[0002] Mudflat algae are an important component of marine ecosystems, playing a crucial role in ecological cycles. Collecting samples of mudflat algae helps scientists study their growth characteristics, seasonal variations, responses to environmental factors, and population dynamics. Analysis of this data can reveal the interactions between algae and their surrounding environment, thereby deepening our understanding of marine ecosystems.

[0003] The growth status of *Ulva prolifera* can serve as an indicator of the nutrient status and ecological quality of aquatic bodies. As an aquatic plant, *Ulva prolifera* is highly sensitive to changes in water quality. Regular sampling and analysis of *Ulva prolifera* can monitor environmental changes in aquatic waters, such as changes in nutrient concentrations and the impact of pollutants, thus providing a scientific basis for water environment management.

Detailed Implementation

[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] Example 1: This example aims to address the issue that tidal flats often have complex and varied topography, resulting in uneven distribution of *Ulva prolifera*. However, existing collectors cannot flexibly adjust their length, which may lead to uneven sample distribution and insufficient collection of *Ulva prolifera* in certain areas, affecting the representativeness of the samples. Please refer to [link to example]. Figures 1-4 A handheld, telescopic device for collecting seaweed from tidal flats includes a handle 110, an operation box 111, a telescopic rod 112, and a collection head 113 for collecting seaweed from tidal flats. The operation box 111 is mounted on the handle 110, the telescopic rod 112 is mounted on the operation box 111, and the collection head 113 is mounted on the end of the telescopic rod 112. A telescopic cavity 114 is provided inside the telescopic rod 112, and a telescopic assembly 120 for controlling the extension and retraction of the telescopic rod 112 is provided inside the telescopic cavity 114. A control switch 115 for controlling the telescopic assembly 120 is provided on the operation box 111, and a display screen 116 for displaying the length of the telescopic rod 112 is provided on the side of the operation box 111.

[0024] The telescopic pole 112 includes a first-stage pole 117, a second-stage pole 118, and a third-stage pole 119. The first-stage pole 117 is mounted on the control box 111, the second-stage pole 118 is movably mounted inside the first-stage pole 117, and the third-stage pole 119 is movably mounted inside the second-stage pole 118.

[0025] The telescopic assembly 120 includes a drive gear 121 disposed in the first-stage rod 117, a drive shaft 122 fixedly installed in the drive gear 121, a drive motor 123 controlled by the drive shaft 122 is driven at the bottom of the drive shaft 122, the drive motor 123 is electrically connected to the control switch 115, and a control rack 124 corresponding to the drive gear 121 is installed in the second-stage rod 118, the control rack 124 meshing with the drive gear 121.

[0026] A support plate 125 is fixedly installed on the side of the drive gear 121, and the upper end of the support plate 125 is fixedly installed on the inner wall of the third-stage rod 119. A first rack 126 is installed in the first-stage rod 117 and the second-stage rod 118, and a second rack 127 is installed in the third-stage rod 119. The first rack 126 and the second rack 127 are symmetrically arranged with the support plate 125 as the center. A groove 128 is opened in the support plate 125, and a mating gear 129 is inserted into the groove 128. The mating gear 129 meshes with the first rack 126 and the second rack 127.

[0027] The operator holds handle 110 and starts drive motor 123 via control switch 115. Drive motor 123 drives drive shaft 122 to rotate, and drive gear 121 rotates accordingly. Drive gear 121 meshes with control rack 124, controlling the extension and retraction of primary rod 117, including secondary rod 118. Simultaneously, mating gear 129 in support plate 125 meshes with first rack 126 and second rack 127, coordinating the extension and retraction of tertiary rod 119 within secondary rod 118. The operator adjusts the length of telescopic rod 112 via control switch 115 to adapt to different terrains and the distribution of seaweed. After the length of telescopic rod 112 is adjusted, display screen 116 on the side of control box 111 will display the current length of telescopic rod 112 in real time. After adjusting the length, align the collection head 113 with the area where the seaweed is distributed. The operator controls the movement of the collection head 113 through the handle 110 to collect seaweed samples. After the samples are collected, the operator stops the drive motor 123 through the control switch 115, and the telescopic rod 112 returns to its initial state. The operator can then safely retract the device.

[0028] In this embodiment: Through the telescopic design of the telescopic rod 112, the operator can flexibly adjust the length of the collection device according to the specific conditions of the tidal flat terrain and the distribution of seaweed, so that the device can effectively collect seaweed samples at different depths and distances, improving the representativeness of the samples. The control switch 115 and the display screen 116 on the operation box 111 provide precise control and real-time feedback on the length of the telescopic rod 112. The operation of the device is relatively simple. The operator only needs to hold the handle 110 and start and stop the drive motor 123 through the control switch 115 to realize the extension and retraction of the telescopic rod 112, reducing the complexity of operation and making it easy for even non-professionals to use.

[0029] Example 2 aims to address the issue of handle 110 slipping off in humid or sweaty conditions. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-4 A support rod 130 is installed at the bottom of the first rack 126 for fixation. The bottom end of the support rod 130 is fixedly installed to the inner wall of the operating box 111. A groove 133 corresponding to the drive shaft 122 is opened on the second-stage rod 118, and the drive shaft 122 slides in contact with the groove 133. The support rod 130 installed at the bottom of the first rack 126, with its bottom end fixedly installed to the inner wall of the operating box 111, enhances the stability of the structure and prevents the first-stage rod 117 and the second-stage rod 118 from shaking during extension and retraction.

[0030] Both the primary lever 117 and the secondary lever 118 are fitted with damping sleeves 131, which are fitted with rubber sleeves. The handle 110 is provided with anti-slip texture 132, which is a striped texture.

[0031] In this embodiment, the design of the damping sleeve 131 and the rubber sleeve provides additional damping effect, reducing the noise and vibration generated by the telescopic rod 112 during extension and retraction, improving the comfort and stability of operation. The anti-slip texture 132 increases the friction between the handle 110 and the operator's palm, maintaining a good grip even in wet or sweaty conditions, preventing the handle 110 from slipping, and improving the safety and comfort of operation.
