Description

Technical Field

[0002] The outdoor energy storage battery module is an energy storage device used in outdoor environments. It connects multiple energy storage battery units (such as lithium-ion batteries, lead-acid batteries, etc.) in series, parallel or a combination of series and parallel, and adds necessary battery management systems (BMS), protective casings, heat dissipation systems, connection interfaces and other components to form an energy storage system that can work stably in outdoor environments. The heat dissipation system of the battery module is generally carried out through ground cooling. By utilizing the relatively stable low temperature underground to efficiently dissipate heat, it saves energy and reduces consumption, is less affected by the environment, has high reliability, and helps to extend the life of the battery module.

[0003] When using existing outdoor energy storage battery modules that use floor cooling for heat dissipation, it is generally necessary to use a container for storing liquid as an intermediary to serve as a stable medium for liquid circulation, which helps to maintain the pressure balance of the entire heat dissipation system; however, during specific use, it is impossible to monitor the capacity of the heat exchange liquid in the container. If the liquid accidentally leaks during the heat exchange process, it will not only be impossible to detect it in time, but it will also affect the heat dissipation effect of the battery module and cause pollution to the surrounding environment, making the battery module more limited in use, thereby reducing the use effect and life of the battery module.

[0014] The present invention also provides a method for using an outdoor energy storage battery module using floor cooling and heat dissipation, comprising the following steps:

[0016] Step 2: When the battery pack in the battery box is in use, the heat generated by it will act on the surrounding heat sink and be conducted to the U-shaped tube bundle;

[0017] Step 3: Start two pumps, one of which is used as an input port and the other as an output port, so that the liquid in the container flows into the heat exchange tube deep underground through the output port, enters the U-shaped tube bundle, and then flows back into the container through the other input port;

[0018] Step 4: When the heat at the U-shaped tube bundle rises, the heat of the U-shaped tube bundle can be reduced because the liquid in the U-shaped tube bundle is cooled by the heat exchange tube deep underground;

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The liquid level in the container can be monitored by a number of distance measuring sensors, that is, the liquid capacity in the container can be monitored at all times. If the liquid is lost due to leakage or other factors during the circulation heat dissipation process of the battery module during use, it can be discovered in time, thereby avoiding the pollution of the surrounding environment due to the failure to timely discover the leakage of the cooling liquid during use. At the same time, the heat dissipation effect of the battery module is improved, thereby reducing the limitations of the module during use, not only avoiding damage to the battery block due to leakage, but also improving the use effect and life of the battery module;

[0022] (2) After the position adjustment of several distance measuring sensors is completed, the guide block is released, and the reset of the guide spring drives the displacement cross block to reset and move, so that the displacement lock block moves in the direction of the displacement square groove and enters it under the action of the displacement cylinder and the displacement spring, so that the displacement square column can be limited and set to avoid the distance measuring sensor from shaking or dislocation during use, further improving the use effect and monitoring accuracy of the distance measuring sensor, so that the distance measuring sensor can be used stably at the current position, reducing the limitations of the module during use;

[0023] (3) By moving the displacement square column up and down, the rotating cylinder can be driven to move in the rotating circular groove, so that the several distance measuring sensors on the disk on the rotating cylinder can be moved, so that the distance between the liquid surface and the several distance measuring sensors can be adjusted according to the different capacities in the container, avoiding the distance between the two being too large to affect the distance measuring time, thereby improving the monitoring accuracy, so that the effect of the module during use can be improved, so that the module can adjust the capacity in the container according to the heat dissipation scale when in use, reducing the limitations of the module during use, so that the liquid surface and the distance measuring sensor can maintain a good distance to detect the liquid level in the container, so that when the module uses floor cooling to dissipate heat, if the liquid in the U-tube bundle and the heat exchange tube leaks during circulation, it can be discovered and notified in the first time, avoiding damage to the module, thereby further improving its service life;

