Abstract
The utility model provides an easily-opened piezometric tube opening protection device which is simple in structure and convenient in installation, so as to solve the problems that the prior piezometric tube opening protection device is difficult to open and is likely to be damaged. The easily-opened piezometric tube opening protection device comprises a tube cap, a tube core, a fastening device, an unlocking device and a magnet. By adopting the above technical scheme, the problems existing in the traditional piezometric tube opening protection device that time and labor are wasted, and the cost of the password lock-type protection device is high can be effectively solved. The piezometric tube opening protection device adopted by the utility model is simple in structure. The easily-opened piezometric tube opening protection device is fixed at the piezometric tube opening, the tube core is fixed by the fastening device, and then sealing protection on the tube opening is completed; when the device needs to be opened, the fastening device only needs to be drawn out and the tube core is attracted out by the magnet, the whole operation is simple, convenient and efficient; and the used tube core adopts plastic material, the replacement is convenient, and the whole cost is lower than that of the prior tube opening protection device.
Description
Technical field
The utility model relates to piezometric tube field, is specifically related to a kind of piezometric tube mouth of pipe simple in structure and easily drives protective device.
Background technology
Piezometric tube for measuring the relative pressure of liquid, be communicated in the open tube of fluid to be measured, can be used to monitor dam seepage line, osmotic pressure pressure, underground water table and around dam seepage flow etc.Piezometric tube mouth of pipe protective device is in the past totally enclosed type, during measurement, must coordinate and just can open pipe cap with two pipe wrenches, wastes time and energy.Accessed to your password afterwards and overlap lock mouth of pipe protective device, it can well protect the mouth of pipe, but single processing charges is very high; more than 10 times of former pipe cap; sometimes also there is easily mixed problem of stirring of password, then handy pipe wrench also, during measurement, pipe wrench still must be with instrument.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of piezometric tube mouth of pipe simple in structure, easy for installation easily to drive protective device, solves existing pressure measurement mouth of pipe protective device and opens trouble and hold flimsy problem.
The utility model solves the problems of the technologies described above by the following technical solutions:
A kind of piezometric tube mouth of pipe is easily driven protective device and is comprised of pipe cap, tube core, fastener, unlocking apparatus and magnet.
Described pipe cap is hollow right cylinder, on the inwall at pipe cap middle part, is provided with projection, is provided with the trapezoidal hole that penetrates sidewall in the upper portion side wall of pipe cap; Described tube core is right cylinder, and center is provided with iron prop; Described fastener one end is right cylinder, and the other end is leg-of-mutton cylinder, and described fastener is located in the trapezoidal hole on pipe cap sidewall, and pipe cap inside is led in right cylinder one end.
Described unlocking apparatus one end is and the corresponding triangle hole of fastener that the other end is horizontal handle.
Described unlocking apparatus and magnet are external device, are not connected with pipe cap body.
The utility model adopts technique scheme can effectively improve the higher problem of protection mouth of pipe cost of wasting time and energy of traditional mouth of pipe protective device existence and password lock, adopt the piezometric tube mouth of pipe protective device shown in the utility model simple to operate, the utility model is fixed on to piezometric tube mouth of pipe place, then will with fastener, tube core be fixed to the seal protection that completes line up, in the time of need to opening, only need exit fastener and tube core be washed out with magnet, but whole easy and simple to handle effective, tube core used adopts plastic material, change mouth of pipe protective device convenient and that overall cost is more existing much lower.

Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is cut-open view of the present utility model
Fig. 3 is the schematic diagram of locking device.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of piezometric tube mouth of pipe as described in Figure is easily driven protective device and is comprised of pipe cap 1, tube core 2, fastener 3, unlocking apparatus 4 and magnet 5.
Described pipe cap 1 is hollow right cylinder, on the inwall at pipe cap 1 middle part, is provided with projection, is provided with the trapezoidal hole that penetrates sidewall in the upper portion side wall of pipe cap 1; Described tube core 2 is right cylinder, and center is provided with iron prop; Described fastener 3 one end are right cylinder, and the other end is leg-of-mutton cylinder, and described fastener 3 is located in the trapezoidal hole on pipe cap 1 sidewall, and pipe cap 1 inside is led in right cylinder one end.
Described unlocking apparatus 4 one end are and the corresponding triangle hole of fastener 3 that the other end is horizontal handle.
Described unlocking apparatus 4 and magnet 5 are external device, are not connected with pipe cap 1 body.
During use, the latter half of pipe cap 1 of the present utility model is fixed on to the mouth of pipe place of piezometric tube, then the tube core 2 that iron prop is contained in inside is placed in pipe cap 1 the first half, and by unlocking apparatus 4, the fastener of side 3 is tightened and withstood tube core 2, and now tube core 2 is with regard to fixation; When needs are opened the mouth of pipe and carried out pressure measurement, unclamp fastener 3 with unlocking apparatus 4, and by magnet 5, tube core 2 sucking-offs can be carried out to pressure measurement.Whole system is simple in structure, simple operation, can greatly increase work efficiency.
