Description

Technical Field

[0001] This utility model relates to the technical field of water vapor capture pump frame, and in particular to an easy-to-maintain ultra-low temperature water vapor capture pump frame. Background Technology

[0002] The cryogenic water vapor capture pump is a device used to remove water vapor molecules in a high vacuum environment. It is also called a vacuum cryogenic machine or a water vapor cryogenic trap. It is mainly used in high vacuum coating, aerospace vacuum low temperature environment simulation experiments and other occasions that require a deep low temperature environment.

[0003] The main function of cryogenic water vapor capture pumps is to solve the problem of residual gas in high vacuum environments. In high vacuum environments using oil diffusion pumps or molecular pumps, more than 80% of the residual gas is water vapor, oil vapor and other high-boiling-point gases. Mechanical pumps have low capacity and take a long time to remove these residual gases. Cryogenic water vapor capture pumps use cryogenic technology to condense and capture these water vapor molecules, thereby improving the vacuum level and system efficiency.

[0004] Cryogenic water vapor capture pumps typically consist of multiple equipment modules and a frame. The equipment modules generally include a compressor module, a cooling module, a gas storage module, a heat exchange module, a control module, and valve assemblies. These equipment modules are usually mounted on the frame, as shown below.

[0005] A search revealed patent CN220489380U, which discloses a lightweight frame for an ultra-low temperature water vapor capture pump. The frame includes two independent upper and lower frames, both constructed with angle iron. The lower frame houses a compressor module and a cooling module, while the upper frame contains a gas storage module, a five-stage heat exchange assembly, a control module, and a valve assembly. Compared to existing technologies, this invention offers the following advantages: using angle iron reduces the equipment weight by 20 kg, effectively lowering transportation costs; angle iron is easy to process, reducing equipment manufacturing costs. Since square tubes cannot be internally painted for rust prevention, they are prone to rust and corrosion after a certain period of use. In contrast, all parts of the angle iron can be painted for rust prevention, resulting in a longer equipment lifespan and rust-free operation.

[0006] However, the aforementioned cryogenic water vapor capture pump frame still has the following areas for improvement. For example, although its hollow design reduces the processing and transportation costs of the equipment, achieving a lightweight effect and facilitating maintenance, it provides poor protection for the equipment modules. During transportation and subsequent operation, the equipment modules inside the frame are prone to accidental collisions with the outside environment, causing malfunctions and damage to each module. At the same time, dust and impurities easily adhere to the equipment modules, which over time can have adverse effects or even damage. Overall, this will greatly reduce the service life of the cryogenic water vapor capture pump. Therefore, there is an urgent need for a maintenance-friendly cryogenic water vapor capture pump frame to solve the above-mentioned technical problems. Utility Model Content

[0007] This utility model discloses an easy-to-maintain ultra-low temperature water vapor capture pump frame. It features a sealing mechanism that allows the side plates to be inserted into the insertion slots during assembly, followed by the top cover. When installing the top cover, pulling up two levers compresses the springs, moving the abutment plate and thus the two sets of limit rods away from each other. The top cover is then closed. After closing, releasing the levers causes the springs to return, moving the abutment plate and limit rods back to their original positions until the limit rods penetrate the extension plate and engage with the limit grooves, thus securing the top cover. The top cover also presses the top of the side plates firmly, ensuring their stability. The equipment module is installed inside the rack body. In subsequent operations, the rack body, work door, side panels, and top cover can be combined to form a closed system, effectively protecting the equipment module inside the rack body, such as providing anti-collision and dust protection. If the equipment module malfunctions or is damaged, the work door can be opened, and the above assembly operation can be repeated in reverse. The top cover and side panels can be removed in sequence, making the front and sides of the rack body open. This greatly facilitates the user's maintenance and repair of the equipment module. In summary, the problems in the background technology are solved.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model discloses an easy-to-maintain ultra-low temperature water vapor capture pump frame, including a frame body. The top of the frame body is designed to be open. A working door is hinged to the front of the frame body. A locking mechanism is provided at the working door. A touch screen display is provided at the working door. Both sides of the frame body have through grooves extending to their tops. Insertion grooves extending to their tops are provided on the front, back, sides and bottom of the through grooves. Two limiting grooves are provided on both sides of the frame body.

