[0032] Example 1

[0033] Reference Figure 1 - Fig. 9 , provides a filter screen for the air inlet of a compressor of a gas turbine power plant, including an air inlet mechanism 100, which includes an air duct 101 and a floor 102, a storage portion 103 and a filter portion 104 arranged on the air duct 101, and a plug-in portion 105 arranged on the filter portion 104.

[0034] Furthermore, the storage portion 103 includes a storage slot 103 a disposed on the air duct 101 , and a guide slot 103 b disposed on the air duct 101 .

[0035] The guide groove 103b and the storage groove 103a are interconnected.

[0036] Specifically, there are two guide grooves 103 b , and the two guide grooves 103 b are respectively disposed on both sides of the air duct 101 .

[0037] Furthermore, the filter unit 104 includes a first filter plate 104a, a second filter plate 104b and a third filter plate 104c disposed inside the storage tank 103a, and a bar 104d disposed on the first filter plate 104a.

[0038] The first filter plate 104a is located on the top of the second filter plate 104b, and the second filter plate 104b is located on the top of the third filter plate 104c.

[0039] Specifically, the first filter plate 104a, the second filter plate 104b and the third filter plate 104c have the same size.

[0040] The first filter plate 104a, the second filter plate 104b and the third filter plate 104c are all connected to the strip rod 104d at one side adjacent to the guide groove 103b.

[0041] Furthermore, the plug-in portion 105 includes a first plug rod 105 a disposed on the first filter plate 104 a and a first plug hole 105 b disposed on the air duct 101 .

[0042] The top of the first filter plate 104a is connected to the first plugging rod 105a. There are two first plugging rods 105a, and the two first plugging rods 105a are evenly arranged on the top of the first filter plate 104a.

[0043] The first plug hole 105 b is located at the top of the air duct 101 .

[0044] Specifically, when the first filter plate 104a contacts the top surface inside the storage groove 103a, the first plug rod 105a is inserted into the first plug hole 105b, and the position of the first filter plate 104a is restricted by the first plug rod 105a and the first plug hole 105b to prevent the wind from blowing the first filter plate 104a away.

[0045] Operation process: In order to prevent larger debris from entering the interior of the air duct 101, it is necessary to block it with a filter. When installing the filter, the staff can stack the first filter plate 104a, the second filter plate 104b and the third filter plate 104c from top to bottom in sequence. The bottom of the first filter plate 104a and the top of the second filter plate 104b can be set to be plug-in, and the bottom of the second filter plate 104b and the top of the third filter plate 104c can be set to be plug-in. After the first filter plate 104a, the second filter plate 104b and the third filter plate 104c are set, the top of the first filter plate 104a does not contact the top surface inside the storage tank 103a.

[0046] Example 2

[0047] Reference Figure 2 - Fig.10This embodiment is different from the first embodiment in that: the locking mechanism 200 includes a receiving groove 201 arranged on the air duct 101, a telescopic portion 202 arranged on the receiving groove 201, a limiting portion 203 arranged on the telescopic portion 202, a first through-hole 204, a chamber 205 and a second through-hole 206 arranged on the filter portion 104, a locking portion 207 arranged inside the chamber 205, and an unlocking portion 208 arranged on the locking portion 207.

[0048] The receiving groove 201 and the storage groove 103 a are interconnected, and the storage groove 103 a is located between the receiving groove 201 and the air inlet of the air duct 101 .

[0049] The second filter plate 104b is provided with a first through-hole 204, a chamber 205 and a second through-hole 206. The first through-hole 204 is located at a side adjacent to the receiving groove 201, and the second through-hole 206 is located at a side away from the storage groove 103a.

[0050] Specifically, the first through-hole 204 and the chamber 205 are interconnected, and the chamber 205 and the second through-hole 206 are interconnected.

[0051] Furthermore, the telescopic portion 202 includes a fixed rod 202a disposed inside the receiving groove 201, a slider 202b disposed on the fixed rod 202a, and a first spring 202c disposed on the slider 202b;

[0052] There are two fixing rods 202 a , and both fixing rods 202 a are installed inside the receiving groove 201 .

