Description

水平百叶排烟窗Horizontal shutter smoke exhaust 技术领域Technical field
本发明涉及通风设备领域,具体是指一种水平百叶排烟窗。The invention relates to the field of ventilation equipment, in particular to a horizontal louver smoke exhaust window.
背景技术Background technique
百叶窗是窗子的一种式样,起源于中国。百叶窗既可以作为一种装饰,同时也可以起到通风透光的作用,在现代建筑中常常会用到。传统的百叶窗均为垂直设计,其在一些大型厂房、车间或仓库并不适用。为了解决上述问题,申请号为201110213427.6的中国发明专利公开了一种并列风道式自然通风器,其具体由骨架、至少两组防雨板、设置在最下方一组防雨板的下端边沿下方的排水槽等组成;然而,经过长时间的试验,该专利所公开的并列风道式自然通风器主要存在以下问题;该并列风道式自然通风器仅仅是在最下方一组防雨板的下端边沿下方设置排水槽,并且为了减少其阻挡气流的作用,水槽不能做宽了,在这种结构下如果遇到暴雨,大量的雨水则会汇集到排水槽里,雨水容易从水槽里溢出而落入到室内;如果为了满足排水要求而将排水槽加宽,加宽的排水槽则会明显的阻挡气流,使得通风器的有效通风面积急剧变小,无法满足通风要求;如果将排水槽的深度加的很深,则不但会影响通风器的美观,而且还会导致通风器骨架的承力性能降低,为了提高承力性能,则需要大大提高骨架的厚度,这样不仅会增加材料成本,而且会在安装上带来难以处理的其它工程问题。除上述问题以外,该并列风道式自然通风器还存在一些其它问题,诸如:Blinds are a style of windows that originated in China. Blinds can be used as a decoration, but also play a role in ventilation and light transmission, often used in modern buildings. Traditional blinds are designed vertically, which is not suitable for some large factories, workshops or warehouses. In order to solve the above problems, the Chinese invention patent with application number 201110213427.6 discloses a parallel air duct type natural ventilator, which is specifically composed of a skeleton, at least two sets of rainproof plates, and a lower edge of the lowermost set of rainproof plates. However, after a long period of testing, the parallel air duct natural ventilator disclosed in this patent mainly has the following problems; the parallel air duct natural ventilator is only at the bottom Drainage troughs are provided under the lower edge, and in order to reduce the effect of blocking the airflow, the water troughs cannot be widened. In this structure, if heavy rain is encountered, a large amount of rainwater will be collected into the drainage troughs, and rainwater will easily overflow from the water trough. Fall into the room; if the drainage groove is widened in order to meet the drainage requirements, the widened drainage groove will obviously block the airflow, so that the effective ventilation area of the ventilator becomes sharply smaller and cannot meet the ventilation requirements; if the drainage groove is If the depth is deep, it will not only affect the appearance of the ventilator, but also reduce the bearing performance of the ventilator frame. In order to improve the bearing performance, it is necessary to greatly increase the thickness of the frame, which will not only increase the material cost, but also It will bring other engineering problems that are difficult to deal with during installation. In addition to the above problems, there are some other problems with this parallel duct natural ventilator, such as:
(1)通风器的有效通风面积,是指气流通过通风器时所经过的最小面积;有效通风面积比率,是指通风器的有效通风面积占通风器面积(或屋面开口面积)的比值。申请号为201110213427.6的专利虽然在说明书中提出来“其有效通风面积大于屋面开口面积的80%”,但并没有公开大于80%的其它相关信息。根据公开的说明书附图信息,其相邻两块防雨板之间的通风风道中空气能够流通的水平距离很大,是大于80%的,上面两层的风道其水平距离若忽略防雨板自身厚度的影响,则为100%,最下面一层防雨板按照水平距离来计算,能够直 接阻挡气流的只有水槽底面的宽度的位置,若以通风风道能进行空气流通的水平距离作为其有效通风宽度,则该专利的有效通风面积能大于80%;然而实际计算通风风道的有效通风面积时,是以该风道的长度乘以该风道之间的最狭窄的宽度,即能够通风的最小距离(即垂直距离);在该专利中,其排水槽是设置在最下方一组防雨板的下端边沿的下方,其排水槽的设置位置会阻挡气流,减少该通风风道的有效通风面积,使得通风风道之间用于通风的垂直距离变小,进而减小了整个通风器的有效通风面积。根据有效通风面积的计算方法,该专利公开的附图1、附图5,其有效通风面积比率为在39%~41%之间;附图3,其有效通风面积比率在34%~37%之间。该专利公开的信息中,没有载明能达到80%的有效通风面积比率,同时又能达到良好防水作用的技术方案。而实际使用中,市场上能获得青睐的是有效通风面积比率较大的技术方案。该专利公开的信息中,其有效通风面积与市场上常见的有效通风面积比率在30%~40%的通风器没有明显的通风优势。