Abstract
The utility model relates to a lever type coal bunker reserve condition detecting mechanism which comprises a stress rod provided with an arc-shaped surface, a coal bunker, a lever, a detecting rod, a lever type fan gear and a pointer, wherein the middle of the lever is connected with the outer wall of the coal bunker in a rotary mode, the detecting rod is arranged at one end of the lever, balancing springs are arranged at the two ends of the detecting rod respectively, the stress rod is arranged at the other end of the lever, the end, provided with the arc-shaped surface, of the stress rod is placed inside the coal bunker, and a force measurement spring is arranged between the stress rod and the coal bunker; one end of the lever type fan gear is connected with the middle of the detecting rod, a pointer gear is arranged at the other end of the lever type fan gear, and the pointer is arranged on the pointer gear. The lever type coal bunker reserve condition detecting mechanism has the advantage that the problems existing in the prior art that resource waste is caused by unknown reserve information of the coal bunker and the reduction of coal quality and the existence of potential dangers are caused by long-time reserving of raw coal are solved.
Description
Technical field
The utility model relates to coal bunker storage facilities, relates in particular to a kind of coal bunker and stores situation lever testing agency.
Background technology
Existing bucket type coal bunker normal open inflow-rate of water turbine monitoring and statistics is calculated and judgement storage capacity, the long limit of raw coal is along with higher moisture, and the coal temperature of long-time storage warehouse bottom raises gradually, thereby has the danger that causes spontaneous combustion, in the severe especially situation of condition, obtain constantly current coal amount, the method is difficult to be utilized.
Present a kind of lever testing agency, by the number of coal bunker coal amount storage capacity, thereby band arc force rod is produced to pressure, dynamometer spring has larger ergometry, only have coal amount to reach certain, the size of pressure is enough to cause that thereby dynamometer spring distortion causes the rotation of lever, balance measuring staff is because thereby the rotation of effort lever is moved to the left, again by lever elevating arc driving pinion and the pointer that is coaxially connected thereof, and finally on index dial, reflect, the idle running in transmission is eliminated in the effect of hairspring.This invention realizes the detection of coal bunker coal amount, thereby can judge whether current coal bunker is fully utilized, and current coal has been stored the data message that how long provides important.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of coal bunker and stores situation lever testing agency, solves the deficiencies in the prior art.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of coal bunker stores situation lever testing agency, comprises force rod, coal bunker, lever, measuring staff, lever elevating arc, pointer with arcwall face; The middle part of described lever and the outer wall of described coal bunker are rotationally connected; Described measuring staff is arranged at one end of described lever, and the two ends of described measuring staff are respectively equipped with balancing spring; Described force rod is arranged at the other end of described lever, and one end of the arcwall face of described force rod is arranged at the inside of described coal bunker, between described force rod and described coal bunker, is provided with dynamometer spring; One end of described lever elevating arc is connected with the middle part of described measuring staff, and the other end of described lever elevating arc is provided with pointer gear, and described pointer is arranged on described pointer gear.
The beneficial effects of the utility model are: solved existing because failing to understand the wasting of resources causing without coal bunker reserve information and storing and cause coal Quality Down and potential dangerous problem because raw coal is long-time.The principle of utilizing effort lever stress to rotate, has solved the coaling problem of situation detection difficult of under mal-condition large-scale coal store; Adopt lever elevating arc driving pinion and rotate with its pointer being coaxially connected, making the moving displacement of measuring staff that corresponding value is shown on index dial, thereby realized according to the storage capacity of numerical value judgement coal.And the length of inferring the storage time of producing coal according to the variation of reserves.
Further: described pointer gear is provided with hairspring, described hairspring is that resilient material is made; One end of described hairspring is fixedly connected with the center of described pointer gear, and the other end of described hairspring is fixedly connected with described coal bunker.
The beneficial effect of above-mentioned further scheme is: hairspring can be eliminated the idle running of lever elevating arc and pointer gear transmission.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of coal bunker stores situation lever testing agency, comprise force rod 1 (the arcuate structure increase lifting surface area with arcwall face, make to be subject to along bar, to point to joint efforts, be conducive to be with bow to press to flexibly lever 4 in certain effect power situation, and it rotated), coal bunker 3, lever 4, measuring staff 6, lever elevating arc 7, pointer 8; The outer wall of the middle part of described lever 4 and described coal bunker 3 is rotationally connected; Described measuring staff 6 is arranged at one end of described lever 4, and the two ends of described measuring staff 6 are respectively equipped with balancing spring 5 (two balancing springs 5 guarantee that measuring staff 6 is in normal working position, also can change the adjusting that two balancing springs 5 reach structural sensitivity); Described force rod 1 is arranged at the other end of described lever 4, and one end of the arcwall face of described force rod 1 is arranged at the inside of described coal bunker 3, between described force rod 1 and described coal bunker 3, be provided with dynamometer spring 2 (dynamometer spring 2 is for there being the stiffness spring of certain and pressure, make structure more safe and reliable); One end of described lever elevating arc 7 is connected with the middle part of described measuring staff 6, and the other end of described lever elevating arc 7 is provided with pointer gear 10, and described pointer 8 is arranged on described pointer gear 10.
By the change in displacement of measuring staff 6, be converted into the rotation of lever elevating arc 7, thereby drive pointer gear 10 and rotate with its pointer being coaxially connected 8, it is illustrated on index dial to corresponding numerical value.
Described pointer gear 10 is provided with hairspring 9, and described hairspring 9 is made for resilient material; One end of described hairspring 9 is fixedly connected with described pointer gear 10 center, and the other end of described hairspring 9 is fixedly connected with described coal bunker 3.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
