[0035] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] In order to avoid accidents such as motor overload, phase loss, dry pumping, etc. in the oil pump, the starting and operating current of the oil pump needs to be measured regularly. In the relevant technology, the three-phase power lines in each oil pump are very close in the wire slot. The staff is required to pull the power lines for each measurement, so it is easy for the power connection to loosen, causing the oil pump motor to heat up; or, the staff may cause the power lines to fall off if they use too much force, resulting in electric shock.

[0037] Regarding the above situation, first of all, please refer to Figure 1-Figure 3 The present application proposes an oil pump device 1, comprising a main body 10, a stopper 20 and a power line 30. A motor is arranged in the main body 10, and the power line 30 is electrically connected to the motor to provide a working voltage for the motor.

[0038] The main body 10 has a wire groove 11 having a first opening 12 ; the stopper 20 is slidably connected to the bottom wall 111 of the wire groove 11 ; and the power cord 30 is installed in the wire groove 11 .

[0039] Specifically, the first opening 12 is used for external objects to enter the wire groove 11. The first opening 12 is arranged opposite to the bottom wall 111 of the wire groove 11. The embodiment of the present application does not specifically limit the shape of the main body 10 and the wire groove 11. For example, the main body 10 is a cylinder, and the wire groove 11 can be annular and arranged on the peripheral side wall of the main body 10; or, the main body 10 is a cube, and the wire groove 11 can be arranged in a long strip on the outer side wall of the main body 10. There are multiple power lines 30 in this embodiment. For example, the oil pump device 1 can adopt a three-phase three-wire system, a three-phase four-wire system, or a three-phase five-wire system.

[0040] The limiting member 20 has a first position and a second position. Figure 4 As shown, when the stopper 20 slides to the first position, the stopper 20 is close to the first opening 12, and when the power cord 30 is located in the wire slot 11, the stopper 20 contacts the power cord 30 facing the side of the first opening 12 to provide support for the power cord 30. Figure 5As shown, when the limit member 20 slides to the second position, the limit member 20 is away from the first opening 12, and when the power cord 30 is located in the wire groove 11, the limit member 20 is spaced apart from the power cord 30 on the side facing the first opening 12, that is, there is a first gap 22 between the limit member 20 and the power cord 30. When it is necessary to detect the current on the power cord 30 in the oil pump device 1, the current of the power cord 30 can be detected at the first gap 22.

[0041] It should be noted that, in the embodiment of the present application, a slidable limit member 20 is provided in the wire groove 11. On the one hand, the limit member 20 can provide support for the power cord 30 in the wire groove 11. On the other hand, the limit member 20 can provide space for current detection of the power cord 30, so that the detection tool can detect the power cord 30 from the first gap 22, thereby reducing the pulling of the power cord 30 by the oil pump device 1 when performing current detection, thereby reducing the possibility of the power cord 30 in the oil pump device 1 loosening.

[0042] In some embodiments, taking the main body 10 as a cylinder as an example, the limit member 20 can be slidably connected to the bottom wall 111 of the wire groove 11 along a direction perpendicular to the axial direction of the main body 10, or the limit member 20 can also be slidably connected to the bottom wall 111 of the wire groove 11 along the axial direction of the main body 10. When the limit member 20 is in the first position, the power cord 30 contacts the limit member 20, and when the limit member 20 is in the second position, the power cord 30 and the limit member 20 are spaced apart.

[0043] It should also be noted that the oil pump device 1 also includes a pressing piece, which can be arranged on the outer side of the main body 10. The pressing piece is linked to the limiting piece 20 and is used for the user to press. When external force acts on the pressing piece, the pressing piece applies a force to the limiting piece 20 to cause the limiting piece 20 to slide and change its position.

[0044] See also Figure 2-Figure 3 In some embodiments of the present application, a first groove 13 is formed on the bottom wall 111 of the wire groove 11, and a limiting member 20 is located in the first groove 13. The limiting member 20 is slidably connected to the bottom wall 111 of the wire groove 11 along a first direction L1, and the first direction L1 is perpendicular to the bottom surface of the first groove 13, wherein the first groove 13 provides an installation base and a limiting function for the limiting member 20, thereby reducing displacement of the limiting member 20 during sliding.

[0045] The limiting member 20 has a first side surface 21. Figure 4 As shown, in the first position, the first side surface 21 is flush with the bottom wall 111 of the wire trough 11, which is conducive to the first side surface 21 and the bottom wall 111 of the wire trough 11 jointly providing support for the installation of the power cord 30; Figure 5As shown, in the second position, the first side surface 21 and the bottom wall 111 of the wire trough 11 are spaced apart along the first direction L1, and the limit member 20 contacts the bottom surface of the first groove 13. At this time, the bottom wall 111 of the wire trough 11 can continue to provide support for the power cord 30. There is a first gap 22 between the first side surface 21 and the bottom wall 111 of the wire trough 11. The first gap 22 can provide a detection space for current detection of the power cord 30, and there is no need to pull out the power cord 30 during current detection.

