Description

Technical Field

[0001] The present invention relates to the field of construction equipment, and more specifically, to a photovoltaic self-powered thermal insulation device for concrete column grouting sleeves in winter construction. Background Art

[0002] According to the relevant regulations of prefabricated buildings, during winter grouting construction, the temperature of the environment around the grout should be controlled above 5°C. When necessary, heat preservation and heating measures need to be taken at the joints to ensure that the temperature does not drop below 10°C during the 48-hour setting and hardening process of the grout. When entering winter construction, the temperature drops below 5°C, and most areas in the north will remain below 0°C for a long time. If effective heating and heat preservation measures are not taken, grouting construction cannot be carried out, which will cause the grouting operation to stop during winter construction, and the advantages of prefabricated buildings in shortening the construction period cannot be demonstrated.

[0003] Currently, the prior art mostly uses heat preservation blankets or electric tracing tapes for heating. However, using cotton quilts or heat preservation blankets for heat preservation has the following defects: on the one hand, the installation is relatively inconvenient, the temperature at the joints cannot be clearly displayed, the temperature at the joints cannot be ensured to be within a suitable range, and the heat preservation effect is not ideal. On the other hand, in on-site construction, the columns are spaced apart and far from each other. If electric blankets or electric tracing tapes are used, long wires are required to supply power to the device. For relatively large projects, there may be many precast columns to be connected on-site. Without using independent power supply, if a large number of heating devices are connected to the ordinary circuit at the same time, it will affect the working power of the device, and the ideal heating effect cannot be achieved either. The joints of the precast columns cannot be effectively heat-insulated, affecting the final construction quality.

[0004] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Invention

[0013] Further, in order to effectively avoid the influence on the photoelectric conversion caused by a large amount of pollutants accumulating on the surface of the photovoltaic panel, the cleaning mechanism includes a brush installed on one side of the photovoltaic panel.

[0032] To further illustrate each embodiment, the present invention provides attached drawings. These attached drawings are part of the disclosure of the present invention. They are mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0033] According to an embodiment of the present invention, a photovoltaic self-powered thermal insulation device for concrete column grouting sleeves in winter construction is provided.

[0034] Now, the present invention will be further described in combination with the attached drawings and specific implementation manners. As Figures 1 - 10As shown in the figure, the photovoltaic self-powered concrete column grouting sleeve thermal insulation device according to the embodiment of the present invention includes a first thermal insulation board 1. One end of the first thermal insulation board 1 is provided with three groups of second thermal insulation boards 2 connected in sequence. And between the first thermal insulation board 1 and the second thermal insulation boards 2 and between adjacent second thermal insulation boards 2 are connected by a number of hinges 3. In specific application, the hinges 3 are used to connect adjacent two thermal insulation boards together, reducing the pulling on the heating belt 4. And each pair of thermal insulation boards is connected by two hinges. No hinge or hinge is provided at the head and tail docking place. The device can be connected together by the connecting rod 8. The first thermal insulation board 1 and the head and tail of the three groups of second thermal insulation boards 2 are connected by the connecting rod 8 to form a rectangular structure. In specific application, each thermal insulation device is configured with four connecting rods 8. And the connecting rod 8 only has the functions of thermal insulation and connection, without the function of heating; between the middle parts of the inner sides of the first thermal insulation board 1 and the second thermal insulation boards 2, there is a heating belt 4. In specific application, the heating belt 4 in this embodiment is formed by a single electric heating tape arranged in a spiral. The heating belt 4 is continuous on the four board members (i.e., the first thermal insulation board and the three groups of second thermal insulation boards) without interruption. Without interruption, it can make the heating belt 4 have a certain effect of connecting the board members, and at the same time can supply heat evenly, and the temperatures of each part on the heating belt 4 are approximately the same. Between the top and bottom of the inner sides of the first thermal insulation board 1 and the second thermal insulation boards 2, there are first thermal insulation rubber pads 5. In specific application, the heating belt 4 and the first thermal insulation rubber pads 5 in this embodiment are continuous on the four thermal insulation boards. And the first thermal insulation rubber pads 5 are arranged in two rows, having a certain thickness. At the same time, when the thermal insulation device is installed on the column, there is a certain extrusion force between the thermal insulation device and the column, which can squeeze the first thermal insulation rubber pads 5, so that the first thermal insulation rubber pads 5 can be more tightly attached to the column, having a certain sealing effect. The first thermal insulation rubber pads 5 can also generate a certain frictional force during the extrusion process to prevent the thermal insulation device from sliding down, so that the thermal insulation device can be fixed in one position. On the outer side of the second thermal insulation board 2, there is a photovoltaic panel 6. On one side of the surface of the photovoltaic panel 6, there is a cleaning mechanism 7. In specific application, the photovoltaic panel 6 is embedded in the back of the second thermal insulation board 2. The electric energy generated by the photovoltaic panel 6 is used to charge the energy storage battery through the wiring installed inside the photovoltaic panel member.

