Description
Technical Field
The utility model relates to the technical field of ventilation of valve wells, in particular to a ventilation device for a valve well.
Background
The operation in confined space such as valve well, because the airtight structure of valve well, ventilation condition is relatively poor, and inner structure is complicated, and the oxygen content is not enough in the air, or exists poisonous, harmful gas, probably makes operating personnel poisoning, choking etc. produce adverse effect to healthy, consequently need set up air purification device at the valve well head, replace wherein gas, conveniently overhaul the operation.
Various ventilation devices in the market at present are various and mainly comprise pipeline type, wall type, post type, fixed type and the like, but the ventilation devices special for valve wells are not available, so that the on-site installation and the use are difficult, and the ventilation effect is poor.
When operation such as fire is carried out in the valve well, need detect the replacement to the air in the well, the condition is complicated in the pit, and gas detector is fixed difficulty, and the noise is great, and guardianship personnel monitor the gaseous composition difficulty in the valve well, have certain potential safety hazard, and prior art can't solve above-mentioned technical problem.
Disclosure of Invention
The utility model aims to solve the problems of difficult ventilation of a valve well and fixation of a detector in the prior art, and provides a ventilation device for the valve well.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
a ventilation unit for valve well, includes the casing, and the inboard of casing is fixed with the motor, is fixed with the flabellum on the output shaft of motor, and the screen panel is equipped with in the both ends of casing all can be dismantled, and the outside middle part of casing is equipped with the connecting rod along the circumferencial direction interval, and the tip of connecting rod is fixed with the connection disc, and the connection disc is used for overlap joint clamping in valve wellhead department, and the outside of casing still is equipped with the box of placing that is used for installing gas detector.
Further, the middle part outside the casing is welded with the staple bolt, and the interval welding has the connecting rod on the staple bolt.
Further, a connecting frame is fixed on the inner side of the shell, and the connecting frame is fixed with the motor.
Further, a shaft sleeve is fixed on the output shaft, and a fan blade shaft is arranged on the shaft sleeve.
Compared with the prior art, the utility model has the following beneficial effects:
the utility model is suitable for the ventilation detection of the valve well, has simple manufacture and stable structure, and can greatly improve the safety and efficiency of the overhaul operation of the valve well. The connecting disc is used for clamping the ventilating device at the wellhead of the valve in a lap joint mode, so that the air replacement efficiency is high.
According to the utility model, the cube placement box of the gas detector is fixed on the outer side of the shell, soft rubber is placed in the cube placement box, and the cube placement box is used for placing the four-in-one gas detector, so that the gas composition in the valve well can be monitored and early-warned in real time.
The utility model has simple structure, can be specially used for ventilating the valve well, and has simple field installation and use and good ventilation effect.

Detailed Description
The utility model is further described below with reference to the drawings and the detailed description.
As shown in fig. 1-3, a ventilation device for a valve well comprises a shell 2, a connecting frame 3 is welded on the inner side of the shell 2, the connecting frame 3 is welded and fixed with a motor 7 or fixed through bolt fastening, a shaft sleeve 10 is fixed on an output shaft 9 of the motor 7, a fan blade shaft is fixedly installed on the shaft sleeve 10, fan blades 8 are installed on the fan blade shaft, net covers 1 are respectively installed at two ends of the shell 2 through bolt fastening, a hoop 4 is welded on the middle part of the outer side of the shell 2, connecting rods 5 are welded on the hoop 4 at intervals, connecting discs 6 are welded and fixed on the end parts of the connecting rods 5, the connecting discs 6 are used for being clamped at a valve well opening 12, a placing box 11 for installing a gas detector is welded on the outer side of the shell 2, and the placing box 11 is of a cube structure.
The valve well requiring personnel to enter for maintenance work has three main sizes of 600mm, 700mm and 800 mm. The structure of the utility model is matched with the size of the valve well, a connecting disc 6 of DN1000 is selected, and the connecting disc 6 is lapped on the valve well.
The device is vertically arranged opposite to the valve well, and when in use, the device can replace air in the valve well by switching on a power supply. When personnel in the well operate, if the gas detector alarms, personnel immediately withdraw from the valve well, and after the ventilation detection of the valve well is qualified, the personnel continue to operate, so that the safety of the operation of the valve well can be ensured.
