[0002] The integrated photovoltaic-storage-charging prefabricated cabin is a comprehensive energy device that integrates photovoltaic power generation, energy storage, and charging functions. In the integrated photovoltaic-storage-charging prefabricated cabin system, the buried heat exchange pipe is an auxiliary technology combined with the prefabricated cabin heat dissipation and temperature control system. It is mainly used to achieve efficient heat dissipation or heat preservation of the equipment inside the prefabricated cabin by utilizing the stable temperature characteristics of the ground source (soil, groundwater, etc.), ensuring that core equipment such as photovoltaic inverters, energy storage batteries, and charging pile control modules operate at suitable temperatures.

[0003] The existing technology has the following problems: When laying existing trenchless buried heat exchange pipes, the buried heat exchange pipes need to be moved straight and smoothly into the holes. However, in actual operation, the buried heat exchange pipes may be deviated due to the inner wall of the hole or other external factors, which will affect the burial operation of the buried heat exchange pipes. Utility Model Content

[0004] The main purpose of this utility model is to provide a trenchless laying device for the buried heat exchange pipe of the integrated photovoltaic storage and charging prefabricated cabin, which can effectively solve the problem of mutual contact between the buried heat exchange pipe and the inner wall of the aperture.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A device for laying underground heat exchange pipes in a prefabricated photovoltaic storage and charging integrated cabin without excavation includes a housing, a fixing frame fixedly connected to the right side of the housing, rollers rotatably connected to the front and rear sides of the housing and the fixing frame, a plurality of rectangularly distributed limiting mechanisms fixedly connected to the inner side of the housing, a laying mechanism fixedly connected to the lower side of the fixing frame, and a lifting frame fixedly connected to the upper side of the housing and the fixing frame. The laying mechanism includes a frame, with several rectangularly distributed fourth telescopic rods fixedly connected to the upper side of the frame. The upper side of the fourth telescopic rods is fixedly connected to the lower side of the fixed frame. Several laterally distributed guide components are slidably or hingedly installed on the lower side of the frame. Limiting components are fixedly connected to the lower side of the fixed frame away from the outer shell of the mechanism.

[0006] Preferably, the limiting mechanism includes a first telescopic rod, the movable end of which is fixedly connected to a first rotating frame, and the inner side of the first rotating frame is rotatably connected to a clamping wheel.

[0007] Preferably, a second telescopic rod is rotatably connected to the side of the first telescopic rod away from the first rotating frame, the outer side of the second telescopic rod is fixedly connected to the inner side of the mechanism housing, and a third telescopic rod is rotatably connected to the upper side of the first telescopic rod, the upper side of the third telescopic rod being rotatably connected to the inner side of the mechanism housing.

[0008] Preferably, the guiding assembly includes a mechanism platform, the upper side of which is slidably or hingedly mounted on the lower side of the mechanism frame. Two movable frames are slidably connected to the lower side of the mechanism platform, and the bottom of each of the two movable frames is rotatably connected to a pressing wheel. Two fifth telescopic rods distributed in the front and rear are fixedly connected to the upper side of the mechanism platform, and the ends of the fifth telescopic rods that are far apart from each other are fixedly connected to the vertical plates on the opposite sides of the movable frames.

[0009] Preferably, the upper side of the mechanism platform is fixedly connected to two front and rear mounting frames, and a seventh telescopic rod is rotatably connected between the upper sides of two adjacent mounting frames.

[0011] Preferably, rubber pads are fixedly connected to the outer sides of the clamping wheel, the extrusion wheel, and the guide roller.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides a trenchless laying device for buried heat exchange pipes in a prefabricated photovoltaic-storage-charging integrated cabin. Based on the cooperation of a limiting mechanism, a first telescopic rod, a first rotating frame, clamping wheels, a second telescopic rod, and a third telescopic rod, the buried heat exchange pipe is pushed forward stably and straight by passing through the limiting mechanism and being squeezed by the clamping wheels. This avoids the lack of guiding measures for the buried heat exchange pipe, which would make it susceptible to other influences during the burial operation, causing the buried heat exchange pipe to deviate or bend, thus affecting the burial operation.

