Description

Technical Field

[0001] The utility model relates to the technical field of anti-floating devices, in particular to an anti-floating device for buried pipes of a ground source heat pump automatic control system. Background Art

[0002] A ground source heat pump uses ground source energy (soil, groundwater, surface water, low-temperature geothermal water, and tail water) as the cooling source for summer refrigeration of the heat pump and the low-temperature heat source for winter heating, and is also a system for realizing heating, refrigeration, and domestic hot water. Modern ground source heat pumps mainly rely on buried pipes for the transportation of fluids. The buried pipes are buried underground. Due to the buoyancy of groundwater, it will cause certain difficulties in pipe laying. Moreover, since the water contains a large amount of sediment, the sediment deposition will reduce the effective depth in the hole. Therefore, at present, the anti-floating of buried pipes mainly uses the method of pressing the pipes with sandbags. However, this anti-floating method requires a large number of counterweight bags, which is inconvenient for construction, and the middle connecting belt of the counterweight bags is easily broken, resulting in the loss of counterweight. In view of this, in-depth research on the above problems has led to the generation of this case. Content of the Utility Model

Based on the embodiments of 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.

[0020] Please refer to Figures 1-3 , the present utility model provides an implementation scheme: In order to prevent the buried pipes of the ground source heat pump from floating and avoid the problem of the connection belt breaking caused by using counterweight sandbags, the present application discloses a ground source heat pump automatic control system buried pipe anti-floating device.

The middle section of the anti-floating strip 1 is a ring sleeve with a semi-circular structure. The anti-floating strip 1 is a long strip-shaped plate with a rectangular cross-section. The anti-floating strip 1 is horizontally supported outside the pipe, and at the same time, the semi-circular ring sleeve of the anti-floating strip 1 is used to hold the pipe, playing a limiting role. On one side of the anti-floating strip 1 and the anti-floating strip 1, there is an anti-floating block 2, and the anti-floating block 2 is used to connect adjacent anti-floating strips 1. At both ends of the anti-floating strip 1, a pair of chutes 3 are opened, and a pair of sliders 4 are assembled in the pair of chutes 3.

At the bottom ends of the two pairs of positioning rods 8, a pair of anti-floating counterweight blocks 9 are respectively connected. At the top ends of the two pairs of positioning rods 8, two pairs of positioning nuts 10 are threadedly connected. By setting the two pairs of positioning rods 8 and a pair of anti-floating counterweight blocks 9, a downward force is applied to the anti-floating strip 1, thereby playing an anti-floating role for the pipe. The anti-floating counterweight block 9 is made of precast concrete blocks, which is convenient for production and has a long service life;

[0025] As a preferred solution, furthermore, a pair of clamping grooves 6 are a pair of arc-lacking annular clamping grooves 6, which cooperate with the annular area of the anti-floating clamping strip 1, playing the role of squeezing and positioning the anti-floating clamping strip 1 and preventing the anti-floating clamping strip 1 from moving axially.
