Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic cell protective covers, and in particular to a dustproof and alkaline liquid splashproof protective cover for an alkaline hydrogen production electrolytic cell. Background Technology

[0002] Existing alkaline hydrogen production electrolyzers typically employ open or semi-closed structures, with some units equipped with simple metal or plastic dust covers, but lacking comprehensive protection against alkaline splashes. The existing technology suffers from the following problems:

[0003] 1. Easily causes hydrogen accumulation: Due to the high permeability and low density of hydrogen, a small amount of hydrogen will seep out around the equipment during operation. Most existing protective covers are arc-shaped, which easily causes hydrogen accumulation.

[0004] 2. High risk of alkaline splashing: Electrolytic cells operate under high temperature and pressure. Thermal expansion and contraction, as well as the aging of gaskets, can easily lead to alkaline splashing, which can corrode nearby equipment and threaten the safety of inspectors and operators.

[0005] 3. Conflict between heat dissipation and sealing: Most existing protective covers are fully enclosed structures, which can prevent dust but hinder heat dissipation, or are breathable structures but cannot prevent liquid splashing. Summary of the Invention

[0006] The technical problems to be solved by this utility model are that the arc-shaped protective cover is prone to hydrogen accumulation, the top protective cover cannot isolate alkaline spray, and the fully enclosed protective cover hinders heat dissipation.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a dustproof and alkaline liquid splashproof protective cover for an alkaline hydrogen production electrolyzer, including a dustproof cover and a protective cover. The dustproof cover is V-shaped and the protective cover is arc-shaped. The ends of the dustproof cover and the protective cover are connected to the mounting plate at the top of the stand. The dustproof cover is fixedly installed inside the protective cover. The protective cover is arranged to rotate horizontally. Sensors for detecting the passage of liquid droplets are arranged in an array on both sides of the stand. A rotation drive component for the protective cover is installed on the stand.

[0008] Preferably, auxiliary frames are fixed on both sides of the upright frame, and the sensor includes a laser emitter fixed on the top of the auxiliary frame and a laser receiver fixed on the bottom of the auxiliary frame. The laser emitter and the laser receiver are arranged in a one-to-one correspondence and are equidistant along the length of the auxiliary frame.

[0009] Preferably, connecting rods are fixed at an angle on both sides of the mounting plate, the dust cover is located between the connecting rods on the same side of the two mounting plates, and the dust cover is also connected between the two mounting plates.

[0010] Preferably, a cable is fixedly connected between the connecting rods on both sides of the mounting plate, and the cable is located at the top of the connecting rod.

[0011] Preferably, the protective cover is distributed on both sides of the mounting plate. The protective cover includes an arc-shaped segment at the top and a linear segment at the bottom. The bottom end of the linear segment is provided with a foot. When the protective cover is rotated to the point where the bottom end contacts the ground, the linear segment is in a vertical state.

[0012] Preferably, both ends of the mounting plate are horizontally rotatably arranged with connecting wheels. The connecting wheels are fixedly connected to the protective cover through a mounting frame. The mounting frame includes three rods fixedly connected to the outer side wall of the connecting wheels. The three rods are respectively connected to the two ends and the middle of the protective cover.

[0013] Preferably, a reinforcing rod is connected between adjacent rods, with the end of the reinforcing rod connected to the middle of the rod.

[0014] Preferably, the rotation drive includes two winches fixed on both sides of the bottom of the upright frame, with a winding rope wound on the winches. One end of the connecting wheel is provided with an arc-shaped groove, the winding rope is wound in the arc-shaped groove, and the end is fixedly connected to the connecting wheel.

[0015] Preferably, guide blocks are equidistantly arranged on both sides of the upright frame along the vertical direction, the winding rope passes through the guide blocks, and the guide blocks are rotatably equipped with ball bearings that contact the winding rope.

[0016] Preferably, a contact sensor is fixedly installed at the top of the protective cover, and the contact sensor signal is connected to the rotation drive component.

[0017] This utility model provides a dustproof and alkaline solution splash-proof protective cover for an alkaline hydrogen production electrolyzer, which has the following beneficial effects.

[0018] 1. The dust cover adopts a V-shaped structure, which, compared to the traditional arc-shaped protective cover, reduces the space for hydrogen to remain inside the cover, thus lowering the risk of hydrogen accumulation. The V-shaped design facilitates the diffusion of hydrogen along the slope, and combined with the adjustable opening and closing state of the protective cover, it further promotes air circulation, avoids safety hazards caused by increased hydrogen concentration, and adapts to the high permeability and low density characteristics of hydrogen.

[0019] 2. The protective cover can be adjusted in opening and closing by rotating the drive mechanism. When the equipment is running, the protective cover rotates until its bottom touches the ground, and its top arc-shaped section and bottom linear section form a closed protective space, which can effectively block the splashing of alkaline solution from the electrolytic cell caused by high temperature and pressure or aging of the gaskets. At the same time, the laser emitters and receivers on both sides of the stand form a detection array, which can monitor the alkaline solution splashing in real time, so as to facilitate timely response measures and protect the safety of nearby equipment and inspection and operation personnel.

[0020] 3. The protective cover features a rotatable design. When the equipment needs heat dissipation, it can be opened by a winch to increase airflow and solve the problem of poor heat dissipation in a fully enclosed structure. When protection is required, the protective cover closes to form a sealed space, preventing alkali splashes and dust intrusion. This flexible opening and closing method takes into account both protection and heat dissipation needs, ensuring that the electrolytic cell operates in a suitable environment.

