Abstract
The invention relates to a protective cover used in a TSP sampler. The protective cover includes a waterproofing box body (1) of which one end is opened. A first through hole (2) is formed on the top surface of the box body (1) and a second through hole (3) is formed on the bottom surface of the box body (1). The three side surfaces of the box body (1) are respectively provided with heat dissipating holes (4). A waterproof plate is movably connected to a position, which is closed to the heat dissipating holes (4), of the box body (1). The top surface is stretched out outwardly to form a rain shield surface. A waterproof door curtain (5) is movably connected to a position, which is closed to the opening on the box body, of the box body (1). The waterproof door curtain (5) is made of a PVC transparent soft plate. In rainy day, the box body and the PVC transparent soft plate therein can prevent rain to be splashed into the sampler, thereby avoiding short circuit in the device. Under a hot weather, heat generated in operation of the sampler can be dissipated through the heat dissipating holes effectively.
Description
Technical field
The present invention relates to a kind of protective cover, especially a kind of protective cover for TSP sampling thief.
Background technology
TSP sampling thief is a kind of device measuring overall suspended pellet (comprising PM2.5 and PM10) in air for filter membrane weight method, for carrying out the comparison work of PM10 and PM2.5 content in air smoothly, needs in the continuous coverage in 24 hours of outdoor application TSP sampling thief.Existing TSP sampling thief self does not have the function of rainwater-proof and heat radiation, and in the rainy day, rainwater is very big on the impact of TSP sampling thief, and serious meeting damages sampling thief; At the fine day of sweltering heat, sunshine direct projection equipment produces heat, and can shorten the serviceable life of sampling thief, dispel the heat although some equipment has offered thermovent, rainwater is easily entered by thermovent thus damages instrument.
Summary of the invention
Object of the present invention is exactly the problem that the existing TSP sampling thief of solution can damage in rainy day or hot weather down-sampler.
The technical solution used in the present invention is: a kind of protective cover for TSP sampling thief, it comprises one end and is opening and can the casing of waterproof, the end face of casing is provided with the first through hole, the bottom surface of casing is provided with the second through hole, three sides of casing are respectively equipped with thermovent, the inwall of described casing is connected with waterproof door curtain near box opening, and described casing is connected with splash guard near thermovent place.
As a further improvement on the present invention, described waterproof door curtain is PVC transparent soft board.
As a further improvement on the present invention, the end face of described casing protruding formation rain cover face.
The beneficial effect that the present invention adopts is: after TSP sampling thief employs this protective cover, in the rainy day, and the PVC transparent soft board in casing and casing can prevent rainwater from splashing in sampling thief, avoids equipment to be short-circuited; At hot weather, heat when sampling thief runs can effectively be got rid of by thermovent.In sum, this protective cover makes TSP sampling thief also can normally work in rainy day or hot weather, extends the serviceable life of TSP sampling thief.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is the upward view of Fig. 1
Fig. 3 is that the present invention uses schematic diagram.
Shown in figure: 1, casing, the 2, first through hole, the 3, second through hole, 4, thermovent, 5, waterproof door curtain, 6, TSP sampling thief, 7, A-frame, 8, sampling head.
Embodiment
Below in conjunction with Fig. 1,2, the present invention is described further.
As shown in Figure 1, 2, preference of the present invention is: a kind of protective cover for TSP sampling thief, it comprises one end and is opening and can the casing 1 of waterproof, the end face of casing 1 is provided with the first through hole 2, the bottom surface of casing 1 is provided with the second through hole 3, three sides of casing 1 are respectively equipped with thermovent 4, the end face protruding formation rain cover face of described casing 1, the inwall of described casing 1 is connected with waterproof door curtain 5 near box opening, described waterproof door curtain 5 is PVC transparent soft board, and described casing 1 is connected with splash guard near thermovent 4 place.
After present invention employs this structure, in use, protective cover is fixedly connected on TSP sampling thief 6, by the front of TSP sampling thief 6 in the face of box opening, can be seen the data on sampling thief like this by PVC transparent soft board; The first through hole 2 on the end face of casing 1 is fixedly connected with the sampling head 8 of TSP sampling thief; The second through hole 3 on casing 1 bottom surface is connected with A-frame 7, for fixing TSP sampling thief; In the rainy day, the PVC transparent soft board in the described splash guard of casing 1 near thermovent 4 place, casing and casing can prevent rainwater from splashing in sampling thief, avoids equipment to be short-circuited; At hot weather, heat when sampling thief runs can effectively be got rid of by thermovent.In sum, this protective cover makes TSP sampling thief also can normally work in rainy day or hot weather, extends the serviceable life of TSP sampling thief.
Claims (3)