[0024] (4) When the distance measuring sensor is adjusted in position, the rotating cylinder moves, causing the limit slide groove on it to move along the limit block, which is used to limit the movement of the rotating cylinder, avoiding the shaking of the rotating cylinder when moving, thereby improving the stability of the distance measuring sensor when moving; at the same time, when the rotating cylinder moves, the limit spring will be in a buffering state. When the position of the rotating cylinder is limited, it means that the limit spring cannot be reset, so that the elastic force it brings acts on the rotating cylinder, thereby enhancing the friction and strength of the contact between the displacement square groove and the displacement lock block, avoiding the displacement lock block from dislocating the distance measuring sensor due to non-human factors, improving the safety of the distance measuring sensor when in use, and further reducing the limitations of the module when in use.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] Example, by Figures 1 to 11 The present invention comprises a workbench 1, which is arranged on the ground; a ground-cooling heat exchanger is arranged on the workbench 1; the ground-cooling heat exchanger comprises a battery box 2, the bottom of which is mounted on the top of the workbench 1 by bolts; the top of the battery box 2 is open, and a U-shaped tube bundle 3 is mounted on the inner wall of the opening; a battery block 4 is also mounted in the battery box 2, and a heat sink 5 is sleeved on the battery block 4, and the heat sink 5 is located between and in contact with the side wall of the battery block 4 and the U-shaped tube bundle 3; a container 6 is arranged at the bottom of the workbench 1, and a distance positioning component is arranged on the container 6, and the distance positioning component is used to monitor the liquid capacity in the container 6; a pump body 7 is installed at the opposite outer side walls of the container 6, and the opposite ends of the two pump bodies 7 are provided with pipes, one pipe is connected to the U-shaped tube bundle 3, and the other pipe is connected to a heat exchange tube 8, and the heat exchange tube 8 is composed of a plurality of U-tubes, and the heat exchange tube 8 is located in the deep soil; the heat exchange tube 8 is connected to the U-shaped tube bundle 3;

[0041] The workbench 1 is placed on the ground, and the heat exchange tube 8 is covered deep underground, so that the liquid in the heat exchange tube 8 is always in a low temperature state, and the heat carried by it will also be dissipated from deep underground; by starting the two pump bodies 7, one of the two pump bodies 7 is used as an input port and the other is used as an output port, so that the liquid in the container flows into the heat exchange tube 8 deep underground through the output port and enters the U-shaped tube bundle 3, so that the liquid in the container is in a circulation state, that is, the heat at the U-shaped tube bundle 3 is continuously dissipated through the flow of cooling liquid, so that the U-shaped tube bundle 3 is always in a low temperature state, so as to continuously reduce the temperature dissipated by the battery block 4 when in use, and The heat enters deep underground, which has the characteristics and effects of energy saving, high efficiency and environmental protection. When the battery block 4 in the battery box 2 is in use, the heat generated by it will act on the surrounding heat sink 5 and be conducted to the U-shaped tube bundle 3. When the heat at the U-shaped tube bundle 3 rises, the liquid in the U-shaped tube bundle 3 is cooled by the heat exchange tube 8 deep underground, so the heat of the U-shaped tube bundle 3 can be reduced. Since the liquid in the U-shaped tube bundle 3 is always in a flowing state, the heat generated by the battery block 4 when in use can be continuously taken away, so that the U-shaped tube bundle 3 is always in a cooling state, so that the heat of the battery block 4 can be continuously reduced, and the effect and life of the battery module when in use can be improved.

