Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical spraying technology, specifically to a telescopic nozzle for underwater pharmaceutical spraying. Background Technology

[0002] With economic development, my country's water environment faces multiple pressures, including water pollution, water shortages, and floods. Among these, water pollution exacerbates water shortages, and damage to the aquatic ecosystem leads to frequent floods. Currently, spraying boats are commonly used to treat and purify wastewater by spraying chemicals in lakes and rivers.

[0003] During the spraying process, multiple different agents need to be sprayed. If the first agent is not sprayed quickly enough, the second agent will react when they come into contact, which will reduce the efficacy or even make it ineffective. This is especially true for strong oxidizing agents and some reducing agents, which react and are consumed in the water before they come into contact with the sludge.

[0004] The existing technology of spraying pesticides on spraying boats only sprays pesticides from above the water surface during the spraying process. The pesticides tend to float to the surface, making it difficult for them to be sprayed and spread quickly in the water. Consequently, there is a waiting time before spraying a second pesticide, resulting in low work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a telescopic nozzle for underwater spraying of pesticides, so as to solve the problems in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A telescopic nozzle for underwater spraying of chemicals includes a fixed cylinder and a telescopic cylinder that are connected to each other, with the telescopic cylinder slidably connected inside the fixed cylinder; it also includes an electric cylinder for causing the telescopic cylinder and the fixed cylinder to slide relative to each other; the bottom of the telescopic cylinder is connected to an inverted frustum-shaped chemical outlet, the cone of the inverted frustum-shaped chemical outlet is set downwards, and multiple spray nozzles are provided on the conical surface of the conical chemical outlet.

[0007] Furthermore, the connection of one end of the electric cylinder to the fixed cylinder is specifically as follows: a sliding groove is provided on the side of the fixed cylinder, and a connecting block is installed at one end of the electric cylinder, with the connecting block passing through the sliding groove and fixedly connected to the telescopic cylinder.

[0008] Furthermore, an inner cylinder is fixedly connected to the fixed cylinder via a side plate, and the telescopic cylinder is sleeved on the outside of the inner cylinder.

[0009] Furthermore, it also includes a drug inlet tube, one end of which is fixedly connected to a mounting plate. The mounting plate is provided with external threads, and the top of the fixed cylinder is provided with internal threads. The mounting plate is connected to the top of the fixed cylinder by a threaded connection, so that the drug inlet tube and the fixed cylinder are detachably connected.

[0010] Furthermore, a blade is installed inside the spray nozzle, with the inward-facing end of the blade being the cutting edge and the outward-facing end being the back of the blade.

[0011] Furthermore, a locator is installed at the bottom of the drug outlet.

[0012] Compared with the prior art, this utility model has the following advantages and beneficial effects: The electric cylinder adjusts the relative positions of the fixed cylinder and the telescopic cylinder, thereby adjusting the extension and retraction of the agent outlet. This allows the agent outlet to extend underwater, spraying the agent from the nozzle into the water and preventing it from floating on the surface and hindering diffusion. The cone-shaped agent outlet has multiple spray nozzles on its conical surface, with the nozzle openings tilted downwards. This allows the agent to be sprayed diagonally downwards, ensuring faster contact with the agent even in deep waters and increasing the diffusion speed. Consequently, when spraying a second agent, the waiting time can be reduced, improving the overall efficiency of the spraying process. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0020] like Figures 1-3 As shown, a telescopic nozzle for underwater spraying of chemicals includes a fixed cylinder 1 and a telescopic cylinder 2 that are connected to each other, with the telescopic cylinder 2 slidably connected inside the fixed cylinder 1; it also includes an electric cylinder 3, which is used to make the telescopic cylinder 2 and the fixed cylinder 1 slide relative to each other; the bottom of the telescopic cylinder 2 is connected to an inverted frustum-shaped chemical outlet 6, with the cone of the inverted frustum-shaped chemical outlet 6 facing downward, and multiple spray nozzles 7 are provided on the cone surface of the cone-shaped chemical outlet 6.

[0021] In this invention, the telescopic nozzles are used in groups, with each nozzle independently connected to the pesticide. The telescopic nozzles can adjust the relative positions of the fixed cylinder 1 and the telescopic cylinder 2 under the action of the electric cylinder 3, thereby adjusting the extension and retraction of the pesticide outlet 6. This allows the pesticide outlet 6 to extend underwater, spraying the pesticide from the spray nozzle 7 into the water, preventing the pesticide from floating on the surface and hindering its diffusion. The cone-shaped pesticide outlet 6 has multiple spray nozzles 7, with the openings of the nozzles 7 tilted downwards, allowing the sprayed pesticide to reach deeper waters more quickly and increasing the diffusion speed. When spraying a second pesticide, waiting time is reduced, improving the overall efficiency of pesticide spraying.

[0022] Furthermore, a sliding groove 5 is provided on the side of the fixed cylinder 1, and a connecting block 4 is installed at one end of the electric cylinder 3. The connecting block 4 passes through the sliding groove 5 and is fixedly connected to the telescopic cylinder 2. By providing the sliding groove 5 and the connecting block 4, the movement of the connecting block 4 is restricted by the sliding groove 5, reducing the problem of the electric cylinder 3 shifting when subjected to external forces.

[0023] Furthermore, an inner cylinder 11 is fixedly connected to the fixed cylinder 1 via a side plate 13, and the telescopic cylinder 2 is sleeved on the outside of the inner cylinder 11.

[0024] Furthermore, it also includes a drug inlet pipe 9, one end of which is fixedly connected to a mounting plate 10. The mounting plate 10 is provided with external threads, and the top of the fixed cylinder 1 is provided with internal threads. The mounting plate 10 is connected to the top of the fixed cylinder 1 by a threaded connection, so that the drug inlet pipe 9 and the fixed cylinder 1 are detachably connected. By setting the mounting plate 10 and connecting it to the fixed cylinder 1 by a threaded connection, the drug inlet pipe 9 is firmly connected to the inner cylinder 11 after connection, thereby making the delivery of medicine more stable.

[0025] like Figure 4 , Figure 5As shown, furthermore, a blade 12 is installed inside the spray nozzle 7. The inward-facing end of the blade 12 is the cutting edge, and the outward-facing end is the back of the blade. The blade tip is relatively sharp, which can collide and cut large clumps of medicine particles before they are sprayed out of the spray nozzle 7, dispersing them into several particles that fall into the water. This prevents clumps of medicine particles from quickly settling due to their weight, which would result in sedimentation before they could exert their dominant effect, leading to poor or even ineffective use of the medicine. Moreover, the side of the blade 12 facing the outside of the medicine outlet 6 is the back of the blade, which is wider, improving the effect of quickly spraying the medicine to both sides, achieving multi-directional spraying, a wider spraying range, and further improving the spraying efficiency of the medicine.

[0026] Furthermore, a locator 8 is installed at the bottom of the pesticide outlet 6. The locator 8 connects to the spraying vessel via Bluetooth, allowing workers to determine which areas have been sprayed, facilitating marking and enabling spraying of large areas of water. It also avoids repeated spraying of the same area, preventing both time and pesticide waste. The Bluetooth transmission between the locator 8 and itself is a mature existing technology. The locator 8 only participates in positioning; marking the water area requires human intervention and the existing control system of the spraying vessel. The control system detects the worker's control of the suction pump (on or off) to confirm information, and, in conjunction with the landmark information from the locator 8, completes the marking of the water area (whether the area has been sprayed).
