontamination shell 5 has two symmetrical inner chambers 501. A transmission motor 502 is fixedly connected to the inner wall of one of the inner chambers 501. A transmission shaft 504 is fixedly connected to the output shaft end of the transmission motor 502. A cleaning wheel 505 is fixedly connected to the outer wall of one end of the transmission shaft 504. The decontamination shell 5 is slidably connected to the circulating water pipe 1 through the cleaning wheel 505. The outer wall of the other end of the transmission shaft 504 is meshed with a crawler 503. A vacuum cleaner 506 is fixedly connected to the inner wall of the other inner chamber 501. The outer wall of the vacuum cleaner 506 is symmetrically arranged. There are two air ducts 507, and one side of the dirt removal shell 5 is fixedly connected with a moving mechanism 6. By arranging the dirt removal shell 5 in the circulating water pipe 1, the transmission motor 502 drives the crawler 503 and the three cleaning wheels 505 to rotate, and during the rolling process, the three cleaning wheels 505 clean the inner circumferential wall of the circulating water pipe 1, and during the cleaning, the moving mechanism 6 drives the dirt removal shell 5 to move accordingly, so that the cleaning effect of the dirt removal shell 5 is more comprehensive. At the same time, in this process, the suction plate 508 and the dirt removal ring 509 (the dirt removal ring mainly plays the role of wiping dust) perform corresponding dirt removal work on the inner circumferential wall of the circulating water pipe 1.

[0035] It should be noted that the moving mechanism 6 includes an electric drive wheel moving assembly 61 and a rotating motor 62. The electric drive wheel moving assembly 61 is used to drive the entire decontamination housing 5 to move along the circulating water pipe 1. The rotating motor 62 is used to drive the entire decontamination housing 5 to revolve along the circulating water pipe 1. A pressure sensor is fixedly arranged on the rotating motor 62. The pressure sensor is electrically connected to the electric drive wheel moving assembly 61 and the rotating motor 62 respectively. When the decontamination housing 5 rotates to clean the dirt on the wall of the circulating water pipe, if there is stubborn dirt adhering to the wall of the circulating water pipe that cannot be removed by the decontamination ring 509, In the case of simple wiping, as the dirt removal housing 5 continues to rotate, the cleaning wheel 505 will come into contact with the dirt on the wall of the water pipe, and will repeatedly wipe the dirt under multiple rotations of the cleaning wheel 505 until it is wiped off. When the cleaning wheel 505 wipes the dirt multiple times, the pressure sensor on the rotating motor 62 senses the resistance generated when the cleaning wheel contacts the dirt, causing the rotating motor 62 to pause rotating for a period of time and the electric drive wheel travel assembly 61 to stop moving forward for a period of time (10 seconds in this embodiment), so that the cleaning wheel 505 can wipe the dirt within the preset time.

[0036] In this embodiment, Figure 5 , Figure 6 , Figure 8 and Fig. 9As shown, in order to further improve the cleaning effect of the dirt removal shell 5 on the dirt in the circulating water pipe 1, the ends of the two air tubes 507 are fixedly connected with suction plates 508, and the outer peripheral wall of the dirt removal shell 5 is fixedly connected with a cleaning ring 509, which is formed by a brush ring. The cleaning ring 509 is in contact with the inner peripheral wall of the circulating water pipe 1. During the movement of the dirt removal shell 5, the suction plate 508 and the cleaning ring 509 can perform corresponding cleaning work on the inner peripheral wall of the circulating water pipe 1, so that the user does not need to manually disassemble the heat exchanger unit for cleaning work. A cleaning groove is also provided inside the dirt removal shell 5, which is located on the inner side of the cleaning wheel 505. The cleaning groove is provided with a scraper 8 which is close to the cleaning wheel 505. A collecting chamber 9 is opened in the middle of the dirt removal shell 5, and a material guide groove 10 is provided between the collecting chamber 9 and the cleaning groove. An internal vacuum cleaner 11 is provided in the collecting chamber 9, and a dust suction hose 12 is provided between the internal vacuum cleaner 11 and the material guide groove 10. The dirt cleaned by the cleaning wheel 505 will be scraped off by the scraper 8 during the rotation and fall into the cleaning groove, where suction is generated in the internal vacuum cleaner 11, and the material guide groove 10 is connected through the dust suction hose 12 to collect the dirt, so as to avoid excessive dirt adhering to the cleaning wheel 505 and affecting the cleaning effect. The guide groove 10 is hinged with an electric control door 13, a transmission groove 14 is opened on one side of the guide groove 10, a toggle rod 15 is provided in the transmission groove 14 and extends into the guide groove 10, a transmission spring 17 connected to the toggle rod 15 is provided in the guide groove 10, a shaking rod 16 extending to the inner side wall of the scraper 8 is provided in the transmission groove 14, a rebound spring 19 connected to the transmission groove 14 is also provided in the transmission groove 14, and a first triangular toggle is provided on the outer side of the shaking rod 16 near the toggle rod 15. The other end of the rebound spring 19 is fixedly connected to the first triangular toggle block 20, and a mounting column 18 is installed on the side of the toggle rod 15 close to the shaking rod 16. The inner side of the end of the mounting column 18 close to the shaking rod 16 is provided with a second triangular toggle block 21 matching the first triangular toggle block 20. Before the internal vacuum cleaner 11 is started, the electric control door 13 will first start to fold inward. At this time, the electric control door 13 pushes the toggle rod 15 to move inward, and the transmission spring 17 is compressed. During the movement of the toggle rod 15, the mounting column 18 and the shaking rod 16 move alternately, so that the first triangular toggle block on the shaking rod 16 touches the second triangular toggle block 21, driving the shaking rod 16 to move downward, and at the same time the rebound spring 19 is compressed. When the second triangular toggle block 21 is separated from the first triangular toggle block 20, the rebound of the rebound spring 19 drives the shaking rod 16 to collide with the scraper 8, so that the dust adhered to the scraper 8 can be knocked off during the continuous collision process, thereby avoiding excessive dust adhered to the contact point between the scraper 8 and the cleaning wheel 505, affecting the scraping effect of the scraper 8.

