A hydraulic pump with leak alarm capability

Abstract

This utility model relates to the field of hydraulic pump technology, specifically disclosing a hydraulic pump with a leakage alarm function. It includes a base plate with four fixing components on its top. A hydraulic pump body is fixedly mounted on top of these four fixing components. An oil inlet and an oil outlet are respectively located on both sides of one side of the hydraulic pump body. A connecting pipe is fixedly connected to one end of each oil inlet and outlet. When a leak occurs at the interface between the oil inlet / outlet and the connecting pipe, oil drips into a collection tank. The weight of the oil causes a miniature spring to deform, which in turn lowers the collection tank. The lowering of the collection tank, via a movable plate, movable rod, miniature spring, limiting plate, movable sleeve, slide groove, and slider, causes a flexible rubber block to descend, applying pressure to a pressure sensor. The pressure sensor then activates an alarm signal via a controller.

Description

Technical Field

[0001] This utility model relates to the field of hydraulic pump technology, specifically to a hydraulic pump with leakage alarm capability. Background Technology

[0002] A hydraulic pump is a power device that converts mechanical energy into hydraulic energy. It relies on changes in the sealed volume to draw in and pressurize oil. Specifically, it is driven by a prime mover such as an electric motor or engine, which causes the working parts inside the pump (such as gears, vanes, pistons, etc.) to move, thereby creating a periodic change in the sealed volume. By continuously repeating the oil drawing and pressing process, the mechanical energy input from the prime mover is converted into the pressure energy of the oil, providing power to the hydraulic system.

[0003] During long-term operation, hydraulic pumps are subjected to the impact of high-pressure oil, as well as the effects of vibration, temperature changes, and mechanical stress. As a result, the seals at the hydraulic pump interface will age and loosen, leading to oil leakage. The hydraulic pump will automatically alarm when oil leakage occurs, but it cannot collect the leaking oil. Since it takes time for staff to arrive after receiving the alarm signal, the oil will continue to leak during this period. The leaked oil will cause energy waste and environmental pollution. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a hydraulic pump with a leak alarm function, which has the advantages of centralized collection of leaked oil, thus solving the problem of energy waste and environmental pollution caused by oil leaks into the surrounding environment.

[0005] This utility model discloses a hydraulic pump with leakage alarm capability, comprising a base plate. Four fixing components are mounted on the top of the base plate, and a hydraulic pump body is fixedly mounted on top of the four fixing components. An oil inlet and an oil outlet are respectively provided on both sides of one side of the hydraulic pump body. A connecting pipe is fixedly connected to one end of each oil inlet and outlet. A leakage alarm component is located below the interface between the oil inlet / outlet and the connecting pipe. The leakage alarm component includes two second fixing plates, each with an internal cavity. A collection box is movably connected between the two cavities. Movable plates are fixedly mounted on both sides of the collection box, located outside the two second fixing plates. The internal cavities of the two movable plates... Both are connected by movable rods, with the bottom of the movable rods fixedly connected to the top of the base plate. A miniature spring is wound around the surface of each movable rod, with one end of the miniature spring fixedly connected to the bottom of the movable plate. The other end of the miniature spring is fixedly connected to a limiting plate, and one side of the limiting plate is fixedly connected to one side of a second fixed plate. The movable rod is fixedly disposed within the inner cavity of the limiting plate. A flexible rubber block is fixedly disposed at the bottom of the collection box, with a pressure sensor in contact with the bottom of the flexible rubber block. A controller is fixedly disposed below the pressure sensor, with the bottom of the controller fixedly connected to the top of the base plate. An alarm is disposed on one side of the controller, with the bottom of the alarm fixedly connected to the top of the base plate. When leaks occur at the inlet and outlet ports and the connecting pipe interfaces, the oil drips into the collection tank. The weight of the oil causes a miniature spring to deform, which in turn lowers the collection tank. A movable plate, movable rod, miniature spring, limit plate, movable sleeve, slide groove, and slider work together to lower the collection tank. This descent of the collection tank causes a flexible rubber block to descend, applying pressure to a pressure sensor. The pressure sensor then triggers an alarm signal via the controller. By incorporating a leak alarm component, timely alarm signals can be issued when leaks occur at the inlet and outlet ports and the connecting pipe interfaces. Furthermore, the collection tank allows for the centralized collection of leaked oil, preventing it from spilling into the surrounding environment and thus avoiding energy waste and environmental pollution.