(1) The effective ventilation area of the ventilator refers to the smallest area through which the airflow passes; the effective ventilation area ratio refers to the ratio of the effective ventilation area of the ventilator to the area of the ventilator (or roof opening area). Although the patent with the application number 201110213427.6 proposes in the specification that "the effective ventilation area is greater than 80% of the roof opening area", it does not disclose other relevant information greater than 80%. According to the information in the drawings of the published specification, the horizontal distance that the air can circulate in the ventilation air duct between the two adjacent rain plates is very large, which is greater than 80%. If the horizontal distance of the upper two air ducts is negligible for rain The effect of the thickness of the board itself is 100%. The bottom layer of the rainproof board is calculated according to the horizontal distance. Only the width of the bottom surface of the sink can directly block the airflow. If the horizontal distance of the ventilation air channel can be used as the horizontal distance For the effective ventilation width, the effective ventilation area of the patent can be greater than 80%; however, when actually calculating the effective ventilation area of the ventilation air duct, the length of the air duct is multiplied by the narrowest width between the air ducts, that is The minimum distance that can be ventilated (ie, the vertical distance); in this patent, the drainage slot is located below the lower edge of the bottom set of rainboards, and the placement of the drainage slot will block the airflow and reduce the ventilation duct The effective ventilation area makes the vertical distance between the ventilation ducts for ventilation smaller, which in turn reduces the effective ventilation area of the entire ventilator. According to the calculation method of the effective ventilation area, the figures 1 and 5 of the patent disclosure have an effective ventilation area ratio of 39% to 41%; and figure 3 has an effective ventilation area ratio of 34% to 37% between. The information disclosed in this patent does not specify a technical solution that can achieve an effective ventilation area ratio of 80% and at the same time achieve a good waterproof effect. In actual use, the technical solution with a large effective ventilation area ratio is favored in the market. According to the information disclosed in this patent, a ventilator whose effective ventilation area is 30% to 40% of the effective ventilation area on the market has no obvious advantage in ventilation.
(2)该并列风道式自然通风器在使用时,如果雨水直接打在二层防雨板的正面时,雨水会溅在第二层防雨板的背面形成水滴,该水滴吸附在第二层防雨板的背面,并沿着防雨板倾斜方向下落时会在任意位置(与降雨量,风速,风力大小等因素有关)直接落下来,由于第三层防雨板与第三层相邻的水槽没有交接,该水滴会通过第三层防雨板及其相邻的水槽之间的空隙直接滴落到室内,使得其防雨性能达不到要求。(2) When the parallel air duct type natural ventilator is used, if rainwater directly hits the front of the second layer rainproof plate, rainwater will splash on the backside of the second layer rainproof plate to form water droplets, and the water droplets are adsorbed on the second The back of the rainproof board and falling along the inclined direction of the rainproof board will fall directly at any position (related to rainfall, wind speed, wind force and other factors), because the third rainproof board is in contact with the third layer. The adjacent water tanks are not connected, and the water droplets will directly drop into the room through the gap between the third layer rainproof plate and the adjacent water tank, so that its rainproof performance does not meet the requirements.
(3)当雨水直接打在第二层防雨板上时,产生的溅雨在风力的作用下,会通过第三层防雨板及相邻的水槽之间的空隙直接进入室内,使得其防雨性能达不到要求。(3) When rainwater hits directly on the second rainproof plate, the generated splashing rain will directly enter the room through the gap between the third rainproof plate and the adjacent water tank under the action of wind force, making it The rainproof performance does not meet the requirements.
(4)第二层防雨板正面上的水,在沿倾斜方向向下流,滴在第三层防雨板正面会产生细小的溅雨溅落在室内,使得其防雨性能达不到要求。(4) The water on the front surface of the second layer rainproof plate flows downward in an oblique direction, and dripping on the front surface of the third layer rainproof plate will cause a small splash of rain to fall indoors, making its rainproof performance not up to the requirements.