[0053] The sliding block 202b is sleeved on the side wall of the fixing rod 202a.

[0054] One end of the first spring 202 c is connected to the side wall of the slider 202 b , and the other end of the first spring 202 c is connected to the inner wall of the accommodating groove 201 .

[0055] Specifically, when the spring is not subjected to force, one side of the slider 202b is horizontally parallel to the inner wall of the storage slot 103a.

[0056] Furthermore, the limiting portion 203 includes a limiting block 203a disposed on the slider 202b and a slot 203b disposed on the first filter plate 104a.

[0057] The side of the slider 202b away from the first spring 202c is connected to the limiting block 203a. The limiting block 203a is located in a right triangle, and the inclined surface of the limiting block 203a faces downward.

[0058] Wherein, slots 203b are disposed on both sides of the first filter plate 104a, and the slots 203b are adjacent to the bottom of the first filter plate 104a.

[0059] Specifically, when the top of the first filter plate 104a contacts the top surface inside the storage groove 103a, the limiting block 203a is located inside the slot 203b. The position of the first filter plate 104a is fixed by the setting of the limiting block 203a.

[0060] Specifically, when the staff places the first filter plate 104a inside the storage groove 103a, the first filter plate 104a is pushed upward, so that the first filter plate 104a drives the strip rod 104d to move upward inside the guide groove 103b. During the rising process of the first filter plate 104a, the inclined surface on the limiting block 203a can be squeezed, and the limiting block 203a drives the slider 202b to slide on the side wall of the fixed rod 202a, and the slider 202b drives the first spring 202c to contract. When the limiting block 203a is aligned with the slot 203b, the first spring 202c recovers and drives the slider 202b, and the slider 202b drives the limiting block 203a to be inserted into the inside of the slot 203b for locking.

[0061] Furthermore, the locking portion 207 includes a third through hole 207a disposed on the first filter plate 104a, a fixing block 207b disposed inside the chamber 205, a short rod 207c disposed on the fixing block 207b, a U-shaped clip 207d disposed on the short rod 207c, and a guide block 207e disposed on the U-shaped clip 207d.

[0062] The third through hole 207a is disposed at the bottom of the first filter plate 104a, and the third through hole 207a and the slot 203b are interconnected.

[0063] The fixing block 207 b is located at the top of the first through hole 204 .

[0064] The short rod 207c is located at the center of the fixing block 207b, and the short rod 207c can slide on the fixing block 207b.

[0065] One end of the short rod 207c adjacent to the first filter plate 104a is connected to the U-shaped clip 207d.

[0066] Specifically, when the second filter plate 104b contacts the first filter plate 104a, both ends of the top of the U-shaped clip 207d can enter into the interior of the slot 203b through the third through-hole 207a.

[0067] The guide block 207e is in a right triangle shape, which is convenient for limiting the U-shaped clip 207d so that the second filter plate 104b will not fall off.

[0068] Specifically, when installing the second filter plate 104b, the staff follows the steps of installing the first filter plate 104a to make the second filter plate 104b approach the first filter plate 104a, and the second filter plate 104b can drive the guide block 207e to contact the inner wall of the third through-hole 207a. The guide block 207e is squeezed, so that the two guide blocks 207e are close to each other, and the guide block 207e drives the U-shaped clip 207d to shrink inward. When the guide block 207e completely enters the interior of the slot 203b, the U-shaped clip 207d is restored, and the guide block 207e buckles the first filter plate 104a to prevent the second filter plate 104b from falling.

[0069] Furthermore, the unlocking portion 208 includes a pressing block 208a disposed on the U-shaped clip 207d, and a first cut surface 208b disposed on the pressing block 208a.

[0070] The two ends of the U-shaped clip 207d that are away from each other are both connected to the extrusion block 208a.

[0071] A first cut surface 208b is disposed on a side of the two extrusion blocks 208a that are away from each other.

[0072] Specifically, when the U-shaped clamp 207d rises, the U-shaped clamp 207d drives the extrusion block 208a to rise, and the first section 208b of the extrusion block 208a is squeezed by the third through hole 207a, so that the two ends of the U-shaped clamp 207d are tightened, making it convenient for the staff to separate the first filter plate 104a and the second filter plate 104b.