[0035] In one embodiment, connection blocks 9 are provided on both sides of the connecting rod 8, and connection grooves 10 matching the connection blocks 9 are formed at both ends of the first heat preservation board 1 and the second heat preservation board 2. The inside of the connecting rod 8 is filled with heat preservation materials 11. In specific applications, since the space inside the connecting rod 8 is relatively small and it is not convenient to place a heat preservation blanket, in this embodiment, heat preservation materials such as heat preservation cotton are packed into a strip-shaped cloth bag and then placed at the position of the cavity of the connecting rod 8. Heat preservation rubber pads II 12 are provided at the top corners and bottom corners of the connecting rod 8. In specific applications, after the heat preservation device is installed at the connection of the precast column, the connecting rod 8 is installed. The relative positions of the rubber heat preservation pads on the connecting rod 8 and the rubber heat preservation pads on the heat preservation device are the same and complement each other, just forming an annular structure, so that a relatively sealed cavity is formed inside the heat preservation device. At the same time, the easy-to-deform characteristic of the rubber heat preservation pad makes the installation of the connecting rod 8 more convenient. At the same time, after installation, the internal space can be relatively sealed. Setting two layers of rubber heat preservation pads can enhance the sealing and heat preservation effects, so as to achieve a better heat preservation effect while facilitating the connection between the first heat preservation board 1 and the second heat preservation board 2.

[0036] In one embodiment, a power socket 13 is provided at one outer end of the first heat preservation board 1. A power quantity indicator light 14 is provided at the bottom of the power socket 13. In specific applications, when the storage battery 107 is fully charged, all five power quantity indicator lights 14 are fully lit, so that this heat preservation device can be used for work. A temperature display screen 15 is provided at the bottom of the power quantity indicator light 14. A switch button 16 is provided at the bottom of the temperature display screen 15. A controller 17 is provided at the bottom of the switch button 16. The first heat preservation board 1 includes a first housing 101. In specific applications, the housings in this embodiment are all made of plastic. A matching first heat preservation housing 102 is clamped on one side of the first housing 101. A first heat preservation blanket 103 is filled between the first heat preservation housing 102 and the first housing 101. Air circulation grooves 104 are formed at the top and bottom on one side of the first heat preservation housing 102, which are used to protect the internal heat preservation cotton, form a certain air circulation channel, and are also used to fix the fans. Fans 105 are provided inside the air circulation grooves 104. In specific applications, when the switch of the heat preservation device is pressed, it starts to work together with the heat preservation device, which can make the heat circulate faster, and can transfer the heat in the heating belt 4 to other heat preservation areas through the circulating air medium, reducing the use of the heating belt 4 to a certain extent. An installation groove 106 matching the heating belt 4 is formed in the middle of one side of the first heat preservation housing 102. A storage battery 107 is provided inside the first heat preservation blanket 103, and the storage battery 107 is electrically connected to the fan 105, the heating belt 4, the photovoltaic panel 6, the power socket 13, the power quantity indicator light 14, the switch button 16 and the controller 17 respectively, so as to facilitate the realization of the heat preservation and control effects. In specific applications, when the heat preservation device is not working, the storage battery 107 can be placed in the sun with the whole device unfolded, and the photovoltaic panel 6 converts light energy into electrical energy and stores it in the storage battery 107. When the heat preservation device works, the heat preservation device is installed at the position where heat preservation is required at the connection of the precast column. After pressing the start switch, the heat preservation device starts to work, and the storage battery 107 supplies power to the heating belt 4, the fan 105, etc.