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figures 1-6 As shown, a ground-buried heat exchange pipe laying device for a prefabricated photovoltaic storage and charging integrated cabin includes a housing 1, a fixing frame 2 fixedly connected to the right side of the housing 1, rollers 3 rotatably connected to the front and rear sides of the housing 1 and the fixing frame 2, a number of rectangularly distributed limiting mechanisms 4 fixedly connected to the inner side of the housing 1, a laying mechanism 5 fixedly connected to the lower side of the fixing frame 2, and a lifting frame 6 fixedly connected to the upper side of the housing 1 and the fixing frame 2. The laying mechanism 5 includes a mechanism frame 51. Several rectangularly distributed fourth telescopic rods 52 are fixedly connected to the upper side of the mechanism frame 51. The upper side of the fourth telescopic rods 52 is fixedly connected to the lower side of the fixed frame 2. Several horizontally distributed guide components 53 are slidably installed on the lower side of the mechanism frame 51. A limit component 54 is fixedly connected to the lower side of the fixed frame 2 away from the mechanism housing 1.

[0017] It should be noted that the outer casing 1 is used to house various electrical components, control modules, etc., to facilitate external control of the equipment. The internal structure is equipped with a counterweight, or the external counterweight is used for stability during use. During the burial operation, two of these devices work together, with the laying mechanisms 5 of the two devices located on opposite sides and being pulled into the hole. The fourth telescopic rod 52 is an electric push rod that can drive the frame 51 to move up and down. The guide component 53 is used to guide the buried heat exchange pipe, and the limiting component 54 is used to limit the buried heat exchange pipe.

[0018] like Figure 3 As shown, the limiting mechanism 4 includes a first telescopic rod 41, the movable end of the first telescopic rod 41 is fixedly connected to a first rotating frame 42, and the inner side of the first rotating frame 42 is rotatably connected to a clamping wheel 43.

[0019] It should be noted that the first telescopic rod 41 is an electric push rod. The first telescopic rod 41 drives the first rotating frame 42 to move, so that the clamping wheel 43 limits the outer wall of the buried heat exchange pipe. The clamping wheel 43 is used to enable the buried heat exchange pipe to move straight and smoothly. The first rotating frame 42 is equipped with a power component for driving the clamping wheel 43 to rotate.

[0020] like Figure 3 As shown, a second telescopic rod 44 is rotatably connected to the side of the first telescopic rod 41 away from the first rotating frame 42. The outer side of the second telescopic rod 44 is fixedly connected to the inner side of the mechanism housing 1. A third telescopic rod 45 is rotatably connected to the upper side of the first telescopic rod 41. The upper side of the third telescopic rod 45 is rotatably connected to the inner side of the mechanism housing 1.

[0021] It should be noted that the second telescopic rod 44 and the third telescopic rod 45 are electric push rods, which can control their own length and thus adjust the position and posture of the clamping wheel 43.

[0022] like Figure 5 , Figure 6 As shown, the guide assembly 53 includes a mechanism platform 531. The upper side of the mechanism platform 531 is movably mounted on the lower side of the mechanism frame 51. Two movable frames 532 are slidably connected to the lower side of the mechanism platform 531. Each of the two movable frames 532 is rotatably connected to a pressing wheel 533 at its bottom. Two fifth telescopic rods 534 are fixedly connected to the upper side of the mechanism platform 531. The ends of the fifth telescopic rods 534 that are far apart from each other are fixedly connected to the vertical plates on the far apart sides of the movable frames 532. A pressure sensor is provided on the pressing wheel 533. The guide assembly 53 is controlled by the control device inside the mechanism housing 1. The pressure sensor only needs to detect the magnitude of the pressure and does not need to detect the precise value.

[0023] It should be noted that the fifth telescopic rod 534 is an electric push rod that can control its own length, thereby causing the fifth telescopic rod 534 to drive the moving frame 532 to move, so that the extrusion wheel 533 clamps the buried heat exchange pipe. With the cooperation of multiple sets of guide components 53, the buried heat exchange pipe is guided to avoid it from deviating, and it can also be corrected when the buried heat exchange pipe is bent.

[0024] like Figure 5 , Figure 6 As shown, two mounting frames 535 are fixedly connected to the upper side of the mechanism platform 531, and a seventh telescopic rod 55 is rotatably connected between the upper sides of the two adjacent mounting frames 535.