[0037] In this embodiment, Figure 1 , Figure 3 and Figure 7As shown, in order to further improve the decontamination range of the decontamination housing 5, a servo motor 2 is fixedly connected to the top of the circulating water pipe 1, and a turntable 3 is fixedly connected to the output shaft end of the servo motor 2. Three circular grooves 301 are opened in the turntable 3, and valves 302 are fixedly connected to the inner circumferential walls of two circular grooves 301. The inner diameter of the other circular groove 301 is adapted to the diameter of the decontamination housing 5. When the decontamination housing 5 needs to pass through a position similar to a stop valve connected to the circulating water pipe 1, firstly, such a valve 302 is connected to the turntable. 3 is connected, that is, three circular grooves 301 are opened in the turntable 3, only one circular groove 301 needs to be left in a through shape, and the other circular grooves 301 are provided with valves 302, and then the turntable 3 is driven to rotate by the servo motor 2 to switch the three circular grooves 301, so that the through circular groove 301 can provide a passable passage for the decontamination housing 5 when it is connected to the circulating water pipe 1, and the other circular grooves 301 are provided with corresponding valves 302 according to user needs to facilitate the operation of the heat exchange unit.

[0038] In this embodiment, Figure 1 As shown in FIG. 4 , in order to further improve the sealing performance of the circulating water pipe 1 during the decontamination process of the decontamination housing 5, a cavity 303 is provided in the turntable 3, and the inner peripheral wall of the cavity 303 is fixedly connected with an electric telescopic rod 4, and the end of the electric telescopic rod 4 is fixedly connected with a linkage shaft 401, and the outer peripheral wall of the linkage shaft 401 is symmetrically provided with two connecting rods 402, and the two connecting rods 402 are rotatably connected to the linkage shaft 401, and the ends of the two connecting rods 402 are hingedly connected with a collar 403, and a sealing groove 1 is provided in the circulating water pipe 1. 01, one side of the two rings 403 is fixedly connected with a sealing ring 406, and the sealing ring 406 is adapted to the sealing groove 101. After the corresponding circular groove 301 is connected to the circulating water pipe 1, the crossing angle of the two connecting rods 402 can be changed by telescoping the electric telescopic rod 4, so that the spacing between the two rings 403 can be indirectly controlled, so that it can drive the sealing ring 406 to be clamped in the sealing groove 101, thereby ensuring the sealing performance of the three circular grooves 301 after switching.

[0039] In this embodiment, Figure 2 As shown, in order to further improve the smoothness of the movement of the ring 403, the outer wall of the ring 403 is fixedly connected with a T-shaped limit block 404, and the outer wall of the T-shaped limit block 404 is slidably connected with a limit slot 405. Since the diameter of the T-shaped limit block 404 is adapted to the inner diameter of the limit slot 405, the T-shaped limit block 404 can slide normally in the limit slot 405 while being limited by the limit slot 405, so that the connection angle between the T-shaped limit block 404 and the limit slot 405 is in a vertical state, avoiding changes in the connection angle between the two, thereby ensuring the smooth movement of the ring 403.

[0040] The specific working process of the present invention is as follows:

[0041] Switching preparation before decontamination

[0042] First, the electric telescopic rod 4 is shortened to reduce the distance between the two rings 403, so that the sealing ring 406 in a sealed state is separated from the sealing groove 101, so that a gap is left between the turntable 3 and the circulating water pipe 1 at this time, thereby allowing the user to drive the turntable 3 to rotate by driving the servo motor 2 with electric energy, so that the three circular grooves 301 are switched, and the circular groove 301 without a valve 302 is connected to the circulating water pipe 1.