[0010] The enclosure mechanism includes side plates and a top cover. Two side plates are provided, each engaging with an insertion slot. Two extension plates are provided on both sides of the top cover, and a mounting bracket is fixedly connected between the two extension plates. A pull rod, shaped like an inverted U, is movably inserted through the mounting bracket. Abutment plates are fixedly connected to both ends of the pull rod. Two limiting rods are provided on one side of each abutment plate, movably penetrating the extension plates and engaging with limiting slots. The bottom of the top cover is sealed and abuts against the top of the frame body and the top of the side plates. Multiple springs are provided between the abutment plates and the mounting bracket, with both ends of each spring fixedly connected to the abutment plates and the mounting bracket, respectively.

[0011] A partition mechanism is located inside the frame body.

[0012] Furthermore, a through-hole heat dissipation vent is provided on the side plate, and a dustproof mesh is provided at the heat dissipation vent.

[0013] Furthermore, each of the two side panels is fixedly connected to a lifting handle on its opposite side, and the side panels are made of high-strength engineering plastic material.

[0014] Furthermore, the top cover and the extension plate are fixedly connected by welding, and both the top cover and the extension plate are made of aluminum alloy.

[0015] Furthermore, the partition mechanism includes a support block and a partition body. There are four support blocks, which are fixedly connected to the four inner corners of the frame body. The top of the support block is provided with a slot. The bottom of the partition body is fixedly connected with four locking blocks, which are matched and engaged with the four slots respectively. The inside of the locking block is provided with a threaded groove. A limiting knob is provided through one side of the support block, and the limiting knob is screwed into the threaded groove.

[0016] Furthermore, the partition body is located near the middle of the frame body, and the partition body is made of fiberglass material.

[0017] The present invention has the following advantages over the prior art:

[0018] 1. This technical solution features a closed mechanism that allows the frame body, work door, side panels, and top cover to form a closed state during operation. This effectively protects the equipment modules inside the frame body, providing features such as anti-collision and dust protection. If a equipment module malfunctions or is damaged, the work door can be opened, and the top cover and side panels can be removed in sequence, making the front and sides of the frame body open. This greatly facilitates the user's maintenance and repair of the equipment modules, thereby significantly improving its practicality.

[0019] 2. This technical solution incorporates a partition mechanism, allowing some equipment modules to be installed on top of the partition body, while others are installed on the bottom of the rack body. This makes efficient use of the rack body's internal space, separating multiple equipment modules. When a device module below the partition body malfunctions or is damaged, the partition body can be quickly removed along with the equipment module, depending on the actual repair area. For example, if the repair area is above the partition, the top cover and side panels do not need to be removed. This expands the operable space above the module requiring repair, facilitating rapid maintenance and repair by the user and further improving its practicality. Attached Figure Description

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0031] Reference Figures 1-5 A maintenance-friendly ultra-low temperature water vapor capture pump frame includes a frame body 1. The top of the frame body 1 is designed with an open top. A working door 2 is hinged to the front of the frame body 1. A locking mechanism 3 is provided at the working door 2. A touch screen display 4 is provided at the working door 2. Both sides of the frame body 1 have through grooves 5 extending to the top. The front, back, sides and bottom of the through grooves 5 have insertion grooves 6 extending to the top. Both sides of the frame body 1 have two limiting grooves 7.

[0032] The closing mechanism 8 includes side plates 801 and a top cover 802. Two side plates 801 are provided, each engaging with the insertion slot 6. Two extension plates 803 are provided on both sides of the top cover 802. A mounting bracket 804 is fixedly connected between the two extension plates 803. A pull rod 805 is movably inserted through the mounting bracket 804. The pull rod 805 is in the shape of an inverted U-shape, and abutment plates 806 are fixedly connected to both ends of the pull rod 805. Two limiting rods 807 are provided on one side of 06. The limiting rods 807 move through the extension plate 803 and are matched and engaged with the limiting groove 7. The bottom of the top cover 802 is sealed and abutted against the top of the frame body 1 and the top of the side plate 801. Multiple springs 808 are provided between the abutment plate 806 and the mounting bracket 804. The two ends of the springs 808 are fixedly connected to the abutment plate 806 and the mounting bracket 804 respectively. The partition mechanism 9 is located inside the frame body 1.

