Abstract
Description
Technical Field
[0001] This invention relates to the technical field of anti-theft for electric pump wells, and more particularly to an anti-theft junction box for electric pump wells. Background Technology
[0002] Currently, the existing standard electric pump well junction boxes are installed on the well site, and the cable is brought in from both sides with the cable exposed, giving thieves an opportunity to steal it. As a result, the surface cable of the electric pump well is often stolen, causing accidents and pump shutdowns.
[0003] Furthermore, theft of surface cables from electric pump wells often occurs at night because fewer workers are available for night patrols, and the inspection time is longer. Therefore, it often takes a considerable amount of time before workers discover the pump stoppage. By the time the oil production team retrieves the cable and reinstalls it during the day to restart production, it typically takes more than 15 hours. Generally, electric pump wells are high-yield wells, and cable theft and reinstallation result in significant production losses. Simultaneously, the sudden power outage due to cable loss causes substantial damage to the downhole units, with a high probability of unit burnout, and restarting the units requires significant costs. Therefore, to address these shortcomings, a theft-proof junction box for electric pump wells has been proposed. Summary of the Invention
[0004] The purpose of this invention is to provide an anti-theft junction box for electric pump wells, which overcomes the shortcomings of existing technologies, such as the lack of protection and warning devices for the surface cables of electric pump wells, which prevents night patrol workers from timely detecting the theft of surface cables, resulting in serious production losses in electric pump wells after cable theft, and the easy burning of the underground units.
[0005] To achieve the above objectives, the present invention provides an anti-theft junction box for electric pump wells, comprising: The enclosure is placed on the ground. Inside the enclosure, a current transformer and multiple terminals are installed. The current transformer is connected to a current indicator light via a connecting wire. A current indicator light is installed on the top of the enclosure. A transformer cable is inserted into the bottom of the enclosure. The transformer cable is connected to multiple terminals. After passing through multiple terminals, the transformer cable exits from the bottom of the enclosure and is connected to the electric pump well. The electric pump well uses a current indicator light to determine whether there is a fault or a power outage / pump stoppage. After power is supplied, the electric pump well operates normally. The current transformer in the housing senses the current, and the current indicator light stays on. If the current indicator light goes out, the electric pump well is malfunctioning or the pump stops due to power failure.

[0008] Preferably, a fixing seat is provided in the middle section of the housing, and multiple terminals are installed on the fixing seat. Each terminal has at least two fixing bolts at its top. The terminals are used to fix the transformer cable. The number of terminals is at least three, and the number of terminals is adapted to the number of the first inlet and the second inlet.

[0014] The present invention has the following beneficial effects: The anti-theft junction box for electric pump wells provided by this invention changes the transformer cable entry point from both sides to the bottom of the box, thus concealing the transformer cable entirely within the box. It is equipped with a current transformer and a current indicator light. After power is supplied, the current indicator light illuminates whenever current flows through the current transformer, providing timely feedback on the pump's operation. This reduces nighttime inspection time for workers, enabling timely detection of faults, facilitating nighttime management, preventing cable theft, and minimizing production disruptions and unit burnout accidents.

After passing through multiple terminals 3, the transformer cable exits from the bottom of the housing 2. The transformer cable is connected to the electric pump well. The electric pump well uses a current indicator light 1 to determine whether there is a fault or power outage and pump stoppage. After power is supplied, the electric pump well operates normally. The current transformer 4 in the housing 2 senses the current, and the current indicator light 1 stays on. If the current indicator light 1 goes out, the electric pump well is malfunctioning or the pump stops due to power failure.
[0019] In this anti-theft junction box, the box body 2 has a tetrahedral structure. The first door 8 is installed on one side of the box body 2, and the second door 7 is installed on the other side corresponding to the first door 8. Both the first door 8 and the second door 7 are anti-theft doors.
[0020] In practical applications, the bottom of the housing 2 is provided with multiple first cable inlets 5 and multiple second cable inlets 6.

