Description

Technical Field

[0001] This utility model relates to the field of salvage technology, specifically a police-use strong magnetic salvage device. Background Technology

[0002] During the work of the water police, the retrieval of metal objects from the riverbed is a relatively common task. For example, physical evidence may be thrown into the river, or tourists may lose valuable items such as mobile phones and watches to the water while playing on the riverbank or taking a boat trip. These situations all require retrieval operations.

[0003] In the above scenarios, retrieval is relatively convenient when the location of the object's fall is relatively precise. However, in many cases, the location of the object in the river is less clear, which requires searching and retrieving a large area of ​​water. The original methods involved divers using frogmen to search, which required a lot of manpower and resources. Alternatively, a single strong magnet could be suspended by a rope and thrown into the water for dragging and magnetic attraction. However, the retrieval efficiency of a single strong magnet is limited. Therefore, a strong magnetic retrieval device that can efficiently search the bottom of the water is needed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a police-use strong magnetic retrieval device.

[0005] The specific technical solution is as follows:

[0006] A police-grade high-strength magnetic retrieval device includes multiple strong magnets, a fixing part, and a connecting part. The multiple strong magnets are fixedly connected to the fixing part and are arranged in a straight line. The fixing part and the connecting part are interconnected. The connecting part is used to connect a static rope. The connecting part is a rod and is fixed in the middle of the fixing part. The multiple strong magnets are fixed to the fixing part at equal intervals. A connecting ring is provided on the upper part of the connecting part. The fixing part is a plate and has multiple holes at equal intervals. The strong magnets are fixed in the holes by bolts. The device also includes two extension parts, which also have holes at equal intervals. The two extension parts are symmetrically fixed to the fixing part by bolts, and the strong magnets are fixed to the holes in the extension parts by bolts.

[0007] Furthermore, the fixing part is a plate and there are three of them. Each of the three fixing parts is provided with bolt holes. Multiple strong magnets are fixed at the bolt hole positions by bolts. The three fixing parts are located in the same straight line and are connected by bolts. The connecting part includes a set of adjusting rods and a connecting rod. The connecting rod is provided with a collar. The collar can slide radially along the connecting rod. One end of the set of adjusting rods is hinged to the collar. The other end of the set of adjusting rods is respectively hinged to one end of the two fixing parts. The top of the connecting rod is provided with a connecting ring.

[0008] Compared with the prior art, the technical solution proposed in this utility model achieves planar search by arranging multiple linear arrays and then having personnel use static ropes to lower the device into the water and pull it along the vertical direction of the strong magnetic linear array. This can effectively improve the efficiency of the search operation. At the same time, the width of the strong magnetic array at the bottom can also be adjusted appropriately. When the search area is wide, the work efficiency can be further improved. When the search area is narrow, such as a well, it can also prevent the operation from being impossible because the device is too large to be placed in the well. Attached Figure Description

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0010] Figure 1 This is a schematic diagram of the salvage device structure in Example 1.

[0011] Figure 2 This is a schematic diagram of the salvage device structure in Example 2. Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0013] In existing technologies, divers need to spend a lot of manpower and resources to search underwater, and the retrieval efficiency of a single strong magnetic field is limited. Therefore, there is a need for a strong magnetic retrieval device that can efficiently search the seabed.

[0014] To address the problems existing in the relevant prior art, this utility model proposes a police-use strong magnetic retrieval device. The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0015] A police-grade strong magnetic retrieval device includes multiple strong magnets 3, a fixing part 1, and a connecting part 2. The multiple strong magnets 3 are fixedly connected to the fixing part 1 and are arranged in a straight line. The fixing part 1 and the connecting part 2 are interconnected. The connecting part 2 is used to connect a static rope. In use, the static rope is tied to the connecting part 2, and the entire device is submerged in the water. Then, search personnel on the shore or a boat drag the device along the vertical direction of the straight line arrangement of the strong magnets. The strong magnets at the bottom attract the bottom of the water. After repeated pulling, a section of the bottom of the water can be quickly searched, and the metal parts that can be attracted and pulled out of the water can be retrieved from the bottom. Example 1

[0016] Please see Figure 1 In Embodiment 1, the connecting part 2 is a rod and is fixed in the middle of the fixing part 1. Multiple strong magnets 3 are fixed on the fixing part 1 at equal intervals. The upper part of the connecting part 2 is provided with a connecting ring 4.

[0017] The static rope is tied to the connecting ring and then pulled vertically along the fixed part. This causes multiple strong magnets fixed to the rod to move at the bottom of the water, which can effectively improve the search efficiency.

[0018] Meanwhile, when the water area to be searched is wide, in order to improve efficiency, the fixing part 1 can be made of plate. The fixing part 1 has multiple holes at equal intervals. The strong magnet 3 is fixed in the holes by bolts 5. It also includes two extension parts 6. The two extension parts also have holes at equal intervals. The two extension parts are symmetrically fixed to the fixing part 1 by bolts, and the strong magnet 3 is fixed in the hole position of the extension part 6 by bolts 5.

[0019] In the above scheme, the length of the overlapping part of the extension part 6 and the fixed part 1 is adjusted according to the specific width of the selected water area. The shorter the overlapping part, the more widening part there is. At least two holes overlap. The two holes can fix the strong magnet, and the bolts are also used to fix the extension part 6 and the fixed part 1 to each other. By adding extension parts 6 on both sides to widen the area, the search of the specified area can be performed more quickly. Example 2

[0020] Please see Figure 2The fixing part 1 is made of plate and there are three of them. For easy distinction, they are named the first fixing part 1a, the second fixing part 1b and the third fixing part 1c. Each of the three fixing parts 1 is provided with bolt holes. Multiple strong magnets 3 are fixed to the bolt hole positions by bolts 5. The three fixing parts 1 are located in the same straight line and are connected by bolts 5. The connecting part 2 includes a set of adjusting rods 2a and a connecting rod 2b. The connecting rod 2b is provided with a collar 9. The collar 9 can slide radially along the connecting rod 2b. One end of the set of adjusting rods 2a is hinged to the collar 9. The other end of the set of adjusting rods 2a is hinged to one end of the two fixing parts respectively. That is, the two adjusting rods 2a are hinged to one end of the first fixing part 1a and one end of the third fixing part 1c respectively. The top of the connecting rod 2b is provided with a connecting ring 4.

[0021] In the above embodiment, the length of the adjusting rod 2a is fixed, and the collar 9 slides up and down along the connecting rod 2b to adjust the lower part of the two adjusting rods 2a. The first fixing part 1a, the second fixing part 1b and the third fixing part 1c are bolted together in sequence, so that the entire fixing part can be adjusted. This makes adjustment more convenient while dealing with different water areas.

[0022] In the two implementations mentioned above, galvanized steel bars are used for the bar section to ensure a certain rigidity, while steel strips or rigid plastic strips are selected for the plate section. This ensures rigidity while also reducing weight, making the salvage operation more labor-saving.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
