Description

Technical Field

[0001] The utility model belongs to the technical field of oil pump detection equipment, in particular to an oil pump leakage detection device. Background Art

[0002] The oil pump is a light and compact pump, which can be divided into three categories: in-line, distributed and single-body. In order to ensure that the oil pump does not affect normal use due to leakage, the air tightness of the oil pump is often tested during production or maintenance.

[0003] The current air tightness test device generally fixes the oil pump in a test box first, then adds water to the test box, and then passes high-pressure gas into the oil pump through the air intake pipe, and observes whether bubbles are generated below the liquid surface to determine whether the oil pump is airtight. However, ordinary test boxes cannot position and clamp the oil pump, making it difficult to position the oil pump in the center, and it may shift, affecting the test process and results.

[0004] The utility model patent with application number CN202220901998.2 discloses an oil pump air tightness detection device, which places the oil pump on a storage plate and fixes the position of the oil pump through a contact plate so that the oil pump is placed in the center. However, the patent does not take into account the weight of the oil pump itself. The oil pump is large and heavy, and the detection box has a certain depth. Each time before placing the oil pump, the oil pump needs to be lifted to above the height of the box, moved into the box and then put down. After the test, it is necessary to repeat the operation to move the oil pump away, which is very time-consuming and laborious; and the contact plate of the patent needs to turn the screw for manual adjustment, which is not only time-consuming and laborious, but also will further increase the detection time and low detection efficiency. Therefore, there is an urgent need to provide an oil pump leakage detection device that can solve the above problems. Utility Model Content

[0033] Embodiment 1:

[0034] See attached Figure 1An oil pump leakage detection device comprises a detection box 1, wherein the top of the detection box 1 is provided with an opening 11, and the front side of the detection box 1 is provided with an inlet and outlet 12; a movable baffle 2, wherein the movable baffle 2 is slidably mounted on the inlet and outlet 12, and is used to slide upward to open the inlet and outlet 12 or slide downward to close the inlet and outlet 12; a moving platform 3, wherein the moving platform 3 is slidably connected to the bottom wall of the detection box 1, and is used to carry the oil pump and move the oil pump into the detection box 1 or out of the detection box 1 through the inlet and outlet 12; an elastic push rod 4, wherein the elastic push rod 4 is inserted into the bottom wall of the detection box 1, and ... It is arranged on the movable baffle 2, and is used to provide a backward elastic pressing force for the oil pump; two pressing assemblies 5, which are symmetrically installed on the left and right side walls of the detection box 1 and move synchronously, and are used to contact, press or disengage the left and right sides of the oil pump at the same time; an air inlet 6, which is arranged on the rear side wall of the detection box 1, and is used to introduce high-pressure gas into the oil pump after being sealed with the oil pump; a drain pipe 13, which is arranged at the bottom of any side wall of the left side wall, the rear side wall, and the right side wall of the detection box 1, and is connected to the inside of the detection box 1. It can be seen from the above structure that the detection box 1 is used as a container for leakage detection, and the top of the detection box 1 is provided with an opening 11, which is used to allow the experimenter to directly observe whether there are bubbles in the detection box 1 from the top of the detection box 1 during the detection process. The movable baffle 2 is slidably installed on the inlet and outlet 12 provided on the front side of the detection box 1, and can be opened by sliding upward, or closed by sliding downward. Specifically, the movable baffle 2 and the detection box 1 can be slidably connected in a manner such as by cooperating with the baffle groove and the baffle slide bar arranged vertically. When the entrance and exit 12 are closed, the left side wall, the rear side wall, the right side wall, the bottom wall and the movable baffle 2 of the detection box 1 form a laterally closed detection chamber to ensure that no leakage occurs when liquid is subsequently injected into the detection box 1. The mobile platform 3 is slidably connected to the top of the bottom wall of the detection box 1 and can slide horizontally in the front-to-back direction. The mobile platform 3 is used to carry the oil pump and move the oil pump into the detection box 1 through the opened entrance and exit 12, and then perform an airtightness test, or move the oil pump out of the detection box 1 through the opened entrance and exit 12 after the test. Therefore, the utility model does not need to lift the oil pump to the top of the detection box 1, then move it into the oil pump, and then place it downward, which saves time and effort and can improve the detection efficiency. The elastic push rod 4 is penetrated on the movable baffle 2, which can provide a backward elastic tightening force for the oil pump moved into the detection box 1. The two clamping assemblies 5 are symmetrically mounted on the left and right side walls of the detection box 1 and move synchronously, and are used to contact, clamp or disengage the left and right sides of the oil pump at the same time. The elastic push rod 4 is used in conjunction with the two clamping assemblies 5 to position the front side and the left and right sides of the oil pump. As for the rear side of the oil pump, it is aligned with the air intake member 6 that penetrates the rear side wall of the detection box 1 and is sealed and fixedly connected. The air intake member 6 will pass high-pressure gas into the oil pump during the detection process to test the air tightness of the oil pump. Therefore, the utility model can also ensure that the oil pump does not shift during the detection process.Specifically, the air intake member 6 may include a pipe connecting the inside and outside of the detection box 1 and an air intake cover connecting the pipe and the air intake port provided on the oil pump, so that the air intake cover is sealed when connected to the air intake port of the oil pump. The drain pipe 13 is used to discharge the liquid inside the detection box 1 out of the detection box 1. Specifically, a valve may be provided on the drain pipe 13 to control the discharge. The drain pipe 13 may be provided at the bottom of any side wall of the left side wall, the rear side wall, and the right side wall of the detection box 1, so as to facilitate the liquid in the detection box 1 to be drained out. When testing the air tightness of the oil pump, the movable baffle 2 can be slid upwards to open the inlet and outlet 12, and the mobile platform 3 at the bottom of the test box 1 can be pulled forward, and then the oil pump can be placed on the mobile platform 3, and then the mobile platform 3 can be moved into the test box 1, and the air inlet 6 can be connected to the air inlet of the oil pump, and then the movable baffle can be slid downwards to seal the inlet and outlet 12, and the test liquid can be injected into the test box 1, and then the external air intake device can be used to inject high-pressure gas into the oil pump through the air inlet 6, and observe whether bubbles are generated in the test liquid to determine whether the oil pump has leakage. The utility model can ensure that the oil pump does not shift during the detection process, saves time and effort, and has high detection efficiency.