[0037] In specific applications, the power socket 13 can supply power to the storage battery 107 through an external power source. During the operation of the heat preservation device, the power supply of the photovoltaic panel 6 to the storage battery 107 often cannot ensure the continuous use of the heat preservation device. Especially at night when there is no sunlight and the photovoltaic panel 6 cannot convert light energy into electrical energy, an external power source needs to be connected for supplementary power to ensure the normal use of the device.

[0038] During the use of the heat preservation device, the storage battery 107 does not always have power. It is necessary to judge whether the storage battery 107 is short of power or whether the heat preservation device is operating normally. When the power in the storage battery 107 is sufficient, all the power quantity indicator lights 14 are lit, and they gradually decrease as the power decreases.

[0039] The temperature display screen 15 is part of the controller and shows the average temperature of the four pt100 temperature sensors 18. The controller 17 processes the temperatures transmitted by the temperature sensors 18, controls the power of the heating belt 4, adjusts and controls the temperature of the insulation area, and can design the temperature range for insulation according to needs, that is, the lower limit and upper limit of the insulation temperature; the controller 17 processes the data of the temperature sensors 18, and then adjusts the power of the heating belt 4 to control the temperature of the insulation area, keeping the temperature within a reasonable range, thereby saving the use of electricity to a certain extent and prolonging the service life of the insulation device; there is a display panel for the average temperature of the measuring points outside the controller 17, with two intervals for insulation and heating. When the temperature is lower than the lower limit of the designed temperature, the power of the heating belt is increased to raise the temperature of the insulation area. When the temperature rises to the upper limit of the insulation design temperature, the controller 17 controls the heating belt 4 to work at a lower power and enters the insulation state;

[0040] In one embodiment, the second insulation board 2 includes a second housing 201. A mating second insulation housing 202 is clamped on one side of the second housing 201, and a second insulation blanket 203 is filled between the second insulation housing 202 and the second housing 201; air circulation grooves 204 are formed at the top and bottom on one side of the second insulation housing 202. In specific applications, the air circulation grooves 204 can isolate the air circulation area and the insulation blanket area, and at the same time form a rectangular space structure for the air to flow through. An installation groove 205 for mating with the heating belt 4 is formed in the middle of one side of the second insulation housing 202. Temperature sensors 18 are arranged inside both the first air circulation groove 104 and the second air circulation groove 204. Wires 19 are arranged between the inner corners of the first insulation blanket 103 and the second insulation blanket 203, and the wires 19 are respectively connected to the fan 105, the storage battery 107, the heating belt 4, the photovoltaic panel 6, the power socket 13, the power indicator light 14, the temperature display screen 15, the switch button 16, the controller 17 and the temperature sensors 18, so as to achieve a better insulation effect; in specific applications, the temperature sensors 18 (model pt100) are in parallel wiring, and the whole of the temperature sensors 18 is in series with the controller 17. The photovoltaic panels 6 are in parallel wiring. In addition, in order to avoid the influence of the expansion or assembly of the insulation boards on the wires 19, wire protection sleeves are provided at the joints between the insulation boards.

[0041] In one embodiment, the cleaning mechanism 7 includes a brush 701 installed on one side of the photovoltaic panel 6. A moving rod 702 is provided on the side of the brush 701 away from the photovoltaic panel 6, and a fixed block 703 is provided in the middle of the side of the moving rod 702 away from the brush 701. Sliders 704 are provided at both ends of the moving rod 702, and guide rods 705 are inserted through the middle of the sliders 704. Installation grooves three 706 that match the guide rods 705 and the sliders 704 are provided on one side of the top and one side of the bottom of the housing two 201. By providing the cleaning mechanism 7, it enables the staff to drive the brush 701 to clean the surface of the photovoltaic panel 6 by simply manually waving the fixed block 703, thereby effectively avoiding the impact on its photoelectric conversion caused by a large amount of pollutants accumulating on the surface of the photovoltaic panel 6.

