Description

Fire plug

Technical field

The present invention relates to a kind of fire-fighting equipment field, be specifically related to a kind of fire plug.

Background technology

Conventional fire plug generally can be used for fire extinguishing or for irrigating greenbelt, no matter be in fire extinguishing or in the time irrigating, it is upper and lower that hydraulic pressure in fire plug must remain on a preset value, cause in the too little meeting of when fire extinguishing hydraulic pressure that the jet length of hydraulic giant is too short does not reach requirement remote or high-altitude fire extinguishing, when irrigation, can run into equally such problem, but the hydraulic pressure in fire plug is determined by the pressure of supply water of the side of water supply, is in case of emergency difficult to solve the problem of pressure of supply water.

Summary of the invention

Goal of the invention: the invention provides a kind of fire plug, can realize and measure at any time self hydraulic pressure, user can also be in hydraulic pressure deficiency manual adjustments hydraulic pressure to alleviate the deficiency of hydraulic pressure.

Technical scheme: fire plug of the present invention, comprise key, delivery port and water inlet, key inside between delivery port and water inlet arranges one for controlling the spherical piston of water outlet bore, the diameter of this spherical piston is less than key internal diameter and is greater than key external diameter, and the through-hole aperture of this spherical piston equals key internal diameter; In the outside position relative with spherical piston of key, one rotary handle is set, this rotary handle is for passing through closure and the unlatching of a swing arm control spherical piston, and one end of this swing arm is fixed on rotary handle, and the other end is fixed on spherical piston outer wall; On described spherical piston inwall, be also provided with hydrostatic sensor, the pressure meter for showing the hydraulic pressure numerical value that this hydrostatic sensor measures is installed in the middle part of rotary handle, and hydrostatic sensor transmits through the first data wire the hydraulic pressure numerical value measuring be shown on pressure meter.

In order to meet the home-confined hydraulic pressure that just can monitor each fire plug inside, a certain area of client, on the key of the fire plug in the present invention, be also provided with data long-distance transmissions equipment.

Data long-distance transmissions equipment is wirelessly transmitted to background server by GPRS by the data signal of hydraulic pressure.

Operating principle: the fire plug in the present invention is in the time of work, when spray from water outlet and the distance of water when inadequate, can rotate rotary handle, rotary handle drives swing arm, and then drive spherical piston slowly the bore of delivery port to be dwindled, and in the situation that discharge is identical, the water velocity of dwindling nature and can increase water outlet of water outlet aperture, also just indirectly increase the hydraulic pressure of water outlet, thereby alleviated to a certain extent the defect of hydraulic pressure deficiency; The pressure meter that hydrostatic sensor on spherical piston inwall is transferred to by data wire the hydraulic pressure numerical value measuring on rotary handle is shown to user.

Beneficial effect: the present invention can measure static state and dynamic water-pressure in fire plug on the one hand, can also regulate on the other hand the hydraulic pressure of water outlet of fire hydrant, to alleviate the deficiency of delivery port hydraulic pressure.

Brief description of the drawings

Fig. 1 is structural representation of the present invention;

Fig. 2 be data long-distance transmissions equipment by the hydraulic pressure transfer of data recording the schematic diagram to client.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is further described.

The first embodiment, as shown in Figure 1, the fire plug in present embodiment comprises key 1, delivery port 2 and water inlet 3, and water inlet 3 is communicated with water supply side, and delivery port 2 is for water receiving pipe; Key 1 inside between delivery port 2 and water inlet 3 is provided with a spherical piston 4, in the middle of this piston 4, there is a through hole, the diameter of through hole is identical with the internal diameter of key 1, the diameter of spherical piston 4 be greater than key 1 internal diameter, be less than the external diameter of key 1, for the ease of closure and the unlatching of spherical piston 4, one swing arm 6 is set need to spherical piston 4, one end of this swing arm 6 is fixed on the outer wall of spherical piston 4, the other end is connected with rotary handle 5 through key 1, and rotary handle 5 is for controlling closure and the unlatching of spherical piston 4 by swing arm 6; In the present embodiment, on the inwall of spherical piston 4, be also provided with the hydrostatic sensor 7 for measuring fire plug inside water pressure, learn that for the ease of user fire plug inside water pressure also arranges a pressure meter 8 on rotary handle or on key, the hydraulic pressure numerical value that hydrostatic sensor 7 measures can be transmitted and is shown on pressure meter 8 by the first data wire 9 and obtain for user.

Fire plug is under idle state, hydrostatic sensor 7 is also always in running order, the hydraulic pressure that just now hydrostatic sensor 7 measures is the static hydraulic pressure in fire plug, measure static hydraulic pressure and static hydraulic pressure numerical value is shown in to the hydraulic pressure of being convenient to user on pressure meter 8 and understanding at any time fire plug inside by the first data wire 9, to adjust in time hydraulic pressure in the time that hydraulic pressure is not enough, prevents trouble before it happens; Fire plug in working order under, the hydraulic pressure that hydrostatic sensor 7 measures is the dynamic water-pressure between fire plug water inlet 3 and delivery port 2, in the time that the hydraulic pressure numerical value showing on pressure meter 8 is less than preset value, user can regulate the unlatching of spherical piston 4 with closed by rotating rotary handle 5, in the time that the through hole of spherical piston 4 is completely parallel with key 1, spherical piston 4 is opened completely, is now the position of spherical piston under normal circumstances; Closed spherical piston 4 slowly in the time that user rotates rotary handle 5, in the process of closed spherical piston 4 slowly, water outlet bore dwindles gradually, at water inlet 3 inflows constant in the situation that, the flow velocity that the dwindling of water outlet bore will certainly increase delivery port 2 place's current increases, and then indirectly increased the hydraulic pressure at delivery port 2 places, alleviate to a certain extent the deficiency of fire plug inside water pressure.

The second embodiment, as shown in Figure 1, is also provided with hydraulic pressure numerical value long-distance transmissions for hydrostatic sensor 7 the is measured data long-distance transmissions equipment 10 to client on fire plug key 1 outer wall in present embodiment.Be illustrated in figure 2 data long-distance transmissions equipment 10 by the hydraulic pressure transfer of data recording the schematic diagram to client, hydrostatic sensor, single-chip microcomputer and GPRS module are powered by power subsystem, hydrostatic sensor 7 is recording after hydraulic pressure, the analog circuit signal that hydraulic signal can be converted to, and this analog electrical signal is transferred to the single-chip microcomputer of data long-distance transmissions equipment 10 by the second data wire 11, single-chip microcomputer is encoded and stores memory cell into above-mentioned analog electrical signal, data long-distance transmissions equipment 10 is just by GPRS (general packet radio service) (General Packet Radio Service afterwards, GPRS) data signal of above-mentioned hydraulic pressure being sent to background server checks for user, so just make user to stay indoors and just can understand the hydraulic pressure situation that is distributed in each fire plug inside in LAN, be convenient in time the hydraulic pressure of fire plug inside be adjusted, to prevent that in case of emergency the deficiency due to hydraulic pressure causes the loss that cannot retrieve.

Persons of ordinary skill in the art may appreciate that the respective embodiments described above are to realize specific embodiments of the invention, and in actual applications, can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
