[0030] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments.

[0031] As Figures 1-11 shown, an energy storage pump test system includes an environmental temperature control box 2; and further includes: A medium storage box 1, the medium storage box 1 is connected with a medium temperature control mechanism 3, the top of the medium storage box 1 is connected with a detection pipe fitting 4, the detection pipe fitting 4 extends into the environmental temperature control box 2, and one end of the detection pipe fitting 4 extending into the environmental temperature control box 2 is fixedly communicated with a first hose 404, and a first flange 405 is fixedly installed on the first hose 404; A second pipe body 5, the second pipe body 5 is fixedly communicated with the bottom of the medium storage box 1, and a solenoid valve is installed on the second pipe body 5, the second pipe body 5 extends into the environmental temperature control box 2, and one end of the second pipe body 5 extending into the environmental temperature control box 2 is fixedly communicated with a second hose 6, and a second flange 7 is fixedly installed on the second hose 6; A clamping and fixing mechanism 8, the clamping and fixing mechanism 8 is arranged at the bottom of the environmental temperature control box 2.

[0032] As Figure 3As shown, as a specific technical solution, a first support frame 101 is fixedly installed at the bottom of the medium storage tank 1, and a plurality of top ports 102 are provided at the top of the medium storage tank 1. Liquid can be added to the medium storage tank 1 through the top ports 102 or emptied using a liquid pumping device.

[0033] As Figure 1 As shown, as a specific technical solution, a second support frame 201 is fixedly installed at the bottom of the environmental temperature control box 2, and a box door 202 is provided at the front opening of the environmental temperature control box 2. The box door 202 is used for opening and closing the front opening of the environmental temperature control box 2, and the energy storage pump to be tested can be placed into or taken out of the environmental temperature control box 2 through the opening.

[0034] In specific implementation, a perspective window is provided on the box door 202 to observe the internal situation of the environmental temperature control box 2, which is used to judge whether there is any abnormality or leakage during the detection of the energy storage pump.

[0035] The environmental temperature control box 2 provides a working environment with different temperatures for the energy storage pump for operation detection in different temperature environments. An electric heater, a temperature sensor are provided in the environmental temperature control box 2 and connected to a low-temperature refrigerator to regulate the temperature inside the environmental temperature control box 2.

[0036] As Figure 1-2 As shown, as a specific technical solution, the medium temperature control mechanism 3 includes a mold temperature machine 301 and a cooling tower 308; the mold temperature machine 301 is connected to the cooling tower 308 through a cooling return pipe 306 and a cooling outlet pipe 307, and a hot water return pipe 302, a cold water return pipe 303, a hot water outlet pipe 304 and a cold water outlet pipe 305 are connected between the mold temperature machine 301 and the medium storage tank 1.

[0037] The medium temperature control mechanism 3 is used to regulate the temperature of the medium in the medium storage tank 1, and provide media with different temperatures for the circulating pump to be tested for operation detection of the circulating pump in media with different temperatures.

[0038] The specific adjustment of the temperature of the medium in the medium storage tank 1 by the medium temperature control mechanism 3 is as follows. When cooling the medium, the pump body in the mold temperature machine 301 extracts the medium liquid in the medium storage tank 1 through the cold water return pipe 303, inputs the medium into the cooling tower 308 through the cooling return pipe 306 for cooling, and the cooling tower 308 inputs the cooled medium into the mold temperature machine 301 through the cooling outlet pipe 307. The mold temperature machine 301 returns the cooled medium to the medium storage tank 1 through the cold water outlet pipe 305 to realize the cooling of the medium in the medium storage tank 1; when heating the medium, the pump body in the mold temperature machine 301 extracts the medium liquid in the medium storage tank 1 through the hot water return pipe 302, heats the medium by the mold temperature machine 301, and after heating, returns the heated medium to the medium storage tank 1 through the hot water outlet pipe 304 to realize the heating of the medium.

[0039] A temperature sensor is arranged inside the medium storage tank 1 to feedback the temperature condition inside it.

[0040] As Figure 3 As shown, as a specific technical solution, the detection pipe fitting 4 includes a first pipe body 401; one end of the first pipe body 401 is fixedly communicated with the top of the medium storage tank 1, and a valve 402 and an electromagnetic flowmeter 403 are arranged on the first pipe body 401.

[0041] When the energy storage pump is detected, the water inlet end of the energy storage pump is connected to the second flange 7, and the water outlet end of the energy storage pump is connected to the first flange 405; the energy storage pump works, and the medium in the medium storage tank 1 is extracted through the second hose 6 and the second pipe body 5, and then input into the top of the medium storage tank 1 through the first pipe body 401, wherein the electromagnetic flowmeter 403 measures the flow rate and flow velocity of the medium discharged by the energy storage pump to judge whether the medium is transported normally.

[0042] Under different external temperatures and different medium temperatures, detect whether the energy storage pump can maintain normal flow rate and flow velocity for transporting the medium, and the duration of maintenance, so as to realize the durability test experiment of the energy storage pump.

