Description

Technical Field

[0001] The utility model belongs to the technical field of instrument collectors, and in particular relates to a waterproof structure for an underground instrument collector. Background Art

[0002] At present, most instrument collectors on the market use mechanical seals, which rely on screws to tighten the shell and squeeze the sealing ring to achieve sealing effect;

[0003] The sealing effect of mechanical seals comes from the deformation of the sealing ring. The sealing ring is used underground for a long time and is prone to failure in harsh environments. The main board, valves and other modules cannot protect the cables and other parts by simply filling them with glue. When the instrument collector is working underground, since the collector is used in water or humid environments underground for a long time, the collector is prone to problems such as main board short circuit, signal transmission failure, and component damage. Therefore, a waterproof structure for underground instrument collectors is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a waterproof structure for a downhole instrument collector to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a waterproof structure for a downhole instrument collector, comprising an upper shell, a lower shell, a sealing ring, a glue inlet, an exhaust hole and a glue filling cavity, the upper shell comprising a first shell, a groove being provided at the bottom of the first shell, the lower shell comprising a second shell and a slot, the slot being provided on the upper surface of the second shell, the bottom of the first shell being inserted into the slot, the sealing ring being overlapped between the slot and the groove, the glue inlet and the exhaust hole being both provided on the upper surface of the second shell, and the glue filling cavity being provided between the first shell and the second shell.

[0006] By setting the above structure, when the first shell and the second shell are assembled together, the sealing ring located between the first shell and the second shell is deformed, and then sealant is injected into the periphery of the circuit board in the glue potting cavity through the glue inlet. When the sealant flows into several exhaust holes, the glue potting cavity is filled with sealant. The waterproof structure adopts a double sealing form of sealing ring and glue potting. The double sealing ensures the sealing effect of the waterproof structure. In a humid environment, even if the sealing ring fails due to long-term extrusion, the sealant can isolate the water vapor in the environment from important electronic components, so that the collector's circuit board is not prone to short circuit, signal transmission failure and component damage.

[0007] As a preferred solution, the upper surface of the second shell is connected to a circuit board, and the bottom of the second shell is connected to a battery compartment.

[0008] As a preferred solution, plugs are clamped in the glue inlet and the exhaust hole, and there are several exhaust holes.

[0009] As a preferred solution, the circuit board is arranged in the glue potting cavity.

[0010] As a preferred solution, the glue inlet and the plurality of exhaust holes are all connected to the glue pouring cavity.

[0011] As a preferred solution, the cross-sectional shape of the sealing ring is set to be circular, and the shapes of the sealing ring, the slot and the groove are all set to be annular.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model is provided with a sealing ring, a glue pouring cavity, a glue inlet and an exhaust hole. When the first shell and the second shell are assembled together, the sealing ring located between the first shell and the second shell is deformed, and then sealant is injected into the periphery of the circuit board in the glue pouring cavity through the glue inlet. When the sealant flows into a number of exhaust holes, the glue pouring cavity is filled with sealant. The waterproof structure adopts a double sealing form of a sealing ring and glue pouring. The double sealing ensures the sealing effect of the waterproof structure. In a humid environment, even if the sealing ring fails due to long-term extrusion, the sealant can isolate the water vapor in the environment from important electronic components, so that the circuit board of the collector is not prone to short circuit, signal transmission failure and component damage.

The upper shell 1 includes a first shell 101, and a groove 102 is provided at the bottom of the first shell 101. The lower shell 2 includes a second shell 201 and a slot 202. The slot 202 is provided on the upper surface of the second shell 201. The bottom of the first shell 101 is inserted into the slot 202. By providing the first shell 101 and the slot 202, when the first shell 101 is inserted into the slot 202, the portion of the first shell 101 inserted into the slot 202 can initially seal the gap between the first shell 101 and the second shell 201.

[0025] The sealing ring 3 is overlapped between the slot 202 and the groove 102. By providing the sealing ring 3, since the sealing ring 3 is arranged in the slot 202 and the groove 102, and when the first shell 101 and the second shell 201 are fixed together by screws, the sealing ring 3 is deformed. The deformed sealing ring 3 can enhance the sealing effect between the first shell 101 and the second shell 201;

[0026] The glue inlet 5 and the exhaust hole 6 are both provided on the upper surface of the second housing 201. By providing the exhaust hole 6, when the sealant is filled in the glue cavity 7, the gas in the glue cavity 7 can be discharged through the exhaust hole 6, so that the sealant can flow smoothly into the glue cavity 7 through the glue inlet 5 under the action of the glue filling equipment;

[0027] The glue inlet 5 and the exhaust hole 6 are both connected with plugs 9. By setting the glue inlet 5, sealant can be injected into the glue filling cavity 7 through the glue inlet 5.

[0028] There are a number of vent holes 6, and a plug 9 is provided to seal the glue inlet 5 and the vent holes 6;

[0029] The glue pouring cavity 7 is arranged between the first shell 101 and the second shell 201. The upper surface of the second shell 201 is connected to the circuit board 4, and the bottom of the second shell 201 is connected to the battery compartment 8. The circuit board 4 is arranged in the glue pouring cavity 7. The glue inlet 5 and several exhaust holes 6 are all connected to the glue pouring cavity 7. The cross-sectional shape of the sealing ring 3 is set to be circular, and the shapes of the sealing ring 3, the slot 202 and the groove 102 are all set to be annular.

[0030] The working principle and usage process of the present invention are as follows: when the structure needs to be assembled, the sealing ring 3 is placed in the slot 202, and then the first shell 101 is moved downward so that the bottom of the moving first shell 101 is inserted into the slot 202, and the groove 102 at the bottom of the first shell 101 contacts the sealing ring 3, and then the first shell 101 and the second shell 201 are connected together with screws, and then the first shell 101 and the second shell 201 are flipped 180 degrees so that the first shell 101 is located below the second shell 201, and then multiple plugs 9 are respectively removed from the glue inlet 5 and the multiple exhaust holes 6, and then a glue filling device is used to inject sealant into the glue filling cavity 7 through the glue inlet 5, and the sealant flows into the space around the glue filling cavity 7, and then the gas in the glue filling cavity 7 is discharged through the multiple exhaust holes 6. When the sealant flows out of the multiple exhaust holes 6, then multiple plugs 9 are respectively inserted into the glue inlet 5 and the multiple exhaust holes 6, and then the battery compartment 8 is connected to the bottom of the second shell 201 by multiple screws.
