Utility model content
In view of this, the utility model aim is to provide a kind of coal mine pressure ventilation drilling pressure measuring unit, it is existing to solve There is pressure measurement pipeline present in technology to be filled by water and the problem of goaf air leaking.
Following technical solution that in order to achieve the above object, the utility model provides:
The utility model provides a kind of coal mine pressure ventilation drilling pressure measuring unit, including is used to be connected to goaf and workspace Lead test tube, described to lead test tube in the front end positioned at goaf side be water inlet, and the test tube of leading is positioned at workspace side End be communicated with U-shaped water seal, the free end of the U-shaped water seal is overflow port, and described lead connects in test tube away from itself and U-shaped water seal The place's of connecing certain distance is communicated with branch pipe, and the free end of the branch pipe is connected with U-shaped differential manometer by flexible hose.
Further, the goaf be top goaf above working face or it is adjacent with working face close on it is mined out Area.
Further, the water inlet is equipped with the stem bar in crown type or fork-shaped.
Further, the connection type of the stem bar and water inlet is welding, grafting or one kind in being screwed on.
Further, the water inlet sets the bullet shaped structure there are one inner hollow;The bullet shaped structure top And side wall is equipped with multiple through-holes, tail end is equipped with hollow threaded post.
Further, the bottom of the U-shaped water seal is equipped with sewage draining exit.
The utility model has the beneficial effects that:The utility model, which has, not to be had to discharge water, there is no leaking out, and pressure measurement Time is short, and pressure measurement is more accurate.
Other advantages, target and feature of the utility model will be explained in the following description to a certain extent It states, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or Person can be instructed from the practice of the utility model.The target of the utility model and other advantages can be said by following Bright book is realized and is obtained.
Description of the drawings
In order to keep the purpose of this utility model, technical solution and advantage clearer, below in conjunction with attached drawing to this practicality It is novel to be preferably described in detail, wherein:
Fig. 1 is the schematic diagram of the utility model coal mine pressure ventilation drilling pressure measuring unit;
Fig. 2 is the schematic diagram of the utility model bullet shaped structure.
Specific implementation mode
The utility model is further described With reference to embodiment.Wherein, being given for example only property of attached drawing Illustrate, expression is only schematic diagram rather than pictorial diagram, should not be understood as the limitation to this patent;In order to which this reality is better described With novel embodiment, the certain components of attached drawing have omission, zoom in or out, and do not represent the size of actual product;To ability For field technique personnel, the omitting of some known structures and their instructions in the attached drawings are understandable.
The same or similar label correspond to the same or similar components in the attached drawing of the utility model embodiment;In this practicality In novel description, it is to be understood that if having the instructions such as term "upper", "lower", "left", "right", "front", "rear" orientation or Position relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of describing the present invention and simplifying the description, It does not indicate or imply the indicated device or element must have a particular orientation, with specific azimuth configuration and operation, because The terms describing the positional relationship in the drawings are only for illustration for this, should not be understood as the limitation to this patent, for ability For the those of ordinary skill in domain, the concrete meaning of above-mentioned term can be understood as the case may be.
Referring to Fig. 1, the element numbers in attached drawing indicate respectively:The goafs 1-, the workspaces 2-, 3- lead test tube, 4-U type water Seal apparatus, 5- branch pipes, 6- flexible hoses, 7-U type differential manometers, 8- water inlets, 9- overflow ports, 10- stem bars, 11- bullet shaped structures Body, 12- through-holes, 13- threaded posts, 14- sewage draining exits.
Embodiment is substantially as shown in the picture:Coal mine pressure ventilation drilling pressure measuring unit provided in this embodiment, including be used for Test tube 3 is led in connection goaf 1 and workspace 2, and described to lead test tube 3 in the front end positioned at 1 side of goaf be water inlet 8, institute It states and leads test tube 3 and be communicated with U-shaped water seal 4 in the end positioned at 2 side of workspace, the free end of the U-shaped water seal 4 is overflow port 9, Described lead is being communicated with branch pipe 5 in test tube 3 away from itself and 4 junction certain distance of U-shaped water seal, and the free end of the branch pipe 5 passes through Flexible hose 6 is connected with U-shaped differential manometer 7;The goaf 1 be top goaf above working face or with working face phase Adjacent closes on goaf.
