Description

Technical Field

[0002] The chiller in the ground source heat pump system, also known as the water source heat pump unit, is a device that uses groundwater, surface water or water in underground pipes as cold and heat sources, and produces cold (hot) air or cold (hot) water through the compressor. This equipment usually includes a heat exchange device on the user side, a compressor and a heat exchange device on the heat source side, and has a single refrigeration or refrigeration and heating function. The role of the chiller in the ground source heat pump system is to provide chilled water in summer, absorb indoor heat through the evaporator, and then release the heat to the groundwater or soil through the condenser to achieve a cooling effect; in winter, the chiller extracts heat from the groundwater or soil, and provides hot water through the condenser to achieve a heating effect.

[0003] In the prior art, chillers are generally placed outdoors for use. In order to prevent the bottom of the chiller from being corroded and the supporting effect between it and the ground from deteriorating, and in order to bear the overall weight of the chiller and keep it stable during long-term use, the supporting part at the bottom of the chiller is set to an integrated low-profile frame structure. This makes the distance between the bottom of the ground source heat pump chiller and the ground very short, making it inconvenient to inspect and repair the bottom. In addition, when the ground source heat pump chiller needs to be moved, it needs to be lifted and moved, which is not convenient to move. Summary of the invention

[0043] Embodiment 1

Support mechanisms 4 are provided on both sides of the main frame 11, and the support mechanisms 4 include two telescopic driving sources, two contact supporting parts and two rolling supporting parts. The two telescopic driving sources are respectively fixedly installed at the lower ends of both sides of the main frame 11, and the two contact supporting parts are respectively located on both sides of the bottom of the main frame 11, and the telescopic ends of the two telescopic driving sources are respectively fixed to the tops of the two contact supporting parts, and the bottoms of the two contact supporting parts and the two rolling supporting parts are higher than the bottom of the main frame 11, and the two rolling supporting parts are respectively connected to the two contact supporting parts.

[0045] For details, please refer to Figures 1 to 4 The contact support portion includes a driving plate 43 and two support plates 42. The top of the driving plate 43 is fixed to the telescopic end of the hydraulic cylinder 41. The two ends of the bottom of the driving plate 43 are fixedly installed with support feet 44. The two support plates 42 are respectively slidably connected to the outer sides of the two support feet 44, and one side of the two support plates 42 is fixed to one side of the main frame 11. The rolling support portion includes two sliding rods 45. The two sliding rods 45 are respectively slidably connected to the two support plates 42. The bottom ends of the two sliding rods 45 are fixedly installed with universal wheels 46. The insides of the two support plates 42 are rotatably installed with transmission gears 47. The outer sides of the two sliding rods 45 and the two support feet 44 are provided with matching tooth grooves 48. The two sides of the two transmission gears 47 are respectively meshed with the two matching tooth grooves 48 at corresponding positions. The telescopic driving source is a hydraulic cylinder 41, and the fixed end of the hydraulic cylinder 41 is fixed to one side of the main frame 11. The support mechanism also includes two limiting parts, which are respectively connected to two support plates 42. The limiting parts include a limiting plate 49, a first bevel gear 410 and a second bevel gear 411. One end of the limiting plate 49 is rotatably connected to the outer side of the support plate 42, one side of the first bevel gear 410 is fixed to the rotating end of the transmission gear 47, and the second bevel gear 411 is fixedly installed on the rotating end of the limiting plate 49, and the outer side of the second bevel gear 411 is meshed with the outer side of the first bevel gear 410.

[0046] It should be noted that, since the various components and specific working principles of the above-mentioned ground source heat pump chiller belong to the prior art and do not belong to the improved solution of the present invention, the principles thereof will not be described in detail here.

