Description

Technical Field

[0001] This utility model relates to the field of refrigerated container technology, specifically a flow regulation device for liquid cooling pipelines of container cold plates. Background Technology

[0002] Refrigerated containers are special containers with good insulation and the ability to maintain a certain low temperature, suitable for transporting and storing various perishable foods. They are specifically designed for transporting frozen or refrigerated goods that require maintaining a certain temperature. They are divided into internal mechanical refrigerated containers with built-in refrigeration units and external mechanical refrigerated containers without refrigeration units.

[0003] Utility model patent CN215247070U discloses a refrigerated container. The refrigerated container includes a container body, a door, a refrigeration unit, a door opening / closing sensor, a heat source sensor, and a controller. The controller is electrically connected to the door opening / closing sensor, the refrigeration unit, and the heat source sensor. The controller collects door opening and closing information through the door opening / closing sensor, and collects occupancy and vacancy information through the heat source sensor. Therefore, when the door is open, the refrigeration unit can be automatically stopped; when the door is closed and no one is inside the container, the refrigeration unit can be automatically restarted without manual operation.

[0004] When using refrigerated containers, multiple refrigeration plates are needed to refrigerate and insulate the container. Although the refrigerated container in the aforementioned patent improves automation efficiency, it is difficult to finely adjust the refrigeration effect of a single refrigeration plate. Due to the dense stacking of items inside the container, the refrigeration effect inside the container is easily poor. To address this issue, we provide a container cold plate liquid cooling pipeline flow regulation device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a flow regulation device for liquid cooling pipelines of container cold plates to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flow regulating device for liquid cooling pipeline of container cold plate, comprising a refrigeration plate and a regulating valve, wherein the regulating valve is provided with an regulating mechanism, the regulating mechanism comprising an regulating cone and a sealing ring, and the sealing ring is fixedly connected to the regulating valve, wherein an regulating sleeve is fixedly connected to the middle part of the regulating cone, and a power mechanism is provided outside the regulating valve, wherein the power mechanism comprises a worm gear.

[0007] Preferably, the input end of the refrigeration plate is fixedly connected to a connecting pipe, and the connecting pipe passes through the container and is fixedly connected to a regulating valve. The surface of the regulating valve is fixedly connected to a conveying pipe. Through the conveying pipe, the cold source of the main pipeline is diverted to the regulating valve, and through the connecting pipe, the cold source conveyed by the regulating valve is conveyed to the refrigeration plate.

[0008] Preferably, a first sealing ring is fixedly connected to the middle of the regulating valve, and the regulating sleeve is slidably connected to the inner ring of the first sealing ring. A limiting sleeve is sleeved on the outside of the regulating sleeve and the limiting sleeve is fixed to the surface of the regulating valve. The regulating sleeve is sealed by the first sealing ring to prevent the cold source flowing inside the regulating valve from seeping out.

[0009] Preferably, the adjusting sleeve has an internal threaded connection to a threaded rod, the other end of which is fixedly connected to a worm gear. A second sealing ring is fixedly connected to the middle of the limiting sleeve, and the threaded rod is rotatably connected to the second sealing ring. The threaded rod is sealed by the second sealing ring, thereby providing a secondary seal for the limiting sleeve and improving the sealing effect of the device.

[0010] Preferably, the limiting sleeve has a sliding groove inside, and a sliding block is slidably connected inside the sliding groove. The sliding block is fixedly connected to the adjusting sleeve. The position of the adjusting sleeve is limited by the sliding groove and the sliding block, thereby improving the stability of the lateral sliding of the adjusting sleeve.

[0011] Preferably, the surface of the limiting sleeve is fixedly connected to a fixed cover, and the worm wheel rotates inside the fixed cover. The fixed cover is rotatably connected to a worm, and the worm and the worm wheel are meshed together. By rotating the worm, the worm wheel is driven to rotate slowly, and there is a self-locking property between the worm and the worm wheel, which can be used to position the threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application uses a regulating valve to deliver refrigerant into the refrigeration plate, causing the refrigeration plate to generate a cold source to refrigerate and cool the container. By rotating a worm gear, the regulating sleeve is moved, which in turn drives the regulating cone to move. By controlling the distance between the regulating cone and the sealing ring, the flow rate of refrigerant delivered by the regulating valve is adjusted. By adjusting the flow rate of refrigerant, the refrigeration effect of the refrigeration plate is adjusted, thereby improving the accuracy of temperature regulation inside the container.

[0015] 2. This application uses a delivery pipe to divert the cold source from the main pipeline to the regulating valve, and a connecting pipe to deliver the cold source from the regulating valve to the refrigeration plate. The first sealing ring seals the regulating sleeve to prevent the cold source flowing inside the regulating valve from seeping out. The limiting sleeve positions the regulating sleeve to prevent it from shaking arbitrarily and improves the stability of the linear sliding of the regulating sleeve. The rotation of the threaded rod drives the regulating sleeve to move laterally inside the limiting sleeve, thereby adjusting the distance between the control regulating cone and the sealing ring.

[0016] 3. This application uses a second sealing ring to seal the threaded rod, thereby providing a secondary seal for the limiting sleeve and improving the sealing effect of the device. The sliding groove and sliding block limit the position of the adjusting sleeve, improving its lateral sliding stability. A fixed cover positions the worm and worm wheel; the worm's rotation drives the worm wheel to rotate slowly, and the worm and worm wheel have a self-locking function, allowing the threaded rod to be positioned after adjustment, improving the device's stability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a technical solution for a flow regulation device for liquid cooling pipelines of container cold plates.

