DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] See also Figure 1 and Figure 2A movable intelligent heating device for a flow battery electrolyte tank comprises: a human-machine interface 1 and a motor 2 connected to its lower end, wherein the output shaft of the motor 2 is provided with a central shaft 4 through a connecting shaft 3, and the central shaft 4 is a hollow structure.

[0035] The human-machine interface 1 is an existing device, made of special waterproof and anti-corrosion materials, can work normally in an electrolyte environment, and can display electrolyte temperature, device operating status (such as motor 2 speed, resistance wire power, etc.), heating time and other information in real time; the operator can realize multiple functions through touch operation, such as setting temperature target value, adjusting motor 2 speed, starting or stopping heating device, etc.; at the same time, the human-machine interface 1 also has historical data recording and query functions, which is convenient for analyzing and optimizing the heating process. It should be noted that a rectangular plate is provided at the lower end of the motor 2, and each of the four corners of the rectangular plate has a hole, and the rectangular plate is used to connect with the electrolyte tank or the external lifting drive source through bolts.

[0036] See also Figure 1 , Figure 2 and Figure 5 The side wall of the central shaft 4 is provided with storage grooves 40 which are evenly arranged along its circumference and connected with its inner cavity. A main heating rod 5 is hinged near the upper end of the storage groove 40. A triangular support group 7 is installed at the lower end of the central shaft 4. A central rod 6 is installed at the top of the inner wall of the central shaft 4 through a telescopic driving source (such as an electric telescopic rod), and an auxiliary support heating group 8 is installed on the central rod 6.

[0037] See also Figure 1 , Figure 2 and Figure 4 The auxiliary support heating group 8 includes a concave ring 80 that is slidably sleeved on the center rod 6 and is evenly arranged axially. A sliding assembly 81 is installed on the main heating rod 5. A diagonal support heating rod 82 is hinged between the concave ring 80 and the sliding assembly 81. When the main heating rod 5 is unfolded, it forms a triangle with the diagonal support heating rod 82 and the center rod 6.

[0038] See also Figure 1 , Figure 2 and Figure 4 A locking group 60 is provided between the central rod 6 and the inner wall of the central axis 4 for locking the concave ring 80 after the diagonal support heating rod 82 is unfolded. When the main heating rod 5 is unfolded, the locking group 60 locks the position of the concave ring 80, so that the main heating rod 5, the diagonal support heating rod 82 and the central rod 6 form a stable triangular structure, which not only improves the supporting connection stability of the main heating rod 5, but also increases the heating range of the heating device for the electrolyte of the liquid flow battery, achieving the effect of one machine with two uses.

[0039] See also Figure 4The end of the main heating rod 5 away from its hinged end is rollingly connected with a ball, and the ball is used to reduce the friction between the end of the main heating rod 5 and the storage groove 40 when the main heating rod 5 is expanded and contracted.

[0040] See also Figure 4 The central rod 6 is provided with a resistance wire (an existing part structure, not shown in the figure) made of the same heating material as the main heating rod 5 and the diagonal support heating rod 82.

[0041] See also Figure 2 and Figure 5 The central rod 6 is provided with an opening and closing driving group 61 for driving the main heating rod 5 to expand and contract; the lower end of the central rod 6 is provided with an opening and closing push-pull group 62 for driving the triangular support group 7 to expand and retract.

[0042] When the center rod 6 moves downward, the center rod 6 drives the triangular support group 7, multiple main heating rods 5 and multiple diagonal support heating rods 82 to fully unfold through the opening and closing drive group 61 and the opening and closing push-pull group 62, and locks the auxiliary support heating group 8 and the triangular support group 7 through the locking group 60 and the opening and closing push-pull group 62. When the center rod 6 moves upward driven by the telescopic drive source, the triangular support group 7, multiple main heating rods 5 and multiple diagonal support heating rods 82 are integratedly unfolded, locked and folded, thereby increasing the overall strength and stability of the heating device. After the triangular support group 7 is unfolded, it contacts the electrolyte tank of the liquid flow battery to support the lower end of the center axis 4, thereby improving the stability of the center axis 4 during rotation.

