Description

Technical Field

[0001] The utility model relates to the technical field of a pipeline hot water delivery system, in particular to an underground thermal insulation pool. Background Art

[0002] The applicant previously applied for and submitted a patent with application number 201910362566.1, which cleverly combined the use of bathing wastewater sources with ground sources, and obtained hot water for bathing by heating the bathing wastewater in a 1:1 ratio, with good heating effect and low energy consumption. During use, it was found that the thermal insulation performance of the hot water storage tanks and bathing wastewater pools currently on trial is relatively poor, resulting in heat loss of the water in the hot water storage tanks or bathing wastewater pools. After the heat loss, the hot water temperature at the user end will not reach the set temperature, so a water tank or pool with better thermal insulation performance is needed. In addition, the limitations of ground space and the convenience of construction must be taken into account, so providing a pool with excellent thermal insulation performance is a technical problem that the field and nursing personnel urgently need to solve. It can be seen from the contents disclosed in patents with application numbers such as "2013200247857", "2013204135507", and "2017107144055" that the use of an underground insulated water tank is a relatively common technical solution for heat preservation and water storage in this field, so the technology claimed to be protected in this application is also a technical solution for an underground insulated water tank. However, since the technical solution of the present application applies the hot water or bathing wastewater storage in the technical solution with application number "201910362566.1", the water temperature is relatively not high, so the requirements for the thermal insulation performance of the underground insulation pool are higher, and the utilization of bathing wastewater is generally in residential areas, so there will be enough bathing wastewater as a heat source, and there are many underground facilities in the residential area, so there will be requirements for the floor area of ​​the underground insulation pool, which in turn requires the thickness of the thermal insulation layer used for insulation of the underground insulation pool to be as small as possible and to ensure the thermal insulation effect, so as to meet the solution of implementing the underground insulation pool in the community. Summary of the invention

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an underground heat-insulating water pool. By filling the space between the reinforced concrete tank and the water bucket with foamed polyurethane, a good heat-insulating layer is formed between the water bucket and the reinforced concrete tank, so that the water bucket becomes a heat-insulating water bucket with good heat-insulating performance. Through the function of the pad, not only the heat-insulating effect between the bottom of the water bucket and the bottom of the reinforced concrete tank can be achieved, but also the waterproof membrane at the bottom of the reinforced concrete tank can be protected from being damaged by the water bucket filled with water due to its large gravity and concentrated force application point. The reinforced concrete tank loses its waterproofing effect due to damage; the thickness of the reinforced concrete tank, the thickness of the pad and the thickness of the foamed polyurethane layer further ensure the thermal insulation performance of the water bucket; the cover plate protects the foamed polyurethane layer and the water bucket in the reinforced concrete tank; the mouth of the water bucket is flush with the top surface of the cover plate, so that the mouth of the water pipe inserted into the through hole can be directly inserted into the mouth of the water bucket, avoiding the water pipe mouth being located above the mouth of the water bucket, causing the water in the water pipe to penetrate into the foamed polyurethane layer between the through hole of the cover plate and the mouth of the water bucket, thereby affecting the thermal insulation effect.

[0004] The technical solution adopted by the utility model is:

[0005] An underground thermal insulation water pool comprises a reinforced concrete trough body, in which a water bucket is placed, a foamed polyurethane layer is filled between the inner wall of the reinforced concrete trough body and the outer wall of the water bucket, a matching cover plate is fixedly connected to the notch of the reinforced concrete trough body, a through hole matching the mouth of the water bucket is provided at the center of the cover plate, and the mouth of the water bucket extends into the through hole.

[0006] A further improvement of the utility model is that the thickness of the reinforced concrete tank body is greater than or equal to 250 mm.

[0007] A further improvement of the present invention is that the distance between the side wall of the water bucket and the groove wall of the reinforced concrete groove body is greater than or equal to 100 mm.

[0008] A further improvement of the utility model is that a pad is provided between the bottom of the reinforced concrete tank body and the bottom of the water bucket.

[0009] A further improvement of the utility model is that the pad is an extruded board.

[0010] A further improvement of the present invention is that the thickness of the pad is in the range of 60 to 100 mm.

[0011] A further improvement of the present invention is that the edge of the bucket mouth of the water bucket is flush with the top of the cover plate.

[0012] A further improvement of the utility model is that the inner wall of the reinforced concrete tank body is also provided with a waterproof membrane.

[0013] The beneficial effects of the utility model are:

[0014] First, the underground thermal insulation water pool of the utility model fills foamed polyurethane between the reinforced concrete tank body and the water bucket, so that there is a good thermal insulation layer between the water bucket and the reinforced concrete tank body, thereby making the water bucket an thermal insulation water bucket with good thermal insulation performance.

[0015] Second, the underground thermal insulation pool of the utility model can not only play a role in heat insulation between the bottom of the water bucket and the bottom of the reinforced concrete tank body through the pad, but also protect the waterproof membrane of the reinforced concrete tank bottom to avoid being damaged by the waterproof membrane at the corresponding position due to the large gravity of the water bucket and the concentrated force point, so that the reinforced concrete tank body loses its waterproof effect.

[0016] Thirdly, the underground heat-insulating water tank of the utility model further ensures the heat-insulating performance of the water bucket through the thickness of the reinforced concrete tank body, the thickness of the pad and the thickness of the foamed polyurethane layer.

[0017] Fourthly, the underground thermal insulation water pool of the utility model protects the foamed polyurethane layer and the water bucket in the reinforced concrete tank body through the function of the cover plate.

[0018] Fifth, in the underground heat-insulating water pool of the utility model, the mouth of the water bucket is flush with the top surface of the cover plate, so that the mouth of the water pipe inserted into the through hole can be directly inserted into the mouth of the water bucket, avoiding the mouth of the water pipe being located above the mouth of the water bucket, causing the water in the water pipe to penetrate into the foamed polyurethane layer between the through hole of the cover plate and the mouth of the water bucket, thereby affecting the heat-insulating effect.
