Description

Technical Field

[0001] The utility model relates to the technical field of underground heat exchanger construction, in particular to an auxiliary device for detecting the depth of a heat exchange hole of an underground heat exchanger. Background Art

[0002] An underground heat exchanger, also known as a geothermal heat pump or underground heat exchanger, is a device that uses underground thermal energy for air conditioning and heating. The underground heat exchanger buries pipes underground and uses the heat medium (such as water) in the pipes to exchange heat with underground soil or groundwater, thereby absorbing or releasing heat. In winter, circulating water absorbs heat from the soil and transfers the heat to the room through the heat pump system for heating; in summer, circulating water discharges indoor heat into the soil to achieve a cooling effect; during the construction process, a drilling rig is required to drill holes, and after the holes are drilled, the heat exchange hole depth detection auxiliary device is required to detect the hole depth.

[0003] The previous auxiliary device for detecting the depth of the heat exchange hole of the underground heat exchanger has the following disadvantages: 1. When detecting different heat exchange holes, the adjustment plate cannot be adjusted to the initial ground elevation, which reduces the accuracy of the depth detection of the heat exchange hole of the underground heat exchanger. Therefore, those skilled in the art provide an auxiliary device for detecting the depth of the heat exchange hole of the underground heat exchanger to solve the problems raised in the above background technology. Utility Model Content

[0004] The main purpose of the utility model is to provide an auxiliary device for detecting the depth of heat exchange holes of an underground heat exchanger, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An auxiliary device for detecting the depth of a heat exchange hole of an underground heat exchanger comprises a base, an adjustment plate, a support plate and an adjustment plate;

[0007] The top corner of the base is connected with a leveling screw through a connecting bearing, the top of the leveling screw is sleeved with a leveling nut and the top of the leveling nut is welded with an adjusting plate, the top two sides of the top of the adjusting plate are equipped with a level ruler through bolts, the top two ends of the adjusting plate are equipped with a support plate through screws, the support plates are provided with strip sliding holes, and sliding screws slide in the strip sliding holes, an adjusting plate is connected between the sliding screws through mounting holes, and a servo motor is installed at one end of the top of the adjusting plate through a mounting seat, an output shaft sleeve of the servo motor is provided with an active bevel gear, an end plate is welded on one side of the support plate, and a rotating shaft is connected between the end plates through a bearing, a winding disk is sleeved on the rotating shaft, and a measuring rope is wound on the winding disk, and a driven bevel gear is sleeved on one end of the rotating shaft and located on one side of the winding disk.

[0008] As a further solution of the utility model: a servo motor controller is installed at one end of the servo motor by means of a screw, the output end of the servo motor controller is electrically connected to the input end of the servo motor by a wire, and the servo motor controller is used to automatically control the rotation speed of the servo motor, thereby controlling the winding speed of the measuring rope.

[0009] As a further solution of the utility model: the active bevel gear and the driven bevel gear are meshed with each other.

[0010] As a further solution of the utility model: a rubber limiting sleeve is arranged on the top of the adjusting plate, a plumb bob is connected to the free end of the measuring rope and the bottom end of the plumb bob is located in the rubber limiting sleeve.

[0011] As a further solution of the utility model: a brakeable universal wheel is installed at the bottom corner of the base through bolts.

[0012] As a further solution of the utility model: the other end of the sliding screw is sleeved with a locking nut and the locking nut is located outside the strip sliding hole. Loosening the locking nut allows the sliding screw to slide in the strip sliding hole, thereby adjusting the adjustment plate to different elevations.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The brakeable universal wheel is used to facilitate the movement of the entire device to the side of the heat exchange hole after excavation. The level ruler is used to detect whether the adjustment plate is level. When it is not level enough, the adjustment plate can be leveled by rotating the leveling screws at the four corners to improve the accuracy of hole depth detection. Since the ground elevation is destroyed during the excavation process, loosen the locking nut to allow the sliding screw to slide in the strip sliding hole. Use an external elevation measuring device to slide the adjustment plate to the initial ground elevation, then remove the measuring rope and plumb bob on the winding reel to measure the depth of the heat exchange hole after drilling, thereby measuring the hole depth.

[0015] 2. When detecting different heat exchange holes, the adjustment plate can be adjusted to the initial ground elevation, which greatly improves the accuracy of the depth detection of the heat exchange holes of the buried heat exchanger. After the detection is completed, the servo motor power is turned on, and the servo motor is used to drive the active bevel gear to rotate. Since the active bevel gear and the driven bevel gear are engaged with each other, the winding disk is driven to rotate, and the measuring rope is automatically reeled up. The degree of automation is high, saving manpower and material resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Among them, a servo motor controller 13 is installed at one end of the servo motor 15 by a screw, and the output end of the servo motor controller 13 is electrically connected to the input end of the servo motor 15 through a wire; the servo motor controller 13 is used to automatically control the rotation speed of the servo motor 15, thereby controlling the winding speed of the measuring rope 22.

[0024] The driving bevel gear 16 and the driven bevel gear 17 are meshed with each other. Since the driving bevel gear 16 and the driven bevel gear 17 are meshed with each other, the winding drum 18 is driven to rotate.

[0025] Among them, a rubber limiting sleeve 5 is arranged on the top of the adjusting plate 3, the free end of the measuring rope 22 is connected to a plumb bob 6 and the bottom end of the plumb bob 6 is located in the rubber limiting sleeve 5; the rubber limiting sleeve 5 is used to limit the plumb bob 6.
