Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger fixing equipment, in particular to an underground heat exchanger fixing device for a ground source heat pump monitoring hole. Background Art

[0002] Ground-source heat pump technology is a renewable energy technology. The shallow surface layer of the earth acts as a massive solar collector, collecting 47% of the sun's energy. Unrestricted by geography or resources, ground energy is a clean, renewable energy source. However, existing underground heat exchangers are typically fixed with screws. However, repairs and disassembly require unscrewing the screws before replacement, and subsequent reinstallation is cumbersome and inconvenient.

[0003] A Chinese utility model patent with the announcement number CN216925278U discloses a ground source heat pump monitoring hole underground heat exchanger fixing device, comprising a base, a connecting seat, and a heat exchanger. The base is mounted on the top of the connecting seat, and the heat exchanger is mounted on the top of the connecting seat. The connecting seat has slots on both the left and right sides and the front and back ends, and the inner cavity of the base is mounted with a fixing mechanism. The ground source heat pump monitoring hole underground heat exchanger fixing device rotates the rotating rod clockwise, and the second gear can drive the first gear to rotate counterclockwise, so that the screw can follow the counterclockwise rotation. At the same time, the threaded barrel can move outward from the outer wall of the screw, so that the block moves out of the inner cavity of the slot, thereby releasing the fixing of the connecting seat. The device can easily disassemble and assemble the heat exchanger without the need for additional tools, saving time and effort, and facilitating the promotion and use of the device.

[0004] Regarding the above-mentioned related technologies, the utility model applicant believes that there are the following defects:

[0005] When performing the limit installation, the above-mentioned device does not take into account the shaking factors that may occur in the actual equipment during use. The vibration generated by the equipment during operation will gradually impact the connection, and then the equipment with threaded connections at the bottom will deflect under the force, which will deteriorate the fixing effect and may cause the heat exchanger to shift and affect normal use. Utility Model Content

[0006] In order to solve the technical problem that the existing equipment lacks an anti-loosening limit design when fixing the heat exchanger, which easily causes the equipment to deviate during actual operation and affects the normal use of the equipment, the utility model provides an underground heat exchanger fixing device for a ground source heat pump monitoring hole.

[0007] The utility model is implemented by the following technical solutions: a fixing device for an underground heat exchanger of a ground source heat pump monitoring hole, comprising a mounting platform;

[0008] A heat exchanger device is installed on the upper end of the installation platform;

[0009] A locking mechanism, comprising a limit assembly and an adjustment assembly, wherein the limit assembly is disposed on the upper end of the mounting platform and is used to fix the heat exchanger device, and the adjustment assembly is disposed on the upper end of the mounting platform and is used to control the limit assembly;

[0010] The anti-loosening mechanism is arranged at the upper end of the mounting platform and is used to lock the adjustment component.

[0011] Through the above technical solution, the locking mechanism can realize the quick expansion of the limit assembly under the control of its own adjustment assembly, so as not to hinder the installation and disassembly of the heat exchanger equipment. Moreover, since the limit assembly can be easily taken out after expanding outward, the heat exchanger equipment can be installed and quickly positioned after aligning the positioning block on the upper end of the installation platform. Then, the heat exchanger equipment can be locked under the adjustment control of the adjustment assembly; and then the adjustment mechanism can be locked under the anti-loosening mechanism to avoid the loosening of the equipment locking mechanism due to shaking, thereby further ensuring the stability of the equipment connection.

[0012] As a further improvement of the above scheme, the limiting assembly includes connecting vertical rods, a top plate and an alignment groove. The connecting vertical rods are divided into four groups and are respectively arranged around the heat exchanger equipment. The top end of the connecting vertical rod is connected to the top plate, and the inner side of the top plate is provided with an alignment groove for connecting and limiting the heat exchanger equipment.

[0013] Through the above technical solution, four sets of connecting vertical rods are installed at the four corners of the heat exchanger equipment, and the positioning grooves correspond to the four corners of the top of the heat exchanger equipment. The heat exchanger equipment can be pressed down and fixed with the cooperation of the adjustment component, and the stability of the heat exchanger equipment can be guaranteed under the support force of the top of the installation platform.

