Description

Technical Field

[0001] The utility model relates to the technical field of heat pumps, in particular to a heat pump internal machine case. Background Art

[0002] A heat pump is a highly efficient and energy-saving device that makes full use of low-grade thermal energy. Heat can be transferred spontaneously from a high-temperature object to a low-temperature object, but cannot spontaneously proceed in the opposite direction. The working principle of a heat pump is a mechanical device that forces heat from a low-temperature object to a high-temperature object in a reverse cycle. It only consumes a small amount of reverse cycle net work to obtain a large amount of heating capacity, and can effectively utilize low-grade thermal energy that is difficult to apply to achieve energy-saving purposes. The heat pump internal machine chassis is a device used to cover the heat pump internal machine core, but since the heat pump internal machine chassis in the existing technology is mainly composed of sheet metal components, the device is easily deformed during the lifting process, which reduces the safety of the device during transportation, thereby affecting the practicality of the device.

[0003] Based on this, the utility model designs a heat pump inner machine case to solve the above problems. Utility Model Content

[0013] (3) Beneficial effects

[0014] Compared with the prior art, the present invention provides a heat pump internal machine chassis, which has the following beneficial effects:

[0015] 1. The heat pump internal unit chassis uses a lifting assembly to enable the extension rod to drive the internal threaded seat to move along the lifting sleeve. After the distance adjustment hole on the inner side of the extension rod is moved to the set position, it is fixed to the lifting sleeve by the distance adjustment bolt and distance adjustment nut, and then the external lifting ring is screwed and fixed to the inside of the internal threaded seat. At this time, sufficient extension distance is obtained between the two sets of external lifting rings, and the sling fixed on the external lifting ring is kept separate from the device, which reduces the probability of deformation of the device during lifting, improves the safety of the device during transportation, and thus enhances the practicality of the device.

[0016] 2. The heat pump internal machine chassis uses a buffer component 2 to cause the lifting frame to displace under the action of vibration force. During the displacement of the lifting frame, the reciprocating spring is driven to deform. After the deformation, the reciprocating spring resets and drives the lifting frame to move back and forth. The lifting frame in the reciprocating movement drives the damping rubber column to deform. During the deformation process, the damping rubber column buffers and reduces the vibration force, thereby reducing the impact of the vibration of the movement in the device, thereby enhancing the practicality of the device.