(5)在使用时,骨架上会产生水滴,水滴则会沿骨架向下滴入到室内,使得其防雨性能达不到要求。(5) When in use, water droplets will be generated on the skeleton, and the water droplets will drip down into the room along the skeleton, so that its rainproof performance does not meet the requirements.
(6)整个并列风道式自然通风器的重量都是由骨架支撑,骨架都是安装在 基座上,这就需要增加基座的数量,不仅会增加材料成本,而且会提高通风器安装的难度。(6) The weight of the entire parallel air duct type natural ventilator is supported by the skeleton, and the skeleton is installed on the base. This requires increasing the number of bases, which will not only increase the material cost, but also increase the installation of the ventilator. Difficulty.
由于该并列风道式自然通风器存在上述问题,使得该通风器无法得到推广。Due to the above-mentioned problems with the parallel air duct type natural ventilator, the ventilator cannot be promoted.
另外,申请号为201520394299.3的实用新型专利公开了一种水平防雨通风百叶窗,作为通风百叶窗,通风性防雨性能是关键功能,该专利同样没有公示有效通风面积的信息,该专利的防雨性能同样存在重大缺陷,在大风、大雨、暴雨时,风向是随机的,百叶窗的安装方式必须满足使用条件,是不能选择的,这样雨水随风向进入百叶窗内部,直接打在百叶片凹部的中下部时,必定发生溅雨,溅雨会直接进入房间内部,也会溅在相邻百叶片的正面,并汇集流入房间内,因此该专利的缺陷是显而易见的。In addition, the utility model patent with the application number 201520394299.3 discloses a horizontal rainproof and ventilated blind. As a ventilated blind, the ventilation and rainproof performance is a key function. The patent also does not disclose information on the effective ventilation area. The patent's rainproof performance There are also major defects. In strong winds, heavy rains, and heavy rains, the wind direction is random, and the installation method of the blinds must meet the conditions of use. It cannot be selected, so that the rainwater enters the blinds with the wind direction, and directly hits the middle and lower parts of the blinds. At this time, splashing rain must occur, and the splashing rain will directly enter the interior of the room, and will also splash on the front of the adjacent louver, and pool into the room, so the shortcomings of this patent are obvious.
基于此,如何解决上述问题则是目前的当务之急。Based on this, how to solve the above-mentioned problems is currently the top priority.

In this embodiment, each rainproof mechanism includes three louvers 2, and the three louvers 2 are arranged in order from top to bottom. Radiation at any angle from any point on the horizontal plane where the upper end of the uppermost louver 2 is located, the rays are incident on the louver 2 or the drainage groove 3 of any rainproof mechanism, so the rain cannot be Enter the room directly through the louver 2.
相邻两个防雨机构上的百叶片2和排水槽3的形状均相同,且相邻两个防雨机构中同一层的百叶片2之间相互平行,相邻两个防雨机构中同一层的排水槽3之间也可以相互平行。即相邻的两个防雨机构其最上层的百叶片和排水槽3的形状均相同且相互平行,中间层的百叶片和排水槽3的形状均相同相互平行,最下层的百叶片和排水槽3的形状均相同也相互平行。The shapes of the louvers 2 and the drain groove 3 on the two adjacent rainproof mechanisms are the same, and the louvers 2 on the same layer in the two adjacent rainproof mechanisms are parallel to each other, and the same in the two adjacent rainproof mechanisms The drainage grooves 3 of the layers may be parallel to each other. That is, the shapes of the uppermost louvers and the drain groove 3 of the two adjacent rainproof mechanisms are the same and parallel to each other, and the shapes of the louvers and the drain groove 3 of the middle layer are the same and parallel to each other. The shapes of the water tanks 3 are all the same and parallel to each other.
进一步的,同一个防雨机构中至少有相邻的上下两层百叶片2的倾斜方向相反或倾斜角度不同。Further, at least two adjacent upper and lower louvers 2 in the same rainproof mechanism have opposite tilt directions or different tilt angles.
作为一种方案,同一个防雨机构中的其中一层的百叶片2与水平面垂直而其余各层的百叶片2则与水平面形成锐角,如图12所示。As a solution, the louvers 2 of one layer in the same rainproof mechanism are perpendicular to the horizontal plane and the louvers 2 of the remaining layers form an acute angle with the horizontal plane, as shown in FIG. 12.
