[0001] The utility model relates to the technical field of ground source heat pump pipe protection under foundation pits, in particular to a device for fixing and protecting the solid soil area of ​​horizontal pipes and vertical pipes of ground source heat pumps under foundation pits. Background Art

[0002] Ground source heat pumps use underground soil or groundwater as heat or cold sources, and use their relatively constant temperature characteristics to convert low-temperature energy into high-temperature heat or low-temperature cold energy to meet the needs of heating, cooling and hot water in buildings. This technology reduces the dependence on fossil fuels in traditional heating and cooling methods, and reduces energy consumption and environmental pollution.

[0003] When the vertical pipe of the ground source heat pump under the foundation pit climbs out of the foundation raft, there is usually no available building to fix the buried pipe in the solid soil area, and the climbing height is relatively high. The pipe is easily damaged when the earth is backfilled at the installation position of the pipe. In order to solve the above problems, the utility model patent proposes a device for fixing and protecting the vertical pipe of the ground source heat pump under the foundation pit in the solid soil area. Utility Model Content

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Example 1, please refer to Figure 1-7In the embodiment of the utility model, a device for fixing and protecting the horizontal pipe and vertical pipe of a ground source heat pump in a foundation pit is provided. The device supports and fixes a plurality of support pipes 100 on the ground outside the basement. A fastening frame 200 is installed and fixed at equal intervals on the outside of the plurality of support pipes 100. A plurality of parallel heat pump pipes 300 are fixedly inserted and fixed inside the fastening frame 200. The fastening frame 200 includes a plurality of pipe joints 210 respectively sleeved and fixed with the support pipes 100 at corresponding positions. A limit pipe 220 is inserted and fixed between two relatively arranged pipe joints 210. A limit pipe 220 is inserted and fixed between two adjacent pipe joints 210. There is a connecting pipe 230, a limiting pipe 240 is inserted and fixed between the two connecting pipes 230, the heat pump pipe 300 is arranged between the limiting pipe 1 220 and the limiting pipe 240, and a protective mechanism 400 for protecting the heat pump pipe 300 is detachably sleeved and fixed between two adjacent fastening frames 200. The protective mechanism 400 includes a bamboo plywood 1 410, a bamboo plywood 2 420, a bamboo plywood 3 430 and a bamboo plywood 440 that are hinged to each other. The bamboo plywood 1 410, the bamboo plywood 2 420, the bamboo plywood 3 430 and the bamboo plywood 440 are enclosed to form a rectangular protective frame structure.

[0026] Specifically, by fixing the support pipe 100 in the basement foundation pit, a fixed fastening frame 200 is installed between multiple support pipes 100, and the limiting pipe 1 220 and the limiting pipe 240 on the fastening frame 200 restrain and fix multiple parallel heat pump pipes 300. At the same time, multiple bamboo plywoods are sleeved and fixed on the outer side of the heat pump pipe 300. The multiple bamboo plywoods form a rectangular frame structure, which helps to protect the heat pump pipe 300 and solve the problem of climbing, fixing and protecting the horizontal pipes and vertical pipes of the heat pump pipe 300 in the solid soil area under the foundation pit.

[0027] like Figure 3 As shown, in this embodiment, a rubber-plastic insulation pipe 310 is sleeved and fixed on the outer side of the heat pump pipe 300, and the outer side of the rubber-plastic insulation pipe 310 is tightly wrapped with a rubber-plastic tape.

[0028] In this embodiment, the ground source heat pump pipe 300 includes a horizontal pipe and a vertical pipe. When the horizontal pipe is laid out of the foundation raft vertical pipe, the vertical pipe is divided into two groups according to supply and return water. Each group contains multiple heat pump pipes 300. The heat pump pipe 300 is wrapped with a rubber-plastic insulation pipe 310 on the outside to play a heat preservation role, and is tightly wrapped with a rubber-plastic tape to buffer the heat pump pipe 300 on the support fastening frame 200. The vertical pipe can be fixed to the limiting pipe 220 with iron wire. According to the climbing height of the vertical pipe, the height of the erection fixing device is determined, and the support pipe 100 of the appropriate height is selected to match the fastening frame 200 for installation.

[0029] like Figure 5 As shown, in this embodiment, sleeves are fixed in multiple directions on the top and bottom, front and rear sides, left and right sides of the pipe joint 210, and the connecting pipe 230, the limiting pipe 1 220 and the limiting pipe 2 240 are all plugged and fixed with the sleeves at the corresponding positions.

