Description
技术领域 本实用新型涉及配电装置，特别涉及防爆环境下使用的防爆配电装置。Technical Field The utility model relates to a power distribution device, in particular to an explosion-proof power distribution device used in an explosion-proof environment.
背景技术 目前，易燃易爆场所中的防爆配电装置，常常由于隔爆面不能密封(因为需要泄压隔爆)，从而使防爆的配电产品并不能够防水，以往常用的方法是采用在防爆配电装置外加防雨/水罩或者是在隔爆面上开槽加橡胶条的方法来实现防水功能。这种方式的缺点在于，外加防雨罩的方法需要浪费额外材料，安装维护工序多，且容易遗漏，尤其是对于侧面的雨水侵害，几乎没有防护能力；采用在隔爆面上开圆槽外加橡胶条的方法同样需要浪费额外材料，橡胶易出现老化失效的情况，减弱其防水的效果。Background technology At present, explosion-proof power distribution devices in flammable and explosive places often cannot be sealed due to the explosion-proof surface (because of the need for pressure relief and explosion-proof), so that the explosion-proof power distribution products cannot be waterproof. In the past, the commonly used method is to use The method of adding a rainproof/water cover to the explosion-proof power distribution device or adding a rubber strip to the explosion-proof surface can realize the waterproof function. The disadvantage of this method is that the method of adding a rainproof cover needs to waste extra materials, and the installation and maintenance procedures are many, and it is easy to miss, especially for the rain on the side, there is almost no protection; The rubber strip method also needs to waste extra materials, and the rubber is prone to aging and failure, which weakens its waterproof effect.
实用新型内容 本实用新型提供一种带简易防水结构的防爆配电装置，采用在防爆面上开简易防水槽的方式，解决现有技术中存在的防雨/水罩防水效果不好以及橡胶密封易老化失效的技术问题。The content of the utility model The utility model provides an explosion-proof power distribution device with a simple waterproof structure, which adopts the method of opening a simple waterproof groove on the explosion-proof surface to solve the problems in the prior art that the waterproof effect of the rainproof/water cover is not good and the rubber seal Technical problems that are prone to aging and failure.
本实用新型实现上述发明目的的方案是：设计一种带简易防水结构的防爆配电装置，包括开口箱形的后罩体，前封盖覆盖该开口，电器控制部置于前封盖与后罩体之间形成的空腔内，所述后罩体围绕空腔周边侧壁与前封盖之间存有气隙；所述后罩体侧壁与前封盖相对的侧壁端面上设有第一凹槽，该第一凹槽由空腔顶部侧壁开始，向两边延伸，其截止处低于空腔的最低点；所述前封盖与后罩体侧壁端面相对的内端面上也设有与第一凹槽相对应的第二凹槽；所述第一凹槽和第二凹槽靠近空腔一侧的侧壁上设有向空腔方向凹入的集水凹槽；所述第一凹槽远离空腔一侧的与侧壁端面相邻的第一侧壁表面或其表面切线与侧壁端面的夹角为钝角；所述第二凹槽远离空腔一侧的与内端面相邻的第二侧壁表面或其表面切线与内端面的夹角为钝角。本实用新型的工作原理是，当有雨水进入后罩体与前封盖之间的气隙中后，由于该气隙比较小，所以，雨水不可能直接灌入，而是沿后罩体周边侧壁端面和前封盖端面慢慢向下流动，当水滴流动第一凹槽和第二凹槽上沿时，由于第一凹槽和第二凹槽在这个部位的侧壁与其相邻面成钝角，所以，水滴在这里将分成两部分，并分别沿第一凹槽和第二凹槽的侧壁流入第一凹槽和第二凹槽内，由于在第一凹槽和第二凹槽靠近空腔一侧的侧壁上设有集水凹槽，这样就会使流入的水滴被滞留在该集水凹槽内，由于该集水凹槽在靠近气隙一侧也有一个档水边的存在，所以，滞留在集水凹槽内的雨水就不会向气隙一侧蔓延。当雨水积累比较多的时候，集水凹槽内的雨水会沿该凹槽向两侧流动，并最终被排出，由于，集水凹槽截止处低于空腔的最低点，所以，排出的雨水也不会侵入后罩体的空腔内，从而可以保护设置于该空腔内的电器部件，起到了防水的功能。The solution of the utility model to realize the purpose of the above invention is to design an explosion-proof power distribution device with a simple waterproof structure, which includes an open box-shaped rear cover body, the front cover covers the opening, and the electrical control unit is placed between the front cover and the rear cover. In the cavity formed between the covers, there is an air gap between the side wall surrounding the cavity and the front cover of the rear cover; There is a first groove, which starts from the top side wall of the cavity and extends to both sides, and its cut-off point is lower than the lowest point of the cavity; the inner end surface of the front cover opposite to the end surface of the rear cover side wall There is also a second groove corresponding to the first groove; the side wall of the first groove and the second groove near the cavity is provided with a water collection groove concave toward the cavity ; The angle between the first side wall surface adjacent to the side wall end face of the first groove away from the cavity side or its surface tangent and the side wall end face is an obtuse angle; the second groove is far away from the cavity side The included angle between the surface of the second side wall adjacent to the inner end surface or its surface tangent and the inner end surface is an obtuse angle. The working principle of the utility model is that when rainwater enters the air gap between the rear cover body and the front cover, since the air gap is relatively small, it is impossible for the rainwater to be directly poured in, but to be poured along the periphery of the rear cover body. The end face of the side wall and the end face of the front cover slowly flow downward. When the water droplets flow on the upper edge of the first groove and the second groove, because the side wall and the adjacent surface of the first groove and the second groove at this position form an obtuse angle, so the water drop will be divided into two parts here, and flow into the first groove and the second groove along the sidewalls of the first groove and the second groove respectively, because the first groove and the second groove There is a water collecting groove on the side wall of the groove near the cavity, so that the inflowing water droplets will be trapped in the water collecting groove, because the water collecting groove also has a water retaining groove on the side near the air gap. Because of the existence of the edge, the rainwater stagnated in the water collecting groove will not spread to the side of the air gap. When the rainwater accumulates a lot, the rainwater in the water collecting groove will flow to both sides along the groove, and finally be discharged. Since the cut-off point of the water collecting groove is lower than the lowest point of the cavity, the discharged Rainwater will not intrude into the cavity of the rear cover, so that the electrical components arranged in the cavity can be protected, and the function of waterproofing is achieved.