作为一种优选方案,如图23所示,一个所述防雨机构中包含有至少三层百叶片2,且在同一个防雨机构中,该百叶片2上端与其上一层的排水槽3相连,从而使得该防雨机构形成整体结构;具体的,百叶片2上端与其上一层的排水槽3的左侧或右侧或中部连接,其连接位置可以根据实际情况进行设置;在本方案中一个雨机构设置三层百叶片2。As a preferred solution, as shown in FIG. 23, one of the rainproof mechanisms includes at least three layers of louvers 2, and in the same rainproof mechanism, the upper end of the louvers 2 and the drainage groove 3 on the upper layer Connected, so that the rainproof mechanism forms an overall structure; specifically, the upper end of the louver 2 is connected to the left or right side or the middle of the drainage groove 3 of the upper layer, and the connection position can be set according to the actual situation; in this solution One rain mechanism has three louvers 2.
作为另一种优选方案,如图1、11、16所示,所述百叶片2与水平面形成锐角α,并且同一层的百叶片2的下端与排水槽3中靠近该百叶片2的一侧壁上端连接或位于排水槽3中靠近该百叶片2一侧的侧壁的上方或伸入到排水槽3中,而排水槽3中远离该百叶片2一侧的侧壁上端则位于与该百叶片2的垂直距离为X且与该百叶片2平行的平面上,如图16所示;或排水槽3中远离该百叶片2一侧的侧壁上端则位于与该百叶片2的垂直距离为X且与该百叶片2平行的平面的下方,如图17所示;本实施例中,30°≤α≤80°;X=N*sinα-N*0.45,其中N为相邻两片百叶片之间的水平距离,可以跟据排烟窗的长度自行设置。As another preferred solution, as shown in FIGS. 1, 11, and 16, the louver 2 forms an acute angle α with the horizontal plane, and the lower end of the louver 2 of the same layer and the side of the drain groove 3 near the louver 2 The upper end of the wall is connected or located above the side wall of the drain groove 3 close to the louver 2 side or extends into the drain groove 3, and the upper end of the side wall of the drain groove 3 away from the louver 2 side is located The vertical distance of the louver 2 is X and parallel to the louver 2, as shown in FIG. 16; or the upper end of the side wall of the drain groove 3 away from the louver 2 is located perpendicular to the louver 2 Below the plane where the distance is X and parallel to the louver 2, as shown in FIG. 17; in this embodiment, 30°≤α≤80°; X=N*sinα-N*0.45, where N is two adjacent The horizontal distance between the louvers can be set according to the length of the smoke exhaust window.
作为另一种优选方案,如图1所示,该百叶片2上设置有加强筋4,和/或百叶片2的上端部形成一个或一个以上的成弯折部6,如此则可以提高百叶片2的强度。As another preferred solution, as shown in FIG. 1, the louver 2 is provided with reinforcing ribs 4, and/or the upper end of the louver 2 forms one or more bending portions 6, so that the louver 2 can be increased. The strength of the blade 2.
在上述结构中,相邻两个防雨机构的同一层的两片百叶片2之间及同一层的两个排水槽3之间则形成通风风道;在计算通风风道的最小通风面积时实际是以排水槽3中远离该百叶片2一侧的侧壁上端到与该排水槽3相邻的百叶片2的垂直距离L、相邻两个排水槽3之间的垂直距离M、相邻两片百叶片2之间的垂直距离H、以及折弯部的端点到相邻百叶片的最短的垂直距离K中的最小值进行计算这个通风风道的宽度,通风风道的宽度再乘以此通风风道的长度则 等于此通风风道的有效通风面积,所有的通风风道的有效通风面积之和就是此百叶排烟窗的有效通风面积。如图18~21所示,在本实施例中设置M≥L,且H≥L,K≥L,该M、H、L、K的具体值可根据实际进行设置,因此本实施例中是以排水槽3中远离该百叶片2一侧的侧壁上端到与该排水槽3相邻的百叶片2的垂直距离L进行计算通风风道的有效通风面积比率e。In the above structure, a ventilation duct is formed between two louvers 2 on the same layer of two adjacent rain protection mechanisms and between two drainage grooves 3 on the same layer; when calculating the minimum ventilation area of the ventilation duct Actually, the vertical distance L from the upper end of the side wall of the drain groove 3 away from the louver 2 to the louver 2 adjacent to the drain groove 3, the vertical distance M between two adjacent drain grooves 3, the phase The vertical distance H between two adjacent louvers 2 and the minimum value of the shortest vertical distance K between the end of the bending part and the adjacent louvers are calculated to calculate the width of the ventilation duct, and then multiply the width of the ventilation duct In this way, the length of the ventilation duct is equal to the effective ventilation area of the ventilation duct, and the sum of the effective ventilation areas of all the ventilation ducts is the effective ventilation area of the louver smoke exhaust window. As shown in FIGS. 18 to 21, in this embodiment, M≥L, and H≥L, K≥L, the specific values of M, H, L, and K can be set according to the actual situation, so in this embodiment is The effective ventilation area ratio e of the ventilation duct is calculated from the vertical distance L of the upper end of the side wall of the drain groove 3 away from the louver 2 to the louver 2 adjacent to the drain groove 3.