[0046] See also Figure 6-Figure 7 In some embodiments of the present application, a plurality of first accommodating grooves 112 arranged along the second direction L2 are provided on the bottom wall 111 of the wire trough 11, each first accommodating groove 112 is used to accommodate a power cord 30, and the second direction L2 is perpendicular to the extension direction of the wire trough 11.

[0047] Specifically, the first receiving groove 112 can provide an installation base for the power cord 30, and each first receiving groove 112 can accommodate a power cord 30 to prevent the power cord 30 from shifting in the wire groove 11. Exemplarily, the main body 10 is a cylinder, and the wire groove 11 is arranged in a ring on the peripheral side wall of the main body 10. At this time, the second direction L2 is parallel to the axial direction of the main body 10. A plurality of first receiving grooves 112 can be arranged in sequence along the axial direction of the main body 10, which is conducive to saving the space of the wire groove 11. Alternatively, a plurality of first receiving grooves 112 can also be arranged at intervals along the axial direction of the main body 10 to increase the spacing between adjacent power cords 30, which is conducive to the subsequent current detection operation of the power cord 30. Among them, this embodiment does not specifically limit the number of power cords 30. For example, the power cords 30 have 3, 4, 5, etc., and the number of first receiving grooves 112 corresponds to the number of power cords 30.

[0048] For further information, please see Figure 6-Figure 7 In some embodiments of the present application, the limiting member 20 has a first side surface 21 facing the first opening 12, and a plurality of second accommodating grooves 211 arranged along the second direction L2 are provided on the first side surface 21, each second accommodating groove 211 is used to accommodate a power cord 30, and the second accommodating grooves 211 are connected to the first accommodating grooves 112 in a one-to-one manner, so that the power cord 30 can be arranged in sequence in the wire groove 11 according to the extension direction of the first accommodating groove 112 and the second accommodating groove 211, thereby reducing the possibility of the power cord 30 loosening and shifting.

[0049] In some embodiments of the present application, the oil pump device 1 also includes a fixing member (not shown in the figure) connected to the main body 10, and the fixing member is arranged at the first opening 12 of the wire groove 11. The fixing member can press the power cord 30 in the wire groove 11 to fix the power cord 30, thereby preventing the power cord 30 from being displaced or loosened in the wire groove 11.

[0050] Specifically, the fixing member and the main body 10 can be slidably connected, rotatably connected or detachably connected. When the power cord 30 is installed, the fixing member can move relative to the main body 10 so that the power cord 30 can smoothly enter the wire groove 11, and then the fixing member is pressed onto the power cord 30 to complete the installation and fixation of the power cord 30.

[0051] In some embodiments of the present application, a plurality of fixing members are provided, and the plurality of fixing members are arranged at intervals along the extension direction of the wire groove 11 , thereby strengthening the fixation of the power cord 30 and further preventing the power cord 30 from being displaced or loosened in the wire groove 11 .

[0052] See also Figure 7 In some embodiments of the present application, the main body 10 includes a shell 41 and a cover plate 42 , the wire groove 11 is opened in the shell 41 , the cover plate 42 is movably connected to the shell 41 , and the cover plate 42 covers the first opening 12 .

[0053] Specifically, the cover 42 and the shell 41 can be slidably connected, rotatably connected or detachably connected. When the power cord 30 needs to be installed, repaired or tested, the cover 42 can be opened to expose the first opening 12 so that the staff can perform relevant operations on the power cord 30 in the wire trough 11. The setting of the cover 42 can also protect the power cord 30 in the wire trough 11.

[0054] In a second aspect, an embodiment of the present application further provides an oil pump measurement system, comprising a clamp ammeter (not shown in the figure) and an oil pump device 1 as described in any of the above embodiments, wherein the clamp ammeter is detachably arranged on the main body 10.

[0055] Specifically, the clamp ammeter is used to detect the operating current of the power cord 30 in the oil pump device 1. The clamp ammeter is detachably connected to the main body 10, which is convenient for storage of the clamp ammeter and convenient for users to use at any time to detect the current of the power cord 30.

[0056] The clamp ammeter includes a Roche sensing coil. When the current of the power cord 30 needs to be detected, the limiter 20 can be slid first, so that the limiter 20 slides from the first position to the second position, and then the Roche sensing coil is inserted into the first gap 22 from the first opening 12, and then passed out of the first opening 12 from the first gap 22, so that the power cord 30 is located between the Roche sensing coils, so that the current on the power cord 30 can be detected without pulling the power cord 30. The specific working principle of the clamp ammeter has been disclosed in the relevant technology, and will not be repeated here.

[0057] In some embodiments of the present application, the main body 10 further has a storage slot (not shown in the figure), which is independently provided with the wire slot 11, and the clamp ammeter is located in the storage slot. Specifically, the storage slot provides an installation space for the clamp ammeter, and the clamp ammeter can be taken out of the storage slot when in use and put back into the storage slot after use.

[0058] Furthermore, in some embodiments of the present application, the oil pump measurement system also includes a connecting rope (not shown in the figure), and the clamp ammeter is connected to the wall of the storage slot through the connecting rope. The provision of the connecting rope is conducive to the placement of the clamp ammeter, avoiding the user from placing it casually after use.