[0073] Operation process: when it is necessary to fix the second filter plate 104b on the first filter plate 104a, the staff only needs to put the second filter plate 104b into the storage slot 103a, so that the bar block on the second filter plate 104b is located at the temporal part of the guide slot 103b. At this time, the staff pushes the second filter plate 104b upward to make the second filter plate 104b rise, and the second filter plate 104b drives the fixed block 207b to rise, and the fixed block 207b drives the U-shaped clip 207d to rise, and the U-shaped clip 207d drives the guide block 207e to squeeze the third through-hole 207a, so that the guide block 207e enters the interior of the slot 203b, and the second filter plate 104b is fixed.

[0074] Example 3

[0075] Reference Figure 1 - Fig.10 This embodiment is different from the above embodiments in that: the stabilizing mechanism 300 includes a slide bar 301 arranged on the locking portion 207 , a pressing portion 302 and a lifting portion 303 arranged on the slide bar 301 , and a hanging portion 304 arranged on the lifting portion 303 .

[0076] The bottom of the fixed block 207 b is connected to the sliding rod 301 , and one end of the sliding rod 301 away from the fixed block 207 b is connected to the inner wall of the chamber 205 .

[0077] Specifically, there are two sliding bars 301 , and the two sliding bars 301 are evenly arranged on the fixing block 207 b .

[0078] Furthermore, the pressing portion 302 includes an L-shaped rod 302a disposed on the slide bar 301, a second cut surface 302b disposed on the L-shaped rod 302a, and an inclined rod 302c disposed on the slider 202b.

[0079] The L-shaped rod 302 a is sleeved on the side walls of the two sliding rods 301 .

[0080] Specifically, the bottom of the L-shaped rod 302a contacts the bottom of the first through-hole 204, and the other end of the L-shaped rod 302a is located outside the second filter plate 104b.

[0081] The second cut surface 302b is located at the top of the other end of the L-shaped rod 302a.

[0082] The bottom of the slider 202b is connected to the inclined rod 302c.

[0083] Specifically, when the first filter plate 104a contacts the second filter, the second cut surface 302b contacts the inclined rod 302c. When the L-shaped rod 302a rises, the L-shaped rod 302a can drive the second cut surface 302b to squeeze the inclined rod 302c, the inclined rod 302c drives the slider 202b to move, and the slider 202b drives the first spring 202c to contract.

[0084] Furthermore, the lifting part 303 includes a lifting block 303a arranged on the sliding rod 301, a bolt 303b and a lifting rod 303c arranged on the lifting block 303a, a fixing hole 303d arranged on the second filter plate 104b, a sliding cavity 303e arranged on the third filter plate 104c, a second plug rod 303f arranged inside the sliding cavity 303e, a second spring 303g arranged on the second plug rod 303f, and a second socket 303h arranged on the floor 102.

[0085] The lifting block 303 a is movably sleeved on the side wall of the sliding rod 301 , and a space for insertion is reserved on a side of the lifting block 303 a away from the second through hole 206 .

[0086] The lifting block 303a is connected to a bolt 303b at one side adjacent to the second through hole 206 .

[0087] Specifically, the bolt 303b can be rotated to adjust the insertion depth of the bolt 303b on the lifting block 303a.

[0088] The bottom of the lifting block 303a is connected to the lifting rod 303c, the lifting rod 303c is located between the two sliding rods 301, and the bottom end of the lifting rod 303c can penetrate to the outside of the second filter plate 104b.

[0089] The fixing hole 303d and the chamber 205 are interconnected.

[0090] The sliding cavity 303 e is located directly below the chamber 205 .

[0091] The cross section of the second insertion rod 303f is in a "T" shape, which can prevent the second insertion rod 303f from escaping from the inside of the sliding cavity 303e.

[0092] A second spring 303g is disposed on the top of the second insertion rod 303f, and the second spring 303g is located inside the sliding cavity 303e.

[0093] Specifically, under normal circumstances, the second insertion rod 303f is completely located inside the sliding cavity 303e.