[0042] In specific applications, the cleaning mechanism 7 in this embodiment can also be driven electrically, that is, replacing the current guide rods 705 and sliders 704 with threaded rods and corresponding threaded sliders, and a driving motor matching the threaded rod is provided at one end of the housing two 201. And the two groups of driving motors are synchronously driven by the controller 17 (the rotation speed and direction are exactly the same), and the forward and reverse rotation of the driving motor is controlled by the controller 17 (that is, controlled by a program pre-written in the controller), so that the brush 701 can be driven by the driving motor to clean the surface of the photovoltaic panel 6.

[0043] To facilitate the understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0044] In actual application, first, the heat preservation device is correctly installed in the heat preservation area of the concrete column grouting sleeve (that is, the first heat preservation board 1 and three groups of the second heat preservation boards 2 are arranged around the outside of the concrete column grouting sleeve and fixed by the connecting rods 8. When the four plate members are correctly attached to the column, the three photovoltaic panels 6 are successively oriented towards the sunny places, and the first heat preservation board 1 is oriented towards the interior of the building, so as to maximize the utilization of the photovoltaic panels 6 and extend the service time of the heat preservation device). Subsequently, the external switch button 16 is turned on, and the heating belt 4 starts to work, causing the temperature in the heat preservation area to rise. After the temperature in the heat preservation area rises to the designed specified upper temperature limit, the power of the heating belt 4 is reduced through the controller 17. When the temperature in the heat preservation area rises to the designed specified lower temperature limit, the power of the heating belt 4 is increased through the controller 17, so that the heat preservation area is always within a suitable temperature range. In addition, during the day under sunlight, the three photovoltaic panels 6 can also generate electricity to charge the storage battery 107, and the storage battery 107 discharges to make the heating belt 4, the fan 105, etc. work. At night, the power of the storage battery 107 independently supplies power to the heating belt 4, the fan 105, etc. After the heat preservation time reaches 48 hours, the external power supply is turned off, the device stops working, and the connecting rods 8 at the four corners are pulled out in sequence to recycle the device, or the device can continue to be placed in the sunlight to convert light energy into electrical energy to supply power to the energy storage battery.

[0045] To sum up, by means of the above technical solutions of the present invention, through the provision of the first heat preservation board 1, the second heat preservation board 2, the heating belt 4, the first heat preservation rubber pad 5, the photovoltaic panel 6 and the connecting rod 8, not only can the first heat preservation board 1 and the second heat preservation board 2 be quickly installed in the heat preservation area of the concrete column grouting sleeve under the action of the connecting rod 8, facilitating the rapid installation of the heat preservation device, but also the photovoltaic panel 6 can collect solar energy in real time and convert it into electrical energy for storage, so as to assist the power grid in supplying power to electrical components, enabling the first heat preservation board 1, the second heat preservation board 2, the heating belt 4 and the first heat preservation rubber pad 5 to continuously perform heat preservation treatment on the heat preservation area of the concrete column grouting sleeve, better meeting the heat preservation requirements of the heat preservation area of the concrete column grouting sleeve. In addition, by providing the temperature display screen 15, the controller 17 and the temperature sensor 18, the present invention can not only clearly display the temperature data of the heat preservation area of the concrete column grouting sleeve under the action of the temperature display screen 15 and the temperature sensor 18, but also accurately regulate the temperature of the heat preservation area under the action of the controller 17 and the heating belt 4, so that the temperature of the heat preservation area can always be pre - in an ideal temperature range, achieving a better heat preservation effect. In addition, by providing the cleaning mechanism 7, the staff only needs to manually move the fixed block 703 to drive the brush 701 to clean the surface of the photovoltaic panel 6, effectively avoiding the influence on its photoelectric conversion caused by a large amount of pollutants accumulating on the surface of the photovoltaic panel 6.
