Description

Technical Field

[0001] The invention belongs to the technical field of geothermal energy extraction, and in particular relates to a geothermal energy extraction device. Background Art

[0002] At present, geothermal energy extraction devices usually use U-shaped pipes for deep burial or S-shaped pipes for shallow burial for heat exchange, or directly extract groundwater, so that the geothermal flow needs to be supported and fixed on the pipes when in use.

[0003] For example, Chinese utility model CN220706616U discloses a geothermal energy extraction device. By turning a hand wheel, the threaded rod drives the clamping block to move through a first rotating seat, and the position of the clamping block is adjusted to a position suitable for the diameter of the pipe. The pipe is placed between a left clamping ring and a right clamping ring, and then the crank is turned to make the bidirectional threaded shaft drive the left slider and the right slider to slide synchronously inward in the sliding groove, so that the left slider and the right slider drive the left clamping ring and the right clamping ring to fix and clamp the pipe.

[0004] However, the clamping blocks need to be adjusted one by one during use, which makes the operation process cumbersome and inconvenient to use. In addition, each clamping block is adjusted independently, so that the position of each clamping block cannot be accurately unified, thereby causing the clamping force on the pipeline to be uneven, affecting the clamping and fixing effect of the pipeline. Summary of the invention

[0005] The purpose of the present invention is to provide a geothermal energy extraction device, which meshes with the gear ring connected by the driving ring to synchronously drive multiple screw sleeves to rotate synchronously, so that multiple screws move axially synchronously to achieve clamping of the pipeline, thereby solving the existing inconvenience and the problem that the position of the clamping block cannot be accurately unified.

Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0036] Embodiment 1

[0037] See also Figures 1 to 3 As shown, the present invention is a geothermal energy extraction device, including a bracket 1, the bracket 1 is slidably connected to a fixed clamp ring 2, and the fixed clamp ring 2 is composed of two half rings 21. Specifically, the bracket 1 includes two beams 101, both of which are provided with sliding grooves and are rotatably connected to positive and negative screw rods 102.

[0038] Both ends of the two half rings 21 are connected with a slide seat 202 that cooperates with the slide groove, and are provided with screw holes that cooperate with the forward and reverse screw rods 102 respectively. The half ring 21 and the slide seat 202 can be an integrated structure, which is used to synchronously drive the two half rings 21 to move toward and away from each other through the rotation of the forward and reverse screw rods 102, so that the two half rings 21 separate when moving away from each other, and when moving toward each other, the end faces of the two half rings 21 can contact and be spliced ​​into a complete fixed clamp ring 2.

[0039] At the same time, the crossbeam 101 is rotatably connected to a rotating shaft 103, one end of which is fixedly connected to a rotating handle 104, and the rotating shaft 103 is transmission-connected to one end of two forward and reverse screw rods 102. The rotating shaft 103 is rotated by rotating the handle 104, and the two forward and reverse screw rods 102 are synchronously driven to rotate by the rotating shaft 103, so that the screw rod 102 synchronously drives the two half rings 21 to move, thereby improving the convenience of operation.

[0040] like Figure 4 , 7 As shown in Figures 9 to 10, the upper surface of the fixed clamp ring 2 is rotatably connected to a drive ring 3 which is coaxially arranged.

[0041] The side wall of the fixing clamp ring 2 is rotatably connected with a plurality of screw sleeves 4, and a screw rod 5 is inserted therethrough and threadedly matched with the screw sleeves 4. For example, six mounting holes 206 are provided on the inner wall of the fixing clamp ring 2, and the six mounting holes 206 are evenly distributed along the circumferential direction of the fixing clamp ring 2, and the screw sleeves 4 are rotatably connected to the inner walls of the mounting holes 206.

[0042] Among them, Figure 6 , 7 As shown in Figure 11, the outer wall of the screw sleeve 4 is fixedly connected with a gear 401, and one end of the screw rod 5 is fixedly connected with a clamping block 501, and the clamping block 501 is an arc plate structure. In addition, the screw rod 5 is provided with a limited groove 502 in the axial direction, and the fixed clamp ring 2 is fixedly connected with a key block 201 that cooperates with the limited groove 502. For example, the key block 201 is fixedly connected to the inner wall of the mounting hole 206, the screw rod 5 passes through the mounting hole 206, and the key block 201 cooperates with the limited groove 502, so that the screw rod 5 can only move axially.