[0042] The distance measuring assembly of this embodiment includes an annular clamping plate 9 fixedly mounted on the outer wall of the container 6, and the annular clamping plate 9 is fixedly connected to the bottom of the workbench 1; a rotating circular groove 10 is provided on the top of the container 6, and the rotating circular groove 10 is connected to the inside of the container 6; a rotating cylinder 11 is slidably connected to the rotating circular groove 10, a rotating gear 12 is installed on the top of the rotating cylinder 11, and a displacement square column 13 is installed on the top of the rotating gear 12, and a plurality of vertically arranged displacement square grooves 14 are provided on both sides of the displacement square column 13; the bottom of the rotating cylinder 11 is located in the container 6 and A disc is also installed, and a plurality of distance measuring sensors are arranged on the side of the disc away from the top of the container 6; the distance measuring assembly also includes two displacement locking blocks 15 arranged opposite to each other, and the displacement square groove 14 is located on the moving path of the displacement locking block 15, and the two are in contact to achieve the locking of the displacement square column 13; the displacement locking block 15 is installed with two symmetrically arranged displacement cross blocks 16 on the side away from the displacement square column 13, and a displacement cylinder 17 is fixedly connected to the displacement cross block 16, and a displacement limit plate 18 is installed on the end of the displacement cylinder 17 away from the displacement square column 13; the two displacement cross blocks 16 are installed with a displacement cylinder 17 on the side away from the displacement square column 13; The block 16 is slidably connected with a displacement slider 19; a guide block 20 is symmetrically installed on both sides of the displacement slider 19, and a guide square column 21 is slidably connected to the guide block 20, and guide base plates 22 are installed at both ends of the guide square column 21, and the guide base plate 22 is fixedly installed on the top of the container 6; a locking unit is also provided on the guide block 20; a rotating groove 23 is provided on the inner side wall of the rotating circular groove 10, and a hollow annular block 24 is rotatably connected in the rotating groove 23, and the hollow annular block 24 is connected with the rotating groove 23; the inner side wall of the hollow annular block 24 is provided with a rotation ... A plurality of limit blocks 25 are installed on the side wall; the outer wall of the rotating cylinder 11 is provided with limit slots 26 of the same number and position as the limit blocks 25, and the limit slots 26 are slidably matched with the limit blocks 25; a limit cylinder 27 is installed in the limit slot 26, and a limit spring 28 is sleeved on the limit cylinder 27, one end of the limit spring 28 is fixedly connected to the limit block 25, and the other end is fixedly connected to the limit slot 26; the limit cylinder 27 is slidably matched with the limit block 25; the inner side wall of the hollow annular block 24 is arranged to fit the outer side wall of the rotating cylinder 11;

[0043] When the container 6 circulates the liquid in the U-shaped tube bundle 3 and the heat exchange tube 8, the liquid level in the container 6 is at a certain height because the liquid is in a circulating state. Through the action of a plurality of distance measuring sensors, the liquid level position in the container 6 can be monitored, that is, the liquid capacity in the container 6 can be monitored at all times. If the liquid is lost due to leakage or other factors during the circulation heat dissipation process of the battery module when in use, it can be discovered in time, thereby avoiding the pollution of the surrounding environment due to the failure to timely discover the leakage of the cooling liquid during use, and at the same time improving the heat dissipation effect of the battery module, thereby reducing the limitation of the module when in use, not only avoiding the damage to the battery block 4 due to leakage, but also improving the use effect and life of the battery module;

[0044] At the same time, the lengths of the U-tube bundle 3 and the heat exchange tube 8 used in different heat dissipation scales are also different, which makes the liquid capacity in the container 6 different. At this time, in order to avoid affecting the use effect of the distance sensor and ensure that it can detect the lack of liquid in the container 6 in time, it is necessary to reduce the detection time of the distance sensor. At this time, it is necessary to adjust the position of the distance sensor in time according to the different capacities of liquid to avoid the distance between the liquid surface and the distance sensor being too large, resulting in too long monitoring time and affecting the detection accuracy; at this time, by pulling the guide block 20 outward, it moves to the upper limit position of the guide square column 21, and drives the displacement slider 19 to move, so that it drives the displacement lock block 15 on the displacement cross block 16 to move under the action of the displacement spring 32 and the displacement cylinder 17, so that it no longer contacts the displacement square groove 14, thereby releasing the limit setting of the displacement square column 13, and then it can be passed. By moving the displacement square column 13 up and down, the rotating cylinder 11 can be driven to move in the rotating circular groove 10, so that the several distance measuring sensors at the disk on the rotating cylinder 11 can be moved, so that the distance between the liquid surface and the several distance measuring sensors can be adjusted according to the different capacities in the container 6, avoiding the influence of the distance between the two on the distance measuring time due to the large distance between the two, thereby improving the monitoring accuracy, so that the effect of the module when in use can be improved, so that the module can adjust the capacity in the container 6 according to the heat dissipation scale when in use, reducing the limitations of the module when in use, so that the liquid surface and the distance measuring sensor can maintain a good distance to detect the liquid level in the container, so that when the module uses floor cooling to dissipate heat, if the liquid in the U-shaped tube bundle 3 and the heat exchange tube 8 leaks during circulation, it can be discovered and notified in the first time, avoiding damage to the module, thereby further improving its service life;