[0047] When the bottom of the ground source heat pump chiller 1 needs to be inspected and repaired, it needs to be adjusted to the state of waiting for inspection. At this time, the two hydraulic cylinders 41 can be controlled to start at the same time, and the corresponding two driving plates 43 can be driven to move downward synchronously. The two supporting legs 44 connected to the driving plates 43 extend downward along with the driving plates 43. In the process of the supporting legs 44 moving downward, the matching tooth grooves 48 on one side thereof synchronously drive the transmission gear 47 to rotate, and then the transmission gear 47 drives the sliding rod 45 to move upward, so that the universal wheel 46 moves upward. After the bottom of the supporting leg 44 contacts the ground, the hydraulic cylinder 41 continues to extend, which can drive the entire ground source heat pump chiller 1 to move slowly upward. At the same time, the transmission gear 47 rotates, which can drive the first conical gear 47 to rotate. The wheel 411 rotates, and the second bevel gear 412 starts to rotate under the driving action of the first bevel gear 411, so that the limit plate 49 starts to rotate until the ground source heat pump chiller 1 is lifted to a preset height, and the hydraulic cylinder 41 stops extending, just making the limit plate 49 rotate ninety degrees, so that it is in an expanded state. At this time, the ground source heat pump chiller 1 is in a state of waiting for maintenance. During maintenance, the outer side of the maintenance device is pushed between the two limit plates 49 to limit the maintenance device, so that it can move in the effective area at the bottom of the ground source heat pump chiller 1, and the position of the maintenance device is kept fixed. After the maintenance is completed, the hydraulic cylinder 41 is retracted to drive the support leg 44 to move up and reset, thereby driving the entire ground source heat pump chiller 1 to move down and reset;

[0048] When the entire ground source heat pump chiller 1 needs to be moved, it needs to be adjusted to a mobile state. By controlling the hydraulic cylinder 41 to contract, the driving plate 43 can drive the support leg 44 to move upward. At the same time, the matching tooth groove 48 on one side of the support leg 44 drives the transmission gear 47 to rotate synchronously, so that the transmission gear 47 can drive the slide bar 45 to extend downward, and the universal wheel 46 moves downward with the slide bar 45 until the universal wheel 46 contacts the ground and separates the bottom of the main frame 11 from the ground. The hydraulic cylinder 41 stops contracting. At this time, the mobile state adjustment of the ground source heat pump chiller 1 is completed.

[0049] It can be seen that the present invention provides support for the bottom of the ground-source heat pump chiller 1 by respectively arranging support mechanisms 4 on both sides of the main frame 11, and can realize automatic switching between different usage states of the ground-source heat pump chiller 1. When it is necessary to repair the bottom, the ground-source heat pump chiller 1 can be driven upward as a whole by the support mechanism 4, so that the distance between its bottom and the ground is increased, which is convenient for observing the bottom of the ground-source heat pump chiller and thus reduces the difficulty of maintenance; in addition, when it is necessary to move the ground-source heat pump chiller 1, it can be driven downward by the support mechanism 4 so that the universal wheel 46 is in contact with the ground, thereby facilitating movement. Therefore, the ground-source heat pump chiller 1 arranged in the present invention can meet the requirements for different usage states of the ground-source heat pump chiller 1.

[0050] Embodiment 2

[0051] Please refer to Figure 5 to Figure 6 In order to adapt to the above-mentioned ground-source heat pump chiller and effectively clean its bottom, the present invention discloses a cleaning device, including: a supporting mechanism 2 and a cleaning mechanism 3, wherein the positioning mechanism 2 is connected to the cleaning mechanism 3 and is used to drive the cleaning mechanism 3 to perform a linear reciprocating motion along its length direction; when cleaning the bottom of the ground-source heat pump chiller, the ground-source heat pump chiller is adjusted to a state to be inspected and repaired through the supporting mechanism 4, so that the positioning mechanism 2 is connected with the unfolded limiting part, the position of the positioning mechanism 2 is locked, and the cleaning mechanism 3 is extended to the bottom of the ground-source heat pump chiller for cleaning. The cleaning mechanism 3 includes a water storage component 31, a driving component 32, a brushing component 33 and an adjusting component. The water storage component 31 is used to store cleaning water, and has the function of circulating and filtering the cleaning water. The water storage component 31 includes a water storage tank 312 with an open top; the height adjustment component 34 is used to adjust the height of the brushing component 33; the brushing component 33 is arranged in the water storage tank 312, and the brushing component 33 includes a mounting part and ten cleaning contact parts. The mounting part is rotatably mounted in the water storage tank 312, and the ten cleaning contact parts are evenly linearly distributed along the length direction of the mounting part. The cleaning contact part includes four cleaning brush head monomers, and the four cleaning brush head monomers are circumferentially evenly distributed on the outside of the mounting part with the rotating end of the mounting part as the axis. The driving component 32 is connected to the mounting part. When cleaning the bottom of the ground source heat pump chiller 1, the driving component 32 drives the cleaning brush head monomer to rotate, so that the cleaning brush head monomer located above contacts the bottom of the ground source heat pump chiller 1 and performs a cleaning operation, and the cleaning brush head monomer located below is completely immersed in the cleaning water and performs a self-cleaning action. The remaining cleaning brush head monomers are partially immersed in the cleaning water and bring the cleaning water upward to the bottom of the ground source heat pump chiller 1. The driving component 32 intermittently drives the mounting part and the cleaning contact part to rotate together at a preset angle, so that several cleaning brush head monomers perform brushing operations in rotation.