本实用新型提供的带简易防水槽的防爆配电装置，摆脱了当前防爆配电装置需要配置额外的防雨罩或密封橡胶的做法，解决了因此带来的额外材料损耗、安装维护复杂、材料易老化和易遗漏的问题。同时，本实用新型的带简易防水槽的防爆配电装置可以与隔爆壳体一次铸造而成，不改变传统隔爆面的加工和使用工艺，具有结构简单、节省成本、生产和使用方便的特点。The explosion-proof power distribution device with a simple waterproof groove provided by the utility model gets rid of the current method that the explosion-proof power distribution device needs to be equipped with an additional rain cover or sealing rubber, and solves the extra material loss, complicated installation and maintenance, and material loss caused by it. Problems that are easy to age and easy to miss. At the same time, the explosion-proof power distribution device with a simple waterproof groove of the utility model can be cast together with the explosion-proof shell at one time, without changing the processing and use process of the traditional explosion-proof surface, and has the advantages of simple structure, cost saving, convenient production and use. features.

本实用新型的工作原理是，当有雨水进入后罩体10与前封盖40之间的气隙30中后，由于该气隙30比较小，所以，雨水不可能直接灌入，而是沿后罩体10周边侧壁端面12和前封盖端面41慢慢向下流，当水滴流动第一凹槽50和第二凹槽60上沿时，由于第一凹槽50和第二凹槽60在这个部位的侧壁52、62与其相邻面12、41成钝角，所以，水滴在这里将分成两部分，并分别沿侧壁52、62流入第一凹槽50和第二凹槽60内，由于在第一凹槽50和第二凹槽60靠近空腔11一侧的侧壁上设有集水凹槽51、61，这样就会使流入的水滴被滞留在该集水凹槽51、61内，由于该集水凹槽51、61在靠近气隙30一侧也有一个档水边的存在，所以，滞留在集水凹槽51、61内的雨水就不会向气隙30一侧蔓延。当雨水积累比较多的时候，集水凹槽51、61内的雨水会沿该凹槽向两侧流动，并最终被排出，由于，集水凹槽截止处低于空腔11的最低点，所以，排出的雨水也不会侵入后罩体10的空腔11内，从而可以保护设置于该空腔内电器控制部20的电器部件，起到了防水的功能。The working principle of the present utility model is that when rainwater enters the air gap 30 between the rear cover body 10 and the front cover 40, since the air gap 30 is relatively small, the rainwater cannot be directly poured in, but along the The end face 12 of the peripheral side wall of the rear cover 10 and the end face 41 of the front cover slowly flow downward. The sidewalls 52, 62 at this position form obtuse angles with their adjacent surfaces 12, 41, so the water drop will be divided into two parts here, and flow into the first groove 50 and the second groove 60 along the sidewalls 52, 62 respectively. Since the first groove 50 and the second groove 60 are provided with water collecting grooves 51, 61 on the side walls near the side of the cavity 11, the water droplets flowing in will be retained in the water collecting grooves 51 , 61, since the water collecting grooves 51, 61 also have a water retaining edge on the side near the air gap 30, so the rainwater staying in the water collecting grooves 51, 61 will not flow toward the air gap 30. side spread. When the rainwater accumulates a lot, the rainwater in the water-collecting grooves 51 and 61 will flow to both sides along the grooves, and finally be discharged, because the cut-off point of the water-collecting grooves is lower than the lowest point of the cavity 11, Therefore, the discharged rainwater will not intrude into the cavity 11 of the rear cover 10 , so that the electrical components arranged in the electrical control unit 20 in the cavity can be protected, and the function of waterproofing can be achieved.