另外,两片百叶片之间的垂直距离H=N*sinα,由上述公式可知,当N值固定时,α角度越大,两片百叶片之间的垂直距离H则越大,垂直距离X=N*sinα-N*0.45也越大,当M≥L、H≥L、K≥L,且排水槽3中远离该百叶片2一侧的侧壁上端位于与该百叶片2的垂直距离为X且与该百叶片2平行的平面下方时,通风风道所能达到的有效通风面积比率e则越大。In addition, the vertical distance between two louvers is H=N*sinα. According to the above formula, when the value of N is fixed, the larger the angle of α, the greater the vertical distance H between the two louvers, the vertical distance X =N*sinα-N*0.45 is also greater, when M≥L, H≥L, K≥L, and the upper end of the side wall of the drain groove 3 away from the louver 2 is located at a vertical distance from the louver 2 When it is X and is below the plane parallel to the louver 2, the effective ventilation area ratio e that the ventilation duct can achieve is greater.
当M≥L,且H≥L,K≥L,通风风道的有效通风面积(最小通风面积)=排水槽中远离百叶片一侧的侧壁上端到与该排水槽相邻的百叶片的垂直距离L×通风风道的长度,通风风道的面积=相邻两片百叶片之间的水平间距N×通风风道的长度,通风风道的有效通风面积比率e(即水平百叶排烟窗的有效通风面积比率)=通风风道的最小通风面积÷通风风道的面积,X=N*sinα-N*0.45;由上述公式及附图18~21可知,当排水槽3中远离百叶片2一侧的侧壁上端位于与该百叶片2的垂直距离为X且与该百叶片2平行的平面上时,排水槽中远离该百叶片一侧的侧壁上端到与该排水槽相邻的百叶片的垂直距离L是最小的,当相邻两片百叶片之间的水平间距N确定的情况下,此时通风风道的有效通风面积比率e是最小的;当排水槽3中远离该百叶片2一侧的侧壁上端位于与该百叶片2的垂直距离为X且与该百叶片2平行的平面下方时,排水槽中远离该百叶片一侧的侧壁上端到与该排水槽相邻的百叶片的垂直距离L相应增大,当M≥L,且H≥L,K≥L且相邻两片百叶片之间的水平间距N确定情况下,通风风道的有效通风面积比率e则相应增大。When M≥L, and H≥L, K≥L, the effective ventilation area of the ventilation duct (minimum ventilation area) = the upper end of the side wall of the drainage groove away from the louver side to the louver adjacent to the drainage groove Vertical distance L × length of ventilation duct, area of ventilation duct = horizontal spacing between two adjacent louvers N × length of ventilation duct, ratio of effective ventilation area of ventilation duct e (ie horizontal louver smoke exhaust The effective ventilation area ratio of the window) = the minimum ventilation area of the ventilation duct ÷ the area of the ventilation duct, X = N*sinα-N* 0.45; as can be seen from the above formula and figures 18 to 21, when the drain 3 is far from 100 When the upper end of the side wall of the blade 2 is located on a plane parallel to the louver 2 at a vertical distance of X from the louver 2, the upper end of the side wall of the drain groove away from the louver side is opposite to the drain groove The vertical distance L of the adjacent louver is the smallest. When the horizontal distance N between the adjacent two louvers is determined, the effective ventilation area ratio e of the ventilation duct is the smallest; when the drain groove 3 When the upper end of the side wall away from the louver 2 is located at a vertical distance X from the louver 2 and parallel to the louver 2, the upper end of the side wall in the drain groove away from the louver 2 reaches The vertical distance L of the louvers adjacent to the drainage channel increases accordingly. When M ≥ L, and H ≥ L, K ≥ L and the horizontal distance N between the two adjacent louvers is determined, the effective air duct The ventilation area ratio e increases accordingly.
