Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In the specific implementation: with reference to figure 1 of the drawings,

a mobile tritium monitor rain-proof structure comprises a tritium monitor box body 1, wherein an air inlet 6 is formed in a bottom plate of the box body 1, and an air outlet 2 is formed in a rear side plate of the box body 1; be equipped with guide plate 3 in the inboard of posterior lateral plate, the clearance has between guide plate 3 and the posterior lateral plate, the downside of guide plate 3 is to the direction bending type bottom baffle of posterior lateral plate, and its relative both sides are to the direction bending type lateral part baffle that is close to the posterior lateral plate, the bottom baffle is located 2 below of air exit, and both sides portion baffle is located the outside of 2 both sides of air exit, and bottom baffle and lateral part baffle all with the sealed fixed connection of posterior lateral plate, air exit 2 can communicate with each other with 1 inside of box through the clearance between 3 upsides of guide plate and the posterior lateral wall. Air exit 2 includes a plurality of honeycomb holes that are rectangle or circular or hexagon and distribute, and is corresponding, the bottom plate of guide plate 3 is rectangle or circular or trapezoidal, just the upside of the bottom baffle of guide plate 3 and the downside parallel and level that is located the honeycomb hole of below for the upside of bottom baffle forms the guiding gutter, gets into the guiding gutter through the interception of bottom plate of the rainwater that air exit 2 got into 1 inside of box, and flows through the honeycomb hole of below and bottom baffle parallel and level of air exit 2, thereby guarantees the high-efficient discharge of rainwater, in order to guarantee the inside dry environment of equipment.

For the drainage efficiency of the rainwater that further improvement got into in the equipment, the bottom baffle slope setting of guide plate 3 makes the bottom baffle keep away from the one end of curb plate is higher than the other end, makes the rainwater that gets into in the guide plate 3 can flow through honeycomb hole faster.

In order to ensure a certain heat dissipation effect, the bottom plate of the flow guide plate 3 is obliquely arranged, so that the distance between the upper end of the bottom plate and the side plates is greater than the distance between the lower end of the bottom plate and the side plates, an opening with a certain expansion degree is formed between the flow guide plate 3 and the side plates, the heat dissipation air quantity is ensured, and a certain heat dissipation effect is ensured.

In order to further prevent rainwater entering the flow guide plate 3 from splashing into the box body 1, a splash guard 4 is further arranged above the flow guide plate 3, one side of the splash guard 4 is connected with the side plate, the other side of the splash guard is bent towards the direction close to the bottom plate of the flow guide plate 3, a gap is formed between the side of the splash guard 4 and the bottom plate of the flow guide plate 3, and the horizontal projection of the splash guard 4 is matched with the open side of the flow guide plate 3. Specifically, 4 levels of splash guard set up, its one end of buckling is buckled downwards, and this end has certain clearance with the tip of bottom plate, in order to guarantee normal air volume, and one side lower limb that one end of should buckling is close to the curb plate is located the open side inside of guide plate 3 at least in the projection of horizontal plane, so when the rainwater that sputters on splash guard 4 assembles the end of buckling, can be smooth instil into in the open side of guide plate 3, thereby flow in by guiding gutter and cellular hole again, thereby better assurance 1 inside rains not of box, higher rain-proof effect has.

Based on the aforesaid prevent structure of drenching with rain, the utility model also provides a portable tritium monitor, including tritium monitor box 1 be equipped with in the box 1 tritium monitor prevents the structure of drenching with rain during removal, and be equipped with ionization chamber and dry-type pump 5 in the box 1, the ionization chamber is located as the projection position rear side of the dry-type pump 5 shown in fig. 1, dry-type pump 5 links to each other with the ionization chamber for with tritium air suction ionization in the ionization chamber, with measurement tritium concentration, air exit 2 is just to dry-type pump 5, and air intake 6 has been seted up to the bottom of box 1, just installs ventilation fan 7 to the position of air intake 6 in box 1, the inlet end and the air intake 6 of fan 7 communicate with each other, and the end of giving vent is just to dry-type pump 5. Because the dry pump 5 is installed in the tritium monitor to provide power demand for the work of the ionization chamber of the whole equipment, but the dry pump 5 generates heat seriously and needs ventilation and heat dissipation, so in the structural installation design stage of the dry pump 5, a fan 7 is installed at the bottom of the whole equipment corresponding to the projection of the dry pump 5, external air is sucked from the lower part of the box body 1 and blows upwards towards the dry pump 5, the whole machine is sealed, so that the external air sucked by the fan 7 at the bottom is blown into the box body 1 through the dry pump 5, because of the positive pressure reason in the box body 1, hot air is removed from the residual air through the rear cover plate of the tritium monitor projected by the dry pump 5, and the ventilation and convection cooling effects are achieved.

The utility model discloses improve on structural design, inside the method through the dual fail-safe prevents that the rainwater from getting into the equipment box to the guiding gutter that forms through the guide plate bottom plate can be with the rainwater drainage equipment box that gets into the guide plate, makes equipment not influenced normal work under the rain condition. The application provides a tritium monitor, through lower extreme fan suction air, the ventilation method that the rear side was got rid of has the advantage: firstly, the density of cold air is higher than that of hot air, so that the rear opening exhausts air and the lower opening sucks air, and the hot air above is exhausted preferentially; the second step is as follows: the method for sucking air from the lower opening can ensure that the air sucked from the lower opening is drier; and thirdly: the rear side opening exhaust is just in the state of positive pressure at the inner side, so that rainwater entering the honeycomb holes can be further discharged by positive pressure, and the interior of the equipment is further prevented from being influenced by rainwater.
