Description

Technical Field

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

[0002] Geothermal heat pump is a new energy utilization technology that uses shallow geothermal energy for heating and cooling. It is a type of heat pump. Heat pump is a device that uses the principles of Carnot cycle and reverse Carnot cycle to transfer cold and heat. Geothermal heat pump usually refers to a device that can transfer heat or cold in the underground soil to where it is needed. Usually heat pumps are used for air conditioning or heating. Geothermal heat pump also uses the huge heat and cold storage capacity of the underground soil. In winter, the ground source transfers heat from the underground soil to the building, and in summer, transfers the cold from the underground to the building, forming a hot and cold cycle in one year.

[0003] A ground source heat pump provided by publication number "CN210165615U" is provided with a plurality of suction cups on the inner wall of a support frame. When the ground source heat pump unit is placed on the support frame, the air on the suction cups is squeezed away, and the bottom of the ground source heat pump is adsorbed on the support frame to avoid vibration when the ground source heat pump unit is started, which causes displacement between the ground source heat pump unit and the support frame, while ensuring the overall stability of the ground source heat pump unit and the mounting plate; telescopic columns and connecting bottom columns that can be retracted up and down are provided between the mounting plate and the four corners of the shock-absorbing bottom plate, and the bottom plate of the lifting frame is sleeved on the sleeve columns. When the motor vibrates, the mounting plate vibrates up and down, and the telescopic columns move up and down along the jacks connecting the bottom columns. The lifting frame slides up and down along the sleeve columns through the sleeve holes, which greatly reduces the vibration and displacement of the shock-absorbing bottom plate.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Since the ground source heat pump is adsorbed and fixed on the suction cup on the support frame, once the ground source heat pump is damaged during actual use, it is not only inconvenient to disassemble the ground source heat pump separately later, but also under long-term vibration force, the suction cup and the ground source heat pump are prone to looseness, thus affecting the stability of the ground source heat pump. Secondly, the first spring and the second spring of the ground source heat pump are prone to elastic potential energy during use, so the ground source heat pump cannot be effectively damped, and its practicality needs to be improved.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] Embodiment 1:

[0027] A ground source heat pump comprises a supporting side panel 1, a ground source heat pump body 2, a control box 3 and a supporting base 4. The left and right end surfaces of the ground source heat pump body 2 are symmetrically provided with supporting side panels 1, and the supporting side panels 1 can support the ground source heat pump body 2. A control box 3 is installed on the left side of the upper end surface of the ground source heat pump body 2. The control box 3 facilitates the staff to control the ground source heat pump. Since the internal detailed structure and working principle of the control box 3 and the ground source heat pump are relatively mature technologies in the prior art, they will not be described in detail here. A supporting base 4 is installed at the bottom of the supporting side panel 1, and the supporting base 4 will support the supporting side panel 1. An installation component 6 for disassembling and assembling the supporting side panel 1 is arranged inside the supporting base 4, so that the ground source heat pump body 2 can be disassembled and assembled more conveniently. A shock-absorbing component 5 is arranged at the lower end of the supporting base 4, and the shock-absorbing component 5 is used to reduce the resonance noise of the ground source heat pump body 2 when it is working.

[0028] The mounting assembly 6 includes a displacement plate 61, a positioning plug 62, a worm 64, a worm wheel 66 and a double-threaded screw 67. A double-threaded screw 67 is installed on the lower side of the support base 4. The external thread on the front side of the annular side of the double-threaded screw 67 rotates in opposite directions to the external thread on the rear side of the annular side. The double-threaded screw 67 with opposite thread rotation directions will drive the displacement plates 61 on the front and rear sides to move synchronously in opposite directions when rotating. The displacement plates 61 are symmetrically arranged on the front and rear sides of the annular side of the double-threaded screw 67. The displacement plates 61 are connected to the positioning plug 62 by welding. 61 will support the positioning block 62. An internal threaded through hole is provided on the lower side of the displacement plate 61, and the internal threaded through hole is engaged with the double-threaded screw 67. The internal threaded through hole enables the displacement plate 61 to move forward and backward when the double-threaded screw 67 rotates. A positioning block 62 is provided on the upper side of the inner wall of the displacement plate 61. Positioning grooves are symmetrically provided on the front and rear end surfaces of the support side plate 1, and the positioning grooves match the protective cover 621. When the positioning block 62 is inserted into the positioning groove, the support side plate 1 is fixed, thereby preventing the ground source heat pump body 2 from shaking during use.

[0029] A worm wheel 66 is arranged on the front side of the annular side of the double-threaded screw 67. The worm wheel 66 is connected to the double-threaded screw 67 by welding. The worm wheel 66 drives the double-threaded screw 67 to rotate. A worm 64 is meshed with the left side of the annular side of the worm wheel 66. The worm 64 is connected to the limit ring 642 and the hand turntable 641 by welding. The worm 64 drives the worm wheel 66 to rotate. The worm 64 and the worm wheel 66 also have self-locking ability to prevent the positioning plug 62 from being easily loosened during use. A A limiting ring 642 and a limiting cover 65 are installed on the front side of the upper end face of the support base 4. The limiting ring 642 and the limiting cover 65 prevent the worm 64 from being displaced up and down during use. A hand turntable 641 is provided on the upper end of the worm 64. A limiting cavity 63 is provided on the upper end face of the support base 4, and the limiting cavity 63 matches the displacement plate 61. The left and right spacing of the inner wall of the limiting cavity 63 is the same as the left and right width of the support side plate 1. The limiting cavity 63 will limit and guide the displacement plate 61 to prevent the displacement plate 61 from being offset or shaking during use.

