Description
Technical Field
[0001] The utility model relates to the field of dam concrete pouring construction, in particular to a device which utilizes reflected sunlight to increase the temperature of a dam concrete bin surface. Background Art
[0002] When constructing concrete dams in cold and high-altitude areas, the temperature plays a vital role in the quality of concrete pouring. Especially when constructing in low temperature seasons or negative temperature seasons, too low temperature affects the hydration reaction of concrete, reduces the strength and impermeability of concrete, reduces the quality of dam concrete, and affects structural safety.
[0003] At present, the construction of concrete dams in cold and high-altitude areas often adopts measures such as heaters and greenhouses to improve the temperature of the dam concrete warehouse surface. This method requires the warehouse surface to be sealed on all sides, which has the problems of high cost, high consumption, concrete unloading, affecting the flat warehouse vibration construction, and complex installation and disassembly. In addition, you can also choose to pour during the daytime period when the temperature is higher. This situation is suitable for small warehouse surfaces but not for large warehouse surfaces. Choosing a period of higher temperature during the day for construction will result in uncertain temperature time periods and too low temperatures on the shady side that is not exposed to sunlight. The large warehouse surface has a large amount of concrete to be poured, which cannot be completed in a short period of time and the concrete pouring needs to be continuous. Therefore, the adverse effects of low temperature periods on the pouring of warehouse surface concrete still exist, especially the temperature of the shady side that cannot be exposed to sunlight is low, and the adverse effects of low temperature on concrete pouring are particularly obvious. Utility Model Content
[0004] The utility model provides a device for increasing the temperature of the dam concrete bin surface, aiming to increase the temperature of the dam concrete bin surface by changing the irradiation direction of sunlight, thereby extending the window period for pouring the dam concrete.
[0005] The technical solution adopted by the utility model is: a device for increasing the temperature of the concrete bin surface of the dam, comprising a base arranged in the illumination area of the dam, a track is arranged on the base, at least one support member that can slide along the track is installed on the track, the support member is installed with a lens, and the emission direction of the lens points to the concrete bin surface of the dam.
[0006] In order to facilitate the construction of the device and ensure that the lens can be in the illumination area for a long time, specifically: the base is arranged at at least one of the two positions of the left bank dam top and the right bank dam top of the dam.
[0007] The base in the device can be a dedicated facility or an existing facility during dam construction, for example, the base is a cable crane platform foundation.
[0008] In order to adjust the positions of the supports and the lenses to adapt to the changes in the solar altitude angle, specifically: the track of the base is located in a horizontal plane and is in an arc shape.
[0009] The lens is used to change the direction of sunlight. Specifically, the lens is a plane mirror, a concave reflector, a convex reflector or a lens.
[0010] In order to allow the lens to receive more sunlight, specifically: the support is divided into two sections and presents an obtuse angle, one side of the obtuse angle is vertical and can be installed on the track rotatably around its axis, and the lens is installed at the end of the other side of the obtuse angle.
[0011] In order to drive the support member to move along the track, thereby adjusting the position of the lens and correspondingly changing the emission direction and range of the lens, further: a driving device for driving the support member to move along the track is arranged between the support member and the track.
[0012] In order to prevent the support member from falling off the track, further: an anti-slip structure is provided between the support member and the track; or a driving device is installed on the track, the support member is installed on the driving device, and an anti-slip structure is provided between the driving device and the track. For example, the anti-slip structure is: the track is provided with a dovetail groove on the top surface of the base, and the support member or the driving device is provided with a tenon adapted to the dovetail groove; or the anti-slip structure is: two mutually parallel slide grooves are provided on the base, the slide groove is L-shaped in a cross section perpendicular to the length direction of the slide groove, a T-shaped solid structure is formed between the two slide grooves, the support member or the driving device is provided with a slot with a T-shaped cross section, and the two sides of the slot are L-shaped solid structures respectively and are stuck in the two slide grooves of the base.
[0013] The beneficial effects of the utility model are as follows: the device utilizes the characteristics of sufficient light and strong ultraviolet rays in high-cold and high-altitude areas to allow sunlight to irradiate the lens, which is then reflected or refracted to the concrete surface of the dam, thereby increasing the temperature and brightness of the concrete surface of the dam. Since the support and the lens can slide along the track as a whole, the position of the lens can be adjusted according to the lighting conditions, thereby increasing the amount of sunlight received by the lens. The device is installed in a high-position illumination area, which does not affect the concrete unloading and pouring construction, and also saves energy. It has low implementation costs and is easy to maintain, and can effectively extend the window period for pouring dam concrete in high-cold and high-altitude areas. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model will be further described below in conjunction with the accompanying drawings.