根据上述公式,以下用实验例对通风风道的有效通风面积比率e进行说明:According to the above formula, the following describes the effective ventilation area ratio e of the ventilation duct with an experimental example:

表1Table 1
根据表1和附图18~21所示,实验例4的排水槽3中远离该百叶片2一侧的侧壁上端位于与该百叶片2的垂直距离为X=N*sina-N*0.45且与该百叶片2平行的平面上,根据上述可知,此时通风风道的有效通风面积比率e是最小的,其为45%;实验例1、2、3、5的排水槽3中远离该百叶片2一侧的侧壁上端位于与该百叶片2的垂直距离为X且与该百叶片2平行的平面的下方,其通风风道的有效通风面积比率e较实验例4中的通风风道的有效通风面积比率e有所增大。由此可见本实施例中的通风风道的有效通风面积比率e(即水平百叶排烟窗的有效通风面积比率)e≥45%,其与传统的通风器相比具有明显的通风优势。According to Table 1 and FIGS. 18 to 21, the upper end of the side wall of the drain groove 3 of the experimental example 4 away from the louver 2 is located at a vertical distance from the louver 2 of X=N*sina-N*0.45 And on the plane parallel to the louver 2, according to the above, the effective ventilation area ratio e of the ventilation duct at this time is the smallest, which is 45%; the drainage groove 3 of the experimental examples 1, 2, 3, and 5 is far away The upper end of the side wall of the louver 2 is located below the plane at a vertical distance X from the louver 2 and parallel to the louver 2, and the effective ventilation area ratio e of the ventilation duct is higher than that of the experimental example 4 The effective ventilation area ratio e of the air duct has increased. It can be seen that the effective ventilation area ratio e of the ventilation duct in this embodiment (that is, the effective ventilation area ratio of the horizontal louver smoke exhaust window) e ≥ 45%, which has obvious ventilation advantages compared with the traditional ventilator.
具体的,当百叶片2的下端与排水槽3中靠近该百叶片2的一侧壁上端连接时,二者可以为一体成型。通过百叶片2与排水槽3的上述设计,可以便于将雨水引流到排水槽3中,也可以确保水平百叶排烟窗的有效通风面积。Specifically, when the lower end of the louver 2 is connected to the upper end of a side wall close to the louver 2 in the drain groove 3, the two may be integrally formed. Through the above-mentioned design of the louver 2 and the drainage groove 3, the rainwater can be easily drained into the drainage groove 3, and the effective ventilation area of the horizontal louver smoke exhaust window can also be ensured.
具体的,如图14、15所示,所述弯折部6包括与百叶片2上端连接的第一折边61,与第一折边61连接的第二折边62。Specifically, as shown in FIGS. 14 and 15, the bent portion 6 includes a first folded edge 61 connected to the upper end of the louver 2 and a second folded edge 62 connected to the first folded edge 61.
进一步的,本实施例还可以设置第三折边63,该第三折边63与第二折边62连接。Further, in this embodiment, a third hem 63 may be provided, and the third hem 63 is connected to the second hem 62.
