Description

Technical Field

[0001] This utility model relates to the field of valve insulation boxes, and in particular to an automatic constant temperature and antifreeze insulation box. Background Technology

[0002] In municipal water supply and fire protection, a large number of valves and pipelines are exposed to outdoor or unheated environments. In cold seasons, when the ambient temperature drops below freezing, the liquid medium remaining in the valve cavity or pipeline will freeze. Freezing can not only cause valves to fail to open and close properly and pipelines to become blocked, affecting system operation, but may also cause valve bodies or pipe fittings to crack due to the expansion of ice volume, resulting in medium leakage, equipment shutdown and even safety accidents, bringing huge economic losses and maintenance burdens.

[0003] Traditional antifreeze measures mainly rely on electric heating tape wrapped with insulation cotton, or adding an insulated box around the valve. However, existing insulated boxes are extremely inconvenient to install and disassemble, and their insulation and sealing performance is insufficient. Heat easily escapes from the box seams, doors, observation windows, and pipe penetrations, resulting in low heat utilization and difficulty in guaranteeing antifreeze effectiveness. Uneven heat distribution within the box is also a common problem, easily causing overheating near the heater while the far end remains frozen. Furthermore, frequent opening of the box for inspection leads to significant heat loss. Therefore, there is an urgent need to develop an automatic constant-temperature antifreeze insulated box that allows for quick installation and disassembly, reliable insulation performance, uniform internal temperature, and significantly reduced maintenance work. Utility Model Content

[0004] In order to overcome the shortcomings of existing insulated boxes, such as inconvenient disassembly and assembly, insufficient insulation and sealing performance, easy heat loss from the box seams, doors, observation windows and pipe penetrations, resulting in low heat utilization and uneven heat distribution inside the box, this utility model aims to provide an automatic constant temperature and freeze protection insulated box that can be quickly disassembled and assembled, has reliable insulation performance, uniform internal temperature, and significantly reduces maintenance work.

[0005] This utility model is achieved by the following specific technical means: An automatic constant temperature and freeze-proof insulated box includes a box body, which is a split structure composed of a first half box body and a second half box body that can be detachably assembled via quick-connect locking. Both the first and second half box bodies include an inner shell, an outer shell, and insulating filler between the inner and outer shells. An inspection port is provided on the side of the second half box body away from the first half box body, and a door is provided at the inspection port. One end of the door is hinged to the box body, and the other end is fastened to the door via a rotary lock. An observation window is provided on the door, and a transparent glass is fixedly installed in the observation window. An electric heating device, a temperature sensor, and a temperature controller electrically connected to the electric heating device and the temperature sensor are provided inside the box body. A clearance hole for avoiding valves and pipelines is provided on the box body, located at the junction of the first and second half box bodies. The first half of the enclosure is divided into two semi-holes. A sealing structure is provided at the clearance hole to enhance sealing. The sealing structure includes a sealing sleeve formed by splicing two semi-circular sleeves and fixing them to the edges of the two semi-holes respectively. The inner wall of the sealing sleeve forms a sealing contact surface extending axially along the valve pipe, and a sealing ring is embedded in the sealing contact surface through an annular groove. An air circulation fan is also provided inside the enclosure to agitate the internal air and distribute heat evenly. A lighting lamp is also provided inside the enclosure. An electrical connection is provided on the enclosure or door to control the lighting lamp's switch. On the mating end faces of the first and second half of the enclosure, an interlocking sealing structure is provided, consisting of a groove surrounding the edge and a matching protrusion, and a sealing gasket is provided on the mating surface of the groove and the protrusion.

[0006] Furthermore, the transparent glass is a double-layered vacuum glass panel; this increases the heat insulation effect and prevents heat loss from the transparent glass.

[0007] Furthermore, a sealing rubber gasket is provided on the contact surface between the door and the body of the cabinet; this increases the sealing effect and prevents heat from leaking out from the connection between the door and the body.

[0008] Furthermore, at least two independent sealing rings are embedded in the sealing contact surface through an annular groove; this improves the sealing effect and reduces heat loss.