[0035] Embodiment 2:

[0036] See attached Figures 1 to 4 On the basis of the first embodiment, two baffle locking members 7 are also included; the two baffle locking members 7 are symmetrically arranged at the bottom of the front end of the left wall of the detection box 1 and the bottom of the front end of the right wall of the detection box 1; two matching members 21 are also included, and the two matching members 21 are symmetrically arranged at the bottom of the left and right side walls of the movable baffle 2; the baffle locking member 7 located on the left side wall of the detection box 1 corresponds to the matching member 21 arranged at the bottom of the left side wall of the movable baffle 2, and the baffle locking member 7 located on the right side wall of the detection box 1 corresponds to the matching member 21 arranged at the bottom of the right side wall of the movable baffle 2; the baffle locking member 7 is used to cooperate with the corresponding matching member 21 to lock the position of the movable baffle 2 or unlock the movable baffle 2 after the movable baffle 2 closes the entrance and exit 12. As can be seen from the above structure, after the movable baffle 2 slides downward to seal the entrance and exit 12, the baffle locking members 7 provided on the left and right side walls of the detection box 1 cooperate with the matching members 21 provided on the left and right sides of the movable baffle 2 to lock, further ensuring the sealing performance of the movable baffle 2 to the entrance and exit 12. When the entrance and exit 12 needs to be opened, it is only necessary to unlock the two baffle locking members 7 and the corresponding matching members 21 respectively to unlock the movable baffle 2, so that the movable baffle 2 can slide up and down.

[0037] The edge of the movable baffle 2 near the entrance 12 is also provided with a sealing strip. As can be seen from the above structure, the provision of the sealing strip can facilitate the edge of the movable baffle 2 to be close to the edge of the entrance, further improving the sealing effect and preventing liquid leakage inside the detection box 1.

[0038] The clamping assembly 5 includes a clamping block 51, a connecting block 52, a connecting rod 53, a driving member 54 and a supporting seat 55; the clamping block 51 is arranged at the lower end of the side of the connecting block 52 away from the side wall of the detection box 1, and the side wall of the clamping block 51 away from the connecting block 52 has an arc-shaped surface that is concave toward the connecting block 52; the upper end of the side of the connecting block 52 close to the side wall of the detection box 1 is connected to the end of the connecting rod 53; the connecting rod 53 is movably arranged on the top of the side wall of the detection box 1, and the end of the connecting rod 53 is located inside the detection box 1, and the front end of the connecting rod 53 passes through the side wall of the detection box 1 and extends outward; the front end of the connecting rod 53 is connected to the driving member 54; and a supporting seat 55 is also arranged below the driving member 54. It can be seen from the above structure that the supporting seat 55 is used to raise the height of the driving member 54, so that the connecting rod 53 connected to the driving member 54 is located at the top of the side wall of the detection box 1, which is higher than the liquid level of the detection liquid during detection. The driving member 54 can be a cylinder, which is used to drive the connecting rod 53 to move horizontally to the left or right. Since the upper end of the connecting block 52 close to the side wall of the detection box 1 is connected to the end of the connecting rod 53, and the clamping block 51 is arranged at the lower end of the connecting block 52 away from the side wall of the detection box 1, when the connecting rod 53 moves horizontally to the left or right, it will eventually drive the clamping block 51 to move horizontally to the left or right. In addition, since the clamping block 51 is arranged at the lower end of the connecting block 52, the position is relatively low, so that the clamping block 51 can be completely immersed in the liquid during detection, and the clamping block 51 corresponds to the position of the oil pump, and the clamping block 51 can be controlled by the driving member 54 to clamp the oil pump. Since the driving member 54 of the utility model can be a cylinder, the two clamping blocks 51 can be synchronously moved close to or away from the oil pump by means of electrical control, which not only saves time and effort, but also avoids the situation of uneven clamping force on both sides, and ensures the centering of the oil pump position.