[0030] In this embodiment, sleeves are preset in multiple directions on the outer side of the pipe joint 210, so that when installing the fixing device, the support pipe 100, the first limiting pipe 220, the second limiting pipe 240, and the connecting pipe 230 can all be inserted and installed on the pipe joint 210. The required components for fixing are simple and commonly used, and the erection is convenient.

[0031] As Figure 6 and Figure 7 shown, in this embodiment, one side of the first bamboo plywood 410 is hinged to the second bamboo plywood 420, the side of the second bamboo plywood 420背离 the first bamboo plywood 410 is hinged to the third bamboo plywood 430, and the side of the third bamboo plywood 430背离 the second bamboo plywood 420 is hinged to the fourth bamboo plywood 440.

[0032] In this embodiment, during the installation of multiple bamboo plywoods, when taking one bamboo plywood, the bamboo plywoods in other positions will be taken out together, which is convenient for simultaneously sleeving multiple bamboo plywoods on the outer side of the heat pump pipe 300.

[0033] As Figure 6 shown, in this embodiment, a U-shaped clamping plate 450 is sleeved on the outer sides of the first bamboo plywood 410, the second bamboo plywood 420, the third bamboo plywood 430, and the fourth bamboo plywood 440. Screws 451 are detachably fixed between the first bamboo plywood 410, the second bamboo plywood 420, and the fourth bamboo plywood 440 and the U-shaped clamping plate 450.

[0034] In this embodiment, after multiple bamboo plywoods are initially sleeved and fixed on the outer side of the heat pump pipe 300, the U-shaped clamping plate 450 is clamped and sleeved between the first bamboo plywood 410 and the third bamboo plywood 430, and then the U-shaped clamping plate 450 is fixed to the first bamboo plywood 410 and the second bamboo plywood 420 by using the screws 451, so as to firmly fix the bamboo plywood to the outer side of the heat pump pipe 300 by using the U-shaped clamping plate 450. At the same time, the U-shaped clamping plate 450 also protects the outer side of the U-shaped insertion plate 412, playing a role in protecting the connection positions of multiple bamboo plywoods.

[0035] It should be noted that there may be some inaccuracies in the translation due to the lack of clear context for some terms. For example, "背离" is translated as "背离" here, and it may need to be adjusted according to the actual situation.During specific implementation, first, fix the two support pipes 100 to the foundation pit ground, then sleeve and install the fixed pipe joint 210 on the support pipe 100, insert and fixedly connect the connecting pipe 230 between two adjacent pipe joints 210, insert and fix the first limiting pipe 220 on the pipe joint 210, insert and fix the second limiting pipe 240 on the connecting pipe 230. Then, install the heat pump pipe 300 between the first limiting pipe 220 and the second limiting pipe 240 from the ends of the first limiting pipe 220 and the second limiting pipe 240 that are背离 the connecting pipe 230. Then, install another connecting pipe 230 at the ends of the first limiting pipe 220 and the second limiting pipe 240 that are背离 the connecting pipe 230, and install two other pipe joints 210 at both ends of the connecting pipe 230. Finally, insert the other two support pipes 100 into these two pipe joints 210 to support and fix multiple heat pump pipes 300. Finally, sleeve and install multiple bamboo glue boards outside the heat pump pipe 300 to protect the heat pump pipe 300.

[0036] Embodiment 2, on the basis of Embodiment 1, in order to quickly sleeve and install multiple bamboo glue boards outside the heat pump pipe.

[0037] As Figure 7 shown, in this embodiment, a first jack 411 is opened in the middle of one side of the first bamboo glue board 410, a second jack 441 is opened in the middle of one side of the fourth bamboo glue board 440, and a U-shaped insertion plate 412 is detachably inserted and fixed between the first jack 411 and the second jack 441.

[0038] Specifically, after sleeving multiple bamboo glue boards outside the heat pump pipe 300, the U-shaped insertion plate 412 can be inserted between the first jack 411 and the second jack 441, and the first bamboo glue board 410 and the fourth bamboo glue board 440 are fixed together by using the U-shaped insertion plate 412, so as to preliminarily fix multiple bamboo glue boards outside the heat pump pipe 300.

[0039] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0040] It should be noted that there is an unclear expression "背离" in the original text. I translated it as "背离" as accurately as possible according to the context, but it may need to be further determined according to the specific technical content.In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