[0033] A through-hole heat dissipation vent 809 is provided at the side panel 801, and a dustproof mesh 810 is provided at the heat dissipation vent 809; a lifting handle 811 is fixedly connected to the opposite side of the two side panels 801, and the side panels 801 are made of high-strength engineering plastic material; the top cover 802 and the extension plate 803 are fixedly connected by welding, and both the top cover 802 and the extension plate 803 are made of aluminum alloy material.

[0034] In the specific implementation process, during assembly, the side plate 801 can be inserted into the insertion slot 6, and the top cover 802 can be placed on top. When installing the top cover 802, pull up the two pull rods 805, which compresses the spring 808 and moves the abutment plate 806, thereby moving the two sets of limiting rods 807 away from each other. Then, put the top cover 802 on. After it is closed, release the pull rods 805, the spring 808 rebounds, and moves the abutment plate 806 and the limiting rods 807 back to their original positions until the limiting rods 807 penetrate the extension plate 803 and match and engage with the limiting slot 7, thus fixing the top cover 802. The top cover 802 can also press the top of the side plate 801 tightly to ensure the side plate 801 is securely attached. After ensuring the stability of plate 801, the equipment module can be installed inside the frame body 1. In subsequent operations, the frame body 1, work door 2, side plate 801, and top cover 802 can be combined to form a closed state, effectively protecting the equipment module inside the frame body 1, such as anti-collision protection and dust protection. If the equipment module malfunctions or is damaged, the work door 2 can be opened, and the above assembly operation can be repeated in reverse. The top cover 802 and side plate 801 can be removed in sequence, so that the front and sides of the frame body 1 are open. This greatly facilitates the user to perform maintenance and repair on the equipment module.

[0035] The side panel 801 has a through heat dissipation vent 809 to facilitate ventilation and heat dissipation of the equipment modules inside the rack body 1. The heat dissipation vent 809 is equipped with a dustproof net 810 to prevent dust and impurities from entering the interior of the rack body 1.

[0036] The lifting handle 811 is designed to facilitate the installation and removal of the side panel 801. The side panel 801 is made of high-strength engineering plastic material, which ensures the strength of the side panel 801 and also makes it lighter, reducing the weight of the entire frame.

[0037] The top cover 802 and the extension plate 803 are fixedly connected by welding to ensure that the top cover 802 and the extension plate 803 have high connection strength and stability. The top cover 802 and the extension plate 803 are both made of aluminum alloy to ensure that the top cover 802 and the extension plate 803 have high rigidity and are not easily deformed or damaged.

[0038] Two springs 808 are provided between the abutment plate 806 and the mounting bracket 804, and the two springs are symmetrically arranged about the axis of the pull rod 805.

[0039] Among them, the locking mechanism 3 can be a handle locking mechanism. Specific Implementation Example 2:

[0041] Reference Figure 4 and Figure 6In a preferred embodiment, the partition mechanism 9 includes a support block 901 and a partition body 902. There are four support blocks 901, which are fixedly connected to the four inner corners of the frame body 1. The top of the support block 901 is provided with a slot 903. The bottom of the partition body 902 is fixedly connected with four locking blocks 904. The four locking blocks 904 are matched and engaged with the four slots 903 respectively. The inside of the locking block 904 is provided with a threaded groove 905. A limiting knob 906 is provided through one side of the support block 901. The limiting knob 906 is screwed into the threaded groove 905.

[0042] The partition body 902 is located near the middle of the frame body 1, and the partition body 902 is made of fiberglass.

[0043] In the specific implementation process, some equipment modules can be installed on the top of the partition body 902, and others can be installed on the bottom of the rack body 1. The internal space of the rack body 1 can be used to separate multiple equipment modules. When the equipment module below the partition body 902 fails or is damaged, the top cover 802 and side plate 801 do not need to be removed. By loosening the multiple limit knobs 906 to separate them from the threaded grooves 905, the partition body 902 and the equipment modules on the partition body 902 can be quickly removed together, expanding the operable space above the equipment module that needs to be repaired, so as to facilitate the user to quickly repair and maintain the equipment module.

[0044] The partition body 902 is located near the middle of the frame body 1 so that it can evenly divide the interior of the frame body 1 into two installation cavities, which facilitates the reasonable layout and installation of multiple different equipment modules. The partition body 902 is made of fiberglass because in the ultra-low temperature water vapor capture pump frame, the fiberglass partition can effectively resist water vapor erosion and maintain structural stability.

[0045] The side plate 801 has two heat dissipation vents 809, which are located above and below the partition body 902, respectively.

[0046] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