[0024] Please see Figure 1 It includes a refrigeration plate 1 and a regulating valve 3. The regulating valve 3 delivers refrigerant into the refrigeration plate 1, so that the refrigeration plate 1 generates a cold source to refrigerate and cool the container.

[0025] The input end of the refrigeration plate 1 is fixedly connected to the connecting pipe 2, and the connecting pipe 2 passes through the container and is fixedly connected to the regulating valve 3. The surface of the regulating valve 3 is fixedly connected to the conveying pipe 4. Through the conveying pipe 4, the cold source of the main pipeline is diverted to the regulating valve 3, and through the connecting pipe 2, the cold source conveyed by the regulating valve 3 is conveyed to the refrigeration plate 1.

[0026] Please see Figure 1 , Figure 2 and Figure 4 The regulating valve 3 is equipped with an regulating mechanism 5, which includes an regulating cone 501 and a sealing ring 502. The sealing ring 502 is fixedly connected to the regulating valve 3. An regulating sleeve 503 is fixedly connected to the middle of the regulating cone 501. The regulating cone 501 is moved by the regulating sleeve 503. The refrigerant flow rate delivered by the regulating valve 3 is regulated by controlling the distance between the regulating cone 501 and the sealing ring 502.

[0027] A first sealing ring 504 is fixedly connected to the middle of the regulating valve 3, and the regulating sleeve 503 is slidably connected to the inner ring of the first sealing ring 504. A limiting sleeve 505 is sleeved on the outside of the regulating sleeve 503, and the limiting sleeve 505 is fixed to the surface of the regulating valve 3. The first sealing ring 504 seals the regulating sleeve 503 to prevent the cold source flowing inside the regulating valve 3 from seeping out. The limiting sleeve 505 positions the regulating sleeve 503 to prevent it from shaking randomly and improves the stability of the linear sliding of the regulating sleeve 503.

[0028] The adjusting sleeve 503 is internally threaded with a threaded rod 508. By rotating the threaded rod 508, the adjusting sleeve 503 is driven to move laterally inside the limiting sleeve 505, thereby adjusting the distance between the control adjusting cone 501 and the sealing ring 502.

[0029] A second sealing ring 509 is fixedly connected to the middle of the limiting sleeve 505, and the threaded rod 508 is rotatably connected to the second sealing ring 509. The threaded rod 508 is sealed by the second sealing ring 509, thereby providing a secondary seal for the limiting sleeve 505 and improving the sealing effect of the device.

[0030] The limiting sleeve 505 has a sliding groove 506 inside, and a sliding block 507 is slidably connected inside the sliding groove 506. The sliding block 507 is fixedly connected to the adjusting sleeve 503. The position of the adjusting sleeve 503 is limited by the sliding groove 506 and the sliding block 507, thereby improving the stability of the lateral sliding of the adjusting sleeve 503.

[0031] Please refer to it again. Figure 2 , Figure 3 and Figure 4 The regulating valve 3 is equipped with a power mechanism 6, which includes a worm gear 601. The other end of the threaded rod 508 is fixedly connected to the worm gear 601. The worm gear 601 drives the threaded rod 508 to rotate, thereby controlling the movement of the regulating sleeve 503.

[0032] The surface of the limiting sleeve 505 is fixedly connected to a fixed cover 602, and the worm gear 601 rotates inside the fixed cover 602. The worm 603 is rotatably connected inside the fixed cover 602, and the worm 603 meshes with the worm gear 601. The fixed cover 602 positions the worm 603 and the worm gear 601. The rotation of the worm 603 drives the worm gear 601 to rotate slowly. The worm 603 and the worm gear 601 have a self-locking function, which can position the threaded rod 508 after adjustment, improving the stability of the device.

[0033] A mounting bracket 605 is fixedly connected to the surface of the worm gear 601, and the mounting bracket 605 is assembled and connected to the container by bolts. A motor 604 is fixedly connected to the surface of the mounting bracket 605, and the output end of the motor 604 is fixedly connected to the worm 603. The position of the motor 604 is fixed by the mounting bracket 605, and the rotation of the worm 603 is controlled by the motor 604.

[0034] With the worm gear 603 and worm wheel 601 speed reduction transmission, the worm gear 603 does not require a large torque, and the electric motor 604 can use a small motor, which reduces the footprint of the device and improves the efficiency of resource utilization.

[0035] The electric motor 604 is electrically connected to the container refrigeration equipment. The electric motor 604 is started by the signal collected by the refrigeration equipment, and the flow of the corresponding regulating valve 3 is regulated. The electric motor 604 is prior art, and its detailed parameters and model will not be described in detail in this application.

[0036] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0037] In use, this invention involves first connecting the connecting pipe 2 to the refrigeration plate 1 and connecting the conveying pipe 4 to the main pipeline. The mounting bracket 605 is then installed on the container surface using bolts, and the position of the motor 604 is fixed. When the cold source flow rate needs adjustment, the motor 604 controls the rotation of the worm gear 603. The worm gear 603 and worm wheel 601 reduce speed and drive the threaded rod 508 to rotate inside the adjusting sleeve 503, causing the adjusting sleeve 503 to move the adjusting cone 501. This adjusts the distance between the adjusting cone 501 and the sealing ring 502. After adjustment, the self-locking capabilities of the worm gear 603 and worm wheel 601, and the self-locking capability of the threaded rod 508 within the adjusting sleeve 503, prevent the adjusting cone 501 from wobbling. By adjusting the refrigerant flow rate, the cooling effect of a single refrigeration plate is adjusted, improving the accuracy of temperature regulation inside the container.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