[0006] This invention discloses a hydraulic pump with a leakage alarm function. The fixing assembly includes a fixing seat, a screw threadedly connected to the inner cavity of the fixing seat, a rotating handle fixedly located at one end of the screw outside the fixing seat, and a first fixing plate threadedly connected to the other end of the screw. The top of the first fixing plate is fixedly connected to the bottom of the hydraulic pump body. When disassembling the hydraulic pump body, rotating the limiting screw releases the limiting relationship between the rotating handle and the fixing seat. Rotating the rotating handle then drives the screw to rotate. When one end of the screw rotates out of the inner cavity of the first fixing plate, the limiting relationship with the first fixing plate is released. Releasing the limiting relationship with the first fixing plate releases the limiting relationship with the hydraulic pump body. The operation is simple, facilitating the disassembly, maintenance, or replacement of the hydraulic pump body, thereby reducing the maintenance cost of the hydraulic pump body.

[0007] This invention relates to a hydraulic pump with a leakage alarm function, wherein each of the four movable plates has a movable sleeve fixedly installed in its inner cavity, and the movable sleeve is movably connected to a movable rod. By using the movable sleeve to cooperate with the movable plates for movement, the stability of the movable plates is increased, and jamming during movement is avoided.

[0008] This utility model discloses a hydraulic pump with leakage alarm capability, wherein each of the four cavities has a sliding groove on both sides, and two collection boxes have sliders fixed on both sides of each side, which are adapted to the sliding grooves. By setting the sliding grooves and sliders, the stability of the collection boxes is increased, preventing the collection boxes from shifting or shaking during operation, thereby ensuring the stable operation of the leakage alarm.

[0009] This invention relates to a hydraulic pump with a leakage alarm function, wherein the inner cavity of the rotating handle is threadedly connected to a limiting screw, and the surface of the fixing seat is provided with a threaded hole adapted to the limiting screw. By setting the limiting screw and the threaded hole, the stability of the rotating handle is increased, preventing the rotating handle from rotating and causing the screw to loosen.

[0010] This invention relates to a hydraulic pump with a leakage alarm function, wherein the pump has multiple screw holes arranged in a ring at equal intervals on the surface of the mounting base. By using multiple screw holes in conjunction with a limit screw, the flexibility of the limit screw's positioning is increased, making it easier for operators to use.

[0011] This invention relates to a hydraulic pump with a leakage alarm function, wherein a drain pipe is provided on one side of the collection tank, and a valve is provided inside the drain pipe. The combination of the drain pipe and the valve facilitates oil discharge and increases ease of use.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When leakage occurs at the oil inlet and outlet interfaces with the connecting pipe, the oil drips into the collection tank. The weight of the oil causes a miniature spring to deform, which in turn lowers the collection tank. A movable plate, movable rod, miniature spring, limiting plate, movable sleeve, slide groove, and slider work together to lower the collection tank. This descent of the collection tank causes a flexible rubber block to descend, applying pressure to a pressure sensor. The pressure sensor then activates an alarm signal via a controller. By incorporating a leakage alarm component, timely alarm signals are issued when leakage occurs at the oil inlet and outlet interfaces with the connecting pipe. Furthermore, the collection tank allows for the centralized collection of leaked oil, preventing leakage into the surrounding environment and thus avoiding energy waste and environmental pollution.

[0014] 2. When disassembling the hydraulic pump body, this utility model allows for the rotation of the limiting screw to release the limiting between the handle and the fixed seat. Then, the handle is rotated, which drives the screw to rotate. When one end of the screw rotates out of the inner cavity of the first fixed plate, the limiting on the first fixed plate is released. Releasing the limiting on the first fixed plate releases the limiting on the hydraulic pump body. This operation is simple and facilitates the disassembly, maintenance, or replacement of the hydraulic pump body, thereby reducing the maintenance cost of the hydraulic pump body.

