Description

Technical Field

[0001] This utility model belongs to the field of nearshore photography technology, and more specifically, it relates to an anti-interference device for nearshore photogrammetry. Background Technology

[0002] Anti-interference equipment for nearshore photogrammetry is a device used to ensure that photogrammetric equipment can acquire images and data stably and accurately in nearshore environments, and to reduce or eliminate the influence of various interference factors. There are many types of anti-interference equipment for nearshore photography, among which anti-interference equipment that reduces the interference of wind on photographic equipment is one of them.

[0003] The stability of existing anti-interference equipment has room for improvement, which affects its anti-interference effect on photographic equipment. It is not possible to improve its own stability through multiple stabilizing structures. Existing wind interference resistance equipment is not convenient and quick enough to remove and dismantle ground stakes, which affects the overall removal efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an anti-interference device for near-shore photogrammetry. This addresses the issues that existing anti-interference devices have room for improvement in stability, which affects their anti-interference effect on photogrammetric equipment, and cannot improve their stability through multiple stabilizing structures. Furthermore, existing wind-resistant anti-interference devices are not convenient or quick enough to remove and retract ground stakes, affecting the overall removal efficiency.

[0005] The purpose and effectiveness of this utility model's anti-interference device for near-shore photogrammetry are achieved through the following specific technical means:

[0006] An anti-interference device for near-shore photogrammetry includes a base; the base is fixed to the ground by four ground nails, and a cylindrical rod-shaped mounting rod is welded to the top surface of the base. A fixing assembly is installed on the mounting rod, which consists of a connecting seat, an electric cylinder, and an electric clamp. A connecting seat slides on the mounting rod, and a screw for locking and positioning the connecting seat on the mounting rod is threaded onto the connecting seat. An electric cylinder is fixed to the left end face of the connecting seat, and an electric clamp is fixed to the extended end of the electric cylinder.

[0007] Furthermore, all four ground nails have a stepped structure, and a ring-shaped support is welded to the top surface of the base. The top surface of the support contacts the stepped parts of the four ground nails.

[0008] Furthermore, a rain shield is fixed to the top surface of the mounting rod. The rain shield is located above the electric clamp and serves as a shield for the photographic equipment.

[0009] Furthermore, a protective cover slides on the mounting rod, and a screw for positioning the protective cover on the mounting rod is threaded onto the protective cover. A battery is fixed to the top surface of the inner wall of the protective cover.

[0010] Furthermore, a waterproof switch is fixed to the top surface of the protective cover. The waterproof switch is electrically connected to the battery and also electrically connected to the electric cylinder and the electric clamp.

[0011] Furthermore, a barrel slides on the mounting rod, and a discharge pipe is welded to the outer wall of the barrel. A valve is installed on the discharge pipe, and the barrel serves as a stabilizing component for the base.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In terms of stability enhancement, the device design is extremely ingenious. The base is firmly fixed to the ground by four stepped ground spikes. The ground spikes cooperate with the ring support welded to the top of the base, which not only enhances the stability of the fixation, but also greatly improves the efficiency of disassembly by using a pry bar inserted into the gap between the ground spikes and the base. In addition, the sliding barrel on the mounting rod can be filled with seawater during use, which can significantly increase the overall weight of the device, thereby further improving the stability of fixing the photography equipment and effectively reducing the interference of external wind on the stability of the photography equipment, ensuring that the equipment will not be affected by the swaying of the wind during the shooting process, thus affecting the shooting quality.

[0014] In terms of ease of operation, this device also excels. The design of the fixing components is ingenious; the connecting seat that slides on the mounting rod can be locked in place using a screw. An electric cylinder fixed to the left end of the connecting seat extends to an electric clamp. In actual operation, simply extending the electric cylinder allows the electric clamp to quickly move to the camera equipment bracket and clamp it, making operation simple and convenient, greatly improving the efficiency of assisting in fixing the camera equipment bracket. Furthermore, the waterproof switch on the top of the protective cover is electrically connected to the battery, electric cylinder, and electric clamp; pressing the waterproof switch easily drives the electric cylinder and electric clamp, ensuring safe and convenient operation.

