Description

Technical Field

[0001] This utility model relates to the field of pickup device technology, specifically to a foreign object pickup device for liquid nitrogen tanks. Background Technology

[0002] Liquid nitrogen tanks, as essential equipment for storing liquid nitrogen, are widely used in numerous fields such as medicine, scientific research, and bioengineering. During long-term use, foreign objects inevitably fall into the tank. These foreign objects come from various sources, including tools and container fragments accidentally dropped during sample handling, as well as debris from aging internal structural components.

[0003] Currently, methods for cleaning foreign objects inside liquid nitrogen tanks have many shortcomings. Traditional methods often involve manual retrieval using simple tools such as long tweezers and nets. However, the limited field of vision inside the liquid nitrogen tank makes it difficult to effectively pick up foreign objects, resulting in low cleaning efficiency. Therefore, we propose a device for picking up foreign objects inside liquid nitrogen tanks to facilitate the removal of impurities. Utility Model Content

[0013] Preferably, the upper side plate of the horizontal plate is provided with a mounting groove for detachably installing an inverted U-shaped cover plate, and a light strip is installed on the inverted U-shaped cover plate;

[0014] The inverted U-shaped cover plate is provided with a slanted groove for directing the light strip light source to illuminate outwards.

[0015] Preferably, the bottom of the horizontal plate is provided with a slot, and the top of the tray is fixedly connected with a plug for insertion into the slot.

[0016] Preferably, the upper end of the sleeve rod is provided with a rotating head.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Please see Figures 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0030] A foreign object pickup device for liquid nitrogen tanks, including:

[0031] Collect shovel 1, such as Figures 1-2 As shown, the collection bin 1 has an opening 11 on one side, and a sloping shovel edge 12 is provided at the edge of the opening 11 to prevent small debris from being swept into the collection bin 1 due to the thickness of the bin plate. This embodiment is an example. Figure 3 In terms of position, a central shaft 2 is fixedly installed at the axis of the collection bin 1. It should be noted that in this embodiment, the collection bin 1 is suitable for flat-bottomed liquid nitrogen tanks. Some liquid nitrogen tanks have a concave bottom wall. The collection bin 1 can be designed to fit against the concave surface according to its concave curvature to ensure that foreign objects are effectively swept into the bin.

[0032] like Figures 1-3 The structure shown has a sleeve rod 3 inserted outside the central shaft 2, and a pickup assembly 4 fixedly installed at the bottom of the sleeve rod 3, which can sweep the object to be picked up in the can into the collection bin 1.

[0033] Specifically, such as Figures 3-5 As shown in the structure, the pickup component 4 in this embodiment includes a horizontal plate 41 with a connecting hole 412 at its inner end, and a sleeve rod 3 is coaxially fixedly installed at the connecting hole 412. Based on the rotating head 31 provided at the upper end of the handheld sleeve rod 3, the sleeve rod 3 and the pickup component 4 can be swept along the axis.

[0034] Considering the need for easy replacement of the scraping unit 44 installed at the bottom of the horizontal plate 41, in this embodiment, as follows... Figure 4 and Figure 5 As shown, the scraping unit 44 includes a tray 441 with bristles 443 at the bottom, and a slot 413 at the bottom of the horizontal plate 41. The top of the tray 441 is fixedly connected to a plug 442 for insertion into the slot 413, which facilitates the replacement of the scraping unit 44.

[0035] To better detect foreign objects inside the container and provide a wider field of view, this implementation example... Figure 5As shown, the upper side plate of the horizontal plate 41 is provided with a mounting groove 411 for detachable installation of the inverted U-shaped cover plate 42, and the inverted U-shaped cover plate 42 is symmetrically provided with two inclined grooves 421 for illuminating the light source of the light strip 43 outward, which can observe the position of foreign objects around during rotation and facilitate the cleaning of foreign objects.

[0036] The working principle of the foreign object pickup device inside the liquid nitrogen tank in this embodiment is as follows: First, place the device directly inside the liquid nitrogen tank, observe the position of the foreign object, hold the central shaft rod 2 with one hand to keep the collection shovel 1 in a fixed position, and use the other hand to rotate the sleeve rod 3 to drive the scraping unit 44 to sweep the foreign object to complete the foreign object pickup action, and then remove it.

[0037] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0038] Furthermore, if the embodiments of this utility model involve descriptions such as "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