[0052] Please refer to Figures 6 to 8The water storage component 31 includes a water storage container 311 and a circulation filter assembly. The water storage container is semi-cylindrical. The water storage tank 312 is arranged on the top of the water storage container 311. One end of the water storage container 311 is connected to the positioning mechanism 2. The end of the water storage container 311 close to the positioning mechanism 2 is provided with a water inlet pipe 313, and the end away from the positioning mechanism 2 is provided with a drain 314. The water inlet pipe 313 is used to connect with an external water pipe. One end of the circulation filter assembly is connected to the water inlet pipe 313, and the other end is connected to the drain 314. The circulation filter assembly is used to circulate and filter the cleaning water in the water storage tank 312. The circulation filter assembly includes a circulation water pump 315 and a filter plate 316. The output end of the circulation water pump 315 is connected to the water inlet pipe 313 through a pipeline, and the input end thereof is connected to the drain 314 through a circulation pipeline 317. The filter plate 316 is installed in the drain 314. The filter plate 316 can be an activated carbon plate, which is used to absorb and filter dust in the cleaning water.

[0053] Please refer to Figure 5 and Fig.19 It should be noted that when the water storage component 31 is in use, that is, when the bottom of the ground source heat pump chiller 1 is cleaned, the water inlet pipe 313 is first connected to the external water pipe, and the cleaning water is introduced into the water storage tank 312 through the water inlet pipe 313. When the cleaning water reaches a preset amount, the water inlet amount of the external water pipe is reduced, and then the positioning mechanism 2 is moved to extend the water outlet container to the bottom of the ground source heat pump chiller 1, and the ground source heat pump chiller 1 is cleaned through the cleaning mechanism 3. During the cleaning process, dust follows the cleaning brush head into the water storage tank 312, and the clean water becomes turbid. At this time, the circulating water pump 315 is started to The sewage in the water tank 312 is pumped out, and new clean water is continuously added to the external water pipe. The sewage flows out from the drain port 314, first passes through the filter plate 316, and the dust in the sewage can be filtered out. Then the filtered water enters the circulation pipe 317, and enters the water inlet pipe 313 driven by the circulation water pump 315, mixes with the external clean water and enters the water tank 312 together. In this way, the circulation of cleaning water is realized, and the cleaning water in the water tank 312 can always be kept in a relatively clean state, which can avoid the cleaning water from causing secondary pollution to the ground source heat pump chiller 1 after cleaning. At the same time, when the scrubbing component 33 is self-cleaning, its cleaning effect can also be achieved.

