Description

Technical Field

[0001] The utility model relates to the field of ground source heat pump drilling equipment, in particular to ground source heat pump drilling equipment used in mudstone areas. Background Art

[0002] Ground source heat pump is a cutting-edge energy utilization technology. Its core lies in the use of shallow geothermal energy for heating and cooling. This system is mainly composed of underground circulation pipes, groundwater wells and indoor and outdoor units. Through the circulation pipes, the refrigerant in the indoor and outdoor units can be heated or cooled in the underground heat exchanger, thereby achieving the effect of heating or cooling. In the process of laying underground circulation pipes, in order to more efficiently utilize underground thermal energy, drilling equipment is usually used to assist and ensure that the pipes go deep underground to a sufficient depth, so as to make full use of the more stable and abundant thermal energy resources underground.

[0003] When the existing drilling equipment is working, it mainly realizes the underground drilling operation by driving the drill rod to rotate. In order to improve the stability of the drill rod during the drilling process, two flippable movable plates are usually set on the drilling equipment, and arc-shaped through holes are opened on the surfaces of the movable plates to allow the drill rod to pass through, thereby limiting the movement range of the drill rod and preventing it from shaking left and right during the drilling process. When the drill rod moves up and down inside the through hole, the outside of the drill rod will come into contact with the inside of the through hole, thereby generating friction. When the drill rod moves up, the friction may cause the movable plate to flip over, causing the position of the drill rod in the through hole to change, affecting the stability of the drill rod.

[0004] Therefore, it is necessary to provide a new ground source heat pump drilling equipment for mudstone areas to solve the above technical problems. Utility Model Content

[0014] Compared with the related art, the ground source heat pump drilling equipment for mudstone areas provided by the utility model has the following beneficial effects:

[0026] The elastic member is a spring 8, one end of the spring 8 is fixedly connected to one side of the limiting rod 5 located in the fixing groove 6, and the other side of the spring 8 is fixedly connected to the inner side of the fixing groove 6. The stable structure is composed of two clamping assemblies 2 with the same structure. The two clamping assemblies 2 are respectively fixedly arranged on the surface of the drilling device, and the two clamping assemblies 2 are arranged opposite to each other. The clamping assembly 2 includes a movable plate 9, a clamping member, two fixed columns 10 and two movable columns 11. The outer sides of the two fixed columns 10 are respectively fixed to the surface of the drilling device, and the two fixed columns 10 are internally provided with mounting grooves 12 matching the movable columns 11. The two movable columns 11 are respectively located in the mounting grooves 12 opened by the two fixed columns 10, and the movable columns 11 can rotate in the mounting grooves 12. The two ends of the movable plate 9 are respectively fixedly connected to one end of the two movable columns 11. The surface of the movable plate 9 is provided with a through hole 13 for limiting the drill rod 1, and one end of the clamping member is fixedly connected to the inner side of the through hole 13.

[0027] A pull rod 14 for flipping is arranged on the top of the movable plate 9, and the clamping member includes a spring 15 and a clamping plate 16. One end of the spring 15 is fixedly connected to the inner side of the through hole 13, and the other end of the spring 15 is fixedly connected to the outer side of the clamping plate 16. The clamping plate 16 is arranged in an arc shape. Through the mutual cooperation of the two clamping plates 16, the outer side of the drill rod 1 is clamped and limited.

[0028] The drilling device includes a support frame 17, a lifting mechanism, a motor 18 and a motor 2 19. The motor 18 is fixed inside the support frame 17, and the output end of the motor 18 is fixedly connected to one end of the lifting mechanism. The motor 2 19 is fixed to one side of the lifting mechanism, and the output end of the motor 2 19 is fixedly connected to the drill pipe 1. The lifting mechanism consists of a turntable 20, a pull rope 21 and a lifting plate 22. One side of the turntable 20 is fixedly connected to the output end of the motor 18, and the pull rope 21 is wound around the surface of the turntable 20. The other end of the pull rope 21 is fixedly connected to the top of the lifting plate 22. The turntable 20 is rotated by the rotation of the motor 18, so as to control the contraction and extension of the pull rope 21. The lifting plate 22 and the motor 2 19 are driven to move up and down by the pull rope 21, and the drill pipe 1 is rotated by driving the motor 2 19, so as to perform drilling work on the bottom surface. The motor is an AC motor with a simple structure, convenient maintenance, and reliable operation. It is suitable for drilling devices with heavy loads.

[0029] The working principle provided by the utility model is as follows: when the drill rod 1 needs to be limited, the pull rod 14 is pulled, so that the pull rod 14 drives the movable plate 9 to move, and when the movable plate 9 moves, the two movable columns 11 are driven to rotate inside the mounting groove 12, so that the movable plate 9 is turned over. After the movable plate 9 is turned over, because the clamping plate 16 is arranged in an arc shape, the outer side of the drill rod 1 is clamped and limited by the mutual cooperation of the two clamping plates 16. At the same time, the clamping plate 16 can be extended and retracted by the spring 2 15, so that it can clamp drill rods 1 of different models, which is convenient for use. Under the elastic action of the spring 2 15, a certain extrusion force can be applied to the surface of the drill rod 1 by the clamping plate 16, so as to further ensure the stability of the drill rod 1. Because the inner side of the clamping plate 16 is only in contact with the outer side of the drill rod 1, it does not affect the rotation of the drill rod 1.

[0030] When the movable plate 9 is flipped, one end of the pull rod 14 will contact the top of the limit rod 5. Because the top of the limit rod 5 is inclined, when one end of the pull rod 14 contacts the top of the limit rod 5, it will push the limit rod 5 to move inside the fixed groove 6 and squeeze the spring 1 8, so that the pull rod 14 can slide along the side of the limit rod 5 where the slot 7 is opened. When the pull rod 14 moves to the position of the slot 7, under the elastic action of the spring 1 8, the limit rod 5 can be driven to reset, thereby limiting one end of the pull rod 14 through the slot 7, so that the movable plate 9 will not be flipped due to friction during the up and down movement of the drill rod 1.

[0031] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0032] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