[0025] like Figure 1 and Figure 2 As shown, this utility model provides a dustproof and alkaline liquid splashproof protective cover for an alkaline hydrogen production electrolyzer, including a dustproof cover 13 and a protective cover 6. The dustproof cover 13 is V-shaped and the protective cover 6 is arc-shaped. The ends of the dustproof cover 13 and the protective cover 6 are both connected to the mounting plate 2 at the top of the support frame 1. The dustproof cover 13 is fixedly installed inside the protective cover 6. The protective cover 6 is arranged in a horizontal rotational manner. Sensors 11 for detecting the passage of liquid droplets are arranged in an array on both sides of the support frame 1. The rotation drive component of the protective cover 6 is installed on the support frame 1.

[0026] By installing the uprights 1 at both ends of the electrolytic cell, and arranging dust covers 13 and protective covers 6 between the two uprights 1, the dust covers 13 are fixed in a V-shape, which can diffuse the overflowing hydrogen gas through the two inclined surfaces of the dust covers 13, preventing the hydrogen gas from accumulating at the top. The operating condition of the electrolytic cell is detected by the sensor 11. When alkali splashing occurs, the sensor 11 transmits a signal to the rotation drive, which controls the protective covers 6 to rotate rapidly, so that the two protective covers 6 located at the top of the uprights 1 rotate to the sides of the uprights 1, shielding and isolating the sides and part of the top of the electrolytic cell, and preventing alkali splashing from causing personal injury or equipment damage.

[0027] like Figure 1As shown. The support frame 1 has auxiliary frames 10 fixed on both sides. The sensor 11 includes a laser emitter fixed to the top of the auxiliary frame 10 and a laser receiver fixed to the bottom of the auxiliary frame 10. The laser emitter and laser receiver are arranged in a one-to-one correspondence and are equidistant along the length of the auxiliary frame 10. During sensor 11 installation, auxiliary frames 10 are installed on both sides of the support frame 1. The auxiliary frames 10 are located on both sides of the electrolytic cell and have a rectangular frame structure. A continuous laser is emitted from the top laser emitter and received by the bottom laser receiver. When a droplet passes through the laser path, it blocks part of the light, causing a decrease in the intensity of the light received by the laser receiver, generating a pulse electrical signal. This indicates that a droplet has passed through the auxiliary frame 10, and then the rotation drive is controlled to rotate the protective cover 6.

[0028] like Figure 1 and Figure 2 As shown. Connecting rods 3 are fixed obliquely on both sides of the mounting plate 2. The dust cover 13 is located between the connecting rods 3 on the same side of the two mounting plates 2, and the dust cover 13 is also connected between the two mounting plates 2. Connecting rods 3 are fixedly installed on both sides of the mounting plate 2, and the dust cover 13 is fixedly installed through the connecting rods 3. The dust cover 13 is V-shaped, which not only guides the flow of hydrogen but also covers the top of the electrolytic cell, reducing dust pollution.

[0029] like Figure 2 As shown, to improve the installation strength of the dust cover 13, a cable 14 is fixedly connected between the connecting rods 3 on both sides of the mounting plate 2, with the cable 14 located at the top of the connecting rod 3.

[0030] like Figure 1 As shown. The protective cover 6 is distributed on both sides of the mounting plate 2. The protective cover 6 includes an arc-shaped section at the top and a linear section at the bottom. The bottom end of the linear section is provided with a foot. When the protective cover 6 is rotated until the bottom end contacts the ground, the linear section is in a vertical state. When the protective cover 6 isolates the electrolytic cell, by driving the protective cover to rotate, the foot at the bottom end of the protective cover 6 rests on the ground, and the linear section is in an upright state, ensuring the stability of the arrangement of the protective cover 6.

[0031] like Figure 1 As shown. Connecting wheels 4 are horizontally rotatably arranged at both ends of the mounting plate 2. The connecting wheels 4 are fixedly connected to the protective cover 6 via a mounting frame 5. The mounting frame 5 includes three rods fixedly connected to the outer walls of the connecting wheels 4, and the three rods are respectively connected to the two ends and the middle of the protective cover 6. By setting up the mounting frame 5, the connecting wheels 4 are fixedly connected to the protective cover 6. By driving the connecting wheels 4 to rotate, the rotation of the protective cover 6 can be achieved.

[0032] like Figure 1As shown, to increase the structural strength of the mounting bracket 5, a reinforcing rod 12 is connected between adjacent rods, with the end of the reinforcing rod 12 connected to the middle of the rod.

[0033] like Figure 1 As shown, to achieve the rotation drive of the connecting wheel 4, the rotation drive component includes two winches 7 fixed on both sides of the bottom of the upright frame 1. A winding rope 8 is wound around the winches 7. One end of the connecting wheel 4 is provided with an arc-shaped groove, and the winding rope 8 is wound within the arc-shaped groove, with its end fixedly connected to the connecting wheel 4. When the protective cover 6 is lowered, the winches 7 are controlled to unwind the winding rope 8. During the unwinding process, the protective cover 6 falls under its own weight, and the winches 7 can control the speed of the falling protective cover 6 to prevent damage during the fall.

[0034] like Figure 1 As shown, to achieve motion control of the winding rope 8, guide blocks 9 are equidistantly arranged vertically on both sides of the upright frame 1. The winding rope 8 passes through the guide blocks 9, and the guide blocks 9 are rotatably equipped with ball bearings that contact the winding rope 8. The movement path of the winding rope 8 is controlled by the guide blocks 9, and the ball bearings inside the guide blocks 9 can reduce the wear of the winding rope 8.

[0035] In a preferred embodiment of this utility model, a contact sensor is fixedly installed at the top of the protective cover 6, and the contact sensor signal is connected to the rotation drive component. When the protective cover 6 is rotated above the upright 1, the tops of the two protective covers 6 contact each other. At this time, the contact sensor is triggered, transmitting a signal to the winch 7. The winch 7 stops winding the winding rope 8, thereby locking the position of the protective cover 6.