[0022] In this anti-theft junction box, a fixing seat is provided in the middle of the box body 2. Multiple terminals 3 are installed on the fixing seat. Each terminal 3 has at least two fixing bolts at its top. The terminal 3 fixes the transformer cable through the fixing bolts. The number of terminals 3 is at least 3. The number of terminals 3 is adapted to the number of the first inlet port 5 and the second inlet port 6.
[0023] It should be noted that a current transformer 4 is installed at the center of one side of the bottom inside the enclosure 2. The interior of the current transformer 4 is the first inlet port 5. The distance between the current transformer 4 and the first door 8 of the enclosure is less than the distance between the current transformer 4 and the second door 8 of the enclosure.
[0024] In practical applications, the distance between the current indicator light 1 and the first door 8 of the enclosure is less than the distance between the current indicator light 1 and the second door 7 of the enclosure, and the night vision distance of the current indicator light 1 exceeds 200m.
[0025] In practical applications, the transformer cable is connected to the transformer, supplies power through the transformer, connects to the control panel, exits the control panel, enters the enclosure 2 through the first inlet 5, exits the enclosure 2 through the second inlet 6, and connects to the well pump of the electric pump well.
[0026] In this anti-theft junction box, the transformer cable is changed from entering from both sides to entering from the bottom of the box 2, so that the transformer cable is completely hidden inside the box 2. A current transformer 4 and a current indicator light 1 are installed. After power is supplied, as long as there is current passing through the current transformer 4, the current indicator light 1 will light up, and the current indicator light 1 can reflect the operation status of the well pump in a timely manner.
[0027] This invention provides an anti-theft junction box for electric pump wells, preventing cable theft, reducing production impact, and minimizing the risk of pump burnout. Simultaneously, indicator lights promptly reflect the pump's operating status, shortening nighttime inspection time for workers, enabling timely detection of faults, and facilitating nighttime management. The working principle of this anti-theft junction box for electric pump wells is described in detail below: In this embodiment, the box 2 is placed on the ground. The box 2 has a tetrahedral structure. The first door 8 is installed on the front side of the box 2, and the second door 7 is installed on the opposite side of the first door 8, that is, the second door 7 is installed on the rear side of the box 2. Both the first door 8 and the second door 7 are anti-theft doors. The current indicator light 1 is installed on the top of the box 2. The middle section inside the box 1 is provided with a fixing base. Three terminals 3 are installed on the fixing base. The spacing between adjacent terminals 3 is equal. Two fixing bolts are installed on each terminal 3. The current transformer 4 is installed in the middle of one side of the bottom inside the box 2. The terminal 3 is located in the middle in front of the current transformer 4. The first inlet 5 is located in the middle inside the current transformer 4. The second inlet 6 is located behind the first inlet 5. The first inlet 5 and the second inlet 6 are both located at the bottom of the box 2. The first door 8 is located in front of the first inlet 5, and the second door 7 is located behind the second inlet 6.
[0028] In practical applications, the current indicator light 1 is an LED brightness enhancement type, the color of the current indicator light 1 is red, and the night vision distance of the current indicator light 1 exceeds 200m.
[0029] In this embodiment, the transformer cable is connected to the control panel, passes through the control panel, enters the housing 2 through the first inlet 5, connects to three terminals 3, and is fixed by two fixing bolts on each terminal 3. After passing through the three terminals 3, the transformer cable exits the housing 2 through the second inlet 6 and is connected to the well pump of the electric pump well.
[0030] It should be noted that the bottom of the housing 2 has multiple first inlet ports 5 and multiple second inlet ports 6 on the front and rear sides respectively. The diameter of the first inlet port 5 is compatible with the diameter of the second inlet port 6. The diameters of the first inlet port 5 and the second inlet port 6 can both pass through the transformer cable. When there are 3 terminals 3, there are also 3 first inlet ports 5. Similarly, there are also 3 second inlet ports 6.
[0031] In this embodiment, the entire material of the box 2 is iron, the width of the box 2 is 50cm, the length of the box 2 is 50cm, the height of the box 2 is 70cm, the outer side of the box 2 is coated with an insulating layer, and the fixing base inside the box 2 is an iron plate.
[0032] In practical applications, the transformer cable entry method of enclosure 2 is changed from entering from both sides to entering from the bottom of enclosure 2, so that the transformer cable can be completely hidden inside enclosure 2. For the convenience of electricians, enclosure 2 is equipped with corresponding first door 8 and second door 7, and both doors are set as anti-theft doors. A current transformer 4 and a current indicator light 1 are installed on the top of enclosure 2. After the transformer is powered, the transformer cable transmits current and the electric pump well operates normally. The current of the transformer cable passes through the current transformer 4 in enclosure 2, and the current indicator light 1 will light up. If the current indicator light 1 goes out, it indicates that the electric pump well is malfunctioning or has stopped operating due to power failure. In practical applications, night patrol workers can identify the operating status of the electric pump well within a range of 200m. By observing the status of the current indicator light 1, night patrol workers can promptly detect whether the electric pump well is malfunctioning or has stopped operating due to power failure, effectively shortening the inspection time of night patrol workers.
[0033] The anti-theft junction box for electric pump wells provided by this invention changes the transformer cable entry point from both sides to the bottom of the box, thus concealing the transformer cable entirely within the box. It is equipped with a current transformer and a current indicator light. After power is supplied, the current indicator light illuminates whenever current flows through the current transformer, providing timely feedback on the pump's operation. This reduces nighttime inspection time for workers, enabling timely detection of faults, facilitating nighttime management, preventing cable theft, and minimizing production disruptions and unit burnout accidents.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