[0015] By setting up a movable sleeve to work with the movable board, the stability of the movable board is increased, and the situation of the movable board getting stuck during the movement is avoided.

[0016] By setting up chutes and sliders, the stability of the collection box is increased, preventing the collection box from shifting or shaking during operation, thereby ensuring the stable operation of the leak alarm.

[0017] By setting a limit screw and screw hole, the stability of the handle is increased, and the handle is prevented from rotating, which could lead to the screw loosening.

[0018] By setting multiple screw holes to work with the limit screw, the flexibility of the limit screw's limiting is increased, making it easier for staff to use.

[0019] By setting up a drain pipe and valve, the oil can be drained easily, increasing the ease of use. Attached Figure Description

Detailed Implementation

[0028] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0029] Please see Figure 1-6This utility model discloses a hydraulic pump with a leakage alarm, comprising a base plate 1, four fixing components 2 on the top of the base plate 1, a hydraulic pump body 3 fixedly mounted on the top of the four fixing components 2, an oil inlet 4 and an oil outlet 5 on both sides of one side of the hydraulic pump body 3, a connecting pipe 6 fixedly connected to one end of each oil inlet 4 and oil outlet 5, and a leakage alarm component 7 below the interface between each oil inlet 4 and oil outlet 5 and the connecting pipe 6, the leakage alarm component 7 comprising two second fixing plates 701, each second fixing plate 701 having a cavity 702 in its inner cavity, a collection box 703 movably connected between the two cavities 702, and movable plates 704 fixedly mounted on both sides of the collection box 703 and outside the two second fixing plates 701, the inner cavity of each movable plate 704 being connected through a movable rod 705, and the movable rod 705 being connected through the inner cavity of each movable plate 704. The bottom of the movable rod 705 is fixedly connected to the top of the base plate 1. A miniature spring 706 is wound around the surface of both movable rods 705. One end of the miniature spring 706 is fixedly connected to the bottom of the movable plate 704. The other end of the miniature spring 706 is fixedly connected to a limiting plate 707. One side of the limiting plate 707 is fixedly connected to one side of the second fixed plate 701. The movable rod 705 is fixedly installed in the inner cavity of the limiting plate 707. A flexible rubber block 716 is fixedly installed at the bottom of the collection box 703. A pressure sensor 711 is in contact with the bottom of the flexible rubber block 716. A controller 712 is fixedly installed below the pressure sensor 711. The bottom of the controller 712 is fixedly connected to the top of the base plate 1. An alarm 713 is installed on one side of the controller 712. The bottom of the alarm 713 is fixedly connected to the top of the base plate 1. When leakage occurs at the interfaces between the oil inlet 4 and the oil outlet 5 and the connecting pipe 6, the oil drips into the collection tank 703. The weight of the oil causes the miniature spring 706 to deform, which in turn causes the collection tank 703 to descend. The descending of the collection tank 703 is facilitated by the movable plate 704, movable rod 705, miniature spring 706, limit plate 707, movable sleeve 708, slide groove 709, and slider 710. The descent of the collection tank 703 causes the flexible rubber block 716 to descend, which applies pressure to the pressure sensor 711. Subsequently, the pressure sensor 711 can activate the alarm 713 via the controller 712 to issue an alarm signal. By setting up the leakage alarm component 7, an alarm signal can be issued in a timely manner when leakage occurs at the interfaces between the oil inlet 4 and the oil outlet 5 and the connecting pipe 6. At the same time, the collection tank 703 can collect the leaked oil in a concentrated manner, preventing the oil from leaking into the surrounding environment and thus avoiding energy waste and environmental pollution.