[0015] From a protective perspective, the device offers excellent protection. The rain shield fixed to the top of the mounting rod, positioned above the electric clamp, effectively shields the photographic equipment during rainy weather, preventing water damage and minimizing interference with photogrammetry work, thus protecting the equipment's normal operation. Simultaneously, the sliding protective cover on the mounting rod is not only positioned by screws, but also provides effective waterproof protection for the battery fixed to its inner top surface, preventing damage from rainwater and ensuring the device's power supply. This, in turn, guarantees the stable operation of the entire auxiliary mounting device. Attached Figure Description

[0027] As attached Figure 1 To be continued Figure 6 As shown:

[0028] This utility model provides an anti-interference device for near-shore photogrammetry, including a base 1. The base 1 is fixed to the ground by four ground nails 102. A cylindrical rod-shaped mounting rod 101 is welded to the top surface of the base 1. A fixing component 2 is installed on the mounting rod 101. The fixing component 2 consists of a connecting seat 201, an electric cylinder 202, and an electric clamp 203. A connecting seat 201 slides on the mounting rod 101, and a screw for locking and positioning the connecting seat 201 on the mounting rod 101 is threaded onto the connecting seat 201. An electric cylinder 202 is fixed to the left end of the connecting seat 201, and an electric clamp 203 is fixed to the extended end of the electric cylinder 202. When assisting in fixing the support of the photogrammetry equipment, the base 1 is fixed to the ground by the four ground nails 102. The electric cylinder 202 is driven to extend until the electric clamp 203 moves to the support of the photogrammetry equipment. The electric clamp 203 is then driven to clamp the photogrammetry equipment frame. This device can reduce the interference of external wind force on the stability of the photogrammetry equipment.

[0029] The four ground spikes 102 are all stepped structures. A ring-shaped support 103 is welded to the top surface of the base 1. The top surface of the support 103 contacts the stepped part of the four ground spikes 102. When disassembling the ground spikes 102, a pry bar can be inserted into the gap between the ground spikes 102 and the base 1 to pry them, which improves the disassembly efficiency of the ground spikes 102 and thus improves the retraction efficiency of the device.

[0030] A rain shield 104 is fixed to the top surface of the mounting rod 101. The rain shield 104 is located above the electric clamp 203. The rain shield 104 is a shield for the photographic equipment. During use, the rain shield 104 can shield the photographic equipment from rain and reduce the interference of rain on photogrammetry.

[0031] A protective cover 3 slides on the mounting rod 101. A screw for positioning the protective cover 3 on the mounting rod 101 is threaded onto the protective cover 3. A storage battery 301 is fixed to the top surface of the inner wall of the protective cover 3.

[0032] The top surface of the protective cover 3 is fixed with a waterproof switch 302. The waterproof switch 302 is electrically connected to the storage battery 301. The waterproof switch 302 is also electrically connected to the electric cylinder 202 and the electric clamp 203. During use, pressing the waterproof switch 302 can drive the electric cylinder 202 and the electric clamp 203 to work, and the protective cover 3 can achieve waterproof protection for the storage battery 301. Example

[0033] Based on Embodiment 1, a barrel 4 slides on the mounting rod 101. A discharge pipe 401 is welded to the outer wall of the barrel 4, and a valve is installed on the discharge pipe 401. The barrel 4 is a stabilizing component of the base 1. During use, some seawater is added into the barrel 4, which can improve the stability of the device and thus improve the stability of fixing the photography equipment.

[0034] Working principle: When assisting in fixing the camera equipment bracket, the base 1 is fixed to the ground by four ground stakes 102. Pressing the waterproof switch 302 drives the electric cylinder 202 to extend until the electric clamp 203 moves to the camera equipment bracket. Pressing the waterproof switch 302 drives the electric clamp 203 to clamp the camera equipment frame. Add some seawater to the bucket 4 to fill it. When installing this device, ensure that the rain shield 104 is above the camera equipment. When retracting after use, open the valve on the drain pipe 401 to drain the seawater from the bucket 4. Use a pry bar to pry open the gap between the ground stakes 102 and the base 1 to remove the ground stakes 102.