[0009] Furthermore, the electric heating device is a PTC ceramic heater.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention achieves the effects of quick assembly and disassembly, reliable thermal insulation performance, uniform internal temperature, and significantly reduced maintenance work.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings: Example

[0017] An automatic temperature-controlled, freeze-proof insulated box, such as Figure 1-4As shown, the enclosure includes a housing, which is a split structure composed of a first half-body 1 and a second half-body 2, which can be detachably assembled via quick-connect latches 3. Both the first half-body 1 and the second half-body 2 include an inner shell, an outer shell, and insulating filler between the inner and outer shells. An inspection port is located on the side of the second half-body 2 away from the first half-body 1, and a door 4 is provided at the inspection port. One end of the door 4 is hinged to the housing via a hinge 5, and the other end is fastened to the door 4 via a rotary latch 6. An observation window is provided on the door 4, and a transparent glass 7 is fixedly installed in the observation window. An electric heating device 8, a temperature sensor 9, and a thermostat 10 electrically connected to the electric heating device 8 and the temperature sensor 9 are installed inside the housing. A clearance hole 101 for avoiding valves and pipes is provided on the housing, located at the junction of the first half-body 1 and the second half-body 2, and divided into two halves. The clearance hole 101 is provided with a sealing structure to enhance the sealing performance. The sealing structure includes a sealing sleeve 102, which is formed by splicing two semi-circular sleeves and is fixed to the edges of the two semi-holes respectively. The inner wall of the sealing sleeve 102 forms a sealing contact surface that extends axially along the valve pipe, and a sealing ring 103 is embedded in the sealing contact surface through an annular groove. An air circulation fan 11 is also provided inside the box to agitate the internal air and distribute heat evenly. A lighting lamp 12 is also provided inside the box to provide illumination. A switch 13 is provided on the box or the box door 4 that is electrically connected to the lighting lamp 12 and is used to control the lighting lamp 12. On the joint end face of the first half box 1 and the second half box 2, a fitting sealing structure is provided, which is composed of a groove 104 surrounding the edge and a matching protrusion 105. A sealing gasket 106 is provided on the mating surface of the groove 104 and the protrusion 105.

[0018] Working principle: During installation, utilizing the split design of the enclosure, the first half of the enclosure 1 and the second half of the enclosure 2 are joined together from both sides of the valve pipe and secured with quick-connect locks 3. Subsequently, the power is turned on, and the temperature control system starts working. The temperature sensor 9 monitors the temperature inside the enclosure in real time and transmits the signal to the temperature controller 10. When the monitored temperature is lower than the preset anti-freeze lower limit of the temperature controller 10, the temperature controller 10 automatically starts the electric heating device 8 to heat the enclosure. When the temperature reaches the preset upper limit, the heating stops. This cycle is repeated to keep the temperature inside the enclosure within the set range, effectively preventing the pipes and valves from freezing due to low temperatures. To ensure insulation effect and uniformity, the insulation filler in the enclosure layer can greatly reduce the loss of internal heat to the outside. At the same time, after the air circulation fan inside the enclosure is turned on, it can disturb the internal air, force the hot air to circulate, eliminate local cold spots, and make the heat distribution inside the enclosure more uniform, avoiding the problem of overheating in the area near the heating device while the area far away may still freeze. The status of the equipment inside the box can be directly viewed through the observation window, eliminating the need to frequently open the box door 4. When maintenance is required, the box door 4 can be opened directly for operation, or the entire box can be quickly disassembled into two halves by releasing the quick-connect lock 3, which greatly facilitates the installation, maintenance and repair of large valves.

[0019] In terms of insulation and sealing, the split design of the enclosure is connected by quick-connect locks 3, and the joint end face adopts an interlocking sealing structure, which effectively prevents heat loss through the joint. The enclosure door 4 enhances the airtightness with sealing rubber gaskets, and the observation window on it adopts a double-layer vacuum glass plate, which facilitates observation of the internal situation while greatly reducing heat conduction and heat loss through this point. For valves and pipes passing through the enclosure, the sealing sleeve 102 at the avoidance hole 101 and at least two independent sealing rings 103 set on its inner wall constitute a multi-level seal, tightly wrapping the pipe and effectively blocking the heat dissipation channel of this critical part.

[0020] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0021] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