[0045] After the position adjustment of the plurality of distance measuring sensors is completed, the guide block 20 is released, and the reset of the guide spring 33 drives the displacement cross block 16 to reset and move, so that the displacement lock block 15 is driven to move in the direction of the displacement square groove 14 and enter it under the action of the displacement cylinder 17 and the displacement spring 32, so that the displacement square column 13 can be limited and set, so as to avoid the distance measuring sensor from shaking or dislocation during use, further improving the use effect and monitoring accuracy of the distance measuring sensor, so that the distance measuring sensor can be used stably at the current position, reducing the limitations of the module during use;

[0046] It is worth mentioning that when the ranging sensor adjusts its position, the rotating cylinder 11 moves, causing the limiting slide groove 26 on it to move along the limiting block 25, which is used to limit the movement of the rotating cylinder 11, avoiding the rotating cylinder 11 from shaking when moving, thereby improving the stability of the ranging sensor when moving; at the same time, when the rotating cylinder 11 moves, the limiting spring 28 is in a buffering state. When the position of the rotating cylinder 11 is limited, it means that the limiting spring 28 cannot be reset, so that the elastic force it brings acts on the rotating cylinder 11, thereby enhancing the friction and strength of the contact between the displacement square groove 14 and the displacement locking block 15, avoiding the displacement locking block 15 from dislocating the ranging sensor due to non-human factors, thereby improving the safety of the ranging sensor when in use, and further reducing the limitations of the module when in use.

[0047] The displacement cross block 16 of this embodiment is also provided with a locking structure; the locking structure includes two locking tooth blocks 29 arranged opposite to each other, and the opposite back surfaces of the two locking tooth blocks 29 are respectively connected to the displacement cross blocks 16 on both sides of the top of the container 6; the tooth grooves on the side walls of the rotating gear 12 are located on the moving path of the locking tooth blocks 29; a positioning rack 30 is also installed at the bottom of the locking tooth block 29, and the positioning rack 30 is meshed and connected with a positioning gear 31, and a rotating force cleaning mechanism is provided on the positioning gear 31; a displacement spring 32 is sleeved on the displacement cylinder 17, one end of the displacement spring 32 is fixedly connected to the displacement limit plate 18, and the other end is fixedly connected to the displacement slider 19; a guide spring 33 is sleeved on the guide square column 21, one end of the guide spring 33 is fixedly connected to the guide base plate 22, and the other end is fixedly connected to the guide square block 20; the tooth height of the locking tooth block 29 is greater than the rotating gear 12;

[0048] When the displacement lock block 15 enters the displacement square groove 14 to limit the displacement square column 13, the locking tooth block 29 on the displacement cross block 16 will also move toward the direction of the rotating gear 12 and mesh with it, thereby limiting the rotating gear 12 to prevent the rotating gear 12 from rotating during use, resulting in the inability of the ranging sensor to stably detect the liquid level at the same position during use; at the same time, since the strength of the guide spring 33 is greater than the displacement spring 32, when the locking tooth block 29 has meshed with the rotating gear 12, the guide spring 33 has not yet reset to its position. Through the continued reset of the guide spring 33, the displacement slider 19 will continue to move, so that it moves within the upper limit of the displacement cylinder 17, so that the displacement spring 32 is in a buffering state, thereby strengthening the contact strength and friction between the locking tooth block 29 and the rotating gear 12, as well as the contact strength and friction between the displacement lock block 15 and the displacement square groove 14, thereby improving the limiting effect on the rotating gear 12 and the displacement square column 13;

