Description

Changer rain insensitive device

Technical Field

The invention relates to a rainproof device, in particular to a transmitter rainproof device.

Background

Transmitters have evolved from sensors, all of which are capable of outputting a standard signal. The standard signal is a signal having a form and quantity in a range conforming to the international standard. The transducer works based on the principle of negative feedback and mainly comprises a measuring part, an amplifier and a feedback part.

The transmitter of power plant is used extensively and a very big part changer is all installed outdoors, and the changer is owing to lack corresponding rain insensitive device, uses after a period, and inside the rainwater can get into the changer through changer connection gap to influence the normal work of changer.

Based on above-mentioned problem, this application provides a changer rain insensitive device.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a transmitter rainproof device.

The invention is realized by the following technical scheme, and provides a transmitter rainproof device which comprises a transmitter arranged on a pipeline, wherein hoops are respectively arranged on the pipeline on the left side and the right side of the transmitter, a fixed seat is fixedly arranged on each hoop, a guide rod is arranged on each fixed seat, and two ends of a mounting plate are respectively connected with the upper ends of the two guide rods; the rain cover is buckled on the transmitter, the screw rod is in threaded connection with the mounting plate, the upper end of the screw rod is fixedly connected with the handle, and the lower end of the screw rod is connected with the top surface of the rain cover through a bearing; all sliding connection a slide on every guide bar, the one end that the guide bar was kept away from to every slide all with rain-proof cover rigid coupling.

Preferably, a polyurethane heat-insulating layer is arranged on the inner wall of the rain-proof cover.

Preferably, the side wall of the rain cover is provided with a vent hole, a rain shield is fixedly connected to the rain cover, and the vent hole is shielded by the rain shield.

Preferably, a threaded hole is formed in the fixed seat, and the guide rod is in threaded connection with the fixed seat.

Preferably, the mounting plate and the guide bar are fixed by screws.

The invention has the beneficial effects that:

1. the lifting of the rain-proof cover can be realized by rotating the handle, and the rain-proof cover is lifted when the transmitter needs to be overhauled and maintained. And after the maintenance is finished, the rain cover is lowered, and the transmitter is buckled by the rain cover to achieve a rain-proof effect.

2. Simple structure, the dismouting is nimble, and it is effectual to rain-proof, has promoted the life of changer greatly.

Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.

As shown in figure 1, the invention comprises a transmitter 11 arranged on a pipeline 1, clamps 2 are respectively arranged on the pipeline 1 at the left side and the right side of the transmitter 11, a fixed seat 3 is fixedly arranged on each clamp 2, a guide rod 4 is arranged on each fixed seat 3, and two ends of a mounting plate 6 are respectively connected with the upper ends of the two guide rods 4. Rain-proof cover 9 is detained on changer 11, and lead screw 7 and mounting panel 6 threaded connection, the upper end and the handle 8 rigid coupling of lead screw 7, and the lower extreme of lead screw 7 is connected with the top surface of rain-proof cover 9 through the bearing. All sliding connection slide 5 on every guide bar 4, the one end that guide bar 4 was kept away from to every slide 5 all with rain-proof cover 9 rigid coupling. In the present embodiment, the slide 5 is provided with a through hole through which the guide bar 4 passes.

In this embodiment, a polyurethane insulating layer 10 is disposed on an inner wall of the rain cover 9, and the polyurethane insulating layer 10 can enhance the heat insulating effect of the rain cover 9.

In this embodiment, a vent hole 12 is formed in a side wall of the rain cover 9, a rain shield 13 is fixedly connected to the rain cover 9, and the vent hole 12 is shielded by the rain shield 13. Vent hole 12 can satisfy the ventilation needs of transmitter 11, and the setting of weather shield 13 can avoid ventilation hole 12 department to intake.

In this embodiment, be equipped with the screw hole on fixing base 3,

guide bar

4 and 3 threaded connection of fixing base. The guide rod 4 can be flexibly disassembled according to requirements.

In this embodiment, the mounting plate 6 is fixed to the guide bar 4 by screws 14. The mounting plate 6 and the guide rod 4 can be assembled and combined flexibly.