[0039] A rubber pad 511 is also provided on the outer side of the arc surface of the pressing block 51. As can be seen from the above structure, the provision of the rubber pad 511 can avoid scratches on the surface of the oil pump and protect the oil pump.

[0040] The elastic push rod 4 includes a second connecting rod 41, a tightening block 42, a spring 43 and a limiter 44; the second connecting rod 41 is movably arranged in the center of the movable baffle 2; the rear end of the second connecting rod 41 is located inside the detection box 1, and the rear end of the second connecting rod 41 is connected to the tightening block 42; the spring 43 is wound around the outside of the second connecting rod 41, and the front and rear ends of the spring 43 are respectively connected to the tightening block 42 and the side of the movable baffle 2 close to the tightening block 42; the front end of the second connecting rod 41 is located outside the detection box 1, and the front end of the second connecting rod 41 is connected to the limiter 44. It can be seen from the above structure that the second connecting rod 41 penetrates the front and rear sides of the movable baffle 2 and can move forward or backward. The rear end of the second connecting rod 41 is located inside the detection box 1, and the rear end of the second connecting rod 41 is connected to a tightening block 42, which is used to press against the front end of the oil pump placed inside the detection box 1 to provide the oil pump with a backward elastic tightening force. Since the rear end of the oil pump is sealed with the air inlet 6, the front and rear directions of the oil pump can be fixed in the end. The spring 43 is wound around the outside of the second connecting rod 41, and the front and rear ends of the spring 43 are respectively connected to the tightening block 42 and the side of the movable baffle 2 close to the tightening block 42. When the spring 43 is compressed, it is compressed in the direction close to the movable baffle 2. When the spring is no longer compressed, it is reset in the direction away from the movable baffle 2. The front end of the second connecting rod 41 is located outside the detection box 1, and the front end of the second connecting rod 41 is also connected to a limiter 44, which is used to limit the position of the second connecting rod 41 moving backward to prevent the second connecting rod 41 from falling into the detection box 1.

[0041] Embodiment three:

[0042] See attached Figures 1 to 4 . On the basis of the second embodiment, the bottom wall of the detection box 1 is provided with two slide grooves which are respectively arranged on the left and right sides of the bottom wall of the detection box 1 and extend backward, and the two slide grooves are perpendicular to the bottom edge of the rear side wall of the detection box 1; the rear end of the bottom of the mobile platform 3 is provided with two slide rails; the slide rails correspond to the slide grooves one by one. It can be seen from the above structure that the mobile platform 3 realizes a sliding connection by cooperating with the slide grooves on the bottom wall of the detection box 1 through the slide rails arranged at the rear end of the bottom, and because the two slide grooves are perpendicular to the bottom edge of the rear side wall of the detection box 1, the mobile platform 3 can slide forward or backward in parallel with the side wall of the detection box 1.

[0043] The mobile platform 3 also includes two roller connectors 32 and two rollers 33 corresponding to the roller connectors 32; the front end of the bottom of the mobile platform 3 is also provided with a horizontal plate 31; the front ends of the two roller connectors 32 are rotatably connected to the rear side wall of the horizontal plate 31; each roller 33 is rotatably mounted on the end of a roller connector 32; the roller connector 32 is used to rotate downward to be in an extended state so that the roller 33 assists the mobile platform 3 to move forward or backward horizontally, or rotate upward to be in a folded state and stored at the rear side of the horizontal plate 31. As can be seen from the above structure, the foldable roller 33 is arranged at the front end of the bottom of the mobile platform 3 to assist the front end of the mobile platform 3 to slide when the mobile platform 3 moves forward or backward horizontally, and the height of the roller connector 32 can be adaptively adjusted according to the distance between the mobile platform 3 and the ground or the horizontal plane where it is placed, so that the mobile platform 3 can remain horizontal as a whole, and avoid the situation where one side of the mobile platform 3 is over-pressed due to uneven force and deformed and tilted. When the mobile platform 3 is put into the detection box 1, the roller 33 can be folded to the rear side of the horizontal plate 31 by rotating the roller connector 32 upwards, thereby reducing the occupied area.

[0044] The rotation angle of the roller connector 32 is 0-90 degrees. As can be seen from the above structure, the rotation angle of the roller connector 32 is set to 0-90 degrees, so that when the roller connector 32 is rotated downward to the extended state, it is perpendicular to the mobile platform 3, and when the roller connector 32 is rotated upward to the folded state, it is parallel to the mobile platform 3.

[0045] The inspection box 1 is located above the bottom plate 8. As can be seen from the above structure, the bottom plate 8 is a base plate for each component and is disposed at the bottom of the inspection box 1, which can provide a sliding horizontal bottom surface for the mobile platform 3 or provide support for the support seat 55.

[0046] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