[0017] 3. The heat pump internal chassis controls the start-up of the enhanced cooling fan through the temperature switch, so that the enhanced cooling fan on the left drives the external air into the internal sheet metal chassis, and the enhanced cooling fan on the right drives the air output in the sheet metal chassis. In this process, the heat emitted by the movement in the device is carried away by the flowing air. After the temperature in the sheet metal chassis drops to the set range, the temperature switch controls the enhanced cooling fan to turn off, which effectively improves the heat dissipation capacity of the device and greatly reduces the heat dissipation energy consumption of the device, thereby enhancing the practicality of the device.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3The utility model provides a technical solution: a heat pump internal machine chassis, including a sheet metal chassis 1, a buffer assembly 2 is provided at the bottom of the sheet metal chassis 1, and the buffer assembly 2 causes the lifting frame 4 to displace under the action of the vibration force. During the displacement process of the lifting frame 4, the reciprocating spring 5 is driven to deform. After the deformation, the reciprocating spring 5 resets and drives the lifting frame 4 to reciprocate. The lifting frame 4 in the reciprocating movement drives the damping rubber column 6 to deform. During the deformation process, the damping rubber column 6 buffers and reduces the vibration force, thereby reducing the impact of the vibration of the movement in the device, thereby enhancing the practicality of the device. The buffer assembly 2 includes a supporting frame 3, and the lifting frame 4 is provided on the upper side of the supporting frame 3. The supporting frame 3 and the lifting frame 4 are connected. There are multiple groups of reciprocating springs 5 and damping rubber columns 6 in between. A limit ring 7 is provided on the top of the lifting frame 4. The limit ring 7 is fixed to the sheet metal chassis 1 through multiple groups of limit screws 8. Two groups of lifting components 9 are provided at the bottom of the lifting frame 4. Through the lifting components 9, the extension rod 11 drives the internal thread seat 12 to move along the lifting sleeve 10. After the distance adjustment hole 15 on the inner side of the extension rod 11 is moved to the set position, it is fixed to the lifting sleeve 10 through the distance adjustment bolt 13 and the distance adjustment nut 14, and then the external lifting ring is screwed and fixed to the inside of the internal thread seat 12. At this time, sufficient extension distance is obtained between the two groups of external lifting rings, and the sling fixed on the external lifting ring is kept separate from the device, which reduces the deformation of the device during the lifting process. The probability of change is improved, the safety of the device during transportation is improved, thereby enhancing the practicality of the device, each set of lifting components 9 includes a lifting sleeve 10, the inner wall of each set of lifting sleeves 10 can be slidably plugged with two sets of extension rods 11, the outer end of each set of extension rods 11 is plugged with an internal threaded seat 12, and each set of extension rods 11 is fixed to the corresponding lifting sleeve 10 through an adjusting bolt 13 and an adjusting nut 14. Two sets of adjusting holes 15 are provided on the top and bottom of each set of extension rods 11, and the outer surface of each set of adjusting bolts 13 is slidably plugged with the inner wall of the corresponding adjusting hole 15. The left and right sides of the sheet metal chassis 1 are provided with a standby cooling fan 16 and multiple sets of enhanced cooling fans 17. The left and right sides of the box 1 are connected to detection tubes, and each set of detection tubes is screwed with a temperature switch 18. The output ends of each set of temperature switches 18 are electrically connected to the input ends of the enhanced cooling fans 17. The enhanced cooling fans 17 are started by controlling the temperature switches 18, so that the enhanced cooling fan 17 on the left drives the external air into the internal sheet metal chassis 1, and the enhanced cooling fan 17 on the right drives the air output inside the sheet metal chassis 1. In this process, the heat emitted by the movement in the device is carried away by the flowing air. After the temperature inside the sheet metal chassis 1 drops to the set range, the temperature switch 18 controls the enhanced cooling fan 17 to turn off, which effectively improves the heat dissipation capacity of the device and greatly reduces the heat dissipation energy consumption of the device, thereby enhancing the practicality of the device.

[0024] In the present utility model, in order to improve the safety during the operation of the device, a tensioning ring 19 is provided on the outer side of each group of standby cooling fans 16 and enhanced cooling fans 17, and the inner wall of each group of tensioning rings 19 is provided with an isolation mesh plate 20 for separating personnel from the rotating parts of the standby cooling fans 16 and enhanced cooling fans 17. At the same time, the isolation mesh plate 20 filters and separates dust particles in the air entering the device, thereby improving the safety during the operation of the device.

[0025] In the present invention, in order to reduce the probability of damage and failure of the internal thread seat 12 during the standby process, a protective plug cover 21 is screwed on the inner wall of each group of internal thread seats 12 to reduce the collision of foreign objects therewith, and the outer surface of each group of protective plug covers 21 is provided with multiple groups of reinforcing ribs, thereby reducing the probability of damage and failure of the internal thread seat 12 during the standby process.

[0026] In the present invention, in order to reduce the probability of damage to the placement position during the transportation of the device, buffer pads 22 are provided at the four corners of the bottom of the supporting frame 3 to buffer and reduce the impact force during the placement of the device through elastic deformation. The bottom of each set of buffer pads 22 is provided with multiple sets of anti-slip grooves, thereby reducing the probability of damage to the placement position during the transportation of the device.

[0027] In the present invention, in order to reduce the probability of deformation of the sheet metal chassis 1, a plurality of groups of conformal reinforcing ribs 23 are provided on the outer surface of the sheet metal chassis 1 for improving its structural strength. The width of each group of conformal reinforcing ribs 23 is twice the thickness of the sheet metal chassis 1, thereby reducing the probability of deformation of the sheet metal chassis 1.