[0030] The fixing assembly 2 includes a fixing base 201, with a screw 202 threadedly connected to the inner cavity of the fixing base 201. A handle 203 is fixedly mounted on one end of the screw 202, located outside the fixing base 201. A first fixing plate 204 is threadedly connected to the other end of the screw 202. The top of the first fixing plate 204 is fixedly connected to the bottom of the hydraulic pump body 3. When disassembling the hydraulic pump body 3, rotating the limiting screw 205 releases the limiting relationship between the handle 203 and the fixing base 201. Then, rotating the handle 203 causes the screw 202 to rotate. When one end of the screw 202 disengages from the inner cavity of the first fixing plate 204, the limiting relationship with the first fixing plate 204 is released. Releasing the limiting relationship with the first fixing plate 204 releases the limiting relationship with the hydraulic pump body 3. This operation is simple and facilitates the disassembly, maintenance, or replacement of the hydraulic pump body 3, thereby reducing the maintenance cost of the hydraulic pump body 3.

[0031] Each of the four movable plates 704 has a movable sleeve 708 fixedly installed in its inner cavity, and the movable sleeve 708 is movably connected to the movable rod 705. By setting the movable sleeve 708 to cooperate with the movable plate 704 to move, the stability of the movable plate 704 is increased, and the situation of the movable plate 704 getting stuck during the movement is avoided.

[0032] Each of the four cavities 702 has a sliding groove 709 on both sides, and each of the two collection boxes 703 has a slider 710 fixed on both sides of its sides, which is adapted to the sliding groove 709. By setting the sliding groove 709 and the slider 710, the stability of the collection box 703 is increased, and the collection box 703 is prevented from shifting or shaking during operation, thereby ensuring the stable operation of the leakage alarm.

[0033] The inner cavity of the handle 203 is threadedly connected to a limiting screw 205, and the surface of the fixing base 201 is provided with a screw hole 206 that matches the limiting screw 205. By setting the limiting screw 205 and the screw hole 206, the stability of the handle 203 is increased, preventing the handle 203 from rotating and causing the screw 202 to loosen.

[0034] There are multiple screw holes 206, which are equidistantly arranged in a ring on the surface of the fixing base 201. By providing multiple screw holes 206 to work with the limiting screw 205, the flexibility of the limiting screw 205 in limiting is increased, making it easier for operators to use.

[0035] The collection box 703 has an oil drain pipe 714 on one side, and the inner cavity of the oil drain pipe 714 is equipped with a valve 715. By setting the oil drain pipe 714 and the valve 715 together, the oil is easily discharged, which increases the convenience of use.

[0036] When using this invention: when there is leakage at the interface between the oil inlet 4 and the oil outlet 5 and the connecting pipe 6, the oil drips into the collection tank 703. The weight of the oil causes the miniature spring 706 to deform, which in turn causes the collection tank 703 to descend. The descending of the collection tank 703 is facilitated by the movable plate 704, movable rod 705, miniature spring 706, limit plate 707, movable sleeve 708, slide groove 709, and slider 710. The descent of the collection tank 703 causes the flexible rubber block 716 to descend, which in turn applies pressure to the pressure sensor 711. Subsequently, the pressure sensor 711 can activate the alarm 713 via the controller 712 to send an alarm signal. By setting up the leakage alarm component 7, the leakage can be detected at the interface between the oil inlet 4 and the oil outlet 5 and the connecting pipe 6. When a leak occurs at the interface, an alarm signal is issued promptly. Simultaneously, the collection box 703 collects the leaked oil, preventing it from leaking into the surrounding environment and thus avoiding energy waste and environmental pollution. When disassembling the hydraulic pump body 3, rotating the limiting screw 205 releases the limit between the handle 203 and the fixed seat 201. Then, rotating the handle 203 causes the screw 202 to rotate. When one end of the screw 202 disengages from the inner cavity of the first fixed plate 204, the limit on the first fixed plate 204 is released. Releasing the limit on the first fixed plate 204 releases the limit on the hydraulic pump body 3. This simple operation facilitates disassembly, maintenance, or replacement of the hydraulic pump body 3, thereby reducing maintenance costs.

[0037] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