[0049] At the same time, when the displacement lock block 15 needs to be disengaged from the displacement square groove 14 to release the limit of the displacement square column 13, the guide square block 20 will be pulled, so that the guide spring 33 is in a buffer state. Since the displacement spring 32 is originally in a buffer state, it is gradually reset. Only when the displacement spring 32 is reset, can it drive the locking tooth block 29 to move, thereby releasing the limit setting of the rotating gear 12. At this time, the positioning rack 30 can be moved and used to drive the rotating gear 12 to rotate, avoiding the rotation of the rotating gear 12 when the limit is set, and avoiding the phenomenon of the two being stuck; when the rotating cylinder 11 causes the rotating gear 12 to rotate when adjusting the height, At the same time, since the tooth height of the locking tooth block 29 is greater than that of the rotating gear 12, the rotating gear 12 is always located within the meshing range of the locking tooth block 29 to avoid dislocation between the two. At the same time, a position sensor can be installed on the same surface of the rotating gear 12 and the auxiliary rack 50. When the position of the rotating gear 12 changes, the auxiliary rack 50 will be driven to move synchronously, so that it can slide within the guide rail 48 through the guide rod 49. The guide rail 48 can pull the guide rod 49, so that the auxiliary rack 50 can always be in a state of meshing with the rotating gear 12, thereby avoiding dislocation of the two and causing the ranging sensor to be unable to rotate, thereby reducing the limitations of the module when used.

[0050] The lock control unit of this embodiment includes a locking base plate 34 fixedly mounted on the guide block 20, a locking rod 35 is slidably connected to the locking base plate 34, and a locking limit plate 36 is also installed at the end of the locking rod 35 away from the guide column 21; the top of the guide column 21 is provided with a plurality of equidistantly arranged locking grooves 37, one of which is located on the moving path of the locking rod 35; a locking spring 38 is sleeved on the locking rod 35, one end of the locking spring 38 is fixedly connected to the locking limit plate 36, and the other end is fixedly connected to the locking base plate 34;

[0051] When it is necessary to use the distance measurement assembly to adjust the height of the distance measuring sensor, the locking rod 35 is pulled upward to make it move within the upper limit on the locking base plate 34, so that the locking spring 38 is in a buffering state, so that the locking rod 35 is no longer located in the locking groove 37, thereby releasing the limit setting of the guide block 20, so that it can move normally and be used to adjust the height position of the distance measuring sensor; when the position adjustment of the distance measuring sensor is completed, the locking rod 35 is released, and the locking spring 38 is reset to drive the locking rod 35 to reset and move it, so that it enters the locking groove 37, thereby limiting the guide block 20, so that the distance measuring sensor cannot continue to adjust its position, and avoids the movement of the guide block 20 due to non-human factors when the distance measuring sensor is in use, which reduces the limitations of the module when used and improves the use effect of the distance measuring sensor.

[0056] Step 2: When the battery block 4 in the battery box 2 is in use, the heat generated by it will act on the surrounding heat sink 5 and be conducted to the U-shaped tube bundle 3;

[0057] Step 3: Start the two pump bodies 7, with one of the two pump bodies 7 serving as an input port and the other as an output port, so that the liquid in the container flows into the heat exchange tube 8 deep underground through the output port, enters the U-shaped tube bundle 3, and then flows back into the container 6 through the other input port;

[0058] Step 4: When the heat at the U-shaped tube bundle 3 rises, the heat of the U-shaped tube bundle 3 is reduced because the liquid in the U-shaped tube bundle 3 is cooled by the heat exchange tube 8 deep underground;