[0014] As a further improvement of the above scheme, the adjustment component includes a connecting slide, a limit block, a sleeve plate, a blocking block and a connecting groove. The outer walls of the four groups of connecting vertical rods are all provided with a connecting slide, and the bottom ends of the four groups of connecting vertical rods are all provided with a limit block. The four groups of connecting vertical rods are all rotatably connected in the sleeve plate, and the inner sides of the four groups of sleeve plates are all provided with a blocking block.

The top of the mounting platform is located at the sleeve plate and a connecting groove is opened. The connecting groove is used for the vertical sliding of the sleeve plate and the connecting vertical rod.

[0015] Through the above technical solution, the blocking block is used to abut and block the limit block, so that the connecting vertical rod can only maintain a vertical state and rotate outward at most, thereby preventing the connecting vertical rod from rotating inward and affecting the installation. The sliding setting of the connecting groove and the connecting slide ensures the stability of the adjustment component during adjustment and will not deflect.

[0016] As a further improvement of the above scheme, the adjustment assembly also includes a bottom rod and a connecting base plate. The bottom ends of the four groups of sleeves are connected to the bottom rod, and bottom connecting strips are provided on both sides of the four groups of bottom rods. The bottom connecting strips are used to slide vertically in the connecting groove. The bottom ends of the four groups of bottom rods are all provided on the upper part of the connecting base plate. The middle part of the connecting base plate is connected to a threaded sleeve block, and a screw is threadedly connected to the inner thread of the threaded sleeve block. The top end of the screw is rotatably connected to the bottom end of the mounting platform.

[0017] Through the above technical solution, the threaded connection between the screw and the threaded sleeve and the vertical sliding connection are utilized to ensure that the equipment can be vertically displaced and moved during adjustment, and when performing locking adjustment, it can be automatically returned to its original position under the abutment and push of the connecting groove under the rotational connection between the sleeve and the connecting vertical rod, thereby maintaining the verticality and locking the heat exchanger equipment.

[0018] As a further improvement of the above scheme, the adjustment assembly also includes a transmission block 1, a transmission belt, a transmission block 2 and a knob. The outer wall of the upper end of the screw is connected to the transmission block 1. The transmission block 1 and the outer side of the transmission block 2 are provided with a transmission belt. The transmission belt is used to drive the transmission block 1 to rotate. The top of the transmission block 2 is connected to the knob, and the knob is used to open and close the locking mechanism of the heat exchanger equipment.

[0019] Through the above technical solution, the knob is used to drive the transmission block 2, which finally drives the transmission block 1 under the connection of the transmission belt, thereby realizing the transmission of the equipment and controlling and adjusting the limit assembly.

[0020] As a further improvement of the above scheme, the anti-loosening mechanism includes a limit bar, an adjustment block, a protrusion, a sliding groove, a slider, a limit plate and a limit slot. The limit bar is arranged between the knob and the mounting platform, the limit bar is inserted and connected to the limit slot, the limit slot is opened on the inner side of the limit plate, and the limit slot is used to limit the locking mechanism. The limit plate slides horizontally on the upper end of the mounting platform, and a slider is connected to the outer side of the limit plate. The slider is slidably connected in the sliding groove, and the sliding groove is opened on one side of the protrusion. The protrusion is rotatably connected to the upper end of the mounting platform, and the top of the protrusion is connected to the adjustment block.

[0021] Through the above technical solution, the structural characteristics of the cam of the rotating lower protrusion are utilized, so that the limit plate can be pushed to lock the limit bar under the sliding of the slider, preventing the knob from loosening and ensuring the stability of the locking mechanism.

[0023] (1) The utility model utilizes the cooperation of the anti-loosening mechanism and the locking mechanism to further stabilize the locked heat exchanger equipment, thereby preventing the locking mechanism from loosening due to vibrations generated during long-term operation of the heat exchanger equipment, ensuring the stability of the equipment during installation and use, and facilitating assembly and disassembly.

[0024] (2) The present invention utilizes the cooperation of the limit assembly and the adjustment assembly to enable the four sets of connecting vertical rods to be quickly expanded outward during installation and disassembly without affecting normal installation, and can quickly return to their vertical position and lock the heat exchanger equipment during installation.