[0030] The outer surface of the positioning block 62 is wrapped with a protective cover 621, which is made of silicone rubber. The protective cover 621 made of silicone rubber has a certain cushioning property to avoid a large resonance noise between the support side plate 1 and the positioning block 62. A cushion pad 42 is bonded to the lower side of the inner wall of the limiting cavity 63. The cushion pad 42 is made of rubber vibration-damping pad. The cushion pad 42 made of rubber vibration-damping pad can negatively affect the vibration of a part of the supporting side plate 1. An inspection cover 41 is installed on the lower side of the front end surface of the supporting base 4. The inspection cover 41 is a detachable structure. The detachable inspection cover 41 not only blocks and limits the double-threaded screw 67, but also facilitates the later staff to maintain the worm wheel 66 and the worm 64.

[0031] Embodiment 2:

[0032] On the basis of Example 1, in this embodiment, by installing a shock-absorbing seat 51, most of the vibrations transmitted from the support base 4 can be buffered, and the limiting tension spring 56 will apply a downward pulling force to the support base 4 through the limiting column 55 to prevent the support base 4 from jumping upward during use, and the seismic isolation pad 54 can also avoid the resonance noise between the fixed base plate 53 and the external ground, thereby effectively reducing the resonance noise of the ground source heat pump body 2 during operation.

[0033] The anti-vibration assembly 5 includes a shock-absorbing seat 51, a support base 52, a fixed bottom plate 53 and a shock-isolating pad 54. The shock-absorbing seat 51 is symmetrically installed on the front and rear sides of the lower end face of the support base 4. The shock-absorbing seat 51 is made of a damping shock absorber. The shock-absorbing seat 51 made of a damping shock absorber has composite vibration isolation and noise reduction, low natural frequency and good vibration isolation effect, so as to buffer most of the vibrations transmitted from the support base 4. A support base 52 is installed at the lower end of the shock-absorbing seat 51. The support base 52 is connected to the fixed bottom plate 53 by welding. The support base 52 will support the shock-absorbing seat 51. The bottom of the support base 52 is fixedly connected to the fixed bottom plate 53. The fixed bottom plate 53 will support the support base 52. A shock-isolating pad 54 is pasted on the lower end surface of the fixed bottom plate 53. The shock-isolating pad 54 is made of a rubber shock-isolating pad. The shock-isolating pad 54 made of a rubber shock-isolating pad can prevent resonance noise between the fixed bottom plate 53 and the external ground.

[0034] An isolation sleeve 57 is provided in the middle position inside the support base 52, and the isolation sleeve 57 is made of butyl rubber. The isolation sleeve 57 matches the limit column 55. The isolation sleeve 57 made of butyl rubber not only limits the limit column 55, but also avoids resonance noise between the limit column 55 and the support base 52. A limit column 55 is provided in the middle position of the lower end surface of the support base 4, and the limit column 55 matches the isolation sleeve 57. The limit column 55 is connected to the support base 4 by welding. The limit column 55 limits the support base 4 to avoid the support base 4. In case of left-right or front-back deviation during use, a limit spring 56 is connected to the bottom of the limit column 55. The upper end surface of the limit spring 56 is connected to the limit column 55 through an upper connecting ring, and the lower end of the limit spring 56 is connected to the fixed base plate 53 through a lower connecting ring. The limit spring 56 applies a downward pulling force to the limit column 55, thereby preventing the support base 4 from jumping upward during use. Installation through holes are symmetrically provided on the front and back sides of the fixed base plate 53. The installation through holes are convenient for the staff to install and fix the fixed base plate 53 with the help of external expansion bolts.

[0035] Working principle: During the installation of the ground source heat pump body 2, the staff first uses external expansion bolts to install and fix the fixed bottom plate 53 to the specified position of the external cement floor. At this time, the supporting side plate 1 can be placed from top to bottom in the limiting cavity 63, and then the worm 64 is rotated forward by the hand turntable 641, so that the worm 64 drives the double-threaded screw 67 to reverse through the worm gear 66, and the reversed double-threaded screw 67 will drive the displacement plates 61 on the front and rear sides to move inward synchronously, and then the displacement plates 61 on the front and rear sides drive the positioning blocks 62 on the front and rear sides to move inward together and be clamped in the corresponding positioning grooves, so as to fix the bottom of the supporting side plate 1 in the limiting cavity 63 to prevent the ground source heat pump body 2 from being displaced or shaken during use. Similarly, when the staff reverses the worm 64, the displacement plates 61 on the front and rear sides can be moved The positioning blocks 62 on the front and rear sides move outward together, and the supporting side panels 1 can be lifted and disassembled at this time, so as to conveniently disassemble and assemble the ground source heat pump body 2; during the use of the ground source heat pump body 2, the shock absorbing seat 51 made of a damping shock absorber can buffer most of the vibrations transmitted from the supporting base 4, and the limiting tension spring 56 will apply a downward pulling force to the supporting base 4 through the limiting column 55, thereby preventing the supporting base 4 from jumping upward during use. At the same time, the seismic isolation sleeve 57 will not only limit the limiting column 55, but also avoid the resonance noise between the limiting column 55 and the supporting base 52, and the seismic isolation pad 54 made of a rubber vibration damping pad can also avoid the resonance noise between the fixed bottom plate 53 and the external ground, thereby reducing the resonance noise during the operation of the ground source heat pump body 2 and preventing the surrounding staff from being subjected to large resonance noise.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