[0054] Please refer to Figures 8 to 12The driving component 32 includes a continuous driving component and an intermittent driving component. The continuous driving component is connected to forty cleaning brush head monomers respectively, and is used to drive the forty cleaning brush head monomers to rotate simultaneously. One end of the intermittent driving component is connected to the continuous driving component, and the other end is connected to the mounting part. The intermittent driving component is used to intermittently drive the mounting part to rotate a preset angle. Since one brush component 33 includes four cleaning brush head monomers, the rotation angle of the intermittent driving mounting part of the intermittent driving group is ninety degrees. The continuous driving component includes a driving motor 321, a rotating rod 322, ten first bevel gears 323 and ten bevel gear sets. The driving motor 321 is fixedly mounted on one end of the water storage container 311 close to the positioning mechanism 2. The rotating rod 322 is rotatably mounted in the mounting portion, one end of which passes through the end of the mounting portion and is fixed to the driving end of the driving motor 321. The number of first bevel gears 323 is the same as that of the cleaning contact portion, both of which are ten. The number of bevel gear sets is the same as that of the first bevel gears 323. The ten first bevel gears 323 are evenly distributed along the length direction of the rotating rod 322. The ten bevel gear sets are distributed one-to-one with the ten first bevel gears 323. The bevel gear set includes four second bevel gears 324. The total number of second bevel gears 324 is the same as that of the cleaning brush head monomers, both of which are forty. The four second bevel gears 324 in one bevel gear set are circumferentially evenly distributed in the mounting portion with the corresponding first bevel gear 323 as the center, and the four second bevel gears 324 in one bevel gear set are meshed with the corresponding first bevel gear 323 together. The intermittent drive assembly includes a transmission gear 325, a transmission gear ring 326, a rotating disk 327, a driving body 328, an electromagnet 3211 and a control switch 3212. The transmission gear 325 is fixedly sleeved on one end of the rotating rod 322 close to the driving motor 321. The rotating disk 327 is rotatably connected to one end of the water storage container 311. The transmission gear ring 326 is fixedly installed on one side of the transmission gear 325. The bottom of the transmission gear 325 is meshed with the transmission gear 325. The driving body 328 is fixedly installed at one end of the mounting portion. One side of the driving body 328 is provided with four matching grooves 329. The four matching grooves 329 are evenly distributed on the driving body 328. One side of the rotating disk 327 is fixedly installed with a matching sliding shaft 330 that matches the matching grooves 329. 210, the electromagnet 3211 is fixedly installed at one end of the water storage container 311 close to the driving body 328, and one side of the electromagnet 3211 is in contact with the driving body 328. After being energized, the electromagnet 3211 can magnetically adsorb and fix the driving body 328 so that it will not rotate. The control switch 3212 is installed at one end of the water storage container 311 close to the electromagnet 3211. The control switch 3212 is used to control the power on and power off of the electromagnet 3211. The control switch 3212 can be an infrared sensing switch or a press-type delayed switch. When the control switch 3212 is triggered, the electromagnet 3211 in the energized state can be controlled to be powered off immediately. After the preset time is reached, the control switch 3212 automatically resets, so that the electromagnet 3211 automatically conducts electricity.

[0055] It should be noted that when the driving component 32 is in use, that is, when the bottom of the geothermal heat pump chiller 1 is cleaned, the cleaning brush head monomer located above is in contact with the bottom of the geothermal heat pump chiller 1, and the driving motor 321 is rotated to drive the rotating rod 322 to rotate, so that the first bevel gear 323 on the rotating rod 322 respectively drives the second bevel gear 324 meshing therewith to rotate, and the second bevel gear 324 rotates, so that the corresponding cleaning brush head monomer can rotate on its own, and the cleaning brush head monomer located above rotates on its own to contact the bottom of the geothermal heat pump chiller 1, so that its bottom can be scrubbed, and at the same time When the cleaning mechanism 3 is moved linearly by the positioning mechanism 2, the cleaning brush head monomer can be evenly scrubbed along the bottom of the ground source heat pump chiller 1. At the same time, the transmission gear 325 rotates with the rotating rod 322, and drives the transmission gear ring 326 and the rotating disk 327 to rotate together. When the matching sliding shaft 3210 on the rotating disk 327 moves and slides with the matching groove 329, the matching sliding shaft 3210 triggers the control switch 3212, so that the electromagnet 3211 is immediately powered off, and the fixing effect on the driving body 328 is lost. At this time, the driving body 328 can rotate with the rotating matching sliding shaft 3210, and The mounting portion and the cleaning contact portion rotate with the driving body 328. When the matching sliding shaft 3210 moves and separates from the matching sliding groove, the control switch 3212 reaches the preset disconnection time and automatically resets, so that the electromagnet 3211 is immediately energized and generates magnetic force again to fix the driving body 328, so that the driving body 328 no longer rotates. At this time, the driving body 328 also rotates exactly ninety degrees, and the cleaning brush head monomer located above is rotated to a horizontal state, and the cleaning brush head monomer originally in a horizontal state is driven to an upper position, and continues to scrub the bottom of the ground source heat pump chiller 1, thus completing the cleaning brush head unit. The automatic switching of the body enables multiple cleaning brush head units to scrub the bottom of the geothermal heat pump chiller 1 in turn, and the cleaning brush head units located on both sides can lift the cleaning water in the water storage tank 312 by rotating, so that the cleaning water flows to the bottom of the geothermal heat pump chiller 1, thereby automatically completing the water spraying action while scrubbing the geothermal heat pump chiller 1, and the cleaning brush head unit located at the bottom is completely immersed in the cleaning water, and can perform self-cleaning operation through its self-rotation, which can clean the dust and impurities on its surface, avoiding secondary pollution to the bottom of the geothermal heat pump chiller 1 when it contacts the geothermal heat pump chiller 1 next time.

