When the needle is located in the qualified pressure value interval, the annular qualified indicator light belt lights up; when the needle is located in the unqualified pressure value interval, the annular unqualified indicator light belt lights up. Even in dim light conditions, the staff can quickly distinguish whether the pressure of the pipeline is qualified. It is more intuitive in the mine and more convenient to use.

[0005] In order to solve the above technical problems, the technical solution of the utility model is implemented as follows:

[0006] A mine water supply pipeline pressure monitoring device comprises a pressure measuring valve body, a dial is fixed on the top of the pressure measuring valve body, a pressure transmission assembly extending into the dial is installed in the pressure measuring valve body, and a needle connected to the pressure transmission assembly is installed at the center of the dial;

[0014] Among them, the annular qualified indicator light belt is green when it is lit; the annular unqualified indicator light belt is red when it is lit.

[0015] Using the above scheme, when the annular qualified indicator light is green, it means that the pressure value is qualified at this time, that is, the pressure value is between 0.3-0.5MPa; when the annular unqualified indicator light is red, it means that the pressure value is unqualified at this time, that is, the pressure value is below 0.3MPa and above 0.5MPa, and it should be adjusted in time.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figure 1 to Figure 2 , Figure 5 to Figure 6As shown, a pressure monitoring device for a mine water supply pipeline comprises a pressure measuring valve body 1, a dial 2 is fixed on the top of the pressure measuring valve body 1, a pressure transmission assembly 3 extending into the dial 2 is installed in the pressure measuring valve body 1, and a needle 4 connected to the pressure transmission assembly 3 is installed at the center of the dial 2;

[0033] An annular qualified indicator light belt 5 and an annular unqualified indicator light belt 6 are respectively fixed to the edge of the dial 2, and the annular qualified indicator light belt 5 and the annular unqualified indicator light belt 6 are connected to form a complete annular indicator light belt, and the annular qualified indicator light belt 5 and the annular unqualified indicator light belt 6 emit different colors;

[0034] The annular qualified indicator light band 5 corresponds to the qualified pressure value interval of the dial 2, and the annular unqualified indicator light band 6 corresponds to the unqualified pressure value interval of the dial 2;

[0035] The end of the needle 4 can swing back and forth in the annular qualified indicator light strip 5 and the annular unqualified indicator light strip 6; when the end of the needle 4 enters the annular qualified indicator light strip 5, the switch of the annular qualified indicator light strip 5 is in a closed loop, and then the annular qualified indicator light strip 5 lights up; when the end of the needle 4 enters the annular unqualified indicator light strip 6, the switch of the annular unqualified indicator light strip 6 is in a closed loop, and then the annular unqualified indicator light strip 6 lights up.

[0036] The device installs the annular qualified indicator light strip 5 corresponding to the qualified pressure value interval of the dial 2, and installs the annular unqualified indicator light strip 6 corresponding to the unqualified pressure value interval of the dial 2. When the needle 4 is located in the qualified pressure value interval, the annular qualified indicator light strip 5 lights up; when the needle 4 is located in the unqualified pressure value interval, the annular unqualified indicator light strip 6 lights up. Even in dim light conditions, the staff can quickly distinguish whether the pressure of the pipeline is qualified. It is more intuitive in the mine and more convenient to use.

[0037] like Figures 5 to 7 As shown, two annular guide pieces 7 electrically connected to the switches thereof are installed on the inner side of the annular qualified indicator light strip 5, and the two annular guide pieces 1 7 are spaced apart; two annular guide pieces 2 8 electrically connected to the switches thereof are installed on the inner side of the annular unqualified indicator light strip 6, and the two annular guide pieces 2 8 are spaced apart; a guide core 9 located between the two annular guide pieces 1 7 or between the two annular guide pieces 2 8 is fixed to the end of the pointer 4, and the two ends of the guide core 9 are in contact with the two annular guide pieces 1 7 or the two annular guide pieces 2 8 respectively.

[0038] In order to realize automatic triggering of the annular qualified indicator light strip 5 and the annular unqualified indicator light strip 6, when the guide core 9 of the needle 4 enters between the two annular guide pieces 1 7, the annular qualified indicator light strip 5 lights up; when the guide core 9 of the needle 4 enters between the two annular guide pieces 2 8, the annular unqualified indicator light strip 6 lights up.

[0039] like Figure 1 to Figure 2 As shown, the surface circumferential array of the dial 2 has pressure scale lines; for example, the qualified pressure value interval on the pressure scale line is set to 0.3-0.5MPa; the unqualified pressure value interval on the pressure scale line is set to below 0.3MPa and above 0.5MPa;

[0040] The annular qualified indicator light strip 5 is green when it is lit, and the annular unqualified indicator light strip 6 is red when it is lit.

[0041] When the annular qualified indicator light belt 5 lights up green, it means that the pressure value is qualified at this time, that is, the pressure value is between 0.3-0.5MPa; when the annular unqualified indicator light belt 6 lights up red, it means that the pressure value is unqualified at this time, that is, the pressure value is below 0.3MPa and above 0.5MPa, and it should be adjusted in time.

[0042] like Figure 3 to Figure 4 As shown, the pressure transmission assembly 3 includes a transmission guide rod 301, a propulsion chamber 10 and a reset chamber 11 are provided in the pressure measuring valve body 1, and the transmission guide rod 301 passes through the propulsion chamber 10 and the reset chamber 11 in sequence and then extends into the dial 2; a push plate 302 fixed to the end of the transmission guide rod 301 is installed in the propulsion chamber 10; the diameter of the push plate 302 is larger than the diameter of the transmission guide rod 301; a reset push plate 303 fixed to the rod body of the transmission guide rod 301 is installed in the reset chamber 11, and the reset push plate 303 is fixed to the rod body of the transmission guide rod 301. The push plate 303 is slidably connected to a guide shaft 304 fixed in the reset chamber 11, and a reset spring 305 is mounted on the guide shaft 304 to push the reset chamber 11 toward the propulsion chamber 10; a rack 306 fixed on the rod body of the transmission guide rod 301 is installed in the dial 2, and a gear 307 meshing with the rack 306 is also rotatably connected in the dial 2, and the pointer 4 is concentrically connected to the gear 307; a sealing sleeve 12 is also fixed between the propulsion chamber 10 and the reset chamber 11.

[0043] In order to realize the transmission of pressure, the pressure in the water pipe contacts the transmission guide rod 301 through the push plate 302. At this time, the reset spring 305 is compressed, thereby pushing the rack 306 to move. Under the meshing transmission of the teeth, the gear 307 is rotated, and finally the hand 4 is flipped, and the water pressure is indicated by the hand 4.

[0044] The working principle of this utility model:

[0045] When in use, the flange on the pressure measuring valve body 1 is butted against the water pipe in the mine. At this time, the pressure measuring valve body 1 is in communication with the water pipe, and is used to monitor the water pressure in the water pipe.

[0046] During monitoring, 0.3-0.5MPa is set as the qualified interval of water pressure value. When the needle 4 indicates the qualified interval of water pressure value, the guide core 9 of the needle 4 enters between the two annular guide pieces 7, and the annular qualified indicator light 5 lights up green. Figure 2 When the needle 4 indicates the unqualified interval of the water pressure value, the guide core 9 of the needle 4 enters between the two annular guide pieces 8, the annular unqualified indicator light 6 lights up red, such as Figure 1 as shown.

[0047] In summary, since it is dark inside the mine, the staff only needs to distinguish whether the light is green or red to quickly determine whether the pressure of the pipeline is qualified. It is more intuitive in the mine and more convenient to use.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