[0094] Specifically, the sum of the height dimensions of the first filter plate 104a, the second filter plate 104b and the third filter plate 104c is greater than the height dimension of the air inlet of the air duct 101, so that the staff can place the third filter plate 104c below the second filter plate 104b conveniently.

[0095] Specifically, when the third filter plate 104c is located directly below the second filter plate 104b, the sliding cavity 303e is located directly above the second insertion hole 303h, and the lifting rod 303c can be lowered and inserted into the second insertion hole 303h.

[0096] Furthermore, the hanging portion 304 includes a protrusion 304a disposed on the L-shaped rod 302a, and a through hole 304b disposed on the protrusion 304a.

[0097] A protrusion 304a is installed at the bottom of the L-shaped rod 302a.

[0098] Specifically, when the lifting block 303a rises, the protrusion 304a can be located below the lifting block 303a, so that the lifting block 303a overlaps with the protrusion 304a. At this time, the staff can rotate the bolt 303b so that the bolt 303b is inserted into the through hole 304b to fix the position of the lifting block 303a.

[0099] Operation process: When the staff installs the third filter plate 104c, the staff first places the third filter plate 104c inside the storage groove 103a, and the third filter plate 104c is located at the bottom of the second filter plate 104b. At this time, the staff rotates the bolt 303b to disengage the bolt 303b from the inside of the through hole 304b. At this time, under the action of gravity, the lifting block 303a slides downward, and the lifting block 303a drives the lifting rod 303c to descend, and the lifting rod 303c enters the sliding cavity. Inside 303e, the staff can press down the bolt 303b, and the bolt 303b drives the lifting block 303a to continue to descend. The lifting block 303a drives the lifting rod 303c to descend and squeeze the second plug rod 303f. The second plug rod 303f drives the second spring 303g to extend, and the second plug rod 303f is inserted into the second hole 303h. At this time, the staff turns the bolt 303b to make the bolt 303b enter the fixing hole 303d to complete the installation of the third filter plate 104c.

[0100] In order to ensure the sealing between the second filter plate 104b and the third filter plate 104c, it is necessary to make the first filter plate 104a and the second filter plate 104b drop a distance together. At this time, the staff pushes the L-shaped rod 302a upward, and the L-shaped rod 302a drives the second cut surface 302b to squeeze the inclined block. The inclined block drives the slider 202b to squeeze the first spring 202c to contract, and the slider 202b drives the limiting block 203a to disengage from the inside of the slot 203b. At this time, under the action of gravity, the first filter plate 104a and the second filter plate 104b drop together, so that the bottom of the second filter contacts the third filter plate 104c. After the first filter plate 104a drops a distance, it can still cover the air inlet of the air duct 101. The first plug rod 105a is still located inside the first plug hole 105b. At this time, the limiting block 203a contacts the side wall of the first filter plate 104a, and the first spring 202c is in a contracted state. The entire air duct 101 is covered by the first filter plate 104a, the second filter plate 104b and the third filter plate 104c.

[0101] When it is necessary to clean the first filter plate 104a, the second filter plate 104b and the third filter plate 104c, the staff rotates the bolt 303b so that the bolt 303b is disengaged from the inside of the fixing hole 303d. At this time, the bolt 303b is pushed upward, and the bolt 303b drives the lifting block 303a to rise. The lifting block 303a drives the lifting rod 303c to disengage from the inside of the third filter plate 104c. The second spring 303g recovers and drives the second plug 303f to enter the inside of the sliding cavity 303e. At this time, the staff can separate the third filter plate 104c from the second filter plate 104b, and the first filter plate 104c can be cleaned. The plate 104a and the second filter plate 104b can be removed from the air duct 101, and then the first filter plate 104a needs to be separated from the second filter plate 104b. The staff pushes the L-shaped rod 302a upward, and the L-shaped rod 302a rises to squeeze the short rod 207c. The short rod 207c drives the U-shaped clip 207d to rise, so that the squeezing block 208a is squeezed by the inner wall of the third through-hole 207a, so that the two guide blocks 207e are close to each other. At this time, the staff can lift the first filter plate 104a from the top to separate the first filter plate 104a from the second filter plate 104b, which is convenient for the staff to clean.