再进一步的,所述第一折边61和/或第二折边62和/或第三折边63呈弧形或呈水平设置;或者,所述第一折边61和/或第二折边62和/或第三折边63中远离或靠近百叶片2的一端向下倾斜设置。除最下层的排水槽3外,其余的每个排水槽3边缘的垂直投影均落在其下方的弯折部6的第一折边61和/或第二折 边62和/或第三折边63上;由上述结构,当排水槽3边缘处的水滴滴落到其下方的弯折部6的第一折边61和/或第二折边62和/或第三折边63上时会沿百叶片2流入到百叶片2下端的排水槽3内,而不至于产生大量的溅雨;另外,由于第一折边61和/或第二折边62和/或第三折边63远离或靠近百叶片2的一端向下倾斜,当排水槽3边缘处的水滴滴落到其下一层的第一折边61和/或第二折边62和/或第三折边63上后可能会向相应的一侧飞溅(由雨滴的大小、上部水槽距离折边的距离、折边的角度确定),控制向下倾斜的方向,能控制飞溅的方向,若产生飞溅,则控制飞溅的雨水掉落到相邻的百叶片2上或排水槽3内,这样则有效的防止了排水槽3上的水滴滴落时因飞溅而落入到室内。Still further, the first hem 61 and/or the second hem 62 and/or the third hem 63 are curved or horizontally arranged; or, the first hem 61 and/or the second hem One end of the side 62 and/or the third flange 63 that is far away from or close to the louver 2 is inclined downward. Except for the lowermost drainage channel 3, the vertical projection of the edge of each remaining drainage channel 3 falls on the first fold 61 and/or the second fold 62 and/or the third fold of the bend 6 below it On the edge 63; by the above structure, when the water droplets at the edge of the drainage groove 3 drip onto the first folded edge 61 and/or the second folded edge 62 and/or the third folded edge 63 of the bent portion 6 below it Will flow into the drainage groove 3 at the lower end of the louver 2 along the louver 2 without generating a lot of splashing rain; in addition, due to the first hem 61 and/or the second hem 62 and/or the third hem 63 The end away from or close to the louver 2 is inclined downward, when the water droplets at the edge of the drainage groove 3 drip onto the first fold 61 and/or the second fold 62 and/or the third fold 63 of the next layer Afterwards, it may splash to the corresponding side (determined by the size of the raindrops, the distance from the upper sink to the flange, and the angle of the flange). Control the direction of the downward slope, which can control the direction of the splash. The rainwater falls on the adjacent louver 2 or the drainage groove 3, which effectively prevents the water droplets on the drainage groove 3 from falling into the room due to splashing when they drop.
进一步的,在同一个防雨机构中除最下层的排水槽3及百叶片2外,至少有一层百叶片2及其对应的排水槽3的外边缘的垂直投影均落在其下一层的百叶片2上或其下一层百叶片2的弯折部6上或其下一层的水槽3中。由上述结构,当雨水落到最上层的百叶片2上时,雨水沿着该百叶片流入到其下端的排水槽3,如果该排水槽3内的雨水溢满,则雨水会掉落到下一层的百叶片上,再由该下一层百叶片下端的排水槽排走,经过层层阻挡,雨水则无法流入到室内;通过设置多层排水槽可以提高本发明的排水能力。Further, in the same rain protection mechanism, except for the lowermost drain groove 3 and the louver 2, at least one layer of louver 2 and the corresponding vertical projection of the outer edge of the drain groove 3 fall on the next layer The louver 2 or the layer below it is in the sink 3 on the bent part 6 of the louver 2 or below it. With the above structure, when the rainwater falls on the uppermost louver 2, the rainwater flows along the louver into the drain groove 3 at the lower end thereof. If the rainwater in the drain groove 3 is full, the rainwater will fall down The louvers of the first layer are drained by the drainage groove at the lower end of the louvers of the next layer. After being blocked by the layers, the rainwater cannot flow into the room; the drainage capacity of the present invention can be improved by providing the multilayer drainage grooves.
进一步的,本实施例中任意一层或多层百叶片2上边缘的垂直投影落在其同一层相邻的百叶片2或同一层相邻的排水槽3中;如此,水雾在最下方百叶片的上沿形成的水滴则会滴落在同一层相邻的百叶片2或同一层相邻的排水槽3上,而不会从两片百叶片之间直接滴落到室内,提高了本发明的防雨效果。Further, in this embodiment, the vertical projection of the upper edge of any one or more louvers 2 falls on the adjacent louvers 2 in the same layer or the adjacent drainage groove 3 in the same layer; thus, the water mist is at the bottom The water droplets formed on the upper edge of the louver will drop on the adjacent louver 2 on the same layer or the adjacent drainage groove 3 on the same layer, and will not directly drop into the room from between the two louvers. The rainproof effect of the present invention.
作为另一种优选方案,任意一层或多层排水槽3的边沿和/或百叶片2的下端边沿的垂直投影落在最下层百叶片2上,从而防止排水槽3的边沿或百叶片2的下端边沿上的水滴滴落到最下层排水槽3内而引起雨水飞溅,落入到室内。As another preferred solution, the vertical projection of the edge of any one or more layers of drain grooves 3 and/or the lower edge of the louver 2 falls on the lowermost louver 2, thereby preventing the edge of the drain groove 3 or the louver 2 The water droplets on the lower edge of the drop fall into the lowermost drain groove 3 to cause rainwater to splash and fall into the room.