[0043] See also Figure 2 and Figure 4 The opening and closing drive group 61 includes a mounting plate 610 fixedly mounted on the center rod 6 and evenly arranged along its axial direction. The mounting plate 610 is provided with guide grooves 611 evenly arranged along its circumference. A displacement block 612 is slidably connected to the guide groove 611. A movable hinge 613 is hinged between the displacement block 612 and the main heating rod 5.

[0044] In the initial state, the main heating rod 5 is vertical. When the center rod 6 moves downward under the drive of the telescopic driving source, the center rod 6 drives the mounting plate 610 to move downward. When the mounting plate 610 moves downward, the main heating rod 5 is pushed to rotate along the hinge point of the main heating rod 5 through the movable hinge 613 until the main heating rod 5 is horizontal. At this time, the main heating rod 5 and the center axis 4 are vertical; when the center rod 6 moves upward under the drive of the telescopic driving source, the center rod 6 pulls the main heating rod 5 to be retracted through the mounting plate 610 and the movable hinge 613, so that the entire heating device has a rod-shaped structure, which is convenient for moving and switching between different electrolyte tanks, adapting to a variety of application scenarios, and improving the versatility and ease of use of the equipment.

[0045] See also Figure 2 and Figure 4 The sliding assembly 81 includes a guide rail 810 installed on the side wall of the main heating rod 5, and a sliding block 811 is slidably connected to the guide rail 810. The sliding block 811 is hinged to the diagonal heating rod 82, and a tension spring member 812 is installed between the sliding block 811 and the guide rail 810.

[0046] See also Figure 2 , Figure 4 and Figure 6 The locking group 60 includes a disk 601 mounted on the center rod 6 and arranged uniformly along its axial direction. The disk 601 corresponds to the concave ring 80 one by one. The lower end surface of the disk 601 is mounted with an insertion rod 602 arranged uniformly along its circumference. The inner wall of the center shaft 4 is mounted with a plurality of supporting components arranged uniformly along its axial direction. The supporting components correspond to the concave ring 80 one by one. The concave ring 80 is provided with a socket corresponding to the insertion rod 602 one by one and passing through the socket up and down. The socket extends to the supporting component. When the center rod 6 moves downward, the insertion rod 602 passes through the socket and is plugged into the supporting component.

[0047] When the main heating rod 5 is located in the storage groove 40, the diagonal heating rod 82 is stored in the central shaft 4. When the central rod 6 moves downward and drives the main heating rod 5 to rotate and unfold along the hinge through the opening and closing drive group 61, the main heating rod 5 drives the diagonal heating rod 82 to rotate. At this time, the concave ring 80 moves upward and moves to the top of the supporting assembly. At this time, the disk 601 and the insertion rod 602 are driven by the central rod 6 to insert the insertion rod 602 into the insertion hole. When the disk 601 contacts the horizontal section of the concave ring 80, the disk 601 The concave ring 80 is pushed to move downward, and the concave ring 80 drives the diagonal support heating rod 82 to move downward. The diagonal support heating rod 82 drives the sliding block 811 to slide along the guide rail 810 until the insertion rod 602 is plugged into the corresponding supporting assembly to lock the concave ring 80. At this time, the main heating rod 5 is horizontal, thereby realizing the integrated deployment and locking of the diagonal support heating rod 82 and the main heating rod 5, which not only improves the supporting connection stability of the main heating rod 5, but also increases the heating range of the heating device for the electrolyte of the flow battery.

[0048] See also Figure 6 and Figure 7 The supporting assembly includes a fixed cylinder 630 installed on the inner wall of the central axis 4 and evenly arranged along its circumference. A moving head 631 is slidably connected inside the fixed cylinder 630. A push spring 632 is installed between the moving head 631 and the fixed cylinder 630. The upper and lower ends of the moving head 631 away from the push spring 632 are both arc-shaped, and a socket is also provided on the moving head 631.

