Abstract
The utility model discloses a novel double-layer sealing indicator for a pumping well, which comprises a main shell body and a sensing component. The indicator is characterized in that the main shell body is formed by one-time ejection molding, a battery box is arranged in a side cavity of the main shell body, and a battery cover is arranged outside the battery box and connected to the main shell body in a sealing way; an upper shell of a circuit board shell is arranged in another side cavity of the main shell, and a lower shell of the circuit board shell is connected to the upper shell of the circuit board shell in a sealing way, so as to form a sealing cavity which is internally provided with a circuit board; a main shell body sealing cover is arranged at the other side of the main shell body and is in sealing connection with the main shell body; and the sensing component is fixed on the main shell body sealing cover. In the utility model, the main shell body is formed by the plastic, so that the problem that metal materials shield and absorb wireless signals is effectively solved, the cost is saved, and the installation is more convenient; the structure of the battery box is enlarged, and the battery box is internally provided with four batteries, thereby improving the power supply performance of the indicator; and double-layer sealing is adopted between the circuit board and the lower shell of the main shell body, thereby achieving very good sealing, waterproof and moistureproof effects.
Description
The testing tool that technical field the utility model relates to oil oil pumping system duty is an indicator, relates in particular to a kind of novel double-layer sealing jack well power display instrument.
The oil well that background technology is recovered the oil with oil well pump in petroleum industry, the indicator of oil well has reflected the duty of oil-well pump of oil well.In oil recovery process, in time and exactly understand the duty of oil pumping system, to improving pumping efficiency, reduce cost for oil production and have very significant meaning with the raising oil well output.
The main casing of existing jack well power display instrument generally adopts metal material to process, and product is mutually rough and heavy, very inconvenience of assembling and installation; Wireless antenna relies on the main casing perforate to add the plastic seal structure and leans out, and wireless telecommunications energy major part is absorbed by the metal material of main casing self, and can't reach to have transmission range, and the main casing of metal also can cause shielding to a certain degree to wireless signal simultaneously; Sealed port is the face contact, and waterproof adopts the rubber cushion form, and waterproof effect depends on last assembler, when assembling is neat inadequately, is prone to cause and leaks, thereby often needing to cause refitting; The battery compartment that is provided with in the main casing adopts two batteries, and there is short circuit risk in the limited and battery lead easy abrasion of power supply capacity.
Summary of the invention is in order to overcome the deficiency of prior art, and the purpose of the utility model is to provide a kind of power supply capacity strong, good seal performance, can not shield and does not have the novel double-layer of letter signal sealing jack well power display instrument.
A kind of novel double-layer sealing of the utility model jack well power display instrument, it comprises main casing and inductive component, said main casing injection moulding one-shot forming, main casing is provided with battery compartment in the one side chamber, and battery compartment is provided with battery cover outward, and battery cover is sealedly connected on the main casing; The main casing opposite side is provided with the circuit board housing upper casing in the chamber, and the circuit board housing lower casing is sealedly connected on the circuit board housing upper casing, is provided with the seal chamber of circuit board in the formation; The main casing opposite side also is provided with the main casing gland bonnet and is tightly connected, and inductive component is fixed on the main casing gland bonnet.
Be provided with waterproof apron between said circuit board housing upper casing and the circuit board housing lower casing, be provided with waterproof apron between main casing opposite side and the main casing gland bonnet, be provided with waterproof apron between battery cover and the main casing.Adopt such structure, the indicator of the utility model is carried out double-layer seal, thereby reach good water-tight moisture effect.
Be provided with four batteries cavity volumes in the said battery compartment, cavity volume inner ring arc is corresponding with battery outer ring cylindricality.This design has strengthened the battery compartment structure, can place four batteries, improves the power supply capacity of indicator, and simultaneously, the cavity volume inner ring arc of battery compartment is corresponding with battery outer ring cylindricality, thereby can carry out spacingly well to battery, prevents that battery from wearing and tearing.
The utility model adopts the main casing of plastic shaping, efficiently solves the problem of metal material to the shielding and the absorption of wireless signal, practices thrift cost simultaneously, makes easier for installation; The utility model also strengthens the battery compartment structure, and four batteries are set in the battery compartment, improves the power supply capacity of indicator; Carry out double-layer seal between circuit board and main casing lower casing, thereby reach good water-tight moisture effect.
Hereinafter combines accompanying drawing and embodiment that the utility model is done further detailed explanation:
Fig. 1 is the utility model double-layer seal jack well power display instrument package assembly synoptic diagram.
Embodiment is as shown in Figure 1, and the utility model comprises main casing 1 and inductive component 2, said main casing 1 injection moulding one-shot forming, and main casing is provided with battery compartment 3 in the 1 one side chambeies, is provided with battery cover 4 outside the battery compartment 3, and battery cover 4 is sealedly connected on the main casing 1; Main casing is provided with circuit board housing upper casing 5 in the 1 opposite side chamber, and circuit board housing lower casing 5 is sealedly connected on the circuit board housing upper casing 6, is provided with the seal chamber of circuit board 7 in the formation; Main casing 1 opposite side also is provided with main casing gland bonnet 8 and is tightly connected, and inductive component 2 is fixed on the main casing gland bonnet 8.
Adopt the main casing 1 of plastic products, can practice thrift cost on the one hand, reduce product weight, easy for installation; On the other hand, main casing 1 adopts plastics to process, and can not shield and absorb the signal of wireless antenna, reaches due transmission range, makes the indicator measurement data more accurate.
Be provided with waterproof apron 9 between said circuit board housing upper casing 5 and the circuit board housing lower casing 6, be provided with waterproof apron 10 between main casing 1 opposite side and the main casing gland bonnet 8, be provided with waterproof apron 11 between battery cover 4 and the main casing 1.Adopt such structure, the indicator of the utility model is carried out double-layer seal, thereby reach good water-tight moisture effect.
3 are provided with four batteries cavity volumes in the said battery compartment, and cavity volume inner ring arc is corresponding with battery outer ring cylindricality.This design has strengthened battery compartment 3 structures, can place four batteries, improves the power supply capacity of indicator, and simultaneously, the cavity volume inner ring arc of battery compartment 3 is corresponding with battery outer ring cylindricality, thereby can carry out spacingly well to battery, prevents that battery from wearing and tearing.