[0043] like Figure 5 , 7 As shown in , 8 and 10, the drive ring 3 is fixedly connected to the gear ring 301 meshing with the gear 401, and the drive ring 3 and the gear ring 301 are respectively spliced ​​by two semi-circular rings 31 and two half gear rings 302, and the end faces of the semi-circular rings 31 and the half gear rings 302 are flush, so that the drive ring 3 and the gear ring 301 are driven by the two half rings 21 to separate into two halves and splice completely.

[0044] Specifically, Figure 8 As shown, when the drive ring 3 and the gear ring 301 rotate until the end faces are flush with the end faces of the half ring 21, the two half rings 21 can be driven to move by rotating the forward and reverse screw rods 102, and then the semi-circular ring 31 and the semi-gear ring 302 also move with the half ring 21, thereby achieving separation or complete moving splicing when fixing the pipeline.

[0045] The fixed clamp ring 2 is connected with a driving assembly, which is used to drive the driving ring 3 to rotate through the driving assembly, and use the gear ring 301 and the gear 401 to drive the six screw sleeves 4 to rotate synchronously, so as to achieve the synchronous axial movement of the six screw rods 5, thereby effectively improving the convenience of operation. In addition, each screw rod 5 moves synchronously, so that the moving position of the clamping block 501 is precisely the same, so that the clamping force on the pipeline is more balanced, which is conducive to improving the clamping and fixing effect of the pipeline.

[0046] In addition, the mounting hole 206 is a stepped hole, and the end face of the screw sleeve 4 is against the stepped surface of the mounting hole 206, the gear 401 is located on the inner side of the fixed clamp ring 2, and the gear ring 301 is fixed to the inner wall of the driving ring 3, so that the reaction generated by the clamping block 501 when clamping the pipe is transmitted to the screw sleeve 4 through the screw rod 5, and the reaction force is axially toward the outer side of the fixed clamp ring 2, and the end face of the screw sleeve 4 is against the stepped surface of the mounting hole 206, so that the support for the screw sleeve 4 can be better improved, and the stability and reliability of the rotation of the screw sleeve 4 can be improved. At the same time, a push-off bearing can also be installed between the end face of the screw sleeve 4 and the stepped surface of the mounting hole 206 to ensure the convenience of the rotation of the screw sleeve 4.

[0047] Embodiment 2

[0048] like Figure 4 , 7 As shown in , 8 and 10, on the basis of the first embodiment, the driving assembly includes a worm 203 rotatably connected to the half ring 21 through a bearing frame, and a worm gear ring 303 fixedly connected to the driving ring 3, the worm gear ring 303 is formed by splicing two semi-circular worm gear rings 304, the two semi-circular worm gear rings 304 are respectively connected to the semi-circular ring 31, and the end faces are flush, so that splicing and separation with the driving ring 3 can be achieved.

[0049] A handwheel is connected to the rotating shaft at one end of the worm 203. The worm 203 is rotated by the handwheel, and the worm 203 is meshed with the worm wheel ring 303 to drive the driving ring 3 to rotate, and then the six screw sleeves 4 are synchronously driven to rotate through the gear ring 301. The use of worm wheels for transmission also has the effect of saving labor, which makes it easy to clamp the pipeline through manual operation.

[0050] Embodiment 3

[0051] like Figure 7 and 10 As shown, on the basis of the first or second embodiment, the two half rings 21 are fixedly connected with the connecting plate 204, and the connecting plate 204 is threadedly connected with the hand screw 205. The two semicircular rings 31 are respectively provided with positioning holes 305 corresponding to the positions of the hand screws 205, which are used to achieve the position fixation of the two semicircular rings 31 through the cooperation between the hand screws 205 and the positioning holes 305.

[0052] Furthermore, after the hand screw 205 cooperates with the positioning hole 305, the end face of the semicircular ring 31 is flush with the end face of the semicircular ring 21 after being fixed in this position, so that the separation position of the semicircular ring 31 can be accurately located, and the semicircular ring 31 will not rotate accidentally after separation, thereby ensuring the stability of use, and ensuring that the position of the clamping block 501 will not change, thereby ensuring that the position of each clamping block 501 remains uniform during use.