[0049] When the concave ring 80 moves upward and contacts the moving head 631, the concave ring 80 squeezes and pushes the moving head 631 into the fixed cylinder 630. When the concave ring 80 moves above the moving head 631, the moving head 631 is pushed to move below the concave ring 80 under the elastic force of the push spring 632. At this time, the retracting spring member 812 pulls the sliding block 811 toward the end of the guide rail 810 away from the hinged end of the main heating rod 5 under the action of its reset elastic force. The diagonal support heating rod 82 pulls the concave ring 80 upward under the action of the tension. When the disc 6 When 01 contacts the horizontal section of the concave ring 80, the disc 601 pushes the concave ring 80 to move downward. At this time, the concave ring 80 drives the diagonal support heating rod 82 to move downward, and the diagonal support heating rod 82 drives the sliding block 811 to slide along the guide rail 810 until the insertion rod 602 is plugged into the corresponding socket on the moving head 631 to lock the concave ring 80, realizing the integrated deployment and locking of the diagonal support heating rod 82 and the main heating rod 5, which not only improves the support connection stability of the main heating rod 5, but also increases the heating range of the heating device for the electrolyte of the flow battery.

[0050] See also Figure 3 and Figure 5 The triangular support group 7 includes a fixed plate 70 rotatably connected to the lower end of the inner wall of the central axis 4. The bottom of the fixed plate 70 is hinged with three support legs 71 evenly arranged along its circumference. In the initial state, the three support legs 71 are vertical, so that the heating device can be placed when not in use. When the central rod 6 moves downward under the drive of the telescopic drive source, the central rod 6 drives the opening and closing push-pull group 62 to move downward and push the three support legs 71 to expand into a triangular shape. When the central axis 4 is inserted into the electrolyte tank of the flow battery, the support legs 71 contact the bottom of the inner wall of the electrolyte tank of the flow battery, thereby supporting the lower end of the central axis 4 to prevent the lower end of the central axis 4 from swinging under the action of the rotating centrifugal force, thereby reducing the connection life between the central axis 4 and the connecting axis 3.

[0051] See also Figure 3 and Figure 5 The opening and closing push-pull group 62 includes a connecting plate 620 that is rotatably installed after the center rod 6 slides through the fixed plate 70. A support rod 621 is hinged between the lower end of the connecting plate 620 and the supporting leg 71. The center rod 6 drives the connecting plate 620 to move downward, and the connecting plate 620 pushes the supporting leg 71 to open through the support rod 621 to provide triangular support for the bottom of the center axis 4.

[0052] See also Figure 3 The lower end of the central shaft 4 is rotatably connected to a conical tube 622 , and the support legs 71 contact the inner wall of the conical tube 622 after being unfolded, thereby increasing the supporting force of the support legs 71 .

[0053] See also Figure 1-Figure 7Working principle: when the electrolyte tank needs to be heated, the operator moves the device above the electrolyte tank, aligns the device with the tank mouth with the help of an observation or auxiliary positioning device, and inserts the central axis 4 into the electrolyte tank, controls the human-machine interface 1 through the existing equipment, and then starts the telescopic drive source to drive the central rod 6 downward, so that the main heating rod 5 and the diagonal support heating rod 82 and the triangular support group 7 are unfolded. At this time, the human-machine interface 1 can be detachably connected to the electrolyte tank through a rectangular plate to ensure the stability of the device. At the same time, the central rod 6, the main heating rod 5 and the diagonal support heating rod 82 are energized and heated. After that, the motor 2 drives the central axis 4 to rotate at a set speed, and the central axis 4 drives the main heating rod 5 and the diagonal support heating rod 82 to rotate in the electrolyte to generate convection. The diagonal support heating rod 82 assists in stirring, so that the heated medium is heated more evenly, and heat is transferred quickly and evenly.