[0028] In the present invention, in order to reduce the probability of displacement during the transportation of the device, limiting plates 24 for limiting the movement of the two are provided on the left and right sides of the supporting frame 3 and the lifting frame 4. The two sets of adjacent limiting plates 24 are fixedly installed by limiting bolts and limiting nuts, thereby reducing the probability of displacement during the transportation of the device.

[0029] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.

[0030] During use, first assemble and fix the movement to the inside of the sheet metal chassis 1. After the movement is assembled, the internal threaded seat 12 is driven to move along the lifting sleeve 10 by the extension rod 11. After the distance adjustment hole 15 on the inner side of the extension rod 11 is moved to the set position, it is fixed to the lifting sleeve 10 by the distance adjustment bolt 13 and the distance adjustment nut 14. Then the external lifting ring is screwed and fixed to the inside of the internal threaded seat 12. At this time, a sufficient extension distance is obtained between the two sets of external lifting rings, and the sling fixed on the external lifting ring is kept separate from the device. Then the device is hoisted and transported to the set position. After the device is placed firmly, repeat the above operation in reverse to reset the extension rod 11. Then the movement in the device performs heat pump operation. During the operation of the movement in the device, vibration will be generated, and the lifting frame 4 will be displaced under the action of the vibration force. During the displacement of the lifting frame 4, the reciprocating spring 5 is driven to deform, and the reciprocating spring 5 is reset after deformation. The spring 5 drives the lifting frame 4 to move back and forth, and the lifting frame 4 in reciprocating motion drives the damping rubber column 6 to deform. The vibration force is buffered and reduced during the deformation of the damping rubber column 6. At the same time, during the operation of the movement in the device, the left standby cooling fan 16 drives the external air inside the sheet metal chassis 1, and the right standby cooling fan 16 drives the air output in the sheet metal chassis 1. During this process, the heat emitted by the movement in the device is taken away by the flowing air. When the temperature in the device exceeds the set range, the temperature switch 18 controls the enhanced cooling fan 17 to start, and the left enhanced cooling fan 17 drives the external air inside the sheet metal chassis 1, and the right enhanced cooling fan 17 drives the air output in the sheet metal chassis 1. During this process, the heat emitted by the movement in the device is taken away by the flowing air. After the temperature in the sheet metal chassis 1 drops to the set range, the temperature switch 18 controls the enhanced cooling fan 17 to turn off.

[0031] To sum up, the heat pump internal machine chassis, through the lifting component 9, makes the extension rod 11 drive the internal threaded seat 12 to move along the lifting sleeve 10. After the inner adjusting hole 15 of the extension rod 11 is moved to the set position, it is fixed to the lifting sleeve 10 by the adjusting bolt 13 and the adjusting nut 14, and then the external lifting ring is screwed and fixed to the inside of the internal threaded seat 12. At this time, sufficient extension distance is obtained between the two groups of external lifting rings, and the sling fixed on the external lifting ring is kept separated from the device, which reduces the probability of deformation of the device during lifting, improves the safety of the device during transportation, and thus enhances the practicality of the device.

[0032] The heat pump internal machine chassis uses a buffer component 2 to cause the lifting frame 4 to displace under the action of vibration force. During the displacement process, the lifting frame 4 drives the reciprocating spring 5 to deform. The reciprocating spring 5 that resets after deformation drives the lifting frame 4 to move back and forth. The lifting frame 4 in the reciprocating movement drives the damping rubber column 6 to deform. During the deformation process, the damping rubber column 6 buffers and reduces the vibration force, reduces the impact of the vibration of the movement in the device, and thus enhances the practicality of the device.

[0033] The heat pump internal chassis controls the enhanced cooling fan 17 to start through the temperature switch 18, so that the left enhanced cooling fan 17 drives the external air into the internal sheet metal chassis 1, and the right enhanced cooling fan 17 drives the air out of the sheet metal chassis 1. In this process, the heat emitted by the movement in the device is carried away by the flowing air. After the temperature in the sheet metal chassis 1 drops to the set range, the temperature switch 18 controls the enhanced cooling fan 17 to turn off, which effectively improves the heat dissipation capacity of the device and greatly reduces the heat dissipation energy consumption of the device, thereby enhancing the practicality of the device.
