Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings 1 to 5.

In the first embodiment, when the cabinet is used, the cabinet body 1 is used for placing electrical equipment elements and equipment, and the cabinet door 2 is arranged to prevent the equipment in the cabinet body 1 from being stolen and facilitate maintenance work. When meeting with extreme weather such as rainstorm, the rainwater is very likely to enter into the cabinet body 1, and especially the cabinet body 1 with longer service time has poor waterproof effect, and the rainwater is easier to enter into the cabinet body 1. For avoiding entering into the rainwater in the cabinet body 1 to cause the harm to the equipment in the cabinet body 1, so be equipped with honeycomb duct 5 in the cabinet body 1 bottom can hold chamber 4 with the rainwater is leading-in, a plurality of honeycomb ducts 5 can be quick will get into the rainwater leading-in the cabinet body 1 and hold chamber 4, avoid the equipment in the rainwater harm cabinet body 1.

Embodiment two, on the basis of embodiment one, it is great at the rainwater, when the cabinet body 1 intakes fastly, for avoiding holding chamber 4 and leading to holding the rainwater in chamber 4 and pouring into cabinet body 1 because of holding full water, the event installs first check valve 19 on honeycomb duct 5, prevent to hold the rainwater in chamber 4 and pour into, more near further be equipped with drainage device, can be when the rainwater great timely will hold the rainwater in chamber 4 and discharge, avoid holding chamber 4 in the rainwater excessive influence cabinet body 1 safety. The concrete principle of the drainage device is as follows: when the rainwater is great, when the cabinet body 1 intakes water, water in the cabinet body 1 can enter the containing cavity 4 through the draft tube 5, the rainwater in the containing cavity 4 is gradually increased along with the lapse of time, and further the floating ball 13 floats upwards, the floating ball 13 floats upwards to drive the floating rod 12 to upwards move along the sleeve 11 fixedly connected with the connecting rod 10, the floating rod 12 upwards moves to drive the sealing plug 16 to upwards move along the waterproof cylinder 14 and compress the spring 17, the spring 17 is compressed to generate acting force on the pressure switch 15, the acting force reaches the set value of the pressure switch 15 to start the pressure switch 15, the pressure switch 15 is started to enable the drainage pump 7 to be installed, after the drainage pump 7 is started, the rainwater in the containing cavity 4 is pumped away through the water pumping pipe 8, and the rainwater is drained to a municipal pipe network through the drainage pipe 9. In order to prevent the drain pipe 9 from flowing backward through the drain pipe 9 when draining, a second check valve 21 is installed in the drain pipe 9. Along with drainage device work, the water yield reduces in the chamber 4, and floater 13 will drive float rod 12 and move down along sleeve 11, and float rod 12 drives sealing plug 16 again and moves down along waterproof section of thick bamboo 14, and then makes spring 17 expand, and pressure switch 15 receives the effort of spring 17 and reduces, and pressure switch 15 will self-closing when the effort that pressure switch 15 received is less than the setting value, and drainage device stops working.

Third embodiment, on the basis of second embodiment, in order to avoid floating ball 13 to drive floating rod 12 to produce when moving up along sleeve 11 and rotate and then make sealing plug 16 drive spring 17 and rotate wearing and tearing pressure switch 15, so set up a plurality of perpendicular grooves that encircle its axis equipartition on sleeve 11 inner wall, floating rod 12 outer fringe face fixedly connected with a plurality of with perpendicular groove one-to-one and vertical sliding fit's guide key 18, under the restriction in guide key 18 and perpendicular groove, floating rod 12 can only be along sleeve 11 vertical movement and can not produce the rotation.

The left and right sides of the upper end of the base 3 are provided with inclined slope structures 22, so that rainwater can be prevented from accumulating at the upper end of the base 3 and permeating into the cabinet body 1. The filtering net cover 20 can prevent impurities such as silt from entering the water pumping pipe 8 to cause blockage.