[0021] like Figure 1 As shown, the device for increasing the temperature of the concrete surface of the dam comprises a base 1 arranged in the illumination area of the dam, a track is arranged on the base 1, at least one support member 2 that can slide along the track is installed on the track, and the support member 2 is installed with a lens 3, and the emission direction of the lens 3 points to the concrete surface of the dam. The number of the support member 2 and the lens 3 as a whole is multiple, and the number of the support member 2 and the lens 3 as a whole is multiple. Figure 1 In the embodiment shown, the number of the support member 2 and the lens 3 as a whole is three. The device utilizes the characteristics of sufficient sunlight and strong ultraviolet rays in high-cold and high-altitude areas, so that the lens 3 reflects or refracts the sunlight to the dam concrete warehouse surface after receiving the sunlight, thereby increasing the temperature of the dam concrete warehouse surface, especially increasing the temperature of the dam concrete warehouse surface that cannot be exposed to sunlight. The sunlight irradiated to the dam concrete warehouse surface through the lens 3 also increases the brightness of the cast dam section 5 and the spandrel groove 6, which is convenient for construction.
[0022] The base 1 plays the role of supporting and fixing the support member 2 and the lens 3. The base 1 can be a dedicated facility, that is, the base 1 is dedicated to supporting and fixing the support member 2 and the lens 3, or it can be an existing facility during the construction of the dam, that is, other facilities during the construction of the dam are used as the base 1. For example, the base 1 is the foundation of the cable platform, and the foundation of the cable platform is generally a reinforced concrete structure. In order to ensure that the lens 3 can be in the illumination area for a long time, the base 1 is arranged at a relatively high position, such as the dam top on the left bank and the dam top on the right bank of the dam, or a position close to the dam top. A track is arranged on the base 1, and the track can be a solid structure fixed to the base, or it can be a slide groove arranged on the base 1. The support member 2 is slidably mounted on the track, so that the support member 2 and the lens 3 can slide along the track as a whole, so that the lens 3 can be adjusted according to the lighting conditions, especially the position of the lens 3 can be adjusted according to the solar altitude angle. The track guides the movement of the support member 2 and the lens 3. In order to better adapt the support member 2 and the lens 3 to the changes in the solar altitude angle, the track of the base 1 is located in a horizontal plane and is in an arc shape, such as Figure 3 shown.
[0023] The support member 2 plays the role of supporting and fixing the lens 3. The lens 3 is an optical device used to receive sunlight, change the direction of sunlight, and make the sunlight irradiate the concrete surface of the dam. The lens 3 can change the direction of sunlight by reflection or refraction. The lens 3 is a plane reflector, a concave reflector, a convex reflector or a lens. The lens 3 generally changes the direction of sunlight by reflection, so the lens 3 is generally a reflector.
[0024] In order to drive the support member 2 to move along the track, thereby adjusting the position of the lens 3 and correspondingly changing the emission direction and range of the lens 3, a driving device 4 is provided between the support member 2 and the track for driving the support member 2 to move along the track. The driving device 4 generally includes a motor. The driving device 4 is connected to a remote control device, and can also realize remote control or even automatic control. The driving device 4 can drive itself, the support member 2 and the fixed lens 3 to slide along the track as a whole. For example, see Figure 1 and Figure 2 The driving device 4 is slidably mounted on the track, the support member 2 is divided into two sections and is in an obtuse angle shape, one side of the obtuse angle is vertical, the vertical side is mounted on the driving device 4 and can rotate around its axis, and the end of the other side of the obtuse angle is fixedly mounted on the lens 3. The two sections of the support member 2 can be fixedly connected, and a more preferred solution is to set an adjustment structure between the two sections to adjust the angle.
[0025] In order to prevent the support member 2 from falling off the track, when the support member 2 is directly installed on the track, an anti-falling structure is set between the support member 2 and the track; when the drive device 4 is installed on the track, the support member 2 is installed on the drive device 4, and an anti-falling structure is set between the drive device 4 and the track. The following is an example of the release structure, the anti-falling structure is: the track is provided with a dovetail groove on the top surface of the base 1, and the support member 2 or the drive device 4 is provided with a tenon adapted to the dovetail groove, and the tenon is located in the dovetail groove to achieve an anti-falling effect. For another example, see Figures 1 to 3 The anti-slip structure is as follows: two parallel slide grooves are arranged on the base 1, and the slide groove is L-shaped in the cross section perpendicular to the length direction of the slide groove, and a T-shaped entity structure is formed between the two slide grooves. The support member 2 or the driving device 4 is provided with a slot with a T-shaped cross section, and the two sides of the slot are L-shaped entity structures and are clamped in the two slide grooves of the base 1.