[0056] It can be seen that the driving component 32 provided in the present invention, by being used in conjunction with the brushing component 33, realizes the self-cleaning function of the cleaning brush head unit during the brushing process of the bottom of the geothermal heat pump chiller 1, so that the cleaning brush head unit remains in a relatively clean state, avoiding secondary pollution to the bottom of the geothermal heat pump chiller 1, so as to improve the cleaning effect of the geothermal heat pump chiller 1. In addition, by driving multiple cleaning brush head units to rotate the cleaning action, the cleaning brush head unit can be protected to a certain extent, avoiding the problem of long-term contact and brushing of the cleaning brush head with the geothermal heat pump chiller 1 and causing greater wear. The driving component 32 provided in the present invention, in addition to having the function of driving multiple cleaning brush head units to rotate at the same time, can also automatically match the brushing frequency of the brushing component 33, and intermittently drive the entire brushing component 33 to rotate a preset angle, thereby completing the posture switching of different cleaning brush head units.

[0057] Please refer to Figure 14 to Figure 15 The mounting portion is a support sleeve 331, one end of the support sleeve 331 is rotatably connected to one side of the inner wall of the water storage tank 312, and the other end thereof extends through the water storage tank 312 to the outside of the water storage container 311. The cleaning brush head unit includes a rotating seat 332, an adaptive adjustment member and seven cleaning brush heads 333. One end of the rotating seat 332 is rotatably connected to the support sleeve 331, and the second bevel gear 324 is fixed to the end of the rotating seat 332. The adaptive adjustment member is arranged on one side of the rotating seat 332. The seven cleaning brush heads 333 are detachably mounted on one end of the adaptive adjustment member. The detachable cleaning brush head 333 is convenient for replacement. The cleaning brush head 333 is made of a wear-resistant and elastic plastic material, which is consistent with the cleaning head of an existing highway sweeper; the adaptive adjustment member is used to adjust the spacing of the cleaning brush heads 333. The adaptive adjustment part includes a fixed rod 334, a sliding sleeve 335, a contact ball 336, a support spring 337, six swing rods 338 and six connecting rotating rods 339. The fixed rod 334 is fixedly installed on one side of the rotating seat 332, the sliding sleeve 335 is slidably sleeved on the upper end of the fixed rod 334, the contact ball 336 is rotatably installed on the top of the sliding sleeve, the support spring 337 is fixed between the sliding sleeve 335 and the fixed rod 334, the number of the swing rods 338 and the connecting rotating rods 339 is the same, the six swing rods 338 are circumferentially uniformly rotated and installed on one side of the rotating seat 332 with the fixed rod 334 as the center, the six cleaning brush heads 333 are correspondingly detachably installed on the ends of the swing rods 338, the six connecting rotating rods 339 are correspondingly hinged to one side of the six swing rods 338, and the other ends of the six connecting rotating rods 339 are jointly hinged to the outer side of the sliding sleeve 335.