[0043] During the specific test process, at a fixed external temperature, adjust the medium temperature and detect the flow condition; Figure 11 Shown in the figure are the data of the detection of the transport flow condition of the system at a fixed external temperature and different medium temperatures.

[0044] As Figures 5-6 As shown, as a specific technical solution, the clamping and fixing mechanism 8 includes an end frame 801 and a fixing frame 803; both the fixing frame 803 and the end frame 801 are fixedly installed on the bottom outer wall of the environmental temperature control box 2, a central shaft 804 is rotatably installed on the fixing frame 803, both ends of the central shaft 804 are fixedly connected with a stud 805, and the thread directions of the studs 805 at both ends of the central shaft 804 are opposite, a nut 806 is threadedly connected to the stud 805, the top of the nut 806 is fixedly installed with a sliding seat 807, a bottom groove 203 is opened on the bottom wall of the environmental temperature control box 2, the sliding seat 807 is slidably connected with the bottom groove 203, and the sliding seat 807 penetrates through the bottom groove 203, the top of the sliding seat 807 is fixedly installed with a clamping plate 808, a plurality of evenly distributed pressing strips 8081 are fixedly installed on the clamping plate 808, and an interval groove is formed between adjacent pressing strips 8081; the end of the stud 805 away from the central shaft 804 is rotatably connected to the end frame 801, and a motor 802 is fixedly installed on one of the end frames 801, and the output shaft of the motor 802 is fixedly connected to the end of the stud 805.

[0045] When the energy storage pump is placed in the environmental temperature control box 2 for testing, the energy storage pump is clamped and fixed by the clamping and fixing mechanism 8; specifically, the energy storage pump is placed between the two clamping plates 808 of the clamping and fixing mechanism 8, and the motor 802 drives the two stud bolts 805 and the central shaft 804 to rotate together. The stud bolt 805 is screwed with the nut 806, and with the sliding guide of the sliding seat 807 and the bottom groove 203, the nut 806, the sliding seat 807 and the clamping plate 808 move laterally together. Since the thread directions of the two stud bolts 805 are opposite, the two clamping plates 808 move closer to each other or move away from each other. When driving the clamping plates 808 to move closer to each other, the energy storage pump can be clamped and fixed.

[0046] After the test, the clamping and fixing of the energy storage pump is released by driving the two clamping plates 808 to move away from each other.

[0047] Through the above design, the automatic fixing and automatic release of the limit clamping of the energy storage pump are realized. When installing and disassembling the energy storage pump, there is no need for manual fixing and limiting and releasing the fixing and limiting operations, which reduces the labor intensity of workers and saves time and effort.

[0048] At the same time, the main structure of the entire clamping and fixing mechanism 8 is located outside the environmental temperature control box 2, and only the clamping plate 808 is arranged inside the environmental temperature control box 2, avoiding the influence of the temperature inside the environmental temperature control box 2 on the clamping and fixing mechanism 8 and reducing its service life.

[0049] Furthermore, heat insulation structures are arranged inside the box wall and the box door 202 wall of the environmental temperature control box 2 to reduce heat transfer and further reduce the influence of the outside on the temperature inside the environmental temperature control box 2.

[0050] As Figures 7-8 shown, as a specific technical solution, the sliding seat 807 includes a sleeve 8071; the top end of the sleeve 8071 is fixedly connected to the bottom of the clamping plate 808. The sleeve 8071 is located inside the bottom groove 203. The bottom opening of the sleeve 8071 is fitted and connected with a positioning square column 8073. The bottom end of the positioning square column 8073 is fixedly connected to the top surface of the nut 806. A first spring 8072 is sleeved between the positioning square column 8073 and the bottom end of the sleeve 8071. A fixing plate 8074 is fixedly installed on the outer side wall of the sleeve 8071. The fixing plate 8074 is elastically connected to the top surface of the nut 806 through the first spring 8072.

[0051] As Figures 6-9 shown, as a specific technical solution, a heat insulation sealing plate 9 is fixedly installed on the sleeve 8071 of the sliding seat 807. The top surface of the heat insulation sealing plate 9 abuts against the lower part of the bottom groove 203. The heat insulation sealing plate 9 includes a housing 901; a heat insulation layer 902 is filled in the housing 901.

[0052] Among them, the first spring 8072 is in a compressed state, and the compression elastic force of the first spring 8072 acts on the sleeve 8071, so that the heat insulation sealing plate 9 on the sleeve 8071 presses below the bottom groove 203, ensuring the sealing effect on the bottom groove 203. At the same time, the heat insulation sealing plate 9 can insulate heat, preventing the environmental temperature control box 2 from exchanging heat with the outside through the bottom groove 203 and reducing the loss of cold or heat in the environmental temperature control box 2.

[0053] The heat insulation sealing plate 9 has sufficient length on both the left and right sides of the sliding seat 807. When the heat insulation sealing plate 9 moves left and right horizontally with the sliding seat 807, the heat insulation sealing plate 9 always seals the bottom groove 203.

