BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0012] Figure 1 It is a structural schematic diagram of the buried pipe limiting device of the ground source heat pump of the utility model. DETAILED DESCRIPTION

[0013] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0014] In the description of the utility model, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0015] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0016] In the utility model, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0017] like Figure 1 As shown, the utility model provides a ground source heat pump buried pipe limiting device, including: a limiting plate 1 and an end piece 2, the two ends of the limiting plate 1 are respectively fixedly connected to the end piece 2, the end piece 2 mainly functions to prevent the limiting plate 1 from overturning, the limiting plate 1 is provided with a hole array 11, the holes on the hole array 11 are used to pass through the ground source heat pump drainage pipe, the end piece 2 has a vertical retaining surface on the outer side, and the retaining surface abuts against the side wall of the pipe trench, thereby preventing the limiting plate from overturning.

[0018] The utility model provides a ground source heat pump buried pipe limiting device, and a limiting plate has a hole array, so that the device has the effect of separate placement, and a large number of ground source heat pump buried pipes are limited to be laid in a uniform and neat arrangement through the hole array, thereby avoiding the occurrence of traditional laying with loose fixation, displacement and misalignment.

[0019] A further improvement is that a sleeve 3 is fixed in each hole on the limiting plate 1 by gluing, and the length of the sleeve 3 is longer than the length of the hole. The longer sleeve 3 is used to limit the buried pipe of the ground source heat pump in a certain length direction to make it more regular.

[0020] In order to provide better support for the end piece 2, the technical solution is further improved as follows: the end piece 2 includes a retaining plate 21 and an extension portion 22. The retaining plate 21 is vertically arranged to abut against the inner wall of the trench for support. The extension portion 22 is fixedly connected to the inner side of the retaining plate 21 and has a vertical surface that provides a mounting surface for the connection of the limit plate. The retaining plate 21 and the extension portion 22 are connected in a T-shape.

[0021] In order to make the end piece more stable and further prevent the limit plate from overturning or tilting, the technical solution is further improved in that the retaining plate 21 and the lower end of the extension 22 are fixedly connected with a bearing seat 23, and the lower surface of the bearing seat 23 is a plane, which is used to sit stably on the bottom surface of the trench, thereby improving the stability of the end piece. At the same time, the end piece, through the retaining plate and the bearing seat, plays a role in preventing the side cover from overturning and the settlement of the pipeline due to uneven force when laying the pipeline.

[0022] Further improvement is that the retaining plate 21 is connected to the bearing seat 23 in an L-shape. The retaining plate 21 and the bearing seat 23 can be integrally formed, or the retaining plate, the bearing seat and the extension part can be connected in different ways according to the material, such as gluing, welding, bolting, dovetail groove clamping and the like.

[0023] In order to avoid the situation that the two sides of the device may not be able to be tightly pressed against the side walls of the trench, and thus the device is prone to displacement when installing the buried pipe of the ground source heat pump, in order to avoid this problem, the technical solution is further improved as follows: the extension part 22 and / or the limit plate 1 are provided with a waist-shaped hole 4, and the extension part 22 and the limit plate 1 are connected by bolts passing through the waist-shaped hole 4. The overall length of the device can be adjusted through the waist-shaped hole. When the device is placed in the trench, the overall length can be adjusted to make the device and the side walls of the trench tightly pressed against each other, and the device can flexibly adjust the support distance according to different trench widths, meeting the function of flexibly adjusting the support.

[0024] The limiting plate 1 and the end piece 2 are preferably made of epoxy resin material, which has the advantages of acid and alkali resistance, corrosion resistance and long service life.

[0025] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