[0058] It should be noted that when the above-mentioned brushing component 33 is in use, before brushing the bottom of the ground source heat pump chiller 1, it is necessary to adjust the height of the cleaning brush head monomer through the height adjustment component 34, so that the adaptive adjustment component is in a compressed state, that is, the contact ball 336 contacts the bottom of the ground source heat pump chiller 1, and squeezes the contact ball 336 and the sliding sleeve 335 to move downward together, so that the support spring 337 is in a compressed state, and then under the driving action of the continuous driving component, the rotating seat 332 can rotate with the second bevel gear 324, and the fixed rod 334, the sliding sleeve 335, and the connecting rod 336 are connected to the ground source heat pump chiller 1. The contact ball 336, the swing rod 338, the connecting rod 339 and the cleaning brush head 333 rotate together with the rotating seat 332. The cleaning brush head 333 rotates to contact the bottom of the ground source heat pump chiller 1, so that the dust on the bottom of the ground source heat pump chiller 1 can be brushed off. When the cleaning brush head unit moves to a position where the bottom of the ground source heat pump chiller 1 is recessed or lower than the initial position, the contact ball 336 is no longer squeezed by the ground source heat pump chiller 1, and under the elastic force of the support spring 337, the sliding sleeve 335 and the contact ball 336 can be driven to automatically move upward, and the swing rod The sliding sleeve 335 drives the connecting rotating rod 339 to rotate and move closer to the fixing rod 334, thereby increasing the height of the cleaning brush head 333 on the connecting rotating rod 339, so that the cleaning brush head 333 can adapt to the recessed position, ensuring that the top of the cleaning brush head 333 contacts the recessed position, thereby effectively cleaning the cleaning brush head 333. When the contact ball 336 moves to a position closer to the bottom surface of the ground source heat pump chiller 1, the contact ball 336 can be squeezed to move downward, so that the sliding sleeve 335 moves downward and squeezes the supporting spring 337 to contract, and finally the cleaning brush head 333 expands outward to lower the cleaning brush head 333. The height of the head 333 automatically adapts to the position. In this way, the cleaning brush head unit provided by the present invention has the function of adaptive expansion and contraction, so that it can well adapt to the cleaning positions of different heights at the bottom of the ground source heat pump chiller 1, ensuring that the cleaning brush head unit is in effective contact with the cleaning position to ensure the cleaning effect of the ground source heat pump chiller 1; in addition, compared with the existing integrated brush head structure, it is provided with multiple detachable cleaning brush heads 333, and a single damaged cleaning brush head 333 can be replaced separately, thereby avoiding the waste of resources caused by replacing the entire brush head.

[0059] In addition, it should be noted that when the cleaning brush head 333 unit is rotated from an upper position to a horizontal position, the contact ball 336 will be squeezed by the inner wall of the water storage tank 312, so that the cleaning brush head 333 unit is in an outward expansion state. In this way, the diameter of the cleaning brush head 333 unit is increased. When it rotates, more cleaning water can be lifted to the bottom of the ground source heat pump chiller 1 to meet the water demand during the cleaning process.

[0060] Please refer to Fig.16The height adjustment component 34 includes a connecting seat 341, a fixing frame 342 and an adjusting rotating rod 343. The connecting seat 341 is connected to the driving end of the positioning mechanism 2, the fixing frame 342 is fixed to the end of the water storage container 311, the upper end of the fixing frame 342 is slidably connected to the connecting seat 341, and the adjusting rotating rod 343 is threadedly connected to one end of the fixing frame 342, and its top end passes through the top of the fixing frame 342 and is rotatably connected to the bottom of the connecting seat 341; when using the height adjustment component 34 to adjust the height of the water storage component 31, it is only necessary to rotate the adjusting rotating rod 343. At this time, since the fixing frame 342 is restricted by the sliding of the connecting seat 341, it can move up and down along the connecting seat 341, thereby driving the water storage container 311 to move up and down, and finally the cleaning brush head 333 can be squeezed by the bottom of the ground source heat pump chiller 1 and is in a compressed state.

