Description

Technical Field

[0001] This utility model relates to the field of surface water detection technology, specifically to a high-efficiency heat preservation and storage device for surface water detection. Background Technology

[0002] Surface water testing can promptly assess water quality, including indicators such as pH, dissolved oxygen, and heavy metal content, determining whether it meets water quality standards for different uses such as drinking water, irrigation water, and industrial water, providing a basis for the rational development and utilization of water resources. Simultaneously, long-term monitoring can reveal trends in surface water quality changes, promptly identifying water pollution problems, providing data support for water environment protection and pollution control, and ensuring the stability of ecosystems and human health and safety. During surface water testing operations, water samples need to be properly stored to preserve water quality and improve testing accuracy. However, existing storage equipment is often structurally simple and lacks the ability to effectively insulate surface water, affecting test results.

[0003] As disclosed in CN211309550U, a surface water testing storage device with heat preservation function includes an outer casing, a water storage tank, and an inner casing. A vacuum glass is fixedly connected to the outer surface of the inner cavity of the outer casing. A novel space-reflective heat-insulating coating is connected to the outer surface of the inner casing using an acrylic adhesive. An aerogel felt is placed between the novel space-reflective heat-insulating coating and the vacuum glass. Heating pipes are fixedly connected to the lower ends of both sides of the inner cavity of the inner casing. This invention achieves the requirement of heat preservation function through the functions of the vacuum glass, a first sealing plate, a first temperature sensor, aerogel felt, novel space-reflective heat-insulating coating, PLC controller, second temperature sensor, heating pipes, and a second sealing plate. It solves the problem that existing storage devices lack heat preservation function, and changes in surface water temperature lead to changes in water quality, resulting in inaccurate test results.

[0004] However, when heating the water storage tank, this utility model mainly heats the air inside the inner tank through an electric heating tube, achieving air heat conduction heating. This method has low heating efficiency and poor heating uniformity, and can also easily cause the air inside the inner tank to expand, posing a safety hazard. To address this, we propose a high-efficiency thermal insulation storage device for surface water detection. By using silicone oil heat conduction, we solve the problems of low heating efficiency, insufficient heating uniformity, and safety issues of this utility model, thus improving its practical effect and ease of use.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0022] A high-efficiency thermal insulation storage device for surface water detection includes an insulated box 100, a storage beaker 101 inside the insulated box 100, a constant temperature heating mechanism outside the storage beaker 101, and a polyurethane foam insulation layer 102 outside the constant temperature heating mechanism.

[0023] The above solution effectively prevents heat loss from the equipment by setting a polyurethane foam insulation layer 102 on the outside of the constant temperature heating mechanism, thus achieving the effect of heat preservation.

[0024] In this embodiment, preferably, the constant temperature heating mechanism includes a heating chamber 200, an electric heating tube 201 and a temperature sensor 202 are fixedly installed inside the heating chamber 200, and silicone oil 203 is injected inside the heating chamber 200.

[0025] The above scheme involves heating the silicone oil 203 inside the heating chamber 200 using an electric heating tube 201. As the heat of the silicone oil 203 increases, it is transferred to the storage beaker 101 through the outer wall of the heating chamber 200 and the silicone thermal pad 104, thus increasing the temperature of the water inside the storage beaker 101. The temperature sensor 202 can measure the temperature inside the heating chamber 200 in real time.

[0026] In this embodiment, preferably, a PLC control panel 103 is fixedly installed on one side of the heat preservation box 100, and the PLC control panel 103 is electrically connected to the electric heating tube 201 and the temperature sensor 202.

[0027] The above scheme involves feeding back temperature information to the PLC control panel 103 via the temperature sensor 202, and then controlling the opening and closing of the electric heating tube 201 by setting a temperature threshold inside the PLC control panel 103, thereby achieving temperature control inside the heating chamber 200.

[0028] In this embodiment, preferably, a silicone heat-conducting pad 104 is fixedly disposed between the heating chamber 200 and the storage beaker 101, an annular groove 105 is provided at the top of the heating chamber 200, and an annular protrusion 106 that matches and fits the annular groove 105 is fixedly disposed on the bottom surface of the outer edge of the mouth of the storage beaker 101.

[0029] The above solution fills the gap between the heating chamber 200 and the storage beaker 101 by using the silicone thermal pad 104, making the storage beaker 101 more stable. The flexibility of the silicone thermal pad 104 also provides some protection for the storage beaker 101.

[0030] In this embodiment, preferably, the storage beaker 101 is equipped with a sealing plug 107, the top of the sealing plug 107 is provided with a hidden handle 108, and the sealing plug 107 is made of silicone rubber.

[0031] The above solution achieves the following: the storage beaker 101 is sealed by the sealing plug 107 to prevent liquid leakage, and the hidden handle 108 makes it easy to remove the sealing plug 107 from the storage beaker 101.

[0032] In this embodiment, preferably, the top of the insulated box 100 is hinged to a lid 109 via a hinge 113. A foam padding block 110 is fixedly provided on the side of the lid 109 near the storage beaker 101. The lid 109 is fixed to the top of the insulated box 100 via a flat buckle 112. A U-shaped handle 111 is fixedly provided on the top of the lid 109. The outer shell of the insulated box 100 is made of engineering plastic, aluminum alloy, or stainless steel.

[0033] The above solution allows for the following: the foam clamping block 110 can be used to hold the storage beaker 101 in place, preventing it from shaking and breaking during movement; the U-shaped handle 111 makes it convenient for staff to carry and move the equipment.

[0034] In this embodiment, a high-efficiency thermal insulation storage device for surface water detection is used. First, the surface water to be tested is injected into the storage beaker 101. Then, the beaker is sealed tightly with the sealing plug 107, and the lid 109 is closed and the flat buckle 112 is locked. Then, the electric heating tube 201 is activated through the PLC control panel 103 to heat the silicone oil 203 inside the heating chamber 200. As the heat of the silicone oil 203 increases, it is transferred to the inside of the storage beaker 101 through the outer wall of the heating chamber 200 and the silicone thermal pad 104, so that the water inside the storage beaker 101 is heated. During the heating process, the temperature sensor 202 can measure the temperature inside the heating chamber 200 in real time and feed the temperature information back to the PLC control panel 103. By presetting the temperature threshold inside the PLC control panel 103, the opening and closing of the electric heating tube 201 can be controlled to achieve the temperature control effect inside the heating chamber 200. The storage beaker 101 is made of thin borosilicate glass, which has excellent thermal conductivity, thus greatly reducing the temperature gradient between the heating chamber 200 and the solution inside the storage beaker 101, ensuring that the sample temperature remains within a suitable range. This heating method utilizes silicone oil 203 as a thermally conductive medium wrapped around the outside of the storage beaker 101, which not only improves heating efficiency but also enhances heating uniformity. The low volatility and non-flammability of silicone oil 203 also contribute to the enhanced safety of the equipment.