[0043] Seal again after switching

[0044] After the circular groove 301 without the valve 302 is connected to the circulating water pipe 1, the user drives the electric telescopic rod 4 associated with the circular groove 301 to extend with electric energy, so that the distance between the two rings 403 here can be expanded, and the sealing ring 406 can be clamped with the sealing groove 101, so as to fill the gap between the circulating water pipe 1 and the turntable 3.

[0045] Electric control of decontamination housing movement

[0046] After preparation is completed, the user controls the transmission motor 502 to operate with electric energy, so that it can drive the three cleaning wheels 505 to rotate simultaneously through the track 503, so that it can clean the inner wall of the circulating water pipe 1, and at the same time, the moving mechanism 6 drives the decontamination shell 5 to move accordingly in the circulating water pipe 1.

[0047] Decontamination

[0048] During the movement of the dirt removal shell 5, the vacuum cleaner 506 can be operated first, so that the rotation of the dirt removal shell 5 can drive the suction plate 508 to rotate to absorb the dirt in the circulating water pipe 1. At the same time, the dirt removal ring 509 can wipe the unabsorbed dirt in the process of contacting with the inner wall of the circulating water pipe 1, so as to further clean the dirt.

[0049] Switch again after decontamination is complete

[0050] After the decontamination is completed, in the same way as above, the user drives the electric telescopic rod 4 to extend and retract and the servo motor 2 to rotate by electric energy, so that the circular groove 301 with the valve 302 is re-linked with the circulating water pipe 1, and then the sealing work is performed to ensure that the subsequent circulating water pipe 1 can allow the heat exchange liquid to circulate normally.

[0051] In summary, the beneficial effect of the present invention is specifically embodied in that when the heat exchange unit needs to be cleaned after long-term use, the user does not need to manually clean it. The user only needs to control the servo motor 2, the electric telescopic rod 4 and the transmission motor 502 accordingly so that they can operate accordingly in the circulating water pipe 1, so that the decontamination housing 5 can automatically decontaminate the circulating water pipe 1 to prevent the dirt from affecting the heat exchange effect of the heat exchange unit;

[0052] When the heat exchange unit needs to be decontaminated, a decontamination shell 5 is arranged in the circulating water pipe 1, and the transmission motor 502 drives the crawler 503 and the three cleaning wheels 505 to rotate, so that during the rolling process, the three cleaning wheels 505 clean the inner peripheral wall of the circulating water pipe 1, and during the cleaning, the moving mechanism 6 drives the decontamination shell 5 to move accordingly, so that the cleaning effect of the decontamination shell 5 is more comprehensive, and at the same time, the suction plate 508 and the decontamination ring 509 (the decontamination ring mainly plays the role of wiping dust) perform corresponding decontamination work on the inner peripheral wall of the circulating water pipe 1;

[0053] If stubborn dirt adheres to the wall of the circulating water pipe and cannot be simply wiped off by the cleaning ring 509, the cleaning housing 5 continues to rotate, causing the cleaning wheel 505 to come into contact with the dirt on the wall of the water pipe, and repeatedly wipe the dirt under multiple rotations of the cleaning wheel 505 until it is wiped off. When the cleaning wheel 505 wipes the dirt multiple times, the pressure sensor on the rotating motor 62 senses the resistance generated when the cleaning wheel contacts the dirt, causing the rotating motor 62 to stop rotating for a period of time and the electric drive wheel travel assembly 61 to stop moving forward for a period of time (10 seconds in this embodiment), so that the cleaning wheel 505 can wipe the dirt within this preset period of time.

[0054] When the heat exchange unit needs to be decontaminated, when the decontamination shell 5 needs to pass through a position similar to a stop valve connected to the circulating water pipe 1, firstly, such a valve 302 is connected to the turntable 3, that is, three circular grooves 301 are opened in the turntable 3, and only one circular groove 301 needs to be left in a through shape, and the other circular grooves 301 are provided with valves 302, and then the servo motor 2 is driven to rotate the turntable 3 after operation, so that the three circular grooves 301 are switched, so that the through circular groove 301 can provide a passable passage for the decontamination shell 5 when it is connected to the circulating water pipe 1, and the other circular grooves 301 are provided with corresponding valves 302 according to user needs to facilitate the operation of the heat exchange unit;

[0055] When the heat exchanger unit needs to be decontaminated, after the corresponding circular groove 301 is connected to the circulating water pipe 1, the electric telescopic rod 4 can be extended and retracted to change the crossing angle of the two connecting rods 402, so as to indirectly control the spacing between the two rings 403, so that it can drive the sealing ring 406 to be clamped in the sealing groove 101, thereby ensuring the sealing performance of the three circular grooves 301 after switching.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