[0025] It should be noted that the mechanism platform 531 located near the outer shell 1 is fixed on the mechanism frame 51, and the other mechanism platforms 531 are rotatably connected to the mechanism frame 51. When the buried heat exchange tube undergoes a large skew bend, the seventh telescopic rod 55 will drive the mechanism platform 531 to rotate, preventing the linearly moving extrusion wheel 533 from being subjected to large lateral pressure. The coordinated cooperation of multiple guide components 53 is used to stabilize the state of the buried heat exchange tube.

[0026] like Figure 5 As shown, the limiting component 54 includes a sixth telescopic rod 541. The upper side of the sixth telescopic rod 541 is fixedly connected to the lower side of the fixed frame 2 away from the outer shell 1 of the mechanism. The lower side of the sixth telescopic rod 541 is fixedly connected to a second rotating frame 542. The inner side of the second rotating frame 542 is rotatably connected to a guide roller 543.

[0027] It should be noted that the sixth telescopic rod 541 is an electric push rod that can drive the second rotating frame 542 to move up and down, so that the second rotating frame 542 presses on the guide roller 543 to prevent the buried heat exchange pipe from tilting upwards.

[0028] like Figures 3-6 As shown, rubber pads are fixedly connected to the outer sides of the clamping wheel 43, the extrusion wheel 533, and the guide roller 543.

[0029] It should be noted that the rubber pad can increase the friction between the clamping wheel 43, the extrusion wheel 533 and the guide roller 543 and the buried heat exchange pipe, while avoiding rigid contact, which could lead to the problem of the buried heat exchange pipe being squeezed and deformed.

[0030] The working principle of this utility model is as follows: First, the first telescopic rod 41 is an electric push rod. The first telescopic rod 41 drives the first rotating frame 42 to move, causing the clamping wheel 43 to limit the outer wall of the buried heat exchange pipe. The clamping wheel 43 ensures the smooth and stable movement of the buried heat exchange pipe. The first rotating frame 42 is equipped with a power component to drive the clamping wheel 43 to rotate. The second telescopic rod 44 and the third telescopic rod 45 are electric push rods. Their lengths can be controlled to adjust the position and orientation of the clamping wheel 43, thereby facilitating the movement of the buried heat exchange pipe. The pipe passes through the limiting mechanism 4, and under the mutual squeezing of the clamping wheels 43, the buried heat exchange pipe can be pushed forward stably and straight. This avoids the lack of guiding measures for the buried heat exchange pipe, which would make it susceptible to other influences during the burial operation, causing the buried heat exchange pipe to deviate or bend, affecting the burial operation. Finally, during the burial operation, two devices work together, with the laying mechanisms 5 of the two devices on opposite sides and being pulled into the hole. The fourth telescopic rod 52 is an electric push rod that can drive the mechanism frame 51 to move up and down. The guide assembly 53 is used to guide the buried heat exchange pipe. The guide and limiting component 54 is used to limit the buried heat exchange pipe. The fifth telescopic rod 534 is an electric push rod that can control its own length, thereby causing the fifth telescopic rod 534 to drive the moving frame 532 to move, so that the extrusion wheel 533 clamps the buried heat exchange pipe. Relying on the cooperation of multiple sets of guide components 53, the buried heat exchange pipe is guided to avoid its deflection. At the same time, it can be corrected when the buried heat exchange pipe is bent. The mechanism platform 531 located near the mechanism housing 1 is fixed on the mechanism frame 51, and the other mechanism platforms 531 are rotatably connected to the mechanism frame 51. When the buried heat exchange pipe undergoes significant skew or bending, the seventh telescopic rod 55 will drive the mechanism platform 531 to rotate, preventing the linearly moving extrusion roller 533 from being subjected to excessive lateral pressure. Multiple guide components 53 work together to stabilize the state of the buried heat exchange pipe. The limit component 54 presses down on the buried heat exchange pipe, and the guide component 53 limits the buried heat exchange pipe. This ensures that if the buried heat exchange pipe undergoes an accidental operation that causes a rapid and significant skew, it can be immediately stabilized by the guide component 53, thus controlling the skew of the buried heat exchange pipe and facilitating subsequent manual maintenance operations.