作为一种优选方案,任意一个或多个防雨机构中最下层的排水槽3为承力水槽8,所述承力水槽8的下沿低于其余最下层的排水槽3的下沿,如图5、6所示。使用时该承力水槽8与基座固定,本实施例中防雨机构最下层的排水槽3与承力水槽8相互间隔设置。As a preferred solution, the lowermost drain groove 3 in any one or more rain prevention mechanisms is a bearing water tank 8, and the lower edge of the bearing water tank 8 is lower than the lower edges of the remaining lowermost drain grooves 3, such as Figures 5 and 6 show. The load-bearing water tank 8 is fixed to the base during use, and the drain groove 3 and the load-bearing water tank 8 in the lowermost layer of the rainproof mechanism in this embodiment are spaced apart from each other.
具体的,如图7、8所示,该承力水槽8包括槽体81,连接在槽体81上端部的支撑部82;该支撑部82可以设置为两个,两个支撑部82的弯折方向可以相同或相反。Specifically, as shown in FIGS. 7 and 8, the bearing water tank 8 includes a tank body 81 and a support portion 82 connected to the upper end of the tank body 81; the support portion 82 may be provided as two, and the two support portions 82 are bent The folding direction can be the same or opposite.
相应的,如图3、6所示,该支撑骨架1上设置有承力水槽安装孔7,该承力水槽安装孔7可以用于安装承力水槽;因此,该承力水槽安装孔7的位置与承力水槽8的位置相对应。如图3、4所示,该承力水槽安装孔7内开设有与支撑部82相配合的凹槽71,当承力水槽8安装在承力水槽安装孔7内时,支撑部82则伸入到凹槽71内。承力水槽安装孔7的下部可以是封闭的,如图3所示;另外,如图4所示,该承力水槽安装孔7的下端还可以与支撑骨架1的下沿持平,即该承力水槽安装孔7的下部可以是敞开的如图4、5所示,因此承力水槽8安装在承力水槽安装孔7上后,其下端可以与支撑骨架1的下沿持平,使得承力水槽8起更好的支撑作用。Correspondingly, as shown in FIGS. 3 and 6, the supporting frame 1 is provided with a bearing sink installation hole 7, which can be used to install the bearing sink; therefore, the bearing sink installation hole 7 The position corresponds to the position of the bearing sink 8. As shown in FIGS. 3 and 4, the bearing trough installation hole 7 is provided with a groove 71 matching the support portion 82. When the bearing trough 8 is installed in the bearing trough installation hole 7, the support portion 82 extends Into the groove 71. The lower part of the load-bearing sink installation hole 7 may be closed, as shown in FIG. 3; in addition, as shown in FIG. 4, the lower end of the load-bearing sink installation hole 7 may also be flat with the lower edge of the support frame 1, that is, the bearing The lower part of the force sink installation hole 7 may be open as shown in FIGS. 4 and 5, so after the force sink 8 is installed on the force sink installation hole 7, its lower end can be level with the lower edge of the support frame 1 to make the load bearing The sink 8 plays a better supporting role.
如图5、6所示,该承力水槽安装孔7下端形成喇叭口,即承力水槽安装孔7的下端直径大于上端直径,如此则方便承力水槽8的安装。该承力水槽8能够排水外还可以起承力作用,其能够承受支撑骨架、百叶片、排水槽、以及在使用时落在百叶片上的风雪的载荷。该承力水槽8需采用较厚的材料制作,其材料厚度需比排水槽3的材料厚度更厚,其分担了支撑骨架所承受的重力,在具体安装时可以减少基座的数量,降低成本。As shown in FIGS. 5 and 6, a trumpet is formed at the lower end of the bearing slot installation hole 7, that is, the diameter of the lower end of the bearing slot installation hole 7 is larger than the diameter of the upper end, which facilitates the installation of the bearing slot 8. The load-bearing water tank 8 can not only drain water but also play a load-bearing role, and it can bear the load of the supporting frame, the louver, the drain groove, and the wind and snow falling on the louver in use. The load-bearing water tank 8 needs to be made of a thicker material, and its material thickness needs to be thicker than the material thickness of the drainage tank 3, which shares the gravity supported by the supporting frame, which can reduce the number of bases and reduce costs during specific installation .