[0061] Please refer to Fig.17 The positioning mechanism 2 includes a support frame 21, a driving motor 22, a transmission screw 23 and a connecting slider 24. Both ends of the support frame 21 are provided with matching slots 26 adapted to the limit plate 49. The driving motor 22 is fixed at one end of the support frame 21. The transmission screw 23 is rotatably installed in the support frame 21, and its end is fixed to the driving end of the driving motor 22. The connecting slider 24 is slidably installed on the top of the support frame 21, and the bottom of the connecting slider 24 is connected to the connecting seat 341. Pulleys are also provided on both sides of the support frame 21, and the pulleys have a self-locking function.

[0062] It should be noted that when the positioning mechanism 2 is in use, that is, during the cleaning process of the ground source heat pump chiller 1, the entire cleaning device is moved to the side of the ground source heat pump chiller 1 by moving the positioning mechanism 2. At this time, the ground source heat pump chiller 1 is adjusted to a state to be inspected and repaired by the support mechanism 4. By pushing the positioning mechanism 2, the matching slots 26 at both ends of the support frame 21 are matched and plugged with the two limit plates 49. Through the matching plug-in effect of the two, the position of the support frame 21 is positioned, so that the entire cleaning device is kept in contact with the ground source heat pump chiller 1. Stable connection, when the cleaning mechanism 3 moves on the positioning mechanism 2 for cleaning, the entire cleaning device is not prone to position displacement, thereby ensuring the cleaning effect of the cleaning mechanism 3; and during specific cleaning, by driving the motor 22 to rotate, the transmission screw 23 can be driven to rotate, and the connecting slider 24 begins to move along the length direction of the support frame under the rotation action of the transmission screw 23, thereby driving the cleaning mechanism 3 to move in a straight line, so that it can move in a straight line along the bottom of the ground source heat pump chiller 1, and then evenly scrub the bottom of the ground source heat pump chiller 1.

[0063] Please refer to Fig.17 and Fig.18Furthermore, in order to realize the automatic expansion and contraction function of the cleaning mechanism 3, the present invention optimizes the above scheme, specifically: the positioning mechanism 2 also includes a flip component 25, the flip component 25 includes a flip gear 251, a driving tooth plate 252 and a torsion spring 253, the flip gear 251 is rotatably installed in the connecting slider 24, the bottom of the flip gear 251 is fixed to the top of the connecting seat 341, the torsion spring 253 is fixed between the flip gear 251 and the connecting seat 341, and the driving tooth plate 252 is fixed to one side of the support frame 21, and one side of the support frame 21 is provided with a contraction groove 254 adapted to the cleaning mechanism 3.

[0064] The cleaning device of the present invention is in a retracted state before use, that is, the cleaning mechanism 3 is retracted inside the retracted slot 254, and the torsion spring 253 is also in a compressed state. When cleaning is needed, the cleaning mechanism 3 needs to be adjusted to the expanded state. During adjustment, the motor 22 is driven to rotate, so that the connecting slider 24 and the cleaning mechanism 3 can slide together. When the flip gear 251 follows the connecting slider 24 to move to mesh with the driving tooth plate 252, as the connecting slider 24 continues to move, the flip gear 251 can be rotated along the driving tooth plate 252, thereby driving the cleaning mechanism 3 to rotate together, so that the cleaning mechanism 3 is flipped from the inside of the retracted slot 254 to the outside, and the torsion spring 253 is also As the cleaning mechanism 3 rotates, it gradually resets until the cleaning mechanism 3 rotates to an angle of ninety degrees with the support frame 21, and the flip gear 251 is just separated from the driving tooth plate 252, thus completing the automatic deployment action of the cleaning mechanism 3. After cleaning is completed, the connecting slider 24 is moved and reset, so that the flip gear 251 is engaged with the driving tooth plate 252 again, and finally drives the cleaning mechanism 3 to flip and shrink into the shrinkage groove 254; in this way, the cleaning device provided by the present invention also has an automatic folding and shrinking function, which is more convenient to use without manual adjustment of the state when in use, and is adjusted to a retracted state when not in use to reduce its volume for easy movement and storage.

A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