[0054] As Figures 8-9 shown, as a specific technical solution, a gap 903 is formed between the heat insulation layer 902 and the inner wall of the top of the outer shell 901 of the heat insulation sealing plate 9. A number of evenly distributed oil outlet fine holes 11 are opened at the top of the outer shell 901 of the heat insulation sealing plate 9, and the oil outlet fine holes 11 are communicated with the gap 903. The gap 903 is connected with a lubricating oil injection mechanism 10.

[0055] The lubricating oil injection mechanism 10 injects lubricating oil into the gap 903, and the oil is discharged through the oil outlet fine holes 11 to provide lubrication for the top surface of the heat insulation sealing plate 9. When the heat insulation sealing plate 9 moves left and right, the heat insulation sealing plate 9 rubs against the bottom surface of the environmental temperature control box 2. Through the above lubrication design, the friction and wear are reduced.

[0056] As Figures 8-10 shown, as a specific technical solution, the lubricating oil injection mechanism 10 includes an oil tank 1001, a conveying part and a driving part; the oil tank 1001 is fixedly installed at the bottom of the heat insulation sealing plate 9, and an oil filling port is arranged on one side of the oil tank 1001. The bottom of the oil tank 1001 is connected with the conveying part, and the conveying part is connected with the driving part.

[0057] The conveying part includes a conveying cylinder 1002; the conveying cylinder 1002 is fixedly installed at the bottom of the heat insulation sealing plate 9. A piston 1007 is fitted and connected inside the conveying cylinder 1002. An oil cavity is formed by the inner wall of the conveying cylinder 1002 and one side of the piston 1007. A first one-way valve 1005 and a second one-way valve 1006 are arranged at one end of the conveying cylinder 1002. One end of the first one-way valve 1005 and one end of the second one-way valve 1006 are both communicated with the oil cavity. The first one-way valve 1005 and the second one-way valve 1006 are respectively connected with a first oil pipe 1003 and a second oil pipe 1004. The first oil pipe 1003 is fixedly communicated with the bottom of the oil tank 1001, and the second oil pipe 1004 is communicated with the gap 903.

[0058] The driving part includes a connecting rod 1010; a cavity is provided inside the clamping plate 808, the connecting rod 1010 is arranged in the cavity, a communication groove 12 is provided between the clamping plate 808 and the sleeve 8071, the connecting rod 1010 penetrates through the communication groove 12, and the connecting rod 1010 extends into the sleeve 8071. A movable rod 1008 is fixedly connected to the bottom end of the connecting rod 1010. The movable rod 1008 penetrates through a hole provided on one side of the sleeve 8071, and the movable rod 1008 is fixedly connected to the piston 1007. A plurality of guide posts 1011 are fixedly installed in the cavity of the clamping plate 808. The guide posts 1011 are in clearance fit connection with guide holes provided on the connecting rod 1010. A second spring 1012 is sleeved on the guide posts 1011. The cavity wall and the connecting rod 1010 are elastically connected through the second spring 1012. A movable column 1009 is fixedly installed at the top end of the connecting rod 1010. The movable column 1009 penetrates through a through hole provided on one side of the clamping plate 808, and the movable column 1009 passes through the spacing groove between the pressing strips 8081.

[0059] As Figure 10 shown, when the clamping plate 808 does not clamp and fix the energy storage pump, the movable column 1009 extends out from the spacing groove between the pressing strips 8081; during the process of clamping and fixing the energy storage pump, before the clamping plate 808 contacts the side of the energy storage pump, the end of the extended movable column 1009 first contacts the side of the energy storage pump. Continuing to clamp will provide extrusion for the movable column 1009, causing the movable column 1009 to be received into the spacing groove, and the movable column 1009 drives the connecting rod 1010 to move. The movement of the connecting rod 1010 is guided by the guide posts 1011 and the guide holes, and the second spring 1012 is compressed. Further, the connecting rod 1010 drives the piston 1007 to move through the movable rod 1008. The piston 1007 extrudes the oil in the oil cavity, and the oil is input into the inter-groove 903 through the second one-way valve 1006 and the second oil pipe 1004, realizing automatic injection of lubricating oil to achieve automatic lubrication.

[0060] When the clamping plate 808 separates from the energy storage pump to release the energy storage pump, the movable column 1009 loses extrusion. Through the elastic force of the second spring 1012, the connecting rod 1010 and the movable column 1009 are reset. The movable column 1009 extends out from the spacing groove and returns to the state as Figure 10 shown. The connecting rod 1010 drives the piston 1007 to reset through the movable column 1009, so that the volume of the oil cavity increases. The oil cavity extracts the oil in the fuel tank 1001 through the first one-way valve 1005 and the first oil pipe 1003 to realize oil replenishment and prepare for the next lubrication.

[0061] Through the above design, by means of the extrusion force generated by clamping the energy storage pump, the lubricating oil injection mechanism 10 is driven to realize automatic oil injection lubrication, without manual operation and without an additional power source.
